본 연구는 보조공학기기를 사용하고 있는 장애인근로자의 작업수행 효과와 그 영향 요인이 무엇인가를 고찰해보고, 개선방안을 모색해보는데 있다. 분석을 위해 장애인고용공단의 ‘2013년 보조공학기기 및 서비 스 만족도 조사’ 자료를 활용하였으며, 연구결과는 다음과 같다. 첫째, 보조공학기기 자체에 대한 만족도 영역에서도 ‘무게 만족’ 영역 점수가 상대적으로 낮았으며, 지원 서비스 영역별 만족도 ‘공단의 정보 내용’ 영역의 만족도가 가장 낮았다. 한편, 작업수행 효과영역에서도 생산성 향상에 대한 변화 인식이 가장 적은 것으로 나타났다. 둘째, 보조공학기기의 작업수행 효과는 장애정도가 중증일수록, 3차 산업에 종사하는 경우, 보조공학기기 자체 만족도, 서비스 및 지원제도 만족도가 높을수록 큰 것으로 나타났다. 그러므로 단기적으로 보조공 학기기 사용의 작업 효과를 향상시키기 위해서는 관련 변인들에 영향을 줄 수 있는 적극적인 정책이 요구 되고 있다. 한편, 장기적으로 경증장애인이나 1·2차 산업에 종사하는 장애인근로자등에게도 작업 효과가 나 타날 수 있도록 보조공학기기 관련 정책들이 마련되어야 할 것이다. 결론적으로, 보조공학기기의 작업수행 효과를 개선시키기 위해서는 지원서비스 전달체계 개선은 물론 맞춤제작 보조공학기기의 보급지원이 활성화될 수 있도록 제도개선을 해야 할 것이다. 더구나, 맞춤형 사회 보장제도의 실시와 발을 맞추어 보조공학기기 지원 분야에서도 장애인의 개별특성에 맞는 보조공학기기 서비스 전문화가 강화되어야 할 것이다.

This study focused on analysing the effects of working performance and it’s affecting factors of disabled workers with assistive technologies. We used the survey of KEAD ‘2013 Assistive Technologies and Service Satisfaction’ and the findings as follows : First, the satisfaction of ‘Weight’ in assistive technologies(below ‘AT’), the satisfaction of ‘Contents of information by agency’ in service, and the satisfaction of ‘Productivity’ in working performance were relatively less than any other factors. Second, the effects of working performance with AT were higher in case of lower degree of disability, engaged in 3rd industries and the higher satisfaction of AT itself, service and supporting system of AT. Therefore, the influence of related variables should be increase in short-term through the more positive AT policy in order to enhance the effects of working performance. In long-term, the relative lower satisfaction should be more improved irrespective of disability degree and engaged industries. In conclusion, it is necessary of improving AT supply and supporting systems to increase the effects of working performance for disabled workers. Recently customized welfare policy system was executed in public assistance schemes. Likewise AT policy should be considered the individual characteristics of workers with disabilities and customized AT service should be strengthened by introducing and revitalizing so-called expert service center of AT.

Empirical research is warranted to determine effective ways to utilize paired associate music to facilitate recall and learning. The purpose of this study was to isolate and determine the effects of mode and rhythm on working memory as measured by sequential digit recall performance. Participants were music majors (n=30) and nonmusic majors (n=30) at a large comprehensive university. Participants listened to six different treatment stimuli of monosyllabic digits paired with: (a) a major melody and rhythm, (b) a natural minor melody and rhythm, (c) a mixolydian melody and rhythm, (d) a major melody without rhythm, (e) a natural minor melody without rhythm, and (f) a mixolydian melody without rhythm. Results indicated a significant interaction between mode and rhythm, demonstrating that rhythm facilitated recall most during the natural minor mode condition but not during the mixolydian mode condition. Analyses of estimated marginal means indicated that participants were able to recall information paired with major modes best, followed by minor and mixolydian modes, respectively. Additionally, participants were able to recall information paired with melodies that contained a rhythmic component better than information paired with melodies without a rhythmic component. Although not significant, music majors tended to slightly outperform nonmusic majors. Consistent with previous research, participants were able to recall information in primacy and recency serial positions most accurately. From the results of this study, memory and learning may be enhanced by pairing information with major melodies and rhythm. Limitations, implications for clinical practice, and suggestions for future research are provided.

조직 내 정치(organizational politics)와 갈등(organizational conflicts)는 여느 조직에나 존재하는 일상적인 현상이고, 조직산출 및 성과에 영향을 주는 핵심적인 요인이라 할 수 있지만, 조직 관련 연구에서 배제되어 왔으며, 특히 국내 공공조직을 대상으로 한 연구 및 행정학 연구에서 본격적으로 연구가 진행되어 오지 않고 있다. 이러한 관점에서 본 연구는 조직 내 정치와 갈등이 주요한 조직산출 및 성과변수라 할 수 있는 직무만족과 조직성과에 어떠한 영향을 주는지 살펴보고자 한다. 특히 위계적 업무방식(top-down way of working)을 매개변수로 설정하여 보다 상세한 인과관계 분석을 시도하였다. 분석 결과 조직 내 정치는 위계적 업무방식에 정(+)의 영향을 주고 있었으며, 이를 매개하여, 직무만족과 조직성과에 부정적 영향을 주고 있었다. 부정적 유형의 조직 내 갈등인 관계갈등은 조직성과에 직접적인 부정적 영향을 주고 있었다. 조직 내 갈등은 위계적 업무방식에 유의한 영향을 주지는 않았지만, 조직 내 정치가 유의한 영향을 주었는데, 이는 직무만족과 조직성과에 매개하여 부정적 영향을 주고 있는 것으로 나타났다.

Organizational politics and conflicts are very natural phenomenon in any organization and very crucial factors affecting organizational outputs and outcomes. However, they would be neglected from the previous studies regarding public organization in Korean. Therefore, this study is to study the relationships between organizational politcs, conflicts, and organizational outputs and outcomes such as job satisfaction and organizational performance examining mediating effects of top-down way of working among the relationships. Based on the results, relationship conflict positively affects organizational performance. Furthermore, organizational politics increases top-down way of working and eventually negatively affects job satisfaction and organizational performance with the negative mediation effects of top-down way of working.

Purpose: The purpose of this study was to investigate whether the effects of emotional intelligence and working environment on nursing performance of nurses caring for cancer patients in small and medium hospitals were mediated by communication competence. Methods: The data was collected between Aug. 1 and Aug. 30, 2018 from 240 nurses caring for cancer patients from 11 small and medium hospitals in B city. Variables included in this study were the Wong and Law Emotional Intelligence Scale (WLEIS), the Practice Environment Scale of Nursing Work Index (PES-NWI), the Global Interpersonal Communication Competence (GICC), and nursing performance. The collected data were analyzed by t-tests, ANOVA and Scheffe’s test, Pearson’s correlation coefficients, and 3 step multiple regression using SPSS/WIN 24.0 and the Sobel test. Results: Communication competence, in the relationship between emotional intelligence and nursing working environment on nursing performance in nurses caring for cancer patients in small and medium hospitals, showed a partial mediating effect (Z=5.24, p<.001; Z=2.44, p=.001 respectively). Conclusion: The results of this study showed the effects of emotional intelligence and nursing working environment on nursing performance of nurses caring for cancer patients in small and medium hospitals were mediated by communication competence.

Purpose: The purpose of this study was to identify factors influencing nursing performance of nurses in long-term care hospitals. Methods: The participants were 200 nurses working in 14 long-term care hospitals in B and G cities. Data were collected from January 26 to April 30, 2015. SPSS/WIN 18.0 was used for analysis with t-test, ANOVA, Scheffe? test, Pearson correlation coefficients and Stepwise multiple regression. Results: There was a significant correlation between nursing performance and self-leadership (r=.63, p<.001) and self-efficacy (r=.66, p<.001). In the multiple regression, self-efficacy (β=.40, p<.001), self-leadership (β=.33, p<.001) and position (β=.11, p= .039) were associated with nursing performance. These factors accounted for 49% of the total variance in nursing performance. Conclusion: Considering the results of this study, educational programs to improve self-efficacy and self-leadership should be developed and implemented in order to foster nursing performance in the nurses working in long-term care hospitals.

The present study explores the effects of working memory on L2 English writing performance of Korean EFL college students. A total of 60 students were recruited and asked to complete both L1 Korean and L2 English working memory tests and write an argumentative essay in English. The performance of a written task in L2 was measured along the dimensions of fluency and complexity. The collected data was analysed quantitatively by using SPSS. The results showed that (1) there was no effect of L1 working memory on L2 writing performance except for lexical diversity; (2) working memory in L2 had a significant impact on fluency in L2 writing performance; (3) and there was an effect of working memory in L2 on lexical diversity, which is one of the measures of lexical complexity. However, there was no effect of L2 working memory on syntactic complexity. In the concluding part, these issues were discussed and directions for further research were suggested. (158 words)

An analytical and experimental study has been conducted to determine the optimal charging mass of working fluid for the maximum heat transport capacity of heat pipe with axially grooved wick. When the heat pipe is operated in a steady state, the liquid-vapor meniscus recession of working fluid to the bottom of groove is occurred in the evaporator region. In this work, the optimal charging mass of working fluid was obtained by considering the meniscus recession from the axial variation of capillary pressure, the radius of curvature and wetting angle of meniscus of liquid-vapor interface. Experimental results were also obtained by varying the charging mass of working fluid within a heat pipe, and presented for the trend of maximum heat transport capacity corresponding to the operating temperature and the elevation of heat pipe. Finally, the analytical results of the optimal charging mass of working fluid were compared with those from the experiment, both of which were in good agreement with each other.

The purpose of this study is to examine how gender and aging affect verbal fluency performance depending on the task types and how their performance is associated with working memory capacity in cognitively healthy Korean adults. A total of 120 normal adults (60 males and 60 females) residing in Korea, matched for age and education, were categorized into three age groups: younger (20-39 years), middle-aged (40-59 years), and older adults (60-79 years). Verbal fluency was assessed using semantic and verb fluency tasks. Working memory was evaluated through digit span tasks. Significant gender-related differences were found in verbal fluency tasks, with females consistently outperforming males in all tasks, particularly semantic fluency. Moreover, a noticeable decline in performance on verbal fluency tasks is observed among the different age groups, with young adults displaying the highest performance, followed by middle-aged and older adults. Remarkably, the interplay between task type and gender emphasizes that females excel in semantic fluency across all age groups. In younger and older groups, the fluency task that best distinguishes gender was the verb fluency task, and a significant correlation was observed between working memory and all verbal fluency tasks in male and female groups. These findings suggest that males may face challenges in specific verbal fluency tasks compared to females, potentially influenced by various factors and complex interactions.

This study investigated whether task complexity may affect L2 speaking performance as predicted by the Cognition Hypothesis (Robinson, 2011), and whether the effect of task complexity may interact with individual differences in working memory capacity. A total of twenty Korean advanced-level EFL learners performed two separate picture description tasks, which were different in task complexity along [+/- here and now] dimension. Their working memory was measured by an L1 version of a reading span task. The results showed that there was no significant difference between Here-and-Now task (i.e., a simple task) and There-and-Then task (i.e., a complex task) in terms of complexity, accuracy, and fluency of English speaking performance, rejecting the prediction of the Cognition Hypothesis. Yet, it found that working memory correlated with accuracy in L2 performance on the complex task, but not on the simple task. This indicates that the effect of individual learners’ working memory capacity is observable only when a task demands a high control of attentional resources. Conversely, when a task is simple, individual differences in working memory capacity do not result in significant differences in L2 speaking performance.

목적: 실어증 환자들이 전반적인 언어손상과 함께 작업기억 손상을 동반한다는 사실은 다양한 연구를 통해 밝혀졌다. 실어증 환자를 대상으로 작업기억 연구들이 꾸준히 증가하고 있음에도 실어증 환자의 언어 능력을 반영하는 작업기억을 효율적으로 측정하는 과제 유형에 대한 연구는 여전히 진행단계에 있다. 이에 자극 유형및 반응 순서에 따른 실어증 환자의 작업기억 과제 유형 별 수행력 차이를 살펴보고 각 작업기억 과제와 실어증 중증도의 상관관계를 분석하였다. 또한 실어증 중증도를 가장 잘 예측해줄 수 있는 요인은 무엇인지 알아보고자 하였다. 방법: 실어증 환자 16명을 대상으로 작업기억 과제와 한국판 웨스턴 실어증 평가를 실시하였다. 통계적 처리는 분산분석, 상관분석 및 회귀분석을 실시하였다. 결과: 작업기억 과제 유형에 따른 수행력분석 결과 숫자에 비해 단어에서, 바로 따라지시하기에 비해 거꾸로 따라지시하기에서 더 낮은 수행력을 보이는 것으로 나타났다. 또한 바로 따라지시하기에 비해 거꾸로 따라지시하기에서 발생하는 수행력의 저하가 단어에 비해 숫자일 때 유의하게 큰 것으로 분석되었다. 각 과제와 실어증 중증도 간 상관관계 분석 결과 숫자바로 및 거꾸로 따라지시하기 과제가 실어증 중증도와 유의한 상관관계를 보이는 것으로 나타났으며, 회기분석 결과 실어증 중증도를 유의하게 예측하는 요인은 숫자 바로 따라지시하기 과제인 것으로 나타났다. 결론: 실어증 중증도를 가장 잘 예측할 수 있는 요인을 분석한 결과 숫자 바로 따라지시하기 과제가 실어증 환자의전반적 언어 능력을 단시간에 효율적으로 평가할 수 있는 것으로 나타났다. 작업기억 과제 수행력은 자극 유형과 반응 순서에 따라 차이가 나타났다. 그러므로 실어증 환자의 언어손상과 관련된 작업기억을 적절하게 평가 및 중재하기 위해서는 작업기억 과제 유형 선택에 있어 신중한 고려가 필요하다.

Purpose: Researchers have argued that people with aphasia demonstrated working memory deficits and language processing impairments. The purposes of the current study were 1) to examine whether there are the task-specific effects on performance of working memory span measures, 2) to explore the relationship between working memory tasks and aphasia severity, and 3) to determine which working memory span tasks significantly predicted the aphasia severity of people with aphasia. Methods: Sixteen people with aphasia participated in this study. They were administered the Korean version of the Western Aphasia Battery and four types of working memory span tasks (digit forward, digit backward, word forward and word backward). We conducted analyses of variance, correlation coefficients and stepwise multiple linear regression analyses. Results: Individuals with aphasia performed significantly worse on word tasks compared to digit tasks and backward tasks compared to forward tasks. The significant two-way interaction between the modality and order are attributed to greater differences between the forward and backward modalities in digit span tasks than word span tasks. Aphasia severity correlated significantly with the scores of digit forward and backward span tasks but not with word span tasks. The regressions analysis revealed that only digit forward span tasks significantly predicted aphasia quotient. Conclusions: The results of the present study suggested that the performance of working memory tasks varies depending on task modality and response order. Furthermore, the digit forward span task served as the only significant predictor for aphasia severity. These results indicated that task-specific performance on working memory tasks needs to be taken into consideration to evaluate working memory deficits in aphasia.

연구목적: 신뢰라는 용어는 공급망 관리에서 가장 중시되는 개념이며 공급업자 관리부문에서 가장 자주 언급되는 표현 중 하나이다. 수출입거래에 있어서도 기업간 신뢰 관계형성이 매우 중요한 데, 본 연구에서는 사례연구 방식을 통해 기업 간 신뢰를 형성하는 요인, 특히 담당자 간의 신뢰가 수출입기업의 성과에 어떤 영향을 미치는지를 분석하고자 한다. 논문구성/논리: 이를 위해 수출회사와 수입회사의 담당자 간의 신뢰에 초점을 두되, 주로 수입회사 담당자와의 인터뷰와 수입회사 실적데이터를 분석하여 시기적으로 담당자 간의 신뢰의 정도를 정의하는 한편 그 신뢰의 정도에 따라 사업성과가 어떻게 변화하였는지 관련성을 분석하였다. 나아가 수입회사의 인력 중 수출회사 담당자와 직접 커뮤니케이션을 수행하는 구매/영업/ 마케팅 담당자 및 경영진과의 면접조사를 진행하여 신뢰의 중요성 및 그에 따른 경영성과를 구체적으로 분석하였다. 결과: 수출입 담당 실무자 간의 관계악화 및 신뢰도 저하로 인해 양사의 거래규모는 지속적인 하락세를 보이고, A社는 B社를 대체할 수 있는 타사를 지속적으로 물색하며, 결별 시기를 저울질하고 있고, B사 또한 직접 진출한 자회사가 제대로 한국 시장에 적응하면 언제라도 A社와의 거래관계를 종료할 것으로 보여진다. 독창성/가치: 본 사례연구를 통해 기업 전반 또는 최고 경영진 간의 신뢰 못지않게 실무 담당자 간의 신뢰도 또한 수출입 성과에 중요한 영향을 미칠 수 있음이 확인되었다. 특히 회사의 최고 경영진 간의 신뢰와 파트너십에 전혀 문제가 없었음에도 불구하고, 실무 담당자 간의 신뢰 훼손이 결정적 성과 악화 요인이 될 수 있음이 확인된 점도 의의가 크다.

Purpose: Trust is the most important concept in supply chain management and one of the most frequently mentioned expressions in supplier management. Development of trust-based relationships between companies is also crucial in import and export transactions. Therefore, this study was conducted to analyze the factors that develop trust between companies, especially between managers, through a specific case. Composition/Logic: Interviews with the importing company representatives, its performance data, and the degree of trust between its annual representatives were analyzed, as was the relevance of how business performance changed with changes in the degree of trust. In addition, interviews were conducted with the purchasing/sales/marketing personnel and management in direct communication with export company personnel to analyze the importance of trust and its impact on management performance. Findings: It was observed that the transaction volume of the two companies that were studied has continued to decline due to worsening trust between working-level officials in charge of exports and imports. The study found that the Korean importer(Company A) has been making efforts to end the business relationship by continuously searching for a new supplier to replace the existing trader(Company B), while the exporter(Company B) is also expected to end its relationship with Company A at once if its own subsidiary company successfully adapts to the Korean market. Originality/Value: This study confirmed that trust among practitioners, as well as across enterprises or the top management can have a significant impact on import-export performance. In particular, the finding that undermining trust among working-level officials can be a decisive factor in worsening performance, even if there are no problems related to trust and partnership among the company’s top executives, is also significant.

This paper presents thermodynamic performance analysis of organic Rankine cycle (ORC) using low temperature heat source in the form of sensible energy and using liquefied natural gas (LNG) as heat sink to recover the cryogenic energy of LNG. LNG is able to condense the working fluid at a very low condensing temperature in a heat exchanger, which leads to an increased power output. Based on the mathematical model, a parametric analysis is conducted to examine the effects of eight different working fluids, the turbine inlet pressure and the condensation temperature on the system performance. The results indicate that the thermodynamic performance of ORC such as net work production or thermal efficiency can be significantly improved by the LNG cold energy.

배경 및 목적: 인공와우 이식 아동의 수술 후 언어능력에 관한 개인차를 설명할 수 있는 근본적 기제에 관한 관심이 대두되고 있다. 이 중, 작업기억용량은 언어정보 유지 및 처리와 관련하여 다양하게 연구되어 왔다. 본 연구에서는 인공와우 이식 아동의 수술 후 언어능력에 있어서 언어․인지적 근본기제로서 작업기억용량이 미치는 영향에 대해 살펴보고자 하였다. 방법: 선천성 농 혹은 고심도 청각장애로 인공와우 이식 수술을 받은 7∼9세 아동 20명을 대상으로 하였다. 언어능력은 표준화된 검사인 『수용․표현 어휘력 검사』 및 『구문의미이해력 검사』로 평가하였고, 작업기억용량은 단어 바로 및 거꾸로 지시하기 과제로 측정하였으며 두 과제의 평균을 작업기억용량의 지표로 사용하였다. 인공와우 이식 수술연령과 인공와우 사용기간, 생활연령, 그리고 작업기억용량 중에서 수용어휘력과 구문이해력을 유의하게 예측하는 변수를 단계적 중다회기분석을 통해 알아보았다. 그리고 작업기억용량에 따라 두 집단으로 구분하여 인공와우 이식 수술연령 및 인공와우 사용기간, 그리고 생활연령을 통제하였을 때 수용어휘력과 구문이해력간의 차이를 살펴보았다. 결과: 단계적 중다회기분석 결과, 인공와우 이식 수술연령, 인공와우 사용기간, 생활연령, 작업기억용량 중에서 수용어휘력과 구문이해력을 유의하게 예측하는 변수는 작업기억용량인 것으로 나타났다. 인공와우 이식 수술연령 및 인공와우 사용기간과 생활연령을 통제하였을 때 작업기억용량에 따라 수용어휘력과 구문이해력 간의 차이가 유의미한 것으로 나타났다. 즉, 작업기억용량이 높은 집단이 구문이해력에서 작업기억용량이 낮은 집단에 비해 유의하게 수행력이 향상되었으나 수용어휘력에서 집단 간 수행력의 차이는 크지 않은 것으로 나타났다. 논의 및 결론: 작업기억용량이 인공와우 이식 수술연령, 인공와우 사용기간, 생활연령 변수에 비해 수용어휘력과 구문이해력을 유의미하게 예측하였으며, 작업기억용량이 높은 집단이 낮은 집단에 비해 구문이해력에서 높은 수행력을 보이는 것으로 나타났다. 즉, 이러한 결과는 작업기억용량이 다른 변수에 비해 언어능력에 기여도가 높은 변수이며, 언어처리부담이 높은 구문이해력에서 나타나는 개인차를 설명할 수 있는 근본기제로 작용하고 있음을 시사한다.

Background & Objectives: Working memory capacity (WMC) has received considerable attention as an underlying cognitive mechanism that may account for individual differences in language skills in children with cochlear implants. The purpose of the current study was to investigate which variable significantly predicted differences in performance on a receptive vocabulary test and a sentence comprehension task among age of the cochlear implant, chronological age, duration of usage of cochlear implant, and WMC. In addition, the study examined whether there were significant differences between high and low WMC groups in the two language tests when the age of the cochlear implant, duration of usage of cochlear implant, and chronological age were statistically controlled. Methods: Twenty prelingual and congenital deaf children between the ages of 7 and 9 years, who received cochlear implantation, participated in the study. The language skills were assessed using standardized tests such as the Receptive and Expressive Vocabulary Test (REVT) and Korean Oral Syntax Expression Comprehension Test (KOSECT). WMC was measured using word forward/backward pointing span tasks. The average of the results of the two span tasks was used as an index of WMC. Results: The results from the stepwise multiple regression analyses revealed that the WMC was a significant predictor of score on both language tests. The results of ANCOVA showed that the high WMC group showed significantly better performance on the KOSECT than the low WMC group, whereas the group differences were negligible in the REVT. Discussion & Conclusion: The current results suggested that WMC serves as an underlying cognitive mechanism responsible for individual differences in language performance in children with cochlear implants. The effects of WMC emerged more evidently in a test with greater cognitive load such as a syntactic comprehension test compared to the receptive vocabulary test, given that the high and low WMC group differences were the greatest in the sentence comprehension test.

오늘날 디지털화된 기업환경은 과거의 경영방식에서 벗어난 새로운 형태의 능동적이고 신속한 경영활동을 요구하고 있다. 이는 고객의 다양한 니즈와 변화에 정확하고 신속하게 인지하고 대응하는 기업의 내적 역량과 깊은 관련이 있다. 특히 중소기업의 내적 역량의 강화는 중견기업, 대기업으로 성장하는 발판이 될 수 있다. 오늘날 기업의 내적 역량 향상 및 경쟁력 향상을 위한 요소중 하나로 기업의 정보화 역량이 주목받고 있다. 본 연구는 중소기업의 성공적인 정보화 구현에 필요한 업무환경에 관해 고찰하고, 정보화 업무환경을 구성하는 요인별로 기업성과에 미치는 효과를 검증하였다. 또한 제조업과 비제조업간의 정보화 업무환경의 차이를 살펴보았다. 본 연구는 종속변수인 BSC기업성과에 영향을 미치는 선행 변수로 정보시스템 구축 활용과 업무프로세스 효율성을 제시하였으며, 정보시스템 구축 활용에 영향을 미치는 선행 변수로 정보화 업무환경의 4가지 요인 — 정보화 추진체계, 정보시스템 유지보수, 정보화 업무혁신, 정보화 인력 -을 제시하였다. 본 연구에서는 중소벤처기업부와 중소기업기술정보진흥원에서 2017년 12월 11일부터 2018년 1월 19일까지 3.700개 중소기업을 대상으로 수행한 ‘2017년 중소기업 정보화수준 조사’에서 수집한 설문 데이터를 활용하여 연구모델 설계 및 통계적 검증을 수행하였다. 분석 결과에 따르면 정보화 업무환경의 4가지 요인은 모두 정보시스템 구축 활용에 통계적으로 유의한 정의 영향을 미쳤으며, 정보시스템 구축 활용은 업무프로세스 효율성과 BSC기업성과에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 업무프로세스 효율성은 BSC기업성과에 통계적으로 유의한 정의 영향을 미쳤으며, 정보시스템 구축 활용과 업무프로세스 효율성은 연구모델안에서 매개변수 역할을 하였다. 기업유형에 따른 조절효과 분석을 수행하여 중소기업의 정보화 추진 환경에 대한 논의를 더욱 구체적으로 제시하였다.

This study examines the impact of information systems based working environment of SMEs on firm performance from the perspectives of Resourced-Based View and Endogenous Growth Theories. In addition, the difference between the manufacturing industry group and the non - manufacturing industry group was discussed in terms of the process of leading to the firm performance under the information systems based working environment. In this study, the research model was analyzed using the data of ‘Small and Medium Enterprise IT Information Quality Survey’ conducted from December 11, 2017 to January 19, 2018 at the Ministry of SMEs and startups and TIPA(Korea Technology & Information Promotion Agency for SMEs). The sample used in this study is 3,700 SMEs with ‘fewer than 300 regular employees’, of which 2,073 are manufacturing and 1,627 are non-manufacturing companies. This study suggests the utilization of information system(sales and purchasing system) and business process efficiency as the leading variables influencing the BSC firm performance. According to the results of analysis, four variables of IT environment (Informatization Implementation System, Information System Maintenance, Business Process Rebuild, Information Technology Human Resource) have statistically significant impacts on the utilization of information system, and utilization of information system has a statistically significant effect on business process efficiency and BSC firm performance. Business process efficiency has a statistically significant effect on BSC firm performance. Utilization of information system and business process efficiency have played mediating roles in the research model. In addition, we analyzed the moderating effects of the types of companies that divided the manufacturing and non - manufacturing sectors and suggested the discussions about information systems based working environment of SMEs more specifically.

Purpose: The purpose of this study was to identify the effects of infection control performance, infection control fatigue, and social support on the burnout of nurses working at National Safe Hospitals during the coronavirus disease (COVID-19) pandemic, and to use that data to suggest methods to reduce burnout among nurses. Methods: From June 30 to September 30, 2021, data were collected from 144 nurses who both consented to participate in the study and had worked for more than six months in National Safe Hospitals with 300 or more beds in the Gyeonggi-do Province in Korea. Data were analyzed using multiple regression analysis. Results: The factors affecting nurses' burnout at National Safe Hospitals during the COVID-19 pandemic were found to be infection control fatigue (β=.60, p<.001) and social support (β=-.27, p<.001). The explanatory power of these factors was 37.0%. Conclusion: Nurses' burnout at National Safe Hospitals was found to be at a moderate level. Burnout should be reduced through human, material, and administrative support, all of which can reduce infection-control fatigue. It is also necessary to develop both a non-face-to-face social-support-reinforcement program, considering restrictions mandated by infectious-disease pandemics, and a long-term intervention strategy to prevent burnout.

본 연구는 주 40시간 근무제(FWS)가 중소기업에 미치는 영향에 대하여 살펴본 것이다. 주요사항은 근로시간 단축으로 인한 직무환경의 새로운 변화 및 직무성과에는 어떤 영향을 주는지를 규명하고자 하였다. 이를 위하여 주 40시간 근무제를 도입한 경인지역 소재 중소제조업 10개사에 종사하는 직장인 427명으로부터 수집한 설문조사 결과를 바탕으로 실근로시간단축, 토요휴무제실시, 직무환경(업무강도, 여가생활, 교육훈련, 복리후생), 직무성과 등에 대한 실증분석을 하였다. 연구의 핵심인 주 40시간 근무제 도입에 따른 실근로시간의 단축과 토요휴무제의 실시가 조직 구성원의 직무환경과 직무성과에 미치는 영향과 관련된 가설을 검증한 결과는 선행연구물의 결과와 상당한 차이를 보였다. 즉, 대기업을 중심으로 살펴본 기존의 연구에서는 주 40시간 근무제의 실질적 효과가 실근로시간의 단축으로 나타난다고 했으나, 본 연구에서는 실근로시간의 단축이 직무환경에 오히려 부정적인 영향이 컸고, 직무성과에 미치는 효과는 없는 것으로 나타났다. 특히 실근로시간의 단축보다는 토요휴무제의 실시가 더 바람직한 영향을 미치는 것으로 나타나므로 중소기업의 경우에는 주 40시간 근무제 도입으로 실근로시간의 단축보다는 업체 사정에 맞는 토요휴무제를 운영하는 것이 더 중요하다는 것이다. 그러므로 중소기업은 내부 흡수력이 상대적으로 작고 대기업이나 금융기관의 근로자에 비해 생활이나 개인능력 등에서 상당한 차이가 있으므로 이를 무시하고 주 40시간근무제를 동일한 방식으로 도입하게 되면 기대되는 효과를 얻기보다는 오히려 급격한 단기적 비용 상승으로 심각한 부정적 결과를 초래할 가능성이 크다고 할 수 있다. 따라서 중소제조업에서 근로시간 단축이 성공적으로 정착되기 위해서는 생산성 향상과 근로시간 단축이 공존하는 방법을 정부와 기업, 근로자 및 현 사회가 함께 찾아가도록 해야할 것이다.

The purpose of this study is to identify how the 40-hour-a-week working system(FWS) affects small and medium enterprises(SME), and further discover what kind of environmental change the reduction of working hours brings about and how the reduction of working hours affect job performance. 427 employees from the 10 SME, specialized in manufacturing located at Gyeongin area, that introduced FWS. Then, the study conducted an empirical analysis of the reduction of actual working hours, work-free Saturday system, job environment(work intensity, leisure life, education and training, and welfare and employee benefits), and job performance based on the collected results. The actual status of the FWS of the SME can be described that work-free Saturday system is in vogue with the shortened working times. For SME, the results appeared far differently from almost all of the previous research outputs. The above results showed a significant difference from the previous studies conducted on the large companies or financial institutions. In the previous studies, many argue that the actual working hours need to be reduced for the FWS to show any practical improvements, but in this study, the reduction in the actual working hours rather had a negative impact on the job environment and showed little improvement in the job performance. In particular, the work-free Saturday appears to be far more important than the reduction in the actual working hours. This result is also quite different from the previous studies which argue for the reduction in the actual working hours, and it can be said that it is much more important for SME to adopt work-free Saturday than to reduce the actual working hours when they introduce FWS on the basis of their business conditions. Therefore, in order for the reduction in working hours to be successfully established in the SME, it is necessary for the government, the companies and the current society to seek a way for making the improvement in productivity and the reduction in working hours coexist and benefit each other.

본 연구는 커피전문점 서비스 종사원의 서비스 수행 시 셀프리더십은 직무만족과 직무성과에 매우 중요한 요소라 여겨지며, 커피업체의 효율적인 목표 달성을 위해 셀프리더십이 직무만족과 직무성과에 미치는 관계를 규명하고자 하였다. 종사원의 직무만족과 직무성과에 미치는 영향관계를 확인함으로써 인적서비스 의존도가 높은 커피 전문점의 경영에 효율적인 방안을 제시하고자 커피전문점 서비스 종사원을 대상으로 진행한 연구결과는 셀프리더십(행위 중심적 전략, 자연 보상적 전략, 건설적 사고전략)은 직무만족에 유의한 영향을 미치며, 직무성과에 유의한 영향을 미친다는 결론을 도출하였다. 연구결과를 바탕으로 커피전문점 서비스종사원의 셀프리더십은 직무만족, 직무성과와 같은 심리적인 지표에 영향을 미친다는 사실을 규명하였다. 따라서 커피전문점의 지속적인 발전과 경쟁우위를 위해서는 인적자원관리 차원에서 제도마련과 교육 및 훈련 등 전략적으로 접근하여 활용할 필요가 있으며, 우수사원 시상제도 및 휴가제도, 전문가를 통한 교육기회 제공 등은 큰 효과가 있을 것으로 사료된다.

When coffee shop service workers provide services, self-leadership is regarded to be one of the most crucial factors associated with job satisfaction and job performance.
