교수전문성 개발에 있어서 수업성찰이 중요함에도 불구하고 이에 대한 본격적인 연구가 없었다. 본 연구의 목적은 수업성찰의 이론적 토대가 되는 성찰의 개념, 절차 및 내용을 고찰하여 대학교수의 수업성찰 실천에 관한 시사점을 도출하는 것이다. 성찰의 개념은 Schön이 제시한 ‘행동 중 성찰’이며, 성찰의 절차와 내용은 Korthagen의 Core Reflection 모형을 통해 설명될 수 있다. Core Reflection 모형은 교수의 수행행동에 영향을 미치는 내면적 요인과 외현적 요인을 통합하도록 지원하며 교사 개인의 강점을 발전시키는 모형이다. 대학교수의 수업성찰 실천에 관한 시사점으로 첫째, 교수 개인은 수업 상황에서 지속적으로 자신의 행동을 관찰하고 성찰하면서 수업성찰 저널을 작성해야 한다. 둘째, 교수학습개발센타에서는 수업성찰의 내용과 절차에 관한 오리엔테이션 교육과 컨설팅을 제공해야 한다. 마지막으로 교수 개인의 성찰이 효과적이기 위해서 동료교수와의 수업나눔이 필요하다.

The purpose of this study is to draw implications about a practice of university faculty member's teaching reflection by considering the concept, process, and content of reflection as a theoretical basis of teaching reflection. The concept of reflection is based upon 'reflection-in-action' suggested by Schön, and the process and content of reflection is explained through Korthagen's Core Reflection model. The following three implications conclude: First, a faculty member should write a reflection journal by observing and reflecting consistently one's own behavior in a context of teaching. Second, the center for teaching and learning should provide an orientation and consultation about the content and process of teaching reflection. Finally, sharing lessons with the colleague faculty member is required to make an effective reflection for each faculty member.

시청자들은 지상파 방송 채널과 프로그램을 어떻게 이용하고 평가하고 있으며, 멀티 플랫폼 시대에 부합하는 지상파 방송의 위상 및 그에 걸맞은 역할과 책임에 관해 어떤 기대와 요구를 갖고 있는가? 이를 살펴보기 위해 일반 시청자에 대한 초점집단인터뷰를 실시했다. 주요 분석결과는 다음과 같다. 첫째, 시청자들의 채널 선택 및 프로그램 시청 행태는 라이프 스타일, 방송 시청을 위한 물리적 환경, 재방이나 다시보기를 통한 시청시간 및 공간의 선택성, 프로그램에 대한 충성도와 신뢰도, 인터넷이나 SNS 등의 이용 정도와 같은 요인들이 복합적으로 작용한 결과이다. 둘째, 공적 규제와 심의의 대상이라는 것은 지상파 방송에 대한 양가적 평가의 중요한 요인으로 작동하고 있다. 셋째, 개별 프로그램에 대한 만족도와 지상파 방송 채널에 대한 평가는 독립적으로 이루어지고 있다. 넷째, 다매체 다채널 환경에서 지상파 방송에 대한 시청자들의 기대와 욕구는 ‘핵심적 공론장’으로서의 역할 수행에 있으며, ‘좋은 방송’ 구현을 위한 중요한 평가 기준은 ‘신뢰도’이다. 다섯째, 국내에서 현재 실행되고 있는 질적 평가는 궁극적인 목적, 조사 설계와 방식 등에서 한계를 안고 있다. 좋은 방송 구현 및 시청자 주권 강화라는 목적과 가치를 바탕으로 지상파 방송의 신뢰도 제고를 위한 논의가 진행되어야 한다.

최근 대학에서는 교육기능이 강조되고 있으며 교육에 대한 학습자의 기대가 높아지는 추세이다. 그럼에도 불구하고는, 학습자의 기대와는 달리 대학 강의의 내용과 교수방식 등 강의 운영방식이 여전히 개별교수의 경험과 철학에 의존하고 있다고 지적된다. 이 같은 배 경 하에서 본 연구는 수요자인 학습자들이 강의내용과 강의방식에 대하여 어떻게 평가하고 있는지를 분석해 보고, 공급자인 대학과 교수들의 실제 강의 수행내용 및 수행방식과 수요 자인 학습자의 기대수준과의 괴리를 조정해 나갈 수 있는 정책적 시사점을 도출해 보고자 한다. 이를 위해 지방에 있는 ‘S' 대학교에서 시행중인 우수강의추천제도에서 제시된 우수강 의 추천내용을 네트워크 텍스트분석방법이라는 기법을 이용하여 그 핵심요소들을 도출하였 다. 우수강의 핵심요소의 차원은 여러 가지로 나타나는 다차원적 요소를 가지고 있는데 실 용적 지식, 학생참여, 피드백, 사례중심 등이 포함되는 것으로 분석되고 있다.

Recently, it is accepted that universities in Korea have put an emphasis on the function of teaching, rather than research, and students have also expected professors' teaching to meet their academic and job-related needs. Nevertheless, the reality is that in many cases, teaching in university has not met the expectations of students especially in terms of job market. In relation to the gap confronting universities in Korea, some endeavours have been made to bridge it, one of which is the evaluation system in which students are involved. The 'S' University located in the middle of Korea operates a teaching evaluation system in order to elevate the quality of teaching by professors. This artile utilizes the descriptive data, which were obtained by the evaluation system, to identify core elements relating to quality teaching. The analysis results show that hands-on knowledge, student participation, feedback, and case-oriented teaching are included in the core elements of quality teaching.

This study is to identify development strategies of local festival core programs and their influence to program reservation pattern with ascertaining the importance of local festival program, analyzing the service quality of local festival core programs and distinguishing the different results according to reservation pattern when visitors participate in the programs. As a result of factor analysis on service quality of festival program, the factors are reduced to 4 factors, and there were significant difference between the groups in variables except factor 2(physical factor) after the t-test on reservation pattern and when comparing the differences of overall average, the average of internet or telephone(cable) reservation group was much higher than on-site reservation group. In addition, when combined the results of regression analysis, which used dummy variable, it indicated that it was better to maximize the usage of internet or telephone(cable) reservation as on-site reservation had negative effect on overall satisfaction and behavioral intentions for revisiting or recommending the festival. Therefore, it is important to increase the reservation through internet or telephone to forecast the demand correctly and to prepare it efficiently. As these are the most important factors for the festival organizations which plan and manage the festival, they should find various strategies to activate internet or telephone reservation.

This study is for figuring out major components of construction quality infrastructure and suggesting improvement plan by benchmarking global best practice model and analyzing gap between the model and sample practice. Based on improvement plan, researcher could derive major characters and components of construction quality infrastructure, and also about the priority among core competency components of construction quality experts. The result showed that the 'human resource' was ranked the best priority followed by 'method' 'environment', 'equipment' among major characters and components of construction quality infrastructure. Also, for core competency components of construction quality experts, 'number of years in work places' was the best priority, and the 'professional knowledge on engineering' was another priority ranked. Far from general perception on competency components, 'academic education' ranked the last. It may allude that the current education system in this country is not effective in developing competency of quality engineers. In summary, this study shows professionalism of quality engineer is the most important thing in all the components.

The purpose of this study is to explore effective ways to improve core competencies for college students in future societies, and to enhance the quality of teaching in liberal arts subjects for competence. In doing so, the study examined the case of C university, which has made recent reforms to its competency-based liberal arts curriculum. The study reviewed the previous curriculum of liberal arts (2011-2018), the key reforms of the liberal arts curriculum, and the support given for liberal arts classes to improve their quality level. The findings are as follows; C university has lowered the maximum number of students from 80 to 60 in liberal arts classes for core competence. The university has also allowed absolute evaluation for its classes, so that students can participate actively and instructors can evaluate their student’s learning during the course. In addition, the university has assigned teaching assistants to eligible classes, and has provided them with additional evaluations in order to improve the quality of teaching. The results of this study would provide useful information to universities that have tried to build a competency-based curriculum system, and to improve the overall quality of instruction.

Background/Aims: The adenoma detection rate (ADR) does not reflect the complete detection of every adenoma during colonoscopy; thus, many surrogate indicators have been suggested. This study investigated whether the ADR and surrogate quality indicators reflect the adenoma miss rate (AMR) when performing qualified colonoscopy. Methods: We performed a prospective, multicenter, cross-sectional study of asymptomatic examinees aged 50 to 75 years who underwent back-to-back screening colonoscopies by eight endoscopists. The ADR and surrogate quality indicators, including polyp detection rate, total number of adenomas per colonoscopy, additional adenomas found after the ?rst adenoma per colonoscopy (ADR-Plus), and total number of adenomas per positive participant, were calculated for the prediction of AMR. Results: A total of 371 back-to-back colonoscopies were performed. There was a significant difference in ADRs (range, 44% to 75.4%; p=0.024), polyp detection rates (range, 56% to 86.9%; p=0.008) and adenomas per positive participants (range, 1.19 to 2.30; p=0.038), and a tendency of a difference in adenomas per colonoscopy (range, 0.62 to 1.31; p=0.051) and ADR-Plus (range, 0.13 to 0.70; p=0.054) among the endoscopists. The overall AMR was 20.1%, and AMRs were not different (range, 13.9 to 28.6; p>0.05) among the endoscopists. No quality indicators were significantly correlated with AMR. The number of adenomas found during the first colonoscopy was an independent factor for increased AMR (odds ratio, 1.79; p<0.001). Conclusions: The colonoscopy quality indicators were significantly different among high-ADR endoscopists, and none of the quality indicators reflected the AMR of good quality colonoscopy performances. The only factor influencing AMR was the number of adenomas detected during colonoscopy.

This research is to examine the relative impacts of relational benefits (social, confidential, and special treatment benefits) and core quality (core product and core service quality) on relationship satisfaction and relationship commitment (emotional, behavioral, and temporary commitment) in hotel and family restaurant context. In order to empirically investigate the proposed model, the data were collected from 300 respondents randomly selected from among the customer members who use the hotel and family restaurant if he or she agreed to participate in the survey. To test unidimensionality of the measures of each construct we employed scale refinement procedure. The results of reliability test with Cronbach's α, and confirmatory factor analysis warranted unidimensionality of the measures for each construct. In addition, convergent and discriminant validity of the measures was warranted from the result of comparisons of correlation analysis and measurement model analysis. The data were analyzed with structural equation modeling with LISREL 8.7W and SPSS Win/PC+ 12.0. The results and implications are follows: First, core quality had an effect on relationship satisfaction, but relational benefits did not have a significant effect on relationship satisfaction. Second, relational benefits had a positive effect on affective commitment, but core quality did not have a positive effect on emotional commitment. Third, relationship satisfaction had an effect on affective and temporary commitment, but did not have a significant effect on behavioural commitment. Finally, affective commitment had a positive effect on behavioral, and, in turn, increase temporal commitment. This study found what factors play in the process of developing commitment from the relational approach and the core service one. That is, the findings specify clearly the mechanism that customers use in understanding of organization-customer relationship in service industries. In this regard, this research was to meet the call of previous studies (eg., Iacobucci et al., 1994; Butcher, Sparks, and O'Callaghan, 2003), which suggest that marketing scholars should focus more on managerially relevant constructs that are associated with firm-customer interaction. The results suggest that both relational benefits and core quality concepts should be regarded as the core of relationship-oriented marketing concept and indispensable for gaining a short- and long-term relationship. The finding indicates that core service quality is still significant and substantial driver of customer satisfaction. It shows that improving core quality perceptions leads to higher satisfaction, and, ultimately to stronger commitment. In addition, relational benefits contribute to explain the relationship of firm-customer in service setting. This implies that relational benefits are well placed to provide managers with a useful predictive tool. This also provides insights with managers that customers who maintained a service relationship with a specific service employee are likely to be more loyal. In summary, the findings tell us somewhat about why the customer satisfied. In other words, this study explain that customer's decision for entering into and maintaining a long-term with service firm is driven by their assessment of the core quality and the relational benefits' aspects. Thus, the challenge facing service researchers is to investigate which factors influence the strength of the firm-customer relationship. The findings also are likely to support the Iacobucci et al.'s (1994) work, which explained overall satisfaction could be improved by either core quality or the friendly peripherals being good. It is also interesting to note that relationship satisfaction mediates the effect of core quality on the outcome variables such as affective, behavioral, and temporary commitment. These results imply that the development of relationships based on satisfaction and commitment (social approach) throu...

The injection molding is used in more than 70% of total production of plastic products. Weld line in injection molded part is one of the defects in injection molding process. Weld line deteriorates not only appearance quality but also mechanical property. In this study weld quality has been examined according to the injection processing temperature, materials and mold designs. We selected four different materials such as PA, PP, ABS and PS as experimental materials. Weld quality increased as injection processing temperature increases. It was more dependent on materials flow ability. As a result, weld quality incase of rectangular core is better than circular core.
