본 연구는 최근 건설현장에서 주목받고 있는 Building Information Modeling (BIM)의 효용성 분석에 초점을 맞추어 국내ㆍ외 20여 개 이상의 사례들을 분석하여 미래 활용방법 및 시사점을 분석한 논문이다. BIM은 현재까지 다양한 분야에서 활용되고 있으며 그 효과에 대한 가능성은 많은 선행 연구에서 찾아볼 수 있다. 그러나 그 구체적인 효용성에 대한 조사는 많이 이루어지고 있는 않은 상태이며 건설현장에서 예상되는 각종 인재 및 재해에 대한 대비책으로의 사용은 아직까지 미흡한 실정이다. 따라서 본 연구에서 기존의 사례들을 기반으로 향후 위기관리, 즉 건설 리스크에 BIM의 활용여부를 진단하여 보고 실제 연구결과를 중심으로 논의하고자 한다. 실제로 몇몇의 프로젝트들이 BIM을 활용하여 공기의 절감 효과를 보았으며 이는 결국 건설 시기에 대한 문제로 이어져 계절 변화에 따른 인적사고 및 자연재해로부터의 예방효과를 보았다.

The study is designed to elaborate the effectiveness of Building Information Modeling (BIM) in regard to its financial benefits and risk management. BIM has been widely analyzed by the previous literature, but its specific effectiveness has not been assessed and its utilization for risk management is at its infancy. Therefore, this study identifies barriers in conducting the BIM studies and articulates possible outcomes of the actual BIM-based construction project. Overall about 20 domestic and international projects are assessed and about 50 literature is reviewed to detail the benefits and risks of using BIM in real projects. It is found that BIM brings benefits in communication, time-saving and return-on-investments. In addition, some cases have reported that BIM creates positive aspects for risk management against human accidents and natural disasters in construction sites.

이 연구의 목적은 특성화전문대학육성(SCK)사업의 효과를 구명하는데 있었다. 이를 위해 특성화전문대학육성지원사업의 선정대학과 비선정대학의 특성을 구명하고, 성향점수매칭 (PSM)을 활용하여 재정지원사업이 전문대학의 교육성과에 미치는 영향을 구명하고, 이중차 분법(DID)을 활용하여 재정지원사업의 순수효과를 구명하였다. 주요 결과로는 전문대학들은 SCK사업을 통해 신입생 경쟁률, 중도 탈락률, 창업자 수, 취업률 측면에서 개선이 있었고, 특 히 사업 선정대학이 비선정대학에 비해 신입생 경쟁률 및 충원율 등에서 평균값 및 증가폭이 더 큰 것으로 확인되었다. 반면 성향점수매칭 결과는 단기적으로 신입생 및 재학생 충원율에, 장기적으로는 취업률에만 효과가 있는 것으로 나타났다. 그리고 시간적 요인을 제거하여도 신 입생 경쟁률 및 충원율에서 긍정적 효과를 보였다. 후속 연구를 위한 제언으로는 정부재정지 원사업의 효과성을 분석하기 위해 지속적이고 다양한 연구를 실시할 필요가 있다. 또한 대학 평판, 인지도 등과 같은 질적 측면을 고려한 효과성 분석이 이루어져야 하며, 재정지원사업의 다양한 효과를 확인하기 위해 대학정보공시 항목의 개선이 이루어질 필요가 있다.

The purpose of this study is to analyze the effect of the Specialized College of Korea(SCK) project. For this study, analyzing the characteristics of selected colleges in SCK projects, examined the educational performance of colleges using the Propensity Score Matching(PSM) and Difference-in-Differences(DID)method. Major study results showed that there were improvements in colleges in terms of college acceptance rate, dropout rate, number of start-up founders, and employment rate through the SCK project. Further analyzed these results by using PSM method, this project had a positive effect on enrollment rate of freshman and existing student in the short term and employment rate in the long term. Lastly, removed the temporal factor and found out that this project still had a positive effect in terms of college acceptance rate, enrollment rate of freshman. As suggestions for follow-up studies, it is necessary to conduct continuous and diverse studies to analyze the financial support project effectiveness. Next, the effectiveness of this project needs to be analyzed in consideration of qualitative aspects such as college reputation and awareness.

일반국도는 지역과 지역을 연결하는 간선도로 역할을 하는 도로이다. 일반국도는 통과교통 비중이 높아 약 90% 이상이 직진교통량이며, 좌회전 및 부도로의 교통량은 직진교통량에 비해 매우 낮다. 이러한 도로의 특성을 고려해 볼 때, 고정식제어보다는 감응제어가 더 효과적이다. 이와 같은 감응제어의 효과가 과거 많은 논문에서 검증되었음에도 우리나라의 경우 일부 도시구간에서 극히 한정적으로 사용하고 있을 뿐 본격적인 설치가 전혀 이루어지지 않았다. 그것은 우리나라의 국도 시설 특성 상 감응제어를 교과서적으로 운영하기 어려운 요소가 많다는 데에 있다. 본 연구에서는 감응제어 도입이 어려운 이유를 파악하여 우리나라 현실에 맞도록 개선하였으며, 시범운영을 통해 국도 감응제어시스템의 효과를 입증하였다.

A national highway takes on an arterial roadway role between regions. It's traffic volume of minor approach is very lower than mainline because most of the traffic of national highway consists of through traffic. This means an actuated signal operation is more efficient on the national highway than pre-timed signal. actuated signals have detections on some or all movements except the mainline. In spite of these effects have been evaluated in previous studies, widespread propagation of actuated signal operation has not made so much in Korea. Because there are so many problems to use actuated signal as it is in side of roadway facilities. In this study, improved a actuation system for the national highway and evaluated it with field implementation.

Purpose To test the impact of interpersonal caring theory empirically on six major psychosocial functioning outcomes of persons with serious mental illness. Methods This was a quasi-experimental pre- and post-test design with data collection from a total of 266 patients with long-term serious mental illness, who were diagnosed with schizophrenia spectrum disorder and followed at 6-month intervals over a 24-month period in three groups: a community psychiatric service group, a community service with interpersonal caring intervention group, and a control group. Three hypotheses between the intensity, specificity, and longitudinality of services were tested using growth curve analysis. Results Hierarchical linear modeling supported associations of hypotheses between the intensity, specificity, and longitudinality of services and improved patient outcomes. Conclusion This study suggests that the intensity, specificity, and longitudinality of interpersonal caring interventions in community psychiatric service programs deserve attention in order to improve and maintain patient functional outcomes.

Purpose: The purpose of this study was to test a predictive model that could predict and explain work effectiveness among staff nurses at local hospitals. Methods: Between April 1 and May 15, 2009, 340 nurses were recruited from two hospitals (one in Ulsan and one in Yangsan). Data were collected via self-administered questionnaires and analyzed using structural equation modeling. Results: A modified model was retained, as the final path model showed a very good fit with the data. Job characteristics and compensation justice were found to have direct and positive effects on empowerment. Job characteristics, transformational leadership, and empowerment were found to directly and positively affect work effectiveness. In addition, job characteristics were found to have a greater effect on empowerment and work effectiveness than other factors do. Conclusion: This structural equation model was used to test the relationships between these factors and work effectiveness. Empowerment mediated the relationship between job characteristics, transformational leadership, and work effectiveness. Findings from this study can be used to design the strategies for increasing work effectiveness in Korean nurses.

This study aimed to verify the effectiveness of Family Participation Intervention (FPI) for children with Autism Spectrum Disorders (ASD) by integrating and comparing effect sizes of single-subject studies published in Republic of Korea between 2000 and 2021. For this purpose, twenty-seven dissertations and journals were selected based on predefined criteria and were analyzed. Effect sizes were calculated according to various variables such as treatment approach, goals, subject group charac teristics, and session characteristics using a random effects model. The results are as follows. First, the overall effect size of FPI for children with ASD was Tau-U .88, indicating a medium effect. Additionally, the effect size for the maintenance phase was Tau-U .95, indicating a large effect. Second, this study found that for elementary school students, using a community-cen tered or play (activity)-centered approach with the goal of improving adaptive behavior, involving various family members, conducting at least 20 sessions, showed better effects than other condition. This study is meaningful in that it verifies the ef fectiveness and validity of FPI for children with ASD. Additionally, it provides detailed information on the factors improving the intervention effectiveness.

Purpose: Advanced schistosomiasis, the most severe stage of Schistosoma japonicum infection, profoundlyimpairs patients’ quality of life (QoL) and increases vulnerability to anxiety and depression. Since 2004, China has launched a medical assistance program for the patients with access to medicaland/or surgical treatment, in which health workers have incorporated nursing interventions to addressthese challenges. This meta-analysis evaluated the effects of nursing interventions on QoL, anxiety,depression, and complications in advanced schistosomiasis patients. Methods: Seven databases [PubMed, Web of Science, the Cochrane Library, China Biology Medicine, ChinaNational Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang] weresystematically searched for randomized controlled trials up to August 1, 2024. Data were analyzed usingReview Manager 5.4 (Cochrane Collaboration) and R 4.2.3 (R Project, a free, open-source language andenvironment primarily used for statistical computing and graphics). Outcomes included QoL (WorldHealth Organization Quality of Life Brief scale and Karnofsky performance status), anxiety (Self-ratingAnxiety Scale), depression (Self-rating Depression Scale), and complications. The protocol was previouslyregistered with the International Prospective Register of Systematic Reviews (CRD42023406707). Results: A total of 23 studies with 2232 patients were included. Nursing interventions improved QoL withgreater benefits observed in longer intervention periods. Anxiety (standardized mean difference: -1.52,95% confidence interval (CI): -2.10 to ?? 0.94) and depression (standardized mean difference: -1.13, 95% CI:-1.43 to ?? 0.84) scores were markedly reduced. The risk of complications decreased by 64% (relative risk:0.36, 95% CI: 0.27 to 0.48). Subgroup analyses highlighted age as a key modifier of intervention efficacy. Conclusion: Nursing interventions effectively enhance QoL, alleviate psychological distress, and reducecomplications in advanced schistosomiasis patients. These findings advocate for integrating structurednursing protocols into China’s national healthcare programs and global schistosomiasis managementstrategies.

Objective: To evaluate the effectiveness of the National Health Screening Program for Infants and Children (NHSPIC) in the early diagnosis of neurodevelopmental disorders (NDDs) utilizing data from the National Health Insurance Database of South Korea.Methods: We enrolled children born between 2011 and 2018 who completed the first to fourth stages of the NHSPIC. A positive finding was defined as a recommendation for further evaluation during one or more stages. Participants were categorized into the positive and negative finding groups. Following 1:1 propensity score matching, 82,138 participants were assigned to each group.Results: Comparative analysis revealed that participants with positive findings exhibited a higher risk of developing all seven NDDs, particularly for autism spectrum disorder (hazard ratio [HR], 19.70; 95% confidence interval [CI], 17.48?22.20), intellectual disability (HR, 17.11; 95% CI, 14.69?19.93), developmental language disorder (HR, 11.74; 95% CI, 10.73? 12.84), and cerebral palsy (HR, 11.34; 95% CI, 8.67?14.84). The HR for learning disability was 4.31 (95% CI, 2.94?6.34), whereas attention-deficit hyperactivity disorder had an HR of 3.57 (95% CI, 3.37?3.78). Tic disorder had the lowest HR (HR, 1.64; 95% CI, 1.48?1.82). Additionally, HRs were calculated for each NHSPIC stage, demonstrating the utility of specific stages in the early detection of each NDD.Conclusion: Developmental screening tests in the NHSPIC contributed to the early diagnosis of NDDs. This study underscores the significance of the NHSPIC and provides foundational evidence to inform and enhance policies related to child health screenings.

To determine the effect of inspiratory muscle training (IMT) on pulmonary function, respiratory muscle strength (RMS), and functional capacity in patients undergoing cardiac surgery. The PubMed, PEDro, CINAHL, Web of Science, CENTRAL, and EMBASE databases were searched from inception to June 2020. Randomized controlled trials (RCTs) that evaluated patients who underwent cardiac surgery were included in this review. Meta-analysis performed using a random-effects model showed that the mean difference in forced vital capacity, forced expiratory volume in 1 second, 6-minute walk distance, and RMS was 3.47% (95% confidence interval [CI], 0.57 to 6.36), 5.80% (95% CI, 2.03 to 9.56), 78.05 m (95% CI, 60.92 to 95.18), and 4.8 cmH2O (95% CI, -4.00 to 13.4), respectively. There is strong evidence that IMT improves inspiratory muscle strength, pulmonary function, and functional capacity, and reduces the length of hospital stay in patients undergoing cardiac surgery.

Purpose: Evidence on non-pharmacological interventions for adolescents with type 1 diabetes is unclear. This review aimed to evaluate the effectiveness of non-pharmacological intervention in adolescents with type 1 diabetes. Methods: We conducted a search on databases from November 11 to 19, 2022, for randomized controlled trials for the effects of non-pharmacological intervention in adolescents with type 1 diabetes. To identify recent research trends, we included studies published from 2017 to November 2022. The risk of bias was assessed using the Cochrane risk-of-bias tool 2.0. To estimate the effect size, a meta-analysis was performed using RevMan 5.4 program and R Studio. Results: A total of 45 studies were included in the systematic review. Among those, 30 studies were included in the meta-analysis. Non-pharmacological interventions were significantly effective in improving Glycated hemoglobin (HbA1c) (standardized mean difference [SMD] = -0.26, 95% confidence interval [CI]: -0.42, -0.09), quality of life (SMD = 0.44, 95% CI: 0.13 to 0.76), and anxiety (SMD = -0.91, 95% CI: -1.26, -0.56). Subgroup analysis showed that duration of intervention was not a covariate related to HbA1c levels. Conclusions: Non-pharmacological interventions have shown effectiveness in improving the HbA1c, quality of life, and anxiety in adolescents with type 1 diabetes. Future studies with more rigorous methodology are needed to confirm and strengthen the validity of these findings. Additionally, attention to changes in the lipid profile and self-care motivation among adolescents with type 1 diabetes is warranted.

Purpose: This systematic review aimed to investigate the effectiveness of home visiting programs targeting parents who have maltreated their children on the prevention of child maltreatment recurrence. Methods: Major databases were searched (Ovid-Medline, PubMed, Cochrane Library, CINAHL, and RISS). The frequency of maltreatment was measured for the meta-analysis, which was conducted using Review Manager 5.2 software. The effect size was measured using odds ratios (ORs). Results: Six studies were included in the analysis, none of which were conducted in South Korea. The meta-analysis demonstrated that the risk of child maltreatment recurrence significantly decreased after a home visiting program was implemented (OR=0.45, 95% confidence interval [CI]=0.29-0.68). Nurses were the most common intervention providers. Conclusion: Home visiting programs should be provided for families in which maltreatment has already occurred to prevent the recurrence of maltreatment and foster a home environment in which children can live safely. Since the rate of child maltreatment in Korea is increasing, further research is needed to develop and implement home visiting programs in which nurses play a major role in preventing the recurrence of child maltreatment.

본 연구는 문헌연구를 통하여 먼저 세계 주요 국가들의 경찰항공대의 현황과 장비 등에 대해 살펴본 후, 무인항공시스템을 경찰항공대에 도입·활용하는 것에 대해서 미국의 사례 분석을 중심으로 비용효과분석(Cost-Effectiveness Analysis)의 측면에서 타당성을 검토해 보았다. 단위비행시간을 분석단위로 하여 추산한 결과, 경찰헬기는 노후화에 따른 감가상 가비(depreciation cost), 연료비(fuel cost), 관리비(maintenance cost)가 매우 큰 반면, 무인 항공시스템은 시간 당 운영비가 헬기의 10퍼센트에서 40퍼센트에 지나지 않는 것으로 분 석되었다. 경찰항공대에서 무인항공시스템이 활용된다면 관리주체가 명확해 지고, 타항공 기의 운항 일정을 알 수 있기 때문에 충돌가능성도 줄일 수 있는 등 여러 장점이 있다. 특히, 경찰 헬기가 비행할 수 없는 지역이나 테러나 인질 상황 등으로 피격·추락의 위험이 있는 곳에 무인항공시스템을 상호보완적으로 운영한다면 엄청난 시너지 효과를 얻을 수 있을 것으로 예상된다.

This study firstly looked at the mission and profile of the major police aviation units around the world and then reviewed the case study of a cost-effectiveness and feasibility analysis of implementing Unmanned Aerial Systems(UAS) into the police helicopter fleet in Los Angeles Police Department. The case study showed that the operating cost of the UAS is just 10 – 40 percent of that of helicopter fleet per every flight hour. The reason is that depreciation, fuel, and maintenance costs of helicopters are very expensive. If the police aviation unit employs UAS, the police accountability of using UAS will be clearer and the possibility of collision with other air crafts can be decreased. Furthermore, the synergy effect will be gained if the UAS is complimentarily applied to a hostage, terror, or any situation where the police helicopter cannot operate the mission due to limitation. The possibility and methods of implementing UAS in the Korean National Police helicopter fleets are discussed.

The purpose of this analytic study is to design and examine an efficient hydrogen liquefaction cycle by using a pre-cooler. The liquefaction cycle is primarily comprised of a pre-cooler and a refrigerator. The fed hydrogen gas is cooled down from ambient temperature (300 K) to the pre-cooling coolant temperature (either 77 K or 120 K approximately) through the pre-cooler. There are two pre-cooling methods: a single pre-coolant pre-cooler and a cascade pre-cooler which uses two levels of pre-coolants. After heat exchanging with the pre-cooler, the hydrogen gas is further cooled and finally liquefied through the refrigerator. The working fluids of the potential pre-cooling cycle are selected as liquid nitrogen and liquefied natural gas. A commercial software Aspen HYSYS is utilized to perform the numerical simulation of the proposed liquefaction cycle. Efficiency is compared with respect to the various conditions of the heat exchanging part of the pre-cooler. The analysis results show that the cascade method is more efficient, and the heat exchanging part of the pre-coolers should have specific UA ratios to maximize both spatial and energy efficiencies. This paper presents the quantitative performance of the pre-cooler in the hydrogen liquefaction cycle in detail, which shall be useful for designing an energy-efficient liquefaction system.

배경: 당뇨병 환자에게 관상동맥심질환은 생존률, 건강 상태 유지 및 삶의 질에 주요한 영향을 미치는 합병증이며 적극적인 당뇨병 치료는 이러한 심혈관 합병증을 예방할 수 있으나 당뇨병의 적극적 치료와 관리에는 많은 비용이 소요된다. 목적: 제2형 당뇨병 환자를 대상으로 메트포르민과 글리메피리드 병합요법과 메트포르민과 피오글리타존 병합요법의 비용-효과성을 비교하고자 하였다. 연구방법: 마르코프 코호트 프로세스(Markov Cohort Process Model) 모형을 이용하여 비용-효과분석을 실시하였다. 연장된 수명 (life years gained, LYG)과 삶의 질(quality)을 보정하여 증가된 QALYs를 주요 효과 지표로 측정하였고, 총비용으로는 직접의료비용과, 환자와 가족의 교통비를 직접비의료비용으로 고려하였고 환자와 가족의 시간비용을 간접비용으로 포함하였다. 연구결과: 비용-효과분석 결과, 메트포르민과 글리메피리드 병합요법의 경우 총 비용은 5,962,288원, 효과는 7.94LYG, 6.43QALY이었다. 반면 메트포르민과 피오글리타존 병합요법은 총 비용 10,982,243원, 효과 8.62LYG, 6.99QALY으로, 점증적 비용-효과비(ICER)는 7,402,663원/LYG과 8,934,546원/QALY 이었다. 결론: 우리 사회의 연장된 수명(LYG)에 따른 지불의사가 700만원 이하인 경우는 메트포르민과 글리메피리드 병합요법이 비용-효과적인 대안이며 700만원 이상인 경우에는 메트포르민과 피오글리타존 병합요법이 비용-효과적인 대안이 될 수 있다.

This study seeks to draw policy implications for the future by analyzing the effectiveness of the MB government's comprehensive 6·3 policy aimed at reducing private education expenses using a Likert-type 5-point scale. The area of policies designed to provide alternatives to private education received the highest effectiveness rating of 3.52. The area of policies focused on improving oversight of private educational institutions scored 3.29. Policies aimed at establishing institutional and cultural support for reducing private education costs scored 3.20, and area of Internalization of public education scored 3.12, Improvement of the entrance examination system scored 3.08. Five policies were highly rated, with scores of 3.5 or higher : improving EBS SAT lecture services (3.60), and increasing transparency in academy management (3.60), enhancing after-school educational services (3.53), improving English education quality (3.51). The remaining policies was between ratings of 2.71 and 3.50. In the period following the implementation of these policies, private education costs, which had previously been rising sharply, began to stabilize or decrease due to government intervention. However, when subsequent administrations reduced focus on this issue, private education expenses once again began to climb. This suggests that while the policies were effective in the short term, they lacked adequate long-term management and sustainability. Therefore, it is recommended that future efforts to reduce private education costs be integrated into a broader, long-term educational vision for Korea, rather than treated as a standalone policy.

Digital Transformation (DX) is the primary innovation strategy to enhance organizational flexibility and productivity in the workplace. Each company promotes DX within its unique organizational direction and situations, and employee competency becomes a critical factor for successful transformation. However, existing small and medium-sized enterprises (SMEs) have limited resources to hire AI experts or develop appropriate DX implementation strategies compared to large enterprises. As a result, many SMEs adopt a more practical and efficient approach by implementing internal AI reskilling programs for their employees. In this paper, we aim to examine whether such reskilling programs effectively drive DX adaptation within SMEs. For our investigation, we designed AI-based reskilling programs that were implemented across 39 SMEs from diverse industries, alongside Proof of Concept (PoC) projects that were aligned with each company’s DX goals. We extracted key terms from the reskilling program reports and categorized the companies by industry type and organizational scale. We also conducted text analysis to identify strategic directions and transformation intents regarding DX. Our findings demonstrated that AI reskilling programs could effectively support SMEs in achieving DX. Our analysis results also highlight how industry-specific characteristics, and the availability of internal resources influence DX implementation. In particular, the number of employees and the ratio of R&D investment emerged as key factors. Furthermore, this study provides a practical roadmap for AI adoption and strategy tailored to similar types of SMEs, serving as a foundational reference for inclusive and sustainable digital transformation.

시한성 표적(Time Sensitive Target : TST)이란 신속하게 움직이기 때문에 대응 가능시간이 제한되는 표적을 의미한다. 시한성 표적은 1991년 걸프전에서 이라크의 스커드 미사일 위협 이후 군사적으로 큰 고려사항이 되어왔다. 그 이후, 제한된 시간 안에서 시한성 표적을 효과적으로 공격하기 위한 여러 방법들이 연구되어 왔다. 시한성 표적 공격 작전에는 감시자산, 지휘통제 시스템, 공격자산 등의 다양한 수단들이 필요하며 이 수단들의 효율적인 협력이 중요하다. 본 논문에서는 모델링 및 시뮬레이션(M&S) 방법을 사용하여 시한성 표적 작전에 투입되는 자산들의 효율성을 분석하였다. 이 연구를 통하여, 시한성 표적에 성공적으로 대응할 수 있도록 투입 자산들의 효율성을 비교할 수 있는 방안을 제안하였다.

A time-sensitive target(TST) is a target that requires an immediate response because its vulnerability window is very limited like a fast-moving mobile target. TSTs have been a major concern of the military since SCUD missile threats in Operation Desert Storm in 1991. The military community has sought effective ways to destroy these targets within their vulnerability window. A TST operation requires a variety of assets such as a sensor, command & control, and a shooter to be engaged and working together in a timely manner. In this paper, we evaluate the effectiveness of the assets involved in a TST operation using the modeling and simulation method. The results can provide the military community with insights about ways to utilize TST assets to maximize the possibility of destroying TSTs.
