PURPOSES : This study sought ways to connect urban above ground roads and underground roads to utilize urban space more efficiently in the development of underground roads, which are currently under development in order to alleviate problems caused by oversaturated above-ground roads. A simulation analysis was performed to develop an operation strategy that connects above-ground and underground roads to prevent congestion in above-ground areas such as entrances and exits from transferring to underground roads as well as to present its effectiveness. METHODS : Traffic efficiency analysis according to the operation strategy of above ground and underground roads was conducted using VISSIM, a microscopic traffic simulation software. The functions implemented in VISSIM were collected to set effectiveness analysis indicators for each underground road operation strategy. The Shinwol-Yeoui Underground Road was selected as the spatial scope of this study, and a surrounding road network was constructed. In addition, full-scale simulation analysis preparations were completed by performing network calibration based on the actual traffic attribute data of underground and surrounding surface roads within the construction scope. Accordingly, a traffic efficiency evaluation analysis was conducted based on the underground road operation strategy. CONCLUSIONS : Information on the increase in traffic volume within the Shinwol-Yeoui underpass was collected every 15 min. The analysis was divided into an analysis of the traffic situation within the underpass through demand control when the service level reached level D and an analysis of when demand control was not performed. It was found that demand control was necessary for the Shinwol-Yeoui Underpass when the internal traffic volume reached 2,500 vehicles/h. In addition, to analyze the spread of traffic and congestion owing to the weaving phenomenon caused by lane changes in the underpass, an analysis was conducted to observe the traffic improvement effect when full lane changes are possible for the Shinwol-Yeoui Underground Road, which currently has some lane-change-permitted sections. The analysis showed that both the maximum traffic volume and average travel speed showed better results when lane changes were allowed, and the communication situation at Yeoui JCT was found optimal.

OK 렌즈를 착용한 환자들은 안압, 각막 내피 세포 수 및 중심 각막 두께에서 기준값 대비 유의한 변화가 없었다 (p>0.050). 결론 : 안경 대비 각막교정렌즈가 구면 등가 구면굴절력(SE)를 감소시키고 시력을 향상시켰으며, 안축 연장을 늦추는데 더 효과적임을 알 수 있었다.

The objective of this study was to conduct research and analysis using Group Focus Interview to survey the between construction site workers and managers implementing for the Severe Accident Punishment Act. Focused on measures to improve safety management effectiveness for the effectiveness of establishing a safety management system. A plan to improve the efficient safety management system was presented to 50 construction industrial managers and workers. In order to ensure the industrial accident prevention policies appropriately, it is necessary to be aware of safety obligations for workers as well as business operators. In addition, despite the existence of a commentary on the Serious Accident Punishment Act, confusion in the field still persists, so in the event of a major accidents, the obligation to take safety and health education is strengthened, and effective case education is proposed by teaching actual accident cases suitable for actual working sites. It is necessary to make all training mandatory, and it is necessary to reconsider awareness through writing a daily safety log, awareness of risk factors, etc., and writing down risk information. Above all, at the construction ordering stage, it is necessary to keep the construction safety, request corrections and supplements for problems issues that arise, and consult between the orderer and the construction company about the problems issues. Rather than having only the construction company correct or supplement the safety management plan, the contents should be shared with supervisors and workers to establish a more practical solution. Results of this study will contribute to improving the effectiveness of the serious accident and construction safety management system.

이 연구의 목적은 뉴질랜드 웰빙 예산의 목표와 효과를 탐색적으로 분 석하는 것이다. 문헌분석 방법을 활용하여 웰빙 예산의 도입과정, 프레임 워크, 예산목표, 예산항목을 살펴보고, 웰빙 예산의 목표달성 정도에 따 른 효과성을 탐색적으로 파악하기 위해 웰빙 예산 도입 전후의 변화를 정부 통계 데이터를 통해 확인하였다. 분석 결과, 뉴질랜드는 2019년부 터 현대 국가에서 최초로 공식 예산 명칭에 ‘웰빙’이라는 용어를 사용하 였고, 생활 수준 프레임워크에 기반하여 5대 예산목표(정의로운 전환, 신 체적·정신적 웰빙, 노동의 미래, 마오리족과 태평양 지역주민, 아동 웰빙) 를 달성하고자 웰빙 예산의 연속성을 구현하여 왔다. 5대 예산목표의 달 성 효과는 아직 미약하나, GDP가 아닌 웰빙을 예산 수립의 궁극적 목적 으로 천명하였다는 점에서 웰빙 예산은 의의를 가질 수 있다. 생활 수준 프레임워크 개발, 지역과 마을에서의 주민참여예산제를 통한 사회연대, 예산의 주무부처가 아닌 모든 부처가 동등한 지위에서 협업을 통한 예산 수립 등 한국형 웰빙 예산 개발에 대해 제언하였다.

우리나라에서는 연간 250건 이상의 해양 기름유출사고가 발생하고 있으며, 이는 지역 사회 및 환경에 큰 영향을 미친다. 국제 협약 및 국내법에서는 오염자부담의 원칙을 바탕으로 기름유출에 대한 피해 배상을 유출 당사자에게 책임지도록 하고 있으며, 민·형사적 책임 규명을 위해 유출 행위자에 대한 적극적인 조사가 이루어지고 있다. 기름 유출사고의 행위자 조사의 중요성 확대에 따라서 CEN 15522-2, ASTM D 3248 등의 표준을 이용해 기름 시료 간의 유사성 판정을 하고 있다. 이 중 가장 활발히 활용되고 있는 유럽표준인 CEN 15522-2가 2023년 EN 15522-2로 3차 개정되었다. 본 연구는 EN 15522-2를 이용하여 국내 발생한 해양 기름유출사고 시료를 분석하고, 적용 성에 대하여 확인하였다. 그 결과 경질유 유출사고가 40% 이상을 차지하는 국내 유출사고의 특징을 비춰볼 때 Adamamtanes와 같은 저비 점의 물질이 추가된 EN 15522-2의 적용은 효용성이 높은 것으로 확인되었다.

PURPOSES : The objective of this study was to review roadway management strategies that can be utilized in the event of a radiological emergency, select feasible alternatives, and simulate a portion of the West Coast network to analyze the effectiveness of these strategies. METHODS : The methodology of the study involved reviewing the relevant literature, extracting the implications, establishing an analysis procedure, and selecting an effectiveness evaluation scale. Using a national transportation database, a network was constructed using Toba, a macroscopic model. RESULTS : A reverse-flow lane system was applied to the West Coast Expressway Glory IC–Hampyeong IC (total 25 km), and a plan to increase the number of lanes was applied to the Seokgyo Street–Shinpyeong Intersection on National Route 23 (total extension 28 km). Consequently, both road management strategies were found to be effective. CONCLUSIONS : This study examined roadway management strategies that can be utilized in the event of a radiological emergency, selected feasible alternatives, and simulated a portion of the West Coast network to verify the effectiveness of these strategies. In the case of reverse flow lanes, it is most effective when applied to expressways that can restrict the entrance and exit of vehicles. In the case of increasing the number of lanes, it is most effective when applied to general roads, and institutional arrangements should be made to enable two-way traffic to use the reserved shoulder lanes.

This study analyzed the monitoring results of fishways at 16 weirs constructed on four large Rivers to provide data helpful for the operation and management of fishways. The average utilization rate of the fishways at the weirs was confirmed to be 64.9%. When comparing the dominant species in the mainstream and fishway monitoring results, differences were observed in 9 weirs (56.3%). This indicated that the species prevalent in the mainstream were not necessarily the ones most frequently using the fishways. The average number of individuals using the fishways per day was 336. When classifying the fish species using the fishway by life type, 92.3% were primary freshwater fish, and migratory species accounted for only 5.6%. Analysis based on the season of fishway usage revealed that an average or higher number of fish species used the fishways from May to October, with the highest number of individual users occurring from June to August. Between May and July, 80% of the fish species using the fishways were in their spawning period, while during other season, less than 40% were species that move during the spawning period. The fishways that showed a significant alignment between the spawning period and the fishway passage period were Rhinogobius brunneus, Leiocassis nitidus, Squalidus chankaensis tsuchigae, Pseudogobio esocinus, Acheilognathus rhombeus, and Pungtungia herzi, in that order. When comparing the fishway monitoring results of the Gangjeong-Goryeong Weir and the Dalseong Weir with the upper part water level of the weir, both the number of fish species and individuals using the fishway showed positive correlations with the upper part water level of the weir. This suggests that a higher water level of the weir increases the inflow discharge within the fishway, leading to increased use by fish (number of individuals in Gangjeong-Goryeong Weir, P<0.001; number of species in Dalseong Weir, P<0.05). This study summarized and analyzed the results of fishway monitoring at 16 weirs built on four large Rivers, considering fishway efficiency, operation and management, monitoring period, and regulation of water level in the upper part of the weir. It is thought that this will help understand the status of fish use in fishways on large River and aid the construction, operation, and management of fishways in the future.

This study aimed to investigate the impact of implementing team-based learning (TBL) in postpartum nursing simulation practical education for nursing college students. Methods: The study design was a non-equivalent control group pretest-posttest quasi-experimental design. 128 nursing students divided into two groups: 61 in the experiment group and 67 in the control group. During the winter break in January 2023, students participating in simulation practicals were assigned to the control group, while students participating in simulation practicals during the regular semester (April 2023) were assigned to the experimental group, to prevent crossontamination between the groups due to experimental treatment. Both groups completed selfdministered questionnaires to assess self-directed learning abilities, collaborative self-efficacy, academic achievement, and learning satisfaction. Results: The experimental group showed significantly better compared to the control group, the experimental group showed higher levels of academic achievement and learning satisfaction. Conclusion: It was evident that TBL applied to postpartum nursing simulation practical education is a pedagogical teaching strategy that enhances academic achievement and learning satisfaction. It is necessary to develop and apply team-based simulation practical education not only for challenging obstetric cases but also for labor and delivery nursing, antepartum nursing, and other related areas in clinical practice.

Recently, the government has provided support such as entering new markets, expanding sales channels, and supporting manpower, not just in the form of funding, to efficiently and effectively support limited national resources to improve corporate performance. In this study, we tried to find out the effect of government support for companies that have benefited from the Excellent Technology Research Center Project (ATC Project) and the World Class 300 project using propensity score matching. As a result of the analysis, the effect of government support for the ATC project became visible after the appointment period, while the effect of the World Class 300 project was insignificant. This means that when the size of the company is small, the effect of government support is more pronounced. This suggests that in order to maximize the effectiveness of government support, appropriate national policy interventions such as government innovation funding are needed when the size of the company is small. In this study, differences in the timing, performance indicators, and company size of policy support effects were found in the growth stage of a company from a mid- to long-term time series perspective, suggesting that support policies based on this need to be adjusted and redesigned.

Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

Considering meat consumption's massive impact on climate change, environmental NGOs are increasingly campaigning to encourage consumers to reduce unsustainable meat consumption, i.e., to eat less and/or better meat. They usually use messages based on environmental appeals to do so. Yet, the effectiveness of such appeals in international campaigns may depend on countries as cultural beliefs influence food consumption behaviors. Therefore, in this research, we explore the effectiveness of such campaigns across 5 European countries, controlling for individual cultural orientations. Considering an environmental degradation appeal, we first show that countries have no influence on the campaign’s effectiveness, unlike specific individual cultural orientations, including masculinity and uncertainty avoidance. We replicate these results in the same 5 countries considering an alternative appeal, i.e., animal welfare. Recommendations to international NGOs managers result from these results.

In this article, we address this shortcoming by exploring the concept of AI-based sustainable service—an offering that embeds artificial intelligence in ways that meet the needs of current consumers by contributing to socio-economic equalities and conserving the natural environment.

The present study compared the effectiveness of virtual influencers (VIs) to human influencers through the theoretical lens of the uncanny valley and parasocial relationship using an online experiment. Specifically, we posited that highly humanlike VIs may evoke the feeling of the uncanny valley, as compared to human influencers or cartoonlike influencers, which, in turn, would act as a psychological barrier to building a parasocial relationship with the specific type of virtual influencer and decrease advertising attitude. The results indicated that people do feel the uncanniness from both highly humanlike and cartoonish influencers as compared to human influencers. This particular psychological experience negatively influenced the parasocial relationship, which, in turn, negatively affected the attitude toward a social media advertisement featuring the VIs. However, importantly, this effect was moderated by individual differences in anthropomorphism. This is one of the first studies that directly compared the effectiveness of different types of social media influencers in a rigorously designed experimental setting and expands the previous research on Vis, uncanny valley, and parasocial relationship. Both theoretical and managerial contributions of the study were discussed.
