Purpose: This study aimed to explore the weight loss experience of highly obese young people who underwent bariatric surgery. Methods: Data were collected, from October 2021 to April 2022, through individual in-depth interviews with eight highly obese young adults who underwent bariatric surgery and analyzed using Colaizzi's phenomenological method. Results: The following four theme clusters were extracted. First, 'The unbearable sorrow of obese people' explains the process of choosing bariatric surgery after fluctuations and frustration despite countless repeated weight loss attempts. Second, 'The impact aftermath of bariatric surgery' revealed participants struggling in the face of unexpected changes due to bariatric surgery. Third, 'Efforts to rebuild a healthy myself' demonstrated the struggle to regain health by using the surrounding support system to overcome the difficulties of this surgical procedure. Lastly, 'Facing life by getting rid of the yoke of obesity' displayed the experiences of the participants who felt ambivalent about their changed appearance, but coping positively with the new life. Conclusion: This study provides an in-depth understanding of the weight loss experiences of highly obese adolescents who underwent bariatric surgery and presents a new perspective on clinical practice. The results of this study are expected to be useful in developing and applying systematic and customized nursing interventions before and after bariatric surgery.

건설업은 경기에 민감하게 반응하며 완전 경쟁에 가까운 산업 구조를 갖기 때문에 재무 상태가 취약한 기업은 불황기에 손쉽게 도태될 수 있다. 건설 기업의 지속적 생존과 성장을 도모하기 위해서는 재무 상태와 경영 성과를 반복적으로 측정할 필요성이 있다. 이에 본 연구는 2000년부터 2019년까지 최소한 한 번 이상 외부감사를 받은 건설 기업 6,252개의 재무제표를 사용하여 합산 재무제표를 생성하였고, 이 재무제표를 기준으로 건설 기업의 평균적인 재무 상태와 경영 현황을 파악하였다. 이 과정을 통하여 건설업은 매출액 성장과 이익률 개선에 한계가 있으며 높은 레버리지비율은 재무적 안정성을 해할 수 있으므로 총자산회전율 개선과 같은 생산효율을 추구하는 경향을 발견하였다. 이 경향은 2008년 세계금융위기 이후에 더 선명하게 나타났다.

This paper presents the development of seismic fragility curves for a precast reinforced concrete bridge instrumented with a structural health monitoring (SHM) system. The bridge is located near an active seismic fault in the Dominican Republic (DR) and provides the only access to several local communities in the aftermath of a potential damaging earthquake; moreover, the sample bridge was designed with outdated building codes and uses structural detailing not adequate for structures in seismic regions. The bridge was instrumented with an SHM system to extract information about its state of structural integrity and estimate its seismic performance. The data obtained from the SHM system is integrated with structural models to develop a set of fragility curves to be used as a quantitative measure of the expected damage; the fragility curves provide an estimate of the probability that the structure will exceed different damage limit states as a function of an earthquake intensity measure. To obtain the fragility curves a digital twin of the bridge is developed combining a computational finite element model and the information extracted from the SHM system. The digital twin is used as a response prediction tool that minimizes modeling uncertainty, significantly improving the predicting capability of the model and the accuracy of the fragility curves. The digital twin was used to perform a nonlinear incremental dynamic analysis (IDA) with selected ground motions that are consistent with the seismic fault and site characteristics. The fragility curves show that for the maximum expected acceleration (with a 2% probability of exceedance in 50 years) the structure has a 62% probability of undergoing extensive damage. This is the first study presenting fragility curves for civil infrastructure in the DR and the proposed methodology can be extended to other structures to support disaster mitigation and post-disaster decision-making strategies.

Debates continue to multiply on the definition and rationale of Southeast Asia as a region and on the utility of the multidisciplinary field of area studies. However, we have now entered a post-colonialist, post-Orientalist, post-structuralist stage of reflection and re-orientation in the era of globalization, and a strong tendency on the part of insiders to pose these issues in terms of an insider-outsider dichotomy. On the one hand, the study of Southeast Asia for researchers from outside the region has become fragmented. This is for very obvious reasons: the strengthening and re-energizing of academic disciplines, the increasing popularity of other non-regional multidisciplinary studies, and the entry of globalization studies into our field of vision. On the other hand, how has the local Southeast Asian academy addressed these major issues of change in conceptualizing the region from an insider perspective? In filling in and giving substance to an outsider, primarily Euro-American-Australian-centric definition and vision of Southeast Asia, some local academics have recently been inclined to construct Southeast Asia in terms of the Association of Southeast Asian Nations (ASEAN): a nation-state-based, institutional definition of what a region comprises. Others continue to operate at a localized level exploring small-scale communities and territories, while a modest number focus on sub-regional issues (the Malay-Indonesian world or the Mekong sub-region are examples). However, further reflections suggest that the Euro-American-Australian hegemony is a thing of the past and the ground has shifted to a much greater emphasis on academic activity within the region. Southeast Asia-based academics are also finding it much more important to network within the region and to capture, understand, and analyze what Chinese, Japanese, and Korean scholars are saying about Southeast Asia, its present circumstances and trajectories, and their increasingly close involvement with the region within a greater Asia-Pacific rim. The paper argues that the insider-outsider dichotomy requires considerable qualification. It is a neat way of dramatizing the aftermath of colonialism and Orientalism and of reasserting local priorities, agendas, and interests. But there might be a way forward in resolving at least some of these apparently opposed positions with recourse to the concepts of culture and identity in order to address Southeast Asian diversities, movements, encounters, hybridization, and hierarchies.

The main purpose of this research is to analyze the changes in investment motivation by year through time series and cross-sectional analysis of the factors and investment decisions of Korean manufacturing companies. According to the investment pattern for Asean from the 1980s to the 19th, the first expansion period was 82 to 86, the average increase in overseas investment for securing foreign raw materials due to the second oil shock, and the second expansion period was a gradual increase in exports to the U.S. in 1987 to 1996. During the first stagnation period, direct investment in Asean stagnated in the aftermath of the 1998-05 Asian crisis, and in the third expansion period, part of the production facilities invested in China were relocated to Asean, increasing Asean's investment to become Korea's largest manufacturing investment in 17. Korea's proportion of investment in Asean surpassed that of mass investment since 10 years ago, and the proportion of investment in manufacturing sector has been transferred from China to Asean, and after 17 years, it has served as an overseas production base connecting China. As such, The main purpose of the research will be to extract the determinant factors and key factors for overseas direct investment and investment patterns in conjunction with global manufacturing companies' production base relocation and investment trends through empirical analysis. This research paper gave basic reference to the motivation and determinant of investment 16 years ago, and analyzed the changes in investment motivation by year and content through empirical analysis, contributing some reasonable purpose to the decision of companies and policy makers interested in overseas direct investment.

Background: Despite many environmental problems, plastic waste emissions have been a significant surge during last few decades in the Republic of Korea. Furthermore, the emergence of the coronavirus disease 2019 (COVID-19) pandemic has lead to an increased use and disposal of plastic waste worldwide. This paper tried to present summarized data related to the production and disposal of plastics especially before and after the COVID-19 pandemic with environmental impacts of plastics. Also, review of plastic waste reduction policies and feasible policies to promote an act for a safe, sustainable environment are presented. Results: Plastics cause many environmental problems due to their non-degrading properties and have a huge direct and indirect impact on Ecosystems and Public Health. Microplastics need a lot of attention because their environmental effects are not yet fully identified. Despite plastic's significant impact on climate change, the impact is not yet widely known to the public. Since the COVID-19 pandemic, the use of plastic has surged and recycling has decreased due to the increase in delivery food and online shopping. Korea is introducing very active plastic and waste management policies, but it is necessary to implement more active policies by referring to the cases of other countries. Conclusions: In this article, we have scrutinized the evolution of plastic waste generation in the aftermath of the COVID-19 pandemic and delved into policy frameworks adopted by other nations, which South Korea can draw valuable lessons from. The formidable challenges posed by plastic waste, the remarkable shifts witnessed during the COVID-19 era, and the multifaceted response strategies elucidated in this paper all play a pivotal role in steering South Korea toward a sustainable future.

Analyzing the aftermath of events at domestic nuclear power plants brings in the question: "Why do workers not comply with the prescribed procedures?" The current investigation of nuclear power plant events identifies their reasons considering the factors affecting the workers' behaviors. However, there are some complications to it: in addition to confirming the action such as an error or a violation, there is a limit to identifying the intention of the actor. To overcome this limitation, the study analyzed and examined the reasons for non-compliance identified in nuclear power plant events by Reason's rule-related behavior classification. For behavior analysis, I selected unit behaviors for events that are related to human and organizational factors and occurred at domestic nuclear power plants since 2017, and then I applied the rule-related behavior classification introduced by Reason (2008). This allowed me to identify the intentions by classifying unit behaviors according to quality and compliance with the rules. I also identified the factors that influenced unit behaviors. The analysis showed that most often, non-compliance only pursued personal goals and was based on inadequate risk appraisal. On the other hand, the analysis identified cases where it was caused by such factors as poorly written procedures or human system interfaces. Therefore, the probability of non-compliance can be reduced if these factors are properly addressed. Unlike event investigation techniques that struggle to identify the reasons for employee behavior, this study provides a new interpretation of non-compliance in nuclear power plant events by examining workers' intentions based on the concept of rule-related behavior classification.
