The rapidly growing global population increases the awareness of water, energy, and food security worldwide. The concept of Water, Energy, and Food nexus (hereafter, WEF nexus) has been widely introduced as a new resources management concept that integrate the water, energy, and food in a single management framework. Recently, WEF nexus analyzes not only the interconnections among the resources, but also considers the external factors (such as environment, climate change, policy, finance, etc) to enhance the resources sustainability by proper understanding of their relations. A nation-level resources management is quite complex task since multiple regions (e.g., watersheds, cities, and counties) with different characteristics are spatially interconnected and transfer the resources each other. This study proposes a multiple region WEF nexus simulation and transfer model. The model is equipped with three simulation modules, such as local nexus simulation module, regional resources transfer module, and optimal investment planning module. The model intends to determine an optimal capital investment plan (CIP), such as build-up of power plants, water/waste water treatment plants, farmland development and to determine W-E-F import/export decisions among areas. The objective is to maximize overall resources sustainability while minimize financial cost. For demonstration, the proposed model is applied to a semi-hypothetical study area with three different characterized cities. It is expected the model can be used as a decision support tool for a long-term resources management planning process.

The study examined the XBRL adoption process of Malaysian Business Reporting System (MBRS) by utilizing Everett Rogers' Diffusion of Innovation (DOI) theory. The study focused on the three phases, namely, knowledge gathering and persuasion phase, decision-making phase, and implementation phase of XBRL adoption process gathered from a government agency in Malaysia. This study employs a qualitative case study that incorporates semi-structured interviews with four members of the regulator. The results reveal that the regulator has realized the advantages, management support, and need to skills development in phase one. On the other hand, in phase two, it finds the way the regulator makes decision related to XBRL taxonomy and submission template, platform, tools and software. Through phase three, the regulator is concerned with the complexity of XBRL taxonomy, resources, external support, promotion, stakeholder involvement, limited trading pressure, critical mass, and professional bodies. The factors from each phase suggest an in-depth understanding on the experience of XBRL through the development of MBRS that provides a success story to the other government agencies and regulators in Malaysia. This study provides several insights on the factors that could contribute to the adoption of XBRL and the Diffusion of Innovation theory adoption process.

This study examines the normalization of Korean GM management between the Korean government and GM in terms of external negotiation game and internal negotiation game using Putnam's Two-Level Games. In addition, GM's Win-set change and negotiation strategy were analyzed. This analysis suggested implications for the optimal negotiation strategy for mutual cooperation between multinational corporations and local governments in the global business environment. First, the negotiation strategy for Korea's normalization of GM management in Korea can be shifted to both the concession theory and the opposition theory depending on the situation change and the government policy centered on the cautious theory. Second, GM will maximize its bargaining power through 'brink-end tactics' by utilizing the fact that the labor market is stabilized, which is the biggest weakness of the Korean government, while maintaining a typical Win-set reduction strategy. GM will be able to restructure at any time in terms of global management strategy, and if the financial support of the Korean government is provided, it will maintain the local factory but withdraw the local plant at the moment of stopping the support. In negotiations on the normalization of GM management in Korea, it is necessary to prepare a problem and countermeasures for various scenarios and to maintain a balance so that the policy does not deviate to any one side.

The study aimed to understand medical students' experiences of emotional changes, including their method of adapting to experiences, and the effect of the experiences in shaping their identities. We interviewed 12 medical students who were finishing their 1-year clinical internship in 2016. Data on their opinions and reasons for emotional changes during their school life were obtained. The descriptive phenomenological approach was applied to analyze the interviews. Their stress came from disappointment in themselves, competitive environment, observing a change in their personalities, meeting their parents' expectations, and interpersonal relations. The interviewees adjusted to the medical study by exercising self-control in their studies and daily lives, by practicing self-acceptance and observing their state of mind, and by breaking free from the competition-driven environment and obsession with grades. In addition, they cultivated endurance and found external support. Finally, they achieved self-efficacy and were comfortable in their identity as medical students. They still had to address the stress from working relationships and the difficulty in balancing studies and life. The medical students' self-evaluation and compulsive tendencies increased during the medical course due to the burden of studies. They evolved by learning self-control and introspection and seeking ways to adapt. Understanding this growth process of medical students will improve student support in medical schools.

The open space of the healing facility should contribute to the psychological and social healing of the users, provide a social environment for rest, and provide a design factor to support the walking path to move to the destination-connected space. In this paper, I examined the relationship between the environmental elements, spatial devices, and the characteristics of the design factors in the open space for healing facilities. As a research method, based on the analysis of previous studies, a healing facility in modern society was defined, and the relationship between the social support and physical environment factors of the healing facility where open space was considered. Through the consideration of cases, the characteristics of the physical space environment, and the design factors of the open space in the healing facility were categorized. As a result of research, open space in the healing facility is a space to promote a social exchange of users, as a physical form for accommodating psychological and social healing functions, it is necessary to construct the connection of the external space with the internal space.

The passive safety systems (PSSs) within water-cooled reactors are meticulously engineered to function autonomously, requiring no external power source or manual intervention. They depend exclusively on inherent natural forces and the fundamental principles of reactor physics, such as gravity, natural convection, and phase changes, to manage, alleviate, and avert the release of radioactive materials into the environment during accident scenarios like a loss-of-coolant accident (LOCA). PSSs are already integrated into such operating commercial reactors as the Advanced Pressurized Reactor-1000 MWe (AP1000) and the Water-Water Energetic Reactor-1200 MWe (WWER-1200) are adopted in most of the upcoming small modular reactor (SMR) designs. Examples of water-cooled SMR PSSs are the passive emergency core-cooling system (ECCS), passive containment cooling system (PCCS), and passive decay-heat removal system, the designs of which vary based on reactor system-design requirements. However, understanding the accident-event progression and phases of a LOCA is pivotal for adopting a specific PSS for a new SMR design. This study covers the accident-event progression for direct vessel injection (DVI) small-break loss-of-coolant accident (SB-LOCA), associated physics phenomena, knowledge gaps, and important figures of merit (FOMs) that may need to be evaluated and assessed to validate thermal-hydraulics models with an available experimental dataset to support new SMR design and development.

최근 대학생들의 취업스트레스 정도가 심각해지면서 단기간의 개입 프로그램이나 상담을 통해 취업스트레스의 부정적 영향을 완화시킬 수 있는 변인이 무엇인지에 대한 관심이 높아지고 있다. 이에 본 연구에서는 취업 준비생의 취업스트레스가 우울과 심리적 안녕감에 어떠한 영향을 미치는지 알아보고, 이 관계에서 자아탄력성(내적 변인)과 사회적 지지(외적 변인)가 조절 역할을 하는지 알아보고자 하였다. 즉, 취업스트레스가 우울과 심리적 안녕감에 미치는 부정적 영향을 자아탄력성과 사회적 지지가 감소시키는지 살펴보았다. 이를 위해 4년제 대학에 재학 중인 4학년 이상 재학생과 대학 졸업생 중 사기업과 공기업에 취업하기를 희망하는 취업 준비생 264명을 대상으로 수집한 자료를 분석하였다. 그 결과, 취업스트레스가 우울에 미치는 영향에서 자아탄력성은 조절 역할을 하는 반면에 사회적 지지는 조절 역할을 하지 않는 것으로 나타났다. 이에 반해 자아탄력성은 취업스트레스가 심리적 안녕감에 미치는 영향을 조절하지 않지만, 사회적 지지는 조절하는 것으로 나타났다. 이와 같은 결과는 자아탄력성이 높을수록 취업스트레스가 우울에 미치는 영향이 감소되는 반면에 사회적 지지가 높을수록 취업스트레스가 심리적 안녕감에 미치는 영향이 감소됨을 의미한다.

COVID-19로 인해 전 세계적으로 경제는 악화되었으며 국내 역시 큰 타격을 받게 되었다. 이에 정부는 중소기업들이 겪고 있는 자금난 해소를 위해 전례 없는 COVID-19 관련 재정지원 정책을 시행하였다. 또한, 정부는 COVID-19 확산이 지속되자 비대면 접촉을 권고했으며 그에 따른 지침과 방안을 내세움에 따라 공공부문과 민간부문의 조직들은 비대면 형태의 업무방식을 도입하였다. 이러한 상황을 고려하여 본 연구는 COVID-19 관련 재정지원 정책이 중소기업의 혁신에 미치는 영향을 규명하였다. 또한, 기업의 혁신을 위해서는 정부의 지원과 같은 외부적인 지원도 중요하나 내부적 역량 역시 중요한 요인에 해당한다. 따라서 기업가정신이 제품혁신에 미치는 영향을 파악하였으며, 더하여 비대면 형태의 업무방식이 활성화됨에 따라 스마트워크를 도입한 기업과 도입하지 않는 기업 간 비교를 통해 스마트워크의 효과를 파악하였다. 가설검증을 위한 자료수집은 과학기술정책연구원에서 제공하는 한국기업혁신조사-2020년 (제조업)의 자료를 활용하였다. 또한, 가설검증을 위해 성향점수매칭을 이용해 표본에 대한 선택편의를 줄인 이후 스마트 도입 기업과 도입하지 않은 기업 간 집단을 분류하여 다중회귀분석을 시행하였다. 분석결과는 다음과 같다. 기업가정신의 경우 스마트워크 도입 여부에 상관없이 중소기업의 제품혁신에 정(+)의 영향을 미쳤다. COVID-19 재정지원정책의 경우, 금융지원은 스마트워크를 도입한 기업에게만 제품혁신에 정(+)의 영향을 미쳤으며 이외에 지원정책은 스마트워크 도입 여부에 상관없이 제품혁신에는 효과가 없는 것으로 나타났다. 분석결과 기업가정신은 스마트워크 도입 여부에 상관없이 정(+)의 영향을 나타냈으며, COVID-19 관련 재정지원정책은 지원유형에 따라 혼재된 결과를 보여주는 것으로 나타났다. 이러한 분석결과를 토대로 정책적 및 학문적 시사점을 제시할 수 있었다.
