본 연구는 학업소진이 학업영역에만 영향을 미치는 것에서 더 나아가, 궁극적으로는 삶의 만족에까지 연결될 수 있음에 주목하였다. 이에 따라 학업소진과 삶의 만족간의 관계를 살펴보고 이들 간 관계에 영향을 미치는 제 3의 변인으로서 위험예측과 이득예측을 상정하여, 학업소진, 위험 예측, 이득 예측이 삶의 만족에 어떠한 과정을 거쳐서 영향을 미치는지 변인들 간의 경로를 규명하여 경로모형을 검증하였고, 이 과정에서 위험 예측과 이득 예측의 역할을 살펴보고자 하였다. 이를 위해 326명의 대학생을 대상으로 설문을 실시하였으며, SPSS 18.0과 Amos 8.0으로 분석하였다. 연구결과, 위험예측은 학업소진과 삶의 만족을 부분 매개하는 것으로 나타났고, 이득예측의 매개효과는 유의하지 않은 것으로 나타났다. 한편, 위험예측은 학업소진이 삶의 만족에 영향을 미치는 과정에서 조절 역할을 하는 것으로 나타났다. 이와 같은 결과를 중심으로 학업소진을 줄이고 전문적 도움 추구에서 위험에 대한 기대를 낮춤으로써 삶의 만족을 높일 수 있는 상담 및 교육의 필요성을 제언하였고, 제한점과 후속 연구의 필요성을 제안하였다.

Purpose: The purpose of this study is how Chinese users' personal traits affect the intention to use mobile payment. This research selects personal innovativeness and habit of cash payment as personal traits, and considers perceived risks and relative advantage as personal beliefs. In addition, the research divided perceived risks into three multi-faceted risks, which are privacy risk, financial risk and performance risk. Methods: The method of this study used questionnaire survey to collect 241 data on users' perception on mobile payment, and also used a structural equation modeling method. Results: The result of this paper shows that all hypotheses are statistically significant except 4 hypotheses. Conclusion: The result of this study found that personal innovativeness is negatively related with all 3 kinds of perceived risks as anticipated. And Chinese users' traditional habit of cash payment negatively affects intention to use mobile payment but is not statistically significant affecting three perceived risks. Among perceived risks, privacy risk is the most negatively influencing factor to relative advantage.

This paper economically analyzes the benefits and concerns of the sharing economy and derives policy implications that could help to achieve the expected benefits and respond appropriately to any concerns. Primary benefits anticipated from the sharing economy are the creation of new transactions and promotional and market testing opportunities, and the main concerns include the crowding out of existing transactions as well as transaction and social risks. How these benefits and concerns are being realized in Korea is empirically examined by conducting a survey on participation experiences with the sharing economy. The sharing economy is expected to contribute to the enhancement of social welfare with its wide range of benefits if risk factors can be properly controlled. Accordingly, an institutional framework is needed to support the stable growth of the sharing economy, and the unique characteristics of non-professional, peer-to-peer transactions should be reflected in tandem with regulatory equity between existing and sharing economy suppliers. To do this, transaction-volume-based regulations are recommended. Furthermore, to secure regulatory effectiveness and to alleviate transaction risks, the pertinent obligations must be imposed on sharing platforms.

Hydrogen is gaining attention as a sustainable and renewable energy source, potentially replacing fossil fuels. Its high diffusivity, wide flammable range, and low ignition energy make it prone to ignition even with minimal friction, potentially leading to fire and explosion risks. Workplaces manage ignition risks by classifying areas with explosive atmospheres. However, the effective installation of a blast wall can significantly limit the spread of hydrogen, thereby enhancing workplace safety. To optimize the wall installation of this barrier, we employed the response surface methodology (RSM), considering variables such as wall distance, height, and width. We performed 17 simulations using the Box-Behnken design, conducted using FLACS software. This process yielded two objective functions: explosion likelihood near the barrier and explosion overpressure affecting the blast wall. We successfully achieved the optimal solution using multi-objective optimization for these two functions. We validated the optimal solution through verification simulations to ensure reliability, maintaining a margin of error of 5%. We anticipated that this method would efficiently determine the most effective installation of a blast wall while enhancing workplace safety.

In December 2019, coronavirus disease 2019 (COVID-19) was discovered in Wuhan, China. The disease was so severe that as early as 30 January 2020 COVID-19 was declared by WHO as a Public Health Emergency of International Concern. There have been a lot of concerns about conducting COVID-19 clinical researches scientifically and ethically in pandemic. This article is directed at addressing these issues from the perspective of IRB. First of all, the urgency of COVID-19 research requires prompt IRB process through efficient ethics review and oversight system. IRB should determine whether the risks that will be presented to human subjects are justified after assessing possible harm and anticipated benefits. The safety of subjects should not be compromised. Furthermore, informed consent should be voluntarily obtained by sufficient information in consideration of special circumstances during a pandemic.
