Risk assessment is useful tool making good decisions on the risks of certain hazardous com-pound and suggests safe margin through scientific process using toxicological data, statistical tool, exposure value and relevant variants. The goal of risk management is to protect the public health from hazardous compound based on result of risk assessment having reality. For the suggestion of exact man-aging information, risk assessment must be designed to represent a "plausible estimate" of the exposure to the individuals and to minimize uncertainty. Risk assessment methodology and knowledge are expected to change more rapidly than before and up-to-date methodology should be applied in regulatory aspects through the Agency. For the useful application of risk assessment, the communication between the risk assessor and the risk manager is needed before the initiation of the risk assessment and upon its completion. Generally, the risk assessment itself as a practical tool in the regulatory decision making process would be regarded with social economic impact.ic impact.

The aim of this study was to present a framework for clinicians to use when discussing electronic cigarette (e-cigarette) use and its association with pre-diabetes. A communication tool was designed using evidence-based strategies from the academic literature. A four-step framework is presented, which includes: step (1) helping patients to understand the association between e-cigarette use and pre-diabetes; step (2) the synergistic health impacts of e-cigarette use and pre-diabetes; step (3) management of diabetes-related lifestyle factors; and step (4) stages of change assessment related to e-cigarette reduction. This communication tool provides support for clinicians to discuss the risk of pre-diabetes associated with e-cigarette use. Moving forward, implementation and evaluation of this model are needed.

Background: As the public interest in chemical substances found in daily life has increased, environmental health education content has been developed and related studies have been conducted. However, there is still insufficient research on methodologies for environmental health education. Objectives: This study aimed to explore risk communication strategies by focusing on N-nitrosamines in rubber balloons. Methods: In this study, two different health messages were composed: a gain-framed message emphasizing the advantages of practicing the health behavior and a loss-framed message emphasizing the negative consequences of not practicing the health behavior. The effect of the message containing risk information was evaluated by measuring the health beliefs and health behavior potential for female caregivers. As the Environmental Health Act defines a child as "a person under the age of 13," a total of 131 women with children under the age of 13 were studied. Results: The age, awareness, and interest of the participants in the gain frame group and these in the loss frame group were similar. In terms of message framing effect, the gain-framed message was more effective in terms of health belief and potential health behavior than was the loss-framed message. As a result of an independent t-test, among the six variables of health belief model the message effect was statistically significant at the level of p<0.05 in three variables: perceived severity (t=2.287, df=129, p=0.024), self-efficacy (t=2.123, df=129, p=0.036), and health behavior potential (t=2.094, df=129, p=0.038). Conclusions: This study presented a direction for effective environmental health education by studying the effects of risk communication messages based on scientific evidence. It is necessary to extend the scope of environmental health education research by expanding research into various household products.

The purpose of this study explains how service characteristics such as service competence, service customization, interpersonal communication and image affect service trust and affective commitments and how service trust, affective commitment play a role in affecting risk-taking and service loyalty in specialty hospital. and then confirm the mediating role of relationship quality components such as service trust and affective commitment in the above path relation. For this purpose, the research hypothesis was verified by structural equation model analysis(SEM) using SPSS 21.0 and AMOS 20.0 statistical package. The results of the study are as follows. First, interpersonal communication influenced service trust, image influenced affective commitment, service ability influenced service trust and emotional commitment, while service customization did not affect any factor. Second, service trust and affective commitment did not effect each other. Third, service trust and affective commitment were more powerful in risk-taking than the influence on service loyalty. Fourth, Risk takings affected service loyalty. Therefore, marketers of special hospitals not only medical services by providing medical service with superior service ability, but also by always strengthening interpersonal communication at the time of providing services. This will enable consumers to overcome the avoidance in the service decision process and implement a specific service marketing strategy that can continuously use the hospital service.

Purpose: This study aimed to develop an emotive role-play program for nursing students focusing on high-risk pregnancy and analyze its effects on communication skills, clinical performance, and emotional intelligence. Methods: A quasi-experimental nonequivalent comparison group design was adopted with 83 nursing students (experimental group, 45; comparison group, 38) who participated voluntarily in an extracurricular program. The preliminary survey was conducted on November 3 and November 4, 2020, and the follow-up survey was conducted on November 12, 2020, for the comparison group and on November 27, 2020, for the experimental group. A program that included five role-play scenarios related to induced labor, preeclampsia, premature rupture of membranes, preterm labor, and infertility was developed by a group of experts and presented to the experimental group over 11 total hours across 3 days. Each student participated in a role-play scenario as a patient, family member, or nurse and observed three other scenarios. The comparison group received a workbook after the follow-up evaluation. The independent t-test was performed to analyze changes in communication skills, clinical performance, and emotional intelligence. Results: Communication skills (t=1.84, p=.035) and clinical performance (t=2.75, p=.004) significantly increased in the experimental group compared to the comparison group. A significant difference was not observed between the experimental and comparison groups for emotional intelligence (t=1.36, p=.088). Conclusion: The emotive role-play program concerning high-risk pregnancy was effective in improving nursing students' communication skills and clinical performance and can be used in nursing education related to high-risk pregnancy and childbirth.

The purpose of this paper is to deduct components that are in the group of highest risk(top 10%). the group is conducted for classification into groups by values according to risk priority through risk priority number(RPN) of FMEA(Failure modes and effects analysis) sheet. Top 10% of failure mode among total potential failure modes(72 failure modes) of ESS included 5 BMS(battery included) failure modes, 1 invert failure mode, and 1 cable connectors failure mode in which BMS was highest. This is because ESS is connected to module, try, and lack in the battery part as an assembly of electronic information communication and is managed. BMS is mainly composed of the battery module and communication module. There is a junction box and numerous connectors that connect these two in which failure occurs most in the connector part and module itself. Finally, this paper proposes RPN by each step from the starting step of ESS design to installation and operation. Blackouts and electrical disasters can be prevented beforehand by managing and removing the deducted risk factors in prior.

본 논문은 단일 종목에 투자금을 전액 투자하는 것에 비해 다수의 종목에 분산투자하는 것이 투자 위험을 보다 감소시킬 수 있다는 포트폴리오 최적화 문제를 다룬다. 널리 알려진 Markowitz의 수익률에 대한 평균-분산 기법(MV)은 위험요인인 분산(또는 표준편차)을 감소시키기 위해 지배원리를 적용하여 효율적 투자선에 있는 종목들을 대상으로 분산투자하는 포트폴리오를 구성하였다. 반면에, 본 논문에서는 최소표준편차를 가진 종목을 필수 투자종목으로 선정하고, 필수 투자종목과 비양(음의, 무)의 상관관계를 갖는 종목들을 대상으로 포트폴리오를 형성하였다. 제안된 방법을 실험한 결과 MV에 비해 보다 적은 위험(표준편차)을 보였다.
