Since a severe accident, which happens in low frequency, can cause serious damages, the interests in off-site consequence analysis for a nuclear power plant have been increased after Chernobyl, TMI and Fukushima accidents. Consequences, which are the effects on health and environment caused by released radioisotopes, are evaluated using MACCS II code based on the method of Level 3 PSA. To perform a consequence analysis for the reference plants, the input data of the code were generated such as meteorological data, population distribution, release fractions, and so on. Using these input data, acute and lifetime dose as an organ, CCDF for early fatalities and latent cancer fatalities, and average individual risk were analyzed by using MACCS II code in this study. These results might contribute to establishing accident management plan and quantitative health object.

Objectives: To propose the basic data for the development of the optimum health promotion program (HPP) for the workers in a petrochemical industry complex. Methods: The subjects were 553 workers who worked at the six plants in a petrochemical industry complex. From February to March 2003, questionnaire survey was conducted by the nurses with occupational health specialty about the life styles, interests, self-cognitions, practices of health behavior, subjective symptoms thought to be related the working environments, burden to the own health, needs and intentions to participation of the HPP. Data analysis was done using SPSS program (ver 10.0) with ${\alpha}=0.05$ of statistical significance. Results: The mean age and tenure of the subjects were 39.7 years and 14.2 years, respectively, and proportion of smokers was around 50%. Two of third (66%) satisfied their own job, and 58% recognized themselves healthy. The most frequent health behavior were exercise (60%) and regular health check (87%) in individual and job based, respectively. About half of them (58%) had at least one of the symptoms thought to be related the working environments, and the most frequent one was odor (21%). These symptoms were more frequent in case of the shorter career. The needs of HPP was relatively higher in exercise (66%), cancer prevention (51%), stress control (47%), and intention to participation was also the highest in exercise (64%). Job satisfaction was higher in case of the higher interests and cognitions to their own health, and thought that the ownership's interest to workers' health be high (p<0.01), but no associations with the subjective symptoms. The mean level of burden to the own health were $14.1{\pm}13.9$ of physical, $11.7{\pm}13.6$ of emotional, $9.1{\pm}10.7$ of behavioral as out of one hundred. They felt the more burden in case of office workers, the lower interests and cognitions to their own health, the lower satisfaction to their job, the frequent drinking group, and complained the subjective symptoms (p<0.05). Abnormal results of the regular health check was higher in the frequent drinking group (p=0.083). Conclusions: For the optimum HPP for the workers in the petrochemical complex, the ownership's interest to workers' health would be enhanced, and the priority would be focused on exercise and drinking habits control.

Purpose - The field of online videos has seen rapid changes in information and communications technology (ICT) development. Despite active academic research on the use of online platforms, few studies have analyzed the relative importance among the factors determined. In this study, the relative importance of factors found in previous studies was identified for users of online video platforms in China and Korea. Through this, factors that should be considered first in research on online video use were derived. In addition, the quality level of online video platforms currently used in China and Korea was measured and used for analysis. The analysis results can provide information for companies to enter Chinese and Korean markets and also be useful to platform providers aiming to increase usage. Design/methodology - Among the factors of Online Video Usage identified in previous studies, 13 factors to be studied were selected through focus group interviews and hierarchized into 2 layers. For the analytic hierarchy process (AHP), each factor was designed as a pairwise comparison questionnaire. The survey included questions on the quality of online video platform currently in use. Data collection was conducted on 16 platforms in China and 11 platforms in Korea, and the relative importance of factors and user perspectives was compared and analyzed using importance performance analysis (IPA). In the analytical process, platforms were divided into over-the-top (OTT) group and Creator group according to the weight of user-generated content, and data analysis focused on these groups. Findings - As a result of AHP, China and Korea showed both "Fun" and "Interests" factors at the top, while the importance of the Entertainment factor "Vicarious satisfaction" was very different for China and Korea. "Relationship with content creators" was the most important factor in China, but it ranked the lowest in Korea. The IPA showed that the factors with high importance and performance were fun, interests, and easy accessibility for both China and Korea. In contrast, the factors that showed low performance compared to high importance in China were relationship with content creators, relationship with acquaintances/friends, and trustworthiness. As for Korea, vicarious satisfaction was observed; thus, this study has raised the need for academic and industrial interest in vicarious satisfaction. The results show that fun, interests, vicarious satisfaction, and easy accessibility of the platform are factors that must be included in further studies on online videos. Originality/value - Existing studies related to the use of online platforms have derived factors or focused on the influence relationship between factors and performance. However, few studies have analyzed the relative importance among the determined factors. This paper explores factors to be considered in future studies by deriving the relative importance between these factors from the perspective of users in China and Korea.

본 연구는 지상파 방송(KBS, MBC, SBS)이 자사의 이익과 관련된 이슈를 어떻게 보도하고 있는지 알아보고자 했다. 이를 위해 세 건(광고총량제, 700MHz 대역 주파수 재분배, 수신료 인상)의 이슈를 선정했고, 양적 내용분석을 통해 관련 뉴스에 드러난 보도 톤, 정보원 활용, 뉴스 프레임을 분석했다. 연구 결과, 지상파 3사 모두 자사의 이익과 관련된 사안을 보도할 때 보도 톤과 정보원 그리고 프레임 활용에서 자사의 입장을 대변하는 보도태도를 드러내고 있었다. 보도 톤 분석에서는 세 건의 이슈와 관련된 뉴스의 90%가 방송사의 입장과 일치하는 보도 톤을 갖는 것으로 드러났다. 뉴스에 활용된 정보원의 유형과 입장을 분석한 결과, 정보원의 유형은 비교적 다양했으나 주로 방송사의 입장과 동일한 입장을 가진 정보원을 활용한 것으로 확인되었다. KBS만 해당하는 수신료 인상 건은 보도 톤이나 정보원의 입장에서 다른 두 사안에 비해 중립적인 보도태도가 다소 보였지만 절대적인 측면에서는 역시 자사의 입장을 대변하는 보도가 주를 이루었다. 프레임 분석결과에서는 이슈별로 프레임 활용에 차이가 있음을 확인할 수 있었다. 광고총량제 관련 뉴스에서는 책임귀인프레임이 주로 활용되었고 700MHz 대역 주파수 재분배 이슈의 뉴스에서는 지상파 방송의 공익성 강조 프레임이 가장 주요한 프레임이었다. 한편, 수신료 인상 관련 뉴스에서는 책임귀인 프레임과 지상파 방송의 공익성 강조 프레임이 비슷한 수준으로 활용된 것을 알 수 있었다.
