  • Objective: The aim of this study is to review the job stress measurement for applying in nuclear power plants(NPPs). Background: The standard and guideline to evaluate and manage the job stress is insufficient in NPPs. Although job stress might have a negative effect on task performance particularly it can be related with human error in NPPs. Method/Results: This paper considered the objective and subjective stress measurements. One of the questionnaire(Korean Occupational Stress Scale) and the experiment method was investigated to apply in NPPs. KOSS was analyzed about the inter item consistency and correlation with the workload, and relative importance. In the objective evaluation considered the experiment method for the physical and mental job stress and analyzed from the phased point of view. Conclusion/Application: The measurement and criteria to evaluate job stress for operators must be complemented on the job characters and environments in NPPs. This study may support to confirm and manage the job stress in NPPs. The study of more specific methodology on job stress in NPPs is required on the basis of this paper.

  • Anxiety is one of the basic human emotions. From the evolutionary psychology point of view, it is a necessary factor for survival and prosperity of human beings that had been developed throughout time with the history of human survival and development. Anxiety plays the role of protecting one from social or physical threats. In reality, lacking of anxiety showed lots of examples of maladjustments. But the result of over-adjustment, which is overanxious disorder, is definitely disturbing one's survival and growth, and it can lead to anxiety disorder that needs to be treated. Anxiety from the evolutionary psychology point of view, started as a primary adjustment form and it evolves into various types of anxiety disorders that relates to the modern society's characters. Therefore, having the grasp of evolutionary psychology, which can be the base of treating anxiety and anxiety disorders, is very important. So from now on, studies for this aspect would need to be done as integrated and multidisciplinary studies not only by psychiatrists, but by including epidemiologists, psychologists, ecologists, biologists, and neuropsychologists. In this article, the author tried to review and explore the idea of anxiety and anxiety disorders from the evolutionary psychology point of view.

  • There are many design parameters affecting filtration efficiency such as filteration rate, media packing depth, size distribution, and so on. The sphericity, the ratio of the surface area of an equal volume sphere to the real surface area of the particles, is one of major physical characters of media. The effect of sphericity on the performance of anthracite filter has been investigated. Media from eight water treatment plants have been collected. The sphericity of each media has been calculated by using well known headloss equations such as Kozeny equation, Dahmarajah equation etc.. Columns packed with anthracite media having different sphericity have been used to compare headloss development, floc accumulation in the bed, particles in bed water, filtrate turbidities after backwash and so on. The repeated experiments have indicated that the sphericity of anthracite media may not have remarkable influence on the filter performance as it has been suspected. It also has been prospected in the experiment that the media of higher sphericity would store more particles in the bed and give better filtrate quality, if provided that the effective size and the size distribution of media would be the same.

1930-1990년대 영화 의상에 나타난 젠더 정체성(I) -남성성(Masculinity), 여성성(Feminity)를 중심으로- (A Study on Gender Identity shown in Movie Costumes from 1930′s to 1990′s -Focused on Masculinity and Feminity-)

  • The movie costumes may serve to change individuals'ego identity, shift a gender identity to another one and make multiple and plural gender identities shared. The unique identities shown in movies can influence the audience to the extent that they will imitate characters's costumes or appearance in their real life, replacing their inner, unrealizable and private fantasy with real one. The purpose of this study is to review the movies produced in 1930's and thereafter by categorizing the socio-cultural gender concepts into masculinity and feminity. Masculinity and Feminity are not attributions fixed by some physical characteristics, but it tends to be changed or expended by some social factors over time. In short, it may be a flexible, plural, individual and self-introspecive attribute. Movies present diverse types of masculinity and feminity, and in particular, the movie costumes specify them. In other words, the costumes may be model means expressing the masculinity and feminity, and the gender identities shown in the movies tend to be imitated, re-created or assumed by the audience. All in all, the movie costumes serve to take on the confrontation of masculinity and feminity between inner, unrealizable and private fantasy and external reality and thereby, expand it from internal to external issue and thus, change or reform masculinity and feminity.

  • The purpose of this study was to examine the differences in terminologies used in South and North Korea, to describe objects or activities related to clothing and textiles, as a part of a bigger project that aims at developing an educational program in provision of reunification of the Koreas. In this study, a total of 176 North Korean terms that differ from South Korean terms were collected from various sources, including dictionaries that are developed to compare South-North Korean languages as well as texts such as magazines and news articles, about North Korean daily life. The terms were classified into sub-categories: materials for clothing, clothing management, construction and design, garment names, body parts, description of physical appearance or state of hygiene, and apparel industry. Many of the North Korean terms were derived from native expressions, rather than adopting foreign terms or terms in Chinese characters. Some North Korean terms did not have any corresponding words in South Korean terms or vice versa. We expect the terminology list to become a useful educational resource in establishing a clothing and textiles curriculum in preparation of reunification, by allowing the students to familiarize with the differences in the usage of terms.

  • It is over 100 years after Lee Je Ma has proposed concept of the Sasang constitutional medicine in his book DongEuiSooSeBoWon in 1894. As well known, this concept describes four constitution of Taeyang, Taeum, Soyang, and Soeum which are deals with physical body status and shape, desease and symptoms, personal characters, and organ function. In these days there are growing needs to elucidate this Sasang concept by the scientific manner, especially by biological tools. However there are no genes revealed related to the Sasang and moreover it is not easy to give a biological evidence for the Sasang constitution. Here are some considerations about the brief history of biological research on the Sasang constitution, and some prospectives of how to do to find genes of Sasang, and which to be done for what is about Sasang.

  • High-rise and high-density apartment complexes has been built and supplied on a large scale in the metropolis and metropolitan areas since 1980s in order to solve housing shortage in cities. Recently they are raising deterioration problems for aging more than 20 years. moreover, those problems show very special characters such as simultaneity and a large scale. The purpose of this study is to propose a direction for the development of the evaluating indicators to measure the level of deterioration of apartments. The level of deterioration of apartments can be evaluated by housing performance. In order to evaluate the deterioration comprehensively, the housing performance indicators should be developed on the social, economical, and physical dimension. This study analyzed the concept of the apartment deterioration and compared housing performance indicators through literature review. First of all, when considering various factors in the evaluation of the deteriorated apartments, such as evaluating ranges, attributes and dimensions, housing performance indicators should be structured with the hierarchical framework. Second, housing performance indicators evaluating the level of deterioration of apartments should include social, psychological, and cultural aspects of home environments in order to understand adequately the attitude of the middle class toward services that apartments provide. Third, in previous researches, most criteria have been developed and weighted based on only expert opinions regarding performance indicators. So, It is necessary to include residents' opinions in developing performance indicators since they can provide more practical and feasible aspects the experts could not experience or understand.
