The purpose of this study was to analyze the characteristics of Women's clothing fashion opinion leaders. The fundamental conceptualization for this study was based on the theories of fashion and opinion leader. Data for the study was obtained through questionnaires from 385 houswives of Gang Nam Gu. The measure of fashion opinion leadership applied in this project was the modification of Rogers' six question self-designating method. Operationally, the characteristic under investigation categoried into three sets of variable ; demographic and socialogical variables, and mass media exposure. As to the data analyses for this study, two-way crosstabs analyses were applied in comparing the characteristics of fashion opinion leader with followers. X\sup 2\ test was used to examine the correlation of several variables. RESULTS : 1. Fashion opinion leaders are not differ from followers in demographic characteristics. 2. Compared with followers, fashion opinion leaders are more active in the participation in concerts, movies and plays. 3. In mass media exposure, fashion opinion leaders differ little from followers regarding T.V, radio, newspaper, literarly magazine, general magazine, culture magazine.

Risk-based screening levels (RBSLs) of some pollutants for residential adults were derived with risk assessment tools developed by United States Environmental Protection Agency (USEPA), American Society for Testing and Materials (ASTM), and Korea Ministry of Environment (KMOE) and compared each other. To make the comparison simple, ingestion of soil, dermal contact with soil, outdoor inhalation of vapors, indoor inhalation of vapors, and inhalation of soil particulates were chosen as exposure pathways. The results showed that the derived RBSLs varied for every exposure pathway. For direct exposure pathways (i.e., ingestion of soil and dermal contact with soil), the derived RBSLs varied mainly due to the different default values for exposure factors and toxicity data. When identical default values for the parameters were used, the same RBSLs could be derived regardless of the assessment tools used. For inhalation of vapors and inhalation of soil particulates, however, different analysis methods for cross-media transfer rates were used and different assumptions were established for each tool, identical RBSLs could not be obtained even if the same default values for exposure factors were used. Especially for inhalation of soil particulates pathway, screening level derived using KMOE approach (most conservative) was approximately 5000~10000 times lower than the screening level derived using ASTM approach (least conservative). Our results suggest that, when deriving RBSL using a specific tool, it is a prerequisite to technically review the analysis methods for cross-media transfer rates as well as to understand how the assessment tool derives the default values for exposure factors.

이 논문에서는 광고분야 매체기획에서 필요한 노출분포 추정과 관련하여 영과잉 분포를 이용한 회귀모형 방법에 대해 살펴보고자 한다. 노출분포란 광고를 반복하여 게재할 때마다 노출되는 청중들의 비율을 나타낸 것이다. 이와 같은 노출분포는 광고효과를 수량적으로 측정하기 위한 각종 지표들을 산출하는데 필요한 기초 정보를 제공한다는 점에서 매우 중요한 역할을 한다. 특히 최근 다양한 매체의 확산으로 인한 광고 단가의 인하로 인하여 과거에 비해 특정 광고의 게재 혹은 방영빈도는 크게 늘어난 상태이나 노출빈도는 상대적으로 줄어들고 있는 상황이다. 이러한 상황에서 해당 매체를 접하지 않는, 즉 구조적으로 광고에 노출되지 않는 개인들이 늘어가고 있다. 이제까지 광고의 노출분포 추정을 위해 사용해 왔던 베타이항분포 등은 이러한 상황에 적합하지 않을 수 있는데, 본 연구에서는 영과잉 회귀모형을 이용한 광고노출분포모형을 제안하고, 실제 사례를 통한 비교연구를 수행하였다.

Objectives: Perchloroethylene (PCE) is a volatile chemical widely used as a solvent in the dry-cleaning and textile processing industries. It was evaluated as Group 2 "probably carcinogenic to humans" by the Integrated Risk Information System (IRIS) of the United State Environmental Protection Agency (U.S. EPA) in 2012. In order to provide a scientific basis for establishing risk management measures for chemicals on the national priority substances list, aggregate risk assessment was conducted for PCE, included in the top-10 substances. Methods: We conducted the investigation and monitoring of PCE exposure (e.g., exposure scenario, detection levels, and exposure factors, etc.) and assessed its multi-media (e.g., outdoor air, indoor air, and ground water) exposure risk with a deterministic and probabilistic approach. Results: In human risk assessment (HRA), the level of human exposure was higher in the younger age group. The exposure level through inhalation at home was the highest among the exposure routes. Outdoor air or uptake of drinking water represented less than 1% of total contributions to PCE exposure. These findings suggested that the level of risk was negligible since the Hazard Index (HI) induced by HRA was below one among all age groups, with a maximum HI value of 0.17 when reasonable maximum exposure was applied. Conclusion: In conclusion, it was suggested that despite low exposure risk, further studies are needed considering main sources, including occupational exposure.

The purpose of this study is to examine the effect of media on plastic surgery experiment. Firstly this study try to find the relationship between exposure to media and other intervening factors(e.g., body image, self-esteem, fashion attitude). The data collected for this study was gathered through questionnaire survey with 443 female students in Seoul. The results are as follows: Using ANOVA, we found that those prefer the magazine over TV or Internet had positive body image, higher self-esteem, and positive fashion attitude(e.g., personality/self-expression, fashion leadership, sexual attraction). Using regression analysis, we found that the we found that the factors influence plastic surgery behavior are the exposure to magazine and the factors influence plastic surgery planning are the clothing attitude (especially fashion leading power, sexual attraction).

Objective : This study was conducted to quantify chronic lead exposure from various media(ie. working environment, food, ambient air), and to certify the usefulness of exposure assessment using Monte-Carlo simulation in the fields of occupational health. Methods : Data were obtained from Korean Industrial Health Association, Korea Food and Drug Administration, and the Ministry of Environment. Then lead worker's exposure was estimated indirectly from various media and parameters (ie. volume inhaled, body weight, dietary intake, etc.). Uncertainty was analyzed by Monte Carlo simulation with Crystal Ball software. Exposure doses and hazard indices were simulated with various hypothetical scenarios including weekly working hours and respiratory protective equipment. Results : Without respiratory protective equipment, the total exposure dose per kilogram of body weight of lead workers was estimated as $5.45{\times}10^{-3}mg/kg/day$, and hazard index was estimated as 2.26, and exposure contributions were calculated as follows : working environment(82.42 %); foods(17.57 %); and ambient air(0.01 %). But, if working condition has changed - reduction of working hours and using respiratory protective equipment, the total exposure dose per kilogram of body weight was estimated between $1.34{\times}10^{-3}-1.49{\times}10^{-3}mg/kg/day$, and hazard index was estimated between 0.56 - 0.62. Conclusions : This study suggested that occurrence of hazardous impact(ie. increased blood pressure) through lifetime lead exposure would be expected, and that the Monte-Carlo simulation was useful for the fields of occupational health.

This study investigates the differences between purchasers and non-purchasers of naturally dyed-products in the hobby/leisure, media exposure, usage of media program type, and information sources about naturally dyed-products. Data were collected from a total 213 Korean females ranging from 20 to 59 years old, and in data analyses, there were partially significant differences between the two groups. Compared to non-purchasers of naturally dyed-products, Purchasers of those ones were more interested in traditional fields and nature. They are also more exposed to newspapers and less exposed to TV. Purchasers used more informational and educational programs as well as personal and commercial information sources (store visual presentations and sales persons) than non-purchasers. However, the differences between these two groups were not significant in the interests of fashion/cooking and sports, Internet exposure, entertainment programs and public/commercial information sources about naturally dyed-products. Marketers can use the results to access the market of naturally dyed-products for promotion.
