  • Agricultural workers who mix/loads and spray pesticide in fields expose to pesticide through dermal and inhalation routes. In such situation, exposed amount should be measured quantitatively for reasonable risk assessment. Patch, gloves, socks and mask will be good materials for monitoring for dermal exposure while personal air monitor equipped with solid adsorbent and air pump will be a tool for inhalation exposure. For extrapolation of absorbed amount in dermal exposure matrices and of trapped amount in solid sorbent to total deraml or inhalation exposure, Korean standard body surface area and respiration rate were proposed in substitution of EPA data. Important exposure factors such as clothing and skin penetration ratio of dermal and inhalation exposure were suggested based on Spraying time for exposure monitoring must be long enough that the amount of pesticide to get absorbed/trapped in exposure matrices results in reasonable analytical value. In domestic case for the both of speed sprayer and power spray machine, spraying time of 20~40 minutes (0.1~0.2 ha) will be reasonable per single replicate before extrapolating to 4 hours a day with triplicates experiment.

  • This study was designed to find out the determinants of types of bullying behavior, and the effects of types of bullying behavior on the bullies. For this purpose, a hypothetical model which explains the relationships among 6 environmental factors, 5 types of bullying behavior, and 5 outcome variables for the bullies was developed. Using the data collected from 177 junior and high school students who have bullied the other students, the hypothetical model was tested. For data analysis, a path analysis was used, and the best-fitting model was found (df=78, GFI=0.953, CFI=1.00). As a result of analyzing the model, types of bullying behavior were found to be determined by the different environmental factors: Isolation was determined by 2 factors (feeling of isolation from friends, exposure to bullying), social bullying by 2 factors (lack of support from parents, exposure to bullying), verbal bullying by conflicts with parents, physical bullying by 3 factors (lack of support from parents, exposure to isolation and exposure to bullying), and instrumental bullying by lack of support from parents. On the other hand, the pleasure that the bullies feel after bullying behavior was increased by isolation, verbal bullying and physical bullying, while decreased by instrumental bullying. Guilt feeling was decreased by isolation and instrumental bullying, while increased by physical bullying. Isolation increased the tendency of blaming the victim. Isolation and instrumental bullying increased bullies' self-esteem, while social bullying decreased self-esteem. Verbal bullying increased the extent of bullying, while instrumental bullying decreased the extent of bullying. Based on the findings, the intervention strategies to change the bullies' attitudes toward victim, and to increase social support from the significant others as well as the effective ways to reorganize the school environment in order to reduce and prevent bullying behavior were suggested.

  • The purpose of this study was to examine the differences of appearance management behavior and body exposure attitude according to sex role identity. The method of this study was a survey research method by questionnaire. The subjects were 632 college students (male: 302, female: 330) living in Seoul area. The data were analyzed by SPSS program. Analysis methods used were frequency, factor analysis, Cronbach's $\alpha$-reliability coefficient, one-way ANOVA and Duncan's multiple range test. The subjects were divided into 4 types of sex role identity: androgynous, masculine, feminine, and undifferentiated type. The female androgynous group had skin care the most, while the male androgynous type had clothing management and weight control the most among the 4 types. Both male and female androgynous groups had hairstyle care the most. Both the male and female masculine groups wore chest exposing clothes the most, while the female masculine type wore shoulder exposing and leg exposing clothes the most. The female androgynous group showed the highest appearance management expenses.

  • 현재 다양한 인터넷 콘텐츠들에 의해 많은 정보가 공유되고 있으며, 유익한 정보들과 더불어 성인물과 같은 유해한 정보들이 있다. 이로 인하여 여러 문제점들이 야기되고 있으며, 이를 해결하기 위해 다양한 방법들이 제안되고 있다. 그 중에서 성인 영상 차단을 위한 연구도 많이 행해지고 있으며 주로 색상을 이용한 방법을 사용하고 있다. 그러나 살색과 유사한 영상이나 노출이 심한 영상에는 성인 영상 검출의 신뢰성이 떨어지는 단점을 갖는다. 본 논문에서는 이런 문제점을 해결하기 위해 새로운 성인 영상 차단 방법을 제안한다. 기존의 제안된 살색 검출을 이용한 방법을 기반으로 성인 영상물로 판정될 수 있는 신체 부위를 검출함으로써 강인한 성인 영상 차단을 한다. 신체 부위에 대한 판별을 위해 여러 기저 영상에서 특징 벡터를 추출하고. 이 벡터를 Back Propagation(BP) 신경망의 데이터로 이용하여 학습한다. 제안한 성인 영상 차단 방법의 성능을 여러 장의 살색과 유사한 색상의 물체 영상과 노출이 심한 영상, 성인 영상을 이용한 종합적인 실험 결과인 성인 영상 검출률을 통해 증명한다.

  • The purpose of this research was to identify the dimensions of modesty and immodesty in dress and to examine the differences in female college students' perceptions, in various cultures, of modest and immodest clothes. The researchers selected South Korea and the United States for the cross-cultural comparison study because these two countries show distinctive cultural characteristics. This study was conducted through both qualitative and quantitative methods. According to the result of the preliminary study, 47 questions were developed. The 4 Likert type scales used in the questionnaire were written in both English and Korean. Pretests were performed simultaneously in both countries. 174 American and 208 Korean students completed the questionnaire. The data were analyzed using SPSS. According to the results of factor analysis, there were 4 factors identified for the modesty-immodesty concept, including 'Conservativeness', 'Body exposure', 'Social appropriateness', and 'Attracting attention from others'. Students answered that they liked to wear conservative and socially appropriate dress in both cultures and that they did not like to wear clothing which draws a great deal of attention to them. Cultural differences were also identified. Based on the results, American students dressed more conservatively than Korean students, while Korean students preferred to wear revealing dress. American students were more conservative and preferred modest clothing. Also Korean students were more open about their body exposure and had immodest clothing attitudes.
