This study was conducted to determine the cost of production of semen and the rate of conception for artificial insemination in eight randomly selected districts of Bangladesh. A sample of 640 adopting farms were investigated. Results indicate that the cost of liquid semen per dose on full-cost and cash cast basis were Tk. 16.17 and Tk. 14.48, while the cost of locally produced exotic semen and imported semen were Tk. 31.25 and Tk. 110.00 respectively. The cost of liquid semen per insemination, per conception and per progeny on full-cost were Tk. 26.65, Tk. 50.64, and Tk. 56.27 respectively and on cash cost were Tk. 23.88, Tk. 45.37 and Tk. 50.41 respectively. The average cost of semen paid by the farmers was Tk. 14.00 and it was higher in urban areas than in rural areas. Out of the cost of A.I. centres, government had subsidized 92.16 percent and the rest 7.84 percent accrued as returns. About 40 percent of the produced semen was lost in the system which could not be used at all. The conception rate on first insemination was 53.6 percent. The rate increased to 73.2 percent upto the last insemination. The difference in conception rate between liquid semen (69.97%) and frozen semen (70.48%) was not statistically significant.

The aim of this study is to empirically identify the differentiating characteristics of determinant factors on sing-person households' commuting mode choice compared to multi-person households' one in order to establish the customized police directions to decrease private car use in commuting. While the study use the 2% sample survey data on the population and housing in 2015, it employ multinomial logit models on relative choice probability of such alternative commuting modes as bus, subway or rail, and walking, rather than driving. As potential determinant factors, the study employs demographic, socio-economic, and housing and residential one for both models of single-person and multi-person households. The study finds that the behavior of commuting mode choice has distinctive difference by gender, marriage status, physical activity constraint, job type, residential period in current housing of the single-person household's workers compared to the multi-person households' ones. Based on the findings, the study deduce ten commuting policy directions customized for the single-person household.

The purpose of this study was to investigate the effects of socio-demographic variables, adult attachment and emotion regulation style on psychological well-being of university students. We conducted a survey on 318 university students in Cheongju-si and Hongseong gun. T-test, Pearson' productive correlation, hierarchical regression analysis were used. The results were as follows: First, there was a significant difference in emotion regulation style according to university student's sex. In other words, females used more support-seeking style than males did. Second, male university students' psychological well-being was high at more active style, less anxiety attachment and avoidant/distractive style, older students, less avoidance attachment, and higher economic status. Third, female university students' psychological well-being was high at less avoidant/distractive style and more active style, older students, less anxiety attachment, and more support-seeking style. In conclusion, emotion regulation style was the strongest factor to increase university student's psychological well-being among other variables. The implications and limitations of this study were discussed.

This study is intended to investigate the demographic characteristics and socio-economic status of students, and to reveal the correlations between food habit and health condition by Todai health Index. The results of this study were summerized as followes: 1) the sex ratio of the subjects was 309 males: 129 females. Mean score of the food habit was 7,56 in males and 8.88 in females. The subjects were included in Fair and Poor group generally. Food habit score of students living their own home were significantly higher generally. Food habit score of students living their own home were significantly higher than those of the others (Lodging & Relatives, Self-Boarding, Dormitory, and so forth). 2) In males and females, mean of height and weight were 171.6cm, 62.1kg and 159.9cm, 50.9kg, respectively. Though there was insignificant difference in the physical index according to food habit score in general, there was a special trend in case of male that the higher food habit score they have, the higher physical index they get. The subjects with low food habit score showed the higher THI point in Life-irregularity, Straight-forwardness, depression and Sufferings than those with high food habit score. The female subjects with high food habit score showed the lower THI point in depression, on the contrary, showed higher in vanity. There was significant correlation between instant food, drinking and smoking and THI point.

This study identified the characteristics of the subculture aspects that led to the success of luxury brands and analyzed the implications of those aspects. For this, semantic analysis in a socio-cultural context was performed. Additionally, this study took the theoretical background, the change in subculture and post-subculture, the digital youth generation, and the change in the meaning of subculture style into consideration. The subculture style aspect and its meaning in luxury fashion brands were analyzed as follows: First, there are challenges that betray the legitimacy or values of luxury brands. Through this, the brand gained recognition and increased sales, and the designer gained a reputation as an innovative creative director. It can be seen that more successful branding was promoted by securing a more subcultured fandom. Second, by combining subculture image fragments, these brands cater to the diverse tastes of a myriad of subcultures. This maximizes commercial profits. Third, most promotional marketing activities are collaborative and done digitally, which allows for a wider customer base, but the difference is in digital capabilities. Limited editions or application use on social networks can act as another driver. It is said that the distinction in high-priced luxury brands is not only driven by economic power but also by sub-cultural capital and digital ability.

이 연구는 현재 한국의 정치사회여론조사에서 쓰이고 있는 표집틀 설정과 표본추출방법의 문제점을 지적하고 이로 인해 발생하는 여론조사의 비정확성에 대해 논하고자 한다. 현재 한국의 여론조사기관에서 가장 보편적으로 쓰이고 있는 표본추출방법은 KT에서 제공한 전화번호부에 등재되어 있는 번호를 표집틀로 사용하는 것이다. 이러한 방법의 문제점은 전화번호부에 등재되어 있지 않은 전화번호들은 표본추출작업의 초기부터 제외된다는 것이다. 이 제외된 번호들과 등재된 번호들 간에 사회인구학적 또는 정치경제학적으로 구조적인 차이가 존재한다면, 전화번호부에 등재되어 있는 전화번호들만을 대상으로 표본을 구축하는 방법은 한국의 전체 성인 인구라는 모집단을 적절히 대변하지 못하는 문제점이 있다. 2011년 1월에 발표된 아산정책연구원의 데이터를 통해 분석한 결과, 전화번호부에 등재된 번호들과 등재되지 않은 번호들 간에는 사회인구학적, 정치경제학적인 차이가 엄연히 존재하며, 이는 대통령 지지도나 정당 지지도에도 영향을 미치는 것으로 나타났다. 본 연구에 따르면, 전화번호부에 등재된 표본은 등재되지 않은 표본에 비해 친한나라당적인 태도를 보이며 대통령 지지도도 높게 나타나는 것으로 나타났다.

The objectives of this study were to analyze nutrition-related problems and to develop the nutrition education programs for high school students A survey was conducted with 500 students in the second grade level at high schools in Daegu who differed in socio-economic characteristics. In addition, body composition analysis was accomplished by the Inbody 3.0. The developed questionnaires were distributed and 481 questionnaires were collected with a 96.2% of response rate. Statistical data analysis was completed using SPSS WIN(ver.12.0) for descriptive analysis, reliability analysis, factor analysis, t-tests and $X^2$-tests. We first analyzed students' problems related to nutrition and environmental factors. In a question addressing skipping breakfast, only 11.5% answered they "do not eat" breakfast. In regards to BMI, the male students' degree of obesity was higher. Second, we analyzed living environments, which greatly influence dietary behavior. For the snacks-related categories, most of the students liked bread, cake and other snacks. When they chose the snacks, they mainly considered taste. There were significant difference among the males and females(p<.01) in terms of snacks intake habits, where 43.1 % of the males answered they snack "occasionally" and 43.4% of the females answered they snack "according to how they feel". In the case of beverages, the males consumed significantly more(p<.001). Based on their regional groups, the area A group preferred milk and milk products, and the area B group preferred soft drinks. As for the time of beverage intake, 77.6% of the females answered "with snacks", which was significantly higher than 61.4% of the males(p<.001), 12.2% of the males drank beverages after exercise. For late snacking, 68.0% of the male students and 71.1 % of the female students consumed late snacks. Most of them preferred bread, cake and other snacks. The reasons for taking a late snack were "when I feel hungry" by 61.8% of the males which was higher than the females(p<.001), 23.6% of the females consumed late snacks "impulsively". Ideally, in order to improve the food habits of high school students effective and practical nutrition education programs that consider gender and regional school group, should be carried out.

Objectives : Polymorphisms of genes from glutathione Stransferases (GSTs) and N-acetyltransferase 2 (NAT2) have been associated with increased susceptibility to various cancers. Previous results showed that East Asians such as Koreans, Japanese and Chinese have a much higher frequency of the GSTM1 and GSTT1 null genotypes and NAT2 rapid acetylator type. Therefore, we investigated the association between the polymorphic types of GSTs (GSTM1, GSTT1, GSTP1) and NAT2 and the incidence of gastric cancer which is one of the most prevalent cancers among the East Asians. Methods : It was performed in a case-control study consisting of 238 healthy subjects and 108 cancer patients (54 distal and 54 proximal carcinomas). We also evaluated the association between GSTs and NAT2 and the risk factors for gastric cancer such as alcohol consumption, smoking, H. pylori infection, family history of gastric cancer, and tumor location. Results : In our study, the percentage of cases whose hometown was rural was higher than those of controls (odds ratio (OR) =2.88; 95% CI=1.72-4.76), and the frequency of the lower socio-economic status increased significantly in patients (OR=2.53; 95% CI=1.59-4.02). There was no significant difference in the GST polymorphic types between the cases and controls. However, NAT2 rapid or intermediate acetylator types were frequently detected in the cases with family history of gastric cancer (OR=1.92; 95% CI=1.79-26.0). Conclusions : These results suggest that the hometown and socio-economic status are important environmental factors for gastric carcinogenesis, and NAT2 polymorphic types could be associated with familial gastric carcinoma.
