In this study, we analyzed the needs of open university students for e-textbooks by conducting focus group interviews (FGIs) and surveys in order to develop an e-textbook that is suited to their needs. The FGIs revealed that readability and portability of e-textbooks were the most important features for students. The surveys showed that of the 276 respondents who participated in the study, only a small number owned smartpads; however, a sizeable number of students intended on purchasing the device in the future. In addition, students' smartpad utilization, time spent reading e-books, and time allotted for studying as opposed to leisure and commercial use of social network services on the smartpad were examined. Students attached importance to the portability, weight, and price of the e-textbook; moreover, they considered the device's ability to support interaction in a variety of ways and rich multimedia resources to be an advantage. Finally, students also felt that e-textbooks should be less expensive than print textbooks; however, they were willing to pay a higher price, depending on the quality of the content.

A distributed watershed model CAMEL(Chemicals, Agricultural Management and Erosion Losses) was applied to a part of grazing grassland and vegetation buffer strip(VBS) located in Daegwanryeong, Korea. A set of scenario analyses was carried out for grassland and VBS with various combinations of VBS widths, soil textures and ground surface slopes. The simulation results indicate that annual direct runoff decreases with wider VBS and the removal efficiency of pollutants generally decrease with steeper slopes. The removal efficiency of sediment is not significantly different with VBS widths. For gentle and medium slopes($10^{\circ}$, $20^{\circ}$), the removal efficiency of TOC and TN is not significantly different with VBS widths. As for a steep slope($30^{\circ}$), however, the removal efficiency of TOC and TN increases with narrower VBS. The removal efficiency of TP is generally high except for medium and steep slope of sandy loam where the removal efficiency of TP increases with wider VBS. This result of TP is contrary to the results of TOC and TN due to the adsorption characteristics of phosphorus associated with fine sediment particles. It is expected that CAMEL can be used for evaluating the effectiveness of VBS to reduce non-point source pollution discharges.

This study was conducted in order to identify factors affecting opinions on marriage of unmarried women in their 30's in Korea. Analysis of data on 529 unmarried women in their 30's, which were taken from the 2012 social survey, was analyzed. Data were analyzed using ${\chi}^2$ test, hierarchical logistic regression analysis as well as descriptive statistics by SPSS version 20.0. Results showed that age(Exp(b)=.90,p=.025), opinions on divorce(Exp(b)=3.81,p<.001) and remarriage(Exp(b)=3.09,p=.001), and value on marriage(Exp(b)=.80,p<.001) were independent predictors of opinions on marriage. Economic activity(Exp(b)=19.58,p=.003) was found to be an independent predictor of opinions on marriage for the 35-39 year old women differ from 30-34 year old women predictors. Findings of this study indicate a need for developing family and marriage value-centered education and the low-fertility policy for the 35-39year old actively working women considering factors affecting opinions on marriage.

This study examined how consumers in their 20s and 30s perceive luxury goods, masstige brands, and counterfeits, which have high social value, and whether the propensity for conspicuous consumption and conformity can explain them. Consumers were classified based on the similarity of attitudes toward these brands and purchase intentions. The groups were compared on the sub-dimensions of conspicuous consumption and conformity. Clustering analysis identified four groups, and the MANOVA result confirmed the differences among the groups. Personality (F=4.282, p=.006) and brand orientation (F=23.178, p=.000) were positively related to luxury and masstige brands. Fashion orientation (F=8.376, p=.000) was high for both groups, which likes luxury and masstige brands very much, and which likes counterfeits. High-price orientation did not make any significant difference among the groups. Conformity (F=3.537, p=.015) was high for all the groups, except for the group that liked luxury and masstige brands and did not like counterfeits. This study comprehensively examined the attitudes and purchase intentions of luxury and masstige brands and their counterfeits and can be the groundwork for further research on brand categorization.

With rapid development of technology for strong AI chatbot, the role of chatbot has been extended from conducting simple tasks to being a friend or counsellor. For this newly emerging purpose of chatbot, endowment of personality is important to make the chatbot regarded as a human being. Nevertheless I found that there are few guides about it. Thus, this study identifies the proper personality of chatbot depending on the purpose of services and user types. The purposes of chatbot services are divided into three types such as leisure-time, counselling, and task. The DISC theory is used for categorizing personality, which consists of 4 types such as dominance(D), inducement(I), submission(S), and compliance(C). An interview and survey were conducted to investigate the preferred personality of chatbot and contents for leisure-time. As results, people tend to prefer people-oriented types such as I, S for their leisure time, task-oriented types such as D,C for their task, and slow types such as C,S for counselling. Women prone to prefer neutral gender except for counselling and men tend to prefer female in all chatbot services. Preferred chatbot age is either same or younger age for leisure-time, same or older for counselling, and 30's for tasks. Preferred contents for leisure-time are mostly recent information but many 20's want fun contents and 50-70's want emphatic conversation. 30-50's want honorific but 20's and 60-70's don't care. The research results useful guide on proper personality of AI chatbot for each purpose of its service.

This study was intended to collect the baseline information on health status, nutrient intakes and dietary self-efficacy according to the obesity levels of male workers. Nutrient intakes of 224 male workers were assessed by 24 hr recall method; also, dietary attitude and dietary self-efficacy were investigated by self-administerd questionnaires. Biochemical characteristics such as blood pressure (SBP, DBP), total cholesterol(TC), hemoglobin (Hb), blood glucose (BG), SGOT, SGPT and ${\gamma}-GTP$ were assessed. Subjects were divided into normal, overweight and obese groups by body mass index (BMI). The health status was analyzed as normal group, health concerned group and disease suspected group. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio were high in the order of obese group, overweight group and normal group. Body fat mass was high also in the order of obese, overweight and normal group. Blood pressure (SBP, DBP) was the highest in obese group. SGOT, SGPT, ${\gamma}-GTP$ were higher in the obese group than normal and overweight groups. It was Proven that the percentage of those evaluated as low nutrient intakes were 71% for Ca, 50.9% for Zn, 70.5% for vitamin B2, 56.3% for vitamin C and 81.3% for folic acid. The dietary attitude scores were high according to the dietary self-efficacy. The age was positively correlated with dietary attitude, and the dietary attitude was positively correlated with dietary self-efficacy and total energy intakes. Dietary attitude showed the greatest total causal effect in relation to dietary self-efficacy. The results of this study showed some health problems and nutritional problems, indicating the need for nutritional management for male workers.
