  • Several applications of body scanning technology have been commercialized or are currently under development. The virtual fit from 3D scans is most advanced form of virtual try-on. This article is an analysis of the comparison of user preferences for domestic versus foreign 3D virtual try-on systems. For this study, domestic i-Fashion Mall (www.ifashionmall.co.kr) and a Canadian company, My Virtual Model (www.mvm.com) were selected as the most representative online retailers that offer a virtual try-on system. The respondents were comprised of 70 Korean female college students in the age group 20-29. A five point Likert scale was used to evaluate the degree of the preference of virtual avatar and try-on images. T-test, cross table, and a chi-square independence test were conducted for data analysis. The results are as follow. 1. The representation about current looks according to each virtual fit image indicates that MVM is more accurate than i-Fashion Mall. 2. About decision confidence, respondents have decision confidence in i-Fashion Mall in the case of the avatar image; however, respondents have confidence in MVM or the fit image. 3. There were no significant differences in among waist size groups in accuracy, trust of each avatar image, while there were significant differences among waist size groups in the accuracy and trust of each virtual fit image. 4. About ease of use, respondents answered that i-Fashion Mall is superior to MVM. 5. The respondents prioritized the ‘fitting report’ of i-Fashion Mall and ‘Weight loss’ of MVM over other functionalities.

  • For the establishment of ready made Hanbok for the people in their 20's this study aims to develope Bagi-chogori pattern that revives the esthetic quality of the traditional Hanbok as well as comfortably fit the body. Direct method was used in Measuring the 33 parts of men which was selected as items needed for the analysis of the body and the development of patterns. In accordance with the body measurement and the analysis of the result the bust girth and height which has interrelation was chosen as the standard size for the development of pattern. Men's Baji-chogori(Korean traditional Jacket and Pants) which doesn't request fitness for instance we drew out a cross table by giving 5cm intervals each for breast waist hip girth and height. Size system of Baji-chogori was 4 steps. 1st was bust 95cm height 165cm 2nd was bust girth 95cm height 170cm 3rd was bust girth 100cm height 175cm and the 4th was bust girth 105cm height 180cm. In the case of Men the grouping of bodies was attempted by concentrating on the difference of the drop amount(Bust girth to hip girth), However 90% of men in their 20's showed a silhouette of an inverted triangle. Therefore attempt for an additional grouping wasn's Only calculation concerning the ease amount of items such as bust which and length was considered to enhance the silhouette of Hanbok when worn. Men's body for instance have a tendency to change to a rectangular shape as they get older. specially the abdominal girth trend to increase greatly. So study and development of pattern should be made for all age groups.

  • This thesis aimed to determine the effecting factors(eating pattern, working condition, stress, health care) that help maintain the health of the cosmetologists' digestive system and the diseases involved (acid reflux, indigestion, gastritis, constipation & diarrhea). The research methods included survey and statistical analysis. The survey was conducted on 242 cosmetologists from August 30 to October 30 2014. The data analysis included frequency, cross table, ${\chi}^2$-test, and regression with SPSS(V. 14). The results were as follows ; (1) The cosmetologists' health of digestive system and eating pattern are related. Regular and enough meal times cause less digestive disease. Acid reflux, indigestion, gastritis, constipation and diarrhea are differently related with the type of usual eating pattern, especially, instant food is not good for digestive health. (2) The cosmetologists' health of digestive system and working condition are related. Longer daily working hours and exposure time to chemical odors are more likely to be associated with digestive diseases; whereas, longer time of standing and talking with colleagues are less likely to be associated with digestive diseases. (3) The cosmetologists' health of digestive system and stress are related. Headache, boredom, conflict of pay and compensation, and insomnia are not good for digestive health. (4) The cosmetologists' health of digestive system and health care are related. Periodical medical examination and usual body stretching are correlated with digestive diseases; whereas, people who do regular exercise and bowel movement are less likely to have digestive diseases.

  • The purpose of this study was to provide basic information for developing nutrition education programs for preschool children and their families. The subjects were 291 parents whose children went to daycare centers in Uiwang. The questionnaire contained 15 items for children's dietary habits and six items for parents' nutritional attitudes. The results of frequency analysis of children's dietary habits were as follows: 63.9% of children ate meals regularly, however breakfast (46.4%) was usually skipped; 44.0% of children ate a snack more than twice per day; 56.7% did not have late night meals; 49.5% ate out once to twice per week; 89.7% had dinner with family more than three times per week; and 43.6% had picky eating habits. The percentage of children who did not eat vegetables and seaweed was the highest among other food groups. Intake frequencies were low in fatty foods, instant foods, and fast foods. Some correlations were observed between picky eating habits and other dietary habits by cross-tabulation analysis. Intake frequency of non-picky eating children was lower for late night eating and fatty foods but higher for vegetables and seaweed compared to picky eating children. Parents answered that their nutritional knowledge level was normal (72.2%), and nutritional information was collected using the Internet (36.0%). Nutritional value was the most considered point in meal preparation of parents (43.3%), and the most difficult factor in child's diet management was lack of time due to working (36.1%). Parents cited method of creating a menu (27.0%) and table manners (25.3%) as topics of nutrition education by professionals. Therefore, various nutrition education programs need to be developed to improve healthy dietary habits for children and their families.

  • Purpose - This study examined the effect of tariff cuts on productivity in Korea's manufacturing industries and the effect of initial productivity level before tariff cuts on productivity improvement after tariff cuts. We also attempted to identify whether import-driven or export-driven factors are more important for productivity improvement, especially in low productivity industries. Design/methodology - Since tariff reduction is a policy decision that can affect cross-industry, its impact is spread across all industries beyond the scope of a single firm through the input and output network of industry structure. Accordingly, we proposed a new method to measure the change in productivity to reflect the impact of tariff cuts across industries. Through an Armington CGE analysis, changes in endogenous variables can be directly measured after the exogenous shock of tariff reduction, and the amount of movements in productivity triggered by tariff cuts can also be calculated. We can thus assess the effectiveness of exogenous policy, such as tariff cuts, through the difference between the benchmark and counterfactual values of endogenous variables. Findings - This study confirmed that tariff reduction positively affected productivity improvement in Korea's manufacturing industries. It also confirmed that productivity gains occur in Korea's leading export industries. Finally, greater productivity gains were recorded in the group with additional high-export-share or high-import-share conditions for low productivity industries. These results are, in a limited sense, consistent with the existing studies that emphasize the importance of exports and imports on productivity improvement, especially for low productivity industries. Originality/value - The results of our experiments are different from those of non-CGE studies, which measure the industry-level change in productivity with dummy coefficients, in terms of directly calculating the amount of change in productivity. In addition, we propose that the Armington CGE model is more appropriate than the Melitz CGE model to directly measure the productivity after tariff cuts. This is because the Melitz CGE model assumes the given specific productivity density, which does not change after an overall drop of tariffs. To the best of our knowledge, this approach to directly calculating productivity by reflecting the impact of tariff reduction across industries through CGE analysis, is unprecedented in this literature.

  • 본 연구는 지역산림지역을 중심으로 수량화이론을 이용하여 산사태 발생면적에 영향을 미치는 인자를 도출하여 각 인자의 기여도 분석을 통해 산사태 발생 위험성에 대한 예측기준을 마련하고, 그 기준을 평가하였다. 산사태 발생지 붕괴면적에 영향을 미치는 인자는 모암(화성암), 횡단사면(복합), 침엽수림(임상), 사면경사($21{\sim}30^{\circ}$ 이상)이었다. 각 인자의 Range를 추정한 결과, 횡단사면 (0.2922)이 가장 높게 나타났고, 다음으로는 모암(0.2691), 임상(0.2631), 사면경사(0.2312)순으로 나타났다. 산사태 발생 위험도 판정표를 기준으로 4개 인자의 category별 점수를 계산한 추정치 범위는 0 점에서 1.0556 점 사이에 분포하고 있으며, 중앙값은 0.5278 점이었다. I 등급의 점수는 0.7818 이상, II 등급은 0.5279~7917, III 등급은 0.2694~0.5278, IV 등급은 0.2693 이하로 나타났다. 1 등급 및 2 등급에서 산사태 발생 비율이 72%로서 비교적 높은 적중률을 보였다. 따라서 본 판정표는 산사태 위험도 판정에 활용 가능한 것으로 판단된다.

  • 교통노면표시는 다양한 도로정보를 일차적으로 이용자에게 전달하는 중요한 교통시설 중 하나로, 교통노면표시에 대한 올바른 이해는 교통안전 향상 및 올바른 교통문화 정착에 필수적인 사항이다. 그러나 전술한 교통노면표시의 중요도에도 불구하고 교통노면표시 이해도에 대한 국내 연구결과는 미흡한 실정이다. 본 연구에서는 이용자별 교통노면표시의 이해도를 설문조사를 통해 추정하였으며, 이용자 특성에 따른 이해도 차이의 유의성을 교차표와 로지스틱 모형을 적용하여 분석하였다. 분석결과 분석대상 교통노면표시에 대한 평균 이해도는 57.41%로 비교적 낮게 나타났으며, 양보표시의 이해도가 25.88%로 가장 낮았으며, 횡단보도예고표시의 이해도는 91.18%로 가장 높게 분석되었다. 한편 교차분석결과 일부 노면표시의 이해도는 운전면허 정지 및 취소자(특별교통안전교육대상자)와 같은 이용자 그룹에 따라 유의한 영향을 받으나, 보다 일반적인 이용자 특성(성별 및 운전경력)에 따라서는 크게 달라지지 않음을 알 수 있었다(${\alpha}$=0.05). 이처럼 교통노면표시에 대한 전반적인 이해도는 이용자 특성에 따라 유의한 차이를 보이지 않는바, 모든 이용자를 대상으로 하는 전반적인 노면표시 이해도 향상 방안의 도출이 필요하다고 판단된다.
