요즘, LCD TV 가 등장하면서 LCD 백라이트로써 LCD TV 에 적용하기 위해서는 무엇보다도 휘도특성의 개선이 요구되고 있다. TV 대응 LCD Panel 은 Monitor 대응 제품에 비해서 일반적으로 해상도가 낮으므로, 투과율면에서 장점은 있으나, 현재의 백라이트 구조로는 만족할만한 성능을 낼 수 없는 상황이다. 그러므로 고휘도 백라이트를 위해서 EEFL(External Electrode Fluorescent Lamp) 혹은 CCFL(Cold Cathode Fluorescent Lamp) 의 복수 사용을 전제로 한 직하방식에 대한 개발 검토가 활발히 이루어지고 있다. 직하방식에 의한 고휘도화는 램프수는 증가되지만 프리즘시트를 사용하지 않아서 가격 경쟁력이 있다. 따라서 본 연구에서는 EEFL 16등을 이용하여 17인치 직하형 백라이트를 제작하여 기구적, 전기적, 광학적 특성을 분석하였으며, 그 결과 11,700 nit 의 휘도를 달성하여 TV 대응 수준을 확보하였다.

This study investigates differences in fashion products attributes, mobile shopping mall attributes, impulse buying behavior, and satisfaction according to mobile shoppingconsumption value. The findings provide new information on marketing strategy for mobile shopping malls. A total of 283 usable questionnaires were obtained from college students. Data were analyzed by frequency analysis, factor analysis, and ANOVA using SPSS 21.0 for Windows. The results were as follows. First, according to the consumption value, consumer were classified into 3 groups: social/functional oriented, indifference and epistemic/emotional oriented. Second, the conspicuous-functional pursuit group considered utility and exhibition more important in regards to fashion products attributes for the consumption value group, the personality pursuit group also considered aesthetics and utility more important than other groups. Third, conspicuous-functional pursuit group considered continuous management more importantin regards to the importance ofmobile shopping mall attributes for the consumption value group, the personality pursuit group considered informationexchange more important than the other groups. Fourth, the conspicuous-functional pursuit group and Personality pursuit group considered impulse purchase behavior more important than the emotionalpursuit group. The conspicuous-functional pursuit group considered satisfaction after impulse purchase behavior more important than other groups.

After the accelerated aging, the bulkhead initiator using high explosives was carried out to verify aging characteristics. The Thru-Bulkhead Initiator operates by transmitting shock-wave generated from micro-initiator to the acceptor and the ignition explosives through the bulkhead. In order to evaluate the life-time of the product, the accelerated aging condition was set according to the life-time, and the ignition performance of the sample was measured every 10 cycles by measuring the delay time and the maximum pressure through the 10cc closed bomb test. In addition, variance analysis was used to determine aging.

The purpose of this study is to propose grading increments chart for women's bodice sloper in their 20s in order to increase consumer satisfaction with apparel products. The selected bodice sloper is a compromise between the German Müller bodice sloper and the Japanese Munhwa bodice sloper. Based on National Standards Position Survey data, the main dimension average for women in their 20s was set. The grading increments was set at the grading deviation application area in bodyboard and sleeve. Thereafter grading was done and the suitability of the graded pattern was checked.

기존의 Monitor 대응 LCD 에서 TV 대응 LCD로의 개발에 있어서 특성 개선은 다각도로 진행되고 있으나, 무엇보다도 휘도 특성의 개선이 요구된다. TV 대응 LCD Panel 은 Monitor 대응 제품에 비해서 일반적으로 해상도가 낮으므로, 투과율면에서 장점은 있으나, 현재의 B/L 구조로는 만족할만한 성능을 낼 수 없는 상황이다. 고휘도 BL(Back Lignt)를 위해서 EEFL(External Electrode Fluorescent Lamp) 혹은 CCFL 의 복수 사용을 전제로 한 직하방식에 대한 개발 검토가 활발히 이루어지고 있으나, 직하방식에 의한 고휘도화는 램프수의 증가에 따른 인버터의 기구적, 전기적 사양의 증가를 필요로 하며, LCD Module전체의 두께가 증가되는 문제를 가지고 있다. 본 연구에서는 L-Shaped 램프를 적용하여 기본의 기구적인 사양 및 전기적인 사양을 유사하게 유지함과 동시에, 고휘도화를 실현하여 TV 대응 수준을 확보하였으며, lamp를 floating구동하여 램프편측 전압 500V를 사용하면서 655 nit의 휘도를 달성하였다.

The number of Japanese and Chinese tourists visiting Korea has been increasing rapidly and cosmetics is one of the most popular shopping items for tourists. The purpose of this study was to examine factors affecting the cosmetic purchase of Japanese and Chinese female tourists in Korea and compare their purchase behaviors. Questionnaires were collected from December 12, 2010 to February 15, 2011 from the tourists visiting Myeongdong and duty free shops in Seoul. 126 responses from Japanese and 163 from Chinese tourists were used in the final analysis. There were significant differences in many aspects between the two groups. Chinese tourists were satisfied with Korean cosmetics more and found them to be more favorable, and were more active in information searches than Japanese tourists except in a few aspects. Hallyu (Korean wave) had a powerful influence on Korean cosmetics purchase behavior for both Japanese and Chinese tourists, but its effect was stronger among Chinese tourists.

The purpose of this study was to investigate the effect of duty free shop consumers' store benefits sought and fashion merchandise shopping orientation on store satisfaction. Survey data were collected from questionnaires filled out by 194 domestic consumers who had purchase experience of fashion goods in duty free shops located in Korea. The data were analyzed by reliability analysis, factor analysis, and multiple regression analysis. The results of this study were as follows: First, the store benefits sought was categorized into five factors such as pursuit of convenience, salesperson/atmosphere, promotion, product quality, and product fashionability/variety. The fashion merchandise shopping orientation was categorized into six factors such as pleasure orientation, pursuit of fashion, pursuit of brand, planned orientation, pursuit of confidence, and convenience orientation. The store satisfaction was categorized into six factors such as atmosphere/reputation of store, promotion, product fashionability/variety, convenience, price, and salesperson. Second, the store benefits sought, composed of pursuit of convenience, salesperson/atmosphere, promotion, product quality, and product fashionability/variety, had an effect on the store satisfaction. Third, the shopping orientation such as pleasure orientation, pursuit of fashion, pursuit of brand, and planned orientation, with the exception of pursuit of confidence and convenience orientation, had an effect on the store satisfaction.

This study explores the attributes of the on-line shopping products and prices, and their effects on the customer satisfaction. In doing so, the sample population has been segmented according to their shopping propensity of consumption on clothing to understand the group differences. Based on the previous researches, the researcher have chosen four important characteristics of the customer's shopping propensity. The number of iteration on factor analysis revealed that the sample population can be classified into three different groups; the convenience/pleasure-seeking group, the fashion/utility-seeking group, and the unconcerned group. The significant group differences resulted on the following study variables; the product assortment, the price rationality, and the value of the price. Also, from the product aspect, the characteristic, the assortment, and the expression in order, explained the significant portion of the Y variance. While, on the aspect of price, the rationality, and information in order, significantly contributed on the customer satisfaction.

As information threats to information systems diffuse, the information security becomes a major concern. Information security manpower who produce and implement information security products, and who are in charge of information security in organizations, has been important. Korean government has implemented various policies to promote the information security manpower. Those policies have been successful to supply enough number of information security manpower, but not successful to supply information security manpower to meet the various requirements of the manpower demand. In this study we adopt analytic hierarchy process(AHP) to analyze the priorities of information security technology categories to meet the demand. Results of the study suggest that the government should concentrate on promotion of manpower for the field of the 'System and Network Security Technology'.
