디자이너라면 누구나 디자인의 결과물을 얻어내는 과정의 첫 단계로서 디자인의 컨셉을 만족시킬 수 있는 발상의 단계를 거치게 될 것이다. 그러나 새로움을 요구하는 발상은 누구에게나 노력하는 정도만큼 비례하여 얻어지는 속성을 지니고 있지 않다. 왜냐하면 인간이 노력하여 얻어낼 수 있는 합리적이고 논리적인 사고의 틀 속에는 새로운 것이 존재하지 않기 때문이다. 그러므로 좋은 발상의 핵심은 어떻게 하면 비논리적 사고영역에 자기 자신을 원하는 시간 동안 머물 수 있게 하는가에 있다고 말할 수 있다. 본고에서 제시하고 있는 "결과미리보기"의 사고법은 광고기획서에서 최종 단계에서 제시되고 있는 광고컨셉을 만족시키면서도 최종 단계에서 제시되고 있는 광고컨셉을 만족시키면서도 수평적사고의 영지에 인간의 사고활동을 일정 시간 묶어 둘 수 있는 발상모델이 될수 있다고 생각한다. 뇌기능이론에서, 우뇌나 좌뇌의 활동지수의 높고 낮음이 실제 작품제작에 미치는 영향은 유의할 정도가 아니라는 사실이 연구결과 드러났다.연구결과 드러났다.

버스트 제어 정보와 버스트를 offset 시간으로 분리하여 전송하는 광 버스트 스위칭 망에서 버스트 충돌 발생은 서비스 품질 저하를 초래하며 이러한 현상은 버스트 크기가 클수록 더욱더 심각해진다. 그러므로 노드에서 버스트 충돌 방지를 위한 효과적인 예방 대책이 반드시 수립되어야 한다. 그러나 현재 광 버스트 스위칭 망에서 제시되고 있는 버스트 충돌에 대한 다양한 접근 방법들은 버스트 충돌 발생 후 이를 해결하기 위한 방안으로 제시되고 있다. 그러나 본 논문에서 제안한 기법은 Ingress 에지 노드에서 부 반송파 다중화 기술을 이용하여 버스트 전송 크기를 줄임으로써 코어 망에서 스케줄링 시 발생할 수 있는 버스트 충돌 확률을 미리 예방하는 방법이다. 이를 위해 본 논문에서는 부 반송파 다중화 기한의 광 버스트 스위칭 망에서 버스트 생성과 전송을 위한 모듈구조와 기법을 제안하였다. 또한, 제안된 기법에 대해 파장 개수와 부 반송파 개수에 따른 버스트 손실률, 처리율 및 총 용량 관점에서 성능 평가를 실시하였다.

This study reviewed selected specific windows and reviewed the window performance certification criteria including KS F 2278 and KS L 9107 and analyzed the change in performance based on the change of area. This study also compared the heating and cooling loads of an apartment house applied with window performance reviewed in consideration of insulation and SHGC performance and actual size based on KS F 2278. The analyzed window was a double window composed of aluminum and PVC and the building was the apartment house model of 141 ㎡. The analysis results were as follows. First, as the window glass's thermal performance is superior to frame, the performance degraded in reduced area. In case of selected window, the 1 m × 1m window's thermal performance and SHGC decreased by 35% and 37% respectively compared to 2 m × 2 m window. Secondly, in the comparison of performance for increasing area with 2 m × 2 m and 3 m × 3 m windows, the 3 m × 3 m window's thermal performance and SHCG increased about 14%. Third, in the comparison of heating and cooling loads of the analyzed model considering the apartment house model applied with window performance derived from KS F 2278 and actual figures, the model's total heating and cooling loads increased by 33% with cooling decreasing by 36% and heating increasing by 77%. Above analysis results show that evaluation of window performance based on criteria such as KS F 2278 and KS L 9107 may lead to distortion of performances different from actual products. Thus, it is necessary to suggest new evaluation criteria.

This study is to find out the changes and features of male consumers' life style and purchase tendency according to the change of Korean fashion market, and based on which to suggest the design for the 20s men as well as a proper distribution channel for it. Documentary research and investigation were done together for the study. By reviewing documents focused on previous studies and declaring the change of men's fashion shopping tendencies and the following changes and features of their fashion sense and styles a conceptional frame for a design suggestion was presented. Ways to investigate were men's wear collection research, Q-technique. First of all, they tend to boldly reduce unnecessary purchases and do not hesitate to focus on the wanted item, expanding the trend of 'value purchase.' Secondly, men's wear use various design elements with feminine images, while the materials, colors and design expressive techniques that have been exclusively used for women's wear, began to be applied to men's one, turning them into gentle styles with womanhood is stressed. Thirdly, Korean distribution channel is rapidly diversified from departments to new-concept ones such as multi-brand stores. Especially, displaying and selling various optional products, multi-brand stores lead such diversification of fashion distribution channel. Fourthly, features of the drapery types favored by the 20s men are that they like no-chromed dark or blackish colors with fixed structure and partially-applied drapery on the clothes. Fifthly, it turns out that men in their 20s set a premium on design and price while they buy clothes. In addition to that, they buy clothes mainly during discount period and displayed much bigger satisfaction for the purchase on discounted price that those on normal price.

What is purchase motivation for luxury brands? and what kind of process through makes higher cult intention(i.e.,loyalty). How does consumption value affect loyalty? Theoretically, it was studied whether it could be explained. The luxury products and services were divided into categories and surveys were conducted at the national level. This research analyzed the influence of positive affect on cult intention by mediating luxury consumption value with S-O-R frame. The logic was developed with excitation transfer theory. Positive affect, compatibility mediating effect were investigated. Unlike the previous studies that have been recognized as important in terms of symbolic value in luxury brands, it was confirmed that experiential consumption value had the greatest impact. In addition, the influence of functional value and symbolic value had a significant effect. The effect of consumption value on cult intention was mediated by positive affect and compatibility. Therefore, emotional response can be seen as having an effect on cult intention through excitement transfer. These findings suggest that luxury brand marketers need to develop consumer values that can lead to arousal and positive emotional responses to suit consumer lifestyle. The research results are expected to contribute to the experience marketing and the hospitality service of luxury brands.

The structure of the Hanwoo (Korean Native Cattle) Industry remains very weak and vulnerable to the WTO/IMF system. Considering that the majority of cattle farmers are small sized, and that marketing systems are outdated and inefficient, rapid expansion of lower priced beef imports by WTO system and rapid increasing of production costs by IMF system would lead to the deprivation of a regular source of farm income and threaten the stability of rural life. Accordingly, the Hanwoo industry should be expanded in accordance with progress in the implementation of (1) programs for the structural adjustment and (2) measures to compensate for the loss. Efforts for lowering major production factor costs needs to continue, In order to increase the supply of calves at low cost, the programs of collective cow-calf farms should be expanded, thereby reducing the cost of calf purchase, which constitutes the largest share of Hanwoo production cost. Also, feedlot operations should be encouraged for small herd farms in order to achieve a substantial saving in beef production costs by integrated operations from calf production to cattle fattening. A substantial saving would also be made by collective purchase and distribution of various inputs through the cooperatives' channels. Extension services should be strengthened for cattle farm management, cattle care and feeding, prevention of cattle disease, etc. In order to minimize cash outlays for commercial mixed feeds, utilization of far by-products as feeds should be enhanced and production of forage crops productive of resources, such as land and rural labor, during the farm o(f-season, needs to be encouraged. Also, technological development for enhancing the nutritional value of farm by-products should be encouraged. Measures for successful segregation of the Hanwoo beef market should be implemented, thereby enhancing incentive for quality beef producers and protecting consumers willing to pay higher price for quality beef. For development of the Hanwoo industry, a considerable time frame would be required in order for (1) small livestock farmers to make a successful adjustment by staying in the enterprise and achieving increased price efficiency (2) livestock farmers to acquire know-how for producing quality Hanwoo beef, (3) the ongoing Government policy of enhancing price-quality competitiveness, and for improving the quality Hanwoo beef marketing to take root. (4) consumers to increase their ability to distinguish meat quality, and others.

Cytoplasmic male sterility (CMS) induced by mutant mitochondria genome, has been used for commercial seed production of $F_1$ hybrid cultivars in diverse crops. In pepper (Capsicum annuum L.), two sterile cytoplasm specific gene organization, atp6-2 and coxII were identified. An open reading frame, orf456 nearby coxII gene has been speculated to induce male sterility (MS) by mutagenic analysis. Moreover, molecular markers for atp6-2 and coxII of mitochondrial genotype (mitotype) were developed. However, the Cytoplasmic MS specific markers, atp6SCAR and coxIISCAR markers appeared in both N and S cytoplasms when polymerase chain reaction (PCR) cycles prolonged more than 40 cycles. Since the reported molecular markers were dominant markers, the presence of the faint sterile-specific band in normal cytoplasm may lead to the mis-classification of pepper breeding lines. To solve this problem, one common forward primer and two different reverse primers specific to normal coxII and sterile orf456 genes were designed after analyzing their gene organizations. By using these three primers, N and S coxII specific bands were co-amplified in male-sterile lines, but only normal coxII specific band was amplified in maintainer lines. Since the reverse primer for sterile coxII was specifically designed 275 bp downstream of orf456, relatively stable PCR amplification patterns were observed regardless of the number of PCR cycles. These primer sets easily identified different mitotypes among the divergent breeding lines, commercial cultivars and diverse germplasms.
