The study was done to provide domestic fashion multi-shops with basic information about the distribution and the promotion strategies through an investigation the marketing strategies for domestic multi-shop dealt with imported product only. Data were collected from Interview with a buyer or a staff of marketing department of Domestic Fashion Multi-shop dealt with Imported Product only. The results were as follows: For the distribution strategies, these fashion multi-shops as chosen were all placed in department stores. Their distribution channels were diverse like road shop, shop in department store and shop under direct management of department store. In case of shop in department store, it was common that the shop paid a definite commission to the department store. But S shop was managed directly by a department store as an advanced buying system that department store bought and sold goods and held themselves responsible for overstock. For the promotion strategies, these fashion multi-shops didn`t make a definite budget for advertising and publicity contrary to other one-brands. But they attached importance to visual merchandising (VMD) because they had to harmonized the concept of a shop with various brands. Also they concentrated on seasonal fashion show, management of their customers and personal sales.

Optical modeling and simulations of a recently developed light-emitting diode projection system for landscape lighting applications were performed. A commercially available illumination design software, LightTools, was employed to this end. Various imaging patterns available from the projection system were simulated and the simulated results were found to be in good agreement with measured ones.

The study was done to provide domestic fashion multi-shops with basic infomation about the product and price strategies through an investigation the marketing strategies for domestic multi-shop dealt with imported product only. Data were collected from Interview with a buyer or a staff of marketing department of Domestic Fashion Multi-shop dealt with Imported Product only. Through the study, it was clarified that these multi-shops showed a tendency to compose of promising brands, brands set a high value on unique character or technique and brands of promising designer noticed at the main collection. And they also extened their lines as a total life style shop dealt with acccessory, shoes and home collection as well as clothing. Therefore, they had to analyze their target consumer`s life style and applied this to organization of product, brands or sizing. To maintain the balance of multi-shop they bought products keeping the balance between all the brands and didn`t lose variety of concept, it was demanded to develop new brands as well. Their distribution channels had to be planned by regional characteristic that could be accepted their target consumers.

도심지 부근에서 이루어지는 암반 굴착작업의 증가에 따라 민원제기가 급증하고 있다. 이로 인해 발파설계시 안정성을 가장 우선적으로 고려하며, 그중에서도 지반진동을 제어하기 위한 노력이 필요하다. 본 연구에서는 발파진동의 전파특성을 결정하는 여러 인자들 중 발파조건인 기폭방법과 폭약의 종류에 따른 지반진동의 전파 특성을 알아보았다. 지반진동은 폭속이 작은 폭약에서 더 크게 나타났지만 진폭의 감쇠가 커서 진동이 멀리 전파되지 않는 특징이 나타났다. 기폭위치별 회귀분석 결과 중간기폭이 평균적인 진동수준이 가장 크게 나타났지만 감쇠가 커서 진동이 멀리 전파되지 않았다. 역기폭은 중간기폭보다 진동 수준은 낮았으나 감쇠가 작아서 진동이 멀리 전파하는 특징이 나타났다. Excavations by blasting in urban area have caused lots of complaints. Hence, special attentions need to be paid to controlling the ground vibrations in designing blasting for those areas. In this study, among the various parameters that can affect the propagation characteristics of ground vibrations, the effect of the priming location of explosive on the ground vibration level was studied for two types of emulsion explosives that had different detonation velocities. Three priming locations of top, middle, and bottom were considered in a charged hole. In the experiment on the effect of detonation velocity, the ground vibration caused by the explosive with a lower detonation velocity showed larger attenuation in the amplitude. The priming locations also affected the ground vibrations levels. The ground vibration level produced from middle priming was found to be larger than the other priming methods under the same blast conditions, but the attenuation of amplitude was also larger in this case. In contrast, the ground vibration level from bottom priming was not larger than the middle priming, but the attenuation was smaller so that the ground vibration was detected at a longer distance.

심음은 심장이 수축, 확장 시에 심장의 움직임과 혈류의 흐름에 의해 발생하는 음향이다. 심음은 여러 신호원으로 이루어져 있고, 매우 복잡하고 비고정적인 신호이다. 심장의 질환에 따라 심음의 소리는 다르게 나타난다. 심음을 구분하여 심장 질환의 유무를 판단하는 가장 기초적인 기준이 될 수 있다. 본 연구에서는 Support Vector Machine 기법을 이용하여 심음을 통한 심장 질환 판별 검출 알고리즘을 제안하였다. Support Vector Machine은 신경망의 한 종류이며 이진분류에서 좋은 성능을 보인다. 또한 Polynomial Radial Basis Function, Multi-Layer Perceptron Classifiers를 위한 대안적인 학습방법으로 사용된다. 이러한 특성을 사용하여 심음의 데이터들을 일정한 기준에 의하여 (+)데이터와 (-)데이터로 분리한 후, 각 데이터들을 학습시켜 최적의 데이터를 만든다. 이후 각 데이터들은 점층적인 추가 학습을 시킴으로써 적은 양의 학습 데이터만으로도 높은 분류 성능을 표현할 수 있다. 이 연구에서 제안된 SVM을 실제 심음 데이터에 적용한 실험에서 심장 질환의 유무 판별에 우수한 성능을 보임을 확인할 수 있을 것으로 판단된다.
