  • 새로운 공정 기술의 발달로, 임베디드 시스템을 구성하는 하드웨어와 소프트웨어의 복잡도는 나날이 증가하고 있다. 그 결과로, 현대의 복잡한 반도체 디자인을 전통적인 HDL을 사용한 방식으로 수행한다는 일은 점점 어려워지고 있다. 본 고에서는 SystemVerilog를 기반으로 하는 새로운 시스템 수준의 설계 방식을 적용하여 실제 회로에 구현한다. 기존에 구현한 타원곡선 암호화 엔진을 재사용하여, 시스템 레벨에서 객체 지향 개념을 살려 추상화하고, 이를 이용하여 타원곡선 암호화 서버 팜을 구현한다. 전체 시스템을 하나의 통합 설계 환경에서 성공적으로 구현하여 불필요한 노력과 시간을 50%로 축소하였다. 기존 방법으로 했다면, 하드웨어 설계에 Verilog, 시뮬레이션에 C/SystemC를 사용하여 설계와 검증에 여러 단계의 시간과 노력이 필요했을 것이다.

  • In this study, we conducted a shake table test to verify the seismic performance of the paneling system with steel truss composed of bolt connections. The control group was set to the traditional paneling system with steel truss connected by spot welding method. Test results showed that the bolted connection type paneling system has excellent deformation capacity without cracking or brittle fracture of the steel truss connection parts compared to the welding type paneling system. Furthermore, in the bolted connection type, slight damage occurred at the time of occurrence of the same story drift angle as compared with the existing method, it is considered that it has excellent seismic performance. In compliance with the performance-based design recommended for the current code (ASCE 41-13) on non-structural components, it is judged that in the case of the bolted connection type paneling system, it can be applied to all risk category structures without restriction. However, in the case of traditional paneling system with spot welding method, it is considered that it can be applied limitedly.

  • 반도체 제조공정의 발전으로 새로운 기술에 대한 수요가 증가하여 임베디드 시스템을 구성하는 하드웨어와 소프트웨어의 설계 복잡도는 나날이 증가하고 있다. 그 결과 전통적인 설계방식으로는 현대 사회가 요구하는 복잡한 정보기기를 설계하기에 한계에 다다랐다. 본 논문에서는 SystemVerilog의 한 종류를 사용하여 맨-파워를 획기적으로 줄이면서 복잡한 하드웨어를 설계하는 새로운 방식을 소개한다. 새로운 설계방식에서는 객체 지향 구현을 바탕으로 하며, 이를 적용하여 기존의 이종 곱셈기 IP를 기본 블록으로 하는 복잡한 이종 곱셈기 서버 팜을 구현하였다. 설계는 단일 환경에서 하드웨어에서 테스트 벤치까지 구현하였다. 새로운 방식을 도입하지 않는다면 본 논문에서 소개하는 이종 곱셈연산기 서버 팜을 구현하는데 HDL 시뮬레이션, C/SystemC 검증에 많은 시간과 맨-파워가 투자되어야 할 것이다.

  • 본 연구는 전통민속마을에 대한 정체성을 고찰하고자 중국 천저하 민속마을을 대상으로 전통 민속마을의 색채적 특성을 분석하였다. 연구방법으로 한국표준색분석(KSCA: Korea Standard Color Analysis) 프로그램을 이용하여 색채를 분석하고 'I.R.I 형용사 Image Scale'을 통해 색채이미지에 대한 특성을 도출하였다. 이에 따른 연구결과로 첫째, 천저하마을의 색상 분포는 YR, R, Y, GY 계열의 순으로 나타났고, G계열과 BG계열, B계열은 전혀 나타나지 않은 반면 YR계열의 색상이 많은 것이 두드러진 특징이다. 둘째, 명도와 채도에 있어서는 전체가 중명도와 저채도에 해당하는 색채로 이루어져 있었다. 특히 상업고택에서만 고채도가 추출되었고 나머지는 모두 저채도 위주의 중 저채도의 색채로 이루어져 있었다. 셋째, KS계통색(KS Color System)의 분석 결과 대부분 어두운 색이 도출되었으며 그중에서도 어두운 적회색과 갈회색이 많은 부분을 차지하고 있었다. 넷째, 마을의 전체적인 분위기는 정적이고 딱딱한 분위기이고 점잖은 이미지로 조사되었다. 이상의 연구를 통해 전통마을의 보전 관리에 있어 추출 된 색채 팔레트를 참고하여 국가와 지역적 특색이 반영된 색채계획이 필요할 것으로 본다. 더불어 해당 마을의 문화가 반영된 색채는 보전하고 주변 환경과의 조화를 고려한 색채계획을 적용한다면 민속마을의 정체성 있는 색채 연출에 도움이 될 것으로 기대한다.

  • Purpose - It has been argued that the regulations restricting entry and opening hours of General Super Markets and Super Super Markets have not been as effective as expected. In contrast, the win-win item scheme that appeared recently has the advantage that it could raise the effectiveness of the system in that win-win items are in principle resigned on the basis of bilateral agreements. This study analyzes the win-win item agreement made between Homeplus at Hap-jung and small traditional markets to examine the practical effectiveness of the win-win item scheme. While existing literature studying the regulatory effects have concentrated on the restrictions around store entry or opening hours of large retailers, it can be said that there have been few empirical studies on the effect of win-win items agreement with large retailers. Research design, data, and methodology - Homeplus at Hap-jung made a win-win items agreement with nearby small traditional market traders in 2013. In accordance with this voluntary agreement, Homeplus started by limiting its sales to 15 win-win items. The survey was conducted through one-on-one interviews, April 14 to May 2, 2014, by a professional public opinion research agency. The interviews were targeted at small business retailers in the nearby traditional market. We divided the traditional markets near Homeplus at Hap-jung where the win-win item agreement was achieved into two groups, win-win item agreement markets and non win-win item agreement markets, to compare the performance difference between the two groups. Results - To determine the change in sales of the 15 win-win items, we examined the performance difference between the two groups using two criteria (compared with similar items, and compared to sales volume a year ago). The results show that the individual sales of win-win items in the win-win item agreement markets are more likely to increase than in the non win-win item agreement markets. Total sales volume of individual stores in the agreement markets also showed a more significant increase compared to a year ago than those in non win-win item agreement markets. Conclusions - Contrary to the existing retail regulations that have one-sided and uniform characteristics, it can be pointed out that the win-win item scheme has the effect of increasing the success of the system itself because it is done on the basis of mutual agreement between General Super Markets and traditional markets. The empirical results of this study can be said to support this conjecture. For the successful settlement of a win-win items agreement, the following points should be reviewed. First, it requires a great effort from the selection process of win-win items in order to improve the effectiveness of the agreement. Second, the existing General Super Markets customers should be introduced to the traditional markets or small shops to increase the sales of win-win items. Therefore, voluntary effort is essentially required from the traditional markets to engage customers.

  • According to the North Korean documents , North Korean government have emphasized the development of the Koryo medicine (traditional korean medicine) and encouraged the combination of the Koryo and the modern medicine. It is regarded that this attitude arose from the ruler's will toward independency in the medical field and at the same time the lack of modern medical resources . Combinations of the Koryo medicine and the modern medicine in the clinical textbooks are classified as follows: first, mixed medication of the Koryo and the modern medicine. Second, combination of the traditional acupuncture(or moxibustion) and the medication of modern medicines. Third, injection of modern medicines at acupoints. Forth, an intramuscular or an intravenous injection of the Koryo medicine. Fifth, anesthesia using Koryo medicine. Sixth, simple surgery at the acupoints. Lastly, combination of injection and the traditional therapy(eg. acupuncture, moxibustion and cupping) Despite of many achievements in the field of combined medical treatment, recent economic failure and severe famine for several years caused collapse of the health care delivery system in North Korea, and it is hard to find combined practices actually.

  • The purpose of this study is to consider activation methods of traditional markets in Jinju city through questionnaire and field survey. Research framework is summarized into two categories: physical environment and operation program. The results are as follows: 1) the gross profit on sales has been decreased continuously and the main causes of that have been recognized as insufficiency of parking lots and convenient facilities and deterioration of environment in spite of facilities modernization project; 2) consumers visited a traditional market because of proper price and reliance on goods, etc. However, they were not satisfied with the physical environment such as parking lots and resting spaces and the operation program such as cultural event and performance. In conclusion it was thought that activation methods of traditional market would be related to the improvement plan in the physical aspect such as parking lots, walkway, convenient and crime prevention facilities and in the operation program aspect such as cultural event, marketing, management consulting, information infrastructure, and delivery system.
