기판 크기가 유한하면 두 패치안테나간의 상호결합은 기판 가장자리에서 회절되어 들어오는 표면파에 의해 영향을 받는다. 상호결합이 최소가 되는 패치안테나 중심과 기판 가장자리까지의 거리는 접지된 기판의 유효 유전상수에 의해 결정됨을 알 수 있었다. 상호결합이 최소화되는 기판 크기는 이미지 방법을 사용하여 쉽게 계산 할 수 있다. 이미지 방법으로 계산한 최적화된 기판 크기와 전산모의 결과로 얻어진 최적화된 기판 크기가 잘 일치하였다.

There are three major international agreements governing mutual recognition of engineering qualifications and professional competence of the International PEs; namely, Washington Accords, APEC engineer agreement and EMF agreement. International Organizations of APEC Engineer Coordinating Committer and Engineers Mobility Forum established international registries with the goal of improving international mobility. APEC and EMF membership requires minimum qualifications for licensure with the minimum standards including engineering education, Professional experience, compliance with home jurisdiction requirements, having verified record of responsible charge, and demonstrating a commitment to continuing education.

The purpose of this paper is to study a relationship between alliance success factors and performances of strategic alliance. In order to achieve the purpose of this research, factor analysis, reliability and validity and regression method are used. In conclusion, alliance success factors can be divided as mutual complementarity and information sharing factor, sharing and mutual agreement of vision and goal factor, performance management factor and culture and organization factor. According to regression results, all of four factors affects significantly dependent variables. Among them, mutual complementarity and information sharing mostly affects each dependent variable.

본 논문은 구형 마이크로스트립 안테나의 H-plane 상호결합에 관한 연구이다. 두 안테나의 상호결합을 계산하기 위해서 단일 마이크로스트립 패치의 교사저항을 구하였으며 결합된 전송선로를 even mode와 add mode로 분발하여 각 mode의 특성저항와 실효 유전률을 계산하였다. 이로부터 자계적으로 결합된 안테나를 S-band 주파수에서 S-parameter를 구한 결과 이론치와 실험치가 거의 일치함을 확인할 수 있었다.

본 논문에서는 안전하고 효율적인 홈 네트워크 서비스를 제공하기 위해 경량화 된 상호인증 프로토콜을 제안한다. Lee 등은 공개키 연산을 이용하여 홈네트워크 상에서 속성기반의 인증된 키 교환 프로토콜을 제시하였다. 이 프로토콜에서는 전 방향 안전성을 제공하고 있으나 티켓을 이용한 두드러진 연산의 오버헤드를 줄이지는 못하고 있다. 따라서 제안하는 프로토콜은 해시함수와 카운터만을 이용하여 효율성과 안전성을 제공했다. 또한 세션키 생성후에는 사용자의 가전 제어 레벨을 체크함으로써 안전한 홈 네트워크 서비스를 제공할 수 있다.

The investment agreement prepared at the beginning of inter-Korean economic cooperation in 2000 can be evaluated as very ineffective as a product of mutual political and diplomatic compromise rather than an effective protection for our investment assets. South Korean companies suffered a lot of losses due to the freezing of assets in the Geumgang mountain district and the closure of the Kaeseung Industrial Complex, but they did not receive practical damage relief due to institutional vulnerabilities. Currently, North Korea is under international economic sanctions of the UN Security Council, so it is true that the resumption of inter-Korean economic cooperation is far away, but North Korea's human resources and geographical location are still attractive investment destinations for us. Therefore, if strained relations between the two Koreas recover in the future and international economic sanctions on North Korea are eased, Korean companies' investment in North Korea will resume. However, the previous inter-Korean investment agreement system was a fictional systemthat was ineffective. Therefore, if these safety devices are not reorganized when economic cooperation resumes, unfair damage to Korean companies will be repeated again. The core of the improved investment guarantee system is not a bilateral system between the two Koreas, but the establishment of a multilateral system through North Korea's inclusion in the international economy. Specifically, it includes encouraging North Korea to join international agreements for the execution of arbitration decisions, securing subrogation rights through membership of international insurance groups such as MIGA, creating matching funds by international financial organizations. Through this new approach, it will be possible to improve the safety of Korean companies' investment in North Korea, and ultimately, it will be necessary to lay the foundation for mutual development through economic cooperation between the two Koreas.

In this paper, E-plane gap-coupled rectangular microstrip antennas with parasitic elements are analyzed. The mutual coupling between the radiating edges is represented as the voltage-dependent current source. The gap coupling between the patch and parasitic element is characterized with the REC(Radiating Edges-Coupling) model, and the conventional transmission line model is used to obtain the equivalent circuit of the antenna. The return loss of the rectangular microstrip antennas with short-and open-circuit parasitic elements are calculated and compared with the measured values. The theoretical values including the mutual coupling are more in agreement with the measured values than the calculated values without the mutual coupling.

This study researches the dwelling satisfaction about apartment remodeling by inspecting ten apartments located in Gwang-Ju, Jun-Nam province. The method of study is to use the field study method, which is based on cultural anthropology, and the participant observation method at same time. According to the research, we find those things as they follow. First, the participation of residents and the mutual agreement are necessary in the process of the selecting a company. Furthermore it's hard to solve the problem about an uniform design and an inferior construction. These things are the most serious factor in dissatisfaction of resident environment. Second, the space of storage and veranda should be separated for the proper functions and the space for laundry is necessary. The rooms, except bedroom, and the bathroom in the main living room should be used for practical application because they are not used so often and if we make the veranda as a inner space, we've got to make a gardening plan, too. Through this research we find out that the participation of an expert company and residents for enough communication and mutual agreement and the space plan for the satisfaction of occupants are necessary for the proper apartment remodeling.

Climate change has been identified as one with the greatest challenges facing nations, government, business and over future decades. Activities to reduce greenhouse gas emissions by the Kyoto Protocol, the international community has been in progress. Korea also has introduced the Emission trading system to reduce greenhouse emission from the supervision of the government. Greenhouse gases emissions quantity should be internationally recognized. Mutual Recognition Arrangement should be recognized as the same greenhouse gas emission. International recognition of domestic verification body of international mutual recognition is required. Efforts are needed to secure the equivalence between the emission rights through direct cooperation with the relative nation accreditation body. Early entry into the IAF/PAC GHG MLA is essential for demonstrating equivalence between greenhouse gas emissions. Emissions trading will also require connection to the EU ETS, California, USA, and Tokyo, Japan to link Emissions trading. In the case of establishing accreditation standards and accreditation criteria, it will be necessary to distinguish between the domestic Energy Target Management System and the Emission Trading System. Independent greenhouse gases verification bodies should be established to meet the requirements of IAF and PAC. It is necessary to revise the qualification criteria for the verification of the greenhouse gas verification body according to international standards requirements. It is necessary to support the role of accreditation bodies of domestic greenhouse gas verification bodies. It is required to join international organizations of international mutual recognition of international trade and the need for pilot projects to link greenhouse gas emissions. The core link to our emission trading system is called EU-ETS, and we will need to join the IAF/PAC GHG MLA GHG. The International Mutual Recognition Agreement (IAF) is expected to allow international interoperability of GHG emissions verification between EA and the PAC. By signing a PAC GHG MLA, it will need to be prepared to prepare for the pilot project to link the emission trading system.

본 연구에서는 중국 시청각서비스분야의 무역장벽의 현황을 파악하고, 향후 FTA와 같은 제도적 채널을 통해서 중국측에 제기할 수 있는 통상장벽 해소를 위한 의제를 도출하였다. 먼저 중국의 시청각서비스분야의 무역장벽은 중국의 양허표와 국내 규제를 분석하여 도출하였으며 이를 토대로 설문조사를 통해 협상 의제의 중요도와 의제의 협상 타결가능성을 평가하였다. 분석 결과, 먼저 한국의 국민경제적 상황과 중국의 무역장벽 환경을 고려할 때, 중요한 의제는 온라인 게임서비스의 직접 서비스 제공과 방송/영화산업의 공동제작협정 체결이었다. 둘째, 실현 가능성 측면에서는 공동제작협정이 가장 높았으며, 다음이 온라인게임의 직접서비스 의제, 음악서비스 의제 순으로 나타났다. 시청각서비스분야 공동제작협정은 방송 및 극장에서의 외국 콘텐츠 상영에 대한 각종 규제가 많기 때문에 공동제작물에 대해 쌍방이 자국물로 인정해 주게 되면 통상장벽을 실질적으로 낮추는 효과를 볼 수 있을 것으로 기대된다. 또한 온라인게임서비스의 중국시장 진출이 가장 산업적 영향이 큰 것으로 파악되었다.
