In this study, we have investigated highly efficient nanoscale surface corrugated light emitting diodes (LEDs) for the enhancement of light extraction efficiency (LEE) of nitride semiconductor LEDs. Nanoscale indium tin oxide (ITO) surface corrugations are fabricated by using the conformal nanoimprint technique; it was possible to observe an enhancement of LEE for the ITO surface corrugated LEDs. By incorporating this novel method, we determined that the total output power of the surface corrugated LEDs were enhanced by 45.6% for patterned sapphire substrate LEDs and by 41.9% for flat c-plane substrate LEDs. The enhancement of LEE through nanoscale surface corrugations was studied using 3-dimensional Finite Different Time Domain (FDTD) calculation. From the FDTD calculations, we were able to separate the light extraction from the top and bottom sides of device. This process revealed that light extraction from the top and bottom sides of a device strongly depends on the substrate and the surface corrugation. We found that enhanced LEE could be understood through the mechanism of enhanced light transmission due to refractive index matching and the increase of light scattering from the corrugated surface. LEE calculations for the encapsulated LEDs devices also revealed that low LEE enhancement is expected after encapsulation due to the reduction of the refractive index contrast.

Durability problems regarding shock absorbers are chronic problems of vehicles for which countermeasures are in dire need. Current investigation reviews various parameters that affect the durability of shock absorbers and aim to suggest design guideline to improve the issue. Test method attempted to enhance reproducibility by comparing field claim parts, parts resulting from accelerated durability testing at proving ground and parts from single component (item) durability testing is also introduced together.

The current Korea society, same as other advanced countries, has become a more aging society. The aging society will be a trend-actually it is a trend now, and be spreaded more in future. Since the number of aged people is dramatically increased, related facilities, such as special hospitals for the aged people, are needed more than any other times. In addition, the aging society has become urbanization. Different from the past years (when someone retires, he/she usually goes down to their hometowns which are suburban areas.), less aged people go down to the suburban areas; and more aged people stay in urban areas. Therefore, in my thesis, I will describe my research on a special hospital for aged people in urban area. Based on the research, I will design more suitable hospital for aged people in urban area.

이 논문은 역사적 선교적 관점에서 말레이시아의 화교와 말레이의 관계를 다루고 있다. 근대 말레이시아는 영국, 화교, 그리고 말레이와의 정치적, 경제적, 종교적으로 복잡한 상호관계를 통해서 서로의 이익을 추구하면서 형성이 되었다. 화교들의 경제적, 정치적 영향력의 확산은 다른 민족, 특히 말레이들의 반발을 일으키고 있다. 다민족 국가인 말레이시아는 건국 이후 하나된 말레이시아를 표방하며 민족 간의 분열을 해소하기 위해 노력해 오고 있지 만“5/13 사태”와 “신경제정책” 그리고 일련의 종교 분쟁으로 화교와 말레이 민족 간의 갈등은 계속되었다. 특히 코로나 이후 정부의 친 이슬람 정책으로 갈등의 골은 더욱 심화되는 양상이다. 그간 화교 기독교인들은 중국계나 원주민 같은 비 말레이 사역에 치중을 하였다. 화교 기독인들은 불편한 관계에 있는 말레이와 좋은 이웃이 되어야 하며 화교교회들은 공공신학을 기반으로 보다 적극적으로 국가와 사회의 공익에 관심을 가지고 영향력을 행사해야 한다. This article explores the relationship between the Chinese and Malays in Malaysia from a historical and missiological perspective. Modern Malaysia was formed through the complex interrelations among Britain, the Chinese, and the Malays and their respective pursuit of political, economic, and religious interests. The spread of Chinese economic and political influence has been causing backlash from other ethnic groups, especially the Malays. Since its foundation, Malaysia, a multi-ethnic country, has been advocating unity and striving to remove division, but conflict between Chinese and Malay ethnic groups are ongoing due to the May 13 Incident, New Economic Policy, and a series of religious disputes. In particular, the government’s pro-Islamic policy since the COVID-19 pandemic is intensifying tensions, as with the case of Ebit Lew. Chinese Christians have mainly been evangelizing non Malay people in Malaysia. Now they need to become good neighbors with Malays. In addition, Chinese churches should be more actively involved in the interests of the state and society, based on Public Theology.

UNCITRAL Working Group on Electronic Commerce held an extensive discussion on issues related to electronic contracting and prepared and revised the UNCITRAL draft convention on contracts concluded or evidenced by data message. the UNCITRAL draft convention on contracts concluded or evidenced by data message. would seem to be focused to achieve the legal certainty and predictability which may arise electronic commerce. The purpose of this paper is to raise the understanding of the convention on the electronic contracting and the related contract law by studying the contents of Draft Convention on Electronic Contracting. This study is regarding the contract law with applying UNCITRAL draft convention on contracts concluded or evidenced by data message. UNCITRAL has prepared the draft to provide the legal framework to help facilitate e-commerce. Based on the Vienna convention made in 1980. this draft reflected the UNCITRAL model law on electronic commerce, UNCITRAL model law on electronic signatures, UETA of US and UECA of Canada. This draft doesn't separate electronic contracts from non-electronic contracts by the objects of trade. but it defines electronic contracts made by the methods of trades, in other words, data message. The draft doesn't deal with such problems as ambiguity, disagreement in interpretation or resolving disputes between the parties in contracts. The draft should be subject to review, discussion and approvals of countries, before becoming unified international laws on electronic contracts.
