p-type CdTe Films that contained CdCl₂and CuCl₂were prepared by coating and sintering. For the sintered CdTe films that contained 1wt% of CdCl₂befor sintering, the electrical resistivity decreases sharply with increasing sintering temperature, and the resistivity is dependent of the sintering temperature for the sintered CdTe films that contained 1wt%, 6wt% and 11wt% of CdCl₂. This fact conbined with the observed microstructures indicate that the CdCl₂acts as a sintering aid. For the specimens which contained various amounts of CdCl₂befor sintering and were sintered at a high temperature(such as at 700℃), the microstructures are improved and the electrical resistivity increases with the amounts of CdCl₂. Therefore it can be concluded that the CdCl₂acts not only as a sintering aid but also a dopant source of donor (Cl) during the sintering measurement, it can also be concluded that all the grains are depleted of dark conductivity and C-V measurement, it can also be concluded that all the grains are depleted of carrier by the trapping centered at grain boundaries. The electrical resistivity decreases with increasing amounts of CuCl₂up to 250ppm due to Cu-doping sintering.

Modeling of Anisotropic Creep Behavior of Coated Textile Membranes

Yu Woong-Ryeol,Kim Min-Sun,Lee Joon-Seok The Korean Fiber Society 2006 Fibers and polymers Vol.7 No.2

The present study aims at characterizing and modeling the anisotropic creep behavior of coated textile membrane, a class of flexible textile composites that are used for moderate span enclosures (roofs and air-halls). The objective is to develop a creep model for predicting the lifetime of coated textile membrane. Uniaxial creep tests were conducted on three off-axis coupon specimens to obtain the directional creep compliance. A potential with three parameters is shown to be adequate for modeling the anisotropic creep behavior of coated textile membrane. Furthermore, a possibility of predicting the creep deformation of coated textile membrane in a multi-axial stress state is discussed using the three-parameter potential.

중국 위안화 금리 패리티 분석 : 엔화, 원화 및 중국 역외·역내 위안화 시장 비교분석

김웅열(Woong Ryeol Kim),김문겸(Moon-Kyum Kim) 글로벌경영학회 2019 글로벌경영학회지 Vol.16 No.3

본 연구는 SDR 국제통화로 편입된 위안화가 CIP 이론이 성립되는지 여부와 차익 포트폴리오이익이 존재하는지를 분석한 연구이다. 위안화 분석 결과는 엔화와 우리나라 원화와 비교하여 위안화의 특성을 규명하였다. CIP 이론으로 산출된 위안화 패리티 선도환율과 시장 선도환율을 회귀분석 하여 CIP 이론의 성립 여부를 확인하고 위안화와 엔화 및 원화의 차익 포트폴리오를 구축하여 차익거래 수익률을 비교하였다. 거래 비용을 감안하지 않은 경우, 엔화, CNY 중국 역내 위안화, CNH 홍콩 역외위안화 및 원화는 모두 CIP 이론이 성립하지 않는 것으로 나타났다. 그리고 위안화는 국제통화인 엔화와 비국제통화인 원화보다도 CIP 이론으로부터 더 크게 벗어나 있어 국제금융시장과 통합 정도가 약한 것으로 나타났다. 그러나 중국 중앙은행이 위안화 유동성을 CNH 홍콩 역외위안화 시장에 공급한 이후 CNH 홍콩 역외위안화의 CIP 편차와 차익거래 수익률이 축 소되어 엔화와 유사한 특성을 가지는 것으로 바뀌었다. 거래비용 감안 시 엔화 차익 포트폴리오는 차익거래의 실익이 없는 것으로 나타나 실질적으로 CIP가 성립되었으나 중국 역내 위안화 및 원화는 차익거래 기회가 존재하였다. 위안화 및 원화의 차익 포트폴리오 수익률 수준을 확인함으로써 기업이 무역거래와 자본거래에서 효율적으로 거래통화를 선택하면 차익거래 수익률만큼 비용을 절감할 수 있다는 점을 밝혔다. CNH 홍콩 역외위안화는 유동성 공급 이후 국제금융시장과의 통합정도가 증가된 것으로 확인되어 통화 국제화 초기에는 적절한 유동성 공급이 핵심요소라는 정책시사점을 제시하였다 In this study, we analyze whether RMB, which is SDR international currency, holds the CIP relationship and whether there is any profit from RMB arbitrage portfolio. We compared RMB analysis result with JPY and KRW to determine the characteristics of RMB. We regress the forward rate which is calculated from CIP theory to market forward rate to analyze whether CIP theory holds or not. We also constructed arbitrage portfolio of RMB, JPY, KRW to see if there is any difference in the yield. We found that the CIP theory does not hold for JPY, CNY onshore RMB, CNH Hong Kong offshore RMB and KRW, if transaction cost is not included. The RMB deviated more from CIP theory than JPY, which is the international currency, and KRW, which is the non-international currency. It turned out that the degree of integration of RMB with the international financial market is relatively weaker than that of JPY and KRW overall. However, after China s central bank supplied RMB liquidity to CNH Hong Kong s offshore RMB market, CNH, Hong Kong s offshore RMB CIP deviation and arbitrage portfolio return have decreased. So, CNH Hong Kong offshore RMB turned out that it has similar characteristic like JPY. There was no actual profit of JPY arbitrage portfolio when we included transaction cost. So, JPY proved CIP holds. But there was an opportunity for arbitrage profit of CNY onshore RMB and KRW. We checked the level of the arbitrage portfolio return of RMB and KRW. So, it is possible to reduce financial cost if a company selects trade and capital market currency efficiently. We also found that CNH Hong Kong offshore RMB market increased its integration with the international financial market after China central bank provided liquidity. This presented a policy suggestion that in the early days of internationalization of currency, adequate liquidity supply is very important.

한국사상(韓國思想)(사학(史學)) : 16세기 왕비(王妃) 가문(家門)의 변천(變遷)과 성격(性格)

양웅렬 ( Woong Ryeol Yang ) 한국사상문화학회 2011 韓國思想과 文化 Vol.60 No.-

본 연구는 16세기 왕비가문의 변천과 성격을 무오·갑자, 기묘, 을사사화와 선조 즉위 등 중요한 정치 상황에서 본가, 처가, 외가의 친인척들과의 연혼관계 속에서 살펴본 것이다. 중종반정 이후 훈척 가문에서 왕비를 배출하였다. 연산군대 두 차례 사화로 사림들은 화를 입었고, 갑자사화 때는 훈척세력도 적지 않은 화를 입게 되어 심온의 외손들인 박원종 등 훈척세력이 주도하는 중종반정이 일어나는 배경이 되었다. 그래서 중종대 이후에도 훈척 세력에서 왕비를 배출하고 있었다. 중종대 당시 정현왕후가 대비로 계신가운데, 대비와 같은 파평윤씨 가문에서 중종의 계비 장경왕후와, 문정왕후가 배출되고 있었다. 아울러 이런 분위기에서 세조찬탈 공신인 박강의 손자인 반남박씨 박용의 딸 인성왕후가 인종비로 오르고 있었다. 그러나 파평윤씨는 중종대 후반 대윤, 소윤 세력으로 나뉘어 서로 대립되다가 을사사화와 문정왕후의 사후 몰락하는 등 훈척 왕비 가문은 밀려나고 있었다. 한편 세종대 심온옥사로 몰락하였던 청송심씨 가문은 세조대 다시 등용되어 청주한씨와 파평윤씨가 주도하는 가운데에서도 성종대 등장한 사림세력과 연계를 가지며 큰 세력을 형성하였다. 그러다 청송심씨는 연산군대 갑자사화로 사림세력과 함께 크게 화를 입었지만 중종반정 이후 사림과 교류하며 다시 성장하였으며, 중종대 후반 대군부인(명종비)을 배출하며 세력을 강화하고 있었다. 명종대 이후 청송심씨는 사림들과 폭넓게 교류하며 사림들의 정계 진출을 돕기도 하고, 그들을 보호하기도 하며 당시를 주도하였다. 이후 사림으로부터 受學한 선조가 즉위한 이후 반남박씨, 연안김씨 등 사림가문에서 왕비를 배출하고 있었다. This study looked at the 16th century resulting through marriage by those related to the original houses, maiden houses, and maternal houses of queens during significant political milestones such as the First Literati Purge and the Second Literati Purge during the reign of King Yeongsan, the Third Literati Purge during the reign of King Jungjong, and the Forth Literati Purge during the reign of King Myeongjong and the coronation of King Seonjo. The two literati purges during the reign of King Yeonsan dealt a serious blow to the Sarim, or "forest of scholars." After the Second Literati Purge, in particular, greatly compromised the political influence of queen families and relatives, maternal political factions including Park Won-jong and the children of Sim On`s daughters led the King Jungjong Restoration. As a result, when Queen Jeonghyun of the Papyeong Yoon clan became the queen dowager during the reignof Jungjong, Janggyeong and Munjeong from the Paypeyoong Yoon clan of King Jungjong`s maternal family line, became queens to King Jungjong. Later, a daughterof Park Yong, grandson to Park Gang of the Bannam Park clan, a vassal who contributed greatly to King Sejo`s usurpation, married King Injong and was throned Queen Inseong. Near the end of the reign of King Jungjong, however, the Papyeong Yoon clan and the Bannam Park clan split into daeyoonn and soyoon factions and fought each other. After the Third Literati Purge and the death of Queen Munjeong, the went into demise. In the meantime, the Cheongsong Sim clan, which had collapsed after the Sim-on Treason during the reign of King Se-jong, restored its power during the reign of King Sejo and became a significant political force linked to Sarim, which had emerged during the reign of King Seongjong, a time when the Cheongju Han clan and the Papyeong Yoon clan wielded significant political clout. The Cheongsong Sim clan suffered a significant blow along with Sarim following the Second Literati Purge during the reign of King Yeongsan, but rose to power once again, in connection with Sarim, after the Jungjong Restoration. The clan prospered as a daughter within the clan married King Myeongjong in the latter period of King Jungjong`s reign. From the reign of King Myeongjong, the Cheongsong Sim clan remained a major political force, building an extensive relationship with Sarim, helping members of Sarim join the political circle, and protecting them. After the coronation of Seonjo, who was educated by Sarim, the Bannam Park clan and the Yeonan Kim clan of Sarim family lines, produced queens.

This experiment was carried out to investigate the change of kernel weight and the position of spikelet with the highest kernel weight on the spike of wheat varieties at 25, 35 and 45 days after heading from Oct. 1985 to June 1986 in Suwon Korea. Among 14 varieties tested, Suwon 239, with the latest maturing time, has been highest kernel weight of 14.9g, followed by Olmil, Geurumil and Eunpamil at 25 days after heading. Increment of grain weight was the most between 26 and 35 days after heading. Geurumil and Milyang 26 have the hightest kernel weight increment of 25g and Milyang 25 has the lowest of 13g during this period. Between 36 and 45 days after heading, however, Milyang 25 has much grain weight increment of 15g, followed by Suwon 242, Suwon 241 and Tapdongmil while Eunpamil and Olmil have very little increment in this period. There are three patterns of grain filling process. First, Suwon 242 and Milyang 25 show slow and progressive grain filling pattern from early to late period. Second, Eunpamil, Olmil and Suwon 239 which have lightier kernel weight of 34 to 37g show rapid grain filling patteren, nearly completing accumulation process by 35 days after heading. Third, the other varieties show that most of accumulating process was made between 26 and 35 days after heading but some process was continued untill even later period. Highly positive quadratic regression coefficient was between the position of spikelet on the spike and kernel weight, thus upper and lower part of spike having lighter kernel and middle part of spike, heavier kernel which were in the 8th to 10th spikelet on the spike.
