신용호,박영환,김용민,Shin, Y.H.,Park, Y.H.,Kim, Yong-Min 한국진공학회 2007 Applied Science and Convergence Technology Vol.16 No.4

실리콘 기판위에 성장된 ZnO 나노막대에 NiO를 코팅하여 core-shell 형태의 나노막대를 제작하였다. 이렇게 제작된 나노막대를 수소 분위기에서 열처리한 결과 ZnO 나노막대 표면에 Ni 나노점들이 형성됨을 확인하였다. 이러한 여러 종류의 나노막대의 저온(5K)에서 광발광 (photoluminescence) 특성을 연구하였는데 $ZnO{\rightarrow}NiO-ZnO{\rightarrow}Ni$ 나노점-ZnO 순서로 시료가 변화함에 따라 속박된 exciton들의 전이 에너지와 진폭이 변화함을 확인하였다. ZnO에 비하여 NiO-ZnO 시료의 경우 받개에 속박된 exciton ($A^0X$) 전이가 크게 감소함을 보이나 Ni 나노점-ZnO 시료의 경우 $A^0X$ 전이가 가장 우세함을 보인다. 이러한 현상은 수소화 과정에서 침투한 Ni과 수소 이온이 주개로 작용하였기 때문이다. We fabricated NiO coated ZnO nanorods using ZnO nanorods grown on a Si substrate. After thermal hydrogenation process of these NiO-ZnO core-shell nanorods, we confirm that Ni nanodots were built up on the surface of ZnO nanorods. Photoluminescence (PL) measurements at T=5 K were made to understand the optical properties of these various nanorods. As samples sequencially transformed into $ZnO{\rightarrow}NiO-ZnO{\rightarrow}Ni$ nanodot-ZnO, PL transition energies and intensities are varied as well. In comparison to pure ZnO nanorod, the acceptor bound exciton ($A^0X$) became the minor peak for NiO-ZnO nanorods. On the other hand, for Ni nanodot-ZnO sample, ($A^0X$) transition peak intensity became the most dominant peak. This is due to the fact that during thermal hydrogenation process, appreciable amounts of Ni and hydrogen ions defused into ZnO nanorod which played as accepters.

원자층 증착법으로 성장한 ZnO-ZnMgO 양자우물의 광전이 특성

신용호,김용민,Shin, Y.H.,Kim, Yongmin 한국진공학회 2013 Applied Science and Convergence Technology Vol.22 No.1

원자층 증착법을 이용하여 서로 다른 양자우물 폭을 갖는 ZnO-ZnMgO 양자우물들을 제작하였다. 제작된 시료들은 양자우물 폭에 따라 서로 다른 광전이 특성을 나타내는데 우물 폭이 1.5 nm인 시료의 경우 후 열처리에 따른 Mg의 확산에 따라 양자화된 에너지 준위가 형성되지 않았고 이보다 더 넓은 폭을 갖는 시료들의 경우 양자화된 준위의 광전이를 보임을 확인하였다. We fabricated ZnO-ZnMgO single quantum well (SQW) samples having different well-widths by using the atomic layer deposition technique. The QW samples exhibit different optical transition behaviors with different QW widths. We confirm that when the well-width of 1.5 nm does not have a confined quantum energy level due to the Mg diffusion into the well caused by after-thermal treatment whereas the QWs wider than 1.5 nm show optical transitions between the confined energy levels.

재무곤경이 비정상생산원가에 미치는 영향

신용호(Shin, Yong Ho),문상혁(Moon, Sang Hyuk) 한국국제회계학회 2013 국제회계연구 Vol.0 No.49

본 연구는 재무적 곤경 및 파산위험 등으로 계속기업에 대한 의문 의견이 비정상생산원가에 어떠한 영향을 미치는지를 조사하였다. 재무적 곤경 및 파산위험에 직면해 있는 기업의 경우 악화된 영업활동순현금흐름을 개선하기 위하여 다양한 현금유입의 원천을 찾고자 노력할 것으로 예상된다 또한 계속기업으로서의 존속 가능성이 불확실한 기업일수록 이익의 상향조정을 통한 성과를 개선하고자 할 유인이 존재한다. 재고자산은 주요 영업활동의 대상인 자산이며, 경영자는 재고자산의 구입 및 생산여부, 적정재고의 보유 및 판매에 대한 재량권이 있다. 따라서 경영자는 제품의 과대생산을 통한 고정제조간접 원가의 자본화로 발생하는 이익의 상향조정 또는 보유 재고자산의 처분을 통한 현금유입을 확보 중 하나를 선택할 것이다. 2001년부터 2009년 사이에 유가증권시장과 코스닥시장에 상장된 제조업 중 9,887기업-연도 대상으로 실증분석 한 결과 계속기업으로서의 존속가능성이 불확실한 기업일수록 그렇지 않은 기업에 비해 비정상생산원가가 작은 것으로 나타났다. 이러한 결과로 재무곤경이나 파산위험 등으로 계속기업 의견을 받은 기업은 보유 재고자산의 처분을 통한 현금유입을 확보하고자 노력하고 있음을 예측할 수 있다. 재무적 곤경을 겪고 있는 회사의 재고자산과 관련된 전략적 선택에 대하여 실증분석 한 본 연구의 결과는 학계와 실무계에 유용하게 사용될 것으로 판단된다. It is very important to understand whether firms face the risk of financial stress and bankruptcy effort to improve bad operating cash flow or increase manage earnings. So we examines the effect of financial stress on abnormal production costs. In this study, we use going concern opinion as proxy of financial stress. The sample consists of non-banking firms(9,887 firm-years) with December fiscal year listed in Korean Stock Exchange(KRX KOSPI Market and KRX KOSDAQ Market) over 2001-2009. Empirical findings are summarized as follows; As it is shown in table 4, firms receiving going concern opinions have a significant negative relation abnormal production costs. These results imply that firms face the risk of financial stress and bankruptcy do not tend to lower the cost of sales by increasing production volumes, but tend to secure cash through the sale of holding inventories. In the raising interest for strategic choice of firms receiving going concern opinion, the results of this study can provide beneficial information to the academic, business circles and stakeholders by verifying effect of financial stress on abnormal production costs.

고정비용과 용량제약이 있는 다품종 흐름 네트워크 설계를 위한 모의풀림 알고리즘

In this paper, we propose a simulated annealing algorithm for the fixed-charge multicommodity capacitated network design problem using commodity sequence neighborhoods. For a commodity sequence, a corresponding flow path network is obtained by a network construction method and it is improved by an arc-blocking method. The flow path network is further improved by solving a linear programming model after fixing binary variables according to the result of the arc-blocking method. To evaluate the performance of the suggested algorithm, computational experiments are performed on well-known benchmark problems. Results of computational experiments show that the suggested algorithm gives better solutions than a commercial optimization software package and an existing algorithm.

Exchange is absolutely necessary for a divided country to achieve peaceful reunification. To examine the exchange of the East-West Germany Trade, which is a successful model for the exchange, is accordingly valuable. Black marketeering between military occupied areas is the starting point of the East-West Germany trade. Understandably, economic exchange is needed since the one nation, one economic unit is suddenly separated by artificial means. Since the two German governments has become established, they leaded the trade and the amount of trade increased so that by 1989, the last year of the trade, it was 15,309 million VE(DM), which was the 20 times growth of that of the 1950s. This volume could be in Korean currency approximately more than 5 trillion won. East-West Germany Trade was many small businesses from broad range of fields joined, mostly with daily products. Therefore it was politically less affected and was a great help to protect and sustain the national unity. A consistent and determined stance of the German Federal Republic(West Germany) on the East-West Germany trade is that East Germany and West Germany is in legally still existing the whole country(German Empire), so that they are not in a mutually foreign relationship, rather in a special relationship, and all the state institutions have the legal obligations to protect and sustain the nationality and national unity of this whole country and struggle to integrate the government power that is separately exercised in real. Therefore the German Federal Republic struggled to carry out this regardless of economic interests. According to this position, West Germany strived to extend trade between East and West Germany and did not impose tariffs. Furthermore, they explained their position actively to friendly nations (especially EC and GATT member countries) and achieved their understanding. In consequence of the effort of West Germany`s government, 1989/90, when the East-European bloc collapsed, surrounding nations could easily understand the unifications policy of Germany. By the trade between East and West Germany, the Military Government Law (Militärregierungsgesetz) number 53, proclaimed during the Military Occupations Era, has been applied until the reunification of Germany. Although the Western Allies gave German Republic the right of change, German Federal Parliament kept the name and regulations of the Military Government Law number 53. Even when the Law of Foreign Economic was enacted by the German Federal Parliament, it was not applied to the trade between East and West Germany. It is seen as an action to maintain the uniqueness of the trade between East and West Germany. In regards to the unconstitutionality controversy of the Military Government Law number 53, the German Federal Constitutional Court judged that it is hard to apply the Fundamental Law principles to the `general permission and exceptional prohibition` and discretion problem of intendance of permission of rights to freedom. Moreover, Constitutional Court also decided that with the trade between East and West Germany, national agencies should keep the direction of liberalization and an arbitrary regression is not acceptable here. This also has many implications for Korea. Berlin Convention is the international legal convention that becomes the basis of the trade between East and West Germany. This convention includes a broad range of the annex, memoranda, etc through 130 days of conference. It is not always a good treaty when the period of negotiation is long and contents are lot, however, there is no doubt that this convention is formed extremely carefully. Besides, after the convention became effective, both governments have been strived to perform, complement and develop the convention by crossing east and west Berlin every 2 weeks. It is easy to figure out their efforts on the trade between two states. One characteristic of Berlin Convention is the way of payment s
