Purpose: To report the clinical finding of 3 patients with focal choroidal excavation in the macula detected by spectral-domain optical coherence tomography (SD-OCT). Case summary: Five eyes of 3 patients with focal choroidal excavation detected by SD-OCT were enrolled in the present study. All patients had myopia (average refractive power -5.60 diopter). Two of the 3 patients had focal choroidal excavation in both eyes. All 5 eyes revealed foveal pigmentary changes on fundus examination. The excavation area in the autofluorescence image was hypofluorescent. Fluorescein angiographic finding was normal to various degrees of hyperfluoresence. Indocyanine green angiography revealed hypofluoresence at the excavation area. The excavation involoved from the retinal pigment epithelium layer to the external limiting membrane or outer nuclear layer and average choroidal thickness at excavation were statistically thinner than the uninvolved area based on SD-OCT (p = 0.002). Retinoschisis, serous pigment epithelial detachment and choroidal neovascularziation (CNV) were detected individually in 3 eyes. The other 2 eyes had no specific abnormalities. Conclusions: During the follow-up period, the choroidal excavation remained relatively stable in 4 of 5 eyes, but CNV developed in 1 eye. Therefore, intravitreal bevacizumab injection was performed. Longer follow-up periods are necessary to determine the etiology, clinical course and visual prognosis of eyes with focal choroidal excavation. J Korean Ophthalmol Soc 2014;55(6):941-946

We report on the capacitively coupled O2 plasma etching of PMMA and polycarbonate (PC) with a diffusion pump. Plasma process variables were process pressure and CCP power at 5 sccm $O_2$ gas flow rate. Characterization was done in order to analyze etch rate, etch selectivity, surface roughness, and morphology using stylus surface profilometry and scanning electron microscopy. Self bias decreased with increase of process pressure in the range of 25$\sim$180 mTorr. We found an important result for optimum pressure for the highest etch rate of PMMA and PC, which was 60 mTorr. PMMA and PC had etch rates of 0.46 and 0.28 ${\mu}m$/min under pressure conditions, respectively. More specifically, etch rates of the materials increased when the pressure changed from 25 mTorr to 60 mTorr. However, they reduced when the pressure increased further after 60 mTorr. RMS roughnesses of the etched surfaces were in the range of 2.2$\sim$2.9 nm. Etch selectivity of PMMA to a photoresist was $\sim$1.5:1 and that of PC was $\sim$0.9:1. Etch rate constant was about 0.04 ${\mu}m$/minW and 0.02 ${\mu}m$/minW for PMMA and PC, respectively, with the CCP power change at 5 sccm $O_2$ and 40 mTorr process pressure. PC had more erosion on the etched sidewall than PMMA did. The OES data showed that the intensity of the oxygen atomic peak (777.196 nm) proportionally increased with the CCP power.

본 연구는 보통의 사람들이 금융취약계층에 이른 후 그 상황에서 벗어나 게 되는 과정을 심층적으로 탐색함으로써 금융취약계층의 재기 과정을 밝히 는 데에 목적이 있다. 자료수집을 위해 공·사적 채무조정을 신청한 9명을 대 상으로 심층면접을 실시하였으며, Strauss와 Corbin의 근거이론분석방법에 따 라 분석한 결과를 근거이론 모형으로 제시하였다. 개방코딩에서 149개 개념, 26개 하위범주, 11개 상위범주를 도출하였으며 이를 토대로 축코딩을 실시 한 결과 중심현상은 ‘빚에 이끌린 삶’으로 나타났다. 맥락적 조건은 ‘불안정 한 일자리와 질병’, ‘낮은 소득과 생활고’였으며, 작용·상호작용전략은 ‘공적 지원의 활용’과 ‘스스로 재기하려 애씀’이었다. 중재적 조건은 ‘책임감과 신 세 갚으려는 마음’, ‘도움 받을 용기’, ‘건강상태와 나이’로 나타났다. 금융취 약계층의 재기 과정을 설명하는 핵심범주는 ‘빚에 이끌린 삶에서 헤어나기’ 였다. 금융취약계층의 재기 과정은 추락·고립 단계, 발버둥 단계, 불안한 생 존 단계로 분석되었다. 분석결과를 토대로 금융취약계층의 재기와 일상의 회복 지원을 위한 사회복지적 대응방안을 제시하였다. This study examined the recovery process of the financially vulnerable populations through in-depth research into them. The data were collected through in-depth interviews with 9 applicants for public or private debt adjustment, and were analysed with the grounded theory method of Strauss and Corbin. In open coding, 149 concepts, 26 subcategories, and 11 categories were developed and in axial coding, the central phenomenon was ‘life drawn by debt’. Contextual conditions were ‘unstable jobs and diseases’ and ‘low income and hardships of life’, while actions and interactions strategies were ‘utilizing public support’ and ‘attempting to recovery on their own.’ Intervening conditions were ‘responsibility and willingness to repay kindness’, ‘courage to get help’, and ‘health status and age.’ The core category explaining the recovery process of the financially vulnerable populations were ‘getting out of debt-driven life.’ The recovery process of the financially vulnerable populations were identified as a stage of falling and isolation, a stage of struggling, and a stage of unstable survival. Based on these findings, this paper suggests social welfare countermeasures for the financially vulnerable populations.

박주홍(Park, Joo-Hong) 계명대학교 산학연구소 2010 經營經濟 Vol.43 No.2

This paper examines the determinants of international transfer pricing. Especially, based on the former researches it classifies them into two factors to influence international transfer pricing, i.e. firm’s internal and external factors. Firm’s international factors are as follows: company-wide maximization of profit, strengthening of subsidiary’s competitiveness, financial status of headquarters and subsidiary, performance evaluation of subsidiary, stable supplies and obtaining of materials, and transfer size between headquarters and subsidiary. The followings are firm’s external factors: different taxation between home and host countries, currency fluctuations, inflation rate in the host country, import quotas, foreign currency controls, and joint venture regulations in the host country. This study also provides managerial implications for determinant evaluation of international transfer pricing.

This paper examines the German corporate governance and the recent changes in the German "Corporate Governance Kodex". The German corporate governance is characterized by the two-tire board system, the co-dettermination, the active role of bank and determination by proxy. The two-tier board consists of the management board and the supervisory board. For example, in Germany the supervisory board of lage corporations is composed of 20 members, 10 of which are elected by the shareholders, the other 10 being employee representatives. Through the co-determination workers form special bodies-they also elect or select worker representatives in supervisory organs of companies. And the bank takes a central role in the German corporate governance and makes a determination by proxy in minority shareholder"s name. The German "Corporate Governance Kodex" is quite unique beceause it applies a Code of Good Practice to a two-tier board system. Especially, it defines the role, functions and relationships between the management and supervisory board. This article deals with recent changes in the German system of corporate governance.

한국, 독일과 미국의 경영전문대학원 선택과목 커리큘럼에 대한 비교연구

박주홍 ( Joo Hong Park ) 한독경상학회 2015 經商論叢 Vol.33 No.2

본 연구는 한국, 독일과 미국의 경영전문대학원 선택과목 커리큘럼을 비교분석하였다. 이러한 비교분석을 수행하기 위하여 이들 국가의 선도적 경영전문대학원 각각 5개씩을 선정하고, 이와 관련된 자료를 수집하기 위하여 웹 사이트 조사를 수행하였다. 주요 비교결과는 다음과 같다. 한국의 경영전문대학원 선택과목은 총 156개 과목으로 독일보다는 과목의 수가 많고, 미국보다는 과목의 수가 약간 적은 것으로 밝혀졌다. 이러한 결과는 한국의 경영전문대학원 학생들에게 다양한 선택과목을 수강할 수 있는 기회가 많이 제공되고 있다는 것을 의미한다. 전체적으로 볼 때, 한국의 경영전문대학원 선택과목의 수는 분석적 과목, 기능적 과목, 글로벌 과목, 소프트스킬 과목 및 사회적 책임 과목의 순으로 나타났다. 독일의 경영전문대학원 선택과목은 총 53개 과목으로 미국과 한국에 비해 과목의 수가 매우 적은 것으로 나타났다. 이러한 결과는 독일의 경영전문대학원 학생들이 다양한 선택과목을 수강할 수 있는 기회가 매우 적다는 사실을 보여준다. 독일의 경영전문대학원 선택과목의 수는 분석적 과목, 기능적 과목, 글로벌 과목, 사회적 책임 과목 및 소프트 스킬 과목 순으로 확인되었다. 마지막으로, 미국의 경영전문대학원 선택과목은 총 174개 과목으로 한국보다 다소 많으며, 독일보다 과목의 수가 매우 많은 것으로 나타났다. 미국의 경영전문대학원 선택과목의 수는 기능적 과목, 소프트 스킬 과목, 분석적 과목, 사회적 책임 과목 및 글로벌 과목의 순으로 나타났다. 그러나 개설한 선택과목의 수는 한국과 독일에 비해 상대적으로 많은 것으로 확인되었기 때문에 미국의 경영전문대학원 학생들은 다양한 선택과목의 수강기회를 갖는 것으로 볼 수 있다. 본 논문은 선택과목에만 국한하여 연구를 하였기 때문에 MBA 과정의 다양한 교육상황에 대한 내용을 광범위하게 다루지 못한 한계를 지니고 있다. This comparative study analyzed the MBA elective curriculum between the Korean, and the German and the American Graduate Schools of Business (GSB). To perform comparative analysis, the 5 leading Korean GSBs, the 5 leading German GSBs and 5 leading American GSBs were selected. The research was performed by web-based survey. Major results are as follows: The number of electives at Korean GSBs is 156 subjects. It is more than that of German and fewer than that of American GSBs. Especially, the number of analytical, functional and global electives at Korean GSBs is relatively high. The number of electives at German GSBs is 53 subjects. It is fewer than that of Korean and American GSBs. It means that the German MBA students can not have a better chance to take an elective courses compared with Korean and American students. Finally, the number of electives at American GSBs is 174 subjects. It is more than that of Korean and German GSBs. The American GSBs provided not only various functional subjects, but also plentiful soft-skill related and analytical subjects. Because of limited research subject which focused only on the elective curriculum, it couldn’t analyze the different situation of GSBs in Korea, Germany, and USA. A follow-up study should be performed to develop electives after consideration of environmental changes and industrial needs.

This study compares international management curriculum between Korean and German universities. First of all on the basis of literature, it discusses theoretical background on the location of international management in the business administration. Based on the data collection through the internet Web sites, it analyses international management curriculum between Korean and German universities. Especially, it analyses international management curriculum in terms of general theory, specific theory, functional theory, seminars and internship programs, which related to international business. The findings of this study are as follows: 1) There is little difference between international management curriculum in terms of general and functional theory. 2) According to results, which related to specific theory, there is difference between two countries. German universities offer more specific subjects than Korean universities. 3) In spite of difference of school system between two countries, it seems that German universities provide better seminars and internship programs than Korean universities. This study can have a limitation with respect to comparability, which resulted from difference of school system between two countries, None the less. the results of this study can provide helpful implications to modify and develop international management curriculum for Korean universities.
