Purpose: To determine whether there are significant differences between the retinal thicknesses of the macular area in eyes of healthy Koreans compared with normative data using OCT3 (version 4.0). Methods: The study was performed in 111 eyes of 71 adults between the ages of 20 and 69 with corrected vision of 0.8 or greater and no systemic or ocular disease. The subject group was designed to have a similar age distribution to that of normative data. An OCT3 fast macular map was used to measure macular thickness. The results were further analyzed and compared with the normative data. Results: The overall results from the subject group were similar to the normative data. However, the nasal parts of the outer ring were thicker than the normative data and the temporal parts of the outer ring were thinner (p<.0001). When each age group was compared, the thickness of the superior part of the inner ring and the nasal part of the inner and outer rings were thicker than the normative data in the age groups of twenties and thirties (p<.05). For the nasal parts of outer ring, the macula were thicker by OCT examination than the normative data in 25.2% of subjects, although they were clinically normal. Conclusions: Macular thickness in healthy Koreans was generally similar to the normative data of OCT3. However, a slight difference may exist and must be considered when measuring and interpreting macular thickness measurements.

Purpose: To determine the preoperative factors of different types of diabetic macular edema (DME) classified using Optical Coherence Tomography (OCT) and to evaluate the short-term therapeutic effects and pattern changes of intravitreal triamcinolone acetonide injection (IVTA). Methods: Seventy-seven eyes of 60 patients, who had been previously diagnosed with DME through fundoscopy and fluorescein angiography, were enrolled, and each patient was classified as one of three DME types according to his/her OCT features: Type 1, diffuse retinal thickening; Type 2, cystoid macular edema; and Type 3, serous macular detachment. We compared age, sex, the duration of diabetes mellitus (DM), and decreased visual acuity (VA). We analyzed VA, intraocular pressure (IOP), foveal thickness (FT), total macular volume (TMV), and pattern changes that occurred between pre-operation and 1 month post-operation. Results: The duration of DM was short in Type 3 DME patients. There were no differences in age or the duration of decreased VA. Pre-operative VA was higher in Type 1 than in Type 2 or 3 patients. FT and TMV increased in thickness from Type 1 through Type 3. VA after IVTA improved in Types 2 and 3. FT and TMV after IVTA decreased in each type. However, the extent of the changes in Types 2 and 3 was greater than that in Type 1. Seventy-four percent of Type 2 and 83% of Type 3 changed to Type 1 after IVTA. Conclusions: This study found that there were differences in the therapeutic effect of IVTA among patients with different DME patterns. According to our results, the effectiveness of IVTA can be predicted, which we believe will help to objectively determine DME treatment. J Korean Ophthalmol Soc 2008;49(10):1611-1618

Purpose: We describe a very rare the leiomyosarcoma that developed in the conjunctiva. Methods: A 59-year-old man was treated at another hospital two months before presenting to our institution. He had not gotten any better and so was admitted to our hospital. He had normal visual acuity and intraocular pressure. However, we found a geographic, highly vascularized mass involving the corneal limbus in the medial bulbar conjunctiva, from which a pterygium had been removed a year previously. An excision of the mass was carried out to detect a suspected conjunctival intraepithelial neoplasm. Results: Tissue obtained from operation had cells with thin nuclei, spindle cells with pleomorphic cigar-shaped nuclei and eosinophilic cytoplasm, atypical cells, and from four to five mitotic figures under ten high power field. In immunohistochemical staining, Vimentin, Smooth muscle actin (SMA), Desmin, CD68 stained positively and cytokeratin, Cam5.2, S-100, HMB-45, CD 34 stained negatively. We found no clues of other origins from the general physical examination. Considering these factors, we conclude that this was a Stage I, G2T1aN0M0 leiomyosarcoma with moderate differentiation. Conclusions: Analysis by immunohistochemical staining is necessary to detect leiomyosarcoma in the conjunctiva, as it is very rare and hard to diagnose by the histologic method alone. We report a leiomyosarcoma of the conjunctiva after pterygium excision, and suggest that it be considered a differential diagnosis of conjunctival masses, even though it is very rare.

Purpose: To evaluate the postoperative changes of stereopsis after surgical correction of adult strabismus. Methods: We retrospectively evaluated strabismus patients older than 16 years at the time of operation at our hospital between April of 1999 and December of 2006. We retrospectively examined the medical records of 53 exotropia and 11 esotropia patients. We divided the pre-operative stereopsis into three groups:above 3000 arc of sec, between 3,000 to 100 arc of sec, and below 100 arc of sec. We analyzed the correlation between the post-operative status of stereopsis and the pre-op type of strabismus, the onset and duration of strabismus, and the presence or absence of amblyopia. Results: In patients who had pre-op stereopsis above 3,000 arc of sec, 31.6% showed improvement, whereas 77.8% of patients who had pre-operative stereopsis between 3,000~100 showed improvement; this value was 89.5% for patients with pre-operative stereopsis below 3000. 94.5% of patients in the intermittent exotropia group who had a good pre-operative stereopsis condition showed postoperative improvement and maintenance. For those patients with poor stereopsis at pre-operative, 32.2% of patients with exotropia and 18.1% of patients with esotropia showed improvement. Stereopsis decreased when consecutive esotropia occurred. Conclusions: This study showed deterioration of stereopsis in patients with consecutive esotropia. Post-operative stereopsis was correlated with the pre-operative stereopsis status and with the type of strabismus. No other factors that we examined were correlated with stereopsis. Post-operative stereopsis in exotropiaand intermittent exotropia were better than esotropia and constant exotropia. J Korean Ophthalmol Soc 2008;49(11):1807-1811

The aim of this study was to measure the suprathreshold taste intensity for NaCl, sucrose, citric acid, and quinine HCl in elderly Korean women using a whole-mouth, sip-and-spit procedure, employing the method of magnitude matching. The results were analysed in terms of aging, menopause, and salivary flow rate. 31 elderly women (mean age; $50.8{\pm}5.1$ years) and 30 young women (mean age; $25.1{\pm}1.71$ years) were included for the study. Subjects were instructed to give nonmodulus magnitude estimates to the intensities of five concentrations each of sucrose, NaCl, citric acid, and quinine HCl; distilled water; 6 loudness level of a 1,000-Hz tone, using the same 9-point intensity scale. Each of the 21 taste stimuli and 6 auditory stimuli are presented in random order twice. The auditory function is used to assess the absolute intensity function of the subject's taste system. The results were as follows; 1. Comparing to young women, elderly women showed decreased taste intensities for lower concentration solutions of NaCl and sucrose. However, other solutions didn't show any difference in taste intensities between young and elderly women. 2. There were not significant difference in perceived taste intensities for NaCl, sucrose, citric acid, and quinine HCl between menopause and pre-menopause women in elderly women group. 3. There were not significant difference in perceived taste intensities for NaCl, sucrose, and quinine HCl between low salivation women and high salivation women in elderly women group. 4. The low salivation women in elderly group showed higher taste intensity for low concentration citric acid than high salivation women.

한국의 비판사회학 1998~2008

윤상철(Yoon Sang-Chul) 비판사회학회 2010 경제와 사회 Vol.- No.85

비판사회학은 한국산업사회학회(비판사회학회) 중심의 사회학자들이 한국사회에 대한 진보적이고 개혁적인 의제를 설정하고 사회하층의 정치적, 사회경제적 이해를 학문적, 실천적으로 중시하는 사회학적 경향이다. 그러나 1998~2008년간의 경향을 살펴보면, 사회학의 분과학문적 위상이 강화되고, 학술운동적 성격이나 사회운동과의 연계가 약화되며, 인적 확대재생산의 한계에 봉착하였고, 순응적 학문활동이 강화되고 있다. 다른 해석으로는 학문적 토양이 다양화되고 풍요로워졌으며, 마르크스주의적 영향력에서 벗어나면서 외부와의 대화가 확장되었고, 기술적 전문화가 진전되고, 분석적 방법론적 엄밀성이 제고되었다는 점 등을 들 수 있다. 이러한 경향을 한국산업사회학회, 비판사회학대회, 계절별 워크숍, 《경제와사회》를 중심으로 살펴보면, 거시담론의 소멸과 경제위기, 수평적 정권교체와 남북화해, 신자유주의와 미국 헤게모니, 시민사회운동의 개화 등의 계기를 겪으면서, 산업/노동, 정치/민주화, 경제/조직, 사회운동, 여성, 이론, 계급/계층 등의 연구영역을 중심으로 급속한 제도화와 방향성 상실, 분과학문적 성격 강화, 구체적인 대안제시의 좌절 등을 보여주고 있다. 그 대안으로서 학문적 기준과 실천적 기준을 조응시키고, 후속세대 연구자들의 인적 재생산을 중시하며, 학문과 사회적 실천활동의 연계를 중시하고, 대중을 향한 사회학을 시도해야 한다는 점을 제시한다. The Critical Sociology is the academic tendency in the discipline of sociology to establish progressive and reformative agenda on Korean Society and make much account of politicaland socio-economic interests of lower social stratums, led by liberal sociologists of Korean Industrial Sociological Association. The tendency of Korean critical sociology in the last decade 1998-2008 showed that interdisciplinary research activities got weaker, close connections with social movements debilitated, young researchers did not prefer this tendency, and adaptive academic activities prevailed. Positively thinking, academic atmosphere became diverse and affluent, communication with other theoretical perspectives expanded out of Marxist paradigm, technical specialization and analyticalmethodological rigidity were improved. In this process, the critical momentums are the collapse of socialist regime, the economic crisis of foreign exchange, horizontal power exchange, the rapid thaw in South-North Relation, Neo-liberalism in the US hegemony, and vitalization of civil social movements. The remaining and realizable alternatives are to find the correspondence of Academic and practical criteria, settle the lack of young human resources, present the role of academic activities in social practice, and contribute to need and expectation of the masses.

기독교 관점에서 결핍의 문제를 어떻게 볼 것인가?

윤상철(Sang-Chul Yoon) 한국기독교경제학회 2018 OIKONOMOS Vol.5 No.2

기독교적인 관점에서 결핍은 불순종으로 에덴동산에서 쫓겨난 이후 인류가 직면하게 된 숙명이다. 전능하신 하나님으로부터 유리된 인간은 결핍의 문제를 해결하고 그들의 능력을 극대화하기 위해서 계급제(Hierarchy)와 시장(Market)을 조직화하게 되지만, 오히려 소수의 지배로 인간이 소외되게 되고 돈으로 상징되는 물질의 권세에 사로잡히게 된다. 그 결과로 인류에게는 비가시적인 전능하신 하나님과 가시적인 권세로서의 돈이 신격화되어 두 주인으로 작용하게 된다. 인간이 직면하고 있는 결핍의 문제는 단지 물질의 부족만이 아니라 하나님의 부재에서 비롯된다 할 수 있다. 기독교 관점에서 볼 때, 결핍의 근본적인 해결은 오직 예수 그리스도의 구원에 의한 하나님 나라의 사랑의 공동체(Community)를 회복함으로서 만 가능한 일인 것이다. In the point of Christian view, the man that was banished from the Garden of Eden through the disobedience of Adam should be in want. The man that was separated from almighty God invented the institutions such as Hierarchy and Market in the world in order to solve the problem of ‘Want’ and to maximize his power. However, mankind was neglected by the rule of the minority and captivated by the power of wealth such as money. As a result, mankind had been faced with two masters who are the intangible almighty God and the tangible power of money as God. The problem of ‘Want’ that is now being faced by mankind can be originated not only from the scarcity of wealth but also from the absence of God. The biblical vision shows that the restoration of community of love in the kingdom of heaven can come to solve the problem of ‘Want’ ultimately, only through the redemption of Christ Jesus.

세대정치와 정치균열

윤상철(Yoon Sang-chul) 비판사회학회 2009 경제와 사회 Vol.- No.81

이 연구는 1997년 이후 세대정지가 출현, 소멸하는 동학을 정치균열과의 관계 속에서 분석하고 있다. 세대의 형성은 정치사회적 환경 속에서 이루어지지만, 정치세대의 형성은 그러한 세대를 정치적으로 동원하는 정당과 그러한 세대균열을 정치균열에 전화시키는 정치체제가 존재함으로써 가능해진다. 이러한 관점을 쥐함으로써 한국정치에서 세대정치가 2000년부터 급격하게 제도적 선거정치 안에서 출현하였다가 급격하게 소멸하게 되었고 이후의 세대정치가 사회운동의 정치로 나타나게 되는 이유를 해명할 수 있다. 향후 세대정치 양상은 쟁점을 제기하는 정치세대는 있지만 정치변동을 주도하는 정치세대는 부재한 상황으로 전개될 것이다. This study analyzes dynamic of appearance and fadeout of Generation Politics since 1997, in relation to political cleavage. While generation in general can be formed in the specific socio-political environment in the civil society, formation of political generation needs political parties, which mobilize those generations, and political regime, which transforms the generational cleavage into political cleavage in the area of political society. From this perspective, we can explain why generation politics appeared and faded out abruptly in institutional electoral politics since 2000, and moreover transformed into social movement politics. Hereafter we expect that there will be a political generation, initiating some political issues but any political generation cannot lead political change.

Trade in information technology and wage inequality in the digital economy : The case of Korea

Sang-Chul Yoon(윤상철) 한국무역학회 2008 무역학자 전국대회 발표논문집 Vol.2008 No.8

This paper examines the impact of trade in information technology (IT) on wage inequality in the digital economy. The empirical results based on the quarterly data for the period 1994-2004 in Korea show the evidence supportive of the view that trade in IT as intermediate inputs has increased the situation of wage inequality in the digital economy, which supports the Feenstra-Hanson (2001) hypothesis.

무상원조가 경제성장에 미치는 효과: 한국의 중점협력 수원국들에서의 증거

윤상철 ( Sang-chul Yoon ) 한국경제통상학회(구 한국경상학회,한국국민경제학회) 2016 경제연구 Vol.34 No.3

본 논문은 우리나라의 42개 중점협력 수원국들을 대상으로 1996-2013년 기간의 자료를 사용하여 이 국가들에 제공되는 무상원조가 수원국의 경제성장에 의미있는 기여를 하는지를 실증 분석한다. 동 연구의 패널분석 확장모형의 추정결과에 의하면 정태적 및 동태적 분석 모두에서 무상원조가 경제성장에 통계적으로 유의미한 양(+)의 영향을 미치는 것으로 나타난다. 그리고 이러한 무상원조의 경제성장 효과는 물가상승률로 측정된 거시경제정책 조건에 의해 유의미한 영향을 받고 있지 않는 것으로 분석되며, 이와 함께 경제성장의 무상원조에 대한 수확체감의 증거가 다소 나타나고 있는 것으로 보인다. Using the panel analysis for 42 main development partners of Korea during 1996-2013, this paper analyzes empirically the impact of grants on economic growth in the recipient countries. The estimation results of both static and dynamic analysis in the extended panel model show that grants have a positive and significant effect on economic growth. In particular, the positive effect of grants on economic growth is revealed not to be conditional upon macroeconomic policy expressed in terms of inflation rate. However, there are some evidence of diminishing return to grants.
