이 글은 지방정부의 민원행정서비스 만족도를 평가하고, 개선방안을 제시하는데 목적을 두었다. 연구는 경북 영천시를 대상으로 설문조사를 실시하여 분석하였다. 분석결과, 첫째, 민원행정서비스는 친절하고 신속하게 이루어졌지만, 과거 획일적이고 공급자 위주의 행정을 탈피하여 수요자 중심의 행정을 전개하기 위해 서비스 차별화 전략이 필요하다. 둘째, 민원행정서비스에 대한 만족도는 전체적으로 매우 높은 것으로 나타났다. 특히 민원사항에 대한 충분한 설명과 지식, 정보제공, 민원인을 대상으로 한 간단한 문서교육 등이 필요하다. 셋째, 민원시책에 대해서는 만족도가 낮았다. 이를 제고하기 위해서는 전체주민을 고려한 행사, 다양한 방법 (각종매체, 모임)을 통한 홍보활동전개, 특정한 날을 정하기보다는 상시적인 행사, 시의 편리한 시간에 행사 일을 맞추기보다는 주민의 시간을 고려한 행정 등이 필요하다. 마지막으로 민원행정서비스에 대한 개선책으로 각종 법규정비의 간소화가 중요하다. 또 복합민원만을 one-Stop, non-stop으로 처리할 수 있는 별도의 민원 부서가 필요하다. This paper propose to evaluate satistaction and policy orientation of civi1 service in Local government. Its analyze through questionnaire method in case of Yeong-cheon city, Gyeongbuk. The results of this study are as follows: First, civil service enforce friendly and speed, but its need defficiental strategy of civil service to deployment custommer-oriented administration deviate from fixed supply-oriented administration of the past. Second, the satisfaction of civil service totally high. Especially, its need explanation and knowledge sufficiently for civil service, furnishment of information, document education for citizen etc. Third, the satisfaction of civil program somewhat low. In order to the rise service program satisfaction, local government should open citizens’ events, public relation through mass media, civil conference, simplicity of law etc.

반도체 레이저의 이득곡선에서의 비포물선형 효과

김동철,유건호 慶熙大學校 레이저 工學硏究所 1997 레이저공학 Vol.8 No.-

Use of one-band model in the calculation of gain of semiconductor lasers is convenient because it is easy to understand and takes less time to implement. However, it gives an error in the gain by neglecting the nonparabolicity. In this paper, we study the limit of the one-band model by comparing the gain calculated by the one-band model with that by a multiband model. We find that, if the active layer is bulk, the peak gain by the one-band model is approximately same as that by a multiband model. However, if the active layer is a quantum well, the peak gain by the one-band model is much larger, and the one-band model may not be used for a quantitative analysis.

김용성,백승훈,유경훈,구기선,형근영,김경년,조정구 圓光大學校 醫科學硏究所 1997 圓光醫科學 Vol.13 No.1-2

Kallmann's syndrome is the most common form of isolated gonadotropin deficiency, characterized by hypogonadotropic hypogonadism due to GnRH deficiency, delayed puberty and smelling difficulty. It occurs sporadic or familial pattern, and the mode of inheritence has not been fully documented. The defect in patient of Kallmann's syndrome occurs at suprapituitary level involving mechanism that regulate GnRH synthesis or release, so this syndrome classified as a secondary hypogonadotropic hypogonadism. The gonadotropin or pulsatile GnRH administration enable successful stimulation of spermatogenesis and fertility. We have experienced 1 patient with Kallmann's syndrome and presented with the review of the literature.

Yoo, Keon Hee,Lee, Soo Hyun,Sung, Ki Woong,Koo, Hong Hoe,Chung, Nak Gyun,Cho, Bin,Kim, Hack Ki,Kang, Hyoung Jin,Shin, Hee Young,Ahn, Hyo Seop,Baek, Hee Jo,Han, Dong Kyun,Kook, Hoon,Hwang, Tai Ju,Kim, Wiley Subscription Services, Inc., A Wiley Company 2011 American journal of hematology Vol.86 No.1

<P><B>Abstract</B></P><P>We report the outcome of 236 pediatric umbilical cord blood transplantations (UCBT) performed in Korea. Given that the sources of the grafts were mostly unrelated donors (<I>n</I> = 226; 95.8%), only the results of unrelated UCBT were included for all statistics. The most frequent primary disease was acute leukemia (<I>n</I> = 167). In total, 91.7% of recipients were seropositive for cytomegalovirus (CMV). The median doses of nucleated cells and CD34+ cells were 4.84 × 10<SUP>7</SUP>/kg and 2.00 × 10<SUP>5</SUP>/kg, respectively. The median times to neutrophil (>0.5 × 10<SUP>9</SUP>/L) and platelet recovery (>20 × 10<SUP>9</SUP>/L) were 18 and 45 days, respectively. Grade 2–4 acute graft‐versus‐host‐disease (GVHD) and chronic GVHD developed in 41.1 and 36.1% of cases, respectively. Forty‐five patients developed CMV disease. The 5‐year overall and event‐free survival were 47.5 and 36.9%, respectively. Multivariate analysis revealed that adverse factors for survival of the whole cohort were total body irradiation‐based conditioning (<I>P</I> = 0.007), salvage transplant (<I>P</I> = 0.001), failure to achieve early complete chimerism (<I>P</I> < 0.0005), and CMV disease (<I>P</I> = 0.001). The outcomes of the single‐ and double‐unit UCBT (<I>n</I> = 64) were similar, while double‐unit recipients were heavier (<I>P</I> < 0.0005) and older (<I>P</I> < 0.0005). We conclude that double‐unit UCBT is a reasonable option for older or heavier children and that the thorough surveillance of CMV infection and the development of an effective CMV therapeutic strategy may be especially important for Korean children, whose CMV seroprevalence exceeds 90%.

Effect of Low Temperature Annealing on ITO-on-Si Schottky Junction

Yoo, Keon,Lee, Jong-Ho IEEE 2017 IEEE electron device letters Vol.38 No.4

<P>In this letter, we investigate electrical properties of the indium-tin oxide (ITO)-on-Si Schottky junctions and the effect of a low temperature annealing on the properties. The ITOfilms are depositedbyRFmagnetronsputtering on n-type and p-type crystalline Si wafers. By measuring current-voltage and capacitance-voltage characteristics, it is foundthat a layerof positivefixedcharge is formedat the interface between the ITO and the Si by sputtering damage and that the charge layer distorts the barrier height of the ITO-on-Si junction. The low temperature annealing makes the ITO on p-and n-Si junctions ohmic-like and rectifying, respectively, by changing the barrier height.</P>

Design of a High-efficiency Fiber-to-chip Coupler with Reflectors

Keon Yoo,Jong-Ho Lee 대한전자공학회 2016 IEIE Transactions on Smart Processing & Computing Vol.5 No.2

In this paper, an inversely tapered coupler with Bragg reflectors is reported for the first time. With appropriately positioned reflecting structures, our fiber-to-chip coupler can more efficiently transmit the light from fiber to a waveguide in a photonic integrated circuit (PIC). A numerical simulation evaluated the coupler’s efficiency with the reflector. Optimized parameters that maximize the efficiency of the coupler are also investigated. Simulation results show that the reflector with appropriate parameters enhances efficiency by up to 7 dB. Likewise, Bragg metal reflectors implemented by the conventional metallization process can also improve efficiency. It is also shown that the proposed reflector enhances the coupling efficiency in a double-tip taper coupler.

Yoo Hae Won,Jin Hyun Young,Yon Dong Keon,Effenberger Maria,신윤호,Kim So Young,Yang Jee Myung,Kim Min Seo,Koyanagi Ai,Jacob Louis,Smith Lee,Yoo In Kyung,신재일,Lee Seung Won 대한의학회 2021 Journal of Korean medical science Vol.36 No.41

Background: Evidence for the association between underlying non-alcoholic fatty liver disease (NAFLD), the risk of testing severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) positive, and the clinical consequences of coronavirus disease 2019 (COVID-19) is controversial and scarce. We aimed to investigate the association between the presence of NAFLD and the risk of SARS-CoV-2 infectivity and COVID-19-related outcomes. Methods: We used the population-based, nationwide cohort in South Korea linked with the general health examination records between January 1, 2018 and July 30, 2020. Data for 212,768 adults older than 20 years who underwent SARS-CoV-2 testing from January 1 to May 30, 2020, were obtained. The presence of NAFLDs was defined using three definitions, namely hepatic steatosis index (HSI), fatty liver index (FLI), and claims-based definition. The outcomes were SARS-CoV-2 test positive, COVID-19 severe illness, and related death. Results: Among 74,244 adults who completed the general health examination, there were 2,251 (3.0%) who were SARS-CoV-2 positive, 438 (0.6%) with severe COVID-19 illness, and 45 (0.06%) COVID-19-related deaths. After exposure-driven propensity score matching, patients with pre-existing HSI-NAFLD, FLI-NAFLD, or claims-based NAFLD had an 11–23% increased risk of SARS-CoV-2 infection (HSI-NAFLD 95% confidence interval [CI], 1–28%; FLI-NAFLD 95% CI, 2–27%; and claims-based NAFLD 95% CI, 2–31%) and a 35–41% increased risk of severe COVID-19 illness (HSI-NAFLD 95% CI, 8–83%; FLI-NAFLD 95% CI, 5–71%; and claims-based NAFLD 95% CI, 1–92%). These associations are more evident as liver fibrosis advanced (based on the BARD scoring system). Similar patterns were observed in several sensitivity analyses including the full-unmatched cohort. Conclusion: Patients with pre-existing NAFLDs have a higher likelihood of testing SARSCoV-2 positive and severe COVID-19 illness; this association was more evident in patients with NAFLD with advanced fibrosis. Our results suggest that extra attention should be given to the management of patients with NAFLD during the COVID-19 pandemic.

Improved Outcome of Central Nervous System Germ Cell Tumors: Implications for the Role of Risk-adapted Intensive Chemotherapy

Yoo, Keon Hee,Lee, Soo Hyun,Lee, Jeehun,Sung, Ki Woong,Jung, Hye Lim,Koo, Hong Hoe,Lim, Do Hoon,Kim, Jong Hyun,Shin, Hyung Jin The Korean Academy of Medical Sciences 2010 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.25 No.3

<P>To determine the impact of treatment protocols on the outcome of central nervous system germ cell tumors (CNS-GCTs), we reviewed the medical records of 53 patients who received front-line chemotherapy from September 1997 to September 2006. Pure germinoma, normal alpha-fetoprotein level and beta-human chorionic gonadotropin level <50 mIU/mL were regarded as low-risk features and the others as high-risk. Patients from different time periods were divided into 3 groups according to the chemotherapy protocols. Group 1 (n=19) received 4 cycles of chemotherapy comprising cisplatin, etoposide and bleomycin. Group 2 (n=16) and group 3 (n=18) received 4 cycles of chemotherapy with cisplatin, etoposide, cyclophosphamide and vincristine in the former and with carboplatin, etoposide, cyclophosphamide and bleomycin in the latter. In group 2 and group 3, high-risk patients received double doses of cisplatin, carboplatin and cyclophosphamide. Radiotherapy was given after chemotherapy according to the clinical requirements. The event-free survivals of groups 1, 2, and 3 were 67.0%, 93.8%, and 100%, respectively (group 1 vs. 2, <I>P</I>=0.06; group 2 vs. 3, <I>P</I>=0.29; group 1 vs. 3, <I>P</I>=0.02). Our data suggest that risk-adapted intensive chemotherapy may improve the outcome of patients with malignant CNS-GCTs.</P>

‘새로운 제국주의’와 자본주의

유재건(Yoo, Jae-Keon) 부산대학교 한국민족문화연구소 2017 한국민족문화 Vol.64 No.-

신자유주의 시대로 일컬어지는 1970년대 이후 현재의 지구 자본주의는 과연 얼마나 새로운 것인가? 이 논문은 이를 ‘새로운 제국주의’ 개념으로 포착하는 맑스주의 지리학자 데이비드 하비의 이론을 고찰하고자 한다. 지리적 공간이 사회적 관계의 중요한 속성임을 강조해온 그는 자본의 과잉축적 과정에서 잉여를 흡수하기 위한 지리적 팽창과 공간적 재조직화에 주목해 왔다. 그의 ‘시공간적 조정’(spatiotemporal fixes) 개념은 만성적인 위기에 대응하며 존속하는 자본주의를 해명하기 위한 중요한 단서이다. 시공간적 조정과 더불어 그가 자본주의의 지구적 작동 방식에서 주목하는 것은 ‘약탈에 의한 축적’(accumulation by dispossession) 현상이다. 임금노동력을 창출하는 고전적 확대재생산을 통한 성장이 강력했던 1950~60년대와 달리 1970년대부터 지속적인 과잉축적의 문제를 해결하기 위해 그러한 시도가 강화되었다는 것이다. 오늘날엔 약탈에 의한 축적과 확대재생산을 통한 축적 간의 균형은 이미 전자 쪽으로 이동하고 있다는 것이 그의 진단이다. 약탈에 의한 축적은 하비가 맑스의 ‘본원적 축적’ 개념을 현대 자본주의로 확장하여 적용한 개념이다. 그는 맑스가 『자본』에서 묘사한 폭력적인 본원적 축적 과정이 자본주의 초기 역사에만 해당되는 것이 아니라 특정한 역사적 시기와 무관하게 존재해왔다고 주장한다. 그것은 정도의 차이가 있을 뿐 자본주의 역사에서 불가결한 일부였다는 것이다. 하비는 약탈에 의한 축적을 맑스의 본원적 축적과 구별하기는 하지만 실제로는 그 공통점을 강조하는 편인데, 다만 오늘날의 약탈에 의한 축적은 과잉자본 상황에서 이루어지고 있다는 점에서 훨씬 악성이라고 비판한다. 하비의 이론은 맑스주의자들로부터는 잉여가치 착취에 의한 자본축적의 문제를 경시하고 착취를 통해 이미 만들어진 잉여가치의 분배를 주로 문제삼는다고 비판받는다. 그러나 이런 비판이 하비의 입장, 즉 이제껏 자본의 유통과 가치의 실현을 도외시하고 생산에만 집중하는 통상적 인식의 문제점을 지적하고자 하는 그의 생각을 온전히 이해하고 있다고 보기는 어렵다. 하지만, 하비가 자본주의 분석을 끊임없는 축적 위기와 관련지어 설명하는 과정에서 자본주의의 전체적 역사과정을 어떻게 이해하는지는 분명치 않다. 1970년대 지구적 자본주의의 새로움을 강조하는 그의 역사인식에서 그 이전 수백년에 걸친 지리적 팽창의 역사가 어떻게 이해되는지, 자본주의적 근대로의 전환점이 16세기인지 18세기 후반인지 불분명하며, 자본주의의 단위를 일국사적으로 설정하는 데서도 한계를 보인다. 그는 G. 아리기의 영토주의적 권력논리와 자본주의적 권력논리의 구분법을 원용해 제국주의를 이해하고자 하지만 그 구분은 이론적 근거가 취약하다고 생각된다. 각기 다른 국가들이 각기 다른 제국주의를 만들어냄을 제시하기 위해 영토주의와 자본주의를 대등한 수준의 계기로 설정하는 것이 과연 설득력이 있을지 의심스럽다. This paper aims to examine the historical aspects of D. Harvey"s theory of "New Imperialism". The way he looks at the economic situations since the 1970s is to examine the role of "spatiotemporal fixes" to the inner contradictions of capital accumulation. He insists that imperialism as a certain form of the production of space was the answer to this riddle. Besides, he thinks that new mechanism of capital accumulation by dispossession became increasingly more salient after 1970s, as compensation for the chronic problems of overaccumulation arising within expanded reproduction. It"s interesting that his thoughts here is guided in part by a reconsideration of Marx’s theory of value and Marx"s concept of "primitive accumulations". His concept of capitalist imperialism is based upon G. Arrighi"s discourse on two logics of power, the territorial logic and the capitalist logic. He contends that they are different from each other. The two logics contrast in the motivations and interests of agents, and many other ways. Based upon the methodology of historical-geographical materialism, Harvey defines capitalist form of imperialism as a dialectical and contradictory fusion of two logics of power, but I think that two logics cannot make a dialectical pair.
