The authors assessed if there is a relationship between joint effusion and the presence of pain, and between joint effusion and disc displacement in 446 temporomandibular joints of 223 subjects who visited the Department of Oral Medicine, Kyungpook National University Hospital with the complaints of temporomandibular joint problem. The amount of joint effusion and the position of disc were determined from magnetic resonance images of the temporomandibular joints. The position of disc was classified into normal disc position, disc displacement with reduction (DDWR), and disc displacement without reduction (DDWOR). The amount of joint effusion was graded according to the extent of joint area of high signal intensity on T2-weighted MR images. These findings were correlated with one another and statistically analyzed. The results were as follows; 1. The incidence of temporomandibular joint pain Was higher in the joints with higher amount of joint effusion (P<0.001). 2. The proportion of temporomandibular joints with higher amount of effusion increased in the joints with more advanced articular disc displacement (P<0.001).

Purpose: MAT-I/III deficiency by MAT1A gene mutation causes isolated hypermethioninemia, which is considered to be a clinically benign disease. But in some patients, mental retardation, developmental delay, myelination disorder may be shown. This study was performed to find out the clinical manifestations and genetic characteristics of patients with isolated hypermethioninemia. Methods: Clinical, biochemical and genetic analysis were done to 10 patients with isolated hypermethioninemia who were referred to department of pediatrics, Soonchunhyang University Hospital from March 1999 to March 2012. Results: At first visit, all patients' mean plasma methionine level was 5.5 mg/dL (2.1-14.6) and there were no increase of amino acid levels including homocystine in all patients. Serum homocysteine level was evaluated in seven patients who visited after year 2003, and ranged from 4.96 to $11.15{\mu}mol/L$ (normal < $25{\mu}mol/L$). Methionine restricted diet was started to all patients. Nine patients who managed regularly showed normal development, but one patient whose initial plasma methionine level was 14.6 mg/dL showed language delay at 1 year of age and was diagnosed as mild mental retardation (IQ=66) at 6 years of age. Genetic analysis was done to eight patients, R264H mutation was identified in seven patients. Also, both R299C and R356Q mutation were identified in one patient. Conclusion: Clinical findings in patients with isolated hypermethioninemia were generally good, but one patient showed mental retardation and language difficulty. R264H mutation which usually inherits as an autosomal dominant trait was most frequently found in our patients, and R299C/R356Q mutation were also identified.

5·16 군사정부의 공보

유상수(Yu Sang-Soo) 역사실학회 2012 역사와실학 Vol.47 No.-

This paper deals with the public information policy among a variety of policies established after the establishment of the May 16 military government. A public information policy is originally for promoting a government's numerous activities, but the one during the military regime after the May 16 coup went beyond the negative meaning, carrying a positive meaning of securing legitimacy. The public information policy was closely associated with the stages of the revolution planned by the leading forces of the coup as the policy was considered a tool for realizing the plan. They asserted the eradication of the old evils as 'the first stage.' Then as 'the second stage,' they carried out organizational reforms with the purpose of strengthening the economic development and anticommunism that they had emphasized. During these processes, the public information organization was expanded in comparison with that of the previous governments. As the tasks for 'the third stage' needed to be performed along with the completion of the 'second stage' tasks by July 1961, the characteristics of the public information policy changed. The tasks for 'the third stage' were to be newly carried out by the leading forces of the coup. The public information policy until 1962 was implemented while this 'third task' tasks were established. The reinforcement of publicity activities and broadcasting for farming and fishing communities, the promotions of culture and arts, and the expansion of foreign publicity activities were aimed at the 'third stage' tasks. The 'third stage' tasks included public enlightenment and guidance through publicity activities, which were based on a perception that 'the leading forces of the revolution' should lead the general public with reformist inclinations and new ideologies for Korea to develop into a advanced nation. The military government's public information policy developed in this wise did not appear to be effective. This is because it was not smoothly done to transfer power to civil government for the continuity of all of the policies developed by the military regime. A bill for constitutional amendment was put to a plebiscite on December 17, 1962. The Office of Public Information conducted a public opinion poll focused on those who favored the bill on January 12, 1963, and the results showed immense support for the military government and President Park Chung-Hee. Nevertheless, President Park won the presidential election in 1963 by a narrow margin, only 150,000 votes, in spite of the advantage of staying in power. This result indicates that public support for President Park and the military government was actually low and that the outcomes of the public information policy aggressively pursued by the military regime proved not to be effective.

학술연구 : 우회상장 결정요인에 관한 실증연구: 한국 코스닥시장을 중심으로

유상수 ( Sang Soo Yoo ),양동우 ( Dong Woo Yang ) 한국중소기업학회 2011 기업가정신과 벤처연구 Vol.14 No.4

본 연구는 상장예정인 비상장기업의 어떠한 특성이 상장방안으로서 우회상장 또는 IPO의 선택에 영향을 미치는지 연구하고자 한다. 이를 위해 2001년부터 2009년까지 코스닥 시장에서 우회상장을 한 186개, IPO를 한 522개 비상장기업을 대상으로 분석을 수행하였다. 특히 상장형태의 선택에 영향을 미치는 결정요인으로서 비상장기업의 영업기간, 기업규모, 부채비율, 수익성(자산수익률, 영업현금흐름, 경상이익률), 경영자의 연령, 벤처캐피탈의 투자지분율 및 투자여부 변수를 사용하였다. 연구결과 상장예정기업의 영업기간이 길수록, 기업의 규모가 작을수록, 부채비율이 높을수록, 수익률이 낮을수록(자산수익률, 영업현금흐름, 경상이익룰), 상장당시의 경영자의 연령이 낮을수록 IPO보다는 우회상장을 선택할 확률이 높은 것으로 나타났다. 또한 기관투자자로서 벤처캐피탈이 투자를 하는 경우에는 우회상장보다 IPO를 선택할 가능성이 높은 것으로 나타났으며, 벤처캐피탈의 투자지분율은 상장형태의 결정에 유의한 영향을 미치지 못하는 것으로 나타났다. 특히 영업기간이 길수록 우회상장을 선택할 가능성이 높게 나타났다는 것은 코스닥 시황과 상장관련 규제로 인해 불필요한 IPO 관련 비용을 줄이기 위한 의사결정의 결과라 해석된다. 또한 벤처캐피탈이 상장예정기업에 투자를 하면 IPO의 가능성이 높게 나타났다는 점은 벤처캐피탈이 반드시 고위험 고수익을 추구하지 않으며, 투자성향에 차이가 있을 수 있음을 시사한다. 추가로 본 연구는 우회상장의 결정요인 변수로 경영자의 인적특성 변수인 상장당시의 연령을 고려하였다는 점에서 선행연구와 차별점이 있다. 우회상장을 통해 부실한 기업이 상장 후 도산을 한다면 선의의 투자자들이 입게 되는 기대손실과 자본시장의 파급효과는 상당할 것이다. 이에 우회상장을 중심으로 상장형태의 결정요소에 대한 본 분석은 의미가 있다. In this study, we examine the determinants of back-door listing in South Korea Stock Market by using 186 firm-year observations of back-door listing firms and 522 firm-year observations of initial public offering firms provided by DART (Data Analysis, Retrieval and Transfer System) data base from 2001 to 2009. And we used the firm-age, firm-size, debt-to-equity ratio, profitability(return on assets. cashflows from operating income, ordinary income ratio), age of CEOs when firms` going public and investments of venture capitals as the possible back-door listing determinants. As a result, firms that have longer firm-age, smaller firm-size, higher debt-to-equity ratio, less profitable and younger of CEOs` age have higher probability of choosing of back-door listing than choosing of initial public offering when they are going public. Also investment of venture capital as an institutional investor increases the probability of IPO but we can not find any significant relationships between the percentage of venture capital investment and the type of listing. The results imply that investors should give additional consideration to the firm characteristic when they make investment decision for newly listed firms by back-door listing.

Headache with Dural Thickening on MRI as an Initial Presentation of Leukemia: A Case Report

유상수(Sang Soo Yoo),서은숙(Eun Sook Suh) 대한소아신경학회 2012 대한소아신경학회지 Vol.20 No.4

두통은 일차성과 이차성의 두 가지로 분류할 수 있다. 이차성 두통은 중추신경계 또는 다른 원인에 의한 두통을 의미하며, 이차성 두통의 원인에 따라 환아를 사망에 이르게 할 수 있다. 저자들은 급성, 지속성 두통으로 내원한 환아의 MRI 영상에서 경막 비후를 보인 증례를 소개한다. 경막의 생검 결과 전구 B세포성 림프모세포 림프종이 확인되었다. 환아는 급성 림프모구성 백혈병을 진단받았고 두통은 급성 백혈병의 첫 증상이었다. 이 증례에서 보는 바와 같이 이차성 두통에 대한 가능성을 염두에 두고 원인을 밝혀내려는 노력이 중요하며, 두개 내 병변이 의심되는 병력이나 비정상적인 신경학적 진찰을 보이는 환아에게는 영상학적 검사가 고려되어야 한다. Headache can be divided into two categories: primary and secondary. Secondary headaches are associated with central nervous system or other pathology, and the underlying cause of a secondary headache can lead to death. For that reason, a thorough history and examination is key to determining the cause of headache. Other investigations including neuroimaging studies should be strongly considered in children with a history worrisome for intracranial pathology or an abnormal neurologic examination. We present a case of headache with diffuse hypertrophy of the dura mater due to lymphomatous dural infiltration. MRI revealed diffusely enhancing dural thickening. Biopsy of the dura mater found precursor B-cell lymphoblastic lymphoma. The patient was diagnosed with acute lymphoblastic leukemia and the headache was the initial presentation of acute leukemia. In this case, the rapid expansion of the dura mater resulted in elevation of intracranial pressure and caused an acute onset, progressive headache.

조작간첩사건 이후 ‘간첩’의 삶 - ‘울릉도간첩단사건’ 피해자를 중심으로 -

유상수(Ryu, Sang-soo) 동국역사문화연구소 2021 동국사학 Vol.72 No.-

이 논문은 조작간첩사건 이후 피해자들이 ‘간첩’이 된 후 어떤 삶을 살아왔는지 살펴본 글이다. 그 중에서도 1970년대 대표적인 조작간첩단사건인 ‘울릉도간첩단사건’의 피해자들의 목소리를 통해서 살펴본 글이다. ‘을릉도간첩단사건’은 1974 년 중앙정보부에서 울릉도 거점 간첩단 사건으로 발표한 사건이었다. 박정희 정권은 유신반대운동을 저지하기 위한 방법의 하나라 통혁당 사건을 능가하는 간첩단사건을 조작했다. 그 과정에서 관련도 없는 울릉도의 월북자가족과 전라북도 출신인사들을 연결시키며 ‘울릉도간첩단사건’을 만들어냈다. 이런 무리한 연결을 합리화하기 위해 수사단계부터 불법구금, 고문 등으로 허위자백을 받아내고, 이를 통해 사형부터 징역형에 이르는 판결을 끌어냈다. 이 사건의 피해자들은 법에 의한 형벌 뿐만 아니라 사회적인 낙인, 보호관찰, 연좌제 등의 부당한 고통을 받았고, 그 과정에서 가족 및 고향에 대한 여러 생각을 갖게 되었다. 이 글에서는 피해자들의 구술을 중심으로 피해자들이 법 이외의 방식들로 인한 고통 및 그 과정에서 느꼈던 여러 가지 생각들을 살펴보았다. This study investigates how the victims of fabricated spy case have lived after the incidents, focused on the Ulleungdo Case in 1970s. In 1974, South Korean Central Intelligence Agency relased this case as Ulleungdo base for North Korean Spy Group. Park Chung-hee regime fabricated a North Korean spy group case that is much bigger that TongHyeockDang case, in order to put a restraint on anti-Yushin movement. In that process, they created a false link between Ulleungdo Spy Group and social elites from Jeollabuk-do area, which had not a single connection. In an attempt to rationalize this unreasonable connection, they illegally detained the victions and tortured them which lead to false confessions, which got penal servitudes and death penalties. The victims unjustly suffered from not only the punishments under the law, but also the social stigma, probation and guilt by association, and many thoughts on families and hometowns were racing through their heads along the way. This article examines how they suffered in many ways besides law and their thoughts during the course based on their oral statements.

Magnetic phases of polycrystalline Ge<SUB>1 ? x</SUB>Mn<SUB>x</SUB> thin films were studied. The Ge<SUB>1 ? x</SUB>Mn<SUB>x</SUB> thin films were grown at 400 ℃ by using a molecular beam epitaxy. The Ge<SUB>1 ? x</SUB>Mn<SUB>x</SUB> thin films were p-type and electrical resistivities were 4.0 × 10<SUP>?2</SUP>~1.5 × 10<SUP>?4</SUP> ohm-㎝. Based on the analysis of magnetic characteristics and microstructures, it was concluded that the ferromagnetic phase formed on the Ge<SUB>1 ? x</SUB>Mn<SUB>x</SUB>/SiO₂/Si(100) thin films was Ge₃Mn? phase which has about 310 K of Curie temperature. Moreover, the Ge<SUB>1 ? x</SUB>Mn<SUB>x</SUB> thin film which had Ge₃Mn? phase showed the negative magnetoresistance to be about 9% at 20 K when the magnetic field of 9 T was applied.
