Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Poly(p-phenylenesulfide)와 poly(p-phenylene)으로부터 제조된 탄소를 리튬이온 2차전지용 음극재료로 사용하여 전기화학적특성을 연구하였다. 이들 고분자들을 질소 분위기하에서 승온속도 2℃/min로 1000℃까지 상승시킨 후, 1시간 동안 탄화시켜 탄소를 제조하였다. Poly(p-phenylene)으로부터 제조된 탄소가 보다 더 규칙적인 구조를 가지기 때문에 Poly(p-phenylenesulfide)으로부터 제조된 탄소보다 더 많은 용량과 충방전 효율을 나타내었다. 수산화리튬과 염화주석(Ⅱ)을 첨가하여 용량의 증가와 충방전 효율의 증가를 가져올 수 있었다. 이중에서 poly(p-phenylene)에 염화주석(Ⅱ)을 첨가시켜 제조된 탄소가 가장 큰 충방전 용량과 충방전 효율의 향상을 가져왔다. Carbon inaterials manufactured from poly(p-phenylene sulfide) and poly(p-phenylene), were studied on electrochemical characteristics as anode materials for lithium ion secondary battery. These polymer precursors were heat treated for 1hr at 1000℃ with the rate 2℃/min under nitrogen atmosphere. Carbon manufactured from poly(p-phenylene) showed higher capacity and coulomb efficiency of charge/discharge than carbon from poly(p-phenylene sulfide) because the former has better ordered structure. Carbon manufactured from polymer precursors adding stannous chloride or lithium hydroxide showed higher capacity and better efficiency of charge/discharge. Also, carbon manufactured by adding stannous chloride to poly(p-phenylene) showed the highest capacity and efficiency of charge/discharge.

The purpose of the present study was to investigate the relationships among the contact frequency of homosexual lewd materials, homophobia, and prejudice against homosexuals of adolescents. A survey was carried out to 389 middle school students in Gyeonggi province. The brief summary of the survey is as follows. First, among 389 subjects the 73.0% had contacted homosexual lewd materials during the last 1 year, and more boys than girls contacted lewd materials. Most of the subjects had watched the internet sex movies. Movies, TV shows, the papers for adults, and sexual photos were also homosexual lewd materials that many of the subjects had watched. The kinds of materials that middle school students have contacted were different based on sex. Boys contacted the internet sex movies while girls contacted fanfic most. All of them had experience to watch movies and TV shows frequently. Second, the results of regression analysis revealed that the relationship between the contact frequency of homosexual lewd materials and homophobia did not show any statistically significant correlation. However, girls showed statistically significant negative correlation between the contact frequency of homosexual materials and homophobia. Third, the results of regression analysis indicated that the relationship between the contact frequency of homosexual lewd materials and prejudice against homosexuals showed statistically significant positive correlation.

유주현,홍순석,박창엽 연세대학교 산업기술연구소 1986 논문집 Vol.18 No.2

PLZT electrooptic ceramics of compositions in the range X/65/35 with 5?? X ??9, where X is the mol % La substixuted for lead in a ceramic with a Zr/Ti ratio of 65/35, were fabricated by the two stage sintering technique. For the ceramics, dielectric properties and phase transition were investigated. X-ray diffraction analysis was performed to analize α-β phase transition. For X=5,6, its crystal structure was Rhombohedral in the thermally depoled state as well as the poled state. For 6〈X〈9, phase transition was occured by poling and the intermediate region existed between the paraelectric and ferroelectric states. For X=9, its crystal structure was the same cubic phase in the thermally depoled state and the poled state.

유주환 永同大學校 2001 硏究論叢 Vol.7 No.1

강우에 계절적 변동이 크고 유역면적이 작아 수자원 확보에 불리한 환경을 가진 우리나라는 용수수요의 증가에 따라 댐을 증축하여 수자원을 확보하고 있는 실정이다. 이 때문에 형성된 복합 저수지군의 규모와 관리의 중요성은 점차 커져왔다. 이때 저수지 유입량을 산정하는 것은 수자원 관리의 기본이 된다. 특히 복합 저수지군의 각댐 유입량에는 상류댐의 유입량이 포함되어 있지만 수자원의 효율적 관리를 위한 시스템 분석 등에 자기유역 유입량의 산정이 기초가 된다. 이에 본 연구에서는 상류댐 유입량을 포함한 댐 관측 유입량으로부터 각 댐별 자기유역 유입량을 산정하는 방법을 제시하고 수계내 저수지별 유입량을 산정하고 그 적정성을 검증하였다. In our country which has the inferiority that the rainfalls in its area are much fluctuated due to the seasons and its drainage area is small the water resources has been stored by means of making additional dams as water demands increase. And the importance of the scale and management of multiple reservoir system becomes larger. So the calculation of the reservoir inflows is fundamental for the management of the water resources. Especially the calculation of the individual lateral inflow into each dam of the multiple system is basic on the system analysis for the effective management of water resources. Therefore in this study the methodology which can calculate the amount of the lateral inflow into individual dam using the registered dam inflow data involving the upstream dam inflow was suggested and its fitness was verified.

나주영,김명국,유봉구 고신대학교 의과대학 2010 고신대학교 의과대학 학술지 Vol.25 No.2

Pontine tegmental hemorrhage involving the trigeminal tract, the medial lemniscus, and the spinothalamic tract frequently give rise to various sensory dysfunctions. However, isolated hypesthesia confined to certain parts of trigeminal sensory dermatomes is very rare. We experienced a case of impairment of pain and temperature sense over the unilateral ophthalmic (V1) and maxillary (V2) nerve distribution. Brain CT and gradient echo MRI showed a small hemorrhage in the right dorsomedial midpons. The segmental sensory impairment may explain by somatotopic representation of trigeminal nucleus and tract in the ventral to dorsal and cranio-caudal direction

사법경찰관의 수사주체성에 관한 연구

유주성 치안정책연구소 2011 치안정책연구 Vol.25 No.2

1954년 형사소송법 제정 이후, 검사는 범죄수사의 주재자로서 수사권에 관한 독점적 권한을 가지고 있었던 반면 사법경찰관은 독자적인 수사권을 가지지 못한 검사의 수사상 보조자에 불과하다는 것이 판례와 학설의 지배적인 입장이었다. 검사는 지휘(묵시적 지휘 포함)를 통해 사법경찰관에게 자신의 권리를 위임하고, 사법경찰관은 검사의 포괄적 지휘권 내에서만 범죄수사를 개시·진행할 수 있었던 것이다. 현행 형사소송법 제195조에서 검사는 범죄의 혐의가 있다고 사료하는 때에는 수사를 하도록 하고 제196조에서 사법경찰관은 검사의 지휘를 받어 수사하여야 한다고 규정하여 모든 수사를 함에 있어 검사의 지휘를 받아 하도록 하고 있었다. 반면 최근 개정을 통하여, 형사소송법 제196조 2항은 '사법경찰관은 범죄의 혐의가 있다고 인식하는 때에는 범인, 범죄사실과 증거에 관하여 수사를 개시·진행하여야한다'고 규정하여 검사의 지휘가 없더라도 사법경찰관이 수사를 주체적으로 개시·진행할 수 있는 근거조항을 마련하였다. 이와 동시에 제196조 1항에서 사법경찰관은 '모든 수사에 관하여 검사의 지휘를 받는다'고 규정하고 196조 3항에서 '검사의 지휘가 있을 때에는 이에 따라야 한다'고 명시하여 사법경찰관에 대한 검사의 수사지휘권 또한 분명하게 재확인 되었다. 더욱이 검사의 수사지휘에 관해 구체적인 사항을 경찰, 검찰 양 기관의 합의에 따라 대통령령으로 규정하기로 함으로써, 사법경찰관의 수사주체성을 공고화하는 문제와, 검사 수사지휘권의 범위와 한계를 합리적으로 조정하는 문제가 공론화될 수 있는 장이 마련되었다. 이 논문은 장차 대통령령 제정 시 관련논의를어떻게 발전시켜나갈 것인가에 대해 큰 틀에서 근본적으로 고민해보고자, 나아가 대통령령 제정 이후 지속되어야 할 '수사권조정'의 합리적인 방향설정을 위해, 형사소송법 등 개정의미와 사법경찰관의 수사주체성에 관하여 법리적, 실무적 해석론을 중심으로 살펴보았다. Depuis la mise en place du Code de la procédure pénale en 1954, le procureur est le 《maitre》 de l'enquête criminelle, possédant un monopole du pouvoir d'enquête. Avant les modifications du Code en juin 2011, l'officier de police judiciaire n'avait aucun pouvoir propre d'enquête, et n'était qu'un auxiliaire du procureur dans l'accomplissement de l'enquête criminelle : le procureur déléguait son pouvoir d'enquête à l'officier de police judiciaire, qui sous sa direction, menait l'enquête criminelle. Ainsi, les articles 195 et 196 du Code énonçaient comme suit. Art.195 (Enquête du procureur) 《 Dans la mesure où le procureur public apprécie le fait qu'il y ait une infraction commise, il doit mener l'enquête criminelle sur l'infraction, son auteur et les preuves de l'infraction. 》 ; Art.196 (L'officier et l'agent de police judiciaire) 《 1° En tant qu'officier de police judiciaire, le contrôleur général de police, le commissaire général de police, le commissaire de police, le commandant de police ou le lieutenant de police doivent, après avoir reçu la directive du procureur, mener l'enquête criminelle ; 2° En tant qu'agent de police judiciaire, le brigadier de police et le gardien de paix doivent seconder l'enquête criminelle sous la direction de l'officier de police judiciaire ou de celle du procureur 》. Dans le contexte de 《 la réforme du parquet 》, l'Assemblé nationale a accordé récemment, à la grande majorité, de renforcer le rôle de l'officier de police judiciaire, lui donnant un propre pouvoir d'enquête jusque là exclusivement possédait par le procureur. Ainsi, désormais, l'officier de police judiciaire a la charge de déclencher et mener l'enquête criminelle de manière 《 autonome》, sans attendre une directive du procureur. Cependant, les législateurs n'ont pas retiré le droit de direction du procureur au cours de l'enquête menée par l'officier de police judiciaire. L'article 196 du Code a été modifié comme suit. 《1° En tant qu'officier de police judiciaire, le contrôleur général de police, le commissaire général de police, le commissaire de police, le commandant de police ou le lieutenant de police reçoit la directive du procureur pour toute enquête criminelle ; 2° Dans la mesure où l'officier de police judiciaire prend la connaissance d'une infraction commise, il doit déclencher et mener l'enquête criminelle sur l'infraction, son auteur et les preuves de l'infraction:3° L'officier et l'agent de police judiciaire doit respecter la directive du procureur. Les dispositions relatifs au droit de direction du procureur seront réglées par un décret présidentiel ; 4° En tant qu'agent de police judiciaire, le brigadier de police et le gardien de paix doivent seconder l'enquête criminelle(…) 》. Les deux organes d'enquête, le parquet et la police sont chargé de préparer le projet du décret présidentiel portant sur les dispositions relatives au droit de direction du procureur : il s'agit là d'une véritable occasion pour, enfin, équilibrer les pouvoirs de ces organes d'enquête dans la phase préparatoire de la procédure pénale.
