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)

Object : This study was designed to examine the association between monocyte chemoattractant protein-l (MCPl) -2518poly morphism and major depressive disorder (MDD). Methods : Ninety patients with MDD and 114 healthy controls participated in this study. Genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism method. Results : Genotype and allele distributions in patients with MDD were significantly different from those of the controls, In particular, subjects with the allele A were found to have an increased risk of MDD. Conclusion : The present study suggests that the MCPl -2518 polymorphism may have a potential role for susceptibility to MDD in the Korean population and thus calls for consecutive studies in order to pile up the data with larger different ethnic background.

Background : During seasonal influenza epidemics and previous pandemics, pregnant women have been at increased risk for complications related to influenza infection. Although influenza vaccination has been widely recommended to pregnant women and immunocompromised hosts, the vaccination rate is presumed to be low in pregnant women. This study was aimed to evaluate the vaccination rate and factors associated with Influenza vaccination among pregnant women, who are at high risk for developing complications from the influenza. Materials and Methods : This study was carried out by telephone survey from April, 2007 to August, 2007. Women who were in their second trimester of pregnancy or above,- during October, 2006 and February, 2007, the recommended vaccination period, and had given birth at Inha University Hospital were selected as the study population. Immunization status, general understanding, and factors associated with vaccination were evaluated. Results : Among a total of 506 eligible pregnant women, 227 (44.8%) responded to the questionnaires. The influenza vaccination rate among the pregnant women was only 4% (9/227). Major reasons for not receiving vaccination were first, not awaring the necessity of immunization during pregnancy (48.5%, 110/227) and second, misunderstanding that it is prohibited during pregnancy (36.1%, 82/227). The major factors that influenced the compliance of vaccination were correct understanding and doctor's recommendation on the influenza immunization during pregnancy. Conclusions : The influenza vaccine coverage on pregnant women was very low and the awareness of influenza vaccination during pregnancy in general was inaccurate. Shift in perception is required and this can be achieved by educating the pregnant women on the safety and efficacy of vaccination. In addition, doctors' active encouragement to vaccination is highly recommended.

기립보행불능증 (astasia-abasia)은 양호한 근력과 운동기능을 가지고 있음에도 서거나 걷는 것이 불가능한 것을 말한다. 이것은 흔히 정신적인 질환으로 간주되지만 기질적인 원인들도 보고되고 있다. 보행영역은 근육과 말초 신경 뿐 아니라 전정-소뇌-시상-피질 연결고리의 되먹임 작용에 의한 연계가 필요하다. 우리는 길랑-바레 증후군을 가진 환자에게서 나타났던 기립보행불능증을 경험하였고, 신경염 과 함께 보행 영역 연결의 붕괴가 증상 발생과 연관이 있을 것으로 사료된다.

상당수의 사업체 조사는 절사표본설계법을 사용하고 있다. 이는 절사표본설계법에서 얻은 전수층이 많은 정보를 포함하고 있어 전체 표본크기를 최소화 할 수 있는 장점이 있기 때문이다. 그러나 최근 전수층에 포함된 사업체들의 무응답률이 높아감에 따라 전수층이 가지고 있는 장점에 한계가 나타나고 있다. 이에 Lee (2011), Shin과 Lee (2013)는 표본설계 단계에서부터 주어진 허용오차를 만족하면서 전수층 규모를 최소화하는 연구를 실시하였다. 본 연구에서는 주어진 허용오차를 만족하고 Hidiroglou (1986)가 제안한 방법으로 산출 된 표본크기를 고정한 상태에서 표본층 분산에 알려진 함수를 적합하여 전수층 크기를 최소화하는 새로운 최적 절사점을 제안하였다. 또한 Hidiroglou (1986)와 Shin과 Lee (2013)가 제안한 절단분포를 이용한 방법과 본 연구에서 제안한 방법을 모의실험과 사례연구를 통해 비교하였다. Modified cut-off sampling is widely used for highly skewed data. A serious drawback of modified cut-off sampling is the difficulty of adjustment of non-response in take-all stratum. Therefore, solutions of the problems of non-response in take-all stratum have been studied in various ways such as substitute of samples, imputation or re-weight method. In this paper, a new cut-off point based on minimizing MSE being used in exponential and power functions is suggested and it can be reduced the number of take-all stratum. We also investigate another cut-off point determination method with underlying distributions such as truncated log-normal and truncated gamma distributions. Finally we suggest the optimal cut-off point which has a minimum of take-all stratum size among suggested methods. Simulation studies are performed and Labor Survey data and simulated data are used for the case study.
