Seventy-one patients with complete hydatidiform mole were prospectively randomized into two groups: one group (39 patients) was treated with a single course of methotrexate and citrovorum factor rescue as chemoprophylaxis; the other group (32 patients) was not treated. After molar evacuation, four patients from the treated group (10.3%) and ten patients from the untreated group (31.3%) developed persistent trophoblastic disease. The time interval from evacuation of the mole to diagnosis of persi

BACKGROUND: Nowadays, a number of patients seeking cosmetic surgery for their sunken upper eyelid are increasing. The aim of this study was to provide an overview of the various treatment options for sunken superior sulcus with reported complications and to discuss effective methods for treatment. METHODS: In a PubMed search, studies involving patients undergoing correction of sunken superior sulcus with various treatment options were included. RESULTS: A systematic search revealed twelve articl

The adsorption of volatile organic compounds (VOCs) was carried out using an activated carbon fiber (ACF) filter in an automobile. The adsorption capacities of formaldehyde, toluene, and benzene on an ACF filter were far better than those of a polypropylene (PP) mat filter and combined (PP+activated carbon) mat filter by batch adsorption in a gas bag. In a continuous flow of air containing toluene vapor through an ACF packed bed, the breakpoint time was very long, the length of the unused bed wa

=목적: 35세 또는 40세 이상의 고령 산모에서 연령 및 연령과 관련된 산전 및 산후 합병증의 위험정도를 알아보고자 하였다.연구 방법: 1996년 이후 국내에서 발표된 35세 또는 40세 이상의 고령 산모에 대한 7편의 연구문헌에 대해 메타 분석을 실시하였다.결과: 35세 또는 40세 이상의 고령 산모에 있어서 출산 후 산모 및 신생아 상태는 전반적으로 양호하였다. 그러나, 연구군에서 대조군에 비해 임신 중에 임신 합병증 (조기분만, 태위, 임신성 고혈압, 임신성 당뇨병, 전치 태반, 조기 양막파수)과 자궁 근종, 출산 후 저체중아에 있어서 통계적으로 의의있게 높은 빈도를 보였다.

We investigated the effects of parametric synthesis conditions of catalysts such as sintering temperature, sorts of supports and compositions of catalysts on alignment and length-control of carbon nanotubes (CNTs) using catalyst powders. To obtain aligned CNTs, several parameters were changed such as amount of citric acid, calcination temperature of catalysts, and the sorts of supports using the combustion method as well as to prepare catalyst. CNTs with different lengths were synthesized as por

BACKGROUND: In the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus, we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities. METHODS: The study consisted of 13 premature infants who had a total of 14 cases of full-thickness skin defects of the extremities due to extravasation after tota

In order to define osteoporosis on the basis of bone mineral measurements, one must define an acceptable normal range or fracture threshold. It is clear that the normal range cannot be compared between different ethnic groups. We have measured spinal bone mineral density (BMD) by dual photon absorptiometry in 277 women without spinal fracture, aged 30-91 years, and in 53 women with asymptomatic spinal fracture to provide such a database for normal Korean women. Peak bone mass at the 3rd decade w

This study explored the portrayal of the self-integrity of the ethnic Bajau in the ritual theatre performance of igal. The study's objective is to confirm a portrayal of self-integrity between the ethnic practitioners and the audience through the ethnography method that emphasizes the link between behavior and culture. The theoretical applications of communitas and liminality are applied to analyze how both aspects display the self-integrity portrayal of the ethnic Bajau in the dramatic structur

Objective : This study was organized to find out whether there are differences between pregravid weight, body mass index, weight gain during pregnancy and birth weight in 1989 and 1999. Also it was designed to find out the factors which influenced the birth weight changes. Methods : A total of 725 (313 in 1989, 412 in 1999) pregnant women who had term delivery in the department of Obstetrics and Gynecology, Hanyang University Hospital were recruited for the study. Pregravid weight, body mass ind

The Korea Ministry of Environment prepares some paticulate matter eliminate measures for national health protection, as the Paticulate Matter (PM2.5) exceeds the standard at more than half of the monitoring posts installed in the nation's big cities. At the center of JeonJu, when measuring the ultrafine particles of inner car at the different driving conditions, at the condition of the Actuator of inner recirculation mode and the Blower of 2-speed, the reduction speed of the ultrafine particles
