Objectives : Euthymic patients with bipolar disorder have been reported to show deficits in sustained attention. This study aimed to compare the attention capacities of euthymic bipolar patients with those of control subjects using the sustained att-ention to response task (SART) and to examine the differences in the performance of SART related to the type of the stimulus. Methods : The four SART tasks were performed to measure attention capacities in 42 euthymic patients with bipolar dis-order and 28 control subjects. Happy, neutral, fearful faces and digit '3' were used as target stimuli in happy, neutral, fear and digit task conditions, respectively. The seventy of mood symptoms was assessed with 17-item Hamilton Rating Scale for De-pressive symptoms and Young Mania Rating Scale for manic symptoms. The efficiency estimate which reflects both the res-ponse accuracy and speed was used as the main outcome variable. Results : Bipolar patients showed significantly lower correct response rate than control group in all task conditions. Effi-ciency estimates of the bipolar patient group were significantly lower than those of the control group in the SART using facial stimuli, but not in the digit task condition. There was no significant difference in task performances related to the emotional categories of facial stimuli. Conclusion : Bipolar patients showed deficits in sustained attention even in the euthymic state. The attention deficits shownin the euthymic bipolar patients may be prominent in a more complex task condition with stimuli such as facial stimuli.

Installation periods of implants in Mx. and Mn., is related to pattern of bone formation. The purpose of this study was to observe histologic response in osseointegration at root formed implanttissue interface at Mx. and Mn., the other is comparison of osseointegration level between Mx. and Mn. at 8 weeks. In this study, unilateral upper & lower molars were extracted in dog. After allowing to heal for 4 months, two kinds of osseointegrated implants Swedevents, Corvents-were inserted in dog. The specimens were treated by conventional method. The interface zones between bone and implant were investiigated using X-rays, light microscope. The following results were obtained from this study. 1. Around titanium implants that were installed in Mx. and Mn., Radio lucencies don't exist. 2. There are not inflammation and mobility of titanium implants that were installed in Mx. and Mn. Most of implant surface are covered by bony tissues, partly by bone-marrow tissues. 3. Titanium implants installed in Mx., in contrast to same implants in Mn., shows more coverage by bone marrow tissue and lack of apposition lamellar bone, which lead to the assumption that bone formation in Mn. is faster than in Mx.

The purpose of this study was to investigate longitudinal growth and development of young children and follow-up effects of the educare program in the PNU Day Care Center. Particularly, the first objective of this second report of study was the comparison the entire domains of development with age between the Oct. of 1995 and the Dec. of 1998. The second objective was to analyze the developmental .changes of 5 children who entered the center in 4 years old since Oct. 1995. The subjects of this study were 448 children(241 boys, 207 girls). The instruments of this study were the KISC and KEDl-WISC(for intelligence test), the Learning Readiness Test, the Social and Emotional Scale, Height Scale and Weight Scale( for physical growth). The tests were carried out 2 times per year (the early of the year and the late of the year). Results from comparsion across the 1st through 7th tests during 3 years indicated that the mean of the height was increased about 1-8cm for all of 2-5 years old children. The mean of the weight also was increased about 1.5-4.0kg except 2 years old children. The intelligence score (T score) by KISC was increased around 6-42 points except 6 years old boys and girls. In the intelligence score by KEDl, there was improvements of average 8 points for 7 years old children. In the learning Readiness Test of 5, 6 years old children, the scores all of children except 6 years old girls got were decreased. The scores of 6 years old girls were incresed 6 points in the Dec. of 1998. In the Social and Emotional Scale, there was big improvement of scores between in the 1st test and in the 7th test. These results were discussed in the view of sample size, developmental characteristics, test instruments and educare program of the PNU day care center.

The interactions between nutrition and the endocrine system are more intimate and complex that previously thought. Nutrition modulates secretion and activity of many hormones, as part of the stress adaptation process. Fasting, in particular, produces a number of important changes in the endocrine system, with teleological purpose of helping the body tolerate the lack of food ingestion. These changes are therefore beneficial and protective, although at times they may not appear to be that way. The endocrine changes of fasting mediate the metabolic response. We must emphasize that these changes are completely reversible when appropriate nutrition is established. These changes are as followes: 1) decreased insulin and increased glucagon levels, 2) decreased thyroid effect, 3) decreased sympathetic activity, 4) hypothalamic hypogonadism, 5) decreased growth, 6) altered glucocorticoid secretion and metabolism, 7) impaired mineralocorticoid response, 8) decreased ADH secretion and effect. We experienced three cases of involuntary prolonged fasting after collapse of Sampoong department store. They were released from collapsed field after 11(case Ⅰ), 13(case Ⅱ), 17days(case Ⅲ) respectively. In each case, the endocrine changes of plasma levels were as followes: decrease of cortisol in case Ⅰ, increase of GH in case Ⅱ, decrease of free T3, T3, cortisol and increase of reverse T3, insulin in case Ⅲ. Each one did not show the same endocrine changes of plasma levels. But we think these changes of fasting are beneficial in metabolic response of human.

Purpose: Hepatorenal syndrome (HRS) is a fatal complication in patients with end-stage liver disease awaiting liver transplantation (LT). HRS often develops in patients with high model for end-stage liver disease (MELD) score. This study investigated the outcomes of peritransplant management of HRS in a high-volume LT center in Korea for 2 years. Methods: A total of 157 recipients that deceased donor liver transplantation (DDLT) from January 2017 to December 2018 were included. In-hospital mortality (IHM) was analyzed in relation to pre- and posttransplant application of renal replacement therapy (RRT). Results: Primary diagnoses for DDLT were alcoholic liver disease (n = 61), HBV-associated liver cirrhosis (n = 48), retransplantation for chronic graft failure (n = 24), and others (n = 24). Mean MELD score was 34.6 ± 6.2 with 72 patients at Korean Network for Organ Sharing MELD status 2 (45.9%), 43 at status 3 (27.4%), 36 at status 4 (22.9%), and 6 at status 5 (3.8%). Pretransplant RRT was performed in 16 patients (10.2%) that did not show IHM. Posttransplant RRT was performed in 69 patients (44.0%), for whom IHM incidence was 15.9%. In 53 patients that had undergone de novo posttransplant RRT, IHM incidence increased to 20.8%. IHM in the 88 patients not requiring RRT was 2.3%. Conclusion: The majority of adult DDLT recipients in Korean MELD score-based allocation system have very high MELD scores, which is often associated with HRS. Pretransplant RRT appears to improve posttransplant survival outcomes. We thereby recommend that, if indicated, pretransplant RRT be performed while awaiting DDLT.

효율적인 도로정보의 구축은 GIS에서 가장 중요한 주제이다. 본 논문에서는 도로정보를 자동으로 생성, 구축하기 위하여 모바일 매핑 기술과 영상인식 기술을 결합한 방법을 제안하였다. 모바일 매핑 시스템은 CCD 카메라, GPS, INS를 장착한 차량의 형태를 가지며, 취득한 영상에 나타난 공간객체의 좌표를 사진측량기법을 이용하여 계산한다. 모바일 매핑 시스템에 의한 공간객체 좌표추출과 데이터 구축은 자동화되지 않아 시간이 많이 드는 단점이 있다. 도로의 자동 인식은 영상인식 분야에서도 자동주행차량에 대한 연구의 형태로 진행되어 왔다. 그러나 영상인식에 기반한 방법들은 도로 차선에 적용할 경우 차선의 끊김 차량에 의한 가려짐 좋지 않은 날씨와 조명 등 실제의 도로나 도로변의 다양한 예외상황 때문에 원하는 결과를 얻기 힘든 경우가 많다. 이러한 단점을 보완하기 위하여 본 논문에서는 모바일 매핑 시스템으로부터 획득된 GPS/INS 데이터 및 영상인식 기술을 모두 이용한 자동 도로데이터 생성방법을 제안하였다. 영상에 나타난 도로 차선의 3차원좌표로부터 영상에서 객체가 나타날 위치를 추정하기 위한 방법을 고안하였으며, 이러한 방법은 도로 차선을 찾기 위한 복잡한 영상처리 과정을 대폭 줄일 수 있다. 예외상황 때문에 도로차선을 추출하지 못한 경우에는 스플라인 인터폴레이션에 의하여 값을 얻는다. 인터폴레이션은 교차로나 급격한 변화 지점에 따라 구분된 도로 구간 단위로 이루어진다. 본 논문에서는 제안된 객체좌표 추정방법과 인터폴레이션 기법에 대한 실험 및 결과를 제시하였다. VEfficient generation of road data is one of the most important issues in GIS (Geographic Information System). In this paper, we propose a hybrid approach for automatic generation of road data by combining mobile mapping and image processing techniques. Mobile mapping systems have a form of vehicle equipped with CCD camera, GPS, and INS. They can calculate absolute position of objects that appear in acquired image by photogrammetry, but it is labor-intensive and time-consuming. Automatic road detection methods have been studied also by image processing technology. However, the methods are likely to fail because of obstacles and exceptive conditions in the real world. To overcome the problems, we suggest a hybrid method for automatic road generation, by exploiting both GPS/INS data acquired by mobile mapping system and image processing algorithms. We design an estimator to estimate 3-D coordinates of road line and corresponding location in an image. The estimation process reduces complicated image processing operations that find road line. The missing coordinates of road line due to failure of estimation are obtained by cubic spline interpolation. The interpolation is done piecewise, separated by rapid change such as road intersection. We present experimental results of the suggested estimation and interpolation methods with image sequences acquired by mobile mapping system, and show that the methods are effective in generation of road data.

In the present study, we aimed. to consider the name of twelve main Meridian in order to understand the concept of the Meridian system and to applicate acupuncture theory in the clinical field properly and fundamentally. We referred to several literatures on the matter and we found out that the name of present twelve Meridian was not settled until the period of Yellow Emperor's Classic. In the time of Yellow Emperor's Classic, the two theory of Internal Organ and Meridian system were combined and added new theory of 'WoonGi'. The general rule of combination is that the component of name of Meridian consist of 'Hand' or 'Foot', 'three Eum and Yang' and internal organ. The internal organ coupled with the root ki or middle ki of 'three Eum and Yang' and the 'Hand' or 'Foot' depend on the location of internal organ that belongs to meridian. The name of Twelve Meridian is a kind of system formed to analyze the two concepts organically and dynamically. One is material internal organ and the other is immaterial meridian system.
