This study is to investigate economical efficiency of using ALWOOD Form compared with that of EURO Form. ALWOOD Form is improved in the capacity in the wall-concrete structure in stead of using the existing form which has problems such as, the loss of labor when it is constructed or disjointed, and it's economical efficiency compared with that of EURO Form. The price of ALWOOD Form is more expensive than that of EURO Form due to its main material, aluminum-compound metal, composing frames. In a consequence, the cost of materials per unit area is increased. However, labor cost of ALWOOD Form based on the result of mobilization of manpower in construction field is saved due to the reduction of labor in using ALWOOD Form compared with that of EURO Form. As a result, using ALWOOD Form is more economical than that of EURO Form because saving labor cost which plays a major part in cost saving in formwork is more effective in retrenching total cost than increment of material cost. 철근 콘크리트조 건축공사에서 거푸집공사는 전체 공사기간 중에서 25% 정도의 비중을 차지하며, 단일 공종으로서는 상당히 긴공기를 필요로 하는 공사이다. 따라서, 거푸집공사는 주공정 (critica1 path)이 되고 있으며, 구조체 공사비의 30-40%, 전체공사비의10% 정도를 차지하므로 공기단축과 원가절감을 도모하는데 핵심적인 위치를 차지하고 있다. 이러한 거푸집공사는 최근 건설현장의 기능인력 부족과 노무비 상승, 3D업종의 기피,공사규모의 대형화,고층화 등의 사회환경의 변화와 많은 기술환경의 변화에 따라 거푸집의 대형화, 경량화, 기계화, 단순화, Unit화 그리고 높은 전용횟수를 요구하게 되었다. 그러나 현재 RC조 고층 벽식 구조물의 거푸집 공법으로 범용되고 있는 시스템화 거푸집의 일종인 “EURO Form"은 중량이 커서 부재의 크기가 작고 해체, 조립의 반복에 따른 인력의 소모가 많으며, 이음부위 면처리 비용이 많이 드는 등의 단점이 있어 이에 대한 보완이 필요한 실정이다. 따라서 이러한 문제점을 개선하기 위해 비중이 낮고 성형성이 우수하여 합리척인 설계가 가능한 알루미늄 합금재 프레임을 이용한 거푸집공법(이하 ALWOOD Form 공법)이 개발되어 일부 건설현장에서 시범 적용중에 있으나 원가관리를 위한 기초 자료가 부족하여 그 적용이 곤란한 실정이다. 따라서 본 연구는 ALWOOD Form과 EURO Fonn의 공사바 비교 · 분석을 통해 건설현장에서 거푸집공법 선정시 원가관리 측면에서의 기초자료를 제공하는데 그 목적이있다.

Parallax 效果를 應用한 漸進的인 景觀演出에 關한 硏究

安奉遠,盧載鉉 경희대학교 1988 造景論叢 Vol.1 No.1

The purpose of this study is to create a design using plant for progressive realization. For this, the image structures of photo-sketch simulation for parallax landscape have been investigated by the factor analysis. Visual preferences measured by questionnaires were evaluated by Scenic Beauty Estimation, paired comparison method and the results could be summarized as follows. The results of semantic differential scale values for landscape through parallax were greater than non-parallax landscape. The scenes through parallax were better preference than a direct view. Thus the results of photo-sketch simulation test support the expected hypothesis that the visual environment of complexity and variety is closely correlated with the parallax effect and monotonouse or non-parallax environment. Factors covering the spatial image of parallax landscape were found to be seven and Total Values were 60.35%. The important factors determining the degree of visual preference were the distance to primary object, the harmony of trunks and primary object, the shape of screening trunks and the vista among the trunks yield high values for parallax landscape. In photo observation, the everage degree of screening was 38%, the range of degree of screening was 50-30%. In Sketch simulation, filtered pattern got the highest preference score and turned out to be the most practical pattern among the patterns evaluated. Also, in sketch simulation, the high preference values were observed in the cases of 9 to 12m of distance from the view point to screening tree and the D/H rato of 2. The preference score were significantly decreasing as the increase of screening having of turning point at 30-35% of screening, although the distance parameters were more important than the degree of screening in the preference score. An outstanding view must be handled properly to be preserved or accentuated. A framed, open, enclosed, screened or filtered views should be completely revealed only from its best vantage point, not given away of first glimpse. In this sense, the parallax spatial beauty with tree could be improved through the visual aspects of plan arrangements and the progressive realization appeared to be one effective design technique for landscape planning and design.

출생순위와 정신장애

석재호,안석철,손봉기 大韓神經精神醫學會 1978 신경정신의학 Vol.17 No.2

There have been many reports which dealt with the matter of incidence of schizophrenia, controlled by family size and sibling order. They got no uniform result but many of them suggested a possible relation between the schizophrenic incidence and the sibling order. Meanwhile the family size is getting smaller. Anticipation of this leads us to deal with the problem of mental hygiene in the small sized family. So the authors have chosen the mental patients who have two siblings, in the O.P.D. and the ward of Department of Neuropsychiatry of Han-Gang Sacred Heart Hospital from September 1976 to November 1977 to see the incidence of psychoses and neuroses among three siblings. The authors could sample 124 cases of psychotic and neurotic patients excluding patients with brain syndromes and 60 cases of organic brain syndromes, the control group. The results were as follows: 1. Among 29 psychotics, 12 were the first born, 7 the second born and 10 the third born. Among 95 neurotics, 30 cases were the first born, 37 the second born and 28 the third born. No significant difference was noted among these features. 2. In the subgroups of one son and two daughters, 3 brothers, and 3 sisters, no siginificant relationship in incidnece of mental disorder could be found. 3. In the subgroups of two sons and one daughter, the incidence of neurosis was significantly high in females. 4. In the group of organic brain syndromes, there was no significant difference in the incidence of psychosis and neurosis among different sibling orders.

움직임 예측을 위한 비트패턴을 이용한 고속 워핑 예측

강봉구,윤태승,곽내정,안재형 충북대학교 컴퓨터정보통신 연구소 2002 컴퓨터정보통신연구 Vol.10 No.2

본 논문에서는 비트패턴을 이용한 고속 워핑 예측을 제안한다. 워핑 예측은 이웃한 노드들의 움직임 벡터에서 움직임 정보를 가져오는 공간적인 의존성 때문에 최적의 움직임을 찾기 위해서는 반복적인 탐색을 요구한다. 반복적인 탐색에 의해 발생하는 연산량의 증가는 워핑 예측의 사용을 저해하는 큰 이유 중의 하나이다. 본 논문에서 제안한 방법은 비트패턴을 이용해서 움직임 여부를 판단한다. 움직임이 없는 영역에서의 의미 없는 움직임 예측을 제거하고, 움직임이 있는 영역에서만 워핑 예측을 수행함으로써 빠른 움직임 예측이 가능하게 된다. 제안된 방법으로 실험한 결과 기존의 워핑 예측을 수행했을 때보다 성능은 근접하면서도 연산량이 75% 이상 감소하였다. In this paper, we propose a fast warping prediction using bit-pattern. Because of the spatial dependency between motion vectors of neighboring node points carrying motion information, the optimization of motion search requires an iterative process. The computational load stemming from the iterative search is one of the major obstacles for practical usage of warping prediction. The motion estimation in the proposed algorithm measures whether the motion content of the area is or not, using bit-pattern. Warping prediction using the motion content of the area make the procedure of motion estimation efficient by eliminating an unnecessary searching process. Experimental results show that the proposed algorithm can reduce about 75% of iterative search while maintaining performance as close as the conventional warping prediction.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.
