The main problems of computational complexity in object tracking were object definition, identification and segmentation in non-structured environments with erratic movements and object collisions. Therefore, for efficiency, we considered the object information as a region that corresponds to objects without discriminating among objects in the same frame. This paper describes the algorithm that, automatically and efficiently, recognizes and keeps tracks of interest-regions selected by a user in video or camera image sequences. The block-based feature matching method was used for region tracking. This matching process considers only dominant feature points such as corners , edges, bright and dark spots without requiring a pre-defined model of object s . Experimental results showed that matching process captured correct region successfully even when the objects undergo scaling and 3-dimensional movements in successive image sequences.

Titanium alloys have been mainly used for aircraft components as well as implant materials. Although a number of cutting tools and cutting methods have been developed for improving the cutting processes, they have difficulties such as tool wear and failure. This study considers a novel approach to on-line monitoring of tool wear and failure in titanium alloy cutting processes. The on-line monitoring system mainly consists of two parts: The one is on-line data acquisition with sensors and a DSP board through LabView and a web server, and the other is learning and prediction of tool wear and failure using an ART2 neural network algorithm. The system is installed at an on-site machine tool to monitor high speed steel(HSS) tools for cutting titanium alloy. A number of experiment are carried out to demonstrate the effectiveness of the proposed system.

본 연구의 목적은 피개교합 양상에 따른 성인 I급 부정교합자의 골격적 특징과 수직부조화를 야기하는 치성 및 골격성 요인들을 분석하기 위한 것이다. 서울대학교 치과대학 교정학교실에 소장되어 있는 정상교합군 표본 중 40명을 정상교합군, 서울대학교병원 교정과에 내원하여 I급 부정교합으로 진단받은 성인 환자중 전치부 수직피개량이 -0.1mm 이하인 40명을 개방교합군, 4.0mm이상인 40명을 과개교합군으로 선정하여 측모 두부 X-선 계측사진을 촬영하였다. 46개의 계측항목을 선정하고 SPSS program을 이용하여 각 군별 ANOVA, 판별분석, 다중회귀분석을 시행하여 다음과 같은 결론을 얻었다. 1.주로 하악골 형태와 하안면부의 치성, 골격성 요인이 수직부조화의 양상에 많은 영향을 끼쳤다. 2.개방교합군의 수직부조화 양상은 하안면부에서 두드러지게 나타났으며 하악골 형태와 하악하연평면 경사도와 관련이 있었고, 판별분석 결과 골격적 요인의 기여도가 높았다. 3.과개교합자의 수직부조화에는 주로 curve of Spee, 상악구치의 수직고경 등 치성 요인들의 기여도가 높았으며, 골격적 요인으로는 arcticular angle의 기여도가 높았다. 4.다중회귀분석 결과 I급 구치관계를 갖는 성인에서 overbite의 결정요인에는 주로 하악전치와 교합평면각, curve of Spee, 절치간 각도 등의 치성요인이 기여하였다. This study was investigated to evaluate the morphologic characteristics of openbite and deep bite in Class I malocclusion patients and to find skeletodental factors which contributed to vertical discrepancy in Class I malocclusion. The subjects were consisted of 40 control subjects (male 20, female 20) and 40 Class I openbite patients and 40 Class I deep bite patients. Lateral cephalograms in centric occlusion were taken, traced and digitized for each subjects. The computerized statistical analysis were carried out with SPSS program. The results were as follows. 1.The pattern of vertical discrepancy in Class I malocclusion is mainly influenced by the skeletodental factors under palatal plane. 2.In openbite group, vertical discrepancy is prominent on anterior lower face and is closely related with skeletal factors such as mandibular form and inclination. 3.In deep bite group, dental factors such as curve of Spee, vertical height of maxillary molar and skeletal factor such as articular angle were contributed to the vertical discrepancy. 4.The multiple regression analysis showed that overbite in Class I molar relationship was determined mainly by dental factors such as lower incisor to occlusal plane angle, curve of Spee, interincisal angle, and ODI.

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

Objective : The purpose of this study is to find out the effect of ApoE genotype in correlation between metabolic syndrome and cognition of the elderly in the community. Methods : A total of 1,305 subjects (440 men and 865 women) aged 60-98 years were analyzed from preliminary data of Gwangju Dementia and MCI Study (GDEMCIS). The metabolic syndrome was assessed as defined by the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III). The study questionnaire consisted of demographic characteristics, current and past illness history, drug history, family history of dementia and stroke, and Korean version-Mini Mental State Examination (K-MMSE). We also examined ApoE genotype and analyzed associated factors with metabolic syndrome. Results : Metabolic syndrome was present in 28.6% of the subjects (13.4% of men and 36.3% of women). On multiple logistic regression analysis, low serum HDL cholesterol was associated with an increased risk for cognitive impairment (K-MMSE score≤17) adjusted by age, sex, educational level, and smoking in the presence of ApoE ε 4 allele (OR 0.95, 95% CI 0.92-0.99). Conclusion : These results suggest that serum HDL cholesterol may affect cognitive function in the elderly in the presence of ApoE ε 4 allele.

An experiment was conducted to investigate the effects of forced molting and egg storage time on the various egg qualities. A total of 240 ISA Brown layers (60 wk of age) were employed as the unmolted treatment (Control). Two hundred and forty ISA Brown layers, molted at the age of 55 wk, were used as a forced molting treatment (T1), and the same number and strain of layers, molted at the age of 70 wk. were also used as the another forced molting treatment (T2). A total of 120 eggs were sampled from each treatment, and divided into six sets, 20 eggs per set. These six sets were stored for 1, 3, 6, 9, 12, and 15 days at 18℃ temperature, respectively. Eggs from T1 were collected from laying hens at the age of 68 wk, which started molting at 60 wk of age and achieved 50% egg production at 63 wk of age. Eggs from T2 were collected from hens at 82 wk of age, which started molting at 70 wk of age and achieved 50% egg production at 78 wk of age. The eggshell strength of T1 was significantly (p<0.05) higher than the Control and T2, and the storing periods did not affect the eggshell strength at all. Neither the forced molting nor the storing periods did not exert any consistent effect on the egg weight, eggshell thickness, eggshell color and egg yolk color. The albumin heights of T1 and T2 were significantly (p<0.05) lower than the Control, and it was remarkably reduced gradually as the storage periods increased in all three treatments. The Haugh unit showed very similar trends as the albumin height, indicating that both albumin height and Haugh unit were very much related to each other. In conclusion, the forced molting improves the eggshell strength, but decreases the albumin height and Haugh unit. The storage of eggs also decreases the albumin height and Haugh unit regardless of molting.

연구목적 : 외환위기 이후에 급증한 노숙자 문제는 경제적인 상황의 호전에도 불구하고 만성화하는 경향을 보이고 있다. 쉼터의 노숙자를 대상으로 정신질환의 유병율과 삶의 질에 대한 조사를 시행하였다. 방 법 : 2000년 3월에 서울의 대표적인 쉼터에 거주하는 노숙자220명을 대상으로 인구학적 자료에 대한 설문조사를 한 뒤 Structured Clinical for DSM-Ⅳ(SCID-I)을 이용하여 AxisⅠ의 주요 정신질환을 진단하였다. 또 SmithKline Beecham Quality of Life Scale(SBQOL)를 사용하여 삶의 질정도를 평가하였다. 결 과 : DSM-Ⅳ AxisⅠ의 정신질환 중 기분장애, 정신병적 장애, 물질 사용 장애에 대한 진단 평가 결과 상기정신질환의 전체 평생 유병율은 73.6%, 현재 유병율은 59.1%이었다. 알코올 의존과 남용의 평생 유병율은 59.5%로 가장 높았고, 기분장애와 장애가 각각 39.5%, 3.6%이었다. 삶의 질은 노숙의 기간이나 실직 기간과 유의한 관계가 없었고, 자신이 지각한 건강상태, 자살과거력, 우울장애 유무와 통계적으로 유의하게 상관관계가 있었다(p<0.01). 결 론 : 노숙자에서 정신질환 중 알코올 장애의 유병율이 가장 높았으며, 우울장애가 있는 경우에 삶의 질이 저하되는 것으로 나타났다. Objectives : Homeless people surged after financial crisis tend to be chronic despite late economic recovery. So we tried to estimate prevalence of mental illness and quality of life of the homeless population living in shelter. Method : The study subjects were 220 homeless peoples who stayed at a shelter in Seoul around March 2000. Questionnaires on sociodemographic data were administered to the subjects, and then diagnoses of major DSM-Ⅳ Axis I mental disorders were made using Structured Clinical Interview for DSM-Ⅳ Axis I Disorders(SCID). And quality of life(QOL) was evaluated by SmithKline Beecham Quality of Life(SBQOL). Results : The lifetime prevalence of major DSM-Ⅳ mental disorders(mood disorders, psychotic disorder, and substance use disorder) of 220 homeless people was 73.6%, and current prevalence was 59.1%. The lifetime prevalence of alcohol dependence and abuse was highest, 59.5% and those of mood disorder and psychotic disorder were 39.5%, 3.6% respectively. Quality of life was not significantly correlated with duration of homelessness and unemploy-ment but marital status, self perceive health status, suicidal attempt history were significant factors. The quality of life in the people with mood disorders were estimated to be lower than those with any other diseases(p<0.01). Conclusion : Alcoholism was the most prevalent mental disorder in homeless people and mood disorder was negatively related to the quality of life scale.
