이재광,김영혁,이재광 한국정보기술학회 2014 한국정보기술학회논문지 Vol. No.
탄소미터링 통합관제 시스템(Carbon-Integration Control System, CICS) 이란 IT 시설물의 에너지 사용현황을 실시간으로 확인하고 제어하는 기능을 가지고 있다. 기존의 CICS는 관제 모듈이 분산, 독립 운영되었으나 SmartRack 기반의 CICS는 항온·항습 센서, 공조기, PDU 등의 장치가 통합되어 전력사용량, 탄소배출량 등의 정보를 수집하고 수집된 정보를 이용해 CICS를 구성할 수 있다. 기존 탄소미터링 시스템은 모바일이 아닌 PC 환경에서 관제 시스템을 제공하지만 본 연구에서는 웹 서버를 추가하여 PC환경에서 통합관제시스템을 제공하는 것뿐만 아니라 모바일에서도 통합관제 할 수 있는 시스템을 제공하도록 구현한다. 그리하여 Linux HA를 적용한 웹 서버를 이용하고 다양한 모바일 기기를 통하여 탄소 관제가 가능한 시스템을 구현한다. Carbon metering integrated control system (Carbon-Integration Metering System, CICS) What is the status of the energy use of IT facilities in real-time has the ability to see and control. CICS based of SmartRack is a constant temperature, humidity sensor based, air conditioners, PDU and other devices are integrated. It is Providing information of Power consumption, carbon emissions, such as. It use configured the CICS. And using the information provided can be constructed of integrated control system. Also, Existing carbon metering system is a Mobile control system, not the PC environment provided. However, in this study, to mobile can be implemented that to provide in the integrated control system by adding Web servers. To safety of web server is applied Linux HA. To deal intelligently in case of emergency. In this paper, Mobile carbon monitoring system implementation using Linux HA clustering on CentOS 5.5 environment.

The authors have tried this pilot study to investigate the differencies by sex of the psychiatric charscteristics of the patients who visited emergency room. The subjects in this study composed of 667 psychiatric patients who visited emergency room of Pilding Hospital and Yongsan Hospital, Chang-Ang University Medical Center from June 1991 to May 1992. Patient records were reviewed for demographic data(age, residence), mode of arrival(time, season, and accompanying person), disposition, manner of discharge and clinical features(causes of visit, symptoms, precipitatinf factors and psychiatric diagnosis) as dependent variables. Data were analyzed by chi-square test using SPSS/PC+. In analysis, there were significant differencies in variables such as accompanying person, disposition, manner of discharge, causes of visit, symptoms, precipitating factors and diagnosis. The summaries of the results were as follows. 1) The most frequent accompanying.persons were their families and others in both male and female group, but the number of patients who visited emergency room by themselves were higher in male group. 2) The rate of admission was higher in male group, on the other hand, the rate of OPD follow up was higher in female group. 3) The rate of discharge against medical advide was higher in female group. 4. Neutotic symptoms were the most prevalent causes of visit in both male and female group, but drug use was more prevalent in male group and acute psychotic symptoms were more prevalent in female group. n 5) Somatic symptoms and depressive symptoms were more prevalent in female grou, on the other land, anxiety symptoms and psychotic symptoms were more prevalent in male group. 6) Economic problems were more prevalent precipitants of psychiatric symptoms in male group, on the other hand, marital problems were more prevalent precipitants of psychiatric symptoms in female group. 7) Anxiety disorder and drug use disorder were more prevalent diagnosis in male group, on the othe hand, somatoform disorder and mood disorder were more prevalent diagnosis in female group. The results will be helpful to the clinicians, who work in the emergency room, in making diagnosis and treatment decesions more accurately.

The author has tired to extract antisocial personlity and attitude variables which can discriminate delinquent adolescents from adolescent students and make the development of delinquency predication scale, thus identifying students who have high delinquent propensity in early stage and providing coping strategies for them. Two thousand one hundred and ninety sevev(2,197) person served for this study comprised of 1,440 adolescent students from eight boy's and girl's junior and senior high schoolsm and 757 adolescent delinquents from four iuvenile correctional institutions in Seoul and the other two countries. Sampling were made through disproportional probability sampling producedure, and questionnaires composed of thirty five items related to the antisocial personality and were supplied. The collected data were processed by CDC-174 computer of the KAIST, and were statistically analysed by t-test and multiple discriminant function analysis with SPSS program. Summary of the major findings were as follows. 1. The total score of the Chung Ang University self-rating Antisocial Personality Scale of the delinquent adolescent(0.359±0.170) was higher than that of the adolescent student(0.250±0.162). This result suggest that the higher antisocial personslity trend correspond with the higher delinquent inclination. 2. The total score of the negative attitude toward the society in the delinquent adolescent(0.099±0.024) was higher than that of the adolescent student(0.092±0.067), and the total score of the negative attitude toward the teacher in the delinquent adolescent(0.094±0.052) was higher than that of the adolescent student(0.089±0.044), but there is no significant difference between the delinquent adolescent and adolescent student to the score of negative attitude toward the elders. These results suggest that the delinquent inclination is higher in the occasion of the distored attitude toward the society and the teacher. 3. In comparison of mean score of discriminant function coefficients between delinquent adolescent and adolescent student throughout the MDFA, the antisocial trend in the delinquent adolescent(0.846) was higher than that of the adolescent student(-0.284). This result suggest that the delinquent adolescent tend to have higher antisocial inclination than that of the adolescent student. 4. The result of multiple discriminant function analysis to know the discrimination ability of the antisocial personality and attitude items to predict the delinquent adolescent from adolescent student show that 35 items of antisocial personality and attitude scale has seventy three percent in its accuracy to discriminate the differences of both groups effectively. this result suggest that the antisocial personality and attitude scale of this study has higher validity to extract delinquent adolescent and little possibility in taking mistake to extract delinquent adolescent. 5. The highest delinquent prediction factor among thirty five antisocial personality and attitude items was negative attitude toward the money-oriented society which has discriminant coefficient more than 0.1 were veral aggressive drive, drunken impulse, lying impulse, critical attitude toward teacher's hypocricy, mistrusting impulse, staying out late impulse, attitude toward social disadvantage, stormy aggressive drive, stealing impulse and slovenly apperance in their orders.
