Real-time energy monitoring systems is a demand-response system which is reported to be effective in saving energy up to 12%. Real-time energy monitoring system is commonly composed of smart-plugs which sense how much electrical power is consumed and IHD(In-Home Display device) which displays power consumption patterns. Even though the monitoring system is effective, users should themselves match which smart plus is connected to which appliance. In order to make the matching work to be automatic, the monitoring system need to have appliance identification algorithm, and some works have made under the name of NILM(Non-Intrusive Load Monitoring). This paper proposed an algorithm which utilizes multiple classifiers to improve accuracy of appliance identification. The algorithm proposes to understand each classifiers performance, that is, when a classifier make a result how much the result is reliable, and utilize it in choosing the final result among result candidates from many classifiers. By using the proposed algorithm this paper make 4.5% of improved accuracy with respect to using single best classifier, and 2.9% of improved accuracy with respect to other method using multiple classifiers, so called CDM(Commitee Decision Mechanism) method.

본 연구는 전문직 은퇴자와 은퇴예정 남성으로 구분하여 자원봉사 몰입과 심리적 안녕감 간의 관계에서 사회자원, 자원봉사활동, 자원봉사활동 만족도 등의 매개효과를 검증 함으로서 그들의 심리적 안녕감을 높이기 위한 기초자료를 제공하는데 목적이 있다. 이를 위해 서울, 경기도에 거주하는 55세~69세의 자원봉사를 수행하고 있는 전문직 은퇴(예정)자 284명을 대상으로 설문지 자료를 수집하고, SPSS를 활용하여 기술통계 및 회귀분석을 실시하였다. 연구 결과, 첫째, 자원봉사 몰입과 심리적 안녕감 간의 관계에서 전문직 은퇴자는 가족, 친구, 이웃 간 접촉과 모임 참석과 같은 공식적/비공식적·사회적 상호작용 등의 사회자원의 역할이 개인적 성장과 삶의 목적에, 은퇴예정자는 긍정적 대인관계가 매우 중요하다는 것을 알 수 있었다. 둘째, 자원봉사 몰입과 심리적 안녕감 간의 관계에서 자원봉사활동기간은 개인적 성장과 삶의 목적에, 은퇴예정자는 삶의 목적을 부적(-)으로 매개하는 것으로 검증되었다. 또한 자원봉사활동 만족도는 사회자원과 자원봉사활동기간을 다단계 매개하는 또 하나의 매개 경로임을 확인하였다. 이와 같은 연구 결과를 토대로 지역사회 내에 있는 공식/비공식 사회자원을 최대한 활용하고 그들을 대상으로 자원봉사 활동을 유지시킬 수 있는 서비스의 지원을 통해 그들의 심리적 안녕감을 향상시킬 수 있는 프로그램을 개발하는 것이 필요하다. The objective of this study was to verify the mediating effect of social resources and volunteer activity on the relationship between volunteer work commitment and psychological well-being of male volunteer groups divided into professional retirees and prospective retirees. To achieve the goal, a survey research was performed for men of 284 between the ages of 55 ~ 59 in Seoul, Kyunggi distinct. SPSS were applied in technical statistics, and the Regression Analysis was performed. The results of the study are: Firstly, among the professional retirees, with respect to volunteer work commitment and psychological well-being, the role of social resources, such as their contacts between family, friends and their neighbors as well as their attendance at formal and informal gatherings, and the roles of their social functions are proved to be vital in personal growth and their purpose of life. Secondly, with respect to the volunteer commitment and psychological well-being, the period of volunteer works proved to be vital to the purpose of their living, whereas the prospective retirees regard that as a secondary factor for their purpose of living. This study suggests that developing support systems for services to maintain the levels of volunteer works, as well as developing programs to decrease the volunteer work`s burnout are necessary.

청소년 성폭력 예방을 위한 사회복지적 접근 - 가해자와 피해자를 중심으로 -

박용순(Yong Soon Park) 한국청소년학회 2000 청소년학연구 Vol.7 No.2

본 연구는 청소년 성폭력의 희생자인 가해자·피해자에 대한 실태와 문제점을 분석하여 이들의 성폭력 예방을 위한 사회복지적 대응방안을 모색하는데 목적이 있다. 성폭력 범죄는 청소년 문제의 핵심적인 문제로서 이를 미리 예견하고 성폭력 가해자와 피해자 양자를 위한 복합적인 접근방법이 필요하다. 왜냐 하면 청소년 성폭력의 가해자나 피해자 모두가 희생자이기 때문이며, 성폭력을 단순한 성적인 범죄행위가 아니라 성장하는 청소년들의 육체적, 정신적, 인권적인 폭력행위라는 점에 있다. 따라서 본 연구는 사회복지적 차원의 대응방안으로서 두 가지 접근방법을 제시하였다. 첫째는 정책적인 접근방법으로서 (1) 가해자를 위한 개입방안과 (2) 피해자를 위한 개입방안을 제시하였다. 둘째는 실천적인 접근방법으로서 (1) 가해자를 위한 개입방안과 (2) 피해자를 위한 개입방안을 제시하였다. 그리고 청소년 성폭력 예방을 위한 새로운 방향으로서 (1) 전문적 지원체계, (2) 법적인 지원체계, (3) 가정의 지원체계 , (4) 학교의 지원체계, (5) 언론의 지원체계 등을 제언하여 청소년 성폭력 범죄를 미리 예견하고 가해자·피해자 양자를 도우며 성폭력을 근절하는 사회를 형성하는데 의의를 두고 연구하였다. This study aims to present the countermeasures of social welfare for the prevention of the juvenile sex assault, analysing the actual condition and problem of both the rapist and the victim. The juvenile sex assault as the core problem of the juvenile delinquency needs being approached through the complex measure for the both by being foreseen. The reason of it is that both of them are also the sufferers of the crime and that such crime is not that of simple sexuality but that of the physical, spiritual and characteristic to the growing youths. Accordingly, two kinds of approaches are presented as the dimension of the social welfare. The first are the intervention approach for the rapist and that for the victim as a policy one. The second as a practical one are the same as the first. As a new approach for the prevention of the juvenile sex assault, a legal support system, school`s support one and the masscom`s support one are suggested. The import of this study is to build the assault-free society by foreseeing such assault and helping both concerned.

박용순 ( Yong Soon Park ),문일봉 ( Il Bong Moon ),동경래 ( Kyung Rae Dong ),여화연 ( Hwa Yeon Yeo ) 조선대학교 공학기술연구원 2014 공학기술논문지 Vol.7 No.1

This study is intended to implement images using fast spin echo fat saturation and IDEAL techniques as the fat suppression of reducing fat signal phase artifact caused by chemical shift phenomena on the boundary interface between water and fat, and the consecutive qualitative analysis was carried out in order to compare the availabilities of those imaging techniques. The comparison was conducted by applying the fast spin echo (FSE) T2 weighted pulse sequence and IDEAL techniques to the test. 1.5 Tesla MR scanner (Signa HDxt, GE, USA) and 16 channel CTL coil were employed in the test as the MR imaging devices. For image point, FSE technique was applied to gain images as follows: TR as 2617 / 4250 ms, TE as 85 / 110 ms, Matrix as 320 × 192 / 320 × 224, ETL as 22 / 24, FOV as 330 ㎜, and slice thickness as 40 mm. For those by IDEAL technique, the image implantation was carried out under the following conditions: TR as 4250 ms, TE as 110 ms, FOV as 330 ㎜, Slice thickness as 40, Matrix as 320 × 224, ETL as 24, Band width as 62.50 ㎐, and NEX as 2. As the qualitative analysis method, the signal to noise ratio and the contrast to noise ratio were obtained from the areas of interest in each group, and the values among each group were comparatively analyzed to determine the higher availabilities between the fast spin echo fat saturation and IDEAL-FSE techniques for the fat suppression. As results of imaging, the SNR values of fat at the given points for FSE technique were 0.933, 0.926, 0.953, and 0.956, respectively, while that for IDEAL technique was 0.97. The SNR values for water for FSE technique were 0.316, 0.233, 0.296, and 0.196, respectively while that for IDEALtechnique was 0.44. The required time for FSE technique were 1 minutes 40 seconds, 2 minutes 54 seconds, 1 minute 29 seconds, and two minutes 54 seconds while that for IDEAL technique was four minutes 28 seconds. When FSE imaging and IDEAL techniques that used the identical image points with IDEAL technique were compared among other FSE techniques, SNR of IDEAL technique was 1.017 times of that in FSE, and the time requirement was 3.011 times larger. Though IDEAL technique required 3.011 times longer time than that of FSE T2 technique, but SNR was just 1.017 time higher while CNR became 0.896 times lower. Implication by the study results may include that IDEAL technique may be used to obtain images of uniform fat suppression with excellent SNR, but FSE T2 needs to be used to promote the convenience of patients based on relatively short test time.

본 연구는 사회교환이론의 호혜성과 공정성, 심리적 계약을 적용하여 카지노 산업의 긍ㆍ부정적 효과에 대해서 살펴보고 있는데, 특히 본 연구에서는 카지노 산업의 확대와 관련하여 국가와 국민이 바람직한 사회적 관계를 형성하기 위한 역할과 노력에 대해서 살펴보고 있다. 먼저, 호혜성 측면에서는 국가와 국민간의 상호호혜의 관점에서 경제적 측면과 사회문화적 측면을 동시에 고려해야 한다. 둘째 공정성 측면에서는 국내 외국인 전용 카지노에 대한 공정한 재평가와 재배치를 통해 지역사회와 국가가 상생할 수 있는 협력방안이 필요하다. 셋째, 심리적 계약측면에서는 국가는 카지노 산업의 적절한 지역적 안배를 통해 지역사회 구성원과 건전한 상호교환관계를 형성해야 한다. 본 연구를 통해 확인할 수 있는 것은 국가의 일방통행식의 카지노 산업 확대정책은 국민들의 사회적 공감대가 형성되어 있지 않는 순간 사회교환관계는 더 이상 유지될 수 없다는 것이다. 특히, 카지노 산업은 현재에도 국민들에게 사행산업이라는 부정적인 인식이 지배적인 상황에서 카지노 산업을 정책적으로 육성하기 위해서는 국가와 국민 모두에게 경제적, 사회ㆍ문화적으로 이익을 줄 수 있도록 각자에게 주어진 사회적 책임을 통한 적극적인 사회교환 관계의 유지가 필요하다. 본 연구는 카지노 산업 육성과 관련하여 국가와 국민간의 관계를 사회교환이론을 통해 이론적으로 접근하고 있는 데에 의의가 있으며, 향후 카지노 산업의 바람직한 사회적 관계형성에 기여할 수 있을 것이다. This study explored the positive and negative effect of casino industry to applies the reciprocity, fairness, psychological contract of social exchange theory. Especially, with regard to the expansion of the casino industry, it examines the role and effort to form a desirable social relationship between the state and the people. The development of casino industry, this study approached from three aspects of social exchange theory. First, as a mutual reciprocity aspect, it should consider the economic and socio-cultural characteristics at the same time. Second, in fairness aspect, the nation and regional community cooperation plan to gain a mutual benefits through fair reassessment and re-deployment is required for foreigner exclusive casino. Third, as psychological contract aspect, States should form a sound exchange relationship with community members through an appropriate regional arrangement in the casino industry. The major contribution of this study is confirming that it does not form a social consensus between the state and the people, social exchange relationships could not be established. therefore, in order to foster the casino industry policy should be able to benefit from the economic, social and cultural both countries and peoples. In addition, it is necessary to maintain an active social exchange relationships through social responsibility given to the country and the people, and it will be able to provide very useful implication for the development of casino industry in the future.
