Due to the increase in the demand for anomaly detection according to the ageing of power generation facilities, the need for developing an anomaly detection method that can provide high-reliability turbine blade anomaly detection performance has been continuously raised. Additionally, the false detection results caused by a human error accelerates the increase of the need. In this paper, we propose an anomaly detection technique for turbine blades in power plants using deep neural networks. Experimental results prove that the proposed technique achieves stable anomaly detection performance while minimizing human factor intervention.

Purpose : This study was conducted to survey the preliminary data on risk behaviors and to identify the factors that prevent risk-behaviors in late adolescence. Methods : Freshmen(n=1,297) beginning the first semester in Korea University, Seoul, Korea completed self-administered risk behavior questionnaires, comprising 5 domains : demographics, smoking, drinking, drug abuse and sexual behavior. Results : The rate of smoking experience was higher in people having friends who smoke and the predictors of transition to current smoking were male gender, urban residence, friends' smoking, and nicotine dependence. The rate of high risk drinking was higher among students who are male and who had experience of heavy episodic drinking. The study group showed a low prevalence of narcotic users, but two-thirds of students could get medicine easily without prescriptions. The prevalence of sexual experience was 6.5 percent, and the sexual education was not a predictor of contraceptive behavior. The prevalence of homosexuality was 1.6 percent, and the rate of mostly heterosexuality was higher in female students. Conclusion : The main targets of youth health education should be campaigns aimed at atcessation of reinforcing risk behaviors and the development of a surveillance system for the prevention of chronic disease. These results can be used to find risk factors of health-risk behaviors among late adolescents.

Clustering is to divide given data and automatically find out the hidden meanings in the data. It analyzes data, which are difficult for people to check in detail, and then, makes several clusters consisting of data with similar characteristics. On-Line Document Clustering System, which makes a group of similar documents by use of results of the search engine, is aimed to increase the convenience of information retrieval area. Document clustering is automatically done without human interference, and the number of clusters, which affect the result of clustering, should be decided automatically too. Also, the one of the characteristics of an on-line system is guarantying fast response time. This paper proposed a method of determining the number of clusters automatically by geometrical information. The proposed method composed of two stages. In the first stage, centers of clusters are projected on the low-dimensional plane, and in the second stage, clusters are combined by use of distance of centers of clusters in the low-dimensional plane. As a result of experimenting this method with real data, it was found that clustering performance became better and the response time is suitable to on-line circumstance.

An abnormal object refers to a person, an object, or a mechanical device that performs abnormal and unusual behavior and needs observation or supervision. In order to detect this through artificial intelligence algorithm without continuous human intervention, a method of observing the specificity of temporal features using optical flow technique is widely used. In this study, an abnormal situation is identified by learning an algorithm that translates an input image frame to an optical flow image using a Generative Adversarial Network (GAN). In particular, we propose a technique that improves the pre-processing process to exclude unnecessary outliers and the post-processing process to increase the accuracy of identification in the test dataset after learning to improve the performance of the model's abnormal behavior identification. UCSD Pedestrian and UMN Unusual Crowd Activity were used as training datasets to detect abnormal behavior. For the proposed method, the frame-level AUC 0.9450 and EER 0.1317 were shown in the UCSD Ped2 dataset, which shows performance improvement compared to the models in the previous studies.

Aggressive behavior triggered by the tendency to become angry is generating various social problems. To combat these various social issues, it is important to recognize the role that empathy plays in preventing those with trait-anger from becoming aggressive. More specifically, the hypothesis that empathic concern and perspective taking would mitigate the association between trait-anger and aggression was examined through this study. 329 college students participated in a survey containing questions related to trait-anger, aggression, empathic concern and perspective taking. The results showed that empathic concern moderated the association between trait-anger and aggression, whereas perspective taking did not. That is, those who are emotionally empathetic do not act aggressively easily even if their trait-anger is high; while those who are cognitively empathetic struggle to reduce the likelihood of their trait-anger leading to aggressive behavior. The result of this study indicates that emotional empathy was more useful than cognitive empathy in preventing those with trait-anger leading to aggressive behaviors. The implications, limitations and future directions of this study were also considered and presented as well.

Many researches have argued the most important dimension of perception or evaluation of person is morality and competence in Korean culture. This study was to investigate the cultural characteristics of the criteria of personhood. Two studies were conducted to investigate the criteria used to evaluate person by qualitative approach and the differences of evaluation of wrongdoer who violates interpersonal norm or individual autonomy by experimental method. In addition, anger as emotional response to wrongdoer is conceptualized in terms of moral and self-conscious emotion. Expression of anger is less an outpouring of emotion and more a culturally regulated and normative mode of managing and putting into practice our society's system of rights and obligations - its moral code. According to results of qualitative data by interview and focus group interview, the most important criteria used to evaluate personhood was interpersonal concern, esp, expectation and norm. The results of experiment revealed that violation of interpersonal norm domain evoked angrier towards violator than autonomy domain. The subjects ascribed more blame and responsibility to interpersonal norm violator than autonomy keeper. Also function of behavior inhibition of anger was higher in interpersonal norm domain than autonomy domain.

Purpose: This study aimed to investigate the perception and emotional experiences in rare and intractable diseases for caregivers of pediatric patients with mitochondrial diseases in order to provide therapeutic interventions for patients, caregivers, and families. Methods: A total of 83 caregivers of pediatric patients with mitochondrial diseases were recruited from the pediatric mitochondrial disease clinics of the Gangnam Severance Hospital in South Korea. Participants completed the survey about their perception of mitochondrial disease and emotional experiences after the diagnosis, and these clinical data were analyzed accordingly. Results: Surveys from a total of 83 caregivers of patients were analyzed, and the patients' age ranged from 6 to 12 years (33%), followed by ages 1 to 6 years (30%). Children with mitochondrial diseases were between 0 and 0.5 years of age at the time of first symptom onset (43%), and the duration of illness lasted more than 10 years in most cases (42%). Prior to diagnosis of mitochondrial diseases, the amount of awareness the caregivers had was 'Not at all' for both rare and intractable diseases and mitochondrial diseases in 44 cases and 68 cases, respectively. For the caregivers' emotional experiences, the most common initial responses were 'Discouraged/despair', 'Helpless/lethargic', and 'Disconcerted'. 'Anxious', 'Committed to treatment', and 'Responsibility as family members' were the most common emotional responses from the caregivers, followed by 'Disconcerted' and 'Helpless/lethargic'. Conclusion: It is important to consider the level of perception and emotional experiences of caregivers and patients with rare and intractable mitochondrial diseases for planning treatment programs.

The purpose of this article is to explore French 'minima sociaux', focusing its scheme, benefit determination rule and its level appreciation. First, on the its structure domain, French 'minima sociaux' presents the plural system in which there is eight categorical benefits and one general benefit. Il is the representation of the intention to guarantee minimum income for the dead zone people out of the social insurance application and also a historical product in different period, by different logic of benefits implementation. Second, comparing nine benefits based on the benefit determination rule, level of benefits for the poor without work ability is higher than one for the poor with work ability. Il represents one polarized perception toward for the poor according to have or not its work ability. Third, comparing level of 'minima sociaux' with relative poverty line, the level of the most 'minima sociaux' is placed under the poverty line. Nevertheless, it must not forget that 'minima sociaux' plays its role as the fundamental alternative for poverty alleviation, but not the only alternative. Fourth and finally, comparing with minimum income guarantee(SMIC in french), level of RMI benefit is estimated merely on the 50% of SMIC. We can consider that it is the result of the interaction of the complex factors, as the limited role of the state toward the minimum income guarantee for the RMI beneficiary and the intervention the logic of status instead of the logic of need, etc..

This study aimed to present a comprehensive case management model which might be helpful for social workers in community social welfare agencies who works with North Korean refugees for their psychosocial adjustment in South Korea. After being constructed, the model was put into practice upon North Korean refugees. This article described the whole process of model construction and its application. Detail steps taken in this research include: (a) The researcher had 20 unstructured individual interviews with 11 North Korean refugees in order to identify psychosocial problems that need social workers' intervention; (b) Based upon the problems identified through interviews and previous literature review, program components were identified and sorted out into two phases, one of which is therapeutic phase, the other is case management phase; (c) By interlocking the two phases, the researcher proposed a comprehensive case management model whereby North Korean refugees can get psychosocial services as well as linkage services in an interactive fashion; (d) The utility of the proposed model was examined by using a couple of North Korean refugees who initially showed complicated psycho-social-economic problems. The therapeutic phase employed a cognitive-behavioral approach. The case management phase consists of: assessment and diagnosis; service planning and resource identification; linking of clients to needed services; monitoring of service delivery; and evaluation. Although the program could not go through with because of the limited contacts with North Korean refugees for security reasons, the program was turned out to be very useful in helping North Korean refugees' settling-down in South Korea. Implications for the application of the proposed model was discussed along with limitations of this study.
