This paper investigates different types of leadership found in foreign coaches in charge of the Korean national soccer team. To that end, news articles published during the tenure of those coaches were crawled for analysis. The analysis highlighted the following results. First, successful sports leaders showed their own specific types of leadership. Second, failed sports leaders showed specific types of leadership. The findings have the following implications. The leadership established based on the analysis results have practical implications in that they suggest the types of effectiveness leadership that are required of sports leaders in managing and leading athletes whilst generating tangible results and performance.

Relation extraction is an important information extraction technique that can be widely used in areas such as question-answering and knowledge population. Previous studies on relation extraction have been based on supervised machine learning models that need a large amount of training data manually annotated with relation categories. Recently, to reduce the manual annotation efforts for constructing training data, distant supervision methods have been proposed. However, these methods suffer from a drawback: it is difficult to use these methods for collecting negative training data that are necessary for resolving classification problems. To overcome this drawback, we propose a one-class classification model that can be trained without using negative data. The proposed model determines whether an input data item is included in an inner category by using a similarity measure based on lexical information and syntactic patterns in a vector space. In the experiments conducted in this study, the proposed model showed higher performance (an F1-score of 0.6509 and an accuracy of 0.6833) than a representative one-class classification model, one-class SVM(Support Vector Machine).

The information on the land cover along stream corridor is important for stream restoration and maintenance activities. This study aims to review the different classification methods for mapping the status of stream corridors in Seom River using airborne RGB and CIR digital ortho imagery with a ground pixel resolution of 0.2m. The maximum likelihood classification, minimum distance classification, parallelepiped classification, mahalanobis distance classification algorithms were performed with regard to the improvement methods, the skewed data for training classifiers and filtering technique. From these results follows that, in aerial image classification, Maximum likelihood classification gave results the highest classification accuracy and the CIR image showed comparatively high precision.

One of the most popular keywords in 21th century is "Information Society". Information Society improves the overall quality of human life, but increases the negative aspects such as internet addiction and digital divide. The purpose of this study is to understand the vicious cycle between socio-economic disparities and digital divide. This study analyzed the effects of poverty on school maladjustment and academic achievement and mediation effects by using parental monitoring and internet use types as mediators. Data were obtained from the Korea Youth Panel Survey(KYPS). Structural equation modeling was employed for statistical analyses. The result showed that poverty reduced parental monitoring and information-oriented type of internet use. Youth who used less information-oriented type showed more school maladjustment and less academic achievement. However, the relationship between poverty and entertainment-oriented type was non-significant. Thus, parental monitoring and the internet use types were one of the main pathways which can affect school maladjustment and academic achievement among youth in poverty. There was the possible vicious cycle between poverty and digital divide. Based on this study, we strongly suggest improvement of the media competence to solve the problem of digital divide among youth in poverty.

The purpose of this study is to explore the Iranian Woman Film Director Samira Makhmalbaf and her cinema world. Samira represents Iranian Islamic social problem base on her woman identity, and She is a symbolic director who is working Iranian new wave at the 21th. She has directed five movies as (1998), (2000), (2002), (2003), (2008). For this study, explore traits of esthetics, subject and context meaning by analyzing representative three movies. Lastly examines significance of his movies in Iranian film history. In terms of esthetics, she tends to combinate between metaphor and reality, And, In thematic consciousness, consistently describes Islamic women's lives and liberty, anti-war and peace, sympathy for the under-privileged, etc. She inherits the tradition of Iranian third wave 'Children Cinema', and simultaneously tries to overcome Iranian art film tradition. Director Samira Makhmalbaf is a symbol of progress and change in Iranian film history, and is opening the new future of Iranian film.

This study investigated the mediating role that subordinates' job satisfaction might play in influencing the relationships between abusive supervision and subordinates' organizational identification and workplace deviance behavior(WDB-O). With data gathered from employees(N=281) representing a wide array of organizations, structural equation modeling was used to test hypotheses. The results showed that abusive supervision is negatively related to job satisfaction and consequently organizational identification, positively associated with organizational deviance behavior through job satisfaction indirectly and has a direct effect on WDB-O.

This paper is a study on the elected korean leading actors & directors who have stable mobility power for audience and social networking. We elected 153 most reliable Korea actors and directors of stardom" (50 directors, 103 actors); they have to put on the name in the 20 high ranks, and more than twice from the total amount of Korean audience about showing 700 movies by 1998-2007. And then we analyze out 'who might be centre in social networking and social networking between actor and director," through 'Centrality Analysis' using the "UCINET" social networking analysis program Finally, we know 'Kim sang-jin director' is 'key men' and 'star' who reduced uncertainty definitely: For a long time, he combines most stable audience power with broad network successfully.

Most previous studies of software fault prediction model which determines the fault-proneness of input modules have focused on supervised learning model using training data set. However, Unsupervised learning model is needed in case supervised learning model cannot be applied: either past training data set is not present or even though there exists data set, current project type is changed. Building an unsupervised learning model is extremely difficult that is why only a few studies exist. In this paper, we build unsupervised models using representative clustering algorithms, EM and DBSCAN, that have not been used in prior studies and compare these models with the previous model using K-means algorithm. The results of our study show that the EM model performs slightly better than the K-means model in terms of error rate and these two models significantly outperform the DBSCAN model.

This study attempted to verify the structural model of the influence of parental intimacy, parental supervision, peer pressure, and TV alcohol advertising on drinking behavior for adolescents. It was conducted through a self-written questionnaire from May 1 to 28, 2019, targeting 602 students in grades 1 to 3 of 8 middle schools in G city. Results First, The direct effect on drinking behavior was in the order of peer pressure and TV alcohol advertisement, and they explained the degree of drinking behavior by 14.4%. second, Parental intimacy has an indirect effect on peer pressure and drinking behavior through TV alcohol advertising. Parental supervision has an indirect effect on drinking alcohol through TV alcohol advertisements. In multiple groups, there is a difference between the groups in the parental supervision and peer pressure, and the parental supervision and the channel coefficient of TV alcohol advertisement. In order to reduce drinking behavior, a realistic light that can cope with peer pressure is needed.

보험업계는 그 동안 취약한 여건 및 보험의 공공성으로 인하여 정부의 엄격한 감독과 규제하에서 성장하여 왔다고 하여도 과언이 아니다. 이러한 보험업계가 2000년 부가보험료 자율화, 2002년 순보험료 자율화를 통하여 이제 막 보험료에 대한 본격적 경쟁을 시작하고 있다. 그 만큼 경쟁에 대한 심리적 기반 형성이 더디다는 것이다. 따라서 이러한 보험업계로 하여금 본격적인 경쟁을 유도하기 위하여서는 다양한 약관의 개발을 촉진시키고 보험료 인상이나 인하, 부가서비스를 비롯한 새로운 사업추진에 있어 사실상의 행정지도에 속하는 신고나 협의 등의 절차를 대폭 줄이는 등 감독당국에서 스스로의 장애물을 제거해 주는 노력이 필요할 것이다.
