The political influences of general programming channels have grown with the help of the current affairs talk programs for years but also these channels have been criticized as politically biased media. This study investigates the characteristics of the panels who had appeared for 6 months since July of 2017 and examines the relationship between the panels' talk and the position of political parties. The results show that jobs of the casting panels were introduced as neutral ones which are not related to politics. However, after reclassifying them in terms of their political careers, most panels were more likely to be involved in political parties. In addition, they tend to support the positions of the ruling or opposition parties. The more the association with the political party, the stronger the panel's comments. The partisanship of the panels should be clearly presented in the broadcasting programs. It is necessary to distinguish genres of current affair programs by consistent standards to ensure consistency of deliberation. Lastly self-regulation of program producers should be more strengthened.

In this study, we attempt to identify factors that influence the performances of Korean firms regarding global R&D cooperation, and to derive policy implications for performance improvement. The hypothetic influential factors include firms' general characteristics, purposes and types of cooperation, technology, partners and their countries, and government support. We categorize the performances of global R&D cooperation into technological, economic, and strategic performance, and analyze the effects of those factors on each of the performances as well as the overall performance. We use a standard tobit model for the overall performance, while using a multivariate tobit model for the other performances to reflect the possible correlations among them. The survey data was collected from 162 Korean firms that had previously conducted or were currently conducting global R&D cooperation.

Objective : This study aimed to assess the applicability of the Yonsei Lifestyle Profile (YLP), initially developed for adults, for adolescents and verify its reliability and validity. Methods : This study evaluated the reliability and validity of the YLP among 436 middle and high school students in South Korea. The internal consistency of this scale was analyzed using Cronbach's alpha and Spearman-Brown's coefficient. Concurrent validity was assessed using Pearson's correlation coefficient with the Korean Youth Physical Activity Questionnaire, the Korean version of the Children and Adolescents Participation Scale, and the Nutrition Quotient for Adolescents. Results : The overall internal consistency of the YLP items demonstrated high reliability, with a Cronbach's α of .811 and Spearman-Brown's coefficient of .779. Significant positive correlations were observed for physical activity (r=.555, p<.01), activity participation (r=.177, p<.01), and dietary habits (r=.633, p<.05), indicating consistent correlations with the related scales. Conclusion : This study analyzed the YLP targeting adolescents and confirmed its high reliability and significant validity in the areas of physical activity, activity participation, and dietary habits. These findings suggest that the YLP can be utilized as a reliable tool for evaluating healthy lifestyles among adolescents.

최근에 작업현장에서 널리 사용되고 있는 허리보호대는 그 예방적 효과에 대한 확실한 검증이 이루어지지 않고 있다. 작업현장에서의 허리보호대의 예방적 효과에 대한 8편의 생체역학적(biomechanical) 연구들과 6편의 역학적(epidemiological) 연구들 그리고 2편의 종합적 연구들을 비교 정리하였다. 대부분의 생체역학적 연구들은 허리보호대의 기계적 작용과 그에 따른 예방적 효과와의 직접적인 상관관계를 보여주지 못하고 있다. 역학적 연구들은 일관성 없는 결과들을 발표하여 작업현장에서의 허리보호대의 예방적 효과에 대한 연구결과간의 비교를 어렵게 하고 있다. 좀더 확실한 결론을 얻기 위해서 앞으로 작업현장에서의 허리보호대의 예방적 효과에 대한 더 많은 연구가 있어야 할 것이다.

In a group of 353 elementary students, the present study examined the moderation effects of prosocial behaviors and social competence in the relations between overt/relational aggression and peer status (social preference and perceived popularity). The results indicate that both overt aggression and relational aggression lowered social preference regardless of gender. Prosocial behaviors and social competence did not buffer the negative influence of aggression on social preference. Among boys, overt aggression was a significant predictor of increased perceived popularity. Although inconsistent, relational aggression also predicted boys' perceived popularity. However, among girls, relational aggression, not overt aggression, was associated with perceived popularity. The moderation effects of prosocial behaviors and social competence were significant only among boys. In other words, boys' aggression, although it lowers social preference, contributes to their social influence and dominance when it is effectively combined with positive characteristics. It is necessary to develop new intervention strategies which reflect the adaptive function of aggression within peer groups.

Energy is an essential element in economic activity and people's lives, an important resource used by various industries, and the financialization of commodity markets has led to the growing importance of crude oil turning into the same asset as other assets. Accordingly, studies analyzing the correlation between energy prices and investor sentiment explain that investor sentiment affects oil prices through economic factors and speculation. In this study, we wanted to analyze whether the impact of the most representative changes in oil prices affects investor decision making, affecting investor sentiment, and applying wavelet consistency analysis to determine how energy prices relate to investor sentiment. Studies show that policies should be focused on policy and market changes because energy prices differ by time scale and investment sentiment should be more influential in the long term than in the short term.

This paper classifies technical, administrative and physical areas of defects and advices made by an external audit (ISO27001) and internal audit (performed by a security team) in a company which has the management system of information security. With the classified data it finds the correlation between the budget and investment of information security, and analyze the correlation. As a result of the analysis, it has been found that as time goes on there is a consistent correlation between a administrative area and technical area of security. Specially, it has been confirmed that the relation between the scale of the budget which is not executed and the number of the defects and advices made by the audit is in direct proportion. Therefore, in this paper, so as to provide a model that can be used for validating the effectiveness of the protective investment information by statistically calculating the similarity based on the results of correlation analysis. This research is intended to help that a company makes a precise decision when it establishes a policy of information security and systematic methodology of the investment in information security.

본 실험은 청각 사상관련전위(ERP)를 이용하여 다양한 성격 특질 모형들의 생물학적 근거와, 구조의 공통점과 차이점을 명확히 하기 위해서 설계되었다. 48명의 대학생 피험자들에게 4가지 성격 측정 검사(NEO-PI-R, EPQ-R, BIS/BAS 척도, IVE)를 시행하고, 이어 두 종류의 청각 자극 세트(50ms와 300ms)를 이용한 오드볼 과제를 통해 ERP를 측정하였다. 설문지 간의 상관과, 설문지와 ERP 내외생적 구성 요소 간의 상관, 그리고 그 상관의 두피 분포 양상을 통합적으로 고려하여 해석하였다. 각 성격 검사의 외향성 척도에 해당한다 할 수 있는 E, E, BAS-FUN은 양성 모두에서 높은 수준의 설문지 척도 간 정적 상관을 보였으나, 50ms 자극으로 유발된 P3 진폭은 E와 BAS-FUN에 대해서만 유의하게 높은 상관을 나타내었다. 이 결과는 Eysenck의 모델과 일견 일치하는 결과이지만, 그가 개발한 EPQ-R의 외향성 척도(E) 보다는 오히려 다른 척도들이 뇌파에 반영된 성격의 생물학적 기제를 측정하기 위한 적절한 도구일 수도 있음을 시사한다. 신경증적 경향성을 반영하는 N과 N 척도는 50ms 자극에 대한 여성 피험자의 N1, P2 진폭과 유의한 상관을 보였다. 그러나 이론적으로 두 척도에 등가적인 것으로 예상되었던 BIS 척도는 설문지 간 상관이나 ERP 요소와의 상관에서 모두 유의한 결과를 보이지 않았다. Eysenck가 성격의 세 번째 축(차원)으로 제시했던 P(정신병적 경향성) 역시 여성 피험자들에게서 두드러지는 설문지 간 상관을 보였으나, 300ms 자극에 대한 P2 진폭과의 정적인 상관은 양성을 합한 자료에서만 발견되었다. 여성의 상관 분포는 비록 통계적으로 유의한 수준에는 이르지 못하였으나, 양성 자료의 분포와 유사함이 확인되었다. 이 실험의 결과는 P3 진폭과 외향성 간의 부적인 상관 관계를 보고하였던 기존 연구들을 지지한다. 또한 본 실험에서 확인된 Eysenck 모델의 신경증적 경향성이나 정신병적 경향성이 ERP의 비교적 초기에 나타나는 외생적 구성 요소들(N1, P2)과의 상관 양상은, P3 요소에 집중하였던 기존 연구들이 외향성 이외의 차원으로 일관된 결과를 얻어내지 못했던 이유를 설명해줄 수 있을 것이다. 또한 성격 차원과 그것을 지표 하는 ERP 구성 요소 간의 관계를 해석할 때에 성별이나 유발 자극의 속성을 고려해야 함을 보여준다.

This study sought to investigate interrelationships and differences of brachial-ankle pulse wave velocity (baPWV), body composition and cardiovascular variables between genders who have been exercised or not in elderly. One hundred fifty participants were classified four groups. Especially out of variables, in male elderly group who had participated in exercise program the PWV range were significantly correlated with muscle mass (r=0.357, p=0.026), SBP (r=0.468, p=0.003), right baPWV (r=0.406, p=0.010), and left baPWV (r=0.333, p=0.038). In male elderly group who had not participated in exercise program, the PWV range were significantly correlated with heart rate (r=0.395, p=0.014), right baPWV (r=0.598, p=0.000), and left baPWV (r=0.602, p=0.000). In female elderly group who had participated in exercise program, the PWV range were significantly correlated with name of diagnosis (r=0.321, p=0.044), SBP (r=0.399, p=0.011), DBP (r=0.545, p=0.000), right baPWV (r=0.648, p=0.000), and left baPWV (r=0.676, p=0.000). In female elderly group who had not participated in exercise program, the PWV range were significantly correlated with age (r=0.471, p=0.003), right baPWV (r=0.836, p=0.000), and left baPWV (r=0.801, p=0.000). The PWV among four groups were not significant different after experiment. However, there were significant differences in the waist/hip ratio (F=9.197, p=0.000), muscle mass (F=74.295, p=0.000), and %fat (F=35.045, p=0.000) from body composition. And there were significant differences in the SBP (F=3.525, p=0.017) after experiment. In conclusion, these data show that regular exercise is associated with arterial compliance (PWV range, right or left PWV) and differed from genders. In other words, this paper may support the concept that regular exercise program may exert a protective effect on arterial compliance, body composition and cardiovascular systems.
