The purpose of the current study is to examine the structural relationship between communication competence and self-presentation through motivational perspectives. The present study hypothesized structural model to examine the effects of autonomy, relatedness, and life satisfaction along with communication competence on the self-presentation. We investigated how these effects were influenced by differences in the structural relationships of males and females. The data with the sample of 361 college students adequately fit to the hypothesized model. Through latent mean analysis, gender differences of the constructs were examined. The female students appeared to have higher levels of relatedness than the male students. The results showed that autonomy and relatedness are important factors to self-presentation mediating communication competence.

본 연구는 기업의 투자효율성이 투자부동산 비중에 미치는 영향을 살펴보았다. 경영자의 사적이익 추구현상과 대리인비용이 클수록 나타나는 과잉투자성향이 기업의 투자부동산 비중을 증가시키는지 분석하였다. 이를 위해 2007년부터 2018년까지 유가증권시장과 코스닥시장의 5,781개의 기업-연도를 대상으로 분석하였으며 투자효율성은 McNichols and Stubben(2008)의 연구방법론으로 측정하였다. 분석결과는 다음과 같다. 첫째, 투자 비효율성이 커질수록 기업의 투자부동산 비중이 증가하는 것으로 나타났다. 이는 투자 비효율성이 높을수록 나타나는 대리인비용과 경영자의 제국건설성향이 투자부동산 비중과 유의한 관련성을 갖는다는 것을 의미한다. 둘째, 유가증권시장과 코스닥시장으로 구분하여 분석한 결과에서는 코스닥시장에서 유의성을 확인할 수 없었다. 즉, 투자 비효율성이 커질수록 나타나는 투자부동산의 비중은 유가증권시장에서 관찰되었다. 셋째, 투자 비효율성을 과잉투자와 과소투자로 구분하여 분석한 결과에서는 과잉투자성향이 증가할수록 투자부동산의 비중이 증가하였으나 과소투자와는 관련성이 나타나지 않았다. 이상의 연구결과는 그 간의 선행연구에서 주로 투자부동산과 기업 가치의 관련성에 초점을 맞추었던 반면, 대리인비용과 투자부동산 비중 간의 실증적 증거가 부족한 가운데 추가적인 학문적, 실무적 시사점을 갖는다.

The purpose of this study was to determine the possibility of character education in the middle school home economics program: by extracting learning factors that can cultivate gratitude disposition from the eighth grade in the unit of 'clothing life' of middle school HE text, developing five teaching-learning lesson plans and learning materials, and applying them in classrooms to see any changes in gratitude disposition standards before and after its application. Five teaching-learning lesson plans for the cultivation of gratitude disposition were developed, and completed after three experts in home economics verified their validity and revised them. From June 1, 2010 to June 30, 2010, five classes were to 210 grade students at a Gyeongbuk Junior School, and dispositions were investigated before and after the classes. Gratitude disposition standards used GQ-6, like McCullough, and for before-and-after-inspection comparison, t-test and analysis of open-ended questionnaires were carried out. The results proved the instruction effective. Before the class for the cultivation of gratitude disposition, students had a gratitude disposition average of 2.87(out of 5). After the class, the average was 3.35, which shows that students had improved considerably. Also, in analysis of a open-ended questionnaire, it was said that the class had been provided the opportunity to think about the value of nature and neighbors and that the class content reminded them about appreciation. In conclusion, for the character education in other areas of middle school home economics, teaching-learning lesson plans development must be attained to further this character education program.

The advancement of digital technology accelerates intelligence, convergence, and demands better change beyond traditional methods in all aspects of business models and technologies, infrastructure, processes, and platforms. Risk management is becoming more important because of various security risks, depending on the changing business environment and aligned to business goals is emerging from the existing information asset based risk management. For business aligned risk management, it is essential to understand the risk appetite for achieving business goals, which provides a basis for decision-making in subsequent risk management processes. In this paper, we propose a framework for analyzing the risk management framework, pre - existing risk analysis, and protection motivation theory that influences decisions on security risk management. To examine the practical feasibility of the developed risk appetite framework, we reviewed the applicability and significance of the proposed risk appetite framework through an advisory committee composed of security risk management specialists.
