There have been arguments in Korea that fair value accounting system improves quality of accounting information through the asset revaluation. These arguments are based on the fact that investors prefer fair value to cost value information. Others argue that cost principles may offer more proper information to the investors because financial statements applied the cost principles are more objective and thus more reliable. Prior researches focused mainly on the motives of asset revaluation but I examined the effects of the tangible asset revaluation on the stock prices. The empirical findings indicate that : (1) the gains on the tangible asset revaluation are positively correlated with the stock prices; (2) the net book values applied the cost principles explain stock prices better than the net book values applied fair values. My findings suggest that the gains on the tangible asset revaluation constitute a part of the firms' values but the accounting informations measured fair value are not always useful to the investors in the capital market.

자연재난은 각각의 유형별로 발생 특성이 다양하고, 피해 유형도 상이하기에 재난 발생 시 재난 특성에 따른 최적 자원의 비축 및 동원이 필요하다. 하지만, 재난관리자원은 종류가 다양하고 요구 비축량이 많으며, 재난유형별로 발생특성이 다양하고 피해유형도 상이하기 때문에 모든 자원을 비축하고 활용하기에는 어려움이 따른다. 따라서 재난특성에 맞는 필요 자원의 비축을 통한 효율적인 재난관리자원 운영 및 관리체계 마련이 필요하다. 특히, 침수관련 재난(호우, 태풍, 풍랑)의 경우 과거 20년(2001년~2020년)동안 발생 건수는 282건으로 같은 기간 발생한 413건의 자연재난 중 68%를 차지할 만큼 침수 대응에 따른 필요 자원의 분석이 필요하지만, 관련 자원의 운영현황 및 발생한 문제점에 대한 분석은 미흡한 실정이다. 이에 본 연구에서는 과거 20년(2001년~2020년)동안 발생한 침수관련 재난(호우, 태풍, 풍랑)발생 시 동원된 재난관리자원 사례를 분석하였다. 재해연보, 관련 백서 및 보고서 등의 수집 및 분석을 통해 침수 발생 시 동원된 장비, 자재를 분석하였으며, 자원동원 시 발생하는 문제점을 자원비축, 자원능력, 자원활용, 대응시간으로 구분할 수 있었다. 본 연구는 과거 발생한 침수관련 재난에 대하여 재난관리자원의 동원 사례와 시사점 및 문제점을 도출한 점에서 그 의미가 있으며, 향후 침수 관련 재난 발생 시 자원의 효율적인 비축 및 관리, 동원 및 응원 등 효율적 운영방안 수립에 활용할 수 있을 것으로 기대된다.

The element that effects on a level of current passive leisure activity type, it resulted as two variables of internal barriers, three variables of external barriers, the explanation ability was analysed as to 48%. it resulted as two variables of internal barriers, five variables of external barriers in active leisure activity, five variables of external barriers, the explanation ability was analysed as to 29%. Therefore, based on various constraints of disabled people in Korea, a plan should be prepared to encourage participation of leisure activity, and systematic review and detailed study on two academic subjects related to leisure and disability should be done.

This study is intended to study the usage of augmented reality(AR) in the marketing field by classifying them into display and content types and analyzing the typical cases and characteristics. The market for AR has been on the increase and has been a big influence in the marketing field, resulting in the generalization of the term "AR marketing." By analyzing the marketing cases which use AR technology and organizing the frequency of use and characteristics, it is expected to contribute as a basic material for future studies on AR marketing. In this study, AR marketing cases are classified into different categories including display and contents. First, AR display category includes personal computers, mobile, public display, and projection display. AR contents category includes informative content, game contents, virtual experience, and visual effect. While investigating, it was found that the most used type of AR display was mobile, which has the advantage of not being limited by time and place and is also capable of one-on-one marketing with customers.

The purpose of the study is to verify what cognitive variables have significant effect on proportional problem solving. For this aim, the study classified proportional problem into well-structured, moderately-structured, ill-structured problem by the level of structuredness, then classified the cognitive variables as well into factual algorithm knowledge, conceptual knowledge, knowledge of problem type, quantity change recognition and meta-cognition(meta-regulation and meta-knowledge). Then, it verified what cognitive variables have significant effects on 6th graders' proportional problem solving abilities through multiple regression analysis technique. As a result of the analysis, different cognitive variables effect on solving proportional problem classified by the level of structuredness. Through the results, the study suggest how to teach and assess proportional reasoning and problem solving in elementary mathematics class.

The purpose of this study was to investigate the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles. The subjects were 399 middle school students and 366 high school students in four middle schools and two high schools in metropolitan and small towns for one month from July 1, 2017. Data were analyzed through descriptive statistics, correlation analysis. Multiple regression was used to see how parent-adolescent communication styles, self esteem, and depression affect the career decision-making style. As a result, first, open communication with mothers has a statistically significant effect on the rational career decision-making style and open communication with fathers has a statistically significant effect on the intuitive career decision-making style of adolescents. Second, self-esteem of adolescents showed a positive correlation with rational career decision-making style and negative correlation with dependent career decision-making style, and depression showed a positive correlation with dependent career decision-making style. The results may help to understand the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles and be used for counseling intervention.
