This study clarified the big ideas related to teaching addition and subtraction of fractions with different denominators based on quantitative reasoning with unit and recursive partitioning. An analysis of this study urged us to re-consider the content related to the addition and subtraction of fraction. As such, this study analyzed textbooks and teachers' manuals developed from the fourth national mathematics curriculum to the most recent 2009 curriculum. In addition and subtraction of fractions with different denominators, it must be emphasized the followings: three-levels unit structure, fixed whole unit, necessity of common measure and recursive partitioning. An analysis of this study showed that textbooks and teachers' manuals dealt with the fact of maintaining a fixed whole unit only as being implicit. The textbooks described the reason why we need to create a common denominator in connection with the addition of similar fractions. The textbooks displayed a common denominator numerically rather than using a recursive partitioning method. Given this, it is difficult for students to connect the models and algorithms. Building on these results, this study is expected to suggest specific implications which may be taken into account in developing new instructional materials in process.

This study has examined genre tastes of Hollywood movies in Korea. A concept of cultural discount suggests that Hollywood film in foreign countries would be received differently according to its specific attributes. Following the suggestion of cultural discount, this study examines how local reception of Hollywood movies is different in Korea, focusing on film genre, production budget, and U.S. box office. The results show that genres are useful variables for such analysis, indicating that certain film genres are indeed suffering from relatively high cultural discount at the level of Hollywood movie import/distribution. Comedy, specifically, constitutes the crucial particularistic movie genre. However, this study does not find out any significant effect of movie genres on the box office in Korea, controlling the effect of U.S. box office and production budget. As Hollywood studios have recently produced multi-genre movies rather than genre-specific movies to induce a variety of audience who have different movie tastes, the influences of cultural discount disappeared among imported Hollywood movies in Korea. This study also reveals that Hollywood movies of high production budget and of successful U.S. box office are more preferred in Korea.

We can anticipate that animations will form one of the axes and lead popular culture in our future visual age. Recently, research has been actively conducted, but it mainly focuses on their value in culture industry or technologies and methods of producing animations. Of course, research that deals with animation characters has constantly come out. This study focuses on the 'formative elements' of 3D animation characters and attempts differentiation from other research by inducing new logic theoretically. Being freed from the research on characters that has been merely focused on theoretical grounds, this study intends to figure out how audience that is consumers who actually get to watch and feel animations recognizes them and find out related problems and also solutions for them. In particular, this study intends to examine the formative characteristics of 3D animation characters with the characters appearing in , one of the animations that have achieved artistic value as well as commercial success. And for that, the study conducted not only literature review but various surveys and Delphi method as well. Also, the researcher devised an analysis frame to evaluate the formative elements through in-depth discussion with experts. And with this, the study created the forms such as the Elements of Form, Formation Methods of Form and Visual Recognition Elements of Form, examined how audience recognized 3D characters. The process of recognizing an image is influenced by socio-cultural environment or sex, age, and the level of knowledge differently. This was meant to investigate current visual culture and the public's perspective through characters in that represent the visual mode.

The purpose of this study is to examine the effects of corporate social responsibility on organizational identification and customer orientation by flight attendants. In this study, 2 hypotheses based on literature reviews were employed. Questionnaire was also developed based on previous studies. A convenience sample of 217 flight attendants was surveyed and 203 usable questionnaires were analyzed. Corporate social responsibility was divided into economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility by the literature review. Confirmatory factor analysis were conducted to validate the measured variables. Then the data and hypotheses were examined using structural equation modeling (SEM) by AMOS. The results are as follows. Firstly, 'economic responsibility' and 'philanthropic responsibility' have positive effect on organizational identification while 'legal responsibility' and 'ethical responsibility' have no effect on 'organizational identification'. As for the degree of influence, 'philanthropic responsibility' has a greater impact than 'economic responsibility'. Airlines should focus on the responsibility to the community as well as social contribution. Secondly, 'organizational identification' has positive effect on customer orientation. The contribution and limitations of this research were discussed and the future possible researches were mentioned.

Many adolescents in high schools are experiencing school maladjustment by academic stress under the reality of higher-education-oriented schooling. A review of studies of academic stress and school adjustment reveals that ego-optimism is predicted as one of the moderating variables to help adolescents lessen academic stress and increase their school adjustment. The main purpose of this study was to verify the moderating effects of ego-resilience on the relationship between academic stress and school adjustment of adolescents. For this, 496 high school students of tenth and eleventh grade were respectively collected through cluster sampling to be surveyed, and then correlation analysis and moderated regression analysis were conducted. The major findings were as follows. First, there was a negative relationship between academic stress and school adjustment and between academic stress and ego-resilience, but a positive relationship between school adjustment and ego-resilience. Second, the moderating effects of ego-resilience on the relationship between academic stress and school adjustment were not found, although optimism, one of ego-resilience's sub-factors, had a significant moderating effect on them, implying that adolescents' optimism should be enhanced to lessen academic stress and ensure they have a successful school life. The study concludes that optimism is a protective factor for school adjustment caused academic stress and thus schools need to make active efforts to enhance their students' optimism.

Ecotourism is an alternative tourism which can be defined as responsible tourism in natural areas. This study deals with changing the tourists' environmental attitudes of ecotourism activities based on the elaboration likelihood model(ELM). The surveys were conducted based on the same participants to clearly measure the differences of environmental attitudes between pre and post-participation ecotourism activities. A total of 183 samples were collected in Upo Wetlands. The results showed that there were significant differences in the tourists' environmental attitudes between pre and post-participation ecotourism activities. This indicates that ecotourism participants delicately reinforce their eco-friendly attitudes through various ecotourism experiences and educational programs. The most significant finding is that anti-environmental behavior can be relieved with eco-friendliness through participation in ecotourism.

The Korean government has administered the 'AMPQ-II' to all middle school students to prevent psychological problems and make immediate interventions when necessary. On the other hand, there has been a paucity of studies of the effectiveness of this governmental policy, or the factors influencing the effectiveness of the intervention. Using the data from 48 counselees from two middle schools, the present study examined the effectiveness of the intervention programs, and whether the counselor's characteristics and the number of counseling sessions might matter in the effect. The results suggested that most students reported improvements after the interventions. The intervention effect was less pronounced when the counselors had governmental certification. The number of counseling sessions was not a significant factor for predicting the effectiveness of the interventions. Interpretations of the present study should be made cautiously because of the small sample size. The present results, however, suggest that efforts to improve the quality of the counseling teachers are necessary. In addition, increasing the number of counseling sessions is not necessarily effective.

Recently, enterprises are protecting information assets with the various means of control and management. Nevertheless, they are confronted with the dilemma which the higher securitylevel they request, the lesser efficiency and productivity in short terms they acquire by the inconvenience of business process. In addition, in spite of the steady increase of organization's investment on information protection, the systematic way for the performance measurement of information protection has not been suggested, so that in reality, it is difficult to make the decision to invest on information-protection and elicit the direction to improve it. For this reason, this study intended to establish the concept of the protection and security of information assets of enterprises and to categorize the type of activities to protect information assets into management activity and control activity, and analyze the effects of management activity and control activity for information asset protection on the performance of information asset protection activity and organization. For this research, questionnaire survey was conducted with literature study and the PLS(Partial Least Square) was used to analyze the measurement model and hypotheses testing. The PLS analysis results indicate that management activity for information asset protection affects information asset protection performance. Further, organizational performance is influenced by information asset protection performance. Practical implications of these findings and future research implications are also discussed.

As crimes have increased to an extent that the police cannot cope with, there have been continuous discussions for the introduction of Private Investigation (hereafter PI) in Korea. However, attempts to legislate for the introduction of PI have failed every time PI bills for the introduction of PI were proposed. This was fundamentally because arguments both for and against the introduction of PI were sharply divided depending on the priorities. However, regardless of those clash of views, an apparent need for the legislation of PI service has arisen. As Korea opens its service market to other countries through GATS and FTAs, currently existing domestic PI law has been found to be inconsistent with international agreements such as GATS and KOREA-US(KORUS) FTA. This paper found that the Act on Usage and Protection of Credit Information which regulates PI service is inconsistent with the Article 12.4(a)(i) and (iii) of KORUS FTA and the Article 7.11 and the Article 7.13 of KOREA-EU FTA. If Korea does not modify the existing laws and establish new laws in relation to PI, such inconsistencies could lead to international trade disputes which could amount to billions of dollars. In this regard, the passage of the PI bill is necessary.

This study examines how individual, familial, and social factors are associated with persistent very low fertility in Busan Metropolitan City and contemplates family-friendly environments and social strategies for fertility increase. Fertility decline in Busan Metropolitan City recorded the lowest birth rate nationwide recent years among metropolitan cities and provinces in Korea. Birthrates are low partly because of multiple factors such as high age at childbearing and at marriage, decline in marriage, high divorce rate, the phenomena of marriage avoidance among unmarried women, traditional gender role attitude of men, low domestic work participation of husbands among dual career couples, low marital satisfaction and family life satisfaction, abortion, and more broader attiributes such as family policy, availability of childcare, education expenses, and family-friendlyness of a society. In addition, women of dual career couples in Busan strained from domestic work overload under traditional norms of gender role, and marital satisfaction recorded below average nationwide along with espeacially low marital satisfaction of wives compared to that of husbands. Major aspects of implications and considerations for higher birth rate and family friendly policy in Busan are discussed.
