This paper investigates empirically the lead-lag relation between the 'apartment price index' and 'Internet search volume'. This study uses Naver Trend Index as a proxy for Internet search volume. An increase in Internet search volume on the apartment price index indicates an increase in people's attention to an apartment. Different from previous studies exploring the relation between 'the released price index of the apartment' and 'Naver Trend Index', this study investigates the relation of the Naver Trend Index with 'the fundamental price component of an apartment' and 'the transitory price component of an apartment', respectively. The results of the Granger causality test reveal that there are bidirectional Granger causalities between the 'released price' and Naver Trend Index. In addition, the 'fundamental price component of an apartment' and Naver Trend Index have a feedback relation, while 'the transitory price component of an apartment' Granger causes the Naver Trend Index uni-directionally. The impulse response function analysis indicates that the shock of apartment prices increases Naver Trend Index in the first month. Overall, The close relationship between apartment prices and Naver Trend Index suggests that increases in the movement of apartment prices are positively associated with public attention on the apartment market.

The purpose of this study is to examine the influence of LOHAS images of Japanese restaurants on customers' menu selection and satisfaction to provide useful information on proposing detailed marketing directions by deriving the importance and satisfaction factors of LOHAS images and to suggest practical and effective measures for using LOHAS images to improve menus at Japanese restaurants. The results of the study are as follows. First, as a result of examining hypothesis 1, "LOHAS images will influence essential factors," it was found that healthy ingredient, family-oriented, eco-friendly, sustainability, and energy-saving factors were influential. With greater family-oriented, sustainability, healthy ingredient, and eco-friendly factors in LOHAS image, interests in essential factors increased. Second, family-oriented, energy-saving, social-oriented, and sustainability factors in LOHAS image had a significantly positive impact on the environmental factors of menu. Third, eco-friendly, sustainability, family-oriented, energy-saving, healthy preparation, and healthy ingredient factors in LOHAS image had a significantly positive impact on customer satisfaction. Fourth, essential factors in the selection attributes of Japanese restaurant menu had a significantly positive impact on customer satisfaction. Fifth, environmental factors in Japanese restaurants had a significantly positive impact on customer satisfaction. The significance and limitation of this study are: first, Japanese restaurants would be able to build a better image with customers by providing menu items that are family-oriented, sustainable, and energy-saving. Second, it would be necessary to study how LOHAS factors influence customers' general purchase decisions and psychological factors.

Technology and fashion are not as distant from each other as it might first seem. Early wearables were functional but awkward to wear and to look at. Today wearables are rapidly rising to meet the fashion world on its own terms by producing garments that are both stylish and comfortable. Personalization of wearables allows for new modes of self-expression, which is an essential factor in making fashion items that appeal to the public. Embedded technologies in the garment and the functionalities integrated into the electronic textiles influence the ‘wearability', comfort and the aesthetic of a fashionable wearable. Considering these factors is an essential part of the design process when creating user-centered fashionable wearables. Designers have to have a comprehensive understanding of the purpose, the user, the interaction, and in commercial applications, the right price point. An appealing design in combination with an intuitive interface will make for a successful fashionable wearable.

A challenging topic was and still is the failure behavior of concrete beams without shear reinforcement. In spite of substantial experimental and theoretical efforts in the past, the mechanism of shear failure is not entirely understood. ALWAC is of importance to the current construction industry. Most of present concrete research focuses on high performance concrete, by which in meant a cost effective material that satisfies demanding performance requirements, including durability. The advantages of ALWAC are its reduced mass and improved thermal and acoustic insulation properties, while maintaining adequate strength. In spite of these advantages, its ultimate failure behavior has not been well defined for adequate design process. This paper will investigate mainly the shear behavior of reinforced ALWAC beam without web reinforcements numerically with experimental evidences.

Variability management is the foremost criterion that defines the extent to which complexities can be handled in a system. Predominantly, the requirements' engineering (RE) study overlooks, or speculates a consistent behavior of, the environment in which a system functions. In real-time systems it is vital to observe and adjust to an intrinsically changing context. Therefore, in this work we identify the requirements of the system in various contexts by recommending a framework using i* goal model, problem frames, use case maps and live sequence charts. The framework is illustrated using a case study of the smart grid RTP system. In the case study, elaboration of scenarios using use case maps and live sequence charts proved beneficial as they assisted in early analysis and validation of contexts. In addition, the elaboration of requirements for obstacle and conflict analysis assists the requirements engineer to increase the robustness of the system. The proposed framework is evaluated theoretically and by empirical study.

Present-day world economy is characterized by : technology nationalism, economic regionalism, market protectionism, multinational corporations, efc. All nations are striving for intensifying national economic rivalry and seeking after their own interests above everything else. Many regions of the world are also forming trading blocs, which could negatively affect nonmember states. The ultimate way to meet these difficulties is to establish production facilities in the countries imposing trade regulations. However, as the existing models of direct forrign investment (DFI) do not account for the particular nature of Korean firm's DFI activities, a new point of departure is imperative. It is because of this that Korean firms have only limited firm-specific advantages, the basic precondition of extant DFI theories, compared with their developed counterparts.

This study investigates how cultural differences between countries affect bilateral trade volumes, using Hofstede's cultural index that reflects nations' cultural characteristics. Empirical analyses of the impacts of Hofstede's five cultural characteristics on bilateral trade volumes are conducted either in each separate equation or simultaneously. Bilateral trade data of OECD countries plus China as of year 2010 is used for regression analysis on gravity model. Regression results from individual equation for each cultural index variable show tthe smaller the index gaps of power distances and uncertainty avoidance among countries, the larger bilateral trade volumes. On the contrary, the larger the index gaps of long-term orientation among countries, the larger bilateral trade volumes. If five Hofstede cultural indexes are regressed in a single equation, however, only variables of power distance and long-term orientation are significant. The analysis largely confirms that bilateral trade among countries with similar culture have much potrential to grow. It implies that policy actions for cultural proximity are very important for furthering bilateral trade.
