In the case of the general helicopter among rotorcraft, length of the rotor blade for thrust-generation is longer than that of fuselage and tail rotor is required in order to compensate moment of the fuselage. For those reasons, enough space for take-off and landing should be secured and an accessibility for building is low. Also, the accidents caused by tail rotor occur frequently. However, the case of counter-rotating has merits that tail rotor is unnecessary as well as length of the rotor blade can be shortened but has a weakness that the weight of body is increased. In the present study, aerodynamic force measurement on single rotor system equipped with NACA0012 airfoil, which has aspect ratio of 6 and chord length of 35.5 mm, was carried out. And measurement was conducted with blade which has a half size of the former blade by using single motor counter-rotating. Aerodynamic force measurement was acquired by using 6-component balances and coefficients of thrust and power were derived along the pitch angle varying from 0$^{\circ}$ to 90$^{\circ}$ with the increment of 10$^{\circ}$. Those aerodynamic force data will be utilized for the design and production of brand-new counter-rotating rotor blade system which has same thrust with single blade system and provides a good accessibility to building by reducing its blade length.

Purpose - Domestic franchise market has been grown steadily, reaching 50 trillion won in sales and 3,360 franchise headquarters in 2014. A franchise system is an effective business system for the franchisees to lower the failure rate due to the fact that the inexperienced entrepreneurs are supported by their headquarters through the franchisee contract. However, there are also conflicts between franchiser and franchisee behind the quantitative growth of domestic franchise industry. Therefore, it is very important to structure the causes of conflicts and to examine the effect of factors on the relationship commitment and performances. Research design, data, and methodology - In this study, the author divides the composite incompatibility between the franchise and the franchisee into goal incongruity, domain dissensus, and perceptual differences, and examines each dimension to the relationship with commitment and performances. To verify the proposed research model and test hypotheses, the author selected 200 franchise responses in food and beverage industry. The data were analyzed using SPSS 18.0 and AMOS structural equation modeling program. Results - The empirical findings provide goal incongruity and perceptual differences have a negative effect on the affective commitment, but not the calculative commitment. In addition, affective commitment and calculative commitment are found to have a positive effect on re-contractual intention and extended brand shop running intention, respectively. Affective commitment have a stronger effect on re-contractual intention than calculative commitment. Conclusions - First of all, the fact that goal incongruity and perceptual differences negatively affect the affective commitment, but it does not affect the calculative commitment. It means the relationship commitment in distribution channel are multi-dimensional concept that may be attributed to emotional or affective dimensions but may exist in terms of necessity or power-dependence. Second, the level of relationship commitment such as affective and calculative commitment to franchise headquarters positively affects the re-contractual intention and franchiser's extend brand shop running intention suggest that franchiser should encourage and support existing franchisee's commitment. Third, the fact that affective commitment has a greater effect on relationship performance than calculative commitment means to induce franchisee's affective commitment and to prevent the inconsistency between goals and perceptual differences.

The purpose of this study is to review Hanliu phenomenon, a kind of social and cultural phenomenon, in China and to analyze its effects on the fashion style of new young generation of China. In this study, Hanliu phenomenon means the enthusiasm of Asian people for Korean mass culture including Korean dramas, pop songs, and fashions from late 1990s. This research adopts two kinds of methods for analyzing the phenomenon: qualitative and quantitative research methods. As a qualitative research method, we analyzed it with several sources of documentaries and audio-visual materials: articles from newspapers and magazines, special TV reports, and documentary movie files from Internet. As a quantitative research method, we surveyed approximately 100 female students of Beijing university and asked how they feel Korean culture and fashions. The Hanliu phenomenon led to the popularity of Korean products as well as general culture of Korea. Also, it influenced Chinese young generation so much that Korean fashion has become prevailing. Such influence on the street fashion of Chinese youths can be summarized in three factors as follows: First, Korean entertainers' fashion is widely imitated. For example, H.O.T-like hairstyles, hip-hop styles, large heel shoes with boots-cut pants, and long-curled permanent hairstyles have been on among Chinese youths. Second, the preference for Korean fashion products has highly increased. The number of stores dealing with Korean fashion products has increased. Even the 'Kim Hee Seen,' a fashion brand named after a famous Korean actress, was introduced. Finally, Korean culture and products have widely been imitated in China as much as the increasing popularity of Korean fashion products. This study reveals that Hanliu phenomenon is widespread in China, and Chinese youths are largely affected by the fashion styles of Korean entertainers. Also, Korean fashion products are largely imitated and benchmarked in China. Hanliu phenomenon is a big chance to approach the fashion market of China, the largest buying power in the world. To make inroads into the Chinese fashion market, we suggest that we need to have our own brand and to make the most of culture, stars, and Internet in marketing. Also, we need a well-planned strategy for a success in the Chinese fashion market.

Fashion cultural products represents cultural trend, and they are produced a lot in Korea to express the Korean culture and style. They are also tools that embody images of Korea. This study mainly focuses on the Korean traditional-patterned ornaments as fashion cultural products. Therefore, this study aims at developing a framework of consumers' attitudes and consumption behaviors about Korean traditional-patterned ornaments, examining how the characteristics are changed according to shopping orientation. For this purpose, a quantitative survey was carried out using 455 questionnaires from women in their 20s and over. The data were analyzed using frequency analysis, factor analysis, t-test, ANOVA, cluster analysis, and $x^2$-test. Findings of this study were as follows. First, half of the respondents were found to possess Korean traditional-patterned ornaments. However, consumers had positive attitudes and tend to purchase them for their own use rather than gifts, demonstrating that the potential for the market is large enough. Second, in accordance with their shopping orientation, consumers were sub-divided into four groups: trend/brand oriented, practicality/pleasure oriented, convenience oriented, and passive shoppers. The trend/brand oriented group showed highest levels of preference regarding purchase intentions of Korean traditional-patterned ornaments. This group also showed the strongest purchasing power on fashion items among the four groups. Third, this study presented animal, plant, geometric and abstract patterns to the respondents to examine their attitudes. It was found that consumers prefered plant-patterned ornaments rather than the others, demonstrating that they have stronger preference and purchase intention toward ornaments with more natural images.
