The development of information technology are leading to the rapid evolution of SNS (Social Networking Services) in various directions and industries. Initially, SNS have been used as the form of networking between user's groups. Currently SNS has been developed towards multiple purposes and platforms such as the promotion and the advertising of a company. There are many SNSs including QQ, Weibo, and Wechat and so on in China. However, the use of companies in terms of advertising and information sharing with the customers do not meet the trend in China. Especially, there were little researches for Chinese travel agencies how to utilize SNS for attracting new customers and making them contribute to the firm's performance. In this study, we try to investigate the impact of the firm's characteristics and the usage of SNS on the performance of Chinese travel agencies. Based on Top 100 China travel agencies in 2009, we analyzed the relationships between firm's characteristics and the usage of SNS, and firm's performances in 2013. We expect that our study can contribute to the increasing academic and practical needs on the empirical evidence of the impacts of the SNS utilizations on the firm's performance.

A lot of studies of ship's economy are on the traditional fields such asreducing propulsion resistance, raising cargo handling rates and lessening building consts, but there are few researches on the merchant ship's economy concerning their deadweights and speeds according to shipping companies managerial cercumstances. Contrary to the contemporary trend that "the bigger, the better, if the cargo handling rate could increased sufficiently to hold down port time to that rate of smmaler vessels", this paper demonstrates the existence of certain limits in ship's size and speed according to the coditions of the freight rates, voyage distances, cargo handing rates, prices of fuel oil, interst rates etc. Fom the curves of criteria contour for various ship's deadweights and speeds which are depicted from the gird search method, one can get the costs and the yearly profit rates under the conditiions of large volume with long term contracts for the transportation of bulk cargoes. In estimating ship's transportation economy, the auther takes the position that the profit rate method is properer than the cost method, and introduces the calculation table of the voyage profit rate index. The use of the criteria contours will be of help to ship owners in determining the size and speed of the ship which will be built or purchased and serve in a certain trade route.

This study is aimed to specify the meaning of the body and the design trends in contemporary architecture. Architecture is based on the human life of various meaning, events, experiences, images, senses and interactions through the body. Thoughts, behaviors, and senses of human are interrelated in architectural experiences. Individuals experience the built environments and space, not through the ideas but through the senses and movements of the body. So, bodies make the real space of architecture. Contemporary architecture accepts the theory of phenomenology and places on the thoughts of Maurice Merleau-Ponty, Heidegger, Nroberg Schulz and so on. Such researches effect on the architectural trends to make design processes works on the programs in views of the expansion and the structuralization of human body. In detail, the aim of this study is to analyse the architecture as the fields of the subject with body as the center, design processes and principles changed form metaphysical thought to phenomenological discourse, and the design trends in contemporary architecture at last. In process of movements, vision centered architecture moves into the bodily experienced architecture and changed the trends from absolute form design to design of relative processes. In conclusion, architectural formation-dissolution-reconstitution of body creates the architectural thoughts such as human proportions, perspective space, ergonomics, modular, organic architecture, experience space, synesthesia, event architecture, fashion-invoked architecture, interactive surfaces, metamorphosis, and others.

Conventional researches on the behavior of fiber-reinforced and unreinforced soils often investigated the failure point. In this study, a concept is proposed in the comparison of the fiber-reinforced with unreinforced sand, by estimating the strength and strength ratio at different levels of strain. A comprehensive program of laboratory drained triaxial compression test was performed on compacted sand specimens, with and without date palm fiber. The fiber inclusion used in triaxial test specimens was form 0.25%-1.0% of the sand dry weight. The effect of the fiber inclusion and confining pressure at 0.5%, 1.0%, 1.5%, 3.0%, 6.0%, 9.0%, 12%, and 15% of the imposed strain levels on the specimen were considered and described. The results showed that, the trend and magnitude of the strength ratio is different for various strain levels. It also implies that, using failure strength from peak point or the strength corresponding to the axial strain of approximately 15% for evaluating the enhancement of strength or strength ratio, due to the reinforcement, may cause hazard and uncertainty in practical design. Therefore, it is necessary to consider the strength of fiber-reinforced specimen at the imposed strain level, compared to the unreinforced specimen.

Purpose: This study was to examine the trend of qualitative study published by Korean Journal of Adult Nursing from 1989 to 2011, and to suggest future directions through identifying its strength and weakness. Methods: Ninety one published qualitative studies were analyzed focusing on research methodology and research themes using descriptive statistics. Results: During the last 22 years, the number of qualitative studies has rapidly increased and the methodology used to analyze qualitative data has been diversified. The most frequently used analytic method was a phenomenology (48.4%) and the frequency of conducting a content analysis has increased. The prevailing data collection settings were community (61.5%), followed by hospital (35.2%). Especially, many researches showed specific description on researcher's efforts to get validity and reliability of studies in individual studies presented within recent 10 years. However, it was noted that meta study using mixed methodology and secondary analysis of qualitative studies are rarely used and need to be facilitated. Conclusion: Nursing Researchers utilizing qualitative research should continuously make efforts to increase the validity and reliability of their studies and to find knowledges or strategies applicable to practice through using mixed methods or secondary analysis of individual studies.

Today, games, movies and amusements are the occupation of museums. This study will investigate the current trend of the theme park-style museum, the alternative space of the 21th centuty. Theme parks have moved beyond the concept of park, and they have application in commercial space, medical space, educational space and other areas, even exhibition space in an advanced country. This study researches into the characteristics of the theme park and museum, and how the style of the theme park-style museum is created. Its aim is to analyze the character of theme Park-style museum through case study with a focus on style. The theme park-style museum is an exhibition space with an emphasis on the characteristics of a theme park. The style of a theme park-style museum can be divided into ride-type, food-type, character-type and landscape-type attractions. Attractions are an important element of theme park-style museum. We recognize the new paradigm of museum in the theme park-style museum, but need to propose a method that will apply attraction elements to an exhibition space. The theme park-style museum will continually evolve with new attractions, and it is recommended that museums plan today for these changes.
