Social network games (SNGs), a rapidly growing online game genre, are built and played on social network sites. SNGs provide an online world for enjoying leisure time and interpersonal communication, and an increasing numbers of college students are involved in such game-playing as a leisure time activity. Despite the popularity, relatively few studies have been conducted to investigate the nature of game players, especially the meaning of such leisure time behavior by college students. This paper's aim was to explore a subjective meaning structure of online social network game play. The means-end chain model was used to link attributes of SNGs to the underlying values of game playing as a leisure activity. The results revealed two emerging end-values: the need for bridging and a sense of belonging. This study sheds light on the meaning of college students' leisure activities when playing social network games.

The East Asian Observatory (EAO) was established in 2014 by the East Asian Core Observatories Association (EACOA). The goal of the EAO is to build and operate world-class facilities on behalf of the East Asian regions, as a counterpart to the European Southern Observatory (ESO). Leading astronomical facilities such as ALMA, TMT, GMT, and SKA are mega projects which require enormous economic resources. It is difficult for any observatory or any country to fund such facilities on its own. EAO intends to combine the resources and manpower in our East Asian regions, in order to play a leading role in the next generation frontier instruments. The EACOA institutes: NAOC, NAOJ, KASI, and ASIAA, have authorized the EAO to take on the operations of the James Clerk Maxwell Telescope (JCMT) on Mauna Kea as their first joint venture. In this talk, we will report on the development of EAO, our current operations of JCMT, and our future aspirations.

Volleyball has become one of the world's most popular participatory sports in recent years. There are many dynamic skills and movements needed to play the game. As a result, many acute and overuse injuries to the shoulder may occur. This article addresses the common injuries and rehabilitation recommendations for the shoulder injuries in the volleyball players. The glenohumeral instability, primary or secondary impingement, internal impingement, labral injuries, and suprascapular nerve lesions are common problems in volleyball players. A basic knowledge of the biomechanics and volleyball maneuvers (blocking, serving, and spiking) can help in the development of appropriate trainging and reha- bilitation protocols. Special emphasis must be placed on the knowledge of muscular patterns involved in serving and spiking, because they typically require a strenuous unilateral action of the dominant shoulder. It is therefore impera- tive to include adequate stretching and muscular training programme for the prevention, as well as for therapy, of shoulder pain in volleyball players.

Dividend is one of essential factors determining the value of a firm. According to the valuation theory in finance, discounted cash flow (DCF) is the most popular and widely used method for the valuation of any asset. Since dividends play a key role in the pricing of a firm value by DCF, it is natural that the accurate prediction of future dividends should be most important work in the valuation. Although the dividend forecasting is of importance in the real world for the purpose of investment and financing decision, it is not easy for us to find good theoretical models which can predict future dividends accurately except Marsh and Merton (1987) model. Thus, if we can develop a better method than Marsh and Merton in the prediction of future dividends, it can contribute significantly to the enhancement of a firm value. Therefore, the most important goal of this study is to develop a better method than Marsh and Merton model by applying artificial intelligence techniques.

Recently, KSTAR, Korea's superconducting fusion energy research and development device, has succeeded in driving the high performance plasma for 70 seconds for the first time in the world. Continuous plasma operation technology is an essential factor for commercialization of fusion energy power generation. Therefore, this achievement is expected to play a major role in the research of fusion technology required for future fusion power plants. In order to operate the KSTAR, the discharge process in which the neutral gas is turned into the plasma should be preceded in the start-up (breakdown) phase of tokamak operation. This process essentially involves the vacuum environment in the tokamak device. KSTAR has successfully operated a vacuum pumping system to achieve the target level of the vacuum environment through a high temperature baking operation, a discharge cleaning process and boronization.

The study aimed at investigating the terms for each type of the current household furniture and at analyzing a standard based on those terms researched for the furniture, not including kitchen and child furniture. The study was conducted in sales and R&D division of major furniture brands such as Jang-In Gagu, Borneo, and Livart by surveying their staffs, and then, the investigated names were classified according to similar criteria and it was finally analyzed by the definite standard of the names made. In the results, the following 5 standards largely play roles for the naming. First, name according to requirements, second, construction of door, third, materials, fourth, shapes, and lastly, function. Except for the terms of "Sobari" expressed only as Japanese and "living room cabinet of Extension-type" using Korean and English along, most of the names show furniture in detail, and the names from Hangeul, Korean alphabet and from the English have recently and drastically increased with the lifestyle change influenced from Western world.

With a steep increase of the global disaster relief efforts around the world, the relief supply chain and humanitarian logistics play an important role to address this issue. A broad overview of operations research ranges from a principle or conceptual framework to analytical methodology and case study applied in this field. In this paper, we provide an overview of this challenging research area with emphasis on the corresponding optimization problems. The scope of this study begins with classification by the stage of the disaster lifecycle system. The characteristics of each optimization problem for the disaster supply chain are considered in detail as well as the logistics features. We found that the papers related to disaster relief can be grouped in three aspects in terms of logistics attributes: facility location, distribution model, and inventory model. Furthermore, the literature also analyzes objectives and solution algorithms proposed in each optimization model in order to discover insights, research gaps and findings. Finally, we offer future research directions based on our findings from the investigation of literature review.
