The advancement of medical technology has made it possible to treat various incurable diseases. Especially organ transplantation can give another life to the patients who have organ failure and could not find any other ways to treat their diseases. According to the development of medical technology and immunosuppressive drugs, the rate and extent of organ transplantation is increasing these days. New medical technologies like organ transplantation brought on critical issues and these have changed the way of thinking and morals that has been the fundamental rules in our society. Bioethics is already an important field of medicine and oriental medicine should investigate the problem caused by the development of medical technology and life science and should form a view of life in oriental medicine. Oriental medicine is East Asian traditional medicine based on "Huangdi-Neijing", constructed by the system of Jangfu and meridian. The traditional therapies of oriental medicine have completed a scientific system on the point of view that looks on human and nature equally. This process continued to form a new medical theory as the environment was changed and the new diseases were appeared since "Huangdi-Neijing" and "Shoganron" showed a new scope to investigate human and diseases. Therefore, it is important to develop the point of view of oriental medicine as the medical situation was changed. Oriental medicine has a holistic view that considers human as a little cosmos resonated by a big cosmos and regards the possibility to recover and to regulate the energy in our body. This theory is a basic idea of oriental philosophy. Oriental medicine focuses on the balance of yin and yang of the body and tries to harmonize the imbalance of yin and yang caused by the life style and environment. This can solve many problems that cannot be settled by modern medicine and this can accomplish the new paradigm of oriental medicine that is needed these days.

In this paper, the WEKA platform was used to mine and analyze measured data of floor failure depth and a prediction system of floor failure depth was developed with Java. Based on the standardization and discretization of 35-set measured data of floor failure depth in China, the grey correlation degree analysis on five factors affecting the floor failure depth was carried out. The correlation order from big to small is: mining depth, working face length, floor failure resistance, mining thickness, dip angle of coal seams. Naive Bayes model, neural network model and decision tree model were used for learning and training, and the accuracy of the confusion matrix, detailed accuracy and node error rate were analyzed. Finally, artificial neural network was concluded to be the optimal model. Based on Java language, a prediction system of floor failure depth was developed. With the easy operation in the system, the prediction from measured data and error analyses were performed for nine sets of data. The results show that the WEKA prediction formula has the smallest relative error and the best prediction effect. Besides, the applicability of WEKA prediction formula was analyzed. The results show that WEKA prediction has a better applicability under the coal seam mining depth of 110 m~550 m, dip angle of coal seams of 0°~15° and working face length of 30 m~135 m.

This study investigated elementary school students' understanding of basic functional relationships. It analyzed the written responses from a total of 2087 students of second, fourth, and sixth graders using tests that examined their understanding of five types of functional relationships. The results of this study showed that students tended to be more successful as their grades went up with regard to all the problem types. There were statistically differences among the three grade levels. Even lower graders were quite successful in dealing with additive relation, direct proportion, and inverse proportion. However the items dealing with square relation and linear relation were difficult even to sixth graders. It was common that students were good at completing the table by looking for a pattern from the given numbers but that they had difficulties in anticipating the value of 'y' when the value of 'x' is given either as a big number or as a symbol. Given these results, this paper includes issues and implications on how to foster functional thinking ability at the elementary school.

In the age of big data, distributed data providers need to ensure the privacy, while data analysts need to mine the value of data. Therefore, how to find the privacy-utility tradeoff has become a research hotspot. Besides, the adversary may have the background knowledge of the data source. Therefore, it is significant to solve the privacy-utility tradeoff problem in the distributed environment with side information. This paper proposes a distributed privacy-utility tradeoff method using distributed lossy source coding with side information, and quantitatively gives the privacy-utility tradeoff region and Rate-Distortion-Leakage region. Four results are shown in the simulation analysis. The first result is that both the source rate and the privacy leakage decrease with the increase of source distortion. The second result is that the finer relevance between the public data and private data of source, the finer perturbation of source needed to get the same privacy protection. The third result is that the greater the variance of the data source, the slighter distortion is chosen to ensure more data utility. The fourth result is that under the same privacy restriction, the slighter the variance of the side information, the less distortion of data source is chosen to ensure more data utility. Finally, the provided method is compared with current ones from five aspects to show the advantage of our method.

This study is aimed at comparing and analyzing the response of playfulness level by personality type of players, according to the observations and results of behavior shown in SNG (Social Network Game) players during their play, in particular based on social behavior of SNG players. For this, the behavior of SNG players is classified into SC (Social Connectedness) and NC (Non-Social Connectedness) by space where they play games and the relations between behavior of each SNG player and their playfulness are confirmed by empirical experiment based on big-five personality traits possible standards of disposition expected from players. The results are presented that the playfulness for behavior of SNG players has distinct features by personality types and there is a significant difference between personality types for SC behavior. It could be useful for determining the proportion of playing behavior for Social Connect, generally known as one of main sources SNG provides when designing SNG play and considering personality types of players.

X-ray plasma ejections often occurred around the impulsive phases of solar flares and have been well observed by the SXT aboard Yohkoh. Though the X-ray plasma ejections show various morphological shapes, there has been no attempt at classifying the morphological groups for a large sample of the X-ray plasma ejections. In this study, we have classified 137 X-ray plasma ejections according to their shape for the first time. Our classification criteria are as follows: (1) a loop type shows ejecting plasma with the shape of loops, (2) a spray type has a continuous stream of plasma without showing any typical shape, (3) a jet type shows collimated motions of plasma, (4) a confined ejection shows limited motions of plasma near a flaring site. As a result, we classified the flare-associated X-ray plasma ejections into five groups as follows: loop-type (60 events), spray-type (40 events), jet-type (11 events), confined ejection (18 events), and others (8 events). As an illustration, we presented time sequence images of several typical events to discuss their morphological characteristics, speed, CME association, and magnetic field configuration. We found that the jet-type events tend to have higher speeds and better association with CMEs than those of the loop-type events. It is also found that the CME association (11/11) of the jet-type events is much higher than that (5/18) of the confined ejections. These facts imply that the physical characteristics of the X-ray plasma ejections are closely associated with magnetic field configurations near the reconnection regions.

The paved areas in nonpoint source are highly polluted landuses because of high imperviousness and high pollutant mass emissions from vehicle activities. Particularly, the metal pollutants are a big issue in the paved area. It is usually washed-off during storms by adsorbing on sediments or soluble status. Therefore, this research was achieved for understanding the characteristics of metal pollutants in stormwater runoff in highways. Five monitoring sites were equipped with an automatic rainfall gage and an automatic flow meter. This manuscripts will summarize the washoff characteristics of metal pollutants and its concentration changes during storms. Usually first flush phenomenon was observed for all of the storm events and visibly confirmed with hydro- and polluto-graphs. Also it was coincided with the tendency of particulates and organic matters. The decrease rate per total reduced amount for metals during initial 30-min storm duration was obtained on 80%. The result may be able to use for determining the economical treatment criteria for stormwater runoff in highways.

On the 10th anniversary of China's accession to the WTO, the Chinese government issues White Paper to give a comprehensive introduction to China's foreign trade development. Through this paper, the Chinese government introduces I. Historic Progress in China's Foreign Trade II. Reform of and Improvements to China's Foreign Trade System III. The Development of China's Foreign Trade Contributes to the World Economy IV. Promoting Basically Balanced Growth of Foreign Trade V. Constructing All-round Economic and Trade Partnerships with Mutually Beneficial Cooperation VI. Realizing Sustainable Development of Foreign Trade. At present, the underlying impact of the international financial crisis, the protracted, arduous and complicated nature of the world economic recovery is manifesting itself, and the global economic structure and trade layout face in-depth readjustment. China will make new adjustments to its foreign trade, in an effort to turn foreign trade from scale expansion to quality and profit improvement, and from mainly relying on its low-cost advantage to enhancing its comprehensive competitive edge, thereby turning China from a big trading country to a strong trading power. China's foreign trade is still hampered by many uncertainties and is bound to meet new difficulties and challenges. During the 12th Five-year Plan period China will open itself wider to the outside world as a driver for further reform, development and innovation, make full use of its advantages, strengthen international cooperation in all respects. And at the same time China integrate itself into the world economy on a wider scale and at a higher level. China is willing to work with its trading partners to cope with the various challenges facing the world economy and trade, and promote its foreign trade to realize a more balanced, coordinated and sustainable development, and share prosperity and mutually beneficial results with its trading partners.

With the increased interest in the quality of life of modern people, the implementation of the five-day working week, the increase in traffic convenience, and the economic and social development, domestic and international travel is becoming commonplace. Furthermore, in the past, there were many cases of purchasing packaged goods of specialized travel agencies. However, as the development of the Internet improved the accessibility of information about the travel area, the tourist is changing the trend to plan the trip such as the choice of the destination. Web services have been introduced to recommend travel destinations and travel routes according to these needs of the customers. Therefore, after reviewing some of the most popular web services today, such as Stubby planner (http://www.stubbyplanner.com) and Earthtory (http://www.earthtory.com), they were supposed to be based on traditional Traveling Salesman Problems (TSPs), and the travel routes recommended by them included some practical limitations. That is, they were not considered important issues in the actual journey, such as the use of various transportation, travel expenses, the number of days, and lodging. Moreover, although to recommend travel destinations, there have been various studies such as using IoT (Internet of Things) technology and the analysis of cyberspatial Big Data on the web and SNS (Social Networking Service), there is little research to support travel routes considering the practical constraints. Therefore, this study proposes a new mathematical model for applying to travel route recommendation service, and it is verified by numerical experiments on travel to Jeju Island and trip to Europe including Germany, France and Czech Republic. It also expects to be able to provide more useful information to tourists in their travel plans through linkage with the services for recommending tourist attractions built in the Internet environment.
