Inadequate and inappropriate intake of food is known to cause various health issues and diseases. Due to lack of concise information about healthy diet, people have to rely on medicines instead of taking preventive measures in food intake. Due to diversity in food components and large number of dietary sources, it is challenging to perform real-time selection of diet patterns that must fulfill one's nutrition needs. Particularly, selection of proper diet is critical for patients suffering from various diseases. In this article, we highlight the issue of selection of proper diet that must fulfill patients' nutrition requirements. To address this issue, we present a cloud based food recommendation system, called Diet-Right, for dietary recommendations based on users' pathological reports. The model uses ant colony algorithm to generate optimal food list and recommends suitable foods according to the values of pathological reports. Diet-Right can play a vital role in controlling various diseases. The experimental results show that compared to single node execution, the convergence time of parallel execution on cloud is approximately 12 times lower. Moreover, adequate accuracy is attainable by increasing the number of ants.

The purpose of this study is to assess the play and leisure status of children in Korea. The subjects of the study were 564 children in elementary, middle, and high school classes in four districts of Seoul and one rural district in Gyeonggi Province. We surveyed and analyzed the objects, time, place and cost of both play and leisure and investigated the differences according to age, region and sex. The results of this study can be summarized as follows. First, the children's play and leisure subjects were more likely to be friends than family members, and the proportion of fathers among the parents decreased with increasing age. Second, the children spent most of their play and leisure time on media related activities. Third, unlike in the past, the children's places of play and leisure were very diverse and included many adult or commercial places, such as cafes and karaoke studios. Fourth, there were no differences in the cost of play and leisure, depending on the age or sex of the children, but there were regional differences.

Increase of hypertext transfer protocol (HTTP)-based video popularity causes that broadband and Internet service providers' links transmit mainly multimedia content. Network planning, traffic engineering or congestion control requires understanding of the statistical properties of network traffic; therefore, it is desirable to investigate the characteristic of traffic traces generated, among others, by systems which employ adaptive bit-rate streaming. In our work, we investigate traffic originating from 120 client-server pairs, situated in an emulated laboratory environment, and multiplexed onto a single network link. We show that the structure of the traffic is distinct from the structure generated by first and second generation of HTTP video systems, and furthermore, not similar to the structure of general Internet traffic. The obtained traffic exhibits negative correlations, anti-persistence, and its distribution function is skewed to the right. Furthermore, we show that the traffic generated by clients employing the same or similar play-out strategies is positively correlated and synchronised (clustered), whereas traffic originated from different play-out strategies shows negative or no correlations.

Nowadays the preschool children spend much of the day playing indoors. Therefore, it needs the indoor environment that helps a variety of fun activities and physical development, and it requires the space configuration and playable furniture considering the emotional development for mental health. However, the furniture for fast growing preschoolers has not various types because the domestic furniture market for children is mostly baby beds and the furniture for the education of children. Therefore, this study presents the concepts and types of the playable furniture reflecting emotional design for preschool children's healthy emotion and suggests the most appropriate type of playable furniture considering play behavior by age. In this study, we investigated the physical, cognitive, social, emotional and linguistic development characteristics and play behavior of preschoolers, and derived the right type of playground equipment and furniture, and examined the types of playable furniture to help the emotional development. We derived the items to be checked for developing the playable furniture by age for emotional development, and classified preschoolers' playable furniture into the use of learning, relaxation and storage, and suggested its basic type focusing on the cases of various playable furniture developed at home and abroad. As a result, the playable furniture was divided into three types. The first is the self-play type making possible self amusement, the second is module built-up-type that consists of furniture and modules or units and creates various patterns and can be modified through the self-assembly and disassembly, and the third is IT game type grafting IT skills and a variety of electronic games to furniture. We sorted these types into three classes (1-3 years old, 4-5, 6-7) according to age and presented the type of play for each age, the play element and representative image that can be introduced to this furniture. In this study, we provided the basic design types of age-specific emotional playable furniture by analyzing these results.

Objectives: TMJ is the joint that connects the mandible to the skull, and it balances the body by holding the skull in the right position. The Meridian flows through the whole body. The objective of this study is to examine and clarify the relationship between the Temporomandibular Joint (TMJ) and the Meridian flow, especially around the TMJ. Methods: We reviewed the literature on the 8 Extra Meridians and the 12 Main Meridians around the TMJ. Results & Conclusion: Eight Extra Meridians keep the balance and harmony of the TMJ, and also play an important role in maintaining equilibrium of Yin and Yang of the whole body. The 12 Main Meridians, twelve Meridian Divergence (12經別) and Meridian Sinew also play an important role in the balance and harmony of the whole body based on the function of the Vicera and Bowels (臟腑). So it is conceivable that the role of TMJ is important in terms of health care.

Pilomatricoma is a benign tumor arising from the primitive basal cells of the epidermis that differentiate into hair matrix cells. Mutations in the CTNNB1 gene, which encodes β-catenin (a protein involved in hair growth), play an etiological role in the development of pilomatricoma. A 34-year-old woman presenting with a mass in the right parotid region underwent an excisional biopsy. The mass was conclusively diagnosed as pilomatricoma. During pregnancy, the mass grew from 1 cm to 5 cm in diameter and was accompanied by pain and tenderness. The growth may have been facilitated by the increased production of estrogen and progesterone, which bind to receptors located in the outer root sheath cells of the hair follicles. No recurrence was observed during 6 months of follow-up.

Background: TNF-$\alpha$ plays a major role in producing left ventricular dysfunction cardio-myopathy pulmonary edema and inhibits the compensatory mechanism of congestive heart failure. IL-6 is an acute reactant of immune reaction and also known to control immune reaction but its function in the myocyte was not clearly investigated. Author's performed this experiment to investigate the contents of TNF-$\alpha$ and IL-6 on the assumption that TNF-$\alpha$ and IL-6 may reside in nonfailing heart that has gone cardiac surgery and play some role in cardiac function. Material and Method : Right auricular tissues were sampled from 12 patients who had undergone total corrective surgery for both congenital and acquired heart diseases from January 1998 to June 1998 in Kosin Universcfy Gospel hospital. The quantitive analysis of TNF-$\alpha$ and IL-6 were assessed by ELISA method in right auricular tissue. Hemodynamic values about the pressure of ventricle atrium aorta pulmonary artery and cardiac index pulmonary and systemic vascular resistance and cardiac output were measured by echocardiography and cardiac catheterization and biochemical analyses of LDH & AST were done before operation. statistical analysis was by Paired Student t-test. Patients were divided into children(under 15 years olds) and adults groups and the data was compared beween two groups. Conclusion: Mild pulmonary hypertension and increased pulmonary vascular resistance were existed in both group. The contents of tissue TNF-$\alpha$ IL-6 in each group were independent of each data.

The scale of disasters is very large, also the influence of disasters is irreversible. Korean people has continuously learned how to deal with disaster management law. However, as time goes by after the many disaster, the concern with the disaster management by the people seems to become old and banal topic which nobody has interest in. If so, can it be said that our society is safe from the disaster? This study start from critical mind of asking this question. This study puts an emphasis on the problems such as following; To realize whole concept of disaster management provided in the basic civil defense law, the combined disaster management should be required to be established, the combined law should play a integral part for prevention for the disaster and should be a concrete basis of various laws for disaster management. Establishing a consolidated organization for disaster managing and united response organization is necessary. This consolidated organization is not temporary one such as civil disaster control headquarter but permanent one such as Disaster Management Office which controls an over all aspects of disaster management. Temporary organization should not be divided into natural calamity and man-made calamity but integrated one as a single control tower for all sorts of disasters. The police and army under fire fighting system should be reconsidered. It is necessary to make leadership system on the disaster place more substantial centered around present fire fighting system. To do so, more clear division of duty is required. The working condition should be improved so that all public servants in this agency can play their roles with pride and worth. The resource owned the existing administrative organization must be used by an appointment system. And to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. And the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, citizen's consciousness about safety supervision needs to be recover.
