This study investigated the contents of twitters of metropolitans by year and city using language network analysis. The possibility of twitter as a medium of information provision was also explored. This study employed KrKwic, Ucinet6, and Netdraw programs to conduct language network analysis. As the results, the network was mainly formed with information about civic administration (citizen, management, opening service, participation) and information about citizens living (cultural events, parks, way to work) in 2014. However, information about civic service and announcement (citizen, civic opinion, opening service, civic service, events) occupied a central role in the network of 2015. The results showed that different keywords were derived by year and city in network analysis by city.

Most of cultural area which people enjoy and consume is kitsch culture, though the culture is barely acknowledged. In this multimedia era, people create, publish and enjoy contents of 'webtoon(web+cartoon)', which is relatively faster and more convenient to enjoy comparing to published cartoon. Contrarily to its physical growth, the webtoon shows difficulty in advancing with other genres, is full of irritative factors and contents, and has tough time to become more sophisticated one. This study derived characteristics of kitsch in webtoon, suggested the way of webtoon as an art by analyzing conditions and usage motivation of webtoon. The conditions of kitsch are uniformity of mass consumption, popular vein, catharsis, vicarious satisfaction, immediate feedback-requiring image flood, and reproduction of techniques. The usage motivations of webtoon are studied as pursuit of information, entertainment, relaxation, socialization, convenience, and effectiveness. Usage motivation factors in webtoon and kitsch culture are almost identical. Contrary to its past of being underestimated and vulgarly considered, kitsch is acknowledged as an 'kitsch art'. By studying the process of becoming an art, the study has its purpose to suggest the experimental and developing way to make webtoon be acknowledged as 'webtoon art'.

This study aimed to develop and pilot-test educational program prototypes of training health coaches to help cancer patients overcome crises and create positive growth. For this purpose, the educational contents and methods of the blended learning program prototypes were derived through learner needs and literature analysis. The prototypes, which consist of introducing of health management and health information and understanding and practice of basic coaching and health coaching, were developed to integrate with four sessions of face-to-face, off-line classes, training practices through 12 tele-classes, and use of online learning system. The prototypes were conducted and pilot-tested by a total of 35 students selected through the document screening and the interview. After participating in the blended learning program, learners expressed greater overall satisfaction with each session program (average score = 4.36, with 5 being most satisfied), satisfaction with learning contents (average score=4.42) satisfaction with course preparation (average score = 4.26) and satisfaction with lecture materials (average score = 4.19). The results of this study show that a systematic and integrative approach for designing a blended learning program can be useful for various educational needs in health and medical fields. In the future, empirical studies are expected to see how these curricula are actually implemented and assess whether the intended learning outcomes are achieved.

EDI is basically the concept of computer-to-computer exchange of messages relating to various types of activities or business areas, such as banking, trade, medicine, publishing, etc. Therefore, security, reliability and special functionality will be implicit requirements of EDI systems. We will design access control model to content security of these requirements. Access controls in information systems are responsible for ensuring that all direct access to the entities occur exclusively according to the access modes and rules fixed by security policies. On this paper, security policies for access control model are presented from the viewpoints of identity-based, rule-based, role-based policy. We give a design of access control model for secure EDI service based on the derived access control rules and operations to enforce the defined security policies. The proposed access control model provides integrity, confidentiality and a flow control of EDI messages.

This experiment was carried out to compare soil moisture contents and the amounts of irrigation water by varying irrigating methods for chinese cabbages. The irrigating methods were non-irrigation (Plot A), furrow irrigation(Plot B). fixed nozzle pipe irrigation(Plot C), subsoil pipeline irrigation at the depths of 15cm. and 30cm., laying out in the middle of the rows of chinese cabbages(Plot D) and subsoil pipeline irrigation at the depths of 15cm, and 30cm., laying out beneath the rows of the roots of chinese cabbages(Plot E). In this experiment soil moisture contents were measured by using a simple electric device. As a result, the fallowing items are derived; 1) A significionce of 5% was observed between the yields produced at the furrow irrigation plot and fixed nozzle pipe irrigation plot, and those at the non-irrigation plot and subsoil pipe-line irrigation plot. 2) In the subsoil pipe-line irrgatiion, the Plot D type was observed to be slightly better than the Plot E type in the effect of the growth of cabbages. 3) The ratio of the amounts of irrigation water applied in the furrow irrigation plot, fixed nozzle pipe irrigation plot and subsoil pipe-line irrigation plot is approximately 3.2:2.1.

PURPOSES : This study deals with the working life of polymer concrete, which is typically used as a repair or overlay material for portland cement concrete pavements. METHODS : In the scope of this study, laboratory testing was conducted on fresh MMA modified UP polymer concrete, which uses an MMA monomer for viscosity adjustment and strength improvement of UP resin. The experimental variables were temperature (-20 to $+20^{\circ}C$) and binder components (MMA, MEKPO, and DMA). RESULTS : The result showed that the optimum binder ratios for polymer concrete production were 12, 11, and 10 wt.% when the MMA contents were 20, 30, and 40 wt.%, respectively. The working life of polymer concrete depending on temperature and binder components could be expressed by a logarithmic functional formula. The coefficient of variation for each binder component was the highest for DMA content while the lowest for MEKPO content. Also, the contents of each binder component for ensuring the working life of 60 minutes were proposed. CONCLUSIONS : Ultimately, the present study derived a linear regression equation estimating 60 minutes working life based on the setting times of each binder component.

Human and animals are living by acclimation to environmental changes like high and cold temperature, nose, confinement, etc. If the above changes reach a defined levels, some physiological abnormal state could appear, which we call them as stress state. Catecholamines are excreted by the sympathetic-adrenomedullary system in free from in urine. Catecholamines are derived from the adrenal medulla and urinary epinephrine can be taken as a rough estemation of the activity of this gland. Many scientist reported the endocrinological change, excretion of catecholamine and its metabolites, stomach ulcer formation, etc. under the condition of the confinement and high temperature. In this study author gave restraint, electric shock and immersion stress to rats by administrating by HPLC and got the following results. 1. In the restriant experiment, epinephrine contents in control rat was 194.7 ng, but in Bohyulanshintang administered rat urine 198.9 ng of epinephrine was found. 2. In the electrical shock experiment, 199.5 ng of epinephrine was found in the control rat urine, but in Bohyulanshintang administered rat urine epinephrine content was 142.4 ng. 3. Dopamine contents in control rat urine the immersion environment was 118.9 ng, but in Bohyulanshintang administered rat urine only 55.2 ng of dopamine was found. 4. Incontrol rat stomach there appeared focal erosion and inflamatory exudate, but in experimental group these symptom were turned to mild condition.

The development of human-friendly game technologies understanding and responding to human emotion is a very crucial element in designing games. Out of emotion derived from games, this study attempted to define characteristics of games as a meaning representing the degree of reaching the targeted emotion. When examining most of researches regarding emotion, it has been noted that they tried to extract the most representative emotion through the systematization of emotional vocabulary and evaluate it by the association with the design elements in question. However, this definition would be beneficial only to understanding the direction of game entity and it could not express the emotion of concrete and objective players. Therefore, this study attempted to analyze the sense correlation of adjectives so as for emotional expressions to be represented accurately corresponding to players' intention, by using adjective thesaurus for the systematic understanding of such game entity.
