Recently in South Korea, family-friendly living environment in resident communities have emerged as an important issue in addressing problems created by personalized and fragmented family in urban areas. Since their foundation in 2005, Healthy Family Support Centers provided a variety of community activities for both parents and children through the Co-Child Care Sharing Programs. That being said, it is certain that the Healthy Family Support Centers play a central role in making a family-friendly environment. This study surveyed the physical environment of the co-child care sharing space and suggested further improvement. The content of this survey represents the characteristics of co-child care sharing space in Incheon such as operation status, physical space, prepared facilities, and preference for facilities. This study also explored the field of two co-child sharing spaces (Bupyung-gu and Seo-gu) as an example case. The subject of this study was 14 co-child sharing spaces of nine Healthy Family Support Centers in Incheon investigated from July 2014 to October 2014. This study indicated three results: first, the size of the co-child care spaces, their composition and facilities are very different from each center and require standards and guidelines for the co-child sharing space in regards to physical space, composition, and facilities. Second, co-child sharing space should be provided with individual special programs and diversified activities in addition to playing activities. Third, many healthy family support centers operate over two co-child sharing spaces along with an out-located co-child sharing space that require mutual organizing and operational networking between each co-child sharing space to effectively share programs.

The load of this kind of gores, which is heavier than that of any other precedent, and on enormous seamless virtual world characterize the MMORPG(Massively Multiplayer Online Role-Playing Game) genres. In this seamless environment, gamers can usually accept a set of independent spaces, which is being held by independent game servers, os a single big virtual world. Despite the efforts of some developers, gamers are suffered from huge message traffic which comes from the interaction between client and server and the interaction between fold sowers. In this paper, new gore server architecture using MigAgent is proposed which tries to reduce message traffic. Usually, message traffic reaches the climax when a PC(Player Character) is moving to other field server. MigAgent, designed in this thesis, tries to manage this kind of PCs and to ploy o role of user's agent to prepare for the unexpected situation. Improvement of this system is shown by the analysis of the effect of the size ratio of AOI (Area of Interest) and AC (Adjacent Cell).

In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.

Objective: The present study aims to evaluate the visual reactions of users when they are playing games of different flow levels, and to explore the visual variables that can sensitively reflect the different flow levels. Background: The flow is defined as a psychological state where interface users feel their actions in a virtual setting identical to those in real environment. To measure the flow states of users, the questionnaire-based FSS(Flow State Scale) has mostly been used. However, this method is a qualitative test that has limits in terms of the accuracy of users' flow experiences. Therefore, more accurate methods to measure users' flow experiences are required. Method: Ten subjects participated in the experiment, where the independent variables were three games with different flow levels(puzzle games, dot drawing and coloring) and the time frame(the first and last 10 seconds in game playing), whereas the dependent variables included the pupil size and the frequency and duration of eye blinking. This study was a within-subject design. Each participant performed three types of games with different flow levels 3 times for each for 10 minutes, and their visual reactions to each game were measured. Results: The higher the flow cause the bigger pupil size(p<0.01) and the lower eye blinking frequency(p<0.1), indicating that different types of games lead to different flow levels. The pupil size during the last 10 seconds when the flow level was higher was bigger by 2.1% compared with that during the first 10 seconds in game playing(p<0.1), and the eye blinking frequency decreased by 12%(p<0.01). Conclusion: It was found out that the pupil size and the frequency and duration of eye blinking were psychophysiological indices for evaluating users' flow experiences, which could quantify the flow states users go through. The psychophysiological variables capable of measuring diverse aspects of the flow need diversifying to be applicable to precise measurement of the flow. Application: These studies are warranted for both quantitative analysis of flow levels and qualitative improvement of cyber leisure in line with development of healthy games.

The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

Purpose: This study was conducted to evaluate the effectiveness of a mother/infant-toddler health program developed to enhance parenting knowledge, behavior and confidence in low income mothers and home environment. Methods: A one-group pretest-posttest quasi-experimental design was used. Sixty-nine dyads of mothers and infant-toddlers (aged 0-36 months) were provided with weekly intervention for seven session. Each session consisted of three parts; first, educating to increase integrated knowledge related to the development of the infant/toddler including nutrition, first aid and home environment; second, counseling to share parenting experience among the mothers and to increase their nurturing confidence; third, playing with the infant/toddler to facilitate attachment-based parenting behavior for the mothers. Results: Following the programs, there were significant increases in parenting knowledge on nutrition and first aid. A significant improvement was found in attachment-based parenting behavior, but not in home safety practice. Nurturing confidence was not significantly increased. The program led to more positive home environment for infant/toddler's health and development. Conclusion: The findings provide evidence for mother-infant/toddler health program to improve parenting knowledge, attachment-based parenting behavior and better home environment in low income mothers.

Plastics of the marine environment are broken gradually down into smaller particles by chemical weathering, called "microplastic". Microplastics absorb organic pollutants that are persistent bioaccumulative substances. If marine animals ingested microplastic added to contaminant, it will lead to a bioaccumation through the food web. It eventually destroy health of marine environment and is harmful to marine top predators including humans. Also, Microplastics can impact marine animals by leaching the endocrine disruptor in microplastic itself as well as playing an adsorbent role of organic pollutants. Persistent and bioaccumulative substances in Korea have been regulated in terms of chemical risk but existing regulations largely have been limited in land-based source management of microplastic. Thus, the harmful impact will be increased whether the microplastics absorbed contaminants. To prevent risk of persistent bioaccumulative substances, this study suggests the following: (1) the strict management of microplastic by designating the hazardous substances, (2) expand the use of biodegradable plastic, (3) the effort for reuse and recycle, (4) the expand of microplastic clean-up programs.
