Though various studies have analyzed the impact of physically being in the forest, consideration of the time factors is omitted in many of them. Since space and time mutually affect each other, the effects that resulted by the space factor can change when the time factor is introduced. In this paper, the focus was made on how the time spent in the forest influences the four resulting factors: live experiences, flow experiences, health perception and inner psychological perception. This research is based on the surveys taken from April to October, 2014. The focus of the questionnaire was to measure 'Live Experience (LE)', 'Flow (FL)', 'Health Perception (HP)' and 'Inner Psychological Perception (IPP)' levels among the participants. The respondents of the survey aged between 40 and 70, participating in Forest or ecological courses, living in the Northern area of Chungchungnam-do province of Korea. Additionally their past experiences ranged from as little as one year to as long as twenty years in forest related fields. It will be shown that the time spent in the forest affects the levels of LE, FL, HP, IPP, increasing them in proportion to the time with statistical significance. This result would be useful not only for those who are in charge of creating forest healing programs but also for people who study forest healing. Because the time spent in the forest influences the levels of LE, FL, HP, IPP, the forest healing programs will benefit by taking this result into consideration.

In order to suggest alternative directions for the regional development of Chungcheongbukdo through social network analysis (SNA) methods, this study highlights networking features of Chungcheongbukdo-based top 300 enterprises. In particular, it has paid attention to network relationships among participating enterprises and their basic structure, all of which play pivotal roles in provincial development. Major networking features among Chungcheongbukdo-based top 300 enterprises are dichotomized between structural and positional dimensions. Firstly, in terms of structural approach, this research confirms that both relational density indices and average connectivity levels among key enterprises have been extremely low. Therefore, the exchange networks seem relatively limited. That is, two enterprises could be interconnected after 1.1 stages in average, implying that the most popular types come from direct relationship among participating enterprises. In addition, this research finds that 7 major networks hinged upon 'distributed centralization types' present active information exchange, taking in charge of brokerage roles, all of which have contributed to broader network formation. Nonetheless, as the weight of minor network outweighs that of major network, more active supporting measures should be designed.

Clonorchiasis should be realized as an important public health problems in Korea by their wide distribution, high prevalence rate and heavy infection intensity. This study was designed to obtain the infection rate, contributing factors as well as the behavior of infected persons among the factory workers in Pohang area where that parasite still remains as a problem. Study was undertaken from September '86 to October '87. Clonorchiasis skin test was performed for 3180 factory workers, and stools of skin test positive reactors were examined. Praziquantel was prescribed to stool examination positive persons for clonorchis sinensis ova. After one year. stool examination was repeated for them who received medicine. At the same time. a structured questionnaire was given and the results were analyzed and compared with control group. The results of this study are summarized as follows; 1. The infection rate of Clonorchis sinensis. 1) Clonorchiassis skin test positive rate was $26.2\%$ (834/3180). 2) Stool(Clonorchis sinensis ova) positive rate among skin test positive reactors was $21.6\%$ (129/598) All 129 infected persons were male. 2. Contributing factors of Clonorchis sinensis infection. 1) The chance of infection was higher in low-educated peple(p<0.01) 2) Stool(Clonorchis sinensis ova)positive rate was higher among the persons who reside near the riverside now(p<0.01), or among the persons who long history of riverside residence(p<0.01) 3) The infection rate was higher in thoes who like sliced raw fresh water fishes than in those who like cooked fishes(p<0.05). 4) Correct answering rate for questions about the cause and route of Clonorchis sinensis infection was low in infected persons. 5) The infection rate was lower among those who had experience of previous clonorchiasis test(p<0.01). 6) Family members of infected persons show higher rates of infection(p <0.01). 3. Treatment effect and compliance of infected person to treatment. 1) After one year, negative stool conversion rate was $85.4\%$. 2) $70.8\%$ of infected persons took the medicine; Only $3.1\%$ of them consulted to physician to know the medication effect; As many as $29.4\%$ of them continued to consume raw fresh water fishes. As a conclusion, City of Pohang area, Hyung San River in the center, is an endemic area of clonorchiasis. Current clonorchiasis control system seemed to be ineffective; many of the skin test positive group did not submitted their stool for examination; only $70.8\%$ of infected persons took the medicine even though the drugs were given free of charge; $29.4\%$ continued to consume raw fresh water fishes after taking medicine. Therefore. proper education program should be provided to improve the compliance to treatment. Follow-up for infected cases is mandatory to prevent waste of restricted budget.

The purpose of this study was to examine the effect of a program geared toward improving elderly people's oral function. After a program was provided to the selected elderly people free of charge for three months, they were asked to rate their own oral function to see whether they underwent any changes after their participation in the program, and their oral function was tested to obtain objective data. The collected data were analyzed by the statistical package SPSS WIN 18.0. The findings of the study were as follows: As for changes in their self-rated indicators of oral function, they faced less troubles in most of the oral function items after they participated in the program, and there were statistically significant differences in some of the items. As a result of making an objective evaluation of their oral function, they underwent a little change in salivary flow rate from 1.19 to 1.30, though the change was not statistically significant. In terms of opening, they showed a statistically significant rise of scores from 4.22 to 4.53, and they also showed a statistically significant rise of scores in pronunciation from 30.52 to 38.88. Regarding satisfaction with the program, they gave 4.48 to the program, which implied that they were greatly satisfied with the program. The abovementioned findings suggest that oral health experts and program providers should try to encourage elderly people to keep on taking oral health programs with interest. Currently, oral exercise programs are conducted in some public health centers and in the field of clinical dentistry, and it's required to offer more oral exercise programs as community exercise programs for the elderly.

A number of organizations have had big interests in studies concerning leadership and not only academia but also psychological areas do also. Until now, leadership has been accentuated by managers or team leaders especially. Recently, however, the concept of self-leadership directing one's own activities through self-control or self-management is being focused on in practices and in academia. This study is to investigate the influence between self-leadership strategies as predictors and learning performance in IT classes as dependents variables mediated by attitude of attendance focused on the social science students in two universities (Korea(116 samples) and India(36 samples)). And this research tried to compare difference between two university students. As a result of empirical analysis, Korean learners making an effort by themselves show a tendency to think constructively. Namely, even though the level of difficulty may be high, by positive self-talk, respondents usually make an effort to get high academic performance. In case of Indian respondents, students who are in behavior-oriented show higher academic performance. Research results can give us direction of task-taking attitudes in firms or learning attitudes in teaching organizations and implications to human resource managers who are in charge of improving learning performance or productivity.

This article is considered how to utilize mime in the mudang gut. Actually, mime can't be the crux of mudang gut, and the only factors of mime is utilized. Therefore, the purpose of this article is to draw another nets of meanings in Mudang gut, not to study mime. First of all, I surveyed the constituent factors of mudang gut. One gutpan is combined with various factors. As a shamans(mudang), a musician, a jang gu player, a gongyangju(taking charge of food), a sibongja(helper for a shaman), and madangsoe (an under servant), they played their roles. The gut consists of equipment, food, clothes, music and dance. Next, I derived two nets of meaning out of considering a mudang gut performance of mudang (shaman). First, god in a general gutgeori appears expressing their existence by using mime with the music. Second, the following god appears expressing themselves using only mime without music. After showing who he is through action and facial expression, he continues to play a gut. Accordingly, mime of seoul gutpan plays a role to reveal the existence of god. Also, I divided the way of performing mudang gut into language performance and motions and then suggested that mime was mainly used in the motions. I surveyed a gutgeori using mime in the concrete. Through this, I suggested that the shaman used mime, when sending a deadman to the next world in a Jinogi gut. I suggested that mime was utilized repeatedly at the process of repelling the misfortune in a jaesu gut.

This study aims at comparing and analyzing early childhood education systems in both South and North Koreas and suggesting educational alternatives for integrating in various aspects based on it, in order to build directions of early childhood education system in the preparation of Unification. A comparative study on the early childhood education system in South and North Korea was done in terms of early childhood education, public education of early childhood. As a result, there were differences rather than similarities in many areas due to the differences of political ideology between the South and the North. First, early childhood is not compulsory, but becomes public in South, while it is partially compulsory and has an overall public system in North in terms of its compulsory education and Pulic education. Second, as a result of comparing operating systems depending on early childhood education institutions in the South and North, there were differences in various areas such as subjects of foundation, classification of age, operating types, etc. Third, looking at its administrative support system, two Koreas has a similarity of a overall dual system, but showed a specific difference. Fourth, its public support had a similarity that early childhood education is done free of charge in two Koreas. In light of the results of comparing the early childhood education system in South and North Korea, this study suggests the following implications. First, as part of an effort to restore similarities of the early childhood education system between two Koreas, a challenge that must be addressed with priority is to integrate early childhood education-nursery in the early childhood education for age 3-5. Second, we'll take an effort to include the early childhood education for age 3-5 in the basic disciplines with 'Making early childhood education public' being currently focused. In addition, we should an attitude to recover a similarity through mutual exchange and to have advantages of the early childhood education in two Koreas as a challenge of taking an effort to integrate the early childhood education in the South and the North various studies and debates, discussions will be made for the meaning of the early childhood education and the integration.

This study investigated the level of academic passion for pre-service elementary teachers' science pedagogical content knowledge (PCK) and the factors that influence the passion. To this end, 182 first to fourth grade students in advanced non-science majors who were taking science-related courses in the second semester were selected, and two tests were then administered to evaluate their academic passions for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participants. It was found that the factors such as "importance" and "harmonious passion" for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. On the other hand, the factors such as "like" and "investment of time and energy" were slightly higher than normal, and the factor such as "obsessive passion" was slightly lower than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to the high school track than the grade. The pre-service elementary teachers selected more often the factors such as "individual interests", "high school track", "contents of science-related courses at the university of education", "characteristics of professor in charge of science-related courses at the university of education", and "experience in teaching practicum" as the factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. However, there was a slight difference in the selection ratio depending on the high school track.
