The purpose of this paper is to evaluate supply factors of urban parks to answer the research question: What are the causal effects of supply factors of urban parks on visitor satisfaction? After reviewing the literature and the Korean park planning process, we constructed a conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 452 visitors at 8 urban parks in Daegu Metropolitan City in 2008, based on a stratified sampling method. After the elimination of 96 unsuitable samples, we have analyzed the data using descriptive statistical methods, Pearson's correlation analysis and a path analysis method. We have found that: 1) While the direct and indirect effect of accessibility(ACC) on visitor satisfaction(VS) turned out to be 0.184 and 0.220, respectively, the indirect effect of information(IFM) and promotion(PRM) on VS turned out to be 0.101 and 0.177, respectively. 2) While the direct and indirect effect of service(SVR) on VS turned out to be 0.130 and 0.236, respectively, the direct effect of ACC turned out to be 0.698. 3) While the direct effect of ACC, SVR and attraction(ATT) on VS turned out to be 0.184, 0.130 and 0.698, respectively, composing 67.96% of causal effect, the indirect effect of ACC, IFM, PRM and SVR on VS turned out to be 0.220, 0.101, 0.177 and 0.236, respectively, composing 42.04% of causal effect. 4) The magnitude of causal effect of supply factors on VS turned out to be ATT(39.98%), ACC(23.14%), SVR(20.96%), PRM(10.14%) and IFM(5.78%) in order, and 5) the causal effect of external supply factors of ACC, IFM and PRM compose 39.06% of the causal effect while that of the internal supply factors of SVR and ATT is 69.94%. The research results suggest that: 1) Planning for park marketing strategy and remedial directions for existing urban parks, in order to increase visitor satisfaction, be focused on IFM and PRM, especially. 2) The research approach and path analysis method adopted by this research be valid and highly useful for planning and evaluation of other recreation areas. It is recommended that: 1) Structural Equation Model on supply factors of urban parks be established in the future. 2) Evaluation of supply factors by type of urban park be performed.

North Korea conducted a total of six nuclear tests from the 1st test of 2006 to September, 2017. North Korea developed an armed forces security strategy at the level of regime protection and defense to respond to U.S. hostile policy. However, it is certain that strategic goals of North Korea's nuclear test were to overcome a crisis in North Korea's regime through US-North Korea negotiation and complete nuclear armed forces for socialist unification on the Korean Peninsula. North Korea's continuous nuclear test is a direct factor in threatening peace on the Korean Peninsula and an indirect factor in security dynamics of Northeast Asia. The U.N. Security Council has enforced sanctions against North Korea through six resolutions against North Korea's reckless nuclear test for the past 10 years. However, Kim Jong-Un's regime is in a position to stick to simultaneous pursuit of nuclear and economic development in spite of anti-North sanction of international society including U.N. and U.S.A. It is understood that North Korea was stimulated to conduct intense nuclear test as U.N. and U.S.A's anti-North sanction was not effective on North Korea. Full-scale and local wars are expected as military options, one of anti-North sanctions of the Trump administration. The Trump administration has attempted diplomatic pressure strategy as a secondary boycott unlike previous administrations. Nevertheless, North Korea has stood against U.N. and U.S.A's anti-North sanction with brinkmanship tactics, announcing full-scale military confrontation against U.S. It is judged that North Korea will pursue simultaneous nuclear weapons and economic development in terms of regime survival. North Korea will have less strategic choices in that its regime may collapse because of realistic national strategy between U.S.A. and China.

The purpose of this study was to evaluate the long term effect of school-based oral health program on decrease of dental caries among elementary school children. The subjects of this study were total 727 students of one elementary school in Deagu, Korea. They had received school-based oral health programs for more than one year since 2004. This school-based oral health program included regular oral examination, fluoride mouth-rinsing, pit-and-fissure sealing, APF gel application, tooth brushing instruction and take the xylitol tablet after lunch during school days. The subjects' oral health status were examined by two calibrated dentists every year from 2004 to 2009. The DMFS index of $1^{st}$ grade to $6^{th}$ grade experimental and control group was 0.07, 0.39, 0.55, 0.67, 0.81, 1.79 and 0.31, 0.86, 1.07, 1.04, 2.71, 3.08 respectively. It's significantly different in $5^{th}$ grade(p<0.001) and $6^{th}$ grade(p=0.018) when it compare with control group. This study partially showed effect of school-based oral health programs on decrements of dental caries. This program should be expanded widely among elementary school in Korea. Xylitol tablet also recommended to included in school-based oral health programs.

The purpose of this study was to examine the oral health behavior and awareness of teachers in community children's centers, the state of oral health care among children in the centers and the opinions of the teachers on child oral health education in a bid to gather information required for the development of oral health education programs geared toward community children's center teachers. The subjects in this study were 178 teachers who worked in 98 community children's centers in the city of Incheon. After a survey was conducted from April 28 to June 4, 2010, the collected data were analyzed. The findings of the study were as follows: The 57.3% of the teachers investigated provided toothbrushing guidance from time to time or couldn't do it at all. As for the reason why toothbrushing guidance was scarcely conducted, the largest group cited shortage of sinks(27.5%) as the reason, and the second biggest group replied they couldn't afford to pay attention to that due to heavy workload(20.6%). The third greatest group was pressed for time(16.7%). The teachers got a mean of 3.27 in oral health behavior, and 87.7% were concerned about children's oral health. The group of teachers who ever received oral health education was significantly better at oral health behavior and showed significant more interest in oral health(p<0.01). The 97.2% of the respondents considered oral health important. Concerning the reason, they replied it was crucial for systemic health (74.2%). The 89.4% of the teachers viewed child oral health education as necessary, and 86.5% had an intention to provide oral health education for children. They hoped to receive education on the oral health control act(4.52) and the prevention of dental caries(4.40). The above-mentioned findings confirmed that in order to step up the oral health promotion of child users of local children's centers, it's necessary to provide secondhand education for them through their teachers who have a great impact on them. Therefore the development of oral health education programs that cater to local children's center teachers is required.

This study was to investigate the level of knowledge, recognition, behavior of radiographic safety control and job stress in dental hygienists and to determine the relationship among variables. The subjects were 256(56.9%), who were worked in dental hospital and clinic with mean age of $29.59{\pm}7.30$. Data was collected using a self administrated questionnaire from April 4 to May 15, 2010. Behavior of radiographic safety control was measured using the 15-items and job stress was measured using the 5-items with 5-point likert scale. The data were analyzed with t-test, one-way ANOVA and pearson correlation coefficient using the SPSS WIN 17.0 program. Regarding job stress, the subjects was a mean of 2.63 out of a maximum 5 points. The level of knowledge, recognition, behavior of radiographic safety control a mean of 3.11, 4.08 and 3.43 out of a maximum 5 points. Recognition and behavior of radiographic safety control was negative related job stress in this study. Based on the findings, behavior of radiographic safety control is associated with job stress. These results suggest that various program should be considered for radiation safety control of dental hygienists.

This study was designed to identify the relationship between emotional labor and reaction factor(job satisfaction, fatigue), buffer factor(social support) among dental hygienist. The number of respondents was 50 who work in dental clinic and period of investigation was march 2010 through April 2010. A structured questionnaire was employed to evaluate the level of participants' sociodemographics, job-related factors, health-related behaviors, emotional labor and self-perceived fatigue, job satisfaction, social support. While the mean values of emotional labor were higher than thosewho work in hospital and lower than those who work in service employees. These results suggest that emotional labor was related to an increase in fatigue and strong correlation between involuntary emotional expression, self-perceived fatigue, job satisfaction, social support in dental hygienist. Multiple regression analysis has found that social support and no. of personnel were main factors that influence to the level of emotional labor in dental hygienist. The results of this study suggest that emotional labor was a determinant predictor of self perceived fatigue. Thus, a management program for emotional labor is strongly recommended for promotion of quality of life in dental hygienist and to improve dental service and competitiveness.

Over the period between January 1997 and December 1998, herbal medicine was more than three times administered to the patients coming to Na dong gyu's Oriental Medical Clinic on account of the symptom of growth deficiency. According to radiological opinions about the patients providing cooperation for measuring their height and weight as well as their bone age every three months, it was found that the growth plates were not closed. A research was conducted for 200 children randomly selected of patients in prepuberty (they grew by less than 5cm a year before treatment at a age of 12years for female children and 14years for male children). As a result, the following conclusion was drawn: 1. The randomly selected subjects were made up of 116 male and 84 female children in terms of gender. The age direstribution was most 10 to 12 years in 86 children(34.00%), followed by 8-10 years(27.50%) and 12 to 14 years(19.50%). 2. Considering the distribution of sick children's parental height, the fathers of 141 children(70.50%) measured less than 170cm high, the subaverage height, while the mothers of 172 children(86%) measured less than 160cm high, the subaverage height. It was shown that sick childen's height was genetically influenced by their parents. 3. Children patients's weight at a time of birth was most 3.1-3.5kg for 85 children(44%) and less than 2.5kg which came under the range of growth dificiency for 19 children(9.5%). 4. The highest proportian of the children patients with growth dificiency(56.33%) had the symptom of digestive disorders, of which 77 children patients(18.78%) had anorexia, 16.59% of children patients had the high level of respiratory disorders. Both the digestive disorder and the respiratory disorder put together, they had the high rate of 72.92%. Therefore, this indicates that both the digestive disorder and the respiratory disorder have a great effect on children's growth dificiency. 10.74% of chilren patients were shown to have allergic disorders, which indicates that they also exert an effect on growth deficiency. Specifically, 7.07% of the children patients had the high level of obesity, which shows that an excessive uptake of nutrition may rather induce children to have growth dificiency though an appropriate amount of nutritional uptake is necessary. 5. Comparing their bone age and their chronological age, 58 children patients(29.00%) showed that they were the same at the highest percent. 79 children patients(39.50%) showed that thier bone age was lower than their chronological age. And 63 children patients(31.50%) showed that their bone age was higher than their chronological age. 6. As regards the prescription administered to children patients for treating their growth dificiency, Growth tang A related to the kidney, the congenital factor, of the causes for growth dificiency in traditional Oriental Medicine was administered to 108 children patients(54%), whereas the Growth tang B related to the spleen, the acquired factor, was administered to 92 children patients(46%). 7. 116 male children patients with growth dificiency had the average value of growth for one year before treatment, 4.39cm, while 84 female children patients had the average value of growth for one year before treatment, 4.24cm. A total of 200 children had the average value of growth for one year before treatment, 4.33cm. The annual average value of growth in growth curve surveyed by the Korea Pediatrics Society was 5.79cm. Compared to this value, the one year average value of growth for 108 male and female children patients taking Growth tang A was shown be 8.44cm, which indicates a greater growth by 4.12cm(95.37%) in comparison with the average value of growth before treatment, 4.32cm, and a greater growth by 2.65cm(45.77%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Also, the average value of growth before treatment for 92 male and female children patients taking Growth tang B was shown to be 8.47cm, which indicates a greater increase by 4.15cm(96.06%) compared to 4.32cm, the average value of growth before treatment and a greater increase by 2.67cm(46.29%) in comparison with 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Considering the average value of growth for male and female children patients taking Growth tang A and B, it was shown to be 8.46cm, which indicates a greater increase by 4.14cm(95.81%) compared to 4.32cm, the average value of growth before treatment, and a greater increase by 2.67cm(46.11%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society.

The study, executed with Hallasan National Park, which deserves to be a typical ecotourism destination, aims to provide basic information on park management for early establishment of ecotourism in a national park by assessing its visitors' behavior and satisfaction with a nature trail established as a series of an environmental interpretation program. The questionnaire survey was conducted at Eorimok Square in the weekday and on the weekend for two months of August and September in 2006, and finally 144 valid samples were used for the analysis. As a result of the research, it revealed that the demographic characteristics of the visitors to Hallasan National Park tended to coincide with those of the visitors to other national parks In Korea. On the whole, it showed their low recognition level of nature trails built up in national parks and less experience in using them. However, the visitors' satisfaction level and intention of re-visit, and recommendation to others were comparatively higher after actually using the nature trail at the site of Hallasan National Park, which hints at the possibility of national parks' much weightier role as the ground for ecology education and the functional expansion of the environmental interpretation-related facilities and programs. As for the attributes having effects on users' satisfaction with a nature trail, substantial aspects such as accessibility, safety, uniqueness and interest in environmental interpretation, and educational quality as well as physical facility management were revealed to have equal effects on users' satisfaction level, so there still remain a lot of pending issues over the reality of national parks in the initial stage of ecotourism staying at the level of the introduction and establishment of the facilities for environmental interpretation. This research had surveyed visitors to Hallasan National Park and limited to the nature trail only. For more systematic and practical ecological management of a national park, the in-depth understanding of the attributes affecting satisfaction of ecotourists, including nature trails and other environmental interpretation programs, and more sophisticated measuring tools are needed.

This study, as a case where the environmental conflict and dispute arose between the use and the conservation as in the other protected areas in Korea, took the first step to build ecological citizenship to solve various and complicated issues in a fundamental level by providing a basic information on differentiated environmental perceptions of the locality and the visitors of Seoraksan National Park. The questionnaire survey was employed on September 6th and 7th with 150 residents of the park area and 200 visitors of Osaek-Daechungbong trail. Total number of 13 survey questions was introduced using Dunlap and Liere's NEP index. The result shows that the perception of 'balance of nature' was more dominant to the perception of 'humans over nature' and the perception to the 'limits to growth' was also somewhat positive in both groups. The differences in environmental perceptions between the groups exist; the visitor group tended to have more positive level of acceptance of NEP views. Such differences in perceptions suggest that a different normative approach should be taken to the residents of the national park with less pro-environment in their perceptions when policy making. It thus seemed possible that ecological citizenship could be realized since the younger and the higher education level are, the more pro-environment. The findings of the research may cause some concerns however, because the study has been confined as a case study with basic understanding of environmental perceptions and its differences between the interest groups. More extensive research is required to confirm if this is generalized.

These studies were carried out to investigate the bionomics of Gonatocerus sp. y (Hymenoptera: Mymaridae) , an egg parasite of the green rice leafhopper, Nephotettix cincticeps Uhler (Homoptera: Deltocephalidae) under laboratory and field conditions at Gyeongnam Provincial O.R.D. in Jinju from 1982 to 1983. The developmental period of each life stage was observed under four different temperature conditions from $15^{\circ}C\;to\;30^{\circ}C\;with\;5^{\circ}C$ increment. The development from egg to adult at 15^{\circ}C,\;20^{\circ}C,\;25^{\circ}C,\;and\;30^{\circ}C $ was completed in an average of 53, 25, 15, and 12 days and the females laid an average of 28, 48, 42, and 32 eggs respectively, with a maximum of 98. And most of the eggs were laid in the first two days after emergence. The time of adult emergence was determined under $25{\pm}1^{\circ}C$ condition. More than $76\%$ of the wasps emerged in the morning and the rest of them emerged in the afternoon. The average sex ratio between male and female was 1 : 5 when the wasps were developed from fertilized eggs. The longevity of female was greater than that of male when honey and water were provided as food, however, it was not when only water was supplied as food. The average longevities of females were 30 days at $15^{\circ}C$ and 15 days at $20^{\circ}C$ when honey and water were given as food. The peak precent parasitism of Gonatocerus sp. v on Nephotettix cincticeps in fallow fields was observed between late April and early May. The percent parasitism of the wasps In fallow fields was an average of 49\~59.9\% $ in Gyeochang, Namji and $23.2\~36\%$ in Namhae. The parasitic activities of the parasite had four peaks in paddy field, however, the highest peak was observed between late August and early September. The Percent e99 Parasitism of Gonatocerus sp. y was an average of $12.3\%$ on second the generation and $24.6\%$ of third genera lion of Nephotettix cinrticeps.
