This study identifies factors of Hanbok-trippers - a term for people who dress in Hanbok(Korean traditional costume) while going on a trip - who converge on Gyeongbokgung Palace by determining the characteristics of class, places to visit and preferred places. This study interprets the voluntary hobby activities of Hanbok-trippers from a viewpoint of a landscape prosumer and the meaning of the urban landscape. As a result of in-depth interviews, on-site survey, and observation surveys focused on Hanbok-trippers, there were various levels of participants. They are classified into three groups - leading group, entry group, temporary-experience group - according to their cognitions, types of Hanbok use, activities, etc. The leading group and entry group are a voluntary hobbyist class due to the ongoing tendencies of their participation. There are differences in the purpose and factors of visiting Gyeongbokgung Palace as a place for a Hanbok-trip. The leading group visited Gyeongbokgung Palace for cultural activities, regular get-together, public relations, and as a gathering place to go neighboring destinations. In this case, the main factors of the visit are the traditional landscape, convenient transportation, chances for traditional culture exhibitions and events in Gyeongbokgung Palace and its neighborhood. The entry group visits Gyeongbokgung Palace because of its traditional landscape and cultural activities nearby. The traditional landscape and many Hanbok-trippers are main factors of visiting Gyeongbokgung Palace for the Temporary-experience group. This study found that Gyeongbokgung Palace has a new sense of place of 'Introductory course of Hanbok-trip', 'Hanbok Playground' because temporary-experience group visits there to experience a Hanbok-trip for the first time. Hanbok-trippers consume places and landscape in actual places offline, producing a new landscape at the same time, and has the characteristics of a 'landscape prosumer' by producing landscape images online through their own personal or social media. Their colorful and voluntary movements contribute to the dynamism of the urban landscape and can become a new cultural asset for the city. The voluntary hobbyist class can be considered a new type of participants in bottom-up planning such as urban regeneration and place marketing. This study has significance in that it conceptualized the 'landscape prosumer' through the voluntary hobbyist class of Hanbok-trippers with the concept of the 'prosumer' that has been studied only in the consumer studies and marketing fields, and has identified the significance of the urban landscape.

Huam-dong is a representative area from the Japanese colonial period and is the space where most Japanese-style buildings remain in Seoul. Interest in modern cultural heritage continues to increase, including the registration of cultural properties in 2001, building assets in 2015, and the registration of cultural property units in 2018. As the debate continues over the necessity of preserving cultural heritage that reminds us of the Japanese colonial, there is a need for research to grasp the perceptions of stakeholders along with the perceived value of such spaces. This study identified the subjective perception types of the stakeholders concerned with the Japanese-style building group in Huam-dong, analyzed characteristics by types, and debated the issues. For this purpose, Q methodology, which is a statistical technique for measuring human self-subjectivity and extracting common human perspectives, was used. A literature study on the values of Huam-dong and modern cultural heritage was conducted, and a Q questionnaire based on five aspects of modern cultural heritage values (historical, architectural, sociocultural, landscape, and economic) was applied. The results of the study depicted three types of cognition and showed different attitudes toward the Japanese building group. This study found a conflict comparing the perceptional differences between the types of cognition. This study is meaningful in that it provides an in-depth approach to the perspectives of the stakeholders concerned with the Japanese-style buildings clustered in central Seoul. It is also meant to present a theoretical framework that can be applied to the use area as sustainable cultural heritage through the establishment of preservation and utilization of Japanese-style areas and conflict resolution.

This study was attempted to examine relationship between personality traits and job satisfaction of community health practitioners(CHPs) working in remote rural area in order to suggest some methods to enhance their lob performance and the degrees of job satisfaction. The General Personality Test and the revised version of Job Satisfaction Questionnaire were administered to 200 of 348 CHPs in the Kwangju-Chonnam area and then the percentages, means, standard deviations and Pearson's correlation coefficients of these data were obtained, ANOVA and logistic analysis were used. The results of study were as follows : 1. CHPs without religion were more satisfied with their salary than those with religion. 2. CHPs who hoped for continuous education showed higher scores than the others on necessary job, professional pride and autonomy. Those who chose for independent job showed higher scores than the others on both necessary job and professional pride. Those who hope for long duration showed higher scores than the others on both necessary job and professional pride. Those who were satisfied with the present occupation showed higher scores than the others on pay satisfaction, necessary job, professional pride, interaction, autonomy and demand from organization. 3. Their autonomy scores differed significantly according to work status, both interaction and autonomy scores did so according to the fields of the past job in CHP, and their autonomy scores according to location of clinics. Their interaction scores differed significantly according to the frequency of home visits per mouth, both the degrees of salary satisfaction and professional pride scores did so according to the frequency of counseling education per mouth, and their professional pride scores did so according to total income per year. 4. The levels of their responsibility and self-confidence showed the highest of all personality traits variables. 5. The professional pride score of CHPs showed the highest of all job satisfaction variables. 6. Dominance were mostly correlated with autonomy and responsibility were mostly associated with professional pride. Both emotional stability and self-confidence were mostly related necessary job. In conclusion, religion, location of clinics, clinical experience, opportunity for education, dominance, self-confidence, the duration of services hoped for, satisfaction with the present occupation, the field of past job and administrative affairs were found to be the important factors in the degrees of their job satisfaction. Therefore, the methods to consider these variables will be necessary to develop for enhancing the efficiency of their Job performance and the degrees of job satisfaction.

For the study of morphological variation of Q. variabilis natural population in Korea, 19 populations were selected through the country in considering latitude, longitude, and geographical characters. Thirty trees were randomly selected from each population and 60 mature leaves were sampled from each tree. Four characters (leaf blade length, maximum blade width, petiole length, and vein number) were measured, and their ratios (the ratio of blade length to maximum blade width, the ratio of blade length to petiole length, the ratio of petiole length to vein number, upper 1/3 blade width to maximum blade width, and upper 1/3 blade width to lower 1/3 blade width) were calculated. 1. Analysis of variance for all leaf characters were significantly different among populations and among individuals within population. Contributions of variance among individuals within population in all the characters were higher than those among populations. Therefore, selection of plus trees may be preferable to desirable populations for breeding program of Q. variabilis. 2. Among principal component analysis for leaf characters, primary 2 principal components appeared to be major variables for leaf form of Q. variabilis because of the loading contribution of 80.5%. The first contribution component was petiole length/vein number and petiole length ; the second one was upper 1/3 blade width/maximum blade width, upper blade width/lower 1/3 blade width and vein number, respectively. 3. Latitude was positively correlated with blade length/maximum blade width and blade length/petiole length, but negatively correlated with petiole length/vein number, upper 1/3 blade width/maximum blade width, upper 1/3 blade width/lower 1/3 blade width, petiole length, and vein number. But, for longitude and altitude the former two traits and the later five traits exhibited the negative and positive correlation, respectively. 4. Cluster analysis using complete linkage method for leaf characters showed two groups to Euclidean distance 1.6. They were group I of population 1. 4, 5, and 13 and group II of population 2, 3, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 18, and 19. However, group II was divided again to Euclidean distance 1.3, that is a group including population 3, 7, 10, 14, 15, and 17(group II-1) and the other group comprising population 2, 6, 8, 9, 11, 12, 16, 18, and 19(group II-2). This cluster could be mainly observed due to difference among population in aspect (group I : NE, group II-1 : SE, and group II-2 : SW).

The purpose of this study was to analyze the relationship between sanitary knowledge score and sanitary management performance among school foodservice employees. For this purpose, a paper-based questionnaire was developed and distributed to 300 school foodservice employees in Jinhae-gu, Changwon from May 13 to June 10 in 2009. A total of 276 responses were received and analyzed. The results of this study were as follows. The sanitary knowledge score of school foodservice employees was 16.60 (total score: 20). Their sanitary management performance level was 4.77 (based on a 5-point Likert scale). We found that sanitary management performance level of high sanitary knowledge score group was significantly higher than that of low sanitary knowledge score group (P<0.001). There was a significant positive correlation between sanitary knowledge score and sanitary management performance of school foodservice employees (P<0.01). Regression analysis showed that sanitary knowledge score of school foodservice employees had a positive effect on sanitary management performance (P<0.001). It implies that as school foodservice employees' sanitary knowledge increased, their sanitary management performance increased. In conclusion, to improve the sanitary quality of school foodservice, school foodservice employees' sanitary management performance level should be increased by improving their sanitary knowledge. So, a systematic and consistent sanitary education program should be conducted for school foodservice employees.

This study was performed to investigate the escape of pine wood nematode (PWN), Bursaphelenchus xylophilus, from two vector species (Monochamus alternatus and M. saltuarius) through oviposition and feeding behavior. First, we checked number of PWNs escaped from M. alternatus emerged from three different cases of pine logs. In case A, healthy pine trees were cut into logs and left in pine forest infected with PWN. In case B, healthy pine trees were cut into logs, left in large screen cage, and let them oviposited by M. alternatus emerged from pine trees infested with PWN. In case C, pine trees which were harboring M. alternatus were cut into logs, and PWN was inoculated artificially. The M. alternatus adults emerged from the above three cases of pine logs were checked in the next year to know how many PWN they were harboring in their bodies. The percentages of M. alternatus harboring PWN (18.3 and 15.6%, respectively) and number of nematodes per vector ($5,713.1{\pm}9,248.3$ and $2,034.1{\pm}4,746.8$ PWNs, respectively) in case A and B logs are similar to each other. However, the percentage and the number in case C (38.3% and $20,083.1{\pm}32,188.3$ PWNs) were higher than those of case A and B. Among 52 M. alternatus adults harboring PWN from all the three cases, 20 adults (38.5%) were harboring more than 5,000 PWNs per beetle. And these 20 adults were harboring 97.9% of the total PWNs in 52 adults. Second, we checked the daily escape of PWNs from M. alternatus and M. saltuarius collected at pine forest infested with PWN. The PWN escaped from their vector body for $34.9{\pm}12.4$ days for M. alternatus, and for $23.9{\pm}16.2$ days for M. saltuarius, reaching at peak escape during the 2nd week of emergence of the two vector species. A 44.5 and 47.2% to the total PWNs escaped from vector body within 2 weeks of vector emergence for M. alternatus and M. saltuarius, respectively. The number of PWNs escaped from each vector was $3,570.6{\pm}5,189.2$ and $1,556.2{\pm}1,710.3$ for M. alternatus and M. saltuarius, respectively.

Purpose: To determine the appropriate prostate planning target volume (PTV) margins for 3-dimensitional (3D) conformal radiotherapy (CRT) and intensity-modulated radiation therapy (IMRT) patients treated with an endorectal balloon (ERB) under our institutional treatment condition. Materials and Methods: Patients were treated in the supine position. An ERB was inserted into the rectum with 70 cc air prior to planning a CT scan and then each treatment fraction. Electronic portal images (EPIs) and digital reconstructed radiographs (DRR) of planning CT images were used to evaluate inter-fractional patient's setup and ERB errors. To register both image sets, we developed an in-house program written in visual $C^{++}$. A new method to determine prostate PTV margins with an ERB was developed by using the common method. Results: The mean value of patient setup errors was within 1 mm in all directions. The ERB inter-fractional errors in the superior-inferior (SI) and anterior-posterior (AP) directions were larger than in the left-right (LR) direction. The calculated 1D symmetric PTV margins were 3.0 mm, 8.2 mm, and 8.5 mm for 3D CRT and 4.1 mm, 7.9 mm, and 10.3 mm for IMRT in LR, SI, and AP, respectively according to the new method including ERB random errors. Conclusion: The ERB random error contributes to the deformation of the prostate, which affects the original treatment planning. Thus, a new PTV margin method includes dose blurring effects of ERB. The correction of ERB systematic error is a prerequisite since the new method only accounts for ERB random error.

The purpose of this study is to find out methods to control, regulate and prevent sexual violence and provide guidelines for sex education in middle school. This study was conducted to examine factors in relation to sexuality, attitudes toward women, experience of sexual contact, frequencies and kinds of pornography with which they had contact, and sex education. For the data collection, a survey was conducted from September 25 to October 1, 1997 by using prepared questionnaires. Questionnaires were given to 503 students from three different kinds of middle schools in Seoul, Boys, Girls, and Coeducation schools. The data analyses used a PC-SAS. Each item was examined by frequencies and percentage. To compare Boys with Girls, I applied a T-test. In addition, with the kinds of school type, I applied anANOVA, ${\chi}^2$. Moreover, For investigating and analyzing each category, I categorized knowledge and attitude of sexuality, with precautionary measures of sexual violence. After that I applied T-test, ANOVA, and a Pearson's correlation for each category. The instruments of this study consisted of 9 domains. (1) General characteristics of the respondents (2) 9 questions about the interaction between he/she and his/her parent. (3) 12 questions, concerning A Scale for Attitudes of Adolescents Toward women(AWSA). (4) 26 questions related to sexual knowledge. (5) 25 questions about sexual attitude (6) strategies for prevention of sexual violence-33 questions (7) 5 questions related to sexual behavior (8) the experience of contact with pronography. (9) the experience of sex-education. The major results were summarized as follows; 1. Like many researches, This study shows that the girls are more eqalitarian than boys. The girls mean ($40.90{\pm}3.67$) is significantly higher than boys ($34.72{\pm}3.77$). Most Koreans have believed that there are many differences between men's roles and women's ones, because of confucianism which had been implied in most thought and ideas since the Lee dynasty. Therefore, the result is not surprising at all. 2. Most students answered correctly the questions of sexual knowledge. The girl's score was higher ($Mean{\pm}SD$ : $48.88{\pm}2.39$) than the boys' ($Mean{\pm}SD$ : $46.95{\pm}3.90$)(p 0.001). Nevertheless, the hypothesis that sexual knowledge influences sexual attitude and its behavior was rejected. 3. When twenty-five questions were asked about sexual attitude, the girl students investigated were found to have a more propre sexual attitude than that of the boys. A significant difference was found between boys and girls(p=0.001). The result shows that a person who has more experience in viewing pornography and who smokes will have a more distorted view of sexuality. 4. There are many students who have experienced of sexual contact. They need to take a sex education program about contraception and prevention of sexually transmitted diseases. Systematic and concrete sex education is one way to lead them to proper sexual behavior. 5. Most respondents rejected stereotyped attitudes towards women. Boys, however, were more likely to accept stereotypes of Women. The girl's mean($Mean{\pm}SD$ : $40.90{\pm}3.67$) is higher than the boys($Mean{\pm}SD$ : $34.72{\pm}3.77$)(p=0.0001). 6. Many boys ignored the rules for prevention of sexual violence. A boy or a girl who has more experience of sexual contact over kiss and sex-typed neglected the rules, too(p=0.001). Today, there is increasing juvenile delinquency related to sexuality. This study provided the basic material for a preventive education system. I believe that a systematic and concrete sex education system can be helpful for adolescents and promote their responsibility as well as cultivate morality about sexuality. As a result, juvenile delinquency can be decreased. This study is basically aimed to provide information for a prevenative education system of sexual violence. Further research is recommended to evaluate programs in schools.

The purpose of this study was to evaluate the effect of systemic oral health education on the improvement of knowledge levels and patient hygiene performance(PHP) for elementary school students. The randomly selected 1st and 5th grade students in a public elementary school of Taegu city were divided by education group(118 students) and non-education group(122 students). The oral health education lesson was systematically held on the education group once a month for 4 months. The questionnaire queried all the subjects about their knowledge and attitudes before and after oral health education, and PHP was also tested at the same time. Corresponding p-values were significantly considered at values less than 0.05. The obtained results were as follows: Due to the oral health education lesson, the education group of both 1st and 5th grade students came to have a higher knowledge level than the non-education group. There was high improvement of items such as toothbrushing time, toothbrushing method, cause of dental caries, treatment after tooth damage, and tongue-brushing. Therefore, these items should be educated to all the elementary school students. By increaseing the knowledge level of oral health after education, the PHP index in the education group was significantly decreased in comparison to the non-education group and hence the capability of oral health management improved. From the above results, a systematically and periodically oral health education system for elementary school students can improve the knowledge level and capability of oral health management. Further study will be required to develop an easy and acceptable systemic oral health education program for elementary schools.

Objectives: This study was conducted to analyze the dental care utilization patterns and related factors of the rural residents. Methods: The data collected by interview and self-administered questionnaire survey of 524 peoples of Seongju county in Gyeongsanbuk-do. The summarized results are as follows. Results: The rate of persons who experienced the oral disease was 52.5% during 1 year and it was at most in the age group of 40-49. The rate of persons who had experienced the oral disease were investigated according to general characteristics, perception of oral health, being of regular treatment facility. Therefore the rate of persons who had experienced the oral disease was significantly higher the younger peoples, worse oral health status and being of the regular treatment source than the other groups. During 1 year period, 64.0% of the cases had treated the perceived oral disease, 36.0% did no action at all during last year. Among respondents, 49.4% had treated their oral disease at dental clinics, 8.0% had treated at community health center or subcenter and remains did not treated at all. The results of logistic regression analysis suggested that statistically significant factors in dental health care utilization were educational level, degree of pain, oral health status and regular treatment facility. Therefore the dental health care utilization rate was higher at groups with the high educational level, serious pain, better oral health status and being of the regular treatment source than other groups. 45.5% of the rural residents did not treat their oral disease immediately due to the no identified need, limitation of time(19.2%), economic limitation(19.2%), and geographical limitation(9.0%). Conclusions: In consideration of above findings, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically.
