본 연구는 등대풀(Euphorbia helioscopia)의 생장 특성, 수분매개자 및 이들의 방문빈도를 알아보기 위해 통영지역에 서식하는 등대풀의 자연집단을 대상으로 수분실험을 수행하였다. 등대풀은 3월 초에 싹이 올라와 3월 중순부터 개화하여, 4월 중순까지 수분이 이루어졌으며, 4월초에서 5월초에 열매를 맺고, 5월말에서 6월초 사이에 지상부가 소멸하는 특징을 보여주는 대표적인 초봄 성장형 종이었다. 3월 중순 꽃이 피기 시작하면서 수분 매개자들의 방문이 증가하였으며, 조사기간 동안 파리목, 딱정벌레목, 벌목, 노린재목에 속하는 11 종의 곤충이 방문하고 있어 기존의 대극속 종들의 연구결과와도 잘 일치하고 있다. 특히, 이들 중 파리목에 속하는 종들이 가장 높은 방문 빈도를 보여주고 있어 등대풀에 있어 가장 효율적인 수분매개자로 생각된다. 기존 연구에서 대극속 식물 종 당 방문하는 곤충은 상당히 다양한 것으로 보고되고 있으나 본 연구결과 등대풀의 경우 11 종에 불과해 상당한 차이를 보여주고 있으며 이와 같은 차이가 지역 곤충상의 특성과 연관이 있는지 혹은 초봄형 식물의 일반적 특징인지 더 연구해 볼 필요가 있다. 등대풀의 주요 수분매개자인 파리목의 경우 오전 중에 가장 높은 방문 빈도를 보이다가 시간이 지남에 따라 점점 그 빈도가 감소하는 경향이 있어 기존의 경우와 유사한 결과로 파리목은 그 행동 특성상 이른 아침에 수분 활동을 주로 수행하며 외부온도의 변화와 방문빈도는 상관이 없는 것으로 생각된다. 그러나, 등대풀의 경우에는 배상화서의 수가 증가하는 3월 중순에서 4월 중순까지 방문하는 곤충의 수도 전반적으로 증가하다가 그 이후부터 점점 감소하는 경향을 보여주고 있어 화서의 수 증가와 방문자 수 사이에 상관관계가 있다는 기존 연구를 지지하고 있다.

Objectives： Oral health care program for the elementary school children (ESOHCP) should be met the first priority because dental caries are highly sensitive and prevalent among them. This study was performed to enhance the efficiency of ESOHCP, and their oral health promotion. Methods： The Subjects were 346 students (3rd grade 163, 6th grade 185) of one elementary school in Busan. Dental IQ and actual oral health status； the decayed, mixing and filling teeth were checked through questionnaire and oral health examination from April to June 2002. Dental IQ was presented out of one hundred, and data analysis was done using SAS (ver 8.1) program. Results： The students' cognitive level about the causative and preventive factor of dental caries was relatively high. However, the practical aspects of preventive behavior - tooth brushing； three times per day (20％), three minutes per time (22％), oral health examination； one time per three months (10％) left much to be desired. And, only 27％ of the subjects had experienced in school oral health education. The mean level of dental IQ was 79 out of 100, and 51 ％ and 42％ of them had the decayed and teeth with filling, respectively, with the rate of DMFT 82％, DT 43％, FT 57％. The level of dental IQ was higher in case of having his (her) own tooth brush (p＝0.072), standard tooth brushing (p<0.001) three times per day, post meal, three minutes per time, present experience of oral health examination (p<0.001) and dental clinic visit (p<0.001). The grade of caries was more serious in case of 6th grade (p＝0.059), an absence of his (her) own tooth brush (p＝ 0.090), present experience of oral health examination (p＝0.021), and an absence of regular dental clinic visit (p＝0.003). The frequency of oral health examination (γ＝ 0.620), tooth brushing； times per day (γ＝0.445), post meal (γ＝0.355), expending times per brushing (γ＝0.352), right cognition to the treatment of caries (γ＝0.401), positive attitude to dental treatment (γ＝0.387), the frequency of dental clinic visit for the past one year (γ＝0.152) showed significant correlation with dental IQ. In the multivariate analysis, dental IQ was influenced by the frequency of oral health examination, right cognition to the cause of caries, times of teeth brushing per day, right cognition to the treatment of caries, etc., with adjusted R2＝0.857. Conclusion： Though the students' cognitive level about the causative and preventive factor of dental caries was high, the practical aspects of preventive behavior left much to be desired. Ant the current ESOHCP considered to be still inefficient. However, frequent dental visits had apparent correlation with hish level of dental IQ. The specialized and practical program should be needed for the efficient ESOHCP. Harmonized effort from educational, health and dental society is essential.

The main purposes of this study were to assess coffee shop use and to identify the influence of physical environment of a coffee chop on customer behavioral intention. The survey was administered from April to May 2011, targeting twenties college students in Seoul, Gyeonggi Province. A total of 174 copies of the questionnaire were collected for the data analyses such as frequency test, descriptive analysis, chi-square analysis, reliability test, factor analysis, ANOVA, Duncan's multiple range test and multiple regression analysis using SPSS 17.0 program. The main results of this study were as follows: The number of visits was once or twice a week. Students went with their friends to the coffee shop. Most of the students answered that they visit the coffee shop at any time. The main purpose of visit was to have time to relax. The main source in choosing a coffee shop was recommendation from others. The main criterion for the selection of the coffee shop was atmosphere. Americano was a favorite drink. Coffee was drunk with a cake. Expenditure per visit was 3,000~5,000 won. The choice of the coffee shop was selected by the student. The factor analysis identified seven underlying dimensions of coffee shop physical environment perceptions (seating comfort, attractiveness, cleanliness, harmony, ambient condition, congestion, amenity) and one dimension of customer behavioral intention. Through multiple regression analyses, four determinants (attractiveness, cleanliness, amenity, ambient condition) were found to have the greatest impact on customer behavioral intention.

Purpose: Perforation of choledochal cyst (CC) is a relatively rare clinical presentation in pediatric populations and difficult to predict preoperatively. We assess the clinical implications by comparing clinical parameters based on a single-center experience between perforated and nonperforated CC to facilitate the appropriate management for future interventions. Methods: A total of 92 cases of CC in pediatric patients (aged <18 years) who received surgical management between January 2003 and December 2018 at a Pusan National University Children's Hospital were reviewed. After screening the clinical features of perforated cases, we compared the demographic findings, clinical characteristics, and some laboratory results between the perforated and nonperforated groups. Results: Perforated CC was identified in 8 patients (8.7%), and nonperforated CC in 84 patients (91.3%). Perforation can be classified into three categories: free perforation of cyst (3 cases), pinpoint perforation of cyst (2 cases), and necrotic change of cyst (3 cases). CC perforation occurred significantly more commonly in patients aged <24 months. Clinically, the perforated group showed significantly higher frequency of fever and higher C-reactive protein (CRP) level during the initial visit. Conclusion: Perforation is more likely to be suspected in patients aged <24 months presenting together with fever and high CRP level in the initial visit. It is also necessary to keep in mind that it indicates not only a possibility of complicated disease status regardless of its association with stones but also a difficulty of applying a minimal invasive procedure and relatively increased length of hospital stay.

Purpose: The first-line treatment of temporomandibular joint disorders (TMDs) should include self-management and education. Self-management techniques include moist heat application, stretching, diet control, and mandibular rest position adjustment. Although the effectiveness of video educational resources has been studied in multiple sectors, their application in TMD management has not yet been explored. This study seeks to assess how effective media education was at motivating TMD patients to self-management and improve symptoms. Methods: Data were obtained from the hospital records of TMD patients who visited the Department of Oral Medicine, Yonsei University Dental Hospital, between May 2020 and December 2021. First, without any differences between groups, a significance analysis was conducted between the degree of self-management and symptom improvement over time. At the second visit, one group received media education (n=31) linked to TMD management, while the other received written-oriented education (n=45). At the third visit, the number of precautions taken by the patients was determined and contrasted to that recorded in the previous visit between the groups. Generalized estimated equation multivariate models were applied for statistical analysis. Results: In the media education group, the frequency of stretching and the number of patients on pain-free diets increased substantially. Taking precautions improved daily pain intensity, maximum mouth opening, and pain intensity during the maximum unassisted opening. Conclusions: Media education could be beneficial for TMD patients because it allows them to take self-management precautions. The symptoms of the media education group improved, with no considerable distinction between both groups.

The purpose of this study is to compare the satisfaction of the urban parks and to classify and assess the environmentally-friendly behaviors in the urban parks. For this purpose, the park user's behaviors and satisfactions were surveyed in 10 parks in Seoul and its suburb area. Parks are divided into 2 types, the walking-distance parks and the metropolitan parks, by time to reach, visit frequency and visit purpose. The park users are generally satisfied with the facilities, but not satisfied with some specific items, such as cultural facilities, accommodations for the handicapped, safety facilities and sports facilities. The environmentally-friendly behaviors are positively assessed in general, but the behavior of the natural experience was negatively assessed. The environmentally-friendly behaviors in the urban parks are classified into 2 factors; the experience factor and the activity factor. The parks are categorized into 3 types by these factors. For type I parks, the experience factor is dominant, but the activity factor is relatively low. For type II parks, the both factors are low and the parks are necessary to improve. And type III parks are positively assessed in the aspect of the environmentally-friendly behaviors, even though some park are necessary to complement.
