Objectives : Because elementary school children are sensitive and prevalent to dental caries, oral health care program for the elementary school children (ESOHCP) should be met the first priority for the national oral health care program. This study was performed to proposed the guidelines for executing the efficient ESOHCP through the evaluation of present oral health care and education status based on the attitudes and opinions of health teachers. Methods : Subjects were 181 health teachers those are a part of the total 273 elementary school health teachers in Busan. From April to June 2001, questionnaire survey on the teacher's attitude and opinion, present status of oral health care and education in their own school was done. Data was analyzed by $\chi^2$-test, t-test, ANOVA using SAS (ver 6.21) program. Results : Mean age of the teachers was 40 years (24~58 years) and mean scale of the subject school was 32 classes (5~58 classes). Above 90% of them agreed with the necessity and importance of ESOHCP, but actual level of concerning was lower. They gained the informations about oral health mainly from media (33%), PC net (26%), academic society (25%), and more used internet (p=0.012) in younger generation. Though most of them (96%) had a specified school dentist, only 58% had the experience of periodic oral health examinations in their own school. The major experienced ESOHCP was fluoride brushing and contest to choose the best healthy teeth. Oral health education given by the teachers was not professional but their own. About half (42%) of the teachers had never taken education during last one year. Major education materials were VTR tape (79%), teeth model (64%), CD (55%), booklet (50%), etc., and the teachers' preference was also VTR tape (43%) and CD (41%). When they need education materials, they frequently request to dentist's association (36%), academic society (35%), but rarely to dental clinics or dentists (6%). They prefer that two times (46%) of annual oral health education, with the contents of regular brushing (53%), but lower regular visit to clinics (13%). The interest to oral health care (p=0.016) increased with teacher's age. And, they agreed regular students education in case of higher interest(p=0.044). Intention about join in the model school program was decreased with scale of school (p=0.002). Conclusions : This result showed that the present status of ESOHCP is still insufficient. It considered that the health teachers' interest and role is most important for the maintenance and success of ESOHCP. The professional and efficient education program would be focused on the health teachers to induce drive on ESOHCP.

Objectives : Many studies have shown an association between serum lipid concentrations and psychologic characteristics. However, conflicting results have also been reported. This study was designed to find the relationship between serum lipid levels(cholesterol and triglycerides) and psychologic characteristics(impulsiveness, aggressiveness, depressiveness) in adolescents. Methods : Serum cholesterol concentration, serum triglycerides concentration, complete blood count, electrolytes, liver function test, and blood sugar level were measured by overnight fasting blood sampling and urinalysis was also conducted in 407 high school students. Impulsiveness level was measured by Barratt Impulsiveness Scale(BIS). Aggressiveness level was measured by Buss-Durkee Hostility Inventory(BDHI). Depressiveness level was measured by Beck Depression Inventory(BDI). Serum cholesterol was measured by standard enzymatic assay and serum triglycerides was measured by Boehringer Mannheim method. Results : 1) Low cholesterol group(<15 percentile) were found to have significantly higher BIS score than high cholesterol group(>85 percentile) in female. Female low cholesterol group were also found to have significantly higher motor impulsivity score, a subscale of BIS, than high cholesterol group. 2) High triglycerides group(>85 percentile) were found to have significantly higher BDI score than low triglycerides group(<15 percentile) in male and female separately. Especially, male high triglycerides group were also found to have significantly higher BIS and motor impulsivity score than low triglycerides group. Conclusion : These results support the previous hypothesis that serum lipid levels(cholesterol and triglycerides) affect human psychologic characteristics.

To investigate whether BF-7, extracted from Bombyx mori, improved learning and memory of ordinary people, K-WAIS (Korean version of Wechsler adult intelligence scale) was performed in 4 normal students. Treatment with 400 mg of BF-7 increased mean IQ from 103 to 114. To know how BF-7 plays such a positive role, we measured the blood flow to brain, especially for the area concerned with learning and memory, with Single Photon Emission Computed Tomography(SPECT). Our result showed that the blood flow to parahippocampal gyrus and medial temporal area was increased. Also, our results showed the image representing the increase of blood supply in this area. So, our results suggest that BF-7 effectively help to use brain concerning with learning and memory.

Object：The purpose of this study was to investigate frequency and risk factor of violence toward parents seen in adolescents. We also want to apply this data toward developing a prevention program for adolescent violence. Method：A total of 1,345 students from 5 middle schools in Seoul, participated in this study：675 males, 670 females. We administered self-reporting questionnaire including violence toward parents, exposure to violence, family history of alcoholism, substance abuse of adolescetnt and dermographic data etc. Result：The frequency of boys’ violence toward parent was 2.8%, which was significantly higher than girls’(p<0.001). The frequency of violence toward the father was higher than the mother. The risk factors for violence toward parents were sex, parental alcohol problem, adolescent alcohol-smoking-drug problem, exposure to violence at home in the last year and exposure to violence in the life(p<0.0001). The grade, punishment, socioeconomic status, educational level of parent were not significantly related to violence toward parents. Conclusion：These suggest that adolescent violence toward parents is not rare problem any more and preventive intervention is needed for high-risk groups, that is related with experience domestic violence, substance abuse, alcoholic parent.

Objectives : The purpose of this study was to analyze dental records performed through a dental hygiene process and provide basic data on clinical training education for dental hygienists. Methods : The dental hygiene records of 440 senior dental hygiene students in Y University from March 2005 to September 2008, were examined. The needs of the clients confirmed by the dental hygiene diagnosis was based on Human Need Theory. The client's needs and the number of visits were analyzed according to the general characteristics(gender, age). The contents of the dental hygiene implementation performed according to the needs were divided into dental hygiene care and oral health education. The dental hygiene evaluation was classified into 'Met of Goal', 'Partially Met of Goal', and 'Unmet of Goal' according to the dental hygiene diagnosis. Data analysis was performed for the Frequency statistics and a Fisher's exact test using SPSS 12.0K for Windows. Results : 1. The clients were mostly aged in their 20's(307 clients). 2. The dental hygiene care usually performed was 'Scaling' and 'Recommendation to visit a dental clinic', and the education performed was 'How to brush teeth'. The implementation result from the need to Freedom of Stress was as simple as 'Be careful when treating' and 'Explanation of medical treatment and tools'. 3. The dental hygiene evaluation showed a higher met rate in the field of education than in that of the dental hygiene care. The reason for unmet the goal was 'Lack of the client's efforts and they didn't visit dental clinic'. Conclusions : The search for a range of clients for dental hygiene process should be made through effective connections between the local community institutions and schools. It was suggested that they should be strength the practical exercises for clients suffering dental anxiety and stress in dental treatments. In addition, education and attempts to motivate the clients should be performed according to their characteristics.

This study was aimed to elucidate the changes in heart rate variability during treadmill exercise at various speeds and grades by spectral analysis. Thirty-three untrained male college students aged $20{\sim}26\;yr $were employed to exercise on a treadmill using 4 speeds (4.02, 5.47, 6.76 and 8.05 km/h) and 6 grades (0, 4, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The electrocardiogram, respiration and the stepping activity were continuously recorded through an A/D converter system on the computer disk. Power spectra of heart rate variability (RRV) were obtained by use of a fast Fourier transform algorithm. The frequency domain was divided into 3 bands: $VLF\;(0{\sim}0.04\;Hz),\;LF\;(0.04 {\sim}0.15\;Hz)\;and\;HF\;(0.15{\sim}1.00\;Hz).$ Heart rate was $74.4{\pm}2.1\;beats/min$ at rest and showed a steady increase during treadmill exercise with increasing speed and grade up to $196.7{\pm}5.0\;beats/min.$ Total power of HRV was $35.0{\pm}6.7\;(beats/min)^{2}$ at rest and progressively decreased during exercise down to $1.9{\pm}0.3\;(beats/min)^{2}.$ The %VLF power of HRV was $34.5{\pm}3.7\; %$ at rest and showed no significant change during exercise except for a decrease observed at the highest intensity of exercise. The %LF power was $44.1{\pm}3.0\;%$ at rest and showed a progressive decrease down to $4.5{\pm}1.0\;%$ during those stages of exercise where heart rate was over 135 beats/min. The %HF power was $21.4{\pm}2.9\;%$ at rest and showed a progressive increase up to $87.1{\pm}6.7\;%$ during higher intensity exercise where heart rate was over 165 beats/min. Peak frequency of HF band was $0.200{\pm}0.018\;Hz$ at rest and was shifted to higher frequencies up to $0.909{\pm}0.048\;Hz$ at heart rates greater than 135 beats/min. Respiratory frequency was $18.0{\pm}1.5$ breaths/min at rest and significantly increased during exercise up to $53.0{\pm}3.7$ breaths/min. Stride frequency during treadmill exercise showed an increasing tendency with increasing speed from $55.6{\pm}0.9$ steps/min at 4.02 km/h to $81.2{\pm}0.6$ at 8.05 km/h. It was concluded that total power of HRV decreased progressively with increasing exercise intensity due to the withdrawal of parasympathetic activity. At higher exercise intensity, % LF power decreased and %HF power increased with its peak frequency shifted to higher values in a progressive mode with increasing speed and grade, reflecting a readjustment in the cardiovascular system and the increased respiration and its rate, respectively.

The purpose of the study was to examine nonpsychiatric physicians' attitudes toward psychiatry. 129 physicians responded to the questionnaire regarding attitudes toward psychiatry. A majority were favorable about psychiatric education, psychiatric consultation, psychoanalysis, students' choice of psychiatry as a career, and psychiatrists. Staff were more positive toward psychiatry than residents, and senior staff were more positive about psychiatry than junior staff. Overall, however, no significant differences were found in attitudes toward psychiatry between nonsurgical physicians and surgeons, although staff or residents in nonsurgical departments were more favorable about some aspects of psychiatry than staff or residents in surgical departments. The physicians with more interest in psychiatry as a career in the past were more likely to to be positive about psychiatry as a comprehensive science and a rapidly expanding field of medicine. Physicians with older age were more likely to be positive about status and efficacy of psychiatry, role and functioning of psychiatrists than those with. younger age. The results suggest that previous interest in psychiatry, age and clinical experience favorably influenced physicians' attitude toward psychiatry. In addition, development of models for psychiatric education will be needed to enhance physicians' attitude toward psychiatry.

Purpose: The present study intended to reveal the association between the physique of adolescent women and dysmenorrhea, and the factors related to the frequency of dysmenorrhea. Methods: The study subjects included 511 girls of a women's high school in Daejeon city and they were, during the period of March 1st through April 30th, 2005, given self-administered questionnaires about frequency of menstruation, age, physique, exercise, and such menstruation-related items as age of menarche, menstrual period and days, and amount. Results: As with the frequency of dysmenorrhea, 38.4% experienced it 「always」, 44.6% 「occasionally」, and 17.0% 「almost scarcely」, and those with dysmenorrhea accounted for 83.0% of the subjects. The frequency of dysmenorrhea was not significant difference according to the BMI and HPI. However, the lower the age of menarche and the greater the amount of menstrual flow, the more frequent dysmenorrhea. The symptoms of dysmenorrhea included the highest frequency of low back pain(68.5%) and it was followed by abdominal pain(65.9%), sensibility(54.0%), fatigue(51.7%), and nervousness(49.5%). These accompanied symptoms tended to be worse as the frequency of dysmenorrhea increased. The multiple logistic regression analysis revealed that the relative risk of frequency of dysmenorrhea is 2.2 times in age of 14, by a standard age of 15 as menarchial age, 2.2 in 13, and 3.1 in below 12. The menstrual days was 3.0 times in both below 2 days and over 8 days with the standard days of 3-7 days. The menstrual amount was 1.9 times in the group with a greater amount of menstrual bleeding and 1.5 times in the group with a less amount than the normal group, respectively. Conclusion: The above results suggest that the rate of experiencing dysmenorrhea was up to 83.0% and 38.4% from these had dysmenorrhea upon every menstruation. It is thought that dysmenorrhea could be a great disadvantage sufficient to impair optimal health to a larger body of school girls. Further, for quality of life, it is required that more fundamental strategies instead of pain killers or others for palliation of dysmenorrhea would be established among adolescents.

Recently, nonsuicidal self-injury (NSSI) has been increasing considerably in school counseling. According to the Youth Counseling and Welfare Development Institute, the number of counseling support for NSSI adolescent in 2018 was more than three times higher than the previous year, and the average time when NSSI behavior first appeared was 12.43 years old. As such, adolesnect NSSI continues to increase in recent years, and the age is also gradually decreasing. Nevertheless, research on the motives and characteristics of NSSI among domestic adolescents is still insufficient. This may be attributed to the difficulty of conducting research because self-injury behavior is secretly performed. However, it is also true that this reality has another limitation in the school field, which urgently requires counseling intervention and prevention of students' mental health problems. In addition, counseling for self-injury in the school scene is the biggest cause of exhaustion for counselors because they are under very great stress to cope with repeated self-harm in the dual role of counselors and teachers in school situations. Therefore, this study examines the causes and characteristics of involuntary self-injury through previous research analysis, and examines various difficulties experienced as a school counselor, as well as the effective intervention method of non suicidal self-injury in school counseling.

Objectives：We developed a Korean version of the Brief Measure of Worry Severity(BMWS), and examined its reliability, validity, and factor structures. We also explored the associations of pathological worry with depression and anxiety. Methods：Three hundreds fifty-two subjects including community population and college students completed the BMWS, and 27 subjects repeated the scale three weeks later. Reliability was assessed by Cronbach's coefficient ${\alpha}$ and test-retest correlation. The external validity was examined by the correlation of the BMWS score with the scores of Beck Depression Inventory(BDI), Patient Health questionnaire-2(PHQ-2), State Anxiety Inven-tory(SAI), and Trait Anxiety Inventory(TAI). And principal component analysis was performed to evaluate the construct validity. The associations of pathological worry with depression and anxiety were explored using partial correlation analysis. Results：Cronbach's coefficient ${\alpha}$ for the BMWS was 0.904 and test-retest correlation was 0.56(P<0.01). The Spearman correlation coefficients of the BMWS score with the scores of BDI, PHQ-2, SAI, and TAI were 0.60(P<0.01), 0.42(P<0.01), 0.36(P<0.01), and 0.59(P<0.01), respectively. The BMWS showed unifactorial construct. When controlling for TAI score, the correlation coefficient between the BMWS score and the BDI score was 0.357(P<0.01), and when controlling for BDI score the correlation coefficient between the BMWS score and the TAI score was 0.446(P<0.01). Conclusion：The Korean version of the BMWS was found to be a reliable and valid questionnaire for measuring pathological worry. And we could identify the associations of the pathological worry with depression as well as anxiety.
