Objectives: This study was conducted to examine the educational needs of elderly hypertensive or diabetes patients and educators for the education program development of cardiocerebrovascular high-risk group in community. Methods: This study was conducted with 60 hypertensive or diabetes patients aged 65 years or above (cardiocerebrovascular high-risk group) who had registered KHyDDI(Korea Hypertension Diabetes Daegu Initiative) Project and attended Hypertension Diabetes Intervention Center Program, and with 44 educators in the center between June and August, 2009. Data were collected using questionnaires including general characteristics, educational objectives, curriculum, contents, and methods. Results: The major findings of this study were as follows: In education methods, cardiocerebrovascular high-risk group and educators both preferred small-grouped(5-9 persons) or individual education, 30min-1 hour, 50%-50% of theory-practice ratio, 3 months of education. In education contents, both groups needed all the suggested contents. Five categories would be suggested for the development of education program. The first category was that there was no significant difference between cardiocerebrovascular high-risk group's needs and knowledge. The second was category of low knowledge level in cardiocerebrovascular high-risk group's knowledge. The repeated education would be necessary for this category. The third was category with large standard deviation in cardiocerebrovascular high-risk group's knowledge. Individual education would be necessary for this category. The fourth category was that there was significant difference between cardiocerebrovascular high-risk group's knowledge and knowledge assessed by educators. The improvement of educator's education skill would be necessary for this category. The fifth category was that there was significant difference between cardiocerebrovascular high-risk group and educator's needs. Conclusions: Small group or individualized and staged education reflecting above cardiocerebrovascular high risk group and educators' needs should be developed for more effective education to prevent and manage the cardiocerebrovascular disease.

Summary : This study was designed to identify the difference in temperament, parent-adolescent's goodness of fit and behavioral problems between early-adolescent high risk group which can be divided into subgroups (ADHD-I and ADHD-HI/C) and normal group. Method : Subjects of this study were students of a Boy's Middle School and their parents. ADHD high risk group was determined by using three rating scales of ADHD behavioral symptoms : 1. Korean-ADHD Rating Scale, 2. Abbreviated Conners Parents Rating Scale, 3. Conners-Wells' Adolescent Self-Report Scale. Final research was based on the subjects including 25 people in ADHD-I high risk group, 70 ADHD-HI/C high risk group, 70 in normal group. Revised Dimensions of Temperament (DOTS-R) was used for students to assess their temperament, while DOTS-R : Ethnology for parents to access environmental demands. Goodness of fit between parent and adolescent was figured out by results of the two scales. Korean Youth Self Report (K-YSR) was used to examine behavioral problems. Results : When it comes to temperament of adolescents, ADHD-HI/C high risk group was found to be associated with higher scores on general activity level. In contextual parent demand to adolescent, ADHD-HI/C parents showed higher level of demands in general activity than other groups, and lower expectation of positive mood than ADHD-I parents. In parent-adolescent's goodness/poorness of fit, the research found out that ADHD-I and ADHD-HI/C had lower level of fit on pesitive/negative mood than normal group and indicated that ADHD behavioral symptoms connected with poorness of fit in emotional relationship between adolescents and their parents. In behavioral problems, ADHD-HI/C high risk group had severe externalizing and internalizing problems distinctly. It had more severe in externalizing problems than ADHD-I, while there were no differences in internalizing problems between the two subgroups. Conclusion The two ADHD subgroups in high risk adolescents had differences on temperamental activity level and on goodness of fit about positive mood. In addition, they had different patterns in externalizing/internalizing problems.

This study was conducted on workers in high risk groups. And the effects of improper equipment wear on the recognition of safety accidents and job exhaustion. In addition, the mediating effect of the recognition of safety accident risk was identified. The results of the analysis are as follows. Because high-risk workers wear inappropriate equipment, emotions are depleted and personalization problems arise. And the mediating effect of the recognition of safety accident risk. Therefore, there is a need to provide generous support to ensure that high-risk workers are able to work properly in hazardous workplaces, so that they can wear appropriate equipment to defend the risks.

Objective: This study was conducted to evaluate an education program for cardiocerebrovascular high-risk patients. Methods: This program was developed according to Tyler's model for curriculum development. To evaluate the effects of this program, we measured clinical outcome change (weight, waist circumference, systolic blood pressure, diastolic blood pressure) and behavior change stages (checking blood pressure, blood sugar levels, doing physical activity, consistent maintenance of food intake, eating low amounts of salt, abstention from tobacco and alcohol) before and 4 weeks after participation in the education program. The group of subjects consisted of High-risk group patients who attended basic program(32 patients), and staged program(37 patients) during KHyDDI meetings from Oct. 2009 to May 2010. Results: The staged educational program was developed three aspects(disease, nutrition and exercise)and three stages(basic, in-depth and individual education). In the staged education program, the evaluations were made by measuring clinical outcome and stage of behavior before and after education. Significant differences were found in waist circumference, systolic blood pressure, diastolic blood pressure, consistent maintenance of food intake(p<0.05), and eating low salt(p<0.001)and their self efficacy. Conclusion: In the practice-oriented staged education program, significant differences were found in the clinical outcomes and stage of behavior before and after education. Possible limitations of the study include the small number of participating subjects and the short follow-up management period, but the results indicate that continued application of this program could contribute to the prevention of cardiocerebrovascular diseases for the elderly patients with long periods of chronic diseases.

유두상 갑상선암의 대부분은 서서히 진행하는 양호한 임상경과를 보이나, 일부는 저등급 혹은 미분화 갑상선암으로 전환되는 생물학적 특성을 보인다. 저자는 유두상 갑상선암 환자 358예를 적용된 치료방법과 치료결과를 분석하여 논란이 되고 있는 치료방법들 중에서 적절한 치료방법을 찾고자 본 연구를 시도하였다.% 568예중 동측엽절제술 및 협부 절제술 혹은 갑상선 아전 절제술 220예, 갑상선 전 절제술 혹은 근전절제술 143예, 종양적출술 5예였고, 이중 115예는 여러가지 형태의 경부 곽청술이 추가되었고, 150예는 수술후 방사성 동위원소 치료까지 추가되었다. 또 전 환자에서 TSH 억제를 위한 갑상선 호르몬 투여를 하였다. 추적 기간은 5년에서 12년까지 평균 8.5년이었다. Cady와 Rossia AMES Scoring system에 따라 저위험군과 고위험군으로 나누어 재발율과 사망율을 산출한 결과 저위험군 255예중 재발율 11.0%, 사망율 0.4%, 고위험군 65예중 재발율 36.9%, 사망율 20.0%을 보여 고위험군에서 현격히 불량한 예후를 나타내었다. 따라서 저자들은 유두상 갑상선암의 치료방법 선택은 일률적인 치료방법 보다는 환자 개인의 임상적 특성, 병기 등을 고려하여 저위험군에서는 소극적 수술을, 고위험군에서는 적극적인 수술과 수술후 보조치료를 시행하는 것이 바람직하다고 사료되었다.

The purpose of this study was to examine the possibility of the existence of high-risk groups of dental caries and influential factors for the high-risk groups, as there was a possibility that certain people might especially be at risk of suffering from dental caries when decayed, missing, and filled teeth index were analyzed, which were the typical indicators of dental caries. The data of the 4th National Health & Nutrition Survey for 2007, 2008 and 2009 were analyzed. Significant caries index (SiC index) were calculated, which were one of the representative devices to indicate high-risk groups of dental caries, and the SiC index and related factors were analyzed by using $x^2$ (chi-square) test. Besides, logistic regression analysis was utilized to find out influential factors, and a statistical package STATA 11.0 was employed. As a result of analyzing what factors would be linked to high-risk groups of dental caries, it's found that women were more likely to belong to high-risk groups than men (p<0.01). How the related factors affected the high-risk groups was analyzed, and it's found that those who didn't find themselves to be in good oral health were more likely to be classified into a high-risk group, and that those who brushed their teeth three times a more a day on a regular basis were more likely to belong to a high-risk group than the others who didn't (p<0.01). Thus, SiC index were calculated in this study to confirm the existence of dental caries high-risk groups, and what factors impacted on the high-risk groups was ascertained. It's required to implement efficient national policies to step up the promotion of national oral health based on the findings of the study.

Purpose : After Acquired Immunodeficiency Syndrome (AIDS) is known to be a fatal disease, efforts and studies are made to determine the cause, treatment method and method of preventing infection. However, no treatment method is present and vaccine development has not been made. Therefore, the most effective treatment method is prevention, and almost 100% prevention is possible when correct preventive measures are taken. We suggest effective prevention education by comparing knowledge and attitude of those unmarried men who had sexual encounters with prostitutes (high risk group) and those with no sexual encounters with prostitutes (low risk group). Methods : From January 1, 2000 to June 30, 2000, a survey was done in 516 unmarried soldiers and college students. With the collected data, chi-square test was used to compare and analyze the demographic characteristic, knowledge on AIDS, and attitude on AIDS between the high risk group and low risk group. One-way ANOVA test was used to compare and analyze the scores on knowledge between these two groups. Results : Among 516 unmarried men, 256 men (49.6%) fell into the high risk group and 260 men (50.4%) into the low risk group. Both groups showed that they heard of AIDS during their middle school years. The main route of obtaining knowledge on AIDS was through TV programs with 124 men(48.4%) in the high risk group and 167 men (64.2%) in the low risk group (P=0.002). Among 20 items, the average score on knowledge was $13.9{\pm}1.9$ in the high risk group and $14.1{\pm}1.8$ in the low risk group with no statistical difference between these two groups (P=0.191). Two items showed statistical significance in the low risk group compared with the high risk group; these were the item of AIDS being transmitted through transfusion (P=0.014) and through mosquitoes (P=0.009). As for attitude, statistical significance was present in the item stating that AIDS patients should be isolated in the high risk group compared with the low risk group (P=0.029). Conclusions : The present study showed that both the high risk group and low risk group obtained knowledge on AIDS through TV. No statistical difference was present between the two groups other than the high risk group showed statistically high results in two items on knowledge and one item on attitude. Thus, these results showed that exposure to AIDS can be lowered with better knowledge and the attitude of those with a low risk of infection was more positive.
