최근에 청소년과 청년층에서 항체 보유율이 낮아 A형 간염이 집중적으로 발생하고 있다. 또한 이들 연령층은 단체생활을 포함한 활발한 사회 활동으로 인해 HAV에 대한 노출 기회가 많아지게 되는데, HAV 감수성자 비율의 증가는 향후 A형 간염 발생이 더욱 폭발적으로 증가할 것으로 전망된다. 따라서 A형 간염예방 접종을 현재의 권장 접종방법을 조속한 시일 내에 12개월 이후의 모든 소아에게 접종하는 기본 접종으로 접종 방법을 바꾸어야 할 것으로 판단된다.

Objectives: We examined the trends in prevalence, awareness, treatment, and control of hypertension in Korea as a basis for improving hypertension control programs. Methods: 12 598 participants of the Korean National Health and Nutrition Examination Survey were included in this study. Weighted linear regression to test time trends from 2007 to 2011 was performed. Results: The prevalence of hypertension was 20.7% in 2007, 29.4% in 2009, and 26.2% in 2011. Awareness of hypertension was 64.8% in 2007 and 61.1% in 2011. Awareness in those aged 65 and over was greater than in younger groups (age 19 to 44 and 45 to 64; p<0.001). The treatment rates were 58.4% in 2007 and 56.8% in 2011. The treatment rate was greater for those 65 and over than for younger age groups (p<0.001). The percentage of controlled hypertension was 37.6% in 2011. The percentage of controlled hypertension in those 65 and over was higher than in younger age groups (p<0.001). The treatment-control rates were 65.9% in 2007 and 67.7% in 2011. The prevalence of hypertension was higher in the males (p<0.001), while the awareness (p<0.001), treatment (p<0.001), and control (p<0.001) rates were higher in the females. Conclusions: The prevalence of hypertension was increasing and the hypertension awareness, treatment, and control rates were low in younger age groups and males.

본 연구는 한국의 청소년을 대상으로 외안부의 구조를 조사하였다. 그 결과는 다음과 같다. 1. 내안각간의 거리에서 평균 길이는 38-40mm이나, 남성이 여성에 비해서 길다. 2 검열의 길이에서 평균은 35-37mm이며, 우안과 좌안의 결과는 비슷하였다. 그러나 남성은 여성에 비해서 길게 되었다. 3. 검열의 폭에 대해서 평균 폭은 7-8mm이며, 남성과 여성의 결과는 비슷하였다. 4. 근거리에서의 동공간 거리는 평균 29-33mm이었으나, 20대에서는 남성의 좌안은 우안에 비해서 길다. 한편 여성은 그 결과가 반대로 된다. 5. 원거리에서의 PD는 평균 31-32mm 이다. 그러나 10대에서는 남성과 여성은 비슷한 결과를 가진다. 한편 남성은 여성에 비해서 길다.

Purpose: This study investigates nurses' organizational commitment, internal marketing, and occupational satisfaction depending on their age, martial status, clinical experience and income. Methods: The subjects of this study were 350 nurses from six hospitals in Jeolla-do. The t-tests were used to analyze the differences in internal marketing, occupational satisfaction, and organizational commitment depending on their age, marital status, career, and income. The relationships among internal marketing, occupational satisfaction, and organizational commitment were analyzed by the path analysis. Results: The results of this study showed that organizational commitment was correlated with age, clinical experiences, and income, but not significantly associated with martial status. Education and training policy, benefit system, and fairness of the internal marketing were influencing factors on occupational satisfaction. These factors were correlated with organizational commitment through occupational satisfaction. Conclusion: This study addressed the relationships among nurses' internal marketing, occupational satisfaction, and organizational commitment. Based on the results, it is suggested that hospital organizations introduce more diverse incentive policies to enhance nurses' occupational satisfaction and organizational commitment.

Purpose: The purpose of this study was to identify the factors of child behavioral problems and construct a descriptive model that explains child behavioral problems for school age children. Method: The participants in the study were 586 4th, 5th, 6th graders and their mothers. The children attended 8 elementary schools located in Taejon city and their mothers. The tools used in this study was the Mother's Child Raising Behavior Scale by Park, Seong-Yeon and Yi, Sook(1990). To measure child's self esteem, the Self Esteem Scale by Kim(1987) was used; child perceived social support was measured with the Social Support Evaluation Scale by Dubow and Ullman(1989), and childhood behavioral problems were measured with the Korean standardized of version of the Korean-Child Behavior Checklist(K-CBCL)(1997). Descriptive statistics and linear structural relationship(LISREL) modeling were used to analyze the data. SAS and LISREL 8.12a programs were used. Results: The overall fit of the hypothetical model to the data was good $>X^2=103.07(p=0.00)$, GFI=0.96, AGFI=0.94, RMSR=0.04, RMSEA=0.07, NFI=0.94, NNFI=0.95< Maternal child raising behaviors(T=2.21) and child perceived social support(T=10.29) had a significant, direct effect on a child's self esteem. Maternal child raising behaviors(T=-3.87), and child self esteem(T=-2.04) and had a significant total effect on child behavioral problems. These variables accounted for 63% of the variance of the child behavioral problems in the school age children. Conclusion: These finding have provided support for maternal child raising behaviors, child perceived social support, and child self esteem as predictive variables of behavioral problems in school age children.

A limb-sparing operation has a definitive role in the treatment of osteosarcoma in the lower extremity of skeletally-immature patients. After a limb-sparing operation, leg length discrepancy remains as a major disability that should be corrected. This study was designed to suggest methods of tumor resection and proper timing of leg length equalization in skeletally immature osteosarcoma patients. From September 1990 to January 1998, we reviewed eight osteosarcoma patients in an immature skeletal age. There were 4 males and 4 females, and their mean duration of follow-up was 50.37 months (range : 25 to 88 months). Mean skeletal age was 8 years (range : 8 months to 11 years). The patients were classified according to the methods of tumor resection ; intercalary resection in 1 case, transepiphyseal resection in 1, intra-articular resection in 5, and extra-articular resection in 1. The results were as follows ; 1. The leg lengthening was begun when a patient's leg length discrepancy reached 4-5cm. 2. The age of final lengthening with permanent reconstruction was 14 years in males and 12 years in females (about 2 years before skeletal maturity). 3. When reconstruction was performed with a temporary spacer, the site of lengthening Was in the soft tissue, not in bone, and then a permanant reconstruction was done. 4. Reconstruction with a biologic spacer to preserve the joint function was a reasonable method for equalization of leg length. In conclusion, the appropriate choice of reconstructive method and the age at which to correct the leg length discrepancy in a skeletally-immature osteosarcoma patients are important factors for maintaining leg length at full maturity.

The purpose of this study was to observe the makeup behavior and cosmetics preference based on the segmented age group and fashion appearance interested group. The target consumers were women aged in their 20's. We distributed 443 questionnaires and conducted statistical analysis using SPSS program for the 400 reliable questionnaires. Statistical analyses included frequency, Chi-square test, t-test, ANOVA and cluster analysis(K-means). The results of this study were as follows: 1. There was a significant association between specific cosmetic items currently used and segmented age group. The age 24-29 had more basic makeup than color makeup, compared to the age 20-23 group. There was a statistical difference between the highly interested group and the lowly interested group in fashion and beauty. The group of highly interested in fashion and beauty considered trendy colors, while the group of lowly interested in fashion and beauty used their favorite color as an important factor in purchasing makeup products. 2. There was a significant difference in the preference of lip colors and textures, eye shadows textures, types of eye liner and types of foundation according to segmented age groups. 3. Those who sought 'sexy' images preferred red/wine/purple lipstick colors, and green/blue/violet eye shadow colors. They significantly preferred jell/liquid type eye liner and liquid type foundation. Those who sought 'pure' images preferred orange colors and glossy textures of lipsticks. Those who sought 'elegant' and 'intellectual' images preferred pearl type eye shadow.
