This study aims to investigate factors associated with turnover intention among public medical centers employees in capital areas. We surveyed employees who are working in public medical centers in capital areas, and 756 employees responded. Turnover intention was measured using a Lawler’s 4-item scale and multiple regression model was used. The results showed that the factors affecting turnover intention were age, education, occupational category, year of career, size of organization, and job stress. This study is meaningful in that it is the first to date which explores the turnover intention among public medical centers employees. Given that the Korean government is implementing various policies to strengthen roll of the public medical centers, these results can be used to make policies and strategies of human resources management in the public medical centers.

연구 계획: 한국인에서 우연히 발견된 무증상 흉추 측만증의 연령에 따른 유병률과 특성을 단순 흉부방사선 영상 분석을 통하여 확인하고자 하였다. 목적: 향후 흉추 측만증의 연구와 치료에 대한 기준을 정립하는 기초 자료를 제공하고자 하였다. 선행 연구문헌의 요약: 국내를 포함한 동양 인구에서의 흉추 측만증의 유병률을 조사한 논문은 현재까지 확인되지 않았다. 대상 및 방법: 2011년 8월 30일 부터 2012년 10월 31일까지 본 병원에서 단순 흉부 방사선 사진을 촬영을 시행했던 80세 미만 환자의 방사선 사진을 후향적으로 조사하였다. 흉추 측만증의 기준은 만곡의 첨부가 흉추부 내에 위치하고 Cobbs씨 방법에 의한 만곡각이 10° 이상으로 하였다. 촬영 당시의 연령을 기준으로 10세 미만(0-9세), 10대(10-19세), 20대(20-29세), 30대(30-39세), 40대(40-49세), 50대(50-59세), 60대(60-69세), 70대(70-79세)로 나누어연령군 간 흉추 측만증의 유병률과 만곡의 크기를 알아 보았고 남녀 및 좌우 만곡의 빈도, 주만곡 내의 척추 수, 첨부 척추의 위치, Nash & Moe 방법으로측정한 추체 회전, 그리고 골극 유무와 골극 형성 부위를 조사하였다. 또한 남녀간, 좌우 만곡간 만곡의 크기 차이를 함께 확인하였다. 결과: 총 26125명 중 흉추 측만증의 유병률은 2.4%(621명)이었고, 남성보다(1.8%, 246/13654), 여성에서(3.0%, 375/12471) 유병률이 더 높았다(p<0.001). 우측 만곡은 445명에서, 좌측 만곡은 176명에서 나타났다. 연령별 유병률 및 만곡각은 10세 미만에서 1.1%(14.2°±3.2°), 10대에서2.3%(17.4°±7.7°), 20대에서 2.5%(17.0°±8.9°), 30대에서 1.9%(15.8°±5.9°), 40대에서 1.3%(15.5°±6.6°), 50대에서 2.1%(18.0°±13.6°), 60대에서2.9%(14.3°±3.6°), 70대에서 6.1%(16.2°±4.8°)이었다. 흉추 측만증으로 진단된 환자의 평균 만곡각은 16.0°±7.0°였고 10-19°가 533명, 20-29°가 64 명, 30-39°가 11명, 40° 이상이 13명이었다. 성별에 따른 만곡각은 남성 15.4°±7.1°, 여성 16.8°±7.6°로 통계적으로 유의한 차이를 보였다. 결론: 한국인의 연령별 흉추 측만증의 유병률 및 특성을 확인하였으며, 향후 흉추 측만증의 연구와 치료에 대한 기준을 정립하는 기초 자료로의 활용을 기대한다. 제목: 한국인의 흉추측만증 유병률 Study Design: A cross-sectional study. Objectives: To provide reference data for the study and treatment of thoracic scoliosis. Summary of Literature Review: There have been no reports on the prevalence of thoracic scoliosis in Korea. Materials and Methods: From August 2011 to October 2012, radiographs of patients under 80 years of age who underwent routine chest radiographs were retrospectively reviewed. Based on their age when the chest radiographs were obtained, the patients were divided into 8 groups. The prevalence and angle of the curve of thoracic scoliosis were investigated in each age group, and the prevalence of thoracic scoliosis according to sex, the direction of the curve, number of vertebrae in the major curve, the location and rotation of the apical vertebrae, and osteophyte location were examined. Results: The prevalence of thoracic scoliosis was 2.4% (621 patients), and female patients (3.0%, 375 of 12471) showed a higher prevalence than male patients (1.8%, 246 of 13654) (p<0.001). Right curvature was present in 445 patients and left curvature in 176 patients. In each age group, the prevalence and degree of thoracic scoliosis were 1.1% (14.2°±3.2°), 2.3% (17.4°±7.7°), 2.5% (17.0°±8.9°), 1.9% (15.8°±5.9°), 1.3% (15.5°±6.6°), 2.1% (18.0°±13.6°), 2.9% (14.3°±3.6°), and 6.1% (16.2°±4.8°), respectively. The mean curvature in all scoliosis patients was 16.0°±7.0°. The angle of the curve was significantly different by sex (15.4°±7.1° for males, 16.8°±7.6° for females). The average curve angle of patients with thoracic scoliosis was 16.0°±7.0°, among whom it was 10°-20° in 533 patients, 20°- 30° in 64, 30°-40° in 11, and over 40° in 13. Conclusions: This study could be used as a reference point for the study and treatment of thoracic scoliosis. Key Words: Scoliosis, Thoracic vertebrae, Prevalence

죽염의 첨가 급여가 육계의 증체량, 도체성분 및 혈액성분에 미치는 영향

죽염은 우리나라에서 전래되어온 전통적 민간 의방의 하나로서 소화기 장애의 치료제로 사용되었다. 또한 염증, 당뇨, 순환기 질환, 바이러스성 질환 및 암 등 여러 가지 병의 치료에 효과적이라고 알려져 있다. 죽염은 여러 가지 광물질을 함유하고 있어 가축의 사육과정에서 생산성 향상에 영향을 미칠 것으로 사료된다. 따라서 본 시험은 3회 구운 생활죽염을 사료에 첨가 급여할 때 육계의 생산성에 미치는 영향을 규명하기 위하여 기초사료에 죽염을 0.1%, 0.2% 및 0.3% 수준으로 첨가 급여하여 육계의 증체량, 사료섭취량, 사료요구율, 도체성분 및 혈액 성분에 미치는 영향을 분석하고자 사양시험을 실시하였으며, 본 시험에서 얻어진 결과를 요약하면 다음과 같다. 육성전기에 생활죽염 첨가에 의한 증체량의 차이가 나타났으며 0.3% 첨가구인 T3구가 대조구에 비하여 9.6% 향상된 증체성적을 보였다. 사료요구율은 대조구에 비하여 죽염 0.3% 첨가구인 T3 처리구가 유의적으로 낮게 나타나, 약 2.6% 향상된 결과를 보였다(p<0.05). 또한 음수량과 분변 중 수분함량은 0.3% 죽염을 첨가 급여할 경우, 대조구에 비해 유의적(p<0.05)으로 증가하였으나, 닭가슴살의 일반성분, 복부지방함량 비율 및 혈액 성분은 죽염 첨가에 의한 유의적인 차이를 보이지 않았다. This study investigated the effect of bamboo salt (BS) on body gain, feed intake, meat composition, and blood characteristics of broiler chicks. BS was processed by roasting salt at 1,200∼1,300℃ in a bamboo container, with the open end plugged with red clay. In total, 120 broiler chicks were assigned to four treatments. Each treatment was triplicated, with 10 chicks in each treatment group. The supplementation levels of the three BS-treated feeds were 0.1, 0.2, and 0.3%. Body weight gain slightly increased in broiler chicks fed diets supplemented with BS compared to that of the control during the overall test period. However, no significant differences were observed among treatments. Feed intake was also not significantly different among treatments. Feed efficiency was significantly (p<0.05) improved in broiler chicks fed diets supplemented with BS compared to that of the control. Body weight gain was more positively affected by the dietary BS supplement at the beginning of the experimental period than toward the end. Water intake was positively correlated with the dietary 0.3% BS level (p<0.05). Breast meat composition and cholesterol levels were also not affected by BS supplementation. The total protein, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol levels in the blood were not significantly different among treatments.

This study aims to estimate the economic cost due to at opic dermatitis in Korea. The national patient sample data (NPS) of Health Insurance Review and Assessment Service (HIRA) was used to measure the cost of illness due to atopic dermatitis, and this study included both direct and indirect costs. Direct cost is composed of treatment, medication, transportation, and caregiver’s time cost. Indirect costs associated with the loss of productivity in atopic dermatitis patients, such as absence of work, income loss due to premature death in the future. The results show that the socio-economic burden of atopic dermatitis is about 90 billion won in Korea. Furthermore, this study identified that children and adolescents are more vulnerable. The results of this study can be valuable for determining the priority of health policy and intervention strategies to reduce the burden of disease due to atopic dermatitis.

This study aims to explore the factors associated with drin king and problem drinking among Korean adolescents. The 2013 Youth Risk Behavior Web-based Survey (KYRBS) data was used. And logistic regression model was employed to investigate the risk factors of drinking and problem drinking. Our results show that sex, age, scholastic performance, pocket money, mental health and deviation factors are related to drinking and problem drinking. However, in the sex and educational background of their parents, the results were different from each other. In the case of drinking risk, boys are more likely to have a risk of drinking, whereas girls have more risk of problem drinking. Moreover, the educational background of their parents was risk factor in the risk of drinking whereas not in the problem drinking. These results deserve great attention, and the authorities need to keep it in perspective. It demonstrated that different health policies are essential for different outcomes, ie. the risk of drinking and problem drinking.
