Sodium intake has been associated with the health-related quality of life (HRQoL). This study examined the demographic factors related to HRQoL and whether there is an association between sodium intake and HRQoL in adults residing in rural areas. A total of 1,980 adults (aged ≥20 years) were selected from a cross-sectional study conducted between December 2013 and February 2014 in Gyeongju, South Korea. The sodium intake and HRQoL were measured using a validated food frequency questionnaire and the EuroQol Five-Dimension (EQ-5D) (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), respectively. The education levels (<5 years) were inversely associated with all five dimensions of HRQoL. Men had better EQ-5D scores for each of the five components examined. Adults living with spouses had better scores related to usual activities and anxiety/depression, whereas widowers had decreased scores of mobility and self-care. Unlike older adults aged 70-79 years, adults aged <60 years were more likely to have greater scores related to mobility, usual activities, and pain/discomfort. The income levels were also inversely related to the scores for self-care, usual activities, pain/discomfort, and anxiety/depression. Sodium intake was positively associated with the HRQoL related to self-care, usual activities, and pain/discomfort, but it was negatively associated with anxiety/depression. In conclusion, these findings suggest that the demographic factors and sodium intake were independently associated with HRQoL. The results highlight the need to provide tailored, targeted policies and interventions that consider personal characteristics and dietary intake to improve the overall HRQoL in adults residing in rural areas.

본 연구는 조직문화와 직무만족, 조직몰입, 조직시민행동과 같은 조직유효성 간의 관계에 사회적 자본의 매개효과가 있는지를 검증하는 것이다. 병원조직 구성원을 대상으로 조사한 바에 의하면, 전체중심 조직문화가 강할수록 조직동일시 수준과 대인간 신뢰에 대한 지각이 높게 나타났다. 전체중심 조직문화는 직무만족, 조직몰입, 그리고 조직시민행동에 모두 정(+)의 영향을 미치는 것으로 나타났다. 조직동일시와 대인간 신뢰는 각각 직무만족, 조직몰입 그리고 조직시민행동

21C 정보화시대에 정보화에 대한 사회적 요구는 날로 증대하고 있다. 교육부문에 있어서도 설비의 지원 현황등의 교육 실태의 분석을 통한 시대의 변화에 부응하는 효율적이고 합리적인 교육정보화에 대안을 수립 해야한다. 따라서 본 연구의 목적은 우리나라 및 선진국의 교육정보화사업 현황을 분석하고 사례지역(전라북도)의 정보통신기술(ICT) 활용 중심의 교육정보화 사업의 실태를 파악·분석하여 교육정보화사업 정책수립의 방향설정에 기초자료를 제공하며 학교 교육정보화의 균형적인 발전에 기여하는데 있다.

The objective of this study was to evaluate associations between airborne manganese and blood manganese in a general population of South Korean adults. The concentrations of airborne manganese in total suspended particulate (TSP) were calculated from data obtained from ambient air-monitoring stations (AAMSs) located in South Korea. Blood manganese data obtained Korean National Health and Nutrition Examination Survey (KNHANES) using a rolling sampling design involving a complex, stratified, multistage, probability cluster survey of a representative sample of the non-institutionalized civilian population of South Korea. Airborne manganese geometric means was 46.10 ng/㎥, blood manganese geometric means were 1.19 ㎍/㎗ for male and 1.40 ㎍/㎗ for female. In multiple linear regression analysis of log transformed blood manganeseas a continuous variable on airborne manganese, after adjusting for covariates including gender, age, job, smoking and drinking status, education level, BMI (body mass index). Airborne manganese was positively associated with blood manganese with statistical significance. The present study confirms that airborne manganese is a possible contributor to the increase of blood manganese in the adult general population.
