Background: This study aimed to examine the association between educational level and unable to work due to ill-health (UWdIH) among 30- to 79-year-old South Koreans. Methods: A cross-sectional nationwide survey of the 2010-2016 Korea National Health and Nutritional Evaluation Survey was used for analyses. A total of 29,930 participants aged ≥30 and < 80 years, who do not have any disability in their daily life because of health problems, were included. Educational level and reason for nonworking are self-reported with multiple choices. Multivariate logistic regression was used to examine an association between education level and UWdIH by setting those who graduated college as their final education (n = 6,997) as a baseline while controlling for potential confounding factors. Results: In the age-stratified result, the ratio of UWdIH was increased as age increases in 3 educational groups (p < .0001). There was a tendency that low-level educated [International Standard Classification of Education (0-2)] participants showed higher ratio of UWdIH than high-level educated [International Standard Classification of Education (5≤)] participants in both sexes (odds ratio: 2.54, 95% confidence interval: 2.12-3.05). Conclusion: There is a clear link between educational level and UWdIH; the less the educated, the more likely to be UWdIH. Policy priority should be given to plans that can help this vulnerable social group to work and enjoy healthy lives.

Public expenditures on long-term care are a matter of concern for Korea as in many other countries. The expenditure is expected to accelerate and to put pressure on public budgets, adding to that arising from insufficient retirement schemes and other forms of social spending. This study tried to foresee how much health care spending could increase in the future considering demographic and non-demographic factors as the drivers of expenditure. Previous projections of future long-term expenditure were mainly based on a given relation between spending and age structure. However, although demographic factors will surely put upward pressure on long-term care costs, other non-demographic factors, such as labor cost increase and availability of informal care, should be taken into account as well. Also, the possibility of dynamic link between health status and longevity gains needs to be considered. The model in this study is cell-base and consists of three main parts. The first part estimated the numbers of elderly people with different levels of health status by age group, gender, household type. The second part estimated the levels of long-term care services required, by attaching a probability of receiving long-term care services to each cell using from the sample from current year. The third part of the model estimated long-term care expenditure, along the demographic and non-demographic factors' change in various scenarios. Public spending on long-term care could rise from the current level of 0.2~0.3% of GDP to around 0.44~2.30% by 2040.

This paper discussed about business ethics and innovation management performance of IT service firms in Korea. To prove empirically the research hypothesis, the statistical analysis was based on the response from the 92 IT Service firms in Korean. As analysis results, it was found that the business ethics of organizations were the effect factors of the innovation management performance. And the knowledge competency and creativity are confirmed as a mediator between the business ethics and innovation management performance. So this paper suggests that business ethics in organizations are the important factor for enhancement of IT service firm's innovation performance. Specially the mediation effects of knowledge competency and creativity variables were proved empirically for the relation between the business ethics and innovation management performance. So it is desirable that knowledge-based service firms, for example IT service firms, have to strive to upgrade their level of business ethics and to link with their creativity and knowledge competency.

Whether it is crosstalk, harmonics, or in-band operation of wireless technologies, interference between a reference system and a host of offenders is virtually unavoidable. In past contributions, a benchmark has been established and considered for coexistence analysis with a number of technologies including FWA, UMTS, and WiMAX. However, the previously presented model does not take into account the mobility factor of the reference node in addition to a number of interdependent requirements regarding the link direction, channel state, data rate and system factors; hence limiting its applicability for the MBWA (IEEE 802.20) standard. Thus, over diverse modes, in this correspondence we analytically derived the greatest aggregate interference level tolerated for high-fidelity transmission tailored specifically for the MBWA standard. Our results, in the form of benchmark indicators, should be of particular interest to peers analyzing and researching RF coexistence scenarios with this new protocol.

최근 교통약자의 이동권에 대한 관심이 증가하고 있으나 대부분 제도적 시설 공급측면에 치중되어 일시적 이동상의 불편함만을 해소할 뿐이며 실제 교통약자에게 향상된 이동편의를 제공하지 못하고 있다. 따라서 본 연구에서는 교통약자의 보행에 영향을 미치는 경사로, 계단과 같은 물리적 장애 요소들을 고려하여 교통약자 유형별 최적경로를 탐색하는 기법을 제안함으로써 교통약자의 이동편의를 직접적으로 향상시키고자 한다. 선행연구 및 관련 제도를 분석하여 교통약자의 보행에 방해가 되는 보행장애요소를 선정하고 계층적의사결정법(Analytic Hierarchy Process; AHP)을 이용하여 각 보행장애요소의 상대적 중요도를 산정하였으며 마지막으로 퍼지 시스템을 통하여 교통약자의 보행에 방해되는 정도를 나타내는 링크별 보행방해도를 도출한다. 보행방해도를 바탕으로 거리 요소를 포함한 보행 경로비용을 계산하고 이 값이 최소가 되는 경로를 다익스트라 알고리듬을 통해 탐색함으로써 교통약자 유형별 최적 경로를 제공한다. 본 연구에서 제안한 기법을 적용하여 도출된 19개 경로를 대상으로 실제 현장 실험을 통하여 각 경로에 대한 만족도 설문조사를 수행하였고 이를 통해 실제 교통약자의 이동에 편의를 향상하는 유의미한 경로가 도출되었음을 확인하였다. 본 연구에서 제안한 최적경로 탐색 기법이 내비게이션 서비스에 적용된다면 교통약자의 이동복지향상을 도모할 수 있을 것으로 보인다.
