The National Pension of Korea is a public social security system designed to alleviate social risks and poverty that has had a major impact on the quality of life for the aging population. However, a rapidly aging population and low fertility threaten the sustainability of national pension in Korea. The National Pension Research Institute publishes a nancial projection every ve years; consequently, the government has lowered the entitlements for the sustainability of national pension based on the projection results. The current reform of the pension system that arbitrarily reduces the entitlements might detract from the income security role of the national pension for pensioners without accounting for the highest elderly poverty rate in the OECD countries. We first discuss methods for the financial projection of the national pension in terms of population, subscribers, and pensioner projections in order to estimate the pension reserve fund and the financial depletion year. We also conduct a sensitivity analysis for population variables, institutional variables, and economic variables based on pension reserves and the financial depletion year. We evaluate intergenerational fairness between the income hierarchy by conducting a money's worth analysis. Finally, we investigate the possibility of the sustainability of national pension by adjusting pension contributions and entitlements (income replacement rate). A new dependency ratio shows that a simple reform of the national pension does not secure the sustainability of the national pension without adapting a pay-as-you-go system.

한국 사회의 인구 고령화 속도는 세계 최고 수준으로 향후 보건, 의료, 복지 등에서 심각한 사회 문제를 발생시킬 것으로 예상되고, 고령화 사회로 인한 질병 발생률의 증가는 국민 의료비 부담의 증가로 이어져 이에 대한 대책이 필요하다. 이에 따라, 정보통신기술을 이용하여 시간과 공간에 구애받지 않고 언제 어디서나 건강과 생활을 관리하여 건강한 삶을 유지시키는 새로운 형태의 서비스인 유헬스케어(u-Healthcare)가 많은 주목을 받고 있다. 최근에는 일반인, 고령자, 만성질환자를 대상으로 하는 유헬스케어용 건강 개인 기기의 개발이 확산되고 있으나, 표준이 없이 업체별로 제품개발이 이루어지기 때문에 서비스간 호환성 등의 문제가 생기고, 이로 인해 유헬스케어 산업의 성장에 장애요소로 작용하고 있다. 이를 해결하기 위해, 최근 헬스케어 분야의 표준화가 활발하게 진행되고 있으며, 표준화를 통해 생체정보 데이터의 취합 및 전송, 분석 및 피드백이 표준적인 방법으로 운용이 될 수 있도록 하고 개인 건강 기기들과 유헬스케어 서비스간의 상호 운용성이 보장이 될 수 있도록 할 수 있다. 본 고에서는 최근 헬스케어 분야에서 가장 활발하게 표준화가 진행중인 IEEE 11073 PHD 표준화 동향과 HL7 CDA의 표준화 동향에 대해서 상세히 살펴보고, 본 연구원에서 개발한 국제 표준기반 유헬스케어 플랫폼에 대한 소개를 한다.

최근 한국은 지구환경 변화에 따른 기후변화 영향으로 집중호우로 인한 도시홍수가 급증하고 있다. 기상변화에 의한 집중호우와 급증된 도시화로 인해 불투수면적이 증가하고, 이는 홍수시 유출량을 증가시켜 기존 하도 또는 내배수 시스템의 적정 소통량을 초과하여 홍수를 발생시킨다. 그리하여 홍수피해를 저감하기 위해 구조적 및 비구조적 홍수방어대책들이 마련되어 시행하고 있다. 하지만 내수배제시설의 경우, 기존의 치수계획이 빗물펌프장 등 일부 구조물에 한정되어 있기에 해당 홍수방어시설에 과도한 부담이 있는 실정이다. 따라서 유역 내에 투수면적을 최대한 확보하여 토양의 수문학적 특성을 유지 보전시켜 첨두유량, 도달시간, 직접유출량을 도시 개발 이전상태와 최대한 유사하도록 하는 홍수유출저감시설을 설치하여 빗물펌프장과 같은 홍수방어시설에 대한 과부하를 덜어준다. 이러한 홍수유출저감시설은 크게 저류시설과 침투시설로 구분된다. 홍수유출저감시설들은 해당 지역의 입지특성, 재해저감효과 및 제약조건에 따라 설치 위치 및 규모가 결정된다. 또한 저감효과는 CN 값의 변화로 정량화하여 시설의 적합성을 판단할 수 있다. 본 연구에서는 SWMM 모형을 이용하여 김천시의 평화배수분구지역을 대상으로 CN 저감을 기반으로 한홍수유출저감시설을 평가하고자 한다.

우리나라 기업 창업 후 5년까지 생존율(27.5%)은 OECD 평균 생존율(43.9%)보다 낮으며 최근 5년간('11~'15년) 연평균 창업은 81만개, 폐업은 70만개로 다산다사(多産多死) 특징 보유하고 있다. 사업 실패로 인한 폐업은 개인적인 차원을 넘어 사회적인 문제로 확대되고 국가 경제에 부담으로 작용하고 있다. 이에 본 연구에서는 사업실패경험이 학습효과와 자산으로 승화하여 재창업의지에 직접적인 영향을 미치는지, 사업실패자에 대한 사회적지지가 재창업 의지에 어느 정도 상승효과를 주는지에 대해 분석하기 위해 사업실패자자들을 대상으로 자료를 수집, 실증 분석하였다. 본 연구 결과는 첫째, 사업실패경험 속성중 비재무적 손실이 발생한 경우 재창업의지에 부(-)의 영향을 미치는 것으로 나타났다. 이는 비재무적 손실이 크다면 재창업의지는 낮아지게 된다. 둘째, 재무적 손실이 발생한 경우에는 재창업의지에 영향을 미치지 못하였다. 셋째, 조절변수인 정서적지지는 비재무적 손실이 발생한 경우 재창업의지에 정(+)영향을 미치는 것으로 나타났다. 따라서 재창업지원은 이들이 경험한 비재무적 손실을 회복 할 수 있도록 정서적지지를 활용하는 다양한 정책안들이 고안 되어야 하고 사업실패로 재무적 손실이 크게 나기 전에 사업을 빠른 시일 내에 정리토록 하는 것이 재도전 시책에서 무엇보다 중요하다는 시사점을 주고 있다.

This study comparatively analyzed the impact of childcare workforce cost on fertility rates across different countries. In the cases of Nordic countries, comprehensive childcare support policies and subsidies for childcare workforce costs were found to have a positive impact on fertility rates. In contrast, high childcare burden and economic pressures were identified as major factors contributing to declining fertility rates in East Asian countries. In developing countries, the effectiveness of childcare support policies varied depending on the socioeconomic context. This study suggests that the impact of childcare workforce cost on fertility rates manifests in diverse patterns across countries, and effective childcare support policies require tailored approaches that consider each country's specific circumstances. In the future, increased social investment in childcare and the spread of a culture that respects the value of care are necessary.

Private detectives and investigators offer many services, including executive, corporate, and celebrity protection; pre-employment verification; and individual background profiles. They also investigate computer crimes, personal injury cases, insurance claims and fraud, child custody and protection cases, missing persons cases, and premarital screening. This paper focuses on a private detective or investigator system in most developed U.S.A, but it is not easy to describe that system. Licensing requirements vary in U.S.A. Some States have few requirements, and many other States have stringent regulations. A growing number of States are enacting mandatory training programs for private detectives and investigators. Employment and need of private detectives and investigators is expected to grow faster than the average for all occupations. Thus, it is reasonable that korean government should permit private investigation service find the way to minimize the side effects of private investigation service instead of banning the service totally.

After global financial crisis, the ratio of household debt to GDP was decreasing in other advanced countries such as the U.S., and the U.K. and so on. But, in Korea, household debt (of which residential mortgage loan account for a large part) ratio is still increasing. This paper focuses on the scale and characteristics of households in negative housing equity (those are called House-poors in Korea), and also the socio-economic backgrounds of the formation process. In financial perspective, the problem of negative housing equity depends on financial debt repayment capability. We used DSR (Debt Service Ratio) and LTA (Loan to Asset ratio) as financial indicators to evaluate the debt repayment capability. The critical value of DSR is assumed as 40%, and LTA 100%. The socio-economic backgrounds of the House-poors are as follows : increasing households debt dependency, over lending competition of financial institutions and unreasonable loan in household economy, instability of real estate market, week regulation on mortgage loan. Finally, this paper suggests some implications about the range and the target of public intervention.

This study examined the factors affecting family caregiver's preference for utilization of community care services among those who are caring for 65+ elderly parents, and aimed to show how social eldercare services would be settled in Korea. Help-seeking behavior model developed by Anderson and Newman(1973) was used to analyze the factors affecting their preference for utilizing the community care service among 283 family caregivers. Frequency, Chi-square, and Multinominal logistic analysis on SAS 6.12 was used. According to the results, about 90% of the family caregivers have preference for community and institute care services. In community care service, about a half comprise the preference with charge while the other without charge. However, about 90% of those for institute care service show their willingness to pay for the service. Also, a majority of caregivers like to rely on social eldercare service, rather than family as exclusively responsible, against long-term care for their elderly parents. Multinominal analysis demonstrates that use versus nonuse of community care services is primarily affected by predisposing factors(including age, carer-caree closeness, and familism) and need factors (including economic or psychological burden of eldercare, and additional role for family care). Enabling factors, such as family income level, economic support from other family members and siblings, and supportive care-helpers, are mainly associated with the preferences of free versus charge in service use. These findings provide some implications and suggestions for the development of social eldercare services in our aging society.

Korea is undergoing a change in its population structure, due to economic development, falling birth rates and the development of health care. As the population ages, the number of elderly people who have difficulty in daily life such as dementia and paralysis increases every day. The growth of nuclear families and the increased participation of women in society make it difficult to take care of elderly people who need long-term care at home. As the social problems resulting from this have emerged as serious problems, the government enacted and implemented the Long Term Care Insurance Act to improve the quality of life for the elderly subject to long-term care and to ease the burden of family support in order to solve such problems. Therefore, the present study explores ways to improve legal and institutional aspects, and seek mental and psychological measures for the stability of old life as well as the physical health of welfare.
