최근 들어 노인 빈곤층문제가 심각한 사회적 이슈로 대두됨에 따라, 중장년층 은퇴 전후 세대들의 소득과 소비를 중심으로 재정안정성 문제를 살펴보았다. '고령화연구패널조사'자료를 활용하여, 은퇴자그룹과 비은퇴자그룹을 나누고, 연령별 차이를 비교 분석하였다. 연구의 주요결과는 다음과 같다. 첫째, 은퇴자그룹의 개인총소득은 비은퇴자그룹의 개인총소득에 비해 소득이 3배 이상 낮았다. 둘째, '공적연금소득' 수급비율은 은퇴자그룹은 전체의 30%에 불과하고, 공적연금의 비중은 개인총소득의 40% 이하로 나타났다. '개인연금소득'은 두 그룹 모두 수급비율이 1%내외로 매우 낮은 것으로 조사되었고, 은퇴자그룹에서는 '사적이전소득'이 전체소득에서 차지하는 비중이 크다는 것을 확인하였다. 셋째, 소득이 줄어든 만큼 소비는 은퇴를 하더라도 크게 줄지 않기 때문에, 연령이 증가함에 따라 재정안정성이 낮아지는 것으로 나타났다. 넷째, 국가로부터의 노후생활 지원에 대한 기대감은 양 그룹 모두 낮은 것으로 조사되었다. 다섯째, 은퇴자그룹의 공적연금소득에 미치는 영향요인을 비은퇴자그룹 개인 총소득에 미치는 주요 요인과 비교한 결과, 성별, 연령, 학력, 건강상태가 주요 요인으로 나타났다. 본 연구는 은퇴 전후 세대의 노후소득보장을 위한 정부차원에서의 공적연금 확대와 개인연금 활성화 지원의 필요성을 제안한 점에서 기여도가 있다.

This paper proposes a novel swarm intelligence optimization method which integrates bacterial foraging optimization (BFO) with quantum computing, called quantum bacterial foraging optimization (QBFO) algorithm. In QBFO, a multi-qubit which can represent a linear superposition of states in search space probabilistically is used to represent a bacterium, so that the quantum bacteria representation has a better characteristic of population diversity. A quantum rotation gate is designed to simulate the chemotactic step for the sake of driving the bacteria toward better solutions. Several tests are conducted based on benchmark functions including multi-peak function to evaluate optimization performance of the proposed algorithm. Numerical results show that the proposed QBFO has more powerful properties in terms of convergence rate, stability and the ability of searching for the global optimal solution than the original BFO and quantum genetic algorithm. Furthermore, we examine the employment of our proposed QBFO for cognitive radio spectrum allocation. The results indicate that the proposed QBFO based spectrum allocation scheme achieves high efficiency of spectrum usage and improves the transmission performance of secondary users, as compared to color sensitive graph coloring algorithm and quantum genetic algorithm.

A fisher means any person employed to provide his/her labor in a fishing vessel in exchange for a wage. There is no concept of a fisher in Seafarers Act. This act shall not apply to seafarers who are in service on board a fishing vessel the gross tonnage of which is less than 20 tons. However, of the total 63,112 fishing vessels, only 2,829 fishing vessels have a total tonnage of more than 20 tons. Fishermen engaged in fishing vessels with a gross tonnage of which is less than 20 tons are not guaranteed to be paid arrears through the Wage Claim Guarantee Fund for Seafarer (Article 56). In addition, fishermen working on a fishing vessel are excluded from the Wage claim Guarantee Act. The Labor Standards Act shall apply to fishermen engaged in fishing vessels with a gross tonnage of which is less than 20 tons. Fishermen and seafarers are at a higher risk of living security than regular workers. Guaranteeing the payment of wages is essential for fishermen to improve the life and employment stability. In order to guarantee fisher wage claims, the concept of a fisher in the Seafarers Act must be realized by sources such as the Wage Claim Guarantee Fund of Ministry of Oceans and Fisheries, step by step expansion of members in the wage claim guarantee fund for seafarers and interest for delayed payment of wages, etc.

Electrolytic in-process dressing grinding technique which enables application of metal bond wheels with fine superabrasives in mirror surface grinding operations has developed. It is possible to make efficient precision machining of hard and brittle material such as ceramic and hard metal by the employment of this technique. However, in order to ensure the success of performances such as efficient machining, surface finish, and surface quality, it is important to sustain the insulating layer that has sharply exposed abrasives in wheel surface. Using AE(Acoustic Emission) sensor, this paper will show whether the insulating layer sustains stably or not in real grinding time. And by comparing AErms value and surface roughness their thresholds for stable electrolytic in-process dressing grinding will be determined.

본 연구는 2010년 조기재취업수당 제도 변화 전후의 수급자 특성을 살펴보고, 실업자 재취업 촉진에 대한 성과 변화를 살펴본다. 조기재취업수당 수급자에 대한 특성 분석 결과, 제도 변경 이후로 여성 및 고령층의 수급확률이 증가하고 중졸 이하 저학력층의 수급확률이 증가하였다. 이는 실제 수혜집단이 취업 애로계층으로 다소 전환되어 노동시장 취약집단의 취업촉진이라는 조기재취업수당의 정책 목표에 보다 근접해졌음을 시사한다. 제도 변경전 후의 재취업률과 재취업된 일자리 유지율을 비교한 결과, 재취업률에는 큰 변화가 없어서 수급요건 강화로 인한 구직자의 재취업 유인 감소 효과가 크지 않은 것으로 판단된다. 이와 더불어, 조기재취업수당 수급자의 재취업 일자리 유지율은 제도 변화 이후 높아진 것으로 나타났다.

The objective of this study is to examine and provide guidelines for regional governments, communities, and the private sector in planning and implementing poverty-reduction activities that are more effective, efficient, and targeted. Besides, this research's specific aims are: 1) increasing the rate of regional economic growth through optimization of potential sources of local income, 2) increasing per-capita income, and 3) reducing poverty, unemployment, and social-economic inequality of the community. The study was conducted in North Morowali District, Central Sulawesi Province, Indonesia, in 2018-2019. The research approach used quantitative and qualitative descriptive analysis. Data sources include sources from the Focus Group Discussion (FGD) and Regional Statistics. The results of this study are based on the Millennium Development Goals (MDG's) indicators that there are four priority scales in poverty reduction, namely, Health and Infrastructure (Priority I), Education (Priority II), Food stability (Priority III), and Population and Employment (Priority IV). Therefore, as a solution to poverty alleviation strategies, the cost approach through regional economic optimization and local income sources and community empowerment factors are essential. Apart from that, the involvement between elements (government, organizations, society, universities, and institutions) is expected to continue as an effort to realize poverty reduction can be optimally overcome.

Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.
