This study investigates the employment and spatial mismatch as a significant acting factor of deepening urban poverty and analyses the placeness of regional labor market that the more efficient place-based labor market intervention needs to take into account. The change of unemployment rate as a regional labor market outcome in metropolitan cities is determined by the dynamic interaction between disequilibrium of labor supply and demand and employment mismatch according to various labor market conditions and its process is certainly differentiated across the metropolitan regional labor markets. In addition, it is analyzed that during the employment suburbanization the spatial mismatch puts differentiated impacts on different labor groups through human capital requirements and industry-selective job opportunities. As a result, because this whole process works with its unique process within individual regional labor markets, in order to link between urban poverty and employment mismatch and to promote problem-solving labor market intervention, we need to develop place-based policy based on the placeness of regional labor marekt.

The types of the accidents caused by intra-city buses and the changing tendencies of driving attitudes are analyzed before-and-after semi-public management system of intra-city bus system is implemented. On the basis of analysis, the measures on the decrease of traffic accidents are considered and the results are as follows. First, it showed that the traffic accidents decreased generally as a result of definition of the progresses of traffic accidents of intra-city buses before-and-after the system is implemented and with the passing of time after the system was operated. Second, the factors which influence the decrease of traffic offenses before-and-after semi-public management system of intra-city bus are the decease of violation, safe driving duty and the job security. Also the cause which mostly influence to the decrease of traffic accidents is defined. Finally, the measures of decrease of traffic accidents are arranged and proposed as a result of PROXSCAL method.

The purpose of this study was to reduce safety accidents among food employees in contracted foodservice management companies, and to help provide high-quality foodservice and assistance. For this, a survey on the different opinions of workplace safety and education by employment type and employee perceptions of environment and safety at foodservice operations was carried out. The analysis showed that among the workers many women were irregular employees. For average age, between 40 and 49 was the most frequent, and for work duration, under one year was highest. Both regular employees and irregular employees deemed "enough staff" as the most major factor for good foodservice. The regular employees and irregular employees thought "high indoor temperatures and poor ventilation in the kitchen area" and "bad work cooperation between employees" as the main problems of foodservice operations, respectively. For satisfaction with the efficiency of foodservice production system, irregular employees had higher satisfaction than regular employees. Both regular employees and irregular employees thought "the number of foodservice employees" as the foremost improvement for safety-accident prevention and work-stress improvements. Regular employees, more than irregular employees, thought improvements in foodservice production systems would have a large affect on safety-accident prevention and work-stress improvements of food workers. Both regular employees and irregular employees thought "foodservice employees' safety consciousness" was an important part of safety-accident prevention. Likewise, they responded that "lectures by the person in charge of safety education" was a good methods of safety education, and "once a month" was the best period for safety education. For the difference in perceptions of environment and safety in foodservice systems, regular employees had a higher perception of safety than irregular employees.

Holographic data storage system (HDSS) features short access times, high storage capacities, and fast transfer rates, since the data is recorded and read not by lines but by pages within a volume of holographic material. Burst error caused by physical impact on the high density storage system becomes very longer than that of conventional storage systems. This paper proposes an LDPC product code using two LDPC code to resolve burst error. When a total code rate is similar, the performance of two LDPC code having high code rate is better than that of one LDPC code having low code rate. Also, with error factors of two-dimensional intersysbol interference and misalignment, the proposed scheme can improve the performance in holographic data storage system.

1970년대 이후 도시 중심의 급속한 공업화 정책을 추진한 결과, 농촌의 저발전 문제에 직면하고 있다. 1980년대 중반부터 이에 대한 대응전략으로서 농공단지 개발을 통한 산업유치, 농산물 가공산업 개발 및 유통체계 개선, 관광농업 개발 등이 논의되어 왔다. 오늘날에 와서는 WTO 체제 하에서 농산물 무역자유화가 보편적인 규범으로 자리잡아 가면서 이러한 변화를 더욱 재촉하고 있다. 이 글의 목적은 농공단지와 관광농원을 중심으로 우리 나라 농산업 발전과정을 고찰하고, 향후 발전 방향을 제시하는 데 있다. 농공단지와 관광농원 육성사업의 특성과 성패요인을 분석하는 데 있어서 이용된 자료는 주로 2차자료이다. 농공단지조성사업의 성과에 대한 많은 논란에도 불구하고, 개량적인 지표는 그것이 농촌지역경제 활성화에 직간접적으로 공헌하였음을 보여준다. 농촌노동력의 66.1%를 고용하고, 이들에게 1인당 월 평균 70만원 이상의 소득을 제공해 주었으며, 서비스업 등 관련산업의 성장에도 영향을 미쳤기 때문이다. 그러나 농공단지조성사업은 많은 문제점도 안고 있다. 농촌지역에 숙련 노동자가 부족하며 직업훈련 기회 및 창업지원 프로그램이 도시지역에 집중되어 있다. 또한 입주 기업이 농산물이나 골재 등 현지 자원을 활용하는 경우가 매우 적은 것으로 나타나고 있다. 이에 대한 대응책으로서 농촌 주민들이 손쉽게 참여할 수 있는 직업훈련 프로그램을 개발하여 제공해야 하며, 경영과 시장정보 분석 등을 기술적으로 지원할 수 있는 효과적인 지도체계를 구축해야 한다. 관광농업은 새롭게 떠오르는 산업이다. 아직 기반이 취약하지만 국가 경제성장과 도시화 진행 추이에 비추어 볼 때 관광농원은 점차 증가할 것으로 전망된다. 하지만 이 산업의 지속적인 발전을 위해서는 정책의 유연성을 확보해야 하고, 농원운영자의 경영능력이 향상되어야 하며, 수요의 계절성을 극복해야 하는 등의 과제를 안고 있다. 또한 공동운영 형태의 농원에 있어서는 참여자들을 효과적으로 조직하고, 토지소유권 분쟁을 해소해야 하는 문제가 있다. 무엇보다도 아직 이 산업의 기반이 취약하다는 전제 위에 점진적이고 지속적인 재정과 기술지원이 요청되고 있다. 다양한 운영 프로그램의 개발과 지역내 네트웍 형태의 연계개발 방식의 채택이 필요하며, 관광농원이나 농어촌휴양지 개발지역에서는 산업개발 및 주거지 개발계획이 관광여건 조성과 총체적으로 연계되어야 할 것이다.

The purpose of this study is to verify the relationships among innovative behavior, turnover intention, and job security. An additional purpose was to examine partial mediating effects on psychological ownership. The baseline of analyzing those relationships in this study is that the role of psychological ownership will be a mediator between job security and turnover intention as well as innovative behavior in the organization. To accomplish these purposes, a model was built among job security as predictor variable, the psychological ownership as mediating variable and turnover intention, and innovative behavior as criteria variables based on the studies conducted in the various areas. The 248 questionnaires surveyed from the area of DaeGu and Kyungbuk were used in the statistical analyses. The detail statistical techniques are such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, and multi regression analysis. The results of the study show that job security had positively significant effect on turnover intention and innovative behavior. In addition, only the psychological ownership of organization-level thinking have partial mediating effects between job security and innovative behavior also job security and turnover intention. The results may indicate that the psychological ownership of organization-level thinking be a key factor to alleviate the turnover intention of employees and to encourage the innovative behavior during their works for the small-medium size companies showing the unstable job security.

The aim of this paper is to make projection of the demand for export loaded container throughput originating at Incheon port in Korea over the period in question. Systematic analysis is used as a forecasting method instead of quantitative analysis. First of all, the method explores coincident indicators which may reflect the square measure of neighboring industrial complexes which originate/destinate general cargo in export traffic trends. It is noted that in terms of the export loaded container throughput, per unit production scale is intermediated transforming from square measure of production facilities to freight weight in Korea. Consequently, the future progress of the volume can be anticipated relying on the development schemes for developing square measure out of the total square of the industrial complexes. Thus, moving-into percentage of the industrial complexes, percentage of business categories, percentage of capacity and percentage of passing through via Incheon port are adopted and the future traffic demand is projected taking advantage of them.

GTA (Gas Tungsten Arc)용접은 불활성 분위기에서 용접이 이루어지기 때문에 타 아크용접법에 비해 용접부 품질이 우수하여 고품질이 요구되는 산업분야에 널리 이용되고 있다. 하지만 스테인리스강으로 pipe를 제조하기 위해 GTA 용접을 적용할 경우, Laser 및 고주파 용접 (HFIW)에 비해 용접부 품질 및 용접속도가 낮기 때문에 pipe를 제조하는 산업에서 적용에 제한을 받고 있다. 하지만, GTA는 laser 혹은 HFIW에 비해 가격이 1/10수준으로 낮고, 용접부 gap tolerance 및 용접면 관리범위가 넓은 장점이 있기 때문에 GTA의 용접속도 및 용접품질을 향상시키기 위한 연구가 꾸준히 진행되고 있다. 일반적으로 스테인리스강 GTA용접 시 용접속도를 향상시키기 위해, 모재의 성분 제어 (합금성분 최적화-Al, S, Se, O등), Flux 도포 기술 (산화물을 용접전에 도포하여 용접속도 향상) 및 혼합보호가스 적용 등이 있다. 스테인리스강 용접 시 보호가스로는 용접부 품질을 확보하기 위해 Ar을 주로 사용하고 있다. 하지만 용입 특성을 향상시키기 위해 아크의 온도를 높일 수 있는 He, 혹은 $H_2$ gas를 단독 혹은 혼합하여 사용하고 있다. 오스테나이트계 스테인리스의 경우 용입특성을 향상시키기 위해 Ar에 $H_2$를 2~10%정도 혼합하여 사용하고 있다. 페라이트계 스테인리스강은 수소에 대한 고용도가 상대적으로 작아 용접부 수소 취화를 일으킬 수 있기 때문에 적용에 제한을 받고 있어 그 대안으로 산소를 극히 소량을 혼합하여 용입성 향상에 대한 연구가 보고 되고 있다. 따라서 본 연구에서는 페라이트계 스테인리스강의 용입특성을 향상시킬 목적으로 Ar에 산소를 미량 첨가 (1%미만) 하여 용접전류 및 산소 함량에 따른 용입특성의 변화에 대해 연구하였다. 또한 기계적인 물성 및 부식특성을 평가하였고, 최종적으로 실용화 가능성을 파악하기 위해 용접전극의 수명 테스트를 실시하였다. 실시한 결과, 산소가 첨가량 증가 할수록 용입특성은 상승하였으며, 기계적인 물성 또한 산소를 첨가하지 않은 경우에 비해 거의 유사한 값을 얻을 수 있었다, 하지만 산소함량이 증가 할수록 전극의 수명은 감소하여 교체주기가 증가함을 알 수 있다. 본 연구를 통해 얻어진 기술을 상용화시키기에는 극복해야할 문제가 있지만, 소재 합금성분 설계 시 용접생산성 향상위한 산소성분 범위를 제시할 수 있으리라 판단된다.

What is the role of welfare discourse? Michel Foucault suggests the power and knowledge relation that power in a particular society and period controls the society and members by creating knowledge affecting the formation of cognitive and normative systems. Having the formation of exclusions(constraint of cognition), and materiality and reality(normative system) as an analytical framework, this article attempts the exploration of welfare discourse analyses with public statements relating to welfare subjects of the four former Korean presidents. As a result, It is found that dominant epistemic system is formed by balancing welfare and growth and regarding jobs as the best welfare(the linkage of welfare-growth-employment), emphasizing individual economic responsibility and self-reliance, pursuing welfare selectivism, and excluding comprehensive welfare provisions. At the same time, it is observed that power is not always formulating systematic knowledge and that there is a gap between cognition and norm. While the Foucauldian discourse analysis provides a causal inference about low social welfare expenditure, excessive focus on the role of power as knowledge generator and infuser causes a question of how to accommodate contemporary changes into knowledge system.

In Seoul, the subway system has been in use since 1974 and is the most frequently used travel mode accounting for approximately 40% of passenger journeys in 2015. As such the subway system is widely adopted by people and therefore, can have great impacts on their everyday life. However, it is easily noted that transit resources are not distributed spatially uniform, in other words, not all parts of the city gain the same benefits from their networks. This study aims to examine the inequity of spatial distribution of subway networks based on accessibility. Accessibility of subway networks are calculated based on the time-distance between stations and then equity is measured using the Gini index. Resulted map of subway accessibility shows that the benefits are not evenly distributed in Seoul with a pattern of highly accessible core - less accessible periphery areas. Also the subway accessibility network has fairer distribution against the employees' distribution rather than the distribution of general population or possibly transit dependent groups.
