이 논문은 건설일용직 노동자들의 사회안전망 강화를 위한 주요 조건으로서 일용직 건설노동자들의 4대 사회보험 의무가입 시행을 위한 기금확충 규모를 분석하고, 이를 추진하기 위한 정책적 과제를 탐색하는데 그 목적이 있다. 건설업은 오랫동안 국내경제에 중요한 기여를 해온 중추적 산업부문임에도 불구하고, 전체노동자의 절반이 일용직 형태의 비정규 노동자 일만큼 산업내 비정규 비율이 매우 높은 대표적 산업이다. 이러한 현실은 건설산업구조의 고유한 특성과 고용구조에서 기인한다. 본 연구에서는 건설업 내의 불안정 노동자들의 사회안전망을 강화하고 건설업의 경쟁력을 강화하는 방안으로 건설노동자들의 사회보험 의무가입이 절대적으로 필요하다는 인식아래 사회보험 의무가입을 위한 기금확충 규모를 분석하고 이를 실현하기 위해 사회보험 가입조건 완화를 비롯하여 적정임금 도입, 직접시공과 같은 구체적인 정책적 과제를 탐색한다.

Tuned mass dampers (TMD) are devices employed in vibration control since the beginning of the twentieth century. However, their implementation for controlling the seismic response in civil structures is more recent. While the efficiency of TMD on structures under far-field earthquakes has been demonstrated, the convenience of its employment against near-fault earthquakes is still under discussion. In this context, the study of this type of device is raised, not as an alternative to the seismic isolation, which is clearly a better choice for new buildings, but rather as an improvement in the structural safety of existing buildings. Seismic records with an impulsive character have been registered in the vicinity of faults that cause seismic events. In this paper, the ability of TMD to control the response of structures that experience inelastic deformations and eventually reach collapse subject to the action of such earthquakes is studied. The results of a series of nonlinear dynamic analyses are presented. These analyses are performed on a numerical model of a structure under the action of near-fault earthquakes. The structure analyzed in this study is a steel frame which behaves as a single degree of freedom (SDOF) system. TMD with different mass values are added on the numerical model of the structure, and the TMD performance is evaluated by comparing the response of the structure with and without the control device.

This paper empirically explores the nature of the medical service industry and its various propagation effects on the economy in the input-output model, as revealed by a comparative analysis between Korea and Japan. The main findings of the paper are as follows; First, the growth of medical industry induces above-average effect on employment. Second, the industry is of the characteristics of weak both backward and forward linkage effects implying a 'final demand dependency industry'. When compared with public service sectors, however, the medical services industry shows stronger backward linkage effect than those sectors. Furthermore, it has strong repercussion effects on the goods industries. Third, in order to produce per unit of services, the medical services industry of Korea uses relatively more drugs and medical devices than that of Japan. In general, it has been shown that production structure of medical service industry in Korea is 'hardware-oriented' one; on the other hand, 'software-oriented' in Japan which means that, as intermediate inputs, outsourcing and informatization has been used than those of Korea. From the findings of the paper it could be emphasized that the medical organizations in Korea should put more efforts on shifting the current hardware-oriented production structure to strengthen core competence by enhancing productivity and by outsourcing to improve efficiency of production process. However, the medical organizations in Korea would not have enough incentives for high value-added production structure because they enjoy high operating surplus. Therefore, it would be necessary that government policy should be taken into account of these environments.

이 논문은 통계청의 연구비지원으로 수행한 연구인 ‘여성인구의 특성 및 변화’의 일부로서, 인구학회와 통계청이 공동으로 개최한 <인구변화와 한국사회의 미래변화에 대한 세미나>에서 발표한 논문을 수정한 것이다. 여성의 인구구조는 지역간의 인구이동에도 불구하고 지역별로 상당히 다르고, 여성의 경제활동상태와 취업구조 또한 지역별 산업구조의 차이로 인해서 지역간에 상당한 차이를 보인다. 그럼에도 불구하고 지금까지 지역별 여성의 인구구조와 취업구조의 차이에 대한 연구가 거의 이루어지지 않고, 지방정부 또한 지역여성인구에 대한 특성을 제대로 파악하지 못하고 있다. 그 결과 지방정부가 수립${\cdot}$시행하고 있는 여성정책들의 실효성과 효율성은 상당히 낮은 것으로 평가되고 있다. 이에 본 논문은 <인구주택총조사> 2% 표본자료의 기술적인 분석(descriptive analysis)을 통해서, 지역별 여성의 인구구조, 경제활동상태, 취업구조 등에 대한 개괄적인 현황을 파악하고, 향후 지방정부의 여성정책에 대한 기본적인 방향을 제시하였다.

본 연구는 지역의 고용 구조와 빈곤과의 관계를 규명하고 이를 통해 빈곤정책의 효과를 높이기 위해서는 수급자 개인을 넘어 지역에 기반한 다양한 정책적 모색이 필요함을 제언하고자 한다. 본 연구는 소지역추정법을 통해 지역별 빈곤 공간분포와 지역의 다양한 특성과 빈곤과의 관계를 탐색한다는 측면에서 의의가 있다. 분석결과, 지역의 고용 및 산업 구조와 빈곤율의 관계는 밀접하게 관련이 있었다. 경제활동참가율과 고용율이 높을수록 지역 빈곤율은 낮아서, 최근 근로빈곤의 심각성을 시사하였다. 그리고 지역의 일자리 질은 부분적으로 지역의 빈곤율을 낮추는 효과가 있었다. 지역의 산업 구조와 빈곤율의 관계를 분석한 결과, 지역에 농업, 임업, 어업 종사인구가 많을수록 빈곤율은 높은 것으로 나타난 반면, 제조업, 도소매업, 숙박 및 음식점업 종사자 수와 비율은 빈곤율과 부적의 관계를 보여, 도시와 농산어촌 지역의 빈곤율 차이를 보여주었다. 그간 국내의 빈곤 연구들은 가구나 가구에 속한 개인에 초점을 맞추고 있어, 빈곤을 접근하는데 있어서 보다 거시적이고 구조적인 관점에서 접근하지 못하였다. 본 연구는 이와 같은 점에서 빈곤을 설명하는 시각을 더 넓히고 빈곤문제에 대해서 다양한 각도에서 접근할 필요성을 제시하고자 하였다.

In this paper, the dynamic behavior for a group of transmission towers linked together through electrical wires and subjected to a strong ground motion will be investigated in detail. In performing the seismic analysis, the wires and the towers concerned are modeled, respectively, by using the efficient cable elements and the 3-D beam elements both considering geometric nonlinearities. In addition, to enhance the reliability and applicability of analytical outcome, a sophisticated soil-structure interaction model will be utilized in analyses. The strength capacities and the fracture occurrences for the main members of the tower are examined with the employment of the appropriate strength interaction equations. It is expected that by aid of this investigation, those who are engaged in code constitution or in practical designing of transmission towers may gain a better insight into the roles played by the interaction force between towers and wires and by the configurations of transmission lines under strong earthquake.

In this piece of work, carbon nanotubes motion equations are framed by Kelvin's method. Employment of the Kelvin's method procedure gives birth to the tube frequency equation. It is also exhibited that the effect of frequencies is investigated by varying the different index of polynomial function. By using volume fraction for power law index, the fundamental natural frequency spectra for two forms of single-walled carbon nanotubes are calculated. The influence of frequencies against length-to-diameter ratios with varying power law index are investigated in detail for these tubes. Throughout the computation, it is observed that the frequency behavior for the boundary conditions follow as; clamped-clamped, simply supported-simply supported and these frequency curves are higher than that of clamped-free curves. Computer software MATLAB is utilized for the frequencies of single-walled carbon nanotubes.
