본 연구에서는 부산, 경남 주민의 중요한 식수원인 낙동강에 큰 영향을 미치고 있는 금호강을 대상으로 하여 난분해성 물질이며 내분비계 장애물질인 PCBs의 분포 상태를 조사하였다. 금호강 저니토에서의 PCBs 분석은 용매 추출법을 사용하였고 실리카 겔과 플로리실 칼럼을 통과시켜 정제한 다음 GC-ECD로 분석하였다. 모든 조사 지점에서 26개 congener가 고루 검출되어 있는 것으로 보아 금호강으로 유입되었던 PCBs의 종류는 다양했던 것으로 추정되고 금호강 유역의 저니토에 축적되어 있는 PCBs가 낙동강 하류로 유입될 수 있을 것으로 판단된다.

2002년 이후 지속되어온 미국의 재정적자가 금융위기 중 확대되면서 미국 국가채무가 2012년에는 GDP를 초과할 것으로 전망된다. 미 의회는 5개월 이상 협상을 지속한 결과 2011년 8월 1일 국가채무 한도 상향조정을 포함한 예산통제법을 통과시켜 국가부도사태는 발발하지 않았다. 이러한 미 의회의 국가채무 한도 상향 조정에도 불구하고, S&P는 지난 8월 3일 미국의 국가신용등급을 AAA에서 AA+로 강등하였으며, 주식시장의 경우도 미국의 재정지출 감축으로 인한 경기회복지연, 신용등급 강등 영향으로 인한 국제금융시장의 위험자산 회피현상으로 급락하였다. 미국 재정지출 감축과 위험자산 회피현상에 따른 우리나라의 국내총생산 감소는 미미할 것으로 분석되지만, 재정긴축 계획으로 향후 5년 동안 미국 경제에 평균 -0.5%정도의 GDP 감소 효과가 있으며, 우리나라 GDP도 평균적으로 -0.02% 정도 감소시킬 것이다. 이에 따라 우리나라 기업들도 미국 재정긴축 및 신용등급 강등으로 인하여 발생할 수 있는 사항들을 다각적으로 분석하여 대처를 할 필요성이 제기되고 있다. 다음은 대외경제정책연구원에서 발표한 "미국 재정긴축 및 신용등급 강등의 효과분석"의 주요 내용을 정리 요약한 것이다.

북한이탈주민의 입국자가 곧 3만 명에 육박할 것이다. 이로 말미암아 북한이탈주민에 대한 한국사회에서의 안정된 정착이 큰 문제로 대두되고 있기에, 그 문제들을 해결하고자 창업교육을 실시하여 북한이탈주민의 경제적 고립을 막고, 한국사회에서 올바른 진로를 선택하여 미래 통일 역군을 만들고자 한다. 본 논문은 창업교육 전, 후 창업동기 및 의지, 기업가정신, 진로장벽, 진로성숙도, 진로미결정 요인을 분석하여 창업교육에 대한 효과성을 강조하고자 한다. 아울러 장지적으로는 국내 입국 후 북한이탈주민들이 느끼는 심리를 분석하여 그들이 진정으로 원하는 진로와 정부지원정책을 도출해 내고자 한다.

In this paper, we introduce a modified short-circuited stub bandpass filter suitable for ultra-wideband(UWB) applications utilizing low temperature co-fired ceramic(LTCC) technology. By modifying the conventional short-circuited stub bandpass filter structure with stubs and connecting lines of lower characteristic impedances, the number of stubs has been reduced from 5 to 2 on a high dielectric constant substrate($\varepsilon_r$ = 40). A wireless local area network (WLAN) stopband in the frequency range of 5.15 to 5.825 GHz has been inserted into the filter characteristic using three short-circuited coupled lines. The filter has been measured with an insertion loss less than 1.0 dB and return loss better than 10 dB in the pass bands. A bandwidth ratio of 109.49 % has been achieved. Measurement results agree well with simulation results. The dimensions of the filter are $4{\times}8{\times}0.57\;mm^3$.

This study was conducted to analyze the running stability of a semi-crawler type mini-forwarder. The running stability analysis was performed by using a dynamic analysis program, RecurDyn. Physical properties of the semi-crawler type mini-forwarder was performed by using 3D CAD modeler, AutoCAD 3D. As a result from the computer simulation of stationary sideways overturning, it was found that the semi-crawler type mini-forwarder runs safely on a road with a slope not bigger than $20^{\circ}$ regardless whether it is empty or loaded, but in case of a road with a slope bigger than $20^{\circ}$, it is assumed that it is difficult for the car to run safely due to some dangers. In addition, it was found that the critical slope of its sideways overturning gets much smaller when empty since the location of its gravity center is elevated and much higher when it is loaded. As a result from the computer simulation of its hill-climbing ability, since the running speed is unstable in case of a road with a vertical slope not smaller than $28^{\circ}$, it is assumed that it is safe to drive it on a road with a slope not bigger than $28^{\circ}$. Taking a look at the result from an analysis of the running safety when it passes an obstacle, it was observed that a front tire comes off the ground when the running speed of the car is 5 and 4 km per hour respectively when it is empty and loaded while the gravity center of the front tire is watched. When taking a look at the changes in the location of the gravity center of the rear wheel crawler shaft, it was not found that the shaft comes off the ground at the test speeds both when it is empty and loaded.

This study examined the morphological, physical and chemical characteristics of the Yesan and the Songjeong series derived from residuum of the granite developed on gently sloping to rolling relief in Honam reclamable land Area. The results of this study are summarized as follows. 1. The morphological characteristics. In the Yesan series, the surface soils(Ap horizons) are brown to dark brown sandy loam. The subsoils(B horizons) are yellowish red to red sandy clay loam to sandy loam and the soil profile development is weak. The Songjeong series, the surface soils (Ap horizons) are washed by erosion, so the subsoils are revealed on the surface, and these are dark red silty clay loam. The subsoils (B horizons) are red silty clay loam and thin clay cutans are formed on the ped faces of the structure. The substrata of two soil series are deeply weathered granitic saprolite. 2. The physical and chemical characteristics. The distribution of clay content tends to increase from surfaces to subsoils with depth gradually. On the Yesan series, the content of clay is less than 18%, soil pH (6.0 in the surface-soil, 4.5-5.0 in the subsoil), the content of organic matter (1.8% in the surface soil, 0.1~0.4% in the subsoil), available phosphate (40 ppm), the cation exchange capacity(4~8 me/100 gr) are very low, and the base saturation (57.8% in the surface soil, 46.3% in the subsoil) is moderate. On the Songjeong series, the content of clay is 30~40%, pH (5.7-6.0), the content of in organic matter (1.25% in the surface soil, 0.1~0.4% in the subsoil), available phosphate(4 ppm), the cation exchange capacity(6.2 me/100 gr in the surface soil, 2~6 me/100gr in the subsoil) are very low, and the base saturation(28.1% in the surfacesoil, 16~23% in the subsoil) is also low. 3. The Yesan and Songjeong series are for med under a temperate humid climate, and classified as Red Yellow Soils in the old classification system. According to U.S.D.A. 7th approximation the former belongs to Typic Dystrochrepts in Inceptisols, and the latter, Typic Hapludults in Ultisols.

This paper proposes GAPS, a practical genetic algorithm based pathfinding system for conveniently analyzing various networks. To this end, the GAPS is developed through integration of the intuitive graphic user interface for network modeling, the database management system for managing the data generated in modeling and exploring procedures, and a simple genetic algorithm for analyzing a wide range of networks. Especially, previous genetic algorithms are not appropriate for analyzing the networks with many dead-ends where there are few feasible paths between the given two nodes, however, GAPS is based on the genetic algorithm with the fitness function appropriate for evaluating both feasible and infeasible paths, which enables GAPS to analyze a wide range of networks while maintaining the diversity of the population. The experiment results reveal that GAPS can be used to analyze both networks with many dead-ends and networks with few dead-ends conveniently, and GAPS has several advantages over the previous genetic algorithms for pathfinding problems.

This article examines the relationship of career indecision, job search behavior, and employment among college seniors based on sub-scales of career indecision (lack of career information, lack of self-clarity, decisiveness, lack of necessity recognition, external Barrier). This study explored the effect of career indecision, job search behavior, and employment successes(number of application, number of interview, number of job offer) in longitudinal method. In result, career indecision had negative effect on job search behavior. In other words, the higher career indecision level is, the less job search behavior is performed. Especially, career indecision is connected with preparatory job search behavior and informal job search behavior. Another finding is that job search behavior in time 1 (first semester of college senior) had a strong effect on all of employment success variables in time 2(second semester of college senior). Finally, the theoretical and practical implications of this research were discussed. Based on the limitation of this study, several directions for future research were also suggested.
