The objectives of this paper are to analyze the effect of government R&D expenditure on employment in the Korean manufacturing sector in which employment is rapidly declining. According to the results of our empirical analysis, government R&D expenditure decreases the level of employment in Korean manufacturing sector in short term period, but it has positive effect on employment by compensation effect in the middle and long term period. Second, the effect of private R&D expenditure on job creation is three times larger than that of government R&D expenditure. Third, costs of labor and capital has negative effect on employment. This study is believed to help understanding the relation between R&D expenditure and employment, and providing policy implications of how to plan and manage government R&D expenditure as a tool of job creation.

This study is about what effect the proverb of the stock has on the investment behavior by the stock investors. It confirmed if the investors knew the stock proverb that had been used in the stock market for a long time, examined the stock investors applied this content to the real investment process, analyzed if the application influenced the investment result. For this, this study selected total 29 stock proverbs about the investment principle, diversified investment, item selection, time of buying and selling, and value tendency which were being used in the stock market and frequently quoted in the stock-related literature to conduct a questionnaire targeting 191 stock investors and analyze the result. As a result of the analysis, it was confirmed the investors of 14% applied the stock proverb to invest and created the profit through it. It is expected the stock investors and the stock market used the analyzed stock proverb statistics through these helpful study and results to apply to the stock investment.

The estimation of total travel time on highway link for a day or year is the most important process for the feasibility analysis of highway or railway. Most of current guidelines for feasibility studies have been based on the time-traffic volume relationship from the BPR, and the traffic volumes have been determined by the application of the design hour factor to the annual average daily traffic volume. Both of the BPR function and the application of the design hour volume may result in the over-estimation of travel time due to the fact that the traffic volume on the large portion of highway links in Korea are close to the capacities. This study proposed a new way which is based on the distribution of hourly volumes for a year. It could be closer to the real situation, and provide more reasonable estimation. This methodology was validated for the national highways, but may be applicable for any type of highway with the AADT.

수년간 건설업은 제조업을 비롯한 다른 산업에 비해 높은 재해율을 보이고 있다. 건설투자의 증가는 2001년과 2002년 각각 7.4%와 12%씩 증가하였으나, 재해발생건수는 2001년(16771건)은 2000년(13500건)에 비해 24% 증가하였고 2002년 상반기(8853건)는 2001년 상반기(6636건)보다 33%나 증가하여 건설투자의 증가율보다 높았다. 더욱이 건설취업자수가 2001년(1581천명)의 경우 전년(1575천명)에 비해 0.4%가 감소되었음을 감안할 때 건설물량의 양적 증가에도 불구하고 안전관리에는 소홀한 면이 많았으며 재해예방을 위한 적극적인 노력이 요구된다.(중략)

1. Interleukin-2(IL-2)를 연간 1.227㎏을 생산하는 공장의 공정 설계를 IBM PC를 사용한 Super-pro designer를 이용해서 공정 모사를 해보았다. 각 단위공정의 계산자를 정하기 위한 계산을 가정과 5L fermenter 배양의 결과를 이용하여 up-stream을 설계하고, downstream 에서는 28%의 분리정제 수율을 가정하고 전체 공정을 설계하였다. 2. 경제성 분석에 의하면 IL-2의 dose당 $20로 할 때, 투자 상환율(return on investment)이 일년에 40.63%이었으며, 투자금액의 상환에 걸리는 시간은 약 2.46년이 걸리는 것으로 나왔다.

웹캐스팅 구축에 있어서 가장 먼저 선행되어야할 과제는 사업계획의 확정에 있다. 실제로 구축에 임하는 상당수의 경우에는 체계적인 사업계획이 미비한 경우가 상당히 많은데, 사업계획을 통해 전체 구축에 소요되는 일관된 정책과 전략을 수립하기 때문에 반드시 사업계획 수립에 대한 투자를 바란다. 사업계획을 통해 사업전략, 마케팅 계획, 수익모델, 투자계획과 조직구성안 등이 체계적으로 정리되어진 후에 구축작업에 임하는 것이 시행착오와 손실비용(시간 포함)을 줄일 수 있는 최선의 방법이다.

1974년 렌즈와 프리즘 가공으로 시작, 현재는 고난이도의 각종 비구면 생산과 대형물 가공업체로 변모한 서울광학산업(주)(대표.이지웅/www.seoulopt.co.kr)이 최근에는 총 소요비용 10억원 이상을 투자하고 4년여의 시간과 공을 들여 직경 4m급의 대형 가공기 개발에 성공했다. 가까운 일본의 경우 이보다 크고 작은 규모의 노광기 몇 대가 있긴 하나 관련 설비 구축 정도는 일본과 비교해 서울광학산업쪽이 월등하다는 평을 받을만큼 기술과 설비투자에 오랜 기간 노력을 경주해왔다.

This study estimates the technical efficiency and total factor productivity(TFP) of and analyzes the relationship between TFP and exports for Korean manufacturing companies from 2000 to 2016. Specially, TFP is decomposed into Technical Change(TC), Technical Efficiency Change (TEC), and Sale Effect(SE), and compared between large and small enterprises. First, in the case of technical efficiency, the Korean economy has been very vulnerable to external shocks, such as the sharp decline following the 2008 financial crisis. The efficiency of the electronics, automobile, and machinery sectors is low and needs to be improved. In addition, the technological efficiency of large enterprises is higher than that of SMEs in most manufacturing sub-sectors except for non-ferrous metals. In the case of TFP, most changes are due to TC, and the effective combination of labor, capital and the effect of scale have little effect, suggesting that improvement of internal structure is urgent. In addition, volatility due to the impact of the financial crisis in 2008 was much larger in SMEs than in large companies, so external economic impacts are more greater for SMEs than large enterprises. The relationship between TFP decomposition factors and exports shows that TC has a positive effect only on exports of SMEs. Therefore, in order to increase exports, in the case of SMEs, R&D support to promote technological development is needed. In the case of large companies, it is necessary to establish differentiated strategies for each export market, competitor company, and item to link efficiency and scale effect of exports.

This paper examines the influence of the portion of lead investors and investors' status on the investment performance of venture syndication. According to existing literature, multiple investors in VC syndicates can positively impact investment performance by investing both tangible and intangible resources in target companies based on market influence or high visibility. On the other hand, the presence of multiple leaders can cause conflicts in formulating and implementing investment strategy or free-riding problems or increase entry barriers for potential investors, lowering additional investment from existing investors. Therefore, we hypothesize that the relationship between proportion of lead investors and investment performance is inverted-U shape. Moreover, we predict that the status of VCs in the syndication will moderate the relationship between proportion of lead investors and investment performance since high-status actors are less likely to cooperate with or yield power to others. We tested these hypotheses using 24,677 VC syndicated investment data from 1991 to 2005 and found solid supports for the hypotheses. The findings suggest that firms need to consider relationship-based power dynamics among investors within a syndication and design effective role setting and coordination systems.

For the application of the diffusion equation, slope height and maximum slope angle are calculated from the plotted slope profile. Using denudation rate as a solution for the diffusion equation, an apparent age index can be calculated, which is the total amount of denudation through total time. Plots of slope angle versus slope height and apparent age index versus slope height are useful for determining relative or absolute ages and denudation rates. Mathematical simulation plots of slope angle versus slope height can generate equal denudation-rate lines for a given age. Mathematical simulations of slope angle versus age for a given slope height, for equal denudation-rate at a particular profile site, and for comparing to other sites having controlled ages.
