중국은 1979년부터 본격적으로 시장경제체제를 도입함으로써 급격한 경제성장을 이루었는데, 본고는 저임금과 중국정부의 적극적인 외자유치정책을 활용하기 위해 밀려들어온 외국인투자에 어떤 요인들이 영향을 미쳤는지를 검토하기 위해 1979년부터 2013년까지의 패널데이터를 이용해서 각 성·시의 고유한 특성까지 활용하는 실증분석을 시도한다. 실증분석을 위해 본고는 확률효과모형, 고정효과모형, Pooled OLS, 그리고 확률계수모형을 사용하는데, Pooled OLS와 확률계수모형의 결과는 본 연구의 분석결과와 비교를 위해서 제시된다. Hausman' test 결과 Random Effect Model보다는 Fixed Effect Model이 더 효율적인 분석결과를 제시하는 것으로 나타나 이를 근거로 중국정부에 대한 정책적 시사점을 제시한다. 분석결과는 FDI유입에 각 성·시의 지역소득수준, 자본량, 통신비는 긍정적인 영향을 미치고 고속도로는 부정적인 영향을 미치는 것으로 나타난다.

Introduction of ICE(Integrated Collaboration Environment) has a great effect on corporate performance. In particular, it is expected that information sharing and collaboration among transaction partners will be an important factor which mediates ICE and its performance. Under such a background, this research intends to identify the influence of ICE by manufacturing industry on corporate performance through role of the parameter of information sharing and collaboration. The result of this research may be summed up as follows: ICE promotes information sharing and collaboration among enterprises, it accelerates integration of supply chain network among enterprises and cooperation. In particular, ICE has a great effect on information sharing. And information sharing has a direct effect on collaboration and performance. However, when we classify corporate performance into the "performance due to introduction", which is direct performance, and the "overall performance", which is indirect performance, the result of this research is as follows: information sharing has a great effect on the performance due to introduction, but does not have a meaningful effect on indirect performance. On the other hand, collaboration does not have any effect on the performance due to introduction, but has a meaningful effect on the overall performance, which is indirect performance. It is necessary to study and analyze additional this result in future.

본 연구는 동태적 접근 방식을 이용하여, 지방 재정지출이 수질개선에 미치는 직접효과와 간접효과를 추정한다. 이를 위해 2010년부터 2018년까지 173개 시군구를 대상으로 패널자료를 구축하고, 2단계 동태패널모형을 추정한다. 실증분석 결과를 정리하면, 첫째, 수질 환경부문의 재정지출은 BOD 및 T-P 개선에 효과적인 것으로 나타났다. BOD에 비해 T-P에 대한 직접효과가 더 크게 나타났으며, 장기적으로 그 효과가 커지는 것으로 나타났다. 둘째, 수질개선을 위한 재정지출은 지역 소득에 긍정적인 영향을 미치는 것으로 나타났으며, 지역 소득과 BOD는 '역 U자형' 관계를 보였다. 수질 개선에 대한 재정지출의 평균적인 간접효과는 BOD에 대해서만 지역 경제성장 과정에서 수질을 악화시키는 것으로 나타났다. 셋째, BOD의 경우 수질개선에 대한 지방 재정지출 효과는 간접효과보다 직접효과가 컸으나, T-P의 경우 간접효과는 유의하지 않고, 직접효과에 의해서만 총효과가 결정되었다. 즉 지방 재정지출이 지역 경제성장을 통해 수질을 악화시킬 수 있지만, 수질을 직접적으로 개선하는 효과가 장·단기에 더욱 크게 나타났다.

Purpose: We explore to find out and analyze the direct influence of Millennial Orientation on Goals Mediated by work engagement and satisfaction. And, interaction cannot be a direct relationship between research variables. Method: The implementation uses the survey method. This research was conducted at PT. East Kalimantan fertilizer operated in Bontang, East Kalimantan. The population in this study were all employees of PT. East Kalimantan fertilizers operated in Bontang, as many as N = 500 people. The sampling technique used is proportional stratified random sampling. Findings: Millennial orientation influences engagement, job satisfaction and intention to leave, direct engagement has a significant effect on job satisfaction and intention to leave, and job satisfaction is directly related to intention to leave. Originality: Alignment between millennial goals in encouraging job satisfaction and employee engagement, so that it can have an impact on the intention to leave employees, especially at PT. Pupuk. Kaltim. Also, direct millennials as decreasing intention to leave.

Spot welding is one of the important welding processes for the construction of thin metal sheet. Because of low investment cost, alternating welding current is widely applied for power source. Direct current type could be, however, recommened for high quality weldment. In this study, the effect of welding current type on the weldability and the electrode life in spot welding of aluminium alloy were investigated. Various welding tests were done by using three phase direct and alternating welding current, respectively. In spite of high variation of welding force, weld quality and electrode life with alternating welding current were shown better results than those with direct current for 2mm thick alumininum alloy sheets. This was due to excessive erosion of the positive electrode in direct welding current compared with the negative one. On the contrary to 2mm sheets, the welding parameters of alternating current for 1mm sheets must be carefully selected.

This experiment was conducted to investigate the effect of floor heating system on housing environment and performance in broiler production. PVC heating pipes(in 25cm spacing) were covered with concrete under the litter. Floor heating system was compared with conventional direct heating system. Each treatment had two replicates of 110 birds each. Litter moisture content was significantly reduced in floor heating system than conventional direct heating system(P〈0.05). Dust concentration was higher in floor heating system because of low litter moisture content. CO$_2$concentration was 2,900ppm and 1,500ppm on the direct heating system and floor heating system, respectively at the age of 1 week. Body weight was significantly higher in floor heating system at 7 weeks of age(P〈0.05). The results of the trial show that floor heating was useful heating system for broiler production.

The purpose of this investigation is to carry out, the influence factor on the fuel spray characteristics for improve the engine combustion performance and exhaust omission in direct injection type diesel engine. The fuel properties, fuel spray structure and the shape or the piston surface of diesel engine play an important role of engine combustion process and exhaust emission. In order to obtain the effect of using auxiliary chamber and emulsified fuel on the fuel spray characteristics the experiment un conduct with single cylinder direct injection type diesel engine to examine the engine performance and gas emission. The results of this investigation showed that the increase auxiliary chamber volume and emulsified fuel give an effect on the fuel spray characteristics by reduced the concentration of nitric oxide emission in the combustion chamber. Also it can improve the combustion characteristics such as cylinder pressure, rate of pressure rise and rate of heat release.

We generated single-crystal organic nanowire arrays using a direct printing method (liquidbridge- mediated nanotransfer molding) that enables the simultaneous synthesis, alignment and patterning of nanowires from molecular ink solutions. Using this method, single-crystal organic nanowires can easily be synthesized by self-assembly and crystallization of organic molecules within the nanoscale channels of molds, and these nanowires can then be directly transferred to specific positions on substrates to generate nanowire arrays by a direct printing process. The position of the nanowires on complex structures is easy to adjust, because the mold is movable on the substrates before the polar liquid layer, which acts as an adhesive lubricant, is dried. Repeated application of the direct printing process can be used to produce organic nanowire-integrated electronics with twoor three-dimensional complex structures on large-area flexible substrates. This efficient manufacturing method is used to fabricate all-organic nanowire field-effect transistors that are integrated into device arrays and inverters on flexible plastic substrates.

DUP (direct underside pressurization)-장치와 프로펠러가 있는 3 차원 형상의 위그선(WIG-craft) 주위의 유동특성을 수치적으로 해석하였다. 이를 통하여 위그선 주위의 공기역학 관점의 힘들과 모멘트에 대해 고찰하였다. 이 연구의 해석에 사용된 모델은 프로펠러, 동체, 날개와 동체아래의 압력실 (air chamber)을 포함한 전 영역에 대하여 수행하였다. DUP 장치는 추력의 일부를 동체 아래의 압력실에 정체시킴으로 이륙 시와 같이 낮은 속도에도 효과적으로 양력을 증가시켜 이륙 속도를 줄이는 장치이다. 이러한 DUP 장치는 동압의 증가로 인하여 항력이 증가하고 공기의 회전성분으로 인하여 추가적인 모멘트를 생성하게 된다. 위그선의 비대칭 유동에 의해 발생하는 요잉 및 롤링 모멘트가 위그선의 안정성에 미치는 영향은 매우 미미하였다.
