The engineering industry plays an important role for national competitive, since it has an high impact on other industries. With its importance, the engineering industry development largely depends on its technical manpower ather than capital factor. This study aims at estimating the additional requirement on technical manpower based on the forecasted market size which represents the structure change corresponding to economic growth in related industry. Research scope includes the twelve of fifteen field except three with insufficient historical data and technical manpower above bachelor degree. Specialty, we forecast market size with determinants resulted from historical data analysis on each field. The demand on technical manpower is derived from the forecasted market. We also estimate an additional requirement with the supply analysis. The research results show different patterns over time period. The relative ratio on chemical and construction to total market will steadily grow over short term, while applied, environment, electronic and information will rapidly grow This pattern will be stabilized over mid or long term. The additional requirement on technical manpower represents the similar pattern to market growth. The research result implies manpower policy for having high inflow of technical engineer from educational institute and the related industries through the image improvement.

Deteriorating soil physical properties and increasing soil pathogens due to the continuous cultivation of field crops are the leading causes of productivity deterioration. Crop rotation, soil heat treatment, and chemical control are used as pest control methods; however, each has limitations in wide application to domestic agriculture. In particular, chemical control requires improvement due to direct exposure to sterilizing solution, odor, and high-intensity work. To improve the overall domestic agricultural environment, the problems of time and cost, such as field maintenance and cultivation scale, must be addressed; therefore, mechanization technology for chemical control must be secured to derive improvement effects in a short period. Most related studies are focused on the control effect of the DMDS (dimethyl disulfide) sterilizer, and research on the performance of the sterilization spray device has been conducted after its introduction in Korea, but research on the corrosion suitability of the material is lacking. This study conducted a corrosion test to secure the corrosion resistance of a soil sterilizer injection pump, and a mechanical failure mode by corrosion by the material was established. The corrosion test comprised operation and neglect tests in which the sterilizing solution was circulated in the pump and remained in the pump, respectively. As a result of the corrosion test, damage occurred due to the weakening of the mechanical strength of the graphite material, and corrosion resistance to aluminum, stainless steel, fluororubber, and PPS (polyphenylene sulfide) materials was confirmed.

Estimation of hydraulic parameters is a critical step during design of foundation dewatering works. When many piles are installed in an aquifer, estimation of the hydraulic conductivity should consider the blocking of groundwater seepage by the piles. Based on field observations during a dewatering project in Shanghai, hydraulic conductivities are back-calculated using a numerical model considering the actual position of each pile. However, it is difficult to apply the aforementioned model directly in field due to requirement to input each pile geometry into the model. To develop a simple numerical model and find the optimal hydraulic conductivity, three scenarios are examined, in which the soil mass containing the piles is considered to be a uniform porous media. In these three scenarios, different sub-regions with different hydraulic conductivities, based on either automatic inverted calculation, or on effective medium theory (EMT), are established. The results indicate that the error, in the case which determines the hydraulic conductivity based on EMT, is less than that determined in the automatic inversion case. With the application of EMT, only the hydraulic conductivity of the soil outside the pit should be inverted. The soil inside the pit with its piles is divided into sub-regions with different hydraulic conductivities, and the hydraulic conductivity is calculated according to the volume ratio of the piles. Thus, the use of EMT in numerical modelling makes it easier to consider the effect of piles installed in an aquifer.

Literature review through academic journals, survey research and the FGI(Focus Group Interview) were used to accomplish objectives of the study. In addition, the survey research and FGI were done for professors. For the survey research, nationally 20 out of 44 universities which operates the CAC program were investigated, and sample universities were considered by region. FGI was done to analyze the performance and problems of CAC in more detail for 6 experts. Results of the study were follows as; first, CAC program was activated through the Seoul Accord activation support business by government. Second, BSM(Basic Science and Math), engineering major and engineering design education have been strengthened compared with before and after of CAC introduction in the computing engineering field. Third, soft skills needed for students in the college of engineering have been organized in the professional general curriculum, and professors aware of improvement of ability of the students for the skills.

In this article, the dynamic fracture instability characteristics, including dynamic crack propagation and crack branching, in PMMA brittle solids under dynamic loading are investigated using the discrete element method (DEM) simulations. The microscopic parameters in DEM are first calibrated using the comparison with the previous experimental results not only in the field of qualitative analysis, but also in the field of quantitative analysis. The calibrating process illustrates that the selected microscopic parameters in DEM are suitable to effectively and accurately simulate dynamic fracture process in PMMA brittle solids subjected to dynamic loads. The typical dynamic fracture behaviors of solids under dynamic loading are then reproduced by DEM. Compared with the previous experimental and numerical results, the present numerical results are in good agreement with the existing ones not only in the field of qualitative analysis, but also in the field of quantitative analysis. Furthermore, effects of dynamic loading magnitude, offset distance of the initial crack and initial crack length on dynamic fracture behaviors are numerically discussed.

본 연구는 스마트팩토리 도입의도에 영향을 미치는 요인을 실증 분석을 통해 확인하였다. 4차산업혁명의 핵심분야인 스마트팩토리 도입에 있어서 어떤 요인이 중요하게 영향을 미치는가에 대한 연구이며, 아직까지 스마트팩토리 분야에서 기술 수용에 관한 연구가 부족한 상황에서 학술적 실무적 의의가 있다고 믿는다. 정보기술의 수용요인 연구에 설명력이 검증된 통합기술수용이론(UTAUT)을 기반으로 연구를 진행하였으며, UTAUT 이론의 4가지 독립변수인 성과기대, 노력기대, 사회적영향, 촉진조건에 추가로 스마트팩토리의 특성상 중요한 요인으로 예상되는 정부지원기대(Government Assistance Expectancy)를 독립변수에 추가하였다. 또한 스마트팩토리 기술수용의 기술적인 요인을 확인하고자 과업기술적합도(Task Technology Fit)변수 추가하여 스마트팩토리 도입의도에 미치는 영향관계를 실증 분석하였다. 또한 과업기술적합도의 선행변수인 과업특성(Task Characteristics)과 기술특성(Technology Characteristics)이 과업기술적합도에 어떠한 영향을 미치는지에 대한 분석도 진행하였다. 새로운 기술에 대한 신뢰(Trust)의 정도가 기술의 수용에 있어 매우 중요한 영향을 미칠 것으로 예상되어 신뢰를 매개변수로 추가하였다. 마지막으로 새로운 정보기술에 의한 혁신이 사용자에게 불가피하게 거부감을 야기할 수 있다는 선행연구들을 토대로 혁신저항(Innovation Resistance)을 조절역할을 하는 연구변수에 추가하여 실증적 검증을 진행하였다. 연구 결과 성과기대, 사회적 영향, 정부지원기대, 과업기술적합도는 스마트팩토리 도입의도에 정(+)의 영향을 미쳤다. 영향력의 크기는 정부지원기대(β=.487) > 과업기술적합도(β=.218) > 성과기대(β=.205) > 사회적영향(β=.204) 순으로 나타났다. 과업특성과 기술특성은 모두 과업기술적합도에 정(+)의 영향이 확인되었으며, 과업특성(β=.559)이 기술특성(β=.328)보다 과업기술적합도에 더 영향이 큰 것으로 나타났다. 신뢰에 대한 매개 효과 검정에서 6개 독립변수 각각과 스마트팩토리 도입의도 간에 신뢰의 통계적으로 유의미한 매개역할은 확인되지 않았다. 혁신저항의 조절효과 검정을 통해, 혁신저항이 정부지원기대와 스마트팩토리 도입의도 간 정(+)의 조절역할을 하는 것으로 나타났다. 즉 혁신저항이 크면 클수록 정부지원기대가 스마트팩토리 도입의도에 미치는 영향력이 혁신저항이 적은 경우보다 커지는 것으로 나타났다.

본 연구는 업종별 혁신체제론의 입장에서 한의학산업을 보지만, 한의학산업의 혁신체제 자체가 아니라 혁신체제에 가장 큰 영향을 미치고 있는 요인인 서양의학과의 갈등을 중심으로 살펴 본 것이다. 한국의 의료시스템은 서양의학과 한의학을 이분법 체계로 구분함에도 한의학과 서양의학의 의료행위에 대한 명확한 정의를 하지 않고 있다. 이에 따라 판례로 두 의학이 구분되는데, 의료시스템에서도 또한 약제시스템에서도 서양의학의 의료행위를 너무 강하게 설정해 한의학의 혁신을 저해하고 있다. 한의학산업에서는 첫째, 현대 의공학의 발전으로부터 도출된 대부분의 의료기기를 사용할 수 없다. 이 의료기기들은 대부분 서양의학의 학문적 뿌리에 기원하고 있다는 판단에서이다. 둘째로, 한의학적인 기반을 가지고 개발된 천연물 신약도 허가를 받는 순간 한의학산업에서는 처방할 수 없다. 셋째로, 한의학 기반 약제가 가진 안전성 문제는 약재 자체의 오염문제가 있고, 처방된 한약의 간 독성 문제가 있다. 전자는 재배과정이나 수입과정에서의 품질 및 안전검사로 해결될 문제이지만 후자는 서양의학쪽의 일방적인 매도라는 것이 한의계의 지적이다.
