온실가스 저감정책이 시행되면 에너지 다소비 제조업은 비용 상승으로 인해 많은 영향을 받을 것이다. 그러나 가격설정력이 있는 산업이라면, 비용 상승을 제품 가격의 상승을 통해 소비자에게 전가시킬 것이므로 온실가스 저감정책으로 인한 피해가 적을 것이다. 따라서 본 연구는 에너지 다소비 제조업의 가격설정력을 분석함으로써, 각 산업이 온실가스 저감정책에 얼마나 취약한지 살펴보았다. 본 연구에서 사용한 가격설정력모형은 오차수정모형을 통하여 분석하였으며, 수입재의 가격과 인건비를 주요한 설명변수로 사용하였다. 수입재의 가격에 반응을 한다면 경쟁자의 가격에 따라 가격을 설정하는 가격 순응자로 볼 수 있으며, 이러한 산업은 온실가스 저감정책에 취약할 것이다. 반면에, 국내 비용을 의미하는 인건비에 영향을 받는다면, 가격설정력이 있다고 볼 수 있으며, 온실가스 저감정책에 덜 취약할 것이다. 또한, 에너지 가격의 변동은 우리나라 뿐만 아니라 해외에도 영향을 미치므로 수입재의 가격에 반영이 되어 있을 것이다. 따라서 수입재의 가격의 순영향을 보기 위해 에너지 가격을 통제변수로 사용하였다. 추정 결과, 석유제품, 화학제품, 비금속 광물제품, 섬유제품, 자동차 제조업은 가격설정력이 있는 것으로 분석되었으므로, 이들 산업은 온실가스 저감정책에 대해 경쟁력을 가지고 있다고 볼 수 있다.

This study examines the relationships between R&D investment and Market value of Firms using data of small and medium enterprises (SMEs) in the manufacturing sector of Korea. In particular, this paper investigates the role of technology innovation system in the impact of R&D investment on firm's Market value of Firms. Findings from the previous studies on the relationship between R&D investment and Market value of Firms are positive relationship. Main of the previous studies demonstrated a positive impact of R&D investment on Market value of Firms. On the other hand, some recent studies showed this is not the case. Those studies persisted that the technological innovation system for managing and efficiently utilizing R&D investment and capability has to be built in order for R&D investment to give rise to increases in Market value of Firms. According to the Oslo manual by OECD, it is assumed that a technology innovation system can becharacterized as three factors :capability for technological innovation, capability for technology commercialization, capability for technological innovation management. This study divides sample firms into two groups using the "Inno-Biz" certificate system of the Korean Small and Medium Business Administration (SMBA): Inno-Biz firms Vs. Not Inno-Biz firms. The system selects innovative SMEs denoted as "Inno-Biz" using the above factors as criteria. The results revealed that the technology innovation system has the moderating effect to R&D investment on Market value of Firms.

Engineering is a sector with more than three times the industrial effectiveness of manufacturing. In the domestic engineering life cycle, the Operations & Maintenance (O&M) phase is a relatively high level of technology. Based on accumulated knowledge of O&M phase, it is necessary to advance operating technology and expand overseas O&M market expenditure. This study is the early stage of knowledge-based power plant O&M service framework reference model. In this study, we propose a conceptual model of architecture framework for power plant O&M. We survey the architecture framework and reference model and propose conceptual model of architecture framework for power plant O&M. The conceptual model of architecture framework for power plant O&M consists of stakeholder, O&M scenario, O&M technology. In particular, the O&M technology is defined as the fourth industrial revolution intelligence information technology. We defined a meta model from the conceptual model to define the power plant O&M architecture framework. In the future, we intend to development an architecture framework from the conceptual model and meta model.

Compact Near Infrared Diode Array Spectrometers offer new possibilities for on line quality assurance in the agricultural sector. Due to their speed and complete robustness towards temperature fluctuations and mechanical shock Diode Array Spectrometers are suitable for the use on Agricultural Harvest Machines. The growing consumer consciousness of food quality in combination with falling manufacturing prices demands procedures for an effective quality control system. The various conventional types of NIR instruments which have so far been used in laboratories are unsuitable for mobile applications under the rough conditions of field cropping not only because of their slow speed of measurement but also because of their shock sensitive filter wheels and monochromators necessary for fractionating polychromatic light. Another advantage of the on line use is the reduction of the sampling error because of the continuously measurement of the whole product. Considering the large economic importance of the dry matter content on agricultural products it is of particular advantage that water belongs to those constituents which are most easily assessed in the near infrared. While other constituents of economic importance such as starch, oil and protein in grains and seeds have a much lesser effect on NIR signals, their contents can nonetheless be assessed with high analytical precision on freshly harvested grains and seeds. In the last years several applications for on line quality assessment on harvesting machines were developed and tested. The talk will give an overview and outlook on existing and future possibilities of this new field of NIR applications.

With the diffusion of the Internet, firms try to electronically collaborate with their partners in order to cut costs and gain profits. This, electronic Partnership, called 'Collaborative IT' is quite popular between large purchase enterprises and small-to-medium sized sub-contractors. This study investigates such relations. This study proposes three groups of research variables-interorganizational relationship, collaborative IT activity, and firm performance. the interorganizational relationship consists of trust, commitment, and asymmetry of commitment. Collaborative IT activity is composed of information sharing and workflow integration. The ultimate dependent variable is firm performance. It is hypothesized that the relationship factors influence the level of collaborative IT activity, while the latter in turn affects the firm performance. The relationship factors nay also directly affect the dependent variable. In addition, collaborative IT motive, as a moderating variable, may influence the causal relationship. By means of survey, ore hundred and eighty-two responses were obtained. Most sample companies are small-sized, in the manufacturing sector. The analysis of data reveals that both trust and commitment positively affects the level of collaborative IT activity, while asymmetry of commitment has negative effects. The workflow integration is significantly related with firm performance. Information sharing, however, has no signific3nt effects. Furthermore, asymmetry of commitment shows reverse relationship with firm performance. Collaborative IT motive works as a moderating variable between information sharing and firm performance. Finally, workflow integration is believed to mediate between relationship factors and firm performance.

This study examines health and life satisfaction of the married female production workers(Mfpw). The data of 370 Mfpw in manufacturing sector in Taegu are collected by using questionares in August, 1995. Health scale measured by Todai Health Index is composed physical health and mental health. There are three satifsfaction areas-individual life satisfaction, family life satisfaction, and job satisfaction-in the overall life satisfaction scale. The findings of this study are as follows: 1) Mfpw’s total health conditions are poor. Especially physical health is worse than mental health. Physical health is influenced by age and purpose of attaining job, while mental health is influenced by purpose of attaining job. Mfpw who get the job for family financial needs have poor physical and mental health. 2) The overall life satisfaction level of Mfpw is lower than middle point : their family life satisfaction level is the heigest and their individual life satisfaction level is the lowest. Family income, purpose of attaining job and work place environment have effect on the level of overall life satisfaction. Mfpw who have the higher family income, get the job by non-economic motivations and work in good work place environment show the higher life satisfaction level.

The fisheries industry has led the Korean economy, and has been achieving high-level position in the world. However, this industry meets aging, low growth and profit. In order to overcome this critical situation, it is needed to understand the overall status of industry. In industry level, most of previous researches focused on ocean industry rather than fisheries. In addition, scholars have been getting a lot of attention about fisheries cooperatives, fishing-ports, methods of fishery, and manufacturing process in fisheries sector. The aim of this research is analysis of domestic fisheries industry's managerial performance using data envelopment analysis(DEA) considering operating and scale view. Furthermore, the comparative analysis is performed by firm size, and industry type. In results, fisheries industry's managerial performance is not high, overall. In more detail, most of big size firms are under decreasing returns to scale(DRS) status. Fishery processing industry's performance is low, and fishery distribution industry has the best performance. This paper suggests that transferring operating capability from big firms to small firms, and policy supports and firm's activities should be accompanied for high-value added in fisher, and fishery processing industries.
