본 논문의 목적은 서울과 부산을 대상으로 제조업과 서비스업의 상호 연관성 실태를 분석하고 이의 시사점을 도출하는 것이다. 본 논문에서는 투입산출계수와 생산유발계수를 통해 제조업에 대한 서비스업의 연관성과 서비스업에 대한 제조업의 연관성을 각각 분석하였다. 분석결과, 서울의 주력 제조업인 소비재는 서비스업과의 연관성이 상대적으로 높은 반면 부산의 주력 제조업인 조립가공은 서비스업과의 연관성이 상대적으로 낮아 제조업에 대한 서비스업의 연관성은 서울이 부산보다 높은 것으로 나타났다. 둘째, 제조업 생산과정에 투입되는 서비스업의 자기지역 의존비율이 서울은 72.0% 이지만 부산은 49.0%로 낮아, 부산 제조업의 성장이 전산업에 미치는 효과가 제한적인 것으로 분석되었다. 셋째, 서비스업에 대한 제조업의 연관성은 전반적으로 부산이 서울보다 높은 것으로 나타났다. 마지막으로 분석결과를 바탕으로 제조업과 서비스업의 상호 연관성 제고를 위한 정책방향을 제시하였다.

Project Management Information System (PMIS) is a special purpose information system that is created to provide useful information for project managers and participants to make effective and efficient decision making during projects. The use of PMIS is increasing in project based industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project management performance. However, it is unclear what are the difference of PMIS impacts between industries, and still need to be studied further. The purpose of this study is to compare the impact of PMIS on project management performance between industries. We assume that the effects of PMIS will be different depending on the industry types. Five hypotheses are established and tested by using statistical methods. Data were collected by using a survey questionnaire from those people who had experience of using PMIS in various project related industries such as construction, defense, manufacturing, software development and telecommunication. The survey questionnaire consists of 5 point scale items and were distributed through e-mails and google drive network. A total of 181 responses were collected, and 137 were used for analysis after excluding those responses with missing items. Statistical techniques such as factor analysis and multiple regression are used to analyze the data. Summarizing the results, it is found that the impacts of PMIS quality on the PM performance are different depending on the industry types where PMIS is used. System quality seems to be more important for improving the PM performance in construction industry while information quality seems more important for manufacturing industry. As for the ICT and R&D industries, PMIS seems to have relatively lesser impact compared to construction and manufacturing industries.

Today's manufacturing industry is facing challenges from advanced difficult-to-machine materials (WC-Co alloys, ceramics, and composites), stringent design requirements (high precision, complex shapes, and high surface quality), and machining costs. Advanced materials play an increasingly important role in modem manufacturing industries, especially, in aircraft, automobile, tool, die and mold making industries. The greatly-improved thermal, chemical, and mechanical properties of the material (such as improved strength, heat resistance, wear resistance, and corrosion resistance), while having yielded enormous economic benefits to manufacturing industries through improved product performance and product design, are making traditional machining processes unable to machine them or unable to machine them economically. In this paper, mechanical characteristic evaluation test of fine powder type WC-Co alloy was accomplished to obtain clear data for miniaturized special die parts machining with high reliability and high quality.

This study concerns with the accident characteristics and prevention in small manufacturing industries of chemical products. To investigate the accident characteristics, we used workers' compensation reports and employers' accident analysis reports. One hundred and seven injury accidents which results in more than 4 days absence were surveyed from the manufacturing companies with under 100 employees. These data were used to investigate the accident characteristics in terms of company size, injured person's age, work experience, accident time, activity at time of accident, accident type, injury type, injured body Part, and accident agency We propose the accident prevention policy based on the accident characteristics. These results can be used to develop more effective occupational safety management policies in small manufacturing industries of chemical products.

By the mid 1960's the rate of productivity growth in the manufacturing industries of the United States reached the lowest level ever recorded in the American economy. As a result the cost-offsetting operations that had been a century-long part of cost minimizing became less feasible. U.S. manufacturing firins apparently embarked on a pattern of a cost pass-along management. Accounting for price variation as a function of a shift from cost minimizing to cost pass-along is the main subject of this investigation. An econometric model of the inflation process is presented which indicates a clear shift in the modal behavior of manufacturing industries from cost minimizing (1948-1964) to cost pass-along (1965-1975). The latter behavior, initially triggered by the drag of resource diversion on the productivity growth process, undermines the pressure toward productive efficiency that is at the core of industrial engineering, and at the center of U.S. industry's ability to remain competitive.

본 논문은 자기회귀시차(ARDL) 모형으로부터 도출된 오차수정모형을 이용하여 8개 제조 산업을 대상으로 수출의 임금탄력도, 수출의 이자율탄력도 그리고 수출의 수입물가지수 탄력도를 추정함으로서 생산요소가격의 변동이 수출성과에 미치는 효과를 산업별로 분석하였다. 실증분석결과를 요약하면 다음과 같다. 수출의 임금탄력도, 이자율탄력도, 그리고 수입물가지수 탄력도의 부호는 모두 대부분의 제조 산업에서 1%의 통계적 유의 수준에서 기대부호대로 음(-)으로 나타났다. 그리고 자본집약도가 큰 산업일수록 임금탄력도가 작게 나타났으며 다른 한편 해외수입중간재 비중이 높은 산업일수록 수입물가지수 탄력도가 크게 나타나는 경향을 보이고 있다. 따라서 실증분석 결과는 외환위기 이후에 이자율의 하락, 수입물가지수의 증가율 하락, 그리고 실질임금 증가율의 둔화 등으로 나타난 생산요소가격의 하락현상은 제조산업의 수출성과에 지대한 영향을 주었음을 입증하고 있다.

This paper describes the design and implementation of a low cost inertial navigation system(INS) using an inertial measurement unit(IMU), a digital compass, GPS, and an embedded system. The system has been developed for a transporter that load and unload ship blocks in a shipbuilding yard. When the transporter would move from place to place, they would periodically pass under obstructions that would obscure the GPS signal. This increases the error when estimating the position. Thus the INS has been used to improve position accuracy. INS is also capable of providing continuous estimates of the transporter's position and orientation. Even though IMU is typically very expensive, this INS is made of "low cost" components and the indirect Kalman filtering algorithm.

This paper studies the supply and demand of Industrial Technology Labor-force(ITL) and analyzes the determinate of ITL shortage in Korean manufacturing. We classified the industry into four categories-high technology industries, medium-high technology industries, medium-low technology industries and low technology industries-based on its R&D intensity like OECD. For the empirical analyses we use a survey data collected from 5,703 enterprises. The key findings are as follows: Firstly, a large majority of ITL is engaged in more technology-intensive industries but the categories that are exposed to more serious labor-force shortage problem are medium-high technology industries and low technology industries. Secondly, in the terms of supply factor, the ITL shortage problems are mainly due to the avoidance of ITL jobs. And the demand point, the reason is that the most of ITL are not researchers but production managers. Thirdly, the cause of imbalance between supply and demand of ITL are different by the technological categories. For example, in the high technology industries, the supply factors, such as average wage and turnover rate played more important role in the imbalance. But in the low technology industries the demand factors, such as per capita sales and the ratio of ITL in all employees were relatively much more important. Based on the findings, we discovered some political meanings such as the necessity to plan various policies to resolve the shortage problem of ITL according to the technological categories, etc.
