본 연구는 경부고속철도 공사에 처음으로 적용한 PSM 공법의 현장사례 분석을 통하여 생산성 향상 방안을 모색하였다. 본 사례현장의 경우 생산성에 영향을 많이 미치는 요인으로는 기능공의 숙련도 미숙, 장비운영관리 미흡 동절기 콘크리트 양생 조건 등을 발견하였다. 따라서 생산성을 향상시키는 방안으로 기능공들의 숙련도 중진, 생산성 향상을 위한 인센티브제도의 도입, 관계자간의 긴밀한 협조, 조직적인 팀웍, 생산적인 작업 여건 조성 둥을 제시하였다. 이외에도 생산성 향상을 위한 방안으로는 수행한 작업에 대한 철저한 피드백으로 작업방법의 지속적인 개선, 현장여건에 맞는 지속적인 교육훈련 등이 필요하다. 이러한 생산성 향상 방안을 활용하여 향후 적용될 공사에 있어 PSM공법의 장점을 최대한 살려, 성공적인 공사 수행을 도모하고자 한다.

It is very important moments to look revolutionary changes on the whole industries in the upcoming new millennium. Traditionally, packaging was differentiated from design, production, and quality test in improving productivity. Therefore packaging concept should be updated as the time changes. For the productivity improvement, Packaging should be regarded as the value added goods and changed with leading edge technologies to meet various market needs due to its complex faces based on econo-environmental nature.

Constructing high buildings is a global trend, and skyscrapers for residing are also increasing. But a period of works for finish construction is different depending on a company while a period of works for frame construction of skyscrapers for residing in the country is regular when considering a difference of a method of construction, and the increase of repeated construction for high buildings and number of related process for finish construction are stressing the importance of improving productivity through construction management and plan for works. Because there are many compositive factors affecting productivity other than technical factors, we should intensively study the way of improvement and prevention preferentially through analyzing factors affecting productivity. So in this study, we present important management factors for making systematic strategy and plan for improvement of productivity by finding factors affecting productivity depending on the degree of importance unifying factors affecting productivity of plan factor(internal factor of construction process) and management factor(outer factor of construction process).

The purpose of this study is to execute the investigation of injurious factors causing muscle-skeletal diseases at an automotive glass manufacturing company and, on the basis of the results, to enhance productivity by the improvement of working environment. By using an survey and an ergonomic evaluation method, symptoms of muscle-skeletal diseases of workers and working postures at each process were analyzed, and quantitative evaluation of muscle-skeletal disease risk against each process was performed. Based on the result of the evaluation, to enhance the working environment, improvement of worktable, working space, tools, and outfit was suggested, and induction of mechanical system was also suggested. Suggested improvement plan was applied to the workplace step by step and it is confirmed that improvement plan not only removes the injurious factors of muscle-skeletal diseases but also is effective to enhance productivity.

This study presents the results of our analysis and recommendations for process and productivity improvements. The project studied consists of a 5-story research building, with a structure of steel frames supporting concrete slabs. The observations focused on the analysis of the overall erection and framing process. The methods used for the analysis consisted in intensive visits on site, where construction processes were observed in term of resources, activities, durations, materials' handling procedures, and technology used. Back to the office, authors used the information captured to model the different trades' activities, using work sampling and 5-minute rating technique. The work sampling provides insight into the activity, hence allowing for process improvements. The productivity of various trades is strongly dependent on the organization of the work process and work site conditions. Improving the productivity of the entire project or company is not possible until everyone is committed to improvement.

The project was undertaken to provide information on the present system of traditional pig farming in the South Pacific region, to identify the problems currently limiting productivity of such pigs and to offer practical strategies which could be used for increasing productivity of the animals. The problems were identified by surveying some 220 subsistence pig farms in eleven island countries in the South Pacific region using a prepared questionnaire. The units were found to be generally small, consisting of about 2-4 sows per herd. The productivity of the units as assessed in terms of sow reproductive efficiency was rather low, being only about 7.5. Feed, housing, breeding, disease, marketing, lack of capital, technical know-how and existing social traditions were identified as current constraints. Based on three of the most limiting factors identified namely feed, housing and breeding, strategies for improvement were developed on the basis of better and more effective use of locally available feed resources, better housing and genetic improvement through crossbreeding programmes. These improvement strategies were tested as a package model on some ten farms in two of the island countries. The results of these on-farm trials indicated that using the improvement strategies increased sow reproductive efficiency by approximately 60 percent, to nearly 12. The significance of these findings in the overall management of traditionally raised pigs in the South Pacific region is discussed.

This study deals with the procedure of safety improvement, productivity increase ,and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind ,the necessity ,and the concept of preventive maintenance ,and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss ,comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.

본 연구는 충남 서부지역 근로자의 현장훈련교육이 생산성 향상에 미치는 영향을 분석하였다. 한국폴리텍대학 교육 및 노동부 지원 현장교육과정을 수료한 충남 서부지역 근로자를 대상으로 설문지 총 76부를 분석하였다. 연구결과 첫째, 근로자의 현장훈련교육이 생산성 향상에는 현장훈련교육을 받게 된 동기가 높을수록 교육만족도가 향상되는 것으로 나타났으나 직무생산성에는 유의한 영향이 미치지 못했다. 둘째, 훈련경험이 직무생산성과의 상관관계는 통계적으로 유의한 영향을 미치지 못한 것으로 나타났다. 셋째, 직급에 따른 생산성 향상에 미치는 영향으로는 임시직이 평사원(대리급)보다 교육만족도가 높은 것으로 나타났고, 직무생산성은 중간관리자(과.차장급)보다 관리자(부장급)이상이 가장 높게 분석되었다. ANOVA 분석 결과에서는 근무년수, 경력, 직급에 따라 교육만족도, 직무만족도에 유의한 영향을 미치는 것으로 분석되었다. 본 연구는 충남 서부지역 근로자의 현장교육훈련이 생산성 향상에 미치는 영향을 분석함으로써 교육만족도, 직무생산성 향상에 대한 근로자 개인의 훈련경험 및 훈련동기에 대한 특성 요인의 중요도를 파악하고 근로자의 개인적 요인의 효과성을 검증한 데 연구의 의의가 있다.
