  • This paper diagnose subjects and measures the learning ability of students based on the goal of developing an assessment tool for education productivity based on multi-aspect evaluation conducted by ICEE at Honam University. Furthermore, develop an assessment tool for education productivity that provides a motive to bring detailed improvements in teaching methods through the diagnosis. In addition, a method for compensating the issues and improving the quality of subject is suggested to develop learning ability of students through applying the assessment tool. An integrated operated system of CQI is desired to be built along with quality improvement of education through measuring academic quality by studying the methods for enhancing academic and learning ability achievement from analysis of the curriculum provided in the "ABEEK program". Through this study the current state of education productivity is presented through analyzing the difference between students who participated in the "ABEEK program" and who did not participate, and operating a comparison between the student's comprehension on their majors and liberal arts by the multi-aspect evaluation that has been conducted for 2 years.

  • The purpose of a business's existence is to make profit. The objective of business can be attained through the most profitable activities such as the improvement of productivity, quality and the reduction of the manufacturing cost. In order to produce the goods with above said goal, it can be achieved by inducing and improving the manufacturing process. In this viewpoint, We'd like to develope an algorithm for improving productivity, quality and cutting the manufacturing cost under the limitation of the resources. This paper showed a practical method which gradually improves three factors [productivity, quality and cost-down] by calculating the effective value of single and multi process mutually.

  • It's so difficult to obtain simultaneously both product quality and improvement of the productivity of which products are in hot aluminum extrusion process. But significant improvements in productivity and extrudate quality result from die cooling system using nitrogen gas injection during aluminum hot extrusion. These benefits are due primarily to cooling effect nitrogen gas and removal of excess heat in the extrudate temperature. This investigation is carried out hot extrusion experiment, also compared cooling system with non-cooling system to inspect cooling effects on hot aluminum extrusion. The purpose of this investigation is estimated the grain growth fur the extrudate quality, and the ram speed for the improvement of the productivity.

  • The construction industry kept lower level of the technology and productivity improvement than any other kinds of industry. But in most analysis of previous construction work which promoted the productivity of construction, the analysis process has only developed by the economical efficiency or the time studies through work sampling in construction field, So We suggest motion analysis as a tool to solve these problems. Spacially, this study find out productivity improvement method of steel frame fabrication works with using motion analysis. If the result of this study were to be applied to the actual construction field, it will be of great help for Building Construction Automation.

  • Labor productivity issues within the construction industry are receiving increasing attention. With the improvement in the standard of living, domestic laborers are avoiding 3D(Difficult, Dirty, and Dangerous) jobs by degrees. Because of this situation, the problem of insufficient labor is exacerbating in several basic industries. In particular, insufficient labor is a serious problem in the construction sector, where the workers are ageing and labor costs are increasing. In this study, we adopt a systematic approach to identify factors that influence labor productivity and analyze the causality between the factors and their ripple effects with the aim that the results of the study will help improve labor productivity and ensure its effective management. The established labor productivity model using systems thinking will get a footing in the greatest strategy in the construction industry.

  • Streptomyces cattleya is a producer of carbapenem antibiotics, thienamycin and N-acetylthienamycin, which have potent and broad-spectrum antibacterial activities. We stud ied on strain improvement for antibiotic productivity of S. cattleya by transformation technique which employed S.cattleya protoplasts and chromosomal DNAs of glutamic acid producers: Corynebacterium glutamicum and Arthrobacter simplex. 150 Transformant strains were cultured and bioassayed using Bacillus subtilis and Staphylococcus aureus as test organisms. 8.7% of transformants tested showed 1.4~2.6 fold higher productivities than wild type which produced $1.61{\pm}0.67{\mu}g/ml$. The best transformant produced $8.36{\pm}2.84{\mu}g/ml$ carbapenems.

  • Productivity is the essential comparative advantage in high tech industry company in 21 century. These company endless endeavor for low cost production. Low cost production can be led by low facility operation cost and low labor cost. But reducing facility operation cost arise much investment. Thus many high tech company drive reduction of labor cost. These article suggest model for reducing labor cost and prove a effect by example of some company.

  • 벽식 구조 공동주택(고층아파트)은 수평, 수직구조체가 동일하게 연속되므로 시스템거푸집 시공이 효율적이다. 그런데 현재 많은 고층 건축물 시공현장에서 사용되고 있는 시스템 거푸집은 전용횟수의 증대와 콘크리트 품질향상의 장점을 가지고 있지만, 공장 제작되어 현장 반입된 후 2차 조립 과정중의 공기지연 및 시공초기의 인력과다투입 등으로 초기 계획공정달성에 많은 애로점을 가지고 있다. 이러한 측면에서, 각각의 노무자들이 실제 생산적인 작업에 소비하는 시간 비율과 공사지연의 정도 및 원인 등을 평가대상으로 생산성 저하의 원인을 찾아내어 개선방안을 찾아보고자 한다. 본 연구는 시스템거푸집 공정을 수행하고 있는 아파트 신축현장을 선택하여, 다양한 생산성 분석방법 중의 하나인 워크샘플링(Work Sampling)를 통하여 생산성을 분석한 후, 크루발런스스터디(Crew Balance Study)를 통하여 생산성 향상방안을 현장조립공정과 내부 폼(form)작업, 외부 폼(form)작업으로 구분하여 제시하였다.

  • This study has analyzed the efficiency of 10 leading global shipping companies listed in the New York Stock Exchange from2010 to 2014 in order to find the changes of the productivity of shipping industry. The paper observed the Malmquist Productivity Index by using Efficiency and Productivity Analysis System Version 1.0. The data used in this study is the Guggenheim Shipping ETF mainly including the companies of shipping, management, and shipbuilding areas. The results from this statistical analysis indicate that the 10 selected companies have experienced a severely negative growth in 2010. Nevertheless, these companies have accomplished a significant growth of productivity. In particular, the energy transport companies operating Tanker and LNG ships carried out remarkable growth. The reason why the productivity of liner shipping companies did not show the improvement of productivity for five years was attributed to the fact that the P3(Project 3) or M2(Maersk-MSC) including Maersk, MSC, and CMA-CGM were excluded in this research because of the difficulty of attaining reliable source data. The method of this study could be extended to Korean shipping corporations and other global airlines to investigate a changes of certain industries.
