In machining to CFRP material has many important problems, about necessary of high-precision machining, improvement of tool life and dispose of cutting chips etc. Especially in case of twist drill almost cant collect under 0.5 μm cutting chip, the fine-cutting chips diffuse into the sliding table and spindle head with the machine. Moreover, the fine-cutting chip is mixed and diffuse into the atmosphere. The possibility to remarkable decline of working efficiency so the dust-collection provision technology is wished. It is important also from the viewpoint of keep safety of a worker and work environment preservation because the CFRP utilizes in market for industrial structure materials, is increasing. As one method of solving this problem which aspirates and ejects cutting chip from a penetration hole through outside in the central part of the drill shank the new tool and cyclone type dust-collection system were developed. These technologies were used for perforate of CFRP material, and investigated about the cutting characteristic of the hollow type drill, and the effect of work environment improvement to dust-collection performance of cutting chips. As the result, our development machine tool and cutting tool can collect approximate 99.5% cutting chip.

Background. In this era of Information Communication Technology, a high-quality working environment is essential to the occupants. Providing quantity rather the quality of work environments is very common in most of the least developed countries, including Tanzania. Existing research asserts that poor indoor environmental quality such as lighting has a detrimental effect on human health, and in case of the office working population, it also affects their work performance. This study aims to analyze the effects of the lighting quality on working efficiency of workers in Tanzania. Methods. Four representative offices from the administration building at Mbeya University of Science and Technology were investigated from June to September 2018. The customized questionnaire survey tool was administered to the randomly selected occupants to survey their perceptions about the quality of lighting in their workplace and its influence on their health and work efficiency. Physical observation and illuminance distribution measurements were also conducted. Results. The statistical analysis indicates that the majority of the occupants are less satisfied with the lighting quality in their working environment, and some respondents reported that it significantly affected their work efficiency and wellbeing. The average desk illuminance and uniformity level were found to be below the recommended values of the Chartered Institution of Building Services Engineers (CIBSE) and the International Commission on lighting (CIE). Conclusion. Despite the suggested improvement measures, this research emphasizes that poorly articulated work environment can adversely affect the productivity and work efficiency of the workers. The workers in such condition are also exposed to occupational diseases. Thus, providing a healthy work environment should be a fundamental right of the workers.

Employee performance is something that is considered important for the company. Employees have high performance will certainly be able to work optimally so that the objectives of the institution itself will be easily achieved. Through the improvement of the working environment and working discipline expected the resulting performance can be optimized within the enterprise. In this study to determine the three variables that can affect employee performance (Y), the work environment variables (X1) and discipline (X2). Simultaneous and partially on the performance of employees at PT.Fuji Seimitsu Indonesia. Type of research is quantitative research. Methods of data collection using questionnaires with sempel amount of research is 100 respondents.Data analysis techniques in research using descriptive analysis, multiple linear regression analysis, validity and reliability test and partial test ( Test T) and a simultaneous test (Test F). Results of research conducted using SPSS 2.2 (ststitical program for social science), from the results obtained that the working environment (X1) were significant influence on employee performance (Y) on PT.Fuji Seimitsu Indonesia because work environment variables t = 3.231 > t table 1.660 with sig = 0.002 < 0.05. Labor discipline (X2) have a significant effect on employee performance (Y). Work environment (X1) and discipline (X2) simultaneously significant effect on employee performance (Y) PT. Fuji Seimitsu Indonesia.The results obtained on the whole of the working environment (X1) and discipline (X2) are all very significant influence on employee performance (Y) in PT.Fuji Seimitsu Indonesia. Keywords:Work Environment, Work Discipline and Employee Performance

The purpose of this study is to test partially and simultaneously the influence of motivation and work environment on the performance of state civil apparatus in the Office of Integrated Service Investment and Industry of Padang Pariaman Regency, data collected by spreading the questionnaire directly. Test of research instrument used is test of validity and reliability test. The classical assumption test used is normality test, linearity test, multicollinearity test, and heteroscedasticity test. As for hypothesis test used t test and test f. The analytical method used to test the effect of motivation and work environment on the performance of civil state apparatus is multiple linear regression with the help of SPSS. The result of the research shows that there is a significant influence between the working environment on the performance of civil apparatus of the State. Simultaneously or jointly motivation and work environment significantly influence the performance of civil apparatus of the State. Based on the research, it can be concluded that motivation has a significant effect on the performance of the State Civil Apparatus on the Integrated Service and Investment Service Department (DPMPTP) of Kabupaten Padang Pariaman. The work environment has a significant effect on the performance of the State Civil Apparatus on the Integrated Service and Industrial Service Investment Service (DPMPTP) of Padang Kabupaten Pariaman. Morality and work environment have a significant effect on the performance of State Civil Apparatus at the Department of Investment of Integrated Services and Industry (DPMPTP) of Kabupaten Padang Pariaman.

This paper presents a mathematical method to analyze the influence of each machine tool part deformation on the machining accuracy. Taking a 3-axis machine tool as an example, this paper divides the machine tool into the cutting tool sub-system and workpiece sub-system. Taking the deformation of lower surface of the machine bed as the research target, the mathematical model of the deformation on the displacement of the cutting point was established. In order to distribute the stiffness of each part, the contribution degree of each part on the machining accuracy was analyzed. Using this mathematical model, the stiffness of each part can be distributed at the design stage of the machine tool, and the machining accuracy of the machine tool can be improved economically.

In this study, an analysis of independent studies dealing with occupational safety training in different learning environments, in which various learning materials are used, was carried out. As a method, meta-analysis method was used. For this purpose, databases were used to collect national and international articles and papers suitable for the purpose of the study. Studies that did not mention the tools, equipment and environment used in education in the collected studies were excluded from the research, and 18 studies were included in the meta-analysis. The data obtained studies are categorized according to the education models, the sectors in which the education is applied and the characteristics of the participants in the education. As it is known, occupational health and safety procedures aim at a healthy and reliable working environment for its employees. However, the ultimate goal is to raise not only employees but also future generations with this awareness. The most important instrument of this is undoubtedly education. For this reason, it is necessary to develop training models suitable for the work environment, age, gender and every conceivable situation.
