As one of methodological approaches for objective and systematic evaluation for rural resources, a sequential system for significance determination of resources items was formulated using AHP (Analytic Hierarchy Process) as the base technique. By the system constructed in this study, the significance values were calculated for all items of standard goal system which had been presented in the first phase- paper of research works for rural resources evaluation. The results analysed and obtained in the study are summarized as follows; 1. In case that the number of resources items for evaluation are relatively large, stepwise matrix method is considered as the better one for pair-comparison works in view of evaluator's convenience and consistency. 2. The significance valuing results for most resources items showed a considerable difference between characteristic areas, especially in aspects of land and human resources, so being considered as wet reflecting the specific areal varieties, 3. On land resources, the items for industrial development and land use showed higher significance value, while natural environment resources the items for ecological varieties and on human resources the items for artificial facilities. However, lower-valued ones were the items for mineral stocks in land resources, for control and protection in natural environment resources and for lower-level culture heritage respectively.

A study to synthesize the recent concept and significance of quality and quality control has been performed in this paper. With understanding the recent market and manufacturing environment, we first discuss the significance of quality from the system view point. Then the existing definitions of quality have been rigourously examined and some significant features embeded in them have been derived. Through this examination, we specifically address "endless-effort for improvement" with three key elements required for successful implementation in quality control programs. Taguchi's quadratic loss function with regard to the addressed quality concept has also been discussed. Finally, we conclude this study with providing a view toward the development of new models.

This study was to identify the effect of the satisfaction of certification, the educational use of the company offering certificate, the system of confirmation of the same model and the demographic aspect on the companies to see if compulsory certification(KC certificate) has negative effects on company management. First, the satisfaction of certification could reflect positive influences on company management. Second, there is no statistical significance in the education from the company offering certificate as a result of analyzing relationships but education is required and has an effect on improving quality according to the result of frequency analysis. Last, the system to declare by identifying the same model has a difference in significance in sales account, the development of products and warranty service for products.

Checklist method is rapid and comprehensive to evaluate in practice. Check items are commonly rated by subjective utility function; i.e., evaluator's significant judgment. Since human judgment includes fuzziness (vagueness) inherently in spite of its significance, fuzzy set theory is useful in this case. The paper illustrates a evaluation method using fuzzy checklist where check items are rated as fuzzy numbers. Pairwise comparison data is used to determine the weights of check items, since it has comparative advantage for human's fuzzy judgment. Sample of BASIC program is provided for microcomputer. When uncertainty is due to subjectivity or imprecision of data, this method can be applied to practical problems widely.

The research interprets the principles of sampling error design for quality statistics models such as hypothesis test, interval estimation, control charts and acceptance sampling. Introducing the proper discussions of the design of significance level according to the use of hypothesis test, then it presents two methods to interpret significance by Neyman-Pearson and Fisher. Second point of the study proposes the design of confidence level for interval estimation by Bayesian confidence set, frequentist confidential set and fiducial interval. Third, the content also indicates the design of type I error and type II error considering both productivity and customer claim for control chart. Finally, the study reflects the design of producer's risk with operating charistictics curve, screening and switch rules for the purpose of purchasing and subcontraction.

The period of the Fourth Industrial Revolution is our near future and the ongoing changes in this age. We need to strive to adapt to this changes and also try to create new values. This study focuses on workers' perceptions and attitudes (self-efficacy, expectancy, and acceptance of change) toward the Fourth Industrial Revolution. These positive attitudes toward the upcoming future and the Fourth Industrial Revolution will influence on both the future and the current attitude, behavior and performance of employees. People have certain attitudes to the future, and these attitudes have an impact on current behavior. This paper tries to examine the positive attitudes toward the Fourth Industrial Revolution era and the influence of positive attitudes toward this new age on the current job satisfaction. Through this process, this paper explains what kinds of attitudes the workers should have in the Fourth Industrial Revolution era, and also sheds light on significance and purpose of this paper to explain how these specific attitudes toward the future influence the present performance such as job satisfaction.

Purpose The purpose of this study is to examine the effect that insecurity and autonomy of platform work have an influence on work-life balance and psychological well-being in an era of platform economy based on two characteristics of online platform work and self-determination theory. Design/methodology/approach This study suggested the structural equation model integrating two antecedents, insecurity and autonomy, work-life balance, and psychological well-being and proposed five hypotheses driven from the research model. A total of 334 valid samples were collected from platform workers by employing questionnaire including 24 question items of four constructs. Findings Three hypotheses were supported and one hypothesis was not supported at the significance level of 0.05. Insecurity of platform work has a negative influence on work-life balance at the significance level of 0.01, whereas insecurity of platform work has no a significant influence on psychological well-being. Autonomy of platform work has a positive influence on both work-life balance and psychological well-being at the significance level of 0.01. Work-life balance has a positive impact on psychological well-being at the significance level of 0.001. Insecurity have an influence on psychological well-being indirectly through mediation of work-life balance. Implications for academicians and practitioners were suggested.

In order to investigate the concentration of trace metals in human hairs from residents living in urban area and rural area, the 120 hair samples of adults were taken from urban areas(industrial area, bus terminal, downtown area) and rural area(Kasan-ri, Yeoju-up, Yeoju-goon) during July - September 1995. Mean concentrations of trace metals including lead and cadmium in human hair were compared by region, sex, presence of smoker, type of water, period of residence. The results were as follows; 1. The average concentrations of lead and cadmium in hairs of urban area are $0.92{\mu}g/g$ ($1.01{\mu}g/g$ industrial area, $1.01{\mu}g/g$ bus terminal, $0.74{\mu}g/g$ downtown area), $0.38{\mu}g/g$ ($0.54{\mu}g/g$ industrial area, $0.49{\mu}g/g$ bus terminal, $0.12{\mu}g/g$ downtown area). The mean concentrations of lead and cadmium in urban area are higher than the corresponding levels in the rural area. 2. Lead concentration for male in the urban and rural area is 0.94 and $0.62{\mu}g/g$, 0.90 and $0.60{\mu}g/g$ for female. But, It does not have any statistical significance. Cadmium concentration for male in the urban and rural area is 0.38 and $0.12{\mu}g/g$, 0.38 and $0.11{\mu}g/g$ for female. But It does not have any statistical significance. 3. Mean concentrations of lead and cadmium in smokers shows higher than non-smokers. It showed that the longer period of residence in urban area, the higher concentrations of three metals.
