Up-to-date market dynamics and intense competition have forced a production system to be more widely distributed and decentralized than ever, and the production system itself can be regarded as a collaborative network of autonomous production resources in which the responsibility of decision making is also decentralized into individual autonomous entities. The conventional resource management models, however, are not suitable for the distributed and decentralized environment because of their centralized nature. In this paper, an agent-based resource management model is proposed. The proposed model applies employment relation-driven fractal organization (FrOrg) into organizational model for distributed production resources and presents a resource management framework based on employment contracts. The fractal organization is a structured association in which a self-similar pattern recursively appears, and employment relations between production resources are recursively constructed throughout the entire production system.

This paper adopts an embeddedness perspective and discusses rationales for government intervention in relation to economic development. Looking at East Asian experiences with industrial and technology policy the paper examines the general requirements, specific areas of focus and appropriate techniques for industrial and technology policy. Eight generic policy requirements are identified, viz. government capacity; monitoring and adjustment; policy sequencing; incremental upgrading; progressive market reliance; performance-orientation; selectivity; and flexibility.

This study was designed to determine anxiety factors and levels of anxiety of foreign industrial workers. One hundred and seventy five workers were researched who were working in Guro Working Complex, Ansan City and Sungnam City Working Complex asking 60 questionnaires from Feb. 25, 1996 to April 12, 1996. The results were as follows ; 1. The 30.3% of foreign workers were from Nepal, 17.7% from Bangladesh, 10.9% from SriLanka, 14. 9% from Philippines, 1.1% from Ghana. 80% of foreign workers were male, 11.1% were single and most of them were in the age from 25 to 34. 37.1% of foreign workers had not lived in Korea less than 12 months, 58.8% graduated from college, 33.7% from high school, and more than half lived in a dormitory. 2. On the anxiety level related to subject workers' general characteristics, the anxiety level from Nepal recorded the highest point 2.70 statistically showing a significant difference(p=0.0003). On the physical anxiety level, the workers from Nepal recorded a significantly low point comparing with Jamaica, Burma, Vietnam and Nigeria(p=0.01). 3. Emotional anxiety level marked the highest on the workers living as a tenant comparing with the workers in dormitory. 4. On anxiety factors, the emotional anxiety recoded the highest, the social anxiety and the somatic anxiety. 5. On the relation between the anxiety factor, the somatic anxiety factor had a relation with emotional, environmental, and occupational factors and on the other relation between the anxiety factor and emotional factor had a relation with environmental, social, cultural factors. Moreover, the environmental factor had a relation with the cultural factor, social factor had a relation with the cultural factor, and cultural factor was related to the occupational factor.

Purpose: This study was to figure out relationships of perceived Technology Readiness Index(TRI), usefulness, acceptance intension, and the recognition of substitute employment of medical personnel on the artificial intelligence (AI) and internet of things (IoT) among main technologies. Methodology: To achieve the purpose, this study utilized structured survey tools to conduct a questionnaire survey of nursing, administrative and medical technology professionals at six university hospitals in Korea metropolitan area. A PLS(Partial Least Square) Path analysis was utilized To analyze the material. Findings: In the relation with the technology readiness and perceived usefulness, it had a positive influence to the perceived usefulness when the optimism and innovativeness were higher and the discomfort was lower. In the relation with the technology readiness and acceptance intension, it showed a positive influence when the innovativeness was higher and the discomfort was lower. In the relation with the perceived usefulness and acceptance intension, it had a positive influence to the acceptance intension when the perceived usefulness was higher. In the relation with the acceptance intension and the recognition of substitute employment, it showed a positive influence to the recognition of substitute employment when the acceptance intension was higher. Practical Implications: Judging based on the above study results and reference reviews, it confirmed that it is necessary to prepare in the level of hospital organization in the $4^{th}$ Industrial Revolution. They should increase the efficiency of human resources through the technological factors or changes of employment types for the additional demands of human resources to handle increasing medical demands or induce to secure necessary abilities which are changing at the right time by performing the $4^{th}$ Industrial Revolution related re-training continuously to develop the value of existing human resources.

This paper studies the two supplier inventory system in which order-level inventory policy with constant leadtimes is adopted. An optimal ordering policy to achieve the expected minimum total inventory cost is found by utilizing the concepts of the equivalence relation. Sensitivity analysis of the system parameters, the replenishment cost and the unit price, is done through a numerical example.

Quality Control Circle activity is widely introcuced by manufacturing industries. Q.C.C. is studied not only in relation with five points of view such as corporate culture, labor union, organizational management model in Korea, the Theory W and educational revolution etc. but also in social, cultural background, and national trait's view points. The main goal of this study is to investigate sucessful role and active application in Quality Control Circle activity.

Because sampling interval for data collection tends to be short compared with the overall processing time, in chemical process, instrumental process related tanks or furnace collected data have a significant autocorrelation. Insufficient control technique and frequent control actions cause unstable condition of the process. Traditional control charts which were developed based on iid (independently and identically distributed) among data cannot be applied on the existence of autocorrelation. Also unstable process is difficult to identity or diagnose. Because large-scale process has a lot of measurable variables and multi-step-structures among data, it is difficult to find relation between measurable variables and nonconformity. In this paper, we suggested an appicable model to diagnose the process and to find relation between measurable variables (CTQ) and nonconformity in the process having autocorrelation, unstable condition frequently, a lot of measurable variables, and multi-step-structure. And we applied this model to real process, to verify that the process engineers could easily and effectively diagnose the process and control the nonconformity.
