The manufacturing system has been changed from labored manual process system, which is managed and operated by managers and operators, to CIMS(Computer Integrated Manufacturing System) for integration of manufacturing, research, development and consumption in the age of diverse customer's needs[6]. However, because it involves the hierarchical system composed of many sub-systems interface and its installation & setup cost is very expensive, CIMS has many difficulties in constructing the durable optimal system that is able to adapt to rapid in-outer circumstance change. So, HMS(Holonic Manufacturing System), the new conceptual manufacturing system having the self-problem-solving and self-organization[11], is instructed to solve these difficulties that it has in these days. The system flexibility in the HMS is able to be ensured, with the integration of human's strong points into mechatronics manufacturing system to reduce interference among sub-systems. In this paper, the manufacturing process rationalization and integration of the assembly line in an automobile industry, has lots of problems in efficiency and productivity, has been studied in an early stage of converting the present state of process system to HMS, which is human-oriented processing system, to improve the line efficiency, system productivity and reliability by using human capability effectively. This paper is derived into the human-oriented & object-oriented holons settlement of the shop floor system composed of processing, assembly and material handling system for the future holonic manufacturing system, which is going to be computer supported control system.

In order to solve the current problems and inefficiencies within the Port Authorities(PA) in Korea, this study introduces the concept of the integration of PA and analyses the intention of integration. This study is based on analysing the surveys participated by the members of PA. The surveys consist of six main factors which could influence the intention of integration of PA; contribution, autonomy, strategic factor, financial factor, marketing factor and environmental factor. The two main implications from this study can be categorised as follows. First, this study identifies the structural problems such as regional self-centredness of PA, obscurity of organisations' roles and their rights, limitations on diversification of business and restrictions within PA. Second, this study extensively discusses the option of improving the inefficiency whilst maintaining the current system or to switch to the integration of PA. In addition, it has been found that individual PA recognise the little need for integration. Since the results show that the strategic, financial, marketing and environmental factors would cause both significant and little significant impacts, it would be too haste to decide on a conclusion. However, it is possible to say that the rapid integration of PA can neither improve the efficiency nor improve the characteristics of each region. Therefore, the significance of integration of PA must be further discussed from many different perspectives. The results of this research will serve as a basic literature for further studies on the integration of PA in Korea. Moreover, the problems that have been identified and analysed in this study will contribute to establishing the strategy for further development of PA in Korea.

In general, a remotely operated vehicle(ROV) operates at deep sea. The control system of ROV is composed of two local loops; the first loop placed on the surface vessel monitors and manipulates the attitude of the ROV using joystick, and the second part on the ROV automatically controls thrusters and acquires positional data. This paper presents a position control simulation of a ROV using an adaptive controller and discusses the control effects of two different conditions. The design of an adaptive control system is obtained by the application of a self-tuning controller with the minimization of an appropriate cost function. The parameters of the control system are estimated by a recursive least square method(RLS). In the simulation, a Runge-Kutta method is used for the numerical integration and the generated outputs are obtained by adding measurement errors. Additionally, this paper discusses the mathematical modelling of a ROV and make a survey of control systems.

Previous studies on women who immigrated through marriage were focused on the frictional issues within the couples and their families as well as language tutoring. However, for the long-term integration of these women into society and the acquisition of status, it is most important to increase their economic value. Indeed many such women are facing economic difficulties, and have a strong desire to participate in economic activities. This study focuses on the economic self-sufficiency of these women through employment and entrepreneurship. We analyze their education level and employment experience and attempt to find the most effective policies to support them. We take particular interest in their entrepreneurial motivation and propose policies and frameworks for supporting their successful enterprise creation.

Purpose: This study was designed to identify the structural relationships among psychosocial variables related to sick role behavioral compliance among patients undergoing hemodialysis. Methods: The subjects were 476 patients from seven major hospitals and twelve dialysis centers located in D and P cities. Data were collected using self-report questionnaires. Data analysis was done by using SPSS/WIN 18.0 and AMOS 18.0 programs for structural equation modeling, to estimate the hypothesized model. Results: This findings support that a modified path model is efficient and appropriate to explain sick role behavioral compliance among hemodialysis patients. These factors account for 80.1% of the variance of sick-role behavioral compliance among hemodialysis patients. The variables having direct effect on sick role behavioral compliance were knowledge related to hemodialysis, social support, attitude, self-efficacy and intention. Conclusion: The modified model explains the integration process of psychosocial and behavior variables for sick-role behavioral compliance among patients undergoing hemodialysis.

The purpose of this study is to analyze the gender and self-development in love among single and married men and women. This study applies qualitative case study to make sense of the structure and the meanings of love experience associated with traditional gender role independence and interdependence,. This method focuses on the experiences and the meanings of love as understood by interviewees. Interview data used for this study were collected through in -depth interviews of 18 interviewees. The subjects were chosen from lower class and middle class men and women who lived in Soul. Major findings of this study were as follows; First it was found that there is the romantic ideologies of love and that women are responsible for their love relationships. This could be called " the feminization of love" Second feminized love was related to split gender role and caused to its costs for men and women especially conflict over intimacy. third even though there was still feminized love the trend to androgynouis love was found Androgynous love provided an alternative based on interdependence and the integration of love and self-development.velopment.

Objective : The current study investigated the effectiveness of group motor activity programs on motor function and perceived self-efficacy of children in the community children's center. Methods : Nine children aged six to nine years participated in this study. We applied the group motor activity program for 7 sessions. Before and after the intervention, children's motor function and self-efficacy were assessed using the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Short Form (BOT-2 SF) and the Perceived Efficacy and Goal Setting, Second Edition (PEGS-2), respectively. Results : The group motor activity program enhanced the motor function and self-efficacy of children. Conclusion : This study showed that the group motor activity program was effective for increasing the objective motor function and the subjective self-efficacy of children in the children's community centers. The result suggests that programs using activities in the community centers can facilitate children's self-development.

Objective : We investigated how sensory processing patterns contribute to temperament and character traits in undergraduate students. Methods : A total of 107 undergraduate students were recruited in September 2022 via convenient sampling method. They completed the Adolescent/Adult Sensory Profile and the Temperament and Character Inventory. Multiple regression models were applied to analyze the effect of sensory processing quadrants (low registration, sensation seeking, sensory sensitivity, sensation avoiding) on each temperament (novelty seeking, harm avoidance, reward dependence, persistence) and character (self-directedness, cooperativeness, self-transcendence) traits. Results : Sensation seeking significantly predicted high levels of novelty seeking, reward dependence, persistence, self-directedness, and self-transcendence but low harm avoidance. Low registration predicted high harm avoidance but low levels of reward dependence, persistence, and self-directedness. Reward dependence was predicted by high sensory sensitivity and low sensation avoiding. Conclusion : This study demonstrated that sensory processing patterns affected novelty seeking, harm avoidance, reward dependence, persistence, self-directedness, and self-transcendence in young adults.

Objective : This study was adapted into Korean for domestic use of the Sensory Processing and Self-Regulation Checklist (here in after referred to as SPSRC) and verified its content validity. Methods : The Korean version of the SPSRC, which was completed via a translation, content suitability, reverse translation, expert committee review, and content understanding process, was presented to three professors of the Department of Occupational Therapy and seven occupational therapists to confirm the content validity. Results : The content validity index (CVI) of the Korean version of the SPSRC was 0.9 or higher in all 130 items. Additionally, the CVI of all items was also 0.99, showing a high level of content validity result. Conclusion : The Korean version of the SPSRC was confirmed to have high content validity as a tool that can measure children's sensory processing ability and self-regulation ability together. The Korean version of the SPSRC facilitates the understanding and evaluation of children's sensory processing and self-regulation abilities in the clinical field, and is thought to be used to establish an intervention plan.
