The purpose of this study is to analyze the direct relationship between doctors and number of patients to be treated by applying many kinds of I E's techniques. Generally, doctors in this research work both at OPD & IPD. Under the hospital manegement system that they are applying in, doctor's daily working schedules are instable because the numbers of OPD patients very daily. Therefore, the amount of time they spend for inward Patients are variable too. So the numbers of Patients have great influence to the whole hospital system management. In the first place, the author researched and analyzed a QC of administrative system. Tn the second place, the author carried out Work Sampling with a view for understanding quantity of a doctor's operation. The author suppose this research and analysis is one approach for improving systematic lay-out planning at outpatient waiting room where has many problems to be solved and suggest several process for improvement.

The government supports the various systems on the premise of life-long education for improving the qualification of its people and supporting the lifelong career system. These systems help the educational activities for every generation from the teens. Each government department supports the learning activities for those who are related. In addition, each government department systemizes the regular education for advancing the performance of civil servant, by obliging a self-directed system to their member as well as by reflecting this educational activities in a promotion. This style of learning is provided not only offline but also online. However, not all necessary educational contents is furnished within the department. It is sometimes necessary to cooperate with the commissioned education and a professional educational institution. This thesis suggests three model systems while comparing one another. This paper suggests three system model. The first model is e-contents open place. The second model is e-contents open place. Finally, the suggest model is mixed form.

The purpose of this study was to examine the stressors of students in high school. Demographic data such as educational level of parents, mother's employment, family type, level of living, and students' growing place and their sex. The data were analyzed by t-test, one-way ANOVA, and Ducan Multiple Range Test. Students' stressors showed partial sex differences in each sub-category. Females feel more stress greater physical and mental health, sibiling relationship, whereas males feel more stress greater girl and boy friends. Students' stressors showed partially significant differences in only home environment and family stressors according to demographic variables. That is, home environment stressors differed in educational level of parents, mother's employment, family type, level of living, and students' growing place except mother's employment. Family stressors showed partially significant differnces in only family type and level of living.

More than a decade after their development and first wave of deployment, Six Sigma and Lean Manufacturing have recently returned on the corporate agendas of a larger number of corporations across industries and supply chains. In the wake of their re-surge, this commentary addresses the evolution, context, content and deployment patterns of the two distinct management concepts. It also analyses claims in the business press that a merger is taking place between Six Sigma and Lean Manufacturing. Here, it is found that there is not enough evidence to broadly support such claims, and it is only concluded that there is some evidence of an early tend towards a merger and that a possible merger would have many synergies and advantages. Finally, an example from a Scandinavian manufacturing company is provided that explains how Six Sigma and Lean Manufacturing can be used in a beneficial way for companies to reach world-class performance.

With the advent of the internet era, web-based virtual training system is gaining its importance in recent years. Because of the fact that the training can take place in any place and at any time, the virtual system is now replacing many of the conventional off-line classes. Hardware environments such as communication bandwidth and computer performance gets fast enough to accommodate the virtual education. Based on the observations on current virtual training system, this paper proposes three critical design rules required when developing a new virtual training system: i) With conceptual mapping, the menu hierarchy can be organized in a clear-cut manner, ii) Extensive use of multimedia tools can help students keep their attention to the lecture materials, and iii) Provision of interaction mechanisms helps students to gain their identity and motivation.

The chemical factory deals with dangerous element and more advance, human-error analyzes and becomes effective research for the country and region, this paper analyes the form of work-miss on human-error according to a safety accident for domestic chemical factory from 1999-2002. It include the present contents and raise issues human knowledge, behavior, judgment, sensibility as an important counterplan that makes the safety solution of work miss. For the point of view of human knowledge, it takes color standard for works to be effective in work place. for behavior, the test has been for risk point of work place and infra worker movement, also the workers performed professional work as classify according to work. for judgement, the valuation sheet is reflected to minimize the human -error and the 3rd supervisor does a cross-check audit beforehand. For sensibility, it is applicable for human relations, information, communication by program to the consciousness and an attitude of worker-supervisor.

Steel and iron manufacture works exist that many latency risk as melting liquid of high temperature, work of high place, and so on. Once in a while, the accident case make use of basic data for latency risk analysis in a place of business. In this paper, we investigated the cause of the accident in steel an iron works. The result, we came across that many latency risk in steel and iron manufacture works. The main type of risk are fall, narrow, come flying, etc. Most of the latency risk type are repetition and conventional accident. Accordingly, steel and manufacture works must prevent to repetition and conventional accident.

Mobile Node has to maintain communication as they move form place to place, so it doesn't guarantee Quality of Service(QoS). Fast Handoff is important to provide multimedia and real-time applications services in mobile, and it is closely related to handoff delay. Therefore, handoff delay problem is actively studied to quarantee QoS as a main issue in mobile IP research area. Next generation Mobile IPv6 resolve this problem somewhat, triangle problem for first packet and handoff delay still remain. In this paper, we suggest SNMP Information-based routing that adds keyword management method to Information-based routing in active network in order to resolve such a problem, and then suggest QoS controlled handoff based on SNMP Information-Based routing. After modeling of suggested method and existing handoff method, simulations are carried out with NS-2 for performance evaluation. The results of simulations show the some improvement on handoff delay, and therefore on QoS improvement.

The purpose of this study is to select suitable planting base for the mat-type rooftop greening in order to popularize rooftop greening system easily. The experiment was conducted from 2004 June to 2005 May under several conditions; 4 soil depths under mats(2cm, 5cm, 10cm, 15cm), two soil mixtures(natural soil 80%+leaf mold 20%, artificial soil) and two light conditions(full sun place, 20% shaded place). In this experiment, 3 types of mats were used ; the herbaceous plants mat(11 plants inclusive of Lotus corniculatus L., Silene armeria L.), the lawn mat with Festica arundinacea and Sedum mat with Sedum kamtschaticum, Sedum sarmentosum, Sedum oryzifolium, Sedum middendorffianum. The result is as follows; in the mat-type rooftop greening, the herbaceous plants mat, lawn mat and sedum mat are the similar number of plant and effect of greening on soil depth 2cm, 5cm and 10cm, 15cm. So suitable soil depth of rooftop greening is 10cm for the load and economical factor. Thus the mat-type rooftop greening possible planting base depth of all 13cm as soil depth 10cm and mat depth 3cm. As soil mixtures, the number and growth of plants were better mat and 'natural soil 80% +leaf mold 20%' than mat and artificial soil. In herbaceous plants mat, Silene armeria L., Dianthus chinensis, Centaurea cyanus L., Lotus corniculatus L. are survival in full sun place and Silene armeria L., Dianthus chinensis, Centaurea cyanus L. are survival in 20% shaded place. In conclusion, selection of suitable soil mixtures and plants is possible extensive management rooftop greening with effect of continuous greening. The mat-type rooftop greening are lightweight and simple preparation without management and can popularize readily.

This study examines the impact of residential environmental satisfaction on AIP(Aging in Place), and analyzes how their relationship differs depending on housing characteristic variables (ownership type, housing type, and residential area). For this purpose, as of November to December 2020, a questionnaire analysis was conducted on 373 adult males and females residing in Busan and Gyeongnam. The results of this study are summarized in two ways as follows. First, the higher the satisfaction with the residential environment, the higher the AIP. Second, it was analyzed that the positive relationship between satisfaction with the residential environment and AIP was higher in ownership than in rental cases, and further decreased in detached houses compared to apartment houses. In addition, compared to other regions, metropolitan cities or small and medium-sized cities had a higher positive (+) relationship between satisfaction with the residential environment and AIP. This study will provide important implications for policymaking related to population and urban planning.
