Whereas in non-symmetrical distribution manufacturing process they are not plotted relatively on the centeral line but plotted on the skew of right-hand side or left-hand side. That is to say, for the prupose of producing either upper-specification-oriented items or lower-specification-oriented items, and when we carry out tighter control so as to have them pass only its specifications, the distribution shape naturally has a non-normal distribution. In these cases, we could use either compressed control limits or variable transformed logarithm control charts. It the above mentioned methods were not available, we should use special purpose control chart-Mode control chart or Gram-Charlier control chart. These are proper methods for manufacturing process control which uses control chart method. In spite of these methods, domestic manufacturing and mining companies are utterly ignorant about these methods. That invites practical problems in their companies. To enhance this improvements, I proved the property of practical applications of control chart method by comparing and analyzing the case studies of practical application of speical purpose control chart method, and also by introducing the application methods.

Purpose: The purpose of this study is to propose adoption of QFD and Stage-gate in order to analyze the quality of korea defense system. Methods: Drawing change data of initial production phase in korea defense system were anlayzed and a practical method was proposed. Results: The results of this study are as follows; Off line Quality Control should be introduced in development phase. Specially, in case of defense system, the best method is QFD(Quality Function Deployment) and Stage-gate process. At first, QFD 1 step defines product planning from VOC(Voice Of Customer), QFD 2 step specifies part planning from product planning, QFD 3 step defines process planning from part planning, QFD 4 step defines production planning from previous process planning. Secondly, Stage-gate process is adopted. This study is proposed 5 stage-gate in case of korea defense development. Gate 1 is located after SFR(System Function Review), Gate 2 is located after PDR(Preliminary Design Review), Gate 3 is located after CDR(Critical Design Review), Gate 4 is located after TRR(Test Readiness Review) and Gate 5 is located before specification documentation submission. Conclusion: Off line QC(Quality Control) in development phase is necessary prior to on line QC(Quality Control) in p roduction phase. For the purpose of off line quality control, QFD(Quality Function Deployment) and Stage-gate process can be adopted.

PURPOSE: PURPOSE: The purpose of this study was to analyze the effect and examine the feasibility of an intervention of ankle strategy exercise on balance of patients with hemiplegia. METHODS: The subject were randomly allocated to three groups: ankle strategy exercise (group A), balance exercise (group B) and control (group C). Group A was received the conventional physical therapy plus ankle strategy exercises for 20 minutes in one session. Group B was received the same conventional physical therapy plus balance exercises for 20 minutes in one session. Two active groups were performed in the session 3 times a week, for a total of 6 weeks. and Group C was only received the same conventional physical therapy. Balance test was assessed using center of pressure (COP) in the anteroposterior (A-P), mediolateral (M-L) direction, Berg balance scale (BBS) and Timed Up and Go Test (TUG). RESULTS: All groups showed improvements in balance parameters. In especial, the Group A was statistically significant differences in almost part evaluation items and showed more improvements in BBS and TUG parameters than Group B and Group C. and moving distance of M-L COP was more improvements than Group B. CONCLUSION: Ankle strategy exercises had more influence on balance than balance exercises and neurodevelopmental treatment.

The purpose of this study is to develop dynamic-stochastic models that can forecast the inflow into reservoir during low/drought periods and flood periods. For the formulation of the models, the discrete transfer function is utilized to construct the deterministic characteristics, and the ARIMA model is utilized to construct the stochastic characteristics of residuals. The stochastic variations and structures of time series on hydrological data are examined by employing the auto/cross covariance function and auto/cross correlation function. Also, general modeling processes and forecasting method are used the model building methods of Box and Jenkins. For the verifications and applications of the developed models, the Chungju multi-purpose reservoir which is located in the South Han river systems is selected. Input data required are the current and past reservoir inflow and Yungchun water levels. In order to transform the water level at Yungchon into streamflows, the water level-streamflows rating curves at low/drought periods and flood periods are estimated. The models are calibrated with the flood periods of 1988 and 1989 and hourly data for 1990 flood are analyzed. Also, for the low/drought periods, daily data of 1988 and 1989 are calibrated, and daily data for 1989 are analyzed.

The nature of work which is changing has increased the importance of HRD within organization. Also, these changes are making HRD shift its paradigm : from the segregated, closed, operational & administrative, dependent, utilitarian view to the integrative, open, strategic & facilitative, interdependent, generative view. The shifts of the perspective on HRD cause HRD professionals rethink the purpose and definition of HRD, and the role & competency needed to HRD in 21st century. The findings which are drawn through literature review and researcher’s intuition based on a long field experience are as follows. First, The function of HRD has recently been much more important then that of the past. Second, There is no consensus over the conceptual identity of HRD. Nonetheless, it is apparent that the preferred activities of the HRD function is performance improvement. Third, It is too difficult that we should define clearly the role & competency of HRD because of diverse perspectives on them. But we find much evidence converging to support the fact that the role & competency of HRD should be extended from the sole focus on training & development to adding the additional role & competency of change agent, who includes planning, implementing, and managing change.

Purpose: The purpose of this study is to explore and understanding the nature of the shift workers' experience in industries requiring 24 hours-a-day service provision and support. For the Purpose, the present researcher made a research Question, "What are workers' experience in the shift work?" Methods: In the study, 5 male shift workers, 3 female shift worker and a woman (key informant) whose husband is a shift worker participated. Then profound interviews with the participants were made after their agreement. Results: The researcher classified the significant statements under 6 theme clusters, 1) sense of difference; 2) worries about health; 3) draining of emotion; 4) anxiety; 5) sadness; and 6) being comfortable. Conclusions: Shift work which is inevitable in modern society may have severe influences on shift workers' physical, mental and psychological aspects by causing their work cycle rhythm to be unbalanced. Finally, the researcher hopes that the results of the study would help understand workers' life and increase social concern and support to the workers.

Purpose: The aim of this study is to identify the expectations and perceptions of health center users as to the services. SERVQUAL scale was used for measurement of service quality. The purpose of this study is to offer baseline data for improving the quality of health care services. Methods: The subjects were users of a health center in S City in Kangwon-do; 170 people participated in this study. Results: Regarding service quality depending on general characteristics, the following results were obtained. First, there were statistically significant differences depending on the gender, purpose of visit, and satisfaction in the health center. Second, the services fell short of the expectations. Third, the quality of 'safe, accurate services' scored the highest, while 'empathy and friendliness' scored the lowest. Fourth, 'internal, external environment of the health center' scored the highest, while 'courtesy of staff' scored the lowest. There were no statistically significant differences. Conclusion: Based on the findings, the following are suggested. First, employee education should be provided for development of empathy and interaction with patients; those are the weakest areas in the health care services. Second, a system allowing patients to understand and participate in their treatment should be developed.
