Incidence matrix is a useful tool for presenting incomplete block designs; however, it is inadequate to use only an incidence matrix in examining whether a certain incomplete block design becomes a balanced incomplete block design or not. We can use a structural matrix as a useful tool to show whether a certain incomplete block design becomes a balanced incomplete block design or not. We propose an augmented incidence matrix and ${\lambda}$ matrix as another tools for evaluating incomplete block designs. Through the augmented incidenc matrix and ${\lambda}$ matrix, we can ascertain whether a certain incomplete block design becomes a balance incomplete block design or not.

Recently, as the demand for high efficiency, multi-function machine tools has increased, domestic machine tool industries are investing in research and development for Gantry-Type Machining centers. In this thesis, for the purpose of evaluating machining accuracy and designing a machine tool structure, a simplified model of the main frame is suggested. The results show the general characteristics of the optimum design, and the approach is shown as practicable for the preliminary design analysis and improvement of a conceptual design of a Gantry-Type Machining center. This paper's results are expected to improve the static characteristics of Gantry-Type Machine centers. The three-dimensional finite element models proved that the modeling method might be applied to real machine tool structures.

A standardized ergonomics kit is suggested to evaluate and reduce musculoskeletal hazards that yield large socioeconomic burdens in the work system. This kit comprises basic and detailed analysis tools with proper tool selection rules. The basic tool includes a checklist for various risk factors to screen potentially hazardous jobs among manual works. Selective detailed analysis tools can then be applied to the screened job lists for more quantitative and precise evaluation. The tool selection rules are devised for using the basic and detailed analysis tools in a mutually supplemental way. To validate the standardized ergonomics kit, it was applied to evaluate jobs related to the musculoskeletal hazards in a paper-making industry. Among 101 manual jobs investigated, 44 potential hazardous jobs were screened during basic investigation phase and finally 16 hazardous jobs were identified by the detailed analysis phase. The result provided fairly promising ideas of ergonomic interventions for the hazardous jobs.

Any relative deformation between the cutting tool and the workpiece at the machining point, results directly in form and dimensional errors. The source of relative deformations between the cutting tool and the workpiece at the contact point may be due to thermal, weight, and cutting forces. This paper presents an investigation into dry and fluid machining with the objective of evaluating shape accuracy effect for the turning process of Al6061. The thermal distribution of cutting tool and cutting force was predicted using finite element method after measuring the temperature of the tool holder. To reach this goal, shape accuracy turning experiments are carried out according to cutting conditions with dry and fluid machining methods. The variable cutting conditions are cutting speed, depth of cutting and feed rate.

Purpose: 'Yangsaeng' is a traditional health care regimen for the promotion of health and prevention of illnesses ty means of specific principles and methods for the purpose of living a long and healthy life. The purpose of this paper was to develop a tool in measuring Yangsaeng and to verify its reliability and validity. Method: Content validity was conducted three times by 8 experts. Factor analysis was conducted to test its construct validity. Result: Thirty-one items were selected in 8 factors; Morality Yangsaeng, Mind Yangsaeng, Diet Yangsaeng, Activity & rest Yangsaeng, Exercise Yangsaeng, Seasonal Yangsaeng, Sleep Yangsaeng and Sex life Yangsaeng. The explanatory variance is 61.76%. Cronbach's alpha of the final tool is .89 and that of each factor is .68～.82. The analysis of the items shows that the item-total correlation is .40 or higher. Criterion-related validity was verified with the CMCHS V1.0 and the KoHSME V1.0. Conclusion: Since the tool developed in this study was verified in terms of its reliability and validity, it could be utilized as a tool for evaluating the extent of Yangsaeng.

Objectives; The purpose of this study was to develop a framework for home care and a Home Care Need Assessment Tool. Method 1. Identifying common domains in the provision of home care. 2. Charts of 253 home care clients were reviewed to obtain a classification of the nursing diagnoses. 3. A focus group methodology was used to develop the domains. 4. The tool was applied to 439 home care clients.(Kappa value=0.460-1.000, sensitivity, 0.444-1.000: specificity, 0.743-1.000). 5. Some refinements and extractions of the defining characteristics and related factors were made based on the results of the focus group. Results Home Care Need Assessment Tool consists of three parts; -Part I : factors related to basic conditions -Part II : a screening component that enables home care nurses to assess 30 multiple domains of 53 nursing diagnoses. -Part III : summative nursing diagnoses and nursing need intensity for the clients. Conclusion This tool provides a comprehensive assessment that helps the recognition of many strengths as well as problems of the clients. It will be usefully utilized in scheduling home care nursing plans and evaluating client outcomes.

Purpose: The purpose of this study was to development and measure validity and reliability of evaluation tool for clinical nursing practice competency of Nursing students. Method: The participants in this study were 568 nurses who had worked for more than three years above in hospitals. A questionnaire of 79 items was administered to the nurses using a convenience sampling method. The data were collected from Sep. 12th, to Oct. 20th, 2004. Result: The derived outcome tool consisted of 6 factors of direct nursing actions and 6 factors of indirect nursing actions on the basis of 79 items. The 6 factors in direct nursing actions accounted for 76.84% of the variance and 6 factors in indirect nursing actions accounted for 79.68% of the variance on total scale. As a result of the item analysis, 79 items were selected and the internal consistency alpha coefficient was .9917. The value of Cronbach' alpha of direct nursing actions was .9640, indirect nursing actions was .9550.

Purpose: This study was done to develop performance appraisal guidelines based on the standardized appraisal tool developed in a previous study. Methods: A preliminary investigation was done to draw up a draft guidelines through a literature review. To verify the content validity of the guidelines, 10 nurse managers reviewed the standardized appraisal tool and draft guidelines. Through this process, the performance appraisal guidelines were revised and supplemented. In order to examine the reliability and validity of the guidelines, 13 nurse managers conducted performance appraisal for 178 nurses. Results: As a result, the items of pre-existing tool was reduced from 63 to 30 for usefulness, and guidelines for each items were developed. Conclusion: The revised performance appraisal tool and guidelines are expected to be useful in objectively evaluating nursing performance objectively.

One of the failure mechanism of spaceborne electronics is a fatigue fracture on solder joint under launch random vibration. Thus, a necessity of early diagnosis through the fatigue life evaluation on solder joint arises to prevent such potential risk of failure. The conventional life prediction methods cannot assure the accuracy of life estimation results if the packaging type changes, and also requires much time and effort to construct the analysis model of highly integrated PCB with various packaging types. In this study, we performed life prediction of PCB based on a reliability and life prediction tool of sherlock as a new approach for evaluating the structural reliability on solder joint, and those prediction results were validated by fatigue tests. In addition, we also investigated an influence of solder height on the fatigue life of solder joint. These results indicated that the Sherlock is applicable tool for evaluating the structural reliability of spaceborne electronic.
