A new last design approach based on the Limb line FFD (LFFD) and Scale factor FFD (SFFD) is presented in this paper. The proposed last design method utilizes the dynamic trimmed parametric patches for the measured foot 3D data and last 3D data. Furthermore, the proposed last data generation system utilizes cross sectional data extracted obtained from the measured 3D foot data. First, the last design rule of the LFFD is constructed on the FFD lattice based on foot last shape analysis. Secondly, SFFD is constructed on the LFFD new lattice based on scale factor deformation. The scale factor is constructed on the boundary edges of polygonized patch and the cross section last data boundary edge of the polygon object. Suppose the two boundary curves have been preprocessed so that they run in the same direction and they forms the SF(Scale Factor). In addition, the control points of FFD lattice are derived with cross. sectional data interpolation methods from a finite set of 3D foot data.

The correlations among the fourteen items of the Bortner Scale are proved not to be very strong. In this case the method of flat summing of all the variables(Johnston and Schaper 1983) can be little valid because each variable has a statistically different weight. The Bortner Scale through the factor analysis of the German data has shown a diverse factor structure of Type A behavior that contains five sub-factors such as ‘speed and urgency’, ‘introversion’, ‘little listening to others’, ‘competitiveness and ambition’ and ‘mobilization’. And what is more, the Bortner Revised Scale through another factor analysis of the Korean data has revealed more complicated factor structure which is composed of eighteen sub-factors. In addition, only two of the German five sub-factors such as ‘speed and urgency’ and ‘mobilization’ are associated with cardiovascular disease. The association is stronger in infarction than in angina pectoris.

In this paper, we describe the analysis and the compensation method of the g-sensitivity error for MEMS vibratory gyroscopes. Usually, the g-sensitivity error has been ignored in the commercial MEMS gyroscope, but it deserves our attention to apply for the missile application as a tactical grade performance. Thus, it is necessary to compensate for the g-sensitivity error to reach a tactical grade performance. Generally, the g-sensitivity error seems intuitively to be a gyroscope bias error proportional to the linear acceleration. However, we assert that the g-sensitivity error mainly causes not a bias error but a scale-factor error. And we verify that the g-sensitivity scale-factor error occurs due to the non-linearity of parallel plate electrodes. Therefore, we propose the compensation method to remove the g-sensitivity scale-factor error. The experimental result showed that a proposed compensation method improved successfully the performance of the MEMS vibratory gyroscope.

The purpose of this study is to investigate how the marital conflict and the conflict-coping method of self and spouse have an effect on the marital satisfaction in the early stage of marital life. The subjects of this study are the 132 couples in the area of Taegu and Pohang city. The instruments of measurement are marital conflict scale, conflict-coping method scale and Kansas marital satisfaction scale(KMSS). The data are analysed through factor analysis, Cronbach's ${\alpha}$, frequency, percentile, mean, standard deviation, paired t-test and stepwise regression analysis. The major findings of this study are as follows: Firstly, as a result of figuring out couples' marital conflict, husbands and wives are having the highest conflict in the personality factor. The difference of marital conflict between husbands and wives is shown significant in the relative factor. Secondly, as a result of figuring out couples' conflict-coping method, husbands and wives use mostly the reasonable behavior and leastly physical aggression. The difference of conflict-coping method between husbands and wives is shown significant in the verbal aggression, adjustment renunciation and physical aggression. Thirdly, as a result of figuring out how the marital conflict and the conflict-coping method of self and spouse have an effect on the marital satisfaction, the communication factor of the conflict factors, the wives' verbal aggression perceived by husbands, and the reasonable behavior of the self have much effect on the marital satisfaction in case of husbands. And the personality factor, sexual factor and role factor of the conflict factors and the husbands' verbal aggression and reasonable behavior perceived by wives have much effect on the marital satisfaction in case of wives.

The purpose of this study was to develop an instrument for assessing Korean mother's child rearing attitudes. The study attempted to explore dimensionality of maternal attitudes and formulated conceptual framwork. The items of maternal behaviour scale were tested on 300 mothers of 4th∼6th grade elementary school children living in urban areas. By the method of reliability analysis and factor analysis, 43 items were finally selected for the scale. The reliability of the new scale was ranged from .57 to .80. The construct validity of the scale was supported by the results of factor analysis.

Purpose: The purpose of this study was to develop the Nurse Presence Scale and to test the reliability and validity of the instrument. Method: The subjects verifying the scale's reliability and validity were adult patients being treated in three artificial kidney unit in Pusan and Taegu from August 1 to October 15, 2000. The data was analyzed by the SPSS/WIN 8.0 program. Result: A factor analysis and was conducted items that had a factor loading more than .40, and an eigen value more than 1.0 were seleclted. The factor analysis classified a total of seven factors statistically, but the seventh factor was excluded because community was less than 4%. Therefore, there were six factors, and its communality was 62%. The explanation of domain and factors based on the conceptual framework and item content are as follows: The first factor was 'interaction' in emotional areas, the second domain was 'empathy' in cognitive areas, the third was 'attention' in emotional areas, the fourth was 'openness' in emotional areas, the fifth was 'sensitivity' in behavioral areas, and the sixth was 'physical assist' in behavioral areas. Cronbach's α coefficient to test reliability of the scale was .9766 for a total 49 items. Conclusion: The Scale for Nurse Presence developed in the study was identified as a tool with a high degree of reliability and validity. Therefore, this scale can be effectively utilized for the evaluation of nurse presence in clinical settings.

Purpose: The purpose of this study is a preliminary study to develop a comprehensive information avoidance scale that includes various search contexts. Research design, data and methodology: This study is a part of exploratory sequential design of mixed method for the development of information avoidance scale. Based on the themes derived from the analysis of the in-depth interview data collected in the qualitative research of the first stage of the study, 45 preliminary items on information search and avoidance were constructed. The factors related to information searching included information recognition, information seeking purpose, and information search expectations. Individual, information, time, and system factors were related to information avoidance. Pearson's correlation analysis was performed for the correlation between factor items, and Cronbach's alpha analysis was performed for the reliability analysis of the items. Exploratory factor analysis was applied to examine the construct validity of 35 items of information avoidance. Results: Among the information avoidance items, one of the less relevant among information purpose items, two information factor items, and one time factor item were excluded. Conclusions: A secondary survey should be conducted to confirm the validity and reliability of the scale composed of adjusted items (35) based on the results of exploratory factor analysis. The strength of this preliminary scale is that it was developed based on vivid qualitative data of ordinary people who had experiences of search and avoidance in various search contexts.

We discovered the fact that the most important factor for judging adults' internet addiction in the K-scale method which was developed by Korea National Information Society Agency (NIA), has composed of 4 categories including 20 items, is tolerance and preoccupation factor from the experiments by using data mining techniques. In this research, we propose a new internet addiction diagnostic method based on the degree of tolerance considering users' non-duty internet activities. From some questionnaire participants, their feedbacks for the K-scale and the proposed diagnostic method were collected, and then we confirmed that the proposed user-centered diagnostic method is effective to find undiscovered addicts due to individuals's intention in the K-scale.

This study has been designed to develop a health behavior scale. Data were collected through a survey over a period of two month period. Subjects who participated in the study were 298 Korean adults. The author used a convenience sampling method. The analysis of the data was done with SPSS PC for descriptive statistics and factor analysis. Initially 34 items were generated from the interview data of twenty one adults and from literature review and survey. This preliminary scale was analyzed for a reliability and validity. The results are as follow : 1. Crombach Coefficient alpha for the 30 items was .7907. 2. Factor analysis was done in order to confirm construct validity and nine factor were extracted from the results. These contributed 54.4% of the variance in the total score. 3. Nine factor label were 'exercise' 'stress management' 'energy conservation' 'limit in liking' 'selection of food' 'ingestion of natural food' 'health examination' 'relaxation' and 'nutrition'. The author suggests that this scale could be adequately applied in assessing the health behavior of Korean adults. The results of using this scale in a study can contribute to designing an appropriate health promotion strategy.

In the present research, differential quadrature (DQ) method has been utilized for investigating free vibrations of porous functionally graded (FG) micro/nano beams in thermal environments. The exact location of neutral axis in FG material has been assumed where the material properties are described via porosity-dependent power-law functions. A scale factor related to couple stresses has been employed for describing size effect. The formulation of scale-dependent beam has been presented based upon a refined beam theory needless of shear correction factors. The governing equations and the associated boundary conditions have been established via Hamilton's rule and then they are solved implementing DQ method. Several graphs are provided which emphasis on the role of porosity dispersion type, porosity volume, temperature variation, scale factor and FG material index on free vibrational behavior of small scale beams.
