Pearson's correlation was used to determine relations between infiltration and affecting factors using flow monitoring data measured in 24 areas with different characteristics. Factors showed relatively high correlations than others were indexed to determine infiltration rates of the study area. Among 8 factors(service area, sewer length, sewer diameter, multiplier of sewer length and diameter, number of manholes, population, number of properties, number of households) tested, the multiplier of sewer length and diameter, the number of population and the number of household in each service area indicated higher correlation coefficient(>0.8) than others. The goodness of fitness of linear regressions between infiltration and the factors followed the order: sewer length and diameter(0.68)> population(0.65)> number of household(0.60). Infiltration rates calculated by the multiplier of sewer length and diameter, the number of population and the number of household in each service area were 0.046~1.0396 $m^{3}/d{\cdot}mm-km$, 0.0917~1.7355 $m^{3}/capita{\cdot}d$, 0.196~4.529 $m^{3}/household {\cdot}d$ respectively. After sewerage rehabilitation work of the area, the infiltration rates calculated by above factors with high correlations are expected to be used for comparing effectiveness of the work once they are estimated under the same flow measuring conditions.

This research aims to examine the experiences of hospital dietitians' burnout and the factors of their burnout, such as demographic factors, unique characteristics of hospitals, their self-respect, and organizational factors. In order for this, a questionnaire survey was conducted with hospital dietitians working in general hospitals of over 400 beds in the Seoul Metropolitan area. The average point of self-respect of dietitians is 3.67 out of 5.00. Their experience of burnout turned out to be 3.17 out of 7, the extent of job satisfaction is high, that is 3.35 out of 5.00. The decrease of personal accomplishment is shown to be closely related to the burnout of dietitians. The emotional exhaustion in burnout at the significant level 0.001 is increasing as the annual gross salary is low, their age is young, extra-working hours are long, and is high to the dietitians serving meals and working at entrusted companies. The factors affected by burnout experience vary with individual circumstances. So, to prevent the emotional exhaustion, depersonalization, and reduced personal accomplishment, hospital dietitians' spiritual and physical health needs to be kept up by their self-development and investment.

The job design was frequently tried in many enterprises in order to give workers the job satisfaction, but there remains obscure about what kinds of human factors in job yield the satisfaction. This study is concerned with an experimental method for job design to account for such findings that work with conveyor gave workers unsatisfaction, and that enlarged job of work resulted in high job satisfaction.

Purpose: This study was to identify factors that influence the health care needs of that over 65 years of age in Mokpo, Korea. Method: The data was collected from June 2002 to September 2002. The subjects were 120 homebound solitude elderly(age=76.8). Subjects were interviewed with structured questionnaire in order to identify the health care needs, health variables (perceived health status, risk of malnutrition, K-IADL), psychological variables(self-esteem, depression) and demographic variables. physiological health variables (height, weight, blood pressure, pulse, blood sugar)were assessed after the interview. Result: In general perceived health status was poor, risk of malnutrition was high, number of disease was 3 disease, self-esteem was low but depression was high and health care needs were relatively high. Among the elderly education & counseling needs topped the list. In regression analysis, health care needs were significantly influenced by IADL(23%), duration of solitudes(4%), sex(3%), and education(l%). These variables explained 31% of the variances in health care needs. Conclusion: The result identified that health care needs should be a considered in IADL, female, duration of solitudes and education for the solitude elderly.

The most dominate aspect in machine works using CNC devices in industrial production processes is the precision of the product and the Cycle Time. To this day, many studies on the external factors of the technology to reduce the Cycle Time have advanced amid to the advancements in cam soft development for manual programs and the numerous studies on high speed and precision machining. This study experimented various functions of the sequence pattern flow and arranged system development technologies of past few years to develop and applicate various usage of adjustment factors within the CNC, so it would be more understandable to the user and would enable them to make high speed and precision products more faster develop and. In order to reduce the Cycle Time, the mechanism of machine tools has to be analysed and applied, in addition to program reduction and improvement of the manufacture process.

The effective construction for ready-made clothes is one of the central concerns of both consumers and manufactures in today's apparel industry. So in order to reduce the burden of stocks and increase clothing fitness, systematic information on typical body size and somatotypes is essential. This study was performed to provide fundamental data on junior high school girls' somatotype by classifying the lower body somatotype and analyzing the characteristics of each somatotype. The subject were 234 Korean Junior High School Girls. The subjects were directly measured anthropometrically and indirectly analyzed photographically. The result of factor analysis indicated that 6 factors were extracted through factor analysis and those factors comprise 70.2% of total variance. Using factor scores cluster analysis was carried out and the subject were classified into 3 cluster as their lower boby front and side silhouette.

This study was performed to provide fundamental data on junior-high school girls' somatotype by classifying the lower body somatotype and analyzing the characteristics of each somatotype. The subject were 236 Korean junior-high school girls. The subject were directly measured anthropometrically and indirectly analyzed photographically. By direct measurement, 5 factors were extracted through factor analysis and the subject were classified into 4 duster as their lower body front silhouette. By indirect measurement, 5 factors ore extracted through factor analysis and the subject were classified into 3 cluster as their lower body side silhouette. After combining the body types of the front and the side silhouette, we selected 4 basic body types out of combination.

Non-traumatic acute abdominal pain in children presents a diagnostic dilemma. Numerous disorders can cause abdominal pain. Although many etiologies are benign, some require a rapid diagnosis and treatment in order to minimize morbidity. This review concentrates on the clinical office evaluation of acute abdominal pain in infants and children and details the clinical guideline for the diagnostic approach to imaging and the salient clinical features of some of the conditions. The clinical outcomes of children presenting with acute abdominal pain and the risk factors of the high risk underlying diseases would be provided for the diagnostic algorithm.

Running test of the Korean High-Speed Train using remote controlled measuring system have been executed on the high speed track in order to evaluate and verify the performance of the train. In this paper, influencing factors on the contact force which represents dynamic characteristics between the pantograph and contact wire are analyzed, according to the track condition, span type and running condition. By the analytical study on the test data, we figured out that contact force and dynamic characteristics of the pantograph are mainly affected by running behavior of the train and the span distance which the train passes.

Generally, photoelastic experimental data were measured in the closed vicinity of crack tip to determine stress intensity factors of a crack with photoelastic experiment method. In this case, only the first order term has been considered in the equation of stress field. But because it is very difficult to measure the correct photoelastic data in the closed vicinity of crack, the accuracy of experimental results was very poor. By including the high order terms in the stress field equation we could obtain the accurate S.I.F values by using clear photoelastic data in the distant region from crack tip instead of unclear photoelastic data in the vicinity of crack tip.
