This study has two research objectives related to end-user computing (EUC). One of the research objectives was to investigate the current status of EUC of Korean firms. Another research objective was to examine the relationship between individual differences of end-users and EUC success. Using survey data from 752 end-users of 23 firms, the current status of EUC and the relationship between individual differences of end-users and EUC success were investigated. The current status of EUC was examined from six perspectives : 1) what is the characteristics of EUC strategy of Korean firms, 2) what are the individual characteristics of end-users in Korean firms 3) what are the characteristics of tasks performed by end-users computer, 4) what are the application areas of EUC, 5) How end-users are satisfied with the support of firm, 6) what are system usage and satisfaction of end-users. It was also found that individual differences of end-users are related to EUC success. More specifically, it was shown that the male gender, younger age, higher level of education, higher rank and organizational tenure, higher math ability, thinking type of cognitive style, positive and optimistic attitudes toward computer, more experience with computer, more computer education and knowledge are individual differences variables associated with EUC success. The results of stepwise regression analysis suggested that the individual difference variables accounted for 14%, 25%, 39%, and 30% of the variances of four EUC success variables, satisfaction for outcome, satisfaction for ability, frequency of computer use, and the number of tasks, respectively. Theses empirical findings suggest that EUC managers should consider individual differences of end-users in managing EUC, such as education, training support, and human resource management, to maximize potential benefits of EUC.

Background: This study clinically evaluated the effect of botulinum toxin type A (BTX-A) in the temporomandibular disorder (TMD) treatment using Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Methods: A total of 21 TMD patients were recruited to be treated with BTX-A injections on the bilateral masseter and temporalis muscles and were followed up by an oral and maxillofacial surgeon highly experienced in the TMD treatment. For each patient, diagnostic data gathering were conducted according to the RDC/TMD. Characteristic pain intensity, disability points, chronic pain grade, depression index, and grade of nonspecific physical symptoms were evaluated. Wilcoxon signed-rank test was applied for statistical analysis. Results: The results showed that more than half of the participants (85.7 %) had parafunctional oral habits such as bruxism or clenching. In comparison between pre- and post-treatment results, graded pain score, characteristic pain intensity, disability points, chronic pain grade, and grade of nonspecific physical symptoms showed statistically significant differences after the BTX-A injection therapy (p < 0.05). Most patients experienced collective decrease in clinical manifestations of TMD including pain relief and improved masticatory functions after the treatment. Conclusions: Within the limitation of our study, BTX-A injections in masticatory musculatures of TMD patients could be considered as a useful option for controlling complex TMD and helping its associated symptoms.

Recently, the ratio of elderly in the population are fast growing due to socio-economical development and the better medical service. Proportionally, the health problems in elderly are increasing, too. Medical professionals must try so that the elderly have the better life through health promotion and disease prevention as well as disease treatment. This study evaluated the effect of walking exercise program on the cardiorespiratory function and the flexibility in the elderly women. The design of research was one group pretest-posttest design. The subjects were eleven elderly women over sixty years old to live in K-city, Kyonggi-do. The type of exercise was walking, which was the most popular exercise in questionnaire. The exercise intensity was 40％∼60％ of the target heart-rate by Karvonen's method and maintained by the heart-rate monitor. The exercise period was five weeks and the exercise frequency was three times per week. The exercise duration was forty minutes at first and gradually increased up to an hour. In order to evaluate the effect of walking exercise, we measured VO/sub₂ max, resting heart -rate, systolic/diastolic blood pressure, FVC, FEV/sub₁, the flexibility before and after the five week's exercise program. The data are analyzed by the paired t-test and Wilcoxon signed rank test using SAS package. The results are as follows : 1) The hypothesis that cardiorespiratory function will be improved was partly supported. In VO/sub₂ max（p＝0.0001）, resting heart-rate（p＝0.0030）, systolic/diastolic blood-pressure（p＝0.0387／ p＝0.0024）, there was significant difference. FVC and FEV/sub₁ were increased after the exercise, but there were no significant difference. 2) The hypothesis that the flexibility will be improved was supported. There was significant difference in the flexibility（p＝0.0140）. As the further study, it is necessary to reevaluate the effect with more refined design. We also need to try meta-analysis about the results of previous studies obtained in the experimental setting and compare our result obtained in the field setting with them.

Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

The purpose of this study was to investigate the historical changes of western men's underclothes in the first half of the 20C and analyze functions and features of men's underclothes. This study was to utilize many literatures in the analysis of historical changes of western men's underclothes. In the 1900's, the attached collar was giving place to the detachable, and the coloured shirt for day wear was becoming accepted. The correct wear fur various occasions was given. Double collar was the favourite for day wear. The dress-shirt protector worn over the dress-shirt front. Men preferred to vest and pants in one as a combined garment. In the 1910's, underclothes were permitting freer movement, but what was still more significant was the glowing inclination to reduce the layers which covered the body. The new conception of decency which was beginning to appear continued to characterize underclothing the symbols of social rank, expect for formal occasion, were declining. For day the white shirt was being displaced by the soft-fronted shirt. In the 1927-1930's, Underclothes were reduced in number, extent and thickness. Underclothing had lost two of its original function : it no longer preserved the warmth of the body, nor did it disguise its essential shape. Both sexes discarded the use of white underwear, In the 1930's, men saw an increasing preference for the coloured shirt. Combinations became increasingly popular and the singlet were displacing the under-vest in the 1930's. All undergarments were very commonly in natural colours. In the 1940's, for evening dress. shirt was plain linen front and square cuffs. Short trunks reached to mid-thigh, had a front waist yoke with three button fastening. Underclothes were pursued ease and activity.

The prevalence of undernutrition in hospital populations is known to be high. The presence of malnutrition is associated with depression, infections, sarcopaenia, falls, fractures, reduced autonomy and increased mortality. This study specifically examined the prevalence of malnutrition in patients aged 65 or older at the time of admission as determined by the Mini Nutritional Assessment (MNA) which has been a frequently used nutritional risk screening tools in detecting undernutrition in old people. This study was done for one hundred eight hospitalized geriatric patients in Seoul National University Bundang Hospital, Seoul, Korea. On admission baseline history, anthropometrics measurements, laboratory data and nutritional status by MNA were assessed. Length of hospital stay was obtained by reviewing medical charts. We used one-way analysis of variance to compare the differences in variables. Spearman's rank correlation coefficients were calculated for associations between MNA and variables. On admission, $22.3\%$ of patients were malnourished and $40.7\%$ were at risk of malnutrition according to the MNA. Percent of ideal body weight, anthropometrics data, albumin, and hemoglobin were lower in the malnourished patients (p<0.05). The malnourished patients stayed in the hospital 7.3 days longer, as compared with well nourished patients (p<0.05). Percent of ideal body weight, albumin, hemoglobin and total cholesterol were correlated inversely with nutritional status according to MNA (p<0.05). MNA can be used for nutritional assessment in Korean old people, because MNA significantly correlated with other nutritional assessment parameters, such as, anthropometric and laboratory data in hospitalized geriatric patients. The high prevalence of malnutrition in the elderly was observed and the presence of malnutrition on admission predicted a significant increase in the length of hospital stay in this study. Therefore further studies are needed to determine whether nutritional interventions in old people with low MNA scores can improve clinical outcomes during the hospital course.

This study analyzed the content of special selling events in internet shopping malls to establish academic standards for special selling events as tools for sales promotions and to suggest systematic guidelines for marketers designing special selling events. Based on a content analysis, the titles of special selling events from four internet shopping malls selling women's apparel were analyzed. A total of 692 titles were analyzed. The results are as follow. First, the contents categories of special selling events could be classified into two groups such as 'theme' and 'tool'. Season, product characteristics, style, advice/information, brand, annual/social events, and marketing events were the main content categories that came under the 'theme' group; in addition, the price benefit, free offers, product mix, and marketing technique were the main content categories that came under the 'tool' group. Each main content category was subdivided into several segment content categories. Second, most of the titles were composed of more than two segment content categories that involved various information and benefits; however, the portion of titles composed of only theme related content categories or only tool related content categories was substantial. Furthermore, the theme related content categories were more than the tool related content categories. Third, the usage frequencies of the contents categories were analyzed. The upcoming season, single brand, sale/discount, item/material/color, special price/lowest price, and period/time/quantity limits were the segment content categories that held a high rank. Forth, most of the factors that evoked the unplanned purchases of consumers were related to the content categories of special sale events.

In the field of 'Human Vibration', it has been interested subjects to make equal sensation curves related to translational and rotational direction of whole-body, hand-transmitted and head-transmitted vibration, etc. When we consider the vibration of a vehicle, the main factor is vertical whole-body vibration. Until now, most of equal sensation curves used to derive frequency weighting function had been made using Western people. However, because of the inherent differences (for example, characteristic and shape of body parts, muscular and cellular tissue) between the Western people and the Oriental people, equal sensation curves based on Oriental people might be required. Also, the weight differences between the samples which consist of average-weighted and over-weighted group might cause the difference of equal sensation curves. So, in this study, 20 male Korean people were used to find equal sensation curves subject to vertical whole-body vibration on seated posture. Among 20 males, an over weighted group consisted of 10 male persons and an average weighted group was the others. Integrating and analyzing the data of two groups, some of non-parametric tests such as 'The Wilcoxon Signed Rank Test' and 'The Mann Whitney U test' were used.

Visual demands associated with in-vehicle display usage and text messaging distract a driver's visual attention from the roadway. To minimize eyes-off-the-road demands, voice interaction systems are widely introduced. Under cognitively distracted condition, however, awareness of the operating environment will be degraded although the driver remains oriented to the roadway. It is also know that the risk of inattentive driving varies with age, thus systematic analysis of driving risks is required for the older drivers. This paper aims to understand the age-related driving performance degradation and visual attention changes under auditory cognitive demand which consists of three graded levels of cognitive complexity. In this study, two groups, aged 25-35 and 60-69, engaged in a delayed auditory recall task, so called N-back task, while driving a simulated highway. Comparisons of younger and older drivers' driving performance including mean speed, speed variability and standard deviation of lane position, and gaze dispersion changes, which consist of x-axis and y-axis of visual attention, were conducted. As a result, it was observed that gaze dispersion decreased with each level of demand, demonstrating that these indices can correctly rank order cognitive workload. Moreover, gaze dispersion change patterns were quite consistent in younger and older age groups. Effects were also observed on driving performance measures, but they were subtle, nonlinear, and did not effectively differentiate the levels of cognitive workload.
