In July 2002, a destructive stem rot of tawny daylily(Hemerocallis fulva) was occurred sporadically in exhibition farm of Gyeongsangnam-do Agricultural Research and Extension Services located in Hamyang-gun, Korea. The fungus also caused collar and crown rot, and systemic wilt or blight of whole plant. White mycelium spread over stems and petioles of infected plants and sclerotia were formed on the old lesions and near the soil surface. The optimum temperature for mycelial growth and scierotial formations was $30^{\circ}C$ on PDA. The mycelial width ranged $4.2{\sim}10.4{\mu}m$ and the color was white, usually many narrow mycelial strand grew in the aerial mycelium and formed clamp connection. The shape of sclerotia was spherical and $1.0{\sim}3.2$ mm in diameter. The fungus was isolated repeatedly from the infected tissues and confirmed its pathogenicity to Hemerocallis fulva and identified as Sclerotium rolfsii. This is the first report on the stem rot of H. fulva caused by S. rolfsii in Korea.

This study was intended to make an inquiry into the effect of lines, shapes and colors (achromatic colors) as apparel design elements on the perceptions of facial size, brightness and shape through an empirical research based on the theories of visual perception and optical illusion that have been studied in Gestalt Psychology, which becomes the basis of apparel design principles. It was shown that the facial size was influenced by the collar size, the degree of neckline cut, and the thickness of the trimming line. The white scarf with the white jacket made the face look darkest while the black scarf with the black jacket made the face look brightest. When the neckline had the characteristic of the line contrasted with the facial shape, the oval-shaped face was perceived to be the most ideal. When the facial shape and the neckline shape were similar, the facial shape was perceived to be more highlighted.

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.

An effective strategy for obesity intervention should include demographic, health-related, and work-related factors that are most relevant to the target population. Factors most strongly associated with obesity may differ for groups of individuals across industries or age categories. The purpose of this study was to provide current knowledge about the possible association between psychosocial job stress and immune parameters in blood. We assessed obesity-related parameters as well as the natural killer cell activity (NKCA) in female workers. There was a significant difference in the obesity-related blood parameters, i.e. fasting blood sugar level, according to age (p<0.05). Moreover, it showed a significant difference in NK cell activity between the obese and non-obese factor groups (p<0.05). Pearson correlation analysis demonstrated that NKCA was closely correlated with obesity related factors. In the future, it would have to study the biological changes which increase the activity of the immune factors to the immunological response.

PURPOSE: Forward head posture (FHP) is one of the most common postural problems among white-collar workers who perform highly repetitive tasks in the same position. The aim of this study was to research the effects of thoracic and lumbar support fixtures on forward head posture (FHP) during visual display terminal (VDT) work. METHODS: The subjects were 36 healthy male students with no problems in their medical history or respiratory systems. The subjects were randomly assigned to three groups: control group (n=12), thoracic support fixtures (n=12), and lumbar support fixtures (n=12). We conducted a text typing task of the same content for 20 minutes, and evaluated the angles, including the craniovertebra angle (CVA), craniorotation angle (CRA) with photogrammetry. RESULTS: The thoracic and lumbar support fixture groups showed a statistically significant difference at the CVA and CRA to the control group (p<.05), and the post-hoc test showed an increase of the CVA and decrease of the CRA than the control group. However, when we compared the effects of thoracic and lumbar support fixtures on FHP, there was no significant difference in the difference in decrease of the CVA or increase of the CRA (p>.05). CONCLUSION: We determined that VDT work using thoracic and lumbar support fixtures has a positive effect on forward head posture in white-collar workers. Further studies are required to find the more effective location of support fixtures.

Well-balanced meal is very important in its quantity and quality. Especially on the quantity field it becomes difficult for a foodservice operation to decide proper portion for individuals uniformly. These study was focused to setting up a proper portion by each food service operation. The results obtained were: 1. Individual consumption size from dormitory food service of college: cooked rice 282 g, soups 161 g, pot stewes 162 g, stir fries 53 g, stews 32 g, kimchies 47 g, fresh and boiled salads 43 g, one course dishies 477 g, pan broiles 44 g, meunieres 124 g. Individual consumption size from industry foodservice (white collar worker): cooked rices 228 g, soups 205 g, pot stewes 251 g, stir fries 20 g, stewes 76 g, kimchies 57 g, fresh and boiled salads 36 g, one course dishies 423 g, pan broiles 63 g, meunieres 38 g. 2. Proper portion of meal based on a statistical data is as follows: at college foodservice - cooked rices $280{\sim}290$ g, soups $155{\sim}170$ g, pot stewes 170 g, stir fries 60 g, stewes 35 g, kimchies $40{\sim}60$ g, fresh and boiled salads 50 g, one course dishies 480 g, pan broiles 50 g, meunieres 130 g and at industry foodservice (white collar worker) - cooked rices $220{\sim}250$ g, soups 210 g, pot stewes 250 g, stir fries 20 g, stewes 80 g, kimchies 60 g, fresh and boiled salads 40 g, one course dishies 430 g, pan broiles 70 g, meunieres 40 g.

This paper investigates the employment and wage structural changes that have occurred around the economic crisis in 1997. We propose a theoretical model for external effects of human capital within firms and provide their estimation. When the employment and wage structural changes are considered simultaneously, labor demand decreases seem to more than offset labor supply changes during the period. While educational human capital, human capital accumulated with firm-tenure, human capital of married workers and of white-collar workers are considered to have positive external effects, human capital of relatively-old workers and managerial workers are considered to have negative external effects. We suggest that while employment restructuring with regard to age, tenure, and education and managerial workers during the period have improved the efficiency of firms, those with regard to married and white-collar workers have not.

AIDS (Acquired Immunodeficiency Syndrome) known as 20th century's pest is spreading rapidly internationally, and the number of patients are increasing. Since the prevention vaccine has not been developed yet, the only available effective method for preventing AIDS is the health education. Most of the AIDS-infected persons are males, and especially over twenties of age. Therefore, it is necessary to measure the knowledge and attitudes on AIDS of male workers. The purpose of this study is to examine the knowledge, attitudes and education-needs of male workers on AIDS. The data were collected by a questionnaire survey of 977 workers who work in Seoul and Kyungki areas from September 1 thru October 4, 1997. The results were as follows: 1. We examined the level of knowledge on AIDS transmission, symptoms, diagnoses, and prevention methods. Even though respondents had a moderate level of AIDS-related knowledge, still sizable numbers believed that AIDS could be transmitted through casual contact. White-collar workers, higher education groups, higher income groups or those with age thirties showed respectively higher level of knowledge than the other comparison groups. 2. 85％ of the respondents recognized AIDS as a serious problem. Statistical analysis revealed that white-collar workers, higher education groups or those with age twenties had more positive attitudes towards a AIDS patient than their counterparts. 3. Over 80％ of the respondents replied that AIDS education in schools, work places, social agencies or by mass-media was necessary. 62.8％ of the respondents mentioned that government should play the major role in developing AIDS education program. 4. The prediction model of AIDS-education needs was examined with using the multiple logistic regression method. The education level and AIDS-related knowledge were turned to be statistically significant factors influencing positively the perceived needs of AIDS education.

The objectives of this study were to investigate the relation between personality(activity, emotional stability, and dominance) and clothing design preferences, and to examine the differences of clothing design preferences according to demographic variables of men. Subjects for the study were 255 male white-collar workers ranging in ages from twenties to fifties, in Seoul and Kwangju City, Korea. The men with higher activity of personality preferred the double jacket with 4 buttons, the combination of light color jacket and dark trousers, glen check pattern jacket, herringbone pattern jacket, light beige color dress shirts. The higher the emotional stability, the higher the preferences on diverse patterns such as fine stripe, plaid, hound\`s-tooth check, and small check pattern. The men with higher dominance preferred dark blue color suit, glen check pattern suit, and necktie of red circle, and disliked the necktie of gray circle. The men in their 20\`s and 30\`s liked the single jacket with 3 buttons, the suit of fine stripe and the necktie of gray circle more among three income groups. The higher the men\`s age and income were, the more they liked the conservative style such as a single jacket with 2 buttons. The men who reside in Seoul liked the suit of gray circle, the jacket and trousers of same color, the patternless jacket, and the patternless suit more than the men in Kwangju. Therefore, the men in methropolitan area preferred conservative clothing image. Fine stripe pattern and patternless materials were preferred when men wore jacket and trousers of same color, while glen check pattern was preferred as the pattern of jacket when jacket and trousers of different color. Male white-collar worker liked single jacket more than double jacket, and preferred the dark blue color suit and necktie, patternless suit, fine stripe suit, and the pale blue dress shirts generally. The present findings provide that the personality of male has influence on the clothing design preferences, and it is possible to infer men\`s personality by their attire.
