Introduction: There is a growing global interest in the issue of precarious employment. We aimed to analyze the characteristics and socio-demographic distribution of precarious employment using a summative score approach. Methods: To operationalize precarious employment, we utilized data from the Korean Working Conditions Survey and focused on three distinct dimensions: employment insecurity, income inadequacy, and a lack of rights and protections. By constructing a summative scale ranging from -16 to 2, with lower scores indicating higher precariousness, we measured employment precariousness among Korean wage workers. To compare employment precariousness according to survey participant characteristics, we employed the Wilcoxon Rank Sum Test. Results: We analyzed a weighted number of 38,432 workers. The overall sample showed a median (Q1, Q3) summative scale score of -3 (-6, -1). The median summative score was lower for women compared to men (men: -2; women: -5; p < 0.001), as well as for young or older workers compared to middle-aged workers (young: -4; middle-aged: -2; older: -5; p < 0.001). Similarly, workers with lower educational levels (middle school or below: -8; high school: -5; college or above: -2; p < 0.001) and non-white collar workers (blue collar: -5; service/sales worker: -6; white collar: -2; p < 0.001) experienced higher levels of employment precariousness. Conclusion: Our findings indicate that certain vulnerable groups, such as women, young or older adults, workers with low educational attainment, and caregiving or low-skilled elementary workers, are disproportionately exposed to high employment precariousness. Active policy interventions are needed to improve the employment quality of vulnerable groups.

In order to investigate the function and feature of western men's underclothes in the second half of the 19C, in this study, the historical changes of western men's underclothes are compared the first half of the 19C with the second half of the 19C. In the second half of the 19C, the useful function to ease for body was important. In the 1860's, for day-shirt, the tucked panels was disappeared and the front was pain. But the evening dress-shirt continued to show an expansive front tucked. Coloured shirts was used for country and sporting occasions. Ready-made underwear was used. In the 1870's, the plain breast was introduced and the Gladstone collar was used. Paper collars and dickeys were unfashionable. The drawers was composed a gusset at the back of the waistband. The dress of one generation was became the livery of the next. In the 1880's, a new feature was one stud and the use of pique for the breast. Coloured shirt was composed of stripes across the breast. In the 1890's, height of the collar steadily increased. The coat-shirt and regatta shirt became popular. The nice choice of shirt, collar and tie was a matter of supreme importance .The social status of the white shirt was further threatened by fancy coloured shirts. The mode of relaxation affected sports shirts. By the close of this period, both sexes accepted the hygienic rule of wool next the skin.

Cave 79 of Kumtura grottoes, is the best preserved cave, which has an important meaning for research on Uighur costume. This paper is intended to analyze the costume characteristics of female donors in Cave 79 by comparing image materials between Dunhuang murals and other murals in Xinjiang province. In Cave 79, female donor wears red robe with tight sleeve, whose collar is crescent-shaped decorated. Two different opinions are upheld for this decoration. One regards this as the turn-down collar, while the other believes this as decoration on V-neckline. Red robe is quite common in female donors of Xinjiang and Dunhuang murals and a female in fresco is wearing a crown in a triangle red headwear style, regarded as red silk and drooping at head. Female donors wear an extra coat, kame hair clasp, red jacket, light-colored high-waist skirt with a long-tail waistband, and tangerine Pibo (silk ribbon) with scattered small flowers. All these costume styles are commonly-used by Han females. The kame headwear is also the common ornament for Han females and the female's hairstyle is in cone shape on head by a white kame. Current costumes are similar but not completely same.

Background: This study analyzed the drought responses of five forest tree species grown in Korean peninsula, Korean fir Abies koreana (Ak), eastern white pine Pinus strobus (Ps), keyaki Zelkova serrata (Zs), tulip tree Liriodendron tulipifera (Lt), and Japanese elm Ulmus japonica (Uj). Physiological (chlorophyll, root collar diameter [RCD]) and biochemical responses (non-structural carbohydrates, proline, lipid peroxidase and abscisic acid [ABA]) of the plants grown under mild (MD) and severe drought (SD) were compared. Results: In this study, three soil moisture regimes: control (100% precipitation), MD (60% reduction in precipitation) and SD (20% reduction in precipitation) were applied. Soil moisture content showed high water content in control site compared to MD and SD. A decline in RCD was found for Korean fir, keyaki, and tulip plants, with eastern white pine and Japanese elm showing no significant decline to the prolonged drought exposure (both MD and SD). Total chlorophyll showed a significant decline in Korean fir and tulip, with the sugar levels indicating a significant increase in Korean fir and keyaki species under SD compared to control plants. Non-significant decline in sugar level was noted for eastern white pine and Japanese elm. High accumulation of ABA, malondealdehyde and proline was noted in Korean fir, tulip, and keyaki under SD compared to control. Signs of tree mortality was only observed in Korean fir under MD (38%) and SD (43%). Conclusions: The observed findings indicate the drought responses of five tree species. The majority of the morpho-physiological (especially mortality) and biochemical variables assessed in our study indicate superior long-term drought resistance of Ps and Uj compared to the highly sensitive Ak, and moderately sensitive Lt and Zs. The results provided will help species selection for afforestation programs and establishment of sustainable forests, especially of drought-tolerant species, under increased frequency and intensity of spring and summer droughts.

A destructive collar rot of Doonggulle (Polygonatum odoratum var. pluriflorum) occurred in an experimental farm at Hamyang Medicinal Plant Experiment Station, Kyonguam ARES in 1999. The disease also observed in farmer's fileds in Hamyang and the infection rate reached up to 12.3%. Upper parts of the infected plants were mostly blighted and white mycelial mats were formed on the lesions or soil lines near the stem. The fungus readily formed sclerotia on PDA and then shapes were globoid or irregular, and sized $0.9{\sim}6.8{\times}0.6{\sim}5.2\;mm$ (av. $2.7{\sim}2.3\;mm$). Although the fungus showed wide range of mycelial growth temperature, the optimum temperature was about $30^{\circ}C$. The typical sclerotium type and clamp connections of hyphae were found in the fungus grown in PDA. The causal fungus was identified as Sclerotium rolfsii on the basis of mycological characteristics and pathogenicity that on the host plants. This is the first report on the collar rot of Polygonatum odoratum caused by Sclerotium rolfsii in Korea.

A destructive collar rot disease was found on broad bean (Vicia faba) in several farmer's field located in Changseon-myon, Namhae-gun, Gyeongsangnam-do in 2001. The typical symptoms of the disease were stem rot, crown rot, wilt or blight. Upper parts of the infected stems were mostly blighted and white mycelial mats were spread over lesions and the sclerotia were formed on the stems near soil line. The infection rates of the disease in the surveyed area were ranged from 28.6 to 42.8%. The sclerotia of the fungus readily formed in artificial media such as PDA at $30^{\circ}C$ and its shape was globoid or irregular and size was $1.0{\sim}3.7{\times}1.0{\sim}2.8\;mm\;(av.\;1.0{\sim}2.3\;mm)$ and was brown or dark brown in color. The optimum temperature for growth of the fungus was about $30^{\circ}C$. The typical clamp connections were found in the hypha of the fungus grown on PDA. On the basis of mycological characteristics and pathogenecity test on host plants, the fungus was identified as Sclerotium rolfsii. This is the first report on the collar rot of broad bean caused by Sclerotium rolfsii in Korea.

Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to achive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers 'Motive-Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive(55.1%-28.2%) and action(38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher artier level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment(salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

The study aims to evaluate job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms of the ordinary white-collar worker. The subjects of the study were 83 workers who were working D Health Center and Dgu office of Gwangju Metropolitan City and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from three subjects whose responses were insincere of 102 ones were decided for the final analysis. The results showed that there were significant differences in all job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms. Depression, self-efficacy, job stress were significantly correlated; however, health related to quality of life was not. Therefore, as the results indicate that job stress, self-efficacy, depression and health-related quality of life can be affected by musculoskeletal pain for office workers, there is a need for the development of programs focused on the prevention of musculoskeletal discomfort.
