The purpose of this study is to examine features of parts of Jikryung and relations among the features. Results of the study can be described as follows. 1. The short front and long rear of Jikryung was changed into the long front and long rear of the dress in the late 16th century. Kalgit of quasi-square style as double collar was changed into that of common collar in the late 16th century and then into common semi-circle collar in the early 17th century, when double Sup was also changed Into single Sup. Narrow sleeves of Jikryung were replaced by bean chaff-shaped in the late 16th century and then by wide ones in the early period of the next century. The shape of the side hem of Jikryung was changed from rectangle into trapezoid in the early 17th century Triangle-shaped Moo was changed into trapezoid-shaped one in the late 16th century and then again into triangle in the late 17th century 2. Changes in shapes of the parts of Jikryung were made with them correlated. The collar of Jikryung saw change in its form from double to common as its width was reduced. Double Sup was changed into single one and the narrow, short coat string into the long one as Jikryung became a dress needing less adjustment. The sleeves widened as the length of whajang increased. The side hem of Jikryung saw change in its shape from rectangular to trapezoidal one as its position was changed. Trapezoidal Moo was replaced by triangular one as the sleeve of Jikryung was changed in shape. 3. Changes in shapes of the parts of Jikryung influenced the aesthetic beauty of the dress itself In its first period, Jikryung was simple with long, slim silhouettes. In its second period, the dress was rich with increased volume. Finally in its third period, the dress was characterized by the harmony of simpleness and richness.

We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21-80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1-2, n = 96), and MetS (MetS $RF{\geq}3$, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of seafoods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.

Objectives: This study aimed to compare the factors of dietary and health behavior according to the employment in women in early adulthood and to analyze their relationship. Methods: In this study, adult women aged 20~29 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2016~2019 were classified into two groups depending on their permanent worker status, namely tenured employees (n = 254) and temporary employees (n = 377). Dietary habits (prevalence of skipping meals, food nutrition label use, etc.), nutrient intake, and metabolic syndrome factors were analyzed. Results: The tenured employees' group showed a significantly lower proportion of subjects who skipped breakfast (P = 0.0254) and significantly higher daily energy intake (P = 0.0264) than the temporary employees' group. However, there were no significant differences in the intake of energy nutrients and most of the micronutrients per 1,000 kcal of energy intake between the two groups. The proportion of subjects who consumed energy nutrients under 75% of the estimated energy requirement (EER) was 38.11% in the tenured employees' group, which was significantly lower than the 48.30% in the temporary employees' group (P = 0.0159). In economically active women aged 19~29 years, the odds ratio of low HDL-cholesterolemia prevalence was 1.80 times higher (95% CI, 1.06-3.06) in the temporary employees' group compared to that in the tenured employees' group after adjustment for confounding factors (P = 0.0295). Conclusions: In conclusion, among Korean adult women in their twenties, temporary employees showed inappropriate eating habits such as skipping breakfast, and had abnormal blood lipid levels.

Background: In the early stage of the coronavirus disease 2019 (COVID-19) epidemic, small- and midsized enterprises (SMEs) may be an important transmission consideration. The study aimed to identify the pattern of COVID-19 prevention measures during the outbreaks in Daegu and Gyeongsangbuk-do at the early stage of COVID-19. Moreover, we investigated whether SME size and past experiences affected the preventive measures implemented in the region. Methods: A survey detailing the general characteristics and implementation of 12 preventive activities was conducted in 122 SMEs in Daegu and Gyeongsangbuk-do. The survey was analyzed by size and operation period. Results: The study subjects consisted of 53 (43.4%) workplaces with 1-5 employees, 50 (40.9%) workplaces with 6-30 employees, and 19 (15.6%) workplaces with 31-49 employees. The lowest three items among those surveyed were 'symptomatic workers to stay home for 3-4 days' (17.2%), 'work remotely' (18.9%), and 'video meetings' (20.5%). There were significant differences in the rate of several preventive measures implemented. The larger sized SMEs, the higher the number of implementations (p < 0.01). The operation period had no significant relationship with the implementation of preventive measures. The same pattern was observed in multiple generalized linear regression with covariate adjustment. Conclusion: Preventive measures among SMEs with fewer than 50 employees were identified. Even within SMEs, a gap in preventive measures according to size was confirmed. To prevent the spread of infection and protect workers' right to health, different support for different sized SMEs is necessary.

This paper investigated the temperature history of mass concrete mock up structure considering different heat generation by varying with mixture proportion. Setting time difference between high early strength mixture (E-P) and retarding mixture (R-F30) was 14.5hours. Incorporation of $30\%$ of fly ash contributed to $10^{\circ}C$ of hydration heat reduction. In generally used C and D combination, bottom concrete shows earlier hydration, while E-J combination showed reverse tendency and thus, this method can reduce the crack occurrence. Therefore, heat generation difference method has beneficial effect on reducing crack induced by hydration heat resulting from heat generation difference between surface and center section.

The Multiethnic Cohort Study was designed to study prospectively the relationship of diet and other lifestyle factors to the risk of cancer. The cohort was established in 1993-1996 in Hawaii and California (primarily Los Angeles) and included a representative sample of more than 215,000 men and women primarily from five different ethnic groups: Japanese, whites, Native Hawaiians, Latinos, and African- Americans. Because of the emphasis on diet, great attention was paid to developing and pre-testing a self-administered quantitative food frequency questionnaire that would adequately assess food and nutrient intakes in these groups. An extensive food composition database was also created for the study. In addition, during data collection, a calibration study was conducted that makes possible adjustment for measurement error in nutrient intakes and valid comparison of intakes across the several ethnic groups. At the present time, blood and urine specimens are being collected from cohort participants and should yield a biorepository of more than 80,000 subjects. Baseline data indicate that the cohort is well representative of the general population of Hawaii and California, so that results can be generalized. These data also show a wide range in dietary intakes and in other lifestyle variables that should facilitate the testing of etiologic hypotheses.

Medical risk selection or mortality analysis is very important in insurance medicine. Among many kind of source articles there have been several limitations. There are few long-term follow-up studies in rare disease, as Romeo's article. We can do mortality analysis of this type using cause of death within the article and assumption of expected mortality q'. In the case of article which is published in foreign country such as Tikkanen et al, we can use comparative group from the control group within source article. It is another way for mortality analysis of limited article. However Retrospective study even performed in Korea, is unusable for estimation of extra-mortality.

This paper presents the result of adiabetic temperature rise and fundamental properties of concrete combining admixtures. According to results, difference of setting time with I5.5hours is observed between S-P and R-F30 mixture. Based on the adiabetic temperature rise test, 8$^{circ}C$of heat producted occurs between E-P and R-F30 mixture. is applied to estimate the temperature rising under adiabetic curing condition, which exhibits closer consistency with tested value. The function mentioned above can account for the effect of dormant period in hydration process at early stage on hydration heat production. It reveals that the consideration of placing layer based on the mixture adjustment(E-P mixture at top layer and R-F30 mixture at bottom layer) in mass concreting will contribute to reduce hydration heat as well as alleviate tensile stress discrepancy between placing layer.
