In this research, consumer awareness investigation and wearing test were carried out for obtaining useful data on the development of thermo-sensitive functional clothing material. A survey involved 216 people in Seoul and Kyeonggi- do, and 200 questionnaires data were analyzed by descriptive statistics and frequency using SPSS 17.0. Four healthy men in twenties were participated for wearing test. Subjects in normal loungewear were exposed to temperature change from the initial temperature 30oC down to 5oC for an hour in a climate chamber. The environmental temperature, surface temperature of garment and skin were measured. As a result, most of respondents have all season clothing products such as underwear, hosiery, and jogging suit for loungewear. Also, thermo regulator y functional clothes are frequently used as underwear and sweat shirt. The consumer awareness investigation on thermo regulatory functional clothing showed that the most important key buying factor is quick climate temperature response, easy maintenance, design and cost, in that order. Surface temperature of garment went down with the cooling down of environmental temperature. The lower environmental temperature, the greater temperature difference by body part showed. Skin temperature change by environmental temperature showed similar tendency of garment surface temperature. In comparison between garment surface and body skin, temperature difference became larger under the lower environmental temperature.

This study aimed to isolate wild yeasts obtained from flowers and soil of the Wolpyung park, Daejeon city and Gykpo beach, Buan, Jeollabuk-do in Korea, and to further characterize previously unrecorded wild yeast strains. In total, 88 strains of 62 different species of wild yeasts were isolated from 75 samples obtained from the Wolpyung park. Among these, six strains of Trichosporon moniliiforme and four strains each of Papiliotrema flavescens and Candida melibiosica were isolated. Additionally, 39 strains of 30 different species of wild yeasts were isolated from 35 samples collected from the Gykpo beach. Among the 127 isolated wild yeast strains, 10 strains, including Apiotrichum porosum ASCM32-1, were previously unrecorded. All the 10 previously unrecorded yeasts were oval or global in shape, and three strains, including Candida athensensis WP4-90-3, formed spores. Three strains, including Vishniacozyma taibaiensis WP13-2, were halophilic yeasts which grew in 15% NaCl-containing YPD(yeast extract-peptone-dextrose) medium. Five strains, including C. athensensis WP4-90-3, showed 15% ethanol resistance. Cell-free extracts from Candida oleophila WP5-19-1 and Wickerhamomyces anomalus HO9-2 showed the highest β-glucuronidase inhibitory activity (49.0%) and neutrophil elastase inhibitory activity (38.4%), respectively.

Background: The number of children and adolescents has decreased by more than 3 million over the past 10 years. We analyzed changes in the number of children and adolescents with complex chronic conditions (CCCs) and their medical expenditures between 2011 and 2021. Methods: We used National Health Insurance claims data of patients under the age of 20 from 2011 to 2021. CCCs were classified as pediatric CCCs by Feudtner et al. Patients who repeatedly utilize medical services due to CCCs were defined as patients who sought medical care twice or more within the past 3 years. Their sex, age, CCC categories, and the number of CCC categories were presented using descriptive analyses. Results: The number of children and adolescents with CCCs increased from 345,320 (3.04%) in 2011 to 451,238 (5.33%) in 2021. Patients who repeatedly utilized medical services due to CCCs increased by 71,889 during the same period. The proportion of patients with two or more CCC categories increased from 35.80% in 2011 to 43.67% in 2021. In 2021, patients with other congenital or genetic defect were most common. Medical expenditures associated with CCCs increased from 475,654 million won (12.34%) in 2011 to 768,467 million won (19.11%) in 2021. Conclusion: The number of patients with CCCs and their medical expenditures increased in Korea between 2011 and 2021. The results indicate that consistent national efforts are required to maintain the specialized pediatric care. Further studies are needed to identify pediatric patients who require specialized medical services through various methods.

Hypwelipiswmia is commonly observed in the diabetics, especially with cardiovascular complications. We studied lipid profiles and cardiovascular complication in the 191 adult onset DM patients. The results are as follows: 1. The age distribution was from 24 years old to 82 years old. Male patients were 99 persons, famale patients were 92 persons. The mean disease duration was less than 2 years in the 77 patients, more than 5 years in the 79 patients. 2. Upon the classification between sexes, the mean age was 55±1(SEM) years in the male group, 53±1(SEM) years in the female group. The mean disease durtion was 6.4±1(SEM) years in the female group, longer in the male group (P<0.05). The triglyceride level was 210±16(SEM)㎎% in the male group, 214±13(SEM)㎎% in the female group. The fasting blood sugar level was 147±6(SEM)㎎/dl in the male group, 158±8(SEM)㎎/dl n the female group. The cholesterol level was 229±5(SEM)㎎/dl in the male group, 248±5(SEM)㎎/dl in the female group, higher in the female group (P<0.05). 3. The cardiovascurlar complicatioin (Hypertension, Myocardial infarction, Myocardial ischemia, Angina, Gangrene, Proliferative retinopathy) were present in the 60 patients from 191 patients. Hypertension was present in the 48 patients, and the most prevalent. The mean age and carrdiovascular complication were higher in the more than 5 years of mean disease duration group(mean age 57.99±1.14(SEM)㎎ year) than less than 5 years group(mean age 52.12±0.10(SEM)㎎ year) (P<0.001, P<0.01). 4. The mean disease duration (7.40±1.01(SEM) years), mean triglyceride levels(271±1.01(SEM)㎎%), and mean cholestrerol levels( 257±8㎎.dl) in the cardiovascularly complicated group were higher than those of non-complicated group (P<0.01). 5. The triglycerdie level was high in the obese group (230±14SEM㎎%) than non-obese group (184±15SEM㎎%) (P<0.05). The obese patients were more prevalent in the female group than male group significantly. 6. Considering obesity and cardiovascular complications, the triglyceride value was higher in the obese complicated group(300±30SEM㎎%) than obese non-complicated (197±14SEM㎎ %) or non-obese non-complicated (168±13SEM㎎ %) group (P<0.001). The cholesterol level was higher in the obese complicated group (267±10SEM㎎/dl) than obese non-complicated (230±5SEM㎎/dl) or non-obese non-complicated group(229±7SEM㎎/dl) (P<0.05). 7. Classifying upon insulin response pattern, the obese patients were found in the response pattern, low response pattern, flat type pattern(no response pattern) in the decreasing number of order (P<0.01). The cardiovascular complications were found in the low response group, response group, and flat type pattern (no response) in the decreasing number of order ( P<0.05). The combined cases of obesity and cardiovascular complications were found in the low response group, response group and flat type group(no response) pattern in the decreasing number of order (P<0.01). The mean disease duration was longer in the flat type group (no response) (4.48±0.6SEM years) than the response group(2.43±0.90SEM years) (P<0.05). The mean triglyceride value was higher in the response group (267.38±154.75SEM㎎%) than the flat type(no response group) (198.35±154.05SD㎎%) (P<0.05). So, we conclude that in the NIDDM, obesity control(die control, ideal body weight mainterice, and hyperlipidemia control) is essential for better DM control and cardiovascular complication control.

The side-chain alkylation of toluene with methanol was studied experimentally over cation-exchanged X and Y zeolites. According to the experimental results, the higher conversions have been obtained at 420℃ and reactant mole ratio=6(toluene/methanol) and over K-exchanged X-zeolite, the yields of styrene and ethylbenzene were 5.7%, 4.4% respectively that were remarkably higher compared with those over KY-zeolite, and also the yield of products over KX-zeolite was higher than over CaX-zeolite since the potassium ion over X-zeolite enhances the catalytic due to its basic tendency compared with the calcium ion. The reaction path was suggested for this reaction using both the acidic and basic sites on the surface.

According to the increase of the number and portion of the elderly people, the elderly housing is an important social welfare factor as the solution of the elderly problem. When we consider the elderly housing of Korea, it should be appropriate to Korean culture and emotion. This study aims to suggest two ways of Korean elderly housing: three-generation housing and the renovation of housing which one elderly person have lived in. Considering that family centrism is remained a lot in Korean consciousness, those two ways should be developed well so as to build a unique Korean housing culture for the elderly.
