질소비료를 $3{\sim}7$회 분시하여 옥로차의 수량 및 품질을 분석한 결과는 다음과 같다. 5회 분시가 타처리에 비해 생육과 수량이 많고 타처리에 비해 총질소, 총아미노산, 비타민C 함량이 약간 많았으며 탄닌, 카페인, 엽록소, 총유리당 함량은 3회분시를 제외하고 $4{\sim}7$회 분시에서 거의 차이가 없었다. 지방산 함량은 $2,888{\sim}2,933mg/100g$이었고, 특히 5회 분시에서는 oleic acid, linoleic acid, linolenic acild 함량이 가장 많았다. 옥로차 감칠맛 성분인 theanine을 포함해 16종이 아미노산을 분리 정량한 결과 5회 분시가 타처리에 비해 theanine 함량이 $72{\sim}513mg/100g$더 많았다. 관능평가에서 3회 분시가 80.2점으로서 다른 처리보다 낮았고, 5회 처리가 84.7점으로 가장 높았다. 결론적으로 5회 분시처리가 다른처리에 비해 수량도 양호하고 차 품질도 우수하여 옥로차의 적정 분시첫수라고 생각된다.

This study was conducted to find out the relationship between the stress perception and health habits with 426 industrial workers using the GARS(Global assessment of recent stress) scale. The results were as follows : 1. The mean scores of stress perception were higher in female, more educated and divorced. There were no evident trends of mean scores of stress perception in age, monthly income and years worked. 2. The stress perception by health habits and sex showed significant difference in physical exercise and smoking variables. The higher health bit index, the lower degree of stress perception in male, but higher in female reversely. 3. The health habits and demographic variables were classified by five factors. Factors of sleeping hours, body mass index, and taste containing smoking and alcohol drinking had relatively high relation to stress perception. The explanation power of factors and variables was relatively low as 3.4%.

The purpose of this study was to measure consumption values and to investigate the differences in the process of decision making when purchasing apparel products among groups divided by consumption values. A self-administered questionnaire was distributed to 550 subjects in their 20's and 30's from Sepember 29th to October 25th in 2001; 463 were used for the data analysis. The results of this study were as follows; Consumption values were classified into five factors: Practical/functional value, Social/conformitive value, Subjective/aesthetic value, Epistemic value and Conspicuous value. Subjects were classified into 4 groups based on consumption values: the Conspicuous, the Epistemic, the Social/conformitive and the Indifferent. There were significant differences among the four groups in selected motives in the problem recognition process. Significant differences were found among the groups in own taste & personality in the information search process. Significant difference were also found in the importance of design, color, price, coordination, fashion and self-image in the alternative evaluation process.

The principal objective of this study was to evaluate the quality characteristics of black garlic milk tofu prepared with five different levels (0%, 0.5%, 1%, 1.5%, and 2.0%) of black garlic concentrate (BG0~BG4). We conducted the pH, total phenol and flavonoids, Hunter's color values, mechanical characteristics, and a sensory evaluation analysis of black garlic milk tofu. The total phenol and flavonoid content of black garlic concentrate were 1.67mg/100 g and 1.07 mg/100 g. The more black garlic concentrate increased, the more lightness (L) decreased, but redness(a) and yellowness (b) increased. The hardness, gumminess, and chewiness scores significantly increased (p<0.05) in all black garlic milk tofu samples. In color, taste, flavor, texture, and overall quality, the score of milk tofu with 1.0% black garlic concentrate (BG2) increased the most.

The purpose of this study was to evaluate the effects of soybean varieties on the physicochemical and sensory characteristics tofu. Five varieties of soybeans(Daewon, Jinpoung, Hwanggum, Jinmi, and Manni) were selected for these experiments. Proximate composition and total phenolic acids in the soybeans, and the moisture, turbidity, lightness, yield rate, texture characteristics, and sensory characteristics of the tofu were measured. The Hwanggum soybeans had the highest levels of crude lipid and crude ash. There was a significant difference in the moisture and yield rate of the tofu(p<0.05). The crude protein and crude lipid contents of the soybeans affected the hardness and springiness of the tofu. In sensory evaluations, significant differences(p<0.05) were shown in taste, texture, and overall acceptability depending on the tofu by soybean variety. Therefore, one should consider soybean varieties when manufacturing tofu.

The purposed of this study was to investigate the dimensions of clothing purchasing motives and to examine differences of these dimensions according to the demographic variables, and to examine the relationship between the clothing attitudes and clothing purchasing motives. The subjects selected for the final analysis were 595 adults rainging from 20's to 40's in age. As for the analytic method. Cronbach's $\alpha$, factor analysis, one-way ANOVA, Tukey's multiple range test, frequency and percentage were applied. The conclusions of this study were as follows: 1. The clothing purchasing motive was classified into five dimensions: advertising and promotion, finding of clothing meeting one's own taste, extra income, practical purchasing needs and impulse purchase. And the dimensions of clothing purchasing motive were significantly different according to monthly expenditure on clothing, sex and educational level. 2. The relationship between the clothing attitudes dimensions and clothing purchasing motive dimensions were significant.

Mushrooms are known for their various attributes in the fields of nutrition and therapeutics. With exceptional taste, aroma, and nutritional value, they are considered 'functional food'-improving health and providing nutritional benefits to the body. Mushrooms have also been widely applied therapeutically as they possess diverse bioactive compounds known as secondary metabolites. These secondary metabolites demonstrated diverse biological properties such as anticancer, anti-diabetic, immunomodulatory, antimicrobial, anti-inflammatory, antiviral, anti-allergic, and antioxidative activities. This review presents bioactive compounds from the field of mushroom metabolite research and discusses important findings regarding bioactive compounds identified during the last five years (2015 - 2019).

재내식 발효법에 협사한 조건하에서 맥주를 더욱 방률적으로 생산하기 위하여 발효개시 3일후에 일정양의 새로운 맥즙을 첨가시키고 나머지 발효를 4일내지 6일사이에 완성시켜 보았다. 그 결과 1/3 용량과 $\frac{1}{2}$ 용량의 새로운 맥즙을 체가하고 5일동안 더 발효한 맥주가 미각검사에 합격되므로써 종내외 9일간 발효에 비하여 각각 22%내지 28%의 방율증가가 可能하게 되었다.

Traditional medicines (TM) in Korea, China, and Japan share most of the theories and therapeutic tools, but there are also differences due to their unique histories and cultures. Here, we aim to identify the differences in the utilization of TM theory between three countries by analyzing herb usage data in terms of the related traditional theories. Herb usage data of each country was collected from "Investigation of Korean medicine use and herbal medicine consumption survey" (Korea), "Analytical report on circulation of key Chinese medicinal materials" (China), and "Survey report on raw material crude drug usage" (Japan). Fifty five herbs with sixty features belonging to five theoretical categories (four properties, five tastes, targeting meridians, treatment strategies, and herbal parts) were selected and analyzed. Weight Sum Model (WSM) and Network-Based Group Features (NBGF) were used to compare the theoretical characteristics of TM between three countries. For the statistical evaluation, we developed and applied Herb Set Enrichment Analysis (HSEA) for WSM and NBGF results. HSEA for WSM results revealed the kidney meridian were targeted more in Korea than Japan, while the spleen meridian were targeted more in Japan than Korea. Herbs with sour taste were used more in Japan than China. HSEA for NBGF results found that NBGF including warm, neutral, sweet, and tonifying features were more dominant in Korea and than Japan, while NBGF including cold, bitter, heat-clearing features were more dominant in Japan than the others. These results suggest that TM in Korea, China, and Japan have unique aspects of practice patterns and theoretical utilization.
