취반용 보리 종실 내 (1-3, 1-4)-$\beta$-glucan의 축적기작을 알아보기 위하여 개화 후 일정 간격으로 보리 종실을 채취하여 (1-3, 1-4)-$\beta$-glucan 함량, (1-3, 1-4)-$\beta$-glucanase 활성 및 전분함량과 $\alpha$-amylase 활성을 조사하였다. $\beta$-glucan 함량은 등숙 초기에 매우 낮았으나 개화 후 15~25일 사이에 급속히 증가하였고 개화 후 30일경에는 종실 건물중의 3.5~4%로 증가하였다. (1-3, 1-4)-$\beta$-glucanase 활성은 등숙 초기에 높았으며 등숙이 진전될수록 감소하였다. $\beta$-glucan 함량과 (1-3, 1-4)-$\beta$-glucanase 활성간에는 고도로 유의한 부의 상관관계가 인정되었으나 등숙 종실 중의(1-3, 1-4)-$\beta$-glucanase 활성이 매우 낮은 수준이므로 $\beta$-glucan 축적량에 크게 영향을 미치지 않을 것으로 추정되었다. 전분함량은 등숙이 진전됨에 따라 지속적으로 증가하였으며 개화 후 10~20일에 가장 뚜렷하게 증가하였다. 포도당함량은 등숙이 진전됨에 따라 현저히 감소하였으며, 등숙 초기와 중기에 감소 정도가 매우 컸다. $\alpha$-amylase의 활성도 등숙이 진전됨에 따라 현저히 감소하였으며, 감소 정도는 등숙 초기와 중기에 매우 컸다.

Determination of weekly and daily energy expenditure was made on 62 Republic of Korea Army cadets who were selected at random in order to estimate the weekly and daily ealorie expenditure. Basal metabolic rate (B.M.R.), and energy cost of various military and daily activities were measured by indirect calorimetry using open circuit method. Time-motion studies were also carried on using a stop-watch. The total weekly energy expenditure was calculated by summation of data using energy cost per minute, and the time spent on each activity. Determination of daily energy expenditure was deduced from each data of weekly energy expenditure. Food survey was also carried on for a week, and daily calorie intake was determined by a weekly average discounting loss in cooking. All measurements were determined from the Standard Table of Food Composition published by the Ministry of National Defense (1961). Following data were observed. 1. Physical status of cadets are as follows. Please note that the height and weight averages are 1-2cm and 4-5kg respectively over that of the Seoul National University students. First year Height 167.92 cm $(S.D.{\pm}4.09)$ Weight 61.72 kg $(S.D.{\pm}4.53)$ Second year Height 167.89 cm $(S.D.{\pm}3.46)$ Weight 63.01 kg $(S.D.{\pm}4.61)$ Third year Height 168.15 cm $(S.D.{\pm}4.24)$ Weight 43.48 kg $(S.D.{\pm}5.03)$ Fourth year Height 168.10 cm $(S.D.{\pm}3.70)$ Weight 64.02kg $(S.D.{\pm}5.10)$ 2. The B.M.R. of cadets averaged $36.57\;Cal./m^2/hr.(S.D.{\pm}3.63\;Cal./m^2/hr.)$ is almost equal with data on the same ages of civilians and the Japanese, but a lower average of $5.1\;Cal./m^2/hr.$ than that of a common soldier. 3. The energy expenditure during various military activities is close agreement with Consolazio. Passmore and Durnin, and Japanese reports.

This study was conducted to improve the antioxidative activity of instant noodles containing enzymatic extracts from Ecklonia cava (EEC). EEC has relatively better antioxidative activity than extracts from other indigenous plants in Jeju Island. The EEC (2.5 mg/mL) had 82.5% for the hydroxy radical, 78.4% for the DPPH radical, and 64.9% for the superoxide anion radical scavenging activities, and 65.2% for the cell viability (100 ${\mu}g/mL$). According to the texture of the dough, the DPPH free radical scavenging of uncooked instant noodles, sensory evaluation of cooked instant noodles, and turbidity of the cooking drip, the optimal EEC concentration was 1.8% for the instant noodles. The major amino acids in the instant noodles with EEC were glutamic acid (24.2%), proline (10.2%), valine (10.0%), and isoleucine (12.3%). The zinc and iron in the instant noodles were enhanced by adding 1.5-1.8% EEC. The antioxidant activity of instant noodles with EEC was 75.4% for the hydroxy radical, 74.1% for the DPPH radical, and 51.2 % for the superoxide anion radical scavenging activities.

For identifying the cause of the difference from the texture of mealy potatoes-Namjak and soomi- and soggy Potatoes-Daeji and Dowon-, starch and pectic substances and their relating materials were analyzed, and polygalacturonase(PG) activity was measured. The shape and size of Namjak and soomi starch granules were circular and diameter ranged from 0.02 to 0.024 mm. In the meanwhile, Daeji and Dowon had two sizes of starch granules; larger one tend to be oval in shape and diameter of longer side ranged from 0.04 to 0.045 mm, that of narrower side ranged from 0.02 to 0.03 mm and smaller one was rather circular in shape and average deameter was below 0.005 mm. Oval shaped potato starch grancules under polarized light showed dark cross of V-shape, whereas circular granules showed cross shape. Total sharch contents of Namjak and soomi were higher than that of Daeji and Dowon. The changes of pectic substances were the decrease of the insoluble pectin and the increase of the soluble pectin, and the reduction of the total pectic substance content after cooking. This phenomena were more prominent in Namjak and Soomi than in Daeji and Sowon. PG activities of Namjak and Soomi were greater than Daeji and Dowon. Calcium contents of Namjak and Soomi were lower than Daeji and Dowon. Phytic acid contents of Namjak, Soomi, Daeji and Dowon were 0.093%, 0.096%, 0.078%, and 0.081%, respectively. Hardness of Namjak and Soomi were less than Daeji and Dowon. The mealy potatoes had higher starch contents, higher tendency to pectin solubilization, higher PG activities, lower calcium contents and less hardness than the soggy Potatoes.

BACKGROUND/OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has affected the entire world population in many ways. This study aimed to analyze the patterns of changes in eating, food purchasing and preparation, physical activity, and subjective health after COVID-19 outbreak by various sociodemographic factors and to understand the factors associated with changes in subjective health. SUBJECTS/METHODS: A cross-sectional survey using a representative sample from Seoul was used for the analysis. The data collection was conducted from September to October 2020. A total of 3,833 citizens aged more than 18 years old participated in the Seoul Food Survey. Descriptive statistics and generalized ordinal logistic regression models were used to understand the changes in health behaviors, health indicators, and subjective general health by various socioeconomic status. RESULTS: It was shown that the changes in household income, food expenditure, food consumption and physical activities differed significantly by age, education, occupation, income, weight, and food security status. Low-income and food-insecure households were affected more severely by the pandemic. Older age, household food insecurity, income reduction, increased home cooking and frequency of having instant foods, decreased physical activity and weight gain were significant factors explaining worse perceived health during the COVID-19 pandemic. CONCLUSIONS: The results suggest that focusing on older populations and low-income families with food insecurity should be prioritized during infectious disease outbreaks. In addition, the role of physical activities and instant food consumption in explaining perceived health should be investigated further in this prolonged battle with the pandemic situation.
