This study aims to examine the extent of lifestyle behavior changes, perceived restrictions in daily life, and their relationship during the COVID-19 pandemic. Using the 2020 Community Health Survey data, this study calculated perceived restrictions in daily life among adults in Korea during the pandemic by sociodemographic characteristics and lifestyle behavior category (physical activity, sleeping duration, drinking, smoking, social contact, public transport use, food delivery, instant food consumption). The generalized linear model examined the relationship between behavior change and perceived restriction on daily life. A total of 227,808 respondents were analyzed. 56.70% of the population perceived their daily lives restricted by 50% and more during the pandemic. The majority of the population decreased physical activity, social contact, and public transport use (52.71%, 89.70%, and 63.74%, respectively). Individuals who decreased physical activity, sleep duration, and social contact frequency, and those who increased drinking frequency, food delivery, and instant food consumption perceived greater restrictions in daily life than those who did not change respective behaviors (p<0.001). In conclusion, decreases in social contact and physical activity and increases in use of food delivery and instant food consumption were associated with greater perceived restrictions of daily life during the pandemic. Efforts to alleviate the negative impact of the pandemic on psychological well-being may need to involve attempts to improve healthy life behaviors.

In this paper we collect data concerning sleep environments in a bedroom and analyze the relationship between the collected condition data and sleep. In addition, this paper detects scene changes from the subjects in a sleeping state and presents the physical conditions, reactions during sleep, and physical sensations and stimuli. To detect scene changes in image sequences, we used color histogram for the difference between the preceding frame and the current frame. In addition, to extract the tossing and turning for different situations, the subjects were instructed to enter the level of fatigue, the level of drinking, and the level of stomach emptiness. For the sleep experiment system, we used the H-MOTE2420 Sensor composed of temperature, humidity, and light sensors. This paper is intended to provide the best sleep environment that enhances sleep quality, thus inducing people today to get regular and comfortable sleep.

This study was attempted to understand the effect of the violence victim experience of Korean adolescents on smoking using the data of the 15th (2019) online youth health behavior survey. The subjects of this study were 57,303 people, and the data were analyzed using the SPSS / Win 26.0 program for frequency analysis of complex samples, cross sample analysis (Rao-Scott ��2 test), and logistic regression analysis of complex samples. The main result was 12.7% of the smoking subjects. Those who smoked were significantly more 9.6% and 22.0%, respectively, compared to those who had no more than 1 or 2 times of violence. Smoking of Korean adolescents adjusted for gender, grade, academic record, economic status, drinking, family living, and usual stress increased the odds ratio for smoking by 1.66 times when the degree of violence damage experience increased by 1 unit. As a result of the above, as the degree of violence victimization of adolescents increases, the likelihood of smoking increases. Therefore, it is necessary to multidisciplinary convergence effort to the prevention and management of violence of adolescents, and to reduce the smoking of adolescents.

It was found that the level of alcohol concentration in both mouse and human sera can be significantly decreased up to 42% by oral administration of the mixtures of the extracts of Hovenia dulcis THUNB and Alnus japonica Steud. A single treatment of extract from Hovenia dulcis reduced the serum alcohol concentration to 32%, compared to 13% in treating the extract of Alnus japonica. Similar patterns were observed in enhancing alcohol dehydrogenase (ADH) and glutathion-S-transferase (GST) activity in the liver. The inhibition of cathepsin activity was also greatly reduced by administrating the mixture of both extracts : however, the extract of Alnus japonica did not affect the acitivity of cathepsin. It was concluded that the mixture of both extracts had synergic effect on reducing serum alcohol concentration and improving the detoxification process due to alcohol administration in the liver.

To find the influence of family support degree on the depression of the elderly in a rural area, a questionnaire survey was made toward 163 persons who were more than 65 years old and living in a township at Chollanamdo province from January 1st to February 20th, 1998. The major findings are as follows : 1. By simple analysis significantly associated variables with depression score were residence, adequacy of pocket money, health consciousness, drinking alcohol, smoking, score of activity of daily living(ADL), score of instrumental activities of daily living(IADL), and degree of family support among female respondents(p<0.05). 2. To find the influence of family support on the depression score excluding other associated variables, multiple regression analysis was made and it was found that family support was associated significantly with affective, somatic, psychomotor and psychological domain of depression score among male, and somatic, psychomotor and psychological domain among female(p<0.05). The above finding suggest that family support degree is an important factor to be associated with the depression of the elderly in the rural area. So to deal with the depression of rural elderly, how to make close relation among family members must be considered.

Climatological characteristics in the variation of soil temperatures in Korea were investigated using Korea Meterological Administration's observation data. And the impacts of soil moisture on the variation of soil temperature were examined using observed precipitation data. The climatological averages of soil temperatures are ranged from 14.4 to $15.0^{\circ}C$ regardless of depths. And they showed an latitudinal gradient with a warm temperature at the southern region and 'U' shape as in the air temperature with a high value along the coastal region. The relatively higher heat capacity and low conductivity of soil compared to those of the air resulted in the significant delay of the maximum and minimum date with depth. As a results, soil acts as a heat source during winter while a heat sink during summer. Global warming and urban heat island have increased the soil temperatures with an average rate $0.3\~0.5^{\circ}C/10-year$ as in the air temperature during last 30 years $(1973\~2002)$. However, the warming rate is maximized during spring contrary to the winter in the air temperature. The temporal variation of soil temperatures is strongly affected by that of soil moisture through an modification of the heat capacity and heat convection. In general, the increased soil moisture clearly decreased the temporal variations and increased the deep layer soil temperatures during cold season.
