Changes in chemical composition of the ethanolic extract of roasted Asparagi Tuber were investigated by HPLC. One dramatically increased peak $(t_R\;14.85 min)$ was isolated by silica gel column chromatograph and identified as 5-hydroxymethyl furfural (HMF) by comparing its $1^H-NMR$ data with that of a commercial standard. HMF content reached its maximum level at $190^{\circ}C$ for 60 minutes. Under these conditions, HMF contents in the roasted Asparagi Tuber was increased about thirteen times (9.26mg/g) over the not-roasted control (0.71 mg/g). No significant differences were found in macrophage-activating, prolyl endopeptidase-inhibiting, antioxidative (DPPH), anti-coagulating (activated partial thromboplastin times), and ACE-inhibiting activities between roasted and not-roasted Asparagi Tuber.

The purpose of this study is to understand the changes in the daily life and quality of life of the elderly due to the spread of COVID-19. This study attempted to supplement the limitations of quantitative analysis by performing both quantitative and qualitative analysis. A large-scale representative data, the Elderly Survey 2017 and 2020, were analyzed, and in-depth interviews were conducted with a total of 16 elderly people in Gwangju and Seoul. As a result, it was found that the overall quality of life was positively changed compared to before Corona. The frequency of contact and visits with family members decreased whereas the time spent watching TV increased. The elderly's adaptation to daily life has a series of processes since the first outbreak of COVID-19. At the beginning of the outbreak, there were fear, anxiety, and depression due to isolation, but gradually made efforts to adapt to the new situation. They reported that they realized the importance of human relationships, especially spouses, in a crisis situation and that there were some positive aspects as well. Finally, in all these results a difference was found between single-person households and multi-person households. Through the above research results, academic and policy measures were discussed.

우리나라에서는 지난 40여 년 동안 경제의 외형적 성장을 통한 물질적인 풍요에 많은 관심을 기울여왔다. 이러는 과정에서 가족형태의 변화, 소득증가, 평균수명증가, 주5일 근무도입, 환경파괴로 인한 건강과 생명위협 등 생활환경의 변화가 발생하여 사람들은 건강하게 오래 살고자 하는 생활모습으로 변모해가고 있는 실정이다. 즉, 근년에 들어 국민소득 $20,000의 시대를 향하면서 가정경제생활의 안정을 이루자 삶의 질적 수준향상을 추구하는 경향이 사회 전반적으로 퍼져나가고 있다. 이런 경향은 서구의 생활모습의 영향을 받아 웰빙문화로 나타나고 있다. 웰빙이란 자신과 가족의 건전하고 건강한 삶을 위해 지향하는 의식주 전반에 관련되는 합리적인 소비문화과정이라고 정의할 수 있다. 다시 말해서 Well-Being은 경제력으로 단순히 잘 먹고 잘 사는 인생을 뜻하는 것이 아닌, 정신적으로 풍요롭고 육체적으로 건전한 문화적인 삶으로 이해해야 한다. 따라서 본 논문은 21세기에 들어서 우리나라에서 생활환경의 변화에 따른 새로운 생활모습으로 떠오르는 웰빙문화의 탄생배경, 웰빙현상이 지니고 있는 모호하고 다중적인 모습을 관련 문헌을 통하여 웰빙개념을 보다 구체적으로 올바르게 정리하여, 향후 기업경영에 활용할 수 있는 시사점을 제시하고자 한다.

Purpose - This study investigated small business members' cognition of happiness in accordance with changes of employment environment at the nation's industrialization. The study verified effects of labor workers' psychological wellbeing conditions upon life satisfaction as well as the effects of job burden and family burden of employment instability. Research design, data, and methodology - The subjects were small business workers in Seoul and Metropolitan areas. The author collected 150 copies of effective questionnaires. Regression analysis, hierarchical analysis and 3-stage mediation regression analysis were done. Results - The findings of this research was that psychological wellbeing factors alleviated job burden and family burden to increase satisfaction with life. Employment instability moderated between job burden and satisfaction with life, job burden between environmental control and satisfaction with life, and family burden between goal and satisfaction of life. Members needed sub factors of psychological wellbeing, especially reflection for self-acceptance. Conclusions - This study inspected effects of small business workers' psychological wellbeing upon life satisfaction at changes of management environment as well as labor environment to verify effects of job burden, family burden and employment instability and to find out conditions of human resources management from point of view of small business and workers.

Deproteinization has been recognized as a prerequisite for amino acid analysis of plasma samples. For plasma stored at room temperature, delaying deproteinization for 30, 60 or 120 minutes did not result in significant changes in the mean CV (coefficient of variation), which ranged from 4.4 to 5.6%. However the mean CV of aspartic acid, ${\alpha}$-aminoadipic acid, alanine and lysine was about 10%. When the plasma was stored frozen at -20${^{\circ}C}$, the CV was increased at 0 and 120 minutes after thawing, to 12.4% (range, 4.1 to 35.3%) and 8.0% (2.5 to 30.7%), respectively. The concentrations in plasma during storage at room temperature of all the amino acids analyzed showed significant changes. In plasma stored for 30 minutes at room temperature, 17 amino acids increased in concentrations and two decreased. Extending this period to 60 or 120 minutes increased the instability as compare to the reference group. Storing plasma at -20${^{\circ}C}$ for 2 weeks resulted in significantly greater changes in the amino acid concentrations than at room temperature. On extending the storage time at room temperature, after thawing, to 30, 60, and 120 minutes, 21, 20, and all 22 amino acids respectively changed significantly (p<0.01). The present study indicates that methodological errors occur in the concentrations determined for all amino acids when plasma is left at room temperature. The storage of frozen non-deproteinized plasma accompanied more significant changes in most amino acid concentrations and thus should be avoided. Deproteinization should be performed as soon as possible after plasma collection.

In present-day Korea, a climatic change is causing various changes to the life of people and their body. The climate is more and more warm, so the internal environment of people's body is exchanging to warm. The climatic change's range is big and the speed is fast. So the harmony of human body is being destroyed and the human body's adaptation ability is becoming low. At this condition, diseases more frequently occur. So doctor must expect the occur of diseases and practice early treatment. And in present-day Korea, a life environmental change is being advanced. The life environmental change is causing big changes to the people's body and having influences to the occur of diseases. To this problem, doctor must expect and practice early treatment. This thesis would like to interpret about present-day Korea's climatic changes and life environmental changes in Korean Medicine point of view, and try to present the method of Korean Medicine early treatment. And comment on present-day Korea's early treatment method especially on health supplement or functional food and vaccination.

The meaning and context of objects has been changed in various ways depending on the times. Functionality of objects has been developed in various directions according to the point of view of the objects. Objects have been used as mediums to realize art in daily life, and to realize the relational forms. Based on this, it is confirmed that furniture can be an appropriate medium to articulate everyday life and to derive relational form. The 'furniture as a behavior' has the following characteristics. First, it functions to make daily life unfamiliar. By doing something unfamiliar in everyday life, users experience similar experiences as when they entered the surreal world of art museum. In this way, the possibility of everyday arts is acquired. Second, the mental and behavioral functions of furniture are continuously changed by interaction with the user. Behavior does not occur unconsciously, but involves changes in consciousness that the user intentionally does. Therefore, as the user's level of consciousness grows, personal experience changes, and the behavioral function of the household changes. The study of 'furniture as a behavior' is suggested as one approach to design furniture.

Drug addiction is a severe psychiatric disorder characterized by the compulsive pursuit of drugs of abuse despite potential adverse consequences. Although several decades of studies have revealed that psychostimulant use can result in extensive alterations of neural circuits and physiology, no effective therapeutic strategies or medicines for drug addiction currently exist. Changes in neuronal connectivity and regulation occurring after repeated drug exposure contribute to addiction-like behaviors in animal models. Among the involved brain areas, including those of the reward system, the striatum is the major area of convergence for glutamate, GABA, and dopamine transmission, and this brain region potentially determines stereotyped behaviors. Although the physiological consequences of striatal neurons after drug exposure have been relatively well documented, it remains to be clarified how changes in striatal connectivity underlie and modulate the expression of addiction-like behaviors. Understanding how striatal circuits contribute to addiction-like behaviors may lead to the development of strategies that successfully attenuate drug-induced behavioral changes. In this review, we summarize the results of recent studies that have examined striatal circuitry and pathway-specific alterations leading to addiction-like behaviors to provide an updated framework for future investigations.

Purpose : This study aimed at uncovering the disabled adult's way of thinking and behavior due to their changed life style. Method : In depth interviews with 11 participants were held and analysed based on the Grounded Theory Methodology by Strauss and Corbin (1990). Result : This study showed us that the disabled are getting independent by selfconfidence through developing coping strategies for their physical, emotional, social, sexual problems. And in the process of creating these strategies, support structures, satisfaction for performance effect, financial burdens, and mobility had an effect on the intervening factors. Adults who become disabled go through many changes. First, they have vague hopes of improving. Second, they become discouraged. Third, they accept their disability. Next, they learn coping strategies and finally, they integrate the changes into their new life style. Conclusion : This study can be utilized in rehabilitation nursing so that the disabled can adapt to their changed life style quickly and lead independent and self-confident lives.
