최근 대두섭취가 극히 제한되어 있는 서구사회에서 전립선암, 유방암, 골다공증과 같은 호르몬 관련 질환과 심혈관질환의 유병률이 대두식문화권 있는 아시아인에 비해 현저히 높음이 몇몇 역학연구에서 보고 되고, 대두에 함유된 이소플라본의 생리적 활성이 밝혀지면서 대두 및 이소플라본 섭취에 대한 관심이 세계적으로 높아지고 있다. 그러나 한국인의 이소플라본 섭취 수준에 관한 자료는 극히 제한되어 있다. 이에 본 연구에서는 한국인의 이소플라본 섭취 수준을 평가하고 생태학적 변인에 따른 대두/이소플라본의 섭취 수준의 차이를 비교 분석하고자 하였다.(중략)

Objectives: This study examined the effect of mood and personality characteristics on psychophysiological responses measured by a biofeedback system in a normal population. Methods: Fifty healthy volunteers without any history of medical or psychiatric illnesses participated in this study. We measured the Spielberger trait anxiety inventory, Beck depression inventory, and Eysenck personality questionnaires in these subjects. Using the J & J biofeedback system, we also measured skin temperature, electrodermal response, forearm and frontal electromyography (EMG)s in 3 experimental conditions of baseline, stress, and recovery phases. Results: Trait anxiety did not show any significant correlation with psychophysiological responses except stress response in forearm EMG levels(r=0.282, p<0.05). Depressed mood was negatively correlated with forearm EMG levels in baseline (r=-0.299, p<0.05) and recovery phases(r=-0.314, p<0.05). Subjects with relatively high levels of depressed mood showed different stress and recovery responses in frontal EMG levels compared with those with relatively low levels of depressed mood (F=4.26, p<0.05). Extroverted subjects showed higher levels of forearm EMG than introverted ones in stress phase. Conclusion: Mood and personality characteristics in healthy subjects are closely related with psychophysiological responses measured by a biofeedback system. We suggest that mood and personality characteristics should be considered as important variables in analyzing abnormal psychophysiological responses in some psychiatric patients.

동일한 감성자극을 받더라도 개인의 대뇌변연계에 저장된 정보에 의하여 그 느끼는 감성이 달라진다. 대뇌변연계에 저장되는 정보에 영향을 주는 요소로서 전전두엽의 비대칭성, 성별, 연령, 문화, 교육, 환경(지역 및 사회적) 등이 있다. 예를 들면 동일한 음질을 갖는 소리에 대하여 청취하는 사람에 따라 서로 다른 음향감성을 느끼게 되며 동일한 색채에 대하여는 풍토색이 서로 다른 환경에서 성장할 경우 그 느끼는 색채감성이 달라지게 된다. 이와 같이 감성에 영향을 주는 여러 요인들과 그 결과와의 상관성을 도출하여 궁극적으로 감성적 생리/병리에 활용하기 위해 산업자원부 지정 심뇌혈관데이터센터에서는 향후 감성에 영향을 줄 수 있는 다양한 생리신호와 그 결과로서의 감성을 체계적으로 데이터베이스화 해나갈 계획이다.

This study aimed to identify the correlation between internal/external motive, academic failure (emotion, behavior, task preference), depression (depressive emotion, behavioral disorder, loss of interest, self-degradation and physiological symptom), and academic efficacy of elementary school students with underachievement basic learning, and discover the influential variables on internal/external motive, targeting 56 elementary school students with underachievement in third and fifth grade of 10 elementary schools in G metropolitan city. The research conducted T-test to figure out the difference between the children with underachievement by year and carried out theregression analysis to identify the predictors of self-determination motives. First, there was a difference between the third and fifth graders in terms of the external motives. Second, the influential variables for external motives of children with underachievement included depressive emotion, loss of interest and physiological symptom. Therefore, as more third graders with underachievement study under the external motives compared to the fifth graders, it is concluded necessary to adopt a program to reduce the variables for depression that influence the external motives.

이미 발표한바 있는 Monascous sp.의 색소 배양액으로부터 식품응용에 적용하기 위한 기초적 자료를 얻기 위하여 조색소 분말의 생산, 물리적 성상과 생리적 성질을 검토하였다. 본 실험은 발효액으로부터 60％ alcohol과 pe-troleum ether로 추출하여 alcohol층에서 적색계, petroleum ether층에서 황색계 색소를 얻었으며, 생산된 적색계 조색소는 5종의 색소물질이 복합되어 있었고 pH 3에서 9까지 안정하였으며 O.D 495∼500nm에서 흡수극대를 나타내었다. 적색 조색소분말(색소 1000mcg/mg 기준 때)과 색소액은 시험 시료농도에서 bio-activity는 없었으며 급성 독소시험은 positive 용혈반응 negative였다.

Before examining stress and physiological variables (immunity, inflammation), this study conducted a pilot test to provide basic data by analyzing depression and anxiety symptoms by age group for stress coping and coping methods. As a non-face-to-face method, BDI and STAI by age group (20s to 70s) and face-to-face survey were conducted concurrently and as follow-up surveys. In 20s to 60s, according to the coping method, there was a significant decrease after stress relief, and in all age groups, anxiety decreased significantly after stress relief, and in the 50s, stress coping with exercise was the lowest after stress relief. Based on the results of this study, through basic research according to psychological variables, physiological variables according to actual stress coping methods were further verified, and subjects with high stress levels were treated with long-term exercise therapy for depression and anxiety symptoms by exercise therapy. It will be necessary to additionally verify the appropriate stress coping method for each age group and subject, such as the correlation between improvement and immunity and inflammatory response.

The purpose of this study was to explore convergence on the theory of unpleasant symptom, and factors affecting quality of life of liver cirrhosis patients. A total of 198 liver cirrhosis patients were recruited symptom experiences, physiologic factors, psychological factors, situational factors, and quality of life. Data were collected from March, to May, 2014 and analyzed using one-way ANOVA, Pearson correlations, multiple regressions analysis with PASW (SPSS) 21.0. Variables such as duration of liver cirrhosis(${\beta}=.19$, p<.001), symptom experiences(${\beta}=.19$, p=.032), physical(${\beta}=.15$, p=.008), psychological(${\beta}=.39$, p<.001) and situational factors(${\beta}=.32$, p<.001) explained 51.8% of variance in quality of life(F=15.57, p<.001). The symptom experiences, physiological, psychological and situational factors should be considered for caring liver cirrhosis patients. Symptoms of postmyocardial infarction (post-MI) patients at risk for progression to heart.

The purpose of this study is to investigate the relationship between smoking attitudes and psychophysiological variables and to find out whether smoking cessation activities can be helpful for smoking cessation. We set up Negative Attitudes experience as a dependent variable. Several factors including Psychological Resistance, Psychological Distress and brainwave(Left brain ${\theta}$, Right Brain ${\theta}$) as a physiological indicator, which was expected to affect flow, were set up as independent variables to perform regression analysis. As a result, psychological resistance had negative influences on negative attitudes toward smoking in smoking simulation game and psychological distress had positive effect. And left brain ${\theta}$ had negative influences on negative attitudes toward smoking in smoking simulation game and right brain ${\theta}$ had positive effect.

The current study investigated whether individual variation in motivational activation would predict the drug-use and interacts with discrete emotions to influence the responses to anti-drug advertisements. Motivational activation tendency indicates an individual's level to approach life-sustaining elements and defend life-threatening stimuli. Discrete emotion represents joy, sadness, and fear elicited by the advertisements. The experiment proceeded using both self-reports and physiological responses with 80 subjects. Results showed that approach motivation activation can be a target for anti-drug advertisements and in order to target individuals higher in approach activation, it is necessary to use the appeal type to elicit positive emotions such as joy.
