  • 본 연구는 불안 및 정상그룹을 대상으로 서열성을 판단하는 인지과제 수행과정에서, 유발된 배경정서와 내재된 불안 수준이 과제처리에 미치는 영향을 밝히고자 하였다. 어휘 간 관계정보 중 서열판단 과제에서의 피험자 내 변인으로 유발정서 유형(기쁨, 분노, 슬픔 및 통제) 및 인지과제 처리유형(숫자서열 및 크기서열)을, 피험자 간 변인으로는 일반 대학생 중 벡 불안척도 검사를 통해 분리된 불안여부로 설정한 후 반응시간 및 오류율의 차이를 분석하였다. 자극의 제시와 반응의 수집은 DmDx5를 활용하였다. 실험결과, 집단 간 반응의 차이가 확인되었고 불안그룹이 과제유형에 관계없이 모든 정서유발 조건에서 정상그룹에 비해 더 느린 반응시간과 더 높은 오류율을 보였다. 그리고 정서유형에 관계없이 두 서열과제에서도 지체응답 경향을 보였다. 다음으로 정서유발 및 서열과제 효과를 통해 정서 및 과제 특정적인 반응경향을 확인하였는데, 슬픔조건이 타 정서보다 빠른 반응을 보였으며, 숫자서열 조건이 크기서열 조건보다 더 빨랐다. 이는 그룹별 그리고 과제유형별 인지과제 처리경향은 물론, 수반되는 정서유형에 따른 응답경향의 차이를 확인해 줌으로써 정서-인지 관련 행동에서의 기저의 배경정서가 처리과정에 주요 요인이 될 수 있음을 시사하는 결과라 하겠다.

  • Gordon Cullen, who tried to understand urban landscapes in terms of visual attention, introduced a concept called 'Space and Infinity' in his book 'Townscape'. According to him, urban images like infinity spreading across the sky are more effectively created when we happen to see an open space while walking along a ground-level street than when we look at the sky. This study aims to quantitatively examine if urban observers pay more attention to spaces like pilotis on the bottom of a building. Thus, this study collected observers on actual urban landscape images and partially-edited images and conducted an experiment by adopting Eye-movement Tracking to find out if they actually pay more visual attention to a space like pilotis. This study selected a total of 50 people as research subjects and divided them into two groups. Image 1 was shown to one group, and Image 2 with the pilotis space edited was shown to the other group. As an experiment to find objective evidences on Gordon Cullen's 'Space and Infinity', this study analyzed difference between Image 1 and Image 2, and it was found that the domain of pilotis showed a value five times higher than the average visual attention since it attracted much visual attention although it was very small in area. That is, it has objectively clarified that people get most fascinated with a place with infinite images in the background like a pilotis space out of all the urban landscapes as Gordon Cullen's theory. In addition, the differences in visual concentration of pilotis space by sex, by subject was examined, and there was no significant difference in visual concentration of pilotis space by gender. As a result of examining the difference of visual concentration by classifying the subjects into architectural related major, the major group showed higher frequency of viewing than the non - major group.

  • This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the 'Healthy pattern', 'Processed meat pattern', and the 'Alcohol pattern'. The 'Healthy pattern' was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The 'Processed meat pattern' was characterized by high consumption of processed meats and instant foods. The 'Alcohol pattern' was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the 'Processed meat' and 'Alcohol' patterns had significantly higher scores on subjective stress perception compared to people following the 'Healthy pattern'. To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the 'processed meat' and 'alcohol' dietary patterns.

  • The purpose of this study was to obtain information from married women regarding obesity-related factors and psychological eating behaviors, and to compare those variables among three groups, namely underweight, normal, and obese. The participants completed questionnaires regarding general obesity-related factors, major food servings/day, physical activity, dieting behaviors, perceptions of body image, and psychological eating behaviors. The results were as follows: The obese women reported a higher percentage of family history of obesity (74.8%) than the normal (43.5%) or underweight (28.2%) women. Most of the obese women (90.0%) accurately perceived their body image compared to 72.5% of the underweight and 56.6% of the normal weight women(p<0.001). No significant differences were found among the three groups for daily hours of exercise or computer use. In the case of hours of television watched daily, significant differences were found among the groups (obese 104 min/day, normal 87 min/day, underweight 76/min, p<0.05). Only 17.9% of the obese women reported eating 2 servings of milk products/day and only 23.2% of them reported eating 3 servings of protein foods/day as compared to the normal (25.4%, 18.0%) and underweight (29.4%, 41.7%) (p<0.01) women. About 98% of the obese and 78.5% of the normal weight women wanted to loose weight compared to only 10% of the underweight women (p<0.001). Psychological eating behavior was significantly correlated with subject BMI ($r^2$=0.32, p<0.01). Also, more obese women were unsatisfied with their body and had emotional eating behaviors as compared to the normal and underweight women, and this was statistically significant (p<0.001). In conclusion, the obese women had high perception rates of their body image, but had negative-psychological eating behaviors. Special behavior therapy is needed for obese women who show body dissatisfaction, emotional eating behaviors, long hours of daily TV viewing, and low intakes of protein and milk products.

  • This study was conducted to study the relationship between food intakes, glycemic index (GI), glycemic load (GL), and body weight with high school boys residing in Seoul. The subjects of 329 boys were divided into normal weight group (BMI < $23\;kg/m^2$, n = 212) and overweight group (BMI ${\geq}\;23\;kg/m^2$, n = 117) by body mass index (BMI). The food intakes data obtained by the 3-day food record were analyzed by Can pro 3.0 software. Anthropometric measurements and physical activities were collected from each subject. Daily dietary glycemic index (DGI) and dietary glycemic load (DGL) were calculated from the 3-day food record. Body weights and BMI of normal weight group were 58.8 kg and $19.9\;kg/m^2$ and those of overweight group were 79.2 kg and $26.8\;kg/m^2$, which were significantly different between two groups (p < 0.05). Total food and animal food intakes of normal weight group were significantly higher than overweight group (p < 0.05), and vegetable food and other food intakes of normal weight group showed higher than overweight group. All nutrient intakes of normal weight group were higher than overweight group. Dietary fiber, calcium, potassium and folate intakes of normal weight group and overweight group were under 65% of the dietary reference intakes (DRIs). Major food sources of energy intake for both groups were rice, pork and instant noodle in order. Mean adequacy ratio (MAR), an index of overall dietary quality were 0.83 in normal weight group and 0.79 in overweight group, which showed significantly higher in normal weight group than overweight group (p < 0.05). Mean daily dietary GI of normal weight group and overweight group were 67.7 and 68.2, respectively. Mean daily dietary GL of normal weight group and overweight group were 214.6 and 202.7, respectively, and which was significantly different between the two groups (p < 0.05). Major food sources contributed to DGI and DGL were rice ($\geq$ 55%) in both groups. DGI and DGL were not significantly correlated with anthropometric data. Activity adjusted to energy intake was negatively correlated with percentage of body fat (r = -0.1308, p < 0.01) and that was positively correlated with height (r = 0.1227, p < 0.05) and lean body mass (r = 0.1351, p < 0.05).

  • This study investigated the influence of the application of the career education programs related to the science of the elementary school on the career choice. For this study, a total of 32 lessons (4 units) utilizing the career education programs related the science curriculum were developed. The study subjects were 128 students from Y elementary school located in Incheon. A test with regard to the science related career choice and the science related career choice factors was performed before and after the lessons. For more detailed analysis, the experimental group was divided into two groups of female and male students; students who hope and do not hope career in science-related fields. As a result of the performance of career education programs, it showed a significant improvement in the 'science related career choice'. And, it also showed all significant improvements in 'science related major/department, education lecture selection'. It was possible to know that the students who do not wish science related jobs in the future also changed their mind on to the science. In addition, all the subcategories of the 'preference for science learning' area such as 'preference for science subject', 'preference for experiment', 'recognition of science subject availability', 'recognition of the impact of teacher' showed a significant improvement. The 'perception about career related to science' showed a significant improvement on the whole. There was no significant improvement on the whole in 'participation in science related activities'.

  • Even though alcoholism is a multi-factorial psychiatric disorder, it is reasonable to suppose that genetic factors play a substantial role in the manifestation of this disorder. Because alcohol is the reinforcing substance which manifests its effects through activation of the mesolimbic dopaminergic reward pathway of the brain, the gene encoding dopamine receptor subtypes can be a major natural candidate gene. Since 1990, many association studies have identified strong evidence implicating the dopamine D2 receptor(DRD2) gene in alcoholism, specifically TaqI A minor(A1) allele. Association studies have also been conducted on other dopamine receptor(DRD3 & DRD4) polymorphisms but the results have yet to be confirmed. Through a number of other approaches, each dopamine receptor gene has been investigated in association with different phenotypes in alcoholism, but further researches will be needed. In conclusion, studies in the past decade have shown that the TaqI A1 allele of the DRD2 gene is associated with alcoholism in various subject groups. Other dopamine receptor genes have since been added to the list but yet to be identified. Thus, the knowledge of these genes and their functional significance will enhance the understanding of the underlying biological mechanisms of alcoholism. Furthermore, it could lead to more helpful prevention and treatment approaches to alcoholism.
