  • Background: The purpose of this study was to investigate the difference of height cognition ability according to dominant or non-dominant eye. Methods: Forty one healthy adults (male: 19, female: 22, 22-43 years) participated in this study. Hole in the card test was performed to identify dominant eye. To figure out height cognition ability between dominant and non-dominant eye, we had subjects answer which point is higher or even on the monitor. Results: The Right answer on dominant eye was $8.15{\pm}1.44$ point and the right answer on non-dominant eye was $7.56{\pm}1.55$ point. There was a statistically significant difference between dominant eye group and non-dominant eye group (p<.05). Conclusion: We think that the dominant eye may be used for reliable diagnosis. In future study, investigate on relation between dominant hand and dominant eye and the difference of dominant eye and non-dominant eye when to palpation are required.

  • This study investigated the influential range of landmarks and the relationship between landmarks and cognition factor so as to offer basic data to be used for the effective use and the management of landmarks. In this study, eighteen famous landmark in Seoul were selected and analyzed. The result of this study can be summarized as follows : 1) First, eighteen determining elements of cognition factors were selected via documents survey. Second, general cognition factors of landmarks were analysed using these elements through questionnaires to specialists. As a result of factor analysis, historic cultural factor, scale factor, visual form factor, locational factor and uniqueness factor were revealed. 2) According to revealed cognition factor, eighteen landmarks are categorized into four types using MDS method via questionnaire to resident in Seoul city. These four types of landmarks are: type I that are recognized by historic cultural factor; type II that are recognized by scale factor; type III that are recognized by uniqueness factor; and type IV that are recognized by visual form factor. 3) As the result of regression, the influential range of landmarks were revealed at about a 10km radius(type I : 12km type II : whole area of Seoul city≒15km, typeIII : 8.7km, typeIV : 8.5km). 4) As a result of analysing the correlation between the influential range and the cognition factor through multiple linear regression analysis, the locational factor is the main factor affecting the influential range of landmarks in every type. The uniqueness factor comes next, which affects influential range partially. 5) Except type 1, as a result of analysing the correlation between influential range and the physical heights of landmarks, a quadratic equation is revealed, showing that the influential range of landmarks over 200 meters in height shows a radical change. Landmarks can be used as reinforcement tools of legibility, effective tools for landscape management and for the improvement of a community's image. This study on the influential range of landmarks and main cognition factor can be utilized as a landmark management plan and in urban planning, such as a new town plan.

  • The purpose of this paper is to examine the visual evaluation structure about the formal changes of streetscape by the different moving speed in two alternative control plans for the building height and the setback regulation. The virtual reality system is applied to the experimental tool. Eighty-two experimental models are made in consideration of the height and the setback of the building regulation cased by Midou-suji street in Osaka City, Japan. and ten typical models are selected by pre-experiment. Since the changes of the landscape structure consists of the height and the setback of the building, four the evaluation items are set: grade of continuity, order, openness, preference. As there are eighty-two landscape models which are too many to be applied in this experiment, ten role models are drawn out and used in this experiment. The mean difference test, discriminant analysis, and multiple linear regression methods had been used for the statistical analysis methods. The results of this study are as follows; 1) It is found out the fact of the difference evaluation structure amount experiments models. 2) From the sketch analysis and interview, it is found out difference cognition structure by the moving speed and alternatives. 3) From the discriminant and regression analysis, it is found out that the evaluation value about continuity becomes low by the moving speed change from walking speed to driving speed. We suggest that continuous experiment should be made with a variety of groups and models, and general and universal results should also be come out of the experiments above.

  • Prader-Willi syndrome (PWS) is a multisystemic complex disorder characterized by hyperphagia and impaired satiety which lead to severe and early obesity. In infancy, hypotonia and poor suck are main problems, and a child goes through Failure-to-thrive. During childhood, clinical manifestations change to food seeking as well as excessive weight gain, short stature, developmental delay, cognitive disability and behavioral problems. Also, growth hormone insufficiency is frequent. Most patients receive the recombinant growth hormone (rGH) therapy that provides improvement in growth, body composition, and physical attributes. The clinical care guideline for rGH therapy in PWS had been noticed in 2013. The rGH therapy helps in body fat, lean body mass, height SDS and head circumference. Also, the rGH therapy helps motor function, psychomotor development and cognition and behavioral issues.In Samsung medical center, there are clinical care guidelines for rGH therapy in PWS and an useful application for the patients. 'Living with PWS', the name of an moblie application for PWS patients, was introduced in the lecture. The application revised to version 2. It was made more convenient to users than in version 1. It helps caregivers to schedule the rGH therapy and to monitor height and weight.

  • 동해(東海)는 애초 방위에 따라 붙인 명칭이었지만, 오랜 세월의 역사적 연고를 온축한 고유명사이기도 하다. 동해는 자연의 지리공간인 동시에, 숱한 역사적 사연과 문화적 의미를 내포하고 있는 역사문화의 공간이기도 하다. 이 글은 동해의 역사 문화적 사연 중, 동해에 대한 선인들의 지리 인식을 검토하고, 나아가 문학작품에 그려진 여러 형상을 살펴본 것이다. 조선의 지식인들은 큰 차원에서 세계의 지리를 파악했고, 그 구도 속에서 국토의 지리와 지세를 인식했다. 이에 따르면 백두산은 천하의 조종(祖宗)이 되는 두 산 중 하나로 요동별관과 한반도와 일본의 지리를 통어한다. 고래로 역사지리가들은 백두산과 백두대간을 거론하며 동해를 짝 지워 언급하였다. 백두대간과 동해는 짝이 되면서 크기와 너비, 높이와 깊이, 그리고 위엄과 도량을 함께 갖춘 온전한 국토지리의 표상이 된다. 동해의 다채로운 문학적 형상을 네 범주로 나누어 다루었다. 우리문학에서 동해는 첫째, 이 땅에 살았던 사람들의 의기를 거칠고 드세게 확충시켜 주었다. 둘째, 세상과 삶의 이치를 사유하고 통찰하게 하는 계기로 작용하였다. 셋째, 백두대간에서의 동해 조망은 국보 인식을 새롭게 해주었다. 넷째, 어촌민들의 고단한 삶이 펼쳐지고, 각종 풍속이나 교역이 활발하게 진행되는 삶의 현장이었다.

  • Sexual dimorphism in intelligence suggests that this phenotype is a sexually selected trait. This view is supported by an overrepresentation (compared to the autosomal genome) of genes affecting cognition on the X chromosome. The aim of this study is to test the hypothesis that sexual selection can explain sex and country-level differences in performance on tests of fluid intelligence. Nationally representative samples from N = 44 countries were obtained from the Programme for International Student Assessment (PISA) Creative Problem Solving (CPS), which evaluates the core of intelligence, that is novel problem solving ability. Sexual selection has the double effect of increasing the prevalence of a favored phenotype and reducing genetic variation in sexually selected traits. Matching these predictions from evolutionary theory, the average country fluid intelligence is positively correlated to sexual dimorphism after partialling out per capita GDP and the latter in turn is inversely correlated to variance in intelligence scores within populations. Males have a higher variance than females but there is a negative correlation between male-female difference in variance and sexual dimorphism in intelligence, suggesting that selection reduces variance more in the selected sex. Average country male height is negatively correlated to sexual dimorphism in intelligence, a fact that supports the notion of a trade-off between physical and intellectual competition in the context of access to females. The results of this study, if replicated, imply that genome-wide association studies of cognition may benefit from a focus on sex chromosomes, which so far have been neglected. Another implication of this study is that intelligence has continued to evolve after different human populations migrated out of Africa and possibly up to the 19th century, as suggested by the substantial variability in sex differences even between neighbouring countries.

  • The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).

  • Background: Brain volume is associated with dementia and depression in the elderly. An easy way to predict relative brain volume is to measure head circumference. In this study, we investigated the relationship between head circumference and cognition as well as depression in a non-demented elderly community. Methods: Baseline and follow-up surveys were conducted in 2007 and 2010. At baseline, community residents aged 65 years or over (n=382) within a rural area of South Korea were screened for dementia and symptoms of depression and were followed using the same screening battery after 3 years (n=279). Data from anthropometric measurements (head circumference, height, and body weight), demographics, and blood tests were gathered. Neuropsychological tests, including the Korean version of mini-mental state examination (K-MMSE), clinical dementia rating (CDR) including the CDR-sum of boxes, the Korean version of instrumental activities of daily living, and geriatric depression scale (GDS), were performed. None of the 279 subjects followed were demented. Results: Baseline performance on the K-MMSE and GDS was poorer for participants with smaller head circumferences. Follow-up performance on the MMSE was also poorer for participants with smaller head circumferences. Interestingly, participants with smaller head circumference showed worse GDS scores at baseline but on follow-up examination, participants with larger head circumference showed rapid worsening than those with smaller head circumference with marginal significance by ANOVA test. In regression coefficient analysis, GDS decline showed significant difference. Conclusion: Head circumference was not associated with cognitive change but was associated with symptoms of depression in non-demented community residents.

  • The purpose of this study was to assess the effect of visual block (eyes open or closed), mental task type, and participation in an exercise program on static balance in the elderly. The subjects were 34 elderly (>65 years old) residents of a social welfare institute in Gyeonggi-do. We measured the following variables. Berg balance scale, mini mental state examination, balance performance monitor (sway area, path, and maximal sway velocity), age, weight, height and whether the subject participated in an exercise program. Scores for the Berg balance scale and mini mental state examination were evaluated to assess static balance ability either alone (single task paradigm) or while performing a mental task (dual task paradigm). Static balance variables that were measured included sway area, path, and maximal sway velocity. Each test was repeated three times. Multiple regressions analysis was used to examine the effect of each variable on static balance ability. For the dual task paradigm, static balance was affected by whether the subject participated in an exercise program. The Berg balance scale score for subjects with their eyes open was affected by whether they participated in an exercise program, while this variable in addition to the height and weight of subjects were determining variables in subjects with their eyes closed. As a result, whether subjects participated in an exercise program affected their static balance irrespective of whether their eyes open or closed. Therefore, regular exercise is recommended for elderly people and further research is needed to examine the relationship between static and dynamic balance while performing mental tasks such as cognition and attention.
