  • 공간적으로 3차원의 특성을 지닌 해양에서 수직적인 수온 자료의 특성을 가시화하기 위해서는 각 수심층별 수평 수온분포도와 같은 2차원적 주제도나 3차원적 공간보간을 통한 입체 모델을 사용하게 된다. 이러한 방법은 해양 현상을 시각적으로 이해하는데 유용하지만, 수직적 수온분포의 공간 패턴 분석이나 수직적 수온의 특성과 다른 해양 요인(해양화학, 해양생물, 기후변화 등)과의 관계분석에는 한계가 있다. 따라서 본 연구는 수온 수직구조의 주요 파라미터인 혼합층의 깊이, 최대수온구배, 수온약층의 두께를 추출하는 알고리즘을 이용하여, 수온의 수직구조 특성을 정량화함으로써 제주남부 해역의 수온 수직구조의 공간분포 특성을 밝히고자 한다. 이를 위해 수온 수직구조를 대표하는 세 가지 파라미터에 대한 공간분포지도 제작을 비롯해 공간자기상관 지수(Moran's I)를 계산하였다. 아울러, 세 가지 파라미터에 대한 군집분석을 수행하여 제주 남부해역을 4개 지역으로 그룹핑하고, 각 지역에 대한 수직 수온구조의 특성을 정의하였다.

  • As the elderly population are rapidly growing, the elderly who needs special care and nursing homes for them are also growing. However, many nursing homes were planned without considering the hierarchial space organization such as division of housing unit and nursing unit based on the cognitive and behavioral characteristics of the elderly or accessibility and supportiveness of the staff. This study was to examine the hierarchial characteristics in space organization of nursing homes by using Space Syntax. The subjects were 8 nursing homes in Busan. First, spaces in nursing homes were divided into five areas based on the literature review. Then the hierarchy of space organization for the access layer and layers of living floors was grasped by using G-graph. The access layer has a tree-type hierarchical structure and high visuality. Also, average depth of the space was 5. Then the full integration was analyzed. Mobile area, such as elevator, hallways, or living rooms has a high accessibility and the middle corridor type has commonly been characterized. The nursing stations were analyzed through the control degree and it was low in three nursing homes such as B, C, and G. The low clarity was showed in B, D, and F. The low clarity means that it is relatively difficult to recognize the whole space organization of nursing home. Even though the hierarchy of their living floors was tree-type structure with a high visuality, they has a type of grouping spaces around hallways and spreading, or a ring type.

  • Objectives: This study aimed to examine the difference of external appearance measurements in subjects of different regional lineages as subgroups within the Tae-eumin Sasang grouping. Methods: We chose 51 Tae-eumin subjects diagnosed by Korean Sasang constitutional medical doctors aided by voice analysis. The subjects were divided into two groups, the northern and southern lineages, by an expert on facial characteristics of the two lineages. We took pictures of their frontal and lateral views by Martin's method, measured projected length of face with the Facial Feature Measurement Program, and analyzed anthropometric facial differences between the northern and southern types. Results: Results show differences between the northern and southern types. First, the northern type of face has bigger measurements than the southern type on the frontal face. Second, the northern type of face has higher measurements of "height", which means distance from pupil to a specific measurement point, than the southern type on the frontal face. Third, on the frontal face, the northern and southern types have differences with respect to eyebrow, point of sellion, and eye. Fourth, on the side face, the northern and southern types have differences in lip, mandible and ear. Conclusions: We found our anthropometric facial measurements of the northern and southern lineages to be in accordance with previous literature. Knowledge of the differences between the northern and southern lineages can be a hint in constitutional diagnosis when differentiation is clinically confusing.

  • The phylogenetic tree displayed the presence of five groups in the Phellinus genus, which were distinguished based on their morphology. Most of the p. linteus appeared a cluster which was highly significant with the exception of P. linteus KACC 500122 and KACC 500411. They formed the sister taxa of P 1inteus where P. baumii, Phellinus sp. MPNU 7003, MPNU 7007, and MPNU 7010 had similar morphological characteristics. Also, P. nigricans IMSNU 32024 and P. pini var, carniformans IMSNU 32031 were grouped in the same cluster with P. igniarius KCTC 6227, KCTC 6228, and P. chrysoloma KCTC 6225 extracted from the Gen-Bank database. P. torulosus IMSNU 32028 and Phellinus sp. MPNU 7011 formed a closed group, however, these species had a distant taxa when compared with the other Phellinus species. The nucleotide sequences of the internal transcribed spacer (ITS) regions of ribosomal DNA (rDNA) including the 5.85 rDNA were determined from 24 strains of the Phellinus genus in order to analyze their phylogenetic relationship. These fungi were divided into two basic groups based on their ITS length, however, this grouping was different from that based on their morphological characteristics. Although various ITS sequences were ambiguously aligned, conserved sites were also identified. Accordingly, a neighbor-joining tree was constructed using the nucleotide sequence data of the conserved sites of the ITS regions and the 5.8S rDNA.

  • As a preliminary research of body characteristics analysis of Korean obese woman, this study aims to select optimal obesity judgment tools for reliable sampling of obese subjects from 2,425 female measurement data out of 2004 Size Korea project's raw data. From previous researches related to obesity, 7 obesity judgment tools were chosen. 2007 obesity rate(26.3%) of Korean female adults was refered in selecting optimal obesity judgment criteria in the study. The results are as follows. Firstly, it was verified that BMI was the most suitable in judging and sampling the obese subjects by the percentile analysis. R$\ddot{o}$hrer index was also reliable in grouping the obese subjects from a population. Secondly, it was concluded that the obesity ratios of relative weight 120 and higher group, R$\ddot{o}$hrer index 1.6 and higher group and waist girth 80cm and higher group were the most similar to obesity rate of Korean female adults by 2007 National Health & Nutrition Survey. Thirdly, 30 direct measurements, age, 2 drop values and 6 ratios of 7 groups by the obesity judgment tools showed the significance each other at p<0.001 level. On the other hand, "bust point to bust point" and "waist to hip length" measurements didn't show the significant differences among 7 groups. Conclusively, 4 to 5 satisfactions out of 7 obesity judgment criteria were adequate and sufficient in sampling the obese subjects. If it is needed the strict criteria for judging the obesity, 5 satisfactions and higher group will be the best choice as the obese subjects. However 4 satisfactions and higher group generally, will be adequate for sampling of the obese subjects.

  • This study examines the appearance management attitude factor of male college students and groups them according to their characteristics. Then this research analyzes their interest in knitwear, buying behavior, and characteristics to see what kind of differences exist. The results of the research are as follows: First, after conducting a factor analysis to identify the appearance management attitude of male college students, 3 factors emerged(sought personality, pursued trends, and appearance interest). Second, as a result grouping the students according to their attitude. It is created 3 groups(fashionista group, personality group, and appearance interest group). Third, for the interest in knitwear, the fashionista group had the highest interest in knitwear, with a preferred brand when purchasing. Fourth, the fashionista group that values personality and latest trends was more likely to purchase knitwear than the personality group or the appearance interest group. Finally, the majority preferred solid colors. Over 50% of the students preferred knits without any patterns. Also, the most preferred 100% cotton. As this survey was only surveyed in Seoul and Gyounggi areas. The next research requires to be surveyed in a more comprehensive area. Additionally, male college students must more effectively be segmented and surveyed to get accurate results.

  • This study divides female consumers according to eco-friendly attitudes and the purchase frequency of eco-clothing products; in addition, it analyzes the characteristics of each group in terms of LOHAS lifestyles, the attitudes for eco-clothing products, and satisfaction. Eco-clothing attitudes of female consumers were lower than eco-friendly attitudes. A total of 360 female consumers were divided into 4 group according to purchase frequency and the eco attitude, Type 1: survival (33.0%), Type 2: wellbeing (25.6%), Type 3: curious (15.0%), Type 4: LOHAS (26.4%); in addition, age, income, marit alstatus, occupation, LOHAS lifestyle and shopping places were differentiated by type. Type 1 (low eco attitude and low eco-clothing purchase) were composed of the youngest, college students, low income, low level of LOHAS lifestyles and low level of eco-clothing attitude. Type 2 (high eco attitude and low eco-clothing purchase) were interested in healthy eating & exercise among LOHAS lifestyles; in addition, Type 1 & 2 showed alow level of eco-clothing satisfaction. Type 3, low eco attitude and high eco-clothing purchase, were characterized with high expenditures on clothing relative to income as well as lower levels of family activities and leisure life than LOHAS Type 4. Type 4 (high eco attitude and high eco-clothing purchase) were the oldest group and mostly composed of married workers (the highest income) with the highest LOHAS lifestyles and the highest level of eco-clothing satisfaction.

  • 컴퓨터 애니메이션을 이용한 군중 장면은 영화나 게임에서 자주 등장한다. 군중의 보행동작을 생성하기 위해 기존의 기술들은 주로 군중의 각 개체들의 행동을 모델링하여 접근하였다. 하지만, 군중의 규모가 커질수록 모든 개체를 개별적으로 제어하기는 어려워진다. 따라서 대규모 군중의 경우 개체별로 행동을 모델링하기보다 집단별로 모델링하여 보다 직관적으로 군중을 제어할 수 있다. 본 논문에서는 집단의 경로 추적 행동을 시뮬레이션하기 위한 집단 역장 모델을 제안한다. 집단은 같은 목적, 즉 같은 경로를 따라 무리지어 행동하는 개체들의 모임으로 정의된다. 또한 집단의 무리짓는 행동은 정렬, 응집, 분리의 세 가지 특징으로 규정지을 수 있다. 집단 역장 모델을 통해 이러한 집단의 특징들을 보존하면서 개체 간의 충돌을 자연스럽게 회피할 수 있다. 제안한 기술을 통하여, 사용자는 나란히 늘어선 집단에서 동그랗게 뭉쳐진 집단까지 원하는 형태의 경로 추적 애니메이션을 생성할 수 있다.
