`Bio morphism` are constituted in paintings where the artists try to embody the elementary properties of living creature as of growth and durability. They are the most appropriate concept of painting to harmonize human being with nature closely. The formative ways of them attach great importance to both unconsciousness and desire , as well as variations or dynamics, by noticing a flow of natural senses and feelings of human being. In other words, the formative ways are based on a recognition of nature as the intrinsic force of life, with the result that aesthetics of incompleteness is embodied in images. Therefore they are clearly distinguished from that of functional, geometric images. A tendency of painting at that time, in a word, 'return to figure and expression', means a conversion into organic images like the incomplete, atypical, and biomorphic forms, while denying the mechanical or geometric. Elizabeth Murray are analyzed, for these works are remarkable in the characteristics of 'Bio morphism'. Consequently the features of organic images, that is, 'the formative acceptance of natural figures, or an informality' and 'the force of free will, or an incompleteness', could obviously be revealed. It is a type that obtains a motif out of natural figures like an animal, a plant, or the concrete figures of human being. In conclusion, this thesis is focused on not only emphasizing that 'Bio morphism' were a major tendency among the various trends of postmodern painting in the 20th century, but also analysing both the painterly formation of organic images and the structure of them. In addition to these points, it is a central aim to evoke that Bio morphism should accurately be evaluated and positioned in postmodern painting. A new recognition of 'Bio morphism' is a peculiarity of the times that reflects a cultural aspect of the present, hence it should be recognized as another way to approach the postmodern painting.

The eco-design in modem fashion is mixed with a well-being trend that combines functionality and ethics with technology to suggest a new fashion style for the $21^{st}$ century. This study analyzes the colors of the eco-design in the current fashion trends and identifies the eco-friendly color images that suggest directions for eco-design. The results of this study are as follows. First, the eco-design is an ethical design concept of the ecological value. It can be classified into the functional efficiency in the multi-functionality the sustainability, the recycling capability, the trends for health and craftsmanship, according to various suggestions by eco-design related theorists. Second, the eco-colors shown in the fashion trend follow the order of YR, R, Y, N, and B, with the order of the pale, grayish, light grayish and dull tones. Third, the hue trends of eco-colors each eco-type are focused on R, YR, and Y. With regards to the tones, the functional efficiency, the multi-functional capability, and the sustainability are shown in the neutral tone, while the recycling capability is shown in the grayish tone and the trends pursuing health and craftsmanship are shown in the pale tone.

PET/CT combines the functional information from a positron emission tomography (PET) exam with the anatomical information from a computed tomography (CT) exam into one single exam. A CT scan uses a combination of x-rays and computers to give the radiologist a non-invasive way to see inside your body. One advantage of CT is its ability to rapidly acquire two-dimensional pictures of your anatomy. Using a computer these 2-D images can be presented in 3-D for in-depth clinical evaluation. A PET scan detects changes in the cellular function - how your cells are utilizing nutrients like sugar and oxygen. Since these functional changes take place before physical changes occur, PET can provide information that enables your physician to make an early diagnosis. The PET exam pinpoints metabolic activity in cells and the CT exam provides an anatomical reference. When these two scans are fused together, your physician can view metabolic changes in the proper anatomical context of your body. PET/CT offers significant advantages including more accurate localization of functional abnormalities, and the distinction of pathological from normal physiological uptake, and improvements in monitoring treatment. A PET/CT scan allows physicians to measure the body's abnormal molecular cell activity to detect cancer (such as breast cancer, lung cancer, colorectal cancer, lymphoma, melanoma and other skin cancers), brain disorders (such as Alzheimer's disease, Parkinson's disease, and epilepsy), and heart disease (such as coronary artery disease).

Scoliosis is a 3-dimensional spinal deformity defined as lateral curvature of the spine in the coronal plane of more than $10^{\circ}$. This study describes a case of functional scoliosis after hip injury. In this case, the patient fell whilst inline skating (June 2015) causing severe tilting of her spine, and left hip pain. She received outpatient treatment from July 14, 2015 to December 28, 2015. For approximately 5 months, acupuncture therapy was performed to relax the tension in both hips, Chuna therapy, and foot orthosis were applied to reduce the body's imbalance. Based on X-ray images, the Cobb angle had decreased from $14.73^{\circ}$ (pretreatment) to $1.90^{\circ}$ (posttreatment). This case report suggested that Korean medicine treatment could be an effective therapeutic choice for functional scoliosis.

The objective of this study is to analyze the characteristic of a functional design for a commercial outdoor brand jacket based on 3 types of functions : windproof, waterproof, and cold proof. To analyze the design and fabric characteristics of outdoor jackets by function, 903 men's and women's outdoor jacket images were selected from the catalogues during S/S 2009 - F/W 2011 of the 6 brands: The North Face, Columbia Sports Wear, Kolon Sports, K2, Arcteryx and Mont-Bell. These brands were selected based on their high market share and brand awareness of the outdoor brands in Korea. In this study, design elements analysis was conducted as following 8 elements: hood/collar height/central front flap/waistline/pocket location/ventilation for the body part/sleeve patterns/cuff for the sleeve part. Fabrics were analyzed by the frequency of fabric types used in the 3 jacket types. According to the result derived from the analysis of the six brands of outdoor wear jacket design trends by year, detachable hood and a co-use of velcro and elastic bands have been mainly designed for all of windproof, waterproof, and cold proof jacket to all in order to respond quickly to changes in the external environment. For reinforced storage function on trekking, the number of pockets has been gradually growing, and a function was being developed to connect an electronic device to a pocket. The method, result, and collateral observations relevant to each of these phases are described. Outdoor jacket design characteristics were investigated for outdoor brands, which can provide data to suggest more accurate functional design, and satisfy functional design needs. In this regard, this research was significant in the sense that it suggested preliminary data to reconsider competitiveness of the brand products.

목적 : 감각 및 운동기능에 대한 기능적 자기공명영상에서 데이터 분석 시 global scaling이 뇌 활성화 영상에 미치는 영향을 알아보고자 하였다. 대상 및 방법 : 신경학적 병력이 없는 정상 성인 피검자 4명을 대상으로 하였다. 운동기능은 오른쪽 상지를 구부렸다가 폈다가를 반복하는 운동을 시행하였고 청각기능은 1 KHz 순음자극을 시행하였다. 기능적 자기공명영상은 3.0T 자기공명영상기기(GE, Milwaukee, USA)에서 BOLD-EPI 기법을 사용하였고 데이터 분석은 SPM2를 사용하였다. 데이터 분석 시 움직임 보정, 통계적 유의 수준 등은 동일하게 한 상태에서 global scaling의 시행 전후의 뇌 활성화 영상을 획득하였다. 결과 : 오른쪽 상지운동에 대한 기능영상에서 global scaling 효과를 고려하지 않은 경우와 고려한 경우의 뇌 활성화 영상의 차이는 크지 않았다 (p<0.000001). 청각기능 검사에서는 global scaling 효과를 고려한 경우에서 고려하지 않은 경우에 비해 뇌 활성화 영상이 훨씬 크게 나타났다 (p<0.05). 결론 : 국소적 BOLD 신호의 변화가 작은 기능영상 검사에서는 데이터 분석 시 global scaling이 뇌 활성화 결과에 큰 영향을 미칠 수 있으므로 주의가 요구된다.

Objective : The purpose of this study was to investigate the factors affecting the surgical outcome and to compare the surgical results between transsylvian and transcortical approaches in patients with putaminal hematomas. Methods : Retrospective review of charts and CT scan images was conducted in 45 patients (20 transsylvian and 25 transcortical approaches) who underwent open surgical evacuation of putaminal hematomas. Mean Glasgow coma scale (GCS) score and hematoma volume were $7.5{\pm}3.2$ and $78.1{\pm}29.3\;cc$, respectively. The factors affecting the functional mortality were investigated using a multivariate logistic regression analysis. In addition, surgical results between transsylvian and transcortical approaches were compared. Results : None of the patients had a good recovery after the surgery. Overall functional survival rate and mortality were 37.7% and 31%, respectively. The only risk factor for functional mortality was GCS motor score after controlling age, history of hypertension, side of hematoma, hematoma amount midline shift, presence of intraventricular hemorrhage and surgical approach (p=0.005). Even though a transcortical approach was shorter in operative time (4.4 versus 5.1 hour) and showed a higher mortality rate (40% versus 20%) and lower functional survival (45% versus 35%) compared to the transsylvian approach, the differences were not statistically significant between the two groups. Conclusion : In patients who have large amounts of hematoma and require open surgical evacuation, the only significant risk factor for functional survival is the preoperative GCS score. Cortical incision methods such as transsylvian and transcortical approaches have no influence on the surgical outcome. To decompress the swollen brain rapidly, transcortical approach seems to be more suitable than transsylvian approach.

Tailored RF 경사자계 영상법을 이용하여 혈류효과를 배제한 자화율 효과만의 뇌기능 영상을 얻을수 있었다. 일반적인 RF를 이용한 경사자계 뇌기능 영상법은 빠른 경사자계 영상법으로 인해 정맥뿐만 아니라 동맥에서의 혈류효과와 $T2^{*}$ 효과가 합쳐진 영상을 얻게되는 반면, tailored RF를 이용한 경사자계 영상법은 산소소모와 관계된 자화율 변화에 의한 뇌기능 영상을 얻을 수 있었다. 본 논문에서 tailored RF를 이용하여 뇌기능 영상에서 자화율효과와 혈류효과를 명확히 구분할 수 있음을 보였다. 그리고 실험결과로 얻은 신호는 충분히 크고 산소 소모의 변화를 보다 더 정확히 표현하므로 지금까지 다른 경사자계 영상법으로는 어려웠던 뇌기능 영상에서 정량화된 산소 신진대사 연구의 가능성을 보여주었다.
