This study analyses the characteristics of volatile organic compounds (VOCs) emissions from the painting and printing facilities, as well as ambient VOCs at industrial complexes in Gwangju. The major components of VOCs emissions from painting facilities were toluene, acetone, 2-butanone, ethyl acetate, ethyl benzene, o-xylene and m,p-xylene. The printing facilities mostly emitted ethyl acetate, 2-butanone, acetone and toluene. Aromatics (49.9%) and oxygenated VOCs (43.6%) were dominant in painting facilities, while oxygenated VOCs (92.7%) were the largest group in printing facilities. The total hydrocarbon concentration (THC) in printing facilities was approximately six times higher than in the painting facilities. The painting and printing facilities use many solvents. Their THC concentrations differed considerably depending on the type of prevention facilities. To reduce THC, it is necessary to improve the prevention facilities and operating conditions. The dominant species of ambient VOCs in industrial complexes were investigated with toluene, ethyl acetate, 2-butanone, ethyl benzene, m,p-xylene, butyl acetate, o-xylene, hexane and acetone. Factor analysis of ambient VOCs showed that the main sources of the VOCs were organic solvents used in painting, coating, and printing, as well as automobile emissions.

In this study, a 16-week exercise program was conducted for 19-29-year-old women with scoliosis deformity, and it was found to have a positive effect on the subjects body composition, body alignment and balance ability. Until now, spinal disease has been considered a geriatric disease, but as the age of onset continues to decrease, it is considered that various studies are needed for the prevention and improvement of spinal diseases. However, in this study, the amount of physical activity and exercise were not restricted in the non-exercise group, and the diet and the cervical spine angle were not considered in the exercise group and the non-exercise group. Therefore, it is considered that it is necessary to develop and distribute an exercise program that considers all of the above factors through follow-up studies.

본 설계안은 2014년 수도권 매립지 드림파크 국화축제를 위한 기본계획안이다. 대상지의 면적은 약 $560,000m^2$이며, 인천광역시 서구 백석동 58번지 드림파크 녹색바이오 단지 일대에 위치하고 있다. 작년 153만 명의 방문객을 유치한 드림파크 국화축제를 위해 이 설계안은 전체적인 마스터플랜과 상징적인 토피어리들과 함께 계획된 다양한 식재계획들을 포함한다. 이 설계안의 목적은 축제를 통해 매립지의 이미지를 개선하고, 지역가치와 지역경제를 향상시킬 뿐만 아니라, 2014년 아시안 게임을 기념하는 경관을 조성하는데 있다. 이 목적을 위하여 세 가지 설계목표가 설정되었는데, 우선 인천의 지역성을 부각시켜 지역 자부심을 높이고, 기존 축제 브랜드 이미지에 부합하는 경관미적 가치를 제시하며, 끝으로 지속가능한 공간조성을 하는 데 있었다. 좀 더 세부적으로 첫째, 지역 자부심 향상을 위해 인천대교에서 영감을 얻은 2km 길이의 "리틀 인천" 데크브릿지가 야생화 군락지위로 제안되었으며, 다양한 지역 참여 정원 프로그램들이 부지 동측에 계획되었다. 또한 비정형적 레크레이션과 문화활동을 위한 커뮤니티 공간을 제공하여 사람 중심의 매립지 개발에 대한 비전을 제시했다. 둘째, 축제의 미적 브랜드 가치를 향상시키기 위해, 부지 전체에 야생화 군락들을 조성하였다. 부지 중심에는 아시아 전래동화들을 주제로 한 가을 초화류와 지피류 식물군의 식재 연출을 통해 축제의 하이라이트를 마련하였다. 그리고 코스모스 대형 군락지로 하여금 축제의 브랜드 이미지를 강조하고, 이미지에 대한 기억으로 관객들의 재방문을 유도하였다. 셋째, 지속가능한 환경조성을 위해 기존 갈대밭과 식재를 보존하면서 자연적 레이어들을 중첩하여 경관 연출을 하였다. 더불어 시설물과 서비스 센터들은 사용자의 수요에 맞게 유동적으로 설계되고 배치되었으며, 효율적이고 경제적인 운영을 위한 축제관리계획을 제안하였다. This paper offers a landscape design proposal for the 2014 Dreampark Chrysanthemum Festival within the Sudokwon Landfill Site. This site is located at 58 Baeksukdong, Seo-gu, Incheon, and it has an area of approximately $560,000m^2$. Over 1.53million visitors came to this festival on the previous year. This design includes an overall masterplan and a series of planting plans along with a core selection of iconic topiaries. The goal of the design is to create a landscape that improves the value of the place image and local economy as well as celebrates the 2014 Incheon Asian Game. In order to achieve this goal, three design subjects were considered: promoting local pride as a part of Incheon, increasing the aesthetic value of the site based on the brand image, and sustainable placemaking. To promote local pride, the 2km long "Little Incheon" is designed over a wildflower field, which is inspired by Incheon Bridge to give a strong image of the locality. A variety of programs from local gardening participation were introduced to the east part of the site. The design also outlines the vision for the development of Dreampark - a people-oriented gathering place for the entire community with spaces that offer a variety of unstructured recreational and cultural experiences. To increase the aesthetic brand value of the festival, it introduced a variety of wildflower beds scattering through the whole site. It creates a strong brand image for the festival and memories that will encourage visitors to return. Various folktales of Asian countries are displayed by autumn flowers and groundcover plants at the centre of the site, which is the highlight of the festival site. For sustainable placemaking, the design preserves the existing trees and reed beds for wildlife to create natural layers of landscape. In addition, facilities and service centers are designed to be flexible and are centred on the needs of the people using them. Also a festival management scheme was planned in order to operate the site efficiently and economically.

국내에서 육종한 11가지 고구마의 전분 특성을 구명하여 새로운 식품 소재의 개발을 위한 기초자료로 이용하고자 전분의 이화학, 호화 및 소화 특성을 조사하였다. 아밀로스 함량은 12.5-17.4%의 범위를 보였으며, 아밀로펙틴 가지 사슬 분포는 시료 간에 유사하였다. 증미 전분의 아밀로펙틴 분자량이 가장 컸으며 대유미 전분은 가장 낮은 값을 보였다. 모든 고구마 전분의 X선 회절 양상은 C형 중에서도 A형에 가까운 C<SUB>a</SUB>형을 나타내었다. 시차주사열량계로 측정한 열 특성에서 11품종 고구마 전분 중 신율미와 증미의 호화 온도가 높았고, 해피미는 낮았다. Rapid Visco Analyser로 페이스트 특성을 살펴보았을 때, 호화시간은 전분 입자의 크기, 최고점도, 강하점도와 음의 상관을 나타내었으며, 해피미가 가장 낮은 호화 온도와 치반점도를 보였고 강하점도와 최고점도 및 최종점도가 높았다. 소화 특성에서 증미의 RS 함량이 가장 많았으며, 신율미와 해피미는 SDS 함량이 많았다. Physicochemical, pasting, and digestion properties of sweet potato starches from 11 Korean cultivars were investigated. Starch granules were variably oval, round, polygonal, spherical, and bell-shaped, and of 10.2-15.3 μm in mean particle diameter. Amylose contents varied from 12.3 to 17.4%. A similar chain length distribution of amylopectin was found in each of the cultivars. The portion of B3 correlated with the degree of amylose leaching. Thermal properties determined by differential scanning calorimetry showed high values of gelatinization temperatures in Shinyulmi and Jeungmi starches, but a relatively low value in Daeyumi starch. All starches exhibited a Ca-type diffraction pattern. Differing patterns were observed in swelling factors, depending on temperature. The contents of rapidly digestible starch, slowly digestible starch, and resistant starch ranged from 9.6-17.4, 31.4-45.6, and 35.7-62.8%, respectively. In Rapid Visco Analyser profiles, differences were observed in pasting parameters such as pasting temperature, peak viscosity, final viscosity, and breakdown.

목 적: 데스모이드 종양의 수술 후 방사선치료 성적을 분석하고 예후인자를 평가하기 위하여 후향적 연구를 진행 하였다. 대상 및 방법: 1984년 6월부터 2005년 10월까지 서울대학교병원에서 데스모이드 종양으로 수술 후 방사선치료를 시행 받은 환자 27명에 대한 의무기록을 분석하였다. 남자 13예, 여자 14예였으며 연령은 3∼79세였다(중앙값, 28 세). 종양은 복부 외(21예), 복벽(6예)에 위치하였고 종양의 크기는 장경 기준 2.5∼25 cm (중앙값, 7.5 cm)였다. 첫 수술 후 방사선치료를 받은 환자가 13예, 국소 재발 종양에 대한 반복 수술 후 방사선치료를 받은 환자가 14예 였다. 방사선치료는 분할 선량 1.8∼2.0 Gy로 총 45∼66 Gy (중앙값, 59.4 Gy)를 조사하였다. 결 과: 추적관찰 기간의 중앙값은 61개월(범위, 12∼203개월)이었다. 병변의 국소 진행은 2예에서, 국소 재발은 6예에서 관찰되었다. 5년 무병생존율과 5년 무진행생존율은 각각 61%와 70%였다. 다변량 분석 결과 광범위절제술을 시행한 경우 용적축소수술을 시행한 경우보다 무병생존율이 높았고(p=0.028), 첫 수술 후 방사선치료를 시행하는 경우와(p=0.046) 방사선 선량이 60 Gy 이상인 경우에(p=0.049) 무진행생존율이 높았다. 첫 수술 후 방사선치료를 시행한 경우 최종 관찰까지 수술 횟수가 중앙값 1회(범위, 1∼3회)였으나 첫 수술 후 방사선치료를 시행하지 않은 경우 수술 횟수가 중앙값 3.5회(범위, 2∼6회)였다(p<0.001). 결 론: 처음 진단 시 수술 후 방사선치료를 시행한 경우 국소 제어율은 높았고 총 수술 횟수는 적었다. 따라서 재발의 위험도가 높은 용적축소수술을 받은 환자 등에서는 수술 후 조기 방사선치료의 시행이 바람직하다. Purpose: This retrospective study was conducted to assess outcome and to determine the prognostic factors in patients with a desmoid tumor treated with postoperative radiotherapy. Materials and Methods: Twenty-seven patients with a desmoid tumor who were treated with postoperative radiotherapy between June 1984 and October 2005 were analyzed. There were 13 male and 14 female patients. The age of the patients ranged from 3 to 79 years (median age, 28 years). Tumors were located in an extra-abdominal area (21 cases), and in the abdominal walls (6 cases). The tumor size ranged from 2.5 to 25 cm (median size, 7.5 cm) in the largest linear dimension. Thirteen cases received radiotherapy after initial surgery, and 14 recurrent cases received radiotherapy after additional surgery. The total radiation dose given was 45∼66 Gy (median dose, 59.4 Gy), and the fraction size was 1.8∼2.0 Gy. Results: The median follow-up period was 61 months (range, 12∼203 months). Two patients developed local progression and six patients experienced local recurrence. The 5-year disease-free survival rate and the 5-year progression-free survival rate were 61% and 70%, respectively. Wide local excision was associated with better disease free survival with statistical significance (p=0.028). Radiotherapy after initial surgery (p=0.046) and a higher radiation dose of more than 60 Gy (p=0.049) were associated with better progression free survival with statistical significance. At the time of the last follow-up, the number of additional surgeries was higher in patients that received radiotherapy after reoperation (p<0.001). Conclusion: Radiotherapy after the initial operation improved local control and decreased the number of subsequent operations. Thus, postoperative radiotherapy after an initial operation is recommended in patients with a high risk of recurrence for a desmoid tumor.

If the lifting power of eyelid from the levator palpebrae muscle becomes weak, eyelid is drooped and the edge of eyelid cannot be lifted on normal level. This phenomenon is called the ‘Ptosis’. If the person has the ptosis, they use the forehead muscle when the eyes open. In this research, the frontalis EMG was measured for the gaze angle. People with the ptosis was confirmed for the use frontalis muscle more than normal people. Therefore, we propose a system to quantify the presence the ptosis as EMG levels of frontalis muscle.
