  • 본 연구는 기계식 환기장치에 의한 선박 선실 내의 환경오염물질 확산특성을 파악한 것으로, 연구성과는 다음과 같다. 오염발생 선실 내에서는 오염발생 35분 경과 후 오염물질이 대부분 제거되었고, 신선외기 도입율 변화에 따른 영향은 무시할 수 있었다. 오염원 선실에 인접한 선실의 오염물질 제거시간은 65분~100분 정도로 신선외기 도입율에 따라 차이가 발생했다. 상부 데크에 오염원 선실이 있는 경우가 하부 데크에 오염원 선실이 있는 경우에 비해, 오염농도는 10배 정도 높지만, 대표 공간 중 오염된 공간의 수는 오히려 1/2에 불과했다. 그러나 전체공간을 대상으로 한 평가에서는, 상부 데크에서 오염물질이 발생한 경우에는 Upper 데크 이상 상부 데크 내 공간의 50% 이상이 평가기준 0.001%, 0.01%, 0.1% 일 때 오염될 것으로 예측되었고, 하부 데크에서 오염물질이 발생하는 경우에는 하부 데크를 중심으로 오염공간이 많지만 오염판단기준 0.01%일 때에는 Shelter 데크 이상의 상부 데크에서도 오염선실이 나타났다. 한편, 신선외기 도입량 변화에 따른 오염농도 및 오염공간 비율을 분석한 결과 설계용량 대비 75% 이상의 외기가 도입될 때 선실 내 오염수준이 낮아지는 것으로 평가되었다.

  • This study has surveyed and analyzed in 2005 S/S domestic men's street fashion by using the Web-SFAS system that was developed and completed in the earlier research. Total of 270 men who were sensitive to fashion were surveyed around 5 nationwide cities and 9 commercial zones. The analysis results of the questionnaire and image survey in 2005 S/S for each commercial zone was shown as follows. 1. The most interest in producing fashionable shape when they go out was in the order of clothes>hair style>shoes and it was found that the proper reason for visiting the commercial zone was to meet with friends>watching movies>shopping etc. 2. T-shirts were most preferred as upper garments and as for bottoms, blue jeans were preferred. Black, gray, and white colors were most preferred and blue color was most preferred primarily due to the preference for blue jeans. The color image was proven mainly modem and light tone, comfortable and casual items were preferred. An active comfort casual image emphasized with activeness by coordinating comfortable T-shirts or shirts with blue jeans were most preferred in 9 areas. 3. A clear difference was confirmed in color by commercial area. Blackish color was most prevalent in Daehakro whereas simple color was mostly shown around Hongik University area. Bright and unique colors such as green and violate were dominant at Dae-Gu Dongseongro, and basic colors such as white and black were preferred in Masan Hapseong-dong and Changwon Sangnam-dong. Through the results of nationwide street fashion survey, the each commercial zone has unique characteristics in fashion trend even in the same city, rather than the regional difference in Seoul and local city.

  • The development of reticulum in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. In the 60-day-old fetuses, the stomach was developed and differentiated into four compartments of rumen, reticulum, omasum, and abomasum. The reticular epithelial layers were differentiated into two zones; a small dark basal and a large light luminar zones. The wall of reticulum resembled that of the rumen except that the mucosa was in the cranio-dorsal region of the reticulum. 2. In the 90-day-old fetuses, the light luminar zone of the reticulum was about 10-16 times thicker than the dark zone. The outlines of the reticular ribs were visible. 3. In the 120-day-old fetuses, the wall of the reticlum had also increased in thickness. The reticular mucosa exhibited an irregular luminar surface and the invaginations had differentiated into large regularly arranged ones separated by 3-5 and small irregularly arranged ones. 4. In the neonate, the luminar surface of the reticular mucosa demonstrated clear furrows, at which the superficial cells of the light zone had undergone degenerative changes. 5. Scanning electron microscopic studies; In the 60-day-old fetuse, numerous microvilli were observed on the superficial epithelial layer of shape or dome like at 120 days. In the neonate, the reticular papillae liked the little finger.

  • 한국 남부에서 섭입 해구의 방향과 나란히 쌍으로 발달한 화산대가 발견된다. 경상분지와 영동-광주 함몰대의 화산암류는 거의 나란한 양상을 보이며, 이들은 각각 동일한 섭입 체계에 따르는 첫 번째 화산대, 두 번째 화산대이다. 경상분지와 영동-광주 함몰대 화산암류의 불호정성 원소 함량은 호를 가로지르는 변화를 뚜렷하게 보인다. 즉, 첫 번째 화산대 (경상분지 및 남해안 도서지역)용암들의 불호정성 원소 함량은 두 번째 화산대 (영동-광주 함몰대)에 비해 더욱 결핍되며 두 번째 화산대에서 더욱 증가하는 경향을 보인다. 이와 같이 호를 가로지르는 변화를 보이는 것은, 탈수과정 동안 유체상과 공존하는 고체상의 차이에 기인한 것으로 보인다. 두 번째 화산대의 불호정성 원소의 함량, Zr/Y 비, Rb/K 비는 첫 번째 화산대에 비해 더 깊은 깊이에서 더 적은 정도의 부분 용융, 그리고 용융 과정에서의 잔류 석류석에 기인할 것이다.

  • 이 연구에서는 중앙지와 지역일간지가 인천경제자유구역 개발 뉴스를 어떻게 보도했으며, 이 과정에서 언론이 어떤 방식으로 역할을 했는지를 살펴보았다. 중앙지와 지역일간지 간에 현실 재구성, 뉴스보도 가치 등의 차이점을 발견하는데 주력했다. 보도방식은 고전적인 형식에 최근 경향을 적절히 반영하고 있음이 확인됐다. 지역 현안을 바라보는 조선일보의 시각은 찬 반의 명확한 태도에서 벗어난 중간자적 입장을 취했으며 반면 경인일보는 감시자의 입장에 서 있었다. 즉 전국을 취재 권역으로 한 중앙지는 지역 이슈에 대해 관망적인 자세를 보였고, 해당 지역을 중심으로 기사를 작성하는 지역일간지는 적극적인 보도 태도를 취했다. 이런 뉴스구성 태도는 실제 지면으로 이어지는 기준인 뉴스가치에도 그대로 반영됐다. 조선일보는 정치적 영향성에, 경인일보는 문화적 유사성에 집중하고 있었으며, 인천경제자유구역 개발 뉴스는 매체 간 구분 없이 대체적으로 경제적 중요성과 인간적 흥미성은 높았고 선정성 및 규범적 일탈성은 낮았다.

  • Lumbar segmental instability is considered to represent a significant sub-group within the chronic low back pain population. This condition has a unique clinical presentation that displays its symptoms and movement dysfunction within the neutral zone of the motion segment. The loosening of the motion segment secondary to injury and associated dysfunction of the local muscle system renders it biomechanically vulnerable in the neutral zone. There in evidence of muscle dysfunction related to the control of the movement system. There is a clear link between reduced proprioceptive input, altered slow motor unit recruitment and the development of chronic pain states. Dysfunction in the global and local muscle systems in presented to support the development of a system of classification of muscle function and development of dysfunction related to musculoskeletal pain. The global muscles control range of movement and alignment, and evidence of dysfunction is presented in terms of imbalance in recruitment and length between the global stability muscles and the global mobility muscles. The local stability muscles demonstrate evidence of failure of aeequate segmental control in terms of allowing excessive uncontrolled translation or specific loss of cross-sectional area at the site of pathology Motor recruitment deficits present as altered timing and patterns of recruitment. The evidence of local and global dysfunction allows the development of an integrated model of movement dysfunction. The clinical diagnosis of this chronic low back pain condition is based on the report of pain and the observation of movement dysfunction within the neutral zone and the associated finding of excessive intervertebral motion at the symptomatic level. Four different clinical patterns are described based on the directional nature of the injury and the manifestation of the patient's symptoms and motor dysfunction. A specific stabilizing exercise intervention based on a motor learning model in proposed and evidence for the efficacy of the approach provided.

  • This paper aims to estimate the range of the excavation damaged zone (EDZ) formation caused by the tunnel boring machine (TBM) advancement through dynamic three-dimensional large deformation finite element analysis. Large deformation analysis based on Coupled Eulerian-Lagrangian (CEL) analysis is used to accurately simulate the behavior during TBM excavation. The analysis model is verified based on numerous test results reported in the literature. The range of the formed EDZ will be suggested as a boundary under various conditions - different tunnel diameter, tunnel depth, and rock type. Moreover, evaluation of the integrity of the tunnel structure during excavation has been carried out. Based on the numerical results, the apparent boundary of the EDZ is shown to within the range of 0.7D (D: tunnel diameter) around the excavation surface. Through series of numerical computation, it is clear that for the rock of with higher rock mass rating (RMR) grade (close to 1st grade), the EDZ around the tunnel tends to increase. The size of the EDZ is found to be direct proportional to the tunnel diameter, whereas the depth of the tunnel is inversely proportional to the magnitude of the EDZ. However, the relationship between the formation of the EDZ and the stability of the tunnel was not found to be consistent. In case where the TBM excavation is carried out in hard rock or rock under high confinement (excavation under greater depth), large range of the EDZ may be formed, but less strain occurs along the excavation surface during excavation and is found to be more stable.

  • Background: Research on the reproductive physiology of Water and Sika deer, an endemic in Korea, still needs to be completed. This study analyzed the ovarian development and morphological characteristics of wild Water deer and Sika deer. Methods: Water deer and Sika deer ovaries were collected from the Korean Peninsula and Russia-Korean Peninsula border during the estrus and pregnancy seasons, respectively. And, morphological and physiological analysis and immunohistochemistry were conducted to confirm the detection of Ca2+ and assess the morphological changes in the ovaries. Results: The results of morphological analysis of ovaries during pregnancy and estrus, the development of the corpus luteum and follicles of Water deer showed similar patterns to other mammals. In contrast, the corpus luteum of Sika deer differed in tissue morphology and composition from Water deer. Ca2+ related to tissue metabolism was detected in the theca cells zone of Water deer on the estrus and was highly detected in the luteum cells zone during pregnancy. The hormone receptor protein expression patterns were generally higher in the ovaries of Water deer on the estrus and the pregnancy than in Sika deer. The expression of LH receptor was relatively low in the lutein cell zone, unlikely that of Water deer. The expression of VEGF was also different from Water deer, and the response in Sika deer was relatively very low compared to Water deer in expressing all proteins-related development. Conclusions: Therefore, the results of the study were shown that the composition of the corpus luteum of Sika deer is not clear compared to Water deer, and there are many differences in the functional and morphological formation of the corpus luteum.
