朱星嬉 服飾文化學會 1994 服飾文化硏究 Vol.2 No.2

The mask used in drama has been reappreciated, and it needs profound and systematic studies in order to from the mask to effective use. In research, the aesthetic values in the masks of the latter period of Chosun(the mideighteenth century-the early nineteenth century) was examined through the analysis of traditional drama in accordance with the historical social background. In the latter period of Chosun, the active performance of the mask in company with the occurence of a popular movement caused by people's self-awakening showed a close relationship between the development of the mask and its historical background the moulding characteristic of the mask was analysed before and after the eighteenth century, and regionally in the south and in the middle and the north. The mask express the quality of art before the eighteenth century and a high social nature after the eighteenth century. It showed, on the other hand, a strong social nature and a touch of satires on society in the south and a religional interest in the middle and the north. This study shows from the viewpoint of a aesthetics that tradtional Korean mask during Chosun period had comfortable and voluminous forms with beauty curved lines and colors and rhythm. The aesthetic values in mask as experssed through The aesthetic characteristics have been classified the beauty of nature the beauty of personality, thebeauty of tradition. Visual image with these beautys in masks were expressed into fashion of suits and drcsses.

Prevertebral soft tissue swelling of cervical spine lateral radiogram is well known as an indirect evidence of occult cervical spine injury. But the clinical and statistical value of it has been of debate. We tried to analyse the value of cervical prevertebral soft tissue width as a screening test for cervical spine injury by comparison of two categorized study groups; the control group, traumatized patients without cervical spine injury and the injury and the injury group, traumatized patients with bony cervical injury. The injury group consisted of patients admitted between September 1993 and December 1994 with an ED diagnosis of bony cervical injury. The control group consisted of patients admitted between January 1994 and June 1994 who received cervical spine lateral radiograph because of suspicion of cervical spine injury or as a routine check. In both group, we sampled the patients who received cervical spine lateral rediograph within 24 hours after injury and excluded the patients less than 15 years old and more than 65 years old, In the control group, we confirmed the patients had no problem in cervical spine of follow-up. 101 control patients and 68 injury patients were identified. The injury group was further divided into two subgroups: those with injuries at C1-C3 to the upper injury subgroup and those with injuries at C4-C7 to the lower injury sub group. The prevertebral soft tissue widths of injury group were larger than of control group at C2(mean 6.1mm versus 4.5mm) and also at C6(mean 13.4mm versus 11.2mm). Especially upper injury subgroup had quite large value of C2 prevertebral soft tissue width(mean 14.1mm). Nevertheless, both in C2 and C6, there is no cutoff value with acceptable sensitivity and specificity as a screening test. But the 7mm at C2 and 14mm at C6 had high specificity(90%) and were thought to be a good radiologic indicators of further evaluation.

유치열과 혼합치열기 어린이의 상악 절치부 외상

정주현,이제호,김성오,최병재 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

현대인의 생활양식과 환경이 도시화 및 인공화되고 취미활동이 다양화됨에 따라 외상을 받을 수 있는 요인들을 증가하고, 특히 어린이 활동량이 많아져 외상의 기회가 잦아지고 있다. 어린이에서 외상이 발생하는 경우, 어린이의 일상적인 활동 뿐 아니라, 사회성 및 정서 발달에도 영향을 미칠 수 있으며, 그 보호자에게도 부정적인 영향을 미칠 수 있기에 외상의 발생 빈도를 줄이고 예방하는 것이 중요하다. 본 연구는 유지열과 혼합치열기에 발생하는 치아 외상을 예방하기 위한 기초 자료를 얻기 위하여, 특히 구강악안면부의 외상시 치아 외상을 가장 많이 받는 상악 유절치와 영구절치를 연구하기 위하여, 2002년 6월부터 2003년 5월까지 연세대학교 치과대학병원 소아치과에 내원한 유치열과 혼합치열기의 신환 8.799명중 상악 절치부 외상을 주소로 내원한 어린이 487명(남자 316명, 여자 171명)의 상악 절치 955개(유절치543개, 영구절치 412개)를 조사하여 다음과 같은 결과를 얻었다. 1. 상악 절치부 외상이 호발하는 나이는 유절치에서 1~3세, 영구절치에서 7세였으며 남자대 여자의 비율은 1.85:1이었다. 2. 상악 절치부 외상은 유절치와 영구절치 모두 오후 시간에 많이 발생하였으며, 유절치는 외상 장소로 집이 가장 많았고 (44.1%), 영구절치는 길에서 다치는 경우가 가장 많았다(17.5%). 3. 외상의 원인으로 유절치와 영구절치 모두 넘어져 다치는 경우가 가장 많았으며(39.8%, 12.9%), 다음으로 부딪히는 경우가 많았다(22.2%, 6.0%). 유절치에서는 다음으로 떨어져 다치는 경우, 교통사고, 폭력과 운동에 의한 외상 순이었으며, 영구절치에서는 폭력, 운동, 교통사고, 떨어져 다치는 순이었다. 4. 조사대상 어린이 1명당 유절치는 1.6개, 영구절치는 2.8개에 외상을 입었다. 5. 유절치와 영구절치 모두에서, 치관 파절 양상은 치수미노출 치관 파절이 많았고, 치주조직 외상 양상은 아탈구가 가장 많았다. 최근 어린이의 단체 생활이나 운동과 취미 활동에 참여하는 나이가 예전에 비하여 점차 낮아지고 있어, 이번 연구 결과와 같이, 외상이 발생하는 나이 역시 지속적으로 낮아질 수 있다. 나이에 따른 어린이의 외상을 받는 장소는 특별한 곳이 아닌, 집이나 학교와 같은 일상의 생활공간이기 때문에 단순한 주의만으로도 외상의 발생을 예방할 수 있을 것으로 사료된다. In children, change in lifestyles such as an increase in participation of physical activities has increased the chance of receiving an injury, harming the child and their parents. This study was carried out to give basic information of traumatic injuries to the upper anterior teeth which can be used in prevention of future complications that may arise. From June, 2002 to May, 2003, of the 8,799 children in their primary and mixed dentition visiting Department of Pediatric Dentistry, College of Dentistry, Yonsei University. 955 upper anterior teeth(primary 543, permanent 412) of 487 children(ma1e 316, female 171) with traumatic injures to the upper incisors were studied. The results were as follows: 1. Trauma to the primary teeth prevailed at the age of 1-3 and to the permanent teeth at the age of 7. The male to female ratio was 1.851. 2. Trauma to the upper incisors for both the primary and permanent teeth occurred in the afternoon. Primary teeth were injured most frequently in the home(44.1%) and the permanent teeth outdoors, in the street(l7.5%). 3. Both the primary and permanent teeth were most injured by fall-down injuries(39.8%, 12.9%), and next were collisions(22.2%, 6.0%) :For the primary teeth, high fall, traffic accident, violence and sports are next in order, and for the permanent teeth, violence, sorts, traffic accidents were next. 4. Average number of 1.6 primary teeth and 2.8 permanent teeth were injured with the right central incisor most prevailing. 5. Crown fracture without pulpal exposure and subluxation injures were highest in frequency in both the primary and permanent teeth.

In this paper, we propose the improved watershed algorithm that resolves the oversegmentation problem shown in the previous watershed algorithm and its modifications when the spatial video segmentation is performed. The principal idea of the proposed algorithm is merging the shallow catchment basin whose depth is less than a given threshold into the deeper one during flooding step. In the flooding process, the growth of the existing catchment basins and the extraction of newly flooded ones are accomplished. We present the experimental results using several MPEG test sequences in the last part of the paper. As a consequence, the proposed algorithm shows good segmentation results according to the thresholds applied by adding very small amount of calculations.

정상섭,윤도흠,오성훈,김선호,서창옥,추성실,노준규,김동익,서정호 대한신경외과학회 1988 Journal of Korean neurosurgical society Vol.17 No.6

A Modified irradiation technique utilizing a linear accelerator for radiation surgery within the brain was performed in 4 patients. Three of them had brain tumors and one small arteriovenous malformation in midbrain. A Hitchcock stereotactic apparatus and a 10 MeV linear accelerator have been adapted and special computer programs for dosimetry were obtained and studied experimentally with a phantom model. Stereotactic radiosurgery is a valuable tool in the treatment of inoperable, deep seated intracranial lesions, the major advantage being high efficacy and smoothness of the procedure, as well as short hospitalization times.

골수유핵세포의 경내피세포 및 경기질세포 이행 과정에서 류코트리엔 B_(4) 역할과 활성산소종 억제의 영향

문영철,오수아,유은선,최문영,안지영,성주명 이화여자대학교 의과학연구소 2008 EMJ (Ewha medical journal) Vol.31 No.2

Objectives:Leukotriene B_(4)(LTB4) is lipid mediator derived from membrane phospholipids during the process of inflammation, having many roles(ie;inducer of chemotaxis, the production of nitric oxide, transepithelial migration of neutrophil). The major activities of LTB4 include the recruitment and activation of leukocytes, suggesting that it may involve the process for transendothelial migration of nuclear cells in bone marrow environment. Reactive Oxygen Species (ROS) have a cell signaling roles that are involved in signal transduction cascades of numerous growth factor-, cytokine-, and hormone-mediated pathways, and regulate many biological systems. In this present study, we focused on the role of LTB4 and ROS on transmigration of bone marrow nuclear cells across endothelial or stromal cell monolayer. Methods:MS-5, murine stromal cell line cells, or bEnd.3, murine microvascular cell line cells, were grown to confluence on microporous transwell membrane. Murine marrow cells were placed on top of the prepared transwell membrane. The transwells were then seated in wells containing media and LTB4 with or without pretreatment of N-acetylcysteine(NAC), an oxygen free radical scavenger, or diphenylene iodonium(DPI), an inhibitor of NADPH oxidase-like flavoproteins. Cells that migrated through the stromal or endothelial layer into the wells were assayed for transendothelial migration. Results:The numbers of migrated bone marrow nuclear cells through the bEnd.3 were increased by treatment of LTB4(control, 12.5±0.2%;50nM, 22.7±0.9%;100nM, 44.3±1.4%;200nM, 36.3±0.9%;p<0.05). The numbers of migrated bone marrow nuclear cells through the MS-5 were also increased by treatment of LTB4(control, 11.0±0.9%;50nM, 25.7±0.9%;100nM, 35.8±1.8%;200nM, 32.1±0.9%;p<0.05). However, increasing effect of LTB4 to the transmi-gration of bone marrow nuclear cells through the MS-5 or bEnd.3 were inhibited by pretreatment of NAC or DPI. Conclusion:Through our data, it is suggested that LTB4 could induce the transmigration of bone marrow nuclear cells and ROS might be involved on the transendothelial migration of bone marrow nuclear cells by LTB4. It would be very interesting to test the effects of LTB4 and ROS on stem cell mobilization and homing in the future. 류코트리엔 B_(4)(LTB4)는 세포막 인지질로부터 유래된 염증과정에 관여하는 지방매개체이다1-3). LTB4의 주된 역할은 화학주성의 유도, 활성산소의 생산, 백혈구, 특히, 호중구 및 호산구의 이동에 관여하고 있으며, 내피세포와 백혈구의 부착에 중요한 역할을 하는데, 이러한 LTB4의 역할은 케모카인에 의한 백혈구의 이동과 화학주성과 많은 부분에서 유사한 특성을 가진다4-7). 염증반응과 백혈구 이동과 연관된 LTB4의 역할들은 골수내 세포들의 이동 과정에서 다른 시토카인이나 성장인자 혹은 케모카인의 역할과 유사한 점이 많다. LTB4와 비슷한 작용을 가진 여러 케모카인들이 조혈모세포를 포함한 골수내 세포들의 이동과 연관이 있음이 최근 밝혀짐에 따라, LTB4도 골수내 세포의 이동에 관련이 있을 가능성이 있다8-14). 활성산소종(ROS)은 여러 종류의 성장인자, 시토카인, 혹은 호르몬 등으로 유도된 조혈세포내 신호전달체계에 중요한 역할을 하고, 조혈세포내 여러 생명현상의 조절과 관련이 있다15-18). 특히, 염증세포에서 분비된 시토카인 혹은 케모카인들이 세포내 ROS를 증가시키고, 이때 증가된 ROS는 혈관내피세포 단층의 투과성을 증가시켜 백혈구의 경내피세포 이행을 용이하게 한다19-22). 조혈모세포 이식 후 조혈모세포가 말초혈액에서 골수 내로 자리잡는 귀소나, 골수내 조혈모세포를 혈액으로 나오게 하는 가동화의 과정은 매우 복잡하여, 여러 다양한 기전들이 관련이 있지만, 혈관내피세포 및 기질세포와 골수 조혈세포들과의 유기적인 반응과 골수 조혈세포의 경내피세포 이행이 중요한 역할을 한다23)24). 본 연구에서는 골수유핵세포의 경내피세포 및 경기질세포 이행에 LTB4와 ROS가 어떻게 영향을 미치는지 알아보고자 하였다.
