A 10-year-old spayed female Pekinese dog was referred to veterinary medical teaching hospital of Chonbuk National University with signs of dysuria, abdominal distension, and hematuria. Abdominal radiography revealed a large oval soft tissue mass in cranial abdomen, which was a fluid filled cyst containing a round mass by ultrasonography. Exploratory laparatomy found a 4 cm cyst containing reddish brown fluid and a 1.5 cm small round mass attached to the wall. Cytological impression of the imprint smears of the resected mass were highly malignant adenocarcinoma, which was confirmed by histopathology of the mass and the cyst. After the surgery the patient recovered uneventfully and discharged. The tumor recurred about one year after surgery, and second surgery performed at the owner's request. However the tumor recurred in two months with metastatic disease in the lung and the dog survived three more months after surgery.

현대사회에서 화재에 의한 물적 피해는 물론 인적피해가 현저하게 증가하고 있으며 희생자의 사망원인이 종래에는 화재시 발생한 열에 의한 화상을 중심으로 하는 소사였지만, 최근에는 화염보다 독성가스로 인하여 사망하는 경우가 많아졌고, 희생자는 거의 화상을 확인할 수 없거나 화상자이더라도 혈액 중에서 일산화탄소를 중심으로 한 유독가스가 확인되기 때문에 이들 유독가스의 흡입으로 인하여 행동불능상태 이후 열의 영향으로 사망한 것으로 추정되는 사례가 증가하는 추세이다. 따라서 대규모 건축물에 있어서는 화재발생시 유독가스가 건물 전체로 연소 확대되는 것을 방지하기 위하여 넓은 면적을 일정한 면적으로 구획하거나 계단실 등과 다른 부분 또는 층별 등으로 구획하고 있으며, 국내의 방화구획은 크게 다른 층으로 화재전파를 막기 위한 층간 방화구획, 연소면적을 제한하기 위한 면적별 방화구획, 다른 용도로 인한 화재 위험성 감소를 위해 용도별 방화구획으로 3가지를 법에서 채택하고 있다. 방화구획은 방화문 또는 자동방화셔터를 이용하거나, 내부구조의 바닥, 벽, 각종 방화문으로 구획할 것을 정하고 있다.(피난방화규칙 제14조) 본 연구에서는 철제방화셔터 대체용으로 직물방화셔터용의 실리카 소재를 이용하여 제직한 직물에 내열/차연 기능성 코팅의 공정 조건을 변화하여 최종 방화시험을 거치기 전 내열성 테스트중 하나인 불꽃열 통과량 실험을 실행하여 방화 직물의 내열성을 비교 분석하였다. 이러한 결과를 토대로 본 연구는 고내열/차연성 방화 제품 기술을 개발하는데 필요한 연구를 수행하는데 목적이 있다.

Recently, the W3C has developed the HTML 5 standard to provide various multimedia services as well as a web based streaming. HTML5 based web browsers with the built-in video codecs can be used directly for streaming services, though previous web browsers should contain playback plug-in for streaming services. In addition, an adaptive streaming technology using HTTP/TCP has been standardized, since an Internet firewall does not support RTP/UDP streaming protocol but HTTP/TCP streaming protocol. In this paper, we propose the service migration mechanism among various devices in the HTML5-based adaptive HTTP streaming environments. The proposed algorithm and architecture were modeled for migrating media flows, media flow control, and session control and implemented using JavaScript. Finally, we showed that the proposed mechanism was effective to migrate HTTP streaming service among various devices by performing several experiments.

This research has been carried out to examine the effects of quality promoting agents on global quality and epidermal changes of Chamaecereus silvestrii 'Hee-mang' for quality maintenance of the transportation. D-sorbitol than D-mannitol treatment was effective in a lower reduction of fresh weight in C. silvestrii transportations. Application of diniconazole 200 ppm suppressed growth of C. silvestrii. However, it enabled the possibility of long-tenn plant transportation (up to 50 days) and color formation was also effective. As for epidermis structure of C. silvestrii, hypodermis development was lower compared to Gymnocalycium friedrichii and its long-term transportation became poor quality due to single layered, thin cell wall. Application of diniconazole 200 ppm + D-mannitol 10,000 ppm showed higher growth suppressing effects and diniconazole 200 ppm + wax treatment showed better color formation suitable for quality maintenance and storage purposes for C. silvestrii.

When the temperature of a flange in a refrigerator is reduced to the dew point, condensation is generated on the flange. Generally, hot lines, having a temperature of $35^{\circ}C$, are located near the flange to increase its surface temperature above the dew point. Hot lines are installed in close contact with the flange in order to increase the heat transfer from the hot lines to the flange surface. Through this work, the effects of the hot line shape and installation conditions, including a gap between the hot line and flange, and the function of a spacer in the inner case of the refrigerator were investigated. Additionally, an optimal shape of the inner case for easy assembling is proposed considering the contact between the hot line and flange.

Surgical anterior ventricular endocardial restoration (SAVER) is a technique that improves hemodynamic status by excluding akinetic or dyskinetic portions of the left ventricle, restores the ventricle to normal elliptical shape and reduces ventricular wall tension to normal level in patients with acute anterior wall myocardial infarction that accompanies aneurysm. We performed redo-SAVER procedure in a 40-year old man with remodeled dilated ventricle who had already underwent LV aneurysmectomy 12 years earlier, and the results were satisfactory.

In the Chosun Dynasty (1392-1910), the walls and chimneys of palaces, temples, and the houses of the upper-class show various characteristics of decorative design patterns. This study investigated ceramic bricks and roof tiles, which is one aspect of environmental design studies. This study aimed to provide a typology ot traditional Korean design of bricks and roof tiles used in walls and chimneys, and to show the design characteristics. This study collected 685 designs of bricks and roof tiles, and divided them into 18 categories and 5 types of design patterns based on object figures, architectural styles, materials, and decorative methods. In conclusion, there were differences and similarities among the design patterns. In general, the palaces mostly used red, gray, and black bricks that had more detailed designs presenting auspicious signs or exorcism. But, temples and the houses usually used (black) roof tiles horizontally configured with the edges overlapping to decorate as wall as to strengthen their structure.

Consideration on the explosion resistant design of infrastructure has increased in the recent years. The explosion load is caused by gas explosion or bomb blast. In this study an analytical model is developed, whereby the tunnel structure is divided in several elements that are schematized as single degree of freedom mass-spring-dashpot systems on gas explosion. Using this simple model a sensitivity analysis has been carried out on tunnel structure design parameters such as explosive peak pressure, duration of the load, thickness of structure, burial depth. Finite element method was used to investigate the dynamic response and plastic zone of a tunnel under gas explosion. And it was found from the comparison of the analysis results that there are slight differences in the response of the intermediate wall between the single degree of freedom mass-spring-dashpot model and FEM.

This study examined the composition and spatial characteristics of the Illinois Institute of Technology (1939-1959) campus by Mies van der Rohe. Studies of the Mies' architecture has been focused mostly on "universal space", structural rationality for a single building. Therefore, it is interesting to study an IIT campus through which Mies composed public space dealing with several buildings together. To determine the relationships with his previous works and the design intentions for IIT campus, this paper studied his preliminary sketches, perspective drawings etc.. By doing so, the paper presents the following conclusions. First, Mies composed the IIT campus with simple linear buildings as walls to create the "flowing space" through the campus. Secondly, the IIT campus could become the "neutral frame" integrating the campus with urban space. Third, Mies also created an open, continuous public space in the center of the campus that allows protective, quiet seclusion for the students.

For screening of the compounds exhibiting antimicrobial activities against the D-alanyl-D-alanine of Gram positive bacteria, approximately 2,500 actinomycetes isolated from soil were examined far antimicrobial activity. In consequence, we recently isolated the Streptomyces sp. G91353 strain produced an active compound, A91353, that inhibits the growth of Gram positive bacteria. A91353 was identified as N-acetyl-phenylalanine by various spectroscopic methods. The minimum inhibitory concentration (MIC) values of N-acetyl-phenylalanine on Gram positive bacteria such as Streptococcus pyogenes 308A, Streptococcus pyogenes 77A were determined as $50{\mu}g/ml$, respectively, but did not effect on Gram negative strains. These results indicate that N-acetyl-phenylalanine have an antimicrobial activity, which may be caused by the disturbance of D-alanyl-D-alanine synthesis.
