According to the increase of the number of dental clinics and the level of the patient's recognition about oral health care, the need for effective clinical management to provide proper oral health care service to the patients has arisen. Many patients has selected the dental clinics based on self estimation or other recommendation. Therefore the main reasons for selecting the dental clinic by the patients needed to analyze, So we conducted the survey which prepared questionnaire were provided to 700 subjects and collected data related to the factors for patients to select the dental clinics. The results were as follows : 1. In the view of access, the place easy of access and parking capacity was important to the degree of 43.0% and 30.8%, respectively. 2. In relation to the dentist, the quality of treatment and the trust was important to the degree of 80.7% and 71.3%, respectively. 3. Modern clinical facility was occupied 65.5% in the basic environment factors. 4. In the basic factors, kindness and cleanliness was 76.6% and 76.7%, respectively, and it showed that these factors were more important than the number of the clinicians and comfort of the waiting room. 5. In relation to the satisfaction of treatment, cheaper treatment cost, decreased waiting tine, the variety of treatment tine and various payment method were important to the degree of 51.8%, 48.4%, 42.8% and 39% in order.

Each and everything named fashion together with clothes were limited in the boundary of women and men's wear has been slow and narrow in changing speed compared to women's, even there are some differences in accordance time. But maintaining the basic features, men's wear in the latter 20th century has undergone diverse change in the part of materials such as various synthetic fiber, glass, metal, artificial leather and the see-through fabric able to seeing the body wearing the clothes. Therefore, the aim and definition of this study is to present the systematic framework giving help to develop men's wear design newer and more various by considering moulding of materials which existing men's wear could not show up and by grasping material trend of men's clothes in 1990s. The results of the study were summarized as follows : (1) Material containing lustering is categorized as Velvet, Silk, Lustering materials by synthetic fiber and Lustering materials by additional substance. The Velvet generally acknowledged having something to feel womanly image shows the bisexual character coexisting feature of men and women after grafting with men's fashion. The Silk was endowed the role as means of pleasure to express beyond boundary of sex breaking the existing consciousness which men should wear male clothes, not considering differences between men and women. The lustering made by synthetic fiber expressed modern sensitivity aesthetically to the suit. The lustering materials made by additional substance is seen mixed masculine character with womanly character. (2) See-through materials are acknowledged as decadence beauty caused by expanding subjective awareness in beauty. (3) Materials by the sorts of Net is categorized as Lace, Knit The Lace expression seemed to emphases the human liberation of men and women and the humanity from liberation of subjecthood. The Knit can be felt both woman's image and man's image as bisexual image, not raising only one side sex. (4) Elastic materials offered the opportunity to approve exposure in a time when exposure of men's body was not granted ethically. (5) Leather was shown as indication of social status and inferiority and expression of collective resistance against sexual stagnation of men and women.

위궤양에 의한 담관-위 누공은 매우 드문 질환이며 소화성 궤양에 의한 담관 누공의 경우 대부분 내과적 치료가 우선적으로 시행된다. 저자들은 내과적 치료에 호전되지 않는 궤양성 담관-위 누공을 외과적 절제술을 시행하여 완치하였기에 문헌고찰과 함께 보고하는 바이다. 64세 남자 환자가 15년 동안 지속된 식사 후 복통과 우상복부 동통을 주소로 내원하였다. 위 내시경 소견상 위전정부, 소만곡 후벽에 담즙이 역류하는 궤양저가 관찰되었으며 상복부위장관 촬영상 위전정부와 총수담관이 교통하는 소견이 있었으나 전산화복부단층 소견상 담석의 증거는 없었다. 담관-위누공 의심하에 체간미주신경절단술, 유문절제술, 담낭절제술, 총수담관절제술 후 환자는 퇴원하였다. Choledochogastric fistula complicated from gastric ulcer is very rare. Most of the internal biliary fistula by peptic ulcer were successfully managed with conservative treatment. Authors reported successful surgical resection of choledochogastric fistula caused by gastric ulcer. A (54-year old man visited our hospital complaining of postprandial abdominal pain and right upper quadrant pain for 15 years. He has a history of peptic ulcer medication for four years, recently. A gastrofiberscopy revealed ulceration on the posterior wall along the lesser curvature, gastric antrum with bile reflux from ulcer base, and histopathology of the biopsy specimen revealed an ulcer without evidence of malignancy. Barium upper gastrointestinal study showed fistula between stomach and common bile duct. In abdominal CT, there was a pneumobilia with dilated intrahepatic duct without common bile duct dilatation. After the diagnosis of choledochogastric fistula, we performed truncal vagotomy with antrectomy and cholecystectomy with resection of extrahepatic bile duct. The patient has remained well since his discharge from hospital.

Selective COX (cyclooxygenase)-2 inhibitors including celecoxib have been shown to induce apoptosis and cell cycle changes in various tumor cells. New inhibitors are recently being developed as chemomodulating agents. We evaluated celecoxib and screened 150 synthetic compounds for anti-proliferative activities in vitro. Effects of celecoxib on COX activity, cell growth, cell cycle distribution, and apoptosis induction were determined in A549 COX-2 overexpressing human non-small cell lung cancer (NSCLC) cells. The COX inhibition of celecoxib increased with concentration up to 82% at 1μM after 24 hr exposure. Forty μM and 50μM of celecoxib induce G_1 arrest, and TUNEL-positive apoptotic cells, respectively. Among 150 compounds, several compounds were selected for having greater COX-2 inhibitory activity and higher selectivity than celecoxib with growth inhibitory activity. Celecoxib showed concentration-dependent COX inhibitory activity, and ability to induce cell cycle arrest and apoptosis in human NSCLC cells in vitro. Among synthetic analogues screened, several compounds showed promising in vitro activity as COX-2 inhibitory anticancer agents, which warrant further evaluation in vitro and in vivo.

한반도에 분포하는 참회나무, 회나무, 나래회나무의 영양기관에서의 유효 식별 형질을 확인하기 위하여 166점의 표본 조사를 통해 단변량 분석을 실시하였다. 3종을 대상으로 4개의 정량형질(잎의 길이, 잎의 너비, 엽두의 길이, 엽병의 길이)을 측정하였다. 형질 분석 결과 3종에 대한 잎의 형질은 종간 차이를 보이지 않아 종간 식별에 도움이 되지는 않았다. 따라서 본 분류군에 있어서 잎의 형질만을 가지고 종을 식별하는 것은 타당하지 않고 반드시 꽃이나 열매가 있어야 이 분류군을 인식할 수 있다고 판단된다. 분포에 있어서 회나무는 강원도에서 평안도에 걸쳐 분포하고, 참회나무는 백두대간을 중심으로 한반도 북부까지 분포하며 나래회나무는 한반도 남쪽지역을 중심으로 분포하는 양상으로 보여 분류군 간에 다소 차이가 있지만 대부분 강원도를 중심으로 분포가 겹친다. Leaves of 166 specimens were sampled to investigate patterns of interspecific variation and to evaluate recognition of Euonymus planipes, E. oxyphyllus. and E. macropterus using four leaf characters (length, width, apex length, and petiole length). This study suggested that these leaf characters were not useful to identify these taxa. Therefore, it is only possible to identify these closely related taxa based on flower and fruit characters unlike other horticulturists' view.
