  • Purpose: The aim of the study was to obtain data on the anatomic and histologic distributions, the clinical features, and the treatment results for patients with primary gastric non-Hodgkin's lymphoma. Materials and Methods: One hundred thirty-two patients who were treated at 8 university hospitals and 2 general hospitals between January 1991 and December 2000 were enrolled to evaluate clinico-pathologic features. Results: The lower one-third of the stomach was the most frequent site ($42\%$), and the most frequent chief complaint was epigastric pain ($54\%$). Gastric resection was performed in 114 cases. Pathologic findings of preoperative endoscopic biopsy specimens from the 114 patients that underwent surgery were a gastric lymphoma in 94 cases ($82\%$), a carcinoma in 15 cases ($13\%$), an ulcer in 4 cases ($4\%$), and a gastrointestinal stromal tumor in 1 case ($1\%$). The stage distributions by Musshoff's criteria were 71 cases ($54\%$) of stage IE, 36 cases ($27\%$) of stage $II_{1}E$, 8 cases ($6\%$) of stage $II_{2}E$, 2 cases ($2\%$) of stage IIIE, and 15 cases ($11\%$) of stage IVE. Histologic gradings by the Working Formulation in were 31 cases ($23\%$) of low grade, 96 cases ($73\%$) of intermediate grade, and 5 cases ($4\%$) of high grade. Chemotherapy-related complications occurred in 25 cases ($22\%$) while operation-related complications occurred in 6 cases ($5\%$). Seventeen patients ($13\%$) only underwent surgery, 19 ($14\%$) had chemotherapy (CTx) and/or radiotherapy (RTx) only, and 96 patients ($73\%$) received surgery and CTx and/or RTx. No substantial differences in survival were found in relation to the different histologic grades and different treatments. The five-year survival was $85\%$ in stage I or II and $47\%$ in stage III or IV (P=0.0000). Conclusion: Pathologic stage appears to be the single most important prognostic indicator. Survival differences according to treatment modalities were not statistically significant. However, the low number of patients treated with various approaches over a long period precludes a firm conclusion.

  • Hemophilia, the most common of the inherited bleeding disorder, is the result of a deficiency of clotting factor. Since bleeding after dental treatment may cause severe or even fatal complications, people with hemophilia must be given special dental care. We report on the diagnosis and treatment of a 9-year-old boy having severe hemophilia visited our department with the chief complaints of pus discharge on the left lower molar region. In the clinical and radiographic examination, periapical abscess and dental caries were diagnosed. Considering complexity of the treatment and complication in the coagulation, it was decided to carry on the treatment under general anesthesia. Clotting factor IX concentrates were intended to provide 50-70% plasma level. Pulpectomy, resin restoration and Stainless steel crown were given under general anesthesia. Several teeth were extracted and the sockets were packed with Surgicel$^{(R)}$ (Oxidized Regenerated Cellulose, Johnson and Johnson Co. Neuchatel, Switzerland) under general anesthesia. Transpalatal arch and lingual arch were given for maintaining the extracted space before discharged. For people with severe hemophilia, factor replacement is necessary before scaling, surgery or regional block injections. Therefore, if several extractions are needed, dental care under general anesthesia would be effective and efficient management.

  • Oysters are rich in nutrients with good flavor, and disease prevention is required in both the East and the West for high-quality seafood. The best way to store and transport mass-produced oysters is using dry techniques. Using both hot and frozen drying technologies to obtain a perfectly dried oyster often destroys much of the flavor and nutrients found with the oyster meat. This study uses a low temperature vacuum drying technology to investigate the final weight ratio of wild and farmed dried oysters. Additionally, the heat transfer characteristics of steamed oysters are discussed in this paper.

  • Neurilemmoma is a benign encapsulated nerve sheath tumor originated from peripheral nerve. Previously its preoperative diagnosis had mainly depended on the history, physical examination, electrodiagnostic test, ultrasonography, bone scan. But only with these diagnostic modalities, exact preoperative diagnosis was nearly impossible. Therefore operation was performed under the impression of lipoma or just simple soft tissue tumor. Recently, the advent of magnetic resonance imaging(MRI) has made it easier to diagnose neurilemoma before surgery. MRI also helps to determine the extent of lesion and operative procedures. We performed marginal excision in 24 cases, evaluated those cases with respect to the sex, age, location, chief complaint, duration of illness, preoperative diagnosis, involved nerve, imaging studies, size of mass, complication, duration of follow-up and report with review of the literature.

  • 강원도 홍천일대의 지역은 경기육괴의 편마암이 주암종으로 이루어진 지역으로 대규모의 홍천단층이 지나고 있다. 과거 이 단층대 부근에서 건설된 도로건설시에 발생된 많은 절토사면의 붕괴를 통해 그 원인 파악 및 차후 고려해야 할 사항을 파악하는 것이 매우 중요한 과제 중에 하나이다. 본 논문은 붕괴를 토대로 붕괴의 원인 및 대책방안을 파악하고자 한다. 홍천일대의 사면붕괴를 유발시키는 원인으로는 크게 두 가지 지질구조적인 요인을 들 수 있는데 하나는 사면방향으로 발달하는 편마암내에 발달하는 엽리면을 따라 붕괴가 발생되는 사례가 있고 둘째는 단층파쇄대 및 단층대를 따라 붕괴가 발생되는 원인으로 대별할 수 있다. 두 번째의 요인은 비교적 규모가 큰 사면붕괴를 유발하게 되고 막대한 복구비용이 수반되는 결과를 초래하게 된다. 이러한 단층의 수반에 의해 발생되는 절토사면은 대책방안으로 사면경사완화 방안, 앵커 및 억지말뚝과 같은 보강방법에 의해 안정화를 시키는 사례가 주를 이루었으며 차후 이 일대의 건설공사시에는 단층대의 방향 및 규모에 대한 조사를 세밀히 이루어져야 할 것이다.

  • Two patients, sought treatment for chief complaints of protruding frontal tooth and desired treatment to reduce the prominance of lips, were diagnosed as bimaxillary protrusion via clinical and cephalometric analysis. The authors corrected them by combined surgical and orthodonic treatment. As pre-surgical survey, paper and cast surgery were performed and wafer and resin sprint were constructed. We performed anterior maxillary and mandibular osteotomies in first premolar site to retract the maxillary and mandibular dentoalveolar segment in order to ; 1) decrease prominance of upper and lower lips. 2) create proper lower incisor intrusion. By use of intrtamaxillary fixation, prompt oral intake was possible. We made good result of esthetic improvement and there was no evidence of relapse and any complication.

  • While the United States and Japan have non-government film rating system, Korea and France are still maintaining governmental control process. But the restrict showing rate in Korea does possibly violate the Constitution with no theatre for the movies of that rate right now. No other visual media including broadcasting have any outer classification process before their showing. So we need to improve our system by replacing it with non-governmental system. To establish independent non-government rating system, first of all, the major companies of film industry should get together to set up Korean Classification and Rating Association, to support the Film Rating Board. The most important thing is that the board operates independently. Government can support art cinemas financially with rating fee. Juvenile protection groups have to keep watch on the process of the board going fairly as well. The chief obstacle for non-governmental rating system is the fact that major companies don't want to get it. But continuing efforts to find any rational way is worthy enough.

  • The paper investigates the determinants of firm's standardization activity in the Korean manufacturing industry. Standardization variables as dependent ones are standardization management at the firm level, accreditation activity, domestic standards utilization, and international standards utilization. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, networks, and firm's organization characteristics. We estimated the logistic regression model, using the data from 636 Korean manufacturing firms. The empirical findings are as follows. First, R&D intensity doesn't have any influence on standardization activities, except the utilization of international standards. Second, patent application has a positive effect on standardization management at the firm level and accreditation activity, respectively. Third, the inverse U-shape hypothesis relating firm size is accepted for standardization management and accreditation, respectively. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.

  • The paper investigates the determinants of firm's standardization activity in the Korean service industry. Standardization variables as dependent ones are standardization management at the firm level, domestic standardization activity, and international standardization activity. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, network, and firm's organization characteristics. We estimated the logistic regression model, using the data from 102 Korean service firms. The empirical findings are as follows. First, R&D intensity has a positive effect on international standardization activity, but not on the standardization management at the firm level and domestic standardization activity. Second, patent application has a negative effect on the standardization management at the firm level. Third, firm size doesn't have any influence on firms' standardization activities in the service sector. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.
