The silylation of sodium silicate, Water glass, for the preparation of new orqanic matters has been studied through silicic acid from commercial sodium silicate and organic silane. Sodium silicate was acidified by addition of diluted sulfuric acid carefully under prevention of gelation, and prepared silicic acid solution was extracted by tetrahydrofurane. finally trimethylsilylates was prepared by reaction of the silici acid and trimetylchlorosilane. The authers have investigated properties of the silylates through IR, ¹HNMR spectra, X-Ray diffraction, thermal analysis and gel chromatography. And it was clear that the molecular weight of the trimethylpolysiloxane 1000 to 1500, the decomposition temperature 390 to 410℃ and the melting point 80 to 150℃.

목 적 : 한국에서 발생빈도가 높은 암의 하나인 직장암의 치료에 있어 전국의 각 병원 치료방사선과(방사선종양학과)에서 시행하고 있는 치료 형태를 세부 항목별로 파악하여 방사선종양학 전문의 간의 치료원칙의 차이점을 분석하고 이를 바탕으로 향후 Patterns of Care Study를 위한 연구의 기본 자료로 제시하고자 한다. 대상 및 방법 : 경인지역 소재 18개 대학병원 및 방사선종양학과가 있는 병원들의 방사선종양학과 전문의들이 모여 직장암의 방사선치료 원칙 분석을 위한 consensus committee를 구성하고, 회합 및 설문조사를 통하여 각 의사들의 방사선치료 원칙을 파악하기 위한 세부 항목 설정과 이를 토대로 직장암 환자 개개인의 치료 내용을 측정하는 구체적인 항목들을 개발하였다. 이 항목들을 이용하여 직장암의 방사선치료를 담당하고 있는 전국의 방사선종양학과 전문의들을 대상으로 설문조사를 시행한 후 각 전문의들의 의견이 일치하는 부분과 상이한 부분들을 분석하였다. 결 과 : 전문의 별 치료원칙의 측정에 사용된 항목들은 1) 치료대상환자의 선정기준 8개 항목, 2) 수술 전후 병기 및 예후 인자 검사 20개 항목, 3) 수술 및 항암화학요법과의 병용기준 7개 항목, 4) 환자의 setup 및 처치 9개 항목, 5) 모의치료시 조사야 결정 19개 항목, 6) 치료계획 5개 항목, 7) 치료 중 상태 확인 위한 이학적/병리학적 검사 4개 항목, 8) 치료 후 추적 관찰시 검사할 10개 항목 등 총 82개의 항목이 개발되었다. 이 항목들은 전국 각 병원들의 방사선종양학과 전문의를 대상으로 설문조사 되어 치료원칙에 대한 분석이 항목별로 이루어졌다. 설문조사 결과 전국의 각 병원 방사선종양학과에서 시행되고 있는 직장암의 방사선치료 형태는 일정 범위를 유지하고 있으나, 일부 항목에 있어서는 치료자 간 의견차이가 큰 것으로 나타났으며 이들 중 전체 응답자의 50% 이상에서 합의가 되지 못한 항목들은, 1) 치료환자의 선정 기준 중 수술 전 방사선치료 대상, 2) 병기 결정 검사 중 직장내 초음파(EUS, endorectal ultrasound), 흉부 CT, 뼈 스캔 등의 시행 여부, 3) 항암제와의 병용 원칙, 4) 모의치료시 소장 위치 확인을 위한 조영제 사용, 5) 조사야의 경계선 결정, 6) 치료 후 추적 관찰 시 CEA와 대장내시경의 시행여부 등이었다. 결 론 : 이견이 많은 항목들에 대해선는 향후 담당 전문의들을 대상으로 consensus meeting등을 통한 체계적인 분석 및 합의의 도출이 필요한 것으로 보이며, 본 연구에서 밝혀진 각 병원들의 치료 내용을 토대로 향후 표준화된 치료 모델 개발을 위한 Patterns of Care Study가 진행될 예정이다. Purpose : To conduct a nationwide survery on the principles in radiotherapy for rectal cancer, and develop the framework of a database of Korean Patterns of Care. Study. Materials and Methods : A consensus committee was established to develop a tool for measuring the patterns in radiotherapy protocols for rectal cancer. The panel was composed of radiation oncologists from 18 hospitals in Seoul Metropolitan area. The committee developed a survey format to analyze radiation oncologist's treatment principles for rectal cancer. The survey items developed for measuring the treatment principles were composed of 1) 8 eligibility criteria, 2) 20 items for staging work-ups and prognostic factor, 3) 7 items for principles of combined surgery and chemotherapy, 4) 9 patient set-ups, 5) 19 determining radiation fields, 6) 5 radiotherapy treatment plans, 7) 4 physical/laboratory examination to monitor a patient's condition during treatment, and 8) 10 follow-up evaluations. These items were sent to radiation oncologists in charge of gastrointestinal malignancies in all hospitals (48 hospitals) in Korea to which 30 replies were received (63%). Results : Most of the survey items were replied to without no major differences between the repliers, but with the following items only 50% of repliers were in agreement : 1) indications of preoperative radiation, 2) use of endorectal ultrasound, CT scan, and bone scan for staging work-ups, 3) principles of combining chemotherapy with radiotherapy, 4) use of contrast material for small bowel delineation during simulation, 5) determination of field margins, and 6) use of CEA and colonoscopy for follow-up evaluations. Conclusion : The items where considerable disagreement was shown among the radiation oncologists seemed to make no serious difference in the treatment outcome, but a practical and reasonable consensus should be reached by the committee, with logical processes of agreement. These items can be used for a basic database for the Patterns of Care Study, which will survey the practical radiotherapy patterns for rectal cancer in Korea.

An Evaluation of Energy Saving Measures for Ocean Going Vessels

Kim, Yong-Wong,Kang, Dal-Won,Nam, Ki-Chan,Nam, Hyung-Sik Korean Institute of Navigation and Port Research 2015 한국항해항만학회지 Vol.39 No.2

This paper analyzes and evaluates the importance of energy saving measures based on qualitative survey. Through literature review and group interviews with specialists, 4 factors, 13 measures for energy savings, and 4 evaluation criteria were selected to carry out an Analytic Hierarchy Process (AHP) analysis. At the first stage of AHP analysis, the importance of factors was derived, and then the importance of 13 measures. Lastly, the cross examination of 4 factors was carried out in order to evaluate the best possible qualitative considerations. The result revealed that 'choosing the best course weather', is the most important factor with the highest value on applicability and operational complexity criteria. These results may imply that operational considerations are regarded as a main factor to be taken into account when considering appropriate energy saving measures.

We have always attempted to create a standard treatment protocol for patients with gastric cancer. However, many debates still exist regarding gastric cancer treatment. For the past 2 years, at the Annual Congress of the Korean Gastric Cancer Association, we have presented a grand symposium on the "Debates on the strategy for treating gastric cancer". In 2008, four major topics were discussed and voted on after discussion. The four major topics were proximal location treatment for early gastric cancer, management choices for pyloric obstruction with advanced gastric cancer, management of liver metastasis, and reconstruction methods after a distal gastrectomy. The opinions of the audience for six minor topics were expressed by an electronic voting system. In 2009, the four main topics were treatment for submucosal tumor sized around 2 cm, laparoscopic gastrectomy in T2N1 gastric cancer, choices for managing gastric lymphoma, and application of a pylorus preserving procedure for early gastric cancer at the antrum. The opinions of the audience for these six minor topics were expressed by an electronic voting system, as was conducted in 2008. It was good opportunity to identify a point of contact about the debates on managing gastric cancer. The results of these debates and studies will identify the best methods to treat patients with gastric cancer.

Percutaneous endoscopic gastrostomy (PEG) was introduced into clinical practice in 1980 and has become a preferred method of feeding gastrostomy tube placement. Since our first description 1986 in Korea, PEG has supplanted its surgical counterpart in many Korean institutions. During the periods from January 1986 to December 1990, we have managed 102 patients with a PEG. This study reviewed our experience with PEG with respect to the incidence of PEG-related problems and the efficacy of the procedure. 1) Mean age of patients were 43 years(range 15∼78), Primary diagnosis in 102 patients undergoing PEG was head trauma; 63, stoke; 20, CO poisoning; 4, brain tumor; 2, esophageal cancer; 5, cardiac cancer; 6, esophageal poerforation; 1, esophagobronchial fistula; 1. 2) PEG was succesful in 95 patients (93%) and mean operation time was 15 minutes (range 9∼42). Seven patients failed to have a gastrostomy placed for technical reasons including; previous gastrectomy; 2, no transillumination; 2, broken silk suture during procedure; 2, large ventral hernia; 1. 3) The PEG tubes remained well in 88 patients with functioning over 3 months and the longest functioning of PEG tube was 27 months to date. 4) Weight gain was noted in 66 of 88 patients (75%) and mean weight gain was 38%. 5) The incidence of PEG-related complications was 18% and three postoperative death occurred which were related to the patients underlying disease. This author's experience with these 102 patients has led to the conclusion that PEG is safe, easy to perform, and effective means of establishing access for enteral feeding.Key Words: Percutaneous endoscopic gastrostomy, enteral feeding.
