  • Purpose : Radical gastrectomy is main treatment of gastric cancer. But the result is not satisfactory with surgery alone. Most of pattern of failure remain locoregional recurrence. To improve 5 year survival postoperative chemotherapy with or without radiotherapy has been used. We analyzed patients with stage III and IV stomach cancer who had radical operation and received postoperative radiation therapy combined with or without chemotherapy retrospectively. Material and Method : From March 1985 to June 1993, 68 patients treated with curative resection and received postoperative adiuvant radiotherapy with 36Gy or more were evaluated. Median age was 60 years(range 28-66 yrs) . Patients were followed from 3 to 133 months with median follow up of 48 months. Thirty seven patients had non signet ring adenocarcinoma, 29 signet ring cell, 2 other cell. Patients with stage IIIA, IIIB, IV disease were 19, 25 and 24 respectively Chemotherapy was given to all patients except two. Results : Five-year overall survival and disease-free survival rate were 36.6% and 33.6%, respectively. Prognostic factor affecting survival were assessed. High ratio of jnvolved/dissected Iymph node, signet ring histology showed Poor Prognosis with statistical significance. Presence of residual tumor after surgery, stageIV. split course of radiation therapy, age, number of involved Iymph node, number of Iymph node dissection and grade of tumor affected survival without statistical significance, Type of chemotherapy did not affect survival. Recurrence was documented in 34 patients. High recurrence was seen in omentum and peritoneum with 23.5%, and remnant stomach, anastomosis site, A-loop and I-loop had also high recurrence with 13.2%. In field locoregional recurrence was 20.7% and total distant metastases were 39.7%. Total intraabdominal failure was 47.1% and extraabdominal failure was 13.2%. Treatment toxicity was considered to be acceptable. 22.1% of patients had grade 3 and only 1 patient had grade 4 leukopenia. Six Patients(8.8%) had weigh loss more than 10%. Conclusion : Treatment toxicity was acceptable with combined treatment with chemotherapy and radiotherapy. Locoregional recurrence was relatively low compared to distant failure with addition of irradiation. Peritoneal and omental seeding was high Five-rear surival was increased with combined modality. Radiation may eradicate minimal residual disease and improve survival, To evaluate role of radiation Prospective randomized study employing chemotherapy alone and chemotherapy plus radiation is necessary. Futhermore to reduce intraabdominal failure, role of intraabdominal chemotherapy in addition to combined chemotherapy plus radiation has to be explored.

  • There are exposed Samrangjin Tuff and intracaldera intrusions, of which rhyolitic rocks emplaced as postcollapsed central and ring intrusions within the Samrangjin caldera, and fine-grained granodiorite and biotite granite as regional tectonic intrusions nearby. The Samrangjin Tuff and the rhyolitic rocks are of a single Samrangjin magmatic system. Flow-banded rhyolite among rhyolitic rocks was emplaced in the outer part of the ring intrusions, rhyodacite in the inner part of the eastern ring, and porphyritic dacite and dacite porphyry in the inner part of the northwestern ring. Totally the Samrangjin Tuff and the rhyolitic rocks range from rhyolite to dacite in chemical composition. The Rb-Sr isotopic data of the Samrangjin Tuff and the rhyolitic rocks yield an age of $80.8{\pm}1.5(2{\sigma})$ Ma with the initial $^{87}Sr/^{86}Sr$ ratio of $0.70521{\pm}0.00010(2{\sigma})$. The continuous compositional zonations generally define a large stratified magma system in the postcollapse magma chamber. The Sr isotopic data suggest that the compositional zonations might have resulted from the fractional crystallization of a parental dacitic magma.

  • OBJECTIVES: This study was performed to find out static two-point discrimination (TPD) in fingertips. METHODS: This was a cross-section, measure study of static two-point discrimination involving healthy young adults. Measure was completed by 48 college students in Andong Science College from June 1 to 12, 2004. The minimal distance at which two-points could be discriminated was measured from thumb to little finger. RESULTS: For dermatomal regions of the fingertip, mean values ranged from 3.3mm to 4.9mm (thumb 3.6mm, index finger 3.3mm, middle finger 3.8mm, ring finger 4.2mm, and little finger 4.7mm in the left hand; thumb 3.7mm, index 3.5mm, middle 4.0mm, ring 4.3mm, and little 4.9mm in the right hand). A significant difference in discrimination ability was found between men and women, 3.5mm for women showed a greater sensitivity than 4.1mm for men in the left middle fingertip(p=0.0109), also 3.9mm for women showed a greater accuracy than 4.5mm for men in the left ring fingertip(p=0.0388). In the right index fingertip, women (3.1mm) have a narrow distance than men (3.6mm)(p=0.0329). The minimal distance of TPD was found a significant difference between 20 and 30 years in age. 4mm for 30 years showed a greater distance than 3.5mm for 20 years in the left thumb fingertip(p=0.0354), also, 3.8mm for 30 years showed a greater distance than 3.2mm for 20 years in the left index fingertip(p=0.0174), and 4.3mm for 30 years showed a greater distance than 3.7mm for 20 years in the left middle fingertip(p=0.0444). In the right index fingertip, 20 years (3.2mm) had also a narrow distance than 30 years (4.1mm)(p=0.0020), 20 years (3.9mm) showed a narrow distance than 30 years (4.6mm) in the right middle fingertip(p=0.0124), and 20 years (4.1mm) showed a greater sensitivity than 30 years (5.0mm) in the right ring fingertip(p=0.0070). CONCLUSIONS: Our results suggest that distance of TPD in the both index fingertips for 20 years women was significantly narrowed.

  • Cheolwon Group in the Cheolwon Basin, which lies northwest of the Gyeonggi massif, has been correlated to the Yucheon Group in the Gyeongsang Basin, but its ages and volcanic times are defined to be considerately earlier than the other one. In this study, SHRIMP zircon U-Pb ages were determined from the igneous rocks in the Cheolwon Basin. The mean ages from zircons are $115.0{\pm}1.1Ma$ in rhyolite, and $111.24{\pm}0.85Ma$ and $109.1{\pm}1.1Ma$ in granite porphyry. The minimum age is 113 Ma in the Jijangbong Tuff. Such age in the rhyolite define the intrusion time of ring dykes, suggesting a caldera collapse following eruption of the Dongmakgol Tuff. Such age in the Jijangbong Tuff represent latest volcanism as postcaldera in the basin. The volcanic rocks in the basin were erupted during late Aptian, and are correlated to the Sindong Group in the Gyeongsang Basin. The plutonism in the basin occurred during $111.24{\pm}0.85Ma{\sim}109.1{\pm}1.1Ma$, following the volcanism. The age distribution of the analyzed zircons in the Jijangbong Tuff indicates the presence of foreign zircons derived from protoliths, regarding a wide span of zircon ages from Cretaceous to Jurassic, Triassic, early and late Protozoic, and Archean. The Archean age suggests the possible presence of the Archean protoliths with such age, which have not been exposed on the surface. The age distribution with wide span suggests that its vent is located in an area that several strata with different ages piled up and intercepted with some intrusives.

  • This case presents application of bioadhesive for inguinal hernia repair of Jeju native pigs. An inguinal hernia was diagnosed in Jeju native pigs, respectively, 3 days of age and 30 days of age, by physical and radiographic examination. Inguinal herniorrhaphy was performed under sedation with azaperone. After excision of scrotal sac, gently separated testis and intestinal loops. Herniated testis was isolated from scrotal sac and intestinal loops were replaced in the abdominal cavity. The external inguinal ring surface and skin closed using the technique of tissue adhesive. The patients were recovered without post-operative complications. This result considered that bioadhesive application could be a simple method to reduction of scrotal hernia without post-treatment like removal of sutures.

  • Based on pathological findings, 5 German shepherds, revealed a mean age of 7.6 years, showing no clinical signs were diagnosed as tracheopathia osteochondroplastica(TOC). Grossly, multiple small-sizecd nodules, appeared as cobble-stones, on the cartilage rings situated in the anterior trachea and the mucosal surface of the epiglottis were showed. Numerous tiny nodules were scattered on the pleural surface of the lung. The vascular walls of the heart were irregular and coarse apearance with calcification. Histopathologically, nodules in the trachea represented an irregular expansion of the underlying tracheal ring with protrusion into the submucosa and consisted of proliferated and calcified cartilage and bone with marrow spaces containing numbers of hematopoietic cells. Pulmonary calcinosis and calcification of the vascular walls of the heart were observed. Our observations suggested that TOC arises form eccondroses and exostoses of the tracheal cartilage rings.

  • Pulmonary sequestration occurs when some disturbance produces a cystic mass of nonfunctioning lung tissue which lacks normal communication with the tracheobronchial tree. Between 1971 and 1985, pulmonary sequestration was diagnosed in 11 patients, ranging age from 3 to 29 years. All sequestration were intralobar type. Definitive diagnosis can only be obtained by aortography and/or surgical exploration in 10 cases. The other one was confirmed by pathologic examination postoperatively. The presenting complaints were mostly recurrent local pulmonary infection, but in 2 cases mediastinal mass with respiratory symptoms was presented, and cardiac murmur was only finding in one case. Preoperative diagnostic procedure revealed 3 associated anomalies which were funnel chest, right aortic arch, and pulmonic stenosis with vascular ring. Operative treatment for sequestration was lobectomy in 10 cases, and a segmentectomy in one. There was no operative mortality, but 3 complications [empyema, B-P fistula, post-op bleeding] which were controlled by subsequent operations or conservative measure. Aortography is strongly advocated not only for its diagnostic value, but for its preoperative localization of the aberrant vessels that are the major concern to the surgeon.

  • Fiber-reinforced self-compacting concrete (FRSCC) is a new type of concrete mix that can mitigate two opposing weaknesses: poor workability in fiber-reinforced concrete and cracking resistance in plain SCC concrete. This study focused on early-age cracking of FRSCC due to restrained drying shrinkage, one of the most common causes of cracking. In order to investigate the effect of fiber on shrinkage cracking of FRSCC, ring shrinkage tests were performed for polypropylene and steel fiber-reinforced SCC. In addition, finite element analyses for those specimens were carried out considering drying shrinkage based on moisture diffusion, creep, cracking resistance of concrete, and the effect of fiber. The analysis results were verified via a comparison between the measured and calculated crack width. From the test and analysis results, the effectiveness of fiber with respect to reducing cracking was confirmed and some salient features on the shrinkage cracking of FRSCC were obtained.

  • The objectives of this study were to identify the species of a wooden container for written prayers, Sotong, from Guryongsa Temple in Wonju, which is currently stored in the Museum of Woljeongsa, and to date it using wiggle matching of radiocarbon dates. It was made exclusively of basswood, Tilia spp. Wiggle matching the radiocarbon dates of three rings resulted in A.D. 1670 to 1691 (${\pm}2{\sigma}$) for the outermost ring. This interval suggested the age of 'Guryongsa Sotong' as the late $17^{th}$ or early $18^{th}$ century, which became a first date on 'Sotong' in Korea.
