  • Background: The aim of this study was to investigate clinicopathologic features of type 3 gastric neuroendocrine neoplasm (NEN) by treatment modality. Methods: The Korean Society of Gastrointestinal Cancer conducted the Korean Gastroenteropancreatic Neuroendocrine Tumor Registry, a retrospective registry database of gastroenteropancreatic neuroendocrine tumors from 16 hospitals in Korea. The normal serum gastrin level range was defined as <100 pg/mL, and gastric NEN patients with normal gastrin level were selected for analysis. Results: Among 358 patients with gastric NEN, 21 (5.9%) patients were classified with type 3 gastric NEN. The median age was 53 years (range 30-74). According to the WHO 2010 classification, 13 (61.9%) patients had grade 1, and 8 (38.1%) patients had grade 2 or 3. Endoscopic treatment was performed in 14 (66.7%) patients, and surgery was performed in 7 (33.3%) patients. The tumor size was smaller in the endoscopic treatment group than in the surgery group (0.6 cm vs 1.3 cm, p=0.006). After treatment, there was one recurrence in the surgery group. Conclusion: In small size Type 3 gastric NEN, endoscopic treatment was associated with a good prognosis, compared to surgery. Thus, endoscopic treatment can be used an alternative modality in selected cases of type 3 gastric NEN.

  • A knowledge of the wide ranges in shape of liver is important in the interpretation of hepatic scintigraphy as some variants may be easily confused with pathological abnormalities. In this study, the variations in shape in 250 cases of normal liver obtained by scintiphoto were categorized into 9 types by means of the arbitrary standard for classification. Following were the results; 1) Among 250 normal cases, type 5 was 118(47.2%) with the highest prevalence and type 3 was 2 (0.8%) with the lowest. 2) A high incidence of obesity was noted in type 1, type 4 and type 8. That of ideal weight was noted in type 2, type 5 type 6 and type 9. 3) A high ratio of cardiac impression in scintiphoto was noted in type 4, type 7 and type 8. That of square left lobe was noted in type 2, type 6 and type 9. Finally that of tailed left lobe was in type 4, type 7 and type 8.

  • Purpose: Pilon fracture is caused by high energy and axial compression forces, and it is often associated with severe comminution and soft tissue injury. Recently, limited internal fixation of this fracture may avoid the soft tissue complications associated with formal open reduction and internal fixation and avoid incongruity of joint margin associated with conservative treatment. We have treated Ovadia and Beals type II or III pilon fracture with limited internal fixation and the results were satisfactory. Materials and Methods: We analyzed 15 cases of Ovadia and Beals type II or III fractures who were treated by limited internal fixation(K-wire or screw fixation) from January 1995 to December 2000. The average follow up period was 20 months(range, 12 to 38 months). According to the Ovadia and Beals classification, seven cases were type II, and eight cases were type III. Radiographic results were assessed by Ovadia and Beals criteria. We also assessed the functional results by Mast and Teipner criteria. Results: Radiographic results showed good in 67% and fair in 33% of cases. Clinical results showed good in 73% and fair in 27% of cases. There were no complications such as wound infection and skin necrosis, but traumatic arthritis were 2 cases. Conclusion: Pilon fractures are high energy injuries with significantly associated soft tissue damage and traumatic arthritis. Limited internal fixation offers good solution to Ovadia and Beals type II or III fracture.

  • In order to study the heat transfer and pressure drop of an internal heat exchanger for $CO_2$ heat pump under cooling condition, the experiment and numerical analysis were performed. Four kinds of internal heat exchangers with a coaxial tube type and a micro-channel tube type were used. The experimental apparatus consisted of a test section, a power supply, a heater, a chiller, a mass flow meter, a pump and a measurement system. The section-by-section method and Hardy-Cross method were used for the numerical analysis. The effects of the internal heat exchanger refrigerant flow rate, the length of the internal heat exchanger, the operating condition of the gas-cooler, the evaporator and the type of the internal heat exchangers were investigated. With increasing of the flow rate, the heat transfer rate increased about 25%. The heat transfer rate of the micro-channel tube type was higher about 100% than that of the coaxial tube type. With increasing of the length of the internal heat exchanger, the heat transfer rate increased about $20{\sim}50%$. The pressure drop of the low-side tube was larger compared with that of the high-side tube.

  • As societal development improves the quality of life and changes the structure of society, the needs of the residents have been varied. As a result, the spaces in Korean houses have also been varied. This phenomenon can be found in both external and internal spaces; a transitional space, which connects the outside space and the inside space, is formed as transition occurs at each phase of movement. As the importance of external and internal spaces is emphasized, and as internal spaces are extended to the exterior, various forms of transitional space are needed. In this study, the boundary types of internal/external spaces are analyzed through transitional spaces that are formed in relation with internal and external spaces. Based on the analysis, transitional spaces in modem Korean houses are classified into the addition type, the cutting type, and the connection type. The results of the study show that transitional spaces in detached houses tend to be placed closely to rooms and a public space, and in terms of material use, the externalization of internal spaces is occurring.

  • Presented here are the results for clinical study on 65 cases of simple goiter the author treated during the period of 4 years and 10 months from Jan. 1963 through Oct. 1967 at the Seoul National University Hospital and Han-Il Hospital. It had been customary to classify simple goiter, according to the gross morphological characteristics of the thyroid gland, as diffuse and nodular type. This paper attempts to investigate the histopathological changes and treatment of simple goiter respectively. Sixty five cases of simple goiter were classified into 4 types; namely degenerative type was 20 cases (30.8%), proliferative type was 7 cases (10..8%), colloidal type was 24 cases (36.9%) and cyst formation with degeneration was 14 cases (21.5%), on the basis of histopathological findings. Thus, it is essential that simple goiter should be differentiated from thyroid tumors as soon as practicable. The effectiveness of medical treatment with desicated thyroid and autohemotherapy for certain simple goiter are also discussed.

  • Purpose: In this study, the loosening torque test was conducted with three implant products that are produced, approved and sold in Korea, which are manufactured in different fixture and abutment tightening methods (internal submerged type, internal morse taper type, and external type) to examine the loosening torque of the screw according to the method of tightening the implant fixture and abutment. Methods: In the loosening torque test, the three types of fixtures and abutments with different tightening methods were tightened by rotating them clockwise with a $30N{\cdot}cm$ force using a driver equipped with an electric torque meter. The results of the test are as follows. Results: The loosening torque values of the internal submerged type, internal morse taper type and external type implants were $24.10{\pm}0.742N{\cdot}cm$, $29.10{\pm}1.710N{\cdot}cm$, and $26.60{\times}1.636N{\cdot}cm$, respectively. Conclusion: The screw loosening torque values of the three fixture and abutment tightening methods were analyzed via Kruskal Wallis test layout, and they were significantly different (p<0.05).
