The twin-roll type strip continuous casting process(or direct rolling process) of steel materials is characterized by two rotating water cooled rolls receiving a steady supply of molten metal which solidifies onto the rolls. A solidification analysis of molten metal considering phase transformation and thermofluid is performed using finite diffefence method with curvilinear coordinate to reduce computing time and molten region analysis with arbitrary shape. An enthalpy-specific heat method is used to determine the temperatures inthe roll and the steel. The temperature distribution of cooling roll is calculated using two dimensional finite element method, because of complex roll shape due to cooling hole in rolls and improvemnt accuracy of calculation result. The energy equaiton of cooling roll is solved simultanuously with the conservation equaiton of molten metal in order to consider heat transfer through the cooling roll. The calculated roll temperature is compared to experimental results and the heat transfer coefficient between cooling roll surface and rolling material(steel) is also determined from comparison of measured roll temperature and calculated temperature.

This study was performed to determine the kinetic friction coefficient bulk density, dynamic and static angle of repose, and terminal velocity of the chopped rice straw in the moisture range of 8~23%, which could be used for better design and operation of the processing machinery and handling facilities. Friction coefficient was determined from the horizontal traction force measured by pulling the container holding the mass of rice straw on the various plate materials. Bulk density was measured with an apparatus consisting of a filling funnel and a receiving vessel. Dynamic angle of repose was calculated from the photos of bulk samples piled by gravity flow on a circular platform. Static angle of repose was determined by measuring the side angle of the bulk material which was left in the cylindrical container after natural discharge of the bulk sample through a circular hole in the bottom plate. Kinetic friction coefficients of rice straw on the PVC, mild steel, stainless steel, and galvanized steel were in the range of 0.303~0.434, 0.222~0.439, 0.204~0.448, and 0.206~0.407, respectively. and indicated linear increase with moisture content. The effects of moisture change on the friction coefficients were in the order of PVC, mild steel, galvanized steel, and stainless steel. Bulk density, dynamic and static angle of repose, and terminal velocity were in the range of 56.8~60.3 kg/m$^3$, 41.4~45.9$^{\circ}$, 94.4~100.8$^{\circ}$, and 1.07~4.48 m/s, respectively, and were increased linearly with the moisture content.

Atayal studied in this paper is one of the indigenous tribe in Taiwan, which is receiving considerable publicity gradually. Atayal has a quite unique traditional dress and custom as facial tattoo. The study was limited to the conventional culture of body adornment of the Atayal including the clothing which is less preserved and practicing by them at the present day, and the origin and the process of the historical development of those are just a little included in the scope of the present study. Through this study, we can get know about indigenous tribe's cultural background, such as their life, custom, religion, and the influences on traditional costumes. As for the research method, I examined the Atayal's traditional costumes and clothing through related books, magazine, research papers, internet sites, and etc. I also examined the common ground between facial tattoo patterns and their clothing using reference books and official web-site. Traditional clothing materials, basic forms of dress, and the pattern and technique of facial tattoo were examined in the present study in order to deepen the appreciation of the cultural heritage of the Atayal. In way, I hope this study will make a contribution to the field of Korean fashion industry which intends to enter Taiwan market.

Objectives: The purpose of the study was to investigate the basic materials required for law revision regarding dental hygienists through perceptions and opinions of legislation amendments. Methods: The study was conducted from April 23, 2016. A self-reported questionnaire was completed by 797 dental hygienists in Seoul and Gyeonggido after receiving informed consent from institutional review board (IRB No. PO1-201602-23-001). Results: Necessity for dental hygienist-related medical law revision accounted for 92.4% and 85.4% of dental hygienists replied that specialized dental hygienist system must be established. The reasons for medical law revision were as follows; roles and education of medical technicians (60.6%), settlement of medical legal problems (48.0%), cooperation with other organizations (29.0%), political negotiations (17.4%), and national consensus (9.5%). The score for 'possible to get legal protection by the system establishment of roles and work scope of dental hygienists' was 4.11 of 5 points. Conclusions: It is important to establish the job scope of dental hygienist. The revision of dental hygienist-related law will help to enhance the status of dental hygienists as professional medical technicians in the future.

Purpose: We did a retrospective study to understand the prognostic effects of preoperative blood transfusions in stomach cancer surgery. Materials and Methods: Data for 1,360 patients who underwent gastrectomy for stomach cancer between 2001 and 2009 were retrospectively reviewed. We analyzed factors that affect preoperative transfusion and clinicopathologic features. We also analyzed 5-year and overall survival rates of the transfusion and non transfusion subgroups. Results: Sixty patients (4.4%) required blood transfusion within the preoperative period. The transfused group included patients who took aspirin or clopidogrel (P<0.001), with more advanced T stages (P<0.001), with more advanced nodal metastasis (P=0.00), and with more advanced stages (P=0.00) than the non transfusion group. On multivariate analysis, preoperative transfusion was a statistically significant negative influence on 5-year survival and overall survival rates (58.2% vs 79.9% (P=0.00), 58.2% vs 76.8% (P=0.00)). Applying Cox-regression analyses, blood transfusion did appear to have an effect on prognosis and on 5-year and overall survival rates. Conclusions: We found a direct negative relation between preoperative transfusion and long term prognosis in patients receiving gastric cancer surgery.

An optical fiber displacement sensor has the advantages of relatively simplicity, cheap, small probe size and immunity against environmental perturbation. The working principle of the sensor is based on the intensity modulation that is detection light intensity reflecting from the surface being measured. This paper presents the mathematical model of displacement measurement mechanism of this sensor type. The theoretical and experimental data are compared to verify the model in describing the realistic approach to sensor design. Finally, the analysis results show that displacement response characteristics such as sensitivity, measuring range are easily modified by principal design parameters such as magnitude of optical Power, diameter of optical fiber core and distance between transmitting fiber and receiving fiber.

Ultrasonic metal welding, unlike the conventional welding techniques, does not require an external heat source, welding rod, or filler metal. Therefore, ultrasonic metal welding is not only economical but also environment-friendly, and hence, it has been receiving much attention. In ultrasonic welding, heat is generated because of the plastic deformation and the friction between both surfaces of the welded materials. It is important to identify the heat-affected zone by measuring the temperature generated at the weld. In this study, the effects of the welding pressure, welding time, and vibration amplitude on the temperature distribution in the weld were evaluated by performing a transient thermal analysis of the heat generated during ultrasonic metal welding. The experimental results indicated that the temperature of the weld tends to increase with the welding time and vibration amplitude. However, an increase in the pressure does not affect the temperature of the weld largely.
