  • The burial custom in the Youngsan river area was to build a jar-coffin and lay the body in state, however the methods in building and moulding the massive jar, as well as in which kiln it was made has not been examined precisely. Thus, this research not only investigates previous results related to the manufacturing methods of massive jar-coffins, but also examines samples that were excavated and collected. The clay used to produce jar-coffin consists a large portion of unglazed qualities, which was split-moulded from the bottom up to the mouth area. The interior was finished by applying water, whereas the exterior was decorated by regularly pasting or stamping in parallel with a lattice design. It can be presumed that the finished jar-coffin was not moved, but the ceiling and walls were built around it as a kiln, for the jar-coffin to be oxidized or to reduce the flame condition in a temperature approximately $700~1,200^{\circ}C$The results from the research, however, show limitations to exploit the exact manufacturing method, therefore there is a need for in-depth examinations: mineralogical investigation on a large amount of jar-coffin samples through a polarized light microscope; substance analysis using various equipments; speculation on the temperature in the place of production and the flame inside.

  • A nonlinear analysis of torsional self-excited vibration in the driveline system for wheeled towing tractors was presented, with a 2-DOF mathematical model. The vibration system was described as a second-order ordinary differential equation. An analytical approach was proposed to the solution of the second-order ODE. The mathematical neighborhood concept was used to construct the interior boundary and the exterior boundary. The ODE was proved to have a limit cycle by using $Poincar\'{e}-Bendixson$ Annulus Theorem when two inequalities were satisfied. Because the two inequalities are easily satisfied, the self-excited vibration is inevitable and even the initial slip rate is little. However, the amplitude will be almost zero when the third inequality is satisfied. Only in a few working modes of the towing tractor the third inequality is not satisfied. It is shown by experiments that the torsional self-excited vibration in the driveline of the vehicle is obvious.

  • 1. Objectives: This study examines the pathologies that originate from a Common Root Pathologic Category(CRPC; 同出一屬) in the Soyangin that are suggested in the Sasang Constitutional Medicine(SCM). 2. Methods: The changes in concepts and perceptions on the Soyangin pathologies were compared across the different editions of Donguisusebowon, "Donguisusebowon, Gabo edition(東醫壽世保元甲午本) (DGO)" and "Donguisusebowon, Sinchuk edition (東醫壽世保元辛丑本) (DSC)". 3. Results and Conclusions: The Soyangin pathologies originating from a CRPC that are described in Donguisusebowon are actually detailed classifications of the Yin-deficiency Diurnal-heat symptomatology (陰虛午熱證) and the Chest-congestion symptomatology (結胸證). Lee Jema had introduced the concept of "Common Root Pathologic Category(CRPC)" to approach pathologies of similar exterior/interior classification or severity stage (mild/moderate/severe/critical) by combining them in a comprehensive, integrative pathology system. This comprehensive approach, which promotes better understanding of the Soyangin pathology and maximizes the therapeutic efficiency of SCM, constitutes the "Comprehensive Therapeutic Methodology" that is the hallmark of Sasang therapy.

  • To satisfy safety regulations of Economic Commission for Europe (ECE), the surface regions of automobile parts must have a sufficient degree of roundness if there is any chance that they could contact a sphere of 50.0 mm radius (exterior parts) or 82.5 mm radius (interior parts). In this paper, a new offset-based method is developed to automatically detect the possible sphere-contacting shape of such parts. A polyhedral model that precisely approximates the part shape is given as input, and the offset shape of the model is obtained as the Boolean union of the expanded shapes of all surface triangles. We adopt a triple-dexel representation of the 3D model to enable stable and precise Boolean union computations. To accelerate the dexel operations in these Boolean computations, a new parallel processing method with a pseudo-list structure and axis-aligned bounding box is developed. The possible sphere-contacting shape of the part surface is then extracted from the offset shape as a set of points or a set of polygons.

  • This study examined the carbon dioxide ($CO_2$) pollution inside vehicles under low ventilation condition and evaluated the Air Quality System (AQS) for in-vehicle air quality using two techniques. The low ventilation condition is not recommended in order to keep oxygen-rich condition inside vehicles. Under the low ventilation condition, the in-vehicle $CO_2$ concentrations exceeded 1,000 ppm, the air qualify guidelines in the United States, Western Europe, and Japan, indicating more oxygen deficiency inside vehicles. On the contrary, with the AQS-on condition, the in-vehicle $CO_2$ concentrations were less than 1,000 ppm fer most of the driving time, indicating that the AQS could solve the problem of $CO_2$ accumulation inside vehicles under the low ventilation condition. The AQS test conducted by comparing carbon monoxide (CO) and volatile organic compound (VOC) concentrations inside two vehicles indicated that the AQS effectively decreased the in-vehicle concentrations by 21 to 36%, as compared to medium ventilation condition with the windows closed, the vent opened, and air conditioning on. In addition, The AQS test conducted by comparing the interior and exterior concentrations indicated that the AQS effectively decreased the in-vehicle concentrations by 18 to 31%, as compared to medium ventilation condition.

  • The purpose of this article was to research the effects of physical environment on risk perception in customers at raw-fish restaurants in the Northeastern area of Kangwon province, South Korea. In this research, reliability analysis, factor analysis and path analysis were carried out. Physical environments were divided into four factors and risk perception into three factors. 'Exterior facility' had a negative influence on performance (p<0.001) and financial risk (p<0.001). 'Interior facility' negatively affected performance risk (p<0.001), financial risk (p<0.001) and time risk (p<0.001). 'The others' negatively influenced performance risk (p<0.05). Lastly, 'press copy' negatively influenced performance risk (p<0.001). Based on these results, various physical environments affected the risk perception in customers at raw-fish restaurants, and satisfaction level of customers was based on risk perceptions. As a result, food-service companies need to manage the physical environment as a marketing strategy, as well as reduce risk perception to increase customers loyalty.
