Objective : The objective of this study is to explore the meaning of 弦 in Shanghanlun through analyzing two cases. Methods : Two cases treated with modified Soshiho-tang, which is administrated when 弦 aggravates chief complaints, were analyzed. All of the cases were diagnosed by disease pattern identification diagnostic system based on Shanghanlun Provisions. Results : The patients' chief complaints of all 2 cases were improved after administration of modified Soshiho-tang. As pulling symptom was reduced in all 2 cases, patients' disease were relieved. Through the etymological research and clinical treatment results, the clinical meaning of 弦 is deduced as 'pulling'. Conclusions : The etymological and clinical analysis suggest that the concept of '弦' maybe defined as 'pulling' in Shanghanlun.

E. H. KIM, E. S. CHOI, D, H. NAM, S. S. KIM, J. W. CHUNG and T. W. KIM, The Instrumenfal Development for Pulling . Reaping Training & Measuring in Judo.Korean Jiurnal of Sport Biomechanics, Vol. 18, No. 1, pp. 213-226, 2008. The purpose of this study was to develop a judo-doll uke(partner : doll-uke) for training and measurement applicable to pulling, pushing and reaping in judo. In Judo the most common techniques consist of the pulling, pushing and sweep which all need to be practiced with a partner. So the research needs to develop a measurement system that can be used to evaluate the forces involved with these techniques. Also the Doll-Uke must be developed so that judokas can train alone. After the manufacture of Doll-Uke the usefulness of it must be evaluated. The height of a Doll-Uke is l70cm and its weight is 50kg. Doll-Uke was developed with a trunk angle of 55 and the lower extremities of an angle of 45. The Doll-Uke can also measure the forces developed during the pulling, pushing and sweep. Due to the ability of the system to measure the forces while preforming Judo techniques feedback can be provided to the Judokas to improve their performance.

Most mono-crystalline silicon ingots are manufactured by the Czochralski (Cz) process. But If there are oxygen impurities, These Si-ingot tends to show low-efficiency when it is processed to be solar cell substrate. For making single-crystal Si- ingot, We need Czochralski (Cz) process which melts molten Si and then crystallizing it with seed of single-crystal Si. For melts poly Si-chunk and forming of single-crystalline Si-ingot, the heat transfer plays a main role in the structure of Cz-process. In this study to obtain high-quality Si ingot, the Cz-process was modified with the process design. The crystal growth simulation was employed with pulling rate and rotation speed optimization. Studies for modified Cz-process and the corresponding results have been discussed. The results revealed that using crystal growth simulation, we optimized the oxygen concentration of single crystal silicon by the optimal design of the pulling rate, rotation speed and melt charge level of Cz-process.

Yb and Zn co-doped $LiNbO_3$ single crystal rods which had a diameter of 2 mm and a length of $15{\sim}25 mm$ were grown by micro-pulling down (${\mu}-PD$) method. The single crystals were successfully grown and had a uniform diameter and a smooth surface without crack. We realized of $LiNbO_3$ single crystals were hexagonal structure to compare with peaks of $LiNbO_3$ powder by Raman spectra. The threshold level of Zn concentration which is effective for optical damage were observed as about 1 mol% with IR transmission spectra.

Objectives: The purpose of this study was to provide basic data for gingivitis management programs by dental hygienists by evaluating the effect of oral health education, oil pulling, and professional toothbrushing on gingivitis. Methods: A total of 38 subjects were divided into three groups: control group (12 subjects), experimental group 1 (13 subjects), and experimental group 2 (13 subjects). The control and experimental groups were instructed to brush using the rotating method. Distilled water was provided to the control group after training. Coconut oil was provided every morning for about 10 minutes. In the experimental group 2, a professional brushing method was used at each visit. Results: There were no significant differences in oral health among the three groups, and there was homology between patient hygiene performance (PHP) index (p=0.144) and bleeding rate (p=0.213). The PHP index showed a significant interaction between the group and measurement time. The control and experimental groups showed changes in the PHP index with time (F=3.711; p=0.013). The bleeding rate showed a significant interaction between the group and measurement period. The control and experimental groups showed changes in the bleeding rate with time (F=6.707; p<0.001). Conclusions: Oral health education, professional toothbrushing, and oil pulling specialists in oral care of gingivitis were effective in managing gingivitis. It is necessary to educate people on self-management methods for oral health promotion using gingivitis management programs by dental hygienists.

The $Bi_2Sr_2Ca_{n-1}Cu_nOy$(BSCCO) phase is well known to be a superconductor having a strong anisotropic behavior. It can be seen that it is difficult to control the growth direction. In this study, we try to grow a Bi-Sr-Ca-Cu-O phase crystal by the crystal pulling method with a seed crystal and crucibel rotation. Relatively large crystals of the order of $5{\times}5{\times}5{\textrm}{mm}^3$ dimensions can be obtained. We also discuss the possible crystallization field of the $BiO_{1.5}$-(Sr, Ca)O-CuO ternary phase diagram, and present some results of the characterization and magnetic measurements on the grown crystal.

The steady-state, incompressible and three-dimensional numerical analysis was performed to investigate the flow fields around the seabed tiller used for soil improvement in coastal fisheries and the pulling force and buoyancy generated by tiller operation. The turbulence model used in this study is a realizable $k-{\varepsilon}$. As a results, at a stationary current or a current speed of 1.2 knots, where rotor rotates in a clockwise direction, a typical vortex pair appears near the tip of the rotor except for the edge, and the strength of the vortex pair increases with the number of revolutions of the rotor. The pulling force of the tiller rotating in the counterclockwise direction increases with the number of revolutions. Also, when the current flows at 1.2 knots and the rotor rotates clockwise, the pulling force of the tiller acts on the upstream side irrespective of the number of rotations of the rotor, so that no force is applied. The buoyancy of the tiller acts on the seawater surface if the flow direction inside the rotor is the same as the direction of rotation of the rotor, regardless of the current velocity, otherwise it acts on the seabed.

Using the micro-pulling down method, $Nd_2O_3$ doped crack-free stoichiometric $LiNbO_3$ single crystals were grown in 1 mm diameter and 30∼35 mm length. The homogeneous distributions of $Nd_2O_3$ concentration were confirmed by the electron probe micro analysis. The absorption and photoluminescence spectra were measured with respect to the $Nd_2O_3$ doping.
