In pathologically analyzing, 'Qi(氣)' is fall downed 'Zheng-Qi(正氣; Base energy of human body)' or 'Wai-Gan-Xie-Qi(外感邪氣; poisoned energy from outside of human body)'. And all extroverted symptoms from this 'Qi(氣)' is 'Shang-Chong(上衝)'. Also this symptom's basic mechanism is deficiency of 'Zhong-yang(中陽; basic active energy acting pivot)' by non-proper 'Xia-fa(下法; treatment way getting out focus to down side)' at early days of 'Tai-Yang-bing (太陽病; Primary stage symptoms when the cold energy of the outside tresspasses the external layer of body)'. And comparing herbs in medicines for treating 'Shang-Chong(上衝)' in Shang han lun with Japanese in Shang-han medical practitioner's view, there is 'Ping-Chong(平衝; Supress out bursting energy)''s effect when use 'Gui-zhi(桂枝; Cinnamomum cassia loureirii zeylanuicum)' for mass dosage. Based on these, 'Qi-Shang-Chong(氣上衝)' means all of the symptom's aspects which called 'Yang(陽)''s aspect that is extrovesity, dynamic and imminent by results of the experiment about Cinnamaldehyde which are the main ingredients of 'Gui-zhi(桂枝; Cinnamomum cassia loureirii zeylanuicum)' and clinical data of 'Gui-zhi-tang(桂枝湯)'.

Fluid film tilting pad journal bearings are widely used for large steam turbines. However, bearing problems by pad fluttering, such as fatigue damage in the upper unloaded pad, the break of locking pins and the wear of pinholes etc., are frequently taken place in the actual steam turbines. The purpose of the present work is to investigate on the mechanism of pad fluttering and the prevention of pad fluttering with the variation of preload(m) in a tilting pad journal bearing. It is estimated that upper pad is easy to flutter because the film shape of upper pad is diverged one from the analysis of moment direction acting on pivot point. Effective preload range in order to be statically loaded pad under all operating conditions is suggested as m＞0.5. Also, as a bearing that can be prevented pad fluttering, design modified bearing is suggested. For the adjustment in actual steam turbines, bearing and rotor dynamic analysis are performed to identify bearing characteristics and to verify the reliability of rotor-bearing system.

It is becoming more significant to develop a rotary VCM type actuator for small form factor ODD, as portables are getting more and more popularized nowadays. In this paper, the procedure of development of the actuator which is applicable to compact flash II card and is fit in the specification of BD 1X is explained. This is based on the rotary VCM type actuator, which is good for reducing thickness. Air core solenoid coil is used in order to do focusing mechanism. And the total weight is reduced by using the structure of steel-aluminium-steel triple layer, so, the stiffness is still adequate. Additionally, the tracking coil is moved next to the actuator, so the total length was reduced, then the actuator become applicable to compact flash II card. The force of Magnetic Circuit is improved by using Magnetic Circuit DOE. And flexible mode frequency improved through the DOE of structure part. Modeling was exactly done in consideration of air core solenoid coil and pivot bearing. It is confirmed that the designed model is satisfied with the specification of BD 1X and is applicable to Compact Flash II card.

This study was carried out in order to investigate Korean food acculturation by married immigrant women and how it affects their children's eating habits. Using an in-depth interview method, 26 domestically residing married immigrant Chinese, Vietnamese, and Indonesian women in Korea were surveyed to investigate adaption to Korean food at the time of their immigration, their current dietary life, their preferred Korean food, major factors in managing their children's eating habits, etc. The results reveal that depending on the married immigrant women's country of birth, which plays an important role in a family's dietary life and health, acculturation phenomena occurred in which the specific eating habits of each country were grafted into Korean food. Furthermore, due to their school-age children's display of acceptance of both their homeland's and Korea's food culture, we believe that this can become a pivot point for non-governmental diplomacy where Korean food can be understood along with the mothers' countries.

Mobile devices have become an important part of daily life. This is especially true of laptop PCs, which are portable enough to be used almost anywhere. Laptop PCs, however, cannot be nomadic if each component is not robust enough to endure rugged laptop operating environment. Generally, external shock makes collision on head-disk interface and damage to read-write performance. To minimize the likelihood of failure, shock analysis must be incorporated into the design of hard disk drive in laptop. This research explores the structure modification of laptop HDD base, for improving shock performance using finite element analysis which considers the flexibility of whole HDD structure. FE model is verified by modal test and finely tuned. Then we obtained the transmitted acceleration of spindle and pivot and the relative displacement between disk and slider head as shock response. Based on shock simulation, the structural dynamics modification is performed and the primary design parameters are extracted.

Modern small modular nuclear reactors can be built on a barge in ocean, therefore, their flow characteristics depend upon the ocean motions. In the present research, effect of rolling motion on flow and friction characteristics of laminar flow through vertical and horizontal narrow channels has been studied. A computer code has been developed using MPS method for two-dimensional Navier-Stokes equations with rolling motion force incorporated. Numerical results have been validated with the literature and have been found in good agreement. It has been found that the impact of rolling motions on flow characteristics weakens with increase in flow rate and fluid viscosity. For vertical narrow channels, the time averaged friction coefficient for vertical channels differed from steady friction coefficient. Furthermore, increasing the horizontal distance from rolling pivot enhanced the flow fluctuations but these stayed relatively unaffected by change in vertical distance of channel from the rolling axis. For horizontal narrow channels, the flow fluctuations were found to be sinusoidal in nature and their magnitude was found to be dependent mainly upon gravity fluctuations caused by rolling.

H. Kim, B.K. Lee and C.K. Rheem have been experimentally studied to clarified the mechanism of thrust force generated by sculling motion for the propulsion of Korean small boats. The experimental investigations have been conducted under the bollard condition by installing a scull at the end of a trimming tank of towing tank. The sculling motion produced by the skilful fisherman and the resultant venerated forces have been measured in respect to the Cartesian coordinate fitted to the pivot point of the scull. ("An Experimental Study on the Propulsive Characteristics of Sculls". J. of the Soc. of Naval Arch. of Korea, Vol. 26, No. 3, 1989, pp.13-24) Through these experiments the trajectory of the blade tip and the angular displacement of the blade section have been measured as shown in Fig. 1 and 2 of this paper. And at the same time the resultant hydrodynamic force components are expressed in Fig. 3 and 4. These three dimensional data of sculling motion and generated real time force components are the unique experimental information which could clarify the thrust force generating mechanism of sculling motion. The experimental results have been reanalyzed by focusing the relation between instantaneous attack angle of blade section and the resultants real time force components. Through these investigation it is found out that the conventional imagination that the 7cull motion should be effective in generating lift force must be reconsidered because the attack angle of scull blade are too great to free from stall phenomena during the sculling operation.
