This paper aims at the comparative study of practicing Buddhism and Taoism related to "life gate". The term "life gate", as a physiological entity of disputed morphological identity, first appears in The Inner Canon where it refers to the eyes. Reference to a "life gate" as an internal organ body first appears in The Classic of Difficult Issues which states, "The two kidneys are not both kidneys' The left one is the kidney, and the right is the life gate." Successive scholars refers to life gate as a gi point of Taoists.. The question of the life gate invited little discussion until the Myeong and Cheong Dynasty, when various different theories were put forward. Especially Jin Sa-taek says "life gate" is the governor of the twelve place in the human body, throwing light on the meaning of it. Not that life gate denotes a local point, it does a system of life gate. Generally speaking, life gate designates cinnabar field. I think that the human body produces essence by way of life gate. That is, the human body is unified by the system of life gate. Life gate is not only the source of infusing the engine of the human body with vital energy but also as well as gi-point.

Objective : There was no attempt to understand Moving Energy between two kidneys(腎間動氣) and Kidney on Left & Life Gate on Right(左腎右命門) by integration progress. So I have faced to study based on two parts with concerning as clues. One is 'Life Right (左 右)' and the other is 'Between(間)'. Methods : Revealing the source of the origin, Nanjingbenyi(難經本義) is given on the basis. Take a close look at publications related to Nanjing(難經) which is about Kidney on Left & Life Gate on Right and Moving Energy between two kidneys. Take a close look at Kidney, the Life Gate and Moving Energy between two kidneys. Look see the three-dimensional uplift movement of Gi(氣). Results : In Neijing(內經) and Nanjing, the basic point of view for Kidney is the same. That is explained in line with attributes of convergence(收斂). 'Life Gate(命門)' is a term to express the divergence feature(發散機能) of kidney. Moving Energy between two kidneys is used to mean the mainspring of human body activity. The Gi in human body loses altitude turning left(左旋而下降) and gains height turning right(右旋而上升). Conclusion : Watching on functional aspect, there are two names for kidney. One is 'Kidney(腎)' which collects the losing altitude turning left and the other is 'Life Gate' which rises turning right. Moreover, the fundamental power that effectuate the uplift movement is Moving Energy between two kidneys. This kind model is a way that can be understood syntagmatically the Kidney on Left & Life Gate on Right and the Moving Energy between two kidneys without any gainsaying the original of Nanjing.

This study is to know the concept and function of Vital Gate. The results are summarized as follows, 1. Vital Gate is the original of life, which is essential to life. 2. A physiological function of Vital Gate controls the physiological activity of the whole body through Triple Heater. 3. It is said that a partial establishment of Vital Gate is the concept of Hwang Jeong(黃庭) as the central point of the body. 4. It is effective that a clinical application of Vital Gate uses on the basis of Zoagyuyeum(左歸飮) and Woogyuyeum(右歸陰). 5. Fire of the Vital Gate means a original activity of life-activity and is different from the concept of the fire of Pericardium as a substitute for King Fire. 6. It is said that to explain the essence of Vital Gate in relation of kidney is to say the generative function. According to the above results, Vital Gate is understood as the control of physiological activity of the whole body as the original point of life-activity.

These Study are for the development of the reliability assessment test code and test equipment and test procedures of the heavy sluice gate hydraulic cylinder. Because there is no reliability test code for the heavy sluice gate hydraulic cylinder inside and outside of the country, the modified reliability test code is made reference for the related existing standards like as ISO, JIS, MIL, TUV, DIN, KS and etc. In this study, the novel method is proposed to evaluate efficiency of the heavy sluice gate hydraulic cylinder on the loading conditions and established the conditions of the acceleration life test to reduce the testing time and cycles. The testing equipments for life test, lode operating test, high and low temperature test and salt spray test have been established for 8 month, and the reliability tests are accomplished. The test results of the heavy sluice gate hydraulic cylinder which is produced and tested initially in Korea are satisfied the durability life cycle on the using conditions.

Gate-lifting devices in small- to mid-sized sluice gates mostly employ the mechanical roller rack pinion (RRP) system. This RRP system, which consists of a rack-bar and a pinion, transforms a rotation motion into a linear one. The rack-bar has a series of roller trains that mesh with the pinion. In this study, we adopt an exact involute-trochoid tooth profile of the pinion to obtain a higher contact fatigue strength using the profile modification coefficient. Further, we determine the contact forces and investigate Hertz contact stresses to predict the pitting life of the pinion according to varying the shape design parameters. The results indicate that the design fatigue life of an RRP system for sluice gate can be achieved only when the design value of the profile modification coefficient reaches or exceeds a certain level.

This study examines the variation in diagrams of the kidney, and the effects on location of the Life Gate as a result. My study analyzes diagrams of kidney form and location, such as appearance, the vertebral spine, ShenXi, and "Life Gate", and also explores the causes for such variations. The kidney is commonly described as having the shape of a bean, which throughout medical history has showed almost no variation. The spine was initially described with a total of 21 vertebrae, and later with a range of 19-25 vertebrae. Regarding the height of kidney in relationship to the spine, it was initially described as beginning at the 14th vertebrae, and later changed to the 15th or 17th vertebrae. However, there have been no changes in the perception of the height of kidney. Initially, the location of the Life Gate could not be identified. Three different suggestions of its location were found throughout historical literature, including: (1) at or within the right kidney; (2) between two kidneys; and (3) between 14th-15th spine. There were also variations noted in the process of copying diagrams of kidney in many books not only because the work of copying was not precise, but also because each medical practitioner had a different interpretation of the kidney's form and function in Traditional Korean and Chinese Medicine. It appears that some practitioners may have been influenced by their understandings of theory of Life Gate.

The purpose of this study was to improved the durability of a improved movable weir by replacing the improved movable weir's metal gate with a hybrid steel/glass fiber reinforced polymer composites panel gate. Because the metal gate of a improved movable weir is always in contact with water, its service life is shortened by corrosion. This study made four type of hybrid steel/glass fiber reinforced polymer composites panel gate with different steel gate surface deformation (control, sand blast, scratch and hole), flexural. Fracture properties tests were performed depending on the steel gate surface deformation. According to the test results, the flexural behavior, flexural strength and fracture properties of hybrid steel/glass fiber reinforced polymer composites panel gate was affected by the steel panel gate surface deformation. Also, the sand blast type hybrid steel/glass fiber reinforced polymer composites panel gate shows vastly superior flexural and fracture performance compared to other types.

This thesis analyzes various becomings of female characters in Rose Gate written by Tie Ning. By this analyzation, we can pick out what identity the female characters eager to have decomposed, what identity they hope to create, and what do these procedures mean. Si Qiwen's 'becoming male' presents strong desire to shift from periphery to center. However, it is meaningless when her tragic life can not be justified by those same female people. Zuxi's 'becoming wanderer' shows that Tie Ning refuses usual reality of woman's life which vest in man. Sumei's 'becoming mother' is the exact point where torn female ego gets to consolidate, and it means Tie Ning takes 'mother-becoming' as ultimate truth of woman's life. Besides, Tie Ning finds women's becoming something new as escaping from the other and she denies equation of man with savior.

Small valves including ball valves, gate valves and butterfly valves have been adopted in the fields of steam power generation, petrochemical industry, carriers, and oil tankers. Butterfly valves have normally been applied to fields where in narrow places installing the existing valves such as gate valves and ball valves have proven difficult due to the surrounding area and the heavier of these valves. Butterfly valves are used to control the mass flow of the piping system under low pressure by rotating the circular disk installed inside. The butterfly valve is benefitted by having simpler structure in which the flow is controlled by rotating the disc circular plate along the center axis, whereas the weight of the valve is light compared to the gate valve and ball valve above-mentioned, as there is no additional bracket supporting the valve body. The manufacturing company needs to acquire the performance and life test equipment, in the case of adopting the improving factors to detect leakage and damage on the seat of the valve disc. However, small companies, which are manufacturing the industrial valves, normally sell their products without the life test, which is the reliability test and environment test, because of financial and manpower problems. Furthermore, the failure mode analysis of the products failed in the field is likewise problematic as there is no system collecting the failure data on sites for analyzing the failures of valves. The analyzing and researching process is not arranged systematically because of the financial problem. Therefore this study firstly tried to obtain information about the failure data from the sites, analyzed the failure mode based on the field data collected from the customers, and then obtained field data using measuring equipment. Secondly, we designed and manufactured the performance and life test equipment which also have the real time monitoring system with the naked eye for the butterfly valves. The concept of this equipment can also be adopted by other valves, such as the ball valve, gate valve, and various others. It can be applied to variously sized valves, ranging from 25 mm to large sized valves exceeding 3000 mm. Finally, this study carries out the life test with square wave pressure, using performance and life test equipment. The performance found out that the failures from the real time monitoring system were good. The results of this study can be expanded to the other valves like ball valves, gate valves, and control valves to find out the failure mode using the real time monitoring system for durability and performance tests.

This research was to identify housing identity expressed on entrance features In Korean single detached houses. The data were collected from field study and content analysis method of 45 houses in Chonju city. The methods of observation, of measuring the size, of sketching. and of Photos of entrance feature in the single detached houses were used for this study. Results of this study were as follows. First. the height and the form both of main gate and of wall tended to be closed. In particular. the size of main gate tended to be shown off rather than having practical funtion. whereas the form of main gate were semi-opened and thus could not guaranteed privacy of the residents very well. Second, 53.3% of the direction of main entrance were found to be at right-an91e0 with main gate, which reflected the control needs of private life. Third. the balance of main gate and exterior was homogeneous, which expressed the increase of aethetic concern of exterior Finally. most of entrance approach were made of stones and bricks. This result indicated that the practical funtion of entrance approach was emphasized the emotional environment was not considered in building the entrance approach.
