Architecture is builded on the ground and affected environment which include shape of topography and situation. What this study saying is the analysis about the relation between the concept of structural geomorphology and the space modern architecture. As there are many issue about boundary of space and organic architecture, It is important what study about structural geomorphology In paper, we will aware that there are many similarities between architecture and topography. Notion of folded structure in structural geomorphology is connected with continuity or infinity. This is one of many example.

This study deals with evaluation of bending fatigue strength in shaving gears. The saying gears were manufactured by processes that are currently used in most gears manufacturing companies. The test gears are bobbed, then the tooth surface are treated by a combination of shaving, carburizing and shot peening. The constant stress amplitude fatigue test is performed by using an electro-hydraulic servo-controlled pulsating tester. The S-N curves are obtained and illustrated. In this study, the effect of shaving process and shot peening was investigated and evaluated quantitatively on the fatigue strength. The enhancement of fatigue strength due to shaving process and shot peening is clarified.

This study was conducted out of necessity for attempting to identify what degree of satisfaction contemporary beauticians having to accomplish this expanded role of theirs had and what factors had an effect on their job satisfaction. Based on the study results, the following conclusion was drawn: 1) It was found that beauticians‘ level of job satisfaction with its components was in the order of 'vocational pride'(3.66), 'human relations'(3.39), 'autonomy'(3.29), 'required job'(3.13), and 'vocational duty'(3.01). 2) It was found that as to the level of job satisfaction according to religions beauticians with Buddhism had the highest level of job satisfaction with each of its components, followed by 'Others'(3.37), 'Christianity'(3.26), 'Catholicity'(3.25) and 'No Religion'(3.24). 3) It was found that as to the level of job satisfaction according to the future plan beauticians saying 'I will stop working at the same time that I marry'(3.68), 'I will continue working'(3.33), 'I will work for several more years'(3.30) and I will stop working at any time depending on circumstances'(3.29).

Zhang Jie Bin had a lot of influences on the oriental medical world to write Lei Jing(類經) and Lei Jing Tu Yi(類經圖翼). His oriental medicine is based on profound philosophy. In this thesis, he understand the thousand year of chinese philosophy of ancient times in the reign of Song, Yuan, and Ming dynasty and his view of the world which is revealed in Oriental Medicine is regarded as Qi(氣) and then Li(理) is considered not an object for a special purpose but an attribute of Qi(氣). The base which a debater is able to suggest like this is that because of his saying that Tai Ji(太極) is Yin and Yang(陰陽). The basis of his world is Qi Yi Yuan Lun(氣一元論) of Yin Yang Wei Fen(陰陽未分)

The depth and spread of root systems and the density of root branching affect the success and survival of plants subjected to drought. The type and size of root systems are controlled by heredity and soil conditions. There are also important interaction between roots and shoots; roots are dependent on shoots for carbohydrates, growth regulators, and certain vitamins, and shoots are dependent on roots for water, minerals, and certain growth regulators. Pinus thunbergii Parlatore had most of roots in the top 20cm of soil, and had little short of roots in the less than 80cm of soil. Average of root density was $270cm/cm^3$ in the upper soil(0~20cm). Root density of Pinus thunbergii Parlatore was similar to that of Cryptomeria japonica. There is no saying that Pinus thunbergii Parlatore has an advantage over Cryptomeria japonica in the drought. This data will be used to the root density values in the simulation model of black pine stands.

This paper studies Optical Fiber(OF) - LED illuminated display board system for energy saving. The OF-LED illuminated display board system has PV modules, batteries, and charge & discharge system, and dynamic full color display controller. Both maximum power point tracker (MPPT) and constant current & constant current controls (CCVC) are used In govern the charging system. It can be improve the charging efficiency of battery. The objective of this thesis paper is to build advertisement lighting system with OF-LED in to charge a 12-volts lead acid battery by using a field wired PV array. We saved the maintenance cost and developed of advertisement effectiveness. To verify the proposed OF-LED illuminated display board system for energy saving, the detail simulation and experiment results indicate that operating characteristics are verified by experiment with a laboratory prototype in this paper.

Because energy consumption of the construction part is very high, there is a growing need to introduce environment-friendly buildings. Therefore Green Building Rating System is enacted in Korea. Though environment-friendly factors such as green area affect the apartment housing price, there's no saying whether Green Building Rating System directly affect the apartment housing price. The purpose of this paper is to estimate the impact of Green Building Rating System on an apartment housing price. The analysis result demonstrated that Green Building Rating System don't affect the apartment housing price. This result means that there is a problem with the effectiveness of Green Building Rating System. The government ought to institute incentive program to ctivate the market of environment-friendly building.

An investigation into power conditioners that interface with photovoltaic array and utilities has been completed. The rating for this investigation is residential system(3-5kW) that interface with a 220V single phase utility connection. As the result of this investigation, a 3kW high frequency PWM IGBT inverter feeding a high frequency isolation transformer with a sinusoidal current wave was selected. The output of the transformer rectified with a diode bridge rectifier four IGBT, used as 60Hz switched, reverse the polarity of the rectified current on every other half cycle of the utility voltage. Even though the high frequency link system used more power semiconductors a net size, weight, and parts cost saying result compared to the other systems due to elimination of 60Hz transformer.

An electricity consumption is closely related to the economic growth structure. The change of economic growth structure affects the pattern of electricity consumption widely and severely. This paper gives that the primary changing factors of electricity growth are economic growth, change of industry structure(the change of electricity consumption ratio in case of residential sector), and the effect of electricity saying. It gives a model to analyze the influence of GDP to the change of electricity consumption patterns by sector through the period of pre and post 1998(IMF, financial crisis) to observe the contribution of each factor to the growth of electricity demand. It is anticipated that this study shows the feasible scheme of economic structure to become the developed country.

The role of the rescue party only function of accident hour relief activity it knows against the technique and an immediacy of Hum who burns executes an education and training and the accident it will be able to occur in advance and Hum activity hour which burns it prevents the place where it reduces it contributes a lot role is the importance is a possibility of saying that compared to it grows more. It must establish the cave structure commission inside Korean cave academic society and it must cooperate with the instance of the foreign nation together and with each other it must improve a cave structure setup and equipment and the countermeasure which is appropriate and prevention of accident inside the cave and accident occurrence hour it must consider feed with the fact that it must become.
