In this paper, we aim at establishing a generalized fractional integral version of Gr$\ddot{u}$ss type integral inequality by making use of the Gauss hypergeometric function fractional integral operator. Our main result, being of a very general character, is illustrated to specialize to yield numerous interesting fractional integral inequalities including some known results.

Resistivity of GaN has been investigated under the influence of ion implantation. n-type, p-type and also undoped GaN has been used here. A ring shape pattern of Au was fabricated on GaN film by the photolithography technique. H, He and Ar were used for implantation. The ion implantation energy, fluence and post-implant annealing temperature varied in this research. Because of the making barrier in some selected area using ions, the resistivity changed in all the samples with the change of both fluence and energy. At room temperature, the resistivity of n-type GaN has been increased from $1.9{\times}10-2$ to $17.7{\times}10-2\;{\Omega}-cm$. This is high for He ion. But undoped and p-type GaN showed some anomalous character.

Due to the complicated character of the hemming process for automobile panels, it is very difficult to set up a consistent and reliable die design guide rule that does not require subtle decision of experienced experts during design stage and multiple trials during hemming die making. In this paper an automatic die design system of hemming units is pursued by presenting some algorithms, in which geometric data and constraints of the hemming units were converted to formula. two kinds of hemming units, 2-link type and 4-link type, were selected as examples and the geometries and kinematics of all parts were analyzed to build the design algorithm.

The purpose of this study was to analyze the school location and site planning direction for land use planning of public land development. And this research proposed the direction of small park in school. So this research present the implication on urban planning and design for architecture, park-school complex. This study perform the relationship analysis on location of school and park. The result follows as this : 1) land use planning : Location and space of park-school must be checked in advance. Schools and parks are placed together. The park is located south of the school. 2) school site planning : Small field for dynamic activity is needed in school. The character of small park in school is relationship of educational programs. 3) management : CCTV is installed at school. Bright lights are placed in school. This result will be used in decision-making-process of land use planning, public land development construction, urban design and city policy.

In this paper, we find a method to improve ignitability using methanol which is prospective as an alternative fuel. The constant volume combuster is divided into main chamber and sub-cham¬ber. These two chambers are linked by an adapter which is shaped like a cup. We also compare CDI to HIS that is revised in our laboratory for making a scrutiny into the effects of ignition char¬acteristics. Besides, we analyze a flame propagation process in the main and sub-chamber through taking pictures 10, 000 frames per second by high speed camera at the state being fabricated quartz glass aside main and sub-chamber.

Each of China, Taiwan, Japan and Korea is in international trade one of the major countries in Asia and has been influenced by the Chinese character culture and the Civil law system. All these countries have their own commercial dispute resolution system for international trade dispute and commercial arbitration mechanism in their countries. They are making their own effort to internationalize and improve their commercial arbitration system. Among these countries China enacted a new arbitration law already. At that time Chinese arbitration law was referred to the UNCITRAL Model Law on International Commercial Arbitration for internationalization of Chinese commercial arbitration system. China also internationalized the panel of arbitrators by increasing the foreign arbitrators of the panel of arbitrators of CIETAC. These measures adopted by China will be the model of dispute resolution and the commercial arbitration system in other major countries in Asia.

There are many equipments for the Short Circuit Test, for example Short Circuit Generator, Induction Motor, Sequence Timer, CLR, Back Up Breaker, Making Switch and Excitation Equipment etc. Gradually an allowable tolerance of the short circuit test voltage is become smaller by the standards for short circuit test. The excitation equipment of short circuit generator is very important for test voltage is adjusted by the excitation equipment. Especially the excitation equipment must be possessed character of exactitude, durability and inalterability because some times around 10,000 times opening and closing short circuit test is requested by clint, which must be done within one minute. The purpose of this study for function and operation of the excitation equipment which rated DC voltage is 1,000V, rated DC current is 300A, rated out put is 30kW and type is YNEX 97S-441/609, is to help operation of short circuit generator.

The purpose of this study is to preview artistic presentation, factors of designing and ornamentation, to provide useful information to the wedding dress industry in developing consumer-oriented design of wedding dress. Also, this study is to investigate relativity between individual characteristics, such as demographic character and body figures, and preference of consumers, in order to learn if there is any pattern of consumers decision making, and to help consumers by giving tips for their wedding dress shopping. According to this study, I can see that when modern South-Korean adult women choose their wedding dress, they consider many factors just like silhouette, detail, fabric material and so on, then they select their own best dress by grasping their body characteristics.

Laminated lumber is an engineered wood products using stress rated, seasoned and selected lumber. Each piece of lumber is graded, and then end jointed to produce the required length. This study was carried out to investigate the possibility of wooden artifacts with laminated lumber. It is expected through this research that wooden artifacts, which have originality and local character, can be developed by making design of wooden artifacts through the use of plentiful resources around the local area. A development of new design products, an improvement of distributive structure and the achievement of international competitiveness will contribute to develop the industrial artifacts art in Korea. And, it is necessary to develop a corporation system between industrial craft companies and universities.
