Department of the imperial guard is of the soldiers organization which is formed in the royal power or the absolute near by a king. Thus, department of the imperial guard absolutely is showed it is a soldiers organization for guard a king. We summary the character and the function as followed when we subdivide. 1. The main mission was the guard of the royal palace. As we know from several historical materials, the defense of the royal palace was an fundamental mission. Therefore, department of the imperial guard would take charge of the defense of the royal palace. 2. They would carry out throne of king and the royal family or a battle. As unification, they would carry out guarding for political stability and a suppress probation of internal war in regard to the security and the frequent rebellion in central and locality. 3. They carried out guarding an honored going of a king or the royal family. We know the fact that there was an honored going of the royal family or many attendants on record. When a king or the royal family go, guarding of department of the imperial guard had not only protect them but also show off the authority of the royal family. As a result, when we analysis the substance from studying the guard system of Shilla, though our guard system is imitated the foreign guard system like U.S.A, transcending space-time, the guard system can be found a lot of something common at the guard principle and a rule. Today, in looking about a political system of any countries on the world, a king and a ruler of the country represent their country international, have responsibility of protect their nation and a people internal. Therefore, the guard for a ruler absolutely must carry out at a safety situation. Moreover the guard organ, at the same time is connected directly to a welfare of the nation, so we will have to devote a constant effort.

The tunnel type spillways is under construction to increasing water reservoir capacity in Dae-am dam. Cutting-slope adjacent to outlet of spillways had been originally designed to be 63 degrees and about 65m in height. Examination is carried out in preceding construction that it is caused to some problems possibility which of machine for slope cutting couldn't approach to the site, blasting for cutting slope might have negative influence on highway and roads nearby, and fine view along the Tae-hwa river would be eliminated. In order to establish stability of tunnel and more friendly natural environment that we are carry out detailed geological surface survey and analysis of slope stability. So, we are design and construct for tunnel excavation with possible method that it is keep up natural slope. The result of survey and analysis that natural slope was divided 3 zone(A, B, C zone). In A and B zone, in first removed floating rock, high tensile tension net is install that it prevent of release and falling of rock, in order to security during under working. In addition to, pre-stressed rock anchor is install purpose of security during tunnel excavation because of fault zone near vertical developed above excavation level. Zone C is relatively good condition of ground, design is only carry out random rock bolt. All zone are designed and constructed drainage hole for groundwater and surface water is easily drain. Desinged slpoe is harmony with near natural environment. Successfully, construction is completed.

This paper analyzed the R&D activities of foreign companies in Korea. A survey was conducted using questionnaires along with the field interviews. The survey results show that some foreign companies in Korea actively carry out R&D indicating that Korea is becoming a R&D location for the multinational companies. It also shows the wide differences by industries, corporate size, foreign equity ratio, and home country of mother companies. It is suggested that Korean government should utilize the inward foreign direct investment to strengthen the national innovation system of Korea. Various policy measures were recommended to encourage foreign companies to have easier access to domestic R&D resources, carry out R&D activities, and interact with domestic R&D actors. It is also argued that it is necessary to eliminate negative environmental barriers perceived by foreign companies.

Important material properties of UCAS rod can divide by tension characteristic of base rod part and both end part of U type anchor. Tensile properties of base rod part need as concrete reinforcement material as an alternative material of reinforcing rod, and tensile properties of U type anchor is used at connection with UCAS rod. This treatise carry out tensile test of UCAS rod, examine necessary properties such as strength, elastic modulus and maximum capacity of UCAS rod as reinforcement material of concrete. Also, to examine material properties carry out tensile test of U type anchor.

In a basic engineering design class, first year engineering department students learn about engineering design relevant theories and carry out simple projects in teams. By doing a group project in this subject, students develop basic skills such as creativity, teamwork, communication, and problem solving. Before, class proceeded in a way where teams were randomly configured in the beginning of semester and students began working on their project immediately. However, this research introduces a new method where at the beginning of the semester, students are assigned group assignments. Teammates are randomly chosen and constantly switched so that students get a chance to work with different people and experience diverse styles and characteristics. Then, they autonomously form into teams with people they work best and carry out their project. We present the behavior of a monkey robot that recognizes emotions as a case of applying the proposed method. The feedback from the students suggest that this proposed team forming method serves to be effective especially since students who were not aware of other students' characteristics can get to know one another better and form a productive team.

DSRC system is a communication system that consists of road side equipment and on board equipment to provide services of communication technology for intelligent transportation systems. In this paper, we carry out a short-range dedicated high-speed wireless communications via DSRC system based on board equipment that is installed in the vehicle and road side equipment through wireless channels of communication. on board equipment is system that have a memory which initialization information is stored, it loads physical layer and MAC layer, LLC layer, L7 layer in turn. In the upper, it should analyze the various commands that are sent from roadside base stations, and carry out the operation which is in accordance with the command. and also it designs the structure of protocol stack which is TRM Layer loaded that is to initialize on L7 layer and MAC layer and efficiently designs operation between on board equipment and the road side equipment.

Purpose: The current education curriculum centering on the national examination can not train the human resources needed for the clinic. Therefore, we would like to develop a curriculum for practical education and cultivate talented people capable of working in clinical practice at the same time. Methods: This study investigates the importance and utilization of the subjects by using qualitative and quantitative mixed research methods through interviews with FGI and structured questionnaires for grades 2,3,4. Results: In order to carry out the related work, all the subjects need more practical training, and the curriculum that can learn the latest prostheses such as CAD / CAM, implant, 3D printer, Conclusion: In order to carry out the related tasks immediately after graduation, practical education through improvement of curriculum is needed.

In this paper, Hadamard transform imaging spectrometers utilizing Grill spectrometers are proposed. General Hadamard Transform Spectrometers (HTS) carry out one-encoding through input masks, but Grill spectrometers carry out double-encoding through entrance and exit masks. Thus Grill spectrometers increase the signal-to-noise ratio by double-encoding. we reconfigure the system by using the Grill spectrometers which use a left cyclic S-matrix instead of the conventional right cyclic one. Then, we model the system and apply the mask characteristics method, i.e. $T^{I}$ method, to complete fast algorithm. Through computer simulations, we want to prove the superiority of the proposed system by comparing with the conventional HTS. From Observations concerning the average mean square error(AMSE) associated with estimates from the $T^{I}$ spectrum-recovery method, the relative performances of the two systems are compared.
