The purpose of the research is to let people recognize the necessity of Karatedo training and enhance the value of it. Karate sparring is quite helpful to learn the skills that how to escort a protectee as a guard. The skills are divided into hand skills, foot skills and pitching skills. Firstly, it is the hand skills. 'ap-son-chi-gi' or 'di-son-chi-gi' at pressure points such as face, neck and abdomen is effective to overpower adversary. If straight attacks are not easy, 'return stroke' is better. Secondly, it is the foot skills. Front kick towards pressure points, straight attacks like side kick and hindpaw kick and curving attacks like front-spinning kick, 'ap-hu-ri-gi and 'di-hu-ri-gi', these are different types of the foot skills. Lastly, it is the pitching skills. To overpower compeletly, tripping up and 'hu-ri-gi' for breaking the balance and then hand and foot skills for attacking the pressure points are the best way.

This paper aims to explore the characteristics of regional embeddedness of Korean firms in Daren City, China, with special reference to management practices. To achieve this goal, I attempt to analyze the type and structure of the firm, the structure of decision-making, labor practices, and the inter-organizational networks with the government, trade associations and the business supporting agencies. The major purpose of the investment in Daren by Korean firms is to penetrate and expand the local market. In line with this, the structure of decision-making by Korean firms tends to become increasingly autonomous, especially in terms of employment and marketing. However, the decision-making related to finance and accounting tends to be still highly controlled upon the headquarter in Korea. In addition, it is shown that Korean firms make a great effort to sustain the cooperative relationships with the local society and the local government.

This paper analysed the architectural images on Pleasant Gathering of Leeum, Samsung museum of art, which has been assumed as a work of the Koryo dynasty. Through the comparison between the unique wooden structure at roof edge on the building images and real architectures, it found the buildings on the painting were from China Fujian(福建), not from Korea. It also analysed the color painting on buildings, trees, themes from previous famous paintings and dresses to confirm these images were came from the early period of the Ming dynasty. It is a very unique painting containing various information on the Fujian ancient architecture, but its architecture drawing is not as skillful as typical ancient Chinese paintings.

Since China's economic reform in 1978, international trade has enormously flourished and the port industry is reckoned as a key factor contributing to this growth. This study examines the Bohai Rim port group in the scope of top three largest ports Qingdao, Dalian and Tianjin. By utilizing indicators including concentration ratio (CR), Herfindahl-Hirschman index (HHI), the Gini coefficient and the Lorenz curve as well as shift-share analysis (SSA), the concentration level of this port group in the period 2004-2016 is discussed. As a results, CR demonstrates a decrease during the studied period with a minor fluctuation, and HHI index shows a trend of deconcentration with Bohai Rim port group. In addition, SSA indicates that during the period 2004-2016, the overall shift index of Qingdao port was -1.371 meanwhile with Tianjin and Dalian port were 0.118 and 1.252 in turn. These results suggest that the growth in regional influence of Tianjin and Dalian ports would motivate to the deconcentration pattern in Bohai Rim region. The findings assist decision makers and scholars to obtain knowledge about the port development this region. Considering the geographic position of these three ports as the gate of northeast China, it is suggested that these three ports could explore their advantages and cooperate with the small ports in the surrounding area to enhance their influences in the future study.

The nucleotide sequences of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene of octopus groups collected from Muan, Taean, Yesu, Jeju in Korea and Youngsung, Daeryen in China were analyzed for the identification of species and populations. Six haplotypes were identified from the analyzed 60 individuals. All of the individuals (N = 10) from Jeju showed the A haplotype which was not observed from other groups, and could be classified as a distinct group. The analyzed groups could form two separate clade in MEGA4 analysis. The individuals from Muan, Taean, Yesu in Korea and Daeryen in China form a clase and the others from Jeju in Korea and Youngsung in China formed the other clade. The analysis of relationship among the groups showed the same results. Individuals belong to the group A (Muan, Taean, Yesu and Daeryen) showed closer relationship than individuals belong to the group B (Jeju and Youngsung). Although the CO1 universal primers used in this study was useful as a marker for species identification among Octopus, analysis of population was limited because of few variations in the partial sequences of CO1 analyzed in this study. However, it was possible to show the limited gene flow among the groups which is resulted from the spatial separation and differences in their habitats.

This research is aimed to analyze the basic characteristics of the 16 floor plans of 4 small-sized apartments in DaLian-City. Recently, there are increasing that a small-sized apartments for new younger generation in China. The younger ages intend to got a new floor plan types apartments according to own's life style. Also, a lot of construction company showed the many types of new residential space design during the last about 10 years, in DaLian City. The research results are summarized as follows: First, all of the floor plan types were '-' shape, 'L' shape. Second, there were several co-relational types of space plan between living room, kitchen and dining space. Those are LDK, L K, L DK, LD K. Third, the bedroom of the $30m^2$-floor plan size has an open-space design but over the size of $40m^2$-floor plan the space is closed design. Fourth, The number of bathrooms in all the floor plans is just 1 and it's placed beside the entrance except for B3, C4. The basic equipments of the lavatory was a toilet, a washbowl, a shower. A bathtub is installed in the floor plans greater than $60m^2$. Fifth, almost all of the characteristics of the spatial interrelation - each room position order - based on the location of the entrance. In particular, almost all of the bedrooms are furthest from the entrance for the most privacy.

Ferromagnetic Mn-Al nanoparticles were prepared using a plasma arc discharge method. The influence of the process parameters on the vaporization rate, composition, particle size, and magnetic properties of the as-produced nanoparticles was investigated. The Mn content was found to be higher in the nanoparticles than in the corresponding mother materials, although the difference diminished with the reaction time. As the $H_2$ content in the reaction gas increased, both the vaporization rate and the particle size increased. With 30 at.% Mn, the average particle diameter was 35.2 nm under a pure Ar gas condition, whereas it was 95.4 nm at a Ar:$H_2$ ratio of 60:40. With the addition of a small amount of carbon, ${\varepsilon}$-phase nanoparticles were successfully synthesized. After a heat treatment in a vacuum for 30 min at $500^{\circ}C$, the nonmagnetic ${\varepsilon}$-phase was transformed into the ferromagnetic ${\tau}$-phase, and a very high coercivity of nearly 5.6 kOe was achieved.
