  • Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is one of the most destructive diseases of rice worldwide. The rice - M. oryzae pathosystem has become a model in the study of plant - fungal interactions due to its economic importance and accumulating knowledge. During the evolutionary arms race with M. oryzae, rice plants evolved a repertoire of Resistance (R) genes to protect themselves from diseases in a gene-for-gene fashion. M. oryzae secretes a battery of small effector proteins to manipulate host functions for its successful infection, and some of them are recognized by host R proteins as avirulence effectors (AVR), which turns on strong immunity. Therefore, the analysis of interactions between AVRs and their cognate R proteins provide crucial insights into the molecular basis of plant - fungal interactions. Rice blast resistance genes Pik, Pia, Pii comprise pairs of protein-coding ORFs, Pik-1 and Pik-2, RGA4 and RGA5, Pii-1 and Pii-2, respectively. In all three cases, the paired genes are tightly linked and oriented to the opposite directions. In the AVR-Pik/Pik interaction, it has been unraveled that AVR-Pik binds to the N-terminal coiled-coil domain of Pik-1. RGA4 and RGA5 are necessary and sufficient to mediate Pia resistance and recognize the M. oryzae effectors AVR-Pia and AVR1-CO39. A domain at the C-terminus of RGA5 characterized by a heavy metal associated domain was identified as the AVR-binding domain of RGA5. Similarly, physical interactions among Pii-1, Pii-2 and AVR-Pii are being analyzed.

  • The purposes of this study are to investigate the formation and the change of apparel retail structure historically with the viewpoint that the retail structure is affected by the process of economic development. This study was done by literature research method and the result of this study is the following. The tailor and seamstress shops, the first clothing shops in Korea, were replaced by ready-made shops, because mass production system which had developed with the industrialization of Korea increased the advantage of economy of scale compared to handicrafts individual one. After that, the production system of apparel industry had been efficient continuously, while retail system had not. The retailing of famous brand apparel conducted by exclusive franchise store caused supplier oriented markets where the opinion and the desire of consumers were not reflected. While the retailing of the unknown brand apparel handled by small retail stores were inefficient. As the apparel industry matured in 1990s, various types of new stores appeared such as specialty stores, discount stores, TV home shopping, internet shopping, outlet malls, and big fashion stores in Dongdeamoon. These new stores have features of seeking profits in mass merchandising. As these large retail stores grow, the apparel retail structure of Korea is changing from a fragmented market to a vertically integrated one. This change is shown by the decrease of stores per inhabitants. With the change of environment, the apparel retail system which has lagged behind comparatively is expected to develop into more efficient system based on the large capital investment which raise the advantage of economy of scale.

  • Purpose - The purpose of this study is to clarify the difference of store attributes of Korean consumers and to analyze it's influence on consumer satisfaction in duty free stores which gain ground inch by inch in the distribution chanel. And it is to find discriminative result as compared with foreign consumer. Research design, data, and methodology - Subjects for the quantitative study, quota sampling was adopted in the Lotte, Shilla downtown and airport duty free stores from the first to 15th December 2016 and 177 questionnaires from Koreans who had purchasing experience in off line duty free store were analyzed. The data was analyzed by using factor and reliability analysis, descriptive statistics analysis, the independent sample t-test and multiple regression analysis. To test consistency, Cronbach's alpha was used. Results - The result were as follows; 1. Korean consumers consider the importance of store attributes in duty free stores in order Product, Economic Feasibility, Convenience, Promotion, and Accessibility. 2. The meaningful impactive factors of duty free store attributes on consumer satisfaction turned out Product and Promotion. 3. These results show meaningful distinction between Koreans and foreigners in terms of consumer satisfaction in duty free stores. Conclusions - A marketer who is working for duty free store consider now that price benefit can not give strong impact to Korean consumers more and should concentrate on various brand assortment even including private brand. In terms of promotion, most duty free shops put special stress on foreign consumer's wants now as highly increasing of Chinese travelers but Korean consumer's sales portion and number of visitor also are steadily increasing. Therefore, a duty free marketer should prepare the Korean-oriented services with more enhanced promotion strategies for individual and group travellers, for example, a mileage service, VIP room and social network system to satisfy Korean consumers. In order to get satisfaction from Korean consumers, it makes effort on product and promotion than accessibility, price and convenience. Due to high level influence, further study is needed to enlarge to on-line market and to develop private brands for duty free stores.

  • Pediatric surgeons are familiar with the posterior sagittal approach to the rectum at sacrococcygeal area and well oriented with the anatomy because of the Penal procedure for imperforate anus. The author utilized the posterior vertical elliptical incisions in 12 cases of sacrococcygeal teratoma since 1987. For presacral tumor(type IV)$^2$, the incision was exactly same as the posterior sagittal procedure for imperforate anus. But the out-growing(type I) or dumbbell-shaped(type II & III) tumors, a vertical elliptical incision was required. For the laterally deviated tumors, a vertical and half-chevron incision was utilized in one case, but an unbalanced vertical elliptical incision was acceptable for the remaining two cases, with shrinkage of the overlying skin. In dumbbell-shaped tumors(type II & III), the narrow waist of the tumor was at the level of the levator muscle, which formed a muscle-belt on the tumor waist. A careful dissection to save the muscle-belt seemed to be the most important point during this procedure, utilizing the nerve-stimulator. After complete removal of the tumor and the coccyx, the levator muscles and the skin were closed in vertical fashion along the midline. For the caudally extending tumors in 3 cases, the muscle complex was divided in midline. Nothing by mouth and total parenteral nutrition was maintained for 1 week and then laxatives were given for 2 weeks in order to give the sphincters rest. Operative scars were acceptable resembling natural vertical midline folds, and the sphincter function was continent in all cases. In conclusion, vertical elliptical incision in sacrococcygeal teratoma is recommended because of the acceptable scar, functional restoration, and because it is a familiar procedure particularly for the pediatric surgeons who are accustomed performing posterior sagittal approach for imperforate anus.

  • Global sourcing strategy is the one that apparel firms adopt in order to improve efficiency. Souring statesgies are not limited to the decision of sourcing country or vertical integration of sewing process Sourcing strategies include all the ecision of marketing process from the acquisition of fabric to distribution of products. The present study aims to analyze the soucing strategies of Korea apparel industry in global perspectives by applying transaction cost approach and aims to provide the implications for the future. The results are as follows ; (1) sourcing strategies in the dimension of domestic versus offshore soucing are determined by the experience in foreign business and the degree of fashionability of the product. (2) Firms tend to increase affshore soucing as they accumulate the experience in foreign business because they can decrease transaction costs as the perceived risks decrease (3) Also firms tend to source their products in foreign countries when the products are more fashionable. Brand loyalty of the product is a additional factor that increases the proportion of domestic sourcing. (4) Degree of vertical integration of sourcing is determined by the fashionability brand loyalty and the experience in foreign business. That is firms decrease the transaction costs by avoiding the investment to short life fashion products. However firms increase the control over the high reputation product by in house production. As the apparel firms tend to more marketing oriented and the national boundaries of business envrionment becomes permeable more efficient global sourcing strategies should be stablished, Besides the production costs nonproduction costs should be equallly considered in order to analyze the total costs.

  • In this study, hyperspace is a result of imagination created by means of facts and fiction, represents a transfer to determination and indetermination, and means an extension to an open form. In other words, hyperspace is a high dimensional space expanded to imagination through the combination of the viewpoint on facts in this dimension and fiction. When the 2D plane surface or 3D symmetry is destroyed, or when the frame is twisted or entangled, the non-Euclidean geometry is created eventually. And when the twisting leads to transmutation and the destruction of the form reaches the extreme; this in turn became the twisting like Mbius band. Likewise, the non-Euclidean geometry is co-related to the asymmetry of the Higgs mechanism. When the 'destruction of symmetry' is considered, symmetric theory and asymmetric world can be connected. The asymmetry in turn can maintain balance by arranging the uneven weights at different distances from the shaft. Moreover, at this the concept of the upper, lower, left and right, which was included in the original form, may be crumbled down. The destruction of the symmetry is essential in order to present forecast that coincides with the phenomenon of the real world. Non-Euclidean geometry characteristic is expressed by asymmetry, twists, and deconstruction and its representative characteristic is ambiguity. The boundary between the front, back, upper, lower, inner and outer is unclear, and it is difficult and vague to pinpoint specific location. The design that does not clearly define or determine the direction of wearing costume is indeed the non-oriented design that can be worn without getting restricted by specific direction such as front and back. Non-Euclidean geometry characteristic of hyperspace have been applied to create new shapes through the modification of the substance from traditional clothing of the eastern world to modern fashion. The way of thinking in the 'hyperspace' that used to be expressed in the costumes of the east and the west in the past became the forum for unlimited creation.
