  • 은은 주조성과 가공성이 뛰어나 장신구 제작에 주된 소재로 채택되어 왔다. 이런 은 소재 자체의 장점을 이용한 전통적인 방법 중 하나인 모꾸메가네는 나뭇결무늬와 같은 자연스러운 금속의 혼합문양을 표현할 수 있어서 부가가치가 높지만 제작 공정이 복잡하고 힘들어서 경제적으로 장신구를 제작하는데 어려움이 있었다. 기존의 모꾸메가네 공정 대신 은과 구리의 융점차를 이용한 변형 주조 방법과 냉간압연으로 구리와 은 두 금속간의 우수한 결합을 유지하면서도 기존의 모꾸메가네와 유사한 표면 장식 효과를 얻을 수 있는 새로운 공정을 제안해 보았다. 직경 3 mm의 구리 그래뉼과 0.5 mm, 1.5 mm 두께의 구리 판재에 순은 용탕을 부어 두 금속간의 확산 접합이 완성된 괴를 만들고, 이후 롤러 압연을 실시하여 두께 1.5 mm의 판재를 만들어서 이를 이용하여 반지 시제품을 제작한 결과, 제안된 공정으로 이종 금속 접합도가 우수하면서 모꾸메가네와 유사한 효과를 성공적으로 낼 수 있었다. 제안된 공정은 기존의 반복된 열간 가공에 의한 복잡한 모꾸메가네 공정에 비해 보다 간단하고 경제적으로 모꾸메가네 효과를 갖는 은 장신구 디자인을 가능하게 함을 확인하였다.

  • The objective of this study was to conduct the species identification and tree-ring dating of Lotus Pedestal of the Amitabha Statue at Ssangbong-Temple in Hwasun. The six wood blocks used for the Lotus Pedestal were hard pines (Pinus spp.; diploxilon) except one piece which was ginkgo (Ginkgo biloba L.). The lotus leaves surrounding the pedestal body were also made of ginkgo. Tree-ring patterns of 3 blocks were synchronized and a 133 years chronology was made. The chronology was crossdated well with the master chronology of Japanese red pine in South Korea. It dated back to A. D. 1551~1683, i.e. the last ring dated A. D. 1683. Through the estimation of the number of sapwood rings removed during carving, the felling year was calculated A. D. $1704{\pm}10$. The calligraphic writing on the Pedestal indicated that this statue was made in A. D. 1694. Therefore, the accuracy of the tree-ring dating has been proven.

  • The most important issue of today in design genre is the comprehensive design that overcomes the limitations of the rational and logical designs of functionalism that has had influences in entire 20th century and encompasses even the emotional aspect of humans. The emotional design factors in furniture designs will be analyzed in order to analyze their effects and values on the consumers of present times. The emotional uses of the patterns with the motive of nature expressing papers, flowers, wood textures, natural phenomena etc as they are and the colors with the vivid feeling of primary colors represent more dynamic and cheerful life style and the designs are characterized by the warm primary colors that give the feeling that the nature has been transferred to the designs as it is. Diverse materials such as leather, fur, fabric and the materials with soft and flexible feeling such as silicone material have been used more widely and they are used as the materials expressing freedom not being formalized. The designs that can produce diverse spaces desired by users by gathering unit modules can be said to be the outcome of the emotional designs combined with the needs of modern peoples that aspire their own designs.

  • To determine geographical patterns of natural parasite infections among wild rodents, a total of 46 wild rodents from 3 different localities in northern Gangwon-do (Province), Korea were examined for intestinal parasite infections. Along with nematodes such as hookworms and Syphacia spp., Plagiorchis muris (2 specimens) (Trematoda) were collected from striped field mice, Apodemus agrarius. In a Korean wood mouse, Apodemus peninsulae, the overall nematode infections were similar to A. agrarius, but an adult worm of Echinostoma hortense (Trematoda) was collected. In addition, 2 species of cestodes, i.e., Hymenolepis nana and Hymenolepis diminuta, were collected from A. agrarius. Through this survey, A. agrarius and A. peninsule were confirmed as the natural definite hosts for zoonotic intestinal helminths, i.e., P. muris, E. hortense, H. nana, and H. diminuta, in northern Gangwon-do, Korea. Considering increased leisure activities around these areas, seasonal and further comprehensive surveys on wild rodents seem to be needed to prevent zoonotic parasite infections.

  • The study aimed to find the fundamental differences of aesthetics in Korea, China, and Japan by analyzing expressive features and structural meanings of the storage furniture from $17^{th}$ to $19^{th}$ century. The study was performed in four steps; analysis of expressive features, isotopic analysis, semantic structure analysis, and comprehensive interpretation. The results showed that three countries had linear shapes with curvilinear elements, closed forms with open spaces, natural material hues with change of tone or color, and symmetrical forms with asymmetrical patterns and structures in common. Korea comparatively accented on the natural material colors and wood grains. China stressed on the big and wide faces using three-dimensional carving. Japan accented on the linear elements with strong color contrast and decorative metal fixtures. These features were caused by the traditional thoughts and according aesthetic principles. Korea and China were affected by the Confucianism focused on establishing the order of rank. Meanwhile, Japan was more influenced by the Buddhism emphasized on the individuality and communication. Therefore, the differences of the expressive features in furniture among the three countries were inevitable consequences of the different ideologies.

  • Pine wilt disease (PWD) is one of the hazardous pine tree diseases in whole world. In Korea, PWD has been spreading since it was first observed in Busan in 1988. Dispersion of PWD is mainly mediated by its vectors such as Japanese pine sawyer. In this study, we characterized environmental condition including meteorological factors, geographical factors, and land use factors influencing on the occurrence of PWD. The occurrence data of PWD were collected at 153 sites where were the initial occurrence sites of PWD in local government regions such as city, Gun, or Gu scale. We used Akaike Information Criterion (AIC) to evaluate the relative importance of environmental variables on the discrimination of occurrence or absence of PWD. The results showed that altitude, slope, and distance to road were the most influential factors on the occurrence of PWD, followed by distance to building. Finally, our study presented that human activities highly influenced on the long term dispersal of PWD.
