  • This study was conducted to classify quality attributes for quality elements of public service targeting Gochang Jayeonmadang and analyze their impact on resident satisfaction and dissatisfaction by each service quality element by using the Kano model and the customer satisfaction coefficient and dissatisfaction coefficient of Timko(1993). As a result of the study, all 20 quality elements of public service were classified as one-dimensional attributes. Since the Jayeonmadang project restores the damaged natural environment and restores the ecosystem, it is judged that satisfaction is proportionately satisfied as the natural environment has been restored and the ecosystem has been restored. According to Timko (1993)'s analysis of customer satisfaction coefficient, it is believed that the most effective way to improve residents' satisfaction is to carefully establish and implement maintenance plans and to create a good environment to ensure that plants have settled.

  • A stabilizer link connects the stabilizer bar to the lower arm of the suspension. When a vehicle is turning, lateral forces from the tire are transmitted through the stabilizer link into the stabilizer bar. The stabilizer bar will twist, thus adding rigidity to the vehicle body. In this study, the stabilizer link body was manufactured by using composite material with POM-GF25%. Therefore, the strength evaluation of stability link body with composite material carried out from tensile, wear and fatigue test. The tensile strength between the stability link body with composite material and the rod with knurling was the largest of four types of rod. In Analyzing materials property using optical sensing technique of stabilizer link for automobile parts, its has been identified the safety.

  • 스태빌라이저는 선박, 자동차 및 비행기 등에서 과도한 동요를 막고 자세를 안정시키는 장치를 말한다. 본 연구에서 스태빌라이저 링크 POM-GF25%인 복합재료와 금속을 사용하여 제조하였다. 스태빌라이저 강도 평가를 위하여 인장, 압축 및 볼스터드 빠짐으로 실시하였으며, 모두 기준을 만족하였다. 4가지 형태의 로드에서, 널링된 로드가 가장 큰 강도를 나타내었으며, 금속제를 대체할 수 있을 것으로 판단된다. 또한 사출 금형의 재해석으로 스태빌라이저 링크 본체의 형상을 개선하였다.

  • Lumazine protein은 lux operon의 하류 영역에 존재하는 riboflavin synthase와 아미노산 상동성을 보일 뿐만 아니라, riboflavin synthase의 기질인 6,7-dimethyl-8-ribityllumazine (lumazine)과 결합하여 청록색의 형광을 내게 하는 형광 단백질이다. 발광세균 Photobacterium phosphoreum의 lumazine protein을 코드하는 유전자의 염기서열을 결정하였는데, 이 유전자는 lux operon의 656 bp 상류의 영역에 존재하며, lux operon과는 서로 반대 방향으로 전사되는 것으로 나타났다. 중합효소 연쇄 반응(PCR: Polymerase Chain Reaction)의 방법으로 아미노-말단 절반 lumazine protein을 코드하게 되는 유전자(lumP-N)를 클로닝하여 형질전환의 방법으로 대장균에 유전자를 전이시켜 이들의 유전자의 발현 양상을 조사하여 보았는바, lumP 전체 유전자(lumP-W)가 삽입되어 있는 재조합 플라스미드에서는 발현이 매우 미약한 반면에 아미노 -말단(lumP-N)이 들어있는 경우는 과발현됨을 보였다.

  • This study was conducted to prioritize land purchase in Hwapocheon wetland protection area by reflecting the conservation value of wetlands considering HSI(Habitat Suitability Index) for flagship species. As a result of this study, the flagship species, Oriental White Stork and Been Goose, which can represent the Hwapocheon wetland protection area, were selected through selection criteria and expert feedback. Based on the habitat requirements of the selected flagship species, SI(Suitability Index) for the flagship species was reviewed and the conservation value of wetlands was assessed. The conservation value of the wetlands was divided into five grades from very high to very low. The areas with high conservation value were mainly distributed around wetlands and waters in upstream and downstream of Hwapocheon wetland protection area. The land purchase priorities were divided into five grades by overlapping the thematic maps of the conservation value of wetlands, the economics, and the urgency of restoration. The arable lands which can disrupt wetland ecosystems are analyzed as priority areas where priority purchasing is required. Relatively well-preserved wetlands and areas have low land purchase priorities. This study is meaningful in that biodiversity is considered in land purchase priorities.
