  • The alarming climate change impacts are demanding the use of renewable energy sources like never before. Hydropower is one of the most cost-effective and environmental friendly energy technology recognized in the world. Big hydropower projects come up with the requirements of huge investment costs along with environmental impacts, whereas small hydropower(SHP) are considered a best solution for the economical source of energy. SHP, basically Run-of-River (RoR) type plants can be sustainable renewable energy sources and given the nature of perennial rivers flowing from steep gradient and rugged topography, feasibility of such plants is equally high in Nepal. The objective of this study is to determine the primary potential sites for the development of RoR type SHP sites using Geo-spatial Information System(GSIS). The use of GSIS enables precise survey of large area within a short period of time. This study has focused on the determination of locations by establishing defined criterions and methodologies and hence have located multiple locations rather than selecting one best location. The approach is applicable for the rapid initial screening of potential locations and results can facilitate detail feasibility study for the technical and economic analysis of SHP in the basin.

  • The aim of this study was to characterize the forest vegetation structure and site of Quercus serrata forest for ecological forest management and ecological niche. The results are as follows : The chemical properties of Q. serrata forest soil were 0.24% of total nitrogen, 8.27 of organic matter, 74ppm of available phosphorous, 1.64(me/100g) of Ca, 0.22(me/100g) of Mg, 0.74(me/100g) of K and 9.3(me/100g) of cation exchangeable capacity. The dominant species in Quercus serrata forest were Quercus serrata, Quercus acutissima, Quercus variabilis, Quercus mongolica, Styrax obassia, Fraxinus rhynchophylla and Styrax japonica. DBH analysis showed that Quercus serrata seems to remain as a dominant species for the present because they had random distribution based on few of big individuality, many of small and middle individuality. But the Q. serrata community is competing with Q. mongolica and F. rhynchophylla, whose density of small individuality has increased. With the classification of TWINSPAN, Q. serrata forest was classified three groups, such as Q. serrata-Acer mono, Q. serrata, Q. serrata-Q. acutissima communities. The results of the correlation analysis of Q. serrata major communities and environment factors are as follows; Q. serrata-A. mono community was found relatively in high elevated and eastern and northern area that has relatively high percentage organic matter. Also Q. serrata community was found in high elevated and eastern and northern area that has high percentage organic matter. Q. serrata-Q. acutissima community was found in low elevated and southern and western area that has low percentage organic matter.

  • Finite element analysis along with DOE scheme has been performed to obtain robust design of connecting rod assembly. An analysis was conducted with five loading steps. Fatigue analysis was done using commercial software FEMFAT and fatigue safety factors at the interested regions such as shank area of small end and big end were calculated. 27 design cases using 3 factors with 3 levels are constructed by design of experiment. Each case is simulated to find the most influential factors. Response for this study, maximum Von-Mises stress, has been used to determine main factors of connecting rod assembly. Among the 3 factors, compression load affected the response greatly. However, bolt assembly load and width of shank flat area showed a little influence to the response. Interaction effects among factors considered did not occur. Connecting rod assembly considered in this study showed its sensitivity to the noise factor such as compression load rather than design factor such as width of flat shank area.

  • 본 연구는 수도권 소재 광역쇼핑시설이 기존상권에 미치는 영향을 분석함으로써 광역쇼핑시설을 둘러싼 대·중소 유통갈등의 합리적 해소를 위한 실증적 논거를 제공하고 정책적 함의를 제시하는 것을 목적으로 한다. 광역쇼핑시설은 본 연구에서 사용한 조작적 용어로서 대형마트보다 배후상권 범위가 훨씬 커진 대형 쇼핑시설 유형을 지칭하는 것으로, 하위 유형으로는 초대형백화점, 복합쇼핑몰, 대형패션 아울렛, 창고형 대형마트 등의 네 가지 유통업태를 포함한다. 광역쇼핑시설의 배후상권 특성은 비교집단으로서 대형마트까지 포함하여 다섯 가지 유통업태를 대상으로 분석하였으나, 광역쇼핑시설 출점이 기존상권에 미치는 영향은 네 가지 광역쇼핑시설 업태에 대해서만 분석하였다. 본 연구의 조사방법의 특징은, 특정 점포 단위의 중소상인 대상 설문조사에 의존한 선행연구들과 달리 본 연구는 수도권 내 모든 점포와 모든 소비자를 대상으로 한 설문조사를 활용함으로써 점포 단위가 아닌 지역 단위의 총량적, 평균적 상권영향을 분석하였다는 점이다. 조사분석 결과, 광역쇼핑시설 출점이 약 3%의 총 소비지출 순증효과를 유발하고 있었다. 현존하는 전체 광역쇼핑시설의 업태별 수도권 기존상권 총 잠식률(매출증감률)은 대형백화점 -1.0%, 복합쇼핑몰 -9.0%, 대형패션아울렛 -4.1%, 창고형 대형마트 -8.2% 등이며 이를 합한 전 업태 총합 기존상권 총 잠식률은 -22.2%로 나타났다. 그리고 전 업태 총합의 기존 쇼핑시설 부문별 잠식률은 대규모유통부문 -53.9%, 중소유통부문 -11.0%, 온라인유통부문 +5.7% 등으로 추정되었다. 중소유통부문은 중복산입 가능성이 없기 때문에 현존 전체 광역쇼핑시설의 수도권 중소유통부문 상권잠식률 -11.0%는 합리적인 추정결과로 판단된다. 특히, 광역쇼핑시설 업태별 기존 중소유통부문 상권 잠식률은 복합쇼핑몰이 4.9%, 창고형 대형마트는 5.7%인 것으로 분석되었다.
