The objective of this study was to develop allometric equations and stem density and biomass expansion factor for Pinus rigida stands in Muju region. The coefficient of determination of the allometric equations in independent variable (dbh) and dependent variable (biomass) was more than 95% with the exception of leaf (78%) and branch(83%). The total biomass was $102Mg\;ha^{-1}$ ($65.9 Mg\;ha^{-1}$ from stem wood, $9.5Mg\;ha^{-1}$ from stem bark, $19.6Mg\;ha^{-1}$ from branch and $7.0Mg\;ha^{-1}$ from leaf). Biomass distribution ratio of Pinus rigida stands showed the highest in stem wood with 64.6%, followed by the branch with 19.2%, stem bark with 9.3% and the leaf with 6.9%. The results indicated that the stem density $(g/cm^{3})$ and the biomass expansion factor were 0.453 and 1.344, respectively.

This paper discusses the types and functions of English subordinate clauses, whether English subordinate clauses (SC) are headed by a Complementizer (CP) or headed by a lexical (but not functional) Preposition (PP). Furthermore, unlike the standard classification, the current paper provides a finer-grained analysis and classification of English SCs. The traditional or prescriptive view on the functions of English SCs includes Noun SC such as complement clauses, Adjectival SC including relative clauses, and Adverbial SCs that cover a garden variety of subordinators. Added to the existing classification of subordination in English is what I notate as Verbless subordinate clause (V-less SC). Of these 4 different types of subordinate clauses with different functions, properties, and distributions, Subjectless Verbless subordinate clause is further divided into Smallest small clause (SSC) which accounts for English subordination mechanism more uniformly and consistently with respect to their clausal architecture, especially when the subordinate clause is neither PP nor CP.

This study investigates what influences the 2030 households' intention to utilize housing support policies for the younger generation. Using the logistic regression model, our empirical results show that the 'the recognition of youth housing support projects', 'the housing occupation', 'employment type', 'housing type', and 'age' factors have a significant effect on the intention to use the housing support policies. Specifically, the intention is positively associated with economic activity, one-room residence, monthly rent, employment status during the Covid-19 period, and policy recognition, while negatively related to age. In addition, willingness to use the housing support policies is greater when respondents lived in a studio, lived on a monthly rent, recognized the policy, and improved their employment status. The results suggest that housing support programs need to be expanded and improved. Moreover, information on housing support policies should be efficiently delivered to eligible households, and more sophisticated housing support policies should be provided for young people early in their careers.

비신호교차로 사고를 대상으로 신호기 운영방법과 차로폭에 따른 고령운전자 교통사고 특성을 파악하기 강화군, 무주군, 원주시, 보령시의 3년간(2007년-2009년) 교통사고 데이터를 사용하여 일반운전자와 고령운전자의 사고를 비교, 분석하였다. 그 결과, 고령운전자 교차로 교통사고는 점멸신호기로 운영되는 교차로사고는 일반운전자보다 다소 높았으며, 정면충돌사고 일반운전자 사고의 8배나가 높게 나타났다. 또한 고령운전자 교차로 교통사고는 차로폭이 6m초과 13m이하의 교차로에서 41.0%가 발생하여 왕복 3-4차로에서의 교차로에서 고령운전자의 교통사고 발생률이 높은 것으로 나타났다. 따라서 고령운전자의 교차로 교통사고 예방을 위해서는 6m초과 13m이하의 도로에 대한 대책이 마련되어야 할 것이며, 점멸신호기로 운영되는 교차로에 대한 점검이 필요하다.

자판기 생산업체가 없어 전량을 수입에 의존하고 있는 러시아 모스크바를 중심으로 자판기 설치가 대중화되고 있어, 향후 최고의 비즈니스 아이템으로 부상하고 있다. 러시아에서 다수를 차지하는 자판기 정류로는 커피자판기와 캔자판기로 95% 이상이 모스크바에 집중돼 있는 것으로 나타났는데, 모스크바의 경우 자판기 설치대수는 유럽의 5%에 불과하며, 자판기 1대가 약 1,600명꼴로 보급이 되어 있는 반면, 유럽은 1대당 평균 134명 꼴로 보급되어 있는 것으로 나타나 향후 전망이 매우 밝은 것으로 예상된다. 전문가들에 의견에 따르면 러시아 자판기 시장 잠재력은 매우 커 향후 5년간 자판기 판매 금액만 연간 1억 4000만달러, 자판기를 통한 음료수 판매액은 연간 10억달러에 달할 것으로 전망하고 있다. 한편 러시아에 수입괴고 있는 자판기 대수에 대한 정확한 수치는 나와 있지 않지만, 수입통계 및 전문가들의 의견을 고려해 볼 때 모스크바에만 약 5000대의 자판기가 설치돼 있는 것으로 추정된다. 그러나 이들 자판기중 30%는 코카콜라가 제공하고, 10%는 네슬레사, 그리고 펩시콜라, TetraPak사 등이 공급한 것으로 나타나 일반적인 자판기 시장의 확대 여지는 큰 것으로 분석되고 있다.

This paper is mainly forcused on the application of modal analysis In analyze the geometrically non-linear buckling behaviors of large span spatial structures, and the evaluation of each eigen mode affected post-buckling behaviors and buckling loads. Modal analysis is applied . to derivation of the system matrices transforming actual displacement space into generalized coordinates space represented by coefficients multiplied in the linear combination of eigen modes which are independent and orthogonal each other. By using modal analysis method, it will be expected to save the calculating time by computer extremely. For example, we can obtain the satisfactorily good results by using about 7% of total eigen modes only in case of single layer latticed dome. And we can decrease the possibility of divergence on the bifurcation point in the calculation of post-buckling path. Arc-length method and Newton-Raphson iteration method are used to calculate the nonlinear equilibrium path.

There are human casualties that caused by slope-stability related disasters such as landslide and debris flow during typhoon and rainy season every year in Korea. These disaster sites can be analyzed systematically using digital topographic data and aerial photogrammetry. In this study, geographical factors such as slope degree, geology, height, and soil depth are analyzed in four landslide-disaster sites from Muju, Jinan, and Jangsu County based on digital elevation maps generated by ArcGIS. Each site showed different characteristics in geology and geography and it is found that GIS can be utilized for the visualization of steep-slope failure areas.

Natural stress measurements have been made at two sites at the depth of 280m from surface by means of stress relief overcoring methods using three directonal deformation gage. Attempts have been made to determine the state of natural stress in the rock and provide useful basic data to investigate the stress distribution and the determination of yield zone around powerhouse cavern. The magnitude and the direction of the miximum principal stress obstained from in-situ stress measurements is -96.1kgf/$\textrm{cm}^2$ and N38$^{\circ}$W, N35$^{\circ}$W respectively. Vertical stresses are in approximately agreement with the theoretical value. The ratio of measured to theoretical stresses are 85% at two sites. The ratio of average horizontal to vertical stresses(k=($\sigma$h)ave/$\sigma$v is 1.07.

Geochemical and Sm-Nd isotopic results are reported for amphibolite of the Muju area, Ryeongnam massif. Major and trace element data analyzed indicate that the parental rock of the Muju amphibolite is tholeiitic basalt. The Sm-Nd amphibole-WR-plagioclase data define an isochron corresponding to $1766{\pm}121Ma$ ($1{\sigma}$) (MSWD=1.10) with an initial ratio of $0.51032{\pm}15$. We interpret this age as a metamorphic age of the Muju amphibolite. Tectonic discrimination diagrams clearly fail when they are applied to the Muju amphibolite probably due to compositional variations resulting from crustal contamination and/or degrees of partial melting.
