Study on the characteristics Index of soil is a useful in the Engineering of Constraction area by the measure ment of Seismic Waves. This Investigation are determined the Correlation Between Seismic Waves and N value where there are Consolidation Foundotion Beds or Alluvial deposit soil. and the Investigation shames the Following Results. (1) in this Intestigation. Gun San Area Could be Confirmed Consolidation beds as within the N value is 15 (N<15) (2) In this case of Alluvial deposit soil. It appear about 100∼700(m/sec) in limits of S-wates velocity which the caracteristic Index of soil can be measured by the S-waves Velocity. and S-waves velocity Beds are up from 100∼150(m/sec) and 200∼350(m/sec). 300∼700(m/sec) and there could be Confirmed that S-waves velocity was increased as the N value increased in the Alluvial deposit soil.

규모의 비효율성과 요인분해 : 한국컴퓨터 및 관련 산업 Korean Computer and Related Industries

장두영 호남대학교 2004 호남대학교 학술논문집 Vol.25 No.1

This paper is to estimate the production efficiency, technical efficiency and scale efficiency of Korean computer and related industries for 1992-2001 and analyse the key factors of scale inefficiency. The efficiency is estimated by Data Envelopment Analysis. First off, one-fourth or so of the companies in Korean computer and related industries realized an optimum scale production, their scale efficiency ranging from 1.000 to 0.995. The most inefficient company showed a scale efficiency of 0.822. Next, the annual aspect of returns to scale was various. The year when the constant return to scale is carried out is most, while the year of decreasing returns to scale is least. This means that most of companies sometimes produce over the optimum scale or under the optimum scale, realizing an optimum scale production. Of course, there are a few companies that never carried out an optimum scale production during the period 1992-2001. In general, the more is the year of constant return to scale, the higher is the scale efficiency of the company. Finally, the scale efficiency of only five companies were constant or getting higher during the period 1997-2001, compared to the period 1992-1996. This shows that most of them got more and more scale inefficient over time. The factor of scale inefficiency is categorized into three cases. The first one is that the production efficiency decreases, while the technical efficiency is constant. The second is that both production efficiency and technical efficiency decrease. The third is that the production efficiency deteriorates more, whereas the technical efficiency ameliorates. The second category is most and only two companies are concerned with the third one.

Measurement of daily evapotranspiration from Setaria viridis LINNE in the sand area, 1993 often showed quite large values of about 8㎜/day during summer and maximum value was 11.7㎜/day under the high evaporative condition. The weak correlation was obtained between the measured values (ET) and the calculated ones (ETp) using the PENMAN method, because evapotraspiration was greatly influenced by the grass growth condition. Daily evapotranspiration was estimated with a relatively high accuracy by introducing the grass coefficient into the PENMAN method. The leaf area index could be replaced with the number of days often germination from a practical point of view.

This study make a base on proper gradient and slope length on the forest road execution for methodminimum damage make a survey of erosion and sedimentary amountvariation of slope and inclined plane place in area pass 2-3year after forest road execution. This paper purpose accomplishment surveied sample tree maked erosion and sedimentary amount in chungnam province chilgap mountain east, south, north, in three sample forest road 15 place from 6 month to 8 month 1997 year. The results of the this study gradient, slope area, rain, collaps numerical value research list as follow: 1. The forest road research occured collaps cutting slope 8 place, to banking slope 7 place in A, B, C sample all area. 2. The collaps of gradient occur to banking slope ?? , cutting slope ??, The forest road execution have to banking slope ?? below, cutting slope ??, belowslope execution. 3. The slope length collaps occured to all road uncovered slope previous question. The slope length surveied proper 5m below in cutting slope. Putting the abve resuits together, it is thought that foresr toad execution is the most urgent matter method protection of the slope from cutting slope, banking slope. It is require forest road execution in considerstion of the difficulty ofslope recovery short time for minimum proper slope square and slope place.

In this study, in a case of the irregular Time-Distance Curves the analysis method was studied, therefore this method was used for evaluation of dynamic soil parameter in the weathered granite soil. Then, the utilization of the concept of a delay time and the application of phantoming was to evaluate the time-distance for the refracted waves in a measuring line and the depth in the detector point. From the results it was found that how much was Poisson's ratio influenced in the relationship between Vp and E, and Vs and G, and these data related in the correlation between N-values and Vs.

중부지역 고속도로 절토비탈면의 녹화를 위해 시공된 녹화공법과 식생현황분석을 위해, 1995년 3월부터 1996년 2월까지 중부지역의 고속도로비탈면을 대상으로 조사를 수행하였다. 고속도로 절토비탈면의 녹화공법종류는 총 18개 공법이 시공되었으며, 가장 많이 시공된 공법은 종자뿜어붙이기공법(45개소)이며, 다음은 평떼붙이기공법(25개소), 볏짚거적덮기공법(12개소) 순으로 나타나 종자뿜어붙이기공법이 고속도로 절토비탈면 녹화에 이용되는 대표적 공법으로 판단되었다. 노선별 출현종수는 중부선이 243종으로 가장 많았고, 중앙선 223종, 경부선 2구간 210종, 서해안선 199종, 경부선 1구간 179종, 서울외곽선 163종, 신갈안산선 148종, 제 2경인선 141종, 경인선 123종 순이었다. 노선별 식색피복도를 보면 중부선이 가장 높았으며(69.5%), 다음은 경인선(67.8%), 경부선 2구간(66.8%), 경부선 1구간(66.4%), 순이었다. 균재도는 대부분의 노선에서, 상부에서 하부로 내려올수록 감소하는 경향이 있고(6개노선), 종다양도는 경부 1구간(상부종다양도)이 가장 높았으며, 다음은 중부선, 서울순환선, 중앙선 순으로 분석되었다. The purpose of this study was to analyze of structure on vegetation and method for the revegetation on the highway cut-slope in central-area, from March 1995 to February 1996. The numbers of revegetation-measures type surveyed were eighteen measures as a whole in descending order of the Seed-spraying measures, Block-sod pitching measures, Straw-mat mulching measures. The numbers of vegetation species by highway line were 243 in Chungbu, 223 in Jungang, 210 in Kyongbu 2, 199 in Kyongbu 1, 179 in Sohaean, 163 in Seoul circulation, 148 in Shingal-Ansan, 141 in Second kyongin and 123 in Kyongin respectively. The highest of vegetation coverage in highway cut-slope was Chungbu route(66.8%), the highest index of species diversity(H') was Kyongbu 1 line(species diversity of upper) and the evenness(E') on upper site was greater than that of the lower site.
