This study area show the complicated geological figure and some developed small fault area in southern of Korea. Because of insufficient investigation and design for the big slope, even the safety analysis by the specific institution, in the event, there were 6 times failure and 6 time safety analysis. After all, The height and remedial work cost of the slope became much bigger then early stage.

The paper addresses the suitability of wind pressure coefficients specified in contemporary design standards and codes of practice for gable roofs of intermediate slope (roof angle $10^{\circ}-30^{\circ}$). In a recent research study, a series of low building models with different roof slopes in this intermediate range were tested in a boundary layer wind tunnel under simulated open country terrain conditions. This was different from the original study in the 70's, which produced the current provisions on the basis of a model tested only for a single roof slope (4:12) in this range. The results of the study suggest that a modification to the American wind provisions would be warranted to make them more representative of the true local and area-averaged wind loads imposed on gable roofs of intermediate slope.

In this paper, a review on second order slope rotatable designs (SOSRD) is studied. Further, different methods of constructions of SOSRD like slope rotatable central composite designs (SRCCD), SOSRD using balanced incomplete block designs (BIBD), SOSRD using pairwise balanced designs (PBD), SOSRD using partially balanced incomplete block type designs (PBIBD) and SOSRD using symmetrical unequal block arrangements (SUBA) with two unequal block sizes are examined in detail. A table is provided where for a range of different values of v (v stands for number of factors) the design points needed by different methods are compared. The optimum SOSRD with minimum number of design points for each factor is suggested for $2{\leq}v{\leq}16$.

Test application of revegetation measure was made on the roadside slope damaged by Gimcheon-Eomo national road improvement project in a bid to prevent the soil from being washed out as well as to restore the ecological environment, and the survey for assessing the effect of slope revegetation measures was conducted, beginning Sep 7 through Sep 20, 2006. In the wake of comprehensive reviewing and evaluating the surrounding topographic environment, physical and chemical characteristics of soil, germination of revegetation plants, analysis of bio mass, covering ratio and the plants appeared, revegetation measure C was found to have been most effective and desirable for further application in the area. Viewing the specific applicability by the area, revegetation measure C and C-1 appeared to be appropriate for blasting rock slope and ripping rock slope as they are efficient in preventing the slope from being washed out and in early revegetating. And revegetation measure B deemed to be effective to blasting rock slope or ripping rock slope as an alternative. And for cut slope, vegetation measure C-2 was judged to be more effective than measure D or E, while measure C-3 would be appropriateto embankment slope.

The abrupt failure of slope caused by a concentrated rainfall would be a disaster in this country. Specially, the soil slope may be collapsed by the rainfall seepage, however, there is not much information for the mechanism of slope failure during rainfall. As analyzing the stability of slope by rainfall, the conventional method is to put the ground-water level on the surface of slope. However, it may provide the over-reinforcement for the slope stability. Futhermore, although over-reinforcement for the slope was fulfilled, the possibility of potential slope failure still exists. In this study, the slope stability by the conventional design method and the causes of unstable slope during rainfall were investigated. To analyze the slope stability by rainfall, the computer program SEEP/W for the analysis of seepage was used. As changing the intensity and duration of rainfall in SEEP/W, the analysis were performed. After completion of analysis, the porewater pressure data from SEEP/W was applied to SLOPE/W. As a results of this analysis, it is not reasonable that the groundwater level is going up to the surface of slope during rainfall. Therefore, the conventional reinforcement for the slope stability is not obvious to satisfy the criterion safety factor during rainfall. The reasonable counterplan is to install drainage hole on the surface of slope in order to prevent erosion and debris flow.

강우시의 비탈면 설계에서는 강우특성변화에 따라 지하수위가 지표면에 위치하는 것으로 가정한다. 또한, 안정성 검토는 비탈면 설계시 대절토 비탈면을 대상으로 수행하는 반면, 안정성 검토가 수행되지 않는 비탈면에 대해서는 설계기준에 규정된 표준 경사가 적용된다. 강화된 지하수위 적용기준에도 불구하고 강우시 비탈면의 규모와 관계없이 비탈면 붕괴가 지속적으로 발생되고 있다. 붕괴원인을 조사하기 위하여 본 연구에서는 지반 조건별로 건기시와 우기시에 대하여 국내 시방기준에서 제안하고 있는 토사 비탈면의 표준경사에 대하여 안정성을 검토하였다. 시방기준에서 제시된 비탈면 표준경사는 건기시나 우기시 모두 안정해야 함에도 불구하고, 검토 결과는 많은 경우에서 기준 안전율이 얻어지지 않는 것으로 나타났다. 건기시의 경우는 전체 검토대상 조건에 대하여 약 50% 이상, 우기시의 경우 약 65% 이상이 기준 안전율을 만족하지 못하였다. 이러한 결과를 바탕으로 본 논문은 현 설계기준의 문제점을 지적하고 대책수립을 위한 방안을 제안하고 있다.

1995년 일본 고베 대지진 발생 이후 한국정부는 국내 시설물에 대한 내진설계분야 및 지진피해 최소화 방안에 대한 연구를 지속적으로 진행해왔으며, 현재까지 괄목할 만한 많은 성과를 내고 있다. 그렇지만, 국내비탈면과 같은 구조물들은 여전히 내진설계가 적용되지 않고 있으며, 일부 기관에서만 설계자의 판단에 의해 비탈면 내진설계가 적용되고 있는 실정이다. 본 연구에서는 국내외 비탈면 내진설계에 대한 연구 결과를 소개하고 국내비탈면에 적용할 수 있는 내진설계 방안을 제시하였다. 비탈면 내진설계 적용범위는 경제성, 비탈면의 중요도 및 복구의 용이성 등을 고려하여 공학자가 내진설계 여부를 판단하도록 하는 것이 바람직하며, 우리나라 비탈면의 내진설계 적용 범위 및 관련 기준도 지진관련 자료를 축적하여 향후 단계적으로 정립하는 것이 바람직 할 것으로 판단된다.

This study aimed to evaluate how users are satisfied with village community center. It will develope and determine a most detailed design and requirements to maximizing for user's convenience. The study conducted interview survey using questionnaire based on universal design principles, to users of village centers that are in possible of cooperation of 25 village centers in Haw Soon district, Jeonnam province and used 160 cases to the analysis. The conclusion of this study is as follows. First, users showed most satisfaction about LDK space and dissatisfaction about design, stair/slope, entrance, and bathroom. Specially, users are dissatisfied with curtains at room and handralis at entrance. In terms of design, users about the indoor-outdoor environment as a whole was unsatisfactory. Second, survey on actual needs space scrutinized bathroom, kitchen, and stair/slope according to priority. In result of these surveys, user's satisfaction with village community center and actual needs space show needed improvements on bathroom and stair/slope space urgently.

조경설계에 있어 디자인 원리에 대한 정량적 연구는 설계가에게 매우 중요한 데이터로써 본 연구에서는 옥산서원의 경사지에 수평으로 올라가는 담장의 리듬을 디자인 원리로 분석하여 리듬에 대한 구체적인 비례와 수열을 분석해 내고, 이를 모티브화 한 다음 설계에 응용할 수 있는 설계방법론을 제시하였다. 옥산서원은 매우 가치있는 문화재로서 담장의 경사지리듬에서 비례와 척도를 사용하여 분석해 본 결과 매우 세심한 디자인 원리가 발견되었다. 휴먼스케일에 입각한 담장의 높이 척도와 경사의 정도에 따라 낮은 경사 쪽에 가중치를 주어 비대칭균형을 조성하는 비례의 원리가 분석되었다. 또한 담장의 리듬을 발생시키는 수평선과 면적의 리듬에서 미적인 수열이 도출되었고, 피보나치 수열과 황금비가 도출되었다. 이는 매우 체계적이고 정량적인 방법으로서 문화재의 미적원리를 분석해 낸 의의와 더불어, 분석된 리듬수열을 모티브로 활용하여 조경리듬설계에 적용한 사례를 제시하였다. 이는 조경리듬설계방법론에 대한 틀과 데이터의 역할을 할 수 있을 것이다.

The tunnel type spillways is under construction to increasing water reservoir capacity in Dae-am dam. Cutting-slope adjacent to outlet of spillways had been originally designed to be 63 degrees and about 65m in height. Examination is carried out in preceding construction that it is caused to some problems possibility which of machine for slope cutting couldn't approach to the site, blasting for cutting slope might have negative influence on highway and roads nearby, and fine view along the Tae-hwa river would be eliminated. In order to establish stability of tunnel and more friendly natural environment that we are carry out detailed geological surface survey and analysis of slope stability. So, we are design and construct for tunnel excavation with possible method that it is keep up natural slope. The result of survey and analysis that natural slope was divided 3 zone(A, B, C zone). In A and B zone, in first removed floating rock, high tensile tension net is install that it prevent of release and falling of rock, in order to security during under working. In addition to, pre-stressed rock anchor is install purpose of security during tunnel excavation because of fault zone near vertical developed above excavation level. Zone C is relatively good condition of ground, design is only carry out random rock bolt. All zone are designed and constructed drainage hole for groundwater and surface water is easily drain. Desinged slpoe is harmony with near natural environment. Successfully, construction is completed.
