With recent attempts to improve quality and productivity, the prefabrication manufacturing system has been occupying an increasing share of the construction area. To minimize site work, material is more frequently being produced and partially assembled at a plant, and then installed at a site. For this reason, the production process is being divided and the materials are being delivered to the site after passing through multiple plants. With these changes in the production process, the materials delivery plan is becoming an important management point. In particular, as road transportation using trucks has a 71 percent share of the domestic transportation market, selecting the proper transportation path is important when delivering materials and equipment to a site. But the management system at the project design phase to calculate the delivery cost by considering the production process of the pre-fab material and the $CO_2$ emission at the material delivery phase is currently lacking. This study suggests a process design model for assembly production of the pre-fab material and transportation logistics based on carbon emission. The suggested model can be helpful to optimize the location of the intermediate plant. It is expected to be utilized as a basic model at the project plan and design phase when subcontractors make decisions on items such as materials procurement, selecting the production method, and choosing the location of the assembly plant.

This paper discusses of the problem of direction and orientation of site design of a traditional Korean village. The research focus on how the directional orientation of each houses adapt the direction of the flow of surrounding mountains. The direction of mountains worked as a prime rule which most of the houses( 76.6%) observed the same direction as their own orientation. While the central part of the village followed the direction of mountains more strictly, however the houses on the periphery area tend to be more free from the direction of mountains. This houses of the periphery respect either the direction of the mountain flow right behind the house or faces toward the south.

실제 국내에서 관측된 가속도를 이용한 스펙트럼 값이 내진설계기준보다 상대적으로 크게 나타나는 경향을 보이며, 특히 고진동수 구간에서 국내 내진설계 기준이 국내 고유의 지반증폭 특성을 제대로 반영하지 못하고 있어 문제점이 많다고 지적되어 왔다. 지반증폭 특성을 분석할 때 여러 가지 방법이 제시되어 왔으며 본 연구는 현장에서 자주 적용되고 있는 지반진동의 수평/수직 스펙트럼 비율을 이용하는 방법을 적용하였다. 이 방법은 S파 및 레일리파를 이용하는 것으로부터 출발하였으나, 최근 Coda파 및 배경잡음 등에 확대 적용되어 지반의 동적인 증폭특성 연구에 많이 이용되고 있다. 제한된 연구 기간 동안 4개 변전소시설 관측소 각각 2개 지점(노두 및 시추공)에서 운영되었고 본 연구는 4개 관측소의 노두에서 동시에 관측된 3개 중규모 지진의 가속도 지반진동(S파, Coda파 및 배경잡음)을 이용하여 지반증폭을 분석하였다. 분석결과는 4개 관측소 각각에 대해 기존 연구결과인 시추공 지반증폭 특성과 상호 비교하였다. 또한 각각 관측소 및 지점에서 지반의 우월진동수를 이용하여 각각 지반에 대한 등급분류도 시도하였다. 각각의 지진관측소마다 저진동수 및 고진동수 특성, 관측소 고유의 우월진동수가 서로 상이하여 관측소 고유의 증폭특성을 보여주었다. 대다수 관측소는 S파, Coda파 및 배경잡음 에너지를 분석한 결과와 많은 부분이 유사함을 보여 주었다. 물론 본 연구로부터 도출된 결과를 다른 방법에 적용하여 얻어진 결과와 비교한다면 지반의 동적 특성 및 지반분류 연구에 많은 정보를 제시할 수 있다고 판단된다.

The location of villages differs by position, and the method to form the conditions of location varies greatly. This study has comprehensively investigated village layout in the riverside and directional relations in houses. With changes in riverside landscape and transition to an agriculture-oriented village, there have been changes in road and the size, shape and direction of houses as well. In terms of the direction of houses situated along the river, a house facing the river accounts for more than half of all houses in the village. As traditional houses are transformed into modern houses over time, houses have become bigger, and the number of the houses facing south or southeast has been on the rise. As described above, riverside landscape and preference for the house facing south have an effect on determination of the facing direction of houses. However, the direction of geographical features of the village was first followed, and other conditions have been reflected, and the characteristics for the facing direction of houses have been observed.

The Seoul Housing Corporation pronounced a design competition for Eunpyeng New Town District 2 in March of 2005. The authors collaborated on this design and won rot prize. Design guidelines of this competition were to make environmentally sustainable design, to develop as a resort site and cultural place for everyday life of residents, to link with green fabric of the district, and to elevate positive image and identity of Eunpyeng New Town district by creating a attractive landscape. The authors developed design concept and strategy within the guidelines and site conditions. The environmental setting of this site was characterized by mountain to the rear of the site with a stream passing through the district and the front of the site. This is the most important condition for the location principle of residence in Fung Shui theory. Therefore, the schema of the design was introduced by Fung Shui and Chi of place. To evolve design concept, we reinterpret the Fung Shui and Chi in the site combining with modem landscape design strategy, so that good place making could bring about well-being life of residents. By doing that, design concept of the proposal evolved as follows: 'fullness of comfortable life', 'adaptation of nature', 'inspiration of natural force'. This design approach is critical reevaluation of regional characters employing modem strategy. It is a conscious strategy of critical regionalism as distinguished from the traditional site oriented approach. The following are some of the major features in the design: green network and water recycle system in the site, promenade of forest with the experience nature, link to community core, theme gardens with plants having strong fragrances, terrace gardens with different level of housing type, playgrounds and resting places with many types, human scale facilities for residents.

This study aims to find out the best anode location for buried pipelines. Numerical simulation program known as CATPRO (Elsyca, Belgium) were used for confirming the best location of anodes and the effects of impressed current cathodic protection system. Applied conditions for numerical simulation were similar to on-site environmental conditions for optimal application of cathodic protection system. Used criterion of cathodic protection was NACE SP 0169, which describes that minimum requirement for cathodic protection is -850mV vs. CSE. Various layouts for anodes' installation were applied, which were distance between anodes, anode installation location, and applied current. The areas where cathodic protection potential was lower than -850mV vs. CSE was limited up to 50m from anode installation locations. It was founded numerical analysis obtain cost-effective and efficient cathodic protection methods before design and application the impressed cathodic protection system to on-site environment.

A study of the wave conditions for the Asabo offshore location at the Qua Iboe oil field in Eastern Nigeria has been carried out. Statistical analysis was applied to three (3) years of data comprising spectral periods, Tp and significant wave heights, H_s. The data was divided into two (2); data from October to April represents one set of data and data from May to September represents another set of data. The results were compared with similar studies at other locations offshore of West Africa. It was found that there is an absence of direct swellwaves from the Southern Ocean reaching the location under study (the Asabo site). This work suggests that the wave system is largely emanating from the North Atlantic storms. The presence of numerous islands near the Asabo location shields the site from effects of storms from south west and therefore swells from the Southern Ocean. It is noted that the local wind has little or no contribution. An H_s maximum of 2 m is noted at the Asabo offshore location. It is found that the Weibull distribution best describes the wave distribution at Asabo. Thus, the Weibull distribution is suggested to be adequate for long term prediction of extreme waves needed for offshore design and operations at this location.
