This study was conducted for the purpose of presenting basic data for calculating a more reasonable landscaping project cost in the future through the construction cost calculation ratio of scenic planting and facilities and their time series trend analysis targeting 'J' corporation, a representative Korean public institution that creates apartment complexes. This study targeted scenic planting and the facility construction costs of 37 apartment complexes in the capital area from 2004 to 2012, using statistical analysis methods such as technical analysis, correlation analysis, and regression analysis to analyze the characteristics of the time series change. The conclusion was drawn as follows. First, breaking down the cost of overall landscaping projects to scenic planting and facility construction, the ratio of the average cost of scenic planting to that of facility construction showed 56.1% to 43.9% from 2004 to 2012. Second, the costs of planting construction and facility construction both showed a fluctuation range of about ${\pm}3%$, implying relatively steady costs considering the inflation rate. Third, the landscape construction cost for each type of construction resulted in a fluctuation range from minimum ${\pm}3%$(exercise facility) to maximum ${\pm}5%$(packing facility), reflecting that among the landscaping projects, the facility construction costs tended to show relatively large fluctuations in accordance with the change of time series. Fourth, the comprehensive indication of the ratio of landscaping project costs by time series and landscaping construction type implies that the regional characteristics and positional condition of the apartment complexes were not reflected sufficiently. Fifth, the high level of correlation of landscaping construction types and landscaping construction elements imply that the entire construction costs were controlled through partial adjustment of cost components within the overall frame of construction cost. These results reveal the problems of standardized landscaping cost irrespective of user satisfaction or environmental traits such as the conditions of the apartment complexes.

산업자원부에서는 국가에너지사업의 정책으로 지역 에너지사업 및 신 재생에너지 시범보급사업을 수행하고 있으며, 이에 따라 대규모 신재생에너지전원(태양광, 풍력, 열병합 등) 단지가 활발하게 조성되고 있는 상황이다. 그러나 신재생에너지전원의 설치자 측에서는 설비비용의 절감을 이유로 일반배전선로(고압 및 저압배전선로)에 직접적인 연계를 요구하고 있으나, 한전 측에서는 계통운용의 어려움으로 인하여 까다로운 계통연계지침(가이드라인)을 정하여, 한전 측과 전기사업자(전기공사업자 및 발전 사업업자)간의 이해가 상충되는 부분이 발생하고 있는 실정이다. 따라서 본 연구에서는 신재생에너지전원의 발전업자와 전기공사업자의 측면에서는 효율적인 공사 및 시공을 위하여, 배전계통 연계와 관련된 복잡한 기술적인 계통연계 지침을 일일이 해석하지 않더라도, 연계 적합여부를 손쉽고 자동적으로 판단해주는 평가시스템을 개발하였다.

The layout of haul routes within a construction site of large complex projects needs to be carefully determined as the productivity of earthwork activity heavily depends on the efficiency of the layout and the routes are not likely to change once they are settled. This paper aims to provide a construction planner with a reliable framework to create an efficient layout of haul routes within a large complex construction site. To construct the framework, five factors affecting haul route layout and the productivity of earthwork activity are described along with the associated rules of thumb recommended by design and field experts. In addition, a methodology based on spatial analysis using raster format in GIS is proposed to further increase haul route efficiency. The proposed planning framework enables a construction planner to easily find a more reliable route layout by thoroughly considering the key factors prior to setting up an earthmoving plan.

As a study for offshore wind farm, we investigated the fish fauna of the Wi-do, Younggwang-gun, Chollabuk-do, Korea. From the four times collection of fish species from October 2013 to June 2014, we collected 46 species of 26 families including 9 orders. Among them, the fish of family Gobiidae includes the most number of six species (13.6%). The dominant species was the Argyrosomus argentatus with 53.10%. Total of 17 fish species, including the Cynoglossus joyneri were collected from all of four collecting sites. On the other hand, 13 species including Inimicus japonicus were collected from only one site. Being the wind farm under construction, fish will temporary decrease in this area. But in the long term, we think that Oplegnathus fasciatus, Sebastes shlegelli and others will increase with good inhabited environment provided by the wind farm structures.

The indices to choose the object countries for developing overseas industrial park were developed and applied in this paper. The results are showing as follows. First, the Korean enterprises are branched out into total 128 countries as of the first quarter of 2010, and the 13 asian countries including China, Vietnam, Japan, and Hongkong shows the majority of precedence 20 countries among the reported during 1980-2010. Second, the 3 steps of selecting the principal region to branch out, establishing assessment indices and criteria, and choosing strategical target counties were developed to choose the countries for developing overseas industrial park. The 38 of 128 countries were selected where the GDP per capita is lower than Korea, and the local reports of incorporation during 2007-2010 are more than 10 times. Then, the 10 countries were excluded where the minimum wages during 2008-2009 are similar to Korean ($815/month). Consequently, the 28 countries including China, Vietnam, and Cambodia etc. were selected as the major target regions. Third, the indices to choose countries for developing overseas industrial park are classified into 5 categories-investment condition, labor market flexibility, potential market demand, population, changing rate of the reported number of manufacturing industry, and detailed indices for each category were selected, then the weight were given with the consideration of importance. Finally, Indonesia, Mongolia, and Uzbekistan were selected as the strategical target counties where acquire the high score in labor market flexibility and investment condition, relatively undeveloped, and friendly to Korea.

Based on field observed tide, tidal currents and depth data, hydrodynamic changes on the Keum River Estuary has been analyzed in which huge complex constructions has been made simultaneously. According to the analyses from acquired data over 2 years, rapid increasing of tidal currents and resulting scouring of 50 cm/yr has been reported in flow-guided dikes region of Kunsan Outer Port. However inner part of the Saemankeum sea dike and Kunjang Industrial Complex dike, 30 cm of sedimentation were found during 2 months of fall season in tidal flats and hence very rapid transition of hydrodynamic system on this area are resulted from those constructions which are still on going nearby.

Various geotechnical problems due to insufficient bearing capacity or excessive settlement are likely to occur when constructing roads or large complexes on soft ground. Accurate predictions of the magnitude of settlement and the consolidation time provide numerous options of ground improvement methods and, thus, enable to save time and expense of the whole project. Asaoka's method is probably the most frequently used one for settlement prediction and the empirical formulae such as Hyperbolic method and Hoshino's method are also often used. To find an elaborate method of predicting the embankment settlement, two recurrent type neural network models, such as Jordan model and Elman-Jordan model, are adopted. The data sets of settlement measured at several domestic sites are analyzed to obtain the most suitable model structures. It was shown from the comparison between predicted and measured settlements that Jordan model provides better predictions than Elman-Jordan model does and that the predictions using CPT results are more accurate than those using SPT results. It is believed that RNN using cone penetration test results can be a highly efficient tool in predicting settlements if enough field data can be obtained.
