The purpose of this study is to draw out objective bases for selecting various applicable facilities in case of the establishment of rainwater management strategies. To do so, sixteen facilities were selected from decentralized rainwater management systems that induce rainwater infiltration and detention as well as centralized end-of-pipe type infiltration and detention facilities in local areas. With these facilities, it attempted to evaluate them in terms of sustainability, pollutant elimination, flood control capacity and costs and subsequently analyzed correlations between each characteristic. The outcomes of the analysis were as follows: First was the analysis of characteristics between decentralized rainwater management systems and end-of-pipe rainwater management systems. From the decentralized rainwater management systems, the mulden-rigolen system and grass swale at street level had the highest in the total of the four items while the totals of the underground detention tank and temporary detention site were highest in end-of-pipe rainwater management systems. After analyzing the correlation between different types of facilities and each variable, it can be said that decentralized rainwater management systems have a higher correlation than end-of-pipe rainwater management systems in terms of sustainability whereas the latter are better in flood control capacity than the former. Second, the analysis of correlation in variables of each facility is as follows: first, there is a negative correlation between sustainability value and flood control capacity value; and there is a positive correlation between flood control capability and pollutants elimination. In addition, it revealed that the higher the flood control and pollutant elimination capability the higher the facility costs. Based on these assessments, it is possible to use them as objective selection criteria for facility application in case of site development project or complex plan.

The objective of this study is to suggest a planning direction for the management and conservation of a rural landscape. For suggesting the planning direction, this study was classified rural landscape resources based on spatial type to understand the assessment of rural landscape. This study examined literature reviews and site investigations for collecting the data on the resources of a rural landscape to maintain rurality. First above all, it was classified into physical and non-physical resources. Non-Physical resources include elements such as inhabitants' will, leaders' will and the software. It is also to reflect all these factors on the planning. Next, this study classified the resources of a landscape into artificial and natural resources and applied these resources to rural areas which were divided into five types: industry area, life area, natural landscape area, program area and human behavior area. The pictures obtained from this field survey were used for a questionnaire survey to understand the value of a rural landscape. The contents of questionnaire survey were divided into two parts: the presentation condition of a rural land-scape and assessment of a rural landscape. Especially, the value of a rural landscape was divided into the ecological value, socio-cultural value and holistic value.

Risk assessment during pre-construction phase is important due to the uncertainty of the risks that may exist in projects. Risk checklist is a method to systematically classify and organize the risks that have been experienced in the past, and to identify the risk factors that may be present in the future projects. In addition, risk value assessment based on checklists plays a key role in risk management, and various risk assessment researches have been conducted to carry out this systematically. However, previous approaches have limitations in common, this is because risk values are evaluated individually in risk checklists, which ignore interdependencies among risk factors and neglect the emergence of co-occurrence of risks. Hence, when multiple risk factors cooccur, they cannot be far off from the conventional method of summing the total risk value to establish the risk response strategy. Most of risk factors are interdependent and may have multiple effects if occurred than expected. In particular, specific cause can be overlapped if multiple risks co-occur, and this may result in overestimation of the risk response for the future project. Thus, the objective of this research is to propose a model to help decision makers to quantify the risk value reflecting the interdependency during the identification phase using existing risk checklist that is currently being practiced in actual construction projects. The proposed model will provide the guideline to support the prediction and identification of the interdependency of risks in practice. In addition, the better understanding and prediction of the exceeding risk response by co-occurring risks during the risk identification phase for decision makers.

댐이 건설된 이후 댐직하류 하천구간은 하천구역내 사유지 경작과 하상주차장 등의 입지, 사주가 발달하여 하폭감소에 의한 문제가 발생하였다. 특히 하천정비의 미흡으로 홍수시 하천통수능력이 감소하여 유역전반에 영향을 미치고 있다. 댐 운영조건도 일부 제약을 받고 있는데 이의 해소를 통한 댐 기능의 회복과 운영의 효율성 제고가 하천의 치수 안정성 확보와 함께 개선대책이 필요하였다. 따라서 댐 운영관리개선과 연계된 댐직하류 하천정비사업이 시행되고 있는데 사업의 타당성, 경제적 편익, 비용배분 및 투자비 회수방안 등과 같은 문제점이 제기되었다. 아울러 댐사업자가 하천사업을 주관한 사례가 없어 이들 사업에 대한 경제성 평가의 객관적 해석과 편익에 대한 정량화 방법의 개발이 요구되었다. 본 연구는 댐직하류 하천정비사업의 사업주체(국가와 용수 및 발전사업자 등)간의 합리적인 건설비용 배분방법을 제시하고 그 적정성을 평가하고자 하였다. 평가결과, 시범 적용 3개 댐의 경제적 편익은 14,405.8백만원/년으로 추정되었고, 편익 중 사업시행자인 K-water의 재무적 가치는 40%, 정부의 공공성 편익은 60%로 분석되었다.

The production of grain for export and domestic use is one of Australia's most important agricultural industries, and the NIR technique has been used extensively over many years for the routine monitoring of grain quality, particularly moisture and protein content. Because most Australian grain is intended for human food production, the determinants of grain quality for livestock feed, apart from protein, have been largely ignored. However the increasing use of grain for feeding to pigs, poultry, beef cattle and dairy cows has led to an important national research project entitled “Premium Grains for Livestock”. Two of the objectives of this project are to determine the compositional and functional characteristics of grains which influence their nutritional quality for the various classes of livestock, and to adopt rapid and objective analytical tests for these quality criteria. NIR has been used in this project firstly to identify a set of grain samples from a large population of breeders' lines which showed a wide spectral variation, and hence a potentially wide variation in nutritional value. The selected samples were not only subjected to an extensive array of chemical, physical and in vitro analyses, but also were grown out to produce sufficient quantities of grain to feed to animals in vivo studies. Additional grains were also strategically selected from farms in order to include the effect of weather damage, such as rain, drought and frost. In this study to date, NIR calibrations have been derived or attempted, on both ground and whole grains, for in vivo dry matter digestibility (DMD), pepsin-cellulase dry matter disappearance, protein, fat, acid detergent fibre, neutral detergent fibre, starch, in sacco DMD and in vitro assays to simulate starch digestion in the lumen and small intestine. Results so far indicate high calibration accuracy for chemical components (SECV 0.3 to 2.6%) and very promising statistics for in vivo DMD (SECV 1.8, $R^2$ 0.93, SD 7.0, range 61.9 to 92.3, n=60). There appears to be some potential for NIR to estimate some in vitro properties, depending upon the accuracy of reference methods and appropriate sample populations. Current work is in progress to extend the range of grains with in vivo DMD values (a very laborious and expensive process) and to increase the robustness of the various NIR calibrations, with the aim of implementing uniform testing procedures for nutritional value of grains throughout Australia.

Amenity landscapes in rural areas are becoming increasingly important as a resource to enhance the (public) interest in rural landscapes and to vitalize the rural areas. Befitting the times, the objective of this project is to discover the amenity landscapes distributed throughout the rural areas and to produce material in the form of a publication for the promotion of the aforementioned landscapes. For such purposes, local autonomous bodies, rural amenity resource investigation team, and experts on landscape found rural amenity landscapes and entered them for a selection process, out of which the top 100 rural amenity landscapes were ultimately selected based both on the assessment system developed by the researchers and on the assessment process executed by the assessment committee. The following two categories of assessment criteria for the amenity landscapes were presented: village-related assessment criteria including value as resource and use value; landscape-resources-related assessment criteria, including aesthetic value, identity, adherence to traditionality, and sustainability. Assessment for each criteria item was made by applying a 5-point Likert scale throughout. The sum of the points for each landscape was then converted at a 100 point scale for ultimate use in selection of the top 100 landscapes. This paper is the outcome of such series of processes and systems.
