PURPOSES : This study is to improve the highway management and rehabilitation efficiently by method for asset management. METHODS : Based on the literature review, The concept of this paper is to investigate the use of asset values from a Bridge management system to improvement of maintenance system more efficiently. This study is suggested for an evaluation method based on the current bridge condition by Written-down replacement cost of the assets. RESULTS : We suggests the optimization methodology of road asset valuation for budge distribution and performance measure. CONCLUSIONS : We evaluate all of national highway's bridge by the optimization methodology of road asset valuation, and suggest application methods of asset result.
Environment standards can be used as a foundation of environment administration (specific expression of political goals or quantitative evaluation standards of political effects). When environment adminstration improves severe air or water pollution rapidly, the environment standard can work effectively to show the goals specifically and clearly. The environment index which is designed to evaluate environment systems, should be established to express the environment system generally. To realize sustainable development, the sustainable indexes usually consisting of these three areas in that harmony of environment, economy and society are required. In this research, sustainable environmental indicators to understand the characteristics and to compare likes theme of environmental conditions in international and national level indicators, regional environmental management plan to promote the management by objectives are to provide the basic data. It is desirable for the environmental policies to work harmoniously with direct control, use of economic means and voluntary methods. Regarding the evaluation of environmental index, the action results of civilian's or individual's activities are needed to be reflected into the evaluation.
본 연구는 PIT tag (passive integrated transponder)과 무선추적법(radio telemetry)을 오대산국립공원과 월악산국립공원에 서식하고 있는 파충류에 적용한 후, 이를 평가하여 효과적으로 국립공원 내 파충류 자원관리 방안을 모색하기 위하여 수행되었다. PIT tag은 현재까지 알려진 파충류 개체표시법 중에서 가장 효과적인 방법으로 2006년 3월부터 2008년 10월까지 오대산국립공원과 월악산국립공원의 조사지역에 출현한
Total water pollution load management(TWPLM) seeks to harmonize conservation and development by allowing regional developments to be carried out in an eco-friendly manner and within the scope of achieving the desirable water quality. Water pollutant sources are managed so as to keep the total amount of pollutants in public watersheds within a certain level or total allowance in accordance with target water quality goal. With relation to the basic guideline under the Special Act on the Water Resources Management and Community Support for Watersheds, the load from the land should be determined by the classification of rainy and dried season respectively. Objective loads of abatement applied in the 1st planning period(2004∼2010) are set up standards by low flow condition(Q275) without considering the change of flow, while allowable wasteloads are estimated by the criteria of daily mean precipitation 10 mm, as critical standard for the division of surface runoff load. Even though the standard flow conditions to meet the goal of water quality at the end of unit watershed are low flow, but it might be considered to set up drought flow condition(Q355) for the improvement of water quality. Also the objective loads for abatement to meet the target water quality should be calculated without the effect of non-point sources from the land.
본 연구는 우리나라에 자생하는 순비기나무의 실생묘와 삽목묘를 이용하여 토양의 종류와 시비방법에 따른 재배방법을 구명하고자 한 것으로서, 그 결과를 요약하면 다음과 같다. 순비기나무의 1년생 실생묘와 삽목묘를 모래, 마사토, 황토 등 3종류의 토양에 시비하지 않고 재배한 결과, 실생묘는 모래와 마사토에서 70% 그리고 황토에서 35%의 생존율을 나타내었고, 삽목묘는 마사토에서 90% 그리고 모래와 황토에서 80%의 생존율을 나타내었다. 실생묘와 삽목묘 모두 전반적인 생장은 마사토와 모래에서 양호하였고, 황토에서 비교적 불량하였다. 실생묘의 경우는 줄기생장이 양호하였고, 삽목묘의 경우는 뿌리생장이 양호하였다. 마사토를 기본토양으로 하고 비료의 종류와 시비량을 조절하여 재배하였을 경우에 유기질 비료만을 기비로 시비한 시험구에서만 묘목이 생존하였고, 무기질비료와 액비를 시비한 시험구에서는 식재한 묘목이 모두 고사하였다. 시비구에서 삽목묘는 실생묘에 비해 월등히 높은 생존율을 나타내었고, 특히 소량 시비구에서는 실생묘에 비해 2배 이상 높은 생존율을 나타내었다. 이상의 결과를 요약하면, 순비기나무 묘목을 재배할 때에 삽목묘가 실생묘보다 전체적인 활착과 생장이 양호하며, 토양에 대한 적응성도 높고, 토양비옥도에 대한 요구도가 적은 것을 알 수 있었다.
As competition in manufacturing enterprise is contested, the scope of safely production planning, manufacturing enterprise should ensure, has been reduced. The more upstream of SCM, the more reduction of scope of production planning. As a result, order fluctuation is more sharply contested. Through improving the logistics network, it is best way that the end user's demand information is conveyed to upstream of SCM, but it is difficult in fact. In this paper, it mention the way of robustic adjustment, in the suppliers' point of view, the end user's demand information is dammed up, as they postpone responding the customer's order as a possible. And it will show the result of appling the way, as a case study.
Safety check-up and individual education, safety status wishes to present included safety assessment table for safety management assessment system construction about unit work process in Study. Safety management assessment table gives each grades about worker of unit work process, safety check-up, education, management and identifies merits and demerits of unit work process, it is that propose safety management assessment system that can reduce accident occurrence possibility.
Recently, youth unemployment is not a mere economic problem in Korea. It could be developed into a serious social problem. It has been long since youth unemployment rate was more than double in total unemployment rate, which stood at 3.5 percent in 2005
Today the usage of DB already becomes an important issue for many companies' survival. Especially, the companies which have adopted CRM could not gain the return to be expected because of the lack of understanding about the relationship with customers. Professor Schmitt introduced 'the complete CEM(Customer Experience Management) model', but no specific methodology for analysis was introduced. Therefore, in this study we use HOQ, GA, and ANP to build 'the complete CEM model' and present the integrated CEM model based on the integrated analytic process to help the company's decision about the stage to be begun first out of 5 stages of CEM and the priorities of investment in customer experiences.
In order for the analysis of effect in the respective preventive measures which is being carried out by a small & medium sized company against any potential accident, this research relates to the followings: We investigated the situation of an accident occurred in the company in which his obligation of selecting a safety manager is exempted, in accordance with the industrial safety & healthcare & enforcement ordinance, enforcement rule. We investigated the situation of an accident occurred in the company which entrusted the specialized organization with his own safety control notwithstanding it is free from an obligation to have any safety manager for aiming at the comparison and analysis of the outcome. The economic and preventive effect of industrial accident has been compared and analyzed in order to strengthen the obligation of selecting a safety manager.
Statistical process cintrol is intended to assist operators of a stable system in monitoring whether a change has occurred in the process, and it uses several control charts as main tools. In design and use of control chart, it is rational that probabilit
In this study, we establish bootstrap control limits for robust M-estimator chart by applying the bootstrap method, called resampling, which could not demand assumptions about pre-distribution when the process is skewed and/or the normality assumption is doubt. The results obtained in this study are summarized as follows : bootstrap M-estimator control chart is developed for applying bootstrap method to M-estimator chart, which is more robust to keep Type Ⅰ error when process contain contaminate quality characteristic.
