Recently, as the paradigm of regional development has been transformed into characterization, decentralization and cooperation, small and medium scale development is in the spotlight. In particular, as the transfer of planning authority to local governments accelerates, LH is in the process of seeking to transform itself into a system that is in line with local government demand. The purpose of this study is to elaborate the regional pending projects that meet the demand of the region. The Jeju Special Self-Governing Province is the area where land and housing prices have increased more than three times recently, which is the area of interest in recent years due to the various demand for development projects. Another objective is to establish a local government based on LH's system, it is aimed to derive a collaboration method with local government, province corporation and local researchers. The criteria for deriving the cooperation projects between the local government and LH are basically the ones that can be carried out by LH and future-oriented projects. The process of deriving has undergone the process of statutory planning, unscrupulous plan analysis, and consultation of experts' advisory committees. In order to derive the regional cooperation project, four criteria such as local uniqueness, future possibility, business promotion efficiency, and local cooperation project were set. Major projects of the Jeju Special Self-Governing Province are improvement of the surrounding traffic system, construction of the hinterland due to the construction of the second airport, and establishment of Cruise Port(Jeju Port, Seogwipo Port). The role of each entity in the implementation of regional cooperation projects is as follows. Local government should request subsidies for the projects in case of lack of budget support and secure them through competition with other regions. In addition, it should be responsible for the operation and management of the facility once it has been supported and completed smoothly. The Ministry of Land, Infrastructure and Transport affects each region through approval and subsidy of the development plan. After the development project is completed, it evaluates the development project through monitoring and plays a role of continuously improving the system. As a business operator, the provincial corporation will carry out small-scale projects including non-physical projects such as community participation. In the case of LH regional headquarters, the general manager of the region will establish a comprehensive business plan, secure development availability, and carry out large-scale growth promotion projects.

관광지역 내 궤도교통수단 요금은 사업 타당성 판단의 중요한 변수가 되는 요소이다. 기존 운영자 위주의 요금 결정에서 벗어나, 이용자 측면까지 동시에 고려된 요금을 산출함으로써 운영자와 이용자를 동시에 만족시키는데 본 연구의 목적이 있다. 본 연구의 대상은 인천광역시 중구 월미도 일대를 순환하는 월미은하레일이다. 본 연구에서는 요금의 적정 범위를 판단하기 위해 운영자 비용과 이용자 비용을 최적화하는 모형을 구축하였다. 최적화된 모형을 활용하여 각 변수의 값을 산출한 결과, 정류장 간격은 0.532km, 운행 간격은 0.206시, 정류장 수는 12개소, 운행 대수는 3대로 도출되었다. 이렇게 도출된 변수들을 활용하여 이용자가 지불해야하는 최소요금과 운영자가 징수해야 하는 최소요금을 산출하고, 이를 근거로 요금의 적정범위를 분석한 결과 최소 1,261원에서 최대 5,063원인 것으로 분석되었다. 관광교통수단의 경우 정류장 자체가 관광지 내에 위치하므로 모형 적용시 접근거리 감소폭이 매우 적어 접근비용의 변화폭이 미미하다는 점을 확인할 수 있었다.

The Korean environmental impact assessment(EIA) system, and explored ways to improve it as a more efficient and viable institution relevant to the demand of our time and conditions in study. The first problem this study identified is found in the fact that the party to write up the assessment report is itself the business operator or the one who is planning to work out the business plan. This structure translates into placing an order with an agent for EIA report. The reporting job may br subcontracted to the agent at a cost far below the rate specified in the 'Standard for Estimate of Agency Fee for Environmental Impact Assessment.' This practice also causes the vicious circle of producing a report that is written to justify the project or business in question or it leads to rough-and ready and poor documentation to minimize the time required. Second, in order to achieve the goal of the plan or business, which is the target of EIA, the local residents tend to ve regarded as an obstacle. This means elimination of the local people from participating in the EIA or their opinion being frequently ignored. This is the seed of distrust and hostility that sometimes provoke disagreements or fierce conflicts. The first proposal to improve these problem is to improve the factors that cause poor documentation of the assessment report as well as improve the understanding of the EIA system. This study proposes the following measures for improvement. The agency cost for EIA should be paid by the business operator or a third party that can ensure faithful implementation of the payment. A system should be established to verify transparent estimation of the agency cost. In order to enhance the professional quality of EIA agents, there should be implementation of qualification test for industrial engineer of related engineers in addition to the current EIA Qualification Test. The second proposal for improvement is to improve the citizen participation process by instituting a legal framework to make clear the purpose of the briefing session for local residents, which is held as a procedure of EIA, and to ensure more positive publicity during the stage of listening to the opinion of the local community. For a smooth and rational communication process, a moderator and a communicator of opinion, as is the case in a public hearing, could be instituted to clearly get the purpose of the briefing session across to the residents and to help to carry out the explanation and Q & A sessions according to the categories of the opinion of the residents. At present, the notification of the public inspection of the draft of the assessment report and briefing session for the residents is made on the newspaper and internet network. But some people have difficulty with access to this method of announcement. A higher participation rate could be secured if a legal provision is added to specify putting up placards in specific places such as the entrance to the place for the briefing session for residents or the building of administrative agencies of the area concerned.

In order to monitor greenhouse gases including $CO_2$, various types of surface-, aircraft-, and satellite-based measurement projects have been conducted. These data help understand the variations of greenhouse gases and are used in atmospheric inverse modeling systems to simulate surface fluxes for greenhouse gases. CarbonTracker is a system for estimating surface $CO_2$ flux, using an atmospheric inverse modeling method, based on only surface observation data. Because of the insufficient surface observation data available for accurate estimation of the surface $CO_2$ flux, additional observations would be required. In this study, a system that assimilates aircraft $CO_2$ measurement data in CarbonTracker (CT2013B) is developed, and the estimated results from this data assimilation system are evaluated. The aircraft $CO_2$ measurement data used are obtained from the Comprehensive Observation Network for Trace gases by the Airliner (CONTRAIL) project. The developed system includes the preprocessor of the raw observation data, the observation operator, and the ensemble Kalman filter (EnKF) data assimilation process. After preprocessing the raw data, the modeled value corresponding spatially and temporally to each observation is calculated using the observation operator. These modeled values and observations are then averaged in space and time, and used in the EnKF data assimilation process. The modeled values are much closer to the observations and show smaller biases and root-mean-square errors, after the assimilation of the aircraft $CO_2$ measurement data. This system could also be used to assimilate other aircraft $CO_2$ measurement data in CarbonTracker.

The study of human erroneous actions has traditionally taken place along two different lines of approach. One has been concerned with finding and explaining the causes of erroneous actions, such as studies in the psychology of "error". The other has been concerned with the qualitative and quantitative prediction of possible erroneous actions, exemplified by the field of human reliability analysis (HRA). Another distinction is also that the former approach has been dominated by an academic point of view, hence emphasising theories, models, and experiments, while the latter has been of a more pragmatic nature, hence putting greater emphasis on data and methods. We have been developing a method to make predictions about error modes. The input to the method is a detailed task description of a set of scenarios for an experiment. This description is then analysed to characterise thd nature of the individual task steps, as well as the conditions under which they must be carried out. The task steps are expressed in terms of a predefined set of cognitive activity types. Following that each task step is examined in terms of a systematic classification of possible error modes and the likely error modes are identified. This effectively constitutes a qualitative analysis of the possibilities for erroneous action in a given task. In order to evaluate the accuracy of the predictions, the data from a large scale experiment were analysed. The experiment used the full-scale nuclear power plant simulator in the Halden Man-Machine Systems Laboratory (HAMMLAB) and used six crews of systematic performance observations by experts using a pre-defined task description, as well as audio and video recordings. The purpose of the analysis was to determine how well the predictions matiched the actually observed performance failures. The results indicated a very acceptable rate of accuracy. The emphasis in this experiment has been to develop a practical method for qualitative performance prediction, i.e., a method that did not require too many resources or specialised human factors knowledge. If such methods are to become practical tools, it is important that they are valid, reliable, and robust.

The projects are becoming more complicated and amplified as the design and development technology is advancing. Thus, existing architectural processes and methods are revealing limitations. The technology of BIM is an IT applied to construction, that provides the state-of-the-art tools to overcome these limitations to improve on architectural designing, technology, cost, etc. Therefore, it it necessary to converge the advises and collaboration from the various experts at the initial step in a common processing platform. In this research project with Korean Education Development Institute, configuration and utilization of EDU BIM template is studied because setting an anchor point from the initial phase is necessary for such processes at the perspective of the operator. The purpose of this study is to prevent time consumptions at the initial phase of BIM foundation, to ensure accurate information inputs within the repetitive tasks, and for effective information management that will produce consistent results through utilization of BIM technology.
