The purpose of this study is to analyze the actual situation of residents' participation in rural development projects, to identify their performance and problems, and suggest ways to develop desirable villages in rural areas. From reviewing relevant pre-studies, this study was done by interview, questionnaire, and observation targeting 140 leaders and residents of exampled village of the project in Jeollanam-do, as well as by listening opinions of relative experts. This study is largely classified into 4 parts, review of character and appearing background of village development project, review of theoretical discussion about residents' participation, evaluation of accomplishments and analysis of participation, and establishing a model for habitants-participating village development project and how to improve it. As a result of questionnaire, it was found urgent for habitants to convert their thinking about village development and their participation in it, to realize a model of this project, as well as political stimulus to promote that. Therefore, measures must be required to improve current village development projects and to promote them. First of all, a preparation period is required to sufficiently provide the village where habitants are willing to participate in, from the state of place selection. Besides, it is required to run away from profit-making businesses aiming at foreign people, to improvement of residents' welfare in a long term, and enhanced resources management in a broad view. Waste of working expenses seems to be solved through direct operation by a corporation in charge of profit-making businesses, under superstition of residents' community. Finally conclusion, expansion and practicalization of education to residents are essential, to promote their participation in rural development projects. Especially it must be practical education for habitants such as 'community-ship' or 'technology education in each interesting part,' rather than tour of other villages and unilateral lectures from experts. Along with this, a long term plan and systematic participation is more essential. Since planning itself can be mutual learning to enhance residents' capacity, a chance must be established to discuss and plan each part including resources-research, by making them participate in.

This study aimed at the identity of the landscape architectural award, which is the highest authority award system in landscape architecture; the establishment of cooperation between the landscape architecture and urban public sector, which deals with infrastructure is significantly requested nowadays. The identity characteristic of a detailed concept which configures the sameness in the shape of inner self-cognition and individuality as external and correlative cognition are utilized as the research methodology, and the findings are summarized as follows. The Korean Landscape Architectural Award holds an internal value as the only award in landscape architecture that is granted municipalities and public agencies. However, when it is compared with several correlated award systems, the vulnerable sides such as short origin and partly limping in terms of sustainability, the possibilities of losing the interest in the public sector due to management's reform program and insufficient participants and responses regarding social authority have been found. In addition, according to the today's paradigm tha taims for green cities, the aspect that shares the large portion with the values set by detailed categories of city planning that enforces metropolis awards is also in the spotlight. Hence, the landscape architectural award should construct specialization and development strategies by strengthening the superiority compared with the city award in the field of city planning. In other words, the Ministry of Land, not limited to the systematic cooperation with various administrative areas will be strengthened and it will communicate with the aspect that reinforces characters as an academic and practical area that covers various districts and disciplines. Thus, the identity is directly connected to the landscape architectural award's competitive reinforcement as a detailed characteristic variously combined, and it requires huge interest and discussions regarding internal and external landscape architecture areas and the democratic public discussion process.

Computational chemistry is one of the chemistry fields that deals with the theoretical chemistry problem using computer calculations and can be described as the chemistry lab moved on computer space. In line with recent enhancement of processing capability of computers, utilization of high performance computer cannot be overemphasized in the field of computational chemistry in performing complex calculation of huge molecular structure and simulation. While they have to use commands and consoles for high performance computer to execute complex calculation of huge molecular structure and simulation, most of students in natural science and engineering, who are not experts in computer technically, are likely to be unaware of UNIX. Under the circumstances, web-based educational support system for computational chemistry is needed to enable them to practice computational chemistry, even not knowing UNIX command. In this study, e-Chem, one of such educational support systems, is developed by using Liferay portal platform, which is a Java open source more oriented to standard and outstanding in its content management and collaboration function than other web portals. By using this system, even students who are not familiar with computer, are expected to take part in lab classes and save time learning Unix command and also enhance the learning efficiency by using familiar interface.

According to the statistics of the Ministry of Environment, the emission of sewage sludge is increased by 7~9% yearly. In the future, it will be increased continuously because of extension of sewage disposal plants, high class treatment for removing nitrogen and phosphorus. Until now, we have depended on reclamation for lots of quantity and some part has been treated by ocean emission. But, direct reclamation of organic waste will be prohibited and even ocean emission will be prohibited now, so the treatment of sludge is put on emergency alert. Bio-gas can be produced by applying anaerobic digestion method for the recycling or refuse derived fuel can be conducted by applying carbonization method. However, the process is difficult, causes bad smell and makes it the second waste, so it cannot be practical method in fact. This study applied a fluidized bed combustor for sewage sludge treatment technologies that can actually take advantage of key technologies in order to verify its purpose is to demonstrate selected. If applying the fluidized bed combustor, it can be easily utilized as the replaced resource of energy(fuel) in the countries whose energy resources are insufficient, like our country. Especially, if applying only original strengths of the fluidized bed combustor sufficiently, the sewage sludge can be treated simply, eco-friendly, sanitarily and economically. Particularly, it is verified as the energy technology suitable for government's green growth policy.

Reliable assessment of Land Use and Land Cover (LULC) changes greatly improves many practical issues in hydrography, socio-geographical research such as the observation of erosion and accretion, coastal monitoring, ecological effects evaluation. Remote sensing imageries can offer the outstanding capability to monitor nature and extent of land and associated changes over time. Nowadays accurate analysis using remote sensing imageries with high spatio-temporal resolution is required for environmental monitoring. This study develops a methodology of mapping and change detection in LULC by using classified Korea Multi-Purpose Satellite-2 (KOMPSAT-2) multispectral imageries at Jeonbuk and Jeonnam provinces including protected tidal flats located in the west coasts of Korean peninsula from 2008 to 2015. The LULC maps generated from unsupervised classification were analyzed and evaluated by post-classification change detection methods. The LULC assessment in Jeonbuk and Jeonnam areas had not showed significant changes over time although developed area was gradually increased only by 1.97% and 4.34% at both areas respectively. Overall, the results of this study quantify the land cover change patterns through pixel based analysis which demonstrate the potential of multispectral KOMPSAT-2 images to provide effective and economical LULC maps in the coastal zone over time. This LULC information would be of great interest to the environmental and policy mangers for the better coastal management and political decisions.

High resolution intertidal DEM is a basic material for science research like sedimentation/erosion by ocean current, and is invaluable in a monitoring of environmental changes and practical management of coastal wetland. Since the intertidal zone changes rapidly by the inflow of fluvial debris and tide condition, remote sensing is an effective tool for observing large areas in short time. Although radar interferometry is one of the well-known techniques for generating high resolution DEM, conventional repeat-pass interferometry has difficulty on acquiring enough coherence over tidal flat due to the limited exposure time and the rapid changes in surface condition. In order to overcome these constraints, we tested the feasibility of radar interferometry using Cosmo-SkyMed tandem-like one-day data and ERS-ENVISAT cross tandem data with very short revisit period compared to the conventional repeat pass data. Small temporal baseline combined with long perpendicular baseline allowed high coherence over most of the exposed tidal flat surface in both observations. However the interferometric phases acquired from Cosmo-SkyMed data suffer from atmospheric delay and changes in soil moisture contents. The ERS-ENVISAT pair, on the other hand, provides nice phase which agree well with the real topography, because the atmospheric effect in 30-minute gap is almost same to both images so that they are cancelled out in the interferometric process. Thus, the cross interferometry with very small temporal baseline and large perpendicular baseline is one of the most reliable solutions for the intertidal DEM construction which requires very accurate mapping of the elevation.

Studies were conducted on the nature of allelopathic effect of the substances in the waste of ginkgo leaves from pharmaceutic factory. In the first step, to find out whether there was any allelophatic effect, young seedlings of radish and rice were grown in the water (crude) extract of ginkgo leaf waste and in different liquid/lquid partitioned fractions of EtOAc at pH 9, EtOAc at pH 3, and BuOH. As second step, attempts were made to isolate and identify the allelophatic substance in different liquid/liquid partitioned fractions using GC/MS and NMR techniques. The water (crude) extract of ginkgo leaf waste retarded the growth of radish seedlings under 10% concentration. In case of rice seedlings, the water extract of ginkgo leaf extract showed adverse effect on the growth when combined with $3.3{\times}10^{-6}M$ gibberellin A3. All of the liquid/liquid fractions of crude extract showed strong retardation of seedling growth of radish and rice at the concentration of 1%. Allelophatic substance was isolated from the crude extract using liquid/liquid partition, column chromatography and HPLC techniques. The analytical results of isolated componet using GC/MS and NMR proved that the allelophatic substance in the ginkgo leaf wastes is catechol; one of phenol compounds. Based on the experiences current study, a practical method for the testing of allelophatic effect of crude extract of some materials was proposed. In this method, rice seeds were allowed to sprout until the length of coleoptile to reach 0.5 mm. Such seedlings were submerged in the solution containing supposedly allelophatic substance and the length of shoot and root was measured 3 days after treatment.

Highway design speed is a very important design element which determines highway design level. When determining highway design speed, one would estimate it utilizing the most likelihood of design speed and vehicle operating speed relationship. Existing operating speed prediction models only include highway geometric characteristics and their impacts on speed, which usually can not consider the impact of highway design speed on surrounding roadway environment and land use pattern. If this happens, excessive highway construction cost and huge environmental impact can occur. In this research project, a new vehicle operating speed prediction model was developed which can reflect the effect of surrounding roadway environment into vehicle speed prediction. The followings are the research findings : Firstly, highway terrain types and land use pattern on national roads were classified and integrated into drivers' visual recognition pattern. This was performed using a data management software. Secondly, the developed highway terrain types and land use pattern were related to vehicle speeds and it was found that there were significant statistical differences among vehicle speed for each different terrain and land use pattern. Thirdly. the General Linear Model analysis was employed to analyze the effects of highway geometric features, terrain types, and land use patterns. For two-lane highway and four-lane highway tested in this research project, it was found that R squares were 0.67 and 0.85, respectively. Additionally an optimal highway design speed range table, based on this research project. was proposed for practical use. This table can be reliably used on South Korean national road design, but discretion is required for applying this table to other types of highways including provincial roads and municipal roads.

Interactive Video Service(IVS) is a new type of media service that enables users to interact with others in the process of casting and watching videos in a system. 'Timing flexibility', which divides IVS into real-time IVS and non-real-time IVS, is one of the significant factors of interactivity. The objective of this study is to identify critical factors of interactivity in IVS and to compare their effects in terms of timing flexibility. To achieve the objective, prior literature has been reviewed to establish a theoretical framework, and twelve active users of IVS have been interviewed to develop research model of IVS. Finally, an online survey has been conducted to verify the research model. The results indicate that Technical Factor, Communication Factor, and Contents Factor of IVS are found to be the important interaction factors in IVS; and their impacts on the intention to use IVS were found to be affected by timing flexibility. This paper ends with theoretical and practical implications of study results.
