The main purpose of this thesis is to select the appropriate plants for the ecological restoration of coastal land. The soil and vegetation environment survey of the beach where the halophytes live now was executed for the sake. Firstly, the soil survey was done by the physical and chemical survey of beach soil and dumped soil. The soil is mostly sandy loam and sandy clay loam which has silty much. The beach soil where the salt plants live has more organic matters in the content than dumped soil because of the influx of the dead halophytes, a pioneer plant to this area. Secondly the vegetation survey was executed by the halophytes survey in the beach area in order to select the appropriate plants for ecological restoration. The shows two different areas in the vegetation divided by the salt density of soil. Artemisia fukudo, Juncus haenkei, Carex pumila, Silene armeia, Polyponum aviculare etc live in the less salt density area and it doesnt show collected. Salicornia herbacea, Suaeda asparagoides, Aster tripolium, Limonium tetragonum, Suaeda maritima, Scirus fluvitilis, Phragmtes communis, Suaeda japonica, Zoysia sinica etc halophytes live in the more salt density area and there are a few advent plant but many collected. So the salt density of soil limits the vegetation. The selection of appropriate plants for the ecological restoration programs was designed with 3 different standards considering the salt density of soil in the dumped soil area. The plan selection guidelines of thick salt density due to the salt density of soil, and economical efficiency and maintenance because the area is large. The guidelines of middle salt density area were made considering economical efficiency and maintenance because there are salt as well, and it is effective for the scenery if they have normal ecology but their leaves have good color and the flowers are beautiful. However I suggest beautiful flowery plants for the neutral plan area because this area is the entry point of the airport so the view is very important.

본 연구는 생태학적 위기와 회복의 과제 앞에서 기독교교육의 역할을 몰트만의 창조론의 관점에서 재고한 글이다. 인류는 여러 차례의 산업혁명을 거치며 산업상의 획기적 발전을 이루어 왔다. 그러나 그로 인해 생태계는 심한 몸살을 앓으며 이상 현상을 드러내는 지경에 이르렀다. 이러한 생태계의 파괴와 고통에 대하여 기독교교육은 자연 세계를 향한 생태학적 감수성을 보다 통전적으로 접근하고 실제적 대안을 제시할 필요가 있다. 몰트만은 오늘날 점증하는 자연에 대한 인간의 착취는 세계가 인간의 소유라는 인간 중심적 생태의식에서 비롯되었다는 점을 상기시킨다. 그러면서 하나님 중심의 생태학적 세계의식으로 전환할 것을 제시한다. '창조공동체', '삼위일체 하나님의 사귐', '안식일을 통한 종말론적 새 창조'는 하나님 중심의 생태학적 세계의식을 집약해주는 주요 개념들이다. 이러한 몰트만의 창조론을 기초로 본 글은 기독교교육이 추구해야 할 생태학적 감수성을 성례전적 창조공동체의 관점에서 살펴보며 기독교교육의 역할과 실천적 대안을 검토하였다. 이를 통해 인간을 포함해 세계는 인간의 소유가 아니라 자연의 일부로서 종말을 향해 함께 지어지며 하나님의 영광을 드러내는 성례전 공동체임을 보여주었다. 더불어 기독교교육은 하나님의 사귐 안에서 사람과 세계의 화해적 사귐을 중재하는 고난받는 주체가 되어야 할 것을 제안하였다. 하나님의 창조를 경축하며 종말론적 창조의 완성을 지향하는 안식일 지킴이 교육은 무너진 생태계의 회복을 위해 기독교교육이 실천할 수 있는 실천적 영역이 될 것이다. 몰트만의 창조론은 그동안 기독교교육이 간과하거나 외면했던 생태환경에 관한 관심과 더불어 생태환경을 복원하기 위한 통전성 있는 기독교교육적 통찰을 제공한다는 점에서 의의가 있다.

The use of fly ash in cement and concrete industries has many benefits including engineering, economic, and ecological aspects. However, it has a disadvantage of low strength development, especially at early ages. In this study, in order to overcome this problem, the early strength accelerating agent($NA_{2}$ $SO_{4}$) was selected and applied to the production of high strength concrete(HSC) containing fly ash. It was found that the compressive strength of fly ash concrete incorporating TEX>$NA_{2}$ $SO_{4}$ has greater than that of concrete containing fly ash only until 7 days after casting. From the microstructural point of view, ettringite increased and pores decreased in fly ash concrete incorporating TEX>$NA_{2}$ $SO_{4}$ , leading to the development of early age strength. It was also found that the velocity vs. strength relationship of HSC is considerably different from that of low-strength concrete(LSC). Therefore, in order to predict early age strength of HSC, a estimation equation different from that for LSC is needed.

The research on potential energy was conducted to conserve the high-exergy energy like primary energy and utilize waste heat from sewage. From the Point of view in using the waste heat, the energy Potential of waste water from the model house was simulated. From the results, when the heated water was supplied to the model house side in order to put unused energy to Practice use, heated water had higher energy Potential than unheated water, which was due to the discharge of most of unused energy. The possessing heat capacity of sewage from heated water was increased to 40-70 percents in comparison with that from the unheated water. Therefore, it can be used as energy source for improving coefficient of performance of heat pumps. By adopting the multiple heat pump into a model house, It showed that the possessing heat capacity of sewage was reduced. It was also found that the heat was recovered as energy source fur multiple heat pump in a model house.

The purpose of this paper is to propose a novel modeling approach called Services Ecosystem that applies the concept of ecosystems in ecology to Service-Oriented Software Development and Integration. For this purpose, an ecological system for software systems is proposed for the emerging Service-Oriented Computing paradigm, describing how participants interact with each other within their environments. Three emerging concepts, Service-Oriented Programming, Software Factories, and Service Grid, are employed to explain biotic and abiotic environments. Based upon the Services Ecosystem model, we demonstrate Services Ecosystem Model transformations by using a case example. The Services Ecosystem model is a novel approach for envisioning the Service-Oriented Computing paradigm in terms of an ecosystem in which the roles/perspectives of each participant and their relationships/interactions to environments are clearly described with a holistic view.

The vegetation and landscape of Hokkaido were phytosociologically referred. The region of F a g e t e a c r e n a t a e on Hokkaido is divided into two types of deciduous broad-leaved forest: the oak (Quercus mongolica var. grosseserrata) forests mixed with conifers (mainly Abies sachalinensis) and the beech (Fagus crenata) forests of northernmost distribution in far-east Asia. The oak forests, which is dominated by Quercus mongolica var. grosseserrata in Japanse islands, seem to be developed from different climatic and edaphic conditions, especially in the amount and sharing pattern of precipitation in a year, and weak acid brown forest soil, volcanic ash soil and sandy soil. On the all-inclusive phytogeographical view-point, Hokkaido is situated at northernmost region of F a g e t e a c r e n a t a e (cool-temperate zone)neighboring with subarctic and subalpine vegetation, vegetation, but the evergreen broad-leaved forest (C a m e l l i e t e a j a p o n i c a e, warm-temperate zone) is abscent.
