The complementary relationship-based evapotranspiration models, namely, AA model of Brutsaert and Stricker (1979) and the CRAE model of Morton (1983) was applied to two permanent stream watersheds Jeju island for the first time, and their major optimal parameters were suggested in this study. The representative watersheds for model calibration and validation were selected as the Hancheon watershed located in the northern part of the Jeju island and and the Kangjeongcheon watershed in southern Jeju island, respectively. The estimated actual evapotranspiration for the Hancheon watershed was compared with the result by the hydrological model, and the major parameters of the AA and CRAE models were calibrated until their results match the hydrological simulations. Through the iterative estimations, the optimal parameters were determined as ${\alpha}=1.00$, $M=30.0Wm^{-2}$ of the AA model, and $b_1=33.0Wm^{-2}$, $b_2=1.02$ of the CRAE model. The calibrated AA and CRAE models were applied to the Kangjeongcheon watershed for model validation, and it was found out that both models can accurately produce the actual evaporation on annual and semiannual bases.

Within the last several years, there has been a large number of algorithms developed for face recognition. The majority of these algorithms have been view- and projection-based algorithms. Our definition of projection is not restricted to projecting the image onto an orthogonal basis the definition is expansive and includes a general class of linear transformation of the image pixel values. The class includes correlation, principal component analysis, clustering, gray scale projection, and matching pursuit filters. In this paper, we perform a detailed analysis of this class of algorithms by evaluating them on the FERET database of facial images. In our experiments, a projection-based algorithms consists of three steps. The first step is done off-line and determines the new basis for the images. The bases is either set by the algorithm designer or is learned from a training set. The last two steps are on-line and perform the recognition. The second step projects an image onto the new basis and the third step recognizes a face in an with a nearest neighbor classifier. The classification is performed in the projection space. Most evaluation methods report algorithm performance on a single gallery. This does not fully capture algorithm performance. In our study, we construct set of independent galleries. This allows us to see how individual algorithm performance varies over different galleries. In addition, we report on the relative performance of the algorithms over the different galleries.

The purpose of this study is to consider the relationship between point of view and prospect behavior occurring in the experience of a painted landscape. This study analyzes one hundred scenes from the 'real landscape painting' by Kyumjae, one of the most famous landscape painters in 18th century Korea. The results of the study are as follows: 1. It clarified that Kyumjae's real landscape painting's 100 scenes have many view points such as roads, bridges, pavilions, mansions, towers, terraces, hillsides, bases of mountains, broad flat roots, brooksides, and ferries that are apt to occur in the experience of a landscape. The spatial characteristics of view points are expanded fields of vision, evening and night scenes, edges of landforms and structures from which to improve ones vantage point. 2. It showed that 99 out of real landscape painting's 100 scenes depict a view point'to look'and 79 of 'to look through', 73 of 'look around'and 24 of 'to look over'. 3. It showed that real landscape painting's 100 scenes depict that the view point 'to look' is mainly upon a road from which people are looking over an elevated landscape such as the top of a mountain or rockwall. The view behaviors of looking down are depict 15 pavilions, 14 mansions, 2 broad rocks and 10 mountain tops on which people experience landscapes such as fields, rural communities and streams. The view behaviors to look depict 33 ships, 24 roads, 24 pavilions, 19 mansions and 12 terraces on which people experience landscapes such as distant views of mountains, rivers and landscapes. The view behaviors to look around to obtain orientation of landscape are depict 16 pavilions, 10 mountaintops. To glimpse on the way of journey depict 33 ships and 29 roads. To look over depict 11 mansions and 6 pavilions on which experience borrows the landscape. To look through landscapes such as rivers, mountains and rockwalls depict 15 roads, 14 pavilions and 11 mansions. To exchange looks depict 30 ships, 14 roads, 12 pavilions and 12 mansions. We expect that these results might give clues toward the experience of landscapes and the practice of landscape design methods which select viewpoints, and in the design of view points suitable to prospect behaviors.

Coastal settlements have a diversity of tangible or intangible local assets and are environmentally sensitive areas. The value of tangible or intangible local assets is often overlooked and there is no enough consideration for the inhabitants who have a various and acute stake in the development process of coastal settlements. The development of coastal settlements without consideration for the local circumstance, resident's needs, and local characteristics makes it difficult to achieve sustainable regeneration. There are also alienation, conflicts, and the loss of a authentic sense of place because of physical oriented development without regard to the social, economic, and cultural aspects. This research defines the components and types of coastal settlements and draws the characteristics of them around the fishery ports in Busan in the aspect of sustainable regeneration. It will be the important methods for an integrated regeneration including not only spatial and physical regeneration but also social and economic regeneration which has the preservation of local culture with living conditions, local economy activation, and community building. It will also provides the bases of sustainable development, attractiveness, and competitiveness of coastal settlements.

Being able to resolve huge problems deriving from integration of information systems in-house or business to business, the web service that uses the XML standard technology has recently taken a quick dominance the next generation e-business bases. It's one constant concern how to integrate, change, and maintain such systems as based on certain technologies according to the changes to information technology, which is on the ongoing process of evolution. To help solve those problems, OMG suggested a new software architecture called MDA(Model Driven Architecture). MDA runs a process that establishes a platform independent model(PIM), which is an analysis model used as part of the existing development procedures, and automatically converts it into a platform specific model(PSM), a design model, based on the established PIM. Such automatic conversion has lots of benefits including easy support for diverse platforms, reducing the coding time that usually consume a great deal of the developer's effort, and facilitating quality control in the aspect of development processes. By applying the MDA development process to a new web service development, you can choose web service as the target platform at the PIM of MDA and express PSM with a web service model, WSDL. This study set out to classify the web service development or integration processes by the provider md requester to identify the types of web service development processes, and to apply the MDA development process to web service development, thus suggesting a new kind of web service development process that can be referred to by both the web service provider and requester.

In order to answer the questions successfully on behalf of the human in DeepQA environments such as Jeopardy! of the American quiz show, the computer is required to have the capability of fast temporal and spatial reasoning on a large-scale commonsense knowledge base. In this paper, we present a scalable spatial reasoning algorithm for deriving efficiently new directional and topological relations using the MapReduce framework, one of well-known parallel distributed computing environments. The proposed reasoning algorithm assumes as input a large-scale spatial knowledge base including CSD-9 directional relations and RCC-8 topological relations. To infer new directional and topological relations from the given spatial knowledge base, it performs the cross-consistency checks as well as the path-consistency checks on the knowledge base. To maximize the parallelism of reasoning computations according to the principle of the MapReduce framework, we design the algorithm to partition effectively the large knowledge base into smaller ones and distribute them over multiple computing nodes at the map phase. And then, at the reduce phase, the algorithm infers the new knowledge from distributed spatial knowledge bases. Through experiments performed on the sample knowledge base with the MapReduce-based implementation of our algorithm, we proved the high performance of our large-scale spatial reasoner.

From foreign and/or domestic investors' perspectives, it may be interesting to find any financial attributes or profile of the firms headquartered in 'Chungcheong' province concerning profitability, given that this subject so far drew less attention in the previous literature. This study performed three hypothesis tests on the profitability indicator by utilizing the models such as the 'panel data' one and the 'logistic' regression one, applying a modified 'Dupont' system. With respect to the major findings, the results identified that the proxies measuring leverage across the book-value(BVLEV1) and the market-value(MVLEV1) bases, were statistically significant constituents determining profitability. Another explanatory variable, SIZE, with its positive and statistically significant relationship to the indicator, represented that the firms in the province were smaller than their counterparts in the other regional areas in Korea. DRELY applying a modified 'Dupont' system, found to be the only statistically significant discriminating factor between these comparison groups. As one of the primary contributions of this study, the outcomes may be used by the financial institutions operated across the regions including Seoul Metropolitan area, when implementing their lending practices to provide funds for potential borrowers such as the firms belonging to 'Chungcheong' province.

The purpose of this study was to measure the changes in soil properties and forest vegetation after surface fire, which had occured on June 5, 1983 in Mt. Gwanag, Kyunggi-do. Moisture content, organic matter and acidity of soil increased just after the fire and then dropped down up to those of unfired areas as time goes. Also total nitrogen, available phosphorous exchangeable base had the similar trend to moisture, organic matter and acidity. Most of the exchangeable bases in surface soil except for sodium were higher than those in sub-soil. No changes in soil texture by the fire were found. Increasers, decreasers, invaders and neutral species could be classified according to the relative importance value of each species. Species diversity was reduced just after the fire and increased gradually afterward. Diversity in the southeast slope was higher than that in the southwest slope. Due to the fire, evenness of woody plants decreased continuously while that of herbs increased. Species similarity was shown greater at fired areas than at unfired areas.

This study analyzes the Trinitarian principles of Christian education through the neo-orthodox theology of Karl Barth, Reinhold Niebuhr, and Paul Tillich in the current era of postmodernism. Both neo-orthodoxy and postmodernism react against the epistemological ideals of modernity. Postmodernism is based on a limited human point of view, and thus becomes a captive to its own subjectivity, producing two main characteristics - pluralism and relativism. Since neo-orthodoxy appeared as a reaction against human-centered modernity, critical analysis of neo-orthodox theology can give insights to cope with the challenges of postmodernism in Christian education today. Thus, this study bases its argument critically on the thoughts of neo-orthodox theologians such as Karl Barth, Reinhold Niebuhr, and Paul Tillich, since they responded to the challenges of enlightenment through rediscovering fundamental theological principles. First of all, this study examined the meaning of God's creation and the fall and provided the principle of theistic relativism. Secondly, this study explored educational insights from Jesus' crucifixion, through His work of redemption, liberation, and restoration and suggests an incarnated relationship building. Thirdly, the study analyzed the caring and comforting work of the Holy Spirit and emphasized the power of the Holy Spirit that heals corrupted human reason and enables loving relationships.

The axial ligations of nitrogenous bases (pyridine, imidazole, 1-methylimidazole and 2,6-lutidine) to Zn(II)-, Cu(II)-, and Ni(II)-tetrakis(o-chlorophenyl)porphyrin(o-ClTPP), and -tetraphenylporphyrin (TPP) were investigated in organic solvents $(CH_2Cl_2,\;C_6H_6,\;CH_3NO_2,\;(CH_3)_2CO,\;CHCl_3,\;DMF\;and\;DMSO)$ and at 0.01M of ionic strength. The equilibrium constants for the ligation reactions of methalloporphyrins were determined using spectrophotometric method at 15∼35${\circ}C$. In case of M(II)-TPP the equilibrium constants K were considerably larger than those of M(II)-(o-Cl)TPP, depending on steric effect of the porphyrin. The linear relationships between logK of the axial ligation and $pK_a$ of nitrogenous base were shown in M(II)-TPP, but not in M(II)-(o-Cl)TPP. The stabilities of MTPP(L) were controlled by the reation enthalpy and entropy, while those of M(o-Cl)TPP almost by the reaction entropy. The coordinating power of solvent to the methalloporphyrin were also studied in $CHCl_3,\;(CH_3)_2CO$, DMF and DMSO. From those results the solvent effects on the equilibrium constants were discussed.
