This paper tries to explore the local uniqueness and evolutionary characteristics of the spatial structure of the rural dwelling houses of China's Korean Ethnic. For this purpose, the paper selected 51 typical samples in each district, analyzing their ancestral home, building age, size, construction method, family composition etc. Moreover, the paper classified the pattern of the samples and analyzed the characteristic and evolutionary process of each pattern. Conclusions based on the analysis of the ancestral homes are as follows: 1.The house pattern of these China's Korean ethnics who are originally from the Hamkyung province is mainly jeongji- access type (A-type). A-type is mainly distributed along the Tumen River and Yalu River, in the Sino-Russian borders and the inland areas of Heilongjiang province. With the migration of the China's Korean ethnics, in Sino-Russian borders and the inland areas of Heilongjiang province, A-type with the 'badang' space, vestibule-access type (C-type) and living-centered type (D-type) appeared. 2. House patterns of Korean ethnics who are originally from the Pyongan province include three types: A-type, kitchen type (B-type) and C-type. A-type is mainly distributed along the Yalu River while B-type and C-type are mainly in the inland areas of these three Northeast provinces. With the decrease of population, the merger of rooms happened in A-type; while in the B-type and C-type, bathroom and storage came to exist in the north of the room. 3. The house pattern of Korean ethnics who are originally from the Gyeongsang province is mainly B-type, which is distributed in the inland areas of Heilongjiang and Jilin provinces. Besides, C-type and D-type also exist. They are in Jilin and Liaoning provinces. In the process of evolution, storage was set in the north part of the room or the window was cancelled in order to defend the coldness in Heilongjiang area, while in Jilin and Liaoning provinces, living room came into existence, which is gradually developing to D-type.

The purpose of this study is to discover the plans for Yangyeongsi in Daegu, one of the most traditional streets and a tourist spot in South Korea, by preserving the historical place, reviving the historical characteristics and identity, revitalizing the uniqueness of the location, and developing the environment. This paper also illustrates the problems of the place through a investigation into its current state in order to promote the district and conduct a fundamental research framework to suggest future development methods and directions based on the problem statements. Daegu Yangyeongsi was chosen through frequency analysis and a survey asking for a suitable location and local characteristics to be developed for the local promotion through the field investigation of 158 cultural assets registered in the local government. This survey was conducted through the development process of the Regional Design Innovation Center to revitalize the traditional streets and places of interest. Through this investigation, 19 sites and traditional streets, which can be cultural resources for sightseeing and contribute to the local promotion, were extracted. Yangyeongsi, was selected from the finalists. The research methodology will be 1) to identify things for improvement potentiality through an in-depth analysis of Yangyeongsi, 2)to examine the mutual relationship between the revitalization strategy of Yangyeongsi and the city promotion strategy, and 3) to integrate the problems and improvements based on the results of the analysis. The notion of SWOT analysis synthetically considering the elements of opportunity and intimidation, strength and weakness to come up with the development direction was introduced to discover the local characteristics of Yangyeongsi and deduce the problem statement through the state analysis. Based on these results, the future development method and direction will be suggested in this paper through the revitalization study of Yangyeongsi.

This study examines the epistemological approach of the economic geography and the approach in the ontology of geography which has been studied based on the region, and thereby aims at the systematization of economic geography. Since 1956, Korean economic geography study has been conducted under the development of studies in developed countries without discussing the uniqueness of the study or the systematization of the research approaches. As a result, the systematization is built after the economic geography is divided into neoclassical economy, geographical political economy, regional structure of the national economy, and local autonomous entity economy on a axis of epistemology and ontology for the systematization of approaches. We should pursue the intellectual change adding the major economic phenomena theories such as the world-system perspective, the regulation theory, network theory, and the institutionalism etc. into the systematization of the economic geography.

We consider weak solutions of the instationary Navier-Stokes system in a smooth bounded domain ${\Omega}{\subset}{\mathbb{R}}^3$ with initial value $u_0{\in}L^2_{\sigma}({\Omega})$. It is known that a weak solution is a local strong solution in the sense of Serrin if $u_0$ satisfies the optimal initial value condition $u_0{\in}B^{-1+3/q}_{q,s_q}$ with Serrin exponents $s_q$ > 2, q > 3 such that ${\frac{2}{s_q}}+{\frac{3}{q}}=1$. This result has recently been generalized by the authors to weighted Serrin conditions such that u is contained in the weighted Serrin class ${{\int}_0^T}({\tau}^{\alpha}{\parallel}u({\tau}){\parallel}_q)^s$ $d{\tau}$ < ${\infty}$ with ${\frac{2}{s}}+{\frac{3}{q}}=1-2{\alpha}$, 0 < ${\alpha}$ < ${\frac{1}{2}}$. This regularity is guaranteed if and only if $u_0$ is contained in the Besov space $B^{-1+3/q}_{q,s}$. In this article we consider the limit case of initial values in the Besov space $B^{-1+3/q}_{q,{\infty}}$ and in its subspace ${{\circ}\atop{B}}^{-1+3/q}_{q,{\infty}}$ based on the continuous interpolation functor. Special emphasis is put on questions of uniqueness within the class of weak solutions.

Fingerprints have been widely used in the biometric authentication because of its performance, uniqueness and universality. Recently, the speed of identification becomes a very important point in the fingerprint-based security applications. Also, the reliability still remains the main issue in the fingerprint identification. In this paper, we propose the fast and reliable fingerprint matching algorithm based on the process of the 'self-nonself' discrimination in the biological immune system. The proposed algorithm is organized by two-matching stage. The 1st matching stage does the matching process by the use of the 'self-space' and MHC detector string set that are generated from the minutiae and the values of the directional field. Then the 2nd matching stage is made based on the local-structure of the minutiae. The proposed two matching stage reduces matching time while the reliability of the matching algorithm is maintained.

The purpose of this study is to analyze the status of interlibrary loan (ILL) services using data from its transection. While analyzing the ILL data, agenda to improve the quality of services was identified, and suggestions were made to address them. Three data sets including National Inter-Libary Loan data, National Library Statistics System data, and local inter-library loan system analysis data were collected and analyzed. The results indicate that the size of transaction in ILL is getting bigger. The local ILL, particularly, was expanded and actively used by people. Additionally, the type of library participating in ILL networks was diverse and the number of library was increasing. Finally, this study discussed the tool to measure the contribution of each library in ILL. The collection uniqueness and collaboration index of library as well as the ILL statistics should be considered in the process of the tool development.

The inconsistent city planning damaged the city's landscape & identity, the old days. Nowadays the central and local governments are interested in the city's landscape design for residents, economic reason, etc. Color is most efficient one of design elements to improve a city landscape. So to establish the uniqueness and beauty of Gunsan city landscape, this study was performed to find out Gunsan landscape colors to survey the landscape color, by priority. There are nature environment of sea, river, reservoir, mountains and plain and artificial environment of buildings used japanese occupation period, them in early modern era and modern things. It found out the color palette has extracted from the present colors in the city landscape. There were mostly colors with low chroma, middle value and the next thing was them with high value. The blue among hue was strong. The Chroma was very low to be concentrated in $L^*$ axis. So achromatic color or blue/green of middle value and low chroma were recommended for dominant color and the similar color of former color was good for assort color in Gunsan city landscape.

Mercury (Hg) is ubiquitous throughout the earth's atmosphere. The uniqueness of its atmospheric geochemistry is well-known with the high environmental mobility and relatively long atmospheric residence time (c.a., 1 year) associated with its high chemical stability. Despite a growing recognition of the environmental significance of its global cycling, the prexisting Korean database for atmospheric Hg is extremely rare and confined to a number of concentration measurements conducted under relatively polluted urban atmospheric environments. To help activate the research on this suvject, an in-depth analysis on the current development in the measurements of atmospheric mercury and the associated fluxes has been made using the most using the most updated data ests reported worldwide. As a first step toward this purpose, the most reliable techniques commonly employed in the measurements of its concentration in the background atmosphere are introduced in combination with the flux measurement techniques over soil surface such as: dynamic enclosure (or field flux chamber) method and field micrometeorological method. Then the results derived using these measurement techniques are discussed and interpreted with an emphasis on its mobilization across the terrestrial biosphere and atmosphere interface. A unmber of factors including air/soil temperature, soil chemical composition, soil water content, and barometric pressure are found out to be influential to the rate and amount of such exchange processes. Although absolute magnitude of such exchange processes is insignificant relative to that of the major component like the oceanic environment, this exchange process is thought to be the the predominant natural pathway for both the mobilization and redistribution of atmospheric Hg on a local or regional scale.

We consider the following Dirichlet initial boundary value problem with a gradient absorption and a nonlocal source $$\frac{{\partial}u}{{\partial}t}-div({\mid}{\nabla}u{\mid}^{p-2}{\nabla}u)={\lambda}u^k{\displaystyle\smashmargin{2}{\int\nolimits_{\Omega}}}u^sdx-{\mu}u^l{\mid}{\nabla}u{\mid}^q$$ in a bounded domain Ω ⊂ ℝ^N, where p > 1, the parameters k, s, l, q, λ > 0 and µ ≥ 0. Firstly, we establish local existence for weak solutions; the aim of this part is to prove a crucial priori estimate on |∇u|. Then, we give appropriate conditions in order to have existence and uniqueness or nonexistence of a global solution in time. Finally, depending on the choices of the initial data, ranges of the coefficients and exponents and measure of the domain, we show that the non-negative global weak solution, when it exists, must extinct after a finite time.

Jeju, the biggest island in Korea, was registered as a World Natural Heritage in 2007. Recently, it was also voted as one of the New Seven Wonders of Nature. The need for academic awareness and tourist values on Jeju Island are understood. Gal-ot, one of the ten symbols for Jeju, is known for working clothes in general, despite its potential for cultural products because of its regional uniqueness and useful functional advantages. The authors conducted a comprehensive literature review and researched market trends of Gal-ot stores in Jeju to present development directions for cultural goods and to contribute to local economic improvement. Most stores were located in a semi-residential area and Jeju-si in Jeju Special Self-Governing Province. Most products were not available for sale due to difficulties in the production process and online utilization. High prices and similar color, fabric and style hurt competitiveness. Various experiencing programs of Gal-ot and persimmon dyeing were necessary to expand the main target from residents to tourists. Also, marketing strategies using the internet and design plans reflecting current trends were needed. This study would contribute to prepare developmental projects of cultural product and result in economical advantages on Jeju Island.
