  • Main debates in the modern geographical thoughts had been developed around the regional geography. Because regional geography had been regarded as a raison d'etre of geography, it remains solid status in geography curriculum. But unscientific nature of regional geography was the main problem of modern geography. Modern geography has developed the logical legitimation of regional geography, instead of research procedures. We examine the logic of modern geographical thoughts from 3 worldview. Here we represented the part - the whole relationship as the primary category, and classify these into three type according to the implicit proposition about the relationship. One is the organic view, which assume that the whole is greater than the sum of the parts. This view was the primary proposition held by the modem geographers. This view regarded the region as organic complex, and presume the unit region which is irreducible to the elements. The other is mechanic view, which presuppose that the whole is the sum of the parts. This view comprehend region by means of spatial order, in order to simplify the complex reality. Then we compare real condition with assumption. These two view held static assumption. Now, the third view regarded the part- the whole relationship as being dynamic. Most geographers held the organic view, although someone suggests the idea of harmony, the others suggests the idea of complex. But these view presumes the pre-industrial society in which the genre de vie was main principle of social order. Therefore It could not comprehend the regional concept in the context of the urbanization and industrialization.

  • Rock slope has a variety of irregular discontinuities and represents a discontinuous mass. Rock joint plays an important role of control hydraulic and mechanic movements in the rock mass. These characteristics between hydraulic and mechanic movements at the rock joints could be represent difference. Therefore they are quiet important factor for slope design. In this study the weathered rock slopes were carried out to analysis of slope stability and geophysical survey. The electrical resistivity survey with dipole-dipole array conducted five profiling sites, and SWEDGE and SLIDE for slope stability analysis were applied on 20 rock slopes far assessment of slope stability and understand to geological situations due to the weathering.

  • PM10, which is below 10 ${\mu}{\textrm}{m}$ in a diameter, has a high deposition in the lung or the bronchus by breathing and is generally composed of a lot of organic matters, viruses, algae, mold, and metallic elements that are very toxic to people. This study identified the characteristics of concentration of PM10 and air-borne jmetallic elements produced in the industrial city, Ulsan, and analyzed the correlatuion between sources and generation patterns of PM10 and metallic elements. We classified the five areas(green, residential, heavy traffic, mechanic, and petrochemcal and non-ferrous metal) which might have different characteristics of sources of PM10 and metallic elements. The average concentrations of PM10 in the five areas were as follows(petrochemical and non-ferrous metal(99.9$\mu\textrm{g}$/㎥)>mechanic(77.5 $\mu\textrm{g}$/㎥)>heavy traffic(47.1 $\mu\textrm{g}$/㎥)>residential(39.3 $\mu\textrm{g}$/㎥)>green(32.8 $\mu\textrm{g}$/㎥)). Those of petrochemical and non-ferrous metal areas were higher than other areas. In this study, the average concentration trend of metallic elements contained in PM10 are shown as follows: Fe>Zn>Pb>Cu>Mn>Cr>As>Cd>Sn>Hg, respectively. The metallic elements identified in PM10 showed the highest concentration in the petrochemical and non-ferrous areas. Metal combinations showed that a high correlation among concentrations of heavy metals were as follows: As, Cd and Fe in the residential area; Zn, Mn, Cu and Pb in the mechanical area; and Zn, Cu, As, Pb in the petrochemical and non-ferrous industrial area.

  • In order to check the status of tire wear, a driver or auto mechanic generally checks tires with the naked eyes or with a coin. Those are easy for anyone but make it difficult to obtain precise information. But the result is a measure of mechanic wear out due to subjective judgment. Since we can not give correctly measure the stability of the tire. This may lead to an accident of the operator. Therefore, there is a need for a system checking tires precisely, accurately and easily, while making up for the aforementioned defect. This thesis has implemented a system with the aforementioned function. This system tire surface scanner data unit to determine the tread wear on the car and a storage unit for the data save, And a Web service unit allows the user to easily check the information.

  • The purpose of this study is to determine the optimal mix ratio of Maneul-Sulgi and thereby, review its availability as health cake. For this purpose, the ratios of garlic juice and powder were varied with sugar added. As a result of quantitative descriptive analysis, it was found that the more the garlic juice and powder were added to non-glutinous rice, the Garlic taste was stronger. On the other hand, the less garlic powder was added, the cake would taste softer, and the less garlic juice was added, the cake was more chewy and moist. The feeling after swallowing was best when the ratio of garlic juice was $7\%$. As a consequence of surveying the tastes of Maneul-Sulgi, it was found that the less garlic powder was added to non-glutinous rice, the cake was more preferred. It was perceived that the ratio of garlic juice should be $7\%$ for flavor and desirable taste. As a result of testing the mechanic characteristics, it was found that the less garlic juice was used, the cake was more hard, elastic, cohesive, viscose and chewy. The more garlic powder was used, the Adhesiveness was higher. The Overall acceptability of sensory examination for Garlic taste had positive correlation Hardness of sensory examination and mechanical examination for adhesiveness.

  • RFID is a generic term for technologies which use RF waves to identify, track, or categorize any object. A radio frequency identification (RFID) reader recognizes objects through wireless communications with RFID tags. Tag collision arbitration for passive tags is a significant issue for fast tag identification due to communication over a shared wireless channel. One of the research areas in RFID system is a tag anti-collision protocol. In this paper, various anti-collision protocols are discussed. The pros and cons of different anti-collision protocols are compared with each other and their performance is analyzed and the better performance anti-collision protocol is suggested.
