The purpose of this research presents a method to position and makes the structure for eco-corridors reasonably with collectable analysing results of various effects shown in mammals' road-kill at 429 points. Target animals of this research are Leopard cat, Siberian weasel, Raccoon dog, Korean hare, Eurasian red squirrel, Siberian chipmunk and Water deer. The results derived from the empirical analysis on the contents above are followed. First, according to the results as for Leopard cat road kill analysis, which is designated as Endangered Species Class II, the eco-corridor might be located at near village having stead food in order to decrease the frequencies of road-kill, because its road kill points were mainly collected at 4 lane hilly road with mountain-road-farm area geological type of. Second, because Siberian weasel's road kill was detected at 2 lane hilly road with mountain-road-stream geological type, the eco-corridor might be located at near a mill to decrease road-kill frequencies. Third, the road-kill frequency of Eurasian red squirrel can be reduced when the eco-corridor is located at the area across coniferous tree near 4 lane west sea freeway with mountain-road-mountain. Fourth, the road-kill of Raccoon dog can be reduced when the eco-corridor is located at 4 lane mountain road or hilly road with the geological type having farm land-road-mountain(stream). Fifth, Korean hare's road-kill can be reduced when the eco-corridor is located at grass land across ridge line of mountain, because wild rabbit road kill was happened at 4 lane mountain road or 2 lane mountain road(mountain-road-mountain). Sixth, As for Siberian chipmunk, the eco-corridor might be located at the side slope of mountain road at 2 lane mountain road under the speed of 60km/h with mountain-road-mountain. Seventh, For Water deer, the eco-corridor might be located at 4 lane hilly road with mountain-road-farm land. As for Common otter, Amur hedgehog, Yellow-throated marten, Weasel, it is difficult to specify the proper site of eco-corridor due to the lack of data. Eco-corridors for carnivores might be well located at 4 lane hilly road or 2 lane hilly road with mountain-road-farm land, and the track for herbivores might be well located as a overhead bridge on mountain-road-mountain type across mountains. In order to position eco-corridors for wildlife properly, we have to research animal's behavior with ecological background, and to consider the local uniqueness and regularly collect the empirical road-kill data in long term 3 to 5 year, which can be the foundation for the more suitable place of wild life eco-corridors.

To improve the practicality of 'Early warning service about agrometeorological weather hazards' and operation efficiency to deliver site-specific about a lot of land unit possibility of weather hazard occurrence with the suitable counterplan to farmer, site-specific early warning service system that was built at the National Academy of Agricultural Science in Korea passed some of the error supplementation and service's stabilization stage during operation period for trial services from October 2014 to March 2015. Field service system covered about 470 volunteered farmer and 950 lots in Seomjin river downstream areas (part of Gwangyang-si, Hadong-gun, Gurye-gun). This system (Two track system) consists of early warning system (a lot of land unit) to inform farmer by individual text message and dispersal prior alert system that can see the jurisdiction's situation of local government. Individual text message about Seomjin river downstream that is our first study area was launched since $2^{nd}$ March 2015, and online site (http://www.agmet.kr) started business since April 2015. Service offers currently information of farm weather, farm weather hazard, nationwide weather risk and special weather alert, also our system will consistently expand the service target area and contents and improve the service quality until 2017 when our study finished. To prevent crops damage that was caused by crisis situation like farm weather and weather damage offer prior alert about agrometeorological weather harzard to volunteered farmer, thereby our study expects to help the reduction of farm's damage caused by weather derivatives.

Recently, the Internet Protocol Television (IPTV) services have become very common, enabling various Internet-based services as well as watching TV. In the IPTV system, a Set-Top box (STB) plays a key role as a network terminal device that transmits and receives realtime multimedia contents. In addition, the IPTV networks are usually supported by broadband optical fiber-base network such as fiber-to-the-home (FTTH), However, a general IPTV STB is regarded as one of the local area network (LAN)-attached devices while sharing the bandwidth of the LAN (e.g., Ethernet). In order to overcome the limited bandwidth utilization by fully facilitating the broadband bandwidth (e.g., 1 Gbps) of the optical fiber-based network, we propose a new FC (Fiber Channel)-embedded IPTV STB which can be directly attached to the optical fiber network. Then, we verify that the impacts of the proposed FC-embedded IPTV STB by organizing the the FC-AL (Fiber Channel-Arbitration Loop) network equipped with the FC-embedded IPTV We measures the average Start-up Delay, Average Reject Ratio and the Number of Concurrent Users through extensive simulations to investigate the performances of the suggested FC-AL-based IPTV network. Surprisingly, the IPTV network architecture with the proposed FC-embedded IPTV STBs has an excellent average start-up delay of less than 10 msec, an acceptable average reject ratio of less than 3 % as well as a linear increase of the number of concurrent users when extending the architecture. This reveals that the proposed FC embedded STB has a superior impacts on the performance of the entire IPTV network by effectively utilizing the broadband bandwidth of the fiber optic-based network.

In this thesis, I intend to study the translational and clinical interpretation through the theory of Eum-Yang-Li-Hap', and reached the following conclusions. 1. 'Eum-Yang (陰陽)' in title, means Yin and Yang as method of understanding nature or humanbody, and 'Li-Hap (離合)' in title, means classification and getting together. Especially there are a view that Eum Yang in title means only meridinans within the limit of human body, but the limit needn't, because the word 'Li-Hap of 3Yin-3Yang (三陰三陽之離合)' as meaning of human meridians in the text. 2. The content of the text is generally seperated into 3 parts, the 1st part contents properties of Li Hap of Yin and Yang. 2nd and 3rd parts content the explanation of property of 3Yin and 3Yang, as example of human meridians with local conception, and content nicknames of 3Yin-3Yang and present the Ideo of 'Kae-Hap-Choo (開闔樞)'. 3. 3Yin-3Yang in the text, many of annotators tried to explanate by three types of conception, of human meridians, of the 'Viscera-Bowels (臟腑)', or of the 'Element motions and Natural factors (運氣)'. I think that these three conceptions could be mixed when the text was written, and regarde for the present that 3Yin-3Yang is explanated by the conception of human meridians. 4. 'Eum (陰)' the head-letter of the nicknames of 3Yin-3Yang, I think that it means 'Jok-Gyeong (足經)' related with the words 'The earth belongs to Yin (地爲陰)' in the text. And it i s considered that further studies should be followed on the tail-words of 3Yin-3Yang's nicknams. 5. Kae-Hap-Choo, Used in similitude" as 'Li (離)' of 3Yin-3Yang, are seperated functions by location of 3Yin-3Yang. In text 'Tae-Yang (太陽)' and 'Tae-Eum (太陰)' act as 'Kae (開)', 'Yang-Myeong (陽明)', and 'Gweor-Eum (厥陰)' act as 'Hap (闔)', 'So-Yang (少陽)' and 'So-Eum (少陰)' act as 'Choo (樞).' But there is other theory that Gweor-Eum act as Choo, and So-Eum act as Hap. 6. The theory of Kae-Hop-Choo, including only Jok-Gyeong being main materials of 'Yook Gyeong-Byeon-Jeung (六經辨證) had influence on development of clinical studies. If the theory of Kae-Hap-Choo receives and unions the ideos of '3 burning-Spaces (三焦)', metabolism, etc. more development of medicine is expected.

The statistical indexes such as RMSE (Root Mean Square Error), Mean Bias error, and IOA (Index of agreement) are used to evaluate 3 Dimensional wind and temperature fields predicted by operational meteorological model RAMS (Regional Atmospheric Meteorological System) implemented in CARIS (Chemical Accident Response Information System) for the dispersion forecast of hazardous chemicals in case of the chemical accidents in Korea. The operational atmospheric model, RAMS in CARIS are designed to use GDAPS, GTS, and AWS meteorological data obtained from KMA (Korean Meteorological Administration) for the generation of 3-dimensional initial meteorological fields. The predicted meteorological variables such as wind speed, wind direction, temperature, and precipitation amount, during 19 ∼ 23, August 2002, are extracted at the nearest grid point to the meteorological monitoring sites, and validated against the observations located over the Korean peninsula. The results show that Mean bias and Root Mean Square Error are 0.9 (m/s), 1.85 (m/s) for wind speed at 10 m above the ground, respectively, and 1.45 ($^{\circ}C$), 2.82 ($^{\circ}C$) for surface temperature. Of particular interest is the distribution of forecasting error predicted by RAMS with respect to the altitude; relatively smaller error is found in the near-surface atmosphere for wind and temperature fields, while it grows larger as the altitude increases. Overall, some of the overpredictions in comparisons with the observations are detected for wind and temperature fields, whereas relatively small errors are found in the near-surface atmosphere. This discrepancies are partly attributed to the oversimplified spacing of soil, soil contents and initial temperature fields, suggesting some improvement could probably be gained if the sub-grid scale nature of moisture and temperature fields was taken into account. However, IOA values for the wind field (0.62) as well as temperature field (0.78) is greater than the 'good' value criteria (> 0.5) implied by other studies. The good value of IOA along with relatively small wind field error in the near surface atmosphere implies that, on the basis of current meteorological data for initial fields, RAMS has good potentials to be used as a operational meteorological model in predicting the urban or local scale 3-dimensional wind fields for the dispersion forecast in association with hazardous chemical releases in Korea.

With the development of the domestic character industry, the interest in public characters has also been increased as like the characters of industrial contents. The public character is a non-commercial character implicitly expressing the symbolism shared or directed by members of the specific region, organization, organization, organization, or event. It has been distinguished from commercial design, aiming the profit for a specific person or group, and it has been given the role coincided with the purpose of public design, pursuing social value such as citizens' happiness, happiness in the subject and object, aiming value and role of design. Public characters has been grown around the local government character development, but most of the characters were not practically utilized. However, as interest in public characters has been increased, those have been received worm welcome again as a means of expressing the uniqueness and identity of the region. In this paper, we have tried to study the expression of identity of public character by substituting the site-specificity. The site-specificity is referring the art of the time that focuses on the region in contemporary art, a work in which the meaning is created by a specific region and situation. Currently, as a main role of public character is representing the region or the institution, its identity and value can be judged by the community it belongs. Through this, it is intended to study the social meaning of the character in the region as a public design.

Ballast water filled into and discharged from the ballast tank of a ship has a negative impact on local marine environment due to various aquatic organisms contained therein. The IMO developed and adopted "The International Convention for the Control and Management of Ships Ballast Water and Sediments, 2004" with the purpose of protecting the marine environment from transfer of harmful aquatic organisms in ballast water carried by ships. The IMO BWM Convention was approved in September 2016 and ships must be equipped with ballast water management system after September 2017. Ships' ballast water treatment methods are divided into using active substances as electrolytic type, ozone type, chemical dosing type and using physical treatment type as filter type, ultraviolet type. It is also used with a combination of two methods. Electrolysis is superior in terms of cost and efficiency. In this study, basic principles, components, and land base test contents of electrolysis ballast water treatment system, a direct electrolyzed ballast water treatment system, were examined. Land base test was conducted with 300m3/h capacity device at the KIOST Geoje plant where the government test facility was installed. This test validated that the system meets IMO standards.

A Library is the fundamental character of culture in a country and it is also a barometer of culture in its community. Every cultural reality, however, can hardly come to fruition in a short time and so, it will be effected through a long time and tradition. This study aims at catching up how the above-mentioned public libraries have an influence on culture of its community people. For this purpose, the actual conditions of the public libraries have been investigated and analyzed and as a result of it, the problems have been reilluminated from the nation-wide point of view. And in the new changes, developing improvement measures have been tried to find. How to study was on the basis of the actual materials of the on the-spot survey, the interviews with the working officials and the response by way of questionnaire. Summing up the investigated and analyzed contents are as followings. In the above mentioned province, therefore, number of the public libraries are very limited compared with number of the people. And so, it is very essential to increase the public libraries in the province. In terms of the actual conditions, the public libraries lags far behind the other provinces in Korea from this library field. The present chronic conditions are the budgetary deficit, the collections insufficient to the legal minimal standards, the lack of professional librarians ignorance of the people and library managements by unprofessionals, etc.. This hinders the progress of the public libraries and to seculate them from the people. The improvements and the solutions to the above-mentioned problems are as follows. 1. To recruit the personnel sufficient to the legal standards and to reorganize the offices and to turn upward the highest class of librarian's position above the 4th class. 2. To secure collections sufficient to the legal standards and to strang then the extension services. 3. To organize the council composed of the chief librarians of the public libraries including the working chiefs in the province and to develop the works-in-hand of the libraries from the level of decision-making. 4. To organize the librarian training group and to study the working problems and to seek the qualified improvement of librarians. 5. The management of the public libraries in the province are, at present, der the Ministry of Education and the local government takes the financial power. So both should be shortly unified. 6. To do regularly the course of how to use library materials for the community people and to seek the inducement measures for the people through the various cultural events. 7. The public libraries organize the mutual cooperation networks and to seek the system automatized plans of free use of library materials and every library works. 8. To enlarge book mobile system actively and to infiltrate into the daily living of people deeply. Finally, what the present writer would like to speak to the chief librarians of the public libraries the human aspects of librarians should not be ignored no mater how excellent a library organization may be. In addition to this, the present writter is sure that the far-reached future of our library organization will depend on the librarians.

This survey was conducted to investigate the factors affecting the chemical components of groundwater in the plastic house area cultivated with horticulture crops. The data were evaluated with depth of groundwater, topography and years of cultivation as major factors. $NO_3-N$ content of groundwater was higher at waterside(Alluvial plain) than Inland plain(Alluvial plain), local valley & fan or mountain foot area, and also was detected the highest concentration in 6-10m depth well. The contents of $NO_3-N$ and $SO_4{^{2-}}$ in groundwater were increased with cultivation years. The ionic composition (${\sum}A/{\sum}C$ : ratio between total equivalant of anions and cations) of groundwater decreased with depth and was higher at waterside(alluvial plain) than other topography. The $NO_3-N$ content was negatively correlated with pH whereas it was positively correlated with $SO_4{^{2-}}$, $Cl^-$, $K^+$, $Ca^{2+}$, and $Mg^{2+}$.
