This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of major 10 Asia-Pacific university libraries. The results are as follows. To begin with, Korea-related records in most university libraries are very poor except for some libraries and are generally 2 times less than Japan related records. There are even 6 times less in 2 libraries. Second, most libraries organize records in MARC 21 format rather than UNIMARC, and apply subject headings of the national library, or go together with LCSH. Third, Korean materials usually write Korean in Roman characters, but 5 libraries are marked with the original Korean language and available Hangeul search. Forth, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to 'history', 'economy', and 'politics' is largely shown in the highest rate. Fifth, Among the Korea-related subject heading, the terms such as 'Taekwondo', 'Kimchi', 'Dokdo', 'Donghae', 'Duman-gang', 'Baekdu-san' have different meanings in different libraries. However, these terms agree to LCSH in most libraries except for neighboring countries's libraries.

This research was conducted to analyze the actual condition of records related to Korea shown in the catalog of major 10 European university libraries. The results are as follows. To begin with, most libraries apply subject headings of the national library, or go together with LCSH, and organize records in MARC 21 format rather than UNIMARC. Second, Korean materials usually Romanize Korean words, but three libraries are only marked with the original Korean language and available Korean search. Third, Korea-related records in most university libraries are very poor except for some libraries and are generally 2 times less than Japan related records. There are even 6 times less in 2 libraries. Forth, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to 'history', 'politics', and 'economy' is largely shown in the highest rate.

An ocean buoy was deployed 10 km off Donghae city, Korea at a depth of 130 m to measure meteorological (air pressure, air temperature, wind speed, wind gust, wind direction, relative humidity) and oceanographic data (water properties and currents in the whole column) in real-time. The buoy recorded a maximum wind gust of 25 m/s (10 minutes' average speed of 20 m/s) and a minimum air pressure of 980 hPa when the eye of typhoon Maemi passed by near the Uljin city, Korea at 03:00 on 13 September 2003. The wave height reached maximum of 9 m with the significant wave height of 4 m at 04:00 (1 hour after the passage of Maemi). The currents measured near the surface reached up to about 100 cm/s at 13:00 (10 hours after the passage of Maemi). The mixed layer (high temperature and low salinity) thickness, which was accompanied by strong southward current, gradually increased from 20 m to 40 m during the 10 hours. A simple two layer model for the response to an impulsive alongshore wind over an uniformly sloping bottom developed by Csanady (1984) showed reasonable estimates of alongshore and offshore currents and interface displacement for the condition of typhoon Maemi at the buoy position (x=8.15 km) during the 10 hours.

The study of the scars formed on the bark of pine trees damaged by forest fire was carried out in the burned area of Samchuk and Donghae in 2000. Fire scars were formed on the bark of trees when fire passed by the tree. Fire scarring is usually found on the windward and leeward sides of the tree. Fire spread was analyzed topographically using the fire scars formed at the tree stem. Fire spread was closely related to the shape, slope and direction of the forestland. Four fire direction types are classified according to the shapes of the forestland. The height of the fire scar was higher on the leeward side than on the windward side of the trees studied. The burnt area of the total bark of the tree was over 30% in dead trees and below 12% in living trees. The regression model of the burnt stem area using the height of the fire scar, the diameter of breast height and the height of tree was Y=-2.484${\times}$Height＋0.04199${\times}$D.B.H-1.686${\times}$Windward＋11.172${\times}$Leeward＋23.432(r=0.936, F=409.968, P＞0.0001).

A landslide was occurred due to soil cutting for construction to expand the Donghae express highway in Dong-hae-City, Korea. The total area of the landslide was about $9,550m^2$ with 100 m of width and 87m of height. The landslide was occurred due to the internal factor of the unstable geological structure including the clay layer and the external factor of continuous heavy rainfalls. As the result of field instrumentation during the landslide, the horizontal displacement of the slope ground increases with increasing the accumulated rainfall by continuous rainfall during the rainy season. Also, the depth of sliding failure was decided by the horizontal displacement distribution during landslide occurrence. It makes sure that the horizontal displacement starts from the depth of sliding failure and the depth of sliding failure matches well with the location of the clay layer. As the slope stability analysis using Bishop's Simplified Method at the landslide area, the safety factor of slope during the rainy season was 0.53. This safety factor of slope was enough to trigger the landslide at this area. The depth of sliding failure obtained by analytical method matches well with the depth of the clay layer.

In case of the roads that pass the mountain area, the cut sections or the tunnels are constructed. And In winter season it appears sunshine few in the specific segment, the shade is continued last and the freezing sections occur. So, the attention is necessary in traffic safety. This study was to evaluate the influence of sunshine and surface freezing sections expected in route plans of roads using GIS and makes alternative ideas in road stability security. After selecting 29 km sections of Donghae highway and creating a 3 dimensional terrain surface through the digital conversion of design plan data, it reflects the road alignment data of the same coordinates and a 3 dimensional road modeling is created. It set shadow time of road surface for the solar trace in the winter solstice in 20 minute interval. Shade areas are displayed and inputed in polygon data by manual vertorizing. Graphic and attribute data of this shade section is constructed in geodatabase of ArcCatalog. And it extracted the freezing section using intersect fuction of the GIS spatial analysis. By analyzing the winter meteorological data of temperature, rainfall, snowfall, humidity, and etc. and grasping dangerous freezing section of the road surface effectively, it will be able to make alternative ideas of the preliminary stability evaluation reflected in basic design.

A marine air drone is a new device that can be used to respond to and prevent marine casualties. Determining the districts where marine air drones can be deployed helps the government decision makers identify efficient policy. The aim of this study is to develop a model using the fuzzy-analytic hierarchy process (F-AHP) and additive ratio assessment (ARAS) method to evaluate appropriate districts for deploying marine air drones. To verify the applicability of the proposed model, a case study was performed with respect to the Korea coast guard (KCG) districts. Since the deployed marine air drones are characterized by a high degree of overlap between the evaluation attributes. the F-AHP is used to determine the weights of identified criteria. The results of this study, show that missing people from the shore was the most important criterion for deployment of the drone. For ranking the local districts of the KCG, the ARAS is applied in the case study with the single goal of 50% reduction in marine casualties. Consequently, the highest priority district was identified as Mokpo, followed by Incheon, Seogwipo, Taean, Wando, Yeosu, Pohang, Tongyeong, Gunsan, Bolyeong, Jeju, Buan, Donghae, Sokcho, Ulsan, Uljin, Busan, Changwon, and Pyeongtaeg.

The hardness of kelp(Laminaria japonica) blade is a major deterrent to mass consumption in spite of its value as food. For improvement of kelp products as a special product of 'Donghae', the effect of additives on softening of kelp blade was studied. Kelp was composed of $34.74\%$ ash, $50.5\%$ carbohydrates, $4.81\%$ lipids and $9.98\%$ proteins on a dry weight basis. Glutamic and Aspartic acid are the principal free amino acids with percentage compositions of $2340mg\%\;and\;1650mg\%$ respectively of the $4719mg\%$ of total free amino acids. The softening effects of acetic acid and commercial mixed polyphosphate are more effective than that of monosodium carbonate. Boiling for more than 1hr was necessary for adequate softness of kelp blade in $0.3\%$ acetic acid solution. But, the kelp blade were softened more satisfactorily to 0.165kg/mm for only 30 min boiling in $0.2\%$ phosphate solution, and it is equal to boiling in $0.3\%$ acetic acid for 1hr.

This research was conducted to analyze the actual condition of subject heading related to Korean border shown in the subject headings of 7 countries: United States, France, Germany, Spain, Russia, China, and Japan. The results are as follows. To begin with, Korean border-related records in most other national libraries are in extremely poor conditions except for some countries like United States. Amnokgang and Dumangang-related records did not search at all in the France. Yellow Sea, Dumangang, and Baekdusan-related records did not search at all in the Spain. Second, even Dokdo we have effective control, the geographical name 'Korea' is not marked with catalog records except the United States and France. The Germany is displayed with the geographical name of 'Korea' and 'Japan'. Third, the East Sea(Donghae) already is marked with 'Sea of Japan' in most of the national library catalogs, and Yellow Sea(Huanghai) is marked with 'Yellow Sea'. Fourth, Amnokgang and Dumangang is marked with Chinese pronunciation in most in most of the national library. Fifth, Baekdusan is marked with Korean pronunciation in most countries. However the United States showed in 'Baekdu Mountain' and 'Changbai Mountain' discrimination. In the case of the Germany, 'Changbai Mountain' are marked with variant access point of 'Baekdusan'.

The purpose of this study is to examine the pattern and characteristics of population movement in Kangwon province. The data for this study were drawn from in- out- migration data established by Korea National Statistical Office(KNSO) between 2000 and 2007. Sample survey and depth interview were also used. The results showed that the population of all Si and Gun except Choonchun and Wonju declined. This decline of population in Kangwon province persisted during the last decades. The decline started with the industrialization in the 1960s and 1980s. The decline of population in Kangwon province continued in the 1990s and 2000s with the open agriculture policy rooted in UR and FTA. All Si and Gun can be classified into five groups in terms of population movement in Kangwon province between 2000 and 2007. The first group(Group B) is where in-migration from other Si and Gun and out-migration to Seoul and Kyunggi continues in the period. Choonchun, Wonju, and Sokcho belong to this category. The second group(Group C) is where out-migrarion to Seoul and Kyunggi is larger the in-migration. It includes Cholwon, Taebaek, Donghae, and Samchok. The third group(Group D) is where out-migration to Group B is larger than that of other places. Hwachun, Pyungchang, Hoegsung, Gosung, and Hongchun are included in this group. The fourth group(Group E) is where out-migration to both Group B and Seoul & Kyunggi is large. Youngwol, Gangnung, and Chungsun belong to this category. The fifth group(Group F) is where few population movement occurs. It includes Yangyang, Yanggu, and Injae. The findings also shows that the extent of population movement to Choonchun and Wonju is larger than that of Seoul and Kyunggi in recent period. This finding indicates that the effect of base city like Choonchun and Wonju has become in recent years.
