In this study, clothing consumption behaviors of Russian and Korean female college students were compared. Data were collected by conducting surveys in Russia and Korea. In results, Russian female college students spent considerably more money on clothing than did Korean students, compared to the income level. Korean consumers bought clothing mostly in the department stores, whereas Russian consumers preferred large shopping centers, discount stores and traditional markets to shop clothing. As important factors affecting clothing purchase decision, Russian consumers considered country of origin while Korean consumers considered style. Korean consumers were satisfied more on domestic brands than did Russian consumers while Russians were more satisfied with foreign brands than did Koreans. Russian consumers considered diverse factors in forming attitude and buying intention toward domestic and foreign brands. In contrast, Korean consumers' attitude and purchase intention were influenced much by style. Based on study results, marketing implications were provided.

This study aims to investigate national image of South Korea held by russians. Surveys(based on Free-association Image) and discussion were conducted on LiveJournal (internet blog) with russian netizen. A national image is influenced by a subjective perspective rather than an objective one. Therefore, an image can differ substantially from reality. Futhermore, it takes a long time to change an established image, particularly to a positive image. According to the results, the image of South Korea were dominated by unstable political situations, especially factors related to North Korea. In addition, based on Free-association image, thinking about Korea or Korean, most russians recognize Korea(South) with North Korea. Above all Russians recognize Korea, basing their images on factor of the past or their neighbors-russian korean- or famous Korean brand like Samsung, LG, Hyndai, "Dosirak". Russian netizen did not recognize South Korea as one of leading countries in Asia, paying little attention to South Korea compared to China or Japan. We belive that it is necessary to consider these situations in future efforts to enhance the national image of South Korea.

From a result of surveys on the biodiversity monitoring for moths in Korea, six species of micro-moths that were never known from Korea are reported here for the first time from this country. They are: Udea pseudocrocealis(South, 1901) of the family Crambidae, which has been known as endemic to Japan; Epinotia albiguttata (Oku, 1974) of the family Tortricidae, which was known belonging to Hikagehamakia Oku, 1974; and four species of the family Gelechiidae: Protoparachronistis concolor Omelko, 1986 and P. discedens Omelko, 1986, which were described from Primorisk, Russian Far East; Thiotricha pancratiastis Meyrick, 1921, which is known from Isl. Jejudo, and Thiotricha sp. which is being described in a separate paper. Here we provide images of adults and genitalia for the unrecorded species with a brief diagnosis.

Ships and industries damage the delicate coastal ecosystem in many parts of the world by releasing oil or pollutants into rivers, coastal and offshore waters. After a tanker accident the biggest problem is to get a clear idea of the extent of the oil slick and predict the way it will move. For natural and man-made oil spills it is necessary to operate a regular and operational monitoring. In the Mediterranean, North and Baltic seas aircrafts or ships normally carry it out. This is expensive and is constrained by the limited availability of these resources, borders between countries, daylight hours, good weather conditions, etc. Satellite imagery can help greatly identifying probable spills over large areas and then guiding aerial surveys for precise observation of specific locations. The Synthetic Aperture Radar (SAR) instrument, which can collect data almost independently of weather and light conditions, is an excellent tool to monitor and detect oil on water surfaces. SAR is currently on board the ENVISAT, ERS-2 and RADARSAT satellites. The application of this technology to the investigation of oil pollution in the Caspian, Black, Mediterranean, North and Baltic seas is shown.

1883 년에 진수된 러시아 순양함 드미트리 돈스코이(Dmitri Donskoi ; 6,200톤)호는 러일전쟁에 참전하여 1905년 5 월 29 일 동해 울릉도 근해에서 침몰되었다고 알려져 있다. 이 침몰선을 찾기 위해 1999 년부터 2003 년까지 5 년간 탐사를 수행하였다. 러시아와 일본의 해전사 자료를 토대로 침몰 예상 위치를 파악하여 탐사해역을 설정하였다. 3 차원 해저 지형 조사, 해상 자력 탐사, 천부지층조사, 해저면 영상 조사 등의 기록을 종합 분석하여 침몰선으로 추정되는 이상체를 확인하였다. 지구물리탐사를 통해 확인된 이상체에 대해 심해카메라와 무인잠수정(remotely operated vehicle) 및 유인잠수정 Pathfinder 를 이용한 정밀조사를 수행함으로써 울릉도 저동항에서 약 2 km 떨어진 해역, 수심 400 m 지점의 심해 계곡 중턱에 걸쳐진 돈스코이호를 발견하였다. 침몰선체에는 152 mm 함포 등이 그대로 장착되어 있고 선체 주변에는 전쟁 시 불에 탄 조타기 등의 잔해가 놓여있었다. 조사 지역은 강자성을 띤 대규모 화산암 지대이기 때문에 자력탐사로 침몰선을 식별하기가 어렵다. 천부지층탐사와 해저면 영상조사는 심해 계곡의 심한 지형 변화에 따라 음파의 난반사가 일어났으며 자력탐사 역시 자력이상도의 왜곡으로 인하여 이상체 식별이 곤란하였다. 그러나 중천해용 다중빔 음향 측심기의 경우 탐사선을 최대한 저속으로 운항하고 수심 및 지형에 따라 빔 각도를 조절하여 획득한 해저영상은 침몰선 확인에 매우 유용하였다.

To manage national territory and cadastral data efficiently, accuracy and cost-efficiency in cadastral boundary surveying is inevitable. The efficient management of cadastral data is a very important element in national land management. Survey techniques are being introduced. Recently, improvements in survey techniques have been made with the development of satellite surveying, Allowing accurate and fast surveys. If we can calculate the output accurately in real-time in survey fields, it will open a new method in cadastral detail surveying. According to the classification on Law of cadastral surveying, Cadastral surveying can be divided into cadastral control point surveying and cadastral detail surveying. The control point survey can be divided into cadastral triangulation surveying and cadastral traverse surveying. The detailed survey is usually perform by plane surveying. Among these, cadastral detail surveying will be reviewed in this study. In this study, the combination of the satellites, such as US managed GPS and Russian managed GLONASS was used. In the satellite survey in downtown, data interruption symptoms arose(according to the mask angle of the satellite). Therefore; we combined the satellites to get date more accurately. A block of Haewoondae New City in Busan, Korea, which has Numerical Cadastral Law was selected as the sample area for this study. Block II and III are surrounded by high rise apartments. One side of Block I and IV is level ground and the other side is full of high rise apartments. Especially, Block II is surrounded by high rise apartment houses with 20 meters width. In the results of the study Block II did not satisfy the allowable precision, while Block I, II and IV satisfied the allowable precision of the enforcement regulations of Cadastral Law. Therefore, it is judged that the traditionally used Total Station method should be used for supplementary survey on Block II, in stead.

In the last ten years, marine geological and geophysical survey and research were conducted by Japanese, Russian and American scientists in the East Sea of Korea (Japan Sea). Many research results were published. However, regional research of the geology of the continental margin of the Korean Peninsula was not conducted. This study has made on attempt to classify submarine strata and stratigraphic boundaries. The study has revealed characters of submarine geology and structure. Isopach maps of each identified stratigraphic unit have been constructed as the results of this study. The study was conducted on the basis of analyses of marine seismic surveys carried out in the continental margin of the East Sea between Kangneung and Pohang. Three depositional basins were identified in the study area and they were named as, Mukho Basin, Hupo Basin and Pohang Basin. The Mukho Basin is developed in continental slope and shelf in the area between Kangneung and Samcheog. Quaternary and Pliocene sediments attain a maximum thickness of 900 m. Basement rocks are interpreted as granite and gneiss. They are correlated with granite-gneiss of the Taebaecksan Series of Pre-cambrian age and the Daebo granite of Jurassic age. The Hupo Basin is developed in the continental shelf between Uljin and Youngdeok. Quaternary and Pliocene sediments attain a maximum thickness of 600 m. Basement rocks were interpreted as granite and gneiss and they are correlated with metamorphic rocks of Pre-cambrian age and the Daebo granites, comprising the Ryongnam Massif. The Pohang Basin is developed in the area between Pohang and Gangu. This basin contains Miocene and older sediments. Basement rocks are not shown. Many faults are developed within the continental shelf and slope. These faults strike parallel with the coast line. A north-south direction is predominant in the southern study area. However, in the northern study area the faults strike north, and north-west. The faults are parallel to each other and are step faults down-thrown to the east or west, forming horst and graben structures which develop into sedimentary basins. Such faults caused the development of submarine banks along the boundary between the continental shelf and slope. This bank has acted as a barrier for deposition in the Hupo Basin. Paleozoic sedimentary rocks distributed widely in the adjacent land area are absent in the Mukho Basin. This suggests that the area of the basin was situated above the sea level until the Pliocene time. The study area contains Pliocene sediments in general. These sediments overlie the basement complex composed of metamorphic rocks, granites, Cretaceous (Kyongsang System) sedimentary rocks and Miocene sedimentary rocks. These facts lead to a conclusion that the continental shelf and slope of the study area were developed as a result of displacements along faults oriented parallel to the present coast line in the post Miocene time.
