The purpose of this study was to identify food management behavior of housewives in island areas and to find if the behavior patterns were different between the regions, Hansan and Ullung island. An instalment based on previous researches was designed to measure food management behavior and was administered to 274 housewives in 1994 and 1998. Considering the condition of cooking-equipment possession, the percentage of possession for refrigerator, mix, electric range were significantly higher for households in Hansan Island than their counterparts. For food-budget planning, those in Ullung Island were more likly to plan their budget than those in Hansan Island. Menu planning patterns, considerable factors for food selection as well as cooking, and eating habits between meals were tuned out to be different between Hansan and Ullung areas. The findings of this study suggest that the condition of cooking-equipment possession, food-budget and menu planning, considerable factors for food selection and cooking, eating habits between meals were likely to vary depending on regions. Although housewives in two areas were living in island, they were not necessarily be uniform for all households but were diversified in food management behavior. Half of the respondents in Hansan Island and three-forth of the respondents in Ullung Island reported they had not planned their meal budget. The percentage of those who did not have their planned menu was 52.7∼54.1% in Hansan Island and 37.1∼38.5% in Ullung Island. When purchasing food material, housewives in Hansan Island consider the seasoning food as the most important factor, whereas those in Ullung Island consider family preference as the most important factor

The present study on the classification and description of the marine mesogastropods based on the materials which were collected during the period from 12th to 17th of July in 1989 at nine localities of the Ullug Island. Seven unrecored species in 6 families of mesogastropodes are new to the fauna of Ullung Island. As a result of this study, 7 families and 8 species of marind mesogastuopoes are riported from the Ullung Island. Two species of thim, Costalynia costulata(Dunker, 1860), Barleeia angustata(Pilsbry, 1901), are found to be new to the fauna of Korea.

This study was carried out to investigate the chemical composition of dustfall at Cheju(mean sea level; 71.7m, 33$^{\circ}$17'N, 126$^{\circ}$10'E) and Ullung island(mean sea level; 22.1m, 38$^{\circ}$29'N, 130$^{\circ}$54'E) from October 1993 to september 1994. The dustfall matter samples were collected by deposit gauges. The ionic components of each samples was analyzed by Ion Chromatograpy (Dionex 4000i), While heavy metals by Inductively Coupled Plasma Atomic Emission Spectrometry(ICP/AES; Shimadzu ICP-4). The results for seasonal variation of dustfall matter matter total amount, water-soluble ionic components and water-soluble ionic components total deposition amount to two sites were compared each other. The seasonal variations of dustfall amount at Ullung and Cheju island were found in order of Spring>Winter>Fall>Summer, and the maximum of dustfall amount were during the Yellow Sand period. Also, Total amount of water-soluble components except for $F^{[-10]}$ were high in Cheju more than Ullung island.more than Ullung island.

The present study on the classification and description of the marine archeogastropods based on the materials which were collected collected during the period from 12th to 17th of July in 1989 at nine localities of the Ullung Island. In addition to the 3fimilies and 8 species of the marine archeogastropods that have been reported, 7 familis and 29 species were reported including the 4 families and 21 unrecorede species from the Ullung Island as a result of this study. Among them, 3 species: Tugali decussata A. Adms 1852, Tuistichotuochus kima Shikawa & Habe 1965, Alcyna ocellata A. Adams, 1860 are found to be new to the fauna of Korea.

High concentration of chlorophyll a occurred around the Ulleung Warm Eddy off Ulleung Island in the East Sea of Korea in spring season. The abnormal distributions of chlorophyll a were captured by satellite remote sensing and measured field data. The temporal and spatial scale of the abnormal distributions were around 20days and 50km diameter off Ullung Island. The anomalies were quantified b)'estimated chlorophyll a derived from OCM and SeaWiFS ocean color data from 2000 to 2004. The origin of abnormal hish concentrations was estimated by this study. It was that suspended material discharged from the Nakdong River and the coastal water located in the southeastern part of Korean Peninsula moved to northeastern coast, and then moved to off Ullung island, The high chlorophyll a concentrations including inorganic materials were accumulated by anticyclonic eddy such as the Ullung Warm Eddy around Ullung island in the East Sea of Korea in spring season.

The seven hvpotrichs inhabiting the representative aquatic and terrestrial habitats of Ullung Island, Holosticho svlvotlca, Gonostom urn affine, Histriculus co uicola, H. muscomm, SDlonvchio mytilus, Aspidisca ciccadu and Euplotes m uscicolu are discovered for the first time from Ullung Island. Of these, two species of eonostomum affine (Stein, 1859) and fupfotes muscicofc Kahl, 1932 are newly recorded from Korea. The total seven species are listed and two newly recorded species from Korea are redescribed with illustrations.

The wind power equipment of Ullung island is composed of a hybride type of wind powers and diesel generators. The wind power generation in Ullung island is, howerever, not smooth due to the small capacity and weekness of existing power systems and line. Therefore, it is the purpose of this study to describe the technical problems and its solution through the investigation of actual conditions.

울릉도주목(Taxus cuspidata var. latifolia, 일명 회솔나무)의 각 부위에 함유되어 있는 taxol 및 관련 화합물의 함량을 조사한 결과 taxol 및 cephalomannine함량은 잎에서 높았고, 전구물질인 10-deacetyl baccatin III(10- DAB III), baccatin III의 함량은 수피에서 높았으며, 신초줄기와 종자에 서의 taxane 함량은 매우 낮았다. 또한 울릉도 전역에 자생 또는 재식되어 있는 주목의 taxol 및 전구 물질 10-DAB III의 함량변이를 조사한 결과, 5개 지역(나라분지, 태화령, 현포, 통구미, 도동)의 잎과 수피에서 이틀의 함량은 개체뿐 아니라 지역 사이에 큰 변이를 나타내였다. 분석개체 전체의 잎에서의 평균 taxol 함량( 건물 중 기준으로 0.017% )은 수 피의 것( 0.003 % )보다 월등히 높았으며, 전구물질 1 10-DAB III의 전체 평균함량은 수피(0.073%)가 잎(0.054% ) 보다 약간 높았다. 특히 섬 북서지역에 위 치한 현포지 역 주목 잎의 평균 taxol 함량은 약 0 0.024 %로 이는 보고된 태평양주목의 수피의 것보다 높은 것이며, 전구물질의 함량도 0.049%로 비교적 높았다. 이상의 결과로 지속적으로 채취가 가능한 울릉도주목 잎은 taxol 생산을 위한 중요한 자원이 될 수 있을 것으로 기대된다.

We studied the spatio-temporal characteristics of the Ullung Warm Lens (UWL) using the historical oceanographic data of the National Fisheries Research and Development Agency of Korea in the East Sea from 1967 to 1983. The UWL is basically a subsurface phenomenin found in 100 to 300m depths, and its existence is not well posed in the distribution of the sea surface temperature. The UWL has a typical size of 100 km diameter, and its center migrates within the region of 150 by 150 km south of the Ullung Island. The UWL is almost a permanent feature, and the probability of its occurence within our study area ($129\~132^{\circ}E,\;36\~38^{\circ}N)\;was\;86\%$.
