  • Based on the plankton samples collected in the Korea Strait in 1972, a study was conducted on the vertical distribution of chaetognaths in relation to water masses in th Strait. The settling volume of total plankton collected in the Strait ranged from 0.3 to 5 cc/10㎥ and showed a distinctive variation in the vertical distribution between day and night. The large amount of volume was found in the upper layer at night and deeper layer during the day time collections. A total of 19 species and one forma of chaetognaths were identified from the present samples. In general, the number of species and individuals of chaetognaths were abundant in the upper layer. But in August they were distributed almost evenly from the surface to the bottom layer. Particularly several species of warm water chaetognaths, i. e., Sagitta enflata and S. regularis appeared abundantly in the deeper layer in summer. This indicates a sinking phenomenon of warm water from the surface to the bottom layer. As for the vertical distribution of S.elegans, a cold water species, in the Korean Strait, it is restricted only to the bottom layer except in the region of upwelling where they appear in the middle layer. This species is usually distributed in the depth of below 150m in the southern part of Japan Sea(Park, 1970), and it is usually distributed as far south as the Strait between Busan and Tsushima. In addtion, cold water species of copepods such as Pseudocalanus minutus and Metridialucens appear in the western side of Thushima. As indicated by the vertical and horizontal distribution of S. elegans in the Strait, the cold water flows as an undercurrent along the bottom from the southern part of the Japan Sea to the Korea Strait between Busan and Thushima in summer and fall, with a trend of uprising along the coast of Korea. S. decipiens has been found only in the depth of below 50m except in the coastal area where they appear in the upper layer. Therefore the vertical distribution of this species can be used for tracing the occurrence of upwelling and the movement of water from the middle layer.

  • 1991년도 입사, 축산물품질평가원 공채1기로 현재 대구경북지원 평가부장으로 재임하고 있는 이동원 평가부장을 만나 27년째 축평원 근무에 대한 그의 이야기를 들어보았다. 9월초 취재를 위해 대구에 도착했을 때는 초가을에 접어들어서인지 하늘에는 수채화로 그림을 그린 것처럼 구름이 뭉실뭉실 맑고 화창한 날씨였다. 9월은 낮과 밤이 선선할만한데 대구는 아직도 막바지 더위가 기승을 부리고 있었다. 그와 대구경북지원에 대한 이야기를 나누다보니 그에게서 지원의 무한한 애정과 열정을 느낄 수 있었다.

  • 열대야는 하루 최저 기온이 25도를 넘는 것으로 낮에 달구어진 지표면의 열기가 대기 중으로 빠져나가지 못해 일어난다. 열대야에서는 인체의 중추신경계가 흥분해 잠을 자지 못하거나 자주 깨며 이 때문에 다음날에 졸리고 피로한 '수면지연증후군'이 나타나기 쉽다. 무더운 여름 밤, 열대야 속에서 쾌적하게 잠자고 건강을 유지하는 특별한 방법에 대해 소개하고자 한다.

  • 야경사진은 자연광 일색인 일상의 낮과는 달리 인공광과 자연광이 함께 어우러져 있는 밤의 풍경을 표현한다. 특히, 야경사진은 빛을 어떻게 효과적으로 이용할 것인가라는 문제에서 한 발 더 나아가 얼마만큼의 빛을 받아들일 것인가를 고민하게 하는 촬영이다. 바로 이 문제는 노출시간으로 연결되며 조리개 값을 실정하게 한다. 더불어 작가의 낭만적인 미적 감각을 함께 표현할 수 있는 촬영방법이다.

  • The chestnut management standard diagnostic table is developed and would be utilized in order that a manager raising chestnuts checks where the own level of management is and grasps current state of own for the purpose of planning aims and advancing toward a higher level. The developed 'Chestnut management standard diagnostic table' consisted of 3 first classified items, 19 second classified items and 2 product indicator items by the chestnut experts consultative meeting. A survey of 212 farmhouses in 4 major producing area was conducted. Except invalid survey of 53 farmers, 159 farmhouses interviewed were used in analysis. Total score was calculated with sum of each item's score. According to the survey results, average score is 68.0 and Buyeo received the highest score of 69.7 and Suncheon received the lowest score of 61.8 by regional groups. The higher the group in score, the better it is in output per hectare. But the property of 'the ratio of the best products in total products' does not show a statistical correlation. Generally the score of 'management-based evaluation indicator part' and 'management and sale capacity indicator part' in Suncheon was low because of many elderly people. In part of 'manufacturing technology indicator' as Environmentally-Friendly production is progressed in over 70% of four regions, when comes to a disease and insect pest control there are rarely farmhouses having a way of crop dusting.

  • In this study, the spatiotemporal surface temperature changes were analyzed in the Korean peninsula. The surface temperature variation was estimated using the split window method and NOAA/AVHRR data in 1991, 1995 and 2000. The ranges of differences in temperature between day time and night time were $3-15^{\circ}C$ around the peninsula. The differences in seasonal variations and yearly fluctuations in big cities were lower than those in rural areas and showed clearly the effects of the urbanization. The characteristics of urban heat affects were further determined based on the day and night time temperature comparison on Busan metropolitan area between these periods. Finally, the future use of this technology was suggested for the urban environmental planning.

  • Species composition and seasonal variations of fishes collected by winged stow net on anchors in the coastal water off Namhae Island was studied from May 1989 m April 1990. During the study period, a total of 56 fish species were collected. Engraulis japonicus, Conger myriaster, Trichiurus lepturus, Sardinella zunasi, Ammodytes personatus, and Thryssa kammalensis predominated. These six species accounted for 93.9% of the total number and 81.3% of the total biomass of fishes collected. Fishes collected by winged stow nets on anchors were primarily small fish species or early juveniles of large fish species. Both abundance and species composition of fishes changed with season. Seasonal peaks of number of species occurred in spring and fall, while those of number of individuals and biomass occurred in spring. The lowest number of individuals and biomass were observed in winter. Low species diversity indices were observed in summer. These low diversity indices in summer were mainly due to predominance of E. japonicus which accounted for approximately 90% of all fishes collected. More species and greater biomass were collected during nighttime.
