  • Fisheries and shipping industry as national basic industry need continuous growth and basic human resource development for international competition. This study was carried out through investigating of the related literature and reports. The purpose of study for developing direction and subject matter of curriculum in the fisheries marine science high school was as follows. Recently, reforms of vocational high school will expand professionalization and specialization. Therefore systematic curriculum of basic knowledge, basic skill and technical is required more and more in field work of fishery and merchant marine. The other important factors of curriculum improvement were cooperative role between school and local industry, adaptation of basic ability, job analysis, various curriculum opening. Above all, teachers of fisheries and merchant marine high school require advanced consciousness and must participate in revising curriculum. And the textbook of fisheries and merchant marine high school is useful to improve the level of learning ability degree and must be written by the related teacher, and the textbook contents must be studied by the expert group under professors leading to advanced discipline and skill of field work.

  • Recently, RFID technology play a key role to implement ubiquitous sensor network(USN). In this paper, we introduce trends of RFID technology, standardization, and then its applications. The purpose of this work is to suggest prosperous applications of RFID, which is applicable on marine information system, such as ship inventory management, management of container and its contents, sensing of environments within cargo hold, management of fishery boats. In case that RFID technology is utilized on marine information systems, it makes safety at sea and marine environments protection.

  • Flagellimonas eckloniae DOKDO $007^T$, isolated from the rhizosphere of the marine algae Ecklonia kurome collected from Dokdo Island, South Korea, is a marine Flavobacteria belonging to the family Flavobacteriaceae. The genome consists of 4,132,279 bp, 3,527 coding sequences with 37.85% G + C contents and two contigs in one scaffold chromosome. This strain contains a gene encoding proteorhodopsin, as well as other retinal biosynthesis genes, allowing it to utilize sunlight as an energy source. The strain contained only few segment of flagellar constructing gene cluster and this is not consistent with genus name Flagellimonas, therefore, revision of the genus name is required.

  • This survey was carried out to estimate the contents of heavy metals (Hg, Pb, Cd, and As) in 10 kinds of dried marine products (n=189) which are closely related to food resources. The contents of heavy metals were estimated by inductively coupled plasma spectrometer (ICP) and mercury analyzer. The values of heavy metals in dried marine products were as follows (Mean${\pm}$SD (range), mg/kg). The average contents of heavy metals in the dried marine products were Hg $0.058{\pm}0.069$ (0.002~0.502) mg/kg, Pb $0.178{\pm}0.598$ (ND~5.130) mg/kg, Cd $0.306{\pm}0.610$ (ND~6.802) mg/kg, As $5.282{\pm}6.158$ (ND~71.760) mg/kg. The range of heavy metal contents in dried marine products are low level, except of lead contents (n=2). In the comparison of heavy metal content by anchovy size, it was shown that cadmium, mercury and arsenic were meaningfully different. The contents of heavy metals by the shape of shrimp and Alaska Pollack were shown that the result of each group was meaningless. In the comparison imported production with domestic production, in the case of common squid, cadmium and arsenic were meaningfully different. The weekly average intakes of Hg, Pb and Cd from dried marine products takes about 1.17~11.52% of PTWI (Provisional Tolerable Weekly Intakes) that FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.

  • The residual contents of fluoroquinolones in fish and shrimp were analyzed by using HPLC-FLD and LC-MS. The limit of detection (LOD) and limit of quantification (LOQ) for fluoroquinolones by HPLC-FLD were 0.0030-0.0083 and 0.0090-0.0252 mg/kg, respectively. Those by LC-MS were 0.0019-0.0040 and 0.0059-0.0122 mg/kg, respectively. Recoveries regarding ofloxacin, norfloxacin, pefloxacin, ciprofloxacin and enrofloxacin ranged from 76.4-104.6%. The detection rate of fluoroquinolones was 7.5% from a total of 268 samples. In only one Korean bullhead sample, the sum of ciprofloxacin and enrofloxacin contents was detected at a higher level than its maximum residue limits (MRL) of 0.1 mg/kg. Ofloxacin, norfloxacin and pefloxacin were not detected in any samples and detection rates of ciprofloxacin and enrofloxacin were 3.4% and 6.7%, respectively. In detection rate by species eel (2.6%), loach (2.2%), Korean bullhead (1.5%), carp (0.7%) and snakehead (0.4%) were in order.

  • A sediment core drilled from Lake langer on King George Island was analyzed for a variety of textural md geochemical properties along with $^{14}C$ age dates. These data were combined with published records of other cores to provide a detailed history of Holocene variation of total organic carbon (TOC) contents with respect to terrestrial paleoclimate change. The lithologic contrast of the lower diamicton and upper fine-grained sediments shows the glacier activity and subsequent lake formation. Low TOC contents fluctuated during the diamicton deposition whereas the increase of TOC began with the lake formation during the postglacial period that started about 5,000 yr B.p More notable are the distinct TOC peaks that may imply enhanced primary productivity during the warm period. The uniform and low TOC contents may reflect the limited productivity during the evolution of the lake. However, the recent TOC readvance clearly indicates gradual warming on King George Island. However, the paleoclimatic signature in the terrestrial lake environment during the Holocene seems to be subtle and less distinct, compared to the marine environment.

  • This study was conducted the change of physico-chemical characteristics according to salt types; sun-dried salt, refined salt, Chinese sun-dried salt, salicornia herbacea salt and bamboo salt. As a results, volatile basic nitrogen(VBN) contents were 143.24-148.32 mg/100g, amino nitrogen(AN) contents were 1050.37-1096.91 mg/100g, total nitrogen(TN) contents were 1.62-1.78 %, moisture contents were 64.19-66.00 % and pH were 5.23-5.98. There are various type of salts that have difference in content of salinity, moisture, various mineral content, size and shape of salt crystal, granularity and chromaticity. In this study, Than the difference in the salt, difference in the fish sauce is determined to be insignificant, that is, there are no significant effect on the quality of the fish sauce according to the kind of salt.
