  • The large two-boat trawl is of importance in Korean fishery. It occupied 12.8% of total catches in 1974. The author analysed the reports of six large two-boat trawlers operated at the Yellow Sea and the East China Sea, in the term from September 1975 to March 1976. The results obtained are as follows; (1) 1,710 of total hauls are operated in the term, and the total catches amounted 559, 181kg. Then, 325kg of catch per unit effort (C. P. U. E) are obtained. The catches are specified into 28% of soles, 12% of shrimp, 8% of yellow corvenia, hair tail, kang-dari, and the rest of miscellanous fishes. (2) C. P. U. E. of the southern sectors of the Soheaksan Is. represented superior catches to compared with others sectors. (3) The monthly variation of C. P. U. E. between sea eel and yellow corvenia revealed positive correlation, whereas between sole and shlimp, between hair tail and rays revealed negative correlation respectively.

  • We explore each of the three major domestic fishery product markets in South Korea- Frozen Squid, Frozen Hair tail and Dried Anchovy- to assess whether we can find evidence for Law of One Price (LOP) across the five major cities- Seoul, Dae-Jeon, Dae-Gu, Gwang-Ju and Busan. To achieve our aim, we utilize two different types of unit root tests: Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt-Shin (KPSS) unit root test. In each of the three fishery product markets, we find evidence in support of LOP among several cities, which confirms that these markets are integrated to a certain extent. In particular, we find stronger evidence of LOP for Dried Anchovy market relative to the other two fishery product markets. Based on our findings, we argue that the Dried Anchovy market exhibits a greater degree of market integration across the five major cities in South Korea compared to the other two fishery product markets. The greater degree of market integration in the Dry Anchovy market is facilitated by its higher substitutability across cities; taken together these findings show that the market for Dried Anchovy in South Korea is more efficient than the markets for Frozen Squid and Frozen Hair tail.

  • This paper aims to study the browning reactions of lipid originated carbonyl compounds with nitrogenous compounds in dried fishes, flounder, mackerel, shrimp, hair tail fish, and whale. The major fatty acids in the flounder, the mackerel, the shrimp, and the hair tail fish were $C_{16:0},\;C_{18:1},\;C_{22:5},\;C_{22:6}$, and those in the whale meat were $C_{16:0},\;C_{18:1},\;C_{20:4}$. The nonpolar lipid contained higher percent of $C_{18:1}$ while the polar lipid contained higher percent of $C_{22:6}$. When those fishes were dried and stored, the PoV and CoV were high in the mackerel and the hair tail fish, whereas low in the flounder, the shrimp, and, the whale. The browning was developed more rapidly in the lipid soluble fraction than in the water soluble fraction of each sample, and the loss of available lysine and polyenoic acids were accompanied. The polyunsaturated fatty acids markedly decreased, particularly, in phospholipid than in neutral lipid, and $C_{20:5},\;C_{22:5},\;C_{22:6}$ were rapidly decreased during the storage.

  • This paper aims to study the reactions of lipid or oxidized lipid with protein during drying and storing hair tail fish(Trichurus lepturus) and flounder(Kanakius kitaharai) being generally consumed as dried seafood products in Korea and their influence on the drop of in vitro protein digestibility of these fish meat. The results of the study are as follows: The digestibility of the raw materials of flounder and hair tail fish was 87.63% and 86.08% respectively, and that of sundried and hot air dried materials went down $1{\sim}2$ percent with drying process. But in case of defatted and sundried materials, the rate increased 85.15% and 87.15% respectivley. After 30 days of storage, the digestibility decreased in all materials, and hot air dried meat showed a significant decrease. Trypsin indigestible substrate (TIS) contents of flounder and hair tail fish, in case of raw materials were 0.88 and 0.96mg/g. solid repectiveiy and in case of defatted and sundried materials, TIS contents showed a low increase and digestibility showed a high increase. Brown pigment formation had a wide range of increase in case of the sundried and hot air dried materials and it was increased with duration of storage and temperature. The major fatty acids in the fats of hair tail fish and flounder were $C_{18:1},\;C_{16:0},\;C_{22:6}\;and\;C_{16:1}$ and rate of unsaturated to saturated fatty acids was 79.2:20.8 for flounder, 67.8:32.2 for hair tail fish. After 30 days of storage at room temperature. saturated fatty acids increased compared with the raw materials while unsaturated fatty acids showed a tendency to decrease. Avaialble lysine of hair tail fish was higher than that of flounder and both of them lost about 8.23% of that in raw materials after 30 days of storage.

  • The objective of this study was to determine the breed differences in the 3'-untranslated region (UTR) of MC1R mRNA, which may be used to distinguish Korean brindle cattle (Chikso) from other breeds. We investigated the relationship between the variation of 3'-UTR of the MC1R mRNA and coat color among different breeds and the Korean brindle cattle with different coat colors. MC1R mRNA expression levels were determined in accordance with the coat color and hair colors of the tail. Total cellular RNA was extracted from the hair follicles of the tails in Hanwoo, Korean brindle cattle, Holstein and $Hanwoo{\times}Holstein$ crossbred cattle. After cDNA synthesis, PCR was performed. Sequences of the 3'-UTR of MC1R mRNA were analyzed. The 3'-UTR of the MC1R mRNA from different breeds of cattle did not show any variations. There were no variations in the 3'-UTR of the MC1R mRNA in Korean brindle cattle with different coat colors. The levels of MC1R mRNA expression in hair follicles of the tail varied substantially among the Korean brindle cattle with different coat colors, except yellow coat color. Correlation between the MC1R mRNA expression in the hair follicles of the tail and coat color may be present in the Korean brindle cattle, but not between the variations of 3'-UTR of MC1R mRNA and coat color. Further studies to determine the regulation of MC1R mRNA expression from the hair follicles of different coat colors will be beneficial in clarifying the role of MC1R in the coat colors of the Korean brindle cattle.

  • Rapunzel syndrome refers to a very rare condition in which swallowed hair forms a gastric trichobezoar that has a long tail extending into the small bowel. We describe a case of Rapunzel syndrome in an 8-year-old girl who presented with abdominal mass, epigastric pain and vomiting. Abdominal computed tomography scan showed a markedly dilated stomach filled with coarse heterogeneous materials. Upper gastrointestinal endoscopy revealed a huge hairy ball with a tail extending through the pylorus. We performed a surgical laparotomy and successfully removed a huge trichobezoar with a long tail extending into the middle portion of jejunum. Psychiatric consultation with review showed her past history of trichotillomania and trichophagia 4 years ago. But her parents denied further psychiatric therapy and she was lost to the follow-up. Rapunzel syndrome should be included in the differential diagnosis in children with chronic abdominal pain and trichophagia.

  • The Purpose of this study was to propose the most effective packaging method and storage conditions to apply to home-delivered meals for the elderly Changes in the physical and sensory qualities of pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok, in wrap packaging, top sealing and vacuum packaging were evaluated during storage at 25, 4 and -18$^{\circ}C$, for 5 days. The speed of falling-off in the foods qualities, under chilled and frozen storage conditions did not differ much as the 5 day storage period was too short for a proper assessment. The sensory characteristics of taste and texture were better evaluated in the chilled than in the frozen storage. The most effective packaging method at all the storage temperatures was the vacuum packaging, which assured the safety of the foods by the removal of oxygen. The lightness, springiness and hardness were significantly influenced by the storage temperature, period and packaging method, while the sensory characters were affected by storage temperature and the period. In conclusion, the quality of the vacuum packed pan fried oak mushroom and meat and soy sauce glazed hair tail, in frozen storage, were still fresh after the five days of the experiment. The shelf-life of those foods with wrap packaging, in chilled storage, were suggested to be three days. The quality of the roasted dodok, with vacuum packaging in chilled storage, was preserved for five days.
