The relationship between the catches of tuna and hydrographic conditions in South-East Pacific region (latitude $5^{\circ}N-12^{\circ}S$, longitude $135^{\circ}W-115^{\circ}W$) was investigated by using the catch data of tuna and Digital Bathythermograph (DBT) data from December 9, 1980 to April 2, 1981. The results are as follows : The study area were located in South Eguatorial Current regions including equatorial upwelling regions in $5^{\circ}N\;to\;12^{\circ}S$. The horizontal mean temperature at the depth of 10m on the first quarter months in the study area was about $25^{\circ}C$C and the salinity of those fishing areas ranged from 34.8 to $35.0\%_{\circ}$. Yellowfin tuna and bigeye tuna were mainly caught in SW vertical temperature profile type, which the depth of thermocline ranged from loom to 300m, and temperature difference of thermocline was about $12^{\circ}C$. The deeper the depth of thermocline, the more the catches of tuna. While albacore tuna was caught well in SS vertical temperature profile type which the temperature of thermocline ranged from $9^{\circ}\;to\;26^{\circ}C$ and its gradient was very smooth. The depth of 1 ml/l surface of dissoved oxygen content ranged from loom to 200m in the South-East Pacific between longitude $140^{\circ}W-100^{\circ}W$, but it was shallower than 100 m near the North-South American continent. The catches of bigeye tuna were larger than those of yellowfin tuna in South Equatorial Current region. As approaching to the South and North American continent, the catches of yellowfin tuna and bigeye tuna decreased because the thermocline becomes shallower and steeper and the depth of the 1 m1/1 surface of dissolved oxygen content became shallower.

Atopic dermatitis (AD) is a form of allergic skin inflammatory characterized by late eczematous skin lesions. The incidence of AD is increasing, and it causes problems with administrative costs. Therefore, development of an AD treatment with no side effects is needed. The purpose of this study was to evaluate tuna heart ethanol extract (THEE), a functional extract from by-product of tuna. AD was induced by spreading 2,4-dinitrochlorobenzene (DNCB) on the backside of BALB/c mice. The effect of THEE was tested by measuring skin clinical severity score, secretion of cytokines and IgE, and proliferation. Secretion of $TNF-{\alpha}$, IL-4, IL-5, IL-13, and IgE significantly decreased in a THEE-independent manner. In contrast, levels of IL-10 and $IFN-{\gamma}$ significantly increased in mice sera and splenocytes. In addition, THEE alleviated AD symptoms compared to the DNCB only group. In conclusion, these results demonstrate that THEE has an inhibitory effect on AD and may be a useful substance for the development of cosmeceuticals.

This study investigated the effects of 27.12 MHz radio frequency (RF) heating on heat transfer phenomena during the thawing process of frozen food. To determine the velocity of the RF thawing machine, samples were frozen at $-80^{\circ}C$ and subjected to different power treatments. The phase change times (-5 to $0^{\circ}C$) of frozen radish were 30, 26, 13, and 8 min; those of pork sirloin were 38, 25, 11, and 5 min; those of rump were 23, 17, 11, and 6 min; those of chicken breast were 42, 29, 13, and 9 min; and those of tuna were 25, 23, 10, and 5 min at 50, 100, 200, and 400 W, respectively. The heating limit temperatures of the radish, pork sirloin, rump, chicken breast, and tuna samples were 19.5, 9.2, 21.8, 8.8, and $16.8^{\circ}C$ at 50 W; 23.5, 15.5, 27.3, 12.3, and $19^{\circ}C$ at 100 W; 42, 26.9, 45.7, 22.1, and $39.4^{\circ}C$ at 200 W; and 48.5, 54.7, 63.6, 57.3, and $44.9^{\circ}C$ at 400 W. These results suggest that high-power RF improves thawing velocity and heating limit temperatures, and that an improvement on the operation of the RF thawing machine, according to food temperatures, is needed.

Thig study was conducted to get a knowledge on chemical components of the cooked tuna bones (skipjack tuna bone and yellowfin tuna bone) as a food resource. The crude protein of tuna bone was around $29{\%}$ on the dry basis. The imino acid content (193 imino acid residues /1,000 amino acid residues) of collagen extracted from yellowfin tuna bone was higher than that (173 imino acid residues /1,000 amino acid residues) of collagen extracted from skipjack tuna bone, however, it was lower than that of collagen extracted from animal bone. The content and the ratio of unsatuated fatty acids in lipid extracted from yellowfin tuna bone were higher than those of lipid extracted from skipjack tuna bone, but they were lower than those of squid viscera oil. The contents of calcium and phosphorus as the major components of the tuna tone were 36.5 g and 17.2 g in 100 g ash in the skipjack, respectively, and 38.0 g and 18.7 g in 100 g ash in the yellowfin, respectively. It was concluded from these results that tuna bones could be effectively utilized as a mineral source.

Physicochemical, microbiological and sensory characteristics were determined during storage at 15, 25, and 35$^{\circ}C$ for six months to predict shelf-life of four fried rice retort dishes. Thiobarbituric acid (TBA) values were increased significantly and pH and acid values did not show any significant differences. Microbiological contamination levels were estimated as safe. Sensory evaluation were tested over 4 points during storage period. It maintained the commercial value during the shelf-life. TBA value as an effective quality indicator was used to estimate shelf-life with Arrhenius equation. The estimated shelf-life were 1,408 days (46 months) for beef fried rice, 1,353 days (44 months) for Ham fried rice, 1,164 (38 months) days for chicken curry fried rice and 1,182 (39 months) days for bacon tuna fried rice. In conclusion, shelf-life of all four fried rice dishes was predicted as longer than three years (36 months) at room temperature.

In the present study, in succession to the previous reports, the sterilizing values ($F_0$) of the thermal processes for the canned minced hen-clams in brine and the canned smoked baby-clams in oil were determined ana discussed. The heat penetration tests were carried out three times with three cans at a time for each canned product. The thermocouple was setted on the can so as the tip of the applicaotor fixed on the position a little below the geometrical center of the can. The test cans were placed in the middle layer of the crate in which the same canned products were loaded with, and test cans were arranged to the front, the middle and the rear in the retort. The heat penetration curve obtained for the canned minced hen-clams in brine showed a broken logarithmic heating curve, while that of the canned smoked baby-clams in oil showed a simple logarithmic heating curve. The calculated $F_0$ values for the canned minced hen-clams in brine were 47.79 for No. 2 can, 52.99 for Ne. 7 can. and 45.21 for No. 2 tuna can, respectively. And the $F_0$ value for th canned baby-clams in oil packed into No. 3B square can was 14.12. Additionally, the nomographs represent the relationship between $F_0$ vlaues and B values (process time including $42\%$ of come-up time) for the each canned product were constructed.

As a part of investigation for utilizing of canned tuna processing by-products as a food resource, we examined the processing conditions and characteristics (extraction methods and ashing condition) of a calcium powder from skipjack tuna bone. Among ashing, autoclaving, and shaking methods for extraction of calcium powder from skipjack tuna bone, ashing method was superior to other methods on the aspect of fish odor, white index, and calcium recovery of calcium powder. Based on the results of white index and soluble calcium ratio, the optimal ashing temperature and time for preparation of a calcium powder from skipjack tuna bone was at $900{\circ}C for 15 min$. Cohesive ratio of calcium powder by shaking at pH 7.0 was increased up to 16 hrs, but after that almost unchanged. Cohesive ratio of calcium powder by shaking for 24 hrs was increased at neutral and alkaline conditions (pH 6-8 and pH 9-11), but almost unchanged at acidic conditions (pH 2-5). For the effective utilization of the calcium powder from skipjack tuna bone, a suitable treatment is needed for improvement of calcium solubility at neutral condition.

Choline is important for normal membrane function, acetylcholine synthesis and methyl group metabolism. In this study, 185 food items customarily eaten by Koreans were selected from the data of the 2001 Korean National Health and Nutrition Survey and analyzed on the total choline content of the foods using enzymatic method of choline oxidase. Foods with high choline concentration (mg/100 g) were listed in sequence of quail egg (476.04 mg), dried squid (452.42 mg), beef liver (427.16 mg), pork liver (424.92 mg), tuna canned in oil (414.44 mg), boiled and dried anchovy (381.30 mg), dried Alaskan pollack (378.88 mg), chicken egg (309.88 mg), chicken liver (259.38 mg), soybean (238.62 mg), French bread with garlic (193.18 mg) and barley (183.73 mg). From this result, it is shown that dried fishes, prepared fishes, livers, eggs, pulses and cereals might be categorized as high choline food. Citron tea and green tea showed low choline content below 1 mg. Vegetables and fruits were also categorized into low choline food. No choline was detected in red pepper powder, beer, soju, soybean oil and corn oil out of foods analyzed in this study. Further study is required for analytic procedure of the foods of which results are inconsistent with USDA's data such as rice and wheat flour.

To utilize the oyster shell containing a lot of calcium, we investigated the bioavailability of calcium compounds from oyster shell. First, calcium oxide was prepared by burning of oyster shell at $1200^{\circ}C$. Its purity was approximately $98.5\%$. Calcium compounds, $CaCl_2$, and $CaHPO_4$, from the calcium oxide were prepared by chemical reaction. Effect on calcium absorption by the calcium compounds from oyster shell was improved using fish skin gelatin peptides.(FSGP), which was prepared by enzymatic hydrolysis of fish skin gelatin for 4hr with tuna pyloric caeca crude enzyme (TPCCE). in vitro experiment, calcium absorption by addition of FSGP in a mixture solution of calcium and phosphate was higher approximately $70\%$ than that by control. in vivo using calcium deficient rats, a group taken the diets with $3\%$ FSGP and $CaHPO_4$ was significantly improved amount of calcium and ash in femur and strength of femur. These results suggest that calcium compounds from oyster shell and FSGP could be used as an effective dietary calcium source.
