This study was carried out to investigate the dietary effects of chitosan mixture (CM), an herbal medicine mixture with Sukjihwang (HS), and CM containing HS (CHS) on obesity in an induced obese model of rats fed high-fat only (HF), in which supplemented diets of 5% CM (HCM), 5% HS (HHS), or 2.5% CM-2.5% HS (HCH) was tested for 6 weeks. Body weight gains, obesity indexes, and body fat contents in the experimental groups (HCM, HHS, HCH) were decreased compared with HF group. The levels of serum triglyceride, total lipid, total cholesterol and LDL-cholesterol in the experimental groups were markedly decreased, however HDL-cholesterol levels in the experimental groups were slightly increased compared with HF group. In addition, although serum ALT and AST activity, and relative organ weights were lower than those of HF group, serum albumin contents were not significantly different in all experimental groups including the normal control group (NC). In conclusion, there are improved effects on obesity in the obese model of animals with all experimental diets supplementations, and the improvement degrees on obesity depend on the content and compositions of the herbal medicine mixture. Further study is needed on the anti-obesity mechanism of these diets.

Korean clinochlore, kaolin, pyrophillite and a technical grade of alumina have been used to investigate the effects of Al2O3 on the formation and properties of cordierite bodies. The body compositions were formulated from the proper proportions of the above raw materials to cover the range of composition from the point corresponding to the stoichiometric formula of cordierite, bythe consecutive increasment of 0.2mol. Al2O3, toward the apex of Al2O3 on the MgO-Al2O3-SiO2 triaxial diagram. Each of bodies was fired with the elevated temperatures from 110$0^{\circ}C$ to 140$0^{\circ}C$ by 5$0^{\circ}C$ interval. Linear shrinkage and water absorption were taken as measures for the firing range of the bodies. The formation of cordierite was estimated from the comparative study of X-ray diffraction and dilatometry of the fired bodies. The formation of a large amount of cordierite was initiated about 120$0^{\circ}C$. The content of Al2O3 exceeded up to 0.8 mol. comparing to the stoichiometric formula of cordierite broadens the firing range of the body.

The variations of species compositions, standing crops and seasonal succession of phytoplanktons including Cyanophyceae, Chlorophyceae and Bacillariophyceae were investigated with physico-chemical elements of water to clarify the causes of water bloom according to the water depth in the Lake Unmun. The increased amounts of turbidity, T-N, T-P and SS originated from heavy rain and typhoon in the middle of June provoked to produce phytoplanktons. In July and August, the dominant species was Peridinium sp., while the subdominant species was Microcystis aeruginosa. In October, Aulacoseira distans was dominant and Asterionella formosa was subdominant. During the period of water shortage, the concentrated pollutants caused the decrease of precipitation, the long stagnation time of water body and the mixed pollutants by upwelling as decreasing water temperature could accelerate the water bloom. The preventives to decrease microalgal generation should be controled by the stagnation time of water body by increasing outflow to intercept water bloom such as ulacoseira sp. in October as well as summer.

In experiment 1, dietary self-selection of the 3 macronutrients, protein, fat, and carbohydrate were examined in male rats given 3 food cups of 80% carbohydrate, 80% protein, and 70% fat diets simultaneously. All the rats showed normal growth pattern and organ weight, which means they have ability to select just right kinds and amounts of nurients in order to support their growth and development. Mean values of caloric intake, body weight gain, serum lipid values and empty carcass compositions were not significantly differ between the upper and lower quartile groups of fat proportion of empty carcass compared to the lower quartile group(LF). Same feeding design was employed in experiment 2 where the effect of mild electric stress on food selection was studied. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The stress group showed higher caloric intake and body weight gain than control group, but no significant effects of stress on serum and empty carcass components was found. Even though normal rats seemed to select macronutrients according to their physiolosical needs, there were individual differences in food selection whether they were exposed to stress or not. Therefore life long individual food selection pattern may have a great influence on nutritional status and chronic degenerative diseases of eldery, and on aging process.

This study was conducted to investigate the utilization of Sargassum meal in the diet on juvenile ayu (Plecoglossus altivelis) reared in seawater. White fish meal and wheat flour were used as the dietary protein and carbohydrate sources in the control diet. Wheat flour in the control diet was replaced with $5\%$ and $10\%$ Sargassum meal. Three replicate groups of fish average weighing 4.0 g were fed one of three isonitrogenous$(45\%)$ and isocaloric (14.5 MJ /kg diet) diets for 7 weeks. Survival of all groups were above $80\%$. Weight gain, feed efficiency and protein efficiency ratio were not significantly affected by dietary Sargassum meal levels (P>0.05). There were no significant differences (P>0.05) in moisture, crude protein, crude lipid, crude ash and fatty acid compositions of whole-body fish among groups. It is concluded that Sargassum meal could be used as a dietary additive or alternative low-cost dietary ingredient up to $10\%$ for juvenile ayu reared in seawater.

Postlarval and juvenile anchovies Engraulis japonicus were collected using a gape net with wings in the coastal waters of Yeosu in July and August 2015, and their gut contents were analyzed. The size range of the postlarvae was 11.0-24.2 mm (notochord length) and that of the juveniles was 25.1-37.4 mm (standard length). Guts were empty in 64.5% of postlarvae and in 51.7% of juveniles. The dominant prey organisms in the guts of both postlarvae and juveniles were copepoda. Calanoida were important prey organisms for postlarvae and were dominated by nauplii of Paracalanus sp. and Calanus sp. as well as unidentified copepod naupill. Calanoida were also important in the diets of juveniles, whose gut contents were dominated by Paracalanus sp. and Cirripedia. Gut compositions were significantly different (P<0.05) among three body size levels in postlarvae and juveniles. As the body size of the postlarvae and juveniles increased, Calanoida constituted a larger proportion of the gut contents, while the proportion of copepod nauplii decreased.

One prominent characteristic of2,3,7,8-tetrachlorodibenzop-dioxin (TCDD) toxicity in rats is a reduction of body weight accompanied by an altered serum lipid profile such as hyperlipidemia. A single administration of TCDD (50 ug/kg) resulted in a decrease of body weight and increase of serum cholesterol in rats. TCDD-induced weight loss and serum cholesterol elevation was reduced in rats administered with water extract (100 mg/kg) or saponin fraction (40 mg/kg) of Panax ginseng C.A.Meyer. In contrast, the administration of Panax quinquefolium did not inhibit the TCDD-induced weight loss and serum cholesterol elevation. Histological examinations of liver and testis revealed the administration of saponin fraction of Panax ginseng attenuated the TCDD-induced hispathologicallesions whereas the administration of saponin fraction of Panax quinquefolium did not. High performance liquid chromatographic analysis demonstrated high percentiles of ginsenoside Rg and ginsenoside $Rh_1$ were evident in saponin fraction of Panax ginseng. Results indicate that the protective effects of Panax ginseng, not Panax quinquefolium, on the TCDD-induced toxicity might be resulted from different compositions of saponins in Panax ginseng.
