음식물쓰레기의 발생량과 조성점유율이 증대됨에 따라 음식물쓰레기의 효율적인 처리 및 처분이 쓰레기 관리행정의 성공여부를 좌우하므로 도시규모별, 발생원별 음식물쓰레기의 양과 조성 그리고 단위 가정 및 퇴비화 의무대상업소에서의 배출현황을 조사하여 이를 통한 수거체제를 고찰하였다. 대전시와 충청남도 5개 표본도시로부터 조사한 음식물쓰레기의 연평균 조성은 50%를 넘고 있으며 주택가, 아파트, 상가지역간 조성비의 차이는 거의 없다. 종이류가 약 25% 정도를 유지하고 있기 때문에 매립장에 유입되는 일반폐기물의 75% 이상이 퇴비화로 처리가 가능하다. 음식물쓰레기 발생원단위는 단위가정조사의 경우 200~250g/인 일이며 매립장에서 전체 발생 쓰레기를 기준으로 조사할 경우 380~400g/인 일이다. 이는 가정의 구성원이 가정에서보다 가정 밖에서 2배에 가까운 음식물쓰레기를 배출하고 있음을 시사해 주고 있다. 음식물쓰레기 감량화 의무대상업소인 연구소와 관공서의 음식물쓰레기 원단위는 각각 166g/인 일과 215g/인 일로 조사되었고 대중음식점의 경우 수준에 따라 발생원단위는 현저하다. 고급인 경우 670g/인 일, 중급은 190g/인 일 그리고 대중음식점은 평균 60g/인 일이다. 1급 호텔의 경우 400g/인 일이며 집단급식소인 대학교 학생회관의 경우 170g/인 일로 조사되었다. 가정용 퇴비화 용기내에서 자연감량율은 1일 3~4%의 수준을 나타내고 있다.

The present study aims to evaluate protein and phosphorus availabilities of five different dietary protein sources during the 6-week feeding trial in juvenile olive flounder, Paralichthys olivaceus as determined by growth performance and phosphorus retention. Five diets containing blood meal (BM), poultry by-product (PBP), squid liver powder (SLP), feather meal (FM) and soybean meal (SM) were prepared by mixing a basal diet (BD) with one of five test ingredients at the ratio of 7 to 3. As a reference diet, BD contains three different protein sources such as white fish meal, casein and gelatin. After 2 weeks of the conditioning period, fish initially averaging 2.7$\pm$0.02g (mean$\pm$SD) were randomly distributed into each aquarium as a group of 30 fish reared in the recirculating system. Fish of triplicate groups were fed one of six experimental diets (BD+five test diet). After 6-week feeding trial, pro- tein efficency ratio (PER) of fish fed BM diet was the lowest in experiment groups. While fish fed PBP diet showed a significant higher PER as compared to the FM diet, and fish fed SLP diet and BD were a higher PER than did fish fed PBP diet. However, there was no significant difference in PER among fish fed SLP diet, BD and SM diet, and between SM diet and PBP diet. Phosphorus retention efficiency of bone (PR $E_{b}$) of fish fed BM diet was the lowest in all the diets, and fish fed FM diet showed a higher PE $R_{b}$ than fish fed BD and SM diet. However, there was no significant difference in PER among fish fed FM diet, SLP diet and PBP diet, and among SLP diet, PBP diet, SM diet and BD. These results indicate that SLP could be a suitable protein source for low pollution diets of olive flounder in the future fish feeds market. Furthermore, PBP and SM are available protein source to reduce P waste in the oliver flounder aquaculture with the use of proper mixture of other protein sources and more processing to improve protein availibility of these.ese.

We attempted to define the sources of sodium intake for the Korean population at prepared dish level to provide a basis for developing sustainable nutrition policies and feasible programs for sodium intake reduction. Dietary intake data from 2008 and 2009 Korea National Health and Nutrition Examination Survey was used in the analysis for sodium intake sources. Sodium intake from individual dish consumed by each subject was calculated and used in delineating major sodium sources at dish and dish group level for sub-populations of different sex and age. Also, sodium intake was compared between eaters and non-eaters of some specific dish groups with considerable contribution to total sodium intake. The number of subjects included in the analysis was 18,022 and mean sodium intake was 4,600 mg/capita/day. Major sources of sodium intake at dish group level were in the following order: kimchi (1125 mg, 24.5%), noodles (572 mg, 12.4%), soups (488 mg, 10.6%), stews (399 mg, 8.7%), and cooked rice (284 mg, 6.2%). The magnitude of contribution to total sodium intake by soups and stews was different by age group. Sodium intake difference between eaters and non-eaters was much larger for kimchi group (2,343 mg for male, 1,452 mg for female) than for soups or stews. Interaction between consumption of aforementioned specific dish groups and age was highly significant (p < 0.0005) for both sexes. This study revealed an importance of having not only the control over sodium content of foods/dishes, but also the customized approach for different groups of population to accomplish an appreciable reduction in sodium intake.

This study was designed to investigate the effect of different sources of $\omega$3 fatty acid in the diet with a similar polyunsaturated/saturated (P/S) fatty acid ratio and $\omega$6/$\omega$3 fatty acid ratio as well as excess DHA on the plasma fatty acid composition and cholesterol level of rats. Three experimental diets contained 10% (w/w) dietary lipids. The control diet and one treatment diet were corn oil-based diets with different $\omega$-3 fatty acid sources: perilla (CO) or fish oil (CF), respectively. In order to examine the effect of excess DHA, the other treatment diet (FO) was a fish oil-based diet with corn oil to supply essential fatty acids at the level of 1.8% (w/w) of the diet. Female Sprague Dawley rats were fed the experimental diets for 2 weeks prior to mating and throughout gestation and lactation. Pups were weaned to the same diet of dams at 21 days of age. Plasma fatty acid compositions and cholesterol contents were analyzed for pups at 3th, 7th and 10th week after birth. Plasma DHA concentrations increased significantly as the level of fish oil supplementation increased. Three-, seven- and ten-week old rats fed on CO diet which contained only $\alpha$-lino1enic acid as a $\omega$-3 fatty acid Source had Plasma DHA levels of 4.85%, 3.15% ana 2.47%, respectively, suggesting that rats at this period of development can convert $\alpha$-linolenic acid to DHA. But the ability to form DHA might be limited, since dietary DHA showed to be more effective in raising the plasma level of DHA. There was a significant negative correlation between DHA and cholesterol concentration of the rat plasma at 7th week (r=0.34, p<0.05) and l0th week after birth (r=036, p<0.05), proving the hypocholesterolemic effect of DHA.

This experiment was conducted to evaluate the bioavailability of different organic selenium (Se) products in finishing pigs. A total of 48 growing pigs, average body weight $47.6kg{\pm}0.05$, were allotted to four different treatments in a randomized complete block (RCB) design in three replicates with four pigs per pen. Three different organic Se products, Se-enriched yeast (treatments A and B) and Se-proteinate (treatment C), were used in conjunction with a basal diet with no added Se as a control treatment. In growing period, pigs were fed the same diet but finishing pigs were fed each treatment diet containing organic Se products for 6 weeks. During the experimental period, feed intake and body weight were measured and blood samples were collected to determine the Se concentration. At the end of this experiment, 3 pigs per treatment were killed and various tissues (loin, liver, kidney, pancreas and spleen) were collected to analyze the Se concentration. The body weight, and average daily feed intake (ADFI) were similar among treatments, but the average daily gain (ADG) was increased on Se-proteinate treatment (p<0.01) and gain-to-feed ratio (G/F ratio) was improved on Se yeast B or Se-proteinate treatment (p<0.01). The tissue Se content was also increased when pigs were fed organic Se sources, and Se was retained efficiently in loin (p<0.01) and kidney (p<0.05) when Se yeast B was provided. The serum Se concentration was increased when organic Se was provided and was higher when pigs were fed Se-proteinate (p<0.01); subsequently liver Se was also higher on Se-proteinate treatment than other treatments. The Se yeast A treatment did not show any increment of Se concentration both in serum and tissues. This result demonstrated that Se retention and bioavailability in finishing pigs were varied by Se products although organic sources were provided. Consequently, each organic Se product should be evaluated before it is used as a supplement in animal feed.
