The purpose of this study was to optimum formulation conditions for the preparation of retort pouched marsh snail Senisulcospira livertina soup with curled mallow Malva verticillata and optimized the sterilization process. Samples were prepared according to the central composite rotatable design (CCRD) by encrypting the amounts of marsh snail broth, boiled marsh snail and blanched curled mallow, which are the main ingredients of retort pouched marsh snail soup with curled mallow. Raw marsh snail was sorted by size of 4-5 level, and then marsh snail was washed and removed sediment in a water tank for 3 min, then boiled at 100℃ for 10 min, and then directly separated by hand to prepared a boiled marsh snail. The marsh snail cube is prepared by combining blanched at 100℃ for 10 sec curled mallow (27 g) and green onion (20 g) with boiled marsh snail (27 g) and soybean paste (10 g). The marsh snail cube was placed with marsh snail broth (416 g) in a retort pouch film. Subsequently, sterilization (118.0℃, 25 min; F₀ value, 12 min) and cooling were performed using a steam retort.

청주시민 1,390명에게 기존에 향토 음식으로 조사되었던 89개 음식에 대하여 청주시의 향토 음식으로 적합한 것을 10개씩 선택하라고 설문조사를 하여 연령별, 성별, 직업별로 분석하였다. 성별 성별 결과에서 남자는 1위 올갱이국(282), 2위는 도토리묵밥(174), 3위는 콩국수(164), 4위는 삼겹살과 해장국(158)을 나타냈고, 여자는 1위 올갱이국(520), 2위는 도토리묵밥 {322), 3위는 콩국수(272), 4위는 삼겹살(271), 5위는 해장국(262)이 차지하였다. 남녀를 합한 결과는 1위는 올갱이국(802명), 2위는 도토리묵밥(496명), 3위는 콩국수(436), 4위는 삼겹살(429명), 5위는 해장국(420명), 6위는 산채 비빔밥(323명), 7위는 보신탕(322명), 8위는 닭도리탕(321)이 차지하였다. 성별 직업별 결과에서 주부는 삼겹살을 적게 택하였고, 회사원은 산채 비빔밥을 적게 택한 대신 다른 직업에서 적게 택한 보신탕과 닭도리 탕을 많이 택하였다. 그러나 이들 중 콩국수와 산채 비빔밥, 보신탕은 여름에만 먹거나 여름에만 재료가 나므로 향토 음식으로 보기에는 무리가 있다.

Members of this family Sciomyzidae are known as marsh flies and snail-killing flies because most of the known larvae are obligate predators of Mollusca, especially freshwater and terrestrial Gastropoda. Most species are found in the shallow ephemeral aquatic habitats with rich organic substrates, such as the hard-water streams, small ponds and lakes in mountain valleys. To date, a total of 8 marsh fly species in 4 genera have been known in Korea. During a taxonomic survey of the family Sciomyzidae in Korea, the authors have found the genus Ditaeniella Sack, 1939; thus, it was discovered for the first time in Korea. This genus can be distinguished by the other related taxa with hairs over much of the mesopleuri, hairs on the prosternum and one orbital seta. In addition, the nominate species, Ditaeniella grisescens Meigen, 1830 was also firstly recoded in the Korean fauna.

The purpose of this study was to search the calcium and iron rich foods in Korean people. The food sources presented in the current home economics textbooks of middle and high school were investigated. And 40 kinds of calcium and iron rich foods were selected by the quantity in 100g edible portion. one serving size and according to 1997 food supply data. Also 3 major food groups of calcium and iron supply in Korean were identified, and 10 rich foods for each food groups were selected. The results were summarized as follows. 1. The food sources of calcium 1) The food sources of calcium presented in the home economics textbooks of middle and high school are milk and dairy products. small fishes such as anchovy icefish and dried strip and green vegetables etc. 2) The calcium rich foods by 100g edible portion were in order of skim milk powder river snail sesame sea mustard. whole milk powder. snapping turtle loach sea tangle(dried) opossum shrimp and sea lettuce(dried). And the calcium rich foods by the calcium content in one serving were in order of river snail snapping turtle opossum shrimp loach spiny lobster skate skim milk powder small alaska pollack freshwater crab condensed milk whole milk powder skate ray and milk. 3) The 3 major calcium supply food groups in Korean were vegetables fish and shellfishes and milk and dairy products. 4) The calcium supply foods according to the quantity of food supply in 1997 was in order of sea mustard, milk anchovy chinese cabbage soybean skin milk powder laver shrimp welsh onion and maize. The vegetables were the important sources of calcium in Korean. 2. The food sources of iron 1) The food sources of iron which are commonly presented in the textbooks of middle and high school were meat liver egg(egg yolk) and green vegetables etc 2) The iron rich foods on the basis of the iron content in 100g edible portion were in order of surf clam marsh clam laver(dried)( sea lettuce(dried), crayfish pelilla seed little neck clam orient hard clam, venus clam, and freshwater carab. And the iron rich foods by the iron content in one serving were in order of surf clam marsh clam crayfish little neck clam orient hard clam freshwater crab venus clam hen cockle green confertii(fresh) pen shell and spiny lobster. 3) The 3 major iron supply food groups in Korean were cereals an cereal products fishes and shellfishes and vegetables. 4) The iron supply food according to the quantity of food supply in 1997 was in order of soybean sea mustard maize rice meat edible viscera laver wheat flour, pook, red pepper, egg and bovine meat.

This research was conducted to investigate pollutant load unit factor from aquacultural farms. Pollutant load unit factors were investigated on the 13 kinds of fish type, i.e., Trout, Leather Carp, Eel, Carp, Cartfish, Freshwater Eel, Crucian Carp, Colored Carp, Sturgeon, Marsh Snail, Sweetfish, Pond Snail, Eriocheir Sinensis. Water qualities in aquacultural farms were investigated wide range of values by fish type and pollutant items. High BOD and COD values were observed at the Leather Carp (Ponded water system), Cartfish (Ponded water system) and Freshwater Eel (Recirculating System). TOC and DOC values were relatively high at the Freshwater Eel (Recirculating System) and Eriocheir Sinensis (Extensive). Eel (Ponded water system) and Freshwater Eel (Recirculating System) produced high concentrated nutrient pollutants, i.e., T-N, T-P. Pollutant load unit factors are dependent on fish type, aquacultural type, water quality items, etc. If some fishes have similar basic unit values, those could be applied for TMDLs as a group of fish having same pollutant load unit. The water quality concentrations of post treatment facilities' (mainly reservoir tank) effluent were higher than those of fish raising bath because of extracting pollutant from sediment in the reservoir tank. Therefore, it needs to the management and regulations about post treatment facilities.

Recently, we reported (J Korean Soc Food Sci Nutr, 31(3): 516-520, 2002) that Semisulcospira libertina (Marsh Snail) pretreatment has a hepatoprotective effect on $CCl_4$-induced liver damage in rats. The purpose of this study was to investigate the possible mechanisms of hepatoprotection by S. libertina (SL) on liver injury induced by acetaminophen (AA). Male ICR mice were pretreated with dehydrated powder of SL once daily for three consecutive days, given a single toxic dose of AA (450 mg/kg) and liver function determined 24 h later. Liver damage was assessed by quantifying serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and sorbitol dehydrogenase (SDH) activities, and by measuring hepatic lipid peroxidation. To confirm possible mechanism(s), the content of hepatic glutathione (GSH) and gene expression of tumor necrosis factor a (TNF $\alpha$) mRNA by reverse transcription-polymerase chain reaction (RTPCR) were also measured. Pretreatment with SL dramatically lowered AA-elevated ALT, AST and SDH activities. SL pretreatment decreased AA-produced lipid peroxidation by 11% and restored the AA-depleted hepatic GSH by 27%. Furthermore, SL markedly suppressed the expression of TNF $\alpha$ mRNA induced by AA. Our findings revealed that the possible hepatoprotective mechanisms of SL could be attributed, at least in part, to the glutathione-mediated detoxification as well as the regulation of TNF $\alpha$ mRNA expression.

본 연구는 단양군이 개발한 3개의 고구려 음식과 19개의 향토음식에 대한 인지도와 선호도를 분석하여 향토음식 활성화의 기초자료로 제시하고자 한다. 설문지는 거주민과 관광객에게 각 150부씩 배포하고 261부를 회수하였고, 232부를 이용한 분석결과는 다음과 같다. 첫째, 22개의 향토음식에서 '올갱이 해장국', '도토리 묵밥', '소백산 산채 비빔밥', '더덕마늘구이'가 인지도와 선호도에서 높게 나타났다. 둘째, 인지도 분석에서 남성은 '올갱이 해장국'과 '남한강민물매운탕', 거주민들은 '곤드레 마늘솥밥', '올갱이 해장국', '남한강 민물매운탕과 회', '소백산 산채비빔밥'을 높게 인지하는 것으로 나타났다. 따라서 집적화 특징을 갖고 있는 향토음식은 단지가 형성되어 많은 관광객을 유인하고 있는 반면에 최근에 개발된 고구려 음식은 영화셋트장 주변에 음식점 단지를 형성하고 지리적 표시제도 도입 또는 상품명에 단양을 넣어 인지도 제고와 지역경제 활성화에 도움이 될 것이다. 셋째, 선호도 분석에서 남성은 '마늘육회', 거주민들은 '곤드레 마늘솥밥', '올갱이 해장국', '소백산 산채비빔밥', 50대는 '곤드레 마늘솥밥', '남한강 민물매운탕', '소백산 산채비빔밥을 더 선호하는 것으로 나타났다. 따라서 향토음식을 선호하는 노년층과 달리 젊은층을 어필할 수 있는 음식 맛과 각 재료의 대표적인 음식효능을 이용하여 선호도를 강화시켜야 할 것이다.
