송대진,SONG Dae-Jin 한국수산과학회 1973 한국수산과학회지 Vol.6 No.3,4

생 전복을 액체질소동결, 송풍동결, 반송풍동결, 정지공기동결의 네가지 동결방법으로 동결하여 $-20^{\circ}C$에서 3개월간 저장하여 동결방법에 의한 전복근육의 물성적 변화, 단백질의 변성 등을 검토하여 다음과 같은 결과를 얻었다. 1) 생전복의 사후경직은 다른 어류보다 빨랐다. 2) 압측시험치, 전단시험치는 액체질소동결을 제외하고는 동결방법에 의한 차는 없었고, 저장기간이 길어짐에 따라 약간 감소하였다. 3) 염가용성질소는 동결저장기간중 용출량이 완만하게 감소하였다. 4) 유리수의 유출량은 패주와 다리 사이에는 차가 있었고, 저장기간중 패주는 유리수가 증가하는 경향이었다. 5) Texture의 Panel test 결과 저장기간을 통하여 Texture가 감소하는 경향이었으며, Texture의 변화는 유리수의 변화(P<0.01), 단백질의 변성(P<0.05), 압축시험치의 변화(P<0.05)와 유의의 상관관계가 있었다. 본 논문을 지도하여 주신 동경수산대학 교수 전중 화부 박사 그리고 논문의 작성에 조언해 주신 부산 수산대학 식품공학과 이응호 박사님께 감사의 뜻을 표한다. To study the effect of freezing rate on the duality of frozen abalone(Haliotis gigantea, GMELIN) liquid nitrogen spray freezing, air blast freezing, semi-air blast freezing, and still air freezing were carried out. The rheological change, protein denaturation, and free water content of frozen and thawed abalone were examined at the period of 0, 1, 2, and 3 month during cold Storage at $-20^{\circ}C$. The results are summarized as follows : 1. The onset and duration of rigor mortis of fresh abalone was faster and shorter as compared to that of fishes. 2. There was no difference in compression value and shear value between freezing methods but they varied with a slight decrease in storage period. 3. Gradual decrease in extractibility of salt soluble protein was observed in all samples except those frozen with liquid nitrogen. 4. The free water of the foot muscle remained constant during the storage while that of the adductor muscle tended to increase. 5. A significant correlation was observed among the changes of panel texture and free water (P< 0.01), protein denaturation (P<0.05), and compression value (P<0.01).

바다방석고둥육의 동결저장중 단백질조성과 근육조직의 변화

송대진(Dae-Jin Song),김창용(Chang-Yong Kim),박환준(Hwan-Joon Park) 한국식품영양과학회 1994 한국식품영양과학회지 Vol.22 No.6

바다방석고둥육의 보수성은 생시료의 경우 70%를 나타내었으며 -30℃ 동결저장은 동결직후에 비해서 거의 변화가 없었다. 그러나 동결저장 6개월째에 -18℃에서는 47%, -25%에서는 52%로서 저장기간이 길어질수록 보수성의 저하가 현저하였다. 근육단백질의 용출성은 근형질단백질과 기질단백질은 동결온도와 저장기간에 상관없이 비교적 안정하였으며, 근원섬유단백질의 용출성은 동결저장온도가 높고 저장기간이 장기화할수록 감소하였다. 근육조직구조의 변화에서 바다방석고둥의 근섬유는 평활근으로 횡단면과 종단면의 구분이 없이 가느다란 근섬유가 근육조직내에 치밀하게 분포하였는데, 중간부로 갈수록 약간 굵은 근섬유가 zig zag로 얼커져 있는 상태였다. 동결저장중의 조직구조는 동결저장온도가 높을수록 빙결정의 성장을 볼 수 있었으며 -18℃에서 3개월 저장한 조직에서는 근세포의 응집에 의해 공간 면적이 넓어지는 경향을 나타내었다. 그리고 해동후의 근육조직구조는 1개월 저장까지는 저장온도에 관계없이 잘 복원되었으나 -18℃에서는 복원 불충분에 의한 공간이 많이 남아 있었다. 이상의 결과에서 탈각후 전처리 한 바다방석고둥의 품질보존면에서는 일반 가정용냉동고에 채택되고 있는 -18℃와 -25℃의 동결저장온도는 3개월 이하의 저장에 효과적이며, -30℃에서의 동결저장은 보수성 및 근원섬유단백질의 용출성의 결과에서 비교적 장기저장에 적합한 동결저장온도로 검토되었다. To investigate the quality changes during frozen storage, top shell, Omphalius pfeifferi capenteri, was stored at -18℃, -25℃ and -30℃ immediately after shelling and water holding capacity, protein composition and histological features were examined with the lapsed period of the storage. During the storage period, amount of free drip was increased with higher frozen temperature and longer frozen period, but with the longer storage period, the lower water holding capacity was observed. The extractability and composition of muscle protein, sarcoplasmic protein and stroma protein were rather stable regardless of frozen temperature and frozen storage period. However, the extractability of myofibrillar protein was decreased with higher frozen temperature and longer frozen storage period. On the changes of muscle tissue structure, following points were observed. 1) In the muscle tissue structure of fresh sample, fine muscle fiber was closely distributed all over the tissue regardless of cross and longitudinal section. 2) In tissue structure under frozen state, it was observed that ice crystals apparently grew with the higher storage temperature. Empty spaces between muscle bundles which were formed by aggregation of muscle fiber were observed after 3 months storage at -18℃. 3) Tissue structure in thawed state was restored satisfactorily after 1 month storage regardless of storage temperature. After 3 months storage at -30℃, muscle tissue was well restored, but at -18℃, empty spaces were apparent due to incomplete restoration.

N/A Purpose: Appropriate reference values are needed for assessment of pulmonary function during childhood. We performed pulmonary function test with simple computerized spirometry to establish reference values of air flow rates in healthy Korean children. Methods: We examined 1,317 children aged 6 to 15 years at their schools by standardized method during May, 2001. The children with poor cooperation, respiratory symptom, and chronic disease were excluded. Regression analysis was applied for FVC, FEV1, PEF, FEF25-75% predicted from sex, age, standing height, weight, and body surface area. Results: In 1, 317 children(Male:716, Female:601) , the distribution of height was from 106.7 cm to 173.5 cm, weight was from 16.5 kg to 75.5kg. We could get regression equations and determinant coefficients between anthropometric parameters and air flow rates. In both sexes, height showed very close correlation with lung function variables, and FEV1 showed very close correlation with all anthropometric parameters. Reference values of pulmonary function test were generally higher in boys than in girls. Conclusion: After performing the pulmonary function test in healthy Korean children, we report their normal values of air flow rates and regression equations for the predicted values. Among anthropometric parameters, height showed most close correlation with lung function variables in both sexes.

To study ecological properties of Vibrio cholerae non-O1 and Vibrio mimicus which have been described as new food poisoning bacteria recently, the influence of factors such as temperature, salinity, pH and chemical oxygen demand (COD) on detection rate and density of these bacteria were evaluated. Fifty four seawater samples and 49 bottom deposit samples from estuary of Kum river from March 26th, 1993 to February 22nd, 1994 were used for this study. The detection rate of V. cholerae non-O1 were 16.7 for seawater and 10.2 for bottom deposit, respectively. The total detection rate of V. cholerae non-O1 (11.7%) was a little higher than V. mimicus (10.7%.) Both V. cholerae non-O1 and V. mimicus were mainly detected in estuary water of which showed temperature 24℃ above and salinity 10‰ below. These bacteria were also detected in bottom deposit on January when the water temperature was 3.5℃. From these results, we supposed that temperature, salinity and organic material were important factors to growth of V. cholerae non-O1 and V. mimicus. V. cholerae non-O1 might be grown better than V. mimicus under the fluctuating aquatic environmental condition such as salinity.

바다방석고둥을 원료로 한 신제품 개발에 관한 일련의 기초 연구로 저장성 부여를 위하여 시도하는 고온가열처리 조건 (F_0 5분, F_0 10분, F_0 15분 및 F_0 20분)에 따른 바다방석고둥의 성분변화에 대하여 살펴보았다. 바다방석고둥 통조림은 살균을 5분 이상 처리하는 경우 저장 중 팽창관이 발생하지 않았고, 또한 생균수가 검출되지 않아 저장성이 있었다. 고온가열처리 정도가 증가할수록 바다방석고둥의 일반성분 중 수분함량은 감소하였고, 조단백질 함량은 증가하였으며, 조지방 및 조회분 함량은 거의 변화가 없었다. 또한 바다방석 통조림은 고온가열처리 정도가 증가할수록 이취에 관여하는 휘발성염기질소 함량, pH와 색조에 관여하는 갈변도는 증가하였고, 영양에 관여하는 구성아미노산, 무기질과 맛에 관여하는 유리아미노산, TMAO, total creatinine 및 수율 둥은 감소하였다. 이들을 색조, 조직감 및 맛에 대하여 관능검사한 결과 자숙 처리한 시료에 비하여 모든 항목에서 F_0 10분까지는 차이가 없었으나, 그 이상 가열처리한 경우 품질이 저하하였다고 인지되었다. 이상의 결과로 미루어 보아 바다방석고둥을 고온가열처리하여 신제품을 개발하고자 하는 경우 F_0 값이 10분 이상이면 바람직하지 않은 것으로 판단되었다. The top shell, Omphalius pfeifferi capenteri meat vacuum-packed in can (diameter× height, 74.1 ㎜ × 50.7 ㎜) were heated at 115℃ up to F_0 values of 5 min, 10 min, 15 min and 20 min, and the changes in food components were studied. After 14 days storage at 37℃ and 55℃, no growth of microorganism and panelling were recognized from the canned meats which were sterlized at 115℃ with F_0 value of 5 min and over. In the case of proximate composition of the canned meats, the moisture content decreased with the increase of F_0 value, while crude protein increased. The increase of volatile basic nitrogen content, pH and degree of browning and the decrease of mineral, total amino acid, free amino add, trimethylamine oxide, total creatinine contents and yields were observed during thermal processing. In sensory evaluation on color, texture and taste in the canned meats, no significant difference was observed among a boiled sample and the canned meats heated at F_0 value of 10 min and below. But, in the canned meats heated at F_0 value of over 15 min, its sensory scores decreased with the increase of F_0 value. From these results, the reasonable F_0 value for preparation of the heat-treated top shell meats was in the range of 5∼10 min.

장수현,송대진,양송주,신일식,김영만 ( Soo Hyun Chang,Dae Jin Song,Song Ju Yang,Il Shik Shin,Young Man Kim ) 한국수산과학회 1995 한국수산과학회지 Vol.28 No.1

Vibrio cholerae non-O1 and Vibrio mimicus, food poisoning bacteria, have detected frequently in fresh water and brackish water. To estabilsh prevention measures of food poisoning outbreak by these bacteria, the adaptability and population changes were examined in fresh water, brackish water (10‰ NaCl) and seawater (30‰ NaCl). Both species poorly survived as temperature increased regardless of water types employed. However, survival time was the shortest in fresh water and longest in seawater at 4℃. In case of brackish water, the bacteria survived best at 15℃ and population were varied only in small numbers. Any significant difference was not observed to both species with respect to water types and temperatures except V. mimicus survived about 5∼6 days longer in brackish water. In conclusion, V. cholerae non-O1 and V. mimicus were not likely to be recovered in normal fresh water, brackish water and seawater, and both biological and physicochemical factors could affect survival of these species.

Cough is one of the common symptoms, which is usually related to respiratory infections for children. This symptom is not considered crucial. Published data reported that the community prevalence of chronic cough in primary school children is 5%-10%, while the prevalence is likely to be higher in younger children. The cause of persistent cough should be investigated. There were significant differences in the causes and management for cough according to age. Chronic cough is defined as duration of 4 weeks or longer. Common culprits for chronic cough in children are different from those in adults. The authors reviewed articles about chronic cough of children to help improve the understanding and management for pediatric chronic cough. (Allergy Asthma Respir Dis 2016: 4:235-247)
