In this study, the total bacterial count and coliforms MPN in samples stored at 5℃ investigated. The distribution, biochemical character and growth temperature of Psychrotrophic coliforms isolated from samples during cold storage were studied, also. The results were as follows : 1.The increasing rate of Psychrotrophic bacterial flora in samples was higher than that of Psy-chrotrophic coliforms. 2.In 213 strains of coliforms isolated from samples, 181 strains were Psychrotrophic coliforms. 3.The isolated Klebsiella aerogenes and Citrobacter freundii from samples were superior in number, showing 106 strains for Klebsiella aerogenes while 54strains for Citrobacter freundii. 4.The number of Klebsiella aerogenes and Citrobacter freundii of isolating Psychrotrophic coliforms showed maxima compared with others of Psychrotrophic coliforms.

In order to estimate the influence of free Oxygen absorber Na2S2O4 on the quality of perilla oil, the changes of acid value, peroxide value, and TBA value during storage at 40℃ were tested. The result were obtained as follows. (1) The acid values began to show high values in control group from the 7th day and in BHA group from the 14th day, but in Na2S2O4 group, they showed lower values than the others during storage. (2) In control group and BHA group, the peroxide values began to increase suddenly from beginning and showed the highest value from the 14th day to the 21st day, while the value of Na2S2O4 group showed the lower increasing tendency within 21 days, and then increased a good deal on the 28th day. (3) The TBA values were lower in BHA group than in control. Particulary the Na2S2O4 group showed the lowest values all of the others. (4) It revealed that sodium dithionite could prolong the induction period of period oil during storage at 40℃. In consequence, the effect of sodium dithionite on perilla oil during storage at 40℃ could be recognized.

There are the difference of nutritive contents of foods according to the area of production and the growth. To know the difference, I studied for the contained quantity of minerals in vegetables produced in Kunsan area. Water and ash were analized by general methods. Phosphorus and ion were studied by spectrophotometric absorbance. Calcium was analized by potassium permanganate titration. The results were as follows; Comparing with the analysis table of Nutritive Value in Korean Foods and of Central Chemistry Lab., the difference of contents was showed in some vegetables; The values of iron showed the defference in spinach, green onion and carrot The phosphorus contents showed the difference in onion, green onion and chinese cabbage. Calcium values were different from the preceding analysis tables in chinese rsdish, carrot and chinese cabbage.

Monkfish and it's liver went on increasing in demand by capturing the public fancy as a favourite food and their export. The control on various denaturation and drip of monkfish muscle during frozen storage is very important problem for keeping on their good quality and increasing their export. In order to investigate the effect of phosphates on the denaturation of monkish muscle during frozen storage, the solubility of salt soluble protein, thaw-drip, absorbed phosphorus, volatile basic nitrogen, thiobarbituric acid value and brown-pigment density were examined. 10% simple solutions and mixed solutions of sodium tripyrophosphate, sodium pyrophosphate and sodium metaphosphate were prepared respectively as table 1. The muscle from the underside of abdominal cavity to the upper side of tail was cut into fillets(3cm x 5cm x 10cm) and then the filets were dipped in the phosphate solution for 5 minutes respectively. Then the samples were sealed up into polyethylen bags and kept frozen at -20℃. The experiments on denaturation in the muscle were carried out 3 times at intervals of 20 days. The results were summarized as follows: 1) Phosphorus contents remained in the muscle were within the tolerence limit by FAO/WHO. 2) The free drip quantity released from the samples treated with phosphate was remarkably decreased than that of the control sample. Among the samples, No. 7 sample showed the least quantity. 3) The solubility of salt soluble proteins in muscle treated with phosphate was not decreased than that of the control remarkably. Therefore it was considered that the effect of phosphate on the muscle was effective. Among the samples, No. 7 was most effective. 4) It revealed that the sample showed in the higher contents of remained phosphate showed a tendeney to less released drip, and it caused a tendeney to enhancing of solubility for salt soluble protein. 5) The variation of brown-pigment density, volatile basic nitrogen and TBA-value were not remarkable.

To estimate the effect of free oxygen absorber on the rancidity and pigment of prepared laver, the PoV., TBA V and pigment quantity were examined during storage. The Laver was seasoned with oil and salt, and heated at 120℃ for 30 sec. Each a certain quantity (about 1.5g) of the laver was packed into gas-proof laminate bags in 4 groups; a group packed with sodium dithionite, a group packed under 74mmHg, a group packed with about 150ml of nitrogen and a group packed with about 200ml of air. All the samples were kept at 40℃±1℃ in incubator for 35 days and used at a week intervals for the experiment. The results were as follows : The PoV, TBA-V in N2 package group, vacuum package group and sodium dithionite package group is lower than those of control group (air package group). Particulary the values of sodium dithionite package group were lower than others. It revealed that the sodium dithionite influenced on the stability against the rancidity. In pigment quantity the values of sodium dithionite group consistently were higher than others in the longer period during storage as well. It revealed that sodium dithionite was effective in retarding the rancidity.

1. This study was included 8 patients with SAD, 8 patients with MAD, 7 patients with ADMC, 6 patients with MC alone and 7 subjects with control in order to evaluate the cell-mediated immunologic change after viral infection of MC. 2. With Sta. aureus antigen, PPD antigen and candidin, skin test reactivity would appear to be no significance between control and various diseases. 3. In PHA-induced stimulation, patients with AD showed decreased responses than control, but there was no differences (P > 0.05). By contrast, patients with ADMC showed significantly lower response than control and patients with MC alone (P< 0.05). 4. In PPD-induced stimulation, comparison of mean responses showed no significant differences between control and selected group (P> 0.05). 5. There was no difference in spontaneous transformation on 3-day and 5-day cultures (P> 0.05). Therefore, further study will be needed for the effect of molluscum virus on cellular immune reaction of AD.

A Study of the Relation between Laver(Porphyra Tenera) Production and Sea Water Temperature

Chyung, Moon Ki 慶熙大學校 1967 論文集 Vol.5 No.-

韓國沿海에는 海苔養殖用原藻가 Porphyra Tenera를 爲始하여 都合 10種이 알려져 있다. 이들 原藻의 胞子는 秋節에 海水中에 放出된다. 이 放出된 胞子는 죽홍망홍 및 巖石等 附着物에 附着하여 成長한다. 韓國과 日本에서는 이들 胞子附着物을 沿岸淺海에 人工으로 設置하는 海苔養殖業이 發達되고 있다. 韓國의 海苔養殖業者는 約 20萬名에 그 生産量은 1,000萬束(1束 100枚) 2,000萬弗內外이고, 그 輸出量은 約 370萬束(1束當 2弗內外) 740萬弗에 達하는 重要水産物의 하나이다. 그러나 이 海苔養殖作況은 每年 漁場內의 水溫, 流動, 比重, 榮養鹽類, 病菌 및 兩雪等에 依하여 그 豊凶이 左右된다. 이 豊凶이 素因中 가장 重要한 것은 水溫의 變動이다. 水溫과 海苔新長 및 作況의 豊凶에 關한 硏究는 日本의 富士用謬民를 비롯하여 殖田三郞, 黑木, 須藤, 成崎, 片田 等諸氏의 報告가 있다. 筆者는 1961年 乃至 1965年까지 5個年間의 水溫의 變動과 海苔作況의 豊凶과의 關係를 調査한 結果 아래와 같은 事項이 나타났다. 《結果》 1. 海苔胞子가 絲狀體에서 放出되어 海苔발(홍) 또는 巖石에 附着하는 胞子의 附着期前인 9月上旬의 水溫이 23.24℃ 以上 인해는 豊作을 豫想할 수 있고 反對로 9月上旬의 水溫이 20.66℃ 以下일 때는 凶作을 豫想할 수 있다. 2. 養殖初期인 9月上旬부터 12月下旬까지의 水溫變動이 比較的 高溫인 23.24℃ 以上에서 始作하여 順調롭게 降下하는 해는 豊作을 豫想할 수 있고 同養殖初 期中의 水溫變動이 比較的低溫인 20.66℃ 以下에서 始作하여 途中에 20.66℃ 以上으로 上昇했다가 다시 降下하는 等 水溫의 起伏이 있는 해는 凶作을 豫想할 수 있다. 3. 同養殖初期中의 水溫變動의 起伏의 回數가 많을수록 凶作의 程度가 甚하다. 4. 同養殖初期中에 있어서 不順水溫 變動의 起伏回數에 있어서 11月中旬 以後乃至 12月下旬間의 變動回數 보다 9月上旬 乃至 11月上旬間의 不順水溫回數가 있거나 또는 그 回數가 많을수록 凶作의 程度가 더 甚하다. 5. 養殖後期인 1月乃至 4月間의 不順水溫變動은 豊凶에 그다지 큰 影響을 주지 아니하였다.

이 연구에서는 어머니의 자녀 양육 행동에 대한 청소년과 어머니간의 지각 차이와 청소년의 적응을 연관시켜 고찰하였다. 자료 수집은 질문지를 통해 이루어졌으며, 참여자들은 미국 동부 소도시에 거주하는 82 명의 9 학년 남녀 학생과 어머니들이었다. 자료 분석 결과, 평균적으로는 어머니들이 청소년 자녀들보다 자신의 자녀 양육 행동을 더 긍정적으로 지각했다. 청소년의 적응을 어머니와의 지각 차이에 따라 살펴 본 결과, 어머니의 양육 행동을 어머니 보다 긍정적으로 지각하는 청소년들이 어머니 보다 부정적으로 지각하는 청소년 보다 문제 행동을 하는 경향이 낮았으며, 자신감은 높았다. 또한, 어머니의 양육 행동을 어머니 보다 긍정적으로 지각하는 청소년들이 그렇지 못한 청소년들에 비해 어머니와 원활한 의사소통을 하는 것으로 나타났다. 이 연구의 결과들은 청소년과 어머니 간의 지각 차이가 측정 상의 문제만이 아닌 청소년 발달과 연관있는 요인임을 지적한다. 그리고 지각 차이를 연구할 때는 그 차이의 크기 뿐 아니라 청소년과 어머니 중 어느 편의 지각이 더 부정적인지도 고려해야 한다는 점을 지적한다.
