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.

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.

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.

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.

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.

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.

본 연구의 목적은 부모가 정한 규칙에 대한 청소년의 준수 의무감 정도에 따라 청소년이 문제행동(음주와 타인 소유물 파손행동)을 하는 친구의 영향을 받는 정도에 차이가 있는지 알아보는 것이었다. 우선, 친구의 문제행동 정도에 따라 청소년의 문제행동 가능성이 높아지는지 살펴보았다. 다음으로, 친구의 문제행동과 청소년의 문제행동 간의 관계가 부모가 정한 규칙을 지켜야 한다구 믿는 정도에 따라 다른지 살펴보았다. 연구 대상은 미국 동부 지역 소도시 소재 중학교에 재학 중이 남녀 중학생(6학년∼8학년) 398명이었다. 자료는 참여 학생들이 부모 자녀 관계, 문제 행동, 친구 관계 등에 관한 항목으로 구성된 질무지에 응답하게 하여 수집하였다. 위계적 희귀분석을 사용한 자료분석 결과, 친구의 문제행동 정도가 심할수록, 부모가 정한 규칙에 대한 준수 의무감이 약할수록 청소년의 문제행동 정도가 심한 것으로 나타났다. 그러나, 친구의 문제행동과 청소년의 문제행동 사이의 정적 관계는 청소년이 부모가 정한 규칙을 준수해야 한다는 의무감이 약할수록 약한 것으로 나타났다. 이 연구의 결과는 청소년기 또래 영향 연구에서 청소년의 개인적인 특성을 고려하는 것이 중요하다는 것을 시사한다. 또한, 청소년이 부모가 정한 규칙을 지켜야 한다는 의무감을 갖도록 부모가 자녀와 원만한 관계를 유지하는 것이 부정적인 친구의 영향으로부터 청소년을 보호나는 한 방법이 된다는 점도 시사한다.
