Korea's fisheries both in quantity and in quality haves seen a remarkable growth since 1960's. Korea's inshore fisheries. However, haves been very stagnat since 1980's, with the deep-sea fishery daunted by the 200 sea mile economic water zones declared by inshore nations and sea resources getting exhausted by over-fishing. Korea's fisheries, accordingly, is in urgent need of reconstruction towards the transition from fisheries as exploitation of resources in the the past of fisheries as control of resoursces. A plan for a rational control of fisheries as control of resources is suggested as follows: 1. Control of the number of fisher boats to arbitrate fishing efforts. 2. Control of resources through dropping artificial nests, and producting and planting seeds and small fish, and caring for them. 3. Minimization of sea pollution and damage of fishing grounds owing to reclamation or filling up of inshore land. 4. Fundamental measuress to eradicate illegal fishing. This plan should be supported by amendment of laws and regulations and more progressive adjustment of the budget, if the plan is to be put into practice.

Gamma-Aminobutyric Acid가 고양이 적출 심장에 미치는 영향

이계열 고려대학교 의과대학 1966 고려대 의대 잡지 Vol.3 No.1

γ-Aminobutyric acid (GABA) occurs naturally in the brain and is formed by decarboxylation of glutamate by an enzyme more concentrated in the central nervous system than in other tissues. GABA has been identified by Florey as a component of inhibitory factor which can be extracted from mammalian brain, and which diminishes the discharge of impulse in the mechanically excited crayfish stretch receptors, the impulse generation in the cardiac ganglion and the neuromuscular transmission. The author and other investigators have been reported that GABA produced the initial inhibition of cardiac activity of the frog followed by the positive inotropic action. In this study, to investigate the role of GABA on the mammalian cardiac activity, the isolated heart of cat had been perfused with Ringer-Locke's solution according to Langendorff technique. The final concentration of drugs perfused with Ringer-Locke's solution were 3 mg/ml GABA-Ringer's, 12 ㎍/ml adrenaline-Ringer's, 2 ㎍/ml acetylcholine-Ringer's and 0.014 mg/ml atropine-Ringer's solution. Results obtained may be summarized as follows: 1. GABA inhibited the cardiac activities initially and soon being recovered, one minute later the heart produced more greater amplitudes of contractions as compared with those before GABA perfused. 2. GABA inhibited the cardio-tonic effect of adrenaline. 3. GABA potentiated the cardio-inhibitory effect of acetylcholine. 4. Initial negative inotropic action of GABA could not be identified after atropinization.

산소분압 변동이 혈액 및 여러 장기에 미치는 영향 : Ⅰ.혈액성분, 조혈기능 및 심장에 대한 영향 1. The Effects on the Erythrocyte, Erythropoietin Activity and the Heart Metabolism

To investigate the effects of hypoxic and hyperoxic conditions on the erythrocyte, erythropoietin activity and heart metabolism, this experiment was performed to the animals of 24 rabbits and about 300 mice. Hypoxic condition was induced by flowing the gas mixtures which contain 8% oxygen and 92% nitrogen into a closed hyperbaric chamber, and hyperoxic condition by flowing the gas mixture containing 40% oxygen and 60% nitrogen for 5 hours per day during the period of 15 days respectively. The flow rates of each gas mixtures were corrected by analyzing the oxygen content of outlet gases with micro-Scholander apparatus. Blood samples were obtained from the ear vein with heparinized syringes at the end of one-week and two-week exposure for the detemination of RBC, hemoglobin, hematocrit and RBC fragility and also arterial blood serum was collected and stored in freezer for the measurement of erythropoietin activity. This serum was injected subcutaneously to the plethoric mice and determined 59Fe incorporation rate. Oxygen consumption and lactic acid level of left ventricle excised from the heart of sacrificed rabbit were determined. The results obtained were as follows: 1. The increase of RBC count was more prominent in hypoxic group than in hyperoxic group. 2. Hemoglobin and hematocrit were increased significantly in hypoxic group and decreased in hyper Toxic group. 3. MCV, MCHC and MCH were increased in hypoxic group and decreased in hyperoxic group representing macrocytic shift in hypoxia and microcytic shift in hyperoxia. 4. Erythrocyte fragility was decreased in hypoxic group and increased in hyperoxic group. 5. Erythropoietin activity was increased in hypoxic group significantly, and decreased in hyperoxic group. 6. Oxygen consumption arid lactic acid level were elevated in hypoxia and depressed in hyperoxic group.

In order to study the electrocardiogram of small animals authors deviced a fixing apparatus in the ventral resting position of rabbit and an attaching electrodes. Normal electrocardiograms of 8 adult rabbits were studied with author's improved fixing apparatus and electrodes. Leads taken were the standard limb lead, augmented unipolar leads and the unipolar precordial leads. The total numbers of various leads were eleven altogether. Results obtained in this study may be summarized as follows: 1. The details of the methods used to record and measure the six standard frontal plane leads and the five precordial leads of the rabbit electrocardiogram in the ventral resting position were described. The fixing apparatus of rabbits in ventral position are shown in Figure 1 and the attaching electrodes are shown in Figure 2. 2. The electrocardiographic changes in ventral position were more stable than in dorsal position in each lead. 3. The analysis of the amplitude, duration and other values of various waves are shown in Table 1 and Figure 3. 4. The electrocardiogram of rabbits showed decreased heart rate in ventral position than dorsal one. 5. The mean electrical axis of QRS complex in ventral position were +44.12 degrees and in dorsal position were +25.5 degrees.

漁業賃金制度의 形成過程에 관한 硏究

이계열 여수대학교 1997 論文集 Vol.11 No.1

The fishing industry cannot be performed through individual labor because it's labor field in on sea and the objects of fishing are continuously migration, which requires cooperative labor of a large number of crewmen. The fishing industry with fisherboats which needs fishing implements as well as fisher boats was, from the beginning, conducted by a manager who could afford enough fund and labor force and it was done through a mangerial type of guild. That guild type management led to a distribution type in which the product is divided among the participants according to their roles and results. The role distribution system lasted for a long time because the system stimulated the zeal for production of the crew and the risks from uncertainty of the industry could be shared between the boat-owner and the crew. As the size of the fishing-boats grew, the early pure role-distribution system developed into minimum wage guaranting role-distribution, into fixed wage plus role-distribution, and then into fixed wage system. Korea's fishing industry has been changing its wage system from minimum wage guaranteing role-distribution, to fixed wage plus role-distribution, and to fixed wage system, with the development of near-sea and far-sea fisheries in the late 1960's and the growth of fisher-boat size and the development of industrial structure.
