朴榮浩,姜泳周 釜山水産大學校 1974 釜山水産大學 硏究報告 Vol.14 No.1

冷凍명태 fillet의 冷凍變性 防止에 미치는 各種 添加物處理의 效果를 試驗코져 fillet를 凍結前에 21種類의 處理液에 5分間 浸漬하여 凍結貯藏한 후 解凍하였 을때의 free drip, expressible drip의 發生量 및 drip中의 total solid, nitrogen, DNA의 含量을 定量하여 冷凍變性의 程度를 比較檢討하였다. 1. Free drip는 處理液의 種類 및 濃度에 따라 큰 差를 나타내었으나, expressible drip에 있어서는 그 差가 적었다. 2. Drip량의 減少에 있어 效果가 큰 處理液은 sodium polyphosphate 10%, sodium polyphosphate: sodium pyrophosphate(1:1) 10% 및 5%, sodium chloride 10%, sodium citrate 10%였다. Sodium metaphosphate, glucose, sucrose 및 sorbitol의 處理 效果는 그다지 크지 못하였고, malic acid 處理는 큰 逆效果를 나타내었다. 3. Drip中의 total solid 및 nitrogen은 大체的으로 drip量에 比例하는 結果를 보였으나, malic acid 處理區의 nitrogen量은 drip의 發生量에 비하여 相當히 적은 量을 나타내었다. 4. Drip中의 DNA量에 미치는 前處理의 效果는 drip發生量 및 drip中의 total solid, nitrogen의 경우 보다 현저하였고, 特히 重合燐酸鹽의 效果는 커서 sodium metaphosphate까지도 良好한 結果를 나타내었다. Malic acid 處理區는 drip量은 월등히 많은데도 DNA 含量은 微量에 지나지 않았다. The present study was conducted to evaluate the effect of prefreezing treatment, dipping the fillets into such solutions as condesed phosphate, sugars, and sodium chloride, upon the freezing denaturation of Alaska pollack muscle. The degree of freezing denaturation was estimated by measuring the amount of drip released, contents of total solid, total nitrogen, and DNA in the drip. Fillets were frozen at -27℃- -28℃ and stored for 20 and 40 days at -18℃- -20℃ . The amount of free drip was greatly dependent on treating solution although the expressible drip was not so much variable. Among the treating solutions examined, 10% sodium polyphosphate, 5% and 10% of the mixture of sodium polyphosphate and sodium pyrophosphate (1:1 w/w), 10% sodium chloride, and 10% sodium citrate appeared most effective ones to retard the releasing of drip. The effect of sodium metaphosphate, glucose, sucrose, and sorbitol was not so benefitable. On the contrary, malic acid showed a remarkable reverse effect. As a tendency, total solid, total nitrogen, and DNA in the drip varied proportionally to the amount of drip released. Releasing of DNA, however, was greatly affected by treating solutions comparing with that of total solid and total nitrogen. It was not the case in malic acid treated fillet particularly in DNA content, even though the amount of drip was greater than other cases, DNA content was far less.

To evaluate the composition of Gae-Woo Jeot which is one of important traditional salted and fermented sea foods in Cheju Do, changes of nucleotides and their related compounds, free amino acids, TMAO(trimethylamine oxide), TMA(trimethylamine) contents and histological properties during fermentation was examined. AMP was as high as 3.6?mole/?? in raw small abalone but IMP content was only trace while hypoxanthine and IMP was dominant in raw topshell-4.5 mole/?? and 4.3??mole/?? respectively. Hypoxanthine was predominant in 65 days fermented Gae-Woo Jeot. Main amino acid in Gae-Woo Jeot were glycine, arginine, glutamic acid, alanine, valine and histidine in order. These were consisted 50~60% of the total free amino acid while phenylalanine, tyrosine, methionine and isoleucine were poor in content. During fermentation TMAO decreased slowly and eventually disappeard within 85 days while TMA was increased until 65 days and started to decrease down to 6~9mg%. Muscle texture showed the disappearance of elasticity soon after the adding of 10% salt while no change of texture was oberved until 50 days of fermentation in 20% salt group.

It is well known that pipelines have the highest capacity and are the safest and least environmentally disruptive form of transporting oil and gas. However, pipeline damage caused by both internal and external corrosion is a major concern threatening the reliability of oil and gas transportation and the soundness of the pipeline structure. In this study, we estimate the allowable damage by comparing the ASTM B31G code to a modified theory considering diverse detailed corrosive forms. The ASTM B31G code has been developed as the evaluation method for reliability and incident prevention of damaged pipelines based on the amount of loss due to corrosion and the yield strength of materials. Furthermore, we suggest a method for estimating the expected life span of used pipelines by utilizing the reliability method based on major variables such as the depth and length of damage and the corrosion rate affecting the life expectancy of the pipelines.

無基準豫算에 있어서 事業順位決定過程에 관한 硏究

朴英熙 건국대학교 1978 學術誌 Vol.22 No.1

The ranking process in zero-base budgeting is the listing of decision packages in order of deceasing benefit or importance to the organization so that management can allocate its resources by determining "how much should we spend? and where should we spend it?" The ranting itself identifies and recommends where money can best be spend. Management must then decide how much should be spend, and must determine the cut-off level of funding. In this final decision, top management must determine both what amount of funding the organization can afford to do without. The packages alone do not identify organizational priorities. To make the zero-base -budgeting process meaningful, each organization needs an effective ranking procedure to put the packages in priority order. The decision package ranking serves primarily as a summary sheet to identify the order of priority placed on each decision packages. The ranking form should provide enough information to satisfy basic needs of top management, with the decision packages available so that management can review some or all packages at its discretion. The number of decision packages created in a large organization by effectively identifying each discrete activity, including several levels of effort, could present a difficult or impossible task to top management if they had to review in detail and rank every decision package. Yet management has the conflicting need to make funding trade-off among all activities in the organization that are competing for the same resources. This problem can be solved by: 1. Concentrating management's review on lower priority or discretionary packages around which the funding bevels or cutoff will be determined. 2. Limiting the number of consolidation levels to which the packages will be merged.

Kinetic studies of the solvolysis reaction of benzoy1 chloride have been carried out in such binary solvents as acetone-water, ethanol-water, methanol-water and acetonitrile-water by the conductometric measurements. Measuring the conductance of the benzoyl chloride solution in the binary aqueous solvents, the pseudo-first-order rate constants were obtained at 0°C and 10°C. According to the transition state theory, activation free energy, △G°, activation enthalpy, △H°, and activation entropy, △S°, were also evaluated. The results showed that the bimolecular process predominates in the low water content region but Sn1 process becomes increasingly important in the high water content solvent composition. The isokinetic temperature(Tiso) from the isokinetic relationship between △H° and △S° was 266°K. In the results, the reaction rates were faster in protic solvents than in aprotic solvents. In the solvents of similar property, however, the reaction rate in the solvent of the large dielectric constant was faster than that in the solvent of the small dielectric constant. Kirkwood plots at individual temperatures showed the straight lines with positive slope; and the slope of the line at 10°C was smaller than that at 0°C. By the kinetic analysis, we concluded that the solvolysis reaction of benzoyl chloride occurred via the bimolecular addition - elimination mechanism.

This paper deals with the differences between the thermal stabilities of myofibrillar proteins of dorsal ordinary muscle and lateral dark muscle in yellowtail, Seriola quinqueradita. The myofibrillar proteins submitted to this experiment were extracted by the modified method using Triton X-100 detergent. Effects of temperature on the stabilities of the myofibrillar proteins were investigated by analysing ???-ATPase activity. The denaturation velocities and thermodynamic parameters of each of the proteins were compared. Lipid content and ???-ATPase activity of the myofibrillar protein of the ordinary muscle were found to be 0.09% and 0.205-0.225μM-Pi/min/mg-protein, respectively, while those of the dark muscle were 1.70% and 0.231-0.240μM-Pi/min/mg-protein. The relationship between the inactivation of ???-ATPase activity of the myofibrillar proteins and the increase in temperature showed a good first-order reaction. The half-life of ???-ATPase activity on the myofibrillar protein showed in general that the protein of the ordinary muscle is more stable than that of the dark muscle. Activation energy, activation enthalpy, activation entropy and free energy of the protein at 25℃ were 5,500 cal/mol, 4,900 cal/mol, -44.51 e.u. and 18,100 cal/mol, respectively for the ordinary muscle, and 5,390 cal/mol, 4,800 cal/mol, -44.17 e.u. and 17,900 cal/mol, respectively for the dark muscle. It may be concluded that an increase in temperature affects substantially to entropy of the proteins. The myofibrillar proteins of the both muscles found to be more stable at -30℃ than at 0℃ and -15℃.
