A rational positive real function having simple poles, complex poles and arbitrary zeros in the s-plane has been investigated. The positive real fuction is realizable as an impedance function of RLC networks formed by connecting simple RLC subnetworks in series or in parallel. The realization conditions were obtained, and as an example, an RLC impedance function for the rational positive real function was synthesized.

51 male subjects aged 12years were devided into normal group(17), hearing handicapped group(17), and crippled group(17). After running 60m the cardiopulmonary response of the heart rate, blood pressure, and respiratory rate were measured and analyzed in order to find out the physiological differences among the three groups. The result were summarized as follows. <In resting stage> 1. Hearing handicapped group showed a little higher blood pressure than cripped group, and almost the same as normal group. 2. Hearing handicapped group showed almost the same respiratory rateas normal group and noticeably higher than crippled group. <After running bom> 3. Hearing heandicapped group showed 146.25% increase of the systolic pressure than in vesting state, crippled group 153.13% increase, and normal group, 133.03% increase. In short hearing handicapped group's systolic pressure after exersise was noticeably higher than crippled group's and almost the same as normal group's. Hearing handicapped group's diastolic pressure also increased 112.74% and normal group's increased 129.40%, and normal group's increased 104.65%, that is, hearing handicapped group's diastolic pressure was remarkably higher than crippled group's and almost the same as normal groups. 4. In heart rate, hearing handicapped group showed 142.03% increase than in resting state crippled group, 142.06%, and normal group 140.66%. In short, hearing handicapped group and cripped group a little higher increase of heart rate than normal group. 5. In respiratory rate, hearing handicapped group showed 166.46% increase than in resting state, crippled group, 159.68%, and normal group 134.93% that is, hearing handicapped group's and crippled group's respiratory rate was significantly higher than normal groups. We need to pay attention to the result of this research that in cardiopulmonary response in resting state, respiratory rate was noticeably lower in crippled group than in hearing handicapped group, and normal group, and in cardiopulmonary response after exercise, hearing handicapped group's heart rate, blood pressure, and respiratory rate were higher than crippled group's and lower than normal group's. It is necessary to mak deeper research on psychological, analytical, and physiological aspects, based on the this research.

It is necessary for managing a perfect process for degasing aluminum molten metal according to the increase of a grade of aluminum and its alloy products. There are some methods that have been used to manage a degasing process in recent years, such as an injection method that uses aluminum molten metal powder and chemicals supplier and input method that supplies argon and nitrogen, or chlorine gas by using a gas blow-tube. However, these methods show some problems, and it shows that it is a difficult process to handle, pollution due to the producing a lot of toxic gases like chlorine and fluoride gas, irregular effects, and lowering work efficiency due to the excessive processing time. The problems that are the most fatal are the producing a lot of sludge due to the reaction of aluminum molten metal with chemicals, loss of metals, and decreasing the life of refractory materials. In order to solve these problems, this paper develops a technology that is related to aluminum continuous casting molten metal and monolithic degasing apparatus. A degasing apparatus developed in this study improved the existing methods and prevented environmental pollution with smokeless, odorless, and harmlessness by using a new method that applies argon and nitrogen gas in which the methods used in the West and Japan are eliminated. The developed method can significantly reduce product faults that are caused by the production of gas and oxidation because it uses a preprocessed molten metal with chemicals. In addition, the amount of the produced sludge can also be reduced by 60~80% maximum compared with the existing methods. Then, it makes it possible to minimize the loss of metals. Moreover, the molten metal processing and settling time is also shortened by comparing it with the existing methods that are applied by using chemicals. In addition, it does much to improve the workers' health, safety and environment because there is no pollution. The improvement of productivity and prevention effects of disaster from the results of the development can be summarized as follows. It will contribute to the process rationalization because it does not have any unnecessary processes that the molten metal will be moved to an agitator by using a ladle and returned to process for degasing like the existing process due to the monolithic configuration. There are no floating impurities due to the oxidation caused by the contact with the air as same as the existing process. In addition, it can protect the blending of precipitation impurities. Because it has a monolithic configuration, it can avoid the use of additional energy to compensate the temperature decreasing about 60? that is caused by the moving of molten metal. It is not necessary to invest an extra facilities in order to discharge the gas generated from a degasing process by using an agitator. The working environment can be improved by the hospitable air in the factory because the molten metal is almost not exposed in the interior of the area.

The changes of peroxidase activities in the etiolated seedlings of DongJinbyeo under various stresses such as dehydration, wound, temperature, salt and heavy metal were investigated. Interestingly high temperature stress enhanced total peroxidase activity of the stem, while it reduced enzyme activity of the root. Moreover, 3 fold and 2.5 fold increase of total peroxidase activity occurred with PbCl2 and CdCl2 stress, respectively. These results suggest that the increases of total peroxidase activities might be involved in the defense mechanism against these stresses.

페미니즘 이론의 문학비평론적 적용에 대하여

This study aims to find possibility of using feminist theories as a guidance of interpreting modern korean feminist fictions. In this thesis the standpoints of different feminist theories are scrutinized and three feminist theories are selected to be used in classifying and interpreting different kinds of contemporary feminist fictions. As a result, Enlightenment Feminism, Existentialist Feminism and Cultural Feminism are found to be helpful as a analyzing tool of contemporary korean feminist fictions such as "Are You Still Dreamining?", "Dreamer's Incubator" written by Wan Seo Park, "Evening Party" by Jeong Hee Oh, and "the Place where Organ was Seated" by Kyoung sook Shin.
