  • The purposes of this study are to evaluate the utilization characteristics of electrical power consumption, to grasp the present trends in the use of electrical equipments, to estimate the demand factor and load factor being held, and to evaluate the efficiency of electical uses for the recently electrified farms cultivating paddy rice. For the purposes, 109 sample farms located in eleven villiages electrified in six different years from 1968 to 1973, were chosen at random and investigated on 35 items concerning to electrical uses and wiring systems. The survey was carried out in 1975, in the vinicity of Suweon city. The results are summarized as follows: i) The average annual power consumption on sample farms is considered to be low, being 242.9 Kwh. in 1974, and varied according to the different electrified year and size of cultivated land, respectively. It has significant positive correlation to the area of farm, too. ii) Between the number of year of electrical uses and the power consumption, there is very significant positive correlation, which could be expressed as Y=43.041+16.108 X, where X represents the number of years of electrical uses. The annual increment of power consumption is much greater at the beginning of the electrification than that at the later years, its average being approximately 20 percent. However, it is recommended that any estimation of long-term increments should be carefully investigated. iii) The monthly power consumption varies considerably throughout a year, in which the heaviest farm load occurs in November. Observing the seasonal variation of consumption, the winter-time is the heaviest season while the summer is the lowest. The result implies house lighting is chief contribution to the present electrical consumption on the farms. Comparing the variation of monthly consumption ratios between the sample farms and industries, the electrical uses on the farms are independant of the industrial uses, and further, the agricultural uses are of inverse pattern to the farms from the results that there is negative correlationship between them, iv) The number of electrical equipments used on the farms are occupied chiefly by lighting sources. Next to the lighting sources, household appliances of small quantity and some motors are used. The mean electrical quantity is about 1, 127.4 watt, which corresponds to about 37.6 per cent to the contracted quantity. The composition of quantity is chiefly occupied by the electrical motor of about 1.5 hp., single-phased. The number of the annual utilization hours of each equipment is tabulated in Table IV-5. In contradiction to the high utilization of lighting sources and small household appliances, the motor is poorly used for approximately 22 hours in a year. v) More than 55 per cent of farms want to purchase new electrical equipments such as small household appliances and electrical motors in their number. The impulse of purchasing such items is stimulated by the contacts to the mass media and their knowledge on such equipments. Consequently, the increase of electrical uses could be prompted by such trials as education and demonstration. vi) The demand and load factors on the farms vary considerably according to the greater variation of the power consumption, daily or monthly. The daily demand factor is 22.4 per cent and load factor 18.6 per cent, while the annual demand factor is 1.3 per cent and load factor 70 per cent approximately. Therefore, the low efficiency of construction cost requires re-evaluation of the present contracted quantity of 3 Kw. or increase of electrical uses. vii) The electrical energy on the farms devoted chiefly to lighten the farm residences does not contribute to the farm incomes. Consequently, the cost of electrical consumption presses considerably upon the farm economy. Therefore, there is great need to build up the electrical uses on the farms through the development of new works and techinques to utilize any electrical equipments on the production of farm products. Further more, such the development should be related to increase the actual income of the farm consumers.

  • This work has following two research goals. First, IVF treatments that have been recently going on in Korea are reexamined from the perspective of women's reproductive rights. Second, the intimate connection between IVF and therapeutic cloning research, in that remnant embryos and eggs that have been secured through IVF treatments have served as a main source of supply for therapeutic cloning research, has been emphasized. The fact that the influencing power of tradition on Korean families and women and IVF techniques eventually joined their hands in support of therapeutic cloning research is noted. Analysis of experiences of infertility by women in the realms of family, medical care during IVF treatment, and therapeutic cloning research that requires continuous supply of eggs leads to following conclusions. First, in the realm of family, infertile women were not only relegated to the status of abnormality but pressured to question their own womanhood. Under this circumstance, IVF treatment helped to reinforce the traditional concept of biological motherhood, thus categorizing married women giving birth to babies and married women who can't or refuses to do so to 'normal ones' and 'abnormal ones' respectively. Second, in the realm of medical care an infertile woman could rediscover her own body during the process of IVF treatment. By going through the processes of hormone treatment, implantation, conception, miscarriage, and so on, she could realize that her own body is understood in diverse ways to her, her family, and the medical profession. Third, in the realm of the state, IVF treatment that was serving as the main supplier of research materials for therapeutic cloning research has been able to avoid controversy in public discourses since the latter has emerged as a signifier of new national economic workhorse for the 21st century. As therapeutic cloning research went into high gear, the status of women as egg providers began to assume a political dimension. Women as egg providers are called upon to take on a paradoxical role as patriotic contributors to national economy on the one hand and as guardians of sacred 'life' on the other hand. The direction and progress of the research will depend on the ways that women comply, compromise, and/or resist the contradiction brought about by being assigned to assume these two identities: the one as a member of the nation requested to serve as a part of national economic development project, even though considered ineligible for financial recompense, and the other one as a guardian of sacred 'life,' even though she have to serve the research that is allowed to create a 'life' to destroy a 'life.'

  • This study aimed to reconsider the theory that the renowned Amisan(峨眉山) terraced garden at north of Gyotaejeon(交泰殿) was artificially made, by reviewing the historical records and drawings. It has been widely accepted that Amisan was made of the digged soil from Gyeonghoeji(慶會池). But several arguments about artificial mountain theory of Amisan that completely not be found in historical records have been raised in this study. The results were summarized as follows; the inherent contradiction in existing opinion, the discordance between the time of building Gyeonghoeji and Gyotaejeon, the existence of the mountain range which connect Baekaksan and Amisan appeared in Dohyeong(圖形), historical documents written in the years of kingdoms of Youngjo(英祖) and Gojong(高宗), a high position seen from Heungbogjeon(興復殿) in the north Amisan through the wall in the east but impassable, an opinion about realization Amisan as geomantic term of Amisa(蛾眉砂) at the time of Gyeongbok Palace reconstruction, and preservation of the mountain range in Gyeongbok Palace that comes from the result of the arguments in main mountain of Gyeongbok Palace in the year of Sejong(世宗). In addition, it was investigated why the slop in the north of Gyotaejeon was named as Aminsan and why the artificial mountain theory is appeared and made a conclusion that the Amisan comes from the change of the pronunciation of the geomantic term "Amisa", and modeling the yijing[意景] of Amisan which is a sacred place of Taoism and Buddhism in Sichuan[四川] of Chinaand the view of construction to mean defeating a spirit of smallpox which had to be cured. And it seems to be a result which retroactively applied the artificial mountain theory of Amisanis the technique of 'constructing mountain with digged pond dirt' to the relationship between Gyeonghoeji and Amisan. The greater part of mountain range which was connecting with Baekaksan and Amisan was seriously disconnected with large scale of exposition by the Japanese colonial period in 1915. But low slope is kept about 70 meters along the trail northeast of Gyotaejeon. Accordingly, it is judged that the range has not been entirely destroyed. And according to the result of elevation analysis, discontinuous slope form certain axis is found, so the mountain range of Amisan is approximately estimated. This basic research about the mountain range of Amisan might provide a critical clue about restoration of topography in Gyeongbok Palace.
