정부에서는 최저가 낙찰제도의 무리한 저가투찰을 방지하기 위해 입찰가격 적정성 심사기준 등을 강화하고 있으나, 낙찰가율이 저하되는 근본적인 문제점이 여전히 상존하고 있다. 본 연구에서는 최저가낙찰제도의 입찰금액 적정성 심사기준 문제점을 분석하였으며, 그 결과 발주기관의 기초금액 결정요소의 제한적 공개, 5% 초과분 구분공종의 비율, 부적정공종의 제한적인 심사항목 등이 낮은 낙찰가율을 형성하는 주요 요인으로 파악하였다. 이에 본 연구에서는 기존의 입찰금액의 적정성 심사 절차상의 문제점을 개선 할 수 있는 방법을 제안하고, 적정낙찰가율 범위에서 낙찰자를 선정할 수 있는 입찰금액 적정성 심사 기준을 보완한 프로세스 모형을 제시하며, 기존 발주사례를 통하여 적정성을 검증하고 있다.

The purpose sof this study was to examine consumer's addictive buying through the TV home shopping, focused on materialism, show host and credit card use consumer. Two hundred four female consumers who had purchased fashion items in TV home shopping had participated for this study. For data analysis, descriptive statistics, factor analysis, t-test, and multiple regression were used for the study with SPSS 12.0 program. The result were as follows. First, the addictive buying group was 13.2% among respondents while non-addictive buying group was 86.8%. Second, materialism was classified into 3 factors: happiness, success and possessiveness. Show host was classified into 3 factors such as visual presentation, image and communication skill. Credit card was classified into 3 factors: sales promotion, late payment and method payment. Results of multiple regression revealed that happiness and possessiveness from materialism, credit card late payment, and show host communication skill were significantly related to addictive buying. Based on these results, this study would provide fashion marketing strategies for reasonable and reasonable consuming culture, since addictive buying has been not only individual problem but also social problem. Based on these results, this study would provide fashion marketing strategies for reasonable and reasonable consuming culture, since addictive buying has been not only individual problem but also social problem.

"Bioethics" may have various meanings depending on its roles. It may mean professional ethics for scientists and physicians, etc. It may also mean an academic discipline using interdisciplinary approach as well as a philosophical or a legal approach. "Bioethics" as an interdisciplinary study should often deal with public policy on bioethical issues. I call this role bioethics as a study of bioethics policy, which has to be developed as a new discipline. From this perspective, I deal with bioethical issues relevant to a human life before birth. There are various and often conflicting arguments about the moral status of a human life before birth such as the fertilization argument, the argument of genetic identity, so-called the "14 days" argument focusing on the formation of primitive streak, the argument of sentient being, and Michael Sandle's argument of an embryo as a being between a thing and a person. I argue that each of them is reasonable. Thus we are faced with reasonable disagreement on the views over whether a human life before birth has the same right to life as that of a person or whether right to life may be considered to be a matter of degree. If we acknowledge reasonable disagreement, as John Rawls pointed out, we should tolerate the views from ours in a plural society. Therefore, we cannot help making a policy that allows abortion and embryonic research with some limitations. When we say a certain act is morally permissible, "moral permissibility" does not mean that the act is morally right for all. Rather it means that the act cannot help being morally allowed for some persons although the others do not believe its moral rightness because they cannot right now rationally persuade others to accept their view.

This study analyzed the degree of demand for genetically modified organisms(GMOs) to provide the basic information for consumers' reasonable purchase decision making and their right to know about GMOs. Based on the (Ed-there are no study results above) study results, the following suggestion were made. First, throughout the survey, it was found that those consumers who participated had a high level of perception on the harm of GMOs. Therefore, reliable organizations such as government agencies are required to present the results of safety tests and formulate plans related to the safety of GMOs. Second, the average score on consumers' level of consumer knowledge on GMOs was very low, being 1.68 out of a possible 8 points. Third, since women and housewives engaged in dietary habits and food had high demand for information on GMOs, it is necessary to provide women with information on GMOs. Fourth, since it is difficult to confirm the presence or absence of GMOs. in rapidly increasing demand for fast-food, it is necessary that consumers be provided with relevant information and make a reasonable judgement in purchasing food. Fifth, it is necessary to provide detailed regulations and measures for concrete contents and directions of information on GMOs. Sixth, it is necessary to provid information on GMOs from the commercial sources of information that are most preferred by consumers.

The purpose of this paper is to setup reasonable criterion for underwriters to reimburse the expenses of suing and labouring incurred by assured, using game theory. As for the upper limit for the reimbursement, MIA and ICC do not mention at all but stipulate that proper and reasonable expenses shall be reimbursed, while ITC-Hulls set the amount insured as the upper limit to compensate the sum of expenses and damage loss. And as for failed measures of averting and minimizing loss, MIA and ICC do not mention either, while ITC-Hulls stipulates underwriters shall compensate the expenses and damage loss within the amount insured. The main results of this paper are as follows: First, it is for the benefit of underwriters to reimburse the expenses incurred to take such reasonable measures to avert or minimizing a loss which would be recoverable under the insurance. Second, the expenses of single measure should not be above the amount insured. Third, even if the measures failed, the expense should be reimbursed if it is less than the expected value of the subject-matter insured that could be recovered by the measures. Last, if the measures are taken several times individually, even if the sum of expenses might be above the amount insured, it should be reimbursed.

This paper treats the analytical and experimental studies on the improvement of commutating circuit for the speed control of DC motor. A simple circuit composed of R, L and C elements is proposed here for switching off power SCR carrying the load current. The real important in this chopper circuit is to determine the reasonable values of commutating circuit constants. In this paper, the reasonable values of the commutating circuit constants are basically determined on a view point of commutating performances in the given circuit model and must satisfy the following conditions. The first, the peak commutating current should be larger than the anticipated maximum load current. The second, the circuit turn-off time (tc) must be longer than the SCR turn-off time (tq). The third, the resistor should be enough large to permit the current to be neglected in the analysis of the commutation circuit, as well as be enough small to permit to charge the capacity voltage (Ec) to the half the value of source voltage (E) before the next communication cycle is initiated. The last, the period of chopping signal must be the least possible multiple of the damping vibration period of commutating circuit. The improved chopper circuit used in the experiment under unloaded condition was composed to meet the reasonable conditions mentioned above, and a successful commuting performance was achieved without failure. Several types of microprocessor having a different value of CPU speed individually have been applied to the experiment under the loaded conditions. Also it shows that the faster the speed of CPU is, the more stable the commutation turns out.

The aim of this study was to provide the reasonable data for design of the nozzle which produces finer droplets on the same level of the effective travel distance or which transports droplets to the farther target on the reasonable atomization in comparison with the commercial nozzles being used much in Korean rural areas. Newly designed twin-fluid atomizers with some commercial nozzles were tested in this study, and their results were as follows : 1. The characteristics of the spray deposit distribution of No.1 nozzles for farther target were nearly same in the near or nearer travel distance less than 8m. Therefore it was reasonable to combine the characteristics of the spray deposit distributions of No.2 and No.3 nozzles to those of No.1 nozzle. 2. The effective travel distance was increased with increase of the sectional area of the jet ligament, and the maximum effective travel distance was reached to about 17m. 3. The droplet size was increased with increase of the sectional area of the jet ligament, and the maximum droplet size was produced in the front of the point of the maximum spray deposit distribution. 4. The atomization was excellent in the twin-fluid atomizer in comparison with the hydraulic atomizer and also the effective travel distances were nearly same level in both atomizers.
