출연기관 감사업무 효율화 방안은 네가지 측면에서 정리하여 볼 수 있다. 첫째, 법률적 측면에서 보면 감사원법에서 출연금은 감사대상에 포함되어 있어 출연기관은 감사제도를 운영하게 되어있다. 둘째, 정책적 측면에서 국회에 의한 국정감사는 연 1 회 총 20일간에 걸쳐 수행되므로 시간적 제약과 함께 지속성, 일관성 있는 적절한 감사가 이루어지기 어려운 측면이 있다. 셋째, 행정적 측면에서의 필요성은 일반적으로 이공계 연구개발 업무를 수행하고 있는 과학기술부 산하의 출연연구소는 정부기관이나 지방자치단체 또는 보조금 지원 기관과는 그 성격이 완연히 다른 연구기관임으로 연구생산성 제고에 적합한, 기관 특설에 맞는 자체 규정의 보완이 필요하다. 마지막으로 사회문화적으로 감사업무는 능률우선주의보다는 서류체계 및 규제중심으로 편향되기 쉬운 특성이 있어 이에 대한 개선방안 노력이 매우 중요하다. 출연기관의 감사기능은 내부.외부감사에 의하여 수행되고 있으나, 감사(監査)의 핵심적 기능은 역시 출연기관 자체의 감사(監事)에 의하여 수행되며 성격상 공정성(Fairness), 객관성(Objectivity), 신뢰성(Reliability)의 확보가 필수적이다. 출연기관 감사제도의 개선방향은 합법성, 합목적성을 근거로 기관운영의 효율성을 제고시키는데 초점을 맞춘 감사제도로 개선되어야한다. 감사조직체계의 개선, 전문 교육의 실시, 동일업무의 기준 마련, 상급기관과의 역할분담 정립 등으로 감사업무의 질적수준 및 효율성을 제고해야 한다. 감사평가제도는 그동안 실시된 사항이 없으므로 긍정적인 측면과 부정적인 측면이 공존하므로 평가제도의 도입 및 적용에 대해서는 보다 심층적인 검토가 필요하다. $[$감사조직의 평가요소$]$ ■ 투입요소측면 - 감사인력 - 장비 및 고정자산 - 예산(년도별) - 정보수집관리 - 조직운영방식 -전통 및 관습 - 관계법령, 규정, 감사업무지침 ■ 산출요소측면 - 감사운영 실적 - 감사보고 실적 - 감사제도 개선 및 자체개혁 실적 - 기관운영 효율화 기여도 - 기관의 연구성과 및 업적 향상 기여도 - 경영관리 고도화 기여도 등의 항목설정이 가능 출연기관 감사업무의 효율화 방안으로 감사제도 개선의 기본방향, 감사조직 및 인력운영의 개선, 감사업무 운영체계의 개선 등을 중심으로 발전방향을 제시하였다. 그러나 여기에서 제시된 개선방안들을 추진하기 위해서는 전문인력을 보강하고 상부체계에서의 수용이 요구되므로 출연기관 권역에서만으로의 힘으로는 한계가 있을 것이며 무엇보다도 감사제도 변화의 필요성과 미래지향적인 환경이 조성되어야 할 것이다.

Consistent and realistic error covariance information is important for position estimation, error analysis, fault detection, and integer ambiguity resolution for differential GNSS. In designing a position domain carrier-smoothed-code filter where incremental carrier phases are used for time-propagation, formulation of consistent error covariance information is not easy due to being bounded and temporal correlation of propagation noises. To provide consistent and correct error covariance information, this paper proposes two recursive filter algorithms based on carrier-smoothed-code techniques: (a) the stepwise optimal position projection filter and (b) the stepwise unbiased position projection filter. A Monte-Carlo simulation result shows that the proposed filter algorithms actually generate consistent error covariance information and the neglection of carrier phase noise induces optimistic error covariance information. It is also shown that the stepwise unbiased position projection filter is attractive since its performance is good and its computational burden is moderate.

This study has two major purposes. First, this research empirically tests whether there are the impacts of the third-person effects on individuals' perceptions of the girl groups' suggestive performance. The second purpose of this study is to examine the relationships between the perceptual biased toward the influences of the girl groups's suggestive performances and the supports for regulation. For this purpose, this paper investigated individuals' perception of different degrees to which the suggestive performance has influences on three dissimilar groups including 'the self', 'colleagues' and 'the others' and how they affect supports for regulation. An online survey was administrated on 305 people who have watched the girl groups' lasciviousness performance for data gathering. The collected data were analyzed with t-test, multiple and hierarchical regression. The results showed that there are significant differences in perceptions of the effect of suggestive performance on three groups including 'the self', 'colleagues' and 'the others'. The findings also revealed that the perception of the effects of lasciviousness performance on 'the others' is one of the strongest predictors for the supports for regulation. The implications of these results were also discussed.

Relationship between the daily mortality and total suspended particulate(TSP) for the period of 1996-1997 was examined in Seoul, Korea. Generalized additive model was adapted for the analysis to allow the seasonality and long-term time effect in the air pollution and the nonlinear relationships with weather variables such as air temperature and relative humidity. An increase of 100 Ji9/m') TSP corresponds to 0.8-5.2 percent increase of the daily mortality Unidirectional (prospective and retrospective) case-crossover design results in large bias of the estimates. Bidirectional method gives relatively unbiased estimates but the standard errors are larger Case-crossover design should be used with caution in the situation where the data have seasonal trends like air pollution study.

This paper analyzes the discrimination of private property right protection in urban regeneration projects that is implemented by eminent domain based on public use in the United States. In spite of urban regeneration projects which depends on property condemnation for public use as a coercive power, it is executed on the discrimination of property right and sacrifice of the social disadvantages that transfer property from these private party to another big capitals and private developers. At first this paper investigates research trends in urban regeneration within the framework of multidisciplinary approach and suggests legal geographical perspective as a new research field. Next I figure out current state, types and numbers of brownfields site with the EPA and GAO data, and define these sites as results of deindustrialization and suburbanization process. Finally this paper uncover that the discrimination process of private property right is due to complex actions of expansion of public use concept in the U.S. Supreme Court from public ownership to economic public use, privatization of eminent domain, growth coalition regime and business friendly policy focused on economic development, class and racial bias, neoliberal movements of property right reform.

From the analyses of 16 bottom sediment samples and current data obtained during field expert ments from August to September 1987, the textural characteristics and transport mode of sand grains of a tidal sand ridge in Gyeonggi Bay are studied. The textural characteristic of the bottom sediments are diverse depending on their location on the tidal sand ridge. Sands on the crest are well sorted. near symmetric in skewness. leptokurtic in kurtosis. and are unimodal in peakedness. On the other hand, Poorly sorted gravelly sands in the trough are coarse skewed in skewness and plartkurtic in kurtosis. The mean values of U/SUB 100/ (velocity at one meter above bottom) and U/SUP */ (boundary shear velocity) are calculated to be 41.4 cm/sec and 2.39 cm/sec, respectively. From the analyses of characteristics of the sediments and currents in the study area, it can be concluded that almost all the sands of the tidal sand ridge (esp. on the crest) are transported as bedload (mainly as saltation).

In order to investigate the effect of second phase on $Al_2O_3$ matrix, SiC particles were dispersed in $Al_2O_3$ matrix as a second phase over the content range of 5 vol.% to 20 vol.%. To this mixture, $Y_2O_3$ or $TiO_2$ powders were added as a sintering additive before isostatically pressing and pressurelessly sintering at 180$0^{\circ}C$ for 90 min in $N_2$ atmosphere. With increasing SiC content, relative densities of composites were decreased but mechanical properties of composites were improvjed. In the case of adding $Y_2O_3$ as a sintering additive, maximum values of flexural strength, hardness and fracture toughness were 525 MPa, 17.1 GPa, 4.1 MPa.m1/2 respectively. In the case of adding X$TiO_2$ as a sintering additive, maximum values of flexural strength, hardness were 285 MPa, 12.1 GPa respectively. Improved mechanical properties were found to be the results of grain growth control of $Al_2O_3$ matrix and crack deflection by the second phase SiC particles.

Aging educational facility shall be managed and maintained through integrated service perspectives, in consideration of functions of each facility to provide safe and comfortable environment, rather than temporarily fixing/repairing problems. For doing this, it is a must to firstly understand the limitation of highly biased performance-based maintenance practice, which is a most common type applied at present, and therefore to establish maintenance system that reflects the functions and characteristics of maintenance service that a facility was designed with. Therefore, the objective of this study is to find items that have an influence on service level recognition in order to fairly evaluate service functions of educational facilities, and subsequently to use these factors as ingredients of establishing a consistent and efficient maintenance system. Therefore this study proposed explanatory variables to measure influential factors for each major maintenance category. Then appropriate statistical verification was carried out on questionnaires that collected from a number of industry experts to test its fe asibility.

The purpose of this study is to assess pre-service elementary teacher's conceptions of environmental issues. 141 pre-service elementary teachers from local college participated in this study. We discovered that most of participants understood the possibility of technological abuse that could lead to environmental destruction. They also well understood the crisis of the Earth's ecosystem. Nevertheless, it seemed most of participants were not ready to take action to save ti. In addition, they also showed stereo-typically biased opinions about science, technology and their relationship with environmental issues. It appeared to come from media-oriented environmental education. Since pre-service teacher's conceptions could directly effect future education, it is necessary to establish a more systematic educational system for environmental education, for both pre-service teachers and students.

In this study, the inlet duct and guide vane of the gas floating absorption tower were redesigned to improve the desulfurization efficiency so that the exhaust gas can be uniformly introduced into the absorption tower. In order to reduce the sulfur oxide pollutants among the main sources of air pollutants in industrial boilers, the existing equipment is redesigned and solved. For this purpose, change the exhaust gas, the slurry and recycling the adsorbent to improve the removal efficiency of SOx component in the exhaust gas inside the gas floating absorption tower so as to uniformly contact. And the initial design value and CFD value for the pressure loss from the boiler outlet to the gas floating absorption tower outlet are verified. Also, the velocity distribution of the exhaust gas, the concentration distribution of the recycled adsorbent, the liquid slurry behavior, and the pressure loss were compared. The results confirmed that the desulfurization efficiency was improved because the pressure loss from the boiler outlet to the absorption tower outlet was reduced and the deflection of the exhaust gas was minimized.
