많은 불확실성 항목들은 소프트웨어 실행 시에 존재한다. 특히, 유사한 분야에서 전반적인 시스템에 많은 영향을 주게 된다. 불확실성 요소와 같은 모호성 요소의 관리는 소프트웨어 신뢰성을 위하여 중요한 요소가 된다. 따라서 모호성을 식별하여 불확실성 요소를 제거하도록 판단기준을 프로세스화 하였다. 또한 본 연구에서는 소프트웨어 개발 시, 모호성을 제거하기 위한 불확실성 식별 기준과 불확실성 처리 프로세스 및 정량적인 평가에 대하여 제시한다.

Recently, the number of hornet is rapidly increasing because of change in the ecological climate. It gives a sense of threat to the people and damages the beekeeping industry as a predator of honey bees. Firefighters are working to remove hornet and vespiary, but it has been reported that it is difficult to remove at high altitudes. In this study, an ultra-light flying device was developed to remove vespiary. It has been developed in four types: Drug spray type, Clamp type, Cutter type, and Scraper type, which can be used as field-customized equipment. Therefore, the developed equipment is expected to contribute to the safe field activities of firefighters.

This paper presents a software reliability model that is based on a nonhomogeneous poisson process. The major contribution of this model is combining multiple failure types with imperfect debugging by use of S-shaped mean value function. The software reliability model allows for three different types of errors: Critical errors are the most difficult to detect and the most expensive to remove. Major errors are moderately difficult to detect and fairly expensive to remove. Minor errors are easy to detect and inexpensive to remove. The model also allows for the introduction of any of these types of errors during the removal of an error. A numerical example is provided to illustrate the above techniques.

Analog cassette tapes are easily changed due to environmental factors. To digitize is the best way to preserve a sound source. The way to digitize is to deal with the original sound to be enhanced to a variety of sources by playing through the audio card after recording. In this process to occur, it's the most important to remove various noise and equalizing sound in a method for preserving. It's studied about how to remove noise by using one of softwares, Cubase 5. 5, to remove hiss noise, which happens changing analog tape into digitalization. A amount of hiss noise is reduced to use X-Noise software of Wave which uses in Cubase 5.0, one of PLUG-IN. The noise is removed changing value of threshold and reduction every 10 times in no change of origin sound. To keep regular condition, the experiment to remove the hiss noise is conducted based on sound meondle, which is one of sound Nonmaegi. The noise is removed easily when the value of threshold is getting high in spite of giving a little value of reduction. However, as it gives a amount of reduction high, the damage rate of the sound source gets high.

The kidneys are exposed to toxicants and waste product and can be affected easily by these toxicants and by products of the metabolism. The consumption of adequate water is necessary to remove waste and to keep kidney healthy. Deficiency of liquid in the blood leads to various adverse effects on the kidney. The most common adverse deficiency of liquid in blood is deposition of solid matter in the kidney and subsequently formation of kidney stone. Nephrolithiasis (kidney stone) can be treated by drugs if it is small in size but if it blocks the route due to its big size then surgery is the only way to remove it. The recurrence rate of the problem is very high and it may reappear within 10 years. In Unani literature Hasāh wa Raml al-Kulya (nephrolithiasis) is described in detail. As per Unani literature stagnation of Ghalīz mādda (filthy and viscous matter) in the kidney is the main cause of the formation of kidney stone. Various single and compound formulations drugs are described for the management of kidney stone which are very effective as well as safe. Management is divided into two parts i.e. symptomatic treatment to relieve pain and to methods adopted to remove stone from the kidney. Musakkin-i-Waja'(analgesic) drugs are used for pain while Mufattit-i-Hasāh (lithotriptic) and Mudirr-i-Bawl (Diuretic) drugs are used to remove stone. Majoon Aqrab, Qurs Kaknaj and Dawa-e-Gurda etc. are compound drugs mentioned in literature for removal of kidney stone. Single drugs like Alu Balu, Tukhm Khayar, and Kharkhask etc. are also used for same purpose.

Urban land consolidation, which is to reform land parcels to remove fragmentation and produce ideal blocks, is an effective means for urban renewal. Successful urban land consolidation brings out great benefits to the city officials as well as general public, such as improved city image, increased land value, and more effective land use. However, urban land consolidation can be detrimental to environment, especially in the ecological aspects, while the execution of land consolidation has been focused solely on development for the sake of human benefits. To remove negative effects of urban land consolidation to the ecological system, this paper is intended to establish a set of criteria for evaluating ecological impacts of an urban land consolidation plan. Firstly, key ecological indicators are identified using a special group decision-making process called "habitual domain analysis" and then individual weighting of each indicator is recorded by analytical hierarchy process. An urban ecological evaluation model with 4 levels and 23 indicators is thus developed.

The impulse noise is very common and typical noise in the digital image. Many methods are invented in order to remove the impulse noise since the development of Digital Image Processing. For example, the median filter has been used for removing the impulse noise. In this paper, we try to remove the impulse noise using wavelet transformation in the wavelet-transformed detail areas. We also compare the algorithm with median filter with the visual and numerical methods. The result using the algorithm in this paper was much better than the median filter in both removing the noise and keeping the edges. The proposed algorithm needs more calculating time but has more advantages than the median filter has.

In this study the real situation of apartment house in seoul is reproduced with multi-zone modeling program contam2.4. This model include immune building system(disinfection system) which is consist of dilution, Filter Technology and UVGI(ultra violet germicidal irrdiation). In this study experiments design method used for estimating interaction of HRV air change rate, UVGI air change rate and UVGI grade. Result show that HRV air change rate and UVGI air change rate is most influence factor for remove rate. also Interaction of HRV air change rate and UVGI air change rate is ost influence factor for remove rate.

소프트웨어 규모가 대형화 됨에 따라 개발에 소요되는 시간과 인력도 대형화 되고 있으며, 또한 원하는 수준의 소프트웨어 품질을 얻기 위해 필요한 테스트 비용도 점점 더 증가하고 있다. 소프트웨어 프로젝트 개발 과정에서 품질 관리를 위해 다양한 결함 제거 기법들이 사용되고 있으나, 이러한 결함제거 기법과 결함 제거 시간이 전체 일정에 미치는 영향은 아직까지 체계적으로 분석되지 못하고 있다. 본 논문에서는 일정한 소프트웨어 품질 수준을 달성하기 위해 소요되는 시간을 소프트웨어 개발 일정 관리에 반영한 새로운 일정관리 모델을 제안한다. 제안된 모델은 CMU의 PSP/TSP (Personal Software Process/Team Software Process)를 적용하는 개발 과정에서 수집된 결함 정보, 결함 제거 시간, 평균 결함 제거시간 및 단계별 결함 제거율을 사용하여 일정 지연 여부를 실시간으로 추적할 수 있도록 하고 있다. 이를 위해 본 논문에서는 소프트웨어 품질 달성에 필요한 작업량을 일정 관리 측정체계와 동일한 측정체계에서 사용할 수 있도록 하는 품질 지수(Quality Value)를 새로 제안한다. 본 연구의 결과는 일정과 품질을 분리하여 관리하는 기존의 일정 관리 방법을 보완하여 프로젝트 관리자를 비롯한 모든 관계자가 품질 관리의 중요성을 인식하고 품질 저하 문제를 사전에 예방하는데 활용될 수 있을 것으로 기대된다.
