정보화 사회로 발전이 되면서 고품질 소프트웨어에 대한 관심과 요구가 증대되고 있다. 이에 따라 소프트웨어 제품 품질을 평가 및 관리하는 활동이 개발 활동과 함께 중요시되고 있다. 또한, 소프트웨어는 관련되는 이해당사자 마다 품질을 바라보는 다양한 시각이 존재할 수 있으며, 개발의 각 단계에서 중점적으로 관리되어야 할 품질특성이 필요하게 된다. 이러한 다양한 관점과 수명주기의 특성을 고려한 품질특성의 중요도는 품질관리 활동을 보다 효과적으로 수행할 수 있게 해준다. 그러나 소프트웨어 품질의 중요도에 대한 연구는 그 필요성과 효과성이 제대로 부각되지 않아 많은 연구가 진행되지 않았다. 본 논문에서는 소프트웨어 제품 품질의 기준이 되는 ISO/IEC 9126을 기반으로 소프트웨어 수명주기에서 품질특성의 중요도를 결정하는 기법을 제시하고자 한다. 제안된 기법은 소프트웨어와 관련되는 주요 이해당사자들을 대상으로 한 설문조사와 AHP 기법을 이용한 중요도 분석을 통해 이루어진다. 이를 통하여 수명주기에서 중요도 우선순위에 의하여 품질특성을 선별할 수 있으며, 소프트웨어 품질을 정량적으로 측정하고 개발 완료 후의 소프트웨어의 품질을 예상할 수 있게 하여 고품질의 소프트웨어를 획득할 수 있게 한다. The concern and request of high-quality software has been increased according to the rapid transition of society to information-oriented era. Therefore activities of software quality management are regarded as serious as the activities of software development. Moreover, stakeholder of software may have various views of software quality. And some quality characteristics need to be managed with priorities in Software Development Life Cycle (SDLC). Hence we recognized that weights of quality characteristics might be useful to improve efficiency of quality management activities. However, this topic has not actively issued because its necessity and effectiveness has been ignored. This paper presents a technique to decide weights of software quality characteristics in SDLC. It is based on ISO/IEC 9126 which is the standard for software product quality. It is accomplished by questionnaires intended for stakeholder in software development and weight analysis through AHP (Analytic Hierarchical Process) method. Accordingly, it can select quality characteristics by weight in SDLC. And then it helps us to acquire high duality software through measuring software quality quantitatively and expecting the quality after completion of software development.

A three year project was carried out to determine the discharge of major nutrients from the agricultural land to the catchment basin during rice-season, i.e. May to October. The catchment area was 96.2ha, which was consisted of 12.5 ha for the paddy rice

Bovine viral diarrhea (BVD) is one of the problematic wasting diseases in cattle leading to huge economic losses. This study was conducted to investigate the prevalence of BVD including transient and persistent infection from cattle farms in Gyeongsangnam-do. A total of 2,667 blood samples from 24 farms were collected and the sera were subjected to ELISA to detect BVD virus (BVDV) antigen, E<sup>rns</sup>. 5' untranslated region (5'-UTR) of BVDV-positive samples was sequenced to identify the genotype, and compared with isolates previously reported elsewhere. There were fourteen BVDV-positive calves from 2,667 samples (positive rate: 0.52%) from first ELISA testing followed by eight persistently infected out of eleven BVDV-positive samples (72.73%) in secondary ELISA that was conducted in at least four weeks suggesting the circulation of BVDV in the area. Sequencing analysis exhibited that thirteen BVDV-positive samples were identified as BVDV-1b and one sample was BVDV-2a. Phylogenetic analysis revealed that the BVDV-1b-positive samples showed the highest homology in nucleotide sequence to Korean isolates collected from Sancheong, Gyeongsangnam-do, while the BVDV-2a-positive sample (21GN7) was more similar to reference strains collected outside South Korea. This study will provide the recent fundamental data on BVD prevalence in Gyeongsangnam-do to be referred in developing strategies to prevent BVDV in South Korea.
