In this study, we reviewed the definition of completeness and payment in SW appraisal along to being complicated requirements of the appraisal, and we also presented their meaning and computation method. The completeness in SW appraisals means the degree of functional completion of the final product, and the payment refers cost spent to develop the product. Therefore, the completeness is evaluated based on the functions or interfaces of the final product, while the payment is calculated on the outputs or expenses of development steps. Recently, SW appraisal is complicated and the requirements for completeness and payment are changing. In this paper, we review the meanings and objectives of completeness and payment and present the evaluation methods for those.

In this study, problems of software completeness appraisal are pointed out and their solutions are presented by analyzing appraisal cases and judicial precedents. Completeness appraisal, ready-made appraisal, defect appraisal, and cost appraisal have been classified as and have been evaluated with extant software completeness appraisals. From a legal point of view, and in judicial precedents, however, there is a big difference between the definition of completeness and the completion rate. This is because the degree of completeness is evaluated under the premise that the software's development is complete, whereas the ready-made appraisal inspects the development progress of unfinished software. Often, in cases involving software completion rate, the total completion level is calculated by weighting each step of the software development process. However, completeness evaluations use the software's realization-operation as its sole criterion. In addition, another issue not addressed in existing software completeness appraisal cases is that there is no mention of who is responsible for software defects, whereas in case law, the responsible party is determined by finding who caused the dispute. In this paper, we systematically classify these problems, and present a novel evaluation method that separates software completeness evaluations from software completion evaluations.

In domestic public works, there are several problems in the measurement of payments based on the bill of quantity, which doesn't match with the activity progress rate, heavy paper works and complicated procedures. It can be classified formal and simplified method. By using the simplified method, it can be solved many problems by summarizing the procedure, but is not generally used. This paper proposes a payment method by progress measurement for specified activity based on WBS(Work Breakdown Structure) verifying efficiency which reduced cost account and advanced work on payment compare to method of domestic public works using the data about construction of eco-river. This method will be an important contribution on being a base for cost-schedule integrated management which were verified and also improving efficiency on measuring payment.

고준위 방사성 액체폐기물에서 얻어지는 백금족 금속(Pd, Rh, Ru) 들의 분리 및 정제방법으로 강염기성 음이온교환수지를 사용하여본 결과 상용 수지중에서 Dowex 1 $\times$ 8 이 IRN-78 에 비하여 저 농도의 질산 농도에서 Pd(II) 의 분리 및 정제시 우수한 흡착성을 보여 주었으며 Rh(III) 의 흡착은 Pd(II) 의 것보다 훨씬 낮은 값을 보여 주었다. 이 수지들의 백금족 금속에 대한 흡착성을 문헌에 보고된 실험 결과들과 비교 검토하여 본 바 이온 그룹으로 3급 및 4급 Benzimidazole을 가지는 수지에 비하여 훨씬 낮은 값을 나타내었다. 따라서 실용성이 큰 강염기성 음이온수지로서는 Benzimidazole과 같은 혼합 아민 그룹을 지닌 수지가 가장 접합할 것으로 전망되었다.

Large-scale simulated lysimeter experiments were conducted for 4 years as a fundamental study to develop enhanced landfill stabilization method, which accelerate stabilization time and make efficient practical use of self-purification capacity of pollutants in semi-aerobic solid waste landfill. The amount of TOC(total organic carbon) decomposition increased as the landfill depth increased. In case of T-N(total nitrogen), the self-purification capacity increased linearly with the landfill thickness until it reached a maximum level of 6 m. Beyond this level, the self-purification capacity was not increased. The results from lysimeter experiments indicate that 6m of landfill thickness is optimum for self-purification capacity of pollutants considering the mass balance of TOC and T-N.

S/W 개발 프로젝트의 품질, 비용, 개발 기간을 잘 관리하여 프로젝트를 성공시키기 위해 PM 은 프로젝트의 종료시점과 예산의 초과를 예측할 수 있어야 한다. PMBOK 의 비용관리의 Earned Value Method 는 프로젝트의 진행에 따른 생산성의 변화와 그에 따른 비용과 일정의 증가 추정에 대한 규칙을 제시한다. 그러나 EVM 은 제조공정에서는 그 효과를 증명하였지만, S/W 프로젝트에서는 적용이 힘들어 잘 활용되고 있지 않다. 이는 사람이 주요 자원인 S/W 프로젝트에서는 Actual Cost 의 측정이 쉽지 않기 때문이다. 따라서 본 논문에서는 S/W 프로젝트 관리에서 Earned Value 의 측정이 쉽지 않아 추정되기 힘든 지연된 종료 시점에 대한 예측을 PMBOK 과 CMMI 에서 제시하는 관리 영역과의 연관성을 활용하고, EVM 을 보완하여 지연에 대한 예측모델을 만들어보고자 한다.

Rock-surface temperatures were observed at a trachytic lava dome, called as Baeknokdam Northwest Face, in the summit area of Mt. Halla, Jeju Island, to examine the frequency and occurrence season of freeze-thaw cycles and the rate of temperature changes during a freezing period. Long-term measurements were recorded over 18 months from November 2006 to April 2008, at a 1-hour logging interval and rock depth of 1.5 cm. Both diurnal freeze-thaw cycles and effective freeze-thaw cycles appear in larger numbers on a south-facing rock face than a north-facing rock face. The diurnal cycles were dominantly observed on February and March for the south face and on November and April for the north face, respectively. The annual freeze-thaw cycles were confirmed in terms of the presence of seasonal freezing periods lasting from mid-November to mid-April for the south face and from early-November to late-April for the north face, respectively. The rate of decreasing temperatures during the seasonal freezing periods is larger on the north face than the south face. Notwithstanding the lower numbers of freeze-thaw events, the north face experiences a higher frost intensity since the number of hours below $-3^{\circ}C$ is larger on the north face than the south face. The number of freeze-thaw events and the duration of days with continuous sub-zero rock temperatures largely depend on the solar radiation controlled by the aspect of the monitored rock surfaces, and thus the high-frequency short-term frost cycle dominantly appears on the south face and the annual frost cycle on the north face, respectively.
