기술이 고도화, 다양화되면서 소프트웨어의 발전이 급격하게 이루어지고 있다. 이에 따라 소프트웨어 GUI (Graphical User Interface)의 사용성(Usability)에 대한 연구가 활발하게 진행 중이다. 그럼에도 불구하고 무기체계 소프트웨어는 GUI의 사용성에 대한 연구가 부족한 실정이다. 이에 본 논문에서는 무기체계 소프트웨어 GUI에 대한 사용성 평가 항목을 도출하고 설계 우선순위를 도출하였다. 사용성 평가 항목을 도출하기 위해 전문가 평가를 통해 사용성 평가에 대한 기준요소 (Attributes)와 설계요소(Design factors)를 선정하였다. 또한 AHP(Analytical Hierarchy Process)와 매트릭스(matrix) 분석을 이 용하여 각각 기준요소의 상대적 중요도와 기준요소와 설계요소간 연관성을 파악하여 최종적으로 설계 우선순위를 도출하였 다. 그 결과, 정보제공성(Informativity)과 정보접근성(Accessibility), 가시성(Visibility)의 중요도가 0.127, 0.121, 0.108로 도출 됨에 따라 기타 요소에 비해 우선적으로 평가하는 것이 바람직할 것으로 판단된다. 본 연구는 무기체계 소프트웨어 GUI의 사용성 평가에 대한 기반 연구로 활용될 수 있을 것이다. With the technology of our time growing sophisticated everyday, softwares advance rapidly in accordance. Reflecting this trend, researches on Usability of S/W GUI(Graphical User Interface) is actively taking place. However, despite the active researches on such topic, Usability study of S/W GUI for weapon system remains insufficient. For such reason, this paper intends to focus on drawing evaluation factors as well as priority of design factors for Usability of S/W GUI for weapon system. For an accurate and reliable result, Usability evaluation attributes & design factors were assessed by professionals. Moreover, by incorporating AHP(Analytical Hierarchy Process) and Matrix analysis, each evaluation attributes' level of importance and relation between design factors & usability attributes were assessed to draw final design priority. As a result, the importance of Informativity, Accessibility, and Visibility were derived as 0.127, 0.121, 0.108, and selected to be the foremost priority for evaluating. This research could be utilized as foundation for usability evaluation of S/W GUI on weapon system.

석가공폐수 처리는 처리 과정에서 약품응집제를 사용하고 있기 때문에 환경오염 및 생태계의 변화에 많은 문제점을 유발하고 있다. 본 연구에서는 경사분리기를 개발 제작하여, 석가공폐수처리에 대한 처리특성을 규명하고자 COD, SS, 탁도를 분석하였으며, 실험결과는 유입수량 0.3 ㎖/sec의 경우 회전속도 3500rpm에서 COD제거효율 86.92%~90.54%, SS제거효율 97.56%~98.53%이었고, 유입수량 0.4㎖/sec의 경우 회전속도 3500rpm에서 COD제거율효율 83.11%~89.46%, SS제거효율 96.33%~97.07%를 나타내었다. 탁도는 유출수에서 220~350NTU, 제거효율 98.24%~99.11%로 나타냈다. The present treatment system of stone wastewater cause various environmental pollutions in ecosystem due to the fact that it uses chemical coagulants in the treatment process. In this paper, we developed and manufactured the decanter and then analysed the removal retes of COD, SS and turbidity to reveal the treatment characters according to stone wastewater treatment. As a result experiment showed COD removal rete was 86.92%~ 90.54% and SS 97.56%~98.53% when the feed velocity was 0.3㎖/sec and rotational speed Was 3500rpm. On the other hand, It showed COD removal rate is 83.11%~89.46% and SS 96.33%~97.07% when the feed velocity was 0.4㎖/sec and rotational speed 3500rpm. Turbidity showed 220~350NTU, removal rate was 98.24%~99.11% in effluent water.

Process intensification without any increase in bed requires the exploitation of fluid mechanical phenomena as the basis for elegant solutions to the process engineering problems which result from the need to retain and control the immobilized biomass, and for biomass recovery. The fluidized bed bilogical reactor provides a solution to these needs. The wastewater treatment characteristics of the fluidized bed was filled with asnd media. Indirect aeration were studied experimentally. The optimal range of velocities was 1.17㎝/sec∼1.32㎝/sec, and under the BOD loading condition of 4.5㎏-BOD_5/m^3·d, the media concentration appeared to 18% and surface upflow velocity also 1.32㎝/sec for the maximum BOD removal. The media effluent unfiltered BOD_5 was 92%∼94%, at an HRT of 32 mintes.

Spin machines, used to remove a component from a multiphase mixture, may be among the earliest used in human evolution. When environmental engineers realized the possible use of the centrifuge in the field of sludge treatment, centrifuges had already reached an advanced stage of development. Solids migrated through the liquid radially to the bowl wall by centrifugal forces. The bowl could rotate with an elevated speed up to 1000rpm. The removal of the very fine particles form the liquid requires comparatively high acceleration numbers of the centrifuge when flocculants are not used. The recovery, based on the solids content in the liquid may be between 80 and 97%.
