산지토사재해 발생시기 예측정도를 높이기 위해 사용되고 있는 산지토사재해 기준우량 산정방법에 대해 수문모형인 Tank 모델의 적용수법을 개발하였다. 개발된 방법과 저류관수법에 의한 결과의 비교 검토로 향후 적용가능성도 검토하였다. 산사태 발생시기 기록이 있는 36개의 산사태를 대상으로 저류관수법과 개발된 Tank 모델에 의한 방법을 적용하여 재해발생시기와 최대저류량과의 관계를 검토한 결과, 퇴적암 4기의 경우 Tank 모델에 의한 산사태 발생 예측시기는 1.6시간의 차이를 보였으나, 저류관수법에서는 3.2시간 차이를 보였다. 또한, 최대저류량의 편차가 Tank 모델의 경우 7%에 불과하나, 저류관수법의 경우 63%의 큰 편차를 보였다. 산사태 발생강우를 대상으로 최대저류량 값들 중 가장 작은 값을 위험기준우량으로 설정하여 대상지역의 5년간(1993~1997) 실제 강우량을 적용한 결과, Tank 모델에 의한 피난대기시간이 저류관수법보다 약 2배 작은 것으로 나타났다. 따라서, 본 연구에서 개발된 Tank 모델에 의한 산지토사재해 위험기준우량 산정이 저류관수법보다 정도 및 실용적인 측면에서도 우수하여 향후 충분히 활용 가능한 방법으로 판단되었다.

N-Screen 환경에서 HTML5 표준 기반 콘텐츠 개발은 필연적이다. 그러나 높은 개발 비용과 개발 인프라 부족 등의 이유로 HTML5 조작형 콘텐츠 개발은 소극적이다. 이에 동영상, 오디오와 같은 멀티미디어 콘텐츠를 동적 조작 구현이 가능한 HTML5와 융합하여 사용자와 상호작용이 가능한 효율적인 콘텐츠 개발 모형을 제안하고자 한다. 제안 모형은 통합 제어용 플레이어를 포함한 HTML5 레이아웃 내에 멀티미디어와 iframe(inline frame) 영역을 구분 배치하도록 설계하였다. 상호작용형 HTML5 문서들은 화면 단위로 나누어 작성하여 iframe을 통하여 제공된다.

To effectively implement the integrated water management policy outlined in the National Water Management Act, it is essential to analyze agricultural water supply and demand at both basin and water district levels. Currently, agricultural water is primarily distributed through open canal systems and controlled by floodgates, yet the utilization-to-supply ratio remains at a mere 48%. In the case of agricultural water, when analyzing water balance through existing national basin water resource models (K-WEAP, K-MODISM), distortion of supply and regression occurs due to calculation of regression rate based on the concept of net water consumption. In addition, by simplifying the complex and diverse agricultural water supply system within the basin into a single virtual reservoir, it is difficult to analyze the surplus or shortage of agricultural water for each field within the basin. There are limitations in reflecting the characteristics and actual sites of rural water areas, such as inconsistencies with river and reservoir supply priority sites. This study focuses on the development of a model aimed at improving the deficiencies of current water balance analysis methods. The developed model aims to provide standardized water balance analysis nationwide, with initial application to the Anseo standard watershed. Utilizing data from 32 facilities within the standard watershed, the study conducted water balance analysis through watershed linkage, highlighting differences and improvements compared to existing methods.

In this research, the feasibility of non-destructive measurement technique of pungency measurement was investigated for the red-pepper powders produced in different domestic areas in South Korea. The near-infrared absorption spectra in the range of 1100 nm~2300 nm was used to measure capsaicinoids content in red-pepper powders by using a NIR spectroscopy equipped with Acousto-optic tunable filters (AOTF). Fourth three different red-pepper powders from 14 different locations were collected and separated in three different particle size (below 0.425 mm, 0.425~0.71 mm, 0.71~1.4 mm) for the spectral measurements. The partial least square regression (PLSR) models to predict the capsaicinoids content depends on particle size were developed with the measured spectra. The determinant coefficients and standard errors of the developed models for the red-pepper powders of below 0.425 mm, 0.425~0.71 mm, and 0.71~1.4 mm were in the range of 0.859~0.887 and 12.90~12.99 mg/100 g, respectively. The PLS model with the pretreatment of Standard Normal Variate (SNV) for the red-pepper powders below 1.4 mm particle size showed the best performance with the determinant coefficient of 0.844 and the standard error of 14.63 mg/100 g.

This study was to quantitatively evaluate periodic and maximum energy loads for broiler-standard design models by the Ministry of Agriculture, Food and Rural Affairs (2016). Building energy simulation method was used to compute heating and cooling loads of the designed broiler houses according to regional locations and insulation characteristics of wall and roof. It considered sensible and latent heat generation from broilers, dynamic operation of ventilation system according to environment variations. It was found that variation of periodic heating loads was relatively higher than that of periodic cooling loads according to thickness changes of wall and roof. Assuming that broiler was raised at every even-month, periodic heating and cooling loads were 6 and 18% lower, respectively than odd-month raising condition. When recommendation rules of insulation characteristics (wall and roof thickness) by the Ministry of Land, Infrastructure and Transport was adopted, periodic heating load of Jeju-si was 20.3% higher than national average values. Based on the BES computed periodic and maximum energy loads under the designed experimental condition, these results can contribute to reestablishing standard design of broiler houses, especially for insulation characteristics, and designing management strategies for efficient energy uses.

인공지능 소프트웨어 시장은 2020년부터 2025년까지 6배 규모로 성장할 것으로 예상된다. 그러나 소프트웨어의 개발 절차가 표준화 되어 있지 않고 비용 산정 기준이 없다. 이에 따라 인공지능 소프트웨어 개발 업체마다 각자의 개발 절차에 따른 투입 공수를 산정하고 이를 개발비용의 근거로 제시하고 있으나 개발업체마다 상이한 개발 절차와 소요 공수의 규모 때문에 품질과 비용에 대한 불신이 커지고 있다. 본 연구에서는 대량의 데이터로 학습을 진행하고 알고리즘을 도출하여 적용하는 인공지능 기반 소프트웨어의 개발단계를 정의하고 개발업체들을 대상으로 개발단계별 소요 공수에 대한 설문을 진행하여 소요 공수를 수집하였다. 수집된 개발단계별 소요 공수간의 상관분석과 회귀분석을 실시하여 개발단계별 소요 공수 예측 모형을 도출하였으며, 모형을 실험한 결과, 수집된 소요 공수 대비 92%의 정확도를 보였다. 본 연구에서 제안한 소요 공수 예측 모형은 공수와 비용을 추정하는데 간단하게 활용할 수 있는 도구가 될 것으로 기대된다.

Requirements management is one of the most essential activities of systems engineering in developing successful weapon systems. Particularly it is very important to consistently manage the traceability among the user requirements, the system requirements, the development specifications and the testing plans throughout the entire life cycle of the weapon system. However, the most part of requirements-related activities has centered around the functional and performance requirements but the integrated logistics support(ILS) requirement has not properly been managed. In this regard, a special attention is needed to develop and manage the ILS requirements. To do so, the ANSI/EIA-632 standard can be referred as a starting point since the ILS requirements of the weapon system under development are specified by the enabling products whereas the functional and performance requirements are covered by the end product requirements. Specifically, we first review and model several cases of previous weapon systems development, which reveals the problem of interest. Then, under the framework of ANSI/EIA-632, we study a hierarchical model for effectively managing ILS requirements by analyzing the features of ILS requirements. Finally, the value of the proposed model is discussed through the case study of electronic warfare equipment.

Since IT technology was combined with the power system, many systems and applications have been developed and also Integration between systems has been followed in order to meet much higher level. Futher more to reduce the cost of system integration there were needs standardized data model and interfaces among systems or applications. so IEC has reached to establish standard interfaces and data model. Most of the current distribution automation system in South Korea, each operating independently in an enclosed environment, are managed. As time goes by, however, because of resons that the system is increasingly complex by implenting new kind of power source and demand for electricity is rapidly increasing, it became difficult to predict with a independent data from one system. In this paper, In order to apply common infomation model and standard interfaces which are defined in IEC 61970/61968 to the exisiting distribution automation system in KEPCO, several software tools and applications which have been created will be introduced.
