  • 기술 중심의 ESCO 전문화를 위한 전문 ESCO 지정제 평가기준 마련이 요청되어 왔다. 이에, 본 연구는 전문 ESCO 지정제도에 관한 평가기준을 설정하기 위해 5가지 목적을 전제하였다. 즉, 에너지 절감의 우수성, 경영지표의 건전성, 고객만족도, 원천기술 보유업체의 참여 유도, 절약성과 보증계약 중시 등이다. 이를 바탕으로 전문가 자문을 통해 전문 ESCO 지정을 위한 평가배점(안)을 전문성(40점), 경영상태(15점), 고객만족도(20점), 기술능력(25점) 등 평가지표로 구성하고, 각각 세부 평가항목의 선정 및 배점기준을 설정하였다. ESCO 업계 설문조사를 통해 비교적 높은 동의율을 보였다. 전문 ESCO 지정제도의 적용 시 기업규모를 중소기업으로 한정하고 적용기술 대상을 조명, 열병합발전, 공정개선, 폐열회수, 냉 난방설비 등 5개의 특정 기술분야로 지정하는 것이 가능할 것이다.

  • As number of cyber traders are growing, the uses of technical analyzing indicators in trading increase as well. Parabolic SAR, which indicates changes of trend in the market, is one of the most used indicators by cyber traders. Especially when a market shows a specific trend, it is very useful. However, this indicator often gives late signals and shows less trustful ones in a stable market. This paper proposes a method that give more conservative signals by a composition of Parabolic SAR and Moving Average. The experiment will compare the earning rates of using only Parabolic SAR strategy and of using a composition strategy of Parabolic SAR and Moving Average.

  • It is well known that certain classes of dye are reducible to stable colorless leuco compounds, which can be oxidized in air back to the colored species. We now reported that bis(4-dialkylaminophenyl)squaraine dyes are readily reduced in solution by borohydride to give alkali soluble leuco compound, which exists in the 3-hydroxy 2,4-bis(4-dialkylaminophenyl)cyclobuten-one. New alkylamine leuco compounds were synthesized by the reaction of leuco chloro-squaraine with alkylamine derivatives. The leuco compounds are easily isolated and can be air oxidized back to the squaraine dyes. These dyes have many technical application. e.g. in xerography, solar cell, optical recording material, redox indicators, and enzyme assays.

  • 주가지수는 한 국가의 경제 지표뿐만 아니라 투자판단의 지표로도 활용되므로 이를 예측하는 연구가 지속해서 진행되고 있다. 주가지수 예측을 하는 작업은 기술적, 경제적 및 심리적 요인 등이 반영된 것으로 예측의 정확도를 위해서는 복합적 요인을 고려해야 한다. 따라서 지수의 변동에 영향을 미치는 요인들을 선별하여 반영한 주가지수 예측모델연구가 필요하다. 이와 관련한 기존 연구에서는 시장의 변동을 만들어 내는 뉴스 정보 또는 거시 경제 지표를 각각 이용하거나, 몇 가지의 지표 조합만을 반영한 예측 연구가 대부분이었다. 따라서 본 연구에서는 미국 다우존스지수 예측을 위해 뉴스 정보의 감성 분석과 다양한 거시경제지표를 고려하여 효과적인 지표 조합을 제시하고자 한다. 뉴스 정보의 감성 분석은 최신 자연어처리 기법인 BERT와 NLTK VADER를 사용하고, 예측모델은 주가예측모델로 적합하다고 알려진 딥러닝 예측모델 LSTM을 적용하여 가장 효과적인 지표 조합을 제시했다.

  • In order to apply a water quality indicator as a certain target pollutant, the indicator should have the representability of an index for the management of Total Maximum Daily Loads (TMDLs). Scientific groundwork and treatment technologies also should be provided for the application of the indicator. This study analyzed the applicability of major water quality indicators for target pollutants. The results showed that four water quality indicators of TOC, T-N, SS & T-Coli can be considered as target pollutants besides existing BOD and T-P. These indicators can be applied with the preparations such as essential basic data, pollution load estimation framework as well as legal criteria setting when the need is raised. As the importance of TOC, which is considered as a replacement of BOD, is emphasized, technical and institutional terms are being prepared in order to determine TOC as another target pollutant in the near future. It could be considered to combine TOC with BOD for the time being during the $3^{rd}$ stage of TMDLs in view of the present conditions for the management of TOC. TOC can be the most effective index for the organic matter and help to be managed more systematically in the waterbodies where rivers and lakes are mutually connected.

  • The modernization approach to monitoring regional processes of providing social services is proposed. The methodological approach is developed in the context of the modern public policy, which includes the following stages: the formation of a system of indicators that characterize the level of the social services modernization; the determination of the levels of regions development by such components as the modernization level of the economic sphere, the modernization level of the demographic component and the modernization level of employment; the determination of weights for each group of indicators and calculation of integrated indicators, ranking of regions; the allocation of criteria for classification and grouping of regions according to the modernization level of the social services sphere; highlighting the most important problems of each region. The proposed method is tested on the example of the Ukraine's regions. According to the results of calculations of the modernization level of the processes of providing social services, the ranking and grouping of the regions was carried out. The rating allowed to distinguish four groups of regions: regions with a high modernization level of social services, regions with above-average levels, as well as regions with medium and low levels. The author's modernization approach to monitoring the processes of providing social services allows to investigate the real state of the main indicators influencing these processes and to identify problem regions in order to develop mechanisms to stimulate their development.

  • 제4차 산업혁명의 핵심기술인 사물인터넷기술의 발달로 인하여 다양한 서비스가 가능하게 되고, 그 과정에서 개인정보가 자유롭게 처리되게 되었다. 그러나 스마트기기를 비롯한 정보기기가 네트워크로 연결되면서 편리한 서비스가 제공될수록 개인정보 침해위협도 증가하고 있는 실정이다. 따라서, 본 연구는 다양한 사물인터넷서비스를 구현함에 있어서 안전한 환경을 구축하고, 그 가운데 유통되는 개인정보를 보호하기 위해 필요한 정책선정을 위한 중요도에 따른 우선순위를 분석하여 주요정책과제로 제언하고자 한다. 본 연구에서는 문헌조사를 바탕으로 개인정보보호정책지표들을 전문가대상의 델파이분석을 통해 3개 분야 9개 영역 25개 지표로 구성하였다. 이러한 개인정보보호정책지표들은 AHP기법의 설문조사로 66명 전문가들이 응답한 결과를 활용하여, 정책지표의 상대적 중요도 및 우선순위를 도출하였다. 그 결과, 개인정보보호정책분야에서는 정책적 분야, 기술적 분야, 관리적 분야 순으로 상대적 중요도 및 우선순위가 도출되었다. 또한, 정책적 분야를 구성하는 3개 영역 중에서는 IoT관련 개인정보보호법제도의 강화가 가장 중요하며, 정책지표 중에서는 IoT에서의 개인정보보호법률의 제 개정을 추진하는 것이 가장 중요하다고 응답하였다. 또한, 조사된 IoT개인정보보호정책의 분야 영역 지표에 대해 쌍대비교한 결과값은 일관성을 갖고 있었다. 이렇게 도출된 개인정보보호정책지표들은 앞으로 안전한 사물인터넷 정책을 추진하여 국가경쟁력을 이끄는데 기여하리라 본다.

  • Four technical grade organophosphate pesticides (Fenitrothion, Fenthion, Dizninon and EPN) were investigated for their effects on the murine immune function. Among the immunotoxicological assay parameters of NIEHS, humoral immune parameter and pathotoxicological indicators were examined in this study. Subchronic exposure of rodents to these pesticides resulted in marked suppression of humoral immune function and moderate histological changes of lymphoid organ any significant alterations of clinical status.

  • The aim of this study is to design an intelligent pattern-based real-time trading system (PRTS) using rough set analysis of technical indicators, dynamic time warping (DTW), and genetic algorithm in stock futures market. Rough set is well known as a data-mining tool for extracting trading rules from huge data sets such as real-time data sets, and a technical indicator is used for the construction of the data sets. To measure similarity of patterns, DTW is used over a given period. Through an empirical study, we identify the ideal performances that were profitable in various market conditions.

  • In-situ stabilization is a remediation method using amendments to reduce contaminant availability in contaminated soil. We tested the effects of two amendments (furnace slag and red mud) on the availability of toxic trace elements (TTEs) and soil enzyme activities (dehydrogenase, phosphatase, and urease). The application of amendments significantly decreased the availability of TTEs in soil (p < 0.05). The decreased availability of TTE content in soils was accompanied by increased soil enzyme activities. We found significant negative relationships between the TTE content assessed using Ca(NO3)2-, TCLP, and PBET extraction methods and soil enzyme activities (p < 0.01). Soil enzyme activities responded sensitively to changes in the soil environment (pH, EC, and availability of TTEs). It could be concluded that soil enzyme activities could be used as bioindicators or ecological indicators for soil quality and health in environmental soil monitoring owing to their high sensitivity to changes in soil.
