The purpose of this research paper is: (1) to describe the service quality index; (2) describe the data quality index; and (3) describe the anti-corruption index of BPS Trenggalek, Indonesia. The approach chosen is quantitative with the type of survey research. The primary data collection technique was mainly based on a questionnaire distributed to 40 respondents, namely BPS service users in 5 (five) categories: the private sector, the banking industry, academics, offices, or agencies in Trenggalek Regency and universities. The results showed that the quality of BPS services was good and the data quality index where the respondents were satisfied with the data presented by BPS. Meanwhile, testing the anti-corruption index shows that BPS Trenggalek is very anti-corruption in providing services to consumers. The findings of this study suggested that to improve service quality, it is necessary to pay attention to several aspects, including published service requirements, easy requirements to be fulfilled, published procedure information, clear service process flow, published service times, and costs/tariffs are communicated. This study suggests updating data, data relevance, data accessibility, and data completeness to improve data quality. Furthermore, to maintain the very anti-corruption predicate, this study suggests maintaining service by upholding the prevailing ethics and norms.

In recent times, the global economy has been subject to increasing volatility, which has made it considerably more difficult to accurately predict economic indicators compared to previous periods. In response to this challenge, the present study conducts an exploratory investigation that aims to predict the Business Survey Index (BSI) by leveraging data mining techniques on both structured and unstructured data sources. For the structured data, we have collected information regarding foreign, domestic, and industrial conditions, while the unstructured data consists of content extracted from newspaper articles. By employing an extensive set of 44 distinct data mining techniques, our research strives to enhance the BSI prediction accuracy and provide valuable insights. The results of our analysis demonstrate that the highest predictive power was attained when using data exclusively from the t-1 period. Interestingly, this suggests that previous timeframes play a vital role in forecasting the BSI effectively. The findings of this study hold significant implications for economic decision-makers, as they will not only facilitate better-informed decisions but also serve as a robust foundation for predicting a wide range of other economic indicators. By improving the prediction of crucial economic metrics, this study ultimately aims to contribute to the overall efficacy of economic policy-making and decision processes.

본 연구에서는 'KRX건설 주가지수'와 '건설업 기업경기실사지수' 간의 관계를 분석하였다. 본 연구는 공표된 주가지수를 '추세요소'와 '잡음거래요소'로 분해하여 '주가지수 추세요소'와 '건설업BSI' 간의 관계, '주가지수 잡음거래요소'와 '건설업BSI' 간의 관계에 대해서 분석하였다는 측면에서 기존연구들과 차별을 두었다. Granger 인과관계 검정 결과에서는 '공표된 KRX건설', '추세요소', '잡음거래요소' 모두 '건설업BSI'에 대해 단방향의 Granger 인과관계가 존재함을 보였다. 즉, 추세요소는 건설업BSI를 선행하는 것으로 나타났으며, 주식시장의 일시적 심리적 요소, 과잉 반응 등에 의해 생성되는 '잡음거래요소'도 '건설업BSI'에 대해 선행관계에 있는 것으로 나타났다. 본 연구결과와 같이 건설업 주가지수의 움직임이 건설업 경영자들의 기대심리에 선행한다는 연구결과는 건설업 경영자들의 투자의욕에 주식시장의 움직임이 영향을 준다는 함의를 제시하고 있다.

경기상황에 대한 기업과 소비자들의 인식을 효과적으로 파악하기 위해 기업경기실사지수 (BSI)와 소비자동향지수 (CSI)를 편제하고 있는 한국은행은 2012년부터 이 두 지수를 합성한 경제심리지수 (ESI)를 추가로 개발하여 발표하고 있다. ESI는 그 유용성을 인정받고 있으나 지수의 예측력 측면에서 개선의 여지가 있는 것으로 나타났다. 본 연구에서는 ESI에 대해 유용성 평가 작업을 실시하고 그 결과를 토대로 현행 ESI의 편제방식의 개선 또는 보완 방법을 모색하였다. 실증분석 결과 ESI 구성요소의 최적 가중치 탐색과정에서 슬라이딩 윈도우 방법을 이용한 동적 최적 가중치 탐색은 기존 ESI의 구성방식을 보완하거나 또는 경제상황을 고려하여 ESI 구성항목들의 가중치를 부여하고자 할 때 매우 유용한 방법이라고 판단할 수 있었다.

OECD countries including Korea positively adopt performance-based budget systems which convert an input-centered system to an output-centered system to solve two baffling problems: public expense retrenchment and efficiency recovery of government management. Output management of IT project propelled in public sector becomes a prominent figure influenced by these keynote of policy. However, it is placed in difficult circumstances to develop a performance index and the methodology to cover characteristics of IT project, measuring the goal achievement of business and the customer contentment according to the phases of business progress. Existing studies of IT project accomplishment measurement have been fulfilled on the subject of business targeting on IT technology application, administrative information network business and national base of information network construction. Most of the studies have been executed using BSC or AHP to reflect synthetically business specifics of IT project from a methodological point of view. In this study, we propose a structural equation model (SEM) to develop a performance index which measures the outcome of IT project according to the phases of business progress, avoiding a simple presentation of project outcome or conceptual frame. The proposed SEM is applied to the survey results of "IT support project for Small and medium business". Based on the fitted model, we apply ACSI concept to develop an Information Technologization Success Index (ITSI). This index allows us comparison of several IT vendors as well as feedback information for further improvement.
