관광지ITS는 해당 관광지역에 관련한 관광과 교통(명승지, 도로망, 주차, 소요시간 등)에 관한 정보를 제공하는 시스템이다. 하지만 관광주유행동의 관점에서 관광지 정보제공 시스템이 아직 충분히 고려되지 못하고 있다. 관광주유행동의 의사결정에 있어 다양한 정보 니즈가 존재하기 때문에 정보이용과 주유행동의 관련성이 매우 중요하다. 본 연구는 관광지ITS구축을 향한 기본적인 정보니즈 분석과 기존 주유행동 모형 재구축의 기초적 시사점 도출을 목적으로 후지5호 관광지의 정보이용과 주유행동의 관련성 분석을 수행하였다. 구조방정식을 이용한 관련성 분석결과, 주유행동의 단계에 따른 정보이용이 지역인지도와 주유행동에 영향을 미치고 있었다. 이는 관광주유행동분야에서도 정보에 의존하고 있다는 점을 밝히고 있다. 또한 이러한 결과는 관광지ITS에 관한 기초적 정보를 제시하고 있다.

This study aims to determine the perceptions of Islamic Financial Cooperative (BMT) managers in the Indonesian BMT Association on the acceptance of core banking technology. The Technology Acceptance Model (TAM) is used because it has simple theoretical characteristics (parsimony) and is supported by data (verifiability). This study develops the TAM model by integrating new variables -perceptions of maqashid sharia, perceptions of economies of scale, perceptions of market structure, and perceptions of technology procurement costs. These new variables are used to measure intention in using technology and actual usage in BMT operations. This study used PLS-SEM with smartPLS 3. The study was conducted in Central Java in six ex-Residency at 35 BMT with 300 respondents consisting of six levels of position level. The research found that maqashid sharia and market structure directly influenced the intention of BMT managers in using core banking technology. This new finding strengthens a theoretical model regarding the role of maqashid sharia in the acceptance of information technology in BMT. In addition, the perception of economies of scale has no significant effect on intention in using technology or its actual usage. The perception variable of technology procurement costs was found to have no significant effect on intention in using technology.

Despite the increasing interest in the positive effects of smart-work, the introduction rate of domestic firms in Korea is lower than that of other developed countries. A gap also exists between the introduction of smart-work program and the actual use by workers. Thus, even if the smart-work program was introduced to firms, the actual usage rate of the program would still be lower than the introduction rate. Moreover, even if the program was initially used, evidence suggests that the usage rate tends to decrease rather than being used continuously. In this study, we intend to find out the mechanism by which the continuance intention of smart-work is formed. To achieve this objective, we established a research model based on literature on Information System (IS) continuance model and Information & Communication Technology (ICT) support. We also hypothesize that concerns about career disadvantage in the mechanism plays a negative role in the satisfaction of smart-work. To analyze the hypothesis empirically, we surveyed domestic workers who used smart-work. Our data analysis was based on 333 responses. We found that all paths were statistically significant, except for the direct effect of ICT support on perceived usefulness and the direct effect of perceived usefulness on smart-work continuance intention. The results of this study extend existing IS continuance model and suggest implications for practical smart-work implementation and improvement.

Purpose: The energy consumption of apartment units is affected by the lifestyle of the residents rather than system technology. In this study the numerical analysis of assumed energy consumption correlation factors with arbitrary value due to uncertainty. It is intended to be used as a simulation correction value which can be utilized as a predicted value of actual energy usage. The correction value of the simulation is set in the developed form of the existing process that derives the actual usage amount. The simulation results used in the existing evaluation system are used to maintain the useful value as the current system evaluation scale and predict the actual capacity. Method: The method of the study is to statistically analyze the data frames of all complexes capable of collecting the annual energy usage and to reconstruct the population by adding the variables that are expected to be correlated. Repeat the data frame configuration with variables that are assumed to be highly correlated with energy use levels. Determine whether there is correlation or not. The intensity of the external characteristics of the building equipment related to the energy consumption is presented as the quantitative value. Result: The correlation between electricity consumption and trading price since 2010 is analyzed as (Correlation coefficient 0.82). These results are higher than (Correlation coefficient 0.79), which is the correlation between residential area and trading price. This paper signifies the starting point of the methodology that broadens the field of view of verification of simulation feasibility limited to the prediction technique focused on the simulation tool and the element technology scope.The diversified phenomenon reproduction method develops the existing energy simulation method.It can be completed with a simulation methodology that can infer actual energy consumption.
