Recently, the mandate on utilizing BIM implemented by public institutions of many countries has great impact on the significantly increasing practices of BIM. The improvement of work efficiency and productivity, which is occurred by BIM adoption, depends on the consistency and accuracy of data. To maximize the benefit of BIM, the interests in BIM data quality have been enlarging all over the world. The BIM data quality pre-check, which is conducted by designer in the design phase, offers opportunities for quality improvement by continuously assessing BIM data. However, BIM quality pre-check is being conducted under arbitrary interpretation of users because of the absence of specific review factors and assessment methods for checking BIM quality. The purpose of this study is to establish an automated BIM quality pre-checking system to improve BIM design quality effectively and efficiently. It could be expected to meet the owner's requirements and to minimize the cost and time occurred additionally from revising and reproducing data by constructing consistency and accuracy of it.

정보통신기술(ICT)과 경영을 융복합적으로 활용한 스마트워크는 언제, 어디서나 편리하고 효율적으로 업무를 수행하는 "일하는 방식의 변화를 통한 일과 삶의 균형"을 추구할 목적으로 2010년 시작되었다. 5년여가 경과한 현재까지 대부분의 스마트워크 관련 연구는 조직에서 스마트워크를 수용하기 전이나 초기 수용 단계에서 진행되었다. 이 때문에 수용 기업에서 스마트워크를 수용하는 과정에서 나타나는 변화관리의 노력, 추진하면서 발생하는 문제점, 활용하면서 얻는 성과 등을 제시하는 데 한계가 있다. 정보시스템을 도입하여 실질적인 성공을 달성하기 위해서는 도입 자체보다는 지속적 사용이 필수적이다. 왜냐하면 사용 빈도가 낮고, 사용 방법이 적절하지 못하고, 사용의 효과가 없을 경우, 해당 정보시스템의 도입은 실패로 규정되기 때문이다. 따라서 본 연구에서는 스마트워크를 성공적으로 도입하여 지속적으로 활용하고 있는 기업을 대상으로 조직에서 시 공간 제약을 극복해 가는 과정과 이를 통해 조직적 성과를 달성하는 과정을 살펴보고자 한다. 이러한 목적을 달성하기 위해 시간지리학과 수용 모델에 기반한 프레임워크를 개발하고, 이를 토대로 도입 기업의 시 공간 제약 극복 과정과 조직 성과를 제시하고자 한다.

Purpose: The purpose of this study was to examine factors related to different stages of mammography screening based on the transtheoretical model (TTM) and health belief model (HBM). Method: 143 women were recruited from community centers in W city. The mean age was 44.08 (SD=7.78) and 74 (51.7%) had experienced education on preventative behavior related to breast cancer. The Decisional Balance Scale (Pros and Cons of mammography) and Stages of Adoption of Mammography Scale by Rakowski et al. (1992) and the revised Health Belief Model Scale (Perceived Seriousness, Perceived Susceptibility and Health Motivation) by Champion (1993) were used. Result: According to the stage of adoption of mammography, 17.4% of the women were In pre-contemplation, 45.5% in contemplation, 24.5% in action, and 12.6% in maintenance. The mean differences for pros, and the decisional balances between the stages of mammography adoption were significant (F=8.84, p=.000; F=7.20, p=.000). Education related to prevention of breast cancer was the most important variable. Prevention education, history of breast disease and pros of mammography explained the stages of mammography adoption ($R^{2}=26%$). Conclusion: Findings support TTM as a useful tool for improving mammography adherence. Behavioral interventions that target decisional balance and health belief can effectively promote adherence to mammography.

DAF process has been designed considering raw water quality characteristics in Korea. Although direct filtration is usually operated, DAF is operated when the freshwater blooms occut or raw water turbidity become high. Pre-sedimentation iS prepared in case when raw water turbidity is very high by rainstorms. A main feature of this plant is that the operation mode can be changed (controlled) based on the characteristics of raw water to optimize the effluent quality and the operation costs. Treatment capacity (surface loading rate) and efficiency of DAF was found to be better than conventional sedimentation process. Moreover, low-density particles (algae and alum flocs) are easily separated while it is difficult to remove in sedimentation. One of the main concerns in adoption of DAF (Dissolved Air-Flotation) process is a high raw water turbidity problem. That is, DAF is not adequate for raw water, which is more turbid than 100NTU. In order to avoid this problem, pre-sedimentation basins are prepared in DAF plant to decrease the turbidity of DAF influent. For simulation of the actual operation, bench and full-scale tests were performed for highly turbid water conditions. Consequently, DAF process coupled with sedimentation is suggested that pre-sedimentation with optimum coagulation prior to DAF would be appropriate.

This study, based on stages of behavioral change, was aimed at suggesting strategies for the adoption of moderate drinking habits for community-based health education designed to help rural people. An interview survey was conducted during the period from March 4 to April 5, 2002 by sampling 467 rural people living in 6 villages covered by a public healthcare clinic. The results of this study can be summarized as follows； 1. The perceived non-moderate drinkers were less prepared for behavioral change. 2. The heavier drinking habits were ‘drinking alone’, ‘meals accompanied by drinking’ and ‘drinking twice or more at a time’. The agricultural off-season and the custom of brewing liquor at home were negative environmental factors for moderate drinking. 3. The predisposing factors affecting moderate drinking were recognition of health, expectation of the drinking effect, etiquette encouraging overdrinking and control of drinking. The reinforcing factors were stress from ordinary life and perception of being loved. The enabling factor was accessibility to the public healthcare clinic. 4. Rural residents are less motivated to participate in health education for moderate drinking. Based on the above findings, health education strategies for each stage can be suggested as follows： 1) Pre-contemplation stage： improvement of perception, motivation, sharing of experiences, and reawakening. 2) Contemplation/preparation stag e： measurement of value, departure from the inertia against a change, formation of a habit, and reinforcement of the behavior. 3) Action/maintenance stage： creation of a social atmosphere, encouragement of participation, change of life style, and improvement of environment.

A three-dimensional physical part can be fabricated from a three-dimensional digital model in a layer-wise manner via additive manufacturing (AM) technology, which is different from the conventional subtractive manufacturing technology. Numerous studies have been conducted to take advantage of the AM opportunities to penetrate bespoke custom product markets, functional engineering part markets, volatile low-volume markets, and spare part markets. Nevertheless, materials issues, machines issues, product issues, and qualification/certification issues still prevent the AM technology from being extensively adopted in industries. The present study briefly reviews the standard classification, technological structures, industrial applications, technological advances, and qualification/certification activities of the AM technology. The economics, productivity, quality, and reliability of the AM technology should be further improved to pass through the technology adoption lifecycle of innovation technology. The AM technology is continuously evolving through the introduction of PM materials, hybridization of AM and conventional manufacturing technologies, adoption of process diagnostics and control systems, and enhanced standardization of the whole lifecycle qualification and certification methodology.

Digitalization and digital transformations have metamorphized the face of Financial Inclusion globally, more so, in cash obsessed economies like India. The purpose of our study is to empirically analyze the users' intention to adopt digital payment systems, post Demonetisation, during the COVID-19 pandemic in India. The conceptual framework for the study is based on the Unified Theory of Acceptance and Use of Technology (UTAUT) adoption model with added operationalized constructs of Perceived Risk and Stickiness to use Cash. A total of 326 respondents were surveyed using a pre-tested questionnaire during the Nationwide Lockdown 3.0 in India. These responses were analyzed using Partial Least Squares - Structural Equation Modelling (PLS-SEM) technique. The findings of the study revealed that performance expectancy and facilitating conditions directly influence the intention of individuals to use digital payment systems, whereas the effect of perceived ease of use on digital payment systems is mediated through the attitude towards the digital payment systems during COVID-19 pandemic situation. Implications of the proposed adoption model are discussed. This will enable the other developing economies to formulate a digital ecosystem, that is here to stay even after the pandemic.

연구목적 기존 정보시스템 연구에서 정보기술 역량과 기업 성과 간 관계에 대해 다양한 관점의 많은 연구들이 있었음에도 불구하고 아직까지 공통된 결론에 이르지는 못하고 있다. 본 연구는 전사적자원관리(ERP) 시스템 도입을 중심으로 정보기술 역량을 파악하여 정보기술 역량과 기업 성과 간 관계에 대한 재고찰을 시도한다. 연구설계/방법론/접근법 기존 관련 연구들은 1990년대나 2000년대 초반의 다소 오래된 기업사례들을 대상으로 하거나 ERP를 도입한 처리그룹과 이에 상응하는 통제그룹을 적절히 매칭하지 못한 채 양자 간 관계를 분석하고 있다는 점에서 자료 및 분석 방법 측면의 문제점을 갖고 있다. 이에 따라 본 연구는 2000년대 후반 들어 전사적자원관리 시스템을 도입한 기업들을 중심으로 성향점수매칭(propensity score matching) 및 이중차이분석(difference-in-difference) 방법을 적용하여 전사적자원관리 시스템을 도입한 기업과 이에 상응하는 미도입 기업을 체계적으로 매칭하고 이들 간의 기간 간 성과 차이를 분석한다. 결과 본 연구 결과에 따르면 전사적자원관리 시스템 도입 기업과 미도입 기업 간 수익성 지표에서 통계적으로 유의한 차이는 없는 것으로 나타났다. 본 연구는 정보시스템의 전유가 경쟁력을 제공했던 과거와 달리 최근 표준화된 정보시스템의 등장과 더불어 단순히 정보시스템 도입 만으로는 더 이상 경쟁 우위를 달성할 수 없다는 점을 시사하고 있다.
