A big data-driven digital transformation is defined as a process that aims to innovate companies by triggering significant changes to their capabilities and designs through the use of big data and various technologies. For a successful big data-driven digital transformation, reviewing related literature, which enhances the understanding of research statuses and the identification of key research topics and relationships among key topics, is necessary. However, understanding and describing literature is challenging, considering its volume and variety. Establishing a common ground for central concepts is essential for science. To clarify key research topics on the big data-driven digital transformation, we carry out a comprehensive literature review by performing text mining of 439 articles. Text mining is applied to learn and identify specific topics, and the suggested key references are manually reviewed to develop a state-of-the-art overview. A total of 10 key research topics and relationships among the topics are identified. This study contributes to clarifying a systematized view of dispersed studies on big data-driven digital transformation across multiple disciplines and encourages further academic discussions and industrial transformation.

Utilizing a qualitative multimethod approach, this study was to discover and improve the understanding of occupational socialization process of librarians. Through theoretical sampling, 42 participants were in-deathly interviewed at three studies, i.e phenomenological, ethnographic, and grounded theory approach. Analyzed data were finally integrated using grounded theory approach. 'Acquiring Social Recognition as an Information Professional' was emerged as the core category for describing and guiding the occupational socialization process. A seven-stage process was discovered: 'Adapting', 'Experiencing being the Periphery', 'Perceiving the Role', 'Pursuing the advancement', 'Realizing the professionality', 'Rediscovering the Value', and 'Showing the Professionality'. Especially, 'Experiencing being the Periphery' was identified as a critical and unique process, reflected the perceived status of librarians in Korea. Also, it discussed characteristics and socialization strategies of the process.

In this study, a GIS-supported system is used to measure the effect of social infrastructure improvements. Benefit evaluation approach is based on two types of approaches -the simple hedonic approach and Rosen's two step approach. The land attribute data for both approaches are efficiently collected and generated in a GIS-supported environment. Moreover, it conveys more objective and correct data. The benefits are estimated on real locations by using GIS. The potentiality of the developed system for practical application has been verified by its application to Joban New Line in Tokyo metropolitan area. By incorporating benefit evaluation routines into GIS, the proposed system will be a useful tool for decision making on the improvements of social infrastructure.

Objective : This study aimed to provide an overview of task-oriented approaches for children with developmental coordination disorder, including its definition, diagnosis, causes, and assessment, through a literature review. Subject : Eighteen international articles published between January 2000 and September 2023 were analyzed to explore the intervention strategies of Neuromotor Task Training (NTT) and Cognitive Orientation to daily Occupational Performance (CO-OP). The objectives of the interventions mentioned in the reviewed articles were categorized according to the criteria of the Occupational Therapy Practice Framework-4 (OTPF-4). The results showed that NTT more frequently set goals in the area of client factors, while CO-OP set goals only in the area of occupation. This difference in goal setting can be explained by the strategy differences between the two interventions. Conclusion : A broader and deeper understanding of strategies for interventions with task-oriented approaches to developmental coordination disorder can increase awareness of the disorder and provide a more solid basis for evidence-based practice.

전통적인 HRA(Human Reliability Analysis)방법은 특정 애플리케이션 또는 산업을 염두에 두고 있으며. 또한 이러한 방법은 종종 복잡하며, 시간이 많이 걸리고 적용하는 데 비용이 많이 들며 직접 비교하기에는 적합하지 않다. 제안된 HFHM(Human Factors Hazard Model: 인적 요인 위험 모델)은 기검증되고 시간 테스트를 거친 FTA(Fault Tree Analysis:결함 트리 분석)및 ETA(Event Tree Analysis:이벤트 트리 분석)의 확률 분석 도구 및 새로 개발된 HEP(Human Error Probability:인적 오류 확률)예측 도구와 통합되고, 인간과 관련된 PSF(Performance Shaping Factors:성능 형성 요인)를 중심으로 새로운 접근 방식으로 개발되었다. 인간-시스템은 상호작용으로 인한 재난사고 가능성을 모델링하는 위험분석 접근법 HFHM은 다음과 같은 상용 소프트웨어 도구 내에서 예시되고 자동화된다. HFHM에서 생성된 데이터는 SE 분석가 및 설계에 대한 표준화된 가이드로 사용될 수 있다. 본 연구에서는 인적 위험을 예측하는 이 새로운 접근 방식을 통해, 전체 시스템에 대한 포괄적인 재난안전 분석을 가능하게 한다.

우리나라에서 물관리체계를 개편하려는 노력은 오랜 역사를 가지고 있다. 물관리기본법의 추진은 1990년대 후반기의 입법부(1997년), 2000년 전반기의 시민사회(2000년~2004년), 2000년대 후반기의 행정부(2005년~2008년) 주도로 국회에 상정하였으나 실패하였다. 그러나 2009년 정치권인 입법부에서 3명의 국회의원이 물관리기본법안을 각각 대표발의를 하였다. 국회에 발의된 3개의 물관리기본법안은 기존 물관리체계의 행정적, 업무적 비효율을 개선한다는 점에서 동일한 시각에서 접근하였다. 또한 기후변화에 대한 능동적인 대응과 지속가능한 발전, 그리고 삶의 질 향상과 같은 다양한 요구를 수용하고자 하는 노력을 확인할 수 있다. 본 연구의 목적은 18대 국회에 발의된 3가지 물관리기본법안에 대한 심층적인 비교검토를 통하여 논리적인 장단점을 분석하는 것이다. 이를 위하여 3가지 법안별로 유사점과 차이점을 분석하고 통합물관리의 이론에 입각한 방향성을 파악하였다. 물관리체계의 개편은 단순히 행정조직의 구조개편이 아닌 통합물관리라는 큰 틀(big picture) 속에서 재구성되어야 한다. 본 연구에서 파악한 3가지 물관리기본법안에 대한 비교검토는 우리나라에서 미래지향적이고 효율적인 물관리구조를 조기에 정착시키는데 큰 기여를 할 것이다.

The improvements of berth productivity is closely related to berth/port systems and its relationship extends to the overall pattern of port development/logistics, transport and trade. Since ports in general and berths in specific function as a bridge transferring seaborne cargoes from seaside to landside and vice versa, berth productivity improvements should be considered in terms of the total system in which the cargoes are transported from origin to destination via berths/ports. In that respect, the objective of this study is to improve berth productivity which is a vital factor in the strategic planning in port development and operation and logistics. According to a literature survey on the subject, the contents of the studies have been limited to either a macro-perspective or a micro-perspective which is only a partial solution to the problem. Hence, this limitation requires an integrated approach to find and ultimate solution, which should be considered not separately, but as a whole. The contents and scope of this study cover the improvements of berth productivity in conjunction with strategic planning in port development. efficient operation and logistics from two different viewpoints, macro- and micro-perspective. After that, a combination of these two perspectives is applied to the integrated approach due to lacking a comprehensive perspective from either macro-approach or micro-approach. In reality, a port itself is a complex and dynamic organization. Therefore, a comprehensive insight needs an integrated approach for the long-term national economic development. In this approach, the utmost importance is how to find the bottlenecks and to solve the problems effectively from the beginning stage in port development. In conclusion, derived from the macro- and micro-perspective. the attempt to establish an integrated approach is the merit of this study, which is required as a comprehensive measure since none of the two can be a solution independently. In terms of reinforcing this study, it needs further empirical research due to the restriction of the theoretical method of this paper. Consequently, the reinforced research will be able to enhance the integrated approach on the basis of the conceptual perspective.

The following research investigates core factors required for IT professionals to achieve and remain happy on their jobs through dynamic and structural CLD and suggests personal, organizational, and government level (happiness) promoting factors. Researcher adopted the system dynamics methodology which is qualitative research techniques pursue behavior probability by using CLD. It spotlights 6 CLD: job satisfaction, organizational commitment, positive sensitivity, negative sensitivity, amicable relationship, job sustainment intention, in addition to numerous factors that affect them from an integrative perspective. It differentiates itself from one-way relationship focused qualitative research to an advanced mutual and realistic perspective exploratory research.
