  • 플랫폼은 기존 전통적인 선형적 파이프라인 기반 비즈니스 모델에 대응하는 대안으로 떠오르고 있다. 특히 최근의 4차 산업혁명시대에 효율성 주도의 파이프라인 기반은 조정 주도의 플랫폼 기반으로 변환되어야 한다는 것이 일반적인 인식이다. 플랫폼 성공사례는 애풀, 구글, 아마존, 우버 등에서 쉽게 찾을 수 있다. 그러나 규모가 크지 않은 기업에서는 플랫폼 비즈니스로의 전환 전략을 찾기가 쉽지 않다. 플랫폼 비즈니스의 핵심은 네트워크 효과를 경영활동에 도입하여 활용하는 것이다. 따라서 플랫폼 비즈니스는 경영활동 기능에서 네트워크 효과 관리를 어떻게 할 것인가와 유사하다. 플랫폼 관련 연구는 최근 활발하고 다양하다. 그러나 이 분야의 연구 동향에 대한 연구는 많지 않다. 본 연구의 주요 목적은 최근 국내에서 수행된 플랫폼 관련 연구를 통하여 연구동향을 이해하는 것이다. 이를 위해서 우리는 연구가설과 명제를 제시하였다. 데이터는 연구논문으로 한국학술지인용색인 시스템에서 "플랫폼" 혹은 "platform"을 키워드 속성으로부터 얻었다. 수집된 논문집합은 "경영학" 분야로 국한하여 구성하였다. 선택된 논문들을 대상으로 연구된 플랫폼 요소, 플랫폼 유형, 주요 연구 내용 등에 대해 56개의 논문에 대해 분석을 하였다. 56개의 데이터를 이용하여 탐색적인 연구가설을 검증하였고, 명제를 제안하였다. 본 연구의 시사점은 연구자들에게 연구 영역 중, 많은 연구가 수행되어 온 성숙 영역과 아직 더 많은 연구가 필요한 분야를 제시하였다. 또한 실무자들에게는 파이프라인 비즈니스로부터 플랫폼 기반 비즈니스로 변화를 추구하는 가이드라인을 제시한 것이다. 가이드라인의 핵심은 극대화하기 위해서는 IT플랫폼 시스템을 기반으로 소비자와 공급자 네트워크를 점진적으로 조정하고 관리하여야 한다는 것이다. 본 연구는 데이터 수집과 수집된 데이터의 구분 및 주요 연구내용 등 주관적인 판단 요소가 많아 추론적이 아닌 탐색적 연구로 간주되어야 할 것이다.

  • 공간정보 오픈플랫폼에서는 국가공간정보를 공개하여 국민이 자유롭게 활용할 수 있는 서비스를 제공하고 있다. 최근 고품질의 3차원 공간정보와 실내공간정보에 대한 수요가 증가하고 있으나, 현재 오픈플랫폼은 실내와 실외의 공간정보 데이터가 상이한 형식과 저장구조로 구성되어 매끄럽게 연결된 서비스가 불가능한 상황이다. 또한 현재 서비스에 사용되는 3차원 데이터 포맷이 최근 서비스 환경의 변화와 신기술을 반영하지 못하고 있는 실정이다. 따라서 본 연구에서는 오픈플랫폼 3차원 데이터의 서비스 향상 및 상호운영성 확보를 위하여 서비스에 사용되는 3차원 데이터 포맷의 개선방안을 제시하였다. 제안한 포맷은 기존 포맷과 비교하여 경량화되었고 렌더링 속도가 개선되었다.

  • With the advent of high technologies such as the 4th Industrial Revolution and artificial intelligence and big data, efforts are being made to solve urban problems and improve the quality of life by applying new technologies in the smart city field. In addition, as carbon neutrality has emerged as an important issue due to global warming, smart city energy platform technologies such as urban energy management, efficiency improvement, and carbon reduction are in the spotlight. In order to effectively manage urban energy, energy resource information such as electricity, water, gas, hot water, heating, etc. must be collected from the management system of various energy utilities and managed on the central platform. The centrally integrated data is delivered to external city management systems that require city energy information through an energy platform. This study developed a CIM profile for smart city energy monitoring required to provide energy data to external systems. Electric data model were designed using the CIM class of IEC 61970, and water, gas, and heat data model were designed in compliance with the UML-based design ideas of IEC 61970.

  • Despite the maturity of platforms, only some studies have explored the relationships between the working conditions of platform workers and their organization-like responses to these platforms. Thus, this research utilized the Job Demands-Resources Model (JD-R Model) to analyze the effects of job demands and resources on platform workers' job embracing. The data were collected from 182 food delivery riders in South Korea. This study utilized the PLS technique (partial least squares) to examine the research model. Regarding job demands, this study has found that work overload and physical effort significantly affect burnout. Regarding job resources, the results revealed that service technology support and training significantly affect work engagement. In alignment with the Job Demands-Resources literature, the findings offer tangible proof that burnout has a detrimental impact on job embracing, whereas work engagement has a beneficial effect on job embracing. Our findings indicate that work engagement exerts a more substantial beneficial effect on job embracing, and burnout reduces job embracing. Results also provide novel insights to scholars seeking a comprehensive research model on the impact of on-demand workplace conditions to help platforms attract and retain platform workers.

  • Safety accidents are of concern during construction projects, even given the recent innovations in digital technologies. These projects remain focused on overcoming specific and limited applications on construction sites. For this reason, the development of an inclusive safety management system has become crucial. This study aims to build a Big Data platform to inform decisions on how to proactively eliminate worker hazards on construction sites. The platform consists of about 100,000 real records and a real-time monitored database featuring various safety indices, such as workers' altitudes, heart rates, and fatigability during construction, which are determined through various wearable devices. The data types are customized and integrated by a research team in accordance with the characteristics of a specific project using hypertext transfer protocol (HTTP). The results can be helpful as efficient tools to ensure successful safety management in complex construction situations. This study is expected to provide three significant contributions to the field, including real-time fatigability analysis and tracking of workers on-site; providing early GPS-based warnings to workers who might be accessing dangerous spaces or places; and monitoring the workers' health indices, based on details from 100,000 cases.

Research design, data and methodology: A survey was conducted targeting OTT platform users in their 20s to 40s nationwide from August 10 to 16, 2022, and a total of 208 people were used in the final analysis. To verify the research model, frequency analysis, CFA, and SEM analysis were performed using SPSS and AMOS. Results: First, the perceived value of the OTT platform was found to have a positive effect on consumers' technology acceptance (perceived usefulness, perceived ease of use, and perceived enjoyment). Second, the perceived ease of use of OTT platform consumers was found to have a positive effect on perceived usefulness and perceived enjoyment. Third, it was found that the perceived usefulness and perceived enjoyment of OTT platform consumers had a positive effect on the continuous use intention, and WOM. Fourth, it was found that the continuous use intention the OTT platform had a positive effect on the WOM. Conclusions: Word of mouth and continuous use of existing customers are important for OTT platform companies to retain existing customers and secure new customers. Through the perceived value of the OTT platform, efforts should be made to provide various contents that consumers can enjoy along with usefulness and convenience of functions.

  • With the development of advanced technology, automation of agricultural work is spreading. In association with the 4th industrial revolution-based technology, research on field smart farm technology is being actively conducted. A state-of-the-art unmanned automated agricultural production demonstration complex was established in Naju-si, Jeollanam-do. For the operation of the demonstration area platform, it is necessary to build a sophisticated, advanced, and intelligent field smart farming model. For the operation of the unmanned automated agricultural production demonstration area platform, we are building data on the growth of soybean for smart cultivated crops and conducting research to determine the optimal time for agricultural work. In order to operate an unmanned automation platform, data is collected to discover digital factors for water management immediately after planting, water management during the growing season, and determination of harvest time. A subsurface drip irrigation system was established for smart water management. Irrigation was carried out when the soil moisture was less than 20%. For effective water management, soil moisture was measured at the surface, 15cm, and 30cm depth. Vegetation indices were collected using drones to find key factors in soybean production prediction. In addition, major growth characteristics such as stem length, number of branches, number of nodes on the main stem, leaf area index, and dry weight were investigated. By discovering digital factors for effective decision-making through data construction, it is expected to greatly enhance the efficiency of the operation of the unmanned automated agricultural production demonstration area.
