This study aims to facilitate the integration of digital technology into construction supervision by leveraging construction supervision checklists, a fundamental tool for inspections in this field. To achieve this, this research analyzed the tools and practices used in construction supervision, identifying 12 key supervision task types. These task types formed the basis for developing four distinct digital technologies, each tailored to specific inspection tasks based on practical feasibility. A checklist development process followed with the use of predefined criteria. Checklist items from the Ministry of Land, Infrastructure, and Transport of South Korea were analyzed and categorized according to the identified inspection task types. Digital technologies were then integrated for each task type, with corresponding supervision locations documented. This process enhanced the checklist's effectiveness by incorporating methods for digitizing tasks. The findings suggested that approximately 61% of traditional tasks could be potentially replaced by digital technology, highlighting the potential for successful digitization implementation. In addition, surveys among industry professionals provided insights into the level of productivity enhancement achievable through technology adoption compared to traditional practices, offering a basis for predicting productivity improvements across various disciplines. In conclusion, this research supports the effective integration of digital technology into construction supervision through an enhanced checklist. It also sheds light on practitioners' perceptions of technology usage and aids in developing strategies for technology adoption in this domain.

This paper presents a full digital control strategy for parallel connected modular inverter systems. Each modular inverter is a high frequency (HF) AC link inverter which is composed of a HF inverter and a HF transformer followed by a cycloconverter. To achieve equal sharing of the load current and to suppress the circulating currents among the modules, a three-loop control strategy, consisting of a common output voltage regulation (OVR) loop, individual circulating current suppression (CCS) loops and individual inner current tracking (ICT) loops, is proposed. The ICT loops are implemented with predictive current control from which high precision current tracking can be obtained. The effectiveness of the proposed control strategy is verified by simulation and experimental results from parallel connected two full-bridge HF AC link inverter modules.

Input-series-output-parallel (ISOP) converters consisting of multiple modular DC/DC converters can enable low voltage rating switches to be used under high voltage input applications. This paper presents a digital control strategy, which can achieve equal sharing of input voltage for a modular ISOP system consisting of two-transistor forward DC/DC converters by forcing the input voltages of neighboring modules to be equal. The proposed scheme is analyzed using small signals analysis based on the state space average method. The performance of the proposed control strategy is verified with an experimental prototype of an ISOP converter made up of three two-switch forward converters.

In this paper, I applied grounded theory in exploring how Twitter became the battlefield for China's public diplomacy campaign. China's new move to global social media platforms, such as Twitter and Facebook, has been a controversial strategy in public diplomacy. This study analyzes Chinese Foreign Spokesperson Zhao Lijian's Twitter posts and comments. It models China's recent diplomatic move to Twitter as a "war of words" model, with features including "leadership," "polarization," and "aggression," while exerting possible effects as "resistance," "hatred," and "sarcasm" to the global community. Our findings show that by failing to gage public opinion and promote the country's positive image, China's current digital diplomacy strategy reflected by Zhao Lijian's tweets has instead constructed a polarized political public sphere, contradictory to the country's promoted "shared human destiny." The "war of words" model extends our understanding of China's new digital diplomacy move as a hybrid of state propaganda and self-performance. Such a strategy could spread hate speech and accelerate political polarization in cyberspace, despite improvements to China's homogenous network building on Twitter.

Purpose: The research aims to investigate the development of market distribution through digital marketing transformation trends with the support of universities. This development strategy is to maximize sales turnover of limited liability companies' typical traditional beverage products. Research design, data, and methodology: The research design uses descriptive qualitative methods. Data were obtained by participatory observation, in-depth interviews, FGDs, and documentation. Results: The result shows that the partner's traditional product market distribution strategy has been carried out by adopting science and technology and expertise possessed by partner universities. Universities that are Partners have benefited from the implementation of the Independent Campus program. Conclusions: The conclusion from the findings is that business actors must collaborate with universities through the Kedaireka Matchmaking Fund Program. The collaboration will create the right strategy development for the business. The government needs to provide more access to finance in the future. The hope is that the traditional beverage industry and higher education can realize the ease of synergy contributing to national development and the vision of the Indonesian Ministry of Education and Culture's independent campus.

최근의 글로벌 경영환경, 그리고 디지털 미디어를 통한 전자상거래가 활성화되고 있는 상황 하에서 수출기업들의 브랜드 및 웹 도메인 개발에 관한 의사결정은 매우 중요한 전략적 선택이다. 특히 웹 도메인 개발은 기업의 브랜드 전략과 밀접하게 관련되어 있기 때문에 브랜드 개발 시 동시에 개발되는 경우가 대부분이다. 따라서 본 연구에서는 한국수출기업의 해외 브랜드 및 웹 도메인 개발 전략에 관한 수요조사결과를 토대로 수출브랜드전략의 결정요인을 탐색적으로 고찰하기위하여 실행되었다. 이를 위하여 본 연구에서는 브랜드전략 결정요인으로 수출경쟁력, 시장의 유사성, 환경의 불확실성으로 구분하고 브랜드 전략과의 관계를 회귀분석 하였다. 연구결과 한국수출기업의 경우에 기대한 바와 같이 수출경쟁력이 높을수록 OEM브랜드 수출비중이 낮고, 환경의 불확실성이 클수록 OEM브랜드 수출비중은 높은 것으로 나타났다. 그러나 시장의 유사성은 통계적으로 유의한 영향을 미치지 못한 것으로 나타났다. 자사브랜드 전략을 사용하고 있는 기업의 경우에도 수출경쟁력이 높은 기업일수록 글로벌브랜드를 선택하는 경향이 높고 환경의 불확실성이 클 경우에는 로컬브랜드 전략을 선택할 가능성이 높은 것으로 나타나 가설을 지지하였다. 그러나 시장의 유사성은 글로벌브랜드 전략 또는 로컬브랜드 전략과의 유의미한 통계적 관계를 보여주지 못했다.

This study purports to examine the current management and information technology related strategy of Korean hospitals and suggest the effective management strategy in the 21st century when is digital era. Specifically the study tries to analyze the changing trends of strategic orientation and investigate the general management and information technology strategy of Korean hospitals. Self-administered Questionnaires were distributed to 721 hospitals nationwide and finally 98 Questionnaires were analyzed for the study. The results of the study are as follows : 1) Half of the respondent hospitals reported that they have an analyzer orientation in 2000, whereas 19.4% were prospectors, reactors 16.4%, and defenders 14.3%. However, the respondent hospitals intended to have a prospector orientation in the future (2002), while 29.6% planned on being analyzers, 17.3% reactors, and 3.1% defenders. 2) Hospital services for improving patient satisfaction were the most common. strategy for the respondent hospitals, followed by cost containment, organizational restructuring, employee education, purchasing system change, specialization of clinical services, quality improvement of medical care, strengthening the networking with the stakeholders, public relations and marketing strategy, diversification, and installing the information system. However, the strategies of annual salary system, retrenchment of unprofitable services, merit payment based on performance were still not popular for the respondent hospitals. 3) As for the strategies related with information technology, most hospitals have not implemented actively, except for the establishment of home-pages, order communication systems, and insurance claims through electronic data interchange system. 4) There were significant differences in the level of strategy implementation in terms of the ownership, bed size, financial performance, and the top managers I knowledge of information technology. The larger bed size, the higher financial performance, the better knowledge of information technology the top managers have, the more strategies the respondent hospitals implemented. The managerial and political implications for Korean hospitals in digital era were also discussed.
