이충형,김영준,Lee, Choong-Hyong,Kim, YoungJun 한국융합학회 2021 한국융합학회논문지 Vol.12 No.8

4차산업혁명시대에 정보통신기술의 비약적인 발전, 고객구매 성향의 다양함, 복잡함은 산업 전체적으로 데이터의 양적 중가를 가져와 '빅데이터' 시대를 맞이하게 되었다. 빅데이터 시대는 데이터를 분석, 활용하여 기업의 전략적 의사결정에 활용하는 것이 기업의 핵심 역량으로 자리 잡게 되었다. 하지만 현재 빅데이터 연구들은 기술적 이슈와 미래 잠재 가치 중심이었다. 반면 기업이 보유한 내.외부 고객 빅데이터의 품질 및 활용 수준관리에 대한 연구와 논의는 부족하였다. 본 연구에서는 기업의 내.외부 빅데이터 품질관리 정보시스템 측면와 품질경영 측면으로 인식하여 영향요인을 도출하였다. 또한 빅데이터 품질관리, 빅데이터 활용 및 수준관리가 기업의 업무 효율화와 기업 경영성과에 유의한 영향을 미치는지 204명의 임직원 설문을 통해 조사하였고, 가설을 설정하여 검증하였다. 연구결과 경영층의 지원, 개인 혁신성, 경영환경변화, 빅데이터 품질활용 지표관리, 빅데이터 거버넌스 체계 마련이 기업 경영성과에 유의한 영향을 미쳤다. The Fourth Industrial Revolution brought the quantitative value of data across the industry and entered the era of 'Big Data'. This is due to both the rapid development of information & communication technology and the diversity & complexity of customer purchasing tendencies. An enterprise's core competence in the Big Data Era is to analyze and utilize the data to make strategic decisions for enterprise. However, most of traditional studies on Big Data have focused on technical issues and future potential values. In addition, these studies lacked interest in managing the quality and utilization levels of internal & external customer Big Data held by the entity. To overcome these shortages, this study attempted to derive influential factors by recognizing the quality management information systems and quality management of the internal & external Big Data. First of all, we conducted a survey of 204 executives & employees to determine whether Big Data quality management, Big Data utilization, and level management have a significant impact on corporate work efficiency & corporate management performance. For the study for this purpose, hypotheses were established, and their verifications were carried out. As a result of these studies, we found that the reasons that significantly affect corporate management performance are support from the management class, individual innovation, changes in the management environment, Big Data quality utilization metrics, and Big Data governance system.

이충형,최영근,황성규,함인석,박연묵,김승래 慶北大學校 醫科大學 1993 慶北醫大誌 Vol.34 No.4

1992년 6월부터 1993년 8월까지 경북대학교병원 신경외과에 입원한 흉요추부 척추 손상 환자중 신경손상을 동반한 환자, 심한 불안정성을 보인 환자 및 추적관찰중 척추후만의 진행과 함께 심한 배부 동통을 호소한 환자를 대상으로 VSP나 ISOLA기기를 사용하여 감압, 고정술 및 골유합술을 시행하고 3내지 17개월(평균 12개월)간을 추적관찰하였다. 환자는 모두 남자였으며 연령은 20세에서 59세 사이로 평균연령은 41세었다. 손상의 원인은 추락, 교통사고, 골절부위의 직접외상이 각각 4예였다. 손상의 부위는 제11흉추 1예, 제12흉추 3예, 제1요추 4예, 제2요추 2예, 제3요추 2예로 제1요추가 제일 많았다. 신경학적 장애도 2예는 완전손상, 8예는 부분손상, 2예는 정상범위였다. 충분한 감압과 기기를 이용한 내고정술, 골유합술 시행후 조기운동을 시행하였다. 수술 1내지 2주후부터 4지 6개윌간 흉요추부 보조기를 착용하였다. 합병증은 수술부위 1예에 대하여는 발견즉시 혈종제거로 호전되었고, 수술부위에 감염이 발생된 2애에서도 각각 약 1개월간 투여로 호전되었다. 본 수술방법은 가능한한 조기에 충분한 감압고정으로 신경회복을 최대한 기대할 수 있으며 조기에 더 이상의 신경손상에 대한 염려없이 움직일 수 있어 장기간 침상안정에 따른 합병증을 예방할 수 있는 좋은 치료방법으로 사료된다. From June 1992 to August 1993, 12 patients with thoracolumbar injuries of the spine were treated with VSP or ISOLA system and fusion. This report present the results of this procedure relates to decompession, stabilization and return of neural function. Solid fusion was obtained in all. Eight patients with incomplete or cauda equina lesions were much improved, which two patients^with complete lesions remained unchanged. The advantages of this procedure are effective stabilization which allowed early ambulation without further neuronal injury, adequate decompression and solid fusion.

Do Brand Love and Brand Knowledge Matter? Impact on Brand Relationship and Extra-Role Behavior

이충형,송자현,우현아 (사)한국조리학회 2022 한국조리학회지 Vol.28 No.7

As consumers increasingly exhibit various altruistic behaviors that contribute to brand value on social media channels, much academic attention has been devoted to exploring when and how such extra-role behaviors (e.g., providing feedback and helping other customers) can be achieved. Researchers acknowledged that cognitive knowledge and affective attachment a consumer holds for the brand impacts the level of customer-brand relationships and resulting behaviors. However, there exists little empirical research on the effects of these two key factors. Thus, this study aimed to shed some light on the research field by proposing and empirically testing a conceptual model of self-brand connections that considers brand knowledge and brand love as potential antecedents and social media-based contributing behaviors as a consequence. Results from structural equation modeling analysis demonstrate that brand love enhances customer-brand relationships, which in turn, lead to extra-role behaviors. However, the influence of brand knowledge was minimal. Implications are discussed for effective management of cultivating brand advocates.

What If Instantaneous Relative Velocity Is Real In Special Relativity: Relative Simultaneity As Indexed Relation

이충형 한국분석철학회 2022 철학적 분석 Vol.- No.47

It is a standard view in Special Relativity that simultaneity relations are ternary relations that hold for three items: x is simultaneous with y relative to z. Noting the connection between clock synchrony and the one-way speed of light, I argue that if it is indeed a physical fact that the one-way speed of light has a certain value, then simultaneity relations in Special Relativity are about local facts that obtain in finite spatiotemporal regions, and so it is natural and plausible to take simultaneity relations to be quaternary relations among four items, i.e., x is simultaneous with y relative to z at p, where p is a spatiotemporal point in Minkowski spacetime. This has the added benefit of defusing Hanoch Ben-Yami (2006)’s argument that Standard Synchrony yields inconsistent results when applied to non-inertial observers.

A Puzzle of Infinitely Many Mutually Independent Bets

이충형 한국분석철학회 2018 철학적 분석 Vol.0 No.40

I present a new puzzle where a player is offered infinitely many mutually independent bets each of which has a positive expected return but which collectively lead to a net loss almost surely with probability 1. This puzzle is similar to the one presented by Vann McGee (1999) where there are infinitely many mutually dependent bets each of which has a positive expected return but whose cumulative outcome is a sure loss. Both puzzles pose a serious threat (while my new puzzle, because of the mutual independence of the bets, poses a more serious threat) to the principle of expected utility maximization because the principle seems to recommend us to take each and every one of the bets whereas it does not seem rational to take all of them. I then argue that the two puzzles can be solved in a uniform way: It is impossible to take all of the bets if you have only a finite amount of money and it is not irrational to take them all if you have an infinite amount of money.

이충형,김병훈,황성규,함인석,박연묵,김승래 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.6

뇌지주막하 출혈을 일으킨 개두술을 받은 268명의 뇌동맥류 환자중 술전 두부전산화 단층 촬영상에서 뇌실질내에 출혈을 일으킨 65명의 환자를 대상으로 하여 동맥류의 발생부위, 뇌실내 출혈의심도, 술후 뇌실의 확장 및 치료의 결과를 분석, 검토하였다. 뇌지주막하 출혈을 일으킨 뇌동맥류 환자에서 뇌실내 출혈의 발생빈도는 24.3%였다. 동맥류의 발생부위 별로는 전교통 동맥류가 49.2로써 가장 높은 빈도를 나타내었으며 다음이 후교통 동맥류로써 15.4%였다. 뇌실내 출혈의 심도는 severe IVH(intraventericular hemorrhage)를 나타낸 것이 49.2%로써 가장 많았으며 다음이 mild IVH로써 32.3%의 빈도를 나타내었다. 뇌실확장은 41.5%에서 관찰되었으며 ventericular size index(VSI)에 의한 mild dilatation은 7.7%, moderate가 13.8% 그리고 severe는 20%로 분석되었다. 뇌척수액의 이동술은 11명(16.9%)에서 시도되었다. 뇌실내 출혈을 일으킨 65명의 뇌동맥류 환자에서 퇴원시를 기준으로 한 치료의 결과는 생존자가 58명으로써 89.3%이었으며 Good 상태로 회복된 것은 32.3%이였다. 그리고 사망은 7명으로써 10.7%의 사망율을 나타내었다. Clinical analysis and review were made on the 65 aneurysmal patients who had intraventricular hemorrhage(IVH) confirmed on preoperative brain CT among a total of 268 patients operated on intracranial aneurysms. The study was made on aneurysmal sites, the severity of IVH, postoperative ventricular dilatation and the result of treatment The frequency of IVH among the 268 aneurysmal patients with direct clipping was 24.3 % . Aneurysms originated from anterior communicating artery had the highest frequency(492%), followed by from posterior communicating artety(l5.4 % ). On the severity of IMI, the frequency of severe IMI was 492 % , the highest. The second was mild IVH, 323%. Forty five percent accounted for ventricular dilatation. By ventricular size index, mild dilatation was 7.7% : moderate, 13.8% and severe dilatation 20%. 11 patients(l6.9%) underwent CSF shunting procedure. The treatment for the 65 eneurysmal patients with IVH ended in survivor, 58 patients(98.3 % >, good recovery, 32.3% and 7 deaths the rate of mortality was 10.7%.

Design to Improve Educational Competency Using ChatGPT

이충형 한국인터넷방송통신학회 2024 International Journal of Internet, Broadcasting an Vol.16 No.1

Various artificial intelligence neural network models that have emerged since 2014 enable the creation of new content beyond the existing level of information discrimination and withdrawal, and the recent generative artificial intelligences such as ChatGPT and Gall-E2 create and present new information similar to actual data, enabling natural interaction because they create and provide verbal expressions similar to humans, unlike existing chatbots that simply present input content or search results. This study aims to present a model that can improve the ChatGPT communication skills of university students through curriculum research on ChatGPT, which can be participated by students from all departments, including engineering, humanities, society, health, welfare, art, tourism, management, and liberal arts. It is intended to design a way to strengthen competitiveness to embody the practical ability to solve problems through ethical attitudes, AI-related technologies, data management, and composition processes as knowledge necessary to perform tasks in the artificial intelligence era, away from simple use capabilities. It is believed that through creative education methods, it is possible to improve university awareness in companies and to seek industry-academia self-reliant courses.

A Tale of Team Infinity

이충형 한국분석철학회 2017 철학적 분석 Vol.0 No.38

I construct a decision-theoretic puzzle based on the assumption that it is possible for there to be a team of infinitely many people whose utility scales are unbounded. I argue that the puzzle can be resolved, without requiring that no rational agent should have unbounded utility scales, by employing a more general definition of utility, on which utility is measured not by amounts of returns but by changes in total wealth.
