손재열,김휘중,이슬기,송재헌,정재필 대한용접·접합학회 2021 대한용접학회 특별강연 및 학술발표대회 개요집 Vol.2021 No.5

전자 부품의 고성능화, 초소형화, 저전력화 및 스마트화가 진행됨에 따라 interposer를 사용하는 2.5D 혹은 PKG를 적층하는 3D 구조 변화가 진행되고 있다. 이러한 적층 구조에서는 솔더볼을 사용 시 상부 PKG 무게로 인해 솔더범프가 주저앉아 주변의 솔더범프와 전기적인 short를 발생시키거나 substrate와 interposer 사이에 Si Chip이 실장되는 경우 Chip의 damage를 유발시키게 된다. 따라서 stand-off특성 이 우수하며, 안정된 접합 신뢰성을 나타낼 수 있는 제품 소재의 개발이 필요하다. 본 연구에서는 3D PKG구현을 위한 접합소재로써 일반적인 SAC305 솔더볼과 CCSB (Cu Core Solder Ball)의 변형 응력 차이점 관찰과 접합 특성 관찰을 진행하였다. Flip Chip Bonder를 사용하여 RT과 175’C 조건에서 압축 응력 인가에 따른 deformation이 발생되는 현상을 연구하였다. 시험 결과 Solder ball 대비 CCSB 구조가 매우 우수한 stand-off 특성을 유지하는 것으로 확인되었다. 또한, Dage4000모델을 이용하여, multiple reflow에 따른 접합강도의 차이점을 비교 분석하였으며, FE-SEM 및 EDS를 통해 micro structure의 변화를 관찰하였다. Reflow공정을 통해 접합 시 표면의 산화막 두께가 클 경우 non-wetting현상이 발생될 수 있다. 따라서, 접합의 안정성 여부를 확인하기 위하여, AES를 이용한 산화막 두께 또한 확인하였다.

노상열 ( No Sang-yeol ),손재만 ( Son Jae-man ),고성호 ( Ko Sung-ho ) 경기대학교 관광종합연구소 2019 여가관광연구 Vol.31 No.-

본 연구를 통해 오버투어리즘, 투어리스티피케이션과 같은 사회적으로 논의하고 있는 관광의 문제점을 우도라는 대상지를 특정하여 사회·심리적 수용력과 지역주민의 삶의 질에 대한 인과관계를 알아보고자 노력하였다. 이를 통해 본 연구에 대한 결론을 정리하면 다음과 같다. 첫째, 우도의 지역주민들은 방문한 관광객에 대해 사회·심리적으로 혼잡을 지각할수록 경제 만족 및 거주 만족에 부정적인 영향을 받고 있었고, 데이터를 분석한 결과 ‘주민 혼잡지각이 낮을수록, 주민거주 만족이 높다’, ‘주민 혼잡지각이 높을수록 주민 경제 만족이 낮다’라는 결론을 도출할 수 있었다. 둘째, 우도의 지역주민들은 방문한 관광객에 대해 사회·심리적으로 불쾌지각을 느끼는 것과 경제 만족 및 거주 만족에 유의한 인과관계를 발견할 수 없었다. 이를 통해서 우도의 지역주민들은 관광객에 대해 혼잡함이나 불쾌감을 인지하고 있지만, 대체로 삶의 질을 평가하는 요소에 많은 영향을 받지는 않는 것으로 판단된다. Through this study, we tried to find a causal relationship between social and psychological capacity and the quality of life of local residents by designating the subject of preferential treatment for the problems of tourism that are being discussed socially, such as over-tourism and tourism. This summarizes the conclusions of this study. First, local residents of Udo Island were negatively affected by economic and residential satisfaction as they perceived social and psychological congestion, and the analysis of the data led to the conclusion that 'the lower the resident congestion awareness, the higher the resident residence satisfaction level, and the higher the resident congestion awareness, the lower the resident's economic satisfaction level. Second, the local residents of Udo could not find any causal relationship between feeling socially and psychologically unpleasant about the visitors they visited and significant economic and residential satisfaction.

인터넷 개인방송의 상호작용성이 플로우를 매개로 시청자의 후원 행위 의도에 미치는 영향

강윤선,손재열 한국인터넷전자상거래학회 2020 인터넷전자상거래연구 Vol.20 No.5

With the widespread acceptance of online live streaming services, a growing number of creators try to earn money by providing contents on live streaming services. The purpose of this study is to examine the role of interactivity in increasing online live streaming service viewers’ intention to donate money for content creators. Specifically, we posit that interactivity conceptualized in terms of two-way communication, responsiveness, and active control would lead the viewers to experience flow, which in turn increases their intention to donate money for the content creators. Data collected via an online survey to 118 online live streaming service viewers confirm our assertion that each of two-way communication, responsiveness, and active control has a positive effect on the viewers’ flow experience with subfactors of enjoyment, focused attention, time distortion, and telepresence. In addition, flow is found to have a positive effect on their intention to donate money for the content creators. Based on the results of this study, we recommend that the online live streaming service platform and creators develop various ways to increase interactivity in terms of two-way communication, responsiveness, and active control, so as to maximize their profit from the donation of the viewers.

온라인 게임 내 사용자 간 상호작용이 지속사용의도에 미치는 영향: 경쟁과 협력을 중심으로

도현진,손재열 한국인터넷전자상거래학회 2019 인터넷전자상거래연구 Vol.19 No.6

This study aims to examine the impact of social interactions among users in online games on the continued use of online games, with a focus on competition and cooperation. In particular, we identify interpersonal competitiveness and goal competitiveness as two subfactors of competition and reciprocity and goal interdependence as two subfactors of cooperation. According to the theory of self-determination, the more actions that affect intrinsic motivation, the more humans experience self-deterministic and positive emotions. Perceived enjoyment and sense of accomplishment are considered to be closely related to intrinsic motivation. This study argues that those subfactors of competition and cooperation affect perceived enjoyment and sense of accomplishment, which in turn influence continuance intention through the feeling of flow. Analysis of data collected from an online survey offers empirical evidence for the effects of subfactors of competition and cooperation on perceived enjoyment and sense of accomplishment. We also found that perceived enjoyment and sense of accomplishment affect game users’ continuance intention through the feeling of flow. Our study suggests that game developers should stimulate competition and cooperation among game users so that they can spend more time with their games.

Can Coupon Holding Duration and Message Framing Increase the Effect of Push Notifications on Mobile Coupon Redemption? Evidence from A Randomized Field Experiment

황순기,손재열,박선주,서길수 한국경영정보학회 2023 Asia Pacific Journal of Information Systems Vol.33 No.3

We propose a mobile coupon strategy designed to increase the effect of push notifications on redemption. The proposed strategy recommends that firms deliver mobile coupons with distant expiration dates and remind them through push notifications framed negatively once these expiration dates become imminent, rather than frequently sending coupons with near expiration dates. We test the effectiveness of the proposed strategy using data collected through a randomized field experiment. The findings indicate that push notifications enhance coupon redemption rates for coupons that are held longer by customers than those that are recently received. Additionally, we found that sending negatively framed push notification messages to remind customers of imminent coupon expiration dates further resulted in higher coupon redemption rates. The findings can be employed to offer useful guidance on how to effectively design mobile coupons for achieving higher redemption rates.

모바일 앱 아이콘 컬러가 다운로드 의도에 미치는 영향

최목련,손재열 한국인터넷전자상거래학회 2019 인터넷전자상거래연구 Vol.19 No.6

This paper argues that the proper choice and combination of app icon colors are expected to have a positive impact on users’ app icon preference, which in turn influences favorably their intention to download a mobile app. To empirically test the argument, we first extracted the color combinations that match the user 's emotional image for each of the three mobile app categories: keyboard, photo editing, and dating apps. Based on the extracted colors, we designed four app icons for each of the categories with different color combinations based on a high/low level of matching with users’ emotional image and an analogous/complementary use of colors in app icons. We collected data for empirical testing through a laboratory experiment. The results reveal that a high level of matching with users’ emotional image and an analogous use of colors in app icons positively influence users’ preference for an app, and intention to download their intention to download the app.

플랫폼을 넘어 생태계로: Information Ecology Theory를 활용한 메타버스 산업 생태계연구

신석영,손재열 한국경영정보학회 2023 Information systems review Vol.25 No.4

Recently, amidst the backdrop of the COVID-19 pandemic shifting towards an endemic phase, there has been a rise in discussions and debates about the future of the metaverse. Simultaneously, major metaverse platforms like Roblox have been launching services integrated with generative AI, and Apple's mixed reality hardware, Vision Pro, has been announced, creating new expectations for the metaverse. In this situation where the outlook for the metaverse is divided, it is crucial to diagnose the metaverse from an ecosystem perspective, examine its key ecological features, driving forces for development, and future possibilities for advancement.1) This study utilized Wang's (2021) Information Ecology Theory (IET) framework, which is representative of ecosystem research in the field of Information Systems (IS), to derive the Metaverse Industrial Ecosystem (MIE). The analysis revealed that the MIE consists of four main domains: Tech Landscape, Category Ecosystem, Metaverse Platform, and Product/Service Ecosystem. It was found that the MIE exhibits characteristics such as digital connectivity, the integration of real and virtual worlds, value creation capabilities, and value sharing (Web 3.0). Furthermore, the interactions among the domains within the MIE and the four characteristics of the ecosystem were identified as driving forces for the development of the MIE at an ecosystem level. Additionally, the development of the MIE at an ecosystem level was categorized into three distinct stages: Narrow Ecosystem, Expanded Ecosystem, and Everywhere Ecosystem. It is anticipated that future advancements in related technologies and industries, such as robotics, AI, and 6G, will promote the transition from the current Expanded Ecosystem level of the MIE to an Everywhere Ecosystem level, where the connection between the real and virtual worlds is pervasive. This study provides several implications. Firstly, it offers a foundational theory and analytical framework for ecosystem research, addressing a gap in previous metaverse studies. It also presents various research topics within the metaverse domain. Additionally, it establishes an academic foundation that integrates concept definition research and impact studies, which are key areas in metaverse research. Lastly, referring to the developmental stages and conditions proposed in this study, businesses and governments can explore future metaverse markets and related technologies. They can also consider diverse metaverse business strategies. These implications are expected to guide the exploration of the emerging metaverse market and facilitate the evaluation of various metaverse business strategies.

유튜브 내의 휴리스틱 단서들이 정보검색 콘텐츠 시청의도에 미치는 영향

채지원,손재열 한국경영정보학회 2020 Information systems review Vol.22 No.3

본 연구는 유튜브 이용자들이 정보탐색 중 발견하게 되는 유튜브의 IT 기능들이 휴리스틱 단서로써 컨텐츠에 대한 태도 및 시청 의도에 미치는 영향에 대하여 살펴보고자 하였다. 휴리스틱-체계적 모델(Heuristic-Systematic Model: HSM)에 따르면 사람들은 유용한 정보를 빠르게 선택하여 처리해야 하므로 눈에 띄는 단서인 휴리스틱 단서에 의존하는 경향을 보인다. 본 연구에서는 유튜브 내 존재하는 IT 기능들을 기반으로 발현되는 휴리스틱 단서에 집중하였다. 문헌 연구 및 인터뷰를 기반으로, 콘텐츠에 대한 태도에 영향을 미치는 여러 가지 요소 중에서도 유튜브 내 IT 기능을 통해 발현될 수 있는 세 가지 요인인 사회적 지지, 유튜버의 자기표현, 상호작용성을 도출하여, 해당 요인들을 바탕으로 실험을 진행하였다. 유튜브 속 IT 기능들이 활발히 사용되어 사회적 지지, 유튜버의 자기표현, 상호작용성이 높게 인지되는 경우, 해당 콘텐츠에 대한 태도가 호의적으로 형성되어 시청 의도에 긍정적인 영향을 줄 수 있을 것이라 예상하였다. 데이터 분석 결과, 사용자들은 사회적 지지와 유튜버의 자기표현, 상호작용성을 높게 인지할수록 콘텐츠에 대한 태도를 호의적으로 형성하였으며 이는 시청 의도로까지 이어지는 것을 확인하였다. 본 연구는 유튜브 내 수많은 콘텐츠들 속에서 특정 콘텐츠에 대한 시청을 이끌어내기 위해서 유튜브에서 제공하는 어떠한 IT 기능 요소들을 활용해야 하는지 체계적으로 분류하여 그 역할을 검증함에 의의가 있다.
