An increasing number of mountaineers are recently creating diverse consumer needs for mountaineering garments, thereby leading to a production of smart mountaineering garments with diverse-functions. Smart mountaineering garments are increasingly adding to comfort and safety, boosting their market size. This study researched on the Technology Acceptance Model (TAM) to examine factors that influence the intention of consumers to purchase buy mountaineering garments. For that purpose, 641 people aged 20-61 years who experienced in mountaineering were surveyed online. An extended TAM was designed by adding new variables such as fashion involvement and garment involvement associated with the characteristics of clothing products to the variables such as self-efficacy sense, technological innovativeness, perceived enjoyment. The findings of the study suggested that self-efficacy sense influenced perceived usefulness, perceived easiness of use, and perceived enjoyment, while garment involvement and fashion involvement influenced the perceived easiness of use and the perceived usefulness, respectively. Also, the perceived easiness of use influenced perceived usefulness and perceived enjoyment, while the perceived usefulness and perceived enjoyment directly influenced the intention of purchase. Based on the findings of this research, this study seeks to determine factors variables of smart garments purchase intention, and to explore measures to enhance such purchase intention, thereby offering working implications for developing smart mountaineering garments.

The purpose of this study is to empirically identify the process of technology acceptance of the metaverse, a virtual world-based platform that has attracted attention due to the 4th industrial revolution and the COVID-19 pandemic. The technology acceptance model (TAM) was used to identify factors affecting the use of the metaverse platforms and to analyze the causal relationship among these factors. For research, a survey was conducted on ordinary adult men and women and was analyzed using a structural equation model. The study found that perceived pleasure, interactivity, self-efficacy, and social influence had a positive effect on perceived ease-of-use. Interactivity and social influence had a statistically significant effect on perceived usefulness. The relationship between perceived ease-of-use and perceived usefulness was not statistically significant, but both perceived ease-of-use and perceived usefulness had a significant effect on positively forming attitudes toward metaverse. Lastly, favorable attitudes toward the metaverse platform had a positive effect on the intention to continue using it. Through this study, it was possible to identify the factors affecting the intention to use the metaverse and to confirm the causal relationship between the factors. A deeper understanding of users may be obtained in future if the research subject can be expanded and investigated with various factors.

최근 온라인 게임 시장이 급속하게 성장하고 있다. 온라인 게임은 컴퓨터 게임의 장르 중에 상당히 큰 비중을 차지하고 있으며, 많은 사용자들은 온라인 게임을 매일 즐기고 있다. 온라인 게임 시장이 커지면서, 온라인 게임 아이템의 거래 시장 역시 성장하고 있으며, 온라인 게임 아이템은 게임 안에서 거래가 이루어질 뿐만 아니라 게임 밖에서도 실제 화폐를 통해 거래되고 있다. 게임 아이템에 대한 경매 사이트가 국내뿐만 아니라 외국에도 존재하여 활발히 거래가 이루어 지고 있으며, 2004년에는 게임 아이템의 구매를 위해서 최대 8억 8000만 달러에 이르는 실제 화폐가 지불될 정도로 게임 아이템의 거래 시장은 거대하다. 이렇게 규모가 커진 게임 아이템 거래 시장은 학술적으로, 실용적으로 많은 중요성을 갖는다. 그러나 온라인 게임 아이템 거래에 대한 실증적인 연구는 많지 않다. 몇몇 온라인 게임 아이템 거래에 대한 연구는 게임 아이템의 권리를 중심으로 연구가 되었으며, 게임에 대한 많은 연구는 게임 아이템보다는 몬스터와 싸우는 것이나 게임 캐릭터를 만드는 것과 같은 게임 플레잉 설계에 집중하고 있다. 또한 전자 상거래 분야에서는 사용자들이 거래를 통해 최대한의 이윤을 얻기 위할 것이라는, 즉 외적 동기를 가지고 있을 것이라는 가정을 바탕으로 거래의 효율성과 거래 비용에 초점을 맞추어 연구가 진행되었다. 그러나 온라인 게임 아이템은 실용적인 성격뿐만 아니라 유희적 성격을 가지고 있기 때문에 온라인 게임 아이템 거래에서 사용자는 외적 동기뿐만 아니라 내적 동기도 함께 가지게 된다. 본 연구는 거래 비용이론과 몰입, 그리고 재미와 관련된 이론을 바탕으로, 온라인 게임 아이템의 거래 방식이 사용자의 지각된 재미와 사용자가 느끼는 거래비용에 미치는 영향을 실험 방법론을 통해 실증적으로 검증하였다. 본 연구의 결과, 거래에서 내적 동기를 가진 사용자는 게임 아이템 거래 의도에 지각된 재미가 거래 비용에 비해 더 많은 영향을 미쳤으며, 외적 동기를 가진 사용자는 게임 아이템 거래 의도에 지각된 거래비용이 지각된 재미에 비해 더 많은 영향을 미쳤다. 본 연구의 결과는 과거 대부분의 관련 연구가 거래 방법의 유용성만을 강조해왔던 것과는 달리, 거래 자체의 재미와 즐거움, 그리고 거래에 대한 몰입 등의 감성적 측면을 고려함으로써 거래 비용 이론을 확장했다는 데 이론적 의의가 있을 것이다. 또한 실용적 측면에서 게임 아이템 거래 방식을 어떻게 설정해야 사용자들에게 유용성과 더불어 재미를 제공해 줄 수 있는지에 대한 실질적인 가이드라인을 제시할 수 있을 것이다.
