Purpose: The purpose of this study was to show current states of domestic Precision Guided Missile(PGM) by analyzing Live-fire test results using general methods to get the Confidence Levels. Methods: Live-fire test results were used to get Confidence Levels of PGM. The Confidence Levels were derived by two general methods. The first method was Binomial distribution and second was convergence of Hypergeometric distribution and Bayes' rule. Results: The results of this study are as follows; The more Live-fire tests of PGM are performed, the higher Confidence Level of PGM will be estimated. And the number of Live-fire tests are related to a unit price of PGM. This results means that the increase of live-fire test, which is useful data for preparation and evaluation of Development Tests / Operation Tests for PGMs, is only way to enhance the Confidence Levels of each PGMs. Conclusion: This study shows the relationship between the Live-fire tests and Confidence Levels of PGMs and it will be used on Live-fire Test & Evaluation of PGMs for reference.

Objectives: The purpose of this study was to investigate the effect of exterior vascular laser irradiation therapy by live blood analysis. Methods: We analysed the changing forms of the live blood sample with a microscope before and after exterior vascular laser irradiation therapy of the blood. Results: Rouleau of red cells, erythrocyte aggregation of red cells, thrombocyte aggregation, uric acid crystals, red crystals, and protoplasts in blood were decreased significantly after exterior vascular laser irradiation therapy. Conclusions: This study suggests that exterior vascular laser irradiation will have positive effects in eliminating various effete matters in blood and will have efficacy in the treatment and prevention of cardiovascular system disorders and hyperlipidemia, caused by effete matters, or numbness and arthralgia caused by blood stagnancy and blood circulation disorder.

Purpose: Market competition in the fashion industry is intensifying, pushing brands to strive for consumer preference and market leadership. Mobile fashion applications have emerged as key distribution channels, with live streaming being a common feature for product distribution and consumer loyalty. Therefore, this study will analyze the loyalty model in live streaming on mobile fashion applications by integrating the quality loyalty model, parasocial relationships, and uses and gratifications (U&G) theory. Research design, data and methodology: Data were collected from a survey of 427 respondents who are customers of a fashion product that had been purchased through live streaming on a mobile fashion application and processed using the PLS-SEM method Results: The results of the study show that the live streamer and product quality significantly influence satisfaction and loyalty. Conversely, AR content and live streaming content do not directly influence loyalty but have an indirect effect through satisfaction Conclusions: this study is the first to model loyalty in mobile fashion applications by integrating the quality loyalty model, parasocial relationship, and U&G theory.

라이브커머스 시장의 성장은 스마트폰만 있으면 언제, 어디서나, 편리하고 간단하게 라이브커머스를 시작할 수 있다. 스마트폰 서비스 이용은 지속적인 커뮤니케이션을 제공하며, 심리적 애착을 느끼면서 이용하게 되고, 더 나아가 심리적 애착과 소비자 자신과의 자아일치, 자아정체성까지 연결된다. 본 연구는 라이브커머스를 이용하는 소비자의 동기와 지각에 초점을 두고 살펴보고자 한다. 즉, 소비자의 개인적, 심리적 특성으로 조절초점성향과 자아효능감(self-efficacy)의 조절효과를 통해 서비스애착과의 관계를 살펴보려 한다. 다시 말해, 소비자의 동기와 목표에 따라 소비자의 행동 방향을 결정하게 되는 조절초점(regulatory focus)성향이 라이브커머스의 서비스애착에 영향을 미치고. 주어진 상황이나 과업에서 원하는 결과를 위해 스스로 계획하고 실행하여 목표를 달성할 수 있다는 개인적인 자신감 및 확신과 신념인 자아효능감(self-efficacy)이 이러한 관계를 조절할 것으로 본다. 분석결과, 예방초점을 높게 지각하는 소비자들은 부정적인 결과를 회피하고, 안전과 의무를 추구하는 경향이 강할수록, 개인적인 자신감과 신념인 자아효능감이 상쇄시켜 라이브커머스의 서비스에 대한 애착을 더 강하게 형성시켰다. 라이브커머스 서비스 이용 시, 정보획득에 대해 유익하다고 지각할수록, 자신의 신념인 자아효능감이 높아지므로 안전추구성향과 부정적 결과를 회피하려는 예방초점성향의 소비자들에게 인지적 경험뿐 아니라 감정적 경험인 서비스애착이 강하게 형성되는 것이다. 본 연구를 통해 라이브커머스의 서비스 이용에 대한 소비자의 심리적 행동을 이해하고, 이를 기반으로 라이브커머스에 진입하려는 기업 및 소상공인들에게 운영전략 및 관리에 도움이 되리라 본다.

This study empirically verified the effect of the characteristics of live commerce on consumer trust and purchase intention. An online survey was conducted targeting adult women in their 20s and 30s who watched videos relating to fashion products on the NAVER shopping live channel; 281 questionnaires were analyzed using the IBM SPSS statistics 23 and AMOS 21 software packages. Consequently, the four factors of interactivity, attractiveness, price discount, and playfulness were identified from the data as characteristics of live commerce. Whereas interactivity and playfulness positively affected trust in both the seller and the product, attractiveness did nor significantly affect trust in the seller and the product. Furthermore, price discount had a significant positive effect only on trust in the seller and had no significant effect on trust in the product. In addition, trust in both the seller and the product had a significant positive effect on consumers' purchase intention; in particular, trust in the seller had a greater influence on consumers' purchase intention than trust in the product did. Research on the characteristics of live commerce can contribute to extend the theorical framework of live commerce research. Finally, fashion companies using live commerce channels will be able to develop live commerce channels that can elicit positive consumer perceptions based on the results of this study.
