In this study, I analyzed the inducing and hindering factors of online shopping malls on browsers in the process of browsing fashion products in online shopping malls. In-depth interviews were conducted by presenting browsing-related questions to women in their 20s and 50s who are interested in browsing fashion products online. Based on the answers of the interviewees, using grounded theory, we analyzed and presented six factors such as price factor, promotion factor, purchase review factor, visual information factor, product information factor, and service factor. Based on inducing and hindering factors to browsing analyzed in this study, a strategy to design a browsing environment in terms of shopping malls was suggested, which will be helpful for practical strategies and marketing in related industries. Basic data will be presented in a thesis on a new type of shopping mall browsing environment related to the rapidly developing information and communication technology. In addition, the negative emotions experienced in relation to the detrimental factors of shopping malls in the browsing process are expected to be helpful in researching fashion product browsing related to consumer psychology.

최근, 지난 2009년 설비제공제도 개선에도 불구하고 여전히 병목설비가 해소되지 않았다는 문제점이 제기되었고, FTTx(Fiber to the x) 기술 보급 확대로 가입자망이 고도화되고 있는 현시점에서, 광케이블의 개방에 대해 재검토가 필요하다고 생각된다. 따라서, 본고에서는 서유럽 국가 및 미국, 일본의 광가입자망 개방에 대한 동향을 살펴보고 국내 설비제공제도 정책에 주는 시사점을 살펴보고자 한다. 유럽은 SMP(Significant Market Power) 사업자에게 NGA(Next Generation Access Network) 구축에 필요한 물리적 망 요소 제공 의무를 권고하는데, 기존의 동선 개방 규제에서 벗어나 광가입자망(FTTx)의 개방(광회선 및 광케이블)까지 명시하고 있다. 미국은 광가입자망 개방을 의무화하지 않고 있는데, 이는 광가입자망 개방 시 투자유인 저해를 보완할 수 있는 제도적 장치가 반드시 필요함을 시사한다. 일본의 사례를 살펴볼 때, 국내에서도 설비제공제도뿐만 아니라 가입자선로 공동활용제도를 통해서 광회선을 개방하는 방식도 검토되어야 함을 시사하고 있다.

Demand for UAM (Urban Air Mobility) aircraft is rapidly increasing in countries around the world due to the problem of traffic congestion in urban areas. Through research and development, various e-VTOL aircraft concepts are being prepared for commercialization, for which airworthiness certification is required, since it is a manned transportation mode for people to board. Factors that pose a fatal threat to the safe operation of UAM aircraft include lightning strikes that can cause damage to structures and disturb the navigation system, as well as icing that impairs flight stability. Since the current UAM aircraft-related lightning and icing certification technology development is insufficient, there is need to develop appropriate airworthiness certification guidelines. In this study, after analyzing the laws and regulations related to aircraft by the FAA and the EASA, we tried to incorporate the lightning and icing certification guidelines for the UAM aircraft. We also analyzed the effects of lightning and icing on UAM aircraft using computational simulation, and presented the basis for establishing practical guidelines for the certification of UAM aircraft to be adopted in the future.
