Recently, as personal information utilization devices such as IoT, artificial intelligence, and wearable devices that focus on the individual have spread, privacy violations are also increasing. However, the privacy paradox of providing personal information to enjoy services while worrying is getting stronger. However, there are still preliminary studies on this. In this study, an intelligent home camera based on IoT technology was selected as a research object, and whether privacy paradox exists in the IoT environment, including smart home camera, was studied. To this end, the effect of perceived usefulness, a benefit factor of smart home camera use, and privacy concern, a risk factor, on intention to use was verified. In addition, it was investigated whether the relationship between privacy concerns and intention to use differs according to the presence or absence of use experience. In order to verify the research model, a survey was conducted with people with and without experience in using smart home cameras, and a total of 298 data samples were used for statistical analysis. As a result of the analysis, it was found that both perceived usefulness and privacy concerns had a positive effect on the intention to use, proving that privacy paradox exists in the IoT-based smart home camera environment. In addition, by analyzing the fact that privacy concerns have different effects on usage intentions depending on the user experience, it was verified that those with experience have a strong privacy paradox and those without experience have a weak privacy paradox. This study is meaningful because it seeks strategic implications to improve service and business performance by understanding the relationship between privacy attitudes and behaviors of IoT service providers, including smart home cameras.

This research note aims to provide a critical understanding of "tourist stupidity" and "exclusiveness" within the smart tourism domain and to propose a corresponding qualitative research agenda. It argues that qualitative research methodologies are too infrequently applied, leading to a paradox evident in smart tourism studies. Accordingly, it suggests that embracing a qualitative perspective is essential to diversify the scholarly discourse and promote advanced inquiry in the field of smart tourism. It further seeks to contribute to ongoing debates by focusing on umbrella terms, such as "tourist stupidity" and "exclusiveness," for a more nuanced and holistic understanding of smart tourism and proposes a research agenda that advocates a re-evaluation of qualitative approaches.

모바일 메신저는 20세기 초반의 전화기, 1950~60년대의 텔레비전과 마찬가지로 사람들의 삶에 큰 변화를 유발하였다. 하지만 많은 연구자들은 모바일 메신저가 공동체의 삶과 사회적 관계를 향상시키는지 혹은 악화시키는지에 대해 갑론을박을 벌이고 있다. 본 연구는 국내 두 대학의 155명의 대학생들을 대상으로 모바일 메신저의 사용과 사용에 따른 영향(외로움)에 대해 설문조사하였다. 설문대상자들은 모두 모바일 메신저를 능숙하게 사용할 수 있으며, 자주 사용하는 대상자들이다. 연구결과 지나친 모바일 메신저의 사용은 자기 주변의 사람들과의 의사소통을 감소시키는 것으로 나타났으며, 이는 또한 외로움에 영향을 미치는 것으로 나타났다.

모바일 인스턴트 메신저 50~60년대 TV나 20세기 초 전화만큼이나 우리의 삶을 변화시키고 있다. 따라서 많은 학자들은 모바일 인스턴트 메신저가 우리의 공동체 생활과 사회적 관계에서의 참여를 향상시키는지 아니면 해를 입히고 있는지에 대해 궁금증을 제시하고 있다. 이를 위해 본 연구에서는 2개 대학의 155명의 참여자를 대상으로 자신이 소유한 모바일 인스턴트 메신저가 외로움에 미치는 영향을 탐색해보고자 하였다. 연구결과, 높은 모바일 인스턴트 메신저 사용은 타인과의 의사소통을 감소시키고 결국 외로움을 증가시키는 것으로 나타났다.

Soundtrack dissonance, which appears in the background music of a movie scene, is a phenomenon of using songs or compositions that contrast with the general sentiment of the situation. A sad scene usually uses a slow tempo of sad music to match the mood of the scene. However, sometimes, in order to play background music that follows a depressing, sad, or anxious scene, there is a case of inserting music with an opposite atmosphere such as bright music, exciting music, fast-tempo music, or magnificent music. The method of presenting music that is contrary to the mood of the scene is a kind of psychological technique that inflicts a kind of mental shock on the audience and makes them remember a particular situation. In this study, we have investigated the meaning coming from scenes and Soundtrack Dissonance in movies, in order to understand the role that music and images play.

A new algorithm is proposed to determine optimal accelerometer locations (OAL) when a structure is identified by frequency domain system identification (SI) method. As a result, a guideline is presented for selecting OAL which can reflect modal response of a structure properly. The guideline is to provide a minimum number of necessary accelerometers with the variation in the number of measurable target modes. To determine OAL for SI applications effectively, the modal sensitivity effective independence distribution vector (MS-EIDV) is developed with the likelihood function of measurements. By maximizing the likelihood of the occurrence of the measurements relative to the predictions, Fisher Information Matrix (FIM) is derived as a function of mode shape sensitivity. This paper also proposes a statistical approach in determining the structural parameters with a presumed parameter error which reflects the epistemic paradox between the determination of OAL and the application of a SI scheme. Numerical simulations have been carried out to examine the proposed OAL algorithm. A two-span multi-girder bridge and a two-span truss bridge were used for the simulation studies. To overcome a rank deficiency frequently occurred in inverting a FIM, the singular value decomposition scheme has been applied.
