This study analyzed the driving factors of the enlargement process of ASEAN member countries from 1995 to 1999. The main research question is how can it explain the difference in the decision-making timing of countries wishing to join regional cooperation. This study focuses on why the countries that did not join ASEAN in the early years of ASEAN membership, since the mid - 1990s, and why they joined the different periods since the end of the Cold War. To this end, this study analyzed the accession process of Vietnam, Laos, Myanmar and Cambodia. The main argument of the study is that there is a time gap in the accession of ASEAN, but ultimately the regional cooperation is used to secure the legitimacy of maintaining the system. Most of the previous studies on the expansion of regional cooperation have discussed the expansion of regional cooperation in terms of macroeconomic changes such as international system change. However, this study focuses on the domestic political and economic situation of motivating individual member countries to join regional cooperation and this is complemented by a micro approach.

As the number of successful design innovation product cases in business increases, interest in design innovation is increasing. This study aims to examine how the design innovation (functionality, ergonomics, aesthetics) of Bluetooth speaker products affects the customer's preference and purchase intention. It proposes a research model through rational behavior theory (TRA) and technology acceptance model (TAM) for empirical research. The questionnaire was composed of questions to understand the influence of design innovation, favorability, and purchase intention. As a result of the study, functionality, ergonomics, and aesthetics influenced product preference and purchase intention. In order for the innovative product of Bluetooth speaker design to be accepted in the early market, it is most important to form a positive attitude toward favorability centering on function and aesthetics. Favorability is a factor that has the most decisive influence on the purchase intention of design innovation products, and companies must discover and reinforce various factors that positively affect the preference.

Development of 5th generation mobile telecommunication technology is visualizing ideal hyper-connected social information and communication technology (ICT). In particular, virtual reality (VR) technology is at the starting point for new expansion and leaps. This work defines virtual reality as media in this context and collects and analyzes discourse on its scalability around space and communication theory. We first elaborated the concept, starting with the early discussions of the virtual reality concept in 1990, and discussed the relationship between the physical world and digital information, expression and interaction immersion as a medium, simulation, art creation theory, and finally evolutionary development. In conclusion, beyond the discourse on the technology of virtual reality, academic subjects were required to have theoretical frameworks on cognitive science, neuroscience, social science, and humanities issues (ethics, personality, etc.) for the development and evolution of virtual reality. In other words, it is time for the evolution of virtual reality to be discussed, which can be moved beyond.

전 세계적으로 지구 온난화로 인해 발생한 가뭄은 사회적, 경제적, 환경적으로 막대한 피해를 야기하고 있다. 국내의 경우, 2022년부터 현재까지 지속되고 있는 가뭄 상황은 강수의 지역적 편차로 인해 남부 지역 중심으로 극심한 피해가 발생하였다. 남부 지역의 주요 용수공급원인 영산강, 섬진강권역의 용수 공급율은 예년의 57%(3.8억 톤)에 불과하며, 일부 도서·산간 지역은 용수공급이 제한되는 현상까지 발생하였다. 이러한 가뭄 피해를 대비하기 위해 초기에 모니터링을 통한 선제적 대응 방안을 구축해야 한다. 가뭄 모니터링의 경우 미계측 지역에 대한 모니터링 방법으로 주기적이고 균질한 자료를 제공 받을 수 있는 위성영상을 활용한 연구가 수행되고 있다. 가뭄을 정량적으로 분석하고 판단하기 위해 가뭄지수를 활용하고 있으며, 대표적인 가뭄지수는 지상 관측강수량자료를 활용한 확률분포 기반의 표준강수지수 (Standardized Precipitation Index, SPI)와 강수 및 기온의 변동성이 포함된 표준강수증발산지수 (Standardized Precipitation Evapotranspiration Index, SPEI)가 있으며, 위성영상 자료를 활용한 가뭄지수인 증발스트레스지수(Evaporative Stress Index, ESI) 등이 있다. 본 연구에서는 강수와 기온을 고려한 가뭄지수인SPEI와 위성영상 기반의 가뭄지수인 ESI를 활용하여 2022년 남부 지역의 가뭄 사상을 중심으로 지표별 시공간적 변화를 분석하고자 한다. SPEI의 경우 기상관측소 지점자료의 기온과 강수량을 활용하였으며, Terra 위성의 MODIS (Moderate Resolution Imaging Spectroradiometer) 센서에서 제공되는 위성영상자료를 활용한 ESI는 미계측 지역에 대한 가뭄 판단을 위해 시·군별로 세분화하여 산정하였다.

The purpose of this study is to analyze NSSI (Non-suicidal Self-Injury) and upcoming papers to review research achievements and endpoints and current problems. Analysis data necessary for the study were collected through the classification procedure as domestic suspension during the mandatory period related to self-harm from 2010 to the present. As a result of analysis according to classification categories (general characteristics, study subjects, research variables, program utilization), first, domestic studies related to non-suicidal self-harm increased steadily through 2019 and 2022 after increasing in 2017 (three articles) showing shape. Second, changes in the characteristics of the research subjects began to appear. If previous studies had mainly focused on adolescents who experienced self-harm, it was expanded to early adulthood (college students), and the subjects of the study diversified to include those who had experienced self-harm cessation, counselors, and parents. Third, various research methods began to appear. Compared to 2017, when quantitative research was active, research was conducted that applied various qualitative research methods (narrative, phenomenology, grounded theory, meta-analysis, case study). Finally, discussion of the research results and suggestions for future research were added.
