The position of newspaper has been getting critical, since there are various new digital devices that can embody much information in only one device. Smart devices has risen the possible replacement of newspaper, while they are getting lighter and getting faster access to the information. However, there is lack of study on the application for smart devices, since it is at the early stage of development. In this study, the design method for the effective news application is considered by analyzing not only an external element, the layout design, but also an internal element, the content of it. Then, 20 domestic and foreign news applications were analyzed concentrating on the layout and the contents. Through the observation, I looked into what type of applications that can be deliver messages effectively. After the observation, participants are asked about their impressions and preferences of the applications. A news application for smart devices should not be just a mobile version of newspaper. If so, a news application never be able to leap over authority and popularity of the newspaper. So, it needs constant researches on an effective news application focused on the attribute of the smart devices to develop the news application for the devices.

This study conducted an in-depth case study of bio-health companies in the Chungcheong region to examine the factors influencing the relocation of new industry cluster firms in non-metropolitan areas. Focusing on the experiences and perceptions of key stakeholders within the cluster, which have been relatively overlooked in previous research, this narrative research explored the factors that lead entrepreneurs who initially founded their businesses in non-metropolitan areas to relocate to metropolitan areas as well as the decision-making process involved. Through interviews with 61 key stakeholders within the Chungcheong cluster, it was observed that entrepreneurs receive various benefits from local stakeholders during the initial stages of entrepreneurship. However, as the company enters a phase of significant growth, matters such as securing specialized talent and market accessibility lead them to contemplate relocating to metropolitan areas. Based on case studies of companies that both remained and relocated in the Chungcheong region, this study examines structural drawbacks within non-metropolitan clusters and provides policy implications.

기후변화의 영향으로 자생지에서 고사하고 있는 구상나무 유묘의 대기온도와 연령에 따라 건전도를 파악하고자 지리산 구상나무 실생묘를 대상으로 엽록소형광을 측정하였다. 2020년 7, 8, 9월에 걸쳐 월별 1회씩 연생별(1, 2, 3, 5, 6년생) 20개체를 대상으로 13시, 19시에 개체당 3회 반복 측정하였다. 측정 당시 평균대기온도는 24.6, 26.9, 20.6℃이었으며 잎을 20분간 광을 차단 후 Fv/Fm값을 측정하였다. Fo는 식물이 암적응 된 상태에서 포화광을 조사하기 직전의 형광 초기값이며, Fm은 식물이 암적응 된 상태에서 포화광을 통해 유도된 최대 형광수치를 의미한다. Fv는 Fm-Fo이며, 광화학 반응의 최대 양자수율로 식물의 잎이 광합성을 수행할 수 있는 잠재력을 의미하고 식물의 광합성 활성과 건전도에 대한 지표로 사용된다. 일반적으로 건강한 잎의 Fv/Fm값이 0.8을 기준으로 낮은 값은 광계II의 반응 중심이 손상을 잎은 경우이거나 스트레스 환경에 있는 경우이다. 13시 측정 결과 8월 측정값 중 1년생과 3년생이 0.8 이하로 측정되었고 그 외에는 전부 0.8 보다 높게 나타났다. 19시 측정 결과 8월에 1, 2, 3년생이 0.8 이하로 측정되었으며, 9월에는 1년생의 경우를 제외하고 모두 0.8 보다 높게 나타났다. 1, 2, 3년생은 8월의 높은 온도에 영향을 받아 고산지대에 자생하는 구상나무의 특성상 고온에 대한 스트레스를 받은 것으로 판단되며, 연령이 비교적 높은 5, 6년생은 온도변화에 비교적 안정적인 것으로 나타났다. 따라서 엽록소형광 측정의 결과를 근거로 3년생 이하의 개체는 온도변화에 민감하게 반응하는 반면, 5년생 이상의 개체는 비교적 안정적으로 건전도가 유지된 것으로 판단되었다.

The research focuses on the provincial universities in the western region of China and investigates the research level of 12 provincial universities from 2017 to 2021, considering both static efficiency and dynamic efficiency. The static efficiency is examined using Data Envelopment Analysis (DEA), while the dynamic efficiency is analyzed using the Malmquist model. The analysis results are as follows: the scientific research efficiency of universities in the 12 western provinces is generally not high. Against the background of the "Double First-Class" construction, the overall efficiency of scientific research in universities is showing an increasing trend. The main reason for the increase in scientific research efficiency is the increase in scale efficiency in recent years. The total factor productivity (TFP) of research activities is influenced by the technology progress index and exhibits a pattern of initial increase, followed by a decline, and then an increase again. Research conclusion: Western colleges and universities should reasonably allocate resources for scientific research activities, perfect scientific research mechanisms, improve management standards, promote scientific innovation and corresponding achievements, and ultimately raise the scientific and technological level in western China.

The study aims to comprehend the health needs of multicultural families, identify relevant policies, and explore ways to enhance health information accessibility through Information and Communication Technology (ICT). Employing a qualitative research method, the health status of multicultural families was analyzed through literature review, followed by in-depth interviews. The findings revealed a lower priority given to health policies for multicultural families compared to other governmental sectors, with limited discussion on leveraging ICT for improved accessibility. In-depth interviews highlighted four main themes: "Early experiences in Korean society," "Language barriers in medical facilities," "Unmet healthcare needs for various reasons," and "High demand for health-related services." To safeguard health rights and enhance information accessibility, we recommend strengthening linguistic support in healthcare institutions, implementing government efforts for multicultural families, and designing user-centered ICT platforms.

This study examines IPO underpricing and its interaction with investor attention as one of key factors that can affect post-IPO performance in the short- and long-run. With higher investor attention measured as Google searches around IPO dates, our empirical results show that IT firms are underpriced more severely than non-IT firms. We also demonstrate that investor attention is positively associated with IPO performance in the short-run for both IT and non-IT firms. However, the impact of investor attention is more sustained for IT firms over a longer time horizon when coupled with a high level of underpricing while its impact is neutralized for non-IT firms. Given the unique attributes such as network effects embedded in the IT industry, our findings suggest that IPO underpricing and its interplay with investor attention for IT firms play an important role in shaping long-run performance and ultimately affecting fundamental value.

With the increasing use of E-scooters, there is an urgent need for research into their driving risks because of the rising number of related accidents. Existing theoretical analysis methods are primarily vehicle-centered and do not adequately reflect the lightweight and compact characteristics of E-scooters. This study was conducted on real roads to analyze the risk and stable speeds of drivers on longitudinal slopes, considering the unique attributes of E-scooters. The risk speed on slopes was, on average, 21 km/h, with the initial risk speed decreasing as the slope became steeper. The stable speed was determined to be an average of 17 km/h, except on slopes of 1-2%, which presented a relatively low risk. These results are expected to contribute to the academic foundation for policies aimed at reducing the top speed of personal mobility, as is currently being promoted in Korea.

This study examines whether startup firms start with the resources they already have and expand the resources they can mobilize in the process of business management (Effectuation Model) using public data provided by the government. The results of the study show that the Effectuation Model can partially explain the behavior of early-stage startup firms. Therefore, in terms of policy implications based on these findings, government policies for entrepreneurship should not be based on the selection of companies based on sophisticated business models and hypothetical profit models, but rather on a system that actively supports entrepreneurship in areas that are challenging, even if they seem somewhat reckless at the moment, or that best match the entrepreneur's knowledge. Next, in order to actively spread entrepreneurship, it is necessary to spread business history or entrepreneurial experience. To this end, it is necessary to drastically change the current financial system for startups, where the founder bears all the financial risk, and to more actively consider ways to reduce the risk of startups by allowing society and the financial system to share some of the risk of startups.
