The purpose of this study is to analyze the structural patterns of international student inflow and predict future trends using the ARIMA model. By employing data from 2010 to 2023 on international students in South Korea, the study ensures stationarity through differencing and identifies the optimal ARIMA(2, 1, 1) configuration via ACF and PACF analyses. Results highlight the significant impact of external shocks, such as the COVID-19 pandemic, on student enrollment trends, followed by a gradual recovery. The study also identifies key factors influencing student attraction and retention, including nationality, gender, degree type, language proficiency, and educational satisfaction. Moreover, the research incorporates multivariate analysis, offering insights into the role of tailored support programs such as language education, cultural adaptation services, and academic assistance. These findings provide practical recommendations for enhancing recruitment strategies and underline South Korea's potential to strengthen its position as a global educational hub through data-driven policymaking and strategic planning..
The decrease in local population breaks the balance with the economic development of the region, fails to realize decentralization and balanced development, and eventually approaches the crisis of local extinction. The main causes of the population decline in the provinces were the natural decrease due to the low fertility rate and population aging, and the larger factor, the social decrease (population outflow). In the Special Self-Governing Province, it is necessary to break away from the policy practice of the central government and actively prepare policy measures to respond to local extinction by using its own special authority and position. Since the policy establishment of the central government related to the population decline crisis, such as the 「Basic Act on Low Fertility and Aging Society」 in 2006, was promoted in a uniform way, there are many problems that do not properly reflect the characteristics of each local government and the situation at the site. Accordingly, five measures are proposed for the Special Self-Governing Province to establish policy measures that are sustainable and reflect regional specialization.
The urban regeneration project started under the Park Geun-hye administration and was promoted more heavily as a New Deal project under the Moon Jae-in administration. However, as the urban regeneration project progressed, problems arose that residents could not feel due to poor implementation performance and low execution ability. Accordingly, in this study, in order to establish and achieve the goals of the urban regeneration revitalization plan, a management system and performance indicators for monitoring, evaluation, and feedback are presented to systematically and comprehensively manage everything from plan establishment to performance and effect derivation, and a resident satisfaction survey to measure performance. We conducted an investigation. In order to accurately measure performance, the ‘Comprehensive Performance Index’ presented by the central government was used as a common indicator, and the ‘Local Government Performance Index’ was comprehensively analyzed and used as an auxiliary indicator. In this study, research was conducted targeting the ‘Jeonju Station Area Urban Regeneration Area’, which is currently under construction, to select indicators for performance measurement, and practical data was presented in relation to the research method.
If a home tenant does not receive a deposit back after the contract is terminated, a lease deposit return guarantee system is in effect to protect it, but there are still many aspects to be improved. In this study, we would like to present the direction of improvement of the lease deposit return guarantee system as follows. First, when a tenant applies for guarantee insurance, there is still a lot of time delay. In the future, if the tenant applies for a lease registration order, and if the tenant applies for guarantee insurance, the guarantee agency must check only the necessary matters such as the house's brightness and payment in advance. Second, in signing up for guarantee insurance, the limitation of the deposit should be deleted so that all tenants can use this system if necessary. Third, if there is a change in the size and target of application to improve the system, it should be applied only to new leases, and the previous matters should be applied to renewed leases. This is because if it is also applied to renewed leases, there may be many cases in which guarantee insurance cannot be subscribed while being renewed.
In order to continuously generate revenue for cooperatives, the Ministry of Land, Infrastructure and Transport has presented business models by sector and type, but unlike the direction of self-sustaining businesses and the will of residents, most of them are public facility management and public service projects, making sustainable business difficult. situation. In order to solve this, it is necessary to prepare and utilize the space that can be owned by the concept of citizen property through institutional and legal improvements so that the village management social cooperative can purchase assets within the urban regeneration project site. It is necessary to recognize that it is a citizen asset and inspire a sense of ownership so that a successful urban regeneration project can continue even after the regeneration project is completed, so the village management social cooperative must take the lead in investing in local regeneration that guarantees asset investment and citizen participation. In addition, by nurturing experts (citizen asset managers) for citizen asset development and granting a certification system, it is required to act as a participation leader for the vitalization of village management social cooperatives. It was suggested that it should be reflected and proceeded.
Compared to the rent of the house, it is difficult to grasp objective information. Among them, the purpose of this study is to analyze the determinants of monthly rent for small and medium-sized office buildings with stronger individuality. The data used in this study are data from 288 small and medium-sized office buildings actually traded in Gangnam-gu, Seocho-gu, and Songpa-gu in Seoul. According to the analysis results, the factor that most influences the monthly rent decision of small and medium-sized office buildings was the elapsed life of the building. Next, the number of basement floors, management costs, official land prices, parking spaces, deposits, number of elevators, and distance to the subway station were found to be valid factors. Unlike previous studies that converted the deposit into monthly rent in the determinants of occupation cost of office buildings, this study analyzed the determinants of pure monthly rent for small and medium office buildings. This is a study to analyze only the determinants of monthly rent by reducing the error generated by converting the deposit to monthly rent in the event of a rapid interest rate hike.
Real estate Lease fraud refers, to fraudulent activities such as not actually renting the relevant real estate or disadvantaging the tenant in violation, of the terms of the JEONSE contract after receiving a JEONSE deposit while signing a JEONSE contract. If you don't actually rent, a property with a lease deposit, the tenant will not receive the deposit back and will have difficulty finding a place to live. Such real estate Lease fraud is recognized as a social problem, due to the problem of damaging the stability of the real estate market and infringing on the rights, and interests of tenants. Real estate Lease fraud is emerging as a social problem that undermines the, stability of the real estate market and violates the rights and interests of tenants. To solve this problem, institutional improvement is needed to prevent, real estate Lease fraud. In this paper, we would like to present institutional improvement measures to, solve these problems through the analysis of the concept and type of real estate Lease fraud and the causes, of real estate Lease fraud. In addition, through overseas case analysis, we would like, to investigate the operation and effectiveness of the real estate Lease fraud prevention system to find, ways applicable to Korea. To this end, the introduction will briefly explain the research background, research purpose, and research method, and then deal with, the concept and type of real estate lease, fraud, cause analysis, and overseas case analysis.
Abstract Salmonellosis is a major global public health issue; its most common infection, gastroenteritis, accounts for approximately 90 million illnesses and 150,000 mortalities per year. Eradicating salmonellosis requires surveillance, prevention and treatment, entailing large expenditures. However, it is difficult to control Salmonella transmission because it occurs via multiple routes; exotic reptiles are a reservoir of Salmonella and comprise one such route. As the popularity of exotic pets and animal exhibition has increased, human encounters with reptiles have also increased. As a result, reptile‐associated salmonellosis (RAS) has been recognized as an emerging disease. The development of antimicrobial resistance in RAS‐causing Salmonella sp. requires alternatives to antibiotics. In this study, bacteriophages have been established as an alternative to antibiotics because only target bacteria are lysed; thus, they are promising biocontrol agents. Here, bacteriophage pSal‐SNUABM‐02, which infects and lyses reptile Salmonella isolates, was isolated and characterized. The morphology, host range, growth traits and stability of the phage were investigated. The phage was assigned to Myoviridae and was stable in the following conditions: pH 5–9, 4–37°C, and ultravioletA/ultravioletB (UVA/UVB) exposure. Salmonella clearance efficacy was tested using planktonic cell lysis activity and biofilm degradation on polystyrene 96‐well plates and reptile skin fragments. The phage exhibited vigorous lysis activity against planktonic cells. In in vitro biofilm degradation tests on reptile skin and polystyrene plates, both low‐ and high‐concentration phage treatments lowered bacterial cell viability by approximately 2.5–3 log colony‐forming units and also decreased biomass. Thus, bacteriophages are a promising alternative to antibiotics for the prevention and eradication of RAS.
