This research was conducted to find out price change of education service. Consumer Price Index annual series data in Korea National Statistical office from 1990 to 2004 were used for analysis. First, education price indexes showed an average annual increase of 7.3% during the last 15 years (1990-2004), marking the highest increase among items in the CPI basket. The average annual increase in tuition fees and other fees, expenditure classes of education price. has been 7.5% and 6.0%, respectively. Secondly, an average increase in tuition fees for two-year college was higher, followed by tuition fees for kindergarten, private four-year college, national four-year college and secondary schools. An average increase in primary school textbook costs was higher in the category of 'other fees' followed by junior high school textbook costs, junior high school supplementary book costs and home delivery supplementary book costs Thirdly, there were no differences in price changes of secondary school textbooks, junior high school supplementary books, high school supplementary books among 16 locations. An average increase in after-school education (selective subjects) for college entrance examination was higher in Gwangju but lower in Seoul, compared with other cities. An average of 7% difference was seen annually among regions. When the year 2000 was considered as 100, the most significant gains were seen in Kwangju at 80% and Gangwon at 57%. An increase in after-school education (all subjects) for college entrance examination was higher in South Cholla Province but lower in North Gyeongsang Province. An increase in after-school education (all subjects) for college entrance examination was higher in South Cholla Province but lower in North Gyeongsang Province. An average of 7% difference was seen annually in the annual increase. When the year 2000 was considered 100, most significant increase was seen in Busan and South Gyeongsang Province at 37% and Jeju Island at 34%.

The purpose of this study is to analyze the effect of the educational environment on the prices of studio apartments, known as officetels, in Korea. Since the revision of relevant laws in 2010, they have served as substitutes for residential purposes in areas suffering from housing shortage, especially where the educational environment is a significant factor. To assess the relation between the educational environment and rental rates, the hedonic price model and artificial neural networks were implemented. The national assessment of the academic performance of middle and high schools that were closest to each officetel, and the ratio of students going to special-purpose schools and private high schools were considered as independent variables. Research findings indicated that the positive effect of the dependent variable increased as the value of educational environment-related variables increased. This result could be utilized as a functional index for housing providers after considering educational environments.

This study began with the fact that the relationship between eductional environments and housing price needs to be understood in the context of the structuring of socio-spatial disparity. In other words, this paper focuses on the fact that the eduction with public features and functions plays a role of housing price determination and the rising price is privatized only to cause socio-spatial inequality. The study first examines how the education factors determine the housing price and cause increasing social inequality in Seoul at the macro level. It also carried out more detailed quantitative analysis on the relationship between educational environment factors and housing price with the case study of Yangcheon-gu, Seoul. This study found out that the close relationship between educational environment, housing price and social disparity at various spatial scales. It also figured out the the educational environment factors play an important role of housing price determination as much as material features per se. This means that the relationship between education, housing price and inequality needs to be dealt with not just socially but also in spatial perspective. In addition, the housing price determination is not just technical research but an social science issue in the context of rising socio-spatial disparity. This study is of only significance as a starting point of promising related researches in the future and much more efforts will be needed.

Apartments constitute 64% of the housing type composition, representing the highest proportion among housing types. This proportion has been increasing annually. Given this trend, apartment prices are likely to have a significant impact on the national economy and people's livelihoods. This study examines the impact of the recent development of Seodaegu Station on the surrounding apartment market, with a specific focus on the effects of the educational environment. To this end, we conduct empirical analysis employing a hedonic price model and spatial autocorrelation analysis, based on actual transaction price data from the Ministry of Land, Infrastructure, and Transport. The study revealed three key findings: first, the development of Seodaegu Station positively impacted apartment prices. Second, this positive effect increases with the proximity to Seodaegu Station. Third, the enhancement of the educational environment nearby the Seodaegu Station development also positively influenced apartment prices. This study aims to serve as baseline research output for the public management of future metropolitan transportation facility development projects and for predicting apartment price trends.

스팟 인스턴스(Spot instance)는 클라우드 환경에서 사용자가 제시한 입찰 가격으로 클라우드 내의 자원을 이용하여 작업을 수행할 수 있게 하는 새로운 방식이다. 사용자는 자신의 입찰 금액이 클라우드 내의 스팟 인스턴스 가격을 초과하는 한 인스턴스를 실행할 수 있다. 그러나 입찰 가격이 스팟 가격보다 낮다면 작업 실패가 발생하고, 이로 인해 작업 완료 시간은 지연되며 서비스 품질은 저하된다. 이 문제를 해결하기 위해, 본 논문에서는 스팟 인스턴스에서 사용자 비드가 초과되어 작업 수행이 중지된 VM에 대하여 체크포인트 기법과 VM 이주(migration) 기법을 이용함으로써 작업 대기 시간을 줄이는 방법을 제안한다. 이는 작업 중인 스팟 인스턴스에서 작업 실패가 발생할 경우 다른 인스턴스로 이주하여 작업을 재수행하는 기법이다. 실험 결과는 제안하는 VM 이주 기법이 작업을 수행할 수 있는 스팟 인스턴스의 가용성을 증가시킬 수 있음을 보여준다.

Korean households' expenditures on the eating -out have been steadily increasing except for the foreign exchange crisis period. This paper aimed to examine the eating-out expenditures of salary and wage earners's households by educational attainment of household head. We modeled the demand function of eating-out in terms of income and price, examining the responsiveness of eating-out demand to changes in income and price using econometric methods such as regression, rolling regression and impulse response. This paper showed that coefficients of income and price tended to decrease as the income rises in the long-run. Specifically, the higher the educational attainment of household head is, the smaller the coefficients of income and price we. The impulse response analysis also indicated that while price shocks decreased the demand for eating-out, income shocks tended to increase tile demand for eating-out in all the educational attainments. Furthermore income shocks were much greater and last longer than price shocks at all educational attainments of household heads.

클라우드 환경에서 스팟 인스턴스(spot instance)는 사용자가 제시한 입찰 가격으로 클라우드 내의 자원을 활용하도록 해 준다. 그러나 사용자의 입찰 가격이 클라우드 자원 가격보다 높으면 작업 실패가 발생하고 이로 인해 작업 완료 시간의 지연과 서비스 품질의 저하를 야기한다. 이 문제에 효과적으로 대처하기 위해, 본 논문에서는 시간 문턱치 기반의 검사점(time threshold-based checkpointing) 기법을 제안하고, 시뮬레이션을 통하여 작업 수행 시간과 비용 절감 관점에서 기존 기법과 비교 분석한다.

Objectives: The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice. Methods: A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis. Results: The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education. Conclusions: Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.
