본 연구는 가구의 사교육비 지출에 있어서 공간적 맥락이 중요하게 다루어져야하며, 사교육비에 관한 정책을 위해서는 지역의 교육환경과 여건을 고려해야 할 필요가 있음을 실증하고자 하였다. 이를 위해 분위회귀모형(quantile regression model)을 이용하여 사교육비 지출이 높은 계층에 영향을 주는 '지역 교육열 요인'의 영향력이, 상대적으로 사교육비 지출이 낮은 계층과는 매우 다르다는 가설을 검증하였다. 분석 결과, 수도권 거주여부가 사교육비 증가액에 미치는 영향력은 사교육비 지출 분위가 높을수록 크게 나타나는 것으로 분석되었다. 또한, 지역의 교육열의 심화에 따른 추가적 교육비 지출은, 기존에도 많이 지출하고 있던 계층에서 더욱 크게 증가고 있음을 알 수 있었다. 지역적 영향력에 관한 이러한 두 가지 결과는, 지역의 경쟁적 환경이 사교육비 지출에 매우 큰 영향을 줄 수 있음을 의미하고 있다.

The advance of the smart working environment came the expectation that it would innovate and revolutionize the way people work, particularly in a society where smart work is readily available for creating a collaborative and 'connected' business. One of the core infrastructure elements for making smart work a viable option is the smart work center, the promotion of which requires a new form of 'smart work center business model' that can satisfy the purposes of both public services and private businesses. This calls for collaboration between the public and private sectors. Recently a number of businesses have been making significant headway in the creation of a new environment for business support and collaboration by adopting a sharing economy business model in their offices. The so-called 'Coworking Space' is an advanced form of business environment in the emerging 'smart work' era, and comes with the benefits of reduced costs as a result of sharing office space and knowledge sharing through the use of human networks. This paper describes the framework of a 'smart work center business model based on the sharing economy' using a BMC (Business Model Canvas), with an understanding of the characteristics inherent to the smart work center and the sharing economy. It was on the basis of this framework that a smart work center model for business incubation and startup, a private smart work center model for childcare services, and a community marketplace model with a global network were developed.

The strength of the PB(Private Brand) is that it can eliminate intermediary in the distribution channel and thoroughly control the quality under its own name. This study has developed traditional studies on private brand proneness in approaching data processing and empirical point of view of a consumer's attitude buildup process on PB through 'recognition-attitude-action(behavioral attitude)'. The subjects of this study are consumers in their $20s{\sim}40s$ who are main customer groups of PBs. A screening process has taken place to select consumers with purchasing experiences of retailor PBs. The data is analyzed by 'Structural Equation Modeling' of Amos 5.0 to verify consumer attitude formation model on private apparel brand. The results generated from this study are as follows: First, the proposed consumer attitude model on private apparel brand consists of store evaluation, experiential product evaluation, cognitive product evaluation, hedonic attitude, utilitarian attitude and purchase intention. Second, not only positively influence on utilitarian attitude but hedonic attitude can arouse positive emotional reaction of a consumer. Third, the store evaluation is ahead of the product evaluation because PB is more related to the image of a store. The influence of the store on PB is relatively stronger when compared with NB.

The current higher education in Vietnam demonstrates the intense competition among local universities. Undoubtedly, the issue of enhancing the brand value to attract students is now placed at the top to Vietnamese universities. The research aims to identify the objective and subjective factors affecting the brand value of private universities in Ho Chi Minh City, Vietnam as mediated by students' perceptions. This paper employs the mixed research methods and data were then analyzed by measuring Cronbach's Alpha coefficient for reliability, analyzing EFA, and using PATH model to test the experiment on the research model affecting HUTECH's brand value. Probability sampling used is Stratified sampling and 500 students of 8 faculties of HUTECH surveyed by convenience sampling. Additionally, this paper also proposes some managerial implications on enhancing the brand value of private universities in Ho Chi Minh City. The results indicate that the new factor, namely geographic location is the most influential factor to enhance the brand value of private universities in general and HUTECH in particular. Brand still plays a determinant role in students' trust when choosing a university. Finally, some implications proposed to enhance the brand value of private universities in Ho Chi Minh City in the context of fierce competition in attracting students.

Private set intersection cardinality (PSI-CA) is a typical problem in the field of secure multi-party computation, which enables two parties calculate the cardinality of intersection securely without revealing any information about their sets. And it is suitable for private data protection scenarios where only the cardinality of the set intersection needs to be calculated. However, most of the currently available PSI-CA protocols only meet the security under the semi-honest model and can't resist the malicious behaviors of participants. To solve the problems above, by the application of the variant of Elgamal cryptography and Bloom filter, we propose an efficient PSI-CA protocol with high security. We also present two new operations on Bloom filter called IBF and BIBF, which could further enhance the safety of private data. Using zero-knowledge proof to ensure the safety under malicious adversary model. Moreover, in order to minimize the error in the results caused by the false positive problem, we use Garbled Bloom Filter and key-value pair packing creatively and present an improved PSI-CA protocol. Through experimental comparison with several existing representative protocols, our protocol runs with linear time complexity and more excellent characters, which is more suitable for practical application scenarios.

This study examined the effect of private educational expenditure on adolescent depression and somatic symptoms. The sample comprised 2,589 first-grade middle-school students who completed the 2018 Korea Children and Youth Panel Survey. Data were analyzed using ANOVA (the generalized linear model), multiple regression, and quantile regression analysis. The principal results were as follows. First, 15.15% of adolescents reported depression symptoms, and 15.57% reported somatic symptoms. Second, levels of depression were significantly different among classes with a different level of private educational expenditure. Third, depression level was significantly negatively associated with private educational expenditure, in that the higher the private educational expenditure, the lower the depression level. Fourth, the effect of private educational expenditure on adolescent depression was significant at the 70~90th quantile regression, suggesting that private educational expenditure was associated with a higher level of depression symptoms. The results indicate that private education was viewed as a consumption commodity rather than a complementary educational practice or investment in human capital. Private education as a commodity might induce the highly developed and costly private education market. In turn, there is an increased financial burden for education at one end of the social-economic continuum and depression caused by relative deprivation at the other end.

Korean households' expenditures on foodservices are on the steady increase. This paper aims to examine the foodservice expenditures of salary and wage earners's households by income decile group. This is analysed through comparing foodservice expenditures with private education expenditures because households' expenditures are likely to be weighted in favor of eating-out rather than private education. We also model the consumption function in terms of income and price, examining the responsiveness of private education demand and eating-out demand to changes in income and price using econometric methods such as regression, rolling regression and impulse response. This paper show that foodservice demand increases more than the private education does in the long-run. The result indicates that households are likely to evaluate the desire for foodservice more important than private education contrary to our expectations in the long-run. The impulse response analysis, however, suggests that households tend to increase private education expenditures rather than eating-out expenditures in the short-run.
