This article aims to examine the status of multicultural families in Korea from 2010 to 2020, while analyzing their problems and reasons from a multi-layered perspective, to provide an academic foundation for reference in supporting a social safety system for the stable settlement of those families. Although foreign immigrants experience a certain acceptance due to economic necessity, this attitude is often only a conditional and partial acceptance that does not consider migrants as full members of the community and, moreover, sometimes even suspects them of promoting social division through their presence. This study comprehensively analyzes the current status, problems, and causes of problems in multicultural families in Korea through related data between 2010 and 2020. The problems of multicultural families are manifested mainly in economic, cultural and social terms, and each of these problems is organically interconnected. International marriages between Korean men and female immigrants from developing countries are facing a special set of issues such as unequal status of the spouses or specific problems in child’s education. These problems are serious in the sense that they are not only a temporary burden for the multicultural families, but can also affect future generations, the chances of their development and their inclusion in society. Analysis of these problems, which lie in factors of the social environment and cultural differences, can serve as a basis for countermeasures that will benefit multicultural families in Korea. The problems of multinational families must be understood and addressed in their intertwined complexity in order to find solutions that benefit not only these families, but ultimately society as a whole.
Regularized estimation in GINAR(p) process
Haixiang Zhang,Dehui Wang,Liuquan Sun 한국통계학회 2017 Journal of the Korean Statistical Society Vol.46 No.4
This article is concerned with the regularized estimation methodology for generalized pthorder integer-valued autoregressive (GINAR(p)) process, especially when the regression coefficients are sparse. Under some mild regularity conditions, we show that the regularized estimators perform as well as if the correct submodel was known. The oracle properties of the estimators are established. Extensive Monte Carlo simulation studies demonstrate that the proposed procedure works well. To illustrate its usefulness, an application to a real data about epileptic patient is also provided.
Nonparametric comparison of recurrent event processes based on panel count data
Da Xu,Jianguo Sun,Dehui Wang 한국통계학회 2016 Journal of the Korean Statistical Society Vol.45 No.2
Recurrent event processes arise in many fields including medical follow-up studies and reliability experiments and many procedures have been developed in the literature for their comparison nonparametrically (Cook and Lawless, 2007; Sun and Zhao, 2013). However, most of them are for either the complete data situation where one observes recurrent event data or the incomplete data situation where one observes panel count data with the same observation process. There also exist a couple of nonparametric comparison procedures for the panel count data situation that allow unequal observation processes, but apply only to limited situations. In this paper, we discuss the latter situation for both univariate and multivariate panel count data and propose a new type of nonparametric procedures that apply to more general situations. The proposed test statistics are shown to have asymptotic normal distributions, and an extensive simulation is conducted and suggests that they work well in practical situations. An application is also provided.

This paper is concerned with the design and performance analysis of networked control systems, whererandom network-induced delay, packet disorder, and packet dropout in the feedback and forward channels areconsidered simultaneously and further treated as the round-trip time (RTT) delay. To actively compensate forthe RTT delay, a networked predictive control scheme is designed based on the input-output difference equationmodel. For time-varying reference signals, the resulting closed-loop system can achieve the same output trackingperformance and closed-loop stability as the corresponding local control system. Specifically, for the step referenceinput, it can provide a zero steady-state output tracking error. The controller design problem is solved by usingthe augmented state-space model as well as the static output feedback strategy. In addition, the stability of theclosed-loop system is also discussed for the plant subject to bounded disturbances and modelling errors. Finally,simulation and experimental results are given to demonstrate the effectiveness of the proposed method.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
