The main purpose of the article is to study the peculiarities of the work of the Ukrainian language in the upper grades of the lyceum based on the activity approach. Despite the fact that a number of scientific studies and applied developments on teaching Ukrainian as a foreign language have recently appeared in Ukrainian linguistics, significant problems in this area should be recognized (organization of the educational process when learning a language as a foreign language, general methodological principles, psycho- and sociolinguistic foundations, communicative approaches), the non-resolution of which leads to methodologically unreasonable teaching of the Ukrainian language as a foreign language, the use of methods of teaching the language as a native language or the study of the language as a subject (linguistic aspect). In addition, due attention is not paid to the development of communication skills, which, firstly, worsens the quality of teaching and learning. Based on the results of the analysis, the key aspects of the work on the Ukrainian language in the senior classes of the lyceum were analyzed on the basis of an activity approach.

It is common in practice to use mean squared error(MSE) for prediction. Recently, Park and Shin (2005) and Jones et al. (2007) studied prediction based on mean squared relative error(MSRE). We proposed a new nonparametric way of prediction based on MSRE substituting Jones et al. (2007) and provided a small simulation study which highly supports the proposed method.

The need for network protection, accounting and resource management in foreign administrative domain requires appropriate security services. In this paper, we propose an access control protocol to support the authentication between mobile node and visiting subnet. Our hybrid way of approach aims to reduce computational overhead and minimize the use of network bandwidth. We also propose non-certificate based public-key cryptography to provide non-repudiation, which does not require CRL retrieval and certificate validation.

Purpose: This study aims to investigate effectiveness in foreign Health Promoting School through a systematic review. Methods: To perform a systematic literature survey, the researcher searched two database (PubMed and Springer Link) for literature relevant to 'health promoting schools' (published up to April 2013 from 2004). The key words used for the search were "effectiveness", "evaluation" and "health promoting school". five evaluations in this review were selected in the peer reviewed. Results: 1. The areas of standardized assessments were dealing with school health policy, physical environment, psycho social environment, community participation, Literacy on health, personal hygienic skills, academic achievement, self reported health status, and mental health. 2. There was evidence that the health promoting school has some positive influence on various domains of assessment. Conclusion: This systematic review provides evidence concerning the effectiveness of the health promoting school.

Corporate Social Responsibility(CSR) is considered recently a key factor for the firm's success and sustainable growth in today's changing business environments. Discussions on CSR are extensively unfolding in various sectors, public, civil society and business organizations, across the world. Consumer in foreign markets have been insisted that multinational corporations and foreign supplier need to adapt their business activities to not only the economic, but also social needs of the consumer. Therefore Korean companies operating in global markets need their global CSR strategy, which will contribute to the improvement of their international competitiveness and long term growth. Thus, the purpose of this study is to report on the strategy of corporate social responsibility through the literature review and illustration of CSR activities of the leading companies in global market. In addition, this paper is aimed to provide Korean firms the insight in reinforcement of global competitiveness in relation of strategic CSR.

This paper adopts the big data research method, and draws 491 data from the Tianya Forum about the Simultaneous Renting and Purchasing policy of Guangzhou. The qualitative analysis software Nvivo11 is used to cluster the main questions about the Simultaneous Renting and Purchasing policy in the forum. The 36 high-frequency word frequencies are obtained through text clustering. Through rooted theory analysis, the main driving factors for summarizing people's doubts are 9 main categories, 3 core categories, and the model of driving factors for online forums is established. The study finds that resource factors are the most key factor, economic factors are the important drivers, and policy guiding factors are sub-important drivers.

Continually having growed up overseas construction market for new Nuclear Power Plant(NPP), the exports of Korean Reactor emerges as the key task of National Nuclear Business. The objective of this study is to strengthen the competitiveness of Korean Reactor through the improvement of Construction Project Contract & Delivery System for NPP. This study suggests the method for increasing Korean Reactor's competitiveness of exports by analyzing the business environment of foreign market and comparing Contract & Delivery System between domestic and foreign.

Generally speaking, power transformations such as Box-Cox transformation(1964) is applied for variance stabilization and symmetry. But, when the distribution of the original data has a large mean with a small variance or the coefficient of variation is very small, they don't work at all. This paper propose a simple method to introduce a shift parameter before applying power transformations and showed the numerical evidence by Monte Carlo simulation and a real data analysis.

Model-based methods are generally used for small area estimation. Recently Shin and Lee (2003) suggested a method which used spatial correlations between areas for data set including some auxiliary variables. However in case of absence of auxiliary variables, Direct estimator is used. Even though direct estimator is unbiased, the large variance of the estimator restricts the use for small area estimation. In this paper, we suggest new estimators which take into account spatial correlation when auxiliary variables are not available. We compared Direct estimator and the newly suggested estimators using MSE, MAE and MB.
