The current and ethnic issues represented in child-rearing practices of Korean-Chinese families in YanBian, China, were studied with the participation of 7 primary caregivers (4 mothers and 3 grandmothers) of young children who were interviewed and observed in their homes. Current issues were categorized as competitive bilingual ability, expectations about third language learning (English), expectations of high academic accomplishment and early education, and economic challenges in parenting. Ethnicity issues included ethnic pride as Korean-Chinese, conflicts of ethnic education, participation in local Korean culture, and rearing the child to have the self-expressive and assertive characteristics of typical Korean children. Results were discussed in terms of understanding and supporting child-rearing of minorities and families with multi-cultural background.

This article discusses a capacity planning method in QoS-guaranteed IP networks such as BcN (Broadband convergence Network). Since IP based networks have been developed to transport best-effort data traffic, the introduction of multi-service component in BcN requires fundamental modifications in capacity planning and network dimensioning. In this article, we present the key issues of the capacity planning in multi-service IP networks. To provide a foundation for network dimensioning procedure, we describe a systematic approach for classification and modeling of BcN traffic based on the QoS requirements of BcN services. We propose a capacity planning framework considering data traffic and real-time streaming traffic separately. The multi-service Erlang model, an extension of the conventional Erlang B loss model, is introduced to determine required link capacity for the call based real-time streaming traffic. The application of multi-service Erlang model can provide significant improvement in network planning due to sharing of network bandwidth among the different services.

In this paper, an intelligent method called BELBIC (Brain Emotional Learning Based Intelligent Controller) is used to control of Locally Linear Neuro-Fuzzy Model (LOLIMOT) of Washing Machine. The Locally Linear Neuro-Fuzzy Model of Washing Machine is obtained based on previously extracted data. One of the important issues in using BELBIC is its parameters setting. On the other hand, the controller design for Washing Machine is a multi objective problem. Indeed, the two objectives, energy consumption and effectiveness of washing process, are main issues in this problem, and these two objectives are in contrast. Due to these challenges, a Multi Objective Genetic Algorithm is used for tuning the BELBIC parameters. The algorithm provides a set of non-dominated set points rather than a single point, so the designer has the advantage of selecting the desired set point. With considering the proper parameters after using additional assumptions, the simulation results show that this controller with optimal parameters has very good performance and considerable saving in energy consumption.

The purpose of this study was to offer improvements, by deriving practical problems and suggesting ways to improve more realistic solutions in the multi-family housing management industry. This study is conducted in two ways. First, it was performed by reviewing related previous studies and clarifying major issues in the multi-family housing management. Second, it was performed by a questionnaire survey method, focused on the worker's opinions for that matters. The respondents work in an apartment in Seoul and the metropolitan area. A questionnaire distributed via e-mail, and then were collected. And questionnaire did not respond were excluded from the analysis. Finding were as follows -; first, it was possible to clarify four types regarding major issues in the multi-family housing management such as 'management system', 'housing management market conditions', 'management consciousness of resident', 'management performances'. Second, it was found that the competition was fierce in the same kind. And it was quite a high turnover rate of workers because of poor working conditions. Third, the most hard part was that the employee welfare was not good at work.

Many Applications of scientific research have coupled with functional data signal clustering techniques to discover novel characteristics that can be used for the diagnoses of several issues. In this article we present an interpretable multi-scale cluster hierarchy framework for clustering functional data using its multi-aspect frequency information. The suggested method focuses on how to effectively select transformed features/variables in unsupervised manner so that finally reduce the data dimension and achieve the multi-purposed clustering. Specially, we apply our suggested method to mutual fund returns and make superior-performing funds group based on different aspects such as global patterns, seasonal variations, levels of noise, and their combinations. To promise our method producing a quality cluster hierarchy, we give some empirical results under the simulation study and a set of real life data. This research will contribute to financial market analysis and flexibly fit to other research fields with clustering purposes.

When several parties are involved in a dispute, it is usually considered desirable that the issues should be dealt with in the same proceedings, rather than in a series of separate proceedings. This saves time and money. It avoids the possibility of conflicting decisions on the same issues of law and fact, since all issues are determined by the same tribunal at the same time. Where there is a multi-party arbitration, it may be because there are several parties to one contract, or it may be because there are several contracts with different parties that have a bearing on the matters in dispute. In international trade and commerce, for individuals, corporations or state agencies to join together in a joint venture or consortium or in some other legal relationship of this kind, in order to enter into a contract with another party or parties, where such a contract contains an arbitration clause and a dispute arises, the members of the consortium or joint venture may decided that they would each like to appoint an arbitrator. A different problem arises where there are several contracts with different parties, each of which has a bearing on the issues in dispute. A major international construction project is likely to involve not only the employer and the main contractor, but also a host of special suppliers and sub-contractors. Each of them will be operating under different contracts often with different choice of law and arbitration clauses. The appointment of the arbitrator or the composition of the arbitral tribunal should be in accordance with the agreement of the parties. The parties have to be equally treated in the constituting of the arbitral tribunal and the arbitral proceedings. However, the right of the parties to nominate a member of the arbitral tribunal could be taken away from them, if they are subject to the restrictions by means of the law of the country where the arbitration is taking place. That is, multiple parties jointly should nominate one arbitrator, where there they have to exercise their substantive right in common, or one of them exert his substantive right, then it has an effect on another parties, or they, whether as claimant or as respondent, get the same or similar treatment in the arbitral procedure. Therefore it is necessary to intend to settle multi-party disputes quickly and efficiently.

In multi-interface multi-channel(MIMC) based tactical ad hoc networks, QoS support for required operational capacity is one of the main challenging issues for multi-hop transmissions. To support QoS in such a harsh environment, we propose a novel MAC scheme to minimize multi-hop as well as per-hop delay. The current IEEE 802.11 MAC protocols should contend to reserve the channel resource at every hop by each sender. The every-hop channel contention results in a degradation of end-to-end delay for multi-hop transmissions. The basic idea of our scheme is to make a "multi-hop reservation" at the MAC layer by using the modified RTS frame. It contains additional information such as destination information, packet priority, and hop count, etc. In addition, we differentiate the contention window area according to the packet priority and the number of hops to deliver packets in the predefined allowed latency. Our scheme can minimize the multi-hop delay and support the QoS of the critical data in real time(i.e., VoIP, sensing video data, Video conference between commanders). Our simulation study and numerical analysis show that the proposed scheme outperforms the IEEE 802.11 MAC.

Since the Fukushima Daiichi accident, there has been an emphasis on the risk resulting from multi-unit accidents. Human reliability analysis (HRA) is one of the important issues in multi-unit probabilistic safety assessment (MUPSA). Hence, there is a need to properly identify all the human and organizational factors relevant to a multi-unit incident scenario in a nuclear power plant (NPP). This study identifies and categorizes the human and organizational factors relevant to a multi-unit incident scenario of NPPs based on a review of relevant literature. These factors are then analyzed to ascertain all possible unit-to-unit interactions that need to be considered in the multi-unit HRA and the pattern of interactions. The human and organizational factors are classified into five categories: organization, work device, task, performance shaping factors, and environmental factors. The identification and classification of these factors will significantly contribute to the development of adequate strategies and guidelines for managing multi-unit accidents. This study is a necessary initial step in developing an effective HRA method for multiple NPP units in a site.
