This paper presents the design of block lengths for irregular low-density parity-check (LDPC) codes based on the maximum variable degree $d_{{\upsilon},max}$. To design a block length, the performance degradation of belief-propagation (BP) decoding performance from upper bounds on the maximum likelihood (ML) decoding performance is used as an important factor. Since for large block lengths, the performance of irregular LDPC codes is very close to the Shannon limit, we focus on moderate block lengths ($5{\times}10^2\;{\leq}\;N\;{\leq}\;4{\times}10^3$). Given degree distributions, the purpose of our paper is to find proper block lengths based on the maximum variable degree $d_{{\upsilon},max}$. We also present some simulation results which show how a block length can be optimized.

In this study, we intended to show the interaction effect between brand reputation and chronic regulatory focus, and intended to show mederatory effect as an interaction as well as the main effect of two variable. To this end, Pulmuone(a high level of brand reputation) and Green(a low level of brand reputation) as parent brand and cosmetics as extention product were selected. The results of the study are as follows: The first, on brand extension evaluation, a high level of brand reputation was more positive than a low level of brand reputation. The second, brand extension evaluation was mere positive in the promotion focus group than in the prevention focus group. The third, In case of high level of brand reputation, there was no significant differences between the prevention focus group and the promotion focus group in brand extension evaluation. On the other hand, low level of brand reputation, there was significant differences between two variables. Therefore, we found the interaction effect between promotion focus group and prevention focus group.

To investigate the interplay between individual and collective self-regulations, the authors propose a dialectic process that describes the changes in the locus of self-regulations between individual self and collective self. The results from three studies display a strong support for the two sets of hypotheses drawn from the proposed process. Our findings demonstrate that consumers can move the locus of self-regulation from individual-self to collective-self when a social identity is activated (preliminary study and study1). Further examination of regulatory swing between individual and collective regulatory orientations revealed group identification as a key variable in determining the locus of self-regulation (study2). While a consumer with a high level of group identification changes her locus of self-regulation from an individual to a collective (a regulatory shift) and evaluated messages and products framed consistent with their group orientation, a consumer with low level of group identification maintains her locus of self-regulation in her personal level of self (a regulatory preservation) and evaluated messages and products framed consistent with their personal regulatory focus.

Purpose - Due to the heavy reliance on the human dependence, several factors such as attitude, behavior, emotional status and the quality of the service by the employees have been a decisive effect on the existence of a business in service industry. This study made use of the cases from the beauty salons in Korea, and tried to find out the meaningful results with following purposes. The purpose of this study is to find out the effects of psychological ownership with focusing on the employees in service industry. Therefore, this study is based on the literature reviews in the fields of psychological ownership, regulatory focus, and customer satisfaction. In particular, this study focuses on the regulatory focus with two parts. The two parts are composed of the promotion focus and prevention focus. Also, the relationship between the regulatory focus on employee and customer satisfaction was identified through empirical study. Mediating effects of regulatory focus were also studied, that is, the regulatory focus was on the relationship between psychological ownership and customer satisfaction. In conclusion, practical and intellectual implications were discussed for the growth and development in service industry. Research design, data & methodology - The survey for this study was conducted from November 15th to December 15th in 2015. The same amount of survey was given to both, the service providers and customers. For both of them, such as the service providers and customers, 260 questionnaires were distributed to them in total. After excluding the missing and unreliable responses for the exact analysis and process, 250 responses were collected and used in the research analysis. This study conducted a survey questionnaires, and the confirmatory analysis was used for the reliability and validity in this study. SPSS & AMOS programs were used for the analysis. Results - The first variable that was looked at from this study is the psychological ownership. The psychological ownership had positive effects on the performance both in improving focus and prevention focus. It indicates that this study supports the results from the previous studies. Second, the effects on the performance in improving focus and prevention focus for customer satisfaction were studied. As a result, the performance in improving focus had positive effect on customer satisfaction, but prevention focus did not have any positive effect. Third, this study looked at the mediating effect of regulatory focus on the relationship between the psychological ownership and the customer satisfaction, and only partly, they had positive effects on customer satisfaction. Conclusions - The results of this study showed that the psychological ownership has positive effects on regulatory focus both in performance improving focus and prevention focus. However, the mediating effects had partial positive effects on customer satisfaction and these results indicate that the service enterprises should focus on the employees' psychological ownership in order to maximize the customers' satisfaction.

The influence of the emotion of envy as a variable in the brand attitude has increased. This study validates the influence of envy types, brand awareness, and regulatory focus chronic of consumers on favorability of luxury fashion brand. This study was designed with the mixed factorial design of 2 (envy types: benign vs malicious) ${\times}$ 2 (brand awareness types: high vs low) ${\times}$ 2 (regulatory focus chronic types: promotion focus vs prevention focus). The data for this research was collected from a questionnaire distributed to 302 subjects aged between 20 and 39 in the Seoul and Gyeonggi areas; consequently, a total of 275 data were analyzed. Data were analyzed with SPSS 23 program and three-way ANOVA, Simple interaction effects and simple main effects analysis were conducted. The results of this research were as follows. First, envy type and brand awareness showed significant interaction for the favorability of a luxury fashion brand. Second, envy type, brand awareness, and consumers' regulatory focus chronic showed significant interaction on the favorability of luxury fashion brand. Based on the findings, the characteristics of consumers' regulatory focus in brand attitude must be taken into consideration by luxury fashion brand marketers. The use of SNS strategies to induce emotions of benign envy through the comparisons to close acquaintances is recommended in order to raise brand preferability.

A novel rte control algorithm consisting of two major components, i.e. a variable encoding frame rate method and a hybrid DCT/wavelet I-frame coding scheme, is proposed in this work for low bit rate video coding. Most existing rate control algorithms for low bit rate video focus on bit allocation at the macroblock level under a constant frame rate assumption. The proposed rate control algorithm is able to adjust the encoding frame rate at the expense of tolerable time-delay. Furthermore, an R-D optimized hybrid DCT/wavelet scheme is used for effective I-frame coding. The new rate-control algorithm attempts to achieve a good balance between spatial quality and temporal quality to enhance the overall human perceptual quality at low bit rates. It is demonstrated that the rate control algorithm achieves higher coding efficiency at low bit rates with a low additional computational cost. The variable frame rate method and hybrid I-frame coding scheme are compatible with the bi stream structure of H.263+.
