Proof of Work (PoW) based blockchains have limitations in throughput, time consumption, and energy efficiency. In these systems, a miner will consume significant time and resources to obtain a reward for contributing to the blockchain. To overcome these limitations, recent research on blockchains are focused on accelerating the speed, scalability, and enhancing the security level. By enhancing specific procedures of blockchain system, the level of data integrity supported by the blockchain can become more robust, and efficient. In this paper, a new blockchain consensus model based on the Bryllite Consensus Protocol (BCP) is proposed to support a hyper-connected massively multiplayer online game (MMOG) ecosystem. The BCP scheme enables users to participate directly in new consensus processes through a Proof of Participation (PoP) algorithm. In this model, the consensus algorithm has a simpler form while maintaining high security level. In addition, because the BCP scheme gives users an equal chance to make a contribution to the blockchain, rewards are distributed in an equal fashion, which motivates user participation. The analysis of the proposed scheme is applied to the Bryllite consortium blockchain system (homed in Hong Kong), which is a new blockchain network developed for international game industries, gamers, and game events.

Objectives : The purpose of this study was to investigate the effect of participation in social activities on the subjective health satisfaction of the elderly in groups with and without chronic diseases. Methods : Data were used from the "2014 the Korean Elderly Survey" and the subjects were 10,451 persons aged 65 years or older. Data analysis was conducted using SPSS 18.0 statistical package. Results : The results of this study were as follows. In the case of the elderly without chronic diseases, only the employment status (${\beta}=.135$, p<.01) had a significant effect on the health of the elderly. In the case of elderly people with chronic illness, participation in lifelong education (${\beta}=.183$, p<.001), participation in social group (${\beta}=.277$, p<.001), volunteer work experience (${\beta}=.060$, p<.05), and employment status (${\beta}=.342$, p<.001) had a significant effect on health. Conclusions : Policies and systems are needed to actively encourage and support the social activities of the elderly. Additionly, care and attention are needed to provide social jobs for the elderly and build a sustainable network.

Background: A number of accidents have occurred in small and medium enterprises (SMEs). Efforts in reducing accidents have been undertaken through the implementation of safety behaviors. Unfortunately, few studies have examined motives behind unsafe behaviors, such as safety silence motives. This study aimed to observe the motives underlying safety behaviors, namely safety silence motive (SSM) (SSM-relation, SSM-climate, SSM-issue, and SSM-job) and to evaluate the effect of SSM and safety communication on safety participation in different industrial sectors and scales. Materials and Methods: Eighty workers from two industrial sectors and scales of SMEs were involved. They were instructed to fill out a set of questionnaires. A five-Likert scale was used to respond. An independent t test was applied to find any significant differences. The partial least square-structural equation modeling for multigroup was used to develop a model on relations among the variables. Results: The results showed that SSM scores were high in SMEs, and the scores were different across industrial sectors and scales. SSM had a negative influence on safety communication, and safety communication positively influenced safety participation. Conclusion: The study of SSM, safety communication, and safety participation in different sectors and scales should be separated in SMEs.

Anonymity is one of the key factors that influence communication and the work behaviours of people. It is even more evident in an online community where the role of anonymity can be akin to a double-edged sword: it can increase participation while at the same time having detrimental effects due to irresponsible and disruptive behaviour. Most studies on anonymous participation in groups or communities have reported this ambivalent view of anonymity: positive or negative. Furthermore, the effects of anonymous participation may be different in a dynamic sense because the task characteristics of participation can vary across time. In this study, we hypothesise that the effects of anonymity in online collaboration differ across the stages of collaboration. We analysed 2,978 featured articles on the English-language Wikipedia website and investigated the contributions of anonymous participants. While the contributions of anonymous participants were negative to collaboration efficiency as a whole, the negative effect of anonymous participants was stronger in the earlier stage than the later stage of collaboration. These findings indicate that the effect of anonymity has two sides in terms of collaboration efficiency in the same collaborative environment.

This study aimed to analyze the attitudes which married women, who are employed or not, have to the four flexible work conditions; flexible working hours, home-based work, guarantee of reentering into the work place, and a certain allocation of women's labor force. Whether the married women were employed or not, they showed a favorable attitude to the four flexible work conditions. For the married women who were not employed, their age, education level, husband's occupation, their wanted income(if they have a job), and work experience were significant variables to affect the attitudes to each work condition. In contrast to above results, the attitudes to each work condition that the employed women had were significantly different according to more various variables including personal variables, child related variables, and work related variables. suggest that married women hoped the sex conscious systems would be introduced in the labor market.

The purpose of this study was to explore factors influencing on work values of female college students focusing on parental effect to enhance their participation in labor market. The respondents were asked to answer a questionnaire, and the collected 400 data were analyzed using SPSS 23.0. The results showed that the students and their parents had more leisure-oriented and extrinsic work values than labor-oriented and intrinsic work values. The labor-oriented and intrinsic work values appeared to be high in the group with experience of part time jobs, with high educated father or with middle household income. The influencing factors on college students' work values were parental work values, gender consciousness, self-efficacy and major. The results from this study suggest that parents of college students should be educated to change their work values.

A demand for user's participation in the designing process, which is called the participation design, is increasing with social change. Practically, however, there is lack of researches on the improvement of the problem in actual design development and participation design effect. In order to understand the field-based participation design effect in view of user's change of awareness on participation design, this study carried out a survey on the change of awareness through a design workshop in which all stakeholders have participated on the subject of agricultural direct sales facilities as a part of participation design programs. Many references were reviewed first to understand the participation design principles and their current research trend. Next, the questionnaire was developed using an effectiveness verification model for an effective analysis. A design workshop as one of the participation design programs was organized and applied for the field response. In order to analyze the effect, the survey on participants' change of awareness was carried out before and after the program. The survey questionnaires were about motivation, knowledge, recognition, function, and participation and asked the design study graduates. The participation design effect was supplemented by additional open questions. As a consequence, the participants in the participation design program showed the noticeable effect in knowledge and function about the agricultural direct sales facilities. It was found that they were also highly satisfied with the participation design result and they recognized an importance of collaboration. This study also showed that a sufficient time schedule considering agricultural village life should be given for a smooth operation of the program and also a working environment is necessary for designing work.

This study explores the factors influencing employees' use of family-friendly programs. Although recent years have witnessed an increasing number of family-friendly programs offered in the workplace, many studies have reported a lack of their actual use. This study considers various socio-demographic and workplace characteristics such as attitudes toward gender roles, and the perceptions of the work environment to better understand the reason behind this insufficient use. For this, data from the 2nd National Korean Family Survey in 2010 were employed. The results based on a total of 408 employees with diverse occupations indicate that among the four family-friendly programs evaluated(flexible working hours, child care, dependant care, and employee wellbeing), child care programs were most frequently provided by employers. In addition, the factors influencing employee participation in family-friendly programs were associated mainly with workplace characteristics or attitudes toward gender roles. The work environment including the employee's perceptions of how comfortable it is to accept assistance from family-friendly programs was also a key factor. Personal characteristics such as age and attitudes toward gender roles except for family needs had significant effects on employee participation in family-friendly programs. Future research should examine the effects of various environmental factors on employees' responses to family-friendly programs and investigate additional factors that can further enhance the effectiveness of such programs.
