This study explores the factors that moderate the impact of competitive strategy on resource sharing in order to explain why existing empirical research has not shown statistically significant results. We test the hypothesis that competitive strategy pursuing low-cost rather than differentiation increases resource sharing and analyze how the relationship between competitive strategy and resource sharing changes when diversification, interconnectedness, centralization of authority, and resource level are entered into the equation as moderating variables. According to the results, competitive strategy doesn't affect resource sharing alone, but it has significant effects on resource sharing when it is combined with interconnectedness, centralization of authority, and resource level, except for diversification. This means that low-cost strategy increases resource sharing under the conditions of high interconnectedness, more centralized authority, and low resource level. The prior discussions have focused on the willingness or intentions of resource sharing without considering the abilities or possibilities. Our findings indicate that resource sharing could be better predicted by using moderating variables reflecting the abilities or possibilities. The contribution of the study is that we discover and complement the vulnerability in the logic of resource sharing.

The main purpose of the current research was to induce the importance of manners through the relationship between the level of transformational leadership in the family and the degree of job satisfaction in workers. It also examined positive variants that can enhance the degree of job satisfaction. The data from 250 questionnaires were used for the final analysis. The main results of the present study are as follows: First, the level of transformational leadership in the family tended to be relatively low, although it was good at the intellectual stimulus leadership among the sub-dimension of the "Family Multifactor Leadership Questionnaire." Moreover, communication, status, and education level turned out to be most influential background variables. Secondly, the score for job satisfaction that is recognized by the workers appeared to be less than average. It seemed that relative comparison in the level of life, communication and education level were the most influential variables. Indeed, the result of stepwise regression analysis showed that transformational leadership made a comparatively high contribution to job satisfaction. Therefore, it is important to keep in mind that a worker's leadership development is a main source of maintaining job satisfaction.

The purpose of this study is to estimate the extent of fisheries resource rebuilding and other economic effects on coastal gill-net fishery as a result of the Korean vessel buy-back program using with-without analysis based on methods estimating sustainable yields for all species caught by coastal gill-net fishery. Based on the results of with-without analysis, maximum sustainable yields (MSY) of all species caught by coastal gill-net fishery have been increased by the Korean vessel buy-back program. In addition, profits per vessel of maximum economic yield (MEY) of the species have been improved by the program. Further, yields and a producer surplus per vessel under an equilibrium of open access (OA) have increased because of the program. In detail, first of all, at the MSY level, the vessel buy-back program has led to about 21% fisheries resource recovery, and at the MEY level, it has led to about a 19% resource recovery. Secondly, at the MEY level and the OA level, the producer surplus per vessel has been increased by about 24% and 22% respectively by the vessel buy-back program.

This study examines the level of resource-saving behavior among children and attempts to identify the variables-among socio-demographic, socio-environmental, and consumer attitude variables-that are most influential on this behavior. The research was conducted in 2010, following a preliminary study, and the data was garnered from 500 questionnaires that were distributed to elementary students in Seoul. The data were analyzed using a number of statistical methods, including frequencies, percentiles, means, standard deviation, Cronbach's coefficient, ANOVA, and hierarchical multiple linear regression analysis, using SPSS 18.0. The major findings of this study were as follows. First, the average level of resource-saving behavior of children was found to be 3.6 out of 5, indicating relatively rational behavior. Second, the variables that were found to have the greatest influence on children's resource-saving behavior were lower allowance, higher levels of education on the role of consumption, and more active socialization in childhood. Therefore, these variables should be taken into account when teaching children how to establish resource-saving behavior in their daily living.

This article proposed the authentication protocol for peer-to-peer resource sharing community. The proposed protocol does not require a priori information for generating and exchanging authentication key. Also this protocol can provide the delicate access control by allowing the user(authenticator) to assign the trust level to the authentication supplicant, which can be used to decide if the resource providing node will accept the resource sharing request from a resource requesting node. Trust Relationship Chaining provides the environment where trust levels (included in the trust table) of nodes in the resource sharing community are propagated among nodes when trust tables are exchanged between two nodes engaged in mutual authentication process and authentication refresh so that any two nodes which are not directly mutual-authenticated can assign the trust level each other for the access control for resource sharing. In the proposed protocol a node can implements the authentication refresh continuously to verify the effectiveness of authentication after mutual authentication so that the authentication of new node or authentication revocation(effectiveness cancellation) of the departed node can be propagated to the all the nodes in RSC and eventually safe resource sharing community is configured.

This study aimed to investigate resource transfer for baby boomers' adult children and related factors pertaining to baby boomers' later-life preparation. This study was conducted in 2016 using written questionnaires completed by 405 baby boomers residing in Seoul and metropolitan cities in South Korea. The data were analyzed using IBM SPSS Statistics 23.0 and the following statistical methods: frequency, percentiles, the mean, standard deviation, a t-test, one-way ANOVA, Cronbach's alpha, and hierarchical multiple linear regression analysis. Baby boomers' average level of later-life preparation was found to be 3.45/5, a relatively rational score. Baby boomers tended to transfer more resource from their adult children when they had many adult children, were more satisfied with their romantic relationship. Baby boomers' level of later-life preparation was higher when there was lesser resource transfer of their adult children. The greatest influential variables pertaining to the respondents' later-life preparation were their family's income, children's marital status, satisfaction with their romantic relationship, and level of transfer from their adult children. It was concluded that baby boomers have insufficient later-life preparation in terms of finances due to their need to support their adult children; thus, nation-wide practical programs are needed to prepare baby boomers for a happy life.

As mobile computers and embedded systems are becoming popular recently, we need to study how to utilize the resources such as power, space, CPU clocks, and memory efficiently. In traditional embedded system development, we were interested in resource usage based on hardware but, as software is becoming more important, we need to study how to analyze the resource usage based on software. In this research, we propose a new method called 'Instruction Level Resource Usage Analysis Method' and implement it as a resource usage analysis tool called 'I-Debugger'. I-Debugger is constructed on three layers: debugging layer which controls the execution of software on instruction level, statistic layer which gathers real-time data and convert to useful information, and analysis layer which generate useful information to specific applications. We have applied the debugger to some simple problem and found that our method is useful in developing resource efficient embedded systems.

Purpose - The purpose of this study is to explore the determinants of the organizational level for the advancement of smart factory. We suggested three determinants of the organizational level such as CEO's entrepreneurship, high-involvement human resource management, and cooperative industrial relations. Design/methodology/approach - The population of our survey was manufacturing SMEs, and we took a sample and conducted a survey of 232 companies. Since the level of smart factory advancement, which is a dependent variable, was measured on an ordinal scale, ordinal logistic regression analysis was used to test the hypothesis. Findings - The higher the level of high-involvement human resource management, the higher the level of smart factory advancement. As the level of high-involvement human resource management increases by one unit, the probability of smart factory advancement increases by 22.8%. On the other hand, the CEO's entrepreneurship did not significantly affect the level of smart factory advancement. Interestingly, the cooperative industrial relations negatively affected to the level of smart factory advancement, contrary to the hypothesis prediction. Research implications or Originality - This study explored determinants at the organizational level that affect the advancement of smart factories. Through this, various implications are presented for related research and policy fields.

The purpose of this study is to examine the level of conspicuous consumption and resource-saving behavior in primary school students, and to discover the factors that influence these behaviors most strongly. The research was conducted in 2011 using a written questionnaires that were completed by 500 primary school students residing in Seoul, South Korea. The data was analyzed using statistical methods, including frequency, percentiles, means, standard deviation, Cronbach's coefficient, ANOVA, and hierarchical multiple linear regression analysis, using SPSS 18.0. As a result of these analyses, the average level of conspicuous consumption was found to be 2.65 relatively rational score. Next, it was shown that the conspicuous consumption of respondents differed significantly based on variables, such as allowances, family income, socialization process in childhood, family cohesion, and parental child rearing method. Finally, the greatest influences on respondent's resource-saving behavior was seen to be the child's socialization process in childhood, family cohesion, parental child rearing method, and conspicuous consumption. These variables must therefore all be considered when teaching primary school students and encouraging them to assume rational resource-saving habits in their daily lives.

In this paper, we introduce an adaptive radio resource allocation for IP-based mobile satellite services. We also present a synchronous multibeam CDMA satellite system using an orthogonal resource sharing mechanism among downlink beams for the adaptive packet transmission. The simulation results, using a Ka-band mobile satellite channel and various packet scheduling schemes, show that the proposed system and resource allocation scheme improves the beam throughput by more than two times over conventional systems. The simulation results also show that, in multibeam satellite systems, a system-level adaptation to a user's channel and interference conditions according to user locations and current packet traffic is more efficient in terms of throughput improvement than a user-level adaptation.
