In the model tested here, individual innovative work behavior is considered as the outcome of two antecedent factors-empowerment and organizational supports. The relationships between those variables and innovative work behavior are analyzed form the data collected through a questionnaire survey of 389 employees in five general hospitals. Results of multiple regression analyses show that three dimensions of empowerment-meaning, competence, and impact, and supports from organizational culture have significant effects on innovative work behavior whereas the effects of choice dimension of empowerment and managerial supports are not significant. These results emphasize the importance of empowerment and innovation oriented organizational culture for individual members' innovative work behavior. Theoretical and practical Implications and suggestions for future research are discussed.

Recently, most tech-based products are of multiple generations, since new-generation products are replacing the older ones as technologies continue to improve. Although, this means that research is needed to examine as much about the role of post-adoption behavior as the missing link between the adoptions of successive generation as first adoption of innovation, there is a dearth of literature explicitly examining consumers' post-adoption behavior, especially in the context of subscription-based service. For the subscription-based services, in spite of the important role of consumer satisfaction, research on the post-adoption behavior can not carefully examine the direct impact of consumer satisfaction on their decision to upgrade by considering usage instead of satisfaction as the missing link between buyers' first adoption and their next-generation adoption. This study identified two types of attribute satisfaction such as basic attribute and core attribute using both literature review and FGI (Focus Group Interview), and tries to investigate how two types of attribute satisfaction has influence on customers' intention to upgrade to the next-generation services. and a moderating role of customer loyalty between attribute satisfaction and intention. The empirical results show that core-attribute satisfaction has a negative influence on customers' intention to upgrade, due to the moderating role of customer loyalty, but it can raise their intention to upgrade next-generation services. However, basic-attribute satisfaction, on the other hand, appears to positively influence both customer loyalty and the intention to upgrade. We also find that the consumer attribute satisfaction is influenced by consumer innovativeness, her perception of service and the usage of each features' type in different ways. Finally, academic and practical implication is made, limitation is clarified and a direction for further studies is suggested.

This paper investigates the relationship between R&D professionals' career plateau and organizational commitment in which career plateau's sub-dimensions consist of structural and job-content plateau. Further, it aims to examine the moderating effect of age and creative behavior of R&D professionals on the relationship between career plateau and organizational commitment. Empirical data were collected from 418 R&D professionals who work for Government sponsored research institutions. The results showed that the relationship between structural plateau and organizational commitment is differently related depending on age level. That is, the negative relationship between structural plateau and organizational commitment is stronger for junior R&D professionals. Furthermore, the relationship between job-content plateau and organizational commitment is negatively related, and differs in the strength depending on the creative behavior level of R&D professionals. For one with stronger characteristics of creative behavior, job-content plateau is more negatively related to organizational commitment. Based on the results, some implications are suggested on the career plateau issues of R&D professionals who work for government sponsored research institutions. Finally, it is discussed on the limitations of this study and further research directions.

Betta rubra, classified as endangered fish species by the International Union for Conservation of Nature (IUCN), has been successfully bred and raised in captivity for two generations under laboratory conditions. This study aimed to provide comprehensive information on the captive breeding of B. rubra, focusing on various parameters crucial for ex-situ conservation and domestication. The research involved breeding trials, embryo and larvae observation, first feeding experiments, larva and fry rearing trials, and the evaluation of growth and reproduction in two generations. The study revealed that the female B. rubra, with an average total length of 5.17 ± 0.15 cm and weight of 1.61 ± 0.06 g, produced an average of 73.67 ± 7.09 eggs, 34.33 ± 5.13 total larvae, and exhibited a hatching rate of 46.67 ± 5.77%. The embryogenesis process commenced on the day of spawning (dps) and continued until the eggs hatched at 6 dps. Larvae development and yolk absorption occurred from 0 to 6 days post-hatching (dph). The study also examined the impact of different initial feeding options, with chopped Tubifex resulting in the most significant in- crease (p < 0.05) in length. The growth pattern of B. rubra larvae showed slow initial growth during the first seven days, followed by a rapid exponential growth phase from day 8 to day 39. Two generations of B. rubra (G1 and G2) were successfully bred in captivity, with G2 showing a better tendency for growth in length and weight compared to G1. Notably, there were no significant differences (p > 0.05) in reproductive success between the wild-origin broodstock (G0), G1, or G2. This research contributes valuable insights into the captive breeding of B. rubra and its early life stages, offering critical information for the conservation and sustainable management of this endangered species. Further research is needed to explore the long-term effects of domestication on behavior, physiology, and phenotypic diversity.

Diffusion of innovation is the process in which an innovation is communicated through certain channels over time among the members of a social system. The literatures have emphasized the importance of interpersonal network influences on individuals in convincing them to adopt innovations and thereby promoting its diffusion. In particular, the behavior of opinion leaders who lead in influencing others' opinion is important in determining the rate of adoption of innovation in a system. Centrality has been recognized as a good indicator that quantifies a node's influences on others in a given network. However, recent studies have questioned its relevance on various different types of diffusion processes. In this regard, this study aims at examining the effect of a node exhibiting high centrality on expediting diffusion of innovations. In particular, we considered the situation where two innovations compete with each other to be adopted by potential adopters who are personally connected with each other. In order to analyze this competitive diffusion process, we developed a simulation model and conducted regression analyses on the outcomes of the simulations performed. The results suggest that the effect of a node with high centrality can be substantially reduced depending upon the type of a network structure or the adoption thresholds of potential adopters in a network.

To develop creep resistant die-cast Mg alloys, various alloying elements, including Ca, Ce, and Sr, were added to a Mg-Al alloy. The AXE710 alloy was produced on a 320 ton high-pressure die casting machine. The microstructure and creep properties of the alloy were examined. The creep behavior was investigated at $150^{\circ}C$ for stresses ranging from 50 to 100 MPa. The stress exponent was derived from the relationship between normalized secondary creep rates and compensated effective stresses. It was found to be 4.9, indicating that the dislocation climb is a dominant creep mechanism.

For a battery module where single cells are connected in series, the single cells should each have a similar state of charge (SOC) to prevent them from being exposed to an overcharge or over-discharge during charge-discharge cycling. To detect the existence of unbalanced SOC cells in a battery module, we propose a simple measurement method using a single-frequency response of electrochemical impedance spectroscopy (EIS). For a commercially available graphite/nickel-cobalt-aluminum-oxide lithium-ion cell, the cell impedance increases significantly below SOC20%, while the impedance in the medium SOC region (SOC20%-SOC80%) remains low with only minor changes. This impedance behavior is mostly due to the elementary processes of cathode reactions in the cell. Among the impedance values (Z, Z', Z"), the imaginary component of Z" regarding cathode reactions changes heavily as a function of SOC, in particular, when the EIS measurement is performed around 0.1 Hz. Thanks to the significant difference in the time constant of cathode reactions between ≤SOC10% and ≥SOC20%, a single-frequency EIS measurement enlarges the difference in impedance between balanced and unbalanced cells in the module and facilitates an ~80% improvement in the detection signal compared to results with conventional EIS measurements.

Purpose - While studying the topic of seeking behavioral excellence (proactive and creative competence) in organization, scholars have presented a variety of literature sprinkled with countless theories on behavioral competence. Research design, data, and methodology - Foremost among the several theories on this topic are two distinct sets of behavioral theories: OCB (Organizational Citizenship Behavior) and Constructive Deviance. Both of these theories attempt to posit their usefulness in positive organizational outcomes (such as organizational effectiveness, quality, performance, and innovations). Results - However, their proposed constructs are opposing and studies are conducted in isolation, thereby creating a significant literature gap and omitting the possibility of being inclusive of the best that both OCB and constructive deviance have to offer. Conclusions - The article bridges the gap by critically examining OCB and constructive deviance and including a consideration of other empirical studies in an attempt to be comprehensive while, at the same time, seeking to find an effective behavioral construct that is both appropriate and conducive for positive organizational outcomes in the context of the current business environment.
