Water Treatment Operation System is applied in most water treatment plants with DCS(Distributed Control System) or PLC(Programmable Logic Controller) system. But it has a lot of problems in viewpoint of cost and expansibilities. Therefore, we rose demand about a system that it was easier, convenient and a few costs. So, It was appeared at a Fieldbus as an alternative about this. It is used in ail industrial fields, but because of the economic reality that we can't removes the existing system, and cannot introduce new technology. Because it is actual to be hard to find an actual implementation reward and way of domestic fieldbus technology, we cannot be acknowledged with reliability in the industrial spot. Therefore, We is going to look into a fieldbus application reward in this paper. That is, We recognize structure and a kind of a fieldbus in a Chapter 2. And we is going to look into difference between a PLC method and fieldbus methods in a Chapter 3. Also, We are going to compare the system that used PLC with the system that used fieldbus (LonWorks). And the objects are JinAn and Wonju where a field bus was applied to.

The purpose of this research is to investigate the level of knowledge management in Korea small firms. The research scheme was experimented through a questionnaire survey answered by 150 firms. The research model was composed of five groups : 1) knowledge management and business strategic, 2) a culture and structure for knowledge management, 3) learning process and community 4) information technology to support knowledge management 5) a reward and performance measurement. The results of this research indicated that the level of knowledge management is different according to the characteristic of small firms. The result of the empirical analysis can be summarized as follows : First, the business culture for knowledge management is not performed pertinently. Second, the learning process for knowledge management and a reward and performance measurement is insufficient. Third, the characteristics of a firm should be considered for measuring the level of knowledge management.

In this paper, we present a new hierarchical model for performance analysis of channel allocation and packet service protocol in wireless n network. The proposed hierarchical model consists of two parts : upper and lower layer models. The upper layer model is the structure state model representing the state of the channel allocation and call service. The lower layer model, which captures the performance of the system within a given structure state, is the wireless packet retransmission protocol model. These models are developed using SRN which is an modeling tool. SRN, an extension of stochastic Petri net, provides compact modeling facilities for system analysis. To get the performance index, appropriate reward rates are assigned to its SRN. Fixed point iteration is used to determine the model parameters that are not available directly as input. That is, the call service time of the upper model can be obtained by packet delay in the lower model, and the packet generation rates of the lower model come from call generation rates of the upper model.

This study aims to explore the characteristics of the working conditions in Korean game industry, focusing on the precarity of game workers. As a research methodology, qualitative and quantitative methods were combined. Specifically, in addition to in-depth interviews with game workers, we conducted a quantitative analysis on adequacy of reward and career prospects recognized by game workers through the Korean Working Conditions Survey(2014/2017). The major findings are as follows. First, game workers were experiencing labor precarity in a way of job insecurity, economic instability and excessive exploitation, as well as loss of autonomy and labor alienation. Second, between 2014 and 2017, the adequacy of reward recognized by game workers was positively improved for companies with 30 or more employees, but was worsen for those with less than 30 employees. In addition, in terms of career prospects, there were no significant changes in the workers of companies with 30 or more employees, but the were worsened for companies with less than 30 employees. These results show that labor precarity in the game industry appears to be different depending on various factors, such as business size, occupation, and career. It also implies that the polarized and inequal structure of the Korean game industry is gradually deepening.

The aim of this study was to find out the possibilities of humanistic education through text analysis of the picture books of Korean fairy tales dealing with poverty and to discuss the educational implications. For this, the two researchers drew the literal roles of poverty and property in the common narrative structure of seven subject books and discussed the humanistic educational implications. The results are as follows. Firstly, the poverty of a main character was related to good personalities rather than negative personalities such as indolent disposition and formed affirmative values. Secondly, divine existence or animal helpers offered property to the good man in a unrealistic manner so that it emphasized the meaning of reward on their good nature. Thirdly, the bad character of wicked men following the good men was focussed on and their greed for property was the evidence of their wickedness. Most of them were punished because of the wicked motive so that it apparently highlighted the lesson of the good triumphing over the evil by the binary opposition structure. Fourthly, all the fairy tales made the characters treated based on the each personality: punishment or reward. However, the reward was usually property so that the property itself was depicted as a kind of blessings. Based on those findings, some humanistic educational implications were discussed.

The study aims to conduct organizational diagnosis at Infosys and to suggest measures of improvement of the same wherever necessary. Data was collected with the help of a structured questionnaire. Respondents were selected with the help of random sampling technique. The sample size is 19. The employees are not much clear about their goals and the purpose of the organization. The employees are not satisfied with the current structure and the division of the work in the organization, and also with the current reward mechanism of the organization. However the employees are satisfied with their leaders and their leadership styles. The employees feel that they share a good relationship with their peers. The employees of Infosys have full confidence in the management and they believe that the management is helping them in their career growth. Some of the interventions suggested are as follows: Role Analysis Technique can be used so that the employees get clarity of their goals. As the score suggests that the employees are not happy with the current structure and distribution of the work, mentors can be assigned to the employees who can guide them and can also help the employees to understand the structure and processes better.

User created content (UCC) is created and shared by common users on line. From the user's perspective, the increase of UCCs has led to an expansion of alternative means of communications, while from the business perspective UCCs have formed an environment in which an abundant amount of new contents can be produced. Despite outward quantitative growth, however, many aspects of UCCs do not meet the expectations of general users in terms of quality, and this can be observed through pirated contents and user-copied contents. The purpose of this research is to investigate effective methods for fostering production of creative user-generated content. This study proposes two core elements, namely, reward and motivation, which are believed to enhance content creativity as well as the mediating factor and users' committement, which will be effective for bridging the increasing motivation and content creativity. Based on this perspective, this research takes an in-depth look at issues related to constructing the dimensions of reward and motivation in UCC services for creative content product, which are identified in three phases. First, three dimensions of rewards have been proposed: task dimension, social dimension, and organizational dimention. The task dimension rewards are related to the inherent characteristics of a task such as writing blog articles and pasting photos. Four concrete ways of providing task-related rewards in UCC environments are suggested in this study, which include skill variety, task significance, task identity, and autonomy. The social dimensioni rewards are related to the connected relationships among users. The organizational dimension consists of monetary payoff and recognition from others. Second, the two types of motivations are suggested to be affected by the diverse rewards schemes: intrinsic motivation and extrinsic motivation. Intrinsic motivation occurs when people create new UCC contents for its' own sake, whereas extrinsic motivation occurs when people create new contents for other purposes such as fame and money. Third, commitments are suggested to work as important mediating variables between motivation and content creativity. We believe commitments are especially important in online environments because they have been found to exert stronger impacts on the Internet users than other relevant factors do. Two types of commitments are suggested in this study: emotional commitment and continuity commitment. Finally, content creativity is proposed as the final dependent variable in this study. We provide a systematic method to measure the creativity of UCC content based on the prior studies in creativity measurement. The method includes expert evaluation of blog pages posted by the Internet users. In order to test the theoretical model of our study, 133 active blog users were recruited to participate in a group discussion as well as a survey. They were asked to fill out a questionnaire on their commitment, motivation and rewards of creating UCC contents. At the same time, their creativity was measured by independent experts using Torrance Tests of Creative Thinking. Finally, two independent users visited the study participants' blog pages and evaluated their content creativity using the Creative Products Semantic Scale. All the data were compiled and analyzed through structural equation modeling. We first conducted a confirmatory factor analysis to validate the measurement model of our research. It was found that measures used in our study satisfied the requirement of reliability, convergent validity as well as discriminant validity. Given the fact that our measurement model is valid and reliable, we proceeded to conduct a structural model analysis. The results indicated that all the variables in our model had higher than necessary explanatory powers in terms of R-square values. The study results identified several important reward shemes. First of all, skill variety, task importance, task identity, and automony were all found to have significant influences on the intrinsic motivation of creating UCC contents. Also, the relationship with other users was found to have strong influences upon both intrinsic and extrinsic motivation. Finally, the opportunity to get recognition for their UCC work was found to have a significant impact on the extrinsic motivation of UCC users. However, different from our expectation, monetary compensation was found not to have a significant impact on the extrinsic motivation. It was also found that commitment was an important mediating factor in UCC environment between motivation and content creativity. A more fully mediating model was found to have the highest explanation power compared to no-mediation or partially mediated models. This paper ends with implications of the study results. First, from the theoretical perspective this study proposes and empirically validates the commitment as an important mediating factor between motivation and content creativity. This result reflects the characteristics of online environment in which the UCC creation activities occur voluntarily. Second, from the practical perspective this study proposes several concrete reward factors that are germane to the UCC environment, and their effectiveness to the content creativity is estimated. In addition to the quantitive results of relative importance of the reward factrs, this study also proposes concrete ways to provide the rewards in the UCC environment based on the FGI data that are collected after our participants finish asnwering survey questions. Finally, from the methodological perspective, this study suggests and implements a way to measure the UCC content creativity independently from the content generators' creativity, which can be used later by future research on UCC creativity. In sum, this study proposes and validates important reward features and their relations to the motivation, commitment, and the content creativity in UCC environment, which is believed to be one of the most important factors for the success of UCC and Web 2.0. As such, this study can provide significant theoretical as well as practical bases for fostering creativity in UCC contents.

Ferroelectric thin films have been widely investigated for future nonvolatile memory application. We fabricated the BLT ($(Bi,La)_4Ti_3O_{12}$) films on Si using a STA ($SrTa_2O_6$) buffer layer BLT and STA film were prepared by sol-gel method. Measurement data by XRD and AFM, showed that BLT film and STA films were well crystallized and a good surface morphology. From C-V measurement reward that the Au/BLT/STA/Si structure showed a clockwise hysteresis loop with a memory window of 1.5 V for the bias voltage sweep of ${\pm}5$ V. From results, the Au/BLT/STA/Si structure is useful for FeFETs.

Purpose: This study presents a translation, cultural adaptation, and psychometric evaluation of two instruments of the Fertility Awareness and Attitudes Towards Parenthood (FAAP) questionnaire (Conditions and Life changes) for use in South Korea. Methods: This methodological study included 166 university students for psychometric evaluation in the sixth step. The first five steps included forward translation, backward translation, committee review, assessment of content validity, and a pre-test. In the sixth step, psychometric properties, including internal consistency, construct validity, and criterion validity, were evaluated. Exploratory factor analysis and confirmatory factor analysis were conducted to identify the structure of the tool and to assess its validity. Results: The Korean version showed acceptable internal consistency. Cronbach's α was .73 for FAAP-Conditions and .83 for FAAP-Life changes. FAAP-Conditions showed a four-factor structure (social conditions, relationship with partner, external environment, and child-rearing support) and FAAP-Life changes had a two-factor structure (reward and burden). In the confirmatory analysis, CMIN/DF, TLI, IFI, SRMR, CFI, and RMSEA were satisfactory. Conclusion: This study provided preliminary evidence of the acceptability, reliability, and validity of the Korean version of the FAAP questionnaire in university students in South Korea. Nonetheless, further evaluation among Korean young adults is warranted to validate this instrument.
