As social interest in emotional labor grows, there are many related studies in progress in recent times. However most of the studies are focused on preventing harmful effects of emotional labor or seeking effective follow-up measures from the service provider's point of view. For this reason, with focusing on the bank teller service which is one of most representative face-to-face emotional labor, this study was progressed to suggest improvement measures by identifying and analyzing the current status of visual installations at the work space for awareness improvement of emotional labor from the customer's point of view. To this end, after a prior study, an field survey of 10 banks in the first financial sector was conducted to draw out problems and finally propose improvement directions with four aspects in link with the problems presented. This study is expected to have meaning in terms of securing diversity in emotional labor related research.

The citation information of academic resources contains the knowledge flow from previous research, so it is possible to connect fragmented research in relational aspects. The citation information can grasp the overall flow of research, so it can promote convergence research such as developing existing research or deriving related fields. Therefore, in this study, the citation information of academic literature, which was previously provided at the level of simple disclosure, was reconstructed based on the citation relationship. Through this, backward and forward citation analysis were conducted based on time series, and the research flow was analyzed by setting the citation stage. Finally, we developed an academic information service that visualizes the main research contents of backward and forward citation based on time series. This accesses academic resources through the meaning contained in the citation information.

This study aims to analyze the visual modeling process of pre-service elementary teachers on the reflection of light. The analytical framework was developed from three aspects; coherence, correspondence, and commensurability of the modeling thinking proposed by Halloun (2004). 20 pre-service elementary teachers participated and were randomly paired to observe the reflection of light. They were asked to construct the visual model individually at first and then collaboratively. Comparing personal and cooperative models, the level of correspondence and commensurability in some groups has increased, despite the lack of special educational treatment. In addition, three main features were found in their reasoning process. First, the level of commensurability to apply the law of reflection continued to change fluidly depending on the circumstances and often the verbal and visual explanations did not match. Second, in the process of visual modeling, correspondence was often given priority over commensurability and coherence. Third, in a situation where correspondence and commensurability are at odds with each other, participants resolved this conflict and developed reasoning through review and revision of the auxiliary hypothesis. Several implications have been discussed for effectively guiding visual modeling activities.

Quality of Service (QoS) is a critical feature of Wireless Sensor Networks (WSNs) with routing algorithms. Data packets are moved between cluster heads with QoS using a number of energy-efficient routing techniques. However, sustaining high scalability while increasing the life of a WSN's networks scenario remains a challenging task. Thus, this research aims to develop an energy-balancing component that ensures equal energy consumption for all network sensors while offering flexible routing without congestion, even at peak hours. This research work proposes a Gravitational Blackhole Search Optimised splay tree routing framework. Based on the splay tree topology, the routing procedure is carried out by the suggested method using three distinct steps. Initially, the proposed GBSO decides the optimal route at initiation phases by choosing the root node with optimum energy in the splay tree. In the selection stage, the steps for energy update and trust update are completed by evaluating a novel reliance function utilising the Parent Reliance (PR) and Grand Parent Reliance (GPR). Finally, in the routing phase, using the fitness measure and the minimal distance, the GBSO algorithm determines the best route for data broadcast. The model results demonstrated the efficacy of the suggested technique with 99.52% packet delivery ratio, a minimum delay of 0.19 s, and a network lifetime of 1750 rounds with 200 nodes. Also, the comparative analysis ensured that the suggested algorithm surpasses the effectiveness of the existing algorithm in all aspects and guaranteed end-to-end delivery of packets.

The world has rapidly become culturally diverse, and Korea has gradually grown into a multicultural society, mainly due to marriage immigrants and foreign laborers, whose number exceeds over one million nationally. Their adjustment and acculturation in Korea, however, dose'nt seem painless and untroubled, and public libraries are in duty to provide multicultural service for these population. Providing useful services on the homepage makes it possible for users to find the information they need without having to visit the actual library. A more detailed research will be conducted by examining the multicultural services provided by the public libraries in Australia, Canada, the United States, and Japan, the leading multicultural societies. The further examination will be conducted on these libraries in terms of four aspects, that is, information, literacy, education, and culture, as declared by Public Library Menifesto. In Korea, translation and interpretation services, homework help, child literacy are necessary services at the public library, Management of independent multicultural site, shared services between Regional Central Library and Community Public Library, cooperation with libraries, government and organization will be helpful to multicultural library services.

Teachers' ability to notice is a crucial indicator of their instructional expertise. Despite the significance of this ability, research in mathematics teacher education has predominantly focused on the noticing of preservice teachers, with limited exploration into the noticing abilities of experienced in-service teachers. This study addresses this gap by examining the noticing characteristics of in-service elementary teachers actively developing their competency in elementary mathematics education. For this purpose, 23 elementary school teachers were asked to complete an analysis sheet while viewing the mathematics lesson video depicting on the concept of (fraction)÷(natural number), allowing us to scrutinize their attending, interpreting, and responding skills in detail. The study's results revealed that teachers demonstrated a tendency to attend mathematically significant aspects related to the teaching of fraction division. They interpreted the observed phenomena through the lens of fraction division's instructional principles, proposing specific pedagogical alternatives. These findings offer valuable insights for mathematics teacher education research.

This study aims to determine the factors affecting the level of satisfaction with the Cell Broadcast Service (CBS) among citizens in Incheon. Partial least squares (PLS) regression, instead of multiple regression, was used for the analysis because it can solve multicollinearity and sample size issues. The analysis results are as follows: The factor with the greatest effect on satisfaction with CBS among Incheon citizens, was the elimination of redundancies (VIP=1.185). Therefore, local governments, government agencies, and public organizations must coordinate their ideas and collectively create guidelines to eliminate redundancies. The second most influential factor was the expansion in the broadcast medium from legal, institutional, and policy aspects (VIP=1.087). This is because differences in generation, age, gender, and personal characteristics were not considered. Therefore, it is necessary to devise a customized messaging tool through the expansion of broadcast media. The broadcast criteria of the legal, institutional, and policy perspectives comprised the third most influential factor, with a high VIP value of 1.053. Consequently, it is essential to devise a plan to avoid distributing unnecessary cell broadcast services, by establishing criteria for areas and sections, time, and the direct and indirect impact zones of a disaster. In the future, this study could be used as base data to develop policies, guidelines, and response measures for Incheon CBS. Given the lack of research on the diverse characteristics of each social class and the city traits of each region, and a lack of concrete empirical research on each factor, continuous and in-depth studies are required in the future.

This thesis examines the problems faced in the electronic trade platform for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's u-TradeHub system are as follows. First, from the technical and legal aspects, to make up for a lack of support systems for spread of users, it is required to promote customized advertising strategies through Ministry of Knowledge Economy and establish a global certification system. Second, document standardization and digitalization should be achieved in advance to make the documents distributed through the e-Trade platform in a seamless manner. Furthermore, an ongoing global network development project should be promoted through the e-Trade platform to achieve standardization. Third, from the operational aspect, it is important to maintain an integrated and systematic relationship with related organizations. Because vertical integration among logistics service providers and GSCM are enabled through the e-Trade platform, it is necessary to standardize global network-based linkage and operating systems.

The psychiatric patients as subjects were categorized herein into disease- and accident-triggered groups to statistically compare them with each other in terms of various comparative items. At a result, male patients were more dominant than females and physical workers were outnumbered by mental workers in the two groups. Also, patients were more apparent at workplaces with at least 100 employees than the ones with less than 100 employees, and patients whose employment period is at least one year were more vulnerable to stress-related mental disorders than the ones whose employment period falls short of one year. The foregoing findings suggest that there is a need to take preventive measures considering vulnerable aspects in terms of mental disorders.

Recently, social network services (SNSs) most notably in Facebook, Twitter, Linkedin have became a worldwide sensation more than the other internet services. This study suggested social conformity theory is appropriate tools for diagnosis to rapid adoption and diffusion of SNSs. Based on previous research, we suggested three different aspects of social conformity:social imitation conformity, social connection conformity, and social comparative conformity. Namely conformity has positive effect on user's three kinds of commitment which called continuance, normative, and affective commitment. we investigated user's commitment to the SNSs have positive effects on user's stickiness intention. Finally, we presented useful implications related to academy and industry.
