Dental hygienists are important members of any dental clinic. They are recognized as reflecting the dental clinic's image because they spend a lot of time with patients. The longer the dental hygienist is employed, the better the relationship with the patients and the medical service provided. The purpose of the present study was to develop a scale to measure factors of long-term employment among dental hygienists. The basic questions were constructed by analyzing tools used to measure job embeddedness and satisfaction. Forty-one questions were developed that measured organizational fit (13), interpersonal relationships (8), job satisfaction (7), duty satisfaction (6), recognition (4), and self-esteem (3). A questionnaire survey was conducted, and the responses from 297 dental hygienists in dental clinics, after the exclusion of 20 incomplete surveys, were used for the exploratory and confirmatory factor analyses. As revealed by exploratory factor analysis, long-term employment intention was composed of 7 factors consisting of 29 items after the exclusion of 12. The subsequent confirmatory factor analysis revealed 4 factors ("organizational fit," "professional identity," "job connectivity," and "interpersonal relationship") consisting of 16 items, after the exclusion of 13. $Cronbach^{\prime}s\;{\alpha}$ were 0806, 0.836, 0.700, and 0.684 for the four factors. This study is meaningful in that it developed a long-term employment factor measurement tool that can be applied to domestic dental hygienists. Future studies will need to focus more on professional identity and job outcomes. The results of this study and future related ones could be used to improve dental hygienist's continuous service.

Prior research on the fishery village tourism has mainly focused on the development and activities in the field, but lacking in strategic approaches. To overcome such a limitation, this study intends to measure visitors' authenticity on Gijang Anchovy Festival, test reliability and validity of the measurement items, and to identify the relationships among variables by a regression analysis of visitors' satisfaction. Authenticity means the value of existence. The types of tourism in fishing villages have been classified as fishery tourism, resource tourism and ecotourism and each of them has its own authenticity. Based on previous research, this study classified it into three factors such as objective authenticity, experiential authenticity and inauthenticity. To analyze the current situation of Daebyeon Anchovy Festival, measurement scales were developed and survey was conducted on the visitors for the three days from April 20 to 23, 2007. A total of 211 questionnaires were distributed and 208 were collected, The questionnaire contains 25 items on authenticity and 4 items on satisfaction and all the items were measured on the 7 Likert scale. It also has 8 items on demographic characteristics. On the test of reliability and validity of the authenticity, 24 items were used, Cronbach's was 0.7 and correlation was higher than 0.3. Factors of objective authenticity, experiential authenticity and inauthenticity were drawn from the factor analysis, which means that the 24 items may be used to measure authenticity of fishery festivals. The findings show that the evaluation score was 4.89 for objective authenticity, 4.36 for experiential authenticity, and 4.24 for inauthenticity. On the test of the hypotheses, the path coefficients were estimated 0.087 for objective authenticity, 0.202 for experiential authenticity and 0.503 for inauthenticity on the visitors' satisfaction. This suggests some meaningful marketing strategies for Gijang Anchovy Festival. First of all, the anchovy festival should focus on motivating visitors to revisit the festival by identifying individual traits, making a pleasant festival oriented toward family visitors, and providing more experience programs about anchovy.

In this paper, we primarily focus on the perspectives about creative process, which is how mathematical creativity emerged, as one aspect of mathematical creativity and then present a desirable task characteristic to measure and program characteristics to develop mathematical creativity. At first, we describe domain-generality perspective and domain-specificity perspective on creativity. The former regard divergent thinking skill as a key cognitive process embedded in creativity of various discipline domain involving language, science, mathematics, art and so on. In contrast the researchers supporting later perspective insist that the mechanism of creativity is different in each discipline. We understand that the issue on this two perspective effect on task and program to foster and measure creativity in mathematics education beyond theoretical discussion. And then, based on previous theoretical review, we draw a desirable characteristic on instruction program and task to facilitate and test mathematical creativity, and present an applicable task and instruction cases based on Geneplor model at the mathematics class in elementary school. In conclusion, divergent thinking is necessary but sufficient to develop mathematical creativity and need to consider various mathematical reasoning such as generalization, ion and mathematical knowledge.

Information system (IS) security continues to present a challenge for firms. Especially, IT security accident is recently taking place successively in the financial sector. Thus, a comprehensive measure on this is demanded. A large part of a research on security relies upon technical design in nature and is restrictive in a consideration of person and organizational issue. To achieve a goal of firm security, it is possible with an effort of organizational management and supervision for maintaining the technical and procedural status. Based on a theory of accountability, we propose that the security countermeasures of organization lead to an increase in accountability and reduction in risk of IT security in a financial firm and further to firm performance like promotion in firm reliability. In addition, we investigate which difference a theoretical model shows by comparison between South Korean and American financial firms. As a result of analysis, it found that South Korea and America have significant difference, but that a measure on the financing IT security is important for both countries. We aim to enhance interpretability of a research on security by comparatively analysis between countries and conducting a study focus on specific firm called financial business. Our study suggest new theoretical framework to a research of security and provide guideline on design of security to financial firm.

Objectives: This study was designed to confirm the effects of the Korean Medicine health promotion program targeting young children. One important aspect of the Korean Medicine health promotion program for children is to bring awareness of health benefits of introducing Korean Medicine methods to young children and to promote incorporating such methods in children's daily activities to develop healthy habits. Methods: The following experiment was conducted for 6 weeks, and the participants were in the age between 2 to 6 years old from 6 child care centers in Wonju and Chungju. 268 participants were in the intervention group, and 277 in the control group. To measure the outcomes of the Children Korean Medicine health program, the intervention group received Korean Medicine prevention programs (children education, parent education, growth exercises, common cold prevention scarf, and pear herb tea), control group did not. This research collected and compared the following data as the children's health indicators to measure the outcomes before and after the program: medical services usage, the number of absences, early leaves, and tardiness to the child care centers due to the participant's health condition. Results: After applying the children's health promotion programs on children between the age of 2-6, there was a decrease in the overall medical services usage, absences, early leaves, and tardiness to the child care center. This health promotion program was purely based on Korean medical theories and Korean Medicine resources without any conventional medical mediation. Conclusions: It can be concluded that a positive change was noted in raising awareness of Korean Medicine through educating both the parents and children. By learning to incorporate Korean Medicine prevention practices to daily habits, not only was there a reduction in the Medical services usage, but the children also became familiar and comfortable with Korean Medicine and its treatment procedures; the overall satisfaction level of the program was also high.

This study provides a framework to assess network design under the regime of QoE (Quality of Experience). Our approach is expected to reveal the necessity of developing the QoE measures and applying this notion to network design, particularly in the mobile environment. Furthermore, our model shows the ample potential that both users and network providers are able to attain a win-win case by shifting the focus on network design and service operations from QoS (Quality of Service) to QoE. Since the former considers only relevant technological specifications, it may fail in capturing critical factors surrounding users, such as a context where the corresponding user is working on. For example, according to one study [13], the bit-rate, a widely employed QoS measure, shows inferior performance in provisioning network resources to the MOS (Mean Opinion Score), a representative QoE measure. Our framework develops the idea and construct a prototype to systematically assess network design and operations in terms of QoE. The proposed prototype aims at achieving a higher level of efficiency without severely deteriorating users' satisfaction level. We also provide some simulation results which support our idea. That is, reducing the chance of over-provisioning on the basis of the QoE paradigm results in a great flexibility. It may give price cut for users or postponement of network investment for providers or both. Our simulation results also seem robust irrespective of the forms of the QoS-QoE relationship.

In this work, we study the problem of privacy-preservation data publishing in moving objects databases. In particular, the trajectory of a mobile user in a plane is no longer a polyline in a two-dimensional space, instead it is a two-dimensional surface of fixed width $2A_{min}$, where $A_{min}$ defines the semi-diameter of the minimum spatial circular extent that must replace the real location of the mobile user on the XY-plane, in the anonymized (kNN) request. The desired anonymity is not achieved and the entire system becomes vulnerable to attackers, since a malicious attacker can observe that during the time, many of the neighbors' ids change, except for a small number of users. Thus, we reinforce the privacy model by clustering the mobile users according to their motion patterns in (u, ${\theta}$) plane, where u and ${\theta}$ define the velocity measure and the motion direction (angle) respectively. In this case, the anonymized (kNN) request looks up neighbors, who belong to the same cluster with the mobile requester in (u, ${\theta}$) space: Thus, we know that the trajectory of the k-anonymous mobile user is within this surface, but we do not know exactly where. We transform the surface's boundary poly-lines to dual points and we focus on the information distortion introduced by this space translation. We develop a set of efficient spatiotemporal access methods and we experimentally measure the impact of information distortion by comparing the performance results of the same spatiotemporal range queries executed on the original database and on the anonymized one.

As entry barriers at the legal service market in Korea have been recently lifted, the legal service market has dramatically changed from a seller's market to a buyer's market. Externally, the Korean legal service market has been open to foreign law firms and internally, lawyers graduating from law schools have been increasing. In addition, as even the general public can easily access, through the official sites of government organizations, to the basic legal information such as laws and judicial precedents, the degree of information asymmetry has also decreased. These phenomena require the legal service industry to be a more client-oriented and more quality-oriented one. Having said that, legal service providers also need to continue to make strenuous efforts to measure and improve the service quality from the customers' perspective. Under these circumstances, this study introduced a certain type of model which may be of help of measuring and improving the quality of legal service of law firms, in particular, with a focus on those firms providing corporate legal service. This study used a Quality Function Deployment (QFD) in order to measure and thereby improve the quality of corporate legal service in the law firm industry. Above all, this study showed, by using SERVQUAL, each and every service attributes of quality measurement of the corporate legal service and also calculated the degree of importance of service quality at each process of providing corporate legal service. Next, this study introduced all supporting factors necessary for the provision of corporate legal service and calculated the degree of importance of each and every supporting factors in the service process. This study may be of help to provide the substantial and systematic approaches to the corporate legal service providers who would like to set up a certain methods of measuring and further improving the quality of corporate legal service from the customers' perspective.

The noncontact optical sensor using the hologram laser and automatic power controller is developed to measure a thickness of transparent objects and achieve excellent performance. Due to the contact between the tip of the sensor and the surface of objects, the tip is abraded. In addition the casting glass under high temperature results in extending the size of sensor body. The accuracy of the sensor is degraded due to these reasons. In this paper, to overcome these problems, we proposed a low cost non-contact optical sensor that is composed of a hologram laser unit used for optical pickup of CD player and a plastic lens. Therefore the problems caused by the contact sensor are solved by using the noncontact sensor. The noncontact sensor has to move toward the objects and obtain the focus error signal to measure a position of transparent objects. While the internal temperature of the sensor is controlled under ${\pm}0.1^{\circ}$, many trials shows ${\pm}2{\mu}m$ measurement error as excellent performance.

To survive in the trend of the fourth industrial revolution, companies are putting a lot of attention and effort into personalization services using the latest technologies such as big data, artificial intelligence and the Internet of Things, while entrusting third parties to handle personal information on the grounds of work efficiency, expertise and cost reduction. In such an environment, consignors need to check trustees on a more effective and reasonable basis to ensure personal information safety for trustees. This study used AHP techniques to derive the importance and priority of each item of "Personal Information Safety Assurance Measures" for financial companies and trustees, and objectively compared and analyzed differences in perceptions of importance between financial institutions and trustees. Based on this, the company recognizes the difference between self-inspection of financial institutions and inspection of trustees and presents policy grounds and implications for applying differentiated inspection standards that reflect the weights appropriate for the purpose.
