Background: The purpose of this study was to examine the differences in the formation of dental hygienist images based on the pathways of obtaining occupational information and to establish a foundation for the correct perception and positive promotion of the dental hygienist profession. Methods: A survey was distributed to 305 college preparatory students in the metropolitan area. The questionnaire consisted of 34 items, including general characteristics(3 items), pathway-related questions(3 items), dental hygienist image-related question(2 1items), application-related questions(2 items), and admission-related questions(5 items). The images of dental hygienists based on general characteristics, perception pathways, and admission were analyzed using the Mann-Whitney U test and Kruskal-Wallis test. Results: The survey results from all participants showed that the overall image of dental hygienists was 3.75 points. Personal image scored the highest at 4.18 points, while social image was the lowest at 3.20 points(p<0.05). The overall image of dental hygienists was higher for the 'online' group (3.88) compared to the 'offline' group, and statistically significant differences were observed among groups in overall, personal, and professional images(p<0.05). The overall image of dental hygienists was higher for those who learned offline (3.87), and the only significant difference between groups was seen in the personal image. When it came to admission, the 'admitted' students gave a higher overall score (4.00) compared to 'non-admitted' students (3.64), with significance found in all areas except for social image (p<0.05). Conclusion: It is believed that effective utilization of online pathways can inform more people about the importance and expertise of dental hygienists, thereby contributing to promoting oral health and enhancing the perception of the profession. Properly valuing and educating about the role of dental hygienists through promotion and education can help improve the image of the profession.

When a vulnerability occurs in a program, it is documented and published through CVE. However, some vulnerabilities do not disclose the details of the vulnerability and in many cases the source code is not published. In the absence of such information, in order to find a vulnerability, you must find the vulnerability at the binary level. This paper aims to find out-of-bounds read vulnerability that occur very frequently among vulnerability. In this paper, we design a memory area using memory access information appearing in binary code. Out-of-bounds Read vulnerability is detected through the designed memory structure. The proposed tool showed better in code coverage and detection efficiency than the existing tools.

Since XML allows users to define any tags, XML documents with various structures have been created. Accordingly, many studies on clustering and searching the XML documents based on the similarity of paths have been done in order to manage the documents efficiently. To retrieve XML documents having similar structures, the three-dimensional bitmap indexing technique uses a path as a unit when it creates an index. If a path structure is changed, the technique recognizes it as a new path. Thus, another technique to measure the similarity of paths was proposed. To compute the similarity between two paths, the technique compares every node of the paths. It causes unnecessary comparison of the nodes, which do not exist in common between the two paths. In this paper, we propose a new technique that minimizes the comparison using signatures and show the performance evaluation results of the technique. The comparison speed of proposed technique was 20 percent faster than the existing technique.

The study developed physical distribution channel choice models reflecting decision making of the firms and studied how choice decision factors influence selection of distribution channel. The distribution channel survey data in Korea was used to do empirical study. As a choice set, distribution channels were classified into two main choice channels: direct and indirect channels. In addition, indirect channels were classified into other three channels according to the type of intermediate point: distribution center, wholesale store, and agency. This study developed choice models by applying both binary and multinomial logit model with various set of factors. The results showed that the developed logit models seemingly reflect distribution channel choice behaviors. The hypothesis tests on how each factor influences choice of distribution channel were performed and discussed as well.

This paper proposes an improved path-planning technique based on the $A^*$ algorithm. The conventional $A^*$ algorithm only considers the optimality of the planned path and sometimes produces a path that an unmanned underwater vehicle (UUV) cannot navigate due to its dynamic constraint such as the limit of the radius of gyration. It is because that the previous method evaluate the moving cost based on the straight distance between nodes. We enhance the conventional method by evaluating the moving cost on the basis of the practically navigable trajectory, which is generated by the waypoint-tracking control of the UUV dynamics. The simulation examples indeed show the effectiveness of the proposed technique.

The purpose of this study was to identify the loneliness and spiritual needs of the elderly in a certain area. The participants in this study were over 65 years, 159 elderly who attended in senior classes in Seoul. The instruments used for this study were revised UCLA 'Loneliness scale' developed by Russell, Peplau & Cutrona (1980) and translated by Kim & Kim (1989) and 'Spiritual need scale' developed by Yong (2008). The collected data were analyzed using SPSS 15.0 program, t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. The score of loneliness was 2.02/4, spiritual need was 4.51/5. The relationship between loneliness and spiritual needs showed significant negative correlation. Loneliness of the elderly who do not attend a religious attendance was high and spiritual needs were low. Spiritual needs of the elderly who are women over 80 years and living with subsidy from the government were high. Spiritual nursing interventions are needed to reduce a feeling of loneliness among the elderly who experience high degree of loneliness.

과거 할인점에서의 상품구색은 대체로 가격이 저렴한 제품들로 구성되어 있었지만, 외국계 할인점이 국내에 진출하고 할인점들 간 경쟁이 치열해지면서 할인점은 매장을 고급스럽게 디자인하고 상품가치가 높고 지명도가 높은 제품들로 구색을 갖추고 있다. 이러한 할인점의 새로운 위상정립에 따라 할인점에서의 화장품 매대도 진열과 구색이 변화되고 있는데, 본 연구는 할인점에서의 화장품 매대 및 취급상표의 특징, 그리고 화장품 매대를 쇼핑하는 소비자의 행태에 관한 자료를 수집 및 분석한 후, 그 결과를 종합하여 메이커와 소비자 측면에서 할인점을 통한 화장품 판매현황을 분석하였다. 조사결과 소비자들은 화장품 구매 장소로서 할인점을 기존 화장품 전문점보다 모든 측면에서 우수한 구매 장소로 인식하고 있었고, 백화점에 비해서도 나쁘지 않은 것으로 평가하고 있었다. 또한 메이커들도 할인점의 화장품매장에 대한 지원을 강화하고 있고, 할인점 전용상표를 개발하여 일반 화장품 전문점 및 백화점과 차별화된 유통경로를 구축하기 위하여 노력하고 있음이 확인되었다.

At present, the number of local governments using the Traffic Information Center are increasing and drivers are utilizing its traffic information from VMS installed on roads in cities. However, the cases of the user's utility of VMS about urban roads with special characteristics different from expressways and urban highways haven't been evaluated so far. Because VMS is a medium installed from a budget to provide traffic information, it is necessary to evaluate and manage the efficiency of users. This study judged that the efficiency of the drivers using VMS of urban roads most influences the duty on alternative route information provision so that it established its evaluation criteria. In addition, it needs to raise its value by many drivers' observation of VMS. Therefore, in case of the same conditions, the installation location of VMS should be a road section with much traffic volume so its the evaluation criteria was established. At present, the study results can be utilized to raise the user's utility of VMS installed in the urban roads.

This study was conducted to examine mediative effects of two factors, emotion control and thinking control, in the relationship between avoid fusion and attention. Participants (308 high school students) were asked to complete a questionnaire which contains items to measure some psychological properties such as emotion control (EC), thinking control (TC), avoidance avoid fusion (CF), conceration(Co) and learning attitude(LA). Structural equation model analysis showed that 8 of modified 9 paths were statistically significant; CF to Co and TC, TC to EC, Co, and LA, EC to Co and LA, and Co to LA. Limitations and suggestions were mentioned in the discussion.
