The foodservice industry should be customer-oriented and service-oriented because production and consumption occur simultaneously and sales depend on customers' participation in the foodservice industry. In this respect, it is faced with maintaining minimum human resources with efficient management systems and policies which employees can offer quality services. This study, therefore, aims to find out how internal marketing strategies affect conflict perception. The result of the study is as follows. Communication, service training, employee benefits and a reward system are generally important in the internal marketing. In particular, it is considered that employee benefits and a reward system based on finance are more important to employees than any other factor. Accordingly, companies should consider facilities offered to the employees, vacation and employee benefits. Also, it is shown that communication-obstacles take high proportion in the cause of conflicts and employee benefits in the internal marketing. This study showed the possibility of internal marketing used as a management method of human resources and a solution for resolving conflicts.

Background: In this study we investigated factors influencing cancer screening intention and behavior to develop measures to increase the rate of cancer screening in the Korean elderly. Materials and Methods: Participants included 425 elderly subjects 65 years of age or older from D city, South Korea. The health behavior characteristics and cancer screening-related and theory of planned behavior (TPB) factors influencing the participant attitudes on cancer screening were examined to identify determinants significantly affecting cancer screening intentions and behavior. Results: Predictive factors influencing cancer screening behavior included smoking, exercise, cancer concerns, preference for the type of cancer screening, prior experience with the National Cancer Screening Program, perception of the National Cancer Screening Program, behavioral control with respect to cancer screening and cancer screening intentions. The factors influencing cancer screening behavior were different from those for cancer screening intentions. Conclusions: Increasing the cancer screening intentions of the elderly is necessary to raise the rates of cancer screening. Additionally, identifying the inhibitory factors that serve as obstacles to cancer screening in the elderly and changing screening intentions into actual screening behavior is necessary. This study provides a reference for developing and applying policy measures and intervention strategies to increase the cancer screening rates of the elderly in Korea.

The researches on driver assistance systems that can prevent an accident have been actively performed due to social issues of traffic accidents with development of vehicle industry in recent. It is required for researchers to develope systems which assist driver's perception and judgment when considering that over 70% of traffic accidents occur by drivers' carelessness and 75% of the total accidents occur at the speed of less 29km per hour. In this paper, we implemented a front and rear vehicle monitoring system that monitors distance from a vehicle to obstacles in real-time at the low-speed or back-ward driving. The proposed system consists of ultrasonic sensors of high angle and wide angle of beam spread, ATmega128, and DSP processor.

This paper investigates minimum safe distances relative to a ship's four cardinal sides, as perceived by Filipino navigators when encountering dangerous elements and in adverse weather conditions when maneuvering in and around harbors. It uses a descriptive research method in the form of a questionnaire survey for experienced Filipino navigators of various ranks. During the course of research, 71 responses were colleted and the resulting data is presented in graphical and tabulated forms. Statistical methods including Pearson-product moment correlations, Cronbach's Alpha and ANOVA were used to identify internal associations, consistencies and significances, respectively. It has been proven that there are no significant differences in minimum safe distances relative to a ship's four cardinal sides, whether maneuvering while approaching a port or within an inner harbor. This study has been deemed significant for training future navigators, managing traffic in fairways, and designing harbors and maneuvering areas in the approaches to ports, among other applications. This work can also be used as a preliminary study for comparison with the well known safe domains presently in use.

This paper presents a robust autonomous navigation and reconnaissance system for tracked robots, designed to handle complex multi-floor indoor environments with stairs. We introduce a localization algorithm that adjusts scan matching parameters to robustly estimate positions and create maps in environments with scarce features, such as narrow rooms and staircases. Our system also features a path planning algorithm that calculates distance costs from surrounding obstacles, integrated with a specialized PID controller tuned to the robot's differential kinematics for collision-free navigation in confined spaces. The perception module leverages multi-image fusion and camera-LiDAR fusion to accurately detect and map the 3D positions of objects around the robot in real time. Through practical tests in real settings, we have verified that our system performs reliably. Based on this reliability, we expect that our research team's autonomous reconnaissance system will be practically utilized in actual disaster situations and environments that are difficult for humans to access, thereby making a significant contribution.

The purpose of this study was to analyze the perception factors of a pedestrian environment that affect pedestrian environment satisfaction(PES) and determine the relationship between PES and the expected effects of health promotion. The targeted areas of study are neighborhood parks in Suseong-gu, Daegu city. First, regarding the results for the evaluation of pedestrian environment perception, 'Gentle slope' was rated the highest, while factors regarding pedestrian safety such as 'Lots of unpleasant elements', 'Risk from biking and motorcycling' and 'Many obstacles on sidewalks' were rated low. A stepwise regression analysis showed that factors such as 'Fresh air', 'Beautiful scenery', 'Continuity of the sidewalks', 'Various attractions', 'The shade of trees' and 'Lots of unpleasant elements' influenced the PES. Therefore, creating fresh air and shade trees by planting trees and removing unpleasant elements from pedestrian areas are important. Also, it is necessary to cultivate beautiful scenery and attractions through street improvement and improve the continuity of the sidewalks. Finally, in terms of path analysis, PES influenced the frequency of park use, the expected effects of physical and mental health promotion both directly and indirectly.

The Purpose of this study is the applicaion of social network analysis for expanding the use of spatial data in local government. Spatial data generated from UIS projects play very important roles as a means of supporting decision making and solving complicated urban problems, but the utilization of the spatial data has not reach the expected level, considering to the huge amount of investment. Accordingly, there should be efforts in efficient management of spatial data, establishment of a sharing system, and expanded utilization of spatial data. Social network analysis applied to this research is a theory that explains the behaviors and patterns of units forming the system and measures distances between nodes, strength, etc. based on relations among nodes forming the network and the structural characteristics of the network. According to the results of surveying civil servants who were using spatial data on Busan Metropolitan City, obstacles to the sharing of spatial data were mostly non technical factors related to data users' attitude and their relations with circumstances. In order to expand the use of spatial data, this study performed social network analysis that applied the theory of planned behavior and examined the flow of spatial data, and by doing so, we analyzed related personnel's perception, identified obstacles to data sharing, and suggested a framework for promoting the expanded utilization of spatial data.

The purpose of this study is to analyze related studies and domestic/international online reference cases, extract obstructive factors present in online reference services, and reveal whether or not there are differences in perception between the university librarian and the users. The results with respect to the failure of the resources revealed that while the user considers the quantitative / qualitative shortage of content as the greatest obstacle in the online reference service, librarians see the lack of human resources (Specialist Librarian / trained staff) in this light. Users think this is the least of the problems. In addition, other obstacles that are the most highly evaluated by librarians are, in order, the limitation of service because of copyright issues, the difficulty of information retrieval and complexity of methods of use, and a general lack of information in the reference services menu and missing information in the main menu. For the users the other most important obstacles were similar with the limitation of service because of copyright issues being highest, followed by the difficulty of access because of the confusion over service names, and the general lack of information in the reference services menu and missing information in the main menu.

In this paper, we propose the optimal migration path searching method including path adjustment and reassignment techniques for an efficient migration of mobile agent which has an autonomous ability for some task processing. In traditional agent system, if the various and large quantify of task processing were required from the users, it could be derive excessive network traffic and overload due to increasing the size of agent. And also, if an agent migrates from node to node according to routing schedules specified by the user at which the most of network traffic occurs, it could not actively cope with particular situations such as communication loss and node obstacles and required much cost for node traversal Therefore. this paper presents the migration method of agent which can try to adjust and reassign path to the destination automatically through the optimal path search using by network traffic perception in stead of the passive routing schedule by the user. An optimal migration path searching and adjustment methods ensure the migration reliability on distributed nodes and reduce the traversal task processing time of mobile agent by avoiding network traffic paths and node obstacles.

In this study, we explored the meaning of astronomical observation activities of five earth science teachers through in-depth interviews. Semi-structured interviews were conducted after providing a questionnaire based on Seidman's three-step process of interview. By analyzing the interview transcript, the educational implications inherent in astronomical observation activities were extracted. Teachers have constructed systematic basis of observation and astronomy in the observational astronomy and laboratory class during their course in the teacher education institute. After they became in-service teachers, practical know-hows of astronomical observation activities in schools were developed with the help of colleagues. By designing and executing astronomical observation activities for students, teachers notice positive changes in the cognitive domain, affective domain, and career perception of the students. Hence, teachers consider that astronomical observation activities have great educational effects. In addition, astronomical activities appear to be very rewarding and satisfying experiences to teachers, by providing opportunities for having pride as an earth science teacher. However, teachers tend to find difficulties in operating astronomical observation activities in fields, due to both internal and external obstacles. It is found that the removal of internal obstacles is more important for teachers to attempt or to continue astronomical observation activities. In this sense, it is necessary to support teachers by providing timely training courses with related content, as well as opportunities to share their experiences within a peer group such as teachers' research society.
