Objectives : The purpose of this study was to verify the impact of the empowerment of dental personnels as one of variables affecting the performance of dental institutions and to seek ways of boosting their organizational productivity. Methods : The subjects in this study were dental personnels who worked in dental institutions. After three investigators were trained, a pilot survey was conducted from October 20 to November 20, 2009, and the questionnaire used in the pilot survey was finalized. The collected data were analyzed with a SPSS(Statistical Package for the Social Science) WIN 12.0 program. The findings of the study were as follows: Results: 1. The dental personnels investigated got 3.98 in meaningfulness, one of the empowerment factors. They found a meaning in their job when they performed it. 2. The dental personnels who were older were more excellent in self- determination and influence, and age made a significant difference to their empowerment. 3. The dental personnels who were better educated were more superior in terms of empowerment, and academic credential made a significant difference to their empowerment factors was statistically. 4. The dental personnels whose yearly salary was larger were more which were the factors of empowerment of each factor was statistically significant. 5. Dental health agency workers less than three years accounted for most of 152 people were working longer duration of empowerment as a whole was that each of the factor scores. Empowerment of each factor was statistically significant. 6. The dental hygienists made up the largest group among the dental institution employees, and the kind of occupation made a significant difference to meaningfulness, competency and influence, which were the factors of empowerment. 7. The greatest group of the dental personnels worked in dental clinics, and the dental hospital employees surpassed the dental clinic employees in competency, self-determination and influence. There was a significant difference in the influence factor according to the type of dental institutions. Conclusions : Thus, the dental personnels were more aware of the meaningfulness factor when their perception of the job-related empowerment was checked, and it indicated that most of them attached importance to meaningfulness during their job performance. But just employees who worked in dental institutions located in particular regions were examined, the findings might not be generalizable. In the future, more extensive research should be implemented, and the sorts of programs that could stir up empowerment among dental institution employees or bolster organizational empowerment should be developed.

Recently, the emphasis on self-directed learning and lifelong education is increasing the importance of school libraries in the curriculum. Accordingly, various studies have been conducted mainly from a structural, institutional and operational point of view. However, more research is necessary on the micro topics such as school library users' autonomous intrinsic motivations in the sense that school libraries play key roles in autonomy-based self-directed education. This study aims at finding out what types of school library use motivations are more important and the degree to which the use motivations affect the school library service quality based on the self-determination theory. In addition, this study examines how the use motivations and the perceived service quality vary depending on the school grade of the library users. Based on a focus-group-interview pilot study, a questionnaire survey was administered on the effects of school library motivations on perceived library service quality to 588 students from 5 high schools and 2 middle schools in Seoul. When the service quality and its components, service affect, information control, and library as place were set as dependent variables, in all these four cases, intrinsic motivations were more significant than extrinsic motivations. In addition, when middle school students and high school students were selected as separate analysis target groups, the results of both analyses show that the higher the intrinsic motivations were, the higher the perceived service quality was. The contribution of this study is that it applies the self-determination theory to school library service, measures the influence of motivation type based on the theoretical basis, and focuses on micro aspects to improve school library services.

The purpose of this study was to examine the effect of donation expenditure details and the shift in awareness as a result of disclosure of donation expenditure details in order to promote constant donation by nonprofit organizations in the course of marketing activities. The first experiment was configured through $2{\times}2$ intergroup element design based on 2(feedback on donation expenditure details: available vs. unavailable) ${\times}$ 2(donation awareness: expenditure vs. exchange), and furthermore, MANOVA was performed. The results showed that the satisfaction with donation was higher when the donation expenditure details were disclosed(M=5.125, SD=0.437) and that the relation maintenance intention was higher(p<0.01) when the donation expenditure details were disclosed M=5.328, SD=0.459). In addition, the main effect was validated by using the bootstrapping method. The results of overall model validation showed that satisfaction & trust(=0.843, p<0.01) and satisfaction(=0.267, p<0.01) and trust(=0.691, p<0.01) had a positive(+) relationship. Based on aforesaid results, donors are expected to have greater trust if nonprofit organizations make effort to ensure transparent and detailed disclosure of information on expenditure of donations made by donors. Succeeding studies would need to investigate the effect that might vary depending on the type of feedback methods, etc.

This paper introduces a robot knowledge framework which is represented with multiple classes, levels and layers to implement robot intelligence at real environment for mobile robot. Our root knowledge framework consists of four classes of knowledge (KClass), axioms, rules, a hierarchy of three knowledge levels (KLevel) and three ontology layers (OLayer). Four KClasses including perception, model, activity and context class. One type of rules are used in a way of unidirectional reasoning. And, the other types of rules are used in a way of bi-directional reasoning. The robot knowledge framework enable a robot to integrate robot knowledge from levels of its own sensor data and primitive behaviors to levels of symbolic data and contextual information regardless of class of knowledge. With the integrated knowledge, a robot can have any queries not only through unidirectional reasoning between two adjacent layers but also through bidirectional reasoning among several layers even with uncertain and partial information. To verify our robot knowledge framework, several experiments are successfully performed for object recognition and navigation.

The purpose of this study was to analyze the effect of infographic instruction to promote the use of the scientific model in the 'lens' unit of elementary science textbooks. The participants were $6^{th}$ grade students(n=53) of G elementary school in G city, Gyeongsangnam-do. For this study, the lesson plan of the 'lens' unit consisted of three steps as investigation of students' prior concept about the lens, scientific model construction activity, and infographic construction activity. We then analyzed the results of this study from three perspectives: the scientific concept, scientific model, and infographic. Before the lesson, students focused on the external shape and material of the lens in prior concept of it. However, after the scientific model construction activity and infographic construction activity, students' scientific concept about the lens improved in the categories of features of lens, features of glasses, light path, and applications of the lens. In terms of the scientific model, use of type and frequency of scientific model increased more in the infographic construction activity than the scientific construction model activity. Also, in terms of infographic, the two infographic types as function based infographic and connection based infographic used more than non-infographic in the infographic construction activity. Also, the frequency of Gestal theory's visual perception increased more in the infographic construction activity than the scientific model construction activity.

Oral health is a critical factor for diagnosing overall health, as poor oral health has a negative impact on food intake and results in deterioration of nutritional status. The purpose of this study was to research the needs for food developments for the elderly based on their oral and overall health status. Oral status was significantly associated with self-reported health status, and dry mouth (lack of saliva) especially showed a significant relationship with negative self-perception of both oral and overall health. For both elderly men and women, fish and leafy vegetables were the most preferred side dishes. Bread, rice cake, and beverage-type foods were also preferred for snack development. Disease status of the elderly was significantly related with their preference for food development. For instance, those with diabetes were more likely to ask for anti-diabetic diets. The most important factor for the elderly in choosing food was nutritional balance, and less than 3,000 won was cited as an affordable price. The results could be utilized as basic data to develop foods for the elderly.

Purpose: Patients who suffer from rheumatic arthritis, fibromyalgia, other various inflammatory diseases and musculoskeletal disorders, which are all similar to temporomandibular disorders (TMD), have been complaining about changes in the level and type of pain in response to changes in weather conditions for a long time. Through an investigation about pain perception in TMD patients in response to weather conditions, our primary objective was to develop base materials for future studies on change in pain in response to meteorological factors. Methods: Among patients who presented with TMD to Department of Oral Medicine, Pusan National University Dental Hospital from August to October 2016, one hundred consecutive TMD patients diagnosed with TMDs according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were recruited for the study and 28 patients were excluded according to exclusion criteria. Survey was done with the questionnaire and investigated whether there was any difference in incidence and level of pain in TMD patients between non-rainy and rainy days. Results: Among a total of 72 samples, 4 patients reported change in pain on rainy days rather than non-rainy days. Two patients from chronic group (joint and complex subgroup) reported increased pain on rainy days rather than non-rainy days but it was not statistically significant (p>0.05). One patient from chronic/muscle group reported the change in pain characteristics while pain intensity remained unchanged. One patient from acute/complex group reported decreased pain intensity. In comparison of the patients who reported increased pain on rainy days between acute and chronic groups, there were two reported cases and were both from chronic group only. There was a significantly higher chance of reporting increased pain on rainy days in chronic group than acute group (p<0.001). Conclusions: It is considered that TMD patients couldn't perceive the change in pain well in response to weather change on rainy days but some chronic patients could perceive the increase in pain in rainy days.
