Purpose: To investigate the efficacy of pregabalin for patients with primary burning mouth syndrome (BMS) who are unresponsive to topical clonazepam therapy. Methods: By searching the clinical electronic records from the Department of Oral Medicine, Pusan National University Dental Hospital from 2012 to 2014, a retrospective analysis was performed on patients with primary BMS who were treated with topical clonazepam therapy during this period. Of the patients who were unresponsive to this therapy, 19 patients who were subsequently treated with pregabalin were included in the study. A pain assessment was performed using the 11-point numerical rating scale at first visit, following topical clonazepam therapy, and again after pregabalin therapy. The treatment outcomes were statistically analyzed using the Wilcoxon signed rank test. Results: Following additional pregabalin administration, the mean pain score was slightly reduced. A total of 7 patients reported a marked response (>50% pain reduction), and 3 patients reported a slight reduction in pain. Pain reduction following pregabalin therapy was statistically significant (p<0.05). Conclusions: Pregabalin has a slight therapeutic effect on patients with primary BMS. Therefore, we recommend pregabalin as an alternative drug for BMS patients who are unresponsive to topical clonazepam therapy.

PURPOSE. This study was to evaluate the effects of bacterial cellulose (BC) membranes as a barrier membrane on guided bone regeneration (GBR) in comparison with those of the resorbable collagen membranes. MATERIALS AND METHODS. BC membranes were fabricated using biomimetic technology. Surface properties were analyzed, Mechanical properties were measured, in vitro cell proliferation test were performed with NIH3T3 cells and in vivo study were performed with rat calvarial defect and histomorphometric analysis was done. The Mann-Whitney U test and the Wilcoxon signed rank test was used (${\alpha}<.05$). RESULTS. BC membrane showed significantly higher mechanical properties such as wet tensile strength than collagen membrane and represented a three-dimensional multilayered structure cross-linked by nano-fibers with 60 % porosity. In vitro study, cell adhesion and proliferation were observed on BC membrane. However, morphology of the cells was found to be less differentiated, and the cell proliferation rate was lower than those of the cells on collagen membrane. In vivo study, the grafted BC membrane did not induce inflammatory response, and maintained adequate space for bone regeneration. An amount of new bone formation in defect region loaded with BC membrane was significantly similar to that of collagen membrane application. CONCLUSION. BC membrane has potential to be used as a barrier membrane, and efficacy of the membrane on GBR is comparable to that of collagen membrane.

PURPOSE. This study examined the effects of the abutment types and dynamic loading on the stability of implant prostheses with three types of implant abutments prepared using different fabrication methods by measuring removal torque both before and after dynamic loading. MATERIALS AND METHODS. Three groups of abutments were produced using different types of fabrication methods; stock abutment, gold cast abutment, and CAD/CAM custom abutment. A customized jig was fabricated to apply the load at $30^{\circ}$ to the long axis. The implant fixtures were fixed to the jig, and connected to the abutments with a 30 Ncm tightening torque. A sine curved dynamic load was applied for $10^5$ cycles between 25 and 250 N at 14 Hz. Removal torque before loading and after loading were evaluated. The SPSS was used for statistical analysis of the results. A Kruskal-Wallis test was performed to compare screw loosening between the abutment systems. A Wilcoxon signed-rank test was performed to compare screw loosening between before and after loading in each group (${\alpha}$=0.05). RESULTS. Removal torque value before loading and after loading was the highest in stock abutment, which was then followed by gold cast abutment and CAD/CAM custom abutment, but there were no significant differences. CONCLUSION. The abutment types did not have a significant influence on short term screw loosening. On the other hand, after $10^5$ cycles dynamic loading, CAD/CAM custom abutment affected the initial screw loosening, but stock abutment and gold cast abutment did not.

Purpose: This study was done to determine whether a parenting education program using responsive teaching strategies is effective for parenting stress, maternal interactional behavior and behavioral problems in children at risk for Attention Deficit Hyperactivity Disorder (ADHD). Methods: Participants in this study were 17 elementary school children and their parents. The ADHD risk group was determined by scores on the Korean-ADHD Rating Scale. The parenting education program was developed based on Dr. Mahoney's responsive teaching curriculum. Mothers participated in the program once a week for 8 sessions. Treatment outcome was evaluated using the Korean version of the Child Behavior CheckList (K-CBCL), parenting stress, maternal interactional behavior, and child pivotal developmental behavior. Data were analyzed using Wilcoxon signed rank test, Mann-Whitney test, and regression analysis. Results: After the parenting education program, no significant difference in parenting stress (Z=-1.00, p=.320) was found, but there was a significant decrease in the child's internal behavior problems (Z=-2.05, p=.040), and also a significant improvement in maternal interactional behavior and a significant difference in child pivotal developmental behavior (Z=-2.67, p=.008). Conclusion: The results indicate that parenting education programs based on responsive teaching strategies are effective and that application of a program is recommended to prevent behavioral problems and improve maternal child interaction for children at risk for ADHD.

In empirical evaluations of public projects and public provided goods, MCDA(multicriteria decision-making analysis) has helped decision makers with an adequate policy decision-making tool since it allows taking into account a wide range of assessment criteria. As a tool for decision-making of conflict management, MCDA has demonstrated its usefulness in many public projects such as road, dam and harbor construction. In this study, to use this merit of MCDA, dam project assessment indicators from points of social, economic, environmental and practical views are developed based on sustainable development of water resources, and weighting factors are also estimated by means of questionnaire survey. In order to decide project investment rank, developed evaluation indicators are applied to 6 existing dams under investigation for a rehabilitation project. In addition to, it is recognized that the project practicability has become more important indicator as well as environmental and social issues. This is because cooperation and support from a local government and people are regarded as one of the most important problems in public projects recently.

This exploratory research explores the concept of a digital legacy as a general concept and as a collection of digital possessions with unique characteristics. The results reported in this article are part of a larger study. In Cushing (2013), the author identified the characteristics of a digital possession. In this study, these characteristics of a digital possession were utilized to explore how the characteristics of several digital possessions could form a collection, or a digital legacy. In addition to being explored as a collection of digital possessions, data was collected about the general concept of a digital legacy. In part I of the study, 23 participants from three age groups were interviewed about their general concept of a digital legacy. Five general characteristics describing a digital legacy were identified. In part II of the study, interview data from Cushing (2013) was used to create statements describing digital possessions. The statements were classified utilizing the archival concept of primary and secondary values, as well as the consumer behavior concepts of self extension to possessions and possession attachment. Primary value refers to the purpose for which the item was created, while secondary value refers to an additional value that the participants can perceive the item to hold, such as a perception that an item can represent one's identity. Using standard Q method procedure, 48 participants were directed to rank their agreement with 60 statements (written on cards), along a distribution of -5 to +5, according to the characteristics of the digital possession they would most like to maintain for a digital legacy. The ranked statements were analyzed using Q factor analysis, in order to perceive the most common statements associated with maintaining digital possessions for a digital legacy. Q method results suggested that most individuals described the digital possessions they wanted to maintain for a digital legacy using various combinations of characteristics associated with primary and secondary values. This suggests that while some participants will respond to personal archiving based on the concept of preserving identity (a perceived secondary value), this will not appeal to everyone. Information professional could consider this difference in appeal when marketing personal archiving assistance to patrons.

This study investigated consumer perception and purchase behavior regarding Han-gwa (traditional Korean confection) in housewives residing in the Seoul and Gyeonggi area. This study was conducted by self-administered questionnaires. Out of 839 questionnaires, 713 questionnaires (85.0%) were used for statistical analyses including frequency analysis, the Chisquare, and one-way ANOVA. Based on the data collected, independence variables were divided less than 40 years (<40), 40s, 50 years or higher (50) by age. The major findings were as follows; Firstly, 72.1% of the total respondents had the experience of purchasing Han-gwa. Gangjeong was the most popular item among purchased. As the purpose of purchasing, holiday gift and snack was on the highest rank. Hypermarkets / discount stores (48.9%) was the most common place for the place of purchase. Secondly, there was a significant difference in the perception of Han-gwa by age; respondents aged 50 years or older showed more positive perception in Han-gwa in 3 factors among total of 11 factors. Thirdly, for the popularization of Han-gwa, 'too sweet taste (44.2%)' and 'small portion size (22.9%)' were pointed to be improved by respondents. Results of this study indicate that 1) Yu-gwa and Yak-gwa require new product development based on age segmentation, and health and food safety are important variables considered when housewives purchase Han-gwa.

The objectives of this study were as follows: 1) To describe the group of selected disabled homemakers in terms of demographic and medical variables related to organizational activities in the home and family participation in household activities. 2) To identify those demograhpic and medical variables that were related to organizational activities in the home and family participation in household activities. 3) To identify relationship between organizational activities in the home and family participation in household activities. Questionnaires were given to the selected disabled homemakers living in Seoul. The sample was small(N=35) and it was not random; therefore generalizations could not be made to the population as a whole. Data were analyzed by mean, Kruskal-Wallis one-way analysis of variance by ranks, and Spearman rank correlation coefficients. Homemaker's organizational activities were measured by 16 items about physical and mental activities from Mumaw's Organizational Activities Index. Family participation in household activities was measured by 8 items about how often family members participated in two areas of household activities: house chores and extra-activities. The results were as follows: 1) The homemaker's higher organizational activities scores were associated with younger homemaker, higher the level of education, small households, and higher the economic status. The homemaker without children performed better organizational household activities. The homemaker with shorter the duration of disability performed better organizational activities. The homemaker who needed crutches for mobility performed better organizational household activities. 2) The homemaker who was younger, higher the level of education, with smaller households, and lower the economic level was helped by husband. Husband helped better the homemaker with shorter the duration of disability in household activities. 3) Factors affecting children's participation in disabled homemaker's house chores and extra-activities were the age of homemaker and the marital status. The homemaker was single and older, the children were more helpful. 4) Task standardization score was the highest among the factors of homemaker's organizational activities and families with a disabled homemaker participated more extensively than families with abled homemaker. 5) Significant intercorrelation was found between the dependent variables.

Among welfare facilities for the elderly, necessity for the elderly welfare with diverse advantages is rising in the Small-scale Elderly Care Facilities. The government is expecting great demand in the future. However, current the Facilities lack construction plans that consider characteristics of the elderly. Accordingly, 14 case facilities located in JeollaNamdo and Gwangju were selected to comprehensively analyze the circulation of seniors at care facilities by computing spatial depth and visible area variables. As a result of this study, average spatial depth of bathroom, resting room, physical therapy room and dining hall that seniors frequently get in contact with was found to be deep, but visible area appropriate for the function of space was not available. It showed that the circulation for the elderly was deep spatially and long physically, and the spatial rank along circulation which is perceived visually by the admitted the elderly was clear, thus, providing them abundant visual experience supported by high openness as they move from private space to public space. The obtained visibility, however, was observed not to be matched with the function of each space. Since the Small-scale Elderly Care Facilities require various spaces within small surface area, actual functions of each space must be taken into consideration with hierarchical space organization to obtain an environment that stimulates senses such as vision and hearing. In addition, since the circulation of seniors using facilities must consider aging characteristics and delicate care on spatial depth and physical distances, in-depth studies on planning of the circulation in care facilities are deemed necessary.

This study was carried out to provide guidance to environmental policy makers when deciding which assessment fields (biotic, abiotic, qualitative, functional) should have priority for ecological preservation and to develop an objective and scientific methodology by introducing the engineering concept of the fuzzy integral. The grant of weights was used the eigenvalues calculated by factor analysis, and the converted values of indicators were obtained in multiplying the arithmetic values and eigenvalues. The results of the appropriateness and reliability of assessment fields were examined over 0.6, and the results showed that the design of questionnaire presented no great problems. When the fuzzy integral was calculated to determine the rankings at ${\lambda}$=1, 2, 3, 4, 5, respectively, they were 0.646, 0.630, 0.943, 1.423, and 1.167 for the biotic field, 1.298, 1.400, 0.901, 0.580, and 1.456 for the abiotic field, 0.714, 0.674, 0.346, 0.674, and 1.610 in the qualitative field and 1.000, 0.973, 0.943, 1.024, and 1.008 in the functional field. The sensitivity to ${\lambda}$ value showed that ${\lambda}=4$ was the most suitable. In comparison with ${\lambda}=0$ (the arithmetic mean), the range of change was narrow. Because the range for ${\lambda}=4$ was narrower than my other values, ${\lambda}=4$ was sure to be available in ranking-decision. The fuzzy integral is expected to be a method for analyzing and filtering human thoughts. In the future, in order to overcome linguistic uncertainty and subjectivity, other fuzzy integral models including Sugeno's method, AHP, and so forth should be used.
