Objectives: The outcomes of the treatment of unilateral cleft lip can vary considerably due to variations in repair techniques. The aim of this study was to evaluate and compare treatment outcomes of surgical repair of unilateral cleft lip using either the Tennison-Randall or Millard technique based on (qualitative) parent/subject and professional assessments. Materials and Methods: This was a prospective, randomized, controlled study conducted at Lagos University Teaching Hospital between January 2013 and July 2014. A total of 56 subjects with unilateral cleft lip presenting for primary surgery who satisfied the inclusion criteria were recruited for the study. Subjects were randomly allocated to surgical groups A or B through balloting. Group A underwent cleft repair with the Tennison-Randall technique, while group B underwent cleft repair with the Millard rotation advancement technique. Surgical outcome was assessed using qualitative evaluation by the guardian/subject and independent assessors based on a modified form of the criteria described by Christofides and colleagues. Results: Of the 56 subjects enrolled in this study, 32 were male, with a male to female ratio of 1.3:1. Fifteen of the guardians/subjects in the Tennison-Randall group were most bothered about the lower part of the residual lip scar, while 12 guardians/subjects in the in the Millard group were most bothered about the upper part of the scar. More noses were judged to be flattened in the Millard group than in the Tennison-Randall group. Assessors observed a striking disparity in scar transgression of the philtral ridges between the two groups. Conclusion: Essentially, there were no major difference in the overall results between Millard rotation-advancement and Tennison-Randall repairs. Both Millard and Tennison-Randall's techniques require significant improvements to improve the appearance of the scar on the upper part and lower part of the lip, respectively.

This study was attempted to promote changes in traditional design education at a time when non-face-to-face education is necessary, such as digitalization, rapid social structure change, and post-COVID-19 situations, and to meet the demands of the times when user-centered design is more emphasized. Therefore, the goal of this study is to explore the process of developing mobile apps and operating education for deaf learners through design thinking-based interaction design education for design students. Specifically, the curriculum was designed by selecting a design thinking methodology suitable for major students to experience empathy and solutions to user problems. The subject that students majoring in this study want to sympathize with is deaf learners, and the subject of the curriculum is the development of educational support applications for deaf learners. Accordingly, a mobile app prototype that can support online learning for deaf learners was created based on the interaction design education plan designed based on design thinking. In addition, after collecting and analyzing the feedback of deaf learners to evaluate the prototype effectiveness, the final mobile app prototype was presented as an output. Through this process, interactive design education based on design thinking helped to strengthen the ability to empathize with and solve the needs of deaf learners to major students and improve the design learning experience. Based on these findings, if a methodology suitable for various user groups is selectively accepted for design education, the students in the major will have the ability to design by prioritizing the actual needs of users despite changes in the environment of the future design society.

The purpose of this study was to identify factors associated with high satisfaction with foodservices in family restaurant. Accordingly, this study surveyed questionnaire concerning 20 measures of foodservice as well as major subject descriptors. The result of this study were as follows. KMO and Bartlett's test statistics showed that the data fitted factor analysis well. Results of factor analysis, average variance extracted estimates and shared variance showed that the convergent and discriminant validitys of 3 factors are supported, and cronbach's alpha showed that the internal consistency of 3 factors is supported. It was found that expensive groups, except gender groups and frequency of purchase groups, were differentially associated with high levels of overall satisfaction with foodservices. Multivariate analyses showed that satisfaction with service factor was the best predictor of overall satisfaction, followed by facilities factor. Three factors emerged from the logistic regression analysis as predictors of level of overall satisfaction. Overall, approximately 77% of university students could be correctly classified as being satisfied or unsatisfied. Finally, the results of the study provide some insights into the market-oriented types of foodservice marketing strategies or tactics to enable family restaurant to effectively manage and more competitive.

The purpose of this study was to analyze elementary school teachers' implementation for the emphasis on the revision, major contents, teaching and learning method, and evaluation in the 2009 revised national science curriculum. To fulfill the purpose of this study we carried out a survey with 222 elementary school teachers. Main findings of this research were as follows: First, they highly agreed to the increase in class hours and the application of subject classroom, but they had a lower recognition for setting the subject groups. Second, the degree of necessity in discussion and STS was relatively high, but the degree of implementation in science writing, discussion and STEAM was low. Third, in teaching and learning method, they showed a high performance for mutual cooperation, student-led activities and communication, but, a low implementation for open inquiry and instruction considering individual differences. Fourth, in the evaluation of science learning, they showed a high implementation for evaluation based on achievement standards and one based on the understanding and application of basic concepts, but, a low implementation for the development of common evaluation tools. Fifth, it seemed that their recognition for amount, level and interest of science contents and inquiry activities was appropriate and positive.

This study identified cognitive styles of online searchers in terms of Field Dependence (FD) and Field Independence (FI) dimension and determined whether searching performance was affected by FD / FI cognitive differences between online searchers and the extent to which searching performance was affected by the FD / FI dimension of cognitive style. This study used a quasi experimental design with 41 student subjects using the Lockheed DIALOG system and ERIC ONT AP database. Cognitive styles of student subjects were measured by using GEFT (Group Embedded Figure Test) and the subjects were divided into two cognitive groups- FD and FI based on the GEFT scores. Each subject was assigned two predetermined searches which had different search goals-a 'high precision search' and a 'high recall search.' Search performance of the two cognitive groups on the two problems was compared in order to see how these two groups responded to achieving different search goals in terms of search strategy, search inputs, and resulting search outputs. The major findings of this study were: 1. The pattern of approaching a search problem regardless of whether it was a high precision search or a high recall search was not significantly different between the two cognitive groups. 2. The FI group tended to use significantly more terms for the high recall search than the FD group but slightly less time than the FD group. However, significant differences in connect time between the two groups were not revealed. 3. For both search problems the FI group achieved a significantly higher success rate than the FD group. The FI group were significantly more successful searchers than the FD group. As for unit / cost, although the FI group were more cost effective than those of the FD group for both searches, these differences were too small to be statistically significant. 4. Mean differences of the search performance variables between the FD / FI groups were consistent across the two types of search questions. The FI group seemed to be equally effective for both types of search questions. In conclusion, the differences found in number of terms used and success rate between the two cognitive groups apparently resulted from different cognitive styles.

Purpose. The purpose of this study was to compare the effects of various surface treatments by measuring resonance frequency and histomorphometric analyses. Material and methods. In 5 adult dogs, the mandibular premolar were extracted. Six months later, 30 screw titanium implants (Dentium Co., Seoul, Korea) 6mm in length and 3.4mm in diameter, were placed in the mandibles of 5 dogs. Implants were divided into five groups following to surface treatment methods ; Group 1 is machined controls, Group 2 is sandblasted with large grit and acid-etched (SLA), Group 3 is anodized (Autoelectric Co., Korea, 660Hz, Duty10), Group 4 is hydroxyapatite(HA) coated by ion beam assisted deposition(E-beam), Group 5 is hydroxyapatite(HA) coated with Sol-gel coating process. Resonance frequency was measured implant placement immediately, and 3, 6 weeks and 10 weeks of healing perods. With the animal subject's sacrifice 10 weeks after implantation, implants were removed on bloc and histologic and computer-based histomorphometric analyses were performed. Histomorphometric analysis involved quantification of the entire bone to metal contact around the implants. Statistical analyses were performed using the SPSS for Windows (ver. 9.0 SPSS Inc.) Statistical differences were considered significant at P<0.05. Results. The results were as follows : 1) In five groups, mean value of resonance frequency analysis(RFA) were highest in group 5 (Sol-gel implant) at implantation and those of group 4 (E-beam)was highest at 10 weeks . but there was no correlation between surface treatments and RFA. 2) In all surface treatment groups, the RFA values of implants decreased until 3 weeks and increased to 10 weeks. 3) The percentage of direct bone-to-implant contact (BIC) had statistical significance between five groups in cancellous bone, (P<0.05) the percentage of bone density inside the thread had no statistical significance between five groups. (P>0.05) 4) There was a significant difference between cortical bone and cancellous bone in BIC. (P<0.05) and bone density. (P<0.05) 5) There was a correlation between the RFA value of implants at 10 weeks and BIC in cancellous bone, and between the RFA value of implants at 10 weeks and bone density in cortical bone. (P<0.05). Conclusions. These results indicate that surface treatment does not affect the implant stability in case of good bone quality.
