Purpose : On outpatient facilities, our sedation protocol focuses on the intermittent bolus injections of midazolam intravenously, according to patient's and operator's needs during the dental treatment. This multicenter retrospective study was aimed to prove the efficiency and safety of our sedation protocol. Patients and Methods : In three centers using the same outpatient sedation protocol for dental treatment (Division of Oral and Maxillofacial Surgery/Department of Dentistry in Hanyang University Medical Center, S-plant Dental Hospital. and Grand Oral and Maxillofacial Surgery), total 937 patients had various dental treatments under intravenous conscious sedations with independent patient monitoring from March 2006 to March 2009. By reviewing charts, we analyzed the results of sedation and dental treatment, retrospectively. Results : Our sedation protocol had no severe postoperative complications requiring admission. while showing good compatibility with almost all dental treatments, with acceptable satisfaction of both patients and operators. Conclusion : We assure that our sedation protocol can be used efficiently and safely on routine outpatient basis. We also hope that this study will provide the concrete concepts to common dental practitioners, who desire to perform sedation for dental treatment.

Objectives : The region of chromosome 5p14 is known to be associated with autism spectrum disorder (ASD). The cadherin9 (CDH9) and cadherin10 (CDH10) genes are located in the region of chromosome 5p14 and reported to be associated with ASD in the Caucasian population. We performed an association study to identify if single nucleotide polymorphisms (SNPs) located on the CDH9 and CDH10 genes are associated in the Korean population. Methods : Genomic DNA was extracted from the blood of 214 patients with ASD and 258 controls. SNPs selected from two genes were genotyped using an Illumina Golden-Gate Genotyping assay with VeraCode technology. Statistical analysis was performed using SAS and Plink software. Results : All controls and ASD patients were in Hardy-Weinberg equilibrium. In the results of logistic regression analyses for the genotype model and the chi-square test for the allele model, we found that SNPs on the CDH9 and CDH10 genes were not associated with ASD. Conclusion : Our data suggests that the CDH9 and CDH10 genes are not associated with ASD in the Korean population.

Objectives : Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by abnormalities of social functioning, communication and behavior. The association of the 7q21-34 region with ASD has been reported. The DLX6 gene, which is located at the 7q22 region, is one of the positional and functional candidate genes for ASD. We found that there is no association between DLX6 polymorphisms and ASD in the Korean male population. Methods : We selected three single nucleotide polymorphisms (SNPs) that might be implicated in the change of the DLX6 gene expression. The genomic DNA was collected from the venous blood of 147 male controls and 179 male patients with ASD. The genotypes of the selected SNPs were determined using the Illumina GoldenGate assay, and the statistical analyses were performed using HapAnalyzer software and SAS Enterprise. Results : We found no association of the three SNPs in the DLX6 gene with ASD in the Korean male population. Conclusion : Our study suggests that the three SNPs in the DLX6 gene are not associated with ASD, and we need to analyze the previously reported regions for their associations with ASD.

This study analyzes the process of growth of Busan from a fishing village to the capital city of South Gyeongsang Province and the central city of transportation and commerce, and an industry with records. The results of the analysis are as follows: after the port opened in 1876, there has been a decline in settlement spaces in Dongnae; on the other hand, there has been an increase in migration spaces around the port of Busan. Waegwan (倭館) nearby Yongdusan Mountain (龍頭山) was changed to the Japanese concession; thus, the number of Japanese moving into Busan had rapidly increased. As a result, the Japanese government carried out reclamation work for securing available lands for the construction of port facilities and other facilities. The Japanese government built public offices and houses, as well as production facilities for daily necessities around the port of Busan. The opening of the Seoul Busan railway (京釜線) and the cross-channel liner between Busan and Shimonoseki (釜關連絡船) led to the growth of Busan and the development of its status. At this time, as the main industry of Busan was trade, Busan had grown as a commercial city. As Busan had grown as a central city of transportation and commerce, the provincial government building of Gyeongsangnam-do (慶尙南道) moved to Busan. Thus, Busan became the central city of local politics and administration. After the Land Survey Project, a large scale of farmers were recruited for low-wage work in the new port. Because of the abolition of the corporation law, Japanese capitalists moved into their colony in Busan. There, large-scale factories, such as the Joseon cotton textile factory, were established. Through this process, the locality of Busan was changed from a fishing village to a commercial city and, finally, to a city of commerce and industry.
We present a trade-off technique for fast but qualitative planar shape deformation using a layered mesh. We construct a layered mesh that is embedding a planar input shape; the upper-layer is denoted as a control mesh and the other lower-layer as a shape mesh that is defined by mean value coordinates relative to the control mesh. First, we try to preserve some shape properties including user constraints for the control mesh by means of a known existing nonlinear least square optimization technique, which produces deformed positions of the control mesh vertices. Then, we compute the deformed positions of the shape mesh vertices indirectly from the deformed control mesh by means of simple coordinates computation. The control mesh consists of a small number of vertices while the shape layer contains relatively a large number of vertices in order to embed the input shape as tightly as possible. Since the time-consuming optimization technique is applied only to the control mesh, the overall execution is extremely fast; however, the quality of deformation is sacrificed due to the sacrificed quality of the control mesh and its relativity to the shape mesh. In order to change the deformation behavior and consequently to compensate the quality sacrifice, we present a method to control the deformation stiffness by incorporating the orientation into the user constraints. According to our experiments, the proposed technique produces a planar shape deformation fast enough for real-time applications on limited embedded systems such as cell phones and tablet PCs.
The present study aimed to identify the effects of the trunk stability exercise on functional movement, dynamic balance, and trunk stability in patients with chronic low back pain, and to compare the difference among yoga exercise, pilates exercise and core exercise. Forty-three patients with chronic low back pain were divided into three groups; 15 yoga groups, 15 pilates groups, and 13 core exercise groups. All subjects were tested the Functional movement, dynamic balance, and trunk stability using Functional Movement Screen (FMS), Lower Quater Y-Balance Test (YBT-LQ) and Trunk Stability Test (TST), respectively, and after each 8-week exercise program was applied, all variables were retested. After exercising during 8 weeks, FMS, YBT-LQ and TST scores of all three groups were significantly improved, compared to before, but there were no interaction effect among three groups depending on application of exercise program. These results showed that yoga, pilates and core exercise help to improve functional movement, dynamic balance and trunk stability in adults with chronic low back pain.

Increasing the oxidation of fat through exercise is the recommendable method for weight control. Preceding researches have proposed increase in the usage of fat during exercise in stabilized state and under maximum exertion through aerobic training. However, such researches require additional equipment for gas analysis in order to measure the caloric value or gas exchange of subjects during exercise. Such equipments become highly restrictive for those exercise and cause substantially higher cost. According to this, we have presented the method of estimating the maximal fat oxidation point through changes in LF & HF which reflects changes in heart rate and the autonomic nervous system in order to induce exercise for a less restrictive and efficient fat oxidation than existing methods. We have conducted exercise stress test on subject with similar exercise abilities, and have detected the changes in heart rate and changes in LF & HF by measuring changes in fat oxidation and measuring ECG signals at the same time through a gas analyzer. Changes in heart rate and HRV of the subjects during exercising was detected through only the electrocardiographic signals from exercising and detected the point of maximum fat oxidation that differs from person to person. The experiment was carried out 16 healthy males, and used Modified Bruce Protocol, which is one of the methods of exercise stress test methods that use treadmill. The fat oxidation amount during exercise of all the subjects showed fat oxidation of more than 4Fkcal/min in the exercise intensity from about 5 minutes to 10 minutes. The correlation between the maximal fat oxidation point obtained through gas analysis and the point when 60% starts to be relevant in the range from -0.01 to 0.01 seconds for values of R-R interval from changes in heart rate had correlation coefficients of 0.855 in Kendall's method and in Spearman's rho, it showed significant results of it being p<0.01 with 0.950, respectively. Furthermore, in the changes in LF & HF, we have determined the point where the normalized area value starts to become the same as the maximal fat oxidation point, and the correlation here showed 0.620 in Kendall and 0.780 in Spearma of which both showed significant results as p<0.01.
The purpose of this study is to provide necessary information to understand characteristics of vocational high school students and to enhance academic engagement through social support of teachers, leading to help research of teaching and learning strategy. A survey was conducted on 990 engineering major students attending 11 vocational high schools in Seoul metropolitan, Chungcheong, Jeolla, Kyeongsang and Kangwon regions. A questionnaire consists of measurement tools for the academic engagement (21 questions) and the social support of teachers (25 questions). The findings of this study are as follows: First, it is found that the level of students' academic engagement was high. But it appears that the students showed low engagement of emotion compared with that of behavior and cognition. There was no level difference according to gender, but there was a considerable difference according to a school year. The first year students' level of engagement was higher than the second and the third year students' in terms of cognition and emotion. Second, it shows that the level of the teachers' social support was normal, which was in the order of appraisal support, instrumental support, informational support, and emotional support. Especially, the level of appraisal support and instrumental support was most. Third, there were correlation and explanation between students' academic engagement and teachers' social support. Moreover, the result that teachers' emotional support has high correlation and explanation in qualitative terms of academic engagement support the importance. Therefore, it is concluded that the social support of teachers can make an positive influence on improving the academic engagement of students and provide students with adaptability and satisfaction with their school life, which may give students a positive effect in emotional development, self-formation, and complement.

It is a important problem that the adjustment of a rural settlementas a unit of rural community, and many number of researcher tackled its. The aim of this paper is to verificate the process of rural con-struction, that is applied the regional resources, and to introduce the situation of attending inhabitants, and their employments as a results of this planning. We chose Odaira hamlets in Oomama town, it is located in Gunma prefecture as an object of this study. Odaira is a small village in the mauntain, and it is composed only 135 families. Odaira is an underpopulated hamlet. It is engaged no lively farming and forestry. Most of inhabitants are commuting to the cities around here. Inhabitants of Odaira who are conscious of the conditions of declining hamlet organized a group to improve it. This group have investigated all around the hamlet as a system of workshop. And they found the resources for sight-seeing, crops as the regional products, and other resources for rural planning under three keywords ; resources for the sight-seeing, the rigional products, and theimprovement of environments. In many resources, most important thing was the existens of a stalactite cave come down as a legend from old time. Local government of Oomama town and the inhabitants tried to explorate of stalactite cave and succesed to excavate it. They have constructed two facilities for management, parkaround the stalactite cave and these have been a new place of work for inhabitants. Arrangement of the rural constructions developed to other items schemed acording to the master plan, like as a camping ground, bungalows, a wet botanical garden, and a park beside a river. These also produced the new places of work for 54 people as a result of this rural planning. The most of them were the aged peoples and the women of farmer. The highest age was 83 years old, he is working at the camping ground. In the employment system at Odaira, people who desire to work and desire to employ both registrate to a commission of management of Odaira, and this commission arrange them in case of needs.
