  • Objective: This study examined cone-beam computed tomography (CBCT)-derived multiplanar-reconstructed (MPR) cross-sections to clarify the salient characteristics of patients with skeletal class III malocclusion with midface deficiency (MD). Methods: The horizontal and sagittal plane intersection points were identified for middle-third facial analysis in 40 patients in the MD or normal (N) groups. MPR images acquired parallel to each horizontal plane were used for length and angular measurements. Results: A comparison of the MD and N groups revealed significant differences in the zygoma prominence among female patients. The convex zygomatic area in the N group was larger than that in the MD group, and the inferior part of the midface in the N group was smaller than that in the MD group for both male and female patients. A significant difference was observed in the concave middle maxillary area among male patients. Conclusions: This study was conducted to demonstrate the difference between MD and normal face through MPR images derived from CBCT. Male patients in the MD group had a more flattened face than did those in the N group. Female patients in the MD group showed a concave-shaped lower section of the zygoma, which tended to have more severe MD. These findings indicate that orthognathic surgery to improve skeletal discrepancy requires different approaches in male and female patients.

  • This Study is a thesis presenting handicrafty and decorative textile design as well as sensual fashion design through the works of Gustav Klimt. The result is as below; The formative qualities in the works of Klimt could be featured as decorativeness, sensuality and symbolism. First, the decorative inclination is prominent in the portrait and the effect is maximized with the golden mosaic shape expressed on the dress and the background influenced by the Byzantine. Second, the sensuality could be recognized directly from the women's pose or facial expression in the works of Klimt, otherwise appeared on the refined expression showed on the portraits of noble lady Third, to surpass the reality, Klimt preferred the symbolic expression, which can be shown on the patterns in the works addressing the themes such as the legends and myths, or figures of men and women expressed with the image of an abstract features of membrum. The development of the textile design is as fellowed. First, it analyzes and reconstitutes the formativeness and the element of design in the works of Klimt by the flow of the form factor. Second. it makes a pattern of a single nature through perception, analysis, description and drawing and expresses with realization of the characteristics of Klimt. Focusing on the handicrafts and decorativeness out of the latest trends and making the most use of the sensuality, the designed textiles were completed by the handicrafty techniques, used in the fashion design and completed as the design of sensual images. The textile development aims at minimizing the limit of design that can be caused by the absence of silhouette and detail, expanding the range of its creativity of fashion designs and creating fashion design high value-added.

  • 청각장애 아동은, 듣고 발화하는 과정을 통해 언어를 재구성해가는 건청 아동과는 달리, 청력의 손실로 인해 언어 습득의 선천적 메커니즘이 작용될 수 없다. 따라서 청각장애 아동의 언어능력 향상을 위해 웹 기반 언어학습 시스템은 이들의 언어학습 특성에 적합하게 구성되어야 한다. 청각장애 아동을 위한 웹 기반 언어학습 시스템을 설계할 때 동작이나 상황을 나타내는 말을 동적으로 구현하고, 사물 및 행동에 대한 관찰력을 증진시킬 수 있도록 주도적인 상황언어학습의 시스템 구성이 필요하다. 그리고 대체사고전략의 활용과 얼굴표정의 강조, 반대어와 대비어의 활용이 시스템 구성에 적용되어야 한다. 이 연구에서는 청각장애 아동의 문법적 오류의 감소와 언어학습의 향상을 도모할 수 있도록 이들의 특성에 적합한 언어학습 시스템을 제안한다.

  • Objectives The purpose of this study was to investigate the relationship between osteoporosis and cardiovascular risk factors according to Sasang constitution. Methods A total of 1773 participants, over 40 years old, were examined as part of a community-based cohort in Wonju city in Gangwon province of South Korea, from June 2006 to August 2009. We measured bone mineral density by Achilles ultrasonometer, serum levels of lipids, fasting blood sugar, insulin and other cardiovascular risk factors like blood pressure and waist circumference. Constitution was verified by a Sasang constitution specialist using the results of PSSC(Phonetic System for Sasang Constitution), facial photos and a simplified Sasang constitutional questionnaire. Results The prevalence rate was 11.2% in total participants, and 10.6% in Soyangin, 10.4% in Taeeumin and 13.9% in Soeumin. In general characteristics, educational and economic property and exercise were concerned with osteoporosis. Systolic blood pressure, pulse rate and total cholesterol were significantly high in osteoporosis group. Age and menopause were the key risk factors for osteoporosis. There was a significantly high prevalence in Soeumin for osteoporosis in men alone. Low physical activity was a major risk factor for osteoporosis. Waist circumference and hip circumference had significantly high odds ratio and weight had significantly low odds ratio. By Sasang constitution, Soyangin has the negative correlation with free fatty acid, Taeeumin has the negative correlation with waist circumference, pulse rate, systolic blood pressure, total cholesterol and low density lipoprotein and Soeumin has the positive correlation with body fat amount. Conclusions Regimens on osteoporosis should be considered according to Sasang constitution. Cardiovascular diseases should be considered according to Sasang constitution. Soeumin should be cautious of osteoporosis and gain weights and reasonable amount of fat food. Soyangin had better do exercise lower body and eat little food containing triglyceride. Taeeumin had better lose weights and eat little cholesterol food.

  • Large oral defects following tumor resection pose formidable challenge for the reconstructive surgeon. Ideally, wound closure should utilize like tissue in providing expedient, single-stage closure, returning maximum function while minimizing deformity. Recent methods have reported and utilize variable mucocutaneous flaps. However, the ideal reconstruction has yet to defined. The small bowel serves as a readily available donor site for satisfying reconstructive needs in oropharyngeoesophageal defects. Segments of jejunum may be opened along the antimesenteric border and transferred to oral defect as free tissue transfers. Some of the benefits of this technique have included a one-stage procedure, abundant donor tissue with characteristics similar to oral mucosa, near normal facial appearance, preservation of maximum tongue function and relief of annoying xerostomia by jejunal mucous secretion. Three cases re presented in which two cases show successful use of this flap. The other one patient developed total necrosis of this flap. We report cases of reconstruction using free jejunal flap transfer in oral reconstruction.

  • BIPV system is one of the best ways to harness PV module. The BIPV system not only produces electricity, but also acts as a building envelope. Thus, it has the strong point of increasing the economical efficiency by applying the PV modules to the buildings. Bifacial solar cells can convert solar energy to electrical energy from both sides of the module. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial soalr cells. Therefore, many of the module manufacturers can easily produce the bifacial solar cells without changing their manufacturing equipment. Moreover, bifacial BIPV system has much potential in building application by utilizing glass to glass structure. However, the performance of bifacial solar cells depends on a variety of factors, ranging from the back surface to surrounding conditions. Therefore, in order to apply bifacial solar cells to buildings, an analysis of bifacial PV module performance should be carried out that includes a consideration of various design elements, and reflects a wide range of installation conditions. As a result it found that the white insulation reflector type can improve the performance of the bifacial BIPV system by 16%, compared to the black insulation reflector type. The performance of the bifacial BIPV was also shown to be influenced by inclination angle, due to changes in both the amount of radiation captured on the front face and the radiation transmitted to the rear face through the transparent space. In this study is limited design condition and installation condition. Accordingly follow-up researches in this part need to be conducted.

  • Purpose: Holoprosencephaly(HPE) is a rare developmental defect due to incomplete cleavages of the prosencephalon during the third week of fetal development. Chromosomal anomalies, genetic syndrome, teratogen, or genetic disorder of non-syndromic HPE are usually accepted as etiology. The consequences of prechordal mesoderm defect are varying degrees of deficit of midline facial development, especially the median nasal process(premaxilla), and incomplete morphogenesis of the forebrain. We experienced a case of lobar HPE with complete cleft lip and palate. Methods: A female newborn infant was born at $38^{+6}$ weeks' gestational age via NSVD. The infant's birth weight was 3.6 kg, height 52 cm, and head circumference 32.5 cm, showing microcephaly, flat nose, median complete cleft lip & palate, and hypotelorism, along with defects of midfacial development including losses of premaxilla, philtrum, nasal septum, and columella. Results: There were no specific findings noted from the head and neck X-ray and tests for endocrine and metabolic disorders, but clinical characteristics of midface and dysgenesis corpus callosum on brain MRI were seen, so that this case was diagnosed with HPE. Conclusion: HPE is divided into three categories of alobar, semilobar, and lobar prosencephaly according to the degree of cerebral hemisphere separation. Assesment of patient's brain abnormality and malformation is essential in determining the extent and benefit of surgical intervention. This case was included in the lobar type HPE which shows relatively good prognosis compared with other types and reconstruction of median complete cleft lip & palate and midfacial defects will be performed.
