When open reduction of maxilla fractures is postponed due to concurrent life-threatening injuries, delayed union may result with malunion or nonunion. If delayed malunion is occurred, significant facial deformity may result, including a dished-out face, irregular retromaxillism with Angle's class III malocclusion, open anterior bite, nasal collapse, telecanthus and malar flattening. The treatment planning for this problem includes cephalometric evaluation anterior and lateral tomograms, dental casts, orthodontic planning, dental planning and use of impression tray to rupture the fibrous tissue casts, orthodontic planning, dental planning and use of impression tray to rupture the fibrous tissue attachment at the fracture site. In this paper, one case presented a 58-year-old female patient with maxilla retrusion after comminuted fracture, who was treated with orthodontic methods of maxillary protraction headgear and Plaster headcap, whereas the other two cases were about male patients who were treated principally with surgically open reduction or Le Fort I-controlled transverse osteotomy with iliac bone graft.

Introduction : The Vaginal, the urethra, the vulva and anal cancer avoid the many dose to femur head and the additional treatment is necessary in inguinal LN. The partial transmission block to use inguinal LN addition there is to a method which it treats and produce partial transmission block a method and the MLC which to it analyzes. Material & Methode : The Inguinal the LN treatment patient partial transmission it used block and the MLC in the object and with solid water phantom with the patient it reappeared the same depth. In order to analyze the error of the junction the EDR2 (Extended dose range, the Kodak and the U.S) it used the Film and it got film scanner it got the beam profile. The partial transmission block and the MLC bias characteristic, accuracy and stability of production for, it shared at hour and comparison it analyzed. Result : The partial the transmission block compares in the MLC and the block production is difficult and production hour also above 1 hours. The custom the block the place where it revises the error of the junction is a difficult problem. If use of the MLC the fabrication will be break and only the periodical calibration of the MLC it will do and it will be able to use easily. Conclusion : The Inguinal there is to LN treatment and partial transmission block and the MLC there is efficiency of each one but there is a place where the junction of block for partial transmission block the production hour is caught long and it fixes and a point where the control of the block is difficult. like this problem it transfers with the MLC and if it treats, it means the effective treatment will be possible.

A 4-year-old male Yorkshire terrier was referred to us with signs of vomiting and unconsciousness due to a blunt head trauma. Gross examinations detected facial edema, subcutaneous hemorrhage and hypersalivation. A survey radiograph located an occipital fragment which was displaced caudally. A three-dimensional computed tomographic reconstruction demonstrated that the ventral portion of the fragment was attached incompletely. Because of the instability of the fragment, it was decided to perform an esquillectomy. After removing the fragment, the defect was reinforced with a muscular flap originating from the splenius muscle. The patient's condition gradually improved except for a slightly ataxic gait. At 20 months follow-up, there was no evidence of ataxia. The neurological status did not deteriorate before starting surgical intervention, although the patient sustained a skull fracture with severe intracranial hemorrhage. It is likely that the fragment being displaced outwardly played an important role in preventing an increase in intracranial pressure which could have led to neurological deterioration.

High dimensional data are frequently encountered in various fields where the number of variables is greater than the number of samples. It is usually necessary to select variables to estimate regression coefficients and avoid overfitting in high dimensional data. A penalized regression model simultaneously obtains variable selection and estimation of coefficients which makes them frequently used for high dimensional data. However, the penalized regression model also needs to select the optimal model by choosing a tuning parameter based on the model selection criterion. This study deals with the bias effect of LASSO regression for model selection criteria. We numerically describes the bias effect to the model selection criteria and apply the proposed correction to the identification of biomarkers for lung cancer based on gene expression data.

Medical color graphic research will serve as the basis for globally expanding and disseminating the design quality of the company's products through the era of production of medical robots. This study was based on technologies and contents suitable for the era of medical robot bed expansion, universal medical color application, ergonomic color, etc. In addition, the medical bed robot's color research direction was presented from the perspective of universal design. Accordingly, a universal color design was proposed, taking the functions of a medical robot under development by a domestic company as an example. The characteristics of this robot bed can be divided into three types of functions: first, treatment characteristics for prevention of pressure ulcers with curative, second, automatic seat exchange with cleanliness for medical environment, and third, Convenient, which can implement patient transport. The main idea is to present a combination of functional colors appropriate for this. The resulting color analysis and universal color design techniques could be a useful methodology for illustrating the appearance and function of a modern medical robot bed.

최근 의료시장에 상용화된 모바일 수술 중 CT(intra-operative computed tomography, iCT)는 수술실 내 이동이 자유로울 뿐만 아니라 수술 후 즉각적인 환자 모니터링이 실시간으로 이루어져 수술 후 환자의 예후 향상과 재수술 확률을 낮출 수 있다. 이동성을 갖춘 iCT 는 편의성과 유용성이 검증되었지만, 이동시 발생될 수 있는 충돌사고의 단점이 존재한다. 따라서, iCT 의 이동시 발생할 수 있는 위험을 최소화 할 수 있는 안전장치가 요구된다. 본 연구에서는 모바일 iCT 의 구동 제어의 편의성과 안전성을 확보 할 수 있는 CT 촬영을 제어하기 위한 리모트 컨트롤러, 이동시 전방 시야를 확보하기 위한 전방 모니터링 카메라 출력, 충돌 위험을 알릴 수 있는 초음파 센서를 통합하는 임베디드 컨트롤러를 개발하고자 한다.

One of the most important things for hospital managements is understanding the patients' needs. The aim of this study is to analyse the priorities of the factors influencing patients' choice for hospital with analytic hierarchy process (AHP), which can derive the relative importances of factors. With understanding the factors that influencing patients' choice for hospital, the proper methods to improve hospital reputation and health care quality could be determined. Among 12 factors, speciality of hospital, number of departments, staff kindness, doctor-patient communication, and patients' visit time were relatively more important and higher priority. Whereas, public transport accessibilities, hospital equipments, and parking lots were relatively less important and lower priority. These results could be used to improve hospital reputation and health care quality effectively. Therefore, the hospitals in Gwangju should consider the factors that influencing patients' choice and improve policies for hospital marketing strategies for better hospital reputations and health care quality.

The present study explored factors that influence consumers' benefit expectancy about telemedicine service. Responses from a national online survey of 927 adults (aged 19-59), collected in January 2016, were analyzed with multiple regression analysis. The results revealed: (1) Health consciousness positively influenced all three benefit expectancies (all ps < .05); (2) Doctor-patient communication efficacy positively influenced expectancy for convenience improvement (${\beta}=.107$, p < .01) and service quality improvement (${\beta}=.086$, p < .05); (3) Use of health-related smart applications contributed to positive expectancy for service quality improvement (${\beta}=.081$, p < .05) and cost-saving (${\beta}=.067$, p < .05). Some of the relationships were moderated by gender and residence. This convergence study, which examined public's perception about telemedicine from the perspectives of consumer psychology, media, and public health, provides practical implications to promote telemedicine service and educate consumers about it.

Breast cancer is the most prevalent oncological disease among women. Various psychosocial distress is common at the diagnosis, treatment, and posttreatment phase of breast cancer. For the treatment of breast cancer, not only medical treatment but also psychosomatic integrative care will be needed. Patients with breast cancer may lead to increased vulnerability to stress, adjustment disorder, anxiety disorder, and depressive disorder, and these psychiatric diseases and conditions are associated with recurrence or exacerbation of breast cancer. Psychosocial treatment of anxiety and depression could increase the quality of life of patients and decrease the recurrence and progression of breast cancer. In this article, we reviewed 5 clinical breast cancer survivorship guidelines focused on psychosomatic integrative care including psychosocial treatment and alternative treatment for psychosocial distress. Because 5 treatment guidelines were using various definitions of evidence, we confirmed evidence of various psychosocial treatments for patients with breast cancer based on the definition of evidence by the US Preventive Service Task Force (USPSTF) guideline. We also reviewed the effect size of psychosocial treatment for anxiety, depression, mood, and quality of life in patients with breast cancer. This article discusses the barrier to the delivery of psychosomatic integrative care and suggests integrative care planning for breast cancer. Multi-disciplinary teams, patient's needs assessment, information technology support, patient and caregiver engagement, planned periodic monitoring of psychosocial distress by a psychosomatic specialist or consultation-liaison psychiatrist are recommended as key features of a psychosomatic integrated care plan.
