Objectives : this study is to see if there is a significance in thermal differences of acupoints in diagnosis and treatment period of facial paralysis and to substantiate the validity of acupuncture and moxibustion treatment for it. Methods : 1. By using DITI, thermal differences of acupoints on the face and the upper limbs of 13 Bell's palsy patients were measured around 3 days after an attack of the disease. These 13 patients, whose treatment progress was monitored up to 6 months after attack, were among the inpatients and outpatients of oriental internal medicine of National Medical Center from July 1 to August 31. 2. The patients were divided into 1month, 2-3months, 4months, 6months groups according to the occasion of improvement and thermal averages of each treatment period measured. Results : When it takes within 1 month for the condition of facial paralysis to change for the better, DITI image shows the temperature of the affected face parts and arms is higher than that of the non-affected parts. However, when it takes more than 4 months, the temperature of the affected face parts and arms on DITI image is lower than that of the non-affected parts. Conclusions : Hereby, prognosis of the disease and necessary time for the treatment can be presumed through DITI screening after an occurrence of facial paralysis. Also, condition of the disease is reflected by thermal differences of acupoints for Bell's palsy treatment that are in accordance with the theory of meridian on the face. This supports the efficacy of acupuncture and moxibustion treatment for this disease.

The purpose of this study is to determine affects of hair colors on physical shapes and images through field survey and experimental research. For the purpose, this researcher surveyed 230 female college students residing in Busan about their dyed hair colors, and selected the subjects for the study. Then the researcher an experimental research on the subjects by suing test stimuli. Results of the study can be described as follows: Experiment of the Optical Illusion of Physical Shapes. For all items measured for the experiment, except four ones, if was found that hair colors provided significant efforts of optical illusion factor analysis, included horizontality, outlines of the body and face, a horizontal line of the shoulder, the length, verticality and a horizontal line of the face. According to hair colors, black made the body look slimmer and the face look apparent. White made the body height look low, the outline of the face look clear and the neck or shoulder look fleshed. Female college students whose hair color was orange looked unclear in the body silhouette, bright in the face and broad in the hip and shoulder. Other students whose hair color was red, attracting the line of vision upward most strongly, looked fleshed in the upper body and broad in the face. Finally, blue made the face look dark.

Based on the results of Han et al. (2016), in the failure zone ahead of the tunnel face it can be obviously identified that a shear failure band occurs in the lower part and a pressure arch happens at the upper part, which was often neglected in analyzing the face stability of shield tunnel. In order to better describe the collapse failure feature of the tunnel face, a new improved failure mechanism is proposed to evaluate the face stability of shield tunnel excavated in layered soils in the framework of limit analysis by using spatial discretization technique and linear interpolation method in this study. The developed failure mechanism is composed of two parts: i) the rotational failure mechanism denoting the shear failure band and ii) a uniformly distributed force denoting the pressure arch effect. Followed by the comparison between the results of critical face pressures provided by the developed model and those by the existing works, which indicates that the new developed failure mechanism provides comparatively reasonable results.

PURPOSE: The purpose of this study was to investigate the quality of life related to fall experiences in chronic stroke patients. METHODS: This cross-sectional study included 117 patients with stroke from 3 hospitals in D metropolitan city. General characteristics, including fall experiences and quality of life, were assessed through a face-to-face interviews conducted in a quiet place using a questionnaire. Measurement of quality of life in stroke patients was conducted using the Korean Stroke Specific Quality of Life Scale (SS-QOL). To identify the SS-QOL items related to fall experiences, the items of the SS-QOL were considered as independent variables, and the variables that were significantly different according to fall experiences were identified using a univariate analysis. A binary logistic regression was then performed using fall experiences as the independent variable. RESULTS: According to the univariate analysis, self help activities, social role, and upper extremity function were significantly lower in the fall group than that in the non-fall group (p<.05). The findings of the binary logistic regression confirmed that social roles and upper extremity function were the SS-QOL items that were related to fall experience in chronic stroke patients. CONCLUSION: These findings suggest that social roles and upper extremity function may be risk factors for fall experience in patients with chronic stroke.

The purpose of this study was to find out what changes in weight bearing in the both upper extremities occurred in response to Asymmetrical Tonic Neck Reflex by rotation of head in the quadruped position. The subjects for the study were 80 children (44 male, 44 female) who were neurologically normal. They were divided into two groups $6\~7$ year olds and $8\~9$ year olds. Paired t-test was applied as a atatistical method at the 0.01 level of significance. The results of this study are as follows; 1. In the neutral position of head, there was mort weight bearing on the left hand than the right in both of the two groups(p<0.01). 2. When the head was rotated to the right or left passively, there was more weight bearing on the hand of side to which the face was rotated(p<0.01). 3. When the head was rotated to the right or left actively, there us also more weight bearing on the hand of side to which the face was rotated(p<0.01). Therefore, it is possible to un Asymmetrical Tonic Neck Reflex to increase body weight for muscle strengthening in children with weakened muscles of the upper extremities. further studies are required for confirmation of these findings.

The conventional treatment of skeletal Class III malocclusion has been focused on application of orthopedic force primarily to the mandible. However, In Class III malocclusion with retrograde position or underdevelopment of Maxilla, this approach is not suitable treatment. These patients need an application of orthopedic forces via face-mask to the Maxilla to stimulate its growth and to change the direction of growth. In skeletal Class III patients who were treated by Face-Mask, the following results were obtained. 1. Forward growth of Maxilla was enhanced. 2. Labioversion of upper incisors and linguoversion of lower incisors were observed. 3. Mandible was rotated to clockwise direction and remodeling of B point was observed. 4. Anterior crossbite was corrected by combining of the above results.

Long face patients are characterized by excessive anterior facial height, lip incompetence at rest, anterior open bite, and gummy smile. A major problem is an inferior rotation of the posterior maxilla and upper molars. Long face patients have been the most difficult for orthodontist to treat successfully. In growing patients, the methods for impeding excessive vertical growth have been used high pull head gear, functional appliance, and combined type of two. One significant improvement comes from using a full arch splint to deliver force to the maxilla more vertically. In adult patients, orthodontic camouflage treatment is biomechanically difficult and doesn't work when the problem is primarilly vertical. Surgical maxillary impaction provides a means for successfully treating most of problems. Also, superior reposition of the chin via a mandibular inferior border osteotomy is effective in decrease of lower anterior facial height and correction of the poor chin-lip balance. Post-surgical stability and the physiologic response are good. The coordinated orthodontic and surgical treatment is necessary for solution the difficult skeletal deformity.

Face stability analyses provides the most probable failure mechanisms and the understanding about parameters that need to be considered for the evaluation of ground movements caused by tunneling. After the Upper Bound Method (UBM) solution which can consider the influence of seepage forces and depth-dependent effective cohesion is verified with the numerical experiments, the probabilistic model is proposed to calculate the unbiased limiting tunnel collapse pressure. A reliability analysis of a shallow circular tunnel driven by a pressurized shield in a frictional and cohesive soil is presented to consider the inherent uncertainty in the input parameters and the proposed model. The probability of failure that exceeding a specified applied pressure at the tunnel face is estimated. Sensitivity and importance measures are computed to identify the key parameters and random variables in the model.

This work was undertaken to evaluate the integumental response in lower face to hard tissue changes, and to grope the prediction equation for expected integumental profile changes. Cephalometric headplates of 25 persons consisted of 8 Angle's class 1 maxillary protrusive and 17 Angle's class II division 1 patients whose mean age was 15.2 years were traced, diagramatized, and statistically analyzed. The results were as follows; 1. Upper incisor and lips were retracted and convexity of integumental profile decreased concurrently with decrease of hard tissue procumbency, however soft tissue point A', B', and Pog' did not undergo significant changes after orthodontic treatment. 2. Remarkable increment of upper lip thickness and upper lip height was shown and this was related to upper incisor retraction. The ratio between the amount of upper incisor retraction and the increment o f upper lip thickness was approximately 1.16:1. 3. Moderate correlation of upper lip retraction to upper incisor retraction, and of lower lip retraction to lower incisor movement were arranged, and yet comparatively wide variability from subject to subject was shown. 4. It was possible to predict statistically for horizontal alteration of lip position and change of upper lip angulation ground in orthodontic treatment.
