The purpose of this study was to obtain basic data needed to clinical diagnosis and treatment by investigating the occlusal wear facets and those related factors. Sixty-six subjects, ranging from 24 to 26 years of age without symptoms of stomatognatic system, were selected from dental students in Chosun University. The area of occlusal wear facets was measured and twenty subjects were selected, and divided into two groups (Group I and Group II). The Group I had small facet areas, and the Group II had large facet areas. These two groups were investigated into right and left side wear facet areas, vertical overlaps, occlusion types of working side, masticatory muscle activities, and asymmetry of right and left side masticatory muscle function. The results were as follows: 1. The average wear facet areas of all subjects was $22.84{\pm}88.95mm^2$, and Group I and Group II were $96.12{\pm}32.00mm^2$ and $372.94{\pm}65.63mm^2$ respectively. 2. The right and left wear facet areas of Group I were $46.72{\pm}14.36mm^2$ and $49.40{\pm}21.46mm^2$ respectively. The right and left wear facet areas of Group II were $175.27{\pm}45.75mm^2$ and $185.69{\pm}45.37mm^2$ repsectively. 3. The vertical overlap of Group I and Group II was $3.88{\pm}0.81mm$ and $2.88{\pm}1.14mm $ respectively. 4. Most of the Group I had Canine protection occlusion (80%), and most of the Group II had Group function occlusion (80%). 5. The masticatory muscle activities at rest position, maximum bite, habitual chewing, right and left unilateral chewing were greater in Group II than in Group I, especially in the masseter muscle of working side at right and left unilateral chewing. (P<0.01). 6. The asymmetry of right and left wear facets and masticatory muscle activities were greater in Group II than in Group I. (P<0.01).

Development of de novo dural arteriovenous fistula (DAVF) at a different site after resolution of an initial DAVF, is rare. Here we report two cases, which we encountered in our hospital. A 68-year-old woman presented with pulsatile tinnitus on the left side. Cerebral angiography demonstrated a left anterior condylar confluence (ACC) DVAF and she underwent transvenous embolization. Four years after this treatment, she presented with tinnitus on the left side, and cerebral angiography revealed a right DAVF around the sinus of the lesser sphenoid wing. Another 69-year-old woman presented with left-sided orbital bruits, chemosis, and conjunctival hyperemia. Cerebral angiography showed left cavernous sinus (CS) DAVF, for which she underwent transvenous embolization for CS DAVF. One year later, she developed a left ACC and transverse-sigmoid sinus (TSS) DAVF.

Facial nerve palsy is not an uncommon disease encountered at the department of otolaryngology or pain clinic. It usually occurs following viral infection(Bell's palsy, BP). However, it is rare to develop bilaterally, and that not simultaneously. We experienced a rare case of bilateral facial nerve palsy. Patient first experienced left side paralysis, then right side paralysis approximately two months later. We treated the patient with serial bilateral stellate ganglion blocks(SGB). When left side paralysis improved, we performed unilatertal SGB for right side paralysis. Patient was also treated with intermittent electro-acupuncture stimulations, to right side first, then left side. Four months of treatment provided good results. This may be the first case, in Korea, of facial nerve paralysis bilaterally within a certain interval, treated with serial SGB and electro-acupuncture stimulation. However, the etiology of this bilateral BP was not fully confirmed as being a cause of viral origin.

The relationale for recording mandibular movement is to accurately adjust an articulator. Techniques to record mandibular movement include radiographic interpretation, extraoral tracing, and intraoral recording materials. This study was performed to compare the concylar guidance inclination and Bennett shift(immediate & progressive side shift)obtained by using an electronic pantograph, pantograph and wax interocclusal records in Korean. Ten adults who have normal occlusion and are free of TMJ dysfunction were selected and clutches were constructed. At first Pantronic survey was performed three times by using an kinematic hinge axis according to manufacturer's direction. Next pantographic survey was performed three times and the articulator was adjusted with each pantographic recording. And then maxillary cast was attached to the articulator with pantographic as a face-bow and the mandibular cast was mounted to the articulator with centric relation record. Three protrusive, three left lateral and three right lateral wax interocclusal records were taken on the subjects and the articulator was adjusted with each interocclusal record. Protrusive condylar inclination, lateral condylar inclination, immediate side shift and progressive side shift obtained by using electronic pantograph, pantograph and wax interocclusal record were compared and analized. The results were as follows; 1. The average left and right protrusive and orbiting condylar inclination($33.7^{\circ},\;37.1^{\circ},\;40.6^{\circ},\;43.5^{\circ}$) record with Pantronic was significantly greater than that recorded with other methods. 2. The average left and right protrusive and orbiting condylar inclination($24.8^{\circ},\;27.0^{\circ},\;31.4^{\circ},\;32.4^{\circ}$)recorded with wax interocclusal record was less than that of other methods. 3. The average left and right immediate side shift(0.57mm,0.44mm)recorded with wax interocclusal record was greater than that of other methods and the average left rigtht immmediate side shift(0.30mm,0.41mm)recorded with Pantronic was significantly greater than that recorded with pantograph(0.11mm,0.20mm). 4. The average variance of wax interocclusal was signivicantly higher than that of other methods.

Authors was experienced a case of mucocele in the left frontal sinus. A 24-years-old Korean male soldier was admitted to C.A.F.G.H. on 16th May 1980, with chief complaints of dull headache, exophthalmos, visual disturbance and intermittent epistaxis on the left side. On physical examination, left turbinates and septum were revealed hyperemic middle turbinate with blood tinged spots and deviated slightly to right side, and felt round, smooth, rubbery painless swelling within the orbit at the left inner canthus. The left orbital contents was displaced laterally producing proptosis with diplopia. On the radiological examination, Caldwell and Water's view showed hazy density in medial side of left orbital and left frontal sinus. Tomography of orbit showed hazy increased mass density with rather sharply defined outer margin of left bony orbit probably due to compressive erosion. The case was treated with surgical removal of the Lynch frontal approach, so present this case with a brief review of the literature.

In this paper, aspects of equalities with monomial left-hand side presented in Korean elementary school mathematics textbooks are analyzed focusing on the component of expressions. According to this analysis, the textbooks deal with equalities with monomial left-hand side as though the students already know them, rather than to introduce and deal with them systematically. In this paper, the following four suggestions based on this analysis are proposed as conclusions. First, A-type equalities (with one kinds of calculation symbols and two or more numbers, variables, denominative numbers in the right-hans side) and B-type equalities (with two or more kinds of calculation symbols and two or more numbers, variables, denominative numbers in the right-hans side) may need to be introduced by the explicit description. Second, it is necessary to establish clearly the order of dealing with numeric expressions, expressions with ${\Box}$(blank) expression, expressions with words, expressions with ${\Box}$(variable), expressions with variables. Third, it needs to be noted that equalities with monomial left-hand side cab be used with a variety of meanings. Fourth, it is necessary to widen the range of the number constituting equalities with monomial left-hand side to the natural number 0 and as well as fractions, decimals.

Background: The purpose of this study was to identify the effects of cervical manipulation for improve blood velocity and flow in the subjects with asymmetric vertebral artery. Methods: Twenty-four subjects on asymmetric vertebral artery with right side have less blood flow than left side participated in this study for apply to non-specific cervical manipulation on lower portion. Measurement method were using duplex ultrasound with colour doppler imaging for blood velocity and flow on left and right vertebral artery. Results: Compared changes of blood velocity and flow on unilateral after the cervical manipulation, the left blood velocity decreased significantly (p<.01) and the right blood velocity increased significantly (p<.01). The left blood flow no significant changes and the right blood flow increased significantly (p<.01). Compared changes of blood velocity and flow on bilateral, the left and right blood velocity and flow made significantly difference on pre-manipulation (p<.01). However, both side no significantly difference on post-manipulation. Conclusions: These findings suggest that the non-specific cervical manipulation took effect for improve blood velocity and flow in the subjects with asymmetric vertebral artery. Therefore, therapeutic approaches for improve to asymmetric vertebral artery should be consider non-specific cervical manipulation.

To demonstrate the effect of massages on the skeletal muscles of immobilization ddY mice models induced by right side sciatic nerve neurectomy, the cross sectional histological profiles of the muscularis (M) gastrocnemius, M. tibialis cranialis and M. tibialis caudalis were observed after 28 days of treatment of massages with the changes of body weight, thickness of hind limb and individual muscle weights. In addition, changes of serum aspartate amino- transferase (AST) and creatine phosphokinase (CK) levels were also demonstrated with diameter of individual muscle fiber and muscle fasciculata, and number of muscle fiber in each of three types of muscles located in the calf. The experimental groups were divided into five groups, 1) Sham-operated group (Sham), 2) Neurectomized but not massage control group (Control), 3) Neurectomized and massage at knee joint regions (T1), 4) Neurectomized and massage at calf regions (T2), and 5) Neurectomized and massages at achilles tendon regions (T3). The experimental animals were used 5 per groups. The results are as follow: 1. No significant changes of body weight were demonstrated in this groups during whole experimental periods compared to that of Sham group. In addition, no significant changes of body weight gains during experimental periods (Day 0 - Day 27: 28 days of treatment) were also observed. 2. The thickness of intact left side hind limb was not changes in all tested groups compared to that of Sham group. However, the thickness of right side hind limb were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of thickness of hind limb between right and left sides were also significantly increased in Control and massage groups (T1, T2 and T3) compared to that of Sham group. However, the thickness of right side of hind limb were significantly increased and the differences of thickness between both sides of hind limb were dramatically decreased in massage groups compared to that of Control group in followed order: T1 > T3 > T2. 3. Absolute and relative weight of M. gastrocnemius in the intact left side of hind limb was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. gastrocnemius between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were significantly increased and the differences of weight between both sides of M. gastrocnemius were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 >. 4. Absolute and relative weight of M. tibialis cranialis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis cranialis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were significantly increased and . the differences of weight between both sides of M. tibialis cranialis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 5. Absolute and relative weight of M. tibialis caudalis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis caudalis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were significantly increased and the differences of weight between both sides of M. tibialis caudalis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 6. A significant increase of serum AST levels were demonstrated in Control group. However, serum AST levels of massage groups were significantly decreased compared to that of Control group in followed order: T3 > T1 > T2. In case of 73 group, the values decreased into similar levels compared to that of Sham group. 7. A significant increase of serum CK levels were demonstrated in Control group. However, serum CK levels of massage groups were significantly decreased compared to that of Control group in followed order: T3 > T1 > T2.

We could summerize the concept of the right and left mentioned in Nai-Gyung and some literature of oriental medicine as follow At first the right and left is a directional right and left which implys left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰), secondly it is also the road of eumyang which implys man-left-woman-right(男左女右), left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse. left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰) and man-left-woman-right(男左女右) are expressions of the movement of yang which is a core of chang, at the same time, left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse are expressions of the eum in response to the movement of yang. (go up and down of water and fire) Finally, both a directional right and left and a road of eumyang mean a road of going up and down of eumyang so, this is very important index in circulation and keeping ballance of eumyang (ki-Hyul:氣血) in the human body therefore, we can treat a disease with acupuncture in the use of this charater, for example when a disease occurs in the left side, we can treat it with acupuncture in the right side, the same applys to right.

The patient was 47-year-old male who had suffered from aphasia and hemiplegia of the right side, but mental state was alert. On physical examination, BP was 130/80 mmHg in the right arm, but not checked in the left arm. The pulses of the left common carotid, brachial, and radial arteries were not palpable. The pulses of the right femoral, popliteal, and dorsalis pedis arteries were weakly palpable. Brain CT Scan revealed cerebral infarction of the left hemisphere. Aortogram showed occlusion of the left common carotid, and the right internal carotid and common iliac arteries. Subclavian steal phenomena were observed in the delayed aortogram. Double extra-anatomic bypasses; Axillo-Axillar bypass and Femora-Femoral bypass, were performed in the local anesthesia at two stages, because of risk of major operation under general anesthesia. Postoperatively, all pulses except for pulse of the left common carotid artery were equally palpable. On discharge, the hemiplegia of the right side was improved and able to walk with assistance.
