The present study was performed to establish the cephalometric standards of Hellman dental age II C groups of Korean on the roentgenocephalometry. The subjects consisted of 26 males and 25 females with normal occlusion and acceptable profile. The major conclusions may be listed as follows: 1) The tables of standard deviation from the measurements were made. 2) All linear measurements of skeletal pattern in male were greater than in female with exception of the mandibular body length measurement. 3) The labial inclinations of the upper and lower incisors were greater in female than in male. 4) Vertical growth tendency of the face nab conformed in the late primary dentition as compared with the measurements of the mixed dentition.

Polymorphic reticulosis is characterized by relentlessly progressive, localized, destructive inflammation process that predominently involves upper respiratory tract, nose, paranasal sinuses, nasopharynx and face. It is a rare and fetal disease in otolarynogologic field. Recently the authors carried out clinical observation on the two cases of polymorphic reticulosis diagnosed histopathologically after biopsy and treated by only radiation therapy with good result.

A properly determined separation minima applied in Air Traffic Management(ATM) is critical for safe and efficient aircraft operations. The separation minima is primarily determined by the accuracy performance of surveillance system, and, due to the stringent aviation safety standard, the position accuracy of the surveillance system must be estimated with a high level of reliability. This study proposed a method for estimating the position accuracy of surveillance system with a relatively small amount of data by finding upper confidence limit instead of maximum likelihood values of unknown parameters. Through the proposed method, it is possible to determine a required separation minima with a more reliability in the face of data scarcity which often occurs when we implement a new surveillance system such as Automatic Dependent Surveillance-Broadcast (ADS-B).

Melasma is a common disorder that causes dark colored patches. It generally causes brown spots on the face, especially on the forehead, cheeks, and upper lips. The pattern of patches has bilateral symmetry in yellowish-brown to gray-brown colors. It is much more common in women than in men. Melasma is considered to be caused by environmental and physical constitutional factors and often occurs when a woman's hormone changes by pregnancy or the use of oral contraceptive pills. It is important to combine oriental medicine and Sasang constitutional medicine for treatment of Melasma. Normal treatment of Melasma includes warming oneself, removal of the emotional stress factors, and good nutrition.

Genioplasty may considerably change a person's face which needs surgical correction of deformed chin. Comprehensive treatment planning is therefore decisive for the treatment to be successful. A three-dimensional analysis of chin relative to cranial base, upper and lower jaws using the frontal and lateral facial photographs and cephalographs permits classification of the defective chin position and provides a basis for operation planning and deciding upon the operation method. A chin miniplate system has been developed for intraoperative registration securing the sagittal, vertical and horizontal position of the osteotomized chin and ould reduce the relapse rate.

Herpes zoster oticus which is called Ramsay Hunt syndrome, geniculate ganglion herpes and otic herpes, is characterized by a viral prodrome with otalgia, vesicular eruptions, facial paralysis, hearing disturbance, tinnitus, vertigo and other symtoms. Among cranial nerves, trigeminal and facial nerves are the most commonly affected in patients with herpes zoster oticus, but on rare occasions 8th, 9th, 10th, 11th, 12th cranial nerves and even the upper cervical nerve are influenced as well.. In general, it has poor prognosis compared with Bell's palsy, leaving permanent facial nerve dysfunction. We report a case of Herpes zoster oticus, which was fully recovered by acupuncture and herbal medication within 12 days. We used $FEMA^{11)}$ and House-Brackmann's grading system to assess the degree of paralysis in each part of face.

Myoclonus is manifested in a variety of situations including metabolic derangements, brain lesions, epilepsy, and drugs toxicity. We reported a rare case of amitriptyline-induced myoclonus. A 64-year-old man with a tension-type headache was administered amitriptyline at 15 mg/day. Eight days after initiation of amitriptyline, multifocal myoclonus developed, involving the face and upper extremities. Two hours after the administration of clonazepam at 1 mg, myoclonus resolved completely.

The study was performed to investigate cephalomeric similarity between parents and offspring of the Korean family by lateral cephalometric analysis. The lateral cephalograms consist of the 8 families comprising 16 parents, 5 sons and 7 daughters. In order to make an investigation of the similarity, set up, and 22 linear measurements on each depth measurements were made. The author drew up the profilograms to compare parents with offspring in each family group. The obtained results were as follows: 12 measuring points were and height and 5 angular 1. There was no common similarity on specific region between parents and offspring on each family group. 2. There was partial similarity between single parent and offspring. 3. The partial similarity between single parent and offspring was noted on the upper face in general.

In this paper, multi-objective models for designing 3D trajectory of horizontal wells are developed in a fuzzy environment. Here, the objectives of minimizing the length of the trajectory and the error of entry target point are fuzzy in nature. Some parameters, such as initial value, end value, lower bound and upper bound of the curvature radius, tool-face angle and the arc length of each curve section, are also assumed to be vague and imprecise. The impreciseness in the above objectives have been expressed by fuzzy linear membership functions and that in the above parameters by triangular fuzzy numbers. Models have been solved by the fuzzy non-linear programming method based on Zimmermann [1] and Lee and Li [2]. Models are applied to practical design of the horizontal wells. Numerical results illustrate the accuracy and efficiency of the fuzzy models.
