Synovial chondromatosis is an uncommon disease of cartilage transformation of synovial membrane with formation of loose bodies within the joint space. The involvement of temporomandibular joint is very rare. Symtoms include swelling, pain, stiffness of the jaw, and inability to close the jaw. A case involving the temporomandibular joint(TMJ) and non-symptoms is presented.

In order to understand Changeologically on the meaning of FCST's TMJ (temporo-mandibular joint) treatment procedure, Yi, Shike, Bi, Gen trigrams concerning the jaw and change by treatment were analyzed from the viewpoint of semiotic context of hexagon and holistic interpretation on disease. Yi is meant by jaw but actually indicates mouth made by maxilla and mandible, and it's characters are related with nourishing by aliment and words. But when we eat and speak in the daily life, jaw does not nourish properly it's own body by bad habit or postures. For the treatment of this ill state, there needs punishment and correction symbolized with Shike. Shike has fourth nine meaning obstacles between the two strong lines in the upper and lower end, and so it has the function of mastication and get rid of the fourth nine metaphorically indicating subluxation of axis using CBA and auxiliary measures of four movement or laughing methods. Bi expresses the achievement and effects of consecutive mastication process implicating normalized manifestation of jaw and its linked spinal function. Gen symbolizes removing selfish motive or partiality in advance and reaches the best state of the saint righteously self-nourishable human being.

In this study, we aim to describe kinematic characteristics of Korean /l/-flapping in two speech rates (fast vs. comfortable). Production data was collected from seven native speakers of Seoul Korean (four females and three males) using electromagnetic midsagittal articulometry (EMMA), which provided two dimensional data on the x-y plane. We examined kinematic properties of the vertical/horizontal tongue tip gesture, the vertical/horizontal (rear) tongue body gesture, and the jaw gesture in an /i/-/i/ context. Gestural landmarks of the vertical tongue tip gesture are directly measured. This serves as the actual anchoring time points to which relevant measures of other trajectories referred. The study focuses on velocity profiles, closing/opening spatiotemporal properties, constriction duration, and constriction minima were analyzed. The results are summarized as follows. First, gradiently distributed spatiotemporal values of the vertical tongue tip gesture were on a continuum. This shows more of a reduction in fast speech rate, but no single instance of categorical reduction (deletion). Second, Korean /l/-flapping predominantly exhibited a backward sliding tongue tip movement, in 83% of production, which is apparently distinguished from forward sliding movement in English. Lastly, there was an indication of vocalic reduction in fast rate, truncating spatial displacement of the jaw and the tongue body, although we did not observe positional variations with speech rate. The present study shows that Korean /l/-flapping is characterized by mixed articulatory properties with respect to flapping sounds of other languages such as English and Xiangxiang Chinese. Korean /l/ flapping demonstrates a language-universal property, such as the gradient nature of its flapping sounds that is compatible with other languages. On the other hand, Korean /l/-flapping also shows a language-particular property, particularly distinguished from English, in that a backward gliding movement occurs during the tongue tip closing movement. Although, there was no vocalic reduction in V2 observed in terms of jaw and tongue body height, spatial displacement of these articulators still suggests truncation in fast speech rate.

Three species, Gymnogobius urotaenia, G. sp. 1 and G. sp. 2, collected at Hosan-river, Hosan-ri, Samcheock-si, Gangwon-do, Korea, were examined for the study of sexual dimorphism. The three species have peculiar nuptial pigmentation during the breeding season: all females of the three species showed an intense black coloration on the ventral part of the head, the pelvic fin, the anal fin and the margin of the first dorsal fin. There was a difference between G. sp. 1 and the other two species in 1/3 from margin of first dorsal fin. Namely, G. sp. 1 showed an intense black coloration, whereas the other two species had an intense yellow coloration. All females of the three species showed the same, intensely yellow coloration in the ventral part of the body. Males of G. urotaenia and G. sp. 2 had almost the same nuptial pigmentation, however the former showed diffuse black coloration in the anal fin, whereas the latter had an intensely black anal fin. Males of G. sp. 1 differed from those of the other two species in their yellow color on the ventral part of the head, the pelvic f ins, the anal fin, in contrast to the diffuse black coloration in those parts in the other species. The genital papilla of males was triangle-shaped, but that of females was heart-shaped. Significant differences between sexes include: G. urotaenia, 7 characters (body depth, head length, snout length, upper jaw length, head depth, pectoral fin ray length, eye diameter); G. sp. 1, 11 characters (body depth, head length, caudal peduncle length, caudal peduncle depth, snout length, upper jaw length, head width, head depth, anal fin ray length, pectoral fin ray length and caudal fin ray length); G. sp. 2, 10 characters (body depth, head length, caudal peduncle depth, snout length, upper jaw length, head width, anal fin ray length, pectoral f in ray length, caudal fin ray length and eye diameter). Of the 5 characters which showed differences in all three species (body depth, head length, snout length, upper jaw length and pectoral fin ray length), females had higher values than males only in body depth, whereas males values in all other characters. The upper jaw length was the most distinctive sexually dimorphic feature, the upper jaw extended beyond the posterior margin of the eyes (p<0.001) in males but not in females.

Intraosseous carcinoma of the jaw may arise as metastatic lesions most commonly from breast, lung, kindney and thyroid and also primarily occur from ameloblastoma or odontogenic cyst. Rarely primary intraosseous carcinoma could be originated from the epithelium involved in odontogenesis. According to WHO's classification, primary intraosseous carcinoma is defined as squamous cell carcinoma, occured in the Jaw without connection to the oral mucosa. However, Elzay defined primary intraosseous carcinoma as malignant epithelial tumor related to the odontogenic apparatus, including carcinoma ex-odontogenic cyst, carcinoma ex-ameloblastoma and carcinoma de novo. We experienced 2 cases of intraosseous carcinoma of the jaw. The first case, a 59-year-old man, showed a ill-defined mass on the left maxilla, measuring $8{\times}10cm$ in size. He received radical hemimaxillectomy and was diagnosed as ameloblastic carcinoma. The second case obtained from a 79-year-old woman showed a ill-defined $6{\times}8cm$ sized mass on the left mandibular body area. The mass was surgically removed by partial mandibulaectomy, which was diagnosed as the primary intraosseous carcinoma, probably odontogenic origin.

Background and Objectives : The common cause of voice disorders may be bad habits of phonation. faulty vocal habits might aggravate the voice disorder or make the dysphonia. Authors thought the analysis of faulty vocal habits might help to evaluate the causes and to choose the treatment methods in patients with dysphonia. Authors studied to evaluate which vocal habits were used in patients with dysphonia. Materials and Methods : Patients with dysphonia(N= 32) and person without dysphonia(N=20) were evaluated through pre-evaluation test by otolaryngologist and SLP. All subjects were evaluated accordingly Posture of body, expansion of cervical vein, excessive movements of thyroide prominence, position of tongue, tension of lower lip, tension of jaw, breathing pattern related with phonation. Results : In dysphonia group, we found 23 cases with tension of jaw, 15 cases with expansion of cervical vein, 7 cases with bad position of tongue, 3 cases with excessive movement of thyroid prominence and a lot of cases with bad breathing Pattern on Phonation. In control group, only 3 cases with bad position of tongue, 2 cases with tension of lower lip, 1 case with tension of jaw were found. Conclusions : More faulty vocal habits were found in dysphonia group. Authors thought faulty vocal habits could be the cause of dysphonia and aggravate the dysphonia and the control of vocal habits would be very important in patients with dysphonia.

The authors had observed a case of cleidocranial dysostosis of 42 years old unmarried woman. The observation was founded upon roentgenogram of skull P-A view, orthopantomograph, cephalometric view, chest P-A view and wrist X-ray view. The patient gave a dwarfic impression with 145㎝ body height and concaved mandibular prognastic facial feature. The palate was narrowed and extremely high arched. The eruption state of teeth were extremely poor, only four teeth were erupted, composed of upper third molar and lower three deformed teeth. The skull P-A view of roentgenogram reveals overlying metopic suture, extends from the nasion to the sagittal suture, and the suture are delayed up to date and many wormian bones are formed. On the cephalometric view the maxilla is underdeveloped and produce the false mandibular prognathism. Twenty four impacted teeth can be detected by orthopantmograph, twelve in upper jaw and twelve in lower jaw. There are many supernumerary teeth, one in upper jaw and seven in lower jaw. On the chest P-A view, the clavicles are totally aplastic, but a vestige of clavicle is visible in the right side. On the wrist roentgenogram, the epiphyseal ossification of distal phalanx, mesial phalanx and proximal phalanx is delayed.

Purpose : The goal of this study was to compare and analysis the dose distribution and treatment time between Tomotherapy planning with fixed jaw(FJ) and dynamic jaw(DJ). Materials and Methods : Seven patients were selected in the study including five common clinical cases(brain, head and neck(HN), lung, prostate, spine). 1) Helical Tomotherapy plans with FJ and DJ were generated with the same planning parameters such as Modulation factor, Pitch and Field width. 2) Tomo_edge plans with a larger field width were generated to compare to conventional HT delivery with fixed jaw. Dosimetric evaluation indices for target coverage are Dmin, Conformity index(CI) and for whole body including target are $V_{10%}$, $V_{25%}$, $V_{50%}$, $V_{75%}$ using Dose-volume histogram(DVH). Also, Treatment time and Cumulative MU were used for clinical review on Tomo_edge. Results : In case of using the same field width of Tomotherapy planning with FJ and DJ, the averaged variations were $V_{10%}$: -11.91%, $V_{25%}$: -7.6%, $V_{50%}$ :-4.75%, $V_{75%}$: -1.04%. Tomo_edge with a larger field width provides the averaged variations for target coverage: Dmin: -0.72%, CI: -1.25% and also shows the tendency of a sharp $V_{x%}$ decline in low dose area. The clinical improvements in the larger field width with DJ were observed in the treatment time, ranging from -51.21% to -15.11, and the Cumulative MU decrease, ranging from -57.74% to -15.31%. Conclusion : Target coverage achieved by FJ and DJ with the same field width has little differences. But integral doses on whole body efficiently decreased. Compared to the conventional HT delivery, Tomo_edge with a larger field width presents a little worse target coverage. However, it provides faster treatment delivery and improved cranial-caudal target dose conformity. Therefore, Tomo_edge mode is efficient in improving the treatment time and integral dose while maintaining comparable plan quality in clinic.

Objectives : The Jap Byoung(雜病) of the Young Chu(靈樞), one of the classical book of oriental medicine contains symptoms and remedies for various diseases that can be seen on human body. But it is too difficult to understand the Jap Byoung(雜病), because it is written in old chinese and there are many printer's error and omissions or adds in this book. As a consequence of above reason, the writer of this article has researched to find out the exact meaning of that. Methods : So in this part we study a woodblock-printed book of successive generation and view of annotators, and add adding notes, adjustment, translation to exact comprehension of the original text. Results & conclusions : The principle ideas of the thesis can be summarized as follows: The Jap Byoung(雜病) is consist of five part. In chapter 1, we present symptoms occurred by the upstream current of Qi(氣逆) and their treatments by taking meridian flowing the body parts on which the symptoms occur. In chapter 2, we deal with symptoms such as ikgun(?乾), a pain of the knee(膝中痛), huby(喉痺), epistaxis(?血), lumbago(腰痛), anger(怒), a pain of the jaw(痛), a pain of the nape(項痛) and their remedies. In chapter 3, since abdominal inflation occurs when the Qi(氣) of the five viscera(五臟) is damaged or go upstream, I discussed that the treatment should be given by taking the meridian accordingly. In chapter 4, we deal with the remedy for heartache, and different meridians to be taken by symptom, and parts on which needle to be used, and detailed remedies. In chapter 5, we present other diseases, detailed body parts to be cured and remedies by referring symptoms for a pain of the jaw(痛), the upstream current of Qi(氣逆), hiccup, etc. Especially, we introduce a part of Doinbup(導引法) for wegurl(?厥) and remedies for hiccup such as inducing sneeze by stimulating nostrils, holding one's breath, etc.
