Osteoarthritis (OA), the most common form of arthritis, is a result of both mechanical and biological events that destabilize the normal coupling of degradation and synthesis of articular cartilage chondrocytes and extracelluar matrix, and subchondral bone. Although it is likely that the molecular basis of pathogenesis is similar to that of other joints, additional study of the temporomandibular joint (TMJ) is required due to its unique structure and function. This study was carried out to evaluate the epidemiologic characteristics of TMJ osteoarthritis. The purpose of this study was to investigate the prevalence of TMJ OA in Patients with temporomandibular disorders (1405 men and 2922 women whose mean age was $30.2\; {\pm}\; 15.4$ and $33.1\;{\pm}\;15.2$ years, respectively) who had visited the TMJ and Orofacial Pain Clinic of Seoul National University Dental Hospital in 2007. Orthopantomograms, TMJ tomograms and transcranial radiographs were used to evaluate degenerative change of the mandibular condyle. The obtained results were as follows: 1. Degenerative change of the mandibular condyle was observed in 883 (20.4%) of 4327 subjects. The prevalence was significantly higher in women (706 patients, 24.1%) than in men (177 patients, 12.6%), and this significant difference between genders was observed in all age groups. 2. The prevalence of degenerative change of the mandibular condyle in TMD patients showed a gentle increase along with age. Such increase was statistically significant in women (P < 0.001), but not in men. 3. Sclerosis was observed the most frequently in all age groups and the mean age of the patients with osteophyte was the highest among four types of degenerative change. 4. Although men showed degenerative change in the left side more often and women showed degenerative change more frequently in both sides, the difference of distribution in sides between genders was not significant. In conclusion, the prevalence of degenerative change of the mandibular condyle in TMD patients is higher in women than in men, and increases steadily with aging, but not as dramatically as in other joints that show a steep increase in prevalence around the age of 45 years. It can be suggested that the epidemiologic characteristic of OA of the TMJ differs from those of other joints, and that a more extensive study based on the general population is necessary.

Oral appliances therapy is becoming increasingly recognized as a successful treatment for snoring and obstructive sleep apnea(OSA). Compared with continuous positive airway pressure(CPAP), the gold standard therapy for OSA, oral appliance therapy are less efficacious for severe OSA but are more acceptable and tolerable for patients, which in turn, may lead to a comparable level of therapeutic effectiveness. Nevertheless, the various side effects of oral appliance therapy, such as, increased salivation or dryness, pain or discomfort in the teeth or gums, occlusal discomfort in the morning, temporomandibular disorders, dental and occlusal changes may cause discontinuation of treatment or changes in treatment plan. Therefore, oral appliance therapy should be provided by a qualified dentist who can evaluate oral tissues, occlusion, and temporomandibular joints, and prevent and manage the possible side effects.

염건 숭어알을 10% 염농도의 간장에 침지하고 1.2㎝ 두께로 압착하여 20℃에서 3m/seC 풍속으로 음건하여 제조하였다. 제품의 지질을 중성지질, 당지질 및 인지질로 분획하고 유리인지질은 9.3㎎/100㎎, 결합인지질은 13.0㎎/100㎎함유하였으며 가공과 저장중에 빠른 속도로 감소하였다. 인지질을 구성하는 주요 지방산은 C_(16:0), C_(20:0), C_(16:1), C_(18:2)와 C_(20:5)였으며, 이들 지방산의 함량은 6.64㎎/100㎎으로 총인지질 지방산의 72%를 점유했다. 불포화도는 유리 인지질에서 1.53이었고 결합 인지질에서는 0.34로 낮았다. 그러나 결합 인지질의 불포화도는 신선할 때는 1.04이었고 6주후에는 0에 가깝고, 필수지방산도 3.85㎎/100㎎으로 전체 필수지방산의 75% 정도이었으나 가공중에 거의 파괴되었다. Mullet roe was salted and dried by the conventional processing method. Mullet roe was first salted with soybean sauce containing 10% NaCl and then pressed down to be a 1.2㎝ of thickness. It was dried at 20℃ under 3m/sec of aeration for 20 days. The lipids of the processed roe were fractionated by free and bound phospholipids. The contents of free and bound phospholipids were 9.30㎎/100㎎ and 13.0㎎/100㎎ respectively. The content of bound lipids were rapidly decreased than that of free fatty acids during processing and storaging. The major fatty acids of phospholipids were C_(16:0), C_(20:0), C_(16:1), C_(18:2) and C_(20:5), whose contents were 6.64㎎/100㎎ that occupied 72% of the total phospholipids. The ratio for the unsaturated fatty acids to the saturated ones of free phospholipids in fresh roe was 1.53 and it was decreased down to 0.34 in 9 weeks of storage. But the ratio of bound phospholipids was 1.04 of fresh roe and zero in 6 weeks. The content of essential fatty acids in bound phospholipids was 3.85㎎/100㎎ occupying 75% of total essential fatty acids of the fresh roe, but they were totally destroyed during processing.

The purpose of this study was yo investigate the effect of prior exercise resistance and rest perriod on Harvard Step Test. Male subjects(n=10) aged 19-23 performed prior exercise consisting of sit-ups(2min) and 1,000m run. After the prior exercise, the subjects rested for 3min, 5min,10min before staring Harvard Step Test. It was hypothesized that subjects demonstrate different performances in prior exercise, rest period on Harvard Step Test. The study design was a 2-way (prior exercise ×rest period) factorial ANOVA with repeated measures on assigned factors. The levels of assigned factors were: Prior exercise resistance and rest Period. The dependent variables was Harvard Step Test index. Statistical significant differences at the 0.5 level were found between the overall mean of the resistance level of two prior exercise, but were found between the overall means of the three rest period level. A significant interaction among prior exercise resistance level and rest period level was not found. It was concluded that the releabilitv the Harvard Step Test as physical fitness test is assured if subjects take at least 3min rest period after prior exercise of sit-ups and 1.000m run. It is necessary to standerdize the testing procedures of prior exercise in a great detail when administring Harvard Step Test.

This study was attempted to investigate the physical fitness and psychological variable structures of athletic events with the weight classes. The 9 physical fitness test as discriminators, such as grip strength, back muscle strength, forward trunk flexion, backward trunk flexion, Harvard-step test, 2000m run, vertical jump, 50m run, side step test were used. And I psychological variable test were used such as “Psychological Assesment Index.” The subjects included 225 male athletes sampled from wrestling, boxing, judo, taekwondo and weight lifting athletes of KNCPE The SPSS computer program were used for data analysis. Multiple statistical treatments such as univariate analysis of variance, principal axes solution, and Wilk's Lambda test were applied for analyzing discriminant functions of 9 physical fitness test. The results of initial univariate analysis of variance showed that in the athletic events with weight classes group have sufficient power for discriminating the selected athletic events with weight classes group at .05 level. Further stepwise methods were employed to determine the best discriminators. The identified to the athletic events with weight classes separation were as follows: (1) grip strength (2) back muscle strength (3) backward trunk flexion (4) Harvard step test (5) 2000m run (6)vertical jump (7) side step for athletic events with weight classes. The discriminant functions for physical fitness which can be adopted to classify the elite athletes into athletic events with weight classes are cardiovascular endurance, flexibility. But the psychological variable was not shown significantly difference between athletic events with weight classes.
