The objective of this research was to investigate the in vivo effects of treatment with mulberry extract complex (MEC) on cartilage degeneration and pain severity in an experimental model of rat degenerative arthritis. Monosodium iodoacetate ($2mg/50{\mu}L$) was injected into right knee joints of rats, followed by administration of MEC for 8 weeks at 400 mg/kg or 800 mg/kg of body weight. The experimental data show that treatment with MEC inhibited degradation of glycosaminoglycan and collagen in cartilage. On the other hand, concentrations of cartilage oligomeric matrix protein, C-terminal telopeptide-2, matrix metalloproteinase (MMP)-2, MMP-9, and MMP-13 in serum decreased in comparison with the control. The MEC at all dose levels could inhibit formation of xylene-induced ear edema. In this study, MEC demonstrated significant anti-arthritis activity, which is required for improvement of degenerative arthritis. Based on these results, MEC may be employed for the development of new health foods to ease symptoms of degenerative arthritis.

To compare the dietary intakes and body composition in the stage of puberty, this study was conducted with 360 girls aged 9 to 12 years in Seoul Korea. Girls's general information and 3-day diet records were collected, fat mass was measured by Inbody 3.0, bone mass at right calcaneus was measured by PIXI and pubertal development was self-assessed by picture of Tanner stages. The results are as follows: Girls who had breast development were 79.7% and 15.8% had pubic hair development. Mean of BMI, BMC and BMD were significantly higher at breast stage3+(19.6 kg/$m^2$, 1.62 kg, 0.47 g/$\textrm{cm}^2$) than at the breast stage2 (18.2 kg/$m^2$, 1.47 kg, 0.44 g/$\textrm{cm}^2$) or breast stage1(16.3 kg/$m^2$, 1.32 kg, 0.39 g/$\textrm{cm}^2$) (p < 0.001). Percent body fat of breast stage1, 2, and 3+ were 19.7%, 23.1%, 25.3% respectively and significantly increased during the puberty (p < 0.001). The mean of energy intake was 1629 kcal in stage1, 1664 kcal in stage2 and 1577 kcal in stage3+ showed significant difference in the breast stages (p < 0.05). Energy adjusted sodium intakes and crude fiber intakes were significantly higher in breast stage3 + than other breast stages. For zinc and iron, proportions of subjects with intake levels less than 75% of Korean RDA was over 40% and significantly higher in breast stage3+ than other stages (p < 0.05) ; for protein and vitamin E, the proportions of subjects with intake levels more than 125% RDA was significantly higher in the stage 1. The nutrient adequacy ratio (NAR) for protein and phosphorous was significantly lower in breast stage3+ than other stages. The food groups of seed and nut were 4.7 g/day, 2.3 g/day, 1.8 g/day, respectively, and was significantly higher in breast stage 1. In summary, mean of BMI, BMD, BMC and percent of body fat were increased with pubertal development, and those who had higher breast developmental stage showed a lower amount of consumption level in energy, seeds and nuts, and also showed a higher amount of consumption level in energy adjusted sodium and fiber among Korean girls.

Benign bronchoesophageal fistula is a rare disease and it may be characterized by nonspecific symptoms that can cause a delayed diagnosis. We misdiagnosed a patient with recurrent aspiration, which was due to bronchoesophageal fistula, as active pulmonary tuberculosis. The patient was 44 year old female who had suffered from chronic cough, especially during eating liquid meals, since 1982 when she had been treated for tuberculous lymphadenitis. Computed tomography showed an irregular mass with surrounding centrilobular nodules in the superior segment of the right lower lobe (RLL). She was diagnosed as having active pulmonary tuberculosis and treated with anti-tuberculosis medication, but she continued to complain of persistent cough even after anti-tuberculosis treatment. Thus, we reexamined the patient, and bronchoesophageal fistula between the esophagus and the superior segment of the RLL was finally confirmed by esophagography. After the fistula was surgically treated, the patient became asymptomatic and she then experienced good health.

Purpose : The purpose of this study was to compare the effects of Joing Mobilization and Group back Pain Exercise Program on the disability level and the pain of flexibility and the back muscle strength in the hearing impairment patients with Low back pain. Methods : The subjects of this study were 12 patients, 8 males and females. They visited clinic for physical treatment within 6 months after onset of low back pain. One group was applied with Joing Mobilization and other group was with Group back Pain Exercise Program. The patient were treated special program 3 times session weekly. And treatment 2 times session was 15min with physiotherapy weekly. The muscle strength was measured by Cybex 660, the level of disability by Oswestry low back pain disability scale, the intensity of pain by visual analogue scale (VAS). The data was analysed by paired T-test and independent T-test. Results : The results of this study were summarized as follow : 1. The Oswestry disability score of experimental and control group were significantly decreased and there was no difference in the Oswestry disability score change between joint mobilization group and back pain exercise group. 2. The pains in anterior, postrior, lift lateral and right lateral bending and in rotation of back pain exercise group were significantly increased compared with those of joint mobilization group. 3. The flexors and extensors peak torque of back pain exercise group were significantly increased at test velocities $30^{\circ}$/sec, $60^{\circ}$/sec compared with those of the joint mobilization group. There was no significant difference in extensors and flexors peak torque at $30^{\circ}$/sec, $60^{\circ}$/sec between two group. The results showed that the back pain exercise group were effective in decreasing disability score and pain of trunk activity, increasing trunk extension and flexion peak torque. Conclusion : It is suggested theat the back pain exercise program could be an essential factor for the effective intervension to the hearing impairment patients suffere from low back pain.
To assess the preference and efficacy of empirical fitting methods with spheric and aspheric RGP lenses. Methods: Healthy 37 subjects were fitted with spheric design (diameter 9.3 mm) on right eye and aspheric design (dia 9.6 mm) on the left eye. Base curves which were fitted empirically (using on-K, Kavg-0.50D (or 1.00D) and manufacturer's recommended fitting guide) were compared with another base curve which obtained the best diagnostic fit with spheric and aspheric RGP lenses. The preference and fitting type (lid attachment or interpalpebral) for two design lenses were investigated 2 weeks after fitting RGP lenses. Results: Of 33 successful RGP lens-wearing subjects, 76% preferred spheric design compared with 24% of aspheric RGP lens wearers. Sixty seven percent were fitted with lid-attachment in spheric lenses, whereas 64% were fitted with lid-attachment in aspheric lenses. The acceptable fit success rates within ${\pm}$0.50D of base curves were 97% for the on-K fit, 100% for the Kavg-0.50D fit and 100% of the manufacturer's guide fit compared with the diagnostic fit in spheric design, whereas 91%, 79% and 94% reported on-K, Kavg-1.00D and manufacturer's guide, respectively, in aspheric design. Conclusions: Although aspheric RGP lenses are more popular in the Korean market, it is still preferable to fit subjects with spheric RGP lenses. Empirical fitting may be best accomplished with the spheric lenses using Kavg-0.50D fit and the manufacturer's fitting guide, whereas aspheric RGP lens designs are unacceptable lens fit based on empirical fitting.
The purpose of this study is to identify the educational needs among social workers in social welfare facilities in Jeju province concerning lack of knowledge, skill and attitude, and establish the systematic education for prosecuting diverse training and suggest fundamental data for designing future curriculum. The results of analyzing top 10 educational needs for the workers are as follows: firstly technics for managing crises, understanding and practice for clients (characteristics, human right, safety and health), case management (basic), counseling technique (basic), case management (advanced), counseling technique (advanced), planning and operating social welfare program, managing client response and emotional labor, improving competence for communication (between staffs and clients, etc.), and finally assessing project outcome (project plan, execution, management and assessment, etc.). Social workers in social welfare facilities in the area have highly recognized the necessity of profession centred education. However, they had low satisfaction with the diversity of profession education in the Jeju island and the systematic training courses. This survey suggests the various results concerning qualitative growth of profession education, expansion of job-centred curriculum and security of professional instructors to fulfil systematic education training for social workers.

In this paper, with the reference of the pulse wave acquired by the pulse-checking device, it is measured the impedance on the key measuring points of the 12 kyungmaks of the human body's left and right by using 24-channels Yangdorak machine. Then, based on the Fuzzy theory, this study diagnosed the each meridian's strength and weakness. After that, both the strengthening and weakening stimulus of magnetic fields are applied to the dominant direction to find out how the degree of strength and weakness of the meridian changed. Ultimately, the magnetic therapy that can stimulate the magnetic field at the time of diagnosis and thereby balancing the interactive of five-system(O-hang) have been materialized. For the stimulation of magnetic fields, a stimulating device which can change the direction and time on a specific part of the key measuring points of the limbs of 24 kyungmaks have been developed and used. The therapeutic methods are as follows. First, the strength and weakness of the meridian have been determined. Second, both the extremely weak meridian of Yin(Shade) and Yang(Shine), and the extremely strong meridian of Yin and Yang were adjusted by applying appropriate ascending and descending stimuli respectively. All these adjusting processes can now be carried out automatically on a personal computer(PC).
The extent and direction of movement of removable partial dentures during function are influenced by the nature of the supporting structures and and the design of the prosthesis. Since forces are transmitted to the abutment teeth through occlusal rests, guide planes and direct retainers during functional movements, proper design based on the avaialble research data will maintain the health of abutment teeth and their supporting structures. The purpose of this in vitro study is evaluating stress distribution clinically around the abutment teeth prepared following 4-type clasping systems for unilateral free-end removable partial dentures. Three-Dimensional Photoelastic Stress Analysis method was used because it shows a visual display of stresses of the simulated abutment teeth and residual ridges and reveals stress concentration that can be read at any given points in terms of direction and magnitude. For this study, the author fabricated 4 mandibular photoelastic epoxy models missing left 1st and End molar. Epoxy models were duplicated and 4 unilateral removable partial dentures were construe- ted in accordance with 4-type direct retainers. Unilateral free-end removable partial dentures were positioned on their own models. 6kg force was loaded on the every removable partial dentures of the epoxy model on the central fossa of mandibular left 1st molar vertically by the loading device. After the stress was frozen in a stress freezing furnace, 6 specimens of 6-mm thickness were made from every epoxy model and examined with the circular polariscope. The results were as follows : 1. Generally I-bar clasp revealed the most favorable stress distribution around the abutment teeth. 2. At the end portion of the free-end ridge, Back action clasp showed the highest stress concentration at the bucco-lingual and top portions of the residual alveolar ridge. 3. At the distal area of the abutment teeth, Akers clasp and Roach clasp showed higher stress concentration bucco-lingually and apically than the others. 4. To the abutment tooth, I-bar clasp showed the least stress distribution bucco-lingually but the others showed irregular stress distribution. 5. At the mesial area of the abutment teeth, the order of effective stress distribution was I-bar clasp, Back-action clasp, Akers clasp and Roach clasp. There was big difference of stress distribution between them. 6. At the right 2nd premolar and 1st molar, the stress concentration of Akers clasp was a little high but that of I-bar clasp was low.
The iron status of 57 female college students was evaluated by measurements of hemoglobinCHb). hematocritCHct) and serum ferritin(Ferritin). Mean values for Hb, Hct and Ferritin were $13.9\pm$ 0.96g/dl, $41.4\pm$ 2.85% and $20.7\pm$ l5.5ng/mL respectively. Ferritin as well as Hb. Hct were not statistically different from normal distribution. although ferritin were skewed to the right. The prevalence of anemia defined by Hb < 12g/dI. Hct ~36 % and Ferritin <12ng/ml were found to be 5.3, 10.3 and 36.8%, respectively. By using Hb as a screening tool at a cutoff point of 12g/dI. 2.8% of healthy subjects will be incorrectly classified as anemic and 90.5 % of anemic as healthy. Sensitivity and specificity were calculated at various cutoff points of Hb and Hct. The estimates of sensitivity and specificity allow Hb 14.0g/dl as cutoff point for good predictor of anemia.
