Purpose: The lateral epicondylitis is very common around elbow joint. We investigated the effectiveness of arthroscopic treatment. Materials and Methods: From Oct. 2002 to Feb. 2006, a total of 14 patients who were diagnosed with lateral epicondylitis and treated with arthroscopy were used in this study. The average symptom durations before receiving treatment was 27.3 months (9 to 47 months) and the average follow-up periods was 13.6 months (8 to 22 months). Results: The mean preoperative VAS scores was 8.3 (7 to 10 points) and the mean postoperative scores was 1.6 (0 to 4 points). The lesions of extensor carpi radialis brevis were classified using Baker's classification system. Type 1 lesion was found in 7 cases, type 2 in 4 cases, type 3 in 1 case Patients were able to return to their normal life style by 12.3 days (6 to 27 day). Conclusion: The Clinical outcomes of patients who received arthroscopic treatment were found to be good. Patients experienced lesser pain, and shorter recovery time. Therefore, when conservative treatment is ineffective in treating the lateral epicondylitis, arthroscopic treatment is considered af another option available for patients.

It seems that security police's business to secure safety of state and citizens has existed since the mankind began to create a community. State was not fully responsible for such security business from the beginning. The business was carried out autonomously by the private sector for a long period. However, as the state system had been strengthened, the public sector absorbed the function. But in the modern society where various risks exist, safety of society could not be guaranteed only by public police. Accordingly, cooperation with the private sector is indispensable. In the limit of public police, autonomous organization of security companies and general citizens is expanding its scope. As a result, they should exercise partnership as a tripod to build social safety net. Security police failed to secure manpower exclusively responsible for security, despite various businesses and excessive mobilization. Accordingly, their professionalism and ability to cope with crisis are being questioned. In particular, efficiency of security police is becoming a more urgent issue in an era of international terrorism. Private sector can be classified into security companies and private autonomous organization. In case of security companies, the problem is quality and business ability of guards compared to a rapid external growth such as quantitative expansion and advancement into various businesses. In terms of pure private activity, the necessity of understanding of public police activity and conditions for organizational and continuous activity should be prepared. To tide over such problems and effectively achieve the common goal, changes in the method of employment, new establishment of security police department, and strengthening of professionalism and crisis management ability are necessary in the public police sector. In case of security companies, improvement of relations with public police through joint education, strengthening of business ability and activation of business cooperation through these matters are necessary. To maximize activity of pure private sector, it needs to establish reserve police, manage such private autonomous organization and bolster publicity with citizens.

From 1980 to 1986,26 patients with metastatic carcinoma of the neck node from an unknown primary site were seen in the Department of Therapeutic Radiology of Seoul National University Hospital. Among these, three patients were excluded from further analysis due to incomplete treatment. So a retrospective analysis was undertaken on 23 patients who had complete treat-ment with radiation therapy alone or in combination with surgical treatment and chemotherpay. The overall three year actuarial survival rate was $32\%$. According to the staging system of the American Joint Committee on Cancer, the three year survival rates with N2 and N3 patients were $43\%\;and\;13\%$, respectively. In 16 patients with squamous cell carcinoma and seven with non-squamous cell carcinoma, the three year survival rates were $34\%\;and\;29\%$, respectively. Analysis according to site of nodal involvement was also done. Patients with cervical node and supraclavicular node involvement recorded $44\%\;and\;17\%$ of three year survival, rate, respectively. In this study, six patients eventually manifested the primary sites (three in the lung, one in the esophagus, one in the stomach, one in the nasopharynx). Presence of the primary site seemed to influence the prognosis ($17\%\;vs\;38\%$). In analyzing the prognostic factors, the nodal stage and site of nodal involvement were important prognostic factors, and the presence of a primary site seemed to influence the patients' survival, but histology did not.

Objectives : The purpose of this study is to find out the effect of Postural Yinyang Correction of TMJ(Functional Cerebrospinal Therapy; FCST) on Bell's palsy. Methods : We reviewed the medical records of 41 patients who were treated for Bell's palsy at the Dept. of Acupuncture and Moxibustion, Dong-Eui University from January $1^{st}$, 2016 to August $31^{st}$, 2016. The patients were divided into 2 groups: Group A(n=21), and Group B(n=20). Patients in Group A were treated by Korean Medical Treatments with FCST using ABA(Accurate Balancing Appliance), a standard intra-oral appliance. Patients in Group B were treated by Korean Medical Treatments without FCST. To estimate the efficacy in recovering palsy, we analyzed the House-Brackmann Grading Scale and Yanagihara's Unweighted Grading System. Results : In both groups, H-B grades were improved significantly during each period except the period from the first visit to one week later(P01). The improvement of H-B grade during each period in Group A is higher than Group B except the period from one week later to two weeks later, but statistically insignificant. In Group A, Y-score was significantly improved during each period except during P01. In group B, Y-score was significantly improved during each period except during P01 and the period from the first visit to two weeks later. The improvement of Y-score during each period in Group A is higher than Group B, but statistically insignificant. Conclusions : FCST using Standard Intraoral Appliance may be helpful in treating Bell's Palsy, but the further researches are needed.

Escape behaviour of the anchovy (Engralius japonica, total length 4-7cm) at the inside wing net and bag net in the anchovy boat seine was observed by underwater video camera in order to clarify the relationship between visual stimulus of the gear or relative water flow inside gear and reacting behaviour. The vertical attenuation coefficient of underwater illuminance in the offshore of Keoje island and Tongyoung was ranged from 0.24 to 1.03 and it could be affect visual range and visual contrast of the fishing gear. The relative water flow at the joint part between inside wing and bagnet while towing was 1.5 times higher than at the middle part of inside wing or fore part of bag net, but it was estimated under than maximum swimming speed of 4-7 cm anchovy. The mean escaping number of anchovy from end part of inside wing of 30 cm mesh to out side for a minute within visual range of video camera was 455 and anchovy swimming forward from bag net through flapper was 308. These results revealed anchovy could escape as voluntary response in spite of higher visual stimulus or higher water flow.

There is a progressive development in the medical imaging technology, especially of descriptive capability for anatomical structure of human body thanks to advancement of information technology and medical devices. But however maintenance of correct posture is essential for the medical imaging checkup on the shoulder joint requiring rotation of the upper limb due to the complexity of human body. In the cases of MRI examination, long duration and fixed posture are critical, as failure to comply with them leads to minimal possibility of reproducibility only with the efforts of the examiner and will of the patient. Thus, this study aimed to develop an auxiliary device that enables rotation of the upper limb as well as fixing it at quantitative angles for medical imaging examination capable of providing diagnostic values. An auxiliary device has been developed based on the results of precedent studies, by designing a 3D model with the CATIA software, an engineering application, and producing it with the 3D printer. The printer is Objet350 Connex from Stratasys, and acrylonitrile- butadiene-styrene(ABS) is used as the material of the device. Dimensions are $120{\times}150{\times}190mm$, with the inner diameter of the handle being 125.9 mm. The auxiliary device has 4 components including the body (outside), handle (inside), fixture terminal and the connection part. The body and handle have the gap of 2.1 mm for smooth rotation, while the 360 degree of scales have been etched on the handle so that the angle required for observation may be recorded per patient for traceability and dual examination.

Maximum mouth opening is regarded as an important tool used to evaluate the clinical function of temporomandibular joint and the masticatory system. It has been reported that children can also exhibit severe dysfunction or pain in some cases of temporomandibular disorder. The purpose of this study was to measure the normal maximum mouth opening in Korean children and to analyze the correlations between mouth opening and the associated factors. Maximum mouth opening was measured from 151 healthy children between the ages of 2 and 6 years old. Age, height, weight, and mouth width were also recorded. As a result, the mean maximum mouth-opening was $37.72{\pm}5.10mm$. While the values were greater in boys than in girls without statistical significance, the increases of maximum mouth opening based on age, height, weight, and mouth width were significant (p < 0.05). In children, positive correlation coefficients were observed between maximum mouth opening and the associated factors and height showed the highest correlation. In conclusion, we collected data of the normal range of maximum mouth opening in Korean children, and this study can be utilized as a basis in diagnosing pediatric temporomandibular disorder and safety standard of mouth opening during dental procedures.

The purpose of this study was to clarify the clinical efficiency of tungsten carbide/carbon coating on obtaining optimal preload of abutment screw compared with non-coated screw in external-hex implant system. In the present work, rotational value and the compressive force between abutment and fixture of abutment screws without coating and with coating tightened to 30Ncm were measured. Mean compressive force of coated screw was 504.6N. Then uncoated screw was tightened to clamping the abutment and the implant to 504.6N, and the tightening torque value and the rotational value was recorded. The following conclusions were drawn within the limitation of this study. Compressive force of coated screw was higher than that of uncoated screw after tightening at 30Ncm. The tightening torque that was nedeed to clamping the uncoated screw equal to coated screw tightened to 30Ncm was 55.6Ncm. In case of equal compressive force, there was no significant difference in rotation value between coated and uncoated screw.
