The purpose of this study is about the installation process and managing system of Economic Development District installed in order to make economic and local development by introducing foreign investment, technology and managing methods after the reformation of China. The Economic Development District of China is being continuously enlarged in its quantity and form as the local opening is being enlarged, and so that it is leading the systematic change of open district and is being developed as a core part of local economic growth. The central and local governments used to mediate and control the fostering of Economic Development Districts in their initial stage. However, the economic and business activities in Economic Development Districts are controlled by the capitalistic market forces now, and the control of central and local governments are being reduced to the minimum and the autonomy of the administrative commission is being reinforced for the efficiency of Economic Development District.

Objectives: The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. Materials and Methods: Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (${\geq}35mm$) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. Results: With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. Conclusion: Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

Researches on prodigies and education for those have recently been progressing in many fields. Education for the gifted, which was basically on Math and Science on the start, now includes Intelligence, Invention, Cultural Sciences, Art, and so on. With the progression towards extremely developed information society, interests in and importance on the courses for the talented get more and more focused. The problem is, however, choosing the gifted and educating them is not an easy matter, since the history of Intelligence Technology is relatively short and it is hard to identify prodigies and categorize what kinds of courses they need. Also, from 2010 "Science Education Institute for the Gifted" freshmen draft, paper-based admission test has been discarded and teacher-recommendation through long-term observation introduced. Therefore needs have been increasing for quality selection methods including observation records, recommendation letters, and portfolios. Reformation on teaching and creative selection methods has been accentuated because of lack of academic base for selecting candidates for education for the gifted. Because of all those mentioned above, reliances for the selection processes during the last three years and the one in 2010, observation records, recommendations and portfolios included, have been analyzed and evaluated. Several factors which can be used instead of paper-based tests were coordinated. Based on it, it was highly possible and has been successful to draft all the applicants in cognitive, sentimental, and creative fields.

The use of Hydrogen as a fuel is receiving considerable attention and as a result, research on novel methods of hydrogen production is necessary so that the hydrogen demands in the future can be satisfied. This study presents experimental data on methanol Autothermal Reformation that quantifies the relationship between the oxygen-to-methanol ratio ($O_2/CH_3OH$) and reformer efficiency. For each catalyst configuration, the $O_2/CH_3OH$ was varied from 0.1 to 0.4, with an increment of 0.05, to investigate the effects of $O_2/CH_3OH$ on the reactor performance, including temperature profile, conversion, and efficiency. $O_2/CH_3OH$ was increased from 0.15 to 0.20, and the catalyst bed temperature increased by $235^{\circ}C$ to approximately $550^{\circ}C$. The catalyst bed temperature increased with increasing $O_2/CH_3OH$ as the reaction shifted from endothermic to exothermic reaction and as a result, excess heat, which raised the reactor temperature, was generated. The reactor performance was shown to be highly dependent on $O_2/CH_3OH$. The optimum $O_2/CH_3OH$ = 0.30 found in the experimental tests is 30% higher than the theoretical optimum of 0.23. This is attributed to a combination of factors such as the concentrations of the $O_2$ and $CH_3OH$ gas, reaction rate, catalyst effects, heat loss from the reactor, and the difference between the actual amounts of reaction products formed and the theoretical amounts of the reaction products.
The present study was performed to identify the relationship between plasminogen activator (PA) and Heat Shock Protein-90 (HSP-90) in porcine uterus tissues during the estrous cycle. Porcine uterus tissues were obtained from preovulatory (Pre-Ov), post-ovulatory (Post-Ov) and early to mid-luteal (Early-mid L) stages. The protein was extracted from uterus tissue by using M-PER Mammalian Protein Extraction Reagent. Proteins were refined by RIPA Buffer and quantified by BCA methods. As results, t-PA expression was significantly (p<0.05) higher from pre-ovulatory(Epithelium tissue: $29,067{\mu}g/{\mu}l$, Myometrium tissue: $30,797{\mu}g/{\mu}l$) compared to the post-ovulatory stage(Epithelium tissue: $54,357{\mu}g/{\mu}l$, Myometrium tissue: $53,270{\mu}g/{\mu}l$) and early to mid-luteal stage(Epithelium tissue: $42,380{\mu}g/{\mu}l$, Myometrium tissue: $43,139{\mu}g/{\mu}l$). On the other hand, the uPA expression indicated higher from early to mid-luteal stage (Epithelium tissue: $0.02198{\mu}g/{\mu}l$, Myometrium tissue: $0.02412{\mu}g/{\mu}l$) than pre-ovulatory stage (Epithelium tissue: $0.01577{\mu}g/{\mu}l$, Myometrium tissue: $0.01531{\mu}g/{\mu}l$) and post-ovulatory stage(Epithelium tissue: $0.01414{\mu}g/{\mu}l$, Myometrium tissue: $0.01429{\mu}g/{\mu}l$). However, expression of u-PA did not differ from each estrous cycle in the epithelium tissue and myometrium tissue(p<0.05). Expression of HSP-90 was differ t-PA and u-PA from pre-ovulatory in Epithelium tissue($25,423{\mu}g/{\mu}l$) and early to mid-luteal stage in epithelium tissue($177,922{\mu}g/{\mu}l$) and myometrium tissue($26,664{\mu}g/{\mu}l$). These results suggest that HSP-90 and u-PA were related with change of uterus cycle according to the reformation of the tissues in porcine uterus.
When customer makes a phone call to get the necessary information, ARS (Automatic Response System) will provide them without the limitation of time and place. Therefore, the application field of ARS (Automatic Response System) has been expanded and also occupancy rates arepretty high. However, compared with the importance of ARS, there is little study regarding the closest information structure of the actual users. Therefore, this research is about the ARS information structure of Gimhea BIS (Bus Information System), and the point of this research is to analyze the problem of the ARS information structure so we can suggest an idea to improve it. As the methods of study, drawing the workflow of ARS, conducting user observation, comparing with cases another region and analysis them. As a result, by and large there was error in the structure of information so, system reformation was required. Now that, we suggested two ideas for the improvement and we conducted usability test under that problem. Usability test was conducted by Lab test with interview. As a result, we could understand merits and demerits of two ideas for improvement, and we completed final improvement to highlight only merits of two ideas for improvement. This study will be utilized as the base material to improve ARS of Gimhea BIS.

This study is conducted to compare how the Western.Oriental medical practitioners and health professionals perceive reciprocal development strategies respectively of Western.Oriental Medicine in Korea. A total of 3,273 persons were questioned by direct distribution, e-mail, and mail with a self-developed questionnaire. Of those questioned, 362 responded (the response rate of 11.1%), and of them n persons (Western medical practitioners 206, Oriental medical practitioners 90, and health professionals 64) were analyzed with SPSS for Windows. The results were as follows: The need for legislation on the mutual development system for Western.Oriental Medicine was recognized by 66.9% (218 persons) of respondents. Among them, largest group who agreed with this need was the health professionals. Western medical practitioners chose the "the difference of approach methods on the diseases between Western.Oriental Medicine" as their response, and Oriental medical practitioners & health professionals selected "the indifference or bias of Western medical practitioners"as the reasons for the inactivity in developing a mutual system of Western.Oriental Medicine. Therefore, Western medical practitioners and health professionals selected the category of "the reformation of educational system", while Oriental medical practitioners selected the category of "the activation of joint research on Western.Oriental medical care" as the most important condition for setting a precedent. Also, Western medical practitioners preferred "cooperative health care system for Western medical care supported by Oriental medical care", but Oriental medical practitioners and health professionals preferred “cooperative health care system of Western.Oriental medicine on equal terms" In conclusion, Western '||'&'||' Oriental medical practitioners have to make every effort to close the gap between differing views through mutual understanding and respect if joint research of Western.Oriental medical care is to become a reality. The government should continuously enforce the health policy on development of a legal and systematic infrastructure for mutual development strategy of Western.Oriental Medicine in Korea.strategy of Western.Oriental Medicine in Korea.
Objective: The purposes of this study were to provide an epidemiologic data base related to the orthodontic treatment need and to know the changing trends about treatment modality of private orthodontic clinics. Methods: Distribution, trends and orthodontic treatment plan of malocclusion patients were investigated in 1,620 consecutive patients who had been visited and examined in 4 private orthodontic clinics located in Seoul from 2003-2006. Results: Percentage of male and female patients was 26.9% and 73.1% respectively Age distribution had shown that percentage of the patients above 13 years was 78.9%, and above 19 years was 59.0%. Average age of whole patients was 20.5 years. With regard to Angle classification, each percentage of Class I, Class II division 1, Class II division 2 and Class III malocclusion was 38.9%, 34.8%, 2.3% and 24.0%. The percentage of extraction cases(00.9%) outnumbered nonextraction cases(39.1%) and 46% of extraction cases were upper and lower 1st premolar extraction cases. Patients who had chose treatment with fixed appliance and orthognathic surgery was 10.2%. Conclusions: Because the high percentage of adult, Class II malocclusion and orthognathic surgery cases in patients of private orthodontic clinics were shown in this study, orthodontic education program and national health policy in Korea need reformation.
Purpose: The purpose of this study was to evaluate the clinical results of anatomic reduction of bony mallet finger using modified-intrafocal pinning technique. Methods: From March 2014 to October 2017, 18 patients with bony mallet finger were treated with modified-intrafocal pinning technique. Kirschner-wire was used to directly reduction the bony fragment, and extension block pinning and distal interphalangeal joint fixation were additionally performed to minimize the loss of reduction. Postoperative pain, range of motion, and radiological evaluation were performed. Duration of bone healing, functional recovery and complication rate were evaluated and Crawford's criteria was used to determine functional outcome after surgery. Results: Bone union was achieved in all cases after a postoperative mean of 6 weeks (5-7 weeks). An average of $2.8^{\circ}$ ($0^{\circ}-10^{\circ}$) extension loss occurred in all patients. All patients showed satisfactory joint congruency and reformation of the joint surface, the mean flexion angle of the distal interphalangeal joint at the final follow-up was $72.2^{\circ}$ ($70^{\circ}-75^{\circ}$). According to Crawford's classification, 12 patients (66.7%) were excellent and 6 patients (33.3%) were good. Conclusion: Modified-intrafocal pinning technique is a method of obtaining anatomical bone healing by directly reduction and fixation of the bony fragment. Combined with other conventional percutaneous pinning procedures, it is expected that good results can be obtained if applied to appropriate indications.
