국내 시판중인 ciprofloxacin 제제인 Citopcin®(250㎎ tablet)의 동등성을 검토하기 위해 제조원인 Bayer사의 Citopcin®(250㎎ tablet)를 기준제제로 하여 18명의 건강한 남성 피험자를 대상으로 500㎎ 1회 교차 경구 투여후 약동학적 성상을 분석비교한 결과는 다음과 같다. 시험제제의 생체 이용율의 지표인 AUC, C_(mao), T_(max) 및 MRT들의 평균치는 백분율차이에 있어 모든 기준제제 지표의 ± 20% 이내였으며, 이들 생체 이용율 지표들은 분산분석 검정에서 차이를 인지할 수 없었다.생체 이용율 지표들의 기준제제에 대한 백분율 90% 대칭 신뢰구간 검토시 모든 경수들에서 ± 20% 이내의 조건을 만족하였으며 AUC의 경우에는 대칭형 신뢰구간으로 변환시 95% 신뢰구간에서도 동등성의 조건을 만족하였다, 이상의 시험결과로 시험제제인 Citopcin®은 기준제제인 Ciprobay®와 생물학적 동등한 제제로 판단되었다. The pharmacokinetics of ciprofloxacin was studied for the evaluation of the bioequivalence of the generic ciproflocacin products. Two single doses of 500㎎ each of ciprofloxacin(Ciprobay® 250㎎ tablet as a reference compound and Citopcin® 250㎎ tablet s a test compound) were administered orally to ighteen male volunteers in a balanced, randomized crossover design. Pek plasma levels of ciprofloxacin were observed about 1 hour after the doses and the peak concentrations of both products were similar(Ciprobay®, 3.18㎍/㎖; Citopcin®, 2.89㎍/㎖). The values of other pharmacokinetic parameter of ciprofloxacin computed for Ciprobay® are presented in that order: AUC=13.53:12.47㎍·h/㎖, T_(max)=1.28:1.14 hours; MRT=5.30:5.08 hours; t_(1/2)β=3.65:3.47 hours. No satistically significant, differences were detected when AUC and the other parameters were compared with the method of ANOVA. Using the criteria of 90% confidence interval for the assessment of bioequivalence al the parameters were acceptable. The products were found to be equivalent on the premise that no significant difference was detected when the relevant pharmacokinetic parameters were compared, and the confidence limit analysis showed acceptable results.

The Internet of Things, the core of the Fourth Industrial Revolution, is growing by applying various technologies to various fields. Among them, smart home systems that apply IoT technology to home environments are actively being researched, and the home hub market, which is a communication medium for smart homes, is also developing at the same time. However, the security damage from cyber attacks, which are vulnerabilities in IoT technology, is also increasing in proportion to these developments. In this paper, mirror is implemented as an IoT service hub. It can be used in any space where a mirror is installed, and gesture recognition allows control of existing infrared-based devices as well as certain compatible devices. In addition, the system to solve security problems was implemented by applying AES algorithms between all data communications.

As modern people's interest in health grows, wearable healthcare-related technologies that can collect biometric information and receive health-related services regardless of time and place are developing. This paper proposes the healthcare system based on voice recognition function. Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

목 적 : 전위된 소아 상완골 과상부 골절의 치료에서 도수 정복 후 석고 고정술 또는 경피적 K-강선 고정술을 시행하거나 도수 정복이 되지 않은 경우 최소 피부절개를 통한 관혈적 정복 및 경피적 K-강선 고정술을 시행한 결과를 분석하고자 하였다. 대상 및 방법 : 전위된 상완골 과상부 골절(Gartland 제 Ⅱ, Ⅲ형)로 치료한 8세 이하의 환아중 1년 이상 추시가 되었던 총 74명 (74 골절) 을 대상으로 하였다. Gartland분류에 의한 제 Ⅱ형이 19차례, 제Ⅲ형이 52차례 이었고 정복의 기준은 건측의 주관절 Bauman 각으로 하였다. 안정적인Gartland 제 Ⅱ형, 6례에서 석고 고정을 시행하였고 불안정한 Gartland 제 Ⅱ형 13례와 Gartland 제Ⅲ형 52 례는 경피적 K-강선 고정술을 시행하였다. 도수 정복이 되지 않은 20례 (제 Ⅱ 형 1례, 제 Ⅲ 형 19례)의 경우, mini C-arm 영상하에 주관절 후면에 최소절개를 가하고 소절골도를 이용하여 정복하였다. 결과의 분석에는 주관절 운반각과 기능적인 운동범위의 소실 정도에 따른 Flynn의 분류를 사용하였다. 결과 : 저자들의 결과를Flynn의 분류에 따라 분석하면, 운반각의 경우 excellent는 52 례 (73.2%). good은 13례(18.3%) 로 만족할 만한 결과는 91.5% 이고 운동 범위의 경우 excellent는 49례 (69.0%), good은 20례(28.2%) 로 만족할 만한 결과는 97.2% 로서 비슷한 결과를 보였다. 도수 정복 및 경피적 K-강선 고정술이 운동 범위 요소(Functional factor)에서 더 많은 excellent, 그리고 최소 절개를 이용한 관혈적 정복 및 경피적 K-강선 고정술은 운반각 요소(Cosmetic factor)에서 더 많은 excellent를 나타내었다. 결 론 : 소아의 상완골 과상부 골절의 치료는 소아 골단의 성장판의 손상과 향후 발생할 수 있는 각변형을 고려하여 되도록 정확하고 세심한 정복과 안정적인 고정을 요한다. 또한, 도수 정복이 불가능할 경우 무리한 도수 정복 조작을 계속하지 말고 관혈적 정복을 시행하며 연부조직 손상을 줄이기 위해 가능한 최소 절개를 통한 정복 및 경피적 K-강선 고정을 하는 것이 좋은 결과를 나타내는 것으로 생각된다. Purpose : We evaluated the results of the displaced supracondylar fractures in children treated by closed reduction and cast immobilization, closed reduction and crossed K-wires fixation. Materials and Method : We retrospectively reviewed the results after 1 years of the treatment of 71 extension-type fractures (Gartland type Ⅱ-19 cases, type Ⅲ-52 cases) of supracondylar humeral fractures in children under age of 8 years. Closed reduction was impossible in 20 cases (1 type Ⅱ, 19 type Ⅲ) and we performed open reduction with minimal incision and cross percutaneous pinning. We measured Baumanns angle and range of motion of elbow and evaluated the results by Flynns criteria. Result : By Flynns criteria, 91.5 % of satisfactory (excellent, good) resuts in cosmetic factor and 97.2 % in more excellent in functional factor and that of the minimal open reduction and percutaneous pinning in cosmetic factor but over all satisfactory results were similar. Conclusion : The treatment of the displaced supracondylar humeral fractures in children need accurate and delicate reduction and firm fixation to prevent deformity and to preserve function of the elbow. Open reduction with minimal incision instead of general incision for the manually irreducible supracondylar humeral fracture would be a reliable and convenient method for the treatment of supracondylar humeral fractures in children.

The objective of this study was to compare the farm efficiency of members of cooperative firms with that of non-members in Korea. Data were collected from 27 farms members of three cooperatives and 13 non-member farms, based on the managerial achievements of 1999. For the analysis, the data were divided into three different farming types: type I and Ⅱ of member farms and non-member farms. Economic analysis were implemented using DEA(Data Envelopment Analysis). Major findings was as follows. Total average technology efficiency was 0.782, which implies that there still remains 21.8% of improvement possibility. Among the time types, type I showed the highest technology efficiency of 0.9055, while " 11 and non-member farms showed 0.7670 and 0.7171, respectively. This means that these farms have relatively high potential improved. Also, comparing technology efficiency by dividing into pure technology and scale efficiency, all type of the farms exhibit a higher pure technology efficiency compared to scale efficiency. Therefore, to improve current technology efficiency, farms need to focus more on pure technology efficiency improvement. Meanwhile, profit analysis based on farm size indicate that most of the farms demonstrated the increasing-return-to-scale, which means it is necessary to extend the farm size to improve technical efficiency. Type I member farms achieve higher profit and efficiency than other two types and relatively higher producer prices through introducing cooperative sorting, grading and packing. Also, these labor saving technologies increased farm size.

The radial error motion of a machine tool cutter/spindle system is critical to the dimensional accuracy of the parts to be machined. This paper presents an investigation into spindle run-out effects on cutting mark and surface roughness. We experimented the effects of spindle run-out on surface roughness in flat-end milling by cutting AL 7075 workpiece in various cutting conditions. In order to analyze the effects of run-out on the surface roughness, the spindle's radial error motions was measured by mounting a sphere target onto the spindle as a reference. From the experimental results, it was found that spindle run-out makes a directive effects on surface roughness in flat-end milling.

Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristics radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.
