The purpose of this study was to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation on a visual analysis scale and functional visual analysis scale regarding functional capacity. A total of 7 consecutive patients with the complaint of patellofemoral pain syndrome who received this diagnosis from a sports medicine physician were recruited to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation (NMES) on Visual Analog Scale (VAS) and Functional Visual Analog Scale (FVAS), functional capacity patients with patellofemoral pain syndrome. The exercise rehabilitation consisted of a complex training program requiring five treatments a week for eight weeks. The training program consisted of four phases, and each lasted for two weeks. Statistical analyses were one-way ANOVA with repeated measures. The results were as follows: (1) There were significant differences in the VAS and FVAS during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.01). (2) There were no significant differences in the functional capacity during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.05). In conclusion, at the end of the eight weeks of this rehabilitation program and neuromuscular electrical stimulation, a significant reduction was found in VAS and FVAS, but there was no significant difference in functional capacity at the end of the treatment.

This paper develops an OBD Diagnostic Program (Program) using Visual Studio (C#), which was used to diagnosis malfunction information from OBD-II system vehicles. We accomplished this using the Program, Diagnostic tests, Board (STN1110), FTDI Basic Cable, Mini USB Cable, OBD Data Cable, and both hybrid and regular vehicles. The Program tests real-time data output, DTC output, sensor value output, engine RPM, waveform data, OBD type check, PID inspection, and whole monitoring. We found vehicles used in this research had 19 PIDs, which was within OBD-II regulations. We also gathered data on control and diagnostic code regulated by OBD-II system, such as, sensor output value, engine RPM, DTC output, each PID analytic value, OBD type, fuel mode, and whole monitoring result value. Using the data collected through the Program appropriately can lead to more effective diagnostic practices and contribute to education.

Personal image concerns a person's talent, expertise, as well as the internal and external image. It is a core value that differentiates one individual from another. As personal branding via personal image management has become more important, there is a fast-growing number of online systems that provide self-test programs to analyze one's style and habits and also provide expert advice for not only styles but lifestyles as well. This study develops a systematic and objective personal image consulting system and offers basic information for the research of personal image making. For that purpose, the study attempts to examine the present state of global companies that use online image consulting programs and analyze their digital content. The results are as follows: 1) two domestic companies, Colorz and Atzine, and seven foreign companies, notably Covet and Boutique, were brisk in business; 2) two types of personal image-diagnosis programs - Visual search and Virtual matching - are now in operation; and 3) mobile applications exist as an evolved personal image-diagnosis program. With an increased interest in such programs, various companies at home and abroad are establishing systematic and scientific analysis systems, which are needed for personal image-making online. Under these circumstances, domestic companies are also urged to enhance levels of image-diagnosis content and actual commercialization and utilization, to develop programs that enable objectified, systematic personal image-making. To this end, the results of this study may serve as a helpful tool to consider future directions.

Porphyromonas gingivalis (P. gingivalis) is a major bacterial pathogen that causes periodontitis, a chronic inflammatory disease of tissues around the teeth. Periodontitis is known to be related to other diseases, such as oral cancer, Alzheimer's disease, and rheumatism. Thus, a precise and sensitive test to detect P. gingivalis is necessary for the early diagnosis of periodontitis. The objective of this study was to optimize a rapid visual detection system for P. gingivalis. First, we performed a visual membrane immunoassay using 3,3',5,5'-tetramethylbenzidine (TMB; blue) and coating and detection antibodies that could bind to the host laboratory strain, ATCC 33277. Antibodies against the P. gingivalis surface adhesion molecules RgpB (arginine proteinase) and Kgp (lysine proteinase) were determined to be the most specific coating and detection antibodies, respectively. Using these two selected antibodies, the streptavidin-horseradish peroxidase (HRP) reaction was performed using a nitrocellulose membrane and visualized with a detection range of 10³-10⁵ bacterial cells/ml following incubation for 15 min. These selected conditions were applied to test other oral bacteria, and the results showed that P. gingivalis could be detected without cross-reactivity to other bacteria, including Streptococcus mutans and Escherichia fergusonii. Furthermore, three clinical strains of P. gingivalis, KCOM 2880, KCOM 2803, and KCOM 3190, were also recognized using this optimized enzyme immunoassay (EIA) system. To conclude, we established optimized conditions for P. gingivalis detection with specificity, accuracy, and sensitivity. These results could be utilized to manufacture economical and rapid detection kits for P. gingivalis.

맥진은 한의 진단에 있어 중요한 요소이나 맥진 교육에 있어서 수련자와 교육자 간에 언어적 표현 외에는 적절한 교육 정보 소통의 도구가 없어 정량적이며 과학적 교육이 어려운 실정이다. 이에 본 논문에서는 맥진 시 한의사가 세 손가락을 통해 맥진 부위에 가하는 가압력 프로파일을 정량적으로 측정할 수 있는 하드웨어와 이를 기반으로 맥진 동작을 트레이닝할 수 있는 프로그램을 개발하였다. 가압력 프로파일 측정 하드웨어는 인조 팔 속 맥진 위치에 놓인 3개의 로드셀과 맥진 가압력 신호를 증폭하는 증폭부 및 상용 A/D 변환 모듈인 NI-USB 6009로 구성하였으며, 3채널 가압력 신호는 200Hz로 샘플링하였다. 하드웨어 출력 신호를 질량 값으로 교정할 수 있도록 $50{\sim}500g$ 범위의 8개 추를 인조 팔에 올려놓았을 때의 질량 대비 출력전압 테이블을 작성하였다 또한, 이 시스템을 통해 한방 전문의 3명의 맥진 가압 프로파일을 각 3회씩 측정해 보았으며, 이를 통해 한의사의 맥진은 크게 3개의 구간으로 나눌 수 있고 최대 가압력이 약 $500g{\cdot}f$인 것 등을 알 수 있게 되었다. 맥진 가압트레이닝 프로그램은 LabView를 통해 구현하였으며, 수련자가 미리 저장된 목표 맥진 가압 프로파일과 유사하도록 인조 팔을 맥진할 때의 가압 프로파일이 목표 가압 프로파일과 유사한 정도를 평가하여 일정 범위를 벗어나면 경고하고, 실습이 끝나면 목표 프로파일과 유사도 점수를 화면에 표시하도록 하였다. 더 나아가 유사도 점수의 추이를 통해 숙련 추이를 관찰 할 수 있도록 하였다. 이 시스템을 맥진 교육에 활용한다면 보다 정량적이며 과학적인 교육이 가능해질 뿐만 아니라 교육의 효율도 크게 향상될 것으로 기대된다.
