The first Cybathlon will be held in October 2016 and this contest is designed for developing prosthetic technologies. In this study, we analyzed the Cybathlon and from this analysis we researched advanced prosthetic technologies. In addition, we ascertained some ethical issues about post-human beings with prosthetic equipment, which could rehabilitate disabled people and even serve to enhance non-disabled people. Disability is only one of the inconveniences that a person must endure, but everyone has some sort of inconvenience to endure. We found the possibilities of dissolving boundaries between people with disabilities and their able-bodied counterparts through the Cybathlon and prosthetic devices. The features and role of our body itself will be expanded with the help of these future technologies. Engineers, inventors and designers are making better prostheses for disabilities, but these could help not only disabled people but also every non-disabled people. The dominant ethical debates that appear in bioethics and human- related enhancement are reliability, authenticity and autonomy. Reliability and autonomy are the question of being safe and controllable. In this study, we want to raise a question on authenticity: ‘if a person with a powered-prosthesis sets a better record, should we admit it?’

Purpose: The aim of this study is to determine the effect of glenohumeral (GH) rotation position in modified knee push-up plus exercise (MKPUP) by examining the surface electromyography (EMG) amplitude in serratus anterior (SA), pectoralis major (PM), and upper trapezius (UTz) and the activity ratio of each muscle. Methods: A total of 22 healthy subjects volunteered for the study. Each subject performed the MKPUP at $0^{\circ}$, $45^{\circ}$, and $90^{\circ}$ of GH joint internal rotation. EMG of the SA and PM, UTz was compared between GH rotation positions and each muscle activity ratio. EMG was used to measure the muscle activity in terms of ratios to maximal voluntary isometric contraction (MVIC). Results: The difference in EMG activity during the exercise in three GH joint internal rotation positions was observed with the SA and the PM. The greater the GH joint internal rotation angle was, the lower the activity of the PM. In contrast, the SA showed higher activity. However, the activity of UT was similar under all conditions. The ratio of the SA and the PM was considerably greater at $90^{\circ}$ GH joint internal rotation than at $0^{\circ}$ and $45^{\circ}$. Conclusion: When excessive activation of the PM or imbalanced activation between the PM and the SA occurs, the MKPUP exercise is most effective at $90^{\circ}$ of GH joint internal rotation. Use of this position would be a beneficial strategy for selective strengthening of the SA and minimizing PM activation.

Purpose: The aim of this pilot study was to determine the effect of soft tissue technique (STT) in Axillary Web Syndrome (AWS) following sentinel Lymph Node Biopsy in breast cancer patients by examining the upper extremity function, range of motion, and pain. Methods: Nineteen patients with breast cancer-related AWS were evaluated. STT was performed on the symptom area for treatment of AWS symptoms. We evaluated AWS symptoms and pain intensity using a visual analogue scale (VAS), and functional disability using the Korean version of the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire, glenohumeral joint (GHJ) flexion and abduction range of motion (ROM) with or without elbow extension. Results: Visual analyses of the data suggest a modest effect of STT in improving GHJ flexion, abduction ROM with or without elbow extension, DASH for upper extremity function, and Pain. The statistically significant improvement in baseline observed for pain, DASH, and ROM data made it impossible to assess the effects of STT on those outcomes. There were no adverse events. Conclusions: STT may be an effective and safe treatment option for AWS patients recovering from breast cancer treatment; however, further research is needed.
Anti-inflammatory and radical scavenging properties of Verbena officinalis
Shim, Hwan-Ki,Kim, Seong-Yeol,Kim, Bo-Rim,Cho, Jae-Park,Park, Yae-Jeong,Ji, Won-Geun,Cha, Dong-Seok,Jeon, Hoon Kyung Hee Oriental Medicine Research Center 2010 Oriental pharmacy and experimental medicine Vol.10 No.4
Verbena officinalis (Verbenaceae) has been used as herbal medicine or health supplement in both Western and Eastern countries for centuries. In the present study, we examined the anti-inflammatory and antioxidant activities of the methylene chloride fraction of V. officinalis (VMC). To elucidate the anti-inflammatory properties of VMC, we investigated the inhibition effects of nitric oxide production in interferon-gamma (IFN-$\gamma$) and lipopolysaccharide-stimulated mouse peritoneal macrophages. VMC suppressed nitric oxide production, inducible nitric oxide synthase and cyclooxygenase-2 expression dose-dependently without notable cytotoxicity. In various radical scavenging assays, VMC exhibited strong scavenging effect on DPPH radical, superoxide radical, nitric oxide radical and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radical. VMC also showed potent reducing power. These findings strongly suggest that VMC may be beneficial in oxidative stress-mediated inflammatory disorders.
Polscope-Assisted Enucleation for Nuclear Transfer in Mice

Efficiency of somatic cell nuclear transfer was investigated in mice. First, oocyte activation was induced by SrCl₂, and the rate of development was compared with embryos from normal fertilization. Although more than one half of SrCl₂-treated oocytes developed to blastocysts (146/262, 55.7%), the rate of blastocyst formation was significantly lower than normal fertilization controls (59/79, 74.6%). Second, enucleation of oocytes was performed using Polscope that enables non-invasive visualization of metaphase spindles. Such approach could not only avoid damage of oocytes during an exposure to UV light often employed in conventional enucleation procedures, but could also assure the removal of nuclei from all oocytes operated because of monitoring the location of spindles during an entire process of enucleation. Morphologically normal blastocysts were obtained from the transfer of cumulus cell nuclei into enucleated oocytes. However, the rate of development into the blastocyst stage was still low (4/93, 4.3%). This reflects that the nuclear transfer procedure used in this study was not sufficiently optimized, and other factors may also impact greatly the efficiency of nuclear transfer. Including an induction of oocyte activation and method of enucleation tested in this study, a lot more elements are remained to be optimized to improve the efficiency of somatic cell nuclear transfer in mice.
Constructing Images through Art Exhibitions

1920년경부터 30년대 초반까지, 조선의 정체성에 대한 고민은 문화 전반에 걸쳐 나타났다. 이 논문은 그 중 하나인 향토색 논쟁을 미술전람회를 중심으로 살핀다. 조선의 고유한 향토색을 찾으려는 조선인의 민족주의적 노력과 일본이 제국주의적 시각으로 제국의 일부로서 자신을 정의하도록 하는 정책과의 중첩지점에는 조선을 어떻게 표상하느냐를 둘러싼 각기 다른 그룹들 사이의 갈등이 있었다. 이 논문은 식민지 문화통치의 일환인 조선미술전람회가 민족주의적 성격을 지닌 서화협회를 견제하고 헤게모니를 장악하여 어떤 방식으로 향토색 논쟁에 개입하는지 살핀다. 조선미술전람회를 통해 조선의 향토색을 보다 시골적, 원시적, 여성적인 이미지, 또 일본 문화의 영향을 받은 이미지로 길들여가는 과정을 살필 수 있었다. The cultural nationalist endeavor to preserve Korean culture and find “Koreanness” in many realms applied to art and culture. The search for Korean identity invigorated the local color debate. This paper examines the political implications of the local color debate, focusing on the Chosǒn Art Exhibition which was established and funded by Japanese colonial authorities in order to minimize the organized efforts of Korean nationalist artists at Sǒhwa Hyǒphoe. This paper examines the ways in which the Chosǒn Art Exhibition hinders the search for Koreans’ own identity in uncontrolled venues as the Sǒhwa Hyǒphoe Exhibition. The Cultural Rule tried to achieve such control subtly, through the establishment of cultural sites such as the Chosǒn Art Exhibition, in which artists could take part and be policed at the same time. The Chosǒn Art Exhibition became the very influential venue for the artists and the jury of the Japanese authorities encouraged to search for the local color of Chosǒn which caters to their taste. As a result, the primitive or rural self-images and images influenced by Japanese culture came to dominate the Korean artworks. This paper tries to show the ways in which Japan intervened in the development of Korea’s self-image through the modern institution of art exhibitions.
