Development of sit-to-stand assistive chair using a pneumatic cylinder: a feasibility test
홍성균,이규창 물리치료재활과학회 2020 Physical therapy rehabilitation science Vol.9 No.3
Objective: The purpose of this study was to develop and investigate the feasibility of a sit-to-stand assistive chair using a pneumatic cylinder. Design: Cross-sectional study. Methods: The sit-to-stand assistive chair was developed to assist the sit-to-stand movement by rising up of the chair by a pneumatic cylinder. After the user is seated on the chair, if the pneumatic cylinder pulls the seat plate when standing up, the spring of the pneumatic cylinder, which has been stretched, assists in rising the rear end of the seat plate so that the user can stand conveniently and comfortably. A feasibility test was performed in 10 heathy adults. The electromyographic muscle activation of the trunk and lower extremity muscles was analyzed, which included the erector spinae, rectus abdominis, quadriceps, tibialis anterior, gastrocnemius when standing up from sitting using the developed chair and standing up without using the developed chair. Results: As a result, the sit-to-stand assistive chair using a pneumatic cylinder was developed. In the feasibility test, the use of the developed chair had a decrease in rectus abdominis, quadriceps, tibialis anterior activation compared to those who did not use the device in the healthy adults. Conclusions: The sit-to-stand assistive chair using a pneumatic cylinder may be helpful to reduce the activation of the rectus abdominis, quadriceps, tibialis anterior muscles when performing a sit-to-stand movement. Through the results, the efficacy of the sit-to-stand assistive chair can be confirmed. In the future, further studies are warranted to investigate for the safety and efficacy of its use in the elderly population or those who are disabled.

12주간의 수중운동이 뇌성마비 청소년의 견관절 등속성 근기능에 미치는 영향
홍성균 대한통합의학회 2019 대한통합의학회지 Vol.7 No.3
Purpose: The present study investigated the effects of 12-week aquatic exercise training on isokinetic muscle function of the shoulder in adolescents with cerebral palsy. Methods: The study included four male and four female adolescents with cerebral palsy. Isokinetic muscle function was measured at an angular velocity of 60°/s, using Biodex System VI Pro. The peak torques of internal rotation and external rotation were measured before and after training. Aquatic exercise training was performed once a day for 120 min, 4 times a week for 12 weeks. Results: The peak torque of external rotation according to body weight and mean power of internal rotation were significantly higher after training (p < 0.05). Conclusion: Our findings suggest that 12-week aquatic training for adolescents with cerebral palsy can improve isokinetic muscle function of the shoulder. Future studies should analyze the changes in isokinetic muscle function of the shoulder in more detail using various aquatic exercise programs to investigate their effects on individuals with cerebral palsy. 목적: 연구의 목적은 뇌성마비 아동들을 대상으로 12주간의 수영 훈련이 견관절의 등속성 근기능에 미치는 영향을 연구하는데 목적이 있다. 연구방법:자 뇌성마비 청소년 4명과 여자 청소년 뇌성마비 아동 4명을 선정하였다. 훈련 전, 후의 차이를 비교하기 위해 바이오덱스 장비를 이용하여 등속성 근기능을 측정 하였으며, 60°/sec의 각속도에서 절의 내회전과 외회전을 각각 측정하였다. 수중 운동은 하루에 120시간 주 4회 12주간 수행되었다. 결과: 훈련 후 견관절의 외회전에서 단위체중당 최대 우력이 유의하게 증가 하였으며, 내회전에서 평균파워가 유의하게 증가 하였다(p<.05). 결론: 12주간의 수중 운동은 피험자들의 견관절 근기능의 향상을 가져올 수 있었다. 하지만 뇌성마비아의 신체조성 및 근기능에 관한 아직도 많은 분야의 연구가 필요할 것으로 생각 된다.

Up to now, current treatment for headaches have relied upon .direct pharmaceutical medication. However, recent findings suggest that there is a greater need for a variety of treatment technics for physical therapy. This is especially true for people who suffer headaches. Their usual method for pain relief is to go to a hospital or a pharmacy for a pharmaceutical treatment. Repeated ingestion of prescribed medication, however, lead to abdominal difficulties and in some cases, addiction. A proper understanding and application of the oriental "Ki" method could solve this problem and lead to an effective treatment of headaches.

장외파생금융거래에 사용되는 ‘ISDA 기본계약서’상의 선행조건 조항 - 계약해석 및 도산법상의 쟁점을 중심으로 -
홍성균 한국상사법학회 2015 商事法硏究 Vol.33 No.4
Section 2(a)(iii) of the ‘ISDA (International Swaps and Derivatives Association) Master Agreement’, which is a standard contract form used in most international financial derivatives contracts, provides that each payment obligation of each party is “subject to the condition precedent that no Event of Default or Potential Event of Default with respect to the other party has occurred and is continuing.” This so-called ‘flawed-asset clause’ (“Condition Precedent”) has been one of the most controversial issues on derivatives contracts that came up after the bankruptcy of Lehman Brothers. The function of Condition Precedent can be analyzed in two ways. Firstly, it reduces the credit risk of non-defaulting party. This is similar to the right of the obligor in executory contracts provided in the section 536(2) of Civil Code of Korea, which exempts the obligor if the counter party cannot reasonably be expected to perform its own obligation. Secondly, by permitting the non-defaulting party not to perform, Condition Precedent allows her to determine when to exercise the right to Early Termination of the master agreement, and gives her breathing space. Accordingly, this provision does not preclude the Early Termination or the settlement of defaulted contracts; rather, this provides the preparatory phase of Early Termination. In the face of the bankruptcy of Lehman Brothers and the Great Recession, however, non-defaulting parties who were out of money refused to either perform their payment obligation in pursuance of the Condition Precedent or give the notice of Early Termination, which resulted to the prolonged unsettlement of those defaulted transactions. This seemed to be too harsh for the defaulting party, and several interpretations limiting the way Condition Precedent operates were brought up, bringing conflicting court decisions in England. These issues include: whether payment netting, provided in section 2(c) of the Agreement, could apply when the Condition Precedent is not satisfied; whether the Condition Precedent is of an ‘once-and-for-all’ character; and what happens to the payment obligation if the Condition Precedent is not satisfied until the maturity date. It seems that on most of those issues, under contract law of Korea, which takes a rather textualistic approach to contract interpretation, the Condition Precedent would be interpreted similar to the most recent English decision, in which the court stressed “commercial reasonableness.”Moreover, there have been several attempts to limit Condition Precedent where the Event of Default is a “bankruptcy,” in which case the Condition Precedent results in depriving the insolvent party of his right to payment, the asset which could have been available to other creditors pari passu. In this regard, applying Condition Precedent to the insolvent counter party provokes “anti-deprivation principle” in England and “prohibition of ipso facto clause” in the US Federal Bankruptcy Act. Although no provision in the Rehabilitation and Insolvency Act of Korea, which governs the insolvency procedure commenced in Korea, prohibit the ipso facto clause, the Condition Precedent would be invalid in two exceptional cases: where a non-defaulting party neither pays nor gives Early Termination notice for such a long time that this kind of opportunistic behavior is deemed as abandoning the right to safe-harbour clause in the Act; and where the relevant master agreements govern only the transactions such as prepaid swaps or plain vanilla options. As regards to the latter, since a non-defaulting party has no possibility of bearing credit risk in such transactions, the Condition Precedent does not function as intended; therefore, the interests of insolvent’s other creditors should prevail.
