Objectives This study was conducted to characterize scoliosis patients visiting Korean medicine hospital and to analyze the demands and factors affecting discomfort. Methods This retrospective study analyzed 33 scoliosis patients who visited Korean medicine hospital from March, 2021 to October, 2021. The data analysis consisted of three factors: (1) demographic characteristics, (2) characteristics of demands on Korean medicine (reasons for choosing Korean medical treatment, preferred treatment methods, most uncomfortable part, treatment priorities) and (3) discomfort factors (treatment experiences, diagnosed age and Cobb's angle). Statistical analyses were performed and a p-value≤0.05 was considered to be statistically significant. Results 43.75% of the patients chose ‘effectiveness’ for the reason why they preferred Korean medicine treatment. ‘Chuna treatment’ was the most preferred treatment method. The patients chose ‘lower back’ for the most uncomfortable part and ‘pain’ for the highest priority of improvement. The Cobb's angle of included patients was 16.02±7.65° and it is not much differ to average of Cobb's angle in Korean. Discomfort was more severe in the patients with treatment-experienced than treatment- naive. The score of discomfort in appearance and psychological were higher in the patients diagnosed in childhood or adolescent period than who were diagnosed after adult. Classification based on Cobb's angle showed no statistical difference. Conclusions Not only Cobb's angle but also other clinical factors should be considered for effective treatment in scoliosis. Also, It is necessary to pay attention to adult scoliosis patients. (J Korean Med Rehabil 2022;32(1):63-72)

The objective was to propose effectiveness of conservative treatments including Korean medical treatments for symptomatic Schmorl's nodes (SNs). We conducted retrospective study that analyzed the medical records of two patients with the symptomatic SNs. They were treated by conservative treatments including Korean medical treatments for 3 weeks. We evaluated numeric rating scale (NRS), Oswestry disability index (ODI) and EuroQol-5 dimension (EQ-5D) index. After treatment, NRS, ODI were decreased and EQ-5D index was increased. We performed literature search to analyze the mechanisms of its treatment and evaluate clinical trials. There were three major mechanisms: (1) Improving constructive stability of vertebrae, (2) alleviating pain, and (3) controlling autoimmunity. When comparing operative treatment (OT) trials and conservative treatment (CT) trials, we couldn't find conclusive basis that support which one is more effective. As OT trials reported some severe adverse events, CT trials reported mild adverse events. The conservative treatments that we used encompasses those mechanisms and is relatively safe. To obtain exact evidence of effectiveness, further studies are needed. (J Korean Med Rehabil 2022;32(1):133-144)

Objectives The aim of this study was to review the current Sasang Constitutions studies on children and adolescents and to provide basic data for developing in a better direction of research. Methods Research articles on children and adolescents of the Sasang Constitutions studies were extracted from six databases. Published year, published journals, types of studies were classified. Subjects of research and clinical methods for the Sasang type classification were summarized, especially in clinical studies. Results A total of 26 selected research articles were published from 1990 to 2013 and 14 articles (54%) have been published in Journal of Sasang Constitutional Medicine and Journal of Pediatrics of Korean Medicine. 96% of the total researches were based on clinical studies. Psychological and physical characteristics by Sasang Constitutional type accounted for most of the clinical research studies subjects. But these studies were not performed with diagnostic tools only for children and adolescents. Discussion In this study, the necessity of developing methods of Sasang constitutional type classification for children and adolescents was confirmed. If accompanied by additional research based on this study, it is expected to be used in diverse fields with active collaboration or education.

The purpose of this study is to evaluate the effectiveness of traditional Korean medicine treatment of cervical vertigo. Three patients were diagnosed as cervical vertigo with correlating symptoms of imbalance and dizziness with neck pain. The diagnosis of cervical vertigo is also dependent on excluding other vestibular disorders on the basis of history, examination, and vestibular function tests. They were treated by acupuncture, transcutaneous electrical nerve stimulation therapy and low-intensity pulsed ultrasound at acupoints and sympathetic ganglion chain of their cervical and upper thoracic region. The evaluation of clinical outcome was done by numeric rating scale (NRS), dizziness handicap inventory (DHI) and neck disability index (NDI), EuroQol-five dimensions questionnaire (EQ-5D) index. After the treatment, the value of their NRS, NDI, DHI was significantly decreased and their EQ-5D index was significantly increased. The traditional Korean medicine treatment at cervical and upper thoracic region could be an effective way to treat cervical vertigo. (J Korean Med Rehabil 2022;32(1):145-155)

The purpose of this study is to report the effects of electroacupuncture and bee venom (BV) acupuncture for a patient suffering with idiopathic peripheral neuropathy. There was a one patient who was diagnosed as idiopathic peroneal neuropathy and tibial neuropathy received electroacupuncture and BV acupuncture at acupoints on peroneal and tibial nerve pathway. The evaluation of clinical outcome was done by range of motion (ROM), manual muscle test (MMT), perimeter of lower leg, neuropathy pain scale (NPS). After treatment, the patient showed improvement in ROM and MMT. The patient’s perimeter of lower leg was increased, NPS was decreased. This study suggests that the treatment of acupoints on the damaged nerve pathways could be an effective treatment for peripheral neuropathy, although further studies will be needed.

본 연구는 2002~2017년 기간의 비금융 상장기업을 대상으로 공정거래법에 따라 설립된 지주회사(이하 지주회사)가 다른 기업(이하 비지주회사)에 비해 기업가치가 저평가 되어 있는지 분석하고 그 원인을 탐구하였다. 분석 결과 지주회사의 자기자본 시장가치-장부가치 비율(M/B equity)의 평균은 0.654로 1에 훨씬 못 미치며, 비지주회사에 비해 유의적으로 낮은 디스카운트 현상이 존재함을 발견하였다. 이 디스카운트는 기업집단 내의 자·손자회사와 비교해도 유의하며, 기업가치에 영향을 미치는 변수들을 통제한 다변량 회귀식에서도 유의하였다. 또한 Campello and Graham(2013)의 방법론을 사용한 결과 지주회사는 기업펀더멘탈에 비해서도 낮은 기업가치를 나타내었다. 한편 사실상의 지주회사(공정거래법상 지주회사는 아니지만 기업집단의 지주회사 역할을 하는 사업회사)의 기업가치는 저평가되어 있지 않았으며, 따라서 지주회사 디스카운트는 공정거래법상 지주회사에 대해서만 나타나는 현상임을 알 수 있었다. 지주회사 디스카운트의 원인을 명확히 밝히기는 힘들지만, 지주회사 주식의 거래회전율이 타 주식에 비해 상당히 낮고 지주회사 전환 후에 급격히 하락하는 것으로 보아 투자자들은 고유사업이 없고 자회사 통제관리를 목적으로 하는 지주회사를 매력적인 투자대상으로 생각하지 않는 것으로 추측된다. 또한 대부분의 지주회사는 사업자회사가 함께 상장 되어 있는데, 투자자들은 지주회사보다는 사업자회사 쪽으로 투자수요를 집중하여 지주회사 디스카운트가 발생하거나 심화되는 것으로 추측된다. 일본의 지주회사에게는 디스카운트 현상이 없는 것으로 보이며, 지주회사 디스카운트는 한국시장 특유의 현상인 것으로 보인다. This study finds that holding companies (i.e., those that are founded pursuant to Korea’s Monopoly Regulation and Fair Trade Act) are traded at lower values than are other companies in the stock market. Our investigation of listed firms over the period 2002~2017 reveals that the mean and median market-to-book equity ratios of holding companies are significantly below 1 and substantially lower than those of other companies. This valuation discount remains significant even when comparing holding companies with their subsidiaries and in multiple regressions that control for various firm characteristics and business-group fixed effects. Furthermore, holding companies’ values are significantly lower than their fundamental values as estimated using Campello and Graham’s (2013) method. In comparison, de facto holding companies, which are defined as operating firms that serve as holding companies for business groups, do not display a valuation discount. Our results show that the holding company discount is related to investors’ tendency to shun holding companies, as indicated by the relatively small turnover of holding companies’ stocks. Additionally, the holding company discount may arise partly because most holding companies are listed together with their operating subsidiaries, and investors concentrate their demand on (pure-play) operating-subsidiary stocks, rather than on holding-company stocks. It appears that the holding company discount is a phenomenon unique to Korea, as similar discounts are not found in the stock markets of Japan or the United States.

This study was performed to evaluate the effect of high frequency therapy applied to the region branching to the external carotid artery for peripheral facial paralysis sequelae. A patient suffering with facial edema due to facial paralysis sequelae had been treated with acupuncture, high frequency therapy on the branch area to the external carotid artery for 7 weeks. The evaluation of clinical outcome was done by degree of swelling by measuring the distance of the face and skin temperature of face through digital infrared thermographic imaging. After treatment, the patient's degree of swelling and the temperature difference between the affected side and normal side was decreased. In addition, the temperature was changed in the entire facial area as well as the treatment point of high frequency therapy. This result shows that acupuncture combined with high frequency therapy at the region branching to the external carotid artery could be an effective way to improve facial blood flow, although further clinical studies will be needed.
