This study is carried out to examine the effect of applying Feldenkrais method, elastic band training and combined training on trunk muscle. The subjects of this study were 32 modern dance majors and they were divided into four groups which consists of 8 peoples each, Feldenkrais method group(modern dance + Feldenkrais method), elastic band training group(modern dance + elastic band training), combined training group(modern dance + Feldenkrais method + elastic band training), and control group(modern dance). Measurement variables which are trunk muscle were measured before training, and after 4 and 8 weeks training and the results are as follow: In the left muscle strength change at Centaur 0°, Feldenkrais method group, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and combined training group had significant increase after 8 weeks training. In the left muscle strength change at Centaur 45°, Feldenkrais method group and combined training group showed significant increase after 8 weeks training compared to before training and after 4 weeks training. Also elastic band training group showed significant increase after 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group and elastic band training group significantly increased after 8 weeks training compared to before training. In the left muscle strength change at Centaur 90°, Feldenkrais method group and combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, Feldenkrais method group showed significant increase after 4 and 8 weeks training compared to before training, and elastic band training group significantly increased after 8weeks training compared to before training. In the left muscle strength change at Centaur 135°, there was no significant changes. In the right muscle strength change, elastic band training group and combined training group showed significant increase after 8 weeks training compared to before training. In the left muscle strength change at Centaur 180°, combined training group showed significant increase after 4 and 8 weeks training compared to before training. In the right muscle strength change, combined training group showed significant increase after 4 and 8 weeks training compared to before training. From above results, applying 8 weeks regular program of Feldenkrais method, elastic band training and combined training to modern dance majors showed positive changes on improvement of trunk muscle strength and physical strength. Also this study implemented to verify the effects of trunk muscle strength and body balance through supplementary training program, and showed the effects in the training group and control group after 8 weeks trunk muscle strengthening program. Feldenkrais method, elastic band training and combined training are very effective to improve trunk muscle strength of modern dance majors so that continuous implementation and application of these effective training program shall be provided for strengthening trunk muscle.

Effect of Total Hip Arthroplasty on Ipsilateral Lower Limb Alignment and Knee Joint Space Width: Minimum 5-Year Follow-up

Choi Yun Seong,Park Jung-Wee,Kim Tae Woo,Kang Kee Soo,Lee Young-Kyun,Koo Kyung-Hoi,Chang Chong Bum 대한의학회 2023 Journal of Korean medical science Vol.38 No.20

Background: This study aimed to 1) assess the effect of total hip arthroplasty (THA) on coronal limb alignment, namely, the hip–knee–ankle angle (HKA), 2) identify factors that determine changes in the HKA, and 3) determine whether alignment changes influence the knee joint space width. Methods: We retrospectively evaluated 266 limbs of patients who underwent THA. Three types of prostheses with neck shaft angles (NSAs) of 132°, 135°, and 138° were used. Several radiographic parameters were measured in the preoperative and final radiographs (at least 5 years after THA). A paired t-test was used to confirm the effect of THA on HKA change. Multiple regression analysis was performed to identify radiographic parameters related to HKA changes following THA and changes in knee joint space width. Subgroup analyses were performed to reveal the effect of NSA change on the HKA change, and the proportion of total knee arthroplasty usage and changes in radiographic parameters between maintained joint space and narrowed joint space groups were compared. Results: The preoperative mean HKA was 1.4° varus and increased to 2.7° varus after THA. This change was related to changes in the NSA, lateral distal femoral angle, and femoral bowing angle. In particular, in the group with a decrease in NSA of > 5°, the preoperative mean HKA was largely changed from 1.4° varus to 4.6° varus after THA. The prostheses with NSA of 132° and 135° also led to greater varus HKA changes than those with an NSA of 138°. Narrowing of the medial knee joint space was related to changes in the varus direction of the HKA, decrease in NSA, increase in femoral offset. Conclusion: A large reduction in NSA can lead to considerable varus limb alignment after THA, which can have adverse effects on the medial compartment of the ipsilateral knee.

Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

재고자산의 변화가 기업의 미래성과 및 평가에 미치는 함의에 관한 실증연구

김창범(Kim, Chang Bum) 한국국제회계학회 2013 국제회계연구 Vol.0 No.48

본 논문은 비기대 재고자산의 변화(ΔCPAI)가 미래성과에 미치는 본질적인 함의를 평가하며, 이러한 함의에 대한 시장의 반응도 함께 분석하였다. 재고자산의 변화가 미래성과에 미치는 함의와 관련한 연구에서 고려해야 할 부분은 크게 2가지이다. 이는 현행 전부원가계산시스템 하에서 재고자산의 변화가 경영자의 기회주의적 이익조작의 결과인지? 혹은 미래 기대매출의 증가를 반영한 신호전달과정인가? 하는 점이다. 이와 관련한 중요한 관심변수로는 해당기업의 원가구조 부분과 수주잔고부분이라 할 수 있다. 이는 고정제조 간접원가의 비중이 큰 제조업의 경우, 매출 수량을 초과하는 재고자산의 증가는 수주잔고가 뒷받침되지 않을 경우, 그렇지 않은 기업군에 비하여 경영자의 이익조작의 개연성이 높다는 점이다. 본 논문에서는 각 기업 집단별로 이를 분류하여 실증하였다. 실증결과, 비기대 재고자산의 변화액은 수주잔고가 뒷받침되는 경우에만 차기성과와는 유의적인 양(+)의 관계를 유지하고 있었다. 즉, 이 경우에는 경영자의 사적전달의 긍정적인 신호(Signal)로 비기대 재고자산의 변화액을 설명할 수가 있었으며, 그 외의 경우에는, 경영자의 이익조작의 수단으로 재고자산이 사용될 가능성이 높았다. 이러한 현상은 비기대 재고자산의 변화액만을 대상으로 한 집단별 추가분석에서도 이와 유사한 결과를 나타내었으며, 재고자산의 변화액과 차기성과간의 음(-)의 관계를 형성하는 주된 동인은 비기대 재고자산의 변화액에 있었다. 그러나 본 논문은 업종의 성격상 적시생산 시스템을 적용하는 제조업의 경우에는 적용하기가 어려운 한계점이 있다. 또한 재고자산의 변화액과 차기성과간의 음(-)의 관계를 형성하는 주된 동인을 비기대 재고자산의 변화액에 있다고 하였으나, 본 논문에서 제외된 기타 동인들에 의해서도 이러한 음(-)의 관계가 초래될 수도 있어서, 향후 이 부분에 대하여도 세심한 연구가 진행되어야 할 것으로 보인다. This study tries to investigate the fundamental implications inherent in inventory asset information(specifically, unexpected inventory investment) by analyzing how the relationship between the changes of unexpected inventory investment and future operating performance. Our empirical results of the study are summarized as follows. Current unexpected inventory changes are negatively associated with future operating performance, which is mainly driven by the abnormal components of inventory changes. Also, the negative relation between the changes of unexpected inventory and future operating performance tended to amplify for firms with high fixed overhead, which suggests the possibility that inventory changes are employed as a tool for managerial earnings management(which is not supported by backlog). Conclusively, the negative relation between the changes of unexpected inventory and future operating performance could be the results of managers" opportunistic behavior. This study contributes to the related study as follows. This study fills the gap in the empirical literature by explicitly examining the role that cross-sectional variation in firms" fixed manufacturing overhead plays in the relation between firms" inventory change and their future accounting performance.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Background: Epidermal cysts (EC) are the most common tumors found on the skin and accompanying inflammation is also frequent. However, the predictors for inflammatory change have not been investigated yet. Objectives: This study was performed to investigate the difference between inflamed and uninflamed epidermal cysts, and to assess associated factors for inflammatory change. Methods: We analyzed the biopsy-proven 1723 epidermal cysts (515 inflamed and 1208 uninflamed) at two tertiary hospitals from 2011 to 2021. Results: The proportion of inflamed epidermal cysts (IEC) and uninflamed epidermal cyst (UIEC) were 29.9 % and 70.1 %, respectively. Inflammatory change was less frequently observed on the face (25.5 %) than the other sites (32.1 %) (p=0.0046). The anatomic location with the highest rate of inflammatory change was back (40.8 %, p=0.0004). Mean duration of inflammatory change from UIEC to IEC on the face was shorter than the other sites (12.5 months vs 17.9 months, respectively, p= 0.0473). On ultrasonography, long axis of IEC (20.7mm) was generally longer than that of UIEC (15.7mm) (p=0.0218). Moreover, Inflammatory change was more frequent on the EC with punctum compared to those without punctum (35.3 % vs 30.3 %, P=0.0471). Conclusion: Based on the location, size and presence of punctum, decision on the optimal treatment strategies can be established when encountering patients with EC.

Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.
