  • Objectives : The purpose of this study was to investigate the clinical effects of Dong-qi acupuncture on piriformis for herniated intervertebral disc(HIVD) of lumbar spine patients with piriformis muscles tenderness. Methods : This research was carried out on the 60 inpatients who received treatment for their HIVD of lumbar spine from January 1 to May 31, 2014 in DaeJeon Jaseng Hospital of Korean Medicine. We divided them into two groups ; group A(n=30) : common treatment on HIVD of L-spine without Dong-qi acupuncture on piriformis(acupuncture, pharmacopuncture, herb medication, Chuna and physiotherapy), and group B(n=30) : common treatment on HIVD of L-spine with Dong-qi acupuncture on piriformis. We evaluated the treatment effect of each group on tenderness(checked by Algometer pressure), and with a numeric rating scale(NRS), and oswestry disability index(ODI). The evaluations of tenderness were performed 8 times : admission day, and on the 3rd, 6th, 9th, 12th, 15th, 18th and 21st day after admission. The evaluations of NRS and ODI were performed 3 times : admission day, and on the 12th and 21st day after admission. The statistical significance was evaluated by SPSS 18.0 for Windows. Results : In group B, tenderness was significantly decreased compared with group A. The difference of tenderness from admission day to the 12th day showed significant reduction compared with group A. Conclusions : Dong-qi acupuncture is more effective in reducing piriformis muscle tenderness in the early stages of treatment. We expect that patients who receive Dong-qi acupuncture will be satisfied with Korean medical treatment and trust their doctor.

  • Objectives The purpose of this study is to investigate characteristics of low back pain patients and trends of Korean medicine conservative treatment effects of low back pain patients by registry data. Methods A total of 78 patients were analyzed, statistical analysis was performed using a generalized linear model. The comparison between groups was performed using independent two samples t-test or Wilcoxon rank sum test according to the distribution of normality. Before and after the treatment effects, ANOVA and Kruskal-Wallis method were used for the comparison, Sheffe method was used for the post test. Results The average age of hospitalized patients was 31.8 years old and out-patient department (OPD) patients was 44.9 years old. Lots of OPD patients and hospitalized patients were classified to 'Lumbago due to Coexist Qu Stagnation and Bloos Stasis'. Both OPD patients and hospitalized patients classified to 'Lumbago due to Coexist Qu Stagnation and Bloos Stasis' showed statistically significant decrease in RMDQ (Roland-Morris disability questionnaire) and NRS (numeric rating scale) on 1 month and 3 month after clinical research start date. Comparing the treatment effects of Chuna manual therapy, both Chuna group and non-Chuna group showed statistically significant decrease in RMDQ and NRS on discharge date, 1 month and 3 month after clinical research start date. Conclusions We expect that a larger scale registry study will be carried out to provide a higher level of basis for the Korean medical treatment of low back pain.

  • Purpose: To quantify the relationship between perceived pain intensity and psychological variables in a sample of participants with temporomandibular disorder, with or without central sensitization (CS). Methods: A cross-sectional study with nonprobability convenience sampling was conducted from January 1, 2022, to June 30, 2023. Pain intensity (Numeric Pain Rating Scale), anxiety (State-Trait Anxiety Questionnaire, STAI), catastrophizing (Pain Catastrophizing Scale, PCS), perceived stress (Perceived Stress Scale, PSS), and sleep quality (Pittsburgh Sleep Quality Index, PSQI) were assessed. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Co.), which included descriptive and normality analyses and the calculation of strength of multiple correlational regression. Results: A total of 52 (n=34 female 65.4%; n=18 male 34.6%) subjects with diagnosis of temporomandibular disorders (TMD) were finally included. A total of 26 participants (n=26, 50.0%) were cases suffered from CS (TMD-CS mean=46.62±11.24) while the remaining participants (n=26, 50.0%) were the controls (TMD-nCS mean=26.77, standard deviation [SD]=8.42). The pain intensity was moderate in both groups TMDCS (mean=7.62, SD=0.83) and TMD-nCS (mean=7.05, SD=0.86), anxiety (TMD-CS STAI mean=53.27, SD=11.54; TMD-nCS STAI mean=49, SD=11.55), catastrophizing (TMD-CS PCS mean=46.27, SD=9.75; TMD-nCS PCS mean=26.69, SD=4.97), perceived stress (TMDCS PSS mean=30.35, SD=4.91; TMD-nCS PSS mean=26.12, SD=6.60) and sleep quality (TMD-CS PSQI mean=15.81, SD=3.65; TMD-nCS PSQI mean=12.77, SD=2.76) levels were measured in both groups. In TMD-CS and TMD-nCS, higher anxiety levels were moderately and significantly associated with greater pain intensity β=0.4467 (t=2.477, p=0.021) and β=0.5087 (t=2.672, p=0.014). Nevertheless, catastrophizing, perceived stress and sleep quality were not associated to pain intensity in neither of group. Conclusions: In both TMD-CS and TMD-nCS patients, elevated anxiety levels were moderately and significantly associated with increased pain intensity. However, heightened levels of pain catastrophizing, perceived stress, and poor sleep quality were not significantly associated with increased pain intensity in either of the two analyzed groups.

  • Objectives This study aims to find out effect of Korean medicine treatment on managing thoracolumbar compression fractures through retrospective observational study. Methods Among hospitalized patients at the Department of Korean Medicine Rehabilitation from January 1st, 2018 to February 28th, 2023, a total of 24 inpatients who were diagnosed with thoracolumbar compression fractures and received Korean medicine treatment were included in this study. Numeric rating scale (NRS) was used for pain assessment and clinical variables such as sex, symptoms, age, thoracolumbar injury classification and severity (TLICS) scores were collected. For subgroup analysis to analyze factors affecting treatment response, we divided patients into responders and non-responders according to NRS change. For statistical analysis, we compared before/after hospitalization and analyzed distinct features between two groups. Results Most of the patients were in their 70s and 83.33% were female. Average hospitalization period was 24.54±11.91 days. All patients had back pain as their chief complaint and only 2 patients received surgeries. In TLICS, only 1 patient got score 6, which represented surgery indication. After Korean medicine treatment, NRS of almost every patient got lower significantly at the time of discharge (3.02±1.93) than admission (5.52±1.95). Comparing two groups, responders had lower NRS at the time of discharge and TLICS score of them were lower than non-responders. Conclusions Our results show that Korean medicine treatment for thoracolumbar compression fractures was effective in reducing pain. There were distinct clinical features such as age, past history, surgeries between those with significant improvement in pain scores and those who did not.

  • This study was conducted to construct basic data for the selection of elite cows by analyzing the estimated breeding value (EBV) and accuracy using the pedigree of Hanwoo cows in Gyeongnam. The phenotype trait used in the analysis are the carcass weight (CWT), eye muscle area (EMA), backfat thickness (BFT) and marbling score (MS). The pedigree of the test group and reference group was collected to build a pedigree structure and a numeric relationship matrix (NRM). The EBV, genetic parameters and accuracy were estimated by applying NRM to the best linear unbiased prediction (BLUP) multiple-trait animal model of the BLUPF90 program. Looking at the pedigree structure of the test group, there were a total of 2,371 cows born between 2003 to 2009, of these 603 cows had basic registration (25%), 562 cows had pedigree registration (24%) and 1,206 cows had advanced registration (51%). The proportion of pedigree registered cows was relatively low but it gradually increased and reached a point of 20,847 cows (68%) between 2010 to 2017. Looking at the change in the EBV, the CWT improved from 4.992 kg to 9.885 kg, the EMA from 0.970 ㎠ to 2.466 ㎠, the BFT from -0.186 mm to -0.357 mm, and the MS from 0.328 to 0.559 points. As a result of genetic parameter estimation, the heritability of CWT, EMA, BFT, and MS were 0.587, 0.416, 0.476, and 0.571, respectively, and the accuracy of those were estimated to be 0.559, 0.551, 0.554, and 0.558, respectively. Selection of superior genetic breed and efficient improvement could be possible if cow ability verification is implemented by using the accurate pedigree of each individual in the farms.

  • 과피색의 경우 정량적인 지표로서 주로 Hunter $L^*a^*b^*$값을 이용하나 이 값으로 과피색, 과실의 품질을 간접적으로 확인하기에는 어려운 점이 있다. 따라서 본 실험에서는 포도 착색지수로서 제안된 CIRG(Color Index for Red Grapes) 값의 활용도를 평가하여 포도 착색의 객관적인 평가지수로서의 가능성을 검증하고자 하였다. 이를 위해 포도가 착색이 시작되는 시기부터 과립을 채취하여 과피색과 당도, 산도 등의 품질 인자를 측정하여, CIRG 값과의 상관을 분석하고 회귀식을 도출하였다. CIRG 값과 안토시아닌 함량은 CIRG 값이 증가함에 따라 안토시아닌 함량은 지수적으로 증가함을 알 수 있었으며, 결정계수는 '캠벌얼리'와 '흑보석' 모두 0.8500 였다. CIRG 값과 당도는 '캠벌얼리'가 0.7758, '흑보석'이 0.7253으로 높은 결정계수를 나타냈으며, 산도 또한 각각 0.7279, 0.663으로 비교적 높은 결정계수 값을 나타내었다. 따라서 적색포도를 대상으로는 CIRG값이 Hunter $L^*a^*b^*$값에 비해 과실품질을 추정하는데 있어 보다 높은 신뢰성을 가지고 있는 것을 확인하였다.

  • Objectives: Shoulder pain is the third most common musculoskeletal complaint that necessitates physician consultation and significantly diminishes patients' quality of life. In this review, we analyzed clinical studies that investigated the use of Korean Medicine for the treatment of shoulder pain. Methods: We searched the online Korean databases, such as KMBase, DBpia, NDSL, RISS, KISS, and OASIS for clinical studies that report the use of Korean Medicine for shoulder pain. We analyzed the included studies with regard to study design, interventions, evaluations, and results. Results: We analyzed data from the following 29 studies: 14 clinical trials (which included 9 randomized controlled trials) and 15 observational studies (which included 11 case reports). In this review, we observed that post-stroke shoulder pain was the most common cause of shoulder pain, which was reported in 13 out of 29 studies (44.8%), although in actual clinical practice, patients are more likely to present with primary shoulder pain. Most included studies (72.4%) reported manual acupuncture as the most common intervention for shoulder pain. More than 50% of the studies used range of motion (58.6%) and the numeric rating scale (51.7%) to evaluate shoulder function and pain, respectively. Although the result was not statistically significant in all included studies, most studies concluded that Korean Medicine could be considered an effective treatment option in patients with shoulder pain. Conclusions: Based on analysis of studies included in this review, Korean Medicine can be considered useful clinical treatment for shoulder pain.

  • This study was performed to compare carcass traits, sensory characteristics, physiochemical composition, and contents of nucleotides, collagen, and free amino acids among quality grades (QG) and to understand the association between QG and above parameters in loin and rump of Korean cattle steer. Loin and rump samples were obtained from 48 Korean cattle steers with each of four QG (QG 1++, 1+, 1, and 2; average 32 months of age). Carcass weight and marbling score (MS) were highest in QG 1++, whereas texture score measured by a meat grader was highest in QG 2. A correlation analysis revealed that MS (r = 0.98; p<0.01) and fat content (r = 0.73; p<0.01) had strong positive correlations with QG and that texture had a strong negative correlation (r = -0.78) with QG. Fat content in loin was highest but protein and moisture contents were lowest in QG 1++. Our results confirmed that a major determinant of QG is the MS; thus, intramuscular fat content. The International Commission on Illumination $L^*$, $a^*$, and $b^*$ values in loin were highest in QG 1++. Numeric values of shear force in loin were lowest in QG 1++, whereas those of tenderness, juiciness, and overall acceptability tended to be highest in QG 1++ without statistical significance. QG was strongly correlated with juiciness (r = 0.81; p<0.01) and overall acceptability (r = 0.87; p<0.001). All sensory characteristics were higher (p<0.05) in loin than those in rump. Adenosine-5'-monophosphate (AMP) and inosine-5'-monophosphate (IMP) contents in both loin and rump did not differ among QGs. No nucleotide (AMP, IMP, inosine, hypoxanthine) was correlated with any of the sensory traits. Total, soluble, and insoluble collagen contents in loin were higher in QG 1++ than those in QG 1. All three collagens had lower content in loin than that in rump. All three collagens were positively correlated with tenderness, juiciness, and overall acceptability. Glutamic acid content did not significantly differ among the four QGs in either loin or rump. In conclusion, it is confirmed that QG is associated with sensory traits but nucleotide contents in beef may not be a major factor determining meat palatability in the present study.

  • Background: The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP treatment after the initiation of the NHI reimbursement. Methods: We collected data retrospectively or via direct phone calls to patients who underwent ITMP implantation at a single university-based tertiary hospital between July 2014 and May 2016. Pain severity, changes in the morphine equivalent daily dosage (MEDD), any adverse events, and patients' satisfaction were determined. We calculated the financial break-even point of ITMP implantation via investigating the patient's actual medical costs and insurance information. Results: During the studied period, 23 patients received ITMP implantation, and 20 patients were included in our study. Scores on an 11-point numeric rating scale (NRS) for pain were significantly reduced compared to the baseline value (P < 0.001). The MEDD before ITMP implantation was 0.59 [IQR: 0.55-0.82]. The total MEDD increased steadily to 0.77 [IQR: 0.53-1.08] at 1 year, which was 126% of the baseline (P < 0.001). More than a half (60%) responded that the ITMP therapy was somewhat satisfying. The financial break-even point was 28 months for ITMP treatment after the NHI reimbursement policy. Conclusions: ITMP provided effective chronic pain management with improved satisfaction and reasonable financial break-even point of 28 months with 50% financial coverage by NHI program.

  • The Primary type of swinging motion in human movement is that which is characteristic of a pendulum. The two types of pendulums are identified as simple and compound. A simple pendulum consist of a small body suspended by a relatively long cord. Its total mass is contained within the bob. The cord is not considered to have mass. A compound pendulum, on the other hand, is any pendulum such as the human body swinging by hands from a horizontal bar. Therefore a compound pendulum depicts important motions that are harmonic, periodic, and oscillatory. In this paper one discusses and compares two algorithms of Newton's method(F = m a) and Euler's method (M = $I{\times}{\alpha}$) in compound pendulum. Through exercise model such as human body with weight(m = 50 kg), body length(L = 1.5m), and center of gravity ($L_c$ = 0.4119L) from proximal end swinging by hands from a horizontal bar, one finds kinematic variables(angle displacement / velocity / acceleration), and simulates kinematic variables by changing body lengths and body mass. BSP by Clauser et al.(1969) & Chandler et al.(1975) is used to find moment of inertia of the compound pendulum. The radius of gyration about center of gravity (CoG) is $k_c\;=\;K_c{\times}L$ (단, k= radius of gyration, K= radius of gyration /segment length), and then moment of inertia about center of gravity(CoG) becomes $I_c\;=\;m\;k_c^2$. Finally, moment of inertia about Z-axis by parallel theorem becomes $I_o\;=\;I_c\;+\;m\;k^2$. The two-order ordinary differential equations of models are solved by ND function of numeric analysis method in Mathematica5.1. The results are as follows; First, The complexity of Newton's method is much more complex than that of Euler's method Second, one could be find kinematic variables according to changing body lengths(L = 1.3 / 1.7 m) and periods are increased by body length increment(L = 1.3 / 1.5 / 1.7 m). Third, one could be find that periods are not changing by means of changing mass(m = 50 / 55 / 60 kg). Conclusively, one is intended to meditate the possibility of applying a compound pendulum to sports(balling, golf, gymnastics and so on) necessary swinging motions. Further improvements to the study could be to apply Euler's method to real motions and one would be able to develop the simulator.
