The purpose of this study is to figure out the effect of 12 weeks pilates program for body shape improvement and lumbar stabilization of senior women with chronic back pain and to provide data for developing excercise program which is appropriate for senior women to make aging delayed and to have more physical activity domain by inquiring into their pain reducing. The subjects of this study were 16 senior women with chronic back pain which were classified into two group with experimental group(n=8) and control group(n=8) by applying simple random sampling after conducting Visual Analogue Scale(VAS). Their motion range of pain was from 3 centimeters to 5 centimeters. Pilates excercise for lumbar stabilization in this study was originated the previous literature of Lee et al(2011) and the excercise was modified in the form of pilates. The program in the study was performed under the guidance of a professional pilates trainer. The results are as follows. Firstly, the experimental group showed positive improvement in making vertebra slope but the control group showed pain increased. Secondly, the lumbar pain decreased in the experimental group but it increased in the control group. As a result, the pilates program for lumbar stabilization can be considered as a program for pain relief and body shape improvement of senior women with chronic back pain.

This study discovers the general characteristics of B-class Emotional Advertisements and analyses their trend. A content analysis was conducted on 498 advertisements on-aired between 2015 and 2020, which were sampled from the advertisements registered in the TVCF(www.tvcf.co.kr), the largest advertisement web portal in the Republic of Korea. The analysis concludes that the B-class Emotional Advertisements, employed in a wide range of genre, is most incorporated in comedy/exaggeration genres and is on a rising trend due to 2020 COVID-19 Pandemic. Furthermore, it is confirmed that the utilization of B-class emotional advertisement has also increased in domain of non-commercial advertisements, such as Public Service Advertisements, Governmental/Organizational Advertisements, and Corporate Public Relations (PR) Advertisements. The study validates the transformation of the B-class emotional advertisements from a demonstration of an eccentric minority subculture to an epitome of a new and adventurous mainstream culture, successfully serving a central role in both the commercial and non-commercial sectors. Depicting the caricatures of the social, cultural and economic phenomenon and the recent surge of individual's depression, fatigue and pessimism, B-class emotional advertisements provide sympathetic and emotional alleviating ground for people that contributed to its rise.

The elderly people with advancing years have many problems such as the decline of the proprioceptive, visual & vestibular function and muscle weakness. Furthermore the decrease of the reflex which influences the balance ability in sudden change of the movement could cause the falls. The difficulty of the balance caused by the fear releated to the fall aggravates the Falls Efficacy and causes a lot of the disability of the independent activities of daily living. The purpose of this study was the effect of a Virtual Reality Program on Static Balance control and Fall efficacy of Elderly people. 14 elderly people(subjects) who were ≥65years of age partiripated in this study and they were divided into VR(Virtual Reality) group(n=7) and Control group (n=7). VR group took the general physical therapy & IREX and only the general physical therapy was carried out in the control group. VR group of intervention was carried out for 30min. total 8times. They were evaluated by BIO-Rescue, Fall Efficacy Scale before and after treatment. The Static Balance control and Fall efficacy were assessed by Bio-Rescue & Falls Efficacy Scale. The analysis of the resulf was assessed by Wilcoxon signed test & Mann-Whitney U test. The result showed that the static balance of VR group with the open eyes was improved in a static balance test and range of the movement was increased in limited of stability. And Falls Efficacy was also efficacious. IREX was effective to static balance control and Falls Efficacy of the elderly When we think about these effects, various treatments and objective assessments using VR program will be needed for the elderly

Objectives The aim of this study was to analyze the trends of researches on oriental medicine treatments for supraspinatus tendinopathy. Methods We used five databases for searching researches; Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, Research Information Sharing Service, PubMed, and China National Knowledge Infrastructure. Only randomized controlled trials suitable for the subject were selected. The methodological quality of included randomized controlled trials (RCTs) was assessed by the Cochrane risk of bias tool. Results Twenty randomized controlled trials were analyzed. There were 9 types of treatment interventions; acupuncture, acupotomy, pharmacopuncture, electroacupuncture, fire needling, warming needle, catgut-embedding therapy, herbal medicine, cupping. The most frequently used treatment intervention was acupuncture and acupotomy. There were 9 outcome measurements including visual analog scale (VAS), Constant-Murley Score (CMS), and range of motion. The most used measurement was VAS. As a result of meta-analysis, acupuncture was more effective than control group in VAS. Additionally, acupotomy was clinically significant compared to control groups in VAS and CMS. Conclusions In this review, we analyzed researches on effectiveness of oriental medicine for supraspinatus tendinopathy. A provisional conclusion can be produced that acupuncture and acupotomy showed beneficial effect to supraspinatus tendinopathy. Although there were some RCT studies, many of them had a high risk of bias, so it is hard to conclude that our study can include overall clinical status. Further well-designed trials are needed.

Objective: To objectively and subjectively assess and compare the characteristics of monoenergetic images [MEI (+)] and polyenergetic images (PEI) acquired by dual-energy CT (DECT) of patients with breast cancer. Materials and Methods: This retrospective study evaluated the images and data of 42 patients with breast cancer who had undergone dual-phase contrast-enhanced DECT from June to September 2019. One standard PEI, five MEI (+) in 10-kiloelectron volt (keV) intervals (range, 40-80 keV), iodine density (ID) maps, iodine overlay images, and Z effective (Z_eff) maps were reconstructed. The contrast-to-noise ratio (CNR) and the signal-to-noise ratio (SNR) were calculated. Multiple quantitative parameters of the malignant breast lesions were compared between the arterial and the venous phase images. Two readers independently assessed lesion conspicuity and performed a morphology analysis. Results: Low keV MEI (+) at 40-50 keV showed increased CNR and SNR_{breast lesion} compared with PEI, especially in the venous phase ([CNR: 40 keV, 20.10; 50 keV, 14.45; vs. PEI, 7.27; p < 0.001], [SNR_{breast lesion}: 40 keV, 21.01; 50 keV, 16.28; vs. PEI, 10.77; p < 0.001]). Multiple quantitative DECT parameters of malignant breast lesions were higher in the venous phase images than in the arterial phase images (p < 0.001). MEI (+) at 40 keV, ID, and Z_eff reconstructions yielded the highest Likert scores for lesion conspicuity. The conspicuity of the mass margin and the visual enhancement were significantly better in 40-keV MEI (+) than in the PEI (p = 0.022, p = 0.033, respectively). Conclusion: Compared with PEI, MEI (+) reconstructions at low keV in the venous phase acquired by DECT improved the objective and subjective assessment of lesion conspicuity in patients with malignant breast lesions. MEI (+) reconstruction acquired by DECT may be helpful for the preoperative evaluation of breast cancer.

Objectives This study aims to analyze clinical studies on subacromial-subdeltoid (SA-SD) bursitis and propose future directions for clinical research on SA-SD bursitis. Methods We searched eight databases to investigate research trends in Korean medicine treatments for SA-SD bursitis up to November 2023. A total of thirty-one studies were included in this analysis. Results Among the included studies, there were six case reports from Korea, fifteen case reports, and ten randomized controlled trials from abroad. Various interventions were uesd, including acupuncture, pharmacopuncture, manual therapy, electro-acupuncture, cupping, physiotherapy, acupotomy, warm-acupuncture, herbal medicine, and moxibustion. The evaluation tools used in these studies included the total effective rate, visual analogue scale, range of motion, and numeral rating scale. Conclusions This study provides an overview of the research trends in Korean medicine treatments for SA-SD bursitis. However, given the low quality and small sample sizes of the studies, the evidence supporting effect of Korean medicine treatments for SA-SD bursitis was insufficient. Further clinical trials and systematic reviews are required.

Objective: This study aimed to assess the technical feasibility, efficacy, and safety of the safe triangular working zone (STWZ) approach applied in percutaneous vertebroplasty (PV) for spinal metastases involving the posterior part of the vertebral body. Materials and Methods: We prospectively enrolled 87 patients who underwent PV for spinal metastasis involving the posterior part of the vertebral body, with or without the STWZ approach, from January 2019 to April 2022. Forty-nine patients (27 females and 22 males; mean age ± standard deviation [SD], 57.2 ± 11.6 years; age range, 31-76 years) were included in group A (with STWZ approach), accounting for 54 vertebrae. Thirty-eight patients (18 females and 20 males; 59.1 ± 10.9 years; 29-81 years) were included in group B (without STWZ approach), accounting for 57 vertebrae. Patient demographics, procedure-related variables, and pain relief as assessed using the visual analog scale (VAS) were collected at different time points. Tumor recurrence in the vertebrae after PV was analyzed using Kaplan-Meier curves. Results: The STWZ approach was successful from T1 to L5 without severe complications. Cement filling was satisfactory in 47/54 (87.0%) and 25/57 (43.9%) vertebrae in groups A and B, respectively (p < 0.001). Cement leakage was not significantly different between groups A and B (p = 1.000). Mean VAS score ± SD before and 1 week and 1, 3, 6, 9, and 12 months after PV were 7.6 ± 1.8, 4.2 ± 2.0, 2.7 ± 1.9, 1.9 ± 1.5, 1.7 ± 1.4, 1.7 ± 1.1, and 1.6 ± 1.3, respectively, in group A and 7.2 ± 1.7, 4.0 ± 1.3, 3.4 ± 1.6, 2.4 ± 1.2, 1.8 ± 1.0, 1.4 ± 0.5, and 1.7 ± 0.9, respectively, in group B. Kaplan-Meier analysis showed a lower tumor recurrence rate in group A than in group B (p = 0.001). Conclusion: The STWZ approach may represent a new, safe, alternative/auxiliary approach to target the posterior part of the vertebral body in the PV for spinal metastases.

Background: This study compares the outcomes of Latarjet-Patte procedures (LPs) performed for primary glenohumeral instability in the setting of critical bone loss (LP-BL) versus salvage surgery performed after a failed arthroscopic Bankart repair (LP-FB). Methods: LP's performed by senior author from 2017 to 2021 were separated into cohorts by LP indication. Data abstracted from electronic medical records included demographic information, preoperative clinical scores, radiological imaging, and complications. Postoperative clinical outcome scores collected after a 2-year minimum follow-up included: patient-reported outcomes measurement information system (PROMIS) upper extremity (UE), PROMIS pain interference, PROMIS pain intensity, American Shoulder and Elbow Surgeons (ASES), and visual analog scale pain scores. Results: A total of 47 patients (LP-BL: n=29, LP-FB: n=18) with a mean age of 29 years (range, 15-58 years) were included in this study. Both cohorts achieved good upper extremity functionality without significant differences as indicated by mean PROMIS UE (LP-BL: 52.6±10.0 vs. LP-FB: 54.6±7.6, P=0.442) and ASES score (LP-BL: 89.9±15.7 vs. LP-FB: 91.5±14.4, P=0.712). However, the LP-FB cohort reported lower levels of pain (LP-FB: 0.5±1.1 vs. LP-BL: 1.9±2.7, P=0.020) at their latest follow-up. There were no significant differences in complication rates including re-dislocation between cohorts (LP-BL: 2/29 [6.9%] vs. LP-FB: 2/18 [11.1%], P=0.629). Conclusions: When performed after failed Bankart repair, the LP results in similar postoperative functional outcomes and similar rates of complications and re-dislocations when compared to the primary indication of recurrent glenohumeral instability in the setting of critical bone loss.

The purpose of this study was to evaluate the value of passive caudal gliding mobilization of the glenohumeral joint on the range of motion (ROM) of active and passive abduction; to evaluate the value of pain relief through visual analogue scale (VAS); to evaluate the correlation between improvement of shoulder abduction and intra-articular movement measured by fluoroscopy in frozen shoulder patients. The subjects consisted of twenty-one patients with clinically diagnosed frozen shoulder (11 males, 10 females) between 40 and 63 years of age (mean age : 52.7 years). The traction and caudal gliding mobilization based on the convex-concave rule in the resting position and at end range of abduction was peformed for 15 minutes per day and was repeated 10 times during a 2 week period. The ROM of abduction was measured by goniometer and pain was measured by VAS. The intra-articular movement was measured by fluoroscope, Neurostar Plus TOP (Siemens, Germany). ROM measurements of each patient was acquired at pre-treatment, immediate post-treatment and 2 week post-treatment. Statistical analysis was performed using SPSS 10.0 for Windows software and data was analyzed using the paired-test and the pearson correlation. The results of this study are as follows: 1. There was a significant decrease of VAS between pre-treatment data and 2 week post-treatment data (P<.05) but no significant difference between pre-treatment and immediate post-treatment data (P>.05). 2. There was a significant increase in ROM of active and passive abduction in the pre-treatment data, immediate post-treatment data, and in 2 week post-treatment data (P<.05). 3. With regard to results of the joint play test, there was a significant difference in the grade of traction between pre-treatment data and immediate post-treatment data and between pre-treatment data and 2 week post-treatment data (P<.05). There was no significant difference between immediate post-treatment data and 2 week post-treatment data (P>.05). 4. With regard to results of the joint play test, there was a significant difference in the grade of caudal gliding between pre-treatment data and immediate post-treatment data and between pre-treatment data and 2 week post-treatment data (P<.05). There was no significant difference between immediate post-treatment data and 2 week post-treatment data (P>.05), 5. With regard to the results of fluoroscopic findings, there was a significant change of the glenohumeral joint space between pre-treatment data and immediate post-treatment data and between immediate post-treatment data and 2 week post-treatment data (P<.05). There was no significant change of the glenohumeral joint space between immediate post-treatment data and 2 week post-treatment data (P>.05). 6. With regard to the results of fluoroscopic findings, there was a significant change of acromiohumeral joint space between the three data (pre-treatment data, immediate post-treatment data, 2 week post-treatment data) (P<.05). 7. Mobility grade by joint play test was significantly increased and was correlated to improved ROM of active and passive abduction (P<.05). In this study of frozen shoulder, passive caudal gliding techniques of the glenohumeral joint results in statistically significant changes in active and passive abduction as well as in VAS. There is also a significant correlation between joint play test and ROM of abduction.

In the present paper I described the results of the observations made on the visual characteristics such as the annual ring width and summerwood percentage of Pinus koraiensis Sieb. et Zucc. grown at out university forest. The results of the study are as follows: Characteristics of annual ring width and summerwood percentage 1. The range of dispersion of annual ring width and summerwood percentage are respectively 0.5-6.5mm and 5-50% on the normal wood and its arithmetic mean values are each 3.0mm and 24% on all sample trees. 2. The values of annual ring width of heart wood are larger than that of sapwood but on the contrary the values of summerwood percentage of heartwood are smaller than that of sapwood. On the other hand variations of these values are distingushed on the heartwood. 3. The values of annual ring width due to the parts of stem with crown. with clear length and at bottom showed that the largest values are given at the parts of stem with crown. But on the contrary the summerwood percentage values are largest at the parts of stem at bottom on all sample trees. 4. The values of annual ring width and summerwood percentage depending on the stand sides are not obvious. Horizontal and vertical variations of annual ring width and summerwood percentage 5. It was recognized that horizontal (radial direction) variations of annual ring width and summerwood percentage indicated two different patterns (the region of large fluctuation and that of small fluctuation) in a tree stem. These boundaries are seemed to appear at the parts of 12-15 annual rings from pith. 6. According to the increase of height in tree the values of annual ring width increase but the values of summerwood percentage gradually decrease. 7. But vertical variations of annual ring width and summerwood percentage on the sapwood are divided into two different parts (region of increased or decreased upwards and that of remained constant in successive height) in a tree stem and these limits are seemed to appear at the 7m of height in trees. Relations between annual ring width and summerwood percentage 8. The modes of summerwood percentage related with annual ring width are seemed to appear almost in the definite range (10-25%). 9. The relations between annual ring width and summerwood percentage show a highly negatine correlation on all sample trees.
