Objectives: Frozen shoulder (FS) is one of the most challenging shoulder disorders for patients and clinicians. Its symptoms mainly include any combination of stiffness, nocturnal pain, and limitation of active and passive glenohumeral joint movement. Conventional treatment options for FS are physical therapy, nonsteroidal anti-inflammatory drugs, injection therapy, and arthroscopic capsular release, but adverse and limited effects continue to present problems. As a result, pharmacoacupuncture (PA) is getting attention as an alternative therapy for patients with FS. PA is a new form of acupuncture treatment in traditional Korean medicine (TKM) that is mainly used for musculoskeletal diseases. It has similarity and specificity compared to corticosteroid injection and hydrodilatation, making it a potential alternative injection therapy for FS. However, no systematic reviews investigating the utilization of PA for FS have been published. Therefore, this review aims to standardize the clinical use of PA for FS and validate its therapeutic effect. Methods: The protocol was registered in Prospero (CRD42023445708) on 18 July 2023. Until Aug. 31, 2023, seven electronic databases will be searched for randomized controlled trials of PA for FS. Authors will be contacted, and manual searches will also be performed. Two reviewers will independently screen and collect data from retrieved articles according to predefined criteria. The primary outcome will be pain intensity, and secondary outcomes will be effective rate, Constant-Murley Score, Shoulder Pain and Disability Index, range of motion, quality of life, and adverse events. Bias and quality of the included trials will be assessed using the Cochrane handbook's risk-of-bias tool for randomized trials. Meta analyses will be conducted using Review Manager V.5.3 software. GRADE will be used to evaluate the level of evidence for each outcome. Results: This systematic review and meta-analysis will be conducted following PRISMA statement. The results will be published in a peer-reviewed journal. Conclusion: This review will provide scientific evidence to support health insurance policy as well as the standardization of PA in clinical practice.
The payload BioCabinet of CAS500-3 is designed for 3D stem cell differentiation, culture, and analysis utilizing bio 3D printing techniques in space. The 3D printing technique was initially developed for orbital use; however, it lacks separate validation for extreme launch vibration environments, necessitating a design that mitigates the launch load on the payload. This paper proposes a passive vibration isolator with a low-stiffness elastic support structure and high damping characteristics to reduce the launch loads affecting the BioCabinet. We explore the high-damping characteristics through the superelastic effects of SMA (Shape Memory Alloys) and a multi-layered structure incorporating viscoelastic tape. The effectiveness of the proposed vibration isolation system was confirmed via launch vibration tests on a qualification model.
Purpose : The prevalence of childhood obesity has doubled over the last 30 years. Obesity-associated sequelae in the vasculature begins in the early stages of life. The purpose of this study was to investigate how pulse wave velocity (PWV) and ankle brachial index (ABI) change with height, weight and body mass index (BMI) in obese adolescents. Methods : Seventy-nine obese adolescents (group 1: $85th{\leq}BMI<95th$ percentile, n=40; group 2 ($BMI{\geq}95th$ percentile, n=39) were included. The control group(group 3) included 99 healthy adolescents. Brachial- ankle (ba) PWV and ABI were estimated with blood pressure from four extremities. Heart rate (HR), and pre-ejection period/ejection time (PEP/ET) were also estimated. BMI was calculated from individual height and weight. Linear regression analysis was performed to evaluate the correlations between BMI and PWV. Results : Blood pressure and baPWV were significantly higher in group 2, compared to either group 1 or group 3. However, there was no significant difference in ABI, HR and PEP/ET between the groups. PWV showed linear correlation with both BMI and body weight. Conclusion : Obesity was associated with higher arterial stiffness in adolescents, which was demonstrated by an increase in PWV. There was no significant correlation between obesity and ABI.

Objectives : This study was designed to compare the effects on Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), 36-ltems Short-Form Health Survey(SF-36), Visual Analog Scale(VAS) and Nine Point Scale between 'Intramuscular Bee Venom Herbal Acupuncture' and 'Intracutaneous Bee Venom Herbal Acupuncture' in knee osteoarthritis patients for 4weeks. Methods : All the voluntary subject were diagnosed as knee osteoarthritis. Patients were randomly assigned either to two groups : Intramuscular bee venom herbal acupuncture treatment group(IM-BV group) or Intracutaneous bee venom herbal acupuncture treatment group(IC-BV group). The IM-BV group received bee venom herbal acupuncture intramuscularly on muscles closest to the pathologic site on ultrasonography. The IC-BV group received bee venom herbal acupuncture intracutaneously on $LE_{110}$, $LE_{201}$, $ST_{35}$, $ST_{36}$ and $LR_8$. Bee venom herbal acupuncture was applied twice a week for 4 weeks by an oriental medical doctor at Kyung-hee Oriental Medical Hospital. Both groups were checked of pathologic site by ultrasonography before treatment and follow up after four-week treatment. The patients were assessed by KWOMAC and SF-36 before and after four-week treatment. The changes in patients' pain was measured by VAS before treatment and after one-, two-, three- and four-week treatment. The patients' overall treatment outcome assesment was measured by Nine Point Scale after four-week treatment. Results : The results were as follows ; 1. The IM-BV group showed significant improvement on total, pain, stiffness and physical function in KWOMAC, and the IC-BV group showed significant improvement on total and physical function in KWOMAC after 4weeks compared to the pre-treatment. In KWOMAC, the IM-BV group showed more improvement on average compared to the IC-BV group, but there were no significant difference between two groups. 2. The IM-BV group showed significant improvement on VAS after one-week treatment. The IC-BV group showed significant improvement on VAS after two-week treatment. But there were no significant difference between two groups. 3. The IM-BV group showed significant improvement on physical functioning(PF) and bodily pain(BP) in SF-36, and the IC-BV group showed significant improvement on vitality(VT) and bodily pain(BP) in SF-36 after 4weeks compared to the pre-treatment. But there were no significant difference between two groups. 4. 88.2% of IM-BV group and 93.3% of IC-BV group graded their improvement as 'Fair' or better on Nine Point Scale. But there were no significant difference between two groups. Conclusions : This study suggests that in the treatment of knee osteoarthtitis patients, effects of 'Intramuscular Bee Venom Herbal Acupuncture' were not different from 'Intracutaneous Bee Venom Herbal Acupuncture' statistically. But both treatment showed effects on pain and physical function in knee osteoarthtitis patients.
As a basic research material to make more efficient healthcare and health promotion for dental hygienists, this study intends to determine which factors may affect their awareness of occupational diseases. For this sake, this study attempted to investigate into a variety of literatures and data, and applied a questionnaire survey to 160 dental hygienists for about 5 months(from June to October 2003), who were all employed in domestic dental clinics or offices. As a result of analysis, this study can be concluded as follows: (1) The result of analyzing how dental hygienists recognized their occupational diseases showed that 'stiffness in muscle, neck or shoulder due to intensive use of specific physical regions' and 'stress resulting from the attributes of each task' reached the highest awareness(90.6%) of all, which was followed by 'lower eyesight due to detailed or even sophisticated tasks for many hours(65%)' and 'symptoms of ruptured disk due to standing tasks as dental hygienists do for many hours(62.5%).' (2) The result of analyzing how dental hygienists recognize their occupational diseases showed that their awareness averaged 7.28 points out of 14 points, which implies that their awareness of occupational diseases is not very high. Meanwhile, the result of examining how they recognize detrimental or harmful properties of given materials against human body showed that a majority of total respondents(74.4%) regarded given materials as detrimental to human body. (3) The result of examining how dental hygienists recognize their occupational diseases showed that a majority of total respondents(91.9%) identified their own occupational diseases. Many of total respondents(41.9%) pointed out that environmental improvement around workshop in each clinic or office should be foremost prerequisite to health and welfare for dental hygienists. Next, 34.4% of total respondents pointed out the necessity to perform in-house health diagnosis and examination on a regular basis, and 13.1% of total respondents thought it necessary to carry on healthcare education into harmful properties in the aspect of dental materiology, respectively.
Purpose: The purpose of this study is to introduce the double bundle posterior cruciate ligament(PCL) reconstruction using Achilles allograft by the tibial inlay method and evaluate the clinical results of 11 cases who had PCL reconstruction using this method and were followed for more than 2 years after surgery. Materials and Methods: Our series consists of 11 cases of PCL reconstruction due to chronic posterior instability of knee and acute PCL rupture. The clinical results were assessed using the IKDC(International Knee Documentation Committee) scoring system, posterior stress radiographs and the maximum posterior displacement using a KT-1000TM arthrometer. Results: The average preoperative posterior displacement in 90 degree flexion stress radiograph was measured 13.4 mm and in 10 degree flexion the average posterior displacement using the KT-1000TM arthrometer was measured 11.4 mm. Postoperatively the 13.4 mm reduced to 4.4 mm and the 11.4 mm reduced to 3.9 mm. According to IKDC scoring system, 9 cases(81.8%) were satisfied. One case showed limitation of flexion with mild stiffness in the knee and another one case was not improved the posterior instability sufficiently and no complication of allograft was noticed. Conclusion: The double bundle PCL reconstruction using Achilles allograft by the tibial inlay method is a useful method for acute PCL rupture and chronic posterior instability of the knee including failed PCL reconstruction, because it will also make the posterior stability in the extension and 90 degree flexion position, and avoid the grafted tendon abrasion by acute turn of tibial tunnel.

The transforming growth $factor-{\beta}$ ($TGF-{\beta}$) is a multifunctional cytokine modulating the onset and course of autoimmune disease as shown in experimental models. In synovial inflammation, there is a potential role for $TGF-{\beta}$ in repairment, the inhibition of cartilage and bone destruction, and the down-regulation of immune response. The biologic effects of $TGF-{\beta}$ depend on the cell type, the isoform and the availability of active $TGF-{\beta}$. We investigated $TGF-{\beta}$ expression in patients with rheumatoid arthritis (RA) and compared to those of osteoarthritis (OA). And we determined a correlation between $TGF-{\beta}1$ and $TGF-{\beta}2$, and also the relationships between each $TGF-{\beta}$ isoform and the parameters for disease activity of RA. Methods: The study population consisted of 20 patients with RA and 20 patients with OA. The commercial ELISA kit was used to study $TGF-{\beta}1$ and $TGF-{\beta}2$ levels in peripheral blood (PB) and synovial fluids (SF). Results: 1) While PB $TGF-{\beta}1$ level was of no difference between RA and OA patient groups, SF $TGF-{\beta}1$ level was higher in RA group than OA group. Similarly, PB $TGF-{\beta}2$ levels of RA and OA groups was not different, but SF $TGF-{\beta}2$ levels was higher in RA group than OA group. 2) In patients with RA, the $TGF-{\beta}1$ levels were higher than $TGF-{\beta}2$ in both the PB and SF, while in patients with OA, there showed higher readings for $TGF-{\beta}1$ than $TGF-{\beta}2$ in SF but no difference between $TGF-{\beta}1$ and $TGF-{\beta}2$ levels in PB. 3) In patients with RA, there were no correlations between PB $TGF-{\beta}1$ and PB $TGF-{\beta}2$ levels, nor between SF $TGF-{\beta}1$ and SF $TGF-{\beta}2$ levels. At the same way, there was no correlation between PB $TGF-{\beta}1$ and SF $TGF-{\beta}1$ levels, nor between each levels of $TGF-{\beta}2$ in patients with RA. 4) There was also no correlation between each $TGF-{\beta}$ isoform and the parameters for disease activity such as ESR, CRP, tender joint count, swollen joint count, rheumatoid factor, and the duration of morning stiffness except between in PB $TGF-{\beta}1$ and disease duration of RA (r=0.637, p<0.01). Conclusion: Each $TGF-{\beta}$ isoforms were higher in synovial fluid of patients with RA than that of patients with OA. The data from the RA patients demonstrated different patterns of expressions of the isoforms depending on which compartment (PB or SF) was investigated. The quantification of different $TGF-{\beta}$ isoform is thought to be important when $TGF-{\beta}$ is measured under disease conditions of RA.
Purpose : Extensive defect of oral and maxillofacial area is usually reconstructed with composite flap including skin paddle. However, if the defects are lined with only skin components, the mucosa's role in mastication and texture are not restored. Furthermore, stiffness and hair-growing prevent denture rehabilitation and good oral hygiene. This study was performed to overcome the disadvantages of composite soft tissue flaps including the skin and to make a model for myo-mucosal flaps. Materials and methods : Buccal mucosa sized $0.5\times1.0\;cm^2$ from New Zealand rabbit (around 1.5kg) was harvested and cultivated by the modification of Rheinwald and Green's keratinocyte culture method. Cultured mucosa was grafted on the fascia of latismus dorsi as form of mucosal sheet. After 7, 10, 14 days, the myomucosal flap was excised and evaluated under light microscope with H & E and immunohistochemical staining. As control group, harvested buccal mucosa from rabbit was transplanted to gracilis muscle(n=6). Results : From 7 days after prelamination, the basal layer of the grafted mucosa resembled that of normal mucosa. As control group, transplanted mucosa had original shape but there's slight inflammatory reaction. Prelaminated mucosa has 19.8$\pm$4.59 cell layers and some samples have more than 20 layers. The expression rate of PCNA was relatively strong (42.9%$\pm$14.1) at the basal layer of grafted mucosa and the laminin was found at the basal layer. On the contrary, prelaminated mucosa at 10 days showed moderate expression rate of PCNA(32.4%$\pm$4.62). We found the mucosal layer was somehow disappeared and there is strong inflammatory reaction. After 14 days prelamination, the grafted oral keratinocytes were almost disappeared and expression of PCNA was not observed. Conclusion : We can make 75 fold large mucosal($3850mm^2$) sheet from small samples of mucosa $(50mm^2)$. Epithelial sheet that grafted on the fascia of muscle underwent differentiation and proliferation. But after 10, 14 days, there was strong inflammatory reaction and the grafted mucosa was destroyed from surface layer. In rabbit model, transfer of fascio-mucosal flap should be done from 7 to 10 days after prelamination.

The purpose of this study was to find the rational method to analyze golf swing with specific property of club shaft. Three subjects were filmed by two high speed digital cameras with 500 fps. The phase analyzed was downswing of each subject. The three-dimensional coordinates of the anatomical landmarks were obtained with motion analysis system Kwon3d 3.0 version and smoothed by lowpass digital filter with cutoff frequency 6Hz. From these data, kinematic and kinetic variables were calculated using Matlab(ver 5.0) The variables for this study were angular velocity and accelerations, which were calculated and following conclusions have been made : 1) Golf swing time of stiff club is faster than that of regular club. 2) In shoulder joint motion of swing with the stiff club, x-stiff showed mort rapid negative acceleration than that of regular club. 3) In regular club, the velocity of club head would be more effective velocity, which was increasing, than those of other clubs before impact. 4) In wrist joint motion of swing with stiff club, x-stiff club showed faster than regular club in the downswing and impact more rapid negative acceleration.
From several researches, recently, it was found that using hollowed precast concrete (HPC) column made more compact concrete casting in joint region possible than using normal solid PC (Precast concrete) column. Therefore, the rigidity of joints can be improved like those of monolithic reinforced concrete (RC). After filling the hollow with grout concrete, however, it is expected that the HPC column behaviors like composite structure since PC element and grout concrete have different materials as well as there is a contact surface between two elements. These may affect the structural behavior and strength of the composite column. A compressive strength test was performed for the HPC column with parameter of hollow ratio for the case with and without grout in the hollow and the result is presented in this paper. The hollow ratios in the test are 35, 50 and 59% of whole section of column. Concentrated axial force was applied to top of the specimens supported as pin connection for both ends. In addition, finite element (FE) analysis was performed to simulate the failure behavior of HPC column for axial compression. As a result, it was found that the hollow ratio did not affect the initial stiffness of HPC filled with grout regardless of the strength difference of HPC and grout. However the strength was increased inversely corresponding to the hollow ratio. The structural capacity of HPC without grout closely related to the hollow size. Especially, the local collapse governs the overall failure when the thickness of HPC is too thin. Based on these effect, a suitable equation was suggested for calculation of the compressive strength of HPC column with or without grout. FE analysis considering the contact surface between HPC and grout produced a good result matched to the test result.
