Background: Scapulohumeral periarthritis causes pain and stiffness, and limits movement but it is a treatable condition. This was a clinical study of acupotomy treatment for scapulohumeral periarthritis. Methods: There were 80 patients randomly assigned to the traditional Chinese Medicine group (acupotomy) and the Western medicine group (naproxen), with 40 cases in each group. All patients had adjunct physiotherapy exercises for 14 days. Patients received acupotomy treatment 3 times for 14 days (Day 0, 7 and 14) or naproxen (0.22 g capsule; a non-steroidal anti-inflammatory drug) 3 times a day, for 14 days. The visual analogue scale (VAS) scores, range of motion (ROM) values, and the Melle scale, together with the therapeutic standard of diseases and syndromes in traditional Chinese Medicine were used for diagnosis and evaluation. Results: There were significant differences in the VAS scores, ROM, Melle scores, cure rate and total effective rate in the group which took naproxen and the acupotomy group, before and after treatment (p < 0.01). There were significant differences in the changes in VAS, ROM and Melle scores between the 2 groups (p < 0.01), and the acupotomy group was better than the naproxen group. Conclusion: Traditional Chinese Medicine and Western medicine can improve functional activity and reduce the level of pain experienced by patients suffering from scapulohumeral periarthritis. However, improvement of functional activity of the shoulder joint following acupotomy treatment was more obvious than the use of a non-steroidal anti-inflammatory drug, and the cure rate, and total effective rate of acupotomy was better.

Background: Associations between ABO blood groups and risk of several malignancies have been reported, although there are limited data regarding hepatocellular carcinoma (HCC). The aim of this study was to investigate any possible association between the ABO genotype, especially blood group A, and HCC risk in Koreans. Materials and Methods: We conducted a case-control study of 1,538 patients with newly diagnosed HCC at Chonnam National University Hwasun Hospital and 1,305 randomly selected members of the general population. The ABO genotype was determined by multicolor real-time polymerase chain reaction (PCR) using displacing probes. Adjusted odds ratios (aORs) and their 95% confidence intervals (CIs) were calculated using logistic regression models with adjustment for gender, age, smoking, alcohol drinking, and hepatitis B and C status. Results: The risk of HCC in genotype AA was significantly higher than in OO (aOR=1.773, 95% CI=1.161-2.705). The risk in blood group A was also higher than in blood group O (aOR=1.448, 95% CI=1.005 1.897). No significant difference was found for the AA, BO, BB, and AB genotypes, or blood group B and AB. Conclusions: Blood group A and genotype AA showed the highest risks of HCC in a Korean population. No significant difference was found for the AO, BO, BB, and AB genotypes, or blood group B and AB.

Background: Shammah is a traditional form of snuff dipping tobacco (a smokeless tobacco form) that is commonly used in Yemen. Oral mucosal changes due to the use of shammah can usually be observed in the mucosal surfaces that the product touches. The aim of this study was to determine the association between shammah use and oral leukoplakia-like lesions. Other associated factors were also determined. Materials and Methods: A cross sectional study was conducted on 346 randomly selected adult males. Multi-stage random sampling was used to select the study location. After completing the structured questionnaire interviews, all the participants underwent clinical exanimation for screening of oral leukoplakia-like lesions Clinical features of oral leukoplakia-like lesion were characterized based on the grades of $Ax{\acute{e}}ll$ et al (1976). Univariable logistic regression and multivariable logistic regression were used to assess the potential associated factors. Results: Out of 346 male participants aged 18 years and older, 68 (19.7%) reported being current shammah users. The multivariable analysis revealed that age, non-formal or primary level of education, former shammah user, current shammah user, and frequency of shammah use per day were statistically associated with the presence of oral leukoplakia-like lesions [Adjusted odds ratio (AOR) = 1.03; 95% confidence interval (CI) : 1.01, 1.06; P=0.006], (AOR=8.65; 95% CI: 2.81, 26.57; P=0.001), (AOR=3.65; 95% CI: 1.40, 9.50; P=0.008), (AOR=12.99; 95% CI: 6.34, 26.59; P=0.001), and (AOR=1.17; 95% CI: 1.02, 1.36; P=0.026), respectively. Conclusions: The results revealed oral leukoplakia-like lesions to be significantly associated with shammah use. Therefore, it is important to develop comprehensive shammah prevention programs in Yemen.

Silicide layer structures, agglomeration of silicide layers, and dopant redistributions for the Co/Ti bilayer sputter-deposited on the P-doped polycrystalline Si substrate and subjected to rapid thermal annealing were investigated and compared with those on the single Si substrate. The $CoSi_2$ phase transition temperature is higher and agglomeration of the silicide layer occurs more severely for the Co/Ti bilayer on the doped polycrystalline Si substrate than on the single Si substrate. Also, dopant loss by outdiffusion is much more significant on the doped polycrystalline Si substrate than on the single Si substrate. All of these differences are attributed to the grain boundary diffusion and heavier doping concentration in the polycrystalline Si. The layer structure after silicidation annealing of Co/ Tildoped - polycrystalline Si is polycrystalline CoSi,/polycrystalline Si, while that of Co/TiI( 100) Si is Co- Ti- Si/epi- CoSi,/(lOO) Si.

In this paper, age exploration of ${\bigcirc}{\bigcirc}$ anti-ship missiles which were deployed on RoKN ships were analysed using parametric estimation method. Additionally, Life distribution and failure pattern of ${\bigcirc}{\bigcirc}$ anti-ship missile were analysed by using field data such as collected inspection, fail, maintenance record for 6 years. Storage failure and MTBF of missile and components were analysed by using reliability analysis s/w Weibull++ v7. The results were compared with maintenance policy including periodic inspection and MTBF which were analysed during development phase. Finally, the suggested methodology using field data analysis of oo anti-ship missile will be applied on re-estabilishment of maintenance policy of ${\bigcirc}{\bigcirc}$ anti-ship missile for TLCSM(Total Life Cost System Management) effectively.

One of the computer application fields which started showing noticeable new growth trends in recent years is the real time communication distributed computing application field. Object-oriented(OO) real time(RT) distributed computing is a form of real-time distributed computing realized with a distributed computer system structured in the form of an object network. In this paper, we describes the application environment as the patient monitor telemedicine system with TMO structure. Vital sign information web viewer systems is also the standard protocol for medical image and transfer. In order to embrace new technologies as telemedicine service, it is important to develope the standard protocol between different systems in the hospital, as well as the communication with external hospital systems. We implemented integration patient monitor telemedicine system between vital sign web viewer systems and hospital information systems.

In this paper, we propose a QoS-aware efficient bandwidth re-provisioning scheme in a next generation wireless packet transport network. At the transport network layer, it classifies the traffic of the radio network layer into a real time class and a non-real time class. Using an auto-regressive time-series model and a given packet loss probability, our scheme predicts the needed bandwidth of the non-real time class at every re-provisioning interval. Our scheme increases the system capacity by releasing the unutilized bandwidth of the non-real time traffic class for the real-time traffic class while insuring a controllable upper bound on the packet loss probability of a non-real time traffic class. Through empirical evaluations using the real Internet traffic traces, our scheme is validated that it can increase the bandwidth efficiency while guaranteeing the quality of service requirements of the non-real time traffic class.

This paper introduced an alternative method called USCP (Unpenetrated Sand Compaction Pile). In USCP, the toe of the sand pile does not reach to the lower supporting layer. Hence it is possible to reduce the amount of sand required. However, the degree of improvement could not be the same as SCP. Effective soil improvement, nevertheless, might be possible by combining both methods. In this paper, an improved method that cross over both SCP and USCP was discussed. And in order to verify applicability to a clay layer, consolidation behaviors with different conditions were analyzed and compared using FEM(Finite Element Method) based on the elasto-viscosity theory. From the results, it is concluded for the characteristic of settlement of USCP that the lower degree of replacement and the smaller ratio of penetration($H_d/H$), the larger is the settlement of the lower part of the clay layer comparing to the layer with no improvement. It is also concluded that the ratios of allotment of stress (m) calculated from the final settlements with 30% of degree of replacement are $1.8{\sim}3.3$ for $H_d/H=lOO%,\;1.8{\sim}4.0\;for\;H_d/H=75%,\;and\;1.8{\sim}3.8\;for\;H_d/H=50%$. Besides, the ratio of allotment of stress decreased as the degree of replacement decreased.

In this paper, the study for the manufacture of the integrated composite wing is performed. The wing has a pivoting structure and high aspect ratio to increase lift drag ratio. The wing is designed with carbon fiber composite because the wing needs to be light and have sufficient strength and stiffness to satisfy structural design requirements. The number of structural members is decreased by part integration to reduce manufacturing cost and the wing is manufactured with the integrated molding process by an autoclave. The material properties are identified by the coupon tests and the structural strength and stiffness are verified through the component tests.
