For sharing XML data by many users, a way of concurrency and access control is required for isolating update actions such as inserting and deleting subtrees. Exisiting locking mechanisms as 2PL or MGL suffer low concurrency when applied to tree structures. In this paper, list data subtrees model is proposed based on the semantics expressed in DTD. In this model, tree updating actions such as inserting and deleting subtrees are considered only for the repetitive parts of XML trees. The proposed model guarantees that the result XML tree after applying a tree updating action is always valid, even when multiple users access the tree at the same time. Also, a new locking mechanism called list lock-ing protocol is proposed. The new locking protocol is expected to show better accessility with less number of locking objects compared to the Helmer's OO2PL model. Since update actions on a shared XML tree usually applied to the repetitive parts of the tree, the proposed model is expected to provide a useful way for efficient data sharing when combined with previous locking methods on terminal node data.

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.

To investigate the effect of a shaded apodizer on the read-out signal in an optical disc system, we consider the is apodizer in which the amplitude transmittance decreases gradually from the center of pupil toward its edge and the iH apodizer in which the amplitude transmittance increases gradually from the center of pupil toward its edge, using the scalar diffraction theory. We also consider the bump shapes which are a cylindric, a semi-conic, and a conic bump, and bump height which is given by $\lambda/4$ and occurs to the phase change $(\pi)$). The read-out signal of is apodizer increases from S = 0 upto maximum value, and then decreases for increasingly larger values of bOo While the iH apodizer has two maximum values. When an optical disc system has a spherical aberration $(W_{40}=0.5\lambda)$, the maximum read-OUt signal of is apodizer is higher than that of iv apodizer which has no apodizer.odizer.

The web is shifting from being a medium in which information is transmitted and consumed, into being a platform in which contents are created, shared, repurposed. Web 2.0 applications are those that make the most of the intrinsic advantages of that platform. This thesis proposed a learning system based on web 2.0 for promoting statistics literacy. For this, I proposed students to create UCC(User Created Contents) data to learn principle of statistics and practical use of statistical data. To examine educational effectiveness of this study, an experimental study was conducted through the education content and method to the subject of one class in the first-grade of university located in OO city. As a result, the student understanded basic principle on statistics and perceived importance of statistics literacy and presented positive responses to statistics. In conclusion, it is confirmed that it is possible to provide effective education for students if the statistics literacy is proposed to proper education method.

Background: Tobacco use among youth is a major public health problem. Youth outside of formal school settings are often understudied but may be at increased risk. Materials and Methods: A descriptive cross-sectional study was carried out among 326 young people aged 15-24 years in four randomly selected motor parks in Lagos state. Interviewer-administered questionnaires were used to collect data. Results: The mean age of the respondents was $21.0{\pm}2.3yrs$. Many 252 (77.3%) dropped out before the end of the third year of secondary schooling. The majority were aware that active (78.2%), and passive smoking (77.3%) are harmful to health. Nearly two-thirds of the respondents disagreed with an outright ban of cigarettes (63.2%) and restriction of cigarette sales to persons below 18 years (67.9%) while 254 (66.8%) supported a ban on tobacco smoking in enclosed public places. One hundred and fifty (46.0%) respondents had experimented with smoking of which 106 (32.5%) had progressed to become current smokers. Half of the current smokers, 54 (50.9%), felt the need for a cigarette first thing in the morning. A multivariate analysis for smoking initiation, showed that for every increasing year of age, respondents were 1.08 times more likely to have initiated cigarette smoking; males and respondents who lived alone or with peers were 2.34 times and 1.77 times more likely to have initiated smoking respectively; those who consume alcohol and marijuana were 7.27 and 1.89 times respectively more likely to have initiated smoking while those who consumed alcohol were 6.17 times more likely to be current smokers.

Purpose: Intraoperative peritoneal washing cytology (PWC) is used to determine treatment strategies for gastric cancer with suspected serosal invasion. However, a standard staining method for intraoperative PWC remains to be established. We evaluated the feasibility of a rapid and simple staining method using Shorr's stain for intraoperative PWC in advanced gastric cancer. Materials and Methods: Between November 2012 and December 2014, 77 patients with clinical T3 or higher gastric cancer were enrolled. The sensitivity, specificity, and concordance between the Shorr staining method and conventional Papanicolaou (Pap) staining with carcinoembryonic antigen (CEA) immunohistochemistry (IHC) were analyzed. Results: Intraoperative PWC was performed laparoscopically in 69 patients (89.6%). The average time of the procedure was 8.3 minutes, and the average amount of aspirated fluids was 83.3 mL. The average time for Shorr staining and pathologic review was 21.0 minutes. Of the 77 patients, 16 (20.7%) had positive cytology and 7 (9.1%) showed atypical findings; sensitivity and specificity were 73.6% and 98.2% for the Shorr method, and 78.9% and 98.2% for the Pap method with CEA IHC, respectively. Concordance of diagnosis between the 2 methods was observed in 90.9% of cases (weighted ${\kappa}$ statistic=0.875) and most disagreements in diagnoses occurred in atypical findings (6/7). In overall survival, there was no significant difference in C-index between the 2 methods (0.459 in Shorr method vs. 0.458 in Pap with CEA IHC method, P=0.987). Conclusions: Shorr staining could be a rapid and reliable method for intraoperative PWC in advanced gastric cancer.

The purpose of this study is to grasp the relationships between workplace spirituality, job turnover intentions, and job satisfaction in supporters for the disabled. The study was conducted with 134 OO supporters for the disabled. As an analysis method, SPSS software was used to perform frequency analysis, reliability analysis, correlation analysis, and multiple regression analysis of causal relationships between variables. The results of the study first found that vocational consciousness, a sub-factor of workplace spirituality in supporters for the disabled, had a significant negative (-) effect on turnover intentions. Second, as a result of examining the effects of workplace spirituality on job satisfaction in supporters for the disabled, other sub-factors of workplace spirituality (vocational consciousness and community consciousness) were found to have a positive (+) effect on job satisfaction. This means that a higher vocational consciousness of workplace spirituality perceived by supporters for the disabled lessens turnover intentions. The implications of this study are considered to be basic data for the development of capacity-building programs to prepare measures to reduce the turnover intentions in supporters for the disabled.

Purpose - This paper addresses the concepts of FDI-Trade-Growth nexus in Myanmar's economy and empirically investigates the interrelationships of trade, investment and economic growth to reveal the growth model of Myanmar's economy. Additionally, this paper also addresses the cooperative strategies between Myanmar and South Korea through a case study related to South Korea's economic growth. Design/methodology - Our empirical model considers the interrelationship among FDI, trade, growth, labor force and inflation in Myanmar. This study employs ARDL (Autoregressive Distributed Lag) to conduct an analysis of the FDI-Trade-Growth relationships using the time series data from 1970 to 2016 and a conducted case study of South Korea provided for practical implication on cooperative strategies between Myanmar and Korea. Findings - Export equation was chosen through the diagnostic tests. Our main findings can be summarized as follows: Export in Myanmar is positively influenced by labor force, FDI, capital formation and negatively impacted by import and instable inflation rate in the long run. In the short run, GDP and import positively influence export. The Granger causality test proves that Myanmar is an FDI/labor force-led Growth economy, where FDI and labor force are main drivers of export followed by GDP in Myanmar. The case study of South Korea provided that Korea's tax and credit system for promoting export-led FDI industries and cooperative units for joint ventures between Korea and Myanmar in export-led FDI industries are recommended. Originality/value - No study has yet to be conducted on the interrelationships of macroeconomic factors from the perspectives of FDI-Trade-Growth Nexus in Myanmar under the assumption of labor force and inflation rate as fundamental conditions. The current study also covered a relatively longer period of time series data from 1970 to 2016. This paper also conducts a case study of South Korea's experience in order to evaluate the findings and provide better policy implications.

Purpose - Brand equity has emerged as an indispensable marketing tool for firms engaging their business in developing nations. This study proposes that the country of origin image and advertising will affect the Korean brand equity formation, which leads to repurchase intention of Korean brands. In the study, attitude factors are applied in brand equity theory to predict repurchase intention of Korean brands. Cognitive brand equity, such as brand awareness, brand association, brand image and attitudinal brand equity, such as perceived quality and brand loyalty are considered with regards to their attitude towards the Korean brand. Design/methodology - A total of 178 Myanmar consumers out of 200 participants who have used Korean brands answered the survey and data were analyzed through SmartPLS 3.3.2 version. PLS-SEM is considered a more suitable analysis to pin down and evaluate the cause-effect relationship among all of the constructs with relatively complex models. Findings - Our results substantiate that the country of origin image positively affects brand awareness, brand associations, and brand image and advertising awareness positively affects brand awareness. Brand awareness gives positive effect only on brand association, which sustains a positive effect on brand image and brand loyalty. Brand image only has a positive effect on perceived quality, which again affects repurchase intention and brand loyalty. Brand loyalty also shows a positive effect on repurchase intention. Originality/value - Brand equity dimensions were viewed as cognitive and attitudinal outcomes of brand equity which affects repurchase intention. The drivers of brand equity were considered from the perspective of country of origin image that firms cannot control or mange, and advertising awareness which firms can control and manage. The findings also explored the relationships between cognitive and attitudinal brand equity.
