Internet addiction is becoming a growing phenomenon across the world due to the tendency of Internet overuse for varied reasons. The objective of this study is to identify the extent of Internet use and level of addiction among teenagers with the age ranging from 13 to 17 years old. This also include the risk factor and impact to their social life. The sample data were taken from several schools covering 500 students from the state of Selangor in Malaysia. The survey was done using an instrument from Internet Addiction Test (IAT) developed by Dr. Kimberly Young. This test had been modified to meet the requirements of the youngster’s mind-set in Malaysia. Demographics factors such as age, gender and race were examined apart from family and personal factors. The results of the study and Chi-square test summarizes that the level of internet addiction among teenagers in Selangor is p = 0.161 and tends to be minimal. We need to be aware of the level of Internet usage by teenagers so that measures could be made in place to deter or mitigate Internet addiction.

<p class="Normal1"><em>Commitment is the attitude or behavior of likes or dislikes shown by someone against the organization at work. Indonesia is recorded as a nurse who has a low organizational commitment (76%) so it harms services. This phenomenon in the hospital can be seen from the indicator of the high turnover rate of nurses which reaches 30.9% which exceeds the standard &lt;5%. Many factors affect organizational commitment. The purpose of this study was to analyze the Personal Factors Associated with Organizational Commitment of Hospital Nurses. This study is a cross-sectional analytic study and purposive sampling technique with a sample of 59 nurses. Chi-Square test results obtained personal factors that have a relationship with organizational commitment Nurse Hospital is age with p = 0,000 and education with p = 0,000, personal factors not related to organizational commitment are gender p = 1,053 and years of service with p = 1,147. Hospitals should conduct research/surveys on Organizational Commitment periodically as an evaluation material in the context of the organization's development and development in the future</em>.</p>

Background: Given the widespread prevalence and serious nature of Internet addiction (IA), this study aimed to estimate the prevalence of IA and assess the relationships between IA and combinations of physical activity (PA) and screen-based sedentary behavior (SB) among adolescents in China. Methods: This cross-sectional study surveyed 31,954 adolescents in grades 7 to 12 in Beijing. IA, PA, screen-based SB, and other information were obtained from a self-administrated questionnaire. The chi-square test and mixed-effects logistic regression model were applied to estimate the relationship between IA and combinations of PA and screen-based SB. Results: 6.2% of the surveyed adolescents reported IA and the prevalence of low PA/high screen-based SB, high PA/high screen-based SB, low PA/low screen-based SB, and high PA/low screen-based SB were 53.7%, 19.5%, 18.8%, and 8.0%, respectively. Mixed-effects logistic regression analysis showed that adolescents with low PA/high screen-based SB were 1.99 (95% confidence interval, 1.62–2.44, P < .001) times more likely to prefer IA than those with high PA/low screen-based SB. Conclusions: The prevalence of IA among Chinese adolescents is still high. Intervention programs like maintaining sufficient PA and reducing screen-based SB might contribute to reducing their IA.

Abstract Clinical-pathological sessions are a good method for solving diagnostic and/or therapeutic problems in patients with hemopathies. In these sessions, errors made during health care given to the patient can be detected. By analyzing how and why these errors are made, we can improve patient care and prevent further mistakes. The objective of this study is to describe 34 errors identified in 874 patients with hemopathies at clinical-pathological meetings in two centers, performed with the aim of solving a diagnostic problem and/or a therapeutic decision or due to a great interest of the case, in two institutions, over 22 years (1982–2004). An intererdisciplinary team of hematology specialists gathered every week at interactive sessions of about 45 minutes each, in both institutions. The methodology of sessions was: a description of the medical history of a patient in a one or two-page report and a revision of the different samples (peripheral blood, bone marrow and lymph node morphology, immunocytochemistry, flow-cytometry, cytogenetic and molecular studies) with the aid of a microscope and a TV monitor. A diagnostic and/or treatment were proposed at the end of the session. Eight-hundred and seventy-four reports were analyzed. All the diagnostics were classified: chronic lymphoproliferatives disorders (445), myeloproliferative and myelodysplastic syndromes (136), acute leukemias (136), other haematological diseases (74), non-haematological diseases (31), without a diagnosis after the meeting (52). We identified diagnostic (D) and therapeutic (T) mistakes and considered as the main causes of the medical error (mistake in the diagnosis and/or treatment): lack of expertise (LE), malpractice (MP), impetuosity (IM), bad logistic support (LS), inexplicable (IN). We divided the 22 years into two decades and each error was classified in one of these two groups. Our own mistakes (OM) and the errors made in other institutions (OI) were identified. A comparison between number of errors made in the first 11 years and the second 11 years was made using a Chi-square test. P&lt;0.05 was considered statistically significant. Thirty-four errors (4 %) were detected, being more D and T (20) rather than only D (14). The type of error detected was: 17 LE, 7 MP, 5 IM, 3 LS, 2 IN. Twenty errors were OM and 14 were made in OI. The difference in the proportion of errors detected during the first and the second decade (6.6 % vs 2.8 %, respectively) was statistically significant (p=0.05). No error led to the death of any patient or were life-threatening in any way. Errors may be made in the diagnosis and treatment of hematologic patients. Although the rate of error found appears to be high, it can be considered as low, since the cases were presented in scientific sessions because of diagnostic and/or therapeutic problems. One of the best ways of improving how to care for future patients is to detect and analyze the errors made. Many lessons can be learnt in this way.

SUMMARY Objectives: To evaluate the effect of flowable bulk-fill or conventional composite resin on bond strength and stress distribution in flat or mesio-occlusal-distal (MOD) cavity preparations using the microtensile bond strength (μTBS) test. Methods: Forty human molars were divided into two groups and received either standardized MOD or flat cavity preparations. Restorations were made using the conventional composite resin Z350 (Filtek Z350XT, 3M-ESPE, St Paul, MN, USA) or flowable bulk-fill (FBF) composite resin (Filtek Bulk Fill Flowable, 3M-ESPE). Postgel shrinkage was measured using the strain gauge technique (n=10). The Z350 buildup was made in two increments of 2.0 mm, and the FBF was made in a single increment of 4.0 mm. Six rectangular sticks were obtained for each tooth, and each section was used for μTBS testing at 1.0 mm/min. Polymerization shrinkage was modeled using postgel shrinkage data. The μTBS data were analyzed statistically using a two-way analysis of variance (ANOVA), and the postgel shrinkage data were analyzed using a one-way ANOVA with Tukey post hoc test. The failure modes were analyzed using a chi-square test (α=0.05). Results: Our results show that both the type of cavity preparation and the composite resin used affect the bond strength and stress distribution. The Z350 composite resin had a higher postgel shrinkage than the FBF composite resin. The μTBS of the MOD preparation was influenced by the type of composite resin used. Irrespective of composite resin, flat cavity preparations resulted in higher μTBS than MOD preparations (p&lt;0.001). Specifically, in flat-prepared cavities, FBF composite resin had a similar μTBS relative to Z350 composite resin. However, in MOD-prepared cavities, those with FBF composite resin had higher μTBS values than those with Z350 composite resin. Adhesive failure was prevalent for all tested groups. The MOD preparation resulted in higher shrinkage stress than the flat preparation, irrespective of composite resin. For MOD-prepared cavities, FBF composite resin resulted in lower stress than Z350 composite resin. However, no differences were found for flat-prepared cavities. Conclusions: FBF composite resin had lower shrinkage stress than Z350 conventional composite resin. The μTBS of the MOD preparation was influenced by the composite resin type. Flat cavity preparations had no influence on stress and μTBS. However, for MOD preparation, composite resin with higher shrinkage stress resulted in lower μTBS values.

There have been efforts to restrict older trucks in many jurisdictions all over the world. The primary goal of the restrictions is to minimize greenhouse gas emissions. In addition to the environmental benefits, it is also possible that the truck age restriction could contribute to the enhancement of traffic safety. Older trucks are subject to longer travel-miles than newer trucks and tend to have higher mechanical failure rates. Extremely few studies have been done to explore the impact of trucks’ age on their crash occurrence due to mechanical problems. This study aims to investigate the association between the truck crashes due to mechanical issues and the truck age. Two approaches are adopted to achieve the objective. First, a chi-square test reveals that the proportions of the mechanical failures among older trucks are higher than those among newer ones ( χ 2  = 256.199, p < 0.0001 ). Second, the modeling results indicate that the number of truck crashes due to mechanical failures is significantly increased by the truck age. The findings suggest that policies restricting older trucks should consider not only environmental effects but also traffic safety benefits.
