    In direct age-adjustment, a common age-structured population is used as standard. This population may actually exist (e.g., United States population, 1999) or may be fictitious (e.g., two populations may be combined to create a standard). In indirect age-adjustment, a common set of age-specific rates is applied to the populations whose rates are to be standardized. The simplest and most useful form of indirect adjustment is the standardized mortality ratio (SMR) (5).

    Increasing numbers of doctors are experiencing burnout now more than ever before and the worrying part is that what we see is just the tip of the iceberg. Burnout, a state of mental exhaustion caused by the doctor's professional life, is characterised by emotional exhaustion, depersonalisation and a reduced sense of accomplishment or success. Burnout has been largely ignored or under-recognised previously. This paper provides a perspective on burnout among doctors, including an overview of symptoms, the scale of the problem, the implications and causes of burnout and, finally, a strategic framework to provide a basis for managing it. Most importantly, professional bodies are urged to start taking steps to help troubled doctors. Medical Colleges should provide essential assistance, support and guidance as well as ensuring fair management and promotion policies.

    The purpose of this study is to measure and monitor the radon concentration from fabricated foamed light concrete, made of Portland cement, mine sand and granite. The concentration of radon released was measured using Radon Monitor Model 1027 from Sun Nuclear. The results of this research showed that the avearge radon concentration from foamed light concrete was 2.2 pCiL-1 L. Higher radon concentrations were detected after three days of measurements. Environment Protection Agency stated in its guidelines that radon concentration must lower than 4 pCiL-1 for a healthy environment. Thus, the use of foamed light concrete can be one of the alternatives to reduce radon concentration levels in human environment.

    Urbanisation increases the level of imperviousness in a catchment, and more runoff is converted from rainfall in urban areas. To mitigate this adverse situation, dispensed green infrastructure presents the best solution for delivering results in reducing stormwater impact. Green roofs and rain gardens are extensively studied and widely available in the literature, but this is not the case for green walls, which more often than not, are treated as ornaments. Thus, this study developed a computer-aided stormwater model that incorporates a green wall to investigate its effectiveness as an urban drainage system. The effectiveness of employing a green wall as a stormwater component is tested using USEPA SWMM 5.1 and the embedded bioretention cell interface. Four simulation models according to different conditions and precipitation input are tested, compared and discussed. The conditions include investigation of different soil types, average recurrence interval (ARI) and storm duration with design and observed rainfall. The results reveal that synthesis precipitation data, used in Scenario 1, 2 and 3, decreased runoff by more than half, at 55% on condition of one-year ARI and 5 minutes of storm duration. Meanwhile, Scenario 4 also shows a repetition of runoff reduction by half after the integration of the green wall using the observed rainfall data. Thus, it is verified that a green wall can be effectively used as an urban drainage system in reducing surface runoff.

    BACKGROUND AND AIMS: This systematic review analyzes and summarizes gambling-related findings from the nationally representative US National Epidemiological Survey on Alcohol and Related Conditions (NESARC) data.

    METHODS: Systematic literature searches in accordance with PRISMA guidelines found 51 eligible studies that met inclusion criteria. Eight studies utilized both Waves 1 and 2 NESARC data, and selection of sample sizes varied from 185 to 43,093 individuals, consistent with specified research objectives of each study.

    RESULTS: The prevalence of lifetime pathological gambling was 0.42% (0.64% among men, 0.23% among women), while past-year prevalence was 0.16%. Pathological gambling rates were generally higher in populations with substance-use disorders and other psychiatric diagnoses. Rates of adverse childhood experiences and suicidal attempts were higher among individuals with problem or pathological gambling. Early-onset gamblers were more likely to be male, be never married, have incomes below $70,000, belong to younger cohorts and have Cluster B personality disorders, but less likely to be diagnosed with mood disorders. While pathological gambling was related to obesity, increased stress, and poorer physical health among general age groups, recreational gambling was linked with improved physical and mental functioning in older adults.

    CONCLUSIONS: The NESARC has provided important information on the correlates of pathological gambling and subdiagnostic patterns of gambling behaviors. Additional studies should examine these relationships in the current gambling environment and longitudinally with aims of implementing policies to improve the public health.

    The success story of the Veterans Health Administration (VHA) within the US Department of Veterans Affairs has been well documented and is generally well known. What is generally not known is that the VHA's clinical information system, known as VistA, and the computerized patient record system clinical user interface front end have been successfully transported and implemented to a number of non-VHA healthcare organizations across the United States. Moreover, VistA software modules have been installed, or are being considered for installation, in healthcare institutions around the world in countries such as Mexico, Finland, Jordan, Germany, Nigeria, Egypt, Malaysia, India, Brazil, Pakistan and Samoa.

    A study was carried out to determine short term diurnal radon concentration at five locations in Malaysia. Two locations (KG & AP) are former tin mining areas that has been converted to housing area and training centre respectively, one a relatively new city (SA), that was formerly a rubber and oil palm plantation area, one older cities (KB) and one housing complex by the sea (LP). The study was carried out in 2005, 2006 and 2007 using a diffused-junction photodiode sensor continuous radon monitor. The monitor is recognized by the USEPA. In each location, measurements were carried out on at least ten sites. Former tin mining areas of KG and AP shows up to seven times higher indoor average than the average in the other three locations. However the indoor average in all locations is still below the action level of 4 pCiL-1. For outdoor, the former tin mining areas average concentration was higher than the global average of 0.4 pCiL-1. For the twenty four hours temporal variation the trend indicated that former tin mining areas concentration are always higher, and at time up to six fold higher. The hourly variation of all locations follows an identical trend of high concentration during early to late morning and drop in the afternoon till evening. The outdoor twenty four hour temporal average of former tin mining areas is consistently higher than the outdoor global average of 0.4 pCiL-1. The strong correlation between indoor and outdoor concentration at AP, indicates that indoor radon might originates from outdoor environment. The study was also extended to estimate the effective dose (mSvyr-1) of Rn-222 to the public.

    Radon-222 emanation from selected locally produced samples of building materials, used in Malaysia were measured using the Professional Continuous Radon Monitor Model 1027, which is a patented electronic detecting-junction photodiode sensor to measure the concentration of radon gas. Each sample was placed for 72 hours inside a 3.11 x 10 -2 m 3 sealed container. It was found that the average radon concentration Bqm -3 of air for concrete bricks, concrete brick with cemented coatings, concrete brick with cemented coatings and paint samples were, 303.7 Bq/m 3, 436.6 Bqm -3, and 410.7 Bqm -3, respectively. (Bqm -3 ) for brown clay brick, brown clay brick with cemented coatings, brown clay brick with cemented coatings and paint were 166.5 Bqm -3, 166.5 Bqm -3, and 148 Bqm -3, respectively. (Bqm -3 ) for sample of compact ceramic tile was 0 Bqm -3. The findings show that concrete brick samples are important source of radon emanation, while brown clay brick have been accepted as the recommendation of the U.S. Environmental Protection Agency (EPA), and ceramic tiles had no emanation of radon gas due to their compact surface, or the glazed layer created on the tile surface during the manufacturing process, which blocks radon emanation. A positive correlation between radon emanation and radium content has been observed for both brown clay brick and concrete brick samples whereas a negative correlation for ceramic tile has been observed. Consequently from the findings, in order to reduce radon emanation and radon exposure in house dwellings and in addition to EPA recommendation of sealed cracks and established good ventilation, we recommend concrete walls to be painted and concrete floors to be paved with ceramic tiles.

    The use of serious games as digital medicine started in recent years as the United States Food and Drug Administration granted Class 1 or 2 device clearance to serious games or game-like technologies. This encouraging trend motivates interdisciplinary cooperation between experts in the medical sciences and the game industry because the Northern American pharmaceutical revenues have exceeded USD1 trillion globally since 2014. The potential of this lucrative business opportunity may attract fund providers and venture capitalists to support game-related research and development projects. The author elaborates his activities and experiences in the United States in FY2017/2018 as a Humphrey fellow from Malaysia. Specifically, the research and development trend of serious games for cognitive function in the academic and the game industry has positive impact on how medical doctors and practitioners in low- and middle-income countries may use or develop games as digital medicine.

    Technical benefit of incorporation of Palm Oil Clinker (POC) in cement-based applications has been proven in recent
    studies. The aim of this work was to assess the heavy metal leaching behavior to ensure environmental safety of using
    POC in cement-based applications. The chemical composition, morphology, total organic carbon (TOC) and mineralogy
    were determined using XRF, FESEM, TOC analyzers and XRD to select appropriate chemical reagents for complete digestion.
    , HF and HClO4
    were used for digestion of POC to measure heavy metal content using ICP-MS. The chemical reagents
    COOH, NH2
    OH-HCl, H2
    and HF+HNO3
    +HCl were used for extraction of acid soluble, reducible,
    oxidizable and residual fractions of heavy metals in POC, respectively. The leaching toxicity of the POC was investigated
    by the USEPA 1311 TCLP method. The result showed the presence of Be, V, Cr, Ni, Cu, Zn, As, Se, Ag, Cd, Ba and Pb with
    levels of 5.13, 11.02, 2.65, 1.93, 45.43, 11.84, 15.07, 0, 0, 81.97 and 1.76 mg/kg, respectively, in POC. The leaching value

    OBJECTIVE: The purpose of this study was to determine the feasibility of a chiropractic practice-based research network to investigate the treatment of acute neck pain (ANP) and to report resulting findings.
    METHODS: Participating chiropractors recruited sequentially presenting ANP patients on their initial visit to the office. Patients were treated by the chiropractors using their usual methods. Data were prospectively collected by having patients complete the Neck Disability Index, Characteristic Pain Intensity score, and a patient satisfaction questionnaire. Questionnaires were completed during routine office visits at baseline and then at weeks 1, 2, 4, 8, and 26, either in the office or by mail.
    RESULTS: Ten chiropractors supplied data on 99 patients. The number of cases contributed by each of the participating chiropractors ranged from 1 to 54, with a mean (SD) of 9.2 (10.5). Mean (SD) Neck Disability Index scores were 36 (17.9) at baseline and 9.8 (12.2) at the final evaluation; the Characteristic Pain Intensity scores were initially 55.3 (20.4) and were 24.5 (21.5) at the final evaluation. Transient minimal adverse effects were reported by chiropractors for only 7 (7.8%) patients. No serious adverse reactions were reported.
    CONCLUSION: The practice-based research methodology used in this study appears to be a feasible way to investigate chiropractic care for ANP, and its methodologies could be used to plan future research.

    Numerous studies are demonstrating that engaging undergraduate students in original research can improve their achievement in the science, technology, engineering, and mathematics (STEM) fields and increase the likelihood that some of them will decide to pursue careers in these disciplines. Associated with this increased prominence of research in the undergraduate curriculum are greater expectations from funders, colleges, and universities that faculty mentors will help those students, along with their graduate students and postdoctoral fellows, develop an understanding and sense of personal and collective obligation for responsible conduct of science (RCS). This Feature describes an ongoing National Research Council (NRC) project and a recent report about educating faculty members in culturally diverse settings (Middle East/North Africa and Asia) to employ active-learning strategies to engage their students and colleagues deeply in issues related to RCS. The NRC report describes the first phase of this project, which took place in Aqaba and Amman, Jordan, in September 2012 and April 2013, respectively. Here we highlight the findings from that report and our subsequent experience with a similar interactive institute in Kuala Lumpur, Malaysia. Our work provides insights and perspectives for faculty members in the United States as they engage undergraduate and graduate students, as well as postdoctoral fellows, to help them better understand the intricacies of and connections among various components of RCS. Further, our experiences can provide insights for those who may wish to establish "train-the-trainer" programs at their home institutions.

    Garis panduan saringan telinga tengah oleh American Speech-Language-Hearing Association (ASHA) telah menyarankan agar pendekatan kuantitatif digunakan untuk menginterpretasi keputusan timpanogram. Berbanding pendekatan kualitatif yang digunapakai untuk menginterpretasi timpanogram sebelum ini, pendekatan kuantitatif adalah lebih sesuai kerana ianya bersifat objektif serta dapat diaplikasi dengan peralatan timpanometer komersial yang terdapat di pasaran sekarang. Kajian ini bertujuan untuk mendapatkan nilai mutlak ciri timpanometri iaitu puncak statik admitan akustik dikompensasi (Puncak Ytm), kelebaran timpanogram (TW) dan isipadu salur telinga luar (Vea) di kalangan kanak-kanak pra-sekolah normal dan Sindrom Down. Lima belas kanak-kanak normal dan 12 kanak-kanak Sindrom Down yang memenuhi kriteria pemilihan subjek terlibat di dalam kajian ini. Nilai purata Puncak Ytm dan Vea bagi kanak-kanak normal masing-masing adalah 0.36 mmho dan 0.57 cm3 manakala kanak-kanak Sindrom Down mencatat nilai purata 0.14 mmho dan 0.38 cm3. Kanak-kanak normal dan Sindrom Down masingmasing mencatatkan nilai purata TW 99.73 dan 148.65 daPa. Analisis statistik menunjukkan terdapat perbezaan yang signifikan di antara kedua-dua kumpulan subjek bagi ketiga-tiga nilai parameter timpanometri yang diperolehi.

    The number of hip replacement procedures in the United States is expected to increase four-fold by 2030. Younger patients, those under 65 years old, are expected to account for 53% of hip replacements in 2030, compared to 44% in 2005. As midterm review results are becoming available worldwide now, the problem that perplexes surgeons is the alteration of limb length which has been an ancillary goal of Total Hip Replacements. The lack of modularity in neck lengths and offsets in resurfacing arthroplasty clearly limits the change in limb lengths achievable for the hip. The goal of this study is to scrutinize the various parameters that affect implant seating in resurfacing arthroplasty and to determine the alteration of limb length achievable during surgery.

    The paper focused on the examination and testing of local exhaust ventilation (LEV) systems at one of Electrical Company to check the transport velocity whether it meet the recommended American Governmental Industrial Hygienist (ACGIH) Standard. The industrial hygiene approaches, AREC (Anticipating, Recognize, Evaluate and Control) were adopted in this study. This is to ensure that the LEV system installed has the optimum efficiency to extract out the contaminants from the workstation. Objective of this study is to make comparison with previous and current monitoring data. The efficiency and the other parameter measured will be the main source to analyze for the particular applications. The differential of data was discussed and several recommendations are proposed to make sure the LEV system performance is excellent.

    A laser endoscopy system was developed in 2012. The system allows blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) to be performed as modes of narrow-band light observation; these modes have been reported to be useful for tumor detection and characterization. Furthermore, an innovative endoscopy system using four-light emitting diode (LED) multilight technology was released in 2016 to 2017 in some areas in which laser endoscopes have not been approved for use, including the United States and Europe. This system enables blue light imaging (this is also known as BLI) and LCI with an LED light source instead of a laser light source. Several reports have shown that these modes have improved tumor detection. In this paper, we review the efficacy of BLI and LCI with laser and LED endoscopes in tumor detection and characterization.

    This research proposes a point forecasting method into Markov switching autoregressive model. In case of two regimes, we proved the probability that h periods later process will be in regime 1 or 2 is given by steady-state probabilities. Then, using the value of h-step-ahead forecast data at time t in each regime and using steady-state probabilities, we present an h-step-ahead point forecast of data. An empirical application of this forecasting technique for U.S. Dollar/ Euro exchange rate showed that Markov switching autoregressive model achieved superior forecasts relative to the random walk with drift. The results of out-of-sample forecast indicate that the fluctuations of U.S. Dollar/ Euro exchange rate from May 2011 to May 2013 will be rising.
