Background: Prostate cancer (PC) is one of the leading causes of death, especially in developed countries. The human development index (HDI) and its dimensions seem correlated with incidence and mortality rates of PC. This study aimed to assess the association of the specific components of HDI (life expectancy at birth, education, gross national income per 1000 capita, health, and living standards) with burden indicators of PC worldwide. Materials and Methods: Information of the incidence and mortality rates of PC was obtained from the GLOBOCAN cancer project in year 2012 and data about the HDI 2013 were obtained from the World Bank database. The correlation between incidence, mortality rates, and the HDI parameters were assessed using STATA software. Results: A significant inequality of PC incidence rates was observed according to concentration indexes=0.25 with 95% CI (0.22, 0.34) and a negative mortality concentration index of -0.04 with 95% CI (-0.09, 0.01) was observed. Conclusions: A positive significant correlation was detected between the incidence rates of PC and the HDI and its dimensions including life expectancy at birth, education, income, urbanization level and obesity. However, there was a negative significant correlation between the standardized mortality rates and the life expectancy, income and HDI.

Background: With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. Methods: A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. Results: The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. Conclusion: OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

현재 국내에서는 TMA(Tissue Mineral Analysis) 결과를 독자적이며 전문적으로 해석할 수 있는 의료 정보 데이터베이스가 없을 뿐 아니라, TMA 관련 데이터베이스가 있다 하더라도 의료기관에서 사용하기 어려운 매우 낮은 수준이므로 양질의 의료서비스를 제공하기 어려운 실정이다. 또한 국내에서 주로 사용되는 TMA 방법은 미국에 의뢰한 후 보내온 분석결과에 의존하게 되는데, 이때의 결과는 서구식 생활패턴에서 비롯된 데이터베이스에 의해 분석된 것이므로 동양인의 경우 특히 검사결과의 신뢰성 문제가 발생하게 된다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위해 국내 임상자료를 바탕으로 TMA 관련 국내 최초 지능적 의료정보시스템(ITS: Intelligent TMA Information System)을 개발하였다. ITS는 TMA 자료를 다단계 통계분석 방법에 의한 결성트리 분류기를 이용하여 분류하고 다중 퍼지 규칙베이스를 구축하여 복잡한 자료론 추론하도록 구축하였다.

Purpose: At present, there are a variety of serious patient safety incidents related to problems in health information technology (HIT), specifically involving electronic medical records (EMRs). This emphasizes the need for an enhanced electronic medical record system (EMRS). As such, this study analyzed both the nature of and potential to prevent incidents associated with HIT/EMRS based on data from the Korea Patient Safety Reporting and Learning System (KOPS). Methods: This study analyzed patient safety incidents submitted to KOPS between August 2016 and December 2019. HIT keywords were used to extract HIT/EMRS incidents. Each case was reviewed to confirm whether the contributing factors were related to HIT/EMRS (HIT/EMRS-related incidents) and if the incident could have been prevented (HIT/EMRS-preventable incidents). The selected reports were summarized for general clarity (e.g., incident type, and degree of harm). Results: Of the 25,515 obtained reports, 2,664 incidents (10.4%) were HIT-related, while 2,525 (9.9%) were EMRS-related. HIT/EMRS-related incidents were the third largest type of incident followed by 'fall' and 'medication incidents.' More than 80% of HIT/EMRS-related incidents were medication-related, accounting for approximately one-third of the total number of medication incidents. Approximately 10% of HIT/EMRS-related incidents resulted in patient harm, with more than 94% of these deemed as preventable; further, sentinel events were wholly preventable. Conclusion: This study provides basic data for improving EMR use/safety standards based on real-world patient safety incidents. Such improvements entail the establishment of long-term plans, research, and incident analysis, thus ensuring a safe healthcare environment for patients and healthcare providers.

Dining-out behavior is associated not only with socio-demographic characteristics such as gender, education, occupation, residence, and marital status, but also with individual preferences, such as eating-out activities, interests, and opinions. We investigated dining-out behaviors and their associated factors. Announcements by health practioners and the Chief of Dong Office were used to recruit 739 residents (217 males and 522 females) in Chuncheon, Korea. Information on the frequency and reasons for eating out, the standards for meal selection, and the overall satisfaction with restaurants, based on taste, nutrition, amount, price, service, sanitation, and subsidiary facilities of restaurants, was obtained through personal interviews with a structured questionnaire. Among all respondents, 46.3% of subjects ate outside of the home once or twice a month, and 33.8% reported that they ate out only a few times a year, or never. This was much higher than the national average of 52.0% as reported by the Korean National Health and Nutrition Survey (KNHNS) in 2001. The frequency of eating out differed significantly according to age (p=0.001), family income (p<0.001), residential area (p<0.001), and educational level (p<0.001). The most common reasons for dining out were meetings (46.7%), followed by special celebrations (15.4%), and enjoyment (11.2%). Korean food (55.3%) was the most frequently selected type of meal when eating out, and food was most often selected based on personal preferences (41.4%) and taste (29.8%); only 5.5% and 7.7% of subjects considered nutrition or other factors (e.g., sanitation), respectively. The results showed that the frequency of eating out for Chuncheon residents was much lower than the national average; in addition, eating-out behaviors depended on the residents' socio-demographic and personal characteristics.

We have developed a device for recording biological data by inserting three electrodes and a needle with an angular velocity sensor into the moth for the purpose of measuring the electromyogram of the flapping and the corresponding lift force. With this measurement, it is possible to evaluate the moth-physiological function of moths, and the amount of pesticides that insects are exposed to (currently LD50-based standards), especially the amount of chronic low-concentration exposure, can be reduced the dose. We measured and recorded 2-channel electromyography (EMG) and angular velocity corresponding to pitch angle (pitch-like angle) associated with wing flapping for 100 sweet potato hawkmoths (50 females and 50 males) with the animals suspended and constrained in air. Overall, the angular velocity and amplitude of EMG signals demonstrated high correlation, with a correlation coefficient of R = 0.792. In contrast, the results of analysis performed on the peak-to-peak (PP) EMG intervals, which correspond to the RR intervals of ECG signals, indicated a correlation between ΔF fluctuation and angular velocity of R = 0.379. Thus, the accuracy of the regression curve was relatively poor. Using a DC amplification circuit without capacitive coupling as the EMG amplification circuit, we confirmed that the baseline changes at the gear change point of wing flapping. The following formula gives the lift provided by the wing: angular velocity × thoracic weight - air resistance - (eddy resistance due to turbulence). In future studies, we plan to attach a micro radio transmitter to the moths to gather data on potential energy, kinetic energy, and displacement during free flight for analysis. Such physiological functional evaluations of moths may alleviate damage to insect health due to repeated exposure to multiple agrochemicals and may lead to significant changes in the toxicity standards, which are currently based on LD50 values.
