The purposes of this study was to investigate importance and performance for coffee quality attributes in Korean and Chinese university students by 3 types of coffee; coffee in coffee houses, coffee in vending machines and canned/bottled coffee. Survey was done for 360 students in Daejeon with developed questionnaires including general information, favorite type of coffee and 15 quality attributes of coffee. Finally, data from 168 Korean and 126 Chinese university students was used for statistical analysis by SPSS 18.0 package program. Results of this study were as follows: for favorite type of coffee, the rates of coffee in coffee houses, coffee in vending machines and canned/bottled coffee were 43.0% 34.8% and 22.2% in Korean students and 8.7%, 78.0%, and 12.2% in Chinese students, respectively. Comparing Chinese students and Korean students showed higher importance for several quality attributes of coffee in coffee house (p < 0.05), but lower importance for most quality-attributes of coffee in vending machine (p < 0.05) and canned/bottled coffee (p < 0.05). According to importance and performance analysis, strategies for increasing satisfaction were to improve 'price' of canned/bottled coffee in Korean students, and 'taste', 'volume', 'concentration' and 'variety' of canned/bottled coffee and 'freshness' of coffee in vending machine in Chinese students. These results suggested that differentiated marketing plans between Korean and Chinese university students should be needed in coffee industry.

Hydatid disease imposing serious threat on human health and great loss in live-stock pastoralism remains a major public health problem in western China. To assess and monitor the effect of control program on transmission dynamics, we used the prevalence of cystic echinococcosis in slaughtered sheep at slaughterhouse as an indicator during the period of 2007 to 2013 in Emin County, Xinjiang Uygur Autonomous Region, China. The results showed a significant decline trend of prevalence in all age groups during the 7 years when the control program was implemented; particularly, the rate was reduced by 72% after first 3 years. Among the sheep slaughtered, the age distribution evidenced that the prevalence increased significantly as the sheep grew older. The baseline data indicated that the rate was 4.5% at the age <1, 6.7% at age 2~, and reached to the highest 17.9% at age ${\geq}4$ years. Earlier response to the intervention pressure was seen in the sheep at the younger age. Significant decline started from 2008 at the age <1, from 2009 at age of 1~, 2010 at 2~ to 3~, and the latest, in 2012 at age ${\geq}4$. This study demonstrated that the prevalence of cystic echinococcosis in slaughtered sheep may be used as an indicator to assess and monitor the transmission status during and after control program providing information for betterment of performance to sustain control strength.

Hydatid worms, hosted by humans and animals, impose serious human health risk and cause significant livestock production loss. To better understand the disease infection status in Xinjiang, China, we investigated the disease epidemics in 4 livestock animals, i.e., cattle, sheep (both sheep and goat), camels, and horses, slaughtered at the abattoirs in Urumqi, Yining, Tacheng, and Altay areas. The results showed that the animals were infected at different rates, in the order of sheep (9.8%), cattle (8.4%), camels (6.8%), and horses (4.3%). The infection rates were found to be different between the abattoirs in various regions even for the same animals. For sheep, the rates increased significantly as the animals grew older. It was 1.9% before 1 year of age and increased to 8.2% in the age of 1-2 years, and further increased to 12.3% when the animals were 3-4 years old, and reached 17.2% when they were 5-6 year old. Sheep older than 6 years had an infection rate of 19.5%. This study demonstrates that the 4 livestock animals in the pastoral areas in Xinjiang were infected by the parasites to various extend. This study is the first systematic investigation of the hydatid worms in various livestock animals in Xinjiang, China, which provides epidemiological information about the infection of hydatid worms in livestock, and is valuable in developing strategies for prevention and control of the hydatid disease.

The aim of this study was to conduct a freshwater snail survey in Mae Lao agricultural basin to assess the diversity with a focus on habitat types and their larval trematode infections. Snails were collected and examined in 14 sites of Mae Lao agricultural basin from August 2016 to October 2017. A total of 1,688 snail individuals were collected and classified into 7 families, 8 genera, and 12 species. Snail diversity and habitat types were higher in rice paddies than irrigation canals and streams. The most abundant species was Bithynia siamensis siamensis, representing 54.6% of the sample. Three species of snails act as first intermediate host were found with cercarial infections. They were Filopaludina sumatrensis polygramma, B. s. siamensis, and Melanoides tuberculata. The cercariae were categorized into 7 types; echinostome, monostome, gymnocephalous, virgulate, parapleurolophocercous, pleurolophocercous and megalurous cercariae. Parapleurolophocercous cercariae constituted the most common type of cercariae recovered, contributing 41.2% of all infections in snails. Echinostome metacercariae infections were found in 6 snail species with 7.6% prevalence. In addition, the metacercaria of avian trematode, Thapariella sp. were found in Filopaludina spp. snails and B. funiculata with a prevalence of 0.5%. This is the first report for Thapariella metacercariae in the snail host, B. funiculata, and also confirmed that viviparid and bithyniid snails act as the second intermediate hosts of this trematode. This work will provide new information on the distribution and intermediate host of trematode in this area.

Waterborne parasite infections are considered a reemerging threat. Most studies on the epidemiology of human cryptosporidiosis, giardiasis, and amebiasis have been carried out in developed countries, and there is little data on the occurrence of these infections in other areas. The objective of this study was to investigate the presence of waterborne parasites such as Cryptosporidium parvum, Giardia lamblia and Entamoeba histolytica in various water samples in Ankara, turkey. A total of 85 samples were examined, 43 from the municipal water supply, 34 from wells, 6 from the Ankara River, and 2 from two untreated dams; by conventional microscopy, immunologically and by polymerase chain reaction (PCR). Oocysts of C. parvum and cysts of G. lamblia were detected by using an indirect fluorescence (antigen) assay, whereas an enzyme linked immunosorbent assay was used to detect the cysts of E. histolytica and E. dispar. In addition, PCR was used for E. histolytica, E. dispar, C. parvum and G. lamblia detection. G. lamblia was found in 2 of the 34 well water samples, and parasites were found in 3 of the 6 Ankara River samples. The 1$\^$st/ contained E. histolytica cysts and Strongyloides stercoralis larvae. the 2$\^$nd/ E. histolytica cysts, and Trichuris trichiura eggs, and the 3$\^$rd/ C. parvum oocysts only. No parasite was observed in the municipal water samples and untreated dam water samples. These results extend our knowledge on waterborne parasites, such occurrence information on waterborne pathogens assists the management and treatment of municipal water.

Background: Occupational accidents are unplanned events that cause damage. The socio-economic impacts and human costs of accidents are tremendous around the world. Many fatalities happen every year in workplaces such as electricity distribution companies. Some electrical injuries are electrocution, electric shock, and burns. This study was conducted in an electricity distribution company (with rotational 12-hour shift work) in Iran during an 8-year period to survey descriptive factors of injuries. Methods: Variables collected included accident time, age of injured worker, employment type, work experience, injury cause, educational background, and other information about accidents. Results: Results indicated that most of the accidents occurred in summer, and 51.3% were during shift work. Worker negligence (malpractice) was the cause of 75% of deaths. Type of employment had a significant relationship with type of injuries (p < 0.05). Most injuries were electrical burns. Conclusion: High rate of accidents in summer may be due to the warm weather or insufficient professional skills in seasonal workers. Shift workers are at risk of sleep complaints leading to a high rate of work injuries. Acquiring knowledge about safety was related to job experiences. Temporary workers have no chance to work all year like permanent workers, therefore impressive experiences may be less in them. Because the lack of protective equipment and negligence are main causes of accidents, periodical inspections in workshops are necessary.

Based on electrophysiological retina mechanism, a retina model is proposed, which has similar response characteristics compared with the real primate retina. Photoreceptors, horizontal cells, and bipolar cells are modeled based on the previously studied retina models. And amacrine cells known to have relation to movements detection, and bipolar cell terminals are newly modeled using 3 NDP mechanism. The proposed model verified by analyzing the spatial response characteristics to stationary and moving stimuli, and characteristics for different speeds. Through this retina model, human vision system could be applied to computer vision systems for movement detection, and it could be the basic research for the implantable artificial retina.

Purpose: By identifying the actual profile of emergency medical personnel's pre-admission infection control practices, this study intended to provide a basic reference material for the improvement and reorientation of pre-admission infection control measures, and thereby help establish an effective plan for pre-admission infection control activities. Methods: Total 119 EMT's working for Jeollabuk-do Provincial Fire Defense HQ were asked to join a structured questionnaire survey from June to August 2006. Results: 1. It was found that 56.1% respondents answered no guideline available on the prevention of infection. Out of our rescue brigade members who knew about relevant guideline available, 34.2% respondents answered that their department conducted quality control program for the guideline. 2. For protective outfit in emergency practice, it was found that most respondents put on gloves or nothing at all(38%), which was followed by sterile gloves(29.2%), disposable mask(26.9%), gown(4.3%) and protective goggle(1.6%). And it was noted that all respondents(100%) washed out any clothing contaminated with somatic secretion on their own. 3. For a question about any experience in emergency activities exposed to infectious diseases, it was found that most of all respondents(77.9%) answered 'No', which was followed by 'Don't Know'(18.6%) and Yes(3.9 %). 4. For a question about any experience in inquiring of patients about infectious diseases, it was found that most respondents(49.4%) answered 'Yes' and 'Sometimes'(9.1%). It was noted that 20.2% respondents had extra medical examination in medical institution in terms of whether they were exposed to infectious diseases, apart from regular medical examination. Conclusions: In order to protect 119 EMT's from infectious diseases, it will be necessary to acquire emergency medical staffs specializing in infection control and organize corresponding personnel training units to keep providing reorientation and evaluation. In addition, it will be also necessary to supply them with a full set personal protection apparatuses and other equipments required for disinfection and sterilization.

This paper proposes a low-cost visual analyzer algorithm of human body motion for real-time applications such as human-computer interfacing, virtual reality applications in medicine and telemonitoring of patients. To reduce cost of its use, we design the algorithm to use a single camera. To make the proposed system to be used more conveniently, we avoid from using optical markers. To make the proposed algorithm be convenient for real-time applications, we design it to have a closed-form with high accuracy. To design a closed-form algorithm, we propose an idea that formulates motion of a human body joint as a 2D universal joint model instead of a common 3D spherical joint model, without any kins of approximation. To make the closed-form algorithm has high accuracy, we formulates the estimation process to be an optimization problem. Thus-desined algorithm is applied to each joint of the human body one after another. Through experiments we show that human body motion capturing can be performed in an efficient and robust manner by using our algorithm.

Purpose: To provide clear estimates of the adoption and use of electronic nursing records (ENRs) with standard terminology in Korea and identification of the scope and use as well as perceived or potential benefits of ENRs. Methods: A survey was done of 733 hospitals at three levels: tertiary advanced hospitals, general hospitals, and community hospitals. After performing a literature review a modified version of an existing survey tool was used for 2 months in 2012. The collected information related to EHR functionality and coverage of nursing documentation and nursing process, application of standard terminology, and perceived satisfaction and benefits of ENRs. Results: The response rate was 39.4% (289/733), and 202 hospitals (70.1%, 95% CI64.8~75.5%) of the respondents had ENR systems (82.5% of tertiary hospitals, 66.7% of general hospitals, and 70.1% of community hospitals). Out of these hospitals less than 10% had ENRs fully covering nursing documentation. The adoption rate of standard terminology was 55%, and hospital satisfaction with ENRs was 70%. But personalized care was identified as needing improvement in ENRs. Conclusion: The ENR adoption rate was high but there are many potential opportunities for improving ENR systems in terms of the data standardization and personalized care.
