Purpose: The aim of this study was to identify the effects of community mapping based on volunteered Geographic Information System on smoking prevention among female middle school students. Methods: This study used a triangulation method which integrated quantitative data from a "pre-post" study on a nonequivalent control group and qualitative data from focus group interviews. Data was collected from 4 August 2015 to 10 January 2016. The experimental group (n=24) participated in community mapping along with education on smoking prevention and the control group (n=28) participated only in routine education. Both groups were measured on their knowledge and attitude related to smoking prevention through self-report questionnaires. The quantitative data was analyzed by descriptive statistics, $x^2$ analysis, and t-test using SPSS 23.0. The qualitative data was collected through focus group interviews to investigate the social-environmental effect of smoking prevention. Results: Knowledge related to smoking prevention was significantly higher (t=2.591, p=.013) in the experimental group than the control group. But attitude related to smoking prevention did not show significant differences between the two groups. When asked about their experiences of the community mapping program, it turned out to be a process where they could learn practical knowledge related to smoking prevention and experience their individual practices manifested as collective intelligence while working together with community members. The study found that community mapping had an effect on smoking prevention from a social and environmental aspect. Conclusion: To be more effective, school education on smoking prevention should be provided in connection with the community. It is also desirable to provide an opportunity where adolescents can experience discovering and solving practical problems along with their own community.

Objective: Oxidative stress (OS) is a pathological process arising from the excessive production of free radicals in the body. It has the potential to alter animal gene expression and cause damage to the jejunum. However, there have been few reports of changes in the expression of long noncoding RNAs (lncRNAs) in the jejunum in piglets under OS. The purpose of this research was to examine how lncRNAs in piglet jejunum change under OS. Methods: The abdominal cavities of piglets were injected with diquat (DQ) to produce OS. Raw reads were downloaded from the SRA database. RNA-seq was utilized to study the expression of lncRNAs in piglets under OS. Additionally, six randomly selected lncRNAs were verified using quantitative real-time polymerase chain reaction (qRT-PCR) to examine the mechanism of oxidative damage. Results: A total of 79 lncRNAs were differentially expressed (DE) in the treatment group compared to the negative control group. The target genes of DE lncRNAs were enriched in gene ontology (GO) terms and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathways. Chemical carcinogenesis-reactive oxygen species, the Foxo signaling pathway, colorectal cancer, and the AMPK signaling pathway were all linked to OS. Conclusion: Our results demonstrated that DQ-induced OS causes differential expression of lncRNAs, laying the groundwork for future research into the processes involved in the jejunum's response to OS.

There are many joint fissures distributed in the engineering rock mass. In the process of geological history, the underground rock mass undergoes strong geological processes, and undergoes complex geological processes such as fracture breeding, expansion, recementation, and re-expansion. In this paper, the damage-stick-slip process (DSSP), an analysis model used for rock mass failure slip, was established to examine the master control and time-dependent mechanical properties of the new and primary fractures of a multi-fractured rock mass under the action of stress loading. The experimental system for the recemented multi-fractured rock mass was developed to validate the above theory. First, a rock mass failure test was conducted. Then, the failure stress state was kept constant, and the fractured rock mass was grouted and cemented. A secondary loading was applied until the grouted mass reached the intended strength to investigate the bearing capacity of the recemented multi-fractured rock mass, and an acoustic emission (AE) system was used to monitor AE events and the update of damage energy. The results show that the initial fracture angle and direction had a significant effect on the re-failure process of the cement rock mass; Compared with the monitoring results of the acoustic emission (AE) measurements, the master control surface, key blocks and other control factors in the multi-fractured rock mass were obtained; The triangular shaped block in rock mass plays an important role in the stress and displacement change of multi-fracture rock mass and the long fissure and the fractures with close fracture tip are easier to activate, and the position where the longer fractures intersect with the smaller fractures is easier to generate new fractures. The results are of great significance to a multi-block structure, which affects the safety of underground coal mining.

Purpose: The purpose of this study were to develop a respiratory communicable disease prevention program for preschoolers and measure it's effects. Method: The respiratory communicable disease prevention program for preschoolers consisted of texts, cartoons, photographs, discussions, demonstrations, puzzle games, die games, compensation/reinforcement, and token economy which were directed under the systematic design of instruction by Dick ％amp; Carey. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 45 preschool children who are attending 3 different district nursery schools and they were matched by the age, pretest knowledge, and pretest behavior. The instrument used in this study was criterion referenced test items that were developed by a researcher for evaluating the subject's knowledge, attitude, and behavior about respiratory communicable disease prevention. A pretest was administered a week before treatment. Experimental group Ⅰ was administered by the treatment of respiratory communicable disease prevention program. Experimental group Ⅱ was administered by above program with token economy program. The posttest was conducted on the eighth day. The third test for behavior was completed 15th day. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with Kruskal Wallis test, ANCOVA, ANOVA, Duncan's test and paired t-test. Result: 1) There was a significant difference in knowledge between the experimental groups and control group(F=5.89, P=0.0197). 2) There was a significant difference in attitude between the experimental groups and control group(F=3.29, P=0.0469). 3) There was a non-significant difference in behavior between the experimental groups and control group(F=0.00, P=0.9512). 4) In the experimental groupⅡ, there was highly significant increase in behavior after token economy(t=4.5252, P=0.0005). Conclusion: It was found that the respiratory communicable disease prevention program for preschool children was effective in changing the preschoolers' knowledge and attitude on the respiratory communicable disease prevention, but not enough for changing the preschoolers' behavior. Token economy was improved as an effective and strong method for inducing desirable changes of preschoolers' behavior.

This cross-sectional descriptive and qualitative study was aimed to study the people participation and their approaches toward the human carcinogenic liver fluke, Opisthorchis viverrini, prevention and control in Ban Chaun sub-district administrative organization (BCSAO) and Bamnet Narong sub-district municipality (BNSM), Bamnet Narong district, Chaiyaphum Province, Thailand between June 2013 and February 2014. Participants were purposive selected, included chiefs of sub-district administrative organizations, sub-district municipalities, sub-district health promotion hospitals (SHPHs), heads of village, and a further sample was selected with a multi-stage random sampling for public health volunteers, and villagers. The pre-designed questionnaire contained items for individualized status and the participatory steps of sharing ideas, decision-making, and planning, procession, evaluation, and mutual benefit, for the project O. viverrini prevention and control (POPC). In-depth interviews were used for collection of need approaches to POPC. With 375 participants who completed the questionnaire, it was found that people had a high level regarding to participate in the POPC, particularly in the process stage ($\bar{X}=3.78$, S.D. = 0.56), but the lowest level was found in sharing ideas, decision making, and planning step ($\bar{X}=3.65$, S.D. = 0.63). By comparison, participant status and organization did not significantly differ with people participation. In each step, Ban Chaun sub-district had a high level of participation in the step of sharing ideas, decision making, and planning toward POPC, more than Bamnet Narong sub-district municipality (t=2.20, p=0.028). Approaches for POPC in Ban Chaun sub-district and Bamnet Narong sub-district municipality included requirements for budget support, annual campaigns for liver fluke prevention and control, campaign promotion, risk group observation, home visiting, community rules regarding reducing raw fish consumption in their communities, and a professional public health officer for working in their communities, BCSAO, BNSM, and SHPH, for O. viverrini prevention and control. This study indicates that people realize that eradication of the liver fluke needs a continuous people participation for O. viverrini prevention and control in their communities.

Objectives: The pathogenic Vibrios genus denotes halophilic bacteria that are distributed in aquatic environments, including both sea and freshwater. Vibrio cholerae, Vibrio vulnificus, and Vibrio parahaemolyticus are the most important species since they can be potent human pathogens and leading causes of septicemia, wound infections, and seafood borne gastroenteritis. The recent emergence of a potential pandemic clone, V. cholera serotype O1 and the cholera outbreak in South Korea in 2016 indicates the importance of consistent surveillance of pathogenic Vibrio genus within coastal areas. Methods: The present study was undertaken to determine where and how vibrios live in the aquatic environment adjacent to coastal areas of South Korea. For this survey, a total of 838 samples were obtained at 35 different sites in South Korean coastal areas during the period from January 2016 to December 2016. Pathogenic vibrios was determined using the real-time PCR method, and its clones were isolated using three selective plating media. We also monitored changes in seawater and atmospheric temperature, salinity, turbidity, and hydrogen ion concentration at the collection points. Results: The total isolation rates of V. vulnificus, V. cholera (non-pathogenic, non-O1, non-O139 serogroups), and V. parahaemolyticus from seawater specimens in 2016 were 14.2, 13.48, and 67.06%, respectively. Conclusions: The isolation rates of pathogenic vibrios genus showed a positive correlation with temperature of seawater and atmosphere but were negatively correlated with salinity and turbidity.

Pentatrichomonas hominis is considered a commensal protozoan in the large intestine of a number of mammalian hosts, such as cats, dogs, and non-human primates. The resulting infections, which can induce diarrhea, have been attributed to opportunistic overgrowth of P. hominis. This study was performed to confirm the P. hominis infection and its molecular characterization from the feces of puppies with diarrhea. Fecal samples were obtained from 14 German shepherd puppies with diarrhea over 1 week (7 females and 7 males, 2-9 months of age) residing on a dog farm in August 2007. Species-specific PCR assay identified P. hominis 18S rRNA genes in 3 of the 14 puppies (1 female and 2 males; 1 aged 2 months and 2 aged 9 months). This phylogenetic analysis established that P. hominis belonged to the 1st clade, which is comprised of Bos taurus and Felines.
