Purpose: The purpose of this study was to investigate the effect of a pathogenic bacteria filtration instrument for infection prevention during mouth-to-mouth ventilation. Methods: Two kinds of face shields were used for the study. One rescuer blew the filter through a bag valve mask and the filter was then cultured for bacteria. The mask was tested both on the front and back side. Results: Two kinds of face shields including the KF shield and CM shield were tested. The KF shield has received national certification and it prevented transmission of bacterial infection but the CM shield showed the opposite result and did not prevent bacterial transmission. Pathogenic bacteria were found on the back of the CM shield. Conclusion: A certified face shield is very important to prevent bacterial transmission. Face shields should be demonstrated and used by paramedic students.

Purpose - This study aimed to understand the influence of visible factors directly shown to and experienced by consumers such as physical evidence, and invisible factors obtained through acquaintances or other experienced consumers such as word-of-mouth, in the discount stores' marketing communication on impulse buying intention and store loyalty. Research Design, Data, and Methodology - This study examined the effect of factors in discount stores' marketing communication, for instance, physical evidence, word-of-mouth, and buying impulse intention. The questionnaire survey resulted in 68 completed questionnaires. Results - Physical evidence and word-of-mouth have a statistically significant positive effect on store loyalty. The results of regression analysis regarding whether visible or invisible factors have more impact showed that word-of-mouth has a statistically significant positive effect on store loyalty. With regard to impulse buying intention, only word-of-mouth was statistically significant. Conclusion These results suggested that visible and invisible factors that appeal to customers are very important. In particular, the results suggested that stores should create invisible factors (e.g., positive word-of-mouth) for their customers.

This study analyzes what effects does restaurant's well-being attribute selection have on word-of-mouth intention. Based on the result, this study aims to provide basic data for establishing Korean restaurant's service strategy and marketing strategy. The researchers surveyed 350 customers who visited a Korean restaurant located in Kangbook, Seoul. We encoded gathered data and analyzed them using SPSS 17.0 statistics package program. Following are the analyzed results. First, under hypothesis 1 - Korean restaurant's well-being attribute selection will have a positive influence on re-visitation intention - it is shown that sufficiency, healthiness, and steadiness have similar influence on re-visitation intention. Second, under hypothesis 2 - Korean restaurant's well-being attribute selection will have a positive influence on word-of-mouth intention - it is shown that sufficiency, healthiness, environment, and steadiness have similar influence on word -of-mouth intention. Third, under hypothesis 3 - Korean restaurant's re-visitation intention will have a positive influence on word -of-mouth intention - it is considered that eliciting customer's re-visitation intention also has influence on word-of-mouth intention. We will be necessary to consult how to derive customer's re-visitation intention or word-of-mouth intention by considering factors which customers of traditional Korean restaurant value.

Purpose: The aim of this study was to evaluate the effects of active mandibular exercise (AME) in patients with limited mouth opening after maxillomandibular fixation (MMF) release. Methods: The study used a quasi-experimental, nonequivalent control group and a pre test-post test design. Sixty-two patients with Maxillomandibular Fixation Release were assigned to the experimental (n=31) or control group (n=31). The AME was performed in the experimental group for 4 weeks. The exercise AME consisted of maximal mouth opening, lateral excursion and protrusive movement. These movements were repeated ten times a day. After the final exercise of the day, the number of tongue blades used for mouth opening was noted. The effect of AME was evaluated after MMF release at different time intervals: a) immediately, b) after 1 week, c) after 2 weeks, d) after 4 weeks, and e) after 12 weeks. The exercise was assessed using the following criteria: a) mandibular movements, b) pain scores associated with maximal mouth opening, c) discomfort scores associated with range of movement, and d) daily life activities that involve opening the mouth. Results: The experimental group showed significant improvement regarding the range of mandibular movements (maximal mouth opening (F=23.60, p<.001), lateral excursion to the right side (F=5.25, p=.002), lateral excursion to the left side (F=5.97, p=.001), protrusive movement (F=5.51, p=.001)), pain score (F=39.59, p<.001), discomfort score (F=9.38, p<.001). Daily life activities that involve opening the mouth were more favorable compared to those in the control group. Conclusion: The AME in patients after MMF release is helpful for increasing mandibular movement range, decreasing pain and discomfort, and improving day life activities that involve opening the mouth. Therefore, AME is highly recommended as an effective nursing intervention.

This study analyzed the outcome of 120 persons who used mobile game in order to investigate the influence that heuristic type which affects users' selection has on word of mouth, the influence that word of mouth has on users' behavioral intention and whether word of mouth will play the role of mediation between heuristic type and behavioral intention or not. First, heuristic(representatives, adjustment) type is found to have positive(+) influence on word of mouth (favorableness, reliance, persuasiveness). Second, while reliance word of mouth is found to have significant influence on behavioral intention, favorableness, persuasiveness and word of mouth is not found to have significant influence on behavioral intention. Third, heuristic (representative, adjustment) type is found to have significant influence on behavioral intention. Fourth, only reliance, word of mouth is found to play the role of mediation in the role of heuristic type and behavioral intention. The outcome of this study will help to understand users' behavioral intention selecting game in mobile game market.

The purpose of this study was to examine the effects of banking service quality on consumer satisfaction and positive word-of-mouth. A total of 330 bank consumers were investigated between Sept. 11 and Oct. 11, 2006. After sorting through the data, the responses of 299 consumer ( > 24 yrs old) were used for analysis. SERVPERF, the performance component of the Service Quality scale (SERVQUAL), was used to measure the four dimensions of reliability, responsiveness/empathy, assurance, and tangibles. Responses were partitioned by age and gender. The major findings were as follows; The effect of service quality by SERVPERF on consumer satisfaction and positive word-of-mouth did not differ according to gender. However, positive recommendation in males was directy related to the technical quality evaluate. In females, higher the functional quality evaluate was directly related to higher positive word-of-mouth recommendation. The effect of service quality by SERVPERF on consumer satisfaction was not revealed differently according to age. However, with respect to respondents under the age of 45, tangibles and assurance had a positive relationship with word-of-mouth recommendation. Furthermore, the higher the functional quality evaluate, the higher the level of positive word-of-mouth. Responsiveness/empathy was the most significant factor on positive word-of-mouth recommendation in respondents over the age of 45. In this age group, the higher the technical quality evaluate, the higher the level of positive word-of-mouth recommendation. These results have implications for banking service managers, particularly in improving service quality to increase consumer satisfaction and positive word-of-mouth. Future research is needed to replicate this study using more broad and representative samples in order to test the generalization of these findings.

Objectives : This study was to investigate the use of mouth-guards and maxillofacial injuries and to examined the relationship among variables in athletes group. Methods : The subjects were 459(86.5%), who were 18 years or older with mean age of 20.7 years. Data was collected using a self administrated questionnaire from May 25 to June 15, 2009. We surveyed maxillofacial injuries(temporo-mandibular disorders contained) and mouth-guards usage and confidence concerning mouth-guards in athletes. The data were analysed with chi-square analysis, fisher's exact test and logistic regression using the SPSS 15.0 windows. Results : Prevalence of body or maxillofacial injuries experiences was 54.5% for athletes and 47.1% for non-athletes groups(p>0.05). The other hand, the incidence temporo-mandibular disorders was 67.0% for athletes and 49.8% for non-athletes groups(p<0.05). The experience of the use of mouth-guards was 83.3% for athletes and 78.8% for non-athletes, there were not significant differences between athletes and non-athletes groups (p>0.05). Risk factors found to be significantly related to the occurrence of maxillofacial injury were: unused mouth-guards(OR=2.83), no rules for use of mouth-guards(OR=2.46). Conclusions : Based on the findings, maxillofacial injuries experience is highly associated with mouth-guards usage, not only athletes also general people should be educated on the use of mouth-guard in order to reduce the incidence of maxillofacial injuries.

This study is aimed to prepare the effective detail survey methods(Phase II) of abandoned metal mines through the contamination assessment for mine types and facilities in the abandoned metal mine areas. The study sites of 12 abandoned mines are located in Gyeonggi-do and Gangwon-do and those were chosen among 310 sites that the Phase II survey was conducted from 2007 to 2009 after considering the results of Phase I for abandoned mines scattered all over the country. 12 study sites were classified into four types; Type I sites only have pit mouth. Type II sites have pit mouth and mine-waste field. Type III sites have pit mouth and tailing sorting field. Type IV sites have pit mouth, tailing sorting field and concentrator(s). In forest land, paddy soil and farm land of Type I, As and Cd were showed average concentration, and Cu and Pb were high on the pit mouth area in one mines where the pit mouth was developed within 500 m. In the mines of Type II, Cu and Pb were showed average concentration too, but As and Cd were slightly high in pit mouth and mine-waste field. The mines of Type III which had grinding particle process through physical separation milling or hitting showed similar tendency with Type II. However, mines of Type IV pit mouth, mine-waste field and showed various results depending on defining the contamination sources. For example, if contamination source was pit mouth, the mixed results of Type I, II, II were showed. In tailing sorting field which was regarded as the most important source and having high mobility, however, if there were no facilities or it was difficult to access directly, field sampling was missed occasionally during phase I and phase II survey. For that reason, the assessment for tailing sorting field is missed and it leads to completely different results. In the areas of Type I mines, the concentration of heavy metals exceeded precautionary standards of soil contamination or not within 1,000 meters of pit mouth. Nickel(Ni) was the largest factor of the heavy metal contamination in this type. The heavy metals except Arsenic(As) were shown high levels of concentration in Type II areas, where pit mouth and mine-waste field were operated for making powder in upriver region; therefore, to the areas in the vicinity of midstream and downstream, the high content of heavy metals were shown. The tendency of high level of heavy metals and toxic materials contained in flotation agent used during sorting process were found in soil around sorting and tailing field. In the abandoned-pit-mouth area, drygrinding area and tailing sorting field area, the content of Cupper(Cu) and Zinc(Zn) were higher than other areas. Also, the contaminated area were larger than mine reclamation area(2,000 m) and the location of tailing sorting field was one of the important factors to estimate contaminated area.

This research aims to investigate into company workers' general characteristics and their awareness of the hygiene of the mouth and practice of it, in order to prepare schemes to improve the hygiene of their mouth. The findings of the research are listed in the following: First, the workers have a high level of awareness of the effect of tooth-brushing to prevent periodontal diseases but a low degree of awareness of its effect to prevent decayed teeth and of the necessity of mouth hygienic supplies. Second, they have a high level of awareness of the necessity and importance of scaling, but most of them do not have their teeth scaled periodically. To repeat, they have a high level of awareness of the necessity of dental examination, but not many of them put such awareness of theirs into practice. Third, married workers have a higher level of awareness of the hygiene of their mouth than unmarried ones do. The higher concern they have about the hygiene of their mouth, the more awareness they have of the hygiene of their mouth. Fourth, the higher monthly average income they have, the more frequently they put into practice their awareness of the hygiene of their mouth. And the poorer hygiene of their mouth they have, the more strongly they put into practice their awareness of the hygiene of their mouth.

Maximum mouth opening is regarded as an important tool used to evaluate the clinical function of temporomandibular joint and the masticatory system. It has been reported that children can also exhibit severe dysfunction or pain in some cases of temporomandibular disorder. The purpose of this study was to measure the normal maximum mouth opening in Korean children and to analyze the correlations between mouth opening and the associated factors. Maximum mouth opening was measured from 151 healthy children between the ages of 2 and 6 years old. Age, height, weight, and mouth width were also recorded. As a result, the mean maximum mouth-opening was $37.72{\pm}5.10mm$. While the values were greater in boys than in girls without statistical significance, the increases of maximum mouth opening based on age, height, weight, and mouth width were significant (p < 0.05). In children, positive correlation coefficients were observed between maximum mouth opening and the associated factors and height showed the highest correlation. In conclusion, we collected data of the normal range of maximum mouth opening in Korean children, and this study can be utilized as a basis in diagnosing pediatric temporomandibular disorder and safety standard of mouth opening during dental procedures.
