Background Many people have an interest in the correction of facial scars or deformities caused by trauma. The increasing ability to correct such flaws has been one of the reasons for the increase in the popularity of facial plastic surgery. In addition to its roles in communication, breathing, eating, olfaction and vision, the appearance of the face also plays an important role in human interactions, including during social activities. However, studies on the importance of the functional role of facial appearance. As a function of the face are scare. Therefore, in the present study, we evaluated the importance of the functions of the face in Korea. Methods We conducted an online panel survey of 300 participants (age range, 20-70 years). Each respondent was administered the demographic data form, Facial Function Assessment Scale, Rosenberg Self-Esteem Scale, and standard gamble questionnaires. Results In the evaluation on the importance of facial functions, a normal appearance was considered as important as communication, breathing, speech, and vision. Of the 300 participants, 85% stated that a normal appearance is important in social activities. Conclusions The results of this survey involving a cross-section of the Korean population indicated that a normal appearance was considered one of the principal facial functions. A normal appearance was considered more important than the functions of olfaction and expression. Moreover, a normal appearance was determined to be an important facial function for leading a normal life in Korea.

This presentation explores on the perceptual characteristics of the lateral sound /l/ in CV syllables. At initial position we found that /l/ has well marked formant transitions. Then several questions arise: 1) are these formant structures dependent on the following vowel\ulcorner. 2) Are the formant transitions giving an additional cue for the identification\ulcorner Considering that the French vocalic system presents a greater variety of vowels than Spanish, several experiments were designed to verify to what extent a more extensive range of vocalic timbres contribute to the perception of /l/. Natural emissions of /l/ produced in Argentine Spanish and Canadian French CV syllables were recorded, where V was successively /i, e, a, o, u/ for Spanish and /i, e, $\varepsilon$, a, $\alpha$, o, u, y, \phi$/ for French. For each item, the segment C was maintained and V was replaced by cutting & splicing by each of the remaining vowels without transitions. Results of the identification tests for Spanish show that natural /l/ segments with low Fl and high formants F3, F4 can be clearly identified in the /i, e, u/ vowel contexts without transitions. For French subjects the combination of /l/ with a vowel without transitions reflected correct identifications for its own original vowel context in /e, $\varepsilon$, y, $\phi$/. For both languages, in all these combinations, F1 values remained rather steady along the syllable. In the case of /o, u/ very likely the F2 difference lead to a variety of perceptions of the original /l/. For example in Ilul, French subjects reported some identifications of /l/ as a vowel, mainly /y/. Our observations reinforce the importance of F1 as a relevant cue for /l/, and the incidence of the relative distance between formants frequencies of both components.

Accurate voice activity detection have a great impact on performance of speech applications including speech recognition, speech coding, and speech communication. In this paper, we propose methods for voice activity detection that can adapt to various car noise situations during driving. Existing voice activity detection used various method such as time energy, frequency energy, zero crossing rate, and spectral entropy that have a weak point of rapid. decline performance in noisy environments. In this paper, the approach is based on existing spectral entropy for VAD that we propose voice activity detection method using MFB(Met-frequency filter banks) spectral entropy, gradient FFT(Fast Fourier Transform) spectral entropy. and gradient MFB spectral entropy. FFT multiplied by Mel-scale is MFB and Mel-scale is non linear scale when human sound perception reflects characteristic of speech. Proposed MFB spectral entropy method clearly improve the ability to discriminate between speech and non-speech for various in noisy car environments that achieves 93.21% accuracy as a result of experiments. Compared to the spectral entropy method, the proposed voice activity detection gives an average improvement in the correct detection rate of more than 3.2%.

Purpose : The purpose of this study was that For high school students in Busan, in order to provide basic data in selecting dental hygienists by establishing the correct perception and image of dental hygienists by identifying the image of dentists and career doctors who will choose dental hygienists. Methods : The comparison of group differences with dental hygienists' images was analyzed with independent sample t-test and one-way ANOVA. Correlation between image factors of dental hygienists was analyzed using Pearson's correction coefficient. Results : The image for dental hygienists averaged 3.87 points overall, while the average for each area of the image was 4.09 points for professional images, 4.07 points for business images, 4.08 points for personal images and 3.28 points for social images. When choosing a career path, 18.8 percent said they would not consider dental hygiene, and if they said they would consider dental hygiene, both work, professional, personal and social images were significantly high (p<.05). Professional and professional images (r=.975, p<.05) in the correlation between factors of dental hygienist images, personal and professional images (r=.942, p<.05), social and professional images (r=.865, p<.05), business and personal images (r=.924, p<.05), business image and social image (r=.858, p<.05), personal and social images (r=.882, p<.05) expressed a statistically significant amount of correlation. Conclusion : The study found that high school students' image of dental hygienists was rather positive, but their social image was rather low, and most students did not consider dental hygiene. Therefore, specific measures will be needed to build a desirable image for dental hygienists and positively recognize dental hygienists with active promotion and career experience for dental hygienists in the future.
Objectives: Healthcare Accreditation Program in Korea started in 2011. The aim of this study is to contribute to the development of the Healthcare Accreditation Program in Korea by comparing the perception of the Healthcare Accreditation Program for the accredited hospitals and the surveyors. Methods: This study was performed targeting 77 accredited acute care hospitals and 245 surveyors who have surveyed acute care hospitals from 2010 to February 2014. They responded to our questionnaire via a survey website, and we analyzed the results. Results: We found that the hospitals rated the professionalism of surveyors more positively than surveyors. While average score of the hospitals was higher for 'The understanding of the accreditation standards and survey methods was correct' than that of the surveyors (p<0.01), average score of the surveyors was higher for 'Mediation and collaboration between surveyors were smooth' than that of the hospitals (p<0.05). And we found that the surveyors rated the Accreditation Program more positively than hospitals. While average score of the hospitals was higher for 'Surveyors have the professionalism' than that of the surveyors (p<0.05), average score of the surveyors was higher for 'It is easy to understand the accreditation standards and evaluation items' than that of the hospitals (p<0.01). Conclusion: In order to development of the accreditation program, it is necessary to strengthen the professionalism of surveyors and improve the acceptability of the accreditation program.
This study was carried out to investigate the dietary attitudes, nutrition knowledge, nutrient intake, eating-related characteristics of dancing major and non-major female university students. The survey was conducted from October 1 to November 10, 2003 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: 25.5% of the underweight group, 53.6% of the normal weight group, 12.5% of the overweight group and 66.7% of the obese group had correct perception about their body image. Eighty-one point three percent of the dancing majors and 77.2% of the non-majors were concerned about weight control, and 71.3% of the dancing majors and 64.5% of the non-majors had weight control experiences. There were no significant differences in nutrition knowledge scores and dietary attitude scores between dancing majors and non-majors. There were no significant differences in ‘predisposition to obesity scores’ between dancing majors and non-majors, and the scores were low. ‘Predisposition to anorexia’ scores and ‘uncontrollable urges to eat’ scores were significantly higher in the dancing majors compared to the non-majors. Intakes of the nutrients were lower than those of the Korean recommended dietary allowances (RDAs), except vitamin C in the dancing majors. Intakes of calories, calcium and iron were lower than those of the RDAs in the non-majors. Dietary attitude was positively correlated with nutrition knowledge but was negatively correlated with ‘uncont-rollable urges to eat’. In the dancing majors, ‘predisposition to obesity’ showed significantly positive correlation with obesity rate and ‘uncontrollable urges to eat’ and was negatively correlated with nutrition knowledge and dietary attitude. In the non-majors, obesity rate showed positive correlation with ‘predisposition to obesity’ and ‘uncontrollable urges to eat’. Therefore proper nutritional education program and recommended dietary allowances are required for dancing majors to improve their nutritional status.
Today, the field that actively utilizes HMD, which is a representative implementation device of virtual reality, is game. We have frequently used interface design using metaphor to user interface of HMD based virtual reality game. The purpose of this study is to find out the metaphor types that appear in the game interface of the virtual reality FPS genre of HMD devices, which is a new medium. As a result of research, the metaphor types appearing on multiple interfaces have navigation, predictability-based, familiarizing, and physical world metaphor in terms of information perception and predictability-based and familiarizing metaphor in term of control action. It is considered possible to construct a correct mental model. It is expected that the stability-based metaphor to prevent user mistakes and the presentation metaphor to identify the identity of information space will be needed in the future.
The purpose of this study was to implement and evaluate the health education program for elementary school children. The program consisted of nutritional education and physical exercise. The subjects composed of 89 school children, first through sixth grade (n = 100), who had completed ten weeks of health education program from April through July 2010. Pre-post intervention design was used to evaluate the program effectiveness. After completing health education program, the number of overweight subjects decreased (boys 13 to 11 and girls 11 to 9) and the number of obese subjects decreased from 5 to 4 for boys and 4 to 2 for girls The number of sit-ups significantly increased in both 1-2 grade girls and 3-4 grade girls. Backward trunk extension of 1-2 grade girls also significantly increased (p < 0.05). The level of serum total cholesterol decreased from 171.8 mg/dL to 153.5 mg/dL (p < 0.001). Hypercholesterolemia (above 239 mg/dL), hyperLDLcholesterolemia (above 175 mg/dL) and low level hemoglobin subjects changed to normal levels. Total score of nutrition knowledge increased from 5.9 to 6.1 (p < 0.05), percentage of perception answers increased significantly in 5 out of 10 items and percentage of correct answers increased significantly in 6 out of 10 items (p < 0.05). Three food habits improved, including, "having breakfast", "having diverse foods" and "having vegetables per meal" (p < 0.05). Two self-efficacy items improved significantly, including, "having meals slowly", "having exercise instead of watching TV or computer" (p < 0.05). These results suggest that health education program for elementary school children including nutritional education and physical exercise may be effective to improve their anthropometric characteristics, physical fitness, hyperlipidemia, nutrition knowledge, food habits and self-efficacy.
Coronal/non-coronal asymmetry refers to the typological trend wherein coronals rather than non-coronals are more likely targets in place assimilation. Although the phenomenon has been accounted for by resorting to the notion of unmarkedness in formalistic approaches to sound patterns, the examination of rules and representations cannot answer why there should be such a process in the first place. Furthermore, the motivation of coronal/non-coronal asymmetry has remained controversial to date even in the field of phonetics. The present study investigated the listeners' perception of coronal and non-coronal stops in the context of $VC_{1}C_{2}V$ after critically reviewing the three types of phonetic accounts for coronal/non-coronal asymmetry, i.e., articulatory, perceptual, and gestural overlap accounts. An experiment was conducted to test whether the phenomenon in question may occur, given the listeners' lack of perceptual ability to identify weaker place cues in VC transitions as argued by Ohala (1990), i.e., coronals have weak place cues that cause listeners' misperception. 5pliced nonsense $VC_{1}C_{2}V$ utterances were given to 20 native speakers of English and Korean. Data analysis showed that majority of the subjects reported $C_{2}\;as\;C_{1}$. More importantly, the place of articulation of C1 did not affect the listeners' identification. Compared to non-coronals, coronals did not show a significantly lower rate of correct identifications. This study challenges the view that coronal/non-coronal asymmetry is attributable to the weak place cues of coronals, providing evidence that CV cues are more perceptually salient than VC cues. While perceptual saliency account may explain the frequent occurrence of regressive assimilation across languages, it cannot be extended to coronal/non-coronal asymmetry.

In this paper, a single house fire alarm device, which can solve the problem of fire perception at midnight time and the attenuation of alarm signal due to the wall between rooms based on the wireless communication, was developed. The radio controlled fire alarm device was designed to allow fire to be recognized quickly and accurately by monitoring the temperature and $CO_2$ concentration based on the temperature sensor and gas sensor, by detecting the fire in the house and by transmitting the fire alarm to the individual wireless alarms of other rooms using the wireless transmission/reception module. Using the Arduino as a main control device, three independent fire alarm device prototypes were made, and their usefulness was verified by the correct operations in temperature and gas tests.
