Objectives: The purpose of the study is to investigate the correlation with subjective oral health status and food preference in elderly people. Methods: Data were extracted from the fifth Korea National Health and Nutrition Survey 2010-2012. The survey data included general characteristics of the subjects, food preference, and subjective oral health status. Food preference was analyzed by assigning score to 63 food categories. The subjective oral health status consisted of toothache within a month, self-perception of oral health, chewing difficulty, mastication difficulty, and speaking difficulty. Data were analyzed by frequency analysis, descriptive statistics, ${\chi}^2$ test, t-test, and ANOVA using SPSS 22.0 program. Results: Elderly men had a tendency to have a liking for all food categories except for fruit. Difficulty in chewing and mastication was shown in those who had older age, lower education, lower monthly income, and national basic livelihood security. Difficulty in speaking was found in those who had older age, lower education, and national basic livelihood security. Self perception of oral health status was closely related to food preference for pulses and potatoes, fish, vegetables and others(p<0.05). Difficulties in chewing and mastication had relation to all food categories excepting cereals, lipids and sugars(p<0.05). Speaking difficulty were significantly different in pulses, potatoes, meat, eggs, vegetables, fruits, milk, dairy products, and others(p<0.05). Conclusions: Poor subjective oral health status was closely related to food preference. It is necessary to educate that maintenance of good oral health is to ingest the balanced nutrition in the elderly people.

The objectives of this study are to research the frequency of depression symptom in patients with voice disorders and to investigate parameters associated with depression from voice evaluation. A hundred ninety six patients(106 males and 90 females) who had been diagnosed with voice disorders first in their lifetime were selected. All the patients were examined by laryngeal stroboscopy. For depression and voice study, personal interview, acoustic and aerodynamic analysis, voice handicap index(VHI), reflux symptom index(RSI), and beck depression index(BDI) were done respectively. Mild to severe BDI were seen in 26.2%(52 patients) of the whole patients. A BDI mean score of female patients was $8.8{\pm}7.5$ which was higher than that of male patients($5.6{\pm}6.6$), the difference observed being statistically significant(p<0.001). In the acoustic analysis, the score of sent_duration parameter was increasing in the patients with depression, which was significantly higher than the score of the patients without depression(p<0.05). In the addition, the scores of VHI and RSI were higher in the patients with depression(p<0.001). Our findings suggest that the prevalence of depression in patients with voice disorders is related to female, speaking velocity, and self-questionnaire. This result can be used for psychologically based approach to therapy.

Objectives: This study aims to contribute to the prevention of dental diseases and health care in the elderly by investigating the relationship among the experiences of chronic diseases, dental health status, and the behaviors in the Korean elderly people. Methods: A total of 2,856 elderly people aged 65 or older were selected as the final analysis subjects using data from the 6th National Health and Nutrition Examination Survey (2013-2014). Chronic diseases were defined as 'cardiocerebrovascular diseases', 'diabetes', 'chronic respiratory diseases', and 'cancer' diagnosed by the doctors. For the statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the relationship among the experiences of chronic diseases, general characteristics, dental health status, and the behaviors in the Korean elderly. Finally, logistic regression analysis was performed to investigate the relationship among the experiences of chronic diseases, dental health status, and the behaviors. Results:The prevalence of Cardiocerebrovascular diseases was significantly higher in the 3-4 group of community periodontal index with the score of 1.36 (95% CI 1.03-1.00) than in the 0-2 group. The prevalence of Cardiocerebrovascular diseases was significantly higher in the group without dental examination during the past one year with the score of 1.29 (95% CI 1.00-1.66). The prevalence of diabetes was significantly higher in the uncomfortable speaking state group with the score 1.46 (95% CI 1.12-1.91). The prevalence of cancer was significantly higher in the partial denture needs group with the score 1.67 (95% CI 0.98-2.83). Conclusions: Regular dental examinations and dental health care for the elderly with chronic diseases showed that periodontal health and residual teeth could be maintained and managed. Therefore, continuous customized dental health services should be implemented for the elderly with chronic diseases.

Purpose: Polycystic Ovary Syndrome Questionnaire (PCOSQ) was developed to measure health-related quality of life of women who had polycystic ovary syndrome. The purpose of this study was to exam reliability and validity of the Korean version of PCOSQ. Methods: A sample of 101 women who had polycystic ovarian syndrome was recruited from outpatient gynecology clinics. Factor analysis was carried out to verify the composition of dimensions of the Korean version of PCOSQ. Concurrent validity was examined by assessing the correlation between the PCOSQ and health related quality of life, and convergent validity was evaluated by testing correlation between PCOSQ and depression. Reliability was assessed using Cronbach's ${\alpha}$. Results: The content validitywas satisfactory (CVI=0.85). Factor analysis identified 5 factors, and factor loadings of the PCOSQ ranged from .48 to .90. Correlation was found between the PCOSQ and health related quality of life (Physical component score: r=.33, p=.001; Mental component score: r=.44, p<.001) and between the PCOSQand depression (r=-.36, p<.001). The Cronbach's ${\alpha}$ of the PCOSQ was .93, indicating reliable reliability. Conclusion: These results demonstrate that the Korean version of PCOSQ is a reliable and valid instrument for evaluating Korean-speaking women with polycystic ovarian syndrome.

The past decade has witnessed the abundant use of computer in testing language skills such as listening and reading. Compared with these language skills, we have experienced little use of computer in testing a speaking skill including pronunciation. This is largely due to limitations of the current computer technology. One of such limitations for testing pronunciation is to store and automatically evaluate what the learner utters. Due to this limitation, the computer simply stores what the learner utters and raters evaluate it afterward on a certain rating continuum. With the advent of voice recognition technology, however, the computer has been able to test pronunciation in a systematic way. This technology enables the computer to identify, visually show, and evaluate the learner's intonation pattern by means of autocorrection. The evaluation is expressed in terms of the degree in which the learner's intonation pattern overlaps with that of the native speaker of the target language. In particular, the degree is numerically displayed on the screen, and this numeral is considered as the score of the learner's utterance under our testing framework.

The objective of this study was to evaluate Environmental microbiology (EM) as a basic course for the environmental engineering program of Korea Maritime University which has been accredited by Accreditation Board for Engineering Education of Korea (ABEEK). Evaluation result of the lecture objectives was more than the average (3.5/5.0). The overall score for learning achievement assessment was more than average level of learning achievement (3.4/5.0). Interestingly, engineering design implementation regarding a specific topic as an extensive learning process has proven to be more effective (3.5/5.0). Some of effective class improvement strategies suggested were to encourage students to participate in the class with self-motivation and accountability: preview and review of the lecture, team presentation in English-speaking settings, and submitting project report written in English. In the future class of EM, test and evaluation of application capability of EM and environmental biotechnology (EB) theories to engineering problem solving should be emphasized.

By evaluating the health status by Cornell Medical Index in conjunction with their academic grade, we attempted to find out whether any health condition may affect on their academic carrier. CMI health questionnaire was filled out by student and matched with one's own academic score if the previous year. Academic score was classified into 5 grades: excellent, very good, good, fair and poor. Difference in number of questions between sections was corrected by standard score method with means of 50 and standard deviation of 10. Differences in number of 'yes' answers between sections and between groups of students in each grade were statistically tested by two-way variance analysis method. On the other hand, influence of neuropsychiatric factors (section M-R) on the academic carrier was analyzed by $X^2-test$ with Fukamachi's classification. The following were the results obtained in this study: 1) Number of 'yes' answers in sections related to mood and feeling patterns (sections M-R) were appeared to be influential to academic carrier in male students, but not in female students. 2) Generally speaking, in groups of higher academic grade, number of 'yes' answers in each section was on an averege 50 or less, and in groups of lower academic grade, the number was 50 or more depending on sections. 3) Number of 'yes' answers between sections and between groups in each academic grade were significantly different both in male and female college students. 4) It was noteworthy that data obtained from CMI questionnaire might be variable subjectively by examinees with some factors at the time of administration.

The purpose of this study was to obtain normative nasalance scores for adult subjects speaking the Korean language and to determine whether significantly different scores exist for female and male speakers. Mean nasalance scores were obtained for normal speaking Korean adults while they are reading vowels, consonants, no nasal sentence, mild nasal sentence, and high nasal sentence. Thirty adults who had lived in Seoul area with normal articulation, resonance, and voice were included. Among the subjects 15 were male aged 24-38 years and 15 were female aged 19-33. Nasometer data were collected and analyzed using the Kay Nasometer 6400. Nasalance scores were evaluated to investigate the effect of gender by using statistical tests. Nasalance data showed that nasalance values varied accroding to speech stimuli, and there was no significant difference in nasalance scores between male and female speakers in most of the language samples.

Purpose: The aim of this study is to investigate the quality of basic life support (BLS) information for primary Korean-speaking individuals on the internet. Methods: Using the $Google^{(C)}$ search engine, we searched for the terms 'CPR', 'cardiopulmonary resuscitation (in Korean)' and 'cardiac arrest (in Korean)'. The accuracy, reliability and accessibility of web pages was evaluated based on the 2015 American heart association(AHA) guidelines for CPR & emergency cardiovascular care, the health on the net foundation code of conduct and Korean web content accessibility guidelines 2.1, respectively. Results: Of the 178 web pages screened, 50 met criteria for inclusion. The overall quality of BLS information was not enough (median 5/7, IQR 4.75-6). 23(36%) pages were created in accordance with 2010 AHA guidelines. Only 24(48%) web pages educated on how to use the automated electrical defibrillator. The attribution and transparency of the reliability of pages was relatively low, 20(40%) and 16(32%). The web accessibility score was relatively high. Conclusion: A small of proportion of internet web pages searched by Google have high quality BLS information for a Korean-speaking population. Web pages based on past guideline were still being searched. The notation of the source of CPR information and the transparency of the author should be improved. The verification and evaluation of the quality of BLS information exposed to the Internet are continuously needed.
