The objective of this study was to examine two new parameters by which we could screen people with malignant vocal folds. The new parameters were the difference sums and Pearson correlation coefficients between adjacent pairs of intensity level matrices of narrow-band spectra. Audio files from the Korean Disordered Speech Database were analyzed by Praat, a speech analysis software, to obtain matrices of 400 intensity levels at 16 time points of each sustained vowel spectra. We limited our study to 12 normal subjects and 20 patients with malignant vocal folds who recorded at least three Korean vowels at a sound-proofed booth in Busan National University Hospital. Results indicated that the average coefficients of the abnormal subjects were much lower than those of the normal subjects while the average difference sums of the patients were much higher than those of the normal ones. Also, we found that the degree of the malignancy of the vocal folds was related to the coefficients and sums. However, some subjects at the initial stages of cancerous vocal folds yielded almost comparable coefficients and difference sums to those of the normal speakers. Further studies on larger databases will be desirable to set certain criteria or threshold levels for screening people with vocal fold diseases.

Discourse is regarded as an important component of communication assessment, but studies about the discourse characteristics of the elderly are scant. The purpose of this study was to confirm the effects of aging, gender, and educational level on discourse in elderly people with normal cognitive function. Forty normal elderly and forty young people participated in this study. A picture description task (Boston Cookie-Theft picture) was used to examine discourse function. The description task was analyzed for both productivity (total number of sentences, total number of syllables, and syllables per sentence) and semantics (CIU ratio). The results were as follows: 1) Only CIU ratio differed significantly according to age. 2) In the total number of syllables and syllables per sentence, females demonstrate a higher number than males. 3) The CIU ratio differed significantly according to educational level. These results suggest that impairment of communicative function is an aspect of cognitive impairment that can be related to aging. Also, discourse performance in the elderly is associated with their gender and educational level.

In the case of a hearing impaired person using sign language, there are many difficulties in communicating with a normal person who does not understand sign language. The sign language translation system is a system that enables communication between the hearing impaired person using sign language and the normal person who does not understand sign language in this situation. Previous studies on sign language translation systems for communication between normal people and hearing impaired people using sign language are classified into two types using video image system and shape input device. However, the existing sign language translation system does not solve such difficulties due to some problems. Existing sign language translation systems have some problems that they do not recognize various sign language expressions of sign language users and require special devices. Therefore, in this paper, a sign language translation system using an artificial neural network is devised to overcome the problems of the existing system.

At old age, as people depend on superficial clues when they interpret the overall context of communication, their ability to understand connotative and figurative words and articles could deteriorate. In this study, 50 normal young(junior) people and normal old(senior) people were made to perform a task to understand similes, metaphors, idioms, and proverbs, the sub-areas of figurative language. For the task, participants were made to understand a paragraph consisting of several sentences and select a correct answer representing appropriate figurative language. As a result of the analysis, first, old people showed a lower level of performance than young people in all the sub-areas of figurative language. Second, in understanding idiomatic words and proverbs, old people showed a lower level of performance due to unfamiliarity. Third, for the types of wrong answers, old people mostly understood only the literal meanings in all the sub-areas of figurative language. Due to aging, old people come to have a lowered level of the pragmatic language ability, reasoning ability, and inhibiting ability to efficiently communicate with others considering certain situations and contexts. Thus, old people could have difficulties in understanding inner meanings from others in daily communication.

Background: To analyze the expression of estrogen receptors (ER), progesterone receptors (PR), C-erbB-2 and Ki-67 in endometrial carcinoma (EC) and their relationships with the clinicopathological features. Materials and Methods: Sixty-seven EC samples, 53 normal endometrial samples and 53 atypical hyperplasia endometrial samples were all selected in Shaanxi Provincial People's Hospital from Jun., 2012 to Jun., 2014. The expression of ER, PR, C-erbB-2 and Ki-67 in EC tissue, normal endometrial tissue and atypical hyperplasia endometrial tissue was respectively detected using immunohistochemical SP method. The relationships between the expression of ER, PR, C-erbB-2 and Ki-67 and the patients' clinicopathological features as well as their correlations in EC tissue were also analyzed. Results: The positive expression rates of ER and PR in EC tissue were 44.8% and 41.8%, respectively, dramatically lower than in atypical hyperplasia endometrial tissue and normal endometrial tissue (P<0.01). The positive expression rates of C-erbB-2 and Ki-67 in EC tissue were 80.6% and 64.2%, respectively, significantly higher than in atypical hyperplasia endometrial tissue and normal endometrial tissue (P<0.01). In EC tissue, the expression of ER and PR was closely associated with the differentiated degrees and depth of myometrial invasion (P<0.05), while that of C-erbB-2 and Ki-67 with the clinical staging, differentiated degrees, depth of myometrial invasion and presence or absence of lymph node metastasis (P<0.05). Spearman correlation analysis further displayed that the expression of ER was positively correlated with PR (r=0.393, P=0.001), but negatively with C-erbB-2 and Ki-67 (r=-0.469, P=0.000; r=-0.329, P=0.007); The expression of PR was negatively correlated with C-erbB-2 and Ki-67 (r=-0.273, P=0.025; r=-0.251, P=0.041), but that of C-erbB-2 positively with Ki-67 (r=0.342, P=0.005). Conclusions: Abnormal expression of ER, PR, C-erbB2 and Ki-67 might play an important role in endometrial malignant transformation and cell differentiation, so their joint detection is likely to be a comprehensive combination of immune factors, which is of great importance for EC prognosis.

Purpose: The purpose of this study was to identify the factors that affect depression among elderly people with, and without, dementia. Method: The participants were 903 people who were 65 or older and resided in Sungnam City. Data were collected from April to July 2002 using a questionnaire. The collected data were analyzed using descriptive statistics and hierarchical multiple regression aided by SPSS/PC. Result: The variables at the final step of the regression equation accounted for 28.2% of variance in the dementia group, 21.4% in the group with suspicious dementia, and 18.9% in the normal group. The multiple regression analysis revealed that ADL and instrumental support were related significantly to depression in the dementia group. Self-rated health, IADL, social activity support, and instrumental support were significantly related to depression in the group with suspicious dementia. In the normal group, education, self-rated health, and living arrangement with family were significantly related to depression. Conclusion: Social support and health condition are important to decrease depression in elderly people with dementia.

Objectives: The purpose of the study is to investigate the relationship between obesity and periodontal diseases in adults. Methods: The subjects were 6,762 adults over 19 years old selected from the 6th Korean National Health and Nutrition Examination Survey (2013). The study instruments included periodontal status of periodontal diseases, body mass index (BMI), and waist circumference (WC). Periodontal status was evaluated by community periodontal index (CPI). Data were analyzed using SPSS 18.0 program. Results: The prevalence of periodontal diseases was higher in male, older aged people, undereducated people, current smokers, and those having poor cognition for toothbrushing (p<0.001). The rate of obesity by BMI and WC was higher in male, older aged people and current smokers. The rate of obesity was lower in well-educated people and good practice of toothbrushing (p<0.001). The prevalence of periodontal diseases by BMI showed 0.565 times lower in underweight population, 1.302 times higher in overweight population, and 1.311 times higher in highly obese population than normal population. The prevalence of periodontal diseases by waist circumferences showed 1.404 times higher in obese population than the normal population (p<0.05). Conclusions: It is very important to promote periodontal disease prevention and education for obese population in Korea. The risk of periodontal diseases can be preventable by decrease of BMI and WC.

Along with the increasing number of disabled people, number of handicapped people who spends most of their time indoors increase. Their disabilities constrain them in social activities and bind them to indoors. But living environment built for normal people are many cases inevitably inconvenient for disabled people. People realizes that housing renovation is necessary, however problems such as financial difficulties must be solved in advance. House renovations, to create comfortable and independent living conditions for disabled people, various thesis and documents were analyzed, along with survey through questionnaire. Results are as following. (1) House renovation is necessary, due to the increasing number of disabled people and inconvenience of former house form. (2) Integrated or specialized house renovation manual is required to satisfy the different need derived from extent and type of disabilities. (3) Central and local government's policy for continued support is necessary. (4) House renovation plan for homeless disabled people is necessary. (5) Separate research on the size of space, type of space, efficiency is necessary. (6) Separate house renovation plan considering the people who lives with disabled people is required. (7) Disabilities are not personal but societal problem. This paper is to uncover all the problems in the house renovation for disabled people. It will be used to develop house renovation manual in the future. Therefore, this paper does not deal with the actual house renovation plans.
