This study was surveyed the knowledge and attitude toward the elderly in dental personnels, who play an important role in oral health of the elderly in the aging society, In order to arrange the basic data that is conducive to development in the mouth care of the elderly, the research was conducted from January 7 to February 14, 2008, targeting 270 dental personnels in Daejeon & Chungnam area, who are in charge of oral duties in the current clinic. As a result of analyzing so that questionnaire can be prepared with the self-administered questionnaire, the following results were obtained 1. The knowledge level on the elderly in dental hygienist was 13.47 marks out of 25-mark perfection. There was no difference in knowledge depending on job category and volunteer-work activity experience, And, there was no difference even depending on physical & physiological sphere, psychological sphere, and family & social sphere. 2. The attitude level toward the elderly in dental hygienist was 91.63 marks out of 150-mark perfection. Dental hygienist showed positive attitude in personality characteristic, emotional characteristic, and self-management ability by sphere, and showed statistically significant difference (p=0.011). 3. In case of having volunteer-work activity experience, the attitude level toward the elderly was 92.57 marks out of 150-mark perfection, A case of having volunteer-work activity experience showed positive tendency in emotional characteristic, self-management ability, and judgement-ability characteristic by sphere, And, the attitude toward family relation was indicated to be negative tendency, thus there was statistical significance(p=0.022). 4. As for the correlation between knowledge and attitude toward the elderly, dental hygienist was indicated to have high interest in the volunteer-work experience, the elderly education experience, and the elderly problem(r=0. 444). The knowledge and attitude toward the elderly had slightly positive correlation(r=0.155). Dental hygienists are being required gradually as the primary staff for the elderly people's dental care in the aging society. A continuous education is needed so that dental hygienists can have positive sight in understanding, knowledge, and attitude. And, the development in a mouth care program for the elderly in line with it is considered to be necessary.

This study was designed to observe the nutritional knowledge, food behavior, nutritional attitudes and food preference of elderly living in home. Two hundred and thirty elderly were examined on questionnaire. The results of this study are summarized as follows. 1. The average score of their nutritional knowledge was 6.08 (the highest mark was 10.00). The nutrition knowledge score of the elderly live with spouse was higher than those live alone and goes up according to the education degree of elderly and pocket money. The correct answer ratio about a question of geriatric diseases was somewhat higher than another question. 2. The average score of their food behavior was 21.90(the highest mark was 33.00) and the score of the female was higher than that of the male and the college-educated elderly have the highest score. Generally their food behavior was improved by the increasing intake of animal protein and milk. 3. The average score of their nutritional attitude was 11.25 (the highest mark was 15.00) and those of 70~74 age old have the lowest score. And they answered that they are willing to change their food behavior for their health. In this study we expect that the authorities would operate the nutritional education for the prevention of degenerative diseases and the development of the food behavior at a public health center or another groups(no-in-jung) as a part of service for the welfare of elderly. 4. They prefered vegetable foods to animal foods and baking, broiling, and raw foods to the fried foods, and they liked the sweet foods, the fruits, milk and lactic acid beverage as snack or dessert.

Objectives : The aim is to examine what a selective factor of dental institution in the elderly is, which can be used as a strategy for vitalizing hospital management, and which difference there is in selection of dental institution according to health-promotion lifestyle. Methods : Questionnaire survey of individual interview was carried out targeting 177 old people in over 65 years old of Jeonju, Iksan, and Gunsan in Jeollabuk-do Province by convenience sampling from August 16, 2010 to August 27. The analysis was performed by using SPSS WIN 12.0 program. Results : 1. The average mark of health-promotion lifestyle in the elderly was 2.69 points. The health responsibility was the highest with 2.91 points. 2. The mark of health-promotion lifestyle was higher in the higher educational level of the elderly(p<0.01), when monthly income is more than 2 million won(p<0.01), and in the better subjective awareness of oral condition(p<0.01). 3. The group with high mark of health-promotion lifestyle regarded reliability(p<0.001), economic efficiency(p<0.01), and facilities & cleanliness(p<0.01) as important factors when selecting dental institution. Conclusions : The development and expansion in health-promotion program targeting the elderly are seen to be necessary that reflect difference by sphere in health-promotion lifestyle. There will be necessity for pursuing even a strategy for the elderly in the group who have relatively low characteristic in the practice level of health-promotion lifestyle. Also, given understanding characteristics on the elderly and focusing on management proper for the needs of medical consumers, the successful medical management is thought to be likely possible.

The purpose of this study was to the relationship between powerlessness, self-efficacy and quality of life in hemodialysis patients. The subjects were compromised of 198 hemodialysis patients from Pusan, Kyung-Sang Namdo and Kyung-Sang Bukdo 6 hemodialysis clinics. Data were collected by questionnaires from Sep. 19 to Oct. 27, 2001. The instrument used for study were the Powerlessness Behavioral Assessment Tool(Miller, 1983) and self-efficacy developed by Kim, Ju-Hyun(1995) and quality of life developed by Kim, Ok-Soo(1993). Collected data were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffe test, pearson correlation. The results were as follows. 1. The mean score of powerlessness was $52.41{\pm}6.93$, mean mark $3.28{\pm}0.43$, and the mea score of self-efficacy was $45.44{\pm}7.75$, mean mark $2.87{\pm}0.49$, and the mea score of quality of life was $121.27{\pm}23.81$, mean mark $2.96{\pm}0.58$. 2. There were significant differences in the level of powerlessness according to sex(t=2.148, p=.033), occupation(t=3.682, p=.000), economic status(F=3.094, p=.048), experience of hospitalization (t=-2.002, p=.047). 3. There were significant differences in the level of self-efficacy according to age(F=3.271, p=.013), economic status (F=5.759, p=.004), religion(F=2.667, p=.048), hemodialysis period(F=2.991, p=.032), hemodialysis frequency(t=9.045, p=.003), experience of hospitalization (t=4.40, p=.037). 4. There were significant differences in the level of quality of life according to occupation(t=3.796, p=.053), economic status(F=11.478, p=.000), hemodialysis frequency(t=7.573, p=.006). 5.

The objective of this study was to analyze time-dependent changes in bite marks on pig skin. Bite marks produced by the average bite force of adults were analyzed three-dimensionally for 3 hours directly after its formation, at 1-hour intervals. The measured values were calculated by root mean square (RMS) and statistically analyzed by one-way ANOVA test (α = 0.05). The average bite sizes were 0.899 mm, 0.717 mm and 0.506 mm at the first, second and third intervals, respectively, and were significantly different between the three intervals (P < 0.05). A bite mark showed time-dependent changes in the compression level, showing the greatest change in the first interval. Changes in bite marks decreased over time, and bite marks were observed most prominently generated by the anterior dentition.

This paper proposes statistics adaptive linear regression-based object size prediction method for object detection. YOLOv2 and YOLOv3, which are typical deep learning-based object detection algorithms, designed the last layer of a network using statistics adaptive exponential regression model to predict the size of objects. However, an exponential regression model can propagate a high derivative of a loss function into all parameters in a network because of the property of an exponential function. We propose statistics adaptive linear regression layer to ease the gradient exploding problem of the exponential regression model. The proposed statistics adaptive linear regression model is used in the last layer of the network to predict the size of objects with statistics estimated from training dataset. We newly designed the network based on the YOLOv3tiny and it shows the higher performance compared to YOLOv3 tiny on the UFPR-ALPR dataset.
