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.

본 논문은 객체 검출 알고리즘을 위한 통계치 적응적인 선형 회귀 기반 객체 크기 예측 방법을 제안한다. 기존에 제안된 딥 러닝 기반 객체 검출 알고리즘 중 YOLOv2 및 YOLOv3은 객체의 크기를 예측하기 위하여 네트워크의 마지막 계층에 통계치 적응적인 지수 회귀 모델을 사용한다. 하지만, 지수 회귀 모델은 역전파 과정에서 지수 함수의 특성상 매우 큰 미분값을 네트워크의 파라미터로 전파시킬 수 있는 문제점이 있다. 따라서 본 논문에서는 미분 값의 발산 문제를 해결하기 위하여 객체 크기 예측을 위한 통계치 적응적인 선형 회귀 모델을 제안한다. 제안하는 통계치 적응적인 선형 회귀 모델은 딥러닝 네트워크의 마지막 계층에 사용되며, 학습 데이터셋에 존재하는 객체들의 크기에 대한 통계치를 이용하여 객체의 크기를 예측한다. 제안하는 방법의 성능 평가를 위하여 YOLOv3 tiny를 기반으로 제안하는 방법을 적용하여 재설계한 네트워크의 검출 성능과 YOLOv3 tiny의 검출 성능을 비교하였으며, 성능 비교를 위한 데이터셋으로는 UFPR-ALPR 데이터셋을 사용하였다. 실험을 통해 제안하는 방법의 우수성을 검증하였다.
