Electrocardiogram (ECG) signals cannot be counterfeited and can easily acquire signals from both wrists. In this paper, we propose a method of generating a coupling image using direction information of ECG signals as well as its usage in a personal recognition method. The proposed coupling image is generated by using forward ECG signal and rotated inverse ECG signal based on R-peak, and the generated coupling image shows a unique pattern and brightness. In addition, R-peak data is increased through the ECG signal calculation of the same beat, and it is thus possible to improve the recognition performance of the individual. The generated coupling image extracts characteristics of pattern and brightness by using the proposed convolutional neural network and reduces data size by using multiple pooling layers to improve network speed. The experiment uses public ECG data of 47 people and conducts comparative experiments using five networks with top 5 performance data among the public and the proposed networks. Experimental results show that the recognition performance of the proposed network is the highest with 99.28%, confirming potential of the personal recognition.
With the development of artificial intelligence, society is moving to a different world. As a result, amid growing interest in artificial intelligence education, research on how to teach artificial intelligence is also being conducted more actively in Korea. However, a lot of research is being conducted around the upper grades of elementary school, and curriculum and programs for the lower grades are insufficient. Therefore, this study developed an artificial intelligence program for lower grades. Among them, it was developed focusing on artificial intelligence image recognition. It compares image recognition methods of people, animals, and computers, identifies the characteristics of fallen leaves, and helps them understand the image recognition process of artificial intelligence by classifying them according to the characteristics of fallen leaves. I hope this program will help elementary school students understand the image recognition principle of artificial intelligence in the future.
Korea is increasingly vulnerable to disasters due to changes in economic and social structure. In particular, there are a number of disadvantaged people, such as elderly people, disabled people, basic livelihood recipients, foreigners, multicultural families, etc. who are vulnerable to social problems due to aging, polarization and internationalization. These vulnerable people to disaster have difficulties in acquiring disaster information and to respond promptly by self-help. Of course, recent studies on vulnerable people to disaster have been steadily increasing, but discussions about foreigners have been relatively inadequate. This has led to a lack of understanding about the actual situation of disaster and coping methods. Once general situations set in, foreigners staying in Korea will suffer from a vicious cycle of policy-making from the viewpoint of Korean and difficulties in obtaining relevant information. In this study, we conducted in-depth interviews on the recognition and acquisition path of disaster information for foreign workers living in Korea. Based on the results of the interviews, we derived implications for practical information, such as ways to understand and actively utilize information media frequently visited by foreign workers in Korea.
This study aims at examining the actual condition of recognition of dental caries(ACRDC), presenting a scheme to improve the recognition, and providing basic data necessary to prevent oral diseases, Dental caries (DC) which one of the three most important chronic diseases in Korea. A survey was conducted on ACRDC for about 390 people twenty and over who visited dental clinics for dental treatment 336 questionnaires with exception of omitted answer were used for statistical analysis. Many of them had never heard of DC and most of them failed to recognize it. People who experienced DC had a dental clinic as a main information channel and they were significant differences in those obtaining information through other channels(p=0.008). Univariate logistic regression analysis for effects on ACRDC demonstrated that possibility of subjects in their twenties recognizing DC more accurately than those in their forties Odds ratio(95% confidence Interval) was 2.06(1.16-3.66)(p=0.000), with the possibility of professionals recognizing the disease more accurately than those with other kinds of occupation 5.49(2.52-11.93)(p=0.000), showing statistically significant relevance. As for medical security, possibility of work insurance being related to more accurate recognition of dental caries than others was 1.95 (1.03-3.71)(p=0.003), with the possibility of subjects whose dental state was very good recognizing dental caries more accurately than those whose dental state was very bad 6.40(1.57-26.03) (p=0.002), showing statistically significant relevance. For prevention of DC, an education through experts working at a dental clinic are necessary for those in their twenties and over, who were other than professionals, who were insured for medical security via other than work insurance, and whose dental state was bad.
In this paper, we develop an Intelligent Wheelchair(IW) control system for the people with various disabilities. The aim of the proposed system is to increase the mobility of severely handicapped people by providing an adaptable and effective interface for a power wheelchair. To facilitate a wide variety of user abilities, the proposed system involves the use of face-inclination and mouth-shape information, where the direction of an Intelligent Wheelchair(IW) is determined by the inclination of the user's face, while proceeding and stopping are determined by the shape of the user's mouth. To analyze these gestures, our system consists of facial feature detector, facial feature recognizer, and converter. In the stage of facial feature detector, the facial region of the intended user is first obtained using Adaboost, thereafter the mouth region detected based on edge information. The extracted features are sent to the facial feature recognizer, which recognize the face inclination and mouth shape using statistical analysis and K-means clustering, respectively. These recognition results are then delivered to a converter to control the wheelchair. When assessing the effectiveness of the proposed system with 34 users unable to utilize a standard joystick, the results showed that the proposed system provided a friendly and convenient interface.
In this, analyzing the type of subjectivity in which people would have about home visit nursing services originating from public health care centers. I tried to research more effective ways to improve home visit nursing care services. and later. for the development of home visit nursing care. to supply basic data. The method for this study was the Q-method. created by William Stephenson. and was adequate for the study of subjectivity. For this study. through the deep interview. literature inquiry, and the discussion course. 206 Q-statement sentences were abstracted. and based on them, after Q-sample-selection. I then collected the Q-categorized-result from 32 subjects from Mar. 10. 2000 to Mar. 25. 2000. Through the statistic a analysis of PC-Qunal program. the subjectivity species were categorized and analyzed. The study results show that there are 3 sorts of recognition types. and they are analyzed in the following; The first type: the positively receiving type shows that they feel thankful and a trusting feeling about home visit nursing. The second type: the negatively mistrusting type shows that they had doubtful attitudes about the specialty of home visit nursing: they wanted medicine or nutrition remedies rather than health education and concerning the their own health care, they prefered the hospitals or clinics. The third type: the conditional receiving type shows that even though they had a positive receiving attitude about home visit nursing wanting to consult with the home visit nurses about the difficult problem which could not easily be settled, hoping that the home visit nurses could visit them more often, in their actual lives. they strongly indicated their attitudes concerning money as more important than home visits. The subjects in these 3 types commonly had a good feeling about the kindness of the home visit nurses: the first and third types also had a positive recognition about home visit nursing; however. in aspects of the evaluation and receiving attitudes, they showed a big difference. When all the above results are integrated. in the case of the first type the home visit nursing service, which satisfied the demand for health care of the medically weak people. should be continuously supplied. Additionally in case of the second type (negatively mistrust). continuous education and support should be supplied with enough interest to lead their concerns about their own health care as well as lead medical spending in a productive and effective direction in order to change their impressions. Through this study. I learned that the recognition of the objectives of home visit nursing services can be categorized in to 3 types and could be analyzed. Thus I wish that this study helps to present basic data which contributes to the development of the home visit nursing field.
Purpose : Amont the various issues concerning bio-ethics, the concern on euthanasia has increased along with the development of medical technology. Thus, the general public tends to have more liberal opinion. They have detail research data and real practices in US, Europe and Australia, but we lack such studies in our country. This study was undertaken to address the need of studies on the recognition of euthanasia among the public because the existing studies have been focused on the medical staff. Methods : Survey 413 people the age of 17 or more, from May to July 2000. Testify the data on the variation of demography and the recognition of euthanasia by using SAS 6.12, the statistic program. Results : 304 people (73.6%) think that euthanasia should be legislated, 156 people (37.8%) permit euthanasia to the rage of voluntary one, and 234 people (56.6%) permit passive euthanasia. When the subject of voluntary euthanasia was himself, more people whose age is 35 or more (P=0.001) responded that they will undertake euthanasia. And, on issues related to the passive euthanasia, one's educational background (P=0.046) and economic power (P=0.040) arrangement showed significant differences. When the subject of voluntary euthanasia is other people, more people whose age is 35 or more than 35 (P=0.001), whose sex is male (P=0.001), and married people (P=0.002) were for allowing the matter. For the subject of passive euthanasia, survey participant's occupation (P=0.016) created meaningful difference. More people whose age is 35 or more than 35 responded that they want voluntary euthanasia for themselves (P=0.001), and in the case when euthanasia is legislated, marital status (P=0.002) also shows meaningful difference. Passive euthanasia is permitted by the more people whose age is less than 35 for respondents other people (P=0.001), marital status show meaningful difference in case for respondent himself. In the case of legal euthanasia is more people whose age is 35 or more than 35 (P=0.001), sex is male (P=0.004) and more married people (P=0.001) responded that they want voluntary euthanasia for other people. And, age (P=0.002), sex (P=0.001), education (P=0.025) and economic power (P=0.001) show meaningful difference for case the subject of passive euthanasia. Conclusion : Most of general public responded that the legislation on euthanasia is required; and, age, education and economic power seem to have an influence on their decisions on euthanasia. Not only such a study of demographic and sociological correlation; but, various basic data on the legislation of euthanasia are needed.

Background & Objectives: This study investigates the recognition on the necessity of the use of radiation for both college students who are considered that they have a high knowledge level in radiation and proposes basic materials to change the recognition of the use of radiation. Also, the investigation was applied to average people who showed the most negative attitudes on radiation. Methods: A questionnaire was applied to 600 college students for five days from October 10 to 15, 2005 and used in statistical analysis. Results: The average value obtained in the recognition of the use of radiation was 76.60 points in which male respondents who were majored in natural science, health, and engineering department and respondents who have experienced radiation related education, radiation diagnosis, and radiation treatment demonstrated higher levels. Also, the average value obtained in the recognition of the radiation damage was 71.66 points in which respondents who were majored in natural sciences, humanities, engineering, and health department showed higher levels than that of respondents who were majored in art and physical department. Groups that exhibited higher recognition levels in the necessity of the use of radiation were male respondents and respondents who were majored in natural science, humanities, and health department and have experienced radiation diagnosis and radiation treatment. In the results of the correlation analysis on the necessity of the use of radiation and recognition of radiation damages, the recognition of radiation damages was presented as negative attitudes in the case of the higher recognition level in the necessity of the use of radiation. Conclusions: Regarding the frequency of the use of radiation in Korea, a 80.9% of university students who showed a high education level had no experiences in radiation related education. Although they showed a relatively high level of 76.6 points in the recognition level of the necessity of the use of radiation, the negative attitude on the radiation damage was also presented as a high level of 71.7 points. Because the providing chance of radiation related information was limited as compared to the atomic power used in Korea and dependancy of the use of radiation, it is necessary to provide the basic information related in the use of radiation to the public. In addition, various investigations on the use of radiation and such negative attitudes are required in future for the public. Also, the correct information of the radiation safety should be delivered to the public.
This research was designed to compare the health condition and the quality of life of the elderly inpatients with those of the normal elderly people. The subjects of study were 482 elderly inpatients and 304 normal elderly people. The research was conducted in July and August using the instrument WHOQOL. The results of the research are as follows: For the level of health, it was recognized that male was healthier than female, having higher the education, living in the city rather than in the rural, keeping the normal life than being in the hospital. There were little difference in the past medical histories of the elderly inpatients and the normal elderly people. As to the diseases currently under the treatment, there were some difference between the elderly inpatients and the normal elderly people but the tendency was similar in the kinds and the frequencies. As to the recognition for the quality of life between the elderly inpatients and the normal elderly people based on the records reflected on each of the domains of WHOQOL, the normal elderly people more positively recognized in the overall quality of life and the following domains: physical, psychological, level of independence, and spirituality/religion/personal beliefs. The normal elderly people more positively recognized especially in the level of independence domain (mobility, activities of daily living, dependence on medication or treatments, working capacity). In the social relationships domain only the sexual activity was significant and the normal elderly people more positively recognized. The elderly inpatients showed the correlation of over 0.5 in the overall quality of life and the following domains: environment, social relationships, physical, psychological, level of independence. It was over 0.6 in the physical domain and the domains of psychological and level of independence. and the psychological domains of level of independence and social relationships. For the points of overall quality of life, it had no correlation with hospitalization but the health condition, residential district, occupation, and taste exerted a significant effect. As a result of separate analyses of the elderly inpatients and the normal elderly people, the health condition and the age only were the common variable which would exercise a significant effect. Besides, the primary factors which would exercise the quality of life were the occupation and taste for the elderly inpatients, and the residential district and source of income for the normal elderly people. In conclusion, it is first and foremost important to improve the standard of health for the overall quality of life for the elderly people, regardless of hospitalization. Therefore, a plan must be urgently drawn up for revitalization of the health promoting projects for the elderly people and the public health projects for the elderly people, and the investment must be increased for settlement of health problems of the elderly people.

Foot-and-mouth disease occurs in cattle or wild animal with two hooves such as cow, pig, sheep, goat, and deer. In this study, survey on knowledge, awareness, and lifestyle about foot-and-mouth disease was performed on 398 elementary school in 5 regions in Gyeonggi-do. 49 people (92.5%) from the group who have been educated about the foot-and-mouth disease replied that they have heard of foot-and-mouth disease and 139 people (68.5%) from the group who have not been educated about the disease replied that they have not heard of the disease. About the knowledge regarding "Foot-and-mouth disease virus is destroyed at temperatures above $50^{\circ}C$, so cooked food is free from the virus", only 26 people (49.1%) from the educated group and 82 people (40.4%) have correct knowledge. When asked about when education on disease such as foot-and-mouth disease, both groups replied that the education should be done in elementary school. The FMD includes in Korea and is a disease where the infection occurrence is happening continuously from the various nation. Must prepare with a recognition and the knowledge where the people are proper.
