개인의 identity가 더욱더 중요시되는 현시대에서 ID 도용이나 분실로 인한 피해를 막거나 줄이기 위한 최적의 해법으로 생체 인식이 연구되고 있다. 얼굴인식에 의한 생체인식은 특정 시스템의 입력부위에 신체 일부에 대한 접촉을 강요하지 않으므로 최근 많이 각광받고 있는 분야이다. 그러나 입력된 얼굴 영상은 카메라의 포착 거리에 따라 크기가 달라질 수 있고 또한 얼굴의 기울기 등에 의해 같은 영상이라 할지라도 다른 특징 값을 줄 수밖에 없는 문제점을 안고 있다. 본 논문에서는 주어진 입력영상에 대한 이동, 축소, 확대, 그리고 회전의 단순한 기하학적인 처리를 함으로써 정면 얼굴 영상에 대해 정해진 임계값을 초과 하지 않는 범위에서 일정한 특징 값을 얻을 수 있었다. 본 논문에서 구축된 시스템으로 40 세트의 400 영상에 대한 인식 율을 테스트한 결과 92 %의 높은 인식 율을 보였다.

In general. social cognition for a disabled person seemed that he was limited aspects of emotion and psychology. Thus he was rejected. avoided. worthless and not accepted. People who have been raised in an ethnic collectivity often acquire from that experience not only basic conceps and attitudes toward health and illness but also fundamental styles of interpersonal behavior and concerns about the world. The effects of this enculuration carryover into health- care situation and also become an important influence on personal activities devoted to health maintenance and disease prevention. Our Korean culture is a state of tradition Confucianism. respects his honor and external feature. Therefore recognition of a disabled person is more specipic. This study uses Walker and Avant's process of concept analysis. The concep of recognition of disabilty can be defined as follows : Recognition of disability is a person's conscious process of sensation. perception. memory and thought and is constructed from value. attitude. emotion and expierince which is dynamics. and in everyday life is feeling that basic activity is not free and occurs interaction of envionment. Attributes of disability recognition are defined as 1) It is feeling that basic activity of his daily life is not free in everyday life. 2) It is a person's conscious process of sensation. perception. memory and thought. 3) It occurs interaction of enviornment. 4) It is constructed from value. attitude. emotion and experience. 5) it is dynamics ( changing but not stasis). Nurse is always suppoted and pushed him. She plans institutional and situational surroundings.

Temporal Sign Language Recognition (TSLR) from hand motion is an active area of gesture recognition research in facilitating efficient communication with deaf people. TSLR systems consist of two stages: a motion sensing step which extracts useful features from signers' motion and a classification process which classifies these features as a performed sign. This work focuses on two of the research problems, namely unknown time varying signal of sign languages in feature extraction stage and computing complexity and time consumption in classification stage due to a very large sign sequences database. In this paper, we propose a combination of Dynamic Time Warping (DTW) and application of the Single hidden Layer Feedforward Neural networks (SLFNs) trained by Extreme Learning Machine (ELM) to cope the limitations. DTW has several advantages over other approaches in that it can align the length of the time series data to a same prior size, while ELM is a useful technique for classifying these warped features. Our experiment demonstrates the efficiency of the proposed method with the recognition accuracy up to 98.67%. The proposed approach can be generalized to more detailed measurements so as to recognize hand gestures, body motion and facial expression.

Automatic gain control(AGC) is used in hearing aids to compensate for the hearing level as to reduced dynamic range. AGC is consisted of the main 4 factors which are compression threshold, compression ratio, attack time, and release time. This study especially focus on each individual need for optimum release time parameters that can be changed within 7 certain range such as 12, 64, 128, 512, 2094, and 4096ms. To estimate the effect of various release time in AGC, twelve normal hearing and twelve hearing impaired listeners are participated. The stimuli are used by one syllable and sentence which have the same acoustic energy respectively. Then, each of score of the word recognition score is checked in quiet and noise conditions. As a result, it is verified that most people have the different best recognition score on specific release time. Also, if hearing aids is set by the optimum release time in each person, it is helpful in speech recognition and discrimination.

Today is the era of artificial intelligence. With the development of artificial intelligence, machines have begun to impersonate various human characteristics today. Chatbot is one instance of this interactive artificial intelligence. Chatbot is a computer program that enables to conduct natural conversations with people. As mentioned above, Chatbot conducted conversations in text, but Chatbot, in this study evolves to perform commands based on speech-recognition. In order for Chatbot to perfectly emulate a human dialogue, it is necessary to analyze the sentence correctly and extract appropriate response. To accomplish this, the sentence is classified into three types: objects, actions, and preferences. This study shows how objects is analyzed and processed, and also demonstrates the possibility of evolving from an elementary model to an advanced intelligent system. By this study, it will be evaluated that speech-recognition based Chatbot have improved order-processing time efficiency compared to text based Chatbot. Once this study is done, speech-recognition based Chatbot have the potential to automate customer service and reduce human effort.

This research is related to house entrance recognition of residents, who have long kept the entrance without a closing door in Eoeun village, Geumho, Keongbook. The purpose of the research was to interpret the recognition of a house entrance in Eoeun village with the theories of cultural ecology. Final results suggest the belief for all the inhabitant\`s welfare through anthropological adaptation to habitat. The fish in the Geumho River had sought the shelter from the heavy rain in summer. The Eoeun forest at the entrance of the village provided good shelter for the fish. The Eoeun residents thought that the safe shelter fur the river fish is also semantic for the people. They believed that if the fish could not find shelter, i.e., the Eoeun forest and left, the village could be not safe for their life. Therefore, even the entrance of house should be structurely opened for the fish shelter in a symbolic sense. The entrance without a closing door has implied that their life should depend upon their natural environments because they have believed that till now there have been no considerable accidents in the village.

사람의 감정은 다양한 요소에 의해서 드러난다. 말, 행동, 표정, 옷차림 등등. 하지만 사람은 자신의 감정을 숨길 줄 안다. 따라서 어느 한 가지만으로는 쉽게 그 감성을 짐작할 수 없다. 우리는 이러한 문제를 해결하고 보다 진솔한 사람의 감성을 파악하기 위해 행동과 표정에 주의를 기울이기로 하였다. 행동과 표정은 부단한 노력과 훈련이 없으면 쉽게 감출 수 없기 때문이다. 본 논문에서는 딥러닝 방법을 통해 적은 데이터를 가지고 점진적으로 사람의 행동과 표정을 학습하여 두 가지 결과의 조합을 통해 사람의 감성을 추측하는 알고리즘을 제안한다. 이 알고리즘을 통해 우리는 보다 종합적으로 사람의 감성을 파악할 수 있다.

This study was conducted to investigate the recognition and uses of Astragalus membranaceus. The survey methodology employed was a questionnaire, which interviewed 272(37.8%) males and 448(62.2%) females from the Seoul and Kyunggido area. The main results are as follows: 40-50 years old like and eat Astragalus membranaceus more frequently than 10-30 years old. The most popular reason provided for the preference of Astragalus membranaceus was good health benefits. People indicating a dislike for Astragalus membranaceus had generally fewer previous experiences of eating this plant. The main purchasing place appears to be traditional markets and supermarkets. Astragalus membranaceus was acknowledged as having the following characteristics ‘excellent nutrition’(3.82), ‘natural food’(3.76), ‘possessing anti-cancer and anti-oxidization characteristics’(3.70) and ‘good for liver function, a depressant and good coelenteron effects’(3.62). However, it was not associated with a ‘cheap price’(3.02) and was regarded as ‘difficult for buy’(3.10). Recognition and eating experience was low for Astragalus membranaceus kimchi and rice bread, bread, sauce and Astragalus membranaceus added health drinks. However opinion of its taste was regarded highly.

The purpose of this study is to examine the effects of agriculture on the career adaptation and career decision by measuring the job value and the subjective norm of agriculture. Conclusions based on the study results can be suggested as follows. First, career decision self-efficacy and subjective norm were significant variables in career adaptability of agriculture major college students. Therefore, the belief that one can plan and practice career goals and the affirmation of career plans and decisions in the vicinity are important factors in career adaptability. Second, Self-Realization and social recognition were significant variables in career decision self-efficacy of college students majoring in agriculture. In other words, it can be judged that social recognition such as honor and honor of others in a career choice has a positive effect on the career decision self-efficacy which is self-esteem in career selection. Lastly, An important variable for the subjective norms of agricultural college students was social recognition. This can be said that the positive perception of the surrounding people is very important as the value of social recognition is more important.

Purpose: This study aimed to investigate recognition, attitudes, knowledge, education experience, and education demand regarding physical restraint among laypersons. Methods: A self-reported questionnaire was completed by 105 randomly recruited laypersons in D city. Excluding 2 incomplete answers, 103 data were analyzed by frequency analysis, t-test, ANOVA, and chi-square test using SPSS 23.0. Results: Laypersons' recognition of physical restraints was rated at 3.37 out of 5 points, and showed a positive perspective. Knowledge on physical restraints was rated at 13.68 out of 18 points and was affected by age and education level (F = 2.845, p = .028)(F = 3.126, p = .029) A majority of the participants had no education on physical restraints. Nevertheless, participants showed intention to receive education in physical restraint to reach further understanding. Conclusion: Education on physical restraints is necessary for lay persons. However, there were education limits for people living in modern times. As an intervention addressing this problem, observing videos on the internet is recommended. Moreover, for advertising/educational purposes, accessing the internet and using smart-phone applications are suggested.
