The purpose of this study was to analyze factors affecting malnutritional status of elders with dementia in facilities. The subjects were 140 elders with dementia residing in three nursing facilities in Chungnam, South Korea. Data were collected from May 30 to September 30 in 2016, using questionnaires. The collected data were tested by t-test, ANOVA, correlation, regression analysis. The malnutritional status of elders with dementia in facilities was high in the high-risk group (84, 60.0%), and the nutritional status was appeared to be related to sex, long-term care grade, Korean version-Activities of Daily Living and feeding difficulty and cognitive function. As a result of multiple regression analysis, significant influence variables on malnutritional status were Activities of Daily Living(${\beta}=0.379$, p=.001), feeding difficulty(${\beta}=0.264$, p=.001), cognitive function(${\beta}=-0.187$, p=.014) and these variables showed an explanatory power of 35.9% on malnutritional status. The results of this study are expected to be used as basic data for the development of malnutritional status improvement program for elders in facilities with dementia.

The study was conducted with the aim of identifying the impact of competition anxiety on dance immersion and performance in high school students majoring in dance. As of 2020, online surveys were conducted on students majoring in dance at high schools in Seoul and the metropolitan area. A total of 222 people's data were processed by applying t-test, one-way variable analysis, correlation and multiple regression analysis through SPS 18.0 for Windows, resulting in the following conclusions. First, male students were more confident in their condition than female students, and students who recognized that their family's economic power was in the middle class were more aware. In addition, it was found that the group perceived that economic power was at the top of the list was higher than the median. Second, cognitive anxiety and self-confidence have been shown to have a static effect on immersion into dance. Third, cognitive anxiety and self-confidence have been shown to have a static effect on the achievement of uselessness. Fourth, immersion in dance appeared to be a powerful parameter related to competition anxiety and achievement of dance. To sum up the above conclusions, competition among high school students majoring in dance has been shown to increase their performance by immersing themselves in dance, but further studies of these psychological variables are expected to have side effects.

This research analyzed how the new and senior security guards employed privately are influenced on their task performance by the factors operated before task performance: cognitive state anxiety, physical state anxiety and state confidence which are the sub-factors of the Competitive State Anxiety(CSAI-II) according to the educational background, career, gender and athletic capacity. First, as for the new and senior security guards' state anxiety before task performance, the senior guards felt the cognitive anxiety more than the new guards, but there was not a distinct difference statistically. Therefore, it is estimated that there is little difference in the level of cognitive anxiety between the new security guards with insufficient career and the seniors. Second, the level of the physical state anxiety was shown higher from the senior guards than from the new ones and had a distinct difference. However, it seems to be derived from the extent of physical development as the seniors are at the time of vigorous physical development. Third, the level of state anxiety had no distinct difference between them statistically though the new security guards felt it higher than the seniors. Fourth, the state confidence was shown higher from the seniors than from the new and had a distinct difference statistically, also. Fifth, as for gender, the male and female guards did not have a difference so much in the cognitive and physical state anxiety, and state confidence. Sixth, as a whole, the state anxiety was highest as for the security guards with athletic capacity level 1 and 2. Those with the level 2, and 3 and the level above 7 felt it less than those with the level 5-6, which had a distinct difference in statistics. The manager of the new and senior security guards should make them dispel anxiety in piece of mind through physical and mental education encouraging them to have self-confidence, practical training, and psychological training based on the analysis of causes of various cases.

Traffic broadcasting is using a usual traffic information announcement when giving its information to users on the road and for the provision of information useful to drivers, a clear criteria of how to judge with information from informers needs to be established from the perspective of users. In this study, to give some available criteria for current announcement which often causes confusion, cognitive characteristics were investigated and analyzed based on judgment criteria which are commonly felt by correspondents, participants in traffic broadcasting and drivers. The result requires the provision of information that is relied on an average speed where drivers feel little cognitive difference and found a classification where a smooth traffic flow is more than 60km/h, going slow 40~60km/h and congested state less than 40km/h respectively. And from the study of 35 traffic information announcement for different traffic situations, 8 cases of smooth state and 9 cases of congested state were clearly classified but the rest 18 cases of comment were ambiguously perceived by drivers and which requires the necessity of a announcement that uses directly the word of 'smooth', 'slow', and 'congestion' in the actual expression of slow driving. The future study should be focused on the establishment of more definite criteria by representation of nearly real traffic flow, provision of traffic information announcement and the analysis of cognitive response through car dynamic simulators and the kinds.

This study was conducted to determine the levels of cognitive impairment (MMSE-K) among centenarians, and to reveal their association with related variables. The study subjects were 268 centenarians who received medical check-ups from the National Health Insurance Corporation during the period of 2016-2017. The levels of cognitive impairment were significantly reduced among females as well as those living with spouses and children, lower monthly income, lower BMI and individuals who engaged in smoking and alcohol consumption without regular exercise relative to their respective counterparts. The risk of definitive cognitive impairment in study subjects was significantly higher among women (ORs=9.85, 95% CI=2.88-33.59) than men and was lower in obese group (ORs=0.25, 95% CI=0.07-0.86) than in low weight groups, as well as in non-smoking (ORs=0.30, 95% CI=0.10-0.83) than smoking groups. The factors influencing the cognitive impairment of study subjects were sex, living status, monthly income, BMI and smoking status. Taken together, these results suggest that the levels of cognitive impairments among centenarians differed significantly in response to socio-demographic characteristics and health related variables. Especially, the levels of cognitive impairments decreased among those with poor health related variables such as smoking, alcohol consumption and regular exercise.

This study examined the characteristics of brain's reaction pattern concerning the preference for product images and compared them with the result of subjects' intuitive evaluation of their preference for the same materials. Two tests were conducted; the first one that calculated comfort properties based on brainwave measurements in order to examine the impression given by the images of products presented separately, one-by-one, and the second one that had subjects evaluate the preference directly by comparing the images of all products simultaneously. The first test was titled 'Independent Cognitive Response' and the second test, 'Relative Cognitive Response', and their characteristics were as follows. In the 'Independent Cognitive Response', the state of emotion was expressed in absolute values based on the comparison with the information accumulated through the subject's own experience and the feeling expressed as 'pleasant' or 'unpleasant' persisted as absolute values. In the 'Relative Cognitive Response', the state of emotion relative to the information of other images compared in the stage of perceiving the images was expressed, and in this case, the state of emotion described as 'calm' or 'excited' acted as relative values.

Research on gait recognition and its use is actively underway. This study suggests a method to recognize abnormal gaits of pedestrians. The purposes of the existing research to recognize normal steps are to measure physical activities and to validate people by their walks, but the purpose to recognize abnormal steps in this study is to insure the safe life of pedestrians. There are situations in which pedestrians are unaware of themselves vulnerable and can not ask for help. The purpose of this research is that even if pedestrians are unaware of themselves and there are no spontaneous requests for helps, it is intended for them to escape from dangers and difficulties by adopting the recent IOT technology. Hence, this study analyzes normal pace of pedestrians using the triaxial acceleration sensors, and takes ranges of their normal walking. And then, the steps of pedestrians are measured using the triaxial acceleration sensors, contrasted with their normal walking ranges, and determine whether their steps are normal or not. When it is out of the state for normal paces, a method to determine as abnormal paces is suggested.

임상추론은 환자를 평가하고 관리하는데 사용되는 임상가의 필수적인 생각 또는 동적인 인지과정이라고 할 수 있다. 임상추론은 환자의 문제를 인식하고 식별하며 더 나은 환자관리가 이루어지도록 환자의 상태에 대처하며 정보를 해석하고 분석하는 것으로서 이를 위해 임상가는 적절한 지식을 가지고 있어야 하며 임상추론 기술과 관련된 폭넓은 이해가 요구된다. 임상추론은 치료사, 환자, 그리고 환경간의 상호관계를 가진 복잡한 과정으로 임상추론과정에서 치료사와 환자간에는 충분한 협조가 이루어져야 한다. 임상추론에서의 해석적 모델로는 진단적 추론, 상호작용의 추론, 이야기적 추론, 협조적 추론, 예언적 추론, 윤리적 추론, 추론의 교육 등이 제시된다. 임상추론 과정에서 필수적인 주요 요소는 충분한 지식, 인지와 초인지 기술을 포함하며 이들 요소는 치료사와 환자간의 관계에서 발달되어야 한다. 이들 기술 중에 어떠한 실수라도 임상추론의 오류를 초래할 수 있다. 추론에서 오류의 원인으로는 암시된 정보의 잘못된 인지, 임상페턴에 대한 지식부족, 특정 상태에 대해 알려진 사실을 잘못 적용하는 경우를 들 수 있다. 오류는 임상추론 과정의 어떤 단계에서도 일어날 수 있으므로 효과적인 학습전략을 통하여 이들 오류를 예방할 수 있을 것이다.
