Purpose: This study was to identify health needs of the elderly at nursing homes by long-term care grade. Methods: The health needs of 116 elders at two nursing homes in Seoul were measured with resident assessment protocols (RAPs), activities of daily living (ADL), and cognitive performance scale (CPS), and pain and depression were measured by resident assessment instrument (RAI). Results: With regard to RAPs, 11 out of 18 items had different distribution in the 3 groups significantly. The 1st-grade elders had a higher percentage of 9 items than the 2nd- and 3rd-grade ones but the 3rd-grade ones had the highest health needs related with activity. The 2nd-grade elders had similar health needs to the 1st-grade ones. In terms of functional level, the 1st-grade elders had the highest percentage of CPS and ADL but the 3rd-grade ones had the highest score of pain and depression out of the 3 groups. The standardized assessment instrument to identify specific health needs by the 3 groups should be developed. Therefore, care plans to meet health needs of the 3 groups will be made. Conclusion: It is suggested that nursing care is required to the elderly of the 1st- and 2nd-grade and safe activity and environment to the 3rd-graded ones.

본 연구는 식물원 방문객의 효과적인 관리를 위해 그들의 생태의식과 욕구구조의 연관성 규명을 목적으로 시작하였다. 이를 위해 '식물원 이용자의 생태의식과 이용동기수준의 파악', '이용자의 인구통계학적 특성이 생태의식에 미치는 효과', '생태의식과 이용동기와의 연관성 규명'을 연구문제로 설정하였다. 실증분석은 경기도 일원 3개 식물원 방문객 대상의 설문조사로 진행하였다. 이용객의 생태의식은 던랩(Dunlap)의 15개 NEP 척도로 측정하였고, 이용동기는 매슬로우(Maslow)의 7단계 욕구를 활용했다. 3개 조사대상지에서 3일간 조사한 끝에 각 360부의 설문지를 확보하여 본 분석에 사용하였다. 연구 결과, 이용객들의 생태의식과 이용동기는 보통 이상의 높은 수준이었다. 생태의식에서는 '자연균형과 생태위기'와 '반인간 중심주의'에 대한 반응이 높았다. 이용동기에서는 '인지적 욕구'가 가장 높았고, 그 다음은 '애정 및 소속의 욕구', '생리적 욕구'의 순이었다. '자아실현 욕구'와 '자존의 욕구'는 가장 낮았으며, 이 둘을 제외하면 대체로 상위욕구의 비중이 높은 반응을 보였다. 생태의식과 이용동기는 상관성 분석 결과, 부(-)적 상관과 정(+)적 상관이 섞여 있었으나, 정적 상관의 비율이 70% 이상으로 높았다. 분석결과 생태의식과 이용동기는 대체로 낮은 수준의 정적 상관관계 중심으로 형성되어 있다고 볼 수 있다. 특히 '생리적 욕구'와 '인지적 욕구'가 생태의식과 상관성이 높았는데 이는 이 두 욕구가 각각 식물원 방문객의 하위욕구와 상위욕구를 대표하는 욕구로 판단된다. 즉, 식물원 방문객이 학습목적성이 강하지만, 이와 동시에 신체적인 휴식공간으로서의 기대감 또한 적지 않음을 알 수 있다. 연구 결과, 식물원 방문객의 생태의식은 보통 이상의 높은 수준인데, 향후 지속적인 증가가 예상되었다. 따라서 이용동기 또한 계속 높아질 것이며, 특히 '심미적 욕구'와 '인지적 욕구'가 커질 것으로 예상된다. 따라서, 식물원의 시각적 자원을 활용한 경관관리가 중요함을 알 수 있다. 아울러 방문객의 지적 욕구를 채워줄 수 있는 컨텐츠가 지속적으로 제공되어야 할 것으로 판단된다.

Mental workload has a improtant place in modern work environment such as human-computer interaction. Designing man-machine system requires knowledge and evaluation of the human cognitive process which controls information flow during our works. Many studies estimate reaction time as a index of menatal workload. This paper investigates what reflacts the workload of human information handling when the informations grow its degree. Experiment result introuce the memory time that explain the information-load more sensitive than react time. And react time shows learning effect but memory time does'nt show that effect So it can be concluded that cognitive learning or work schema needs more time to achieve dexterity than motor skill.

The purposes of this study were to describe the level of vision and hearing impairments, depression and functional capacity, among Korean institutionalized elderly and to examine the relation-ship between sensory impairments, depression, and functional capacity in these people. The final pupose was to test the cognitive function path model using sensory competencies as predictors. A convenience sample of thirty nine male and 90 female subjects with a mean age of 80.5 were the subjects of this study. The subjects were tested for cognitive function, and vision and hearing impairments. Physical function and social function were measured by observation of designated task performance by the subjects. Their level of de-pression was measured using a Geriatric Depression Scale administered through an interview. Individual subjective ratings of hearing and vision were marked by the subjects, on a ladder scale. The results of the study showed that 48.8% of the subjects had a hearing impairment, 63.5% had a vision impairement, and 36.4% had both a vision and hearing impairement. The four sensory groups (no sensory impairement, hearing impairement, vision impairement, hearing and vision impairement) were tested for differences in depression, physical function, social behavior and cognitive function. The only significant difference that was found was in cognitive function, between the no sensory impairement group and the hearing and vision impairement group(F=3.25, P<.05), Subjective ratings of hearing showed a significant correlation with cognitive function(r=.34, p<.001) and with social behavior(r=.31, p<.001). There was no correlation between subjective vision ratings and cognitive function or social behavior. However there was a significant correlation between vision and hearing(r=.49, p<.001). There was also a significant negative correlation between age and vision(r=-.21, p<.01) and between age and hear-ing(r=-.34, p<.001). There was a significant correlation between depression and physical function (r=-.32, p<.001) but there was no correlation between depression and cognitive function or social behavior. Based on the literature review and the result, this study, a path model of sensory competence-> cognitive function- >social behavior was developed and tested : Perceived vision and perceived hearing were the exogenous variahles and cognitive function and social behavior were the endogeneous variables in the model. The path analysis result demonstrated an accept-able fit (GFI=.997, AGFI=.972, X$^2$=.72 (p=.396), RMSR=.019) between the data and the model. There was a significant direct effect($\beta$=.38) of perceived hearing on cognitive function. There was a significant direct effect ($\beta$=.32) of cognitive function on social behavior. The total effect of hearing on social behavior was $\beta$=.32 including the indirect effect ($\beta$=.12) . However perceived vsion had little effect ($\beta$=-.08) on cognitive function. The result of path analysis confirms that hearing levels influence cognitive function, and both hearing and cognitive function levels influence social behavior. However, vision has little effect on cognitive function or on social behavior. For the next study, a combined model of the pre viously developed environment - >depression- > physical and social function model, and the present cognitive function model, should be tested to further refine the functional capacity model. There also a need for longitudinal study of functional capacity and sencory competence in order to better understand how declining sensory competence influences functional capacity and how it effects in-creasing dependency and nursing needs in the elderly.

Purpose: The purposes of this study were to develop and test a prediction model for caregiving experiences including caregiving satisfaction and burden in dementia family caregivers. Methods: The stress process model and a two factor model were used as the conceptual frameworks. Secondary data analysis was done with 320 family caregivers who were selected from the Seoul Dementia Management Survey (2014) data set. In the hypothesis model, the exogenous variable was patient symptomatology which included cognitive impairment, behavioral problems, dependency in activity of daily living and in instrumental activity of daily living. Endogenous variables were caregiver's perception of dementia patient's unmet needs, caregiving satisfaction and caregiving burden. Data were analysed using SPSS/WINdows and AMOS program. Results: Caregiving burden was explained by patient symptomatology and caregiving satisfaction indicating significant direct effects and significant indirect effect from unmet needs. The proposed model explained 37.8% of the variance. Caregiving satisfaction was explained by patient symptomatology and unmet needs. Mediating effect of unmet needs was significant in the relationship between patient symptomatology and caregiving satisfaction. Conclusion: Results indicate that interventions focusing on relieving caregiving burden and enhancing caregiver satisfaction should be provided to caregivers with high levels of dementia patients' unmet needs and low level of caregiving satisfaction.

Immigration of Koreans to the United States has increased since the 1960's. Adjusting to life in the United States produces a great deal of stress for immigrants. Despite better economic opportunites, many see the U.S. culture as threatening to their family and cultural values. Differences in culture, language, expectations and social behavior can lead to misunderstandings between health care providers and clients. These misunderstanding can leaf to frustration on the part of each. The ultimate result of this is that often Korean-immigrants do not get their health care needs met and stress response symptoms can lead to disease if there is no appropriate care. To determine the health care needs and concerns of Korean-Americans, a health needs assessment is needed. Appropriate and adequate information about the health care needs of these individuals is important as it relates to American policy changes allowing greater numbers of immigrants to enter the U.S. The purpose of this prospective study was to describe Korean-American stress response. This study focused on the primary presenting problems for which subjects reported having sought care. These included a variety of stress-related symptoms, including peripheral manifestations, cardiopulmonary symptoms, central-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, depression, anxiety, emotional irritability and cognitive disorganization. Of the 300 subjects who entered the study, 80% (N＝223) completed the questionnaire in full. Demographically, the percentage of females and males was 50% each and they ranged in age from 20 to 69 years. Ninety percent of the subjects were highly educated, 25% owners of business, 25% white collar professionals, 15% employed in sales or as skilled /unskilled labor, 30% had no occupation : and 5% were housewives or students. The SOS inventory is designed to quantify self-perception of behavioral, cognitive, and physiological components of the stress response. It consisted of 94 items divided into 10 subscales. The result of this study are as follows : The total mean 505 of all subjects (N＝223 was .8129 ; the mean 505 for male(N＝114) was .7665 and for females, (N＝108) .8594. The level of symptoms for central-neurologic and muscle tension was higher for than for males. The highest stress response of all subjects was emotional irritability symptoms(1.0644) : the lowest stress response of all subjects was peripheral manifestation symptoms.

Purpose: This study was done to identity the degree of instructional motivation and response after application of CAI in the student nurses' fundamental nursing course. Method: The subjects of this study were 77 student nurses and the data was collected from October, 7th to 17th in 1997. The examination sheet for cognitive style and a questionnaire to evaluate the degree of instructional motivation were used to collect data. Result : 1) It was found that the degree of instructional motivation of the learner was higher in the CAI class. (134.23/170) 2) After CAI, the learners expressed relatively higher satisfaction in understanding, interest, degree of difficulty, number of problems, icons, and extra information. 3) It was found that 53 learners(68.8%) were field independent-cognitive learners and 24 learners(31.2%) were field dependent-cognitive learners. 4) Among the instructional responses according to the cognitive behavior of the learner after CAI, there were significant differences in reasons for understanding the computer program, interest in the computer program class, and the number of students assigned to each computer. 5) There were no significant difference between cognitive style and instructional motivation. Conclusion: The CAI effect for nursing students fundamental nursing course have been positive evaluated. CAI in nursing education is becoming very available and needs to develop effective CAI and use not only fundamental nursing course but also another nursing education programs.

To fly a drone or unmanned aerial vechicle(UAV) safely, its pilot needs to maintain high situation awareness of its flight space. One of the important ways to improve the flight space awareness is to integrate both the global and the local navigation map a drone provides. However, the drone pilot often has to use the inconsistent reference frames or perspectives between the two maps. In specific, the global navigation map tends to display space information in the third-person perspective, whereas the local map tends to use the first-person perspective through the drone camera. This inconsistent perspective problem makes the pilot use mental rotation to align the different perspectives. In addition, integrating different dimensionalities (2D vs. 3D) of the two maps may aggravate the pilot's cognitive load of mental rotation. Therefore, this study aims to investigate the relation between perspective difference ($0^{\circ}$, $90^{\circ}$, $180^{\circ}$, $270^{\circ}$) and the map dimensionality matches (3D-3D vs. 3D-2D) to improve the way of integrating the two maps. The results show that the pilot's flight space awareness improves when the perspective differences are smaller and also when the dimensionalities between the two maps are matched.
