This study has been performed to review critical issues affecting continuous residence in profit(self-paid) assistant living facilities for the elderly in the United States. There are three factors influencing continuous residence of frail elderly in the facilities as long as they want without involuntary discharge : Financial ability, behavioral aspects, and facility management situation. Regarding financial ability, income, purchase of insurance policy, cashable assets, willingfulness to pay, and health status were found to be crucial determinants of continuous residence. Overall, 40-50% of those aged 65+ are financially able to stay in the assistant facilities as long as they want, without involuntary discharge. As for behavioral aspects, extroversions, congeniality, culture & life style, conscientiousness, preference for person, and physiological habits were found to be crucial determinants of continuous residence. As for the management situation, it is essential that facilities reach nature level of self-governing rights of the older residents and good local images, and conflicts among the residents and managing parties be resolved on the agreeable standards of inspectors. finally in this study, it is proposed that in Korea, national pension authority offer a liability package for assistant residence, for the case of individual bankruptcy.

최근 인공지능 기술과 로봇 기술의 발전으로 인해 비서 로봇을 만드는 기술적인 가능성이 커지면서 업무 자동화를 위해 많은 기업에서 도입하고 있다. 특히 인구 고령화가 진행되면서 노동력 부족이 심각한 문제로 대두되고 있다. 현재 비서로봇은 정형화된 대화는 잘 처리하지만 비정형화된 대화에 대해서는 한계가 있다. 본 논문은 앞선 문제를 해결하기 위해 비정형화된 대화도 가능하면서 사용자가 원하는 행동을 실행할 수 있는 보편화된 비서 로봇을 선보인다. 음성인식 모듈과 구글 어시스턴트를 활용하여 마이크를 통해 비서 로봇에게 스케줄 관리, 날씨 등을 질문하고, 스피커를 통해 대답을 듣는 등 비정형화된 의사소통을 할 수 있으며, 비서 로봇에게 원하는 행동을 지시하여 행동을 구현시킬 수 있는 비서로봇을 제안한다.

Supersonic, axisymmetric, jets issuing from several kinds of dual, coaxial, nozzles were experimentally investigated. Four different kinds of coaxial, dual nozzles were employed to characterize the major. features of the supersonic, coaxial, dual jets. Two convergent-divergent supersonic nozzles with different impinging angle on the jet axis of were designed to have the Mach number 2.0 and used to compare the coaxial jet flows with those discharging from two sonic nozzles. The primary pressure ratio was changed in the range from 4.0 to 10.0 and the assistant jet ratio from 1.0 to 4.0. The results obtained show that the assistant jets from the annular. nozzle affect the coaxial jet flows and an increase of both the primary jet pressure ratio and assistant jet pressure ratio lead to a longer supersonic length of the dual, coaxial jet.

Dental assistant in South Korea, The work is overlapped considerably between dental hygienist and dental practical nurse. Moreover, dental technician, hospital coordinator work in dentistry consultation deeply. It cause friction among work scope of occupation's type. Accordingly It is purpose to get basic data which is necessary to deduce division of work training and utilization of human resources in oral health distinguish clearly between business occupations. Also compared and analyzed via analysis of frequency and ANOVA above 10 works around something legal work of dental hygienist regarding work reality of dental assistant in dental clinic and hospital. Compare with scaling, representative item about 10 works center on legal work of dental hygienist, is implementing dental technician 9(75%), practical nurse 64(87.67%), etc. 11(64.71%). Dental assistant except dental hygienist is implementing indigenous legal work of dental hygienist. Dental institution secure enough man power, It is suggested necessity for policy means regarding role and work scope of dental assistant.

In this paper, we propose the algorithm that improves the linearity of the walking assistant robot on lateral slopes. The walking assistant robot goes out of the course due to the rotational moment which is caused by the weight of the robot and the slope. To compensate this, we give the weight to each driving axle after comparing the real rotational angular velocity with the target rotational angular velocity which is entered by an user. The results of applying the algorithm to the real walking assistant robot show that the yaw axis deviation of the robot without the algorithm diverges, but the yaw axis deviation of the robot with the algorithm lies within 20cm, which can be recognized as stable. In addition, the changing rate of the course deviation is stabilized and shows no more course deviation, after moving 300cm.

Recent advanced sensors and communication technologies have been widely applied to advanced safety vehicle (ASV) for reducing traffic accident and injury severity. To apply the advanced safety vehicle technologies, it is important to quantify the safety benefits, which is a fundamental for justifying application. This study proposed a methodology for quantifying the effectiveness of the advanced driver assistant system (ADAS), and applied the methodology to lane departure warning system (LDWS) and automatic emergency braking system (AEBS) which are typical advanced driver assistant systems. When the proposed methodology is applied to 2008-2010 gyeonggi-province crash data, LDWS would reduce about 10~14% of relevant crashes such as head-on, run-off-the road, rollover and fixed-object collisions on the road. In addition, AEBS could potentially prevent about 50% of total rear-end crashes. The outcomes of this study support decision making for developing not only vehicular technology but also relevant safety policies.

Purpose: Community child centers (CCCs) were introduced to provide after-school activities and care, including meal services to children from low-income families. The assistant cooks, who have the main responsibility for making and serving food at CCCs, are a major factor influencing the eating habits of children using CCCs. In this study, we tried to identify and understand who the assistant cooks are, what their job responsibilities are, and what they need in order to be able to provide children with healthy meals. Methods: Three focus group interviews were held with 17 workfare program participants who worked as assistant cooks at CCCs, and content analysis methods were applied using the NVivo 12 qualitative data analysis software. Results: The assistant cooks reflected on their perceptions of the children's health at the CCCs, their own cooking style, and their role at the CCCs. Additionally, barriers to the optimal provision of their services were pointed out, and improvements were suggested. Conclusion: The results of this study can be used as a fundamental resource for the development of tailored interventions that consider a child's unique environment to address health disparities, specifically with respect to childhood obesity.

Currently, in spite of continual efforts the information utility of construction industry has low-efficiency for the other industry. These problems arose from the erroneous efforts for the information utility of construction industry. Because it left out of consideration of the construction characters, which are the center of construction sites, and this information system was directly introduced and operated from the other industry. Also, we can point out mistake that the existing information systems disregarded using facility in the fixing of these problems. Therefore, this study describes a new process, which purposes to build and utilize construction information management system as using Personal Digital Assistant (PDA) of the mobile communication concept, to solve the problems of existing construction information management system.

Objectives To identify whether Sovereign-Minister-Assistant-Courier (君臣佐使) Theory and Meridian Tropism (歸經) Theory of oral herbal medicine can be applied to trans-dermal medicine and whether pharmaceutical efficacy can be delivered to skin by Courier herb (使藥). Methods We reviewed previous studies related to Sovereign-Minister-Assistant-Courier Theory. And we examined whether prescription compositions based on Sovereign-Minister-Assistant-Courier Theory correspond with efficacy results of trans-dermal medicine experimentally identified. Results When Sovereign-Minister-Assistant-Courier Theory is applied to trans-dermal medicine, Courier herb act as delivering the effective components to the lesion penetrating skin barrier. And we identified that medicine absorbed through the digestive processes may not correspond with Courier herb applied topically. Conclusions We identified that Courier herb act as delivering the effective components to the lesion. But to strength evidences, additional studies on this action will be needed.
