In Korea, the collapse of traditional Patriarchal family system has caused the weakening the patriarchal authority which represents the decrease of traditional attitude of respect for old age, influenced by the strong tendency of Materialism in ethics. The urgent problem is how to solve the conflicts of the alienation almost every old people has felt from the society and family which they belong to and how to harmonize the respect for old age who used to have had in the past. From 21st to 30th of July 1979, I explored the small village in Cheju Island with eight students which I selected on purpose that village had preserved the traditionalism. I collected the interview data form a sample of 221 persons of the village in Cheju Island. I studied this small village in Cheju Island for the intention of suggesting the ideal model of regional society which both traditional and non-formal, although the phenomena of nuclear family system and materialism and industrialism are overwhelming in ur present society. Generally people in Cheju Island are economically poor and major occupation is farming, since the industrialization proceeds very slowly and there still strongly remains the traditionalism. Alienation and dissatisfaction of old people from their family and society in Cheju island are less common in comparison to the main land. Old people in Cheju Island usually value the importance of labour. Divison of labour has been well observed in farming, and men and women in Cheju island are equally regarded in comparison to the main land. Old people are independent economically and spiritually from their offsprings and they organize the nuclear family system firmly. Also the old generation is ready to compromise with the new generation and they defy the authoritariansim.

Many taxis called "Mobum" in Seoul are empty and waiting along the curb during the day time. However, it is almost impossible for elderly and handicapped people, and women carrying babies to use them .It is because they can not serve passengers who request services by phone. If taxis, expecially "Mobum" taxis which offer high quality services, can be dispatched based on requests by phone, not only elderly and handicapped people but also auto commuters will easily call and use them. This paper shows a taxi dispatching system. The system minimizes the total empty vehicle hours under given number of empty vehicles and passengers and their locations. As a result, the system maximizes number of services and revenue under given number of taxis. The system adopts a well -known linear programming model and the model can fast and easily be solved by PC level linear programming packages. Also, practical solutions of the system's constraints such as size and travel time forecast are discussed.ecast are discussed.

In the low velocity displacement air-conditioning system, the conditioned air is supplied from the diffuser placed on the wall near the floor and vented near the ceiling. This system has some advantages upon the traditional mixing system; the air quality near the people is improved by the displacing action of the system and the energy may be saved by neglecting the cooling or heating load for the upper space of the space above the people. This study is to examine the temperature and velocity distributions in the room and near the diffuser. It is found that the temperature is stratified uniformly all over the room space to show the displacing function of the system.

In our daily lives, we engage in a variety of tasks that rely on our senses, such as seeing. Blindness is the absence of the sense of vision. According to the World Health Organization, 2.2 billion people worldwide suffer from various forms of vision impairment. Unfortunately, blind people face a variety of indoor and outdoor challenges on a daily basis, limiting their mobility and preventing them from engaging in other activities. Blind people are very vulnerable to a variety of hazards, including falls. Various barriers, such as stairs, can cause a fall. The Internet of Things (IoT) is used to track falls and send a warning message to the blind caretakers. One of the gaps in the previous works is that they were unable to differentiate between falls true and false. Treating false falls as true falls results in many false alarms being sent to the blind caretakers and thus, they may reject the IoT system. As a means of bridging this chasm, this paper proposes an intelligent shoe that is able to precisely distinguish between false and true falls based on three sensors, namely, the load scale sensor, the light sensor, and the Flex sensor. The proposed IoT system is tested in an indoor environment for various scenarios of falls using four models of machine learning. The results from our system showed an accuracy of 0.96%. Compared to the state-of-the-art, our system is simpler and more accurate since it avoids sending false alarms to the blind caretakers.

As the social development progress, social welfare policy for people with disabilities also advance to meet rights of people with disabilities. The personal assistance service(PAS) is the primary service system for persons with disabilities based on guaranteeing the self-determination. The purpose of this study was to compare the personal assistance service system between Japan and Korea to propose improvement plan for Korean system. The comparison of two countries was based on current situation analysis of PAS. The analysis on eligibility criteria, information referral, amount and type of services and service provider, appealing process and service fee deductible etc. The result showed that PAS in Korea is served according to administration convenience than personal need based. Korean PAS policies are limited to particular service amount and type of needed services to satisfy personal PAS need. Whereas, Japan PAS system is served on the philosophy of independent living paradigm and therefore, PAS is provided on personal service needs. The service emphasis is on self-determination and rights on service selection for persons with disabilities. The recommendation for improvement of PAS in Korea are as followed. First, PAS should served under independent living paradigm. Paradigm based service is important because it effects the main theme of PAS; the self determination and rights of service selection. Second, reconstruction of PAS system is needed. As it showed on analysis, eligibility criteria, information referral, amount and type of services and service provider, appealing process and service fee deductible need to be supplemented. Last, to better serve PAS, case management method should be apply. Case management would contribute to settlement of PAS system in Korea. Thru case management, participation opportunities of people with disabilities must be provided during the selection of service quantity and type of PAS.

It takes a lot of time or is even impossible to communicate for people with physical disability and/or speech impairment. Augmentative and Alternative Communication System is an important computerized tool that makes it possible for those people to communicate. Since not only speech impaired people, but also people with other physical disability cannot use conventional computer input devices easily such as keyboard and mouse, so more simple input devices are need for them to communicate. Thus, in this paper, I designed and implemented a communication aid system, with which they can communicate with simple inputs. I collected frequently used sentences by people with disability and categorized them into 9 everyday language groups. With these categories, they can select any sentence with few simple selections. If none of these categories includes the sentences they want, ChunJiIn keyboard is provided so that they can input the sentences, which can be added to the existing language groups for later use. The priority levels of the sentences in each group is constantly readjusted based on usage frequency so that the number of inputs can be reduced.

Both traffic congestion and air pollution in the metropolitan area can be greatly relieved by promoting the use of public transportation with zero emission system. Bus and subway are very convenient means for the people moving in the route areas. But they are not enough to satisfy handicapped or old people to have access to them and also do not solve environmental problems completely. New vehicle system, fuel cell track rapid transit, will be introduced as a countermeasure for such problems in the present paper.

According as society looks graying trend gradually, more shaped system that can achieve measuring health-state of old people more harmoniously construction required in field of old people's welfare and medical treatment. Health-state is measured by two methods of contact and non-contact. The first, for example measurement of blood pressure or electrocardiogram, requires that measuring equipments are attached on human body but the second, for example X-Ray or MRI, is not. But both of methods are have some of defect, for example attaching equipments, needing of the special equipments or the necessary time, etc. Therefore desirable method of monitoring system must have minimum interrupt about daily life. This study suggest the system that can monitor the user, especially old people's outward aging and health-state by use the PAN TILTER and CCD camera.

In a previous work we have done, we presented a monitoring system to automatically detect some dogs' behaviors from videos. However, the input video data used by that system was pre-trimmed to ensure it contained a dog only. In a real-life situation, the monitoring system would continuously receive video data, including frames that are empty and ones that contain people. In this paper, we propose a YOLOv4-based system for automatic object detection and trimming of dog videos. Sequences of frames trimmed from the video data received from the camera are analyzed to detect dogs and people frame by frame using a YOLOv4 model, and then records of the occurrences of dogs and people are generated. The records of each sequence are then analyzed through a rule-based decision tree to classify the sequence, forward it if it contains a dog only or ignore it otherwise. The results of the experiments on long untrimmed videos show that our proposed method manages an excellent detection performance reaching 0.97 in average of precision, recall and f-1 score at a detection rate of approximately 30 fps, guaranteeing with that real-time processing.

An ontology provides an explicit specification of concepts and relations on information extracted from database or on human knowledge. Using an ontology, The information can be reconstructed according to semantic relations. In this paper. IT-People Event Ontology is constructed using people information extracted from web portals. IT-People Event Ontology represents constant information and time-temporal information on people. A system using this ontology outputs the well-organized reconstructed information on a specific individual in interest, and then the reconstructed information is suitable for users' demand.
