In this paper, we propose a method of cooperative control (T-cell modeling) and selection of group behavior strategy (B-cell modeling) based on immune system in distributed autonomous robotic system (DARS). Immune system is living body's self-protection and self-maintenance system. These features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For applying immune system to DARS, a robot is regarded as a ？3-cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-cell respectively. When the environmental condition (antigen) changes, a robot selects an appropriate behavior strategy (antibody). And its behavior strategy is stimulated and suppressed by other robot using communication (immune network). Finally much stimulated strateby is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and immune network hypothesis, and it is used for decision making of optimal swarm strategy. Adaptation ability of robot is enhanced by adding T-cell model as a control parameter in dynamic environments.

Twenty-first century coming of health care in our country is in a situation of much conflict because the relationship between nurses and doctors is seen in terms of a traditional and vertical structure. Accordingly. it is very difficult to find collaboration amongst individuals of these two professions. Now nursing is trying to find independence and autonomy by carrying out independent professional skills. This study on collaboration and the obstacles hindering its pursuit. The strategies of collaboration to give better health care quality are as follows; First, a program for professionals should be developed to enhance professional knowledge and technology and train nursing professionals so that nursing can be acknowledged as a profession with a power to carry out on independent job. Second, collaboration reduces expenses and results in satisfactory performances of duty, high productivity, low incidence of medical accident, and higher satisfaction of the patient. Therefore the leader in the higher position should take positive stance for collaboration and help create a cooperative situation through the development of practical orders for collaboration. opening cooperative wards, and meeting for collaboration. Third, a collaboration model should be introduced into the courses of the nursing and medical school curriculum, which would influence job atmosphere after graduation. Fourth, nurses should have pride in their jobs as professionals and have confidence in their professional skill, knowledge and ability. Nurses should make an effort to share responsibility and have independence and autonomy. Fifth, common people as well as doctors know little about professional practice and the role of nurses, so a publicity campaign is also required.

The aim of this study was to determine the factors contributing to the barrier of dental treatment for special needs patients perceived by the main caregivers of the patients. A questionnaire was developed with three parts: patient-related factors, caregiver-related factors, and factors for treatment barriers. Patient- and caregiver-related factors were analyzed for correlations with the barrier factors. Fisher's exact test and Chi-square test were used at the level of 0.05. A total of 52 caregivers (mean age [SD]=50.2 [11.5] years) for the patients with intellectual and cognitive disabilities (mean age [SD]=38.9 [21.3]) responded to the questionnaires. Oral hygiene status, need for assistance in tooth brushing, and cooperation for tooth brushing were correlated with the level of treatment cooperation of the patients (p<0.05). The above three factors were also correlated with the treatment barrier despite patients presenting oral symptoms (p<0.05). Two thirds of the caregivers felt the treatment cost as severe or a considerable financial burden. For patients, insurance types and need for assistance in tooth brushing, and for caregivers, education levels and financial status were significant factors contributing to financial burden (p<0.05). There were background factors of the patients and their caregivers associated with access to dental treatment for special needs patients. Deficient cooperative skills and financial burdens were the main obstacles to treatment access. Tooth brushing skills and oral hygiene status can be proxy measures to cooperative ability for dental treatment.

Background and objective: There are many theories related to the development of agrotourism, and each stakeholder has its own role and function. If it is based on organizational functions, stakeholders need to be coordinated, and the state plays a major administrative role. But in the successful case of Yeongdong County, Chungcheongbuk province, the Republic of Korea, the government played an important role in the development of tourism, which grants us another perspective on the role of the government in promotion and development agrotourism activities. Methods: This article aims to examine the development of agrotourism through a cooperative approach, by clarifying the role of the local authorities in the Yeongdong region in the management and operation of the local agrotourism activities. The qualitative research method is based on a field survey conducted in Yeongdong County in 2019. Results: The study's findings show that in situations where conflicts of interest among stakeholders are prone to occur, the development of local tourism has a limited impact on the cooperative culture, and local governments play an important role. Accordingly, the local governments must actively formulate strategies to maintain and develop traditional agricultural industries and at the same time develop agrotourism activities. The government's ability to coordinate, cooperate, and participate reasonably is a key factor for the success of the sustainable development of the tourism industry. Conclusion: Based on coordination between stakeholders and a reasonable strategic direction, Yeongdong's agrotourism is being effectively deployed. The development of Yeongdong's agrotourism industry has achieved impressive results through an effective strategy, highlighting the important role of localgovernment in the consensus of local communities and collaboration with stakeholders. The role of outstanding local governments has been clearly demonstrated, especially in promoting, establishing, and contacting different organizations to effectively deploy agrotourism in the region.

This study experimentally investigates the flexural behavior of steel-UHPC composite slabs composed of an innovative negative Poisson's ratio (NPR) steel plate and Ultra High Performance Concrete (UHPC) slab connected via demountable high-strength bolt shear connectors. Eight demountable composite slab specimens were fabricated and tested under traditional four-point bending method. The effects of loading histories (positive and negative bending moment), types of steel plate (NPR steel plate and Q355 steel plate) and spacings of high-strength bolts (150 mm, 200 mm and 250 mm) on the flexural behavior of demountable composite slab, including failure mode, load-deflection curve, interface relative slip, crack width and sectional strain distribution, were evaluated. The results revealed that under positive bending moment, the failure mode of composite slabs employing NPR steel plate was distinct from that with Q355 steel plate, which exhibited that part of high-strength bolts was cut off, part of pre-embedded padded extension nuts was pulled out, and UHPC collapsed due to instantaneous instability and etc. Besides, under the same spacing of high-strength bolts, NPR steel plate availably delayed and restrained the relative slip between steel plate and UHPC plate, thus significantly enhanced the cooperative deformation capacity, flexural stiffness and load capacity for composite slabs further. While under negative bending moment, NPR steel plate effectively improved the flexural capacity and deformation characteristics of composite slabs, but it has no obvious effect on the initial flexural stiffness of composite slabs. Meanwhile, the excellent crack-width control ability for UHPC endowed composite members with better durability. Furthermore, according to the sectional strain distribution analysis, due to the negative Poisson's ratio effect and high yield strength of NPR steel plate, the tensile strain between NPR steel plate and UHPC layer held strain compatibility during the whole loading process, and the magnitude of upward movement for sectional plastic neutral axis could be ignored with the increase of positive bending moment.

In a good class, the elements that make up the class are organically related as a system. The goal of the class is to foster the ability of students to fully understand the educational content of the subject and then apply it to their professional areas. Therefore, for ideal classes, it is necessary to design students to acquire the necessary theories and apply them practically. The question We always ask ourselves during lectures is how to effectively give large-scale lectures for students. This is also the concern of all professors in charge of large-scale lectures opened across various major fields. Now is the time to find ways to effectively give lectures on a large scale. We studied how it is most effective to design and implement various factors such as lectures, presentation and group organization, assignment, group presentation, professor's group presentation guidance, lecture materials posting, questions and answers, group presentation feedback, final report writing, and grade calculation.

The purpose of this study is to analyse the cases related with PBL and to suggest the activation plan of LAI based on the derived results. The analysis objects were the PBL cases which have been performed from 2000 to 2018 in Korean schools. The PBL cases were analysed in the aspects of school levels, target grades, subject clusters, teaching patterns, information sources, cooperative teaching status, library cooperative teaching status, and educational effects. The results were like these; 1)The PBL was applied at the elementary schools the most, the next middle schools, and high schools. 2)The teaching pattern was the exclusive teaching the most, and the next pattern was team teaching with other teacher, and the lowest pattern was with librarian teacher. 3)The subject cluster was natural science cluster the most and the next was the human & social science cluster and the art, music and physical education cluster. 4)The PBL performed with school library was low. 5)The main effects of PBL were the improvements of academic achievement, learning satisfaction degree, creative ability, problem-solving ability, and self-directed learning capability. As the results, it's proposed that it's important for librarian teachers to have the aggressive attitude for the activation of LAI as well as the cooperation with PBL subject teachers from the planning step to the evaluation.
