An intelligent distributed multi-agent system (IDMS) using reinforcement learning (RL) is a challenging and intricate problem in which single or multiple agent(s) aim to achieve their specific goals (sub-goal and final goal), where they move their states in a complex and cluttered environment. The environment provided by the IDMS provides a cumulative optimal reward for each action based on the policy of the learning process. Most actions involve interacting with a given IDMS environment; therefore, it can provide the following elements: a starting agent state, multiple obstacles, agent goals, and a cluttered index. The reward in the environment is also reflected by RL-based agents, in which agents can move randomly or intelligently to reach their respective goals, to improve the agent learning performance. We extend different cases of intelligent multi-agent systems from our previous works: (a) a proposed environment-clutter-based-index for agent sub-goal selection and analysis of its effect, and (b) a newly proposed RL reward scheme based on the environmental clutter-index to identify and analyze the prerequisites and conditions for improving the overall system.

The students in secondary schools have been taught calculus as an important subject in mathematics. The order of chapters-the limit of a sequence followed by limit of a function, and differentiation and integration- is because the limit of a function and the limit of a sequence are required as prerequisites of differentiation and integration. Specifically, the limit of a sequence is used to define definite integral as the limit of the Riemann Sum. However, many researchers identified that students had difficulty in understanding the concept of definite integral defined as the limit of the Riemann Sum. Consequently, they suggested alternative ways to introduce definite integral. Based on these researches, the definition of definite integral in the 2015-Revised Curriculum is not a concept of the limit of the Riemann Sum, which was the definition of definite integral in the previous curriculum, but "F(b)-F(a)" for an indefinite integral F(x) of a function f(x) and real numbers a and b. This change gives rise to differences among ways of introducing definite integral and explaining the relationship between definite integral and area in each textbook. As a result of this study, we have identified that there are a variety of ways of introducing definite integral in each textbook and that ways of explaining the relationship between definite integral and area are affected by ways of introducing definite integral. We expect that this change can reduce the difficulties students face when learning the concept of definite integral.

The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of Person-Centered Practice Inventory-Staff (PCPI-S) for nurses. Methods: The English PCPI-S was translated into Korean with forward and backward translation. Data were collected from 338 nurses at one general hospital in Korea. Construct validity was evaluated with confirmatory factor analysis, convergent validity, and discriminant validity. Known-group validity was also evaluated. Cronbach's α was used to assess the reliability. Results: The PCPI-S Korean version consisted of 51 items in three areas: prerequisites, the care environment, and person-centered process. The comparative fit index (CFI) and values of person-centered care process were improved after engagement and having sympathetic presence items were combined as one component. The construct validity of PCPI-S Korean version was verified using four-factor structures (.05 < RMSEA < .10, AGFI > .70, CFI > .70, and AIC). The convergent validity and discriminant validity of the entire PCPI-S question were verified using a two-factor structures (AVE > .50, construct reliability > .70). There was an acceptable known-group validity with a significant correlation between the PCPI-S level and the degree of person-centered care awareness and education. Internal consistency was reliable with Cronbach's α .95. Conclusion: The Korean version of PCPI-S is valid and reliable. It can be used as a standardized Korean version of person-centered care measurement tool. Abbreviation: RMSEA = root mean square error of approximation; AGFI = adjusted goodness of fit index; AIC = Akaike information criterion; AVE = average variance extracted.

Through this, we will identify prerequisites and strategies for Korean marine sports to become a global powerhouse, including revitalizing the Korean Wave for Chinese consumers. It also revitalizes global competitiveness and draws policy implications. Research design and methodology - Through interviews with experts and literature data, elements of important opportunities, threats, strengths and weaknesses of marine sports are summarized. Based on this SWOT, the AHP technique is applied to determine which is first and what is important between the factors that save opportunities and increase strengths, and measures to cope with threats and factors that complement weaknesses. Through this, the priority factor of experts suggests a plan for activating strategic marine sports. Results - First, the current status of marine sports in Korea and the perception of consumers are grasped through current data and literature research. Sub-elements are derived based on the theoretical literature on SWOT elements and opinions of experts. Prioritization is identified based on the AHP questionnaire of Korean experts. Conclusions - The strategy was derived through SWOT/AHP analysis, and the following implications were obtained. Regionally, Busan is psychologically and geographically adjacent to China and Japan. It is also an area where human exchanges are actively taking place along with the volume of imports and exports. Due to the increase in China's marine sports industry and population, it is necessary to expand the scope of Korea to marine sports beyond cosmetics, dramas, movies, and Korean waves (Hallyu) stars.
