Various robot platforms have been designed and developed to perform given tasks in a hazardous environment for the purpose of surveillance, reconnaissance, search and rescue, and etc. We have considered a terrain adaptive hybrid robot platform which is equipped with rapid navigation on flat floors and good performance on overcoming stairs or obstacles. Since our special consideration is posed to its flexibility for real application, we devised a design of a transformable robot structure which consists of an ordinary wheeled structure to navigate fast on flat floor and a variable tracked structure to climb stairs effectively. Especially, track arms installed in front side, rear side, and mid side are used for navigation mode transition between flatland navigation and stairs climbing. The mode transition is determined and implemented by adaptive driving mode control of mobile robot. The wheel and track hybrid mobile platform apparatus applied off-road driving mechanism for various professional service robots is verified through experiments for navigation performance in real and test-bed environment.

The discourse on the lockdown in Indonesia is getting stronger due to the increasing number of positive cases of the coronavirus and the death rate. As of August 12, 2020, the confirmed number of COVID-19 cases in Indonesia reached 130,718. There were 85,798 victims who have recovered and 5,903 who have died. Data show a significant increase in cases of COVID-19 every day. For this reason, there needs to be an evaluation of the government policy of the Republic of Indonesia in dealing with the COVID-19 pandemic in Indonesia. An evaluation of policies for handling the pandemic must include public opinion to determine any weaknesses of this policy. The development of public opinion about the lockdown policy can be understood through social media. During the COVID-19 pandemic, measuring public opinion through traditional methods (surveys) was difficult. For this reason, we utilized big data on social media as research data. The main purpose of this study is to understand public opinion on the lockdown policy in overcoming the COVID-19 pandemic in Indonesia. The things observed included: volume of Twitter users, top influencers, top tweets, and communication networks between Twitter users. For the methodological development of future public opinion research, the researchers outline the obstacles faced in researching public opinion based on big data from Twitter. The research results show that the lockdown policy is an interesting issue, as evidenced by the number of active users (79,502) forming 133,209 networks. Posts about the lockdown on Twitter continued to increase after the implementation of the lockdown policy on April 10, 2020. The lockdown policy has caused various reactions, seen from the word analysis showing 14.8% positive sentiment, 17.5% negative, and 67.67% non-categorized words. Sources of information who have played the roles of top influencers regarding the lockdown policy include: Jokowi (the president of the Republic of Indonesia), online media, television media, government departments, and governors. Based on the analysis of the network structure, it shows that Jokowi has a central role in controlling the lockdown policy. Several challenges were found in this study: 1) choosing keywords for downloading data, 2) categorizing words containing public opinion sentiment, and 3) determining the sample size.

In this paper, an air conditioner peak power control system using electric power line communication has been developed. The air conditioner power control system using RS-485 communication method is hard to install on the existing buildings due to difficulty in cabling, and the system using wireless communication methods has a weak point of not being able to be used in close space, while the developed system has its own advantages of overcoming the above mentioned obstacles. In addition, the system is extended to support not only single-phase electricity system but also three-phase four-wire electricity system, and therefore can be installed anywhere in the domestic environment. The system also has enhanced the ease of deployment, operational stability and economical efficiency by compact circuit design. Considering the current state requiring the energy sayings, the system would greatly contribute to the widespread use of the air conditioner power control system. The superiority in the performance and stability of the system has been proved by the design verification of each component such as remote air conditioner controller, electric power line gateway and so on, and the field test of the whole system.

In the midst of a continued discourse and development concerning design education and its impact on innovation and creativity, I believe that design education still holds the key to enhancing design methodology while increasing creativity by having students take on several creative roles in an interactive and enjoyable studio course. Clearly, there exist impediments that block the creative process in our standard track in design education; however, a course entitled "The Creative Workshop" can overcome such obstacles. Through this course, a student can learn the essential skills of a designer: inventive thinking, a sense of aesthetics, and a spirit of collaboration. In addressing each of the three essential elements, this course has devised role-plays in the way of projects. Simply put, students will be required to demonstrate and, therefore, express their unique creativity that may have otherwise gone muted. Such creative expression can take form in a low stakes, open forum that heralds the invaluable attribute in design such as creative freedom. As a result, the true spirit of creativity is fostered rather than mere aesthetics and styling. Moreover, through role plays, the focus shifts its center from design, allowing each student to explore the uncharted areas of one's own creativity which may come naturally to some extend while disconcerting to others. It may prove particularly uncomfortable for Korean students whose ideas about education have been directly connected to the strict and regimented school system that stresses adherence to standardization such as the national college entrance exam. This course, therefore, is aimed stretch the scope and scale of students' creativity as they learn to collaborate on role plays, utilizing diverse skills from various disciplines.

This study explored how young people with disabilities experience self-determination in their lives. This study employed a grounded theory approach involving 10 undergraduate students with cerebral palsy or physical disabilities, in their early 20's, and individual interviews. The experience relating self-determination of the participants seemed to start with "wanting to do things at their will as they grow up". The participants reported experiencing "yearning to attain self-actualization overcoming disabilities" in the context of "disability-related social limitation", "divided opinions between the participants and their parents", and "limitation in financial and psychological resources". The emerging strategies to attain self-actualization included "active coping", "avoiding confrontation", and "conditional acceptance". Intervening conditions to formation of the strategies included ”challenging spirits towards prejudice about disability", "autonomous tendencies", "taking the most of social support" and "parenting attitudes of their parents". In the process of seeking to attain self-actualization, these participants experienced "self-maturation" and "the sense of guilt towards their parents". The findings emerged from the study was that there are three stages in the process young people went through in self-determination. The stages consist of "perceiving their needs and obstacles for self-determination", "problem solving", and "perceiving their growth". In addition, four self-determination patterns are derived from this data: "breaking through", "multi-strategic", "moderate", and "acceptive". This study suggested some theoretical and prctical implications needed to facilitate self-determination of youth with disabilities.

The importance and necessity of convergence research to solve complexity and diversity of research problems is more increasing. For successful convergence research, connectivity beyond the boundary and distance between disciplines is a key factor. To understand the current status and characteristics of connectivity among researchers, we investigated the interdisciplinary relationships among 487 researchers' disciplines in a university by using network anaylsis. The results showed that (1) connectivity between similar disciplines were higher than different disciplines, (2) the density and cohesion level of connectivity within the same campuses were higher, and (3) network centrality was concentrated in engineering and medicine. Based on these results, the necessity of overcoming boundaries and distances as obstacles to convergence research and the necessity of diversification of centrality were proposed. While previous studies mainly analyzed the research outcomes, this study is meaningful because it analyzed researchers' connectivity and collaborative structures in the actual convergence research procedures.

In this paper, fuzzy-ARTMAP equalizer is developed mainly for overcoming the obstacles, such as complexity and long training, in implementing the previously developed neural-basis equalizers. The proposed fuzzy-ARTMAP equalizer is fast and easy to train and includes capabilities not found in other neural network approaches a small number of parameters, no requirements for the choice of initial weights, no risk of getting trapped in local minima, and capability of adding new data without retraining previously trained data. In simulation studies, binary signals were generated at random from linear channel with Gaussian noise. The performance of the proposed equalizer is compared with other neural net basis equalizers, such as MLP and RBF equalizers. The fuzzy ARTMAP equalizer combines relatively simple structure and fast processing speed; it gives accurate results for nonlinear problems that cannot be solved with a linear equalizer.

This study was conducted in 2008 with 80 in-service mathematics teachers. We took a course that was consisted of a lecture and a practice on Socrates' method. In our study, mathematics teachers conducted making a teaching plan by using Socrates' method. But we became know that we need to offer concrete ideas or examples for mathematics teachers in order to apply Socrates' method effectively. Therefore we tried to search for educational methods in using Socrates' method to teach school mathematics. After investigating of preceding researches, we selected some examples. On the basis of these examples, we suggested concrete methods in using Socrates' method. That is as follows. Socrates' method need to be used in the context mathematical problem solving. Socrates' method can be applied in the process of overcoming cognitive obstacles. A question in using Socrates' method have to guide mathematical thinking (or attitude). When we use Socrates' method in the teaching of a proof, student need to have an opportunity to guess the conclusion of a proposition. The process of reflection revision-improvement can be connected to using Socrates' method.
