Tactile sensors, which are commonly referred to as pressure and strain sensors, have been extensively investigated to meet the demands for attachable and wearable electronics for monitoring the health status or activity of human users. For this purpose, the introduction of two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs) with high mechanical strength at the atomic scale is very suitable for tactile sensors applicable for use in human-friendly devices. In this paper, we examine a descriptive summary of a tactile sensor and review state-of- the-art research trends of 2D material-based tactile sensors in terms of the material and architecture. Finally, we propose a roadmap for future studies into advanced tactile sensors based on our ongoing research.

In the maritime industry, the convergence of information and communication technology (ICT) occurs in two areas. The first one is the convergence of e-navigation technology to apply ICT to the maritime domain. This was led by EU's initiative and is also being promoted in our country. The other one is the convergence of autonomous ship technology to apply various ICT technologies for commercial purposes. This initiative is being led by maritime industries. In this paper, we describe trends of e-navigation and maritime autonomous surface ship technology convergence. Subsequently, we explain the standardization status of performance and technical standard bodies, international standardization organizations, and related standard-developing organizations to provide the interoperability of these technologies. Finally, we examine ongoing projects in Korea and suggest future directions for their R&D and standardization.

In education, innovative ways of teaching and learning are always under development and keep being proposed with advanced concepts since the ancient times. Student-centered learning, problem-based learning and cooperative learning have been three major trends under development in secondary education research and practice more than a decade or so. Combined with advanced information and communication technologies, these trends will greatly transform the way we teach and learn in classroom environment and may change the classroom environment itself, into a more interactive and self-centered coaching type environment. In this study, a smart environment that utilizes advanced information technology devices and network is conceptualized, accommodating requirements contained and proposed in the recent trendy pedagogies. Pedagogical cases discussed in these trends are analyzed in detail, producing requirements for such a learning and coaching environment. These requirements are modeled using unified modeling language, leading to a proposal of a basic architecture for an information system supporting this environment.

Nanotechnology has been applied to various fields in our life. Although there is a limitation of nanoparticle monitoring so far, it is expected that nanoparticles are widely distributed in environmental multimedia. Nanoparticle is known to be more toxic than its corresponding bulk material. For this reason, developed countries and international organizations are preparing for future regulation. To evaluate the safety of nanoparticles, nanotoxicity studies are internationally underway. In this study, we evaluated the research trends of ecotoxicity of nanoparticles in water environment. Test species include fish, water flea, and algae. Nanoecotoxicological studies are rapidly increasing and the experimental designs become more sophisticated. Physicochemical properties of nanoparticles should be measured and the ionization potential is important for metal-based nanoparticles. We analyzed the research trends based on the type of nanoparticles and test species. Also experimental aspects of nanoecotoxicology are considered.

The purpose of this study was to analyze the research trends on effortful control with a focus on those found in academic journals. This was done in an attempt to understand the conception of effortful control clearly and lay the foundations for future studies. An analysis was performed on frequencies by years, methodology, and content. Results showed that (1) 95 research articles on effortful control were published between January of 1999 and June of 2010. (2) Most research participants were school-aged children. (3) There were a number of ways that researchers have assessed the concept of effortful control, and the most frequently used measurement scale was the Rothbart's questionnaire for temperament. (4) The main content of the research was the relationships between effortful control and developmental domains (particularly, emotional and social development). More recently, researches examining environmental factors including family and peer environment have increased.

The purpose of this study is to investigate trends of characteristics and changes in the field of marine/naval/underwater military science and technology in Korea. This study analyzed the keywords that appeared in marine/naval/underwater section of the "Journal of the Korean Military Science and Technology" during the period, 1998~2012. One hundred and seven articles were analyzed by keywords in English. Four hundred and fifty four keywords in English were analyzed by appearance frequency. Finally those results of source literatures and keywords were compared with each other and a better direction for the future of the field with further studies was suggested.

Purposes: This study aims to investigate the number of cataract surgeries and predict future trends using 13-year data. Methodology: Trends investigation and comparison of prediction methods was conducted to determine better prediction model using Major Surgery Statistics from Korean Statistical Information Service in 2006-2018. ARIMA(Auto Regressive Integrated Moving Average) was selected and prediction was conducted using R program. Findings: As a results, the number of surgeries will continue to increase. The trends was predicted to increase during January-April, and it declined over time and was the lowest in August. Pratical Implications: Therefore, it is necessary that management will be needed by continuously investigating and predicting the demand and trend for surgery to prepare an alternative to the increase.

Objectives: The purpose of this study was to identify the domestic research trends in health education published in journals and dissertations, and to provide recommendations for quality improvement. Methods: 277 papers published from 1960 to 2009 were reviewed using criteria of analysis. The results were displayed as frequencies and percentages. Results: The contents of the health education were very poor compared with the Health Promotion Act. In health education program developing and evaluation process, papers on the assessment stage occupied the largest portion. In research methodology; the survey study, school field, the questionnaire research tool and inferential statistics were the most applied. Master theses were the largest number. Conclusions: This review suggests that the published papers, in some instances, have been poorly done. However, this study may provide future guidelines for health education research, and it is hoped that higher level research can be accomplished.

Objective: The purpose of this study was to explore research trends in childhood executive function in Korean academic journal articles. This study showed which population groups were studied, which factors of executive function were measured, and which domains were studied in the selected articels. Methods: A systematic review of empirical studies of childhood executive function published in Korean academic journals from 2006 to 2016 was conducted. Through searching the KERIS database, 60 empirical studies were selected for review. Results: The results of the analyses showed that the population group the most studied was normal young children and that factors of executive function most studied were inhibition, cognitive flexibility, and working memory. Conclusion: Based on this systematic review of empirical studies of childhood executive function, several suggestions for future research are addressed.
