Farming activities are transforming from traditional skill-based agriculture into knowledge-based and technology-driven digital agriculture. The use of intelligent information and communication technology introduces the idea of smart farming that enables farmers to collect weather data, monitor crop growth remotely and detect crop diseases easily. The introduction of Plantix, a pest and disease management tool in the form of a mobile application has allowed farmers to identify pests and diseases of the crop using their mobile devices. Hence, this study collected the reviews of Plantix to explore the response of the users on the Google Play Store towards the application through Latent Dirichlet Allocation (LDA) topic modeling. Results indicate four latent topics in the reviews: two positive evaluations (compliments, appreciation) and two suggestions (plant options, recommendations). We found the users suggested the application to additional plant options and additional features that might help the farmers with their difficulties. In addition, the application is expected to benefit the farmer more by having an early alert of diseases to farmers and providing various substitutes and a list of components for the remedial measures.

This study aims to study the change in the level of awareness of medical personnels regarding the patient safety culture(PSC) before and after the Leadership WalkRounds(LWR). The LWR in this study was based on the IHI and the models of the Patient Safety Rounds(PSRs) at University of Michigan, emphasizing the 5 steps of Preparation--Scheduling--Conducting--Reporting--Resolving. After the LWR the scores for the level of awareness showed a statistically significant increase from 2.63 to 3.36(p<.001). Among the participants, those who are pharmaceutists, women, 30.0~39.9 years old, or had work experience of a year or less showed particularly notable increase in awareness. The effect was significant across all categories of PSC, especially in Safety Accident Reporting(p<.001), then in Communication(p<.001). Therefore the LWR proved an convergent concept for applying new leadership skill and the concept of patient safety management as an method to elevate the frontline staffs' awareness of PSC.

As future society will be strengthened by interdisciplinary study and education, we have to prepare general education curriculum which provide critical thinking, problem-solving, creativity, communication abilities. Those curriculum will help to nurture students who lead our future society. Now we prepare new curriculum to train students to understand the computer science and software needed to create their own, and we could cultivate students having ability to create interdisciplinary study by using programming skill. So we ran a computer programming class during a semester for the freshmen's capacity building on computing-thinking ability using the Python language. We analyzed the effectiveness and showed that student's curiosity and motivation to want to learn computer programming occurred, their various skills for interdisciplinary ability were improved.

The purpose of this study is to the relation between the focusing manner and clinical competence and to determine the effect of the focusing manner on clinical competence. In December 2018, data were collected from 189 university students in the nursing department and analyzed using a multiple regression. As a result, major satisfaction and focusing manner of nursing university students were identified as major factors influencing clinical competence. In particular, 'expressing', a sub-factor of the focusing manner, had a significant effect on the sub-factors of clinical competence ability, 'nursing process, nursing skill, teaching and cooperation, interpersonal relationships and communication, and professional development', and explanatory power was 15.7%~19.9%. Therefore, during the undergraduate course, it is suggested that university students in the nursing department actively develop teaching-learning methods along with the development of a program to improve 'the ability to express appropriately for the situation'.

The purpose of this study is to set the relationship between each parts that forms the engine of an automobile based on the 3D visualization technology which is able to be learned according to the skill of the operator in the industry field and to recommend the auto parts using a task ontology. A visualization method was proposed by structuring the complex knowledge by signifying the link and the node in forms of a network and using SOM which can be shown in the form of 3 dimension. In addition, by using is-a Relationship-based hierarchical Taxonomy setting the relationship between each of the parts that forms the engine of an automobile, to allow a recommendation using a weighted value possible. By providing and placing the complex knowledge in the 3D space to the user for an opportunity of more realistic and intuitive navigation, when randomly selecting the automobile parts, it allows the recommendation of the parts having a close relationship with the corresponding parts for easy assembly and to know the importance of usage for the automobile parts without any special expertise.

Early diagnosis of autism and intervention of medical treatment are very significant to develop specific social communication skill for children with autistic spectrum disorders (ASDs). But they have difficulties in medical treatment because of lack of a public welfare institution and special medical system. In particular, few children can access such treatment and the existing single-therapist clinics are inefficient with regard to cost and time. Therefore, new methods should be studied for developing various products, services, and systems for autistic children. This study discusses the potential use of an interactive design as assistive technology for such children. We utilize the experience gained in the collaborative design of the interactive therapy system (ITS). The key methods include a collaborative design with rapid interactive prototyping, heuristic evaluation, user-centered process, VR technology, tangible interface, and scenario-based contents. We applied these methods to the ITS and proved the efficiency of interactive design as an assistive technology through clinical experimentation.
