The purpose of this study was centered on investigation of the effects N, P and K application rates on root yield and their available content (catalpol, sugar, ash and extracts) of Ji-whang(Rehmannia glutinosa Lib. var. purpurea Makino), and the current application rates(N 20kg/10a, $P_2O_5\;30kg/10a$, $K_2O\;20kg/10a$) was studied for Ji-whang production in Eui-sung Gun southeastern part of Korea Peninsular. The yields of fresh and dried rhizomas were 941-1,494 kg/10a and 251-385 kg/10a, respectively. The rhizoma yield increased highly with increasing the application amount of nitrogen more than 10 kg/10a, but the effects of phosphorus and potassium were observed only at the application level of 40 kg/10a and 20 kg/10a, respectively. Catalpol contents in rhizoma increased at the plot of 20 kg/10a application of nitrogen, but the effects phosphorus and potassium on the catalpol contents were not observed. Catalpol content in dried root increased with increasing N application more than 10 kg/10a. Fructose contents increased at the plot of 20 kg/10a and more N application, and galactose contents decreased with K application. With increasing N application, ash contents decreased, but ethanol extract contents increased.

These days UCC(User-created content) is being made and shared increasingly in entertainment and sports area, but its life cycle seems to be very short and the cases that it is used for an education or a learning purposes are not common yet. In this study a new methodology is suggested for adapting a UCC to a distance education. A teacher upload the movie that he or she made for the distance education system, so the students can carry out the self-centered learning procedure. After that, the students send their own movie files to the teacher, and get a feedback from the teacher as a evaluation of the course. In this study a distance education system was established as a prototype, and a short bamboo flute class was chosen for this study from the specialty developmental education program of the elementary school. According to the result of the questionnaire the students thought that their performance skill was improved a lot and they were satisfied with the learning program and the method of evaluation. They also answered that their skills dealing with a camera, a camcorder and a computer got much better. Moreover, most of the students thought that the relationships with their friends and their parents got better also because they spent lots of time together making and watching the movie files for this education program.

This paper describes nurses' perceptions toward parental participation in pediatric intensive care units (PICU). Qualitative data were collected from five nurses working at two PICUs in Seoul through individual in-depth interviews. The interviews were conducted from January to February 2016 and analyzed using traditional content analysis. Five categories were found for the parent participation in PICU: needs, attributes, benefits, barriers, and facilitating strategies for parent participation in PICU. Nurses acknowledged the necessities and benefits of parent participation, particularly in PICU, considering the parents' emotional burdens due to the critical health condition of their child as well as the limited visiting policy. The major barriers were a lack of knowledge and the skills of nurses to facilitate parent participation, nurses' heavy workloads, and lack of policies and guidelines supporting parent participation within the PICUs and hospitals. The participants indicated that organizational facilitating-strategies, such as education for nurses about meaning and skills of parent participation in PICU, raising awareness for nurses as well as parents, and ensuring professional staff dedicated to promoting parent participation, to be significant factors. Further study will be needed to develop nursing interventions to integrate parent participation in PICU care.

In this study, using a questionnaire about camp programs, we surveyed 375 gifted education institutes, including 285 classes for the gifted, 70 institutes for the gifted at education offices, and 20 institutes for the gifted at universities. The survey questionnaire consists of questions relating to camp design, camp operation, and camp introspection. The questions relating to camp operation are subdivided into questions relating to content, process, product, and learning environment of the camp. In the analysis of camp design, experience-centered camps entailing visits to research institutes, science museums, and so on showed the highest ratio. The camps were generally carried out in summer vacation as two day/one night programs. The average score of camp content was 3.72, that of camp process was 3.78, that of camp product was 3.77, and that of camp environment was 3.58. In the analysis of camp introspection, the item 'a lack of information about diverse camp activities' showed the highest difficult thing. Integrating these results, we suggest that information about diverse camp activities should be developed and supplied and the camp environment strengthen the freedom of students to select camp activities.

The purpose of this study was to explore the components of the geriatric robot pet, which might be helpful in caring for elderly people in the future. Focus group interview-with two focus groups-was performed between August 2014 and December 2014. Study participants were 13 geriatric experts from nursing, medicine, social work, and physical/occupational therapy. All interview data were transcribed, followed by debriefing and a qualitative content analysis. Three main themes emerged: acknowledgment of the usefulness of geriatric robot pet, establishment of elderly-centered appearance, and the functions of the robot pet to meet the needs of elders and family members. The robot pet was considered to be useful to elders who live alone since they can benefit from companionship and care provided by the robot pet. Geriatric robot pet needs to be manageable in size and weight, like a small dog. Moreover, a function that allows for interaction with and monitoring the elderly would be beneficial. The baseline elements that could guide further development of contents for the Korean geriatric robot pet were proposed from the results of FGI. Studies that validate these elements are necessary.

As the core technology of the Fourth Industrial Revolution, AI is applied to various fields of society(e.g. politics, culture, industry, economy, etc.) and causes revolutionary changes. Students who will lead the age of AI need the ability to recognize social changes due to AI, acquire AI related knowledge and utilize AI in various situations. However, it is difficult for elementary school students to understand the concept and principles of AI. Therefore, this study developed an AI education program by selecting educational contents and methods appropriate to the level of elementary school students, and investigated the educational effects of the program by applying it to an actual educational setting. The content selected in this study is 'Social Awareness on AI', 'Understanding AI' and 'Utilizing AI', and eight content elements were selected. To help students learn AI easily and pleasantly at their level, activity-centered education, convergence of subjects and project-based learning were selected as instructional methods, and 20 sessions of education program were developed and implemented. In addition, the effects of the program were analyzed concerning 'perception on AI', 'convergent thinking', 'creative problem-solving' and 'collaboration capability', and positive changes were verified for all four aspects.
