Owing to raising number of livestock, we have a problem to solve disposal of livestock manure. We know that soil have the digestion ability of livestock manure as one of multifunctionality. I carried out to investigate of livestock manure digestion (especially pig and chicken manure) that is considered as nitrogen fertilizer in upland crops. The results were summarized as follows: 1. The amount of pig manure was(1999) 4,592,375 tons/year, and chicken manure was 4,488,166 tons/year and equivalent to 41,912 tons N/year and 76,223 tons N/year, respectively. 2. The definition of the digestion ability of livestock manure is as the maximum application amount of livestock manure without injuring soil and plant. And the calculation model of digestion ability of livestock manure(ALMD) is follows: ALMD = amount of nitrogen requirement per each upland crop / {(total nitrogen contents in livestock manure) ${\times}$ (nitrogen fertilizer efficiency of livestock manure)} 3. The amount of ability of pig and chicken manure for upland crops (dry based) were 1,142.9kg/10a and 540.1kg/10a, respectively. 4. The order of amount of digestion ability of livestock manure on upland were vegetables > orchards > miscellaneous grains(corn) > barley > potatoes > pulses > oil seeds & special crops ) fodder crops) mulberry.

This is the report of a case study to describe the results of applying an evaluation tool for communication ability when performing core basic nursing skills in fundamental nursing practice education. The communication ability evaluation tool was constructed based on a literature review and expert advice. The tool was applied to test 94 students who were taking fundamental nursing practice courses from October to November 2019. As a result, five factors (self-introduction, eye contact, emotional support, information provision, and therapeutic touch) were derived as evaluable items of communication ability to be evaluated when performing core basic nursing skill, and were evaluated when performing core basic nursing skills to measure vital signs. The average communication ability was 3.96 out of 5 points. According to the rubric, 95.8% of all students attained 'medium' and reached their goal achievement level. The findings of this study are meaningful in providing an important basis for improving the performance outcome evaluation process and for constructing a systematic evaluation system in fundamental nursing practicum. Further studies to secure the validity and reliability of this communication ability evaluation tool and comparative studies with various evaluation tools are suggested.

One of the goals of the new 2015 revised curriculum is to cultivate the creativity of students who will live in the era of the Fourth Industrial Revolution to create new things through diverse ideas and challenges based on basic learning skills. Accordingly, in order to solve the given problems rationally, the convergence problem solving ability that can process and utilize various areas of knowledge and information is becoming important. Therefore, in this study, we designed the integrative education using a 3D printer based on Tinkercad modeling and applied it to the class to investigate the effect on the improvement of computing thinking ability of elementary school students. To verify the contents of the study, two classes of 25 sixth-grade elementary school students were divided into an experimental group and a controlled group. For the experimental group, 12 classes of convergence education programs using a 3D printer were applied for about three months, and the same amount of general curriculum was conducted for the control group. After that, the t-tests were carried out using the pre-post test to measure the effectiveness of the computational thinking ability. After the application of the program, the experimental group showed statistically significant improvement in computational thinking ability, but the controlled group showed no statistically significant difference. The results show that convergence education using the Tinkercad modeling-based 3D printer has a positive effect on the improvement of computing thinking ability of elementary school students.

The purpose of this study is to develop a neuropsychological model for the spatial ability factor and to divide the brain active area involved in the light & shadow problem solving process into the domain-general ability and the domain-specific ability based on the neuropsychological model. Twenty-four male college students participated in the study to measure the synchronized eye movement and electroencephalograms (EEG) while they performed the spatial ability test and the light & shadow tasks. Neuropsychological model for the spatial ability factor and light & shadow problem solving process was developed by integrating the measurements of the participants' eye movements, brain activity areas, and the interview findings regarding their thoughts and strategies. The results of this study are as follows; first, the spatial visualization and mental rotation factors mainly required activation of the parietal lobe, and the spatial orientation factor required activation of the frontal lobe. Second, in the light & shadow problem solving process, participants use both their spatial ability as a domain-general thought, and the application of scientific principles as a domain-specific thought. The brain activity patterns resulting from a participants' inferring the shadow by parallel light source and inferring the shadow when the direction of the light changed were similar to the neuropsychological model for the spatial visualization factor. The brain activity pattern from inferring an object from its shadow by light from multiple directions was similar to the neuropsychological model for the spatial orientation factor. The brain activity pattern from inferring a shadow with a point source of light was similar to the neuropsychological model for the spatial visualization factor. In addition, when solving the light & shadow tasks, the brain's middle temporal gyrus, precentral gyrus, inferior frontal gyrus, middle frontal gyrus were additionally activated, which are responsible for deductive reasoning, working memory, and planning for action.

This study aimed to evaluate the microleakage and penetration of two hydrophilic sealants, Embrace $Wetbond^{TM}$ and Ultraseal $XT^{(R)}$ $hydro^{TM}$, when applied on dry and moist enamel, as compared to a conventionally used hydrophobic sealant, $Clinpro^{TM}$. A total of 60 sound human third molars were randomly divided into 5 groups according to the enamel moisture control and the sealant material used. After sealant application, the teeth were thermocycled and immersed in 1% methylene blue dye. Subsequently, the teeth were sectioned twice and the sections were examined using an optical microscope and image analysis software. Application of Embrace $Wetbond^{TM}$ on either dry or moist enamel resulted in more microleakage than $Clinpro^{TM}$. Application of Ultraseal $XT^{(R)}$ $hydro^{TM}$ on dry enamel showed a similar level of microleakage to $Clinpro^{TM}$, but application on moist enamel resulted in more microleakage. There were no significant differences between the groups in penetration. In conclusion, application of hydrophilic sealants on moist enamel did not improve the sealing ability and showed lower sealing ability than that of $Clinpro^{TM}$ applied on dry enamel.
