This study identified the relationship between empathy, tangibility, certainty, reliability, and educational satisfaction, which are sub-factors of educational service quality, and analyzed how educational service quality affects educational satisfaction through the moderating effect of mentoring. A total of 381 response samples were constructed for empirical analysis to analyze demographic characteristics, student use patterns, validity and reliability, correlation, and hypothesis verification, and a total of six hypotheses were established and verified using variables selected based on previous studies and preliminary surveys. First, as a result of the verification of Hypothesis 1, it was found that all constituent factors of education service quality had a positive (+) significant effect on education satisfaction. Second, as a result of the moderating effect of mentoring in Hypothesis 2, it was found that education satisfaction was increased in the confidence, reliability, and mentoring of education service quality. Therefore, empathy, tangibility, certainty, and reliability of education service quality are factors necessary to increase education satisfaction, and academy operators and managers are required to reflect this and operate strategies to increase the competitiveness of the academy.

The aim of this study was to analyze a group of pre-service elementary teachers experience on the cognitive terms of biology inquiry subjects, and experience on living materials related with the domain of life in the Korea elementary school science textbook. Firstly, elementary school pre-service teachers had the confidence of inquiry subjects related with the domain of life such as 'when we take breath what will happen in human body?' and 'Can we make the model of human body?' But they did have the most diffidence of 'The search for pieris rapae, a cabbage butterfly's life', 'Can we grow the little creature?' The reason why pre-service elementary teachers had diffidence of comprehending experiment procedure and planning ability was that 'they focused on understanding the scientific concepts instead of planning experiments by themselves', and 'they carried out the least amount of experiments' Secondly, elementary school pre-service teachers had never experienced biology materials related with the domain of life in the Korea elementary school biology science textbook such as 'tradescantia reflexa', 'Caddis larva', 'hydrilla verticillata', and 'Plantain lily.' According to the findings obtained from the study, the reason why they had never seen the biology materials was that they had the least opportunity of immediately observing life creatures due to memorization-intensive classes.

In this study, we analyzed the food components in the release product that sampled Sinonovacula constricta from the foreshore littoral at Byeongnyang-myeon, Suncheon Bay. We used microscopy and next-generation sequencing (NGS) to evaluate the applicability of morphological and molecular methods to analyze release products. The higher species diversity observed in the NGS method is due to the different levels of species identification, as microscopy displays morphological and anatomical levels of plankton species identification in S. constrita. Moreover, NGS can identify the level of species in the organic matter by using the 18s_V9 primer.

This study was conducted with 92 people who participated in the online self-introduction consulting program operated for 3 weeks in August, 2020 at a university. This is a study to find out whether the application of the online self-introduction consulting program helped prepare for employment. As a result of the study, there was not enough self-introduction to be written in advance or the employment target organization was not clear. After participating in the online self-introduction consulting program, it was very helpful in preparing for employment, and the service utilization of the related self-introduction program was high. They responded that a series of questions about the templates in the program helped to write the self-introduction letter. It was said that the interview preparation process is necessary as a necessary job support education

The aim of this study was to identify the performance and requirements of the visiting nursing care using Omaha system in public health center. The highest performance were 'personal hygiene', 'pain', 'medication regimen', 'nutrition', 'physical activity', 'sanitation', 'sleep and rest patterns', 'oral hygiene', 'mental health' in order. The lowest performance were 'sexuality', 'postpartum', 'income', 'family planning', 'pregnancy', 'spirituality', 'abuse', 'reproductive function', 'neglect' in order. Problems such as 'postpartum', 'pregnancy' and 'family planning' need to strengthen the role of visiting nurses according to the region. this result will be the basis for visitung nursing care.

Perception of the experiment is one of the most important factors of students' understanding of scientific inquiry and the nature of science. This study examined the perception of middle and high school students of the meaning of 'experiment' in the biological sciences. Semantic network analysis (SNA) was especially used to visualize students' perception structure in this study. One hundred and ninety middle school students and 200 high school students participated in this study. Students responded to two questions on the meaning of 'experiment' in science and biology. This study constructed four semantic networks based on the collected response. As a result, middle school students about the 'experiment' in science are 'we', 'direct', 'principle' of such words was aware of the experiments from the center to the active side. The high school students' 'theory', 'true', 'information' were recognized as an experiment that explores the process of creating a knowledge center including the word. In addition, middle school students relative to 'experiment' of the creature around the 'dissection', 'body', high school students were recognized as 'life', 'observation' observation activities dealing with the living organisms and recognized as a core. The results of this study will be used as important evidence in the future to map out an experiment in biological science curriculum.

The aim of this study is selection of the male-sterile plant for inhibiting transgene flow through gamma-irradiation ($^{60}Co$) at the pollination and fertilization cycle of herbicide-tolerant genetically modified (GM) zoysiagrass (Zoysia japonica Steud.). High frequencies of plant mutations were obtained about 18% from $M_1$ generation at the doses (10 to 50 Gy). We also found that some $M_1$ plants showed male-sterile plants using de-husked seeds and comparison of stainable pollen using $KI-I_2$ solution. Besides the effects of irradiation on pollination and fertilization cycle, various other mutations like dwarf, cold tolerance, increasing grains and mass were observed. Four of dwarfism plants were selected through comparison of morphological characteristic between control and mutants during 4 years. These results demonstrated that the gamma-irradiation on pollination and fertilization cycle is very effective to induce the various mutations, and the male-sterile mutants are useful for controlling transgene flow and developing of high quality turfgasses.

The Oriental flower arrangements have the beauty of a strict triangle in a symmetrical three-dimensional effect as the form of flower tribute to gods in ancient times and used frogs to fix flowers to a basin easily. Flower arrangements of a conical shape made by repeatedly piled flowers in ancient Egypt shows the origin of the present vertical form of the Western flower arrangements. Flower arrangements in ancient Greece formed in a smooth S shape, while Roman flower arrangements were rich and gorgeous in a lowering and thin shape horizontally. Persians were showing triangular forms similar to the Oriental three-dimensional effect. The basic form of flower arrangements in the age of Renaissance was also created upon the ancient one, descending to Art Nouveau when flower arrangements were widely expressed from mass to space aesthetics led by America in the 20th century influenced by mild color, simplicity and realistic description of the Oriental art in the late 19th century. The Western flower arrangements are focused on formation, same as the Oriental ones, yet they disregard naturality and based on practicality.
