  • Few observation have been made on the pericardial pressure and little is known about the composition of he pericardial fluid. So we studied the basic qualitative and quantitative analysis of the pericardial fluid in the patients with cardiac disease either congenital heart diasese(group A) or acquired heart disease(group B). The pressure of the pericardial cavity was measured by the method of open tipped water filled small polyethylene catheter connecting to the standardized monitor, which was introduced into pericardium of the patients who were performed pericardial incision for the heart or pericardial surgery. All of the data was compared to the simultaneously checked hematologic value of the same patient. The mean pressure of the pericardial cavity was 2.4mmHg and the amount of the pericardial fluid was 13cc/m2 of body surface for the group A and 17.7cc for the group B. And the cell count was 138$\pm$l16/1 in group A and 230$\pm$135/1 in group B and the pH was 7.83$\pm$0.40 in group A. 7.80$\pm$0.52 in group B. Pericardial fluid revealed satisfactically significant alkaline pH than plasma. The fundamental electrolyte, Wa+, K+, Cl and glucose were identical to the hematologic values of the same patient, but the protein concentration was 2.Bg/dL for group A and 3.Ig/dL for group B heart disease and those were remarkable low concentration compared to the hematologic value of the same patient. LDH and amylase were identical to the value of the serum of the same patient, but the concentration of LDH of group B was slightly higher than that of the group A.

  • 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 Coronavirus disease 2019 (COVID-19) became a pandemic, most nursing departments in Korea implemented online non-face-to-face practices rather than the existing practice method. This study was a qualitative study that analyzed the reflection diaries written by participants to understand what they experienced in the online non-face-to-face adult nursing practice process. The online non-face-to-face adult nursing practice was 90 hours for two credits and nine hours per day for a total of 10 days. This online practice consisted of computer-based simulation practice, computer-based nursing skills practice, video and educational material production, real-time online quiz, online lecture video, and discussion. As a result of analyzing the reflection diary, six categories, 13 subcategories, and 33 codes were derived. The six categories were 'Experience of various situations', 'Experience of new study', 'Fulfillment for the clinical practice', 'Building relations with professors', 'Fear of being a pre-nurse', and 'Ambivalence for the non-face-to-face practice'. These results are significant in that in the post-corona era, adult nursing practice was conducted as a non-face-to-face practice rather than a clinical practice institution, and various educational methods were operated. This study is expected to provide important basic data for the development and operation of non-face-to-face adult nursing practice.

  • The purpose of the study is to find creativity factors of students in the process of small group modeling and relate them to the types of interactions among students. In order to capture students' detailed interactions, this study was conducted as an 'essential case study' through qualitative analysis. We have developed the modules of nine lessons about terraforming, and they were used in an actual classroom. In order to understand the creativity of the students in the process of modeling, students' discourses and interview data were analyzed using 19 creative factors or abilities. The findings are as follows. Frequently found creativity factors are Elaboration, Evaluation, Visualization, Resist premature closer, Originality, Analysis and Concentration. And students' interactions that affect students' creativity in the process of modeling can be classified into four categories: Suggestion, Agreement, Questioning, Refutation, and Conversion. Through each interaction, students demonstrated the process of expressing and modifying their own thoughts and ideas in the modeling process. The findings of the study suggest that it is important to the teachers to understand types of interactions among students and the relationship between the types of interaction and creativity factors for students' creative modeling in modeling-based learning.

  • The purpose of this study is to analyze the effect of youth activities on adolescents' sense of community using "Korean Children & Youth Panel Study" data collected by the National Youth Policy Institute. Especially, this study tried to reflect various aspects of youth activities, such as participation in activities, number of types of activities, and satisfaction with activities. Also, this study paid particular attention to examining the cumulative effect of youth activities. The main results are as follows. First, the participation of youth activities, the satisfaction level of experiential activities, and the number of kinds of experiential activities varied according to income level and regional scale. Next, the results of the OLS regression analysis on adolescents' sense of community show that participation in youth activities, number of kinds of activities that participated in, and satisfaction with activities during the first-year of high-school all influence adolescents' sense of community. On the other hand, the results of analysis of the effects of cumulative experience during middle school during middle school shows that it is difficult to ensure long-term effects by only participating in youth activities. Positive effects persisted only when adolescents participated in high quality youth activities during middle school. The results of this study show that the qualitative aspects of youth activities are important for sustaining the effectiveness of youth activities.

  • Due to high proportion of exports, Korea has a higher dependence on the global value chain (GVC) than other major developed countries. This reason, Korea has a structure that is sensitive to GVC changes. This is because Korean exports are concentrated on specific countries and items, and most of the materials for export tend to depend on imports. Currently, export restrictions resulting from trade disputes with Japan can affect the industry of Korea as a whole due to the supply of core materials. Therefore, in order to minimize economic damage caused by export regulations in the current situation, it is necessary to reorganize the GVC, through efforts to rapidly diversify imports and localize imports that depend on Japan. To this end, it is necessary to derive and classify imported goods that depend on Japan, and to localize items that are difficult to diversify imports, and prompt R&D investment is required for this. This study aims to support R&D investment policy through quantitative analysis based on big data rather than a decision-making method based on expert-centered qualitative analysis.

  • Background: The Unani system of medicine has been practised since centuries for the treatment of a range of diseases. In spite of their efficacy they have been widely criticised due to the lack of standardization and poor quality control. Standardization of Unani medicine is a valuable issue at the present because they are very prone to contamination, deterioration, adulteration and variation in composition due to biodiversity as well as careless collection. Objective: To Standardize and Development of HPTLC Fingerprinting of a polyherbal Unani formulation Qurs-e-Safa. Materials and methods: The conventional and modern analytical techniques were used to standardise Qurs-e-Safa. The study was carried into three different batches of Qurs-e-Safa prepared with its ingredients. The parameters studied are organoleptic, microscopic, physicochemical parameters, phytochemical screening, TLC, HPTLC profile, aflatoxin, microbial load and heavy metal analysis. Results and conclusion: Qurṣ-e-Sa'fa is dark yellow in colour and aromatic smell. Uniformity of diameter and weight variation were found to be 13 ± 0, and 524.7 ± 1.72 mg. friability, hardness and disintegration time of all 3 batches were found to be (0.0615 ± 0.004, 0.0885 ± 0.0047 and 0.0725 ± 0.0058), (3.5 ± 0.2886, 3.67 ± 0.1674 and 3.67 ± 0.1674) and (16 to 17 minutes). Extractive value were found to be maximum in distilled water (38.488 ± 0.20, 37.3824 ± 0.38 and 39.8177 ± 0.13) followed by alcohol (27.5406 ± 0.54, 27.5656 ± 0.32 and 26.9229 ± 0.25). Loss of weight on drying, pH, total ash, acid insoluble ash, qualitative test was set in. Phytochemical screening revealed the presence of Carbohydrates, Phenols, Resins, Proteins, Steroids, fixed oil and Flavonoids. The microbial load was found absent and heavy metals were within permissible limits. The data evolved from the study may serve as a reference to validate and also help in the quality control of other finished products in future research.

  • To understand the research trends of English education in Korea for the last 20 years from 2000 to 2019, 12 major academic journals in Korea in the field of English education were selected, and bibliographic information of 7,329 articles published in these journals were collected and analyzed. The total number of articles increased from the 2000s to the first half of the 2010s, but decreased somewhat in the late 2010s and the number of publications by journal has become similar. These results show that the overall influence of English education journals has decreased and then leveled in terms of quantity. Next, 34 topics were extracted by applying latent Dirichlet allocation (LDA) topic modeling using the English abstract of the articles. Teacher, word, culture/media, and grammar appeared as topics that were highly studied. Topics such as word, vocabulary, and testing and evaluation appeared through unique keywords, and various topics related to learner factors emerged, becoming topics of interest in English education research. Then, topics were analyzed to determine which ones were rising or falling in frequency. As a result of this analysis, qualitative research, vocabulary, learner factor, and testing were found to be rising topics, while falling topics included CALL, language, teaching, and grammar. This change in research topics shows that research interests in the field of English education are shifting from static research topics to data-driven and dynamic research topics.
