This study analyzed the phenomenological research method of Giorgi in order to understand the changes in the self-esteem of middle-aged women through group bibliotherapy. During this study, 12 sessions were conducted for six middle-aged women, and the participants' statements in the recorded files were analyzed and integrated into 221 semantic units, 16 sub-situations/topics, 6 situations/topics, and 3 groups. During the research, the participants suffered from neurosis symptoms due to family difficulties. Nevertheless, bibliotherapy showed favorable results; the use of picture books and thus the interaction between the participants led to positive, emotional and psychological responses. Furthermore, from the study, it was concluded that religious life played an important role in healing the participants' wounds.

Creeping bentgrass (Agrostis stolonifera L.) is economically important as the principal turfgrass species for golf course greens and fairways in temperate climates around the world. As the utilization area of the turfgrass species increases recently, the demand for new and improved cultivars increases. Thus, substantial progress has been made in applying modern biotechnology to develop genetically engineered (i.e., biotech) creeping bentgrass with new traits that eluded the breeders. This review article addresses the advances made in developing biotech creeping bentgrass, which are categorized in the following topics: (i) genetic transformation of creeping bentgrass, (ii) development of various biotech creeping bentgrasses by genetic engineering, and (iii) progresses in the deregulation of herbicideresistant creeping bentgrass.

Problem Based Learning (PBL) is one of methods which has been developed to promote student-centered learning and to pursue self-directed learning for life-long learning. The purpose of this study is exploring the possibility of Problem Based Learning (PBL) in college Earth science course. The participants of this study were fourteen students attending an Earth science class at Sookmyung Women's University in Seoul. PBL was implemented in the form of group project with utilizing Web-based course tool. We provided questionnaires and conducted interviews to figure out students' perception about PBL. The findings were as follows: Through a given experiences, (1) students participated more actively than LBL (Lecture Based Learning), (2) more students were engaged with self-directed learning, and (3) students made higher cognitive efforts. LBL seemed to be more efficient way to acquire factual knowledge. In the meanwhile, PBL did not seem to affect the improvement of communication skills. Students could not make use of Web-based course tool effectively in communicating with other team members. In this study, we found that college student participants preferred problems related to everyday life, environmental issues and interesting but unusual incidents. On the other hand, they felt difficult in open-ended problems, especially when they were asked to provide their own evaluation. On the basis of PBL experiment in this paper, we present one method of successful implementation of PBL and suggest topics which should be studied in the future.

This study is based on the assertion that science museums should consider visitors' views and expectations as they are not satisfied in many cases. In this study, we investigated 31 scientifically gifted students and 177 science high school students about their image of science museums. Using the questionnaire, it was found that only 51% of students visited science museums; however, the average number of visits was 4.2. This means that students tended to re-visit after the first visit of the science museum. Students had a 'good' image of science museums when they incurred hands-on experiences and observed new, interesting, curious and funny exhibits. And students had a 'bad' image of science museums due to the following aspects: lack of new and interesting exhibits, information and guide, diverse contents, and hands-on experience; deficiencies in environment; and inadequacy of the management, operation and composition of exhibits. Therefore, they hoped that science museums will provide more hands-on experiences and experiments, new and interesting exhibits, systematic management and composition of exhibits, information and guides, and a good environment. So science museums need to pay special attention to aspects like management, information guides and environment for the first-time visitors. Based on the above results, we suggested "Directions for a good science museum based on students' views". While asking students what topics they wanted to know and learn in a science museum, each student was given the choice of four topics; eventually, 2.9 answers overlapped for each topic. When classifying students' topics into four main themes for the Gwangju National Science Museum, the order from the most popular theme to the least one was 'science in everyday life', 'ocean/space/future science', 'light and science', and 'culture, art and science'. Among the topics mentioned by students, only 37% are exhibited in Seoul, Gwacheon, Daejeon, or Gwangju science museums. We hope that the results and research methods will be used for evaluation, re-construction, and reinvigorated presentation of science museums.

In order to make a connection in teaching similar concepts between mathematics and science in teaching similar concepts, this paper analyzed the contents related to capacity, volume, weight, and mass in the mathematics and science textbooks aligned with the national elementary curriculum. We first explored when to present such topics in both textbooks, and then analyzed in what ways the topics were addressed in terms of quantitative comparison, vocabulary, units of measurement, measurement, tools for measurement, estimation, and connections to real life. The results of this study showed that there were some aspects emphasized in common both in mathematics and science textbooks. The analysis of this study also demonstrated subtle but considerable differences according to the characteristics of two subject matters. Based on these results, this paper provides implications for elementary school teachers to consider in teaching capacity, volume, weight, and mass through mathematics and science lessons.

Purpose: The purpose of this study was to identify the knowledge structure of cancer survivors. Methods: For data, 1099 articles were collected, with 365 keywords as a Noun phrase extracted from the articles and standardized for analyzing. Co-occurrence matrix were generated via a cosine similarity measure, and then the network analysis and visualization using PFNet and NodeXL were applied to visualize intellectual interchanges among keywords. Results: According to the result of the content analysis and the cluster analysis of author keywords from cancer survivors articles, keywords such as 'quality of life', 'breast neoplasms', 'cancer survivors', 'neoplasms', 'exercise' had a high degree centrality. The 9 most important research topics concerning cancer survivors were 'cancer-related symptoms and nursing', 'cancer treatment-related issues', 'late effects', 'psychosocial issues', 'healthy living managements', 'social supports', 'palliative cares', 'research methodology', and 'research participants'. Conclusion: Through this study, the knowledge structure of cancer survivors was identified. The 9 topics identified in this study can provide useful research direction for the development of nursing in cancer survivor research areas. The Network analysis used in this study will be useful for identifying the knowledge structure and identifying general views and current cancer survivor research trends.

The goal of this research is to analyze the trend of Korean fourth grade students' achievement in TIMSS 2011 and TIMSS 2015 science content domains and to suggest implications for science curriculum and teaching & learning improvement. With four elementary science teachers and three science educators, we analyzed Korean fourth grade students' percentage of correct responses in TIMSS 2015 science content and cognitive domains, and conducted item-curriculum matching analysis for test items. According to the results, Korean students performed relatively better in test topics covered in the science curriculum for 3-4 grades regardless of the science content domain (i.e., Life science, Physical science, or Earth science). Korean students showed low percentage of correct answers for items related to such topics as heat conduction, the action of electricity, the motion of the earth and the moon, etc., which were covered in the 5th-6th grades in the 2009 revised curriculum. For science cognitive domains, Korean students' achievement dropped significantly in reasoning between TIMSS 2011 and TIMSS 2015. Discussed in the conclusion are implications to reconstruct elementary school science curriculum, and ways to improve science teaching and learning.

Human Ecology researches studying human life patterns in Korea are on the same tracts of recent global promotion in Korea as that of other academic studies. In this changing academic atmosphere, Human Ecology-based researches are in demands of suitable research topics and methods. This study was done to investigate the present research situations of Human Ecology-based subdivisional fields, including food and nutrition, clothing and textiles, child studies, family studies, home management, housing studies, consumer sciences and home economics education, by an increasing need in the society of KHEA (Korean Home Economics Association). The study focused on understanding the trends of research topics and methods shown in the papers published in major academic periodicals in Korea as well as world-class (SCI, SSCI) journals in order to predict the future for Ecology-based studies in Korea. The data were collected from all periodicals from January, 2000 to August, 2003, listed in the Korean Research Foundation and from world-class journals comparable to the former. Twenty-six periodicals were chosen for analysis, including papers with authors of ecology-based, field faculty at colleges or universities. There were some differences between the Korean and world-class research topics and methods. In order to narrow the gap between the two, we suggested that serious consideration be given to the research's application-ability toward human beings, which would be the home-ecology study's identity. The same criteria in these fields as used in other natural science fields are not suitable for supporting and evaluating research proposals and outputs, and recent global academic promotions may not be desirable in some respects. However, they do present an opportunity to expose Korean researcher's to world-class scientific societies and upgrade their studies. These efforts should stimulate the field of Human-Ecology studies and enhance the recognitions of these fields among future students.

Purpose: This study aimed to identify and compare hospice care research topics between Korean and international nursing studies using text network analysis. Methods: The study was conducted in four steps: 1) collecting abstracts of relevant journal articles, 2) extracting and cleaning keywords (semantic morphemes) from the abstracts, 3) developing co-occurrence matrices and text-networks of keywords, and 4) analyzing network-related measures including degree centrality, closeness centrality, betweenness centrality, and clustering using the NetMiner program. Abstracts from 347 Korean and 1,926 international studies for the period of 1998-2016 were analyzed. Results: Between Korean and international studies, six of the most important core keywords-"hospice," "patient," "death," "RNs," "care," and "family"-were common, whereas "cancer" from Korean studies and "palliative care" from international studies ranked more highly. Keywords such as "attitude," "spirituality," "life," "effect," and "meaning" for Korean studies and "communication," "treatment," "USA," and "doctor" for international studies uniquely emerged as core keywords in recent studies (2011~2016). Five subtopic groups each were identified from Korean and international studies. Two common subtopics were "hospice palliative care and volunteers" and "cancer patients." Conclusion: For a better quality of hospice care in Korea, it is recommended that nursing researchers focus on study topics of patients with non-cancer disease, children and family, communication, and pain and symptom management.

This study explored the change in keywords and topics in newspaper articles related to schizophrenia after the Gangnam murder case. The study examined newspaper articles related to schizophrenia for five years before and after the Gangnam murder case. A semantic network analysis was conducted using the NetMiner 4.4.1 program. 610 articles between 2013 and 2018 were retrieved from 8 national newsletters. The most frequent core keyword was 'treatment' before the murder case, but 'incidents' after the case. Four topics were identified: 'becoming chronic if missing the time of treatment due to prejudice', 'being curable with early treatment', 'living an ordinary life with medication', 'being indicted as a murderer while impaired by a mental disorder' before the murder case. After the case, four topics were identified: 'committing murder for delusions, not misogyny', 'medication non-adherence leads to more impulsive behavior', 'claiming leniency for criminals due to the mental impairment', 'killing the police who were mobilized to stop stabbing rampage'. These findings suggest that newspaper articles should provide accurate information about schizophrenia to reduce prejudice and stigma toward patients with schizophrenia and other forms of mental illness.
