The purpose of this study is to present the development direction of future reading education by examining the characteristics of reading materials within the high school textbook developed as the 2015 revised curriculum. For this purpose, reading materials of high school textbooks were analyzed in Korean language, mathematics, English, integrated science, and integrated social studies. The analysis criteria of reading materials were subject type, purpose, and student activities. As a result of the study, reading materials on various themes such as humanity, liberty, culture, environment, and district were presented in the integrated society and integrated science textbook of the 2015 revised curriculum. In particular, the Korean language curriculum was composed of a unit called "reading one book in one semester". However, most reading materials have no guidance on reading effective or reading direction, and lack of reading materials and information for extended reading. The reader's reading of the textbook was found to be simply supplementing the learning content of each unit or presenting fragmentary cues for conceptual purposes. This suggests that there is a lack of awareness of students' interest in reading, internalization of reading, and extension of reading. In this paper, we suggest supplementary materials of reading materials for expanding the high school textbooks, and explore the developmental relationship between textbooks and reading education through suggestions on aspects of textbook composition and teaching methods.

The purpose of this article is to problematize the existence of a possible Ibero-American informational thinking. It was initially observed that a relative absence of Ibero-America in the international presentations and mappings of information science exists. Below, the reality of the 22 countries that compose Ibero-America is discussed, a region that can be understood from a sociocultural and geopolitical perspective. Then, a mapping of the information science research in these countries is made. The main research topics found are: epistemological studies, relationships with library science, information literacy, representation and organization, bibliometric studies, information management, user studies, technological dimensions, and relationships with archival science and museum studies. Finally, a general epistemological configuration of information science is presented at a global level, highlighting the great trends of study of information that marked the decades of the 1960s and 1970s (physical model), 1980s and 1990s (cognitive model), and the 21st century (sociocultural model), and which manifested themselves in the different subareas that make up the field. The most recent research in information science, in addition to addressing information transfer (physical dimension) and its relationship with data and knowledge (cognitive dimension), has also incorporated aspects related to the social effects of information, its role in the constitution of identities and culture, and the importance of its material conformations. Such expansion reflects attempts to address the complexity of informational phenomena. Therefore, it is concluded that it is important to place the specific contributions of Ibero-America in this context.

ISSR PCR technique was applied to investigate genetic relationship among 5 Mountain cultivated ginseng populations (Jinan, Hongcheon, Punggi, Andong and Yeongju) and cDNA libraries of wild ginseng roots were constructed and analyzed functional genes related to morphogenesis via EST. Twenty four ISSR markers tested produced 127 polymorphic loci from 5 regional Mountain cultivated ginseng. Among the regional samples, Yeongju was made 18 polymorphic loci that were the highest level of variations among the cultivated regions. The range of similarity coefficient was 0.46~0.58 and the regional samples of Punggi and Hongcheon, Jinan and Andong were classified to similar groups respectively, whereas Yeongju was shown to be separate group with high level of genetic variation in UPGMA cluster analysis. As a result, there was no relationship according to geographical distance and genetic similarity. Eleven cDNA clones were consisted of 9 known genes and 2 unknown genes analyzed by BLAST program of NCBI. To recognize expression pattern of Homeodomain transcription factor related genes, Northern Blot analysis was performed for wild ginseng's leaf and root. As a result, the gene was only expressed by Mountain wild ginseng root.

Objectives: This study was performed to review the research trends in the relationship between primary dysmenorrhea and doppler indicies of uterine artery. Methods: The search for related papers used 'Pubmed', a reserch engine in the America National Library of Medicine and Korean studies Information Service System (KISS). Used searching terms were 'primary dysmenorrhea', 'menstrual pain' in all cases. And among these studies, we searched by using key word 'uterine artery', 'doppler indices', 'doppler parameters', 'pulsatile index', 'resistance index'. Results: Overall 49 studies, 8 studies were finally selected to this study. There were 6 controlled studies and 2 randomised-controlled studies. In all 8 studies, transvaginal ultrasound was used to measure the resistance of uterine blood vessels. All of these studies reported that in patients with primary dysmenorrhea, hemodynamic values of uterine arteries measured by Doppler ultrasound were significantly higher than in normal subjects. Conclusions: According to the results, it was found that there was a positive correlation between the pain level of primary dysmenorrhea and the pulsation index and resistance index of the uterine artery. Based on these results, it can be seen that the doppler indicies of uterine artery have the potential to be used as an evaluation scale for Korean traditional medicine for primary dysmenorrhea.

Persimmon (Diospyros kaki Thunb) fruit is one of the most important fruit and have been cultivated from ancient times in Korea. In this study, we found 16 EST-SSR markers that contained one or more EST-SSR sites from 246 cDNA sequences. The developing of EST-SSR marker analysis from 42 persimmon cultivars was compared by genetic relationships and morphological relationships using 6 qualitative traits (fruit related 6 traits) and 19 quantitative traits (flower related 19 traits). In this study, 25 primer sets were tested to identify PCR polymorphism and 14 potential EST-SSR primer pairs were selected. The result of morphological relationship EST-SSR marker analysis showed that the coefficient 0.02 was difficult to categorize in several groups. And then, coefficient 0.77 of genetic relationship showed that the group was classified as four groups. The result of correlation distance between genetic relationship and morphological relationship were investigated was low significance (-0.03). Our results also provided an optimized method for improvement of breeding efficiency and introduce of superior character at persimmon cultivars using EST-SSR markers which was useful for further investigation.

The effect of Helicobacter pylori (H. pylori) eradication on the development of metachronous recurrence after endoscopic resection (ER) of gastric adenoma is not well defined. The aim of this study was to assess the efficacy of H. pylori eradication after ER of gastric adenoma for the prevention of metachronous recurrence. A systematic literature review and meta-analysis were conducted using the databases Ovid-MEDLINE, EMBASE, Cochrane Library, KoreaMed, and KMBASE. Thus, a systematic review and meta-analysis was performed to investigate this relationship. Pooled risk ratio for metachronous gastric lesions with regard to H. pylori eradication was calculated, and heterogeneity was also measured. Five eligible studies were finally identified in systematic review, and included in meta-analysis. H. pylori eradication was associated with overall 55% lower odds of metachronous events (RR=0.55; 95 % CI 0.34-0.92). Based on the best available evidence, eradication of H. pylori can also provide protection against metachronous recurrence after ER of gastric adenoma.

The purpose of this systematic review was to investigate the association between periodontal disease and chronic kidney disease. A search of Embase, PubMed and The Cochrane Library databases was performed up to April 17, 2016. Article selection was based on cohort study design and the study subjects were patients with periodontal disease or severe periodontal disease. The final result was development of chronic kidney disease and kidney function decrease based on the estimated glomerular filtration rate values. The quantitative synthesis of the final selected articles was assessed using Review Manager statistical analysis software. A fixed-effects model meta-analysis was performed to estimate the degree of association between periodontal disease and chronic kidney disease. The search strategy identified 3,018 potentially eligible articles, of these, four studies were finally selected for meta-analysis, revealing that periodontal disease was significantly associated with the risk of developing chronic kidney disease (odds ratio, 1.65; 95% confidence interval, 1.44~1.90; p<0.001). In order to prevent the development of chronic kidney disease and kidney function decrease it is important to prevent periodontal disease, as well as minimizing the traditional risk factors known to reduce the quality of life of patients and increase disease burden.

This study performed meta-analysis of published articles to examine the relationship between sarcopenia and smoking. We searched the PubMed, EMBASE, Cochrane library, and RISS database sup to January 2017 using search terms such as sarcopenia AND (smoking OR tobacco OR cigarette). A total of 25 articles were included in the analysis (seven cohort studies and 18 cross-sectional studies). Incidence of sarcopenia in smokers and non-smokers was analyzed by the random effects model. Incidence of sarcopenia was OR 1.49 (95% CI 1.21, 1.84, p<.001, I2 = 88.20%), Asian (OR 1.28, 95% CI 0.91, 1.78, p=0.150, I2=85.32%), and Western (OR 1.65, 95% CI 1.25, 2.17, p<.001, I2=91.08%), Western smokers showed a significantly higher incidence of sarcopenia:males and females with OR 1.25(95% CI 1.11, 1.40, p<.001, 12=87.4%) and 1.80(95% CI 0.98, 3.30, p=.057, 12=89.1 %) respectively. Male smokers showed significantly higher incidence of sarcopenia. Based on the results of the study, smoking in Western males is related to sarcopenia. However, since the criteria for the diagnosis of sarcopenia and the criteria for smoking were different, cumulative individual clinical studies applying uniform assessment for the evaluation of sarcopenia and smoking status are needed in the future.

This study analyzed the usage characteristics and requirements of students who are users of the middle school education space, and the following results were obtained: First, we could see that various types of classes were needed, such as lecture-style classes, team projects, and four-person consultation and discussion classes, in a way that helped to improve the desirable teaching patterns and learning ability. Second, the place where space was used during the break and the relationship between peers, revealed that most of them were in the classroom and the hallway, and the peer group was composed of three to eight people or more, that were active with various compositions. Third, a gym, library, toilet, stairway, cafeteria, nurse's office, and teachers' room appeared in the center of the building, indicating the need for a balanced layout. Fourth, physical education (dance) rooms, audiovisual rooms (performance rooms), workshops (personal creation), snack bar, rest area, spacious indoor square, and study rooms were needed as facilities that can help learning activities other than current facilities. These outcomes show that the existing classroom layout and space composition formats require some spatial restructuring.

The current notion of digital divide is quite different from the traditional definition of digital divide. People have considered that digital divide and social capital are separated notions and are not related with each other. However, in this current information society, the digital divide affects the process of building social capital, and thus these two concepts have become closely related with each other. Now, the notion of digital divide is combined with social capital theory and has created new social phenomena that multiple divisions of social structure. Information and Communication Technologies(ICT) plays important roles in this new social and informational environment. This research identifies the relationships between digital divide caused by ICTs and social capital. To investigate the relationship between digital divide and social capital, this research used datasets provided by the Pew Internet & American Life Project (March 2002 survey).
