The application of modern ecological, ultrastructural and molecular methods, aided by the cultivation of numerous cyanobacterial morphotypes, has substantially changed our knowledge of these organisms. It has led to major advances in cyanobacterial taxonomy and criteria for their phylogenetic classification. Molecular data provide basic criteria for cyanobacterial taxonomy; however, a correct phylogenetic system cannot be constructed without combining genetic data with knowledge from the previous 150 years research of cyanobacterial diversity. Thus, studies of morphological variation in nature, and modern morphological, ultrastructural, ecophysiological and biochemical characters need to be combined in a “polyphasic” approach. Taxonomic concepts for generic and infrageneric ranks are re-evaluated in light of combined phenotypic and molecular criteria. Despite their usefulness in experimental studies, the limitations of using strains from culture collections for systematic and nomenclatural purposes is highlighted. The need for a continual revision of strain identification and proper nomenclatural practice associated with either the bacteriological or botanical codes is emphasized. Recent advances in taxonomy are highlighted in the context of prospects for understanding cyanobacterial diversity from natural habitats, and the evolutionary and adaptational processes that cyanobacteria undergo.

This study aimed to building models to understand the relationships between reasoning resources and content knowledge. We applied Support Vector Machine and linear models to the data including fifth graders' scores in the Cornel Critical Thinking Test and the Iowa Assessments, demographic information, and learning science approach (a student-centered approach to learning called the Science Writing Heuristic [SWH] or traditional). The SWH model showing the relationships between critical thinking domains and academic achievement at grade 5 was developed, and its validity was tested across different learning environments. We also evaluated the stability of the model by applying the SWH models to the data of the grade levels. The findings can help mathematics educators understand how critical thinking and achievement relate to each other. Furthermore, the findings suggested that reasoning in mathematics classrooms can promote performance on standardized tests.

In the 4th Industrial Revolution and changes in the construction industry market, the importance of information management is becoming more emphasized. For efficient use of information, construction data must be collected, processed and analyzed more quickly and accurately, depending on the purpose of the project. Thus, data could be utilized as integrated knowledge. However, there is a limit to searching or managing construction information produced in various formats over the entire life cycle by index words. Therefore, this study proposes a construction information integrated management plan that reflects the characteristics of the construction industry by applying the OWL concept. For this, as an initial study, an architectural object of small size and clear features was needed. Therefore, a construction information management study using OWL was conducted for Korean traditional architectural style houses (Hanok) which has these characteristics.

This study was performed to offer basic data base on traditional Korean festival foods for a traditional Korean food data integration system, that is based on literature reviews. The Korean lunar calendar has seasonal divisions reflecting traditional Korean holidays. In the past, there were many customs corresponding to emotions, and foods were in accordance with customs, festivals, and seasons. Today, we are well aware of the traditional Korean foods of New Year's Day(Seollal), the Korean Harvest Festival(Chuseok), the First Full Moon Day(Jeongwol Daeboreum), the Winter Solstice(Dongji), and the hottest summer day(Sambok). However, many other traditional Korean holidays are disappearing from the modem Korean life-style. This study made the following classifications for traditional Korean festivals. Seollal(Seol), Ipchun, and Jeongwol Daeboreum in January; Junghwajeol in February; Samjinnal in March; Hansik and Chopail in April; Dano in May; Yudu and Sambok in June; Chilseok and Baekjung in July; Chuseok in August; Jungyangjeol in September; Siwolmuoil in October; Dongji in November; and Napil and Seotdal Geumeum in December. The familiar traditional Korean festival foods are as follows: Seollal's festival foods consist of 5 main dishes, 35 side dishes, 12 kinds of tteok lyou, 21 kinds of hangwa lyou, 2 kinds of emchong lyou, and 3 kinds classified as others; this includes tteokguk, manduguk, galbijjim, sinseollo, jeon, pyunyuk, kimch, tteok, sikhe, sujunggwa, fruits, and seju on Seollal. The festival foods for Jeongwol Daeboreum consist of 3 main dishes, 27 side dishes, 5 kinds of tteok lyou, 3 kinds of hangwa lyou, 4 kinds of emchung lyou, and 3 kinds classified as others; this includes ogokbap, mugeunnamul, yaksik, yumilkwa, wonsobyung, guibalgisul, and burum on Jeongwol Daeboreum. The festival foods for Sambok consist of 6 main dishes, 18 side dishes, 4 kinds of tteok lyou, 3 kinds of eumchung lyou, and 2 kinds classified as others; this includes yukgaejang, imjasutang, youngyejjim, tteoksudan, santtalgihwaschae, and subak on Sambok. Chuseok's festival foods consist of 4 main dishes, 22 side dishes, 18 kinds of tteok lyou, 6 kinds of hangwa lyou, 4 kinds of eumchung lyou, and 3 kinds classified as others; this includes oryeosongpyeon, toranatang, garijjim, dakjjim, namuls, tteok lyou, baehwachae, and fruits on Chuseok. The festival foods for Dongji consist of 6 main dishes, 6 side dishes, 7 kinds of tteok lyou, 1 kind of hangwa lyou, 2 kinds of eumchung lyou, and 1 kind classified as others; this includes patjug, jeonyak, and dongchimi on Dongji. Based on these data, it is recommended that knowledge of traditional Korean festival foods be handed down, preserving and develop their excellence and to further scientific studys.

This study was conducted to investigate the nutritional knowledge and eating behavior of elementary school senior students in Incheon area and to develope education program appropriate for them. Questionnaire was developed and distributed to 551 fifth and sixth grade students of fourteen elementary schools in Incheon area. The data was analyzed using ANOVA. According to the results on nutritional knowledge and attitude, senior students were aware of major sources of some nutrients, but didn't seemed to know about the role of some nutrients. Nevertheless, it was favorable that they took various food from major food groups. But the proportion of students skipping breakfast and taking instant food was high. Their table etiquette was not good at home, but attitude for food hygiene was comparatively good. They recognized Korean traditional food more nutritious than fast food. Even though they understood what was right for eating behavior, they didn't practice it correctly. From these results, it seemed that follow-up study or intervention is necessary to improve nutritional knowledge and eating behavior of the students. Qualified teachers, nutrition specialists, are required in order to develop and apply systematic nutrition education program for correcting inappropriate eating behavior of the students. Furthermore, nutrition education for their parents will be more effective.

The purpose of this study was to identify the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, critical thinking, and problem solving ability in nursing students. The study was conducted with a nonequivalent control group pre-posttest design. Seventy four participants were assigned to either the experimental group(34) or control group(40). The simulation-based cardio-pulmonary emergency care education included lecture, team-based practice, and debriefing, and it was implemented with the experimental group for a week from September 1 to December 11, 2015. Data were analyzed using chi-square, t-test and ANCOVA by using SPSS 21.0 program. The experimental group who had the simulation-based education showed significantly higher knowledge(F=24.930, p<.001), and critical thinking(F=5.951, p<.05) for cardio-pulmonary emergency care compared with the control group who had traditional education. However, there were no significant differences in problem solving ability(F=3.327, p>.072). The results indicate that a simulation-based education is an effective teaching method to improve knowledge and critical thinking in nursing students learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team positive education program of nursing students.

Purpose: This study was done to examine the level of use of essential oriental nursing terms and related characteristics among nurses in oriental medicine (OM) hospitals. Method: A cross-sectional survey design with convenience sampling was employed. Questionnaires were used to collect data from 315 nurses in seven university-affiliated OM hospitals. The questionnaire included 174 oriental nursing terms about actions, tests, drugs, and theories. Multiple regression analysis was performed to determine factors associated with the level of use. Results: The response rate was 98.1% (n=309). Overall mean score for use of essential oriental nursing terms was 2.7(${\pm}\;0.7$) on a five-point Likert scale. Significant factors associated with the level of use were workplace and knowledge of oriental nursing theory terms. Nurses who worked in nursing care wards and those who had a higher level of knowledge of oriental nursing theories had a higher level of use. Conclusions: These findings indicate that level of use of essential oriental nursing terms were below average. Educational programs to enhance knowledge of oriental nursing theories need to be implemented for nurses in OM hospitals, considering their workplace, in order to facilitate nursing data sharing and communication among healthcare providers.
