This study is a descriptive research study to identify the relationship between cancer fatigue, quality of sleep, environmental sleep disturbance, and comfort perceived by hospitalized cancer patients. Data were collected with structured questionnaires from 113 cancer patients from a university hospital in J city, Gyengnam, from September 17 to November 5, 2019, and analyzed using SPSS 21.0, using independent t-test, one-way ANOVA, Scheffé test, Pearson's correlation coefficient, and stepwise multiple regression. The subjects' Comfort is significantly different depending on education level, Cancerous type, Radiation treatment status, Usual exercise status. The result showed that comfort was negatively correlated with cancer fatigue(r=-.609, p<.001), quality of sleep(r=-.478, p<.001), and environmental sleep disturbance(r=-.297, p=.001). The variables that had a significant effect on comfort were cancer fatigue(β=-.42, p<.001), subjective quality of sleep(β=-.30, p=.001), and cancer type(β=-.18, p<.015), and the explanatory power was 46.1%(F=27.24, p<.001). Based on these results, it is necessary to develop a program to improve the quality of sleep and to reduce the cancer fatigue by cooperating with medical and nursing staff in multidisciplinary ways to enhance the comfort of hospitalized cancer patients.

Officially given a historical signifier as Gwangju Democratic Movement since 1987, far-right and conservative group have restated that $5{\cdot}18$ is a rebellion and a riot that was committed by rebellious elements who obeyed North Korea's command or who were connected with North Korea. As those who had been responsible for the rebellion, revolt and riot were rewarded, far-right and conservatives' collective narrative that a country was born where the pro-North Korea left became dominated aroused extreme hostility towards $5{\cdot}18$. Far-right and conservatives involved in many different fields such as political party, university, press and media and civil group carry out incendiary discourse politics with intention to reestablish history and memory of $5{\cdot}18$ in their own story. Many people at online sites such as Ilbe Storehouse who are considered 'young right wing' is a main route to spread the far-right groups' remarks on $5{\cdot}18$. Ilbe is a main channel to reconstitute and reproduce the far-right conservatives' remarks and information on $5{\cdot}18$. Ilbe is one of main area where remarks of disparagement and ridicule, hostility and hatred on $5{\cdot}18$ unfurl. This study collects $5{\cdot}18$-related remarks and stories unfolded at Ilbe and examines how these remarks and stories make significance as to $5{\cdot}18$ and how information resources which remarks are dependent upon are connected each other. In this process, this study intends to find implications of incendiary politics that echoed of remarks on $5{\cdot}18$ have which at the online site Ilbe and by the far-right conservatives.

Sometimes inhabitants in remote areas have inadequate or no access to modern medicines or medical services. They can get benefit in term of the treatment against malaria by cultivating selected breeding of A. annua and making teas or decoctions from the plant materials following the proper way of tea preparation. In order to have the maximum extraction efficiency for artemisinin, different ways of tea preparations of A. annua were investigated by applying the developed DPP method and described in this article. Tea was prepared by three different ways (cooking, without cooking with/without shaking and microwave oven) with different times. From the results, it has been found that higher concentration of artemisinin (84.7%) can be attained by following the approach for tea preparation without cooking with shaking for 15 minutes (R.S.D. 2.34%). The concentration of artemisinin decreases with cooking more than 1.5 min in microwave oven. The utmost extraction (88.9% of artemisinin) is possible to extract by shaking with boiled 5% ethanol in distilled water (R.S.D. 2.28%).

In this case, we would like to discuss about the single rooted deciduous mandibular first molar. The deciduous mandibular molar of a five years old boy was shown to have a single root, bilaterally. Ordinarily, the maxilary molars have three roots and the mandibular molars have two roots. However, when the hertwig's epithelial root sheath do not invaginate properly during tooth development, root fusion can occur from the absence of root separation. Molars with fused roots not only have unfavorable crown to root ratio, but also according to many reports, have higher probability of having multiple congenitally missing teeth or dens invaginatus in the maxillary incisors, consequently requiring preventive dental treatment In addition, disorders such as ectodermal dysplasia, syndactyly, clinodactyly, bluish sclera can also be related to this condition. Root fusion is known to be of autosomal recessive inheritance. Up to date, single rooted molars have been reported several times in permanent dentitions but hardly in deciduous dentition, which is the motive for this paper.

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

This study was performed to analyze the secondary students' perceptions and self-efficacy of performance assessments in the science subject. The data was obtained from 236 middle school students and 222 high school students in seoul. The students had generally proper understanding about characteristics of performance assessment which include purposes of assessment and differences from other conventional achievement assessments. They responded that the performance assessments were not useful in their science learning and developing their potential abilities. They were not satisfied with reliability and validity of the performance assessments. The middle school students more positively responded than high school students regarding the reliability of the scoring system and the originality of the evaluating materials. The female students more positively thought than males about the reliability of assessment and the usefulness for learning science. The students' self-efficacy level of performance assessment were not low in comparison with another existing assessments. They had high level of self-efficacy in understanding of experimental procedures, and utilizing of experimental apparatuses, but had low level of self-efficacy in understanding purposes of experiments or issues of discussions, processing of experimental results, answering of problems in experimental discussions. The female students' self-efficacy of performance assessment were higher than male students'. There was statistically correlated with females' scores and their level of self-efficacy of performance assessment.

Despite the growing importance of socio-scientific issues (SSI), little work has focused on teachers' pedagogical knowledge, and few studies have examined how in-service teachers use and apply SSI-related instructional methods and strategies. Consequently, the purpose of this study was to explore how science teachers with lots of SSI teaching experience determined teaching orientation, selected and revised instructional methods, and devised assessments in science classroom. We used a case study approach aimed at a deep description of these teachers' teaching experiences and employed semi-structured and in-depth interviews with five experienced teachers. Our findings indicate that teaching orientation and learning objectives seemed to influence the selection and modification of instructional strategies and methods. In addition, students' learning experiences or classroom environment were considered and modified in light of achieving these learning objectives. However, introducing SSI into the classroom assessment is not seriously considered by most teachers. This study can provide teachers with useful information when designing and developing SSI classes, taking into account various aspects of the PCK such as learning orientation, instructional methods, learner expereince and curriculum standards.
