The purpose of this study is to investigate the trends of character-related research in science education by analyzing science education research literatures in South Korea. To this end, literatures on character were extracted from the KCI-listed journals and theses from 1990 to December 2016, and analyzed according to the criteria such as terms relating to character, year of publication, research design and method, and research content. A total of 54 KCI-listed papers and 67 theses were extracted. As a result, 46%, 49%, and 5% of the researches include the terms like character, ethic, and moral in their titles. According to the year of publication, it was found that the number of research papers related to character increased rapidly by more than two times in 2012 as compared to the past years. According to research objects, researches about gifted students were the most common, and when considering the ratio of gifted students to general students, many studies related to character concentrated on gifted students. Starting 2009, research papers on qualitative and hybrid research design begin to advance as compared the number of papers in quantitative research design. With regards to research methods used, seven methods were classified; five of them ranged from 16% to 19% while interpretive research method was 12% and test tool validity study was the lowest at 2%. By extracting 30 representative keywords so as to analyze the contents of character-related researches, we found various implications to character in relation to nature and researches about SSI, etc. As time passed by, the contents of character-related research in science education became more diversified and the number of researches increased. New research contents appeared due to the needs of the times.

Background: Nebulized colistimethate is increasingly used, because there are problems such as renal dysfunction and low distribution within the lungs when colistimethate is administered intravenously. This study was designed to compare and analyze the changes in renal function by of nebulized colistimethate treatment for its safe administration. Methods: This study retrospectively reviewed the electronic medical records of adult patients above 19 years old, receiving only the nebulized colistimethate at least 4 days in Yonsei university health system from Nov 2014 to Aug 2015. Acute kidney injury (AKI) was determined by using the RIFLE criteria (Risk, Injury, Failure, Loss and End-stage renal disease) according to serum creatinine (SCr) levels before and after use of nebulized colistimethate. Results: 48 patients were included our study and their SCr increased significantly after nebulized colistimethate treatment ($SCr_0$ vs. $SCr_1$; $0.85{\pm}0.80$ vs. $1.00{\pm}0.82mg/dL$, n=48, p<0.001), but the changes were in normal range according to the standards at Yonsei university health $system^a$. Among 48 patients, 38 patients were in the non-AKI group (79.2%), and 10 patients developed AKI (20.8%). Within the AKI group, 2 patients were in the Injury group (20%) and the other 8 in the Risk group (80%). Conclusion: There was no significant difference in age, dosage and duration of treatment between AKI group and non-AKI group (p>0.05). The study has a significance in that it reviewed the safety of nebulized colistimethate only treatment to national patients, analyzing its nephrotoxicity. It has confirmed that nebulized colistimethate is a safer method than intravenous injection, and requires to establish a guideline for the use of nebulized colistimethate in further studies with broader patient groups. $^a$ : SCr Male 0.68-1.19 mg/dL, Female 0.49-0.91 mg/dL.

The purpose of this study is to explore the main characteristics regarding of implicating competence-based curriculum in Finland's home economics curriculum by analyzing curriculum documents and related literature. The research findings are categorized into four main characteristics. First, home economics in Finland belongs to the 7-9 grades. The key content areas are composed of 'food knowledge & skills and food culture', 'housing & living together' and 'consumer & financial skills' at an integrated approach. Secondly, the subject competences of home economics are not presented; however, the general objectives of transversal competences are defined in Finland's curriculum document. Transversal competences describe the aspects of the objectives that are emphasized in grades 7-9 and strengthens the connectivity with each subject. Thirdly, the objectives of home economics included in the instructions in Finland consist of a content system that links learning skills, content areas, and transversal competences. Both learning skills as a role of subject competences and content areas as objectives support teachers who restructure an curriculum. Fourth, in terms of achieving subject objectives, the assessment criteria in Finland home economics is to evaluate the achievement of good knowledge and skills through actual performance. Based on the research findings, the main features of the revised curriculum in Finland include encouragement of flexibility in education systems and learner's uniqueness in schools. If the implementation of subject competences in home economics is to be strengthened, it is necessary to intergrate the knowledge and competence, require a curriculum system for implements' subject competence, carryout assessment as learning to learn, and facilitate school community and teacher community for deeper co-operation.

There are several factors to consider for a ship to enter or depart a port safely. It is particularly important to identify the tides in the port to reduce the risk of stranding the ship. Most previous studies have focused on finding and analyzing harmonic constants. However, the research on the analysis and accuracy of harmonic constants in other hydrographic agencies is lacking. In this study, six Korean ports (Incheon, Gunsan, Yeosu, Busan, Ulsan, and Sokcho) were compared to the British and Korean tide tables based on actual information. To find the cause of tidal difference, the tide height, tide time, and form factor were calculated using harmonic constants. The information was then compared with British and Korean data. As a result of the difference in analysis of actual information and tide tables, there was a difference between the actual tide height and time at each port. The cause was found to be the difference in the harmonic constant, tide, and form factor between the UK and Korea. Therefore, this study, the Korean standard port should be added to the British tide table, and harmonic constants, which are the criteria for creating tides, must be constantly updated with the latest information. Additionally, the tide tables produced in each country are more accurate than the tide tables produced in UK.
Brachytherapy is a treatment in which radioactive isotopes are placed inside the body to intensively irradiate the tumor with radiation. Because brachytherapy uses a radioisotope source with a high dose rate, it is very important to know the exact location and dose of the source. However, in clinical practice, it is evaluated inaccurately with the naked eye through rulers and autoradiographs. Therefore, in this study, a dosimeter that can be used for brachytherapy was developed using a lead(II) iodide (PbI2) material, and the applicability was evaluated by analyzing the reproducibility, linearity, and PID items. As a result of reproducibility evaluation, the RSD value was 1.41%, satisfying the evaluation criteria of 1.5%. As a result of the linearity evaluation, the R2 value was 0.9993, which satisfies the evaluation criterion of 0.9990. As a result of PID evaluation, it showed only a difference of 0.06 cm compared with the theoretical value of the inverse square law of distance at the 50% dose reduction point. The dosimeter manufactured in this experiment shows results that satisfy the standard in all evaluations, so it is judged that the possibility of applying the dosimeter in the radiation brachytherapy area is sufficient.

School violence has long been recognized as a social problem, and various efforts have been made to prevent it. In this study, we propose a system that can prevent school violence by analyzing data on the frequency of conversations between students, friendship and preference to be in the same group. This data was quantified using a Likert scale questionnaire, and also grouped into the appropriate number of clusters using the K-means algorithm. Additionally, the homeroom teacher observed the frequency and nature of conversations between students, and targeted specific individuals or groups for counseling and intervention, with the aim of reducing school violence. Data analysis revealed that the teachers' qualitative observations were consistent with the quantified data based on student questionnaires, and therefore applicable as quantitative data towards the identification and understanding of student relationships within the classroom. The study has potential limitations. The data used is subjective and based on peer evaluations which can be inconsistent as the students may use different criteria to evaluate one another. It is expected that this study will help homeroom teachers in their efforts to prevent school violence by understanding the relationships between students within the classroom.

The purpose of this research is to develop a Home Economics education curriculum that can promote citizenship through critical literacy. To this end, the 'housing' area in the 2015 revised curriculum of home economics and textbooks were analyzed from a critical literacy perspective. Using Laster(1986)'s critical science curriculum development course and "A Teacher's guideFamily, Food and Society"(Staaland & Storm, 1996), a 'Citizenship raising curriculum of home economics education in the housing area.' was developed. The results of this research are as follows. First, when the the curriculum was examined, the teaching objectives of the overall subject, or the achievement criteria, learning elements, and evluative methods of the housing area consisted of practical problem solving curriculum that can include critical literacy content. In addition, as a result of analyzing the text of the three textbooks' housing areas, it was found that most of them were described as adapting to and coping with the current culture, and few problems or social issues were mentioned that could lead to critical literacy. Second, the housing area curriculum for critical literacy learning was developed, with a total of 13 plan of 7 modules including continuous interests, valued ends, learning contents, and 26 learning materials including reading materials, and video materials. Based on the findings, the next curriculum and textbook should address social issues related to critical literacy and various classes of housing, and teachers' communities and training should be operated to support teachers who can be examplary for practical reasoning and critical thinking.
Pruritus (itching) is classically defined as an unpleasant cutaneous sensation that leads to scratching behavior. Although the scientific criteria of classification for pruritic diseases are not clear, it can be divided as acute or chronic by duration of symptoms. In this study, we investigated whether skin injury caused by chemical (contact hypersensitivity, CHS) or physical (skin-scratching stimulation, SSS) stimuli causes initial pruritus and analyzed gene expression profiles systemically to determine how changes in skin gene expression in the affected area are related to itching. In both CHS and SSS, we ranked the Gene Ontology Biological Process terms that are generally associated with changes. The factors associated with upregulation were keratinization, inflammatory response and neutrophil chemotaxis. The Kyoto Encyclopedia of Genes and Genomes pathway shows the difference of immune system, cell growth and death, signaling molecules and interactions, and signal transduction pathways. Il1a, Il1b and Il22 were upregulated in the CHS, and Tnf, Tnfrsf1b, Il1b, Il1r1 and Il6 were upregulated in the SSS. Trpc1 channel genes were observed in representative itching-related candidate genes. By comparing and analyzing RNA-sequencing data obtained from the skin tissue of each animal model in these characteristic stages, it is possible to find useful diagnostic markers for the treatment of itching, to diagnose itching causes and to apply customized treatment.

In this study, in order to grasp the current situation of indoor environmental pollution and indoor ventilation in one-room around the university in the post-corona era, we analyzed the experimental data and conducted a questionnaire survey on university students. By analyzing the content, the effects of formaldehyde, dust and other pollution on the human body, which are usually not easily detectable, are digitized and more easily taken into account. Among the experimental results, the concentration of VOC and HCHO, gas pollutants among indoor pollutants, exceeded the recommended criteria of the Ministry of Environment in most studio apartments. Overall, the average CO2 concentration was lower than the Ministry of Environment's maintenance standard (1000ppm), but it was relatively high in summer and winter, and it is believed to be caused by cooling and heating in an enclosed space. The levels of PM2.5 and PM10, particulate pollutants, increased in November and December, and it is believed that ventilation defects due to degradation in external temperature. There was no clear difference between the two types, and there was a very high correlation between PM2.5 and PM10, HCHO and VOC. It was found that temperature was closely correlated with all sources except CO2, and humidity was closely correlated with all sources except PM2.5 and PM10. Health risk assessment was conducted for formaldehyde. The average ECR of studio R2 in May was 3.91E-4, and the ECR figure in September was 3.65E-4, which was very high compared to other residential spaces. The R2 level was calculated as 4 people per 10,000 people in the lifetime risk of cancer of residents, exceeding the allowable risk. R8 also showed higher ECR results than other spaces after R2, especially in October, 2.01E-4, six times higher than R7 measured in October, and 1.87E-4 in July, four times higher than R9.
