Recently, the number of cases of child abuse has been increasing and, consequently, the social interest in this issue is increasing. The purpose of this study is to examine the relationship between child abuse, rejection sensitivity and emotional regulation and to identify the mediating effects of rejection sensitivity in the relationship between child abuse and emotional regulation. For this purpose, a survey on child abuse, rejection sensitivity and emotional regulation was administered to 217 elementary school students in the fourth, fifth and sixth grades, who had been reported as victims of child abuse or managed as suspected child abuse victims in the Seoul, Gyeonggi, Gangwon, Chungcheong, and Gyeongsang regions. The data was analyzed using structural equation modelling and bootstrapping. The findings showed that child abuse was significantly negatively correlated with emotional regulation, but positively correlated with rejection sensitivity. Emotional regulation was significantly negatively correlated with rejection sensitivity. Second, the structural equation analysis also revealed that rejection sensitivity fully mediated the relationship between child abuse and emotional regulation. This means that child abuse has an indirect effect on emotional regulation through rejection sensitivity. Therefore, when counseling abused children with emotional regulation problems, it is important for the counselors to include interventions designed to lower their rejection sensitivity.

The purpose of this study was to identify the latent classes in the changing patterns of marital conflict perceived by mothers to explore its relationship with the changing patterns of mothers' depression, school readiness, self-esteem, and happiness of their children five years after their birth. A total of 1,243 responses from the 1st (2008) to 5th (2012) and 7th (2014) to 10th (2017) Korean Child and Youth Panel Study(KCYPS) were analyzed by Latent Growth Modeling (LGM) and Growth Mixture Analysis (GMA). The results were as follows. First, three changing patterns in the mothers' perceived marital conflict groups were identified: low-low changing, average-uptrend, and high-unchanging group. Second, an increasing pattern of depression was found from mothers of high-unchanging group over five years. Third, school readiness for their children was differentiated according to the latent classes. In particular, children from the low-low changing group showed higher readiness as well as self-esteem and happiness. Fourth, children from mothers of the low-low changing group showed high self-esteem and happiness in lower grades in elementary school. The results of this study suggest that the mothers' perceived marital conflict had an influence on themselves as well as their children's school related behaviors. Suggestions for an intervention program to resolve marital conflict are also discussed.

The purpose of this study is to investigate the level of awareness and current performance level of self-directed learning (SDL) in nursing students. The core concepts were defined and a rubric was developed through literature review. It was applied later to subjects and the results were analyzed. According to the results, there were significant differences between the current performance level and the awareness level of SDL in all items. Students who chose nursing as a major due to their high school/SAT grades showed lower current performance level than others. There were insignificant differences in the current performance level influencing the next grade. The level of awareness showed insignificant differences according to the reason for selecting nursing as a major, satisfaction on major, and grade point average (GPA). In conclusion, there was a discrepancy between the level of awareness and the current performance level of SDL of nursing students, which indicates that they were aware of the necessity of SDL, but did not actually perform it. Nursing educators should seek for strategies that can improve SDL ability of their students as well as to better grasp the level of the SDL of their student and the current performance level of SDL to apply them to the instructional design.
The major users of children's library are children and housewives. Recent increasing frequency of their visit to the library expands the function of it from the place where they borrow and read books further to the cultural space where each family unit can enjoy leisure activities. Though the children's library basically is a quiet place for reading books, peers' establishing friendship and emotional bond with the parents, and such plays as small scale muscular movements take place in addition to reading activities because the major users are infants under six or children in the lower grades in elementary school. Thus, in order to study the features and requirements that are inherent in the various behaviors of the children who use furniture, understanding of the particular factors in the physical environment of the children's library and the user context must precede. In reality, though the fixed form of the desks and chairs in the library was made by a small number of designers, a large number of children are using them in tremendously various ways beyond the ways that the designers had intended, adapting themselves to the environmental context. Therefore, the purpose of this study is to find out the children's using way of seats when they do reading and playing activities based on the way of interaction between children and parents, and, after modeling of the children's behavior data, to understand the demands inherent inside the various behaviors of children who use furniture.

Science teachers often suppose that students are able to know the symbolical meaning of graphs when they see the graphs. But such a assumption is not based on the firm theories but a mere image. And we need to search them for holding the abilities to construct and to interpret. In addition, unfortunately, many researchers show that they scarcely have the graphing skills. And then, The Test of Graphing in Science(TOGS) was administered to 535 7th to 12th graders, for we search them for holding the graphing abilities to some degree. Though the higher grade, the better score, they lack the first three among 9 objectives of TOGS which are scaling axes, assigning variables to the axes, using a best fit line, plotting points, translating a graph that displays the data, selecting the corresponding value for y(or x), interrelating/extrapolating graphs, describing the relationship between variables, interrelating the results of the two graphs. It was concluded from this that subjects' graph construction is lower than their graph interpretation in graph skills. It suggests that school science have a bias toward graph interpretation. This tendency represents more strikingly in the case of upper students in TOGS than the others'.
This study aims at analyzing physical and chemical properties of perlite substrate. Particles of substrate were divided into five categories In size: gravel, very-coarse, coarse, medium and fine grade. Particles of very-coarse and greater grades in perlite substrate occupied 98.5% of total particles. The air phase of total particles was distributed between 76.8% and 87.7% with especially showing that of very-coarse grade was lower than that of coarse or smaller one. However, the liquid and solid phases were vice versa. The cation exchange capacity (CEC) measured was highest in the fine grade. In drainage experiments, the water being drained from the substrate increased with the ratio of drain area, and the 65~70% of total water reduced within five minutes after irrigation. The drained volume was proportional to the depth of the substrate, which contained about 2mL.cm$^2$:by depth (cm). Due to quick reduction of the water in the substrate, the pF value increased in four minutes after irrigation and showed the highest negative correlation ($R^2$=0.997) with the moisture content of the substrate. The physical and chemical properties including drainage characteristics analyzed in this study can be, therefore, utilized to control the moisture content of perlite substrate, efficiently.

Background: Colorectal cancer (CRC) is one of the most common malignancies of the gastrointestinal tract. The aim of this study was to assess the general knowledge of CRC in individuals living in Rasht, Iran, using a population-based cross-sectional telephone survey. Materials and Methods: A total of 1557 participants between 18 and 80 years of age were interviewed using random sampling from the telephone directory. Knowledge of risk factors, symptoms, diagnosis, and prevention of CRC was assessed using a validated questionnaire. Results: The mean knowledge level of the 1,557 respondents (average age 46 y) was $13.5{\pm}4.29$ (maximum possible score = 26), and 46.4% (722/1,557) of the subjects achieved grades lower than the mean score. The mean scores for knowledge of symptoms and risk factors were $3.97{\pm}1.83$ (range: 0-7) and $5.17{\pm}1.65$ (range: 0-9), respectively. Older age, higher education, and employment were significantly associated with better scores for recognition of risk factors and warning symptoms. The majority of subjects correctly identified weight loss (70.2%; 1,093/1,557) and rectal bleeding (63.3%; 986/1,557) as symptoms of CRC, and that smoking (85.9%; 1,337/1,557) and a low-fiber diet (73.4%; 1,143/1,557) were risk factors. Approximately half of the subjects noted increasing age, genetic background and fried food as other risk factors. A considerable number (54.8%; 853/1,557) identified colonoscopy as a screening method for detecting CRC in asymptomatic patients. However, a third of the subjects in the target group for screening (${\geq}50y$) were not interested in undergoing screening, primarily due to a lack of symptoms. Conclusions: Our results suggest that the knowledge of CRC is poor among the public, and therefore greater attempts should be made to increase awareness. Public education emphasizing the risk factors and symptoms of CRC, as well as the importance of regular screening regardless of the presence of symptoms, may help to reduce CRC morbidity and mortality.

The purpose of this study is to measure and analyze primary causes of indoor air pollution, including carbon dioxide, minute dust, and total volatile organic compounds, for each room before the beginning of a class through the time of discharge after the end of the class in general classrooms, computer rooms, and science rooms of three newly-established schools that opened in 2006, examine properties of indoor air environment in each room by educational activities at school, and determine effective management schemes; the results of this study can be summarized as follows: 1) As for implications for each item found in the mean for each place, since minute dust (PM10) was more likely to occur in time slots full of students' activities, such as a traveling class and a recess, than in the middle of a class and could be expected fully, it is necessary to make a scheme for cleaning in order to reduce minute dust within a room, for example, by usually using a vacuum cleaner indoors. 2) While carbon dioxide was expected to vary with the differences in the amount of breath between higher-graders and lower-graders in a general classroom but showed insignificant difference by grades, showing differences in pollution by four times at a maximum according to the opening of a window as expected, it is necessary to implement artificial or natural ventilation and take a positive measure, for example, by presenting a concrete ventilation scheme, in order to improve indoor air pollution at a room practice. 3) Total volatile organic compounds were found to exceed the standard by more than twice in general classrooms, science rooms, and computer rooms of the schools because of building materials, furnitures including desks and chairs, panels and boards for environment beautification, and items which could be detected even from students' clothes; while a field directly-reading tool was used, obtaining high reliability for the results, it is necessary to apply an analytical method based on process test separately for actual correct measurement if a significantly great amount of total volatile organic compounds appear as compared with other schools due to measuring expenses and consecutive measurements. 4) Since formaldehyde (HCHO) was generally found to exceed the standard in general classrooms, science rooms, and computer rooms, it is necessary to establish and operate a ventilator during a class in a computer room which requires airtightness and a science room in which an organic compound should be used for a class.

In this research, we measured the number of lanes, distance, disposition of apartment that are affecting the road traffic noise to evaluate the current condition of G city's road traffic noise. We decide on a basis regarding an apartment price formation factor, and the apartment current price and the results that compared. To have a point scale, we set the maximum road traffic noise at a 8 lane road for 5 points, give 4 points for a 6 lane road, which has a $2.1{\sim}2.5\;dB(A)$ difference compared to a 8 lane road, give 3 points for a 4 lane road, which has a $5.2{\sim}5.5\;dB(A)$ difference compared to a 8 lane road, and set 2 points for a 2 lane road and lower. If we set the standard floor plan as horizontal and a living room facing the roadside, the horizontal and living room facing the opposite side of the road is 1 point because it differs by 14.1 dB(A), and the vertical is 3 points since the difference is 5.3 dB(A). If we make grades by the distance, making standard the fifth floor with little soundproof effect from apartment to road, we observe a measurement below 2.9 dB(A) at a distance of less than 10 m and 5 dB(A), decreased at a distance of 20 m. Therefore, 4 points were given for less than 10m, 3 points for $10{\sim}20\;m$, 2 points for more than 20 m as we can apply the effect of a decay distance of line sound source and the decrease in noise effects of more than 6 dB(A), 1 point for more than 40m, and 0 points for more that 80 m since it is negligible. 28 apartments got 0 points because there is no effect of road traffic noise from other apartments, and 50 apartments where only the road at one side effect them got $5{\sim}10$ points. 4 apartments (17-2, 6-3, 10-4, 3-3) received over 20 points. 15 cases showed a difference between developer price and resale price, and 11 cases (73%) among them showed the same trend (price increases with a low road traffic noise restriction factor point) with the point of road traffic noise restriction factor. 4 cases demonstrated the opposite trend, showing price increases with a high restriction factor point. Among the 4 cases, case numbers 2,6 and 9 appear to be more affected by the location factor (business district) than the road traffic noise restriction factor, and case number 1 appears to be affected by the building factor (openness and direction).
This study aims to explore 'bluffing', one of the most important topics in order to ensure the objectivity, validity, reliability of scoring of constructed-response items. The author identifies the conception of bluffing, and classifies major types of bluffing on the basis of previous studies on the theoretical level. Next, the author analyzes empirically the bluffing strategies and types of learners on key terms of Korean Geography subject. Compared with the existing research reports, the result of this study shows a significantly lower average bluffing score. On the other hand, it is consistent in results of previous studies reported that average bluffing score is similar between genders and that those students who got highest grades did least bluffing. Actually bluffing types are classified into four categories: 'repeating the question' type, 'depending on a well-known or existing knowledge' type, 'applying some basic concepts regardless of understanding' type, and 'inducing scorer's basic beliefs' type. Some comments and suggestions are as follows. First, it is necessary to continue researches of the relations among bluffing and age, gender, grade, intelligence and learning styles. Second, it is required for scorers who score constructed-response items to develop and supply the scoring guide including analysis contents of bluffing types and cases, and increase opportunity for training. Third, we need to inquire the domain-specific bluffing types in geography subject based on the generalizable sample size.
