Objectives: This study was conducted to investigate the prevalence of childhood obesity, the association between the undesirable lifestyles and socioeconomic factors, the association between childhood obesity and various risk factors, including socioeconomic factors, and the agreement between the body mass index (BMI) classification and the body fat percentage. Methods: The study subjects were all the 5th grade students from all the elementary schools in Gunpo City, Kyunggi Province, South Korea (4043 children at 22 schools). The subjects were measured for their height, weight and percent body fat etc. and they were also surveyed by questionnaire from March 18th to April 25th, 2005. To determine whether the children were within normal limits or not, standardized BMIs for each age group were used. The data was analyzed by logistic regression analysis using SAS 9.0 version. Results: The prevalence of childhood obesity prevalence was 25.1 %. Boys had a higher prevalence of obesity (27.5%) than did the girls (22.5%). Children had tendencies of having undesirable lifestyles and getting obese if they had a lower socioeconomic status. The risk factors for childhood obesity were low paternal education (OR: 1.17, 95% CI : 0.97-1.42) and non-parental caregivers (OR: 1.34, 95% CI : 0.98-1.82). Other risk factors for childhood obesity were a high birth-weight, longer TV/computer-using time, a lower fruit-eating frequency, short sleeping hours and parental obesity. The agreement rate between the BMI classification and the body fat percentage was 93.1 %. Conclusions: This study showed the children had a higher prevalence of obesity: further, not only individual lifestyles, but also socioeconomic factors could influence childhood obesity. Childhood obesity was especially more problematic for children with a low socioeconomic status.
Notwithstanding various discourses among scholars on the unique characteristics of comics, in Korea there is nevertheless a scarcity of quality research on the subject. Therefore, to promote quality research, it is important to consider how to best use source materials in the field of comics scholarship. Source materials can generally be categorized into three types: pre-existing comics, scholar-generated comics and user-generated comics. For this study, user-generated comics are the primary source materials, specifically comics created by mothers of children with disabilities. It is intended that this research will contribute to the future direction of education for mothers who suffer from a relative sense of alienation as the primary caregivers of children with special needs. Although therapeutic arts and cultural programs make a tremendous difference in the lives of these mothers, teaching methodology and educational opportunities are extremely limited. Furthermore, existing scholarship focuses primarily on either the psychological transformation of the individual or a phenomenological approach for parents to understand and deal with the problematic behavior of children with disabilities. However, this research does little to help improve learning programs for these parents. Against this backdrop, this research sets out to consider the potentiality and effectiveness of using comics in the education of mothers of children with disabilities. These mothers, by creating comics, develop better awareness of themselves in a positive and enriching way. It is therefore hoped that this research provides a useful analysis for developing the potentiality and effectiveness of these programs.
Eurasian eagle owl (Bubo bubo kiautschensis) is a natural monument (No. 324) and is also classified as an endangered wildlife grade II the Ministry of Environment of Korea. Eurasian eagle owl is threatened by the human being. But the efficient rescue and treatment for Eurasian eagle owl are still problematic, due to lack of basic data. In this study, to obtain basic resources for establishing more efficient rescue system, we held a physical examination and measured size physical part. In addition, we analyzed blood sample and feces samples and autopsy. We conduct the physical examination with measuring tapes and scales for 16 live features and 11 dead features. After inhalation anesthesia take the blood samples from wing vein. Blood samples are analyzed in hematologic and chemistric methods. We collected the feces through individual floor of cages from 12 live features and conducted the feces analysis. Autopsy was conducted for 11 dead samples. In physical examination, the mean body weight and total length of live features was 2.26${\pm}$0.35kg, 61${\pm}$2.38cm, the mean body weight and total length of dead features was 1.57${\pm}$0.51kg, 59.31${\pm}$3.51cm. Mean PCV was 46.57${\pm}$4.97%, while mean TPP was 3.49${\pm}$0.57g/dL. In feces sample analysis, 9 of 12 owls(75%) were infested by gastrointestinal helminths. The infection rates were: Trematoda (41.7%), Capilaria sp.(66.7%), acanthocephalans (25%). In autopsy, we confirmed 11 features were infested by duplicated infection of more than 2 helminths. Result of this study will be used for establishing reference range for physical features, blood analysis in Eurasian eagle owl. Therefore, to obtain basic resources for establishing more efficient rescue system, we have to make long-term conservation plans for Eurasian eagle owl.

Objectives : This study is to evaluate the status of health promotion behaviors and life styles in rural areas. Methods : A self-administered questionnaire survey was carried out for 1,350(men 461 persons, women ; 889 persons) people in rural areas ages of 30 years and older in Buk-myun, Uljn-Gun and Kikye-myun, Pohang-City, Kyungsangbuk-Do from March 13 to 25 in 1999. We established health promoting scores by using data results. Collected data was analyzed through the chi-square trend test, Student's t-test, ANOVA and multiple comparison. The data was analyzed using a SPSS/win statistical package. Results The age-adjusted prevalence of individual health promoting behavior by sex was 39.4% in men and 94.0% in women in regard to non smoking 39.4% and 92.5% in non-drinking 17.2% and 13.1% in physical exercise on a regular basis 79.8% and 80.0% in a regular diet 81.6% and 75.6% in maintaining desirable body mass index 81.2% and 78.2% in sufficient physical rest 84.2% and 82.1% in sufficient mental rest 48.4% and 40.6% in supplemental intake for health. The age-adjusted proportion for a screening examination in stomach cancer by sex was 39.9% in men and 37.1% in women 31.8% and 28.0% in liver cancer 17.0% and 12.7% in colon cancer 37.0% and 31.0% in undergoing a medical health screening. The health promoting scores were statistically significant, higher in the younger aged women's group(p<0.01). In spite of very low health promoting scores, some men thought of themselves healthy. Conclusions : The health promoting scores showed a gradual improvement as ages in men increase. Although men in ages of 30 to 40 were found to have lower scores in their health promoting scores, they were still to believe that none of health status is problematic. However, it was shown a vice-versa effect in women. They thought of their health as in a bad condition, but in measurement scores outranked their personal beliefs. In general, as ages increase one tends to consider of his or her health status poor. Therefore the plans for health improvement are needed to be come up.
This study is to diversely analyze teachers' Pedagogical Content Knowledge (PCK) regarding to the area of plane figures and discuss the consideration for the materialization of the effective class in learning the area of plane figures by identifying the improvements based on problems indicated in PCK. The subjects of inquiry are what the problems with teachers' PCK regarding to the area of plane figures are and how they can be improved. In which is the first domain of PCK, teachers need to fully understand the concept of the area and the properties and classification of the area and length, recognized the sequence structure as a subject of guidance and improve the direction which naturally connects the flow of measurement by using random units in guidance of the area. In which is the second domain of PCK, teachers need to establish understanding of the concept for the area and understanding of a formula as a subject matter object and improve the activity, discovery and research oriented class for students as a guidance method by escaping from teacher oriented expository class and calculation oriented repetitive learning. They also need to avoid the biased evaluation of using a formula and evenly evaluate whether students understand the concept of the area as a performance evaluation method. In which is the third domain of PCK, teachers need to fully understand the concept of the area rather than explanation oriented correction and fundamentally teach students about errors by suggesting the activity to explore the properties of the area and length. They also need to plan a method to reflect student's affective aspects besides a compliment and encouragement and apply this method to the class. In which is the fourth domain of PCK, teachers need to increase the use of random units by having an independent consciousness about textbooks and supplementing the activity of textbooks and restructure textbooks by suggesting problematic situations in a real life and teaching the sequence structure. Also, class groups will need to be divided into an entire group, individual group, partner group and normal group.
As a pioneering study on wife rape, this study focuses on identifying the prevalence, the correlates of the individual social class and domestic violence background, and the perception of wife rape. This study uses the data based on the survey 224 married men and women who reside in Daegu, Korea. The result of this study shows that about 42.4% married men have experienced any type of wife rape. The most prevalent wife rape is force only wife rape(36.4%). Battering rape(12.1%) and sadistic rape(10.4%) are also found as significant coercive sexual issue among Korean couples. Monthly income and child abuse experience are found as significant predictors for the wife rape of married men. In addition, wife's religious enthusiasm is also negatively correlated with wife rape propensity, although the effect is not strong. The living standards is found as a strong correlate of women's propensity of being raped from their husbands. Thus, our practical attention should be given to those who have financial difficulties in low economic status, and to those who have significant child abuse experience, in order to prevent wife rape. Overall, married men and married women show pretty negative perceptions of wife rape, however, some of them are still positive of it. It is interesting that married men show a very defensive attitude against the proposal of establishing legal punishment for the people who commit wife rape. According to the gender, there is a considerable difference between men and women in terms of both the degree of acceptance of, and the demand for legal punishment of wife rape. It is problematic that the married women with a greater experience of being raped by husbands show far greater tolerance of wife rape than those with a less experience of it. These findings give us significant practical implications for social work intervention.
In recent years, the subject of peer rejection in school settings has received increased attention in the massmedia and counseling literature. This study focused on the effect of individual and environmental factors on peer rejection. Dependent variable was the number of perpetrating peer rejection and independent variables were psychological, behavioral, familial factors, exposure of peer rejection and perception about school policies. Ordered Probit model was employed because of the nature of limited dependent variable. The data were collected from 714 middle-school student in Seoul. Major findings were as follows. First of all, the adolescents who has aggression and problematic behaviors in school were more likely to participate in peer rejection. Second, negative parent-children relationships and the family structure didn't have significant effects on peer rejection. And there were not a significant effect of attitude toward academic value and academic achievement on peer rejection. Third, environmental risk factors such as negative peer relationship and the exposure to rejection had a significant increasing effect on peer rejection. But consistent school policies didn't have a significant effect. In conclusion, this study confirmed that peer rejection in school settings was affected by school environment such as negative-peer relationship, and exposure to rejection. Therefore, comprehesive and systematic intervention programs should be required to ensure that all the pupils at school have a right to learn in a safe and fear-free environment.

This research sought to analyze the food waste collection and transportation system in Korea's related public resource-making facilities, address related problems, and suggest a reasonable alternative measure. For the food waste sorting-out and discharging methods, apartments and similar housings use containers, and individual-style housings use 'quantity-proportional' bags. The sorting and discharging methods should be improved to boost the reuse of resource-made output. The analysis of collection and transportation costs by local governments indicates that they range from 30,000 won to 150,000 won per ton, varying greatly by characteristics of local governments, thus suggesting a need to establish costs calculation criteria to justify the costs. Charges imposed to each household were not greatly problematic in the case of quantity-proportional bags; however, in the case of apartments and similar housings, charges varied greatly, suggesting a need to impose differentiated charges calculated on the basis of collection and transportation costs according to regions. Many places used household-garbage collection vehicles to collect food waste, raising the possibility of causing complaints on leaching water and bad odors. Thus, exclusive food waste collection vehicles should be gradually introduced. Also, in certain places, vehicles should travel more than 20km to collect food waste, and in such cases, a cargo transferring system should be introduced to boost efficiency in carriage.
A number of schools have introduced the Reward and Punishment Mark System. It has been applied to children at school in order to minimize the ill effects that are often caused by physical punishment. In this case, teachers have caused problematic issues in the course of student life guidance at school. However, the application of the personal Reward and Punishment Mark System raises many other questions as well. Accordingly, there is the necessity of making up for its weak points on the systematic level. The purpose of this study is to understand the Effect of the Collective Reward and Punishment Mark System, as a substitute punishment to the physical punishment, applying the reward and punishment mark system not to an individual but to a group. The Collective Reward and Punishment Mark System for the upper grade students of primary schools showed a positive effect which assists their adaptation to school. To put it more concretely, according to the characters of the study subjects, the system has proved that boy students are more positively affected than girl students. It has been also revealed that those students in the fourth grade experience a positive change in all areas of the adaptation to school, while those in the fifth and the sixth grade were negatively affected. Moreover, those who hold a lower rank in respect of grade achievement experienced a more positive change than those standing among a high rank. It is expected that the Effect of the Collective Reward and Punishment Marks System, on the basis of the study, possesses affirmative intervention on the field.

The impact of a journal is commonly used as the impact of an individual paper within that journal. It is problematic to interpret a journal's impact as a single paper's impact of the journal, so there are several researches to measure a single paper's impact with its own citation counts. This study applied 8 impact indicators to Korean Citation Index database and examined discipline bias of each indicator. Analyzed indicators are simple citation counts, PageRank, f-value, CCI, c-index, single publication h-index, single publication hs-index, and cl-index. PageRank has the least discipline bias at highly ranked papers and journal bias in a discipline. On the contrary, simple citation counts showed strongly biased results toward a certain discipline or a journal. KCI database provides only simple citation counts. It needs to show PageRank (global indicator) to discover influential papers in diverse areas. Furthermore it needs to consider to provide the best of local indicators. Local indicators can be calculated only with papers in users' search results because they uses citation counts of citing papers and the number of references. They are more efficient than global indicators which explore the whole database. KCI should also consider to provide Cl-index (local indicator).
