Households' monthly average income is composed of various factors. This study paper studies focuses on estimating the determinants of a households' monthly average income. The region for analysis consist of three groups, that is, the whole country, a metropolitan city(such as Busan, Daegu, Incheon, Gwangiu, Daejeon, Ulsan.) and Seoul. Analyzing period be formed over a 57 time points(2005. 01~2009. 09). In this paper the dependent variable setting up the households' monthly average income, explanatory (independent) variables are composed of the consumer price index, employment to population ratio, Index of housing sale price, the preceding composite index, loans of housing mortgage, spending rate for care medical expense and the composite stock price index. In looking at the factors which determine the monthly average income, evidence was produced supporting the hypothesis that there is a significant positive relationship between the composite index and housing loans. The study also produced evidence supporting the view that there is a significant negative relationship between employment ratios, the house sale pricing index and spending rates for care or medical needs. The study found that the consumer price index and composite stock price index were not significant variables. The implications of these findings are discussed for further research.

This study is intended to look into the effects of children's problem behaviors on the coping strategies of teachers involved in early childhood education (ECE). To achieve this, a survey was administered to 90 teachers involved in ECE at kindergartens and child care centers in Daejeon Metropolitan City. The findings showed that these teachers have a professionalism and suitability for their career and excellent ability to cope with the problems of children in this age group. The results showed that competent teachers had less tendency to put children in the corner or give physical punishment to them than incompetent teachers. Competent teachers didn't use coping strategies involving scolding or saying no with a somewhat loud voice, but rather pointed to each word accurately or helped the children express their feelings and understand their situation. However, their coping strategies may not always be suitable in all situations. When necessary, saying no accurately with an accompanying warning is also important. Consequently, career and professional knowledge are important for teachers involved in ECE, and it would be useful to collate the diverse strategies that they use.

The present study was designed to evaluate the factors influential on stress and subjective fatigue symptoms based on school life environments and daily life styles among high school students. The self-administered questionnaires were delivered to 2,381 high school students of both sexes in Taejon Metropolitan city during the period from Mar. 1st to Jun. 30th, 2000. The analysis of study results revealed the following findings: 1. According to the magnitude of stress, the normal subjects were 3.1%, the groups with potential stress were 64.7%, and the groups at high risk for stress were 32.2%. Higher level of stress existed in the female than the male students, and in the third grader than the 1st and 2nd graders. According to the classification of typical constitutional symptoms of fatigue, category III (group with bodily projection of fatigue) was the most frequent and it was followed by category II (group with difficulty in concentration) and category I (group with dullness and sleepiness) in a decreasing order of frequency, which showed that the predominant pattern of fatigue arose from the body parts. 2. With regard to the school life characteristics and stress scores, the higher scores of stress were shown in the groups with the lower grades, with worse friend's relation and with the lower satisfaction with the school life. The scores for the subjective fatigue symptoms were higher in the male, in the low graders, in the better friend's relation, and in the satisfactory group than the respective counterparts. 3. Concerning home life characteristics, the higher scores of stress were associated with the students characterized by the recognized poor economic conditions, lower interests of parents, lack of satisfaction with the home life, the poor subjective health status. On the other hand, the scores for the subjective fatigue symptoms were higher in the student groups with good economic conditions, higher interests of parents, presence of satisfaction with the home life, and good subjective health status. 4. Concerning daily life styles, the higher scores of stress were in the students who had inappropriate sleep hours, skipped breakfasts, daily consumption of intermeal snacks, lack of exercise, daily smoking, normal indices of obesity, and lower indices of health habit. Conversely, the scores of subjective fatigue symptoms were higher in the groups who had daily breakfasts, no intermeal snacks, daily exercise, no smoking than their counterparts. 5. The factors exerting influence upon the stress included the satisfaction with school life, friend's relation, satisfaction with the home life, exercise, school grades, interests of parents, school year, sex, scores of health habit, degree of obesity, economic conditions of home. Those influencing on the degree os stress included stress, intermeal snacks, smoking, friend's relation and satisfaction with the home life.

This study investigated a long-term variation trend of water quality, fish compositions, and ecological health conditions in the Gwanpyeong stream located in the nearby Daejeon metropolitan city to understand the impact of urban development projects on the aquatic ecosystem. The sampling was made in four surveys (2009, 2010, 2016, 2019) before and after urbanization. The urban development was conducted in 2008, resulting in the stream's ecological disturbance, and the stream restoration was conducted in 2012. Thus, stream monitoring was conducted to analyze the ecological trends before and after the restoration. The multi-metric models for Fish Assessment Index(FAI) and necropsy-based Health Assessment Index(HAI) were applied in the fish community and organ-level, respectively, to assess the ecological health of the stream. Minimum turbidity and chlorophyll-a(Chl-a) occurred in the mid-stream(St. 2), and this was probably due to rapid current velocity in the riffle zone. We collected 18 fish species, and the dominant species was Zacco platypus (40.6%). In 2016 immediately after the stream restoration, the relative proportions of sensitive species and insectivore species were the highest along with highest values in the species diversity and species richness index, resulting in the best condition in the ecological health, based on FAI model values. However, the ecological health, based on the FAI, became worse in the latest survey conducted in 2019. The analysis of the HAI model based on the organ-level approach showed skin erosion in the fish of upper stream, kidney defects in downstream, and the liver and gill defects observed in all sites, indicating that the anatomical health was also affected.

The foster care system is a social welfare service that supplements the functions of the family while enabling children, who cannot receive proper care from their biological parents, to receive the necessary protection under the plan within the prescribed period of time within a substitute or foster family. A large part of the emotional instability experienced by foster care children is interpersonal maladjustment. Low self-esteem leads to difficulty in forming social relationships due to negative interpersonal relationships. Thus, the purpose of this study is to investigate the effects of traditional dance programs on the foster children who live in Daejeon Metropolitan City. A comparison between the pre- and post-interpersonal scores showed that the scores were improved after the traditional dance program, and the children's intimacy formation and communication were also improved. The participants were less active at the beginning of the program, but became more interested and more active toward the middle of the program. The majority of the participants increased their degree of communication with the formation of intimacy toward the middle of the program, and their self-confidence improved in terms of their peer relationships. The purpose of this study was to investigate the effects of traditional dancing on the development of interpersonal relationships. In a subsequent study, a traditional dancing program consisting of various contents will be applied over a long period of time, which should provide them with the opportunity to improve their interpersonal skills. In addition, it is necessary to provide educational opportunities for helping foster children reduce their emotional instability with systemic and diverse traditional dance programs.

The aim of this study was to find the factors related to smoking-cessation among citizens receiving smoking-cessation clinics' services in a public health center in Daejeon metropolitan city. The study subjects were 2,125 participants registered in "smoking-cessation clinic", public health centers in 2007. Frequency analysis, chi-squared test and multiple logistic regression analysis were used to determine the relationships between the success rate of smoking-cessation and the characteristics. The success rate of smoking-cessation during 6 months was 39.8%. Males had a higher rate than females, and people over 65 years of age had a higher rate than those less than 40 years of age. High blood pressure, drinking of more 2 times per week, regular exercise, CO under 10ppm had significantly relationships with the smoking-cessation rate. The other independent variables had no statistically significance with the smoking-cessation success rate. Logistic regression analysis showed that age, number of nicotine patches used and total consultation times had significantly relationships with the smoking-cessation success rate. The total consultation times showed the highest odds ratio than the other significant factors. This study suggests that regular consultations will be the most effective intervention towards maintaining smoking cessation programs of smoking-cessation clinics in public health centers.

An intestinal strigeiid trematode, Apharyngostrigea pipientis, was detected from Ardea cinerea jouyi, Egretta intermedia and Nycticorax nycticorax between July, 2006 and June, 2020 in Daejeon metropolitan city and Kangwon-do, Republic of Korea. It was observed with a light and scanning electron microscope (SEM), and molecularly analyzed with 18S rRNA genes. The infection rate of the strigeiid trematode was 25.9% (7/27). The body is cylindrical in whole mount, greatly elongated in outline and shows a strong dorsal curvature. The overall measurements are: length 4.1-4.8 mm; fore-body 1.00-1.20 mm by 0.8-0.9 mm; hind-body 3.2-3.6 mm by 0.43-0.46 mm. The body is covered by a relatively thick cuticle, devoid of spines. The oral sucker leads into a short esophagus that is devoid of a muscular pharynx. The holdfast organ is enormously developed. The vitelline follicles distributed dorsal wall of fore-body and hind-body. This strigeiid trematode especially differs from other species of genus Apharyngostrigea in morphology. Although these A. pipientis are several morphological distinctions from Apharyngostrigea cornu, the partial sequence of 18S rRNA showed the sequence homology of A. pipientis (99.9%) and A. cornu (99.8%), and this result revealed their conspecific relationship between A. cornu and A. pipientis. This is the first report of A. pipientis in the Republic of Korea.
