The amounts of carbon (C), nitrogen (N) and phosphorus (P) in relation to dry weight (D.W.) were measured in zooplankton from the large four rivers (Han R., Geum R., Yeongsan R. and Seomjin R.) during 2004~2008. The stoichiometry of total zooplankton in four river systems was highly variable. The ranges of average C, N and P-contents were $70{\sim}620mgC\;mg^{-1}$ D.W., $7.1{\sim}85.5{\mu}gN\;mg^{-1}$ D.W. and $2.5{\sim}7.4{\mu}gP\;mg^{-1}$ D.W., respectively. The mean C :N: P atomic ratios reflected large spatial differences. The C : P and N : P ratios of the zooplankton community ranged from 38 to 392 : 1 and from 4 to 65 : 1 in all sampling sites. Self-Organizing Map (SOM) was applied to the survey data, and the study sites were clearly classified into 3 clusters. Clustering was largely affected by the distribution pattern of C, N, P-contents, which is related with characteristics of river systems on the basis of stoichiometry.

The purpose of this study was to analyze the research trend in home economics education using network text analysis method. The 586 research articles published in the Journal of Home Economics Education Association between July, 2003 and December 2018 were examined using Neckinger 4, a social network analysis software. The frequency and centrality measures(degree centrality, closeness centrality, and betweenness centrality) were calculated for the words appeared throughout the whole period, and the centrality analysis and LAD(Latent Dirichlet Allocation) were conducted for the four sub-periods. The results are as follows: first, the most frequently appeared words are parents, culture, unit, health, career, consumption, practicality, etc. The words such as parents and management scored high in degree centrality; parents and male students in closeness centrality; and male students and units in betweenness centrality. Second, when divided into four periods, the words such as education, family, purpose, class, middle school, and school appeared most frequently across the periods; but some words such as 'purpose' (in period 3 and 4), or 'process' (in period 4) were salient only in certain periods. Third, the words with high centrality were consistent regardless of the types of centrality within each period. Fourth, the topic analysis using LAD showed that curriculum, textbook, family healthiness, teaching-learning, evaluation, dietary life, appearance management, and consumption were the topics consistently appeared across all periods. The topics have become diversified and deepened. New topics such as teacher training and safety appeared in later periods, possibly due to the curriculum and national policy changes, and housing as a less represented topic is suggested as an area that needs further research attention. This study has implication in that it allows researchers to identify the major research interests and the trends in research by researchers in home economic education.

Overexcitaility (OE) as a concept that is related to developmental potential, has been shown to differ by intelligence, gender, involvement in school programs and artistic interest in American populations of students. Overexitability, used to describe the five ways that people might experience developmental potential for emotional growth, are emotional, intellectual, imaginational, sensual, and psychomotor. Little is known about the profiles of groups of gifted learners outside of studies conducted in the United States. In order to better understand the emotional needs of Korean students, the purpose of this study was to determine the overexcitability profiles of students enrolled in four high schools, each with a different domain focus: math and sciences, visual and performing arts, and foreign languages. 341 subjects of this study completed the Overexcitability Questionnaire II. Multivariate Analysis of Variance (MANOVA) was conducted to determine statistical differences. The results showed that Mean scores of psychomotor, sensual and imaginational are highest in the Art High School, intellectual is highest in the Science High School and emotional is highest in the Foreign Language High School. There were significant differences among the schools. Each major also showed significant difference. The results showed that mean score of psychomotor is highest in the Dance major, sensual, imaginational and emotional are highest in the Drama majore and intellectual is highest in the Science major. The results showed that the mean scores of psychomotor, imaginational and intellectual are higher in the male students than female students. On the other hand the mean scores of sensual and emotional are higher in the female students than in the male students.

Objective: The purpose of this study was to assess the effect of hospital-based pulmonary rehabilitation (PR) on exercise capacity and quality of life as well as barriers to participation in persons with chronic obstructive pulmonary disease (COPD) in South Korea. Design: One-group pretest-posttest design. Methods: A total of 14 patients were enrolled in this study in an 8-week PR program with two 60-minute sessions per week. The program included: flexibility exercises, breathing techniques, strengthening exercises, and aerobic exercises. The outcomes were defined as changes in the variables before and after the PR program. A change in the 6-minute walk distance (6MWD) was defined as the primary outcome, and changes in pulmonary function test, respiratory and grip strength, and the St. George's Respiratory Questionnaire (SGRQ) about quality-of-life results were secondary outcomes. A dropout was defined as missing >3 of the 16 sessions. Results: Patients who completed the program showed a significant improvement of 43.57±39.43 m in the 6MWD (p<0.05), but no significant differences were noted for the other function tests. The SGRQ showed a significant improvement in the activity and total score (p<0.05). The total dropout rate was 53.3%. Newly developed symptoms, exacerbation of COPD, transport problems, and lack of motivation were major barriers to PR. Conclusions: Our study showed that an 8-week hospital-based PR program improved exercise capacity and quality of life but had a high dropout rate in individuals with COPD. Since comprehensive PR has only recently been established in South Korea, patient motivation and education are critical.

This paper analyzed health practices of students in an university in Chollabukdo Province. It attempted to study how many university students had what kinds of health practices. Furthermore, it tried to find out what are the major problems in health practice among university students. To study health practices of university students, this study sampled 1,469 students randomly. Many of the students had poor practices of teeth care. In tooth-brushing, many students (35.8%) brushed their teeth before breakfast in the morning. Most of the students (95% or more) visit dental clinic only when they had problem(s) in their teeth. For weights, there exists a great gap between perception and BMI (Body Mass Index), especially among female students. Among the female students who perceived their weights were above average, 96.4% of them were normal according to BMI. Many of the students were drinking greater amount of alcohol than safe amount suggested by the National Health and Medical Research Council of Australia. The proportion of the students drinking harmful or hazardous amount of alcohol were 79.5% of the male students and 74.9% of the female students. It suggests that health promotion fund or tax need to be levied on alcohol to frustrate unhealthful drinking. More than half (59.0%) of the male students and about 6.0% of the female students were smoking cigarettes. The smoking initiation ages were 17.8 for male and 18.2 for female students. It means that many of the students started smoking in their junior high or high schools. It implies that smoking prevention and smoking cessation programs need to be emphasized in these schools. For perception on sex, 27.8% of the male students and 60.9% of the female students thought to keep their virginity before their marriage. The female students were more conservative in perception on sex. The average number of sexual intercourses per year of male students was 17.0 times with their lovers, 7.9 times with prostitutes, and 7.0 times with maids. The female students had sexual intercourses 5.0 times with their lovers and 4.0 times with waiters per year. The proportion of students who had experience of sexual intercourse with homosexual partners was 1.0%. The finding this study was that the university students were vulnerable to poor health practices. It is suggested that public health intervention program be provided for university students to keep them in good healthy lifestyle.

The optimal condition for preparation of powdered calcium acetate (LCCA) which has high solubility, from calcined powder (LCCP) of the littleneck clam shell by response surface methodology (RSM) was examined. Increased molar ratio of LCCP led to reduced solubility, yield, color values, and overall quality. The critical values of multiple response optimization of independent variables were 2.57 M of acetic acid and 1.57 M of LCCP. The actual values (pH 7.0, 96.1% for solubility, and 220.9% for yield) under the optimized condition were similar to the predicted values. LCCA showed strong buffering capacity between pH 4.89 and 4.92 on addition of ~2 mL of 1 N HCl. The calcium content and solubility of LCCA were 21.9-23.0 g/100 g and 96.1-100.1%, respectively. The FT-IR and XRD patterns of LCCA were identified as calcium acetate monohydrate, and FESEM images revealed an irregular and rod-like microstructure.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. The subjects of this study were 510 employees in 1 University Hospital and 3 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from April 26 to May 7, 2004 through survey questionnaires. The main results of this study were as follows: First, From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In University hospitals, males than females, and those who had senior officer posts in labor union showed higher positive correlation with the attitude of their colleagues. In general hospitals, those who had served in Union for shorter period showed higher commitment in union. Second, When looking into the major influencing factors on the level of commitment in labor union according to their jobs, male administrators showed higher positive correlation in the level of commitment in labor union and the relationship with union. Among nurses, those who had lower education level, those who had higher job satisfaction, those who had higher emotional attachment to their job, those who had better relationship with union and better satisfaction in union showed higher commitment level. In medical technicians, those who had higher emotional attachment to their job showed higher commitment level. To summarize study results, the level of commitment in labor union depends on job satisfaction, managers' attitudes, emotional attachment to their jobs, union satisfaction factors, their colleagues attitudes toward union and thee atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as job satisfaction is important determinant in union commitment, hospital managers should have countermeasures to enhance the job satisfaction level of hospital employees. Moreover, as managerial factors of the principal of hospital influence union commitment directly, the attitudes of hospital managers toward union and transparency of hospital management should be improved.

The purpose of this study is to get related appropriate data for correct awareness and education of the university students who are using contact lens by investigating university students' awareness, present status, using habits and complication of contact lens. The method of survey was made by questionnaires which were spread to the group of 408 university students. The result indicated some characteristics including using daily wear soft lens of 55.7%, the major motive of using them is for cosmetics of 45.6%. Among them, 54.9% experienced complication, and the xerophthalmia was the most conspicuous case in the aspect of the kinds of the complication. In the aspect of the place where they purchased the contact lens, 93% of the users bought them at eye glasses stores. But when they experienced inconveniences of the contact lens, only 18.8% consulted the Stores. In the fact, I think, the users don't seem to trust the stores fully. Furthermore, 43.5% endure the inconveniences when they get them without any treatment. The fact indicates that they don't realize the seriousness of the complication due to contact lens. Reviewing above-stated facts, information and education for correct awareness and managing methods of contact lens, the complication seem 10 be required. In addition, optician specialized knowledge on contact lens and the sense of duty on national eye health improvement seem to be required.
