The purpose of this study is to verify empirically whether or not the linguistically creative problem-solving ability progress by developing and applying an enrichment learning program for the verbally gifted elementary school students. The total number of the verbally gifted students who participated in this study were 60 children. Half of them were subjects for evaluating the appropriateness of the enrichment learning program and the verbally creative problem-solving ability test developed by the researcher. The other half were divided into three groups for applying the teaching materials by Korean Educational Development Institute, the enrichment learning program by the present researcher, and the textbook enrichment program. The data were analyzed by the statistical method of repeated measures ANOVA. The results were as follows: First, the enrichment learning program developed by this researcher has greatly contributed to the advancement of verbally creative problem-solving ability. The program was especially effective in reading and writing, but not in speaking. second, the sub-category of reading includes factual, inferential·critical, and imaginary understanding. Among them, factual and imaginary understanding had not significantly advanced, while inferential·critical understanding had significant progression. Third, it was found that both logical and creative expression did not improve significantly by the enrichment learning program developed by the present researcher. Speaking is difficult to instruct. In conclusion, it was found that the systematic enrichment learning program was effective in developing language skills of the verbally gifted elementary school children. It was also proved to be more effective to teach them reading and writing together in everyday life. Also, it was turned out that continuous development of the enrichment learning program for the verbally gifted students is needed.

Purpose: The purpose of study is to estimate the number of chronic disease patients and medical care expenditure at the time baby-boomers belong to 65 years old aging population, and compare with current 65 year-old aging population. Methods: Analysis method used an estimating formula devised by the researcher and estimated the number of chronic disease patients and medical care expenditure of each generation. Results: When comparing the estimated number of chronic diseases patients of each generation, 40.6% of the first generation, 76.4% of the second generation, 95.2% of third generation are expected to get chronic disease. When comparing each generation's total medical care expenditure, based on the estimated number of chronic diseases patients of each generation, the second generation( 1,206,251,224 thousand won) showed higher than other generation. This study compared the number of chronic disease patients and medical care expenditure between the second generation of the elderly and current elder generation. As a result, the second generation patients was higher than the fourth generation in high blood pressure, diabetes, psychological and behavioral disorder, and neurological diseases whereas the fourth generation is only high the number of patients in heart disease. As for total medical care expenditure, the second generation paid more in high blood pressure, psychological and behavioral disorder while the fourth generation in neurological disease and heart disease. Conclusion: It is desired that considering the number of chronic disease patients and medical care expenditure of baby boomers accounting for 14.6% of total population, in-depth follow-up study is carried out that inquires into what are issues with a current chronic disease management project, what business is needed in order to manage these issues, and how to fund to cover increasing medical care expenditure.

The techniques of GIS and remote sensing are being applied to hydrology, geomorphology and various field of studies are performed by many researcher, related those techniques. In this paper, curve number change detection is tested according to soil map and land cover in mountain area. Neural networks method is applied for land cover classification and GIS for curve number calculation. The first, sample area are selected and tested land cover classification, NN(84.1％) is superior to MLC(80.9％). So we selected NN with land cover classifier. The second, curve number from the land cover by neural network classifier(57) is compared with that(curve number) from the land cover by manual work(55). Two values are so similar. The third, curve number classified by NN in sample area was applied and tested to whole study area. As results of this study, it is shown that curve number is more exact and efficient by using NN and GIS technique than by (using) manual work.

The performance of scientific researchers has been studied from a number of different aspects, mostly in developed countries. This paper attempted to identify salient factors influencing scientific performance at individual level in a developing country. A model describing the productivity and performance of scientific researchers was developed. Four hypotheses were derived from the model; i) the degree of diversity of a researcher will affect the degree of his scientific performance, ii) the degree of dedication will affect the degree of his performance, iii) the degree of research pressure will affect the degree of his performance, and iv) the degree of satisfaction will affect the degree of his performance. Data were collected through questionnaires responded by 48 researchers from two research organizations. The results of data analysis supported the hypotheses in part. Specifically, diversity measured by the number of research areas was related to the productivity of research reports (p<0.05); research pressure influenced the average number of research papers (p<0.05). The results of hypothesis testing of the satisfaction showed mixed directions according to the indicators. Even though the results of data analysis did not support the hypotheses unanimously, probably due to the limitation of sample size, most of the descriptive analysis indicated that the direction of hypotheses in developed countries seemed to be similar in developing country too. However, more research efforts are needed to verify the research findings of developed countries in developing countries.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS) is one of the powerful methods that enable analysis of small molecules as well as large molecules up to about 500,000 Da without severe fragmentation. MALDI-TOF MS, thus, has been a very useful an analytical tool for the confirmation of synthetic molecules, probing PTMs, and identifying structures of a given protein. In recent nuclear medicine, MALDI-TOF MS liner ion mode helps researcher calculate the average number of chelator(or linkage) per an antibody conjugate, such as DOTA-(or DFO-) trastuzumab for labeling a medical radioisotope. This simple technique can be utilized to improve the labeling method and control the quality at the development of antibody-based radiopharmaceuticals, which is very effected to diagnosis and therapy for in vivo tumor cells, with radioisotopes like $^{89}Zr$, $^{64}Cu$, and 177Lu. To minimize the error, MALDI-TOF MS measurement is repeatedly performed for each sample in this study, and external calibration is carried out after data collection.

This study investigated the extent of informational text genre appeared in English textbooks at grades six, seven, and nine. Employing content analysis to analyze the literary forms, the researcher identified genre in each reading selection of each English textbook and classified it into six categories - fiction, information, biography, poetry, play, or fantasy. Especially, informational genre was classified further into two subcategories - non-narrative and narrative - in order to investigate the extent of non-narrative informational text only. The text genre was examined by analyzing (a) the number of reading selections representing each genre and (b) the number of words in reading selections devoted to each genre. The most frequent type of genre at grade 6 and 7 was fiction with 94% and 71% respectively, whereas at grade 9 it was devoted to information (51%), followed by fiction (37%). The largest number of words was devoted to fiction with 96% at the sixth grade and 70% at the seventh grade; on the other hand, for grade 9, it was devoted to information (46%), followed by fiction (39%). Although there was variance across different publishers, the informational text genre gained more significance as the grade level increased. In particular, the percentage of reading selections and words devoted to the non-narrative or expository informational genre was overall 4% at grade 6, 17% at grade 7, and 44% at grade 9. The findings demonstrated the need to pay more attention to informational literacy especially in the early grades for the development of balanced genre knowledge.

The Necessity and Purpose of the Study Recently the number of patients with chronic diseases and the aged patients is increasing steadily. Furthermore, due to the expansion of health insurance system, the number of patients hospitalized in the general hospital is increasing at a surprising speed. However, hospitals urge the early discharge of the patients for the efficiencies of hospital administration, and therefore, the number of patients who must be taken care of in their home is also increasing. Homecare nursing is one of the health care service for the patients at home who require continual attention and care, and now increasing attentions are given to it as one of the professional nursing fields. However, it was almost impossible to find a study on the actual experiences of the homecare nurses written by their own language in Korea, that it also posed a great difficulty in understanding their diverse experience. Considering these situation, this study will help understanding of them, and provide the fundamental data on their experiences for making policies to develop homecare nursing. Methods of Research Phenomenological research method was employed to analyze the lived experiences of homecare nurses fundamentally. Data collection Data were collected from August 1998 to December 1998 from ten homecare nurses who worked for patients under the homecare nursing setting as model cases designated by Seoul Nurses Association and who agreed to the purpose of this study after listening to and understanding the explanation completely. The in-depth interview was carried at the time which was convenient both for the researcher and participants for one or two hours, and recovered with the approval participants. The first interview covered diverse and broad areas like the situation of homecare nursing, and their feelings and thoughts over it, and in the second and third interviews, more specific questions are asked. Data Analysis For the phenomenological analysis, contents analysis was employed. The data collected from the participants were analyzed into the following procedures according to Van Manen 's phenomenological analysis. 1) Reserve the preconception of the researcher by restricting it inside parenthesis. 2) Make a thorough observation of the lived experiences by insight process. 3) Analyze the contents (Find out the repetitive factors) 4) Interpret the essence found. 5) State the meaning of the interpretation. Results and discussion 1. Fear and expectation for the first visit. (unfamiliarity, awkwardness, anxiety, shivering) 2. Mingle with the family (feeling friendly with the family, becoming like a family member) 3. Being proud of her own know-how (learning the know-how, organizing alternatives, building up confidence) 4. Pity for the poor. (criticizing the current government, feeling ashamed, feeling anger) 5. Difficulty of constructing cooperative system with physicians (strenuousness, frustration) 6. Helplessness due to the lack of support system (difficulty to get supplies, annoyance, embarrassment by institutional restraints) 7. Anxiousness for heavy traffic and parking (annoyance, hastiness) 8. Ethical conflicts (pity for the patients and family, skepticism about lengthening life maintenance) 9. Burden for the possible accident (pressure, anxiety, conflict, physical exhaustion) 10. Establishment of identity as a professional (fulfillment, worth, joy) 11. Being distressed at other's ignorance
