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

The purpose of this study was to investigate the effects of the constructivist instructional model on the acquisition of atmospheric pressure conceptions and learning motivation. The step of constructivist instruction was prediction and explanation-experiment and observation-discussion-application. The control group consisted of two classes of students who participated in the teacher-centered instruction. The experimental group consisted of two classes of students who participated in the constructivist instruction. To examine students' preconceptions before the instructions, a preconceptions test was administered. After the instructions, students' acquisition of atmospheric pressure conceptions and learning motivation were measured with a researcher-made post-conceptions test and The Course Interest Survey. The results from this study were as follows: First, the constructivist instruction is more effective method in acquisition of atmospheric pressure conceptions and learning motivation than the teacher-centered instruction. Therefore, in order to increase the acquisition of science conceptions and to decrease the science misconceptions, we need to use the constructivist instructional model which make learners self check their own preconceptions of science. Second, the constructivist instruction is more effective than teacher-centered instruction in three elements of learning motivation. So, we need to develop the effective ARCS(attention, relevance, confidence, satisfaction) strategies in order to use the constructivist instructional model and to verify it's effectiveness. Third, to improve teaching and learning methods, educational researchers should carry out studies using many points of view than studies biased constructivism or objectivism. In this respect, we need to contrive how to integrate constructive view points and objective view points.

Objectives: Understanding the situation of cancer awareness which doctors give to patients might lead to prognostic prediction in cases of of colorectal cancer (CRC). Methods: Subsets of 10,779 CRC patients were used to screen the risk factors from the Cancer Registry in Pudong New Area in cancer awareness, age, TNM stage, and gender. Survival of the patients was calculated by the Kaplan-Meier method and assessed by Cox regression analysis. The views of cancer awareness in doctors and patients were surveyed by telephone or household. Results: After a median observation time of 1,616 days (ranging from 0 to 4,083 days) of 10,779 available patients, 2,596 of the 4,561 patients with cancer awareness survived, whereas 2,258 of the 5,469 patients without cancer awareness and 406 of the 749 patients without information on cancer awareness died of the disease. All-cause and cancer-specific survival were poorer for the patients without cancer awareness than those with (P < 0.001 for each, log-rank test). Cox multivariate regression analysis showed that cancer concealment cases had significantly lower cancer-specific survival (hazard ratio (HR) = 1.299; 95 % confidence interval (CI): 1.200-1.407)and all-cause survival (HR = 1.324; 95 % CI: 1.227-1.428). Furthermore, attitudes of cancer awareness between doctors and patients were significantly different (P < 0.001). Conclusion: Cancer concealment, not only late-stage tumor and age, is associated with a poor survival of CRC patients.

The present study was carried out to investigate the potential acute toxicity of CKD-602 by a single intravenous dose in Beagle dogs. The test chemical was administered intravenously to male and female Beagle dogs at dose levels of 0.3, 0.5, or 2.5 mg/kg. Mortalities, clinical findings, and body weight changes were monitored for the 14-day period following the administration. At the end of 14-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. All males and females of the 2.5 mg/kg dose group were found dead between the fourth and seventh day after the injection. Treatment related clinical signs, including vomiting, anorexia, mucous stool, diarrhea, and no stool were observed. Decrease or suppression of body weight was observed in a dose-dependent manner. In autopsy, dark red discoloration of the gastrointestinal tract, atrophy of the thymus, paleness of the spleen, sporadic dark red spots of the lung and petechia of the heart were observed in dead animals of the 2.5 mg/kg dose group. There were no specific adverse effects on males and females of the 0.3 and 0.5 mg/kg dose groups, except for the transient clinical signs such as anorexia, vomiting, and mucus/no stool. On the basis of the results, it was concluded that a single intravenous injection of CKD-602 to Beagle dogs resulted in increased incidence of abnormal clinical signs and death, decreased body weight, and increased incidence of abnormal gross findings. The absolute toxic dose of this chemical was 2.5 mg/kg for both genders. The $LD_{50}$ value was 1.1 mg/kg (95% confidence limit not specified) for both genders. The no-observed-effect level (NOEL) was considered to be below 0.3 mg/kg for both genders.

The study aimed to explore how to improve mathematical thinking through metacognitive learning by stressing metacognitive abilities as a core strategy to increase mathematical creativity and problem-solving abilities. Theoretical exploration was followed by an analysis of correlations between metacognitive abilities and various ways of mathematical thinking. Various metacognitive teaching and learning methods used by many teachers at school were integrated for sharing. Also, the methods of learning application and assessment of metacognitive thinking were explored. The results are as follows: First, metacognitive abilities were positively related to 'reasoning, communication, creative problem solving and commitment' with direct and indirect effects on mathematical thinking. Second, various megacognitive ability-applied teaching and learning methods had positive impacts on definitive areas such as 'anxiety over Mathematics, self-efficacy, learning habit, interest, confidence and trust' as well as cognitive areas such as 'learning performance, reasoning, problem solving, metacognitive ability, communication and expression', which is a result applicable to top, middle and low-performance students at primary and secondary education facilities. Third, 'metacognitive activities, metaproblem-solving process, personal strength and weakness management project, metacognitive notes, observation tables and metacognitive checklists' for metacognitive learning were suggested as alternatives to performance assessment covering problem-solving and thinking processes. Various metacognitive learning methods helped to improve creative and systemic problem solving and increase mathematical thinking. They did not only imitate uniform problem-solving methods suggested by a teacher but also induced direct experiences of mathematical thinking as well as adjustment and control of the thinking process. The study will help teachers recognize the importance of metacognition, devise and apply teaching or learning models for their teaching environments, improving students' metacognitive ability as well as mathematical and creative thinking.

The purpose of this study was to confirm how the students have responded to their class according to STEB (science teaching efficacy belief) of secondary science teacher in astronomy classes. Middle school teachers in charge of 'The Solar System' and 'The Exosphere and Space Development' in the 2009 Revision Science Curriculum content system is selected as an object of study through random sampling method. Twenty-nine teachers were taken STEB questionnaire and asked to make it out. Twenty-seven completed a questionnaire of them is selected for this study. In addition, the top and bottom 5% selected through frequency analysis with the total score from the questionnaire were regarded as high and low STEB teachers. For data collection, this study was used methods such as semi-structured interviews, recording, participant observation. The results were as follows: First, science teachers of high STEB had a high accessibility about excellent professional knowledge and content of the curriculum relating to astronomical field. Second, high STEB teachers were prepared by the appropriate teaching strategies adequate to student-centered learning, whereas the low STEB teachers totally have had teacher-centered learning. Third, high STEB teachers had been provided as the idea that you can take advantage of a variety of instruments, as well as scientific knowledge through the Astronomical Society. Therefore, confidence in astronomical class and teaching strategies through content of the curriculum were very important variables to predict the STEB as well as astronomy-related class activities such as astronomical observations.

A long-term change in the evaporation rate have an influence on the hydrologic processes at the interface between the land surface-air and crop yield. Several previous studies have reported declines in pan evaporation rate, while actual evaporation rate is expected to increase due to anthropogenic global change in the future. The decreasing trend of pan evaporation rate might be involved with global warming and accordingly the trend of annual pan evaporation rate also needs to be checked here in Korea. In this study, 14 points of pan evaporation observation are intensively studied to investigate the trend of pan evaporation for the time period of 1970-2000. Annual pan evaporation is decreasing at the rate of 1.6mm/yr, which corresponds to approximately 50mm for 30 years. Annual pan evaporation rate is larger by $\sim10%$ at the coastal area and decreasing rate is faster as -2.46 mm/yr per year, while that is -0.82 mm/yr per year at the in-land area. The results of the Mann-Kendall trend test shows 4 points are decreasing and 10 points are unchanged with 95% confidence interval. But national annual average values show the decreasing trend of pan evaporation rate as a whole, which corresponds to general trend all over the world. This study will contribute to a variety of studies on water resources, hydrology, agricultural engineering, meteorology, and coastal engineering in association with future global climate change.

Leadership includes many program outcomes, especially soft skills, such as communication skill, team work skill, and etc. This paper studied leadership education program in Yeungnam University. In particular, this research was conducted by using focus group interviews with experts and working level staffs of relevant organizations for the analysis of Yeungnam University curriculum and non-curriculum courses related to leadership education and for the preparation of leadership education CQI method. In addition, we conducted leadership competence diagnosis, leadership education demand survey and satisfaction level survey on the leadership camp participants. Interviews with experts, lecturers and focus group of Dale Carnegie Research Institute Daegu branch that administered the progress of leadership camp were conducted along with analysis of education contents through non-participation observation method during camp period and participant students interviews. The conclusions are summed up as follows: To educate global leaders in true meaning, first, psychological level competence strengthening method and study completing ability improvement method should be considered simultaneously. In particular, for non-capital region universities, emphasis should be given to education for self-confidence and vision establishment. Second, leadership education methods of mid/long term and systematic curricular and extra-curricular type should be pursued. For instance, with the use of engineering design subject completing system, leadership education can be consolidated to engineering subject courses with engineering design projects or the system of mentor-pupil among earlier leadership camp participants and later participants may be utilized. Third, it is determined necessary to pursue and realize practical methods of conducting various intramural leadership related education activities in mid/long term perspective by organizing leadership education advisory group consisting of major, departments and intramural and extramural relevant organization authorities that focus on leadership education.

The present study was carried out to investigate the potential acute toxicity of amitraz by a single subcutaneous dose in beagle dogs. The test chemical was administered subcutaneously to male beagle dogs at dose levels of 0, 2, 10, or 50 mg/kg. Mortalities, clinical findings, and body weight changes were monitored for the 14-day period following the administration. At the end of 14-day observation period, hematology, serum biochemistry, and gross postmortem examinations were examined. A single dog in the 50 mg/kg group was found dead on day 3 after treatment and the other two dogs in the group were sacrificed because of the severe clinical signs on day 7 after treatment. Treatment related clinical signs, including anorexia, edema, mass and abscess formation in the injection sites, depression, vomiting, lacrimation, decreased locomotor activity, ataxia, recumbency, paresis in the limbs, and/or moribundity were observed in all treatment groups in a dose-dependent manner. Decreased or suppressed body weight gain was also observed dose-dependently in all treated groups. In autopsy, dead animals in the 50 mg/kg group showed muscular hemorrhage and inflammation in the injection sites and congestion in the liver and kidney. The terminal sacrificed animals in the 10 mg/kg group also exhibited muscular hemorrhage and inflammation in the injection sites. Whereas, no treatment related effects on hematology and serum biochemistry were observed on day 14 after treatment at any dose tested. On the basis of the results, it was concluded that a single subcutaneous injection of amitraz to beagle dogs resulted in increased incidence of abnormal clinical signs and death, decreased body weight, and increased incidence of abnormal gross findings. In the experimental conditions, the $LD_{50}$value of amitraz was 22.3 mg/kg (95% confidence limit not specified) and the no-observed-adverse-effect level (NOAEL) was considered to be below 2 mg/kg for male dogs.
