The aims of this study are to identify the perceptions and learning needs related to nursing profession of nursing students and to provide the basic data for development of curriculum. The questionnaire used for this study includes 103 items categorized as the fellowing 8 areas : the perception of nursing profession, competency as a nurse, the perception about clients, priorities in nursing activity, the knowledge required for, an ideology about nursing. Data was collected from the same students through their first grade in 1993 to third grade in 1995. The results are as follows : 1) In terms of the views on nursing profession, most of the students responded it as helping treatment of disease. Higher the grade, more significant with regard to health counseling, utilization of nursing and skills, nursing for community people. 2) Asked about competency as a nurse, sufficient professional knowledge on the nursing was responded as the highest. 3) Asked about the clients of nursing, 'patients' was the highest and as the grade was high, the items on 'family', 'community people', 'community' were high. 4) With regard to the points to be considered in the performance of nursing, while 'physical respect', 'psychological respect' were commonly responded, 'spiritual respect' highly responded in the second and third grades. 5) Asked about what nursing activity is, 'to relieve the pain' was high in the first and second grades, 'the promotion of health' was high in the third grade. 6) With regard to the ideology on nursing, the humanity and belief and faith were commonly responded. These results suggest, even though the expanded role of nursing was recognized, there is the tendency of illness oriented, to be need of reinforcement on the curriculum management in nursing education.

This numerical study demonstrates the porosity conditions and the intensity of the interactions with the aggressive agents. It is established that the density as well as the elastic modulus are correlated to ultrasonic velocity The following investigation assessed the effects of cement grade and porosity on tensile strength, flexural and compressive of Ultra High Performance Concrete (UHPC) as a numerical model in PLAXIS 2d Software. Initially, the existing strength-porosity equations were investigated. Furthermore, comparisons of the proposed equations with the existing models suggested the high accuracy of the proposed equations in predicting, cement grade concrete strength. The outcome obtained showed a ductile failure when un-corroded reinforced concrete demonstrates several bending-induced cracks transfer to the steel reinforcement. Moreover, the outcome also showed a brittle failure when wider but fewer transverse cracks occurred under bending loads. Sustained loading as well as initial pre-cracked condition during the corrosion development have shown to have significant impact on the corrosion behavior of concrete properties. Moreover, greater porosity was generally associated with lower compressive, flexural, and tensile strength. Higher cement grade, on the other hand, resulted in lower reduction in concrete strength. This finding highlighted the critical role of cement strength grade in determining the mechanical properties of concrete.

Background: A new admission procedure was introduced to Korea when Doctor of Pharmacy (Pharm. D.) program was first established in 2011. In the new procedure, applicants are reviewed based on quantitative qualifications, which include Pharmacy Education Eligibility Test (PEET) scores, Test of English for International Communication (TOEIC) scores, and grade point average (GPA), as well as qualitative qualifications such as essay writing, extracurricular activities including volunteer experiences. Purpose: This study aimed to find relationships between entrance qualifications and academic performance of pharmacy students. Method: Entrance qualifications and academic performance of 164 first-year students were analyzed from 2011 to 2013 at Catholic University of Daegu. Other characteristics such as age and gender were also considered in the study. Results: Only GPA and TOEIC scores showed positive Pearson correlation with academic performance, while PEET scores did not. Conclusion: GPA and TOEIC scores could potentially have predictive validity for academic performance in pharmacy school. PEET scores, however, should simply be considered as pre-entrance qualifications, without predictive validity for academic performance.

This study was conducted to provide the baseline data for preparing an educational program for mothers of pediatric asthma patients by identifying the knowledge about asthma, mother's educational demand and the perceived educational performance. This study used survey design. The subjects were chosen from the mothers whose children have received pediatric asthma treatment or who have admitted in the pediatric unit of major hospitals using selection criteria. The total number of subjects were 63 mothers. The data collection period was from May 1st, 2001 to April 17th, 2001. Instruments used for this study were knowledge examination, educational demand evaluation, and educational performance. The data were analysed using t-test, ANOVA with SPSS PC(Version 10.0). The results of this study were as follows. 1. Mean score of knowledge about pediatric asthma was 17.95, which suggests the mothers of children with asthma have a medium knowledge level. The highest grade was knowledge about treatment and follow management and the lowest grade was knowledge about diet. 2. Demand for education showed 4.23, which suggests the mothers of children with asthma have high educational demand. The highest score was about exercise and activity in daily life and the lowest score was medication. 3. Perceived educational performance score of themselves showed 2.40, which suggests the mothers of children with asthma thought that health team do not give enough education to them. The highest score was knowledge about pediatric asthma itself and the lowest score was exercise and activity in daily life. 4. Demand for education and perceived educational performance about pediatric asthma showed significant difference in all areas. 5. There were no statistically significant difference noted between general characteristics and degree of knowledge, educational demand and perceived educational performance about pediatric asthma. In conclusion, there needed a systematic educational program development for the mothers of children with asthma. Especially, an education program for mothers in the beginning period of pediatric asthma should be emphasized.

The purpose of this study is to analyze the relationship of logical thinking skills and integrated process skills, and to investigate the differences in general tendency of subskills by grade level and gender between Korean middle school students and Japanese one. The performance level of skills was measured using GALT and TIPS II. The results are compared with those of Japan (Mattheis et al., 1992). Summary of the results are as follow. 1. Percentages of formal and transitional stage of males are more than females in developmental level. It has been found out that the males attained significantly higher scores of logical thinking skills than the females in middle school stage. The significant differences in scores by gender show a good correlation with those for Japanese middle school students. Developmental level of Korean middle school students shows a remarkable improvement as they move up from 8th grade to 9 one. The significant differences in developmental level by grade also show a good correlation with those for Japanese middle school students. Total scores of GALT for Japanese middle school students are higher than Korean one, but it has been found nearly same scores for 9th grade in both countries. Scores of subskills of logical thinking skills, except correlational reasoning, for Korean students show lower than those for Japanese students. It could be noted that the combinatorial reasoning is considered to be easiest and the correlational reasoning to be most difficult in both countries. 2. It also has been found out similar pattern for integrated process skills in both countries because the males and females did not examplify significant differences, although males gain somewhat higher scores than females in Korea. Scores of subskills of integrated process skills for Japanese middle school students show higher them Korean one. It could be noted that the identifying variables is considered to be easiest and stating hypothesis to be most difficult in both countries. 3. There was a significant relationship (r= .65) between logical thinking skills and integrated process skills, and there were statistically significant differences of the integrated process skills for developmental level. In integrated process skills, the students who belong to the higher grade levels acquired better score than who belong to the lower grade level. It has been also found remarkable improvement between 8th and 9th grade, and there are significant differences for grade level in both countries.

This study was conducted to determine the effects of amino acid-enriched ruminally protected fatty acid (AARPFA) on plasma fatty acids and amino acids, growth performance and carcass characteristics of Korean native steers (Hanwoo) by simultaneous supply of fatty acids and limiting amino acids (methionine and lysine). Eighteen finishing Hanwoo steers, 18 months of age and weighing an average of $459.0{\pm}38.9\;kg$, were used for studies of the metabolism of plasma fatty acids and amino acids during supplementation of AARPFA. Also, 45 finishing Hanwoo steers, 16 months of age and weighing an average of $408.6{\pm}26.5\;kg$, were used for growth performance and carcass characteristics during supplemention of AARPFA. There were three treatments which comprised a basal diet supplemented with AARPFA at 0 g (T1), 50 g (T2) or 100 g (T3), respectively. Concentrations of saturated, unsaturated and total fatty acids in plasma were increased in T3 compared with other treatments (p<0.05). Concentrations of methionine and lysine in plasma were linearly increased with increasing levels of AARPFA (p<0.01). Average daily gain, dry matter intake and feed conversion ratio were not different among the treatments. Marbling score measured by ultra-sound scanning was higher in T3 than in T1 at 24 months of age (p<0.05). Rib eye area, back fat thickness, yield index and yield grade score were similar across the treatments. Marbling score and quality grade score were higher in T3 compared with other treatments (p<0.01). Thus, plasma fatty acids, methionine and lysine metabolism were affected by supplementing with 100 g of AARPFA which also had positive effects on marbling score and meat quality grade of finishing Hanwoo steers.
