Establishing nursing professionalism is important for providing quality nursing care in various clinical settings and adapting to changing roles in a range of situations. The aim of this study was to identify the influence of volunteer activities and sense of community on nursing professionalism for nursing students. A convenience sampling method of 160 students in a nursing department of university in D city was used in June 2019. Data were analyzed using a t-test, ANOVA, Pearson's Correlation Coefficients, and hierarchical multiple regression analysis. The results of this study were as follows. The nursing professionalism score was above the middle level and differed according to the volunteer motivation and activity continuity significantly. Satisfaction with volunteer activities had a significant positive correlation with a sense of community (r=.47, p<.001), and nursing professionalism had a significant positive correlation with the satisfaction with volunteer activities (r=.51, p<.001). The factors affecting nursing professionalism were a sense of community (p<.001) and satisfaction with volunteer activities (p<.001); this model could explain 37.9% (F=20.38, p<.001). Therefore, nursing students are encouraged to participate voluntarily in a range of activities linked to their field, nurture a sense of community, and develop nursing education programs that help build pride as a nurse and establish nursing professionalism.

This study identified the differences and relationships between clinical practice stress, sleep quality, and daytime sleep disorder before and after clinical practice of college nursing students. The subjects were 130 students in the third year of nursing science. The results showed that the average clinical stress of the study subjects was 3.15 out of 5 points. Out of the external factors for clinical practice stress, the score for the task was 3.64. There was a significant difference in gender (t=-3.88, p<).001), subjective health status (F=5.78, p=.004), residence (F=3.20, p=.026). Nursing students showed lower sleep quality (80.0% before practice, 70.0% after practice), and those with daytime sleepiness (26.9% before practice, 42.3% after practice) were more than those of general college students. There was a difference between sleep quality (χ²=4.06, p=.004) and daytime sleepiness (χ²=6.08, p=.009) before and after clinical practice. There was also a negative correlation between daytime sleepiness and sleep quality (r=-.259, p<0.01). Therefore, strategies to reduce clinical practice stress and improve the quality of sleep are needed for the physical and mental health of nursing college students. The quality of nursing can be improved in the future by helping nursing students adapt to the clinical practice of changing nursing education field.

Club activities play an important role for college students in adapting to their college life. This study was therefore undertaken to investigate the effects of club activities on the communication skills and self-leadership of nursing students. Convenience sampling method was applied for 147 students enrolled in the nursing department of university in D city, of which 119 subjects participated in club activities. Data was collected from October 15 to November 30, 2019, and analyzed by applying 𝑥² test, t-test, and hierarchical multiple regression analysis, using the IBM SPSS/WIN 22.0 program. Results: Communication skill and self-leadership were above the middle level. Depending on the club activities, significant differences were obtained for grade (𝑥²=8.07, p=0.045), major satisfaction (𝑥²=8.26, p=0.010), and communication skill and behavior-focused strategies (t=4.48, p=0.036). Factors affecting communication skill were behavior-focused strategies, constructive thought pattern strategies, and activeness amongst club activities. Therefore, the numerous club activity experiences of subjects helped improve the communication skill which, in turn, helps improve self-leadership. Our study indicates the necessity to seek an educational strategy that encourages active club activities of nursing students, for improving the core competencies of professional nurses, encompassing communication skills and self-leadership.

$^{131}I-6{\beta}$-iodomethyl-19-norcholesterol(NP-59) has an advantage to assess adrenal dysfunction caused by adrenal cortical disorders. The aim of this study is to evaluate the clinical usefulness of NP-59 scintigraphy in each adrenal disease. Ten patients who did eleven NP-59 adrenal scintigraphies at Dong-A University Hospital from March 1990 to December 1996 were selected as the subject. Among the subject there were 5 cases of Cushing's syndrome, 2 cases of incidentaloma, 1 case of metastatic adrenal tumor, liver cirrhosis with hirsutism and hypertension respectively. Among 5 cases of Cushing's syndrome, there were 2 cases of Cushing's disease, 2 cases of adrenal adenoma and 1 case of adrenal carcinoma. There are no disagreement between clinical diagnosis and scan finding in Cushing's syndrome. In 2 incidentaloma cases, even though one is interpretated as a functioning tumor, both of 2 cases could avoid unnecessary biopsy according to scintigraphy result. One case of hirsutism, clinically adrenal originated, revealed the normal scintigraphic finding after dexamethasone suppression scan. It could suggest that the etiology of hirsutism was extra-adrenal origin. One case of hypertension took the study to exclude the possibility of primary aldosteronism. Normal suppression scan finding revealed that primary aldosteronism did not exist in this case. In conclusion, NP-59 scintigraphy was very useful in diagnosis and differential diagnosis of Cushing's syndrome and it could avoid unnecessary biopsy in the incidental adrenal tumor.

Currently Science and technology are changing so fast these days, educating competent and creative person, majoring in natural sciences, including mathematics., becoming more and more important. But, in Korea, there are many problems in high school and university education program, so performance level in mathematics is decreasing and avoiding mathematics and natural sciences is increasing. Naturally the numbers of science oritented students in high school are decreasing and ability in mathematics, in particular calculus, is decreasing. Hence, the above situation leads to a reduction of scientific manpower. In this point of a view, we analyse the situation of the downturn of the ability of the science, especially calculus, among engineering majored freshmen. We also study many data reported by Ministry of Education and Science, Korea and scholar societies. From this study we conclude that the essential rerasons for the above situations are curriculum and the system of the entrance examination of the university, and we give suggestions for solutions of such a situation.

Usually the persistence of ventricular activity in Tc-99m DTPA cisternography is deter mined using 24 hour images in our country. However, the 24 hour image is regarded as an in-sufficient data by many investigators. They prefer 48 hour image. The aim of the present study was to evaluate the feasibility and usefulness of 48 hour delayed imaging in Tc-99m DTPA cisternography. We performed 48 hour cisternography using Tc-99m DTPA in 38 patients with known hydrocephalus. 37-111 MBq (1-3mCi) of Tc-99m DTPA were injected by lumbar puncture. Anterior and both lateral Images were obtained at 2, 6, 24 and 48 hours. The classification of hydrocephalus was done at 24 and 48 hours by two independent nuclear medicine physicians. The 48 hour images were interpretable in all cases. In seven patients, the clearance of ventricular activity was noted only on 48 hours images. Therefore, their classification was changed from type W to type III. Sixteen of 38 patients were underwent shunt operations. Clinical improvement was noted in 13 patients(1/1 of type II, 3/6 of type III 8/9 of type IV). One case who showed a changing pattern from IV to IIIa showed no clinical improvement after shunt operation. In conclusion, the 48 hour delayed imaging was feasible and useful technique in Tc-99m DTPA cisternography.

This study attempted to implement fundamental data to understand the relationship between self esteem and stress-coping strategies of current students in health related colleges for the development of a program related to school life and guidance. This study involved 244 willfully participating college students from six health related colleges in the Honam area. Data from self administered questionnaires regarding self esteem and stress-coping strategies were collected from November 1 to December 21, 2008. The results of the study showed self esteem was high when general characteristics of religion and a very harmonious relationship with classmates were present. Higher usage of active stress-coping strategies occurred as the year in college and mother's education increased. Active implementation of passive stress-coping strategies were used when religion and residing in rural areas were present. Self esteem was higher as active stress coping strategies (i.e. problem focus and social support) improved. As passive stress-coping strategies (i.e. emotional relief and desire management) improved so did self esteem. By and large as stress-coping strategies increased for college students so did self esteem. As a result, as we search for stress-coping strategies pertaining to studies, practices, and future employment of college students, preparation of a regular course of study that includes curriculum, which increases self esteem should be made. Also consideration should be given to programs that promote relations between students and students and their advising professors.

Interspecific crossing was conducted to obtain hybrid lilly with better quality of adapting to the unfavorable environment using oriental Lilium spp. as a female parent. Average interspecific crossing rate between oriental and asiatic lines by cut-style pollination was as low as 29%. Although the average germination rate of zygotic hybrid embryo between oriental 'Rodolfa' ${\times}$ asiatic 'Toronto' was increased from 76.6% to 78.3%. on 114 or 1/6 strength MS medium compared to the control, the rate of zygotic embryos formation between oriental 'Farolito' ${\times}$ asiatic 'Buff Pixie' was significantly enhanced up about 86~90% on 1/2 strength MS medium. Meanwhile, germination rate of interspecific hybrid embryo between oriental 'Snow Cristal' ${\times}$ asiatic 'Royal Trinity' showed up 100%. Germination rate of interspecific hybrids slightly increased by addition of $0.5-1.0mg{\cdot}L^{-1}$ GA. Germination rate of zygotic embryos between oriental 'Farolito' ${\times}$ asiatic 'Buff Pixie' and oriental 'Belcanto' ${\times}$ L. callosum was highest on the MS medium containing $0.01mg{\cdot}L^{-1}$ NAA and $0.1mg{\cdot}L^{-1}$ kinetin, as 66.6% and 45.2% respectively.
