  • This study examined the relationship between the demographic profiles of 260 staff nurses in the SPC Health Care Ministry Hospitals and their Transcultural Self-Efficacy (TSE) level on the Cognitive, Practical and Affective dimensions. To obtain the result, among the nine (9) demographic profile items, three (3) common positive predictors were considered, namely, 1) Educational attainment level; 2) Age; and 3) Willingness to work abroad in all three dimensions. While in the Practical and Affective dimensions, the number of years employed were a common negative predictor and in the Affective dimension, Gender of participants was added as the positive predictor. Therefore, there are some significant demographic characteristics of respondents influence to the transcultural self-efficacy. Further, based on the results of this diagnostic study, the researcher designed the One (1) year Cultural Competence Training Program for staff nurses. For future research, the researcher recommended to conduct a further study that will evaluate the effectiveness of the educational intervention by approaching a longitudinal study form administering the test and retest of TSET.

  • This paper presents at the characteristics of publications in the Journal of Astronomy and Space Sciences from 1984 to 2018. Since its first publication, a total of 1,113 papers (~35 volumes) have been published up to December 2018. While the space astronomy field has made up a large portion of the total number of papers, the number of annually published papers in this field is decreasing. In contrast, the number of papers in the space environment field has been showing an increasing trend since 2013, accounting for more than 30% of the annual publications. The participation rate of foreign researchers has been maintained at greater than 20% since 2012. Despite the decrease in the number of paper per year, there are positive developments including sustained foreign researcher participation at greater than 20% and improvements in the impact factor. We believe that JASS has the potential to enter the distinguished level of international academic journals following a well-developed future road map.

  • Recently, the oriental medicine industry in Korea has faced much hardship, due to the decreasing number of patients. Therefore, it is essential to investigate the reasons why patients are avoiding oriental medicine, because the percentage of people consuming medical service is an important marker that assesses the value of medical service. The researcher(s), based on theories on factors that affect health, health behaviors, and diseases, sought to find reasons why oriental medicine clinics saw a decline in the number of patients. Also, by proposing the problems inside the oriental medicine, I came to the following conclusion. -Because Koreans have low expectations for oriental medicine, they do not consider it as full medical service. Also, when they get sick, they are reluctant to seek oriental medicine because of reasons such as the limits of oriental medicine and check-ups, expensive medical cost, negative perception of oriental medicine, not enough support from the media, the old image of the oriental medicine and the little power the industry has on the society. -Among the inner problems of the oriental medicine community was the limitations that the science face on incurable and chronic diseases in terms of treatment and management, little professionalism, lack of scientific evidence, the attitude of the oriental medicine society, lack of sophistication in research methodology, and limitations in responding to changes in public health and the surroundings. The purpose of medicine is to eliminate the possibility of shortened life and dangers by treatment of diseases and health maintenance. For this to happen, structural and developed medical theories and means of treatment are necessary. The researcher hypothesizes that the problems that the oriental medicine society is facing mainly come from the lack of efforts and ability to provide such necessities.

  • The goal of this study is to discover the effect of sex education on sex-related knowledge and attitudes of middle school girls. Non-equivalent control group pretest-posttest design was used. The number of experimental group students was 134 and the number of control group students was 134. A total of 268 second grade middle school girls were selected for a convenience sampling method. This study was carried out in a middle school located in Taegu City, Korea, from February 5 to February 18, 1998. To des cover the needs of sex education, the researcher sent a predesigned questionnaire to 1464 girls in 19 different middle schools. The sex education curriculum was designed on the basis of this survey's results. 'The Sex Education Teaching Plan' (published by the Research Institution of Korean School Health Education) and 'Sex and Happiness' (published by the Seoul City Education Ministry) were used to redesign the sex education curriculum and content. Fifty minute long sex education classes were taught to the experimental group every other day and the total number of classes was five. The contents of the teaching -learning plan for sex education were: 'The Characteristics of Adolescence', 'Pregnancy and Contraception', 'Friendship with the Opposite Sex and Prevention of Sexual Violence', 'Prevention of Venereal Disease', and 'Sex and Society'. To measure the degree of sex knowledge of the subjects, the researcher used the modified sex knowledge tools of Kim(l995) and Han(1997). The reliability values of these sex knowledge tools range from 0.71 to 0.74, using Cronbach's alpha. To measure the degree of sex attitude in the subjects, the researcher used the modified sex attitudes tools of Han(l997). The reliability values of these sex attitude tools range from 0.73 to 0.78 using Cronbach's alpha. The PC-SAS package program was used to analyse the data along with Frequency, Percentage, XLtest, t -test, and a paired t -test The results of this study were as follows; 1. The first hypothesis was accepted. The experimental group showed more change in sex - related knowledge than the control group(t =22. 76, p=0.0001). 2. The second hypothesis was accepted. The experimental group showed more change in sex-related attitudes than the control group (t=11.91, p=0.0001). In conclusion, the level of sex-related knowledge and sex-related attitudes of middle school girls who received sex education was higher than that of the girls who did not receive sex education. According to this research, planned sex education was effective in forming accurate knowlege and appropriate attitudes related to sex. Clearly, we must carry out a well-designed step by step sex education program that is well-suited to the sex education needs and the developmental level of the students.

  • Some extensions of minimum spanning tree problem are NP-hard problem in which polynomial-time solutions for them do not exist. Because of their complexity, recently some researcher have used the genetic algorithms to solve them. In genetic algorithm approach the Prufer number is usually used to represent a tree. In this paper we discuss the problem of the Prufer number encoding method and propose an improved genetic operation. Using a numerical comparison we demonstrate the excellence of the proposed method.
