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.

As hyperboloidal cooling towers (HCTs) growing larger and slender, they become more sensitive to gust wind. To improve the dynamic properties of HCTs and to improve the wind resistance capability, stiffening rings have been studied and applied. Although there have been some findings, the influence mechanism of stiffening rings on the dynamic properties is still not fully understood. Based on some fundamental perceptions on the dynamic properties of HCTs and free ring structures, a concept named "participation degree" of stiffening rings was proposed and the influence mechanism on the dynamic properties was illustrated. The "participation degree" is determined by the modal deform amplitude and latitude wave number of stiffening rings. Larger modal deform amplitude and more latitude waves can both result in higher participation degree and more improvement to eigenfrequencies. Also, this concept can explain and associate the pre-existing independent findings.

Purpose: This research was conducted to identify major factors that influence competency for nursing students in basic nursing skills. Method: Data were collected by questionnaires from 290 first year students in one college of nursing. The instrument tools included motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, level of active participation in fundamentals of nursing, number of times to use open Lab, Lab class satisfaction, self-efficacy, self-evaluation and student attitude. Results: There was no significant correlation between competency in basic nursing skills and motivation for admission to nursing, concern about fundamentals of nursing, perceived importance of fundamentals of nursing, or number of times to use open Lab. Competency in basic nursing skill in these students showed a significantly positive correlation to Lab class satisfaction, self-efficacy, self-evaluation, student attitude and level of active participation in fundamentals of nursing. The major factors that influenced competency in basic nursing skills for nursing students were student attitude, self-efficacy and number of times to use open Lab. These factors explained 15.5% of the variance in competency. Conclusion: Basic nursing skill practice education programs should be developed to improve self-efficacy and active participation.

This study describes the hypertensive patients characteristics associated with the health incentive point program, and develops and analyzes a simple predictive model of participation in the program. Based on the Incheon Chronic Disease Management System(iCDMS), a model program of community partnership for hypertensive or diabetic patients detection and follow-up since 2005 in Incheon metropolitan city, a cross-sectional design was used in this study. An effective 10.844 adults sample was divided into groups according to participation in the health incentive point program and continuing treatment, and individual and health characteristics among groups were compared. Furthermore, the predictors associated with participation in the program were identified by the logistic regression analysis. After the health incentive point program in iCDMS was introduced, the number of hypertensive patients participation in the program increased 23.9 times which is vastly high given the various programs were provided. There were statistically significant differences among the groups: age(p=0.000), treatment compliance(p=0.000), and blood pressure control at the last measurement(p=0.000), in particular, between participation group(GroupI, n=246) and non-participation group(GroupIII, n=10,408). Furthermore, age over 60 years(OR: 0.33), treatment compliance(OR: 3.49~3.78) and blood pressure controls(OR: 2.13~2.30) were statistically significant predictors associated with participation in the program, based on the logistic regression analysis with GroupI and GroupIII. To increase participation in the health incentive point program, variables such as age, treatment compliance and blood pressure controls are more concerned. And, high-risk patients and family members need targeted health incentive programs.

Local governments in Korea are involved in three types of online shopping sites : 'direct operation', 'outsourced operation', and 'sales agency.' They are different in terms of the site operator and the charging mechanism among a local government, the site operator, and local producers. This study analyzes their differences in site traffic, local producers' participation, promotion, and partnership. The results from the investigation of 72 shopping sites are the following. First, shopping sites of the 'direct operation' type and the 'outsourced operation' type show significantly higher participation of local producers. Second, the 'marketing agency' type has significantly higher number of promotional activities than the 'oursourced type' which has significantly higher number than the 'direct operation' type. Third, the number of partnerships in the 'marketing agency' type is the highest. The 'direct operation' type is the second and significantly higher than the 'outsourced type.' On the basis of the analysis results, this paper suggests an incubation ecosystem model as a better way of involvement by local governments in online shopping sites.

It has been 2 years since the implementation of the separation of prescription and drug dispensing policy. This study analyzes the effects of the policy on the job contents and personnel structure of hospital pharmacy. The main purposes of the analysis are to determine if the policy has causes the increase of professional activities of pharmacists in hospital and to investigate whether the hospital pharmacy is equipped with enough manpower to provide high quality pharmaceutical service as intended by the policy. The level of professionality of pharmacists' activities is measured by the number of activities of direct involvement in inpatient care such as participation in patient rounding, medication consultation, the number of hospital committee the pharmacists involved and the number of continuous education pharmacists took. The adequacy of personnel structure to provide high quality pharmaceutical care is measured by the level of compliance to the governmental standard of hospital pharmacy personnel. In order to collect the data, surveys were performed for two periods: year 1999 (before the implementation of the policy) and year 2001 (after the implementation of the policy). The results show that the pharmacists' participation in inpatient rounding decreased and that the inpatient medication history management activities, operation of ward pharmacy, participation in hospital committee increased. In personnel structure, the average number of pharmacist per hospital decreased and the number of prescription processing per pharmacist increased. Based on the results this study concludes that the professional activities of hospital pharmacists has increased a little and there were structural changes in hospital pharmacy service activities to increase the professionalism in providing care. However, the pharmacy departments were understaffed hampering the strive to increase the provision of professional pharmaceutical service in hospitals.

The development and use of computer mediated communications (CMC) as a tool for teaching and learning English has grown considerably in recent years. The purpose of this study is to investigate factors related to learners' participation, achievement, and satisfaction in EFL classes using web-based bulletin boards. The total number of 77 university students participated in this study. Three domains and eight independent variables investigated in this study were a learner-related domain (attitudes toward CMC, intrinsic motivation, extrinsic motivation, attitudes toward writing), an interaction-related domain (student-student interaction, teacher-student interaction), and an environmental domain (physical support and design of the web site). In order to determine interrelation of variables correlation analysis and multiple regression analysis were used. The results of this study showed that the factors predicting a learner's participation were instrumental motivation, attitudes toward writing, and teacher-student interaction. The factors explaining a learner's achievement were learner's participation and attitudes toward writing, and the factors predicting a learner's satisfaction were integrative motivation, student-student interaction, teacher-student interaction, physical support and learner's participation.

This paper presents new algorithms equivalencing large-scale power systems. Generators are identified to the coherent groups according to the relation factors, which represent the relative coupling degree between the generators. While the groups are identified, participation numbers, which are the measure of the relative participation of the generators in the group, are obtained. All generators and controllers in the group are weighted by participation numbers and aggregated to construct a dynamic equivalent. The proposed algorithms are applied to a 272-machine Korea Electric Power Corporation (KEPCO)'s system. The enclosed results indicate the accuracy and usefulness of the algorithms.
