We examine whether the observational stand-off distance ratios of CMEs and their associated ICMEs could be explained by theoretical model or not. For this, we select 16 CME-ICME pairs from September 2009 to October 2012 with the following conditions: (1) limb CMEs by SOHO and their associated ICMEs by twin STEREO spacecraft and vice versa when both spacecraft were roughly in quadrature; (2) the faint structure ahead of a limb CME is well identified; and (3) its associated ICME clearly has a sheath structure. We determine the observational stand-off distance ratios of the CMEs by using brightness profiles from LASCO-C2 (or SECCHI-COR2) observations and those of the ICMEs by solar wind data from STEREO-IMPACT/PLASTIC (or OMNI database) observations. We also determine the theoretical stand-off distance ratios of the CME-ICME pairs using semi-empirical relationship based on the bow shock theory. We find the following results. (1) Observational CME stand-off distance ratio decreases with increasing Mach number at the Mach numbers between 2 and 6. This tendency is consistent with the results from the semi-empirical relationship. (2) The observational stand-off distance ratios of several ICMEs can be explained by the relationship.

A self directed learning(SDL) has been identified as an important ability for medical graduates. The purpose of this study was 1) to measure the SDLR of medical students, 2) to compare the relationship among the student perceptions of assessment, preference of instructional methods with SDLR. This study was conducted in 2006 at A University College of Medicine. The instrument applied to this study was SDLR. Korean version of Guglielmino's SDLR for Adults. The $SPSSwin^{(R)}$ program was used to analyze the data and statistics such as correlation. F-test, and Chi square test. Firstly. the mean scores of the SDLR of first, second. fourth year were 114.8, 107.9 and 106.2. This results showed a significant relationship among years (p<.001). Secondly the relationship between the student perceptions of assessment and SDLR was insignificant. The SDLR high scores students had a tendency to favorite "Discussion" and "Bedside teaching". This study found out the problems of medical education to enhance self directed learning ability for medical students. Further study is needed so that suitable instructional methods for medical students can be conducted in curriculum.

This study attempts a comparison between AHP(Analytic Hierarchy Process) in which the importance weight is structured by individual subjective values and regression model with importance weight based on statistical theory in determining the importance weight of casual model. The casual model is designed by for students' satisfaction with university, and SERVQUAL modeling methodology is applied to derive factors affecting students' satisfaction with university. By comparison of importance weights for regression model and AHP, the following characteristics are observed. 1) the lower the degree of satisfaction of the factor, the higher the importance weight of AHP, 2) the importance weight of AHP has tendency to decrease as the standard deviation(or p-value) increases. degree of decreases. the second sampling is conducted to double-check the above observations. This study empirically checks that the importance weight of AHP has a relationship with the mean and standard deviation(or p-value) of independence variables, but can not reveal how exactly the relationship is. Further research is needed to clarify the relationship with long-term perspective.

Purpose: This study aimed to determine the moderating effect of self-esteem on the perception of death and the meaning of life among hospital nurses. Methods: The participants were 167 nurses working in two tertiary general hospitals located in city B. Data were collected from September 8 to 21, 2022. SPSS/WIN 29.0 was used for analysis along with t-test, ANOVA, Pearson correlation coefficients, and hierarchical multiple regression. Results: The study showed that the meaning of life was significantly correlated with the perception of death (r=.34, p<.001) and self-esteem (r=.31, p<.001). Self-esteem significantly moderated the relationship between the perception of death and the meaning of life (F=16.00, p<.001). Conclusion: Self-esteem may moderate the relationship between the two factors. This means that nurses with higher self-esteem have a greater tendency for their perception of death to positively impact their meaning of life. Therefore, for hospital nurses to discover the meaning of life, it is necessary to develop and apply a self-esteem enhancement program specialized for each clinical career.

Objective: The purpose of this study is to investigate whether emotionality at age three predicts early school-age media overdependence and to examine the potential mediating role of internalizing behavior problems in children. Methods: This study employed data from the 4th and 10th waves of the Panel Study of Korea Children, comprising a sample of 1,270 children. Assessments of emotionality (4th wave), media overdependence (10th wave), and internalizing behavior problems (10th wave) were conducted. Data analysis utilized SPSS and the Process Macro. Results: At age 3, heightened emotionality was found to directly contribute to an increased tendency for media overdependence in early school age. Internalizing behavior problems played a significant mediating role in the relationship between emotionality and media overdependence. Conclusion/Implications: This study validated a significant longitudinal connection between emotionality and the inclination to excessively rely on media, highlighting the role of internalization behavior problems in this relationship. It is essential to provide focused attention, especially to children displaying heightened emotionality in early childhood, in order to proactively prevent internalization behavior problems and the undue dependence on media.

Today the number of economically independent women are increasing in Korea, they have a tendency to pay more attention to their appearance in their social life. Female university students show a high tendency of that kind, especially when they prepare for their job interviews. They purchase beauty products, visit beauty salons and skin care centers to improve their looks. Above all, their interest in nail art is amazingly increasing for maintaining their self-image. This study thus aims at surveying the relationship between college woman's life style and their interest in nail care, by analysing life styles of college women pursuing up-to-date style. The results show that an 'egoistic' type has a high interest in and a high frequency of using a nail care center, and 'egoistic' type's demand for the nail service is equal to or quite higher than 'appearance-oriented' type's. That means that the 'egoistic' type seems to pay much attention to how they look, because they think their neat appearance help to accomplish their ego.

Objectives : Self-esteem is a necessary inner factor for the korean medicine undergraduate, who will perform a various treatment relationship as a future health care provider. Writing is closely related with improving self-esteem by providing insight towards oneself. Methods : The level of self-esteem and current state of writing among 251 undergraduates studying korean medicine in Dongshin University were looked into through a structural survey. Results : Self-esteem score was 3.12 on a scale of 4 which was relatively high, but they showed defensive self-esteem tendency. Meanwhile writing variables appeared to be more influential to the self-esteem of undergraduates than personal characteristics. Also among writing variables, emotional writing and writing 2 to 3 times or more a month was related to high self-esteem which defensive self-esteem tendency is low. Majority of the undergraduates, however, turned out to be writing essay and writing 2 to 3 times a month. Conclusions : The following result suggests the need of writing classes as well as writing involved in emotion for self-esteem and improve medical communication in the curriculum of korean medical college.

Author has made an experiment on absolute speeds of 18 screenfilm combinations that have been on sale in Korea, with various beam qualities. At this time, the beam qualities were 60kVp with the ANSI extremity phantom, 80kVp with the ANSI chest phantom and 85kVp with 20 mm aluminium filter under scatter free condition. The obtained results were as follows; 1. When three independent measurements were performed, the percent standard deviations of mAs quantities of 1.0 + fog were decreased by the hardening of the beam quality, and the decreasing tendency was somewhat great in the blue systems. 2. Generally, the increasing tendency of absolute speeds was distinct by the hardening of the beam quality in the green systems. Conclusively, the green systems were more strongly dependent upon the beam quality rather than the blue systems. Therefore, the relative speed of green systems to blue systems were great under the same condition. 3. Differences in the green systems were kept almost constant even though the beam qualities were changed. 4. They were shown the mutual relationship of absolute speed and relative speed rather than independent.

The purpose of this study was to compare the kinematic and kinetic parameters of lower extremity joints between novice and experienced sports aerobic dancers during two heights of depth jumps. Four male dancers were participated in this study and they performed 40cm and 60cm height depth jump three times, respectively. Four ProReflex MCU cameras (100frame/sec) and a Kistler force plate (1000Hz) were used for data collection. The results indicated that the duration of contact phase of experienced group was shorter than that of novice group regardless of jump height. For minimum angle of hip, knee, and ankle joints, the novice group had tendency to decrease the angle but the experienced group had increased the joint angle with jump height. There was no difference of total ground reaction force between the groups but the reaction force had tendency to increase with jump height. Thus, this study implied that repetition of jump and landing may induce joint related injury and further study such as. EMG analysis of lower extremity can be needed to verify the relationship between injury and ground reaction force.
