PURPOSE. The aim of the present study was to evaluate if a smaller morse taper abutment has a negative effect on the fracture resistance of implant-abutment connections under oblique compressive loads compared to a conventional abutment. MATERIALS AND METHODS. Twenty morse taper conventional abutments (4.8 mm diameter) and smaller abutments (3.8 mm diameter) were tightened (20 Ncm) to their respective implants ($3.5{\times}11$ mm) and after a 10 minute interval, implant/abutment assemblies were subjected to static compressive test, performed in a universal test machine with 1 mm/min displacement, at $45^{\circ}$ inclination. The maximum deformation force was determined. Data were statistically analyzed by student t test. RESULTS. Maximum deformation force of 4.8 mm and 3.8 mm abutments was approximately 95.33 kgf and 95.25 kgf, respectively, but no fractures were noted after mechanical test. Statistical analysis demonstrated that the evaluated abutments were statistically similar (P=.230). CONCLUSION. Abutment measuring 3.8 mm in diameter (reduced) presented mechanical properties similar to 4.8 mm (conventional) abutments, enabling its clinical use as indicated.

Purpose : The objective of this research is to explore the correlation between personality and degree of job-satisfaction among nursing profession in order to provide effective guide for HR management and nursing care. Method : The research has been conducted on hundred sixty four nurses working in C university hospital in Seoul, from February 23 to March 7 of 2002, through survey. For the experimental tools, I have used Young-Hwan Kim's MMPI(1988) personality test and Slavitt's job-satisfaction test(1978) which were improved by Eun-Seuk Lee(1988). The acquired data are analyzed through SPSS program using descriptive statistical method, t-test, One way ANOVA and Pearson Correlation coefficient analysis. Results : Most survey score were within normal range of personality measurement and Masculinity-Femininity scored high compare with the rest. Overall job-satisfaction score showed fairly high level of 3.01; in the order of high score, 3.43 for reciprocal action, 3.41 for job requirement, 3.20 for autonomy, 3.15 for professional status, 2.96 for doctor-nurse relationship, 2.54 for administration and 2.38 for compensation. Analysis based of social demographics showed that the degree of paranoia depends on the age, marriage, nursing experience, education, professional status and salary. Also, marriage had significant influence on the score of hysteria, psychopathic deviation, paranoia, psychasthenia, schizophrenia and masculinity-femininity. Test score showed that, based on the general characteristic of nursing profession, job-satisfaction depends on the age and professional status. The relationship between personality and job-satisfaction showed that depression score and social introversion score have statistically significant negative correlation with job-satisfaction. Conclusion : this research revealed that depression and social introversion are characteristics identified to have significant influence over job-satisfaction of nurses, among many characteristics.

This study aimed to examine the influence of the coronavirus disease 2019 (COVID-19) pandemic on areas of Korean medical students' lives, assess concerns, and investigate the strategies they used to cope with stress due to the pandemic. An online survey with a total of 53 items on the impact of COVID-19, concerns, and coping strategies was sent to medical students, and responses were collected from April 27, 2021 to May 30, 2021. In total, 1,329 students were included in the study. Analysis was performed using the chi-square test, independent-sample t-test, and one-way analysis of variance, and the post-hoc Scheffé test or Games-Howell test was performed for multiple comparisons. The main negative impacts of the pandemic were on hobbies/leisure activities and mental health, and medical students expressed the highest levels of concern regarding restriction of movement, returning to everyday life, and risk of infection for family and friends. Female students more strongly agreed that COVID-19 had increased their depressed mood and anxiety (p<0.001 and p=0.003, respectively). Furthermore, the negative impacts of the pandemic on different areas of life significantly affected current levels of depressed mood and anxiety. To cope with pandemic-related stress, students used several strategies such as talking with family or friends (91.5%), sleeping (83.1%), exercising (72.8%), using social networking services (60.8%), drinking alcohol (37.8%), and practicing meditation/mindfulness (24.4%); the effectiveness of these strategies ranged from 3.45 to 4.19 on a 5-point Likert-type scale (1-5). The study findings suggest that COVID-19 has influenced the mental health of medical students and raised concerns in many areas of their lives. Students used various strategies to cope with the pandemic-related stress; since the effectiveness of frequently used approaches varied, it is essential to guide medical students to develop effective coping strategies.

This study is a descriptive research that provides basic data to develop customized emergency education programs for strengthening the emergency coping ability of facility and group home caregivers. Data were collected from 7.10~8.15 in 2020 in the S and G areas. A total of 236 questionnaires were included for the analysis. Data were analyzed using χ², t-test, ANOVA, and Pearson's correlation coefficients. Approximately 68.9% facilities and 50.7% group homes experienced emergencies, and there was a significant difference (χ²=8.42, p=0.004). First aid personnel were nurses (nurse aides) 55.3% facility and 42.7% of facility directors group home, showing differences (χ²=27.84, p<.001). 56.5% and 68.0% in the facility and group home, first aid care : ice pack, medication, Heimrich in the facility and 119 and guardian call, ice pack, Heimrich for the group home. First aid knowledge was determined to be significantly different between the facilities (11.60±2.09) and group homes (9.08±2.28) (t=8.39, p<0.001). Similarly, the emergency coping abilities showed a significant difference (t=8.00, p<0.001) between facilities (52.94±5.27) and group homes (47.33±4.39). In addition, a positive correlation was established between the experience of emergency situations and the emergency coping ability in the facilities. Overall, our data indicates that the emergency experience, emergency knowledge, and emergency coping abilities of the facility and group home caregivers are significantly different. We propose that emergency education tailored to the characteristics of each institution is needed.

Sertraline HCl, (1S-cis)-4-(3, 4-dichloro-phenyl)-1, 2, 3, 4-tetrahydro-N-methyl-l-naphthalenamine hydrochloride, is a potent and selective serotonin reuptake inhibitor which is used in the treatment of depression and obsessivecompulsive disorders. The purpose of the present study was to evaluate the bioequivalence of two sertraline HCl tablets, Traline tablet (Myungin Pharm. Co. Ltd.) and Zoloft$^{(R)}$ tablet (Pfizer Inc.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The in vitro release of sertraline from the two sertraline HCl formulations was tested using KP VIII Apparatus II method with various dissolution media. Twenty four healthy Korean male volunteers, $23.50{\pm}1.74$ years in age and $64.09{\pm}7.10\;kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ crossover study was employed. After a single tablet containing 50 mg as sertraline HCl was orally administered, blood samples were taken at predetermined time intervals and the concentrations of sertraline in serum were determined using an online columnswitching HPLC method with UV/Vis detection. The dissolution profiles of two formulations were similar in all tested dissolution media. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated, and computer programs (Equiv Test and K-BE Test) were utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and un-transformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, Zoloft$^{(R)}$ tablet, were 0.04, 3.26 and -1.29% for $AUC_t$, $C_{max}$, and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log0.8 to log1.25. Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Traline tablet was bioequivalent to Zoloft$^{(R)}$ tablet.
