For the purpose of strengthening Dental Hygiene students' confidence and motivation in the Dental Hygiene Department and helping construct proper professionalism, survey on Dental Hygiene students' consciousness of attitude to and satisfaction of the course, career plan and occupation mind set was carried out. 530 three year students in 8 Dental Hygiene academies in Seoul and Kyonggi province were questioned. The results of the survery are as follows:. 1. Dental Hygiene students' motives consisted primarily of employment and a desire for professionalism 25% of them entered the course after one failure in the entrance examination and 17% had family members engaging in the dentistry field 84%, the largest portion, were from an academic high school. 24% had some knowledge of Dental Hygiene, which they had acquired from seniors, friends, and teachers. 2. Patient care and treatment assistance related matters were not considered important in the course. The weak points of the course turned out to be education in computers and foreign languages, but the weakest was the ability of patient care during clinical training. 53% had experiences had thought of changing their major while in the course because it didn't match their aptitude and interest. 3. As for a career after graduation, 49% worried about it Most students wanted to work at a dental hospital or general hospital, The most favored duty was coordination or reception or oral disease preventive work. They wanted to work untill they had a stable living. 68% answered they would get a job at an oral clinic and 70% said they would continue studying for self-realization. 4. Satisfaction with the major was high in students whose aptitude and interest matched the course, who had background knowledge of the major, and who. didn't think of changing the major but would continue studying resulting in statistically slight difference(p<0.001). As to satisfaction with the faculties, it was high in the students whose aptitude and interest matched the major and who didn't think about a career after graduation showing a slight difference(p<05, p<0l). As for satisfaction with clinical training, students whose aptitude and interest matched the major and who didn't consider changing the major answered positively showing a statistically slight difference(p<.001, p<.01). As to satisfaction with the course, it was high in the students who entered with aptitude and interest, who had preliminary knowledge, who didn't consider changing the major, and who didn't think about a career after graduation showing a statistically slight difference(p<.001, p<.05). 5. Occupation mind-set was positive for students who entered with interest and aptitude, who had preliminary knowledge, and who had not considered changing the major showing a statistically slight difference(P<.001). The higher the satisfaction with the major, faculty and clinical training was, the more positive the occupation mind-set was(p<.001).

This study was conducted to analyze the strengths and weaknesses of a 3-week family medicine clerkship program based on the results of an online survey taken by the students (N=127) and a structured interview with a focus group (n=10), aimed to improve the quality of the clerkship program. The online survey contained questions pertaining to goals, schedule, contents, arrangement, atmosphere, environment, evaluation, and satisfaction regarding the clerkship. The focus group interview addressed the schedule and achievements of the program. Scores were reported on a 5-point Likert scale. Most students were highly satisfied with the overall quality of the clerkship. The structured interview results showed that 97.6% of the clerkship program was executed according to the schedule. The focus group reported a perfect score of 5 points on several measures including: accomplishment of the educational goals of the family medicine clerkship, providing many chances to obtain medical histories and perform physical examinations on real patients, experience with various symptoms and diseases, positive attitudes of faculty members when teaching, notification of the guidelines for evaluation beforehand, well-constructed and effective clerkship schedule, and reflection of student feedback. However, the focus group gave low scores on: support for health accidents of students, access to patient information, enough opportunities to practice clinical skills, appropriate rest facilities for students, and fairness of clerkship evaluation process. In conclusion, the structured evaluation performed after the 3-week clerkship program motivated students and helped them ensure an efficient clerkship. This structured evaluation also suggested basic data to make the professor who is subject of the assessment. This study shows that structured assessment is an effective method which can be used to improve the quality of clerkships.

This study aimed to examine the Factor Structure of the teacher satisfaction scale (TSS) with distance education during the Covid-19 pandemic, as well as affirming the (Factorial Invariance) according to gender variable. It also aimed at identifying the degree of satisfaction according to some demographic variables of the sample. The study population consisted of all teachers in public education and faculty members in higher education in the Kingdom of Saudi Arabia. The (TSS) was applied to a random sample representing the study population consisting of (2399) respondents. The results of the study showed that the scale consists of five main factors, with a reliability value of (0.94). The scale also showed a high degree of construct validity through fit indices of the confirmatory factor analysis. The results have shown a gradual consistency of the measure's invariance that reaches the third level (Scalar-invariance) of the Measurement Invariance across the gender variable. The results also showed that the average response of the study sample on the scale reached (3.74) with a degree of satisfaction, as there are no statistically significant differences between the averages of the study sample responses with respect to the gender variable. While there were statistically significant differences in the averages with respect to the variable of the educational level in favor of the middle school and statistically significant differences in the averages attributed to the years of experience variable in favor of those whose experience is less than (5) years.

Inelastic static pushover analysis has been used in the academic-research widely for seismic analysis of structures. Nowadays, the variety pushover analysis methods have been developed, including Modal pushover, Adaptive pushover, and Cyclic pushover, in which some weaknesses of the conventional pushover method have been rectified. In the conventional pushover analysis method, the effects of cumulative growth of cracks are not considered on the reduction of strength and stiffness of RC members that occur during earthquake or cyclic loading. Therefore, the Cyclic Pushover Analysis Method (CPA) has been proposed. This method is a powerful technique for seismic evaluation of regular reinforced concrete buildings in which the first mode of them is dominant. Since the bridges have different structures than buildings, their results cannot necessarily be attributed to bridges, and more research is needed. In this study, a cyclic pushover analysis with four loading protocols (suggested by valid references) by the Opensees software was conducted for seismic evaluation of two regular reinforce concrete bridges. The modeling method was validated with the comparison of the analytical and experimental results under both cyclic and dynamic loading. The failure mode of the piers was considered in two-mode of flexural failure and also a flexural-shear failure. Along with the cyclic analysis, conventional analysis has been studied. Also, the nonlinear incremental dynamic analysis (IDA) method has been used to examine and compare the results of pushover analyses. The time history of 20 far-field earthquake records was used to conduct IDA. After analysis, the base shear vs. displacement in the middle of the deck was drawn. The obtained results show that the cyclic pushover analysis method is able to evaluate an accurate seismic behavior of the reinforced concrete piers of the bridges. Based on the results, the cyclic pushover has proper convergence with IDA. Its accuracy was much higher than the conventional pushover, in which the bridge piers failed in flexural-shear mode. But, in the flexural failure mode, the results of each two pushover methods were close approximately. Besides, the cyclic pushover method with ACI loading protocol, and ATC-24 loading protocol, can provided more accurate results for evaluating the seismic investigation of the bridges, specially if the bridge piers are failed in flexural-shear failure mode.

Objectives: Oxidative stress plays a key role in chronic and acute brain disorders and neuronal damage associated with Alzheimer disease (AD) and other neurodegeneration symptoms. The neuroprotective effects of berberine and Berberis vulgaris (barberry) root extract against apoptosis induced by hydrogen peroxide (H₂O₂) in the human SH-SY5Y cell line were studied. Methods: The methanolic extraction of barberry root was performed using a maceration procedure. Oxidative stress was induced in SH-SY5Y cells by H₂O₂, and an MTT assay was applied to evaluate the neuroprotective effects of berberine and barberry root extract. The cells were pretreated with the half maximal inhibitory concentration (IC₅₀) of each compound (including berberine, barberry root extract, and H₂O₂), and the anti-apoptotic effects of all components were investigated using RT-PCR. Results: The SH-SY5Y cell viability increased in both groups exposed to 75 and 150 ppm barberry extract compared with that in the H₂O₂-treated group. The data showed that exposing SH-SY5Y cells to 30 ppm berberine significantly increased the cell viability compared with the H₂O₂-treated group; treatment with 150 and 300 ppm berberine and H₂O₂ significantly decreased the SH-SY5Y cell viability and was associated with berberine cytotoxicity. The mRNA levels of Bax decreased significantly under treatment with berberine at 30 ppm compared with the control group. A significant increase in Bcl-2 expression was observed only after treatment with the IC₅₀ of berberine. The expression level of Bcl-2 in cells exposed to both berberine and barberry extracts was also significantly higher than that in cells exposed to H₂O₂. Conclusion: The outcomes of this study suggest that treatment of SH-SY5Y cells with barberry extract and berberine could suppress apoptosis by regulating the actions of Bcl-2 family members.

우크라이나는 1994년 12월 부다페스트양해각서를 통해서 국가의 주권과 영토보전 및 안전을 보장한다. 서명했던 러시아에 의해 크림반도의 침탈에 이어 2022년 2월 24일 제2의 무력침공을 받았다. 이 두 번째의 침공은 1년 2개월을 초과하는 장기전으로 가고 있다. 동(同)양해각서의 동반서명국인 미국을 향한 호소도 승산 없는 전쟁이 세계대전으로 확대될까 하는 우려로 효과가 없었다. 국가존폐위기를 모면할 수 있었던 것은 젤렌스키 대통령을 위시한 전 국민들의 단결된 결사항전정신 때문이었다. 이 애국적 자조정신이 미국을 위시한 서방의 자유민주주의 세계와 국제사회의 지원을 받게 하였고 그 강도는 날이 갈수록 증대되고 있다. 스스로를 지킨다는 자위(自衛)의지는 외부적 동맹이나 지원을 창출 한다는 것을 보이고 있다. 우크라이나전쟁이 한국에게 주는 교훈은 미래전의 형태로 부각되는 하이브리드전략과 군사적 수단과 비군사적 수단에 대한 동시통합능력을 포괄하는 독자적 국방력의 발전과 자강(自彊)의 의지 및 신뢰를 바탕으로 한 한미동맹 결속의 강화가 핵심이 되어야 함을 시사한다.
