  • This study investigated the use of e-journals by health researchers in the Nigerian Institute of Medical Research (NIMR). A descriptive survey method was adopted for the study and a questionnaire was used for data collection. The study population was comprised of fifty-four (54) respondents who are health researchers in the institute. The data collected were presented and analyzed using tables, frequency distribution, simple percentages, and charts. The result of the study revealed that all the respondents are aware of the availability of e-journals and attest to making use of them. The study revealed that electronic journals were mostly used for the purpose of conducting research work and the PDF format was preferred for downloading e-journals. However, it was observed that low Internet connectivity and intermittent electricity supply constitute a major obstacle to the use of e-journals. The study, therefore, recommended that the institute's management invest more resources on network connectivity, particularly its bandwidth, and ensure reliable power supply.

  • This study was trying to find the differences of the levels of e-commerce system satisfaction and a relationship between system satisfactions and behavioral intention to use e-commerce system continuously. Based on the previous studies, we identified the factors of system satisfaction that were consist of system readiness, accuracy, content, ease of use, timeliness and IT Support. The system satisfaction levels of martial status and the training status of hospitals had significant differences. In martial status, un-married managers had higher levels of ease of use and timeliness than the married. In this result, we might consider an age effect for younger persons are more likely to use IT and have more satisfaction perceptions. Rather than training hospitals, non-training hospitals had higher level of ease of use and IT support, which could be interpreted as e-commerce systems of training hospitals might not match their own managerial purposes and need an improvement of their system functionalities. This study also identified that the factors of system satisfaction has a relationship with behavioral intentions. Except accuracy and IT support of all six system satisfaction factors, four factors were significantly correlated with system usage intentions in their e - commerce works.

  • Papillary thyroid carcinoma (PTC) is the most common thyroid cancer, accounting for 95% or more of malignancies in Korea. Recently, many thyroid cancers have been detected owing to the widespread use of ultrasonography in health surveillance. The objective of this study was to evaluate the association of known prognostic factors with the $BRAF^{V600E}$ mutation and its association features in Korean patients with papillary thyroid carcinomas. The $BRAF^{V600E}$ mutation was detected in 69.1% (256 of 370) of PTC cases. In univariate analysis, the $BRAF^{V600E}$ mutation was significantly associated with tumor size (p < 0.05) and sex. However, it was not significantly associated with other established risk factors, such as age, extrathyroidal extension, and lymph node metastasis. This finding supports the idea that the BRAF mutation plays a role in the early stage of PTC development. This relationship deserves further investigation to clarify whether $BRAF^{V600E}$ is a useful risk factor or prognostic marker for PTC.

  • Epstein Barr virus (EBV)-encoded nuclear antigen-1 (EBNA1) plays a pivotal in an EBV episome replication and persistence. Despite considerable attempts, there are no EBV drugs or vaccines. We attempted to eradicate EBV episomes by targeting EBNA1 using the transcription activator-like effector nucleases (TALEN) (E1TN). E1TN-mediated transient knockout (KO) of EBNA1 reduced EBNA1 expression, and caused significant loss of EBV genomes and progressive death of EBV-infected cells. Furthermore, when a mixture of EBV-infected Burkitt's lymphoma (BL) cells and EBV-negative BL cells was targeted by E1TN, EBV-negative cells were counter-selected while most EBV-infected cells died, further substantiating that EBNA1 KO caused selective death of EBV-infected cells. TALEN-mediated transient targeting of EBNA1 attenuated the growth of EBV-infected cells, implicating a possible therapeutic application of E1TN for EBV-associated disorders.

  • I got the following conclusion that analyzes the dental health recognition, attitude and the action of the students who major in health section executing questionnaire about dental health behaviors from March 3 through 26 with health-related university students in some area in order to arrange the fundamental data that manage their mouth health rationally by using the investigation and comparison by sex and department in dental health teaching. The results obtained were as follows : 1. A large number of students recognized dental health as an important problem, but they believed that the level of their knowledges on dental health was not so high and female students were more negative than male students with regards to their own dental health condition. 2. 49.8% of the students know about tap water fluoridation program control business and 60.7% agreed and boy's approval rate was higher than girl's. But 42.2% of the not-related buccal department's students have a reservation about tap water fluoridation program control business. 3. Average brushing number of the boy is 51.0% 2 times a day according to sex, A girl appeared highest by 48.3% 3 times a day and there was statistically significantly different according to (pE0.01). there wasn't statistically significantly different according to department. Also, the period of the brushing was the most right after a breakfast, in the order of before sleep and after dinner. 4. Whether they go to the dentist's or not, 90.8% of them say 'yes', the result showed statistically significant difference according to sex (pE0.01), but It didn't show statistically significant difference according to department. Also, the purpose for visiting the dentist's office lately was the most caries treatment. and there was statistically significantly different according to sex (pE0.01), but there was not statistically significantly different according to department. 5. Oral health education-related subject approval's rate when the education course open is 65.0% there was statistically significantly different according to department (pE0.01).

  • The purpose of this study was to examine the health segment of the 7th national physical education curriculum in an effort to grasp the state of oral health education in the school curriculum. And it's also meant to investigate the relationship between oral health education and the oral health awareness of some high schoolers to check into any possible problems with oral health education as part of health education. The subjects in this study were 240 students from two different girls' high schools in Seoul, on whom a survey was conducted to find out their oral health knowledge, behavior and awareness. And the health category of the current P.E. curriculum announced by the Ministry of Education was analyzed. The findings of the study were as follows: Oral health education provided by the high schools as part of health education in P.E. class wasn't linked to P.E. theories and practice. The weight of oral health education was extremely small in the health segment, and there was no sequence, continuity and integration among the content systems of oral health education for different grades. When some high schoolers were investigated, they weren't properly oral health conscious, though it was very important for students to receive oral health education to prevent and manage dental diseases. And they didn't consequently take care of their own oral health. Future research efforts should be channeled from diverse angles into developing oral health education curriculums to bolster school oral health education to improve national oral health.

  • 확대촬영은 일반촬영뿐 아니라 미세골촬영, 유방촬영 및 다른 진단 영역에서 널리 사용되고 있다. 유한한 X선 초점의 크기로 인해 확대촬영은 분해능, 노이즈, 대조도 등 영상 시스템 전체에 영향을 미친다. 본 연구의 목적은 유효검출양자효율(effective detective quantum efficiency, eDQE)을 이용하여 영상시스템에 있어서 확대도와 초점크기의 영향을 알아보고자 함이다. 전체적인 영상 시스템 특성을 반영하는 eDQE는 초점에 의한 흐림 현상, 확대, 산란 그리고 격자 반응 등의 영향을 고려한다. 본 실험에서는 Food and Drug Administration (FDA)에서 고안된 흉부 팬텀을 사용하여 실제 가슴 촬영조건에서 측정된 유효변조전달함수(effective modulation transfer function, eMTF), 유효잡음력스펙트럼(effective noise power spectrum, eNPS), 산란율(scatter fraction, SF) 및 투과율(transmission fraction, TF)을 통해 eDQE 값을 도출하였다. 연구 결과를 통해 살펴보면 소초점을 사용했을 경우, eMTF의 값이 10%일 때의 공간주파수는 확대도가 1.2, 1.4, 1.6, 1.8, 2.0일때 각각 2.76, 2.21, 1.78, 1.49 그리고 1.26 lp/mm이었다. 대초점을 사용했을 경우, MTF의 값이 10%일 때의 공간주파수는 확대도가 1.2, 1.4, 1.6, 1.8, 2.0일 때 각각 2.21, 1.66, 1.25, 0.93 그리고 0.73 lp/mm이었다. 확대도가 증가할수록 eMTF 값이 떨어지고, 소초점을 사용했을 때가 대초점을 사용했을 때보다 eMTF가 전체적으로 높다는 것을 확인할 수 있었다. 초점의 크기에 따른 zero frequency에서의 eDQE 값의 변화는 크게 보이지 않았다. 그러나 대초점을 사용했을 경우, 소초점을 사용했을 때보다 저 주파수에서 고 주파수로 갈수록 eDQE가 급격하게 감소하는 것을 확인할 수 있었다. 일반적으로 확대촬영은 작은 병변을 확대시키고 낮은 유효잡음과 air-gap에 의한 산란선의 감소로 인해 대조도를 증가시킨다. 이로 인해 크기가 작은 병변을 고대조도로 확대시킴으로써 진단율을 높일 수 있다. 그러나 초점 크기로 인한 흐림 현상이 확대도에 따라 공간 분해능에 더 큰 영향을 미친다. 이러한 결과를 바탕으로, 디지털 일반촬영 시스템에서의 확대촬영을 시행하기 위한 적절한 초점크기와 확대도가 확립되어야 한다.

  • The inhibitory effect of the food processing agent on growth of Escherichia coli O157:H7, Salmonella Enteritidis, and Listeria monocytogenes was performed with organic acid, and combination of citric acid, acetic acid, propionic acid and vanillic acid. The minimun inhibitory concentration(MIC) of propionic acid was 5,000 ppm in E. coli O157:H7, 2,500 ppm in Salmonella Enteritidis and Listeria monocytogenes. MIC of citric acid was 10,000 ppm in E. coli O157:H7 and Salmonella Enteritidis, 2,500 ppm in Listeria monocytogenes. MIC of acetic acid was 2,500ppm, while in vanillic acid was 5,000 ppm in Escherichia coli O157:H7, Salmonella Enteritidis, and Listeria monocytogenes. MIC of combined organc acid in E. coli O157:H7 were 2,500ppm in PC, 1,250 ppm in PA, PV, CA, CV and AV. MIC of combined organc acid in Salmonella Enteritidis were 2,500 ppm in PC, PA, PV, CA, and CV, 1,250 ppm in AV. MIC of combined organc acid in Listeria monocytogenes were 1,250 ppm in all treatment group. MIC of combined treatment of three organc acid in E. coli O157:H7, S. Enteritidis and L. monocytogenes were 1,250 ppm in PCA, PCV, PAV and CAV. The inhibitory effect of organc acid in E. coli O157:H7, S. Enteritidis and L. monocytogenes could be confirmed from the result of this experiment. Therefore, it was expected that the food process would increase or maintain by using organic acid.

  • Background: Smoking in adolescence leads to an intensified addiction to nicotine when physical and mental growth has not yet been completed. With the advent of e-cigarettes, the rate of e-cigarette use among Korean adolescents has been steadily increasing. To date, studies on e-cigarettes and oral health, especially on the relationship between smoking styles and oral health in adolescents, are limited. Therefore, this study aimed to identify the risk factors for oral health problems caused by the repeated use of conventional cigarettes and e-cigarettes. Methods: This explanatory research study compared the adolescents' experiences of periodontal disease symptoms according to smoking type through a secondary analysis of the original data from the 15th Adolescent Health Behavior Survey (2019). Cross-analysis was performed to compare the smoking patterns according to the adolescents' general characteristics. Finally, a binary logistic regression analysis was performed to determine how smoking characteristics affect the adolescents' experience of periodontal disease symptoms. Results: In terms of patients' general characteristics, significant differences were observed in sex, school level, grades, household economic status, type of residence, and father's education level between adolescents who smoked conventional cigarettes alone and those who smoked both conventional cigarettes and e-cigarettes (p<0.05). After checking the factors affecting the smoking pattern and the experience of periodontal disease symptoms in adolescents, it was found that the duplicate smoking group was more likely to experience periodontal disease symptoms (odds ratio, 1.20) than the group that smoked conventional cigarettes alone (p<0.05). Conclusion: Duplicate smokers experienced more symptoms of periodontal disease than those who smoked cigarettes alone. Based on the findings of this study, smoking cessation counseling according to the smoking type and differentiated education for oral health promotion should be provided.
