Objective: The aims of this study were to use a 3-dimensional (3D) system to compare molar relationship assessments performed from the buccal and lingual aspects, and to measure differences in occlusal contact areas between Class II and Class I molar relationships. Methods: Study casts (232 pairs from 232 subjects, yielding a total of 380 sides) were evaluated from both the buccal and lingual aspects, so that molar relationships could be classified according to the scheme devised by Liu and Melsen. Occlusal contact areas were quantified using 3D digital models, which were generated through surface scanning of the study casts. Results: A cusp-to-central fossa relationship was observed from the lingual aspect in the majority of cases classified from the buccal aspect as Class I (89.6%) or mild Class II (86.7%). However, severe Class II cases had lingual cusp-to-mesial triangular fossa or marginal ridge relationships. Mean occlusal contact areas were similar in the Class I and mild Class II groups, while the severe Class II group had significantly lower values than either of the other 2 groups (p < 0.05). Conclusions: Buccal and lingual assessments of molar relationships were not always consistent. Occlusal contact areas were lowest for the Class II-severe group, which seems to have the worst molar relationships - especially as seen from the lingual aspect.

Purpose: The purpose of this study was to examine the effects on knowledge and performance in clinical nurses who participated in education on nursing recording focusing on the legal aspects. Method: The participants were working in medical departments in one hospital. There were 32 nurses in the experimental group and 25 in the control group. Pre-test was conducted on the two groups before education, and, in order to examine the effects of education, a post-test was conducted after three weeks. For the experimental group, the education on nursing recording focusing on legal aspects was provided as a lecture-led one-to-one training. Results: Significant differences were found between the experimental and control groups in knowledge (F=15.728, p<.001), and performance (F=42.454, p<.001). Conclusions: The results of this study indicate that education on nurse recording enhances the knowledge and performance of the nurses. Thus education on nurse recording focusing on legal aspects should be required in the area of nursing science.

Clinicians often meet the growing patient who is not treated with fixed prosthesis until alveolar bone growth is completed. When both esthetic and function needs are important, and if proper donor tooth is present, the application of autotransplantation may be better treatment option than space maintainer. Although prognosis of autotransplantation is not always favorable, it depends on the treatment design which is based on the ability of case selection and consideration. This report will present the clinical cases of autotransplantation in growing patient, and discuss about several clinical aspects of autotransplantation.

Gene therapy is becoming a very promising and feasible medical intervention as the understanding of human diseases extends to their molecular levels. Since the first US Food and Drug Administration (FDA)-approved human gene therapy protocol was approved in 1990, over 300 human clinical trial protocols had been approved worldwide so far. Even though some of the domestic gene therapy clinical trials also proved promising and more are awaiting, it should be emphasized that many safety aspects as well as effectiveness aspects should be considered during the development process. Moreover, there seems to be less restricted guidelines from the National Control Authority (NCA) in initiating human clinical trials. This article is intended to suggest some basis and points to consider in the development and evaluation of gene therapy products including antisense oligonucleotides pharmaceuticals.

The evolution of X-ray computed tomography (CT) has been based on the discovery of X-rays, the inception of the Radon transform, and the development of X-ray digital data acquisition systems and computer technology. Unlike conventional X-ray imaging (general radiography), CT reconstructs cross-sectional anatomical images of the internal structures according to X-ray attenuation coefficients (approximate tissue density) for almost every region in the body. This article reviews the essential physical principles and technical aspects of the CT scanner, including several notable evolutions in CT technology that resulted in the emergence of helical, multidetector, cone beam, portable, dual-energy, and phase-contrast CT, in integrated imaging modalities, such as positron-emission-tomography-CT and single-photon-emission-computed-tomography-CT, and in clinical applications, including image acquisition parameters, CT angiography, image adjustment, versatile image visualizations, volumetric/surface rendering on a computer workstation, radiation treatment planning, and target localization in radiotherapy. The understanding of CT characteristics will provide more effective and accurate patient care in the fields of diagnostics and radiotherapy, and can lead to the improvement of image quality and the optimization of exposure doses.

Purpose: This study aimed to identify the types of perception toward non-face-to-face clinical practice and to characterize the types of students who experienced online clinical practice during the coronavirus disease 2019 (COVID-19) pandemic. Methods: Q-methodology was used in this study, and 270 Q populations were formed based on in-depth interviews with 10 nursing students who had experienced non-face-to-face clinical practice, as well as related literature. Interviews were performed from August 1 to 31, 2022. A total of 42 Q samples were extracted, and Q sorting was performed on 33 nursing students who had experienced non-face-to-face clinical practice. A Q factor analysis was performed using the PC-QUANL program. Results: The nursing students' perceptions of non-face-to-face clinical practice were classified into the following five types: "future professional competency-focused type," "realistic convenience priority type," "task burden awareness type," "negative critic type," and "limited experience dissatisfaction type." Conclusion: This study revealed non-face-to-face clinical practice's positive and negative aspects in nursing education. Moreover, it identified the aspects of clinical practice that cannot be replaced by non-face-to-face clinical practice and the elements of non-face-to-face practice that can complement clinical practice. These findings can be used as fundamental data to establish a stable and efficient system for improving the quality of clinical practice in the post-COVID-19 era and to implement effective non-face-to-face clinical practice according to student types.

This study of nurse educator's attitudes which found aspects of professional nursing was carried out from September 10 to 30, 1977. Subjects were 205 respondents from a total population of 314 nurse educators from the level of instructors to professors in all the diploma (post high school 3 year), professional junior college (3 year level) and university (4 year) nursing schools in Korea. Specific objectives were to determine their attitudes about the 1. social position of nursing as a profession, 2. nurses attitudes towards their word, 3. factors influencing the development of nursing, 4. the future of nursing, 5. nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits. The instrument used was a questionnaire developed from consultations with nursing educators and sociologists, and based on earlier. worts by Burke (1976), Mason (1974) and Hong 1969. Data were analysis by computer using one-way analysis. Statistically significant findings included the following; 1. Responses were positive toward all seven aspects of professional nursing. 2. Compared to diploma nursing school staff whose responses were positive, professional and university school faculty response toward the social position of nursing were neutral. 3. Faculty with clinical experience of 10 to 19 years were most positive in their responses about nurses' attitudes towards their work. In all three types of schools, in comparison to professors, associate professors' responses were more positive about nurses' attitudes toward their work. Faculty with longer clinical experience expressed high agreement with statements about factors which influence the development of nursing. Without any differences between school, all faculty had positive attitudes towards the future of nursing, the younger the staff member, the more positive were the responses. 4. faculty in diploma schools and those with 10 to 19 years clinical experience expressed high agreement with statement about nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits.

Background : Mycoplasma pneumonia (M. pneumonia) is a major cause of atypical pneumonia, and its incidence is predominantly at childhood and early adulthood. In contrast, the incidence of adult patients with M. pneumonia has been known to be low. Furthermore the clinical aspects of M. pneumonia are different from those of community acquired pneumonia. Thus, we evaluated the clinical aspects of M. pneumonia in the adult patients. Method : Mycoplasma antibody and cold agglutination tests were performed in patients with clinically suspected pneumonia who had abnormal infiltrations on chest P-A. The 12 patients with pneumonia, who fulfilled entry criteria of more than 1:64 of cold agglutination titer and 1:40 of mycoplasma antibody titer or four-fold increase of mycoplasma antibody titer during one week, were analyzed in terms of clinical aspects. Results : 1) Twelve patients, male 3 and female 9, were included in this study. The peak incidence was teenager. 2) M. pneumonia occured perennially, but predominantly between June to October in eight patients. 3) The main symptoms were fever, coughing, sputum. 4) The main patterns of chest P-A were bronchopneumoina in 8 cases, and involved lesion were nearly both lower lobe. Conclusion : The clinical aspects with Mycoplasma pneumonia in adult patients were different from those of community acquired pneumonia.

Purpose: The purpose of this study was to understand the positioning which was perceived by nursing students from their clinical practice experiences. Methods: The data were 80 narratives of practice experience written by 20 nursing students. Using qualitative contents analysis, nursing students' reflective narratives were analyzed in the aspects of the positioning which including personal characteristics, designated social role, and ethical order. Results: In personal characteristics, nursing students positioned themselves as they had vague fear and cold feet about the physical and personal environment of the clinical setting. In the aspects of the designated social role, they positioned themselves to learn more knowledge and skills of the nursing, to put effort in maintaining good relationship with their patients and other nurses, and to evaluate the nurses on their job performances and professional attitudes. In ethical order, nursing students positioned themselves as a person who worries about their work as a future professional nurse. Conclusion: The result of this study can be used to better understand nursing students and application of the nursing students' narratives in the clinical practice education, and to facilitate positive outcomes and transitions from nursing students to nurses.

With recent emphasis on evidence based medicine, clinical practice guidelines are seen as a potential mechanism by which unify various managerial and professional approaches to improving the quality of care. The development process of guidelines has been the subject of much research. and it is need translating the medical evidence of research into a clinical practice guidelines. the gathered evidence needs to be interpreted into a clinical, public health, policy, or payment context. The term 'clinical practice guidelines' can evoke a diverse range of responses from healthcare personnel. Clinical practice guidelines are increasingly used in patient management but some clinicians are not familiar with their origin or appropriate applications. Understanding the limitations as well as benefits of CPG could enable clinicians to have clearer view of the place of guidelines in every practice. In the context of increasing complaints and litigation in healthcare, the legal implications of clinical practice guidelines are of increasing importance. Clinical practice guidelines could, in theory, influence the manner in which the courts establish negligence by suggesting the doctor breached the duty of care by failing to provide the required standard of medical care. In several studies, the CPGs were relevent to and played a pivotal role in the proof of negligence. Much depends on the quality of guidelines and the tools developed and the authoritativeness of a guideline. Recently, there are several opinions the court also should review the validity and reliability of expert testimony including medical evidence. and widespread use of guidelines in malpractice lawsuit could lead the physicians to greater compliance with guidelines in the long term. In conclusion, Health care reformers, physicians as well as guidelines developers should understand that guidelines have both medical and legal aspects as a double-edges sword. so clinicians, legal representatives and decision-makers should not defer unduly to guidelines.
