Objective: The purpose of this study is to use logistic regression and decision tree analysis to identify the factors that affect the success or failurein the national physical therapy examination; and to build and compare predictive models. Design: Secondary data analysis study Methods: We analyzed 76,727 subjects from the physical therapy national examination data provided by the Korea Health Personnel Licensing Examination Institute. The target variable was pass or fail, and the input variables were gender, age, graduation status, and examination area. Frequency analysis, chi-square test, binary logistic regression, and decision tree analysis were performed on the data. Results: In the logistic regression analysis, subjects in their 20s (Odds ratio, OR=1, reference), expected to graduate (OR=13.616, p<0.001) and from the examination area of Jeju-do (OR=3.135, p<0.001), had a high probability of passing. In the decision tree, the predictive factors for passing result had the greatest influence in the order of graduation status (x²=12366.843, p<0.001) and examination area (x²=312.446, p<0.001). Logistic regression analysis showed a specificity of 39.6% and sensitivity of 95.5%; while decision tree analysis showed a specificity of 45.8% and sensitivity of 94.7%. In classification accuracy, logistic regression and decision tree analysis showed 87.6% and 88.0% prediction, respectively. Conclusions: Both logistic regression and decision tree analysis were adequate to explain the predictive model. Additionally, whether actual test takers passed the national physical therapy examination could be determined, by applying the constructed prediction model and prediction rate.

Formaldehyde use is associated with serious health risks, which can affect medical personnel and technicians. Therefore, we investigated the efficacy of an alternative fixative, with respect to two types of formalin fixatives, by hematoxylin and eosin (H&E) staining, periodic acid Schiff (PAS) staining, immunohistochemical (IHC) staining, and RNA extraction. For H&E staining, the circular nucleus was stained dark blue by the basic dye hematoxylin and the cytoplasm was stained red by the acid dye eosin in all three fixative samples. No difference was found in the Duksan General Science (DGS), Sigma-Aldrich, and Core-Fix fixative samples (Corebiotech) used to fix kidney tissue, after PAS staining. IHC staining showed that CD4 was significantly increased in the lippolysaccharide (LPS)-treated group compared to the control group (vehicle), confirming the changes in specific molecules. The quantity and quality of RNA from tissues fixed in the three types of fixatives were evaluated. The average concentration of RNA was 106 ng/µL and average purity at A 260/280 ratio was 1.7~2.0, regardless of fixative used. For quality of protein, glyceraldehyde 3-phosphate dehydrogenase (GAPDH) protein was confirmed by Western blotting. In conclusion, Core-Fix can be used as a fixative for pathological tissues, in histological and molecular diagnoses.

Objectives: This study aimed to investigate the perceptions regarding oral muscle strength training for elder people among dental professionals. Methods: The study participants were selected using non-probability sampling methods, as dentists and dental hygienists with more than 3 years of work experience at dental institutions. A total of 15 participants were selected, including 6 dentists, 4 clinical dental hygienists, and 5 public dental hygienists. Interviews were conducted in June and July 2022, and two focus group interviews were conducted for each group. The first round was face-to-face and the second round was conducted through an online video conference. Results: Through focus group interviews, five factors were obtained; lack of awareness, value of training, factors necessary for implementation, performance status, and obstructive factors. It was found that most study participants had a negative perception regarding the application of oral muscle strength training for elder people due to the lack of information and education on the subject. However, the benefit of oral muscle strength training was positively recognized; adequate educational material, appropriate compensation, adequate time, and availability of patients will be necessary for proper training. Conclusions: It is necessary to improve the perceptions regarding the importance of strengthening oral muscles for the elder people among dentists and dental hygienists. In addition, high-quality educational material that can be easily comprehended and practiced should be developed for effective training.

Objectives The purpose of this study was to reveal that Sasang constitution(SC) was associated with hypertension and pre-hypertension and could be a risk factor. Methods We introduced this study to educational personnel in D university in Daejeon, and 275 subjects joined this study. The SC classification was conducted with KS 15 questionnaire. The subjected measured the blood pressure with Jawon medical device automatically after 10 minute rest. The hypertension and pre-hypertension was classified by the guide of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. The frequency analysis and T-test was used in general characteristics, and chi-square test was also used between SC and pre-hypertension and hypertension. Logistic regression was used to calculate the odds ratios (ORs) and 95% confidence interval (95% CI) for pre-hypertension and hypertension. Results The number of Taeeumin(TE), Soeumin(SE), and Soyangin(SY) was 142, 71, and 61 respectively. There was significantly different in systolic and diastolic blood pressure among SC types(p<.001). The distribution of the normal group, pre-hypertension and hypertension group by SC types was significantly different (p<.001). The ORs of TE was significantly increased (ORs 4.039, 95% CI=2.019-8.082 in pre-hypertension and ORs 4.235, 95% CI=1.581-11.348 in hypertension) compared with SE(p<.001), and after adjusting gender and smoking habit, it was still significantly different(p<.001). Conclusions It is possible that SC, especially TE could be a risk factor both pre-hypertension and hypertension.

Most advanced countries that are members of the World Physiotherapy have established a 4-year education system or specialized graduate school system for physical therapists based on national standards. They have also expanded their laws and systems to provide physical therapists with the autonomy and independence to offer services in their clinics. However, compared with developed countries in North America and Europe, there are issues with the autonomy and independence of physical therapists in Korea related to national regulations. Social status and recognition of the profession are also lagging. Korea is expected to become a super-aged society by 2025. To reduce the financial burden of healthcare and welfare on the government, it is necessary to extend the time spent by older adults on independent activities and minimize their time spent using medical services. To achieve this goal and maximize the active life of older adults, a plan to efficiently use licensed physical therapists in the country should be prepared. Korea should increase the license utilization rate of physical therapists to reduce waste at the national level and increase the professional hope of the younger generations of physical therapists. To create a healthcare policy focusing on the use of physical therapy personnel, similar to that in advanced countries, it is necessary to unify educational systems and produce excellent physical therapists. Providing professional autonomy can help physical therapists develop a sense of job satisfaction. Outstanding talent will choose physical therapy as a profession if they can see hope for their future careers, and if physical therapy services in Korea are similar to those delivered in advanced countries, physical therapy in Korea can develop into a healthcare service that people desire.
