Purpose: This study was to investigate oral hygiene knowledge and the actual condition of oral care for the students in the public health and non-public health Departments. Methods: The survey sample consisted of 262 randomly selected students. 197 of them are public health-related students and 65 are non-public health-related students. The questionnaires used in this study consisted of 4 items for general information, oral health status of 2 items, 5 items for Oral hygiene knowledge and actual condition of oral care of 5 items. Collected data were analyzed by Frequency Analysis t-test and Crosstabs using SPSS(Statistical Package for Social Sciences) Win 19.0 statistics program. Results: Regarding general characteristics of the subjects, there were 53.8% of first-year student, 26.0% of second-year student and 20.2% of third-year student among 52.3% of males and 47.7% of females. The subjects received less than "100,000" won(13.0%), "100,000-190,000" won (5.0%), "200,000-290,000" won(30.9%), "300,000-390,000" won (33.2%) and more than "400,000" won(17.9%) a month for an allowance. The subjects had 'none' (44.3%), '1'(6.5%), '2'(12.6%), '3'(5.0%), '4'(5.3%), 'more than' 5(0.8%) of dental caries and 'do not know' were 25.6%. The numbers of dental prosthetics were 'no' (35.5%), '1'(13.7%), '2'(17.2%), '3'(10.3%), '4'(11.5%), and 'more than 5'(11.8%). The public health students(84.8%) had a higher positive response rate than the non-public health students(66.2%). The public health students(80.2%) had a higher negative response rate than the non-public health students(78.5%) in the result of onset of gum disease pain awareness. The non-public health students(65.5%) had a higher negative response rate than the public health students(68.3%)) in the result of heredity of gum disease. The t-test showed that public health-related department students(M=8.264, SD=0.821) had more knowledge about oral hygiene than non-public health-related department students(M=8.015, SD=1.082). 'do not use' in the oral care products except toothpaste and toothbrush showed that public health-related department students(60.4%) use the products more than non-public health-related department students(66.2%). Conclusion: In this study, public health-related department students had higher oral hygiene knowledge and actual condition of oral care compared to non-public health-related students, but low in practical action. Due to the lower level of dental care products use in non-public health-related department, a continuous oral care education program is required.

The removal of turbidity from $TiO_2$ wastewater by an electrocoagulation/flotation process was studied in a batch reactor. The response surface methodology (RSM) was applied to evaluate the simple and combined effects of the three main independent parameters, current, NaCl dosage and initial pH of the $TiO_2$ solution on the turbidity removal efficiency, and to optimize the operating conditions of the treatment process. The reaction of electrocoagulation/flotation was modeled by use of the Box-Behnken method, which was used for the fitting of a 2nd order response surface model. The application of RSM yielded the following regression equation, which is an empirical relationship between the turbidity removal efficiency of $TiO_2$ wastewater and test variables in uncoded unit: Turbidity removal (%)=69.76+59.76Current+11.98NaCl+4.67pH+5.00Current${\times}$pH-160.11$Current^2-0.34pH^2$. The optimum current, NaCl dosage and pH of the $TiO_2$ solution to reach maximum removal rates were found to be 0.186 A, 0.161 g/l and 7.599, respectively. This study clearly showed that response surface methodology was one of the most suitable method to optimize the operating conditions for maximizing the turbidity removal. Graphical response surface and contour plots were used to locate the optimum point.

Purpose: Abdominal migraine (AM) is a very common functional gastrointestinal disorder in children. This study reports the clinical features and response of AM to prophylactic treatment in children. Methods: This retrospective study was conducted between January 2010 and December 2019 at the Royal Hospital in the Sultanate of Oman. This study included children aged ≤ 13 years with a diagnosis of AM based on the Rome IV criteria for functional diagnoses. Clinical, demographic, and treatment data were collected. Results: Seventy-four children were identified, of which 43 were eligible for inclusion in this study. The median age at the onset of symptoms was 7 years (range, 2-12 years). The most frequent symptoms were headache (81.4%), nausea (79.1%), and vomiting (72.1%). Of the total cohort, 46.5%, 23.3%, and 6.9% received riboflavin, pizotifen, and propranolol monotherapy, respectively. Combination therapy was also used; 16.3% of children received pizotifen and propranolol, 4.7% received riboflavin and pizotifen, and 2.3% received riboflavin and propranolol. Patients treated with propranolol monotherapy showed 100% clinical improvement and those treated with riboflavin or pizotifen monotherapy showed 90% clinical improvement. Response to combination therapy with pizotifen and propranolol was 71.4%, and with riboflavin and pizotifen was 100%. In addition, treatment response was significantly associated with the presence of vomiting (p=0.039). Conclusion: We found a favorable response to various modalities and combination treatments with riboflavin, pizotifen, and propranolol in children with AM. In addition, the presence of vomiting may predict treatment response.

Purpose: This study aimed to describe a school health teacher's experience working in a mountain village during the COVID-19 outbreak in 2021. Methods: The study used a case study method based on the school records and reports to the local office of education. Results: In T City, since the first COVID-19 case confirmed on March 8, 2020, as of May 17, 21, a total of 21 cases have occurred, including two third-year students of H Middle School. Since then, one additional case was confirmed on May 18, one more on May 25, and one more on May 27, resulting in a total of five confirmed cases. During this period, 42 students and 13 teachers were self-quarantined, all students and staff were tested for COVID-19 PCR, and students received remote classes. The role of school health teacher can be described through three categories: "collaborator", "care coordinator", and "educator". The school health teacher did a lot of work until the situation came to an end, successfully fulfilling these three roles. Conclusion: Some suggestions were made to prepare a more effective communicable disease response system suitable for public health infrastructure of non-urban area.

When patients with advanced breast cancer (ABC) are treated with neoadjuvant chemotherapy (NACT), efficacy is monitored by the extent of tumor shrinkage. Since their publication in 1981, World Health Organization (WHO) guidelines have been widely practiced in clinical trials and oncologic practice, for standardized tumor response evaluation. With advances in cancer treatment and tumor imaging, a simpler criterion based on one-dimensional rather than bi-dimensional (WHO) tumor measurement, named Response Evaluation Criteria in Solid Tumors (RECIST) was introduced in 2000. Both approaches have four response categories: complete response, partial response, stable disease and progressive disease (PD). Bi-dimensional measurement data of 151 patients with ABC were analysed with WHO and RECIST criteria to compare their response categories and inter criteria reproducibility by Kappa statistics. There was 94% concordance and 9/151 patients were recategorized with RECIST including 6/12 PD cases. RECIST therefore under-estimates and delays diagnosis of PD. This is undesirable because it may delay or negate switch over to alternate therapy. Analysis was repeated with a new criteria named RECIST-Breast (RECIST-B), with a lower threshold for PD (${\geq}10%$ rather than ${\geq}20%$ increase of RECIST). This showed higher concordance of 97% with WHO criteria and re-categorization of only 4/151 patients (1/12 PD cases). RECIST-B criteria therefore have advantages of both ease of measurement and calculations combined with excellent concordance with WHO criteria, providing a practical clinical tool for response evaluation and offering good comparison with past and current clinical trials of NACT using WHO guidelines.

A bioterrorism attack(BT) attack is the deliberate release of viruses, bacteria, fungi, and toxins used to cause illness or death in people, animal, and plants. Therefore, the healthcare workers are those who will take the main role in BT outbreak situations. The purpose of this study is to investigate current status of education for BT preparedness and response in health-related colleges. It is important to provide the BT preparedness and response to the health-allied students in case of unexpected BT outbreak. The questionnaires were collected from March 10 to June 10 in 2007 via mai l. Approximately 97.6% of the health-related professors answered that they had no experience of bioterrorism education. The contents of the bioterrorism curricula should contain the followings : definition and characteristics of the emergency and disaster, definition of bioterrorism, history of bioterrorism, general characteristics of bioterrorism, etiological agents of bioterrorism, bioterrorism response, systematic response, and medical response. Through these data, we will develop the disaster and bioterrorism preparedness curricula.

Purpose. The purpose of this study was to investigate the effect of changes in tear break-up time, accommodative response amount, and accommodative microwave on the eyes due to changes in humidity. Methods. A total of 48 adult men and women in their 20s (21.1±1.56 years old) were surveyed on dry eye questionnaires (OSID questionnaires), tear destruction time was measured by humidity (40%, 60%, 80%), and controlled reactions and controlled fine waves were measured through tactile tests. Result. As a result of the OSID questionnaire, there were 10 normal patients, 8 mild dry eyes, 1 moderate dry eye, and 5 severe dry eyes. The initial tear film destruction time was 7.34±4.67 seconds at 40% humidity, 8.99±4.75 seconds at 60% humidity, 10.26±4.52 seconds at 80% humidity, and the average tear film destruction time was 9.51±4.07 seconds at 40% humidity, 10.99±3.82 seconds at 60% humidity, and 12.05±3.42 seconds at 80% humidity. The accommodative response was -0.41~1.79D at 40% humidity, -0.34~1.79D at 60% humidity, and -0.30~2.01D at 80% humidity. The accommodative microwave was measured as 56.39~63.43dB when it was 40%, 56.41~62.64dB when it was 60%, and 55.96 ~61.13dB when it was 80%. Conclusion. As the humidity (40~80%) increased, the tear break-up time increased, and as the accommodative stimulus amount increased, the accommodative response amount increased. It was found that the accommodative microwave according to the amount of accommodative stimulation increased, and as the humidity increased, the accommodative microwave decreased.
