The aim of this study was to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) that applied herbal medicine to treat viral hepatitis B and C in order to determine the therapeutic efficacy of herbal medicine. EMBASE, Pubmed, NDSL, KMBASE, KISS, KISTI, Koreamed, Koreantk, and Oasis databases were searched to identify RCTs. The selected studies were assessed by the Cochrane group's risk of bias tool. A total of 15 RCTs were selected, and the hepatitis B virus (HBV) DNA reduction was significantly higher in patients treated with herbal medicine combined with Western medicine than in patients treated with herbal medicine. Herbal medicine combined with Western medicine was also superior to Western medicine alone in achieving hepatitis B e-antigen (HBeAg) and alanine aminotransferase [ALT] reduction. Only herbal medicine alone was not superior to Western medicine treatments in achieving HBV DNA, HBeAg, and ALT reduction.

One of difficulties with which teachers meet is to have underachievers with no willingness and motivation for study involved in class. Mathematics underachiever are average or above average in their intelligence but their actual achievement in mathematics did not coincide to their intellectual capabilities. The teaching strategy for them is to motivate them to try to study mathematics and to experience the improvement in their mathematics grade. In this paper, we choose flipped classroom as the strategy of teaching basic mathematics to math underachievers and applied it to them. Then we wanted to make sure the possibility for applying flipped classroom to teaching math underachievers through the analysis of change in the scholastic achievement of students in mathematics and mathematical disposition. The results of this study are as followings; First, when we taught basic math to underachievers using a flipped classroom, we confirm that math underachievers with active participation improved scholastic achievements significantly. Second, the flipped classroom was led to positive effects in an affective domain. In particular, it showed the most noticeable change in the area of willingness to math problem-solving and perception about the value of mathematics.

The purposes of this study are to develop a measuring instrument for perception of science classes based on the view of 'Community of Inquiry in Science Classroom' and to investigate elementary school students' perceptions with the instrument developed in the study. A total of 417 6th grade students participated in this study. As a result, first, we developed two set of questionnaire: (a) the questionnaire for the 'process of inquiry' consisted of six factors: 'problem recognition I: recognition of inconsistency,' 'problem recognition II: interests,' 'problem explanation I: hypothesis generation and examination,' 'problem explanation II: cooperative review,' 'problem solving I: reflection on the change of relationship with objects/conceptions,' and 'problem solving II: reflection on the change of relationship with community/ inquirer,' comprising a total of 42 items; (b) the questionnaire for the 'basis of inquiry' consisted of three factors:'will of conducting inquiry,' 'attitudes of conducting inquiry,' and 'structure of communication,' comprising a total of 17 items. Second, we found that elementary school students had positive recognition generally on their science classes in terms of the 'community of inquiry in science classroom,' but they had relatively negative recognition on the factors of problem recognition based on recognition of inconsistency, problem solving accompanied with reflection on the change of relationship with objects/conceptions, and attitudes of conducting inquiry based on severity and fallibilism, Finally, several suggestions for the science education were given.

The purposes of this study are to develop a measuring instrument for the analysis of science classroom culture from the perspective of Community of Practice (CoP) and to confirm its feasibility. We set the structural factors of CoP and developed preliminary questions through literature review. The validity and reliability of the instrument were examined and modified through the pilot survey participated by a total of 219, 4th, 6th, and 8th grade students. The modified instrument consisted of 5 factors of 'responsibility for learning', 'common interest', 'mutual relationships', 'open participation', and 'practice', comprising a total of 27 items. As the main survey, confirmatory factor analysis and reliability analysis of the instrument were carried out with a total 706 students of the 4th and 6th grade. This measuring instrument was validated and used for analyzing the culture of science classroom CoP of elementary school by comparing the data from the main survey in terms of structural factors, grade, gender, and teacher type. The measuring instrument is expected to be used not only for analyzing science classroom culture from the perspective of CoP, but also for offering implications for the desirable science classroom culture.

Objectives : Otomycosis is superficial fungal infection of external auditory canal accompanied with itching, pain, discharge, hearing loss, tinnitus and ear fullness. And chronic inflammation like chronic suppurative otitis media exacerbates otomycosis. The purpose of this study is to report one case of Korean medical treatment for otomycosis with chronic suppurative otitis media. Methods : This study was conducted with one case of otomycosis with chronic suppurative otitis media patient hospitalized in Ophthalmology, Otolaryngology & Dermatology Clinic of Korean medical Hospital. This patient was treated with Korean medical treatment including herbal medicine, acupuncture, pharmacopuncture and venesection. After the treatment, we took picture of external auditory canal by otoscope and evaluated subjective symptoms. Results : After the treatment, this patient had improved condition of external auditory canal and subjective symptoms. Conclusions : This study suggests that Korean medical treatment may be effective for otomycosis with chronic suppurative otitis media.

Objectives : The purpose of this study is to identify differences between suicide attempters who used zolpidem and others who used different methods in emergency department. Methods : This study classified 2,734 suicide attempters, who went to emergency department from 2009 to 2018, into zolpidem user group, another drug user group and non-drug user group. For these three groups, chisquare test and logistic regression analysis were conducted regarding sociodemographic feature and clinical feature related with suicide. Results : In the result of logistic regression analysis of a variable, which showed meaningful difference between suicide attempter group who used zolpidem and the other group who did not use the drug, the occurrence of zolpidem-using suicide attempers was related with the case where anxiolytics/hypnotics was used or the case where lethality and intention was low. In the drug intoxication group which showed similar feature, there was also a relevance between anxiolytics/hypnotics and the occurrence of zolpidem-using suicide attempts. Conclusions : This study identified significant difference of sociodemographic and clinical feature in suicide attempter group who used zolpidem and the other group. This result can contribute to plan further medicinal treatment in using zolpidem.

Objectives : This study aimed to describe the use of over-the-counter (OTC) drugs and to identify predictors for their use in the elderly living alone. Methods : This is a cross-sectional study that enrolled 1,099 subjects. Data regarding socio-demographic status, medical condition, cognition, mood disorder and use of OTC drugs were collected using self-administered questionnaire and from a specific semi-structured interview by a trained nurse. Data regarding use of OTC drugs were analyzed using descriptive statistics. Logistic regression analysis was applied to examine factors associated with the use of OTC drugs. Results : The use of OTC drugs were reported by 35.4% of the subjects. Analgesics (13.6%) was the most frequent drugs. Depression (OR=1.10, 95% CI=1.10-1.87) and comorbidities measured by cumulative illness rating scale (CIRS) (OR=1.08, 95% CI=1.03-1.12) were significantly associated with the use of OTC drugs in the elderly living alone. Conclusions : Depression and severity of underlying medical conditions could be a predictor of the use of OTC drugs in the elderly living alone. The clinicians should be vigilant regarding the potential use of nonprescription medications in the elderly.

This study attempted to understand the difficulties experienced in program development and class operation of instructors in the hands-on science class and the needs for training based on them. For this study, an online survey was conducted on 193 instructors in the hands-on science class in 2022, and interviews were conducted on 13 instructors. As a result, the difficulties of developing programs for hands-on science class instructors were due to lack of class content, lack of program development budget, lack of equipment necessary for class operation, and difficulty in applying various educational methods such as discussion and practice. The preferred training contents were in the order of the latest science and technology, reconstruction methods of existing programs, and regional specialization technology. In addition, it was found that the difficulties experienced by instructors in class management stemmed from the method of operating hands-on science classes using experience kits. Accordingly, instructor education should be provided in the direction of helping instructors to provide the best education in the situation of the hands-on science classroom.

This study aimed to evaluate the academic effectiveness of non-face-to-face classes in deciduous tooth morphology practice. Under the course name dental morphology, a total of 60 dental students took face-to-face classes while 55 pre-dental students took non-face-to-face classes. Students were required to submit their practical assignments after 5 weeks of practical classes. To evaluate the academic effectiveness of non-face-to-face classes, practical assignments were scored by an evaluator and compared with face-to-face classes using the Mann-Whitney U test and the chi-square test. The results showed that the practical score in face-to-face classes was 77.43 ± 5.97 and the practical score in non-face-to-face classes was 76.04 ± 5.83. There was no significant difference in the academic effectiveness of face-to-face classes compared to non-face-to-face classes in deciduous tooth morphology practice (p > 0.05). This study suggests that non-face-to-face classes on introductory practice such as the dental morphology course can provide comparable quality to the education taught in traditional face-to-face classes.

We need to reflect the establishment of meaning and level of 'proof and argumentation in middle school mathematics'. It should be considered as human activity through communication in community. Thus, we should design instruction from this standpoint. From this point of view, we had been operated 'Geometry Inquiry Class' aimed at middle school students in eighth grade for two years to improve current geometry class in middle school. In this study, we will observe how individual students' original proof schemes are developed and accepted to the class through the process of mutual negotiation between the teacher and students. The episode with four phases begins with the initial proof schemes students have offered. Through the negotiation of class participants, it gives birth to the proof scheme unique to the current geometry classroom. Why do we pay attention to the process? It is because we think that the value of this type of instruction lies in the process of communication and mutual understanding and mutual reference, not in the completeness of the final product. This is the very appropriate proof in the middle school mathematics classroom.
