Background: This study aimed to explore the current activities of pharmacists in local pharmacies for preventing narcotics addiction, identify areas for improvement, and support initiatives to enhance and expand the activities of "narcotics addiction prevention counseling pharmacies" (hereinafter referred to as "Majung Pharmacies"). Methods: Surveys were conducted targeting local community pharmacists participating in the Majung Pharmacy activities in Daegu. Results: Out of 42 pharmacists who registered in the Majung Pharmacy movement in 2021, 41 responded (response rate of 98%). After excluding three participants who met the exclusion criteria, data from 38 participants were analyzed. The participating pharmacists were generally well aware of the conditions for pharmacists to serve as "accessible experts" in the forefront of drug addiction prevention. It was observed that the activities of Majung Pharmacies, particularly among highly engaged pharmacists, led to positive effects such as an increased focus on medication counseling for psychotropic drugs, thereby enhancing their professionalism. However, a significant number of participants also expressed negative opinions. Factors such as enthusiasm for professional activities and perceptions of the pharmacist's social role were important in shaping perceptions of Majung Pharmacy activities, whether positively or negatively. Additionally, this study underlined that pharmacists in practice are highly aware of the seriousness of issues arising from the use of narcotics by prescriptions. Conclusion: Suggestions were outlined for both short-term and long-term strategies aimed at ensuring the stable growth and expansion of Majung Pharmacy initiatives.

In this paper, in order to analyze the characteristics of degradation by salt water with insulation cover and OC wire(outdoor cross-linked polyethylene insulated wire) used in power receiving system, an experimental apparatus has been designed and fabricated. An insulation cover and OC wire were installed in an experimental apparatus, and degraded in each case of 2%, 5%, 10% salinity during 12 weeks. An optical microscope was used to observe a changing process of sample surface, and an electrical safety was analyzed by measuring dielectric breakdown voltages of samples. As salinity increased, so ununiformity of sample surface increased. The breakdown wasn't produced to 50kV about samples regardless of salinity, testing period.

This research aims to develop an elementary school English e-learning system based on the 'Self-determination theory (SDT)', which is widely applied to traditional face-to-face foreign language classes. The study also attempts to verify whether SDT-a traditional motivational theory that has been applied to face-to-face classes- is effective in an e-Learning environment with students who use this newly developed system. For the purposes of this project, the following three actions were carried out. First, a motivational strategy based on SDT was deduced. In SDT, the needs for autonomy, competence, and relatedness were introduced as basic psychological needs, and assumed that these three needs provided the natural motivation for learning, growth, and development. Second, an e-Learning system was created based on the deduced motivational strategy. Third, the system was implemented in 115 private tuition academies, and education was provided to 1,400 users for one year across the country. Afterwards, by surveying users, correlation between the role of the three psychological needs in learning English, and also the correlation between each need and motivation were investigated. Research results showed that traditional motivational theories used in face-to-face classes so far were effective in an e-Learning environment.

멜라닌 색소는 피부를 보호하는 긍정적인 면을 갖고 있으나 이의 과잉생성은 기미, 주근깨, 피부 반점 등을 유발하며 멜라닌 전구물질의 독성으로 인한 세포의 사멸 및 피부암 생성이 촉진되기도 한다. 이에 적하수오와 백하수오가 멜라닌 세포의 멜라닌화에 관여하는지를 알아보기 위하여 각각의 에탄올 추출물이 tyrosinase 효소활성 및 멜라닌 생성에 미치는 영향을 조사하였다. 하수오와 백하수오의 총 폴리페놀 함량은 각각 17.31${\pm}$0.54 mg GA eq/g, 2.75${\pm}$0.22 mg GA eq/g로 나타났으며, 하수오와 백하수오의 총 플라보노이드 함량은 각각 6.38${\pm}$0.39 mg naringine eq/g, 1.34${\pm}$0.09 mg naringine eq/g로 폴리페놀과 플라보노이드 함량은 백하수오보다 하수오에서 많은 것으로 나타났다. 하수오와 백하수오의 각각 농도별에 따른 ABTS radical 소거활성은 하수오 1 mg/mL 농도에서 96.89${\pm}$0.22%로 나타났으나, 백하수오는 1 mg/mL 농도에서 6.24${\pm}$0.33%로 하수오에 비하여 소거활성이 낮게 나타났다. 에탄올 추출물에 의한 세포 생존율은 최고 100 ${\mu}g/mL$ 처리 시 하수오와 백하수오 각각에서 93.2${\pm}$1.95%, 91.07${\pm}$4.05%로 두 가지 추출물에서 유의할 만한 변화를 나타내지 않았다. 멜라닌 생성에 미치는 영향에 대하여 10 ${\mu}g/mL$ 농도에서는 각각 75.9${\pm}$2.23%, 60.77${\pm}$3.07%로 나타났으며, 100 ${\mu}g/mL$ 농도에서는 각각 42.93${\pm}$ 2.26%, 28.37${\pm}$3.05%로 처리농도가 증가함에 따라 멜라닌 생성이 점점 감소되는 경향을 보였으며 통계학적으로도 유의성이 관찰되었다. 이 결과는 하수오와 백하수오의 에탄올 추출물이 세포에 독성을 미치지 않으며 멜라닌 생성 저해에 효과적인 미백제로서의 가능성을 제시하였다.

In many reports on the reconstruction of an orbital blowout fracture, CT(computed tomography) imaging has been used for postoperative evaluation. However, in most cases, only one plane of the CT scan was presented, which may not be sufficient for accurate evaluation. This study reviewed the CT scans presented in the related 49 articles (56 cases), and investigated our patients (150 cases) to investigate where were the most frequent unfavorable reconstructions, and to determine which planes should be presented for accurate evaluation. One plane of the CT scan was presented in 70% of the cases. On the other hand, 30% of the cases presented two planes of the CT scans. In our cases, the most prevalent sites for an unfavorable reconstruction were the posterior portion of the inferior wall, and the posterior and the inferior portion of the medial wall. In order to accurately evaluate an orbital wall reconstruction, at least two planes of a CT scan are needed. For an inferior wall evaluation, both the middle and the posterior planes of the coronal section or both the coronal and the sagittal sections are necessary. In addition, for the medial wall evaluation, both the axial and the coronal sections or both the middle and the posterior planes of the coronal section are required.

An efficient method of selecting an antagonistic strain for use as a biological control agent strain was developed. In this improved method, the surface tension reduction potential of an isolate was included in the 'decision factor,' in addition to two other factors; the growth rate and pathogen inhibition. By using a statistically designed method, an isolate from the soil was selected and identified as Bacillus sp. GB 16. In the pot test, this strain showed the best performance among the isolated strains. The lowest disease incidence rate and fastest seed growth were observed when the Bacillus sp. GB 16 was used. The action of the surface tension reducing component was assumed to enhance the wetting, spreading, and residing of the antagonistic strain in the rhizosphere. This result showed that the improved selection method was quite effective in selecting the best antagonistic strain for the biological control of soilborne infectious plant pathogens.

Acupuncture treatment and control group interventions in parallel-group randomised trials of acupuncture are not always precisely reported. In an attempt to improve standards, an international group of experienced acupuncturists and researchers devised a set of recommendations, designating them STRICTA : STandards for Reporting Interventions in Controlled Trials of Acupuncture. In a further consensus-building round, the editors of several journals helped redraft the recommendations. These follow the CONSORT format, acting as an extension of the CONSORT guidelines for the specific requirements of acupuncture studies. Participating journals are publishing the STRICTA recommendations and requesting prospective authors to adhere to them when preparing reports for publication. Other journals are invited to adopt these recommendations. The intended outcome is that interventions in controlled trials of acupuncture will be more adequately reported, thereby facilitating an improvement in critical appraisal, analysis and replication of trials.

An apparent life-threatening event (ALTE) is defined as the combination of clinical presentations such as apnea, marked change in skin and muscle tone, gagging, or choking. It is a frightening event, and it predominantly occurs during infancy at a mean age of 1-3 months. The causes of ALTE are categorized into problems that are: gastrointestinal (50%), neurological (30%), respiratory (20%), cardiovascular (5%), metabolic and endocrine (2%-5%), or others such as child abuse. Up to 50% of ALTEs are idiopathic, where the cause cannot be diagnosed. Infants with an ALTE are often asymptomatic at hospital and there is no standard workup protocol for ALTE. Therefore, a detailed initial history and physical examination are important to determine the extent of the medical evaluation and treatment. Regardless of the cause of an ALTE, all infants with an ALTE should require hospitalization and continuous cardiorespiratory monitoring and evaluation for at least 24 hours. The natural course of ALTEs has seemed benign, and the outcome is generally associated with the affected infants' underlying disease. In conclusion, systemic diagnostic evaluation and adequate treatment increases the survival and quality of life for most affected infants.

Membrane biofouling impedes wide application of membrane bioreactor (MBR) for wastewater treatment. Recently, quorum sensing (QS) mechanisms are accounted for one of major mechanisms in biofouling of MBRs. In this study, vanillin was applied to investigate reduction of biofouling in MBRs. MBR sludge was analyzed to contain QS signal molecules by cross-feeding biosensor assay and HPLC. In addition, the inhibitory activity of vanillin against bacterial quorum sensing was verified using an indicator strain CV026. The vanillin doses greater than 125 mg/L to 100 mL of MBR sludge showed 25% reduction of biofilm formed on the membrane surfaces. Two MBRs, i.e., a typical MBR as a control and an MBR with vanillin, were operated. The TMP increases of the control MBR were more rapid compared to those of the MBR with the vanillin dose of 250 mg/L. The treatment efficiencies of the two MBRs on organic removal and MLSS were maintained relatively constant. Extracellular polymeric substance concentrations measured at the end of the MBR operation were 173 mg/g biocake for the control MBR and 119 mg/g biocake for the MBR with vanillin. Vanillin shows great potential as an anti-biofouling agent for MBRs without any interference on microbial activity for wastewater treatment.
