현재의 전자투표 시스템은 투표자로 하여금 일방적인 신뢰를 강요하고 있으며, 투표자의 의도대로 기록되었음을 입증하지도 않는다. 전자투표가 종이투표 방식보다 많은 장점을 제공할 것이라고 기대하고 있음에도 불구하고 이러한 신뢰성 결여는 전자투표 실시를 막는 주요 요인이 되고 있다. 많은 전문가들은 투표자에게 투표기가 정확하게 동작하고 있음을 확신시키기 위해 영수증을 발급하는 방안을 긍정적으로 고려하고 있다. 본 논문에서는 이미 잘 알려진 cut-and-choose 방식을 응용한 영수증 발급 방식을 제안한다. 제안하는 방식은 특수한 영수증 출력 장치나 제삼자에 의한 투표기 검증 등이 필요없으며, 기존 방식보다 높은 안전성을 제공한다.

Using data from a departmental profit and loss management questionnaire survey conducted for a group of hospitals consisting of various establishment entities, this study evaluates the effectiveness of departmental profit and loss management practices, such as break-even analysis, based on objective performance data. The study also examines whether the implementation of departmental profit and loss accounting is still effective in improving profitability in the financial year 2021 and whether the effectiveness of the implementation of departmental profit and loss accounting is robust. This study reconfirmed that the implementation of departmental profit-and-loss accounting has a positive effect on objective financial performance in hospitals and that the effect of improving profitability can be enhanced by implementing it monthly with high frequency and regularity and by using the accounting results more actively. It was also found that the department's implementation of break-even analysis had a positive impact on financial performance, which was enhanced by more active use of the data. Given the current economic climate, a hospital organization's active participation in income statement management, not only for the hospital as a whole but also for each department, would be an effective management activity.

Objectives The purpose of this study was to investigate Korean medicine treatment on hemifacial spasm and to suggest future research direction. Methods We used seven electronic databases to find articles on Korean medicine treatment of hemifacial spasm and by analyzing the title, abstract, and main text, articles elucidating on Korean medicine treatment on hemifacial spasms were included. Results A total of 68 articles were searched from seven electronic databases. Excluding duplicate articles and articles that satisfied the exclusion criteria, nine articles were included in this study. Acupuncture was used in nine cases, herbal medicine in five cases, physical therapy in three cases, and cupping therapy in one case. In acupuncture, general acupuncture was used in five cases, pharmacopuncture in three cases, and Meridian tendino-musculature acupuncture and thread-embedding therapy in two cases each. Gamigwibi-tang used in two cases was the most frequently used herbal medicine. In physical therapy, carbone, hot pack, interferential current therapy, and silver spike point were used in two cases each. Conclusions It was confirmed that Korean medicine treatment for hemifacial spasm was attempted in varying methods and nearly all cases included in this study showed improvement. However, because of the low level of evidence due to the nature of these case reports, further studies should be conducted for an objective comparison and analysis on the effect of Korean medicine treatment compared to existing treatments.

Assistive technologies are necessary for ensuring independent living and equal participation in an information-based society for people living with disabilities (PLWD). This study investigated the assistive technology preference of students with visual disabilities, and the approach academic libraries should adopt in procuring assistive technologies. The study adopted a quantitative research method, with a survey as the research design. The study was conducted among visually disabled students in four public universities in Nigeria. Using the total enumeration method, an online questionnaire was used to obtain information from 151 students who voluntarily agreed to partake in the survey. The study found that access to electronic resources, scanning/conversion of print resources to electronic formats and access to information on the Web were among the technology-based services provided to visually disabled students. COBRA, ZoomText, Supernova and Dragon Naturally Speaking are the most preferred assistive technologies (software). At the same time, handheld scanners ($\bar{x}=4.40$) and braille keyboards ($\bar{x}=4.60$) are the most preferred assistive technologies in the hardware category by visually challenged students. The study further revealed that the library management should consult with students living with a visual disability before procuring assistive technology. Findings from this study thus provide further evidence of the need for librarians to fulfil their moral and legal obligation in advocating the provision of assistive technologies. Library administrators and university stakeholders should expedite actions on meeting the assistive technology needs of people living with visual disabilities. These actions should transcend mere policy formulation on the provision of assistive technologies to restructuring their services and spaces to accommodate assistive technologies as information service delivery tools for people with visual disabilities.

The efficient management of pain and discomfort is essential for successful dental treatment and patient compliance. Dental professionals are commonly evaluated for their ability to perform treatment with minimal patient discomfort. Despite advancements in traditional local dental anesthesia techniques, the pain and discomfort associated with injections remain a concern. This scoping review aims to provide a comprehensive overview of the literature on novel dental anesthetics and associated devices designed to alleviate pain and discomfort during dental procedures. The Joanna Briggs Institute and the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews guidelines were used to prepare the review. Six databases and two sources of gray literature were searched. This review analyzed 107 sources from 1994 to 2023. Local anesthesia devices were grouped into computer-controlled local anesthetic delivery (CCLAD) systems, intraosseous anesthesia (IOA), vibratory stimulation devices, and electronic dental anesthesia (EDA). CCLAD systems, particularly the Wand and Single-Tooth Anesthesia, have been the most researched, with mixed results regarding their effectiveness in reducing pain during needle insertion compared to traditional syringes. However, CCLAD systems often demonstrated efficacy in reducing pain during anesthetic deposition, especially during palatal injections. Limited studies on IOA devices have reported effective pain alleviation. Vibrating devices have shown inconsistent results in terms of pain reduction, with some studies suggesting their primary benefit is during needle insertion rather than during the administration phase. EDA devices are effective in reducing discomfort but have found limited applicability. These findings suggest that the CCLAD systems reduce injection pain and discomfort. However, the evidence for other devices is limited and inconsistent. The development and research of innovative technologies for reducing dental pain and anxiety provides opportunities for interdisciplinary collaboration and improved patient care in dental practice.

Plasma enhanced chemical vapor deposition (PECVD) silicon dioxide thin films have many applications in semiconductor manufacturing such as inter-level dielectric and gate dielectric metal oxide semiconductor field effect transistors (MOSFETs). Fundamental chemical reaction for the formation of SiO2 includes SiH4 and O2, but mixture of SiH4 and N2O is preferable because of lower hydrogen concentration in the deposited film [1]. It is also known that binding energy of N-N is higher than that of N-O, so the particle generation by molecular reaction can be reduced by reducing reactive nitrogen during the deposition process. However, nitrous oxide (N2O) gives rise to nitric oxide (NO) on reaction with oxygen atoms, which in turn reacts with ozone. NO became a greenhouse gas which is naturally occurred regulating of stratospheric ozone. In fact, it takes global warming effect about 300 times higher than carbon dioxide (CO2). Industries regard that N2O is inevitable for their device fabrication; however, it is worthwhile to develop a marginable nitrous oxide free process for university lab classes considering educational and environmental purpose. In this paper, we developed environmental friendly and material cost efficient SiO2 deposition process by substituting N2O with O2 targeting university hands-on laboratory course. Experiment was performed by two level statistical design of experiment (DOE) with three process parameters including RF power, susceptor temperature, and oxygen gas flow. Responses of interests to optimize the process were deposition rate, film uniformity, surface roughness, and electrical dielectric property. We observed some power like particle formation on wafer in some experiment, and we postulate that the thermal and electrical energy to dissociate gas molecule was relatively lower than other runs. However, we were able to find a marginable process region with less than 3% uniformity requirement in our process optimization goal. Surface roughness measured by atomic force microscopy (AFM) presented some evidence of the agglomeration of silane related particles, and the result was still satisfactory for the purpose of this research. This newly developed SiO2 deposition process is currently under verification with repeated experimental run on 4 inches wafer, and it will be adopted to Semiconductor Material and Process course offered in the Department of Electronic Engineering at Myongji University from spring semester in 2012.

Objective: To date, only a few studies have investigated the relationships between genetic polymorphisms and external apical root resorption (EARR). Hence, the aim of this systematic review was to explore the relationship between different gene polymorphisms and their association with EARR. Methods: A complete literature search was conducted by two independent reviewers. The PubMed, Science Direct, and Scopus databases were searched. In addition, the bibliographies of all textbooks and relevant articles were searched manually. A meta-analysis was performed using data entered into the electronic databases until February 28, 2017. Results: On the basis of the search, we identified 17 and 7 publications for the systematic review and meta-analysis, respectively. Odds ratio (OR) was used to evaluate the association of the interleukin 1B (+3954) polymorphism and the risk of EARR. The overall OR from the studies was used to estimate the risk of EARR. However, no association was found and no publication bias was apparent for the risk of EARR in patients receiving orthodontic treatment. Conclusions: More research on the relationship between gene polymorphism and EARR is necessary to determine better specificity of possible interactions.
