Background: This study investigated current research trends in bee venom acupuncture in Korea. Materials and methods: The literature in Korea was reviewed using the search engines Science and Technology Society Village, Korean Studies Information Service System, National Discovery for Science Leaders, and Oriental Medicine Advanced Searching Integrated System. The keywords searched were "bee venom," "apitoxin," "apitherapy," and "bee sting." We selected 412 studies, which included Korean literary studies, experimental studies, and clinical studies. Results: We classified them by publication year, research type, disease and topic, and quality assessment. Among bee venom-related studies, clinical studies (235 studies) outnumbered experimental studies (149 studies) and literary studies (28 studies). Nineteen experimental studies concentrated on the theme of "anticancer." In the type analysis of clinical studies, lumbar disorders comprised 45 of 235 studies, followed by the effect on body. Forty-two randomized controlled trials (RCTs) have been published from 2003 to date (2015). Twenty-two studies used appropriate randomization methods. Fourteen studies had a Jadad score of 4-5 points; 15 studies, 1-3 points; and 13 studies, 0 points. Conclusions: Bee venom treatment is based on Korean traditional medicine theory. Numerous research studies suggest its effectiveness. Effort and academic approach on bee venom are expected to receive a positive evaluation.

본 연구는 디지털 케이블방송과 IPTV와 같은 디지털 미디어 서비스의 메뉴 구조에 대한 시선추적 연구이다. 최근 디지털 미디어 서비스의 초기 메뉴 구조는 수평 구조 또는 수직 구조로 제공되고 있는데, 디지털 케이블의 사례와 IPTV의 사례를 볼 때 발전과정은 상이하나, 서비스의 구성이 유사하여 메뉴 타이틀 및 방향에 대한 실험을 통해 시사점을 얻을 수 있을 것이라 판단이 된다. 연구자는 연구주제로 사용자가 메뉴를 조작하면서 인지하는 메뉴 타이틀 인지 정도와 메뉴의 제공방향에 대한 시선 도달시간이 상이한지 확인하고, 논의하는 것으로 정하였다. 연구는 Vertical Type과 Horizontal Type으로 구분된 실험을 통해 각 9가지의 결과를 도출하는 것으로 초기 메뉴에서 선순위로 노출되는 실시간 방송의 경우 수직구조의 메뉴에서, 지상파 및 영화VOD와 같은 후순위 메뉴 서비스의 경우는 수평 구조에서 피험자의 시선이 빠르게 이동한 것을 확인하였다. 연구의 결과는 기존 미디어사업자들의 메뉴 구조진화를 간접적으로 설명하는 것으로 향후의 진화 방향을 설정할 때 실무적으로 도움이 되는 유용한 결과이다.

Purpose: This study was done to identify the experiences of ethical issues and needs for ethics education in clinical nurses. Methods: A cross-sectional survey was used and data were collected in 2013. Participants were 428 clinical nurses working in the general units of seven medical hospitals. The Ethical Issues in Clinical Practice Tool was used. Data analysis was performed using SPSS/WIN 19.0. Results: 'Providing care with a possible risk to your health' was the most frequent and disturbing ethical problems for nurses. The highest helpful ethical topic was 'the patients' right, autonomy and informed consent'. The ethical issue experience was significantly different according to education level, work units, and type of employment. The necessity of ethics education was statistically different according to age, religion, level of education, duration of working as RN, position, shift type, and continuing education about nursing ethics. Conclusion: The results of this study show that nursing educators need to provide practical ethics education based on frequent ethical issues and helpful education topics. These findings can be used in developing effective education strategies for clinical nurses and nursing organizations to improve nurses' ethical decision-making abilities.

기존 동영상 부호화 표준보다 더 높은 효율의 표준에 대한 수요가 커지면서, 최근 MPEG과 VCEG에서 Versatile Video Coding(VVC)이라는 차세대 동영상 부호화 프로젝트를 개발하고 표준화하고 있다. 압축 효율 증대를 위하여 다양한 화면간 부호화 기법이 등장하였으며, 특히 움직임 벡터의 적응적인 해상도 부호화가 등장하여 VVC의 압축 효율을 올리는데 기여하였다. 다만, 최적의 움직임 벡터 해상도를 결정하기 위해 부호화기에서 다양한 율-왜곡 비용을 계산해야 했기에, 부호화기 시간 복잡도가 높아지게 되었다. 실시간 동영상 방송 및 스트리밍 서비스를 위해서는 부호화기의 복잡도를 줄이는 것이 필요하나, 아직 적응적 움직임 벡터 해상도 결정기법에 대한 복잡도 감소 연구는 미개척분야이다. 따라서, 본 논문에서는 이 움직임 벡터 해상도 결정을 위한 부호화 복잡도를 줄이는 연구를 제안한다. 이를 위해, VVC의 특별한 트리 구조인 multi-type tree 구조 내에서의 부호화된 문맥을 활용한 고속 결정기법을 고안한다. 실험 결과, 본 고속결정 기법은 VVC 참조 소프트웨어 대비 약간의 압축효율 감소 내에서 10%의 전체 부호화 시간을 줄임을 확인하였다.

The history of foot-binding was once regarded as a unique practice accentuating the beauty of a woman and the culture of the costume, to be found nowhere except in China. This thesis makes it an aim to understand the culture of costume in China by analyzing the beauty of foot-binding, and its meanings associated with the historical background of the costume. The method of investigation was by both previous literature on the topic and case analysis. The shoes were analyzed by colors, patterns and decorations; selecting 70 pieces easily accessible in the Tianjin Huaxia Shoes Culture Museum. In terms of form, the general type was of the most frequent, followed by one with an elevated toe, mixed type, and one of the downward toe, sequentially. The color of foot-binding shoes were mostly vivid chromatic colors, while the achromatic ones like black and grey constituting significant portions. In view of the patterns, plants patterns were the most frequent, followed by the mixed patterns of mostly flowers with butterflies, bats, and birds desiring the prosperity of descendants. In view of the ornaments, embroidery was the most frequent, while the mixed shoes included tassels, sequins, applique, and shoes without ornaments were of distributions. The forms, colors, patterns and ornaments clearly associated with the wishes of artistic beauty, sexuality, and rise in women's social status may be in the hope of leading others to understand the costume culture embedded in the Chinese by providing important clues about them.

Objectives The purpose of this review was to analyze the research trends in clinical research related to pelvic malposition published in Korean medicine journals. Methods We searched articles in Korean databases (OASIS, NDSL, RISS, and KTKP), and sorted the articles by publishing date, pelvic malposition type, field of study, and measurement index. Results 1. 25 original articles and 9 case report articles were reviewed. 2. In recent years, this topic has been studied more frequently, with an increasing number of original articles published. 3. 16 articles analyzed pelvic malposition type. And half of the articles focused on ilium. 4. The original articles have figured out the correlation between pelvic malposition measurement indices and other measurement indices or diseases. 5. Treatment tools, such as chuna therapy, the mckenzie method, devices for correcting malposition, acupuncture were used in the case report articles. 6. 29 measurement indices, such as Ferguson's angle, Ilium shadow measurement, and Iliac height difference were used. Conclusions According to the literature, pelvic malposition is related to other diseases and measurement indices, and manual medicine on pelvic malposition can be effective. However, due to the lack of sufficient empirical evidence from medical articles to support this, further clinical research should be conducted.

A Typically-Perceived-Situation(TPS) is a situation which might be useful for conceptual learning of science, rising spontaneously in an individual's mind when someone is thinking about, or in relation to, any object such as physical object, concept, situation, etc. But, for a discussion about the TPS' usefulness in depth, we need to analyze the specific features of the TPS in relation to conceptual learning of science. This study investigated four elementary school students' TPSs related to the topic of the action of force, especially (a) 'the situation where force is being acted on an object', and (b) 'the situation where force is not being acted on an object', with an interview as well as with a drawing-and-explanation type questionnaire. Their TPSs were then compared with their concepts, checked by a misconception questionnaire of choice-and-explanation type. The results showed that the students' TPSs illustrated not only their conceptions about the action of force, but also gave more fruitful details of their ideas, including (a) clues of their conceptions, (b) concrete situations, and (c) their past experiences with emotional components. On the whole, the TPS's appeared to be rather stable, affected by their past experiences, and needed to be analyzed into their sub-units for more subtle details. Finally, some practical ways of how to apply the ideas of the TPS to the conceptual learning of science are suggested.

Recently, the control of pore-characteristics of nano-porous materials has been studied extensively because of their unique applications, which includes size-selective separation, gas adsorption/storage, heterogeneous catalysis, etc. The most widely adopted techniques for controlling pore characteristics include the utilization of pillar effect by metal oxide and of templates such as zeolites. More recently, coordination polymers constructed by transition metal ions and bridging organic ligands have afforded new types of nano-porous materials, porous metal-organic framework(porous MOF), with high degree and uniformity of porosity. The pore characteristics of these porous MOFs can be designed by controlling the coordination number and geometry of selected metal, e.g transition metal and rare-earth metal, and the size, rigidity, and coordination site of ligand. The synthesis of porous MOF by the assembly of metal ions with di-, tri-, and poly-topic N-bound organic linkers such as 4,4'-bipyridine(BPY) or multidentate linkers such as carboxylates, which allow for the formation of more rigid frameworks due to their ability to aggregate metal ions into M-O-C cluster, have been reported. Other porous MOF from co-ligand system or the ligand with both C-O and C-N type linkage can afford to control the shape and size of pores. Furthermore, for the rigidity and thermal stability of porous MOF, ring-type ligand such as porphyrin derivatives and ligands with ability of secondary bonding such as hydrogen and ionic bonding have been studied.

Local anesthesia is indispensable in dentistry. Worldwide, millions of local anesthetic injections are administered annually, and are generally considered safe invasive procedures. However, adverse effects are possible, of which dentists should be aware of. This scoping review aimed to provide an extensive overview of the reported literature on the adverse effects of dental local anesthesia. The types of papers, what is reported, and how they are reported were reviewed. Additionally, the incidence and duration of adverse effects and factors influencing their occurrence were also reviewed. An electronic search for relevant articles was performed in PubMed and Embase databases from inception to January 2, 2020. The titles and abstracts were independently screened by two reviewers. The analysis was narrative, and no meta-analysis was performed. This study included 78 articles. Ocular and neurological adverse effects, allergies, hematomas, needle breakage, tissue necrosis, blanching, jaw ankylosis, osteomyelitis, and isolated atrial fibrillation have been described. Multiple adverse effects of dental local anesthesia have been reported in the literature. The results were heterogeneous, and detailed descriptions of the related procedures were lacking. Vital information concerning adverse effects, such as the dosage or type of anesthetic solution, or the type of needle used, was frequently missing. Therefore, high-quality research on this topic is needed. Finally, the adverse effects that are rarely encountered in real-world general practice are overrepresented in the literature.
