  • The increased use of cone-beam computed tomographic (CBCT) scans has made it increasingly necessary to evaluate incidental findings on CBCT scans. This report describes the case of a 66-year-old female patient who presented to the Department of Oral and Maxillofacial Pathology, Radiology and Medicine at the College of Dentistry of the author's institution and underwent a CBCT scan for maxillary alveolar process implant planning. Upon evaluation of the CBCT scan, a radiopaque (soft tissue attenuation) mass in the left superior aspect of the nasal cavity and left locule of the sphenoid sinus with opacification of the left locule of the sphenoid sinus was incidentally noted. These radiographic findings were suggestive of a space-occupying mass with a high possibility of malignancy. A further medical evaluation confirmed renal cell cancer metastasis to the sphenoid sinus. This study shows the significance of reviewing the entire CBCT scan for incidental findings.

  • Breast augmentation is becoming more common, be it for cosmetic reasons or post-mastectomy. Multiple articles in the literature describe the imaging findings of various types of cosmetic breast augmentation. Some articles describe imaging findings for different types of post-mastectomy reconstructions. This essay aims to serve as a comprehensive reference for the multimodality imaging of various types of breast augmentations in native breast and post-mastectomy reconstructions. Familiarity with these findings will facilitate the detection of complications and new or recurrent breast malignancies in patients. With the extensive illustrations provided in this essay on normal and abnormal imaging findings of augmented breasts, readers will receive exposure that will facilitate effective practice.

  • The purpose of this paper is to understand the profiles of users and their motivations in sharing research articles on Twitter. The goal is to contribute to the understanding of Twitter as a new altmetric measure for assessing impact of research articles. In this paper, we extended the previous study of tweet motivations by finding out the profiles of twitter users. In particular, we examined six characteristics of users: gender, geographic distribution, academic, non-academic, individual, and organization. Out of several, we would like to highlight here three key findings. First, a great majority of users (86%) were from North America and Europe indicating the possibility that, if in general, tweets for research articles are mainly in English, Twitter as an alternative metric has a Western bias. Second, several previous altmetrics studies suggested that tweets, and altmetrics in general, do not indicate scholarly impact due to their low correlation with citation counts. This study provides further details in this aspect by revealing that most tweets (77%) were by individual users, 67% of whom were nonacademic. Therefore, tweets mostly reflect impact of research articles on the general public, rather than on academia. Finally, analysis from profiles and motivations showed that the majority of tweets (from 42% to 57%) in all user types highlighted the summary or findings of the article indicating that tweets are a new way of communicating research findings.

  • The bone regeneration effects of copper oxide on experimentally induced fibular fracture were examined in 36 New Zealand white male rabbits. They were divided into two groups: non-treated group (control group) and copper oxide treated group (treatment group). A fibular fracture was created by an osteotomy in the middle of the fibula and 62.5 mg/kg of copper oxide was orally administrated during 7 days after operation in the treatment group. Radiological findings, histopathological examinations and hematoserological findings were observed to evaluate the bone regeneration effects of copper oxide on fibula fracture during 9 weeks. In radiological findings, the area of bone regeneration at the fracture site of the treatment group was significantly wider from 3 weeks to 6 weeks after administration of copper oxide than those of the control group (p < 0.05). In histopathological examinations, fracture healing in treatment group was faster than in control group. Also, histopathological responses of thick bony trabeculae and new bone marrow formation were shown in the treatment group, whereas many fibrous tissues and cartilages were mainly observed in the control group. No specific effects of copper oxide on the body was found in hematological and serological test during experimental period. These results showed that the copper oxide had a potential therapeutic application in the treatment of fracture and bone trauma.

  • The recent interest in regions represents a rise of the new regionalism. Three competing theories provide the frameworks of explaining the ascendance of regions as the meaningful vessel of territorial economic and political processes. They are the orthodox new regionalism, the new politics of scale, and the relational topology of networked actors. Referring to these theories, this paper assesses the establishment of cross-provincial Area-wide Economic Regions (AERs) in Korea. The findings indicate that AERs represent a radical shift to a new regionalism. However, it is misconceived to see their ascendance as the orthodox new regionalism, as they marginally fit the hollowing-out of the state thesis. Nor they show distinct features to which the politically-inflicted regionalism is attributed. In consequence, AERs represent the emergence of a new regionalism that is consequent of the unique politico-economic context of Korea, say, a most centralized state-society combined with the neoliberalizing policy process emanating from the globalization pressures.

  • Purpose - This paper analyzes the effect of the agricultural export market for Korea's new southern countries in consideration of logistics efficiency. In order to expand Korean agricultural exports, the logistics performance index, national income, per capita income, consumer price index, distance and FTA are included. Through empirical analysis, the impact of logistics efficiency on Korean agricultural exports is derived and measures are proposed to expand exports in the future. Design/methodology - The analytical model of this study takes into account the import demand factors of the new southern countries for Korean agricultural exports. A research model was established based on prior research based on the gravity model, which is widely used in international trade effect analysis. In particular, logistics efficiency measures the effect on Korean agricultural exports using the logistics performance index and examines the effect by deriving factors for export expansion. Findings - The main findings of this study can be summarized as follows: The higher the logistics efficiency of the new southern countries in exporting Korean agricultural products, the more directly they have an effect on expanding exports. In addition, it was analyzed that the expansion of Korean agricultural exports has a positive effect on the other countries' national income, per capita income, consumer price index, population, and FTA. Based on these results, the importance of efficient logistics management in agricultural exports has been emphasized. Originality/value - There are not many studies on the export of agricultural products by logistics efficiency. However, prior studies that have adapted to manufacturing and other areas suggest that logistics efficiency has a direct effect on exports. This study suggests that Korean agricultural products are directly effective in exporting to new southern countries in terms of logistics efficiency. This can be an important time point in recognizing that logistics capabilities are important to ensure new books and the safety of agricultural products.

  • This paper proposes a new aesthetic methodology analyzing the objectives and activity of audience members through the application of the concept of monophony and polyphony to interactive artwork. Monophony and polyphony were new methods for analyzing the voices of speakers in literature as Mikhail Bakhtin, a Russian aesthetic theorist, proposed. This paper proposes a new methodology for analyzing structure and the elements of monophony and polyphony in interactive artwork based on previous studies. Through this new methodology, I have analyzed a total of 9 interactive artworks. As a result, I have found detailed elements of monophony and polyphony in those artworks. This paper also proposes new findings: non-controlled types and controlled types appeared in the interactive artwork under the concept of polyphony. Through these new findings, artists and researchers can apply objectives and activities in interactive artwork through the participation of audience members, thereby leading to new aesthetics in interactive artwork.

  • This study examines existing literature and uses case studies to identify the scope of fashion blogging and the evolving role of the personal style bloggers in the fashion business. Information on six popular personal style bloggers has been gathered to demonstrate the evolving business of these bloggers and their scope of operations that are relevant to fashion. The case of these six bloggers were drawn from popular media publications such as CNN, Wall Street Journal (WSJ), Time, Women's Wear Daily (WWD) and The New York Times. The case study of these six bloggers reveals that these personal style bloggers have used their reach and influence on the blog audience to procure and access business opportunities to grow their enterprise. The findings indicate that affiliation, partnership or collaboration with brands or established designers adds more value to a personal style bloggers resume. However, the findings also indicate that the popular fashion bloggers provide a new opportunity for marketing and promoting fashion brands and products to the younger generation.

  • This study was designed to evaluate a repeated oral dose toxicity of a new hepatotherapeutic agent GODEX in Sprague-Dawley rats. Male and female rats were orally administered with dosages of 500, 100, 20, and 0 /kg/day of GODEX daily for 4 weeks, respectively. There were no dose-related changes in clinical signs, body weight changes, food and water consumption, opthalmoscopy, organ weights, urine analysis, biochemical examination, and hematological findings of all animals treated with GODEX. Gross and histopathological findings revealed no evidence of specific toxicity related to GODEX. These indicate that GODEX may have no side effects and its oral maximum tolerated dose value may be over 500 mg/kg in rats.
