분화갑상선암의 수술 전 병기결정: 영상의학적 검사의 의의
정기욱 대한갑상선학회 2011 International Journal of Thyroidology Vol.4 No.2
Staging is the process of determining how much cancer there is in the body and where it is located. Correct staging helps the oncologist to plan a treatment and determine a prognosis. For the surgeon’s perspective,planning of surgical treatment is the main concern in preoperative staging. Preoperative staging would be synonym of “preoperative planning” or “preoperative localization” in this context. Extent of primary tumor and lymph node status is the main factor to decide initial surgical treatment of well-differentiated thyroid carcinomas (WDTC). Precise description of lymph node status is also important in the planning of surgery for WDTC. Surgeon performed preoperative ultrasound is highly recommended in the planning of surgery,especially in recurrent cases. There have been debates for what the best imaging modality is in the preoperative staging of WDTC. Surgeon should understand pros and cons of each modality and should communicate with radiologist to decide surgical plan. In this article, we will discuss importance of radiological imaging in preoperative staging of WDTC.
An Asian perspective on irritable bowel syndrome
정기욱,명승재 대한장연구학회 2023 Intestinal Research Vol.21 No.2
Irritable bowel syndrome (IBS) is a prevalent chronic disorder, and its epidemiology depends on the diagnostic criteria used. Recently, the Rome IV criteria for IBS were published by changing the frequency of abdominal pain and excluding abdominal discomfort from the previously used Rome III criteria. However, the recent Asian consensus on IBS recommends the inclusion of abdominal discomfort and abdominal pain as diagnostic criteria. The low fermentable oligo-, di-, mono-saccharides, and polyols (FODMAP) diet has been proven to be effective in Western patients. Moreover, recent well-designed studies reported its effectiveness and the microbial changes after implementing it in Asian patients with IBS. However, traditional Korean foods including kimchi, one of representative FODMAP-rich food, exhibited a poor correlation with the food-related symptoms of IBS. Therefore, the low FODMAP diet protocol should be cautiously applied to IBS patients, especially to Korean patients with IBS. In Asian countries, there are lots of traditional herbal medicines and treatments for IBS; however, these studies have limitations including the heterogeneity of herbal mixtures and relatively small sample size. Therefore, well-designed studies based on large samples are required to validate complementary and alternative medicine in the treatment of Asian patients with IBS.

Discovering the suppliers capable of manufacturing the parts that satisfy buyer requirements via current online market places remains difficult due to semantic differences between what the suppliers can produce and what the buyer wants to acquire. One of the promising approaches to overcome the semantic difference is to adopt an ontology to describe the suppliers' manufacturing capabilities and the buyer requirements that range widely from manufacturing costs to eco-friendly design. Such an ontology dedicated to supplier discovery has yet to be developed. MSDL(Manufacturing Service Description Language) provides the basis for defining terms and their relationships in the ontology. Thus, the objective of this paper is to extend MSDL into a new ontology suitable for supplier discovery in mold manufacturing industry. In addition, a new ontology development method for supplier discovery will be proposed. Finally prototype demonstrations are provided to show a feasibility of the proposed ontology in mold manufacturing domains.
