대장 지방종은 주로 우측 결장에 호발하고 특히 회맹판 부위와 맹장 부위에 호발한다. 또한 50~60대에 빈도가 높고 증상이 있는 환자에서 장중첩증이 높게는 40~50%에서 보고되고 있어 성인 장중첩증의 원인으로 중요한 비중을 차지한다. 특히 성인 장중첩증 및 장폐쇄의 중요 원인인 악성 종양과 임상 양상이 유사하여 감별진단이 중요하다. 저자들은 반복적인 복통을 주소로 내원한 환자에서 맹장의 4×5㎝의 점막하 지방종이 말단 회장부위와 반복적인 장중첩중이 발생했던 1례를 부분 절제술로 치료하여 양호한 임상 경과를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lipomas are one of the most common benign nonepithelial tumors of the colon which are often detected incidentally by radiologic investigation or on operation. These tumors are usually without specific symptoms. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve and the cecum. Most patients are asymptomatic. but tumors larger than 2 cm tend to produce a change in bowel habit. abdominal pain. rectorrhagia and complications including luminal obstruction or intestinal intussusception. Diagnosis can be made by colonoscopy abdominal CT. MRI, or barium enema. We report a case of lipoma of the cecum that originated in the submucosa and presented as a intussusception in a 50-year-old woman with a brief review of the literature.

지식 기반 사회는 새로운 지식과 가치를 창출하고 더불어 살 줄 아는 능력을 가진, ‘창의·인성적’ 인재를 원한다. 이에 2009 개정 교육과정은 창의․인성적 인재가 갖추어야 할 10가지 핵심역량을 제시하였고, 그 중 체육과 교육과정은 ‘문제해결능력’과 ‘자기관리능력’을 달성시키기에 적합한 교과로 분석되었다. 그러나 이것은 어디까지나 분석에 의한 결과일 뿐, 학교체육현장에서의 창의·인성 교육은 요원한 과제로 지적되고 있다. 따라서 본 연구에서는 체육과에서 지향하는 핵심가치들을 단순히 이해하는 것에서 나아가, 이러한 가치를 종합하고 창의적으로 조합할 수 있는 활용중심 교육으로 전환하기위하여 ‘창의·인성적 체육과 여가교육모형’을 개발하고자 하였다. 이를 위해 2009 개정교육과정(총론) 및 체육과 교육과정의 틀을 기준으로 여가교육 관련 문헌자료를 고찰했고, 전문가 협의과정을 거쳤다. 그 결과, 여가수용능력과 여가활용능력을 중심으로 학군별, 범교과 영역별로 여가교육 프로그램 세부내용을 개발하였다. 이는 학교체육현장에서 적용 가능한 구체적인 수업모형으로써 공교육의 창의·인성적 체육교육실현에 기여할 것이다. People want a ‘creativity and character' talented person who can create new knowledge and value, with the ability to know how to live with. 10 core competencies was proposed in 2009 revised school curriculum, physical education(P.E.) curriculum was classified suitable for 'problem solving skills' and 'self-management skills’. However, it is only for analysis, 'creativity and character' education has been pointed out to the distant challenge in school field. Therefore, the purpose of this study is to develop a leisure education model in P.E. for the creativity and character education not only for the simply understand the core value in P.E., but also, change over to the practical-use-centered education which can be combined these values creatively. For this purpose, literature(related to leisure education) review was conducted around 2009 revised curriculum and framework of the P.E. curriculum, also a process of experts consultation was done. As a result, leisure education in P.E. level was divided into 3 steps, ‘leisure acceptance ability’, ‘leisure application ability’, ‘continuous leisure education’. Also leisure education program was developed classified by school district, focusing on ‘leisure acceptance ability’, ‘leisure application ability’

Purpose: Single-port laparoscopic splenectomy has been performed sporadically. The aim of this study is to assess our experience with single-port laparoscopic splenectomy compared to conventional multiport laparoscopic surgery for the usual treatment modality for various kinds of splenic disease. Methods: Between October 2008 to February 2014, 29 patients underwent single-port laparoscopic splenectomy and 32 patients received multiport laparoscopic splenectomy. We retrospectively analyzed the clinical outcomes of single-port group and multiport group. Results: The body mass index and disease profiles of the both groups were similar. The operative times of single-port and multiport group were 113.6 ± 39.9 and 95.9 ± 38.9 minutes, respectively (P = 0.946). The operative blood loss of the two groups were 295.8 ± 301.3 and 322.5 ± 254.5 mL (P = 0.582). Postoperative retrieved splenic weight of the single-port and multiport groups were 283.9 ± 300.7 and 362.3 ± 471.8 g, respectively (P = 0.261). One single-port partial splenectomy and 6 multiport partial splenectomies were performed in this study. There was one intraoperative gastric wall injury. It occurred in single-port group, which was successfully managed during the operation. Each case was converted to laparotomy in both groups due to bleeding. There was one mortality case in the multiport laparoscopic splenectomy group, which was not related to the splenectomy. Mean hospital stay of the single-port and multiport group was 5.8 ± 2.5 and 7.3 ± 5.2 days respectively (P = 0.140). Conclusion: Single-port laparoscopic splenectomy seems to be a feasible approach for various kinds of splenic disease compared to multiport laparoscopic surgery.

In this paper, an efficient web search engine has been designed and implemented by use of data mining techniques. A data model named as TLD(transformed log data) set has been developed by reforming the access-to-page log data occurred by the user-inputted queries. The results can be summarized as follows firstly, in case of user access pattern analyses, non-accessed sites are exposed naturally to be inadequate. secondly, the dead-link is automatically informed to web master for the warning of dead-link deletion criteria required, and lastly, the searching tune has been reduced considerably for the users of high access frequencies, with the aid of re-arranging the access data order in pages, and for the highly associated sites, with the aid of data quality reflection.

Ostwald Ripening Stability of Curcumin-Loaded MCT Nanoemulsion

Sun-Hyung Kim,Yeun-Sun Ji,Eui-Seok Lee,Soon-Taek Hong 한국식품영양과학회 2016 Preventive Nutrition and Food Science Vol.21 No.3

Curcumin is a flavonoid found in the rhizome of the turmeric plant (Curcuma longa L.) and has recently attracted interest because it has numerous biological functions and therapeutic properties. In the present study, we attempted to incorporate curcumin into medium-chain triglyceride (MCT) nanoemulsions (0.15 wt% curcumin, 10 wt% MCT oil, and 10 wt% emulsifiers) with various emulsifiers [polyoxyethylene (20) sorbitan monolaurate (Tween-20), sorbitan monooleate (SM), and soy lecithin (SL)]. The physicochemical properties of the nanoemulsions including the Ostwald ripening stability were investigated. The initial droplet size was found to be 89.08 nm for the nanoemulsion with 10 wt% Tween-20 (control), and when Tween-20 was partially replaced with SM and SL, the size decreased: 73.43 nm with 4 wt% SM+6 wt% Tween-20 and 67.68 nm with 4 wt% SL+6 wt% Tween-20 (prepared at 15,000 psi). When the nanoemulsions were stored for 28 days at room temperature, the droplet size increased as the storage time increased. The largest increase was observed for the control nanoemulsion, followed by the 4 wt% SL+6 wt% Tween-20 and 4 wt% SM+6 wt% Tween-20 systems. The Turbiscan dispersion stability results strongly supported the relationship between droplet size and storage time. The time-dependent increase in droplet size was attributed to the Ostwald ripening phenomenon. Thus, the Ostwald ripening stability of curcumin-loaded MCT nanoemulsions with Tween-20 was considerably improved by partially replacing the Tween-20 with SM or SL. In addition, curcumin may have acted as an Ostwald ripening inhibitor.

장형화(Hyung Hwa Jang),홍의경(Eui Kyeong Hong) 한국정보과학회 데이터베이스 소사이어티 2006 데이타베이스 연구 Vol.22 No.3

XML은 데이터 교환의 표준으로 빠르게 자리를 잡아가고 있다. XML은 응용들 간에 상호 호환성이 가능하도록 정보 교환을 용이하게 한다. XML의 장점을 활용하고, 데이터베이스의 기능과 XML의 특징을 결합하기 위해서는 XML 문서들을 DBMS에 효율적으로 저장하고 관리해야 한다. 이 논문에서는 XML 데이터를 관계 데이터베이스 시스템에 저장하고 XQuery 질의를 통해 검색할 수 있는 프로토타입 시스템을 설계 및 구현한다. 이 시스템은 두 부분으로 구성된다. 첫 번째 부분은 XQuery 질의를 SQL 문장으로 변환하는 XQuery 질의 생성기이고, 두 번째 부분은 SQL 결과 집합으로부터 XML 문서들을 구성하는 XML 데이터 생성기이다. 마지막으로 본 논문에서는 XQuery 질의를 처리하는 시간을 측정하고, XPath 질의 처리 시스템과 성능을 비교하였다. XML is fast becoming an industry standard for data exchange. XML offers an easy information exchange that enables interoperability between applications. To take advantage of XML's features and to blend the power of a database with XML's features, XML documents should be stored efficiently and managed by DBMS. In this paper, we designed and implemented prototype system that can store XML data in relational database system and retrieve it with XQuery query. The system is composed of two parts. The first part of the system is XQuery query generator that translates XQuery to SQL statements and the second part is XML data generator that constructs XML document from SQL result set. Finally, this paper shows measurement time of processing XQuery query and compares storage performance with XPath query processing systems.

Background: Although a significant number of studies were done on focal segmental glomerulosclerosis(FSGS), its pathogenesis has not been sufficiently established yet. Recent studies suggested certain types of circulating factor(s) played an important role in development and recurrence after renal transplantation of FSGS by modifying the glomerular permeability of albumin. The purpose of this study performed on animals and through molecular-biological experiments is to certify the role of circulating factor (s), which cause proteinuria, by manipulating plasma of a FSGS patient who showed massive of proteinuria and wide effacement of glomerular epithelial foot processes in histologic examination after renal transplantation. also, whose massive proteinuria decreased significantly after plasma exchange. Methods - The patient's plasma prior to(plasma A) or post to(plasma B) plasma exchange were injected into tail veins of two groups of male Sprague-Dawley rats, six in each. The ratio of 24 hour urine protein and urine creatinine(Uprt/Ucr) was calculated for each case. The 2D gel electrophoresis was performed in plasma A and plasma B. The pattem of 2D gel electrophoresis of plasma A was compared to those of plasma B and healthy human serum. Results: Compared to control group, there was no significant differences in 24-hour Uprt/Ucr afer injecting 1, 2, 3, 5 mL of plasma A(p>0.05). There was no significant difference in 24-hour UprtAlcr between the injecting groups of plasma A and plasma B(p>0.05). We were not able to observe any new protein which did not appear in plasma B or healthy human serum in 2D gel electrophoresis. Conclusion ; These results suggest that the proteinuria developed in a few hours after renal transplantation and is related to wide effacement of glomerular epithelial foot processes, and that it may be induced by a certain factor which is eliminated by the plasma exchange or restrained by the immunosuppressive agents. However, we were not able to find certain circulating factor(s) which rapidly changes albumin permeability in the patient's plasma with FSGS.
