Hence, the documents can be handled efficiently. The relational database structure is recommended for the system and also a hybrid approach is discussed for multimedia information in the text. Functions for each module of the system are defined and conceptual and practical design issues are provided.

혼합 네트워크 상의 Chinese Postman Problem을 위한 유전자 알고리즘

전병현,한치근 경희대학교 산학협력기술연구원 1998 산학협력기술연구논문집 Vol.4 No.-

The Chinese Postman Problem(CPP) is to find a shortest tour traversing all the edges or arcs at least once in a given network. The Chinese Postman Problem on Mixed network(MCPP) has been shown to be NP_complete. For this reason, heuristic methods have been proposed to obtain near optimal solutions of the MCPP with low cost of computing. In this paper, we propose a genetic algorithm that solves the MCPP. Through the computational experiments, it is found that the proposed method is better than the existing heuristic methods.

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.

In this paper, we design a GA-fuzzy controller for position control and anti-swing at the destination point. Applied genetic algorithm is used to complement the demerit such as the difficulty of the component selection of fuzzy controller, namely, scaling factor, membership function and control rules. Lagrange equation is used to represent the motion equation of trolley and load in order to obtain mathematical modelling. Simulation results show that the proposed control technique is superior to a conventional optimal control in destination point moving and modification.

In an effort to optimize tissue culture responses of zoysiagrass (Zoysia japonica Steud.) for genetic transformation, factors affecting callus induction and plant regeneration were investigated. MS medium containing 3 ㎎/L 2,4-D was optimal for embryogenic callus induction from mature seed. The plant regeneration frequency of 73.3% was observed when embryogenic calli induced in this medium were transferred to N6 medium supplemented with 0.1 ㎎/L 2,4-D and 5 ㎎/L BA. Among several basic media, MS and N6 medium were optimal for callus induction and plant regeneration, respectively. Regenerated plants were grown normally when shoots transplanted to the soil. A rapid and efficient plant regeneration system established in this study will be useful for molecular breeding of turfgrass through genetic transformation.

Background: Eruptive pseudoangiomatosis (EPA) is acute, self-limiting dermatosis characterized by the sudden onset of bright red angioma-like papules often surrounded by pale halo. The pathogenesis of EPA is still unknown, but insect bites, especially mosquito have been proposed as a potential causative factor of the disease. Objectives: To clarify the relationship between mosquito bites and EPA after analyzing seasonal variation in the incidence of EPA. Methods: We retrospectively analyzed the clinical data of 55 patients with EPA at Pusan National University Hospitals (Busan and Yangsan) from 2005 to 2016. Results: Forty-eight (87.2%) of 55 patients were diagnosed as EPA in autumn (25/55, 45.4%), and summer (23/55, 41.8%). Seventeen patients (30.9%) admitted the history of mosquito bites. EPA incidence in autumn showed the tendency to increase and reached the peak in 2016. Interestingly, according to the press release, mosquito population in the autumn is increasing steadily. Conclusion: Though more studies are needed to elucidate clear relationship between EPA and mosquito bite, mosquito bite could be the very causative factor of EPA based on the result of this study.
