This paper is about the development results of an automatic silkworm breeding system to reduce labor and time by automatically performing the works for silkworm droppings changing and feed its food. It consists of an automatic guided vehicle and a processing unit. The automatic guided vehicle transports a silkworm dropping changing frame mounted on a silkworm tray stand, and the processing unit takes over the dropping changing frame on it, removes excrement contained the droppings changing frame and feeds silkworm food. In the case of the current silkworm farming, because the breeding period for large silkworms (4 to 5 stage) is short to 14 days and the supply of mulberry leaves takes 98% of the total amount of mulberry leaves needed for breeding silkworms at this time, labor concentration is intensive, and all breeding works depends on manpower. Therefore, it was difficult to breed large silkworms on a large scale. Moreover, silkworms are bred by adding Silkworm bed (Seop) and mulberry in the silkworm tray, and their droppings changing is to separate silkworms and excrement by moving silkworm trays one by one, and the production cost increases due to the high-cost manpower for silkworm breeding. To solve this problem, technology for automating silkworm breeding has also been developed. However, there is still a limitation that silkworm feeding and droppings changing works are not suitable for mass breeding because a lot of labor and time are spent depending on manual work. Therefore, a new silkworm breeding system for breeding silkworm automatically is needed and so we developed an Automatic Silkworm Breeding System applying the droppings change frame, the inverting unit, the feeding silkworm food device and automatic guided vehicle.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare repoted case. Recently we experienced huge posterior mediastinal goiter with compressin of trachea in 57-year old male, The patient that complained of dyspnea referred to our hospital for further evaluation of mediasitnal tumor. We confirmed huge secondary posterior mediastinal intrathoracic goiter with diagnostic methods following by chest X-ray, thyroid scan, chest CT, and CT guided fine needle aspiration biopsy in this patient, and performed operation for excision Exision of posterior mediasitnal goiter performed through initial transeverse cervical incision and additional median sternotomy, and the mass removed completely without any complications. The postoperative course were uneventful.

Fine needle aspiration has been effectively being applided to pediatric tumors since it renders a rapid diagnosis with minimal intervention. This measure is especially required for the large pediatric mass, which needs preoperative chemotherapy or radiotherapy to shrink the tumor to an operable size. A case of neuroblastoma of mediastinum, stage IV diagnosed by CT-guided FNA is described.

흉부방선균증은 임상양상 및 방사선학적 소견이 폐의 기타 염증성 질환이나 악성암과 유사한 경우가 많아 감별진단에서 놓치기 쉬우나, 대부분 항생제 치료에 좋은 반응을 보이므로 조기진단을 위한 적극적 접근으로 심각한 합병증의 발생 및 불필요한 수술을 막아야 한다. 저자들은 폐암을 의심하여 시행한 검사도중 폐를 침범하는 방선균증을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

We report a case of a patient with locally advanced prostate cancer who had only lymph node involvement without bone metastasis on F-18 FDG PET/CT. A 62-year-old Korean male was admitted to our hospital due to dysuria. His PSA level on admission was 79.35 ng/mL. A transrectal ultrasound-guided prostate biopsy confirmed prostate cancer and his Gleason score was 10 (5+5). F-18 FDG PET/CT demonstrated a hypermetabolic mass lesion with SUVmax 7.0 in the prostate and hypermetabolism with SUVmax 4.7 of the abdominal and pelvic lymph nodes. Tc-99m HDP bone scan showed no significant bone metastasis. The patient underwent hormonal therapy for 9 months. Follow-up F-18 FDG PET/CT showed significantly reduced size and FDG uptake in the prostate and abdominal and pelvic lymph nodes. In this case, treatment monitoring with F-18 FDG PET/CT showed decreased mass size and FDG uptake in the prostate and abdominal and pelvic lymph nodes.

Pancreatic metastasis from malignant phyllodes tumor (PT) of the breast is rare, and only a few cases have been reported in the literature. Here, we report a case of pancreatic metastasis from malignant PT of the breast in a 48-year-old woman. She had had three episodes of recurrence of malignant PT in her right breast. She presented with epigastric pain for 2 months. Computed tomography and magnetic resonance imaging revealed a 6 cm-sized, well-defined, heterogeneous mass with peripheral enhancement in the body of the pancreas. Endoscopic ultrasonography-guided fine-needle aspiration was performed, and the pathologic report suggested spindle cell mesenchymal neoplasm. Subsequently, surgical excision was performed, and the mass was confirmed as a metastatic malignant PT. The imaging findings are discussed and the literature is briefly reviewed in this report.

A 10-year-old castrated male Schnauzer (case 1) and a 13-year-old intact male Schnauzer (case 2) was referred with mass of left hind limb. We performed hemogram, serum chemistry, radiography, ultrasonography, computed tomography, fine needle aspiration and histopathology. The complete blood counts and serum biochemistry results were within the reference range. Radiography showed cutaneous mass with soft tissue density. The lesions of two dogs were revealed a definite marginated hyperechoic mass with vascularization in ultrasonography. Computed tomography showed an isodense mass in the left hind limb region with minimal contrast enhancing in case 1 and heterogenous enhancement in case 2. Cytology from ultrasonographic guided aspiration of the mass was suspected fibrous tissue-derived benign cell in two dogs. A surgical excision was performed in two dogs. In histological examination of the resected mass, cutaneous fibroma was revealed. The two patients were successfully treated by surgery and postoperative care. This report decribes and compares radiographic, ultrasonographic, computed tomographic, cytologic and histopathologic features of the cutaneous fibroma of two schnauzer dogs.

목적: 근골격계 종물의 진단에 있어 초음파 유도하 생검의 유용성을 알아보고자 하였다. 대상 및 방법: 2002년 3월부터 2003년 8월 사이에 본원 정형외과를 내원한 환자 중 연부조직 종물을 가지는 환자의 진단을 위하여 조직 생검이 필요하였던 5 5명 환자를 대상으로 하여 전향적인 연구를 하였다. 조직검사는 초음파 유도하에서 조직의 채취 부위에 국소마취하에 시행하였으며 14 gauge 또는 18 gauge의 굵은 바늘을 사용하여 5~6개의 조직을 얻을때까지 시행하였다. 통계적인 분석은 임상적으로 치료가 가능하였던 11명의 환자와 수술적 절제 후 조직의 최종 확인이 가능한 38명을 포함하여 49명을 대상으로 하였다. 결과: 불충분한 조직을 얻은 경우나 조직학적 진단이 불가능한 6명의 환자를 제외하고 정확한 진단은 49명의 환자중 47명의 환자에서 얻을 수 있어 정확도는 96%였고 민감도는 90%, 특이도는 100%였다. 전체 55명의 환자중 89%(49명)에서 조직학적 진단이 가능한 충분한 조직을 얻을 수 있었다. 모든 환자에서 특별한 부작용은 없었다. 결론: 초음파 유도하 생검은 연부 조직 종물의 정확한 위치에 바늘을 위치시킬 수 있어 연부조직 종양의 진단이나 골종양의 진단에서 골외 부분이 있는 경우 시행할 수 있는 안전하면서 유용한 방법이라 생각된다.

The capitalization of know-how, knowledge management, and the control of the constantly growing information mass has become the new strategic challenge for organizations that aim to capture the entire wealth of knowledge (tacit and explicit). Thus, knowledge mapping is a means of (cognitive) navigation to access the resources of the strategic heritage knowledge of an organization. In this paper, we present a new mapping approach based on the Boolean modeling of critical domain knowledge and on the use of different data sources via the data mining technique in order to improve the process of acquiring knowledge explicitly. To evaluate our approach, we have initiated a process of mapping that is guided by machine learning that is artificially operated in the following two stages: data mining and automatic mapping. Data mining is be initially run from an induction of Boolean case studies (explicit). The mapping rules are then used to automatically improve the Boolean model of the mapping of critical knowledge.
