The network drafting is introduced by american weaver Alice schlein, that is not a new weave, but a way of exploring old structures and driving them a new design. It was evident that larger scale pattern design produced on computer dobby-that is a loom without a jacquard mechanism, draw harness, or other extra patterning devices. Therefore, this study explored that developing and new weave design through the processing of network drafting In give a guide based on it In this process, the results of this study were as follow. A network is a collection of legal threading position that is constructed from a building block, called an "initial" which is the smallest identifiable unit of the threading. The process of network drafting produces large-scale designs without the chunky look of block weaves in addition In infinite potential variation on a singles threading through changes in tie-ups and dobby peg plan. It can get various new drafting through using of isolated, connected, disconnected pattern line.

최근 3년 6개월동안, 재태 연령 37주 미만의 미숙아 동맥관 개존증 환아 10명에서 생후 평균 30일경 결찰술을 시행하여, 수술시 사망은 없었으며, 수술후 2개월간의 수술과 관계없는 만기 사망 1례를 제외한 나머지 9례 모두에서 2∼26개월의 추적관찰기간동안 양호한 경과를 보였기에, 중증의 증세를 보이는 미숙아 동맥관 개존증에 있어서 수술적 결찰술이 가장 근치적이고 유용한 치료법으로 생각되는 바이다.

This article is dedicated to present a cornerstone for a desirable legal structure in the area of the administration and utilization of the intellectual property rights of the university research results sponsored by the government, and, in the long run, contribute to the industrial development of our country. In order to achieve that purpose, this article reviews basic theories and current status of the intellectual property regime for the research results sponsored by the government, and presents some suggestions for a desirable legal institution, in particular, including that 'Intellectual Property Rights Administration Center', should be established, an exclusive institution for the systematic administration of the follow-ups of the research results with speciality.

This paper proposes about decentralized control approach based Leader-Follower formation control using LOS (Line of Sight) algorithm and unknown input observer. The position of robots which is a basic information in multi-robot or single robot motion control is determined by localization algorithm fusing UPS (Ultrasonic Position System) and kinematics model. For formation control, a decentralized control approach individually installing a local controller in leader and follower robot is adopted. Leader robot is controlled to track a specified trajectory by LOS algorithm, and the other robots follow the leader by local controller based on tracking platoon level function, self-sensing data and estimated information from unknown input observer. The performance of proposed method is proven through the formation experiment of two vehicle models.

A group of universities have come together with the aim of designing and developing Small Aperture Robotic Telescopes (SmART) for use by students to observe variable stars and transient follow-ups. The group is deliberating on the components of the robotic system; e.g. the telescope, the mount, the back-end camera, control software, and their integration keeping in mind the scientific objectives. The prototype might then be replicated by all the participating universities to provide round the clock observations from sites spread evenly in longitude across the globe. Progress made so far is reported in this paper.

A tooth with primary endodontic disease that demonstrates a periodontal defect might be extracted because of misdiagnosis as severe periodontal disease or a vertical root fracture. The aim of this case report was to demonstrate the long-term survival of endodontically treated teeth, which had been initially considered unsavable. With meticulous evaluation including the patient's dental history, clinical and radiographic examinations, teeth with primary endodontic lesions could be differentiated and saved after proper root canal treatment. Pain history, vitality test, and radiographic examinations, as well as a general periodontal condition check with periodontal probing on an affected tooth, might be the key methods to differentiate endodontic pathosis from that of periodontal disease.

During the last decade the role of minimally invasive surgery has been increased, especially with the introduction of the robotic system in the surgical field. The most important advantages of robotic system are represented by the wristed instrumentation and the depth perception, which can overcome the limitation of traditional thoracoscopy. However, some data still exist in literature with regard to robotic lobectomy. The majority of papers are focused on its safety and feasibility, but further studies with long follow-ups are necessary in order to assess the oncologic outcomes. We reviewed the literature on robotic lobectomy, with the main aim to better define the role of robotic system in the clinical practice.

Background: Reconstructing maxillofacial defects is quite challenging for most surgeons due to the region's complex anatomy and cosmetic and functional effects on patients. The use of pre-made alloplastic implants and autogenous grafts is often associated with resorption, infection, and displacement. Recent technological advances have led to the use of custom computer-designed patient-specific implants (PSIs) in reconstructive surgery. This study describes our experience with PSI, details the complications we faced, how to overcome them, and finally, evaluates patient satisfaction. Case presentation: Six patients underwent reconstruction of various maxillofacial defects arising due to different etiologies using PSI. A combined total of 10 implants was used. PEEK was used to fabricate 8, while titanium was used to fabricate 2. No complications were seen in any patient both immediately post-op and in subsequent follow-ups. All patients reported a high level of satisfaction with the final result both functionally and cosmetically. Conclusion: The use of computer-designed PSI enables a more accurate reconstruction of maxillofacial defects, eliminating the usual complications seen in preformed implants and resulting in higher patient satisfaction. Its main drawback is its high cost.

Ultra Metal-Poor (UMP; [Fe/H] < -4.0) stars are thought to be true second generation of stars. Thus, the chemistry and kinematics of these stars serve as powerful tools to understand the early evolution of the Milky Way (MW). However, only about 40 of these stars have been discovered thus far. To increase the number of these stars, we selected UMP candidates from low-resolution spectra (R ~ 2000) of the Sloan Digital Sky Survey (SDSS) and Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), and performed high-resolution (R ~ 40,000) spectroscopic follow-ups with Gemini/GARACES. In this study, we present chemical and kinematic properties of the observed UMP candidates, and infer the nature of their progenitors to trace the chemical enrichment history of the MW.

Patients with pediatric cancer often undergo multiple therapies, such as chemotherapy, radiation therapy, and stem cell transplantation. These treatments, while essential, can result in dental developmental issues, including hypodontia, microdontia, short roots, and delayed dental development. This report presents two cases of pediatric patients diagnosed with neuroblastoma who exhibited severe tooth mobility due to short roots as a complication of cancer treatment. Moreover, we investigated the conservative management of the patients' conditions using resin wire splints and orthodontic miniscrews for skeletal anchorage along with long-term follow-ups to evaluate their prognosis.
