Semiconducting V-VI compounds have many applications such as piezoelectric, thermoelectric, and photovoltaic fields. Electrochemical processes have many advantages including low-cost, rapid deposition rate, and ease of control their microstructure and crystallinity by adjusting electrodeposition parameters. In this work, we demonstrated cost-effective high throughput fabrication of unique hierarchical nanostructures. Bi-Te and Sb-Te were selected as proof of concept materials because they possess unique electrical and thermoelectric properties which lead to many potential applications including thermoelectric and sensors. More details will be presented.
This study investigates, analyzes, and summarizes Dansplantation techniques and methods through practical methodology centering on fieldwork in order to present effective planting methods for large trees that have important significance. The conclusions are as follows : 1. The transplantation process of a large tree generally consists of the stages of digging up a tree, manufacturing a carrier frame, loading the tee on a vehicle, transporting, transplanting the tree, installing a strut and maintaining and managing the new transplant. In addition, planting a tree on a mounted place includes the primary procedures of trimming out the root, and preparing for transplanting the tree on a mounted place, as well as the secondary work of trimming out the root, transplanting a tree on a mounted place, maintenance and management. 2. In order to decide on a transplantation method for a large-sized tree, a structure calculation has to be performed first. That is, one must calculate the weight of the tree and the allowable stress of the strut (H-beam, etc.) fhst and then decide on the upper method through computer modeling based upon this structural calculation. 3. As a result of the analysis of a transplanted tree using the life soil method, it was confirmed that large quantities of feeder roots had developed around the root within a short time after the transplantation. The life soil method has proven to be very effective for transplantation of large-sized trees. 4. As for the production method of an H-beam strut frame, it was found that the manufacturing process and disassembly process were simple and proper; therefore, the H-beam frame is an appropriate structure to be used in the transplantation of large trees. 5. The concavo-convex method, which consists of filling the life soil in the concavo-convex area around the root, was found to be a method that promotes the growth of feeder roots within a short period of time and saves the supply of water at the same time.
Public access to government information is a common interest in the democratic countries. In 1996, The Freedom Of Information Act(FOIA) was enacted in Korea. Above all the statute requires agencies to provide the fullest possible disclosure of information to the public. The Act also recognizes the legitimate need to restrict disclosure of some information. For example, agencies may withhold information classified in the interest of national defence or foreign policy and criminal investigatory files especially about Security Observation Act(SOA). But the problem of information list and vagueness of escape clause made agencies arbitrary decision. This Case 99Ku24276 is the model of arbitrary decision of Department of Law(Dept. of Law). A student who is studying law requested the files which are related with SOA. But Dept. of Law refused to disclose the records. The first reason is non-existing of Records, the second if the files were existing, they fell within FOIA's eight statutory exemptions. The law also provides judicial remedies for denied access to records. So the requester brought a suit against Dept. of Law Dept. of Law pretended to non-existing of the records. The FOIA of Korea provides that a requester may ask for records rather than information. This means that an agency is only required to look for an existing record or documents in response to an FOIA request. An agency is not obliged to create a new record to comply with a request. An agency is not required to collect information it does not have. Nor must an agency do research or analyze date for requester. So an agency tends to hide the records because an agency can be requested for existing records. But the pretense of Dept. of Law has revealed. Dept. of Law also argued that the requested files would harm national defence or foreign policy. The Act sets standards for determining which records must be disclosed and which records can be withheld. But the Argument of Dept. of Law had no reason. Ambiguity of exemption clause could make Dept. of Law Constitutional tort. The exemption does not have a minimal rationality test. This case shows that the Law has many problems. They can be remedied by amendment of the Act. We must make efforts to revise FOIA of Korea.
우리나라 국립대학은 매우 어려운 상황에 놓여 있다 기성회비가 위법으로 판결 받으면서 폐지될 위기에 있고 이로 인한 대학운영경비의 부족 문제가 발생할 수 있다. 또한 몇몇 대학에서 추천한 총장임용후보자에 대해서 교육부가 그 임명제청을 거부하면서 장기간에 걸친 총장공백사태가 발생하고 있다. 이러한 사건이 발생했음에도 쉽게 해결되지 못하고 있는 것은 고등교육의 공공성에 대한 해석이 다르기 때문이다 우리나라 고등교육을 보는 시각은 크게 두 가지 입장이 대립하고 있다. 하나는 신자유주의의 입장에서 고등교육의 구조를 조정하려는 입장이 있고 다른 하나는 공교육적 관점에서 고등교육을 재편하려는 입장이다. 신자유주의자들은 고등교육을 사유재로 보기 때문에 기성회비를 포함하여 대학 운영경비를 학생에게 전가시키려고 한다 대학총장도 상업적 관점에 충실한 CEO형 총장을 임명하길 원한다 반면 공교육론자들은 대학운영경비를 국가가 부담해야 한다고 본다 따라서 기성회비에 대한 국가부담을 강조한다 또한 대학총장도 대학자치의 원칙에 따라 대학구성원들이 실질적으로 결정하는 것이 타당하다고 본다. 이 글에서는 공교육적 관점에서 국립대학들이 당면한 기성회비 문제와 총장임용 후보자 임명제청거부사건에 대한 해법을 제시해 본다.
This paper describes a design and implementation of the DFR(Document Filing and Retrieval) system. one of applications of DOAM(Distributed Office Application Model) which is the international standard in ISO(International Standards Organization). On the basis of the international standard, the DFR system is implemented on SUN workstation and PC/386 with C language, and its implementation is verified by tracing the association descriptor and primitives of service elements when its operation is tested between client and server. The result of this study shows that the DFR system can be implemented on the basis of the international standard, and makes a contribution toward the establishment of functional standards for the DFR system.
For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.
