본 연구에서는 타이어의 저온 열분해 생성물 중 50% 이상을 차지하는 오일을 정제하여 등유등급의 물질규격에 적합한 자원화를 꾀하였다. 이를 위하여, 열분해 공정으로부터 얻은 유분 중 단증류 공정을 통하여 증류온도가 230 ℃와 400 ℃ 사이인 유분만을 취하였다. 얻어진 유분을 CoMo/γ-Al_2O_3를 촉매로 하는 수첨반응으로 처리하여 황, 질소, 산소, 그리고 존재할 수도 있는 다른 오염물질들의 함량이 KS M 2613의 등유품질규정에 적합하도록 낮추었다. 최종적으로 얻어진 유분 성분의 수율은 약 50% 정도였으며 그 품질은 한국산업규격의 품질검사 기준보다 월등히 우수했다. 이 연구에서 확인한 수첨반응의 최적조건은 압력 1000 psi, 온도 325 ℃, 반응시간 1 h이었다. The purpose of this study was to develop a recovery process of kerosene grade oil from the low-temperature pyrolyzed tire oil (PTO). In this effort, the fractions of boiling temperatures between 230 ℃ and 400 ℃ were collected via the batch distillation. In order to reduce the contents of sulfur, nitrogen, oxygen, and any other possibly existing contaminants to the values specified in KS M 2613, the fractions thus obtained were then subject to the hydrotreating process with the CoMo/γ-Al_2O_3 catalyst. The overall quality of the final products, especially content of sulfur, turned out to be far superior to that specified in the KS M standard. The optimum reaction conditions found in this work were as follows; 1000 psi, 325 ℃, and 1 h residence time.

이진헌(Jin-hun Lee),김승주(Seung-joo Kim),최승길(Seung-kil Choi),이주(Ju Lee) 대한전기학회 2007 대한전기학회 학술대회 논문집 Vol.2007 No.10

In previous structure of single phase LSPM, there is large torque ripple that makes a noise and a vibration by a distortion of flux distribution in air gap. By this reason, the single phase LSPM is not accepted home applications. So, in this paper, we propose new structure of single phase LSPM(Line Start Permanent magnet Motor). The proposed model is reduced a torque ripple about a half than previous model.

The purpose of This paper is the optimal design of a single-phase LSPM(Line-Start Permanent magnet Motor). A single-phase LSPM has a permanent magnet in the rotor that is same as induction motor. For that reason, the transient characteristics are very different from an induction motor. Therefore, we need the PM design to consider a transient and steady-state characteristics. In this paper, we designed a single-phase LSPM that has a high power and a good starting characteristics, and analyzed the performance of designed LSPM by varying each parameters. Finally, we examined and compared the simulation results and the prototype motor's characteristics.

가전분야에서의 전동기 효율향상을 통한 에너지 소비절감 효과는 상당히 크지만 이를 위한 전동기의 설계/해석 기술 확보가 아직은 미흡한 상태이다. 이에 따라 유도형 동기전동기가 제안되었지만, 유도형 동기 전동기는 유도전동기와 통기전동기의 특성을 동시에 가지고 있어, 해석 및 설계가 쉽지 않다. 따라서 본 논문에서는 기존의 냉장고 압축기용 전동기인 단상유도전동기를 대처할 수 있는 단상 유도형 동기전동기를 이용해 파라미터에 따라 특성이 어떻게 바뀌는가에 대해 서술하였다. 그에 따라 단상유도전동기의 정상상태 특성을 해석하고 제안모델의 성능을 기존모델과 비교하고 실험하여 해석결과의 신뢰성을 검증한다. 또한 본 논문에서는 제안모델의 기존 고정자 형상이나 권선 스팩을 유지하고 회전자의 형상이나 구조만을 변경시켜 성능향상을 도모하였다. 해석방법으로는 전자장 수치 해석적인 방법으로 널리 이용되고 있는 유한요소법(Finite Element Method : FEM)을 이용하였다. Electric motor efficient improvement from home appliance field is important to the effect reducing the energy consumption. But the electric motor design/analysis technology is still insufficient. Specially the electric motor design/analysis technology of satisfying characteristic of both the induction motor and the synchronous motor such as Line start permanent motor. Therefore the electric motor design/analysis technology is urgently demanded reliability. This paper proposes the sing1e-phase line-start permanent magnet motor to develop the motor it with be able to alternate the sing-phase induction motor it is a refrigerator compressor motor. The sing-phase induction motor is analyzed in the steady state. And we have a certification test to compare our single-phase line-start permanent magnet motor with the sing-phase induction motor. In order to improve the performance, the stator of the single-phase line-start permanent magnet motor is same as the stator of the sing-phase induction motor and changes the rotor form and has the permanent magnet. It used the Finite Element Method(FEM) which is widely used with electronic-magnetic field numerical analysis method.

김경수 ( Kim Kyung Su ),이진헌 ( Lee Jin Hun ),신진 ( Shin Jin ) 미래군사학회 2021 한국군사학논총 Vol.10 No.2

부사관은 "군사력의 중추"로 정의될 수 있다. 부사관이 전투력을 발휘하고 수행하는데 주력하는 반면, 장교는 전투력을 관리한다는 점에서 기인한다. 대부분의 전투는 중대급 이하에서 발생해 적과 직접 대치한다. 따라서 대부분 장교들은 계획을 수립하고, 부사관들은 소규모 부대장으로서 현장에서 병사들을 이끌고 전투력을 발휘한다. 현재 대한민국이 북한과 휴전 중인 것처럼 한반도에는 전쟁 가능성이 항상 존재한다. 또한, 부사관은 북한뿐만 아니라 다른 나라와의 다양한 전투 상황에서 소규모 부대 전투 지도자로서 역할을 수행해야 한다. 다만 부사관들의 현실을 고려할 때 미흡한 요소가 적지 않다. 예컨대 부사관에 대한 인지도와 처우가 부사관에 비해 열악하고 교육 수준도 떨어진다. 따라서, 부사관의 이력과 실상을 조사하고 발전방향에 대한 개선방향을 제시해야 했다. Non-commissioned officer can be defined as "The backbone of military combat power". It is due to the fact that non-commissioned officers focus on displaying and performing the combat power, while commissioned officers manage the combat power. Most of the combats occur at the company level or lower echelon, confronting the enemy directly. Therefore, commissioned officers mostly establish the plans and non-commissioned officers show the combat power as leaders of small units by leading the soldiers at the field. As Currently, Republic of Korea at an armistice with North Korea, there is always the possibility of war on the Korean Peninsula. Also, non-commissioned officers have to perform their roles as small unit combat leaders in various combat situations with not only North Korea, but also other countries. However, there are many insufficient factors, considering the reality of non-commissioned officers. For example, the recognition and treatment of non-commissioned officers are worse than the commissioned officers and the level of education is also deficient. Thus, the history and reality of a non-commissioned officer had to be investigated and the direction of improvement had to be provided to development direction.

N/A Objectives: Infection and replication of the hepatitis B virus are closely related to the host imm- unity. Anticancer chemotherapy decreases the immune response of the host, Especially, glucocorticoid can activate the replication of hepatitis B virus directly. It is well known that hepatitis B virus infection and hepatic complications are more common in patients with hematologic malignancies like malignant lymphoma. We studied the incidence of hepatitis B virus infection and hepatic complications following anti- cancer chemotherapy in patients with malignant lymphoma. Methods: Among 224 cases diagnosed as malignant lymphoma from January 1989 to December 1993 at Yonsei University Medical Center, 77 cases tested for hepatitis B virus serology was studied. Results: 1) Eighteen cases (23%) was HBsAg positive. 2) The results of hepatitis C virus serology in six cases were all negative. 3) Eight (57%) of 14 follow-up cases had hepatic complications, Two patients had fulminant hepatitis, two nonicteric hepatitis and four icteric hepatitis. 4) Interferon-alpha was administered in three cases among the patients with hepatic complications. Loss of HBeAg was observed in one case and loss of HBsAg in another case. Conclusion: Serious hepatic complications can be occurred following anticancer chemotherapy in HBsAg-positive patients with malignant lymphoma. Therefore, we recommend that patients being considered as candidates for anticancer chemotherapy should routinely undergo serologic test for Hepatitis B virus. In addition HBsAg-positive patients with anticancer chemotherapy should be regularly monitored for hepatic injury. And with the careful use of steroid and interferon, prolongation of survival might be searched for these patients.
