This paper presents a fault location algorithm of a single phase-to-ground fault on a parallel transmission line which contains a teed circuit. The method uses only the local end voltage and current signals. Zero sequence currents of other lines are calculated by distribution factors. Instead of zero sequence current, negative sequence current is used to remove the effect of load current and to calculate the voltage of a fault resistance. There are three distance equations in this algorithm. One of them is to calculate inner part fault location without teed circuit and another equation is for outer part fault location without teed circuit and the other is to calculate inner part fault location with teed circuit. Correct fault distance is selected by the condition of each solution. Extensive simulation studies using EMTP have verified that the proposed algorithm can calculate an accurate fault distance in spite of effects of various error sources.

This study was carried out to investigate in connection with seeding rate according to the fertilizer application method and water management in direct seeding on flooded paddy surface. The total nitrogen and chlorophyll contents was decreased as increasing amount of seeding. The total nitrogen and chlorophyll contents were high in the strong drainage methods than the custom water management. LAI and dry mater recording where the seeding amount will increase to the fertilizer application method it increases consequently were low tendency from the site which omits the omitted the top dressing at tillering stage. The number of panicles per square metre was increased according to amount of seeding, but the number of spikelets per panicle was decreased. When omitted the top dressing at tillering stage and increasing the amount of seeding, the rice yield was high and amount of seeding was 89 kg per hectare. The results indicate that increasing of seeding rate and omission of fertilizer application with strong drainage at tillering stage was to reduce field lodging degree, to economy of water culture and to save labor for fertilization.

This experiment is a quantitative experiment where insoluble Vitamins E and K are extracted from the yolk of the spawning which was fed by by-products of tangerine, carrot, or Japanese apricot. Finally the purpose is to raise contents of the insoluble Vitamins E and K inside the yolk of the spawning. The saponification method through α, α - dipyridyl was used to determine the content of Vitamin E. Diethyl dithiocarbamate assay was used to examine the content of Vitamin K. The contents of Vitamin E in egg yolks of chicken fed by by-products of tangerine, carrot, or Japanese apricot increased 2 - 3 times compared to control egg, while the contents of Vitamin K almost no changed. 본 실험에서는 감귤, 매실, 당근의 껍데기로 감귤박, 매실박, 당근박을 먹여 산란계의 난황에 들어있는 Vitamin E와 K 함량을 높이고자 했다. Vitamin E 추출방법에는 검화방법인 α, α -dipyridyl에 의한 비색정량법을 사용하였으며 전처리 과정 중 석유 ether를 가하여 층을 분리하는 과정과 증류수를 가하여 층을 분리하는 과정에 있어서 신중을 가하였고 신속한 시료 전처리과정이 요구되었다. Vitamin K 추출에는 Diethyl dithiocarbamate에 의한 방법이 사용되었다. 실험결과 일반난황에서의 Vitamin E 함량보다 실험난황에서의 Vitamin E 함량이 2배 이상 높아졌음을 알 수 있었던 반면 Vitamin K의 함량은소량 증가하여 큰 변화가 없었다. 위의 결과를 통해서 난황에 이전된 Vitamin E의 종류가 무엇이며 어떠한 형태의 Vitamin E가 이전이 많이 되었는지를 확인하는 실험이 필요할 것이다. 이러한 추가적인 실험이 이루어졌을 때 상업적으로 이용한 가치가 있는 가를 고려하여야 할 것이다.

권희용,송승준,최재우,이인행,황희융 안양대학교 자연과학연구소 1998 自然科學硏究 Vol.5 No.1

본 논문에서는 축약 분산 기억 장치(Sparse Distributed Memory, SDM)를 사용한 신경망 호 수락 제어(Call Admission Control, CAC)를 제시한다. 호 수락 제어는 ATM 망 트래픽 제어의 핵심 요소이다. 이것은 ATM 네트워크 환경의 다양한 변화와 빠른 변화에 적응적이어야 한다. 기존의 ATM 호 수락 제어 방식은 가능한 모든 망 분석을 요구한다. 따라서 최적의 설계는 어렵다. 최근 신경망 방식이 이러한 문제를 해결하기 위해서 도입되었다. 그러나 이것 역시 적응적 제어를 제공하지 않았다. 이것은 부가적인 학습 데이터 테이블과 학습 기간을 요구하였기 때문이다. 우리는 CAC 기능 구현에 더 현실적인 SDM을 기반으로 한 신경망 호 수락 제어 방법을 제안하고, 이것을 기존의 신경망 호 수락 제어 방법과 비교했다. 제안된 방식은 급격한 변화에 적응적인 호 수락 제어를 제공한다. 실험 결과 SDM은 별도의 학습 테이블과 싸이클을 필요로 하지 않아, 빠른 적응력과 안정성을 가짐을 확인할 수 있었다. In this paper, we propose a Neural Call Admission Control(CAC) method using a Sparse Distributed Memory(SDM). CAC is a key technology of ATM network traffic control. It should be adaptable to the rapid and various changes of the ATM network environment. Conventional approach to the ATM CAC requires network analysis in detail in all cases. So, the optimal implementation is said to be very difficult. Therefore, neural approach have recently been employed. However, it does not meet the adaptability requirements. Because it requires additional learning data tagles and learning phase during CAC operation. We have proposed a neural network CAC method based on SDM that is more actual than conventional approach to apply it to CAC. We compared it with previous neural network CAC method. It provides CAC with good adaptability to manage changes. Experimental results show that it has rapid adaptbility and stability without additional learning table or learning phase.

The explosive growth of the internet traffic has imposed tremendous stress on routers, particularly, in the core network. Today's IP services reflect the unpredictable and undifferentiated packet loss and jitter characteristics of traditional best-effort routers. For above requirements, it is required not only the high-speed transmission of the packet, but the new routing function, the guarantees of QoS and bandwidth, the supports of user-requested services MPLS is proposed by the IETF and many other research institute as the solutions for this problem. In this paper, analyze performance of QoS Model applied RSVP over DiffServ to MPLS network. this model is each RSVP applied access network and DiffServ applied core network. In Result, It is amiss that basis MPLS net uses to core network because the average packet loss rate and average delay time are increased if traffic increases. Experiment result was seldom difference in case of network that apply each RSVP, DiffServ, RSVP over DiffServ. RSVP over DiffServs case packet loss rate and delay time were low than DiffServ and the packet loss rate is high because comparing than RSVP but delay time was very low.

소형환편기의 자동화기술을 위해 편환을 이동시킬 수 있는 편침과 cam을 편환이송용 장치를 고안하였다. 위편기의 편환이송 mechanism을 해석하고 소형환편기의 물리적 모사를 통해 편침과 cam의 형상을 최적화하였다. 편환이송장치를 사용하여 편물에 다양한 조직을 편성할 수 있는 편기의 개발이 가능하도록 하였다. The latch needle and cam are newly designed and manufactured to transfer the loop for automation of small circular knitting machine. The loop transfer mechanism is analized by the simulation of needle motion on the V-bed flat knitting machine to which optimum designed cam is attached. This loop transfer mechanism can be applied to small circular knitting machine for automation and variable knitted structure.

흡착특성이 다른 내분비계 장애물질 3종, Amitrol, Nonylphenol, Bisphenol-A의 GACs에서의 흡착 특성

최근주,김상구,권기원,지용대,김승현,김창원 한국물환경학회 2004 한국물환경학회지 Vol.20 No.3

Adsorption characteristics of three endocrine disruptors, amitrol, nonylphenol, and bisphenol-A, were evaluated depending on the type and service duration of activated carbon (AC). Bituminous coal-, wood-, and coconut-based coals were tested. Bituminous coal-based AC (BCAC) had the greatest sorption capacity for the three chemicals tested, followed by wood-based AC (WAC) for nonylphenol and coconut palm-based AC (CAC) for bisphenol-A. During the column test, amitrol removal efficiency increased over time, indicating that hydrophilic endocrine disruptors are biodegraded in the AC column. Removal efficiencies of hydrophobic compounds such as nonylphenol and bisphenol-A decreased over time since the main removal mechanism was adsorption. The order of the amitrol removal was: BCAC-5.9 yr , CAC-3.1 yr > BCAC-2.2 yr > BCAC-virgin > CAC-virgin > WAC-virgin > WAC-3.1 yr. In general, used AC had greater removals than virgin AC. The order of the bisphenol-A removal was: CAC-virgin > BCAC-2.2 yr > CAC-3.1 yr > WAC-virgin > BCAC-5.9 yr > WAC-3.1 yr. The order of the nonylphenol removal was: BCAC-virgin > WAC-virgin > CAC-3.1 yr ,WAC-3.lyr> BCAC-2.2 yr > BCAC-5.9 yr > CAC-3.1 yr. Bituminous coal AC performed the best over time. Endocrine disruptors such as these three compounds appear to be removed effectively by activated carbon through biodegradation and adsorption. Wood and coal based among the virgin ACs and 3.1 years used wood base among the used ACs appeared the lowest carbon usage rate(CUR) for nonylphenol removal by prediction model. Virgin and used coconut base ACs except BCAC had the lowest CUR for removal Bisphenol-A. Biodegradation of nonylphenol and Bisphenol-A did not occurred during the 9,800 bed volume experiment period. BCAC had the highest biodegradation capacity of 46% for amitrol among virgin ACs and the used coal based ACs had 33-44% higher biodegradation capacity than virgin's for amitrol so biodegradation is the effective removal technology for hydrophilic material such as amitrol.

최창혁,권굉우,김신근,이상욱,신동규,이승진 대한골절학회 2002 대한골절학회지 Vol.15 No.4

목 적 : 수술적으로 치료한 3분, 4분 상완골 근위부 골절을 외반형과 내반형으로 재분류하여 임상적 결과를 비교하고자 하였다. 대상 및 방법 : Neer 분류상 3분, 4분 상완골근위부 골절로 분류된 21례에 대해 수술적 치료를 시행하고 12개월 이상 추시된 증례를 대상으로, 골절부위의 각형성, 상완골두의 방향성, 그리고 우세 전위결절의 양상에 따라 외반형과 내반형으로 재분류하여 UCLA shoulder rating scale에 따른 기능적 평가를 시행하였다. 결 과 : 단순 방사선 소견을 기준으로 Neer의 3, 4분 상완골 근위부골절을 외반형과 내반형 및 각각의 아형(subtype)으로 분류할 수 있었다. 견관절 반치환술을 시술한 2례를 제외하고 분석한 각 그룹의 UCLA 기능적 평가는 외반형에서 양호 이상의 결과가 9례중 8례(89%), 내반형에서 10례중 4례(40%)로 외반형에서 더 우수한 임상적 경과를 보였다. 결 론 : 상완골 근위부 골절에서 골두의 방향성은 골절의 각형성 및 우세 전위결절의 양상과 높은 상관관계를 가졌으며, 내반형의 경우 혈행과 신경장애가 좀더 빈번하고 예후도 불량한 것으로 나타났고, 이러한 경우 수술시 도달 방법, 연부조직 상태에 대한 평가가 더욱 신중하게 고려되어야 할 것으로 생각되었다. Purpose : We reclassified three-and four-part proximal humerus fracture by Neer's classification into valgus & varus type, and compared the results of these groups. Materials & methods : 21 cases classified as three- and four-part fracture in Neer's classifiation were treated surgically and followed for 12 months. We reclassified the 21 cases vlagus and varus type fractures, according to angulation of fractures, facing of humeral head, and dominant displaced tuberosity. Functional evaluation was done by UCLA shoulder rating scale. Results : Neer's three- and four-part proximal humerus fractures could be reclassified based on angulation, facing of humeral head, and dominant tuberosity displacement. The functional results according to UCLA shoulder rating scale were good or excellent in 8 of 9 cases of valgus type(89%), and at 4 in cases of varus type(40%). The clinical result of the valgus type was better than that of the varus type. Conclusion : Based on reclassification system of proximal humerus fractures, clinical results and radiographic findings including angulation, facing of head and domonant tuberosity displacement showed close relationship. Neurovascular complication were more frequent in the varus type. Therefore, careful evaluation including surgical approach and soft tissue status should be considered in the varus type of complex proximal humerus fracture.
