풍력발전단지가 급속히 증가함에 따라 풍력발전단지의 제어를 통한 계통 규정 참여가 중요해지고 있다. 본 논문에서는 풍력발전단지 내에서의 송전손실을 최소화하기 위한 풍력발전기의 제어 방식을 제안한다. 모의 계통은 덴마크 해상풍력단지 Horns Rev를 본떴으며 풍력발전기 별로 적용되는 풍속도 Wake Effect를 고려한 실제 데이터를 사용하였다. 손실 최소화를 위해 Linear Programming(LP)에 기반을 둔Optimal Power Flow(OPF)를 사용하였다.

Insulators of transmission line have been frequently damaged by lightning flashover. Arcing horns have been installed on string sets to protect insulators from the flashover. But reclosing number can be increased by the decrease of insulation strength and they are worrying it. Then this paper analyzes the installation effects of the arcing horn.

Two postmortem male and female reticulated giraffes were examined. The adult male giraffe showed sigmoid flexure of penis similar to most ungulates. Epididymis was well-developed and divided with head, body and tail parts. On the tip of penis, there was a urethral process. At the necropsy of a 20-month-old and nulliparous giraffe, ovaries, oviducts, two uterine horns with a septum and a cervix were distinctively shown. Understanding reproductive organs of giraffes would be beneficial to succeed in artificial breeding on this species especially in the difficult situation of importing hoofed animals.

A retrograde intravenous regional anesthesia was applied to the extremities of 30 cows, which was showed that mean value of induction time was 13.5 seconds, duration time 74.4 minutes, frequency of injection until to keep needle into the vein 1.27, and didn't observed local and systemic complications. Under the retrograde intravenous regional anesthesia, it was possible for surgical treatment of 20 cows with various foot disorders, to resect soft tissues of extremities and claw horns, to sexarticulate 2nd phalanx without pain reactions.

The subfamily Dynastinae generally exhibits strong dimorphism among males. However, until recently, studies on dimorphism and allometry were limited to horns. Lycomedes is a neotropic genus that belongs to the subfamily Dynastinae and is restricted to the Andean region of Colombia, Ecuador, and Peru. Among the Colombian Lycomedes species, this study focuses on the L. reichei and allied species, which have been designated here as the L. reichei species group, that displays a dramatic allometry. Here, various morphological characteristics of the L. reichei species group were analyzed and an allometry was proven.

In cryopreserved rat embryos, survival rates obtained in vitro are not always consistent with the rates obtained in vivo. To determine the optimal conditions for in vivo development to term, rat embryos at the 4-cell, 8-cell and morula stages were vitrified in EFS40 by a 1-step method and transferred into oviducts or uterine horns of recipients at various times during pseudopregnancy. Vitrified and fresh 4-cell embryos only developed after transfer into oviducts of asynchronous recipients on Day -1 to -2 of synchrony, i.e., at a point in pseudopregnancy that was 1-2 days earlier than the embryos. However, although about half the vitrified embryos transferred into oviducts on Day -1 developed to term, only a minority of embryos transferred at later times did so, whether vitrified (10-34%) or fresh (24-33%), suggesting that this may not be the most suitable stage for cryopreservation. Very few 8-cell embryos, either vitrified or fresh, developed when transferred into oviducts on Day 0 to -0.5. However, when transferred into uterine horns, high proportions of vitrified 8-cell embryos (-63%) developed to term in reasonably synchronous recipients (Day 0 to -0.5) but not in more asynchronous ones (6%; Day-1). A majority of vitrified morulae also developed to term (52-68%) in a wider range of recipients (Day 0 to -1), the greatest success occurring with recipients on Day -0.5. Similar proportions of vitrified and fresh 4-cell embryos, 8-cell embryos and morulae developed to term when there was appropriate synchronization between embryo and recipient. Thus vitrification of preimplantation stage rat embryos does not appear to impair their developmental potential in vivo.

With the use of a rat surgical model, the ability of carboxymethylcellulose and ibuprofen in the reduction of abdominal adhesion was examined. Seventy seven female rats were randomly divided into 7 groups : (1) control, (2) 2% CMC, (3) 3% CMC, (4) ibuprofen 25mg, (5) ibuprofen 50mg, (6) combination of ibuprofen 25mg and 2% CMC and(7) combination of ibuprofen 50mg and 3%, CMC. Following induction of abrasion injuries on ileum, colon and both uterine horns with a surgical blads, the rats in groups (2), (6) were infused with 2% CMC solution singly or in combined Infection of 25 mg/kg of ibuprofen for three consecutive days, the rats In groups (3), (7) were infused with 3% CMC solution singly or In combined Injection of 50mg/kg of ibuprofen for three consecutive days. The rats in groups (4), (5) were injected only with 25 mg or 50 mg/kg of ibuprofen for three consecutive days. After 10 days the abdominal cavities were opened and the appearance of formed adhesion were graded. The changes of body weight, CBC and blood chemicals were also evaluated at 3, 6 and 10 days after operation. In ileum, the rats in the groups (2), (6) and (7) showed less adhesion formation. In colon, there were significant differences(p<0.05) in adhesion formation in all treated groups as compared to control. In both uterine horns, there were significant decrease(p<0.05) of adhesion formation in groups(2), (6) and (7) in comparison with other groups. The increasing rate of body weight was evident in group (3) and fibrinogen concentrations at 6 and 10 days revealed significant decrease (p<0.01) in group (7), whereas there was no consistent change in CBC and blood chemicals. Therefore, it can be sugested that the infusion of 2% CMC solution with or without the injection of 25 mg/kg of ibuprofen and 3% CMC solution with the injection of 50 mg/kg of ibuprofen are effective and safe following abdominal surgery,

A necropsy of a primiparous, 4-year-old, Himalayan tahr (Hemitragus jemlahicus) was performed in September 8, 2009. Typical appearances of ovaries, oviducts, uterine horns, cervix and caruncles were well shown. Five cervical folds were present in the cervix. Cervical opening can be reached in the length of less than 15 cm from the entrance of vagina. Development of two follicles was found in the left ovary even though breeding season of this species naturally starts in late November. The reproductive organs of a primiparous, 3-year-old, Corriedale sheep showed that differences in the length and morphological appearance of cervix exist between two species. Comparative understanding of reproductive systems in Himalayan tahr and Corriedale sheep could help advancing assisted reproductive technologies in feral goats.

An 8-year-old, female lionhead rabbit with clinical sign of hematuria and vaginal discharge with/without blood was submitted to a local animal hospital. On exploratory laparotomy, three round to oval masses were observed in both uterine horns. The lumen of uterus was severely obstructed and distorted because of massive neoplastic proliferation. Histopathologically, the uterine masses revealed papillary projections along with irregular glandular structures into the lumen. The neoplastic foci were composed of numerous irregular sized neoplastic glands originated from uterine glands. These neoplastic cells showed very strong invasive tendency to muscle layer, therefore emboli of neoplastic cells were located in lymphatics. According to immunohistochemistry, the tumor cells in uterine masses demonstrated strong positive signals for cytokeratin, but negative for vimentin. Based on the gross, histopathologic and immunohistochemical features, this case was diagnosed as uterine adenocarcinoma in lionhead rabbit.
