  • Seasonal fluctuations in density of mosquito species were investigated at two cow sheds near to a large, reedy marsh with fairly polluted brackish water near the coast of Yongam-ri, Cheongryang-myon, Ulsan, Korea. Female mosquitoes were collected biweekly using Nozawa light traps from March to September, from 1999 to 2001. On average, 4,416.1, 5,505.9 and 6,863.8 females per trap night were collected from 10 species in 5 genera in 1999, 2000 and 2001, respectively. Among them, An. sinensis was most abundant (53.4% in species ratio), followed by Cx. tritaeniorhynchus (43.0%), Cx. inatomii (1.6%), Ochlerotatus dorsalis (1.3%) and Cx. pipiens pallens (0.5%). A malaria vector, An. sinensis and a Japanese encephalitis vector, Cx. tritaeniorhynchus were collected 3,663.3 females and 3,142.5 females per trap night from June to September for the years, respectively. According to the biweekly population changes at the area, Cx. inatomii which was dominant species in 1997, was the most abundant in the early July during 1999-2001.

  • This essay explores Louise Erdrich's politically resistant voice which interrogates and disrupts the long-lasting, pernicious misbelief about Native Americans as 'vanishing people'. This essay chiefly focuses on the two female characters-Lulu Nanapush and Marie Lazarre Kashpaw-in the author's widely acclaimed novel Love Medicine (1993). First, illustrating the Chippewas' multifaceted resistances against white Americans' colonialist dominance disclosed in their enforcement of governmental policy, law, religion, and culture, this essay investigates how Erdrich does not stop telling her story that the idea of 'vanishing people'-another version of 'Manifest Destiny'-is unfounded. Second, by referring to Freud's and Marcuse's speculation on 'Eros'-the great unifying energy that preserves all life-as an alternative to the predicament caused by an oppressive civilization, this essay illuminates Erdrich's vision of sustaining and regenerating the Chippewas' tribal life and heritage that center on the embracing power of love reified in Lulu and Marie. Their undying energy consolidating their communal love and ties, despite the destructive, oppressive colonialist milieu inflicted on the Chippewa Indian reservation, sheds light on the author's politics of 'Eros' predicated tightly upon her historical consciousness.

  • Economic injury levels (EILs) and economic control threshold (ET) were estimated for the Tea red spider mite, Tetranychus kanzawai Kishida(Acari, Tetranychidae) in Rubus coreanus Miquel. T. kanzawai density increased until the early-July and thereafter decreased in all plots except the non-innoculation plot where initial density of the mite were different each 0, 5, 10, 20 and 40 adults per plant branch on May 7 in 2008. And the occurrence of the densities were increased higher innoculated density than different innoculation density. The yield was decreased with increasing initial mite density and thereby the rates of yield loss was increased with increasing initial mite density. And T. kanzawai occurrence density, yields and the rates of yield loss, where initial density of the mite were different each 0, 2, 5, 10 and 20 adults per plant branch on May 8 in 2009 were similar tendency to 2008 year results. The relationship between initial T. kanzawai densities and the yield losses was well described by a linear regression, Y = 0.6545X + 3.0425 ($R^2$ = 0.93) in 2008, Y = 0.9031X + 2.0899($R^2$ = 0.96) in 2009. Based on the relationship, the number of adults per plant branch(EILs) which can cause 5% loss of yield was estimated to be approximately 3.0 in 2008 and 3.2 in 2009. And the ET was estimated to be approximately 2.4 in 2008 and 2.6 in 2009. The relationship between initial T. kanzawai densities and occurrence density of mid-May considering the best spray timing against T. kanzawai was well described by a linear regression, Y = 0.471X + 2.495($R^2$ = 0.95) in 2008, Y = 0.9938X + 3.1858($R^2$ = 0.96) in 2009. Based on the relationship, the number of adults per leaf(ET) in mid-May which can cause 5% loss of yield was estimated to be approximately 3.6 in 2008 and 5.8 in 2009.

  • 지난 1월 23일 한국농촌경제연구원(원장 이동필)은 서울 롯데호텔에서 농수축산인 관계자 1,500여명이 참석한 가운데 농업전망 2013 대회를 개최했다. 이날 발표된 육계전망 주요 내용을 발췌하였다. 종계 입식 마리수 증가로 2013년 육계 사육 마리수는 전년 대비 6.1% 증가한 8,740만 마리로 전망된다. 장기적으로 사육 마리수의 증가는 지속될 것으로 예상되나, 그 증가율은 점차 둔화될 전망이다. 또한 닭고기 공급은 전년 대비 증가할 것으로 예상되나 1인당 닭고기 소비량 증가로 산지가격은 소폭 상승할 것으로 예상된다. 2013년 육계 산지가격은 2012년보다 3.4% 상승한 1,754원/kg으로 전망된다. 이번 농업전망 발표가 빠른 환경변화에 신속히 대응하고 육계농장 경영에 도움이 되길 기대한다. 자세한 내용은 한국농촌경제연구원 홈페이지(http://www.krei.re.kr)에서 확인 가능하다.

  • 어군의 밀도를 음파로 추정할 때 어군의 총후방 산란 단면적이 어류개체의 후방 산란 단면적을 random phase로 합한 것과 같다는 가정에 대하여 실험적 검증을 시도하였다. 어체의 길이 대 음파의 파장비가 23일 때 두 마리와 세 마리의 숭어에 대하여 실시한 실험에서 전 산란각에 대한 편균이 random phase로 합할 때 보다 -1.7dB와 +1dB씩 편차를 보였다. 그러나 전체적으로는 in phase와 out phase sum 사이에서 변화함을 보였고, 최대오차는 in phase로 합해질 때로서 실제의 어군밀도 n에 비 해 최고 n\sup 2\에 이르기까지 추정 가능함을 실험결과는 보여주고 있다. 더욱이 이러한 결과는 어체간 의 간격변화에는 거의 무관하였으므로 소나무 빔폭이나 어군의 분포에 상관없이 빔폭 사이에 있는 어군 의 마리수에만 퐁후방 산란 단면적이 관계된다는 결론을 얻을 수 있었다.

  • Nine dogs presented to the Veterinary Medical Teaching Hospital of Konkuk University and Woosung Animal Hospital with a history of pelvic limb lameness. On physical examination, 9 dogs all showed a consistent weight bearing lameness and mild muscle atrophy. There was cranial drawer sign with pain in 9 dogs. Mediolateral radiographic projection revealed cranial subluxation of the tibial tuberosity in a tibial compression view. The right and left stifle joints were affected in 7 dogs and 2 dogs respectively. TightRope cranial cruciate ligament (CCL) technique for treatment of CCL deficiency was performed. Polyester and nylon were used to stabilize the stifle in 3 dogs and 6 dogs respectively. Suture sizes were 0.8 mm (n = 2), 0.9 mm (n = 4), 1.1 mm (n = 2), and $1.1mm{\times}2$ strands (n = 1) in diameter. Mean (${\pm}SD$) surgical duration was $48.3{\pm}8.5$ minutes (range 35 to 60 minutes). Preoperative and postoperative mean (${\pm}SD$) cranial drawer signs were $8.6{\pm}1.6$ mm (rage 7 to 12 mm) and $1.2{\pm}1.0$ mm (rage 0 to 3 mm) respectively. Immediate postoperative radiographs of the affected limb revealed no evidence of cranial subluxation of the tibial tuberosity in a tibial compression view of 9 dogs. Normal limb function was regained in 8 dogs within 8 weeks postoperatively. A consistent weight bearing lameness resolved in all dogs after TightRope CCL technique, but reoccurred in one dog (case No. 6) 2 weeks after surgery. Cranial subluxation of the tibial tuberosity was identified in a tibial compression test. During the second surgery, breakage of surgical button was identified and a tibial wedge osteotomy was performed. Based on surgical time, complication, stifle stability, and functional recovery, the present study indicated that TightRope CCL technique is effective treatment for the dogs with CCL deficiency.

  • Ark shell Scapharca broughtonii length and total weight growth by density, which was hanging-cultured near the sea area of Yeosu-city, Hoenggan-island (below is Yeosu), showed inverse correlation with density. As for the average growth of shell length by density, the test area of 10 shells showed the best result as 5.21 mm, and it became lower as density became higher. Also, the increase of total weight by density showed the same result, thus on the whole, the increase of average shell length and total weight of 10-20 shell test area showed the better result than the test area of 30-40 shells. In addition, even if the parashell's shell length by density and total weight growth in the sea area of Namhae-gun, Mijo-fishing port (below is Namhae) showed inverse correlation with density, it showed the slighter inverse correlation than the sea area of Yeosu. As for the average growth of shell length by density, the test area of 10 shells showed the best result as 4.55mm, but the average growth of shell length by density in the test area of 20-40 shells appeared to be similar as 3.11, 3.36 and 3.27 mm. On the other hand, as for the increase of total weight by density, the test area of 10-20 shells showed the more increase than the test area of 30-40 shells. In conclusion, it is guessed that the culture density of 20 shells/$0.12m^2$ (166 shells / $1m^2$) would be appropriate when hanging-culturing the shells. At the sea area of A, the survival rate of Scapharca broughtonii parashell was 68-87% by density respectively, and it showed the density-dependent result, while the survival rate of sea area of Namhae, where phytoplankton as prey is abundant, showed the much better result as 91-100%. It is guessed that this may be due to the fact that the quantity of phytoplankton in sea area of Yeosu is just 55.89% of sea area of Namhae. When hanging-culturing the shells, the water temperature by sea area ranged from 16.22 to $25.66^{\circ}C$, salinity 30.07-33.48, pH 8.10-8.45, and DO 4.49-9.65 mg/L.
