  • 2000년 10월부터 11월까지 일본 Aomori현 Mutu만에서 다섯동갈망둑, Pterogobius zacalles의 섭식행동에 관하여 연구를 실시하였다. 다섯동갈망둑은 돌 틈에서 펄과 함께 먹이를 채식하는 쪼기와 돌 표면에서 먹이생물을 흡입하는 두 가지 유형의 채식방법이 있지만, 주로 돌 틈에서 먹이를 채식하는 방법을 이용한다. 다섯동갈망둑의 두 가지 채식방법 모두는 먹이를 찾아 유영하는 찾기, 섭식장소에서 먹이생물을 발견하고 먹는 섭식, 섭식한 후에 먹이를 씹고 이물질을 뱉어내는 씹기의 3단계로 구성된다. 다섯동갈망둑은 두 가지 채식방법 중에서 돌 틈에서 섭식하는 쪼기를 이용할 때 더 먼 거리를 유영하여 먹이를 찾으며, 긴 시간동안 먹이를 씹는다. 다섯동갈망둑은 채식방법에 상관없이 단각류가 주요 먹이생물이지만, 돌 표면에서 채식하였을 때보다 돌 틈에서 채식하였을 때 상대적으로 크기가 큰 단각류나 십각류를 섭식한다. 이들은 돌 틈에서 먹이를 섭식할 때 더 많은 에너지와 시간을 소비하지만, 높은 칼로리의 먹이를 섭식한다. 따라서 먹이생물의 크기는 이들의 섭식방법을 결정하는 요인으로 사료된다.

  • At the time of host attachment, ticks are very sensitive to histamine, but during rapid blood sucking they paradoxically require histamine. Using a rabbit model, we studied the effects of histamine and antihistamine during attachment and fast-feeding in different life stages of Haemaphysalis longicorns. We examined how they responded to histamine and antihistamine by analyzing the detachment rate, histology of feeding lesions, and post-feeding behavior. A significant difference (P<0.01) was found in the detachment rate between experimental and control treatments throughout the observation period. Ticks exhibited a higher detachment rate (30.1%) at 12 h after histamine application during attachment time and on antihistamine-treated skin (25.4%) at 96 h during fast-feeding. After feeding on histamine-treated rabbits, the fully engorged body weights of larvae and nymphs were 0.7±0.36 mg and 3.5±0.65 mg, respectively. An average increase in body weight of 0.6±0.05 mg and 3.2±0.30 mg was observed for larvae and nymphs compared to the respective control weights. Nymphs and adults engorged after antihistamine treatment had an average body weight of 1.3±0.54 mg and 54±0.81 mg, respectively. An average decrease in body weight was observed in antihistamine-treated H. longicornis compared with control nymphs (3.3±0.42 mg) and adults (174±1.78 mg). Skin biopsies were collected after treatment, and differential histopathological characteristics were found between the treatment and control groups. Tick-infested skin collected from rabbits in the antihistamine-treated group lacked erythrocytes in the feeding pool, indicating that antihistamine impaired tick fast-feeding stage.

  • These studies aimed to determine how lighting might be used to improve feed intake and reduce aggressive behavior in newly weaned pigs. To examine whether this objective could be achieved an experiment was conducted to compare performance, behavior and body condition of weaners over 17-45 days, provided similar lighting quality (i.e. color temperature, color rendering index and lighting distribution) after weaning that piglets experienced prior to weaning. Triphosphor (TP) lighting to simulate daylight was provided during the day while at night, Pascal red (PR) lighting was provided to simulate the night-light piglets previously had received from infrared heating lamps. This treatment was compared to weaners provided conventional cool-white fluorescent light during the day only. Weaners on treatment lighting from 17-45 days of age showed no improvement in body weight or feed conversion at 24, 31, 38 and 45 days compared to the controls. There was, however, a significant improvement (p<0.05) in feed intake in the first week of weaning for weaners provided TP/PR lighting. Over the first 3 days of weaning, pigs on TP/PR lighting showed an increase (p<0.05) in the incidence of ear chewing but reduced (p<0.05) levels of nosing the abdomen of other pigs and reduced (p<0.05) occurrences of being stood on by other pigs. Females exhibited more (p<0.05) mounting and nosing behaviors and rubbing the heads of other pigs than males. On the other hand, males engaged in more (p<0.05) fighting, nipping, ear chewing and standing on other pigs compared to females. Pigs provided PR lighting on the first night of weaning engaged in higher (p<0.05) incidences of nosing and tail sucking behaviors, more (p<0.05) head thrusting, fighting and ear chewing compared to control pigs. The body condition of weaners provided the TP/PR lighting treatment was significantly poorer (p<0.05) compared to weaners on control lighting. In conclusion there was no improvement in production performance of weaners provided new technology lighting apart from the improvement in feed intake in the first week weaners were exposed to the TP/PR lighting.

  • 무당벌레(Harmonia axyridis)의 기본적인 행동학적 특성을 살펴보았다. 무당벌레는 먹이인 진딧물을 탐색할 때에 주로 작은턱수염을 이용하여 접촉감각에 의한 기주탐색을 하고 있다. 다른 한편으로는 무당벌레가 복숭아혹진딧물을 공격하게 되면 공격받은 진딧물 주위의 다른 복숭아혹진딧물은 근처의 잎으로 이동하거나 아래로 떨어져 도망하는 방어기작이 관찰되었다. 무당벌레가 먹이탐색을 위하여 이동하는 시간과 먹이를 잡고 섭식하는 시간은 무당벌레의 발육단계에 따란 현저한 차이를 나타내고 있었다. 무당벌레의 포식력을 조사한 결과 1일 평균 복숭아혹 진딧물은 약 120마리, 목화진딧물은 약 257마리를 섭식하였다. 오이 잎과 토마토 잎에 산란된 온실가루이 알은 무당벌레 3령충의 먹이로 제공하였을 경우 오이 잎에서는 2,420개, 토마토 잎에서는 2,750개의 알을 섭식하였으나, 진딧물을 제공한 무당벌레 유충과는 달리 정상적인 발육이 이루어지지 않았다.

  • Purpose: The aim of this study was to analyze Neonatal Intensive Care Unit nurses' behaviors while soothing newborns with bronchopulmonary dysplasia. Methods: An observational study was used to assess nurses' soothing behaviors. Data were collected from September, 2012 to March, 2013 using an audio-video recording system. Participants were eight babies and 12 nurses caring for those babies. After obtaining parental permission, the overall process of each episode from nurses' engagement in soothing to the end of soothing was recorded. Then a researcher interviewed each participating nurse. Data from 18 episodes were transcribed as verbal and nonverbal nursing behaviors and then categorized by two researchers. Results: There were 177 observed soothing behaviors which were classified with the five sensory-based categories (tactile, oral, visual, auditory, vestibular). Most frequently observed soothing behavior was 'Gently talking' followed by 'Removing irritant', and 'Providing non-nutritive sucking'. Nurses' perceived soothing behaviors were similar to the observed soothing behaviors except for 'Gently talking'. Conclusion: Nurses used diverse and mixed soothing behaviors as well as recognizing those behaviors as essential nursing skills. Nurses' soothing behaviors identified in this study can be used to comfort babies and to enhance their developmental potential in accordance with individual characterstics or cues.

  • Angelman syndrome(AS) is a rare genetic neurological disorder. The main clinical characteristics of this syndrome are delayed neuropsychological development, intellectual disability, speech impairment, jerky movements especially hand-lapping, frequent laughter or smiling. AS is a classic example of genetic imprinting in that it is usually caused by deletion or inactivation of genes on the maternally inherited chromosome 15. The syndrome has oral manifestations such as diastemas, tongue thrusting, sucking/swallowing disorder, mandibular prognathism, frequent drooling, and excessive chewing behavior. The purpose of this paper is to describe the interesting aspects of the dental treatment of a childe with AS.
