  • 태생적으로 디지털 게임은 플레이어의 관심과 흥미를 끌고 몰입을 유도하기 위해 한 개 이상의 재미 요소를 포함하고 있다. 재미의 요소로는 경쟁과 퍼즐, 인터랙션과 역할놀이 등 다양하다. 본 논문에서는 디지털 게임의 재미 요소의 본질을 바흐찐의 카니발리즘 이론으로 해석해보고자 한다. 축제와도 같은 디지털 게임을 즐기는 플레이어들은 장소와 지속성에 의해 일상적인 삶과 게임을 구분한다. 또한 게임을 진행하는 동안 죽음과 부활을 반복하면서 재생되는 생명력을 경험하며, 시시각각 변화하는 캐릭터의 모습이나 인터페이스의 전복으로 인해 일상으로부터의 일탈을 경험하며 웃음을 생산해낸다.

  • 본 연구는 한국산 도롱뇽 유생(Hynobius leechii)을 대상으로 간접적인 카니발리즘 경험이 표현형에 어떠한 영향을 미치는지 알아보기 위하여 2011년 3월부터 4월까지 수행되었다. 우리는 유생의 생활사 초반에 개체 주변에서 발생하는 동종의 카니발리즘(간접적인 카니발리즘 경험)을 통하여 나타날 수 있는 폴리페니즘에 대하여 조사하였으며, 폴리페니즘의 발생 요인을 알아보기 위하여 간접적인 카니발리즘을 경험하는 그룹과 그렇지 아니한 그룹으로 나누어 실험하였다. 두 그룹의 도롱뇽 유생의 머리 중 가장 넓은 곳의 길이(LHW), 눈이 있는 부분의 길이(HWE), 코끝부터 항문(SVL)까지의 길이를 측정하였다. 또한 HWE를 LHW로 나누어 비율을 구한 후 통계처리를 하였다. 그 결과 유생의 생활사초반에 간접적인 카니발리즘에 노출될 경우 그렇지 못한 그룹보다 머리크기의 비율(HWE/LHW)이 의미 있게 증가하는 것을 볼 수 있었다. 이러한 결과를 통하여 도롱뇽유생은 주변의 다른 개체들로부터 전달되는 화학신호에 민감하게 반응하는 것을 알 수 있었다.

  • 시각적 공포요소가 등장인물과 직접적으로 대치하고 물리적으로 영향을 끼치는 것과 달리 비가시적 공포요소는 암시와 상상을 통해 표현되며 그 실체가 드러나지 않는다. 비가시적 공포요소가 실체를 드러내기 위해서는 '디아더스'와 같이 공포의 주체와 피해자의 관계가 전복되거나, '해프닝'과 '파라노말 액티비티'에서처럼 신체강탈이라는 방법으로 표현된다. 관계의 전복은 갑작스러운 성격의 변화를 야기하고, 신체강탈은 타인의 신체를 취한다는 점에서 식인행위와 연결된다. 식인행위와 성격의 변화는 카니발리즘에서 따르는 하위질서의 공식화와 비논리성에 속하는 것이다. 영화에서 나타나는 비가시적인 공포요소가 지니는 의미는 유토피아적 자유의 영역으로 들어간다는 카니발리즘의 본래의 의미와는 상반되어 보이지만 역할을 뒤집어 공포로 인한 갈등과 긴장이 해소되고 공포로부터 해방된다는 면에서 볼 때, 카니발의 정신인 '자유의 영역'으로 들어간다는 것과 의미가 상통할 것이다. 저자는 본 연구에서 비가시적 공포요소가 나타나는 영화의 표현과 플롯이 카니발리즘과 어떠한 관계를 가지는지 분석해 보려고 한다.

  • To investigate whether the rearing environmental factors (size heterogeneity, rearing density, and feeding frequency) affect the growth and cannibalism of fry in cultured puffer Takifugu obscurus, we conducted three experiments. To examine size effects, we used small (total length [TL] $26.0{\pm}0.5\;mm$, body weight [BW] $0.18{\pm}0.01\;g$), medium (TL $23.1{\pm}0.1\;mm$, BW $0.28{\pm}0.01\;g$), large (TL $26.0{\pm}0.2\;mm$, BW $0.48{\pm}0.01\;g$) and small-large size combination groups. For density, we used size-matched puffers (TL $25.0{\pm}0.5\;mm$, BW $0.53{\pm}0.03\;g$) and five density were examined ranging from 1.43 to 7.14 individuals/L. For the feeding frequency, we also used size-matched fry and feeding frequencies of three times/2 days, one time/day, two times/day, three times/day. We ran each experiment in triplicate and investigated the survival rate, daily food intake (DFI), feed efficiency (FE), and daily growth rate (DGR). The growth of the puffers increased with increasing size, density, and feeding frequency, while cannibalism increased with a greater size gap, density and lower feeding frequency. Therefore, we concluded that size, rearing density, and feeding frequency are major factors influencing growth and cannibalism of the puffer, T. obscurus.

  • Background: Mice are widely accepted research models of great clinical significance. Maintenance of laboratory mice breed is an essential aspect for performing research activities in various fields of science. Infanticide is one of the prominent causes of litter loss during maintenance of laboratory mice stock. The present study is an effort to monitor the effect of change in ambient temperature of female mice below the normal range on cannibalism and infanticide during early postparturition phase. Adult female Swiss albino mice have been divided into two groups of control and treatment. On the day of litter group one was maintained under controlled temperature conditions (minimum $20^{\circ}C$ to maximum $23^{\circ}C$) throughout, while female mice belong to group two have been exposed to variation of room temperature (maximum $15^{\circ}C$ to minimum $10^{\circ}C$ for two nights and one day) until 36 h postparturition. Results: The effects of temperature changes were observed on the infanticide behaviour of dams along with the survival of pups in early postparturition phase till 36 h after delivery. The significant statistical difference (P < 0.05) was reported in infanticide behaviour of dams when control and treatment group was compared. It is observed that decrement in surrounding temperature promotes decrement in the ambient body temperature of dams during early postparturition. It is proposed that alteration of hypothalamic homeostasis due to temperature change induces cannibalism and infanticide behaviour. Lack of thermoregulation during early postparturition creates the sense of insecurity, in-satiety, anxiety and stress. Conclusions: Authors strongly recommend the maintenance of body and surrounding temperature to prevent infanticidal behaviour and cannibalism within Swiss albino mice population. Further investigations are advisable to authenticate the active behavioural and biochemical pathway behind the phenomena.

  • Cannibalism plays important roles at the levels of both individual and population. To enhance overall rate of successful survival and reproduction, salamander larvae may have evolved to consume both conspecifics and heterospecifics. Consuming conspecifics could result in decreased inclusive fitness possibly by killing relatives. In several salamander species, discrimination of salamander larval siblings from non-siblings and heterospecifics to avoid such a risk has been reported. To determine whether the Korean salamander larvae consume non-siblings more often than siblings and to analyze prey preferences of the salamander larvae in several different experimental conditions, a series of foraging experiments was conducted in the laboratory. We found that 1) large cannibal larvae preyed on small sibling more often than small non-sibling in a mixed group of sibling and non-sibling, 2) cannibal larvae prefered to consume live, weak, and small larvae to dead, healthy, and large larvae, and 3) cannibal larvae consumed heterospecific tadpoles more often than conspecific nonsibling larvae in a mixed group. In addition, the larval density was positively correlated with the occurrence of spacing behavior, one of the agonistic predator behaviors among salamander larvae.

  • A review was undertaken to obtain information on the range of beak-trimming methods available or under development. Beak-trimming of commercial layer replacement pullets is a common yet critical management tool that can affect the performance for the life of the flock. The most obvious advantage of beak-trimming is a reduction in cannibalism although the extent of the reduction in cannibalism depends on the strain, season, and type of housing, flock health and other factors. Beak-trimming also improves feed conversion by reducing food wastage. A further advantage of beak-trimming is a reduction in the chronic stress associated with dominance interactions in the flock. Beak-trimming of birds at 7-10 days is favoured by Industry but research over last 10 years has shown that beak-trimming at day-old causes the least stress on birds and efforts are needed to encourage Industry to adopt the practice of beak-trimming birds at day-old. Proper beak-trimming can result in greatly improved layer performance but improper beak-trimming can ruin an other wise good flock of hens. Re-trimming is practiced in most flocks, although there are some flocks that only need one trimming. Given the continuing welfare scrutiny of using a hot blade to cut the beak, attempts have been made to develop more welfare friendly methods of beak-trimming. Despite the developments in design of hot blade beak-trimmers the process has remained largely unchanged. That is, a red-hot blade cuts and cauterises the beak. The variables in the process are blade temperature, cauterisation time, operator ability, severity of trimming, age of trimming, strain of bird and beak length. This method of beak-trimming is still overwhelmingly favoured in Industry and there appears to be no other alternative procedures that are more effective. Sharp secateurs have been used trim the upper beak of both layers and turkeys. Bleeding from the upper mandible ceases shortly after the operation, and despite the regrowth of the beak a reduction of cannibalism has been reported. Very few differences have been noted between behaviour and production of the hot blade and cold blade cut chickens. This method has not been used on a large scale in Industry. There are anecdotal reports of cannibalism outbreaks in birds with regrown beaks. A robotic beak-trimming machine was developed in France, which permitted simultaneous, automated beak-trimming and vaccination of day-old chicks of up to 4,500 chickens per hour. Use of the machine was not successful because if the chicks were not loaded correctly they could drop off the line, receive excessive beak-trimming or very light trimming. Robotic beak-trimming was not effective if there was a variation in the weight or size of chickens. Capsaicin can cause degeneration of sensory nerves in mammals and decreases the rate of beak regrowth by its action on the sensory nerves. Capsaicin is a cheap, non-toxic substance that can be readily applied at the time of less severe beak-trimming. It suffers the disadvantage of causing an extreme burning sensation in operators who come in contact with the substance during its application to the bird. Methods of applying the substance to minimise the risk to operators of coming in contact with capsaicin need to be explored. A method was reported which cuts the beaks with a laser beam in day-old chickens. No details were provided on the type of laser used, or the severity of beak-trimming, but by 16 weeks the beaks of laser trimmed birds resembled the untrimmed beaks, but without the bill tip. Feather pecking and cannibalism during the laying period were highest among the laser trimmed hens. Currently laser machines are available that are transportable and research to investigate the effectiveness of beak-trimming using ablasive and coagulative lasers used in human medicine should be explored. Liquid nitrogen was used to declaw emu toes but was not effective. There was regrowth of the claws and the time and cost involved in the procedure limit the potential of using this process to beak-trim birds.
