두당 돈방면적과 돈군의 크기 등 돼지의 사육환경 조건이 자돈의 성장과 행동에 미치는 영향을 구명하기 위하여 이유후부터 체중 30kg까지의 자돈을 총 18돈방에 300두를 공시하여 시험하였다. 사료급여는 습식급여로 하였으며 두당 돈방 면적은 0.18$m^2$, 0.23$m^2$ 및 0.30$m^2$로 하였고 돈군의 크기는 돈방당 15두, 20두 및 25두로 하였다. 일당증체량, 일당사료섭취량 및 사료요구율을 조사하였으며 자돈의 행동을 휴식, 섭취, 공격, 사회성 및 유희행동으로 나누어 조사분석하였으며 그 결과를 요약하면 다음과 같다. 1. 두당 돈방면적이 0.18$m^2$의 경우 사료섭취량은 많았으나(p<0.01) 증체량은 차이가 없고, 사료효율은 낮으므로(p<0.05) 두당 0.23$m^2$의 경우가 최적인 것으로 나타났다. 2. 돈군의 크기에 따른 자돈의 증체나 사료효율에는 차이가 없었으며 사료섭취량은 15두군이 가장 많았다(p<0.01). 3. 자돈의 두당 돈방면적은 행동에 크게 영향을 미치며 두당 돈방면적이 좁을수록 공격행동이 증가되었고, 휴식, 사회성 및 유희행동은 감소되었다(p<0.01). 4. 돈군의 크기는 자돈의 행동에 큰 영향을 미치지 않았으나, 유희행동은 돈군이 커질수록 감소되었다(p<0.01). 5. 자돈의 성장과 행동면에서 두당 0.23$m^2$의 돈방면적을 부여하고 20~25두 크기로 돈군을 유지하는 것이 최적인 것으로 나타났다.

두당돈방면적과 돈군의 크기 등 비기후적 환경요인이 육성돈의 생산과 각종 행동유형에 미치는 영향을 구명하기 위하여 체중 30kg부터 60kg까지의 육성돈을 18돈방에 총 270두를 공시하여 시험하였다. 두당돈방면적을 0.33$m^2$, 0.44$m^2$ 및 0.66$m^2$로 설정하였고 돈군의 크기는 12두, 15두 및 18두로 하였다. 증체량, 사료섭취량, 사료요구율 및 휴식, 채식, 공격, 사회성, 유희행동 등의 각종 행동유형을 조사하였으며 각 조사항목에 대하여 요인별로 주요인 효과와 자 요인들간의 상호작용 효과를 분석하였으며 그 결과를 요약하면 다음과 같다. 1. 두당 돈방면적을 0.44$m^2$로 한 것이 육성돈의 증체 및 사료요구율(p<0.01)면에서 가장 우수한 것으로 나타났다. 2. 돈군의 크기에 따라서는 15두군이 12두와 18두군에 비하여 증체와 사료요구율이 가장 우수한 것으로 나타났다(p<0.05). 3. 육성돈의 행동에 대한 두당돈방면적의 효과는 두당돈방면적이 좁아지면 휴식행동과 비공격적 사회성 친화 행동이 감소되나 섭취행동과 공격행동은 그 빈도가 증가되었다(p<0.01). 4. 돈군의 크기는 육성돈의 행동에 크게 영향을 미치고 있으며 돈군의 크기가 커질수록 육성돈의 공격행동과 섭취행동은 증가되나 휴식행동은 감소되었다(p<0.01). 5. 육성돈의 생산과 행동면에서 두당 0.44$m^2$로 하고 돈군의 크기는 15두로 하는 것이 최적조건인 것으로 나타났다.

Background: Colorectal cancer has several modifiable behavioural risk factors but their relationship to the risk of colon and rectum cancer separately and between countries with high and low incidence is not clear. Methods: Data from participants in the Asia Pacific Cohort Studies Collaboration (APCSC) were used to estimate mortality from colon (International Classification of Diseases, revision 9 (ICD-9) 153, ICD-10 C18) and rectum (ICD-9 154, ICD-10 C19-20) cancers. Data on age, body mass index (BMI), serum cholesterol, height, smoking, physical activity, alcohol and diabetes mellitus were entered into Cox proportional hazards models. Results: 600,427 adults contributed 4,281,239 person-years follow-up. The mean ages (SD) for Asian and Australia/New Zealand cohorts were 44.0 (9.5) and 53.4 (14.5) years, respectively. 455 colon and 158 rectum cancer deaths were observed. Increasing age, BMI and attained adult height were associated with increased hazards of death from colorectal cancer, and physical activity was associated with a reduced hazard. After multiple adjustment, any physical activity was associated with a 28% lower hazard of colon cancer mortality (HR 0.72, 95%CI 0.53-0.96) and lower rectum cancer mortality (HR 0.75, 95%CI 0.45-1.27). A 2cm increase in height increased colon and all colorectal cancer mortality by 7% and 6% respectively. Conclusions: Physical inactivity and greater BMI are modifiable risk factors for colon cancer in both Western and Asian populations. Further efforts are needed to promote physical activity and reduce obesity while biological research is needed to understand the mechanisms by which they act to cause cancer mortality.

Psychiatric disorder as dysfunctional behavioural syndrome is a paradoxical phenomenon that is difficult to explain evolutionarily because moderate prevalence rate, high heritability and relatively low fitness are shown. Several evolutionary genetic models have been proposed to address this paradox. In this paper, I explain each model by dividing it into selective neutrality, mutation-selection balance, and balancing selection hypothesis, and discuss the advantages and disadvantages of them. In addition, the feasibility of niche specialization and frequency dependent selection as the plausible explanation about the central paradox is briefly discussed.

A one-month old Holstein calf with clinical histories of diarrheal weekness and behavioural abnormality revealed clinical findings of anemia and dehydration. The red blood cells were $1.4{\times} 10^{6}/{\mu}l$ and packed red cell volume was 45%. A blood smear showed a large number of circulating Trypanosoma theileri. To treat Trypanosomiasisi the patient received once a daily oral dosage o$\ulcorner$ 10 mg/kg of the Quinidine sulfate including transfusion (200 ml) for 3 days. After 2 weeks, the calf recovered body condition. These results suggest that Administration of Quinidine sulfate in trypanosomiasis may be a useful treatment approach.

삼축압축시험의 결과를 이용해 2차광물성분을 많이 포함하고 있는 모앙이 편마암인 풍화잔적토의 압축 및 강도특성을 분석하여, 모암 및 광물성분비가 다른 기존의 연구결과와 비교하여 풍화잔적토의 모암과 광물성부네 따른 강도정수의 차이 및 거동특성을 파악하기 위한 근간을 제시하고자 본 연구를 수행하였으며, 치를 위하여 CIV, CID, CKoU, CKoD 등의 삼축압축시험을 실시하였다. 기원 및 광물성분이 다른 풍화잔적토라도 정규압축곡선(NCL)의 기울기는 유사한 양상을 보이며, 압축시 입자파쇄효과로 인하여 약 85%의 소성변형량을 나타냈다. 전단시 또이동 시료는 김천 및 안동 시료와는 다르게 응력연화현상을 나타내 기원 및 구성광물에 따라 다른 거동을 보여줌을 알 수 있었다. 펀단저항각은 시료가 석영과 장석성분 등의 1차 광물과 2차광물의 구성성 분에 따라 달라짐을 알 수 있었으며, 반면에 간극수압계수는 기원 및 광물성분을 막론하고 1 이상의 큰 값을 나타냈다.

The objective of the study was to investigate the effect of feeding fibrous diets on growth performance and occurrence of aggressive behaviours in growing pigs. Sixty healthy castrated pigs (initial body weight: $46.7{\pm}4.35$ kg) were used. A basal diet was diluted with maize cobs to two levels (0 and 160 g/kg dry matter). Behavioural activities were observed using video cameras for three weeks, 8 h/d starting at 0800 h. Pigs subjected to control diet gained more weight compared to pigs receiving fibrous diet in week 1 (0.47 vs 0.15 kg, respectively) and 2 (1.37 vs 1.04, respectively) (p<0.05). Average daily gain was not affected by treatment diet in the third week. Pigs on high fibrous spent more time eating, lying down, standing, walking and fighting (p<0.05) compared to pigs on control diet. Time spent eating increased as the weeks progressed whilst time spent lying down decreased. Time of day had an effect on time spent on different behavioural activities exhibited by all pigs on different treatment diet (p<0.05). Inactivity was greatest in 5th (1200 to 1300 h) hour of the day for all the pigs on different dietary treatments. Skin lesions appeared the most on neck and shoulder region followed by chest, stomach and hind leg region, and finally head region (p<0.05). Pigs on high fibre diet had more skin lesions in all body regions compared to pigs on control diet (p<0.05). It can be concluded that the high fibrous diet with maize cobs did not affect growth performance and also did not reduce aggressive behaviours. Aggressive behaviours emanated out of frustration when queuing on the feeder. The findings of this study suggest that maize cobs can be included at a level of 160 g/kg in diets of pigs. However, to reduce the level of aggression more feeding space should be provided.

The loss, alteration, and fragmentation of habitat have led to a reduction of biodiversity. The growing awareness of the negative effects of habitat fragmentation on natural systems has resulted in conservation strategy that is concerned with not only population and habitat level but also ecosystem and landscape level. Especially, ecological network to link core areas or major habitat patches is one of the most important issues. Recently, landscape connectivity is increasingly used in decision making for fragmented landscape management in order to conserve the biodiversity in the regional scale. The objective of this study was to find potential forest as a ecological corridor in Go-yang city, Gyung-gi province using cost-distance modelling method that can measure connectivity based on animal movement. 'Least cost-distance' modelling based on functional connectivity can be useful to establish ecological network and biodiversity conservation plan. This method calculates the distance modified with the cost to move between habitat patches based on detailed geographical information on the landscape as well as behavioural aspects of the animal movement. The least cost-distance models are based on two biologically assumptions: (1) dispersers have complete knowledge of their surroundings, and (2) they do select the least cost route from this information. As a result of this study, we can find wildlife moving route for biodiversity conservation. The result is very useful for long-term aspect of biodiversity conservation plan in regional scale, because this is reflection of geographical information and behavioural aspects of the animal movement.
