The slaughter of livestock is inevitably required to obtain meat products from livestock. Since slaughter means pain and death for animals, reducing the pain and distress of animals during slaughter is very important from a perspective of animal welfare based on the principle of respect for life. Generally, two stunning methods, CO2 stunning and electrical stunning, are used for slaughter. When the carotid arteries of the lungs are cut off for bleeding, the bronchial tubes are also severed. To determine the degree of blood inflow into the lungs through the severed bronchial tubes, the prevalence rates of pulmonary diseases and pulmonary congestion in slaughtered pigs were analyzed. In this study, the prevalence of pneumonia was 24.9% in Slaughterhouse A using the gas method, but it was decreased by about 10% to 15.7% and 12.6%, respectively, in Slaughterhouses B and C using the electric method. On the other hand, the prevalence of pulmonary congestion in Slaughterhouses A, B, and C was 4.24%, 14.10% and 16.40%, respectively. In other words, the prevalence of pulmonary congestion was higher by about 10% in the groups of pigs slaughtered by the electric method (Slaughterhouses B and C) than in the group of pigs slaughtered by the gas method (Slaughterhouse A). These results indicate that blood inflow into the pulmonary alveoli led to a diagnosis of pulmonary congestion instead of pneumonia in some pigs with pneumonia. In short, it was found that about 10% of pigs stunned by the electric method were not in a state of complete unconsciousness but in a partially conscious state during slaughter. It is suggested that slaughterhouses should be equipped with gas stunning equipment instead of applying the electric method due to lower costs.

계절에 따른 정원의 경관 변화 특성을 알아보고자, 우수 정 원 4개소를 대상으로 계절별 식재 특성과 색채 변화를 분석하 였다. 대상 정원에서 계절별로 조사된 식재 종수 합은 346분 류군이었고, 교목:관목:초본의 식재 백분율(%)은 8:21:71로 나 타났다. 초본은 봄을 기준으로 여름과 가을에 각각 6%와 15% 증가하였다. 관목은 봄에서 가을까지 계절 변화에 따라 64-100% 증가하였다. 계절에 따라 정원의 포인트 식물이 달라 졌으나, 꽃이 만발하는 초본과 관목으로 나타났다. 색채 분석 결과, 정원의 주조색은 식물 생육이 왕성한 봄과 여름에는 녹 색에서 짙은 녹색으로 나타났고, 가을에는 갈색으로 확인되었 다. 강조색은 계절에 따라 분명하게 달라졌으며, 주로 계절별 특징적인 화색이나 잎무늬로 결정되었다.

We investigated the effect of habitat environment and colony characteristics on floral bud development in Rhododendron brachycarpum native to Ulleung Island of Korea. Two habitats were considered. Habitat B had a remarkably higher altitude and steeper slope than habitat A. Therefore, fewer types of trees existed on the upper layers, and the density was low. Hence, the degree of light transmission within the community was higher in habitat B. Additionally, flowering ratio of shoots was higher in habitat B, and the amount of light was also relatively higher. The lower the amount of light, lesser the floral development, the higher the leaf area and the specific leaf area, lower the dry weight and chlorophyll content. The total carbohydrate (T-C) and nitrogen (T-N) in shoots are more important than the relative T-C and T-N ratios per leaf. Finally, this study revealed that the floral bud development and flowering of native rhododendrons are strongly associated with the degree of assimilate accumulation in shoots, and that sufficient assimilate accumulation in shoots is essential for stable flowering.

The purpose of this study was to develop synbiotic materials and to apply them to the puffed grain products using electrostatic spraying technology. Lactic acid bacteria were isolated from Kimchi and selected through tests of acid resistance, bile salt resistance and γ-aminobutyric acid (GABA) content. The isolated Lactobacillus brevis CFM21 produced highest GABA production up to a concentration of 926.42 μg/mL when grown in MRS broth containing 0.8% MSG. The possibility of coated grains as a prebiotic material was evaluated Confocal laser scanning micro scopy (CLSM). Rice bran extract containing 2% dextrose, 2% soytone, 0.2% potassium chloride, 0.6% MSG was produced 524.77 μg/mL of GABA. Citrus sinensis oil showed the highest antibacterial activity against Clostridium perfringens Electrostatic spray showed much higher effectiveness than conventional spray in coating the puffed grain product through CLSM. Applying Rice bran culture and Citrus sinensis oil to puffed grain product using electrostatic spray could contribute to promote intestinal health of consumers.
