This study is purposed to guide a right planning direction of public spaces in rural village. To do so, this study gives you the causes of transformation and the characteristics of the transformed public spaces in rural village. It classifies three different trends of transformed public spaces; increase, stagnation and decrease. In addition, they are related with rural population, farming types and the social consciousness. There are several characteristics of public spaces comparing before and after the transformation. Public spaces were used as small spaces, housing and farm lands before they were transformed. However, after the transformation, we could see that external spaces are augmented, public spaces are congregated and public facilities are increased.

In this study, considering the difficulties for all farms to convert farm styles to animal welfare-based housing, an experiment was performed to observe the changes in the behavior and welfare of sows when the slat floor was changed to a collective breeding ground. Twenty-eight sows used in this study were between the second and fifth parities to minimize the influence of parity. Using a flats floor cover, the flattening rates were treated as 0%, 20%, 30%, 40%, and 50%. Data collection was the behavior of sows visually observed using a camera (e.g., standing, lying, fighting and excessive biting behaviors, and abnormal behaviors) and the animal welfare level measured through field visits. Lying behavior was found to be higher (p < 0.01) as the flattening rate increased, and sows lying on the slatted cover also increased as the flattening rate increased (p < 0.01). Fighting behavior wasincreased when the flattening rate was increased to 20%, and chewing behavior was increased (p < 0.05) as the flattening rate increased. The animal welfare level of sows, 'good feeding', it was found that all treatment groups for body condition score and water were good at 100 (p < 0.05). 'Good housing' was the maximum value (100) in each treatment group. As the percentage of floor increased, the minimum good housing was increased from 78 in 0% flattening rate to 96 in 50% flattening rate. The maximum (100) 'good health' was achieved in the 0% and 20% flattening rates, and it was 98, 98, and 99 in the 30%, 50%, and 40% flattening rate, respectively. 'Appropriate behavior' score was significantly lower than that of other paremeters, but when the flattening ratio was 0% and 20%, the maximum and minimum values were 10. At 40% and 50%, the maximum values were 39 and 49, respectively, and the minimum values were analyzed as 19 for both 40% and 50%. These results will be used as basic data about sow welfare for farmers to successfully transition to group housing and flat floors.

Objective: The ecosystem of an animal farm is composed of various elements, such as animals, farmers, plants, feed, soil, and microorganisms. A domesticated animal's health is largely connected with the reservoir of bacteria and viruses in animal farms. Although a few studies have focused on exploring the gut microbiome of animals, communities of microbiota and viruses in feedlots have not been thoroughly investigated. Methods: Here, we collected feces and dust samples (4 groups: cattle feces, C_F; horse feces, H_F; cattle dust, C_D; and horse dust, H_D) from cattle and horse farms sharing the same housing and investigated their microbiome/virome communities by Illumina sequencing. Results: Dust groups (C_D and H_D) showed higher microbial diversity than feces groups (C_F and H_F) regardless of animal species. From the microbial community analysis, all the samples from the four groups have major phyla such as Proteobacteria (min 37.1% to max 42.8%), Firmicutes (19.1% to 24.9%), Bacteroidetes (10.6% to 22.1%), and Actinobacteria (6.1% to 20.5%). The abundance of Streptococcus, which commonly recognized as equine pathogens, was significantly higher in the horse group (H_D and H_F). Over 99% among the classified virome reads were classified as Caudovirales, a group of tailed bacteriophages, in all four groups. Foot-and-mouth disease virus and equine adenovirus, which cause deadly diseases in cattle and horse, respectively, were not detected. Conclusion: Our results will provide baseline information to understand different gut and environmental microbial ecology between two livestock species.

In the traditional subsistence farming era in Korea, most of small farmer's housing plots in the rural villages had their boundary barriers of which materials being the natural ones provided from nearby places. However, during the rapid industrialization period from 1960s, a traditional type of boundary barriers in the rural villages had been replaced mostly by low-cost factory-made ones, which means absolute loss of their amenity values as a linear part of villagescape. In spite of many study efforts on boundary barriers of traditional rural houses, detailed historical dating on them after 1960s have not tried up to now, which provoked to try this study. Through the direct and in-depth interviews to rural villagers sampled from 21 case villages, it was found that original boundary barriers structure in most of farm houses was made of natural materials like stone, soil, trees and bamboo, but, replaced by cement block structures mostly during Saemaeul Project period. However, although being relatively minority, traditional ones have been preserved up to now mainly in remote mountainous and seashore villages, but was in very low condition. In the overall view, for more than half a century, boundary barriers of farm houses had been left without public or private improvement efforts. In order to enhance their amenity values, more research works should be carried out on positive reassessment of the traditional ones harmonized with multifunctionalities for modern village life.

Engineering phase of dairy housing systems has close connection with the milk produc- tivity of dairy cattle, the quality of milk, extension of dairy production systems, labor- saving in management of dairy cattle and the like. Moreover, the rate of investment of dairy housing facilities is of relatively high level, However, there has been almost no research effort for the improvement of engineering aspects of dairy housing systems in Korea. The purpose of this study is to find out general engineering problems and to recomm- end the improvement in dairy housing systems in Korea. Field survey by means of questionaire, direct measurements, taking pictures and sketching was conducted to get necessary information for the study. Kyung-ki Do region was firstly chosen for sampling area since it has included more than half of the number of dairy farms of the whole country. The results obtained are summarized as follows: 1. In overall dairy farm layout, the dwellings of workers were ignored in the light of sanitary environment 2. The layout of stalls in a dairy barn belongs mostly to the type of double-row face-out, which is compatible with the emphasis of manure disposal activities. 3. While the width and length of stalls were sufficiently close to the standard dimension, the width of mangers was much less than the standard dimension. 4. The width and depth of manure gutters and the width of working alleys were much. less than the standard dimension. 5. The mooring equipment was mostly in the classes of chain or rope. The watering equipment was not facilitated independantly except the one cese of using watercup. 6. The bucket milkers with one or two bucket milkers with the capacity of two cattles. each were used as milking equipment in most dairy farms. 7. There were only few milk rooms independently spaced from other space, in which the arrangement of milking equipment was much less than the standard condition. 8. The lounging ground area was averaged to be sufficient for the activity of dairy herd. 9. Silos for silage used during winter consisted of mostly bunker silos, trench silos and underground vertical silos. Ordinary vertical silos were considered for the farmers to be inconvenient for the labor saving. 10. From the view point of heat conservation and moisture removal within the dairy barns, windows were not flexible for the easy ventilation and ceiling part was not adequate for temperatur maintenance. 11. Waste treatment and disposal systems were not provided with most dairy farms, therefore the livestock waste pollution problems would be serious in the near future.

A survey was carried out to investigate the symptoms and occurance of reproductive disorder in Hanwoo(Korean native cattle). Data of the reproductive disorder of 561 heads from 28 farm households have been collected from Dec. '95 to Nov. '96 and analyzed calving no, nutritional body condition and housing forms. The results obtained are summarized as follows: 1. The incidence of reproductive disorder was 20.1% and the major common symptoms were repeat breeding(39.8%), anestrous(31.0%), nymphomania(10.6%) and subestrous(8.9%). 2. The incidence of reproductive disorder according to the calving no., that of heifer, calved one to two calving no. and over three calving no. were 20.6%, 13.9% and 34.5%, respectively. 3. Reproductive disorder incidence according to the nutritional body condition was 18.3%, 14.6% and 48.7% at body condition score(BCS) less than 2.0, 2.5 to 3.0 and over than 3.5, respectively. At BCS over 3.0, the symptoms of common reproductive disorder were repeat breeding(17.6%), anestrous(12.2%), nymphomania(10.8%) and subestrous(2.7%). 4. The incidence of reproductive disorder according to the housing form 15.8% and 34.6% for group feeding in open house and individual stanchion feeding in stall, respectively. In group feeding, reproductive disorder incidence of cows raised in space of more than 9.9$m^2$ per head was 14.1%, while that of cows raised less than 9.9$m^2$ per head was 18.2%. And incidence of repeat breeding, aneestrous and subestrous was more frequent in individual stanchion feeding than group feeding.

This study focuses on the regional characteristics observed in the composition and floor plan of folk houses in the Young-cheon region situated in the Southern East inland of Gyungsangbukdo. According to the typical characteristics of the Korean folk house, Young-cheon region is supposed to be classified as the Young-Nam region. Our study shows that the open inverse 'ㄱ' type composition is the most common among others, which consists the living room, UtChae and one BoosokChae that serves as a living room and a farm shop. The typical floor plan is called 'Young Nam type' 'H$\hat{o}$tjib' composed of four rooms. Young Nam type of house has a wall in front of the room floor with a door to make the space with the room floor as the internal space. This can be explained by the climatic conditions in the Southern region of Gyungsangbukdo, which has a very cold winter and has a harsh spring wind in Young-cheon. The structural feature to which we should pay attention is the Young Nam type house has a gambrel roof. The evolutions of the house in the 70s are observed in the roof during the Saemaeul Movement from a hut to a modernized roof. In the 80s, the replacement of the heating system, expansion of rooms, modernization of kitchen, replacement of paper windows, modernization of roof, and construction of amenities had taken place to change the space, construction and structure following the modern house features.

본 연구는 국내 산란계 동물복지 인증농가의 사육형태(무창, 개방, 방사)와 품종별(Hy-Line, Lohmann) 생산성과 질병발생에 대한 기초자료를 수집하기 위해 수행하였다. 초산일령은 무창 151일, 개방과 방사형 계사에서 각각 141일령이었으며, 각 계사의 산란피크는 91.8%, 92.9% 및 86.3%이었다. 사육형태에 따른 18~37주령 산란율은 무창, 개방, 방사에서 각각 70.9%, 77.4% 및 65.6%였으며, 32~36주령 산란율은 91.9%, 90.1% 및 76.2%였다. 평균 오 파란율은 무창, 개방, 방사형 계사에서 각각 2.84%, 1.15% 및 0.23%로 나타났다. 개방계사의 폐사율이 다른 사육형태에 비해 낮았다. Hy-Line의 초산일령은 155일, Lohmanndms 157일이었으며, 산란피크는 각각 92.9%(252일)와 97.2%(237일)이었다. 품종에 따른 평균 산란율은 Hy-Line 83.7%, Lohmann 76.9%였다. Hy-Line의 폐사율은 Lohmann종에 비해 낮게 나타났다. 난중, Haugh unit 및 난황색은 방사형 계사에서 유의적인 차이를 보였다(P<0.05). ND의 항체역가는 개방계사에서 낮았으며, IB와 APV의 항체역가는 3농가 모두 높게 나타났다. SG, SE, SP, FAdV 및 ILT는 사육형태에 따른 세 농가에서 검출되지 않았다. 국내 산란계 동물복지 인증농가는 증가하는 반면 산란계 동물복지 인증농가의 사육형태에 따른 자료들은 매우 부족하다. 따라서 본 연구는 산란계 동물복지 인증농가의 사육형태별 생산성 및 질병발생에 대해 분석한 자료이며, 향후 국내 동물복지 인증을 받은 산란계 농장의 생산성 향상 및 질병예방을 위한 기초자료로서 활용할 수 있을 것으로 판단된다.

Two field studies were conducted to determine the efficacy of difructose anhydride III (DFA III) as a supplement in colostrum replacer (CR) for improving the general health status (judged on the basis of incidence of enteritis, bronchitis, and pneumonia) of group-housed suckling Japanese Black calves. In a preliminary study, CR supplemented with DFA III (6 g) was orally administered within 24 h of calving to eight individually reared calves fed colostrum (DFA III group) (Exp. 1). Subsequently, CR supplemented with DFA III (6 g) was orally administered twice within 2 and 12 h of calving to four calves (DFA III group) that were not fed colostrum (Exp. 2). In both experiments, the health status of the calves was assessed during the preweaning period. In Exp. 2, hematological and blood-chemistry parameters were analyzed 24 h after the second administration of CR and at 1 wk and 1 month after calving. The results were compared between the DFA III and control groups (without DFA III supplementation; Exp. 1: n = 10, Exp. 2: n = 4). In Exp. 1, the number of calves requiring medications for the treatment of enteritis, bronchitis, and pneumonia during the preweaning period was significantly (p<0.05) lower in the DFA III group than in the control group. In Exp. 2, supplementation of DFA III did not influence the gain in body weight of calves during the pre-weaning period. Calves in the DFA III group tended to require medications for a shorter duration than those in the control group (DFA III: 10.3 d/calf, control: 21.3 d/calf; p = 0.07). Significant differences (p<0.05) in the level of mean corpuscular hemoglobin, total protein, total cholesterol, and immunoglobulin (Ig)G were observed between the DFA III and control groups. These differences probably reflect the health and nutritional status of the calves. Additionally, the serum iron and lactoferrin concentrations at 24 h and 1 wk after calving, respectively, differed significantly between the 2 groups. These concentrations might reflect the incidence of infections after calving. The present study revealed that the administration of DFA III as a CR supplement may prevent diseases in group-housed calves during the pre-weaning period.

한국 농업·농촌의 고령화 현상과 농업인구의 감소가 점차 심화됨에 따라 귀농·귀촌을 통한 인구 유입이 절실한 상황이다. 이를 위해서는 귀농·귀촌 희망자가 의사결정 시에 도움을 받을 수 있는 정보 부족 등이 해결해야 할 가장 중요한 문제점으로 조사되었다. 따라서 본 연구를 통해 귀농·귀촌 이주지역 선택 시 요구되는 정보(결정요인)를 알아보기 위해 관련 전문가를 대상으로 AHP 분석을 위한 설문조사를 하였다. AHP 분석 결과 1차 계층의 3개 항목 중에는 "경제적 요인"의 중요도가 가장 높게 나타났으며, 2차 계층에서는 "주택 및 토지가격", "대도시 접근성 및 교통", "주거정보" 등이 중요도가 높은 것으로 나타났다. 이러한 연구 결과가 향후 귀농·귀촌 희망자들의 의사결정을 체계적으로 지원하기 위한 정보시스템에 반영되어 직.간접적으로 도움이 되고, 궁극적으로는 고령화가 진행되고 있는 한국 농업·농촌이 활성화되고 발전하는데 있어 기여할 수 있게 되기를 희망한다.
