This study aims to identify the causation effect between technostress and utilization of Internet information and meditation effect of information service acceptability between technostress and Internet information utilization. The data were collected from 503 woman farmers aged 20 to 65 across the country. The analysis performed a three-stage mediated regression of Bron, & Kenny (1986), using the SPSS 21.0 statistical package. The importance of accepting information services has been identified in the Sobel test. According to the analysis of the medium effect on information service acceptability, information service acceptability has a partial medium effect on the technological stress of woman farmers and the level of Internet information utilization. In order to lower the technology of woman farmers in the future, it is necessary to find ways to improve new perceptions of information technology and increase acceptability of information services.

We intend to analyze reasons for low acceptability of protective clothing in pesticide-spraying farmers in Korea, and to use the information for designing new clothing with better acceptability. To understand the attitude of farmers toward wearing protective clothing during spray, a survey was performed on 256 farmers. It is evident that the stress, which is caused by inadequate body temperature regulation, and its accompanying physiological responses are two of the leading factors for the low acceptability of protective clothing. Although the cost of clothing is not an important factor currently, low cost clothing is desirable in the future. Fancy of design is unimportant for new clothing. The results are discussed in conjunction with a desirable research focus for new types of protective clothing. Efforts should be made to ameliorate thermal stress through protective material development and garment design.

This survey was performed to gain basic information for the development of new protective clothing of high acceptability in pesticide splaying among small size farmers. The rate of protective clothing wearing was low during pesticide spray although they understand its necessity. The reason for this low acceptability was related to the heat stress and reduced work efficiency deriving from wearing protective clothing. Instead of wearing they tend to carry out spray work while the ambient temperature is not to high. In the similar context, they rather intend to spray in consideration of weather condition instead of wearing protective clothing in the future. However, they are willing to purchase protective clothing if desirable products are developed: the clothing need to be efficient in both protection and work performance; the fanciness in design is not a requisite. This survey result will provide information necessary for the direction of new protective clothing development.

The total area of domestic reclaimed lands is 54,379 ha, and among these, 30,394 ha can be agriculturally available. To increase an agricultural availability of reclaimed land, controlled horticultural products that can be highly profitable have come to the fore. However, as being characteristically concerning, when original glasshouse is intactly applied in reclaimed land, it is unsafe on account of ground subsidence and, even if ground were reinforced, it has a problem by high cost. So a new greenhouse model would be necessary taking into account not only cost-efficiency but also safety with relatively light-weight one. Before this, this paper estimated acceptance rate of controlled horticultural complexes in reclaimed land and new greenhouse model for 414 farmers. The annual rental fee is 129,712,500 won/ha, considering the interest rate (2.5 %) of the investment, the depreciation cost of the facilities (straight line depreciation method, 20 years of service life estimated), and government subsidy rate (50 %) which resulted in a sufficient number of intended tenants with the acceptance rate of 0.33. The results of this paper may contribute to the government's policies for reclaimed land.

고추 자원을 최대 활용하고, 농가의 수익을 올리기 위하여, 청고춧가루로 김치를 제조한 후 홍고춧가루와 김치와 pH, 총산도, 생균수, 젖산균수 및 관능 등을 비교 검토하였다. 청고추 김치와 홍고추 김치의 pH 및 총산도의 변화 양상은 거의 같은 것으로 나타났다. 또한 두 김치의 적숙기 초기에서 말기까지, 생균수와 젖산균수에 있어서도 거의 같은 양상을 보였다. 그리고 관능은 청고추 김치가 홍고추 김치에 비해 전반적으로 아주 낮은 값을 보였는데, 이는 김치의 붉은 색에 대한 기본 관념 때문인 것으로 사료된다.

The objective of this study was to compare pork characteristics and to determine consumer acceptability of pork chops from antibiotic free Yorkshire crossbreds sired by Berkshire (BY), Large Black (LBY), Tamworth (TY) or Yorkshire (YY) boars and reared in hoop houses. The experiments were conducted at the North Carolina Agricultural and Technical State University (NCA&TSU) Farm in Greensboro, NC and the Cherry Research Station Center for Environmental Farming Systems (CEFS) Alternative Swine Unit in Goldsboro, NC (source of antibiotic free Yorkshire sows used at both places). Twenty-four sows were artificially inseminated at each location in each of three trials. Litters were weaned at 4 wks old, and reared within deep-bedded outdoor hoop houses. To compare pork characteristics, 104 randomly selected animals were harvested at a USDA-inspected abattoir at approximately 200 d of age. Variables measured included pH, color score, $L^*$, $a^*$, $b^*$, marbling score, drip loss, hot carcass weight, backfat thickness (BF), loin muscle area (LMA), and slice shear force. Sensory panel tests were also conducted at two time periods. The data was analyzed with GLM in SAS 9.01 including location, trial, and sire breed as fixed effects. Backfat thickness, LMA, color score and $a^*$ were different among breeding groups (p<0.05). The LBY pigs had thicker backfat and smaller LMA than the other breed types. The TY and YY had less backfat than all other breed groups. Color score was lower for YY than BY and LBY but intermediate for TY. The $a^*$ was lower for TY than other breeds except LBY which was intermediate. For one sensory panel test, YY pork was more preferred overall as well as for juiciness and texture compared to BY and LBY (p<0.05), but no impact of breed type was noted for the other test, with values similar for BY, LBY, TY and YY pork. This information may help small farmers make decisions about breed types to use for outdoor production.

본 연구는 국내에 설치되어 있는 액비저장조의 운영실태를 조사하고, 액비저장조에서 발생되는 악취물질을 구명하고자 수행하였다. 1. 국내에 200톤 규모의 액비저장조를 설치한 60 농가를 대상으로 한 본 조사에서 약 $93\%$가 액비저장조를 제대로 가동을 하고 있었으며 이중 $57\%$가 액비제조시 폭기 처리하고 있었다. 2. 조사 농가 중 년간 액비의 활용 횟수는 2회가 $50\%$로 나타났고 액비의 부숙 효과를 높이고 악취를 저감시키기 위한 목적으로 $64\%$가 미생물제제를 첨가하고 있었다. 반면에 액비 이용시 인력 장비의 비용 및 악취물질 발생 저감을 위한 첨가제 비용이 $43\%$로 조사되어 액비이용 시 문제점으로 지적되었다. 3. 액비 제조 형태별 악취물질 발현양상으로 호기 제조시 액비저장조내에서는 iso-valeric acid가 0.012에서 0.07ppm, Propionic acid가 $0.17\~2.85ppm$의 범위로 검지되었으며 혐기 제조시에는 n-Butyric acid가 1.5에서 2.3ppm, n-valeric acid가 $1.3\~1.8ppm$, acetaldehyde가 0.8에서 2.1ppm로 검지되어 호기 제조방법과 혐기 제조방법 모두 휘발성 지방산의 농도는 악취방지법의 규제농도 이상이었다. 부지경계선에서의 악취물질을 보면 호기시에는 미검출로 나타났고 혐기 제조시에는 Acetaldehyde가 $0.4\~0.9ppm$ 수준으로 검지되어 악취방지법의 규제농도를 초과였다.

본 실험은 저항생제 수준에서 스테비아와 숯의 급여가 돼지의 도체 및 육질특성에 미치는 영향을 구명하고자 수행하였다. 시험구는 일반 기본사료를 기초로 하여 T1(대조구, 기본사료 + 비육전후기 항생제), T2(기본사료 + 0.3% 스테비아 + 0.3% 숯 + 비육전후기 항생제) 및 T3(기본사료 + 0.3% 스테비아 + 0.3% 숯 + 비육전기 항생제)로 나누어 실시하였고, 항생제(oxytetracycline, OTC) 수준은 기존 첨가 수준(110 ppm)의 50%인 55 ppm으로 첨가하였다. 저항생제 돈육생산 가능성을 위하여 비육후기 무항생제 처리를 하였다. 숯과 스테비아, 항생제를 각기 다르게 급여한 돼지의 도체특성에서 A등급 출현율은 T3에서 59%로 가장 높게 나타났으며, 등지방 두께는 T2에서 높게 나타났다. 도체장도 T2에서 높은 수준을 나타내었다. 일반성분에서는 모든 처리구에서 유사한 수준을 나타냈다. 육질특성에서 pH는 모든 처리구에서 정상의 범위를 나타내었으며, 보수력은 T3에서 다소 높은 수준이었다. 육즙손실은 T2에서 높은 육즙손실량을 나타내었으며, 가열감량에서도 T2에서 유의적으로 높은 수준을 나타내었다. 전단력은 실험군 간에 차이가 없었다. 육색에서 명도는 T2가 높은 수준이었으며, 근육 내 총콜레스테롤 함량은 T1에서 유의적으로 높은 수준을 나타내었다. 주관적판정에서 T3가 다소 높은 마블링 점수를 나타내었고, 관능검사에서는 T1이 전체기호도에서 다소 높은 점수를 나타내었다. 이상의 결과에서 스테비아와 숯을 먹인 비육후기 무항생제 급여구(T3)가 대조구(T1)와 스테비아와 숯을 먹인 비육전후기 항생제 급여구(T2)와 비교 시 도체 및 육질특성에서 유사한 결과를 나타내는 것으로 보아, 스테비아와 숯이 항생제 대체효과가 있는 것으로 생각되며 저항생제 돈육생산이 가능할 것으로 사료된다.
