본 연구 시험포장의 토양은 식양질의 지산통으로 우리나라 논토양의 평균적인 화학적 특성과 비교하면 유효규산과 pH가 높았으며 유효인산과 유기물함량은 낮았다. 관행 및 유기재배구의 생육특성은 초장과 수장, 분얼수는 유의적인 차이가 없었으며 입모수의 경우 유의적인 차이를 보였다. 유기재배구에서 관행재배구에 비해 잡초발생이 많았으며 이는 수확작업 시 수확량의 손실에 지대한 영향을 미쳤으며 주요 초종으로는 뚝새풀과 벼룩나물이었다. 밀의 생리장해로서 도복의 발생은 유기재배구보다 관행재배구에서 더 많이 발생하였는데 이는 질소질비료의 시용량과 관련이 있는 것으로 보여진다. 병해충발생은 겉깜부기병, 붉은곰팡이병, 흰가루병, 잎마름병, 누른모자이크병, 노린재류, 진딧물이 발생하였으며 유기재배구에서 겉깜부기병과 붉은곰팡이병 다소 발생하였다. 관행과 유기재배구에서 수확한 밀알의 성분분석 결과, 단백질함량은 전남지방에서 생산되는 밀의 평균값보다 낮았고 회분함량은 높게 나타났으며 2019년과 2020년의 연차 간 밀알성분의 차이는 단백질, 지방의 함량은 증가하고 수분, 탄수화물함량은 감소하였으며 회분은 비슷한 함량을 보였다. 2019년의 밀 수확량은 유기재배구(559 kg/0.1 ha)가 관행재배구(532 kg/0.1 ha)보다 더 높은 수량을 보였지만 2020년에는 배수불량으로 인한 누른모자이크병과 잡초 발생으로 관행재배구는 10%, 유기재배구는 30%의 수확량 감수를 초래했다. 2019년의 밀 재배농가의 순수익은 관행재배구(46만원/0.1 ha)로 유기재배구(44만원/0.1 ha)에 비해 다소 높게 나타났으며 경영비는 유기재배구(16.2만원/0.1 ha)가 관행재배구(9.4만원/0.1 ha)에 비해 다소 높았는데 이는 유기재배에서 비료비와 종자비가 관행재배보다 높았기 때문이었다.

감관총채벌레가 2000년에 처음으로 보고된 이후 남부지방에서 계속 분포가 확산되고 있어서 설문조사를 통해 그 분포확산 정도를 조사하였다. 조사결과 감관총채벌레는 1995년에 전남 장성군에서 최초로 발생하였으며, 현재는 울산광역시와 충북, 전북, 전남, 경북, 경남, 제주 등 6개 도의 26개 시군에서 발생하고 있고, 경남의 창원과 밀양 지역이 피해가 가장 심하였다. 1995년부터 2003년 4월까지 누적된 발생면적은 총 151 ha이었으며, 단감 뿐만 아니라 떫은감에도 발생하였다.

Ketosis can exist in both clinicla and subclinical forms. Detection of the subclinical form of ketosis by the use of a nitroprusside based test powder gas been shown to be a relatively simple and reliable procedure. Howere, very liffle is known about the indcidence or prevalence of the subclinical ketosis in Korea. In the present study, samples of urine taken from 288 dairy cows in Chonnam area were examined to demonstrate the presence of ketone bodies, using ross test. All the cows were within 4 weeks either before or after parturition. The gerd size was from 10 to more than 100 cows, and the cows did not show any clinical signs of ketosis. Of the 288 cows, 85 (29.5%) were positive to Ross test; of the positive cases 42.4% were +, 44.7% were ++, and the remaining 12.9% were +++. The prevalence increased from 3rd parity, peaked at 6th parity and thereafter decreased. The prevalence was higher after parturition than before parturition, with the highest occurrence during the 2nd week after calving. The prevalence was higher during winter. Also cows kept indoor throughout the year showed higher occurrence of the subclinical ketosis. The subclinical ketosis did not affect the specific gravity of the urine; however, increasing amount of ketone bodies in the urine decreased the pH of urine.

A total of 576 fatteners selected randomly from 6 Korean native goat farms in Chonnam area were examined for louse infestation from March 1997 to February 1998. The lice collected from the goats were identified. Four goat farms were selected and 20 goats were randomly chosen from each farm; blood samples were taken from the goats seasonally and examined hematologically and chemically. It was found that 495 out of 576 goats (85.9%) were infested with lice. The infestation rate in one of the 6 farms reached 92.9%. Two species of lice were identified; Linognathus sp. (sucking lice) and Bovicola sp. (biting lice). Goats infested with lice showed higher values in white blood cell, neutrophil and eosinophil counts than the goats not infested counterparts; same trend was seen with total protein, albumin and globulin concentrations. The results of this study indicate that louse infestation in the goat should be investigated extensively in view of the goat farming.

Korean Traditional houses has been evolved and developed in many years, adopting the natural environment to control exterior conditions. These control method are various passive system of using natural materials, considering micro climate, building lay out, and these system are more natural and ecological to make the comfortable indoor climate than active systems of the present houses. This study aims to analyzed control performance of outdoor environment of five Korean traditional houses during the summer and winter. These houses are varied with lay out and floor plan to reflect the way of control for environmental condition, surveyed the reverberation time and sound level difference between rooms of the main living room and other main floored room, master room and kitchen. Especially air temperature and humidity have been measured simultaneously in each rooms to compare with outdoor condition. As a result, the variation of air temperature and humidity of most rooms are considerably static while condition of outdoors are much varied, it is showed that indoor climate has been controled with traditional soiled walls.

Information on certain reproductive traits were obtained from field material. The data for this study were taken from 1,111 breeding records of 273 cows and 193 heifers at Koheung, Chonnam, during the period 1979 to 1984. The cattle were bred by artificial insemination; only one or two cattle were reared by one farmer. The heifers were first bred at 551.75 days after they were born; they were pregnant at 569.06 days after birth. The average estrous cycle length was 21 days; the average number of inseminations per conception was 1.56. The non-return rate for first inseminations for cows and heifers was 62.5% and 59.6%, respectively. The gestation length was 285.79 days. Of 1,111 viable calved born 582 were male, giving a sex ratio of 100:110. The average length between calving and first insemination was 88.9 days; average calving interval was 397.69 days.

Reproductive failures, such as abortions were occured among dogs in a large kennel in Chonnam area April in 1994. After an initial positive result by the 2 mercaptoethal rapid slide agglutination test(2ME-RSAT) to Brucella canis on five sera, additional specimens from all dogs in the population were tested. The blood cultures and 3 following serological tests (2ME-RSAT, TAT, AGID) performed on all samples on the basis of surveys, the following results were obtained. 1. Thirty three of 62 dogs were seropositive. 2. Twenty blood samples from 33 dogs were cultured, all of the isolates were identified as B canis. 3. Although there was not siginificant difference in sex, age and breed of the cause brucellosis dectected, abortions was occured late in gestation stage.

The epidemic of tsutsugamushi disease, along with hemorrhagic fever with renal syndrome(HFRS) and leptospirosis, has been ingrowing concern as it occupies a considerable proportion of the so-called seasonal febrile illnesses in autumn in Korea. This study was conducted to describe certain epidemiologic characteristics of the reported cases of the tsutsugamushi epidemic in Chollanamdo province in 1991. The findings could be summarized as follows: 1. Among three seasonal febrile illnesses in Autumn, tsutsugamushi disease occupied 91.9 percent of whole serologically confirmed cases. 2. Male-female sex ratio was 1 : 1.8. Majority of cases (77.4% in men, 65.1% in female) were in older age group (>=50 year of age). 3. Date of disease onset were distributed between late September and November. The 67.4% of cases were developed from October 21 to November 10, 1991. 4. The 41.5% of cases were reported from southern maritime districts. Reported dates of index cases and median cases were earliest in inland districts followed by southern maritime and latest in western maritime districts. 5. Most frequently reported clinical symptoms were chill (100%), high fever (100%), headache (81.7%), and skin eruption (70.4%).

2010년산 쌀보리 43시료, 겉보리 17시료, 맥주보리 11시료, 청보리 14시료, 밀 41시료 등 총 126개 시료를 농가로부터 채집하였다. 이들 시료를 대상으로 Fusarium균 오염정도와 이들 균이 생산하는 주요 독소인 DON, NIV, ZEA의 자연발생을 조사하였다. 2010년산 맥류의 전국 평균 오염율은 23.0%로 2009년 전국 평균 오염율(Yeh 등, 2010)에 비해 10% 이상 높았다. 지역별 오염율은 전남지방의 맥류가 35.8%로 가장 높았고 전북 20.8%, 경기 20.5% 순이었다. 각 독소별 오염빈도와 오염수준을 조사한 결과, DON은 43시료(34%), 0.89 mg/kg 이었고, NIV는 107시료 (84.9%), 1.86 mg/kg, ZEA은 13시료(10.3%), 0.06 mg/kg이 었다. NIV의 오염빈도가 DON과 ZEA에 비해 높았다. 한편 40시료(31.7%)가 DON과 NIV가 중복오염되어 있었다. 맥류 종류별 곰팡이독소의 오염수준을 보면, 밀에서는 DON의 오염수준이 NIV보다 높았으며, 보리에서는 NIV 오염수준이 DON보다 높았다. 보리 종류별 NIV의 오염수준은 청보리, 맥주보리, 쌀보리, 겉보리 순으로 높았다. 독소오염에 대해 지역별로 분석하여보면 경기, 충남북의 중부지방은 DON의 오염수준이 NIV보다 높았으며, 전남북과 경남북의 남부지방은 NIV의 오염수준이 높았다. DON과 NIV 독소의 오염빈도 또한 중부지방에 비해 남부지방이 많았다. 지역별 맥류 곰팡이독소 자연발생 양상의 차이를 처음으로 보고한다.
