도시화 진전으로 도시에서 농림어업에 종사하는 노인들이 증가하고 있다. 따라서 단순히 농촌지역 또는 도시지역으로 구분해 노인들의 자살 대응책을 모색하는 것보다는 직업(농림어업 종사)에 따른 노인들의 자살 문제를 고려할 필요가 있다. 이를 위해 본 연구에서는 순위 프로빗 모형을 이용해 농림어업에 종사하고 있는 노인의 자살 의향에 어떤 요인들이 영향을 미치는지를 살펴보았다. 분석결과, 외로움을 느끼는 농림어업 종사 노인의 자살 의향은 3.0% 증가, 일에 대한 가치를 소중히 느끼는 경우 자살 의향은 1.1% 감소, 지역의 소속감을 강하게 느끼는 경우 자살 의향은 2.7% 감소한다. 그리고 매일 만나는 가족이나 친척이 많을수록 농림어업 종사 노인의 자살 의향은 2.5% 감소한다. 하지만 동거 가족수가 매년 감소하고 있기 때문에, 이러한 가족(또는 친척)의 대면 접촉 확대는 한계가 있을 수밖에 없다. 따라서 농림어업 종사자의 외로움이나 가족(친척) 대면 접촉의 한계를 공공기관의 사회적 가치 증진 활동 노력과 연계하는 정책 수립이 필요하다.

본 연구는 목재산업의 e-비즈니스 활용실태를 파악하여 목재산업의 e-비즈니스 발전방안을 제시하기 위하여 수행되었다. 한국에 있어 목재산업의 e-비즈니스 활용실태는 고객과의 전자적 연계, 공급업체와의 전자적 연계 등 e-비즈니스 사업 환경은 낮은 실정이다. e-비즈니스의 활용 수준은 사내정보 인프라 구축단계로 아직은 도입단계에 걸쳐 있는 것으로 파악되었다. e-비즈니스 활용시 장애요인은 숙련된 인재 부족, e-비즈니스 사업모델의 불충분, e-비즈니스 운영기술/수단의 부족 등으로 나타났다. 따라서 목재산업에 있어 지속적인 e-비즈니스 활용수준을 발전시키기 위하여 다음과 같은 점을 고려하여야 할 것이다. 1. 목재산업의 e-비즈니스 활용을 증진하기 위하여 가격경쟁력, 품질경쟁력과 시장대응능력이 유지되는 사업모델이 모색되어야 할 것이다. 2. 목재산업의 e-비즈니스 모델을 수립하기 위하여, 제품 표준화 체계, DB구축, 전자 카타로그 제작등 협력업체간 정보 네트워크의 연계가 중요하고, 기업간 아웃소싱 및 타산업과의 제휴를 확대하여 목재산업 경쟁력을 강화시키는 프로그램 개발이 필요하다. 본고에서는 정량적인 자료의 활용에 있어서 다소 부족한 점이 있지만 광의의 목재산업을 주기적으로 조사하여 e-비즈니스 활용 추이를 전망 예측할 수 있는 출발점이 될 수 있다. 향후 연구에 있어 원목생산자, 유통, 합판 보드류, 인테리어재, 악기 가구 등 업종별 e-비즈니스 활용수준을 계량화하고, 업종간 전자적 연계가 가능한 e-비즈니스 활용 모델의 구축과 평가방법 개발이 필요하다. 또한, 국내외 시장 특성과 타 산업과의 연계성을 갖는 글로벌 e-비즈니스 활용 모델을 발굴하고, 소비자 의사를 반영한 e-비즈니스 마케팅기법의 모색이 요구된다.

Imaging technique or computer vision (CV) technology has received huge attention as a rapid and non-destructive technique throughout the world for measuring quality attributes of agricultural products including meat and meat products. This study was conducted to test the ability of CV technology to predict the quality attributes of beef. Images were captured from longissimus dorsi muscle in beef at 24 h post-mortem. Traits evaluated were color value (L*, a*, b*), pH, drip loss, cooking loss, dry matter, moisture, crude protein, fat, ash, thiobarbituric acid reactive substance (TBARS), peroxide value (POV), free fatty acid (FFA), total coliform count (TCC), total viable count (TVC) and total yeast-mould count (TYMC). Images were analyzed using the Matlab software (R2015a). Different reference values were determined by physicochemical, proximate, biochemical and microbiological test. All determination were done in triplicate and the mean value was reported. Data analysis was carried out using the programme Statgraphics Centurion XVI. Calibration and validation model were fitted using the software Unscrambler X version 9.7. A higher correlation found in a* (r=0.65) and moisture (r=0.56) with 'a*' value obtained from image analysis and the highest calibration and prediction accuracy was found in lightness (r²_c=0.73, r²_p=0.69) in beef. Results of this work show that CV technology may be a useful tool for predicting meat quality traits in the laboratory and meat processing industries.

The purification of sewage deriving from agricultural and food industries is today a serious problem mainly in areas characterized by intensive production plants. The solution examined in this work, involves a system of natural evaporation which employs special panels with a large evaporating surface constituted by an internal cellular structure in polyethilene. Using renewable energy they allow to speed up the natural evaporating effect thus eliminating some drawbacks such as swamps and obtaining sewage concentration with relatively low costs. The institute of agricultural engineering has carried out tests on the disposal of sewage deriving from two very important production sectors; pig-breeding and olive oil production . at a were gathered in order to verify the operating capacity of plants and their variables . On the remaining concentrated part tests were also carried out in order to know its chemical and chemical-physical features and to study the possibility for its us .

Agriculture is more influenced by environmental factors rather than other industries. Among the environmental factors, the meteorological conditions mainly impact the output of agricultural products. Hence, the purpose of this study is to analyze the impact of meteorological factors on the output of elemental agricultural products. As a first step, we obtained the data of the meteorological factors (i.e., precipitation, humidity, temperature, insolation, snowdrifts, wind velocity) and the output of the various agricultural products (i.e., grain, fruits and vegetables, root crops, green vegetables, seasoned vegetables, fruits, special crops) from the year 1990 to 2009 (20 years) of Seoul and the six metropolitan cities in Korea. Then, the analysis of the correlation between the agricultural product with the largest output and the meteorological factors of the place where the corresponding agricultural product is most produced, was carried out in order to determine the core meteorological factor that most impacts the output of agricultural product. The correlation analysis revealed that humidity, insolation and wind velocity have been the crucial meteorological factors to influence the output of the agricultural products. From the result, we can induce that the meteorological forecast information about the vital meteorological factors, i.e., humidity, insolation and wind velocity, facilitates the optimized cultivation plan to maximize the output of agricultural products.

After the Uruguay Round, Korean agriculture industry has been protected and reared with government grants. However, until now there has been very minimal development to establish a solid export industry which can make the most of the trade agreements in place. There has been much research on ways to expand agricultural exports in order to respond properly to this ever changing environment and sustainable agricultural industry. As all other export industries, an efficient logistics network is paramount in order to allow the agricultural industry to respond to changes in demand and penetrate global markets. The lack of systematic logistics activities such as packaging, transportation, unloading, storage, and information transfer in farms has been a major factor in the inefficiency of the agricultural industry resulting in minimal development. From this perspective, 3PL was proposed and applied as a way to build on the streamlining of export of agricultural logistics system. The Agri 3PL is considered as an efficient agricultural exports method as a new concept connecting producers with exporters.

Garlic industries in Korea faced with a increasing difficulty because of the pressure of garlic importation from China is ever increasing than before. Therefore this study was conducted to produce low-cost garlics by mechanized cultivation and the results are as follows. A. By applying machinery(stem cutter and size separator, seeder, harvester) the labor was saved over 70% compare with the conventional cultivation B. Growth characteristics and yield showed no difference in mechanized and conventional cultivation of northern-type garlic. C. When scales were sown by seeder, the sowing-depth varied between 3 to 6cm and the rate of 2-plants emergence in one hole was 14.5%.

Climate changes from global warming and reduction in agricultural land result in volatility of prices of agricultural products, causing a imbalance of food market in Korea. It is necessary to develop a transnational food industry cooperation system among Korea, China and Russia that directly or indirectly affect food industry in terms of the whole industrial network. This study analyzes the value chain and linkage in the agriculture, forestry and fisheries industries in three nations. The unit structure and the industrial patterns of three nations were derived using the World Input-output Table (WIOT) from 2004 to 2014 every five years. This paper is expected to contribute to develop food security cooperation in the northern part of the Korean peninsula and to promote the mutual growth of food industry through industry linkage and cooperation.

The alkaloids, piperlongumine, piperine, pipernonaline, and piperoctadecalidine, isolated from Piper longum L., were found to inhibit the biosynthesis of aflatoxin $B_1$ (AF$B_1$) in Aspergillus flavus WRRC 3-90-42-12. Piperlongumine was the most active among the compounds tested, with a 96% inhibition of AF$B_1$biosynthesis at 0.2% (w/v) supplement in a potato dextrose agar (PDA) medium. The three other piperidine alkaloids, pipeline, pipernonaline, and piperoctadecalidine, also inhibited the biosynthesis of AF$B_1$. Of these three alkaloids, piperoctadecalidine exhibited a potent inhibitory activity with a 100% inhibition of AF$B_1$ production at 0.7% (w/v) supplement in a PDA medium. Therefore, piperlongumine and piperoctadecalidine could be used as antiaflatoxigenic agents in agricultural industries. To determine the antiaflatoxigenic mode of action of piperlongumine, further studies are needed.
