Objectives of this study were to compare the environmental effects of digestates produced in bioenergy village on the rice paddy field for recycling. Digestates were applied to the soils and the soil properties and the crop responses were analyzed according to the standard methods of soil evaluation. Plant height and the number of tiller showed similar results in both the conventional and digestate treated field, and the yield of rough rice was higher in the field treated with digestates than that with chemical fertilizer. The amounts of nitrogen absorbed in straw and grain were larger in the digestates-treated field than chemical fertilizer-treated one,and efficiency of nitrogen applied was shown to be the highest in 100% treated digestate of the pig manure. Exchangeable cation and pH increased in the soil treated with digestate after harvesting, but salt was not accumulated. With these results, it was concluded that resource recycling in green town can be facilitated through the securement of arable lands for the application of digestates and the proper use of these fertilizers. Long-term effects of digestate application on the soil environment should be sustainingly studied. 바이오가스를 위주로 에너지자립을 추구하는 저탄소녹색마을 내에서 발생하는 혐기소화액을 순환 이용함에 있어서 벼 재배시 통합혐기소화액과 돈분혐기소화액 시용의 영향을 비교하였다. 토양검정분석을 통해 혐기소화액을 시용하고 토양 특성과 벼의 생육을 조사하였다. 벼의 생육은 화학비료구와 혐기소화액 처리구가 유사한 경향을 보였으며 수확량에서는 화학비료구에 비해 혐기소화액 처리구에서 모두 수량이 높게 나타났으며, 통합혐기소화액은 200%, 돈분혐기소화액은 100% 처리구에서 높은 수량을 보였다. 알곡과 볏짚의 질소흡수량은 화학비료구에 비해 혐기소화액 처리구에서 많았으며 흡수된 질소 효율은 화학비료 처리구에서 가장 높았으며 시용된 질소량의 이용 효율면에서는 돈분혐기소화액 100% 처리구가 가장 높았다. 수확후 토양에서는 혐기소화액을 처리한 구에서 pH와 치환성 양이온이 증가하였으며 염류 집적은 나타나지 않았다. 혐기소화액을 활용할 수 있는 적정 농경지 확보와 토양검정을 통한 적정 양분 시용으로 저탄소녹색마을에서의 자원 순환을 추구할 수 있을 것으로 판단되며, 장기적인 관점에서 농경지 환경과 논 생태계에 미치는 영향에 대한 연구가 지속되어야 할 것이다.

To investigate the technology trends in organic farming using journal article analysis, total 2,378 published articles in organic farming between 1974 and 2014 were analyzed. The number of the articles published in organic farming has been steadily increased since 2006. As for category, articles in the field of producing the safe organic products and management (A) were published relatively dominantly, especially division of nutrient and soil management (AA). In the foreign countries, lots of articles in environmental assessment and safety field (B) were published than Korea. the main institutes published the articles in organic farming were Swedish University, Sweden and US department of Agriculture, USA. In case of Korea, the articles in the field of environmental assessment and safety (B) were relatively merely published, especially division of environment in organic farming (BA). With this study, more research based on the environment and safety fields in organic farming should be focused on.

라오스 쌀 산업 현황 및 생산성 향상 방안

홍승길,펙마니셍 쌍사야사니,황성수,김윤경,차재범,신창호 한국국제농업개발학회 2022 韓國國際農業開發學會誌 Vol.34 No.1

Laos People’s Democratic Republic (Laos) is a country selected by Korea’s priority foreign policy – New Southern Policy. It is also one of Korea’s 24 priority partner countries. The objective of this study was to understand the current status of rice industry and recommendations for improving rice productivity in Laos based on “Agriculture Development Strategy to 2025 and Vision to the Year 2030” published by the Lao government. In Laos, major crops are rice, vegetables, maize, coffee, cassava, sugar cane, and others. Laos achieved rice self-sufficiency in 1999. Its rice production reached up to 3,580,000 tons in 2018. It aims to harvest a total of 5 million tons of paddy rice with a target yield of approx. 1.5 million tons in 2025. Rice consumption per capita totals 160 kg/year in Laos, the highest in the world. The national nutrient program sets its targets as follows: of 2,600 kcal, a recommended daily calorie intake for adults, it aims to lower rice and starch, while increasing calories from meat, vegetables, fat, and so on. This shows that the rice policy is formulated with consideration of improving health of people in Laos as well as boosting rice exports. Based on the agricultural policy and strategy of Laos, it is viewed that the rice industry in Laos can advance further and produce results only when rice industry is linked to the following areas: economic development, farm size expansion, higher productivity through novel varieties and cultivation technologies, scaling-up of agricultural mechanization, greater efficiency in processing, and infrastructure expansions such as roads and reservoirs. If an ODA (Official Development Assistance) project takes a tailored approach considering its actor-specific characters and tasks, it is believed that the project can contribute to the goal of securing sustainability for the rice industry.

홍승길,Hong, Seung-Kil 대한생리학회 1973 대한생리학회지 Vol.7 No.2

It has been reported that vasopressin disperse the melanophore granule of frog skin. The author used hypophysectomized and adrenergic receptor blockaded animals in order to define the mechanism of vasopressin on the melanopore pigment of frog skin. The Rana niglomaculata which could be found in the Seoul area were used on this experiment. The amount of the following drugs were injected into the lymphatic sac of the frog; vaospressin $(0.05\;{\mu}g/g\;B.W.)$, dibenzylin $(0.05\;{\mu}g/g\;B.W.)$, and propranolol $(0.01\;{\mu}g/g\;B.W.)$. The following results were observed; 1. Vasopressin dispersed the melanin granules of melanocyte of frog skin. 2. The melanin granule dispersion activity of vasopressin was observed on the hypophysectomized frog. 3. The melanin granule dispersion was observed on the adrenergic receptor blockaded frog with dibenzylin or propranolol respectively, especially the later one was found to be more obvious. 4. The melanin granule dispersion was observed on the frog which was injected with vasopressin after alpha-receptor or beta-receptor blockade and the later one was found to be more obvious. 5. The melanin granule dispersion was more effective with the blockade of beta-receptor after the treatment with vasopressin on hypophysectomized frog.

망 효율성을 고려한 P2P 스트리밍 시스템 설계 및 구현

Recently, many researches on P2P overlay network-based multimedia streaming services have been actively performed because of their high scalability and cost-efficiency advantages. However, P2P overlay networks also have the shortcoming of generating higher traffic owing to their unicast-based one-to-many multimedia deliveries. In order to reduce the traffic generated by the P2P streaming overlay network, we propose an ISP and locality-based parent node discovery method and check its feasibility through an implementation of a prototype streaming system. The measurement of RTTs and hop counts for random nodes having different ISPs and localities shows the proposed method to be able to shorten about 32% RTTs and about 17% Hop counts.

토의 - 해결방법 요지

현재 우리나라 보건소사업을 Part별로 토의된 것을 대략 요약해보면, 정부에서 근래에 시도하고 있는 진료대상이 한정된 영세민이나 생보호자에게만 국한되어 있으며, 치료보다는 예방에 힘써야 하겠다는 점을 들 수 있겠고, 모자보건의 무료분만을 대폭 완화하여 최소한 보건소에 등록되어 있는 임산부만이라도 모두 혜택을 주는 방향과 적기에 예방접종을 실시하도록 하며, 결핵은 조기발견, 조기치료, 예방접종이 중요하다는 것을 결핵사업에 종사하는 모든 요원들이 주민들에게 인식시킬 것이며, 가족계획에 있어서는 모자보건향상에 목적을 두고 사업이 이루어져야 한다는 점을 아울러 강조한다. 끝으로 선진국은 인구 2,000명에 보건간호원 1인 꼴인데 우리나라는 12,000:1이므로 선진국에 비해 6:1이나 되는 보건간호원의 업무과다로 질적인 사업의 기대가 어려우므로, 인력과 경제소모를 억제할수 있도록 기구개편이 필요하며, 간호원이 가정방문시 기능별로 $4\~5$인의 중복방문으로 인한 인력낭비와 사업 우선 순위가 혼돈되어 전반 간호사업이 시급하다는 점을 들 수가 있다.
