Global GM crops continue to grow. They have reached 181 million hectares. A total of 28 countries have approved biotech crops for planting. More than 60 countries have approved biotech crops to be imported as food and feed since 1996, meaning that biotech crops are now commonly accepted in those countries. Although biotech crops provide key solutions for the challenge of global food security in the future due to population growth and climate change, there are still some debates on whether biotech crops should be accepted in many countries including Korea. Therefore, it is very important to make people understand that GM crops will provide benefits to both farmers and consumers. In this review, current global status of GM crop development and commercialization are summarized.

An areal elderly migration model (AEMM) was developed to assess the demand of rural development projects targeted towards elderly people. The AEMM was developed with adaptation of the gravity model to represent spatial interaction regarding amenities. Areal characteristics were classified for estimating the amenities from the perspective of net migration. From 1990 to 2000, data were acquired from USCB, PASDA, PAHEALTH, PADCNR, PFBC, and NCDC in 67 Pennsylvania counties for analysis and application. The results revealed that elderly migration can be explained not only by areal characteristics but also by spatial interaction considering the population, distances, and amenities of surrounding areas.

Korea is facing a serious elderly problem, because the elderly population and households have been increasing radically. To cope with the coming elderly problem, social welfare services and elderly housing need to be carefully prepared. Especially, elderly housing has been recognized to be promising to solve the great portion of the problem. In this point of view, I attempted, in this study, to show the theoretical bases on the residential environment for the elderly households and their residential consciousness. I make a survey of residential consciousness of the elderly on 575 Koreans aged 60 or more, and analyze the difference of residential consciousness of them by regional comparison of the elderly. The result of this study will be expected to be a reference to the housing planning for the elderly household in Korea.

Monitoring techniques for afro-ecological environments were studied, Hydrologic and ecological components in conjunction with water quality were monitored in the Balkan watershed. The hydrologic monitoring program consists of four water level gauging stations along creeks and stream at the watershed having 26.5 km2. Stage - storage relationship of reservoir, rainfall amount of the watershed, and rating curve of the stream gauging stations were established. Soil type, land use, hydrologic soil group, population and economic activities within the watershed were surveyed. Water quality data from the streams were sampled weekly and chemical analysis was conducted. Temporal variations of water quality were investigated and water quality map of each reach of stream was made to identify spatial variations. Seasonal and spatial variations of vegetation densities along stream in the watershed were investigated using grid, Density variations of insect species such as arthropod, flying insect, spider spices, rice insects were also monitored to determine seansonal surveying density. These monitored data will be used to develop monitoring techi%ues and afro - ecological environment models.

In Korean Peninsula including neighboring islands and Japanese Islands identical firefly species or the species belonging to same genera occur together in both territories. These geographic firefly species, nonetheless, have never been subject to taxonomic consideration together until recently, lacking clear species status and phylogenetic relationships. A recent serial study of these fireflies using luciferase gene and/or portions of mitochondrial DNA sequences provided some insight into these populations in terms of validity of species name, phylogenetic relationships, and speciation event. In this article, thus, we have reviewed the recent progress on phylogenetic and/or population genetic aspects of these species, i.e., Hotaria-group fireflies, Luciola lateralis, and Pyrocoelia rufa to better understand the firefly species in these regions.

We intend to improve the sustainability of rural villages by investigating the element technologies and platforms necessary for building smart villages. There are so many investment smart city platforms and solutions in many cities. but there are relatively few investments in rural or small cities. This situation can not only increase the urban problem due to the increase of population to the city, but also deepen the digital gap of citizens. So far, studies on smart village have been investigated in fragments. We will examine the cases applied to smart village as a whole and study the open smart village platform that analyzes the overall data storage and management of the village after the smart village was finally established. First, we will look at the overseas trends of smart village and second, we will study the smart village platform that efficiently manages smart village through the technology necessary for smart village.

The aim of this study was to forecast the future Health Functional Food (HFF) market trends of Korea by studied about policies and market situation in Japan. The HFF is a food that is given an additional health function. In contrast with traditional foods, the HFF has unique characteristics in that it can be produced under the political regulations. The market size of the HFF was growing gradually due to the increased of an aging population and consumer need for high quality and diversified foods. The reason why the HFF market in Japan grew up earlier than other countries, Japan was the first country that institutionalized the HFF policies. Therefore, in this paper, by examining the policies and the market situation of Japan through literatures, we forecasted upcoming political and market situational changes of Korea's HFF market. We noticed that consumers needs about the HFFs which diversified, confidently ensured safety and ingredients will increase. In this regard, the government will reorganize legislation in order to increase the confidence of the safety of HFFs. In addition, the market size of domestic HFFs which are produced by major food companies will grow.

Cultural conditions during production of compost, using wheat straw and chicken litter as raw materials, will affect the microbial and biochemical characteristics, leading to a wide variation in mushroom productivity. Over the past 10 years, chemical and instrumental methods, suitable for assessing compost quality have been studied in Northern Ireland. In addition, the use of near subject of investigation over the past 4 years. Previous studies have shown that NIRS can be used fer assessing quality of dried and milled composts. The aim of the current investigation is to develop NIR calibrations for key quality parameters such as dry matter, pH, nitrogen, carbon, ash, microbial population and fibre factions during the two stages of production using spectra of fresh composts. Near infrared reflectance measurements of fresh composts prepared by 6 producers were made during a two-year period. Although the spectra of fresh composts were dominated by two moisture peaks at 1450 nm and 1940 nm, good calibrations for determining moisture content, conductivity, pH, nitrogen, carbon and fibre fractions were developed. The results of quality assessment during commercial production using the calibrations will be presented and discussed.

The supporting system for agricultural workforce and education strategy has been changing both domestically and worldwide range term. To change the fundamental directions, much more needs to be learned about the process of structural adjustment regarding the dynamics of the agricultural and rural sectors. A rural development doctrine must pay more attention to the ongoing problems of population imbalance and the dissolution of the countryside. The focus should be young people prefer to live in cities because there are more opportunities, services, and great personal fulfillment. This paper was described the effective fostering directions of young agricultural workforce and educational program to prepare future and young farmer for teaching careers in agriculture, food, farm management, and marketing. To achieve these goals, the specific approaches are 1) establish the strong partnership between related organizations of agricultural business, 2) strengthen the management and marketing education of products, 3) create the various in-farming or out-fanning incomes including green tourism, 4) enhance the aggressive marketing strategies by Internet, Telephone, and TV etc, 5) make the association among the same items for the effective research and risk management.
