The objective of this study was to know prospect and present state of new variety breeding of Forage and Grassland in South Korea. The industry of forage in Korea is going up to expend through utilization of good quality forage, Italian ryegrass, forage corn and oat rather than rice straw. Especially, since 2007, Italian ryegrass(IRG) had been very important major winter forage crop in South Korea and developed 13 varieties including very early maturity variety (three varieties), early maturity variety (three varieties), medium maturity variety (one variety) and late maturity variety (six varieties). But the disadvantage of Italian ryegrass was weak winter hardness and drought but has good advantage of forage nutritive value, high-yielding and high sugar content, and like livestock as like hanwoo, dairy cattle, goat so on. The Ko-variety (Korea developed variety) of Italian ryegrass has high cold-tolerant and adaptability more than any other country developed variety, and expend to cultivation area from southern area (below Daejeon) to middle-northern area (upper Han river). Although the cultivation area of Italian ryegrass of South Korea was 21,700 ha in 2007, right now, that of Italian ryegrass is about 123,600ha due to expend cultivation area and know famer to good forage crop and have a various maturity varieties (very early, early, medium, late) according to local situation (before-crop harvesting stage or double cropping system). The seed market of Italian ryegrass in South Korea becoming extended to around 100 million Korean won and seed export get nearer to foreign country. We are going to develop of new variety for stress tolerant and high yield and quality forage variety, good adaptability to the Korean environmental conditions including reclaimed area, make self-sufficiency system for forage seed (Italian ryegrass), export our seed to foreign countries.

Crop production in rice paddy fields is of great importance because of declining rice consumption and the low self-sufficiency ratio for field crops in Korea. A controlled drainage system (CDS) is recognized as an effective means to adjust water table (WT) levels as needed and control soil water content to improve the soil environment for optimum crop growth. The present study evaluated the effects of a CDS on soil characteristics, including soil water distribution and soybean development in paddy fields. The CDS was installed with two drain spacing (3 m and 6 m) at the experimental paddy field at the National Institute of Crop Science, Miryang, Korea. It was managed with two WT levels (0.3 m and 0.6 m) during the growing season. Soil water content, electrical conductivity and plant available nitrogen content in the soil were significantly greater in the 0.3 m WT management plots than in the 0.6 m plot and the control. At the vegetative stage, chlorophyll content was significantly lower with higher WT control because of excess soil moisture, but it recovered after the flowering stage. Soybean yield increased with WT management and the 0.6 m WT treatment produced the greatest grain yield, $3.38ton\;ha^{-1}$, which was 50% greater than that of the control. The CDS directly influenced outflow through the drains, which significantly delayed nutrient loss. The results of this study indicated that WT management by CDS can influence soil characteristics and it is an important practice for high yielding soybean production in paddy fields, which should be considered the crop growth stages for stable crop production.
In order to reduce greenhouse gas by 30% compared to BAU in 2020, research and development of zero-energy building construction technology for reducing greenhouse gas emissions in the construction industry is being conducted. With the recent implementation of the policy as mandatory through the establishment and commercialization of the zero energy building base, the government should devise measures to support and expand technology through the identification of the current status of the zero-energy building incentive system and the erasure of the erasure. In order to implement zero-energy buildings, excessive construction costs are presented as a major issue in revitalizing the supply of new and renewable energy to enhance Passive (energy efficiency grade of 1++) and achieve self sufficiency of energy (20% or higher). In this paper, the major problems and solutions for zero-energy building identification were presented in order to activate the dissemination of zero-energy buildings, and the recent policy changes resulting from the mandatory use of zero-energy buildings were analyzed.
The government mandates gradually zero energy building and Photovoltaic power generation systems installed in buildings are emerging as the most realistic alternative to increase the independence rate of building energy. In this study, we propose a method to reduce the power consumption of households by increasing the PV capacity of balconies and applying the method used the charged electric power stored in batteries after sunset. In order to evaluate the electric power energy savings of the residential BESS, a balcony PV 1.2 kW and a battery pack 2 kWh were installed for 9 houses in 4 apartments in Seoul and Gyeonggi-do. The BESS is charged when the balcony PV is generated electric power, and when solar power generation is finished, it supplies power to the electric appliances connected to the load. As a result of installing the solar PV module 1.2 kW and 2 kWh class BESS for 3 households located in Seoul and Gyeonggi-do, the average electric power consumption saving rate was 40%. The reduction in electricity consumption in the case of zero generation surplus power by maximizing the utilization rate of BESS has been improved to about 53%. Therefore, in order to increase the self-sufficiency rate of electric energy in apartment houses, it is effective to increase the solar photovoltaic capacity of the balcony and apply the residential BESS. In the future, it is believed that the balcony PV and home BESS will play a key role in achieving mandatory zero-energy housing.
Recently, we consist in the crucial juncture have to develope culture goods which is worth standing for our nation's endemism. In this vein, this study tried to reproduce and apply it to the present time by the consideration of various elements such as the kind, the use and the fabrication of sewing craft-works was beloved in women's quarter called Kyubang in the Chosun dynasty. With this, this study was designed to develope craft-works which can make an appeal to foreigners with the merits between contemporary factor and traditional factor. The findings of this study were as follows; First, since economic system in the Chosun dynasty was based on home handicrafts and self-sufficiency, it was a commonplace of the Chosun dynasty that home industry such as sewing, spinning and sericulture was thriving among all the women without social ladder. And also, since women of the day were governed by confucian tradition and moral obligation, they mainly have to live in women's quarter called Kyubang restricted to visitors. For the reasons, Wives of the time have no choice but to spend their time by sewing in the promotion of virtues for woman. In additions, they made an effort to pray for the longevity, the wealthy and the fertility of their family members. Second, the sewing instruments is necessary for women's sewing. And also, since sewing instruments was considerably scientific, efficient in those shape and structure, this instruments could save wives a lot of trouble. Third, since many people were convinced of the functions as practicality as well as fanciness, the sewing craft-works were very useful to them in leading their daily life. Fourth, the reappeared works were a total of 22, and the applied works were a total of 17.
To achieve self-sufficiency in good production, cotton should be grown after barley in the southern part of Korea. But, this cropping system reduces cotton yields and fiber qualities in the current leading cotton varieties because of the short frost-free growth period. Ethrel-treated plots shortened the time to open boll by about 20days, increased the percentage of open bolls before the first frost from 38% to 93% and increased yield by 15-38%. There are not significant differences in staple length, tensile strength of the fiber, single bollweight, 100 seeds weight and germination percentage of the seeds between Ethrel-treated and untreated plots. Ethrel should be recommended to the farmers growing cotton after barley harvest.

Peru is located on Andean Range and faced Pacific Ocean and one of the important oil and gas production countries in the South America. Peru's oil business have been invested by foreign oil companies due to the good investment environment, even though the Peru could not be self-sufficiency in oil. Increase in oil price of the world has contributed to the oil and gas developments and productions in the last few years in many oil and gas blocks, such as in the 1-AB blocks and Camisea gas field within the Amazon jungles. Korean oil companies also have obtained several oil and gas blocks in the Peru in last few year, corresponding with the resources diplomacy of Korean government. Investment is strongly expected to be increased in the Peru's oil business due to positive investment environment, such as low royalty rate, tax avoidance, and the favourable terms of the contract to foreign companies etc.

This study is a design study related to the application of 3D printer technology for garment printing. Knitting, which used to be a home industry in the early days, originally comes from hand-knitting. This evolved with various personal devices as a small job for the self-sufficiency of early European housewives. In addition, since the Industrial Revolution, mechanical production entered the mass production mass supply system, and various apparel products were provided to consumers in accordance with mass standardized dimensions. This is similar to the development process in Korea. In addition, it has formed a considerable market with the situation that it can produce and supply apparel products at low labor costs of first-generation Namdaemun and Dongdaemun merchants. As the production shifted to the Southeast Asian region due to the increase in labor costs in the domestically developed social situation, the production of garment products in Korea is now almost 5%. As a result, apparel-related production facilities and related companies are constantly moving to other countries to move production facilities sensitively due to rising labor costs. Recently, smart factory automation has been planned to explore new possibilities. In addition, in recent years, with the evolved appearance of consumers, the appropriate supply of the right amount of production has appeared, and the 3D printer applied to personal garment output has attracted considerable interest in the customized market. Therefore, in order to become a new hope and a small addition to various clothing workers, this study conducted related research on the following 3D printers for clothing output and attempted to proceed with a new design.
This study compared and analyzed existing studies and released papers to identify the "definition and scope of urban agriculture" which correspond to the circumstances of Korea based on the fact that urban agriculture was selected as one of the measures to pursue green growth by the Presidential Committee on Green Growth (PCGG) and the discussions and deliberations among PCGG, government, academia, civic organizations, and experts. It also aims to present the ways of policy to facilitate the development of urban agriculture based on the mentioned identification. This research proposes the definition of urban agriculture as 'all agricultural activities that incorporates multi-functional public benefits of agriculture performed within the administrative district of a city. However, the scope of urban agriculture should exclude the agricultural sites, the methods, and the activities that are against the multi-functional public benefits of agriculture, which will be determined depending on the spaces, methods, and purposes of planting food crops. In order to facilitate the development of urban agriculture, the government should implement the policy measures as following: (1) to analyze spaces for farming, and provide the spaces to the citizens; (2) to prepare legislation and institution that will allow citizens to use the farming spaces continuously; (3) to develop Korean-style urban agriculture model that fully reflects the features of Korean cities; (4) to develop a system where the urban citizens can easily learn and experience the urban agriculture; and, (5) to provide incentives that will attract active participation of urban citizens such as carbon mileage. (6) to analyze effect of urban agriculture to save energy and food self-sufficiency.
Objectives: This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used. Results: Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin $B_2$ were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level. Conclusions: These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.
