Traditional business intelligence (BI) systems have been used widely as tools for better decision-making on time. On the other hand, building a data warehouse (DW) for the efficient analysis of rapidly growing data is time-consuming and complex. In particular, the ETL (Extract, Transform, and Load) process required to build a data warehouse has become much more complex as the BI platform moves to a cloud environment. Various BI solutions based on the NoSQL database, such as MongoDB, have been proposed to overcome these ETL issues. Decision-makers want easy access to data without the help of IT departments or BI experts. Recently, self-service BI (SSBI) has emerged as a way to solve these BI issues. This paper proposes a self-service BI system with farming data using the MongoDB cloud as DW to support the selection of new crops by return-farmers. The proposed system includes functions to provide insights to decision-makers, including data visualization using MongoDB charts, reporting for advanced data search, and monitoring for real-time data analysis. Decision makers can access data directly in various ways and can analyze data in a self-service method using the functions of the proposed system.

Recently, the trend is an increase in prep and existing entrepreneurs returning to farming, people who take over the business and work on a secondary inauguration, and those who are in the field of processed food or exposing farm arisen from the activation of the sixth industry. However, the fact is that majority of an agricultural education is about production process technology education of farm product and processed food under a government-affiliated organization, so the education for start-up, management, or marketing are scarcely proceeding. Rapidly changing customers' demands and trends, agricultural product and food market opening cause a crisis in the field of agrifood. To turn this crisis into opportunity, return farmers need to be fully qualified as an entrepreneur and enterpriser, so that they improve their business mind-set such as plaining, manufacturing and marketing items in a customer perspective, and have ability to take action against imported goods. Also there is a necessary education to change recognition and enhance their ability as an entrepreneur. This study gives a proposal that an agricultural education should expand and strengthen for practician in the field of agrifood to inspire mind-set, change recognition, and enhance their ability as an entrepreneur, and aim at basically figuring out reality of current agricultural education which has not been systematically studied yet, and also establishing theories associated with that. This study is composed of present state, content, drawback, improvement plan of the current agricultural education intended for five of education managers and instructors who provided various education about inception towards farmers, returning farmers, and prep entrepreneurs who have already started up or get ready to do the business in agrifood field.

This study aims at the augmentation of reliability of the long-term rainfall runoff model. To do so agricultural water uses are evaluated by analyzing the effects of small scale irrigational hydraulic structures on long term runoff processes and thereby rainfall-runoff model is modified considering them. As a result the simulation results of the sub-basins having more agricultural reservoirs than the others are disagreed with the observations. The 2nd quarter simulation results show similar trend to it. Especially the farming seasonal results of the drought year as the year of 2008 have many negative discharge values due to the lack of agricultural water uses. This result come from the water uses input data corresponding to not real water uses but water demands. In this study the formulas are derived to estimate the discharges and return ratios and the long term rainfall-runoff model is reformulated based on these. It is confirmed that the errors of the simulation results could be reduced by considering the effects of small scale irrigational hydraulic structures and the reliability of the simulation results improved greatly.

Immigrant farmers work in various social and economic fields of activity, settling in their rural community. In this study, I inquired into the way of acting of immigrant farmers, based on the texts which were made in the precedent studies. The texts were transcriptions that were made by interviews with immigrant farmers. I classified immigrant farmers' activities into 8 groups that were related to; farming, nonfarm business, off-farm business, volunteering, participating in community organization, lifelong learning, leisure and social interaction in everyday life. And, I tried to capture the characteristics and meanings of those activities. The implications from this analysis are as followings: 1) most of immigrant farmers have small family farm so that they need nonfarm or off-farm jobs, 2) pluri-acivities of immigrant farm households can contribute to their community's economic viability, 3) their economic activities should be observed carefully in the perspective of self-help approach in community development as well as farm households' livelihood strategy, 4) immigrant farmers have many difficulties to participate in community, nevertheless community participation will improve the social capital, 5) gender-sensitive policy should be developed.

This these studies on SiJo to be published Dongkwang magazine. Dongkwang magazine was published from 1926 to 1933 but in the concrete it proceeded for three years two month. It was published a little SiJo and SiJo would reflected a phenomenon of society and a character of literature. A representative characters of the Si-Jo in substance at that time was summed up three. First it described a warmth of farm village. Expecially make full use of a sensuous description expressed a landscape of farm village. Otherwise it revealed a life of austerity in farming area. Second it reflected a phenomenon of return to their home village. People who was familiar with their country loved to come back their old home. To relax their mind and body they came back home and they pursuit romantic life. Third it was a poetry of historical retrospect. Although their country was colonial situation they longed fot their country's independence. Because of this anxiety they expressed their heart by means of old sijo. Mainly using old castle, ring, historic site they revealed a hidden feelings thst they had. It was a sorrow, an eager, remembrance etc. In spite of a poor surroundings they sang hope, romance, an possibility of independence. and so SiJo reflected the phases of the times.

In order to establish a labour-saved and environment friendly paddy rice system in southern Korea, no-tillage paddy system was proposed and investigated from 1992 to 1993. Basically this system includes a complete return of crop residules into the soil, and zero-tillage. In an effort to minimize labour requirement in rice farming, several cultivars were directly sown and grown under the system and the characteristics of the growth and yield potential of the cultivars were compared with those grown in an ordinary paddy soil. Joryeongbyeo, Dongjinbyeo, Daeyabyeo and Calose rices showed high level of seedling establishment in the no-tillage padddy system. However, the value was significantly lower than in those of the cultivars direct-sown in an ordinary tillage paddy condition. The rice direct-sown and grown under the no-tillage paddy system showed significantly decreased number of tillers per square meter and plant height, but increased ripened grains. The lodging-related characteristics of rice plant, such as band breaking weight, the length of top 3rd ∼4th internodes, the height of weight center, and lodging index, were observed positive aspects in cultivars such as Hwasungbyeo, Hwayongbyeo, Joryeongbyeo, Calose and Calose 76 and being considered adaptable to direct-sown under the no-tillage paddy system.

There are a number of prior studies on the poverty experience of Korean women, but little is known about the poverty experience of Korean elderly women in the U.S. The purpose of this study is to examine the poverty experiences of Korean elderly women who immigrated to the U. S. Qualitative case study methods were used to achieve these research objectives. Three Korean elderly women living in Oakland of California who received Supplemental Security Income (SSI) from the U.S. federal government were included in the study. The data were collected by conducting a total of six meetings per participant, and the researcher read the consent form directly to the participants and obtained a hand-written signature. The analysis and interpretation began by repeating the interview transcript several times, and the repeated keywords were to be understood in the context, focusing on time, space, and relationships with other people. The contextual understanding of Korean elderly women's experiences in poverty was interpreted in three dimensions: extending poverty in their mother country, double torture as female immigrants, and limiting labor due to aging and diseases. Before moving to the U.S., they had a difficult livelihood by farming and one of them had to live in poverty due to the bereavement to her husband. But even after moving to the U.S., they have continued to live in poverty. As female immigrants with low education and no special skills, they were incorporated into the periphery of the labor market in the industrialized U.S. and were forced to make a living with low wages. Korean elderly women were unable to return to the labor market in the surrounding areas due to aging and diseases, and were continuing their impoverished lives relying on SSI. From the findings, we discussed the role of the Korean immigrants community as a way to improve the quality of life for Korean elderly women in the U.S.
