This paper is the design for the welfare robot of apple artificial pollination by a survey for 25 elders' needs of Daegu-Gyeongbuk rural region. The results are summarized as follows. 1) In the apple farms of the region, most of farmers are the couples of 50 years thru 70 years to plant the apple trees only. The apple farm requires the senior farmers lots of painful works including their bone and muscle system problem to result in safety accidents. 2) For the aging progress of rural area, the senior farmers spend lots of labor hours and cost to do artificial pollination, a proper deletion of small fruits, and a speed spray, etc.. Most of them agree to the development of the welfare robot for an apple artificial pollination. 3) The survey results could be applied to the conceptual design in the users' point of view. Therefore, they are used as the important effects for the detail design and commercial design to develop the welfare robot for the rural seniors.

견우와 직녀의 사랑 이야기가 얽혀 있는 두 별은 여름철을 대표하는 별들로서 중국 문화권에서는 지난 수 천 년 동안 매우 인기가 높은 별이었다. 두 별은 중국의 춘추전국시대의 노래를 모아 놓은 시경(詩經)에 이미 등장하고 있고, 서기 408년에 조성된 고구려의 덕흥리 고분 속에 있는 벽화에도 그려져 있다. 고려시대에는 이 별들에 대한 국가적인 제사를 지냈으며, 조선 시대에는 칠월칠석에 국왕이 신하들과 어울려 잔치를 베풀고 칠석시(七夕詩)를 지어서 책으로 편찬하는 일도 있었다. 한편 견우성은 주로 농사와 관계된 별점을 가지고 있었고, 시각제도와 긴밀한 관계가 있는 28宿(수)의 하나였으므로 천문학자들이 지속적으로 관심을 갖고 관측한 별이다. 그러한 관측의 결과는 고려사, 조선왕조실록, 승정원일기 등에 다수가 남아 있다. 그런데 동양 천문학에서 이미 널리 다루어졌던 문제 가운데 하나는, 바로 이 문학적 견우성과 천문학적 견우성이 일치하지 않는다는 것이다. 지금 일반 시민들에게 견우성은 독수리자리의 알테어(Altair)로 알려져 있다. 그러나 모든 사서와 고대 천문서 및 천문도가 지칭하는 견우성은 염소자리의 다비(Dabih)라는 별이다. 견우성이 28宿(수)의 하나라는 사실은 그 별(별자리)이 황도와 백도 근처에 있어야 함을 의미한다. 따라서 알테어는 적위가 높아서 도저히 28宿(수)에 속할 수가 없다. 게다가 알테어는 은하수 속에 들어가 있으므로, 견우와 직녀가 은하수를 사이에 두고 마주보고 있다는 일반적인 설화와도 어긋난다. 그럼에도 불구하고, 현재 대다수의 서적과 매체, 그리고 일반인을 대상으로 한 행사와 천문관에서 상영되는 프로그램들에는 모두 알테어를 견우성으로 하여 설명하고 있다. 이러한 불일치는 상당한 혼란을 초래하고 있는 상황이다. 이 연구에서는 이러한 불일치가 천문학적인 견우성과 인문학적인 견우성의 불일치로 보고, 이 문제를 실증적으로 접근해 본다. 즉, 고려사, 조선왕조실록, 승정원일기에 실려 있는 견우성 엄폐 관측 기록을 조사하여 한국사에서 전문 천문학자들은 어느 별을 견우성이라고 보아왔는지 알아보고, 또한 일반인들이 지은 시문에는 어떤 별을 견우성으로 여겼는지 고찰한다. 아울러 역사적으로 이 문제에 대한 선인들의 생각을 짚어보고, 중국과 일본의 학자들은 이 문제를 어떻게 바라보고 있는지를 살핀 다음, 마지막으로 현실적으로 이 문제를 어떻게 해결할 수 있는지 고찰해 본다.

The purpose of this study is to estimate the biodiversity conservation value of Heory stock in Sun-Cheon. Expected values of residents' Willingness To Pay (WTP) was estimated using Contingent Valuation Method (CVM) which is the most popular method in estimating conservation values of biological diversities. Three different estimation methods were used in statistical estimation, and the results were different from each other. Results of statistical analysis show that the expected value of WTP in logit model is highest, 5,772 Won per month. Those of A model which conducted OLS estimation using open ended questionnaire and B-1 model which conducted OLS estimation using dichotomous choice questionnaire were 1,978 Won per month and 2,391 Won per month respectively. The average expected value of WTP from three model was 3,380. This average value was expected to reduce methodological biases.

The effect of seasonal variation on social statistic data is important. But in health subcenter in rural areas the effect has not been well known. To determine the seasonal index of medical needs in rural communities, the monthly number of patients were analyzed from Jan. 1994 to Dec. 2000. Seasonal index were calculated using 12 months moving averages and median value of each data. The number of patients excluding common cold were analyzed by same method. The seasonal index from Jan. to Dec. were 0.96, 1.08, 1.23, 0.83, 0.82, 0.75, 1.01, 0.99, 1.02, 1.05, 1.13, 1.13. The seasonal index of patients excluding those with common cold were 0.94, 0.90, 1.42, 0.94, 0.91, 0.77, 1.13, 0.92, 0.84, 1.07, 1.10, 1.16. In a rural area, medical needs are decreased on spring and early summer and increase in winter, and that are the influence of rural area.

The purpose of this study is to investigate and analyze the relationships between tidal cycles, surface landforms, and sediments of tidal flats and their resident life. The study areas are Uengdo Ri in the Garolim Bay with wide the mud flat, Doou Ri in the Youngwang tidal flat which is developed sand flat and salt field, and Gomso Bay which is developed aquaculture industry. For resident around tidal flats, sea working takes precedence over farming, and main earnings gets from tidal flats. Resident life around the tidal flats is deeply related to tidal cycles, and low water level of spring tide becomes, they are most active and get more earnings than usual day, so it seems to be periodic markets. It is usually developed shellfish aquafarms in the mud flat, the stow net fishery in the sand flat, and salt fields in the mixed flat near the coast. Also a tidal flat has specialization of economic activity, and is divided into salt field and fish-farming in the supratidal zone, shellfish aquafarm in the intertidal zone, and oyster and porphyra culture in the subtidal zone.

Ancient mix seeding that started in China and generated in Korea is one of the methods of securing foods against natural calamities. The history of this technology was excerpted and presented from Chinese agricultural books as "Jeminyosul"(closely one upon the other 5C), "Wangjungnongseo"(from 1313) and Korean agricultural books as "Nongsajikseol"(from 1429), "Hanjeongrok"(from 1610), "Saekyeong" (from 1676), "Jeungbosanrimkyeongje"(from 1766), "Kwanongsocho"(from 1799), "Rimwonkyeongje" (from 1843). In this study, we suggested new environment-friendly agricultural technique to save labors using ancient mix seeding principle, which is seeding different varieties rice without fertilizer and agricultural pesticides. It is essential prerequisite to have the process such as injecting Azolla, no-tillage direct and broadcast seeding with multiple varieties of rice. Based on the results of previous studies, we evaluated the practical validity.

This autobiographical narrative interview study aims at exploring how A, one Korean 82-year-old female farmer strived vigorously to learn by herself and to teach her children (4 boys and 3 girls) despite the fact that she was not afford to pay tuitions on time. From 40 times of interview-data three major findings emerged: (1) A learned how to read Korean Japanese and Chinese characters and how to calculate at a free-of-charge teaching center although her father didn't approve of her learning; (2) A tried very hard to earn money inside and outside home to support her children's education, organizing many mutual fraternity meetings to seek mutual financial support, selling mostly farm products as well as farming almost all day and everyday; (3) Although it was so hard to educate three daughters, A was proud of the fact that she was able to put her second daughter to a high school with a promise to pay her tuition later. Some implications of the findings are added.

Gonggeomji, located at the outlet of intermontane basin in the upper reaches of Dong River, is known as being constructed in the late Unified Silla Dynasty. Extensive wetlands were developed before the construction of embankment at Gonggeomji and very compact silty layers were deposited during dry seasons. Paniceae was cultivated on a dry field in the basin during the early Bronze and Iron Ages. Although it is supposed that agricultural activities on a paddy and dry field prevailed during the Three Kingdoms Age, the indicating layer was not found. As the construction of the embankment, Oryza sativa as well as Paniceae were cultivated in the basin at the same time. The climates during the early Bronze are cool and Iron Ages are estimated to be generally warm. From the late Unified Silla Dynasty and middle Goryeo Dynasty when the embankment was constructed, it was still warm, and then, shows alterations between cool and warm conditions. Since the late Goryeo Dynasty, it gradually became cool.

Amid the global population growth and climate change, high-tech smart farm technology that combines agriculture and ICT is actively being researched in Korea to solve sustainable crises such as declining population of agricultural and livestock industries. Existing smart farms are growing mainly on crops with low price competitiveness. Food consumption structures are becoming more sophisticated and diverse, and as agricultural consumption patterns change, the smart farm system also needs to be optimized for growing high-value special crops. To this end, an integrated ICT management system was designed and implemented by establishing a containerized smart farm environment specialized in growing sprout ginseng. Through this, it is possible to implement high-tech agricultural production and lead new future convergence industries through the convergence of ICT, agriculture, and the latest technologies and farming.

In this paper, the purpose of this study is to melt the process of returning to farming through games and settle down in a stable manner to ensure that there are no more prospective young farmers who wish to return to farming but cannot proceed with their dreams due to various barriers of reality. The game was designed to develop in the order of fields, greenhouses, automation systems, and smart farms, and to grow the crops they want at the early level, and added a community system to highlight that rural areas are community life, not individualistic life. Support benefits or information provided by local governments or governments were inserted into the community system so that prospective farmers could naturally access the information.
