  • The socio-network activities for regional governments, agricultural research institutes, developing agencies and policy makers of any countries are very crucial and important to take into account the root cause of current problems faced by farmers. The survey was conducted in South Korea during the period January, 2008 to August, 2012 in order to shed light on prevalence of different diseases on watermelon in different regions and to better understand farmers' knowledge and perceptions for following watemelon's growing procedures and practices. A total of 590 cases were reported on 573 watermelon growers with highest 87.1% in Jeonbuk, 4.7% in Jeonnam, and 8.2% in other regions such as Gyeongbuk, Gyeongnam, Chungnam, Gwangju, Gyeonggi, Daegu, Gangwon, Changwon and Seoul. The maximum percentages of cases recorded were related to diseases and insect pest (38.6%) followed by physiological disorder (29.7%), cultural practices (18.8%), soil and fertilizer (9.0%), herbicide (2.9%) and others (1.0%). It was observed that the manifestation aspects of the diseases were changed due to increasing in proportion of 'in-facility' cultivation to 12,995 ha compared to 'open-field' cultivation (2,722 ha). The present survey revealed the necessity to reduce the damages incurred at watermelon farms as soon as possible through the breeding program to develop resistant cultivar, use of pathogen-free propagating plants, and efficient prevention of pathogen by regular monitoring of watermelon plants at farms.

  • Korean ginseng is the one of the most famous medicinal herbs globally and has long been a representative item of East Asian trade, including across China and Japan. Since Joseon (1392-1910) ginseng trade was entirely controlled by the state, The Veritable Records of the Joseon Dynasty are a valuable resource that can shed light on the history of the ginseng industry at that time. By studying the subsection "The Veritable Records of King Sejong" (世宗實錄), when ginseng was used even more widely, we assess the purpose and scale of its trade in the 15th century, identify its original listing in the geographical appendix, develop a distribution map, and explore similarities to current ginseng cultivation areas. During the reign of King Sejong (1418-1450), ginseng was sent to China as a tribute 101 times, with a combined weight of 7,060 kilograms, with less than one-third of that amount given to Japan and Okinawa. It was used to cover the travel expenses of foreign envoys and servants, but this can be seen to gradually decrease after the regnal mid-term, primarily due to a decrease in the amount of ginseng being collected. At the time, there were 113 areas of naturally growing ginseng as listed in the records' geographical appendix, including 12 recorded in the 'tributes' category: Yeongdeok-gun, Yeongju, and Cheongsong-gun in Gyeongsangbuk-do; Ulju-gun and Ulsan in Gyeongsangnam-do; Jeongeup, Wanju-gun, and Jangsu-gun in Jeollabuk-do; Hwasun-gun in Jeollanam-do; Goksan-gun and Sinpyeong-gun in Hwanghaebuk-do; Jeongju and Taecheon-gun in Pyeonganbuk-do; and Jaseong-gun and Junggang-gun in Jagang-do. A total of 101 places are recorded in the 'medicinal herbs' category, located throughout the mountains of the eight Joseon provinces, except the islands. In comparison with current ginseng cultivation sites, many of these historical areas are either consistent with or adjacent to contemporary locations. The geographical appendix to "The Veritable Records of King Sejong" was compiled in the early days of the king's reign (1432) when there was a lot of wild ginseng. The appendix is a valuable resource that indicates the possibility of growing ginseng on the Korean Peninsula in the future. The apparently natural habitats in the south, where ginseng is not currently cultivated, could be candidates for the future. Moreover, areas in the north where ginseng has not been grown, except Kaesǒng, could be a good alternative under sustainable inter-Korean exchange should cultivation sites move north due to climate warming.

  • There have been groves, in many cases, along with hedgerows and remnant forests around a traditional Korean village. A village grove is very closely connected to the life of residents. Sometimes it was a holy place where important village festivals were held, and became a resting place for farmers, especially in sunny summer. As a matter of fact, it is noted that traditional Korean village groves had been fostered for many purpose as religion, Confucianism, scenery, sanitation, traffic guard, public security, agriculture, hunting, and military and public uses were included in Chosun Govemor General(1938). Village groves were usually located at the outlet of watershed inside which a village was built. In addition, village groves used to be established along part of mountain ranges, streams and streets. A unique type of village grove, called bibosoop was fostered especially where the outlet of watershed was largely opened. In other cases, it was placed where a part of mountain range was relatively low, or where village residents were likely to see ugly objects such as a huge cliff, stony upland with an unvegetated area and the like(Kim and Jang 1994). In a sense, a sheltebelt is a sort of bibosoop as it is a landscape element to complement places that are exposed to strong winds. However, it is comparable to other typical bibosoop that is situated at a topographically very specific zone of watershed. In this paper, we will address potential functions of Korean village groves from a perspective of modern landscape ecology and show current status of some remnants, based on preliminary surveys. A village grove functions as barrier or filter of objects such as water, nutrients, and other elements and habitat of wildlife (park et al. 2003, Lee 2004). The village grove slows down the flow of water and air, maintains soil moisture an hinders soil erosion, enabling cultivation of crops and bringing up creatures nearby. It contributes to enhancing biodiversity. Birds rest on shrubby and woody trees of the element. Presumably, other organisms may also inhabit the village groves and take advantage of it when those move from a forest patch to others. Emerging insects acclimate themselves in the shade of the green space before they fly to sunny air. Besides the village grove acts as a component of agroforestry system as leaf litter is shed from a grove to an asjacent agricultural area, and transformed into green manure(Lee 2004). By the way, many of the landscape elements were destroyed or declined in Koea during the past several decades. The losses have been parallel or linked to environmental degradation. Unfortunately, we have a little reliable data as for how many groves have disappeared in Korea until now. There has been no complete census on the village groves in Korea, and the viewpoints of survey were to a degree different depending on surveyors. So, it is difficult to analyze the temporal and spatial change of village groves. Currently, national inventory data of Korean village groves are available in three reports. We reviewed the locations of village groves and arranged those according to the present administrative units, DONG. With the limited data, we found that at least 484 of village groves were recorded in South Korea. Among all provinces, village groves were most in Gyeongsanbuk-Do Province and least in Chungcheongbuk-Do Province(Table 1). This is a preliminary report prepared while some quantitative data regarding functions and lossers of the village groves are being collected. More detailed data will be introduced in the near future.

  • This paper aims to shed light on the structure of "Eonji[言志]" to demonstrate that it is a song with educational purposes, which is evident in its meaning and constitution. Based on various records of the epilogue and from the texts handed down several generations, it is clear that is an educational song that describes the life of ascholar and the core of knowledge as considered by Lee-Huang. Therefore, the meaning contained in Eonji[言志] is closely related to Lee-Huang's thoughts and it reflects the Confucian way of life. In the 4thphase, Pimi-ilin[彼美一人] of Eonji[言志] states that self-learning and serving the king can be carried out concurrently. The 5th phase of Eonji[言志] describes the anxiety of the lord for the wiseman and urges people to live a life full of consideration. This shows that one should not disregard the fact that a wise man's scholarship and life can contribute to the politics of the real world, even if the wise one chooses to lead a life of seclusion; even when the wise man enters the word of politics, his behavior and traits must not deviate from the calm course of self-cultivation in nature. The structure of Eonji[言志] and its different phases comprising nature, scholarship, and education deal with the following matters: "the meaning of retirement into nature (1stphase)," "nature+the practice of scholarship (2ndphase)," "scholarship+the practice of education (3rdphase)," "nature+the stance of scholarship (4thphase)," "scholarship+the stance of education (5thphase)," and "the beauty of nature+idea of scholarship and education (6thphase)."
