This research investigated the retired elderly who had moved to rural areas. The propose of the study was to examine the point at which there must be a difference in the patterns of a return to farming and determine the actual condition of their preparations for migration. This study had surveyed 408 seniors who wereare over 50 years old and had moved to rural areas after their retirement and analyzed the data by the SPSS PC 11.0 program. The results were as follows. First, the relevancy of U-turn, J-turn, and I-turn types that were affected by social demography was found to be dependent on their education levels and family patterns. Second, the actual conditions of the process of preparation by the types of a return to the farming were different according to the motivation and preparation fund. Nevertheless, the most important factor was the influence of their spouses. Third, the actual conditions of the process of adaptation by the patterns of a return to the farming showed no difference between the degree of efforts of the social supportand elevation of the friendship among the neighbors. The recognition of rural life problems were more acquainted towards the area of farming life. Among the 6 problem areas, leisure, health care, and economic problems were highly considered.
With the development of society, changes in the family structure of China's residents and the increase in family income, parent-child travel has gradually become a new hotspot for tourism consumption. It is important for tourism marketers to understand the needs and motivations of parent-child travelers. This study explored the push and pull motivations of parent-child travelers by conducting a questionnaire survey of 290 travelers to parent-child farms and validated the path relationships between push and pull motivations, experiences and behavioral intentions. The result indicated that: 3 push factors were derived from the factor analysis of 13 push items and were named as 'For children & Family', 'Escape & Relax', and 'Socialization'; 3 pull factors were derived from the factor analysis of 11 pull items and were labeled: 'Facilities & Safety', 'Theme activities', and 'Environment'. Through sub hypotheses testing, the results show that push-pull motivation of parent-child travelers has a positive effect on their experience(4Es) for attending. 'Esthetics Experience' has the highest effect on the parent-child travelers' behavioral intentions, followed by 'Education Experience' and 'Entertainment Experience'.
Theoretically, it is said that economies of scope can be realized in the cropelivestock cycling organic farming. Thus, it is also used as the principle of organic farming. However, it is difficult to find the cases of the empirical analysis of it in Korea. In that sense, this study is meaningful in that it analyzed the agricultural data of case farms of obtaining the approval of both organic agricultural products and organic animal products and practicing cycling farming for 4 years and tested the hypothesis. This study measured economies of scope by using the actual measurement value and estimation value farming performance statistics for 4 years of case farms. This farmhouse conducted nutrient cycling in the farm like self-manufacturing and injecting organic agricultural byproduct and wild grass as organic livestock feed and fermenting organic livestock manure to organic compost to return it 100%. The results can be summarized as follows: According to the result of cycling farming of combining and producing organic agriculture and organic livestock, economies of scope were found to be realized in this case farmhouse. That is, although not strong, EOS>0, there were economies of scope. The measurement value appeared as 0.0722, 0.00378, 0.04667 and 0.13127 in 2012, 2013, 2014 and 2015, respectively. It was improved as time passes and the scale gets smaller. Therefore, in order to further improve economies of scope, there should be measures of reducing duplication costs between agriculture-livestock as low as possible and lowering the production cost of organic feed. That is, there is a need for the management strategy to adjust the import function and cost function according to the change in management paradigm and cropping system.

This study investigated the effects of urban farm program on the participants' sense of community. Three public urban farms in Seoul were selected and surveyed. The results were as follows: First, the effects of the urban farm program on the sense of community were verified by a multifaceted analysis. There were significant differences in the interaction and sense of community between urban farms with and without regular programs. Program participants showed higher level of activity, interaction and sense of community compared to non-participants. Program participation was the most important factor in the path analysis. Second, the number of participating group, residential ownership and duration were important factors in the sense of community. This implies that urban farm programs should target house owners with long duration, in particular socially disadvantaged classes such as single-family and elderly household. Third, diverse cultural programs related to the regional society gained higher satisfaction than the simple agricultural educational programs.

African swine fever (ASF), caused by the ASF virus, a member of the Asfarviridae family, is one of the most important diseases in the swine industry due to its clinical and economic impacts. Since the first report of ASF a century ago, ample information has become available, but prevention and treatment measures are still inadequate. Two waves of epizootic outbreaks have occurred worldwide. While the first wave of the epizootic outbreak was controlled in most of the infected areas, the second wave is currently active in the European and Asian continents, causing severe economic losses to the pig industry. There are different patterns of spreading in the outbreaks between those in European and Asian countries. Prevention and control of ASF are very difficult due to the lack of available vaccines and effective therapeutic measures. However, recent outbreaks in South Korea have been successfully controlled on swine farms, although feral pigs are periodically being found to be positive for the ASF virus. Therefore, we would like to share our story regarding the preparation and application of control measures. The success in controlling ASF on farms in South Korea is largely due to the awareness and education of swine farmers and practitioners, the early detection of infected animals, the implementation of strict control policies by the government, and widespread sharing of information among stakeholders. Based on the experience gained from the outbreaks in South Korea, this review describes the current understanding of the ASF virus and its pathogenic mechanisms, epidemiology, and control.

Bovine viral diarrhea virus (BVDV) is an RNA virus belonging to Pestivirus in the family Flaviviridae. BVDV has economic significance for the livestock industry because of its association with acute disease, fetal loss, and birth of persistently infected (PI) animals. This study aimed to investigate the BVDV infection rates in Korean native cattle farms in Jeju for further planning of a BVDV control program in the Jeju Province. BVDV antibodies and antigens were tested in 15,842 sera collected from 302 Korean native cattle herds between January 2014 and June 2017 using enzyme-linked immunosorbent assay (ELISA). Viral antigen was detected by reverse transcription-polymerase chain reaction from 60 sera that were antigen ELISA-positive. BVDV antibodies were found in 90.7% (274/302) herds and 61.1% (9,678/15,842) cows. BVDV antigens were found in 13.2% (40/302) herds and 0.4% (61/15,842) cows. The oldest animal group (> 8 years) exhibited the highest sero-positive rates (91%), while the youngest animal group (< 1 years) had the highest antigen positivity rates (0.52%). Of the 60 antigen-positive sera, BVDV types 1 and 2 were found in 36 and 12 sera, respectively. Additionally, six animals were considered to be PI as BVDV was continually detected in annual examination.

This study is to find the causes of the current situations of conflict between generations in regards to succession of their family farm, for the target group of graduates Korea National Agricultural College of the year 2008 and their parents. This study aims at finding a way of controlling and solving the conflicts, and of developing a course of education and training, so that through this process they can come to a rational conclusion to the conflicts that arise regarding succession of the farm, in a climate of harmony and peace. It is found that communication between parents and graduates has normally gone on well, but specific problems related to management of the farm are often present. Furthermore, there is often lack of trust and promise between the parties which often causes difficulties in preparation for the succession of the farm. On the basis of these observation, we have designed and implemented an education workshop and training, as a program in which parents and their successors participated. As a result, we found it to be very effective, but it was also found to be in need of some changes. The workshop is to be implemented in two separate stages. The first stage should focus on communication and trust between family members. Firstly, they are given the opportunity to share the list of concerns withone another, as an ice breaking activity. Secondly, they can present their own hopes or wishes. And lastly, they can communicate with one another in an effort to find resolutions that will be keep both parties satisfied. The second stage should be aimed at establishing agreements concerning succession of the farm in a harmonious and peaceful manor; the second stage is also an opportunity to discuss 'Farm management and succession'. The Korea National Agricultural College (KNAC) is in the pursuit of fostering agricultural CEO's for the future of Korea. KNAC is currently implementing a very unique system of interviews in which parents participate together with students, in order to help them make a plan for rational management of their farm and smooth succession of the farm. Although KNAC now has students present a blueprint of their own unique business plans as a graduation thesis, it is necessary for KNAC to complement this system with education and training regarding the succession of family farms. Furthermore, KNAC should also develop an education and training program that is separate for this purpose, and make it a regular course of study of KNAC in the future.

The symptoms of farmer's syndrome that occurred to Korean farmers are due to the specific characteristics of Korean agriculture, and the basic reasons are poverty and less-privileged rural cultural life originated from social and political conditions. Then the purposes of this study are to investigate farmer's syndrome of farmers and to get substantial data to make a strategy that could prevent diseases. The results are as follows: 1. The most common symptom was lumbago(83.0%) among the 7 kinds of symptoms of farmer's syndrome. And it was more common among women who deliver babies and also work house chores and 10 farms than men(p<0.05). 2. The numbers of symptoms of farmer's syndrome increased as age increases and, 71.4% of those aged 70-79 complained some of the symptoms. 3. The accident rate due to agricultural machine was significantly higher in men than women(p<0.05). By frequency contusion was the most common trauma, fall, fracture were the nexts, and the age group with highest accident rate(40%) was those aged 20-29. 4. To see the significantly correlated factors between faemer's syndrome and sociodemo graphic variables, the more the numbers of family members were, the more lumbago and the less heartburn occurred. And the less gross income was the more frequent nocturnal urinary frequency occurred, and the wider the farming land was the more frequent noctural urinary frequency occurred. 5. As result of correlation coefficient between the numbers of illnesses and sociodemographic variables, the larger the family was and the larger the farming land was the more illnesses the subjects had, and those without spouses had more illnesses.
The objective of this study was to investigate the accuracy of imputation from low density (LDC) to moderate density SNP chips (MDC) in a Thai Holstein-Other multibreed dairy cattle population. Dairy cattle with complete pedigree information (n = 1,244) from 145 dairy farms were genotyped with GeneSeek GGP20K (n = 570), GGP26K (n = 540) and GGP80K (n = 134) chips. After checking for single nucleotide polymorphism (SNP) quality, 17,779 SNP markers in common between the GGP20K, GGP26K, and GGP80K were used to represent MDC. Animals were divided into two groups, a reference group (n = 912) and a test group (n = 332). The SNP markers chosen for the test group were those located in positions corresponding to GeneSeek GGP9K (n = 7,652). The LDC to MDC genotype imputation was carried out using three different software packages, namely Beagle 3.3 (population-based algorithm), FImpute 2.2 (combined family- and population-based algorithms) and Findhap 4 (combined family- and population-based algorithms). Imputation accuracies within and across chromosomes were calculated as ratios of correctly imputed SNP markers to overall imputed SNP markers. Imputation accuracy for the three software packages ranged from 76.79% to 93.94%. FImpute had higher imputation accuracy (93.94%) than Findhap (84.64%) and Beagle (76.79%). Imputation accuracies were similar and consistent across chromosomes for FImpute, but not for Findhap and Beagle. Most chromosomes that showed either high (73%) or low (80%) imputation accuracies were the same chromosomes that had above and below average linkage disequilibrium (LD; defined here as the correlation between pairs of adjacent SNP within chromosomes less than or equal to 1 Mb apart). Results indicated that FImpute was more suitable than Findhap and Beagle for genotype imputation in this Thai multibreed population. Perhaps additional increments in imputation accuracy could be achieved by increasing the completeness of pedigree information.
Marine fish aquaculture has been introduced on the East sea since 1964. The production volume of the marine aquaculture has been increasing drastically since 1990 with the technological improvements and the introduction of new species. However, the increasing costs of feed, seedlings and medical supplies and the decreasing prices due to the increase in the imports and domestic production have decreased the profits in the aquaculture business. Futhermore, the damage from the natural disasters such as red tides and typhoons has accelerated the exit from the business. Even though managing abilities to overcome the business crisis caused by the above factors are required, business managers based on the small scale family businesses do not have enough managing abilities to deal with the difficulties in the business. On the other hand, advanced countries in the marine aquaculture such as Norway have reached the stage where the managing abilities of marine aquaculture are similar to those in the manufacturing industry. And the number of large scale aquaculture farms with developed technologies and advanced marketing strategies in those countries is increasing. Considering that the marine aquaculture in Japan under the similar fishery systems of Korea has developed the state-of-the-art management skills or lead to large scale management, it is difficult to expect the decrease in the production costs under the small scale family business in Korea and this will lead to the decreasing competitive advantage over the imported seafood. Therefore marine aquaculture in Korea needs to increase the economy of scale to acquire the competitive advantage. This study addresses the possibility of introducing the large scale aquaculture system in Korea by analysing the factors and process of leading to large scale businesses in the aquaculture in Japan.
