Purpose of this research is to identify the variables that influence satisfaction level of the farmers when it comes to their every day life in the farms. Through this identification this research searches for ways to vitalize farming communities accordingly. For this research, 18 regions in 16 cities and provinces in the nation were selected, and 505 farmers who live in those regions were studied. As for the data analysis, One-Way ANOVA was used to identify the difference found in the satisfaction level of the farming community’s residents and related variables depending on the type and size of farming. The results are as follows. First, farmers who are engaged in the water field farming manifested high satisfaction level when it comes to the cultural activities and hobbies. As for the farmers who are engaged in the farming of crops for special use, they were satisfied with the ‘cultural resources of the town’, ‘convenience of the town’s common facilities’, ‘natural environment’, and ‘income.’ As for the farmers who raise fruits, they were satisfied with the ‘access to the public media’, and ‘use of commercial facilities.’ And the farmers who raise horticulture at facilities are satisfied with the ‘stability of the town’. Second, satisfaction level of the farms who farm on land between the sizes of 2 to 3ha was higher than that of the farmers who farm on the land of different sizes. 본 연구는 농촌주민들의 영농 유형 및 규모와 생활만족도와의 관계를 밝히고자 하는데 그 목적이 있다. 이를 통해서 농촌 주민들이 농촌지역에서 생활할 수 있는 이상적인 생활여건을 구축하여, 농촌 지역 활성화 방안을 모색하고자 한다. 본 연구의 모집단은 전국 16개 시․도, 18개 지역이며, 농민 505명이다. 자료의 분석은 영농유형 및 영농규모에 따라서 농촌생활 만족도의 차이를 알아보기 위해서 일원변량분석을 사용하였다. 이 연구에서 나타난 연구결과는 다음과 같다. 첫째, 수도작 농사를 짓는 농민들은 ‘문화취미생활’만족도가 높은 것으로 나타났고, 특용작물 농사를 짓는 농민들은 ‘마을 문화자원’, ‘마을공동시설 편의성’, ‘자연환경’, ‘소득’에 만족하는 것으로 나타났으며, 과수 농사를 짓는 농민들은 ‘대중매체 접근성’, ‘상업시설 이용’에 만족하는 것으로 나타났다. 그리고 시설원예 농사를 짓는 농민들은 ‘마을 안정성’에 만족하는 것으로 나타났다. 둘째, 영농규모에 대해서는 영농규모가 2~3ha 정도를 짓는 농민들의 경우, 마을문화자원, 대중매체접근성, 주거시설 편의성, 마을 안정성, 사업시설 이용, 마을공동시설 편의, 자연환경, 의료시설 이용 등에 대한 만족도가 높았다. 3~5ha의 경우에는 교육환경, 소득에서 만족도가 높은 것으로 나타났다.

The purpose of this study was to contribute to the establishment of quality improvement program of farm products and processed food, and to provide the direction of consumer education. A survey was conducted to figure out the differences in the consumer perception of farm products and processed foods according to age group and education level. From the citizens in Tague area, 509 housewives were selected as sample subjects by stratified random sampling procedure. It appeared the main criteria for purchasing farm products was significantly different among age group. Most of consumers(84.5%) thought that food safety of farm products did not belong to safe level. The way to distinguish imported farm products was significantly different among education level. While most of consumers(79.4%) check up the place of origin, the tendency was significantly different among education level. Higher educated group utilized labelling system for the place of origin more often than others to distinguish foreign products. Perception on the farm-brand processed food products was significantly different among age group and education level : it appeared that the younger age group and higher educated group tended to purchase more farm-brand processed food products than other groups.

Estimation of Instantaneous Sea Level Using SAR Interferometry

Sang Wan Kim,Joong Sun Won 大韓遠隔探査學會 2002 大韓遠隔探査學會誌 Vol.18 No.5

Strong and coherent radar backscattering signals are observed over oyster sea farms that consist of artificial structures installed on the bottom. We successfully obtained 21 coherent interferograms from 11 JERS-1 SAR data sets even though orbital baselines (up to 2 km) or temporal baselines (up to 1 year) were relatively large. The coherent phases preserved in the sea farms are probably formed by double bouncing from sea surface and the sea farming structures, and consequently they are correlated with tide height (or instantaneous sea level). Phase unwrapping is required to restore the absolute sea level. We show that radar backscattering intensity is roughly correlated with the sea surface height, and utilize the fact to determine the wrapping counts. While the SAR image intensity gives a rough range of absolute sea level, the interferometric phases provide the detailed relative height variations within a limit of 2π (or 15.3 cm) with respect to the sea level at the moment of the master data acquisition. A combined estimation results in an instantaneous sea level. The radar measurements were verified using tide gauge records, and the results yielded a correlation coefficient of 0.96 with an r.m.s. error of 6.0 cm. The results demonstrate that radar interferometry is a promising approach to sea level measurement in the near coastal regions.

An Analysis Regarding Trends of Dualism in Korean Agriculture

Jae-Hoon Sung,Sung-Hwi Woo 한국유통과학회 2017 The Journal of Industrial Distribution & Business( Vol.8 No.6

Purpose – The structural changes of Korean agriculture are complex due to heterogeneous production processes and farms’ features. This study analyzed trends of dualism in Korean agriculture over the period 2000-15 based on farm-level data to clarify the specific trends of dualism in terms of farm income, farm-size, and farm operators’ age. From the results of this study, we would be able to understand the features of structural changes in Korean agriculture more profoundly. Research design, data, and methodology – We incorporated farm-level data in South Korea: Agricultural census and Farm household economy survey. As measures of inequality, we used size-weighted quantiles, and normalized Gini coefficients as well as mean and conventional quantiles. The size-weighted quantiles are more robust to changes in the number of small farms, but they are more sensitive to changes in the distribution of farm-size. Thus, they would be more useful to identify trends of dualism of Korean agriculture. Results - The results show that the farmland distribution of crop farms became more skewed and dispersed. However, the herd distribution of livestock farms became more concentrated. To be specific, their mean and 1st quantile increases more rapidly than their size-weighted 2nd quantile and size-weighted 3rd quantile. Gini coefficients of livestock farms regarding their herd distribution decreased by 0.1 on average. In the case of income distribution, the results indicate that the polarization regarding farm household/agricultural/non-agricultural income became more severe. However, we also found that the distribution of transfer income became concentrated continuously. The results imply that transfer income including subsidies would decrease farm income polarization. Lastly, during the study periods, Korean farms were aging over time, and age distribution of them more concentrated. Conclusions – The structure of Korean agriculture has been changing, even though the absolute size of it decreased over time. Land (herd) distribution became more dispersed (concentrated). Inequality regarding agricultural income became more severe, and it made farm household income more polarized even though transfer income would decrease income gaps among farms. Lastly, farms continue to age regardless of farm types and this might affect the structural changes in Korean agriculture in the future.

This study was conducted to analyze factors affecting acceptance of smart farm technology. Smart farm technology is rapidly being introduced to agriculture in accordance with the progress of the 4th Industrial Revolution, but research on this is still little. Therefore, in this study, based on the unified theory of acceptance and use of technology (UTAUT), a research model reflecting the characteristics of smart farm technology was constructed. To test this, empirical analysis was performed. A survey was conducted for students in smart farm technology education and adult male and female farmers who are currently planning to operate smart farms. Valid 204 sample were used for analysis. The hypothesis test was based on multiple regression analysis using SPSS 24 statistical package. For the mediating effect and moderating effect, Process Macro 3.4 based on the regression equation was used. The results of testing the hypothesis are as follows. First, in the causal hypothesis test, it was shown that performance expectancy, social influence and price value have a significant positive effect on the intention to use smart farm technology. On the other hand, effort expectancy, facilitating conditions were not tested for a significant influence on the use of smart farm technology. As a result of analyzing the mediating effect of trust, it was found that trust plays a mediating role between performance expectancy, effort expectancy, social influence, facilitating conditions, price value and intention to use smart farm technology. In particular, the effort expectancy has not been tested for a direct significant effect on intention to use smart farm technology, but it has been shown to have an impact through trust. Trust was found to be a full mediating between the effort expectancy and the intention to use the smart farm technology. The current IT level of prospective users has been shown to play a moderating role between performance expectancy, facilitating conditions and intention to use smart farm technology. In particular, the IT level was found to strengthen the relationship between performance expectancy and intention to use smart farm technology. Based on the results of these studies, academic and practical implications were suggested.

Background: The poultry red mite, Dermanyssus gallinae, is a serious problem in the laying hen industry worldwide. Currently, the foremost control method for D. gallinae is the implementation of integrated pest management, the effective application of which necessitates a precise monitoring method. Objectives: The aim of the study was to propose an accurate monitoring method with a reliable protocol for caged-layer poultry farms, and to suggest an objective classification for assessing D. gallinae infestation on caged-layer poultry farms according to the number of mites collected using the developed monitoring method. Methods: We compared the numbers of mites collected from corrugated cardboard traps, regarding with length of sampling periods, sampling sites on cage, and sampling positions in farm buildings. The study also compared the mean numbers of mites collected by the developed method with the infestation levels using by the conventional monitoring methods in 37 caged-layer farm buildings. Results: The statistical validation provided the suitable monitoring method that the traps were installed for 2 days on feed boxes at 27 sampling points which included three vertical levels across nine equally divided zones of farms. Using this monitoring method, the D. gallinae infestation level can be assessed objectively on caged-layer poultry farms. Moreover, the method is more sensitive than the conventional method in detecting very small populations of mites. Conclusions: This method can be used to identify the initial stages of D. gallinae infestation in the caged-layer poultry farms, and therefore, will contribute to establishment of effective control strategies for this mite.

백승희,남인식 한국유기농업학회 2018 韓國有機農業學會誌 Vol.26 No.4

This study was conducted to establish scores according to the importance levels of each HACCP evaluation item in cattle farm. The importance levels and score of each HACCP evaluation item was derived through the non-compliance rate and severity levels of hazard. In order to change the score criteria according to the importance of each HACCP evaluation item, we analyzed the importance of each HACCP evaluation item by using the portfolio mapping method according to the occurrence frequency and severity levels of hazard. The scores were classified into 3 point, 2 point, and 1 point, respectively, by classifying the importance of each category as ‘high’, ‘middle’ and ‘lower’. Accordingly, we have established a now scoring system of each HACCP evaluation item through this study. Through the result of this study, the objectivity of the comparative evaluation was verified by implementing the currently used HACCP evaluation item to the cattle farm. In conclusion, Implementation of the result of this study to cattle farm may help to increase the objectivity and also improve more safety and hygienic cattle management and raw milk production.

Design Approach with Higher Levels of Abstraction: Implementing Heterogeneous Multiplication Server Farms

Moon, Sangook The Korea Institute of Information and Commucation 2013 Journal of information and communication convergen Vol.11 No.2

In order to reuse a register transfer level (RTL)-based IP block, it takes another architectural exploration in which the RTL will be put, and it also takes virtual platforms to develop the driver and applications software. Due to the increasing demands of new technology, the hardware and software complexity of organizing embedded systems is growing rapidly. Accordingly, the traditional design methodology cannot stand up forever to designing complex devices. In this paper, I introduce an electronic system level (ESL)-based approach to designing complex hardware with a derivative of SystemVerilog. I adopted the concept of reuse with higher levels of abstraction of the ESL language than traditional HDLs to design multiplication server farms. Using the concept of ESL, I successfully implemented server farms as well as a test bench in one simulation environment. It would have cost a number of Verilog/C simulations if I had followed the traditional way, which would have required much more time and effort.
