There is a growing need to understand how local, farm household, and elementary units are responding to changes in agricultural conditions due to increased internal and external agrarian conditions and increased uncertainty in agricultural management due to increasing FTA and climate change. Therefore, we analyze dynamics of changes through more detailed and precise gathering of information related to agricultural products and DB, and by analyzing the satisfaction level of the first year panel survey by constructing a producer panel for utilization in agricultural research and policy. A total of 500 farmers in the producer panel who mainly grow rice, garlic, onion, strawberry, apple were collected through questionnaires. The actual analysis used data from a total of 393 farm households, including 82 farms of rice, 51 farms of apple, 100 farms of garlic, 88 farms of onion and 72 farmhouses of strawberry. The distribution by age was similar to the distribution of rural ages in Korea, with 2.8% under 30s, 17.6% in 40s, 32.4% in 50s, 37.5% in 60s and 9.7% in 70s. Panel happiness and rural life satisfaction were examined using the 7 - point Likert scale and the analysis method was one - way ANOVA. The results showed that the happiness of garlic and strawberry cultivator was significantly higher than that of rice and onion cultivator. However, the satisfaction of rural life did not show any difference among the cultivars. As a result of difference verification about Agricultural Outlook and Crop-specific Outlook after 5 years, there was no difference between the crops in terms of prospects for Korean agriculture after five years, but a survey of industrial prospects for crops after five years showed that the rice growers have a significantly negative outlook compared to garlic, onion and strawberry growers, and garlic and onion growers have a more positive outlook than rice and apple growers As a result of verifying whether there is a difference in ages between the agricultural prospects and the industrial prospects by crops after 5 years, there was no difference between the ages of prospects for Korean agriculture after 5 years, However, in the survey on industrial prospects by crops after 5 years, 40s were more positive than 60s.

In this paper, we consider one-level rotation designs with finite rotation groups such that the design satisfies two basic requirements: all rotation groups are included in any given survey period, and overlapping rates depend only on the time lag. First we present the necessary number of rotation groups and a rule for the length of time the sample units are to be in or out of the sample to satisfy the requirements. Second, an algorithm is presented to put rotation groups to proper positions in a panel in order to include all finite rotation groups for any survey period. Third, we define an one-level rotation pattern which is invariant in the survey period and has useful properties in practical sense.

Objective: Understanding consumer perception of meat quality in developing countries is an important issue since consumer perception of quality could be highly variable. In the current study, consumers' purchasing preferences affected by marbling and perception of quality were evaluated in a survey study. Furthermore, consumers' preferences for degree of doneness were investigated using both survey and consumer panel studies. Methods: The study was carried out in two phases. Firstly, a survey was conducted in Adana Province, Turkey to collect data related to the attributes affecting consumers' meat purchase decision and consumers' degree of doneness preferences. In the second phase, boneless ribeye was used to investigate consumers' degree of doneness preferences in a consumer panel. In addition, proximate analyses of the samples were conducted. Results: The survey study using pictures of marbling illustrations indicated that higher degrees of marbling might be considered too fatty to be purchased by consumers. Consumers' perceptions regarding the relationship between marbling and beef quality further indicated that marbling might not be acknowledged as a cue of a higher quality meat. Nevertheless, the results of the importance of some attributes related to intrinsic and extrinsic quality cues showed that consumers were looking for the cues that indicated not only quality but also safety of the meat during meat purchase. The results of both survey and consumer panel studies revealed that consumers might prefer higher degrees of doneness while consuming meat since a majority of the consumers' preference of degree of doneness was at least well done. Conclusion: This study revealed that consumer purchasing preferences might vary between countries regarding marbling and perception of quality. Furthermore, higher degrees of doneness could be the preference of these consumers. Thus, further studies are needed to increase consumer satisfaction in these countries.

본 연구는 인터넷 자원자 패널에 의한 사회조사 사례를 보고하면서 조사 자원자의 사회심리적 특성을 규명하고 패널표본의 편향성을 제거하기 위한 성향조정 가중법(propensity adjustment weighting)의 효용에 대한 정량적 평가 결과를 제시한다. 광역시 도, 지역크기(동 읍면), 성별, 연령대, 교육정도, 소비생활 만족도, 소득분배 견해, 일반신문 보기, 인터넷신문 보기 등 9개 요인을 조정 기준변수로 사용하여, 2009년 통계청 온라인 사회조사 자료(응답자 수 2,903명)를 같은 해에 지역추출 면대면(face-to-face, FTF)으로 실시된 통계청 사회조사 자료(응답자 수 37,049명)에 맞도록 성향조정 가중치를 적용하였다. 그 결과 106개 평가 문항 가운데 80% 정도의 문항에서 광역시 도, 동 읍면, 성별, 연령대 등 기본 인구지리적 변수에 의한 기본가중치 보정에 비하여 향상된 추정치를 제공하는 것으로 평가되었다. 이는 성향조정에 일부 한계가 있기는 하지만 자원자 패널에 의한 인터넷 조사를 향후 사회조사에서 활용해 볼 가치가 있음을 의미한다. 본 연구에서 준거조사(reference survey)로 쓰인 2009년 통계청 면대면 사회조사는 표본크기가 크고 일반적인 사회심리적 태도 문항과 인터넷 관련 행태 문항을 포함하므로 각종 인터넷 조사에서 준거자료로서의 활용가치가 충분히 있다.

The purpose of this study is to survey the transition of the type of openings in korean traditional archiectures. To do this, various types of openings at the backside of Daechung of 23 Hyang-Gyo Myung-Ryun-Dangs were investigated. After the classification in some groups according to their types and their periods of constuction, the tasnsition of the type of openings was analysed. Results are as follows. (1) The openings constructed form 16th to 17th century, the earliest form, is a ledged and battened panel window(or framed and ledged panel window) whose mullion is built on the frame of window. It is presumed that these types were widely used before 17th century. (2) The next type is ledged and battened panel window(door) (or framed and ledged panel window) which lacks a mullion. These types were thought to be customed after 18th century. (3) The lastest type, which is appeared from 19th to 20th century, is an characteristic backside opening(ledged and battened panel window or framed and ledged panel window) that among 3 column spacings the central one is enlarged in comparison with the right and left ones. Through this transition pattern of the openings, can be menifested that the trend of 20th century is to enlarge convenience of usage by constuctiong door and eliminating some windows.
