Providing information about food and nutrition through labels can help consumers reduce the cost of acquiring information and reduce the likelihood of making poor choices. However, the utility of food labels has not been fully realized due to the complicated method of providing information and the lack of awareness of consumers. In previous studies, consumer label utilization rates and economic value measures for labels have been shown to be very different. This is due to the fact that they have generally relied on hypothetical questionnaires. The purpose of this study is to suggest a method that can achieve similar results to actual purchasing activity, although Internet-based questionnaires are used. In addition, we measured consumers' willingness to pay for labels and verified that the location of the labels gave rise to differences in consumer perceptions and the values of the label. The factors affecting consumers’ utilization of the labels were also estimated, and the results showed that age and gender have significant effects on the use of food labels.

본 연구에서는 강원도 인제지역의 가래나무의 수액 출수와 영향인자들을 분석하여 고로쇠나무 수액의 대체자원으로서 최적의 수액 출수 조건을 얻고자 출수량, 흉고직경, 시험지의 기온과 상대습도를 2008년 2월 1일∼3월 31일의 기간에 측정하여 출수량과 다른 측정값들과의 상관성 분석을 수행하였고 고로쇠나무의 경우와 비교 분석하였다. 가래나무 수액의 출수는 고로쇠나무 경우와 유사한 출수 시기와 출수 기간을 가지고 있었으나 가래나무 수액출수는 출수 기간의 초기에 집중되었다. 동일 지역의 고로쇠나무 수액의 출수량은 나무의 흉고직경이 증가할수록 증가한 것과 달리 가래나무 수액의 출수량은 흉고직경 증가에 따른 뚜렷한 증감을 관찰할 수 없었다. 수액출수량이 높은 개체의 경우 고로쇠나무와 가래나무 모두 단위 흉고직경 당 출수량은 높은 것으로 나타났으며, 고로쇠나무의 흉고직경 당 출수량은 전체 평균 0.9 ± 0.1 ℓ/cm으로 가래나무의 평균 0.3 ± 0.1 ℓ/cm에 대비하여 3배에 달하였다. 수액이 많이 출수되는 날의 기온와 상대습도는 고로쇠나무와 가래나무 경우 모두 서로 유사하게 나타나 가래나무 수액 출수는 고로쇠나무의 경우와 같이 외부 기후 조건에 많이 영향받는 것으로 판단되었다. 수액출수량과 기온 및 대기 습도와의 상관 분석에서 가래나무의 경우 일중 최저 기온(P < 0.05)이, 고로쇠나무의 경우 기온차(P < 0.01)가 수액 출수량에 가장 유의적으로 영향을 미치는 것으로 나타났다. 이러한 결과를 볼 때 가래나무의 수액 출수는 고로쇠나무와 유사한 기후 조건에서 발생하나 그 수액 출수량은고로쇠나무보다 적고 이에 영향하는 주요 인자 또한 다른 것으로 생각된다. This study was carried out to investigate the optimum conditioan for sap exudation of Juglans mandsburica in comparison with Acer mono Max. tree in a site of Inje-Gun, Gangwon-Do, Korea. Amount of sap exudation, air temperature, relative air humidity and tree diameter at breast height (DBH) were monitored for the priod of February 1 through March 31, 2008, and correlation analysis of several factors affecting on sap exudation was carried out. Sap exudation from J. mandsburica initiated on Feb. 28 as the same time in case of A.mono and continued for a month, and enhanced in early March compared to around the middle of March for A.mono. The amount of sap of A.mono was linearly proportional to the diameter at breast height (DBH) but there was no apparent relationship for J. mandsburica. As the amount of sap exudation per tree increased then sap exudation per unit DBH was also linearly proportional in both J. mandsburica and A.mono. The amount of sap exudation per unit DBH of J. mandsburica were 0.3±0.1ℓ/cm on average, which was one third times of 0.9±0.1ℓ/cm for A.mono. During the days of enhanced sap exudation, the atmospheric conditions such as air temperature and relative humidity around J. mandsburica trees were very similar with those of A.mono. The minimum tempereature was a significant factor affecting the amount of sap J. mandsburica whereas the range of temperature was the principal factor A.mono. In conclusion, the sap of J. mandsburica exudated in atmospheric conditions similar to A.mono, but the amount of sap was affected by different atmospheric factors compared to A.mono.

As rural areas have been changing rapidly due to international trade liberalization, the importance of nonfarm income has been increasingly recognized for the sustainability of rural economy in Korea. In this context, the government has developed a rural tourism business in order to increase nonfarm income and consequently the demand for the rural tourism has been increased. However, inevitable incidents continue to occur in the tourist sites. Whenever these dangerous disasters happen, the tourists are aware of the potential risks and tend to avoid or cancel their plans to visit rural areas. In tourism sector, the perceived risk has been regarded as the important variable which can have an influence on individual’s preference or intention of revisiting. In this regard, it is necessary to examine the impact of the risk perception associated with disasters that occur persistently and inevitably in the rural tourism. Therefore, this study analyzes the impact of tourists’ risk perception on rural tourism using the survey data obtained from the potential rural tourists. Based on empirical findings, this study proposes a strategy and policy associated with a risk management, which can be useful for the revitalization of rural tourism.

최원실(Won-Sil Choi),이상현(Sang-Hyeon Lee) 한국농업경제학회 2020 農業經濟硏究 Vol.61 No.1

The purpose of this study is to analyze the effect of tourist site attractiveness on the selecting tourist destinations, tourism visits and the travel expenditure. The tourist attractiveness is classified into natural environment characteristics and artificial characteristics. Natural environment characteristics imply that whether the region has beaches and national park and artificial characteristics imply that whether the region has regional festivals and resort-related infrastructure. By using a conditional logit model, we analyze the effect of tourist site attractiveness on tourists choice of tourist destinations. The effect of tourist site attractiveness on tourism visits and the travel expenditure is estimated by generalized least squares. According to the estimation result, tourists are more likely to select regions with beaches or national parks and regions with many festivals and resort-related infrastructure. Tourism visits is high in regions with beaches and many festivals. It is estimated that travel expenditure is high in regions with beaches or in national parks.

본 연구는 경상남도 함양군 지리산의 고로쇠나무 수액의 출수와 영향 인자들을 분석하여 최적의 출수 조건을 얻는데 기여하고자, 출수량과 시험지의 기온 및 상대습도, 흉고직경 그리고 수액내 당 함량 사이의 상관성을 분석하였다. 고로쇠나무의 흉고직경에 비례하는 출수량과의 상관성은 출수량이 많은 날에 높았고 출수 일수와 시기는 공시목 사이에 큰 차이점이 없었다. 출수량이 높았던 날들의 기온은 일평균기온 1.2±1.6℃, 일최저기온 -4.3±1.5℃ 그리고 일최고기온 11.8±1.9℃로 나타났다. 수액 출수는 기온이 영하의 온도를 지속하거나 영상의 온도를 지속할 경우에는 관찰되지 아니하였다. 기온과 출수량과의 상관 분석에서 일최고기온과 일평균기온이 유의적(p<0.05)으로 관련성이 있는 것으로 나타났다. 수액의 출수 기간 동안 자당의 농도는 일정 수준을 유지하였으나 출수가 종료되는 시점에서 급격하게 감소하였다. This study was carried out to investigate the optimum condition for sap exudation of Acer mono Max. tree in a site of Mt. Jiri, Hamyang-gun, Korea. Amount of sap exudation, air temperature, relative air humidity, tree diameter at breast height (DBH) and sugar content in sap were monitored during the early springtime, and correlation analysis of several factors was carried out to explain tree-to-tree and date-to-date variations in sap exudation. The correlation, linearly-associated between DBH and sap amount, was strengthened as daily amount of sap increased, but there was no significant tree-to-tree variation in time and period for sap exudation. When amount of sap exudation was above 10 liter/day, the mean air-temperature was averaged at 1.2±1.6℃, the minimum at -4.3±1.5℃ and the maximum at 11.8±1.9℃. The maximum air temperature and mean air temperature were significant (p<0.05) factors for amount of sap in correlation analysis to explain date-to-date variation in sap exudation. Sucrose content in sap was in the range of 1.5 and 1.7% during exudation days, but sharply reduced to 0.6% level at the end of exudation period.

본 연구는 목질계 섬유판 제조에 있어 목섬유에 대한 도계부산물인 닭털의 부분적 대체화 가능성을 검토하기 위하여 수행하였다. 닭털은 주로 케라틴계 단백질로 구성되어 있으며, 외형적으로 목섬유와 큰 차이는 없었다. 닭털의 전처리 방법에 따른 포름알데히드 흡착능을 비교한 결과, 닭털을 고온/고압에서 처리하고 분쇄한 우모분에서 가장 높았다. 한편 일반 가위로 절단한 닭털과 이를 가정용 믹서로 고해시킨 닭털의 폼알데히드 흡착량을 dinitrophenylhydrazine법으로 측정한 결과 차이는 없었다. 닭털, 고해 닭털, 우모분을 각각 목섬유의 전건무게를 기준으로 5 wt%로 혼합하여 제조한 중밀도섬유판(MDF)의 물성과 폼알데히드방출량은 닭털의 전처리 조건에 영향을 받지 않았다. 그러나 이 측정치를 목섬유만으로 제조한 MDF와 비교하였을 때, 두께팽윤율과 폼알데히드방출량은 크게 개선되었다. 따라서 현재 생산 현장에서 적용되고 있는 요소수지를 이용한 MDF 제조에 있어 목섬유와 함께 일정한 양의 닭털, 고해 닭털 또는 우모분을 첨가할 경우 치수안전성과 폼알데히드방출량이 개선된 MDF의 제조가 가능할 것으로 예상된다. 그러나 MDF제조에 있어 닭털의 사용은 현재 상황에서 목섬유와 비교하여 원료 확보의 어려움과 높은 단가로 경제성이 낮은 것으로 조사되었다. 경제성 향상을 위하여 중소형 도계장에서 발생하는 닭털을 이용하거나, 동물성 사료의 금지에 대한 대비책 및 인플루엔자 감염 조류에 대한 환경적 처리 방안으로 닭털의 섬유판 원료에 대한 부분적 대체화 기술은 향후 사용 가능성이 충분할 것으로 판단된다. This study was conducted to investigate the potential of chicken feather (CF), which is a by-product in poultry industry, as a partial substitute of wood fiber in the production of wood-based fiberboard. Keratin-type protein constituted the majority of CF, and its appearance did not differ from that of wood fiber. When the formaldehyde (HCHO) adsorptivities of CF compared by its pretreatment type, feather meal (FM), which was pretreated CF with high temperature and pressure and then grounded, showed the highest HCHO adsorptivity. In addition, there was no difference between the adsorbed HCHO amounts, which was measured by dinitrophenylhydrazine method, of scissors-chopped CF and CF beated with an electrical blender. Mechanical properties and HCHO emission of medium-density fiberboards (MDF), which were fabricated with wood fiber and 5 wt% CF, beated CF or FM based on the oven-dried weight of wood fiber, were not influenced by the pretreatment type of CF. However, when the values compared with those of MDF made with just wood fiber, thickness swelling and HCHO emission of the MDF were improved greatly with the addition of CF, beated CF or FM. Based on the results, it might be possible to produce MDF with improved dimensional stability and low HCHO emission if CF, beated CF or FM is added partially as a substitute of wood fiber in the manufacturing process of MDF produced with the conventional urea-formaldehyde resin of $E_1$ grade. However, the use of CF or FM in the production of MDF has a low economic feasibility at the current situation due to the securing difficulty and high cost of CF. In order to enhance the economic feasibility, it requires to use CF produced at small to medium-sized chicken meat plants. More importantly, it is considered that the technology developed from this research has a great potential to make provision for the prohibition of animal-based feed and to dispose environmentally avian influenza-infected poultry.
