  • Although the production of chestnut in Korea is the second largest in the world, domestic consumption of chestnut is very limited. Furthermore, consumption of chestnut in Korea is highly dependent on export to Japan and China. Large amount of chestnut in Korea have been deteriorated and discarded during storage. In order to increase the consumption of chestnut in Korea, it is necessary to know the processing properties of chestnut and its starch. Additionally, through the various investigations such as modification treatment, it will be extended to utilization of chestnut. So far, there is a little information on the processing properties of chestnut; therefore, the expansion of research will bring results to increase the consumption of chestnut.

  • This study was carried out to estimate price and domestic consumption functions of chestnut using time series data for the period 1970~1989. Using a regression analysis method, price and domestic consumption functions of chestnut in Korea are estimated. The result of this study reveals that the optimum function of price for chestnut is PR= -249.33965 + 163532.56817 EX/POP-4.10177 PD+4.02877 DC+6056.98339 GDP/POP($R^2$=0.88207), and that optimum function of domestic consumption for chestnut is ln DC=14.97145+1.48279 ln PD/POP - 0.32853 ln GDP - 0.02337 ln PR - 0.12117 ln EX($R^2$=0.98689). On the ground that instability of prices make the income of producer and family finances of consumer unstable, the object of price-policy should be to stabilize price of chestnut in Korea.

  • In Korea, chestnut production is increasing each year, but consumption is far below production. We investigated the effect of chestnut extracts on antioxidant activity and anticancer effects. Ethanol extracts of raw chestnut (RCE) or chestnut powder (CPE) had dose-dependent superoxide scavenging activity. Viable numbers of MDA-MD-231 human breast cancer cells, DU145 human prostate cancer cells, and AGS human gastric cancer cells decreased by 18, 31, and 69%, respectively, following treatment with $200{\mu}g/mL$ CPE for 24 hr. CPE at various concentrations ($0-200{\mu}g/mL$) markedly decreased AGS cell viability and increased apoptotic cell death dose and time dependently. CPE increased the levels of cleaved caspase-8, -7, -3, and poly (ADP-ribose) polymerase in a dose-dependent manner but not cleaved caspase-9. CPR exerted no effects on Bcl-2 and Bax levels. The level of X-linked inhibitor of apoptosis protein decreased within a narrow range following CPE treatment. The levels of Trail, DR4, and Fas-L increased dose-dependently in CPE-treated AGS cells. These results show that CPE decreases growth and induces apoptosis in AGS gastric cancer cells and that activation of the death receptor pathway contributes to CPE-induced apoptosis in AGS cells. In conclusion, CPE had more of an effect on gastric cancer cells than breast or prostate cancer cells, suggesting that chestnuts would have a positive effect against gastric cancer.

  • 본 연구는 임산물 가운데 생산과 수출 양면에서 가장 중요한 위치를 차지하고 있는 밤을 대상으로 친환경 밤에 대한 소비자 구입의향 및 행태를 통계학적으로 종합 분석하여 친환경 밤의 소비확대를 도모할 수 있는 방안을 제시하고자 하였다. 이를 위해 우리나라 소비중심지인 서울(350명)과 수도권의 신도시 일산(150명), 분당(150명) 등 총 650명의 가정주부를 대상으로 설문조사를 실시하였다. 그 결과, 친환경 밤에 대한 소비촉진 활동은 모든 소비자를 대상으로 하기보다는 일차적으로 대도시에 거주하고 있는 3~4인 가족, 연령층은 30~40대의 젊은 주부계층, 교육 수준은 대졸학력 이상, 윌평균 수입액은 450만원 이상 고소득, 친환경임산물을 구입한 경험이 있는 소비자 등을 특정 표적대상으로 하여 소비확대 방안을 마련하는 것이 효과적이라 할 수 있다. 이를 위해서는 친환경임산물 판매처의 안정적인 확보와 함께 소비자가 인식하고 있는 친환경 밤에 대한 가치와 품질이 가격에 반영되는 가격설정이 필요하다. 이는 본 연구에서 실시한 소비자들의 종합적이며 결집된 지표인 친환경 밤에 대한 지불의사금액을 기초로 가능할 수 있을 것으로 판단된다.

  • 최근 천연의 의약품과 식품에 대한 관심이 높아지면서 약리성분이 우수하여 수요가 증가하고 있는 겨우살이 [Viscum album var. coloratum(Kom.) Ohwi] 와 겨우살이의 기주식물인 상수리나무(Quercus acutissima Carr.)가지의 조직특성을 조사하고 인공재배 기초 자료로 활용하기 위하여 수행한 결과는 다음과 같다. 겨우살이 종자가 기주목에 부착되면 종자로부터 성장한 흡기가 수피를 뚫고 들어가 형성층 부위에서 왕성한 세포분열을 통하여 여러 갈래로 분지를 형성하며, endophyte가 수피 속에서 성장하다가 일정한 시기가 되면 수피 외부조직으로 발달하여 줄기와 잎으로 성장하였다. 겨우살이 기주목인 상수리나무의 가지는 심재화가 진행되지 않았지만 타일로시스가 부분적으로 발달한 것은 겨우살이 endophyte의 침투영향으로 생각된다. 겨우살이 줄기의 구성세포는 도관상 가도관, 후벽세포, 방사유세포, 축방향유세포로 구성되어 있으며 활엽수로 분류되지만 도관이 분포하지 않았고 도관의 역할을하는 도관상 가도관이 있는 것으로부터 기주목 도관의 벽공과 겨우살이 가도관의 천공부가 결합하는 것으로 생각된다. 겨우살이 줄기의 구성세포 분포비율은 수령이 증가함에 따라 후벽세포의 분포비율이 높았다. 겨우살이 조직은 일반 목본식물에 비하여 유세포의 분포비율이 높고 세포내에 많은 내용물을 포함하고 있었다.

  • 최근 단기소득임산물 생산량 증가에 따라 정부나 관련 기관에서 단기소득임산물에 대한 소비를 촉진하기 위한 다양한 노력을 하고 있다. 소비 촉진 노력의 일환으로 단기소득임산물에 대한 소비자 의향 연구가 진행되고 있지만 대부분의 연구는 설문조사에만 의존하는 상황이다. 정보화 시대에서 소비재에 대한 소비자 의향은 인터넷 확산에 따라 SNS에 크게 반영되고 있다. 기존 연구에서 설문에만 의존하는 것을 탈피하여 소비자의 의향이 직접 반영되어 있는 SNS를 직접 분석하는 것이 필요하다. 이에 본 연구는 소셜 빅테이터 분석을 통해 주요 단기소득임산물에 대한 소비자 의향을 파악하였으며, 이 결과를 이용해 해당 단기소득임산물의 판매 촉진 전략을 수립하였다. 본 논문은 설문조사만을 이용한 기존의 단기임산물 관련 연구들과는 다르게 적은 비용으로 많은 표본들의 즉각적인 반응을 파악할 수 있는 SNS 빅데이터를 활용하여 소비자 의향을 파악하였다는 것에 차별성이 있다. 본 연구의 결과는 정부나 관련 기관의 단기소득임산물의 소비 촉진 정책에 직접적으로 도움이 되고 궁극적으로는 임가 소득 향상과 건강한 산림관리에 도움이 될 수 있을 것이라 기대된다.

  • 최근 멧돼지의 개체수 및 농작물 피해 증가로 인하여 사회적 문제를 야기 시키고 있다. 국내 멧돼지에 대한 연구는 미미하여 향후 효과적인 멧돼지 관리를 위해서는 종에 대한 생태적 연구가 필요하다. 본 연구는 2012년 5월부터 12월까지 경남 거창군 일대에서 유해야생동물 포획을 통해 수집된 멧돼지 위 내용물(n=79) 분석을 통하여 식이습성 구명 및 선호 농작물을 파학하기 위해 수행되었다. 연구 결과 멧돼지는 주로 식물성 먹이를 섭식하며, 계절별로 유의한 차이를 나타냈다. 식물성 먹이는 잎-줄기가 83.5%로 가장 높은 출현율 보였으며, 농작물을 포함한 식물성 먹이는 건중량의 93.5%을 차지하였다. 무척추동물의 발견 빈도는 높았으나 빠르게 소화되는 특성으로 인하여 건중량은 낮게 나타났다. 식이농작물로는 밤, 벼, 사과 등이 선호하는 농작물로 나타났다. 수확기 농작물은 멧돼지가 야생 먹이보다 선호하여 의도적으로 섭식하는 것으로 판단된다. 지렁이는 총 수집된 위에서 50%의 출현율을 보였으며, 섭식 마릿수는 여름에 가장 높고, 겨울에 낮은 것으로 나타났다. 멧돼지는 전형적인 잡식성의 성향을 보이며, 시기에 따라 섭식하는 식이물이 다른 것으로 나타났다. 향후 멧돼지에 의한 농작물 피해를 줄이기 위해서는 밤나무림에 인접한 논과 사과 과수원의 우선적인 피해방지가 필요할 것으로 판단된다.

  • 본 연구는 UR농산물협상에서 우리 나라가 약속한 시장개방(市場開放)에 대한 이행실적(履行實績)을 평가하고 UR에 의한 시장개방이 국내 주요 단기소득임산물 시장에 미친 영향(影響)을 분석하였다. WTO농업협정의 이행실적 등은 관련자료 및 통계치를 이용하여 분석하였고, UR이후 수입개방이 밤, 대추, 잣, 호도, 표고시장에 미친 영향은 선행연구의 수요(需要) 및 공급탄성치(供給彈性値)와 UR이후의 수입량, 생산량 소비량 등의 자료를 이용하여 추정(推定)하였다. 1995년부터 1999년까지 5년동안 관세할당제도(關稅割當制度)에 의한 밤, 잣, 대추의 수입물량은 우리나라가 약속한 최소시장접근(最小市場接近) 물량(物量)을 초과하지 않았다. 현재 단기소득임산물의 실행관세율(實行關稅率)도 양허관세율(讓許關稅率)에 비해 상당히 낮으며 이러한 관계는 2004년까지 유지될 것이다. UR이후 단기소득임산물의 수입증가로 잠재적(潛在的) 국내가격(國內價格)이 하락되었고 이에 따라 소비지출액(消費支出額)이 감소되고 소비자잉여(消費者剩餘)가 증가된 것으로 추정되었다. 그러나 단기소득임산물의 수업증가로 인해 생산량이 큰 폭 감소된 것으로 추정되었으며 생산에 미친 부정적(否定的)연 효과(效果)가 소비에 미친 긍정적(肯定的)인 효과(效果)를 상회(上廻)한 것으로 추정되었다. 단기소득임산물은 UR의 결과 낮은 관세율로 수출시장에 접근할 수 있었음에도 불구하고 대부분의 수출(輸出)이 감소(減少)되었다.

  • The interplay between hedonic and utilitarian attributes has assumed special significance in recent years; it has been proposed that consumption offerings should be viewed as experiences that stimulate both cognitions and feelings rather than as mere products or services. This research builds on previous work on hedonic versus utilitarian benefits, regulatory focus theory, customer satisfaction to address two question: (1) Is the shopping goal at the point of purchase different from the shopping value? and (2) Is the customer loyalty after the use different from the shopping value and shopping goal? We surveyed 345 peoples those who have bought the electronic-goods within 6 months. This research dealt with the shopping value which is consisted of 2 types, hedonic and utilitarian. Those who pursue the hedonic shopping value may prefer the pleasure of purchasing experience to the product itself. They tend to prefer atmosphere, arousal of the shopping experience. Consistent with previous research, we use the term "hedonic" to refer to their aesthetic, experiential and enjoyment-related value. On the contrary, Those who pursue the utilitarian shopping value may prefer the reasonable buying. It may be more functional. Consistent with previous research, we use the term "utilitarian" to refer to the functional, instrumental, and practical value of consumption offerings. Holbrook(1999) notes that consumer value is an experience that results from the consumption of such benefits. In the context of cell phones for example, the phone's battery life and sound volume are utilitarian benefits, whereas aesthetic appeal from its shape and color are hedonic benefits. Likewise, in the case of a car, fuel economics and safety are utilitarian benefits whereas the sunroof and the luxurious interior are hedonic benefits. The shopping goals are consisted of the promotion focus goal and the prevention focus goal, based on the self-regulatory focus theory. The promotion focus is characterized into focusing ideal self because they are oriented to wishes and vision. The promotion focused individuals are tend to be more risk taking. They are more sensitive to hope and achievement. On the contrary, the prevention focused individuals are characterized into focusing the responsibilities because they are oriented to safety. The prevention focused individuals are tend to be more risk avoiding. We wanted to test the relation among the shopping value, shopping goal and customer loyalty. Customers show the positive or negative feelings comparing with the expectation level which customers have at the point of the purchase. If the result were bigger than the expectation, customers may feel positive feeling such as delight or satisfaction and they would want to share their feelings with other people. And they want to buy those products again in the future time. There is converging evidence that the types of goals consumers expect to be fulfilled by the utilitarian dimension of a product are different from those they seek from the hedonic dimension (Chernev 2004). Specifically, whereas consumers expect the fulfillment of product prevention goals on the utilitarian dimension, they expect the fulfillment of promotion goals on the hedonic dimension (Chernev 2004; Chitturi, Raghunathan, and Majahan 2007; Higgins 1997, 2001) According to the regulatory focus theory, prevention goals are those that ought to be met. Fulfillment of prevention goals in the context of product consumption eliminates or significantly reduces the probability of a painful experience, thus making consumers experience emotions that result from fulfillment of prevention goals such as confidence and securities. On the contrary, fulfillment of promotion goals are those that a person aspires to meet, such as "looking cool" or "being sophisticated." Fulfillment of promotion goals in the context of product consumption significantly increases the probability of a pleasurable experience, thus enabling consumers to experience emotions that result from the fulfillment of promotion goals. The proposed conceptual framework captures that the relationships among hedonic versus utilitarian shopping values and promotion versus prevention shopping goals respectively. An analysis of the consequence of the fulfillment and frustration of utilitarian and hedonic value is theoretically worthwhile. It is also substantively relevant because it helps predict post-consumption behavior such as the promotion versus prevention shopping goals orientation. Because our primary goal is to understand how the post consumption feelings influence the variable customer loyalty: word of mouth (Jacoby and Chestnut 1978). This research result is that the utilitarian shopping value gives the positive influence to both of the promotion and prevention goal. However the influence to the prevention goal is stronger. On the contrary, hedonic shopping value gives influence to the promotion focus goal only. Additionally, both of the promotion and prevention goal show the positive relation with customer loyalty. However, the positive relation with promotion goal and customer loyalty is much stronger. The promotion focus goal gives the influence to the customer loyalty. On the contrary, the prevention focus goal relates at the low level of relation with customer loyalty than that of the promotion goal. It could be explained that it is apt to get framed the compliment of people into 'gain-non gain' situation. As the result, for those who have the promotion focus are motivated to deliver their own feeling to other people eagerly. Conversely the prevention focused individual are more sensitive to the 'loss-non loss' situation. The research result is consistent with pre-existent researches. There is a conceptual parallel between necessities-needs-utilitarian benefits and luxuries-wants-hedonic benefits (Chernev 2004; Chitturi, Raghunathan and Majaha 2007; Higginns 1997; Kivetz and Simonson 2002b). In addition, Maslow's hierarchy of needs and the precedence principle contends luxuries-wants-hedonic benefits higher than necessities-needs-utilitarian benefits. Chitturi, Raghunathan and Majaha (2007) show that consumers are focused more on the utilitarian benefits than on the hedonic benefits of a product until their minimum expectation of fulfilling prevention goals are met. Furthermore, a utilitarian benefit is a promise of a certain level of functionality by the manufacturer or the retailer. When the promise is not fulfilled, customers blame the retailer and/or the manufacturer. When negative feelings are attributable to an entity, customers feel angry. However in the case of hedonic benefit, the customer, not the manufacturer, determines at the time of purchase whether the product is stylish and attractive. Under such circumstances, customers are more likely to blame themselves than the manufacturer if their friends do not find the product stylish and attractive. Therefore, not meeting minimum utilitarian expectations of functionality generates a much more intense negative feelings, such as anger than a less intense feeling such as disappointment or dissatisfactions. The additional multi group analysis of this research shows the same result. Those who are unsatisfactory customers who have the prevention focused goal shows higher relation with WOM, comparing with satisfactory customers. The research findings in this article could have significant implication for the personal selling fields to increase the effectiveness and the efficiency of the sales such that they can develop the sales presentation strategy for the customers. For those who are the hedonic customers may be apt to show more interest to the promotion goal. Therefore it may work to strengthen the design, style or new technology of the products to the hedonic customers. On the contrary for the utilitarian customers, it may work to strengthen the price competitiveness. On the basis of the result from our studies, we demonstrated a correspondence among hedonic versus utilitarian and promotion versus prevention goal, WOM. Similarly, we also found evidence of the moderator effects of satisfaction after use, between the prevention goal and WOM. Even though the prevention goal has the low level of relation to WOM, those who are not satisfied show higher relation to WOM. The relation between the prevention goal and WOM is significantly different according to the satisfaction versus unsatisfaction. In addition, improving the promotion emotions of cheerfulness and excitement and the prevention emotion of confidence and security will further improve customer loyalty. A related potential further research could be to examine whether hedonic versus utilitarian, promotion versus prevention goals improve customer loyalty for services as well. Under the budget and time constraints, designers and managers are often compelling to choose among various attributes. If there is no budget or time constraints, perhaps the best solution is to maximize both hedonic and utilitarian dimension of benefits. However, they have to make trad-off process between various attributes. For the designers and managers have to keep in mind that without hedonic benefit satisfaction of the product it may hard to lead the customers to the customer loyalty.
