This paper tried to find various ideas for the purpose of increasing the demand for domestic bean which is the main raw material of bean curd products. To accomplish this objective, purchasing behavior of the current consumers were surveyed and the consumer evaluation of the products were investigated. Using experiment conjoint analysis, consumers' marginal willingness to pay for several important attributes of the products were derived. Among the attributes analyzed, the origin of the material bean turned out to be the most important attributes of all.

This study probed into some characteristics of the urban household such as household income, number of the household, age distribution of the family members, their characteristics of shopping behavior such as the shopping place, types of the packaging and the characteristics of the time series, using consumer panel data of the Rural Development Administration (RDA). It further examined how the above factors affect fruit purchasing prices and then estimates the degree of the influence by each factor. The study looked at the purchase of apples, pears, tangerines, and oranges - the most favorite fruits in Korea. The results of this study can be utilized as the basic information for marketing strategies and/or for the establishment of future policy plans related to fruits consumption.

To help improve the current government practice of direct damage-compensation policies, resulting from the loss of profit, sustained by Hanwoo farmers, as a result of the recent Korea-U. S. Free Trade Agreement (FTA), this research aims to examine any problems or issues caused by said policies. To accomplish this task, we have established Hanwoo-SIMO model and estimated the damage of Hanwoo farmers, one without the implementation of the FTA and another with the FTA, to compare and contrast the two. We then analyzed the efficacy of the current government policies. According to our analysis, the current direct compensation policies for the loss of profit on the part of Hanwoo farmers are insufficient. To address this problem, we recommend the government enact a new direct damagecompensation law to address the following issues. First, as the base formula of damage-compensation, the government should use current price of the beef rather than the annually changing flexible price. Second, the flexible control index should remain fixed at 1.0 rate while the government prepares the adequate amount of the damage compensating direct payment resulting from the FTA. Third, the direct government compensation policy should extend beyond the current 15 years (2013-2026) as the profit loss is expected to increase after the midpoint of the FTA.

본 연구의 목적은 우리나라 김 산지 수출량 결정 모형을 개발하는데 있다. 모형의 설명변수에는 국내시장의 연도별, 월별 생산물량과 산지가격, 그리고 수출가격과 환율이 포함되었다. 추정 결과 김 수출은 단기적인 생산량의 증가 보다 장기 적인 생산량의 증가에 더 큰 영향을 받는 것으로 나타났다. 또한 환율이나 수출가격이 상승할 경우 수출량이 탄력적으로 반응하였다. 반면에 산지가격이 상승할 경우 김 수출은 감소하나, 비탄력적인 모습을 보였다. 따라서 김의 수출을 증가시키 기 위해서는 중장기적인 생산량 증대를 위한 기반시설 확립, 수출가격이나 환율변동에 대한 보다 정확한 예측 및 관련 정보 제공이 중요하다고 판단된다. The objective of this study was to develop an export determinant model for laver in the producing district. The annual and monthly amounts of laver products, local price, export price, and foreign exchange rate were included as explanatory variables. The estimation showed that the laver export is influenced more by the long term rather than short term product increase. In addition, as the foreign exchange rate and export price increase, the quantities exported decrease elastically. On the other hand, as the price in the local market increases, the quantities exported decrease non-elastically. Therefore, to enhance the laver exports, it is important to establish infrastructure for long term production increase, forecast and provide information on the export price and foreign exchange rate more accurately.

목적: 원시 환자에서 라섹의 단기 임상성적을 보고하고, 이 중 조절 내사시를 가진 환자의 라섹 임상성적을 포함해 분석하고자 하였다. 대상과 방법: 2005년 5월부터 2013년 3월까지 서울대학교병원 안과에서 원시를 진단 받고 라섹 수술을 받은 환자 중 최소 1개월 이상 경과 관찰된 10명 18안을 대상으로 의무기록을 후향적으로 분석하였다. 수술 후 1개월 및 3개월째 나안시력 및 구면렌즈대응치를 측정하였으며, 고위수차 및 대비감도는 술 후 3개월째에 측정하였다. 술 전의 안경교정 후 정위의 원거리 사시각 및 근거리 사시각과의 차이를 분석하였다. 결과: 환자들의 평균 연령은 32 ± 11세, 술 전 구면렌즈대응치는 평균 2.95 ± 1.24디옵터(D)였다. 나안시력의 logMAR는 수술 1, 3개월 후 각각 +0.17 ± 0.15, +0.14 ± 0.15로 수술 전과 통계적으로 유의한 차이가 없었다. 구면렌즈대응치는 수술 1, 3개월 후 각각 -0.22 ± 1.22D, 0.38 ± 0.91D로 원시가 효과적으로 교정되었다. 수술 전 내사시가 있던 환자 6명에서 수술 전 교정 후 사시각은 7.83 ±3.60 prism diopter (PD)로 수술 후 나안 시력으로 측정한 사시각인 4.67 ± 5.65 PD와 통계적으로 차이를 보이지 않았다. 합병증으로는 3안(16.7%)에서 지연 창상회복을 보였으며, 이 중 한 안(5.56%)에서 경도 이상의 각막 혼탁이 지속되었으나 시력저하는 없었다. 결론: 라섹도 기존에 보고된 라식에 상응하는 원시 및 사시 교정 효과를 보이나 창상지연에 주의하여야 한다. Purpose: To evaluate short-term clinical outcomes following hyperopic laser-assisted subepithelial keratomileusis (LASEK) in Korean patients. Methods: This retrospective study included 18 eyes of 10 patients who underwent hyperopic LASEK between May 2005 and March 2013 in Seoul National University Hospital. Visual acuity and spherical equivalent were evaluated preoperatively and at 1 and 3 months postoperatively. High order aberrations and contrast sensitivity were measured before and 3 months after the operation. Alternative prism cover test (APCT) was performed both preoperatively with correction and postoperatively without correction. Results: The mean age of patients was 32 ± 11 years and the mean spherical equivalent refractive error was -2.95 ± 1.24 diopters (D). Uncorrected visual acuities were log MAR +0.17 ± 0.15 and log MAR +0.14 ± 0.15 at postoperative 1 month and 3 months, respectively and showed no significant difference in best corrected visual acuity (+0.25 ± 0.30). Spherical equivalent was -0.22 ± 1.22 D at 1 month and 0.38 ± 0.91 D at 3 months postoperatively. In 6 patients who had esotropia before the operation, APCT was 7.83 ± 3.60 prism diopters (PD) esotropia at distance with correction preoperatively and 4.67 ± 5.65 PD at distance without correction postoperatively. Three patients (16.7%) showed delayed wound healing with 1 (5.56 %) having persistent corneal opacity without significant visual loss. Conclusions: The effect of LASEK may be comparable for correcting hyperopia and esotropia when compared with the effect of LASIK in previous reports; however, delayed wound healing may be a concern.

This study aims to examine the comsumer preference for packaged bean curd that takes a growing public interest. Specifically, this study tried to examine which is more important - the place of origin of the raw bean or the environmental-friendliness of the raw bean. Surveys were conducted to obtain information, such as the consumer evaluation for food safety on imported food products from China and the consumer perception of Chinese organic food products, Using the binary probit model, the relationship between consumer’s choice of packaged bean curd and potentially important factors that can affect the consumer’s choice was analyzed. A summary of this research and some policy implications follow. The results of this study can be used as the basic guideline as to how to extend the safety of imported food products, in general, and how to further develop the packaged bean curd industry in Korea, in particular.
