Most farmers who participated in model project on traceability in Korea understand the necessities on traceability introduction eventhough if increases production costs. In this model project, the problems that were point outed by participating farmers were as follows Marketing of products, advertisement & training program, setting of guidelines on traceability system for each items. In this research, survey regarding to organic agricultural products purchase?will by time was carried out and ratio of real purchase and its purchase time among people who showed their purchase?will was investigated. The reason of this procedure is to estimate "final purchase rate". This result was applied to logistic model and bass model than finally obtained organic agricultural product's purchase demand.

The Importance of agricultural products sales in network environment is increasing very rapidly in theses days. In this study we surveyed the success factors of the internet sites in which selling their agricultural product on the net. The results showed that average sales per month have positive correlation with success factors as numbers of each site members, visiting numbers of each sites per month, and sales numbers of each sites per month. To increase the quantity of sales, they should concentrate selling strategy on high quality products, and the web page of the business sites must be designed with user friendly and community supportive conditions. And to increase the repurchase rate, systemic management of consumer is required.

This study was performed to investigate the status of using personal computer(PC) and to develope strategy to improve PC utilization of Cactus Farmers. Sixty nine farmers are surveyed to collect data. Many farmers had intention to use PC to manage Cactus and have recognized that PC is required to manage farm and to improve their life quality. As a result of analysis on farmers' need for agricultural information, they highly demanded infor-mation on production skills, marketing information, overseas production trends, imports and exports information. Some farmers using or having intention to use software for Cactus farming want software to be developed and dis-tributed to support production technolog', labor management production cost and benefit analysis etc.

In order to measure a distribution of D.B.H, sample plots were established A-plot (100m×25m) and B-plot (90m×40m) located at Pyeong-sa-ri, Nag-an-myeon, Seung-ju-gun, Chennam, of elevation from 300m to 400m with medium-slope of south-east aspect. This Larix leptolepis stand was not carried out branch pruning operation and thinning operation since tress planted. Diameter of breast height were measured from standing tress of Larix leptolepis Gord by 2 cm rounding off method which plantation was set up arificially 19years ago on two sample plots. After finished diameter meassrement, the trees height, diameter of breast height, clear lenght and form height were measured from felling trees per diameter classes, and carried out stem analysis of one normal tree per diameter classes. The results obtained are follows: 1. Distribution of D.B.H. gave data as shown in table 1. 2. Relation between D.B.H (X) and Height (Y). Y=8.34312+0.38772X, r=0.76**, ??=1.098. 3. Relation between D.B.H (X) and Clear Length (Y). Y=7.40670+0.0610X, r=0.14, ??=1.443. 4.Relation between Height (X) and Clear Length (Y). Y=3.82138+0.3066X, r=0.32**, ??=1.379. 5. Relation between Height (X) and Form Height (Y). Y=2.43985+0.4913X, r=0.82**, ??=0.820. 6. The Stem Analysis of six normal trees gave data as ahown in table 10, 11, 12

A 44-year-old man treated with azathioprine, cyclosporine and prednisolone for 7.5 years after allogeneic renal transplantation was admitted because of exertional dyspnea, fatigue and pancytopenia which were found 3 months ago. He had been on hemodialysis for renal failure of unknown cause for 8 months before the renal transplantation. Bone marrow examination showed hypercellularity, erythroid hyperplasia and 7% of myeloblast, consistent with the diagnosis of myelodysplastic syndrome. Cytogenetic study showed chromosomal abnormalities:deletion of chromosome 5, monosomy 7, trisomy 8, monosomy 14 and deletion of chromosome 17. Immunosuppressive agents were discontinued and he was treated with transfusion, G-CSF, and combination chemotherapy including topotecan and Ara-C. Graft kidney function was normal before and after the treatment, but the clinical course was fatal because of leukemic transformation and eventually sepsis. Although therapy induced myelodysplastic syndrome was rare in renal allograft recipients, thorough evaluations including bone marrow biopsy and cytogenetic study are recommended in patients with anemia of unknown etiology.

사과의 구매의사에 영향을 미치는 예측요인 분석- 베트남시장을 중심으로
이철희 ( Lee Cheol-hi ),조성주 ( Jo Sung-ju ),박정운 ( Park Jeong-woon ),박동진 ( Park Dong-jin ),홍정식 ( Hong Jeong-sik ),윤영호 ( Youn Young-ho ) 韓國食品流通學會 2019 한국식품유통학회 학술대회 Vol.- No.동계
이 연구는 베트남 사과시장의 소비자 구매행동에 관한 것으로서 원산지 선호도, 한국사과의 이미지 및 품질만족도와 구매의사 간의 관계를 기술하고, 베트남 사과소비자들의 구매의사결정에 영향을 미치는 예측요인을 식별하려는 것이다. 표본은 베트남 사과 소비자 100명을 대상으로 수집한 데이터를 기초로 사과 구매의사가 있는 집단과 사과구매의사가 없는 집단 간이 사과의 이미지, 원산지별 선호도, 품질만족도에 대한 평균 차이 분석을 수행하고, 이들 변수간의 카이제곱 검증을 통하여 변수간의 관계를 기술하였다. 또 베트남 사과 소비자들이 사과를 구매할 때 구매의사결정에 영향을 미치는 예측요인을 분류 및 식별하기 위하여 로지스틱회귀분석을 실시하였다. 분석결과, 사과의 구매의향에 영향을 미치는 중요한 예측요인은 안전성이미지, 전반적인 만족도 및 내적 품질만족도(가격, 당도, 씹는 느낌(식감), 및 안전성)으로 식별되었다. 분석결과에 대한 시사점은 수출자 또는 생산자가 통제하기 어려운 사과의 품질 속성인 가격 당도 및 씹는 느낌은 단기간에 개선하기 어려운 반면, 한국 사과는 ‘안전한 사과‘라는 안전성 이미지 구축을 위한 새로운 포지셔닝 전략과 커뮤니케이션 전략을 포함하는 마케팅 전략수립이 요구된다. 제한된 표본사용으로 인해 과도한 일반화에는 한계가 있으며, 향후 표본의 수를 늘려 추가적인 확인이 필요하다.

지형모형(Digital Terrain Model)으로부터 지형을 렌더링하기 위해 광선 투사법을 사용할 수 있다. 본 논문에서는 저자들이 이전에 제안하였던 지형 렌더링 기법을 앤티에일리어싱을 포함한 몇가지 측면에서 확장한다. 또한 지형 렌더링에서의 앤티에일리어싱의 여러가지 측면을 논의한다. 지표 및 색상 재구축 모델에 대해 요약한다. 또한 여러가지 앤티에일리어싱 기법들을 그들이 적용되는 방향별로 분류하여 논의한다. 먼저 수퍼샘플링과 면적 샘플링을 포함한 수직 방향의 앤티에일리어싱 기법들을 논의하며, 마지막으로 수평 방향의 앤티에일리어싱 기법들에 관해 논의한다. We may use ray-casting methods to render terrain from digital terrain models. In this paper we enhance our previously-proposed terrain renderer in several ways, including application of antialiasing techniques. Also we examine various aspects of antialiasing in terrain rendering. We summarize surface and color reconstruction models. We also discuss several antialiasing techniques. We categorize the techniques according to the direction in which they are applied. First we discuss antialiasing methods along the vertical direction, including supersampling and area sampling. Finally we discuss several issues of antialiasing along the horizontal direction.
