There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

벼 종실의 단백질 함량 및 조성은 식미에서 매우 중요한 형질로서, 우리나라 벼 유전자원의 종실 단백질 조성의 특성을 평가하고자 재래종 벼 390점, 샤레 46점 및 앵미 105점을 공시하여 SDS-PAGE방법으로 조사한 결과는 다음과 같다. 1. 우리나라 벼 유전자원의 단백질 패턴은 60kD 및 13kD의 단배질 분포에 따라 총 24개형으로 구분되었다. 2. 저장 단백질 중 60kD의 밴드패턴에 의한 분석에 의하면 앵미 및 샤레벼의 63%, 재래종의 91%, 육성종 100%가 진한 밴드패턴을 보였다. 3. 저장단백질 13kD밴드의 패턴에 의해 6가지 형태로 구분되었으며, 대부분의 accessions은 13kD-a 및 13kD-b사이에 추가적인 밴드가 관찰되었다. Protein contents and their composition are very important in controlling rice quality. A total of 633 rice (Oryza sativa L.) varieties/lines consisting of 390 landraces, 46 Share and 105 Red rice weedy type collection, and 92 improved varieties were analyzed for endosperm storage protein evaluation using single seed of each accession. Proteins were separated by the Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). The 24 different types were developed based on the polypeptide banding patterns of 60kD and 13kD proteins. In the 60kD polypeptide banding pattern, almost 63% of Red rice and Share collection showed thick band intensity, while 91.1% of landraces and 100% of improved varieties had weak band intensity. Six types were discriminated at the near 13kD polypeptide by the intensity and migration mode. Most of accessions had two bands at prolamin of 13kD-a and 13kD-b, but one band was detected between 13kD-a and 13kD-b of the 21 accessions of the Red rice collection and five improved varieties.

통계적 기법을 이용한 RFM 모형 비교분석

이용구,최희경 중앙대학교 수학통계연구소 2002 수학통계논문집 Vol.- No.9

RFM 모형은 그 원리가 매우 간단하고, 실제로 높은 예측력을 보이고 있기 때문에 상당히 광범위하게 사용되고 있다. 그러나 세 요소에 대한 가중치 부여 기준은 불분명한 상태이다. 본 논문에서는 기존에 업계에서 쓰이고 있는 전통적 RFM모형의 장단점을 찾고, 이와 함께 가중치를 부여하는데 있어서 통계적 기법(요인분석과 로지스틱 회귀분석)을 이용한 RFM 모형을 제시하였다. 결과적으로 앞의 전통적 모형보다는 통계적 기법을 이용한 RFM 모형의 가중치를 계산하는데 더 좋은 모형이라고 여겨진다. 이는 전통적인 모형이 갖고 있는 임의적인 변수의 세분화라는 단점을 보완하고 있을 뿐만 아니라, 모형3에서는 반응변수 없이 모형을 구축할 수 있다는 장점도 갖고 있다. 앞으로 통계적 기법을 이용한 RFM 모형에 관한 많은 연구가 있어야 할 것으로 생각된다. RFM score is a way to evaluate the customer value based on the three factors; R(Recency), F(Frequency), and M(Monetary). To calculate the score, we have to combine the above given three factors. But each factor has different measuring unit, and it is not easy to find the weight of each factor for calculating the score. Traditionally they calculate the score based on the categorization of each factors. But based on this method, we cannot calculate the score of individual customers. In this research, we have tried to calculate the RFM score based on the statistical methods, such as factor analysis and logistic regression method. In this methods we can calculate the score of the individual customer. We have also tried to compare the statistical methods with traditional ones by applying the models to real data set.
