인터넷을 이용한 이메일은 이제 소수의 통신 수단이 아닌 일반인이 널리 사용하는 기본적인 통신 수단으로 자리잡고 있으며, 이에 따른 스팸메일의 피해 규모도 날로 커지고 있다. 현재 다양한 방법의 스팸메일 차단 방법이 제안되고 수행되고 있으나 다양해지는 스팸메일에 대응하기에는 역부족이다. 이 논문에서 제시한 스팸메일 차단 방은은 수집, 빈도분석과 차단의 3단계로 구성되며, 수집되는 스팸메일을 이용하여 다양한 스팸메일에 대응할 수 있으며, 변화하는 스팸메일의 형태에 대해서도 대응할 수 있는 구조를 가지고 있다.

통계학을 좀 더 쉽게 이해하며 흥미를 가지고 접근할 수 있도록 하기 위해 다양한 통계교육 방법의 연구가 계속되어지고 있다. 그러나 동계교육에 있어서 항상 겪는 어려운 점 중의 하나는 학생들이 쉽게 받아들일 수 있는 실제 자료가 많지 않다는 것이다. 이는 학생들에게 통계학을 현실과 전혀 관계없는 학문으로 인식시키며 학습 의욕을 저하시키고 통계학을 재미없는 학문으로 인식하게 되는 부정적 결과를 낳게 하였다. 본 연구에서는 웹과 데이터베이스를 활용한 자료 수집 및 공유 프로그램을 활용하여 수업에서 현실감 있고 학생들과 관련이 높은 자료를 활용할 수 있도록 하고 엑셀을 활용하여 학생들이 통계학의 개념과 응용에 더 집중할 수 있는 통계교육 수업방안을 제안한다.

The purpose of this study is to analyze the concept and characteristics of parody, and consider how parody was reflected in Thom Browne's collection centering on the expressive method. Thus, this study will attempt to shed new light on the creative possibility and artistic value of parody in men's fashion design. The methods are as follows. The ideas, characteristics and expressive methods that represent parody was considered by referencing various related books, papers, art critiques, etc. Based on this theoretical study, a case of Thom Browne's collection (Thom Browne menswear: 2004 S/S-2012 F/W) was observed to find types of parody, attributes and significance. Photo material was collected through websites such as www.thombrowne.com, www.style.com, etc. The type and characteristics of parody expressed in Thom Browne's collection was considered in the following aspects: imitative parody, critical parody and pastiche parody. Through such consideration, it was possible to realize the fashion designs that adapt Thom Browne's parody are very deliberate and calculative. The designs convey exaggeration, destruction of form, emphasis on discontinuity, transition into attraction, aesthetics of unfamiliarity, characteristic aspects of irrationality and contradiction. Through the study, it was possible to see Thom Browne's collection with parody adaptation shaping new creativity and broadening formative aspects in fashion design.

In this paper, we have investigated on collection efficiency of fine particle of glass fiber-filter bag according to the surface treatment. The solution consisted of polytetrafluoroethylene(teflon), graphite powder, silicon resin and water was used as a basic surface treatment agent. Tensile strength of glass filter-bag increased with up to 3hrs and then decreased with surface treatment time. Tensile strength and initial modulus of the glass fiber-filter bag treated by iodine after basic surface treatment for 3hrs were lower than those of basic surface treatment for 3hrs, however collection efficiency and fracture strain were higher than those of basic surface treatment for 3hrs. Glass fiber-filter bag with lower initial modulus and more strain will be extend the durable period and the one treated by iodine after basic surface treatment 3or 3hrs is expected high collection efficiency of fine particle. This method makes it possible to manufacture glass fiber-filter bag of the optimum condition.

This study was conducted to understand the effects of weather and tapping date on yield and quality of lactree(Rhus verniciflua) sap yield showed a significant positive correlation with the minimum temperature of one day before sap collection at 1% level and with theminimum humidity of theday of sap collection at 5% level. However, the differences between the maximum and the minimum temperatures and humidities of the day of sap collection were negatively correlated with the sap yield at 5% level. Multiple regression analysis indicated that the minimum temperature of one day bofore sap collection and the minumum humidity of the day sap collection were important factors for increasing sap yield. The high sap yield of lactree by Japanese tapping method was recorded during mid-July and early August. Seasonal variation in lactree sap constituents was observed. The sap collected on 15th of August contained the highest urushiol content (68.3%) and the lowest water content resulting in high quality of lactree sap. By reversed-phase HPLC analysis, fove urushiol components were separated from each other depending on the number of doulbe bonds in the side-chain , and seaxonal variation of urushiol composition was noticed. The 3-C15 triene content fo the sap collected on 5th of July was the highest(77.56%) indicating the major component of urushiol which affects lactree sap quality.

This study was performed in order to simplify the operation and minimize stress of donor and be readily available in the field with low cost and high quality embryos using the Direct Embryo Collection (DEC). Donors, at random stages of the estrous cycle, received a CIDR. 7 days later, 200 mg FSH was treated with 40, 30, 20, 10 mg FSH levels in declining doses twice daily by intramuscular injection for 4 days. On the 3rd day administration of FSH, 25 mg $PGF_2{\alpha}$ was administered and CIDR was withdrawn. After FSH injections were complete, donors were artificially inseminated twice at 12 hr intervals. The donor cattle received 250 ${\mu}g$ GnRH at time of 1 st insemination and embryos were recovered 8 days after the 1st insemination. Embryo collection from superovulated donors was performed to flushing by non-surgical methods of 3-way, 2-way and DEC (l-way). The average number of recovered embryos were 11.25${\pm}$0.63, 12.5${\pm}$0.65 and 11.75${\pm}$0.48 from operations of 3-way, 2-way and DEC methods, respectively. There were no significant differences among the embryo collection methods. Also, The average number of transferable embryos were 6.25${\pm}$0.48, 7.25${\pm}$0.48 and 7.25${\pm}$0.63 from each embryo collection procedures. The number of transferable embryos was no differences among the 3-way, 2-way and DEC methods, respectively. Meanwhile, the ratio of transferable embryos for all recovered embryos from DEC methods was higher as 61.7 % than 55.6 %, 58 % from methods of 3-way, 2-way. And the flushing solution required for recovering embryos by DEC method was significantly lower as 0.28${\pm}$0.32 1 than 1.8${\pm}$0.12 1, 1.75${\pm}$0.10 1 from 3-way, 2-way methods (p<0.05). Also, the time required for recovering embryos by DEC methods was significantly lower as 27${\pm}$2 min than 51${\pm}$3, 45${\pm}$2 min, respectively (p<0.05). In conclusion, these results suggest that DEC method for embryo collection may be effectively used for production of in vivo embryos using less flushing solution and, it might be effectively available in the field compared to conventional embryo recovery methods using 3-way or 2-way balloon catheter.

Holstein cow ovaries obtained at a slaughterhouse were used to study the influence of the oocyte collection methods (slicing, puncture, aspiration I and II) on recovery efficiency and subsequent in vitro maturation and embryonic development competence of immature oocytes recovered. In the slicing method, the whole ovarian was chopped into small pieces with a surgical blade. In the puncture method, the whole ovarian surface was punctured by 18-g needle. In other 2 aspiration methods, collected oocytes by aspirating from the visible follicles using an 18-g needle attached to a 5 ml syringe (aspiration I) or using a constant negetive pressure (-80 mmHg) with a vacuum pump (aspiration II). The oocytes were classified into 4 classes on the basis of the morphology of cumulus cells and cytoplasmic appearance of oocyte. Slicing ($9.6{\pm}0.4$) and puncture ($9.7{\pm}0.4$)yielded a larger number of oocytes per ovary than other two aspiration methods (aspiration I and II were $5.8{\pm}0.3$and $5.6{\pm}0.4$, respectively) (p<0.05). The number of the highest quality oocytes (grade A) per ovary was significantly higher in slicing ($4.2{\pm}0.2$) and puncture ($4.6{\pm}0.1$) methods than in other methods (aspiration I and II were $1.2{\pm}0.2$ and $1.4{\pm}0.2$, respectively) (p<0.05). The rate of nuclear maturation of the highest and higher quality oocytes (grade A and grade B, respectively) was not affected by the oocytes collection methods. The oocytes collection methods also did not influence subsequent embryonic developmental competence after in vitro fertilization with M II stage oocytes. It is concluded that slicing and puncture methods of the ovaries can be used as an alternative techniques to aspiration by the syringe or vacuum pump.

사이버 공간 내 디지털 증거 데이터는 수정 및 삭제되기 쉬우며 실시간으로 변경사항이 반영되므로 사건 발생 시점 이후 증거 데이터의 빠른 획득이 필요하다. 클라이언트 측에서의 증거 수집은 별도의 행정절차로 인한 시간 지연 없이 데이터를 획득할 수 있다는 장점이 있지만, 대용량 데이터의 수집에 있어서는 마찬가지로 수집 시간 지연 문제에 취약하다. 따라서 본 논문에서는 사이버 공간 내 주요 웹 기반 서비스를 중심으로, 클라이언트 측면에서의 자동화 된 증거 수집 방식을 제안하여 대용량 데이터에 대한 효율적인 증거 수집이 가능하도록 한다. 나아가 제안한 방식을 사용하고 수집한 디지털 증거의 법정제출시점까지의 무결성을 보장하는 사이버 공간 내 디지털 증거 수집 시스템을 제안한다.
