  • This study was conducted to develop precision control system fur cold storage facility that could offer safe storage environment for green grocery. For that reason of neuro-fuzzy control system with learning ability algorithm and single chip neuro-fuzzy micro controller was developed for cold storage facility. Dynamic characteristics and hunting of neuro-fuzzy control system were far superior to on-off and fuzzy control system. Dynamic characteristics of temperature were faster than on-off control system by 1,555 seconds(123% faster) and fuzzy control system by 460 seconds(36.4% faster). When system was arrived at steady state. hunting was ${\pm}$0.5$^{\circ}C$ in on-off control system, ${\pm}$0.4$^{\circ}C$ in fuzzy control system, and ${\pm}$0.3$^{\circ}C$ in neuro-fuzzy control system. Hunting of humidity and wind velocity was also controlled precisely by 70 to 72.5% and 1m/s For storage experiment with onion, characteristics of neuro-fuzzy control system were tested. Dynamic characteristics of neuro-fuzzy control system made cold storage facility conducted precooling ability and minimized hunting.

  • The word play on h(e)art-hunting has become a virtual commonplace in criticism of Chaucer′s Book of the Duchess. Less widely discussed is the third meaning of ME herte, "hurt." The "hart"/ "heart" pun is, however, only implicit in the poem, while the rhyme of "heart" and "hurt" in lines 883-84 makes clear the close association of the terms for Chaucer. Earlier commentators insisted that this was in fact an instance of rime riche or "identical rhyme," but if it is so it is striking that it is the unique instance of the rhyme in Chaucer, whose works are full of occasions for hurt hearts. The essay argues that this is, instead, an instance of near-rhyme and that the confusion in scribal spellings of ME hurten(with ′u,′ ′0,′ ′i,′ ′y,′ and ′e′ ) suggests uncertainties about its root vowel that modem linguistic study has not clarified completely. If the rhyme of herte ("hurt") with herte ("heart") is, however, established by these lines in BD, then it is probably reasonable to ask about all the occasions where characters in the poem are hurt by emotional or physical distress. In the cases of A1cyone and the Man in Blak, the hurt is revealed plainly as the death of a loved one, and Alcyone′s death and the Man in Blak′s return "homwarde" offer contrasting responses to the realization and acknowledgement of their loss. In the case of the Narrator, however, the exact nature of his "hurt" is nowhere made clear and the questions this Jack of clarity raises for the reader remain unanswered when the poem declares its "hert-huntyng" done. Further examination of the Narrator′s character and his role in the poem may reveal him to be a physician himself in need of healing, and this reading of his character may identify him as an ancestor as much of Chaucer′s Pardoner as of the Pilgrim Narrator of Canterbury Tales.

  • 대부분의 해킹 과정에서는 장기간에 걸쳐 내부에 침입하고 목적 달성을 위해 우회접속을 이용한 외부와 통신을 시도한다. 고도화되고 지능화된 사이버 위협에 대응하는 연구는 주로 시그니처 기반의 탐지 및 차단 방법으로 진행되었으나, 최근에는 위협 헌팅 방법으로 확장되었다. 조직적인 해킹그룹의 공격은 장기간에 걸쳐 지능형 지속 공격이면서, 우회 원격 공격이 대부분을 차지한다. 그러나 지능화된 인지 기술을 활용한 침입 탐지 시스템에서도 기존의 침입 형태에만 탐지성능을 발휘할 뿐이다. 따라서, 표적형 우회 원격 공격에 대한 대응은 기존의 탐지 방법과 위협 헌팅 방법으로도 여전히 한계점이 있다. 본 논문에서는 이러한 한계점을 극복하기 위해 조직적인 해킹그룹의 표적형 우회 원격 공격 위협을 탐지할 수 있는 모델을 제안한다. 이 모델은 우회 원격 접속자의 원점 IP 확인 방법을 적용한 위협 헌팅 절차를 설계하였고, 실제 국방 정보체계 환경에서 제안한 방법을 구현하여 유효성을 검증하였다.

  • Dynamic analysis of the KTX can predict the dynamic motions in test drive. In this study an analytical model of the KTX is developed to find the critical speed. The numerical analysis for the nonlinear equation motions of 17 degrees of freedom shows the running stability and the critical speed due to the hunting motion of the KTX. Also, the vibration modes of the KTX are calculated using the ADAM/RAIL software, which show that the critical speed occurs for the yawing modes of the car body and the bogie. Finally, this paper shows that the critical speed of the KTX could be changed with the modifications of the design parameters of wheel conicity or wheel contact length.

  • This paper discusses the numerical study on the stability of the high-speed EMU by developing its lumped parameter model including the effect of the creepage. The 6, 10 and 14 degrees-of-freedom (DOF) lumper parameter dynamic models are developed and the critical hunting speeds calculated from each model via Matlab software are analyzed and compared. It is demonstrated that the critical hunting speeds decrease while the degrees-of-freedom increase. In addition, the parametric study is conducted to extract major design parameters to influence on the stability of the high-speed EMU.

  • The intent of this study is to suppose the time of engraving of Bangudae-rockgraving-picture and the change of the ancient soci-ety related to the Postglacial transgression and regression in the Ulsan Bay. Main results can be summed up as follows; 1. It is supposed that the shoreline in the maximum Postglacial transgression of the Ulsan bay has arrived to Gulhwa-Ri about 14km upstream from the present Taehwa River mouth. 2,.This transgression has occurred about 6,000-5,000 years ago. The prehistoric men around the Bangudae had hunted the whale near the inner bay From this time the people had begun to engrave pictures on the Rock of Bangudae for the ceremony and instruction of the whale hunting,. 3. Since then the shoreline had regressed and the whale hunting area had moved to distant area from the residence and the number of the captured whales had diminished. The whale hunting society had been transformed to the overland animals on the Bangudae-rockgraving- pictures had gradually increased.

  • The generators of a small size below 100Kw are often used as power suppliers for emergency only in most domestic telecommunication companies. Serious twisted waves occur due to the inflow of harmonies from the generator into a S-type rectifier. And the increasing by stages of load upon the rectifier end up a stoppage of power supply during the serious hunting, which makes it difficult to supply power securely on the other part as well as that of communications. In case of long time of power failure the generators of a small size will be essential because the battery for emergency has a limit in capacity. Therefore it is necessary to solve the problems concerning the generators. This study is focused on the identifying and solving the problem including use of SCR elements connected to the generators.

  • This study is about the similarities and the individualties of the traditional costumes in the ruling classes of Koguryo(高句麗), Bakjae(百濟), and Shilla(新羅). The analysis is based on the views of historical reformation on$\boxDr$Sam-gooksagi(三國史記)$\boxUl$Bongi(本紀). The costumes that were worn by the governing classes are categorized by the following, official duties, wars, ceremonies, and recreations(hunting). Up to the present time, there has been a great tendency to emphasize the similarities of the Three Kingdoms' costumes among most of academic researchers. However, the conceptions of individualities of the costumes among the Three Kingdoms were conceived by the facts that geological environments, political systems, social traditions, social aspects, and foreign affairs. The Three Kingdoms had different official rank systems along with official costume systems. Monopolization of official positions of the ruling parties tried to show their dignity and authority through styles of their costumes. The costumes of Koguryo were greatly differentiated by geographical regions ; One direct example is cheak of Pyoungyang and Anak regiona was named as official hats of rulling parties of Kokuryo. However, in this study, the cheak was viewed as a product of influences of Chinese costume. Further-more, the laguan was named as mooguan. Costumes of ceremonial occasions were heavily decorated to symbolize dignity and auth-ority. Metal ornament of headgear and belt, metal shoes were con-sidered as ceremonial costumes. the tight hunting costumes of Koguryo shown in mural pain-ting costumes of Koguryo shown in mural pain-tings were presumed to be spring and autumn clothing. Excavated from Neungasnlee, the hunting costumes inscribed in the gold incense burnner were confirmed as hunting costumes of Bakjae. The individuality of the costumes of the Three Kingdoms could also be supported by the fact that they had different climates. The temperature difference between Gipan region and Kyoungjoo(慶州) region was emphasized. Especially winter clothing would have had a big difference in style than the summer clothing. Through the research summarized above, this study was able to confirm that each of the Three Kingdoms had developed individualized costumes based on their geographical, cultural and environmental factors. Furthermore, through this study, it was possible to find out the difference as well as the similarities of their costumes according to each of their people's sociopolitical status, awareness of indepen-dence, andunique historical and traditional charactoristics.
