The purpose of this study is to experiment and develop seamless-effect knitwear design using tubular-jacquard structure in order to find a new method of manufacturing knitwear and to suggest a new design. The study is based on changing the point of view about using the practical technique like the tubular jacquard which has been used mainly for expressing patterns. The result of experimenting this, a piece of fabric is able to being worn as a piece of garment. As for using circular structure of tubular jacquard, a body can be fitted into the big space between front and back part of fabric and seams can be made of small patterns of jacquard fabric. The silhouette, the drape and the result of the garment of this experiment are different from the ordinary outfit. Therefore, the study to find a new way of design and manufacturing should go on to suggest a different form and method.

Mobile IP는 현재의 인터넷에서 노드가 링크를 변화시킬 때 통신이 지속 될 수 있도록 이동성(Mobility)을 제공하기 위한 방안이다. Mobile IP는 MN(Mobile Node)이 HA(Home Agent) 와 FA(Foreign Agent)사이에서 링크를 변화시킬 때 CN(Correspondent Node)과 지속적인 통신을 할 수 있도록 한다. 그러나 FA에서 FA로 MN이 노드의 위치를 바꿀 때에는 핸드오프(Handoff)가 발생하여 패킷이 손실 될 수도 있다. 본 논문은 MN이 FA에서 다른 FA로 이동할 때 발생하는 패킷 손실과 순서변경에 대한 경우를 살펴 이를 해결하기 위한 Seamless 핸드오프 프로토콜을 기술하고 이를 검증한다.

최근에 제안된 심리스(seamless) 제 2상/제 3상 임상시험 디자인은 기존의 임상시험 디자인들과 비교하여 피험자수를 줄일 수 있을 뿐만 아니라 임상 개발 시간을 단축시킬 수 있다는 장점을 가지고 있어 임상시험연구자들의 많은 관심을 끌고 있다. 또한 제 3상 시험을 단독으로 진행 하였을 때보다 더 높은 검정력을 가질 수 있으므로 임상시험에서 매우 효율적이라 말할 수 있다. 본 논문에서는 제 2상에서 최고효과 용량군을 선정하기 위한 여러 가지 다중가설 검정방법들을 제시하고 제 2상에서 최고효과 용량군을 선정한 후에 제 2상과 제 3상을 결합하는 여러 가지 유의확률 결합검정방법들을 제시하였다. 또한 모의실험을 통해서 심리스 제 2상/제 3상 임상설계가 적용되었을 때 여러 가지 방법들을 비교함으로써, 제 2상/제 3상 표본의 크기 조합이나 분산의 크기가 다른 여러 가지 상황에서 가장 적절한 방법을 선택하는 가이드라인을 제시하고자 한다.

수치지도의 관리 및 운영에 필요한 유일식별자에 대한 연구는 기존의 국토지리정보원을 통하여 많은 연구가 수행되어져 왔으나 그 내용과 과정이 복잡하여 현실적으로 잘 적용되지 못하고 있는 것이 사실이다. 이를 극복하고 객체기반 연속수치지도의 원활한 관리를 위하여 객체기반연속수치지도 유일 식별자인 OSID의 도입이 필요하고 이를 바탕으로 객체기반 연속수치지도 관리체계에 OSID를 적용하고자 한다. 본 논문은 객체기반연속수치지도에 적용할 OSID의 기본구조를 기초로 하여 객체기반 연속수치지도 관리 OSID 시스템 체계를 설계하고, 수치지도의 관리 및 운영상 필요한 유일식별자를 부여하는 방법을 객체기반 연속수치지도에 적용하고자 한다.

MMS has been seen as the key application in its entry into the 3G mobile markets. Furthermore, the combination of WLAN and 3G wireless technologies will make MMS service more popular, bringing benefits to both service providers and their customers. To realize seamless MMS service over WLAN and CDMA2000 networks, we design and implement new platform architecture by reusing the existing standards and network elements at the same time. We employ loose coupling approach and Mobile IP approach to propose new platform architecture, interfacing MMSC with many existing components. Based on our platform architecture, we also present seamless MMS delivery implementations that can't be possible within the current MMS reference architecture. This paper will make a contribution for service providers to offer their customers with seamless MMS service over WLAN and CDMA2000 networks.

This paper proposes design and implementation for Seamless Handoff method between adapters in a system environment where both wired and wireless adapters are present First of all, by settingLayer 2 address of wired adapter to Layer 2address of wireless adapter, then generate virtual adapter on the above layer to make these two adapters operate on an IP address. Under the condition, when wired communication via the wired adapter gets disconnected while in service, wireless handoff occurs by mapping information on the wireless adapter to the virtual adapter. According to the method proposed in this paper, continuous session can be obtained even when handoff between wired and wireless adapters occurs at lower level in an application where both IP address and Port address are used to maintain session since If address does not change.

This study aims to seek knitting methods that can enhance the neck design of seamless knitwear and to find out how to improve the designs by comparing and analyzing the characteristics of the knitting methods used for v-neck pullovers. The investigator analyzed the characteristics of the knitting methods and assessed the wearing sensation by using six different pieces of clothing for the experiment. The results were analyzed based on a variance analysis (ANOVA). Among the items showing significant results, the Duncan-test was used for more intensive research. As a result, while using the basic pattern of knitting methods, Experiment Clothes A ended up binding on the back neckline, and not making the hem of back. Also, the neck was the widest. In the case of the special neck, Experimental Clothes B (1:1), which had the least number of the knitting course in relation to the knitting ratio, the bottom part of the back body had the most wrinkles. According to the result of wearing sensation, the front part, the side part, and the back part showed similar results (p<0.000) in all items. Specifically, the appearance of the Experiment Clothes A (normal) in both the front and rear aspects were evaluated as the best. In the case of the special neck, the Experimental Clothes F was ranked the highest, whereas the Experimental Clothes B (1:1) was ranked the lowest. Based on the results of the study, it seems possible to provide concrete and technical data for the planning of unique and productive designs. With regard to seamless knitwear neck designs, a comparative analysis of the knitting method of v-neck pullovers will be of practical use in the development and manufacturing of the product.

The purpose of the study is to derive an appropriate knitting method that can increase the appearance, wearability, and functionality through empirical research on the sleeve height knitting ratio of seamless knit wear. The study was conducted by producing seven types of experiment clothes according to knitting ratio to examine the characteristics according to the body armhole and sleeve height ratio. Specifically, after fit evaluatins, variance analysis (ANOVA) was performed to analyze the results of the evaluation, and the evaluated contents were converted into data. Among them, the items with significant results were intensively studied using the Duncan-test. The result showed that the height and the width of the sleeves vary depending on the knitting ratio. Test sweater A was the highest at 16cm, followed by test sweater B, test sweater C, test sweater D, test sweater E, test sweater F, and test sweater G at 4cm. The 1:1 ratio of test sweater A, was the highest, which is knitted in the same course as the body. The larger the difference in the ratio of body and sleeve, the lower the height of the sleeves. As a result of the appearance sensory evaluation, a significant difference was confirmed in the result values (p<0.001) from all items on the front, side, and rear. Specifically, the appearance of the test sweater B(2:4:2) on the front and test sweater C(2:4:3) on the side and rear side was the best. When the sleeves height is properly set, the ratio of the arm line to fit the design with a natural curve is analyzed as a very important factor. The results of this study are expected to be of practical use in product development and production that can increase the feeling when wearing and design satisfaction.
