The purpose of this study is to comparison on the sizing system in silver apparel brands with the KS standards. For the comparison research, 3 women's wear brands(suit style, knitted suit style, casual style) which were different apparel style on occasion in madame-zone of department stores were selected. The subject of investigation of sizing system of these brands were the label. The results of the sizing system of silver apparel brands as compared with the KS standards were as follows: 1) For the upper wear of suit style, it is larger than KS standards that size of height is $5{\sim}15$ cm. 2) For the lower wear of suit style, suitability of size of hip circumference is lower than KS standards. 3) For the casual style, it is larger than KS standards that size of height is $10{\sim}20$ cm.

Because of the rapid growth of the mobile communication, the need for the mobile internet access has grown up as well. since the current mobile communication network, however, is optimized for a voice communication system, which exclusively occupies a channel for a given time, it is not suitable for variable rate packet data. In order to support the mobile internet access, it is essential do design a reasonable packet switching network which supports the mobility. Since mobile packet network has longer latency, high speed switching and QoS are required to meet the user's requirements. In this paper, we suggest an resonable way to construct a network and its operation procedures utilizing GPRS(General Packet Radio Service) network and MPLS(Multi Protocol Label Switching) to provide a high speed switching and QoS mobile internet access. GPRS is used as a network which supports the mobility and MPLS guarantees the QoS and high speed IP protocol transmission based on the ATM switching technology.

링크드오픈데이터를 통해 다양한 분야의 RDF 데이터가 공개되고 있으며 그 양이 지속적으로 증가하고 있다. RDF 데이터는 그래프 형태이기 때문에 대용량 RDF 데이터를 효율적으로 관리하기 위한 그래프 데이터베이스에 대한 연구가 중요하다. 2개의 RDF 리소스가 그래프 상에서 연결됐는지 여부를 알아내는 기능은 RDF 요소간 연관관계를 식별하는 데에 관련이 있기 때문에 그래프 데이터베이스의 중요한 기능 중 하나이다. 대용량 그래프 데이터에 대한 그래프 도달가능성을 빠르게 처리하기 위해서 2-Hop 레이블링 변형들이 제안됐다. 최근에 2-Hop 레이블 크기를 줄이기 위해 2-Hop 레이블링이 진행되기 전에 노드 아이디를 부여하는 방법이 제안됐다. 하지만 그래프의 지역 정보만을 활용하기 때문에 복잡한 형태의 그래프에 대해서는 비효율적이라는 문제점이 있다. 본 논문에서는 그래프의 전역 정보를 반영할 수 있는 Topological Sort를 활용한 노드 아이디 부여 기법에 대한 설계를 제안한다.

MPLS LER is located at the boundary of MPLS domain as an ingress or an egress router and plays a role in connecting with the existing Internet. Among the components of the MPLS LER, forwarding engine(FE) is a key device which assigns a label to an IP packet by analyzing the destination address of its header in order to enter the MPLS domain, or restructures the cells from MPLS domain into IP packet by reversely processing. In this paper, we investigate the design of FE by analyzing the traffic performance of its components and estimate the IP packet processing capacity of a FE using queueing model and simulation. It is found that the maximum IP packet processing capacity of the Forwarding Engine is about 150,000 packets/sec.

The first four generations of computers are all based on a single basic design: the Von Neuman Processor, which is sequential and does one operation at a time. Efforts to develop concurrent or parallel computers have been carried on for many years. Data flow approach is significant in these efforts to make high speed parallel machines and expected a great deal of parallelism. In this paper we propose a preliminary data Flow Machine Model operating asynchronously on the base of Node Labelling. We introduce a concept of Node Labeling for this purpose which is relevant to the Data dependency and Parallelism. And we explain how the Node Tokens are fired in the proposed system.

지리정보시스템(GIS)에서 사용하는 지도는 여러 가지 목적의 응용 프로그램이나 지도의 축척등에 의해 서 다양하게 나타난다. 본 논문은 지리정보 시스템에 사용되는 지도중에서 관광안내지도를 대상으로 최적의 레이블링과 아이콘 표시방법을 통하여 관광지도 정보를 최적화하여 표현하기 위한 논문이다. 이를 위하여 서울시내의 여러 가지 관광버스의 노선도를 분석하여 이를 최적화된 방법으로 배치하고 표현하는 위한 방법을 연구하였다. 복잡한 버스의 노선은 주요 시설물을 중심으로 선분 간략화 알고리즘을 통하여 간략화 하였으며 간략화된 노선에서 중첩되는 레이블은 레이블 재배치 알고리즘을 이용하여 재배열하였다. 이러한 방법을 통하여 지리정보 데이터베이스로부터 자동화된 방식으로 구조화된 지도를 손쉽게 생성하는 방법을 제시한다.

In order to provide seamless wireless Internet service, the basic mobile IP protocol should be enhanced to solve packet loss problem from large registration latency because frequent handoffs occur in cellular networks. In this paper, we suggest a new micro-mobility management protocol based on MPLS while supporting Qos, and evaluate its performance using simulation. We use MPLS label switching techniuqe in cellular access networks to simplify location management and speed up packet transmission. We adopt context transfer procedure to minimize the delay needed to attain prior level of service after handoff Packet loss can be minimized during handoff by transmitting received packets from old BSLER to new BSLER using a spliced LSP between them. Simulation results show that the proposed MPLS-based micro-mobility management protocol provides a seamless handoff and supports QoS of user traffic.

차세대 인터넷의 요구 사항을 만족시켜 주기 위하여 IETF에서는 MPLS(Multiprotocol Label Switching) 기술을 표준화하고 있다. MPLS는 ATM과 흡사한 레이블을 사용하여 레이블 스왑핑에 의한 포워딩을 수행하므로 IP 패킷을 매우 빠른 속도로 전달해 줄뿐만 아니라 ATM 망에서의 다양한 질의 서비스 제공을 가능하게 하여 기존의 ATM 망의 활용도를 증가시킨다. 본 논문에서는 현재 개발 진행 중인 ATM 스위치 기반 MPLS LER 시스템에서 성능 관리 기능을 위한 구조를 제시하고, 구현 내용을 기술한다. 본 시스템에서 제공되는 통계 대상에는 MPLS 연결인 LSP 트래픽과 Non_ MPLS 도메인의 연결인 가입자 트래픽 및 제어 트래픽 등이 있다.

Recently, as various examples of machine learning have been applied in the healthcare field, deep learning technology has been applied to various tasks, such as electrocardiogram examination and body composition analysis using wearable devices such as smart watches. To utilize deep learning, securing data is the most important procedure, where human intervention, such as data classification, is required. In this study, we propose a model that uses a clustering algorithm, namely, the K-means clustering, to label body fat according to gender and age considering body size aspects, such as chest circumference and waist circumference, and classifies body fat into five groups from high risk to low risk using a convolutional neural network (CNN). As a result of model validation, accuracy, precision, and recall results of more than 95% were obtained. Thus, rational decision making can be made in the field of healthcare or obesity analysis using the proposed method.
