Baby walkers have been a major cause of injuries in young children. The main purpose of this study is to identify the pattern of injuries associated with baby walker. The data ore collected from May 13 to June 15, 1998 from 438 mothers who have used or are using baby walkers for their children aged average 6 month old(range 1-33 month). It was founded that 19.2%(84 infants) of these children had walker-related accidents. The types of injuries included ‘falling down’(52.4%), ‘tiping over’(21.4%), ‘being crashed into the wall’(17.9%), and burns(1.2%). These injuries predominantly involved the head and neck region(88%). The majority of injuries were minor, and most injuries occured at home with the mother present. The most common reason to use the baby walker was to keep the infant happy and occupied. Although many parents used walker to promote walking, there was no supportive evidence that walkers helped babies learn to walk sooner. In conclusion, injuries among infants who use walkers are minor, but common. Also, baby walkers may cause a fatal min to some infants. Therefore, child safety warning label policies, anticipatory safety guidance and quality control of infant walkers are needed to prevent injuries associated with a infant walker.

본 논문에서는 Wi-Fi신호로 제어되는 융합형 라벨기 설계에 대하여 기술하였다. 현재 산업체에서 사용되는 라벨기는 산업현장에서 단독 장비로만 사용되고 인터넷이나 다른 네트웍 연결을 가지고 있지 않아서 라벨기가 수집한 자료를 전송하는 기능이 없어서 매우 불편하였다. 본 연구에서는 라벨기가 작업한 라벨의 종류와 사용량을 실시간 Wi-Fi를 사용하여 서버 컴퓨터로 전송할 수 있도록 정보통신(IT) 융합기술을 이용하여 설계하였다. 이러한 융합형 라벨기 시스템은 서버 컴퓨터에서 실시간으로 작업량과 작업상태를 파악할 수 있어서 기존 라벨기를 사용하는 경우보다 작업능력을 향상시키고 실시간으로 품질을 파악할 수 있게 되었다.

Transfer printing is a method to combine printing and dyeing technology by the use of sublimation. It is an environmentally-friendly printing method that saves costs, reduces the production processes by the omission of the washing process, and saves time by maintaining quality. Due to the development of transfer printing, a high value added printing technology is available now but color fastness to sublimation of the printing products is still low since there are few dyes that have an affinity to the fabrics and the application technology is still inadequate. Specially, in case of high concentration black dyes, eco-label type black dyes, which is a substitution for general dispersal dyes, have been developed while general dispersal black dyes are still used, creating issues such as color differences on the surface and back side of the fabrics and contamination by friction after transfer printing. There are also some restricted substances such as allergens. To address these issues, high concentration black dyes and application technology that are environmentally-friendly and that have over 16 K/S through the use of single dyes with excellent color fastness, fixation ability, and similar melting temperature were developed for this study.

This survey was conducted to compare food habit and food service satisfaction of high school students in urban and rural areas. The questionnaires were collected from 130 students in Daejeon and 140 in Geumsan. 19.8% of students skipped breakfast because of no time(48.7%), just habit(28.2%), no appetite(20.5%), for weight control(2.6%). The dietary behavior of rural students was better than city in taking snacks and light meal(p<0.05). For health they concerned highly about nutrition label expiration date of processed foods(72.3%) and least in considering nutrition than taste & price(37.9%). The satisfaction of food served was highest in nutrition(3.31), and taste(3.28), smell (3.23), color(3.03), temperature(3.02). The food service satisfaction of rural students was higher than city in proper temperature(p<0.001), nutrition(p<0.01), color(p<0.001). The satisfaction of rural students was higher than city in quantity of bap & side dishes, quality of food materials(p<0.001). The satisfaction of rural students was higher than city in convenience of dining hall, rapidity of food distribution, offer of nutrition information, sanitation of utensils & meals(p<0.001). It is suggested that school dietitian in city should be more concerned about sanitary food service based on students' dietary life & preference.

Spectral segmentation is a major trend in image segmentation. Specially, constrained spectral segmentation, inspired by the user-given inputs, remains its challenging task. Since it makes use of the spectrum of the affinity matrix of a given image, its overall quality depends mainly on how to design the graphical model. In this work, we propose a sparse, multi-layer graphical model, where the pixels and the over-segmented regions are the graph nodes. Here, the graph affinities are computed by using the must-link and cannot-link constraints as well as the likelihoods that each node has a specific label. They are then used to simultaneously cluster all pixels and regions into visually coherent groups across all layers in a single multi-layer framework of Normalized Cuts. Although we incorporate only the adjacent connections in the multi-layer graph, the foreground object can be efficiently extracted in the spectral framework. The experimental results demonstrate the relevance of our algorithm as compared to existing popular algorithms.

An ASCII encoding of Korean has been developed for extended phonetic transcription of the Speech Assessment Methods Phonetic Alphabet (SAMPA). SAMPA is a machine-readable phonetic alphabet used for multilingual computing. It has been developed since 1987 and extended to more than twenty languages. The motivating factor for creating Korean SAMPA (K-SAMPA) is to label Korean speech for a multilingual corpus or to transcribe native language (Ll) interfered pronunciation of a second language learner for bilingual education. Korean SAMPA represents each Korean allophone with a particular SAMPA symbol. Sounds that closely resemble it are represented by the same symbol, regardless of the language they are uttered in. Each of its symbols represents a speech sound that is spectrally and temporally so distinct as to be perceptually different when the components are heard in isolation. Each type of sound has a separate IPA-like designation. Korean SAMPA is superior to other transcription systems with similar objectives. It describes better the cross-linguistic sound quality of Korean than the official Romanization system, proclaimed by the Korean government in July 2000, because it uses an internationally shared phonetic alphabet. It is also phonetically more accurate than the official Romanization in that it dispenses with orthographic adjustments. It is also more convenient for computing than the International Phonetic Alphabet (IPA) because it consists of the symbols on a standard keyboard. This paper demonstrates how the Korean SAMPA can express allophonic details and prosodic features by adopting the transcription conventions of the extended SAMPA (X-SAMPA) and the prosodic SAMPA(SAMPROSA).

최근 메쉬 네트워크는 다양한 분야에서 사용되고 있다. 그러나 메쉬 네트워크는 무선 전송의 특성으로 인한 제한적인 대역폭을 제공하며, 특히 단일 채널로 구성된 메쉬 네트워크의 경우 다중 홉 전송 시 전송률 저하 문제 등이 발생한다. 이러한 문제를 해결하고 QoS(Quality of Service)를 제공하기 위해 다양한 라우팅방식이 제안되어 왔다. 본 논문에서는 MPLS(Multi Protocol Label Switching)를 적용하여 QoS를 제공하는 MPLS 메쉬 네트워크 구조를 제안한다. MPLS를 적용한 메쉬 네트워크를 통해 하부 QoS 제공방식과 무관하게 상위 응용계층에서의 경로관리가 용이해지며 트래픽관리가 용이해진다. 본 논문에서는 IEEE 802.11e 표준을 적용하여 트래픽에 대한 차별적인 서비스를 제공하도록 MPLS 적용 메쉬 라우터를 설계하고, 구현 및 실험을 통하여 동작을 검증하였다.

Ordinary biological methods of evaluating protein quality are subjected to various sources of error, such as preliminary feeding, body weight of the animals, length of feeding period, endogenous nitrogen metabolism, etc. (1). Wide variations in the reported data may be partly due to this fact. The author postulated that by applying labelled protein these shortcomings may be avoided and that a balance study using nitrogen-15 would give most reliable data, uninfluenced by other factors which are unavoidable in ordinary balance studies using unlabelled nitrogen (2). However, the most important prerequisite for testing this assumption is to obtain labelled protein. As it has been known long since that chlorella contains a large amount of protein and can be easily cultured in quantity (3, 4), it was thought that labelled protein might be obtained by adding $N^{15}$ into the culture media. In this study it has been tried to find out, therefore, whether it is possible to obtain labelled protein by incorporating $KN^{15}\;O_3$ into the culture fuid and at what stage of growth the incorporation of the label into chlorella occurs.

현재 이동통신망의 주요 서비스는 기존의 음성 서비스뿐만 아니라 데이터 서비스의 비중이 점차 늘어가고 있다. 그리고 데이터 서비스는 다양한 미디어가 결합되는 멀티미디어의 형태로 발전하고 있다. 그러나 한재의 네트워크는 멀티미디어 데이터를 기존의 최신형 데이터와 동일하게 처리하여 사용자가 요구하는 QoS를 만족시키지 못한다. 따라서 본 논문에서는 QoS를 제공하는 MPLS기법을 Core망에 적용하여 멀티미디어 데이터의 QoS를 보장할 수 있는 네트워크 구조를 제안한다. 특히 MPLS기법을 Core망에 적용한 경우의 throughput을 시뮬레이션 시간 및 사용자 수의 변화에 따라 비교 분석한다.
