In 1995, the costumes were restored in an unknown woman's tomb at the Jeonju Lee's family cemetery in Gapyeong, Gyeonggi-Do, and there are currently nine items remaining. In this study, we first introduced these 9 relics to academia and analyzed the morphological characteristics of the costumes. We also estimated the time and person of burial compared with costumes unearthed from other burials. Jeogories (short jacket) are all four items. One of these items was unusual in shape, and the upper part of the seop (gusset) was wrinkled and shaped. This type of Jeogori appears only till the 1520s in other tombs. There are also two skirts, one of which is characterized by a superimposed pattern. The top and bottom / middle part of the skirt were rolled up, and the skirt, which was double-rolled up in this way, was first discovered. An analysis of the shape of Jeogori and skirt indicated that the person buried in the Jeonju Lee's family tomb was believed to have survived until the early 16th century. Based on these estimated periods, as a result of looking at the genealogy of Jeonju Lee's family, it was concluded that the tomb was probably a woman named Lee Geum Myeong (李金命) born in the mid-15C and died between the late 15C and the early 16C.
지능형 주택을 위한 구성원 식별 및 위치 이동 감지 센서 네트워크 시스템

지능형 주택의 상황인지 서비스를 위해서는 거주자의 현재 위치를 파악하는 것이 필수적이다. 이를 위해 본 논문에서는 사용자에게 별도의 장치 소지를 요구하지 않으며 특정 문에 대한 출/입 행동과 같은 위치 이동과 그 사람이 누구인지를 식별하는 센서 네트워크 시스템을 제안한다. 새롭게 개발된 센서노드는 선행 연구 결과[1]의 짧은 동작 수명 문제를 해결한 것으로 2개의 초전형(PIR) 센서와 초음파 센서, 그리고 2.4 ㎓ 무선 통신 모듈로 구성된다. 제안된 구성원의 식별 방법은 초음파 센서를 이용한 구성원의 키 차이를 이용한다. 거주자의 위치 이동의 감지는 출/입 행동의 감지에 기초하며 이와 같은 출/입 행동 감지는 2개의 PIR 센서의 감지 순서에 기초하여 이루어진다. 전체 센서 네트워크의 구성은 각 센서노드가 수신 노드와 과 1대1로 연결되는 별 형태로 이루어져 있다. 제안된 시스템은 본보기주택에 설치되어 3명의 사용자를 대상으로 실험되었고, 그 결과 완벽한 출/입 행동 감지와 평균 81.3%의 구성원 식별성능을 얻었다. The tracking of current location of residents is an essential requirement for contextaware service of smart houses. This paper presents a wireless sensor network system which could detect location transition such as entrance and exit to a room and also identify the user who passed the room, without duty of wearing any sort of tag. We designed new sensor node to solve the problem of short operation lifetime of previous work[1] which has two pyroelectric infrared (PIR) sensors and an ultrasonic sensor, as well as a 2.4 ㎓ radio frequency wireless transceiver. The proposed user identification method is to discriminate a person based on his/her height by using an ultrasonic sensor. The detection idea of entering/exiting behavior is based on order of triggering of two PIR sensors. The topology of the developed wireless sensor network system is simple star structure in which each sensor node is connected to one sink node directly. We evaluated the proposed sensing system with a set of experiments for three subjects in a model house. The experimental result shows that the averaged recognition rate of user identification is 81.3% for three persons, and perfect entering/exiting behavior detection performance.

Purpose: Cochlear Implant technique helps hearing impaired children to perceive and produce speech and to develop early reading skills. But children with cochlear implant still have problems in reading comprehension. This study aims at investigating the reason why children with cochlear implant have trouble understanding what they read., examining the use of morphosyntactic strategy, especially postpositional particle strategy which has important role in Korea sentence. Methods: The study has collected 6 children with cochlear implant and 13 normal hearing children who attend elementary schools in Seoul or Gyeonggi-do. Their chronological age had no statistically significant difference. Reading comprehension strategy questions were used to understand the children’s reading comprehension strategy. The questions were made by the researcher and had four items which were semantically or morphosyntactically manipulated to fill in a blank in a 3 to 4 words–long sentence. The children was told the test was under time limit but there was no actual time limit. Results: In reading comprehension strategy task, there was significant difference of correct answers and ratio of error type. Conclusions: Children with cochlear implant do not fully understand the relation between verb and postpositional particle or among postpositional particles. That is, children with cochlear implant pay less attention to morphosyntactic clue than normal hearing children do.
24시간 주기의 독거노인 생활 패턴 모델링 및 이상 검출 방법
이선우(Seon-Woo Lee) 한국정보과학회 2011 정보과학회 컴퓨팅의 실제 논문지 Vol.17 No.7
본 논문에서는 독거노인의 주택에 설치된 원격 모니터링 시스템이 감지하는 센서 데이터를 이용하여 일상 활동을 인식하고, 이 정보에 기초하여 일상 활동의 반복성을 반영하는 24시간 주기의 모델을 만드는 방법과 이 모델에 기초하여 이상(anomaly)을 검출하는 방법을 제안한다. 제안하는 방법은 독거노인의 일상생활 패턴을 구성하는 특징성분(각 방에서의 체류, 외출, 수면 등)의 시간 반복성을 반영하는 퍼지집합으로 생활 패턴을 모델링한다. 이와 함께 구축된 생활 패턴 모델을 이용하여 특정 하루의 일상 활동이 평상시와 얼마나 다른지를 나타내는 척도-이를 이상정도(degree of anomaly)라 함-를 정의하고 이값을 계산하는 방법도 제안한다. 제안한 방법의 유용성을 검증하기 위해 3명 독거노인의 실제 주택에 원격 모니터링 시스템을 설치하고 3개월 이상 운영 실험을 수행하였고, 수집된 데이터를 이용하여 제안된 방법의 특성 분석을 수행하였다. This paper proposes a circadian life pattern model and anomaly detection method for the elderly living alone by using a remote monitoring system. The proposed circadian model is composed of a set of fuzzy sets from time information of features such as staying of each room, going-out event, sleep behavior. The feature can be considered as components of daily living pattern of a resident. The fuzzy sets represent a statistical repetition of the components. Based on the derived life pattern model we propose a measure called the degree of anomaly that can indicate behavioral deviations from usual habits. In order to verify the proposed method, we installed the remote monitoring system into three houses and collected data during over three months, then analyzed the performance of the proposed method.
