This paper deals with the development of a shape inspection system of the Light Guide Panel(LGP), and the study for the performance of the system. The conventional contact sensing methods have been used to inspect the shape. However the contact-sensing methods have some problems. The contact between a tip of the sensor and the surface of objects make a sensor tip abraded and generate a defect on the surface of objects. In this paper, we employed the Non-Contact Optical Sensor[1] to measure the shape inspection system of LGPs, The Sensor composed of Hologram laser[3] unit used for CD Optical Pickup[2] is low cost and has a good performance to measure a transparent objects. From the results of experiments for LGP shape inspection ...

Purpose: This study was done to analyze and clarify the concept of empathy in nursing. Methods: Using the concept analysis framework of Walker & Avant 68 articles about empathy were selected for this study. Results: Defining attributes of empathy included recognizing others' perspective and thought, understanding others' emotion, and communicating with them. The antecedents of empathy included contact with patients, respect and trust for patients, a certain level of cognitive ability, and communication skills. Consequences of empathy were increasing patient self-understanding, self-awareness as a therapeutic subject and improving quality of nursing. The concept was clarified through presentation of model, borderline, related, and contrary cases. Conclusion: The results of this study are meaningful in that the concept and attributes of empathy are explored in the area of nursing. Also, based on results of this study, development of standardized tools to measure patient-perceived empathy and measure the three attributes of empathy is recommended as well as the development of educational programs to enhance empathy.

As various mobile robots and manipulator robots have been commercialized, robots that can be used by individuals in their daily life have begun to appear. With the development of robots that support daily life, the interaction between robots and humans is becoming more important. Manipulator robots that support daily life must perform tasks such as pressing buttons or picking up objects safely. In many cases, this requires expensive multi-axis force/torque sensors to measure the interaction. In this study, we introduce a low-cost two-axis pressure sensor that can be applied to manipulators for education or research. The proposed system used three force sensitive resistor (FSR) sensors and the structure was fabricated by 3D printing. An experimental device using a load cell was constructed to measure the biaxial pressure. The manufactured prototype was able to distinguish the +-x-axis and the +-y-axis pressures.

Since its introduction in 1995 by Schena et al. cDNA microarrays have been established as a potential tool for high-throughput analysis which allows the global monitoring of expression levels for thousands of genes simultaneously. One of the characteristics of the cDNA microarray data is that there is inherent noise even after the removal of systematic effects in the experiment. Therefore, replication is crucial to the microarray experiment. The assessment of reproducibility among replicates, however, has drawn little attention. Reproducibility may be assessed with several different endpoints along the process of data reduction of the microarray data. We define the reproducibility to be the degree with which replicate arrays duplicate each other. The aim of this note is to develop a novel measure of reproducibility among replicates in the cDNA microarray experiment based on the unprocessed data. Suppose we have p genes and n replicates in a microarray experiment. We first develop a measure of reproducibility between two replicates and generalize this concept for a measure of reproducibility of one replicate against the remaining n-1 replicates. We used the rank of the outcome variable and employed the concept of a measure of tracking in the blood pressure literature. We applied the reproducibility measure to two sets of microarray experiments in which one experiment was performed in a more homogeneous environment, resulting in validation of this novel method. The operational interpretation of this measure is clearer than Pearson's correlation coefficient which might be used as a crude measure of reproducibility of two replicates.

이메일은 누구나 쉽게 정보를 교환할 수 있는 편리함 때문에 인터넷에서 가장 중요한 수단으로 사용되고 있다. 그러나 순수한 의사소통의 수단이 아닌 스팸메일의 범람은 성인뿐만 아니라, 어린이 청소년에게도 무차별적으로 전송됨으로써 심각한 부작용을 낳고 있다. 본 논문은 점차 지능화 되는 신 유형의 음란 스팸메일로부터 청소년을 보호하기 위하여 새로운 방법의 음란메일 차단시스템을 제안하고자 한다. 기존의 스팸메일 차단시스템은 사용자가 직접 음란한 메일이라고 판단되는 메일에 대해 일일이 키워드를 설정하거나, 메일 내용 중에 텍스트만을 추출하여 패턴 매칭방법으로 분류하는 것이 대부분이었지만, 본 논문은 기존 방법의 문제점을 해결하기 위하여 이미지 내 Skin-Color분포의 Human Detection 알고리즘과 웹 로봇 에이전트의 하이퍼링크 분석기법을 사용하였다. 성능 측정결과, 형태소 분석과 Human Detection 알고리즘을 병합하여 적용한 경우 성능 측정에서 90% 정도의 F-measure를 보였지만, 추가적으로 웹 로봇 에이전트의 하이퍼링크 분석기법을 병합하여 적용한 경우 97% 이상의 F-measure를 보이며, 신뢰성이 높은 음란스팸메일 차단 시스템을 구현할 수 있다는 것을 증명하였다.

Purpose: Lack of a valid prognosis of gross motor development in children with cerebral palsy (CP) and the absence of longitudinal data on which to base an opinion in Korea have made it difficult to plan treatment and counsel prognosis issues accurately. The purposes of this study were to examine whether the Gross Motor Function Classification System (GMFCS) is valuable to prognostication about gross motor progress in children with CP in Korea. Methods: Medical records of 61 patients were retrospectively reviewed that visited outpatient department and were diagnosed as CP. Various information was surveyed including CP type, visual acuity, cognitive function, motor acquisition age, ambulatory status, development curves of Gross Motor Function Measure (GMFM) according to each of the 5 level of GMFCS. All of them were compared with other studies. Also the gross motor development curves and the maximum GMFM score derived from this study were compared with the Palisano's report and the Rosenbaum's report. Results: Based on a total of 494 GMFM assessments provided by this study, the 5 distinct motor development curves and the maximum GMFM score were created. These observations is corresponding with the Palisano's and the Rosenbaum`s Development curves. Conclusion: The 5 distinct motor development curves (GMFCS) that were created by Palisano's and Rosenbaum's study is useful in Korea, providing parents and clinicians with a means to plan interventions and to judge progress over time.
