This paper introduces a resistance scanning-type flexible tactile sensor for intelligent robots and presents the output characteristics of the sensor via signal processing. The sensor was produced via the lamination method using multi-walled carbon nanotubes (a conductive material), an insulator, and Tango-plus (an elastic material). Analog and digital signal processing boards were produced to analyze the output signal of the sensor. The analog signal processing board was made up of an integrator and an amplifier for signal stability, and the digital signal processing board was made up of an IIR filter for noise removal. Finally, the sensor output for the contact force was confirmed through experiments.

본 연구의 목적은 집단미술치료를 고등학교 야구선수들에게 적용하고 자기효능감 및 운동스트레스에 미치는 효과를 검증하는 것이다. 이러한 연구목적을 이루기 위해 U시에 소재한 고등학교 야구선수 20명을 실험집단 10명, 통제집단 10명으로 구성하였다. 실험집단을 대상으로 집단미술치료를 주1회 3시간씩 12회기 실시하였다. 측정도구는 자기효능감과 운동스트레스이며 사전, 사후, 추후 점수에 대해 반복측정에 의한 분산분석(Repeated Measures ANOVA)을 실시하였다. 주요 연구결과를 정리하면 다음과 같다. 첫째, 집단미술치료는 고등학교 야구선수의 자기효능감 전체와 그 하위요인인 자기조절효능감과 과제난이도 선호에서는 긍정적 효과가 있음을 확인할 수 있었으나, 자신감에서는 유의미한 효과가 나타나지 않았다. 둘째, 집단미술치료는 고등학교 야구선수의 운동스트레스 감소에 긍정적인 효과가 있음을 확인할 수 있었다. The purpose of this study was to apply group art therapy to high school baseball players and verify the effect on self-efficiency and exercise stress. In order to achieve the research purpose, 20 high school baseball players based in U city were divided into 10 experimental groups and 10 control groups. The experiment group consisted of 12 consecutive group art therapy sessions per weekly for 3 hours each. The measurement tools were self-efficiency and exercise stress, and the repeated measurements ANOVA was performed on the pre-, post-, and later scores. The main results of the study are summarized as follows: First, group art therapy had a positive effect on self-efficiency of high school baseball players and their sub-factors - self-regulating efficiency and task difficulty preference - but did not show significant effect in self-confidence. Second, group art therapy had a positive effect on reducing exercise stress in high school baseball players.

본 연구의 목적은 공감중심의 집단미술치료 프로그램을 대학생에게 적용하고, 의사소통 및 인간관계 능력에 미치는 영향을 검증하는 것이다. 연구목적을 달성하기 위하여 경기지역 대학생 26명을 무작위로 실험집단 11명과 통제집단 15명으로 구성하였다. 실험집단을 대상으로 공감중심 집단미술치료를 주1회 2시간씩 10회기 실시하였다. 측정도구는 의사소통 능력 척도(PCI, Primary Communication Inventory)와 인간관계 척도(RCS, Relationship Change Scale)이며 사전, 사후 점수에 대해 공분산분석(ANCOVA)을 실시하였다. 주요 연구 결과를 정리하면 다음과 같다. 첫째, 공감중심 집단미술치료 프로그램은 대학생의 의사소통능력 전체와 그 하위요인인 언어적 의사소통능력에 유의미한 효과가 있었으나, 비언어적 의사소통에는 유의미한 효과가 나타나지 않았다. 둘째, 공감중심 집단미술치료 프로그램은 대학생의 인간관계 전체와 그 하위요인의 표현력, 개방성에 있어 유의미한 효과가 있었지만, 만족감, 신뢰감, 친근감, 민감성, 이해성에서는 유의미한 효과가 나타나지 않았다. The purpose of this study was to apply empathy - centered group art therapy programs for college students and verify their effects on communication skills and interpersonal relationships. For the research 26 college students in Gyeonggi Province were randomly divided into 11 experimental groups and 15 control groups. The experimental group underwent 10 consecutive group art therapy sessions per week for 2 hours each. The measurement tools included Primary Communication Inventory (PCI), Relationship Change Scale (RCS), and covariance analysis (ANCOVA) on the pre and post scores. Results demonstrated that empathic group art therapy program had a considerable effect on college students’ verbal communication skills but did not show any major effect on the non-verbal communication skills of sub-factors. Furthermore, the empathic group art therapy program had a significant effect on the total value of interpersonal relationships, including the sub-factors of expressiveness and openness but it did not indicate any consequential effect on satisfaction, trust, affection, sensitivity and understanding.
치과용 임시수복재 타입에 따른 색안정성,광택도, 기계적 및 물리적 특성 비교 연구

The objective of this study was to compare the color stability, gloss, mechanical and physical properties of four different types of temporary filling materials. Commercially available hydraulic-setting (HS), powder-liquid (PL), thermoplastic (TP), and light-cured (LC) types of materials were used as experimental groups for each evaluation. To measure the color stability, the amount of color change (Δ *) was calculated based on the color brightness ( ) and saturation ( , ) values using a spectrophotometer after immersion in coffee for 3 days and 7 days. The gloss unit was measured using a gloss meter. In addition, Vickers hardness, Shore hardness, compressive strength, flexural strength, water sorption and solubility, and morphology observation were performed. All experimental groups showed significant color change after immersion in coffee (p<0.05). The color stability increased in the following order: HS<PL<TP<LC (p<0.05). In terms of gloss, there was no significant difference between LC and PL, TP and HS after immersion (p>0.05). The Vickers hardness increased in the following order: PL>HS>TP (p<0.05). There was a significant difference in compressive strength in the order of group PL>HS and flexural strength in the order of group TP>LC (p<0.05). The water sorption and solubility increased in the following order: HS>LC>PL>TP (p<0.05). The surface microstructure change did not change prominently before and after immersion, except for HS. The results of this study suggest the criteria for selecting a temporary filling material suitable for each patient’s various oral characteristics according to the patient's aesthetic needs and goals for functional and physical improvement.
