Objectives The purposes of this study were to develop an instrument which measures secondary school students’ attitudes toward Statistics. Methods We analyzed various instruments measuring attitudes toward Statistics, especially SATS-36 and revised SATS-36 suitable for secondary school students in Korea. We revised the questionnaires based on the survey of 301 secondary school students and unified validity theory. Results With conducting exploratory factor analysis, it was found that four factors were appropriate for secondary school students’ attitudes toward Statistics, unlike the results of Schau’s(2003), which was divided into six factors. The four factors are cognitive competence, interest, value, and effort. Especially, cognitive competence, difficulty, and affect factors of the SATS-36 were combined into one factor. The effort factor was shown highest average score and the interest factor was shown lowest average score. Conclusions We developed an instrument appropriate for secondary school students’ attitudes toward Statistics based on SATS-36. With the revised and validated instruments, this study is expected to contributes to researches on secondary students’ attitudes toward Statistics.

The purpose of this study was to determine the effect of water intake and walking exercise for improving life care on blood circulation and stress of Healthy Adults in Their Twenties. The subjects of this research were 10 university students. To achieve this purpose, the blood flow velocity of the vein was measured using a ultrasound system, and the heart rate variability was measured using an electrocardiogram measurement system at before and after interventions. The interventions were conducted under three conditions: Ⅰ- walking with water intake, Ⅱ- walking without water intake, Ⅲ- only rest with water intake. The subjects were measured three times for three weeks on setting a washout period of one week. The conditions were conducted in the order selected by randomization. When participants were walking with water intake for 60 minutes on a treadmill, there were significant differences blood flow rate(p<.05) and stress index of SDNN(p<.05) and heart rate variability(p<.05). But there were no significant differences blood flow rate and stress index when participants were walking without water intake. When participants were conducted in only rest with water intake, there were no significant differences blood flow rate and stress index of SDNN, LF, and HF, whereas there was a significant difference stress index of heart rate variability(p<.05). The results found that walking exercise with water intake had a positive exercise effect of blood flow rate and stress index than walking exercise without water intake or only water intake and rest.

중화민국 초기 입헌정치와 국민심리-杜亞泉의 논의를 중심으로-

이한결 연세사학연구회 2023 學林 Vol.51 No.-

This thesis examines writings of Du Yaquan(杜亞泉), who discussed the problems of China’s bureaucracy after the establishment of the Republic of China. His solution to the problem was to promote National psychology of China. Although the political system of China changed from despotism to republicanism through the Xinhai Revolution, the traditional idea of valuing officials and considering the authority of the government as the highest was still entrenched in Chinese society. The traditonal ideas on bureaucracy did not disappear, which delayed estblishment of new system for republican politics. Du realized the settlement of constitutional politics in China was difficult due to people’s concept of ‘politics’ was not mature. Du had insisted that ‘Reducing politics(減政)’ was necessary to reform Chinese politics even before the Xinhai Revolution. He continued to emphasize its importance even after the establishment of the Republic of China. Du insisted that Chinese people’s psychology should be changed, in order to clear out negative influence of bureaucracy that had been formed along with history. To achieve this goal, he claimed that China needs to establish a new morality, which would change the tendency of Chinese valuing ‘fact’ more than ‘principle’ of things. 이 논문은, 중화민국 수립 직후 중국의 관료정치의 문제점과 이에 대한 해법으로 중국의 국민심리를 진작시킬 것을 논한 杜亞泉의 논설을 분석한 것이다. 신해혁명에 의해 중국의 정체는 전제정치로부터 공화정치로 바뀌었지만, 관리를 중시하고, 관의 권위를 최고의 것으로 여기는 전통적인 관념은 여전히 중국사회에 자리잡고 있었다. 관료정치의 폐해는 사라지지 않았으며, 공화정치를 위한 새로운 제도가 정착하지 못하고 있었다. 특히, 임시대총통인 袁世凱가 헌법에 의거하지 않고 자의적인 명령을 남발하고 있는 상황을 杜亞泉은 크게 우려했다. 공화정이 수립된 후 1년 동안의 추이를 돌아본 杜亞泉은, 입헌정치가 중국에 정착하기 어려운 이유가 ‘정치’에 대한 인민의 관념이 성숙하지 못한 점에 있다고 여겼다. 신해혁명 이전부터 중국의 정치를 개혁하기 위해서는 ‘減政’이 필요하다고 주장해 온 杜亞泉은, 중화민국 성립 이후에도 지속적으로 그 중요성을 강조했다. 杜亞泉은 중국의 역사와 함께 형성되어 온 관료정치의 폐해를 타파하기 위해서는 국민심리를 바꾸어야 한다고 주장했다. 서양문명의 수입에 의해 중국인의 심리는 크게 변화하였는데, 정신문명보다 물질문명을 중시하는 변화가 급속도로 진행되고 있음을 우려했다. 중국의 국민심리가 사물의 ‘원리’보다 ‘사실’을 중시하는 점이라고 본 杜亞泉은, 중국에 새로운 도덕의 정립이 필요하다는 주장을 하기에 이르렀다.

Design of near-unity transmittance dielectric/Ag/ITO electrodes for GaN-based light-emitting diodes

We designed a near-unity transmittance dielectric/Ag/ITO electrode for high-efficiency GaN-based lightemitting diodes by using the scattering matrix method. The transmittance of an ultrathin metal layer, sandwiched between a dielectric layer and an ITO layer, was investigated as a function of the thickness and the optical constant of each constituent layer. Three different metals (Ag, Au, and Al) were examined as the metal layer. The analytical simulation indicated that the transmittance of a dielectric/metal/ITO multilayer film is maximized with an approximately 10-nm-thick Ag layer. Additionally, the transmittance also tends to increase as the refractive index of the upper dielectric layer increases. By tailoring the thickness of the dielectric layer and the ITO layer, the dielectric/Ag/ITO structure yielded a transmittance of 0.97, which surpasses the maximum transmittance (0.91) of a single ITO film. Furthermore, this extraordinary transmittance was present for other visible wavelengths of light, including violet and green colors. A complex phasor diagram model confirmed that the transmittance of the dielectric/metal/ ITO multilayer film is influenced by the interference of reflected partial waves. These numerical findings underpin a rational design principle for metal-based multilayer films that are utilized as transparent electrodes for the development of efficient light-emitting diodes and solar cell devices.

The purpose of this study was to determine the effect of biofeedback pelvic stabilization exercise on pain and static balance for improving life care in non-specific low back pain patients. The subjects of this research were 35 university students. To achieve this purpose, the pain was measured using VAS and KODI, and the static balance was measured using an BSS at before and after interventions. The experimental group performed pelvic stabilization exercise focusing on the gluteus medius muscle using pressure biofeedback equipment, and the control group performed pelvic stabilization exercise without using biofeedback equipment. Both groups performed interventions for 4 weeks, 3 times a week, for 30 minutes. VAS(p<.05) and KODI(p<.05) score of pelvic stabilization exercise experimental group using biofeedback were significantly reduced more than the control group. In static balance, the overall balance index(p<.05), the anterior-posterior balance index(p<.05), and the medial-lateral balance index(p<.05) of pelvic stabilization exercise experimental group using biofeedback were significantly improved than the control group. The results of this study show that pelvic stabilization exercise using pressure biofeedback equipment can have a positive effect on pain and static balance compared to general pelvic stabilization exercise, and can help improve life care for non-specific low back pain patients.
