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.

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.

Background: This study was to investigate the effects of coordinative locomotor training(CLT) using elastic bands on pain, dynamic balance, muscle strength, and muscle activity of female college students with patellofemoral pain syndrome(PFPS). Design: Randomized Controlled Trial Methods: Twenty-six female college students with PFPS were assigned randomly to an experimental(n=13) or control(n=13) group. The experimental group performed CLT using an elastic band. The control group performed squat exercises to strengthen muscle strength. The 30-minute intervention was applied a total of twelve times, three times a week for four weeks. All subjects measured the pain, the muscle strength, the dynamic balance, and the muscle activity(VL/VM ratio) before and after intervention. A paired t-test was used for the determination of differences before and after treatment, and an independent t-test was used for the determination of differences between treatment groups. Results: As a result of comparison within groups, the experimental group showed significant differences in pain, muscle strength, dynamic balance, and VL/VM ratio after the experiment(p<0.05), and the control group showed significant differences in pain, muscle strength, and dynamic balance after the experiment(p<0.05). In comparison between the two groups, the experimental group showed more significant differences in pain, dynamic balance, and VL/VM ratio than the control group(p<0.05), and the control group showed more significant differences in muscle strength than the experimental group(p<0.05). Conclusion: Based on these results, CLT using elastic bands effectively improved the pain, muscle strength, dynamic balance, and VL/VM ratio of female college students with PFPS.

충격공진법과 초음파속도법을 통한 콘크리트 압축강도 예측의 신뢰성 평가

Non-destructive testing (NDT) methods are widely used in the construction industry to diagnose the defects/strength of the concrete structure. However, it has been reported that the results obtained from NDT are having low reliability. In order to resolve this issue, four kinds of NDT test (ultrasonic velocity measurements by P-wave and S-wave and the impact resonance methods by longitudinal vibration and deformation vibration) were carried out on 180 concrete cylinders made with two kinds of mix proportions. The reliability of the NDT results was analyzed and compared through the measurement of the actual compressive strength of the concrete cylinders. The statistical analysis of the results was revealed that the ultrasonic velocity method by S-wave is having lowest coefficient of variation and also most capable of stable observation. Analytical equations were established to estimate the compressive strength of the concrete from the obtained NDT results by relating the actual compressive strength. Moreover the equation established by the ultrasonic velocity method by S-wave had the highest coefficient of determination. Further studies on the stability of non-destructive testing depending on various mixing conditions will be necessary in the future. 콘크리트구조물의 진단에 사용되는 비파괴실험법들은 구조물에 손상을 입히지 않고 구조물의 결함이나 강도를 추정할 수 있다는 장점이있지만 추정값에 대한 신뢰성이 떨어진다는 문제점이 있다. 본 연구에서는 이러한 문제점을 해결하기 위해 2가지 배합으로 총 180개의 공시체를 제작하였고, P파와 S파에 의한 초음파속도 측정, 종진동과 변형진동에 의한 충격공진법 총 4가지의 비파괴실험을 실시하였다. 그리고 실제압축강도 측정을 통해 비파괴실험 결과값의 신뢰성을 비교 분석하였다. 각 비파괴실험법의 결과값에 대한 통계적 분석결과 변동계수값이 가장 낮은 실험법은 S파에 의한 초음파속도법으로 가장 안정적인 관측이 가능한 것으로 나타났다. 한편, 실제압축강도와의 관계를통해 압축강도 4개의 압축강도 추정식을 제안하였으며 S파에 의한 초음파속도법의 결정계수값이 가장 높은 것으로 나타났다. 향후 다양한배합조건에 따른 비파괴실험 신뢰성에 대한 보완 연구가 필요할 것으로 판단된다.

杜亞泉과 陳獨秀 논쟁의 검토

이한결 중국근현대사학회 2022 중국근현대사연구 Vol.96 No.-

This thesis examines the debate between Du yaquan, Editor-in-chief of 『Eastern Miscellany(東方雜誌)』 and Chen duxiu, leading figure in the New Culture Movement-. In Spetember of 1918, Chen raised suspicion and argued through the pages of 『New Youth(新靑年)』, that 『Eastern Miscellany』 is supporting the idea of revival of hereditary monarchy. Du countered this suspicion on 『Eastern Miscellany』 three months later. This exchange of arguments through the pages of their own magazine is often regarded as starting point of ‘East-West (Cultural) Debate’ in later studies. In 1990s’, studies on Du yaquan began, From the early 1910s’, media activities of Du yaquan were mainly focused on political proposals. He was concentrating on how to establish constitutional politics in China. After the establishment of the Republic of China, Du focused on developing discussions on the relationship between individuals, society and state, during this process he often emphasized the importance of Chinnese civilization. On the other hand, one of the main activities of the New Culture Movement was a critique on Chinese civilization, especially Confucianism political ethics. Among them, Chen duxiu was the one who had the most severe criticism on effect of Confucianism ethics in republic of China. Previous studies on this debate, mainly focused on how Du and Chen had differed in understanding of the Chinese civilization. In this thesis, by I pointed out that ‘debate’ between Du and Chen was not a result of their diffenrence in understanding of Chinese civilization, but it was rather Chen portraying Du as a person opposed to republican politics in order to emphasize the discussion he had argued through his journalism activities. In this process, Chen formed his argument by ignoring the context of Du’s media activity. Du was one who constantly supported the idea of settling republican politics in China. But in the debate, Du only pointed out the logical fallacies of Chen. In response to Du’s argument, Chen raised the question again and labelled Du as one who opposed republican politics. Image of Du yaquan, as an opposer of Chen duxiu and New culture movement was maintained for a quite long time.

‘키워드 검색광고(Keyword Search Advertisement)’라 함은 광고주가 인터넷 포털업체로부터 특정 키워드를 구매하거나 이러한 키워드와 관련된 인터넷 공간을 구매하여, 이용자가 해당 키워드를 검색한 경우 검색결과화면에 광고주의 사이트가 표시되거나 광고주를 홍보하는 내용의 배너광고가 게재되도록 하는 온라인 마케팅 기법이다. 최근 인터넷 검색엔진의 사용이 증가함에 따라 이러한 키워드 검색광고 서비스와 관련된 많은 분쟁이 발생하고 있다. 이와 관련하여 ① 상표권자의 상표를 경쟁업체에 검색용어로 판매하는 인터넷 포털업체의 키워드 검색광고 서비스가 상표법상 상표권 침해 등에 해당하는지 여부, ② 상표권자가 인터넷 포털업체에 대해 상표권 침해 기타 법적 책임을 물을 수 있는지 여부, ③ 상표권자가 경쟁업체(광고주)에 대해 상표권 침해 기타 법적 책임을 물을 수 있는지 여부가 문제된다. 키워드 검색광고의 상표권 침해여부는 상표법상 상표의 사용에 해당하는지와 상표권 침해를 구성하기 위한 요소로서 혼동가능성이 존재하는지, 그리고 부정경쟁방지법상 상표 희석화에 해당하는지 여부를 기준으로 판단한다. 이러한 문제의식을 바탕으로 키워드 검색광고의 상표법적 문제 및 관련된 법적 쟁점들에 관하여 검토하고, 상술한 문제점들에 관한 합리적인 해결방안을 생각해 볼 필요가 있다. Internet search engines have become one of the most important tools of the online advertisement. As the internet service is getting developed nowadays, there are many serious cases in which the famous trademark is misused by others without consent from real holders. They are purposing of free-riding on reputation of trademark. By this consequence, its right holder come to loose their customers because of this incorrect search result from their trademarks. This is causing issues on trademark law regarding online advertisement. To judge whether the trademark is infringed is mainly depend on if it is used as a trademark and if it has likelihood of confusion as a factor to constitute trademark infringement, and if infringing a principle of dilution on unfair competition law. Therefore, we will review the problems of each factor related to point at issues above mentioned and it will be focused on legal problem related to keyword search advertisement in trademark law. Then we will discuss the matter of protection schemes in trademark law for famous trademark terms used on keyword search advertisement along with the study over application and solution for infringement of trademark and unfair competition.
