  • This research attempted simplifications to the LED street light for price competitiveness. The street light was simplified by replacing the SMPS with an IC driver on the PCB using an AC-type LED. The optical element that shape of a line-shaped lens covered LED crowded. Thus, this study aims to improve LED efficiency by using the minimum optical system. In order to satisfy the M3 regulation of street lighting at grade, the lens was divided into two parts depending on the forward direction of the light. Further, the changes in the number of LEDs located on part 1 and part 2 of the lens were analyzed. Through simulation, we determined the proper light distribution that meets M3 regulation of street lighting.

  • ASEAN Economic Community (AEC) was established in 2015 from 10 countries to realize the ultimate (adopted in 1997), which aimed to transform ASEAN into a stable, prosperous, and highly competitive region with equitable economic development, reduced poverty, and socioeconomic disparities. The purpose of this paper is to examine the effect of knowledge level on the AEC of Vietnamese small and medium enterprises (SMEs) in the textile and apparel industry towards attitudes, readiness, and performance. This study uses convenience sampling to get questionnaires from 150 SMEs in Hanoi, Vietnam. Then, the paper applies SPSS-AMOS 24 to process data. The empirical results show that AEC's implementation only has a small impact on improving SME performance. However, SMEs have adequate knowledge, attitude, and readiness about AEC. The structural modeling findings indicate that the knowledge factor has an indirect effect on SMEs' performance. This finding is to provide new insight into the roles of attitude and readiness in the case of Vietnam. These factors are needed to mediate the effect of attitudes and readiness in the relationship between knowledge and business performance, a framework strategy of business organizations, and can be used as a conceptual model to improve SMEs' performance.

  • The essay discusses the way in which the aesthetic of Pre-Raphaelites reformulates the habitual system of knowledge in the Victorian age by adapting $Ranci{\acute{e}}re^{\prime}s$ concept of aesthetics. $Ranci{\acute{e}}re$ develops an original theory of aesthetics, a regime of knowledge which enables to perceive and reflect art as such. In this way, aesthetics turns to be the logical system by which the consensus idea of the beautiful comes to exist. For $Ranci{\acute{e}}re$, aesthetics is an agreed system of the sensible and reproduces the habitual knowledge of the world. Therefore, a new aesthetic movement means an attempt to break the given aesthetics and reorients the new distribution of the sensible. The important point of $Ranci{\acute{e}}re^{\prime}s$ argument is that he does not presuppose the dimension beyond the present unlike Frankfurt School. What $Ranci{\acute{e}}re$ claims is that there is no such the aesthetic which can correct the instrumental reason, but rather an indifferent moment in which a worker finds out himself as a creator who can give rise to the new regime of the sensible and feels free from what he must work for. From this perspective, the essay explores the aesthetic of Pre-Raphaelites and its meaning in nineteenth century Britain. Pre-Raphaelites was an artist group who railed against a so-called academic style of paintings and created a new aesthetic criterion to describe the truth of the natural world. The essay examines the interrelationship between Pre-Raphaelites and photography that would enable them to re-distribute the sensible and produce a new way of seeing the order of things. This is related to the birth of a modern gaze as in the case of landscape paintings. What is crucial is that the distribution of the sensible is always-already doubled with the political. In short, Pre-Raphaeltes is not only an aesthetic movement but also a political pursuit to achieve a disenchanted perception of nineteenth century industrial capitalism.

  • 전체 결과의 80%가 전체 원인의 20%에 의해 일어난다는 파레토 법칙(Pareto principle)은 상위 20%의 핵심 고객에 대한 우선적인 마케팅을 비롯하여 기업 경영의 많은 부분에서 적용되어 왔다. 파레토 법칙과는 대조적으로, 80%의 사소한 다수가 20%의 핵심적인 소수보다 우월한 가치를 창출한다는 롱테일 법칙(Long Tail theory)은 ICT(Information and Communication Technology)의 발전과 함께 새로운 경영 패러다임으로 주목 받아오고 있다. 본 연구의 목적은 경영 현장에서 양대 흐름을 형성해온 이러한 법칙들이 변화무쌍한 글로벌 가상화 환경에서 기업의 핵심적인 성공 요인이라고 할 수 있는 가상 지식 협업에는 어떻게 관련되는지를 규명하는 것이다. 이를 위해, 대표적인 가상 지식 협업 커뮤니티인 위키피디아에서 품질 최상위 등급인 피쳐드 아티클(Featured Article) 레벨로 승급된 2,978개의 아티클에 대한 협업 행위를 분석하였다. 즉, 각 아티클 그룹에서 편집 횟수 기준 상위 20%에 속하는 참여자들의 총 편집 횟수가 전체 편집 횟수에서 차지하는 비율인 파레토 비율(Pareto ratio)이 지식 협업 효율성과 어떤 관계를 가지고 있는지를 도출하였다. 그리고, 이러한 연구를 편집 참여를 통한 지식 공유에 대한 전체적인 불평등 정도를 나타내는 지니 계수(Gini coefficient)의 영향 및 그룹의 작업 특성을 반영하도록 확장하였다. 결과적으로, 지식 공유의 파레토 비율과 지니 계수가 증가하면 지식 협업 효율성도 높아지지만, 이러한 변수들이 일정 수준 이상으로 증가하면 오히려 지식 협업 효율성이 낮아지는 역 U자(inverted U-shaped) 관계가 있음을 확인하였다. 그리고, 이러한 관계는 인지적 노력을 상대적으로 더 많이 요구하는 학문적인 특성의 작업에서 더 민감하게 작용하는 것으로 보인다.

  • The inverse Rayleigh model distribution and Rayleigh distribution model were widely used in the field of reliability station. In this paper applied using the finite failure NHPP models in order to growth model. In other words, a large change in the course of the software is modified, and the occurrence of defects is almost inevitable reality. Finite failure NHPP software reliability models can have, in the literature, exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, proposes the inverse Rayleigh and Rayleigh software reliability growth model, which made out efficiency application for software reliability. Algorithm to estimate the parameters used to maximum likelihood estimator and bisection method, model selection based on mean square error (MSE) and coefficient of determination($R^2$), for the sake of efficient model, were employed. In order to insurance for the reliability of data, Laplace trend test was employed. In many aspects, Rayleigh distribution model is more efficient than the reverse-Rayleigh distribution model was proved. From this paper, software developers have to consider the growth model by prior knowledge of the software to identify failure modes which can helped.

  • The main aim of the paper is to assess the level of financial literacy among business students. It further aims to investigate the role of external factors that may determine financial literacy. The external factors considered in this study are gender, grade point average, specialization, financial education, and financial socialization. Standard scales such as the Test of Financial Literacy, the Big Three, and other instruments were adapted to measure Financial Knowledge. Further, the study also explored relationships between several factors and the financial knowledge of students. These factors included a student's gender, specialization, number of finance or related courses studied, current Grade Point Average, and financial socialization. A total number of 303 valid responses were received through an online questionnaire administered to business students studying in a public university in the country. Statistical tests namely independent samples t-Test, one-way ANOVA, and correlation analysis were performed in SPSS 28.0. Results show that the overall financial knowledge of students is above average. Gender, number of finance or related courses, and financial socialization do not exhibit any significant relationship with financial knowledge. Current GPA and specialization show significant relationships. The findings of this study have important sectoral and research implications.

  • The purpose of the research was to investigate the characteristics of technology users, their knowledge about the technology and whether that affected technology adoption, and, through the measurement utilitarian value as a mediator, to find out whether the behavior toward mobile payment technology adoption is considered most effective during the COVID-19 pandemic, especially at this research locus, Central Java Province, Indonesian Batik SME consumers. The research methodology was quantitative with data processing using Structural Equation Modeling (SEM) with the final sample of 294 respondents' answers. To the best of the researcher's knowledge, this was an initial attempt toward a holistic and integrative approach to explain the adoption of mobile payment in Indonesia with different consumer characteristics in each region of Indonesia and varying levels of knowledge about mobile payment applications. The results show that the utilitarian value as a mediating variable only affected the relationship between the characteristics of technology users and adoption behavior. The findings of this study suggest that the stronger the knowledge of technology users, the more influential the adoption behavior of the mobile payment technology for Indonesian Batik small-, and medium-sized enterprise (SME) consumers during the COVID-19 pandemic in the new normal era.
