La desigualdad social en una comunidad prehispánica de la sabana de Bogotá: el caso de Nueva Esperanza
Authors: Lizcano Leonardo
Published: August 2023

La desigualdad actualmente determina el acceso de las personas a los recursos básicos y a las condiciones generales de vida; sin embargo, vale la pena preguntarse si en las sociedades antiguas dicha condición existió, si fue determinante o si tuvo el mismo impacto que hoy genera. En ese sentido, la arqueología goza de un marco temporal único en el cual es posible vislumbrar un amplio panorama de respuestas para estas preguntas. Por ello, esta obra explora la naturaleza, el grado y la incidencia de las relaciones desiguales en las trasformaciones políticas en el sitio arqueológico de Nueva Esperanza, considerado hasta el momento como la excavación arqueológica más grande de los Andes orientales. Se desarrolla una interpretación sobre los objetos en contextos domésticos para dar cuenta de lo que supone identificar y discutir la existencia de la desigualdad en las sociedades prehispánicas, al tiempo que se cuestiona la relación que presentan los esquemas sociales modernos entre los altos grados de desigualdad y organizaciones políticas complejas.

Published: August 2023

This research aims to measure the impact of the business environment and tax incentives on new investments in Kosovo. A questionnaire created especially for this study was submitted to 104 companies that have invested in Kosovo during the period 2018–2020. It is designed to be as comprehensible and accessible as possible and is divided into an introduction that provides demographic data of the respondent, and types of surveyed businesses, to go through the questions related to new investments, and business environment, and the last section contains questions related to tax incentives. The reliability of the questionnaire is measured by Cronbach’s alpha. In terms of the methodology, a multifactorial regression model and correlation analysis are employed. Based on the multiple regression model, the research results show that the independent variables, such as business environment and tax incentives, have a significant positive impact on the dependent variable, new investments. Furthermore, the correlation analysis between new investments and tax incentives also indicates a strong positive relationship. Additionally, the business environment and tax incentives are the main factors attracting new investments. The results of this study can help to enhance the business climate and boost tax incentives, demonstrating Kosovo’s suitability as a location for new investments. There remains the duty of the government and policymakers to create mechanisms that ensure sustainable business conditions and applicable tax incentives.

Authors: Fu Jie , Zhang Ying , Feng Shaowei , Guo Yongchang , Genevois Cécile , Veron Emmanuel , Yang Yafeng , Wang Hui , Allix Mathieu , Li Jianqiang
Published: August 2023

Transparent Ce:Lu3Al5O12 (Ce:LuAG) phosphor ceramics are promising for
high-power white lighting due to their high quantum efficiency, thermal
stability and low thermal quenching. However, the shortage of red
spectral composition and expensive price are preventing the application
of Ce:LuAG phosphor ceramics in high-quality white lighting. In this
work, (Lu,Gd)3Al5O12-Al2O3 (LuGAG-Al2O3) nanoceramics were prepared by
partially replacing Lu3+ with Gd3+ through glass crystallization. These
ceramics exhibit outstanding transparency and excellent mechanical
properties. Compared with Ce:LuAG-Al2O3 transparent nanoceramics, the
emission spectrum of transparent Ce:LuGAG-Al2O3 nanoceramics shows a
substantial red shift (505 nm→570 nm), which effectively supplement the
red light lacking in Ce:LuAG ceramics. With a maximum quantum efficiency
of 81.4% and excellent thermal stability (87.6% @423 K), these
nanoceramics have potential for high-power white lighting. When used in
high-power LED and LD lighting, Ce:LuGAG-Al2O3 transparent nanoceramics
achieve continuous adjustable changes from green light to orange-yellow
light, and furthermore provide high quality warm white lighting with low
color temperature, high color rendering index, and excellent luminous
efficiency. Combining the facile and moderate elaboration process
through full glass crystallization, the transparent Ce:LuGAG-Al2O3
nanoceramics reported in this paper are therefore regarded as promising
color converters candidates for high-power warm white LED/LD lighting.

Authors: Kipchumba Bett , Chemweno Peter , Nganyi Eric , Ochola Jerry
Published: August 2023

Validating maintenance strategies is crucial for industrial equipment
reliability. Regression analysis establishes correlations between plans
and Mean Time Between Failures (MTBF). This study validates maintenance
schedules and parameters for critical equipment in a textile factory
using regression analysis of system data and maintenance intervals.
Employing the Monte Carlo Simulation technique, it analyzes
relationships between input variables (maintenance activities, equipment
age, operating conditions) and MTBF. An R-squared value of over 0.70
confirms the significance of the regression model. Survey design
identifies critical departments, and real-time equipment failure data
supports the methodology. Regression analysis yields a significant model
(R-squared = 85.56%) with 18 input variables contributing to MTBF
variance. Sensitivity analysis reveals their hierarchical impact.
Conclusions emphasize regression analysis’s efficacy in validating
maintenance strategies, showcasing the input variables’ significance.
Findings underscore tailored maintenance plans and suggest predictive
analytics expansion. Recommendations include adaptive strategies,
predictive analytics integration, optimal maintenance intervals
determination, cost-benefit analyses, and spare parts inventory
optimization.
Optimization of Maintenance Schedule and Parameters for Critical Equipment in a Textile Mill through Statistical Synthesis of System Data and Time Between Maintenance Operations
Authors: Kipchumba Bett , Chemweno Peter , Nganyi Eric , Ochola Jerry
Published: August 2023

Unexpected equipment failure in machines interrupts production schedules
and creates costly downtime. Therefore, the importance of timely
equipment maintenance is to extend the machine lifespan, prevent
unplanned downtime, and reduce the need to buy equipment. Textile
factories tend to have overcapacity of looms with inconsistent
maintenance time schedules. The main objective of the research was to
establish a suitable maintenance schedule time and parameters by
assessing the state of maintenance practices of the critical equipment
in the weaving section. The maintenance time schedules of rapier, and
air-jet looms were studied. Weibull distribution, and Monte Carlo
simulation were undertaken followed by regression analysis of the data.
The setup of the Monte Carlo simulation entailed 1000 instances of the
random values from the systems in the critical equipment. The data were
optimized through Monte Carlos regression modeling and Weibull
distribution analysis to get shape parameter and the scale parameter of
1.47 and 1683.46 hours. In conclusion, the findings indicated that
weaving looms were the critical equipment. The model’s shape parameter
of 1.47 described a steady increase in the risk of wear-out failure
during the early life of the machines. Also, the value of the shape
parameter suggested early wear-out failure and premature failures after
installation. The optimal time interval for maintenance operations was
1683.46 hours from the scale parameter. The findings indicated that
looms had an inconsistent and incoherent maintenance time scheduling
approach. According to the results, it is recommended that preventive
maintenance schedules be done once every 1683.46 hours.

Published: August 2023

IFR forecasts and the conducted literature analysis prove that part of
the research should be focused on adapting the companion robot to moving
around in open space in external conditions. There is a visible interest
in the use of robotic devices in the care and assistance of the elderly
or disabled people. However, the external environment still contains
many obstacles and barriers. According to the authors, the solution to
some of the problems related to movement in outdoor conditions would be
to communicate the companion robot with the road infrastructure, inter
alia, via IoRT (Internet of Robotic Things). This is why the purpose of
this article is to present the concept of communication of the companion
robot with the road infrastructure.

A Case Study on the Development of Curriculum Standards for Liberal Arts Courses for Enhancing Core Competencies at University C
Authors:   Research Institute of Science Education, Kim PilSeong
Published: August 2023

Based on the recently discussed cases of 'OECD Education 2030' and the Minerva School, this study tried to examine the development of core competency-based curriculum standards for liberal arts subjects. University C was based on the concept of competency of the 'OECD Education 2030' project followed by the DeSeCo project to develop curriculum standards and the case of Minerva School. These mainly show how the content and competency of subjects are linked and that the competency encompasses knowledge, skills, values and attitudes, and that competency education is mediated through the educational content. Based on this point, University C developed the curriculum standards for liberal arts subjects to enhance core competencies and designed classes for compulsory liberal arts subjects according to these standards.
In this curriculum standard, learning outcomes are first derived based on the nature of the subject, and educational goals are developed that link these to core competencies and include rubrics for each learning outcome. Then, we are preparing a learning framework that meets these educational goals, standards for educational content centered on core concepts, and strategies for operating curriculum for each subject. This case study presents a method in which core competencies are closely related to the content of the subject, and shows a class framework in which knowledge, skills, values and attitudes are practically integrated away from fragmentary knowledge education, and applied in various situations. It is valuable in that it presents the core concept of the subject with high potential as the most important learning content.
Developing Multicultural Art Education Curriculum for Teaching Non-Art Major Students
Authors:   Research Institute of Science Education, Chang Yong-Sock
Published: August 2023

South Korea is becoming more of a multicultural society due to the increase of trade, the influx of foreign labourers, the increase of international marriages, and globalization. The term, “multiculturalism” has become a familiar term in South Korean. Multicultural education is promoted by many South Korean scholars and educators as an effective means by which to solve the many issues now occurring from the social, cultural and ethnic diversity in South Korea. My research and approach to the issues of diversity, is relevant to multiculturalism, most of the research focusing on the K-12 levels in education (elementary, middle, and high school). There are few multicultural art education programs for college students or adults in South Korea. The programs in existence are commonly used to introduce foreign cultures by using traditional art making and study, such as mask making, traditional clothing design, and doll making. Multicultural art education could be expanded into higher education curriculum to include university students and continuing education for non-traditional adult students, to cover and realize more fully the goals of multicultural education. The aim of this paper is to introduce multicultural art education lessons implemented by two international art instructors working at a university located in the United States who have implemented their multicultural art education program for more than two years. The art classes in this program are designed for non-art major students and are one of the more popular courses offered at the university.
Even though the lessons in this paper are made for a particular social setting and purpose, by sharing the art lessons taught in the program, I have hope that the South Korean multicultural art education program will expand the scope of their curriculum so the goals of multiculturalism meet the needs of the diversity in the country

Published: August 2023

The purpose of this study is to improve the teaching-learning competency required in the industrial field by identifying the parts where classes using graphic calculators are helpful to students of in-house technical colleges located in the provinces. As a case study, this study was conducted targeting first-year and second-year students attending in-house technical colleges in small and medium-sized cities using TI-Nspire. Most of the students were active and passionate about learning, but they were adult students who had to drop out of school due to difficulties in mathematics or change career paths because of studying mathematics. In addition to taking notes and using a camera while observing the class since March 2017, the researcher collected questionnaires and transcribed data after an interview. In July 2020, additional interviews were conducted with the instructor three times. The case study results are as follows.
First, the participating students were cut off from their math studies for a long time, and most of them were afraid of math and had a low level of math knowledge. Second, nevertheless, most of the study participants showed a very positive reaction to the use of TI-Nspire after the end of the lecture, and it was found that the positive view was somewhat improved in terms of saving time and obtaining accurate information when dealing with math problems. Third, it was found that cooperative classes using technology help to deal with mathematical concepts along with self-reflection. Participating students were given the opportunity to learn from each other through cooperative learning in the industrial field by pressing function keys while handling the graphic calculator and re-recognizing the calculation process.

Authors:   Research Institute of Science Education, Lee Jungwoo
Published: August 2023

This study examines the development direction and characteristics of the 2015 revised curriculum 'Inquiry on Social Issues', the development direction and issues in the development process of the 2022 revised curriculum 'Inquiry on Social Issues'. The characteristics of 'Inquiry on Social Issues' were examined based on my experiences of participation in curriculum revision. The 2015 Revised Curriculum 'Inquiry on Social Issues' was newly established as a elective courses for career education in the field of social studies. It is designed to cultivate the ability to select a problem, identify the cause of the problem, and derive a solution. The 2022 revised curriculum, 'Inquiry on Social Issues' was also revised in consideration of the direction of revision pursued in the ‘chongron’ while maintaining the purpose of the 2015 revised curriculum. In addition, the level of difficulty was lowered by reflecting the review opinions raised during the revision process, and modifications were made to allow a more specific approach to social issues. In other words, while maintaining the existing subject goal of 'cultivating learner-initiated social problem-solving ability based on theoretical understanding of social problems', the number of areas and achievement standards was drastically reduced, and they were changed in consideration of the transition to a high school credit system and changes in the type of elective courses. In addition, the contents were more easily modified than the 2015 revised curriculum, the method of presenting social problems was adjusted, and as an elective courses for convergence, it was guided to approach social issues in an integrated manner. In accordance with the purpose of the curriculum revision, the tasks to make 'Inquiry on Social Issues' well used in the classroom was proposed by dividing it into textbook development and class execution.
A Study on Analysis of Research Trends related to International Experiential Learning for Youth in Korea(2015-2022) through Network Text Analysis
Authors:   Research Institute of Science Education, Kim YoungHwan , Lee Chae Young
Published: August 2023

This study aims to analyze trends in domestic research on international experiential learning targeting youth since 2015, to find out tasks and future directions. For the research trend analysis, 127 papers were selected from KISS using keywords related to ‘area’, ‘type’, ‘scope’. The papers were analyzed utilizing Network Text Analysis. The results were as follows. First, the number of publications, while having shown a significant decrease since 2015, started to increase in 2017. Second, a great number of studies was published by international education-related academies. Third, while ‘overseas volunteer’ was the most prevalent research subject, ‘secondary education’ was the least popular one. Fourth, the cluster analysis result revealed a strong connection between ‘2019’ and ‘overseas volunteer', which the policy ‘Job creation through overseas volunteer’, undertaken since 2018, seemed to have an impact. Fifth, ‘online exchange' shows a low value both in frequency and centrality degree. The implications were as follow. First, since the research about ‘secondary education’ has small numbers, more research needs to be conducted. Second, regarding ‘overseas volunteer’ commonly used for personal interest like ‘building up employment qualification’, further discussions on the purpose and meaning of it are required. Third, more research on ICT-based and ICT blended-related are needed. Lastly, the number of researchers who has continuously studied on ‘international experiential learning’ for youth is not enough regarding that the frequency and keywords of studies have been easily affected by policies and social phenomena. Therefore, constant effort by researchers seems to be needed.

Authors:   Institut Pendidikan Indonesia, Muthmainnah Rifaatul
Published: August 2023

There is a need to prepare college students with non-cognitive or 21st Century skills to prepare them for successful college and future careers. As the number of applied STEM in Indonesian education increases, research is needed to understand how STEM learning projects promote student 21st Century skills. This study used a case study and mixed-methods conversion design to convert qualitative data into quantitative data by applying pre-established rubrics. This study provides evidence that STEM learning projects are beneficial to promote students' 21st Century skills, which are: (a) knowledge construction, (b) real-world problem solving, (c) skilled communication, (d) collaboration, and (e) self-regulation. The result shows that students demonstrate the highest grade on collaboration and the lowest on knowledge construction. Although most of the student work introduced multiple 21st Century skills and the overall scores were satisfactory, student knowledge construction still needs improvement.
A project may be more than you think it is
Authors: Triska Ricardo , Ruecker Stanley
Published: August 2023

This paper presents a particular concern about the idea of the Project, namely that its boundaries are fundamentally soft, in addition to being structured around nested processes. The word Project can be understood both in terms of its own definition and with respect to a variety of possible concepts associated with it. The development of a project is a process itself because it usually combines a set of different skills in order to get an appropriate solution for a given demand. Because of the human relevance to the management process, it is a research issue. According to this understanding, project management is presented as "the art of planning, controlling and executing a project in a way that ensures successful delivery of the desired outcome”. At this time another question emerges from the previous discussion: that is, how to do a project? We present the simple answer: Describing the steps on the path to transform an idea into a product is a project itself. It is absolutely expected that each one of the steps described are developed using an understanding of the whole cycle, reinforcing the design approach as non-linear and unpredictable even taken as formal procedures in a product development process.

Um dos sistemas que ajudam a compor esse ambiente midiático é a tipografia, capaz de proporcionar a comunicação além de integrar o fluxo informacional gerando elementos híbridos. Além de modificar a forma como usuários e desenvolvedores interagem a partir dos meios digitais, as inovações tecnológicas têm provocado transformações no âmbito do design e nos processos projetuais da área. A tipografia, campo de estudo que embasa a prática do design, também é influenciada por essas transformações, pelos novos suportes informacionais e pela informatização da produção dos tipos. Neste sentido, novos arquivos de fontes têm sido lançados a fim de possibilitar melhorias direcionadas aos meios digitais. Com este propósito que as fontes variáveis foram anunciadas em 2016 apresentando maior flexibilidade e aproveitamento dos tipos em meios digitais. Este formato de fonte permite que diferentes larguras, pesos, inclinações e outras variações sejam incorporadas em um único arquivo proporcionando ao usuário final a decisão de qual combinação será utilizada. Diante disso, este estudo teve como objetivo identificar indicativos e componentes do processo de design de fontes variáveis a partir da prática profissional de designers de tipos e especialistas em fontes variáveis no desenvolvimento destas. Para tanto, foram realizadas entrevistas com este público. Os dados coletados foram tratados a partir do método de análise de conteúdo e a técnica de análise categorial (BARDIN, 2016), com o auxílio do software ATLAS.ti para análise dos dados qualitativos. Os resultados da pesquisa permitiram indicar os cinco principais componentes do processo de design de fontes variáveis, a saber, testes, espaço de design, presença de agentes externos ao designer de tipos, contexto de uso e orientação para o desenho dos caracteres, demarcando sua relação com as tecnologias digitais.
Physical and Mechanical Properties of Paper Packaging in the Food Industry
Authors: GÜCÜŞ Mehmet Onurhan
Published: August 2023

Consumers are constantly concerned about the safety of foods containing synthetic preservatives as well as the increasing number of diseases caused by pathogenic and spoilage microorganisms in food nowadays. The hydrophilicity and porous nature of the paper can easily cause the adsorption of water from the environment or food and become a suitable medium for the growth of microorganisms. The main problem with food wrapping paper and cardboard is that their basic properties are not fully understood. Packaging materials that come into contact with food, whose basic properties are determined by paper and cardboard tests, can be used appropriately instead of end-use. Hence, by reducing the risk of pathogens, it can contribute to the existing studies that are researched to prevent the proliferation of microorganisms. These preliminary tests are critical for active packaging, where antimicrobial agents are incorporated into the packaging material, which forms a protective layer through the vapor phase or direct contact with food. Thus, the main resource will be provided for antimicrobial packaging coated with essential oils, antimicrobial packaging with enzymes, antimicrobial packaging with bacteriocin, and antimicrobial packaging with inorganic materials. In this study, basic tests on three food contact paper samples were performed, and the results were compared. According to these results, better burst resistance and tensile strength results are seen in cardboard packaging. On the contrary, index values decreased when compared to the other paper samples. In the water resistance test, the best results were obtained on wrapping papers. Sulphite paper was the paper type with the none of highest resistance, according to the test results. In this rapidly developing technology, it is foreseen that naturally produced or naturally produced biopolymers will not play an important role in reducing environmental waste by combining them with packaging.

PT.PTM as one of major oil and gas company in Indonesia contributes highly to fulfilling oil and gas demand in Indonesia. However, with more than 40 years of operation, PT. PTM is currently at its declining phase. Aggressive development projects have been planned to sustain PT. PTM production. The latest development project is M-X new field developments.
This Final Project is intended to assess the M-X Project feasibility in terms of economic terms considering possible dynamic changes in several factors. The results of this final project will help PT.PTM management decide whether to invest in the development of the M-X field. Both Discounted and Non-Discounted Cash Flow (DCF and Non DCF) will be used in the M-X Project investment analysis. Revenue and cost breakdown will follow Production Sharing Contract (PSC) – Cost Recovery scheme as applied for PT. PTM. The Non-DCF analysis shows that 264.65 MMUSD net cash flow will be generated for the Government due to M-X development while PT. PTM will gain 49.97 MMUSD with payback period of 3 years after M-X production. DCF analysis result shows that Project Net Present Value (NPV) is 4.35 MMUSD with an IRR of 12%. Financial risk due to dynamic changes in oil and gas project is analyzed using Montecarlo simulation that resulted on 23.3% probability to have negative NPV with Mean NPV of 13.93 MMUSD. The analysis result from Non-DCF and DCF method shows positive result for PT. PTM management to proceed with investment planning for M-X field development.
