Background: School-aged children living near plastics–producing factories may have higher risk of exposure to phthalates released during the manufacturing processes. Objectives: We aimed to investigate the urinary concentrations of phthalate metabolites in school-aged children living near a petrochemical complex and estimate the cumulative risk of phthalate exposure. Methods: We used a well-established cohort (Taiwan Petrochemical Complex Cohort for Children, TPE3C) of school-aged children (6–13 years old) living near polyvinyl chloride (PVC) and vinyl chloride monomer (VCM) factories in central Taiwan from October 2013 to September 2014. A total of 257 children were included from five elementary schools: Syu-Cuo Branch (n = 58, school A, ~0.9 km), Feng-An (n = 40, school B, ~2.7 km), Ciao-Tou (n = 58, school C, ~5.5 km), Mai-Liao (n = 37, school D, ~6.9 km), and Lung-Feng (n = 57, school E, ~8.6 km). We analyzed 11 metabolites of seven phthalates (including di-2-ethylhexyl phthalate (DEHP) and di-n-butyl phthalate (DnBP)) in urine. Daily intakes (DIs) were compared with acceptable intake levels to calculate the hazard quotient (HQ) for individual phthalates, and the cumulative risk for each child was assessed using a hazard index (HI), which was the sum of the the individual HQs. Results: The geometric mean and proportion of participants with HIs exceeding one for hepatic (HIhep) and reproductive (HIrep) effects were 0.33 (13.2%) and 0.24 (7.8%), respectively. The major contributors to phthalate exposure risk were DEHP, di-iso-butyl phthalate (DiBP) and DnBP in all children. Moreover, we observed a U shaped distribution of DEHP exposure by school distance from the PVC and VCM factories (school A: 7.48 μg/kg/day and school E: 80.44 μg/kg/day). This may be due to emissions (closest) and and being located downwind of PVC scrap incineration (farthest). Conclusions: Our findings suggest that children living near a petrochemical complex were at a greater risk of phthalate exposure than normal school-aged children and that phthalate exposure was mainly attributed to DEHP, DiBP and DnBP. In addition, inhalation may have been a risk factor for people living near to PVC and VCM factories.

Throughout the cold and the warm periods of 2020, chemical and toxicological characterization of the water-soluble fraction of size segregated particulate matter (PM) (<0.49, 0.49–0.95, 0.95–1.5, 1.5–3.0, 3.0–7.2 and >7.2 μm) was conducted in the urban agglomeration of Thessaloniki, northern Greece. Chemical analysis of the water-soluble PM fraction included water-soluble organic carbon (WSOC), humic-like substances (HULIS), and trace elements (V, Cr, Mn, Fe, Ni, Cu, Zn, As, Cd and Pb). The bulk (sum of all size fractions) concentrations of HULIS were 2.5 ± 0.5 and 1.2 ± 0.3 μg m−3, for the cold and warm sampling periods, respectively with highest values in the <0.49 μm particle size fraction. The total HULIS-C/WSOC ratio ranged from 17 to 26% for all sampling periods, confirming that HULIS are a significant part of WSOC. The most abundant water-soluble metals were Fe, Zn, Cu, and Mn. The oxidative PM activity was measured abiotically using the dithiothreitol (DTT) assay. In vitro cytotoxic responses were investigated using mitochondrial dehydrogenase (MTT). A significant positive correlation was found between OPmDTT, WSOC, HULIS and the MTT cytotoxicity of PM. Multiple Linear Regression (MLR) showed a good relationship between OPMDTT, HULIS and Cu.

Published: January 2023

Opioids have a rapid transplacental passage (i.e., less than 60 min); furthermore, symptoms characterize the maternal and fetal withdrawal syndrome. Opioid withdrawal significantly impacts the fetus, inducing worse outcomes and a risk of mortality. Moreover, neonatal abstinence syndrome (NAS) follows the delivery, lasts up to 10 weeks, and requires intensive management. Therefore, the prevention and adequate management of NAS are relevant public health issues. This review aims to summarize the most updated evidence in the literature regarding toxicological, clinical, and forensic issues of intrauterine exposure to opioids to provide a multidisciplinary, evidence-based approach for managing such issues. Further research is required to standardize testing and to better understand the distribution of opioid derivatives in each specimen type, as well as the clinically relevant cutoff concentrations in quantitative testing results. A multidisciplinary approach is required, with obstetricians, pediatricians, nurses, forensic doctors and toxicologists, social workers, addiction specialists, and politicians all working together to implement social welfare and social services for the baby when needed. The healthcare system should encourage multidisciplinary activity in this field and direct suspected maternal and neonatal opioid intoxication cases to local referral centers.

Artesunate is the drug of choice for treating patients with severe malaria. Post-artesunate delayed hemolysis (PADH) is an uncommon adverse event from malaria treatment. Most patients with PADH are non-immune travelers. The pathophysiology of PADH is not fully understood, but the most likely mechanism is “pitting”, in which red blood cells carrying dead parasites killed by artesunate’s action are directed to the spleen for clearing the dead parasites. After the cleansing process, these red blood cells re-enter the circulation but with a smaller size and impaired integrity, resulting in a shortened lifespan of 7–21 days. Therefore, most patients with PADH usually present with clinical features of hemolytic anemia 7 days or later after the initiation of artesunate. To date, the benefits of artesunate treatment outweigh its adverse events, and no fatal cases have resulted from PADH. However, the hematological follow-up of patients with malaria treated with artesunate is recommended for clinicians to detect any delayed hemolytic event early and prevent potentially serious consequences.

Authors: Thomas-Wilsker Joshuha
Published: January 2023

This article reviews recent cross-section measurements of tt¯ production in association with a photon, W or Z boson at the Large Hadron Collider (LHC). All measurements reviewed use proton–proton (pp) datasets collected by the ATLAS and CMS experiments between 2016 and 2018 from collisions at a centre-of-mass energy of 13 TeV during the LHC Run 2. Differential and inclusive cross-section measurements are discussed along with the constraints on the effective field theory operators accessible through each process. Finally, we discuss the potential for measurements of these processes at future colliders.

Published: January 2023

This study evaluated the clinical and economic impact of routine pediatric vaccination with the 15-valent pneumococcal conjugate vaccine (PCV15, V114) compared with the 13-valent PCV (PCV13) from a societal perspective in the United States (US). A Markov decision-analytic model was constructed to estimate the outcomes for the entire US population over a 100-year time horizon. The model estimated the impact of V114 versus PCV13 on pneumococcal disease (PD) incidence, post meningitis sequalae, and deaths, taking herd immunity effects into account. V114 effectiveness was extrapolated from the observed PCV13 data and PCV7 clinical trials. Costs (2021$) included vaccine acquisition and administration costs, direct medical costs for PD treatment, direct non-medical costs, and indirect costs, and were discounted at 3% per year. In the base case, V114 prevented 185,711 additional invasive pneumococcal disease, 987,727 all-cause pneumonia, and 11.2 million pneumococcal acute otitis media cases, compared with PCV13. This led to expected gains of 90,026 life years and 96,056 quality-adjusted life years with a total saving of $10.8 billion. Sensitivity analysis showed consistent results over plausible values of key model inputs and assumptions. The findings suggest that V114 is a cost-saving option compared to PCV13 in the routine pediatric vaccination program.

Health Care Professionals (HCPs), including doctors, nurses, pharmacists, and paramedics, are a high-risk group for influenza infection due to their continuous exposure to patients having a known or unknown history of influenza-like illnesses. Influenza vaccination is the most effective method of primary prevention. This study was conducted to assess knowledge, attitude, practice, and barriers associated with influenza vaccination among HCPs at tertiary care hospitals in Lahore, Pakistan. A multicenter analytical cross-sectional study was conducted among HCPs. Data were collected using a structured questionnaire. All statistical analyses were conducted in R software. A total of 400 HCPs were enrolled, and among these, 67% had a high level of knowledge and 65.5% had a positive attitude towards influenza vaccination. About 51% of HCPs adopted good practices leading to influenza vaccination. Results identified major barriers for influenza vaccinations, including unfamiliarity with vaccine availability (RII = 0.760), insufficient staff for administering the vaccine (RII = 0.649), lack of proper storage (RII = 0.625), safety concerns (RII = 0.613), and cost of vaccine (RII = 0.602). More than half of the HCPs showed a high level of knowledge, a positive attitude, and good practice against influenza vaccination. Despite the positive Knowledge, Attitude, and Practice (KAP) scores and published guidelines, a very low percentage of HCPs were vaccinated against influenza. Many hindering factors were associated with influenza vaccination.
Role of Vaccines in Controlling the Spread of COVID-19: A Fractional-Order Model
Authors: Baba Isa , Humphries Usa , Rihan Fathalla
Published: January 2023

In this paper, we present a fractional-order mathematical model in the Caputo sense to investigate the significance of vaccines in controlling COVID-19. The Banach contraction mapping principle is used to prove the existence and uniqueness of the solution. Based on the magnitude of the basic reproduction number, we show that the model consists of two equilibrium solutions that are stable. The disease-free and endemic equilibrium points are locally stably when R0<1 and R0>1 respectively. We perform numerical simulations, with the significance of the vaccine clearly shown. The changes that occur due to the variation of the fractional order α are also shown. The model has been validated by fitting it to four months of real COVID-19 infection data in Thailand. Predictions for a longer period are provided by the model, which provides a good fit for the data.

Published: January 2023

The aim of this study was to investigate the influence of calving-related injuries of the vestibulum vaginae and the vagina on fertility measures in heifers. German Holstein heifers (n = 236) were checked for vestibulum vaginae and vaginal injuries. These were scored according to localization, depth and length. The healing process was assessed until day 42 post partum. Calving ease and the occurrence of metritis and endometritis were evaluated. In 160 heifers, the following fertility measures were calculated to assess the reproductive performance of heifers: mean interval from calving to first insemination, mean days open, mean interval from first insemination to conception, mean calving interval, mean pregnancy index, percentage of animals pregnant at 200 days p.p., and first service conception rate. On the one hand, dystocia was a risk factor for injuries of the soft birth canal, and, on the other hand, those injuries were a risk factor for metritis and endometritis. In this study, calving-related injuries of the vestibulum vaginae and the vagina had no statistically significant effect on the reproductive performance of heifers. One reason for this outcome was probably the overall good healing tendencies of those injuries in heifers.

Myofibroblasts are contractile cells that exhibit features of both fibroblasts and smooth muscle cells. In the synepitheliochorial placenta of the cow myofibroblasts are found in the maternal stroma. However, a deeper understanding of the structure and function of the stromal myofibroblasts in the developed bovine placenta is still missing. Thus, immunohistochemical and ultrastructural analyses in bovine term placentomes, compared to non-pregnant caruncle samples, were conducted. To investigate functional aspects, contractility of placentomal caruncle slices was assessed in an in vitro contraction assay. Additionally, a three-dimensional reconstruction of a bovine placental myofibroblast was created. Immunofluorescent staining revealed a characteristic pattern, including cytoplasmic expression of α-smooth muscle actin, strong perinuclear signal for the intermediate filament vimentin and nuclear progesterone receptor staining. Ultrastructurally, stress fibers, extended cisternae of the rough endoplasmic reticulum and perinuclear intermediate filaments were observed. Moreover, in vitro stimulation with angiotensin-II, but not with prostaglandin F2α, induced contraction of placental caruncle tissue. Altogether, these results indicate that progesterone-responsive myofibroblasts represent a mesenchymal phenotype that is involved in the contractile properties of bovine placental stroma. Therefore, the present findings suggest a potential involvement of myofibroblasts in post-partum events of cattle, i.e., expulsion of fetal membranes and uterine involution.

Early identification of lameness at all phases of lactation improves milk yield and reduces the incidence of mastitis in the herd. According to the literature we hypothesized that there are associations of electrical conductivity variables of milk flow with lameness in dairy cows. The aim of this study was to determine if blood cortisol and electrical conductivity in the milk flow phases correlate with each other and whether they are related to cow lameness. On one farm, out of 1500 cows, 64 cows with signs of lameness and 56 healthy cows were selected with an average of 2.8 lactations and 60 days in the postpartum period. A local veterinarian who specializes in hoof care treatments identified and scored lameness. During evening milking, the milk flow of all 120 cows was measured using electronic milk flow meters (Lactocorder®, WMB AG, Balgache, Switzerland). Before each milking, two electronic mobile milk flow meters (Lactocorders) were mounted between the milking apparatus and the milking tube to take measurements. We found that the average cortisol concentration in the blood of the studied cows was significantly correlated with the laminitis score. Results of this study indicate that the number of non-lame cows with a milk electrical conductivity level of <6 mS/cm even reached 90.8–92.3% of animals. Milk electrical conductivity indicators ≥ 6 mS/cm were determined in 17.8–29.0% more animals in the group of lame cows compared to the group of non-lame cows. According to our study, we detected that blood cortisol concentration had the strongest positive correlation with milk electrical conductivity indicators. Cows with a greater lameness score had a higher cortisol content and milk conductivity.

Published: January 2023

The article shows that many modern scientists believe it was trade that became the prime mover of consistent humankind development. In addition to the exchange of resources, the exchange somehow implied not only material values, but also spiritual ones. Terms from another language were assimilated and transformed; the increased need for knowledge of other languages gave rise to a new specialization, such as translators. Even such subtle spheres of culture as religion were subject to exchange, with ideals and motivation making the foundation for the emergence of other, sometimes very original beliefs. This exchange subsequently led to such a form of the religion spread as missionary work, which made it possible to speed up the propagation of religious ideas over very vast areas. Trade routes became just well-established roads and a convenient route for spiritual expansion. The article considers the Great Silk Road as a channel for the transmission and exchange of cultural and the most significant values of the peoples of this region.

Dietsland Empire?
Authors: Kunkeler Nathaniël
Published: January 2023

Dutch fascism was marked by an international outlook and character from the outset in the 1920s. Rather than a purely Netherlands affair, it had proponents in multiple countries, particularly Belgium and the East Indies (Indonesia). For many of these, the idea of a Great Netherlands territory uniting all Dutch-speaking nations – Dietsland – was central to their international vision. There were a number of Dutch fascist parties and other organisations spread across the globe which experienced limited success throughout the 1920s, notably Flemish fascists in Belgium, and the reactionary Fatherland Club in the Dutch Indies. The latter was the most important, successfully mobilising the white settler population against perceived weakness in the face of Indonesian nationalism and communism. In the early 1930s they became influenced by fascism. The dominant fascist force of the 1930s however was Anton Mussert’s National Socialist Movement, which became a considerable force in the Netherlands, but proportionally even greater in the East Indies. Permitting mixed-race members in the party, it established integrated branches in the colonies where it became the largest political party. An inclusive culturalist notion of Dietsland was central to the party’s international vision and plans for a future fascist Imperium. It took a broadly positive stance towards the colonial administration, pointing to it as a model of fascist rule. This international Dutch fascism was underpinned by a transnational network of members and colonial administrators and army veterans which moved around the Dutch empire. This had a real impact on the development of party ideology, as leaders had to reckon with the influence of the transnational fascist network. However, ultimately metropolitan chauvinism and white supremacism determined the ultimate failure of Dutch fascism in the Indies and the hollowness of the Dietsland myth.

“Pro Arte nas mãos de judeus"
Authors: Vianna Neto Liszt
Published: January 2023

Este artigo aborda as tensões que surgem na Pro Arte, associação de artistas e “amantes" das artes alemãs, a partir de sua tomada pelas autoridades alemãs no Brasil ao final de 1933. Após o Putsch, a associação passou a ser um centro de difusão de propaganda nazista, o que gerou reações tardias do aparato repressor do Estado Novo e da imprensa nacional após a declaração de Guerra aos países do Eixo em 1942. A trajetória da Pro Arte, fundada em 1931, fora precedida pela atuação de seu principal fundador, Theodor Heuberger, que organizava exposições desde 1924. Na Pro Arte, Heuberger tramou cooperações internacionais com a Deutsche Akademie München e a Deutscher Werkbund, duas instituições de prestígio no campo das humanidades e das artes na Alemanha. Os Salões da Pro Arte, organizados por Alberto Guignard, integraram brasileiros e alemães, modernistas e acadêmicos, comunistas e nacionalistas, etc. Sua politica cultural, baseada em exposições, publicações, cursos de línguas, bolsas de estudos, intercambio de artistas e cientistas, etc. Alcançando quase um milhar de associados, a Pro Arte se destacou muito dentre a Deutschtum nacional, o que atraiu a atenção das autoridades alemãs. Curiosamente, a perseguição do aparato repressor do Estado Novo, especialmente do DOPS, não impactou diretamente a Pro Arte, dado que esta era uma instituição cultural brasileira. Os relatos do DOPS contém informações desencontradas, erros grosseiros e todo tipo de especulação - sendo que os danos mais graves à associação se deram nas manchetes dos jornais. Os ecos da propaganda e da política cultural nazista no Brasil através da Pro Arte são o principal objeto desse artigo.
Le temps des hommes et des femmes dans l’entreprise
Authors: Cardia-Vonèche Laura , Bastard Benoit , Gonik Viviane
Published: January 2023

Le présent article propose une réflexion sur le temps des hommes et des femmes dans la sphère du travail professionnel. A partir d’une étude réalisée dans trois entreprises, il met en évidence les biais systématiques qui affectent les représentations relatives à la manière dont les femmes s’investissent dans l’emploi - notamment celles qui concernent le temps partiel, l’absentéisme et les heures supplémentaires. Il suggère aussi que l’affectation des hommes et des femmes aux postes de travail, reposant sur la naturalisation des qualités de chacun des sexes, conduit en pratique à attribuer aux hommes et aux femmes des fonctions qui diffèrent, non seulement par leur contenu, mais aussi par le rythme du travail et les marges d’autonomie dont disposent les employés à l’égard du temps. Les représentations qui en résultent quant au rapport qu’entretiennent les hommes et les femmes au temps du travail sont autant de freins à la progression des femmes dans l’entreprise.
Valeur de service et compétence
Authors: Zarifian Philippe
Published: January 2023

This article proposes a definition of service and its social value which takes its distance from the dominant approaches of economic value. Service is defined as transformation carried out in the conditions cf activity and the possibilities for action of the receiver, and submitted to an evaluating judgement, which can be one of four main types : cf usefulness, of fairness, of solidarity or of aesthetic value. This transformation mobilises and calls on a real professional competence, whose major axis is the clarification and understanding of the events with which the receiver is confronted - demonstrated in their demands not only relative to the range of services which can be offered but to the service providers’ readiness to engage a process of response (which can be extended throughout the back office of the service company). But it remains clear that the professionalism thus implemented is still under-valued. And it will be for as long as a concept of service value has not been sufficiently defined.

Services ou politique. Quelques dilemmes du mouvement des femmes au Québec
Authors: Lamoureux Diane
Published: January 2023

What has been the impact of the growth of service practices on the evolution of feminism in Quebec ? Having situated the origins of these practices and the transforming effects that they have had, the accent is put on the subordinate integration of a part of the “women’s movement” into state management of “women’s problems” and on the possible effects of the social economy on the activities of women’s groups. All this makes it possible to note that women, far from becoming political subjects, are still largely the object of social relations which shape their relationship to the state.

A Critical Review of North Korea's COVID-19 Response Policy: From the Perspective of International Cooperation in the International Health Regulations (2005)
Authors:   Society for International Cultural Institute, Yang Sanghee
Published: January 2023

North Korea has vowed to provide equal health and medical services to all citizens, including free treatment, doctor's care assigned to each area, and preventive medicine, but it is suffering from a recession that began in the mid- to late 1990s and a lack of budget for arms strengthening. In particular, the COVID-19 pandemic in the early 2020s added to this difficult situation. This study criticizes the causes and effects of the Kim Jong-un administration's hasty policy errors in the COVID-19 pandemic, as North Korea's poor health care situation is due to various aspects of politics, economy, and society. This research first introduces the current status and attributes of the North Korean economy, and examines the characteristics of the North Korean health and medical treatment policy based on them. Subsequently, in terms of international cooperation in the International Health Regulations (2005), the North Korean government's COVID-19 pandemic policy is critically reviewed and the policy direction for private cooperation as a non-political means is presented in the conclusion. Finally, this paper argues that in order to effectively supplement the North Korean government's COVID-19 response policy, international solidarity and cooperation, including South Korea, should be promoted transnational, and the International Health Regulations (2005) should be revised to the International Health Law with treaty-level coercion to ensure human mobility as much as possible.
The Impact of Eastern Philosophy on Western Classical Music Education: Focusing on the Influence of Confucianism in China
Authors:   Society for International Cultural Institute, Kim Joonho , Lee Jisun
Published: January 2023

Most East Asian countries have an educational environment based on the spitirual heritage of the Confucian culture. The outstanding performance skills and musical achievements of East Asian performers need to be found in the unique thought and culture of East Asia how classical music originated in the West, especially Europe, was accepted, formed, developed and influenced in these East Asian countries. Throught this study, the successful internalization and performance creation process of Western classical music education in which East Asian value systems are transplanted from other cultures will be explored to reveal the value and expandability of humanistic philosophy inherent in the consciousness of East Asian countries. The educational philosophy of Confucianism, common to all East Asian countreis, has influenced the methods and purposes of the curriculum for a long period of history. In particular, China, the birthplace of Confucianism, has undergone great changes in the negative and positive aspects of traditional Confucianism in modern history, which has an impact on the introduction and spread of Western classical music and the exploration of training methods and spirits for new music styles. This study explored the interaction between the philosophy and art of different cultures by exploring the spiritual and ideological bases for the outstanding achievements of East Asian artists in the process of encountering Eastern philosophy and Western art. In order to enhance the musical perfection of Western classical music, which has been established as the upper culture of music art, oriental values and aesthetic perspectives are affecting the attitude of performers.

Authors:   Society for International Cultural Institute, Li Huiyao
Published: January 2023

Chinese Peking Opera has been promoted and disseminated globally since the beginning of the last century. In this century, with the development of China's economy and the increase of official investment, Peking Opera has reached an unprecedented level in overseas dissemination.
There has been great development in the subject of dissemination, the number of frequency of dissemination, the scope and form of dissemination. However, compared with the huge investment, Peking Opera still cannot become an international drama category. It mostly appears overseas as a symbol of Chinese culture, and there are also many misunderstandings in communication. For example, the functions of communication goals are ambiguous, the form of communication for tour performances is single, the lack of cross-cultural communication talents, and the incomplete communication system.
Therefore, the overseas dissemination of Chinese Peking Opera needs to clarify the dissemination goals and objectives, clarify the main functions of dissemination, improve the content to meet the needs of cross-cultural dissemination, enrich the means of dissemination in form, cultivate and excavate cross-cultural dissemination talents, establish a three-dimensional communication system for exhibition performances, opera education, and folk communication. At the same time, new communication channels such as the Internet should be effectively used, and the communication experience of India, Japan, South Korea and other countries should be used for reference, in order to achieve greater and better effects of Peking Opera overseas communication.

Proses pengukuran volume tangki pendam BBM di SPBU yang saat ini digunakan, masih banyak melakukan proses pengukuran secara manual menggunakan garis ukur atau dipstik. Penelitian ini mengembangkan sistem pengukuran volume tangki pendam BBM secara realtime. Sistem pengukuran ini mengirimkan data pengukuran ke server selama sistem terhubung ke jaringan internet. Sistem pengukuran ini menggunakan sensor ultrasonik untuk mengukur ketinggian permukaan BBM dan menggunakan NodeMCU ESP8266 sebagai kontroler dan pengiriman melalui media wifi. Sensor ultrasonik diarahkan ke dalam tangki pendam dengan posisi tegak lurus terhadap permukaan cairan. Hasil pengukuran jarak diperoleh melalui perhitungan waktu pemancaran transmiter sampai diterima kembali oleh receiver, kemudian perhitungan volume tangki peroleh dari hasil perhitungan jarak di masukan ke dalam persamaan luas tembereng lingkaran tangki yang diproses menggunakan NodeMCU ESP8266 sebagai pengendali utama. Hasil pengukuran volume dikirim oleh NodeMCU ESP8266 ke webserver untuk ditampilkan ke halaman website dan disimpan ke database. Hasil pengukuran volume tangki cukup akurat namun masih terdapat error rata-rata sekitar 1,3%, ini dipengaruhi oleh sedikit lengkungan yang ada pada tangki.

Untuk mencegah adanya gangguan dan kerusakan peralatan pada sistem tenaga listrik diperlukan peranan sistem proteksi. Sistem proteksi yang tidak handal memiliki dampak kerugian ekonomi, hal inilah menjadi dasar para engineer untuk melakukan penelitian optimasi koordinasi proteksi pada sistem tenaga listrik. Penelitian ini bertujuan untuk memastikan sistem proteksi dapat berjalan dengan baik jika terjadinya gangguan hubung singkat pada sistem. Selain itu, penelitian ini untuk mempermudah engineer dalam perhitungan studi koordinasi Directional Overcurrent Relay (DOCR). Berbeda dengan penelitian sebelumnya, dalam penelitian ini mengimplementasikan metode hybrid algoritma pada sistem kelistrikan real dengan mempertimbangkan skema operasi generator. Dengan adanya kondisi operasi generator yang selalu berubah-ubah, kondisi tersebut mempengaruhi waktu kerja DOCR. Untuk mengatasi permasalahan tersebut, perlu melakukan setting DOCR yang optimal dengan menggunakan metode metaheuristik. Hal tersebut menjadi dasar peneliti untuk melakukan penelitian optimasi setting koordinasi proteksi. Setiap metode metaheuristik seperti Differential Evolution Algorithm dan Particle Swarm Optimization memiliki kekurangan dan kelebihan masing-masing dalam proses pencarian optimisasi. Oleh karena itu, penelitian ini mengimplementasikan strategi hybrid algoritma Differential Evolution Algorithm â€“ Particle Swarm Optimization (DE-PSO) untuk mendapatkan nilai Time Dial Setting (TDS) DOCR. Dari hasil penelitian dapat disimpulkan dengan menggunakan hybrid algoritma lebih efisien 83% dari metode non-hybrid.

The meaning of equality in education under Article 31 (1) of the Constitution
Authors:   Korean Constitutional Law Asscciation, Jung InKyung
Published: January 2023

The right to receive education equally under Article 31 (1) of the Constitution is to realize equality in the field of education, and the Constitution ensures equal opportunity for education for all citizens. In the cases of 2016Hun-Ma649 and 2019Hun-Ma212, it was judged whether or not arbitrary discrimination in the standard for college application was treated as an infringement of the right to receive education. However, equality in the field of education guaranteed by Article 31 (1) of the Constitution means fair distribution of resources for the education which are necessary for human growth, and is different from the meaning of prohibition of discrimination in the ‘opportunity’ itself to specific education. Article 31 (1) of the Constitution means that all citizens should have equal access to education, and that the state is obligated to provide necessary educational facilities and systems to the extent that the state's financial ability regardless of various social and economic reasons of its citizens. Therefore, the right to receive education equally under Article 31 (1) of the Constitution is one of the basic social rights, and the purpose is to realize a fair and just society by allowing all citizens to be equally provided with educational conditions or educational environments to develop their abilities. In the cases mentioned, the Court regarded the right to receive education equally as a freedom. However, It is difficult to justify in constitutional theory that the right to receive education equally can be the basis for state authority and the limiting norm of state authority at the same time. This article studies and explains logically that the right to equal education of Article 31 (1) of the Constitution guarantees fair distribution of resources for the education which are necessary for human growth by the state, and it is possible only when the state provides practical educational conditions or educational environments equally to all citizens.
A Constitutional Review of Social Insurance and the Social Vulnerable
Authors:   Korean Constitutional Law Asscciation, Yun Soo Jeong
Published: January 2023

In order for the Constitution to function as a basic law, the political, socioeconomic, and cultural homogeneity of members of the national living community must be premised. In this respect, national homogeneity or the process of forming it is a prerequisite for the constitution to function as a basic law, and on this basis, the constitution has the task of realizing social integration according to various value standards. Social integration refers to the realization of a state in which all citizens can be incorporated into society and function as members of political and socioeconomic communities by protecting and supporting the situation as a necessary condition for realizing freedom, and the risk of life that hinders the realization of freedom. Our Constitution has already included this social integration as a constitutional task, and the Social Security Act regulates it in multiple and multi-layered ways to realize the tasks of this Constitution. In order to realize social integration based on the Social Security Act, primarily, all income-active populations must be protected by social insurance. Our social insurance has been aiming for a low level of equal welfare, and this trend has contributed to the universalization of social insurance. On this basis, various systems should participate to form a complementary and cooperative relationship. Social insurance abstractly protects social risks due to its characteristics. Determining priorities in specific protection for individual situations creates blind spots for protection. And these blind spots should be supplemented through other abstract or specific protection and support. The Social Security Act is a key means of developing one's own abilities to form a life based on self-responsibility and being incorporated into society to realize social integration, but at the same time, it has the task of evolving through continuous innovation by reflecting changes in circumstances.
