Published: July 2022

Background: Pneumococcal prime-boost vaccination is recommended for solid organ transplant recipients and candidates. The long-term durability of the antibody (AB) response is unknown. The same applies to a dose-dependent immune response. Methods: We studied the durability of the vaccine response after 18 months in kidney transplant recipients (KTRs) and patients on the kidney transplant waiting list (WLPs). Both groups received either a normal dose (ND) or a double dose (DD) of the 13-valent pneumococcal conjugate vaccine and the 23-valent pneumococcal polysaccharide vaccine. The average pneumococcal AB geometric mean concentration (GMC) was evaluated. A level ≥ 1 mg/L was considered protective against invasive pneumococcal disease (IPD). Results: Sixty WLPs and 70 KTRs were included. The proportion of participants protected declined from 52% to 33% in WLPs and from 29% to 16% in KTRs, with the previously significant dose-effect in WLPs no longer present (40% DD vs. 27% ND; p = 0.273). Average pneumococcal AB GMCs remained significantly above baseline levels (all groups p ≤ 0.001). Drug-induced immunosuppression diminished the vaccine dose-effect. Conclusions: At follow-up, the pneumococcal prime-boost vaccination still provided significantly elevated average pneumococcal AB GMCs in both populations. Though the proportion of participants protected against IPD in WLP-DD and WLP-ND were statistically comparable, a DD may still be recommended for WLPs (EudraCT: 2016-004123-23).

Private Foundations and Donations to Orthodox Churches and Monasteries in the Grand Duchy of Lithuania in the Late 14th–early 16th Century

The oldest foundation and donation related documents intended for Orthodox churches and monasteries and issued by private persons date back to the late 14th century. Until the mid- 15th century only isolated documents are available, however starting with the 1440s the number of documents gradually increases up to the very beginning of the 16th century. In total, 107 documents are known (their register is presented in the article). Throughout the period under investigation most of the document drawers were regional dukes (mostly the Gediminids, several Rurikids), however, starting with the middle of the 15th century persons of noble descent were also recorded among the document drawers. 32 different locations where Orthodox churches and monasteries were provided for have been detected (mostly in the duchies of Kiev, Mstislavl, Pinsk, and Slutsk). The largest number of grants (15) were issued for the maintenance of Kiev Pechersk and Pustynsk monasteries which suggests of the importance of Kiev as the centre of religious authority. Document subscriptions indicate that most of the persons who wrote these documents were laymen.

Activities of Notaries Public in the Dioceses of the Grand Duchy of Lithuania in the 16th Century

This is a research of the notaries public as a corporate group. The research deals with the issues pertaining to the existence of a certain network of notaries public in the dioceses of Vilnius, Samogitia, and Lutsk in the Grand Duchy of Lithuania and their correlation in the space of notaries public of the province of the archdiocese of Gniezno in the 16th century. The period under investigation is chronologically enframed by two dates. The first conditional date is 1501 which marks a stage in the maturity of the notarial system when the clergymen of the GDL started being awarded the honorary title – Count of the Sacred Palace of Lateran (comes apostolicus) accompanied by the right granted by the Pope to delegate notaries public (the Emperor could also award the title of the count of the palace). The said right was usually exercised by bishops, church officials, and notaries general. 1515 is considered an interim important date in the research as this was the year when the statutes of local dioceses of the Grand Duchy of Lithuania were drawn up and the first wording of Vilnius cathedral chapter statutes, for the first time mentioning the participation of the notary public in the life of the chapter and his functions, was carried out. The second date is 1566 – the year when the Second Statute of Lithuania legitimized the activities of notaries public on the national level throughout the GDL. The said dates mark the dynamics and spread of the notarial system – introduced through the institution of the Church, the function of the notary public gradually entered the sovereign’s chancellery, noblemen, following the example of the sovereign, started using the services and notaries public gradually found their way to municipal institutions of towns and cities. The codification dates of the two separate structures of government – the church and secular authorities – can be equally applied to mark the development stages of the notarial system as they indicate the process of notary public participation in both – the church and state government institutions.

Authors: Alvira Regina Claudia
Published: July 2022

The ceramic products discussed in this paper are hand-processed ceramic tableware with a competitive advantage in using the glazing technique at Naruna Ceramic Studio (NCS), Salatiga, Central Java, Indonesia. This technique is a coloring method after the first combustion of a ceramic kiln that can give a characteristic to the product giving an attractive and elegant color impression that can increase sales turnover and competitiveness of NCS compared to similar. The COVID-19 pandemic that continues to exist in Indonesia forces the number of customer sales to not be able to interact directly with NCS, so it is necessary to change a new marketing strategy carried out by NCS to increase turnover. The digital marketing method in this paper is applied by the author and NCS to market handmade ceramic tableware products with a finishing process using the glazing technique. The Digital Marketing System applied by NCS and researchers is to build an advertising platform that can influence consumer behavior so that it can make a significant contribution to increasing the turnover of this ceramic product seller. The ads that posted on Facebook, Instagram, YouTube, TikTok, and Website will be done will be based on the landing page which ends in the marketplace (Shopee, Tokopedia) and the WhatsApp application which is managed by NCS customer service. The final results up to October 2020 showed an increase in turnover of 65% after the implementation of this DM was implemented

Rituals and Beliefs of the Karisal Region People in the Works of K. Rajanarayanan
Authors: A Amutha
Published: July 2022

Regional literature is one of the emerging disciplines of today. Regional writers create their work to reflect the lifestyles of the people in their community. In that aspect, in the writings of K. Rajanarayanan, the pioneer writer of the Karisal region, the people of the Karisal region are only included. In all of his works, KR has recorded his own soil, people, and also their roots. He narrates soulful stories without embellishing them decoratively. Beliefs are created by people, and those people are protected by society. Rituals and beliefs play a major role in man's perception of himself and society. Since the primary occupation of the Karisal people was agriculture, they were in close contact with nature. During the festivals, these people imprint the design of the trident "Sulam Saathi" on the back of a beautiful calf and bestow it on the temples. In the wedding rituals of these people, the wedding will take place over three days. The bride and groom will be led in a procession. The ritual will be held during the day. In his works, KR mentions in his literary works that these people are emigrants from the Telugu state and have high faith in Perumal and will go to see him only after God appears in a dream and invites them. Rain is man's lifeblood, and life cannot exist without it. Life will be questionable if it does not rain. The people of the Karisal region, who consider agriculture as their main occupation, are forced into extreme poverty because of severe drought when the monsoon season fails. These people, who depend on the rain for their livelihood, perform some rituals to make it rain. There was a belief among the people that if they went from house to house together and poured the cooked porridge of various grains into a bowl, mixed it together, and drank it as rain porridge, it would rain. They do not forget the soil, whether it rains or doesn’t rain. As they set up their lives depending on the soil, the affectionate feeling they have for the soil can be traced back to the role of the Annarapaakka gounder. The purpose of this article is to explore the rituals and beliefs mixed with the life of the Karisal region in the works of K.R.
Caldwell's Educational Service on ‘Karisal Mann’ (Black Soil)
Authors: J Raja Sornam
Published: July 2022

The Gurukul system of education was only available in a few places in ancient India. Christian missionaries transformed this condition, establishing the current educational system and bringing education to all people, regardless of caste, creed, colour, or social rank. Robert Caldwell, in particular, made significant contribution in providing education to the poor in South India throughout the nineteenth century. In Idayangudi, Tirunelveli, he undertook various reformatory activities in the areas of gospel, Tamil language, society, medicine, and education. Robert Caldwell was born in Antrim, Ireland, in 1814. He went to Glasgow University to study. He was an expert in English, Tamil, and Religious Texts, as well as art. He was fluent in Tamil, English, Greek, Telugu, and Sanskrit, among other languages. In 1841, he went to Tirunelveli's Idayangudi in South India as a missionary under the London Missionary Society. He revitalised the  boy's school which was begun by Rev. Iranius. In 1842, Caldwell also founded the Girl's School. These schools taught subjects like Tamil, English, Geography, and History. He founded Anglo Vernacular Schools to teach English and Tamil letters to youngsters who did not know English. He established schools in places like Tharuvai, Ramanathapuram, Samugarengapuram, Kulasegaran Pattinam, Azhvar Thirunagari, Tuticorin, Arumangalam, Thenthiruperai, and Thatanpadam. Caldwell stayed in Idayangudi for more than 50 years, bringing about significant changes for the illiterate. Caldwell's legacy lives on in the hearts of the people and has fused with the Chernozem soil, as evidenced by educational institutions and researchers who have benefited from them.

Breves Considerações sobre o Processo Estrutural à Luz da Jurisprudência do Superior Tribunal de Justiça e das Proposições Previstas no PLS 1.641/2021
Authors: Batista Fernando Natal
Published: July 2022

A partir do exame evolutivo da structural injunction no direito norte-americano, mormente do caso Brown vs Board of Education of Topeka, percebe-se, atualmente, em nosso ordenamento processual, o engajamento de um movimento de democratização da prestação jurisdicional na solução das lides complexas, de execução plural pelos diversos agentes públicos e privados envolvidos em um problema polimórfico: o processo estrutural, que, ante um estado de desconformidade de direitos fundamentais, surge como forma de solução judicial de políticas públicas não implementadas ou insuficientes. O presente artigo tem como proposta metodológica abordar o tema do processo estrutural ou estruturante, após breves considerações de sua generalidade, sob o prisma de sua interpretação pela jurisprudência do Superior Tribunal de Justiça e, ainda, quanto à sua normatização prevista no Projeto de Lei 1.641/2021, atualmente em trâmite no parlamento.
Ação Coletiva Passiva como Estratégia para Implementação de Boas Práticas de Governança Corporativa
Authors: De Oliveira Larissa Cerqueira
Published: July 2022

A discussão quanto à admissibilidade de processos coletivos passivos é relativamente recente na doutrina brasileira. Apesar de não haver regulamentação expressa, a ação coletiva passiva ou defendant class action tem sido admitida em hipóteses especiais. Todavia, embora existam nos projetos de Código para Processos Coletivos a previsão de ações coletivas passivas, há divergência quanto à viabilidade dessa modalidade de ação à luz do ordenamento brasileiro. Na proposta aqui trazida, busca-se analisar a possibilidade de propositura da ação coletiva passiva amparada nos princípios norteadores do acesso à justiça e inafastabilidade da jurisdição, em face das associações como estratégia para implementação de boas práticas de governança corporativa. Como metodologia de pesquisa, aplicou-se a técnica de revisão bibliográfica de cunho exploratório.

Negociação na Tutela Coletiva: Incompatibilidade ou Adequação?
Authors: Almeida Vieira Isabelle
Published: July 2022

O presente estudo tem por objetivo analisar a possibilidade de negociação na tutela coletiva. A adoção de um sistema de justiça multiportas prioriza a realização de acordos, inclusive quando se tratar de ações coletivas. Embora as ações coletivas veiculem direitos transindividuais, os quais são considerados indisponíveis, isso não resulta na impossibilidade de negociação, desde que observadas certas limitações. O perfil pacificador adotado pelo atual sistema processual civil mitiga a ideia da indisponibilidade absoluta de certos direitos. Ademais, a Lei nº. 13.140/2015 (Lei de Mediação) traz uma terceira categoria de direitos, qual seja, os direitos indisponíveis que admitem transação, confirmando a tese de que determinados direitos indisponíveis também podem ser objeto de negociação.

ABSTRAKTelah dilakukan penelitian tentang pemanfaatan selulosa tongkol jagung pada pembuatan plastik biodegradable, untuk mengetahui pengaruh konsentrasi sorbitol terhadap sifat mekanik, biodegradabilitas dan ketahanan air. Penelitian ini dilakukan dalam beberapa tahap, yaitu preparasi bahan, pembuatan plastik dengan metode inversi fasa dengan variasi konsentasi plasticizer sorbitol, serta karakterisasi. Hasil penelitian menunjukkan bahwa penambahan plasticizer sorbitol 30% menghasilkan plastik biodegradable yang lebih baik karena memiliki ketahanan air maksimum yaitu 28,38% dan terdegradasi 90.24% dalam waktu 9 hari. Kuat tarik plastik tertinggi diperoleh pada penambahan plasticizer sorbitol 10% yaitu 2,7750 MPa dan elongasi terbaik diperoleh pada penambahan  sorbitol 50% yaitu 16,94% . Hasil interpretasi gugus fungsi menggunakan spektrofotometer FTIR mengindikasikan adanya gugus OH pada bilangan gelombang 3417 cm-1, pada bilangan gelombang 2935 cm-1 menunjukkan adanya vibrasi CH2 yang merupakan kerangka pembangun struktur selulosa, gugus C-O nampak pada bilangan gelombang 1342 cm-1 dan 1209 cm-1 sedangkan gugus NH2 nampak pada bilangan gelombang 1641 cm-1. Berdasarkan data tersebut maka plastiik biodegradable tongkol jagung yang dihasilkan belum memenuhi SNI.Kata kunci: Plastik, Biodegradable, Sorbitol, Jagung dan Selulosa ABSTRACTA study has been conducted on the utilization of corncob cellulose on synthesis biodegradable plastic. This study aims to determine the effect of plasticizer addition to mechanical properties, biodegradability and water resistance, and to know the right type of plasticizer to produce biodegradable plastic that suits SNI. This research was conducted in several stages, namely material preparation, biodegradable plastic making with phase inversion method with variation of plasticizer concentration of sorbitol, and characterization of biodegradable plastic. The results showed that the addition of 30% of sorbitol produced better biodegradable plastic than because it has maximum water resistance of 28,38 % and degradation 90,24% within 9 days while the highest plastic tensile strength is 2.7750 MPa with concentration of  sorbitol 10% and the best elongation of 16.94% concentration of  sorbitol 50%. Based on the analysis of functional groups using FTIR spectrophotometer, it can be seen the absorption of the wave number at 3417 cm-1 which indicates the presence of the OH group, the wave number at 2935 cm-1 indicates the existence of vibrations CH2 which is the building framework of cellulose structure, the CO group is seen at wave numbers 1342 cm-1 and 1209 cm-1 whereas NH2 groups at wavelength 1641 cm-1. Based on these data biodegradable plastic corncob do not meet SNI.Keywords: Plastics, Biodegradable, Sorbitol, Corn and Selulose
