Icelandic Lutheran Synod of America and its missionary in Japan, 1916–1941
Authors: Ingvarsdóttir Kristín
Published: January 2023

In 1910, despite low membership and limited funds, the Icelandic Lutheran Synod of America began directly supporting mission work in Asia. It first sponsored a Danish missionary who was serving in India and later commissioned one of its own members, Steingrímur Octavius Thorlakson (1890–1977), to carry out missionary work in Japan, where he ended up serving for 25 years, from 1916 to 1941. Although the synod’s Asia initiative was well known within the Icelandic community, as was Octavius himself during his lifetime, the venture has not become a substantial chapter of the history of Icelanders in North America. The aim of this article is twofold: first, to shed light on the background and nature of the Icelandic Synod’s missionary enterprise in Asia, and second, to examine the initiative and Octavius’ career from the perspective of mobility and international influences in the early 20th century.
En 1910, malgré un faible effectif et des fonds limités, le synode luthérien islandais d’Amérique (Icelandic Lutheran Synod of America) entreprit de soutenir directement le travail missionnaire en Asie. Parrainant d’abord un missionnaire danois qui servait en Inde, le synode envoya ensuite comme missionnaire au Japon un de ses propres membres, Steingrímur Octavius Thorlakson (1890–1977), qui servit pendant 25 ans, de 1916 à 1941. Bien que le projet asiatique du synode était bien connu dans la communauté islandaise, tout comme l’était Octavius lui-même de son vivant, cette entreprise n’est pourtant pas devenue un chapitre important de l’histoire des Islandais en Amérique du Nord. Cet article a deux buts: d’abord, éclairer le contexte et la nature du projet missionnaire du synode islandais en Asie, et ensuite, examiner ce projet et la carrière d’Octavius du point de vue de la mobilité et des influences internationales du début du XXème siècle.

Published: January 2023

Even though corn has been a common agriculture commodity growing by Dompu farmers, few issues remain such as limited input supply especially fertilisers. As results, farmers could not follow the recomended fertiliser doses that lead to low productivity. This study was conducted to clearly identify the issues and constraints along the corn value chain, and identify options to address the issues. Quantitative and qualitative menthods were applied to the study. The findings from this study highlight that the corn value chain was very simple where farmers sell their corn to the village level collectors named as palele, then the palele sell the corn to the sub-district level collecotrs, and then they sell to the exporters. It is the roles of these exporters to sell the corn to other island and or to international markets. Issues found in the corn value chain are: the limited supply of fertilisers, broadcasting technique for fertilizer application, corn price fluctuation, and low corn productivity. It is recomended that the local government take few policy options to address the issues, and improve the value chain performance that lead to better smallholder farmers’ livelihood improvement.

Serum bilirubin levels are negatively associated with atherogenic lipids in Saudi subjects with type 2 diabetes: A pilot study
Authors: Alouffi Sultan
Published: January 2023

Background: Recent research has demonstrated the possible relevance of bilirubin in metabolic and cardiovascular disorders. Lipid abnormalities are a major problem that is related with an increased risk of cardiovascular disease in diabetics. This study examined the relationship between serum bilirubin and direct bilirubin concentrations and atherogenic lipids in patients with type 2 diabetes (T2DM).

Methods: This cross-sectional included 67 patients with type 2 diabetes and 39 matched healthy control. The lipid profile, including total cholesterol, HDL-C, and TG levels, fasting blood glucose, total bilirubin, direct bilirubin, ALT, AST, and ALP were measured using a dimension EXL clinical chemistry analyzer (Siemens Healthcare Diagnostics). Cholesterol in VLDL, LDL, and sdLDL were calculated from standard lipid assay results by the equations of Sampson et al.

Results: Serum bilirubin was lower in non T2DM subjects nearly significant (p=0.0.51) whereas direct bilirubin concentrations were lower in T2DM (p=0.008). ALT, AST, and ALP levels were higher in T2DM groups. The mean values of LDL-C, sdLDL-C, non HDL-C and VLDL-C were significantly increased in T2DM group and lower HDL-C. An inverse relationship could be observed with increase in serum total bilirubin and serum levels of LDL-C (r2=0.139, p<0.005), sdLDL-C (r2=0.137, p<0.005), VLDL-C (r2=0.074, p<0.044), and non HDL-C (r2=0.166, p<0.002) in T2DM group. The same inverse relationship was observed with serum direct bilirubin and serum levels of LDL-C (r2=0.133, p<0.006), sdLDL-C (r2=0.172, p<0.001), VLDL-C (r2=0.118, p<0.01), and non HDL-C (r2=0.182, p<0.001) in T2DM group.

Conclusions: A significant negative association was found between serum bilirubin levels and direct serum bilirubin with atherogenic lipids, suggesting that serum bilirubin may protect T2DM patients from development of cardiovascular disease. These findings indicate the need for additional research in a large cohort.

Authors: Nisa Fifi Khairun , Arliani Elly
Published: January 2023

Mathematical literacy and self-efficacy are critical in learning, especially mathematics. In contrast to previous studies, which only describe mathematical literacy and self-efficacy, this study aims to describe the ability of mathematical literacy in terms of mathematical self-efficacy. This research was a survey research qualitative and quantitative approaches. The results of this study indicate that the mathematical literacy abilities of grade VIII students in junior high school in Yogyakarta with sample 436 students are in a low category and the mathematical self-efficacy in the medium category. The higher the students’ mathematical self-efficacy, the higher their mathematical literacy. Students with high mathematical self-efficacy also tend to keep their maximum effort because they have the confidence to solve math literacy questions. Students with medium mathematical self-efficacy tend to doubt their abilities when facing difficult mathematical literacy questions. Students with low mathematical self-efficacy tend not to be confident in solving them because they think they lack mathematical abilities. This research is expected to map the mathematical literacy abilities of junior high school students in Yogyakarta. Besides, it can make material for reflection in world education to improve it.

There were 146 (39.5%) males and 224 (60.5%) females. The mean age was 31 years. The age range was 22 years to 56 years. One hundred and ninety four (52.4%) were obstetrics and gynaecological surgeries while 176 (47.6 %) were non-gynaecological surgeries. The commonest indication for surgery was caesarean representing 126 (34.1%) of the subject.The distribution of Rh-D positive blood and Rh-D negative blood were 337 (91.7%) and 33 (8.9%) respectively. The prevalence of Rh-D negative blood group was 33 (8.9%) with blood group O Rh-D negative as the commonest 15 (4.1%). Conclusion: Our showed the prevalence of Rh-D negative blood group in surgical patients at the Rivers State Teaching Hospital as 8.9%. Rhesus–D “O” negative blood group was the most common representing 4.1% of Rhesus D-negative blood group. This makes it important in emergency surgical practice as universal donor when there may be to time for typing and matching prior blood transfusion.
Political participation of scheduled caste women through SHGS in west Godavari district of Andhra Pradesh

Published: January 2023

The concept of women empowerment is the outcome of several important critiques and debates generated by the women’s movement throughout the world, particularly by the third world feminists. Empowerment of women means the materialization of the relocation of power challenging the patriarchal ideology which justifies the male dominance. ‘Becoming powerful’ is the literal meaning of the term empowerment. Empowerment can be achieved through transformation of the structures or institutions that reinforce and perpetuate gender discrimination. Empowerment is a process that enables women to gain access to and control of available political, social and economic resources as well as the required information. It is also defined as the process by which the powerless gain greater control over the circumstances and control both resource and ideology that governs their lives. Women’s participation in the village based formal or non-formal organizations has made significant changes in their social status and position in the family. It permits them to participate in rural development for their own upliftment. It also gives them an opportunity to work in groups for common interest, associate with the on-going development programmes, articulate their needs and assume leadership in the national development process. In order to ascertain the political awareness and involvement of the members of the SHG in political affairs, the respondents were asked certain questions to access their political awareness which had an influence in exercising their political right.

Ultra-high strength steels are widely utilized in many applications operating in harsh abrasive wear conditions. For instance, the machineries used in mining and mineral handling or in agricultural sector require robust, but cost-effective wear-resistant materials. Steels provide excellent combination of mechanical properties and usability. This study encompasses mechanical and wear testing of an experimental medium-carbon press-hardening steel. The as-received material was austenitized at two different temperatures and quenched in water. Additionally, low-temperature tempering was applied for one variant. In total, three variants of the press-hardening steel were produced. Microstructural characterization and mechanical testing were conducted for the steel samples. The wear testing was carried out with high-stress abrasive method, in which the samples were rotated inside a crushed granite bed. A commercial 400 HB grade wear-resistant steel was included in the wear testing as a reference. The experimental steel showed very high mechanical properties reaching tensile strength up to 2600 MPa with hardness of 750 HV10. Wear testing resulted in only minimal differences between the three variants indicating that the improved impact toughness by tempering did not significantly affect the wear resistance. The reference steel had nearly two times greater mass loss compared to the higher hardness press-hardening steels. Microhardness measurements on the worn surface showed drastic increase in hardness for the deformed structure for all samples. It was concluded that even the high-hardness martensitic steels exhibit notable wear surface work-hardening. Therefore, hardness was determined to be the most significant factor affecting the wear performance of studied steels.
Reposisi Dialektis Tafsīr Lughawī: Pergeseran Integratif Pendekatan Linguistik dalam Wacana Tafsir Kontemporer
Authors: Hakim Muhammad Naufal , Abd. Kholid
Published: January 2023

This article aims to re-read the position of tafsīr lughawī in contemporary interpretation discourse. The background of the research is the fact that contemporary interpretation methodologies have emerged which seem to nullify linguistic reviews in interpretation. Using the critical-analytic method and the historical-philosophical approach, three points are examined: 1.) typology which includes book mapping, commentator, and interpretation methods; 2.) genealogy from its inception to its development; 3.) existential reading of tafsīr lughawī. This study infered 20 mapped tafsīr lughawī book not only use the manhaj al-lughawī but also the manhaj al-adabī, al-balāghī, and al-bayānī. The genealogy of the interpretation of the Qur’ān using a linguistic approach has existed since the time of the Prophet, the Companions, and the Tabiin, then continued until the emergence of interpretation books using lughawī style since the 2nd century Hijri. The main characteristic of tafsīr lughawī is the use of al-‘ulūm al-‘arabiyyah as the interpretating device, such as qawā‘id al-lughah (naḥw and ṣarf), ‘ulūm al-balāghah (ma‘ānī, bayān, and bādī‘), qiraah, and Jāhili Arabic poetry. In contemporary interpretation discourse, tafsīr lughawī is repositioned, in which the rules of interpretation are still used, but the lughawī style is no longer the dominant one for its integration-interconnection with other disciplines to produce a more in-depth and contextual interpretation.

Hacia un black metal postsatánico
Authors: Rivero-Vadillo Alejandro
Published: January 2023

El presente artículo realiza un análisis del álbum Litourgiya (2015) de la banda polaca de black metal Batushka (estilizada comercialmente como Батюшка). El estudio se centra en el acercamiento espiritual de la banda a la cuestión del satanismo, la cual ha permeado la historia de este subgénero de metal desde sus inicios. Tras una breve introducción a las bases de este género musical, el artículo contextualiza el funcionamiento de la espiritualidad satánica en las letras del black metal haciendo uso de diversos estudios dedicados a la misma. Posteriormente, se realiza un estudio de la forma en la que Batushka rompe los moldes previamente asentados y normalizados en la lírica del género, creando un enfoque que deconstruye el binarismo divino/demoníaco asociado a esta música. Por un lado, las letras de Litourgiya muestran una aproximación a “lo satánico” que no se corresponde con las lógicas de oposición e inversión teológica argumentadas por diversos críticos, pues no solo no muestran referencias a Satán, sino que, se apropian de textos integros y cantos litúrgicos de la Iglesia Ortodoxa. Por otra, la banda hace uso de elementos propios de la teología ortodoxa eslava, especialmente la idea de la theosis que, a diferencia de las bases católicas/protestantes del género, permiten un escape poético del binario divino/demoníaco que nutre la lírica de esta música.
Перевод и переводчики в литературной системе Сергея Довлатова
Authors: Savchenkova Margarita
Published: January 2023

В статье анализируется подход Сергея Довлатова, представителя третьей волны русской эмиграции в США, к проблеме перевода и фигуре переводчика. На материалах довлатовских повестей и рассказов, наряду со статьями, письмами, эссе и интервью, прослеживается противоречивое отношение писателя к переводческой деятельности и неоднозначное восприятие им переводческой профессии. Высоко оценивая американскую переводную литературу, автор многократно снижает значимость переводов с русского на английский, указывая тем самым на превосходство русского литературного перевода и языка над английским. Им предлагается ряд рассуждений относительно перевода собственного творческого наследия, роли переводческих практик в контексте литературы СССР и непереводимости некоторых русских слов и явлений советской действительности. В творчестве писателя можно заметить четкое разграничение между женщинами-переводчиками, рассматривавшимися как объект мужского желания, и мужчинами-переводчиками, представленными на страницах книг Довлатова в виде комических героев. Между тем, как показывает анализ, в жизни и работе самого прозаика обнаруживаются черты, свойственные профессии переводчика. Наши замечания и выводы касательно места перевода и фигуры переводчика в рамках довлатовских текстов подкреплены научными исследованиями в области переводоведения, а также публикациями, посвященными произведениям Довлатова.

MENTORING ISLAMIC RELIGIOUS VALUES FOR DROPOUT STUDENTS IN KALIBARU MANIS VILLAGE BANYUWANGI
Authors: Sulmiftah Haris , Mansur Rosichin , Muslim Moh.
Published: January 2023

Islamic religious values become a barometer of character education for students. Dropping out of school has a negative impact on a child's development, and has a social impact on society. This study aims to describe the mentoring of Islamic religious values to dropout students, analyze the method of mentoring Islamic religious values, and provide an overview of the inhibiting factors for mentoring Islamic religious values to dropout students. The researchers use a qualitative method with a case study approach. Researchers used in-depth interviews, participant observation, and document study techniques. The results of the study provide an overview of students dropping out of school through non-formal education study groups getting assistance with Islamic religious values ranging from the values of wisdom, honesty, faith, morals, and basic values. Islamic religious values are implemented through mentoring methods including: habituation methods, exemplary, and mau'izah hasanah (good advice). Obstacles during the process of mentoring Islamic religious values to dropout students include: (1) the economic condition of the community below the poverty line; (2) laggard community culture; (3) lack of parental attention to children's education; (4) the unavailability of learning facilities at the junior high school level; and (5) the location of the school which is far from the community's house. So, parents and students dropping out of school have to spend more money, time, and energy to travel to the nearest school. However, the implication that occurs when education access is not available is that more dropout students do not get the 12 year compulsory education service as announced by the government.
