Наследственные нарушения соединительной ткани - это обширная группа генетически и клинически гетерогенных заболеваний, развитие которых обусловлено мутациями генов, ответственных за синтез белков внеклеточного матрикса или участвующих в морфогенезе соединительной ткани. Данная статья посвящена результатам поиска молекулярно-генетических причин редких наследственных заболеваний соединительной ткани - синдрома Элерса-Данло, несовершенного остеогенеза и остеопетроза. Диагностика этих заболеваний осложняется сходством симптомов и степенью выраженности клинических проявлений. Представленные результаты расширят представление о молекулярном патогенезе наследственных болезней соединительной ткани и позволяют оптимизировать диагностику данной группы заболеваний, тактику медико-генетического консультирования отягощенных семей и оказания им медицинской помощи.

Hereditary connective tissue diseases are a large group of genetically and clinically heterogeneous diseases whose development is caused by mutations in the genes responsible for the synthesis of extracellular matrix proteins or involved in connective tissue morphogenesis. This article is devoted to the results of the search for the molecular genetic causes of the rare hereditary connective tissue diseases: Ehlers-Danlos syndrome, osteogenesis imperfecta and osteopetrosis. Diagnosis of these pathologies is difficult because of the similarity of symptoms and their clinical manifestations. The presented results will expand the understanding of the pathogenesis and will allow to optimize the diagnosis of these syndromes, to determine the tactics of medical and genetic counseling of burdened families by both clinical geneticists, orphan disease specialists, and general practitioners, family medicine specialists, and general practitioners.

На сегодняшний день не существует нейропротекторных препаратов для лечения распространённого нейродегенеративного заболевания болезни Паркинсона (БП). Наиболее перспективной для разработки тагретной терапии считается форма БП, ассоциированная с мутациями в гене GBA (GBA-БП), как самая распространенная форма БП с известной этиологией. Мутации в гене GBA, кодирующем фермент глюкоцереброзидазу (GCase), приводят к снижению активности данного фермента. Ранее было показано, что ингибирование киназной активности LRRK2 ингибитором MLi-2 приводит к увеличению активности GCase. В данном исследовании мы впервые показали влияние ингибитора киназной активности LRRK2 MLi-2 не только на активность GCase, но и на активность других лизосомных ферментов в первичной культуре макрофагов периферической крови пациентов не только с LRRK2-ассоциированной БП (LRRK2-БП), но и с GBA-БП.

To date, there are no neuroprotective drugs for the common neurodegenerative disease, Parkinson’s disease (PD). PD associated with mutations in the GBA gene (GBA-PD) is the most common form of PD with a known etiology. GBA-PD is considered the most promising for the development of therapy for PD. Mutations in the GBA gene encoding the enzyme glucocerebrosidase (GCase) lead to a decrease in the activity of this enzyme. Previously, it was shown that inhibition of LRRK2 kinase activity by MLi-2 inhibitor leads to an increase in GCase activity. In this study, we showed for the first time the effect of the LRRK2 kinase activity inhibitor MLi-2 not only on the activity of GCase, but also on the activity of other lysosomal enzymes in the primary culture of peripheral blood macrophages of patients with LRRK2-associated PD (LRRK2-PD) and GBA-PD.

Published: January 2023

Расчет теплопоступлений через ограждения является важной частью задачи прогнозирования летнего теплового режима здания под прозрачным куполом, интерес к строительству которых в северных регионах возрос в последнее время. В работе рассмотрена относительно простая, пригодная для инженерных расчетов модель теплопередачи через ограждающую конструкцию с полупрозрачным экраном, позволяющую учесть парниковый эффект. Для верификации модели было проведено сравнение расчетных и экспериментальных данных и получено их хорошее согласие, что подтверждает работоспособность предложенной модели. Показано, что наличие полупрозрачного экрана из-за парникового эффекта значительно изменяет температуру стены здания под куполом и величину теплового потока, откуда следует важность учета таких факторов, как оптические свойства экрана, температура небесного свода и других климатических факторов при расчете теплового режима купольных систем.

The evaluation of heat input through fences is an important part of the task of predicting the summer thermal regime of a building under a transparent dome, the interest in the construction of which in the northern regions has increased recently. In this work, a relatively simple model for engineering calculations of heat transfer through a building envelope with a translucent screen, which allows to take into account the greenhouse effect, is considered. The model has been verified by comparing the calculated and experimental data and their good agreement has been obtained, which confirms the performance of the proposed model. It is shown that the presence of a translucent screen due to the greenhouse effect significantly changes the temperature of the building wall under the dome and the value of heat flux, which implies the importance of taking into account such factors as the optical properties of the screen, the temperature of the sky, and other climatic factors when calculating the thermal regime of dome systems.

Published: January 2023

The new normal era during the COVID-19 pandemic has presented opportunities and challenges for SMEs. This study aimed to determine the effects of absorptive capacity and innovation capability on business performance. The research involved 189 creative SMEs owners in Malang City. The sampling technique uses proportional random sampling. Data were collected by distributing questionnaires to respondents. The data analysis used partial least squares using high-order construction. The results showed that absorptive capacity significantly affects business performance, and absorptive capacity significantly affects innovation capability. However, innovation capability had no significant effect on business performance. Innovation capability has also not been proven to influence Absorptive Capacity and Business Performance indirectly. The practical implication is that SMEs owners should develop the absorptive capacity to reach, assimilate, and acquire new knowledge to achieve better SMEs performance. Simultaneously, innovation capability does not automatically improve SMEs' performance. SMEs need extra effort to produce innovations that are rare, unique, and difficult to imitate to survive the new normal era. JEL : D81, M13, O31.ABSTRAKEra new normal di masa pandemi COVID-19 menghadirkan peluang dan tantangan bagi UMKM.

In the following case report, we present two clinical cases of patients after valvular intervention and percutaneous occluder implantation into the left atrium. The first patient is a 68-year-old male admitted to the Department of Cardiology because of Non-ST-Elevation Myocardial Infarction (NSTEMI). He had a medical history of paroxysmal atrial fibrillation and implantation of a biological mitral prosthesis due to severe secondary mitral regurgitation. Due to contraindications to the chronic use of anticoagulants, the patient underwent percutaneous closure of the left atrium appendage. The second patient is an 80-year-old man with a history of permanent atrial fibrillation. 8 years ago, the patient underwent percutaneous atrial septal defect type II (ASD II) closure with and the Amplatz occluder. A year later, the patient underwent Coronary Artery Bypass Graft (CABG) and biological mitral valve implantation due to multivessel coronary disease accompanied by severe mitral regurgitation. In both patients, Transthoracic Echocardiogram (TTE) showed massive thrombosis in the left atrium.

Published: January 2023

Background: Diffuse Large B-Cell Lymphoma (DLBCL) is the most common subtype of Non-Hodgkin lymphoma (NHL). DLBCL is a heterogenous disease and is the most common subtype of NHL occurring in Human Immunodeficiency Virus (HIV) seropositive individuals. Aim: The aim of the study was to review the clinical profile as well as the outcome of adult patients presenting with DLBCL, to a tertiary public sector hospital (Chris Hani Baragwanath Academic Hospital – CHBAH) in Soweto, Johannesburg, South Africa. Patients and Methods: The study entailed a retrospective review of 139 evaluable patients with DLBCL, over a 5 year period. Results: Of the 139 patients reviewed, there were 73 females (53%) and 66 males (47%), with a female: male ratio of 1.1:1. The median age of the patients was 41 years (14-85). Common presenting features included advanced stage disease (83%), constitutional or ‘B’ symptoms (74%), extra-nodal disease (73%) and lymphadenopathy (64%). 81% of the patients were HIV seropositive. The median overall survival was 24 months. Conclusion: DLBCL accounted for 35% of all the patients with NHL during the study period. HIV seropositivity, together with other factors such as significant delays in referral of the patients, late presentations with advanced stage disease, and comorbidities such as Tuberculosis, impacted negatively on the prognosis and the outcome of the patients with DLBCL. Despite the use of Combination Antiretroviral Therapy (cART), appropriate supportive care and specific modalities of treatment, DLBCL continues to pose a challenge in our clinical setting.
De-solvation of metal complexes to construct metal-organic framework glasses
Authors: Wei Yong-Sheng , Fan Zeyu , Luo Cheng , Horike Satoshi
Published: January 2023

Structural fine-tuning is an important challenge in the chemistry of metal-organic framework (MOF) glasses. Current approaches of thermally/mechanically-induced vitrification are limited for azolate/cyanide-based crystalline MOFs, while other MOF crystals usually decompose before melting or amorphize upon milling instead of forming stable glasses. Here, we developed a general method, “de-solvation” of solvated metal-ligand complexes to gently prepare MOF glasses by demonstrating 12 ligands of varying lengths, shapes, side- and coordination-groups (carboxylate/pyridyl/azolate). Hydrogen-bond networks of the metal complexes offer the spatial arrangements of metal-ligand units, thus guiding the glass formations during de-solvation. The prepared glasses have high structural diversities with tunable pores (sizes and modifications) and dimensionalities (one to three), and high glass-forming abilities with wide transition temperature windows from 120 to 280 °C, affording grain-boundary-free/transparent monoliths under heating without pressure.

Published: January 2023

Generalized periodontitis is accompanied by progressive bone atrophy of the alveolar process of the jaws. The first signs of osteoporosis appear in the alveolar process already in the early stages. Complex treatment of generalized periodontitis includes, first of all, an etiopathogenetic approach. The object of the study is to investigate the effectiveness of biotherapeutic correction of osteoporosis of the alveolar processes of the jaws in the complex treatment of patients with generalized periodontitis adding melatonin and vitamin D. The study involved 121 patients aged from 26-40 years with generalized periodontitis of initial-I and I stages with a chronic course, and 45 apparently healthy volunteers from the control group. All patients gave voluntary informed consent to participate in the study. Groups of patients were randomized approximately by same age and gender. Before onset of treatment and 6 months after the complex treatment the level of vitamin D and melatonin level was measured and examined for osteoporosis using a cone-beam computed tomography. In order to give a qualitative and quantitative assessment of the state of mineralization of the spongy and compact bone tissue of the alveolar processes of the jaws histographic analysis of computed tomography was used. 55 patients in addition to traditional local treatment were added vitamin D intake of 4000 IU/d with meals and melatonin intake of 1.5 mg at bedtime for 1 month. It was stated, that level of melatonin in saliva is inversely proportional to the level of vitamin D in the blood serum in patients with generalized periodontitis and patients from the group with clinically healthy periodontium. Using  melatonin and vitamin D in the complex of treatment of patients with generalized periodontitis leads to an increase X-ray density of bone tissue of the alveolar processes of the jaws, which allows to achieve restoration of bone density of alveolar processes and longer stabilization of dystrophic – inflammatory process in the periodontium. To strengthen the bone tissue of the alveolar processes of the jaws in patients with generalized periodontitis, it is advisable to use  melatonin and  vitamin D in a complex treatment.
Target Date Funds: Current Status and Issues
Authors: Park Heejin
Published: January 2023

Target date funds (TDFs) have their portfolios periodically adjusted according to the retirement dates of fund subscribers and are generally composed of several funds. TDFs attract attention in the recent pension market due to the increasing role of private pensions, the concern about the depletion and financial instability of the National Pension Fund, increased interest in stock and fund markets after COVID-19, and the introduction of the retirement pension default option. In particular, target date funds seeking globally diversified investment strategies could change the irrational investment behavior of pension assets that are still mainly invested with principal and interest-guaranteed products and consequent low returns. To this end, this study examines the current status and issues of TDF in the United States and Korea, and proposes ways to develop domestic TDF in the right direction.
Utilization of Weekly Options for the Improvement of the Volatility Index
Authors: Kang Tae Hun
Published: January 2023

As the liquidity of KOSPI 200 index options is concentrated on the nearest expiration contract, the V-KOSPI 200 index, which is based on near- and next-term months options, fluctuates abnormally, and the designated market makers of V-KOSPI 200 futures suffer from hedging their inventory positions. This study suggests the volatility index, which includes KOSPI 200 weekly options instead of next-term monthly options. The index can mitigate rare spikes and the low volatility of the V-KOSPI 200 index, which mainly arise from stale market prices and low-frequency trading in the second and third contract months. The empirical results show that the monthly trading volume of weekly options more than triples compared to second- and third-contract month options, and the microstructure of both markets is roughly similar. The trading frequency of weekly options is six times higher than that of next-term monthly options. Therefore, V-KOSPI 200 futures market makers can use weekly options traded more actively instead of second-month options as components of hedging portfolios, while helping the new volatility index mitigate the abnormal fluctuation of the V-KOSPI 200 index.
Cost Sensitivity Analysis on Merchant Discount Rates
Authors: Jo Yoonseo , Lee Kaun Y.
Published: January 2023

Credit card companies provide payment services between merchants and members (i.e., cardholders) and charge merchant discount rates and annual membership fees, respectively. There is a discriminatory price structure in which merchants pay a higher commission rate than members because of the recognition that the utility of merchants is relatively greater than that of members and they have an obligation to accept cards. To prevent aggravating the burden on merchants due to the discriminatory price structure, regulations on the merchant discount rate were adopted in Korea. This study suggests a direction to improve the understanding of the credit card markets and to solve structural problems through a cost sensitivity analysis of merchant discount rates determined in the qualifying cost system introduced by the Financial Services Commission. First, we found empirical evidence that the effect of changes in each cost ratio on the merchant discount rate (price) differs depending on the intensity of the cost regulation (regulation effect). In addition, the merchant discount rate was lowered by government policy, regardless of cost. Combining the analysis results, we demonstrated that some expenses could not be recovered as merchant discount revenue when the related expenses rose due to the increase in card usage amount. To fix the structural problem of the card payment business, we suggest changing the preferential commission rates according to market conditions, reflecting eligible costs in member recruitment costs, reflecting adjustment costs in the loss rate due to the application of preferential merchant discount rates, and excluding the decrease in cost ratio due to management efficiency when the merchant discount rate is re-adjusted.
Dengue, chikungunya and Zika virus infections among Dutch travellers to Suriname: a prospective study during the introduction of chikungunya and Zika virus, 2014 to 2017
Authors: Overbosch Femke W , Schinkel Janke , Matser Amy , Koen Gerrit , Prange Irene , Prins Maria , Sonder Gerard JB
Published: January 2023

Background

Suriname, a country endemic for dengue virus (DENV), is a popular destination for Dutch travellers visiting friends and relatives and tourist travellers. Chikungunya and Zika virus (CHIKV, ZIKV) were introduced in 2014 and 2015, respectively. Data on infection risks among travellers are limited.

Aim

We aimed to prospectively study incidence rate (IR) and determinants for DENV, ZIKV and CHIKV infection in adult travellers to Suriname from 2014 through 2017.

Methods

Participants kept a travel diary and were tested for anti-DENV, anti-ZIKV and anti-CHIKV IgG antibodies (Euroimmun). Selected samples were subjected to an in-house DENV and ZIKV PRNT50. The IR (infections/1,000 person-months of travel) and IR ratio and determinants for infection were calculated.

Results

Travel-acquired infections were found in 21 of 481 participants: 18 DENV, four ZIKV and two CHIKV, yielding an IRDENV of 47.0 (95% CI: 29.6–74.6), IRZIKV of 11.6 (95% CI: 4.4–31.0) and IRCHIKV of 5.6 (95% CI: 1.4–22.2)/1,000 person-months. In nine DENV and three ZIKV infected participants, infections were PRNT50-confirmed, yielding a lower IRDENV of 23.3 (95% CI: 12.1–44.8) and an IRZIKV of 8.4 (95% CI: 2.7–26.1) per 1,000 person-months. Tourist travel was associated with DENV infection. ZIKV and CHIKV infections occurred soon after their reported introductions.

Conclusions

Despite an overestimation of serologically confirmed infections, Dutch travellers to Suriname, especially tourists, are at substantial risk of DENV infection. As expected, the risk of contracting ZIKV and CHIKV was highest during outbreaks. Cross-reaction and potential cross-protection of anti-DENV and -ZIKV antibodies should be further explored.

Effect of Substitution of Cement by Mineral Powders on the Physicomechanical Properties and Microstructure of Sand Concretes
Authors: Belhadj Belkacem , Houessou Justin , Montrelay Nicolas , Quéneudec Michèle
Published: January 2023

The approach that contributes to the development of eco-materials in construction is the use of mineral powders, which can improve mechanical properties and reduce cement consumption. This article aims to study the effect of substitution by mass of cement with mineral powders on the physicomechanical properties and microstructure of sand concretes. The used mineral powders are A: the limestone, B: the natural pozzolan, C: the hydraulic lime, D: (1/3 limestone + 1/3 natural pozzolan + 1/3 hydraulic lime), and E: (1/2 natural pozzolan + 1/2 hydraulic lime). The studied percentages are 5%, 10% and 15%, in both separated and combined states. The studied properties are workability, compressive strength, the elasticity modulus in compression, shrinkage and microstructure analysis. The objective is to target the optimal percentage of the substitution of cement with mineral powders, which ensures the best compromise between the main properties of the studied sand concretes. The obtained results show that the optimal percentage is in favor of the substitution of cement by 10% D (1/3 limestone, 1/3 natural pozzolan and 1/3 hydraulic lime). Even the 15% of mineral powder D, presented similar performances compared to the sand concrete (without mineral powders). Finally, in the context of the development of eco-materials, it should be noted that the 10% D and 15% D (1/3 limestone, 1/3 natural pozzolan and 1/3 hydraulic lime) contribute to decrease the use of cement and consequently to reduce of CO2 emissions.
Criticising Change: From Theognis to Plato
Authors: De Martin Sara
Published: January 2023

This paper examines how socio-political and cultural change is discussed in selected archaic and classical Greek texts (Thgn. 53-60, 287-92; Pherecr. fr. 155 K.-A.; Aristoph. Nub. 889-1023; Pl. Lg. 700a-701c). The analysis underlines the thematic, rhetorical and stylistic features and the moral preoccupations that are common to these sources. It is then argued that they all participate in an intertextual ‘discourse on change’. Furthermore, the article samples how close textual readings can be enhanced by the awareness that each single passage, as an instance of this tradition of discourse, is intertextually connected to the others.

The aim of this paper is to provide a new analysis of four latin fragments preserved on the verso of P. Gen. inv. Lat. 7 (2nd century AD). They have often been considered as an inventory of works of art linked to P. Gen. inv. Lat. 5, but content and palaeographical evidence indicate that they are two different texts. These four fragments contain two texts of mythographic content concerning Roman divinities and heroes, Egyptian mythology (the presence of Isis, Horus and Aegipan suggests a reference to episodes of the myth of Osiris), mutations of divinities and religious mysteries of Persephon, mentioned together with divinities and demigods traditionally linked to the underworld.
For a Pre-history and Post-history of the Corpus Leidense
With a List of the Manuscripts of De natura deorum
Authors: Bailo Anna , Malaspina Ermanno
Published: January 2023

The present article examines the Corpus Leidense, the group of eight
Ciceronian treatises among which the De natura deorum was also transmitted, focusing
on its archetype. The second and longer section contains the first complete list of
the 174 identified manuscripts of De natura deorum, with 57 new items added to the 117
already listed by Pease in 1955. The items have been divided into three groups: the first
contains the antiquiores, with minimal information; the second contains the remaining
witnesses listed by Pease, on which additional data are reported; the third group presents
the manuscripts that do not appear in any previous list.
APl 62-63 Allegedly on an Equestrian Statue for Justinian
Authors: Gullo Arianna
Published: January 2023

This article treats two anonymous epigrams (APl 62-3) preserved in the so-called
Anthologia Planudea which, according to the lemma, were both inscribed on the
same equestrian statue of the emperor Justinian I placed in the Hippodrome of Constantinople.
Scholars have identified this statue with the one dedicated after a Persian
victory and still surviving in the 8th century CE. The paper argues that not only do the two
poems concern two different and separate objects, but also that just APl 63 could refer
to a statue (and not necessarily the famous one accepted by most scholars), whereas APl
62 seems to allude to a smaller object belonging to the category of imperial luxury gifts.

A Educação Matemática convencional, na maioria das vezes, priva os discentes de desenvolverem habilidades importantes para a atuação na sociedade do século XXI como a autonomia, a criatividade e o senso crítico. O ensino através da Resolução de Problemas se configura como uma possibilidade para sanar as rupturas no ensino convencional da Matemática. Com o objetivo de analisar como o ensino através da Resolução de problemas influencia na autonomia dos estudantes, foi realizada uma pesquisa com 35 estudantes do 3o ano do Ensino Médio de uma Escola Estadual Pública localizada na cidade de Patos, na Paraíba Como resultados, podemos verificar que essa metodologia instiga os estudantes a agir de maneira autônoma, colocando estes como protagonistas na construção de seu próprio conhecimento, visto que os estudantes raciocinaram, acionaram seus conhecimentos prévios e organizaram suas ideias a fim de produzirem soluções pessoais para os problemas aplicados.

Coal combustion by-products, such as coal fly ash, has known as a significant source of potentially toxic elements that may affect the environment since the increase of coal utilization as power fuel in Indonesia. Issuing the policies to protect the environment and public health is often based on analytical results. The quality of data analysis is very important since many crucial policies related to public health and environmental protections are based on the analytical results. Considering the need for reference material in ensuring the validity and reliability of the analytical results, reference material candidate of coal fly ash is being developed. Elemental characterization as one of the important parts in certifying the reference material is carried out using Neutron Activation Analysis (NAA) since it considered as high accuracy analytical method and commonly used to certified many reference materials throughout the world. Our NAA facility performance was assessed through optimizing analytical conditions by varying samples weight, method validation, and comparison test with other techniques as well. As much as 25, 100, and 250 mg of sample weight were assessed for its homogeneity effect. Method validation using SRM NIST 1633b had shown good results with bias not more than 10% compared to its certificate values. A comparison test with other results also showed a great agreement.

 
METODE PENENTUAN UMUR FUNGSIONAL SELANG KOMPOR GAS LPG

Published: January 2023

Kebocoran selang karet atau elastomer Liquefied Petroleum Gas (LPG)merupakan penyebab utama kebakaran berdasarkan penelitian-penelitian sebelumnya. Hal ini disebabkan belum adanya pencantuman masa kadaluarsa (umur fungsional) selang LPG dalam SNI 7213:2014. Pencantuman umur fungsional selang LPG membutuhkan pendekatan perhitungan umur fungsional. Baik standar internasional, standar nasional, dan tataran ilmu pengetahuan belum membahas ranah ini atau menentukan pendekatan perhitungan umur fungsional selang LPG. Penelitian ini bertujuan mengusulkan metode penentuan umur fungsional khusus untuk produk selang LPG, dengan mempertimbangkan segala aspek penggunaan dari produk tersebut. Metode yang digunakan adalah eksploratif deskriptif dengan kombinasi metode Arrhenius dan metode dalam SNI sebagai titik tolak. Hasilnya diperoleh 3 pendekatan, yaitu: 1) Pendekatan metodeArrhenius, 2) Pendekatan sampel tidak terkondisi, dan 3) Pendekatan sampel terkondisi. Peneliti menyarankan bahwa metode pendekatan sampel tidak terkondisi sangat sesuai digunakan jika variasi selang LPG cukup tinggi karena memerlukan waktu yang relatif cepat, sampel yang mencerminkan kondisi sebenarnya dan biaya yang tidak mahal, adapun metode Arrhenius1 dan metode pendekatan sampel terkondisi lebih cocok digunakan ketika produk sebelum dilepas ke pasar.

Kereta commuter line merupakan sarana transportasi yang banyak digunakan saat ini, khususnya di daerah Jakarta, Bogor, Depok, Tangerang, dan Bekasi (Jabodetabek). Jumlah penumpang yang banyak ternyata tidak didukung dengan jumlah tempat duduk yang seimbang. Oleh karena itu, ketersediaan pegangan tangan (handgrip) sangat diperlukan dalam menjaga keseimbangan penumpang dengan posisi berdiri khususnya saat kereta commuter line sedang berjalan. Ketersediaan pegangan tangan yang berkualitas menjadi harapan setiap penumpang berdiri. Namun yang tersedia saat ini belum cukup memenuhi kebutuhan dari penumpang. Untuk mengatasi hal tersebut, pengembangan standar pegangan tangan pada kereta commuter line sangat diperlukan. Maka penelitian ini bertujuan untuk melakukan analisis kebutuhan konsumen dalam pengembangan standar pegangan tangan pada kereta commuter line. Penelitian dibagi menjadi dua tahap. Pertama, identifikasi kondisi terkini dari pegangan tangan yang tersedia berdasarkan pandangan konsumen. Kedua, konfirmasi parameter yang akan dikembangkan berdasarkan kondisi terkini yang diperoleh pada tahap pertama menggunakan skala Likert. Pengambilan data dilakukan secara purposive sampling terhadap penumpang kereta api pada kedua tahapan yang dilakukan. Hasil penelitian diperoleh kondisi pegangan tangan yang ada berdasarkan pandangan konsumen, dan diperoleh tujuh (7) persyaratan yang akan dikembangkan sesuai dengan kebutuhan konsumen. Persyaratan tersebut menjadi rekomendasi dalam pengembangan standar pegangan tangan pada kereta commuter line sesuai dengan kondisi di Indonesia. Sehingga standar yang dihasilkan mampu diaplikasikan dengan baik dan memberikan keselamatan dan kenyamanan bagi penumpang kereta commuter line.

SNI 09-4663-1998 dianggap telah tidak memenuhi perkembangan produk sehingga perlu dilakukan pengkajian ulang yang diawali dengan mengukur kemampuan pasar dan produsen. Penelitian ini melakukan pengujian parameter kekuatan meliputi kekuatan statis, impact, dan fatik yang menjadi usulan parameter utama SNI, serta menjadi parameter yang berkaitan erat dengan keamanan dan keselamatan pengguna. Pengujian menggunakan 5 sampel, terdiri dari 2 produk dalam negeri dan 3 produk impor yang banyak ditemui di pasaran. Prosedur dan spesifikasi pengujian mengacu pada ISO 7176-8 dan dilakukan di laboratorium PT Mega Andalan Kalasan (terakreditasi SNI ISO/IEC 17025:2017). Hasil penelitian menunjukkan bahwa seluruh sampel dapat memenuhi uji kekuatan statis dengan 3 sampel membutuhkan perbaikan pada tipping lever. Pada pengujian stabilitas statis, 80% sampel dapat memenuhi standar. Sedangkan untuk uji fatik rem dapat dipenuhi oleh semua sampel, namun semua sampel tidak dapat memenuhi uji jatuh. Siklus tertinggi untuk uji jatuh yang tercapai, yaitu 2000 siklus oleh produk impor dan 1500 siklus oleh produk dalam negeri. Sedangkan untuk uji multidrum, hanya 50% dapat memenuhi uji dan 1 sampel tidak dapat dapat mengikuti uji multidrum karena mengalami deformasi pada uji jatuh. Kondisi semua sampel tidak dapat memenuhi uji jatuh. Uji Jatuh pada ISO 7176-8 dapat dijadikan syarat uji dengan pertimbangan mempersiapkan kemampuan produsen dalam negeri sehingga selain dapat menguasai pasar lokal dan produk dalam negeri dapat menjangkau pasar ekspor. Tipping lever dapat diusulkan menjadi salah satu syarat di SNI karena merupakan keunggulan produk dalam negeri dan mendukung keamanan pengguna kursi roda.
