"Blank" and Love: Love in the Miniature Novels of Indonesian--Chinese Writer Yuan Ni
Authors: Jiatong Wang
Published: November 2022

Among Indonesian-Chinese authors, Yuan Ni is very well known. This paper analyzes her miniature novels by using Wolfgang Iser’s blank theory to explore her writing on love and the values behind it. Firstly, Yuan Ni’s view of love shows a call for genuine feelings, and the artistic blank in some of her novels leads readers to think critically. Secondly, her novels also show the notion that perfect love should be sublimated in the family, which is the result of Indonesian-Chinese women’s conscious identification with traditional Chinese ethics. The concept of family is an important point in this traditional ethical view. However, in some of her works, the novel presents blank the meaning of the text, which reflects the fact that the family, a symbol of patriarchal power, often hinders love, and this feature of the text reveals the author’s inner entanglement.

Authors: Yiming Zhang , Yu Lu , Yuli Fan , Songhan Jia
Published: November 2022

In the current global context, with prominent multilateralism and multipolarity trends, China is seeing a rise in comprehensive strength and influence on the international stage. China has always upheld mutual respect, mutual benefits, and win-win situations for its diplomatic strategies and has launched the Belt and Road Initiative to actively unite neighboring countries and regions for common development and advancement. Person-to-person diplomacy is an important part of foreign affairs work, of which overseas Chinese are a force to be reckoned with. Overseas Chinese are also descendants of the Chinese nation, so it is easier to communicate with them concerning culture, language, characters, and ideas. Therefore, with Chinese in Indonesia as the research subjects, this paper provides a case study of the Confucius Institute jointly built by Xihua University and Universitas Sebelas Maret (Sebelas Maret University, UNS) to specifically explore how to expand person-to-person diplomacy, unite overseas Chinese, promote China-foreign exchanges and cooperation, and enhance mutual understanding and friendship between the two peoples with overseas Chinese as the bridge.

Published: November 2022

Various environmental issues have attracted the attention of many parties, including manufacturing companies. This encourages manufacturing companies to implement green manufacturing into their business operations. Implementation of green manufacturing is not easy to do. For this reason, companies must have the capability to be able to adapt to the rapidly changing business environment. This paper discusses how the green dynamic capability affects the implementation of green manufacturing in manufacturing companies. The study was conducted on 34 manufacturing companies regardless of their industrial sector. The research model describes the relationship between green manufacturing, green dynamic capabilities, and absorptive capacity. The results of model testing (measurement models and structural models) showed that green dynamic capability has a positive and significant effect on green manufacturing practices in manufacturing companies. Absorptive capacity directly affects green dynamic capability, and indirectly affects green manufacturing. This shows that the green dynamic capability plays an important role in the implementation of green manufacturing and must be a concern for the company’s management, especially in the implementation of green manufacturing.

Overview of the Relationship between Creative Teaching and Learning Method and Self-Esteem in Students Learning Mathematics
Authors: Permanasari Y. , Fajar M. Y. , Rohaeni O. , Suhaedi D. , Harahap E. H.
Published: November 2022

Thinking differently refers to a person’s ability to come up with ideas to solve problems and logical thinking is a person’s ability to verify these ideas into creative solutions. The ability to logically solve problems can be developed by learning mathematics, because mathematics has a strong linkage structural between its concepts that enables students to think logically, critically, and systematically. Creative thinking is very important in this competitive millennial era, where the quality of education is closely related to creativity so efforts to improve creative thinking should start from school. Senior high school students are the main millennials, so high school and equivalent teachers are required to be able to provide education that provides an initial description of creative thinking. Learning innovation through lessons with the Creative Teaching and Learning (CTL) method for high school mathematics teachers and the equivalent can encourage teachers to improve cognitive and didactic pedagogic abilities as well as increase the self-esteem of students in learning mathematics.

Authors: . Suharno , Sulaeman Maman , Ahmad Abdul Aziz
Published: November 2022

The prevalence of stunting over the past 10 years indicates no significant changes and this indicates that the stunting problem needs to be addressed immediately. The indirect cause of the problem of stunting is influenced by various factors including the health budget, fiscal autonomy, and the level of poverty. This study used a regression model using panel data or pooled data (pooling cross section-time series regression). The cross-section unit was 100 districts and cities in 33 provinces in Indonesia and the year of analysis in 2019. The analysis showed that, partially, the level of poverty influences the incidence of stunting, the health budget influences the incidence of stunting, and fiscal autonomy influences the incidence of stunting. Simultaneously the health budget, fiscal autonomy, and poverty level influence stunting. Our study recommends that the Indonesian government increase health budget, reduce the inter-regional fiscal gap, improve the social welfare of the Indonesian people, and reduce revenue inequality.

Carbon Sequestration Potential in Coconut based Cropping System: A Review
Authors: Namitha V.V. , Raj Sheeja K. , Prathapan K.
Published: November 2022

Carbon sequestration plays a significant part in alleviating climate change by changing over climatic carbon as plant biomass and soil organic carbon. Since trees can hold greater carbon in their biomass than other plant types, perennial plantations have a vital function in mitigating the adversities in climate. Coconut is a perennial palm with a life time of around 50-60 years has the capability to store carbon for a long time, especially in the stem. Due to the increased availability of space and solar radiation reaching the understorey, the carbon sequestration capacity of coconut plantations can be considerably increased. As a result, intercropping or agroforestry in coconut lands is important not only for food and economic security but also for carbon sequestration. On an average carbon sequestration potential of coconut trees range between 37 kg tree-1 yr-1 (dwarf variety) up to 56 kg tree-1yr-1 (tall variety). After 20 years of establishment, monoculture coconut land can be transformed into perennial mixed cropping or agroforestry system that can sequester more carbon.
International Evidence On Currency Adjusted Stock Indexes
Authors: Jalbert Terrance
Published: November 2022

Recent literature examines currency value adjusted indexes. The extant research examines U.S. stock indexes as adjusted for the value of the U.S. dollar and the value of gold. The literature examines only U.S. stock indexes. This paper extends the existing literature by examining currency adjusted stock indexes from eight countries. The analysis includes daily closing data from 1993-2016. The results show that currency adjusted indexes produce significantly different return distributions than original indexes. Further, currency value changes explain as much as 31 percent of total wealth changes, a result substantially higher than previously reported for U.S. currency adjusted indexes. The combined evidence indicates that currency value changes impact total wealth changes more for international indexes than for U.S. indexes.

Low Oxygen Tension Inhibits Senescence in Bone Marrow Mesenchymal Stem Cells (BMSCs)
Authors: Bumi Candra
Published: November 2022

Background: Stem cells have been used in regenerative medicine but are so few in the body that they require cell culture. Stem cell culture was performed under normal oxygen tension and passage was carried out until the number of cells was sufficient for therapy. Stem cell cultures under normal oxygen tension do not match the stem cell microenvironment, which can lead to premature senescence. This study aims to determine the association of low oxygen tension with premature senescence of mesenchymal stem cells (MSCs) through inhibition of p21 expression by HIF-1a. Methode: The research method used rabbit bone marrow in New Zealand as a source of MSCs. The results of isolation of MSCs were divided into two groups for cultured on normal and low oxygen tension until 10 passages. Cells were identified using flowcytometry for cd105 and cd34. At early and late passage, the expression of p21 and HIF-1a was examined using immunofluorescence while senescence was examined using β-galactosidase assay. Results: The results showed that in low oxygen cultures HIF-1a  expression increased significantly (p <0.05) while p21 expression decreased significantly (p <0.05) as did the β-galactosidase assay. Conclusions: The conclusion of this research is low oxygen tension culture able to decrease premature senescence culture of invitro stem cells mesenchymal through obstacles p21 by HIF-1a.

Keywords: p21 expression, HIF-1a expression, late passage, premature senescence.

Published: November 2022

Knowledge of the three-dimensional structure of proteins is very important to understand their character and function at the molecular level. Determination of protein structure in the laboratory is expensive and relatively difficult because it requires sophisticated instruments and takes a long time. As an alternative, an in silico approach can be used to predict the three-dimensional structure of proteins, namely the fold recognition method. The purpose of this study was to create a three-dimensional structure model of snakehead fish (Channa striata) calponin protein using the Phyre2 web server. The target protein sequence was obtained from UniProt KB with code K9LH64. The results of the study showed that the template for building the model was the c1wynA code. The results of the model (MP) evaluation obtained a coverage value was 45%, a confidence value was 100%, and an identity value was 69%. Validation of the model (MP) using the PROCHECK program showed the model was in the most favoured residue plot of 82.4%. This model deserves to be used as a model for calponin protein of snakehead fish, because the disallowed area was below 15%. The results of the analysis of interactions with other proteins using STRING-DB obtained the interaction model (MP) with Actin assembly-inducing protein (ACTA2) was 0.791; and Tropomyosin (TPM1) was 0.786. The results of molecular docking using PatchDock obtained the value of Atomic Contact Energy (ACE) for the calponin protein model (MP)-ACTA2 was 372.76 kJ/mol; Calponin model protein (MP)-TPM1 was 406.93 kJ/mol.

Computer networks are built to achieve the main goal of communicating with each other . During the transmission process, it is expected that information can be conveyed quickly, efficiently and safely. Network security serves to avoid damage or even data loss caused by attacker activities during the communication process. Security aspects that need to be maintained in data information are Confidentiality, Integrity and Availability. Intrusion Prevention System is a solution that can maintain network security from various attacks. The Intrusion Prevention System will act as a protector on the network by detecting and preventing suspicious traffic on nodes in a network. The Intrusion Prevention System in its implementation has several tools which are used in this study, namely Snort and IPTables. Testing is done by performing attacks on the Web Server. The attacks carried out are Port Scanning, DDoS attacks and Brute Force. The results of this study are based on the CIA Triad with the three attacks having different characteristics in terms of cause and effect. On the defense side, Port Scanning and Brute Force can be easily prevented by IPS, but in DDoS attacks there are differences in results between drop and reject rule. In a DDoS attack with an action drop rule, it can recover the web server in 160 seconds while the action reject rule can be restored at 145 seconds which normally can be recovered in a DDoS attack in 165 seconds. The IPS server can also reduce resources when there is a DDoS attack by 9.2% .

Published: November 2022

The prediction of rain duration based on data from the Meteorology, Climatology, and Geophysics Agency (BMKG) is an important issue but remains an open problem. At the same time, several studies have shown that missing values can cause a decrease in the performance of the model in making predictions. This study proposes k-nearest neighbors (KNN) imputation to overcome the problem of missing values in predicting rain duration. The source of the rain duration prediction dataset is the BMKG data. We compared gradient boosting regression (GBR), adaptive boosting regression (ABR), and linear regression (LR) for the regression model for predicting rain duration. We compared the KNN imputation method with several benchmark methods, including zero imputation, mean imputation, and iterative imputation. Parameters r2, mean squared error (MSE) and mean bias error (MBE) measure the performance of these imputation methods. The test results show that for rain duration prediction using the regression method, GBR shows the best performance, both for train data and test data with r2 = 0.915 and 0.776, respectively. Then our proposed KNN imputation has the best performance for missing value imputation compared to the benchmark imputation method. The prediction values of r2 and MSE when using KNN imputation at Missing Percentage = 90% are 0.71 and 0.36, respectively.
A Look to Model of Society and Teams Development based on Initial Formation, Primary, Adaptable, Information, and Creative Society Patterns
Authors: Gakh Dmitriy
Published: November 2022

There are different Maturity, Motivation, and Development models. The models can be applied to the development of organizations, businesses, information technology infrastructure, human resources, and so on. This paper discusses society patterns that can be used in modeling society and team development. The model discussed has many advantages over existing ones. It assumes the Age of Creativity and the Creative Society Pattern as the upmost level of development. The patterns are juxtaposed with the 16 levels Simple Learning Motivation Hierarchy Model that allow modeling of dynamic processes with Expansion and Totality as the upmost levels. This approach eliminates the limitations of existing models and allows detailed modeling and planning. Explanation of the future development of humanity (up to the Age of Creativity) is one of the advantages of the model. The paper contains the description of the main peculiarities of society patterns and creates a basis for practical implementation of the model for society and team development. Organizations and teams can benefit from this model through its implementation in consulting and coaching processes. The model can be used in regional/organizational development and investment planning.
Dynamically Updated Alive Publication Date
Authors: Gorbunov-Posadov Mikhail
Published: November 2022

The scientific work posted on the Internet, which its author constantly keeps up to date, will be called an alive publication. The genre of alive publishing has many attractive features. However, it requires a certain expansion of the composition of the meta-attributes of the publication: along with the traditional attributes, the date of the appearance of the new, fresh revision is brought to the fore here. Such date is placed in a prominent place in the text of the publication. Along with this, it becomes highly desirable to include such a dynamically ("on the fly") generated date in a bibliographic reference to an alive publication. The currently used methods of dynamic extraction of this date are considered for a simple online publication, for a publication that has received a DOI through Crossref, and for a publication posted in arXiv.org. Thanks to adding this meta-attribute, references to alive publications will beautify any bibliographic list.

Uncultured, unmodified, autologous, adipose-derived regenerative cells (UA-ADRCs) are a safe and effective treatment option for various musculoskeletal pathologies. However, it is unknown whether the composition of the final cell suspension systematically varies with the subject's individual age, sex, body mass index and ethnicity. UA-ADRCs were isolated from lipoaspirate from n=232 subjects undergoing elective lipoplasty using the Transpose RT system (InGeneron, Inc.; Houston, TX, USA). The UA-ADRCs were assessed for the number of nucleated cells, cell viability and the number of viable nucleated cells per gram of adipose tissue harvested. Cells from n=37 subjects were further characterized using four-channel flow cytometry. The present study shows, for the first time, that key characteristics of UA-ADRCs can be independent of the subject's age, sex, BMI and ethnicity. This result has important implications for the general applicability of UA-ADRCs in regeneration of musculoskeletal tissue. Future studies must determine whether in-dependence of key characteristics of UA-ADRCs of the subject's individual age, sex, BMI and eth-nicity only applies to the system used in the present study, or also to others of the more than 25 different experimental methods and commercially available systems used to isolate UA-ADRCs from lipoaspirate that have been described in the literature.
Multi-task Neural Network Blind Deconvolution and its Application to Bearing Fault Feature Extraction

Published: November 2022

Blind deconvolution (BD) is one of the effective methods that help pre-process vibration signals and assist in bearing fault diagnosis. Currently, most BD methods design an optimization criterion and use frequency or time domain information independently to optimize a deconvolution filter. It recovers weak periodic impulses related to incipient faults. However, the random noise interference may cause the optimizer to overfit. The time-domain-based BD methods tend to extract fault-unrelated single peak impulse, and the frequency-domain-based BD methods tend to retain the maximum energy frequency component, which will lose the fault-related harmonics frequency components. To solve the above issue, we propose a hybrid criterion that combines the kurtosis for time domain optimization and the $G-l_1/l_2$ norm for the frequency domain. These two criteria are monotonically increasing and decreasing, so they mutually constrain to avoid overfitting. After that, we design a multi-task one-dimensional convolutional neural network with time and frequency branches to achieve an optimal solution for this hybrid criterion. The multi-task neural network realizes the simultaneous optimization of two domains. Experimental results show that our proposed method outperforms other state-of-the-art methods.

Background: Acute pancreatitis is a common emergency. Morbidity control requires early detection of disease severity. METHODS: A total of 131 AP patients were analyzed retrospectively. Patients were divided into two groups mild AP (MAP: Ranson score <3) and severe AP (SAP: Ranson score ≥3), according to Ranson’s criteria. Demographic data, hospitalization duration, PNI, CRP, and RDW levels were compared. Any p-value below 0.05 (p<0.05) was accepted as statistically significant. RESULTS: Study included 67 (51.15%) males and 64 (48.85%) females. The age average was 59.74 (19-90) years. 95 (72.52%) patients had MAP, and 36 (27.48%) patients had SAP. Mean hospitalization time, PNI, and CRP differed significantly between the two groups (p=0.010, p<0.05, p<0.05, respectively). The RDW (p=0.380) level difference was insignificant. For SAP prediction; the sensitivity, specificity and cut-off value according to Ranson code cut-off point for PNI were determined as 80.0% (95% CI:54.8-85.8), %72.2 (95% CI:70.5-87.5) and ≤45.6 (gr/L) + (mm3), respectively, and 94.7% (95% CI:57.8-87.9), %75.0 (95% CI:88.1-98.3) and >105,1 mg/L, respectively for CRP. CONCLUSION: PNI and CRP values (but not RDW values) were compatible with the disease severity determined by the Ranson criteria.
