Emerging maritime cyber threats put Indonesia's marine technology-based systems at risk This study aims to determine the dimensions and analysis of risk assessment in maritime cyber security based on 3D models in the Indonesian sea area. A statistical descriptive qualitative method approach supported by the Analytical Hierarchy Process (AHP) and Technique for Order by Similarity to Ideal Solution (TOPSIS) methods were used in this study. Risk analysis in maritime cybersecurity has 3 (three) main criteria: Threat, Vulnerability, and consequence. Based on the results of 3D risk analysis, the six dimensions of MCS are identified as having a level of risk at Very Low and Low Risk. The highest risk value is obtained by the dimension of Cyber security-related company procedures (D2) (0.368) and the lowest risk value is Ship's systems readiness (D3) (0.048).
新兴的海上网络威胁使印度尼西亚的海洋技术系统面临风险本研究旨在确定基于印度尼西亚海域3D模型的海上网络安全风险评估的维度和分析。本研究采用层次分析法(AHP)和理想解相似性排序法(TOPSIS)支持的统计描述性定性方法。海上网络安全风险分析有3个主要标准:威胁、脆弱性和后果。基于三维风险分析的结果,MCS的六个维度被确定为具有非常低和低风险的风险水平。风险值最高的是网络安全相关公司流程维度(D2)(0.368),风险值最低的是船舶系统就绪度维度(D3)(0.048)。

In 2019, the COVID-19 epidemic swept throughout the globe. The virus was first identified in Wuhan, China. By the time several months had gone by, this virus had spread to numerous locations throughout the world. Consequently, this virus has become a worldwide pandemic. Multiple efforts have been made to limit the transmission of this virus. A possible course of action is to lock down the territory. Unfortunately, this strategy wrecked the economy, worsening the terrible situation. The world health organization (WHO) would breathe a sigh of relief if there were to be no new cases. However, the government should explore employing data from the future in addition to the data it already has. Prediction of time series may be utilized for this purpose. This study indicated that the Gaussian processes method outperformed the least median squared linear regression method (LMSLR). Applying a Pearson VII-based global kernel produces MAE and RMSE values of 23.12 and 53.43, respectively.
2019年,新冠肺炎疫情席卷全球。该病毒最初是在中国武汉发现的。几个月过去了,这种病毒已经传播到世界各地的许多地方。因此,这种病毒已成为世界性的大流行病。为限制这种病毒的传播,已作出多项努力。一个可能的行动方针是封锁领土。不幸的是,这一策略破坏了经济,使糟糕的形势进一步恶化。如果没有新的病例,世界卫生组织(世卫组织)将松一口气。但是,除了现有的数据之外,政府应该探索利用未来的数据。时间序列的预测可用于此目的。研究表明,高斯过程方法优于最小中位数平方线性回归方法(LMSLR)。应用基于Pearson vii的全局核得到的MAE和RMSE值分别为23.12和53.43。

It is not a secret that road accidents cause significant suffering. Those accidents can last from wounded to dead people, negatively impacting a country. A bunch of recent investigations tried to tie road accidents with the quality of roads. Therefore, in a country with a significant infrastructure gap, it is necessary to analyze the relationship between the different kinds of roads and the severity of car accidents. The current research examined such a relationship by employing the Multi logit regression. It was found that the significance of different car accidents will vary among the road types. Moreover, with the help of probability analysis, it was discovered that speeding, emergency services availability, and road security seemed to have a crucial impact on road accidents.
众所周知,交通事故会带来巨大的痛苦。这些事故可能从受伤到死亡,对一个国家产生负面影响。最近的一些调查试图将交通事故与道路质量联系起来。因此,在一个基础设施差距很大的国家,有必要分析不同类型的道路与车祸严重程度之间的关系。目前的研究采用多元逻辑回归来检验这种关系。研究发现,不同道路类型对不同交通事故的影响程度不同。此外,在概率分析的帮助下,发现超速、应急服务的可用性和道路安全似乎对道路事故有至关重要的影响。

This research conducted testing on the influence of business strategy, leadership style, and internal control system (IC) on implementation of Good Government Governance (GGG) and its implication on organizational performance of Social Security Administrator for Health (known as BPJS Kesehatan). Data analysis was performed using a descriptive method, assisted by a statistical tool Structural Equation Modeling (SEM)-Lisrel. The data was tabulated from distributed and returned questionnaires from 325 deputy offices, branch offices, and service offices. The results showed that business strategy, leadership style, and the effectiveness of IC influenced the implementation of Good Government Governance. The result also provides evidence that leadership style had a positive significant influence on performance. Conversely, the business strategy and effectiveness of IC did not have a positive significant influence on BPJS performance.

Traditionally, endemic diseases such as dengue, diarrhea, and tuberculosis are modeled separately, which leads to a limited understanding of current disease dynamics and an inaccurate evaluation of the parameters of the different models. In this study, we propose a joint spatiotemporal model to predict the risks of multiple endemic diseases and identify hotspots. The model includes spatial shared component random effects and a covariate for healthy behavior. The model was applied to the joint modeling of dengue, diarrhea, and tuberculosis in thirty districts in Bandung, Indonesia over a five-year period. Our findings show that the joint model was effective in understanding the characteristics of the diseases. One potential advantage of using shared component models is that they can identify diseases with spatial or temporal distribution patterns and consider shared risk factors that may be spatially correlated, such as climate. It is recommended to conduct exploratory analyses to determine the correlation between the risks of the diseases being studied and the reference disease before using this type of model.
传统上,登革热、腹泻和结核病等地方病是单独建模的,这导致对当前疾病动态的理解有限,对不同模型参数的评估也不准确。在这项研究中,我们提出了一个联合的时空模型来预测多种地方病的风险和识别热点。该模型包括空间共享分量随机效应和健康行为协变量。该模型被应用于印度尼西亚万隆30个地区为期5年的登革热、腹泻和结核病联合模型。我们的研究结果表明,关节模型在理解疾病特征方面是有效的。使用共享成分模型的一个潜在优势是,它们可以确定具有空间或时间分布模式的疾病,并考虑可能在空间上相关的共同风险因素,如气候。建议在使用这类模型之前进行探索性分析,确定所研究疾病的风险与参考疾病之间的相关性。

The construction of smart villages has begun in many Indonesian villages, along with the advancement of technology and local economic growth. Villagers must participate in constructing the smart economy-smart village by becoming familiar with the characteristics of the village's inhabitants using the citizen science model. This study intends to categorize villagers so that researchers can assess and decide their level of readiness for a smart economy in an ecosystem based on a smart village. Clustering is required to find communities of residents who are ready based on their traits. Using fuzzy C-Means with a Davied Bouldin Index value of 0.129, the data were divided into 4 clusters. The most important variables were chosen using information from the test's 300 responders, and the Kaiser Mayer Olkin assumption of 0.975 was used to validate the results. Our paper provides new information on how smart village readiness is assessed by the citizen science cluster. It was decided to divide residents into four groups: those who are less prepared (24.33%), those who are somewhat prepared (29.33%), those who are ready ( 25.67%) %), those who are ready (level of participatory knowledge), and those who are very ready for the smart economy (20.67%) based on the cluster model.
随着科技的进步和当地经济的发展,智慧村庄的建设已经在印度尼西亚的许多村庄开始。村民必须运用公民科学模型,通过熟悉村民的特点,参与智慧经济-智慧村的建设。本研究旨在对村民进行分类,以便研究人员能够评估和决定他们在基于智慧村庄的生态系统中对智能经济的准备程度。需要聚类来找到根据他们的特征准备好的居民社区。采用david Bouldin指数为0.129的模糊C-Means将数据分为4类。最重要的变量是使用测试的300个应答者的信息来选择的,并且使用0.975的Kaiser Mayer Olkin假设来验证结果。我们的论文提供了关于公民科学集群如何评估智慧村准备情况的新信息。根据聚类模型,决定将居民分为“准备不足”(24.33%)、“有一定准备”(29.33%)、“准备好”(25.67%)、“准备好”(参与知识水平)、“非常准备”(20.67%)等4个群体。

This study investigates how audit quality moderates the effect of financial performance indicators on the stock returns of Amman Stock Exchange-listed firms (ASE). The panel data analysis selected the data of 95 ASE-listed firms from 2013 through 2021. This analysis demonstrates a significant inverse relationship between a company's book value and its stock returns. A statistically negative relationship was observed between cash flow, dividends per share, and stock return. The empirical results of this study confirm the moderating influence of audit quality in the relationship between financial performance and stock return. Firstly, auditor's fees have a significant impact on the relationship between firm stock returns and EPS, BV, DPS, and cash flows (CFO). The size of the auditing firm moderates the relationship between company stock returns and EPS, DPS, and the CFO, but not with book value (BV). The auditor's opinion moderates the relationship between business stock returns and EPS, BV, and DPS but not the relationship between firm stock returns and cash flows (CFO). The study suggests that regulatory bodies like the Companies Control Department (CCD) and ASE should make sure that local audit firms in Jordan improve their audit quality to be on par with the Big 4 audit firms in order to improve their financial performance measures and stock returns.
本研究探讨审计质量如何调节财务绩效指标对安曼证券交易所上市公司(ASE)股票收益的影响。面板数据分析选取了2013 - 2021年95家ase上市公司的数据。这一分析表明,一家公司的账面价值与其股票收益之间存在显著的反比关系。现金流、每股股利与股票收益呈负相关。本研究的实证结果证实了审计质量在财务绩效与股票收益关系中的调节作用。首先,审计师费用对公司股票收益与每股收益、账面价值、每股收益和现金流量(CFO)之间的关系有显著影响。审计事务所的规模调节了公司股票收益与每股收益、每股收益和首席财务官之间的关系,但对账面价值(BV)没有调节作用。审计意见调节了企业股票收益与每股收益、账面价值和每股收益之间的关系,但没有调节公司股票收益与现金流量(CFO)之间的关系。该研究建议,公司控制部(CCD)和ASE等监管机构应确保约旦当地审计公司提高审计质量,使其与四大审计公司持平,以改善其财务绩效指标和股票回报。

Tracking abundant gene transcripts quantification over continuous cancer progression stages may reveal the mechanism of disease advancement. In this work, we profile the transcript quantification over the stages using a time-series approach, in which the stages/sub-stages of the disease are the time points, and the quantification measurements are the values. The values over time points are used to interpolate the growth of the progression using the cubic spline function. Then, the transcripts profiles are universally aligned and clustered using the time-series profile hierarchical clustering method based on the area between each pair of the aligned profiles; the method is named (HC-UAP). We compare the proposed method with a hierarchical clustering method based on Euclidean distance (HC-ED). Both methods were applied on two next-generation sequencing (NGS) prostate cancer datasets, the first from the Chinese and the second from the North American population. HC-ED clusters the dataset to find patterns while HC-UAP was able to single out outliers that trend differently in both datasets. While finding patterns in gene expression that trend over stages is the standard approach for analyzing time-series models, identifying outlier transcripts that grow differently than other transcripts can provide more details about the contribution of the mRNA transcriptional activity to the disease. They also can be a potential biomarker for the disease progression.
在连续的癌症进展阶段跟踪丰富的基因转录物定量可能揭示疾病进展的机制。在这项工作中,我们使用时间序列方法对各阶段的转录本量化进行了分析,其中疾病的阶段/亚阶段是时间点,量化测量是值。随时间点的值用于使用三次样条函数插值级数的增长。然后,利用时间序列序列分层聚类方法对转录本图谱进行全局对齐和聚类;该方法被命名为(HC-UAP)。我们将该方法与基于欧几里得距离(HC-ED)的分层聚类方法进行了比较。这两种方法都应用于两个下一代测序(NGS)前列腺癌数据集,第一个来自中国,第二个来自北美人群。HC-ED对数据集进行聚类以发现模式,而HC-UAP能够挑出两个数据集中趋势不同的异常值。虽然发现基因表达在各个阶段的趋势模式是分析时间序列模型的标准方法,但识别与其他转录物生长不同的异常转录物可以提供更多关于mRNA转录活性对疾病贡献的细节。它们也可能是疾病进展的潜在生物标志物。

Then, the transcripts profiles are universally aligned and clustered using the time-series profile hierarchical clustering method based on the area between each pair of the aligned profiles; the method is named (HC-UAP). We compare the proposed method with a hierarchical clustering method based on Euclidean distance (HC-ED). Both methods were applied on two next-generation sequencing (NGS) prostate cancer datasets, the first from the Chinese and the second from the North American population. HC-ED clusters the dataset to find patterns while HC-UAP was able to single out outliers that trend differently in both datasets. While finding patterns in gene expression that trend over stages is the standard approach for analyzing time-series models, identifying outlier transcripts that grow differently than other transcripts can provide more details about the contribution of the mRNA transcriptional activity to the disease. They also can be a potential biomarker for the disease progression.","PeriodicalId":38141,"journal":{"name":"Decision Science Letters","volume":"5 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81254453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MEWMA chart is one of the traditional multivariate charts which are widely employed in inspecting the quality of manufacturing and services. This chart is created through monitoring the small shifts of mean vectors of variable quality characteristics. Often in practice, the measurement of a quality characteristic produces uncertain, incomplete values, so that ambiguous numbers are obtained. In this condition, a neutrosophic-based control chart can overcome the problem resulting from the ambiguous data. The paper’s objective is to construct a new multivariate monitoring scheme based on a neutrosophic chart, namely the neutrosophic Multivariate EWMA (NMEWMA). Furthermore, the performance of the new multivariate monitoring scheme is evaluated in detecting process shifts employing the Average Run Length (ARL) and Standard Deviation Run Length (SDRL). This control chart is an innovation in the quality monitoring of uncertain data. The research result obtained indicates that the NMEWMA chart performs better than the MEWMA in finding the small mean shifts as well as in the real case application.
MEWMA图是一种传统的多变量图,广泛应用于制造业和服务业的质量检验。这个图表是通过监测可变质量特征的平均向量的小位移而创建的。通常在实践中,对质量特性的测量会产生不确定的、不完整的值,从而得到模棱两可的数字。在这种情况下,基于中性粒细胞的控制图可以克服数据模糊的问题。本文的目的是构建一种新的基于嗜中性图的多变量监测方案,即嗜中性多变量EWMA (NMEWMA)。此外,利用平均运行长度(ARL)和标准偏差运行长度(SDRL)评估了新的多变量监测方案在检测过程位移方面的性能。这种控制图是对不确定数据进行质量监测的一种创新。研究结果表明,NMEWMA图在寻找小均值偏移和实际应用中都优于MEWMA图。

The proliferation of artificial intelligence (AI) has emerged as a critical metric for assessing a country's technological advancement, but also for regional economic coordination and high-quality development in China. Based on panel data collected from 31 provinces between 2006 and 2021, this study employs the DEA-Malmquist index model and panel Tobit model to examine the scale, distributional attributes, and influencing factors of AI resource allocation. Results indicate that China's AI resource allocation efficiency has generally increased, with technical efficiency generating a “pull effect” that propels total factor productivity growth rates higher than those attributable to technological progress. Furthermore, AI efficiency in non-coastal regions outstrips that in coastal areas, with total factor productivity growth arising from a substantial increase in technological progress rates. Regional economic development, labor demand, openness to foreign participation, and human capital level exert pivotal roles in enhancing AI resource allocation efficiency. Based on these findings, we suggest a set of strategies aimed at enhancing China's AI resource allocation efficiency, including amplifying government guidance, increasing R&D investments, upgrading economic development levels, fostering the development and strengthening of tangible economy, and attracting and nurturing high-quality scientific research talent.
人工智能(AI)的扩散已经成为评估一个国家技术进步的关键指标,也是中国区域经济协调和高质量发展的关键指标。基于2006 - 2021年中国31个省份的面板数据,采用DEA-Malmquist指数模型和面板Tobit模型,考察了中国人工智能资源配置的规模、分布属性及其影响因素。结果表明,中国人工智能资源配置效率总体提高,技术效率产生“拉动效应”,推动全要素生产率增速高于技术进步。此外,非沿海地区的人工智能效率超过沿海地区,全要素生产率的增长源于技术进步速度的大幅提高。区域经济发展、劳动力需求、对外开放程度和人力资本水平对提高人工智能资源配置效率起着举足轻重的作用。基于这些研究结果,我们提出了一套旨在提高中国人工智能资源配置效率的策略,包括加大政府引导、增加研发投入、提升经济发展水平、促进有形经济的发展和加强、吸引和培养高素质的科研人才。
