The existence or presence of micro, small and medium enterprises (“UMKM”) has an economic, social, and political impact. Goods or services produced from UMKM activities have economic value and are cheap. UMKM has advantages, one of which is having a strategic role in dealing with the ups and downs of the economy in Indonesia. Licensing is needed to guarantee the business activities of UMKM actors. Licensing is very important for UMKM players considering the increasingly global business competition and currently entering the process of economic liberalization. It is clear in Government Regulation Number 7 of 2021 concerning Ease, Protection, and Empowerment of Cooperatives and Micro, Small and Medium Enterprises, that in order to increase national economic growth, empowerment and licensing of UMKM is needed. The method used in this paper is normative juridical. The legal issue that will be examined in this paper is regarding the licensing of UMKM that provide legal protection and create a welfare state. UMKM licensing as a form of legal protection has an important value and has an impact, namely the business becomes legal, is provided with legal assistance, is used for capital applications with the aim of improving the quality and quantity of products and being able to compete with products from within and outside the country, access to business assistance from the government, and empowerment or supervision from the government so as to create a welfare state.

ABSTRAKInstagram bukan sekedar media pertukaran pesan melalui foto atau gambar. Instagram memiliki peran penting sebagai media pengungkap identitas budaya individu dalan ruang virtual. Influencer sebagai pengguna aktif Instagram dengan banyak pengikut mengalami proses ini, karena realitas diri yang nyata terpisah dalam ruang virtual yang kemudian membentuk idenitas budaya baru. Konsep komunikasi antar budaya dan media baru digunakan sebagai perspektif dalam proses menganalisa temuan data. Penelitian ini menggunakan paradigma konstruktivis dengan pendekatan kualitatif. Peneliti menggunakan metode netnografi dengan mengobservasi unggahan foto lima influencer instagram populer  Indonesia. Hasil penelitian ini terungkap realitas bahwa terdapat tiga identitas budaya virtual yang dikonstruksi oleh para influencer antara lain a) kelas sosial ekonomi, (b) agama dan (c) keluarga. Rekomendasi bagi peneliti yang tertarik tentang studi identitas budaya virtual yaitu dapat memperkaya kedalaman data dengan melakukan penelitian para influencer  di medium YouTube.   ABSTRACTInstagram not only as a medium for deliver messages through photos or pictures but also as a medium that construct cultural identity in a virtual space. Influencers as an active Instagram user with a large number of followers do this process, because of the real reality of themselves is separated in a virtual space that construct a new cultural identity. The concept of intercultural communication and new media is used as a perspective in the analysis process. This study used a constructivist paradigm with a qualitative approach. Researchers used the netnographic method by observing photo uploads of five popular Indonesian Instagram influencers. The results of this study reveal the reality that there are three virtual cultural identities of the influencers:  a) socio-economic class, (b) religion and (c) family.

Metaphorical use of Russian verbs naming properties of plants
Authors: Hu Yangyixin
Published: May 2022

The article is devoted to the linguoculturological analysis of Russian verbs naming properties of plants. The purpose of the article is to describe the metaphorical use of verbs, the primary meaning of which belongs to the thematic group "PLANTS", special attention is paid to the possible semantic mechanisms of creating a metaphor. The subject of the study is the semantic, pragmatic and culturological features of the verbs under study. In the course of the study were used materials presented in S. Aliaffar's PhD thesis "The semantic field "plant" in the Russian language", the selection of verbs was also carried out by the method of directed sampling from the "Explanatory Dictionary of the Russian Language" edited by D. N. Ushakov. As a result, 28 verbs were approved. Sharing the position of N.D. Arutyunova and M. Black that "the semantic mechanism of metaphor involves four components, only partially represented in its structure: the main and auxiliary subjects of metaphor and some properties of each of them, the article presents a variety of possible "main subjects", which are designated in the process of metaphorization, an attempt is made to describe and analyze the semantic mechanism of metaphor construction. The analysis of the metaphorical transfer associated with the plant world made it possible to facilitate the study of this issue, allowed us to replenish the lexicographic description of these units.
Clustering Categorical Data based on Finite Mixtures
Authors:   , Tran Kien
Published: May 2022

Clustering techniques are often performed to reduce the dimension of very large datasets, whose direct analysis using techniques such as regression can be computationally infeasible. The clustering of non-independent categorical variables in particular poses distinct difficulties due to its lack of a well-defined distance metric, while at the same time existing techniques tend to model variable correlations based on the latent group membership, requiring strong assumptions of conditional independence and low-to-moderate variable correlations.

This thesis proposes a joint model clustering approach for this data type based on finite mixture models, with a heavy focus on clustering based on correlation. In the case of row-clustering data with non-independent columns, we seek to model the dependency structure of columns using either pairwise joint models with misspecified likelihood, or full joint models. In the case of column clustering ordinal datasets with non-independent columns, this thesis proposes an anchor model approach where each column in the same group modelled by only one “anchor” column within the group. The result is a proper likelihood model which allows for straightforward parameter estimation while not being overly restrictive on the modelling space.
The peer social world of infants and toddlers during transition into early childcare settings
Authors:   , Ruan Peiling
Published: May 2022

AbstractOver last few decades, there has been a rapid increase in children, particularly thoseunder two years old, participating in early childcare (ECE) services in New Zealand. At thesame time, there is a dearth of research examining supporting young children under the age oftwo in their first ECE experiences. Of this body of literature, most have examined the role ofthe adults, with an emphasis on primary caregiver systems. Despite the fact that children ofthis age engage in dynamic relationships with peers, the significance of peer relationships tochildren’s transition has been largely ignored.

The present thesis aims to address this gap by inquiring into the strategies thattransitioning children use to affiliate with the peer group, and in what ways those peerscontribute to transitioning children’s sense of togetherness in the social group. A qualitativeinquiry was undertaken wherein video footage and observations were recorded of two veryyoung children transitioning into an ECE; with their interactions with peers being observedespecially. The children’s teacher was also interviewed. The findings were interpretedthrough a symbolic interactionist lens and themes were coded iteratively. Although the datawere mostly treated qualitatively, some themes are presented using descriptive statistics.

The findings showed that the two transitioning children were intrinsically interested intheir peers. They were motivated to participate in peer-related activities by using specificstrategies such as passing toys, showing humour, being close, and making physical contact.

However, at times the peer group resisted these two newcomers and their ‘initial entry’ intothe group. The transitioning children demonstrated strong resilience and perseverance. The process of peer rejection, peer acceptance, and social negotiation went in a circular formrather than in time order. In other words, there was no clear linear trajectory towards theiracceptance into the peer group. Even when others had begun to interact with the transitioningchildren, there were still instances of rejection.

In addition, this present thesis discusses some useful strategies for practitioners tofacilitate a smooth and positive transition experience for infants and toddlers with supportfrom social peers. It is my hope that practitioners can benefit from this study.
Santé et assurance maladie en Tunisie : les enjeux de la réforme de 2004
Authors: Ismaïl Safa , Zaouali Nejia
Published: May 2022

Contexte : En 2004, la Tunisie a instauré une réforme de l'assurance maladie pour remédier à plusieurs problèmes liés à l'iniquité frappante, à l'insuffisance de la couverture maladie et à la croissance exponentielle des coûts de santé et des dépenses directes des ménages. Objectifs : Le présent article visait à fournir une vision critique et une évaluation qualitative de la réforme de l'assurance maladie mise en œuvre en Tunisie depuis 2004. Méthodes : À l'aide de plusieurs sources d'information telles que la CNAM et l'INS, nous avons identifié les problèmes importants du système de l'assurance maladie, les objectifs tracés par la réforme en relation avec ces problèmes, la concrétisation des mesures prises et le niveau de réalisation desdits objectifs. Résultats : Dix-sept pour cent (17 %) de la population reste sans couverture sanitaire. En 2015, les dépenses directes des ménages tunisiens étaient de 39,8 % ce qui ne permettait pas d'éviter les dépenses catastrophiques. Presque toutes ces dépenses directes (91 %) étaient dédiées aux services de soins de santé au secteur privé. La couverture pour la lutte contre les maladies chroniques reste insuffisante. La contribution des régimes complémentaires aux dépenses de santé est estimée à 3,3 %. Les inégalités dans l'accès aux soins persistent en raison de la fragmentation de la couverture sanitaire. Conclusion : En général, les mesures prises par la réforme de l'assurance maladie ne semblent pas être efficaces pour atteindre ses objectifs. Les dépenses directes des ménages restent élevées. Pour une meilleure protection sociale de santé, les responsables de l'élaboration des politiques devraient reconcevoir la couverture sanitaire, promouvoir le secteur de santé public et garantir l'accès aux médicaments notamment pour les maladies chroniques

Value stream mapping is an important tool used in process improvement in many industries. In this study, the error records opened by the end-users to the developers who developed the screens over the software development process in the Information Technologies (IT) group of a financial institution operating in the field of participation banking were examined. This paper has been addressed in order to reduce the operational risks that may arise during the resolution of the error records encountered during the use of the software. In financial institutions, customer satisfaction is closely related to the continuity of operational processes in financial transactions. First, the authors draw the current value stream map base on the approval and solution process adventure of these error records were handled in the processing logic, analyzed and a value stream map was drawn for the current situation. Then, based on the information obtained from the current situation, approval flow of the error records is simulated with the Arena simulation program. The obtained simulation results were discussed with the stakeholders of the error resolution process. Bottleneck activities have been identified through the current situation simulation outputs. A new value stream map has been prepared, based on the seven wasteful milestones defined in the lean production philosophy. Finally, the working style of the new situation developed was adapted to the process, remodeled on the Arena software and the new model was analyzed. The simulation results showed that the error/help call records decreased by 79.8% in the in-process return volume.

Published: May 2022

In this study, 4 Salvia species found in the Salvia section distributed in the Artuklu district
of Mardin province were analyzed comparatively in terms of anatomy. Plant specimens of Salvia
section were collected from 11 localities. Anatomical studies were performed on specimens preserved
in 70% alcohol. Transverse sections taken from the roots, stems, leaves, and petioles of the species
were examined under a light microscope for anatomical examination. The anatomy of S. bracteata, S.
macrochlamys, S. suffruticosa, S. trichoclada species were examined. The S. suffruticosa species was
examined in detail for the first time anatomically. The data obtained as a result of the researches were
compared with the previous studies on the Salvia section. In anatomical examinations, it was observed
that the root, stem, leaf, and petiole structures of the taxa were similar but shapes and measurements
in addition to this the number of tissue layers and pith rows are different. Also anatomically analyses,
it has been seen that hairiness formed a difference between some species. As a result of all these
discussed data, the anatomical characters such as number of ray rows in root, number of collenchyma
layers in stem, mesophyll structures in leaves, shape of midrib and number of vascular bundles in
petiole, provide important taxonomic information.

Bu çalışmada, lityum iyon pillerin pasif termal yönetim sistemlerinden faz değişim malzemesi (FDM) kullanımı ile soğutulması deneysel olarak incelenmiştir. FDM ısı iletim katsayısının artırılması amacıyla içerisine bakır tel örgü konarak FDM/bakır tel örgü kompoziti oluşturuldu. Isıtıcı etrafına FDM/bakır tel örgü koyulduğu, yalnız FDM koyulduğu ve FDM konulmadığı durumlarda ısıtıcı yüzey sıcaklığının durağan hava ortamında değişimi incelenmiştir. Deneylerde silindirik lityum iyon pillerin 2C (1.30W) ve 3C (2.75W) deşarj durumlarında attığı ısıyı simüle etmek için 26650 pili ile aynı boyutlarda ısıtıcı kullanılmıştır. Deneylerde farklı ergime sıcaklığına sahip iki adet FDM kullanılmıştır. Sürekli rejimde yürütülen deneylerde ısıtıcı etrafına FDM(CrodaTherm37)/bakır tel konulması durumunda FDM katı halde iken FDM+cam ısıl direncini %52 düşürmüştür. FDM sıvı fazda olduğu durumda ise FDM/tel+cam ısıl direncini %30 artırmıştır. Tel kullanımı ısıl performansı katı ve iki fazlı bölgede olumlu etkilerken sıvı fazda olumsuz etkilediği gözlemlenmiştir. FDM/bakır tel kullanılması sayesinde FDM kütlesi ve maliyeti, %15 düşürülmüştür. FDM kullanılmadığında (durağan hava ortamı) 2C/1.30W ve 3C/2.75W deşarj/ısı üretimi durumunda ısıtıcı yüzey sıcaklığı 40˚C’ ye sırasıyla 755 s ve 400 s’de gelmiştir. 2C deşarj oranı için bu süre CrodaTherm37/Tel örgü kullanılarak FDM kullanılmayan duruma göre %703 artırılabilmiştir. FDM’lerin ergime sıcaklıkları göz önüne alındığında, kısa süreli deşarj 2C/1.30W ısı üretimi durumunda CrodaTherm29, uzun süreli çevrim şeklinde şarj/deşarj 2C/1.30W ısı üretimi durumunda ise CrodaTherm37 FDM kullanımı tercih edilebilir.
The Early History of Undergraduate Construction Education in the United States
Authors: Burt Richard
Published: May 2022

The history of undergraduate construction education in the United States has garnered faint attention by academics and little is known about construction programs in existence before the formation of the Associated Schools of Construction (ASC) in 1965. This study uses contemporary historical documents to identify construction programs that existed before the second world war, and programs created during or shortly after the war. A total of nine programs with courses related to the “building industry” are identified as being in operation prior to 1941 and 23 programs are identified as existing by 1946, and 36 programs by 1953. The research also identifies, and analyzes a study conducted by Arthur A. Hood of the Johns-Manville Company who has a major influence on establishing programs during and after the war. Over half of the institutions represented at the inception meeting of the ASC were identified as being established as a result of this study and the actions of Arthur A. Hood. There is a strong case to be made for Arthur A. Hood being the founding father of construction education in the United States.
Energy and Cost Comparison of Building Cooling Systems
Authors: Adhikari Sanjeev , Gordy Parker
Published: May 2022

Cooling a building can be approached with several different methods, but determining which method to pursue can be a matter of operator preference. This study examines four equipment systems of building cooling (Variable Refrigerant Flow, Rooftop Units, Hydronic Chiller, and Split Systems) and their capacities, abilities, and inabilities. These systems are then compared against one another for efficiency and operating cost in a one-year timeframe. Yearly operating cost, energy usage, and system operating time were analyzed from each unit’s performance and then compared against one another. The efficiencies, energy usage, and cost are compared to find the most efficient and cost-effective system for various owner needs and applications. Depending on the performance of the individual systems, it may be more suited to a specific application. Variable Refrigerant Flow was the most efficient due to its method of heat rejection and higher efficiency components. The chiller was also an efficient option, with the heat rejection through water being an efficient method. Rooftop units and split systems were less efficient but lowered initial capital cost. Overall, capital cost and operating expense priority determine the best method for an individual application.

Published: May 2022

E-procurement has been a part of several industries for more than three decades now. Although the construction industry is commendable for its wonders, there are few studies about the current applications of E-procurement in construction. The main objective of this research is to survey the construction companies to collect the current practices of E-procurement in construction. A survey was developed and distributed to the construction industry in the U.S., and 409 responses were obtained. The researchers used the survey responses to document the current practices of the companies that use E-procurement. It is expected that documenting the current practices of E- procurement in construction could help enhance construction companies' use of E-procurement successfully to improve their business. Further, the companies that already use E-procurement may optimize their practices. E-procurement can positively impact the construction industry by saving time, money and resolving disputes with suppliers.

To meet expectations, the agencies are increasing the rate of procurement of professional consultant services as they are facing various challenges in project scoping process (PSP). Since the scope of services (SOS) and PSP are related to each other, this study is focused on evaluation of the available data addressing the comprehensiveness of the SOS across different states. The authors focused on the design SOS and evaluated 49 documents from 8 state departments of transportation (DOTs). The authors then developed a series of criteria for assessing the comprehensiveness of these selected DOTs. Data analysis indicated significant variations across the states in terms of the criteria. Further, weights were assigned to the identified criteria and sub-criteria using the analytic hierarchy process (AHP) and the SOS documents were ranked for their comprehensiveness. Comprehensive score indices (CCi and CCe) were calculated using the level of comprehensiveness and the level of importance derived from actual SOS document pages and AHP respectively.

Emphasis on universities to increase the value of the education they provide has been mounting for several years. Through the COVID-19 pandemic, students, parents, and educators have become more aware of the value associated with the traditional relational approach of in-person educational experiences. The COVID-19 pandemic provided an unexpected opportunity to conduct a world- wide test drive of online learning, which only highlighted concerns about the return on investment in higher education. High Impact Educational practices have been seen to elevate the student learning experience and have become an initiative for many universities. This study investigated HIP participation by built environment students at one university to better understand the frequency of student participation and the impact of their participation. The results indicated that all students in the built environment disciplines participate in at least one HIP before graduating, and many participate in numerous HIPs. However, less than 20% of students identify HIP participation as a peak learning moment in the college career.

Authors: Na Ri , Aljagoub Dyala , Webber Ryan
Published: May 2022

Construction projects are spatially and temporally dual-dynamic in nature. One of the technical challenges in teaching the construction process is how to describe the spatial lay- out of construction components. Virtual reality (VR) combined with Building Information Modeling (BIM) technology (BIM-VR) has been adopted in the construction industry for years as a communication tool between stakeholders. The technology can be used to create simulations that allow employees to get an immersive experience of a construction process that has not started, to identify potential problems before construction start, and prepare construction workers for hazards that may occur on construction sites. In this paper, the author reports the findings on evaluating the effectiveness of BIM-VR technology in en- hancing students’ spatial cognition skills of building and construction components. The evaluation was conducted using two different quantitative approaches. First, the before and after scores of students’ spatial cognition skills were measured. The statistics of score changes were used to evaluate the effectiveness of the technology. Then, an assessment was conducted in which a survey was sent to students after completion of the course to gauge their feedback on the effectiveness of the BIM-VR application which had a positive trend.

Authors: Najmi Sarooghi Emad , McCuen Tamera
Published: May 2022

This paper aims to identify the construction-related strategies in smart cities that could assist contractors in disrupting traditional construction processes using new technologies and processes. In this research, a thematic analysis was conducted to categorize the construction-related strategies in different themes by analyzing the smart cities' documents. The publicly available documents of 24 smart cities in the United States and around the globe, along with four international governments whose action plans will disrupt traditional construction processes, were analyzed. Based on the results, 29 action plans in six different themes were identified, including 1) Modern Infrastructure, 2) Livable Climate, 3) Efficient Mobility, 4) Education/Training, 5) Inclusive Economy, and 6) Affordable Housing. This paper shows that several smart cities have implemented some construction-related action plans, but other cities have no strategies related to the construction industry. The results of this paper could be helpful for further research to identify the future direction of construction in smart cities and define the knowledge and requirements needed for contractors to implement the action plans in smart cities.

Published: May 2022

Urbanization and the evolution of people's lifestyles have a significant impact on the quantity of waste that is generated and dumped each year. In addition, due to the emergence of the Covid-19 pandemic, the use of masks has increased significantly, and the amount of plastic waste generation worldwide has doubled. These wastes have had a negative impact on the environment and have attracted the attention of many departments. Faced with both increasing amounts of generated plastic wastes and the growing interest of sustainability, the construction sectors must take an advantage using recycled plastic wastes in construction applications to reduce the negative impacts of the generated plastic wastes, while meeting future infrastructure demand. This study conducts a comprehensive analysis of the opportunities and challenges of plastic waste application in the construction industry. In this context the objective of the study is to (i) explore the most used plastic wastes in construction industry, (ii) explore potential application of plastic waste in construction industry, (iii) explore potential application of COVID-19 plastic waste in construction industry, (iv) outline challenges and opportunities involving the applications, and (v) Provide recommendations for advanced research required for plastic waste application in construction industry. It is concluded that the use of plastic waste in construction will significantly improve environmental sustainability, reduce the construction cost, improve the performance of construction, and serve as a reliable supply of construction materials. Finally, to overcome challenges areas for further research are also suggested.
Effectiveness of the Synchronous Online Flipped Classroom on Students’ Learning During the COVID-19 Pandemic
Authors: Shim Euysup , Inti Sundeep
Published: May 2022

The flipped classroom approach is a pedagogical method for students' active learning and engagement in learning activities. Many Construction Management (CM) educators have adopted this pedagogical method and confirmed its benefits in classroom teaching. However, the effectiveness of the flipped classroom model on students' learning in 100% synchronous online courses, specifically for CM education, is not reported. Considering a massive shift to virtual learning during the Pandemic, CM educators need to understand the feasibility and effectiveness of flipped classrooms for online courses, which is the focus of the current study. This paper initially presents the technologies and methods adopted in this study to transform two online CM courses into a flipped approach. Later, the flipped classroom model's effectiveness is assessed through student feedback. The results indicated a mixed response from the students regarding the effectiveness of the flipped classroom model over traditional teaching. Although around two-thirds of the student body recommend the flipped classroom model over conventional education, they now prefer conventional face-to-face teaching over the online flipped classroom. This mixed response may be due to the lethargy caused by complete remote learning in 2020 due to Covid-19.
Adaptation of Autonomous Vehicles into Highways and Roads
Authors: Korkmaz Kasim , Koo Hyun
Published: May 2022

Autonomous vehicles (AVs) are considered as the one of main components of the future transportation system. By 2040, over 90% of the vehicles are expected to be autonomous vehicles in the U.S. Therefore, it is imperative that the infrastructure systems, including highways and roads, need to be updated accommodate AVs before they become prominent in the transportation system. The main benefits of AVs are easing congestion, shortening commutes, reducing fuel consumption and global warming, enhancing accessibility, the liberation of parking spaces for better uses, and improving public health and social equity. To provide the current state of adaptation of AVs into highways and roads, the objectives of this paper are to investigate the current legislation and to explore impacts from the implementation of AVs and consequence considerations. Since Michigan is the home to one permanent testing site for autonomous vehicles, Michigan was selected as a case study in this paper. By providing an overview of the current implementation of AVs in the U.S., this paper will bring a comprehensive understanding of the adaptation of AVs so far and provide insights into future directions for a better implementation.
A Comparison of Contract Requirements for Design Professional Liability Insurance in Design-build Highway Projects
Authors: Lee Jung Hyun , Ashuri Baabak
Published: May 2022

In the transportation design-build (DB) industry, the responsibility of the design is transferred to the design-build team from the owner. One of the critical issues for state departments of transportation (DOTs) is design professional liability. To cover designers’ professional negligence, design professional liability insurance (DPLI) should ensure satisfactory coverages in DB projects for state DOTs. The objective of this study is to identify the variability of the DPLI policy requirements that are found in DOT DB projects. This study conducts content analysis and comparative analysis of 15 DOT archival data that consist of design-build agreements and requests for proposals. This study determines six common elements of DPLI requirements: (1) types of DPLI, (2) indemnifying party, (3) coverage amount, (4) extended reporting period, (5) retroactive date, and (6) supplemental policies. The results show that these DPLI policy elements depend on the available customizable options and requirements. Some DOTs tend to explicitly state all six elements, while other DOTs require a few of these six elements. The findings also explain the significant characteristics and implementation of each policy element. Its findings contribute to a better understanding of DPLI requirements and provide opportunities for decision-makers to reduce issues related to insurance coverage gaps.
