Οι πράσινες δημόσιες συμβάσεις ως εργαλείο της τοπικής αυτοδιοίκησης Α΄βαθμού για τη σύναψη συμβάσεων αγαθών, υπηρεσιών και έργων με μειωμένες περιβαλλοντικές επιπτώσεις
Authors: Κάρναβος Δημήτριος
Published: May 2023

Οι Δημόσιες Αρχές στην Ευρώπη ευθύνονται κάθε χρόνο για έξοδα άνω των 2 τρισεκατομ-μυρίων ευρώ ετησίως ή άλλως για το 19% περίπου του ΑΕΠ της ΕΕ, γεγονός που σήμερα καθιστά αναγκαίο να μετασχηματιστεί η δύναμη και ο ρόλος των Δημοσίων Αρχών κατά τη σύναψη Δημοσίων Συμβάσεων. Αυτός ο μετασχηματισμός απαιτεί την ενσωμάτωση της περιβαλλοντικής διάστασης και του «πρασινίσματος» των Δημοσίων Συμβάσεων - απαιτεί την πλήρη και οριζόντια εφαρμογή από όλες τις Δημόσιες Αρχές του εργαλείου των Πράσινων Δημόσιων Συμβάσεων (ΠΔΣ).Με δεδομένο ότι οι ΠΔΣ αποτελούν μέσο άσκησης πολιτικής, αλλά και το γεγονός ότι η πο-λιτική δέσμευση σε εθνικό, κοινοτικό και διεθνές επίπεδο αυξήθηκε σημαντικά τα τελευταία χρόνια, βασικός σκοπός της διδακτορικής διατριβής υπήρξε η παρουσίαση της υφι-στάμενης κατάστασης και του βαθμού διείσδυσης και εφαρμογής του εργαλείου των ΠΔΣ σε έναν από τους μεγαλύτερους «προμηθευτές» Αγαθών, Υπηρεσιών και Έργων - τους Δή-μους της Ελλάδας. Η μεθοδολογία που χρησιμοποιήθηκε βασίστηκε σε δύο διαφορετικά στάδια. Στο πρώτο, πραγματοποιήθηκε εκτενής βιβλιογραφική ανασκόπηση παραδειγμάτων και καλών πρακτικών από άλλους Δήμους της Ευρώπης. Η πλειονότητα των Αγαθών, Υπηρεσιών και Έργων που επιλέχθηκαν να παρουσιαστούν ως προς την εφαρμογή «πράσι-νων» κριτηρίων σχετίζονταν σημαντικά με τα κύρια Αγαθά, Υπηρεσίες και Έργα που «προ-μηθεύονται» οι Δήμοι της Χώρας μας. Στο δεύτερο στάδιο, πραγματοποιήθηκε εμπειρική έρευνα σύμφωνα με την οποία δομήθηκε ερωτηματολόγιο και διανεμήθηκε σε Δήμους της Χώρας, οι οποίοι με τη σειρά τους κλήθηκαν να απαντήσουν σε μια σειρά ερωτήσεων που αφορούσαν στις ΠΔΣ. Στη δομή του ερωτηματολογίου περιλαμβάνονταν συνολικά 38 ερω-τήσεις, για τη σύνταξη των οποίων λήφθηκαν υπόψη τα σημαντικότερα στοιχεία που σχετί-ζονται με το αντικείμενο των ΠΔΣ.Από τα αποτελέσματα της συνολικής έρευνας εξήχθησαν κρίσιμα συμπεράσματα, στα βασικότερα των οποίων συμπεριλαμβάνεται η ελλιπής γνώση που υπάρχει ακόμη και σήμερα γύρω από το αντικείμενο των ΠΔΣ, η απουσία συγκεκριμένων δράσεων για την συνεχή ενημέρωση/ πληροφόρηση γύρω από τις εξελίξεις στο συγκεκριμένο τομέα και η αναγκαιότητα αποσαφήνισης των νομικών ζητημάτων γύρω από την ενσωμάτωση των «πράσινων» κριτηρίων στις Δημόσιες Συμβάσεις. Μεταξύ άλλων η πλειονότητα των Δήμων της Ελλάδας (90%) πιστεύει ότι η υιοθέτηση "πράσινων" κριτηρίων στις ∆ηµόσιες Συμβάσεις θα επιφέρει σημαντικά περιβαλλοντικά οφέλη, ενώ πολύ υψηλό ποσοστό των ερωτηθέντων Δήμων (69%) αναγνωρίζει το εργαλείο των ΠΔΣ ως εργαλείο με υψηλά οικονομικά οφέλη. Τέλος, διαφαίνεται ότι θα είναι σημαντική η δημιουργία μιας κεντρικής Δημόσιας Αρχής σχετικής αποκλειστικά με τα ζητήματα των ΠΔΣ που θα καθοδηγεί τους Δήμους της Χώρας, ενώ ως εξίσου σημαντική αναγνωρίστηκε και η άμεση κατάρτιση των στελεχών των Τμημάτων Προμηθειών των Δήμων της Χώρας στα ζητήματα των ΠΔΣ.

Isolation and Molecular Characterization of Plant Growth Promoting Rhizobacteria from Groundnut (Arachis Hypogaea L.) Rhizosphere
Authors: Vasant Gunja , Bhatt Shweta , Raghav Ragini
Published: May 2023

Plant growth promoting rhizobacteria (PGPR) have been extensively employed as biofertilizers to enhance the soil nutrition for several crop plants. Rhizobacteria with beneficial effects for plants could therefore be used to reduce the dependence on synthetic chemical fertilizers in conventional agriculture. Within this study, we have explored for isolation of potential PGPR for groundnut crop from agricultural fields of Saurashtra region, Gujarat. A total of forty-two isolates from rhizospheric soil with different colony characteristics were isolated. All the strains were tested for plant growth promoting (PGP) traits to observe their properties and potential for plant growth promoting of all forty-two isolates. Plant growth promoting traits such as indole acetic acid (IAA), hydrogen cyanide (HCN), ammonia production, phosphate solubilisation and gibberellins production were performed. Thirty-four isolates produced IAA in the range of 20.7–133 µg/mL, seventeen isolates were positive for ammonia production in the range of 21.4–55.5 µg/mL, twenty-six isolates produced HCN in the range of 5.65–114.3 µg/mL,4isolates displayed phosphate solubilisation in the range of 65.6–259.5 µg/mL, and 5 isolates were positive for gibberellins production in the range of 10.2–112.1 µg/mL. Moreover, only RGKP3 and RG12 isolates displayed positive results for all PGP traits. The potent isolate RGKP3 was further identified using 16SrRNA sequencing. The strain has close evolutionary similarities with Priestia megaterium. In future study, the potent PGPR will be studied to promote groundnut plant growth, enhanced crop production, and as a potential biofertilizer.

Authors: He Jiagang , Zhu Shichao , Yu Jie , Li Hao , Li Gaosheng
Published: May 2023

A broadband decoupled dual antenna pair suitable for sub-6G mobile terminal application is proposed and designed. The multiple input multiple output (MIMO) antenna pair is arranged on the metal frame of the mobile phone, with two antenna pairs on each metal frame. The slotted antenna element structure and defect ground decoupling structure are used to achieve wide band and high isolation. Based on the decoupled antenna pair, an eight-element MIMO antenna is designed. Similarly, the coupling between antenna pairs is effectively reduced by etching the decoupled defect structure of a zigzag shape on the system surface. The prototype of the antenna array is successfully fabricated and tested. Simulation and experimental results show that the proposed eight-element MIMO antenna can fully cover the n77/n78/n79 band of 5G New Radio and 5 GHz band of WLAN. The overall efficiency of the antenna is 50%-75%, the envelope correlation coefficient (ECC) is below 0.08, and the isolation between any two ports is better than 11 dB.

Authors: Meng Lulu , Li Yingsong , Huang Zhixiang
Published: May 2023

A simple single-feeding circular polarization (CP) antenna with controlled left/right-hand characteristics is proposed and investigated for GPS L2 band applications. To achieve the CP characteristics, four arc-shaped cutting corners with different sizes are removed from a circular patch to give 90∘ phase difference to implement CP. By adjusting the radius of the four arc-shaped cutting corners, the antenna can be controlled to get left/right-hand circular polarization (L/RHCP). The proposed CP antenna is modeled, simulated, fabricated and measured, and the results demonstrate that the antenna provides an axial ratio beamwidth over 180 MHz, and impedance bandwidth of 20 MHz for L/RHCP. Additionally, the devised CP antennas have good directional radiating patterns, making them suitable for GPS L2 band applications.

In the future multi-functional detection sensing and communication integrated systems, as well as 5G/6G systems, simultaneous transmit and receive technology, as an important key technology, is an important supporting measure to achieve the simultaneous work of different functions. Looking at the problem of strong self-interference in the simultaneous multi-function application of a phased array transceiver, this paper presents the integrated cancellation architecture and corresponding method of integrated transmission domain, RF domain and digital domain, and completes principle experiment verification of interference suppression and elimination by constructing the principle experiment system. Experimental results show that in the actual hardware system 0.5 db amplitude quantification and 6-bit phase quantization control conditions, through joint using passive and active beam transfer of the domain space optimization form, at the same time in the digital domain application of the adaptive system identification interference cancellation method for further interference cancellation, above 150 dB for interference suppression can be achieved. This research will provide a certain reference for the application of simultaneous transceiver technology in future 5G/6G phased array antenna systems.
Los problemas de la industrialización autárquico-militar y su reconversión en la España de Franco: un estudio de caso sobre la Empresa Nacional de Óptica (ENOSA)
Authors: Llull Josué
Published: May 2023

El Instituto Nacional de Industria (INI) se fundó como un instrumento para el control estatal de la economía en un contexto de autarquía propio de los primeros años del régimen de Franco. Su filosofía y sus acciones fueron similares a las otras políticas económicas de la época, tanto de Europa como de Estados Unidos. Entre las compañías dependientes de este holding, en 1950, se creó la Empresa Nacional de Óptica (ENOSA) con la participación de instituciones militares y científicas. La empresa tenía como objetivo fabricar lentes e instrumentos de precisión para el ejército utilizando tecnología nacional. Sin embargo, no consiguió reducir su dependencia de las importaciones, sobre todo de Alemania. Tras muchas dificultades, fue reestructurada en 1961 y su producción se diversificó hacia la elaboración de materiales didácticos. Abordamos la historia de ENOSA como un estudio de caso sobre el fracaso del modelo de industrialización autárquica y la reconversión que las empresas del INI tuvieron que afrontar ante las nuevas condiciones socioeconómicas del desarrollismo. Como conclusión, podemos anticipar que se trató de un experimento fallido de crear una empresa tecnológica nacional que, no obstante, llegó a alcanzar una interesante proyección en el campo de la innovación educativa.
¿Qué es el perdón?: Una mirada del concepto perdón desde algunas reflexiones filosóficas
Authors: Jiménez Aceros Erika Tatiana
Published: May 2023

El presente artículo parte de las preguntas ¿Qué es el perdón? Y ¿para qué sirve perdonar? En ese sentido, para tratar de dar respuesta a éstas preguntas se emplea el método socrático, el cual permite realizar un análisis filosófico concienzudo esclareciendo, en primera instancia, qué no es el perdón o lo que creemos que es, para luego, desvelar lo qué en realidad es el perdón. Teniendo en cuenta lo anterior, desde la literatura académica se observan diversas concepciones e interpretaciones del concepto perdón. Para unos, el perdón se le asocia con la religión, un asunto divino; para otros es cuestión de la ética y la moral. Lo cierto, es que a través de la historia se han generado una serie de confusiones a cerca de lo que en realidad significa dicho concepto. Un ejemplo de ello, es admitir que el perdón es olvido o liberar de una pena o castigo, lo cual resulta todo lo contrario. En el perdón hay memoria, es un acto y emoción gratuita, y nunca renuncia a la justicia. Con todo ello, para el contenido del artículo se tomaron en cuenta algunas apreciaciones filosóficas de investigadores, como Jacques Derrida, Mariano Crespo, Amelia Valcárcel entre otros, que han tratado este tema, como una preocupación social, y que en cierta medida, nos acercan hacia una idea de concepto de perdón que pueda ser usada para ayudar a transformar los conflictos negativos en positivos, volver a estrechar lazos rotos por la violencia y generar un cambio en las acciones y actitudes de las personas que conlleve a la paz. En consecuencia, el perdón es un asunto privado que tiene consecuencias positivas en lo público.
Políticas globales y garantía del derecho de consulta previa en Colombia
Authors: Cáceres Dominguez Claudia Teresa
Published: May 2023

Este artículo hace una reflexión antropológica de dos ámbitos en los cuales se desarrolla el derecho a la consulta previa en Colombia: el internacional y el nacional. En materia normativa y estructura institucional, estos espacios se perciben como mundos aislados, cada cual con sus propios quehaceres en torno a las normas y a la práctica política. Esta propuesta plantea un escenario de geopolítica de la consulta previa que implica observar los ámbitos de políticas nacionales e internacionales, con el fin de describirlos y dar a conocer mecanismos de sujeción de los pueblos indígenas, negros y Rom a las estructuras económicas globales para proponer posibles rutas en el avance a la garantía de los derechos a la participación política.
Single-step multiplex reverse transcription-polymerase chain reaction for the detection and differentiation of QX-like infectious bronchitis virus from the Thai variant and vaccine strains H120, Ma5, and 4/91
Authors: Junnu Sucheeva , Pohuang Tawatchai
Published: May 2023

Background and Aim: QX-like infectious bronchitis virus (IBV) is a highly infectious avian coronavirus that causes respiratory and kidney disease. It is linked to increased mortality and loss of performance in infected chickens worldwide, including Thailand. Thus, a simple and rapid diagnostic method for the diagnosis of QX-like IBV is needed. This study aimed to develop a single-step multiplex reverse transcription-polymerase chain reaction (mRT–PCR) assay to detect and differentiate QX-like IBV from Thai IBV and vaccine strains used in the poultry industry (H120, Ma5, and 4/91). Materials and Methods: Primer sets specific for QX-like and Thai IBV were designed to target the S1 gene. The specificity of the technique was verified using nine isolates of QX-like IBV, four isolates of Thai IBV, and other avian viral respiratory pathogens. The detection limit was evaluated using a serial ten-fold dilution of QX-like and Thai IBV. Results: The results showed that single-step mRT–PCR could detect QX-like IBV and differentiate it from Thai IBV and the vaccine strains H120, Ma5, and 4/91. The limit of detection of the developed assay was 102.2 embryo infectious dose (EID)50/mL for QX-like IBV and 101.8 EID50/mL for Thai IBV. Interestingly, the developed assay could identify mixed infection by both IBVs in a single sample. Conclusion: The single-step mRT–PCR assay developed in this study can potentially discriminate QX-like IBV from Thai IBV and the vaccine strains H120, Ma5, and 4/91 in a single reaction. It is also suitable for use in all laboratories with access to conventional PCR equipment. Keywords: detection, QX-like infectious bronchitis virus, single-step multiplex reverse transcription-polymerase chain reaction, specificity.
Green Mediated Preparation of Transition Metal Doped
Cobalt Oxide Nanoparticles for Wastewater Treatment
Authors: Ajitha A. , Seethalakshmi K. , Meena M. , Prabhu V. Manikanda
Published: May 2023

Recent studies have shown that the metal oxide nanoparticles can inhibit bacterial growth on their
surfaces due to the creation of super oxide anion when metal ions interact with UV light. One such
metal oxide with antibacterial activity against a variety of bacteria is cobalt oxide (Co3O4). The optical
and anti-pathogen properties of cobalt oxide nanoparticles generated from egg albumin using a
microwave-assisted hydrothermal process were studied and optimized by adding copper as a dopant
at varying molar concentrations (1, 3 and 5 mol%). Bare and doped samples were analyzed using
SEM, energy dispersive X-ray spectroscopy and X-ray diffraction. The resulting structure and small
average crystalline size highlight the role of egg albumin in stabilizing and regulating size. A sample
with 5 mol% copper doped material exhibited the highest resistance zone to Escherichia coli germs.
Hence, by controlling the Cu content, both the photocatalytic and antibacterial properties can be
enchanced.

Published: May 2023

Smoking cigarettes causes lung cancer, heart disease, chronic obstructive pulmonary disease (COPD)
and other serious diseases. The damage caused by cigarette smoking is multifaceted and complex.
Exposure to harmful and potentially harmful constituents (HPHCs), created during the process of
burning tobacco, is the main reason for the development of smoking-related diseases. An alternative
way to reduce the generation of toxicants from tobacco product is to heat rather than burn tobacco.
Modified risk tobacco product (MRTP) are designed to significantly reduce or eliminate the release of
harmful and potentially harmful chemicals while preserving, as much as possible, taste, sensory
experience, nicotine delivery profile, and the ritual component of smoking cigarettes. In this review,
the chemical composition of the smoke generated by conventional cigarettes to the composition of the
aerosol generated by devices for controlled tobacco heating is compared. Also, critically assess the
current knowledge in the field, aiming towards an objective assessment of the alternative tobacco
products.

Esterification of organic molecules offers a critical process for chemical modifications. Among the various
methodologies, Steglich conditions gave easiest and mild pathways. O-Acylation of
5-chloro-8-hydroxyquinoline with different acylating counterparts has been investigated. Among the
various catalysts used, N,N-dimethylpyridin-4-amine (DMAP) in the presence of N,N′-dicyclohexyl
carbodiimide (DCC) displayed a plausible synthetic approach through the application of Steglich
esterification reaction for the synthesis of 5-chloroquinolin-8-yl-benzoates (3a-h) with good yields.
The structures of the synthesized compounds were characterized through NMR, IR and MS spectral
data. In present study, 5-chloro-8-hydroxy quinoline and its derivatives (3a-h) bearing various
substituents were investigated for their antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl (DPPH)
method. The findings revealed that the derivatives act as imminent candidates to be further developed
as antioxidant agents.

The current study aimed to develop a robust, regulatory-flexible, stability-indicating ultra high
performance liquid chromatography (UHPLC) analytical procedure compatible with mass spectrometry
for the determination of impurities in amodiaquine hydrochloride using analytical lifecycle management
(ALM) and analytical quality by design (AQbD) principles. The analytical target profile (ATP) and
critical method attributes (CMAs) for the analytical method were identified. The pH of the mobile
phase, flow rate and column oven temperature were identified as critical method parameters (CMPs)
through risk assessment studies and they were screened and optimized using the design of experiments
(DoE) to generate the design space (DS). Finally, all the impurities were well separated in a 15 min
run time by using an Acquity UPLC BEH-C18 column with 20 mM ammonium acetate pH 8.0 as
mobile phase A and acetonitrile as mobile phase B with a gradient program of time (min), % of B:
0/15, 1.0/15, 9/55, 12/55, 12.1/15 and 15/15. The flow rate was 0.3 mL min-1 and the column oven
temperature were 30 ºC. Evaluated the robustness of the developed analytical method. Degradation
products obtained from the forced degradation studies are well separated from process impurities and
main compound. Based on the stress studies, impurity-3 was identified as a key degradation product in
base degradation, while DP-1, impurity-3, DP-2, DP-3 and DP-4 were in the oxidative degradation.
Total 9 impurities out of 4 process related and 5 degradation impurities were well separated in the
developed method. Used the same method to LC coupled tandem mass spectrometer for separation
and structure elucidation of degradation products. The method validation was carried out in accordance
with ICH Q2 (R1) and USP <1225> guidelines.

Published: May 2023

In present work, nanocrystalline SmFeO3 perovskite oxide powder was prepared by sol-gel method.
Thick films of SmFeO3 were fabricated onto a glass substrate by screen printing technique and heated
at 500 ºC for 30 min. As-prepared pure nanocrystalline SmFeO3 thick films were dipped into 0.1 M
aqueous solution of cobalt chloride for different intervals of time. Microstructure and surface
morphology of both pure and Co surface modified SmFeO3 thick films were investigated by energy
dispersive X-ray analysis (EDAX) and field effect scanning electron microscopy (FE-SEM) techniques.
The FE-SEM micrograph reveals the porous nature of thick films. EDAX analysis showed that both
pure and Co modified thick films are oxygen deficient. Gas sensing performance of these films was
tested for different gases. The highest response and selectivity was recorded to 50 ppm NH3 gas at 200
ºC for SmFeO3 thick film dipped into cobalt chloride solution for 3 min. The effect of cobalt doping
and its dipping time on microstructure, surface morphology and gas sensing properties of pure SmFeO3
thick film was discussed.
Kamera-Ethnographie
Authors: Mohn Bina Elisabeth
Published: May 2023

Kamera-Ethnographie ist ein filmischer Ansatz zur Gestaltung der Wahrnehmungs- und Wissensprozesse beim ethnographischen Forschen. Dabei wird im Unterschied zur Logik der Aufzeichnung angenommen, dass Forschungsgegenstände zunächst noch gar nicht sichtbar sind. Kameraführung, Schnitt und Montage tragen als experimentelle Praktiken zur Beobachtbarkeit und Sichtbarkeit epistemischer Dinge bei. Bina Elisabeth Mohns repräsentationskritische Programmschrift zeigt, wie die Methode der Kamera-Ethnographie auch nonverbale Praktiken in ihren Choreographien und bildhaften Figuren in den Blick rückt. Eine situierte Methodologie und reflexive Pragmatik leiten zum positionierten Hinschauen und Sehenlernen an und binden selbst das Publikum in eine forschende Rezeption ein.

Dissens und Erinnerungskonkurrenz
Authors: Haustein Petra
Published: May 2023

Die Verfasserin setzt sich mit unterschiedlichen Deutungen historischer Ereignisse auseinander, deren Akzeptanz sie als unverzichtbar für eine konstruktive Auseinandersetzung mit der Vergangenheit begreift. Sie plädiert anhand von beispielhaft skizzierten moralisch verstörenden Fragen für eine pluralistische Debattenkultur auf der Basis von Faktenwissen. Insbesondere Erinnerungs- und Opferkonkurrenzen seien kaum zu überwinden, wohl aber nach ihren lebensgeschichtlichen Hintergründen und Erfahrungen befragbar. Erinnerungskultureller und geschichtspolitischer Dissens berge über Verstörendes hinaus Potential zur Stärkung von Pluralismus und Demokratie.

Parallelwelt des Gedenkens
Authors: Juhnke Dominik
Published: May 2023

Dominik Juhnke geht in diesem Beitrag der Geschichte des nachgebauten Glockenspiels der Potsdamer Garnisonkirche nach. Das Geläut wurde 1984 in Iserlohn mit privaten Spenden gestiftet und 1990 der Stadt Potsdam als Geschenk übergeben. Im Zentrum des Essays steht das romantisierte Geschichtsbewusstsein der Initiatoren und Geldgeber des Projekts. Ihre spezielle »Traditionspflege« wird als Amalgam einer Geschichts- und Identitätspolitik interpretiert, die ein nationalkonservatives Milieu von Preußennostalgikern, Heimatvertriebenen und Wehrmachtsveteranen bediente. Gleichzeitig zeigen die seit den 1980er Jahren geführten Debatten rund um die Glockeninschriften, dass das Musikinstrument stets nur Aufhänger war, um im Widerstreit der Vergangenheitsdeutungen den öffentlichen Raum mit Botschaften zu besetzen.

Küresel İnovasyon Endeksi (KIE), ülkelerin inovasyon performanslarını detaylı bir şekilde belirleyerek değişen ve gelişen rekabet ve teknoloji ortamında var olan değişimleri yakalamalarında gelişime açık ekonomilere yardımcı olmaktadır. KİE, uluslararası yenilikçiliği belirlemek amacıyla geçmişi, mevcut durumu değerlendirebilme ve geleceği belirlemeye yönelik önemli bir araçtır. KIE, yalnızca ülkelerin kapasitelerini ortaya çıkarmada değil, beraberinde ülkelerin inovasyon ile ilgili politika ve uygulamaları vasıtasıyla baskın ve zayıf özelliklerini belirgin bir şekilde göstermeye yönelik olarak da kullanılmaktadır. KİE ölçümleri sayesinde, ülkeler hangi faktörleri ne kadar önemseyeceğini, hangi faktörlerde yetersiz olduklarını, hangi faktörlerde iyi performans gösterdiklerini görebileceklerdir. Böylelikle eksikliklerini giderebilecek ve daha iyi olmak için neler yapılması gerektiği sorusuna cevap bulabileceklerdir. Bu çalışmada, Türk Devletleri Teşkilatına (TDT) üye ülkelerin KIE 2020 verilerine göre inovasyon performansları ÇKKV yöntemleriyle analiz edilerek ülkelerarası karşılaştırmalar yapılmıştır. Ülke karşılaştırmaları küresel endekste kullanılan 15 kritere göre yapılmış ve bu kriterlerin ağırlıkları da Entropi yöntemiyle hesaplanmıştır. Sonrasında TOPSIS yöntemi kullanılmış ve ülkeler inovasyon performansları odağında sıralanmıştır. Elde edilen sonuçlara göre ülke sıralaması; Türkiye, Azerbaycan, Kazakistan, Tacikistan, Kırgızistan ve Özbekistan şeklindedir. Entropi ile yapılan ağırlık hesabında ise en fazla ağırlığa sahip olan “yaratıcı çıktılar” kriteri olup en düşük ağırlığa sahip olan ise “pazar gelişmişliği” kriteridir.

Research and Development Agency for Road and Bridge Ministry of Public Works and Public Housing (Balitbang Pusjatan Kemen-PUPR) has developed a bridge inspection software called Visual Inspection of Bridge or INVI J. The INVI J application which based on Android software and web has been implemented starting in 2018 at all Balai Besar Pelaksanaan Jalan Nasional (BBPJN) throughout Indonesia. Related to that, the analysis of  user perspective towards the utilization of the INVI J is significant to be done.This research was conducted by creating and distributing questionnaires to several INVI J software users within the Balai Besar Pelaksanaan Jalan Nasional (BBPJN), Satuan Kerja (Satker), Pejabat Pembuat Komitmen (PPK) and Consultant.From this study, it can be concluded that in general the INVI J software is easy to learn, easy to operate and useful for users in conducting bridge surveys because it is faster than filling out a manual inspection form. However, INVI J does not have the ability and function as expected and the output produced is still not as desired, hence it is necessary to make an updating the application, in order optimize the output.

The phase of buildings maintenance in the project life cycle is still not well structured when compared to construction phase, especially in government buildings. In contrast to private buildings that have been well managed in their care. This is due to the different funding patterns and budgets and the different division of responsibilities, the private sector is easier without a long flow when they want to maintain and finance the building. The purpose of this study is to review the management of maintenance of building facilities on private projects to be recommended to government-owned buildings. Case studies were carried out on one of the private-owned buildings in Central Java by taking a review of the diesel pump facilities. The research method is by observing the process of maintaining a diesel pump that is deepened by interviews and looking at the Standard Operational Procedure (SOP). The results showed that the One Point Lesson (OPL) maintenance system through daily, weekly, monthly, and annual maintenance on private buildings was quite effective. Maintenance is categorized as autonomous, corrective, and preventive maintenance. This maintenance system has the potential to be adopted into government buildings by carrying out more in-depth analysis.

According to data from the Indonesian Central Agency of Statistic, there are 708 shopping centers (malls) in Indonesia in 2018, this figure is equivalent to 4.45% of the total trade centers in Indonesia. The basic meaning of the shopping center is a public area that connects every store with the society. Based on the theory of Ray Oldenburg, an urban sociologist from the United States, “People spend the majority of their lives in one of three places. The first is the home, the second is the workplace, and the third is any other social space”. The shopping center is one part of “the third places”, people spend their time doing economics transactions or just relaxing in the shopping center. So that with the  massively increasing development of shopping centers in Indonesia, it is need a construction design and building manage that more creative and based on eco-technology also maximize the “internet of things” as part of building operations. “Integrated Basement : Creating an Eco-Technology Basement with High-Tech Parking Area” is the main focus for the writer to design the basement as an underground building area that often used as a parking area to be a “smart parking area” and “green area” by focusing on how the building operations become efficient, environmentally friendly and high-tech integrated. Smart parking area also means that the basement be an area that can interact and be able to adapt to shopping center’s visitors. With this planning, hoped that urban society can enjoying the shopping centers as public area that environmental friendly, comfortable, also efficient and integrated.
