Authors: Arzhanova K. A. , Dovzhik G. V. , Dovzhik V. N.
Published: November 2022

The article examines the influencer-marketing impact in the digital environment as one of the most popular lines of digital communications. The problem is the difficulty in recruiting a relevant blogger for promotional purposes. Methodologically, the study based on two basic psychological concepts: cognitive and interactive. The authors have conducted a critical analysis of scholarly literature and secondary documents and have addressed the concepts of blogger referentiality, identity and consumer identity statuses. The authors proposes and empirically verifies the hypothesis that the decision to buy an advertised product and the identity status of the consumer are interrelated. The empirical study was conducted using the author’s methodological toolkit, including an online survey using the Schneider Personality Survey. Based on the results of the study, recommendations are given for marketers to select bloggers for the target group of 18–24 year olds with different identity statuses in order to build a positive product brand. Suggestions for bloggers to interact with consumer groups with specified identity statuses are provided. Forecasts are given on the development of the influencer-marketing market, the demand for the blogging profession, the effectiveness of including the blogger’s inclusion in the company communications as potential partners, and the relationship between consumer engagement levels and social network.

Authors: Sedelnikov V. M.
Published: November 2022

The article presents the results of a study of the transformation processes of catering enterprises’ marketing strategies. In particular, the study considers the views of domestic and foreign scholars concerning the definitions of the concepts of “loyalty”, “satisfaction” and “engagement”. It has been argued that they are complementary and mutually reinforcing. The main approaches to the marketing strategies transformation (product-oriented, customer-oriented and value-oriented) have been identified, the change of targets in the formation and implementation process of the marketing strategies (from focusing on the company’s product to focusing on interaction with consumers) has been reflected, and that constitutes in whole the scientific novelty of the study. From the standpoint of a value-oriented approach, the marketing strategy concept has been clarified as a system of strategic actions for the development of a company, which aims to form long-term relationships with consumers and increase their level of involvement, satisfaction and loyalty throughout the entire period of interaction with the consumer (customer life-time cycle). As a direction for further research, is indicated an assessment of the satisfaction, involvement and loyalty influence level on the implementation effectiveness of catering enterprises’ marketing strategies.

Published: November 2022

Mutations in spike (S) protein epitopes allow SARS-CoV-2 variants to evade antibody responses induced by infection and/or vaccination. In contrast, glycosylation sites in the S protein are conserved across SARS-CoV-2 variants, making glycans a potential robust target for developing antivirals. However, this target has not been adequately exploited for SARS-CoV-2, mostly due to intrinsically weak monovalent protein-glycan inter-actions. We hypothesize that polyvalent nano-lectins with flexibly linked carbohydrate-recognition-domains (CRDs) can adjust their relative positions and bind multivalently to S protein glycans, potentially exerting potent antiviral activity. Herein, we displayed the CRDs of DC-SIGN, a dendritic cell lectin known to bind to diverse viruses, polyvalently onto 13 nm gold nanoparticles (named as G13-CRD). G13-CRD bound strongly and specifically to target glycan-coated quantum dots with sub-nM Kd. Moreover, G13-CRD neutralized particles pseudo-typed with the S proteins of Wuhan Hu-1, B1, Delta variant and Omicron subvariant BA.1 with low nM EC50. In contrast, natural tetrameric DC-SIGN and its G13 conjugate were ineffective. Further, G13-CRD potently and completely inhibited authentic SARS-CoV-2 Wuhan Hu-1 and BA.1, with <10 pM and <10 nM EC50, respectively. These results identify G13-CRD as a polyvalent nano-lectin with broad activity against SARS-CoV-2 variants that merits further exploration as a novel approach to antiviral therapy.

Authors: Zhang Xin , Tong Shuo , Zhu Jieping , Wang Mei-Xiang
Published: November 2022

Under the catalysis of PdBr2 and a chiral phosphoramidite ligand derived from R-3,3'-bis(trifluoromethyl)-[1,1'-binaphthalene]-2,2'-diol, the upper-rim mono (2-bromoaroyl)-substituted calix[4]arene derivatives underwent facile enantioselective desymmetrization reaction to afford 9H-fluorene-embedded inherently chiral cyclophanes in good yields with ee up to 94%. The transannular arene-arene cross coupling reaction proceeded most probably through an oxidation addition of Caryl-Br bond to ligated palladium catalyst, an unusual long range 1,5-palladium migration fol-lowed by the intramolecular arylation sequence. Because of the macrocyclic strain, the newly formed 9H-fuorene segment adopts curved structure, rendering highly rigid inherently chiral macrocycles unique chiroptical property.
WaterKit: thermodynamic profiling of protein hydration sites
Authors: Eberhardt Jerome , Forli Stefano
Published: November 2022

Water desolvation is one of the key components of the free energy of binding of small molecules to their receptors. Thus, understanding the energetic balance of solvation and desolvation resulting from individual water molecules can be crucial when estimating ligand binding, especially when evaluating different molecules and poses as done in High-Throughput Virtual Screening (HTVS). Over the last decades, several methods were developed to tackle this problem, ranging from fast approximate methods (usually empirical functions using either discrete atom-atom pairwise interactions or continuum solvent models), to more computationally expensive and accurate ones mostly based on Molecular Dynamics (MD) simulations, such as Grid Inhomogeneous Solvation Theory (GIST) or Double Decoupling. On one hand, MD-based methods are prohibitive to use in HTVS to estimate the role of waters on the fly for each ligand. On the other hand, fast and approximate methods show unsatisfactory level of accuracy, with low agreement with results obtained with the more expensive methods. Here we introduce WaterKit, a new grid-based sampling method with explicit water molecules to calculate thermodynamic properties using the GIST method. Our results show that the discrete placement of water molecules is successful in reproducing the position of crystallographic waters with very high accuracy, as well as providing thermodynamic estimates with accuracy comparable to more expensive MD simulations. Unlike these methods, WaterKit can be used to analyze specific regions on the protein surface, (such as the binding site of a receptor), without having to hydrate and simulate the whole receptor structure. The results show the feasibility of a general and fast method to compute thermodynamic properties of water molecules, making it well suited to be integrated in high-throughput pipelines such as molecular docking.

Published: November 2022

A dimeric ZnII carbene complex featuring bridging and chelating benzene-1,2-dithiolate ligands is highly stable towards air and water. The donor-Zn-acceptor structure leads to visible light emission in the solid state, solution and polymer matrices with max between 577-657 nm and, for zinc(II) complexes, unusually high radiative rate constants for triplet exciton decay of up to kr = 1.5105 s-1 at room temperature. Variable temperature and DFT/MRCI studies show that a small energy gap between the 1/3LL/LMCT states of only 79 meV is responsible for efficient TADF. Time-resolved luminescence and transient absorption studies confirm the occurrence of long-lived, dominantly ligand-to-ligand charge transfer excited states in solution, allowing for application in Dexter energy transfer photocatalysis.

Published: November 2022

Amines and carboxylic acids are abundant building blocks for synthesis that classically are united to form an amide bond. To access new pockets of chemical space we are interested in the development of complementary amine–acid coupling reactions. In particular, the formation of carbon–carbon bonds by formal deamination and decarboxylation would be an impactful addition to the synthesis toolbox. Here we report a formal cross coupling of alkyl amines and aryl carboxylic acids to form C(sp3)–C(sp2) bonds following pre-activation of the amine–acid building blocks as a pyridinium salt and N-acyl-glutarimide respectively. Under nickel-catalyzed reductive cross-coupling conditions, a diversity of simple and complex substrates are united in good to excellent yield. High-throughput experimentation was essential to the development of the reaction, and to the discovery of performance-enhancing additives such as cyclic imides, RuCl3 and GaCl3. Preliminary mechanistic investigations suggest that RuCl3 supports the decarbonylation event, increasing reaction selectivity. Numerous amine or acid containing pharmaceuticals are successfully diversified under the optimized conditions.

We present a benchmark study considering AEPA16 dataset comprising atomization energy for boron group clusters. This dataset covers 46 different methods from the different range of density functionals and post HF, where MRACPF is considered as the reference. The performance of basis set is analyzed by comparing the atomization energy with the CCSD(T)\CBS results. None of the GGA and meta-GGA are accurate and the popular PBE shows maximum error among the all methods, whereas B3LYP has moderate performance. M06 and RSHX DFAs have good performance among all the DFAs. NEVPT2 is the most accurate among all the methods considered followed by coupled cluster methods, i.e., CCSD(T) and DLPNO-CCSD(T), indicating the importance of perturbative correction. All the basis with M06 show promising results (absolute error \textless 1 \kmol) with respect to the CCSD(T)\CBS. From the cost -- accuracy investigation, def2-SVP is recommended in our study as it is the fastest. Hence, we have recommended M06/def2-SVP for boron group clusters. Furthermore, we have explored the structural progress of global and local minima of pure, binary, and ternary of boron group clusters up to size 12. One characteristic feature is that Ga clusters have more rectangular faces, whereas B and Al clusters have mostly trigonal units in pure cluster's form. We have got core-shell like structures, where, B makes core structure with both the Al and Ga atoms; however, Ga favors the outer position in the binary clusters. This behavior confirms the higher cohesive nature of B as compared to the Al and Ga atoms. The most favorable cluster is obtained with the maximum cluster size (12) with the equal composition of Al and Ga atoms for binary clusters. From the BE and ME of ternary clusters, we have obtained 16.67-40% B, 16.67-60% Al, and 20-50% Ga composition are favorable for the relatively stable ternary clusters as it shows negative ME.

Halogenation of pyrrole requires strong electrophilic reagents and often leads to undesired polyhalogenated products. Biocatalytic halogenation is a highly attractive approach given its chemoselectivity and benign reaction conditions. Whilst there are several reports of enzymatic phenol and indole halogenation in organic synthesis, corresponding reports on enzymatic pyrrole halogenation has been lacking. Here we describe the first in vitro functional and structural characterization of PrnC, a flavin-dependent halogenase that can act on free-standing pyrroles. Computational modelling and site mutagenesis studies identified three key residues in the catalytic pocket. Moderate resolution map using single-particle cryogenic electron microscopy (CryoEM) reveals PrnC to be a dimer. This native PrnC can halogenate a library of structurally diverse pyrrolic heterocycles in a site-selective manner and was applied in the chemoenzymatic synthesis of a chlorinated analog of the agrochemical fungicide, Fludioxonil.
Digitizing Chemical Discovery with a Bayesian Explorer for Interpreting Reactivity Data
Authors: Cronin Leroy , Mehr S. Hessam , Caramelli Dario
Published: November 2022

Interpretating the outcome of chemistry experiments consistently is slow and often introduces unwanted hidden bias. This difficulty limits the scale of collectable data and often leads to exclusion of negative results, which severely limits progress in the field. What is needed is a way to standardise the discovery process and accelerate the interpretation of high dimensional data aided by the expert chemist’s intuition. We demonstrate a digital Oracle that reasons about chemical reactivity using probability. By doing >500 reactions covering a large space and retaining both the positive and negative results the Oracle was able to rediscover eight historically important reactions including the Aldol condensation, Buchwald-Hartwig amination, Heck, Mannich, Sonogashira, Suzuki, Wittig and Wittig-Horner reactions. This new paradigm for decoding reactivity validates and formalizes the expert chemist’s experience and intuition, providing a quantitative criterion of discovery scalable to all available experimental data.
THE PRINCIPLE OF NON-INTERFERENCE IN A PERSONAL LIFE AS A MANIFESTATION OF FREE WILL
Authors: Savchenko Viktor Oleksandrovych
Published: November 2022

Introduction. The article is devoted to the connection of free will with the principle of inadmissibility of arbitrary interference in the sphere of a person's private life. Civil law is based on the basic principles that underlie it. A full understanding of the legal nature of these principles will allow a deeper understanding of the paradigms and vectors on which civil law develops. At the same time, at the heart of all the principles of civil law is the legal definition that determines all its ideas. Freedom of will is recognized as such a basis.

In the study, the author argues that freedom of will is the fundamental basis for the principles of civil law. The connection between the principle of inadmissibility of arbitrary interference in the sphere of personal life and freedom of will has also been proved.

Summary. First of all, the connection of free will with the principle of inadmissibility of arbitrary interference in the sphere of a person's private life is recognized as unambiguous. The principle of inadmissibility of arbitrary interference in the sphere of a person's private life is multidimensional and corresponds to a large number of civil and constitutional rights. In particular, in Art. 32 of the Constitution of Ukraine stipulates that no one may be interfered with in his personal and family life, except in cases provided by the Constitution of Ukraine. Recognition of a person's private life and prohibition of arbitrary interference in it runs like a red thread through all legislation. The combination of the principle of inadmissibility of arbitrary interference in the sphere of personal life and freedom of will should be justified by the thesis that the law governs the external relations of freedom of one person to the freedom of others, and morality - the internal motivations of the person.

Conclusions. freedom of will is necessarily manifested in the application of the principle of inadmissibility of arbitrary interference in the sphere of personal life. On the one hand, this principle proclaims the protection of free will applied in the private life of man. On the contrary, this principle restricts the freedom of will of other parties to the legal relationship by prohibiting arbitrary interference.

Authors: Pokalchuk Mykhailo Yuriiovych , Yakubov Bogdan Viktorovich
Published: November 2022

The article highlights the urgent problems of legal regulation of food security in Ukraine in the context of the Covid-19 coronavirus pandemic. In the course of the study, the authors analyze the regulations governing food security for efficiency and relevance to today's realities, immediacy in relation to the negative consequences caused by the Covid-19 coronavirus pandemic. The very concept of food security, approaches to its definition, research of elements of which it consists, their theoretical and practical value are considered also. There are ways and methods by which you can determine the level of food security in a country. Particular attention is paid to product availability as a fundamental element of food security. The authors reveal it in both formal and factual aspects, emphasize the inseparable relationship of these aspects, confirm this with illustrative examples.

The article also considers the impact of the negative effects of the Covid-19 coronavirus pandemic on the functioning of agricultural law institutions, so the authors propose amendments to various regulations of current agricultural legislation with the sole purpose - to save and restore food security in Ukraine.

The authors emphasize the urgency of the problem of the lack of a special law on food security in Ukraine, while citing the views of agricultural industry and legislation on this issue in terms of the feasibility of the fastest and most effective filling of such gaps. Therefore, the article proposes and substantiates the adoption of a single, unified, special law that will regulate legal relations arising in relation to food security of Ukraine. In its development, the authors advise to borrow positive experience in the field of food security of advanced countries. In addition, in order to respond quickly to the challenges of Covid-19, it is necessary to adopt the relevant bylaws on the basis of a special law by the executive authorities in the field of economy and agriculture.

Much attention is paid to international cooperation in the field of export and import of agricultural products, because this circulation of agricultural products between countries directly affects the food security of each of them. The authors conclude that it is taking into account the obligations in the framework of international cooperation, Ukraine should develop a specialized regulatory framework in the field of food security.

Published: November 2022

Corruption as an international global phenomenon is inherent to all countries regardless of their political system and level of economic development. Ukraine as a State-participant of Convention of the UNO against corruption is obliged to implement its requirements to develop and carry out effective coordinated policy of tackling corruption, that contributes to participation of society and represents principles of law and order, proper management of state affairs and state property, honesty and incorruptibility, transparency and responsibility. It is necessary to mark that corruption always grows, when a country is on the stage of transformation. As Ukraine passes not just the stage of democratization of the political system , but carries out fundamental transformation of the economic and political system, legal and social ones, so an increase of level of corruption is objectively conditioned factor.

The article reports , that effective preventions and counteraction to corruption are impossible without coordinated work of all state bodies. Thus Anticorruption strategy covers the question of functioning of the general system of prevention of corruption, determines priorities of prevention of corruption in the certain sectors of state administration and pay a lot of attention to the question of responsibility for corruption.

There fore the question of scientific accompaniment of public anticorruption policy during its development and realization is relevant , and also it is of vast importance to form the modern infrastructure of scientifically-expert and analytical activity.

Non-compressible torso hemorrhage (NCTH) (i.e. bleeding from anatomical locations not amenable to control by direct pressure or tourniquet application) is a leading cause of potentially preventable death after injury. In select trauma patients with infra-diaphragmatic NCTH-related hemorrhagic shock or traumatic circulatory arrest, occlusion of the aorta proximal to the site of hemorrhage may sustain or restore spontaneous circulation. While the traditional method of achieving proximal aortic occlusion included Emergency Department thoracotomy (EDT) with descending thoracic aortic cross-clamping, resuscitative endovascular balloon occlusion of the aorta (REBOA) affords a less invasive option when thoracotomy is not required for other indications. In this article, we review the innovation, pathophysiologic effects, indications for, and technique of EDT and partial, intermittent, and complete REBOA in injured patients, including recommended methods for reversing aortic occlusion. We also discuss advantages and disadvantages of each of these methods of proximal aortic occlusion and review studies comparing their effectiveness and safety for managing post-injury NCTH. We conclude by providing recommendations as to when each of these methods may be best, when indicated, to manage injured patients with NCTH.

Restrained Strong Resolving Hop Domination in Graphs
Authors: Abragan Armalene , Rara Helen
Published: November 2022

A set S ⊆ V (G) is a restrained strong resolving hop dominating set in G if for every v ∈ V (G)\S, there exists w ∈ S such that dG(v, w) = 2 and S = V (G) or V (G)\S has no isolated vertex. The smallest cardinality of such a set, denoted by γrsRh(G), is called the restrained strong resolving hop domination number of G. In this paper, we obtained the corresponding parameter in graphs resulting from the join, corona and lexicographic product of two graphs. Specifically, we characterize the restrained strong resolving hop dominating sets in these types of graphs and determine the bounds or exact values of their restrained strong resolving hop domination numbers.

Subnormality and Theory of L-subgroups
Authors: Jahan Iffat , Ajmal Naseem , Davvaz Bijan
Published: November 2022

The main focus in this work is to establish that L-group theory, which uses the language of functions instead of formal set theoretic language, is capable of capturing most of the refined ideas and concepts of classical group theory. We demonstrate this by extending the notion of subnormality to the L-setting and investigating its properties. We develop a mechanism to tackle the join problem of subnormal L-subgroups. The conjugate L-subgroup as is defined in our previous paper [4] has been used to formulate the concept of normal closure and normal closure series of an L-subgroup which, in turn, is used to define subnormal L-subgroups. Further, the concept of subnormal series has been introduced in L-setting and utilized to establish the subnor-mality of L-subgroups. Also, several results pertaining to the notion of subnormality have been established. Lastly, the level subset characterization of a subnormal L-subgroup is provided after developing a necessary mechanism. Finally, we establish that every subgroup of a nilpotent L-group is subnormal. In fact, it has been exhibited through this work that L-group theory presents a modernized approach to study classical group theory.
Mathematical Analysis and Simulation of an Age-Structured Model with Two-Patch and an Uncontrolled Migration: Application to Tuberculosis
Authors: Badjo Kimba Abdoul Wahid , Moustapha Dijbo , Saley Bisso
Published: November 2022

In this paper, we studied a two-patch age-structured model of tuberculosis in a context where the migration is not controlled. Motivated by the fact that no author has highlighted the impact of migration on the dynamics of transmission of tuberculosis. Each subpopulation is subdivided into five compartments: susceptible; latent, vaccinated, infective and treated. After the determination of the reproductive numbers R(ψ, ρ) and R0(ρ), we established the conditions of the global and local stability of the equilibrium point without disease. It has been shown that there is only one point of endemic equilibrium. Numerical simulations show that uncontrolled migration negatively influences the dynamics of tuberculosis.

A set S of vertices in G is a 2-resolving hop dominating set of G if S is a 2-resolving set in G and for every vertex x ∈ V (G)\S there exists y ∈ S such that dG(x, y) = 2. The minimum cardinality of a set S is called the 2-resolving hop domination number of G and is denoted by γ2Rh(G). This study aims to combine the concept of hop domination with the 2-resolving sets of graphs. The main results generated in this study include the characterization of 2-resolving hop dominating sets in the join, corona and lexicographic product of two graphs, as well as their corresponding bounds or exact values.

Authors:   The Korean Society of Cognitive Therapeutic Exercise, Oh Seung Jun , Kim Hyun Sung
Published: November 2022

This study aimed to investigate the effect of upper-limb robot therapy on cognitive function and activities of daily living after a stroke.
A total of 20 stroke patients were enrolled from C hospital in this study. Each patient was assigned to either the control or experimental group. The experimental group received both upper-limb robot therapy and general rehabilitation treatment, while the control group only received the general rehabilitation treatment. The intervention time was for 60 minutes in 5 sessions weekly for 8 weeks. To examine changes before and after treatment, outcomes were assessed using the Mini-Mental State Examination Modified-K (MMSE-K), K-Barthel Index (K-MBI), and Fugl-Meyer Assessment (FMA). After 8 weeks of intervention, a significant improvement was observed in the experimental group compared to that in the control group (MMSE-K (p=.011), K-MBI (p=.028), and FMA (p=.021)). Thus, this study showed promising results where stroke patients were able to recover cognitive function and daily life activities effectively with upper-limb robot therapy when provided in combination with general rehabilitation treatment as compared to only general rehabilitation treatment.

Published: November 2022

This study developed a saccadic eye movement training program and attempted to verify its effectiveness as a tool for training saccadic eye movements in stroke patients.
This study included 26 stroke patients. The subjects were classified into an experimental group and a control group through random allocation, and the King-Devick test was administered as the pre-test. After the pre-test, the experimental group performed an existing occupational therapy intervention and a saccadic eye movement training program intervention for a total of 16 sessions. The control group underwent existing occupational therapy and additional occupational therapy interventions. After four weeks, the experimental and control groups were re-tested.
The time and number of errors in the King-Devick test before and after intervention in both groups showed statistically significant differences (p<.05), and both parameters in the King-Devick test decreased after the intervention.

Marital satisfaction affects many aspects of people’s individual and social life. It is affected by factors such as economic strain and the couple’s interaction. Therefore, this study was conducted to determine the relationship between economic pressure, husband-wife interaction, and husband's marital satisfaction. The data for this study were gathered from an online survey of 33 informal working husbands and 32 formal working husbands from West Java. The respondents were selected by using the purposive sampling technique. The Economic Pressure Questionnaire and Interpersonal Behavior Scale measured economic pressure and husband-wife interaction. ENRICH Marital Satisfaction instrument has been used to measure a husband's marital satisfaction. The findings revealed that economic pressure and husband-wife interaction significantly relate to the husband’s marital satisfaction. Multiple regression analysis was used to analyze the relative strength of independent variables in predicting a husband’s marital satisfaction. The results indicated that husband-wife interaction was found to have the strongest influence on a husband’s marital satisfaction. Findings imply that there is a need for strategies to improve the quality of husband-wife interactions to help prevent divorce prepared by both partners and related parties.

Subjective well-being is considered one of the scientific measures to represent one's happiness and quality of life. This research aims to analyze the influences of parenting practices and characters toward subjective well-being in adolescents. This research used the explanatory method and was conducted in Bekasi, which was chosen based on a purposive approach.

The collected data included adolescent characteristics (age and gender), family characteristics (parents' age, education, work status, and family size), parenting practices, characters, and subjective well-being. The data obtained were then processed and analyzed descriptively and inferentially using Microsoft Excel and SPSS 26. The results show that the parenting practices index and subjective well-being index were in a low category, while the character index was in the moderate category. The correlation test found that female adolescents tend to receive better parenting practices. Furthermore, significant correlations were also found among parenting practices, characters, and subjective well-being. This regression test found that parenting practices from the parents and adolescents’ characters significantly influence subjective well-being in adolescents.
STRATEGI KONSERVASI TUMBUHAN HOYA DI BODOGOL, CAGAR BIOSFER TAMAN NASIONAL GUNUNG GEDE PANGRANGO MELALUI PROMOSI EKOWISATA

Taman Nasional Gunung Gede Pangrango (TNGGP) merupakan salah satu kawasan konservasi in situ di Jawa Barat dan telah ditetapkan sebagai cagar biosfer sejak tahun 1976 karena nilai keanekaragaman hayati dan jasa lingkungannya bagi masyarakat sekitar.  Prinsip konservasi yang berkembang saat ini tidak hanya melalui pengawetan jenis namun juga harus bisa mengakomodasi dan mengatur pemanfaatan secara lestari.  Keterkaitan dengan posisi TNGGP sebagai kawasan cagar biosfer, diperlukan harmonisasi antara kepentingan konservasi kawasan dan biodiversitas yang terkandung di dalamnya dengan kesejahteraan masyarakat sekitarnya.  Salah satu masalah yang di hadapi adalah semakin menyempitnya lahan pertanian garapan masyarakat sekitar kawasan karena semakin bertambahnya kegiatan alih fungsi lahan pertanian menjadi pemukiman atau penggunaan lainnya.  Kondisi ini dikhawatirkan akan meningkatkan tingkat gangguan ke dalam kawasan.  Oleh karena itu perlu dikembangkan strategi pemanfaatan sumberdaya hayati yang tidak mengganggu keberadaan populasi dan ekosistem di dalam kawasan konservasi, namun dapat membantu mengatasi permasalahan perekonomian masyarakat sekitar kawasan.  Salah satu potensi sumberdaya hayati yang terdapat di TNGGP yang dapat dikembangkan adalah tumbuhan dari marga Hoya (Apocynaceae: Asclepiadoideae).  Tumbuhan Hoya saat ini semakin populer dimanfaatkan sebagai tanaman hias, di samping memiliki manfaat lainnya, yaitu sebagai sumber bahan obat, sekaligus penyerap polutan/racun dalam ruangan maupun bahan industri kosmetik.  Secara ekologis, Hoya sebagai tumbuhan epifit turut menyumbang biomasa dan penyerapan karbon tanpa menambah penggunaan lahan, dan fungsi ekologis lainnya terkait asosiasinya dengan serangga peyerbuk maupun semut dan lainnya.  Terdapat 10 jenis Hoya di TNGGP, dan jumlah jenis terbanyak terdapat di resort Bodogol.  Jenis-jenis tersebut juga terdapat di jalur interpretasi Bodogol, sehingga kekayaan jenis jenis Hoya tersebut dapat dimanfaatkan secara lestari untuk dapat digunakan sebagai alternatif mata pencaharian penduduk sekitar antara lain melalui pengembangan ekowisata Hoya.  Pengembangan ekowisata Hoya di TNGGP dapat difokuskan di lokasi Resort Bodogol dengan berbagai bentuk, misalnya dengan pembentukan Kampung Hoya di Desa Bodogol dan jalur wisata Hoya di Resort Bodogol.   Selain itu wilayah resort Bodogol juga merupakan wilayah percontohan sebagai Pusat Pendidikan Konservasi Alam dan juga sebagai stasiun Penelitian yang tentunya pengembangan ekowisata Hoya di Bodogol akan selaras dengan fungsi tersebut.   Adapun pengembangan Kampung wisata Hoya dapat melibatkan masyarakat setempat dan beberapa stakeholder terkait.

Aim: To assess treatment efficacy in the management of orofacial myogenous conditions by a retrospective study of patients seen at an orofacial pain clinic. Methods: A single researcher conducted a retrospective review of charts of patients assigned to the same provider, to identify those with myogenous disorders. The reviewed charts belonged to patients of the Orofacial Pain and Oral Medicine Center of the University of Southern California, seeing from June 2018 to October 2019. Results: A total of 129 charts included a myogenous disorder; the most common primary myogenous disorder was localized myalgia (58 cases, 45.0%). Arthralgia was the most common TMD concomitant condition (82.9%), followed by internal derangement (41.9%). Forty-six patients were given a home-based conservative physical care protocol; ten additional cases also received trigger point injections (lidocaine or mepivacaine) with pain assessed by verbal numerical rating scale (NRS), pre- and post-treatment follow-up within 24 weeks. There was a significant overall pain improvement in NRS pain from pre- to post-treatment (p<0.001), though no difference was found between conservative treatment and trigger points in NRS pain (p=0.130). However, the rate of NRS unit improvement per week in the conservative treatment group was significantly greater than the trigger point group (p=0.036). These apparently contradictory results might be due to the small sample size of the trigger point injections group (n=10). Conclusion: In this small sample size study, the addition of trigger point injections to conservative treatment provided inconclusive results, further studies are needed.
