Вступ. Фармацевтична промисловість стабільно розвивалася до війни та мала сталу тенденцію збільшення щорічного товарообо­роту. Пандемія та карантинні обмеження позна­чилися на стані логістики й, відповідно, на динаміці галузі. Проблема. Повномасштабне вторгнення та воєнний стан в Україні спричинили карди­нальні зміни в галузі, що пов’язано зі зміна­ми ланцюгів постачання внаслідок бойових дій, окупації, масових обстрілів, знищення транспортної та складської інфраструктури. Метою наукової статті є визначення основ­них проблем фармацевтичної галузі в умовах воєнного стану та перспектив застосування інструментів логістики для відновлення і роз­витку цієї галузі у повоєнний період. Методи. Використано методи елементарно-теоретичного аналізу та синтезу, економіко-статистичні методи і метод експертної оцінки. Результати дослідження. Основні пробле­ми фармацевтичної галузі в умовах воєнного стану можна поділити на 5 основних груп: інфраструктурні, логістичні, фінансові, вироб­ничі та соціальні. Вони змусили галузь адапту­ватися, що викликало позитивні зрушення – про це свідчать статистичні дані та прогнози зростання обсягів продажів. Ключовими факто­рами впливу на рівень якості фармацевтич­ної логістики є точне планування ланцюга постачання за часом і витратами; безпека як у контролі документів, так і в умовах навко­лишнього середовища, до яких продукт під­дається. Після погодження Україною статусу кандидата на вступ у ЄС досліджувана галузь може отримати нові можливості на між­на­родному фармацевтичному ринку. Висновки. Фармацевтична галузь присто­со­вується до умов воєнного стану, з ураху­ванням інфраструктурних, логістичних, фінан­сових, виробничих та соціальних проблем. Відновлення стабільності на фармацевтичному ринку зумовлене збільшенням кількості інвес­тицій у логістику та власне виробництво, змі­ною попиту на товари вітчизняного вироб­ництва, розширенням ринку збуту і можли­вістю для України стати фармацевтичним хабом для Європи.

Вступ. Інформатизація бізнесу не тільки уможливлює підвищити рівень доходів ком­паній, а й сприяє розвитку суспільства та окремих країн в цілому завдяки підви­щенню рівня доходів і покращенню якості життя населення. Проблема. За допомогою активної циф­рової трансформації бізнесу Україна за обся­гами і темпами розвитку зможе наблизитися до розвинутих країн. Отже, виникає необ­хідність визначення основних тенденцій ста­новлення й обґрунтування напрямів подаль­шого розвитку ІТ-сфери в Україні. Метою статті є визначення трендів роз­витку, узагальнення проблем і окреслення потенціалу та напрямів розвитку ІТ-сфери в Україні. Методи. Використано методи: статис­тичного та кореляційно-регресійного аналізу; аналізу і синтезу. Результати дослідження. Визначено позитивну динаміку трендів експорту україн­ських телекомунікаційних, комп’ютерних та інформаційних послуг. Наявний високий, але все ще недостатній рівень доступності домогосподарств до інтернету. Проведено статистичний аналіз діяльності суб’єктів гос­подарювання у сфері інформаційно-комуні­каційних технологій за їхньою кількістю, чисельністю найманих і зайнятих праців­ників та обсягом реалізованої продукції. Про­аналізовано: динаміку обсягу реалізованої продукції (товарів, послуг) на один субʼєкт господарювання і на одну тисячу зайнятих працівників в ІТ-сфері; залежність основних показників діяльності суб’єктів господарю­вання в галузі інформаційно-комунікацій­них технологій (ІКТ) і загалом всіх суб’єк­тів господарювання в Україні. Встановлено основні особливості й проблеми; окреслено напрями розвитку ІТ-сфери в Україні. Висновки. Інформаційні технології спри­яють революційному розвитку економіки та суспільства завдяки стрімкому технологіч­ному прогресу. Сьогодні це галузь, в якій працює майже 400 тис. фахівців, вона зро­стає на 25–30 % щорічно. Україна як країна з низьким рівнем доходу населення нама­гається закріпитися в глобальній цифровій економіці в умовах обмежених ресурсів, нави­чок і фрагментованих глобальних та регіо­нальних правил.

Вступ. Ринок кондитерських виробів в Україні є сформованим і висококонкурент­ним. Існує значна кількість компаній, що впродовж тривалого часу виробляють, поста­чають та реалізують достатньо широкий асорти­мент продукції, який, зважаючи на потреби та запити споживачів, постійно зазнає трансформа­ційних перетворень. Проблема. Урахування думок споживачів у формуванні асортименту товарів є одним із чисельних факторів забезпечення прибутко­вості діяльності підприємств. Отже, вияв­лення поглядів споживачів щодо формування товарної категорії шоколаду, розроблення асортимент­ної матриці задля задоволення потреб цільової аудиторії є доцільним і не втрачає актуальності. Мета дослідження – виявлення споживчих переваг шоколаду через встановлення та ранжу­вання значущості потреб споживачів, визна­чення мотивації до його придбання при формуванні товарної категорії. Методи. Використано метод інтернет-опитування, аналізу, синтезу й прогнозування. Сегментування, як процес поділу цільової аудиторії на групи, проведено за ознаками: стать, вік, сімейний стан, освіта, частота спожи­вання шоколадних виробів, місце розташу­вання підприємства торгівлі тощо. Розподіл цільової аудиторії споживачів шоколаду базу­вався на географічному, демографічному, психо­графічному, соціально-економічному та пове­дінковому принципах. Результати дослідження. Аналізуючи й узагальнюючи отримані результати, визначено основні напрями щодо удосконалення асорти­менту та споживних властивостей шоколаду, зокрема виведення на ринок безлактозного молочного шоколаду, шоколаду з рослинного молока, веганського, збільшення в інгредієнт­ному складі шоколаду частки горіхів. Результати дослідження підтверджують, що опитування споживачів є досить дієвим засобом комунікації, що позитивно впливає на результативність роботи виробничих і торго­вельних підприємств. Завдяки використанню в опитуванні відкритих запитань та аналізу відповідей можна встановити значущість проб­леми, обізнаність споживачів щодо вирішу­ваних завдань. Висновки. Найважливіший принцип марке­тингу – орієнтація на споживача, що забезпе­чується низкою заходів, вагомими серед яких є сегментація ринку та формування асорти­ментної матриці. Шляхом виявлення попиту на шоколад через інтернет-опитування встановлено, як системна діяльність виробничих і торговельних підприємств сприяє удосконаленню асорти­менту, впливає на мотивацію споживачів до придбання шоколаду.

Вступ. Подовження строків зберігання кондитерських виробів зі збереженням їхньої якості – одне з основних завдань фахівців хар­чової галузі. Проблема. Вафельні торти з жировими начинками містять значну кількість жирів з обмеженою стійкістю до окиснення, що призво­дить до погіршення їхньої якості та скорочення строків зберігання. Для гальмування згаданих вище процесів використовують антиоксиданти. Мета дослідження – обґрунтування викорис­тання іван-чаю (Chamaenerion angustifolium (L.)) окремо та в поєднанні з бурштиновою кисло­тою для подовження строку зберігання жиро­вих начинок вафельних тортів. Методи. Досліджено антиоксидантні власти­вості порошку іван-чаю (0.5 та 1 %) окремо і в поєднанні з бурштиновою кислотою (0.2 %) на кондитерському жирі для вафельних та прохолоджувальних начинок нелауринового типу серії "Віолія" прискорено-кінетичним мето­дом за температури 80 ± 2 °С з вільним доступом кисню повітря. Зміну якості досліджу­ваних зразків жиру визначено за нагромаджен­ням пероксидних, карбонільних сполук і вільних жирних кислот. Результати дослідження. Під час зберігання відбувалося прискорене накопичення первинних продуктів окиснення і тільки наприкінці збе­рігання спостерігалося помітне сповільнення швидкості цього процесу, що зумовлено нестій­кістю гідроперекисів до дії високих темпе­ратур з частковим перетворенням первинних продуктів окиснення на вторинні. Оптимальною з погляду сповіль­нення процесу окиснення виявилася добавка порошку іван-чаю в кількості 1 % у поєднанні з бурштиновою кислотою в кількості 0.2 %. Висновки. Встановлено, що речовини іван-чаю у поєднанні з бурштиновою кислотою сповільнюють окиснювальні процеси в конди­терському жирі для вафельних начинок під час зберігання, що підтверджує антиоксидантні властивості цих речовин. Обґрунтовувано вико­ристання порошку іван-чаю (0.5 та 1 %) окремо та в поєднанні з бурштиновою кисло­тою (0.2 %) для подовження строку зберігання жирових начинок вафельних тортів.

In the modern world, there is a trend towards the introduction of mechatronics in an increasing number of areas of science and technology in order to solve complex problems of controlling functional movements. One of these problems is the problem of forming surfaces of complex shapes. This task is relevant in many areas of human activity such as industry, art, and human-machine interfaces. However, among the existing solutions, there are none that could provide the possibility of forming complex surfaces under the influence of a load, while providing compact weight-dimensional characteristics. The purpose of this article is to develop the concept of a mechatronic device for the tasks of constructing surfaces of complex shape with high accuracy, the possibility of positioning under a large axial load, and measuring the axial forces exerted by objects of manipulation. The article selects the initial design parameters based on the analysis of devices similar in functionality. Next, the selection of compo-nents, the development of the layout of functional components, control electronics, and design, and the implemen-tation of a 3D model of the final device are carried out. It also describes a method for managing a group of re-ceived mechatronic devices by using a single data bus with a specialized protocol.

This paper discusses the features of methods used to synthesize a discrete-event supervisor for a group control system of mobile robots. We consider the upper levels of a group control system as a discrete-event system. Su-pervisor synthesis methods for such a system and the evaluation of their computational complexity are presented. The paper highlights the limitations of the best method in terms of computational complexity and proposes a modi-fication that allows to remove these limitations without increasing the computational complexity. The application of the modified method is demonstrated on the example of synthesizing a supervisor for the group action of a fire-fighting operation by three robots.

The paper presents the results of a numerical experiment that demonstrates the effectiveness of a control algo-rithm that maintains a sufficiently high numerical value of the robot's manipulability function , which ensures «remoteness» from a singular configuration. The problem of approaching the end effector of the space manipula-tor Canadarm2, which has seven degrees of freedom (one redundant generalized coordinate), with an object mov-ing along a known trajectory, is considered. To the six parameters that determine the position and orientation of the gripper in absolute space, a «kinematic» function , depending on the relative rotation angles of the links, has been added. In this case, the kinematics equations became closed with respect to the rotation angles. The control law includes a condition for maintaining a certain numerical value that exceeds the minimum allowable value. Illustrations in the form of three-dimensional animation obtained on the basis of numerical integration of the equa-tions of controlled motion of the manipulator and the object were built using the Mathematica computer algebra system.

Published: June 2023

The paper discusses methods that ensure the coordinated operation of two autonomous underwater vehicles, one of which is equipped with a multi–link manipulator and a vision system, and the second - auxiliary – only a vision system. These methods ensure the joint operation of two autonomous underwater vehicles both in the mode of semi-automatic positional remote control of the manipulator, and in the mode of automatic execution of operations with various objects by them. At the same time, in both modes, work is considered in situations when the vision system of the main underwater vehicle does not allow observing the object of work, which is nevertheless located in the working area of the manipulator. In this case, the auxiliary inspection underwater vehicle with its own vision system is used to monitor the object. In the semi-automatic remote control mode, the manipulator automatically takes into account the current spatial orientation of the optical axis of the vision system of the inspection underwa-ter vehicle, as well as the spatial orientations of both underwater vehicles at yaw angles in the absolute coordinate system. And in automatic mode, an accurate transfer of the spatial location and orientation of the object, which are determined using the vision system of the inspection underwater vehicle, is additionally provided to the associated coordinate system of the main underwater vehicle. At the same time, it is possible to identify and eliminate errors that occur during the operation of the vision system and navigation systems of both underwater vehicles. The re-sults of experimental studies have confirmed the operability of the proposed methods, the technical implementa-tion of which does not cause fundamental difficulties.

In the first part of the article, a system for assessing operator emotions using deep machine learning based on soft computing and designing a cognitive control system was discussed. This work develops the approach of cognitive intelligent control, describing the strategy for designing intelligent cognitive control systems based on quantum and soft computing. The synergetic effect of quantum self-organization of the knowledge base, extracted from non-robust knowledge bases of an intelligent fuzzy controller, is demonstrated. The information-thermodynamic law of quantum self-organization of the optimal distribution of the basic qualities of control (stability, controllability and robustness) and the law of quantum information thermodynamics on the possibility of extracting additional useful work based on the extracted quantum information hidden in classical states are applied. Formed (without violating the second law of quantum thermodynamics) on the basis of the extracted amount of hidden quantum information, the «thermodynamic» control force allows the robot (as a control object) to perform quantitatively more useful work compared to the amount of work expended (on extracting quantum hidden information). The guaranteed achievement of the goal of controlling the robot is carried out on the basis of the designed intelligent cognitive con-trol system using the tools of the QCOptKBTM quantum knowledge base optimizer, the structure of which includes quantum fuzzy inference (QFI). The quantum algorithm for self-organization of non-robust knowledge bases of QFI structurally relies on synergistic effects from hidden quantum information to implement the implementation of the optimal distribution of control qualities. This technology makes it possible to increase the reliability of intelligent cognitive control systems in situations of control under conditions of danger, described using a cognitive neural interface and various types of interaction with robots. The examples have demonstrated the effectiveness of intro-ducing the QFI scheme as a ready-made programmable algorithmic solution for embedded intelligent control sys-tems. The possibility of using a neural interface based on a cognitive helmet with a quantum fuzzy controller to control a vehicle is shown.

The article is devoted to the topic of great current interest that is the issue of using robots in the nuclear industry, in particular, in the module for fabrication and refabrication (MFR) of dense mixed uranium-plutonium fuel of the Pilot Demonstration Energy Complex (PDEC) of “SCP” JSC. The author attributes this to the danger or impossibility of direct participation of a person in some operations associated with adverse effects of high radiation burden and toxicity on the human body. Therefore, the author emphasizes the need to use technologies for indirect control of a number of processes or their automation, partial or complete. Particular attention is paid to the fact that robots are not introduced into existing production lines, but the robotic fabrication of fuel is implemented from the very outset, i.e. at the design stage. The author predicts that one of the benefits gained from the employment of robots will be the ability to ensure product quality at a more stable level. The article clarifies that, at the MFR, robotic manipula-tors, automated guided carts (AGC), and transfer carts will be used in the principal process in operations con-cerned with the fabrication of fuel assemblies, when handling radioactive waste, and in automated transport sys-tem lines. The growing need to solve the problems of decommissioning of nuclear energy facilities (NEF) requires new approaches to their implementation, including the minimization of human work directly in conditions of in-creased radiation background. As such an approach, it is suggested to use modern robotic technologies that make it possible to efficiently resolve problems at all stages of decommissioning of nuclear energy facilities, thereby adopting a comprehensive problem-solving approach and laying the groundwork for the future. The introduction of robotic complexes within the framework of the federal project not only has practical value for the NEF decommis-sioning in terms of resource efficiency, cost optimization and speed of project work, but also enables the imple-mentation of Russia’s strategic tasks in the social and economic spheres.

The Gradual Growth of Man in the Freedom of a Child of God
Authors: Szaniszló Inocent-Mária V.
Published: June 2023

In 2023, we find ourselves on the European continent after several social shocks caused by the COVID-19 pandemic as well as several war conflicts and especially the war in Ukraine. At the same time, however, a significant wave of population migration to the so-called safe (socially secure) countries of Western Europe continues. Despite the significant problems that this migration is causing for a politically polarised Europe, at the same time there is a loud demand not only from Western European countries for labour in numbers that are staggering in their parameters (e.g., Germany openly speaks of an economic need for up to 400 000 labour per year). And this very year marks the 55th anniversary of the publication of Pope Paul VI's long-awaited encyclical. _Humanae Vitae _(HV), which rejected all methods of artificial contraception, i.e., the artificial prevention of the conception of life, in our paper we will try to look at the problems of the culture of life in our European space with the benefit of hindsight with a few ethic-philosophical thoughts. Although 1968 resonates for our post-communist countries as the year of the failed so-called Prague Spring and the subsequent forced unwelcome visit of a contingent of Warsaw Pact troops to the territory of the then Czechoslovakia, for the countries of Western Europe and the USA other important themes of the development of post-war modern society were at stake, including new forms of freedom (including sexual freedom), pacifism and the struggle against racism, among others.
Is Data Panel Beneficial for Mental Health Assessment? Application of Pyecharts Library
Authors: Guofan Yuan , Li Xiong , Huiqiu Wang
Published: June 2023

Symptom Checklist 90 (SCL-90) and University Student Personality Inventory (UPI) are commonly used mental health scales for college students. SCL-90 reflects individual psychological state, while UPI reflects subject’s psychological adjustment ability. The combination of the two scales helps to construct a comprehensive profile of mental health. However, the current psychological test results in universities are mainly presented in the form of static cross-sectional images, lacking a dynamic visual platform and user interaction interface. Based on the test data from college freshmen by means of SCL-90 and UPI, this study uses Pyecharts library in Python to build a dynamic mental health data panel, and presents static mental health data in an interactive interface in which Kelley’s attribution theory is used to judge the causes of mental health problems. Meanwhile, latent growth curve model (LGCM) can be applied in time-based data panel and convolution neuron network (CNN) may be deployed in group-based data panel with a view to scientifically managing mental health data and effectively detecting the change of mental health levels, therefore timely providing intervention basis for follow-up psychological consultation and education.
mRNA: vaccine or gene therapy? The safety regulatory issues
Authors: Banoun Helene
Published: June 2023

COVID-19 vaccines were developed and approved rapidly in response to the urgency created by the pandemic. No specific regulations existed at the time they were marketed. The regulatory agencies therefore adapted them as a matter of urgency. Now that the pandemic emergency has passed, it's time to consider the safety issues associated with this rapid approval. The mode of action of COVID-19 mRNA vaccines should classify them as gene therapy products (GTPs), but they have been excluded by regulatory agencies. Some of the tests they have undergone as vaccines have produced non-compliant results in terms of purity, quality and batch homogeneity. The wide and persistent biodistribution of mRNAs and their protein products, incompletely studied due to their classification as vaccines, raises safety issues. Post-marketing studies have shown that mRNA passes into breast milk and could have adverse effects on breast-fed babies. Long-term expression, integration into the genome, transmission to the germline, passage into sperm, embryo/fetal and perinatal toxicity, genotoxicity and tumorigenicity should be studied in the light of adverse events reported in pharmacovigilance databases. Potential horizontal transmission (ie shedding) should also have been assessed. In-depth vaccinovigilance should be carried out. We would expect these controls to be required for future mRNA vaccines developed outside the context of a pandemic.
The smallest gap between primes
Authors: Vega Frank
Published: June 2023

A prime gap is the difference between two successive prime numbers. A twin prime is a prime that has a prime gap of two. The twin prime conjecture states that there are infinitely many twin primes. In May 2013, the popular Yitang Zhang's paper was accepted by the journal Annals of Mathematics where it was announced that for some integer N that is less than 70 million, there are infinitely many pairs of primes that differ by N. A few months later, James Maynard gave a different proof of Yitang Zhang's theorem and showed that there are infinitely many prime gaps with size of at most 600. A collaborative effort in the Polymath Project, led by Terence Tao, reduced to the lower bound 246 just using Zhang and Maynard results. In this note, using arithmetic operations, we prove that the twin prime conjecture is true.
Geological structure and occurrence conditions of the Bazhenov formation within THE South Tambey gas condensate field
Authors: Rasskazov A. A. , Potemkin G. N.
Published: June 2023

Background. In the 21st century, exploration works in the previously discovered Jurassic deposits has been launched in the north of the Yamal Peninsula. The South Tambey field was no exception, where 3D seismic surveys and exploration drilling have been carried out over the past 10 years to study of Jurassic sediments and rocks of the Bazhenov formation. Due to the lack of a data sufficient sample in the northern regions of the Western Siberia, formation was poorly studied. The main ideas were formed on wells scattered at great distances from each other without the possibility of a clear correlation. After receiving new drilling materials, it became possible to examine the deposits of the Bazhenov formation in more detail.

Aim. Determination of the structural features and occurrence conditions of the Bazhenov formation.

Materials and methods. The research was based on the logging data of exploration and production drilling. A detailed correlation of well sections was performed, which was compared and analyzed with the core description and interpretation of seismic survey materials.

Results. The lithological characteristics of rocks obtained by core description are presented, the atypical neighborhood of stromatolites and radiolarians in the section is noted. Based on a detailed correlation, the Bazhenov formation was divided into three intervals with characteristic geophysical logging values and distribution features over the area. The clinoform occurrence with development in the north-west direction is determined. Based on the areal variability, it is proposed to distinguish two types of the Bazhenov formation, and approaches to their tracing are considered.

Conclusion. The study of the Bazhenov formation revealed a co-directionality of the spatial orientation of the faults, the progradation of the Achimov clinoforms, and changes in the thickness of the Bazhenov formation. A hypothesis has been put forward about a single tectonic regime that prevailed in the Upper Jurassic and Lower Cretaceous. It is proposed to consider flower (keyboard) tectonics as the main factor that determined the structure and occurrence conditions of the Bazhenov formation.
Petrophysical characteristics of carbonate rocks of organogenic structures of late devonian age (Voronezh horizon) in Orenburg region
Authors: Ryazanov A. R.
Published: June 2023

Background. The carbonate rocks represented by organogenic structures of the Voronezh horizon (D3vr) at the Volostnovsky, Vostochno-Volostnovsky and Yuzhno-Volostnovsky fields in the northern part of the East-Orenburg oil and gas bearing region of the Volga-Ural oil and gas bearing province are studied.

Aim. To establish a connection between the structures of lithological types of carbonate rocks and their reservoir properties within the organogenic structures of the Voronezh horizon at the Volostnovsky, Vostochno-Volostnovsky and Yuzhno-Volostnovsky deposits.

Materials and methods. Stock materials on the geological structure of the northern part of the Vostochno-Orenburg district were used. Histograms of the distribution of porosity and permeability values were constructed. A petrophysical model was proposed followed by its verification and analysis.

Results. Data on the filtration-capacitance properties of carbonate rocks were analyzed. Histograms reflecting changes in porosity and permeability for individual zones of organogenic structures were constructed. A petrophysical model describing the relationship between the lithological characteristics of rocks of the selected zones and their reservoir properties was proposed. The model was verified based on the data on the Volostnovsky site and neighboring deposits.

Conclusion. The carbonate reservoirs of the Voronezh horizon are characterized by a complex structure with degraded reservoir properties. This information should be taken into account when developing deposits to ensure an increase in geological oil reserves and an extended service life of wells.

Authors: Salmanov S. S. , Nazarova Z. M. , Leonidova Yu. A.
Published: June 2023

Background. The development and implementation of the life cycle concepts of extracted raw materials seems promising for the sustainable development of mineral resources by a mining company. The practical implementation of such concepts requires a system of theoretical, methodological, analytical, and organizational procedures developed in close collaboration by state officials, researchers, and subsoil users with a particular focus on the responsibility of producers.

Aim. To carry out an analysis of the existing theoretical concepts for managing the mineral resource base of mining companies and to assess their implementation prospects. The following objectives were formulated: 1) to analyze the current situation in the field of reproduction of mineral resources; 2) to review the management approaches currently used to reproduce mineral resources; 3) to evaluate the prospects of modern concepts for the management of mineral resources in the mining industry.

Materials and methods of research. The authors analyzed the publications of foreign and domestic authors in the field of sustainable development. The complex of studies included an analysis of the theoretical concepts of management of reproduction of the mineral resource base developed to date, grouping of key indicators for assessing the sustainability of a mining enterprise, comparing approaches to management of reproduction of the mineral resource base and others.

Results. Specific features of the mechanistic approach to the management of mineral resources, as well as its limitations and drawbacks, were analyzed. Particular attention was paid to a concept of the life cycle of a mining plant. The possibilities and prospects of using a methodology of mineral resource capacity management are described.

Conclusions. The transition to modern concepts in the management of mining enterprises can be achieved under the condition of changing the existing orientation to super-profitable gross mining to that balancing social, environmental, and economic considerations.
A Spiritual Model For Recovery Of Pastors Suffering Burnout (The Pine Springs Retreat)
Authors:   ,   Andrews University, Liu Charles
Published: June 2023

Problem Seventh-day Adventist (SDA) pastors fill increasingly complex job expectations in the 1990s. Many pastors perceive they suffer from greater stressors than have any other generation of SDA pastors. Many claim burnout is hurting their job performance. It is the purpose of this study to measure the perceived levels of burnout among a cross section of SDA pastors in Southeastern California Conference of SDA (SECCSDA), plan and initiate an intervention to treat the symptoms of burnout, and analyze the effectiveness of the intervention. Method An original perception-test instrument was used to measure the perceived feelings of burnout among approximately eighty SDA pastors in southern California at a "workers' meeting" of all SDA pastors in the SECCSDA. Demographic data was also gathered by means of the test instrument in order to compare various factors and their apparent effect on perceptions of burnout. Six pastors from three selected sectors of the pastoral working force were then invited to a three-day intervention: a "Spiritual Disciplines Retreat" conducted by the author of this project report. Follow-up testing of both retreat participants and non-retreat pastors from the same three selected sectors was performed and the results compared to test the theory that an intervention of this nature would reduce perceived levels of burnout among SDA pastors. Results Though based upon a sample too small to make generalized predictions, a trend of decrease in perceived levels of burnout was recorded among those participating in the retreat as compared with those pastors not participating. Conclusions It would appear that though the practice of spiritual disciplines does affect the perceived level of burnout in SDA pastors, other factors also contribute to their overall well-being. It also seems evident that the variables which contribute to the burnout perceptions of SDA pastors are so wide-ranging that to single out non-practice of the spiritual disciplines as a major predictor of burnout would be unwise.
A Training Program in Pastoral Responsibilities for Church Elders in Lusaka, Zambia
Authors:   ,   Andrews University, Mwansa Pardon
Published: June 2023

Problem. Elders in Lusaka mission districts, Zambia, perform pastoral duties because there are only four paid pastors in charge of over 35 organized churches and 20 companies. This presents a problem because the elders have no training in these tasks. Method. In this study a theological basis for lay participation in ministry was developed. A biblical study of the duties of church elders was pursued to ascertain the qualifications and duties of elders. A Seventh-day Adventist perspective on the duties and qualifications of elders was studied. A survey was conducted in Lusaka to find out from the pastors and the elders of local churches what their duties are and the areas in which they most need training. A workshop in three areas was developed in detail. Results. The results of the theological study for lay participation showed that lay people are qualified to participate in ministry because of the indwelling Holy Spirit who gives them spiritual gifts for ministry. The New Testament suggests that elders should be blameless and have believing families. Two major duties of elders identified in the Bible are shepherding the flock of God and teaching and preaching. The results of the survey conducted identified preaching and implementing annual church activities the most important tasks. How to prepare and preach Sabbath sermons were designated as the areas in greatest need of further training. Detailed lessons for a workshop were developed in these two. In addition to these two, a detailed lesson on spiritual formation for elders was developed. Conclusion. If elders take care of churches in the absence of pastors, they need all the training possible for them to perform their tasks satisfactorily.
A Seminar on Adventists, Adornment, and Jewelry
Authors:   ,   Andrews University, Braun Dennis
Published: June 2023

Problem. The Seventh-day Adventist church continues to struggle with the issue of jewelry and adornment. Fewer members agree with the standard church teaching on the subject, and pastors and teachers are frustrated with having to continually deal with the subject, a majority of the youth in the Adventist church have rejected the traditional Adventist interpretation advocating the non-usage of jewelry. Method. This study explores the biblical texts in question, historical Adventist trends, the writings of Ellen White, and other related issues. The research results were presented in a seminar format to interested members of the College Heights Seventh-day Adventist Church. Results. The members who attended the seminar were almost unanimous in their expression of gratitude for the information that was shared. Few academy or college students attended, but this was not surprising since this subject is no longer an issue for many of them. Besides providing information on the subject matter as outlined above, considerable time was spent in discussing the conclusions and the necessity for living a principled Christian lifestyle that is inclusive of all facets of life. Conclusions. At the close of the seminar a number of observations and conclusions were shared and they are briefly outlined. The proof-text methodology does not consider the textual context. Support is lacking for the traditional Adventist teaching on the non-usage of jewelry. The Bible and Ellen White's writings need to be interpreted according to the correct hermeneutical principles. History, culture, and traditions play a significant role in our present understanding of the issue concerning jewelry. We lack a coherent understanding of terms such as: jewelry, adornment, modestly, simplicity, and worldliness. We need to be able to discern the difference between principles and standards, and accept those standards that are relevant and based upon Christian principles. Women have borne a disproportionate amount of the censure concerning the jewelry issue. Jewelry is a lifestyle issue, not a moral one, and it should not cause us to digress from our real mission of uplifting Christ. Lifestyle principles were presented which included the principles of: Love and Justice, Personal Freedom, Judgment, Stewardship, Modesty, Simplicity, Balance, and Mission. These principles should be used to determine all lifestyle choices, not just those involving jewelry and adornment.
A Seminar On The Dynamics, Prevention, And Legal Implications Of Clergy Sexual Misconduct
Authors:   ,   Andrews University, Rico Jorge
Published: June 2023

Problem Clergy sexual misconduct has become a major problem among Christian denominations. It involves violation of expectations and the breaking of public trust. There is also a growing awareness in our society of the legal implications of clergy sexual misconduct. This present study was to prepare, present, and evaluate a seminar for pastors on the dynamics, prevention, and legal implications of clergy sexual misconduct. Method Research was done to help ministers understand the dynamics, prevention, and legal implications of clergy sexual misconduct. Then, a seminar was conducted in four areas of the Oregon Conference of Seventh-day Adventists. This seminar was attended by fifty-seven pastors. Results Pastors believed that all colleges and/or the seminary should include in their ministerial training program a core course on sexual ethics in the ministry. Also, seminars and/or programs should be created to help ministers who are already serving in their respective responsibilities. They also indicated that new and transferring pastors should be screened before hiring them and be asked to attend an orientation process. Finally, the pastors expressed the hope that some fallen ministers may be given the opportunity for restoration providing that certain requirements are met. Conclusions Church leaders should study the development and implementation of an instrument to screen new and transferring pastors which includes an orientation process. Colleges and/or the seminary should consider creating and incorporating a class on sexual ethics in the ministry. Seminars/workshops should also be made available to help ministers, especially those coming from outside of North America, deal with this problem in a Christian, professional, and responsible way. Finally, more study should be done to create a system of restoration for fallen pastors and a recovery program for victims of clergy sexual misconduct, their relatives, and congregations.
