PORODICA NAMEŠTAJA – DEČIJI KUTAK
Authors: Jančić Obrad
Published: May 2022

Tema dečijeg kutka veoma je zanim­ljiva iz razloga što je potrebno pristupiti projektovanju na malo drugačiji način i odstupiti od konvencijalnog pro­jektovanja nameštaja gde su mere prilično standardi­zovane. Kod dečijeg nameštaja potrebno je isprojektovati nameštaj koji je bezbedan za korištenje (bez oštrih ivica), kao i nameštaj koji svojim merama odgovara određenom uzrastu dece. Projektni zadatak je bio isprojektovati sto i stolice za decu koje je moguće tipski proizvoditi.
Hybrid Expeditionary Service Learning Model
Authors: Udoewa Victor
Published: May 2022

Service learning is an educational model that incorporates instruction, learning, service, and reflection. Many critics have highlighted weaknesses of service learning including its inability to address structural issues, build authentic relationships with communities, assess learning, and meet community goals. Expeditionary learning is a newer learning methodology that includes a focus on social justice, provides more time for building relationships and understanding community goals, and utilizes a portfolio-based assessment approach. Because Expeditionary Learning can address some of the weaknesses of service learning, we present Hybrid Expeditionary Service Learning--a new service-learning model that employs an expeditionary learning design and embeds both the classes and service of the service-learning program within learning expeditions. The paper highlights the rationale, benefits, and mechanics of how the expeditionary learning model reinforces service learning, and also how the service-learning model can reinforce expeditionary learning.
A systemized literature synthesis of encounters with cultural differences in engineering international service-learning literature
Authors: Shermadou Amena , Delaine David
Published: May 2022

Abstract – International service-learning (ISL) has been attributed to fostering multicultural education outcomes by impacting the understanding of diversity and cultural competence in students. Within engineering education, international service-learning courses are often designed with an emphasis on engineering technical skills development. Despite the expected encounters with cultural differences, learning outcomes addressing these interactions are often an implicit focus. When not addressed, unintended consequences of these encounters can lead to increased prejudice, stereotypes, and other negative behaviors towards outgroup community members in service-learning partnerships. This manuscript presents a systemized literature synthesis of 20 papers from the engineering ISL literature in order to provide researchers and practitioners with a foundational understanding of how cultural differences have been examined or acknowledged in existing ISL work. The literature synthesis revealed the need for 1) further empirical research on encounters with cultural differences in engineering, 2) more qualitative studies exploring student experiences encountering cultural differences, and 3) a theoretical agenda that examines encounters with cultural differences within the context of engineering research and practice. The outcomes of this synthesis provide insights on research and practice that can be used to inform future work for centering encounters with cultural differences in ISL experiences in engineering.

ENVIRONMENTAL SAFETY AS A DETERMINANT OF INCLUSIVE REGIONAL DEVELOPMENT
Authors:   Chernihiv Polytechnic National University, Kharchenko Yuliia
Published: May 2022

The article analyzes the main methodological aspects of greening as a prerequisite for regional development, identifies indicators of environmental safety and sustainability, which in the author's opinion are: emissions of pollutants into the atmosphere; discharge of polluted return waters into surface water bodies, waste generation, investments in environmental protection. The strategic course chosen by Ukraine for integration into the European community requires harmonization of the institutional environment with EU countries, provided effective management decisions are made at the national, subnational and local levels, use and rational use of available resource potential to gain competitive advantage in all spheres of social development. The realities of state-building have convincingly demonstrated the need to green regional development as an unconditional requirement for the modernization of productive forces.The possibility of analyzing evaluation factors with destabilizing content and thosethat are able to balance them and to some extent improve the environmental situation is indicated.Among the previously mentioned assessment factors with destabilizing content, indicators that are able to balance them and to some extent improve the environmental situation become especially acute. Such an indicator that characterizes the ability of the regions of Ukraine to withstand pollution of air, water and other natural resources is the capacity of treatment plants.Emphasis is placed on greening as a special determinant of modernization of the institutional basis of regional development in the context of decentralization of power.It is noted that these indicators have an impact on the effectiveness of the national strategy for inclusive sustainable development.The author emphasizes that with the reduction of economic and social indicators of regional development, the presence of fierce competition, the need to intensify innovation and investment activities, including in the environmental sphere, as an important component of modernizing the productive forces of regions, effective way to equalize regional competitiveness and further development. inclusive conditions.
Equal Protection and Scarce Therapies: The Role of Race, Sex, and Other Protected Classifications
Authors: Persad Govind
Published: May 2022

The allocation of scarce medical treatments, such as antivirals and antibody therapies for COVID-19 patients, has important legal dimensions. This Essay examines a currently debated issue: how will courts view the consideration of characteristics shielded by equal protection law, such as race, sex, age, health, and even vaccination status, in allocation? Part II explains the application of strict scrutiny to allocation criteria that consider individual race, which have been recently debated, and concludes that such criteria are unlikely to succeed under present Supreme Court precedent. Part III analyzes the use of sex-based therapy allocation criteria, which are also in current use, and argues that they also face substantial legal obstacles, despite only being subject to intermediate scrutiny. Parts IV and V examine the use of age and health status in allocation. Part VI discusses how the nascent law on “vaccination status” discrimination might apply to therapy allocation.

Synopsis

Despite its demonstrated efficacy, physical activity (PA) promotion is not routinely practiced by clinicians. We provide recommendations to improve PA promotion in routine clinical practice by (1) improving clinicians' capacity through enhancing knowledge, skills, and confidence and (2) improving organizations' capacity through building PA promotion pathways. Promoting PA in routine clinical practice is urgently needed to maximize clinicians' impact on the health of society. J Orthop Sports Phys Ther 2022;52(5):236–242. doi:10.2519/jospt.2022.10859
The Common Mycelial Network (CMN) of Forests
Authors: Hildebrand Caroline
Published: May 2022

Permeating the organic layer of the forest floor is a thick, interwoven matrix composed of fine white threads of fungal hyphae collectively known as mycelium. The majority of fungal biomass dwells underground in the form of mycelium, twisting and twining through an ocean of soil. Though most people associate the word fungi with mushrooms, the sight of a mushroom marks the mere tip of the mycelial iceberg that dwells below the terrestrial surface, intermingling with plant roots, soil fauna and microbiota. It may come as a surprise that the largest organism in the world is a fungus whose mycelium spans hundreds of square miles in eastern Oregon (Stamets 2005). Despite their enormous size, even such large fungi remain invisible to the average viewer until they produce an aboveground fruiting body, often in the form of a mushroom. As such, it can be easy to overlook the essential role fungi play in the healthy functioning of every ecosystem that plants inhabit. One such role is that of the Common Mycelial Network, or Common Mycorrhizal Network (CMN). In a CMN, the root systems of plants and trees interconnect belowground via a mycelial net of symbiotic fungal partners, extending as wide as the mycelium can grow. The CMN unites multiple plant species and mycorrhizal fungi in an internet of individuals, enabling transfer of isotopic carbon, nitrogen, phosphorous, water and chemical messages between plants and fungi across species, space, and time (Simard and Durall 2004).
Digital Space & Place
Authors: Quarles Hillary
Published: May 2022

Yi-Fu Tuan gently circles space, carefully probing how humans experience the essence and liminality of place through their senses and bodies. At first thought, the idea of digital space and place – a world with no materiality – seems inconsistent with Tuan’s embodied, poetic approach. Technology eliminates any visceral experience of the world. Yet we cannot abandon our bodies. No matter where we are in digital space, our bodies remain in real and absolute space – breathing, digesting and working to be alive. This bifurcated experience of space and place is something new. It did not exist in 1977 when Tuan published Space and Place: The Perspective of Experience. What might he have written about digital space and place if he were alive today? What would he have said about how we bridge the digital and physical worlds?
Scents from Rain Forests
Authors: Kaiser Roman
Published: May 2022

Since the dawn of time, the secretive and fragile kingdom of the Rain Forest, which covers 11–13% of all emerged land and shelters eight to nine tenths of all forms of known and unknown life, has harboured extraordinary biological treasures that deserve to be treated with the utmost care. According to a further estimate, 70–80% of these species, i.e. around 60% of the entire biodiversity, is located for ecological reasons in the canopy region of the Rain Forests.Convinced that this richness would also be reflected on the olfactory level, for the past years we have searched in the understory as well as in the canopy of Rain Forests for new attractive scents. This communication opens the discussion of chemical, biological and olfactory aspects of such scents.
Enantioselective Microbial Reduction with Baker's Yeast on an Industrial Scale
Authors: Bertau Martin , Bürli Martin
Published: May 2022

Microbial synthesis is an important contribution to Green Chemistry and production-integrated environmental protection. The example of baker's yeast is used to demonstrate how microorganisms can be versatile reagents for asymmetric synthesis and how microbial technologies can be alternatives and complements to catalytic processes. The commercial viability of enantioselective microbial processes on an industrial scale is shown with the examples of (S)-3-hydroxybutyric acid ethylester (1), (2S,5S)-hexanediol (2) and (1R,2S)-cis-2-hydroxycyclohexane carboxylic acid ethylester (3). The investigation of several competing enzymatic pathways in the living cells during the reduction reaction allows the process to be controlled and makes this technology applicable for the large-scale commercial synthesis of 3.
Waste Reduction in Alkyl Pyridine Production: Solving the Root Problem Pays off
Authors: Gerritzen Detlef
Published: May 2022

The production process for 5-ethyl-2-methyl-pyridine (MEP) is the largest single source of total organic carbon and total nitrogen in the feed of the capacity-limited wastewater treatment plant at LONZA's major production site. According to LONZA's integrated waste treatment concept,
efforts were made to reduce the amount of critical components in the MEP process wastewater. Detailed analysis of causes and effects revealed the formation of small amounts of ethylamines in the reaction unit as the root cause not only for the ecological but also for the economical problems
such as high catalyst consumption and reduced MEP yield. Separation of interfering ethylamines from the process in combination with recycling of catalyst and catalyst byproduct-containing process water can solve all problems.

Authors: Rojas Ramírez José Juan Pablo , González Villa Sandra
Published: May 2022

El objetivo del presente es analizar las implicaciones de la pandemia covid19 en la dinámica de movilidad y transporte durante la disrupción en Guadalajara, México, así como los efectos de la estrategia de las instituciones públicas. Los eventos pandémicos ocasionan disrupciones en la movilización urbana y transporte de la ciudadanía, que pueden alterar las dinámicas económicas y producir efectos negativos en la percepción de ingreso en los hogares con lo que se agrava el esquema de desigualdad social en una metrópoli que aparentemente goza con un Índice de Desarrollo Humano elevado. Metodológicamente, se recurrió a los enfoques de Estudio de Caso, el análisis estadístico descriptivo, análisis de la acción pública y sociología de la vida y realización de trabajo de campo. Entre los principales hallazgos se encontró que las restricciones de movilidad en un área metropolitana a través del confinamiento social y el cierre selectivo de actividades productivas y la reducción del servicio de transporte público incrementó el uso de transporte privado; además, la estrategia del confinamiento social metropolitano, en particular el “ el botón de emergencia”, provocó concentraciones altas de usuarios del transporte público en horarios de servicio reducido por disposición oficial de la estrategia de contención, lo cual, propició el incremento del riesgo de infección aunado al perdida o reducción de ingreso económico necesario para solventar necesidades básicas

The Shaman Kim Keum Hwa - Korea’s National Treasure
Authors: Погадаева Анастасия Викторовна
Published: May 2022

В статье рассматривается шаманизм в Корее - мусок. В первой части выделяются основные особенности данного явления, а также перечисляются работы на русском языке, в которых коротко или более подробно рассказывается о корейском шаманизме. Но главный акцент в статье делается на роли профессионального посредника, медиатора между миром людей и миром духов - шаманом мудан, которым в Корее, как правило, является женщина. На протяжении истории Кореи положение шаманок и отношение к ним со стороны государства менялось, а их социальное положение было невысоким. Во второй части статьи на примере биографии известной шаманки Ким Кымхвы анализируется статус шаманок в XX в. В первой половине столетия отношение к мудан остается сложным. Во время японского господства, а также во время Движения за новую деревню они даже подверглись серьезным гонениям. В 1970-е гг. ситуация начинает меняться: фольклористы и этнографы проявляют большой интерес к шаманизму. Шаманские обряды признаются государством. Теперь шаманизм в Корее больше воспринимается как часть национальной культуры и самоидентификации, а не религиозного культа. Исследование актуально в свете изучения корейского шаманизма и его современного положения на Корейском полуострове. Материалы о шаманке Ким Кымхвы представлены на русском языке впервые.

This article is focused on “musok.” Korean shamanism. It highlights the main features of this phenomenon, and also lists works in Russian that discuss Korean shamanism and describe the role of the shaman-mudang. The shaman is a professional mediator between the world of people and the world of spirits, who in Korea is usually a female. In the course of Korean history, the position of shamans and the attitude of the state towards them has changed, although their status was usually low. In the second part of the article, the author analyzes the changing position of shamans in the twentieth century based on the example of the famous shaman Kim Keum Hwa. In the first half of the century, the attitude towards mudangs was complex. Under Japanese rule, as well as during the movement for the New Village, they were severely persecuted. In the 1970s the situation began to change, as folklorists and ethnographers showed great interest in shamanism. Shamanic rituals were recognized at the state level. Now shamanism in Korea is perceived as a part of national culture and self-identification, and not as a religious cult. The article is relevant in light of the study of Korean shamanism and its current situation on the Korean Peninsula. Material about Kim Keum Hwa is presented in Russian for the first time.

Metamorphosis of activated nitrogen to ammonia at metal-free ambient condition: A DFT based inquisition
Authors: Logdi Ratan , Bag Arijit , Tiwari Ashwani Kumar
Published: May 2022

Activation of N_2 at an ambient condition and reduction to produce ammonia employing metal-free catalyst is one of the grand scientific problems to date. An effective appetite of carbenes towards molecular nitrogen proclaims their candidature as N_2 sequestering agent. However, the sequestering process is associated with a high activation energy barrier. Thus, to ameliorate the use of carbene for the N 2 activation process a Density Functional Theory (DFT) based design is pursued. Through a systematic study, the binding mechanism of the C − N bond between carbene and nitrogen is explored to model efficient carbene. Additionally, Intrinsic Reaction Coordinate (IRC) geometry traping followed by molecular orbital analysis was employed to explore the electronic level reaction mechanism of diazo derivative formation. It is corroborated that in the carbene − N_2 reaction, carbene operates as a σ -acceptor and π-donor where the bonding and the back bonding processes take place before and after the transition state of the reaction. With the aid of this knowledge, a model carbene is designed and computationally tested for nitrogen activation and ammonia formation. It is observed that the model carbene, 6^CN , is an efficient candidate for nitrogen activation and ammonia synthesis in a catalytic way. These results may stimulate future experimental inquisitions.
The microkinetics of ammonia synthesis: the effect of surface coverage on apparent activation energy and reaction order
Authors: Morimoto Ryusei , Ogawa Takaya
Published: May 2022

We investigated the coverage effect on the experimental results using Ru and Ru+K for ammonia synthesis at 0.1 MPa and 380~460℃. Especially for Ru+K, the reaction order changed significantly with temperature, and the rate-limiting step was also affected by temperature. The apparent activation energy decreased as the gas flow rate decreased, even when the total pressure was the same. We showed through experimental techniques that even relatively small changes in experimental conditions on a laboratory scale can change the coverage and have a non-negligible effect on the reaction order and apparent activation energy.
Beneficial vs. Inhibiting Passivation by the Native Lithium Solid Electrolyte Interphase Revealed by Electrochemical Li+ Exchange
Authors: M. Hobold Gustavo , Kim Kyeong-Ho , Gallant Betar M.
Published: May 2022

Despite being a leading candidate to meet stringent energy targets of Li-ion batteries, the lithium (Li) metal anode has yet to achieve Coulombic efficiency (CE) requirements for long cycle life (>99.9%), particularly at high rates (>1 C). These limitations derive from the native solid electrolyte interphase (SEI) which, among multiple functions, stabilizes and protects deposited Li. The SEI also plays a critical role in regulating Li+ exchange between the electrolyte and the electrode, but quantification of this effect has been non-straightforward, and a general relationship between Li+ exchange and CE has not been clearly elucidated to date. Using electrochemical impedance and voltammetry, we report self-consistent Li+ exchange values of native SEIs over a range of relevant electrolytes with CE spanning 78.0% to >99%. CE and its retention at high rates are found to be positively correlated with the rate of SEI Li+ exchange. Additionally, Li+ exchange rates increased during cycling in high-CE electrolytes, in some cases by an order of magnitude to exceed 10 mA/cm2, whereas for low-CE electrolytes they remained low (<1 mA/cm2), revealing a chemistry-dependent picture of SEI evolution with often-complex dynamics. The evolution in Li+ exchange unique to high-CE electrolytes also provides insights into the role and effectiveness of the formation cycle on Cu current collectors upon the first plating step. Altogether, these findings indicate that Li+ exchange governs several key processes related to Li deposition and cycling efficiency. Consequently, its quantification can help to guide future high-CE electrolyte design, particularly targeting high rates (>1 mA/cm2).

Authors: Pankratova Ekaterina S. , Chernenkov Yurii V. , Panina Olga S. , Kurmacheva Natalia A. , Kuznetsova Natalia A. , Pylaev Timofey E.
Published: May 2022

Background. Preterm infants are at high risk for respiratory distress and vitamin D deficiency, which may be associated with a need for intensive care and long-term respiratory support.
Aim. To study the features of respiratory disorders and vitamin D status in preterm infants with a gestational age of more than 32 weeks.
Materials and methods. The object of the study were 64 moderate and late preterm infants with respiratory disorders and their mothers. The level of 25(OH)D in cord blood serum was determined by enzyme immunoassay.
Results. 60.9% of children were diagnosed with respiratory distress syndrome (Group 1), 39.1% had congenital pneumonia (Group 2). Mothers of all children had a high incidence of chronic diseases and pregnancy complications. Hypovitaminosis D was detected in 71.888% of newborns of both groups, mainly at the stage of deficiency. The median concentrations of 25(OH)D in cord blood serum were 15.41 [12.4934.25] ng/ml in the 1st group of newborns, and 18.42 [14.0123.44] ng/mL in the 2nd group. The need for exogenous surfactant administration and CPAP respiratory therapy is significantly higher in neonates with respiratory distress syndrome. Children with congenital pneumonia significantly more often required mechanical ventilation, and they also had a longer total duration of respiratory support in the form of humidified oxygen supplementation. The duration of inpatient treatment in children of both groups with hypovitaminosis D was significantly higher compared to newborns with adequate levels of vitamin D.
Conclusion. Moderate and late preterm infants with respiratory problems should be identified at high risk for hypovitaminosis D, screened for blood levels of 25(OH)D, and developed optimal vitamin D supplementation regimens a promising direction to reduce the risk of preterm birth, neonatal morbidity and reduce the time of inpatient treatment of respiratory disorders.

Manual harvesting (sickle), a most common practice for majority of the farm households is a labour and time intensive practices in Nepal. Therefore, there is need of harvesting mechanization option suitable for smallholder farmers to replace the manual harvesting of rice. Hence, a study was conducted to evaluate the performance of a self-propelled reaper, originally developed in China, under local farmer field condition in Lalitpur district. Reaper was evaluated in terms of different performance parameters such as field capacities, field efficiency, fuel consumption, harvesting grain loss, and associated harvesting labour and cost. The average effective field capacity of the reaper (machine harvesting) was obtained as 0.13 ha/h with a field efficiency of 68.69 % at an average operating speed and wheel slip of 1.72 km/hr and 5.46%, respectively while that of sickle harvesting (manual method) was 0.0084 ha/hr. The average fuel consumption of selfpropelled reaper was obtained as 1.32 L/h. The average grain harvesting losses of 1.36% and 1.73 % were found in machine harvesting and manual harvesting. A labour saving of 93.54 % was achieved by the use of reaper (7.7 man–hr/ha) compared to manual harvesting (119.08 man-hr/ha). Manual harvesting needs almost 15.47 hours to harvest equal area as that by reaper in one hour. Likewise, cost saving of 30.01 % was occurred in custom hired machine harvesting (NRs 5384 /ha) with respect to manual method (NRs 7693/ha). Considering economic perspectives, the reaper becomes profitable only after 104.04 h of annual machine use which is equivalent to 13.6 ha of rice harvesting at a machine field capacity of 0.13 ha/hr with respect to investment cost of NRs 1, 80,000 and hiring charge at NRs 700 per hour. The benefit cost ratio (B/C ratio) was found out to be 1.77. The Payback period (PBP) was calculated to be 1.22 years. It can be concluded that small size reaper has possibility of becoming one of the suitable harvesting technology (custom hiring) for hilly and mountainous areas of Nepal where sickle harvesting is currently followed.

Rapid population growth and high rate of urbanization make municipal solid waste management a challenging task for municipalities. Lack of sufficient infrastructural facilities worsen this challenging situation. To curb this, transfer stations, which are facilities located close to residential areas and are used to receive and hold waste temporarily until it is transported to distant landfills. It reduces waste transportation cost and provide a place for waste segregation. In Lahore open transfer station is built near river Ravi and residential areas which is creating air and land pollution. This study is carryout to select the suitable location for waste transfer station in Lahore that meets the USEPA criteria. Buffer command of Arc GIS is used for site selection. Best suitable sites selected for Lahore in this analysis are UC Sultanki and UC Chandrai where more buffers are joint during buffer analysis. Furthermore, cost estimation for the construction and operation of both waste transfer stations are done.

The purpose of this study was to examine the load of
regular players and floater players in a specific small-sided game. Twenty semi-professional
soccer players performed one 4vs4+2, modifying the position of the floaters
(internal, external, zone, square and without floaters). Total distance
covered, distance covered at speeds between 7-13.9 km·h−1, 14-17.9
km·h−1, and ≥18 km·h−1, accelerations and decelerations
between 2.5-4 m·s−2, maximal and mean heart rate (HR) and
rating of perceived exertion (RPE) were
analyzed. Internal floaters achieved greater total distance covered,
accelerations and RPE than in any other
position. Internal and external floaters achieved more distance covered at 7-13.9,
14-17.9, >18 km·h-1 and HR than zone and square floaters. With
internal floaters, regular players covered more distance covered >18 km·h-1
than in any other 4vs4+2 format, and with internal and external floaters regular
players covered greater total distance and distance at 14-17.9 km·h-1 than
without floaters or with zone or square floaters. Regular players showed greater
total distance covered, distance covered at 7-13.9, 14-17.9, >18 km·h-1,
accelerations and RPE than floaters in all 4vs4+2.
These data showed that floater
position in 4vs4+2 game influenced the internal and external load of
both the regular players and the floaters.
Bayesian Confidence Interval for Ratio of the Coefficients of Variation of Normal Distributions: A Practical Approach in Civil Engineering

Published: May 2022

The coefficient of variation (CV) is a useful statistical tool for measuring the relative variability between multiple populations, while the ratio of CVs can be used to compare the dispersion. In statistics, the Bayesian approach is fundamentally different from the classical approach. For the Bayesian approach, the parameter is a quantity whose variation is described by a probability distribution. The probability distribution is called the prior distribution, which is based on the experimenter’s belief. The prior distribution is updated with sample information. This updating is done with the use of Bayes’ rule. For the classical approach, the parameter is quantity and an unknown value, but the parameter is fixed. Moreover, the parameter is based on the observed values in the sample. Herein, we develop a Bayesian approach to construct the confidence interval for the ratio of CVs of two normal distributions. Moreover, the efficacy of the Bayesian approach is compared with two existing classical approaches: the generalised confidence interval (GCI) and the method of variance estimates recovery (MOVER) approaches. A Monte Carlo simulation was used to compute the coverage probability (CP) and average length (AL) of three confidence intervals. The results of a simulation study indicate that the Bayesian approach performed better in terms of the CP and AL. Finally, the Bayesian and two classical approaches were applied to analyse real data to illustrate their efficacy. In this study, the application of these approaches for use in classical civil engineering topics is targeted. Two real data, which are used in the present study, are the compressive strength data for the investigated mixes at 7 and 28 days, as well as the PM2.5 air quality data of two stations in Chiang Mai province, Thailand. The Bayesian confidence intervals are better than the other confidence intervals for the ratio of CVs of normal distributions. Doi: 10.28991/CEJ-SP2021-07-010 Full Text: PDF

Indonesia is a super cultural power country, rich in customs and culture line from Sabang to Merauke, from Nias to Rote Island. Cultural wealth breeds architectural diversity. The potential of original Indonesian architecture has begun to be left behind and eroded by foreign cultures. The postmodern era has raised Nusantara Architecture to the world stage. Researches on the wealth of Nusantara architecture begin to bloom like mushrooms in the rainy season. The phenomenon of the skills or expertise of the masters has made traditional houses an endless research material. The purpose of this research is to explore the treasures of the Indonesian nation's wealth, especially the craftsmanship skills of Indonesian ancestors. The phenomenon of tying, knitting, and stringing materials into architectural masterpieces is a uniqueness and uniqueness that other nations do not have. The method used in this study uses the phenomenological method. Where in the vernacular architectural phenomenology is divided into two branches; first: related to space, place, and atmosphere, second: related to tectonic or the art of construction more on the elements of craftsmanship. The results of this study reveal that simple and straightforward technology becomes effective when it comes to craftsmen who have special skills. The conclusions of this study indicate that the skill of the masons is more dominant than the tools used, on the other hand, currently tools are more dominant than the skills of the masons.
