Filosofia do desenvolvimento como filosofia dos países subdesenvolvidos
Authors: Da Costa Breno Augusto
Published: June 2024

The aim of this paper is to present the philosophy of development as proposed by the Brazilian philosophers Álvaro Vieira Pinto (1909-1987) and Roland Corbisier (1914-2005). Departing from the examination of some of the main texts from those authors, we show that instead of a mere philosophical discourse on development, this proposal constitutes an autonomous philosophical science and that it takes as its main subject the condition of existence of collectivities. From philosophy of development emerges a paradigmatic platform that supports an ethics of development, a politics of development, an education of development, a sociology of underdeveloped countries and others that will be briefly presented, just as some of the main thesis and concepts underlying this science. We conclude indicating some future research lines.

Ho Chi Minh’s Ideology on the Rule of the Law State and the Meaning of That Ideology in Building the Rule of the Law State in Vietnam Today
Authors: ThiNguyen NhiLien
Published: June 2024

The idea of the rule of law is always associated with the idea of democratic development that has been established since ancient times. This ideology exists and develops to this day and has become a symbol of democracy. Ho Chi Minh’s Ideology on the rule of law is the inheritance of cultural traditions and the experience of building and managing the state of many generations of Vietnamese people, and is the result of experience, research, and survey of many world democratic ideological systems, many revolutions, and many typical states in the world; at the same time, the penetration and creative application of the Marxism-Leninism’s perspective on a new style state to the specific conditions of Vietnam. This study has shown that with the nature of the people’s democratic revolution, stemming from the reality of a semi-feudal colonial country like Vietnam, the Communist Party of Vietnam (CPV) and President Ho Chi Minh has chosen the path of building a socialist rule of law state in Vietnam. Ho Chi Minh’s comprehensive and profound views on the rule of law are extremely great and valuable “spiritual assets”, laying the ideological and theoretical foundation for the policy of “continuing to build and perfecting the socialist rule of law state in Vietnam” of CPV today.

Published: June 2024

Tomatoes, tsunga (mustard) and rape were sampled from Mashonaland East and Central provinces of Zimbabwe. Aim was to assess hyper accumulative tendency of these towards heavy metals (Cd, Cu, Co, Cr, Ni, and Pb). Most of these heavy metals were noted to be of anthropogenic origin. Co, Mn and Cr were noted to be naturally inherent in Mushimbo, Mutoko soils. Heavy metal levels in irrigation water were within internationally acceptable ranges according to ATSDR. There was no direct reflection of level dependency between the water and plants studied. Bioaccumulation of cadmium and lead levels occurred in all vegetables despite low levels in the soil environment. High heavy metal levels in arable land as compared to virgin land proves contamination at play and also the anthropogenic origin. It was concluded that different vegetables accrue different heavy metals at different rates under the same environment. It was recommended to do more investigations on factors that determine absorption and hyper accumulation tendency of heavy metals in plants. This data could be used as a basis for recommending what crops to grow and in specific areas hence promote food safety in addition to food security for the nation.

Published: June 2024

The poraquê has an elongated and cylindrical body, with just one anal fin, which extends across almost the entire abdomen it resembles the shape of an eel. Its head is flat and its mouth is equipped with a row of sharp, conical teeth. The color of this animal is always very dark, but the ventral part of the body is yellowish and they have poor vision. This group of fish is known for their ability to generate and detect electrical fields in the environment in which they occur, and these characteristics are used in communication, prey detection, defense, reproduction and even to help these animals move in the absence of light. This manuscript aims to describe the biology, ecology, morphology, geographic distribution, life cycle, habitat, and therapeutic use of electric fish (Chordata: Actinopterygii: Gymnotiformes). Concerned with establishing a public profile of quality research in the area, we sought to answer these questions based on a literature review in the main journals (national and international) classified by the Coordination for the Improvement of Higher Education Personnel (CAPES). Complement this analysis with other documents such as books, theses, dissertations, scientific journals, documents, and digital platforms.

Authors: Halder Dr. Dalia , Alam Dr. Md. Iskander , Ferdous Dr. Zinnia , Akhter Dr. Afsana
Published: June 2024

Background: Labor pain is intensely severe, often leading to hyperventilation and hormonal releases that can harm the fetus by reducing oxygen supply and causing metabolic acidosis. Effective pain management during childbirth is crucial for both physical and mental health. Various pharmacologic and non-pharmacologic methods are available, with epidural analgesia being a prominent choice. It is widely used in high-income countries, provides substantial pain relief, and benefits uterine contractions and placental perfusion. Epidural analgesia has potential side effects and controversies, such as delayed labor and higher intervention rates. Aim of the Study: The study aimed to examine the impact of epidural analgesia on the mode of delivery. Methods: This observational study, conducted from July 2021 to June 2022 at the Department of Gynecology and Obstetrics in a 250-bed District Hospital in Bagerhat, Bangladesh, included 50 participants divided into two groups of 25 each: Group A (with epidural analgesia) and Group B (without epidural analgesia). Approved by the Ethical Committee, the study included women aged 18-35 years, 37-41 weeks gestation, in labor with regular contractions, at least 4 cm cervical dilatation, and a regular fetal heart rate pattern. Excluded were women with medical or obstetrical complications, uterine scars, or spinal deformities. Data were collected via interviews, observations, and clinical examinations. Result: In this study of 50 participants (25 per group), most women were under 30 years old, with mean ages of 22.4±4.5 and 22.9±5.2 years in groups A and B, respectively. Gestational ages ranged from 37 to 40 weeks, and BMIs were 18.5-24.9 kg/m². Both groups had similar parity distributions. Normal vaginal births occurred in 84% (Group A) and 88% (Group B), with LSCS rates at 4%. Group A had 60% male neonates with average birth weights of 2.86±0.27 kg, and Group B had 56% males with weights of 2.88±0.26 kg. APGAR scores were high in both groups. Conclusion: Epidural labor analgesia is safe and does not increase instrumental deliveries or affect neonatal outcomes, making it a viable pain management option. Obstetric care providers can use this information to counsel women.

Este artigo examina a interconexão entre a alimentação e a saúde da mulher, abordando diversos aspectos desde a saúde reprodutiva até a saúde óssea e cardiovascular. Uma revisão abrangente da literatura revelou que uma dieta balanceada desempenha um papel crucial na prevenção de doenças crônicas e na promoção do bem-estar feminino. Os resultados destacam a importância de nutrientes específicos, como ferro, cálcio e ácidos graxos ômega-3, na saúde reprodutiva e na fertilidade. Além disso, padrões alimentares saudáveis, como a dieta mediterrânea, demonstraram reduzir o risco de doenças cardiovasculares e câncer de mama em mulheres. Desse modo, estratégias de intervenção dietética, como o aumento do consumo de frutas, vegetais e alimentos ricos em fibras, foram recomendadas para melhorar a saúde óssea e prevenir a osteoporose. Considerações sobre a saúde mental também foram abordadas, com evidências emergentes sugerindo que certos nutrientes podem influenciar positivamente o bem-estar emocional das mulheres. Assim, este artigo enfatiza a importância da educação alimentar, acesso equitativo a alimentos saudáveis e políticas públicas voltadas para a promoção de hábitos alimentares saudáveis entre as mulheres. São necessárias mais pesquisas para elucidar os mecanismos pelos quais a alimentação afeta a saúde feminina e desenvolver intervenções eficazes baseadas em evidências.

O estudo possui como objetivo identificar as intervenções que alteram o desfecho da fase aguda do AVC.  A presente pesquisa trata-se de uma revisão integrativa da literatura. Para tal estudo, foi construída a seguinte pergunta norteadora: “Quais as intervenções que alteram o desfecho da fase aguda do AVC.?”. Na elaboração da pergunta norteadora e na busca de evidências científicas utilizou-se a estratégia PICO, que possui o seguinte significado: P de paciente ou população; I de intervenção ou indicador; C de comparação ou controle e O de outcome que significa o desfecho clínico, resposta ou resultado sendo o que se espera encontrar nos estudos selecionados. Após a combinação dos descritores nas bases de dados e a aplicação rigorosa dos critérios de inclusão e exclusão, foram elegidos 11 artigos. A fase aguda do Acidente Vascular Cerebral é um período crítico em que intervenções rápidas e eficazes podem significativamente alterar os desfechos clínicos dos pacientes. Estudos científicos têm demonstrado que tratamentos como a trombólise intravenosa e a trombectomia mecânica endovascular são fundamentais para melhorar os resultados pós-AVC, reduzindo a incapacidade e aumentando a independência dos pacientes. As intervenções na fase aguda do Acidente Vascular Cerebral representam um marco significativo na melhoria dos desfechos clínicos para pacientes acometidos por esta condição. A administração rápida e eficaz de tratamentos como a trombólise intravenosa e a trombectomia mecânica endovascular tem mostrado, de forma consistente, reduzir a incapacidade e aumentar a independência funcional dos pacientes após um AVC. A evidência científica robusta demonstra que a restauração rápida do fluxo sanguíneo cerebral, seja por dissolução química do coágulo ou remoção mecânica, é crucial para minimizar o dano neuronal e melhorar os resultados a longo prazo. No entanto, a elegibilidade para esses tratamentos é limitada por fatores temporais e clínicos específicos, o que sublinha a necessidade de uma triagem precisa e protocolos de atendimento emergencial rigorosos.

As doenças neurodegenerativas, como a doença de Alzheimer (DA) e a doença de Parkinson (DP), são desafios significativos para a saúde global devido a suas altas prevalências e impactos debilitantes. Essas condições são influenciadas por complexa interação de fatores genômicos, epigenéticos, metabólicos e ambientais. O diagnóstico tardio e as terapias focadas apenas nos sintomas contribuem para a limitada eficácia dos tratamentos atuais. No entanto, as abordagens epigenéticas emergem como promissoras, oferecendo novas perspectivas para a detecção precoce e o tratamento de doenças neurodegenerativas. Modificações epigenéticas, como metilação do DNA e alterações na cromatina, desempenham papel crucial na regulação da função neuronal e na patogênese dessas doenças. Este artigo revisa os avanços recentes na compreensão dos mecanismos epigenéticos envolvidos na neurodegeneração e destaca potenciais estratégias terapêuticas baseadas em epigenética que podem oferecer novos horizontes para o diagnóstico e o tratamento dessas doenças.

On the stability of rotation in an environment with resistance of a free system of two elastically connected rigid bodies
Authors: Kononov Yuriy
Published: June 2024

The equations of rotation in a medium with resistance of a free system of two rigid bodies connected by an elastic spherical joint or Hooke's joint are obtained. Under the assumption that the center of mass of solid bodies is located on the third axis of inertia, equations of perturbed motion are obtained. These equations are represented as eight ordinary differential equations with periodic coefficients. For two Lagrange gyroscopes, a fourth-order characteristic equation is obtained. Based on the Liénard-Schipart criterion, written in the form of innors, conditions for the asymptotic stability of uniform rotations of Lagrange gyroscopes are obtained. These conditions are presented in the form of three inequalities. Analytical studies of stability conditions were carried out. It has been proven that the first inequality is always satisfied. From the third inequality it follows that if the gyroscopes have equal axial moments of inertia and rotate with the same angular velocities in different directions or there is no elasticity in the hinge, then the characteristic equation has a multiple root. In this case, the issue of sustainability requires additional research. The conditions for stability in terms of kinetic moments are written out and it is shown that the leading inequality coefficients are positive, from which it follows that stability will always be possible for sufficiently large values of one or two kinetic moments. Similar conclusions were obtained with the Hooke's hinge, and it was also shown that with identical gyroscopes the characteristic equation splits into two equations. In the absence of elasticity, a multiple zero root appears in the hinge and stability requires additional study.
Asymptotic estimates for deviations of Fejér means on Poisson integrals
Authors: Rovenska Olga
Published: June 2024

The work is devoted to the investigation of problem of approximation of continuous periodic functions of a real variable by trigonometric polynomials generated by linear methods of summation of Fourier series. The simplest example of the process of linear approximation of periodic functions is approximation of functions by partial sums of their Fourier series. However, sequences of partial Fourier sums are not uniformly convergent on the whole class of continuous periodic functions. Therefore, numerous studies are devoted to the study of approximation properties of approximating methods, which are generated by different transformations of sequences of partial sums of the Fourier series and allow obtaining sequences of trigonometric polynomials that are uniformly convergent for the entire class of continuous functions. In particular, Fejér means have been intensively studied in recent decades. One of the important tasks in this direction is study of the asymptotic behavior of the upper bounds of the deviations of trigonometric polynomials for a fixed class of periodic functions. The aim of the work is to systematize the known results concerning the approximation of classes of periodic functions of high smoothness by arithmetic means of Fourier sums, and to present new facts obtained for a more general case. In paper we investigate the asymptotic behavior of upper bounds on classes of Poisson integrals of periodic functions of real variable of deviations of linear means of Fourier series, which are constructed using the Fejér summation method. We study the classes consist of analytic functions of a real variable, which can be regularly extended into the corresponding strip of the complex plane. In the work, asymptotic inequalities for the upper bounds of the deviations of the Fejér means on the class of Poisson integrals were found. In certain case of parameters defining the class, the obtained formulas coincide with previously known asymptotic equalities.

Analysis of the Role of Vitamin C Hypovitaminosis in Scurvy on Bone Health: A Single Center Observational Study at Dr. Moewardi General Hospital, Surakarta, Indonesia
Authors: Nefihancoro Udi Heru , Rachmad Faisal
Published: June 2024

Background: Scurvy, vitamin C deficiency, is a rare condition but remains relevant in Indonesia. This study aims to analyze the role of vitamin C hypovitaminosis in the development of scurvy and its impact on bone health through an observational study at Dr. Moewardi General Hospital. Surakarta.
Methods: A cross-sectional observational study was conducted on 30 patients diagnosed with scurvy at Dr. Moewardi General Hospital Surakarta during the 2020-2023 period. Demographic data, medical history, nutritional status, and severity of scurvy were collected. A radiological examination of the bone is performed to assess scurvy-related changes. Descriptive, comparative, and Spearman correlation statistical analyzes were used.
Results: The majority of patients were men (66.7%) with a mean age of 45 years. A history of an unbalanced diet with low fruit and vegetable intake was found in the majority of patients (86.7%). Common symptoms include fatigue (86.7%), joint pain (73.3%), bleeding gums (60%), and skin bleeding (53.3%). The severity of scurvy varied, with 10 patients (33.3%) experiencing severe scurvy. Radiological examination shows significant changes in long bones, especially osteoporosis and thinning of the cortex, which is more obvious in patients with severe scurvy. Spearman correlation analysis showed a positive correlation between the severity of scurvy and the incidence of osteoporosis (rho = 0.495, p = 0.005) and cortical thinning (rho = 0.394, p = 0.031).
Conclusion: Vitamin C hypovitaminosis plays a significant role in the development of scurvy and has a negative impact on bone health. Early screening and diagnosis of scurvy are important to prevent musculoskeletal complications. Nutritional education and dietary interventions to increase vitamin C intake need to be intensified, especially in high-risk groups.

Published: June 2024

Aim: The aim of this work was to study the effects of extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) on inflammation-impaired cognitive functions and the brain of mice.
Methods: Young mice (~3-month-old) and aged mice (~18-month-old) were injected with bacterial lipopolysaccharide (LPS) and obtained intravenously donor 106 human umbilical cord MSCs, EVs isolated from a similar amount of MSCs or conditioned medium (CM) of MSCs. Subsequently, the mice were examined in behavioral tests and the mouse brains were analyzed for the levels of pro-inflammatory cytokines, α7 nicotinic acetylcholine receptors (α7 nAChRs) and amyloid beta 1-42 (Aβ1-42).
Results: EVs prevented LPS-induced memory impairment in mice, whereas CM provided a weaker and temporal effect. Both EVs and MSCs injected once after regular injections of LPS stably improved memory of young mice. In contrast, both cells and EVs provided only transient effect in aged mice injected with LPS. The brains of aged LPS-treated mice contained elevated amounts of IL-1β and IL-6; both MSCs and EVs decreased them significantly. The brains of non-treated aged mice contained decreased levels of α7 nAChRs and increased levels of Aβ1-42 and α7-bound Aβ1-42 compared to the brains of young mice. LPS treatment decreased α7 nAChRs in both young and aged mice, while both MSCs and EVs restored them up to the control level. In young mice, LPS treatment increased the level of Aβ1-42 and α7-bound Aβ1-42, whereas MSCs and EVs decreased it. In contrast, neither LPS nor MSCs/EVs influenced the elevated level of Aβ1-42 but increased α7-bound Aβ1-42 in the brains of aged mice.
Conclusions: Regenerative potential of MSCs and MSC-derived EVs is sufficient to support cognitive functions of LPS-treated young mice but is quite poor for aged animals, possibly, due to decreased levels of α7 nAChRs and accumulated Aβ1-42 in their brains.

Pesatnya perkembangan pembangunan kota memicu terjadinya kelangkaan lahan akan tempat tinggal bagi masyarakat. Ketidakmampuan akan penyediaan lahan-lahan permukiman baru juga memicu berkembangnya kawasan-kawasan permukiman yang tidak sesuai dengan peruntukan lahannya. Adapun salah satu contoh yang lazim ditemukan dari fenomena perubahan guna lahan ialah tumbuhnya permukiman kumuh di sempadan sungai. Kawasan bantaran sungai Krueng Daroy, Kecamatan Darul Imarah, Kabupaten Aceh Besar mengalami permasalahan terkait ketidaksesuaian penggunaan lahan berupa berkembangnya permukiman kumuh di bantaran sungai sejak tahun 1989 hingga saat ini. Hal yang sangat mengkhawatirkan adalah kawasan ini merupakan kawasan yang mengalami kerentanan akibat ancaman banjir sepanjang tahun. Penelitian ini bertujuan untuk mengidentifikasi karakteristik permukiman kumuh di bantaran Sungai Krueng Daroy melalui identifikasi terhadap pola perkembangan spasial kawasan permukiman kumuh dan aspek fisik dan non fisik yang membentuk kawasan kumuh di bantaran Sungai tersebut serta menelusuri faktor pemicu berkembangnya permukiman kumuh di kawasan tersebut. Penelitian ini menggunakan metode kuantitatif deskriptif untuk menemukan karakteristik serta faktor yang mendasari terbentuknya permukiman kumuh melalui observasi dan kuisioner terhadap persepektif masyarakat terkait permukiman kumuh. Hasil dari penelitian menunjukkan bahwa pola penggunaan lahan eksisting yang berada di kawasan sempadan sungai Krueng Daroy didominasi aktivitas permukiman dengan kondisi permukiman yang tidak sesuai dengan standar rumah layak huni. Adapun faktor yang berpengaruh terhadap timbulnya kawasan kumuh di Krueng Daroy adalah faktor demografi, sosial ekonomi, akses terhadap fasilitas publik, preferensi, regulasi, sosialiasi serta partisipasi masyarakat dalam menyusun arahan rencana tata ruang. Diharapkan dengan adanya penelitian ini akan membuka gagasan bagi studi lanjutan untuk memberikan rekomendasi terkait penyelesaian permasalahan kumuh di kawasan Krueng Daroy agar kawasan sungai tetap terjaga serta membuka opsi kepada masyarakat agar dapat hidup dengan layak pada area permukiman yang direkomendasikan nantinya.

Mr. Muhammad Hasan is street one of the entrance gates to Banda Aceh City. The condition of the road is in steady condition, with a two-lane, two-way type divided with a median of 1.5 m wide. The role of this road is very strategic, considering that if a tsunami occurs, this road is one of the community's escaped roads. The results of initial observations of this road are still in a comfortable condition to drive, but it is necessary to research the level of service to anticipate its role as an escape road. Based on that, we want to know how the level of service on Jalan Mr. Muhammad Hasan. The purpose of this study was to determine the level of service Jalan Mr. Muhammad Hasan using the 1997 MKJI method. Data were collected through a survey of traffic volume and speed for 3 (three) days, namely Thursday, Friday and Sunday. The duration of the survey is 07.00-18.00 with 8 (eight) surveyors. The traffic volume is multiplied by the number emp, so we get the amount of flow at peak hours in the morning, afternoon and evening. The result of recording speed in m/second is converted to km/hour. Furthermore, the capacity of city roads, free flow speed and degree of saturation is calculated. Based on the value of capacity, speed and degree of saturation, the value of road service level is obtained. Based on the calculation results, the highest peak hours on observation day occurred in the afternoon, namely Thursday at 15.45-16.45 (2144 p.m./hour), Friday at 16.15-17.15 (2295 p.m./hour) and Sunday at 17.00-18.00 as many as 1698 smp/hour. hour. The capacity of the road on the three observation days was 6178 pcu/hour and the speed was 53.01 km/hour. The lowest degree of saturation occurred on Sunday afternoon at 0.18 and the highest occurred on Friday at 0.54 and overall it was still below 0.75 so there was no need for a scenario. The level of service in the morning and afternoon (Thursday, Friday, Sunday) still shows a value of A, while on Monday afternoon it becomes C and on Friday and Sunday it slightly decreases to B.

Pasir laut menjadi pilihan yang banyak digunakan oleh masyarakat pesisir dan kepulauan, karena sulitnya sumber atau penambangan pasir sungai, maka pasir laut menjadi suatu alternatif sebagai sumber material yang cukup dekat, sehingga dapat diperoleh dengan mudah. Meskipun pemakaian pasir laut memiliki beberapa kekurangan seperti menyebabkan korosi pada tulangan. Pozzolan merupakan material yang masih terlalu kurang penggunaannya, namun kandungan yang dimiliki pozzolan mampu menjadi bahan pengikat sebagai pengganti semen, walaupun tidak sekuat semen. Berdasarkan hal tersebut timbul suatu gagasan untuk mengganti dua material pembentuk beton yang masih sedikit penggunaannya sebagai bahan alam melimpah yang dijadikan material pembentuk beton. Penelitian ini bertujuan untuk mengetahui pengaruh gradasi campuran antara pasir laut dan pasir pozzolan, serta mengetahui pengaruh kuat tarik lentur beton mutu tinggi pada campuran pasir laut dan pozzolan, (sebanyak 25%, 50% dan 75%). Faktor Air Semen (FAS) yang digunakan 0,3, pengujian dilakukan pada umur 28 hari. Benda uji untuk kuat tarik lentur adalah balok berukuran 15 cm x 15 cm x 60 cm. Hasil penelitian ini menunjukkan bahwa beton menggunakan campuran CPZ 25% CPL 75% mempunyai kuat tarik lentur yang lebih tinggi dari campuran lainnya yaitu sebesar 3,55 MPa, hanya mengalami penurunan sebasar 0,65 MPa dari beton (0%) campuran. Dari hasil menunjukkan bahwa agregat yang digunakan sudah memenuhi syarat sebagai material pembentuk beton yang baik namun material tersebut dapat digunakan untuk campuran beton tanpa tulangan.

Kontrak merupakan kesepakatan antara pemilik proyek selaku pengguna jasa dengan penyedia jasa, baik dalam hal teknis, komersial, maupun dari segi hukum dengan poin-poin yang telah disepakati oleh pihak yang mengikat perjanjian. Salah satu kontrak yang sering digunakan adalah kontrak unit price dimana yang menjadi acuan adalah Bill of Quantity (BOQ) yang dikeluarkan oleh owner. Penelitian ini bertujuan mengindentifikasi yaitu faktor-faktor yang mempengaruhi kontrak unit price dan menganalisis aspek-aspek yang terkandung dalam jenis kontrak ini. Metode yang di gunakan dalam penelitian ini menggunakan data kualitatif dengan teknik sampling random. Kuisioner sebagai instrument penelitian dibagikan kepada 77 responden. Pengolahan data dilakukan dengan analisis validitas, reliabilitas, korelasi dan regresi linear berganda. Berdasarkan hasil penelitian diperoleh hasil uji validitas r hitung = 0,722 > r tabel = 0,1888, yang menujukkan setiap variabel sudah valid. Hasil uji reliabilitas sebesar 0,8 yaitu reliabel/handal karena nilai cronbach alpha > 0,6. Dari analisis korelasi diperoleh nilai R sebesar 0,695, maka nilai tersebut memiliki implikasi bahwa semua variabel berhubungan terhadap kontrak unit price dengan koefisien determinasi sebesar R2 = 48,4%. Model yang diperoleh dari analisis regresi linear berganda yaitu : Y= 7,319 – 0,102.X1 + 0,432.X2 + 0,299.X3 + 0,420.X4 - 0,516.X5 - 0,034.X6 - 0,820.X7 - 0,002.X8, dimana faktor dominannya adalah pada variabel X4 yaitu faktor waktu yang memiliki kontribusi sebesar 0,420, dikarenakan sering terjadi perubahan desain, perubahan schedule, banyaknya proyek yang ditangani dalam waktu yang sama, terlambatnya penyelesaian konstruksi akibat faktor eksternal dan kondisi lingkungan saat proyek akan dimulai.
