Effect of Job Stress on Job Satisfaction and Quality of Life of Beauty-Related Workers
Authors: Kim Ae-kyung
Published: December 2021

Purpose: This study investigated the effect of job stress on job satisfaction and quality of life of beauty-related workers.Methods: Data were collected from beautyrelated workers, and 358 surveys were analyzed using the SPSS WIN 21.0 program. Analysis methods included factor analysis, descriptive statistics, correlation analysis, linear regression analysis, and mediation regression analysis.Results: First, respondents were generally female, unmarried, 20–29 years old, had college or graduate school education, were hairdressers, and had a monthly average income of less than 2 million won. Second, the analysis of descriptive statistics and correlations between job stress, job satisfaction, and quality of life showed a statistically significant negative correlation with job satisfaction and quality of life for each sub-factor of job stress. Job satisfaction was found to have a statistically significant positive (+) correlation with quality of life. Third, job satisfaction partially mediated the relationship between job stress and quality of life as well as the relationship between role-related stress, home-related stress, and quality of life. The relationship between interpersonal stress, reward-related stress, and quality of life of job stress is full mediation.Conclusion: The efficient management of beauty-related workers’ job stress improves their job satisfaction and quality of life. Therefore, for managing each job’s stress factor, creating a manual appropriate to that type of beauty-related workplace will be helpful.

Published: December 2021

Purpose: This study was conducted to evaluate lavender, lemongrass, and peppermint grown in the Namwon-Mt.Jiri regions as functional soothing ingredients for cosmetics.Methods: The simultaneous analysis of 19 polyphenols in 50% ethanol-extracted samples of lavender, lemongrass, and peppermint cultivated in the Namwon-Mt.Jiri regions were analyzed by high-performance liquid chromatography (HPLC). Antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH). Using real-time PCR, improvements in skin barrier function were confirmed by observing the mRNA expression levels of filaggrin and involucrin, and the moisturizing ability was confirmed through the mRNA expression of HAS-2 and HAS-3. The anti-inflammatory efficacy was verified by confirming the expression levels of the inflammatory cytokine IL-6 and the pro-inflammatory mediator nitric oxide (NO).Results: In the simultaneous analysis of 19 phenolic compounds, rosmarinic acid from lavender; chlorogenic acid, syringic acid, p-coumaric acid, and ferulic acid from lemongrass; and caffeic acid, quercitin hydrate, rosmarinic acid, and hesperetin from peppermint were identified. Antioxidant efficacy was confirmed by DPPH radical scavenging, and excellent efficacy was shown in the order of lavender, peppermint, and lemongrass. Filaggrin and involucrin, skin barrier-related genes, were increased more in lavender, lemongrass, and peppermint than in the untreated group. HAS-2 and HAS-3 were also confirmed to be increased in lavender, lemongrass, and peppermint. Lavender, lemongrass, and peppermint all showed concentration-dependent inhibition of IL-6 and NO.Conclusion: Extracts of lavender, lemongrass, and peppermint cultivated in the Namwon-Mt.Jiri regions had excellent antioxidant, skin barrier, moisturizing and anti-inflammatory effects, so may be considered for use as natural raw materials for soothing cosmetics.

Published: December 2021

Purpose: This study was conducted to confirm the applicability of a mixed herbal extract (MHE) as an anti-aging cosmetic ingredient by investigating its skin anti-aging activities in vitro and in vivo.Methods: In this study, we prepared MHE using an ultrasonic extraction containing Forsythiae fructus, Tribuli fructus, Solomon’s seal, Siberian ginseng, Ponciri fructus and Ginseng. We investigated the anti-aging effect of the MHE for skin in dermal fibroblasts. The anti-aging activity was determined by the type I collagen synthesis levels. Matrix metalloproteinase-1 (MMP1) and tissue inhibitor of metalloproteinases 1 (TIMP1) mRNA levels were measured by qRT-PCR. MMP1 protein levels were evaluated by blotting analysis. Clinical tests of skin moisture, elasticity, texture, and wrinkles were performed using cosmetics containing 1% MHE.Results: The MHE induced the upregulation of pro-collagen type I synthesis and TIMP1 mRNA expression. The MHE led to the downregulation of MMP1 mRNA levels and protein levels. Furthermore, after skin application of cosmetics containing 1% MHE, skin hydration, elasticity, texture, and crow’s feet were improved 4 weeks after the treatment.Conclusion: MHE has an anti-aging effect by promoting collagen synthesis and suppressing MMP1 gene expression in vitro, and it has a skin improvement effect in vivo. Therefore, the MHE was shown to have value as a functional cosmetic ingredient.

Published: December 2021

AbstractThis study aims to investigate the effectiveness of macroprudential policies in mitigating the systemic risk in Indonesia. The study uses quantitative descriptive analysis with the Vector Error Correction Model (VECM) and emphasizes on the impact of two macroprudential instruments applied in Indonesia; Macroprudential Liquidity Buffer (MLB) and Countercyclical Capital Buffer (CCyB) to credit growth for conventional and financing growth for Sharia bank. This study employes monthly data over the periods M12010-M102019 that obtained from Bank Indonesia’s (BI) website (www.bi.go.di) and the data published monthly by Financial Service Authority (OJK); Indonesia Bank Statistic and Sharia Bank Statistic.The result indicates that MLB has a positive impact on credit growth and negative effect financing for Sharia Bank. Otherwise, CCyB shows the opposite results, where it has a negative effect on credit growth, while in the Sharia bank, CCyB has a positive effect. Therefore, it is sufficient to conclude that MLB has a capability to curb the systemic risk for Sharia bank, whereas CCyB is effective for conventional bank.

Метод демодуляции сигналов с пространственно-временным кодированием с применением нелинейного итерационного алгоритма
Authors: Крейнделин Виталий Борисович , Варукина Лидия Александровна
Published: December 2021

В условиях ограниченного частотного ресурса и при возрастающих требованиях к скорости передачи данных в системах радиосвязи возникает потребность в повышении их спектральной эффективности. Одной из технологий, многократно повышающей пропускную способность каналов (по сравнению с традиционными системами радиосвязи с одной передающей антенной), является технология пространственно-временного кодирования. Сдерживающим фактором развития систем с пространственно-временным кодированием является отсутствие эффективных алгоритмов обработки сигналов на приемной стороне, имеющих приемлемую вычислительную сложность. Предлагается новый алгоритм демодуляции сигналов с пространственно-временным кодированием, превосходящий по характеристикам помехоустойчивости известные алгоритмы и обладающий невысокой вычислительной сложностью.

Published: December 2021

Использование шумоподобных сигналов в радиолокации и радиосвязи вызывает необходимость анализа причин искажений этих сигналов в цепях усиления и преобразования вследствие того, что скорее искажения в цепях, а не структура сигнала, ограничивают дальнейшее улучшение характеристик обнаружения [1]. В качестве шумоподобного сигнала рассмотрим линейную рекуррентную последовательность максимального периода (М-последовательность), периодическая автокорреляционная функция (ПАКФ) которой близка к наилучшей.

Natalidade e revolução em Hannah Arendt
Authors: Batista Fernandes Antônio
Published: December 2021

O presente artigo tem por objetivo discutir o conceito de natalidade e sua relação com o fenômeno revolucionário a partir do pensamento de Hannah Arendt. Para tanto, laçaremos mão de algumas obras de referência da autora para pensar tal categoria, a saber: Origens do Totalitarismo (1951), A condição humana (1951) e Sobre a Revolução (1963). Para Arendt, o conceito de natalidade está diretamente relacionado a capacidade dos indivíduos de iniciarem coisas novas no mundo, isto é, de serem iniciadores de um mundo inteiramente novo. O fenômeno revolucionário moderno, por sua vez, representa um novus ardo saeclorum, uma novidade que se tornou possível por meio da ação conjunta dos homens e da capacidade de começar própria daqueles que são os recém-chegados ao mundo. Portanto, nosso problema consiste em constatar a centralidade do conceito de natalidade no pensamento político de Arendt, bem como sua relação com o fenômeno revolucionário moderno.
O Ele, os K.’s, o homem de boa vontade: Arendt, leitora de Kafka
Authors: Rocha Lara
Published: December 2021

O presente artigo analisa a leitura de Hannah Arendt sobre os textos de Franz Kafka, o que será feito a partir do prefácio de Entre o passado e o futuro, dos ensaios Franz Kafka: uma reavaliação e O judeu como pária: uma tradição oculta, além das narrativas kafkianas Descrição de uma luta, O Processo, O Castelo e da parábola Ele, identificando tanto o que as vincula como o definhamento do humano retratado pelo escritor. Porquanto o absurdo que reveste o cenário descrito por Kafka é percebido por Arendt como um presságio dos horrores praticados pelos regimes totalitários, nossa hipótese é que discutir a leitura da autora sobre os textos kafkianos auxilia a compreensão sobre as consequências desastrosas que as relações sociais podem acarretar e a desfiguração fomentada pela burocracia como aparelho organizacional e forma de governo que normaliza os procedimentos de rotina, os massacres administrativos, a obediência cadavérica e os processos infindáveis baseados em legislações superiores, utilizados como meios de gerir indivíduos desarraigados, indistinguíveis e massificados.
O Distanciamento entre filosofia e política, e o sentido da política em Hannah Arendt
Authors: Moreira Simão Tamíris
Published: December 2021

Hannah Arendt identifica no pensamento de Platão aquilo que ela designa como “Tirania da Verdade”, ao mesmo tempo em que nos mostra de que modo essa “tirania” se fundamenta a partir de uma cisão entre filosofia e política. Essa cisão causa uma progressiva degradação da política que deixa de ser o espaço do próprio exercício da liberdade para ser meramente aquilo que garante a existência de liberdades individuais e que preserva a reprodução da vida. Ademais, ao ser apartada da liberdade e da própria atividade do pensamento e do diálogo, a política se apropria do uso da força e a esfera política passa a ser a esfera da coerção. A política degradada, portanto, é aquela que perdeu o seu sentido, ou seja, que não proporciona espaço público para a discussão e compartilhamento de um mundo em comum. A degradação atinge seu ápice quando a pergunta “Qual é o sentido da política?” é suplantada por “Tem a política algum sentido?”. Em nosso artigo, buscamos mostrar o percurso argumentativo da filósofa que se inicia com o exame da “tirania da verdade” e da cisão entre filosofia e política até a consequente perda do próprio sentido da política. Para isso, examinaremos especialmente seus textos “Filosofia e Política”, “O que é autoridade?”, “Tradição e Idade Moderna” e “O sentido da Política”.
Adorno contra Nietzsche?
Authors: Barbosa Wesley
Published: December 2021

O presente artigo busca aproximar Adorno de Nietzsche, não como a exaltar ressentimentos e picuinhas, mas como a dialogar aspectos da crítica de ambos a uma cultura igualitária formadora de uma humanidade decaída e violenta, além de dócil e pouco crítica. Como leitor de Nietzsche, Adorno acertou ao indicar os processos de nivelamento social promovidas pelas sociedades econômicas contemporâneas. Assim como sua racionalização instrumental que culminou na barbárie(1939-1945). Exporemos uma crítica que busque diminuir os esteriótipos dos autores aproximando mais, o social, de Nietzsche, e o sujeito individual, de Adorno. No fim, tentaremos demonstrar como o conceito de solidariedade em Adorno não resolve melhor a questão ética, que a avaliação como valor para a construção de valores, sendo a proposição imoralista de Nietzsche, muito mais um recurso provocativo, que uma assertiva de caráter fundamental.

Published: December 2021

The ecosystem restoration conservation partnership program is a new policy from the Ministry of Environment and Forestry which aims to reduce conflicts due to forest land use in conservation areas. Gunung Halimun Salak National Park (GHSNP) is one of the conservation areas facing tenure conflicts, particularly in the Gunung Botol Resort area, where there are people who have lived and cultivated the land for decades, long before the Decree of the Designation of the GHSNP was issued. In an effort to address tenurial conflicts in Malasari Village, which is one of the villages within the management area of Gunung Botol Resort, the community took the initiative to collaborate with the GHSNP manager through a scheme called ecosystem restoration conservation partnership. This study aims to formulate a strategy for developing an ecosystem restoration conservation partnership in GHSNP by using a qualitative approach which is presented in a descriptive form. Data were analyzed using SWOT (Strengths, Weaknesses, Opportunities, and Threats) technique. The results of the study indicate that the ecosystem restoration conservation partnership program is recommended to be implemented by utilizing existing strengths and opportunities, as well as developed through synergy and collaboration that involves multi-stakeholders.

Published: December 2021

Ecological politics rely solely on economic interest. Development and the environment have a complicated correlation. The industrial plantation forest policy aims to ensure that the economic benefit goes hand in hand with the sustainability demand. Ironically, this policy triggers a conflict between local communities and corporations as the holder of forest concession rights. The concession is practically established due to merely economic interest aligned with the extractive industry of tobacco in Lombok. The plantation is aimed as the supporting source for the tobacco industry since it requires specific woods to roast the tobacco. The study refers to utilizes instrumental state theory and deep ecology perspective to identify how the policy was made for the capital and tobacco capital benefits, while the sustainability objective is left behind. The study shows not only how the concession sparked ironic economic development, but also how the liberal environmentalism approach in industrial forest plantation policy has failed to gain its objective. The economic potential of tobacco in Lombok is the main determinant in industrial forest plantation policy that changes community forests into private forests. In the end, the policy was strategically implemented to sustain production and strengthen corporation monopoly over forests.

The purpose of this study is to evaluate the texting, sharing, and mentoring (TSM) method as an innovative method of community empowerment applied in 'Go-Honey' program. This method is mixed offline and online with the use of Whatsapp groups connecting program participants, resource persons, and local mentors. Using the Bloom's Taxonomy approach, this study compares the knowledge level of the 'Go-Honey' program participants implementing TSM with other sitngless beekeeping program participants who use the single-face-to-face (TTM) method as a control. The total participants involved in this study were 20 people, half of whom were female members of 'Go-honey', while the other half were not. Participants were asked questions related to cognitive, affective and psychomotor aspects by direct interviews. Observations were also done on the results of the work performance. The results show that the 'Go-Honey' participants have a higher level of knowledge about stingless beekeeping compared to the control model in these three aspects of knowledge. The results of the Mann Whitney test shows that the cognitive, affective and psychomotor scores are significantly different at 1 % alpha. This method has the potential to be applied after the pandemic ends with the principle of distance learning as long as there is the internet connection and the presence of local mentors.

Gravitational Fields and Gravitational Waves
Authors: Yuan Tony
Published: December 2021

The relative velocity between objects with ﬁnite velocity aﬀects the reaction between them. This eﬀect is known as general Doppler eﬀect. The Laser Interferometer Gravitational-Wave Observatory (LIGO) discovered gravitational waves and found their speed to be equal to the speed of light c. Gravitational waves are generated following a disturbance in the gravitational ﬁeld; they aﬀect the gravitational force on an object. Just as light waves are subject to the Doppler eﬀect, so are gravitational waves. This article explores the following research questions concerning gravitational waves: What is the spatial distribution of gravitational waves? Can the speed of a gravitational wave represent the speed of the gravitational ﬁeld (the speed of the action of the gravitational ﬁeld upon the object)? What is the speed of the gravitational ﬁeld? Do gravitational waves caused by the revolution of the Sun aﬀect planetary precession? Can we modify Newton’s gravitational equation through the inﬂuence of gravitational waves?

Published: December 2021

The rapid industrial growth in solar energy is gaining increasing interest in renewable power from smart grids and plants. Anomaly detection in photovoltaic (PV) systems is a demanding task. In this sense, it is vital to utilize recent advances in machine learning to accurately and timely detect different anomalies and condition monitoring. This paper addresses this issue by evaluating different machine learning techniques and schemes and showing how to apply these approaches to solve anomaly detection and detect faults on photovoltaic components. For this, we apply distinct state-of-the-art machine learning techniques (AutoEncoder Long Short-Term Memory (AE-LSTM), Facebook-Prophet, and Isolation Forest) to detect faults/anomalies and evaluate their performance. These models shall identify the PV system's healthy and abnormal actual behaviors. Our results provide clear insights to make an informed decision, especially with experimental trade-offs for such complex solution space.

Published: December 2021

Although the relations between sleep and academic performance have been extensively examined, how sleep predicts future academic performance (e.g., 2 -3 years) remains to be further investigated. Using wearable smartwatches and a self-report questionnaire, we tracked sleep activities of 45 college students over a period of approximate half a month to see whether their sleep activities predicted their academic performance, which was estimated by grade point average (GPA). Results showed that both nighttime sleep awakening frequency and its consistency in the tracking period were not significantly correlated with the GPA for the courses taken in the semester during sleep tracking (current GPA). However, both nighttime sleep awakening frequency and its consistency inversely predicted the GPA for the rest of the courses taken after that semester (future GPA). Moreover, students with more difficulty staying awake throughout the day obtained lower current and future GPAs, and students with lower inconsistency of sleep quality obtained lower future GPA. Together, these findings highlight the importance of nighttime sleep awakening frequency and consistency in predicting future academic performance and emphasize the necessity of assessing the consistency of sleep measures in future studies.

Published: December 2021

This research work deals with traffic accidents that are very concurrent in several countries, which in turn contribute to the mortality rate from 19 to 25 years of age and up. In the research work, immediate notifications for traffic accidents were carried out through a mobile application (app) where it will have an emergency button which will help the injured a lot, since the nearest help centers such as the police, fire brigades and the nearest hospitals, so that they can provide support to the people who suffered the accident. In the project, the implementation of Scrum Methodology was used since it served us an amount for the development of the prototypes of the App, and in turn with their roles it did not serve much help for the project, however, passers-by are of vital importance already that they will be the ones to make said report when observing a traffic accident and thus notify the nearest aid centers.

Glaucoma is a leading cause of blindness. Surgical and pharmacological treatment of glaucoma aims to lower the intraocular pressure (IOP) and preserve visual function. The severe acute res-piratory syndrome coronavirus 2 pandemic has placed a strain on the healthcare system. We aimed to compare the quantity, type of anti-glaucoma surgeries, and the disease stage before and during the coronavirus disease pandemic. We analyzed 362 eyes of 306 patients and 172 eyes of 149 patients from the pre-pandemic and pandemic groups, respectively. The number of an-ti-glaucoma surgeries was halved during the pandemic compared to a similar pre-pandemic pe-riod, with a significant difference in the procedural structures between the two groups (p<0.001). The most common procedures in the pre-pandemic group were Ex-Press implantation (33.7%) and trabeculectomy (31.5%). Within the pandemic group, half of the eyes underwent tra-beculectomy (50.0%), followed by Preserflo microshunt (11.6%). A significant difference in the average IOPs was revealed among patients who qualified for surgery 22.21 ± 7.83 mmHg in the pre-pandemic group and 25.16 ± 9.48 mmHg in the pandemic group; p<0.001). There was no significant difference in the best corrected visual acuity between the groups (p=0.263). Glaucoma treatment remained relatively accessible during the pandemic.
Thinning as Method to Regulate Sweet Cherry Crops – a Review
Authors: Rutkowski Krzysztof , Łysiak Grzegorz P
Published: December 2021

In perennial fruit crops, bearing can be influenced by various factors, including environmental conditions, germplasm, rootstocks, and cultivation methods. Cherries, one of the most important and popular fruit species from the temperate climate zone, achieve high prices on the market. New agricultural technologies and environmental factors force a change in the approach to cherry cultivation. Old-type cherry orchards with their high demand for water, nutrients and manual work are replaced by orchards of self-pollinating cherry cultivars grown on dwarf rootstocks. These changes make it necessary to search for ways to regulate fruiting, in particular to thin buds, flower and fruit. In view of environmental regulations and consumer pressure, thinning methods are being sought that either do not involve the use of chemicals or that use eco-friendly chemical agents. This review examines recent progress in understanding the effect of thinning methods on the physiology, tree growth and fruit quality of cherries, discusses horticultural practices aimed to ensure regular cropping and their influence on fruit quality, and provides suggestions for future research.
The Impact of the "Belt and Road" Initiative on Tourism Economic Development in Chinese Regions Along the Route---An Empirical Analysis Based on DID Model
Authors: Lu Yuyang , Colak Alaaddin
Published: December 2021

As an important component of modern service industry, tourism is regarded as a "green" driver to regional economic growth and industrial upgrading. Applying the "quasi-natural experiment" advocated by the “The Belt and Road” Initiative, this paper, based on the method of DID, as-sessed the influence of this initiative on regional tourism development by analyzing panel data collected from 286 prefecture-level cities in China over the period of 2007-2018. It is found that the "The Belt and Road" initiative has stimulated market dynamics and promoted tourism de-velopment in the regions along the route, and has significantly improved indicators such as per capita domestic and inbound tourism revenue and per capita domestic and inbound tourist re-ceipt. Also, the degree of contribution of domestic tourists to the tourism economy of the re-gions where the policy has been implemented is stronger than that of inbound tourists. In sum, the results of this paper not only confirm that the “The Belt and Road” Initiative has significantly contributed to the high-quality tourism development of Chinese provinces along the routes, but also provide important policy enlightenment for the upgrading of regional tourism industry and regional economic balance.
Spider Toxin SNX-482 Gating Modifier Spontaneously Partitions in the Membrane Guided by Electrostatic Interactions
Authors: Mellado Guido , Garate Jose Antonio , Neely Alan
Published: December 2021

Spider toxin SNX-482 is a cysteine-rich peptide that interferes with calcium channel activity by binding to voltage-sensing domains of CaV2.3 subtype. Two general binding mechanisms are present in nature: direct binding from the aqueous phase or through lateral diffusion from the membrane, the so-called reduction in dimensionality mechanism. In this work, via coarse-grained and atomistic molecular dynamics simulations, we have systematically studied the spontaneous partitioning of SNX-482 with membranes of different anionic compositions and explored via diffusional analysis both binding mechanisms. Our simulations revealed a conserved protein patch that inserts within the membrane, a preference for binding towards partially negatively charged membranes, and that electrostatics drives membrane binding. Finally, diffusivity calculations showed that the toxin diffusion along the membrane plane is an order of magnitude slower than the aqueous phase suggesting that the critical factor in determin-ing the SNX-482-CaV2.3 binding mechanism is the affinity between the membrane and SNX-482

Published: December 2021

Attracting and retaining international students has been widely discussed in higher education settings. Increasing the number of international students has become an indispensable strategy for national and global competition. This study focuses on effective strategies and international students' issues regarding satisfaction in the most popular STEM (science, technology, engineering, and mathematics) programs. We designed a structural equation modeling (SEM) method to determine the effect of institutional mediation between push factors and satisfaction factors for the development of better strategies by which to attract and retain international students. Taking Taiwan as an example, this study employed a self-designed questionnaire to collect data: 485 degree-seeking international students in STEM programs were invited and successfully participated in this study during spring 2021. IBM SPSS 26 and AMOS 26 (Analysis of Moment Structure) were used to carry out the data analysis. We employed reliability, factor, and SEM analyses. This study assumed that the impact of push factors can be modified by institutional situations and result in international students’ satisfaction with their learning and environment and regarding migration policy. The results revealed that the predictors, mediation, and criteria were significant at the 0.05 or 0.01 levels. The findings suggest that push factors impact international students’ satisfaction when using institutional leadership and international strategy. The results of the bootstrap with a generalized least square method showed that the SEM model fit in 2000 bootstrap samples. The effect of institutional mediation can provide useful information for STEM programs to boost their future recruitment and retention strategies. This study provides an innovative approach to the detection of issues among international students in specific programs. These findings can enrich our knowledge regarding attracting and retaining global students in higher education settings.

Published: December 2021

Immunoglobulin G (IgG) adopts a modular multidomain structure that mediates antigen recognition and effector functions, such as complement-dependent cytotoxicity. IgG molecules are self-assembled into a hexameric ring on antigen-containing membranes, recruiting the complement component, C1q. To provide deeper insights into the initial step of the complement pathway, we report a high-speed atomic force microscopy study for quantitative visualization of the interaction between IgG and the C1 complex composed of C1q, C1r, and C1s. Results showed that C1q in the C1 complex is restricted regarding internal motion and has a stronger binding affinity for on-membrane IgG assemblages than C1q alone, presumably because of smaller conformational entropy loss upon binding. Furthermore, we visualized a 1:1 stoichiometric interaction between C1/C1q and an IgG variant that lacks the entire CH1 domain in the absence of antigen. In addition to the canonical C1q-binding site on Fc, their interactions are mediated through a secondary site on the CL domain that is cryptic in the presence of the CH1 domain. Our findings offer clues for novel-modality therapeutic antibodies.

There are multiple factors determined causing the land subsidence (e.g. man-made and natural-climate change) which have impact on the urban built environment economic spectrum e.g. buildings, properties, infrastructures and land. This paper presents the cause-effect investigation of the causing factors which influence the direct-indirect impacting urban economic factor via multi-regression analysis using Shanghai megacity as case study. Factors are selected based on existing UUS-subsidence-economic impact (USEM) framework as well as modification and adaptation from Shanghai Masterplan 2017-2035 (SM 2035) and Sustainable Development Goals (SDGs) 2030. Data are gathered secondarily via open sources e.g. scientific journal articles and reports. The results are parallel to previous studies on the current trend for rapid and unconscious UUS exploration development including tunneling seepage and leakage as leading causes for further land subsidence in Shanghai. A further concrete multi-integrated macro-scale USEM’s awareness and knowledge is needed to avoid future costlier damage. The highly regressed causing factors include increasing population, UUS-induced subsidence, underground tunnel leakage, cumulative UUS development and subsidence whereas building prices, reconstruction area ratio, land price, green buildings, tunnel settlement, loss of arable land, number of death and government revenue are the among the most impacted. Officials in Shanghai may further consider results for future USEM masterplans to prevent further unsustainability. It is also found that developing megacity may possess different factors according to their distinct condition.

The condition of unfertile paddy field due to excessive inorganic fertilizer application causing soil degradation. Fertilizing techniques using phosphate solubilizing  and nitrogen fixer bacteria are breakthroughs that should be developed in paddy cultivation to increase fertility soil and harvest of rice. This research aims to study on phosphate solubilizing and nitrogen fixer bacteria ability to increase the harvest of rice by increasing chemical and biological fertility of soil. The research was conducted in the greenhouse of Sawah Baru experimental garden, IPB University. The design used was a completely randomized design with one factor that was dosage of inorganic fertilizers (NPK) with seven levels that were control, NPK 100%, NPK 0% + bacteria, NPK 25% + bacteria, NPK 50% + bacteria, NPK 75% + bacteria and NPK 100% + bacteria. Each stage was repeated four times, so there were 28 units. The results of  phosphate solubilizing and nitrogen fixer bacteria could produce more rice grain 0.32 ton.ha-1 than NPK 100% (recommended dose). Biological soil fertility improved with the increased population of bacteria, but there was no improved soil chemical fertility of soil.
