Tinjauan Hukum Islam Terhadap Praktik Poligami dalam Masyarakat (Studi Pada Pasangan Poligami Di Kecamatan Umbulharjo Kota Yogyakarta)
Authors: Duri Rofika
Published: October 2023

Islam adalah agama yang memberikan pedoman hidup sangat lengkap kepada manusia, termasuk pedoman hidup berumah tangga. Pedoman berumah tangga yang sudah ada dalam Islam dapat membangun keluarga yang sakinah mawaddah warahmah. Namun faktanya, salah satu pemicu terjadinya konflik dalam rumah tangga sehingga berdampak pada sulitnya mewujudkan keluarga sakinah adalah poligami yang tidak sehat. Al-Qur’an memang membolehkan poligami, kebolehan poligami ini dengan menekankan syarat amat tinggi yaitu mampu berlaku adil. Tulisan ini membahas tentang praktik poligami dengan pendekatan normatif. Disini penyusun ingin mengetahui bagaimana praktik poligami yang terjadi pada dua pasangan di Kecamatan Umbulharjo Kota Yogyakarta dan bagaimana tinjauan hukum Islam terhadap dua pelaku praktik poligami tesebut. Artikel ini berpendapat bahwa dalam hal proses melakukan praktik poligami kedua keluarga di Kecamatan Umbulharjo sudah sesuai dengan UU No.1 Tahun 1974 Tentang Perkawinan. Namun, tidak direalisasikan sesuai dengan QS. An-Nisa’ (4): 3 yang menekankan harus mampu berlaku adil. Pasangan praktik poligami ini tidak dapat dikategorikan sebagai keluarga yang sakinah karena tidak ada ketenangan dan ketentraman jiwa dalam rumah tangga yang menjadi tujuan dari perkawinan

Published: October 2023

Perkawinan adalah ikatan lahir batin antara laki-laki dan perempuan sebagai suami istri dengan tujuan membentuk keluarga (rumah tangga) yang bahagia. Perkawina di Indonesia sering dilaksanakan dengan berpodam pada hukum adat yang ada pada masing-masing daerah. Penelitian ini menggunakan jenis penelitian kepustakaan library research, sebagai sumber utamanya adalah buku dan artikel yang berkaitan. Tujuan artikel ini untuk mengetahui kontribusi hukum adat dalam membangun keharmonisan keluarga. Tidak bisa dipungkiri bahwasanya adat seringkali mengintervensi sesorang untuk melakukan perkawian. Pengaplikasian adata dalam hukum Islam, mendapatkan justifikasi dari Syariat, terbukti dengan banyaknya hukum-hukum pada masa jahilyah yang diberlakukan kembali pada masa Islam. dan keberlakuan adat semakin kuat dengan adanya argumentasi baik yang bersumber dari al-Qur’an, Hadis Nabi, maupun dari praktek yang dilakukan oleh para ulama. Di lingkungan masyarakat untuk melakukan perkawinan tidak lepas dari pengaruh kebudayaan sehingga sering dikaitkan perlaksaan perkawinan tersebut pada usia yang sudah dapat melakukan perkawinan. Pengaruh kebudayaaan pada pelaksanaan perkawinan dalam masyarakat sangat penting bagi keluarga untuk membangun keharmonisan.

Published: October 2023

The article provides insights into the drivers of spatial re-localisation within the production networks of the solar photovoltaic (PV) industry. In doing so, we combine the perspectives of Global Value Chain (GVC), Global Production Network (GPN) and institutional path creation perspective to analyse the relocation and upgrading of multinational corporations (MNCs) in Malaysia using interviews and trade data. Our findings show that institutional path creation has helped to promote the completeness of the entire solar PV value chain in Malaysia, with the state actively intervening and creating new pathways by learning from the experience of the electronics industry, especially in the pre-foundation phase. Nevertheless, the path creation is also limited in that they have only been able to open windows of investment and trade opportunities within the different segments of the GVC without doing much to promote technological learning and spillover effects as the governance structure of the value chain is integrated. We find that other factors are less helpful in promoting local spillovers – exportoriented policies, energy policies and domestic industry dynamics due to lack of policy coordination. The results draw attention to some important issues that deserve closer consideration and contribute to the theoretical discussion within the GVC and GPN literature. First, path creation occurs at both levels - at the level of institutions and at the level of firms’ strategic decisions. Second, institutional path creation acts as exogenous shocks to firm path creation leading to different strategic choices, and the two reinforce each other. In other words, we have shown the complexity of path creation in the context of GVC and GPN. Third, institutional path creation is subject to dynamic coordination among agencies, without which path formation is constrained.
Upgrading within Global Value Chains and Innovation Capabilities: Lessons from Indian Information Technology Sector
Authors: Mehta Swati , Baskaran Angathevar
Published: October 2023

This study examines the process, nature, and drivers of upgrading among Indian information technology (IT) services firms in the global value chain (GVC) by analysing the sector as a whole and examining three cases – Tata Consultancy Services (TCS), Infosys and Wipro. It uses a qualitative research approach and data obtained from secondary sources such as the Organization for Economic Co-operation and Development (OECD) Trade in Value Added (TiVA) online database, company websites and annual reports. The study found that the contribution of India’s IT sector to GVC is relatively high among service sectors. It is increasingly delivering high-value products, reflecting its upgrading within the GVC. Indian IT firms have gradually transformed from being subcontractors providing low-value-added products and services to providing complete projects and solutions. The three cases show that upgrading of India’s IT firms was mainly due to continuous efforts to build innovation capacity by forging partnerships with other technology leaders, start-ups, and academic institutions, and through acquisitions. India needs to design specific industrial policy with enabling institutions to increase domestic value-added (DVA) and develop a foreign direct investment (FDI) policy that focuses on attracting multinational corporations (MNCs) with GVC linkages.

Authors: Cha Yoon-ho , Kim Jung Heon , Chung Seung Ah
Published: October 2023

Purpose: This study was performed to examine a comprehensive profile of ophthalmic (OPH) referrals based on diagnosis in a single emergency department (ED) in Korea.Methods: We analyzed the clinical profiles of children (< 18 years) who underwent immediate OPH referrals in a tertiary hospital ED, from March 2013 through December 2022. Exclusion criteria were a visit related to procedural complication and a discharge before thorough evaluation. We focused on a diagnosis-based high OPH severity requiring emergency surgery or hospitalization. The profiles were compared according to the severity and age group (0-3, 4-6, 7-12, and 13-17 years).Results: A total of 1,939 children consisted of 1,281 (66.1%) with injury and 658 (33.9%) with non-injury. Top 3 injuries were orbital fracture, hyphema, and corneal abrasion, whereas top 3 non-injuries were keratoconjunctivitis, cellulitis, and hordeolum. Children with high OPH severity (54.5%) had significantly lower proportions of girls (26.5% vs. 38.9%), visits on weekend/holiday (34.4% vs. 43.4%), and most non-injury chief complaints, and higher proportions of 13-17 years (41.1% vs. 23.6%), injury (87.7% vs. 40.1%), emergency surgery (4.9% vs. 0.1%), in-ED procedure (9.3% vs. 2.4%), hospitalization (4.0% vs. 0.8%), and most injury mechanisms. With increasing age, high OPH severity, orbital fracture, and hyphema increased in proportions, in contrast to a decreasing tendency in corneal abrasion, keratoconjunctivitis, cellulitis, and hordeolum (all Ps for trend ≤ 0.001). There were 610 (31.5%) children with low OPH severity or no OPH diagnosis.Conclusion: True OPH emergencies may be more common in injured, older, or male children. This finding could be useful in focusing on emergencies while diverting less urgent cases to outpatient departments or outside ophthalmology clinics.

Published: October 2023

The port’s adoption of environmental criteria and the incorporation of sustainable activities involves numerous challenging issues, such as limiting emissions caused by current and upcoming port operations. One of the three dimensions of sustainability that have been specified by Souza and Alves (2018) is environmental sustainability. On the other hand, the public authorities and the wider community have put strong pressure on ports to fulfil their social responsibility (De Grosbois, 2016). The current study aims to promote the linkage of the largest European port’s efficiency with environmental regulations and the International Convention for the Prevention of Pollution from Ships (MARPOL). Previous studies have examined the effect of basic individual environmental factors on the port’s effectiveness. The innovation of the study focuses on the relation of MARPOL regulations to the port’s efficiency as well as several environmental guidelines and sustainable development goals after the pandemic. It is the first study that incorporates efficiency variables with climatology programs, safe and healthy environmental variables, global reporting initiatives, and MARPOL Annexes. The basis of the data is the top twenty ports obtained from Eurostat and processed using multiple regression analysis.

Published: October 2023

Refocusing strategy has become one of the fiscal policies adopted by the government when the COVID-19 pandemic hit Indonesia. This strategy involves reallocating the budget from personnel, goods, and capital expenditures to fund the National Economic Recovery Program. However, the implementation of this policy, without adequate preparation, can have performance implications. This research addresses the challenges related to the dynamic and adaptive state budget during a crisis. The method used is a case study based on facts, which is then analyzed using the theory of Budgeting Flexibility, considering three inseparable aspects in achieving budget flexibility: agreement on purposes, mutual commitment between parties, and creating agile organizations. Therefore, Refocusing does not compromise the performance of executing tasks and functions in supporting the implementation of programs aimed at improving the professionalism of teachers in Madrasah education. This research will serve as the basis for policymakers in budget implementation across all levels in the Ministry of Religious Affairs Regional Office for DKI Jakarta Province.

Published: October 2023

In 2019, the Louisiana Department of Health reported an early influenza
B/Victoria (B/VIC) virus outbreak. As it was an atypically large
outbreak, we deployed to Louisiana to investigate it using genomics and
a triplex real-time RT-PCR assay to detect three antigenically distinct
B/VIC lineage variant viruses. The investigation indicated that B/VIC
V1A.3 subclade, containing a three amino acid deletion in the
hemagglutinin and known to be antigenically distinct to the
B/Colorado/06/2017 vaccine virus, was the most prevalent circulating
virus within the specimens tested. This work underscores the value of
portable diagnostics and sequencing platforms for rapid, onsite pathogen
characterization.

Papillary fibroelastoma is the rarest of the primary benign cardiac
tumors, with the one located in the pulmonary valve being the rarest,
even after the one that affects the ventricular endocardium. In the
past, this type of tumor was generally a fortuitous finding in surgery
or necropsy and with the great availability of transthoracic
echocardiography, it is now more likely that they can be diagnosed.

A six-week-old male Shetland pony is presented with pollakiuria and a
scrotal mass. The diagnostic procedures conducted included a thorough
clinical examination, external palpation, a scrotal ultrasonographic
exam and urinary catheterization. These revealed an indirect herniation
of the urinary bladder into the tunica vaginalis. Subsequently, the case
was managed surgically by performing a partial cystectomy through an
inguinal approach. Bilateral castration was performed with the affected
side an additional closure of the superficial inguinal ring. Five months
post-surgery, a routine telephone questionnaire highlighted no
post-operative concerns. Gross examination of the inguinal region
revealed no abnormalities and the foal was maturing as expected.
Feeding habits and preferences of southern gelada (Theropithecus gelada obscurus, Heuglin 1863) in Abune Yosef Zigit Community Conservation Area, northern Ethiopia
Authors: Ewnetu Setie , Girma Zerihun
Published: October 2023

The feeding habits and preferences of gelada has been studied in
different parts of Ethiopia. However, still the diet composition and
preferences of the species is poorly understood because of diet
composition and preference variations among its ranges. Therefore, this
study is aimed at investigating the diet composition and preferences of
southern gelada in remote unexplored Abune Yosef Zigit Community
Conservation Area. Diet composition was assessed by instantaneous scan
sampling within a 10-minute interval lasting for 5-minutes and feeding
preferences by systematic random sampling. The data was collected for
two seasons: the dry season (February 2021 to April 2021) and the wet
season (June 2021 to August 2021). Sorenson’s similarity index was used
to compute diet similarity during both seasons. The result revealed that
a mean total of 22 plants, 3 insect species and unidentified tubers were
consumed by southern gelada. An average of 55.11% forbs, 41.71%
graminoids, 1.61% insects and 1.59% unidentified tubers were consumed
by southern gelada. The top two preferred fodder species were Festuca
richardii (12.55%) and Rumex nepalensis (10.80%). Southern gelada
feeding preference is significantly influenced by plant availability and
utilization frequency (P≤0.05). Festuca rechardii is the most desired
diet for gelada, and plantation should be supported to increase its
availability.
Dementia and Depression: Biological Connections with Amyloid β Protein

Published: October 2023

Dementia is an umbrella term for a broad group of age-associated
neurodegenerative diseases. It is estimated that dementia affects 50
million people worldwide and that Alzheimer’s disease (AD) is
responsible for up to 75% of cases. Small extracellular senile plaques
composed of filamentous aggregates of amyloid β (Aβ) protein tend to
bind to neuronal receptors, affecting cholinergic, serotonergic,
dopaminergic, and noradrenergic neurotransmission, leading to
neuroinflammation, among other pathophysiologic processes, and
subsequent neuronal death, followed by dementia. The amyloid cascade
hypothesis points to a pathological process in the cleavage of the
amyloid precursor protein (APP), resulting in pathological Aβ. There is
a close relationship between the pathologies that lead to dementia and
depression. It is estimated that depression is prevalent in up to 90%
of individuals diagnosed with Parkinson’s disease, with varying
severity, and in 20 to 30% of cases of Alzheimer’s disease. The
hypothalamic pituitary adrenal (HPA) axis is the great intermediary
between the pathophysiological mechanisms in neurodegenerative diseases
and depression. This review discusses the role of Aβ protein in the
pathophysiological mechanisms of dementia and depression, considering
the HPA axis, neuroinflammation, oxidative stress, signaling pathways,
and neurotransmission.
Choice overload interferes early processing and necessitates late compensation: evidence from electroencephalogram
Authors: Hu Xinye , Meng Zong , He Qinghua
Published: October 2023

Having a multitude of choices can be advantageous, yet an abundance of
options can be detrimental to the decision-making process. Based on
existing research, the present study combined electroencephalogram and
self-reported methodologies to investigate the neural mechanisms
underlying the phenomenon of choice overload. Behavioral data suggested
that an increase in the number of options led to negative evaluations
and avoidance of choice tendencies, even in the absence of time
pressure. Event-related potential results indicated that the large
choice set interfered with the early visual process, as evidenced by the
small P1 amplitude, and failed to attract more attentional resources in
the early stage, as evidenced by the small amplitude of P2 and N2.
However, the LPC amplitude was increased in the late stage, suggesting
greater investment of attentional resources and higher emotional
arousal. Multivariate pattern analysis revealed that the difference
between small and large choice set began at around 120ms and the early
and late stages were characterized by opposite activation patterns. In
conclusion, this study suggested that too many options interfered with
early processing and necessitate continued processing at a later stage.
Temporal Dynamics of Autonomic Nervous System Responses under Cognitive-Emotional Workload in Obsessive-Compulsive Disorder
Authors: Portnova Galina , Khayrullina Guzal , Martynova Olga
Published: October 2023

Dysregulation of the autonomic nervous system (ANS) is commonly observed
in different mental disorders, especially when individuals engage in
prolonged cognitive-emotional tasks that necessitate an adjustment of
the ANS to workload. Although understanding of the temporal dynamics of
sympathetic and parasympathetic tones in obsessive compulsive disorder
(OCD) is limited, analyzing the ANS reactions on cognitive-emotional
workload could provide a valuable insight into the underlying causes of
OCD. This study investigated the temporal dynamics of the heart rate
(HR) and pupil area (PA) while participants with OCD and healthy
volunteers solved antisaccade tasks where affective pictures served as
central fixation stimuli. The data of 31 individuals with OCD and 30
healthy volunteers were included in the study. The experiment consisted
of three separate blocks, each lasting approximately 8 minutes. The
results showed the increase in sympathetic tone in the OCD group. The
increase in sympathetic tone of the ANS in OCD at the middle part of the
block was most noticeable during presentation of unpleasant stimuli. The
healthy volunteers demonstrated adaptive temporal dynamics of the HR and
PA from the first block to the last block of tasks, while HR and PA in
the OCD group showed less changes in time implying the reduced
adaptation of the ANS sympathetic tone to cognitive-emotional workload
in OCD.

Objective: To confirm the differences in the risk factors for epithelial
ovarian cancer-associated venous thromboembolism (EOC-VTE) among
patients on different continents. Methods: We reviewed all EOC-VTE cases
from two tertiary hospitals for ten years. Multivariate logistic
regression analysis was used to identify significant risk factors for
VTE. Then we searched the literature on EOC-VTE risk assessments. The
risk factors presented in the acquired literature and our data were
evaluated by meta-analysis. Two subgroups, according to the continents
mentioned in the studies, were set as Asia and Europe & America,
respectively for analyzation. Results: A total of 122 patients with
EOC-VTE were included. We found six significant risk factors for VTE
among cases of EOC by multivariate logistic regression analysis. Among
the 2064 initial articles, only 30 met the inclusion criteria. Including
our data, there were cumulative 1432 cases and 9874 controls. The
meta-analysis selected 13 out of 23 possible risk factors. Risk factors
were not identical between subgroups. Except for five same elements, the
Asia subgroup had six other significant risk factors for EOC-VTE that
were preoperative D-Dimer > 0.3mg/L (OR: 5.030, 95% CI:
2.003-12.635), surgery time ≥ 180min (OR: 3.459, 95% CI: 2.198-5.441),
WHO performance status score > 1 (OR: 2.847, 95% CI:
1.840-4.405), hypertension (OR: 1.945, 95% CI: 1.238-3.058), age ≥ 60
years (OR: 1.821, 95% CI: 1.374-2.413) and preoperative blood platelet
> 300 × 109/L (OR: 1.532, 95% CI: 1.025-2.289).
Accordingly, another two significant risk factors were found in Europe
& America subgroup, which were the initial FIGO stage (Ⅲ/Ⅳ) (OR: 2.837,
95% CI: 2.147-3.748) and postmenopausal status (OR: 1.926, 95% CI:
1.025-3.622). Six EOC-VTE risk factors in our data were covered by the
11 risk factors of Asian subgroup analyzes. Conclusions: Patients in
Asia and Europe & America have different risk factors for EOC-VTE.
Incorporation of Sub-Resolution Porosity into Two-Phase Flow Models with a Multiscale Pore Network
Authors: FOROUGHI SAJJAD , Bijeljic Branko , Gao Ying , Blunt Martin Julian
Published: October 2023

Porous materials, such as carbonate rocks, frequently have pore sizes
which span many orders of magnitude. This is a challenge for models that
rely on an image of the pore space, since much of the pore space may be
unresolved. There is a trade off between image size and resolution. For
most carbonates, to have an image sufficiently large to be
representative of the pore structure, many fine details cannot be
captured. In this work, sub-resolution porosity in X-ray images is
characterized using differential imaging which quantifies the difference
between a dry scan and 30 wt\% KI brine saturated rock
images. Once characterized, we develop a robust workflow to incorporate
the sub-resolution pore space into network model using Darcy-type
elements called micro-links. Each grain voxel with sub-resolution
porosity is assigned to the two nearest resolved pores using an
automatic dilation algorithm. By including these micro-links with
empirical models in flow modeling, we simulate single-phase and
multiphase flow. By fine-tuning the micro-link empirical models, we
achieve effective permeability, formation factor, and drainage capillary
pressure predictions that align with experimental results. We then show
that our model can successfully predict steady-state relative
permeability measurements on a water-wet Estaillades carbonate sample
within the uncertainty of the experiments and modeling. Our approach of
incorporating sub-resolution porosity in two-phase flow modeling using
image-based multiscale pore network techniques can capture complex pore
structures and accurately predict flow behavior in porous materials with
a wide range of pore size.

desenvolvem a partir de um núcleo o qual pode ser um fragmento de rocha, restos de
origem biogênica como dentes de tubarão ou carapaças de organismos como os radiolários e
até mesmo fragmentos de antigos nódulos. Em sua composição química, os nódulos
polimetálicos possuem metais estratégicos como níquel, cobalto e cobre, bem como a
presença de terras raras, metais amplamente utilizados hoje em dia para o
desenvolvimento tecnológico e econômico dos países industrializados. No presente estudo
demonstra-se do desenvolvimento desde nódulos e o valor estratégico e econômico de sua
exploração. Estes depósitos apresentam um valor econômico de importância mundial devido
aos inúmeros elementos químicos que formam sua composição. Palavras-chave: nódulos
polimetálicos, ocorrência de nódulos, formação de nódulos. Abstract The distribution of
polymetallic nodules and crusts occurs over most of the ocean floor, at depths above
4,000 m. These have laminar stratifications, with thicknesses ranging from millimeters
to decimeters. These deposits of polymetallic nodules and crusts are estimated to cover
an area of approximately 6.4 x 106 km2. These polymetallic nodules are rocky concretions
formed by concentric layers of iron and manganese hydroxides which develop from a core
which can be a fragment of rock, remains of biogenic origin such as shark teeth or
shells of organisms such as radiolaria and even fragments of old nodules. In their
chemical composition, polymetallic nodules have strategic metals such as nickel, cobalt
and copper, as well as the presence of rare earths, metals widely used today for
technological and economic development in industrialized countries. This study
demonstrates the development of nodes and the strategic and economic value of their
exploration. These deposits have an economic value of world importance due to the
numerous chemical elements that make up their composition. Keywords: polymetallic
nodules, nodule occurrence, nodule formation.

Recursos Minerais da Água do Mar
Authors: Calliari Lauro Júlio
Published: October 2023

A água do mar contém grandes quantidades de minerais valiosos, alguns dos quais
são muito escassos e caros em sua forma terrestre. A maioria dos minerais que desejamos
ocorre em combinação com outras substâncias, neste caso como soluções na água do mar.
Esta situação é o maior problema em nosso aproveitamento de água do mar como riqueza
mineral. Os minerais são tão disseminados que a maioria não atende à definição
normalmente aceita de minério - um elemento mineral ou composto de elementos de valor
suficiente em quantidade e qualidade que possa ser extraído com lucro. Devido aos
problemas recentes associados às indústrias de mineração terrestre, como resultado do
esgotamento de minérios de alto teor, demanda sustentável de água e energia e questões
ambientais, a mineração de água do mar está se tornando uma opção atraente. No entanto,
alguns minerais que apresentam altas concentrações são extraídos atualmente. Este
capítulo apresenta uma síntese dos processos de extração do sal comum, do magnésio, do
bromo e por fim, do recurso mineral que poderá ser num futuro próximo o bem mais valioso
do oceano: a água potável. Palavras-chave: extração de sal e magnésio, dessalinização,
água doce. Abstract Seawater contains large amounts of valuable minerals, some of which
are very scarce and expensive in their terrestrial form. Most of the minerals we want
occur in combination with other substances, in this case as solutions in seawater. This
situation is the major problem in our use of sea water as mineral wealth. Minerals are
so disseminated that most do not meet the commonly accepted definition of ore - a
mineral element or compound of elements of sufficient value in quantity and quality that
it can be extracted profitably. Due to the recent problems associated with the onshore
mining industries, as a result of the depletion of highgrade ores, sustainable demand
for water and energy, and environmental issues, seawater mining is becoming an
attractive option. However, some minerals that have high concentrations are currently
extracted. This chapter presents a synthesis of the processes of extraction of common
salt, magnesium, bromine and finally, the mineral resource that may in the near future
be the ocean's most valuable asset: fresh water. Keywords: salt and magnesium
extraction, desalination, fresh water.

Published: October 2023

This study aimed to investigate the effects of Nanta activities based on an integrated approach involving music and movement on the socio-emotional competence of preschool children and whether these effects vary according to the children's ages. To achieve this, a total of 65 children aged 3 and 4 years were selected as the research participants, and they were randomly assigned to either an experimental group or a control group on a classroom basis. The experimental group engaged in Nanta activities twice a week for a total of 16 sessions, with each session lasting 30 minutes. The control group, during the same period, participated in the regular program of the preschool. Before and after the Nanta activity sessions, a Social Competence and Behavior Evaluation (SCBE) assessment was conducted for both groups. The collected data were analyzed using SPSS for Windows, including frequency analysis, independent samples t-test, paired samples t-test. and covariate analysis. The results of the study indicated that Nanta activities had a significant effect on overall socio-emotional competence enhancement in preschool children. Furthermore, significant effects on enhancing overall socio-emotional competence, as well as sub-domains including prosocial behavior enhancement and reduction in internal and external behavior problems, were more pronounced in the 3-year-old group compared to the 4-year-old group. By demonstrating the effectiveness of Nanta activities that integrate music and movement in enhancing the socio-emotional competence of 3- and 4-year-old preschool children, this study provides foundational data that can be utilized for the development of programs aimed at promoting socio-emotional development in young children.

Authors:   The Korea Associantion For Early Childhood Education Administration, Kim Yoon-Keong , Kim Seung-Hee
Published: October 2023

The purpose of this study was to investigate the mediated effect of teacher-child interaction on the effects of early childhood teachers’ job stress on young children’s social development. The subjects of this study were 297 early childhood teachers who were teaching 5-year-old children in Gwangju metropolitan city and Jeollanamdo. This study conducted survey research, and the survey data were analyzed using frequency analysis, descriptive statistic analysis, t test, F test, Pearson correlation analysis, and multiple regression analysis. The results of this study were as follows: First, early childhood teachers’ job stress, young children’s social development, and teacher-child interaction were meaningfully different according to teachers’ background variables such as teachers’ work experience, academic ability, marital status, and the number of overtime work. Second, there was negative correlation between early childhood teachers’ job stress and young children’s social development, between early childhood teachers’ job stress and teacher-child interaction. Third, early childhood teachers’ job stress had a significant negative effect on young children’s social development. Fourth, teacher-child interaction had a mediated effect on the effects of early childhood teachers’ job stress on young children’s social development. This indicates that the negative effects of early childhood teachers’ job stress on young children’s social development can be relieved through teacher-child interaction. It is important before everything for teachers to interact with young children effectively for young children’s social development. As a result, it is significant that this study suggests the method to minimize the negative effects of early childhood teachers’ job stress on young children’s social development by verifying the mediated effect of teacher-child interaction.
