Authors: Muhopilah Pipih , Tentama Fatwa
Published: August 2022

Parenting is classified into several types, one of which is authoritarian parenting. Verbal hostility, corporal punishment, nonreasoning / punitive strategies, and directiveness are characteristics of this parenting style. The construct validity and construct reliability of the authoritarian parenting scale, as well as the characteristics and indicators that reflect authoritarian parenting, are being investigated. This study included all students in class VIII at Yogyakarta’s state junior high schools X, Y, and Z, which totaled 524 students. This study’s sample size was 185 students. The sampling technique employs cluster random sampling. Data is gathered using an authoritarian parenting scale. The research instruments are distributed directly to the subject. Structural Equation Modeling (SEM) was used to analyze the research data in the SmartPLS 3.2.8 program. The data analysis results of this study show that the characteristics and indicators that reflect authoritarian parenting are valid and reliable. The most dominant aspect that reflects authoritarian parenting is corporal punishment, while directiveness is the weakest aspect that reflects authoritarian parenting. As a result, because the theory describing the construct of authoritarian parenting corresponds to empirical data obtained from the subject, the measurement model can be accepted.

Authors: Firman Nurinas Dzakiyah , Lukman Lukman , Firdaus Faradillah
Published: August 2022

Late adolescents are reported to have poor perspective-taking. This study aimed to determine whether an improvement to perspective-taking is achieved after participants read fiction, and whether a transportation process is involved in it. The participants in this study were late adolescents (17-22 years old) with poor perspective-taking and certain degrees of experience and interest in reading fiction (N = 8). This study used a pretest-posttest-follow-up design. The Friedman test results show that there is a significant difference in the perspective-taking scores of participants before and after receiving manipulation in the form of supply of fiction reading media (p = 0.002, ̄x pretest = 11, ̄x posttest = 37.25, ̄x follow-up = 37.1). The simple regression analysis test results show that the improved perspective-taking is not influenced by the occurrence of transportation in participants when reading fiction (p = 0.072, r = 0.175, β = 0.473). The participants showed improved perspective-taking right after the manipulation treatment was given, but slightly declined in the subsequent week.

Water-based adhesive was one of the most important media for bonding substrates to one another because of their environmental friendly character. Previously, in the application of hardwood adhesives such as Ulin and Merbau, the type of adhesive used was a two-component system. For this reason, a one-component water-based adhesive was introduced in this study. The advantage of these was environmental friendly and high durability. In this application, delamination was one of the important parameters to determine whether the adhesive used was well penetrated or not. For this reason, delamination will be the main parameter in this study. This research includes the preparation of tools and materials, manufacture of PVA (polyvinyl alcohol) solution, polymerization of polyvinyl acetate by mixing the main raw material of vinyl acetate monomer and PVOH solution using APS (ammonium persulfate) initiator. The polymerization process was carried out at 1 atm pressure and 75oC – 80oC temperature accompanied by stirring with ±500 rpm rotation rate. Final product is a homopolymer PVAc (polyvinyl acetate) with PVOH Z-210 with AAEM (acetoacetoxy ethyl methacrylate) content having an acetoxy functional group. A delamination test was carried out on the final product with a modified test based on Japanese Agricultural Standard 1152 where the product was immersed in water for 360 minutes, then placed in an oven at 40oC for 18 hours. Samples using PVOH with AAEM content have an average delamination rate of 0.67-1.67% while existing products on the market have an average delamination rate of 45.83-52.08%.

Johar plant is a type of plant from the Fabaceae family which is widely used in traditional medicine such as malaria, itching and diabetes medicine. This study aims to determine the antibacterial activity of Johar stem bark extract with different levels of solvent polarity on the growth of Staphylococcus aureus and Escherichia coli bacteria and to determine the active compound class by TLC-Bioautography. The extraction of active compounds used a multilevel maceration method starting with n-hexane (non polar), followed by ethyl acetate (semi-polar) and ethanol (polar) solvents. Antibacterial activity testing was carried out by diffusion well method with a concentration variant of 25% and 50%. The results showed that n-hexane, ethyl acetate, and ethanol extract had antibacterial activity against the two test bacteria. Ethyl acetate and ethanol extract from Johar stem bark at a concentration of 50% were classified as very strong antibacterials with inhibition zone diameters against S. aureus, which were 22.02±0.84 mm and 20.16±0.23 mm, respectively. The results of the TLC-Bioautography test showed that the three test extracts had strong antibacterial activity against S. aureus and E. coli. In the n-hexane extract with n-hexane: ethyl acetate (9:1) eluent using Lieberman-Burchard spray reagent, it was suspected that triterpenoid compounds were present. In ethyl acetate extract with n-hexane: ethyl acetate (6:4) eluent and ethanol extract with chloroform: methanol (8:2) eluent using FeCl3 1% spray reagent, it was suspected that the tannin compound was present in both extracts.

Apricot kernel skin (AKS) has not been fully utilized except a few used
as feed. In this study, the effect of extrusion pretreatment on the
extraction yield and acid value of AKS oil (AKSO) was investigated, and
the physicochemical properties, the composition of fatty acids and
triglycerides, the sn-2 fatty acids distribution, and the content of
various active ingredients in AKSO were further analyzed for the first
time. The results showed that AKS has 12.10% crude oil. AKSO contains
89.72% unsaturated fatty acids and is rich in tocopherols,
phytosterols, squalene and polyphenols. After AKS was extruded,
granulated, and extracted with hexane as a solvent, the acid value of
AKSO was significantly reduced and the extraction yield was 11.97%,
which confirmed its feasibility for the extraction of AKSO. From the
point of nutrition and cost-efficiency, AKS is a very promising
potential new oil-bearing resource, and AKSO can be used as a
nutritional oil in food, medicine or cosmetics.

Specific background information on cancer patients affected more
severely by crisis and disasters is lacking. We experienced an advanced
breast cancer patient whose hospital visits were interrupted for two
years due to multiple internal and external factors. These factors need
to be taken more into account for breast cancer management.

Background Acute Lymphoblastic Leukemia (ALL) represents around
70% of pediatric leukemia. In high-income countries, 5-year survival is
above 90% but survival in low-and middle-income countries is inferior.
Objective: To document the treatment outcome and prognostic
factors of Pediatric ALL in Pakistan. Materials and methods: in
this descriptive study, all newly diagnosed cases of ALL/LBL from one to
16 years of age enrolled between 1 January 2012 to
31 December 2021 were included. The treatment was
based on the standard arm of the UKALL2011 protocol. Results:
Data of 945 cases of ALL, including 597 males (63.2%) was analyzed. The
mean age at diagnosis was 5.73 ± 3.51 years. Pallor was the commonest
presentation in 95.2% followed by fever in 84.2% cases. The mean white
blood cells count was 56.6 ± 103.4 x10 /L.
Neutropenic fever followed by myopathy was the most common complication
during induction. In univariate analysis, high white blood cells count
(P=<0.001), intensive chemotherapy (P=<0.001),
malnutrition (P=0.007), poor response to induction chemotherapy
(P=0.001), delay presentation (P= 0.004), use of steroids before
chemotherapy (P=0.023) significantly adversely affected overall survival
(OS). Delayed presentation was the most significant prognostic factor in
the multivariate analysis (P = <.002). After a median
follow-up of 54.64 ± 33.80 months, the 5-year OS and DFS was 69.9% and
67.8%, respectively. Conclusion. In this largest cohort of
childhood ALL from Pakistan, a high WBC count, malnutrition, delayed
presentation, prior steroids use, intensive chemotherapy and poor
response to the induction chemotherapy were associated with decreased OS
and DFS rates.
Perceptions of the Stressful Job Search for Pediatric Hematology/Oncology Fellows

The PHO workforce landscape has been evolving over the past decades,
with concern for waning interest in the subspecialty. In this study, we
aimed to evaluate perceptions of the PHO workforce (both fellows and
faculty), the experience of seeking an initial faculty position, and its
impact on fellow stress and anxiety. An anonymous survey consisting of
demographics, job search experiences including barriers and helpful
tools, and emotional health impacts such as stress and anxiety was
developed and distributed to all PHO fellowship programs. Seventy-nine
fellows and 83 faculty responded. Faculty were less likely than fellows
to perceive that fellows are struggling to find jobs ( P=0.0198).
However, faculty were more likely than fellows to perceive that fellows
are either “extremely stressed” or “stressed” due to job search (
P=0.0003). By June 2021, 30 of 44 (68%) candidates had been
offered a position, and 80% of those had accepted. There were no
significant associations between fellow stress level and job offering,
proximity to their ideal goals, or change in career type. Common
barriers to the job search included geographic constraints and partner
employment. Respondents identified centralized job listings, formal
training on career development strategies, introduction to various
career paths, and more transparency about the job search as needed
interventions. The perception of difficulty and stress regarding the job
search is endorsed by most, identifying a need for more interventions to
improve the job search experience. These data also highlight unmet
mentorship and educational needs among PHO fellows in preparing for the
job search.
