Trade receivables represent bills arising from the sale of merchandise or services on credit. Trade receivables are usually given by sales to buyers on the basis of trust, without being accompanied by a written agreement, except for certain customers such as sub-distributors. The impact of uncollectible accounts is that it causes a risk of decreasing company profitability, which in turn can cause losses for the company. Uncollectible receivables are debts owed by other parties for a business transaction. The type of research used in this study is a qualitative descriptive research method, using secondary data collected through the process of observation, interviews and documentation at PT. Tri Sapta Jaya Sibolga. The following data analysis techniques used are data reduction, data presentation, drawing conclusions and triangulation. In the results of interviews with PT.

The use of natural material, such as mas ngur oyster (Atactodea striata) as traditional medicine has been long known by people in Kei Islands–Southeast Mallucas. This study is aimed at measuring the ability of active compounds of this oyster extract in reducing NF-κB and TNF-α expression and showing the histological image of indomethacine-induced rat ileum with IBD after treatment with mas ngur oyster extract. It used 8-12 week old male rats (Rattus norvegicus) of 150 - 200 g BW. The rats were divided into 3 groups, healthy group, sick group (induced with 15 mg/kg BW of indomethacine), and treatment group (orally induced with indomethacine at a dose of 15 mg/kg BW then treated with mas ngur oyster extract at the dose of 100, 400, 700 mg/kg BW). Indomethacine induction at the dose of 15 mg/kg BW and mas ngur oyster extract therapy were orally administered. NF-κB and TNF-α expressions were measured using immunohistochemicals, and the histological image used Hematoksilin-Eosin staining. Results showed that extract therapy gave significant effect (P<0.05) at the effective dose of 400 mg/kg BW that could reduce 86.421% of NF-κB expression and 60.972% of TNF-α expression in the rat ileum and result in tissue recovery of the IBD rat’s ileum after the therapy.
Impact of Positive Organizational Behavior on Self-Efficacy in Improving The Quality of Work of PT Kareta Sabila Employees
Authors: Guslina Indri
Published: March 2023

Positive Organizational Behavior has a wide reach, from the organization's past buried in by business ideology, through the present with urgent needs and emerging opportunities. This qualitative study aims to find out positive organizational behavior on self-efficacy. Positive Organizational Behavior is not just explicit knowledge, skills, and abilities that can only be built through educational and training programs, or even through work experience. Positive Organizational Behavior is also not equivalent to organization-specific tacit knowledge built by managers and employees over time by taking time and immersing themselves in the socialization process to build motivation in improving the quality of employee work. Positive Organizational Behavior also brings new and exciting opportunities above and above that are provided by social relationships and networks across individuals, departments, and organizations. Positive Organizational Behavior has triggered a paradigm shift far from just a negative emphasis on pathology that fills handbooks, dictionaries and classification systems of clinical psychologists. Similarly, Positive organizational behaviour offers organizational behaviour and human resource management researchers and practitioners a new positive perspective, far from the 'gloom and doom' focusing on dysfunctional employees, aggression in the workplace, incompetent leaders, stress and conflict, unethical behaviour, ineffective strategies and counterproductive organizational structures and cultures

DC Motor Controller Using Full State Feedback
Authors: Setiawan Naufal Rahmat , Ma'arif Alfian , Widodo Nuryono Satya
Published: March 2023

This paper discusses the implementation of a full state feedback control system on DC motors to stabilize the speed of DC motors and fight the disturbances given to DC motors. Modern controls such as full state feedback use 2 sensor inputs, namely the Hall effect speed sensor OH42E and the INA219 current sensor and use 3 parameters namely K1 (Constant 1), K2 (Constant 2), and KI (Integral Constant) in designing the controller, the goal is to get a good system response according to the desired design specifications. The test was carried out with a hardware-in-the-Loop (HIL) scheme which uses an Arduino microcontroller as a DC motor plant control device in the form of a control mathematical model entered in the Arduino IDE software and by trial and error to find the desired response value. The test results showed that at the values of K1=1, K2=1, KI=0.9, a stable system response was obtained with tr(s)=3, ts(s)=4, and Os(%)=7% The addition of an integral constant () value affects a short rising time but is inversely proportional to a high overshoot value as well. Varying the values of K1 and K2 as multipliers on the sensor values has an impact on the stability of the system response or oscillations. The stability of this system response indicates that full state feedback can be relied upon as a control system.

I med- og modspil
Authors: Rasmussen Hanne Fie , Mikkelsen Stinus Storm
Published: March 2023

I denne artikel undersøges det empirisk på baggrund af lærerinterviews, hvordan lærere forstår og håndterer den indholdsmæssige kompleksitet, der findes i projektorienteret undervisning, med særligt fokus på de funktioner, digitale teknologier får i forløbene. Artiklens analyser peger på, at selv i højt rammesatte problemorienterede forløb udvikler, forskyder og forandrer det indholdsmæssige fokus sig over forløbets faser. Autentiske problemer lader sig vanskeligt inddæmme af skolens fag og fagligheder, og andre typer viden end den traditionelle skolastiske bliver relevant. Dét er undervisningsformens styrke – men det vanskeliggør også lærerens opgave med at kvalificere elevernes arbejde og understøtte en systematisk kundskabsudvikling. Samtidig har lærernes teknologivalg betydning for de måder, hvorpå undervisningens indhold forandrer sig, ligesom indholdets uforudsigelighed også kan stille foranderlige og uventede krav til teknologiernes funktioner og design.
Affektiv literacy og digitale teknologier
Authors: Jensen Michael
Published: March 2023

Denne artikel handler om literacy og digitale teknologier – om hvad det vil sige at skrive og læse i en digitaliseret hverdag. Med begrebet digital literacy diskuterer artiklen digitaliseringens implikationer for uddannelse, danskundervisning og hverdagens skrivere og læsere. I et posthumant perspektiv argumenteres for nødvendigheden af at udvikle mere nuancerede og adækvate tilgange til digital literacy. For at det kan ske, er det nødvendigt dels at udfordre forestillingen om den autonome, selvstyrende skriver og læser, dels at gøre op med den bag-vedliggende humanistiske og antropocentriske forståelse af digitale teknologier. Med afsæt i affektteorien er målet at etablere en affektiv og postkritisk literacy. Artiklens bud på en opdateret digital literacy i uddannelse og danskundervisning er en respons-abilitet, der ikke først og fremmest handler om at designe, analysere og kritisere, men mere om at træde i et etisk og affektivt forhold til teknologi.

Authors: Zhang Xiaoxia , Moss Samantha , Gu Xiangli
Published: March 2023

Background of the study: The COVID-19 pandemic has deeply impacted people’s daily lives, while the influence on behaviors and mental health among college students at the early stage of this pandemic is rarely studied. Objective: This study examined the impact of the COVID-19 pandemic in the early stage on college students’ physical activity (PA), sedentary behavior, and depressive symptoms and its impact on sex and ethnic disparities in these outcomes. Methods: Using a cross-sectional design, 111 college students were recruited, and the data were collected before COVID-19 (n = 64) and in the early stage of the COVID-19 pandemic (n = 47), respectively. All participants completed a survey measuring depressive symptoms and wore an accelerometer to monitor PA behavior (light PA [LPA], moderate-to-vigorous PA [MVPA]), and sedentary behavior. Results: More MVPA engagement and lower levels of depressive symptoms were observed in the early-stage COVID-19 group compared to the before-COVID-19 group. The magnitude of the sex and ethnicity disparities in PA and depressive symptoms were reduced in the early-stage of the COVID-19 pandemic. Conclusion: Understanding college students’ behaviors and mental health in the midst of a global crisis can be useful to determine appropriate strategies to address health and wellness in the chance of the lockdown returning and to further promote this vulnerable population’s physical and mental wellness.

Authors: Walter Sibi , Daneshfar Amin , Petersen Carl
Published: March 2023

Background: Clubbells were popular shoulder exercise equipment used during the 17-18th centuries. Currently there is a resurgence in the use of clubbells to strengthen the shoulder rotators, but there are no studies to prove their effectiveness on shoulder kinematics. Therefore, this study aimed to find out if clubbell exercises had any effect on glenohumeral rotational range of motion (ROM) and shoulder rotator strength. Methods: Using a randomised control study design, female handball athletes (n=15) were voluntarily recruited and were assigned randomly to either a handball training only group (HT) (n = 8, age 25±7 y, height 1.77 ± 0.11m, mass 76 ± 15 kg,) or a shoulder exercise group (SE) (n = 7, age 27±8 y, height 1.78 ± 0.12m, mass 79 ± 15 kg). The SE group underwent an exercise programme (8 weeks, 3 days/week, 20 min/day) using clubbells. The ROM and muscle strength were assessed at baseline and at the end of weeks 2, 4, 6 and 8. Results: After eight weeks, comparison between groups showed that the SE group’s dominant arm internal rotators muscle strength improved (28±5 to 33±7 Nm) significantly (p0.05). Within the SE group, internal rotation ROM, internal rotators, and external rotators muscle strength all significantly (p0.05) improved. Conclusions: Clubbell exercises increases internal rotation ROM and shoulder rotators muscle strength. Therefore, it is suggested that handball athletes could use clubbell exercises to improve their shoulder rotational ROM and strengthen the shoulder rotators whereby reducing shoulder injury risk.

Background: Altering moderator variables during a jump rope training (JRT) program can provide a novel training modification that can be used to modify the specific training outcomes. JRT is commonly implemented as a traditional game activity in many countries as an old culture of physical activity in school-age participants (SAP). However, strength and conditioning professionals need to know how JRT moderator variables affect these health- and physical fitness outcomes. Thus, an evidence-gap map (EGM) could provides a clearer picture of the design of an appropriate JRT based on scientific evidence. Objective: the purpose of this systematic review secondary analysis was to assess the moderator variables related to JRT effectiveness for health and physical fitness-related outcomes in SAP. Method: literature searches were conducted in the following electronic databases: PubMed, Web of Science and SCOPUS. The PICOS (participants, intervention, comparators, outcomes, and study design) approach was used to rate studies for eligibility. An EGM was constructed to graphically represent the body of evidence and the current research gaps. Results: 10,546 records were initially identified and finally, 8 studies were considered. A total of 186 participants were analysed in the intervention groups (16 groups). Five of Eight studies measured health-related parameters and five of eight included fitness-related parameters. Conclusion: rope weight (e.g., weighted rope i.e. 695 g), adequate post-exercise recovery strategies (e.g., dark chocolate supplementation), type of jump (e.g., freestyle), and total number of jumps, can be

Background: Abdominal adiposity is associated with high risk of cardiometabolic diseases. Waist circumference has been used as a surrogate measure of abdominal adipose tissue in both youth and adults. Objectives: The present study evaluated whether cardiorespiratory fitness and leg power (LP) were independently associated with abdominal adipose tissue in 12-16-year-old Nigerian adolescents. Methods: This cross-sectional study comprised 2047 (1087 girls and 960 boys) adolescents who were evaluated for cardiorespiratory fitness and leg power. The cardiorespiratory fitness and leg power were assessed using the progressive cardiovascular endurance run (PACER) test and the vertical jump (VJ) test, respectively. Abdominal adiposity was evaluated with the waist circumference (WC). Regression models controlling for age and maturity status were used to assess the association of fitness and LP with WC. Results: Low leg power had significant negative association with the risk of abdominal adiposity in both girls (β=-0.307; p0.001) and boys (β=-0.262; p0.001). The observed relationship was independent of fitness, whereas the relationship between fitness and risk of abdominal adiposity was partly determined by leg power. Conclusion: Leg power and fitness were independently associated with the risk of abdominal adiposity in adolescents, but the association of leg power was stronger in girls. Health promotion efforts targeting reduction of abdominal adipose tissue should also include muscular power training type activities in addition to endurance-related activities.

Background: Obesity is a major public health issue in the United States (U.S.), affecting an estimated 78 million US adults. Aerobic exercise (AE) is recommended by the American College of Sports Medicine to prevent and treat obesity, yet the effects of AE on circulating hunger hormones including acylated ghrelin and its biological catalyst, ghrelin o-acyltransferase (GOAT) are less known. Objectives: We investigated the effects of AE on circulating concentrations of appetite regulating hormones and GOAT in a pilot sample of adults classified with normal weight (NW) and obese (OB) body weight status. Methods: Using a quasi-experimental design, nine adults with NW (n=4, body mass index [BMI] = 21.3±1.2 kg/m2) and OB (n=5, BMI = 38.9±6.2 kg/m2) body weight status completed a preliminary health/fitness assessment. Participants returned to the laboratory on three separate occasions, separated by ≥ 48 hours to perform cycle exercise at 30% and 60% oxygen uptake reserve (VO2R) or a seated control session with no exercise for 40 min. Fifteen mL of blood was taken pre-and-post exercise and control and were assayed in duplicate. Nonparametric procedures determined whether mean rank differences existed between NW and OB for acylated ghrelin, leptin, insulin, and GOAT in response to exercise and control. Alpha levels were set a priori to p 0.05. Results: Significant mean rank reductions were found in GOAT after compared to before AE and control for NW and OB (p.05). Significant mean rank differences were found in acylated ghrelin after compared to before performing AE at 60% VO2R in NW and OB (p.05); however, differences were not observed between NW and OB (p.05). Conclusions: Our findings reveal the first available data regarding the effects of AE on GOAT, with NW and OB experiencing equivocal changes pre-to-post AE at 60% VO2R, and in response to a seated control session.

Published: March 2023

Introduction: Irreversible hydrocolloid alginate impressions are among the widely used impression materials in dentistry but they suffer from one major drawback, i.e., dimensional change after setting. Because of clinical limitations, impressions are poured to make cast after a time delay which is so long as compared to the recommended period. This can be reduced by storing the impression material in different storage environments. Aim: To assess the impact of the storage environment on the dimensional accuracy of alginate impression material. Materials and Methods: In this in-vitro study, 70 samples were made with chromatic alginate impression material according to the manufacturer’s guidelines and divided into seven groups (Exposed to atmosphere, Airtight container in the refrigerator, 2% NaCl Solution, Air-tight container, Distilled water, 1% K2 SO4 Solution and Mixture of 2% NaCl and 1% K2 SO4 Solution). Samples were made with stainless steel die fabricated according to ADA specification 18 and dimensions were noted after 24 hours of storage. Distance between the cross lines was calculated using are profile projector. ANOVA Test and Tukey Test were applied to compare the mean dimensional change of seven groups and to compare the difference in mean dimensional change between the groups. Results: Samples kept in a solution of 1% K2 SO4 and 2% NaCl solution had no significant dimensional change (F-value 2026.0, p-value <0.001), whereas samples stored in open-air resulted in the greatest dimensional change (Group 7 > Group 6 > Group 3 >Group 4 >Group 2 >Group 5 >Group 1). Conclusion: The impressions which are kept in a combined solution of 1% K2 SO4 and 2% NaCl have shown the best impact on the dimensional accuracy of alginate impression materials. However, these can also be seen in 1% K2 SO4 or in 2% NaCl solutions respectively

Mucuna pruriens seed is an underutilized legume with good nutritional value with a possibility of changes in its micronutrients’ composition during processing whose data is scanty. Mucuna pruriens seed flour was therefore evaluated for the effect of soaking, cooking, roasting, germination and fermentation as well as some double treatments on its vitamin and mineral contents. Mucuna pruriens seeds were cleaned, washed, soaked, cooked, roasted, germinated and fermented. Vitamins and minerals composition were determined. Soaking, cooking and roasting significantly reduced (p<0.05) all the vitamins. Vitamin B9 was significantly (p<0.05) reduced the most with a range of 0.28 – 21.88 mg/100g. Vitamins B1, B2, B3 and B12 were significantly increased by fermentation with vitamin B2 increased the most (0.26 to 1.50 mg/100g; represents 577% increase). Vitamin B9 was the most significantly reduced (p<0.05) from 21.88 to 0.28 mg/100g by 72 h fermentation. Cooking reduced all the minerals except potassium and sodium. Potassium was increased from 690.50 to 930.75, 760.50 and 730.00 mg/100 in 10, 15 and 20 minutes roasted samples respectively. Germination significantly (p<0.05) reduced all the minerals except 24 h germination which increased calcium from 218.17 mg/100g in the raw Mucuna pruriens seed to 234.36 mg/100g. Fermentation generally reduced all the minerals significantly (p<0.05) except calcium and zinc. Germination and fermentation have proved to be suitable methods for the enhancement of vitamin B2, B3, B12 and zinc in Mucuna pruriens seed flour. Combined process treatments reduce most vitamins and minerals in M. pruriens seed flour and are therefore not suitable for their improvement.

Published: March 2023

The main focus of this study is to introduce a new category of generalized closed sets, referred to as \(\mathcal{I}_\mathcal{p}\)- closed sets, within the framework of ideal topological spaces. By using a few instances, we demonstrate \(\mathcal{I}_\mathcal{p}\)- closed sets and establish some fundamental properties of \(\mathcal{I}_\mathcal{p}\)-closed sets. We also investigate the relationship between \(\mathcal{I}_\mathcal{p}\)-closed sets and other classes of generalized closed sets in ideal topological spaces, such as (\mathcal{I}_\mathcal{g}\)- closed sets, \(\alpha\)\(\mathcal{I}_\mathcal{g}\)-closed sets, and  (\mathcal{I}_\mathcal{r}\)\mathcal{g}\)-closed sets. Then, we focus on the topological implications of \(\mathcal{I}_\mathcal{p}\)-closed sets and investigate how they relate to the concepts of \(\mathcal{I}_\mathcal{p}\)-continuous map,  (\mathcal{I}_\mathcal{p}\)-irresolute map, and a strongly \(\mathcal{I}_\mathcal{p}\)-continuous map. First and foremost, we define the \(\mathcal{I}_\mathcal{p}\)-continuous map, investigate the behavior of \(\mathcal{I}_\mathcal{p}\)- continuous map with respect to \(\mathcal{I}_\mathcal{p}\)-closed sets, and derive several important properties of \(\mathcal{I}_\mathcal{p}\)-continuous map. Further, we studied their relationships with other classes of continuous maps in ideal topological spaces. Nevertheless, we defined the definitions of \(\mathcal{I}_\mathcal{p}\)-irresolute maps and strongly \(\mathcal{I}_\mathcal{p}\)-continuous maps in ideal topological spaces. We explored the connections with the notions of \(\mathcal{I}_\mathcal{p}\)-continuous map,  (\mathcal{I}_\mathcal{p}\)-irresolute map, and a strongly \(\mathcal{I}_\mathcal{p}\)-continuous map. Our results provide new insights into the study of ideal topological spaces.
