Purpose: This study aims to determine the effect of broadband access, education level, population numbers, and investment on the unemployment rate in Indonesia. Research design, data, and methodology: This study uses panel data from 34 provinces from 2016 to 2019. The analysis uses the fixed-effect model for panel data with the Feasible Generalized Least Square (FGLS) estimation method. Results: Broadband access has a negative and significant effect on the unemployment rate. Mean years of school, population, and foreign direct investment also have a negative and significant impact on the unemployment rate. In contrast, the domestic direct investment variable has a positive and significant effect. Conclusion: The availability of broadband access in an area allows easier and faster access to information. The ease of access to such information can affect producing goods and services, encouraging innovation and employment growth, and reducing the unemployment rate. This research recommends that the government intensify the Indonesia Broadband Plan policy to accelerate the development and equitable distribution of broadband access in all regions of Indonesia.

Hijabs are predominantly worn in hot environments, but very rare studies on the thermo-physiological effects of wearing hijabs are found. We investigated the effects of wearing rayon and polyester hijabs on wearers’ physiological and subjective responses in warm-humid and hot-dry environments. Eight females (25.0 ± 2.3 y in age, 157.7 ± 4.1 cm in height, and 50.8 ± 7.5 kg in weight) participated in three conditions (No hijab, rayon hijab, and polyester hijab condition) during exercise in two thermal environments: a warm-humid (30 °C and 70%RH) and a hot-dry environment (36 °C and 30%RH), which generated an identical wet-bulb globe temperature at 27 °C. The results showed that no differences in rectal temperature were found among the three clothing conditions or the two environments, whereas auditory canal temperature was higher in the hot-dry than in the warm-humid environment ( P < 0.05) with no differences between the polyester and rayon hijab conditions. Mean skin temperature and neck temperature were higher for the polyester condition than for the rayon condition in the warm-humid environment ( P < 0.05). Sweat rate was greater for the polyester hijab condition than for the no hijab condition in the warm-humid environment ( P = 0.049). Heart rate was greater for the polyester hijab condition than for the other two conditions in the warm-humid environment ( P < 0.05). Subjects felt more thermally uncomfortable when wearing the polyester hijab than the rayon hijab in the warm-humid environment. Greater thermal burden of the polyester hijab when compared to the rayon hijab was marked in the warm-humid environment, not in the hot-dry environment.

The present study developed a test protocol for evaluating the mobility of firefighting chemical and flame personalprotective equipment (PPE) for the National 119 Rescue Headquarters in Korea and suggested ergonomic design factors toimprove their mobility and performance. Six types of PPE were employed, including three types for flame protective PPE(5 ~ 6 kg excluding the self-contained breathing apparatus), and three types for chemical and flame protective PPE (8 ~11 kg). These PPEs are used by the 119 Rescue firefighters. Three male firefighters (34.3 ± 1.2 y in age, 175 ± 8 cm inheight, 81 ± 13 kg in body weight) participated in the mobility test and interview. A mobility test protocol consisting of 16components (nine postures and seven motions including a dexterity test) along with a visibility test were developed basedon pre-interviews and literature reviews. The findings indicated that the clothing microclimate humidity on the neck andchest exceeded 85%RH on average for all the six PPE conditions, with the chest area reaching as high as 98%RH. This highhumidity caused fogging inside the visor and impaired visibility. The requirements for improving the PPE design in termsof mobility varied depending on whether it was the separated types or all-in-one types, particularly regarding the hood andgloves design. The findings of this study can be applied to improve the design of Level A_PPE for firefighters. The mobilitytest protocol and visibility test developed in this study can also be applied to other types of Level A impermeable PPE.

PURPOSE: Older adults experience a degenerative process that causes several health problems such as an increased risk of falling due to poor balance. However, to reduce the risk of falling exercise is used as an early intervention. The study aimed to understand the differences in the effect of single-leg stance exercises and bridging exercises with core stability exercises on increasing balance in older adults. METHODS: A quasi-experimental study was conducted at the Salus Medica Physical Medicine and Rehabilitation Clinic using a sample of 30 individuals divided into two groups. The interventions were conducted twice weekly for one month. The evaluation included first, middle, and final evaluations using the Berg Balance Scale. Moreover, the statistical test was used to determine the effect of intergroup administration on increasing the balance of older adults, whereas the independent t-test was used to determine the effects of intergroup administration on increasing balance among older adults. RESULTS: The results of the repeated-measures analysis of variance revealed that the p-value assumed sphericity in both groups (p=.000), which implies that the two groups improved the balance of the older adults. The independent t-test identified that the p-value equal variances were assumed (p=.572), which indicated no difference in the effect between the two groups in increasing the balance of older adults. CONCLUSIONS: No significant difference between single-leg stance exercises with core stability exercises and bridging exercises with core stability exercises in improving balance among older adults was observed.

Background: Among women who can have children, bacterial vaginosis (BV) is the most common cause of abnormal vaginal discharge. Due to its high prevalence and morbidity, it is crucial to prevent BV by addressing its risk factors. Objective: This study aimed to determine the incidence and determinants of BV in the sexually transmitted infection (STI) division of the Dermatovenereology Department at Dr. Soetomo Hospital in Surabaya. Methods: This retrospective analytical observational study was conducted using a cross-sectional approach. Electronic data from 56 patients were included in the study, covering the period from 2019 to 2022. The patients were divided into two groups: BV patients and controls. BV patients were diagnosed with BV by fulfilling three out of four Amsel criteria, while controls with typical vaginal discharge. Results: The study included 34 BV patients and 22 control patients. Bivariate analysis showed a significant correlation between the incidence of BV and the number of sexual partners (p = 0.009) and the use of intrauterine devices (IUD) (p = 0.002). Multivariate analysis confirmed that both factors were determinants of BV incidence, with IUD use being the most dominant determinant (95% CI 1.86~135.02, p = 0.01). Conclusion: The study found that the use of IUDs and the number of sexual partners significantly determined BV incidence.

Purpose: Post-purchase service in online platforms has created an exciting focus for consumer behavior studies. This study intends to ascertain the impact of post-purchase shipping dimensions (shipping service, tracking service, return service, and customer care) on customer satisfaction and behavior intention. The authors developed a new model considering behavioral intention as the endogenous variable integrated framework of previous studies. Research Design and Methodology: The total sample is 223 respondents, selected using purposive sampling. The data collection uses Google Forms and is analyzed using AMOS Structural Equation Modeling (SEM). Results: Our findings showed shipping, tracking, returns, and customer service positively impact customer satisfaction, and customer satisfaction mediates shipping, returns, and customer service on customer behavior intent. Furthermore, customer satisfaction does not affect the effect of tracking service on customer behavior intention. Conclusion: Our hypothesis of the relationship between the postpurchase dimension and customer satisfaction was supported. However, only two of our three mediating hypotheses are supported. The mediating effect of customer satisfaction on the post-purchase dimension on behavioral intention is insignificant, while their direct relationship was significant. It showed that, concerning tracking service, customer satisfaction is not a requirement for the customer to perform behavioral intention in an e-retail context.

Utilization of geothermal waste as a silica adsorbent for biodiesel purification

S. Silviana,Didi Dwi Anggoro,Cantika Aulia Salsabila,Kevin Aprilio 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.10

The purification process of biodiesel requires an adsorbent to reduce glycerin content releasing high purity of biodiesel. The adsorbent must be affordable in source and process, readily available, and have high adsorption capacity. This paper discusses utilization of silica aerogel from geothermal waste as an adsorbent of biodiesel to reduce glycerin. The paper investigates the potential of a high silica content of geothermal waste as silica adsorbent by observation of the glycerin adsorption capacity and its kinetics study. At the beginning, geothermal silica preparation was subjected to the purification of geothermal silica waste using sulfuric acid, sol-gel process, and drying process at ambient pressure. This research was statistically carried out by varying the volume ratio of HCl to sodium silicate (3-5), drying time (1-2 hours), and percent weight of silica (3-5%-w) using Design-Expert® Version 8.0.6 (State-Ease, Inc). The silica product was characterized through BET, FTIR, XRF, and XRD analysis. Analysis of untreated and treated biodiesel used GPC, GCMS, and titration based on Indonesian National Standard (SNI) of No. 06-1564-1995. The optimum conditions for preparation for removing glycerin in biodiesel was reached at ratio volume of HCl to sodium silicate of 3 : 1, 2 hours of drying time, and 3%-w silica adsorbent. The optimum of surface area of the s ilica adsorbent and the glycerin adsorption capacity can be attained at 371m2/g glycerin and 10±0.1 mg/g, respectively. Further meaning, the glycerin concentration in biodiesel can be reduced from (4±0.10)% to (0.1±0.01)% by using the silica adsorbent performing biodiesel characterization according to SNI in terms of glycerin content. The second-order pseudo model can be used to describe the glycerin adsorption in biodiesel by determination of k at 0.0036 g/mg min at the optimum condition preparation.

주희영,정다희,노상현,이민희,Syifa Salsabila,임가영,이혜린,이초은,문주현,김규랑,이주영 한국생활환경학회 2022 한국생활환경학회지 Vol.29 No.2

The purpose of the present study was to investigate relationships between Wet-bulb globe temperature (WBGT), subjective perception and thermoregulatory behavior of residents in Seoul and Busan during summer. A total of 2,652 adults (1,327 in Seoul and 1,325 in Busan) participated in the six times of surveys with an identical questionnaire from June to August, 2021. WBGT was measured in Seoul and Busan six times on the same days as the survey conducted. WBGT was 28.3 ± 2.7oC in Seoul and 27.8 ± 2.4oC. Globe temperature was higher in Seoul than in Busan, while air humidity was higher in Busan than in Seoul. Residents in Seoul felt more thermally uncomfortable to temperature rise compared to residents in Busan. There was not a big difference in air temperature to be perceived as hot weather between residents in Seoul (30.4 ± 2.6oC) and in Busan (29.7 ± 2.5oC). Also, no differences in self-identified heat tolerance, clothing insulation in summer, and thermoregulatory behaviors to heat stress between residents in Seoul and Busan. In summary, the difference in the relationship between WBGT and thermal comfort which were measured on the WBGT-recorded days in Seoul and Busan indicated the difference between continental and marine climates, while no difference was found in thermoregulatory behavior or usual cognition to thermal environments between two cities. These results suggest that the impact of summer weather on human adaptation to heat was waned due to indoor air-conditioning systems in summer spread out in two cities.
