Abstract: 

Small and Medium Enterprises (SMEs) face significant challenges in the global competitive market. An approach SMEs adopt to meet these challenges is implementing lean principles through the framework of lean implementation. Although some lean implementation frameworks have been introduced, previous research indicates that SMEs often need assistance applying this framework. This is caused by the need to adjust the lean implementation framework, which is considered limited by the resources owned by SMEs. Therefore, further research discusses adjusting the lean implementation framework and SME resources needed to improve operational performance. This study emphasizes the need for a lean implementation framework tailored to SMEs' scale and resources to reduce waste and improve operational efficiency. The lean implementation framework is developed by combining the lean implementation framework with the plan do check act (PDCA) approach and simulation to produce continuous improvements. The framework development stage evaluates the existing lean implementation framework based on previous research and SME resources. Furthermore, the framework that has been evaluated is grouped based on the plan, do, check, and action stages. This activity is carried out to ensure that lean implementation activities are a continuous improvement cycle. The final stage is adding simulation steps to the do and check stages to evaluate proposed improvements. The proposed framework was tested through a case study at Batik SME. The results showed the benefits and effectiveness of the proposed framework in the form of a 12.9-day reduction during work completion and an increase of 18.3% in the operator's utility.

Abstract: 

Aims: Tuberculosis is a chronic bacterial disease. This study aimed to identify the empowerment model of batik home industry workers in tuberculosis elimination that can serve as input regarding the empowerment model for the home industry workforce. Participants & Methods: This mixed-methods research employed a sequential exploratory approach. Data were collected through observation, questionnaires, snowball sampling interviews, and focus group discussions. The sample consisted of 99 batik home industry workers, selected using simple random sampling. Findings: Social capital and health belief model constructs are important factors influencing workers’ willingness to engage in efforts to prevent and control tuberculosis. Social capital had a positive and significant effect on perceived benefits and adherence to medication. Additionally, data revealed that 92 participants (92.03%) held negative perceptions of tuberculosis patients, which influenced their willingness to take tuberculosis prevention measures. Conclusion: A high level of seriousness regarding the TB threat exists among workers; however, they have a low perception of the benefits of TB prevention and a significant perception of barriers.

Abstract: 

ABSTRACT: In this work, hybrid fly ash geopolymer / alginate spheres (GSA) were produced and used as an effective and economical adsorbent in a treatment of batik wastewater. A preparation of GSA adsorbent involved a facile method where the fly ash (FA) based geopolymer was entrapped into sodium alginate (SA) followed by crosslinking of Ca2+ and SA. In additional to that, natural egg white was utilized as a foaming agent. Characterization of the GSA adsorbent strongly confirmed the formation of hybrid spheres that composed of geopolymer and alginate with extremely porous microstructure with porosity of 87. 64%. Surface area, average pore diameter and pore volume was 12. 874 m2 g-1, 3. 3110 nm and 0. 1684 cm 3g, respectively. Prior to the adsorption process, the batik wastewater was pre-treated using high concentration acid hydrofluoric (HF) and magnesium oxide (MgO). The optimum acidification pre-treatment at pH=3 removed ~ 93% of chemical oxygen demand (COD). In the subsequent stage, the highest percentage of COD removal was ~27% by utilizing 1500 mg L-1 f MgO powder. In the final stage, different dosages of GSA adsorbent was used in order to treat the remaining COD and resulted in as maximum as ~67% of the COD removal. According to the finding, the sequential pre-treatment and application of high-porosity hybrid GSA adsorbent offered a great potential to be implemented as an economical and effective batik wastewater treatment.

Abstract: 

Background: Azo is a synthetic dye used in batik industries. It can be toxic to the tissue when exposed via inhalation, swallowing, or direct contact. Expression of cytokeratin will change in hyperplastic and cancer of the oral mucosa. Expression of Cytokeratin 8, 18, 19 is strong in the epithelial cells that undergo excessive hyperproliferation and oral mucosal changes in leukoplakia and squamous stratification carcinoma. The present study was conducted to analyze the expression of Cytokeratin 19 in the epithelial cells of azoexposed buccal mucosa. Methods: A total of 30 males were divided into 2 groups of azo-exposed and controls equally. Criterion for azo-exposed participants was working at batik coloring division for at least 5 years, while the controls were the ones who were not exposed to azo dyes. Exfoliative cytology using cytobrush was the method of collecting buccal mucosal epithelial cells. Expression of Cytokeratin 19 was analyzed using Cytokeratin 19 monoclonal antibody and immunohistochemical staining. Data were analyzed using independent samples t test in SPSS 13. 0 software. Results: There was a negative expression on the controls, while positive expression was observed in the exposed group. T test analysis showed significant differences (p<0. 001) in the positive expression of the exposed group (97. 600± 2. 063) compared to controls (3. 133± 1. 641). Conclusion: Azo dye could increase the expression of Cytokeratin 19 on buccal mucosa epithelial cells.

Abstract: 

Introduction: In this work, a flexible, and wearable point-of-care (POC) device integrated on a pain relief patch as wearable colorimetric sensors have been developed for sweat analysis, such as lactic acid, sodium ions, and pH simultaneously. Herein, the patch has stilfunctioned as pain relief, while it allows for sweat monitoring during exercise, and in daily activities. Methods: It was constructed on cotton cloth using wax printing technology (batik stamp) as cloth-based microfluidic devices (CMDs). Here, it uses micro volumes of samples to perform the reaction in the sensing zones, where the sensitive reagents are immobilized so that it can collect and analyze the sweat (lactic acid, sodium ions, and pH) as the model for sweat analytes. The colorimetric analysis was conducted via a smartphone camera by using a free app (Color Grab) for a color image analysis that uses for quantitative analysis or naked eye for semi-qualitative analysis. Results: The ∆, RGB value of the CMDS shows the excellent linear correlation vs analytes concentration, where the coefficient of correlations was found for lactic acid (R 2 = 0. 994), sodium ion (R 2 = 0. 998), and pH (R 2 = 0. 994). The ∆, RGB value shows the appropriate color value for the linear correlation of the analyte target concentrations in the sweat samples. Here, the limit of detection (LOD) was found at 45. 73 µ, g/mL for lactic acid and 56. 46 µ, g/mL for sodium ions. The reproducibility was found at 0. 79% and 0. 89%, for lactic acid and sodium ions respectively. Conclusion: It was applied for sweat analysis during exercise, and the results show in agreement with the standard methods used in a clinical laboratory.

Abstract: 

Manual printing is considered one of the common techniques in the reproduction of art, in which the intervention of the human factor is very high And most of its executive steps, such as design, preparation of printing media, printing and the operations after that, are done by hand. In manual printing, there is usually no customer, and it can be said that the result of the work is considered the final product. By printing and duplicating work, the artist can make cheaper examples available to those interested. Its different methods include hollow printing, embossed printing, level printing, silk printing, batik printing, etc. In this type of art, images are created indirectly and its methods are suitable for expressing the new and creative experience of the artist. The origin of hand printing in the world is related to the effect of hands stained with soot on the walls of stone ancient caves. Its first manifestations in Iran have appeared in the motifs of seals. The term used in Iran for basme with a wooden mold, has a long history. But what we know as Eidisazi was a type of traditional hand printing in the Qajar era In which the artist would carve some decorative wooden molds with different subjects on paper and then paint the resulting images with ink or watercolor. These pictures were bought by Mullahs and Mullahbajis and were given as gifts to school students near Nowruz. Usually, the number of motifs and pictures of each print represented the academic years of the student receiving the gift. This art dates back to the end of the 12th century of Hijri and maybe older, but with the introduction of machine printing in the 13th century of Hijri, this art is declining. There was a lot of variety in the motifs and images of the Eidisazi, but these motifs were different from each other in terms of quality and were not uniform in terms of theme. Perhaps the Eidisazi designs can be found in the motifs of pens, miniatures and oil paintings in the Zand and Qajar eras and religious curtains. The variety of motifs is such that you can see both goat and martial motifs, as well as religious and historical scenes and themes of everyday life. The Eidisazi pictures reflect the aesthetic appeal and taste of the people of the Qajar era. Unlike the official paintings of the court and nobility, which are rich and detailed, their obvious feature is considered. The lines in these prints are very simple and without complications or details. All in all, the patterns of Eidisazi are from the splendor of the nobility of the period, and the complexity of the designs has turned into simple patterns. What is beautiful and catchy at first sight in these images is their simplicity and harmlessness. This simplicity attracts attention not only when compared to the official and courtly art of that period, but it is also evident when compared to folk images (paintings of coffee houses, paintings on tiles, etc.). The narrative that exists in these forms is probably the result of the stories that are mentioned in coffee houses or gatherings of the messengers. Sometimes the design of the figures and objects do not have the correct proportion, but often the figures are expressive and represent the characters' bravery, oppression, anger and worries without any difficulty. The subjects of the images are often taken from folk stories such as Samak Ayyar, Amir Arslan, etc., or religious stories such as the martyrdom of Imam Hussein (a.s.), the story of Yusuf, etc., or mythological stories such as the stories of the Shahnameh or It is taken from everyday life and ordinary people without any stories or anecdotes. Eidisazi as a folk and traditional art that has been formed among the common people has never had a strong supporter. For this reason, our information about it is limited to the images obtained from the number of about 100 molds And unfortunately, most of them are damaged or without birth certificates and titles. The aim of this essay is to introduce as much and better as possible this traditional heritage and folk art, which is done with the approach of structural analysis and graphic dimensions of the motifs of these works. Following this goal, the main question of the research is raised as follows: What are the visual characteristics and visual space of the Eidisazi motifs? The history of research related to Eidisazi is summarized to the introduction of this type of printing, based on this, the present article also studies the structure of motifs and visual elements of Eidisazi based printing with a brief overview of previous achievements. The research method is descriptive-analytical, which is done by referring to documentary sources and viewing the images of these motifs. The statistical population is the number of more than 30 printed images of basmeh, which were obtained by referring to the above-mentioned records and the online gallery of the Children's Literature history Research Institute. The criteria for selecting the samples was based on the health of the remaining images and ease of access, and the works that had the greatest affinity in providing the goal and answering the research question were selected. The results of the research showed that as a type of traditional art, Eidisazi is a part of Iranian national identity and enduring heritage, whose visual values cannot be ignored despite its obsolescence. The motifs of Eidisazi are derived from the beliefs of the people of the era who gave importance to religious, literary, mythological themes and folk tales and displayed their thoughts in the form of simple and concise motifs. Eidsazi artist has tried to create the greatest impact on the audience with minimal facilities and has presented art that can be accessed and used by all classes and masses. Understanding the visual space of these motifs can play an important role in contemporary art, therefore, in order to answer the research question, the following achievements have been achieved. The free and informal nature of the Eidisazi motifs is rooted in its function, which can also be seen in the components and visual elements of the images. As the main element of the print structure, the line performs several tasks that have led to the creation of various visual effects on the viewer. The dominance of the line element is evident in the Eidisazi motifs and as the factor that separates the shapes from each other, it is also responsible for the lack of elements such as color. The lines of the design have found different expressive roles and have become the cause of darkness-brightness, texture, rhythm and patterning in these prints. The balanced connection of positive and negative levels, the creation of light shadows by linear stripes and black spots, the drawing and decorative texture and the varied rhythm of the lines have given a sense of dynamism and vitality to the images and served the performance and identity of non-courtly and popular art. The surface that is formed by the movement of the line in the space shows its most complete visual expression in Eidisazi when viewed from the front. In general, the surfaces in these motifs appear flat and two-dimensional. The predominance of non-geometric and free surfaces in the images of the prints have appeared in line with the informal and free nature of the themes. The motifs of Eidisazi have a balanced and often figurative composition, which are formed in a closed viewing angle, and its faces and figures have a general similarity; A similarity that is formed according to the aesthetics of the Qajar era and shows the type of coverings of the lifestyle of that period. As the dominant element of basmeh, human is generally located in the center or the most impressive point of the composition, and the way it is drawn emphasizes the power of design, animal bodies are designed in diverse and dynamic forms, and strange characters and imaginary creatures are also in these images. It can be seen that the figures of evil creatures are often drawn by exaggerating the dimensions of the head. The print artist has carved various forms of simple figures with brief lines. Figures that are influenced by the popular Qajar style are short and relatively fat. The soft curves of the lines in drawing the figures and the folds and creases of the clothes and decorations convey a sense of life and reduce the passivity of the spaces. This way of working contrasts with the official subjects of the court and depicts the dynamics of life and beliefs of ordinary people and their popular traditions.
