Hajj is a fundamental pillar of Islam that all Muslims must perform at least once in their lives. However, Umrah can be performed several times yearly, depending on people's abilities. Every year, Muslims from all over the world travel to Saudi Arabia to perform Hajj. Hajj and Umrah pilgrims face multiple issues due to the large volume of people at the same time and place during the event. Therefore, a system is needed to facilitate the people's smooth execution of Hajj and Umrah procedures. Multiple devices are already installed in Makkah, but it would be better to suggest the data architectures with the help of machine learning approaches. The proposed system analyzes the services provided to the pilgrims regarding gender, location, and foreign pilgrims. The proposed system addressed the research problem of analyzing the Hajj pilgrim dataset most effectively. In addition, Visualizations of the proposed method showed the system's performance using data architectures. Machine learning algorithms classify whether male pilgrims are more significant than female pilgrims. Several algorithms were proposed to classify the data, including logistic regression, Naive Bayes, K-nearest neighbors, decision trees, random forests, and XGBoost. The decision tree accuracy value was 62.83%, whereas K-nearest Neighbors had 62.86%; other classifiers have lower accuracy than these. The open-source dataset was analyzed using different data architectures to store the data, and then machine learning approaches were used to classify the dataset.

The purpose of this study was to develop a compression inner layer (CIL) that can be attached to dress shirts for men who have gynecomastia (male breast enlargement). For this, we developed shirts with CIL prototypes based on the functional, expressive, and aesthetic (FEA) consumer needs model. The user-centered design principle guided the design process. Based on size measurements, in-depth interviews, and an online survey, the design requirements for dress shirts with a CIL were determined, and the prototype was developed. The dress shirts were constructed of polyester and spandex mixed materials, while the CIL was made of thin mesh fabric knitted from 80% polyester and 20% spandex. A CIL prototype was developed with a front zipper fastening to hold the upper body tight and compress the breast area. The CIL was attached by connecting a strap with snap buttons to loops sewn into the shoulder line of the dress shirt. In the trial and sensory test, the prototype helped breast size decrease while meeting target consumer needs. The outcomes of this study provide necessary insights to develop garments for gynecomastia patients.

An apatite drain was constructed on September 30, 1994 at the Green Valley Abandoned Coal Mine site near Terre Haute in west central Indiana. The primary objective of this experiment is to evaluate the long-term ability of the apatite drain to mitigate acid mine drainage (AMD) under field conditions. The drain 9 m long, 3.3 m wide, and 0.75 m deep, contain 95 rum to No. 30 mesh-size apatite ore (francolite) and receive AMD seepage from reclaimed gob piles, and designed according to the laboratory testing. The apatite drain was covered with limestone riprap and filter fabric to protect the drainage system from stormwater and siltation. The drain consists of about 50 metric tons of apatite ore obtained from a phosphate mine in Florida. A gabion structure was constructed downstream of the apatite drain to create a settling pond to collect precipitates. Apatite effectively removed iron up to 4,200 mg/l, aluminum up to 830 mg/l and sulfate up to 13,430 mg/l. The pH was nearly constant for the influent and effluent, ranging between 3.1 and 4.3. Flow rate measured at the gabion structure ranged from 3 to 4.5 l/m. Precipitates of iron and aluminum phosphate (yellow and white suspendid solids) continued to accumulate in the settling pond.

The recent trend in younger generations of wearing traditional costumes or incorporating fusion hanbok into daily wear necessitates the development of modern hair accessories to complement hanbok. The purpose of this study is to develop practical and modern hair accessory designs inspired by royal women's hair ornaments that complement hanbok, and therefore expand the scope of fashion content development utilizing hanbok culture as well as meeting the demand for various experiences of traditional culture. This research studied the literature on traditional hairstyles and accessories of Queen Yeong and constructed models of these accessories for the purpose of empirical research. The production process first required creating a basic foundation of nylon mesh reflecting the silhouette of a traditional hairstyle, and then grafting a digital textile printed fabric using majestic and extravagant royal relics on top, thus employing the trompe l'oeil technique to ultimately give the impression of wearing traditional jewelry. As a result, a total of six hair accessory designs were completed, produced with hairbands, hair pins, and hair ties. In addition, the accessories are designed to be easily worn regardless of the wearer's hair style, and the stiff yet flexible nylon mesh effectively expresses the shape of a voluminous hairstyle and creates an optical illusion, blending into the hair. These research results present a unique aesthetic and cultural experience to the greater public seeking both daily entertainment and value from rarity.

The purpose of this study was to provide a formative charateristics by analyzing aesthetic charateristics of Egypt costume expressed in contemporary fashion. The result of this study obtained through this process were as follows. Aesthetic characteristics were expressed as a primative-retro characteristics, and a erotic-retro characteristics and a decorative-retro characteristics. Based on these trends, this study analyzed formative charateristics in an aspect of form, color, material, and decoration. In the modern fashion, unlike the H-line silhouette given by a natural fit in the primitive retro, the erotic retro was characterized in the shape by a tight H-line silhouette. For the color, peach, yellow green, gold, light blue, red, and black were used as the main color. For the material, see-through, gauze, mesh, organdy, and tight vinyl were utilized to emphasize an erotic image and expose a body secretly. For the decoration, the characteristic of erotic retro using the simple or same colors frequently was the use of similar accessories colors matched with material colors. The decorative retro was characterized in the shape by a H-line silhouette connected as a part of clothing which applied passium and a greatly modified silhouette from an Egyptian simple style which was well-matched with splendid accessories. For the color, the broadest range of color changes was found from light pastel such as white, yellow, light pink, burnt orange, blue, purple, silver, gold, and red to strong vivid tones. For the material, modern materials such as organdy, tulle, leather, and furs were often used. For the decoration, passium, an eagle pattern, scarab earrings, a crown, a sneak-shaped coronet, and pictograph printed on the fabric were frequently used.

The lumbar disc is one of the first parts of the human body to age. Female discs start to age at twenty and completely age between fifty and sixty. The number of lumbar herniated intervertebral disc patients is increasing rapidly; however, studies on protective inner wear are insufficient. This study develops protective inner wear equipment for bodies. The following were the study methods and procedures. First, the protective design, pattern and making of the inner wear were based on the analysis of collected data. Second, one subject was selected, then human body parts were measured to create the inner protective pattern. The inner pattern was made by the basic size of the subject. The inner protective equipment was made for lumbar disc disease patients after a wearing test and after correcting the pattern. Third, inner protective equipment was thoroughly tested to verify the compatibility of lumbar pads. The following were the study results and observations. First, lumbar pads who had inner protection were easily worn and the design was very ladyish in contrast to other lumbar pads on the market. Second, the pattern was completed by referring to, Lee Hyoung Sook's, torso and her lumbar pad shape. The fabric was mesh (for good ventilation) and poly spandex (for elasticity). Third, lumbar inner protective equipment was verified through a subject assessment and a major assessment. This study showed high scores on appearance and functional satisfaction versus existing disc lumbar pads in the market. This study predicts that new waist protective inner wear can help the female patient's health and social life because it has great functionality and can maintain outer line patterns.

This study identifies consumer needs and a pattern sensory evaluation of jacquard fabrics for raincoats using quick-drying-absorbing polyester. We investigate the consumer's consciousness and raincoat improvements. Twelve kinds of jacquard fabrics were developed for use in this study. Developed jacquard fabrics were assessed subjectively by 152 university students using a 7-point scale of 26 consumer needs and 31 pattern image sensory descriptors. Data were analyzed by SPSS. The major results were: There was a need for consumers to improve the front fastener type, cuff fastener, mesh patch position, and raincoat pocket position. The most important parameter to choose raincoat fabric was waterproof and the other parameters were vapor-porous/water repellent, design, color, fashionability, air-permeability and easy-put on/off. The pattern image sensibility of jacquard fabrics was explained by seven factors: gorgeous, simple, cute, futuristic, ethnic, feminine, and cool. A higher pattern preference was found in the jacquard fabrics of unique, sporty, natural, luxurious, and trendy images. The pattern preference was predicted at 45.3% with gorgeous, simple, pure, cute, futuristic factors. The correlation coefficient between the pattern image sensibility factor 1 (gorgeous) and pattern preference was 0.674 and with factor 3 (cute) was 0.416, and with factor 6 (cool) was 0.209. The 4 factors (gorgeous, simple, cute, futuristic) were selected as a significant pattern image sensibility that influenced preference.

This research developed a smart girdle for adult women in their 20's that has an inserted carbon weaving heater to help with relief from coldness and abdominal disease through the thermal insulation effect. A pocket of powernet fabric was attached to the inside of the girdle for the easy insertion and separation of the heating device, while the heating device was fixed to a mesh material by cotton yarn and was wrapped with elastic lining material to prevent the mechanical devices from being exposed. A set of 3 hooks was attached to the center of the back of the heating device in consideration of convenience and mobility. Whereas the switch was inserted into around the right waistband, and the battery into the inner pocket around the waist, to integrate the heating device with the girdle. The satisfaction and usability of the fabricated smart girdle was verified by having research participants wear it to evaluate the appearance change caused by the device, the inconvenience of wearing/unwearing, mobility, and the satisfactory functionality of the device. As a result, the grand mean was evaluated to be high, with appearance (4.19), mobility (4.17), and functionality (4.51) being higher than 4.00; which indicates that the heat generation function of the smart girdle is effective. It may be said that such collection and analysis of data that reflect users' opinions have value and significance in that they can be grafted onto future research on new technology as well as they contribute to taking a step forward in the rapidly increasing research of smart clothing, with the new-type clothing equipped with new function.

In spite of simple and cheap cultivation method, water broadcast-seeded rice demonstrates uneven and unstable seedling establishment per unit land area and requires more herbicide and labor-input for weed control. Three experiments were conducted in a phytotron at 18$^{\circ}C$ to evaluate the adaptability of seed-mat mulching cultivation technologies in water seeded rice for the uniform seedling establishment and the inhibition of weed occurrence without herbicide application. Five different kinds of mat with different mesh sizes and fabric properties were tested. The emergence of rice was the highest in Lawn-mat treatment, being comparable with the control, in which seeds were sown without mat. The Lawn-mat also exhibited the lowest mat tension. Mat tension may influence the emergence of rice. And once it was soaked in water, it didn't maintain its original shape any more. The emergence rate of rice was the lowest in Safer-mat treatment. In Lawn-mat treatment, which was the most effective for rice emergence in the first study, the differences of emergence and seedling establishment of rice depending on the seeding position (upper, beneath, and between mats) treatments were negligible, while they were higher in dry seeds than in pre-germinated seeds treatment. The emergence as affected by the kinds of mat also showed the same trend when tested using barnyard grass. Depending on the kinds of mat, the inhibition effect of weeds was the greatest in Safer-mat and the poorest in Lawn-mat. These results strongly suggest the possibility that the uniform seedling establishment and weed management without chemical could be achieved simultaneously by seed-mat mulching through the combination of effective mat for the emergence of rice and another efficient mat for the inhibition of weed occurrence. This possibility was also tested in the field.
