This study is to understand the actual condition of design and material of peanut-shaped diaper with looking at the types and characteristics of baby cloth diapers and domestic peanut-shaped diapers registered in the Patent Office. Furthermore, it is to suggest the basic data for designing more functional and comfortable cloth diapers. Here are the research result on the actual condition of design and material of baby cloth diapers. Firstly, 11 cloth diapers registered in the Patent Office can be divided into panty-shaped and straight line-shaped diapers. There are 7 kinds of panty-shaped cloth diapers which satisfy both the convenience of a disposable diaper and sanitation of a cloth diaper, and 4 kinds of straight line-shaped cloth diapers that minimize the weaknesses of existing cloth diapers. Secondly, domestic peanut-shaped cloth diapers can be divided into peanut-shaped, inserted, winged, velcro-attached diapers. Among 23 kinds of peanut-shaped cloth diapers from 16 companies, there are 12 kinds of peanut-shaped diapers which consist of layers of cloth to make peanut shape. There are 6 kinds of inserted diapers that insert extra diapers or handkerchiefs in between two sheets of cloth diapers and 3 kinds of winged diapers designed to shorten drying time with sawing only one side of several layered sheets. Also, there are 2 kinds of velcro-attached diapers that are removable according to the amount of excreta. Commonly used materials are cotton woven of diamond jacquard and knit of diamond Hole Stitch or Plain Stitch. And for handing the edge of diaper, the method of wrapping up the edge with cotton woven or knit bias is used.

The rate of disposable diaper usage has been increased continuously from convenience of disposable diapers and increment of women's entry in workforce. However, a new perspective toward disposable diapers has been come to the fore in various sides like babies' health, environment, and cost. Furthermore, cloth diaper has started to attract more attention. Since parents and grandparents pay more attention to children as birth rate dropped, they tend to purchase expensive goods if the quality or design of the goods is worthy enough. Therefore, this study has the purpose in presenting the basic data for developing functional and pleasant cloth diaper with analyzing the consuming patterns (convergence in nature, health and technology) and cloth diaper characteristics. The research on the actual condition about children cloth diapers and environmental-friendly materials is as follows. Firstly, as a result of analyzing pros and cons about disposable diapers and cloth diapers, the cloth diapers are estimated to have better health, environment, and cost factors than disposable diapers, only excluding convenience. Secondly, as a result of examining patent registered diapers, the disposable diapers have been improved from shape-centered development to well-being material development, and the cloth diapers have mainly developed functional shape-centered. Thirdly, as a result of analyzing children's goods made with environmental-friendly materials, the children's clothes already use organics and natural resources like beans, bamboo trees, ginkgo, and chitosan. Recently, the diaper industry starts to pay attention to environmental-friendly because the skin ailment from environmental pollution has been an issue. To conclude, children's cloth diaper should be appropriate to their body shape and optimized to have convenient form and functional materials. If environmental-friendly materials are used, quality, functionality, various demands from customers and vitalization of goods industry will be all satisfied.

Used disposable diapers have been considered for a long time as a type of waste difficult to recycle and valorize due to their composite nature including plastic, cellulose pulp, a super absorbent polymer and either urine, feces or both. Therefore, the fate of disposed diapers often is either incineration or landfill burial which both have various adverse environmental impacts. However, used disposable diapers contain nutrients: cellulose is an organic matter while urine and feces contain non negligible amounts of nitrogen, phosphorus and potassium which are primary nutrients included in most chemical fertilizers used in agriculture. In a scope of waste recycling and valorization, this study focuses on developing a method to achieve nutrient solution extraction from used disposable diapers. The experiment essentially consists in shredding the diapers and letting them macerate in solutions of sodium hydroxide with various concentrations to allow breaking down of the cellulose and super absorbent polymer and release of urine and feces before sterilizing the solutions in an autoclave to remove potential coliform bacteria. At the end of the experiment, a set of parameters is measured for the final solution to identify concentrations of nutrients as well as presence or absence of harmful substances. Results are discussed and directions for future studies are suggested, which include mechanization of the diapers shredding process or added aeration to enhance nitrification and absorption of extracted nutrients from plants.

This article is a continuing report about a development of disposable diapers for the elderly in need. In previous report, the first prototypes of disposable diapers in two different categories have been developed. One was a panty type and the other was a pad type. These prototypes were results of property test and wear test of existing disposable diapers in each categories. Yet, in order to develop useable products, the second property and wear tests using the first prototype diapers were carried out. Considering the resets of the second tests, enhancements to the first prototypes were made to refine the second prototypes. The panty type diaper were altered to be longer to prevent evacuation from leaking and fit better. The pad type diapers were altered to reduce thickness for comfort and wearing appearance when get dressed. Ultimately a lot more disposable diapers will be required in future. Resulting suggestions are as follows. Anthropometric data around hip area of elderly in both sexes have to be collected to give meaningful information to diaper manufacturers, so that they can manufacture for different sizes and different sexes. Also we suggests that diapers for specific disease such as diabetics have to be designed accordingly.

The peanut-shaped cloth diaper has cut uncomfortable crotch region off the square-shaped cloth diaper into a peanut-shape, and finished the edge by bias with multi-layers of fabric. This study has the purpose on providing the basic data for designing the peanut-shaped cloth diaper. For this purpose, the peanut-shaped cloth diapers on market were collected and analyzed by their shape and size, and also the patterns and differences in making were compared. 26 products from 17 brands were collected as samples. The analysis factors are the shape and size of the peanut-shaped cloth diaper, and characteristics and patterns in making. Among the samples, only 3 diapers were straight-shaped; the rest of them were peanut-shaped. The size difference between the big and small peanut-shaped cloth diapers was very large; the total length of the small one was 36.5cm-39cm which was very common, and the total length of the big one was more than 44cm. All diapers had longer width in the back than the front. The width of the front and back was different for each sample, therefore, it seemed to have some difficulties to set the standard. The peanut-shaped cloth diaper had different make-up depending on its characteristics including. absorbance, washing and drying. It was usually made by cotton woven of diamond jacquard or knit, and finished the edge by woven bias or knit bias. The peanut-shaped cloth diapers were various including a sheet of diaper, two sheets of diapers fixed with velcro, three sheets of diapers, and etc. For the patterns of the diapers, only two samples out of all had three dimensional shape, and the rest were produced using flat shape. There were no distinction between the diapers of girls and boys. Therefore, it is necessary to make the product based on scientific data about the peanut-shaped cloth diaper.

Diaper dermatitis, or commonly called 'diaper rash', is among the most prevalent cutaneous disorders of infancy and early childhood and important issue in nursing. The term itself is not diagnostic since it encompasses a variety of acute inflammatory reactions which are best regarded as a family of disorders arising from a combination of factors specifically attributable to the use of diapers Intensive study of the rash Process has shown that skin wetness and fecal enzyme activity are damaging to skin and lead to the development of diaper rash. This suggests that it is important to keep urine away from babies' skin, so that the skin remains as dry as Possible and maintains its barrier function abilities. Controlling the urine will also minimize the mixing of urine and feces within the diaper. which helps prevent the increased activity of enzymes that attack the skin and cause irritation. Therefore, a diaper that keeps the skin drier and limits the mixing of urine and feces will help Prevent the conditions that lead to diaper rash. Since their introduction about 35 years ago, disposable baby diapers have undergone many design and performance changes. In Particular. the Performance of diapers was advanced by the introduction of absorbent gel materials (AGMs) to Provide advantages in skin care. dryness, and leakage Protection Especially, important was the introduction of AGM which increased the absorbent capacity of the diaper several fold and Yielded marked reductions in the degree of skin hydration occurring under the diaper Studies show not only drier skin but more stable skin pH and less dermatitis with AGM diapers than with home-laundered cloth diapers or single-use diapers without AGM Minimizing diaper area skin wetness is important for managing and Preventing diaper rash. To minimize wetness, parents should use super absorbent diapers.

Purpose: This study was aimed to describe older adults' experiences of living with urinary incontinence and using diapers for its management in long-term care facilities. Methods: Qualitative data were collected through in-depth interviews with 22 participants in long-term care facilities. Content analysis was used to analyze the data. Results: Three themes and six categories were emerged. Participants navigated through those three categories as stages, including the initial stage of confronting the unacceptable reality, transitional stage of physical and emotional suffering, and adaptive stage of accepting the diaper usage as a part of life and hoping improvement. Six categories were feeling terrible with unavoidable use of diapers, being frustrated by nursing staff shortage and unsatisfactory care for urinary incontinence, physical discomfort from of wearing diapers and remaining unchanged, emotional difficulties due to using diapers, accepting and adapting to diaper usage as a part of life, hope for gender-specific quality care for urinary incontinence. Conclusion: The findings suggest that using diapers should not be mandatory to manage older adults' urinary incontinence in long-term care facilities. It is also critical to establish policies to address issues of nursing shortage and financial support for qualitative care to manage urinary incontinence in long-term care settings.

The analytical method of toxic heavy metals in disposable diapers was developed. Disposable diapers obtained from Korea, Japan, America and German were determinated and quantified. Sample treatment (Total Digestion) was wet chemical acid digestion for extraction of nine hazardous inorganic elements (Sb, As, Pb, Cd, Cr, Co, Cu, Ni, Hg) in disposable diapers. Inductively Coupled Plasma Mass Spectrometer (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) have been used for analyzing nine hazardous inorganic elements. The results were as follows : The concentration of extractable Sb which was treated for 3 hours with artificial urine and disposable diapers was higher than those of 6 hours and 24 hours. The concentration of extractable Cr was same as Sb. On the other hands, the behavior of Cu and Ni were different from Sb and Cr. Concentrations of extractable Cu and Ni increased as increasing the reaction time between artificial urine and disposable diapers.

The purpose of this study was to develop disposable diapers for the elderly in need by experimenting with wearing disposable diapers and analyzing the properties of materials of these diapers. The diapers were of two different types: one was a panty type for the elderly who were bed ridden, and the other was a pad type for the elderly who had incontinence. The subjects for the wearing test of the panty type were forty who were bed ridden, and there were forty subjects for the wearing test of the pad type who had incontinence. The disposable diapers for these experiments were chosen from those already found in the market place. Four panty types and three pad types were selected. From these experiments for the disposable diapers, the first prototypes were developed, and the second prototypes were proposed by experimenting with the first prototypes. The first panty prototype was designed to improve absorbing power, and we added waist rubber bands to prevent evacuation from back leaking and a frontal tape to prevent waistline film from tearing. The first pad prototype was designed to improve absorbing power also, and we added side rubber bands to prevent the side leaking and an adhesive tape on the fore part of the bottom to prevent the diapers from moving, and made the outline of the back area curved and thin to help hide the diaper from detection thus making the wearer feel better. From these test cases and analyzing the properties of materials with the first prototypes, we gained some success, but several points on further improvements were proposed to refine the final prototypes. The second panty prototype we proposed was to make 1he length longer, especially in the crotch area to prevent excess leaking and to fit the body more snugly. Also, the second pad prototype was proposed to reduce the total thickness of the diaper, and to improve the feeling and appearance.
