This study was designed to measure the amount of formaldehyde in the disposable diapers of seven different products. It was aimed to investigate the actual situation of the diaper consumption and to relate it to the amount of formaldehyde measured. The degree of recognizability on the harmfulness of formaldehyde was also studied. The amount of formaldehyde was measured by means of the Acetyl Acetone method. The a ual situation of consumption and the recognizability of the formaldehyde were investigated by questionnaire. In the survey, the subjects had their babies aged from 0$\~$3 years and lived in Seoul. The statistical methods used were simple frequency and chi-square. The results obtained from this study were as follows; 1) Among seven (7) different disposable diapers, two were found to have less amount of formaldehyde than the Japanese regulation. 2) From the survey on the actual situation of consumption most respondents ($53.7\%$) experienced the dermatological problem after using the disposable diapers. Actually for the diapers which had a lot of formaldehyde, the respondents experienced the problems more severely. 3) The recognizability of formaldehyde was very low. The recognizability on the harnfulness of formaldehyde was lower, which represented the consumers had least or no knowledge about the formaldehyde release problem.

This study was the designed to measure skin irritation caused by clothing at free foraldehde have caused a substantial number of cases of dermatitis type. Free formaldehyde levels were observed in infant's sanitatized goods9disposable diapers, cotton-diapers and under wear etc.) at 1992, 1994. The amount of free formaldehyde was measured by means of Acetyle Acetone method(KS K 0611). As the resort, underwear generally gave the highest free formaldehyde level, but disposable diapers and cotton diapers showed the lowest level. The formaldehyde level in intan's clothing lowered in 1994 than 1992, after the enforcement of the level in intant's clothing lowered in 1994 than 1992, after the enforcement of the formaldehyde level control. it was found that 38.7% of infant's sanitatized goods still exceeded th controlled level(A-Ao : 0.05) In the future, research to lower the amount of formaldehyde released form fabrics will also lead to decreased incidence of garment formaldehyde sensitivity. The possibility of a consumer suffering is being in convenienced form a textile-related skin problem will be even lower than it has been in the past.

This study analyzed and standardized the harmful substances of organic compounds(dioxins) in disposable diapers for infant's clothing. Commercial samples obtained from Korea, Japan, America and German were determined by HRGC/HRMS. Experimental Methods were consisted of comparision of extracting solvent, analysis of PCDD/Fs, and analysis of PCDD/Fs of extraction in disposable diaper. The results were as follows. No high TEQ values in TCDD(1), PCDD(0.5) and HxCDD(0.1) were found for commercial disposable diapers from country Korea, Japan, U.S.A and German. In extraction for 6hrs experiments, HpCDD and OCDD were detected in disposable diapers of U1, U2 and G2, respectively. In extraction fur 24hrs experiments, HpCDD, OCDD and OCDF were detected in disposable diapers of J3, U1, U2 and U3. So we need to set standards of measurement for harmful materials contained in textile goods. This will make a safe and comfortable clothing environment for all users, regardless of age.

A necessity for infants, diapers are not only used over long durations, but are also in direct contact to the infants' skin, making the choice of diaper to be of utmost importance. Current interest in cloth diapers is rapidly increasing because of issues concerning the baby's health, green environment, and economy. However, previous researches on cloth diapers are limited to simply investigating the form and material of commercial cloth diapers. There are few in-depth researches for the optimal cloth diaper development. This is therefore a fundamental research for the development of optimized cloth diapers, and analyzes the difference in absorption depending on the placement of seam line (liner, darts, and I pattern), the locations of liquid spraying (1 cm and 8 cm ahead of the center), and the amount of liquid capacity (10 and 20 ml). Currently, the development of diaper patterns considers the crotch shape of the infants and the skin length deformation. As a result, in the case of the I-pattern, the horizontal seam line prevents water from spreading to the front and back, thus reducing the absorbed area. This result was more clearly visible when water was sprayed at the center. The effect of the seam line became more obvious when there was more water (20 ml); also, when water was sprayed at the center, more leakage was observed. Using the results of this research, implementation of horizontal seam is expected to prevent the upward spread of urine.

Purpose : Urine collection using a sterile adhesive bag for urinalysis has been used commonly in infants and young children. However, this method has had some drawbacks. So, this study was performed to evaluate the usage of disposable diapers as a substitute for the routine urine collection method. Methods : 60 mL of self voided fresh urine was collected from 99 patients. Half of the urine was poured on the disposable diapers which did not contain absorbent gel beads. After 1 hr, we obtained the urine samples(extracted urine) by compressing the wet diapers using a 50 ml syringe. Routine, microscopic and biochemical analyses were performed on the other half of fresh urine and extracted urine. Then we compared each result by correlative analysis. Results : 198 samples from 99 patients were evaluated. The results of routine urinalysis except WBC and biochemical urinalysis showed a significant correlation between the two groups(P<0.05). The relative coefficients of urine SG, pH, glucose, protein, blood and leukocytes between the two groups were 0.964, 0.938, 0.977, 0.956, 0.931 and 0.738, respectively. Those of urinary sodium, potassium, chloride and creatinine were 0.997, 0.998, 0.995 and 0.998, respectively Microscopic examinations showed lower relative coefficients than the other results, 0.740 for RBC and 0.602 for WBC, but these were still significant(P<0.05). Conclusion : The results of the urine analysis with extracted urine from diapers correlates well with that of fresh urine. This new method is very helpful and can be used as an alternative of urine collection, especially for infants and young children. (J Korean Soc Pediatr Nephrol 2005;9:128-136)

Three different methods (simple washing of plastic and pulp sample, washing after direct heating of the diapers, and the heating after washing of plastic and pulp sample) were carried out to decrease total coliforms and heterotrophic plate count (HPC) in the diaper's plastic and pulp. Plastic and pulp samples were obtained from diaper by treatment with 10% $CaCl_2$ and 4% sea salt water, dilution with 1,000 ml tap water, and draining by using sieves. Three times washing was the most appropriate for the reduction of microorganisms in plastic and pulp. By three times washing, the number of total coliforms in the plastic and pulp samples showed 92.8% and 99.8% of decrease, respectively, and the number of HPC showed 97.3% of decrease in the plastic and 98.5% of decrease in the pulp. The washing after direct heating of the fecal contaminated diapers was not effective because HPC in the plastic and pulp samples were still detected about 2-3 log CFU/g in the plastic and 1-2 log CFU/g in the pulp, respectively, even after heating at $60^{\circ}C$, $80^{\circ}C$, $100^{\circ}C$ for 12 h. Meanwhile, total coliforms and HPC were completely sterilized at $80^{\circ}C$ for 4 h by heating after washing of plastic and pulp samples, suggesting that this method was the most appropriate method for the reduction of microorganisms in plastic and pulp obtained from fecal contaminated diapers.

This study was carried out to investigate the effect of changes in child care technology on mother-child contact by using all sorts of literature such as diaries, documents or statistical data. Child care technologies began to change during the 1960's. Diverse goods and services such as baby dry milk, paper diapers and child care centers have made child care easier and saved a great deal of time. This has also allowed women to participate in labor markets easily despite rearing children. But maternal contact with children have declined due to new goods and services and this trend is especially prevalent in early childhood. It could be supported that the convenience of rearing rather than the needs of children like as attachment to maternity primarily was considered in technological change. From this results it was suggested that we should develop the alternative child care technologies which better reflect children's needs.

Dyeing fastness and antibiosis effects of fabrics dyed with wormwood, which has been used in folk medicines and dietary life in Korea for a long time, were studied through dyeing small overcoats, which are used as diapers, with wormwood extract. As for the dying fastness test results, the fastness of decoloration was not that good but the pollution level showed a relatively positive result. As for the antibiosis effect results, the antibiosis of the dyed sample was better than the original sample on 3 kinds of bacteria, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and on 2 kinds of the fungi(Eumycetes). Aspergillus niger and Candida albicans. Especially, the sample that was mordant with CaCl2 and FeSO4·7H2O showed the best antibiosis effect. On the other hand, the sample that showed the best antibiosis effect was the refined fabric, which is a fabric that is not dyed.

This study is designed to facilitate the creation of home environment conducive to the family taking care of chronic bed-ridden patients with more effective method. The need for this study has emerged against the background of marked changes in the structure of ailments and causes of death, resulting in the number and plights of chronic bed-ridden patients as well as of a rapid increase in demand for medical care and resulting premature discharge. Keeping these in mind, this study focused on home-wards where the majority of chronic bed-ridden patients are being cared for. Despite. their overriding importance, home-words are less than efficient in caring (or chronic bed-ridden patients. These circumstances require the designing of home-wards that can offer greater comfort to patients and at the same time make things easier for caregivers, on the basis of an overall analysis of patients' life and home - ward situation. According1y this study adopted a Participant Observation Method derived cultural anthropology, Toward this end, 3 patients were chosen as subjects of this study for intensive interviewing and participant observation. In the process of this field re-search efforts were made to collect emprical data, that is, to faithfully record the words of the subjects and their caregivers for analysis and interpretation. The findings of these analyses are as follows. Firstly, the chronic bed-ridden patients are mostly being taken care by close family members. Secondly, a room for the exclusive use of the patient, floor, kitchen, bathroom and multipurpose space were found to be necessary for proper caring of the patient. These spaces were respectively used with a view to 1) accomodating the patient as well as caregivers' activities, 2) keeping general and medical supplies and other appliances for patient's care and drying the patient's washing, 3) preparing and keeping the patient's foods and beverages, 4) keeping the supplies necessary for cleaning the patient's body and treating the patient's eliminations, 5) washing the patient's clothes, underwears and bedclothes. The patient's room in turn is subdivided into six portions in terms of uses : specifically the places for accomodating 1) the patient, 2) medical supplies, 3) medicines, 4) linens St clothes, 5) bedclothes and, 6) diapers. Thirdly, the activities of the caregiver are subdivided into seven key areas : hygiene, exercise, diet, elimination, therapeutic nursing, prevention of sore, and other activities. Each area is further classified into several different activities of caring. These activities we mainly carried out in the patient's room. Fourthly, the supplies for caring the chronic bed-ridden patient is divided into two large domains : medical and general supplies. Finally, three main problems areas were found in this study on the part of caregivers, that is, sore prevention, hygiene problem related frequent urination / defecation, the caregiver's physical, psych ological and emotional burden. In consideration of the aforesaid problem areas, a model home-ward was developed in this study. The newly-developed model has been found to have the following six advantages. Firstly, the time and effort required for maintaining the patient's hygiene are reduced, thus relievins the caregiver's physical and psychological bur-den. Secondly, the patient's hygiene can be maintained in satisfactory conditions, because the patient's eliminations are more easily removed. Thirdly, skin irritations caused by the patient's eliminations were remarkably reduced and so were the patient's sores due to moisture and bacteria. Fourthly, the home-ward have a tilt-table ef-fect thanks to the inclining room floor. This improves the patient's cardiovascular function as well as constantly changes pressed skin areas and thus prevents sores. Fifthly, improved shelf arrangements help make the best use of patient's supplies. Sixthly, the trouble of continuously changing clothes, underwears, diapers & bedclothes is remarkably reduced simply by covering the patient with cotton sheets when laid in bed. This is espected to cut down expenses by reducing the comsumptions of diapers and other disposable supplies.
