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.

Disposable diaper has been used in order to handle urine and feces conveniently. At present the amount of disposable diaper waste increases gradually. Incineration and landfill have been the only ways to dispose of disposable diapers. However, if they are disposed by landfill, decomposition will take more than one hundred years. In addition, another way of dispose incineration has caused air pollution. Therefore, it is necessary to study recycling process for disposable diaper since plastic and wood fibers of diaper are useful materials to recycle. In this study, pulping condition of disposable diaper waste was studied in order to effectively separate the components. Recovery rates of plastic and fibers were analyzed under different pulping conditions. It was found that optimum pulping consistency was 5%, time was 60 minutes, temperature was $50^{\circ}C$, and cut size is $21cm{\times}21cm$. The recovery rate of plastic and fibers can be achieved above 70% under the optimum pulping condition.

Objectives : To investigate minimum pressure by verifying changes in pressure due to bleeding amount during bloodletting-cupping therapy. Methods : (1) We compared adhesion performance of four different cupping cups of same size: two disposable cupping cups(A, B) and two reusable cupping cups(A, B) each were vacuumed three times and kept in place for 10 minutes. (2) We vacuumed two different sized disposable cupping cups(A), size.1(InnerDiameter 48.8 mm) and size.3(InnerDiameter 39.1 mm), twice each(-200 mmHg) on silicon plate. We injected water and air at regular intervals in cupping cups by using a syringe, and then measured change of pressure in cupping cups and pressure at the time of dropout. Results : (1) Pressure reduction was $4.75{\pm}2.78%$ on average in the order of 'Disposable[A]>reusable[B]>Disposable[B]>reusable[A]', so that pressure retention performance of disposable cups can't be regarded as inferior to that of reusable cups. (2) Pressure of disposable cupping B(size.1) decreased by an average of -40.08 mmHg per 5 ml of water. At -24.8 mmHg, when 22 ml of water has been injected, cup has come off. Pressure of disposable cupping B(size. 3) decreased by an average of -99.4 mmHg per 5 ml of water. At -48.6 mmHg, when 13 ml of water was injected, cupping came off. Conclusions : Considering reduction rate of pressure due to water injection, in case of bleeding more than 15 ml, size.3 cup always comes off, therefore it needs to be re-operated at least once. Meanwhile, size.1 cup does not always come off in the same condition, depending on the initial pressure and therefore, re-operation may be considered.

This experiment was carried out to develop the anesthetic methods for ultrasonography and a new simplified disposable needle guidance device for ovum pick-up(OPU) in cows. Three different anesthetic methods were applied as. 1) epidural analgesia only with 2% lidocaine(20~30 ml), 2) epidural analgesia with 2% under general sedation with xylazine, 3) epidural analgesia with 2% lidocaine under general sedation with detomidine. We evaluated the anesthetic effects with items such as relaxation of anal sphincter, tail movement and rectal wall, retractability of both ovaries, additional anesthesia and possibility of OPU. Through this experiment, the above three anesthetic methods were applicable to OPU, but the epidural anlagesia under general sedation with detomldine was most effective for OPU. We developed a new disposable needle guidance device with stainless steel tube. With this, disposable needles can be easily attatchable to any other intravaginal probes. And also, it was found to he practical, economic and effective for OPU with the recovery rate of 51.2%.

Purpose: This study was to explore the perception about menstruation and discomforts of using disposable menstrual pads in menstruating women. Method: A survey was conducted of 132 menstrual women recruited by convenience sampling. Data were collected by a face-to-face interview and a study questionnaire, and analyzed by frequency and $X^2$-test. Result: More than half of the subjects expressed a negative perception about menstruation, while 25% expressed a mixed perception and 24.2% expressed a positive perception. Women who perceived their menstruation negatively had more menstrual pain than the others (p<.001). The most frequently experienced discomforts of using disposable pads were an unpleasant smell (18.9%), leakage (18.9%), and discomfort (16.6%). Adverse effects of using disposable pads were reported as an itching sense (23.1%). skin rash (20.2%), and skin irritation (10.6%). Alternate materials were reported with tampons, alternate washable pads, and maternity pads. Conclusion: The results indicate that disposable menstrual pads cause several discomforts and common adverse effects such as skin problems. To decrease these discomforts and relieve adverse effects, planned nursing education including women's personal hygiene methods and information about an alternate pad may be helpful.

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.

During experimental Eimeria infections in chickens, facilities are often contaminated by fecal oocysts known to be highly resistant to both chemical and enzymatic treatments. Thus, studies using experimental Eimeria infections have been limited due to the difficulty of complete elimination of residual oocysts from both cages and facilities. To overcome this limitation, simple, inexpensive, and disposable cages were constructed from cardboard boxes and tested during experimental Eimeria maxima infections. The cages were used in animal rooms with only a 1.7% evidence of coccidia contamination between adjacent cages. No significant differences in fecal oocyst output and body weight gain were noted between animals housed in disposable cages and animals housed in wire control cages. This cage design is a useful means for preventing oocyst contamination during experimental conditions, suggesting that this disposable cage design could be used for other avian infectious disease studies.

Arthroscopy is a surgical procedure orthopedic surgeons use to visualize, diagnose and treat problems inside a joint. In usual, since the arthroscopic surgery is more accurate and minimally invasive than through 'open' surgery, the surgery of knee, shoulder, and wrist using auto-shaver is increasing in recent. However, repetitive use of arthroscopic-shaver may induce the second infection, hence the disposable arthroscopic-shaver should be developed. In this paper, a unique power transmission mechanism using DC motor, gear trains, and link mechanism is proposed for disposable arthroscopic-shaver and some test results of tissue cutting are introduced.

This study was designed to measure the amount of formaldehyde in the disposable napkins of eighteen (18) different products. It was aimed to investigate the actual situation of the napkin 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 actual situation of consumption and the recognizability of the formaldehyde were investigated by questionnaire. in the survey, the subjects was 12~53 years old and lived in Seoul Kyoungki-city. The statistical methods used were simple frequency and chi-square. The results obtained from this study were as follows; 1) Among eighteen (18) different disposable napkins, all was found to have less amount of formaldehyde than the japanese regulation. 2) From the survey on the actual situation of consumption, most resondents (66.1%) experienced the dermaptological problem after using the disposable napkins. 3) The recognizability of formaldehede was very low. The recognizability on the harmfulness of formaldehyde was low too, which represented the consumers had least or no knowledge about the formaldehyde release problem.
