Urine and/or feces disposal systems are expected to replace the diapers currently used for urine and feces disposal for the elderly with urinal and/or fecal incontinence. The are designed to detect the urine and/or feces, cleanse the excremental body organs with water transported from a cleansing water container in the main body, suction them into a fluid waste storage container for future disposal, and dry the area with hot air supplied also from the main body. These systems thus could relieve the chores of a caregiver and could also enhance the patient's hygiene. We reviewed in this paper the detection systems of urine and feces, the main components of the urine and feces disposal systems, and tried to classify the systems currently available in the market.

Objectives : The purpose of this study is evaluating the effect of Hoelen Herbal-acupuncture (HO-HA) at $KI_{10}$(Umgok) on Lipopolysaccharide(LPS) induced nephritis in rats. Methods : The experimental rats were assigned to four groups; normal, LPS, saline, HO-HA groups. LPS(2 mg/kg) was administered to the rats in LPS, saline and HO-HA groups to induce acute inflammatory kidney damage. Saline injection and HO-HA were administered at $KI_{10}$ three times a week. Blood samples were taken from the rats for analysis of white blood cell(WBC), neutrophil, blood urea nitrogen(BUN), creatinine TNF-${\alpha}$, CINC-1. Urine samples were taken from the rats for analysis of urinal volume, creatinine and total protein. The kidney samples were taken from the rats for analysis of renal myeloperoxIdase(MPO). Results : HO-HA suppressed the increases of WBC and neutrophils in blood, BUN, creatinine, TNF-${\alpha}$ and CINC-1 in serum, and MPO in kidney of LPS-stimulated rats. In addition, HO-HA inhibited the decrease of urinary volume in LPS-stimulated rats. Conclusions : HO-HA has therapeutic effects on LPS-induced inflammatory kidney damage in rats. Further studies may be needed for clinical use of HO-HA.

Objectives: The purpose of this study was to investigate the effects of Zeae Stigma herbal-acupuncture (ZS-HA) at KI10 (Umgok) on nephritis induced by lipopolysaccharide (LPS) in rats. Methods: Rats were assigned to five groups, normal, LPS, NP, saline and ZS-HA. Rats in NP, saline, and ZS-HA groups were treated with needle prick, saline injection, and ZS-HA respectively at KI10, three times a week. All animals except the normal group were injected intra-peritoneally with LPS to induce nephritis. RBC and WBC, neutrophils in blood, TNF-alpha, CINC-1, creatinine in serum, urinal volume, total protein and creatinine in urine, and renal MPO were analyzed. Results: Needle prick at KI10 significantly reduced WBC in blood and CINC-1 in serum of LPS-stimulated rats. Saline injection at KI10 significantly reduced TNF-${\alpha}$ in serum and total protein in urine of LPS-stimulated rats. ZS-HA at KI10 significantly increased RBC in blood, and significantly reduced neutrophils in blood, TNF-${\alpha}$ in serum, and total protein in urine of LPS-stimulated rats. Conclusions: According to these results, it is postulated that ZS-HA at KI10 has anti-inflammatory and renal-protective effects on LPS-induced nephritis in rats, and both acupoint KI10 and herb Zeae Stigma made contributions to this effect. Further studies on the interaction between acupoint KI10 and herb Zeae Stigma may be needed.

Scales generated inside pipes cause negative effects on heat transfer performance, pressure loss and flow rate due to increased thermal resistance and reduced flow cross-sectional area. If these scales are not prevented or eliminated, thermal-fluid performance of the facilities can be deteriorated, or in extreme cases, accidents such as explosion due to overheating can occur. There are two ways to remove the scales, physically and chemically. Removing the scales physically needs specific machines which are expensive, and removing them chemically may provoke corrosion or shorten the age of the facilities. In this study, an eco-friendly pipe scale cleaner using natural organic acid is developed by applying the concept of a limestone cave generation. The manufactured scale cleaner is applied to remove the scales in industrial, water heating and urinal pipes. The results show that this cleaner removes scales more effectively and safely compared to existing scale treatments. Scale removal efficiencies of this work is 1.2~10.7 times for industrial pipes and 1.8~15.5 times for boiler water heating pipes higher than those of conventional cleaners.
