In this study, the effects of multi-complex agents addition on characteristics of electroless Ni plating solution are investigated. The species and the concentration of complexing agents are major factors to control the deposition rate, P concentration, and surface morphology of plating films. Adipic acid increases the deposition rate in regardless of single- or mutli-complex agent addition. However, lactic acid effectively increases the deposition rate in case of multi-addition as the complex agents with adipic or sodium succinate acid. In addition, sodium citric acid and malic acid show good stabilizing effects of plating solution and lowering the deposition rate, because they have high complexibility. Therefore, it is suggested that the development of Ni-P plating solution suitable for diverse usages can be carried out systematically using the database from this study.

This study analyzed the physical properties and flame retardancy of Tencel FR/Cotton complex knit fabrics in order to satisfy two aspects of eco-friendliness and functionality. The flame retardant (FR) treatment of complex knit fabrics was applied by a pad-dry-cure method for additional functionality. Tensile strength, extension, bursting strength, LOI, and flame retardancy were measured by the KS (Korean Standard) K manual. The hand value knit fabrics were measured by KES-FB system. Subsequently, tensile strength and extension of wale and tensile strength of course increased in tandem with the Tencel FR yarn content. Tencel FR/Cotton complex knit fabrics were suitable for summer-weight and for baby clothes through the KES-FB system measurements. The bursting strength of Tencel FR/Cotton complex knit fabrics decreased as the contents of the Tencel FR increased; in addition, LOI increased as the contents of Tencel FR increased. This was due to the Tencel FR flame resistance function; however, the tensile strength decreased. The optimum fiber content of Tencel FR/cotton content was 1:1. The optimum conditions of flame retardant treatment were a treatment temperature $130^{\circ}C$ and the concentration of finishing agent and assistance binder (AR4260) was 35% and 1%, respectively.

The purpose of this study was to investigate the effects of 8-week schroth 3-dimensional exercise and ball-sling complex exercise treatment on cobb's angle, abdominal muscle endurance, flexibility and balance in adolescents with idiopathic scoliosis. Thirty subjects with scoliosis were random assignment into one of two experimental groups, either schroth treatment(n=15) or ball-sling complex exercise treatment(n=15). Exercise program was to perform for 8-week and 90min and 3 times per week. The results of this study were as follows; First, cobb's angle was significantly decreased after 8-weeks in schroth treatment(p<.001). And also abdominal muscle endurance(p<.05), flexibility(p<.001) and balance(p<.001) were significantly improve in pre vs. post treatment. Second, the ratio of cobb's angle change was significantly higher in schroth treatment compared to ball-sling complex exercise treatment following 8-weeks(p<.05). These results suggest that although both the schroth treatment and bal-sling complex exercise treatment in adolescents with idiopathic scoliosis can improve on cobb's angle, abdominal muscle endurance, flexibility and balance, but schroth treatment was better than ball-sling complex exercise treatment improving effect of cobb's angle. Therefore, we consider that schroth treatment has more effect of prevention and therapy in idiopathic scoliosis in adolescents.

The aim of this study was to investigate the hepatoprotective effect of $ACTIValoe^{(R)}$ N-931 complex, a mixture of Aloe vera and Silybum marianum, against acute liver injuries. Acute liver damages were induced by intraperitoneal injection of galactosamine (GalN, 700 mg/kg), naphthylisothiocyanate (ANIT, 40 mg/kg) and ethionine (500 mg/kg). $ACTIValoe^{(R)}$ N-931 (85, 170 and 340) was administered orally 48 h, 24 h, 2 h before and 6 h after the injection of hepatotoxins. At 24 h after GalN treatment the levels of serum aminotransferases and hepatic lipid peroxidation were significantly elevated, whereas hepatic glutathione, serum triglyceride (TG) and total cholesterol were decreased. These changes were attenuated by $ACTIValoe^{(R)}$ N-931 complex. The serum aminotransferase activities and total bilirubin significantly increased at 48 h after ANIT treatment, but were attenuated by $ACTIValoe^{(R)}$ N-931 complex. The bile flow was lower after ANIT treatment, which was restored by $ACTIValoe^{(R)}$ N-931 complex. $ACTIValoe^{(R)}$ N-931 complex reduced the ethionine-induced elevated hepatic TG contents. Histopathological analysis revealed that signs of liver injury were prominent at 24 h as result of ethionine injection, demonstrated by extensive areas of fatty change and microvesicular steatosis were observed around cells. These changes were attenuated by $ACTIValoe^{(R)}$ N-931 complex. Our results suggest that the $ACTIValoe^{(R)}$ N-931 complex has a protective effect on acute liver injury.

In many countries in order to manage corrosion of water treatment process, it is currently using Langelier index (LI). However, management of the Larson's ratio (LR) to compare corrosion management and LI which can be generated by the water treatment process is required. In this study, in order to ensure data LR, factors associated with the actual corrosion resistance of water treatment plant was measured. Using the measured data, the model equation can be estimated alkalinity, and using the statutory water quality data, LR and alkalinity is estimated. At comparison of the measured value and estimated value of alkalinity, it appeared in $R^2$ = 0.629, using the statutory water quality data and estimated alkalinity model, LR and alkalinity (Whole water treatment plants : 472) is estimated. Concentration of estimated alkalinity is 0.5 mg/L to 107.5 mg/L (average : 23.2 mg/L), and LR is 0.1 to 10 (average : 1.3). At tendency to corrosion of investigated LR, "No metal tendency" (>0.5) is 39 water treatment plants, 8.26 %, and "corrosion metal tendency" is 433 water treatment plants, 91.74%.

The pathogen Mycobacterium avium complex (MAC) is the most common cause of nontuberculous mycobacterial pulmonary disease worldwide. The decision to initiate long-term antibiotic treatment is difficult for the physician due to inconsistent disease progression and adverse effects associated with the antibiotic treatment. The prognostic factors for the progression of MAC pulmonary disease are low body mass index, poor nutritional status, presence of cavitary lesion(s), extensive disease, and a positive acid-fast bacilli smear. A regimen consisting of macrolides (clarithromycin or azithromycin) with rifampin and ethambutol has been recommended; this regimen significantly improves the treatment of MAC pulmonary disease and should be maintained for at least 12 months after negative sputum culture conversion. However, the rates of default and disease recurrence after treatment completion are still high. Moreover, treatment failure or macrolide resistance can occur, although in some refractory cases, surgical lung resection can improve treatment outcomes. However, surgical resection should be carefully performed in a well-equipped center and be based on a rigorous risk-benefit analysis in a multidisciplinary setting. New therapies, including clofazimine, inhaled amikacin, and bedaquiline, have shown promising results for the treatment of MAC pulmonary disease, especially in patients with treatment failure or macrolide-resistant MAC pulmonary disease. However, further evidence of the efficacy and safety of these new treatment regimens is needed. Also, a new consensus is needed for treatment outcome definitions as widespread use of these definitions could increase the quality of evidence for the treatment of MAC pulmonary disease.

Objective : To use and its affecting factors of patients' outpatient treatment that have single and multiple chronic illnesses Method : We used the 2011 study by the Ministry of Health and Welfare, "Report on Usage and Consumption of Korean Medicine." This report was conducted on outpatients and inpatients that visited Korean traditional medicine, from August 25th, 2011, to September 30th, 2011. Our research was based on 1729 patients with chronic diseases aged 30 and over who received outpatient treatment during the last three months. Results : There were 1365 patients with non-complex chronic diseases, while there were 364 patients with complex chronis diseases. Patients had 1 - 8 chronic diseases, and the average number (standard deviation) was 1.26 (0.59). There were statistically significant differences by sex(P<0.0001), age(p=0.0045), marriage (p=0.0060), education level(p<0.0001), income level(P=0.0063), and types of health insurance(p=0.0023). The diseases most common among patients with non-complex chronic diseases were: low back pain, arthritis, gastrointestinal disorder, frozen shoulder, side effects from motor accidents, high blood pressure, fracture, stroke, diabetes, cancer, atopic dermatitis, and asthma. The diseases most common among patients with non-complex chronic diseases were: arthritis+low back pain, low back pain+gastrointestinal disorder, low back pain+side effects from motor accidents, low back pain+frozen shoulder, arthritis+gastrointestinal disease, gastrointestinal disease+frozen shoulder, arthritis+low back pain+gastrointestinal disease, high blood pressure+arthritis, arthritis+low back pain+frozen shoulder, arthritis+fracture, and arthritis+side effects from motor accidents. There were statistically significant differences among the usage of medical clinics by: frequently used clinic (p<0.0001), number of treatment (p<0.0001), the cost of outpatient treatment (p=0.0073), the satisfaction rate (p=0.0171), whether the clinic is the preferred clinic (p=0.0040). In model 1, men than women, people who had local benefits instead of type 1 medical aid, and patients with complex chronic diseases were more likely to use Korean medical clinics. In model 2, men than women, people who had local benefits than people with types 1 and 2 medical aids, people who went to pharmacies and Korean medicine pharmacies than people who went to hospitals, people who went to get treatment 1-10 times than people who visited 11-20 times and more than 41 times, and people who spent less than ten thousand Korean won than people who spent 1 to 2 million Korean won, and people without complex chronic diseases were more likely to use Korean medical treatment. Conclusion : There were differences in sociodemographic characteristics and the usage of medical clinics between patients with non-complex chronic diseases and patients with complex chronic diseases. Among patients with complex chronic diseases, women, patients with types 1 and 2 medical aid, patients who used Korean medical clinics, patients who were treated 11-20 times and more than 41 times, and patients who spent 1 million to 2 million Korean won on outpatient treatment used less treatment than patients with non-complex chronic diseases. However, patients with complex chronic diseases used pharmacies and Korean medicine pharmacies more.
