The construction wastes have been enormously increased after 90's, but construction wastes have depended on reclamation, therefore the environmental disruption and contamination are getting in the hot issue of society and in controversy with residents. With the consequence that indicates a substitute about an application of construction waste units is the most important thing for studying construction wates of quantity when the construction units are demolished. Nowadays, the area under the housing environment amelioration policies is getting rapidly old, then it is beyond anticipating reconstruction. Likewise, it is common when the process of construction wastes make progress to investigate uneconomically in point of facts, therefore to derive economical effects using construction wastes units should be urgent as soon as possible. In conclusion, the purpose of this study offers the variety of construction wastes and process of treatments, comparison of which the construction is demolished and economical effects of application of construction units.

Ameliorating effects of dolomite and sludge on the polluted soil sampled from Ulsan and yeocheon Industrial Complexes were investigated. Ameliorating effects were analysed by changes of soil properties and plant growth after treatment of dolomite and sludge. Soil properties were investigated by analysing organic matter, N, P, K, Ca and Mg contents and pH. Growth of sample plants was investigated by leaf area calculated from length and breadth of leaves and by biomass from diameter and height of sample plants. Quercus serrata and Celtis sinensis selected as tolerant plants in field survey were used as experimental plants. Treatment with dolomite showed ameliorating effects by increassing n, Ca, and Mg com\ntents, and pH of soil and by decreasing Al content. Treatment of sludge showed similar effects by increasing N, Ca, Mg and organic matter contents, and by decreasing A1 content. But treatment of sludge did not show any effect on pH. Both soil ameliorators showed accelerating effects on the growth of experimental plants in Ulsan soil. But those effects in Yeocheon soil were somewhat different. Treatment of sludge showed accelerating effects of the growth of both sample plants but dolomitic liming did not so. From those results, we confirmed availability of sludge, a kind of industrial waste, as one of ameliorators of the polluted soil. In addition, we recognized that soil properties had to be considered to select soil ameliorators suitable for restoration of degraded ecosystems.

In view of greater attention given to the incidence of Polycystic Ovarian Syndrome (PCOS) in women of reproductive age, particularly in urban and semi-urban population in India, research works in both the regimens of orthodox and complementary and alternative medicines have been rejuvenated in recent years. We report here relative efficacy of two potentized homeopathic remedies, Calcarea carbonica (Calc) and Lycopodium clavatum (Lyco) used traditionally for the removal of ovarian cysts. These drugs are most frequently used based on guiding symptoms of individual patients. Effects of either of these remedies on its ability of removing cysts, along with amelioration of certain other hormones and hormone-related parameters of PCOS, such as follicle stimulating hormone, luteinizing hormone, Estradiol, Testosterone (Free/Total), Dehydroepiandosterone, Prolactine, Progesterone (17- Hydroxyprogesterone), TSH including T₃, T₄, and Insulin were studied. The Insulin-related parameters like changes in fasting or postprandial glucose levels were also studied. The mentioned hormones play some- direct or indirect roles in causing irregular menstrual cycle and PCOS. The data collected at three fixation time points, namely, at 6, 12, and 18 months were considered. Results showed that out of 40 patients initially having PCOS, cysts were totally removed in 21 patients along with amelioration of other relevant symptoms. Both Calc and Lyco had amelioration of similar nature. Results of this study therefore validate safe and effective use of both Calc and Lyco in homeopathy, to patients with basic guiding symptoms for either drug, and can be recommended for patients with PCOS as they do not have any reported side-effects.

The construction debris has been enormously increased since 90's because of a reconstruction and developing a new building site. Under the construction law, construction debris must legally recycle or reclaim at cost, but almost people have depended on reclamation of the illegal process to treat construction debris. Therefore, the environmental disruption and contamination have been begun the hot issue of society and in controversy with residents. With the consequence that indicates a substitute about an application of construction debris units is the most important thing for studying construction debris of quantity when the construction units are demolished. Nowadays, the area under the housing environment amelioration policies is getting rapidly old, then it is beyond anticipating reconstruction. Before construction units are demolished, generally three of four engineers investigate or predict the quantity of construction debris for two months. But this study is using the units of construction debris instead of the investigation and gets more precise data than investigation or prediction. In conclusion, the purpose of this study offers that units of construction debris can alternate the investigating of construction debris and curtail the expenses of labors and finances. Finally, those effects are going to make economical benefits covering the whole of the process of constructions.

Objectives: To investigate the scientific evidence of Korean Medicine (KM), papers on Socheongryong-tang (Xiaoqinglong-tang), which is frequently used in medical clinics or hospitals of Korean medicine, were collected and analyzed. Methods: Papers were classified by the registration of domestic or international journals, the year of publication, experimental models and the subjects of biological activities. The mechanisms of biological activity in accordance with therapeutic effects of Socheongryong-tang (Xiaoqinglong-tang) were noted. Results: Among 98 papers included, 21 were published in domestic journals whereas 35 were in Chinese journals and 43 in Japanese journals. Most reported biological activities were amelioration of asthma. Socheongryong-tang (Xiaoqinglong-tang) regulated interleukin and interferon and immunoglobulin, inhibited the production of nerve growth factor, endotheliln-1, nitric oxide, toll-like receptor-4, p-Akt and increased extracellular signal regulated kinase and cyclin D1, which led to decreased bronchi inflammation and bronchoconstriction, and inhibited the proliferation of airway smooth muscle cells, mucus secretion and airway hyperresponsiveness. In addition, Socheongryong-tang (Xiaoqinglong-tang) also restored tissues injured by asthma so that respiratory function recovered. Conclusions: Amelioration of asthma by Socheongryong-tang (Xiaoqinglong-tang) is supported by objective and scientific evidence.

The Rural Development Administration moved to Jeonju for the balanced development of the land. This situation required establishment of new research fields with soils appropriate to cultivation. We applied a variety of amelioration techniques to mature soils of new research fields of the National Institute of Agricultural Science (NAS) and evaluated effects of the integrated amelioration techniques. The schedule of amelioration was following: 1) location of research fields was determined, 2) surface and subsoil samples were collected separately, 3) after aligning the top level of research fields, subsoil and surface soil were re-established with soil amendment, 4) the green manure crops were grown four seasons to improve the uniformity and increase the organic content of the research field, and 5) drainage canal and/or underdrainage were applied to poorly drained fields. The last green manure crop was rape in RDA fields and green barley in NAS fields. The average height, fresh weight, and dry matter weight of rape in good condition were 123 cm, $3,938kg\;10a^{-1}$, and $651kg\;10a^{-1}$, respectively. The height, fresh weight, and dry matter of green barley, on average, were 97 cm, $3,013kg\;10a^{-1}$, and $1,004kg\;10a^{-1}$, respectively. In the chemical properties of paddy field, pH and levels of silicate, calcium, magnesium, and potassium were in appropriate range but organic matter content of $16g\;kg^{-1}$ was less than the optimum level. In the chemical properties of upland field, pH and levels of phosphorus, calcium, magnesium, and potassium were appropriate range but organic matter content of $12g\;kg^{-1}$ was less than the optimum range. Evaluation of well-adapted soil was performed. The field in RDA was classified into the superior class with points ranging from 90 to 95 by the field evaluation test. The fields in NAS were mainly evaluated as the superior class with points greater than 85. However, some fields in NAS remained low quality with scores between 80 and 83. Further soil amelioration practices were suggested to fields with low soil quality.

The purpose of this study is to explore the effects of difference in urban tree plantings on microclimate amelioration, and to suggest essential information for quantifying urban energy budgets and energy savings. This study was focused on measuring and analyzing air temperature and relative humidity in summer. Daytime air temperatures at places with 8%, 24%, 44%, 79%, and 100% cover of woody plants were, respectively, $0.6^{\circ}C,\;1.3^{\circ}C,\;2.4^{\circ}C,\;3.5^{\circ}C,\;and\;4.8^{\circ}C$ cooler, compared to a place with 0% cover. A 10% increase of woody plant cover was estimated to reduce the temperature by approximately $0.55^{\circ}C$. The temperature reduction effects were relatively greater between places with lower cover of woody plants than between those with higher cover. Woody plant cover and crown volume were the appropriate indicators which quantified the effects of tree plantings on air temperatures, based on the correlation analysis. Regression equations to estimate temperature change ($Y:^{\circ}C$) using woody plant cover ($X_1:%$) or crown volume ($X_2:m^3$) as independent variables are as follows: $$1nY=3.3233-0.0018X_1\;(r^2=0.99,\;p<0.0001)\;Y=27.5297-0.0019X_2\;(r^2=0.96,\;p=0.0007)$$

Fatty liver hemorrhagic syndrome (FLHS) is a metabolic disorder found in caged layer hens and causes reduced egg production and sudden death. Dandelion (Taraxacum coreanum, TC) and milk thistle (Cirsium japonicum var. ussuriense, CJ) are well known wild herbs inhabiting Korean peninsula and presenting antioxidative effects. This study investigated alleviate effects of these herbal mixture (6:4, w/w) composed of dried powder of TC and CJ against fatty liver in laying hens. The herbs mixture 5.0, 10.0, 20.0 or 40.0 g/kg feed was provided via feed admixture for 3 weeks to laying hens having FLHS. FLHS was induced by intramuscular injection of β-estradiol (2 mg/kg bw) 2 times per week for 3 weeks and supply with high caloric feed. Egg production rate was reduced from 76.2% at pre-treatment to 49.4% at 1 week and further decreased according to β-estradiol treatment. Increment of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (T-Chol) and total bilirubin (T-Bil) and decrement of serum superoxide dismutase (SOD) and glutathione peroxidase (GPX) with fatty liver were found by the treatment of β-estradiol. Supplementation of TC and CJ mixture via feed admixture recovered the reduction of egg production and attenuated serological changes and gross and pathological lesions of fatty liver with the best amelioration effects at 5 and 10 g TC and CJ mixture per kg feed. In conclusion, TC and CJ mixture attenuates FLHS by means of antioxidative effects. Further mechanistic study is required to explain TC and CJ's amelioration effects against FLHS in laying hens.

The present study deals with the amelioration by Lagerstroemia speciosa Linn. leaf extract against hepatotoxicity induced by carbon tetrachloride ($CCl_4$), which was evaluated in terms of serum marker enzymes like serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase, alkaline phosphatase, serum total bilirubin, total protein levels along with concomitant hepatic and antioxidants like superoxide dismutase, catalase, glutathione, glutathione peroxidase and lipid peroxidation enzymes were monitored. These biochemical parameters altered by the single dose level of $CCl_4$ (0.75 ml/kg body weight, i.p). Pre treatment with L. speciosa prior to the administration of $CCl_4$, at the doses of 50 and 250 mg/kg. body weight/day, p.o. for 7 days, significantly restored all the serum and liver tissue parameters near to the normal levels, respectively. Silymarin was used as a reference standard, prior to the administration of $CCl_4$ to rats. These findings indicate the protective potential of L. speciosa against hepato toxicity which possibly involve mechanism related to its ability of selective inhibitors of (reactive oxygen species like antioxidants brought about significant inhibition of TBARS suggesting possible involvement of $O_2{\cdot}-$, $HO_2{\cdot}$, and ${\cdot}OH$. In conclusion, the amelioration may be attributed to the synergistic effects of its constituents rather than to any single factor as the leaves are rich in tannins, sterols, flavonoids, saponins etc.

Probiotics improve the immune system. However, the effects of its lactic acid bacteria on atopic dermatitis relief and inflammation improvement is not fully understood. Recently, one of the probiotics, Lactobacillus helveticus HY7801 (HY7801), was found to have an anti-inflammatory effect. In this study, we investigated the effects of HY7801 on atopic dermatitis-induced animal models. After four weeks of oral administration, the group treated with HY7801 showed amelioration of the atopic dermatitis compared to the group receiving placebo. In the HY7801 treated group, the epidermal hyper-proliferation and collagen deposition were inhibited compared to the placebo group, and the secretion amount of the inflammatory factors, such as TNF-α, IL-4 were reduced. In conclusion, these results suggest that HY7801 acts as a functional probiotic via amelioration of the atopic dermatitis such as a decrease of epidermal hyper-proliferation, and collagen deposition and anti-inflammatory effects.
