Ozone is a strong oxidant and a powerful disinfectant. In general, it has been used in drinking water treatment during last 100years. Ozone dissolution features are defined by the two categories of ozone contactors, bubble-diffuser and sidestream ozone contactor. Currently, sidestream-injection systems are gaining in popularity but operating cost might be slightly higher. Sidestream ozone system dissolve ozone into a sidestream flow via an injection setup or in the main process flow stream in some sidestream arrangements. The sidestream flow is subsequently mixed with the main process flow stream, which is directed to a reation tank or pipeline for oxidation and disinfection reactions. The purpose of this study is to suggest optimal operating pressure, to figure out the static-mixer effect and to understand the microbubble characteristics of ozone to improve dissolution efficiency.

This study was carried out to investigate the effects of prechlorination and algae growth on THMs generation. The sample water obtained from Paldang Dam which is a main source of raw water for the Seoul metropolitan area. THMs concentration in the sample water was investigated in water treatment process prechlorifiation, chemical coagulation, and sand filtration. And also, THMs concentration were analyzed in the water which cultured algae in laboratory. The results were as follows 1. The THMs concentration produced by prechlorination unit process were increased in control (not purified) but decreased in process of purification. 2. The THMs concertration can reduce by increasing the number of cleaning filters. 3. The main precursor in raw water for the THMs generation was supplied by algae growth. So as to reduce the THMs concentration in water supplying system, it is the best method to manage algae growth in water body of Paldang reservoir.

This study examined education and training as variables related to ethical behaviors of child counselors. The four sub-variables of this study included main educational/training background (academic career, major in last degree, and treatment modality), source of education in ethics, experience of educational psychoanalysis, and experience of supervision. The 136 child counselors participating in this study were administered the Inventory for Ethical Behaviors of Child Counselors (Yoo & Kim, 2(06). Data were analyzed by frequency, percentage, average, standard deviation, Cronbach's a, t-test, one way ANOVA, and multiple regression analysis. Results showed that main educational/training background (academic career, major in last degree, and treatment modality), experience of educational psychoanalysis, and experience of supervision were significant variables related to ethical behaviors of child counselors.

We treated a 18 year-old female patient. The main symptoms were Low back pain, Dyspepsia, Anorexia. She want to check blood test spontaneously and we diagnosed her as subclinical hypothyroidism and prescribe herbal medicine three times a day. We observed clinical symptoms and Free T4, T3, TSH levels. After the treatment, The main symptom were improved and TSH levels fell. This case shows that herbal medicine has an effect on subclinical hypothyroidism.

Objectives : The aim of this study is to report the case improved through Korean Medicine Including Herbal Medicine with Astragali radix, Rehmannia glutinosa as main ingredients, Acupuncture and External Preparation on the treatment of contact dermatitis. Methods : A patient with contact dermatitis was diagnosed through Korean Medicine and treated with Herbal Medicine with Astragali radix, Rehmannia glutinosa as main ingredients, Acupuncture and External preparation. The Degree of itching was assessed with Visual Analogue Scale(VAS) and the severity of wheals and redness on lesion site was assessed through photography. Results : VAS decreased from 9 to 1 and wheals and redness on lesion site was disappeared. Conclusions : According to the result, These findings suggest that Korean Medicine can be effective for the treatment of contact dermatitis.

This experimental work aims at developing and investigating a lightened concrete by the addition of treated straws. The used formulation is based on that of an ordinary concrete which is composed of sand and gravel as the main aggregates. The properties of the straws are improved by using one of two treatments before their use: the hot water and bitumen. Henceforth, the main objective of this study is to assess the mechanical characteristics of different formulations with different compositions and treatments on straws. The obtained results have shown that the addition of straws improves its lightness property. However, it decreases the compressive and flexural strengths as well as decreases the modulus of elasticity and increases the dimensional variations. Set into comparison to the concrete with untreated straws, the treatment of straws by hot water or by bitumen improves most of the characteristics.

This study examined ethical dilemmas experienced by child-counselors and coping behaviors they practiced in context. The analysis was performed for 30 child-counselors in Seoul and Kyunggi-do, Participants were asked to describe a self-report in an interview with the main researcher. Data were categorized, quantified and examined in terms of five ethical dimensions derived from antecedent research. The five ethical dimensions are "confidentiality and protection of privacy", "professional competence", "informed consent", "informing clients of the nature of treatment modality", and "adequacy and effectiveness of treatment". This study contributes basic data for the development of an inventory for the measurement of ethical practice for child counselors.

For the treatment of bronchial stenosis due to trauma, inflammatory and neoplastic lesion, bronchoplastic procedure in the interest of preservation of lung tissue are relatively new developments in the field of thoracic surgery. We reported on case of bronchoplasty using to pericardial patch for the treatment of bronchial stenosis due to chronic inflammation. The patient was 26 years old female and chief complaint was respiratory difficulty. Bronchogram revealed diffuse stenosis of left main bronchus about 4cm and especially, at just below the carina marked narrowing of lumen and fine serration in the wall. At the time of operation, longitudinal incision was made at left main bronchus about 5cm and reconstructed bronchus using to pericadial patch at membranous compartment of bronchus. The postoperative course was uneventful and post-operative follow up bronchography showed that improvement of bronchoplastic segmented region.
