It is research about special quality of ozone gas concentration and dissolved ozone concentration that show according to change of flow rate when liquefied ozone gas in water. If increase flow rate of ozone gas, ozone concentration increases being proportional and amount to fixed flow rate, dissolved ozone concentration was measured low. When ozone concentration How rate 1000 [ppm], dissolved ozone concentration smelted to flow rate 1.5[Q] for 28 [min] is $0.1740{\sim}0.8020[mg/l]$. Could know that half-life is most short by 3 minutes 8 seconds in flow rate 1.5 [Q]. And ozone smelted 20 minutes later after half-life measurement became disjointing all.

Objectives : The purpose of this study is to report the effect of Korean medical treatment in patient with Herpes Zoster and hyperemesis gravidarum during pregnancy. Methods : 10 weeks pregnant patient with Herpes Zoster and hyperemesis gravidarum was treated by herbal medicine ( Bosaeng-tang ) and acupuncture. We measured visual analogue scale (VAS) and observed the change of skin lesion. Results : After treatment, vesicles and crusts of right buttock and lower leg clearly dis appeared. Patient no more suffered from nausea and vomiting. VAS (Visual analogue scale) of pain changed 8 to 0. After 7months, the patient gave birth to a healthy child. Conclusions : This case report shows that the Korean medical treatment is useful and safe in the treatment of Herpes Zoster and hyperemesis gravidarum during pregnancy.

Cultural characteristics and phylogenic relationships were investigated and classified among collected strains in Pholiota spp. which contain P. adiposa, P. squarrosa, P. nameko etc. They were tested on the four different media(PDA, MCM, YM, MEA) and sawdust(Alder, Oak, Pine, Popular) substrates. There was a little variation according to the media and sawdust substrates, although PDA and popular sawdust substrate seemed to be better. Most strains showed white colonies, but some strains were brown. Mycelial growth length differed according to the strains. To classify species, the internal transcribed spacer regions(ITS) of the ribosomal DNA(rDNA) repeats from Pholiota spp. were amplified using polymerase chain reaction(PCR) and then sequenced. According to the analysis of ITS sequences, they were classified into five clusters. Their spacer regions were $644{\sim}700$ nucleotides in length. The reciprocal homologies of each ITS region among these strains were ranged from $49.6{\sim}99.9%$. The phylogenic analysis might give a criterion to classify species in the collected strains.

Decision tree algorithms are used extensively for data mining in many domains such as retail target marketing, fraud dection, data reduction and variable screening, etc. CHAID(Chi-square Automatic Interaction Detector), is an exploratory method used to study the relationship between a dependent variable and a series of predictor variables. In this paper we propose and CHAID algorithm by cube-based sampling and explore CHAID algorithm in view of accuracy and speed by the number of variables.

Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. In this paper we used k-means clustering of several clustering techniques. The k-means Clustering Is classified as a partitional clustering method. We analyze 2002 Gyeongnam social indicator survey data using k-means clustering techniques for environmental information. We can use these outputs given by k-means clustering for environmental preservation and environmental improvement.
