The purpose of this study was to explore the comparative effectiveness of the developed communiacation-skill-training(CST) and belief-change-training (BCT) on the change of the marital conflict resolution styles. In order to accomplish the purpose, this study was to set up the following hyphotheses: There are statistically significant differences among CST, BCT and control group subjects on the change of mean scores for the conflict resolution styles. The measurement instrument using in this study was Thomas-Kilmann Conflict mode instrument(1974) composed of five subscales which is collaborating, compromising, forcing, accomodating and avoiding style. Subjects used in this study were the thirty three female volunteers who wanted to enroll in the trained and nontrained groups. They were assigned to one of the three groups(CST, BCT and control group). Twenty two females in the trained groups received a six days, twelve hour training program to either CST or BCT. The nontrained group participated only in the pretest and posttest phase of the study. SPSS/PC 4.01 package was used to analyze the data from this study. In order to test statistical differences among mean scores of the subscales obtained after treatments carried out 2(pre and posttest) X 3(training group) ANOVA of the mixed design, simple main effect analysis and scheffe method. The conclusions obtained from the results are as follows: 1. CST and BCT not showed positive change effect on the collaborating conflict resolution style. 2. CST and BCT not showed positive change effect on the compromising conflict resolution style. 3. CST and BCT showed positive change effect on the forcing conflict resolution style. 4. BCT showed positive change effect on the accomodating conflict resolution style, but CST not showed positive change effect on the accomodating conflict resolution style. 5. CST and BCT showed positive change effect on the avoding conflict resolution style.

Acrophobia is a symptom of feeling an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used to treat the acrophobia. In these days the virtual reality technology has been applied to treat such an anxiety disorders. But former acrophobia treatment systems use only patient's score of the questionary to appraise. The new system developed in this thesis uses not only patient's score of the questionary but also biomedical signals such as HR, GSR amplitude to increase the objectivity and quantitativity. The experimental results show that HR and GSR amplitude are useful for decision of acrophobia. We will apply this system to the acrophobia patient and be able to offer better medical treatment for mental illness in near future.

This work investigates a new model that predicts the equilibrium solubility of gaseous component with polymer film. The new model regards the gas concentration in fluid phase as depressing factor in desorption from the surface of the film. The final mathematical form describes actual observation well with its second order form. The over all figure of the equilibrium solubility is sigmoid that one sees frequently in experiments. The only disadvantage of this model is the bulk concentration appears in denominator that induces the expression becomes infinite if the concentration is none. Insertion of one constant added to the concentration term in the denominator defeats this shortcoming. The following is the mathmatical form of the net rate of dissolution and the equilibrium solubility, respectively. □ Also, this paper presents the logical method obtaining the parameters from the experimental equilibrium data for the ethylene dissolution in LDPE film that had incorporated a ceramic powder with selective gas permeability. Finally, the dependency of the equilibrium parameters, KA, Cmax, the others to the weight fraction of the powder and appears to be linear and presented to follow : The parameters were calculated by soluble equilibrium constant, KA, maximum soluble concentration, Cmax and soluble rate constant, k+ for ethylene gas permeated through LDPE packaging films containing the ceramic powders 0∼6wt% at 20℃, the above model being applied. The values showed 1.45×106∼3.70×106[(㎤/mol)2], 2.30×10-3~2.92×10-3 [mo1/㎠sec]and 0.273∼0.405[㎤/mol sec], respectively.

Medications or conitive-behavior methods have been mainly used as a treatment of alcoholism, lately the virtualy technology has been applied to the kink of alcoholic disorders. A virtual environment makes him having avility to over come the drink. In this study, we were implemented by making panorama images and 3D object modules using 3D MAX. VRML, JAVA. And the BAR stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a alcoholism and and without a liquor bottle, heart rate was measured during experiment, and also measured a person's HR after the virtual reality training. We demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

기주특이적 독소 생성 Alternaria spp.와 비병원성 A. alternata의 계통분류학적 유연관계를 규명하기 위하여 기주특이적 독소 생성 Alternaria 6균, 비병원성인 A. alternata 그리고 비교균으로서 소형포자를 형성하는 A. brassicicola, 대형포자를 형성하는 A. solani의 ribosmal DNA의 5.8S를 포함한 ITS영역의 염기 서열을 분석하였던 바 다음과 같은 결과를 얻었다. 1. Alternaria spp.의 rDNA ITS영역의 염기서열 크기는 548∼562bp였으며 5.8S rDNA에서는 비교종간에 서로 일치하였고 ITS I에서는 종간 뚜렷한 차이를 보였다. 2. 기주특이적 독소 생성 Alternaria spp.의 rDNA의 ITS영역의 염기서열은 비병원성인 A. alternata의 염기서열과는 서로 일치하였으나 A. brassicicola와는 3%, A. solani와는 7%의 염기서열 차를 보였다. 3. 기주특이적 독소 생성 Alternaria spp.는 비병원성 A. alternata와 진화적으로 매우 가까운 유연관계를 나타내었다. The regions of internal transcribed spacer(ITS) including 5.8S ribosomal DNA(rDXA) from six host-specific toxin(HST) producing Alternaria spp. nonpathogenic A. alternata. A. solani and A. brassicicola were sequenced to assess their relationship in taxonomy. There was no difference in the sequences of ITS including 5.8S rDNA among the HST-producing Alternaria spp. and nonpathogenic A. alternata. However, the sequences of HST-producing Alternaria spp. were different from those of A. solani and A. brassicicola by about 7% and 3%, respectively. These results suggest that HST-producing Alternaria spp. are evolutionarily very close to non pathogenic A. alternata although they have host-specific pathogenecity.

측정방법에 따른 콩 성분의 항산화효과 비교

문갑순,권태완,류승희 한국콩연구회 2003 韓國콩硏究會誌 Vol.20 No.1

콩 성분의 항산화효과를 측정을 위해 DPPH법, FRAP법, TEAC법을 이용하여 이들 방법간의차이를 비교하고, 콩의 항산화효과를 측정하는데 가장 적합한 실험방법을 확립하고자 하였다. 콩의 유효 성분 중 항산화효과와 관련있는 isoflavone 및 phenolic acid의 표준품을 이용하여 항산화효과를 측정하였고, 항산화효과의 비교를 위해 Trolox, ascorbic acid, glutathione의 활성을 측정하였다. DPPH법, FRAP법, TEAC법의 3가지 항산화효과 측정방법에 따른 genistein의 효과가 가장 높았고 DPPH나 FRAP의 경우는 gentisic acid, syringic acid, ferulic acid 등의 phenolic acids의 활성이 높게 나타났고 isoflavones의 효과는 매우 낮게 나타났다. 항산화효과를 측정하기 위해 다양하게 이용되고 있는 방법들간에는 차이가 있음을 알 수 있었으며 TEAC법의 경우 glutathione 및 콩의 주요 성분인 isoflavones과 대부분의 phenolic acids의 활성을 평가할 수 있어 유용한 방법으로 여겨진다. To establish the proper assay for measurement of antioxidative activities in soybean, the main components relating to their antioxidative effects were measured by DPPH (α, α-diphenyl-β-pycryl-hydrazyl radical), FRAP (ferric reducing/antioxidant power), and TEAC (Trolox equivalent antioxidant capacity) assay. The antioxidative activities of commercial isoflavones (genistein, daidzein, and glycitein) and phenolic acids, which were well known as main antioxidative ingredients in soybean, were measured by three methods and compared the activities with Trolox, ascorbic acid, and glutathione as reference antioxidnats. By the FRAP and DPPH assay, gentisic acid, syringic acid and ferulic acid showed the strong antioxidative activities, while isoflavones and glutathione showed very low or undetectable activities . In contrast genistein, p-coumaric acid, and ferulic acid showed remarkable antioxidative activities by the TEAC assay. Therefore. it is proposed that TEAC assay is suitable for detecting antioxidative activity of soybean.

Although the use of the antibiotics has minimized the dangers of the spread of odontogenic infection to adjacent important organs, sometimes the fatal cases, such as Ludwig's angina, mediastinitis, intracranial complications from the odotogenic infection, may be occurred. The odontogenic infections or oral and maxillofacial region may involve the intracranial area through systemic circulation or by direct spread into the intracranial cavity. Headache, malaise, loss of appetite, chills, fever, vomiting, apathy, and irritability are usually followed by more specific involvement of the nervous system. We experienced one patient who died of intracranial complication from odontogenic infection. So we report the case and the literatures about intracranial involvements following odontogenic infections and dental procedures.
