N/A Hobnail hemangioma(HH)is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi`s sarcoma or angiosarcoma.We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin.Histologically,ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles.She underwent treatment with surgical excision with primary closure.

The purpose of this study is to examine the history of the terms 'a critical thinking' and to survey the nature and the education of one. The critical thinking movement seems to have begun with the work of John Dewey from 1910 to 1939 and his use of the terms 'reflective thinking' and 'inquiry' which he based on the scientific method. From 1940 to 1961, the meaning of the term 'critical thinking' broadened to include the examination of statements. From 1962 to 1979, The meaning of the term 'critical thinking' narrowed to exclude problem solving and the scientific method and include only the assessment of statements. With the contributions of Robert H. Ennis, John E. Mcpeck. Harvey Siegel, and Richard W. Paul from 1980 to the present, the meaning of the term 'critical thinking' has broaden to include aspects of problem solving. The meaning of the terms 'critical thinking' and 'problem solving' overlapped and intersected each other. The core meaning of the critical thinking is the propensity and the skills for participate in the thinking activities with the reflective skepticism about the objects of thinking within one's cognizance. The aims for the teaching of critical thinking and reasoning is to be well used the logical skills to judge about the decision-making and problem solving situation. Formal and informal logical education is essencial to success for the education of critical thinking. The education of critical thinking have to be learned through the debate and the discussion.

Mucoepidermoid carcinomas, first reported by Volkman(1895), form 6% to 9% of all salivary tumors. Two thirds affecting the parotid gland and the remaining third, the minor glands. As we could know from its name, mucoepidermoid carcinomas originate from ductal epithelium including squamous, mucous-secreting, and undifferentiated intermediate cells. Histologically, it is classified as well-differentiated (low grade), moderately-differentiated(intermediate grade), and poorly-differentiated (high grade) types and the treatment method and prognosis are influenced from its histological grade. We have experienced two cases of mucoepidermoid carcinoma treated surgically with good results and now would like to report these with review of literatures.

After performing mandibular setback surgery, we found some changes in patterns and organs of speech. This investigation was undertaken to investigate the aspect and degree of speech patterns according to the amount of surgical setback in mandibular prognathic patients. Thirteen patients with skeletal Class Ⅲ malocclusion were studied preoperative and postoperative over 6 months. They had undergone the mandible setback operation via bilateral sagittal split ramus osteotomy(BSSRO). We split the patients into two groups. Group 1 included patients whose degree of mandibular setback was 6mm or less, and Group 2 above 6mm. Control group was two adults wish normal speech patterns. A phonetician performed narrow phonetic transcriptions of tape-recorded words and sen- tences produced by each of the patients and the acoustic characteristics of the plosives, fricatives, and flaps were analyzed with a phonetic computer program (Computerized Speech Lab(CSL) Model 4300B(USA) ). The results are as fallows : 1. Genera1ly, Patients showed longer closure duration of plosives, shorter VOT(voice onset time) and higher ratio of closure duration against VOT 2. Patients showed more frequent diffuse distribution than the control group in frication noise energy of fricatives. 3. In fricatives, frequency of compact from were higher in group 1 than in group 2. 4. Generally, a short duraction of closure for /ㄹ/ was not realized in the patient's flaps. Instead, it was realized as fricatives, sonorant with a vowel-like formant structure, or trill type consonant. 5. Abnormality of the patient's articulation was reduced, but adaptation of their articulation after surgery was not perfect and the degree of adaptation was different according to the degree of surgical setback.

The aims of this research study is to clear the differences of the learning effects and the cognition of Home Economics by sex in the middle school and to collect the future-oriented educational datas, after implementing the 6th education curriculum. The results of the study are as follows ; 1. Most of students had the cognition that Home Economics is a subject matter of a needful knowledge and skill for the family life, half students a cultural subject matter for the modern life. The former was supported by female students, the latter by male students. 2. Most of students were interested in actual training fields of cooking and hand-sewing, had a strong interest about a field of physical and social-psychological growth. The differences by sex were statistically significant in these fields. 3. Most of students had positive responses in the learning effects of Home Economics. The most useful field was cooking and the worst was the structure and method of sewing machine. 4. The shortage and the dissatisfaction in the learning of Home Economics were lacking of the actual training hours, the old-fashioned teaching methods and the shortage of teaching materials etc.

Seasonal variation of streamwater quality was observed every months from May 1997 to April 1998. Beside, temporal variation of streamwater quality and discharge were examined during rainfall-runoff period. Based on these data, we evaluated annual loading of pollutants discharged from forest basin. Main results obtained in this paper are as follows: Annual average pH was 7.31 and percentage of saturated DO concentration was represented 89-96% in each site. Streamwater quality was determined by amounts of rainfall, soil profile of sites and recharging underground water in rainy days. However, Streamwater quality was determined by only recharging underground water in sunny days. Annual runoff loading was investigated that Ca^(2+) is 23.8 ton/yr, Na^(+) is 7.0 ton/yr, K^(+) is 2.4 ton/yr. Cl^(-) is 1.9 ton/yr, NO_(3)-N is 1.6 ton/yr, Mg^(2+) is 1.7 ton/yr and SO_(4)^(2-) is 2.6 ton/yr. In rainy days, runoff loading was contributed to annual loading about 20%.

Nowadays, Water is deteriorating with several reasons such as increase of wastewater which is flowed into river and limitation of water resource. In this study, reuse water system was configurated using submerged membrane bioreactor(SMBR) system consisted of anoxic, selector, and aerobic tank with membrane to concentrate on plans for securing of water resource by reusing wastewater treatment effluen. This study was examined the feasibility of applying a Intermittently Internal Recycle Membrane Bioreactor to household wastewater treatment. The bioreactor was intermittently recycle to alternate anaerobic/anoxic condition while find was entered the early stage of anoxic period and membrane filtration occurred during aeration period. With about 5,000㎎/L of MLSS , 94.4% of TCOD_(Mn), 49.6% of T-N and 56.8% T-P, With about lO.OOO㎎/L of MLSS 94.0% of TCOD_(Mn), 51.3% T-N and 49.7% of T-P and With about lO.OOO㎎/L of MLSS (anoxic 1hr, anaerobic 2hr) 96.6% of TCOD_(Mn), 67.2% of T-N and 53.0% of T-P could be removed. Therefore, this study confirmed the possibility of the domestic water treatment using membrane bioreactor process with Intermittently internal recycle.
