Vertigo occurs when there is conflict between the signals sent to the brain by various balance- and position-sensing systems of the body. Injury to or diseases of the inner ear can send false signals to the brain indicating that the balance mechanism of the inner ear (labyrinth) detects motion. Inner ear disorders, such as benign paroxysmal positional vertigo (BPPV), Meniere's disease, vestibular neuronitis, or labyrinthitis. Vestibular neuronitis is an inflammation of the vestibular nerve, which is located in your inner ear. In this case, She has vertigo occured suddenly and continued even when the person lies completely still. It may be accompanied by nausea and vomiting. She has taken herbal medication and treated by acupunture. Her symptoms become disappeared after 3 days and All most symptoms were disappeard. In conclusion, It is required to classify vestibulopathy into vestibular neuronitis or labyrinthitis. In this case we diagnosed her case as vestibular neuronitis. Her symptoms of vestibulopathy recovered fast by Korean traditional medical therapy.

Objectives : This study was carried out to evaluate anti-oxydative, anti-tumor effect for clinical application of Whakijogyungtang (WJT) Results : 1. DPPH radical scavenging activities of WJT water extracts(Exts) were in proportion as concentration of WJT.(3 ${\mu}g/ml:12.6{\pm}2.3$ %) 2. ABTS+ scavenging activities of WJT water Exts were more effective in high density.(3 ${\mu}g/ml:4.3{\pm}1.6$ %, 10 ${\mu}g/ml$: $11.8{\pm}2.5$ %, 30 ${\mu}g/ml:45.3{\pm}3.2%$ 100 ${\mu}g/ml$: $62.7{\pm}4.8%$) 3. Hydrogen peroxide$(H_2O_2)$ scavenging activities of WJT water Exts were effective.(3 ${\mu}g/ml:4.7{\pm}0.8$ %, 10 ${\mu}g/ml: $8.2{\pm}1.6$ %, 30 ${\mu}g/ml:19.5{\pm}3.2$ % 100 ${\mu}g/ml$: $24.6{\pm}3.8$ %) 4. Anti oxidative effects against linoleic acid were not effective. 5. The generation of $O_2\;^-$ in S-180 cells were according to the concentration of WJT water Exts, specially effective over 100 ${\mu}g/ml$ concentration. 6. The SOD activities in S-180 cells were in proportion as cytotoxicity against S-180 cells of WJT water Exts. 7. The GPx activities in S-180 cells were in proportion as cytotoxicity against S-180 cells of WJT water Exts(more effective on 300 ${\mu}g/ml$ and 1000 ${\mu}g/ml$ concentration), but the catalase activities in S-180 cells were not effective. 8. The results of activites against multi-drug-resistance(MDR) of WJT were as follows. 1) In water Exts from WJT, cytotoxicity against AML-2/D100 with vincristine($IC_{50:}39.78$ ${\mu}g/ml$) was more effective than without vincristine($IC_{50:}$ 183.58 ${\mu}g/ml$), Cross resistance(CR:3.85) was not effective, and anti-MDR activites(RF) was effective.(RF:3.85) 2) In hexane fraction, cytotoxicity against AML-2/D100 with vincristine ($IC_{50:}130.88$ ${\mu}g/ml$) was more effective than without vincristine ($IC_{50:}293.10$ ${\mu}g/ml$) and anti-MDR activites(RF) was effective.(RF:4.61) 3) In chloroform fraction, the cytotoxicity against AML-2/WT and AML-2/D100 was not effective. 4) In ethyl acetate fraction, cytotoxicity against AML-2/D100 with vincristine($IC_{50:}36.43$ ${\mu}g/ml$) was more effective than without vincristine ($IC_{50:}73.07$ ${\mu}g/ml$), Cross resistance(CR:0.53) was not effective, and anti-MDR activites(RF) was effective.(RF:2) 5) In butanol fraction, the cytotoxicity against AML-2/WT and AML-2/D100 was not effective. 6) In $H_2O$ fraction, the cytotoxicity against AML-2/WT and AML-2/D100 was not effective. Conclusion : These result suggest that WJT has antioxidative effects, anti-tumor effects by apoptosis of free radical$(O_2\;^-)$ activity, and anti-MDR activites(especially hexane and ethyl acetate fraction).

대수 발달의 단계에 관한 드모르간의 관점 연구

유미경,김재홍,권석일,박선용,최지선,박교식,Yu, Mi-Kyung,Kim, Jae-Hong,Kwon, Seok-Il,Park, Sun-Yong,Choi, Ji-Sun,Park, Kyo-Sik 한국수학사학회 2008 Journal for history of mathematics Vol.21 No.4

이 연구에서는 대수 발달의 단계에 관한 드모르간의 관점을 그가 사용한 용어를 바탕으로 산술, 보편산술, 기호대수, 의미적 대수의 순서로 나누어 논의한다. 드모르간은 즉각적으로 계산 결과를 얻는 산술과 문자기호를 사용하는 보편산술을 구분하였다. 그에 의하면, 보편산술은 산술에서 대수로 이행하는 과도기적 단계인 바, 이 단계에서 이상하고 불합리한 현상들이 발생하기에 대수가 필요하게 된다. 대수 발달의 단계에 관해 드모르간이 가진 관점의 특징은 기호의 의미가 사라진 규칙 체계 즉, 기호적 계산법을 얻은 후, 이 기호적 계산법 자체를 논리적으로 만들기 위해 기호에 확장된 의미를 부여하여 의미적 계산법으로 만든다는 것이다. 단일대수는 -1에 확장된 의미를 부여함으로써 만들어지고, 이중대수는 $\sqrt{-1}$에 확장된 의미를 부여함으로써 만들어진다. 드모르간에 의하면, 대수 발달에서는 앞에서 제시된 체계의 불완전성에 주목하여 다음 체계를 이끌어낸다. In this paper, we discuss about De Morgan's view on the development of algebra according to following distinctions: arithmetic, universal arithmetic, symbolic algebra, significant algebra. De Morgan thought that the differences between arithmetic and universal arithmetic lie in the usage of letters and the immediate performance of computation. In his viewpoint, universal arithmetic is a transitional phase, in which absurd phenomena occur, from arithmetic to algebra and these absurd phenomena call for algebra. The feature of De Morgan's view on the development of algebra is that symbolic calculus which consist of symbol system without symbol's meaning is acquired, then as extended meanings are furnished to symbols, symbolic calculus become logical so significant calculus is developed. For example, Single algebra is developed, as an extended meaning is furnished to a symbol -1, and double algebra is developed, as an extended meaning is furnished to a symbol $\sqrt{-1}$. According to De Morgan, a symbol system is derived from the incompleteness of a prior symbol system.

This research attempted to check elder's actual condition of sleep that lives in medium to small town city and to provide basic data for nursing intervention of elder's health management. This research was predicative survey research by the targeted subject of elders over 60 years old who voluntarily agreed to participate on this study. The duration of collecting data was from 2006-09-23 to 2006-11-27 and the researcher interviewed the subjects using the questionnaires and got the replies in person. This research consisted of a total 65 questions, that is, 10 questions on general characteristic, 36 health related questions including snoring, incontinent, questions on disease and 19 questions(PSQI, 1989) on sleep quality. By using SPSS 12.0 on collected data, real numbers and percentage was obtained and it was analyzed by t-test and ANOVA. Followings are the result of this research. 1. When looking at this research's subject's health related characteristics, 49.0% had snoring and among these, 28.0% were less than 65 years old and 72.0% were more than 65 years old. Also, 73.7% of elders who are less than 65 years old have snoring and 42.9% of elders who are more than 65 years old has snoring which indicates as you get older, snoring decreases. Subjects' health characteristics are 49% snores and among these, 28.0% were less than 65 years old and 72% were more than 65 years old. 2. This research's subject average hours of sleep was 6.82±1.97 and mostly sleeps between at 9-11 p.m. and wakes up between at 4-6 in the morning which indicated elders sleep early and wake up early. The average time takes to go into the sleep was 48.37±66.40 minutes, and within 10 minutes was 36.50% which was the most and more than 1 hour was 21.20%. 3. The subject's average sleep quality was 6.2 out of 21, the highest of sleep quality of lower area score was sleep latency stage which was 1.32 point and those of who has good quality of sleep were 46.3%. 4. For sleep quality according to subject's health related characteristics, subjects who has incontinent has 8.46 point while who has no incontinent had 5.46, therefore sleep trouble is higher and decreases quality of sleep.(p= .001) From the result of this research, elders go into sleep and wake up earlier than other age range, and snoring decreases as they get older. People who snore were 52.0% male and 48.0% female, and if there is incontinent, quality of sleep differs significantly. From the basis of these results, continuous and extensive research on sleep of elders who resides at home or hospital is necessary and moreover research on main causes related on elder's sleep is also necessary.

The purpose of this study was to investigate the bonding of resin- based root canal sealer, AH26 when the sealer was applied as a thin layer between dentine and gutta-percha surface. In this study forty non-caries extracted human molars and resin-based root canal sealer(AH 26, DeTrey/Dentsply, Germany) were used. Disks of gutta-percha, 6mm in diameter.6mm thick (Diadent/Dentsply, Korea) for thermoplastic obturation were used and dentin surfaces were treated with 2% NaOCl(Group 1) or 2%NaOCl+17% EDTA(Group 3). Disks of gutta-Percha, 6mm in diameter.6mm thick (Diadent/Dentsply, Korea) for conventional obturation were used and dentin surface were treated with 2% NaOCl(Group 2) or 2%NaOCl+17% EDTA(Group 4). Enamel was removed by a horizontal section 1mm below the deepest portion of the central occlusal groove by using a watercooled low speed diamond saw. A second horizontal section was done around cementoenamel junction. Exposed dentin surface was cut to approximately $8{\times}8{\;}mm$ rectangular shape and was ground against 320, 400, 600 grade silicon carbide abrasive paper serially. After grinding, the dentine surface were soaked in a solution of 2% NaOCl for 30 minutes and twenty of specimens were treated with 17% EDTA solution for 1 minute. The treated specimens were washed and dried, Root canal sealer, AH26 was prepared according to the manufacture's instructions The Gutta-percha and dentin surface were coated with a thin layer of the freshly mixed seal or. The specimens were left overnight at room temperature. After their initial set, they were transferred to an incubator at $37$^{\circ}C$ for 72 h. After 72 hours, resin blocks were made. The resin block was serially sectioned vertically into stick of $1{\cdot}1mm$. Twenty sticks were prepared from each group. After that, tensile bond strength f3r each stick was measured with Microtensile Tester Failure patterns of the specimens at the interface between gutta-percha and dentin were observed under the SEM(x1000) and Stereomicroscope (LEICA M42O, Meyer Inst., TX U.S.A) at 1.25 x25 magnification. The results were statistically analysed by using a One-way ANOVA and Tukey's test. The results were as follows; 1. Tensile bond strengths($mean{\pm}SD$) were expressed with ascending order as follows: Group 1, $3.09{\pm}$ 1.05Mpa : Group 2, $6.23{\pm}1.16MPa$ : Group 3, $7.12{\pm}1.07MPa$ : Group 4, $10.32{\pm}2.06MPa$. 2. Tensile bond strengths of the group 2 and 4 used disks of gutta-percha for conventional obturation were significantly higher than that of the group 1 and 3 used fir thermoplastic obturation. (p < 0.05). 3. Tensile bond strengths of the group 3 and 4 treated with 2% NaOC1+17% EDTA were significantly higher than that of the group 1 and 2 treated with 2% NaOCl. (p < 0.05). 4. In analysis of failure patterns at the interface between sealer and gutta-percha, there were observed 49 (61%)cases of adhesive failure patterns and 31 (39%) cases of mixed failures patterns.

Erysipelas is a type of cellulitis in skin infection generally caused by group A ${\beta}$-hemolytic streptococci. An erysipelas skin lesion typically has a raised border that is sharply demarcated from normal skin. The underlying skin is painful, intensely red, hardened, swollen, and warm. Objectives: We reviewed three cases of erysipelas patients who hospitalized in Dongshin Univ. Suncheon Oriental medicine hospital from June 2001 to June 2002. Methods : We treated them with Galgunhaegitang(葛根解肌湯) for interior diease of Taeumin(太陰人) and also used acupuncture and cupping therapy. Results and Conclusions ; We had significant effects of Galgunhaegitang(葛根解肌湯) for three cases of erysipelas patients. So if the patient were a Taeumin(太陰人), we can consider using Galgunhaegitang(葛根解肌湯) for erysipelas. We can also use antibiotics properly in case there are high fever or open wounds.
