We think that we know what alopecia is. But in detail, we have nothing of alopecia areata. Many kinds of alopecia make us be confused. So, I studied the history ( name, cause, treatment etc,) of alopecia areata through the oriental and occidental medical books. As a result, the investigation of alopecia areata was led to the next conclusions 1. Synonyms of alopecia areata are Bandok(斑禿), Docbal(禿髮), Guyjidu(귀지두), Guychedu(鬼剃頭), Gyobalsun(咬髮癬). 2. Generally, the cause of alopecia areata is classified into three groups. Those are hyeolheopungjo(血虛風燥), Chichehyeoleo(氣滯血瘀), Gansinbujoc(肝腎不足). 3. The important internal uses of alopecia areata are Sineungyangjin-Dan(神應養眞丹), Soyosan plus Tonggyuhwalhyeoltang(逍遙散合通竅活血湯), Chilbomiyuom-Dan(七寶美髥丹) etc. 4. The important external uses of alopecia areata are haeaetang(海艾湯), Suncheukbackyeop(鮮側柏葉), Old ginger(老薑), Leaf of mulberry tree(桑葉) etc. 5. The kinds of Acupunture therapy are Maehwachim(梅花針), Chilsungchim(七星針), Ear acupunture(耳針) etc.

Objectives : This study was conducted to assess the effect of Chunwangbosim-dan(CB) on the autonomic nervous system by using heart rate variability measurement. Methods : The eligible subjects were composed of the healthy female group of ages 25 to 30 years. They were divided into two groups, the CB group(n=16) and the control group(n=16). We measured the heart rate variability respectively for 3 times at 14:00, 16:00, and 17:00. In the CB group, subjects were administered CB at 15:00. For the measurement values, Mean Heart Rate and SDNN(standard deviation of the NN intervals) were used as time domain analysis, and HF(high frequency), LF(low frequency), and LF / HF ratio were used as frequency domain analysis. Results : The degree of LF changes in the CB group was significantly lower than control group at 1 hour after administration. Conclusions : We suggest that Chunwangbosim-dan may be useful for stabilization of the autonomic nervous system by controlling sympathetic nerve in healthy people.

Objectives: In order to identify the anti-inflammatory and analgesic properties of Salvia miltiorrhiza (Dan-Sam), widely used in Korean traditional medicine, an in vitro screening system was designed using pGL3, a luciferase reporter vector, and the tumor necrosis factor (TNF)-${\alpha}$ and cyclooxygenase (COX)-2 as target genes. Methods: The promoter regions of each gene were generated by PCR using the human chromosome as template DNA, and inserted into pGL3 vector with Kpn I and Hind III. The final construct was transfected into human myelomonocytic leukemia cells (U-937) that could be differentiated and activated by phorbol 12-myristate 13-acetate (PMA) or lipopolysaccharide (LPS). Using this system, the anti-inflammatory and analgesic effects of several herbal extracts regarded to have the medicinal effects of diminishing body heat and complementing Qi were tested. The chemicals PD98059 and berberine chloride were used as controls of the transcriptional inhibitors of TNF-${\alpha}$ and COX-2, respectively. Results: Salvia miltiorrhiza (Dan-Sam) demonstrated significant decrease of TNF-${\alpha}$ and COX-2 mRNA in the in vitro assay system. In MTT assay, Salvia miltiorrhiza (Dan-Sam) did not significantly inhibit the survival and proliferation of human myelomonocytic leukemia cells (U-937). Conclusions: Salvia miltiorrhiza (Dan-Sam) was found to exhibit the significant medicinal properties of anti-inflammatory and analgesic effects.

The oriental-western Literatural study of Amnesia, the results were as follows. 1. esia is caused by qi-depression resulted from excessive thought and deficiency of the kidney resulted from congenital deficiency and deficiency of the heart, the disharmony between the heart and the kidney, phlegm, stagnant blood, loss of the blood etc. resulted from deficiency of the heart blood. 2. The treatment method of Amnesia is as follows, the highest frequence was growing blood-tranquilization-regulating spleen, in descending order removing phlegm-stagnant blood-relaxing the mind and invigorate the heart-spleen-kidney and much tonification qi-blood and growing nutrient qi-manifesting source qi and regulating the harmony between the heart and the kidney and maintaining patency for the flow of gi were the most treatment method. 3. The treatment medicine of Amnesia is as follows, the highest frequence was Kuei Bi Tang(歸脾湯) in decending order Jeng Ji Whan(定志丸), Su Seng Whan(壽星丸), Chun Whang Boo Sim Dan(天王補心丹), Ju Jak Whan(朱雀丸), Doo Dam Tang(導痰湯), Yin Sin Kuei Sa Dan(引神歸舍丹), Ga Gam Go Bon Dan(加減固本丸), Ryung Ji Go(寧志膏), Jang Won Dan(壯元丹), Tong Ol Tang(通鬱湯). 4. In oriental medicine functional physiology and pathology was significant in differential diagnosis and treatment and in western medicine it was explained organically and psychologically. 5. In western medicine As one of memory disorder Amnesia is divided into psychogenic amnesia and organic amnesia, and organic amnesia is divided into anterograde amnesia and retrograde amnesia and psychogenic amnesia is divided into localized amnesia, generalized amnesia selective amnesia.

Removal of subgingival calculus is essential for the success in periodontal treatment. Subgingival instrumentation is used for the removal of all bacterial plaque and calculus. In this study, two types of anterior curet were used on ant. teeth to conduct subgingival scaling and root planing. The remaining amount of calculus was evaluated according to type of instrument, depth of pocket, and tooth surface. 24 teeth extracted from patients being treated at Dan Kook University dept. Perio. were used. 4 surfaces per tooth a total of 96 areas were evaluated. 12 teeth treated with Gracey No. 1-2 was used as the control group and 12 teeth treated with Mini-five curet No. 1-2 was the experimental group. The 4 surfaces of the teeth {buccal, mesial, lingual or palatal, distal) were observed under a stereomicroscope and the images were captured 3 times per surfaced with a CCD. The image were observed on the monitor using a $10{\times]10$ grid produced with the Microsoft power point. The amount of calculus remaining was evaluated 3 times per surface. The results were as follows. 1. There was no significant difference in remaining calculus according to the pre-treatment pocket depth, and tooth position{Mx. or Mn). 2. The Mini-five curet showed better results than the Gracey curet but there was no statistically significant difference. 3. In both Gracey curet group and Mini-five curet group the lingual(or palatal) surface showed significant difference compared to the other surfaces(p<0.05). From the results above, it is thought that when treating ant. teeth consideration of the tooth surface is more important than the choice of instrument.

Jang Gyung Ak thought the Yang Gi was the basis of life. This is why he said doctors should emphasize on preserving Yang Gi. Before his emphasis on Yang Gi he had to study and criticize the medical concept of HaGan, DanGye and DongWon. By criticizing and overcoming their medical concept's fallacy and limitations, he made his own medicine. JangGyungAk found the importance of YangGi in the theory of changes. In the "the Book of Changes" it is said the rising movement of YangGi is expressed by recipricals and propels heaven and earth, yin and yang to change. The phenomenon of life is also a reciprocal and is lead by YangGi, and so medicine should value Yang Gi. Because the phenomenon of life is lead by this Yang Gi, it is right to base changes of diseases and organize pattern identification. The pattern identification JangGyungAk presented as two Gang six Byun sets its base on YangGi.

In this study, vertical motion of a Tuned Liquid Column Damper(TLCD) is measured by a variable voltage measurement system in the electric field and design parameters of the TLCD are determined. First, nonlinear damping term of the TLCD is replaced as the equivalent viscous damping term. The natural frequency and damping ratio of dynamic characteristics of the TLCD are verified. In addition, a novel liquid level measurement system is developed for measuring vertical motion of the TLCD. For the experimental achievement, experimental characterizations of natural frequency and damping ratio of the TLCD are undertaken utilizing the developed variable voltage sensing. Also, shake table testing is performed to determine the dynamic characteristics of the TLCD. As a result, the feasibility of the proposed liquid level measurement system is verified by comparison with the capacitive type wavemeter.
