Literally, the mean of Tae-gye is highest brook. And on the basis of the acupuncture theory, Tae-gye point is the Soo earth point and source point of the Kidney Channel as well. In addition, Tae-gye point is one of the Yang-Returning Nine points. We were trying to study bibliographically on the Tae-gye point because Tae-gye point can be used very broadly across the symptoms in the theoretical aspect described above. As a results, we found out that according to the classical books of acupuncture, Tae-gye point is entering point of the Meridian Water as a source point and can be used at both Kidney-Sufficient Syndrom and Kidney-Deficient Syndrom. And Tae-gye can be applied to the disease of kidney or bladder that is urogenital symtoms, Also, Tae-gye is an useful option of tooth-ache, asthma, indigestion, constipation, edema etc whose cause is related with decrease of Kidney ki.

This study was conducted to investigate the repellent efficacy of essential oils (Origanum vulgare, Pimpinella anisum, and Tanacetum cinerariifolium) and four plant extracts (Agastache rugosa, Capsicum annuum, Citrus reticulata, and Ginkgo biloba) against Tribolium castaneum (adults and larvae) and Plodia interpunctella (larvae). Gas chromatography/mass spectrometry analysis revealed the presence of carvacrol, anethole, and jasmolin I as the predominant constituent in O. vulgare, P. anisum, and T. cinerariifolium, respectively. Furthermore, ethyl hexopyranoside, 9,12‐octadecadienoic acid, cyclopentanol, and 2‐cresol were identified in A. rugosa, C. annuum, C. reticulata, and G. biloba, respectively. The repellent efficacy of each essential oil, plant extract, and the combination of oils was evaluated using a specially designed cylinder trap for 120 h. Among the three oils, O. vulgare and T. cinerariifolium had greatest repellent efficacy against P. interpunctella larvae. T. cinerariifolium exhibited effective repellence against the adults and larvae of T. castaneum. Therefore, O. vulgare (O) and T. cinerariifolium (T) were selected for further investigation of combined effects. Two essential oils were mixed in three different ratios of OT1 (1:3), OT2 (1:1), and OT3 (3:1). The repellent efficacies of OT1 and OT2 against the adults of T. castaneum were significantly greater than that of OT3. OT1 was effective against the larvae of T. castaneum, whereas OT2 was effective against the larvae of P. interpunctella. OT1 enhanced the repellent efficacy by approximately five times against larvae of T. castaneum, compared with that of T. cinerariifolium. Overall, OT1 was selected as the best repellent substance against all the tested insects.

IEEE 802.11 MAC mainly applies two techniques to avoid possible collisions : physical carrier sensing and RTS/CTS handshake with the virtual carrier sensing. However, these schemes incur the spatial waste, because they do not avoid all packet collisions in practice, and put the excessive off-limit area of transmission as the surrounding area including potential interference with the ongoing transmission, In this paper, IFMdnterference-Free MAC) is proposed to minimize the interference and allow the efficient spatial reuse, In the IFM, the distance between a sender and a receiver is reported to any node overhearing the ongoing transmission, and neighboring node makes its deferment decision adaptively based on the communication distance. We show that IFM provides significant improvement in throughput and packet drop ratio through simulations using NS-2.

Objectives : The Internalized Stigma of Mental Illness (ISMI) scale designed to measure the subjective experience of stigma with sub-scales measuring Alienation, Stereotype Endorsement. Perceived Discrimination, Stigma Resistance, and Social Withdrawal. The purpose of this study was to examine the reliability and validity of the Korean version of ISMI. Methods : The subjects were 194 schizophrenic patients and 205 peoples with depressive disorder. K-ISMI, CES-D (The Center for Epidemiologic Studies Depression Scale) and Self Esteem scale were performed. Results : Results showed that the ISMI had high internal consistence and split-half reliabilities. The internal consistency coefficients (Cronbach alpha) of each subscale ranged from .83 to .93. The validity of the ISMI was investigated by principal axis factoring analysis, yielding 5 factors of alienation, Perceived discrimination, negative stereotype, stigma resistance, devaluation and social withdrawal. 5 subscales explained 60.67% of total variance. Concurrent validity was supported by comparisons against scales measuring related constructs. As expected, the ISMI had positive correlations with CES-D, and it had negative correlation with self-esteem scale. Subsidiary analysis showed that schizophrenic patients showed higher internalized stigma than depressed patients. Conclusion : Overall, the findings support the utility of ISMl as a tool to evaluate internalized stigma of persons with mental illness. Interventions that can lessen internalized stigma may well hasten the recovery process in individuals with mental illness.

최경임,이진태,안봉전,최은영,박찬익 경산대학교 생명자원개발연구소 2002 생명자원과 산업 Vol.6 No.-

지금까지의 발모관리는 의학적인 차원에서 원형탈모, 남성형 탈모증 및 약제에 의한 병리학적인 연구가 있었으나 미용적인 관리에 대한 연구가 거의 없었다. 따라서 본 논문에서는 약품을 사용하지 않고 순수한 발모촉진 화장품과 두피관리 프로그램을 중심으로 발모관리를 통해 탈모개선 효과를 비교검토하였다. 탈모자를 여러 그룹으로 선발하고 발모제를 달리 처방하여 모발의 굵기, SEM 촬영, 수분측정, 정상인의 모발상태와 탈모자의 모발상태를 TEM 촬영하여 비교 분석하였다. 먼저 두피관리 전과 후의 수분함량의 차이는 평균 16% 상승하였다. 발두께 비교실험에서는 정상모에 비해 탈모자의 모발이 최대 38.6%가 작은 것으로 나타났으며, 모유두와 모간의 촬영사진에서는 탈모자의 모유두는 덜 발달되어 있었고, 변형된 모유두 형태가 많았다. 전자현미경을 통한 모표피의 SEM촬영에서는 탈모자나 정상모나 표면적으로 큰 차이는 없었다. 오히려 탈모자의 경우에는 모발이 약하고 건강하지 못하기 때문에 화학적인 처방을 하는 염색이나 펌 등을 하지 않아서 모발의 큐티클 층은 정상인의 모발보다 건강한 상태로 보였다. 두피측정에서는 관리 후 A, B, C 군의 비교에서 세 그룹 모두 두피의 현저한 개선효과를 보였다. 육모제를 사용한 A, B, Group과 영양제를 사용하지 않고 스캘링과 관리를 한 C군 모두 발모효과가 있었으며, 두피관리를 전혀 하지 않는 D군은 발모효과나 두피의 개선효과는 전혀 없었다. 전자 현미경을 통한 모발의 단면 촬영에서는 정상모발이 탈모자의 모발보다 피질이 부드럽고 풍성하게 잘 형성되어 있었다. 탈모자의 경우는 매우 심각한 고민거리인데 본 실험의 결과 가장 효과적인 발모 관리는 육모제로 두피의 혈액순환을 도와주고 평소생활에서 Brushing으로 모공이 막히지 않도록 꾸준한 손질을 함으로써 발모 및 두피개선이 될 수 있다는 것을 확인할 수 있었다. Twenty working people from 30s to 50s whose hairs were in the process of losing were selected for this study. They were divided into four groups as A, B, C and D. Their hairs were sampled to compare the thickness of the hairs through a optical microscope. Using hair care products from two marketing companies, once a week, Group A and B were treated scalp scaling and steam treatment during ten minutes. After applying vitamin cream the scalp was examined using a bio-beam every 5 minutes. Group C did not receive any vitamin cream but had the same treatment as A and B. Group D used no vitamin cream and receives no treatment. The results were as follows: In Comparison losing hair surface with healthy hair surface by electronic microscope, losing hair took place when the scalp has keratin or too much fat. After comparing the amount of moisture before and after care by a moisture measurement instrument, the amount of moisture has been outstandingly increased. As a result of observing hair root and hair shaft, hair root appeared to be less developed than healthy hair. These results showed that hair care is need to be constantly research and illuminate with regard to the proper care.

The author observed the effects of retrograde infusion of water soluble contrast media(Telebrix 30) on the rabbit submandibular glands and compared the effects of different degrees of filling. 26 rabbits were divided into 2 groups of 12 each as experimentals and 1 group of 2 as normal controls. One experimental group was filled with 0.2 ml and the other with 0.4 ml. Right submandibular gland of each rabbit was infused with contrast media and left one with physiologic saline as a experimental control, at a constant rate of 0.12ml/min. using an infusion pump via the main excretory duct. Immediately after the infusion of contrast media, oblique lateral radiographs of the glands were made with occlusal film in order to confirm the glandular filling. The rabbits were sacrificed after varying periods (1, 8, 24 hours and 3, 6, 10 days) and the tissues were prepared for light and electron microscopic examination. The results were as follows: 1. In glands filled with 0.2 ml contrast media, the initial changes were a few vacuole formation in the acini and slight dilation of the intralobular duct. The moderately severe changes such as vacuole formation in the acini, the abnormal substructure within the secretory granule, dilation of acinar and intercalated duct lumen, scalloping of striated duct lumen and inflammatroy cell infiltrate were observed at 3 days. The general appearance was successively recovered, so the tissue had a normal appearance at 10 days. 2. In glands filled with 0.4 ml contrast media, the most prominent alterations such as severe acinar atrophy, decreased number of secretory granules, proliferation of connective tissue stroma and pronounced inflammatory cell infiltrates appeared at 6 days. Although the general appearance returned to be almost normal at 10 days, acinar cells showed some atrophy and decreased secretory granules. 3. In glands subjected to 0.4 ml infusion, the alterations were more severe and the recovery was slower than those seen in the glands to 0.2 ml infusion.

p-형 Si(100) 기판 위에 성장시킨 Bi_(3.25)La_(0.75)Ti₃O_(12) (BLT) 박막의 전기적 특성

최은경,박문흠,김현주,하태곤,강민주,김상수 昌原大學校 基礎科學硏究所 2003 基礎科學硏究所論文集 Vol.15 No.-

Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

백태현,박재하,김화중,조은경,최대경 충남대학교 의과대학 지역사회의학연구소 1992 충남의대잡지 Vol.19 No.1

Rapid diagnostic tests for tuberculous meningitis are urgently needed because delayed treatment increase the already high mortality rate of this disease. In this study, the 30-kDa protein antigen that purified from the unheated culture filtrate of M. tuberculosis H_37Rv was examined for its diagnostic usefulness in detecting mycobacterial antibody in cerebrospinal fluid(CSF) by the enzymelinked immunosorbent assay(ELISA) and Western blot. The mean ELISA values of IgG antibody activity to 30-kDa antigen in CSF of 12 patients with tuberculous meningitis and 17 non tuberculous patients were 0.479±0.245 and 0.051±0.024, and for the IgM antibody, were 0.375±0.223 and 0.065±0.039, respectibely. The sensitivity and specificity were 100% and 94% for IgG antibody, and 75% and 94% for IgM antibody, respectively. Western blot analysis was the same as that results of ELISA. In the positive determination, however, Western blot could be easily determined by the demonstration of distinct band of 30-kDa molecule. From the above results, it is suggested that the 30-kDa antigen is useful for the diagnosis of tuberculous meningitis, and Western blot shows promise as a useful immunological method for the diagnosis.

오은경,박형건,배기현,최옥진,최은경,최창근,한진희,정태천 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.4

Effects of (±)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of (±) -camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with (±)-camphor at the doses used. Administration o(±)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that (±)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 213 in male ICR mice.
