  • The magnetic and magneto-optical properties of the Tb/Co multilayers as a function of the layer thickness and the ratio of Tb/Co thicknesses were studied. When the thickness of Tb layer was $12{\AA}$, the maximum perpendicular anisotropy energy and the maximum thickness ratio which displays the perpendicular anisotropy were obtained. This result indicated that the Tb-Tb and Co-Co pairs as well as the Tb-Co pairs contribute to the perpendicular anisotropy. The Kerr rotation angle, $({\theta}_k)$ was proportional to the perpendicular anisotropy energy and was inversely proportional to the average spin dispersion angle, $(\alpha)$. The maximum $({\theta}_k)$ of $0.28^{\circ}$ was obtained in the film of $12{\AA}$ Tb and the thickness ratio of 1.55. The abnormal hysteresis loops were appeared during the aging treatment because the coercivity difference between the Co layer and the Tb layer was increased by the preferential oxidation of Tb.

  • It was found that the diapause in the silkworm egg is induced by the action of the diapause hormone secreted from the suboesophageal ganglion, and "esterase A" affects protein metabolism in oocyte and egg. In this connection, some changes in protein metabolism of silkworm egg according to embryonic developments could give some information on the diapause, using Ouchterlony Test. Antigenicity of the protein of silkworm egg was detected through antigen-antibody interaction among the extracts of rabbit blood. Furthermore, existence of the specific antigen was also detected according to embryonic development, using the adsorption test. The results were obtained as follows: 1 Detection of antigenicity The antigenicity of silkworm egg was ascertained by inoculating it into a rabbit, but positive results were shown in most of the silkworm eggs tested, whereas the antibody specific to a certain antigen was not detected. 2. Detection of the common antigen It was demonstrated that most of the antigen could incite the common antibodies, but the specific antibody formation was not detected in a few antigens, even though the nonspecific antibody formation was displayed. 3. Detection of the specific antigen It is suggested that there are the specific antigens detectable in each treated eggs by the adsorption test.

  • 목적 : 본 연구는 catalase 유전자 다형성이 중풍의 발병과 관련이 있는지 알아보기 위해 수행되었다. 대상 : 경산대학교부속구미 한방병원에 입원한 중풍환자 86 명과 종합건진센터에 내원한 중풍기왕력이 없는 건강인 165 명을 대상으로 하였다. 방법 : 각 그룹에서 개개인마다 DNA를 분리 정제한 후 Taq polymerase로 증폭하여 한천 겔에서 전기영동을 하여 잘려진 DNA fragment의 양상을 관찰하였다. 결과 : T/T, T/A, A/A의 세가지 유전자형이 검출되었으며 중풍군과 건강인 사이에 통계적인 유의성이 나타나지 않았다. 결론 : 이상의 결과를 통하여 catalase 유전자 다형성은 중풍의 발병과는 관련성이 없는 것으로 사려되며 더 많은 환자를 대상으로 다른 환경요인 또는 유전자와의 연관성에 대한 심도있는 연구가 필요하다고 하겠다.

  • In recent years, there has been more reconstruction and redevelopment of apartments rather than efforts to consider alternative to extend the life time of the apartments. It is essential to try to develop ways to adequately maintain and to use the apartment facilities efficiently in order to preserve earth environment and the limited resource. However, tacking research on the effects obtained through remodelling and maintenance have interfered with the vitalizing of the market. The objective of this study is to propose criterions and methods with which to evaluate adequacy of maintenance management. A survey was performed to investigate important maintenance methods in order to obtain advices that can smoothly progress improve apartment maintenance management. This study applied AHP(Analytical Hierarchy Process) methods for reasonable maintenance in apartment. Through this study, the flow of apartment maintenance market is elevated to reaching the level in advanced nation.

  • 1) Higher yield of red color was observed by the isolated strain (Monascus D-7) than the type cultures in steamed rice medium. 2) In a case of Monascus purbigerus IAM 8004, best yield of color was obtained at Lin's submerged culture medium containing 1% wheat bran, 2% starch and 3% corn meal instead of rice powder as carbon source. However, in a case of isolated strain (M. D-7), good result was shown at 1% rice bran and 2% starch as a source of carbon in Lin's medium. 3) Good yields were obtained from both strains in Nishikawa's medium which was added with 3% defatted soybean flour. 4) There were no significant differences in pigment extractability among solvents. Extracted pigment was stable in wide range of pH and heat, whereas relatively unstable in sunlight. 5) Toxicological study of extracted pigment determined $LD_{50}$ at 0.2539g/20g, when injected in mouse. When injected in to mouse in 25% ethanol solution: considering the toxicity of ethanol, the toxicity of pigment itself is believed to be none.

  • Tension headache is one of the most common form of headache. It may occur at any age, but is most common in adults and adolescents. One cause of this muscle contraction is a response to stress that induces changes and imbalance on autonomic nerve system. And it is not easy to classify the type of tension headache simply in oriental medicine. In this case, we described a 25-year old woman who diagnosed as tension headache. She complained headache with nausea and vomiting, and her condition was improved through oriental medical treatment.

  • We have studied the effect of auricular acupuncture on postoperative nausea and vomiting (PONV). 100 female patients undergoing transabdominal hysterectomy were entered into the study. The patients were divided into two groups (auricular acupuncture treatment group and non-treatment group) to test the effectiveness of auricular acupuncture. acupuncture consisted of needle insertion in one ear at four points: sympathetic, stomach, shinmoon and occiput. Before the operation, the above points were punctured perpendicularly by the thumbtack-type needle, leaving its handle lying flat on the skin surface. There was no significant difference in age, weight, height and duration of anesthesia among the two groups of patients. There was a cignificant difference between the control group and auricular acupuncture treatment group in the incidence of vomiting at the first 12 h after surgery 68% and 30%, respectively, p<0.01) No noteworthy side effects fbom treatment were observed. auricular acupuncture is effective in reducing nausea and vomiting after transabdominal hysterectomy in female patients.

  • The immunogenicity of investigational combined vaccine, composed of the Japanese encephalis virus(JEV) and the polysaccharide capsule(Vi) of Salmonella typhi covalently bound to tetanus toxoid(TT) was evaluated in mice. The mice immunized with combined vaccine elicited higher anti-Vi Immunoglobulin G(IgG) as well as anti-JEV IgG levels than the mice immunized with Vi-TT or JEV alone. The combined vaccine produced four-fold increase in anti-Vi IgG level than Vi-TT alone. In JEV the combined vaccine was significantly more immunogenic than JEV alone and induced six-fold increase in IgG level. Adsorption of combined vaccine onto aluminium hydroxide gel also enhanced IgG level for both Vi and JEV.

  • Kawasaki disease (KD) is a systemic vasculitis that can affect many organ systems. Renal manifestations include pyuria, hematuria, proteinuria, tubulointerstitial nephritis, acute renal failure, hemolytic uremic syndrome, or renal scarring. Although its precise pathogenesis remains unknown, it is considered an autoimmune disease. In the literature, it has been reported that KD may develop in conjunction with urinary tract infections. However, many of these previous studies did not use imaging methods such as renal sonograms, dimercaptosuccinic acid renal scans, and voiding urethrocystograms. We report a case of an 8-month old male infant with high grade vesicoureteral reflux, who developed incomplete KD after recurrent pyelonephritis. Acute pyelonephritis can be an early manifestation of KD. Such cases require the evaluation of urinary tract anomalies according to the guidelines for the management of urinary tract infections.
