It is hard to achieve the purpose of modeling after American public library without considering philosophical backgroud. The reason that American public library was developed in the 19th century was the influence of individualism. The intention of this study is to sugest to make plan of developing Korean public library in concordance with the common philosophy of Korean people.

Backgroud: Caudal blocks have been used for pain management in outpatient clinics. It is important to estimate the proper depth and angle in order to increase the success rate of the procedure. Methods: Data was collected from 60 patients who visited our pain clinic. We measured the depth of the needle's penetration and the angle of the needle at the insertion point when a caudal approach was confirmed by air flow method. We recorded age, sex, body weight and height, and calculated the ponderal index. Results: The depth from the skin to the caudal epidural space was a mean 2-4 cm ($3{\pm}0.4\;cm$). The angle at the needle insertion point was a mean 15-50 degree ($34.9{\pm}6.8$ degree). Conclusions: If we use the mean depth and angle as a guide, complications during the caudal epidural procedure can be avoided.

Backgroud and Purpose ; I intented to be helpful to treat diabetes through a clinical study of effect of soyangin Yangkyuksanwha-tang(凉膈散火湯). Methods : I studied 5 patients with upper diabetes who were diagnosed by Soyangin at department of Sasang constitutional Medicine in Dongeui Oriental Hospital during 1 year from August. 2001 to July. 2002. and then I investigated the clinical symptoms of the diabetics and analyzed level of examination after administration of Yangkyuksanwha-tang. Results and Conclusion ; Yangkyuksanwha-tang was administered to five diabetic patients, So-yang-in for 8 weeks. The symptoms such as frequent urination(P<0.05), thirst with frequent drinking water(P<0.01) have improved after the treatment. As results, level of FBS(P<0.01), total protein(P<0.05) and blood pressure(P<0.05) significantly decreased after administration of Yangkyuksanwha-tang.

Shell structures are widely used in a variety of engineering application, and mathematical solution of shell structures are available only for a few special cases. The solution of shell structure is more complicated when it has such condition as winkler foundation, other problems. In this study many simplified methods (analogy of beam on elastic foudation, finite element method and transfer matrix method) are applied to analyze a hemisphere-cylindrical shell structures on elastic foundation. And the transfer matrix method is extensively used for the structural analysis because of its merit in the theoretical backgroud and applicability. Therefore, this paper presents the analysis of hemisphere-cylindrical shell structure base on the transfer matrix method. The technique is attractive for implementation on a numerical solution by means of a computer program coded in FORTRAN language with a few elements. To demonstrate this fact, it gives good results which compare well with finite element method.

Backgroud: Immunotherapy using dendritic cells (DC) loaded with tumor antigens may represent a potentially effective method for inducing antitumor immunity. We evaluated the effectiveness of DC-based antitumor immune response in various conditions. Methods: DC were cultured from peripheral blood mononuclear cells (PBMNC) in myelogenous leukemia (ML) and lysates of autologous leukemic cells are used as tumor antigen. The effectiveness of interleukin-12 (IL-12) and CD40L (CD154) on the antigen presenting function of lysates-loaded DC was analyzed by proliferation, cytokine production, and cytotoxicity tests with activated PBMNC (mainly lymphocytes). For generating antigen-loaded DC, direct fusion of DC with ML was studied. Results: Antigen loaded DC induced significantly effective antitumor immune response against autologous leukemic cells. Administration of IL-12 on the DC based antitumor immune response showed higher proliferation activity, IFN-$\gamma$ production, and cytotoxic activity of PBMNC. Also, fused cell has a potent antitumor immune response. Conclusion: We conclude that lysates-loaded DC with IL-12 may be effectively utilized as inducer of antitumor immune reaction in ML and in vivo application with DC-based antitumor immunotherapy or tumor vaccination seems to be feasible.

Backgroud : Now a days, most studies for professional voice user have been performed after artificial voice abuse without consideration of environmental and personal factors, and occupational specificity, therefore those studies have some problems. Objectives : To make a basic guideline for the management of untrained professional voice user, practically we ananalyzed the voice of experimental group. Materials and methods : Just after working, the sustained vowel sounds of the 15 female telephone operators (subjective group) and the 20 normal female persons (control group) were analysed, using a history paper, acoustic analyzer and videostroboscopy. Results : The most common symptom in subjective group was dysphonia. Stroboscopic findings in subjective group were as following ; posterior chink 11 cases (73%), incomplete closure 2 cases (13%), anterior chink 1 case (7%). The mean maximal phonation time in telephone operators was 12.8 seconds and in control group was 16.8 seconds. Jitter, pitch pertubation quotient (PPQ), shimmer and amplitude pertubation quotient (ASQ) were significantly increased in subjective group than control group, but there is no difference between two group in fundamental frequency and noise to harmonic ratio. Conclusion : Untrained professional voice user needs professional career guidance and counseling. And when we manage the untrained professional voice user, we should consider specific occupational, personal and environmental factors as well as laryngeal factors.

Meridian collteral and meridian points have been he base of acupunurre therapy. Also the theory have composed the main portion of oriental medicine. But the mechanism and scientific backgroud has not been completely eastablished, and the research on the objectification of diagonosis of meridian collateral and meridian points, and acupuncture therapy has been necessary nowday. A new understanding of value of oriental medicine has been increasing, the scientific understanding of meridian collateral and meridian points should have been examined. In this paper, we observed meridian point on the morphology for objectification and meridian visulalization we try to meridian point to use methylene blue and optical equipment of high power magnifications. The result of this study suggest that we can observe ruggedness part on body surface to be estimated meridian point. It is observed to have similarity each time of different meridian points. Also, we can observe part alteration of meridian points each time which observed to use method of electronic resistance of unsimilarity on the morphology.

Backgroud and Purpose ; I intented to be helpful to treat adult disease through a clinical study of effect of vegetable ferment. Methods ; I studied 40 women of adipositas during 3 months from August. 2002 to July. November 2002, and then I analyzed level of examination after administration of vegetable ferment. Results and Conclusion ; vegetable ferment was administered to 40 women of adipositas for 3 months. The results level of cholesterol significantly decreased after administration of vegetable ferment, but triglyceride and HDL-C increased. And the results level of fat mass, fat ratio significantly decreased after administration of vegetable ferment but obesity, fat distribution of abdomen and body weight didn't decreased.

In order to calibrate the CR-39 Solid State Nuclear Track Detector (SSNTD), a closed -circulation type SSNTD-Calibration-System containing a radon-cup with the Millipore filter has been set-up, and the tracks produced on the SSNTD were measured for the known amount of radon concentration. Calibration factor for the time integrated radon concentration as a function of the track density on CR-39 was estimated to be $0.24{\pm}0.09(pCi/l)\;day/(Tr/cm^2)$.
