  • Objective: Organization of articles have study design, make hypothesis, sample gathering, statical analysis and feasibility of conclusion and medical articles must be continuously published and be continuously monitored in order to raise the quality of research. Main characteristics of oriental pediatrics research in korea can be summarized as the increase of the number and the advances methodology in research. The purpose of this study was to analyze the trends and evaluate the level of oriental pediatrics. Methods: The subjects were 244 articles published during the from 1986 to 2002 in 'The Journal of Korean Oriental Pediatrics' In this study, all the articles pressed in this journal were divided into three classes, Iiteratural, experimental and clinical articles and these were surveyed their chronological and thematic distribution Results: Classifying the articles in the journal of the korean oriental pediatrics, there were 103(42.2%) literatural articles, 90(36.9%) clinical articles, 51(20.9%) experimental articles. Clinical articles is gradually increasing although Iiteratural articles is decreasing. About disease in oriental pediatrics, immunoactivity was 13, rhinitis and growth was 12, allergy was 11 and diarrhea was high frequent in literatural articles, statistics of chief complaints and rhinitis was high frequent in clinical articles, immunoactivity was high frequent in experimental articles. Conclusions: As can be seen from the above results, there has been many these published using various experimental methods and relating to oriental pediatrics on the symptoms and diseases and their treatments, but unfortunately they were not enough the transmission of meaning of theses and contribution of learning, because how to do theses was not unifonn and description was not evident.

  • PURPOSES : This study is to predict the Sound Pressure Level(SPL) obtained from the Noble Close ProXimity(NCPX) method by using the Extended Kalman Filter Algorithm employing the taylor series and Linear Regression Analysis based on the least square method. The objective of utilizing EKF Algorithm is to consider stochastically the effect of error because the Regression analysis is not the method for the statical approach. METHODS : For measuring the friction noise between the surface and vehicle's tire, NCPX method was used. With NCPX method, SPL can be obtained using the frequency analysis such as Discrete Fourier Transform(DFT), Fast Fourier Transform(FFT) and Constant Percentage Bandwidth(CPB) Analysis. In this research, CPB analysis was only conducted for deriving A-weighted SPL from the sound power level in terms of frequencies. EKF Algorithm and Regression analysis were performed for estimating the SPL regarding the vehicle velocities. RESULTS : The study has shown that the results related to the coefficient of determination and RMSE from EKF Algorithm have been improved by comparing to Regression analysis. CONCLUSIONS : The more the vehicle is fast, the more the SPL must be high. But in the results of EKF Algorithm, SPLs are irregular. The reason of that is the EKF algorithm can be reflected by the error covariance from the measurements.

  • Background: The relation ofsurvivin gene expression to survival and surgical prognostic factors in the patients with endometrial carcinoma is unclear. Materials and Methods: In this study, 62 cases who were operated due to endometrial carcinoma were investigated between 2003 and 2011 in the the gynecological oncology clinic of Female Disease Training and Investigation Hospital of Etlik Zubeyde, Hanim, Turkey. Clinical and surgical prognostic factors were investigated by screening the records of these cases. With the standard streptavidin-biotin immune peroxidase method, cytoplasmic and nuclear expression of survivin was investigated in sections with specific antibodies (1:100, diagnostic Bio Systems, USA) primer. The aim was to elucidate any relation between survivin expression and defined prognostic factors and survival. Results: There was no statistically significant relationship between cytoplasmic and nuclear indexes identified for survivin and age, body mass index, the levels of preoperative hemoglobin, platelet and Ca 125, stage, grade, lymph node meastasis, the number of meta statical lymph nodes (total, paraaortic and pelvic), myometrial invasion, serosal invasion, adnexal involvement, the presence of acid in the first diagnosis, the involvement of omentum, the adjuvant treatment application of the cases, the presence of recurrence and rate of mortality (p>0.05). Statistical significance was noted for the presence of advanced stage lymph node metastasis (pelvic, paraaortic, pelvic and paraaortic), serosal involvement, positive cytology, lymph vascular space invasion, intra abdominal metastasis, and omentum involvement. When investigated the relation between cytoplasmic and nuclear survivin indexes and total survival, the result was not statistically significant (p>0.05). Conclusions: In our study, there was no statistically significant relationship between the rates of cytoplasmic and nuclear survivin expression with identified prognostic factors and total or non-disease survival.

  • Self-etching priming bonding system was recently developed in order to simplify the clinical skills & save chair time after continuous improvements on dentin bonding agents. To test the magnitude of microleakage of a new "self-etching priming bonding agent" using sound premolar 4th, 5th, 6th generation dentin bonding agent was applied. Measure the magnitude of infiltration to the gap of enamel-restoration interface and dentin-restoration interface. After bonding of composite resin to sample surfaces according to the manufactures direction and 500 times thermocycling on dwell time 30 second, and microleakage was measured by the ratio of the depth to the axial wall and the magnitude of infiltration. Afterward analyzed by ANOVA test. The result were as follows ; 1. Enamel groups showed lesser microleakage (Group I, II, III, IV) than dentin groups(Group V, VI, VII, VIII). (p<0.05) 2. There are no statical differences among the dentin groups, in enamel groups, group IV showed more microleakage than group I, II, III. (p<0.05). For a clinical acceptance, better enamel marginal adaptation is required.

  • Purpose: The purpose of this research is to provide basic informations for the encouragements of premature infants' breast feeding. Method: From August 10 to October 9, 2002, we have carried out a statical research which surveyed 148 mothers of premature infants registered in NICU. The sample had generated cluster-randomly from 25 General Hospitals, all over the Korea peninsula and being surveyed with 74 questionnaires. Result: Mean hospitalized day of premature infants was 27.9 days. The mean total feeding period was 19.1 days and continuous breast feeding period 12.4days. They were interested in breast feeding education-they answered that they would join the breast feeding education if they were given the chance 87.8%. There was significant relation between babies fed only breast milk and the body weight of birth(p<.05). The reasons why mother gave the baby her breast milk include 'for her baby's health' and 'people said breast milk is good for babies' with a portion of 99%. The main reason why mothers could not execute breast feeding was 'the deficit of breast milk volume' 50.0% and other reason were 'because of start to support more nutritions '18.2%, 'difficulty to carry out the breast milk to hospital'13.6%. The reasen why mothers could not try breast feeding at first were 'deficit of breast milk volume'37.0%, 'not to be prepared for breast feeding because of unexpected delivery'32.6%. Conclusion: We need a program to inform importance and excellent of the breast feeding and a plan to increase the premature infants' breast feeding through the importation of fortifier.

  • The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

  • In design of prestressed concrete structures, structural analysis is performed normally several times for selection of adequate sectional dimension and tendon amount. Especially for precast segmental multi-span bridges. time consuming structural analysis process due to time dependent material properties and structural system change could be effectively reduced by use of a reduced-span bridge model. 5-span and 3-span bridges are selected as reduced-span models for the 10-span full bridge to investigate the acceptability in practical design. The analytical results of deflection, total moment, statical moment, and ultimate moment of the reduced span-models are compared with those of the 10-span full bridge. Application of the load factors to structural analysis for ultimate moment calculation in prestressed concrete is reviewed and a rational method is proposed.
