The Laurence Moon-Bardet Biedl syndrome is characterized by obesity, mental retardation, visual impairment with retinitis pigmentosa, polydactyly, hypogonadism and renal manifestations. We experienced an 11 years old female with Laurence Moon-Baret Biedl syndrome associated chronic renal failure. She was diagnosed to have LMB syndrom according to the clinical manifestations of polydactyly on hands and feet, mental retardation, obesity, retinitis pigmentosa and chronic renal failure. She is on maintenance hemodialysis now.

MEVVA를 이용한 Ti이온 주입시 발생하는 용융금속이 마모에 미치는 영향

문봉호,양경욱 여수대학교 1998 論文集 Vol.13 No.2

The surface treatment technology such as CVD. PVD. Ion implantation has been developed to improve wear resistances of materials. Ion implanted surface treatment changes only surface characteristics of materials without any dimensional change. Hard coating by CVD, PVD makes region a material, since ion implantations do not have a boundary region, the spalling at the boundary is not occurred. This methods also has some advantages of the stable of size due to non-heating treatment. MEVVA which is a ion beam apparatus has merits of low cost and is usable to various metals, but occurs a droplet ranging from micron to tens of micron at ion implantations. This study clarifies the droplet influences on wear at Ti ion implantation into 1C-3Cr steel using SEM Tribosystem. Results show that the droplet occurred at ion implantation makes the severe wear. Therefore, the ion-implanted surface should be removed the droplet. 1C-3Cr steel implanted Ti ion by MEVVA is most effective for wear resistance under contact pressure 5.5GPa.

A series of sterilizing experiments have been made to determine the effect of microwave energy on Escherichia coli and Bacillus subtilis. For the analysis of the test, microwave sample digestion system (MDS-2000. CEM Co. USA) was used under the conditions of different sterilization duration and unequal intensity of microwave power irradiation onto the bacteria. According to the results of the research, E. coli and B. subtilis gradually decreased in proportion to the microwave's wattage and the heating time elapsed. The reaction kinetics of E. coli and B. subtilis could be represented by the first-order reaction and the value of specific death rate constants(k) of E. coli were calculated 25∼50% higher values than that of B. subtilis.

Chlorination of swimming pool water leads to many chlorinated products. The most frequent derivative is trihalomethane(THMs). This study was performed to investigate the distribution of THMs in swimming pool water and ambient air, and to determine whether THMs concentrations in swimmers' urine Were influenced significantly after swimming. Water samples were collected from 22 indoor and outdoor swimming pools. Concentrations of THMs in swimmers' urine determined before and after their stay in swimming pools. Results of the study as follows. 1. The concentrations of THMs in the indoor swimming pools water(41.85±73.22㎍/L) were significantly increased(p<0.05) in comparison with that of outdoor swimming pools (10.15±15.45㎍/L). The average concentration of THMs in indoor ambient was 51.2㎍/㎥, which was significantly higher than that of air quality. 2. As a results of regression analysis between THMs and water quality factors, the concentration of pH, residual chlorine and KMnO₄ consumption were highly correlated in indoor swimming pools. 3. In almost all cases, only CHCl₃ was quantifiable. The proportions of THMs in urine correlated roughly with those in water and the secretion of THMs increased significantly after swimming in the pools.

FPGA식 구현을 위한 HDTV 인터폴레이터 연구

문경태,문도성,신병식 서울産業大學校 1995 논문집 Vol.41 No.1

This paper propose the design and implementation of interpolation filter which interpolate subsampled data with the FPGA in HD-MAC decoder. Interpolation filter is FMH(FIR-Medain Hybrid) filter, hybrid filter composed of linear and nonliner filter, which has characteristics of good conservation of edge and good restoration of fine lines and robust to noise. Interpolator is implemented with FPGA of Actel company. It is proved that interpolator is well operated at 27MHz.

孝의 精神醫學的 意味

문경서,김상태 大韓神經精神醫學會 1983 신경정신의학 Vol.22 No.1

In the light of the concepts of the of modern western psychiatry, authors arrived at the conclusions as follows. Hsiao and Ti imply the true and “natural” human relationship originated from the interrelationship between the parents and their children with affection and respect as the basic element, and also the development of mature personality. From the viewpoint of psychoanalytic therapy, Hsiao and Ti mean the fundamental preventive measures from psychopathology from the beginnings.

情報시스템 Outsourcing의 發展 戰略에 관한 硏究

문태수,한경수 경주대학교 1996 論文集 Vol.8 No.-

This study presents the growth strategy of outsourcing service by finding out the differences of perception between user firms and system integration (SI) firms in the Korean outsourcing business. The result of data analysis reveals that there are significant differences between user firms and SI firms in some components of information systems(IS) outsourcing service. User firms selected integation of data center, as the most special changing issue, of IS environment changes. Meanwhile, SI forms choosed management of IS and VAN center, office automation(OA), management of global network, as the more important issues, in the application area of outsourcing. Also, both of them selected cost reduction and IS flexibility, as the most important issues, in the advantage of outsourcing. But they choosed the difficulty of control and the lack of operation knowledge in the disadvantage. And, they selected commonly overall IS consulting in the growth prospects of outsourcing. However, use firms choosed the introduction of client/server architecture, as the next important issues. SI firms selected the application of multimedia. These results show that there are some differences of perception between user firms and SI firms. SI firms are required to establish deep consideration and insight enough to diminish the differences in the strategic plan of outsourcing.

Formation of powders and piezoelectric properties of Pb (Zro.52 Tio.48) O₃ by chemical methods are described. The chemical methods were accomplished at 30℃∼70℃ for 1∼24 hrs. The PZT specimens of disc shape were sintered respectively at 1100℃, 1150℃, 1200℃ and 1250℃ for 5 hrs. The optimum sintering temperature were found to be between 1200℃ and 1250℃. The dielectric constant of the sintered samples reached a maximum while the dielectric dissipation factor showed a minimum at the sintering temperature of 1200℃. The value of planar coupling coefficient, Kp was about 0.43∼0.47 at 1200℃.

The purpose of this study was to evaluate the anxiety of inpatients in a general hospital in Daejeon. Data were collected through self-reported questionaires from January, 2003 to February, 2003, The anxiety was measured by Zung's Self-Rating Anxiety Scale. Analysis of data was done was descriptive statistics, t-test ANOVA and factor analysis. The results of the study were as follows : (1) The average score for the level of anxiety was 37.75±8.44 point (2) The anxiety items, such as sweating. apprehension, dyspnea, insomnia and restlessness showed the high score in inpatient. (3) Anxiety showed significant difference by education level(p<0.01), duration of hospitasization (p<0.01), prognosis(p(0.05), ward(medical/surgical) (p{0.05), experienc of admission (p<0.05). (4) According to the factor analysis, four factors of sweating, apprehension, dyspnea and restlessness showed high score in inpatient. Inpatient's anxiety characteristically showed more somatic symptoms than affective symptoms.

李京玧,文正大,文星培 釜山大學校 師範大學 1998 교사교육연구 Vol.36 No.-

Material Characteristics contents in the chemistry textbooks from elementary school to college were investigated to consider the effectiveness of curricular articulation. For this purpose, the eleven subjects of chemistry contents were selected from chemistry textbooks, and the learning purpose and contents were analyzed through the classification rules. The results of analysis showed that total articulation were relatively effective. But the gaps partly appeared in case of comparing with the level of intellectural development of student. On the based of this results a new concept diagrams were proposed through the structure diagrams considered both macro and micro aspect. To develop the curricular articulation between the school units it is important that textbooks should be with the consistent plan after the discussion with the actual teachers of the school units.
