The number of small businesses being founded in the nation is constantly increasing and various kinds of aggressive efforts are being made to have competitiveness. As such, political support by the government with regards to small businesses that has productivity and competitiveness needs to increase. Foundation of small businesses is being promoted by the Government to boost the economy, and interest in foundation of the business is high amongst not only college students but even general workers. Thus, the purpose of this study is to examine problems regarding foundation of small businesses and to give new businesses competitive edge by presenting political answers to these problems. After analysing status and current issues of foundation of small business, the paper suggested positive policy alternatives. Existing studies on small businesses were focused on promotion of small and medium distributors, and studies on policy alternatives aimed directly at promoting the businesses are insufficient. Further studies are needed to examine political alternatives from point of view of roles and support of non-profit organizations that the Government is responsible for support of small business.

Lupus erythematous panniculitis is a chronic inflammatory disease of subcutaneous fat that occurs in 2-3% of patients with systemic lupus erythematosus. Lupus erythematous panniculitis typically presents with firm, indurated subcutaneous nodules or plaques commonly developed in proximal extremities, trunks, head and neck. Face, breast and upper extremities involvement with lupus erythematous panniculitis has been infrequently reported. We report a case of lupus erythematous panniculitis developed in a 27-year-old female confirmed by histologic features and laboratory findings.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

To examine the effects of the welding residual stress on Mode I fatigue crack propagation behavior, 3mm thickness SS41 steel plate was welded by an Auto-matic Submerged Arc Welding. Initial residual stress and relaxation residual stresses according to each stress ratio were measured. The fatigue crack propagation behavior from the region of compressive residual stress to region of tensile residual stress was analyzed. The results predicted by the Forman's equation using the superposition approach of the respective stress intensity factors for the initial residual stress and for the applied stress according to each stress ratio were compared with experimental data. The validity of the superposition approach was investigated. The conclusion are summerized as follows: 1. When the component is subjected to a constant amplitude cyclic tensile loading, the welding residual stress is reduced as stress ratio increase. 2. As the fatigue crack is propagation through the compressive residual stress field, it was found that the effects of welding compressive residual stress on fatigue crack growth in weldments, and the stress ratio decreases, become larger and delay the fatigue crack growth rate. 3. For negative values of the effective stress ratio, R? in the welding compressive residual stress field, the prediction of fatigue crack growth rate by the Forman's equation were found to be corresponded to experimental data for stress ratio R?0.3, as the effective stress ratio R? approached zero, when the stress ratio R>0.3 the prediction of the fatigue crack growth rate by Forman's equation were found to be impossible.

This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.

최대/최소 경계 스키마 추출 기법을 이용한 XML 문서의 DTD 추출

박경현,최은선,이종연,박정석,류근호 충북대학교 컴퓨터정보통신 연구소 2000 컴퓨터정보통신연구 Vol.8 No.2

XML이 인터넷상의 데이터 교환의 표준으로 대두되면서 데이터 모델이나 플랫폼에 관계없이 데이터의 전송이 가능하게 되었다. 특히 데이터 중심의 XML 문서의 경우 전송시의 부하를 줄이기 위해 DTD없이 전송되는 경우가 일반적이다. 그러한 이유로 전송받은 XML 데이터의 저장 효율을 높이고 질의를 최적화하며 사용자에게 편의성을 제공해주기 위해서는 XML 데이터로부터 DTD 추출이 필수적으로 요구된다. 이 논문에서는 이러한 DTD를 추출하기 위해 반구조적 데이터의 스키마 추출 기법을 적용한다. 특히, 반구조적 데이터의 최소 경계 스키마를 추출하는데 데이터로그를 이용하는 기존의 방법보다 효율적인 방법인 시뮬레이션을 적용함으로써 보다 향상된 DTD 추출 기법을 제시한다. XML makes it possible for data to be exchanged regardless of the data model in which it is represented or the platform on which it is stored, serving as a standard for data exchange format on the internet. Especially, It is natural to send XML data without DTD on the internet when XML is data-centric XML. Therefore it is needed to extract DTD to store XML data efficiently, to optimize queries, and to help users browse XML data. In this paper, Techniques for upper/lower bound schema extraction are applied to extract DTD from XML data. Especially we propose an efficient technique for extracting DTD by using simulation which is better than datalog as a lower bound schema extraction method.

<P>Identical patterns and characteristics of sub-100 nm TiO2-based memristive systems on 4 inch silicon substrates were demonstrated using Step and flash imprint lithography (SFIL). SFIL is a nanoimprint lithography technique that offers the advantagess of a high aspect-ratio, reliable nano-patterns, and a transparent stamp that can be used to facilitate overlay techniques. The overlay process from the alignment system in IMPRIO 100 was appropriate for the fabrication of nanoscale crossbar arrays in this study. High-density crossbar arrays that consisted of TiO2 resistive switching material that was sandwiched between Pt electrodes with a width of 80 nm and a half-pitch of 100 nm were in turn replicated through successive imprinting and etching processes. The use of the direct metal etching process enhanced the uniformity of the TiO2/Pt interface. The electrical property of the crossbar arrays showed the bipolar switching behavior that resulted in the application of the nonvolatile resistive memory.</P>
