  • 세계 10대 도시이며 Metro City인 서울특별시는 인쇄, 봉제, 기계금속 등 전통적인 도심제조업이 분포되어있다. 이들 제조업은 세부 업종 및 공정에 따라 소상공인 집적지를 형성해 서로 상부상조 하는 형태로 발전해왔다. 집적지의 특성상 집적지 내 각 공정별 업체 간 물류는 신속히 이루어지고 있으나 상대적으로 영세한 소상공인이 최종 단계의 완제품 수요자에 대한 주문처리 서비스를 준비하기에는 어려운 현실이다. 따라서 원활한 수주, 배송처리를 위해 집적지 상공인을 위한 통합수주 Fulfillment Service Platform 도입이 시급하다. 본 논문에서는 전통 도심산업 중 인쇄업 소상공인의 기존 Fulfillment Service data를 수집, 분석하고 CRNN, k-NN, ID3 Decision Tree algorithm을 적용한 인공지능 Fulfillment Service Platform 시스템을 설계한다. 본 연구를 통하여 집적지 소상공인 누구나 활용할 수 있는 개별 수주, 배송 맞춤서비스 사용이 가능하게 함으로써 소상공인 매출 증대 및 역량 향상에 크게 기여할 것으로 기대한다.

  • This study conducted wide-tank experiments and numerical calculations for a vessel in various positions such as upright and inclined by 2 and 4 degrees, with the goal of investigating the motion amplitude response of a small damaged fishing boat subject to a beam sea. Numerical calculations were conducted based on the three-dimensional source distribution method. The good agreement of the numerical calculation and experimental results confirmed that the present calculation method can be efficiently used for the initial design of a small fishing boat. In addition, while the chine-line type has been frequently adopted to improve a ship's resistance performance in the design of a small fishing boat, it is considered that the possibility of a deterioration in rolling performance should be thoroughly considered.

  • Tidal flats are well developed in and around the Yellow Sea of Northeast Asia, and benthic diatoms are the most important primary producers in corresponding habitats. In the present study, the taxonomy and distribution of small negligible diatom species from Northeast Asian tidal flats are investigated for better understanding of the diversity of Korean marine benthic diatoms. The presence of Plagiogrammopsis minima and Diploneis aestuarii, which may have been ignored and/or misidentified due to their small size, were identified by both means of light microscopy (LM) and scanning electron microscopy (SEM). Plagiogrammopsis minima has never been reported from Korea before the present study, while Diploneis aestuarii was only once mentioned without any photographic information. Accordingly, we provide the morphological characteristics of the two species in detail with LM and SEM observation. Information on the regional distribution of the two species is also provided. Results of the present study contribute to the better understanding of the biodiversity of the Korean marine benthic diatoms.

  • We shall propose several estimators for the scale parameter in the uniform distribution when the parameter is functions of a known exposure level, and obtain expectations and variances for their proposed estimators. And we shall compare numerically relative efficiencies for proposed estimators of the scale parameter in the small sample sizes.

  • Background: Maspin (mammary serine protease inhibitor) is a member of the serpin superfamily. A few studies have examined the role of maspin in tumor suppression of non-small cell lung cancer (NSCLC); however, its role in the development and progression of NSCLC still remains controversial. We evaluated the immunohistochemical expression of maspin in order to elucidate its clinical significance in NSCLC. Methods: We analyzed 145 patients with pathologically confirmed NSCLC, including 66 cases of squamous cell carcinomas (SCCs) and 79 cases of adenocarcinomas (ADCs). We performed a immuno-histochemical stain with maspin and PCNA (proliferating cell nuclear antigen) using tissue microarray blocks. Results: There were 108 men and 37 women in the study population. The mean age of patients in the study was 63.7 years (range, 40.0~82.0; median, 65.0). The proportion of maspin expression was significantly higher in SCCs (52/66, 78.8%; p<0.01) than in ADCs (17/79, 21.5%; p<0.01). Maspin expression was not associated with PCNA (p=0.828), lymph node involvement (p=0.483), or tumor stage (p=0.216), but showed correlation with well-to-moderate tumor differentiation (p=0.012). There was no observed correlation between maspin expression and survival with NSCLC (p=0.218). Conclusion: The present study suggests that maspin expression was significantly higher in SCCs than in ADCs and was associated with low histological grade. However, maspin expression was not an independent factor to predict a prognosis in NSCLC.

  • The temporal dark image sticking phenomena for both the face-to-face and coplanar sustain electrode structures were compared. For both structures, the temporal dark image sticking phenomena were examined by measuring the difference in the IR emission, display luminance, perceived luminance, and temperature between the image sticking and the no image sticking cells. For the face-to-face structure, the 10-min sustain discharge causes a small increment of the panel temperature thanks to the ITO-less electrode structure, thereby resulting in mitigating the temporal dark image sticking phenomenon.

  • Purpose: Although there is a lot of secondary data available for comparing community health status and planning health policies in terms of large area such as metropolitan cities or provinces, there is restricted data for establishing community health policies of the small areas such as towns, Gun(i.e., districts), and Gu. Specifically, the problems of producing a valuable index for health promotion in small areas are three fold: First, there is not an appropriate index model for measuring a small community health status. Second, a large part of secondary data in the small areas has been produced in an irregular time interval. In addition, all valuable data can not be integrated without time consuming work. Thus this study tries to establish a health promotion index model for assisting community health promotion initiatives of local governments. Methods and materials: Literature review, community health specialist consultation and a questionnaire survey was performed. Results: Based on Dever's model, a prototype of health promotion indicators was proposed and modified by the community health specialists. 15 classification scheme of statistical yearbook reorganized into the six areas. Those six areas were comprised in 24 indicator class with 96 specific indicators. Through further modification processes by a questionnaire survey, we developed a health promotion indicator model that contains six areas with 23 indicator class encompassed by 87 specific indicators. Conclusions: This study proposed a model of health promotion indicator comprised in the six areas with 23 indicator classes for measuring small area health promotion status. However, more specific or additional data in human biology, environment, and socioeconomic data is essential for producing a stronger model for health promotion measurement.

  • A tidal prism eutrophication model, an one-dimensional intertidal model, is developed to study water quality conditions at small coastal basins and tidal creeks. The model simulates the physical transport processes using the concept of tidal flushing. The concept is simple and straightforward, and thus is ideal for small coastal basins with complex geometry. The model, having twenty-four state variables in the water column, simulates salinity, temperature, dissolved oxygen, three algal groups, and the cycles of carbon, nitrogen, phosphorus and silica. The model is applied to the Lynnhaven Bay, a small coastal basin of Chesapeake Bay in U.S.A. The model is calibrated using the field data collected in 1994, and then is verified using the independently collected data in 1980. The model overall gives a good reproduction of the field data, partly owing to the data collected from the field surveys specifically designed for the model application. This paper presents the procedure, and the results of the model calibration and verification.
