  • 2017년 12월 기준 우리나라에 등록된 자동차는 약 2,200만 이상으로, 그 증가율은 매년 증가하는 추세이다. 이러한 최근 차량대수 및 고자산인 외산차 보유율 증가는 자연재난에서 노출과 관련한 위험도를 증가시키는 주요인이 되며, 홍수발생 시 상당한 규모의 경제적 피해를 야기한다. 현재 국가연구개발사업으로 진행 중인 행정안전부(2017) 연구는 위험지역 내 차량의 공간적 분포와 차량유형별 침수심에 따른 취약성을 고려하여 어떠한 홍수사상으로부터 예상되는 차량 피해액을 추정하는 방법을 제시한 바 있다. 여기서는 어떠한 집계구 내에서 동일한 침수심 구간을 가지는 면(polygon)을 분석단위로 하고 있는 데, 이를 편의성 차원에서 벡터자료에 기반 한 연산과정을 수행할 경우 정의된 침수구역도(재해정보)의 고유 정보가 훼손되거나, 세분화된 침수심 구간에 따른 손상률 관계를 사용할 수 없는 문제점이 있다. 이에 본 연구에서는 격자 기반의 침수구역도와 인벤토리 지도로부터 Raster GIS 공간연산을 활용한 차량피해 산정절차를 제시하였고, 이를 신천수계 하천기본계획(경기도, 2011)에서 계획된 치수사업에 적용하여 홍수빈도별 사업시행 전후 상황에 적용하였다. 이 과정에서 침수구역도는 인벤토리 상의 집계구 면적을 고려하여 $5m{\times}5m$ 크기로 제작하였고, 동일한 격자크기로 변환된 인벤토리는 변환 전후 면적을 기준으로 할 때 거의 오차가 없는 것으로 확인되었다. 그리고 Raster 공간연산으로부터 침수편입률을 결정하는 과정에서 집계구 넘버 및 침수심 정보를 확인하기 위한 자료별 전처리 과정을 제시하였고, 여기서 집계구 넘버는 인벤토리 정보와 침수심 정보는 손상함수와 연계된다. 본 연구에서 제시한 결과는 향후 실무에서 직접 적용하는 데 활용하기 위하여 방법론과 함께 가이드라인 문서로 정리할 계획이다.

  • I conducted empirical analyses of what happens when an offline channel expands to an online channel and whether the pre-existing offline channel's competitive assets (e.g. brand reputation and level of service satisfaction) can be linked to online channel preference. I found that an offline channel's brand reputation and level of service satisfaction can have a direct influence on offline channel preference and a second-hand influence on online channel preference. Thus, if the competitiveness of the online channel is strong enough and its customers have a higher preference for the offline channel, they will be committed and loyal to the company. The resultant enhanced competitiveness of the offline channel will present opportunities for both present and future success. The main results are the following. First, the management of the distribution channel service quality is more important than that of the brand reputation. Customers' experiences of service and subjective evaluations are not important only as the leading factors in the long-term brand reputation management but also as influential factors in channel preference. SoThus, given that the service quality of the pre-existing channel is not the customers' main concern, a strategy of improving the level of service satisfaction aimed at present customers is more valuable than a wide brand positioning strategy aimed at general and new customers. Second, when an offline channel company establishes an internet shopping mall on an online channel, it is highly likely that the preference and subjective evaluation of the present customers will influence the online channel. This applies not only to the special case of an expansion from an offline intermediary channel to an online one, but also to an online channel acting as an expansion of the business model of a conventional manufacturing or service company: both cases are vertical integrations of marketing channels in an expansion of the distribution channel. My theory applies to a wide range of contexts. Third and finally, any business strategy can grasp the meaning of 'channel expansion. Fundamentally, it is an expansion of the sales activity channel and marketing activity. However, it is also a way of enhancing marketing and sales competitiveness through an expansion to an online or offline channel. The expansion of an offline company to an online channel could be seen not as improvement but as an innovation of the business process by which two goals are achieved with one technique. The former is expected to increase the sales of the offline company, and the latter is also expected to increase sales while also contributing to cost reduction.

  • This study was conducted to compare of greenhouse gas emissions between 1996 and 2006 IPCC (Intergovernmental Panel on Climate Change) guidelines change. Greenhouse gas emissions were calculated separately by rice cultivation, agricultural soils and field burning of agricultural residues from 2000 to 2008 according to 1996 and 2006 IPCC guidelines. To calculate greenhouse gas emissions, emission factor and activity data were used IPCC default value and the food, agricultural, forestry and fisheries statistical yearbook of MIFAFF (Ministry for Food, Agriculture, Forestry, and Fisheries). The greenhouse emissions by 1996 IPCC guidelines were highest in rice cultivation as 4,008 $CO_2$-eq Gg of 2000 and 3,558 $CO_2$-eq Gg of 2008. The emissions by N-fixing crops, crop residues returned soils and field burning did not much affect the total emissions. $CO_2$ emissions by urea and lime were calculated by adding in 2006 IPCC guidelines and its emissions were 157 and 82 $CO_2$-eq Gg in 2008 respectively. The emissions by N-fixing crops, crop residues returned to soils and field burning, in common with 1996 IPCC guidelines, did not have a significant impact on total emissions. The total emissions in agronomic sector was decreased continuously from 2000 to 2008 and annual emissions by 2006 IPCC guidelines were approximately 26-29% less than the 1996 IPCC guidelines.

  • Cardio-cerebrovascular diseases (CCD) account for 24% of the causes of death to Koreans and its proportion is the highest except cancer. Currently, the risk of the cardiovascular disease for domestic patients is based on the Framingham risk score (FRS), but accuracy tends to decrease because it is a foreign guideline. Also, it can't score the risk of cerebrovascular disease. CCD is hard to predict, because it is difficult to analyze the features of early symptoms for prevention. Therefore, proper prediction method for Koreans is needed. The purpose of this paper is validating IG-MLP (Information Gain - Multilayer Perceptron) evaluation based feature selection method using CCD data with simulation. The proposed method uses the raw data of the 4th ~ 7th of The Korea National Health and Nutrition Examination Survey (KNHANES). To select the important feature of CCD, analysis on the attributes using IG-MLP are processed, finally CCD prediction ANN model using optimize feature set is provided. Proposed method can find important features of CCD prediction of Koreans, and ANN model could predict more accurate CCD for Koreans.

  • This study was conducted to establish mosquito distribution density and habitat in Sejong city for the prevention of mosquito-borne infectious diseases. The overall distribution of mosquitoes in the Sejong City was investigated, and the population density of mosquitoes in the old and new city was analyzed. Mosquito populations were determined using MOSHOLE and Blacklight traps once a week overnight. We also compared the mosquito population density of the old city and the new city, and the daily mosquito population was calculated using the data from the smart mosquito trap(DMS). Of all the study sites, Geumnam-myeon had the highest number of mosquitoes captured, and the dominant species were Armigeres subalbatus and Culex pipienspallens. Mosquito species with the potential for transmitting diseases were mainly found in Yeonseo-myeon (106 individual), and Geumnam-myeon (101). Mosquito collection rates by MOSHOLE trap and Blacklight trap were 58.49% and 41.51%, respectively. We concluded that using CO2 would be the most suitable approach for collecting mosquitoes. The mosquito population density in the old city (92.05±7.04) was approximately twice that of the new city(51.50±4.05). Since Sejong City is divided into old city and new city, it is difficult to spot remarkable effects in a standardized way. For effective quarantine, differentiation of quarantine must be established. This study results provide a basis for Sejong City's integrated mosquito control guidelines, and therefore effective control of which we believe will help control the spread of mosquito-borne diseases and reduce damage from mosquitoes.

  • 쇼핑, 음악, 영화 등 오프라인에서 즐기던 많은 서비스가 이제는 온라인화 되어 일상화되었다. 그 중 뉴스의 경우도 미국의 리서치업체가 조사한 결과에 따르면, 인터넷 사용자의 21%가 온라인 뉴스를 오프라인보다 더 선호할 뿐만 아니라 온라인에 대한 선호도가 비약적으로 늘고 있다고 밝혔다. 종이 페이퍼로 뉴스를 제공할 때는 정보를 제공하는 공간이 제한적이기 때문에 사용자의 행위를 어느 정도 예상할 수 있다. 그러나 상대적으로 온라인 뉴스와 같은 컨텐츠 서비스는 하이퍼텍스트를 기본으로 하기 때문에 사용자의 패턴을 정확히 파악하기가 쉽지 않다. 컨텐츠 서비스 사용 행위를 분석하기 위해 아이트랙킹, 인뎁스인터뷰 등 여러 방법론을 적용할 수 있으며, 아이트랙킹 연구는 Poynter Institute 에서 2004년도에 진행한 사례가 있지만 여전히 컨텐츠 서비스에서의 핵심 이슈인 컨텐츠 영역에 대한 관심도, 영역별 연관성 파악 등에 대한 객관적 데이터가 부족하다. 따라서 본 논문은 컨텐츠 서비스 사용자의 유저 시나리오 도출을 위해 온라인 뉴스를 대상으로 한 분석 케이스를 소개한다. 본 사용자 행동 분석 리서치 수행을 위해 원격툴을 개발하였으며, 이 툴을 실제로 적용해봄으로써 컨텐츠 서비스 분석시 가능성과 고려사항들을 함께 살펴본다.

  • 최근 제조업체들은 비핵심업무인 물류관련 업무를 전문 업체에 위탁하는 물류 아웃소싱을 하고 있다. 이를 통해 기업들은 제품개발과 마케팅에 기업의 핵심역량을 집중하고, 물류 관련 비용을 절감하고 고객 서비스 수준을 제고할 수 있게 되었다. 최근에는 물류 아웃소싱이 파트너쉽을 바탕으로 한 공동소싱으로 발전되어가는 추세에 있다. 물류아웃소싱에 대한 사례연구는 향후 제조업체들이 물류아웃소싱을 하기 위한 전략을 수립하는데 있어서 좋은 가이드라인을 제시할 것으로 생각한다. 본 연구는 글로벌 물류기업인 UPS와 삼성전기 간의 4자물류 아웃소싱(4PL) 사례를 통해 4PL을 이해하고, 이와 관련된 주요 이슈를 파악하여 기업들이 물류아웃소싱을 하기 위한 협력 전략을 수립하는데 가이드라인을 제시하는데 목적이 있다. 사례의 내용은 먼저 삼성전기와 UPS간의 물류 아웃소싱 추진배경과 진행과정을 살펴보았다. 그리고 물류 아웃소싱 과정에서 발생한 문제들을 조직차원의 문제, 경영진의 단기적인 안목, 양사의 문화적 차이, 정보시스템의 통합, 그리고 성과에 대한 인식 차이 등 5가지 차원에서 살펴보았다. 본 연구에서 파악한 주요이슈들 측면에서 살펴본다면 물류 전문업체와 아웃소싱을 하고자 하는 제조기업들에게 많은 시사점을 제공할 수 있을 것으로 기대된다.

  • On-line handwritten character recognition be achieved successful results since effectively neural networks divided the letter which is the time ordering of strokes and stroke position. But off-line handwritten character recognition is in difficulty of incomplete preprocessing because has not information of motion or time and has frequently overlap of the letter and many noise occurrence. consequently off-line handwritten character recognition needs study of various methods. This paper apply watershed algorithm to preprocessing for off-line handwritten hangul character recognition. This paper presents effective method in four steps in watershed algorithm as consider execution time of watershed algorithm and quality of result image. As apply watershed algorithm with effective structure to preprocessing, can get to the good result of image enhancement and binarization. In this experiment, this paper is estimate the previous method with this paper method for execution time and quality in image. Average execution time on the previous method is 2.16 second and Average execution time on this paper method is 1.72 second. While this paper method is remove noise effectively with overlap stroke, the previous method does not seem to be remove noise effectively with overlap stroke.
