The research aims to find implications of machine learning and urban big data as a way to construct the flexible transportation network system of smart city by responding the urban context changes. This research deals with a problem that existing a bus headway model is difficult to respond urban situations in real-time. Therefore, utilizing the urban big data and machine learning prototyping tool in weathers, traffics, and bus statues, this research presents a flexible headway model to predict bus delay and analyze the result. The prototyping model is composed by real-time data of buses. The data is gathered through public data portals and real time Application Program Interface (API) by the government. These data are fundamental resources to organize interval pattern models of bus operations as traffic environment factors (road speeds, station conditions, weathers, and bus information of operating in real-time). The prototyping model is implemented by the machine learning tool (RapidMiner Studio) and conducted several tests for bus delays prediction according to specific circumstances. As a result, possibilities of transportation system are discussed for promoting the urban efficiency and the citizens’ convenience by responding to urban conditions.

Currently, museums and architectural heritage provide augmented user experiences by incorporating various media technologies. They still, however, suffer from the limitation of entertainment-based and the provision of location-based simple and repetitive contents. In addition, while acting as a key medium of experience for architectural heritage, the concept of space is not properly reflected in current services. The purpose of this study is to design user space experience considering such characteristics of architectural heritage. The spatial experience content and content production platform are defined. This software platform creates content that enhances the experience of the place by giving a context-based digital data associated with space and objects. The spatial experience content is designed as a series of experience sequences. The composition of the sequence borrows the method of film and narrative which segment and connect consecutive experiences on a scene basis considering user "s detailed spatial experience. Therefore, content components can be combined and reproduced in various types. Augmented contents were extracted by using rule-based reasoning function of ontology at the moment. As a practical example of architectural heritage, the Seokjojeon Hall is used to reveal a spatial experience scenario.

목적 비만은 체내 비타민 D의 농도와 연관되어 있는 것으로 알려져 있다. 이에 폐경 여성의 혈중 비타민 D 농도와 체질량지수로 평가한 비만과 의 상관관계를 알아보고자 한다. 연구방법 혈중 비타민 D 농도와 비만과의 관계를 알아보기 위해 본 연구는 2005년 1월부터 2011년 3월까지 310명의 건강한 폐경 여성을 대상으로 혈중 25hydroxy vitamin D 농도와 체질량지수로 비만도를 측정하고, 골밀도, 골표지자 및 부갑상선 호르몬 농도와 같은 골건강 지표들을 측정하였다. 혈중 비타민 D 부족의 기준을 30ng/mL, 20ng/mL로 각각 나누어 체질량지수를 비롯한 각종 변수들과의 상관관계를 분석하였다. 결과 혈중 비타민 D 부족을 30ng/mL 기준으로 하였을 때 98.9%가, 20ng/mL를 기준으로 하였을 때 87.8%가 비타민 D 결핍증을 보였다. 연령, 신장, 체중, 골밀도, 골표지자 모두 비타민 D 농도와 유의한 상관관계를 보이지 않았고 부갑상선 호르몬 농도는 혈중 비타민 D 농도와 음의 상관관계를 보였다. 체질량지수는 비타민 D와 음의 상관관계를, 부갑상선 호르몬 농도와 양의 상관관계를 보였으나, 통계적으로 유 의하지 않았다. 결론 폐경 여성 중 약 87.8%-98.9%인 대다수 여성이 비타민 D 부족상태를 보이며 혈중 비타민 D 농도와 체질량지수 사이에 유의한 상관관계 는 없었다. Objective Obesity is associated with alterations in vitamin D (VtD) system. We evaluated the correlation between VtD level and body mass index (BMI), a standard for the evaluation of obesity in postmenopausal women. Methods To study the relationship between VtD levels and obesity, we recruited 310 healthy postmenopausal women between January 2005 and March 2011 and analyzed the correlation between BMI and serum 25-hydroxyvitamin D (25-OH-VtD) level. We also analyzed the relationship between serum VtD level and bone health status such as bone mineral density measured by dual-energy X-ray absorptiometry, bone turnover marker, and parathyroid hormone (PTH), Results With a cut-off level for VtD deficiency at 30ng/mL, 98.9% patients showed a VtD deficiency, while 87.8% patients showed a vitamin D defi ciency with a 20-ng/mL cut-off level. VtD levels had no signifi cant correlation with age, height, weight, BMI, or bone turnover markers. PTH level and serum 25-OH-VtD level showed a negative correlation, VtD level showed negative correlation with BMI, but statistically not signifi cant. Conclusion In this study, most of postmenopausal women (more than 87.8%) had a VtD defi ciency, and VtD level showed negative correlation with BMI, but was not statistically signifi cant.

장선영(Sun-Young Jang),정승현(Seunghyun Jung) 한국산학기술학회 2021 한국산학기술학회논문지 Vol.22 No.3

연구동향은 시기별 연구주제에 대한 중요도 판단과 부족한 연구 분야를 파악하고 신규 분야를 발굴하는데 유용하게 활용될 수 있다. 본 연구에서는 인구집중과 도시화로 인해 다양한 문제가 발생하고 있는 도시공간을 대상으로 한 논문들을 대상으로 시기별 연구동향을 분석하였다. 이를 위해 2002년부터 2019년 사이에 게재된 한국학술지인용색인 (KCI)에 등재된 논문의 초록을 대상으로 데이터마이닝 기법 중 하나인 토픽모델링 분석을 수행하였다. 토픽모델링은 전체 내용에서 일정한 패턴을 발견해낼 수 있는 알고리즘 기반의 텍스트마이닝 기법으로 방대한 문헌에서 주제를 찾아내고 군집하는데 용이하다. 본 연구에서는 키워드 빈도, 연도별 경향, 토픽 도출, 토픽별 군집, 토픽유형별 경향에 대한 분석을 실시하였다. 그 결과 먼저 도시재생 분야연구가 지속적으로 증가되고 있고 앞으로도 세부 주제가 확대될 수 있는 분야로 분석되었다. 그리고 도시재생 주제는 이제 정규 연구분야로 자리 잡고 있는 것으로 파악되었다. 반면, 개발/성장과 에너지/환경과 같은 주제는 정체기에 들어간 것으로 분석되었다. 본 연구는 국내 전체 도시분야 연구를 대상으로 데이터마이닝 기법인 토픽모델링을 이용하여 키워드 간 연관성과 경향을 함께 분석하였다는 데 의의가 있다. Research trends can be usefully used to determine the importance of research topics by period, identify insufficient research fields, and discover new fields. In this study, research trends of urban spaces, where various problems are occurring due to population concentration and urbanization, were analyzed by topic modeling. The analysis target was the abstracts of papers listed in the Korea Citation Index (KCI) published between 2002 and 2019. Topic modeling is an algorithm-based text mining technique that can discover a certain pattern in the entire content, and it is easy to cluster. In this study, the frequency of keywords, trends by year, topic derivation, cluster by topic, and trend by topic type were analyzed. Research in urban regeneration is increasing continuously, and it was analyzed as a field where detailed topics could be expanded in the future. Furthermore, urban regeneration is now becoming a regular research field. On the other hand, topics related to development/growth and energy/environment have entered a stagnation period. This study is meaningful because the correlation and trends between keywords were analyzed using topic modeling targeting all domestic urban studies.

장선영(Sun-Young Jang),김두식(Dusik Kim) 한국산학기술학회 2021 한국산학기술학회논문지 Vol.22 No.1

스마트시티의 성공을 위한 주요한 전략 중 하나로 시민참여와 리빙랩이 주목받고 있다. 리빙랩은 기술의 최종 사용자인 시민들이 문제를 정의하고 해결하기 위한 대안의 탐색에 참여하며, 순환적 과정으로 대안을 검증하기 위한 실험을 반복한다. 본 연구의 목적은 도시문제 개선을 위한 시민참여형 온라인 커뮤니티 플랫폼의 운영모델을 제시하고, 이를 구현 및 테스트하여 활용 가능성을 확인하는 것이다. 이를 위해 도시문제 개선을 위한 시민참여형 온라인 커뮤니티 플랫폼의 운영모델을 제시하고, 운영모델이 추구하는 기능이 반영될 수 있도록 온라인 플랫폼을 설계 및 구현하였다. 최종적으로 경기도 고양시 일산서구 소재 오마초등학교를 사례로 하여 기능에 대한 파일럿 테스트를 수행하였다. 본 연구에서 제시한 운영모델은 도시의 여러 문제가 밀집될 수 있는 보행환경과 위험 환경에 취약한 어린이를 염두에 두고 계획되었다. 결과적으로 참여자들 간에 도시문제 사례의 공유와 이에 대한 의사소통이 이루어지는 것을 통해 커뮤니티 플랫폼의 활용 가능성을 확인하였다. 커뮤니티 플랫폼의 관리자는 위치정보를 기반으로 사용자가 게시한 도시문제 사례를 지도로 가시화하여 볼 수 있었으며, 이를 히트 맵 형식으로 가시화함으로써 도시문제가 밀집된 위치들을 파악할 수 있었다. Citizen participation and Living Lab are attracting interest as one of the major strategies for the success of smart cities. In a Living Lab, citizens, who are the end-users of technology, participate in the search for alternatives to define and solve problems and repeat experiments to verify alternatives in a circular process. The purpose of this research was to present an operating model of a citizen-participating online community platform to improve urban problems, implement and test it, and show its applicability. To this end, an operation model of a citizen-participating online community platform was proposed to improve urban problems. An online platform was designed and implemented to reflect the functions pursued by the operation model. Finally, a pilot test for the function was performed using the Oma Elementary School case located in Ilsan, Goyang-si, Gyeonggi-do. The operating model was designed with the city"s pedestrian environment and children. As a result, the sharing and communicating process of urban issues among community members worked appropriately according to the designed intention. The Living Lab coordinator could visualize and view urban issues posted by users on a map based on location information. Visualizing the urban problem as a heat map confirmed that urban problems were concentrated in a specific area.

Data were obtained from 230 adult male and female consumers living in Busan who have traveled overseas in the last year, and were analyzed by factor analysis, Cronbach"s alpha test, t-test, and chi-square test, using SPSS by WIN 12.0. The results of this study were as follows: First, purchasing situation that affected impulse buying of overseas travelers consisted of Price/brand situation, Mood/affection situation, Store atmosphere situation, Memorial situation, and Others" recommendation situation. Perceived risk of overseas travelers were composed of Appropriateness/comfortableness risk, Fashion/prestige risk, and Economic risk. The preferred store types of overseas travelers were Duty free shops and Department stores. Second, overseas travelers were more likely to buy impulsively fashion products which were famous brands and less expensive than domestic price. They also bought those items when they were in good mood, were affected by store atmosphere, others‘ recommendation, and perceived as a memorial product. There were no significant differences in perceived risk factors between impulse buyers and non-impulse buyers, although both groups were highly perceived risks appropriateness and comfortableness or of their images. Overseas travelers visited most frequently duty free shops to buy fashion products. Impulse buyers of overseas travelers were more likely to visit department stores and shopping mall than non-impulse buyers. Finally, there are differences in purchasing situations and store types to buy fashion products between impulse buyers and non-impulse buyers of overseas travelers. This study could provide managerial implications for developing strategies fashion products related to overseas traveling.

조선시기 流刑와 絶島定配의 推移

장선영(Jang Sun-Young) 역사문화학회 2001 지방사와 지방문화 Vol.4 No.2

This study is to examine the change of status of islands through the analysis of place of exile. That is, it investigates the proportion of exile to the island among the whole places of exile and the shift of exile to the island and then explains the change of status of the islands. For the analysis, it extracts 5,860 articles related to exile from 「The History of the Chosun Dynasty: Chosun Wangjo Shilrok」. The period extracted is from the construction of Choson Dynasty to 1896 when banishment system was changed into prison term system from distance system. Banishment was divided into Exile 2 thousand ri, Exile 2.5 thousand ri and Exile 3 thousand ri according to the distance, and into confinement, detention and exile according to the gravity of the offense. Total 408 places were used for the place of exile. The places of exile were mainly distributed at coastal area, island and northern edges. The frequency of exile shows the similar distribution to the place of exile. Chollado shows the most frequent exiles, followed by Kyungsangdo. In the frequency of exiles by period, it exceeded 900 times in early Chosun Dynasty, but it was greatly reduced to 103 times in 1551-1600. But it was increased again to 1,018 times in 1751-1800. According to the features by the period shown in the change of frequency, first high frequency of 1751-1800 was because the central control was strengthened due to the political stability and the punishment system was strictly applied. Second, high frequency of 1392-1500 was because there were many exiles of the persons related to the former dynasty due to the establishment of a new dynasty and there was the War of Prince S. Third, the frequency of exile was reduced in the period of King Sun Jo and it is because the materials related were lost due to Japanese Invasion of Korea in 1592. The exile to the island was designated by the nation. It was Cheju, Daejung, Jungeui, Jindo, Geojae and Namhae during the period of King Gwang Hae Gun. But, it was increased in late Choson Dynasty, that is, it included Gokumdo in King Hyun Jong, Gumkabdo, Nokdo, Heuksando, Gogunsando, Weedo and Baekryungdo during the period of King Suk Jong, Narodo, Sado, Shiniido, Jido and Chujado during the period of King Jung Jong, Yeodo in King Young Jo, Godolsan in King Jung Jo and Imjado during the period of King Sun Jong. The increase of the exile to the island was peak during the period of King Suk Jong. The exile to the island was distributed at the West Coast and South Coast and it was noticeable that newly added islands in late Choson Dynasty were all in Chollado. The reason of the increase of exile to the island in late Yi Dynasty was the increasing frequency of exile. Therefore the government substituted it with the island which has good conditions as the place of exile and then the number of exile to the island was increased greatly. But, there was a requirement for the selection of the exile to the island. First it should be controlled by government and has the economic ability responsible for the livelihood of the criminal. It means the island was changed into the place for accommodating the people.
