주민의 공원녹지의식에 따른 도시공원녹지확충 연구 : 수원시의 공원녹지사례 중심으로

박청인(Park Chung-In) 한국산림휴양학회 2010 한국산림휴양학회지 Vol.14 No.3

본 연구는 도시공원녹지의 확충에 대하여 수요자인 주민의 공원녹지에 대한 의식을 반영한 계획이 모색될 수 있도록 기초적 자료구축에 목적이 있다. 기초적 자료는 주민이 공원녹지에 대한 기본적 개념, 이용행태, 정책참여의사등으로 도시공원녹지 전반에 대한 주민의 평가를 분석함으로서 구축되었다. 학문적으로는 공원녹지계획의 상향식 계획의 요인과 도시공원녹지에 대한 이용자 특성 연구의 근거이론 구축에 부가적 목적을 두고 있다. 수원시를 연구대상지로 하여 총 733인의 표본의 추출로 면접조사가 이루어진 결과, 아래와 같은 연구의 결과를 얻었다. 수원시공원녹지는 산책과 휴식을 위하여 가족이용자가 가장 많았으며 주로 이용되는 시설은 근린공원과 체육시설지로 분석되었다. 공원녹지에 대한 평가는 도시전체의 환경적 질의 관점이 아니라 주민의 개개인의 삶의 질의 관점에서 평가하였고, 정책당국의 공원녹지정책에는 경제적 참여보다는 행동적 참여를 더 지지하였다. 결론적으로 공원녹지의 확충은 주민의 의견이 반영되는 상향식 의사결정에 의한 방법이 더욱 더 모색되어야 할 것이다. This study aims to establish ground theory and database for expansion of urban park and green belt based on residents’ attitude. The residents’ attitude of park and green belt was evaluated by various factors such as basic concept of park, usage pattern, participation in city government policy. For this study, The interview method was applied to 733 individuals who were collected as the study sample. The results of the study are follows. Most of urban residents use neighborhood parks and sports complex for relaxation and strolling. The urban residents evaluated urban park and green belt by not a holistic thought of urban environment, but individual view of quality of life. The urban residents prefer to political and participational surport rather than financial support for city government policy of urban park and green belt. In conclusion, the expansion of urban park and green belt should be received a down-up decision making system for reflecting urban residents’ opinions.

Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade plantee and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

도시공원녹지의 구성과 배치 특성에 따른 이용만족도에 관한 연구 - 일본 타마뉴타운의 사례중심으로 -

염성진,박청인,Yeom, Sung-Jin,Park, Chung-In 한국조경학회 2011 韓國造景學會誌 Vol.39 No.5

도시에 있어서 공원녹지는 도시의 구조적, 사회적 환경을 개선하는 다양한 기능이 있다. 본 연구는 도시의 공원녹지계획이 도시환경의 개선에 관한 연구이다. 지금까지 도시에 있어서 공원녹지계획의 대부분은 녹지의 양의 증대를 목적으로 실시되어 왔다. 그러나 한정된 도시공간에서 공원녹지의 물리적인 확충은 토지의 확보가 어려워 곤란한 것이 현실이다. 그럼으로 본 연구에서는 기존의 공원녹지와 녹지에 대한 이용자평가를 통해 향후 공원녹지계획상의 학문적 근거이론의 확인과 실무적 사례 구축에 기여한다는 의의를 가진다. 본 연구에서는 공원녹지의 구성과 배치특성에 균등배치와 집약배치의 각기 다른 특성을 가진 일본의 타마뉴타운의 두 지구를 선택하여 319명의 주민에게 설문조사를 실시하여 t-검정, 요인분석, 중회귀분석의 통계방법을 활용하여 분석하였다. 연구의 결과로서 공원녹지의 구성과 배치가 다른 두 지구의 만족도평가요인은 차이가 확인되지 않았으나, 각 지구내의 세부평가요인에 있어서는 차이가 확인되었다. 만족도에 영향을 미치는 요인으로는 공원녹지의 질, 주변녹지의 질, 접근성, 차도분리의 요인이 두 지구의 공통요인인 것이 확인되었다. 공원녹지가 집약배치된 지구에서는 만족도평가요인에 있어서 주변녹지의 질이 만족도에 가장 큰 영향을 미치며, 공원녹지가 균등배치된 지구에서는 만족도평가요인에 있어서 공원녹지를 이용하는 보행공간의 차도분리가 만족도에 가장 큰 영향을 미치는 것이 확인되었다. Parks and green spaces have various functions for improving urban physical and social environments. Urban parks and green space planning have been applied in this study for the purpose of enhancing the urban environment. The most popular method for urban parks and green space planning is incrementing the quantity of parks and green spaces. However, it may not be possible to designate new parks and green spaces in a large city because of the difficulty of obtaining land. This study explores how urban parks and green space planning produces better quality urban environments without having to designate new parks and green spaces. The study evaluates existing parks and green spaces according to the satisfaction of the users. This evaluation could be a useful tool for those planning urban parks and green space systems. The study was performed in Tama Newtown, Japan, within two districts with two distinct characteristics of park systems: concentration and equality arrangement forms. For comparison, on-site questionnaires were used, with 319 residents in the area responding to the study. The data was collected and analyzed, using t-test, factor analysis, and multiple regression methods. The study found there was no difference in satisfaction factors be tween the two districts. However, differences were found within each of the districts, depending on parks and green space components. For example, the quality of green space was the most important factor for the district with a planned concentration arrangement form of parks and green spaces, but, separation of the pedestrian and vehicular systems was the most important factor in the district with a planned equality arrangement form of park system. Factors affecting the satisfaction of parks and green spaces that were common between the two sites were: accessibility, quality of park, quality of green space, and separation of pedestrian and vehicular traffics.

박청운(Chung-woon Park),박효섭(Hyo Sub Park) 한국항공우주학회 2017 韓國航空宇宙學會誌 Vol.45 No.5

본 논문은 기존의 시간 지연 데이터를 이용한 원격 측정 방법에서 생기는 무선 채널 비효율성을 증대시키기 위하며 주파수 효율적 재전송 방법을 제시하였다. 제시된 방법은 트리거 기반 메모리를 사용하여 주파수 효율적으로 데이터를 재전송한다. 이는 원격측정데이터를 수신하는 과정에서 다중경로페이딩이나 송신 안테나 패턴에 의해 영향 받는 통신환경 뿐 아니라 원격 측정 데이터를 송신하는 과정에서 이벤트에 의해 송신 환경에서 생기는 오류 데이터를 최소화한다. 비행시험 결과 데이터에서 주파수 효율적 재전송 데이터를 이용하여 원격측정의 성능 향상을 입증한다. Since the telemetry performance using the time-delayed data dissipates the wireless channel resources, we propose the spectral efficient retransmission scheme in this paper. In the proposed scheme, the telemetry data is retransmitted based on triggered memory to improve the spectral efficiency. The proposed scheme minimizes the error caused by multipath fading, antenna pattern as well as the error caused by the flight events. In the flight simulation data, we show the proposed scheme improves the telemetry performance based on spectral efficient retransmission.

박도형(Do-Hyung Park),정재권(Jaekwon Chung),정여진(Yeo Jin Chung),이동원(Dongwon Lee) 한국지능정보시스템학회 2014 지능정보연구 Vol.20 No.4

시장 예측은 일정 기간 동안 소비자에게 판매되는 동종 제품 또는 서비스의 수량 혹은 매출액의 규모를 추정하는 활동으로 정의할 수 있다. 정확한 시장 예측은 기업의 입장에서 새로운 제품의 도입시기 결정, 제품 설계, 생산계획 수립, 마케팅 전략 수립 등에 활용됨으로써 경영활동에 있어 효율적인 의사결정을 내릴 수 있게 하고, 정부의 입장에서는 발전 가능성이 있는 분야에 국가예산을 더 배분할 수 있는 효율적인 예산수립이 가능하게 한다. 본 연구는 정보통신기술(Information and Communication Technology: ICT) 분야의 제품 및 서비스에 대해서 과거의 시계열 자료를 이용하여 시장 성장곡선을 도출하고, 성장패턴이 비슷한 그룹으로 분류하여, 산업 내 시장에 대해 이해하고, 제품들의 미래 전망을 예측하는 데 목적이 있다. 다양한 아이템들을 통일되고 일관적인 방법으로 예측하기 위하여, 로지스틱 모형, 곰페르츠 모형, Bass 모형의 세 가지 전통적인 성장모형과 로지스틱 모형이나 곰페르츠 모형에서 도출되는 잠재시장 크기를 Bass 모형에 결합시킨 두 가지 하이브리드 성장모형을 개발하여 비교 분석하였다. 데이터 설명력이 우수한 로지스틱 + Bass 모형을 최적의 모형으로 선정하여 ICT 제품 및 서비스들 각각의 시장 성장곡선 모수를 확인하였다. 도출된 모수를 데이터로 하여, 자기조직화 지도 알고리즘을 통해, 5개의 의미 있는 영역으로 구분된 시장 성장패턴 지도가 구축되었는데, 각 영역별로 차별화된 특징과 성장패턴을 가지고 있었다. 본 연구에서 제안한 프로세스 및 시스템은 산업 시장 분석 시스템의 수요 예측 기능으로 활용될 수 있으며, ICT 산업뿐만 아니라 다양한 산업 및 분야에도 적용 가능할 것으로 기대된다. Market forecasting aims to estimate the sales volume of a product or service that is sold to consumers for a specific selling period. From the perspective of the enterprise, accurate market forecasting assists in determining the timing of new product introduction, product design, and establishing production plans and marketing strategies that enable a more efficient decision-making process. Moreover, accurate market forecasting enables governments to efficiently establish a national budget organization. This study aims to generate a market growth curve for ICT (information and communication technology) goods using past time series data; categorize products showing similar growth patterns; understand markets in the industry; and forecast the future outlook of such products. This study suggests the useful and meaningful process (or methodology) to identify the market growth pattern with quantitative growth model and data mining algorithm. The study employs the following methodology. At the first stage, past time series data are collected based on the target products or services of categorized industry. The data, such as the volume of sales and domestic consumption for a specific product or service, are collected from the relevant government ministry, the National Statistical Office, and other relevant government organizations. For collected data that may not be analyzed due to the lack of past data and the alteration of code names, data pre-processing work should be performed. At the second stage of this process, an optimal model for market forecasting should be selected. This model can be varied on the basis of the characteristics of each categorized industry. As this study is focused on the ICT industry, which has more frequent new technology appearances resulting in changes of the market structure, Logistic model, Gompertz model, and Bass model are selected. A hybrid model that combines different models can also be considered. The hybrid model considered for use in this study analyzes the size of the market potential through the Logistic and Gompertz models, and then the figures are used for the Bass model. The third stage of this process is to evaluate which model most accurately explains the data. In order to do this, the parameter should be estimated on the basis of the collected past time series data to generate the models’ predictive value and calculate the root-mean squared error (RMSE). The model that shows the lowest average RMSE value for every product type is considered as the best model. At the fourth stage of this process, based on the estimated parameter value generated by the best model, a market growth pattern map is constructed with self-organizing map algorithm. A self-organizing map is learning with market pattern parameters for all products or services as input data, and the products or services are organized into an N X N map. The number of clusters increase from 2 to M, depending on the characteristics of the nodes on the map. The clusters are divided into zones, and the clusters with the ability to provide the most meaningful explanation are selected. Based on the final selection of clusters, the boundaries between the nodes are selected and, ultimately, the market growth pattern map is completed. The last step is to determine the final characteristics of the clusters as well as the market growth curve. The average of the market growth pattern parameters in the clusters is taken to be a representative figure. Using this figure, a growth curve is drawn for each cluster, and their characteristics are analyzed. Also, taking into consideration the product types in each cluster, their characteristics can be qualitatively generated. We expect that the process and system that this paper suggests can be used as a tool for forecasting demand in the ICT and other industries.

박정(Chung Park) 한국교육평가학회 2008 교육평가연구 Vol.21 No.3

  본 연구는 교육관련 맥락 변인들이 각 능력집단별로 학업성취도에 어떻게 다르게 영향을 미치는지를 살펴본 것이다. 이를 위하여 수학ㆍ과학 성취도 국제비교 연구인 TIMSS 2003에서 수집된 학교와 학생 설문지 자료를 사용하여 2수준 다층 자료 분석을 실시하였다. 연구 결과, 전체집단을 대상으로 할 경우는 학교수준의 변인에서는 교사의 학생에 대한 기대정도, 교사의 연수정도, 동일 교육내용과 수준별 수업의 교육과정 운영방식, 그리고 학부모의 학교 참여 정도가 의미 있게 나타났고, 학생 수준에서는 진학기대, 수학적 효능감, 교과 가치, 독서시간, 과외여부, 학교에서의 행복감, 친구들에 대한 기대와 부모의 기대가 의미 있게 나타났다. 상위권 학생들의 경우는 학교수준에서는 교사의 기대와 학부모 참여정도가 학생수준에서는 수학적 효능감, 교과가치, 독서시간, 부모의 학력과 기대, 그리고 교사의 기대가 의미 있는 변인으로 나타났다. 중위권 학생의 경우는 학교수준에서는 교사의 연수정도와 학부모 참여정도가 학생수준에서는 수학적 효능감과 학교에서의 행복과 친구기대가 의미 있는 변인으로 산출되었다. 하위권 학생들의 경우는 학교수준에서는 교사의 연수정도와 교사의 기대정도가 학생수준에서는 독서시간과 과외여부만이 의미 있는 변인으로 산출되었다.   The purpose of this study is to explore whether the contextual variables derived from previous studies affect different ability groups to the same degree. This study is based on analysis of TIMSS(the Trends in International Mathematics and Science study) 2003 using HLM(Hierarchical linear model). Results show that teacher"s expectation, teacher"s professional development, same content, different ability in class, and parent"s involving school activity among school level variables and expectation of the future education, self-confidence in mathematics, attitude to mathematics, reading time, extra lessons, happiness in school, expectation of friends and parents among student level variables have affected their mathematics achievement For high-performing students, teacher"s expectation, parent"s involvement of school activity, self-confidence in subjects, attitude to subject, reading time, parent"s educational level and expectation have affected their mathematics achievement. For middle group students, teacher"s professional development, parent"s involvement of school activity, self-confidence in mathematics, expectation to friend, happiness in school have been affective factors. For low-performing students, teacher factors such as teacher"s professional development, and expectation, and student"s reading time and extra lesson have affected their achievements.

박충무(Chung-Mu Park),윤현서(Hyun-Seo Yoon) 인문사회과학기술융합학회 2018 예술인문사회융합멀티미디어논문지 Vol.8 No.9

본 연구는 2016년 12월부터 4개월간 일부지역 성인여성을 대상으로 스트레스지수와 구강자각증상과의 관련성을 알아보고 구강자각증상완화를 위한 방안을 모색하기 위한 기초자료로 삼고자 한다. 스트레스 수준은 20대, 대학졸업이상의 학력에서, 대학생에서 높았으나, 기혼, 음주를 하지 않는 경우, 농촌지역 거주 여성에서 스트레스 수준이 낮았다. 연령이 증가하고, 학력이 낮고, 자영업, 기혼에서 구강자각증상 인지 수준이 높았으며, 농촌지역, 흡연, 음주를 하지 않는 경우에 구강자극수준이 높았다. 스트레스가 높으면 입술에서는 입술이나 입술주위에 물집 형성(p=0.022), 볼 파임증상(p=0.043), 입술껍질 벗겨지고 피가 났으며(p=0.022), 혀에서는 혀의 통증(p=0.023), 미각장애(p=0.011), 혀의 갈라짐이 나타났다(p=0.005). 치아와 잇몸에서는 치아통증(p<0.001), 이 악물기와 이갈이(p=0.001)가 나타났고, 턱관절에서는 소리와 통증(p<0.001), 두통이 자주 나타났다(p<0.001). 따라서 스트레스로 인하여 구강 내 통증의 발생을 완화하기 위해서는 비타민섭취와 정기적 구강검진, 타액유출량 증가를 위한 입체조 등을 제안할 수 있다. The purpose of this study was to examine the relationship between the stress index and perceived oral symptoms of adult women in some regions for four months from December, 2016, and to provide information on how to relieve perceived oral symptoms. As for stress level, the women who were in their 20s, who had college or higher degrees and who were college students were under heavier stress, and the women who were married, who didn t drink and who resided in rural areas were less stressed. More perceived oral symptoms were found in the older, less-educated, self-employed and married women, and there were less perceived oral symptoms in the respondents who dwelled in rural regions, who didn t drink and who didn t smoke. When there was heavier stress, the lip symptoms that accompanied it were blisters on or around the lips(p=0.022), dipped cheeks(p=0.043) and peeled lips or lip bleeding(p=0.022), and the tongue symptoms were tongue pain(p=0.023), dysgeusis(p=0.011) and chapped tongue(p=0.005). The tooth and gingival symptoms were toothache(p<0.001) and clenching/gnashing(p=0.001). The temporomandibular joint symptoms were sounding and pain(p<0.001), and frequent headaches took place(p<0.001). Accordingly, vitamin intake, regular oral checkups and oral exercise that can facilitate salivating could be suggested as ways to minimize the occurrence of oral pains caused by stress.
