The purpose of this study is to investigate the prime factors that affect to user postoccupancy evaluation of activities and facilities in urban parks, to classify those factors, to find out factors about them, and then to suggest important indicators in the urban park planning, design, and development. The survey research was done using the self-administered questionnaire method by 435 peoples in the Busan City who participated in recreational activities in the Amnam Park. The Analysis of the data primarily consists of two phase: The first analysis was dealt an exploratory factor analysis which identified major factors involved in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the SPSS(Ver.6.0) program and the second analysis was used to investigate the factors affected to user postoccupancy evaluation in the urban park by the Regression Analysis. According to the factor analysis, user postoccupancy evaluation of facilities in urban parks concerning the 20 variables, 5 prime factors by the staistical values were considered. The factor analysis showed that user postoccupancy evaluation of activities in urban parks concerning the 11 variables, 3 prime factors by the staistical values were analysed. Postoccupancy evaluation in the urban park by the Regression Analysis suggested that the two varlables as 'the directions of park development' and 'companies with the personal specific characteristics' are significant in addition to the some variables presented in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the factor analysis. Furthomore the analysis models were identified as having significant effects on the factor and regression analysis. Overall fits of both models were very good. These significant relationships indicate important factors and variables that should be considered in planning, design, and development of the urban parks. Therefore, development direction of the h a m park has to be analyzed as significant factors concerning user postoccupancy evaluation in a systematic way, recognized as important variables for planning process. The urban park has to be fully designed and established in the planning process not by the decision-maker's subjective evaluation but by user postoccupancy evaluation.
The data for this research were collected by the standarized interview in the mountaneous National Park of Mt. Songni on October of 1982. F-test was applied to analyse the significant differences among the activities in the park by the type of accommodations and by the purpose of visits. Demand functions for the whole tourism and recreation experience of the national parks were taken by the OLS regression after multiplying the square roots of the populations to various variables. Demand functions for the national park were also taken by the regression. Finally the tourism and recreation values of the parks per user-day and for 1984 year were estimated by the main activities in the parks. The main results are summarized as follows: 1. In Mt. Songni, demands for the national park also differed at 1% significance level by the type of accommodations: inn, private house, camp, and by the purpose of visits: relaxation, mount climbing and camping. 2. In Mt. Songni, the demand function for the whole experience was well fitted by the variables of the round distances and the amount of local taxes per person; R²=0.661. The demand functions for the whole experience by the type of accommodations: inn, private house, no overnight and by the purpose of visits: relaxation and mount-climbing were well explained by the variables of the round distances and the populations, but the demand for the whole experience of the users of camp and for camping was well fitted by the variables of the round distances and the amount of local taxes per person. 3. In Mt. Songni, the demand function for the national park was well fitted by the added costs (in km); R²=0.946. The demand for the park was theoretically 1 person when the added cost was 1,097Km. The demand functions for the park by the type of accommodations were also well fitted by the added cost (in km). When the added cost was 1,840km, Which was the largest, the demand for the activity to use the private house was theoretically 1 person. Those demand functions for the park by the purpose of visits were well explained by the added cost (in km). When the added cost was 1,503km, which was the largest, the theoretical demand for the mount-climbing was 1 person. 4. In Mt. Songni, the tourism and recreation value of the national park by the total users was 209.09km per user-day and 225.51 million km for 1984 year. The tourism and recreation values of the park by the users and by the type of accommodations: inn, camp, private house, no over-night were respectively 371.14km, 116.16km, 420.38km, and 124.75km per user-day. The tourism and recreation value of the park for 1984 year was 100.22 million km in case of the users who used inn and 81.44 million km in case of the users who didn't stay overnight. By the purpose of visits, the users who visited the park for mount-climbing valued for the park the largest 225.03km and those for relaxation valued 222.71km per user-day. The largest value by the users for 1984 year among the purpose of visits was 99.15 million km in case of the users who visited the park for mount-climbing and the next largest value was 85.24 million km in case of the users for relaxation.
In America and Europe from the latter part of the 19th century to the beginning of the 20th century, the planning ideologies of park system and greenbelts were made and these planning ideologies are called Green Network System. They are different in terms of the purpose, type and method, but they have common characteristics of encouraging order and amenity in cities based on the consecutive connection of green space, and of coping with the problems happening in cities. Just as the park system was made, centering around new America and greenbelts were developed to meet with the problems happening in large cities, the structural arrangement and the roles of greens should be different. However, this connection system of greens was oriented in the circumstances of America and Europe at that time so it has not been confirmed what sizes of cities it would be useful for. On the other hand, separately from the Green Network System, the theory of park arrangement is being developed. It intends to cope with deterioration of the living environment caused by overcrowded cities and with increase in the demands of public parks. It is based on the neighborhood unit and the science of human settlement. In addition, the theory of park arrangement is based on the effects of greens in use, rather than, in decoration so it encourages dispersion and hierarchical system of parks, having the human settlement as base. Consequently, the theory of park arrangement is influenced by the characteristics and the type of households, and it has a required area and planning unit. However, this theory has the right for walking and human scale as the basic unit so for the large parks that are beyond the human scale, the planning criteria are not clear. The theory of park arrangement, which is based on the neighborhood unit, may be useful for the cities with tens of thousands of residents, but it is partially applied for the cities with 500,000~1,000,000 residents. And further, in organizing the green system for the whole city, the theory of park arrangement can be ignored. As seen in the above, the existing arrangement theory has some problems: it is just for partial application; and it is not suitable for the size and the growing speed of cities. The greens in cities should be operated as the comprehensive system, but greenbelts and park arrangement have been studied separately so far. That`s why it is necessary to review again the existing arrangement theory.
The Mountainous National Park is the area where it has the coexisted purposes, use and preservation, which cannot be harmonized. But in recent year, it is natural tendency that the use of the National Park is increasing day by day and the fact is that the side of use than preservation is emphasized. Especially in leisure society as today, even the appointment itself of the National Park is the factor that use can be increased and because it has the great influence affecting to the neighboring community economy including the National Park its neighbors have a marked leaning toward the use of two purposes and insist only development. In fact, the area of most National Park is equipped with the necessary facility to offer convenience of the user. But such necessity causes the increase of the weighted level of use in liaison with the requests of development of its inhabitants. But the National Park, for the original purposes, must keep the balance between use and preservation. Because the natural environmental condition that the National Park has is the product of nature and cannot be produced by human-power the demand cannot be met by the increase of supply even though the requests for the offer of natural environment are increased. Therefore, to keep the balance between use and preservation it is necessary that there should be consideration for the usable side and preservable one of resource, the National Park. This can be said by the concept of social carrying capacity and ecological carrying capacity. Accordingly the concept of carrying capacity of the National Park is formed by the duplicated projections of the ecological carrying capacity and the social one. In addition these carrying capacity of the Mountainous National Parks are used for the efficient management objectives of them and they offer the policy frame necessary for their future purpose. Finally, the results from this research work are as follows: 1. We can define the concept of the carrying capacity of the Mountainous National Park consisting of the total of management objectives, ecological carrying capacity and social carrying capacity as the level which the characteristics of the Mountainous National Park can be maintained without the deterioration in quality of experience of user and ecological environment. 2. The major key points consisting of the concepts of the carrying capacity of the Mountainous National Park necessarily require the establishment of the concrete and clear management objective. 3. The management of the Mountainous National Park, centering around the zoning district, requires the establishment of the levels of management and the followings are required by each level. 1) non-interference. 2) the intensive management. 3) the more intensive management. 4. We must recognize the management objectives of the Mountainous National Park as the limitation of acceptable changes. 5. The concept of the carrying capacity of the Mountainous National Park can use for the policy level deciding the means and strategies for the management of the Mountainous National Park.
주차안내 시스템은 주차장에서 주차정보를 제공하여 운전자에게 주차 편리성을 제공한다. 동시에 다수의 센서, 디스플레이와 제어모듈을 이용하여 아주 소량의 전기 에너지 만을 소모한다. 녹색 빌딩 설계의 요구가 점차 증가함에 따라 주차관리 시스템의 운용 전력 감축 문제가 이수화 되고 있다. 본 논문에서는 주차 관리 시스템의 감지기와 디스플레이 장치의 설계와 소비전력 감축의 결과를 제시한다. 이 시스템은 무선 Park Tile 과 Park Disk를 사용하여 전력소비를 감축 시키고, 여러 개의 주차공간 감지기와 자동차 카운터, 정보 디스플레이 장치, 안내 터미널과 제어장치로 구성되어 있다. 그리고 시스템 구조설계와 통신망 설계, 주차정보 서비스 시나리오 설계, .배터리 수명 제어, 운영 전력 평가 등이 수행되었다. 주차장당 운영전력은 0.4W로 평가 되었으며, 이는 기존 시스템의 17%정도 이고 매년 유지비는 기존 시스템에 비해 43%에 해당된다. The parking guidance system can increase driver’s convenience with detailed parking information service in the parking lot. At the same time, parking guidance system consumes non-negligible electrical energy with large amount of sensors, displays and control modules. With the increase in the demand for green and sustainable building design all over the world, it becomes a meaningful issue for parking guidance system to reduce operating power. This paper presents the preliminary design and estimated results of a parking guidance system which is optimized to reduce the power consumption mainly on detectors and displays. The system design is based on pre-developed wireless parking detectors, Park Tile and Park Disk. The system has a number of parking space detectors, vehicle count detectors, information displays, guidance terminals and other control units. We have performed system architecture design, communication network design, parking information service scenario planning, battery life regulation and at last operating power estimation. The estimated operating power was 0.4 watt per parking-slot, which is 17% of traditional systems. The estimated annual maintain cost was 43% of traditional systems.
In this paper, we described about evaluation of human sensibility using park assist system of the commercial vehicle. The perpendicular parking and parallel parking have been carried out as a user test and subjects are classified as beginning drivers, drivers with less than 1 year experience and over 3 years experience. As a result, parking duration of beginning drivers and drivers with less than 1 year experience who use automatic parking assistance system is similar to drivers with over 3 years experience. However error occurred according to sensor position and distance between vehicle and parking space. And also it occurred that the vehicle leaves from parking line or does not recognize the parking space. Therefore, if we improve its completeness by compensating problems that came up from this evaluation and distribute the automatic parking assistance system, it is expected that the park assistance system is to help driver providing convenience of parking.
The purpose of this investigation is to propose a planning method for the possibility of accepting a housing as a utilization plan of a long term unexecuted park site. Currently, the park has been neglected due to lack of financial resources of the local government. In 2009, It is possible to develop a certain area as a non-park facility under condition that the park is built and donated. In the several cities, various projects for development of parks are being carried out, so the standard for securing the publicness of the park is needed. So, I would like to solve the problems such as social conflict with existing residents due to privatization of the park site and formation of park without considering the conditions of the park, and to study how to effectively utilize the park. To do this, we examine the conditions such as location condition, proximity to public transportation, site size, topography, and contact conditions. And we will present realization methods such as land use, development density, appropriate development method considering landscape, efficient housing type, and type of community facility.
본 연구는 박두진의 유년시절의 의식이 박두진의 성장기는 물론이고 청년기와 장년기, 나아가 노년기에 이르기까지 영향을 미친다는 관점을 보이고 있다. 박두진의 특수한 경험에 해당되는 유년기의 가난은 박두진을 좌절시키기보다는 오히려 박두진의 일생에 걸쳐 박두진을 곧고 강한 인물이 되도록 할 수 있었던 요인이 되었던 것이다. 물론 유년기의 불우했던 환경이 모든 이에게 긍정적인 방향으로 귀결되지는 않았을 것이나 박두진은 이러한 조건에 굴복한 것이 아니라 이를 딛고 자신의 인생을 개척했음을 알 수 있다. 이는 박두진의 강직하고도 자의식 강한 성품을 말해주는바, 본고를 통해 박두진의 유년기의 정신적 풍경을 살펴봄으로써 그의 어떠한 요인이 그의 삶을 바르고 곧은 길로 이끌었는지 확인하고자 하였다. 지독한 가난으로 잦은 이사를 다니면서 동네 아이들로부터 심한 따돌림으로 고통 받아야 했던 박두진에게 산과의 인연은 절대적인 요인으로 다가왔다. 가난의 고통과 텃세로 인해 죽음을 생각할 만큼 열등감에 시달렸던 박두진에게 산은 놀이 공간이자 안식처였고 구원의 지대였다. 또한 산은 박두진에게 하나의 공동체였고 삶의 터전이었다. 박두진은 온갖 생명이 생기가 넘쳐나는 산을 통해 자유와 평등과 사랑으로 공동체를 이루고 살아가는 모습을 보게 되었고 생의 의욕을 다지게 된다. 산을 오르내리면서 얻게 되었던 이러한 체험은 소년 박두진을 좌절로부터 일으켜 세움으로써 그의 이상과 의지와 꿈을 형성하게 한 계기가 되었다. 이는 박두진이 에릭슨이 말한 바 유아 남성성의 단계를 슬기롭게 겪음으로써 ‘유능함’의 삶의 과정을 거치게 되었음을 말해준다. 유년기 산에서의 체험에 힘입어 박두진은 인생의 매 시기 강건하고 올곧은 선택을 할 수 있었고 이는 박두진의 시력의 세 단계로 나타나게 되었다. 그것은 첫째 산에서의 행복했던 체험에 바탕을 둔 초기 자연시와 관련되며 둘째 산에서 발견한 공동체의 모습에 의지하여 중기에 보여주었던 사회참여시와 관련되고, 셋째 산에서 얻게 된 이상적 공간에 대한 감각에 따른 후기의 신앙시와 관련된다. 산에서 외로움과 고통으로부터 벗어날 수 있었던 박두진에게 산은 안식의 공간이었을 뿐만 아니라 이상적인 공동체였으며 바른 삶을 살 수 있도록 하는 안내자였던 것이다. 이는 산에서 겪었던 유년기의 체험이 그의 시력에 결정적인 영향력으로 작용했음을 말해준다. 즉 소년 박두진은 산을 오르내리면서 많은 생각을 하게 되었고 이때 다져진 그의 굳은 의지는 박두진의 가슴에 화석처럼 쌓여 일생 동안 길잡이가 되었던 것이다. 박두진의 초기, 중기, 후기의 시들이 모두 변함없이 일관되게 강직하고도 완전한 형태로 이루어질 수 있었던 것도 이러한 사정에 기인한다. This study shows that Park’s childhood consciousness influences Park’s growing years, youth, and even the first years of life. The childhood poverty, which is equivalent to Park Doo-Jin’s special experience, could have made Park Doo-Jin a straight and strong character over her lifetime rather than let Park Doo-Jin be frustrated. Of course, the poor childhood environment may not have resulted in a positive one for everyone, but Park Doo-Jin overcame these conditions to learn about it. It shows Park’s strong and self-conscious character, and reveals what factors led Park in his life to the mental landscape. For Park Doo-Jin, who had to suffer from severe bullying by local children after moving around a lot due to extreme poverty, the bond with the mountain has become an essential factor. For Park Doo-Jin, who suffered from poverty and inferiority complex that made him think about his death, the mountain was a playground, a haven, and a land of salvation. The mountain was also a community for Park Doo-Jin and a place to live. Park Doo-Jin saw all kinds of lives forming a community of freedom, equality and love through the lively mountain, and he became more passionate about his life. The experience, which was gained from climbing the mountain, helped raise the boy Park Doo-Jin from frustration, forming his ideals, will, and dreams. It tells us that Park Doo-Jin has gone through what Erickson calls the “capable” lifestyle process by going through the smart phase of infant manhood. Thanks to his experiences in the mountain, he was able to make strong, straight choices during each phase of his life, which appeared to be three stages of Park’s vision. First, it is related to the early natural poetry based on the mountain experience, second, it is associated with the social participation in the latter phase of the year, depending on the appearance of the community found. Third, it is related with the latter faithful poetry. For Park Doo-Jin, who was able to escape from loneliness and suffering in the mountain, it was not only a place of rest, but also an ideal community and a guide to a just life. It suggests that his childhood experiences in the mountain served as a decisive factor in his vision. The boy, Park Doo-Jin, came up with many thoughts as he traveled around the mountain, and his strong will was wrapped up in Park’s chest like a fossil, making him a guide throughout his life. It is also due to these circumstances that Park Doo-Jin’s early, mid-and-after and later-the-day poems could all be performed consistently and in a complete form.

Since the early Chosun, the Milyang Park’s(밀양박씨) had lived in Cheongdo. It is not discovered yet how Park Gun(朴乾), who had moved first to Cheongdo, had lived. Therefore, I want to explain how Milyang Park’s settled down there and adjusted to it. Park Ik(朴翊), Park Gun’s grandfather, was raised in the native Milyang Park’s family, and held the post of Yea-Jo-Pan-Seo(예조판서). However he retired to this hometown against the foundation of Chosun Dynasty. His four sons were not in the government services, but they held government offices thanks to the will of Park Ik, who died in 1398. The first son, Park Yung(朴融), passed the classical examination and held the post of the governor of KyoungsangDosa(慶尙都事), and this made him closely connected with Cheongdo. As a result, he had his son, Park Gun, marry the daughter of Kim Cheol-sung(金哲誠). This led Park Gun move to Cheongdo where his wife’s family lived. After that, Park Seung-won(朴承元), the son of Park Gun, became Ha Suk-pu’s son in law. At that time, Ha Suk-pu(河叔溥) was the richest person in Cheongdo. However he didn’t have any sons to leave his great estate and slaves to, so Park Seung-won inherited all those estate and slaves. This made the Park’s become stable economically. Both Park Gun’s father and grandfather passed the classical examinations, and both he and his only son, Park Seung-won, passed the military service examinations. Being in the central government services helped them to make the field of their business wider in their hometown. Furthermore, it was a strong backing for the descendants to become Sa-lim(士林), the representatives of that area. At that time, the same families lived together in one village. This story shows how the Milyang Park’s village became the biggest ever.
