The effects of bulk processing conditions on the bulk properties of modacrylic fibers were studied. The results showed that the pre-wet sprayed filament was textured more uniformly than the unsprayed one. It also showed that the crimp rigidity increased with increasing gear temperature, but above an optimum temperature it decrease with increasing gear temperature, and the fibers showed apparent damage above the optimum temperature. The important parameters with affect the bulk property are the texturing temperature and its residence time. The optimum gear temperature of modacrylic fiber was about 8$0^{\circ}C$ to 9$0^{\circ}C$. An increase in the residence time increases the crimp rigidity very sharply, and then it tends to flatten out to constant value at longer residence time.

The purpose of this study was to understand the visual effect of green revegetation upon bared dam-side slope appeared between the water level alteration section. The 8 test photos were prepared by simulation according to several conditions of flooded days and vegetating method. The data were collected by presenting the prepared pictures, asking subjects to fill out questionnaires. Upon the original bared landscape, between spring-summer and fall, fall(S5) landscape was evaluated presenting stronger image toward minus effect than spring-summer(S1) landscape. Fall(S5)/spring-summer(S1) landscapes were evaluates as rough(3.75/3.13), damaged(3.60/2.93), ugly(3.50/3.28), simple(3.83/3.62), disharmonious were evaluated better image than original bared landscapes not discriminating season. For the general visual preference, totaly revegetated spring-summer landscape(S4) was highly evaluated(3.83) among tested landscapes compared with revegetated fall(S8. 3.11) or bared spring-summer(S1, 2.87). This means that the trend of visual preference for the dam-side slope rise following to green cover rate increase.

The effects of processing conditions on the bulk properties of PVC fibers were studied. The results showed that the pre-wet sprayed filament is textured better and move uniformly than unsprayed one. But it was confirmed that the fibers textured over Tg showed some damage by projectina and SEM photos, and by tensile test. The important parameters which affect the bulk property are the texturing temperature and its residence time. The optimum gear temperature of PVC fiber was in the neighborhood of 75$^{\circ}C$ to 85$^{\circ}C$. And residence time about 0.7 sec was at least required for the rearrangement of the molecular chain.

To evaluate the bike-environment of neighboring community in Cheongju, 'Copenhagenize Index' - which was developed for the purpose of evaluating bike-environment of world cities. For the study, 13 Index system was revised to 10 Index system appropriate for Chongju. Several Indexes judged be difficult or impossible to apply were changed or discarded considering the regional environments. Questionnaire items to each Indexes were developed and surveyed as a next step. Evaluated bike-environment of Cheongju was scored point 50 - which is very low score comparing to Amsterdam(83) or Copenhagen(81). Among 10 indexes, 'Bicycle Culture' and 'Social Acceptance' highly scored at 8.82 and 7.08 each. But "Perception of Safety' and 'Urban Planning' were low scored at 2.92 and 3.19. Therefore, Cheongju City government should consider bicycle safety education, bicycle plan to lower the risk of bicycle accidents, and a balance road system. This results indicate the future orientation of Cheongju's bicycle policy precisely.

Leisure & Recreation resources and demands were surveyed and analysed at regional scale through the book review and questionnaire method to propose leisure resource development and recreation management system of Chongju area in Korea. 7 point liquert scale was used for several questions to evaluate some leisure environments of the study area. Followings are the findings of the study and the proposals for the leisure policy of the study region, Chongju area. 1. Basic leisure conditions(personal or environmental) were self-evaluated as so low level. Special considerations are required to several environmental conditions like quantity, complexity and facility management for the better leisure life of the residents. 2. To over 65% of the existing leisure resources, residents'knowledege were evaluated below average level. On this situation, more systematic and effective information delivery system should be prepared. 3. Accessability, inexpensiveness, pleasantness were found to be the major factors for the leisure resource destination. At present situation, the residents mostly prefered the theme-park styles like zoo/botanic garden, play-equipment complex, folk village. But if consider the long term point of view, demands for more active and expensive activities seem to be increased. 4. About fifty percent of the present leisure activity was included in the location of 50-60km and 2hour distance radius area. And seventy to eighty percent, in the 100km and 2.5hour. Considering that results, regional leisure resources are recommended to be distributed and developed with the following context ; urban parks for teenagers and aged, suburbans for youth, and the remote nature areas for manhoods.

문석기 한국조경학회 1987 韓國造景學會誌 Vol.15 No.2

The concept of ‘Open Space’ is conceived to be very valuable subject of interest in developing modern settlement system. In Korea, many new and old residential sites have been developed or renewed to fulfil the housing demands. And such trends seem to continue for the time being. What is more, the requirments for more comfortable residential environments, that is deeply concerned with ‘Open Space’, inorease gradually. As a basis for designing more efficent residential environments to fit Korean morden life style, self - grown, traditional and agricultural villages are studied. This study is concenturated on the Open Space System with its socio - cultural and physical backgrounds. For this, data and materials are some widely collected and are analysed focused on the systems and structures of ‘Open Spaee’. Some results from this study are summarized as follow ; 1. It is assumed that the number of houses per village is around 60, and that its area reaches to the radious of 3-4km. 2. ‘POONGSU’is a generally adopted theory based on natural elements like mountians, waters, and orientations when locating villages and composing their spatial structures. As a result of this, the basic structures of villages and Open Space are defined. 3. Circulation system is integrated to the hierachyal order system ; that is, Passing Road \longrightarrowEntry Road\longrightarrowCentral Read\longrightarrowDisperse and Access Road. 4. The natural and agricultural land uses are overlapped with diverse outdoor activities - religious services, play and recreation, relaxation, etc - without any physical modification. 5. At each villages, several artificial and spot - like green facilities are found. And distinctive functions, meanings, and locationalities are given to each of them. On that, they become a visual and psychological centers of each village. 6. In addition to its basic function of circulation, Central Road takes the sence of place for outdoor activities. Because of this charactor, it plays an important role of activating the village life and binding the various Open Space elements.
