본 연구는 하절기 크리핑 벤트그래스의 품종별 생육특성을 파악하고자 수행하였다. 하절기에 품질이 가장 나빴던 품종은 Penncross 였으며 가장 좋았던 품종은 Pen A-4와 Crenshaw 였다. Putter의 경우 하절기에도 품질의 변화가 크지 않아 조사기간 내내 고른 품질을 유지한 품종으로 평가되었다. 하절기에도 엽록소 함량이 우수한 품종은 Crenshaw, L-93과 Pem A-4였으며, 가장 낮았던 품종은 Penncross이고 SR1020도 상당히 낮은 그룹에 속하였다. 시비 후 엽록소 함량이 가장 많이 증가하는 품종은 Putter였다. 최고온기인 8월 초에 $1cm^2$ 단위면적당 밀도가 가장 높은 품종은 L-93으로 19.3개이었고 그 다음은 Crenshaw, Pen A-4, Putter, Dominant, SR1020, Penncross 순으로 나타났다. 가장 낮았던 Penncross의 밀도는 15.7 개였다. 뿌리생육이 가장 좋았던 품종은 L-93으로 하절기에도 평균 5.5cm이상을 유지하는 것으로 나타났으며 Pen A-4와 Putter의 뿌리생육도 양호한 것으로 나타났다. 하지만 SR1020, Penncross, Dominant품종은 하절기에 뿌리생육이 급격히 감소하였다. 실험 기간 동안 가장 문제가 되었던 잔디병은 브라운 패취였으며 Penncross를 제외한 모든 품종에서 Brown patch가 발생되었다. Dominant가 가장 많았고 Putter, L-93, Crenshaw, SR1020, Penn A-4 순으로 나타났다. 하절기조류 피해가 가장 적은 품종은 Penn A-4였으며, Dominant가 가장 심한 것으로 나타났다. 본 실험을 통해, 하절기 생육이 가장 우수하였던 품종은 Crenshaw, Penn A-4, L-93 이었으며 가장 불량하였던 품종은 Penncross 였다. 하지만, 이는 조성 1년차 그린에서 나타난 결과이므로, 앞으로 시간이 경과함에 따라 나타나는 다양한 품종의 특성에 대한 종합적인 연구가 이루어져야 할 것으로 사료되었다. This study was initiated to evaluate the growth characteristics of seven creeping bentgrass cultivars in summer, 'Penncross' showed the worst visual quality, whereas 'Penn A-4' and 'Crenshaw' the best quality. 'Putter', which was maintained a fair quality during the test period, was regarded as a good cultivar because of no significant variation in summer as compared to the other caltivars. 'Crenshaw',' L-93' and 'Penn A-4' were greater in chlorophyll content and 'Penncross' lowest during the summer. Also, 'SR1020' had a low content of chlorophyll. 'Putter' greatly increased in chlorophyll content after fertilization. The highest shoot density($19.3/cm^2$) was found with 'L-93' in early August, followed by 'Crenshaw', 'Penn A-4', 'Putter', 'Dominant', and 'SR1020' in that order. However, 'Penncross' was lowest($15.7/cm^2$). As for a root length, 'L-93' was longest, being over an average 5.5cm. 'Penn A-4' and 'Putter' also showed good result in root growth. However, the root length considerably decreased with 'SR1020', 'Penncross' and 'Dominant' in summer. Brown patch was a serious disease for the most cultivars, except 'Penncross'. 'Dominant' had the most serious damage. 'Putter', 'L-93', 'Crenshaw', 'SR1020', and 'Penn A-4' were also greater in damage over the others. In regards of algae occurrence in summer, 'Penn A-4' had the least damage, while 'Dominant' the greatest. In conclusion, 'Crenshaw', 'Penn A-4' and 'L-93' were the best cultivars in terms of summer growth. Conversely, 'Penncross' was the poorest one. However, this study was conducted under the conditions of one-year old green. Accordingly, in-depth experiment should be done over several years to elucidate the characteristics of growth for the wide range of creeping bentgrass cultivars during the summer.

The children's playgrounds are the places where children can improve their health and keep it in good shape. Play in the childhood can stimulate their emotions, help them improve their emotional ability and accelerate their intellectual desires, sociability. In the respect, the playgrounds are very important in conjunction to the children's physical and mental growth. But these places are not widely utilized because they cannot meet the children's curiosity and interests. Therefore the purpose oh this study provides basic data based on the survey of the kinds of the facilities and color to solve the problem of the present facilities, to build new facilities, which can satisfy children's interests. We also checked out the surface temperatures of the materials used to make facilities and the risk of it's users to find appropriate materials. According to the results, we found out that there were 19 types of different facilities in total 24 playgrounds. The most often found facilities are seesaw, swing, slides, mixed play lot, merry-go-round, iron bar and jungle gym. The above mentioned seven things consist of 71.49 percent of facilities. Children get bored so easily that we need to diversify the kinds of facilities to meet children's desire to experience various things. The survey revealed that there were approximately 60 kinds of colors on play facilities in playground. Among them, red took up 30.4 percent of total colors, green 27.1percent, yellow 23.5percent, these three colors took up more than 80percent and used in the most of facilities. Although most of play facilities were red, children disliked red color. Base on this result, we could suggest that using red colors to play facilities was inappropriate. We also found that children liked blue the most, but blue was rarely used in play facilities. The highest surface temperature of facilities surveyed is rubber, carbon iron plate, stainless steel, woods, iron bar and concrete. The rubber and the used tires are mainly used for making the saddles of swings. The surface temperature of the saddles which directly contact to the children's skin is highest. Children can easily feel hot when they slip on the slide made of carbon iron plate. On this respect, we need to introduce new materials for facilities.

집합주거 단지내의 어린이놀이터 활성화 방안에 관한 연구 : 놀이시설물의 색채 및 선호도를 중심으로 Special Consideration of the Color and Preference of the Playground Facilities

Presently, playground is not able to attract the children's interest. Therefore playground becomes less popular place for children. Since it was suggest that children responded more sensitive to the color compared to the form, we investigated the color of playground facilities and the children's color preference for playground facilities. The results are following; 1. According to the previously published data, children like yellow the most, then yellow green, blue, and green the least. However, the survey showed that children liked the blue for play facilities the most, bluish green, yellow, and dark blue was the least. These results indicated that the color of play facilities, which children prefer, was differ from the color which they prefer. 2. The survey revealed that there were approximately 60 kinds of colors on play facilities in playground. Among them, red took up 30.4% of total colors, green 27.1%, yellow 23.5%, these three colors took up more than 80% and used in the most of play facilities. 3. In terms of color preference, there was no significant statistical difference between sex. However, We could find significant difference about color preference between lower grade students and upper grade ones. It showed that lower grades children liked yellow, bluish green, yellowish green, purple. However, upper grade children liked scarlet, green, blue, dark blue, purplish red.
