김경남,권오달,심상렬,윤중서,박소향,Kim, Kyoung-Nam,Kwon, O-Dal,Shim, Sang-Ryul,Yoon, Jung-Seo,Park, So-Hyang 한국잔디학회 2011 한국잔디학회지 Vol.25 No.1

본 실험은 자연 실온 환경에서 크리핑 벤트그래스 신품종의 초기 발아특성 및 발아패턴을 조사하고, 그리고 변온 및 자연실은 환경에서의 그 차이점을 비교 분석해서 실무 시공에 응용할 수 있는 기초자료를 파악하고자 시작하였다. 공시재료는 크리핑 벤트그래스 7품종이었으며, 일일 발아패턴 및 누적 발아패턴을 1일 간격으로 조사하였다. 크리핑 벤트그래스 종자의 발아율, 발아패턴 및 발아특성은 온도 조건 및 품종에 따라 차이가 크게 나타났다. 공시 품종 모두 최초 발아는 ISTA 변온환경 에서 치상 후 4-5 일 사이에 시작되었지만, 자연 실온 환경에서는 대부분 품종이 ISTA 변온보다 2~3일 늦은 6~8일 사이에 시작되었다. 최초 발아 시 발아율은 ISTA 변온에서 일반적으로 5~25% 정도였고, 'Penn A-1', 'Penncross' 및 'Penn A-4' 품종의 최초 발아율은 50~70% 정도로 초기 발아가 대단히 왕성하였다. 하지만 자연 실온 환경에서 최초 발아율은 일반적으로 5~10% 정도였으며, 'Penncross', 'L-93' 및 'Penn A-4' 품종은 20~50% 정도로 초기 발아 특성이 대단히 왕성하였다. 크리핑 벤트그래스에서 발아율 50% 도달 기간은 ISTA 변온에서는 치상 후 4~10일 사이에 나타났고, 자연 실온에서는 품종에 따라 ISTA 변온보다 2~5일 정도 늦은 치상 후 6~15일 사이에 나타났다. 발아율 85% 도달 기간은 ISTA 변온에서는 치상 후 5.90~11.75일 사이였으며, 가장 빠른 종류는 'Penn A-1' 품종이었다. 하지만 자연 실온에서는 ISTA 변온보다 다소 늦은 치상 후 7.95~12.50일 사이였고, 가장 빠른 종류는 'L-93' 품종이었다. 그리고 온도 조건에 관계없이 기준 발아율 도달 기간이 가장 느린 품종은 ISTA 변온 및 자연 실온에서 각각 11.75일 및 12.50일로 나타난 'T-1' 품종이었다. 본 실험 결과 나타난 이러한 발아특성 비교 데이터는 골프장 등 잔디밭 조성 시 실무적인 기초 자료로 유용하게 활용될 수 있을 것이다. This study was conducted to investigate early germination characteristics and germination pattern of new cultivars of creeping bentgrass (CB, Agrostis pall/stris Huds.) under natural room temperature conditions and to analyze differences between alternative and natural conditions. Seven cultivars of CB were tested in the study. Daily and cumulative germination patterns were measured and analyzed on a daily basis. Significant differences were observed in germination pattern, days to the first germination, days to 50% germination, days to 85% germination, and germination rate among cultivars under different environments. The first germination in all entries was initiated between 4 and 5 days after seeding (DAS) under alternative conditions, while between 6 and 8 DAS under natural conditions, being 2 to 3 days later as compared with that of alternative conditions. As for the first germination percentage, it was generally 5 to 25% under alternative conditions. However, 'Penn A-1', 'Penncross', and 'Penn A-4' cultivars showed a vigorous germination, producing 50 to 70%. Under natural room temperature conditions, it was 5 to 10% for the most entries, except 'Penncross', 'L-93', and 'Penn A-4' cultivars which vigorously produced 20 to 50%. Days to the 50% germination in CB resulted in 4 to 10 DAS under alternative conditions, while 6 to 15 DAS under natural conditions, being 2 to 5 days later than under alternative conditions. Days to the 85% germination were 5.90 to 11.75 DAS under alternative conditions and 7.95 to 12.50 DAS under natural conditions. 'Penn A-1' and 'L-93' were the fastest cultivars under alternative and natural conditions, respectively. Regardless of the temperature conditions, the longest cultivar in germination was 'T-1', being over 11 DAS. In-depth comparative data on germination characteristics and germination patterns among CB cultivars would be usefully applied for a practical CB turf establishment in golf course construction etc.

지역방재력 평가에 관한 연구(2): 강원도를 중심으로

김경남,권건주,백민호,Kim,Kyoung-Nam,Kwon,Gun-Ju,Baek,Min-Ho 한국방재학회 2009 한국방재학회논문집 Vol.9 No.1

지금까지 우리나라의 재난관리 활동은 재난관리의 주체가 전적으로 국가 및 지방자치단체인 공공행정이 책임이라는 인식하에서 추진되었지만, 대형화되는 재난현장에서 공공분야만의 재난관리 역량으로는 실제 재난발생시 기대했던 효과를 내지 못하고 있는 것이 현실이다. 따라서, 본 연구는 이를 분석하기 위해, 사전에 주민대표(이, 통장)를 대상으로 대비-대응-복구 단계별 `주민개인-주민공동-민관협동` 에 의한 재난관리 대비태세를 중심으로 인터뷰를 실시하였으며, 이를 바탕으로 지역자율방재단원들이 지역방재력량을 발휘하기 위한 요소를 `위험 인지능력, 피난유도능력, 자주피난 대비능력, 방재체제 정비정도, 감시경계능력, 정보전달능력` 등 6가지로 분류하여 설문조사를 실시하고 분석하였다. Until now, Korea carried out disaster management under the perception that the central government or the local government bodies are totally responsible. However as the size of disasters become larger, the capacity of the public disaster management did not live up to the expectations. To analyze this issue, this research conducted interviews on disaster response readiness by `individual resident-residents cooperation-public/private collaboration` according to each preparedness-response-recovery stage, as resident representatives (Head of Ri, Head of Tong) as subjects. Based on the interviews, surveys were conducted to deduct the necessary factors needed for the general residents to exhibit disaster prevention capabilities. The surveys consist of 6 factors-risk perception, evacuation inductively, individual evacuation response, disaster prevention system, lookout & precaution, information communication.

USGA 지반구조에서 한지형 잔디의 여름 고온기 적응력, 색상 및 연중 녹색 유지기간 비교

김경남,Kim Kyoung-Nam 한국조경학회 2005 韓國造景學會誌 Vol.33 No.5

Research was initiated to investigate turf performance under USGA soil system. USGA system 45 centimeters deep was built with rootzone layer, intermediate layer, and drainage layer. Six turfgrass entries were comprised of 3 blends and 3 mixtures from cool-season grasses (CSG). Turfgrass color and quality ratings were best in spring and fall, especially early May to early July and late August to early November. Kentucky bluegrass (KB) consistently produced the greatest performance, while perennial ryegrass (PR) the poorest. Intermediate turf performance between KB and PR was observed with tall fescue (TF). Among CSG mixtures it increased with KB but decreased with PR. There were considerable variations in summer turf Performance. No summer drought injury was found in KB and TF. However, PR showed poor performance through summer as compared with others. Among mixtures, it decreased with PR. It was suggested that PR mix in less than $20\%$ in the mixtures to have an acceptable quality in summer. Cultural intensity also affected it. With lowering mowing height, KB of rhizomatous-type in growth habit kept good quality, while PR and TF with bunch-type in growth habit poor quality. Mowing quality was greatly different among CSG. KB produced clean-cut surface, but PR unclean one. If had an intermediate mowing quality between KB and PR. A great difference in green color retention was observed among CSG. The longest CSG was PR that kept green for 339 days, while the shortest one TF for 267 days. KB continued to keep green for 290 days. The mixtures kept green in color for 292 to 315 days, depending on turfgrass mixing intensity. The greater the PR in content, the longer the green color duration. These results demonstrate that KB was the best and PR the worst among CSG grown in USGA system under a domestic climate, in regards of turf quality, color, mowing quality, summer turf performance and green color duration. KB and TF are most adequate for high-maintenance and low-maintenance area, respectively. In case of mixtures for high-quality turf, it was desirable to use KB-based mixture with PR of below $20\%$ in seeding rate.

김경남,Kim, Kyoung-Nam 한국잔디학회 2009 한국잔디학회지 Vol.23 No.1

톨 훼스큐 종자의 발아율, 발아패턴 및 발아특성은 생육환경과 품종에 따라 차이가 크게 나타났다. 자연 실온 환경에서 발아력은 ISTA 변온과 약간 다르게 나타났고 최종 발아율은 $85.25{\sim}97.00%$ 사이로 다양하였다. 톨 훼스큐의 발아패턴은 최초 발아의 경우 ISTA 변온에 비해 $2{\sim}3$일 정도 늦은 치상 후 $7{\sim}9$일 사이에 시작되었다. 최초 발아 시기는 공시 품종 간 1일 정도 차이가 있었으며, Arid III 및 Olympic Gold 품종이 $7{\sim}8$일 사이로 다소 빨랐다. 발아율 50%에 도달한 기간은 최초 발아 후 $3{\sim}4$일 경과 후인 치상 후 $11{\sim}12$일 사이로 나타났으며, 이것은 ISTA 변온에 비해 $3{\sim}4$일 정도 늦은 것이었다. 또한 실무적으로 요구되는 발아율 76% 도달기간은 ISTA 변온에 비해 품종에 따라 $1.55{\sim}4.77$일 정도 늦은 치상 후 $12.38{\sim}14.29$일 사이로 나타났다. 공시 품종 중 75% 발아율 도달 기간이 가장 빠른 품종은 Olympic Gold 품종이었고, 반대로 가장 느린 종류는 Tar Heel II 품종이었다. 톨 훼스큐 품종 간 발아특성 및 발아패턴의 결과를 종합적으로 고려할 때 Olympic Gold 품종이 가장 우수한 것으로 사료되었다. 본 실험을 통해 밝혀진 품종 간 생리 생태적 특성과 ISTA 변은 및 자연 실온 조건 간 비교 자료는 골프장 등 잔디밭 조성 시 실무적인 기초 자료로 유용하게 활용될 수 있을 것이다. Research was initiated to investigate early establishment characteristics and germination pattern of tall fescue(TF, Festuca arundinacea Shreb.). Four varieties of TF were evaluated in the study. Experiment was conducted under a room temperature condition of $5^{\circ}C$ to $25^{\circ}C$(natural conditions). Daily and cumulative germination patterns were measured and analyzed on a daily basis. Significant differences were observed in germination patterns, days to the first germination, days to 50% germination, days to 75% germination, and germination percentage with different environments and varieties. Germination percentage was variable with varieties at the end of study. It was 85.25 to 97.00% under natural conditions. There were considerable variations in early germination characteristics and patterns among the entries according to different conditions. The first germination was initiated between 7 and 9 DAS(days after seeding) under natural conditions, being 2 to 3 days later as compared with ISTA conditions. It was 11 to 12 DAS in days to the 50% germination, which was 3 to 4 days after the first germination. Days to the 75% germination were 12.38 to 14.29 DAS, being 1.55 to 4.77 days slower as compared with ISTA conditions. Olympic Gold was regarded as the fastest variety and Tar Heel II was slowest. Data from this study demonstrated that information on differences in germination characteristics and patterns among varieties would be usefully applied for TF establishment such as golf course construction.

초흡수성 고분자 중합체가 크리핑 벤트그래스, 켄터키 블루그래스 및 들잔디의 잔디품질에 미치는 효과

김경남,Kim, Kyoung-Nam 한국잔디학회 2011 한국잔디학회지 Vol.25 No.1

본 연구는 토양개량재 혼합구에서 고분자 중합체 비율이 주요 초종의 잔디품질에 미치는 영향을 조사함으로 수분 흡수 중합체를 이용한 토양개량재의 개발 및 실무 응용에 활용할 수 있는 기초자료를 얻기 위해 수행하였다. 토양개량제 혼합구는 모래, 토양개량재 SOA 및 중합제 WSP를 이용하여 전체 12개 처리구틀 준비하였다. 온실에서 생장한 크리핑 벤트그래스, 켄터키 블루그래스 및 들잔디의 잔디품질은 토양개량재 SOA 및 WSP 중합체 혼합비율에 따라 유의한 차이가 나타났다. 초종별 잔디품질은 크리핑 벤트그래스 > 들잔디 > 켄터키 블루그래스 순서로 나타났고, 시각적 잔디품질 점수는 WSP 중합체 혼합비율에 따라 크리핑 벤트그래스 0.3~9.6, 켄터키 블루그래스 0.3~4.0 및 들잔디 0.9~5.8 사이로 초종 간 최대 5.6정도 차이가 있었다. 3종류 공시초종에서 잔디품질의 변화패턴은 WSP 중합체 혼합비율에 따라 경시적으로 다르게 나타났으며, 잔디품질을 고려할 때 혼합비율은 크리핑 벤트그래스와 들잔디는 5%, 켄터키 블루그래스는 5~10% 범위가 적절하였다. 잔디품질에 대한 전반적인 WSP 중합체 처리효과는 크리핑 벤트그래스, 켄터키 블루그래스 및 들잔디 모두 SOA 20% 혼합구에서 가장 양호하게 나타났다. 그리고 토양개량재 SOA를 함유한 식재층 토양에 WSP 중합체 혼합 시 SOA 혼합비율은 한지형인 크리핑 벤트그래스와 켄터키 블루그래스의 경우 15~20% 사이, 그리고 난지형인 들잔디는 20% 정도를 혼합하는 것이 적절하다고 판단되었다. 향후 유가질 토양개량재를 함유한 식재층 토양에서 0~15% 사이의 저수준의 WSP 중합체 혼합과 함께 칼슘, 펄라이트 등 무기 영양분이 초장, 밀도 및 품질 등 잔디생육 특성에 대한 효과검정을 통해 WSP 중합체를 이용한 토양개량재의 개발 및 실무 응용에 활용하는 것이 바람직하다. Research was initiated to investigate the effect of high water-absorbing polymer on turf grass quality of three major turfgrasses. A total of 12 treatment combinations were used in the study. Treatments were made with different rates of sand, soil organic amendment (SOA), and water-swelling polymer (WSP). Visual turf grass quality was evaluated in creeping bentgrass (Agrostis palustris Huds., CB), Kentucky bluegrass (Poa pratensis L., KB), and zoysiagrass (Zoysia japonica Steud., Zoy) grown under greenhouse conditions. Significant differences were observed among the treatments in CB, KB, and Zoy. Visual quality ratings varied with mixing rates of SOA and WSP, being maximum 5.6 in differences among them. At the end of study it ranged from 0.3 to 9.6 in CB, 0.3 to 4.0 in KB, and 0.9 to 5.8 in Zoy. Turfgrass quality pattern changed with time after seeding among treatments influenced by WSP rates. From this study, a proper rate of WSP is considered to be 5%, 5~10%, and 5% for CB, KB and Zoy, respectively. In general, overall treatment effect of WSP on turfgrass quality was highly associated with SOA 20% in three turtgrass species. When mixing sand with SOA and WSP for rootzone soil, a proper rate of SOA is considered to be 15 to 20% for CB and KB, while 20% for Zoy of warm-season grass. A further study would be required to investigate the effect of varied, gradual mixing rates of WSP on growth characteristics of turfgrasses grown on mixtures of sand, SOA, and WSP before a field application.

SM520C-TMC 강재의 피로강도에 대한 두께효과

김경남,정인수,황낙연,정경섭,Kim, Kyoung Nam,Jung, In Su,Hwang, Nak Yeon,Jung, Kyoung Sup 한국강구조학회 2004 韓國鋼構造學會 論文集 Vol.16 No.6

피로설계에 대한 기준, 시방서 또는 추천안 등은 일반적으로 두께 10~30mm의 강판으로 만든 실험체의 피로실험을 통해 얻은 피로강도곡선을 근거하고 있다. 그러나 강판의 두께가 증가함에 따라서 피로강도가 감소하게 될 가능성에 대해 관심을 갖게 되었고, 파괴역학적 방법에 의한 분석과 강재 용접에 따른 영향을 근거로 하여 강판의 두께에 따른 영향이 상당히 클 수도 있다고 지적되었다. 기존의 몇몇 피로실험 결과로부터 얻은 피로강도곡선으로부터 강판 두께에 대한 영향을 고려하여 피로강도를 수정하는 식이 제안되어왔다. 본 연구에서는, 두께 80mm까지의 국내생산 SM520C-TMC 강재에 대한 피로강도시험을 실시하고, 그 결과로부터 강재의 두께에 따른 영향을 평가하였다. 최종적으로, 강판 두께에 대한 영향을 고려하여 피로강도를 수정하는 제한적인 시편에 대한 수정식을 제공하고, 이를 기존의 연구결과와 비교 검토하였다. 결과로서, 두께에 따른 강도감소효과는 기존의 연구와 유사한 경향을 갖고 감소하나 그 정도는 적어지고 있는 결과를 얻을 수 있었다. The criterion or specification on fatigue design has been generally based on fatigue strength curve derived by tests on specimens with varying thickness (10-30mm). Making the plate thicker, however, also decreases fatigue strength. It has been noted from the test results and the results of the analysis by fracture mechanics that the effect of thickness cannot be bypassed. From the several fatigue strength curves of specimen tests, modification of fatigue strength on plate thickness has been proposed. In this study, fatigue tests on SM520C-TMC were carried out, and the effects of thickness were evaluated. Finally, in consideration of the thickness, the modification of fatigue strength was derived. Comparing the results of this paper with those of previous studies, an outline of the behavior obtained is similar to previous ones, but the rate of decrease is smaller.

Purpose: To compare the influences on the corneal endothelium and surgically induced astigmatism following cataract surgery performed with SovereignⓇ and InfinitiⓇ using the longitudinal phacoemulsification through the clear corneal incision. Methods: Patients were operated on with the SovereignⓇ (n=46) and InfinitiⓇ (n=45) programmed with the same parameters. Corneal thickness, endothelial cell count, effective phaco time and average phaco power were measured. Surgically induced astigmatism was calculated by keratometric readings. Results: The change in corneal thickness at 1 day and endothelial cell count at 1 month postoperatively was significantly lower in the InfinitiⓇ group. However, there were no significant differences in the change in corneal thickness and endothelial cell count at 2 months postoperatively. Surgically induced astigmatism in the 2 groups was consistently similar. Effective phaco time and average phaco power were lower in the SovereignⓇ group. Conclusions: Using the longitudinal phacoemulsification, early postoperative change of corneal endothelium was lower in the InfinitiⓇ group. However, the efficacy of phacoemulsification in the SovereignⓇ group was superior to the InfinitiⓇ group. J Korean Ophthalmol Soc 2010;51(3):347-352

자연 실온 및 변온 환경에서 광엽 및 세엽 훼스큐 9종류의 종자 발아력, 발아세 및 발아 피크 기간 분석

김경남,Kim, Kyoung-Nam 한국잡초학회 한국잔디학회 2017 Weed & Turfgrass Science Vol.6 No.3

본 연구는 $5-25^{\circ}C$ 조건의 자연실온에서 훼스큐 초종 간 발아력, 발아세 및 발아 피크 기간을 조사하고자 수행되었다. 자연 실온 환경에서 종자 발아력은 62.0-97.0% 사이로 나타났는데 가장 우수한 초종은 TF 'Olympic Gold' 품종으로 나타났다. 초종 간 종자 발아력은 광엽형인 TF 초종이 세엽형 보다 더 우수하였으며, 세엽형 훼스큐 초종 간 발아력은 SF>CF, HF>CRF 순서로 나타났다. 발아세의 경우 발아율이 50%에 도달할 때까지 소요되는 50% 발아세 속도부터 80% 발아세 속도까지 전체적인 초종 간 발아세 경향은 TF 초종이 가장 빨랐고 TF 다음으로는 CF 초종 이었다. 그리고 HF 및 SF 초종은 발아세 속도가 중간 정도로 나타났고, 훼스큐 속에서 발아세 속도가 가장 느린 초종은 CRF로 판단되었다. 하지만 발아환경에 따른 50% 및 70% 발아세 경향은 자연실온($5-25^{\circ}C$)보다는 ISTA 변온($15-25^{\circ}C$)에서 평균 약 4일 정도 더 빨랐으며, 실무적으로 훼스큐 종자 파종은 낮과 밤의 온도 차이가 ISTA 변온 환경에 근접할수록 바람직한 것으로 판단되었다. 훼스큐 속 초종 간 발아 피크 기간(Peak time II)은 광엽형 TF 품종이 0.73-1.84일, 평균 1.45일로 세엽형 품종 보다 더 짧게 나타났다. 그리고 세엽형 훼스큐 초종 간 발아 피크 기간은 2.16-11.15일 사이로 다양하였는데 SF<CF<HF<CRF 초종 순서로 발아 피크 기간이 점점 더 길어졌다. 본 실험결과 훼스큐 속 초종 간 발아력, 발아세 및 발아 피크 기간을 종합적으로 고려 시 자연 실온 환경에서 잔디 조성 속도의 우열 관계는 TF>CF>SF>HF>CRF 순서로 판단되었다. 전체 공시 품종에서는 TF 'Olympic Gold' 품종이 가장 우수하였고, 반대로 CRF 'Audubon' 품종이 가장 불량한 것으로 판단되었다. 즉 훼스큐 속 초종 및 품종에 따라 이러한 조성 속도 및 특성 차이가 크게 나타날 수 있기 때문에 잔디밭 조성 시 적절한 초종 및 품종 선택은 대단히 중요하다. This study was initiated to investigate seed germinating vigor, germination speed, and establishment characteristics of Festuca species under natural conditions ($5-25^{\circ}C$). Germination rate was 62.0% in CRF 'Audubon' to 97.0% in TF 'Olympic Gold'. It was greater with TF over fine-type fescues, being TF>SF>CF, HF>CRF. The germination speed, measured as days to seed germination of 50% through 80%, was fastest with TF, medium to high with CF, medium with HF and SF, and slowest with CRF. However, it was approximately 4 days slower under natural conditions, as compared with that under alternative conditions ($15-25^{\circ}C$). Germination peak time was much faster with TF. It ranged from 0.73 to 1.84 days with TF, being 1.45 days in average. But it varied with 2.16 to 11.75 days among fine-type species. The peak time was longer in order of SF<CF<HF<CRF. Considering germinating vigor, germination speed and peak time, TF 'Olympic Gold' was the best cultivar under natural conditions, while CRF 'Audubon' the poorest one. The overall establishment characteristics among Festuca species were even better with TF over fine-type fescues, which decreased in order of TF>CF>SF>HF>CRF.
