지금까지 잔디밭 토양의 물리성과 화학성을 개선하여 잔디의 생육을 향상시키기 위해 많은 토양 개량재들이 사용되어 왔다. 본 연구는 돈분 50%를 주성분으로 한 새로운 유기질 개량재가 들잔디와 한지형 잔디의 생육에 어떤 영향을 미치는지 알아보고자 온실에서 수행되었다. 먼저 모래에 동물성 유기질 토양 개량재(Animal Organic Soil Amendment, AOSA)를 10%, 20% 그리고 30% 혼합한 토양의 물리성과 화학성을 분석하였으며, 각 처리구에서 들잔디와 켄터키 블루그래스의 가시적 품질과 뿌리길이를 조사하였다. 모래에 AOSA를 10~30% 혼합할 경우 토양의 화학성이 크게 개선되며 특히 20% 혼합 처리구의 유기물은 0.7%로 이는 USGA(미국골프협회)의 그린 기준에 적합한 수준이다. 또한, AOSA 30% 혼합 처리구의 유기질함량은 1.1%로 이는 들잔디 지반에 적합한 수준으로 볼 수 있다. 토양 물리성에서는, 모래에 AOSA를 혼합한 경우 투수계수가 감소하였는데 모래의 경우 높은 투수계수를 가지고 있으므로 잔디밭 토양의 투수계수를 적정 수준으로 유지하기 위해서는 AOSA를 10~30% 혼합하는 것이 바람직한 것으로 나타났다. 잔디 생육은 AOSA를 10~30% 혼합한 경우 90일까지 들잔디와 켄터키블루그래스의 시각적 품질이 모두 크게 상승하였으며 들잔디에서는 20%와 30%처리구의 뿌리길이가 좋았으며 켄터 키블루그래스에서는 20% 처리구의 뿌리길이가 크게 향상된 것으로 나타났다. 결론적으로 가시적 품질 외에 잔디의 뿌리생육, 유기물 함량 그리고 경제성 등을 종합적으로 고려한다면 들잔디에는 모래에 유기질 개량재를 20~30% 혼합하는 것이 좋고, 한지형인 켄터키 블루그래스 상토에는 20% 혼합하는 것이 적정한 혼합비율이라고 판단되었다. Many soil amendments have been used nowadays to improve physical and chmical condition of turf soil, which might ultimately optimize turfgrass growth in golf courses. This study was carried out to investigate the effects of new organic soil amendment containing pig excreta 50% and sawdust 50% on growth of zoysiagrass (Zoysia japonica L.) and kentucky bluegrass (Poa pratensis L.) in greenhouse. Three applicable treatments with soil mixtures of 10, 20, and 30% (v/v) animal organic soil amendment(AOSA) with sand, were tested for chemical property, physical property, visual quality and root length of zoysiagrass and Kentucky bluegrass. As results, application of 10~30% AOSA mixtures were proper to grow turfgrass in soil nutrition. Especially, the treatment with 20% AOSA mixtures showed 0.7% in organic matter, which meets to green standard of USGA. Also, 30% AOSA mixtures was 1.1% in organic matter, which might be desirable for zoysiagrass-planted golf courses in Korea. It was turned out that addition of AOSA decreased the hydraulic conductivity in soil physical property. Because the sand possess high hydraulic conductivity, it is recommended to combine 10~30% AOSA with sand in order to sustain soil balance. The treatment with 10~30% AOSA noticeably increased visual quality of both zoysiagras and Kentucky bluegrass during 90 days. However, treatments with either 20% or 30% AOSA were effective to develop root length of zoysiagrass but treatments with 20% AOSA were more effective than that of 30% AOSA mixtures to promote root length of Kentucky bluegrass at 60 days. In conclusion, considering all vital factors such as visible quality, root growth, organic matter content, and economical efficiency, was taken, it is recommended that a 20~30% mixture of AOSA with sand is good for the growth of zoysiagrass and 20% mixture for Kentucky bluegrass.

우리나라에서 벌초는 추석 성묘와 시향에 앞서 이루어지는 매우 중요한 행사이다. 벌초는 보통 추석 1-2주 전에 집중해서 이루어지기 때문에 전국적으로 도로의 교통체증이 심해지고 안전사고의 발생도 점점 많아지고 있다. 잘못된 벌초 방법은 흙이 드러나 토양 유실을 유발하거나 묘지 잔디의 밀도 저하와 잡초 발생의 원인이 되기도 한다. 다라서 벌초시기의 분산과 올바른 벌초 방법은 매우 중요한 문제일 수 있다. 본 연구에서 벌초 시기는 추석 1주전, 2주전, 3주전, 4주전 잔디 깍기 처리를 두었고, 벌초 방법에서는 잔디 깍는 높이를 달리하여 들잔디와 금잔디의 생육에 미치는 영향을 평가하였다. 들잔디에서 추석과 시향 시기를 기준으로 잔디 깍기 시기는 빠를수록 초장이 길었으나 피복률과 밀도는 높은 경향이었다. 금잔디에서 잔디 깍기 시기는 빠를수록 초장이 길었으나, 피복률과 밀도는 각각 차이가 없거나 일정한 경향을 보이지 않았다. 들잔디에 비해서 금잔디의 초장은 잔디 깍기 시기에 관계없이 짧게 유지되었으며 피복률과 밀도도 높게 유지되었다. 벌초는 들잔디와 금잔디 모두 짧게 할 수록 초장이 짧아졌고, 피복률과 밀도도 낮아졌다. 또한 벌초 시 들잔디와 금잔디는 각각 지상부의 40-50 mm or 30-40 mm 남겨둘수록 묘지 잔디의 밀도유지에 유리한 것으로 나타났다. In Korea, mowing the grass of a grave (Beolcho) is a very important event preceded by Chuseok (Korean thanks giving day) and Si-Hyang (annual ancestral feast). Because Beolcho usually takes place one or two weeks before Chuseok, the traffic accidents on roads are getting worse and safety accidents are getting more and more. Erroneous Beolcho methods can cause the soil to be exposed and cause the loss of soil or the low shoot density of graveyard grass or weed occurrence. Therefore, the dispersion of the Beolcho timing and the approprite method can be import issues. The present study assessed the effects of grass mowing timing and height before Chuseok on the growth of Zoysia japonica and Z. matrella. The mowing timing was evaluated at 1 week, 2 weeks, 3 weeks, and 4 weeks before Chuseok, and the mowing height differently according to the two type of grass. In Z. japonica, the faster mowing before Chuseok, the longer the plant height, and the coverage rate and shoot density were higher. In Z. matrella, the faster mowing, the longer the shoot length, but the coverage rate and shoot density did not show any difference or tendency. As compared to Z. japonica, the plant height of Z. matrella was kept short regardless of the time of mowing. In both grasses, the plant height was shortened when mowing was done at low cutting height, but the coverage rate and shoot density were decreased. In addition, it was shown that it is advantageous to maintain the shoot density of graveyard lawn by 40-50 mm or 30-40 mm cutting above the ground for Z. japonica or Z. matrella, respectively.

마크로고리 화합물을 운반체로 하는 액체막을 통한 이온의 운반에 관한 연구 (제1보). Dibenzo-18-Crown-6-(DBC)/$H_2O-CHCl_3-H_2O$계에서 칼륨이온의 운반 메카니즘

칼륨이온이 dibenzo-18-crown-6(DBC)에 의해 $H_2O-CHl_3-H_2O$액체막을 통하여 운반되는 속도를 10가지 칼륨염의 농도를 변화시키면서 $25^{\circ}C$에서 측정하였다. 운반속도는 농도와 음이온의 특성에 크게 의존했으며 농도효과로 부터 피크르산칼륨의 경우에는 이온쌍 형성으로 인하여 1.0 ${\times}10^{-3}$M을 전후하여 각기 다른 양상을 보였다. 이온의 운반과정은 다단계 착물반응 및 확산과정에 의한 것으로 운반 메카니즘을 체계화하기 위해 비균질성 액체막의 각상에서 갖는 화학종의 에너지 장벽모델을 제시하였다. 또한 이를 음이온의 수화자유 에너지와의 관계를 비교함으로써 새로이 7단계 운반과정을 제시하고 그 운반 메카니즘을 고찰하였다. The transport rates of $K^+$ion through CHCl$_3$ liquid membrane containing dibenzo-18-crown-6(DBC) as a carrier molecule have been determined at $25^{\circ}C$. The transport rates depend highly on the ion concentration and on the nature of anion. It is concluded that $K^+$ions are transported in the form of ion-pair. In the case of potassium picrate, however, it is found that the transport proceeds with the formation of the incomplete ion-pair in the concentration less than 1.0 ${\times}10^{-3}$M of picrate, while with the complete formation of ion-pair in the concentration more than 1.0 ${\times}10^{-3}$M of picrate. Seven steps of the transport process are suggested and they can be illustrated in terms of energy barrier model as a function of the position of ionic species in the membrane.

Semi-Rigid 연결체의 특성을 고려한 강구조물의 정·동적 해석

구민세(Min Se Koo),양창현(Chang Hyun Yang),신동기(Dong Ki Shin) 한국강구조학회 1993 韓國鋼構造學會誌 Vol.5 No.2

In this research, the behavior of steel structures including the characteristics of semi-rigid connections was analyzed by computer simulation under artificially generated earthquake loading since the experimental study for the whole structures is almost impossible in the current situation. From the results of analyses for the 1, 2 and 3-story structural models dealt in this research, the lateral rigidity of steel structures with characteristics of semi-rigid connection was less than that with characteristics of rigid connections in the elastic zone. On the other hand, the ductility factor in the case of semi-rigid connections increased. The ductility factor is important for accuracy of earthquake resistance design by the equivalent static analysis and the response spectrum analysis. Therefore, these facts can be explained by that the classical method supposing semi-rigid connections as rigid body for the elastic design of steel structure could be unstable. And over-estimate design in the case of semi-rigid connections is expected by higher ductility factors and by decreasing of magnitude of response spectrum due to the increment of natural period. The result of this research shows that there is difference between the behaviors of steel structures considering semi-rigid and rigid connections. Therefore, it can be concluded that the characteristics of the semi-rigid connections are very meaningful by increasing necessity of more accurate analysis of structures.

The objectives of this study are as follows:First, to examine the effects of Diary Education Program using the BrailleDisplay on the writing length and accuracy of blind children. Second, to examine the effects of Diary Education Program using the Braille Display on the quality of writing of blind children. Third, to examine the effects of Diary Education Program using the Braille Display on blind children``s attitudes toward writing. In order to conduct it 3 blind children(1 girl and 2 boys) from the 4th grade of C School for the Blind were selected as the subject for this study. The experiment covered the period from April 12, 2004 to September 16, 2004. Before taking Diary Education Program using the Braille Display, blind children took the pretest. Then, over two weeks, they were taught how to use the Braille Display. In preparation, the children were trained 20 times using the braille display for word processing before being assessed. After blind children became familiar with the device, blind children started training of Diary Education Program using the Braille Display for 20 sessions. After blind children finished the training, they were tested in the 2nd week. They were tested yet again in the 5th week and 8th week to see if their results were maintained. By using the results of the tests, (before and after blind children took the Education Program) the length, accuracy, and quality of the writing and children``s attitudes toward writing were analyzed. The writing length was measured by the quantity of words and sentences, the writing accuracy by the orthography and the accuracy of word spacing and writing quality by an evaluation checklist. The children were asked to fill out a survey to find out their attitudes toward writing. They were asked questions about their writing related to cognitive, response and process The results of this study are summarized as follows: First, Diary Education Program using the Braille Display improved the length and accuracy of blind children``s writing.Second, Diary Education Program using the Braille Display improved the quality in writing content, organization and quality of expression of blind children``s writing. Third, Diary Education Program using the Braille Display improved blind children``s cognitive appreciation about writing, their emotional responses toward writing and children``s attitude toward writing process, thus changing blind children``s writing attitude very positively. This study showed that Diary Education Program using the Braille Display was effective in improving the writing skills of blind children and changing their attitudes toward writing positively. A formal evaluation system based on the above results should be designed to accurately conduct research about children being trained in writing and Diary Education Program using the Braille Display.

Tsutsugamushi disease is acute febrile illness primarily affecting farmer and prevalent in Autumn. The disease is characterized by fever, rash and eschar and sometimes it caused atypical pneumonitis and it should be differentiated by Leptospirosis and Korean hemorrhagic fever. We experienced 38 cases of Tsutsugamushi disease diagnosed by clinical and detection of tsutsugamushi antibody by indirect immunofluorescent technique. Studied subjects were 15 cases of male and 23 cases of female and the victim were primarily farmer(89%). Most cases were occurred in October and September and in 1990. Fever and chills(94%)were the most complaint symptoms and other complaint symptoms were myalgia cough and dyspnea in the order of frequency. Leuhocytosis or leukopenia was detected in 14% and 11% respectively and 83% were detected to have thrombocytopenia. Transaminase was elevated in 57% and BUN and creatinine was elevated in 3%. Physical examination showed eschar(84%), rash(82%) hypatosplenomegaly(24%),conjunctival injection and hyperemia of pharynx. chest X-ray showed interstitial pneumonitis (11%) pulmonary edema(11%) and cardiomegaly(8%). 57% were revealed positive reaction to indirect fluorescent antibody technique. Clinical response was very good in the treatment of tetracycline vibramycin, or chloramphenicol.

The rate of identifying microorganisms using large volume culture from peritoneal dialysate was evaluated among 149 episodes of clinical peritonitis during CAPD managed in the Soon Chun Hyang University Hospital, Seoul, Korea. Three groups of different volumes were compared: group Ⅰ: 1000 ml divided into 4 equal volumes (n=52), group Ⅱ: 600 ml divided into 2 equal volumes of 250 ml and 50 ml (n=52), group Ⅲ, 200 ml divided into 4 equal volumes (n=45). The results were as follows: The overall rate of identification was 49.3% (73/149). In group Ⅰ, rate of identifying microorganisms was 57.7%, in group Ⅱ 52.4% and in group Ⅲ 31.1% respectively (P<0.05, group Ⅱ versus group Ⅲ). Among the isolates, 49.2% were gram positive bacteria, 12.2% gram negative rods and 13.8% fungi. The most frequent isolate was Staphylococcus aureus. (28.7%) The identifying rate in the dialysate with leucocytes more than 100/m㎥ was 52.4% as compared with 41.3% less than 100/m㎥. These results suggest that large volume culture of the dialysate is superior to the small volume (conventional 10 ml) culture.

The macrocyclic ligands with N_2O_2 donor sets, such as 3, 4 : 9, 10-dibenzo-1, 12-diaza-5, 8-dioxacyclotetradecane (Oen-Nen-H_4), 3, 4 : 9, 10-dibenzo-1, 12-diaza-5, 8-dioxacyclotetradecane (Oen-Ntn-H_4), 3, 4 : 10, 11-dibenzo-1, 13-diaza-5, 9-cyclopentadecane (Otn-nen-H_4) and 3, 4 : 10, 11-dibenzo-1, 13-diaza-5, 9-dioxacyclohexadecane (Otn-Ntn-H_4) have been synthetized as the reported method, while the synthetic method of 3, 4 ; 10, 11-dibenzo-1, 8-diaza-5, 12-dioxacyclotetradecane (Trans Mcen-H_4) were devised. Dioxouranium (Ⅵ) complexes with the ligands have been characterized in methanol solution by UV-Vis-and IR-spectrophotometry, and the protonation constants of the ligands and the stability constants of the complexes have been determined by potentiometry at 25℃ with a empirical equation ??/??-1) M=(2-??) Mβ_2(??-1)-β_1. The compositions of the complexes are (UO_2^2+)_2 (Oen-Nen-H_4), (UO_2^2+) (Oen-Ntn-H_4), UO_2^2+(Otn-Nen-H_4), (UO_2^2+) (Otn-Ntn-H_4) and (UO_2^2+)_2 (trans Mean-H_4). For the complexes, the stabilities reach a peak at the 16-membered ring complex, and consideration of structural factors suggests that each ligand is tetradenate to dioxouranium (Ⅵ) ion in which two oxygen and two nitrogen atoms coordinate to metal ion respectively and that Trans-N_2O_2 system ligand forms more stable complex than Cis-N_2O_2 system ligand.

Continuous ambulatory peritoneal dialysis has become an acceptable alternative to hemodialysis for the patients of chronic renal failure in recent years. In spite of diverse benefits of continuous ambulatory peritoneal dialysis, it has a relatively troublesome problem of peritonitis. Common bacteria, namely, staphylococcal species, are the usual caustive agents. Fungi and higher bacteria such as Nocardia are not usual as etiologic agents in peritonitis undergoing peritoneal dialysis. We report one case of peritonitis caused by Nocardia associated with peritoneal dialysis with a review of literature.
