광산 주변 경작지의 일부 농산물에 대해 오염 실태를 파악하고 폐광산에 의한 오염방지 및 사후관리 대책 수립에 필요한 기초자료를 제공하기 위하여 전남 지역에 분포한 광산지역 (4개 지역)을 대상으로 주변 경작지에서 7종의 농산물 (상치, 양파, 감자, 무, 고추, 호박, 콩) 28건에 대해 미량금속 함유량을 조사하였다. 수은의 경우 대부분의 검체에서 불검출이었으며, 일부 농산물에서 0.01 ppm이하의 정도로 검출되었다. 비소는 28건의 시료 중 8건에서 0.012 ~ 0.029 ppm이 검출되었으며 나머지 시료는 불검출이었다. 납은 양파를 제외한 다른 시료에서 미량 검출되었고, 함유량은 N. D. ~ 0.114 ppm 있었으며, 카드뮴은 거의 모든 시료에서 검출되었으며 (N.D. ~ 0.124 ppm), 수은, 비소, 납, 카드뮴 등의 함유량은 오염된 수준이 아닌 자연 함유량 수준으로 판단된다. 구리의 경우 두류인 콩에서 3.070 ~ 7.825 ppm으로 다른 시료에 비해 높은 함유량을 나타냈으며, 광산 지역간에는 큰 차이를 보이지 않았다. 망간은 상치 (3.688 ~ 23.935ppm)가 가장 높은 함유량을 보였으며, 아연의 경우 콩과 상치에서 높은 함유량을 나타냈다. To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of heavy metal and trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of argicultural products (lettuce, onion, potato, radish, pepper, pumpkin, bean) collected from 4 unworked mines locate in Chollanam-Do in2001 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd, Cu, Mn, and Zn. Hg contents were detected N.D. ~ trace level (0.01 ppm and less) and As content were detected N.D. ~ 0.029 ppm but most of samples were not detected. Cd contents were detected N.D ~ 0.124 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to post health problems. The average contents of Cu were 3.070 ~ 7.825 ppm in bean, the Mn were 3.688 ~ 23.935 ppm in lettuce and the Zn were 5.690 ~ 21.171 ppm in bean, respectively.

Soft chelating irrigation이 GP/AH Plus로 충전된 근관의 sealing ability에 미치는 영향에 대한 평가

유이숙,김태균,이광원,유미경 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.6

본 연구의 목적은 glucose leakage test를 이용하여 soft chelating irrigation이 근관 충전의 sealing ability에 미치는 영향을 평가하는 것이다. 발치된 45개의 단근치를 수집하여 치관부를 잘라내 치근이 총 13mm가 되게 하였다. 근관은 K3 NiTi 구동 기구를 사용하여 성형하고 #45/.06 taper까지 확대하였다. 3개의 실험군(n=13)과 2개의 대조군(n=3)으로 나누었다. 실험군은 다음의 세척 방법으로 처리하였다. 1군, 2.5% NaOCl로 세척; 2군, 2.5% NaOCl로 세척 후 17% EDTA로 최종 세척; 3군, 2.5% NaOCl과 15% HEBP 혼합 용액으로 세척, 근관은 gutta-percha와 AH Plus를 사용하여 측방가압으로 충전하였다. , 습도 100%에서 7일 동안 보관하고 glucose leakage model을 이용하여 치관부로부터 치근부 방향의 미세누출을 정량화하였다. 1, 4, 7, 14, 21, 28일 째 누출된 glucose의 농도를 spectrophotometry로 측정하였다. 분석 결과 모든 실험군에서 실험 기간 동안 누출이 증가하는 경향이 있었다. HEBP처리군은 실험 기간 동안 EDTA처리군과 유의한 차이를 보이지 않았다. HEBP처리군은 21일 이후부터 도말층으로 덮인 NaOCl처리군에 비해 유의하게 낮은 누출을 보였다. HEBP로 처리된 상아질은 EDTA로 처리된 상아질과 비슷한 양상의 폐쇄를 보였으나 도말층이 남아있는 상아질보다는 우수한 sealing ability를 나타냈다. 그러므로 약한 킬레이트제인 HEBP는 EDTA의 대안이 될 수 있을 것이다. The purpose of this study was to evaluate the effect of soft chelating irrigant on the sealing ability of root fillings by using a glucose leakage test. A total of 45 single-rooted teeth were selected for the study. The teeth were decoronated leaving a total length of 13mm. The root canals prepared using K3 NiTi rotary instruments to an apical dimension of size 45(0.06 taper). The specimens were then randomly divided into 3 experimental groups of 13 roots each and 2 control groups of 3 roots each. Specimen in each group were prepared with different irrigation protocols : group 1, 2.5% NaOCl; group 2, 2.5% NaOCl and 17% EDTA: group 3, 2.5% NaOCl and 15% HEBP. The root canals were filled with gutta-percha and AH Plus sealer using lateral condensation. After 7 days in , 100% humidity, the coronal-to-apical microleakage was evaluated quantitatively using a glucose leakage model. The leaked glucose concentration was measured with spectrophotometry at 1, 4, 7, 14, 21 and 28 days. There was a tendency of increase in leakage in all experimental groups during experimental period. HEBP-treated dentin showed no significant difference with EDTA-treated dentin during experimental period. From the 21th day onward, HEBP-treated dentin showed significantly lower leakage than smear-covered dentin. HEBP-treated dentin displayed a similar sealing pattern to EDTA-treated dentin and a better sealing ability than smear-covered dentin. Consequently, a soft chelator(HEBP) could be considered as the possible alternative to EDTA.

The studies were intended to clarify the correlations between the characters and the influences upon yields of some sweet potatoes. The analysis of covariance was used to obtain genotypic correlations and phenotypic correlations among the eight characters such as stem-length, stem-number, stem-diameter, node-number, stem-weight, underground weight, root-number and root-weight, and the path-coefficients were calculated by Dewey's method. The results obtained are summerized as follows; 1. The yield of sweet potatoes was mainly associated with the characters such as stem-length, stem-number, node-number, stem-weight, undergroundweight, etc. 2. Node-number, stem-weight and underground-weight have positively influenced directly upon the yield of sweet potatoes. 3. Stem-length, stem number and root number also had little or negative influences upon yield but it had rather considerable indirect influence upon yield by increasing of sweet potatoes. 4. As a result, it can be concluded that the yield of sweet potatoes is determined underground weight, node number and stem number etc.

Purpose: This study was to prepare the basic data for prevention of colo-rectal cancer and protection against its spread. Method: The subjects for the study were 204 patients with colo-rectal cancer from the G.S. wards of five general hospitals in Busan for the period of June 1 to September 1, 2001. The instrument used was questionaire which was developed by Junho Shin(1995). The data was analyzed by descriptive statistics, McNemar test, x^2 test, paired t-test, and ANOVA. Result: 1. 57% of the studied subjects were male, 42.7% were more than 60 years old, 54.9% were of standard physique, 49.5% were the Buddhists, 50.5% were the middle or high school graduates. 83.8% were city dwellers, 48% were jobless, 69.6% had no-history of alimentary disease, 44.1% had no-family history of cancer, 82.8% were married. 2. Constipation (x^2=36.45, p=0.0001) in clients showed a significant positive association for the pre-diagnosed, but diarrhea(x^2=3.947, p=0.047)showed a significant positive association for the post-diagnosed. The preference for high seasonings(t=6.23, p=0.0001) and animal fat (t=8.35, p=0.0001) was higher significantly in the pre-diagnosed, but physical activities(x^²=30.22, p=0.0001), an eutrophic or tonic medicine(x^2=30.22, p=0.0001), was of and vegetables(t=-6.20, p=0.0001) was higher significantly in the post-diagnosed. 3. There were significant differences in the life style of the pre-diagnosed according to the general characteristics except religion. Conclusion: Results of the above study reveal we should be very sensitive to the change of defecation styles and consider the necessity of improving life styles as regards eating habits. When an education program is developed, the general characteristics of the subjects need to be considered.

韓鏡秀,張權烈,高美錫 진주농과대학 1970 진주농과대학 연구논문집 Vol.- No.9

小豆의 收量에 影響하는 形質을 正確히 알기 爲하여 形質相互間의 相關關係 그리고 經路係數分析과 各形質相互間의 表現型共分散, 遺傳共分散, 環境共分散 등을 計算하고 여러가지 選拔指數를 作成하여 選拔實驗을 한바 그 結果를 要約하면 다음과 같다. (1) 各形質相互間의 表現型共分散의 값보다 遺傳共分散의 값이 大體로 크고 環境共分散은 그 값의 變動이 甚하다. (2) 遺傳相關의 값이 表現型相關보다 높으며 開花日數와 1株重量, 莖長과 1株重量, 莖直徑과 分枝數, 莖直徑과 1株重量, 莖直徑과 100粒重, 分枝數와 1株重量, 1株重量과 100粒重間에는 높은 正의 相關을 보였고 收量과는 莢數만이 높은 正의 相關을 보였다. (3) 收量에 미치는 諸形質의 直接的 影響을 보면 莢數, 莖直徑, 100粒重, 莖長, 開花日數의 順으로 收量에 正으로 影響하며, 間接的 影響을 보이는 形質은 主로 莢數는 分枝數의 增加로 收量에 間接的으로도 影響하는 것을 알수 있다. 그리고 莖直徑은 開花日數, 莢長, 分枝數, 1株重量, 100粒重과 間接的으로 作用하여 收量에 影響하고 1株重量은 莖直徑, 莢數, 100粒重의 3形質과 100粒重은 開花日數, 莖直徑, 分枝數, 1株重量, 100粒重과도 間接的으로 影響을 미치는 것을 알수 있다. (4) 各形質을 選拔對象 形質로 하여 選拔指數를 作成한바 第3表 및 第4表와 같이 形質의 組合에 따라서 選拔에 관여하는 各形質의 加重値(weight)는 다르나 부호는 大體로 同一하다. (5) 選拔指數에 依한 遺傳的 進展과 그의 關係效率을 본바 單一形質에 있어서는 莢數, 1株重量, 100粒重의 效率이 높고 單一形質보다 2個形質을 2個形質보다 3個形質을 選拔對象形質로 하여 選拔하는 것이 效果的이라는 것을 알수 있다. 以上의 結果를 미루어 보아 小豆의 形質中 莖長, 莖直徑, 莢數, 100粒重의 4個形質이 收量에 直接 또는 間接으로 影響하는 重要形質이 될 수 있을 것으로 믿는다. 그리고 小豆에 있어서는 莖長(X₂), 莖直徑(X₃), 莢數(?), 100粒重(??)의 4個形質中에서 2-3形質을 選拔對象形質로 하여 選拔指數를 作成하여 選拔에 應用하는 것이 時間과 勞力 그리고 選拔效果面에 있어서 效果的일 것으로 믿는다. The studies were intended to clarify the correlations between the characters and the influences of each character upon yield of Adzuki beans. The analysis of covariance was conducted to obtain the genotypic correlations among eight characters-days to flowering, stem length, stem diameter, number of branches per plant, number of pods per plant, plant weight, 100 grain weight and grain weight(yield), etc., and the path-coefficients were calculated by Dewey's method. Selection indexes were calculated by phenotypic and genotypic covariances between the characters, and genetic advances and relative efficiency were also calculated for these characters. The results obtained are summarized as follows: (1) The yield of Adzuki bean was mainly associated with the character, number of pods per plant. (2) The values of genotypic covariances were slightly higher than those of phenotypic covariances between the characters. (3) Stem length, stem diameter, number of pods per plant, and 100 grain weight had a direct positive influence upon the yield of Adzuki beans. (4) Number of branches per plant and total plant weight had little or negative influences upon yield but it had rather considerable indirect influence upon yield by increasing the other characters. As a result, it can be concluded that Adzuki bean yield is primarily determined by increasing number of pods per plant, in turn the yield of Adzuki bean is secondarily determined by the number of pods per plant. (5) Many selection indexes which contain 1-7 characters in calculation were obtained as shown in Tables 2 and 3, and they show the genetic advances and relative efficiency which were calculated with various selection indexes. These results suggest that selection index technique is useful in Adzuki bean breeding. In reality, however, as the selection index varies with population and environment in which the population is located. Inspite of the expected usefulness of selection index technique in Adzuki bean breeding, unsolved problems such as the expense, time and labor involved in calculating the selection index remain. For these reasons and from these studies, it was realized that the selection index for the selection should be calculated on the basis of the data of some 3-4 characters, stem length, stem diameter, number of pods per plant, and 100 grain weight, etc. These characters should be very useful agronomic characters in the selection of Korean Adzuki beans, as they could be measured or counted easily thus saving time and expense, and have a greater effect on more Adzuki bean yield than the other agronomic characters.

Abstract. This study set out to research preference of flowers, to analyze the impacts of floral decoration on the improvement of recognition ability in the demented old adults in order to develop an more effective horticultural therapy program for the demented old adults. The subjects were made out of the demented old adults who were taken care of at <HABIT Demented Old Adults Day Care Center> located in Icheon-dong, Nam-gu, Daegu Metropolitan City. Total six subjects were included in experiment. They were all female, and their average age was 76. The experiment was conducted once a week from February 14 to May 9, 2002, total in 12 times. The experiment was only focused on floral decorations. The color and size of flowers were considered to decide the subjects preference. The subjects preferred red and yellow flowers. They also liked big flowers or small but opulent ones. As for floral decoration, the material flowers were different each session. But the subjects were aroused into interest via repetitive activities such as designing their works and arranging, cutting, and putting in flowers. Their active and confident attitudes became evident, and their relationships with their family grew better as they shared their works with them.
