Recently the adenosinetriphosphates have massive highlight due to their high energy source for treat and maintained all the cell mechanism in the individual. When the A. T.P. release the terminal phosphate, produces about 8,000 calories instead of the 3,000 calories from common chemical bonds. The high energy-P bond enables the cell to accumulate a great amount of energy in a very small space and the keep it ready to be used as soon as it is needed. The presence of A.T.P. explains why some important cellular functions such as nerve conduction can go on for some time even with complete inhibition of respiration. In recent years the A.T.P. were used in many clinical field with good effects. In this report was used A.T.P. 20mg＋Vit $B_1$ 50mg＋20% Dextrose 20㏄ through intravenousely for E.N.T. neurologic patient, such as neurogenic hearing impairment, tinnitus, dizziness, soft palate paralysis. By the injection 40% of neurogenic hearing impairment patients were improved and 62% tinnitus patients were improved and all the soft palate paralysis patient were completely recovered.

Effects of persimmon peel powder on physico-chemical properties in 60 pigs was investigated. The pigs were randomly assigned to one of the four dietary treatments: 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 1% persimmon peel powder) 3) T2 (commercial feed supplemented with 3% persimmon peel powder) 4) T3 (commercial feed supplemented with 5% persimmon peel powder). In proximate composition, moisture of pork from treatment groups were decreased by addition level increased than that of control but crude fat was increased (p<0.05). Crude protein and crude ash was no significantly difference. The total cholesterol, HDL-cholesterol and triglyceride of treatment groups was higher than that of control.. LDL-cholesterol of control was higher than that of treatment groups. The WHC (water holding capacity) of control was higher than treatment groups and shear value was higher in treatments group (p<0.05). pH was not significantly different between control and treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05). The meat color of treatment group showed whiter and redder than that of control owing to higher L/sup */, a/sup */ and b/sup */ value. In fatty acids, stearic acid contents of treatment groups were higher than that of control. The unsaturated fatty acid/saturated fatty acid ratio of the control, T1 T2 and T3 were 1.78, 1.71. 1.69 and 1.66, respectively and control had higher than the treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05).

The purpose of the study was to identify the factors on Gatekeeper behavior of adolescents for suicide prevention. The participants were five high school students from D metropolitan city. The collected data were analysed using t-test, ANOVA, Multiple regression with SPSS 21.0 program. In the results of the study, Gatekeeper behavior showed significant difference by gender(t=2.85, p=.005), type of school(t=-2.81, p=.006), experience of significant others' suicide(t=-2.09, p=.038). Gatekeeper behavior had a positive relationship with the perception toward suicide prevention(r=.23, p=.006) and the knowledge about suicide prevention(r=.42, p<.001). In regression analysis, significant influencing factors on Gatekeeper behavior were the perception toward suicide prevention (${\beta}=.20$, p=.006) and the knowledge about suicide prevention(${\beta}=.35$, p<.001), and these variables showed 24.3% of variance. Therefore, it need to develop the intervention for improving positive perception and active knowledge about suicide prevention in adolescents. In addition, future study to identify various predictable variables is needed.

To determine the proper processing and storage conditions, physico-chemical, microbial and sensory properties of venison jerky under different dry times were measured during storage at $30^{\circ}C$ for 28 days. Samples were dried for 3 hr (T1), 4 hr (T2) and 5 hr (T3) at $75^{\circ}C$ in the smoke chamber, respectively. The pH of T1 was slightly lower than those of T2 and T3 as storage time increased. As dry and storage time increased, TBARS of T2 and T3 were significantly higher (p<0.05) than that of T1. In meat color, $L^*$ values of T3 showed slightly higher than those of T1 and T2, while at values were not clearly tendency by the passage of storage time. $b^*$ values of T2 and T3 were higher than that of T1. The water activity were significantly lower (p<0.05) in ,the order of T3$log_{10}$ CFU/g until 28 days and its number were accepted by sensory evaluation. In conclusions, T2 and T3 showed slightly high overall acceptability and lipid oxidative stability compared to T1 conditions. These results indicated that longer dry time ($4{\sim}5 hr$) of venison jerky would be better characteristics as compared to shorter dry time (3 hr) with increased storage time at $30^{\circ}C$.

Purpose: The purpose of this study was to identify predictive factors of Brest Self-Examination practice of clinical nurses. Method: The subject for this study were 277 nurses in 8 university hospitals in Busan. The data were collected from September 21 to October 20, 2001 by means of a structure questionnaire. The instruments used for this study were Choi's BSE knowledge scale. Kim's BSE attitude scale and Jung's BSE practice scale. The data were analyzed using frequency, percentage, mean, Peason Correlation, t-teat, ANOVA, scheffe's test, and multiple stepwise Regression using SPSS program. Result: 1. The mean score of BSE practice for the total sample was 7. 25${\pm}$4.62. 2. Statistically significant factors influencing the BSE Practice among social demographic characteristics were age(F=2.734, P=0.44), Married status(t=2.598, p=0.010). 3. Statistically significant factors influencing the BSE Practice among BSE relating characteristics were enlisting the help of significant peers(t=3.34, P=0.00), Intention of Practice for BSE(t=10.462, p=0.00), performance of BSE(t=7.800, P=0.00), frequency of performance in BSE(F=13.932, p=0.00), confidence in Knowledge of BSE technique(F=5.350, p=0.00), confidence in finding breast nodule(F=7.204, p=.00), asking client's BSE (t=3.153, P=0.01). 4.The mild correlation between nurse's BSE knowledge and practice was found(r=0.366,p=0.000). 5. There were significant predictors of BSE Practice. Performance of BSE was the best significant predictive factor(R2=.383, p=.000) Another significant predictive factors were knowledge, intension of practice, married status, frequency of performance. Conclusion: Degree of nurses' performance of BSE was average. It is necessary to develope the nurses' educational program for BSE with its focus on above predictive factors of performance of BSE.

The purpose of this study investigates the delivery characteristics according to the load of pollutants by calculating the delivery rate of targeted areas on pollutants in Sapkyo reservoir. The main rivers of Sapkyo reservoir are Namwoncheon, Dogocheon, Sapkyocheon, Muhancheon and Gokgyocheon. The delivery rate and their characteristics of five major rivers during rainfall season are investigated. As th result, biochemical oxygen demand (BOD), total nitrogen (T-N) and total phosphorous (T-P) of total delivery rate are calculated by 0.40, 0.34 and 0.08, respectively. The delivery rate of T-P compares to other water quality is investigated relatively low. Looked at the overall characteristics of the watershed, the delivery rate of T-N and T-P is little change in the rate of the year, too. The delivery rate of T-N is calculated from 0.2 to 0.3 in the dry season, and from 0.31 to 0.39 in a flood, respectively. The delivery rate of T-P is calculated to more than 0.3 in the dry season, and 0.11 in a flood. It is similar values which the average annual delivery rate of T-P is 0.08. Therefore, the measured delivery rate of Sapkyo reservoir can be applicable such as a delivery rate of similar features of the terrain and land use.

This study has been carried out to analized of long term changes of water quality with regard to main pollutant sources in agricultural reservoirs on the basis of data during 1996-2001. The major source was domestic wastewater(DWW) and water pollution by non-point sources(NPS) is increasing as time goes. It was determined that Seasonly average values of DWW were pH $7.6{\sim}8.7$, COD $7.0{\sim}9.4$, T-N $0.74{\sim}2.07$, T-P $0.05{\sim}0.62$, Live-stock wastewater(LWW) were pH $7.5{\sim}8.9$, COD $5.5{\sim}9.8$, T-N $0.57{\sim}1.91$, T-P $0.04{\sim}0.13$, NPS were pH $7.1{\sim}8.3$, COD $3.1{\sim}5.2$, T-N $0.29{\sim}1.44$, T-P $0.02{\sim}0.07$. Fluctuation of DWW and LWW were very wide and variable long term patterns of them were similar. Trophic states by Carlson Index of DWW and LWW was classified as eutrophic to hypretrophic from chl-a, T-P concentration.

This study is to check the applicability of SWAT-APEX (Soil and Water Assessment Tool-Agricultural Policy / Environmental eXtender) model as combined watershed and field models by applying the APEX to paddies in a watershed (465.1 $km^2$) including Yedang reservoir. Firstly, the SWAT were calibrated with 3 years (2000~2002) daily streamflow and monthly water quality (T-N and T-P) data, and validated for another 3 years (2003~2005) data. The average Nash-Sutcliffe model efficiency (ME) of streamflow during validation was 0.73, and the coefficient of determination ($R^2$) of T-N and T-P were 0.77 and 0.73 respectively. Next, running the SWAT-APEX model with the SWAT calibrated parameters for paddies, the $R^2$ of T-N and T-P were 0.80 and 0.76 respectively. The results showed that SWAT-APEX model was more correctly predicted for T-N and T-P loads than SWAT model. The difference results between watershed and field models was predicted to have substantial impact on NPS loads, especially on T-N and T-P loads. Therefore, to improve negative NPS load simulations should be considered the model characteristics as simulating mechanism to properly select the NPS model for agricultural watershed.

In an effort to enhance the lipophilicities, thereby, the penetration into the cell membrane and to increase the antitumor activities of modified derivatives of 2',3'-didehydro-3'-deoxythymidine (d4T, 1), derivatives of 1 were designed and synthesized. Starting from thymidine, 1, 2',3'-didehydro-3'-deoxythymidine-5'-phosphate, disodium salt (d4T-p, 7), and two nicotinate esters of 1; 2',3'-didehydro-3'-deoxy-5'-O-(3-pyridinylcarbonyl)thymidine (d4T-NA, 5) and 2',3'-didehydro-3'-deoxy-5'-phosphoryl-O-(3-pyridinylcarbonyl)thymidine (d4T-p-NA, 8) were synthesized. The lipophilicities of the synthesized compounds were measured by P-values and antitumor activities of those were estimated against mouse leukemia P388, murine mammary carcinoma FM3A, and human histiocytic lymphoma U937 tumor cells in vitro. Although the lipophilicities of the nicotinate esters, 5 and 8 were increased 2.75- and 9.71-fold relative to that of 1 and 7, respectively, the synthesized compounds, 1, 5, 7, and 8 were found to be inactive against P388 and FM3A cells except weak antitumor activity against U937 cell.
