Purpose: The purpose of this study was to investigate the relationship between self concept and the climacteric symptoms in middle-aged women. Method: From a convenience sample of 123 women between 40 and 59 years of age living in P-city data were collected using a structured questioanaire. It included a self concept scale and climacteric symptom scale. With spss/pc(+), data were analyzed using descriptive statistics, t-test, ANOVA and Pearson's correlation coefficients. Result: 1 The mean score for self concept was $108.73{\pm}16.24$. 2. The variables that influenced the self concept of middle-aged women most were 'health state' and 'marriage satisfaction'. They were statistically significant at the .01 level. 3. The mean score for climacteric symptoms was 3.13. Of psychophysical, physical and psychological symptoms the scores for psychophysical symptoms were the highest. 4. There were significant negative correlations between self concept and climacteric symptoms (r=-.333, p=.000). Conclusion: This study suggests that positive self concept can reduce climacteric symptoms in middle-aged women.

The use of aluminum-based coagulants in water pretreatment is being carefully considered because aluminum exposure is a risk factor for the onset of Alzheimer's disease. Lightly burned-dolomite kiln dust (LB-DKD) was evaluated as an alternative coagulant because it contains high levels of the healthful minerals calcium and magnesium. An organic pore forming agent (OPFA) was incorporated to prepare porous granules after OPFA removal through a thermal decomposition process. A spray drying method was used to produce uniform and reproducible spherical granules with low density, since fine dolomite particles have irregular agglomeration behavior in the hydration reaction. The use of fine dolomite powder and different porosity granules led to a visible color change in raw algae (RA) containing water, from dark green to transparent colorlessness. Also, dolomite powders and granules exhibited a mean removal efficiency of 48.3% in total nitrogen (T-N), a gradual increase in the removal efficiency of total phosphorus (T-P) as granule porosity increased. We demonstrate that porous dolomite granules can improve the settling time and water quality in summer seasons for the emergent treatment of excessive algal blooms in eutrophic water.

This descriptive study was done to identify factors influencing sexual satisfaction in women who had had a hysterectomy and to compare these with women who had not had a hysterectomy. The purpose was to contribute theoretical understanding on which to base nursing care planning. One group of subjects were 156 women who had had a hysterectomy, between one and 18 months post surgery, living with their spouse, having no complications, and menstruating before surgery. The other group of subjects were 282 healthy women who were living with their husbands and menstruating. The study tool consisted of 108 items including item concerning personal characteristics, characteristics related to the hysterectomy, husband's support, body image, emotions, attitude toward the sexual relationship, knowledge of sexuality, sexual behavior, and sexual satisfaction. Sexual satisfaction was measured by a tool based on Derogatis Sexual Function Inventory. The range of the internal level of the study tool was from. 5208 to .9462. Data collection was done during the period from June 20 to Aug.20, 1989. The same questionnaire was used of data collection for both groups, but a mail survey method was used for the women who had had a hysterectomy, and an interview method was used for the women who had not had a hysterectomy. Data analysis was done using frequency, ratio, mean and S.D. for the characterstics of the subjects and level of sexual satisfaction. t - test or ANOVA was used for the differences between the groups with regard to the general and hysterectomy related characteristics. The relationship between the score for sex life related factors and the level of sexual satisfaction was analyzed using the Pearson Correlation, and the influencing factors on sexual satisfaction were analyzed by stepwise multiple regression. The results of this study were as follows ; 1. Mean age and income level were the only general characteristics for the two groups that were significantly different. The mean age, and income level of the group who had had a hysterectomy were 45years, and 1,150,000 won respectively, and for those who had not had a hysterectomy, 41 years and 999,000 won. 2. There was no statistical difference of the sexual satisfaction score between the two groups. 3. There was differences in the factors influencing sexual satisfaction between the two groups. Factors influencing sexual satisfaction for the group who had had a hysterectomy were husband's support (R＝.5793, P＝.000) and the women's Knowledge of sexuality(R＝.6670, P＝.000) (total variance : 33.56). On the other hand, emotional status(R＝.4294, P＝.000), sexual behavior(R＝.4294, P＝.000), husband's support(R＝.5274, P＝.000) and attitude towards sexual relations (R＝.5412, P＝.000) (total variance : 54.12) were the factors influencing sexual satisfaction in the group who had not had a hysterectomy. Since husband's support and sexuality knowledge were identified as factors influencing sexual satisfaction of women who have had a hysterectomy, it can be concluded that, before a woman who has had a hysterectomy is discharged from hospital, nurses should include strategies in the nursing care plan that will promote husband's support and the women's knowledge of sexuality.

This study examined and identified the relationship between the level of hope and self-care agency in hemodialysis patients. The purpose of the study was to reveal that hope is an essential factor to enhance self-care agency and to prepare the basic materials to help nurse the patients. The subjects for this study consisted of 108 persons who undergoing hemodialysis from 2 hospital, 2 hemodialysis center in Pusan, Korea. The degree of hope was measured by the questionnaire that has been developed by Miller. The self-care agency was measured by the questionnaire that has been developed by Kearney B.Y & Fleisher B.J. The collected data were analyzed by descriptive statistics and t-test. one-way ANOVA and Pearson's Correlation Coefficient with SPSS WIN program. Results were obtained as follows: 1) The mean scores of hope were $131.77{\pm}25.77$(range 67-195). The rate of hope classified said that the lowest hope was 2.8% and low hope was 27.8%. 2) The mean scores of self-care agency were $143.78{\pm}23.63$(range 74-187). The degree of self-care agency classified said that the rate of self-care agency deficiency was 0.9% and low self-care agency was 12.0%. 3) The hope was significantly related to self-care agency. That is, the higher the hope score was， the higher the level of self-care agency score(r=0.668，p=0.001) was. In this result, there were hemodialysis patients who have very low hope score and self-care agency score. In this cases self-care agency can be increased by encouraging the patients to be more hopeful. Conclusively nurses should access the degree of hope and self-care agency of hemodialysis patients individually and apply the hope therapy in order that the patient have higher hope than before.

A study for the assessment of natural environmental radiation exposure at a flat and open field of about $10,000m^2$ in area in CNU Daeduk campus has been carried out by means of gamma-ray scintillation spectrometry and thermoluminescence dosimetry for one year period of time from October 1984. The detectors used were 3'${\phi}{\times}$3' NaI(T1) and two different types of LiF TLD, namely, chip sealed in plastic sheet which tightly pressed on two open holes of a metal plate and Teflon disk. Three 24-hour cycles of in-situ spectrometry, and two 3-month and one 1-month cycles of field TL dosimetry were performed. All the spectra measured were converted into exposure rate by means of G(E) opertaion, and therefrom exposure rate due to terrestrial component of environmental radiation was figured out. Exposure rate determined by the spectrometry was, on average, $(10.54{\pm}2.96){\mu}R/hr$, and the rates of $(12.0{\pm}3.4){\mu}R/hr$ and $(11.0{\pm}3.6){\mu}R/hr$ were obtained from chip and disk TLD, respectively. Fluctuations in diurnal variation of the exposure rate measured by the spectrometry were noticeable sometime even in a single cycle of 24 hours. It is concluded that appropriately combined use of TLD with iu-sitn gamma-ray spectrometry system can give more accurate and precise measure of environmental radiation exposure, and further study for more adequate and sensitive TLD for environmental dosimetry, including improvement and elevation of accuracy in data assessment through inter-laboratory or international intercomparison is necessary.

Purpose: This study was performed to develop a valid and reliable Korean Patient Classification System for Neonatal care nurses (KPCSN). Methods: The study was conducted in tertiary and general hospitals with 1~2 grade according to nursing fee differentiation policy for NICU (neonatal intensive care unit) nurse staffing. The reliability was evaluated for the classification of 218 patients by 10 nurse managers and 56 staff nurses working in NICUs from 10 hospitals. To verify construct validity, 208 patients were classified and compared for the type of stay, gestational age, birth weight, and current body weight. Nursing time was measured by nurses, nurse managers, and nurse aids. For the calculation of conversion index (total nursing time divided by the KPCSN score), 426 patients were classified using the KPCSN. Data were collected from September 5 to October 28, 2015, and analyzed using t-test, ANOVA, intraclass correlation coefficient, and non-hierarchial cluster analysis. Results: The final KPCSN consisted of 11 nursing categories, 71 nursing activities and 111 criteria. The reliability of the KPCSN was r=.83 (p<.001). The construct validity was established. The KPCSN score was classified into four groups; group $1:{\leq}57points$, group 2: 58~80 points, group 3: 81~108 points, and group $4:{\geq}109points$ in the KPSCN score. The conversion index was calculated as 7.45 minutes/classification score. Conclusion: The KPCSN can be utilized to measure specific and complex nursing demands for infants receiving care in the NICUs.

Purpose: The purpose of this study was to identify post-operative discomfort, sense of loss, family support, and resilience in breast cancer surgery patients, and to investigate factors that affect resilience. Method: The sample of this study consisted of 108 patients who underwent surgery for breast cancer in two university hospitals located in B city. The collected data was analyzed with descriptive statistics, t-test, ANOVA, and Scheffé test, Pearson's correlation coefficients, and hierarchical multiple regression. Results: The factors that significantly affected resilience were as follows: having a religion (${\beta}=-.20$, p=.006), having an occupation (${\beta}=.14$, p=.049), having a high school diploma (${\beta}=.31$ p=.001), making less than 2-3 million won (${\beta}=-.19$, p=.036) per month, experiencing a sense of loss (${\beta}=-.22$, p=.003) and family support (${\beta}=.44$, p<.001). The total explanatory power amounted to 53.8% (F=14.83, p<.001, $AdjR^2=.54$). Conclusion: Educational intervention programs for breast cancer surgery patients that improve resilience by reducing the sense of loss and increasing family support must be developed.

We have cloned and analyzed cDNA coding for non-virion (NV) protein of the m V - P R T The NV gene contained 336 bp open readmg frame and encoded a protein of 11 1 amino acids with a molecular weight of 13.2 kDa. The deduced amino acid sequence of NV of IHNVPRT was found to be 90-95% identical to those of foreign isolates of IHNV. These results indicate that NV gene of the MNV is highly conserved among &ifferent strains of THNV Northern blot analyses revealed that the levels of NV gene expression were strongly elevated after 20 h post-infection. In order to identify the role of NV in the replication of MNV in fish cells, IHNVinfected cells were treated with antisense oligonucleotides. While IHNV-PRT exposed to glycoprotein (G) antisense oligonucleotide showed severely reduced growth, the growth of virus exposed to NV antisense oligonucleotide was not affected by NV antisense oligonucleotide, which suggests that NV is not essential for replication of IHNV in fish cells.

Various conditions for mushroom were investigated to study their effects on the mycelial growth of oyster mushroom and pathogens. Our results show that the optimal pasteurization temperatures for mycelial growth and pathogens are $60^{\circ}C\;and\;121^{\circ}C$ respectively. Both were then decreased by heating over $60^{\circ}C$ and getting down temperature under $121^{\circ}C$, respectively. In the experiment for pasteurization time, it was showed that both 8 and 12 hours pasteurization were greater than 24 hours treatment for the mycelial growth. In contrast, we didn't find any particular effect by different soaking time of substrates. The pH In substrates was leveled well by pasteurization and after-fermentation even though the acidity was lowered by extending the soaking time. Our results also show that the mycelial growth is greatest at $25{\sim}30^{\circ}C$ regardless of pasteurization time for substrates, Through the experiment with paddy straw as a substrate, it was showed that two time pasteurization was greater than one time for mycelium growth and pro-fermentation of paddy straw before pasteurization have resulted in worth mycelial growth compared with that of normal condition.

The oxidizer shutoff valve of a gas generator controls the mass flow rate of the propellant of a rocket engine using pilot pressure and spring the force of the valve. The developing oxidizer shutoff valve can be shut off if the pilot pressure is removed from the actuator. Therefore, force balancing is necessary to analyze the characteristics of the forces with respect to the opening and closing of the valve in order to evaluate its performance. In light of this, the valve has been designed to adjust the control pressure required to open the poppet and to determine the working fluid pressure at which the valve starts to close. Under cryogenic flow test as a tests level of C.R.T(Control Random Test), the chattering phenomena occurred due to much leakage of a metal seat section. The pressure for chattering of the oxidizer valve is predicted at about 11 bar using force balancing analysis.
