The purpose of the research was to determine the effect of home care service on the quality of life in patients with gynecological cancer. This randomized case control study was carried out in a womans hospital between September 2011 and February 2012. Women undergoing gynecological cancer treatment were separated into intervention and control groups, of 35 patients each. The intervention group was provided with nursing care service through hospital and home visits ($1^{st}$, $12^{th}$ weeks) within the framework of a specifically developed nursing care plan. The control group was monitored without any intervention through the hospital routine protocols ($1^{st}$, $12^{th}$ weeks). Data were collected using An Interview Form, Home Visit Monitoring Form and Quality of Life Scale/Cancer Survivors. Effects of home care service on the quality of life in gynecological cancer patients were investigated using chi-square tests, McNemar's test, independent t-test and ANOVA. This study found that the intervention group receiving home care service had a moderately high quality of life (average mean: $6.01{\pm}0.64$), while the control group had comparatively lower quality (average mean: $4.35{\pm}0.79$) within the 12 week post-discharge period (p<0.05). This study found home care services to be efficient in improving the quality of life in patients with gynecological cancer.

Residual wall thicknesses, corrosion rates, and residual life of thirty four samples of cast iron pipes(CIPs) and ductile cast iron pipes(DCIPs) collected from water mains of B city were studied to estimate their remaining service life or optimum time of rehabilitation. The internal maximum corrosion depths of samples measured using a dial gauge after shot blasting were twice higher than the external in most cases. Therefore corrosion of water pipes was much more affected by internal water quality than soil. Residual wall thicknesses of DCIPs were higher than those of CIPs. That reason was thought to be that DCIPs have been protected from internal corrosion by lining cement mortar. Residual life calculated by maximum corrosion rate was ranged up to 44 years with 12.40 years average. Since most CIPs were much deteriorated, rehabilitation plan should be established soon in B city. Residual life of DCIP was 33.52 years average. When cement mortar lining is used up by neutralization of DCIPs. DCIP also should be rehabilitated.

Purpose: This study aims to figure out the characteristics of corporate life cycle and resource input in terms of the sustainability diagnosis of pharmaceutical companies in Korea. Research design, data, and methodology: Using the Gompertz model under the assumption that companies have finite resources, this study tries quantitative interpretation of life cycle and resource input pattern for longevity companies with 25 years of experience among 158 pharmaceutical companies listed on Korean stock market based on maturity of revenue. Results: The study found revenue maturity through Gompertz model was statistically correlated with enterprise value. According to the life cycle analysis, more than 95% of 59 pharmaceutical companies were in the growth and maturity phase and have an average life cycle of 88 years and an average remaining life of 52 years. Regarding maturity profile of resource input, maturity of employees was generally high more than 60% and this meant there was jobless growth in Korean pharmaceutical industry. Conclusion: This study demonstrated there is a high statistical correlation between the maturity of a company's resource input and its revenue and enterprise value. It is believed that these results could be utilized as a basis for high fidelity function that predict revenue and enterprise value based on resource input information.

This study as a cross survey study was conducted to provide basic data for more practical approach to nursing the aged, by analyzing the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. This study was based on the survey data from the 90 aged, who are over sity years old and resident in Seoul. In order to measure the general characteristics and subjective audition, Cantril's Ladder Scale Tool was used. For the loneliness, UCLA Loneliness Scale Tool (translated into Korean to suit the Korean environment by Kim's). In order to measure the self-esteem, Rosenberg's Self-esteem Measurement Tool (translated into Korean by Chun) was used. No's Quality of Life Measurement Tool was used to the measure the quality of life. The Data were collected by direct interviewing on the subjects for this study from August 10, 1999 to September 15, 1999. In accordance with each purpose of this study, appropriate analyzing methods such as Descriptive Statistics, T-test, and ANOVA were used in analyzing the collected data. Pearson correlation coefficient was used to test the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. The result of this study is as follows: 1) The average of the degrees of subjective audition was 7.22, The factors that cause the result were sex, religion, the perception of health, the married state. 2) The average of the degrees of loneliness was 55.18, The factor that cause the result was the perception of health. 3) The average of the degrees of self-esteem was 28.42, The factors that cause the result were the number of family, the number of children, the perception of health. 4) The average of the degrees of quality of life was 71.87 the factors that cause the result were age, education, the number of children, the perception of health. 5) Correlation of Loneliness, self-esteem and quality of life is the perception of loneliness showed significant negative correlation with self-esteem (r=-.466, p=.0001) and quality of life (r=-.450, p=.0001). As a result of analysis above: Because of the recognition change of the aged, it seems to them that the subjective audition scale on the hearing disturbance aged is measured by only 10-point ladder scale is inappropriate. Therefore, it is necessary that the physiologic-index can confirm more exactly should be applied to them. It is very important that the social-psychological factor that has influence on the aged should be the self-perception of health. Thus, proper development of nursing intervention should be required to process in the self-perception of health on the aged.

Near infrared (NIR) reflectance spectroscopy was employed to develop moisture content prediction model of pitch pine (Pinus rigida), red pine (Pinus densiflora), Korean pine (Pinus koraiensis), yellow poplar (Liriodendron tulipifera) wood below fiber saturation point. NIR reflectance spectra of specimens ranging from 1000 nm to 2400 nm were acquired after humidifying specimens to reach several equilibrium moisture contents. To determine the optimal moisture contents prediction model, 5 mathematical preprocessing methods (moving average (smoothing point: 3), baseline, standard normal variate (SNV), mean normalization, Savitzky-Golay $2^{nd}$ derivatives (polynomial order: 3, smoothing point: 11)) were applied to reflectance spectra of each specimen as 8 combinations. After finishing mathematical preprocessings, partial least squares (PLS) regression analysis was performed to each modified spectra. Consequently, the mathematical preprocessing methods deriving optimal moisture content prediction were 1) moving average/SNV for pitch pine and red pine, 2) moving average/SNV/Savitzky-golay $2^{nd}$ derivatives for Korean pine and yellow poplar. Every model contained three principal components.

A Pregnancy is the women's normal physiological and developmental process, in which many psychological changes including sexual problems always occur. But there have been few guidelines on sexual life during pregnancy. So this study was performed to evaluate the sexual life of pregnant women, and to analyze the factors affecting satisfaction of sexual life during pregnancy. Questionnaires were given to pregnant women who visited two general hospitals for antenatal care as well as to attendants at a prenatal Lamaze class. The results were as followings : 1) The average age of the 194 pregnant women was 28.5 years ; 98.4% of them had educated more than 12 years. ; the average monthly income was about 15,000,000 won ; primigravida women were 81.4% of the total cases. 2) As the pregnancy progressed, the frequency of the sexual intercourses was decreased in 48.5% because of the anxiety on the fetal damages. The was no significant differences between frequency of sexual intercourses and the degrees of physical discomfort and spouse intimacy. Man superior position was taken in 88.1% ; the incidence of orgasms before and during pregnancy were 71.1% and 41.1%, respectively ; the incidence of painful sexual intercourse in primigravida women was decreased by pregnancy in 4.6%, and in the case of multigravida women it was increased in 2.1%. 3) The average point of sexual knowledge was 11.5 in total points of 20 ; that of sexual attitude was 29.1 in total points of 40 ; that of sexual satisfaction was 28.5 in perfects points of 40. 4) The factors which significantly related to the satisfaction of sexual life were spouse intimacy, sexual attitude, change of sexual body position during pregnancy, and the orgasms before and during pregnancy. Considering above results, nursing care and nursing intervention including sexual education and counselling programs are needed during pregnancy as well as before pregnancy.

The purpose of this study is to investigate the early life history of the Rhodeus fish, Rhodeus uyekii and R. ocellatus, in the Nakdong River to use as the preliminary data for the systematic study. The embryos used in the study were fertilized eggs (embryo) and larvae after artificial fertilization. The long diameter of the eggs of the R. uyekii was 3.39-3.97 mm (average $3.68{\pm}0.41mm$, n=30) and the short diameter was 1.36-1.55 mm (average $1.45{\pm}0.13mm$, n=30). The long diameter of the eggs of the R. ocellatus was 2.53-2.71 mm (average $2.62{\pm}0.12mm$, n=30) and the short diameter was 1.47-1.60 mm (average $1.53{\pm}0.09mm$, n=30). Hatching time was 48 hours for the R. uyekii and 50 hours for the R. ocellatus given that the average water temperature was $21.5^{\circ}C$. The hatched larvae were 4.95-5.00 mm (average $4.98{\pm}0.04mm$, n=5) for the R. uyekii and the total length was 3.66-3.69 mm (average $3.67{\pm}0.02mm$, n=5) for the R. ocellatus. R. uyekii was found to be 15.5-15.8 mm at total length (average $15.6{\pm}0.21mm$, n=5) on the 56 days after hatching with the number of dorsal fins being ⅲ-9, anal fins ⅲ-10, ventral fins ⅲ-5. The R. ocellatus was found to be 15.8-16.0 mm (average $15.9{\pm}0.14mm$, n=5) at total length on the 58 days with the number of dorsal fins being ⅲ-11, anal fins ⅲ-12 and ventral fins ⅲ-5 where the number of all fin stalks reached maximum.
