Purpose: The purpose of this study was the development of a comprehensive nursing intervention program for the client with acute lymph stasis and stage I lymphedema. Method: The Quasi-experimental design using a non-equivalent control group was used. The subjects were 22 stroke patients with lymph stasis in the control group and 23 patients in the experimental group. The complex physical therapy of Casley-Smith was carried out to the control group for 10 hours, and comprehensive nursing intervention for the experimental group was carried out for 60 minutes. The data for this study was gathered from Feb. 2002 until June 2002 and pertains knowledge about lymphedema, self-care for managing lymphedema, and circumferences of affected limbs. Data was analyzed by mean, standard deviation, ${\chi}^2-test$, and t-test. Result: The changes in knowledge about lymphedema, self-care practices, and circumference of affected limbs after nursing intervention did not show significant differences between control group and experiment group. Conclusion: It can be concluded that comprehensive nursing intervention had more efficiency than complex physical therapy in the treatment of edema for stroke patients because of it's simplicity and time saving. Thereby, the comprehensive nursing intervention program developed in this study would be a useful therapy for the clients with lymph stasis and early stage lymphedema.

Understanding the process of carcinogenesis will involve both the accumulation of many scientific facts derived from molecular, biochemical, cellular, physiological, whole animal experiments and epidemiological studies, as well as from conceptual understanding as to how to order and integrate those facts. From decades of cancer research, a number of the "hallmarks of cancer" have been identified, as well as their attendant concepts, including oncogenes, tumor suppressor genes, cell cycle biochemistry, hypotheses of metastasis, angiogenesis, etc. While all these "hallmarks" are well known, two important concepts, with their associated scientific observations, have been generally ignored by many in the cancer research field. The objective of the short review is to highlight the concept of the role of human adult pluri-potent stem cells as "target cells" for the carcinogenic process and the concept of the role of gap junctional intercellular communication in the multi-stage, multi-mechanism process of carcinogenesis. With these two concepts, an attempt has been made to integrate the other well-known concepts, such as the multi-stage, multi-mechanisn or the "initiation/promotion/progression" hypothesis; the stem cell theory of carcinogenesis; the oncogene/tumor suppression theory and the mutation/epigenetic theories of carcinogenesis. This new "integrative" theory tries to explain the well-known "hallmarks" of cancers, including the observation that cancer cells lack either heterologous or homologous gap junctional intercellular communication whereas normal human adult stem cells do not have expressed or functional gap junctional intercellular communication. On the other hand, their normal differentiated, non-stem cell derivatives do express connexins and express gap junctional intercellular communication during their differentiation. Examination of the roles of chemical tumor promoters, oncogenes, connexin knock-out mice and roles of genetically-engineered tumor and normal cells with connexin and anti-sense connexin genes, respectively, seems to provide evidence which is consistent with the roles of both stem cells and gap junctional communication playing a major role in carcinogenesis. The integrative hypothesis provides new strategies for chemoprevention and chemotherapy which focuses on modulating connexin gene expression or gap junctional intercellular communication in the premalignant and malignant cells, respectively.

Obstructive sleep apnea (OSA) is the most common type of sleep apnea and is caused by obstruction of the upper airway. Since it is closely related to sleep parameter and body indices, the study was focused on the relationship with them. The results of polysomnography (PSG) in obstructive sleep apnea was done at ENT department of Ewha women university Mokdong hospital from March to September 2010 with 52 subjects (male 35, female 17). The leads were placed to measure electroencephalogram (EEG), electrooculogram (EOG), mandibular and anterior tibialis electromyogram (EMG), airflow in nasal and oral cavity, chest and abdominal breathing pattern, snoring sound and arterial oxygen saturation ($SpO_2$) level. From sleep parameter and body indices of adult obstructive sleep apnea compared to normal adult revealed that age (p<0.01) and snoring sound (p<0.05) were increased, stage 1 sleep (p<0.01) was increased, the deeper stages (3&4) of sleep (p<0.05) were reduced. Respiratory disturbance index (RDI) (p<0.01), mean $SpO_2$ (p<0.05) and lowest $SpO_2$ (p<0.01) were also decreased. The correlation analysis from sleep parameter and body indices of OSA showed the positive correlation with age (r=0.463, p<0.001), snoring sound (r=0.278, p<0.05), stage 1 sleep (r=0.391, p<0.01) and RDI (r=0.409, p<0.01), but showed the negative correlation with the deeper stages (3&4) of sleep (r=-0.307, p<0.05), mean $SpO_2$=(r=-0.274, p<0.05) and lowest $SpO_2$ (r=-0.392, p<0.01). This study proves that obstructive sleep apnea and indices have closed related.

Purpose: This study was designed to identify the incidence risk of cardicerebrovascular disease (CVD) among male bus drivers, and to examine and compare the predictors of their health behavior according to the level of CVD incidence risk. Methods: The convenience sample of 222 male bus drivers were recruited from a bus company located in Jeonnam province. Data were collected from self-reported questionnaires and annual medical examination records from 2010. The CVD incidence risk was calculated based on the risk criteria for industrial workers. Results: The 26.6% and 26.1% of the participants were in the moderate and high risk group, respectively. The 72% of the participants were in the precontemplation stage and reported no intention to change their unhealthy lifestyles. Stepwise multiple regression analyses showed that current smoking, excessive alcohol drinking, physical inactivity and lack of knowledge were negative predictors of good health behavior in the normal/low risk group (Adj $R^2$=.443). Heavy alcohol drinking, current smoking, physical inactivity and dyslipidemia were reported by the moderate/high risk group (Adj $R^2$=.427). Conclusion: This study suggested that targeted education and counseling are needed to modify unhealthy lifestyles such as alcohol consumption, smoking and exercise among middle aged male drivers. Especially, dyslipidemia should be managed among those who are at risk for CVD.

Purpose: The purpose of this study was to examine factors related to different stages of mammography screening based on the transtheoretical model (TTM) and health belief model (HBM). Method: 143 women were recruited from community centers in W city. The mean age was 44.08 (SD=7.78) and 74 (51.7%) had experienced education on preventative behavior related to breast cancer. The Decisional Balance Scale (Pros and Cons of mammography) and Stages of Adoption of Mammography Scale by Rakowski et al. (1992) and the revised Health Belief Model Scale (Perceived Seriousness, Perceived Susceptibility and Health Motivation) by Champion (1993) were used. Result: According to the stage of adoption of mammography, 17.4% of the women were In pre-contemplation, 45.5% in contemplation, 24.5% in action, and 12.6% in maintenance. The mean differences for pros, and the decisional balances between the stages of mammography adoption were significant (F=8.84, p=.000; F=7.20, p=.000). Education related to prevention of breast cancer was the most important variable. Prevention education, history of breast disease and pros of mammography explained the stages of mammography adoption ($R^{2}=26%$). Conclusion: Findings support TTM as a useful tool for improving mammography adherence. Behavioral interventions that target decisional balance and health belief can effectively promote adherence to mammography.

This study was conducted to investigate the effects of quiescent treatment of donor cells and activation treatment time of recipient cytoplasm on nuclear remodeling and in vitro development of somatic cell-cloned bovine embryos. Serum starved, confluent and nonquiescent cycling adult skin cells were teansferred into enucleated oocytes. Nuclear transfer oocytes were activated at 30 min, 1 and 2 hrs after electrofusion. Some nuclear transfer embryos(23% to 35%) extruded a polar body, which was not affected by quiescent treatment of donor cells and activiation time of recipient cytoplasm. About 68% of nuclear transfer embryos fused with a serum starved cells has a chromatin clump, but which was not different from embryos fused with confluent(51%) and nonquiescent(47%) cells. The proportion of embryos with a single chromatin clump was sightly increased when nuclear transfer embryos were activated within 30 min after fusion(69%) compared to those were activated at 1 and 2 hrs after fusion, but there was not significantly different. Development rates to the blastocyst stage were 8.6% and 15.9% when serum starved and confluent cells were transferred, which were higher than that of control group. Developmental rate to the blastocyst stage was higher in embryos were activated within 30 min after fusion (17.3%) compared to those of embryos were activated at 1 and 2 hrs after fusion (P<0.05). From the present result, it is suggested that quiescent treatment of donor cells and activation time of recipient cytoplasm can affect the in vitro development. Quiescent plasm activation within 30 min after fusion could increase the number of embryos with a normal chromation structure, which results in increased in vitro development.

To breed powdery mildew resistant varieties, 104 accessions of Cucurbita spp. germplasm were evaluated. Powdery mildew resistance and horticultural characteristics of the accessions were investigated in the field conditions. C. martinezii was selected for high resistance to powdery mildew in the field. The growth of powdery mildew pathogen and response of leaf surface tissue to the pathogen were observed after artificial inoculation to resistant C martinezii and susceptible C. moschata cv. 'Wonye No.402'. Mycelium growth was very clearly different between resistant C. martinezii and susceptible C moschata cv. 'Wonye No. 402' at 5 days after inoculation at the adult stage. Interspecific hybridization was attempted to transfer powdery mildew resistance gene(s) from C. martinezii to C. moschata. A single dominant gene action was postulated as deter mining powdery mildew resistance at the seedling stage. But for the effective selection of powdery mildew resistant individuals, it was established that adult plant resistance should be confirmed in the field conditions after the seedling test. Through the seedling and field tests, C. moschata lines resistant to powdery mildew and superior to horticultural characteristics, were selected after 2 backcrossing and 3 selfing generations. The fruit characteristics of newly developed lines were similar to those of the recurrent parent, 'Jaechenjarae'.
