The purpose of this study is to provide a basis for nursing intervention strategies to promote quality of life in cancer patients. Therefore the study is designed to evaluate the effectiveness of perceived health status, self-esteem, health locus of control, self-efficacy, perceived susceptibility /severity, health promoting behaviors, and hope for quality of life. The sample was composed of 164 stomach cancer patients who visited outpatient clinics at a university hospital in Seoul. The following instruments were used in the study after some adaptation : Lawstone and others' Health Self-rating Scale, Rosenberg's Self-esteem Scale, Wallston and others 'Multidimensional Health Locus of Control Scale, Sherer & Maddux's Self-efficacy Scale, Moon's Health Beliefs Scale, Walker and others' Health Promoting Lifestyle Profile, Nowotney's Hope scale and Noh's Quality of Life Scale. Data were analyzed using a SAS program for Pearson correlation coefficients, descriptive correlational statistics and stepwise multiple regression. The results are as follows : 1. The scores on the quality of life scale ranged from 115 to 243 with a mean of 177.84(SD : 25.35). The mean scores(range 1-5) on the different dimensions were : emotional state 3.37 : economic life 3.47 : physical state & function 3.52 : self-esteem 3.66 : relationship with neighbors 3.37 ; family relationships 3.80. 2. There was a significant correlation between all the predictive variables and the quality of life (r=.20-.65, p<.01). 3. Stepwise multiple regression analysis showed that : 1) Self-esteem was the main predictor of quality of life and accounted for 46.9% of the variance in quality of life. 2) Perceived health status, hope and perceived susceptibility/severity accounted for 11.8%, 8.3%, 1.5% of the variance in quality of life, respectively. 3) Self-esteem, perceived health status, hope & perceived susceptibility /severity combined accounted for 68.5% of the variance in quality of life. In conclusion, self-esteem, perceived health status, hope and perceived susceptibility / severity were identified as important variables in the quality of life of cancer patients.

The on-line measurement of high-power IGBT collector current is important for the hierarchical control and short-circuit and overcurrent protection of its driver and the sensorless control of the converter. The conventional on-line measurement methods for IGBT collector current are not suitable for engineering measurement due to their large-size, high-cost, low-efficiency sensors, current transformers or dividers, etc. Based on the gate driver, this paper has proposed a current measuring circuit for IGBT collector current. The circuit is used to conduct non-intervention on-line measurement of IGBT collector current by detecting the voltage drop of the IGBT power emitter and the auxiliary emitter terminals. A theoretical analysis verifies the feasibility of this circuit. The circuit adopts an operational amplifier for impedance isolation to prevent the measuring circuit from affecting the dynamic performance of the IGBT. Due to using the scheme for integration first and amplification afterwards, the difficult problem of achieving high accuracy in the transient-state and on-state measurement of the voltage between the terminals of IGBT power emitter and the auxiliary emitter (u_Ee) has been solved. This is impossible for a conventional detector. On this basis, the adoption of a two-stage operational amplifier can better meet the requirements of high bandwidth measurement under the conditions of a small signal with a large gain. Finally, various experiments have been carried out under the conditions of several typical loads (resistance-inductance load, resistance load and inductance load), different IGBT junction temperatures, soft short-circuits and hard short-circuits for the on-line measurement of IGBT collector current. This is aided by the capacitor voltage which is the integration result of the voltage uEe. The results show that the proposed method of measuring IGBT collector current is feasible and effective.

People have experienced physical problems including vision problems with aging; some are normal and some are abnormal. When they have abnormal and impaired vision, they have a lower level of life satisfaction than their sighted peers. For the elderly with sight loss, well-designed housing could be an important indicator for their quality of life. Housing adjustment and modification could help the elderly cope with sight loss, do daily activities more independently, and lead to better quality of life. The purpose of this study is to investigate housing conditions for the elderly with vision impaired, state of housing adjustment or modifications, and the effects of housing conditions on the wellness of the elderly in Korea. For this study, 18 housing cases were investigated and a total number of 65 visually impaired people aged over 55 participated. Housing condition of those participated was poor. Most observed home hazards are level differences in living areas, obstacles in the hallway, confined space that is not allowed structural modification, swing doors from wardrobe or cabinets, color contrast, poor lightings, and etc. Majority of households participated in this study did not make modification or refurbishments, rather many of them tend to adapt themselves to their residential environments. Older adults living in better housing condition and under less difficult environments are likely to have higher life satisfaction. The effects of housing condition on wellness could be more influential when individual capabilities (e.g. health condition) are weaker. The findings underline that with intervention of individual characteristics, the effects of housing and physical environment on negative outcomes of vision loss would get ameliorated or reduced.

Purpose: The purpose of this study was to compare the feeling state guided imagery(FSGI) and end state guided imagery(ESGI) on stress and performance of an intramuscular injection of nursing students. Method: The design was a time series with a nonequivalent control group pretest-posttest study. Data was collected from the 23 rd to the 25th of Nov. 2004. The subjects of this study were 40 female sophomores (21 for the ESGI, 19 for the FSGI). The instruments used in this study were the Visual Analogue Scale for Stress and the Nursing Skill Performance Check-list on Intramuscular Injection developed by the researchers(10 items). Guided imagery was provided through audiotapes for 8 minutes. A pretest was given before applying the guided imagery, posttest 1 was performed after the intervention, posttest 2 was performed before the intramuscular injection and then evaluation of the performance of the intramuscular injection was done. Data was analyzed using t-test, and Repeated Measures ANOVA. Result: The level of stress for those who received the ESGI and FEGI was not significant and the level of the nursing skill performance for those who received the ESGI was significantly higher than that of students who received the FEGI. Conclusion: The use of ESGI has an effect on learning psychomotor nursing skills and further research is needed on stress.

The purpose of this study is to find out the effects of personal characteristics, social support, depression, and metamemory on the older adults' memory performances. The subjects of the study consisted of 95 older adults over the age of 60 who are living in Busan. Some data were collected by means of the interview method, using questionnaires for metamemory (MIA questionnaire by Dixon, et al., 1988), and depression(GDS by Yesavage and Sheikl, 1986), social resoueces(Duke university, 1978), family support(Hyun-Sook Kang, 1985). The other data were collected by the testing method on the memory performance such as the immeadiate word recall task, the delayed word recall task, the word recognition task(Elderly Verbal Learning Test by Kyung Mi Choi, 1998), and the face recognition task(Face Recognition Task tool developed by Hye-Sook Min). The results of this study were as follows; 1. The level of metamemory is 3.4 points in the 5 point scale, the grades of the task and the achievement are relatively high and the grades of the change, the control, and the anxiety are relatively low in the sub-concepts. 2. Metamemory have significant relation with age(r=-.44), educational attainment(r=.46), depression(r=-.58), family support(r=.20), social resources(r=.20). 3. The significant variables to predict older adults' metamemory are educational attainment(22%), sex(11%), age (8.3%), depression(4.7%), and illness state(3%). 4. The strong variables to predict memory performances are metamemory, age, depression, social resources, educational attainment, illness state, and limitation of daily living activity related to illness. In conclusion, the enhancement strategies of metamemory and the social support and the prevention or reduction of depression are necessary to increase older adults' memory performances. Ultimately in this respect nurses' roles are very important in developing and performing some intervention programs for old adults' memory improvement, which have significant meanings in the field of nursing science.

Bullet embolism is a potential complication of a gunshot wound, especially with a low-velocity missile. This is because the trajectory of the low-velocity bullet can be significantly slowed as it passes through tissue. An unusual form of travel can occur in which the bullet enters the vasculature but does not have enough kinetic energy to create a through-and-through wound, leading it to remain inside the vasculature. Once inside the vasculature, the bullet could migrate to different parts of the body, potentially causing complications such as ischemia, becoming a source of thromboembolism, or functioning as a nidus for infection. The management of a bullet embolism varies from case to case, as each patient with this issue has a unique body habitus that can result in infinite possibilities of the trajectory and destination of the bullet embolus. Additional damage to surrounding vasculature or tissue can occur, as well as embolization of the bullet to critical areas of the body. Here we present the case of a 72-year-old man who had a self-inflicted gunshot wound to the chest with a low-velocity bullet, which penetrated the right atrium of the heart. It traveled into the venous vasculature through the right atrium, into the inferior vena cava, and eventually settled in the right internal iliac vein. He refused further intervention and management after initial workup and resuscitation.

Objectives : This study aimed to investigate the prevalence and risk factors of depression within two weeks after stroke. Methods : A total of 362 stroke patients were recruited. Depression (major and minor depressive disorders) was diagnosed by applying DSM-IV criteria. Data on socio-demographic characteristics (age, gender, education, marital state, living state, religion, occupation, income, life event, and social support), stroke severity (NIHSS), disability (BI), stroke hemisphere and location, vascular risk and disease, and previous history of stroke and depression were obtained. Results : Depression was present in 90 (24.9%) patients: major depression 29 (8%) and minor depression 61 (16.9%) patients. In the univariate analyses, depression was associated with older age, higher number of stressful life event, poorer social support, severe disability, anterior stroke location, previous history of stroke and depression. In the multivariate analyses, depression was independently associated with higher number of stressful life events and poorer social support. Conclusion : Depression was common and was determined by premorbid levels of stress and social support in stroke patients at acute stage. More intensive psychiatric care and intervention is needed for the high risk group.

The researcher would like to suggest that the delivery experience varies depending on the personal situation and the childbirth experiences of the mother. The goals of this study are : 1. To find out the subjectivity structure on delivery experience. 2. To describe the differences in delivery experience depending on the delivery methods. 3. To suggest effective nursing intervention for each type. Q-methodology was used for the research design. One of the main reasons to use this Q methodology. Because each individual's delivery experience can be different. The result of this study shows that the subjectivity related to the delivery experience of mother has at least four distinctive types. Type I mothers can be named as "Motherhood Identity Recognition Type". Type I subjects accept delivery experience very positively, show interest in the health of the baby, and identify their motherliness with responsibility. Type II mothers can be named "Leaping to Maturity Type". It can be explained as a state that mothers experience pain, but by understanding and enduring the pain, the pain is changed to maturity. Type III mothers can be named as "Pride Experience Type". Type III feels vaginal delivery as a process to become a real mothers, and have great pride in making this type of significant emotiange delivery. Therefore, they think the labor pain is worth the value and believes that there are other differences between vaginal delivery and cesarean section. Mothers of Type III take the delivery experience to be meaningful. Type IV mothers can be named as "Lack of Motherhood Transition Type". This type does not seem to feel sorry for their babies for going through a cesarean section delivery. The also do not have the satisfaction of delivery and motherliness identity is low. In addition, they especially do not feel affection towards their babies. Also, because they delivered babies in a state of anesthetics, they do not seem to feel much different, but show negative reactions toward themselves.ow negative reactions toward themselves.

Purpose - The purpose of this study is to investigate the relationships among Chinese state-owned enterprises (SOEs), previous M&A experience, and the probability of deal completion in cross-border mergers and acquisitions (CBMAs). Since Chinese SOEs tend to be recognized by host countries as agents of their home country government, this study argues that SOEs will face difficulties in completing CBMA deals. However, the study expects that these difficulties may vary depending on whether the firm has previous M&A experience because firms can gain the knowledge and capabilities necessary to implement subsequent M&As successfully from past M&A experience. Design/methodology - To investigate our argument, we conduct a logistic regression using a sample of 363 CBMA deals from 304 Chinese publicly listed firms during 2007 to 2017. We used SOEs as an independent variable, experience of domestic and foreign M&As as moderating variables, respectively, and CBMA deal completion as the dependent variable. Findings - The study shows a negative and significant relationship between Chinese SOEs and the completion likelihood of CBMA deals. We find that this negative relationship is strengthened when the firm had prior domestic M&A experience, whereas foreign M&A experience alleviated the negative relationship. Originality/value - The issue of government ownership has remained unclear since government intervention has both advantages and disadvantages in pursuing CBMAs. Our findings support literature that argues Chinese SOEs face legitimacy concerns in the host countries, thereby lowering their CBMA deal completion likelihood. Furthermore, the study enriches the literature by identifying different moderating effects of domestic and foreign M&A experience on the negative relationship between SOEs and CBMA deal completion.
