Method: Participants for this study were 1 man and 9 women caregivers. Data was collected through in-depth interviews from October, 2005 to April, 2006 and analyzed using Strauss and Corbin's grounded theory methodology. Results: "Finding a way to live together" emerged as a core category and it reflected expanding consciousness allowing them to see each other in a more positive view. The basic social process of "finding a way to live together" includes 3 phases: 1) recognizing the problems, 2) finding solutions to the problems, and 3) accepting the changes in their surrounding. Lack of privacy, family troubles, extreme distress, and unavailable caregivers are reflected in the process of recognizing the problems. The process of finding solutions was making a decision, obtaining family agreement, choosing the best nursing home, and enduring the financial burden. Possible outcomes of the last phase include recovering peace of mind and continuing conflict. Conclusion: Findings from this study offer suggestions for developing a strategy to help not only the elderly but also the family caregivers.

Methods: Nineteen mothers who defected from North Korean were recruited in Hanawon and data were collected through face-to-face interviews. Grounded theory methodology developed by Strauss and Corbin (1998) was adapted for theoretical sampling and analysis. Interviews were recorded with consent and transcribed verbatim. Results: The core category was discovered to be 'pursuing positive parenting'. Phenomenon was identified as 'acting out of frustration' and this series of processes was categorized as having four stages: 'harsh reality', 'moving forward', seeking transition', and 'internalization'. Conclusion: The results indicate that their parenting experiences were in a transition process and, thus, it is critical to develop positive parenting intervention programs as a way to promote the empowerment of these mothers in parenting to help them support themselves and their children.

  • The purpose of this study was to explore bringing-up process of mothers with first baby in the context of Korean culture. The field survey was performed with four primiparae during four months from September, 2000 and grounded theory approach was used for data analysis. The results indicated that there were 27 primary categories and 12 secondary categories. Unclearness was extracted as an expression of the core category of bringing-up process. The subjects was faced with care of their baby after delivery and experienced formation and deepening of unclearness. After that, they also went through expression and disentanglement of complication caused by unclearness. It is found that the core concept of this study, the unclereness("Magmagham" in Korean) means a confusion, a burden, a helplessness and a hardness. New mothers make an effort to resolve this situation with strong motherhood in their mind. By supports from significant others, they are empowered and some mothers get depressive feelings. The findings of this study are contributed for nurses to understand new mothers in developmental crisis. We suggested that the nursing intervention strategies including learning baby care skills and preparing emotionally a motherhood must be given new mother during pregnancy period.

  • Cerebral atrophy affects the brain and is a common feature of patients with mild cognitive impairment or Alzheimer's diseases. It is evaluated by the radiologist or reader based on patient's history, age and the space between the brain and the skull as indicated by magnetic resonance (MR) images. A total of 70 patients were scanned in the supine and prone positions before three radiologist assessed their atrophy level. This study examined the radiologist's assessment of the cerebral atrophy level using a graded response model of item response theory (IRT). A graded response model (GRM) is fitted to our data and then item-fit and person-fit statistics are evaluated to assess the fitted model. Our analysis found that the cerebral atrophy level is better discriminated by readers in the prone position because all item slopes were greater than 2 at this position, versus the supine position where all the slope parameters were less than 1. However, the thresholds are very similar for the first reader and are quite different for the second and third readers because the scanning position affects readers differently as the category threshold estimates vary considerably between the readers..

  • 본 논문은 데이비드 린치 감독의 첫 작품 <이레이저 헤드>에 나타난 추(醜)의 미에 관한 연구를 목적으로 한다. 먼저 배경 연구로, 미의 역사에서 '추'가 등장한 역사를 고찰하고, 미학적인 관점에서 '추'가 어떤 의미를 지니는지 논의한다. 이어서 '추'에 관하여 심도 있는 논의를 전개한 미학자 로젠크란츠의 '추'의 미학 이론을 살펴보고, 이와 유사하거나 다른 측면의 의견들에 대해서도 짚어볼 것이다. 끝으로 현대 영화에서 추의 미가 적용되는 미적 양상을 논증하기 위해 데이비드 린치의 영화 '이레이저 헤드'의 특정 사운드를 구체적으로 분석하고 이미지와의 관계를 고찰한다. 본고는 이상의 논의를 통하여 영화라는 분야에서 미적 범주로서 '추'가 지니는 미학적 의미를 새롭게 조명하고자 한다.

  • The study aims to investigate the antecedents affecting purchase intention in the category of green skincare products. Many studies have used the theory of planned behavior to investigate factors affecting intention to purchase products in general. This paper not only retests the influences of attitude, subjective norm, perceived behavioral control on the intention to buy eco-friendly skincare products but also suggests a new antecedent - environment knowledge of purchase intention. More importantly, this study is the first to propose the moderating effect of country of origin and product knowledge on the relationship between attitude and purchase intention. This study employs a sample of 350 female customers from 18 to 39 years old in Ho Chi Minh City. The research applies the Multiple Linear Regression to analyze the proposed hypotheses in the conceptual framework and results in significant outcomes. The result shows that attitude is the most influential factor then, subjective norm, perceived behavioral control and environmental knowledge. Most importantly, the findings of this study suggest that product knowledge is found to moderate the effect of attitude on purchase intention. The finding of moderating effect is a new contribution to the literature and future research can be carried out to validate this result.
