Purpose: The purpose of this study was a comprehensive understanding about maternal transition in mothers with high risk newborns according to the degree of situational meaning. Method: A methodological triangulation that combines qualitative and quantitative methods was used. The situational meaning of a high risk newborn mother was identified using a Family Meaning Attribution Scale. According to the degree of situational meaning, in-depth interviews were conducted at 3 time periods postpartum: between 3-10 days after childbirth, around the time of the newborn's discharge, and between 10-12 weeks after childbirth. Quantitative data was analyzed using descriptive statistics and t-test. Qualitative data was analyzed using Tutty, Rothery, & Grinnell's methodology. Result: The average score of the situational meaning in high the risk newborn mother was 53.57(possible score is between 0-96) and the average score of each item was 1.67. A Maternal transition process in the mother that has a positive situational meaning was conceptualized in three distinctive phases: confusion, accepting, and shaping phases. The Maternal transition process in the mother that has a negative situational meaning was also conceptualized in three distinctive phases: avoiding, conflicting, and accepting phases. Conclusion: It is necessary that the nurses provide high risk newborn mothers with individualized care considering both the situational meaning that is attributed to them and the maternal transition phase that they are faced with.

Purpose: While there are a number of studies on children with disabilities, there have been few studies on mothers of children with autism. The purpose of this study was to explore the process of life transition of mothers who have children with autism. Methods: From June 2007 to May 2009, the researcher interviewed 15 mothers of children with autism living in Seoul City, Gyeonggi or Chonbuk Provinces, and then analyzed the data gathered using the constant comparative method of grounded theory. Results: "Living together holding a string of fate" was a core category showing along the continuum of life. The basic social process of life transition encompassed 5 stages: stages of denying, wandering, devoting, mind controlling, and finally accepting. These five stages proceeded in phases, though returned back to the wandering stage occasionally. Conclusion: This study has opened the door to understanding how mothers of children with autism experienced life transition. The findings suggest that differentiated support and care at each stage should be given and there is the need to develop transition assessment tools for mothers of children with autism.

Purpose: This study was conducted to identify predictors of the stage of change for smoking cessation of male university students on the basis of the Transtheoretical model (TTM). Methods: The 388 current smokers or exsmokers who agreed to participate were recruited from three areas in Korea from August 2 to September 5, 2006. Data was analyzed using a SPSS program for descriptive statistics, ANOVA, and multiple logistic regression. Results: Most subjects (76.8%) were current smokers. According to stages of change, there were statistically significant differences in self efficacy, smoking temptation, decisional balance (cons, pros), and processes of change. The predictors of transition from contemplation to preparation were behavioral and experiential processes. The predictors of transition from preparation to action were pros of smoking and experiential process. The predictors of transition from action to maintenance were cons of smoking and behavioral process. Conclusion: Specific nursing interventions based on stages of change need to be developed for smoking cessation of male university students.

Technology transition from defense technology to weapon system is an important process for defense acquisition program. Many countries such as USA, UK, Australia and Republic of Korea use technology readiness level (TRL) as a tool for technology transition by identifying critical technology elements (CTEs) and assessing the technology maturity. In this paper we review a transition process for the defense acquisition. Then we suggest a method to evaluate system's TRL using each component TRL and integration readiness level (IRL) between each technologies. We apply the method to an ACTD project. A result show that technology maturity is influenced by integration between technologies.

Sliding experiments have been conducted on alumina and silicon carbide ceramics. Wear and friction data of both materials indicate that wear proceeds in two distinct stages. The wear occurs by a relatively mild plastic-grooving process in the initial stage, but eventually gives way to a severe grain pull-out process after a defined period of sliding test. The datails of the transition mechanism are presented. The effects of grain size and second phase particle on the wear transition are also presented.

This research, as a study of the documentary records, examined the process of men\`s wear development year by year, looking into the newspapers which show objectively social phenomena in those days. The outcomes therefrom were classified according to the important factors of dress and ornaments\` modeling i. e. style, color, pattern, material, ornamentation method. And then, the process of men\`s wear transition was analyzed based on the aforesaid examination with its classification. The above analyses revealed that a transition of a dress and ornaments closely correlates with a social and cultural change and also meant that the dress and ornaments symbolizes the social phenomena in those days. Thanks to the holding of Seoul Olympic Games in 1988, Korean society had tremendously grown with rapid changes in its politics, economy and culture. Also, men\`s wear type became innovative, breaking from the existing orthodox one due to the transition of men\`s viewpoints on value and their lives\` style.

The Purpose of this paper contribute to design the multistate Markov process for the reliability of a system when the transition-rates of each unit depend on the current state of the system. The system transition-rate matrix has the form of the kronecker sum of transition rate matrices for the units, is analyzed and investigated. As a result, the system which has the state-dependent units is detaily analyzed and introduced by the approach of an algorithm for the system transition-rate matrix based on the kronecker algebra.

Lattice process models are used to explain phase transitions in statistical mechanics, a branch of physics. The Ising model, a specific form of lattice process model, was proposed by Ising in 1925. Since then, variants of the Ising model such as the Potts model and the unitary cell model have been proposed. Like the Ising model, it is believed that the more general models exhibit phase transitions on the critical surface, which is based on the mathematical equation. In statistical sense, phase transitions can be simulated through Markov Chain Monte Carlo (MCMC). We applied Swendsen-Wang algorithm, a block Gibbs algorithm, to a general lattice process models and we simulate phase transition phenomena of the unitary cell model.

The relationship between elongation of hypocotyl and its vascular transition was studied with seedling of Glycine max. the hypocotyl elongation proceeded acropetally from the base of hypocotyl toward the cotyledonary node. The vascular transition did not occur in the basal region of the hypocotyl, which did not nearly elongate, with exarch radial vascular bundles. However, the vascular transition was almost completed at the middle part of the hypocoty, more or less elongated, with endarch collateral vascular bundles. Such bundles also appeared in the uppermost region of the hypocotyl, in which the elongation was the most striking. These results suggested that the vascular transition was related to the hypocotyl elongation and that the transition of primary vascular system in Glycine max seedling was established by rather rapid process. Our observations of the serial sections from root to hypocotyl revealed that the vascular system through the root-hypocotyl-cotyledon was a unit, to which one of the epicotyl that did not participate in transition was superimposed.

Purpose: The purpose of this research was to develop a scale to measure the life transition process of parents of children with autism, against the backdrop of a lack of research on this topic. Methods: Seventy preliminary items were drawn from previous qualitative research, and content validity was tested by three professors as well as three parents of children with autism. A questionnaire survey was also done between August 2011 and February 2012. Data were collected from 207 parents of children with autism and analyzed using descriptive statistics, item analysis, Cronbach's alpha, Pearson correlation coefficients, and factor analysis with the SPSS Win 15.0 program. Results: Twenty-nine items were selected to constitute the appropriate measuring scale and categorized into 5 factors explaining 63.2% of the total variance. The 5 factors were named; stages of denial (5 items), wandering (6 items), devotion (7 items), frustration (3 items), and finally acceptance (8 items). Cronbach's alpha for the 29 items was .80. Conclusion: The results of this study not only suggest assessment criteria for the life transition process of parents who have children with autism but also provide basic directions for program development to provide differentiated support and care at each stage.
