$LiMn_2O_4$ powders were prepared by burning and subsequent calcination of PEG-metal nitrate precursor. After the burning stage of the precursor, some minor phases such as $Mn_2O_3$ (or $Mn_3O_4$), MnO, and carbonate were formed and single phases of $LiMn_2O_4$ were obtained by further calcinations above 400 ℃. From thermal analysis of the precursor, a violent thermal decomposition, which was indicated by a drastic weight loss accompanied by a sharp and strong exothermic peak, was observed and probably caused by an oxidation-reduction reaction between oxidizer and fuel. The formation of the minor phases could be explained in terms of the burning behavior of the precursor by employing valence concepts of propellant chemistry. The calcined powders were composed of submicron-sized but highly agglomerated particles and showed very broad particle size distribution.

The purpose of this study was to find out whether home environmental variables had a greater effect on adolescents' violence against parents. The results of self-reporting questionnaires are as follows ; The victims of violence are mainly mothers. The socio-economic status didn't influence on the degree of violence against parents. The adolescents of the extreme family type used more serious violent behavior. The higher the degree of observed and experienced violence is, the higher the degree of violence against parents. Also, the higher the degree of home education is, the lower the degree of violence against parents. Of all variables, the observed violence and structure-environmental variables account for 37.6% of adolescents' violence against parents. The results of in-depth interview showed that birth-order didn't affect violence against parents. The victims of violence were mainly stepmothers and stepfathers. These parents' educational attitudes were disagreement in parents, seriously inflicted corporal punishment and were indifferent to adolescent. Also, interviewed adolescents were observed and experienced violence in home and used violence against others.

The 21th century is the time-area where knowledge, information and culture are considered as the pivotal factor for keeping society. Thus, this affects every part which consists of culture. By 2000, various cultural changes create several culture trends all over the world. Above all, advent of CHAV is the remarkable cultural phenomenon because of its life style, fashion and self-awareness. This study analyzes CHAV's life style and fashion based on regarding it as subordinate culture. In terms of these aspects, CHAV's fashion can be divided into three parts by its inner and outer traits. The first is merrymaking style which is composed of combination, parody and excessive decoration of different factors. This is a kind of Pop-Art style that imitates mass consuming culture. The second is ostentation style which emphasizes CHAV's traits and acts group behavior. The third is violence style. CHAV tries to appear violent and indifferent for gaining their rights and power. As a result, CHAV is the rebounding phenomenon that means psychological fear and conflict which neglected people have to resist official authority.

Background : Patients with command hallucinations are commonly assumed to be at high risk for dangerous behavior. However the issue of whether command hallucinations hold any clinical relevance in schizophrenic patients has not been established. Method : The author analyzed the clinical and research records of schizophrenic patients with auditory hallucinations who participated in outpatient research follow-up for 9 months after discharge. Patients with auditory hallucinations were classified as experiencing or not experiencing command hallucinations based on clinical psychiatric assessment. Results : Of 63 patients with auditory hallucinations, 29(46%) reported the command hallucinations and these hallucinations often were violent in content(44.8%). Patients with command hallucinations were not significantly different from patients without command hallucinations on sociodemographic and clinical characteristics, and clinical or prognostic course variables, but patients with command hallucinations had significantly more short hospitalizations(less than one month) than patients without command hallucinations. 3 of the patients with command hallucinations who committed suicide during the follow up periods were died. Conclusion : Command hallucinations may be frequent, and in most cases they have minimal influence on the outcome of schizophrenia, but if the patients with command hallucinations have a history of suicide attempts before admission, the possibility of suicide attempts by command hallucinations should be considered.

Purpose: This is a qualitative descriptive study with the purpose of identifyng the health problems and related factors of socially vulnerable school-age children in Seoul, South Korea. Methods: Two focus group interviews and two individual interviews were conducted with eleven participants. They were two class teachers, three school nurses and two daycare teachers working at elementary schools and three social workers and a welfare worker working at community childcare centers. Data were analyzed using qualitative content analysis. Results: The identified psychosocial problems were 'distracting and excessive behavior', 'depression and helplessness,' 'aggression and violent behaviors', and 'internet overdependence'. The revealed physical health problems were 'poor hygiene', 'obesity', and 'gastrointestinal problems'. In addition, the fact that physical and psychosocial problems are closely inter-linked was reaffirmed through practical examples. Meanwhile, socioeconomic, family environmental, social experiential and individual factors were found to affect children's health. Relationships within a family or a peer group and healthy lifestyle were considered critical issues to deal with in order to improve the childrens' health status. Conclusion: It was proved that socially vulnerable school-age children have various physical and mental health problems due to multiple factors. Therefore, it is required to design nursing approaches that help them achieve optimal health status.
