Our study was carried out to develop the severity-adjustment model for length of stay in hospital for percutaneous coronary interventions so that we would analysis the factors on the variation in length of stay(LOS). The subjects were 1,011 percutaneous coronary interventions inpatients of the Korean National Hospital Discharge In-depth Injury Survey 2004-2006 data. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for percutaneous coronary interventions. There was variation of LOS in regional differences, size of sickbed and insurance type. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

The purpose of the phenomenological study was to explore the meaning of family adjustment process experience according to married immigrant women's perception and to enrich our understanding. In order to accomplish the purpose of research, six married immigrant women participated. Data were collected through in-depth interview. In addition, the data were analyzed by a Colaizzi's phenomenological analysis. The findings showed that the meaning of family adjustment process experience in married immigrant women were identified as 37 themes and 8categories. The 8 categories consisted of "deciding to marry a foreigner", "first meeting and marriage", "starting to living as a korean", "getting along with husband", "becoming a family with in-laws", "playing one's role as a mother", "missing hometown and family", "adjusting to living in Korea". Based on the findings, we discussed the meaning of family adjustment process experience in married immigrant women. And lastly, this results made suggestions for the social welfare policies and practices for them and their families.

Differences in physicochemical characteristics of sediment and changes in density, height and dry matter of shoots along different water depths were investigated in the stands of Zizania latifolza populations of the littoral zone of Lake Paltangho, Korea. Any significant differences in sediment chemistry were not found along water depth, although sand content decreased slightly with increasing depth. Shoot density of Zizania latqolia decreased with increasing water depth. In shallower water, many of the short shoots died in the early growth stages. The morphology of shoots was taller and heavier in deeper water. The distributions of shoot heights became negatively skewed and leptokurtic as plants grew, and these changes occurred in the earlier growth stages in deeper water. The standing crop of shoots increased with increasing water depth. These results suggest that Zizania lattfolia has a growth strategy for adjustment to deep water through decreasing shoot density and increasing height.

Purpose: This article describes a case of the successful non-surgical management of a periodontally compromised maxillary premolar. Methods: A combination therapy, including root planing, occlusal adjustment, and tooth splinting, was applied. Clinical and radiographic examinations were performed during the 16-month follow-up period. Results: All periodontal parameters were improved. There were dramatic decreases (3-6 mm) in the probing pocket depth, tooth mobility, and marginal bone loss. Interestingly, gradual resolution of the periapical radiolucency and alveolar bone regeneration were observed in the radiographs, and the periodontal condition was maintained during the follow-up period. Conclusions: Within the limits of this study, these results demonstrate the importance of natural tooth preservation through proper periodontal treatment and occlusal adjustment of the periodontally compromised tooth, which is typically targeted for tooth extraction and dental implantation.

The purpose of this study was to explore the parenting experiences of mothers of disabled children. The study focused on how mothers of disabled children prepared for their children's transition to elementary school and how they experienced their children's adjustment to school. Twenty mothers of children with developmental or intellectual disabilities participated in the study. Each mother had experienced an inclusive education program at an elementary school for more than a year. Twelve mothers have children with intellectual disabilities and eight have children with developmental disabilities. Individual in-depth interviews were carried out to collect qualitative data. To analyze the data, the research followed the phenomenological analysis method of Giorgi. The results showed that mothers of disabled children were actively involved with inclusive day care centers and therapy programs to prepare for children elementary school. Most wished to send their children to a general elementary school with an inclusive program, although decision making was not easy. When their children entered elementary school, some mothers observed their children's struggle with school and their peer relationships. They sought support from teachers and other mothers. These mothers showed a desire for their children's social independence. This study highlighted the necessity to develop support programs for disabled children and their mothers.

The purpose of this study is to understand married female immigrants' life adjustment process in Korea by explaining the resources to which they have access and how they use them. The data were collected through in-depth interviews with ten female participants who have more than one child, have participated in programs of the multicultural family support center, have work experience, can communicate with Koreans, and live in Daegu. The major findings are as follows. The participants' personal resources differed. English language skills were very useful resources for making money and for earning the respect of family members and others. However, the participants without English language skills had sincerely and actively tried to learn the Korean language and gain bilingual competence. The participants obtained diverse family resources from their husbands and parents-in-law after adapting themselves to perform their gender role. Further, the participants used the social resources offered by public support systems as a starting point for learning the Korean language in their early adaptation process, and formed personal networks with staff members at the multicultural family support center. The results show that the participants used many kinds of resources for acculturation by interacting positively with their environment. Moreover, the resources from diverse levels of their environments affected their acculturation process.

This study was conducted to propose an insight into the appropriateness of hospital length of stay(LOS) by developing a severity-adjusted LOS model for patients with pneumonia, organism unspecified. The pneumonia risk-adjustment model developed in this paper is based upon the 2006-2010 the Korean National Hospital Discharge in-depth Injury Survey. Decision tree analysis revealed that age, admission type, insurance type, and the presence of additional disorders(pleural effusion, respiratory failure, sepsis, congestive heart failure etc.) were major factors affecting the severity-adjusted model using the Clinical Classifications Software(CCS). Also there was a difference in LOS among the regional hospitals, especially the hospital LOS has not been efficiently managed in Gyeongsangbuk-do, Jeollanam-do, Jeollabuk-do, Daejeon, and Busan. To appropriately manage hospital LOS, reliable statistical information about severity-adjusted LOS should be generated on a national level to make sure that hospitals voluntarily reduce excessive LOS and manage main causes of delayed discharge.

The purpose of this study was to investigate the relationship among peer relation disposition, relationship maintenance effort and school adjustment of gifted students and non-gifted students. And then the final purpose of the study is to give suggestions to help improving gifted students' peer relationship and their school adjustment. For the study, 175 gifted students and 179 non-gifted students in grades 4 and 6 of 5 elementary schools in urban areas were assessed on their peer relation disposition, relationship maintenance effort and school adjustment. The results are summarized as follows. First, gifted students were significantly higher than that of the non-gifted students as a whole. Second, in the correlation among peer relation disposition, relationship maintenance effort and school adjustment, peer relation disposition and relationship maintenance effort showed a significantly positive correlation with all the subvariables of school adjustment. Third, Sympathy-Acceptance disposition was the most influential factor for gifted students, and Independence-Responsibility disposition was the most influential factor for non-gifted students. Finally, the cluster analysis results based on the peer relation type of the gifted and the non-gifted suggested four meaningful clusters. And the four clusters showed significantly differences with all the subvariables of school adjustment. Implications of the study were discussed in depth related to the gifted education practices.

The purpose of this study is to understand the adjustment process of families adopting an older child, and to generate a substantial theory. To achieve this purpose, we conducted in-depth interviews with mothers adopting an older child and analyzed data with qualitative analysis approach. From the analysis, theoretical model has been made, and the model includes the adoptive families' diverse experiences, barriers to adjustment as well as resources and strategies that they mobilized and used for smooth adjustment. Their experiences in the process of adjustment consisted of five phases: unfamiliar meeting, shock, fighting alone without support, control, and stability. Barriers to adjustment process were composed of adoptees' problem behaviors, loss of time, lack of preparation, lack of experiences, repetition of the vicious circle, withstanding alone, improper resources, lack of support, and being criticized. Resources and strategies that families adopting an older child utilized were individual resources and ability such as rearing experiences, intellectual ability, willingness, belief, and perspective change; family system such as spouse and other offsprings; informal support system such as extended families, relatives, friends, neighbors, and other families adopting an older child; formal resources such as adoption workers and helping professionals. From our results, we suggested policy and practice guidelines to help adjustment experiences for families adopting an older child.
