This study, based on understanding the play features of the participants, explores early children's peer-relation strategies of maintaining and altering play frame and understanding the meaning of the strategies. Free play of 5-year-old children's was observed. The child-care center was visited 1 or 2 days a week, from March to October, 2012. The data collected were based from field notes, interviews with participants, their workbooks and more. The participants used strategies such as 'refusing', 'incapacitating', 'interpreting in a way to sympathize', and 'changing the rules of play' to maintain the play, whilst 'tell-on', 'being on the same side', 'accepting 3rd party' features were used to alter play frame. Participants using these various play-frame strategies experienced life implications of 'dialectic of exclusion and selection' and 'quiver of boundary'. This study, specifying efforts of the children to maintain and alter the play frame, will provide an understanding of perception of "social exclusion" to children, which has been viewed negatively in the past. It will also benefit on-site teachers in helping them understand peer-relationship within children and provide a more in-depth intervention for peer-relationship issues.

The purpose of this study was to examine the relationship between maternal age and infant mortality in Korea(n=617,867). Data of Korean vital statistics linked National Infant Mortality Survey conducted on births in 1999 were used in this study. The odds ratios (ORs) of infant death by maternal age were estimated with the multiple logistic regression model, adjusting for gender, plurality, birth order, low birth weight, and congenital malformation. After adjusting for the relevant variables, the odds of infant death in the group of maternal age with less than 20 years(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98), 20-24 years(OR, 1.44, 95% CI, 1.23-1.69), 35-39 years(OR, 1.28, 95% CI, 1.11-1.46), and more than 40 years(OR, 1.94, 95% CI, 1.53-2.45) was higher than that of reference group(25-29 years). In conclusion, the higher infant mortality in the group of maternal age with less than 25 years and more than 35 years in Korea appears to be due to higher proportion of low birth weight and pre-term birth. Prenatal care intervention programs which tackle biological factors for advanced maternal age and address socio-economic problems and social stigma for early maternal age should be devised.

The purpose of this study was to identify characteristics of vegetation structure, vegetation succession, and species diversity of artificially planted Chamaecyparis obtusa (CO) stands. The study was carried out by performing vegetation survey for eight CO stands located in Jeollanam-do Province, Korea. Analysis on vegetation classification and ordinations of the stands was conducted using the data from the vegetation survey, and as a result, the stands were classified into five types of communities. Community I showed a considerably lower index of species diversity when compared to other communities because the canopy of the dominant CO was so highly dense that the low-height vegetation was not able to develop or the low-height vegetation almost disappeared due to elimination of weed trees. Meanwhile, the Community II - IV had relatively higher indices of species diversity because various native tree species mixed with the low-height vegetation and competed with each other in the understory and shrub layers to some degree of stability or in their early stage of vegetation development. Community V, lastly, showed higher use intensity as a recreational forest, thus developing simpler vegetation structure on account of artificial intervention. There was positive correlation between photosynthetically active radiation entering the forest floor, number of observed species and index of species diversity. Such characteristics of vegetation structure in CO stands are closely associated with forest management and prescription for planting reforestation, thinning, and brush cutting in the past. There was a slight difference in vegetation structure and species diversity by communities, based on rotation time of the vegetational succession, process of disturbance frequency and disturbance, development, and maturity by planting CO stands. However, when compared to natural forests, the CO stands showed simpler vegetation structure. Because artificial forests are vulnerable in ecosystem service with lower species diversity, a drive for ecological management is needed for such forests to change into healthy ecosystems that can display functions of public benefit.

This article investigates 230 public assistance recipient elderlies and 354 community elderlies in order to find out the current status and influencing factors on elder abuse. It surveyed at Gwangju metropolitan city. The result from the research were 1) the degree of elder abuse is generally low, and the primary type of abuse is psychological abuse and neglect. The victims of abuse experienced psychological pain rather than physical pain. 2) the abuser are mainly in early forties, and very unstable economically. 3) based on personal characteristics of the recipient and non-recipient elderlies, there are significant differences between respondents' sex, age, education level, income, ADL, IADL, chronic disease, depression, social support, and number of friends. 4) the factors affecting elder abuse of public assistance recipient elderlies are depression, alcohol, social support(elderly-related factors), alcohol, childhood abuse(abuser- related factors), and emotional relationship, number of family members(family- related factors). And, the factors affecting elder abuse of community elderlies are childhood abuse, social support(elderly-related), relationship with victims(abuser -related), and emotional relationship(family-related). Finally, the research recommends that differential intervention strategies are needed in order to prevent elder abuse of the public assistance recipient elderlies and the community elderlies.

Purpose: The rapid response team is a patient safety system that detects symptoms and signs of deteriorating inpatients and provides intervention and treatment. This study analyzed the factors influencing the activation time of the team. Methods: This is a descriptive correlation study that analyzed the electronic medical records of patients activated by the rapid response team. The collection period was from January 2014 to December 2017. We analyzed 278 pieces of data activated by the rapid response team for patients aged 16 years or older at C University S Hospital in Seoul. We employed the SPSS 23.0 program for data analysis. Results: The reasons for activation of the rapid response team were oxygen saturation of less than 90.0%, other causes, and change in consciousness. The most common diagnosis of activated patients was respiratory failure (32.4%). The average activation time was 153.43±286.05 min. The activation time was shortest during convulsions (13.29±7.32 min). For patients with a history of kidney disease (B=0.58, p=.008), in case of surgery (B=0.55, p<.001), if the first symptom is mediated by the physician (B=0.53, p=.007) the active time is often extended. On the other hand, activation time is reduced when consciousness changes (B=-0.51, p=.002), especially when oxygen saturation is below 90.0% (B=-0.64, p<.001). Conclusion: Based on the results of the study, it is expected that patients deteriorating in the general ward would be recognized early, which will help in the effective activation of the rapid response team.

Distraction osteogenesis(DO) is a surgical method of bone formation that involves an osteotomy and sequential stretching of the healing callus by gradual movement and subsequent remodeling. DO is used to correct facial asymmetry, such as in patients with hemifacial microsomia, maxillary or mandibular retrusion, cleft lip and palate, alveolar defects, and craniofacial deficiency. It is accomplished with the aid of a distraction device, which is secured with screws placed directly into bone, for a predetermined length of time. Hemifacial microsomia is characterized by unilateral facial hypoplasia, often with unilateral shortening of the mandible and subsequent malocclusion. Patients with hemifacial microsomia and facial asymmetry have a vertically short maxilla, tilted occlusal plane, and short mandible. Early treatment is necessary to avoid subsequent impaired midfacial growth. The standard treatment of these malformations consists of the application of bone grafts, which can lead to unpredictable growth. The new bone-lengthening procedure represents a limited surgical intervention and opens up a new perspective for treatment, especially in younger children with severe deformities. This report describes a case of hemifacial microsomia(Type-II left-sided hemifacial microsomia). The patient, a 10-year-old child, visited our clinic for facial asymmetry correction. He had a hypoplastic mandible, displaced ear lobe, 10 mm canting on the right side, and malocclusion. We planned DO to lengthen the left mandible in conjunction with a Le Fort I osteotomy for decanting and then perform a right intraoral vertical ramus osteotomy(IVRO). Progressive distraction at a rate of 0.5 mm/12 hours was initiated 7 days postoperatively. The duration of DO was 17 days. The consolidation period was 3 months. Satisfactory results were obtained in our case, indicating that DO can be used successfully for functional, aesthetic reconstruction of the mandible. We report a case involving DO in conjunction with orthognathic surgery for correcting mandibular hypoplasia with a review of the literature.

Purpose: As dementia progresses, cognitive function decreasing leads to memory loss, speech degradation, time and space degradation and judgment degradation, which causes difficulties in carrying out tasks related to daily life. It was said that community-based non-drug intervention therapy for early dementia patients was important to participate in entertainment treatment, including activities such as awareness and exercise therapy, exercise rehabilitation, aerobic exercise, and art. Methods: This study conducted 15 experimental and 15 control groups(experimental group : Fumanet exercise, control group : general occupational therapy) for eight weeks at the Daycare Center in Gyeonggi-do to find out the impact of the Fumanet exercise program on cognitive and depression functions of the elderly. The pre-post evaluation used KGDS, MMSE. Results: There were significant differences between the two groups in the function of menopause, memory recall, attention concentration and calculation, and depression, and no significant results were obtatined in memory registration, language function, understanding and fracture. The Fumanet movement was judged to be effective in improving cognitive function and reducing depression for the elderly with dementia. Conclisions: The Fumanet movement was judged to be effective in improving cognitive function and reducing depression for the elderly with dementia.

Normal eruption of the canine is important for the transition to the permanent dentition. Etiologies, including premature loss or delayed retention of deciduous teeth, neoplasm and abnormality of lateral incisor can cause impaction of the maxillary canine. Untreated canine impaction can result in malocclusion, cyst formation and obstacles in orthodontic treatment. The aim of this study is to evaluate location of the impacted maxillary canine and to identify correlation between location and management of the impaction including complications. Using panoramic radiographs and CBCT scan, images of 89 children diagnosed with impaction of the maxillary canine, location of impacted canines was evaluated. The choice of treatment and complications were investigated to identify correlation. Results show that the most commonly impacted location of the maxillary canine was in the mid-alveolar area, followed by buccal side and palatal side. Orthodontic traction was selected more frequently than the other treatments. As complications, displacement of adjacent tooth was occurred most frequently. Buccally impacted canines showed increased tendency towards displacement. The more buccally the canine was impacted, the less orthodontic traction was chosen as the treatment. The canine impacted mesially to the central incisor showed increased tendency to occur root resorption. Therefore, early diagnosis by periodic examination, appropriate treatment and intervention is required.

It is important to asess the risk factors of parenting and provide early intervention for promotion of the maternal caretaking ability. The purpose of the study was to identify the maternal burden of caretaking, the supporting and the educational need for the caretaking activities of the mother of infant. Sixty three mothers of infants who visited the wellbaby clinic of S university hospital and one health center during the period of November 1st, to 30th in 1996 comprised the subjects of this study, Data were gathered through the instruments that were developed by researcher. Statistical analysis of this study was used ANOVA and Pearson correlation. The results were as follows : 1) The mean score of the maternal burden of caretaking was 22.06. The maternal burden of caretaking was significantly high in the mothers who had vaginal delivery compare with the mothers who had caeserean section and in the muthers who gave artificial feeding compare with the group of breast or mixed feeding. 2) The mean score of the support need for the caretaking activities was 30.69. The support need for the caretaking activities was significantly high in the mothers who had the second child, compare with the mothers who had first or third child. And the support need for the caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'immunization' and 'prevention of accident' on the support need for the caretaking activities were relatively high. 3) The mean score of the educational need of caretaking activities was 29.3. The educational need of caretaking activities was significantly high in the mother who had the second child compare with the mothers who had first or third child. And the educational need of caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'emergency care' and 'prevention of accident' on educational need of caretaking were relatively high. 4) The maternal burden of caretaking was not correlated with the support need or the educational need of caretaking activities. But the support need of caretaking activities was significantly correlated with the educational need of caretaking activities. 5) The support and educational need of caretaking activities were significantly high in the mothers who wanted home care for caretaking their infants. Through the study, it was found that there is considerable maternal burden of caretaking as well as the support and educational need on the caretaking activities in the mothers whose child is young. Therefore developing the systematic and effective program is needed to meet the mother's need. The results of this study will be useful resources to develop the program. On the other hand, it can be recommanded that home health care will be one of the approach to support the mothers caretaking activities.

The purpose of this study was to examine the effects of the game application learning 8th graders' scientific attitude, which was utilized as a strategy to improve the teaching skills and methods in the lesson of 'the history of the earth and diastrophism'. The subjects of this study were 120 students of 8th grade at a middle school located in a metropolitan city in Korea. To start off with homogeneity of a group, this study recruited participants by the results of a diagnostic test taken early in the year and a mid-term examination taken at the end of April. As a result, a total of 4 male classes that showed similar results on the two tests were selected and divided into two groups: one in experimental and the other in control. In addition, the top 20% students and the low 20% students were chosen for comparison of their scientific attitudes based on the results of the mid-term examination. The traditional teachings were offered to the control groups while the experimental lessons with the game activities performed at the stages of application and summary in teaching were offered to the experimental groups over 10 periods. Results of the pre- and post-test on the students' scientific attitude demonstrated that there was a statistical significance between the two groups, which suggested that the experimental group showed a meaningful improvement in the scientific attitude after experimental intervention lesson activities with game applications. Also, the more meaningful improvement in the scientific attitude was found in the lower group than in the higher group. It implies that lessons with the game activities motivated the students to voluntarily participate in school science learning by enhancing their interests. Therefore, it is suggested that game application learning be a new teaching-learning material that helps to encourage learners to actively participate in middle school science learning.
