In order to help elementary students understand the astronomical unit in depth, this study applied backward design 2.0 to check the effect on students' science academic achievement, performance evaluation, and science class satisfaction. As a result of the study, there was no statistically significant difference in the science achievement test, but the average score of the experimental group has improved. As a result of the performance evaluation test, there was a statistically significant difference because the feedback was well provided through the process-focused assessment and it helped in-depth understanding. As a result of the science class satisfaction test, there was a statistically significant difference in the areas of science curriculum and peer relation except for the science teacher area. This is because a differentiated science curriculum was designed through analysis of achievement standards, and various teaching methods of student-centered were implemented to reach achievement standards. We hope this study will focus on the impact of backward design 2.0 on learners in elementary science classes and help find ways to effectively apply backward design 2.0 in the field.

The purpose of this study was to examine whether adolescents' parental rule obedience moderates the relationship between maternalmonitoring and problem behavior (drinking and vandalism). Participants were 398 adolescents attending a middle school (6th through 8th grades) in a semi-rural mid-Atlantic community in the USA. Data were collected by questionnaires including items regarding relationships with parents, problem behavior, and peer relationships. Hierarchical multiple regression was usedto analyze the data. Results indicate that maternal monitoring is negatively related with adolescent drinking and vandalism. However, the negative relationship varies as a function of adolescents' parental rule obedience. The relationship was stronger among adolescents with lower level of parental rule obedience than among adolescents with higher level of parental rule obedience. Findings from this study suggest that research on maternal monitoring during adolescence needs to take adolescents' personal characteristics into account to better understand the process. They also suggest that parents could lower the possibility that their children's will be involved in drinking and vandalism by maintaining quality relationships with their children because children are more likely to internalize their parents' rules and standards when they have positive relationships with parents.

Purpose: The purpose of this study was to analysis the effects of nasal Continuous Postive Airway Pressure (nCPAP) for preterm infants using systematic review and meta-analysis. Methods: Thirteen peer-reviewed journals including preterm infants and apnea and nCPAP published between 1973 and 2013 were included. Effect size and statistics of homogeneity were done using STATA 10.0. Results: The design for 9 studies was Randomized Control Trial. In most of studies the pressure of nCPAP was set to 4-6 cm$H_2O$. The effect size of 5 studies for the effect on apnea rate using nCPAP compared to nasal Intermittent Positive Pressure Ventilator (nIPPV) showed that the Standardized Mean Difference (SMD) was -0.11 and was not significantly different (Z=0.41, p=.680). But the difference in nCPAP for nasal Synchronizes Intermittent Positive Pressure Ventilator (nSIPPV) (subgroup) was significant (SMD=-.44). The effect size of 7 studies on effect for ventilator weaning of using nCPAP compared to nIPPV showed the Risk Ratio (RR) as 1.60 and was not significantly different (Z=1.12, p=.268). But the difference between nCPAP and nSIPPV (subgroup) was significant (RR=3.94). Conclusion: The results indicate a need for an advanced care system and suggest continuous studies of apnea in preterm infants.

This study aimed to explore the life experiences of youth with intellectual disabilities in residential facilities. The residential facilities in this study include large scale residential facilities where many residents live and a group home where a few residents live. This study used a qualitative research method; the youth participants were selected from the recommendations of professional groups, and interviewed using the focus group and individual interview methods. In addition, social workers and parents were interviewed to complement interviews of youth with intellectual disabilities. According to the results, the following main themes were extracted from the experiences of youth with intellectual disabilities who live in residential facilities: 'restricted lives by strict rules', 'limitation of individual lives and choice experiences', 'not being respected' at large scale residential facilities, and 'starting independent living', 'a still hardship of independence', 'a tranquil life like home', 'difficulties of communal living' at the group home. Also, they have common experiences in both types of residential facilities: 'depending on each other', 'missing their family', 'being excluded from peer groups at school', 'not wanting to be known as living at residential facilities'. The implication of this study results are for the policy making, and the actual practices were discussed focusing on their right and well-being.

The goal of this paper was to understand the skill-up experiences of ex-participants of the customized training program in Technical High Schools for Small and Medium Business during first 2 years in Company through qualitative interviews with 3 purposefully selected ex-participants. Their core skill-up experience in this period was assumed as the shift from' dependent worker' to 'independent worker' on the base of literature review. The results of this study were following : 1. The small and medium companies offered a few formal training for newcomers, production-site orientation through short job rotation, linking them with skilled workers and job manuals or job standards. 2. Authentic skill-up experiences were combined with a structured reprimand, peer learning, deep learning through reflection on one's own experiences. 3. There were a few handicap conditions that disturbed their skill-up activities: the skilled worker don't open their skill toward new corner; the ex-participants in company had no time to learn anything meaningful to up-grade their competency.

The purpose of this study is to inquire into the changes to the emotional intelligence of young children by giving them pleasure and memory through the program of ecological experience. A survey was made on 40 young children in two classes out of 5-year-old children's classes in nurseries located at Chungcheong-do. They were divided into the experiment group and control group to consist of 20 persons, respectively. For young children of the experiment group, the experiment was conducted while observing and experiencing through the division of the group into 5 persons on fixed days according to the program of ecological experience. Analysis showed that the program of ecological experience in the experiment group relatively higher effect of increase for the emotional intelligence of young children, and the use of self emotion, the cognition and consideration of other's emotion, the cognition and expression of self emotion, the regulation and impulse control of emotion, the relationship with teacher and the relationship with peer by sub-factors than that in the control group. In other words, close relationships with nature and inquiry instruction of ecological experience have provided the attitude-based formation living together with the understanding of natural world and eco-friendly attitude, the cognition of ecological crisis and social cooperation that couldn't feel in indoor education. Consequently, the program of ecological experience should prove useful for the emotional intelligence of young children.

In this thesis, girls' suicidal mentality which appears in some adolescent novels was sought. We can conclude like these: first, in the novel, Elegant Lies written by Ryeo-ryung Kim, the girl named Wha-yun leaves out Cheon-ji not to be left out alone by her companies. Wha-yun has succeeded in giving an ugly impression of Cheon-ji to the peer girls around her by exercising relational aggression. As a result, Cheon-ji sees herself as a meaningless being and after recognizing that she can't change the situation, she shows psychology of escape. Second, in the novel, Goodbye, from Kilimanjaro written by Ok-soo Lee, Sung-min Yoon's girlfriend Soo-hee born and grown in Africa lives with trauma from her mother's death. As her step-mother suppressed her not to keep in touch with the pet animals, Soo-hee got depressed and out of energy. Parental oppression and verbal violence can let the girl activates self-punishment and lead to suicide. Third, in the novel, Thursday, in Cyprus written by Chae-ran Park, girls could use suicide as a negotiation agenda. Adolescents could commit suicide even if their trivial requests are rejected. In these situations above we can read anticipation of compensation, retaliation and self-punishment mentality.

This study examines the effects of reading and story sharing through fairy tales on young children's character development in their role play using natural materials. To achieve this, 40 5-year-old children at early childhood educational institutes in Daejeon were tested 16 times for 8 weeks. The results were as follows. First, their role plays using natural objects through reading and talking had a positive effect on their personality cultivation. Second, there was no experimental difference in their prudence and filial piety of basic behavioral items, but their cleanliness and patience were proven effective in the experiment. Third, all their justice, conscience and service indicating their sociality-related friendship, kindness, gentleness and morality were proven effective in the experiment, which their role plays using natural objects through reading and story sharing through fairy tales had an educational effect on improving their sociality and morality through peer interaction. This suggests that their mind to improve social virtues with an exchange of emotions, particularly, treat natural role play in a friendly way, their public promises to cherish life, and their ethical virtues to obey the rules in the process of consideration, appreciation, understanding and help through mutual communication and cooperation in forest experience activities are very effective from an educational perspective.

Delivering multicast stream is one of the cost-saving approach in the large scale VOD environment. Because implementing VCR-like interactions for user's convenience in the multicast streaming system involves complex problems, we need the proper solutions for them. In this paper, we propose a hybrid scheme which uses the general P2P and the patching scheme with the Collaborative Interaction Streaming Scheme(CISS). CISS provides jumping functionability to the appropriate multicast session after VCR-like interaction in the environment in which multiple peers transmit VCR-like interaction streams to the VCR-like functionability request node to reduce the loads generated by frequent join or departure of peers at the multicast tree during providing VCR-like functionability. Therefore, with the proposed scheme we can distribute network traffic and reduce control overhead and latency. And to evaluate the performance of proposed scheme we compare it in the aspect of the performance of streaming delivery topology, control overhead and streaming quality with P2Cast[10] and DSL[11]. The simulation result shows that proposed P2Patching reduces about 30% of process overhead and enhances about $25{\sim}30%$ of streaming quality compared with DSL.

This paper aims to understand the conceptual definition and the characteristics of reality shock in new graduate nurses. We analyzed the data using the hybrid model, initially introduced by Schwartz-Barcott and Kim. The data used in this study were collected from six recently graduated nurses who work in S-si and G-si. Another part of the data was obtained from literature review regarding Reality Shock. We categorized Reality Shocks in recently graduated nurses into nine attributes within a three-dimension model. The dimensions include "cognitive", "emotional", and "situational" domains. The cognitive domain is to be aware of the factor that causes Reality Shock. The emotional domain is the negative emotional responses that appear when facing a situation causing Reality Shock. The situational domain is the sort of circumstantial situations that cause Reality Shock. Reality Shock is defined as recently graduated nurses having several negative emotions, such as powerlessness, difficulty in peer relationships, confusion, and pressure due to (i) the differences between reality of nursing and what they have learned in school, (ii) the differences between an ideal situation and the real situation, (iii) the lack of expertise of senior nurses, (iv) a situation without the respect from colleagues, and (v) the overloaded role compare with the expectations. In conclusion, we provide a guideline for establishing a strategy to reduce Reality Shock in recently graduated nurses by identifying the concept of Reality Shock.
