A questionnaire on "atomic models and electron configuration" was performed on 34 of 11th grade and 38 of 12th grade students who took the Chemistry-II course in order to examine the degree of learning achievement. Also eight Chemistry-II textbooks published in the 6th curriculum were analyzed for the similarities and differences in dealing with this topic and possible improvements were discussed in conjunction with the questionnaire. The results of this questionnaire showed that the degree of learning achievement on the topics between two different classes were not much different in general, although a little difference was found. This indicates that the topics have been taught in early 11th grade but subsequent supplemental teaching has not been performed. To study on the topics of "atomic models and electron configuration" effectively and systematically, knowledge on the basic spectroscopy and quantum mechanics should be preceeded. However this could be practically difficult under the current high school curriculum. Therefore It would be necessary to describe the basic concepts for the quantum mechanics and spectroscopy schematically in the "Reference Materials" section of the textbook, even if it is not very long. On the other hand, the Chemistry-II textbooks analyzed in this work reveal, in general, to have the similar organization and explanation modes. However it has been analyzed that a connection between the Bohr and electron-cloud atomic models might be insufficient or position of electrons might be possible to be misunderstood by students in some textbooks.

There are many different job skill evaluation scales, but the development of the job skill scale for the workers in the local child care centers has much to be improved. The purpose of this study is to develop and validate the job skill scales for the workers of local child care centers. It is also the purpose of this study to specify the scope of work for such workers and define the job skills to develop a tool to evaluate the job skills of them, eventually. As for the study method, the researcher conducted literature review and Delphi survey to extract the job skill factors. Then, after going through a discussion with an expert, the researcher developed the preliminary questions to verify the validity of the contents and the certification validity. For this, a survey was conducted with the workers in local child care centers across the country, and a total of 221 questionnaires have been used for analysis. With this, a total of five job skill factors for such workers were identified, based on which 20 questions were developed to constitute the scale. The sub-factors identified were student supervision, program planning, child education, administrative works, and link-up with the local community. The confidence level of the scale developed in this study was Cronbach ${\alpha}=.940$(N=221). With the scale of the job skills of the workers in local child care centers, it would be possible to develop various job skill programs. And, this would be able to be used for evaluating the job skill levels of not only the workers in the local child care centers but also other child-care service providers.

This study is intended to improve parental capacity from the viewpoint of children's happiness. It extracts a core parental capacity for children's happiness from the international index such as OECD well-being, UNICEF Children's welfare, International survey of children's well-being, and Korean children's key index. Based on the extracted core parental capacity, this study developed a self-checklist aiming to perceive parents' capacity status and suggest a political plan in order to improve parents' capacity for children's happiness. The self-checklist has a total of 66 questions and is composed of 7 domains; Child development, Health and Safety, Family relation, Physical and material environment, Play, Guidance in life, and Community engagement. The results from the survey are as follows. The domains of Development of children as well as Health & Safety are reported as the highest value at 4.1 point; on the contrary, those of Guidance in life and Community engagement are reported as the lowest value at 3.8 point. In terms of age, it was reported that the capacity of parents under 35 years-old was better than that of parents over 35 years of age.

Purpose: This study is aimed to investigate perceptions of caregivers and medical staff toward do not resuscitate (DNR) and advance directives (AD). Methods: Participants were 141 caregivers and 272 medical staff members from five general hospitals. A questionnaire used for the study consisted of 20 items: 14 about DNR perceptions, three about AD, one each for age, gender and employment. Results: Both medical staff and caregivers strongly recognized the need for DNR and AD, and the level of recognition was higher with medical staff than caregivers (DNR ${\chi}^2=44.56$, P=0.001; AD ${\chi}^2=16.23$, P=0.001). The main reason for the recognition was to alleviate sufferings of patients in the terminal phase. In most cases, DNR and AD were filled out when patients with terminal conditions were admitted, and patients made the decisions by consulting with their guardians. Medical staff better recognized the need and for growing demand for guidelines for the DNR and AD decision making process than caregivers (${\chi}^2=7.41$, P=0.0025). Conclusion: This study showed that patients highly rely on their caregivers when making decisions for DNR and AD. Thus, it is important that patients and caregivers are provided with objective information about the decisions. Since participants' strong support for DNR and AD was mainly aimed at alleviating patients' suffering, further study is needed in the association with hospice care. Medical staff also needs to understand the different views held by caregivers and fully consider the disparity when informing patients/caregivers to make the DNR and AD decisions.

There have been much efforts to reconstruct the science curriculum focusing on Disciplinary Core Ideas(DCI) in many countries such as America and Europe, the most practical effort has been to design a curriculum with learning progressions(LPs). LPs describe stepwise how students can systematically move toward the understanding of more sophisticated ideas or scientific activities and explain in succession the process of understanding the ideas while the students learn. In this study, a LP for ecosystems has been developed, and the developed LP is then evaluated accordingly. The Ecosystem is one of the DCI of the life science in Next Generation Science Standards(NGSS). The development process of the LP was set at step 4(Development, Assessment, Analysis, and Amendment), and developed through an iterative process of sequences. As a result of analyzing the developed LP, an assessment based on the LP provides reliable information to identifying student ability. This study proposes the development process of the LP and its methodological aspects to use Core Achievement Standards, Ordered Multiple-Choice items and the Rasch model. In addition, using the empirically proven LP suggests a way of strengthening curriculum linked to educational content, teaching methods and assessment. Utilizing the proposed development process in this study will be to present the standard into the direction of becoming part of the curriculum. Currently, the state of domestic research for the LP is still lacking. This study determined the development process of the LP and the need to conduct future research on the LPs.

In this study, the early suicide prevention program was applied to the elementary school students and compared the prior & post effect of the program, and verified the status of psychology change like emotional status, or temptation to take a suicide, and presented the possibility as a suicide prevention program. The period of adolescence is the very unstable period in the process of growth being cognitively immature, emotionally impulsive period. It is the period emotionally unstable and unpredictable possible to select the method of suicide as an extreme method to escape the reality, or impulsive problem solving against small conflict or dispute situation. Many stress of the student such as recent nuclear family, expectation of parents to their children, education problem, socio-environmental elements, individual psychological factor lead students to the extreme activity of suicide in recent days. In this study, the scope of stress experienced in the elementary school as well as idea and degree of temptation regarding suicide by the suicide prevention program were identified, and through prevention program such as meditation training, breath training and through experience of anger control, emotion-expression, self overcome and establish positive self-identity and make understanding Self-control, Self-esteem & preciousness of life based on which the effect to suicide prevention was analyzed. The study was made targeting 51 students of 2 classes of 6th grade of elementary school of Goyang-si and processed 30 minutes every morning focused on through experience & activity of the principle & method of brain science. The data was collected for 20 times before starting morning class by using Suicide Probability Scale(herein SPS-A) designed to predict effectively suicide Probability, suicide risk prediction scale, surveyed by 7 areas such as Positive outlook, Within the family closeness, Impulsivity, Interpersonal hostility, Hopelessness, Hopelessness syndrome, suicide accident. Analytical methods and validation was used the Wilcoxon's signed rank test using SPSS Program. Though the process of program in short period, but there was a effective and positive results in the 7 areas in the average comparison. But in the t-test result, there was a different outcome. It indicated changes in the 3 questionnaires (No.7, No.14, No.19) out of 31 SPS-A questionnaires, and there was a no change to the rest item. It also indicated more changes of the students in the class A than class B. And in case of the class A students, psychological changes were verified in the areas of Hopelessness syndrome, suicide accident among 7 areas after the program was processed. Through this study, it could be verified that different results could be derived depending on the Student tendency, program professional(teacher in charge, processing lecturer). The suicide prevention program presented in this article can be a help in learning and suicide prevention with consistent systematization, activation through emotion and impulse control based on emotional stress relief and positive self-identity recovery, stabilization of brain waves, and let the short period program not to be died out but to be continued connecting from childhood to adolescence capable to make surrounding environment for spiritual, physical healthy growth for which this could be an effective program for suicide prevention of the social problem.
