The purpose of this study is to explore the relationships that a popular three year old child has with other children and teacher. One popular child was selected among thirteen children using peer-nomination method and participated in this study. During free choice play time, the popular child's various activities and interaction patterns were observed and analyzed. The popular child in this study had a steady intimate friendship with his best friend most of the time. However, he showed a tendency to behave as he pleased and give orders to other children who he was not in a close relationship with. He did some deliberate and premeditated acts to get praise and love from his teacher. The teacher's compensations also reinforced his intentional actions.

In this paper, a shape design sensitivity analysis(DSA) method is presented for Mindlin plates using an isogeometric approach. The isogeometric method possesses desirable advantages; the representation of exact geometry and the higher order inter-element continuity, which lead to the fast convergence of solution as well as accurate sensitivity results. Unlike the finite element methods using linear shape functions, the isogeometric method considers the exact normal vector and curvature of the CAD geometry, taking advantages of higher order NURBS basis functions. A selective reduced integration(SRI) technique is incorporated to overcome the difficulty of 'shear locking' phenomenon. This simple technique is surprisingly helpful for the accuracy of the isogeometric shape sensitivity without complicated formulation. Through the numerical examples of plate bending problems, the accuracy of the proposed isogeometric analysis method is compared with that of finite element one. Also, the isogeometric shape sensitivity turns out to be very accurate when compared with finite difference sensitivity.

Recently, the cases of archiving for digital contents are being increased throughout the world. Owing to the characteristics of digital contents including the issues on volatile property and authenticity, preservation weakness, and aging in the reproductive tool, it requires special management for long-term preservation. A successful digital archiving seems to be possible in the stage-oriented practice through the cooperation of interested organizations based on the systematically established and stipulated policy. This is the basic study that was designed for the establishment of the policy on digital contents archiving in KISTI(Korea Institute of Science and Technology Information), which is a representative organization for the distribution of science and technology information. By investigating and analyzing the cases of overseas policies on digital contents archiving, it intended to understand the framework of digital archiving policy while suggesting measures on the macroscopic items that were included in the archiving policies through the interview conducted to expert groups.

The characteristics of environmentally friendly block, roughness, erosion, stability and dissolved oxygen(DO) were investigated by hydraulic experiment. It was found that the roughness of A-block was lower than I block and A block was more stable to the variation of flow. So it is expected that A-block will be more effective to the channel flow. It was also found that the erosion of channel bed was very small or rarely occurred and stable in the case of 3-dimensional A-block filled with sand. And 3-dimensional A-blocks assembled with A-blocks were more stable against the flow force than I block because of the united force of A-blocks. When the bed of channel was paved with 3-dimensional A-blocks, DO was increased higher than I block. So it is expected that A-block will be more advantageous to underwater environment than I block.

A collection policy (or a collection development policy) is a document that archival institutions must have to allow them to build their collections legitimately and consistently. Digital archives often lack sustainable financial and systematic supports. Thus, it is especially important for digital archives to have a policy for consistent collection activities. Digital archives have a different set of characteristics from physical records, and these characteristics should be considered in a collection policy. This study was initiated to create such a policy for the No Gun Ri Digital Archive. It reviewed existing literature for collection policies in archives and digital archives. Moreover, it examined several cases of digital archives and their policies to identify the necessary elements as well as the legal and procedural coverages for digital content and services. Furthermore, it studied the unique characteristics of the No Gun Ri incident and the No Gun Ri Digital Archive. Based on such investigation, a collection policy for the No Gun Ri Digital Archive was suggested. It is believed that suggesting a practical collection policy will provide a useful precedent for future digital archive projects.

Because archaeological artifacts are often destroyed during physical excavation, the data archaeologists gather in the field is rich with research potential. Few in Korea have paid attention to digital archives for archaeological data or argued for their development. This paper considers the significance and necessity of archaeological data and digital archives for its preservation and access. It also raises awareness of the need to develop a Korean national archaeological data digital archive. The paper first overviews the nature of the archaeological discipline, data, and digital archives. Then it investigates well-known, global cases involving digital archiving of archaeological data. Based on these foundations, the paper discusses principal and prior challenges to developing a Korean national archaeological data digital archive.

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. As for family income, it was revealed that the order of parents' capacity generally depends on the family income.

Recently, identification of the extremely stressed condition of children is an essential skill for real-time recognition of a dangerous situation because incidents of children have been dramatically increased. In this paper, therefore, we present a model based on machine learning techniques for stress status identification of a child by using bio-signals such as voice and heart rate that are major factors for presenting a child's emotion. In addition, a smart band for collecting such bio-signals and a mobile application for monitoring child's stress status are also suggested. Specifically, the proposed method utilizes stress patterns of children that are obtained in advance for the purpose of training stress status identification model. Then, the model is used to predict the current stress status for a child and is designed based on conventional machine learning algorithms. The experiment results conducted by using a real-world dataset showed that the possibility of automated detection of a child's stress status with a satisfactory level of accuracy. Furthermore, the research results are expected to be used for preventing child's dangerous situations.

As we enter the 21st century, interests in health and quality of life have grown gradually. In this study, we analyzed the data in response to each questionnaire for life management and sub-health among targeted members of a particular group. The results of the analysis of life management have found no difference between genders at the 5% of significance level. In respect to gender, a differential analysis of sub-health, however, has shown a gender difference in which female students had significantly worse health conditions than male students in the areas of immune system, intestine, cerebral nerve, hormone, and urinary system. Moreover, we also have found no significant difference among colleges in terms of life management and sub-health. In conclusion, it was shown that sub-health is closely related with life management.

The purpose of this study was to compare the breast feeding practice rates and mothers' breast feeding empowerment in preterm (gestation age [GA]<34), late preterm ($34{\leq}$GA<37), early term infants ($37{\leq}$GA<39). We surveyed 33 preterm, 22 late preterm, and 30 early term infants at a 'Baby-Friendly Hospital' in D city. The data were collected from October 1st, 2008 to February 28th, 2010 through the medical records of the infants and their mothers. We also checked the mothers' breast feeding empowerment at discharge day. The rate of breast feeding in the late preterm and preterm infants was significantly lower than that of the early term infants. The score of mothers' breast feeding empowerment in the late preterm and preterm infants was also significantly lower than that of the early term infants. The breast feeding education program is required for the mothers who have preterm and late preterm infants considering the low rate of breast feeding.
