Wireless sensor network supporting healthcare environment should provide customized service in accordance with context information such as continuous location change and status information for people or movable object. In addition, we should consider data transmission guarantees a person's bio information and privacy security provided through sensor network. In this paper analyzes LEACH protocol which guarantees the dynamic self-configuration, energy efficiency through configuration of inter-node hierarchical cluster between nodes and key distribution protocol used for security for data transmission between nodes. Based on this analysis result, we suggested self-configuration routing protocol supporting node mobility which is weakness of the existing LEACH protocol and data transmission method by applying key-pool pre-distribution method whose memory consumption is low, cluster unit public key method to sensor node.

In the existing researches about the Internet and mobile phone addition for primary and secondary school students, the major addiction testing measurements are personal parameters such as obsession, self-efficacy, and self-control and environmental parameters such as parents, friends, schools, community factors, and mass media. Those researches have focused on the interaction objects between a student and him/herself, parents, friends, schools, or society. While the importance of time perspective has increased recently, there have rarely been the research that had focused on it in education arena. In this paper, we analyze how time perspective influences the Internet and mobile phone addiction levels of primary and middle school students. In order to do that, we surveyed 619 primary and middle school students and analyzed the results in this paper. And then, we renew the relative importance among existing factors for the two addictions and propose the way to prevent the two addictions.

The purpose of this study is to develop ceramic glazes for the pottery production by utilizing wasted white porcelain, celadon porcelain and bone china thrown away from the areas of Icheon and Yeoju. Most of Korean pottery manufacturers are located in the both areas. According to the XRF analysis, the wasted white porcelain contains over 67 % of silica. It is enough to make a transparent glaze without adding silica. The wasted celadon porcelain contains much $Fe_2O_3$, which is suitable for producing a celadon glaze. The wasted bone china contains 22 % of $P_2O_5$, which is suitable for making a milky white bone china glaze. As a result, it is expected that production of pottery glaze using the wasted porcelains will reduce pollution problems comes from the landfill, and obtain economic effects in terms of resources recycling. It is also expected to be utilized as alternative materials of imported ones.

The purpose of this study was to identify factors affecting maintenance of exercise among elderly with metabolic syndrome. In order to achieve this purpose, the study design was used a cross-sectional survey. Study participants were a total of 136 elderly with metabolic syndrome and they completed the questionnaire consisted of outcome expectations, exercise self-efficacy, exercise social support, physical activity environment, and exercise maintenance. The data was analyzed using frequency, $X^2$, t-test, and Logistic regression by SPSS Win 20.0 program. The study results had shown that factors affecting maintenance of exercise among elderly with metabolic syndrome, were gender, outcome expectation, and exercise self-efficacy. This study results indicated that the personal motivation such as self-efficacy and outcome expectation among elderly with metabolic syndrome was the most important factor to maintain their exercise. Therefore, we should consider on developing health promotion program to enhance the personal motivation such self-efficacy and outcome expectation for elderly with metabolic syndrome. In addition, this results would used to develop adequate nursing strategies for taking care them in the community.

In this paper, I am going to analyze a correlation of Jacques Lacan's Mirror Stage and the process of remediation on image media. It is because the remediation process of various digital media is letting people pass through one time of mirror stage again. Remediation for the Internet of traditional media, conflict with the virtual world and real world, identification that a virtual image changes a practical image is for it to be caused a remediation process by mutual link of various image media. The Narcissism which occurs in the relation a self with a idealized self searches a new own expression and forms a skillful mania culture. Reflexivity of active mania culture same as a Jacques Lacan's Mirror Stage is to be the possibility becoming the feature of media culture of today. However, if digital media culture generation spends extremely wasting time from the image media, these image media generations cannot grow into new future-type man. According to this, it is necessory to have a study on Visual Literacy that it is related to a Jacques Lacan's Mirror Stage.

The ozone data is one of the important environmental data for measurement of the atmospheric condition of the country. In this article, the Autoregressive Error (ARE) model and Neural Networks (NN) model have been considered for analyzing the ozone data at the northern part of the Gyeonggi-Do, Paju monitoring site in Korea. In the both ARE model and NN model, seven meteorological variables and four pollution variables are used as the explanatory variables for the ozone data set. The seven meteorological variables are daily maximum temperature, wind speed, relative humidity, rainfall, dew point temperature, steam pressure, and amount of cloud. The four air pollution explanatory variables are Sulfur dioxide ($SO_2$), Nitrogen dioxide ($NO_2$), Cobalt (CO), and Promethium 10 (PM10). The result showed that the NN model is generally better suited for describing the ozone concentration than the ARE model. However, the ARE model will be expected also good when we add the explanatory variables in the model.

The effects of molecular environments on photoisomerization of an azobenzene group were investigated using In-situ UV/Vis spectroscopy and optical anisotropy measurement technique. The reversible and repeatable photoisomeritation reactions of azobenzene were observed by irradiating the film containing 4-hydroxyazobenzene and by measuring absorption intensities of the characteristic bands of trans and cis isomers simultaneously. When the self-assembled monolayer with azobenzene groups was used as an alignment layer for a liquid crystal cell, the homeotropic alignment was induced due to their compact packing structures of azobenfene groups along the vertical direction of the substrate. By irradiating UV light on this cell, the trans-azobenzene groups change to cis-isomers through the photoisonlerieation and then resulting in the planar alignment of liquid crystal molecules.

The purpose of this study is to examine the effectiveness of flipped learning lesson on the human social behavior and social environment subject. In order to achieve this object, this study conducted qualitative analysis of class-evaluation and self-evaluation and quantitative analysis using the questionnaire. As a result, it was confirmed that flipped learning method works very effectively in the theoretical curriculum of social welfare. Participants assessed that their comprehension and presentation skills improved. In addition, their self-esteem improved after this class. However, this teaching may be rather negative for participants who had difficulties in pre-learning or a passive attitude. In order to improve this problems, the instructors should be prepared to make pre-learning better. As well as, they should prepare countermeasures for passive participants, and help interact well among the participants.
