A real time monitoring system from a PC has been developed which can be accessed through transmitted data, which incorporates an established low powered transport system equipped with a single chip combined with wireless sensor network technology from a three-axis acceleration sensor. In order to distinguish between static posture and dynamic posture, the extracted parameter from the rapidly transmitted data needs differentiation of movement and activity structures and status for an accurate measurement. When results interpret a static formation, statistics referring to each respective formation, known as the K-mean algorithm is utilized to carry out a determination of detailed positioning, and when results alter towards dynamic activity, fuzzy algorithm (fuzzy categorizer), which is the relationship between speed and ISVM, is used to categorize activity levels into 4 stages. Also, the ISVM is calculated with the instrumented acceleration speed on the running machine according to various speeds and its relationship with kinetic energy goes through correlation analysis. With the evaluation of the proposed system, the accuracy level stands at 100% at a static formation and also a 96.79% accuracy with kinetic energy and we can easily determine the energy consumption through the relationship between ISVM and kinetic energy.

This study investigated the key factors affecting online relational intimacy in the context of SNS. Based on the use and gratification theory, self-presentation, relationship formation and information searching were identified as the main needs of SNS usage. These needs were expected to influence online relational intimacy through user satisfaction, subjective well-being, and disclosing information behaviors. The theoretical framework was validated by a longitudinal method. Hypotheses were tested by using the partial least squares to data from 199 Facebook users. Self-presentation and information searching had a significant impact on both user satisfaction and subjective well-being. However, relationship formation did not significantly affect both user satisfaction and subjective well-being. User satisfaction had a significant direct effect only on online relational intimacy. Subjective well-beings played a significant role in enhancing both disclosing information behaviors and online relational intimacy. Finally, it has been found that disclosing information behaviors are a key factor in enhancing online relational intimacy. The results of this study are expected to provide academic and practical implications for the key antecedents of online relational intimacy.

The purpose of this study is to investigate how to strengthen the formation of relationship competence through the lesson in the housing of the 2015 revised Technology Home Economics curriculum. In order to achieve this goal, we analyzed curriculum documents, achievement standards of curriculum, achievement standards of assessment, and assessment standards of the 2015 revised Technology Home Economics curriculum. Then, we analyzed whether or not the curriculum could be truly reflected in the school site by comparing and analyzing verbs of the assessment standards and curriculum content system. In addition, we suggested the plan to ensure that 2015 revised curriculum can be implemented well by proposing a method of teaching-learning and assessment standards to cultivate the formation of relationship competence among the housing lessons. The results of the study are as follows. First, the 2015 revised Technology Home Economics curriculum are categorized into three subject competences according to the content, but eventually show the content is not mutually exclusive with the three subject competences. It can be said to demonstrate the characteristics of human ability development, that is, one learning can't be related only to one competency. Second, it is difficult to reflect the assessing subject competencies system in school education, where evaluation is carried out based on the assessment standards. This is because the skills of the 2015 revised curriculum documents are partially reflected in the assessment standards. Therefore, this study shows that teachers need to cultivate various subject competencies. In order to overcome the fundamental limitations of the competency-centered curriculum, it is necessary to retrain the teachers as well as to improve teaching and learning methods for operating the curriculum.

The purpose of this study is to find the implications of Christian education on the relationship between the formation of faith and digital literacy in the Korean society, which is rapidly changing within the fourth Industrial Revolution today through critical conversations on educational contexts. Over the past decade, Korean society has lived in an era of rapid and radical change more than any other time through a new way of life called the Fourth Industrial Revolution. The Korean church is also facing the reality that it must fulfill its urgent mission to deliver the unchanging truth in an ever-changing era. With this in mind, this study (1) identifies digital literacy as an essential competency requested in the era of the fourth industrial revolution by examining the relationship with congregation's life as well as its definition and contents, (2) discovers educational rationale for the relationship between faith formation and digital literacy by applying educational context of Christian education with attention to the educational efficiency of digital literacy, and (3) finds educational implications of digital literacy by re-conceptualizing the contents, context, role of teachers and students, and evaluation in the context of Christian education. I hope that this study will help Christian education serve for the spread of the Gospel of Christ and the realization of the kingdom of God on this earth through digital media in the future more time-responsively and mission-practically.

This study was performed to evaluate the effect of membrane exposure on new bone formation when guided bone regeneration with perforated titanium membrane on atrophic alveolar ridge. The present study attempted to establish a GBR model for four adult beagle dog premolar. Intra-marrow penetration defects were created on the alveolar ridge(twelve weeks after extraction) on the mandibular premolar teeth in the beagle dogs. Space providing perforated titanium membrane with various graft material were implanted to provide for GBR. The graft material were demineralized bovine bone(DBB), Irradiated cancellous bone(ICB) and demineralized human bone powder(DFDB). The gingival flap were advanced to cover the membranes and sutured. Seven sites experienced wound failure within 2-3weeks postsurgery resulting in membrane exposure. The animals were euthanized at 4 weeks postsurgery for histologic and histometric analysis. The results of this study were as follows: 1. There was little new bone formation at 4 weeks postsurgery. irrespectively of membrane exposure. 2. There was significant relationship between membrane exposure and bone graft resorption(P<0.05), but no relation between membrane exposure and infiltrated connective tissue. 3. There was much bone graft resorption on DFDB than ICB and DBB. 4. The less exposure was on the perforated titanium membrane, the more dense infiltrated connective tissue was filled under the membrane when grafted with ICB and DBB. but there was no relationship between the rate of membrane exposure and the percentage of infiltrated connective tissue area and no relationship between the percentage of the area in the infiltrated connective tissue and in the residual bone graft. Within the above results, bone formation may be inhibited when membrane was exposed and ICB and DBB were more effective than DFDB as a bone graft material when guided bone regeneration.

Trimethyltin (TMT) induced lesions in the rat hippocampal formation was reviewed. Adult rats were treated with a single dose of 6.0 mg TMT/kg b.w. and were sacrificed between 3-60 days following exposure. On the hippocampal formation, the granule cells of fascia dentata showed early changes which subsided considerably at a later time when the destruction of the pyramidal neurons of the Ammon's horn became increasingly pronounced with time, leading to severe destruction of the structure. It is interesting to note that there was an inverse relationship of pathological involvement between the f.d. granule cells and the Ammon's horn neurons; i.e., when there was a large sparing of the granule cells. there was an extensive damage to the Ammon's horn and vice versa. This inverse relationship was also true between the $CA_3$neurons and the $CA_{1,2}$neurons in the Ammon's horn. Progressive zinc loss, as demonstrated by Timm's method, on the Mossy fibers was also observed. Similar Mossy fiber zinc depletion has been demonstrated in electrical stimulatory excitation condition of the perforant path to the hippocampus. Depletion of corticosterone, an inhibitor to the hippocampal neurons, by means of adrenalectomy will exaggerate the TMT induced hippocampal lesion. Neonatal study revealed that a unique degenerative pattern of the Ammon's horn could be established in accordance with exposure to TMT at specific maturation periods of the fippocampal formation: increasing destruction of the Ammon's horn with increasing synaptogenesis between the f.d. granule cells and the Ammon's horn neurons. Thus it is apparent that the damage of the Ammon's horn, upon exposure to TMT, may depend on the integrity and functional state of the f.d. granule cells. A hyperexcitory scheme and mechanism as the toxicity basis of TMT in the hippocampal formation is proposed and discussed.
