  • Proxy Mobile IPv6(PMIPv6) is a network-based mobility management protocol and it does not require mobile node's involving in mobility management. In PMIPv6, the Mobile Access Gateway (MAG) incurs a high signaling cost to update the location of a mobile node to the remote Local Mobility Anchor (LMA) if it moves frequently. It may cause excessive signaling traffic and increase a high traffic load on LMA. Therefore, we propose a new mobility management scheme in proxy mobile IPv6 networks with dynamic paging support. To minimize signaling overhead, in our proposal, the size of the paging area is determined dynamically according the changes of mobility and traffic patterns of the mobile node. An analytic model is applied to determine the optimal size of the paging area. The cost analysis using fluid flow model presented in this paper shows that our proposal can achieve performance superior that of PMIPv6 scheme.

  • Essential hypertension is a typical chronic disease requiring adequate and continuous management. And many studies supported that self-care was the essential factor to promote the wellbeing. The purpose of this study is to identify and understand the behavior patterns of self-care in hypertensives. As a research method, 35 Q-statements were collected through Individual interviews and review of the related literatures. 21 subjects were interviewed and the data were analyzed by the PC QUANL program with principal component analysis. There were 6 different self-care types classified as follows 1) Type 1 was the self-oriented control type, monitoring the blood pressure and taking the low salt diet. But they didn't take the anti -hypertensive drug and visit the health agency regularly. 2) Type 2 was the stress-control type. Their main activities were meditation to relieve the stress and communication with family. 3) Type 3 was called daily-life control type. This type tried to make their mind comfort and think positively. They also preferred walking and exercise regularly. 4) Type 4 was the medical-oriented control type, taking the anti-hypertensive drug, visiting the medical personnel and following the medical regimens. 5) Type 5 was the medication-oriented type. They only took the anti -hypertensive drug regularly and didn't any other self-care like as monitoring the blood pressure, taking the low salt diet and exercise. 6) Type 6 was called non-medication control type. This type had no medication, but tried to visit the health agency and health personnel. From the above results, it can be concluded that the self-care types were very various and self-care education have to provide individually according to the characteristics of self-care type. Another repeated study can be recommended to improve the nursing intervention the self-care behavior in chronic patient like as diabetics or rheumatoid arthritis.

  • This study explores reasonable alternatives to internet interconnection policy. Due to the development of information and communication technology, patterns of the Internet usage are changing rapidly, including increase of video streaming services. For this reason, there is a lively discussion of the Internet interconnection policy, which integrates various Internet service operators into one ecosystem. We conducted an Analytic Hierarchy Process(AHP) analysis with 16 experts in government/public, and academic sectors, and alternative selection criteria and their corresponding alternatives and detailed tasks were evaluated. According to the results, the most important alternative selection criteria was a "fair charge against foreign service operators", and the most desirable alternative was "partial revise". Moreover, the experts responded that "reassessment of the principle of the charge" is the most urgent task to improve the Internet interconnection policy.

  • Fashion, a means of communication, is the symbol conveying the social information and the individual identity. The opulence of material and the development of civilization make the sign of fashion variable and individual; especially, The importance of hair style among the today's sign of fashion, as a determinant element in judging each person's look is emphasized. Kitsch, based on the variety and the individuality is the manner of art in diverse hobbies. In addition, it enlarges the sphere of modern an, creates new open aesthetic world. Therefore, we need to understand the symbol of Kitsch aestetic represented in hair style, which is meaningful. The method of this study is quality analysis by means of semiology, aesthetics, Fashion artical, magazine, atc. To support this statement, we will study the form, a primary symbol, and the ideology, a secondly one in $\ulcorner$Mythologies$\lrcorner$ of Roland Bartes(1972). Then by means of the form and the ideology, we will try to recognize the myth, an essential symbol. The result of this study is following like these three points. First, the Kitsch patterns of representation in hair style use the accumulation by an excessive ornamentation; the inappropriateness by the lack of form, the disagreement, the unbalance, and the nonfunctional form; and finally, the amusement by the reconstruction, the exotic, and the satire. The above three is true to the Barthes's primary symbol-the form. Second, the anti-traditionality(including the lack of form, the disagreement, and the unbalance), the homesickness(including the reconstruction and the exotic), and the eclecticism(including the parody and the mixed imitation) are created as the ideology of the liberal artistic notion, different from the past outlooks on aesthetic. This is true to the Barthes's secondly symbol-the ideology. Third, the form and the ideology enable us to express our own thoughts and to recover the humanity, which is the primary purpose of Kitsch aesthetic. The Kitsch hair style, as we witness, does lead the varied and liberal aesthetic world, create its accessible value, and place the art of hair style in a higher status.

  • In this study, change trends and specific times for change in body size were sought to be identified by using manual measurements for Korean adult women at 20 to 89 of age, along with examinations of change trends and specific times of change in body shape based on body index values. The examinations of means, deviations, and variation coefficients revealed that there was a tendency of most height related measures to decrease. In addition, combined with decrease in height, growth in weight led to increased BMI, thus resulting in increase in measures of circumference, thickness, and breadth in the torso area. The BMI trends showed that with increasing age, BMI increased, reaching the peak between the ages of 55 and 59 and then decreasing from 64 of age, with the steepest increase in BMI at ages from 50 to 54. The examination of differences in the body flatness ratio for different parts of body found that with increasing age the ratio decreased, indicating a tendency for gradual change to round body shapes. The analysis of 3D body shape found that there were more back-bends and lowered shoulder levels with age, accompanied with a tendency for more bended legs and more inclined-forward necks. The key trends in changes in body measurements by age and detailed estimates of 3D standard body shape drawn out from this study are expected to significantly contribute to establishing a basic database for generating patterns reflecting age features of Korean adult females.

  • To understand the response of cancer cells to anticancer drugs at the gene expression level, we examined the gene expression changes in response to five anticancer drugs, 5-fluorouracil, cytarabine, cisplatin, paclitaxel, and cytochalasin D in NCI-H460 human lung cancer cells. Of the five drugs, 5-fluorouracil had the most distinctive gene expression signature. By clustering genes whose expression changed significantly, we identified three clusters with unique gene expression patterns. The first cluster reflected the up-regulation of gene expression by cisplatin, and included genes involved in cell death and DNA repair. The second cluster pointed to a general reduction of gene expression by most of the anticancer drugs tested. A number of genes in this cluster are involved in signal transduction that is important for communication between cells and reception of extracellular signals. The last cluster represented reduced gene expression in response to 5-fluorouracil, the genes involved being implicated in DNA metabolism, the cell cycle, and RNA processing. Since the gene expression signature of 5-fluorouracil was unique, we investigated it in more detail. Significance analysis of microarray data (SAM) identified 808 genes whose expression was significantly altered by 5-fluorouracil. Among the up-regulated genes, those affecting apoptosis were the most noteworthy. The down-regulated genes were mainly associated with transcription-and translation-related processes which are known targets of 5-fluorouracil. These results suggest that the gene expression signature of an anticancer drug is closely related to its physiological action and the response of caner cells.

  • Supply of a smart device has been made with the development of communication networks and growing desire of people to improve the quality of life, the service industry about it have been made with smart devices. Among them, there are various services that can help people change their behavior to healthy life. But it does not have a large impact on the behavior change of performer because its been developed as a general process. Therefore in this study examine development situation about current behavior change applications through application markets. Development current situation can be separated by process to two patterns. As a result we propose behavioral change model that includes integrated change model that one of the behavior theory model, accomplish the goal process of goal setting theory and habit formation phase for automate the changes. Also, we provide appropriate service according to the model that leads motivation, sustainability of the action and positive behavior change to performer. We can expect in many aspects such as ability and motivation than existing service.

  • Purpose: This study was intended to integrate the evidence of home care service intervention for mothers and children in vulnerable groups through an integrative literature review. Methods: We searched the MEDLINE (PubMED), EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, DBpia databases. The quality of the articles was assessed by one doctoral researcher and verified by one professor of community health nursing who had participated in the systematic review of literature. A framework was developed to identify the intervention patterns in the selected papers and categorize various elements. The extracted intervention elements were grouped into potential themes, which were verified by assessors on whether they clearly reflected the interventions in the papers. Results: Among 878 searched papers, we selected 16 papers after excluding literature that does not satisfy the selection criteria and quality evaluation. The intervention elements of 16 selected papers were categorized into six themes. The extracted intervention elements were divided into the themes of Patient-specific/Situation-specific care planning and intervention, Emphasis on self care competency, Intense home visit by developmental milestone, Reinforcing and modeling mother-child attachment, Communication and interaction across the intervention, Linkage with community resource and multidisciplinary approach. Conclusion: As a result of the analysis of proper interventions of home care services for mothers and children in vulnerable groups, it was found that it is necessary to consider indispensable intervention elements that can standardize the quality of home care services, and conduct studies on developing intervention programs based on the elements.
