As a large portal sites are beginning to replace the function of the mass media, new risks began to raise. It remained without being deleted that data written to the internet was a serious privacy problem occurs. The sensitive information was inferred based on the personal data recorded in the past and also another personal information leakage itself. Witch-hunt through the personally identifiable rob has emerged as a serious social problem and damage to the parties not be able to live a normal life. In this paper, we propose the study on the need for a 'right to be forgotten' to delete the personal information relating to on-line through international case studies and activation measures. At the same time, we proposed improvement measures, such as encryption management, ownership inheritance, and blind treatment.

The increase of female employees tends to change the traditional division of the roles of members in the family, and as a result it changes the idea of family relation and the extent of how housewives with job feel happy toward their marriage. Therefore, it may be very significant to study what attitude woman job holders as housewives have toward their family, especially parents-in-law. In this paper the writer has sampled as an exemplary group woman teachers who teach home economics in high schools in Seoul, and investigated what opinion they have toward the problem of living together under the same roof with their parents-in-laws and otherwise of financing them in an older age. This analysis is based upon 130 questionnaires collected as proper data out of 138. The conclusion made from the analysis is as follows : (1) as regards the living together under the same roof if necessary in the future, one-fifth of the group approves in affirmative terms ; (2) but when parents-in-law become older, about half of the teachers wish to live with them in the same home and except the indefinite few, one-third of them taken the negative position ; (3) finally, the great majority (84%) regard as their duty the financial support in any case when parents-in-law become older, and only five per cent answer in negative. This analysis leads to the further conclusion that the idea of family relations cherished by high school teachers of home economics is not yet far off the traditional relationship with the intention of gradual improvement, but on the other it still sticks to the traditional line without too much impairing it.

The information security industry market is sluggish despite high expectation for its growth, and thus policies are required to define the causes and to address these issues. The policy formulation requires various historical market and human resource data for analyzing the industry, which cannot be guaranteed secured. This study executed face-to-face in-depth interviews with the frontline businesses in order to gather live opinions and to analyze industry's value chain, problems, and difficulties with a view to defining policy tasks for the development of the industry. The findings of the study revealed the current technical level of the information security industry, the frontline difficulty, and industrial ecosystem status. Based on these findings, the industry revitalization policy was devised and proposed. Objectives of the policy included the fostering of capacity to conceptualize, plan, and design industrial strategies based on the analysis of the industry's value chain and ecosystem, the expansion of the industry's value-added through the enhanced securing and management of the Intellectual Property Rights (IPR), and the nurturing of the security Human Resources (HR) in line with the industrial demand.

Bridges are ones of fundamental facilities for roads which become social overhead capital facilities and they are designed to get safety in their life cycles. However as time passes, bridge can be damaged by changes of external force and traffic environments. Therefore, a bridge should be repaired and maintained for extending its life cycle. The working load on a bridge is one of the most important factors for safety, it should be calculated accurately. The most important load among working loads is live load by a vehicle. Thus, the travel characteristics and weight of vehicle can be useful for bridge maintenance if they were estimated with high reliability. In this study, a B-WIM system in which the bridge is used for a scale have been developed for measuring the vehicle loads without the vehicle stop. The vehicle loads can be estimated by the developed B-WIM system with the reaction responses from the supporting points. The algorithm of developed B-WIM system have been verified by numerical analysis.

In this study, an immunoactivity of panaxtriol ginsenosides Re and Rg1 against infection due to Candida albicans was investigated. The ginsenosides were extracted from Red Ginseng with 85% ethanol and heat-treatment and were analyzed by HPLC on water-acetonitrile as a mobile phase. The HPLC analysis revealed that the extract contained ginsenosides Re and Rg1, which were eluted as a combined peak. By agar diffusion susceptibility, the mixture of Re and Rg1 had no growth-inhibitory activity on C. albicans yeast cells. However, in animal tests BALB/c mice given the mixture of Re and Rg1 intraperitoneally (Lp.) before intravenous (Lv.) infection with live C. albicans yeast cells had longer mean survival times (MST) than MST of control mice groups that received only buffer solution instead of Re and Rg1. In experiments 60% of the ginsenosides-treated mice survived the entire duration of the 50-day observation. The Re and Rg1 mixture induced production of nitric oxide when interacted with RAW 264.7 macrophage cell line. In addition, the mixture caused morphological change of the macrophages. These data indicate that immunostimulation by the Re and Rg1 may be responsible for the protection of mice against disseminated candidiasis.

In the Republic of Korea, there's been a culture called 'Hyo' since Koryo Dynasty and this word represents the meaning of paying utmost respects to one's own parents and ancestors whether they are alive or have passed. However, nowadays, most of people live away from their family gravesites so that they do not and cannot take care of them except on the special holidays. For this reason, people could not respond promptly to the incidents occurred at the sites as they receive notifications much later dates most of the time. Thus, in this paper, we propose a low-cost gravesite monitoring system which the users can immediately respond to the disastrous events after being informed of current situations through PLC without delay. For the performance evaluation, the lab and test bed experiments were performed on an actual ship using 200Mbps and 500Mbps products instead of performing an on-site experiment after the system has actually been constructed. The Mountain Region PLC was installed on the power lines and the result showed successful 36.14Mbps communication. Therefore, we expect that this study will contribute in time and cost reduction while constructing the internet infrastructures in mountain regions or building the Smart-graves, tumulus, and charnel houses.

Carchesium polypinum and Vorticella campanula were collected in freshwater ponds and reservoirs on Jindo Island and other places in Korea. These two vorticellids are newly recorded in Korea. The two species are described using live and silver impregnated cell observations, morphometry, line drawings, and microphotographs. Characterizations were based on the following diagnostic features: Carchesium polypinum was observed mainly as a funnel to fanshaped colony, basically dichotomous branching pattern, discontinuous spasmoneme, subconical shaped zooid, J shaped macronucleus, ventrally positioned single contractile vacuole, and pellicular striation with 61-80 rows between the peristomial lip and aboral ciliary wreath, and 18-30 rows between the aboral ciliary wreath and scopula. Vorticella campanula was conspicuously characterized by the broadly bulged peristomial lip, wide conical shaped zooid, J or S shaped macronucleus, ventrally positioned single contractile vacuole and pellicular striation with 64-75 rows between the peristomial lip and aboral ciliary wreath, and 27-41 rows between the aboral ciliary wreath and scopula. We provide redescriptions of two well-known vorticellids with detailed drawings and descriptions of oral ciliatures from Jindo Island and other places on the Korean peninsula.

AMR(Automatic Meter Reading) and RC(Remote Control) System have been researched from former several decade for a various power rate system, a efficient power service and rising of personal expenses, etc. But the existing AMR and RC System have disadvantage which are complex and high cost to install an individual communication network of electricity company. This paper proposed a new type of AMR and RC System using PLC with Web. and made components for proposal system. Most customer who live in apartment have an internet cable in the Republic of Korea. Therefore there is no more installation component for communication in proposal system at the apartment, except Web server system and PLC modem. so we made the PLC modem the digital watt-hour meter with a build in PLC modem and the software on server computer for establishing the proposal system.

Because of ocean waves, swell, steering corrections, etc, the hydrophones of a towed array will not live along a straight line. However the degradation of bearing estimation performance occurs when beamforming is carried out on the hydrophone outputs of an acoustic towed array which is not straight. So it is required to estimate the shape of the array for the improved beamformer output. In this paper, an iterative array shape estimation technique is presented, which is based on the use of the least squares polynomial fitting to the data from heading sensors. The estimation error and the influence of deformations on the performance of the conventional beamformer output are investigated. Finally, the suggested method is applied to the real system in order to investigate the applicability.

As art of lamination by plywood got to be generally used, it became a suitable material for expressing live curves that were not able to be expressed on wood furniture made of plank and timber, as well as, openwork deep in curved space, heavy quality of material, and changing contour line-looking wave lines with different process angles. As an alternative, it would be good to build a full scale model, since it would provide practice in form-building and it would also provide a chance to correct the form. Less material can be used and reduce the cutting process by Properly trimming models made of soft formal structure such as Styrofoam Iso-pink and adhesive Styrofoam, and separating the layers and using them on shape cutting of plywood with the same thickness. And by attaching the model veneer that was used in shape cutting of the model and using it as a cutting guide, we can reduce the error of work and successively build the planned form. Since this study is about the need of a full scale model for a laminated wood model and an efficient process, this study concentrates more on process.
