As a very rapid diffusion of internet business in these days, the marketing mix strategies become more important matters. In addition, because of changes in international trade patterns, and an increase of internet users, new marketing strategies are needs. There's not a business in the world that shouldn't feel threatened by the internet, but companies willing to become engaged should find big opportunities. Becoming engaged with the internet, for matters, means understanding the unique nature of the internet market and using that understanding to execute dynamic strategies. This paper is focusing the analysing the difference between the internet marketing and traditional marketing and proposing the new strategical marketing mix. In the traditional marketing environment, 4P(Product, Price, Promotion, Place) is very important, but in the internet business environment 6C(Community, Connection, Commerce, Communication, Customization, Contents) is more important.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Together the reason of subcontract at managing the big business the case which becomes accomplished in objective, about lower the immediacy safety&health problem, subcontractor assigned workers is the actual condition only it could not be deteriorated more in public finance of the supply and enterprise and technical ability insufficiency. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor.

The success of road transportation, in dominating the surface movement of freight, is now threatened by increased traffic congestion, falling average motorway speed and rising in logistics costs, oil price. Due to the necessity for an effective transport system, we need to improve domestic transport infrastructure to reduce logistics cost by shifting to rail system. To analysis the demand characteristics in advance against these hypothetical circumstances, Stated Preference, which is called SP, approaches have been adopted to analysis the shipper's mode choice behaviors as RP(Revealed Preference) approaches are not appropriate. The results also indicate that the most effective policy to divert the freight volume from road to railway is to reduce freight rates for the railway with improved reliability.

Kyoaesamultang(KAT) has been used as an important prescription for various diseases including threatened abortion, associated with pregnancy in traditional medicine. In oder to identify the safety of KAT, this study was designed to determine mutagenicity and hepato-toxicity. In Rec-assay, Bacillus subtills H-17($Rec{^+}$) and M-45($Rec{^-}$) strains were used to clarify the DNA damage property. In Ames test, Salmonella typhimurium TA98 and TA100 were used for mutagenicity testing. In SOS umu test, Salmonella typhimurium TA1535 containing plasmid pSK1002 was used as a tester strain, and the levels of umu operon expression were monitored by measuring the $\beta$-galactosidase activity. From tested results, KAT did not show DNA damage and mutagenicity. On the other hand, hepato-toxicity of KAT to female ICR mice was monitored by the measurements of s-GOT, s-GPT and LDH activities after oral feeding for 15days. KAT showed 34% increase of s-GOT and s-GPT activities, also exhibited 35% increase of LDH activity in mice sera.

Recent extreme weather events and natural disasters are causing rapid aging of the ancient structures with cultural value. It has threatened the safety and management. The construction design documents are not kept for such long time. Even if they are, they seem to be mismatched with the design structures due to corrosive effects. For these reasons, Korea has been facing difficulties in maintenance, reengineering and safety evaluation. In this study, three dimensional point cloud surface of bobsleigh is obtained using 3D LiDAR scanner. The obtained structure is compared with the original design and found to be highly accurate. The study shows the application of reverse engineering technique and its potential use for other civil structures.

디지털기술의 발달로 정보유통 방법이 다양해지고 신속하게 이루어지는 반면 저작권과 관련된 행위가 무분별 하게 발생되고 있어 교육적 사회적 논쟁이 되고 있다. 본 연구에서는 대학도서관을 이용하는 대학생을 대상으로 논쟁의 대상인 불법적 행위 발생 정도를 조사분석하여 문제 해결 및 교육방안을 모색하는데 있다. 우선 저작권에 대한 일반적 개념을 이해하고 저작권침해와 관련하여 실제사례를 조사하고 이중 연구자료로 활용할 수 있다고 판단되는 사례를 선택하여 인식정도를 분석한 결과 불법적 행위라는 사실을 알면서 복제 및 전송 행위가 무분별하게 발생하고 있음이 밝혀졌다.

Purpose: This is a descriptive research that reports incidents of workplace violence among care helpers. Methods: The subjects were 181 care helpers from elderly care facilities and domiciliary elderly welfare centers in Daejeon. Data were collected through self-administered questionnaires from July to November 2011. Subjects were asked to report incidents of violence within the previous six months. Data analysis included one-way ANOVA, and logistic regression analysis. Results: Forty-seven percent of care helpers reported verbal violence, 16% reported being physically threatened, more than 21 % reported sustaining a physical injury with 2% reporting severe physical injuries. Further, 18.8% of the care givers reported being sexually harassed by client. There were differences in reported workplace violence based on service types, service hours and whether there were policies about workplace violence. Conclusion: To prevent workplace violence for carehelpers, it is necessary to make a policy for preventing violence and develop a violence prevention program to meet service characteristics of facility-based and domiciliary care helpers.

When a ship is sailing on the sea, she has the six-degrees of freedom of motion. It means that she meets a lot of dangerous situations. Especially, when the VLCC is travelling in irregular sea, the slamming, the deck-wetness and the propeller racing are occured with the sea state she is on. These are the representative steps that a heave-to and a scudding are used for a ship building , but for a predominance in both. The author intends to clarify this problem theoretically. The methods of statistical calculation are based with the ITTC spectral formulation and with the assumption that the wave height histogram follows the Rayleigh distribution. In this study, the author gives an attention on the relative bow motion to a wave in the irregular sea. It is verified that the relative diplacement at the bow to sea level in the following sea is less than that in the head sea. It is confirmed that, therefore, one have to sail with scudding when he is threatened to heave-to at a rough sea. But he must bear the propeller racing in mind in the cases.

In man-machine communication by speech under the noisy environment, the quality of speech may be degraded severely for the machine to recognize correctly. Especially when the corrupting noise occupies the same band as the speech, the conventional fixed filters cannot filter out the noise effectively. In recent, to resolve such a problem adaptive noise canceller (ANC) is frequently used, which is based upon adaptive filters. The Adaptive recursive filters perform better than adaptive nonrecursive filters due to the added poles, but the stability may be severely threatened. In this paper an ANC system employing the adaptive recursive filter is proposed to enhance the speech corrupted by noise. And the stability of the adaptive recursive filter is guaranteed by employing the adaptive compensator.

The more VoIP service is widely used, the more VoIP spam becomes threatened. Both VoIP spam violates the user's privacy and VoIP spam can cause money trouble. Therefore, it is important to reduce the VoIP spam but it is not easy to adopt some useful techniques to counter e-mail spam due to VoIP characteristics. We propose a technique using VoIP-RBL for countering SIP-based VoIP spam.
