This study was aimed to apply thermochromic and photochromic pigments to coating color and to develop a speciality functional coated layer. Two special pigments were added to a conventional coating color. The effects of the special pigments on coating color properties such as water rerention, low-shear viscosity were evaluated. Also the color changes of coated paper was observed under various circumstances. The results showed that the special pigments didn't influence the coating color properties. The coated paper with the special pigments showed four different colors, under various circumstances, implying that thermochromic and photochromic pigments can be used to produce a security paper.

Troublesome problems are being caused by hallucinogenic drugs which come not only from illegal narcotics but also from unprohibited general drug-kinds such as cough-remedy agents of textromerupan, namely, Lamina, Rubi-king and the likes. Abuse and misuse of narcotics permeated into and threatens mental health of socially-known peoples, actor, actress, talents and businessmen as well. This study especially dealt with problems related with Mesampetamin, Rurajaepam, Texstrometropan and Karisofrodol which affects mental behaviour, and considered counter-measures through analysis and developed appropriate system of goods circulation for guidance to be complied by the medicine professionalists. The guidance sought here is recommended to the government ministries for further enforcement of crack-down of the drug crimes. Arquesa in method is recommend as a method of identifying behaviors and facial expressions of abusers and misusers of narcotics at the spot in place. This study is directed to curtailing hallucinogenic drugs use for absolute preventive security by detecting out black dealers of narcotics supplying to the abusers and misusers. There is a need of special education program to cut off the flow of narcotics or drugs crimes into official security force as well as private security personnel. This study introduced a priority and emphasis of real augmentation to theory and practice of the modern scientific security which can protect the mental health of the guarded persons as well especially in the light of security safety curriculum at the school.

This study describes the retention of title under UCC. UCC ${\S}$ 2-401 prescribes that any retention or reservation by the seller of the title (property) in goods shipped or delivered to the buyer is limited in effect to a reservation of a security interest. It means that the retention of title generates a security interest in the same way like a charge. To be effective, a security interest must be attached or perfected. Once attachment occurs, a security interest is enforceable against the buyer. Once a security interest is perfected, a security interest is enforceable against third parties. Under UCC, a simple retention of title clause is valid as long as it is incorporated into the contract of sale. If the seller acquires a perfected security interest, he as a secured party can enjoy a priority against other creditors. But if a security interest is not perfected but PMSI is afforded, the seller has a special priority. Secondly, under UCC ${\S}$ 9-335 and 9-336, if a security interest under an enlarged retention of title clause is perfected, the seller as the secured party has a valid security interest in the product or mass into which his goods have been mixed or commingled. But in terms of assession of goods, as the seller has a security interest only in his goods, if the seller wants to enlarge his security interest in the whole, a security agreement should cover its intention. Thirdly, under UCC ${\S}$ 9-315, a security interest in proceeds of subsale of goods supplied by the seller is a perfected security interest if the security interest in the original collateral was perfected. But if the proceeds are cash proceeds, it should be identifiable from other funds of the buyer.

본 논문에서는 경찰청에서 제공하는 2019년 민간경비업체와 민간경비원의 현황을 통해서 민간경비의 다양한 해석과 사각으로 이론적 기반을 마련하는 것을 목적으로 한다. 민간경비업체와 경비원 수는 총 5356개와 16만 3177명으로 나타났다. 현황으로 살펴본 민간경비업의 특징은 크게 4가지가 나타났다. 첫 번째 민간경비업체 수와 경비원의 수가 수도권으로 집중되었다. 기계경비원을 제외하고 53%~89%가 수도권(서울·경기·인천)에 집중되었다. 두 번째, 시설경비에 대한 집중이다. 시설경비가 민간경비업체와 경비원 수에 차지하는 비율은 각각 83%와 86%를 차지함으로써 경비업법에 의한 구분이 아닌 경비원은 곧 시설경비원을 뜻하는 것처럼 느껴지게 되었다. 세 번째, 비정상적인 신변보호 업체 수와 경비원 수이다. 2019년 기준으로 신변보호 업체의 수보다 신변보호원이 없는 상황이 발생하고 있고, 이는 허가만 유지, 시설경비업무와 경계모호, 신고 누락, 자체경비 전환으로 인한 것으로 보인다. 네 번째, 특수경비업의 특수성이다. 국가중요시설에서 일하는 특수경비원은 국가의 정책에 따라서 한국공항공사의 한공보안파트너스, 인천공항공사의 인천공항경비를 자회사로 하고 정규직 전환을 진행 중에 있기 때문에 특수경비업체 수와 경비원 수의 변화는 불가피한 것으로 보인다.

Cloud computing is cost-effective in terms of system configuration and maintenance and does not require special IT skills for management. Also, cloud computing provides an access control setting where SSO is adopted to secure user convenience and availability. As the SSO user authentication structure of cloud computing is exposed to quite a few external security threats in wire/wireless network integrated service environment, researchers explore technologies drawing on distributed SSO agents. Yet, although the cloud computing access control using the distributed SSO agents enhances security, it impacts on the availability of services. That is, if any single agent responsible for providing the authentication information fails to offer normal services, the cloud computing services become unavailable. To rectify the environment compromising the availability of cloud computing services, and to protect resources, the current paper proposes a security policy that controls the authority to access the resources for cloud computing services by applying the authentication policy of user authentication agents. The proposed system with its policy of the authority to access the resources ensures seamless and secure cloud computing services for users.

Attempts have also been made to locate security in the so-called 'policingdivision of labour' In order to understand this, it is necessary to identify some of the links which exist between public police organizations and the private security sector. Such links can be divided into six types : 1) Interpersonal links, 2) Joint operations, 3) Exchange of services, 4) Granting of special powers, 5) Public bodies hiring private personnel, 6) New organizational. Van Reenen provides a useful outline of the different dimensions of future Glibalization of policing. Developments, he suggests, are likely to proceed in four directions : 1) Co-operation : at this level, the nature and powers of national police systems are not required to change, co-operation occurring between self-standing forces. 2) Horizontal integration : this arises when officers obtain authority to operate in another country, or where government officials from one country get authority over the police in another country. 3) Vertical integration : this exists when a police organization is created which can operate within the area of the EC as a whole. 4) Competition : the internationalization of policing in Europe presents itself, more and more, as a market in which different policing systems trade their products.

Partial transactions which use computer networks are formed in the cyberspace due to rapid progress of communication and computer technology. Electronic business transactions have security problems according to the special quality of opening networks, while it can be approached easily by anyone without being tied to time and places through Internets. To revitalize the electronic business transactions, security technology which can establish its security and trust is the prior task and both safe information communication and better information security service offer are essential factors. The method to exchange information through Internets must be made after confirming one another's exact connection in the mutual identity certification to prevent a lot of threat which can occur in the use of password techniques. To satisfy these electronic business transactions, we intend to increase understanding of authentication algorithm provided with authentication function of messages and users as well to plan safety and trust of business information and contents in the electronic business transactions.
