다양한 방송 통신 인프라 확대와 이동형 미디어 단말의 급속한 증가를 통하여 멀티미디어 컨텐츠가 대중화 되었고, 유비쿼터스 시대로의 급속한 전환은 방송 통신 미디어 서비스 산업의 컨버전스화를 가속시키고 있다. 최근 방송 통신 네트워크를 연계하는 홈 네트워크의 보급과 방송 통신미디어를 통합하는 미디어 정보기기의 확산으로 가정 내외에서 방송과 통신 미디어 산업의 경계가 무너지고 있기 때문에 향후 미디어 서비스 산업의 발전은 사용자 입장에서 다양한 미디어 기기를 통해서 언제 어디서라도 원하는 미디어 컨텐츠를 서비스 받을 수 있는 컨텐츠 접의 용이성이 확보되어야 한다. 하지만, 지금까지의 미디어 서비스는 방송 컨텐츠, 인터넷 미디어 컨텐츠 그리고 정보기기용 컨텐츠 통의 미디어들이 서로 다른 미디어 포맷, 전송 그리고 서비스 방식 측면에서 상호 호환성을 확보하지 못하고 있다. 따라서, 방송 통신 미디어 컨텐츠의 호환성, 미디어 컨텐츠의 접근 용이성, 미디인 컨텐츠 분배의 적응성 및 안전성 등을 제공할 수 있는 미디어 서비스 기술의 개발이 절실히 요구되고 있다. 이에, 본 논문에서는 다양한 환경에서의 멀티미디어 서비스에 대한 정보를 메타데이터를 이용하여 데이터베이스화하고, SOAP을 이용한 멀티미디어 서비스 정보의 등록, 리스트 검색 및 상세 정보 검색이 가능한 멀티미디어 서비스 레지스트리를 설계하고 구현하였다.

인터넷은 처음에는 단순히 오프라인에서 유통되는 실물 상품의 흐름을 중개해주는 역할을 해왔으나 인터넷을 통한 실물상품의 중개는 아날로그 상태의 상품들이 인터넷이라는 거간꾼의 중개작용을 통한 전자상거래 형태로 정착되었다. 이러한 실물 상품 유통의 중개자였던 인터넷은 실물 상품들이 디지털화 됨으로써 컨텐츠들의 유통을 위한 통로이면서 동시에 그 자체로서 메시지가 되어버린 하나의 매체로 전환하게 되었다. 그러나, 인터넷을 통해 디지털 컨텐츠들이 쉽고 간편하게 원본과 똑같은 품질로 복제할 수 있을 뿐만 아니라 상상을 초월하는 빠른 속도로 이동이 가능하여 사용자들이 불법으로 얼마든지 이용할 수 있다는 것이다. 현재 국내, 국외에서 이러한 문제를 해결하기 위해 제안한 기술 디지털 컨텐츠들을 보호하고 관리할 수 있도록 하는 DRM(Digital Rights Management)이라는 시스템이 계속적으로 개발되고 있다[1]. 디지털 컨텐츠를 보호하고 저작권을 관리하는 시스템인 DRM 에는 크게 세 가지의 기본 시스템(Publisher, Customer, DRM Server System)이 있다. 본 논문에서는 컨텐츠를 등록하고 저작권자가 그 컨텐츠를 관리하는 DRM Publisher System을 키 알고리즘을 이용하여 설계한다.

A Penicillium strain which produces $eta$-galactosidase with high transgalactosylation activity, was isolated from soil and registered as Penicillium sp, KFCC 10888. When $eta$-galactosidase from Penicillium sp. KFCC 10855 reacted with 40% lactose, transgalactosylation ratio reached up to 70% at the 73% conversion of initial lactose. The biosynthesis of the enzyme in Penicillium sp. KFCC 10888 was not induced by lactose. The soybean meal was an effective component of the culture medium. The optimum pH and temperature for transgalactosylation were 4.0 and 55$^{\circ}C$, respectively. The production of galactooligosaccharides was in proportion to the initial lactose concentration. When the enzyme reacted with 40% lactose (pH 4.0) at 55$^{\circ}C$, the concentration of galactooligosaccharides increased up to 40% of total solid concentration.

A positioning based service uses one's position information with GPS. This application also use the position based characters and change the smart phone to the vibration mode at the registered position. If the user register some places to be vibrated in the smart phone, the smart phone will be automatically changed to the vibration mode as the registered position is same with the position of GPS in the smart phone. If the smart phone is being leaving some distance from the position, the phone will be released from the vibration mode. Therefore, this paper propose aims for intelligent smart phone.

Nomenclatural code for fungi was dramatically modified in the 18th International Botanical Congress (IBC) held in Melbourne, Australia in July 2011. Its name was changed into International Code of Nomenclature for Algae, Fungi and Plants (ICN), which was formerly called as International Code of Botanical Nomenclature (ICBN) of the Vienna Code of 2005. The most important change for fungi is abandoning dual nomenclature and introducing one fungus/one name system (2013. 1). Since more than 10,000 species of fungal names should be renamed based on this new classification system (one fungus/one name system), it is challenging to both mycologists and taxonomic users such as plant pathologists and food scientists. Here, we introduced background, progress and future plan for its transition into one fungus/one name system. The new code is allowing electronic-only publication of names of new taxa (2102. 1) and the requirement for a Latin validating diagnosis was changed to allow either English or Latin for the publication of a new name (2011. 1). Furthermore, pre-publication deposit of key nomenclatural information in a recognized repository is mandatory in ICN (2013. 1). The aims of this manuscript are to introduce new code of fungal nomenclature and recent trends in one fungus/one name system to Korean mycological society.

The purpose of this study is to analysis of the policy and problems of the capital gain tax. So this study identified the problems in the tax system and the method, suggested some ideas that can be useful for reforming the current capital gain tax system. The followings are the concise of some ideas. First, government should adopt the housing market stabilization policy in the long-term period, not in the short-term period which depend on the financial market and the part of home supply. Second, determining the capital gains tax should be transferred to actual market prices system rather than based on the standard assessed prices by government through the nations. By doing so, the desired principles of taxation come true such as principle of taxation on economic substance, principle of taxation on solid foundation and principle of taxation on tax paying ability. Third, transaction taxes should be minimized in the aborting the property speculations and the stabilizing the actual market prices. Fourth, the system of non tax to the owners of 'one family, one house' should be excluded to the tune of principle of tax equity. By doing so, tax payers could be induced to pay taxes on a timely basis not commit to wrong doings. In conclusion, anti-speculation policy should be progressed in such a comprehensive and sustained way as to wipe out the psychology of expectation about the transfer gain's incomes.

This study suggested the methods of record management for the heads of local government, which would be the most valuable among local records. In order to conduct a systematic record management for the heads of local government, this study suggested the methods of establishing a record management system regarding regulation arrangement, production registration, preservation, utilization and services. First of all, in order to estimate the record category of the heads of local government, the study examined the duties of the offices of the deputy heads of local government, secretary's offices and information offices, which have been subsidiary & assistance branches in charge of producing the record. In addition, it investigated the present conditions of record management for the heads of local government through the interviews with secretary offices and information offices belonging to 16 cities and provinces and the claims for information disclosure and found out the following problems. They included incomplete record production, non-registration of produced records, abolition of records and taking them out of designated places with due notice, record preservation period regardless of the term of the heads of local government, varied preservation period for the records of the heads of local government by local self-government, short preservation period of primary records and non-management of home pages after the term of the heads of local government. To solve such problems, the study suggested the regulation arrangement for record management and a record management system. The regulation arrangement could be obtained through the establishment of the administrative organization setup condolence etiquette enforcement regulation and the recorders in local government and the revision of operation rules and through the revision of the reference plan for operation rules enactment of recorders from National Archives of Korea. As for the record management system, the study suggested the establishment of production, registration and preservation system of records for the heads of local government and the utilization and services of their records. In order to produce and register the records, the unit assignments should be founded by department in charge of the duties related to the records of the heads of local government on record management criteria, thus letting the staff surely produce and register the records. In terms of utilization and services of the records, the study suggested the use of websites and drawing up the record list, through which each record viewer would be able to figure out which records have been managed through the list services and which services could be given to the residents, thus letting the residents and the heads of local government who finished their term of duties use the records.

The SF-36 is the most common instrument to check the quality of life for dialysis patients with chronic renal failure. However, there were too much burden for them to answer 36 items of it. So we purposed to develop the RFQoL-K reduced type of the SF-36. Participants who had newly registered for dialysis were enrolled in 29 medical centers during 45months from 2009. We developed the RFQoL-K through 355 people who applied the SF-36 at 3 and 12 months after registration and then checked it's internal validity. External validity about it was checked via 411 people who answered only one time survey after registration. In conclusion, the RFQoL-K had total 14 items which was consisted of 8 items on physical factors and 6 items on mental factors from the SF-36. The RFQoL-K summary scores explained 91-93% of the SF-36 summary scores. The RFQoL-K was well reflected SF-36 because the correlation and the internal consistency between two tools were very high 0.96 to 0.98 and 0.96 to 0.98 respectively.

The objective of this study was to analyze 'Forestland Classification System' in Korea and to develop a strategy for its improvement. A survey was conducted in this study based on the Delphi technique, one of the interactive survey method relying on a panel of experts. The result indicated that the existing 'Forestland Classification System' was initiated for reasonable management of forestland, but now it turned into one of the most strict management restrictions. To improve forestland management in Korea, it was suggested to adopt 'Forest Function System' in this study. Moreover, to avoid indiscreet landuse conversion that might be occurred by substituting the 'Forest Function System' for the 'Forestland Classification System', it was suggested to adopt 'Forestland Conversion Propriety Assessment System'. In fact, landuse conversion has been regulated by the 'Environmental Impact Assessment System', but this system appeared inadequate to be applied to the forested area. Illegal acts for having permission of landuse conversion for reserved forests was another big issue in the forestland management. For example, alteration of the reserved status of forests or partition into patches smaller than the size limit has been attempted. Thus in this study, it was strongly recommended to take sanction against such illegal acts. In order to enhance the efficiency of forestland management, it was also suggested to integrate administrative agencies related to the landuse conversion or to take over the charge to local governments.
