  • 육상기인 오염원의 해양유입의 급속한 증가로 인해 유해성 적조발생이 빈번해졌을 뿐 아니라, 양식기술의 발달과 과밀양식으로 인해 연안역의 자가 오염증가가 가속화되고 있다. 따라서 해양환경 관리와 적절한 해역이용을 위해 과학적인 관리의 필요성이 증가하고 있다. 현행 환경기준은 일본의 해역 수질기준을 준용하여 육상의 배수기준에 희석 비율을 적용시켜 설정하는 공학적인 방식이다. 그리고 해역의 환경특성을 고려하지 않고 일률적인 값을 적용하였다. 유럽연합, 미국, 호주, 캐나다 등의 선진국에서는 이미 20여 년 전부터 종합적인 수질관리대책을 마련하고 있다. 따라서 본 연구에서는 우리나라 해양환경 특성에 적합한 수질평가 기준을 설정하기 위해 해역을 해류, 조석, 탁도 등을 기준으로 다섯 가지의 생태구로 구분하였다. 그리고 국가해양측정망의 관측항목 중에서 부영양화의 원인항목(용존 무기질소(dissolved inorganic nitrogen, DIN), 용존 무기인(dissolved inorganic phosphorus, DIP)과 일차반응항목(클로로필, Secchi depth)과 이차반응항목(저층용존산소포화도, bottom dissolved oxygen saturation)에 해당하는 항목들을 평가항목으로 선정하였다. 용존 무기질소, 용존 무기인과 클로로필의 기준값은 각각의 생태구에서 하천의 유입 영향이 최소인 외양역 정점의 2000년에서 2007년까지의 계절별 평균값 중 최대값으로 하였고, Secchi depth는 계절별 평균값 중 최소값을 선택하였다. 그리고 저층용존산소 포화도는 외양역의 평균값 중 최소포화도 값인 90%를 전체 생태구의 기준값으로 정하였다. 전체연안을 체계적이고 동일한 기준으로 관리하기 위해서 개별 평가항목의 점수로부터 원인항목, 일차반응 항목, 이차반응 항목 순으로 큰 가중치를 부여하는 가중선형합산 방식으로 수질지수를 계산하였다. 2000년부터 2007년까지 모든 정점에서 구한 수질지수의 분포는 최소값인 20과 중앙값이 30에서 빈도수가 높은 쌍봉분포가 나타났다. 따라서 수질지수의 쌍봉분포 앞부분에 해당하는 23이하를 매우좋음(I등급)으로 하였고 최소값+표준편차 이하를 좋음(II등급), 최소값+2표준편차 이하를 보통(III등급), 최소값+3표준편차 이하를 나쁨(IV등급), 그리고 최소값+3표준편차 초과일 때 아주나쁨(V등급)으로 정하였다.

  • The database for the oriental medicine had been existed in documentation in past times and it has been developed to the database type for random accesses in the information society. However, the aspects of the database are not so diversified and the database for the bio herbal material exists in widened type dictionary style. It is a situation that the database which handles the in-depth raw herbal medicines is not sufficient in its quantity and quality. Korean wild grape is a deciduous plant categorized into the Vitaceae and it was found experimentally that it has various medical effects. It is one of the medical materials with higher potentiality of academic study and commercialization recently because it has a bigger possibility to be applied into diverse industrial fields including the medical product for health, food and beauty. We constituted the cooperative system among the Muju cluster business group for Korean mountain wild grapes, Physiology Laboratory in Kyung Hee University Oriental Medicine and Medical Classics Laboratory in Kyung Hee University Oriental Medicine with a view to focusing on such potentiality and a database for Korean wild grapes was made a touchstone for establishing the in-depth database for the single bio medical materials. First of all, the literatures based on the North East Asia in ancient times had been categorized into the classical literature (Korean literature published by government organization, Korean classical literature, Chinese classical literature and classical literature fro Korean and Chinese oriental medicine) and modern literature (Modern literature for oriental medicine, modern literature for domestic and foreign herbal medicine) to cover the eastern and western research records and writings related to Korean wild grapes and the text-mining work has been performed through the cooperation system with the Medical Classics Laboratory in Kyung Hee University Oriental Medicine. First of all, the data for the experiment and theory for Korean wild grape were collected for the Medline database controlled by the Parliament Library of USA to arrange the domestic and foreign theses with topic for Korean wild grapes and the network hyperlink function and down load function were mounted for self-thesis searching function and active view based on the collected data. The thesis searching function provides various auxiliary functions and the searching is available according to the diverse searching/queries such as the name of sub species of Korean wild grape, the logical intersection index for the active ingredients, efficacy and elements. It was constituted for the researchers who design the Korean wild grape study to design of easier experiment. In addition, the data related to the patents for Korean wild grape which were collected from European Patent Office in response to the commercialization possibility and the system available for searching and view was established in the same viewpoint. Perl was used for the query programming and MS-SQL for database establishment and management in the designing of this database. Currently, the data is available for free use and the address is as follows. http://163.180.41.43:8011/index.html

  • The Necessity of Cyber University. Within the rapidly changing environment of global economics, the environment of higher education in the universities, also, has been, encountering various changes. Popularization on higher education related to 1lifetime education system, putting emphasis on the productivity of education services and the acquisition of competitiveness through the market of open education, the breakdown of the ivory tower and the Multiversitization of universities, importance of obtaining information in the universities, and cooperation between domestic and oversea universities, industry and educational system must be acquired. Therefore, in order to adequately cope wi th these kinds of rapid changes in the education environment, operating Cyber University by utilizing various information technologies and its fixations such as Internet, E-mail, CD-ROMs, Interact ive Video Networks (Video Conferencing, Video on Demand), TV, Cable etc., which has no time or location limitation, is needed. Using informal ion and telecommunication technologies, especially the Internet is expected to Or ing about many changes in the social, economics and educational area. Among the many changes scholars have predicted, the development and fixations of Distant Learning or Cyber University was the most dominant factor. In the case of U. S. A., Cyber University has already been established and in under operation by the Federate Governments of 13 states. Any other universities (around 500 universities has been opened until1 now), with the help of the government and private citizens have been able to partly operate the Cyber University and is planning on enlarging step-by-step in the future. It could be seen not only as U. S. A. trying to elevate its higher education through their leading information technologies, but also could be seen as their objective in putting efforts on subordinating the culture of the education worldwide. UTRA University in U. S. A., for example, is already exporting its class lectures to China, and Indonesia regions. Influenced by the Cyber University current in the U.S., the Universities in Korea is willing .to arrange various forms of Cyber Universities. In line with this, at JUNAM National University, internet based Cyber University, which has set about its work on July of 1997, is in the state of operating about 100 Cyber Universities. Also, in the case of Hanam University, the Distant Learning classes are at its final stage of being established; this is a link in the rapid speed project of setting an example by the Korean Government. In addition, the department of education has selected 5 universities, including Seoul Cyber Design University for experimentation and is in the stage of strategic operation. Over 100 universities in Korea are speeding up its preparation for operating Cyber University. This form of Distant Learning goes beyond the walls of universities and is in the trend of being diffused in business areas or in various training programs of financial organizations and more. Here, in the hope that this material would some what be of help to other Universities which are preparing for Cyber University, I would 1ike to introduce some general concepts of the components forming Cyber University and Open Education System which has been established by JUNAM University. System of Cyber University could be seen as a general solution offered by tile computer technologies for the management on the students, Lectures On Demand, real hour based and satellite classes, media product ion lab for the production of the multimedia Contents, electronic library, the Groupware enabling exchange of information between students and professors. Arranging general concepts of components in the aspect of Cyber University and Open Education, it would be expressed in the form of the establishment of Cyber University and the service of Open Education as can be seen in the diagram below.

  • Smartphone and its applications (i.e. apps) are increasingly penetrating consumer markets. According to a recent report from Korea Communications Commission, nearly 50% of mobile subscribers in South Korea are smartphone users that accounts for over 25 million people. In particular, the importance of smartphone has risen as a geospatially-aware device that provides various location-based services (LBS) equipped with GPS capability. The popular LBS include map and navigation, traffic and transportation updates, shopping and coupon services, and location-sensitive social network services. Overall, the emerging location-based smartphone apps (LBA) offer significant value by providing greater connectivity, personalization, and information and entertainment in a location-specific context. Conversely, the rapid growth of LBA and their benefits have been accompanied by concerns over the collection and dissemination of individual users' personal information through ongoing tracking of their location, identity, preferences, and social behaviors. The majority of LBA users tend to agree and consent to the LBA provider's terms and privacy policy on use of location data to get the immediate services. This tendency further increases the potential risks of unprotected exposure of personal information and serious invasion and breaches of individual privacy. To address the complex issues surrounding LBA particularly from the user's behavioral perspective, this study applied the privacy calculus model (PCM) to explore the factors that influence the adoption of LBA. According to PCM, consumers are engaged in a dynamic adjustment process in which privacy risks are weighted against benefits of information disclosure. Consistent with the principal notion of PCM, we investigated how individual users make a risk-benefit assessment under which personalized service and locatability act as benefit-side factors and information privacy risks act as a risk-side factor accompanying LBA adoption. In addition, we consider the moderating role of trust on the service providers in the prohibiting effects of privacy risks on user intention to adopt LBA. Further we include perceived ease of use and usefulness as additional constructs to examine whether the technology acceptance model (TAM) can be applied in the context of LBA adoption. The research model with ten (10) hypotheses was tested using data gathered from 98 respondents through a quasi-experimental survey method. During the survey, each participant was asked to navigate the website where the experimental simulation of a LBA allows the participant to purchase time-and-location sensitive discounted tickets for nearby stores. Structural equations modeling using partial least square validated the instrument and the proposed model. The results showed that six (6) out of ten (10) hypotheses were supported. On the subject of the core PCM, H2 (locatability ${\rightarrow}$ intention to use LBA) and H3 (privacy risks ${\rightarrow}$ intention to use LBA) were supported, while H1 (personalization ${\rightarrow}$ intention to use LBA) was not supported. Further, we could not any interaction effects (personalization X privacy risks, H4 & locatability X privacy risks, H5) on the intention to use LBA. In terms of privacy risks and trust, as mentioned above we found the significant negative influence from privacy risks on intention to use (H3), but positive influence from trust, which supported H6 (trust ${\rightarrow}$ intention to use LBA). The moderating effect of trust on the negative relationship between privacy risks and intention to use LBA was tested and confirmed by supporting H7 (privacy risks X trust ${\rightarrow}$ intention to use LBA). The two hypotheses regarding to the TAM, including H8 (perceived ease of use ${\rightarrow}$ perceived usefulness) and H9 (perceived ease of use ${\rightarrow}$ intention to use LBA) were supported; however, H10 (perceived effectiveness ${\rightarrow}$ intention to use LBA) was not supported. Results of this study offer the following key findings and implications. First the application of PCM was found to be a good analysis framework in the context of LBA adoption. Many of the hypotheses in the model were confirmed and the high value of $R^2$ (i.,e., 51%) indicated a good fit of the model. In particular, locatability and privacy risks are found to be the appropriate PCM-based antecedent variables. Second, the existence of moderating effect of trust on service provider suggests that the same marginal change in the level of privacy risks may differentially influence the intention to use LBA. That is, while the privacy risks increasingly become important social issues and will negatively influence the intention to use LBA, it is critical for LBA providers to build consumer trust and confidence to successfully mitigate this negative impact. Lastly, we could not find sufficient evidence that the intention to use LBA is influenced by perceived usefulness, which has been very well supported in most previous TAM research. This may suggest that more future research should examine the validity of applying TAM and further extend or modify it in the context of LBA or other similar smartphone apps.

  • Recently, user-created content (UCC) have emerged as popular medium of on-line participation among users. The Internet environment has been constantly evolving, attracting active participation and information sharing among common users. This tendency is a significant deviation from the earlier Internet use as an one-way information channel through which users passively received information or contents from contents providers. Thanks to UCCs online users can now more freely generate and exchange contents; therefore, identifying the critical factors that affect content-generating activities has increasingly become an important issue. This paper proposes a set of critical factors for stimulating contents generation and sharing activities by Internet users. These factors were derived from the theories of folklores such as tales and songs. Based on some shared traits of folklores and UCC content, we found four critical elements which should be heeded in constructing UCC contents, which are: context of culture, context of situation, skill of generator, and response of audience. In addition, we selected three major UCC websites: a specialized contents portal, a general internet portal, and an official contents service site, They have different use environments, user interfaces, and service policies, To identify critical factors for generating, sharing and transferring UCC, we traced user activities, interactions and flows of content in the three UCC websites. Moreover, we conducted extensive interviews with users and operators as well as policy makers in each site. Based on qualitative and quantitative analyses of the data, this research identifies nine critical factors that facilitate contents generation and sharing activities among users. In the context of culture, we suggest voluntary community norms, proactive use of copyrights, strong user relationships, and a fair monetary reward system as critical elements in facilitating the process of contents generation and sharing activities. Norms which were established by users themselves regulate user behavior and influence content format. Strong relationships of users stimulate content generation activities by enhancing collaborative content generation. Particularly, users generate contents through collaboration with others, based on their enhanced relationship and specialized skills. They send and receive contents by leaving messages on website or blogs, using instant messenger or SMS. It is an interesting and important phenomenon, because the quality of contents can be constantly improved and revised, depending on the specialized abilities of those engaged in a particular content. In this process, the reward system is an essential driving factor. Yet, monetary reward should be considered only after some fair criterion is established. In terms of the context of the situation, the quality of contents uploading system was proposed to have strong influence on the content generating activities. Among other influential factors on contents generation activities are generators' specialized skills and involvement of the users were proposed. In addition, the audience response, especially effective development of shared interests as well as feedback, was suggested to have significant influence on contents generation activities. Content generators usually reflect the shared interest of others. Shared interest is a distinct characteristic of UCC and observed in all the three websites, in which common interest is formed by the "threads" embedded with content. Through such threads of information and contents users discuss and share ideas while continuously extending and updating shared contents in the process. Evidently, UCC is a new paradigm representing the next generation of the Internet. In order to fully utilize this innovative paradigm, we need to understand how users take advantage of this medium in generating contents, and what affects their content generation activities. Based on these findings, UCC service providers should design their websites as common playground where users freely interact and share their common interests. As such this paper makes an important first step to gaining better understand about this new communication paradigm created by UCC.

  • 고객만족제고에 관심을 기울이고 노력을 경주하는 기업이 늘어나면서, 유통업자들에게 고객만족제고 인센티브를 제공함으로써 그들의 고객만족노력을 불러일으키고자 하는 노력 역시 활발해 지고 있다. 이러한 노력은 상호 경쟁하는 멀티채널을 운용하는 기업들 역시 마찬가지이다. 그러나 지금까지의 고객만족제고방안에 관한 연구는 종업원이나 단일유통업자 등단일주체에 초점을 두고 진행되어 왔을 뿐 경쟁이 발생하는 멀티채널 상황에서의 고객만족제고 인센티브에 대해서는 별다른 연구가 이루어지지 않고 있다. 이러한 문제의식에서 출발하여, 본 연구에서는 게임이론에 기반한 수리경제학적 분석을 통해 멀티채널을 운용하는 기업의 고객만족제고방안에 주안점을 두어 제조업자가 두 유통업자를 운용하는 멀티채널 모형을 상정하여 고객만족제고 인센티브를 어떻게 제시하는 것이 바람직한지 규명하였다. 본 연구의 주요결과는 다음과 같다: (1)명성수준이 높을수록 고객만족제고 인센티브 수준을 높이는 것이 바람직하다. (2)멀티채널 사이의 보완적 외부효과가 클수록 고객만족제고 인센티브 수준을 높이는 것이 바람직하다. (3)유통비용이 클수록 멀티채널에서의 고객만족제고 인센티브의 수준은 낮게 제시하는 것이 바람직하다. (4)채널간 경쟁강도가 높을수록 고객만족제고 인센티브 수준을 높이는 것이 바람직하다.

  • In the past twenty years, there has been a rapid increase in the volume of traffic in Korea due to the Korean great growth of the Korean economy. Since transformation provides an infrastructure vital to economic growth, it becomes more and more an integral part of the Korea economy. The importance of coastal shipping stands out in particular, not only because of the expansion limit on the road network, but also because of saturation in the capacity of rail transportation. In spite of this increase and its importance, coastal shipping is falling behind partly because it is givenless emphasis than ocean-going shipping and other inland transportation systems and partly because of overcompetition due to excessive ship tonnage. Therefore, estimating and planning optimum ship tonnage is the first take to develop Korean coastal shipping. This paper aims to estimate the optimum coastal ship tonnage by computer simulation and finally to draw up plans for the ship tonnage balance according to supply and demand. The estimation of the optimum ship tonnage is peformed by the method of Origin -Destimation and time series analysis. The result are as follows : (1) The optimum ship tonnage in 1987 was 358, 680 DWT, which is 54% of the current ship tonnage (481 ships, 662, 664DWT) that is equal to the optimum ship tonnage in 1998. this overcapacity result is in excessive competition and financial difficulties in Korea coastal shipping. (2) The excessive ship tonnage can be broken down into ship types as follows : oil carrier 250, 926 DWT(350%), cement carrier 9, 977 DWT(119%), iron material/machinery carrier 25, 665 DWT(117%), general cargo carrier 17, 416DWT(112%). (3) the current total ship crew of 5, 079 is more than the verified optimally efficient figure of 3, 808 by 1271. (4) From the viewpoint of management strategy, it is necessary that excessive ship tonnage be reduced and uneconomic outdated vessels be broken up. And its found that the diversion into economically efficient fleets is urgently required in order to meet increasing annual rate in the amounts of cargo(23, 877DWT). (5) The plans for the ship tonnage balance according to supply and demand are as follows 1) The establishment of a legislative system for the arrangement of ship tonnage. This would involve; (a) The announcement of an optimum tonnage which guides the licensing of cargo vessels and ship tonnage supply. (b) The establishment of an organization that substantially arrangement tonnage in Korea coastal shipping. 2) The announcement of an optimum ship tonnage both per year and short-term that guides current tonnage supply plans. 3) The settlement of elastic tariffs resulting in the protect6ion of coastal shipping's share from other tonnage supply plans. 4) The settlement of elastic tariffs resulting in the protection of coastal shipping's share from other transportation systems. 4) Restriction of ocean-going vessels from participating in coastal shipping routes. 5) Business rationalization of coastal shipping company which reduces uneconomic outdated vessels and boosts the national economy. If we are to achieve these ends, the followings are prerequisites; I) Because many non-licensed vessels are actually operating and threatening the safe voyage of the others in Korea coastal routes, it is necessary that those ind of vessels be controlled and punished by the authorities. II) The supply of ship tonnage in Korean coastal routes should be predently monitored because most of the coastal vessels are to small to be diverted into ocean-going routes in case of excessive supply. III) Every ship type which is engaged in coastal shipping should be specialized according to the characteristics of its routes as soon possible.

  • 최근 컨테이너터미널에서 물량유치에 심혈을 기울이고 있으며, 선사가 컨테이너터미널을 결정하는 요소는 입지조건, 하역능력, 보관, 운송에 연계된 모든 요소들에 사항을 참조하여 선사에게 유리한 조건의 컨테이너터미널을 선별 선택한다. 컨테이너터미널의 On-Dock 서비스 가능 여부 또한 선사가 컨테이너터미널을 선택을 결정짓는 요소의 한 부분으로 중요하게 인식되고 있다. 본 논문에서 On-Dock 시스템의 업무적 알고리즘, 엠티 컨테이너 반출 알고리즘, 풀 컨테이너 알고리즘을 제시하고 On-Dock 시스템을 이용하여 작업 우선 순위 알고리즘, 반출입 작업 우선순위 알고리즘, 엠티 컨테이너 야드 장치 할당 규칙 알고리즘을 통해서 컨테이너를 자동 할당 방식과 수동 할당 방식을 이용해서 컨테이너 반출 시간 및 컨테이너터미널의 효율적인 운영 방안을 알아보고자 한다. 이를 통해 반출 컨테이너 우선순위 지정 및 장치장의 블럭을 지정하여 반출 컨테이너 할당을 제어 한다. 즉, 최적 컨테이너 선정 알고리즘을 통해서, 컨테이너터미널은 엠티 컨테이너 반출 시간을 줄이고, 야드의 컨테이너에 대해서 불필요한 리핸들링을 최소화 할 수 있으므로 장비의 효율을 높일 수 있다. Non On-Dock과 On-Dock 시스템의 작업 운영 결과는 실제 광양컨테이너터미널에서 운영되고 있는 반출 작업 운영(시나리오) 형태를 이용하여 결과를 도출하였다. 광양컨테이너터미널에서 On-Dock 시스템을 적용하게 되며, Non On-Dock 시스템을 적용 할 때 보다 시간이 약5분 정도 신속하게 반출이 가능하다. On-Dock 서비스를 이용하여 선사에서 수출 오더를 관리하기 위해서 엠티 컨테이너를 배정 하고, 수입 화물에 대해서는 D/O를 관리하며 반출 후 회수 관리와 컨테이너의 손상, 청소, 수리, 제어 등의 서비스를 지원하므로 대외 선사 서비스를 강화하여 컨테이너터미널 물량 유치 및 영업 증대를 꾀할 수 있을 것이다.
