The purpose of this study is to investigate the user's perception of security risk and examine its impact on the usage of Knowledge Management Systems(KMS). The findings of this study are three-fold. First, the overall user's perception of security risk is not high. However, there is a considerably big difference in the perception of security risk among users. This finding means that user's perception of a security risk is not based on the actual security effects but one's individual perception. Another finding is that user's perception of a security risk has a negative impact on the usage of KMS through "trust", which is a mediating variable in our study. This finding corresponds with the existing theory that security risk is oneof the critical sources of trust, and trust is a critical factor of user's acceptance of KMS. Finally, the result of this study reveals that activities devoted to security do not decrease the effectiveness and productivity of KMS. Our long-held cognition that security activity hinders the effectiveness and productivity of an information system is not particularly applied to the KMS.

To design and develop secure operating systems, the BLP (Bell-La Padula) model that represents the MLP (Multi-Level Policy) has been widely adopted. However, user\`s security level in the most developed systems based on the BLP model is inherited to a process that is actual subject on behalf of the user, regardless whatever the process behavior is. So, there could be information disclosure threat or modification threat by malicious or unreliable processes even though the user is authorized in the system. These problems can be solved by defining the subject as (user, process) ordered pair and by defining the process reliability. Moreover, when the leveled programs which exist as objects in a disk are executed by a process and have different level from the process level, the security level decision problem occurs. This paper presents an extended BLP (E-BLP) model in which process reliability is considered and solves the security level decision problem. And this model is implemented into the Linux kernel 2.4.7.

Purpose - This study aims to examine the effect of audience attitude toward product placement, or PPL, on product attitude and purchase intention. PPL has increasingly been prevailing in TV dramas since the revision of the Broadcasting Act in January 2010, and it is quite widespread in today's society. Therefore, this study intends to investigate how the audience would take a particular attitude toward PPL in TV dramas and how their attitude would affect their product attitude and purchase intention. Research design, data, and methodology - The sample for the current study was drawn from college students in Seoul in December 2013, as the main targets of the products and brands that were advertised by PPL are young people. The questionnaire for this study comprised nine parts, such as the knowledge of PPL, experience of PPL, TV drama watching time, impulsive buying propensity, celebrity imitating buying propensity, attitude toward PPL, attitude toward product, purchase intention, and demographic characteristics. The questionnaire items were measured by 5-point Likert scales. Whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed and how the PPL attitude would affect purchase intention through product attitude was analyzed as well. To analyze the relationship between variables, structural equation modeling analysis was performed with Amos 18.0. Results - The major findings of the study were as follows. First, whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed, and it is found that out of the demographic characteristics, only gender and knowledge of PPL exerted an influence on PPL attitude. In addition, celebrity-imitating buying propensity had an impact on PPL attitude. Second, whether PPL attitude would affect purchase intention through product attitude was analyzed by structural equation modeling. Consequently, it is found that PPL attitude impacted purchase intention through product attitude. Conclusions - The findings of the study had the following implications. First, in theoretical aspects, previous studies have proven only that attitude toward PPL influenced attitude toward product and purchase intention separately; however, the current study has investigated the mediated role of attitudes toward PPL. Second, regarding the practical aspects, as PPL attitude exercised an effect on purchase intention as well as product attitude, PPL should be utilized in a manner to stimulate the audience to take a positive attitude to it. Finally, gender, PPL knowledge, and celebrity-imitating buying orientation were identified as influential factors for PPL attitude. Specifically, female consumers showed a lower attitude toward PPL than males, and the consumers who have no knowledge showed a lower attitude toward PPL. The consumers who have celebrity imitating buying propensity expressed a higher attitude toward PPL. These factors should consequently be taken into account when PPL is planned and conducted. The current study has limitations such as the sample object, non- experimental method, and media biases. Therefore, future research should be conducted to address these limitations.

The purposes of this study were (1) to analyze price sensitivity, (2) to define the range of acceptable prices for each foreign segment, and (3) to provide a price model for Korean traditional restaurants. From October to November, 2006, a total of 781 foreigners responded to individual surveys. Statistical analyses on the survey data were performed using descriptive statistics and Price Sensitivity Measurement (PSM). Major findings from the study are as follows: First, the ranges of the acceptable prices were $98$\sim$$130 for fine dining/gourmet restaurants, $70$\sim$$90 for theme/ambience restaurants, $40$\sim$$60 for popular/family restaurants, and $18$\sim$$30 for convenience/fast food restaurants. Second, the convenience/fast food restaurants showed the highest price sensitivity. Third, a low stress level and wide range of the acceptable price were observed for the fine dining/gourmet restaurants, suggesting that the price sensitivity of the fine dining/gourmet restaurants was quite low. Finally, the price sensitivity indicated by the Japanese was higher than by the other groups. In consequence, the research findings suggest that the managers of the Korean traditional restaurants should strategically plan prices by understanding different customers' price sensitivity within and between customer segments. Through additional research, marketers can compare perceptions of specific brands, the competition, and variations within a product line.

This study aims to investigate the context of materials in literature textbooks and the awareness about the educational value of classical literature, as part of an interest in literature education phenomena. This study accepts the premise that textbooks affect the practice of classical literature education and, in particular, materials in textbooks are chosen according to the intentions, demands, and perspectives of education in specific social conditions. I divided the educational value of classical literature into two categories, classical and literary value, and investigated the actual conditions and context of materials of literature textbooks based on the 2009 revised curriculum and the 2011 revised curriculum. Classical literature is generally alienated and excluded; contemporary literature materials are mostly included and organized in the domains of 'the role of literature', 'reception and production of literature' and 'literature and life.' In addition, the tendency to heighten classical value and diminish literary value is deepening. In order to solve the problem that classical literature is only included as the product of the past, changes must be made not just to the curriculum, which are external changes, but to the awareness of the essence of classical literature, which are internal changes. Above all, generality as 'literature' and the sense of distance about space and time as 'classic' should be connected to various relationships which respond to problematic situations and the demands of learners. Based on the relationships, we can expect a rich diversity of contexts and aspects of included classical literature. In addition, an extension of the width and scope of included classical literature is anticipated. The reduction of workload, the advent of the concept of capability and the dissolution of traditional literature concepts are the changes of external environment, which is continuously requiring renewed investigation into classical literature beyond simple appropriateness.

공공수역 수질오염 관리에 있어 비점오염원 관리의 중요성이 크게 부각되고 있다. 새만금호 유역은 농경지비율이 40%로서 넓기 때문에 농업비점오염 관리가 중요하다. 농업비점오염 저감을 위한 기법 연구는 국내에서 그 간 상당 수준으로 진행되었지만, 그 기법을 실행할 주체인 농업인이나 지역주민의 역량이나 농업비점오염의 인지도에 대한 연구는 부족한 실정이다. 본 연구는 새만금유역에서 농업비점오염과 관련된 주체들 간의 정보의 소통과 흐름에 대하여 분석해보고, 또한 농업오염 교육 전후에 있어서 지역주민과 농업인의 농업비점오염에 대한 인식도와 교육효과에 대해서 살펴보았다. 먼저, 농업비점오염과 관련된 주체들 간의 지식흐름은 매크로레벨 즉, 정책입안자, 전문가 레벨에서 관련정보가 정체되어 있었고, 실제 농업비점오염 관련 저감 기법이나 정책을 실행하는 주체인 마이크로레벨의 농업인과 지역주민, 이를 지원하는 시군 공무원, 지역전문가 등 매소레벨을 지원하기 위한 정보로 가공 전달되지 못하고 있었다. 농업부서와 환경부서 사이의 농업비점오염에 대한 인식도의 차이가 크게 나타났으며, 특정 분야를 중심으로 활발한 소통이 있는 반면, 정보의 의도적 차단, 자기조직의 대응을 위한 형식적, 임시적 소통이 이루어지고 있었다. 귀농인과 친환경농업인에 대한 교육을 통하여 농업비점오염에 대한 인식도는 교육 전 38.1%에서 교육 후 100%로, 교육 후 농업비점이 오염원이라는 인식도도 친환경농업인 91%, 귀농귀촌인 78%로 응답하였다. 농업비점오염원 관리가 수질개선에 미치는 효과에 대하여는 친환경농업인은 5점 만점에 3.67점, 귀농귀촌인은 4.05점, 농업비점오염원 관리가 필요한지에 대하여 친환경농업인은 4.05점, 귀농귀촌인은 4.09점으로 두 집단 모두 농업비점오염원 관리가 필요하다고 응답하였다. 반면, 친환경 농업은 저감기법의 오염 저감 효과는 높게 인식하였지만, 직접 실행해 볼 의사는 3.4점, 저감 기법을 주위에 소개나 권고할 의사는 3.5점이었다. 또한, 실행 가능한 저감 기법으로는 퇴액비 사용, 완효성 비료사용, 녹비작물재배 등의 순이었다. 저감기법이 어렵다고 응답한 이유는 복잡할거 같다, 귀잖을 것 같다, 추가비용으로 손해, 저감효과 신뢰성 부족, 농업은 오염원이 아니다 등으로 나타났다. 이상의 연구결과를 살펴볼 때, 주체들 간의 정보와 지식흐름을 이어줄 중간조직의 필요성과 농업인의 인식의 변화가 행동의 변화로 이어질 수 있는 교육?홍보 기법과 농업인의 수용성이 높은 저감기법의 개발과 보급이 필요함을 시사하였다.

본고는 중세도시연구의 관점에서 도성 헤이안쿄(平安京)가 중세 교토(京都)로 변화하는 계기와 그 의미, 그것이 새로운 무가(武家) 정권도시(政權都市)에 어떤 영향을 미쳤는지에 대하여 논하였다. 율령제 마지막 도성인 헤이안쿄는 천황을 절대적 정점으로 한 중앙집권이 동심원구조로 구현된 '왕성(王城)의 땅'이었으나, 10세기 후반 이후 도성의 구심점이었던 내리(內裏)가 헤이안큐(平安宮) 밖으로 나오는 등의 변화가 시작되었고, 도성의 이념과 틀이 급속하게 해체 변용되었다. 또 고대왕권을 대신하여 새로운 형태로 왕권과 여러 권력을 담당한 원(院)과 롱관가(瀧關家), 대두하는 무가권력 등이 그 본거지에 권력의 개성과 시대성을 반영한 새로운 경관과 공간원리를 생성하였다. 그것은 다음과 같은 공통점을 갖는다. (1) 큰 정토정원을 갖는 御堂(사찰)과 세트를 이룬 御所(천황의 거소). (2)황통(천황가 내의 계통)과 가족의 상징으로서 조상을 모신 분묘를 중심으로 한 도시형성. (3) 내리를 기점으로 남북으로 주축을 갖는 고대도성과 달리, 어당과 어소가 동서로 배열된 동서가로를 주축으로 한 도시계획. (4) 수도와 외부를 잇는 교통의 결절점에 입지하였고, 특히 하천변을 향해 적극적으로 확장된 도시. 일본 중세는 무가정권의 시대를 맞이하여 도고쿠(東國) 초기 무가정권의 본거지 히라이즈미(平泉)와 최초의 막부가 열린 가마쿠라(鎌倉)가 모델로 한 것은 '도성 헤이안큐'가 아니라 헤이안큐 수도 밖 신도시의 경관과 공간원리였다. 특히 히라이즈미와 가마쿠라 등이 가정기관(家政機關)과 조상의 묘를 중심으로 한 '가족 원리'에 따른 정권도시를 적극적으로 수용한 것은 단순한 도시의 모방이 아니라 주종관계를 축으로 의제적인 '집(家) 원리'로 권력이 형성된 무가에는 더욱 어울리는 논리이며, 또 고대와는 다른 새로운 시대의 논리였기 때문이다. 그 한편으로 무가의 대들보로서 무사들에 의해 추대된 초기 무가정권은 도시의 논리와 경관을 도입하였을 뿐 아니라 그들과 공통의 가치관을 표현하는 것도 중요한 요소였다. 그것이 최신의 도시를 모방한 어당과, 그것과는 대조적인 도고쿠 무가의 전통적인 어소의 병립이라는 종교공간과 정치 일상공간에서의 권위표상의 의식적인 분리에 의해 표현되었다. 히라이즈미와 가마쿠라에서는 유통, 상공업 등의 도시기능과 도시적인 경관이 정비되기까지 약 50년의 시간이 경과할 필요가 있었다. 12세기 일본의 무가정권은 스스로의 거점으로서 도시를 기획, 형성하는 의식과 실현하는 능력을 얼마나 가지고 있었는가 검토가 필요하다. 명확한 동아시아모델의 도성을 실현함으로써 왕권의 존재를 드러낸 고대 율령정권과의 차이점은 매우 크다. 이후 무가가 권력의 의도를 도시구조로서 명확하게 드러낸 것은 15세기 후반의 전국시대 다이묘(大名)의 죠카마치(城下町)로부터이다. 특히 16세기 후반부터 천하통일을 실현한 오다 노부나가, 도요토미 히데요시의 연합정권에서는 구체적인 성(城)과, 그 성을 중심으로 한 계층성을 명시한 죠카마치의 공간설계가 있었다. 여기서는 다시금 '도시의 경관'이 명확한 권력의 상징으로서 기능하게 된 것이다.

Park Se-dang who has the pen name of Seogye is a man in the 17th century. Then, Joseon Dynasty is try to restore the state which became impoverished by two wars. When Sung Confucianism of Chu-tz was dogmatized, Seogye analyzed independently the scriptures and was regarded as a traitor against Sung Confucianism. Therefore, this paper discussed the understanding of Seogye's works and its social reflection through the research data about Seogye. Although Seogye has blue blood in his veins, he belonged to a non-mainstream group in the faction of Seo-in and had a liberal inclination. That he has shuned in the school of Sung Confucianism owed to Sabyeunrok of his work, and its main reason is his criticism against Song Si-yeul. He argued the two principles different from Chu-tz's three principles. Also, he not accepted the Chu-tz's theory and was similar to the Wang Yangming school in the issue of gaining knowledge by the study of things Now to conclude, Seogye outstretched the liberal inclination in Sung Confucianism apart from the interpretation of scriptures. He was not indulged in Sung Confucianism of Chu-tz that was gradually ossifying at that time and took his own line. And he devoted himself to the study of practical learning and the education for younger scholars, and had acted as mediator between the Sung Confucianism of Chu-tz and the Practical Science that was in full bloom in the period of King Young-jo and King Jeong-jo.
