Interpretive sign is a communication medium that is often used in self-guided interpretation. Understanding interpretive signs and their users is important to maximize the effectiveness of interpretation. This study evaluated design attributes of interpretive signs by visitor's personal characteristics and visiting patterns using Importance-Performance Analysis(IPA). Data were collected from August to September of 2003 at the self-guided trail in Naejangsan National Park, Korea. Visitors using the trail participated in a questionnaire survey, and a total of 276 subiects was used for data analysis. The IPA results showed that female(23.3%) than male(13.3%), low age group(43.3%) than middle(0.0%) and high age group(0.0%), higher education group(36.7%) than lower education group(0.0%), medium size group(33.3%) than large(10.0%) or small group(16.7%), 'with child' group(66.7%) than 'without child' group(20.0%) rated higher importance and lower performance on more design attributes of the interpretive signs. These groups also showed higher rate of 'Concentrate Here(CH)' attributes that require urgent improvement. The 'with child' group showed the especially high rate of 'CH' attributes. The results suggest that interpretive signs need to be designed considering diverse user groups. It is also necessary to develop some standardized items of the sign design attributes for more efficient and reliable implementation of IPA and other evaluative works.

This study is primarily concerned with the criteria for choosing a legitimate state plaintiff in cases involving a states request to media for a right of reply. Interpretation of the right of reply itself is different from country to country because of different constitutional views and systems in each state. Unlike the United States, the constitution of the Republic of Korea does not expressly prohibit the making of laws adversely affecting freedom of the press. Accordingly, in Korea freedom of the press may be restricted through legislation within certain limits and the right of reply is not incompatible with the spirit of the constitution. An analysis of relevant law makes it clear that the particular agency aggrieved should initiate the suit rather than the Justice Minister. The idea that the Justice Minister should assume the role of plaintiff in all state cases seems to stem from flawed interpretations of provisions in the Law Governing Registration of Periodicals and the Law Governing Litigation Involving the State. Even though each state agency has the right of reply, it should be cautioned not to abuse it as the states frequent involvement in litigation may bring on unnecessary misunderstanding and have a chilling effect on the media. The right of reply does not always imply that a certain media report in question is wrong and the media should be sanctioned for it. The right of reply is basically intended to help the general public make an informed judgment on issues presented in the media and insure fairness and balance.

The background of this study was to consider regenerative environmental characteristics and develop foundations for conceptual grounds and applications in embodying sustainable garden designs demanded in our age. In doing so, this study aimed to have a conceptual understanding of Clement's garden theory influenced by Robinson's naturalistic distinction and compared it with Robinson's wild garden, and the results are as follows: First, for Clement, garden design included an ecological process to settle in the target site as aesthetics of space being formed by the movement of plants. In this sense, making a 'garden in motion' implies to design possibilities to adapt to nature based on trust in it and allow plant seeds not to be planned but to naturally go and find appropriate habitats. Second, the views to wildness can be separated into microscopic and macroscopic views and each has its own expressive characteristics. Robinson's gardens are small and subordinate and play mollification functions for existing spaces. On the contrary, Clement's gardens are the subject of the space, represent macroscopic strategies, and have top-down approaches embodied as infrastructure to play central roles in the ecology. Third, Robinson's and Clement's views to the operation of garden spaces acknowledge the inseparable relationship between nature's autonomy and gardens' wildness and deliver a value that the preservation of nature is a prerequisite to coexistence with the life we desire. Their gardens are analogized by interventions of environmental possibilism and ecological standpoints mediated by plants based on the perspective of environmental determinism.

The wireless transmission medium inherently broadcasts a signal to all neighbor nodes in the transmission range. Existing asynchronous MAC protocols do not provide a concrete solution for reliable broadcast in link layer. This mainly comes from that an omni-directional broadcasting causes to reduce the network performance due to the explosive collisions and contentions. This paper proposes a reliable broadcast protocol in link taller based on directional antennas, named MDB(MAC protocol for Directional Broadcasting). This protocol makes use of DAST(Directional Antennas Statement Table) information and D-MACA(Directional Multiple Access and Collision Avoidance) scheme through 4-way handshake to resolve the many collision problem wit]1 omni-directional antenna. To analyze its performance, MDB protocol is compared with IEEE 802.11 DCF protocol [9] and the protocol 2 of reference [3], in terms of the success rate of broadcast and the collision rate. As a result of performance analysis through simulation, it was confirmed that the collision rate of the MDB protocol is lower than those of IEEE 802.11 and the protocol 2 of reference [3], and that the completion rate of broadcast of MDB protocol is higher than those of IEEE 802.11 and the protocol 2 of reference [3].

This discussion can be said to be a qualitative study on the possibility of linking communication education for college students and literacy education for Korean language-linked educators based on the theory of interpretation of cognitive meaning of media text containing complex mechanisms. The implicit meaning of media content expression used as an interactive communication strategy will be accepted as a multilateral interpretation according to the individual learner's cognitive environment. If so, how is the general media content meaning intended by the content creator being accepted? These doubts are the starting point for discussion. To solve the problem, I leaned on the experimental pragmatic methodology of cognitive aesthetics and applied a model of relevance of cognitive linguistics to connect learners' creative cognitive environment and present content to find a contrast. As a result of the discussion, it was possible to establish a basic framework for learners to express their subjectivity and creative thinking that could connect the cognitive environment and present content themselves. In particular, active and positive learners also revealed direct descriptive expressions to build a new cognitive environment, such as suggesting a third alternative to argue the ability to question produced media texts and the validity of the meaning implied in the text. In the future, since media text containing complex mechanisms is an indirect and persuasive communication behavior that occurs easily through various media in modern society, the universal communication principle of reliable conversation between media text creators and audiences should exist.

Affect is intensity and quality that are generated as the physical body senses the outside world. Of experienced affect, notions that are granted meaning and interpretation are emotions. Affect theory distinguishes emotion and affect and by focusing on affect, it provides methods with which to analyze physical body responses and changes and it presents new possibilities to performing arts research that uses the physical body as a medium. Nong-ak is art that concentrates mainly on the occurrence of affect rather than 'representation'. Nong-ak is a performance type in which sound, color, texture, and physical movement overlap and exist in a synesthetic way. Here, physical things such as instruments, props, costumes, and stage devices are gathered together with non-physical things such as rhythm, mood, and atmosphere around human bodies. The physical body is stimulated by these things, displays tendencies that suit performances, and becomes 'the body without an image' as it immerses itself into the performance, acting while displaying 'quasi-corporeality'. The body, which moves automatically as if without consciousness, appears more easily within groups. To transition individuals of everyday life to 'the body without an image', Nong-ak executes the group physical exercise of 'Jinpuri'. Such physical exercise builds up affect by increasing nonverbal communion and communication and brings out the creativity of individuals within mutual trust and a sense of belonging. Affect and emotion stirred up by Nong-ak act as confirmation and affirmation of the existence, vitality, and ability of one's self and groups. Such affirmation recalls Nong-ak as a meaningful and important value from group dimensions and perceives it as a performance form that should be preserved and passed on.

The purpose of this study was to prepare basic data for improving school library information service by investigating the information usage behavior of specialized high school students. Preferred information sources for each situation requiring information and the level of solving information problems using information sources were investigated, and difference analysis was conducted by department and grade. As a result of the survey, the percentage of students who preferred Internet portal services, personal information sources (teachers, friends, parents), and social media was high, while the percentage of students who preferred traditional print information sources and mass media was very low. The average score of the information problem solving level was 3.55, and the problem solving level in the areas of employment and career/admission was relatively low. Preferred sources of information were similar regardless of grade and department, and the difference between departments in information problem solving level was not statistically significant, but the difference between grades was statistically significant. In addition, there is an academic contribution in this field that specific examples of youth information use behavior have been added. Based on the results of the study, librarians should make efforts to verify the reliability of Internet portal site information, improve and promote library information sources, and expand library use education. In future studies, it was suggested to develop customized information services.

A current source capable of stably supplying current as a measurement medium is required in order to measure and test important facilities that require large-scale measurement current, such as a control element drive mechanism control system(CEDMCS), in case of dismantling a nuclear power plant. However, it can provides only voltage power as a source, not current, although direct voltage controlled constant current source is essential to test major equipment. That kind of source is not available to supply stable constant current regardless of load variation. It is just voltage supplier. Developing current source is not easy other than voltage source. Very large-scale current source up to ampere class more than such ten times of normal current is inevitable to test above mentioned equipment. So, we developed large-scale current source which is controlled by input DC voltage and supplies constant stable current to object equipment according to this requirement. We measured and tested nuclear power plant equipment using given real site data for a long time and afforded long period load test, and then proved its validity and verification. The developed invetion will be used future installed important equipment measuring and testing.

Recently, Virtual Human(VH) has begun to appear in various media, not only on social media, but also in advertisements, music sources, and dramas. Virtual human has become a primary marketing tool for companies, but there also exist concerns when the companies do not disclose the identities of virtual humans. Accordingly, it is necessary to examine users' responses toward content that features virtual humans. This study aimed to examine how the exposure of virtual humans in the content affects users' perceptions. Therefore, the study defined the concept of 'VH Disclosure(VHD)', referring to the exposure of the virtual human's identity, and explored the impact of VH disclosure on attitude toward the ad (Hedonism, Utilitarianism, and Interestingness) and source credibility (Trustworthiness and Expertise). The study conducted an experimental survey with 302 respondents. Regardless of when the ad featured a VH or a human, the results showed that there was no significant difference between users' attitudes and source credibility. The results revealed that it was more effective to disclose the VH in social media feeds than directly reveal the VH's identity in the content. Therefore, this study utilizes a new concept of 'VH Disclosure(VHD)' to enhance the understanding of VH and contributes to establishing marketing strategies optimized for consumers in the creation of virtual human-related content.

The recent increase in digital audio media has greatly expanded the size and diversity of sound data, which has increased the importance of sound data analysis in the digital forensics process. However, the lack of standardized procedures and guidelines for sound data analysis has caused problems with the consistency and reliability of analysis results. The digital environment includes a wide variety of audio formats and recording conditions, but current audio forensic methodologies do not adequately reflect this diversity. Therefore, this study identifies Life-Cycle-based sound data elemental technologies and provides overall guidelines for sound data analysis so that effective analysis can be performed in all situations. Furthermore, the identified elemental technologies were analyzed for use in the development of digital forensic techniques for sound data. To demonstrate the effectiveness of the life-cycle-based sound data elemental technology identification system presented in this study, a case study on the process of developing an emergency retrieval technology based on sound data is presented. Through this case study, we confirmed that the elemental technologies identified based on the Life-Cycle in the process of developing digital forensic technology for sound data ensure the quality and consistency of data analysis and enable efficient sound data analysis.
