  • The concept of the advanced concept technology demonstration (ACTD) has previously been introduced in USA in order to make it possible to rapidly transfer advanced technologies developed in commercial sectors to develop weapon systems in the defense area. Since then in Korea several ACTD programs have been developed and being carried out However, there are few program management methods suitable for the characteristics of the ACTD programs, which requires stringent management of the program requirements and risks due to the radically shortened development time. In this paper such a problem has been addressed and as a solution approach the quality function deployment (QFD) method has been adopted, which is being served as a successful model in various areas such as manufacturing. The QFD method is used in our study to improve communication between various stakeholders involved in the ACTD programs and also to reduce risks related to requirements. Specifically we have developed the ACTD standard templates based on the QFD method and discussed how to use the developed templates. Finally, the application of the study result is demonstrated through the ACTD program of flight information demonstration system and also specific ways are suggested to use the standard templates, to manage requirements, and to reduce risks.

  • Since the end of the $19^{th}$ century, Korean English-language newspapers have been published in Korea to inform readers about Korea and Korean people's point of view concerning world problems. Among them was the Korean Republic (KR), the former name of the Korea Herald, founded on August $15^{th}$, 1953 (Korean Liberation Day from Japanese colonial rule). This newspaper was started especially to report on international affairs, just after the Armistice agreement was signed on July $27^{th}$, 1953, at the initiative of the first president of the Republic of Korea, Syngman Rhee. He vehemently expressed his and the Korean people's opinion about Korean problems in world politics where big powers were dominating and deciding small countries' destinies. This paper is written to show that Korean English-language newspapers were used as tool of public diplomacy not only for the readers of target countries but also for Korean readers, well before the media diplomacy theory became popular several decades later. In the deplorable world situation where Korea was colonized and divided into halves by the wills of the super powers, the Korean media participated actively via dialogue in English to solve the Korean problem. This paper studies the editorials of the KR for one year, the year just after its foundation. Vis-a-vis the United States, the KR defended its political system of free democracy by insisting on the Korean people's hopes, the reunification of the peninsula and acquiring American assistance in economic and military areas. Regarding Japan, Korea had doubt about its expansionist policy by way of rearmament. First, the Korean government tried to defend its territorial waters, including Dokdo Island. As for multi-lateral relationships, Korea was concerned about the spread of communism to its territory in the world where socialism was dominating.

  • In this study, we extracted the core competencies of makers through the analysis of critical incident technique and behavioral event interview to explore the nature and attributes of maker education, and then we developed a maker competency model based on these core competencies. As a result, six competency groups and 23 sub-competencies were extracted. In other words, we were able to confirm the existence of integrated thinking competency group consisting of four competencies made up of 'analytic thinking', 'intuitive thinking', 'visual thinking', and 'empirical thinking' and that of collaborative competency group with four competencies of 'sharing', 'communication', 'conflict management', and 'scrupulosity'. In addition, we could also confirm the existence of making mind competency group, which is composed of four competencies namely 'interest in various areas', 'challenge consciousness', 'failure management', and 'pleasure of the making process'. We could also confirm that human-centered competence group consisting of two competencies of 'humanity' and 'user-oriented' and the problem-finding competence group consisting of two competencies of 'observation' and 'recognition of discomfort in daily life'. Lastly, the making practice competency group is composed of seven competencies: 'understanding making tool', 'understanding electricity', 'understanding programming', 'planning', 'hand knowledge', 'information search', and 'direct execution'. We discussed educational implications of these findings.

  • In this paper insights from studies on the middle income trap and value chains analyses are combined to investigate one particular industry in one particular region: the sugarcane industry in Northeastern Thailand. Focusing on this region enables an in-depth focus on geographical differentiation of the middle income trap. The empirical outcomes demonstrate that policymakers involved with sugar should look at the particular challenges in Northeastern Thailand: 1. The role of brokers which is unaddressed in the current regulatory environment; 2. A lack of information of the regulatory environment among growers; 3. Distrust between growers and millers; 4. Alack of implementation of R&D efforts; 5 .A lack of support from associations; 6. The labor shortage problem, and 7. No incentives for growers, brokers and millers to improve quality and embark on upgrading. Since agricultural value chains in Southeast Asia often start in relatively poor rural areas it is imperative that policymakers balance the interests of upstream, midstream and downstream actors. Unfortunately, this is rather difficult as midstream actors (millers) and wholesalers are powerful and therefore, are in the best position to defend their interests. Our insights could function as comparative material for similar studies within other Southeast Asian upstream value chains.

  • This study examined visitors' perceptions and attitudes about establishing cable car in Mudeungsan Provincial Park (MPP). Data were collected from 401 respondents by a field questionnaire survey in MPP during the September of 2010. 61.7% of respondents opposed to establishing cable car in MPP while 20.6 percent supported it. Respondents showed high level of belief to possible consequences that establishing cable car will result in 'deterioration of ecosystem and natural landscape', 'crowding problem by increased number of visitors', 'disappearance of naturalness or previous nature experiences in MPP'. Respondents, however, presented low belief to 'positive effects on increasing economic income and local economic growth by attracting tourists'. 32.4 percent of the survey respondents evaluated the present MPP as a place of 'Nature Preservation Area (NPA)' and 10.5% as 'Developed Park Area (DPA)'. 48.8% of respondents answered that MPP should be managed as 'NPA' with only 2.5% as DPA. Respondents' socio-demographic characteristics (i.e., gender, age, education level, length of residence in Gwang-ju city), use patterns (number of visits to MPP or to Jungbong and surrounding areas), and normative place condition of MPP showed relationship with the overall support rates about establishing cable car. The results and their implications were discussed.

  • Java, used as the most representative object-oriented language, isil becoming the popular language for Internet/Intranet based program development. Moreover, it is used for development language in a variety of areas such as component based development language. In the view of reuse and maintenance of developed program, quality evaluation of program is becoming a more important issue. So, metrics measurement for quality evaluation of program that is developed at present including existing Java application is necessary. However, it is necessary that whether existing object-oriented software metrics is suitable on Java program is to be validated So, in this paper, we build an automated metrics measurement system that needs to validate on object-oriented software metrics and wish to support metrics measurement that is to determine it. The purpose of this system is to support a precise quality evaluation tool. In this system, we apply the metrics classified by Briand. Briand classified the metrics by formalizing mathematically them to verify feasibility of existing object-oriented software metrics. Using the proposed system, we can make comparison and analysis of validation on existing object-oriented metrics by calculating quantitative information more rapidly from Java source program. If there is any problem in feasibility of the metrics, we can establish a suitable metrics on Java program by considering reiJ,1forcement of the existing metrics or proposing new metrics.

  • Mathematics learning disabilities is a specific learning disorder affecting the normal acquisition of arithmetic and spatial skills. Reported prevalence rates range from 5 to 10 percent and show high rates of comorbid disabilities, such as dyslexia and ADHD. In this study, the characteristics and the causes of this disorder has been examined. The core cause of mathematics learning disabilities is not clear yet: it can come from general cognitive problems, or disorder of innate intuitive number module could be the cause. Recently, researchers try to subdivide mathematics learning disabilities as (1) semantic/memory type, (2) procedural/skill type, (3) visuospatial type, and (4) reasoning type. Each subtype is related to specific brain areas subserving mathematical cognition. Based on these findings, the author has performed a basic research to develop grade specific diagnostic tests: number processing test and math word problems for lower grades and comprehensive math knowledge tests for the upper grades. The results should help teachers to find out prior knowledge, specific weaknesses of students, and plan personalized intervention program. The author suggest diagnostic tests are organized into 6 components. They are number sense, conceptual knowledge, arithmetic facts retrieval, procedural skills, mathematical reasoning/word problem solving, and visuospatial perception tests. This grouping will also help the examiner to figure out the processing time for each component.

  • A urban regeneration project of Korea has been promoted highly attaching to physical reforms, but without fulfilling the basic goal of reactivating city functions through concerning overall areas. Moreover, the general rule and its system of urban regeneration project which would provide roles of public and civilians as well as facilitate cooperative urban regeneration, are currently missing. Thus, social stratum continuously requests a framework act for urban regeneration project called Control Tower, to be a guide to the evidently right path to step up. The research analyzes the current status and problems of urban regeneration projects in Korea to examine the necessity of Control Tower, and to bring up the way to move on for its efficiency presented below: First, the law should be declarative; possess general, prospective influences on laws and systems related to urban regeneration. Second, the nonbinding guideline on a urban regeneration project should be suggested to reflect the conditions by the regions. Last, propulsions should be framed such as administrative principles of strengthening publicity and connection of urban regeneration projects, a committee and fund to promote the former, and a research for problem solution.

  • In order to solve the problem of how to estimate the residential segregation, the Spatial Concentration Index(SCI) and Location quotient(LQ) are able to be one of alternative methods, and a comprehensive analysis of the residential segregation phenomenon in the seoul metropolitan area is the aim of the study. The results of SCI show that residential concentration areas in low-rent are some Gyeonggi-do's downtown(Bucheon-si, Suwon-si) as well as rural and urban-rural complex outskirts of the metropolitan area. The results of changing of SCI from 2011 to 2014, downward changes appeared thirteen districts and upward changes appeared fourteen districts. Especially downward change district was Sosa-gu, Bucheon-si and upward change district was Yeongtong-gu, Suwon-si. In conclusion, that high rent level groups are more concentration on specific area than low rent level groups. By decreasing residential concentration districts in low-rent level group, 'diversity' districts have been increasing in seoul metropolitan but the phenomenon of residential concentration in high and low level group have been being intensified. These results could be confirmed by quantitative through LQ. Methodologically LQ would strengthen the explanatory power of SCI, and ongoing research of SCI in conjunction with other quantitative methods will need.

  • Technical change and technological innovation have become major drivers of economic progress in the knowledge oriented economies where growth, productivity, and competitiveness are increasingly based on improved technologies, novel products, upgraded processes or customized services. The creation of new knowledge, modifying or improving existent knowledge, or imitation of others, has become central to economic development. New discoveries, state-of-the-art information gathering procedures, or successful problem solving routines are often at he core of these innovations. Despite the generally acknowledged importance of science in many high-tech areas of major economic relevance, there is few science-related statistics to be found in high-profile international benchmarking reports. This paper aims to provide an answer by advancing our understanding of the possibilities of indicators quantifying linkages between science and technology. Central are the concepts of innovation capability and science/technology interface, which are used to assemble a wide range of empirical studies and quantitative indicators to summarize their possibilities and limitations for producing comparative statistics. For the purpose of the study, we extracted the US patents by Korean assignees or inventors, scientific papers cited in the patents in order to analyze the characteristics of linkage of scientific knowledge flows. The review focuses on indicators dealing with flows of written or codified information, and indicators of inventiveness that capture the non-codifiable tacit knowledge dimension. General conclusions will be drawn with a view towards further developments in the foreseeable future, suggesting new avenues for the design and implementation of patent-based and inventor-based relationships between scientific research and technical development within the context of regional or national systems of innovation.
