This study reviewed critically the music regulations of broadcasting advertising and analyzed the post reviews of Korea Communications Standards Commission(KCSC) to find their problems and suggest alternatives for their improvements. As general core regulations, lyrics changes of children's song is banned except in non-commercial public advertising and lyrics changes to folk songs are permitted unless it includes the product related expressions, such as brand name; both of their arrangements are permitted. According to the items, the lyrics of the CM song of drug advertising should not include its brand name; alcoholic beverage advertising is banned if the lyrics of the CM song include product-related brand name or an expression encouraging drinking. The rationales of these regulations of restrictions or prohibitions of music in broadcasting advertising are unclear and are insufficient. Therefore, it will be necessary to improve them based on the evidence or knowledge by more valid research in the future.

본 논문에서는 가장 최근의 동영상 표준인 H.264에서 가변 블록 움직임 예측 시 인접한 블록과의 상관성을 분석하여 병합 절차를 추가함으로써 매크로블록의 최종 모드를 결정하는 시간을 줄이기 위한 알고리즘을 제안한다. H.264에서는 매크로블록의 모드를 결정하기 위하여 총 7가지 모드를 사용하여 움직임 예측은 실시함으로써 부호화 효율을 극대화시킨 반면 이러한 움직임 예측이 부호화기의 복잡도를 높이는 주요 요인으로 현재 커다란 단점으로 지적되고 있다. 본 논문에서는 $8{\times}8$ 움직임 예측이 끝난 후 인접한 두 블록 사이의 거리론 임계값(Threshold)과 비교하여 다음 모드의 움직임 예측의 실시 여부를 먼저 절정함으로써 필요한 움직임 예측에 소비되는 시간을 단축시켰다. 여기서 실험 조건으로 명시하고 있는 것은 대표적인 단일모드 중에서 수행 성능이 가장 좋은 $8{\times}8$ 모드를 기본모드로 사용하고 병합 시 $16{\times}16$ 모드 쪽으로 상향식(bottom-up) 방법의 병합을 수행해 나아간다 모의실험을 통해 수행 성능과 전체 부호화 시간 측면을 본 논문에서 제안한 방법과 4가지 모드인 $16{\times}16,\;16{\times}8,\;8{\times}16,\;8{\times}8$ 모드를 모두 사용한 경우, $8{\times}8$ 단일모드를 사용한 경우를 비교하였다. 실험 결과 $8{\times}8$ 단일모드보다 수행 성능이 향상되었으며, 시간 단축 면에서 제안한 방법이 4가지 모드인 $16{\times}16,\;16{\times}8,\;8{\times}16,\;8{\times}8$ 모드를 모두 사용한 경우와 $8{\times}8$ 단일모드를 사용한 경우보다 계산 시간이 감소하였음을 확인하였다.행중인 MoIM-Messge서버의 네트워크 모듈로 다중 쓰레드 소켓폴링 모델을 적용하였다.n rate compared with conventional face recognition algorithms. 아니라 실내에서도 발생하고 있었다. 정량한 8개 화합물 각각과 총 휘발성 유기화합물의 스피어만 상관계수는 벤젠을 제외하고는 모두 유의하였다. 이중 톨루엔과 크실렌은 총 휘발성 유기화합물과 좋은 상관성 (톨루엔 0.76, 크실렌, 0.87)을 나타내었다. 이 연구는 톨루엔과 크실렌이 총 휘발성 유기화합물의 좋은 지표를 사용될 있고, 톨루엔, 에틸벤젠, 크실렌 등 많은 휘발성 유기화합물의 발생원은 실외뿐 아니라 실내에도 있음을 나타내고 있다.>10)의 $[^{18}F]F_2$를 얻었다. 결론: $^{18}O(p,n)^{18}F$ 핵반응을 이용하여 친전자성 방사성동위원소 $[^{18}F]F_2$를 생산하였다. 표적 챔버는 알루미늄으로 제작하였으며 본 연구에서 연구된 $[^{18}F]F_2$가스는 친핵성 치환반응으로 방사성동위원소를 도입하기 어려운 다양한 방사성의 약품개발에 유용하게 이용될 수 있을 것이다.었으나 움직임 보정 후 영상을 이용하여 비교한 경우, 결합능 변화가 선조체 영역에서 국한되어 나타나며 그 유의성이 움직임 보정 전에 비하여 낮음을 알 수 있었다. 결론: 뇌활성화 과제 수행시에 동반되는 피험자의 머리 움직임에 의하여 도파민 유리가 과대평가되었으며 이는 이 연구에서 제안한 영상정합을 이용한 움직임 보정기법에 의해서 개선되었다. 답이 없는 문제, 문제 만들기, 일반화가 가능한 문제 등으로 보고, 수학적 창의성 중 특히 확산적 사고에 초점을 맞추어 개방형 문제가 확산적 사고의 요소인 유창성, 독창성, 유연성 등에 각각 어떤 영향을 미치는지 20주의 프로그램을 개발, 진행하여 그 효과를 검증하고자 한다. 개방형 문

This paper focuses on the geographical pattern of financial activities in the Korean urban system during 1975-1990, based on the assumption that financial activities can reveal control points in Korea's urban economy. In terms of spatial evolution of financial insitutions, different locational characteristics are revealed among different types of financial institutions, implying the role of urban hierarchy. Financial resources are highly concentrated in the capital region, Seoul and Kyonggi Province. Both centralization trends into the large metropolitan cities and relative declines of medium and small cities within the Korean urban system, have been experienced over the study period. Financial activities sustain relatively stable hierarchical structure in the urban hierarchy. Regarding the financial flows, dominant flow zones centered on major metropolitan cities are identified, clearly showing a prominant role of Seoul in financial flows in the entire urban system.

Drawing on the autonomist Marxist concepts of 'social factory', 'immaterial labour', and 'precarity', this paper discusses the changed nature of labour, life and social relations in contemporary informational capitalism. More specifically, it first traces back to the early autonomist (operasimo) theories of 'social factory' and 'class composition' and then discusses how these earlier theories were developed into the concept of 'immaterial labour' by a group of later autonomist theorists such as Paolo Virno, Maurizio Lazzarato, Micheal Hardt, and Antonio Negri. Then, it reviews how the concept of immaterial labour was taken up to understand the nature of labour in digital economy within the tradition of Cultural Studies, closely intersecting with the critiques of 'creative labour'. Finally, it discusses how the changed nature of labour is interrelated with the neoliberal labour forces transformations such as casualization of employment and increasing insecurity in employment and life, which the autonomist explores with the concept of 'precarity', the material condition of immaterial labour.

Low fertility has become quite commonplace worldwide, and Europe has experienced below replacement fertility for several decades. In addition, lowest-low fertility, defined as period total fertility rate below 1.3, has rapidly spread in Europe during the 1990s and is likely to expand further. After the turn of century, lowest-low fertility started spreading in Eastern Asia. Korea's TFR of 1.19 in 2008 is lower than most European countries, although it is higher than the Hongkong(1.02) and Taiwan(1.09). The purpose of this paper is to examine the socioeconomic determinants of lowest-low fertility in Korea. In doing so, this paper discusses the effects of female labour force participation, labour instability on family formation and fertility. The data includes female labour force participation rate, unemployment rate, age at first marriage, and total fertility rate from 1980 to 2008. First, the economic recession hindered young people's economic independence and propensity to marry. Married couples were also depressed with uncertainty toward the future and avoided to have children. Second, the growth in female labor force participation had a negative impact on fertility, under the low level of compatibility between women's work and childrearing. Moreover, this paper argues that the rising cost of children including public and private educational costs is thought to be the main reason of the recent low fertility in Korea. Policy implications and some comments on population policies are also presented in the final section.

The utilization of Building Information Modeling (BIM) has increased in order to enhance the integration of information for management and resources throughout the construction projects. Therefore, various BIM softwares have been used under open BIM environments in the building and plant construction industry. However, it has obstructive factors due to the lack of interoperability. In order to address this problem, this study conducted an interoperability analysis of BIM software focused on user-defined properties for enhanced function and efficiency. Result of the analysis shows that authoring tools have more interoperability problems than viewer tools and simulation tools have. In terms of interoperability, user-defined properties outperforms than those of system basic properties and logic data. Therefore, it was found that functional improvement and workload minimization in BIM can be attained by applying the GBS (an user-defined property for automatic manipulation of BIM proposed by Jung et al. 2013) that enables automatic link between geometric data and non-geometric data. In this respect, this study concludes that the application of user-defined property (e.g. GBS) can be an effective method for information integration throughout construction projects.

Neoliberalism became a catch word of a post-cold war era. It began to develop in the middle of welfare state crisis in developed countries. It promoted both a unified world market through mutual penetration of national boundaries in International scene and maximization of efficiency through market competition in domestic scene. Privatization of public corporations is a major policy to pursue market efficiency through deregulation. Two reasons are often adduced to support the cause The socio-economic changes diminished the necessity to establish public corporation on the one hand. On the other hand gross inefficiency has been observed in the management of public corporation. 'Government failure' is an apt expression of the inefficiency. In analysing the experiences of privatization of utility industries of some other countries we found a couple of lessons for a Korean case. First, it is doubtful if privatization, that is a change in the form of ownership, is a necessary condition for achieving market efficiency. Because it is possible to operate a mechanism of market competition while maintaining competition among public corporations and with private actors. Second, the patron-agent dilemma is often cited as a major culprit of an inefficient management of public corporations. But it is without saying that the dilemma is also found in the management of private firms. So, the issue is not the privatization per se but to realize responsible management through discipline and incentives.

As the mobile telecommunications industry in Korea boasts record-high revenue from its businesses, consumers and other industries are looking for new business applications and opportunities using mobile technologies. Many firms are seeking guidelines or business models for an effective use of this new mobile technology in their operations. This paper reviews the characteristics that distinguish mobile marketing, and analyzes marketing approaches which utilize the potential of the new mobile technologies. This paper shows that the new mobile advertising channel is not only complementary to traditional marketing channels, but also delivers benefits for multiple parties involved in mobile marketing. The key success factors in the new OB (Oriental Brewery) marketing campaign include a shortening of the stages in the AIDMA model and a broadening of customer contact points by exposing the brand through well-coordinated marketing efforts. The OB case shows that a mutually beneficial relationship between co-marketing participants can lead to a win-win marketing strategy. It also highlights that collaborative channel management in mobile marketing methodology is critical for successful mobile marketing.

The purpose of this study was to examine the flow of teacher-student verbal interactions and the types of discourse in the science gifted classes of three effective teachers. The three effective teacher were recommended by the expert of a gifted education or science education expert. A participant observation was carried out in their classes, and all the classes were videotaped. The collected videotape materials were transcribed, and Flanders Interaction Analysis Categories and an AF program were utilized to analyze the video clips. The findings of this study were as follows: First, there was no specific flow of verbal interactions in the classes provided by the effective gifted teachers, but the kind of positive verbal interaction that the students responded diversely to their questions or lectures took place. Second, the most prevalent type of utterance in the classes of them was lecturing, and the remark of direction and criticism scarcely took place. And lots of non-directive remarks were found such as emotional acceptance, praise, encouragement or acceptance of ideas. As a result, the effective science gifted teachers made more nondirective remarks such as emotional acceptance, praise, encouragement and acceptance of ideas than directive remarks such as direction or criticism, and their non-directive remark made it possible to elicit more extensive responses from their students.

A series of analysis and experiment on the fishing gear and method of the existing midwater pair trawl net with 12,800mm of maximum mesh size is carried out to determine the most effective shape factor. As the first step of this study, the fishing gear and method for the existing net are analyzed to solve problems, such as being low of the net height by increasing the towing speed, twist of net pendant and twine, suspension of float between knots of mesh. etc. Standing on these results, the existing net are modified by very effective shape based on the theory and technology designing the fishing gear. Also, the model experiment is carried out to determine the most effective shape factor of the modified net in the circulation water channel. The obtained results can be summarized as follows : 1. On the length of net pendants(No.2 and No.3) connected with side line, opening efficiency of net with length 8.0cm of net pendant is the greatest and in the order of 11.5cm, 15.0cm. 2. On the number of the net pendant, opening efficiency of net with 4 lines of net pendant is the greatest and in the order of 3 lines, 2 lines. Center part of side panel is pushed out backward, and the pushed length is increasing by increasing flow speed. 3. On the sinking force, opening efficiency of the net is increasing by increasing sinking force. And opening efficiency shows almost the same when sinking force is greater about 1.5 times than that of the existing net in case of the net with 3 lines of net pendant, and about 1.6 ~ 1.7 times than that of the existing net in case of the net with 2 lines.
