A deserted town once vibrant with active commercial activities around a railroad station now tries to find a way to escape from depression and revive its life with a renewed civic pride. An open space adjacent to the Main Street, the commercial district of Buzzards Bay, Massachusetts, is waiting to be transformed and reconfigured to be a new ecological park to boost the economy of the community. Bridge Park is 26-acre land abutting the Cape Cod Canal with a railroad bridge as a backdrop. The existing condition of the site with a small salt marsh, woodland, lawn, and the vestige of old railroad easement along with the proximity to the commercial district poses an interesting question of how to make a medium scaled ecological park within an urban context. This paper examines the winning design proposals for the Bridge Park submitted to the International Design Competition held in April, 2005. Six winning proposals were introduced and discussed in terms of categories related to the trend of contemporary landscape design such as; 1) ecological ordinariness and geometric figures, 2) topography and spatial imagination, 3) minimal programs and open put 4) time and process oriented design, 5) park and economic effects and 6) diagrammatic plan and photo montage. Bridge Park Design Competition confirms the complex characteristics representing the contemporary landscape design overcoming the dichotomy between nature and culture and the 'pastoral ecological design' and 'landscape as an art'. The Park becomes the activating agent for the community rejecting the conventional and passive role as a romantic picturesque landscape. Bridge Park International Design Competition is a meaningful event to test the idea of new ecological urban park, and to fine-tune the trend of the contemporary urban park design.

This paper proposes a compact-sized surface myoelectric sensor for myoelectric hand prosthesis. To fit the surface myoelectric sensor in the socket of the myoelectric hand prosthesis, the sensor should be a compact size. The surface myoelectric sensor is composed of a skin interface and a single processing circuit that are mounted on a single package. Since the skin interface has one reference and two input electrodes, and the reference electrode is located in middle of two input electrodes, we propose two types of sensors with the circle- and bar-shaped reference electrode, but all input electrodes are the bar-shaped. The metal material used for the electrodes is the stainless steel (SUS440) that endures sweat and wet conditions. Considering conduction velocity and median frequency of the myoelectric signal, we select the inter-electrode distance (IED) between two input electrodes as 18mm, 20mm, and 22 mm. The signal processing circuit consists of a differential amplifier with band pass filter, a band rejection filter for rejecting 60Hz power-line noise, amplifiers, and a mean absolute value circuit. We evaluate the proposed sensor from the output characteristics according to the IED and the shape of the reference electrode. From the experimental results we show the surface myoelectric sensor with the 18mm IED and the bar-shaped reference electrode is suitable for the myoelectric hand prosthesis.

Media manipulation of breaking news through article selection, ranking and tweaking of social media data and comment streams is a growing concern for society. We argue that the combination of human and machine curation on media portals marks a new period for news media and journalism. Although intermediary platforms routinely claim that they are merely the neutral technological platform which facilitates news and information flows, rejecting any criticisms that they are operating as de facto media organisations; instead, we argue for an alternative, more active interpretation of their roles. In this article we provide a contemporary account of the South Korean ('Korean') online news media ecology as an exemplar of how contemporary media technologies, and in particular portals and algorithmic recommender systems, perform a powerful role in shaping the kind of news and information that citizens access. By highlighting the key stakeholders and their positions within the production, publication and distribution of news media, we argue that the overall impact of the major portal platforms of Naver and Kakao is far more consequential than simply providing an entertaining media diet for consumers. These portals are central in designing how and which news is sourced, produced and then accessed by Korean citizens. From a regulatory perspective the provision of news on the portals can be a somewhat ambiguous and moving target, subject to soft and harder regulatory measures. While we investigate a specific case study of the South Korean experience, we also trace out connections with the larger global media ecology. We have relied on policy documents, stakeholder interviews and portal user 'walk throughs' to understand the changing role of news and its surfacing on a distinctive breed of media platforms.

Reducing plate-waste for school lunches is an important strategy to guarantee adequate nutrition intakes by students as well as to protect the environment. This study was conducted to determine dieticians' perception of no-plate-waste day. The subjects were dieticians at 203 schools in Seoul and Kyeonggi-do. Among them, 132 schools (78.6%) operated no-plate-waste day once a week, 6.9% once a month, 10.8% twice a week, whereas 17.2% did not operate at all. According to dieticians, plate-waste per student on no-plate-waste day (mean 49.1 g) was lower than that on an ordinary day (mean 79.2 g). The most popular method to advertise no-plate-waste day was to notify it on the menu board (52.4%), followed by notifying it on the dining hall and the school website. The most frequently used reward on no-plate-waste day was a gift snack (67.3%), followed by complimentary stickers, awards, and GPA. The most common side effect of no-plate-waste day was students' abandoning foods (45.2%), followed by rejecting food and simplified menu. The most frequent barrier was insufficient recognition of necessity (39.3%), followed by shortage of manpower or budget and students and teachers' resistance. The dieticians at 35 schools without no-plate-waste day answered that they did not operate it due to 'no need perceived' and 'no budget' (31.4% and 31.4%, respectively). Based on this study, government and society should promote the need to reduce plate-waste by students and teachers as well as school administrators.

The purpose of this study was to find and provide the prevention method by examining the Effects of Maternal Negative Behaviors and Children's Attachment Stability on Children's Aggression. The subjects were 339 children of fifth or sixth graders in Seoul. The questionnaires were derived and modified from Young Ae Park (1995) for the maternal negative behavior, Children's attachment stability from Ok Jung (1998) and Children's aggression from In Sun Jung(2006). The date were analyzed with descriptive statistics, t-test, F-test, Pearson's correlations and hierarchical multiple regression by SPSS 14.0 program. The major findings were as follows : First, the result showed there was average level of negative relationship when mother's negative behavior was compared with children's attachment whereas it showed average level of positive relationship in aggression. And also, low level of negative relationship showed between the attachment and aggression. Second, studying the influence it gives to the children's reaction and aggression after adding the children, parent and the family's popular social variables into the maternal's negative behavior, the outcomes showed the maternal's discipline and defiance upbringing had influenced the highest and tolerance, negligence was second high. This study mainly looked at the relationship between the maternal negative behavior with the children's attachment and aggression, but not like the nations pre.studied results, changes in human relation were examined with identifying the main several factors that bring greatest influence to the children's attachment and aggression. In conclusion, the children's attachment and aggression's the cause of the children's attachment and aggression were mainly from the maternal discipline and defiance upbringing. Based on this conclusion, it is essential for the maternal to have a sound discipline with right minds for endeavor to bring up the children with bring minds with less aggression and composed attachment.

본 논문에서는 최대 우도 (ML: maximum likelihood) 등화기를 적용한 협력통신 시스템의 성능을 분석하고 모의실험 하였다. 무선통신 시스템에서 통신 커버리지를 확장하기 위해서 다수의 중계기를 이용한 협력통신 개념이 적용된다. 중계기와 사용자 단말기는 모두 이동할 수 있는 것으로 가정한다. 따라서 두 개 이상의 중계기의 커버리지가 서로 겹칠 수 있다. 만약 원하는 신호와 간섭 신호가 동일 채널을 통해 전송되고 커버리지가 중복된 부분에 하나의 수신 단말이 존재한다면, 간섭신호로 인해 수신기의 성능은 열화된다. 따라서 본 논문에서는 통신 시스템의 성능을 향상시키고 간섭 신호의 영향을 제거하기 위해 최대 우도 등화기를 적용하였다. 협력통신 시스템의 성능은 비트 오류율 측면에서 평가되었다. 실험 결과로부터 최대 우도 수신기는 복잡도가 높지만 간섭 제거 성능이 우수한 것을 확인하였다.

포스트식민주의는 근자의 글로벌 사회 문화 현상을 설명하고 이해하는 데 중요한 이론적 자원으로 자리잡아 왔다. 문화가 갖는 보편성이나 초월적 진정성을 부정하는 포스트식민주의 이론은 근본주의적 가정을 벗어나 주체와 정체성이 재개념화되는 길을 열어 주며, 지리적 경계를 가로질러 부유하는 디아스포라의 혼종적 문화 경험을 통해 기존의 지배적인 문화적 상상과 사회관계에 대한 담론 질서를 전복시킬 수 있는 가능성을 그려 내기도 한다. 그러나 전 세계 문화의 차이와 다양성을 강조하는 포스트식민주의 서사는 변화와 재조정 과정에 있으나 여전히 강고하게 자리 잡고 있는 중심부와 주변부 국가들 간 불평등한 권력 관계 속에서 특정한 지역민들과 이주민들이 새로운 형태의 피착취 집단으로 구성되고 있는 현실을 제대로 조명하지 못하는 경향이 있다. 이 글의 목적은 포스트식민주의 이론이 전개되고 전유되어 온 과정에 대한 비판적 리뷰를 통해 지금 시기 글로벌 수준에서 발생하고 있는 부정의의 문제들을 보다 비판적으로 성찰할 수 있는 방안을 모색하는 것이다.

The purpose of study is to understand human-technology integration mechanism by using the study model that takes the core concept and motivation assumptions of technology acceptance model(TAM) into account. This study identifies three motivation mechanisms in adopting or using computer mediated communication(CMC) tool for work. The mechanism comprises with extrinsic, extrinsic motivation, and subjective norm pressure. One hospital with 430 beds and 367 human power was identified and we administered the questionnaire during their work hours. There is 32.4% response rate. The fitting index of the study model surpass the acceptable level, GFI = .980 for none-users, GFI =.986 for users, NNFI = .973 for none-users, and NNFI = .989 for users. In the case of none-users, perceived ease of use determines perceived usefulness that explains behavioral intention to use. As a result, adotpers' usage motivation is based on extrinsic motivation that does not consider their affective factor, attitude, in use of CMC. Users considers their attitudes as the mediating factor of all behavioral beliefs for using CMC continually. Thus, users are likely to depend their adoption behaviors on their affective factor. Moreover, users' behavioral intention is subject to pressures of use from other persons who are important to them, such as supervisor, director, or boss. Achieving human-technology integration in a hospital may cause cost saving and work efficiency. However, the success of information system should base on a profound understanding of employees' adoption behaviors in rejecting, adopting, using, continually using of IT, and organization culture in using IT.
