Recently, ITU-T recommends that FlexE, which allows the flexible configuration of Ethernet signals, be received by OTN for transparent transmission through OTN. To compensate for the difference in bit rate that can occur when mapping FlexE signals to OTN payload, an idle codeword is removed or inserted. However, the detailed functional blocks required to implement this method are not yet available. In this paper, based on the recent ITU-T requirements, a detailed functional block for OTN mapping of FlexE signals is proposed based on 400G class. In addition, based on the detailed functional blocks, mathematical analysis was performed to obtain the characteristics of removing and inserting idle code words, and the simulation results are shown.

This study investigates the space, use, and procedural aspects that should be considered in securing the publicity in space renewal of unused lands by analyzing the characteristics of relevant projects conducted by The Korea Academia-Industrial Corporation Society, a party representative of a public agent. The findings reveal the following conclusions. 1. There should be a required procedure that guarantees the adequate qualities of public organizations or publicity for projects run by KAMCO. 2. When the public agent plans a project, there should be an effort to clarify the profit limitations and adequate guarantee of consigned fees charged by the consigned organizations in an attempt to ensure that certain proportions are used to enhance the public goods. 3. There is a need to diversify the ways KAMCO discloses information. A professional organization and separate budget should be required to assess the autonomy of KAMCO to guarantee publicity.

The rapid growth of mobile-based online shopping and the appearance of untact business initiated by COVID-19 has led to an explosive increase in demand for logistics services such as delivery services. In order to respond to the rapidly growing demand, most logistics and distribution companies are working to improve customer service levels through the establishment of a full-filament center in the city center. However, due to social factors such as high land prices and traffic congestion, it becomes more difficult to establish the logistics facilities in the city center. In this study, it has been proposed the way to choose the candidate locations for the shared distribution centers among the space nearby the tall-gate which can be idle after the smart tolling service is widely extended. In order to evaluate the candidate locations, it has been evaluated the centralities of all candidates using social network analysis (SNA). To understand the result considering the characteristics of centrality, the network structure was regenerated based on the distance and the traveling time, respectively. It is possible to refer the result of evaluation based on the cumulative relative importance to choose the best set of candidates.

Mobile IP provides an efficient and scalable mechanism for host mobility within the Internet. Using Mobile If, mobile nodes may change their point of attachment to the Internet without changing their If address. However, it would result in a high signaling cost. To reduce the signaling cost, we factor in the fact that mobile users will not be actively communicating much of the time. In fact, there Is no necessity to send a binding update message to the home agent when an mobile node does not communicates with others while moving. From this point of view, we propose a lazy update strategy for minimizing signaling cost using the forwarding pointer in hierarchical Mobile IPv6. In our proposal, binding updates are sent only when a mobile node is in a busy mode. If an mobile node is in a dormant mode, binding update messages are delayed until busy mode using the forwarding pointer. As a result, our proposal can reduce the total signaling cost by eliminating unnecessary binding update messages when a mobile node Is in a dormant mode. In addition to, our proposal reduces unnecessary location update cost resulting from ping-pong effect under mobile node's dormant mode. Analysis results using the discrete analytic model presented in this paper shows that our proposal can has superior performance than hierarchical Mobile nv6 when the call-to-mobility ratio is low and the length of the forwarding pointer chain K is low.

도시에는 다양한 종류의 기반시설들이 있고 이들은 계획방법에 따라 건축적으로 활용될 수 있는 가능성도 충분히 가지고 있다. 기반시설의 건축적 활용은 가용지가 부족한 도시에서 유휴공간으로 방치될 수 있는 도시 내 잃어버린 공간을 재생시킨다는 의미도 가지며 공공시설의 통합디자인이라는 측면에서도 중요하다. 본 연구는 이 점에 주목하여 도시 내 기반시설 중 교통관련 시설인 교량, 도로, 교통섬 등을 활용하여 공공공간을 계획한 사례들을 중심으로 계획특성을 고찰하고 시사점을 도출하였다.

Along with changes in the industrial structure, revitalizing decrepit or abandoned industrial-age infrastructures are actively under way on a global scale. This study was motivated by an interest in investigating currently idle industrial infrastructures and revitalizing the abandoned passenger ferry terminal in Geoje's Jangseungpo and surrounding areas. The main aims of this study were to examine regional features for the purpose of establishing urban renewal plans and field opinions of the local residents on how to proceed with the restoration of the passenger ferry terminal. To this end, this paper looked into previous case studies of converting decrepit industrial infrastructures into new cultural venues, depending on each region's special circumstances. This paper's findings are as follows: First, as a result of this investigation, the author found that in all cases in Korea and elsewhere revitalization focused on creating modern cultural spaces appropriate for the region while retaining its traditional value. At the same time, they sought sustainable cultural and economic revival. Second, as a result of the investigation on Geoje City's local characteristics, the author found that the surrounding areas' commercial districts were depressed after the terminal's closure. At the time of the investigation, the city government was trying to reopen the terminal as a major port offering multiple international ferry destinations while attracting tourists. Third, as a result of the surveys on the local residents, it was found that more than half of the residents were in agreement with the city government's plan to reopen the terminal and expressed their wishes that they want the terminal to have other uses such as cultural venues. Based on these research results, the author makes proposals, including expanding the passenger ferry terminal and offering cultural spaces within and near the terminal, based on the local residents' opinions and in reflection of local circumstances. As part of this effort, the author also recommends a new brand name and design plan for the new passenger ferry terminal so that Geoje City can improve its local community value.

The survey of birds in Nakdong River Basin was conducted from March in 2003 to February in 2004. This study shows that the population of birds was 94,481 individuals and 114 species. The bird recorded in Daemadeung (Ⅰ) was 21,781 individuals and 55 species. It is surrounded with silt to have a better condition for a habitat and the rest place than other areas in the Nakdong River Basin. In the traits of the groups, Grebes were well established in the lower estuary(Eulsook islet), Cormorants in the main stream of the Nakdong River and around West Nakdong River (F). Swans, Shelduck and Shorebirds were using silt in the lower estuary where the depth of water is shallow, dabbling ducks were also established in West Nakdong River (F) and Yummak (C), diving ducks in the upper Nosan Watergate in West Nakdong River (F). Besides, land birds was distributed in the Yummak (C), Eulsook islet (A) and West-Nakdong River (F). Because they are connected with the artifical forest in Eulsook Islet Garbage Field and Ⅱwoong islet, it is good for the land birds and the water birds to have a habitat in this kinds of vacant lot. The Nakdong River Basin is not only an important area as the habitat and rest place for ducks and geese but also one of the areas where we can not get out of the temptation to development. To preserve effectively the natural habitat from human s intervention, it needs to keep supervising in Daejeo Watergate (E) and the upper area Noksan watergate in West Nakdong River (F) and Yummak (C).
