In recent years, many firms have built a good recruitment policy, focusing on the requirements set for candidates to meet the employers' satisfaction; they often have certain requirements for each accounting job's position. The study aims to identify and measure factors affecting the employers' satisfaction with accounting graduates in Hanoi, the important locus of firms' labor force. We conducted a questionnaire consisting of 16 observation variables with a 5-point Likert scale. Independent variables were measured from 1 "without effect" to 5 "strongly". Based on the literature review and results of interviews, a total of 150 questionnaires were sent to participants; 135 of them met the standards and were subject to be analyzed. The results of Cronbach's alpha, Exploratory Factor Analysis (EFA) and Multiple Regression Analysis (MRA) identify three main determinants influencing the employers' satisfaction with accounting graduates in Hanoi, including students' experience before graduating (SEG), reputation of universities (RU), and university's recruitment support policy (RSP). Based on the findings, some recommendations have been proposed to help universities design training programs for creating better satisfactions for employers in the future. On this basis, the authors propose a number of recommendations to improve the employers' satisfaction with accounting graduates in Hanoi.

Since the industrial revolution. the growth of cities has been especially apid and the rate of ulbanization has been high. This urban development is encroaching on the natural environment because the cities are developed with not only residential estates, industrial area and buildings but also with infrastructure. The surface area of the city is sealed ,with pavement whereas nature is disturbed and modified. The hydrological cycle in the city is inf1uenced by the change of land use I. e., from forest to agricultural land, talc draining of wetlands and above all the increase of built-up areas. The surface retention and interception of precipitation in the city is reduced. because the surface area is now smooth and solid. The characteristics of the hydrological cycle in the city are increased runoff, reduced evapotranspiration and infiltraction . We have too much faith in technology although it may cause more unforseen problems. We build more river banks and 'emulation dams and straighten rivers and streams in order to protect ourselves from disasters.. However. the results of hose developments are often higher$.$ water levels, the disturbance of aquatic ecosystems and the reduction of biodiversity. Therefore, we should examine problems from the hydrological cycle in cities and study a natural system as close cities to nature as possible. This paper shows the problems caused by the hydrological cycle in the city. The ecology-oriented method and design must be used in order to protect our environment from dicturbance.

Recently, our society is increasingly aware of the strengthening of 'publicness'. In particular, it is urgent to improve safety in that public spaces are used by an unspecified number of people. Therefore, the purpose of this study is to derive an indicators for evaluating crime safety in outdoor public spaces and to present the relative weights of each evaluation indicator. For this purpose, this study investigated the relative importance of crime safety evaluation indicators for outdoor public spaces to experts and conducted AHP analysis based on this. The result of this study is as follows. First, it was confirmed that similar tendency was observed among experts group (researcher, public officials, planner) related to outdoor public space. Therefore, the results of this study will be a certain reference point in the future social consensus on the issue. Second, the experts related to physical environment evaluation showed that the priority of environmental planning related to 'Natural surveillance' is highly evaluated in order to increase crime safety of outdoor public space. Next, it was recognized that 'Mechanical surveillance' and 'Legibility reinforcement' were needed.

This study aims to investigate the change in building density and residential environment after the reconstruction of decrepit public rental housing complexes formed in accordance with the Land Readjustment Project during the 1970s-80s. The results of this study can be summarized as follows: First, in terms of change in residential environment after the reconstruction, floor plans that were limited to two to four types and to small apartments measuring $42.9m^2$(13py)-$56.1m^2$ (17py) became varied, presenting 5-6 types of floor plans and various sizes of apartments. In particular, the reconstructed apartments were mainly built in a size smaller than 85($m^2$) and in the 3LDK floor plan and staircase-style unit architectural structure in order to reflect the lifestyle of residents. Second, in terms of change in building density after the reconstruction, the building coverage ratio did not change a lot, but the floor area ratio showed great change depending on the complex, ranging from a minimum of 2.9 times (Singdong Complex) to a maximum of 5.4 times (Eoyangdong Complex). Such change is attributable to the reconstruction policy that aims to improve the residential environment for original residents, secure economic feasibility and efficiency, and reflect the lifestyle of residents while incorporating dividends assigned to the existing housing project members as well as the maximum floor area ratio allowed by the regulation. Additionally, in terms of change in the number of floors and building density after the reconstruction, the former 5-story apartments were changed to apartments with 16-28 stories. Accordingly, the number of households in each complex has also increased by 20%. Third, according to the characteristics of parking facilities in terms of the size and density of parking spaces, former apartment complexes had only aboveground parking lots, not underground parking area. The newly constructed apartment complexes have underground parking space, and the parking-housing ratio is 1.1-1.3 cars.

Ships built today are larger in scale and feature more complex structures. The ever-evolving systems used on board a ship require vast amounts of data processing. In the future, with the advent of smart ships, unmanned ships and other next-generation ships, the volumes of data to be processed will continue to increase. Yet, to date, ship data has been processed using wired networks. Placed at fixed locations, the nodes on wired networks often fail to process data from mobile devices. Despite many attempts made to use Wi-Fi on ships just as on land to create wireless networks, Wi-Fi has hardly been available due to the complex metal structures of ships. Therefore, Wi-Fi on ships has been patchy as the ship-wide total Wi-Fi coverage has not properly implemented. A new ship-wide wireless network environment is part of the technology conducive to the shipbuilding industry. The wireless network environment should not only serve the purpose of communication but also be able to manage and control multiple features in real-time: fault diagnostics, tracking, accident prevention and safety management. To better understand the characteristics of wireless frequencies for ships, this paper tests the widely used TETRA, UHF and Wi-Fi and sheds light on the features, advantages and disadvantages of each technology in ship settings. The proposed deployment of a Super Wi-Fi network leveraging the legacy UHF system of TMS generates a ship-wide wireless network environment. The experimental findings corroborate the feasibility of the proposed ship-wide Super Wi-Fi network environment.

최근 소프트웨어 아키텍처 설계 시 소프트웨어의 재사용성 및 유지보수 비용의 효율성을 고려한 객체지향 디자인 패턴의 관심이 증가하고 있다. 따라서 본 논문은 객체지향 디자인 패턴 기반의 도메인 객체 인터페이스를 활용하여 특정 도메인에 해당하는 논문 투고 관리 시스템을 설계하고, 아울러 자바와 XML을 이용하여 구현한 시스템을 제안한다. 제안하는 시스템은 GoF 디자인 패턴을 적용하여 하향식과 상향식을 적절히 조합한 시스템 전체 아키텍처를 설계한 후에 상향식으로 각각의 시스템 객체들을 조립하여 구현하는 방식을 적용한다. 또한 본 시스템은 시스템의 데이터 자체에 대해서는 XML을 통해 각종 퍼시스턴스 객체(Persistent Object)의 형태로 변환되도록 하며, 도메인 객체를 클래스로 자동 생성하는 방식을 채택하지 않음으로써 시스템의 복잡성을 최소화한다. 마지막으로 시스템의 구현은 일반 클라이언트/서버 환경에서도 사용 가능하지만, 사용자의 편의성 및 일관성을 고려해 일반 웹브라우저에 내장된 XSLT를 통해 시스템 사용자 GUI를 구현한다.
