철도차량기지 중정비 공장의 규모를 설계할 때 최소 부지에 시설을 배치하여 검수효율을 향상시킬 필요가 있다. 본 연구에서는 중정비 공장 규모 산정 시에 적용되는 운행과 검수의 파동요인을 고려한 파동율(이하 "여유율")이 국내에서 아직 검증되지 않은 채 활용되는 외적인 요인을 중정비공장내 재장시간으로 흡수하기 위해 시설배치도 및 공정 작업의 시뮬레이션 분석에 의하여 합리적인 여유율을 산출하고 그 적정성을 검토하고자 한다. 본 연구는 공정의 작업시간이 평균값으로 되어있어 작업자 간의 편차를 고려, 공정작업시간에 표준편차를 10~20%로 주어 각각의 경우별로 시뮬레이션 결과치를 분석하여 가능 여유율을 도출하였다. 향후에는 차량의 운영 및 검수계획, 차량 예비율 및 중정비 공장의 설비능력, 공정외주비율, 표준인공 등 운영조건 등의 인자를 고려하여 과학적인 검토를 통해 적정 여유율을 적용함으로서 공장 규모를 최적화 할 필요가 있다.

스마트폰에는 다수의 응용 프로그램들이 탑재된다. 이 응용 프로그램들의 탑재, 삭제, 배치 등을 관리하는 서비스 응용 프로그램을 런처라고 하며 다양한 런처들이 사용된다. 기존 런처들 중에서 응용 프로그램의 사용자 활용 패턴들을 분석하여 아이콘을 자동으로 배치하는 기능을 제공하는 것도 있다. 본 논문에서는 스마트 폰 화면에서 아이콘들이 균형을 이루도록 아이콘을 자동으로 배치하는 방식을 제시한다. 사례를 통하여 이 방식의 자동 배치가 사용자에게 유용함을 보였다. 이 경우 높이가 m이고 너비가 n인 m × n 화면 레이아웃에서 n이 홀수이면 전체 화면이 n 값과 관계없이 항상 균형을 이루도록 배치할 수 있음을 수학적 귀납법으로 증명하였다.

The purpose of this study was to develop a personalized SMT (smart monitor target) game interface for game users who enjoy airsoft sports as individual purchases of SMT have increased since the advent of the untouched era. For this study, the UX (user experience) of the game interface was designed based on previous research. In particular, the personalized game service was reinforced by adding the CP (command post) of the SMT system that performs the home function of the console game, which was intended to help the user maintain immersed in the game in the personalized space of the SMT. Major design elements for the SMT game interface included layout, color, graphics, buttons, and text, and the interface design was proceeded based on them. After composing a grid with a layout in which the tab function was applied to the interface with a vertical three-segment structure and the outer margin value secured, the military camouflage pattern and texture were applied to the colored tone to perform graphics work. Targets and thumbnails were produced as illustrations using experts to ensure the consistency of the interface, and then function buttons and texts on each page were used concisely for intuitive information delivery. The design sources organized in this way were developed using the Unity engine. In the future, we hope that game user-centered personalized interfaces will continue to develop and provide differentiated services unique to SMT systems in the airsoft gun market.

Menu is regarded as the main factor for management of hotel and restaurant. Menu design was affected by many factors, but there are some items should be considered carefully for development of menu, such as a good understandings of consumers' demand. considering of the regional characteristics, establishing of the exact target, and careful thinking of a unit cost. At last, the most important factor is careful evaluation of developed menu and it have to be continuously reformed by feed back of these factors. Food service industries should create an independent menu(including restaurant layout, consumer level, marketing and advertising) rather than copying other restaurant' menu. Also. we have to design an efficient menu with useful information through the best of menu.

We address the problem of designing a physical CATV network with switched-star topology in which the broadband interactive service is provided. There are two types of decision variables: One is where to place conduit paths, and the other is how many cable units to be installed on each link traversed by an established conduit path. Due to the serious drawback of the conventional approach partitioning the problem into two subproblems, the unified approach handled in one setting is used here to attack the whole problem without dividing into two ones. In this paper, we present a mathematical design model and propose an efficient solution method exploiting the nice structure of it. In addition to this physical design, some results on logical network configuration have also been made. Finally, computaional experiments are conducted to illustrate the efficiency of our design approach.

새집증후군과 같이 실내공기의 오염은 최근에 많은 관심을 갖는 영역중 하나이다. 이 오염을 제거하는 효과적인 방법중의 하나가 친환경적인 식물의 공기정화 기능을 활용하는 것이다. 이러한 식물들은 잎사귀를 통하여 오염물질을 흡수하며 동시에 음이온을 발생시켜 실내환경을 개선시킨다. 여기서는 건물의 공기오염원에 따른 적절한 식물의 선택, 배치, 및 관리정보를 제공하는 실내공기정화용 정보시스템에 대하여 기술하고자 한다.

This study is for getting sacrificial service, discussing process of sacrificial rituals and understanding the composition of space in Dong-gok Jaesa. For these things, we're arranged for exact blueprint through actual survey and analyzed the architectural features. Dong-gok Jaesa has features which show centripetal space organization with strong closing sparsely. This is intended for sincerity during ritual which is processed without obstruction. This is a mixed form which is unified both straight dwelling and Jung Dang Hyeop Sil type. And this is for all functions which is necessary for Jaesa architecture in only one building. And this is used with organizing technique for space utility with connection of compartments and various enlargement and partition. Through these things, even though it is not a big Jaesa, it shows that this is Korea traditional composition of space technique according to several purposes.

The spreadsheet Microsoft Excel is the most widely used mathematical tool in today's workplace. Moreover, it is also an outstanding means for developing a surprisingly wide range of creative and innovative educational uses within such areas as mathematical modeling, visualization, and instruction. The spreadsheet's format provides us with a tool that closely parallels the way in which we naturally carry out problem solving, while the spreadsheet creation process itself illuminates the underlying mathematical concepts. In addition, the spreadsheet's visual layout allows us to introduce a broad variety of challenging and interesting topics, and to design creative demonstrations through eye-catching animated graphics. The material presented comes from actual classroom mathematics teaching experience in both industrially advanced and developing nations. A series of highly visual interactive illustrations from mathematics, the natural and social sciences, computing, engineering, and the arts provide a number of usable examples. The material discussed is applicable at diverse levels, ranging from schools and universities through adult education and in-service teacher development programs.

Experiments were carried out to investigate smoke movement in platform of a subway station which currently is in service in Pusan, the second largest city in Korea. The recently constructed underground station of the "bank type" (two platforms on both sides of track) which is the popular layout of platforms in Korea, is chosen in Pusan. The smoke generator and heater are used for simulating the smoke movement at the fire break in the platform located in the 2nd basement of the station. Video recordings were used to monitor smoke lowering. In this study, the movements of smoke in the underground station are investigated under various smoke-control operating modes. Three tests wire conducted according to its operating mode of the ventilation systems in the platform: no operation of any ventilation systems, smoke extraction mode in occurrence of fire (presently running mode) and full capacity of smoke extraction where all vents are activated in the platform. The results can be used for comparing with the numerical prediction results of fire subway stations.
