Construction machinery includes an engine enclosure separated from a cooling system enclosure by a wall to reduce noise and advance cooling system performance. For this structure, however, the axial fan cannot be of benefit to the engine room, and so the temperature rise in the engine room makes several bad conditions. This paper proposes that hot air in engine room is evacuated tv secondary pipe using jet pump. This paper demonstrates the structure and the effect of jet pump and useful guideline on design of area, length, and shape of secondary pipe to maximize the effect of jet pump.

Because of the airtightness of building, misuse of building materials and abuse of furniture, indoor air pollution problems have been increasingly concerned especially with apartment buildings. To improve the IAQ(Indoor Air Quality) in apartment building, this study was aimed at analyzing the factor of interior building material and furniture and calculating the ventilation rate of living room and bed room according to the surface area of interior building material and furniture in terms of VOCs(Volatile Organic Compounds) and HCHO(Formaldehyde). The results of this study are as follows; 1) In the concerned rooms, the living room has less pollution emission rate L(surface area/volume) than that of the bed room but, the living room needs more ventilation rate than that of the bed room because of built-in furniture in terms of VOCs and HCHO. 2) Built-in interior furniture is very important factor in IAQ problems of apartment building, but until now there is no provision about the built-in furniture, so that the provision must be regulated to control the IAQ. 3) To control the IAQ problem, the effective ventilation plans must be established according to the required ventilation rate by means of natural or mechanical ventilation method.

Purpose: This study aims to examine spatial characteristics of ambulatory care department Chronologically through case studies; and to consider the social implication of these spatial changes. Methods: In this study, a total of eight ambulatory care departments, one or two for each period, were selected in order to analyze the spatial characteristics. Results: First, since the 1990s, the outpatient department of the US has been changed into a patient-centered space by providing high quality outpatient medical services through individual exam room planning. Second, the exam room has been changed from open/semi-open/group exam room to individual exam room since 1990, and the trend is shifting from the cluster type to the modular type consisting of universal exam rooms in order to achieve the flexibility of exam room. Third, the diagnostic/testing area has been deployed to the ambulatory clinic to enable 'one-stop shopping' for patients-centered care since 1990s, however, it has been disappearing since 2000 due to Reduce medical expenses. Fourth, the Central Nursing Station type first appeared in the outpatient department In the 2000s, followed by the type of decentralized nursing station type since 2010s. And fifth, the area of medical support has been placing to be concentrated on one place due to the Lean Design strategy since 2010. Implications: In the future, it is expected that Korea will be more focused on efficiency, visual control, and flexibility in the planning of the ambulatory care department as in the case of the United States.

Purpose: To establish guidelines for local public hospitals, the survey was conducted primarily on the current status of local public hospitals, focusing on the zone configuration and the spatial area of the operating department. Methods: 3 Methods have been used in this paper. 1) Analyzing drawings to derive the net floor area of each room. 2) A literature survey about composition of the zone by infection control. 3) Observation survey for user circulation analysis. Results: The operation department consists of the major, secondary, support and connected zones according to the user's actions. The spatial area composition ratio for each zone is major zone: 41.79%, secondary zone: 10.87%, support zone: 23.10%, and connected zone: 24.24%. Implications: This study is a basic research for guideline for the operation department in local public hospitals. In this study, zones configuration of the operation departments are classified in terms of user actions and room functions. In the future, it is required to establish criteria considering infection control and copper connection aspects.

The purpose of this study was to investigate using behavior and spatial composition of activity room in skilled nursing facilities for the elderly and to provide basic information about its space planning. The design guidelines for activity room were as follows. First, the plan of activity room is based on the use of once to twice per week and for 30 minutes per use, and is mainly for the human knowledge and art programs. Second, all cases of the same and different floor of the individual room could be considered as its location. Third, the area is recommended at least more than 6 square meters per person including participating elderly, staff, furniture, equipments and restroom. Fourth, the furniture of activity room include the shelves, table for at least 8 persons with enough knee space, wheel, and stack chairs. Toilets and water closet should be arranged for the emergency, and the windows to the hall and curtain door need to be avoided for soundproofs and easy accessibility of wheelchair users.

Based on theories and case analysis, the present research concerns the deduction of useful results about the basic stage for setting up a planar plan for children's play therapy facility, which cures children's psychological problems such as social maladaptation by means of play rather than language. The case analysis was sub-categorized into movement in each area, relative position among areas, and the size of each room. Detailed investigations were made concerning: First, Adjacent areas of each area. Second, Movement plan, which was sub-categorized into the movement of therapists and that of the children receiving therapy and guardians; area was sub-categorized into management area, therapy area and service area. Third, the size of each area measured was calculated to be expressed as the percentage of the total size. The result is as follows: (1) As for adjacent areas, in some cases management area and service area were adjacent, with isolated therapy area; whereas in the other cases, service area and information area, which is a part of management area, were placed along the doorway, with therapy area between them and therapist area, which is the other part of management area, behind them. (2) As for movement, the movement of therapists and that of children receiving therapy were same; whereas the movement of guardians was allowed only up to the middle part of the therapy facilities, and there was almost no entry of guardians into the play therapy rooms located in the inner parts. This is because they do not show the details of their therapy for children to guardians. (3) As for size, the area of independent facilities were similar; whereas institutional facilities in general had larger waiting room and unlike independent facilities, were of diverse size.

As ecological design elements, daylighting can be applied to provide adequate illumination on visual tasks to create an attractive visual environment and to save electrical energy. Daylighting control systems reject direct sunlight and penetrate it onto the ceiling or to deep into the room. This study aims to evaluate the luminance environment of sloped light guide with automated venetian blind systems according to sun angle changes. For evaluation, a mock-up model was used and the south facing side-window mounted between the clerestory window and the view window. To assess luminance performance, 3 view points of luminance were monitored. As results, the conventional and lightshelves show ideal luminance ratio between workplane and surroundings(3:1) and workplane and darkness area(2:1) due to total ratio of surroundings and darkness area has lower ratio than workplane. Compared to the lightshelves window, conventional window shows unrelieved effect in between the workplane and brightness area(1:5). It means that there has low deviation according to the required standards. Also, compared to the ratio between the brightness area and darkness area(2~6:1) conventional window with high deviation(10~20:1) provide discomfort glare due to the excessively strong contrast, while lightshelves window shows a required luminance ratio that provide a three-dimensional effect to occupants. Therefore, luminance distribution indicate that application of a lightshelves and blinds not only has a significantly positive effect but also offers higher luminance quality in a daylit room
