Point of interest (POI) of the city is a special place that has what importance to the user. For example, it is such landmark, restaurants, museums, hotels, and theaters. Because of its role in the social and economic life of us, these have attracted a lot of interest in location-based applications such as social networks and online map. However, while it can easily be obtained through the Web, the basic information of POI such as geographic location, another effort is required to obtain detailed information such as Wi-Fi, accepting credit cards, opening hours, romper room and the assessment and evaluation of other users. To solve these problems, a new method for correcting position error is required to link location-based social network service (LBSNS) data and POIs. This paper attempts to propose a position error correction method of POI and LBSNS data to enrich POI information from the vast information that is accumulated in LBSNS. Through this study, we can overcome the limitation of individual POI information via the information fusion method of LBSNS and POI, and we have discovered the possibility to be able to provide additional information which users need. As a result, we expect to be able to collect a variety of POI information quickly.

This study attempts to investigate the spatial characteristics of medical hospital distributions in Korea. For the purpose we examine the inter- and intra regional variations in the distributions of clinics by specialty subject. In particular, we analyze the distribution patterns of Location Quotients of clinics for 12 specialty subjects in Seoul. Medical services tend to be concentrated on the large cities, especially in the Metropolitan Seoul Area. In particular, clinics and medical doctors as well as large scale general hospitals have been strongly concentrated on the Metropolitan Seoul area. These circumstace may be related with the fact that medical hospitals are established and operated by private sector in Korea, and thus they attempt to find their location where they can get maximum profit. The distribution patterns of clinics of 12 specialty subjects can be classified to several characteristic patterns. In particular, clinics of plastic surgeon tend to be strongly concentrated on the Gangnam area in Seoul. Finally, clinics of plastic surgeon tend to be located on the areas near the subway stations along the subway Line 2 and Line 3 in the beginning. The existence of plastic surgeons turns out to have significant role on determining the location for the newly opening plastic surgeons in the later. Therefore, their agglomeration has been getting more strongly.

The current study proposesto examine the external appearance types of urban-style hanok in the Bukchon Hanok Preservation District according to their use. For this purpose, we conducted a field survey from the 12th of September to 10th of October 2005, which investigated the location, condition md use of urban-style hanok that were being used for non-residential purposes. The external elevation of the houses were observed and photographed. The results are as follows. First, there were 158 urban-style hanok used for non-residential purposes and200 cases of non-residential use. There were 69 cases of food and beverage spaces, 58 cases of small retail businesses, 38 cases of cultural facilities and 7 cases of convenience facilities. Second, among residential urban-style hanok used for non-residential purposes, 131 cases changed the external appearance of existing urban-style hanok and only 69 cases maintained the original appearance of urban-style hanok or renovated the appearance fittingly to non-residential use. Among the renovated cases, 59 involved the construction of a firewall and 10 cases involved remodeling in a contemporary style. Among the transformed cases, 40 cases exhibited a full opening to the roadside, n involved the change of external appearance components, 14 involved the extension of the courtyard and 12 involved overall improvements to a contemporary style. Third, in the case of cultural facilities and offices, many instances reproduced an urban-style hanok in the traditional style, but small retail shops and food/beverage spaces showed serious deformation. Particularly small retail shops opened the side to the road or extended the courtyard regardless of the location of the houses in order to increase the store space and, as a result, severely damaged the urban-style hanok. In addition, many food/beverage spaces remodeled their external components using tiles, bricks or metals, which were easy to maintain.

The effects of changes in area and location of fire source, fire growth rate, and volume of compartment on the major fire characteristics, including heat release rate, in closed compartment fires were examined. To this end, a fire simulation using Fire Dynamics Simulator (FDS) was performed for ISO 9705 room with a closed opening. As main result, it was found that the changes in the area and location of fire source did not significantly affect the thermal and chemical characteristics inside the compartment, such as maximum heat release rate, total heat release, maximum temperature at upper layeras well as species concentrations. However, increasinthe fire growth rate and volume of compartment resulted in increase of the maximum heat release rate and total heat release, decrease in the limiting oxygen concentration and increase in the maximum CO concentration. Finally, a methodology for the application of fire growth curves to closed compartment fires was proposed by deriving the correlation of the maximum heat release rate expressed as a function of the fire growth rate and the volume ratio of compartment based on the ISO 9705 room.

It is necessary to develop a new location model to support the application of smart technology and confluence in the 4th industrial revolution era. In this study, we propose 'network-type industrial complex' as a method to link several industrial integrated spaces which are dispersed in an area. As a result of conducting a survey of companies in order to develop a new location model, about 89% of companies recognized the necessity of network-type industrial complex. As a condition for activation of the industrial complex, 'complementary function formation', and 'convenience of nodular transportation' were selected. It is expected that it will be possible to supply low-cost, high-efficiency industrial complexes through opening and linking with urban space and infrastructure sharing.

This study discusses a hypothetical method for tracking the propagation damage of Carbon Reinforced Fiber Plastic (CRFP) components underneath vibration fatigue. The High Cycle Fatigue (HCF) behavior of composite materials was generally not as severe as this of admixture alloys. Each fissure initiation in metal alloys may quickly lead to the opposite. The HCF behavior of composite materials is usually an extended state of continuous degradation between resin and fibers. The increase is that any layer-to-layer contact conditions during delamination opening will cause a dynamic complex response, which may be non-linear and dependent on temperature. Usually resulted from major deformations, it could be properly surveyed by a non-contact investigation system. Here, this article discusses the scanning laser application of that vibrometer to track the propagation damage of CRFP components underneath fatigue vibration loading. Thus, the study purpose is to demonstrate that the investigation method can implement systematically a series of hypothetical means and dynamic characteristics. The application of the relaxation method based on numerical simulation in the Artificial Intelligence (AI) Evolved Bat (EB) strategy to reduce the dynamic response is proved by numerical simulation. Thermal imaging cameras are also measurement parts of the chain and provide information in qualitative about the temperature location of the evolution and hot spots of damage.

In this paper, we investigate several factors that affect the locational decision of discount stores by using previous studies on the marketing area and the location of commercial facilities. We selected 21 primary variables that are expected to influence the decision of store location and, by factor analysis, grouped them into five underlying factors. Among these, the demographic factor, which shows the potential purchasing power level, had the greatest impact on the locational decision for the store. However, we found individual stores positioned according to unique locational characteristics in addition to the demographic factor. It means that we have to additionally consider if the vicinity of the market is based on any physical properties. Many previous studies proposed four decision factors for store location: the economic factor, the demographic factor, the land utilization factor, and traffic factor. However, the fivefold factors-our distinctive contribution-are more concrete and persuasive according to Korean reality. We show that location preference is based on the following criteria: (1) the area is densely populated, (2) houses stand close together, (3) residents have a high income level, (4) road traffic is developed and easy to access, and (5) public transportation is well developed. The demographic factor has the greatest impact on the location of a discount store. The number of households has a greater relevance to the demographic factor than does the individual consumer. Second, discount stores relatively prefer places where houses are located close together because such places offer easy access to the market. Third, a place whose residents have a high income level will be preferred, with its large cars and excellent traffic conditions. Fourth, a location would be highly rated if the roads around commercial facilities are well developed and their accessibility is good. Finally, discount stores must be located close to bus stops because female consumers, including housewives-the most important customers-evaluate stores based on distance. In this research, the variable of consumer attitude and preference was excluded, and the location factors of discount stores were analyzed according to a microscopic view through physical spatial data. In the future, the opening of new discount stores based on the five factors indicated above will require a comparatively shorter time from the first project feasibility analysis. In addition, the result of our study can be applied to the field of public policy for constructing and attracting large-scale distribution facilities.

The multipurpose auditoriums in schools are the center of local community and the places of their life-long education. The multipurpose auditoriums are to be open and made available for use by local public as far as it does not interfere with the education of the schools. However, most of them are not open to public on the pretext of management problems while demands of local communities for the opening of the facility is rising. The role of the multipurpose auditorium as the place of physical training and its maximum availability to local community have be taken into account of from its design stage. The location of the auditorium itself has to be close to the main entrance of the school for easy access, its facilities located in one common area, their management and maintenance scheme adopted appropriately but legally, and then security and safety measurement have to be devised. Also, more studies are necessary to propose detail regulations for local sports facilities and to develop their interrelationship and network, in connection with sophistication of school facilities and BTL system.

Moonpools are vertical wells in a floating body used onboard many types of vessels like Exploration and drilling vessels, Production barges, Cable-laying vessels, Rock dumping vessels, Research and offshore support vessels. Moonpool gives passage to underwater activities for different types of ships as per their mission requirements. It is observed that inside a moonpool considerable relative motions may occur, depending on shape, depth of the moonpool and on the frequency range of the waves to which the ship is exposed. The vessel responses are entirely different in zero and non-zero Froude number. Former situation is paid attention in this study as the mission requirement of the platform is to be in the particular location for long period of operation. It is well known that there are two modes of responses depending on the shape of the moonpool viz., piston mode for square shape and sloshing mode for rectangular shapes with different aspect ratios of opening like 1:1.5 and 1:2 ratios. Circular shaped moonpool is also tested for measuring the responses. The vessel moored using heavy lines are modelled and tested in the wave basin. The pretensions of the lines are varied by altering the touchdown points and the dynamic tensions on the lines are measured. The different modes of oscillations of water column are measured using wave gauge and the vessel response at a particular situation is determined. RAOs calculated for various situations provide better insight to the designer.
