This study was carried out to suggest the effective reinforcing method which can evaluate the tensile capacity of cast-in-place anchor with cracks. Currently, cast-in-place anchor is used widely for the fastening of equipment in Korean NPPs. 26 test specimens with a single anchor under 4 cracked conditions are prepared using plain concrete. The distance between crack and anchor and reinforcing materials were selected as the main test variable. The tensile force was applied using a actuator with a capacity of 100 tonf using a displacement control method of 0.5 mm/min velocity. Test results from this result show the combination of carbon plate and epoxy will be more available for repair and reinforcement of equipment foundation system in NPPs. Further experimental work is indeed involving the epoxy injection effect and adjustment of reinforcing location of carbon sheet.

Lived space, i.e. space as we experience it in our mundane life, does not exist independently of material objects: it is defined, delimited and made sensible by them. Concrete spaces so manifest are not sterile and neutral homogeneous voids. Not only do they interact with material objects but also influence our feelings and behaviour, constituting emotionally charged fields. This field dynamics of space is readily observed in the phenomenon of place as well as in the etymology and usage of the word 'place'. Each space is pervaded by a particular mood or atmosphere in accordance with its size and shape as well as with the perceptual properties of its constituent objects. Moreover, within each space the atmosphere also changes depending on the location. Space then can be thought of as a nonhomogeneous field of emotional energy. The fact that one is attracted to some places and repulsed by others may be described as one's being subject to invisible forces of pulls and pushes, attractions and repulsions. Out spatial environment is therefore a field of forces of varying directions and magnitudes.

Recently, many social networking services using mobile devices are spread. Also, many studies based on location and time are increasing. However, existing studies have been difficult to resolve queries by place, time, and events. In the paper, we propose time and space modeling method for social services. We propose Human Activity Graph and Quad Relation Factors through time, place, event, and social activity of users, and we design the database scheme for data collect and analysis.

In this paper, I investigate the acoustic correlates of a vowel's coarticulatory dynamics manifested in preceding and following consonants along two dimensions of the vocal tract: place of articulation and degree of constriction. Two dimensional coarticulation is not necessarily executed either concomitantly or proportionally, and the modification induced by coarticulation with a vowel in CVC structures is merely restricted to the CV portion; that is, the prevocalic consonant is modified solely in its constriction location. This is consistent with the observation that C-to-V place assimilation does not accompany consonant lenition in phonology, which suggests that phonetic nature is effectively reflected in phonological patterns.

This paper presents a locally deterministic abstract machine for a new process model LocPi which is based on a subset of asynchronous polyadic π-calculus and enriched with locations and process mobility. Our calculus has a primitive for migrating and spawning a process to a location(remote site), but does not explicitly represent the place which a process are running at. Running processes may have names attached with their locations and the communication reductions can occur only on located names. So we present how to assign locations to unlocated names. Without a global channel environment, these located names enable us to locate the place which input actions occur at and output messages should be sent to.

This study makes a general view of human-, natural environment, actual condition of use, management and administration of Sissinghurst castle garden and proposes the following directions for our model of herb industry, herb garden plan with the analysed results. 1) The location of herb garden should be selected at a place where Is close to scenic spots, sight-seeing place or big city and conveniently situated, 2) For the basic design of herb garden, the ecological features, human -, natural environment should be analysed and for the implementation of the plan, it should have variety and coordination to give the pleasure and appreciation to the users. 3) For the plan of herb garden, time limit system and number limit admission have to be introduced by calculating carrying capacity so that the user can have a comfortable atmosphere and the garden should be environment - friendly.

The heat transfer processes taking place in the side wall of a thermocline enclosure have been analyzed for idealized conditions based on the assumption that, at any instant time, side wall heat transfer processses are independent of the thermocline bulk motion. However, the axial tempera-ture distribution in the thermocline core provides the means for specifying the liquid medium-side boundary condition to the enclosure side wall. A picture is drawn which reflects the side wan response to thermocline bulk motion within the frame work of a quasi-steady analytic approach. For valves of the parameters typical of systems of engineering interest, the analysis shows that a significant amount of heat transfer short - circuiting can take place along the side wall enclosure. This phenomenon is favored by high values of $H_l$ and low values of P and $H_g$ respec-tively. The location of the point of zero normal heat flux on the side wan can be expected to mark, approximately, the region of confluence of two sidewall boundary flows respectively driven by the buoyant effects.

This study look into a role change and geographical inertia of the central place. The place is selected and progressed as the center which is the joining of physical condition and social situation of the region. The central place is the role change according to social change but it has geographical inertia as the central place. The result is as follows. Firstly, the role of regional center is changed. This sample region is the center of a national defense and administration and traffic in Three-Country period. But the role of the national defense is disappeared with the unity of the three countries. A traffic center facility was lost because of traffic axis changed from the east-west line to the north-south line when Ko-Ryo period. A facility loss as a traffic center leads to diminish the administration function and the movement of the regional center within that area. Secondary. the new regional center function was maintained by the joining of an outside and inside peoples. It maintained the geographical inertia by Confucianism culture instead of administration function. Thirdly, it had geographical location movement within the area.

This study is to determine an optimal yacht mooring location candidate among many alternative candidates in order to obtain the maximized efficiency under the natural conditions using integer programming. To deal with marina's construction location, the optimal construction location is selected using 21 important factors analysis for 4 candidates in the Mokpo city. The development period and the initial investment cost weight are one and half times more than the others among 21 factors. The optimal spiral analysis of weighted linear model shows that the Peace Square sea area is selected as the most optimal place among 4 candidates. This proposed model has not been applied in the optimal marina's facility candidate selection problem yet. This paper will contribute to determine the most reasonable alternative. Also, this proposal model can be applied to other marina's facility candidate selection problem in other regions.

In this paper, we propose a Time Delay Traceback Scheme for the TDOA location estimation performance enhancement in NLOS environment and analyze the performance in various conditions. We place multiple readers in a square($300m{\times}300m$) searching area for reuse of received signal. Also, we use more active NLOS reader detection methode for NLOS error mitigation. when NLOS time delay 70 m, the number of the NLOS reader is 3 and the received sub-blinks number 3, proposed time delay trace-back scheme improve the RMSE about 16 m. From these results, we confirm that the proposed time delay traceback scheme is well-suited for the high precision location estimation to offer the location based service.
