Nowadays, food style would be changing as western and much like simple. because there was changing for customer both life style and recognition of what the food is, so that the customer would like to get something that has a high qualified and special. In the society changing continuary, the upgraded speed of atmospher and competition between bakery company is running quickly. in order to follow the customer who are different individually and pursuit lots of kind of things. In fact, it's not only making atmosphere that could give relaxation and rich life but also supporting commodity and many kinds of information to effect the sale's effectiveness, so the various alternative need to be checked out to treat the difference of atmosphere. importance of space composition plan considerating specific character is confirmed each commercial area of alternatives. In this study, we want to provide the most important standard of space composition of several visible or invisible environment factor making an bakery store. commercial rights are defferentiated between center commercial land and dwelling commercial land and we can strengthen the competitveness by bringing inspect, analysis, comparison about product make-up price each commercial land in space organixation of in-store actively in the 21 century's new bakery competition. In the 21st century, we should recognize we are in the new period about these a aggressive goal of maximization of sales and performed space construction through plan specialization to build reasonably and effectively. composition plan for store space as composition rate of product would be basic plan. so when the opening store is decided it need to be basic composition plan space which Is proper to situation of area.

Background and Objectives: Supraglottic cancer have a great tendency to spread cervical lymph nodes and lymph node metastasis is a well known prognostic factor. However the treatment for N0 neck in supraglottic cancer is still controversial. Materials and Methods: We retrospectively analyzed our neck management of supraglottic cancer patients who present with cN0 contralateral neck from 1989 through 1997. 36 patients were eligible for analysis. The primary site was surgically removed and the neck was managed by elective neck irradiation (ENI), elective neck dissection (END), or therapeutic neck dissection (TND) with postoperative radiation therapy (PORT). Results: Our results revealed that 18 of 36 patients have clinically negative neck, another 18 patients have clinically positive neck (N1-3). In clinically negative group, 12 of 18 patients were received ENI and there was 1 failure in contralateral neck area. Remaining 6 patients were received END with PORT and there was no failure. In clinically positive neck group, 3 of 18 patients were received ipsilateral TND and an additional contralateral END with PORT. Remaining 15 patients who were received TND with PORT, developed 3 neck failure. Conclusion: ENI or ipsilateral or bilateral END can be done in the cN0 neck of supraglottic cancer however ipsilateral TND and contralateral END with PORT is reasonable for the cN(+) neck.

The suspended dome system is a new structural form that has become popular in the construction of long-span roof structures. Suspended dome is a kind of new pre-stressed space grid structure that has complex mechanical characteristics. In this paper, an optimum topology design algorithm is performed using the enhanced colliding bodies optimization (ECBO) method. The length of the strut, the cable initial strain, the cross-sectional area of the cables and the cross-sectional size of steel elements are adopted as design variables and the minimum volume of each dome is taken as the objective function. The topology optimization on lamella dome is performed by considering the type of the joint connections to determine the optimum number of rings, the optimum number of joints in each ring, the optimum height of crown and tubular sections of these domes. A simple procedure is provided to determine the configuration of the dome. This procedure includes calculating the joint coordinates and steel elements and cables constructions. The design constraints are implemented according to the provision of LRFD-AISC (Load and Resistance Factor Design-American Institute of Steel Constitution). This paper explores the efficiency of lamella dome with pin-joint and rigid-joint connections and compares them to investigate the performance of these domes under wind (according to the ASCE 7-05), dead and snow loading conditions. Then, a suspended dome with pin-joint single-layer reticulated shell and a suspended dome with rigid-joint single-layer reticulated shell are discussed. Optimization is performed via ECBO algorithm to demonstrate the effectiveness and robustness of the ECBO in creating optimal design for suspended domes.

Many studies have shown that having perception of spatial information is important for air traffic control officer (ATCO) since it helps them understand the current situation and predict the situation it leads to. However, little or no research has been done to investigate if there is any difference at the levels of expertise in perceiving spatial information and predicting a prospective situation. This study investigates the difference between expert and novice ATCO groups in how accurately each group of ATCO perceive spatial information such as position, altitude, speed, and flying direction, and predicting such information they will encounter shortly. In completing a task to watch the movement of airplanes displayed on the computer monitor as a blip, the participants were asked to predict the position, speed, and the altitude of the aircraft in a minute by marking on the sector map. The results show that the expert group performed better in accuracy and had tendency to overestimate on position and altitude; however, no significant difference was found between the two groups in terms of reading a flying direction. Therefore reading a flying direction may not be a reliable indicator to judge expertise of ATCO. But the expert group shows better predicting performance by perceiving spatial information such as airplane's position and altitude with feeling on time. The study suggests that it is important to enhance perceptive skills in ATCO training in improving their expertise in predicting accuracy traffic situation, preventing from air collision, and improving productivity for more efficient air traffic flow. A further study on the relationship between the perception of spatial information and the sense of time in predicting future information and effectiveness as an independent factor would contribute to providing more insights into expertise of ATCOs.

Recent seismic events occurred in Italy (Emilia-Romagna 2012, Abruzzo 2009) and worldwide (New Zealand 2010 and 2011) highlighted some of the weaknesses of precast concrete industrial buildings, especially those related to the connecting systems traditionally employed to fasten the cladding panels to the internal framing. In fact, one of the most commons fails it is possible to observe in such structural typologies is related to the out-of-plane collapse of the external walls due to the unsatisfactory behaviour of the connectors used to join the panels to the perimeter beams. In this work, the strengthening of a traditional industrial building, assumed as a case study, made by precast reinforced concrete is proposed by the adoption of a dual system allowing the reinforcement of the structure by acting both internally; by pendular columns and, externally, on the walls. In particular, traditional connections at the top of the walls are substituted by devices able to work as a slider with vertical axis while, the bottom of the walls is equipped with two or more hysteretic dampers working on the uplift of the cladding panels occurring under seismic actions. By means of this approach, the structure is stiffened; obtaining a reduction of the lateral drifts under serviceability limit states. In addition, its seismic behaviour is improved due to the additional source of energy dissipation represented by the dampers located at the base of the walls. The effectiveness of the suggested retrofitting approach has been checked by comparing the performance of the retrofitted structure with those of the structure unreinforced by means of both pushover and Incremental Dynamic Analyses (IDA) in terms of behaviour factor, assumed as a measure of the ductility capacity of the structure.
