Modular construction technique is an adaptation of factory-based mass production concept in ordinary manufacturing industries to construction industry and it assumes that panels, units, etc. are fabricated in factories and assembled in construction sites. Given its structural limitations, modular construction technique is primarily used in low-story buildings whose maximum height is usually five stories, but researchers are actively studying possible adaptation of modular construction technique to high-rise building designs these days as in the case of infill-type modular construction design. Infill-type modular construction technique, most frequently used in high-rise building construction projects, completes frame construction first in reinforced concrete structures and fills unit modules in such structures. However, infill-type modular construction technique leads to longer construction schedule accompanying increase in construction cost, cost overrun due to additional of temporary work, and possible damage to units in the wake of facility construction. Accordingly, this study is performed as a basic study for the development of bottom-up infill-type modular construction technique intended to construct structural frames and fill in units sequentially in a bid to address such drawbacks of current infill-type modular construction technique.

Purpose: The anterior region is a challenge for most clinicians to achieve optimal esthetics with dental implants. The provisional crown is a key factor in the success of obtaining pink esthetics around restorations with single implants, by soft tissue and inter-proximal papilla shaping. Provisional abutments bring additional costs and make the treatment more expensive. Since one of the aims of the clinician is to reduce costs and find more economic ways to raise patient satisfaction, this paper describes a practical method for chair-side fabrication of non-occlusal loaded provisional crowns used by the authors for several years successfully. Methods: Twenty two patients (9 males, 13 females; mean age, 36,72 years) with one missing anterior tooth were treated by using the presented method. Metal definitive abutments instead of provisional abutments were used and provisional crowns were fabricated on the definitive abutments for all of the patients. The marginal fit was finished on a laboratory analogue and temporarily cemented to the abutments. The marginal adaptation of the crowns was evaluated radiographically. Results: The patients were all satisfied with the final appearance and no complications occurred until the implants were loaded with permanent restorations. Conclusions: The use of the definitive abutments for provisional crowns instead of provisional abutments reduces the costs and the same results can be obtained.

This paper presents a development result for image processed tracking system of multiple moving objects based on Kalman filter and a simple window tracking method. The proposed algorithm of foreground detection and background adaptation (FDBA) is composed of three modules: a block checking module(BCM), an object movement prediction module(OMPM), and an adaptive background estimation module (ABEM). The BCM is processed for checking the existence of objects. To speed up the image processing time and to precisely track multiple objects under the object's mergence, a concept of a simple window tracking method is adopted in the OMPM. The ABEM separates the foreground from the background in the reset simple tracking window in the OMPM. It is shown through experimental results that the proposed FDBA algorithm is robustly adaptable to the background variation in a short processing time. Furthermore, it is shown that the proposed method can solve the problems of mergence, cross and split that are brought up in the case of tracking multiple moving objects.

This paper describes an speaker-adaptive speech recognition system which make a reliable recognition of speech signal for new speakers. In the Proposed method, an speech spectrum of new speaker is adapted to the reference speech spectrum by using Parameters of a 1st linear transformation network at the front of phoneme classification neural network. And the recognition system is based on semicontinuous HMM(hidden markov model) which use the multilayer perceptron as a fuzzy vector quantizer. The experiments on the isolated word recognition are performed to show the recognition rate of the recognition system. In the case of speaker adaptation recognition, the recognition rate show significant improvement for the unadapted recognition system.

The purpose of this study is to comprehend western style in fashion and to contemplate the hybrid tendency reflected on western style, thereby to analyze the aesthetic characteristics of the hybrid tendency of western style. For such purposes, this study first examines western style historically, in order to analyze hybrid tendency reflected on western style, and conduct a case study by analyzing photographic materials of pr t- -porter collection since 1980s. The result of this study is as follows: the hybrid tendency reflected on western style are modification and fusion of regional culture, adaptation and composition of subcultures, and appropriation of sexual minority culture. (1) Modification and fusion of regional culture is expressed in ethnic items and patterns of embroidery, mixing Mexican and Spanish, American Indian and American cultural references. (2) Adaptation and composition of subcultures emphasize traditional or vintage western style by mixing characteristics of western and other subcultures. (3) Appropriation of sexual minority culture is expressed in rhinestone chaps and fetish corset, glitter rodeo suit, reminiscent of drag or queer cultural references. The result of this study will provide basis which can be utilized in the development and educational background of fashion design.

The purpose of this study was to compare the results of climate change prospect and vulnerability assessment and the awareness of those by public officials and citizens at Yeongwol county, Gangwon province where experiencing the most climate change vulnerability. Data of 12 meteorological categories such as mean temperature at Yeongwol weather station from 1995 to 2013 were analyzed. Climate change vulnerability was assessed with 29 sub-categories in 6 categories (health, emergency/disaster, agriculture, forestry, water management, ecosystem) of National Institute of Environment Research's LCCGIS (2013). The awareness of climate change and its vulnerability was surveyed with 154 citizens and 130 officials at Yeoungwol county. The climate change prospect and its vulnerability was similar to the actual climate change effect. However, the awareness of climate change was different between some officials and citizens. The results of this study would be base data for the Yeoungwol county's future climate change adaptation poicy making.

As abnormal weather events due to climate change continue to rise, landslide damage is also increasing. Given the substantial time and financial resources required for post-landslide recovery, it becomes imperative to formulate a proactive response plan. In this regard, landslide susceptibility analysis has emerged as a valuable tool for establishing preemptive measures against landslides. Accordingly, this study conducted an annual landslide susceptibility analysis using the history of landslides that occurred over many years in the Jeolla region, and analyzed areas with a high potential for landslides in the Jeolla region. The analysis employed an ensemble model that amalgamated 10 data-based models, aiming to mitigate uncertainties associated with a single-model approach. Furthermore, based on the cumulative data regarding landslide susceptible areas, this research identified regions vulnerable to recurring landslide damage in Jeolla region and proposed specific strategies for utilizing this information at various levels, including local government initiatives, adaptation plan development, and development approval processes. In particular, this study outlined approaches for local government utilization, the determination of adaptation plan types, and considerations for development permits. It is anticipated that this research will serve as a valuable opportunity to underscore the significance of information concerning regions vulnerable to recurring landslide damage.

The era of globalization has ushered in dramatic changes in the past decade covering a wide range of distinct political, economic and cultural trends whereby people adapt their houses to suit their needs and desires. This paper discusses the process of change analytically, emphasizing the importance of understanding the transformation of Lao traditional houses and its impact factors to the transformation and adaptation to suit with globalization trend, and conservation of the characteristics of traditional houses. This study takes place in Luangprabang, an ancient city of Lao PDR, which was designated as a world heritage city in 1995 as it is rich with diverse, tangible and intangible values. Five cases of traditional house in Luangprabang are examined to understand their transformation through time, by analyzing the basic spatial formation, components and elements, especially to find out the impact factors to such transformation. The study revealed that the transformation of the traditional house is subject to not just one single factor, but to a number of factors, where globalization, regulation, economy, and social aspect factors play a prime role and are the root for all these changes. The case study also indicates that these changes are connected to the benefits of income generation as a survival strategy for the low and middle-income people in Luangprabang as well as the housing demands. In the transition period a new residential type appeared accordingly, in which living spaces were categorized according to their general functions. There was a harmony between people's needs and the physical characteristics of the house.

Shoe's size and shape are determined by the last that takes shape of foot because last is the mold of shoe in development and manufacturing process. Then adaptation between foot and shoe is dependent on the last. In mass shoe production, model size is developed in the first place, other sized lasts are made through the grading process based on model size. The most important factor in grading system is grading deviation that must be same amount induced from foot measuring database. At present, most of the last manufacturing companies in korea using 260mm as a standard foot model size. When length grading deviation is 5mm, the ball girth grading deviation is 3.7mm and the ball width grading deviation is 1.2mm. I verified existing grading system by comparing grading results with foot measuring data. Also, I proposed reasonable grading deviation and application method of grading system. From the analysis of foot measuring database, reasonable grading deviations are 1.22mm in ball width and 0.84mm in ankle height in case of length grading deviation is 5mm. I confirmed that the current grading system is very accurate. When we grade last from 230mm to 290mm by current grading system based on model size 260mm, there is grading error over 1mm in the front outside area of foot. This error level of 1mm is no problem in normal walking shoe's last, but it induces adaptation problems in sports and special purposed shoe's last. Therefore using of three standard model size is recommended in grading men's last for reducing grading deviation error under the level of 1mm. It is specifically described as 235mm in 225-245mm, 260mm in 250-270mm, 285mm in 275-295mm. According to the above recommended grading system, it is enough to measure only three foot sizes in case of foot measuring project for men's last development.

The purpose of this study is to present a method of preparing for a more enduring built environment, being fully aware that, in consideration of time flowing from past to present, there is no ardlitecture in creation that is not abandoned. Efforts were made to find the problem solutions in relation to the hierardlial structure, evolvement and adaptation of living beings. The process of study was as follows, ·The built environment's affordance to human beings and the designer's role was explained. ·Having an understanding of the necessity of user minded planning, the architectural adaptation of the multi-layered hierarchy system of holon theory and adoption of time conception into architectural space were examined to explain that the importance in ardlitecture should be placed in transition, not in perfection. ·The design of Parc de La Villette by Bernard Tsdlumi was analysed from the above viewpoint. Having a practical case analysed, this study is expected to offer a basic information for use in case of visual presentation of a theoretical viewpoint.
