Although the frequency of use for community facilities in rural villages is growing as well as the importance of the facilities for urban-rural exchange is being highlighted, study on spatial location-analysis of the facilities for such multi-purpose is not so much. This study aims to find the spatial distribution forms of community facilities in rural villages such as community center and rural-pocket park through location-analysis, in order to provide available data for selecting location in the future. As the study area, Sojeong-myeon, Sejong Special City was selected. This study conducted GIS analysis for criteria of the location-evaluation model developed in this study. This study introduced the concept of time-distance for accessibility analysis. This paper also used linear-consecutive scoring method(LCSM) as a scoring method of criteria and Analytic Hierarchy Process(AHP) method for weighting values of criteria. The application results showed that the new model can generate the intensity of community facilities according to spatial distribution and accessibility from cities to the facilities.

This study is intended to set the concept of becoming meaning of digital space through digital technology and to study the influence of digital space on becoming of real space through derived keyword. The results of this study are summarized as follows. First, the digital concept is created in the process that the virtual space is changed into the real space with a priority given to form, space and time. Digital expression concept and image concept the structural becoming, and idea concept and creative concept creates the time becoming. Second, the concept of digital becoming exposes a physical visibility through the digital's virtual image, and non-space spatiality through the space simulation. It also continuously reveals a consecutive time and non-consecutive time through a statable progress, incremental progress, and dynamic progress. Third, as the influence of digital on becoming of real space, the digital visibly not only expresses the new and difficult becoming problem through conceptual virtuality, but also can review the real space's space concept with virtuality in the digital non-area. Digital's durability expresses the new space's existence by physically combining with the existing space through the virtual form creation.

In this paper, we present the detection method of moving objects based on two background models. These background models support to understand multi layered environment belonged in images taken by shaking camera and each model is MBM(Multiple Background Model) and TMBM (Temporal Median Background Model). Because two background models are Pixel-based model, it must have noise by camera movement. Therefore correlation coefficient calculates the similarity between consecutive images and measures camera motion vector which indicates camera movement. For the calculation of correlation coefficient, we choose the selected region and searching area in the current and previous image respectively then we have a displacement vector by the correlation process. Every selected region must have its own displacement vector therefore the global maximum of a histogram of displacement vectors is the camera motion vector between consecutive images. The MBM classifies the intensity distribution of each pixel continuously related by camera motion vector to the multi clusters. However, MBM has weak sensitivity for temporal intensity variation thus we use TMBM to support the weakness of system. In the video-based experiment, we verify the presented algorithm needs around 49(ms) to generate two background models and detect moving objects.

A teaching manual was developed to incorporate the creative problem solving process into a fashion marking course. Students' creativity, problem solving, critical thinking, and analytical thinking are promoted by applying the creative problem solving process systematically to solve authentic business problems experienced by local apparel business owners. This teaching manual is based on the FourSight Model that consists of Clarify, Ideate, Develop, and Implement. Various tools promoting divergent thinking are also utilized in the process. A local fashion business is invited as a problem owner and four resource groups are formed with students based on the results of the Kirton Adaption Innovation Inventory. Each resource group consists of 6-8 students. The creative problem solving process is implemented into a classroom setting as four 75-minutes sessions that are held twice a week for two consecutive weeks. The local fashion business owner will be in presence during the first (Clarify) and last (Implement) sessions. The instructor facilitator meets with the problem owner outside the classroom three times including pre-session client interview, after the second (Ideate) session, and before the third (Develop) session. This modified CPS manual for fashion marketing and merchandising courses provides practical guidelines to work with local fashion businesses while providing students with learning opportunities of the creative problem solving process.

The purpose of this study is to understand the process of "standing alone" in divorced single fathers on the basis of qualitative data collected through in-depth interviews with 10 divorced single fathers. Data were analyzed on the basis of grounded theory analysis in open coding, and 154 concepts, 39 sub-categories, and 14 categories were derived. According to the results of this study, the process phenomenon of divorced single fathers' standing alone was "the restraint and chaos of pain". This study could identify the consecutive process of four identified stages: marriage life's rupture, pain and chaos, deliberation and decision, and role adaption. In selective coding, the core category was "to pass through the restraint of pain and embrace children and stand alone". There were three types of standing alone: maintaining barely, enduring hopefully, and living initiatively. This study showed the necessity of social support and the basic data by type analysis through the process of standing alone. This study provided substantive knowledge generated through the voices of the persons concerned.

A composite material was tested to eliminate phenol in aqueous solution combining adsorption on activated carbon and photocatalysis with $TiO_2$ in two different ways. A first implementation involved a sequential process with a loop reactor. The aim was to reuse this material as adsorbent several times with in situ photocatalytic regeneration. This process alternated a step of adsorption in the dark and a step of photocatalytic oxidation under UV irradiation with or without $H_2O_2$. Without $H_2O_2$, the composite material was poorly regenerated due to the accumulation of phenol and intermediates in the solution and on $TiO_2$ particles. In presence of $H_2O_2$, the regeneration of the composite material was clearly enhanced. After five consecutive adsorption runs, the amount of eliminated phenol was twice the maximum adsorption capacity. The phenol degradation could be described by a pseudo first-order kinetic model where constants were much higher with $H_2O_2$ (about tenfold) due to additional ${\bullet}OH$ radicals. The second implementation was in a continuous process as with a fixed bed reactor where adsorption and photocatalysis occurred simultaneously. The results were promising as a steady state was reached indicating stabilized behavior for both adsorption and photocatalysis.

Objective: Anterior screw fixation provides the best anatomical and functional results for type II odontoid process fracture (type II-A, II-N, and II-P) with intact transverse ligament. The purpose of this study is to evaluate the usefulness of the 4.5mm diameter, cannulated Herbert screw in anterior screw fixation. Methods: From Jan. 2003 to Feb. 2004, consecutive 10cases of type II odontoid process fractures were treated with anterior screw fixation using a Herbert screw. The Herbert screw has double threads, with different pitches on the distal and proximal ends. It has no head, so it can be inserted through articular cartilage and buried below bone surface. It was originally developed for treating scaphoid fractures. Results: There were 8male and 2female patients whose ages ranged from 15 to 67years (mean 42.1years). The fracture type was type II-A in 4patients, II-N in 3 patients, and II-P in 3 patients. The fracture line was oblique downward and backward in 6cases, oblique downward and forward in 1 case, and horizontal in 3cases. The range of follow-up was 5 to 18months (mean 12months). Bone fusions were achieved in all cases without any instrumental failures or postoperative complications. Conclusion: The Herbert screw is very useful in anterior fixation for type II odontoid process fracture. This series showed successful results also in type II-A odontoid fracture when treated with the Herbert screw, but further more studies are required.

High performance green $Ir(ppy)_3$-based phosphorescent OLEDs (PHOLEDs) have been fabricated by organic vapor phase deposition ($OVPD^{TM}$). In addition to demonstrating both efficiency and operational device lifetime comparable to devices built by vacuum thermal evaporation, we report on the controllability and stability of the $OVPD^{TM}$ process. Specifically, run-to-run and day-to-day deposition rate reproducibility of better than 2 % for three consecutive days is demonstrated.

The synthetic control chart (SCC) proposed by Wu and Spedding (2000) is to detect shifts in the process mean. The performance was re-evaluated by Davis and Woodall (2002), and the steady-state average run length (ARL) performance was shown to be inferior to cumulative sum (CUSUM) or exponentially weighted moving average (EWMA) chart This paper proposes a simple adaptive scheme to improve the performance of the synthetic control chart. That is, once a non-conforming (NC) sample occurs, we investigate the next L-consecutive samples with larger sample sizes and shorter sampling intervals. We employ a Markov chain model to derive the ARL and the average time to s19na1 (ATS). We also propose a statistical design procedure for determining decision variables. Comprehensive comparative study shows that the proposed control chart is uniformly superior to the original SCC or double sampling (DS) Χ chart and comparable to the EWMA chart in ATS performance.
