Recently, the definition of work space contains so many meanings. Basically, this means space where handling various information and developing numerous creative activities. Moreover, the work space is important not only for individual itself but also organizational development. This research is studied for suggesting revitalization of advanced work efficiency, deriving motivation as well as creative operation support for harmonious communication. In order to make the better creative work places, "concentration and motivating interests between members of organization", "Necessity of environment for development and operational progress of work", "improvement and creativity of work and importance of the physical environment" and "harmonious communication and development of advanced community" should be considered. This research arranged based on ALCEMIS model and used actual examples on each step for better understanding of creative work spaces. ALCEMIS model is as follows: (1) Opportunity Finding (2) Fact Finding (3) Opportunity Definition (4) Idea Finding (5) Evaluate & Select (6) Plan (7) Acceptance (8)Execution' over the eight-step details to proceed through the 1. Discovert ((1)+(2)) 2. Dream ((3)+(4)) 3. Design((5)+(6)) 4. Destiny((7)+(8))y" It has been understood that many works related to creative jobs make good use of public spaces to progress operational improvement. The place where co-workers share with can create more effective and fulfilling outcome and satisfaction than independent and exclusive places. Especially creative jobs need this kind of spaces for better communication and cooperation.

The purpose of this study was to examine contents and activities of patterns and functions in the 7th national curriculum for elementary school mathematics and textbooks developed based on it. Through examination, several conclusions were drawn as follow. First, pattern need to be introduced as a way of doing mathematics not as a subject of mathematics. Finding patterns is one of the most important mean to do mathematics. Second, activities for patterns and functions must be organized coherently. Coherent means that mathematical ideas are linked to and build on one another so that students' understanding and knowledge deepens and their ability to apply mathematics expands. Third, independent lessons for patterns and functions are needed. In these lessons, various activities need finding patterns can be introduced to help students understand mathematics. Fourth, the linkage between patterns and functions should be strengthened.

In this paper we apply several variations of independent component analysis( ICA) methods, such as spatial ICA (sICA), temporal ICA (tICA), and spatiotemporal ICA (stICA), to yeast cell cycle datasets, and compare their performance in finding components that result in gene clusters coherent with annotations and in extract ins meaningful temporal modes. It turns out that the results of tICA are superior to those of PCA, sICA, and stICA in terms of gene clustering and the temporal modes extracted by stICA highlights particular cellular processes.

The criteria for construction of D-optimal design in nonlinear models are derived. The procedures for finding these optimal designs using the simulated annealing algorithm are presented. It is claimed that the advantages of this method are its ability to make the given data useful by adding new observations as well as to obtain a new set of appropriate data when the model and parameters are known. Research so far indicates that there has never been a case in which there is more than one independent variable but this method can be used for such cases. The result indicates the effectiveness of the method using simulated annealing algorithm for situations in which there are many independent variables and the ranges of design spaces are wide.

In this paper, we derive an algorithm and develope a computer program which analyze rapidly and precisely the inverse kinematics of robotic mechanism with spatial complex chain structure based on the relative coordinates. We represent the inverse kinematic problem as an optimization problem with the kinematic constraint equations. The inverse kinematic analysis algorithm, therefore, consists of two algorithms, the main, an optimization algorithm finding the motion of independent joints from that of an end-effector and the sub, a forward kinematic analysis algorithm computing the motion of dependent joints. We accomplish simulations for the investigation upon the accuracy and efficiency of the algorithm.

As a functionally complicated facility, it requires rational strategy to accommodate multi-functional needs to plan a hospital. Ambulatory surgery units located in large hospitals have problems such as longer waiting time and congestion for patients due to complicated planning and organization within limited area, which raise needs for independent ambulatory surgery centers to enable smoother medical treatment for patients. To design an independent ambulatory surgery center, understanding of zoning and layout of each unit needs is particularly required. This study focuses on research of efficient zoning/organization of day surgery unit and circulation arrangements of ambulatory surgery centers by analyzing various examples abroad, which will eventually help finding appropriate way of planning domestic ambulatory surgery centers. Specific area of research includes ambulatory surgery process, programmatic requirements, spatial organization of the facility, layout of surgery unit and circulation arrangements of ambulatory surgery centers.

This paper will focus on improving the performance of orthogonal frequency division multiplexing (OFDM) in Rayleigh fading environments. The proposed technique will use a previously published method that has been shown to improve OFDM performance in independent fading, based on ordered sub-carrier selection. Then, a simple non-iterative method for finding the optimal bit-loading allocation was proposed. It was also based on ordered sub-carrier selection. We compared both of these algorithms to an optimal bit-loading solution to determine their effectiveness in a correlated fading environment. The correlated fading was simulated using the JTC channel models. Our intent was not to create an optimal solution, but to create a low complexity solution that can be used in a wireless environment in which the channel conditions change rapidly and that require a simple algorithm for fast bit loading.

As a number of archaea are ubiquitously found in non-extreme habitats, elucidation of their functional roles becomes currently an emerging issue. However, most of them are unable to grow in pure culture and so it remains to be established. In order to find genes lacking in the genome of an ammonia-oxidizing archaeon (AOA), we here report on the comparative analyses of an AOA genome with those of experimentally or theoretically established minimal genomes for independent growth. We assessed the genes lacking in AOA using logic of clusters of orthologous groups (COG), remote homology, consensus sequence weight matrix, function-based motif or domain, and then further excluded genes encoding hypothetical orarchaea-specific proteins. The results of these combination analyses revealed 19 candidate genes lacking in the genome of an AOA. Thus, our results provide a possibility of inducing independent growth of AOA when supplemented with product (s) of the lacking gene (s), and also give a chance for finding new proteins with novel sequence or structure space even if the predicted lacking-genes will be found using another algorithms or biochemical studies.

This study examines the relationship between the effectiveness of an audit committee and the amount of audit fees. The sample consists of 130 manufacturing companies listed on the Indonesia Stock Exchange (IDX) in 2016-2017. Data are obtained from the IDX and company's annual reports. The effectiveness of an audit committee is measured by independent audit committee size, frequency of audit committee meetings, and expertise of the audit committee. Results show first that the size of the independent audit committee has a positive effect on audit fees. This finding suggests that an increase in the number of independent audit committee members produces a higher quality of reporting, and so they tend to choose a reputable public accountant. Second, the frequency of its meetings has positive effects on audit fees. It suggests that the more effective the supervision of the committee to improve audit quality, the higher the audit fees to be paid. However, this study fails to provide evidence that the expertise of the audit committee affects audit fees. The result of this study suggests that the audit committee tends to adopt the demand approach based on the reputation of the public accounting firm accountant firm in determining the amount of audit fees.
