Purpose: The purpose of this study is to identify the determinants of store occupancy based on the rental characteristics of small and medium-sized enterprises (SMEs) renting buildings across the country, and to analyze the satisfaction level after opening. Research design, data and methodology: The study conducted an empirical survey through questionnaires targeting individual business owners, corporate representatives, and executives and employees nationwide, including Seoul, Gyeonggi, and other metropolitan areas and provincial cities. Results: In this study, the most important factor that SMEs consider when deciding whether to rent a commercial building or office is financial characteristics, followed by management characteristics, location characteristics, building characteristics, and facility characteristics. In addition, management characteristics were found to have the greatest impact on rental satisfaction of SMEs, followed by financial characteristics, building characteristics, and location characteristics in order. Conclusions: Since the lessor cannot immediately improve the location characteristics or building characteristics, in order to increase the rental satisfaction of small and medium-sized businesses in a relatively short period of time, it is necessary to improve managerial characteristics such as prompt civil complaint handling and clean management of the building. In addition, it is analyzed that if the factors that can reduce the burden on the tenants are found in advance and reflected in the financial characteristics, the satisfaction of the tenants can be increased.

It is known that an EEG is characterized by the unique and personal characteristics of an individual. Little research has been done to take into account these personal characteristics when analyzing EEG signals. Often the EEG has frequency components which can describe most of the significant characteristics. These combinations are often unique like individual human beings and yet they have an underlying basic characteristics as well. We think that these combinations are the personal characteristics frequency components of the EEG. In this seminar, the EEG analysis method by using the Genetic Algorithms (GA), Factor Analysis (FA), and the Neural Networks (NN) is proposed. The GA is used for selecting the personal characteristic frequency components. The FA is used for extracting the characteristics data of the EEG. The NN is used for estimating the characteristics data of the EEG. Finally, in order to show the effectiveness of the proposed method, classifying the EEG pattern is carried out via computer simulations. The EEG pattern is evaluated under 4 conditions: listening to Rock music, Schmaltzy Japanese ballad music, Healing music, and Classical music. The results, when personal characteristics frequency components are NOT used, gave over 80 % accuracy versus a 95 % accuracy when personal characteristics frequency components are used. This result of our experiment shows the effectiveness of the proposed method.

The transient characteristics of separately excited d-c motor driven by thyristor d-c chopper is studied in this paper. The armature controlled system is applied. As a result of theoretrical analysis the following conculsions were drawn: (1) For the transient analysis, it is recognized that the state transition analysis is a more general method and powerful tool than the state equation method or signal flow graph method, although it includes iterative matrix calculations. And the system is dealt with a finite width sampled-data system in the state transition analysis. (2) The transient characteristics of the motor angular velocity and its torque to the sampling duration variation are compared with those due to the amplitude variation of d-c chopper voltage as follows. The attenuation rate of the transient characteristics is equal in both cases, but the initial value of the transient characteristics in former case is greater than in latter case. (3) The roots of characteristics equation of the system lie inside the unit circle of the Z-plane. Therefor the system is stable. Further it is found that as the sampling duration is decreased the relative stability is lessened.

In this study, the general characteristics, and theories of cochlear concerning with hearing are examined. Also the digital method is studied in order to analyze with microcomputer on the model equation of basiliar membrane in the cochlear derived from 3-dimensional rectangular block model which is studied by Boer. The method is illustrated for the amplitude characteristics of basiliar momtrane wave velocity. The results obtained are as follows; 1. In the magnitude characteristics, the velocity gradually increases from the stapes, shows the maximum magnitude, and then rapidly decreases to the Helicotrema. 2. The characteristics of 3-dimensional model is located between 1-and 2- dimensional models in the velocity characteristics coefficients, magnitude characteristics, and the pattern of 2-dimensional model shoves the different features from the 1-dimensional and 3-dimensional rectangular block model. 3. In the 3-dimensional rectangular block model, the characteristics of the waveform and the maximum resonant point are same whether Z(X) is linear or nonlinear.

The primary purpose of this study is to examine the interaction effects of organizational characteristics as contextual variables on the relationship between relational exchange characteristics and ASP service performance. The effect of relational exchange characteristics on ASP service performance has been also investigated. For this purposes, we developed a research model based on the literature reviews of ASP services, relational exchange theory, and contingency theory. A total of 106 usable survey responses from companies using ASP services has been analyzed in the study. The findings indicate that (1) flexibility and partnership had a positive influence upon noneconomic profit, (2) information sharing had a positive influence upon economic profit, (3) organizational size and IS maturity had a partial moderating effect on the relationship between relational exchange characteristics and ASP service performance, and (4) the subgroup analysis, conducted to determine the exact nature of interaction effect, reveals that the relationship between relational exchange characteristics and noneconomic profit is significantly stronger with a high level of organizational size than with a low level, and that the relationship between relational exchange characteristics and economic profit is significantly stronger with a low level of IS maturity than with a high level.

MIS researches involve, in particular, the problems of developing appropriate IS for given MIS environments and lay emphasis on identifying prominant IS characteristics pertaining to the system in issue. This study deals with the IS characteristics for the management task of "planning". It investigates empirically the impacts of IS characteristics, under a set of proposed hypotheses, with particular respect to users' information satisfaction and performance in carrying out the task of planning. Futhermore, it examines whether the IS characteristics have different effects depending on the planning modes on the part of IS users. Based on a group of hypotheses accepted, the IS characteristics for planning decision making are not only proposed according to planning modes: preactive, reactive and proactive, but also classified into six subsystem categories: input, process, ouput, storage, interface and communication. Finally, the implications of the findings are discussed.
