The purpose of this study is to investigate three issues. First, we investigated four control mechanisms that might increase the franchisee's perception of franchiser commitment: a franchiser's TSIs, relational norms, monitoring, and qualification programs. Second, we proposed that appropriateness and efficacy of these control mechanisms in fostering franchiser commitment might be changed over the relationship life cycle. Third, we examined how bureaucracy and levels of franchiser's commitment related to relationship satisfaction. Through empirical analysis, research results indicate that a franchiser's TSIs and relational norms are positively associated with the franchisee's perception of franchiser commitment. In detail, what increase franchisee's perception of franchiser commitment in short-term relationship are franchiser's TSIs but relational norms are more important in the long-term relationship. In addition, the results show that franchisee's perception of franchiser commitment, participation and formalization are positively related to relationship satisfaction.

Purpose: To investigate the status of foot, preventive foot care and appropriateness of shoe size in patients with diabetes. Materials and Methods: One hundred and sixty-five patients who visited endocrinology clinic due to clinically proven diabetes mellitus were studied. Average age was 59.3 years (range, 36-90 years) and average duration of diabetes was $9.6{\pm}8.2$ years. Patients were questioned about their basic educational level and their foot and ankle problems. Physical examination of the foot was done including sensation testing of four areas of plantar surface with the 5.07 monofilament. Both feet and shoes were measured for width, length and the height of toes and toebox. Shoes were defined as properly fitting the foot if it is 5mm wider than the foot, and $20{\pm}30\;mm$ longer than the foot, and the height of toebox is more than 5mm higher than the height of the toes. Results: 48.5 percent of the patients were educated about how to select an appropriate shoewear. 47.3 percent of the patients had symptoms of neuropathy and 42.4 percent of patients were unable to feel the monofilament in at least one area. 25.5 percent of the patients had appropriate shoes in length, 63.6 percent of the patients in width, and 72.7 percent of the patients in the height of toebox. Conclusion: This study suggets that more patients needs to be educated about foot care and appropriate shoes which have adequate height of toebox as well as the length and width.

In this study, a continuous optimum design model with its application program for plane steel frame structures developed. In the model, the sequential unconstrained minimization technique (SUMT) transforming the nonlinear optimization problem with multidesign variables and constraints into an unconstrained minimization problem and the refined plastic hinge analysis method as one of the most effective second-order inelastic analysis methods for steel frame structures were implemented. The total weight of a steel frame structure was taken as the objective function, and the AISC-LRFD code requirements for the local and member buckling, flexural strength, shear strength, axial strength and size of the cross-sectional shapes of members were used for the derivation of constraint equations. To verify the appropriateness of the present model, the optimum designs of serveral plane steel frame structures subject to vertical and horizontal loads were conducted.

In this study, nutrient solution for Liliaceae (Chinese chive) leafy vegetable was developed. The various strength (1/2, 1 and 3/2) of nutrient solution recommended by National Horticultural Research Institute (NSH) was applied to the crops in deep flow technique (DFT) system for 42 days. The growth of Chinese chive were highest in the treatment of 1/2 strength. The proper constitution of nutrient solution developed for liliaceae crops (NSL) was N 12, P 2.5, K 7, Ca 4 and Mg 2 met. The crops were grown two times in March and September to examine the appropriateness of the NSC. As a result, the relative growth rate and the amount of chlorophyll (SPAD value)of Chinese chive treated with NSL were increased 1.11 times. The most important nutrient factor of ascorbic acid were also increased 1.16 times.

Objective : The purpose of this study was to verify the appropriateness of ovariectomized rats as the osteoporosis animal model. Methods : Twelve female Sprague-Dawley rats underwent a sham operation (the sham group) or bilateral ovariectomy [the ovariectomy (OVX) group]. Eight weeks after operations, serum biochemical markers of bone turnover were analyzed; osteocalcin and alkaline phosphatase, which are sensitive biochemical markers of bone formation, and C-terminal telopeptide fragment of type I collagen C-terminus (CTX), which is a sensitive biochemical marker of bone resorption. Bone histomorphometric parameters and microarchitectural properties of 4th lumbar vertebrae were determined by micro-computed tomographic (CT) scan. Results : The OVX group showed on average 75.4% higher osteocalcin and 72.5% higher CTX levels than the sham group, indicating increased bone turnover. Micro-CT analysis showed significantly lower bone mineral density (BMD) (p=0.005) and cortical BMD (p=0.021) in the OVX group. Furthermore, the OVX group was found to have a significantly lower trabecular bone volume fraction (p=0.002). Conclusion : Our results showed that bone turnover was significantly increased and bone mass was significantly decreased 8 weeks after ovariectomy in rats. Thus, we propose that the ovariectomized rat model be considered a reproducible and reliable model of osteoporosis.

Buzz margin scheduling and control technique which are suitable to regulate stable and high pressure air in wide range of Mach number are suggested for fixed geometry of a supersonic intake. From the analysis of preceding study, most effective control variable is induced and scheduling law is newly suggested in a real application point of view. The appropriateness of the control law in wide range of Mach number is addressed by numerical simulation of controlled propulsion system. Also, the simulation for stabilization and tracking performances of the controller are studied to investigate the phenomena under flight maneuver and disturbances.

Recently, the Department has utilized the media facade as a means to attract new customers and promotional tools. In particular, we checked the rate of customer's gender who visited a large department store. The ratio of women's visit is 4.6 times more than men. This can confirm the need to produce a differentiated content of LED media facade by gender. This study are subject to an empirical analysis of differences of perception of evaluation factors of media facade in gender. At first we specified four factors which can evaluate the media facade according to gender by previous studies. There are aesthetics, artistry, comfort and harmony. And the hypothesis was set as "Each factor might be differences between the recognition of their gender" In order to verify a hypothesis the country's large department store was selected and experiment was performed. In the result of the experiment, among the four factors, aesthetics, creativity, and harmony were chosen, while comfort was dismissed. This results confirm that the following factors are needed to attract more women's customer at the department such as combination of space and media facade, combination of shape and color, appropriateness of the information and beautiful place, and directing way of content.

Data redundancy is problematic in that it not only induces heavy storage management cost but also could bring critical degradation of information systems. Unfortunately, to our knowledge, only few enterprises willingly afford time and efforts for the faithful conceptual design to prevent the degree of inappropriate data as much as they could, while most of enterprises pay rare attention to the notion of that sort of data quality. Wondering if there would be any other way to design the enterprise.wide data design without prior knowledge about business works is our major motivation for this study. In this paper, we present our data modeling methodology in which associations among objects in each sentences of a business job descriptions are treated as the focal point in database design. A proposed agent for automated design tool simply takes a business job description written in natural language as an input, and then designs an entity relationship diagram with some smart rules. We introduce the scope of the proposed agent and its detailed logics with several examples. And then, we verify the appropriateness of the resulted associations among objects. Lastly, we perform case studies to evaluate the devised agent's applicability to a business field.

The purpose of this study is to analyze the actual operation status of the financial performance target management system which is currently operated and to provide improvement plan based on this analysis. For this purpose, I examined the performance management system and performance indicators of the Ministry of Justice, which is one of the criminal justice administration agencies. Although the overall appropriateness of the current performance management system is considered to be somewhat appropriate as a whole, there is a negative perception about the performance measurement method for measuring the achievement of the performance target, and the evaluation of the performance of the performance target is relatively low. In addition, there were many criticisms about the establishment and measurement of the Ministry of Justice's overall performance indicators, such as the tendency to select indicators that are easy to achieve and easy to measure. In order to remedy these problems, it was highly suggested that the importance of indicators should be more emphasized and expanded so as to set up high-performance indicators. Based on the results of this analysis, some suggestions for policy implications and some alternatives for improvement of financial performance target management system were suggested.

The strut-tie model approach has proven to be effective in the ultimate analysis and design of structural concrete with disturbed regions. For the reliable analysis and safe design of the structural concrete, however, the effective strengths of concrete struts must be determined accurately. In this study, the equations of the effective strengths of concrete struts, which are useful for the three types of determinate and indeterminate strut-tie models of reinforced concrete corbels, were proposed. The effects of shear span-to-effective depth ratio, the vertical-to-horizontal force ratio, and flexural and horizontal shear reinforcement ratios were reflected in the development of the proposed equations. To examine the appropriateness of the proposed and existing equations, the ultimate strengths of 243 reinforced concrete corbels tested to failure were evaluated by using the three types of corbel strut-tie models.
