Purpose: The purpose of this study is to determine the importance and priority arising from the relationship between MRO-office supplies franchisor ("franchisor") and franchisees through an in-depth investigation. In particular, with respect to the MRO-Office franchise industry, we would like to make meaningful contributions in the decision-making process by comparing and contrasting factors that affect the importance and priority of communication, conflict, support and satisfaction through AHP analysis. Research design, data, and methodology: After completion of AHP analysis, the study will also identify factors in order of priority and factors of importance between the franchisor and franchisees. Another purpose of this study is to evaluate and propose business relationship strategies between the franchisor and franchisees. Through AHP analysis, this study will facilitate the relationship between the franchisor and franchise, and determine the factors of importance and factors in order of priority. Result: This study evaluates the differences and priorities of the two groups arising from the relationship between the franchisor and the franchisees through AHP analysis after separately analyzing the franchisor. In this study, the franchisees find that communication is the most important factor, then support as the second most important factor between the two groups. In contrast, the franchisor finds that support is the most important factor followed by communication between the two groups. Conclusions: This analysis demonstrates the discrepancy in evaluating important factors from the perspectives of the franchisor and the franchisees. The largest discrepancy between the franchisor and franchisees comes from an information system related to communication factors. This effectively means that the franchisor has an understanding of this inadequate information system on the part of franchisees but this understanding is not deemed an important factor. The franchisees recognize and focus on the need to obtain feedback from the franchisor regarding management improvement as the most important factor rather than the ability of the franchisor to guide them through the franchisees' operations. To this end, the franchisor should be more flexible in dealing with the problem of improving the work required by the franchisees. For this study, a survey was conducted on employees of MRO-office supplies franchisor, franchisees, and employees and completed based on AHP analysis.

High-rise buildings (HRBs) are considered one of the most common structures nowadays due to the population growth, especially in crowded towns. The lack of land in crowded cities has led to the convergence of the HRBs and the absence of any gaps between them, especially in lands with weak soil (e.g., liquefaction-prone soil), but then during earthquakes, these structures may be exposed to the risk of collision between them due to the large increase in the horizontal displacements, which may be destructive in some cases to the one or both of these adjacent buildings. To evaluate methods of reducing the risk of collision between adjacent twin HRBs, this research investigates three vibration control methods to reduce the risk of collision due to five different earthquakes for the case of two adjacent reinforced concrete (RC) twin high-rise buildings of 15 floors height without gap distance between them, founded on raft foundation supported on piles inside a liquefaction-prone soil. Contact pounding elements between the two buildings (distributed at all floor levels and at the raft foundation level) are used to make the impact strength between the two buildings realistic. The mitigation methods investigated are the base isolation, the tuned mass damper (TMD) method (using traditional TMDs), and the pounding tuned mass damper (PTMD) method (using PTMDs connected between the two buildings). The results show that the PTMD method between the two adjacent RC twin high-rise buildings is more efficient than the other two methods in mitigating the earthquake-induced pounding risk.

Purpose : Genu varum is a condition characterized by a wider than normal gap between. This may be due to muscle weakness caused by poor posture, lifestyle, or lack of exercise. This study aimed to compare the effects of ball-based squats and narrow squats on muscle thickness, Q-angle, and the gap between the knees, in order to assess the potential for improving this condition. Methods : Twenty six adult participants with genu varum were randomly assigned to either a ball-based squat group (n=13) or a narrow squats group (n=13). Both groups performed their respective exercises three times weekly for 4 weeks. The data was analyzed using paired t-tests to compare pre- and post- intervention measurements within each group, and independent t-test was used to compare the two groups. Results : Both groups showed significant improvement in the thickness of the vastus lateralis and medialis, and rectus femoris muscles, as well as a significant decrease in the gap between the knees (p<.05). However, there was no significant difference in Q-angle variation between the two group. Furthermore, there was no significant differences in the Q-angle, gap between the knees, and muscle thickness variation between both groups. Conclusion : The results suggest that both ball-based squats and narrow squats are effective in improving muscle thickness and reducing the gap between the knees in adults with genu varum. However, there was no significant difference between the two types of squats in terms of their effects on the Q-angle. These findings highlight the potential for exercise interventions to address this common postural issue.
The purpose of this study was to propose a policy development plan for win-win growth between franchisor and franchisee by investigating success factors of win-win growth on the basis of the problems between franchisor and franchisee. There are many small scale franchise businesses in Korea that have not achieved an economy of scale compared to the developed countries. The conflicts between franchisor and franchisee have continued due to a lack of social trust which comes from an excessively high ratio of business failure and big firms' expansion into franchise business, then again, the perception of relations between the topdog and the underdog causes many problems. As franchise is the industry based on common people that helps service industry advance and competitiveness of the self-employed improve, it needs to be activated as the higher value-added business by promoting establishment of business and strengthening foundation of related industry. A matter of mutual cooperation and win-win growth between franchisor and franchisee is important not only for the sound development of franchise industry but also for the stable growth of nation's economy. Thus, this study suggested a policy development plan for win-win growth between franchisor and franchisee by analyzing success factor of win-win growth based on the problems between franchisor and franchisee. The results of the study provide the important strategic way towards mutual growth and maintaining cooperative relationship between franchisor and franchisee in Korean franchise industry.
Objective: To assess the potential clinical utility of in-vivo 31P magnetic resonance spectroscopy (MRS) in patients with various malignant and benign breast lesions. Materials and Methods: Seventeen patients with untreated primary malignant breast lesions (group I), eight patients with untreated benign breast lesions (group II) and seven normal breasts (group III) were included in this study. In-vivo 31P MRS was performed using a 1.5 Tesla MR scanner. Because of the characteristics of the coil, the volume of the tumor had to exceed 12 cc (3×2×2 cm), with a superoinferior diameter at least 3 cm. Mean and standard deviations of each metabolite were calculated and metabolite ratios, such as PME/PCr, PDE/PCr, T-ATP/PCr and PCr/T-ATP were calculated and statistically analyzed. Results: Significant differences in PME were noted between groups I and III (p=0.0213), and between groups II and III (p=0.0213). The metabolite ratios which showed significant differences were PME/PCr (between groups II and III) (p=0.0201), PDE/PCr (between groups I and III, and between groups II and III) (p=0.0172), T-ATP/PCr (between groups II and III) (p=0.0287), and PCr/T-ATP (between groups II and III) (p=0.0287). There were no significant parameters between groups I and II. Conclusion: In-vivo 31P MRS is not helpful for establishing a differential diagnosis between benign and malignant breast lesions, at least with relatively large lesions greater than 3 cm in one or more dimensions.

The contact pressure between the surrounding rock and the support is an important indicator of the surrounding rock pressure. There has been a bottleneck in the prediction of contact loads between surrounding rock and primary support in deep-buried mountain tunnels. The main reason is that a reliable method wasn't existed to quantify the contact loads. This study had been taken into account the flexible support role of the primary support, and the fitting curve of surrounding rock deformation for dynamic tunnel construction was proposed. New formulas for the calculation of contact loads between surrounding rock and primary support were obtained by inversion. Comparative analysis of the calculation results with numerical simulation verified the reliability of the calculation method in this study. It can be seen from the analyses that the contact load between surrounding rock and primary support increases, remains unchanged and decreases during acceleration, uniform velocity and deceleration, respectively, and the deformation of the surrounding rock in the acceleration and deceleration stages cannot completely converted into contact loads. The contact loads between surrounding rock and primary support of medium-strength and weak surrounding rock tunnels are generally within 150 kPa and 1 MPa, respectively. For tunnels with weak surrounding rock, advanced support can be installed to reduce the unique release coefficient λ0 and the value of the constant D, with the purpose of reducing the contact loads between surrounding rock and primary support. Changes in support parameters have a small effect on the contact loads between surrounding rock and primary support, but increase or decrease the safety factor, resulting in a waste of resources or a situation that threatens the safety of the support. The results of this research provide guidance for the prediction of contact loads between surrounding rock and primary support for dynamic tunnel construction.
In this paper, the increment of the local scour depth at piers by constructing the bridge between existing bridges is examined through the experiments in which 5 piers in the non-cohesive bed material in the experimental flume were installed. In the experiments the maximum distance of 25 times of the pier length and the maximum distortion width of 8 times of the pier width were utilized. Through the experimental studies, it was indicated that low flow, which can be characterized as the flow having low Froude numbers, the maximum bed configuration change is obtained when the piers are installed in the straight line in the flor direction without any distortion. However, In the high flow, which can be characterized as the flow having high Froude numbers, the maximum bed configuration change is obtained when the piers are installed with some distortion from the flow direction. The influence of the bed configuration by interaction between bridge piers is changed depending upon the Froude numbers, the distance between piers, and the distortion width between adjacent bridge piers. Also, because the scour patterns are affected by the bed configuration, the maximum scour should be increased by about 60% compared to that in a single pier if the interaction between bridge piers exists. It can be suggested that the maximum scour depth at bridge piers predicted by applying the existing equations should be increased if the interaction between bridge piers exist. Those cases are found when new bridges are constructed successively in the river in the urban area.
Taking an opportunity of the application of clearcutting method, 140 red pine (Pinus densiflora Sieb. et Zucc.) trees grown at Chon-nam province, the southern part of South Korea, were fellen and the tree height, clear-bole length, D.B.H. diameter at base(0.2m above from the ground line) and the length of the longest branch were measured. The correlation between factors mentioned were analysed. The results are summarized as follows: 1. The correlation between crown length and tree height (r=0.821) was sinificant. 2. The correlation between the diameter at base and D.B.H. was highly significant (r=0.961). D.B.H. can be calculated from multiplying the diameter at base by 0.88. 3. A weak relation between D.B.H and tree height was abserved. 4. The positive correlation between tree height and clear-bole-length was calculated, but it was not sharp between D.B.H. and the length of the longest branch. 5. The height, basal area, D.B.H. and volume increment by tree class calculated from the data of the stem analysis are presented (Tab. 3~10).
The present study was carried out for the period from July 14 through September 13, 1975 by means of questionnaire distributed to 300 nursing students whose extent of satisfaction is known to be relatively low compared with other students of the different course of study by applying the perceptual orientation scale based on the principle defining that the effectiveness in maintaining helpful relation with others in human society depends upon the perception possessed by individuals, The present study was intended to investigate the effectiveness of nursing profession for nursing students of the 4- year system and 3- year system nursing school and relationship between perceptual orientation and clinical achievements, thereby, attempting more efficient application of the perceptual orientation scale. The results obtained are summarized as follows : 1. There was observed no significant difference in perceptual orientation between the nursing students of the 4- year system and 3- year system nursing schools. 2. There was observed significant correlation between the perceptual orientation and clinical achievements of the nursing students. 3. In the comparison of the perceptual orientation Point and mean value by school significant difference was observed between schools other than B and C schools of the 4 - year system. 4. Marked correlation was observed between the perceptual orientation and clinical achievements of the students of 4 - year system nursing courses. 5. Low correlation was observed between the perceptual orientation and clinical achievements of the students of the 3- year system nursing school.
This study was designed to investigate the effects of information by using cartoon on preoperative anxiety of children following tonsillectomy. The subjects were 30 children aged between 7 and 12 who were hospitalized at C university hospital for undergoing tonsillectomy from December 20, 1996 to August 14, 1997 Sixteen of them were assigned to the experimental group, while fourteen subjects to the control group. The data were collected through preoperative state anxiety, pulse rate, pain before and after giving information by using cartoon. The results were as follows : 1. Preoperative state anxiety increased in both groups (P=0.0348). No significant difference found between experimental and control group. But preopertive anxiety in experimental group was apt to increase less than that in the control group. 2. Pulse rate didn't make significant difference within and between groups. 3. Pain increased in both groups (P=0.0001). No significant difference found between experimental and control group. 4. Experimental group between the aged 7 and 9 decreased preoperative state anxiety, but experimental group between the aged 10 and 12 increased preoperative state anxiety after treatment(P=0.0298). These findings may indicate that the information by using cartoon is effective in children between the aged 7 and 12.
