  • The purpose of the present study was to analyze the pulpal tissue reactions to several capping materials. 8 adult Mongrel dogs and 4 different capping materials (G I : Calcium hydroxide, G II : Bonding resin, G III : Glass ionomer liner, G IV : Bioactive ceramic) we-reused in the study. The results can be summarized as follows : 1. The formation of hard tissue barrier was observed to begin after 2 weeks in all groups with various forms or positions. 2. According to the result of statistical analysis, G I and G IV showed significantly higher degree of inflammation than G II, G III in 1-week samples(p<.05). And in 2-week samples, G I showed higher degree of inflammation than G II, G IV with statistical significance(p<.05). Howere, these inflammatory reactions have gradually dimiished with time resulting in negligible difference between groups. 3. No bacterial penetration was observed in any group. 4. Hard tissue formation was evident in all groups after 2 weeks regardless of material type in this experiment. Conclusion can be drawn from the above-mentioned results that the perfect marginal sealing after pulp capping procedure is thought to be the most important factor in determining the propgnosis of direct pulp capping.

  • This study attempts to analyze some determinants of consumers' medical service quality and their complaining behavior. The results can be summerized as follows: 1. The determinants of consumers' perceived medical service quality could be categorized as five factors; i.e. nursery, hospital environment, medical doctors, other staffs service fee. Among them nursery sector consists of 32% variance. 2. According to the discriminant analysis, those determinants are of great value to distinguish between satisfied/unsatisfied group. The hit ratio was 85.4% which is relatively high score. 3. The type of complaining behavior could be grouped into no action, private and public complaining behavior. Most of respondents belonged to no action group and a few showed private complaining behavior. Any respondents who were willing to show public complaining behavior could not be found out. 4. These variables which influence complaining behavior were preconception toward hospital, barrier to complaining process and expected complaining behavior. Among them the first one was most influential variable. 5. In order to distinguish between complaining/non complaining behavior group, discriminant analysis was done. The result showed the above three variables had a significantly discriminatory power, the hit ratio reaching above 70%. In summary, we can see that consumers' evaluation on the whole medical service depends on the external factor such as staffs' attitude or hospital facilities due to the lack of their ability to evaluate highly specialized service like doctor's treatment.

  • The purpose of this study was to identify the relationship between self-efficacy and adherence of aquatic exercise in patients with chronic arthritis. Subjects were 54 patients with rheumatoid arthritis and osteoarthritis who had participated in the 6-week aquatic exercise program. The results indicated that the relationship between self-efficacy and aquatic exercise adherence in patients with chronic arthritis was statistically significant. A significant difference of self-efficacy was found between adherers and non-adherers and self-efficacy of adherer was higher than that of non-adherer(t=5.21, p=.000). Self-efficacy was significantly associated with the total duration of an aquatic exercise adherence(r=.44, p=.001). Based on these results, self-efficacy was the important factor which affect adherence of aquatic exercise in patients with chronic arthritis. Further study was suggested to identify the relationships among self-efficacy, exercise barrier and other possible factors.

  • Surface protein internalin (InlA) is a major virulence factor of the food-borne pathogen L. monocytogenes. It plays an important role in bacteria crossing the host's barrier by specific interaction with the cell adhesion molecule E-cadherin. Study of this protein will help to find better ways to prevent listeriosis. In this study, a monoclonal antibody against InlA was used to detect InlA. The reaction was label-free and monitored in real time with an oblique-incidence reflectivity-difference (OI-RD) technique. The kinetic constants kon and koff and the equilibrium dissociation constant Kd for this reaction were also obtained. These parameters indicate that the antibody is capable of detecting InlA. Additionally, the results also demonstrate the feasibility of using OI-RD for proteomics research and bacteria detection.

  • Purpose: This study was done to develop a model which explains factors influencing health promotion behavior in women who immigrate to Korea for marriage, and to verify the appropriateness of the model. Methods: The participants were 300 women who immigrate to Korea for marriage and settled in located in Jeonbuk Province, Korea. The data were collected with self-report questionnaires from October 10, 2007 through November 10, 2007. A total of 271 data sets were analyzed using the SPSS/WIN 12.0 and Amos 7.0 version. Results: Immigrant women's social support, self-efficacy, perceived health status, acculturation, and perceived barrier had an impact on their health promotion behavior. Social support was the most influential factor. All of these variables together explained 49% of the variance in health promotion behavior in immigrant women married to Korean men. Conclusion: In order to increase the health promotion behavior in immigrant women, intervention strategies to increase social support and self-efficacy for immigrant women should be developed.

  • The analysis of the thermal boundary resistance is very important in the both cases of microscale and macroscale systems because it plays a role of thermal barrier against a heat flow. Especially, since fairly large heat energy is generated in microscale or nanoscale systems with electronic chips, the thermal boundary resistance is a key factor to guarantee the performance of those devices. In this study, the transfer of the oscillator's motion information with 2 degrees of freedom is investigated for clarifying the mechanism of a thermal boundary resistance. We found that the transfer of the oscillator's motion information is defined as a cross-correlation coefficient and the magnitude of it determines the temperature jump over a solid interface. That is, the temperature jump over an interface increases as the magnitude of a cross-correlation coefficient decreases and vice versa.

  • The need for this study must be considerable, as being activate of green roofs research that the organization and construction obtain access to more development technologies. Nevertheless, the green roofs system has begun to apply since 1980's, the green roofs technology was restricted to develop without verification of technologies such as a load or water leakage. There is a limit as urethane waterproofing to almost domestic waterproofing materials and methods of construction for general green roofs. The introduction of materials and methods of construction which are appropriated to property of green roofs could be a decisive factor in a long-range durability and economical maintenance cost, moreover, it support to variety construction system and organization. This present paper describes a necessity of waterproofing and root barrier system is one of the sub-organization based on green roofs construction, which have enormously large impact on the durability.

  • Construction industry is overwhelmed by delay and often has suffered cost and time overrun. In this context, Last Planner System (LPS) has been considered as a very useful tool for the management of the construction process. Many previous studies have reported its effectiveness in construction performance. This study aims to evaluate the level of importance of the Last Planner processes in the Vietnam construction industry (VCI), and analyze the existing barriers when implementing these processes in construction management. These barriers were collected based on previous studies from International Group for Lean Construction (IGLC). A survey was carried out through questionnaire. The respondents are been experienced people in construction project management. There are four processes of LPS that were investigated including master schedule, phase schedule, lookahead plan, and weekly work plan. The results showed that master schedule is the most important item when performing a construction project in the VCI. The highest degree of agreement belongs to 'owner - contractor' pair with 77.1% importance indices; whereas the lowest belongs to 'consultants - contractors' pair with 63.8% importance indices. Eventually, three barrier factors were extracted from factor analysis technique with 62.2% of variance explained.

  • With the basic research logic stating that the systematic improvement of rural housing plot's boundary barriers should call for the integrated consideration of their on-and-around installing settings, this study tries to analyse characteristics of installing environment of boundary barriers for improvement works of them. Through literature review and then screening process, 3 influencing and appraisal factors were determined: main house-boundary barrier shortest distance as on-site factor, building coverage as inside one, and attached road width as outside one. 21 study villages were subgrouped into structurally improved(9) and not(12). Site investigation and analysis results showed that the relationship between factors has varied very much, i.e. in some cases it is positive or complementary, but in other cases, negative or crossed. Therefore this study would propose that differentiated and flexible strategies with integrated consideration of on-and-around site installing settings be applied in their improvement projects rather than village-wide unified or straight forwarded ones.
