There are three important components in tissue engineering: the cells, signaling factors (cytokines and growth factors), and scaffolds. To obtain finely engineered tissue, all three components should perform their individual functions and be fully integrated with each other. For the past few years, we have studied the characteristics of photodimerizable HA (CHA)/alginate (CA) composite materials. CHA/CA complex hydrogels, which were irradiated under UV light and, then treated with calcium ions, were found to have good biocompatibility, mechanical properties and water resistance for implantable tissue scaffolds. In this study, we introduced a cell growth factor (basic fibroblast growth factor; bFGF) into the CHA/CA scaffolds and studied its release behavior. We also introduced tetracycline hydrochloride and flurbiprofen into the same scaffolds as model activation factors and evaluated their release behaviors from the scaffolds. The drug release rate from the materials was influenced by various parameters, such as the degree of crosslinking, the cross linker type, the physico-chemical properties of the drug, and the amount of the drug in the polymer. The results indicated that the negatively charged CHA/CA composite materials showed sustained release behavior and that HA has a particularly strong negative charge, making it attractive toward tetracycline hydrochloride and bFGF, but repulsive toward flurbiprofen.

Purpose: This study explored the relationships among resilience, job stress, and organizational commitment in ICU nurses. Further, the possibility of the application of resilience to the hospital environment was evaluated to provide basic data for program development to improve resilience and to promote nurses' commitment to their organizations. Methods: Data were collected from 174 ICU nurses at A University Hospital. The cross-sectional descriptive survey was conducted using a structured questionnaire. Results: The mean resilience score was $2.41{\pm}0.47$ out of 4. The mean score for job stress was $3.60{\pm}0.36$ out of 5, and that for organizational commitment was $3.25{\pm}0.55$ out of 5. Analysis of the relationships between the participants' resilience and organizational commitment indicated a significantly positive correlation (r=.45, p<.001). According to the general characteristics, organizational commitment levels showed a significant difference according to the ICU type (F=1.38, p<.001). Conclusion: It may beconcluded that the important individual factor of resilience had a positive influence on organizational commitment. Thus, resilience should be actively promoted, and a program should be developed to enhance the resilience of ICU nurses.

This study is purposed on applying to certifying environmental-friendly buildings about remodeling schools as an issue recently, keeping up a worldwide resource conservation movement. Application standard is directed, comparing with systems certifying green-schools in domestic and foreign policies. The following is the primary result of this study. First, on developing systems for certifying environmental-friendly buildings about remodeling schools, characteristics like ‘the phase of certifying essential lists and the diversity of certifying lists’, ‘developing departmentally into new-building, reconstruction, remodeling, existing-building in basic data’, ‘development of certifying existing-buildings as well as new-building’ in foreign systems should be developed appropriately for Korea. Next, not only reuse of the existing facilities but better assessment through diversification of classified contents in domestic system are carried out in comparing remodeling lists. Especially the primary list that is found out commonly limited lists certifying remodeling should be developed appropriately. Impossible lists getting certification should be applied to map out a concrete standard. Lastly, the range of certification should be diversified and developed sustainable like other systems for better assessment. Adding various lists suiting for Korea and departmentalizing score of phases and items in particular, for avoiding a needless collision between certification lists, absence of them. Above of all, basic direction about certifying environmental-friendly buildings about remodeling schools should be developed the only individual instrument, not for gaining it simply as a part of the environmental policy in Korea. This study has significance on vitalization of certifying environmental-friendly buildings, which performing primary environmental-friendly education facilities, based on its advance.

The running condition of multi-system air conditioner is prone to vary largely as it is designed for individual conditioning in each space of middle and small sized buildings. This leads to overcooling in case of partial load run, while the lack of capacity happens in case of full load run. Besides these, there exist such problems as instabilities due to the uneven refrigerant distribution caused by fluctuation of load and the change in piping line. Based upon the basic study on the function characteristics found in parts needed for maximized system working design in order to troubleshoot, the system functioning pattern should be identified through the different tests with various operating circumstances and the analysis models should be developed. With this ground, the control logic has to be made to have a control over capacity and make possible the efficient distribution of refrigerant.

As various styles of fonts were used, there were problems such as output errors due to uninstalled fonts and difficulty in font recognition. To solve these problems, research on font recognition and recommendation were actively conducted. However, Hangul font research remains at the basic level. Therefore, in order to automate the comparison on Hangul font similarity in the future, we analyze the influence of each stroke element property. First, we select seven representative properties based on Hangul stroke shape elements. Second, we design a calculation model to compare similarity between fonts. Third, we analyze the effect of each stroke element through the cosine similarity between the user's evaluation and the results of the model. As a result, there was no significant difference in the individual effect of each representative property. Also, the more accurate similarity comparison was possible when many representative properties were used.

In the metaverse, it is important to embellish aesthetics of user with a character called 'Avatar', a virtual representation of the user. This study provides basic data related to the fashion trend of the metaverse by studying 'Zepeto', a representative Korean platform. For empirical research, Zepeto's "Best Items" section were investigated and analyzed in the first pre-survey. Based on this, the second and main survey was conducted using a questionnaire to investigate users' style-specific preferences and purchasing behaviors for virtual fashion, comparing style preferences between virtual and real, brand preferences, and purchasing behaviors of virtual fashion. The survey found that most users were teenage girls with a high preference for pastel-toned, feminine, and cute casual styles who had a much higher interest in brands bearing idol names than in real-world luxury brands. Many responded that they felt burdened by purchasing items that had to be purchased for cash. The same can be assumed to be the reason why they preferred a suit of items that were fully coordinated rather than individual items. These results seem to reflect characteristics of teenage girls who lack cash with a high preference for idols and feminine-cute casual styles. This study suggests considerations when creating virtual fashion items. By providing basic information, more effects and developments in creating virtual fashion items that reflect consumer preferences and reactions are expected in the future.

The building energy audit is an important process when collecting basic information for improving the energy performance of existing buildings. Audit parameters should be associated with the energy performance of the building. Such audit parameters will vary according to an individual building's characteristics and energy consumption patterns, but most building energy audits are performed in the same way. The sensitivity analysis (SA) is a statistical method to quantify the correlation between inputs and outputs that can determine which input is influential to which output. Therefore, an SA can identify influential parameters when applied to building energy analysis. In this paper, we adopted the Morris method to identify building energy audit parameters and performed a Monte Carlo simulation for uncertainty analysis. As a result, this method was able to identify an influential parameter for building energy audits and reduce uncertainty in energy consumption in buildings.

Purpose: This study was to identify the relations of interpersonal attitude and communication competence of new community health nurses. Methods: The research design was a correlational study. The data were collected from 136 visiting nurses using a structured questionnaire and analyzed using independent t-test, Pearson's correlation coefficient, and multiple regression with the SPSS/WIN 20.0 program. Results: The type of interpersonal attitude in subjects was I+U+ and the score of communication competence was 3.6. Among 15 sub-dimensions, the highest score was responsiveness and the lowest was assertiveness. There were no significant differences in communication competence by general characteristics. Factors influencing on communication competence in new visiting nurses were interpersonal attitude I+(I am OK) (${\beta}$=.34) and I-(I am not OK) (${\beta}$=-.28). Conclusion: Education program, stressing the self-awareness, is necessary to increase positive interpersonal attitude and communication competence for reemployment of community health nurses. Furthermore, in order to reinforce assertiveness, institutional support should be accompanied with the efforts of individual level.
