In times of current warfare, importance of civil military operations(CMO) is more on the rise because the military winning does not couple the political winning immediately. For this reason, CMO Model Development Program has been commenced by ROK JCS since FY 2014. As CMO is non-kinetic operations which is focused on civilians, it depends on the commander's decision that reflects the results of the evaluation of the CMO performance level. The evaluation of CMO performance level is a very important factor of this model. So, I decided my subject a study of simulation method for evaluation of CMO Performance level. It is affected in CMO performance level by the occurrence of some event, and the achievement results of CMO for the response action on such event is evaluated by the 5 factors(administration level, security level, infrastructure level, humanitarian support level, friendship level) on the evaluation of CMO performance level. Even more it is affected in achievement of new CMO and new event by evaluation results. In this study, I provided a methodology of how apply the evaluation results and how simulate the achievement results of CMO performance with the 5 factors on the evaluation of CMO Performance level. Also this study is expected that it will be highly contributed to training and exercise in CMO branch in ROK JCS, when CMO Model Development Program is done as a new model applied such evaluation factors matching military environment in the Korean Peninsular, and applied this simulation method for evaluation of CMO Performance level.

For accurate impression taking, accurate impression material, solid individual tray, and bond strength between impression materials and resin tray are important factors. The purpose of this study was to evaluate tensile bond strength of rubber impression materials to various tray resin materials. This study tested the time dependent tensile bond strength between commercial brands or poly ether, polysulfide, additional silicone impression materials and commercial brands of self curing tray resin. light activited tray resin when applying adhesive Resin specimens were made with 20mm in diameter, 2mm in thickness. 1 made total 360 specimens, 10 per each group and the tensile bond strength was measured by using the Instron($M100EC^{(R)}$, Mecmesin Co., England). The results were as follows ; Comparisons of various impression materials. 1. In case of Impregum $F^{(R)}$, the bond strength of tray resin was decreased in order of SR $Ivolen^{(R)}$, Ostron $100^{(R)}$ Instant tray $mix^{(R)}$, $Lightplast^{(R)}$. All groups excluding Ostron $100^{(R)}$, Instant tray $mix^{(R)}$ are significant difference (p<0.05). Drying time after applying adhesive, the tensile bond strength of tray resin was insignificantly decreased in order of 10 min drying time group. 1 min drying time group. 5 min drying time group. 2. In case of Permlastic $regular^{(R)}$ the bond strength of tray resin was insignificantly decreased in order of Ostron $100^{(R)}$. SR $Ivolen^{(R)}$, Instant tray $mix^{(R)}$ $Lightplast^{(R)}$. About drying time after applying adhesive, the tensile bond strength of tray resin was significantly decreased in order of 5 min drying time group, 10 min drying time group, 1 min drying time group(p<0.05). 3. In case of Exaflex $regular^{(R)}$. the bond strength of tray resin was decreased in order of $Lightplast^{(R)}$, SR $Ivolen^{(R)}$, Instant tray $mix^{(R)}$, Ostron $100^{(R)}$. $Lightplast^{(R)}$ was significant difference(p<0.05). About drying time after applying adhesive, the tensile bond strength of tray resin was decreased in order of 5 min drying time group, 10 min drying time group, 1 min drying time group(p<0.05). Especially 5 min ding time group was significant difference(p<0.05). According to the results of this study, we can see the greatest tensile bond strength when using Impregrm $F^{(R)}$ and Permlastic $regular^{(R)}$ with self curing tray resin, when using Exaflex $regular^{(R)}$ with light activated tray resin In my opinion, adhesive should be dried more than 5 min before impression taking to achieve the greatest tensile bond strength.

The purpose of this study is to investigate the change and structure of the altitudinal vegetation on the east side of Hallasan National Park, and to accomplish this research, seventeen plots($400m_2$ per zone) were set up along the Seongpanak trail starting from 750m to 1,450m(which was 700m long). These zones, according to the two-way indicator species analysis(TWINSPAN) and ordination analysis(DCA), were divided into six communities: Carpinus tschonoskii-Stryrax japonica community(I), Stryrax japonica-Quercus serrata community(II), Carpinustschonoskii-Q. serrata community(III), Q. mongolica-C tschonoskii community(IV), Acer pseudosieboldianum community(V), and Q. mongolica-Abies koreana community(VI). The findings of my investigation are as follows: the altitudinal vegetation structure of all the investigated zones from 750m to 1,000m above sea level is similar to one another, whereas the same zones from 1,000m to 1,450m above sea level showed dissimilarities among them. That indicates that altitudinal vegetation structure on the east side of Hallasan National Park has changed drastically at the 1,000m areas above sea level, and the forest age of this area is over 50 years.

In this study, nano-micelled curcumin was produced with natural sea salt with a view to comparing the in silico molecular binding affinity of pure curcumin compound to the active site of transthyretin. Using an optical light microscope and an electron microscope, it was found that the structure of the surface and the cross-section of nano-micelled curcumin was significantly different from natural sea salt. In particular, the crystal structure and nano-components in the nano-micelled curcumin were united, and the layer was more strongly stabilized than untreated salts. In the virtual 3D structure, in silico molecular docking study, the ligand binding affinity of nano-micelled curcumin to the transthyretin active site was found to be higher than that of pure curcumin. In addition, a nano-micelled curcumin formula interacted with more amino acid residues of transthyretin domains. The pharmacophore feature of the nano-micelled curcumin also showed more condensed and constrained features than normal curcumin. These results suggest that nano-micelled curcumin may effectively bind to and stabilize transthyretin, thereby regulating transthyretin-related physiological diseases. Collectively, the nano-micelled curcumin process suggests that normal curcumin can be modified more efficiently into the novel bio-functional chemical formula to stabilize the transthyretin structure. Therefore, the nano-micelled curcumin process can be applied to the field of the regulation of Alzheimer's disease.

This study, from a critical view on knowledge-centered science education, aims to explore the wisdom that can be acquired from science. In other words, to find the categories and examples of "Wisdom of Science(WOS)" that can be shared in science classroom is the purpose of this study. For the data collection, twelve hours of physics classes of three high schools were observed, together with teacher interviews and student interviews. Collected data were analyzed qualitatively based on the operational definition of WOS. In this study, WOS was defined in a limited sense to mean 'wise action such as behaviors, attitudes, methods, and thoughts that can be found in the process of formation and application of scientific knowledge'. The results of this study, i.e. three categories and six examples of WOS, can be summarized as follows. First category of WOS is 'wisdom as a scientific attitude'. The examples of this category are 'rational suspicion and open-minded attitude', and 'effort to find the best way in given situation'. Second category of WOS is 'wisdom as a method for problem solving'. The examples of this category are 'thinking with changing the conditions', and 'communication using the language of science'. Third category of WOS is 'wisdom as a reflection about science and human'. The examples of this category are 'understanding of the relationship between science and society', and 'perceiving the relationship between science and my life'. In conclusion, "Wisdom-oriented Science Education" as an alternative goal of future science education is suggested with its meanings and implications.

This study aims to empirically measure K-pop fans' content and the extent of online activities. To achieve the purpose of the study, the researchers identify the statistically significant online activities that determine the intensity of fan attachment toward K-pop artists. Further, the research confirms the relative importance of various meaningful online activities. Consequently, we can develop the K-pop Online Activity Index (KOAI) model and apply it to this index model empirically for each respondent. We found that the model consists of five online activities of K-pop fans: whether joining the fan club or not, whether paying per view V live+ or not, whether watching VODs associated with artists or not, the degree of fan club writing, the degree of watching a lot on YouTube to improve the value of my artists. This study has practical significance in that it allows K-pop marketers to improve their marketing performance by providing content that will enable them to more efficiently and effectively allocate marketing resources to various online activities to get fan responses. It allows accumulating academic knowledge to understand the behavior in the field of online behavior for K-pop fans.

This study examined the difference between mindfulness and psychological well-being of art psychotherapists according to their demographic characteristics. The subjects were 127 art psychotherapists working at counseling centers in Ulsan metropolitan city. Statistical software R was used for frequency analysis, factor analysis, reliability analysis, independent-sample T-test, and one-way ANOVA. A Scheffe test was used for post hoc analysis. The results showed that the difference in mindfulness of art psychotherapists was significant in age and at peer supervision and case study meanings in supervision type only. Second, the difference in the psychological well-being of art psychotherapists was significant at peer supervision and case study meetings in supervision type only. This means that the more art psychotherapists experience peer supervision and case conferences, the more they perceive mindfulness and psychological well-being. These results suggest that age and supervision type are important for the art psychotherapists' mindfulness and psychological well-being. Therefore, to improve artistic psychotherapists' mindfulness and psychological well-being, it is necessary to systematically develop and operate support programs for each developmental stage to improve artistic psychotherapists' demographic characteristics and professional development.
