Functional oils (FOs) were produced from commercial diacylglycerol oil and red yeast rice extracts from 80% ethanol for 1 hr in a shaking water bath at $35^{\circ}C$ and 175 rpm. FOs contained (A) 600, (B) 1200, (C) 1800, and (D) 2280 ppm of red yeast-rice extracts, respectively. The Hunter a value and b value were risen whereas L value was reduced along with the increase of extract concentration. Content of monacolin K and total phenolic compounds in FOs significantly increased according to the increase of extract concentration. The oxidation stability of FOs was observed by Rancimat at $98^{\circ}C$. Induction time decreased according to the increase of extract concentration. The major volatile compounds of FOs were compared using the electronic nose (EN) system and solid phase microextraction (SPME) method combined with gas chromatograph/mass spectrometry (GC/MS). EN was composed of 12 different metal oxide sensors. Sensitivities (Rgas/Rair) of sensors from EN were analyzed by principal component analysis (PCA), whose proportion was 99.66%. For qualitative or quantitative analysis of volatile compounds by SPME-GC/MS, the divinylbenzene/carboxene/polydimethyl-siloxane fiber and sampling temperature of $50^{\circ}C$ were applied.

By comparing and analyzing the September 11 terror attack news reports on the daily papers in the U.S., Korea, and China, this research found that national ideology and international relationship concerned have affected news report frames about international dispute matters. Both quantitative and qualitative researches identify differences in news framing. For example, after the September 11 terror attack, the most pages of the USs The New York Times and Korean Chosunilbo were covered with related articles(382 and 192 reports, respectively), whereas Chinese Inminilbo cur down to only 32 reports about the issue. Also in content, both The New York Times and Chosunilbo viewed the September 11 terror attack as evil acts which threatened world peace and justified military action against Afghanistan as inevitable revenge and justice for such evil acts, in the point of the USs official view. However, Inminilbo gave out news only based on facts in a neutral viewpoint. Moreover, regarding American military intervention, the Chinese newspapers held very different news frame from the other two by describing considerable sacrifice and pain of innocent people of Afghanistan seriously. For the story composition, daily newspapers in all three countries took the same way to report focusing on specific events with episodes.

The presence and content of residual hexane in the olive oils were studied. Total 41 olive oils of imported and domestic brands, which were labeled as extra virgin and refined (mixed), were collected from the market. For analysis, electronic nose and headspace SPME-GC/MS were used. Electronic nose equipped with 12 metal oxide sensors was used for the discrimination of odor pattern of olive oils against the different concentrations of hexane. From the results, it is assumed that the contents of residual hexane in the collected olive oils were below 5 ppm. For Qualitative and quantitative analysis of hexane, polydimethylsiloxane (PDMS) fiber was employed for SPME-GC/MS. In the results, the peak of residual hexane was detected in 8 samples from 41 olive oils. But the detected level was no more than 1 ppm that is under the regulation limit (5 ppm) by Korea Food Additive Code.

The purpose of this study is to find specific practice methods of single parents self-help groups in community welfare centers. A participatory action research was conducted to achieve the purpose. Six social workers and three researchers participated in the study who shared the problem of lack of specific practice methods even though a self-help group was useful for self-reliance and empowerment of low-income single-parents. Various activities such as reading articles, analysis of each self-help group, case studies, and learning facilitation methods were conducted during 10 meetings. At the same time, peer supervision proceeded at each meeting. The progress of each group was shared, the application of practice methods and plans were discussed, and applying discussed methods to group practice and reviewing the process and outcomes of the practice were repeated in the peer supervison. As a result, the following positive changes appeared: First, the goals and vision of each group became clearer. Second, initiative of the members was promoted. Third, intimacy, mutual cooperation, the attatchment to the group were strengthened. A qualitative analysis was also conducted on the content discussed. As a result, 17 practice methods were derived in four themes such as initiative/ empowerment, cohesion, leadership, and destandardization. Practice issues concerning single parents self-help groups in community welfare centers were discussed based on the results.

The study was a mixed design study that analyzed the effects of developing and applying a program to improve pregnancy recognition for severe low fertility. The study period was from April 1, 2018, to October 26, 2018, and the participants included 16 women of 19~21 age who lived in M City and M Gun. The process of program development is based on Dorothy Johnson 's theory of behavior system to induce change of perception, and reference literature review and national policy report. The program developed through the literature was finally developed by examining the experts panel discussion after deriving causes and alternatives for low fertility from 25 fertility women. The contents of program consist of three areas. Quantitative research results were analyzed using Shapiro Wilk and Wilcoxon sign rank using SPSS 18.0, and qualitative research results were analyzed using focus group. As a result of study, the perception of pregnancy increased significantly (P<0.01) with statistical significance as pre-experimental (M=3.21, SD=.342), post-experimental (M=4.46, SD=.398) and the result of content analysis appeared three themes as , , . In conclusion, the program was effective in improving the recognition of pregnancy for young women.

The objective of this study was to access the effect of climate and soil factors on alfalfa dry matter yield (DMY) by the contribution through constructing the yield prediction model in a general linear model considering climate and soil physical variables. The processes of constructing the yield prediction model for alfalfa was performed in sequence of data collection of alfalfa yield, meteorological and soil, preparation, statistical analysis, and model construction. The alfalfa yield prediction model used a multiple regression analysis to select the climate variables which are quantitative data and a general linear model considering the selected climate variables and soil physical variables which are qualitative data. As a result, the growth degree days(GDD) and growing days(GD), and the clay content(CC) were selected as the climate and soil physical variables that affect alfalfa DMY, respectively. The contributions of climate and soil factors affecting alfalfa DMY were 32% (GDD, 21%, GD 11%) and 63%, respectively. Therefore, this study indicates that the soil factor more contributes to alfalfa DMY than climate factor. However, for examming the correct contribution, the factors such as other climate and soil factors, and the cultivation technology factors which were not treated in this study should be considered as a factor in the model for future study.

The purpose of this study was to explore the continuing bonds experienced by adolescent victims' 15 parents of the Sewol ferry disaster. The research aim is to classify the continuing bonds into representational, functional, emotional, and relationship characteristics through contents analysis and identify them. The way dimension was found to be continuing bond through "physical objects and space," "dream and spiritual exchange," "personal memorial and ritual activities," "thoughts of deceased children," and "surviving children." In the "functional dimension," it was found that sustainable ties help families find new meanings and purposes in their lives and comfort them by making them feel they are with their children. In addition, at the emotional level, they experienced 'positive emotions' while feeling with their children, and experienced 'pain', and some research participants found it difficult to sustain the bond itself. At the level of each relationship characteristic, the relationship between parents and children was an extension of the relationship even after the child was deceased, and the relationship characteristics were reproduced. The implications for grief counseling were presented by applying a dead two-axis model to the results of this study.

The purpose of this study is to investigate the educational needs of virtual reality(VR)-based communication and teamwork skills for patient safety intended for nursing students and nurses. For this study, mixed method design was used with surveyed data collected 60 nursing students and 123 nurses. And fourteen nurses was conducted focus group interview. SPSS/WIN 25.0 and inductive content analysis for focus group interviews were utilized for data analysis. The results indicated that the awareness of VR and educational needs of team communication, and teamwork skills were above average, and nursing students required higher educational needs than nurses. Teamwork knowledge was moderate, and there was no significant difference between the two groups. Regarding nurse's communication in hospital, 4 themes of contributing factors and 2 themes of result factors that cause communication difficulties among nurses were derived from the qualitative data. Therefore, it is necessary to develop a virtual reality-based simulation program reflecting the educational needs of nursing students and nurses in order to improve team communication and teamwork skills for patient safety required for nursing students and nurses.

In this study, to explore the possibility of using discarded by-products of corn as a wrinkle-improving functional material, the active ingredient contained in each part including kernel, cob, husk, and silk of 10 varieties of chodang and waxy corn was identified and the content was analyzed to suggest the possibility of corn by-products as upcycling materials. As a result of evaluating the collagen synthesis efficacy of extracts by part, the cob in chodang and waxy corns showed significant activity at 100 ㎍/mL concentration of 176.5 and 140.0%, respectively. The LC-MS/MS qualitative analysis resulted in the identification of 18 components in the cob, of which N, N'-diferuloylputrescine (DFP) was selected as an active ingredient, and the quantitative analysis was conducted by variety and part. As a result, DFP was confirmed only in the cob and kernel, and it was most frequently detected in the cob of the Goldsugar of chodang corn (39.6 ㎍/g) and Daehakchal of waxy corn (38.4 ㎍/g). The cob is a by-product left over from grain removal, and is expected to create new added value as a material that promotes collagen synthesis. Through this study, we propose the possibility of using discarded cob as a wrinkle-improving functional material.
