An animation film, , is a work that declared a perfect revival of Disney. It is considered that the success was the result of its impressive theme song and characters working influentially. The main characters let audience experience empathy as well as catharsis by building the image of women making their own future without relying on men, and among the characters, Elsa is still popular even if one year has passed since its premiere in Korea. In the narrative genre, the character's degree of completion is regarded to be so important that it can even determine the work's success or failure. Accordingly, to analyze the personality structure among the major components of character rising, this study focuses on the psychodynamics of fear and desire which determines the directions of thought or behavior. Fear is the emotion attributed not to a real threat but to an ominous assumption about the future. Because fear that is originated from the memory of any deficit or suppression distorts our sound needs, escaping from fear means facing the reality. To verify the unique psychodynamics of the characters, the researcher analyzed the hierarchy of their attitudes, psychological dispositions, and psychic functions by using 'MBTI Personality Typology'. According to the results, (1) Elsa and Anna are in a conflicting relationship in terms of psychic functions. Although they are the combination that shows the highest possibility of conflict, the two sisters overcome it basically grounded on fellowship and family love. (2) Although Hans and Kristoff, too, are against each other in terms of psychic functions, the two male characters do not interact with each other in the work. (3) Hans is a person equipped with psychic functions that can complement both Elsa and Anna the most effectively, but he abuses it and turns into the most fatal opponent to them. (4) Olaf is a type of person combining Anna's attitudes with Elsa's psychological dispositions. And according to the results of analyzing the frequency of expressing fear and desire, (1) Elsa employs overwhelming fear and Anna and others characters use desire as the major drive of their behavior. (2) Fear is the underlying deficit internalized in every character and is attributed to 'the deficit of family love', and as a result, they all share the pain of 'loneliness and isolation'. It is thought that analyzing psychodynamics will help us understand the character's growth tale, that is, the narration that they distort their desire for the first motive to avoid fear and end up being ruled by it, and also, they realize the underlying reason for the distorted desire in the process of getting rid of their own fear and reach self-healing. Lastly, regarding character rising in the animation, it is expected that the directions and analysis results of this research will be referred to as a database in creating characters and setting up relations among them.

The findings of the study illustrated that the college students felt more stress when they had to receive treatment for the sake of oral health, and that they experienced less stress when they took good care of their oral health for preventive purposes. A self-administered survey was conducted on 235 junior college students whose majors were unrelated to health in the region of Jeollanam-do from March 4 to 30, 2015. A total of 27.2% of the respondents had received dental caries treatment, and 48.1% had received periodontal treatment. When the stress of the college students about personality, appearance, families and interpersonal relationship was measured, they were most stressed out about their personality ($3.40{\pm}0.73$). Specifically, they scored highest in the item "It's such a hassle to do something" ($3.73{\pm}1.20$), and scored lowest in the item "I was concerned about someone else's problem" ($2.22{\pm}1.15$). The female students experienced more stress about their appearance, personality, families and interpersonal relationship than the male students. The male students felt more stress about their studies than the female students. The college students who had dental caries and periodontal diseases suffered stress that was above the average level, and the stress level of the group that had scaling experience and/or had received toothbrushing education, namely taking care of oral health for preventive purposes, was more below average than the other group that didn't. In a word, it's urgently required to take measures to prevent college students from having oral diseases, as the students who suffered from oral diseases and received treatment were more stressed out. The implementation and revitalization of systemized educational programs are required to help college students stay away from oral diseases to promote their oral health.

Objective: Human embryonic stem cells (hESCs) have the capacity to differentiate into all of the cell types and therefore hold promise for cell therapeutic applications. In order to utilize this important potential of hESCs, enhancement of currently used technologies for handling and manipulating the cells is required. The cryopreservation of hESC colonies was successfully performed using the vitrification and slow freezing-rapid thawing method. However, most of the hESC colonies were showed extremely spontaneous differentiation after freezing and thawing. In this study, we were performed to rapidly collect of early passage hESCs, which was thawed and had high rate of spontaneously differentiation of SNUhES11 cell line. Methods: Four days after plating, partially spontaneously differentiated parts of hESC colony were cut off using finely drawn-out dissecting pipette, which is mechanical separation method. Results: After separating of spontaneously differentiated cells, we observed that removed parts were recovered by undifferentiated cells. Furthermore, mechanical separation method was more efficient for hESCs expansion after thawing when we repeated this method. The recovery rate after removing differentiated parts of hESC colonies were 55.0%, 74.5%, and 71.1% when we have applied this method to three passages. Conclusion: Mechanical separation method is highly effective for rapidly collecting and large volumes of undifferentiated cells after thawing of cryopreserved early passage hESCs.

This study was conducted to investigate the effects of two dry matter levels of liquid swine manure on dry matter yield and nutritive value of Italian ryegrass, rye and oats, and the chemical characteristics of soil in Jeju. This experiment tested in split plot design. Three forage crops (Italian ryegrass, rye and oats) were the main plot and four fertilizers (no fertilizer=T0, chemical fertilizer=T1, liquid swine manure with DM 2.7%=T2 and liquid swine manure with DM 5.9 %=T3) were the sub plots. Yield and nutrient contents of forage crops and soil properties were determined. Application of liquid swine manure containing 5.9% dry matter resulted in highest DM yield in all three forage crops species compared with the other treatments (p<0.01). Crude protein content(%) and crude protein yield(kg/ha) of forage crops were highest in rye compared with the other forage crops species(p<0.01). K and Mg contents of soil were higher(p<0.01) in rye than in the other species while Na contents was higher(p<0.01) in Italian ryegrass than others. Mg content of soil appeared higher in rye than in the others and higher(p<0.05) in forage crops applied with liquid manure containing 2.7% DM compared with the other species. $NO_3-N$ contents in soil was lower in rye than the other species and higher in species with chemical fertilizer. These findings indicate that most of liquid swine manure produced on local pig farms containing low levels of dry matter and other nutrients suggest a low efficiency of its use as a fertilizer. The liquid swine manure is recommended as a fertilizer for rye production in winter, compared with Italian ryegrass or oat.

Studies were carried out to evaluate the effect of liquid pig manure on the production of Japanese millet, the chemical characteristics of pasture soil and leaching water. The study was undertaken from June to September 2005. Randomized complete block design was used to allot four treatments: T1 (no fertilizer), T2 (N : 200 kg/ha, p : 150 kg/ha, K : 150 kg/ha), T3 (liquid pig manure containing 1.7% DM 200 kg N/ha) and T4 (liquid pig manure containing 7.0% DM 200 kg N/ha). Leaching water was sampled at 21 August (1st time), 9 September (2nd time) and 26 September (3rd time), 2005, respectively. No significant differences in the dry matter yield of Japanese millet was found among the four treatments, whereas the plant lengths of Japanese millet were higher in the T2, T3 and T4 than in T1 (p<0.05). Nitrogen, P and K uptake of J. millet tended to be influenced by application of chemical fertilizer or 7.0% DM liquid pig manure compared with T1 or 1.8% DM liquid pig manure. The organic matter (OM) content of soil was higher in T2, T3 and T4 than in T1. Na content was highest in T3 among the four treatments. $NO_{3^-}N\;or\;NH_{4^-}N$ content in leaching was not different among the four treatments. $SO_4$ content in leaching water sampled in 1st time was high in T4, but in T3 from 3rd time (p<0.05). Cl, Mg and Na contents were high in leaching water sampled in the 1st time from T4, whereas high in those from T3 in 2nd or 3rd time. Results show that the application of a high DM liquid pig manure is not better for producing Japanese millet and improving the properties of pasture soil than a low DM liquid pig manure. However, the contents of $SO_4$, Cl, Mg and Na in leaching water sampled in 1st time were high in a high DM liquid pig manure.

This study was carried to investigate the nutrition knowledge, dietary habits and nutrition attitude of 227 teachers of elementary and middle school in Masan city. The survey was conducted by a self-administered questionnaire. The results showed that the subjects had a high level of perceived nutrition knowledge (85.2%), but the accuracy of the knowledge was 76.2%, and percentage of correct answers was 65.5%. The average nutrition knowledge score was 13.1 out of possible 20 points, the average score of dietary habits was 76.2 and nutrition attitudes score was 70.8 out of 100 points. Most of the subjects are belonged to the 'good'group in terms of nutrition knowledge, dietary habits and nutrition attitudes level. Female teachers scored significantly higher on nutrition knowledge and nutrition attitudes than male teachers did (p<0.001). And elementary school teachers scored significantly higher on dietary habits than noddle school teachers (p<0.01). There was a highly significant correlations between nutrition knowledge and nutrition attitude (r =0.3, p<0.001); dietary habit and nutrition attitude (r : 0.4, p<0.001). But the correlation between nutrition knowledge and dietary habits was not significant.

The purpose of this study was to investigate the regional differences in anthropometric measurement, dietary behavior and nutrient intake among the nation-wide college students participating in a nutritional education program via internet. The subjects were 1614 college students (male: 752, female: 862) and divided into 4 regional groups. A cross-sectional survey was conducted using a self administered questionnaire, and the data were collected via internet or by mail. The nutrient intake data collected from food record were analyzed by the Computer Aided Nutritional Analysis Program. Data were analyzed by SPSS 10.0 program. Average age of male and female college students were 23.6 years and 21.0 years, respectively. Most of the male and female college students had poor eating habits, such as unbalanced meals and skipping meals. In particular, more than 60% of the male college students in Chungcheong and Gyeongsang areas had irregularity of meal time. Female students in Seoul and Incheon areas showed significantly higher consumption frequency of yellow and green leafy vegetables compared to Chungcheong and Gyeongsang areas. Female students in Seoul, Incheon and Chungcheong areas showed significantly higher consumption frequency of milk and milk products compared to Gyeongsang area. Calorie, vitamin A, calcium and iron intakes of the male students and calorie, vitamin A, vitamin $B_2$, niacin and calcium intakes of female students were lower than the Korean RDA. Female students in Incheon area showed significantly higher vitamin C and iron intakes compared to the other areas. These results provide a nation-wide information on dietary behavior and nutrient intake among Korean college students.

Educational communities around the world have concentrated on integrative efforts among science, technology, engineering and mathematics (Science, Technology, Engineering, and Mathematics: STEM) subjects. Korea has focused on integrative education among STEAM (Science, Technology, Engineering, Arts, and Mathematics) school subjects to raise talented human resources in the fields of science and technology. The purpose of this study was to analyze secondary school science, technology, and mathematics teacher's perceptions and needs toward integrated education and integrative STEM education. A total of 251 secondary school teachers from all areas of the country who have taught science, mathematics, and technology were surveyed by using a self-reported instrument. The findings were as follows: First, teachers have used little integrated education in their classes due to insufficient time in the actual preparation of the integrated education and the lack of expertise, teaching experience, and teaching-learning materials for the integrated education, while they have positive thoughts about the need of integrated education. Second, they presented several needs to facilitate the integrated education: development of a variety of integrated programs, school administrative and financial support, and in-service teachers' training. Third, overall perception toward integrated STEM education was not sufficient, but most teachers perceived the need toward integrated STEM education due to students' development in their creativity, thinking skills, and adaptability. Fourth, they perceived that it was imperative to develop the various integrated STEM education programs, distribute the materials, and help STEM teachers' understanding toward integrated STEM education. Fifth, they perceived that the most relevant method to integrate STEM subjects was the problem solving approach. In addition, they appreciate that the integrated STEM education is highly efficient in not only developing integrated problem solving skills and STEM related literacy, but also in positively impacting the rise of talented human resources in the fields of science and technology. In order to increase the awareness of STEM-related secondary school teachers and vitalize the integrated STEM education, it is necessary to develop and spread a variety of programs, effective teaching and learning materials, and teachers' training programs.
