This study aims to explore how college students have adjusted to Internet-based learning (IBL) since the pandemic and how they have subjectively experienced their Internet-based classes including live-streaming and recorded classes. We conducted a qualitative study on 16 college students in South Korea. The analysis of the in-depth interviews revealed that despite early negative experiences regarding adjustment to IBL, the participants seemed to have developed an increased sense of control over their learning and simultaneously reported a greater need for self-discipline and social support in order to stay motivated. Also, instructors' digital competence and creative attempts to facilitate class communication and discussion appeared to have influence on successful IBL. Lastly, the participants' physical learning environments seemed to impact their online learning in terms of their level of alertness and motivation for study. Implications and suggestions were discussed.

This study examined the physical self-concept and self-efficacy of undergraduates. Using the convenience sampling method of non-provability sampling, a total of 377 undergraduates from North Kyongsang Province G city were selected. Of the 377 completed questionnairescollected, a total of 354 surveys with structural equation modeling were analyzed using theSPSS 22.0 statistics program. The self-esteem, endurance, health, and flexibility factors have positive effects on improvingthe self-control efficacy factor of self-efficacy in the order of physical self-concept factors. On the other hand,the higher university students perceive that among the physical self-concepts, the physical activity factor had more negative effects on the self-regulated efficacy. The self-esteem, health, and muscle strength have positive effects on improvingthe confidence factor of self-efficacy in the order of physical self-concept factors. The more perceptive endurance than the appearance, sports competence, body fat, health, self-esteem, flexibility, muscle strength of physical self-concept, and the more influence on self-efficacy. Overall, the higher the perception of physical activity factors among the physical self-concept factors, the more negative effects on the task difficult preference.

In this study, we investigated characteristics of sex-role stereotyping on 150 award-winning and traditional fairy tales (42 award-winning and 108 traditional fairy tales). The results were as follows: The depiction that female characters were rewarded for skills and competence, not for beauty, appeared more frequently in traditional fairy tales than in award-winning ones. Women were portrayed frequently as docile and passive in traditional fairy tales than in award-winning ones. Also, it was more frequently shown in award-winning tales than in traditional ones that male and female characters participated non-equally in physical activities.

Injury is a serious problem that not only causes death but also significantly degrades the quality of life of the people and causes loss of socioeconomic opportunities and costs. Damage occurs as a result of an accident. Among them, natural disasters and artificial disasters take lives of many people in a short time and threaten their physical and mental health. The United States has responded to the disaster by establishing relevant laws and regulations and a response system with the recognition that health is recognised soon to be as national security in the wake of the 9/11 terrorist attacks and the Katrina disaster. It is necessary to build a knowledge infrastructure to train disaster response experts in public health area and to have health competence to cope with disasters.

The purpose of this research was to examine the concurrent validity of the Nalongyee children's achievement motivation test by studying its relationship to a children's school readiness test. The subjects were 335 preschool children (171 urban and 164 rural) selected from 8 public and 7 private kindergartens located in two metropolitan areas (Seoul and Pusan) and 5 rural counties in Kyungsang Nam Do. Instruments included the Nalongyee Children's Achievement Motivation Test by the author and the School Readiness "Lest by Unhai Rhee. Data were analyzed by Pearson r and Z-test. Readiness was positively related to the total score and sub-areas of achievement motivation (.10-.43). Sub-areas of the achievement motivation test were related to each of the 4 factors of the readiness test. The correlations ranged from .00-.35 with the personal-social response factor, .00-.26 with the associative vocabulary factor, .05-.31 with the number concept factor, and .03-.37 with the perception factor. Significant differences in correlations were found between urban and rural areas for self-confidence, interest in learning, interest in kindergarten and physical competence.

This study of the characteristics and the relationships of children's emotional intelligence (EQ) and self-esteem had a sample of 1060 5th grade children. The rank order of four EQ factors from highest to lowest was "perception of emotion", "other-regulation and self-expression", "self-regulation and emotion utilization", and "empathy". Among self-esteem factors, "general self-worth" had the highest correlation with overall self-esteem; "physical appearance" was most strongly correlated with "general self-worth". Relationships between EQ and self-esteem showed that higher EQ was associated with higher self-esteem. Among EQ factors, "other-regulation and self-expression" was the strongest predictor of "behavioral conduct." The next strongest predictor of self-esteem among EQ factors was "self-regulation and utilization of emotion". Other self-esteem factors well predicted by EQ were "general self-worth", and "scholastic competence".

Vitrification method is widely used in oocyte cryopreservation for IVF but the birth rates are lower than that of the fresh oocyte. One of the known main reasons is structural instability of meiotic spindle and chromosome systems of mature oocyte. To get the best way for keeping competence of matured oocytes, we studied the best conditions for vitrification focused on equilibration times. The mature oocytes were underwent vitrification with current popular method and analyzed the survival rates, microtubule stability and DNA integrity. The survival rates of recovered oocyte are almost same between groups and are more than 93%. The structural configuration of meiotic spindle was well kept in 10 min equilibration group and the stability rate was almost same with that of control. The chromosomal breakdown was observed in all experimental groups, but the chromosomal stability was higher in 10 min equilibration group than the other groups. The 10 min equilibration group showed best condition compared with the other groups. Based on these results, the equilibration time is one of the key factors in successful keeping for competence of mature oocyte. Although, more fine analysis about the effects of physical stress on oocyte during vitrification is needed to define the optimal condition, it is suggested that the optimal equilibration time to get competent oocyte in mouse is 10 min. Information acquired this study may provide insight into intracellular structural events occurring in human oocytes after vitrification and application for cryopreservation of human oocyte.
