  • As aging occurs, ow skin gets more wrinkles, becomes drier and loses its elasticity. Validating the evaluation of skin elasticity is especially important, because it is not as visible as other signs of aging such as wrinkles. Here, we identified the correlation between age and the Parameters given by Cutometer, and (we present) the parameters of that reflect the decreases in skin elasticity along with ages (Ur/Uf, Ua/Uf, Ur/Ue, Ua, $r=0.687{\sim}0.725$). Also we developed an evaluation method to quantify the difference of skin by viewing or touching. A five-grade standard of Moire topographic photo scale on face was prepared using sensory evaluation of 20 to 61 year - old women. Based on this photo standard, scoring was performed using (a) 5-grade system by three specialists to obtain the consensus score. Significant negative correlations between age and results of Cutometer $(r=-0.687{\sim}-0.725)$, Moire topography scores (r=-938) were found. Finally we have shown the significance of the correlation between the result of Cutometer and the score of Moire topography (r=0.711). Our studies using Moire topography on face have confirmed that instrumental measurements reflect the decrease in shin elasticity, which is perceived visually.

  • The purpose of this study is to investigate the effects of solving multi-strategic mathematics problems on mathematical creativity and attitudes of the 6th grade students. For this study, the researchers conducted a survey of forty nine (26 students in experimental group and 23 students in comparative group) 6th graders of S elementary school in Seoul with 19 lessons. The experimental group solved the multi-strategic mathematics problems after learning mathematics through mathematical strategies, whereas the group of comparative students were taught general mathematics problem solving. The researchers conducted pre- and post- isomorphic mathematical creativity and mathematical attitudes of students. They examined the t-test between the pre- and post- scores of sub-elements of fluency, flexibility and creativity and attitudes of the students by the i-STATistics. The researchers obtained the following conclusions. First, solving multi-strategic mathematics problems has a positive impact on mathematical creativity of the students. After learning solving the multi-strategic mathematics problems, the scores of mathematical creativity of the 6th grade elementary students were increased. Second, learning solving the multi-strategy mathematics problems impact the interest, value, will and efficacy factors in the mathematical attitudes of the students. However, no significant effect was found in the areas of desire for recognition and motivation. The researchers suggested that, by expanding the academic year and the number of people in the study, it is necessary to verify how mathematics learning through multi-strategic mathematics problem-solving affects mathematical creativity and mathematical attitudes, and to verify the effectiveness through long-term research, including qualitative research methods such as in-depth interviews and observations of students' solving problems.

  • This study investigated the impact of elementary science classes using metaverse on the academic achievement, positive experience in science, and digital literacy of elementary school students. In addition, we examined their perceptions. The respondents were derived from two classes in the sixth grade at an elementary school in Gyeonggi-do, who were selected designated as the experimental (n=29 students) and comparative (n=29) groups, respectively. Across five lessons under the "Plant Structure and Function" unit, the experimental group conducted science classes using the metaverse, whereas the comparative group conducted general textbook-based classes. To investigate instructional effects, the study performed ANCOVA using the pre-test score as a covariate, a survey on the perception of students about science classes using metaverse, and conducted interviews with a number of subjects. The result demonstrated that science classes using metaverse exerted no significant effect on scientific academic achievement and digital literacy. However, the study observed a statistically significant effect on science learning emotion which is a sub-element of positive experiences in science. The students were positively aware of science classes using metaverse in terms of interesting and diverse activities, and free expression of inquiry results and perceived the instability of smart devices and network connections as regrettable. Finally, the study posed the implications of the use of metaverse in science classes.

  • In this paper, the purpose of this qualitative research was to explore the communication experiences of nursing students during their clinical practice in the context of the COVID-19 pandemic among 4th grade nursing students. Data collection involved collecting reflective journals from 87 4th grade nursing college students who participated in clinical practice from December 19, 2022, to February 10, 2023. Participants were asked to freely write about their experiences following their clinical practice. The reflective journals were analyzed using Thematic Analysis by Braun & Clarke. In the context of the COVID-19 pandemic, the research findings have yielded 142 meaningful statements, 30 provisional themes, 9 sub-themes, and 4 central themes regarding the communication experiences of nursing college students during their clinical practice. The four central themes identified are as follows: "A mask that became a language barrier", "Broken Communication", "Fear that the quality of nursing care will decline", "Body and mind overcoming difficulties." In conclusion, this study has facilitated an understanding of the communication experiences of nursing college students during clinical practice in the context of the COVID-19 pandemic. Additionally, this research can serve as foundational information for improving ineffective communication due to the use of various medical equipment required in infectious disease situations and for developing practical strategies in nursing education under infectious disease conditions.

  • This study was carried out to provide essential data for the future health promotion projects to be aimed at improving quality of life for the elderly people in the increasingly aging society of Korea by investigating factors related to the yangseng of old people in urban areas. The results of this study are to be used as basis for efficient approach toward health promotion projects for the elderly in urban communities. For the purpose, a survey by questionnaires was conducted to urbanites from May th June 2004. The collected replies were analyzed from the viewpoints of Oriental Medicine for yangseng. 1. The average points of health care were 3.24. In details by sub-areas, 3.78 was rated for morality yangseng, 3.29 for mind, 3.30 for diet, 3.79 for activity and rest, 2.32 for exercise, 3.72 for sleeping, 2.95 for season and 1.81 for sexual life, which showed that the area of activity and rest yangseng was scored highest while the area of sexual life yangseng was rated lowest. 2. As for the extent of health care depending on the characters of subjects, higher scores were rated by men than women, younger ones than aged and spoused ones than singles. Married couples living without other family members were found to yangseng most, while more yangseng was taken by the educated, job holders and those who utilize leisure and have religion in order. 3. Men exercised more yangseng than women in the diet, exercise and sleeping. By age, the group aged 65 to 69, the more yangseng in the exercise and sexual life. The group with spouse featured higher concern for yangseng in all categories except for season. Married couples who are living with no other family members recorded the highest point in all areas except for exercise. 4. The more one is educated, the more he/she is tended to take yangseng in the sub-areas of exercise and sexual life. The group with occupation is also inclined to take more yangseng in the same sub-areas as those of the highly educated. When they pay living cost together with offspring, they appeared to be the most yangseng in season and sexual life. People who enjoy leisure showed higher yangseng in all areas except for season. Religion had a significant influence in all areas except for activity and rest yangseng. 5. Those who reply that they are confident with health and have no disease proved to have higher yangseng. Depending on whether one has disease or not, higher yangseng was confirmed in such sub-categories as mind and sleeping. Those who replied they are confident with health had higher yangseng in all areas except for season. As seen above, yangseng of the old people in the urban area is found to have different extent depending on the individual and socioeconomic characters, factors which should be seriously considered in the local health promotion projects and projects for the health of the elderly. It seems therefore necessary to launch health promotion programs and to analyze their effects to promote health care particularly in the areas of sexual life, exercise and season yangseng that featured lowest grade of yangseng in each sub-area.
