This study aimed to investigate the effects of the multimodal group intervention that combined animal-assisted therapy (AAT) and integrated play therapy (IPT) on depression and self-esteem in undergraduate university students. The subjects were 40 students attending animal-related and social welfare departments of universities located in a metropolitan city. The multimodal intervention program was conducted for eight sessions (twice a week, 60 min each) in the experimental group. Data analysis was conducted using the independent sample t-test, ANCOVA, and paired sample t-test for pre- and post-test. Therefore, the multimodal intervention program applying AAT and IPT showed positive effects on depression and self-esteem in university students. Based on these results, this study proposed the operation of multidisciplinary education and practical and policy utilization methods to reduce depression among university students and help improve their self-esteem.

본 연구는 체감형 댄스게임이 여성노인의 정적 및 동적 균형에 미치는 영향을 조사하는 데 목적이 있다. 연구 참가자들은 무작위 배정하여 체감형 댄스 게임 실험집단(n=10)과 통제집단(n=10)으로 나눈 후 실험집단은 일주일에 세번, 60분씩 6주간의 기간 동안 참여했고 통제집단은 일상생활 외 운동을 진행하지 않았다. 댄스게임의 균형 능력을 평가하기 위해 버그 균형검사(BBS), 기능적 팔 뻗기 검사(FRT), 일어나 걸어가기 검사(TUG)를 사용하여 평가하였다. 데이터는 통계적 유의성을 결정하기 위해 대응표본 t검정(paired t-test)과 독립표본 t검정을 사용하여 분석했다. 체감형 댄스 게임 그룹의 BBS, FRT, TUG 연구 결과, 통계적으로 유의한 차이를 보였다(p<.05). 결론적으로, 체감형 댄스 게임은 여성노인들의 균형 능력 향상에 효과가 있는 것으로 나타났다. 여성노인들에게 체감형 댄스게임 "댄스센트럴" 프로그램을 규칙적으로 지속한다면 균형성 향상에 도움이 될 것으로 생각된다. 후속적으로 노인에게 적합한 댄스게임 개발에 대한 연구가 이루어져야 할 것으로 생각된다.

Background The umbilicus makes an important contribution to the natural appearance of the abdomen. To date, studies on its position in Korean women are lacking, and no standards have been established. The purpose of this study was to investigate the position of umbilicus in Korean women and to review changes in its position after ipsilateral pedicled rectus abdominis musculocutaneous (IP-RAM) flap. Methods This research consisted of two studies. In first study, 100 females who visited the emergency department with gastroenteritis between 2007 and 2011 were included. In second study, 40 women who underwent IP-RAM flap in the same period were included. Using abdominal computed tomography, we measured the distance between xiphoid process and umbilicus, represented by value a, and the distance between umbilicus and symphysis pubis, represented by value b. Thus, the location of the umbilicus was represented by the ratio a/b. The data were analyzed using Pearson correlation test and paired t-test. Results In study 1, the mean value of a/b was 1.07. Pearson correlation test revealed a significant correlation between age and a/b. In study 2, the mean value of a/b was 1.16 in preoperative measurements and 1.01 in postoperative measurements. The paired t-test showed a significant difference between preoperative and postoperative measurements, indicating cephalic migration of the umbilicus after surgery. Conclusions The natural position of the umbilicus showed caudal migration with aging. Additionally, in a comparison of preoperative and postoperative measurements in patients who underwent IP-RAM flap, cephalic migration of the umbilicus was observed after surgery.

Objectives: This study aimed to analyze the effects of smart-learning on the education of dental hygiene students. Methods: This study was conducted on 135 students in the dental hygiene department from a single university, with a pre-test implemented in order to verify the homogeneity of the experimental (smart-learning exposed) and control groups. Following each group's lecture, we measured the study achievements of the students via a post-test, and their learning satisfaction through a questionnaire. An independent t-test was conducted to examine the homogeneity of the two groups and to compare both study achievements and learning satisfaction. Furthermore, a paired t-test was performed in order to compare the study achievements before and after lectures. Results: The average learning satisfaction level of the experimental group was $4.65{\pm}0.43$, which was higher than that of the control group ($4.46{\pm}0.54$) (p<0.05). After comparing the study achievements of the groups, there was no statistically significant difference between them, both before and after lectures. Paired comparisons conducted on the overall study achievements showed that they significantly increased following lectures when compared to what they were beforehand, in both the smart-learning and control groups (p<0.001). Conclusions: Smart-learning can be expected to result in positive effects for dental hygiene education, and further structural studies on the various types of smart-learning are needed.

Purpose: The purpose of this study was to investigate the effect of aromatherapy on pain, depression, and feelings of satisfaction in life of arthritis patients. Method: This study used a quasi-experimental design with a non-equivalent control group, pre-and post-test. The sample consisted of 40 patients, enrolled in the Rheumatics Center, Kangnam St. Mary's Hospital, South Korea. The essential oils used were lavender, marjoram, eucalyptus, rosemary, and peppermint blended in proportions of 2:1:2:1:1. They were mixed with a carrier oil composed of almond (45%), apricot(45%), and jojoba oil(10%) and they were diluted to 1.5% after blending. The data were analyzed using an 2-test, Fisher's exact test, t-test and paired t-test. Result: Aromatherapy significantly decreased both the pain score and the depression score of the experimental group compared with the control group. However, aromatherapy didn't increase the feeling of satisfaction in life of the experimental group compared with the control group. Conclusion: The result of this study clearly shows that aromatherapy has major effects on decreasing pain and depression levels. Based on our experiment's findings, we suggest that aromatherapy can be a useful nursing intervention for arthritis patients.

Purpose: In this study a caregiver's role improvement program was developed and tested to identify the effect on uncertainty, stress, and role performance of caregivers with hospitalized children. Methods: The design of this study was a quasi-experimental study with a nonequivalent control group and a non-synchronized design. Thirty-three caregivers were assigned to the experimental group and 33 to the control group. Data were collected from March 5 2016 to April 10 2016. For the experimental treatment, each individual was given on-site education with situated learning (given 30 minutes each, for 2 sessions), and self-repetition learning activities were performed from the e-book. Data were analyzed using t-test, ${\chi}^2-test$, Fisher's exact test, paired t-test, and independent t-test. Results: The level of uncertainty and stress decreased, and role performance level improved for these caregivers with hospitalized children. Conclusion: The findings of this study show that using on-site education through situated learning and self-repetition learning with an e-book as in the caregiver's role improvement program is an effective intervention. Therefore, utilizing the caregiver role improvement program developed in this study is recommended as an effective intervention for caregivers of hospitalized children.

Retention of CPR knowledge was assessed in a group of 86 police officers who participated in first aid and emergency rescue program on February, 2001 and 3 months later. Police officers were taken written test about CPR knowledge by American Heart Association Guidelines 2000 and competence level. Data were analyzed by Frequency, Percentage, Mean, paired t-test using SPSS program. The results for this study were as follows ; 1. In the post-test, the highest question was a rechecking time of circulation sign(98.8%), the lowest was a check for signs of circulation(17.4%), in 3months later, the highest question was a chest compression(94.2%), the lowest was a check for signs of circulation(1.2%), and a retention of CPR knowledge was a 71.7%. In 3months later, knowledge level was decreased compared to that of post-test(t=-9.09, p=.000). 2. In 3months later, the competence level was decreased compared to that of post-test(t=3.09, p=.003).
