Purpose: This survey was to investigate the differences in smartphone addiction symptoms by the level of addiction among college students in S. Korea. Methods: Two hundred and thirteen university students survey data was collected from December 5th to 9th of 2011 using Smartphone Addiction Scale. 25.3% (n=54) of total respondents were categorized as highly addicted and 28.17% (n=60) were as non-addicted group. Results: There were significant differences in total addiction symptom scores, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. There were significantly differences in total addiction symptoms, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. Highly addicted group were significantly higher in total addiction symptom scores (3.26 times), daily life disorders (4.96 times), loss of self control (3.07 times), pathological concentration (3.07 times), and compulsive symptoms (2.86 times) compared to non-addicted one. Highly addicted group had significantly higher daily usages of smartphone and were more satisfied with smartphone than non-addicted group. The purpose to use was related to academic works rather than games or entertainment. However satisfaction on academic achievement was very low. Conclusion: The smartphone addicted symptoms related to academic works were significantly high in highly addicted college students so that it disturbed their daily life and psycho-social health in general. It is clear that the highly addicted college students need urgent distinctive interventions such as creative academic guides.

Objectives : The purpose of this study was to examine the educational effects of team learning by having learners keep a journal to record, check and reflect on their own learning. It's basically meant to investigate the effects of team learning on learning motivation and academic achievements to provide some information on teaching-learning strategy setting tailored to learner characteristics. Methods : The subjects in this study were 49 college sophomores. After they were divided into an experimental group and a control group, the experimental group of 24 students engaged in team learning from March to June, 2012, and that group was asked to keep a reflective journal every week to determine whether writing a reflective journal in every session served to boost their learning motivation and academic achievement or not. Results : 1. After the experimental group kept a reflective journal, that group underwent a significant change in learning motivation from a mean of 3.34 in the pretest to a mean of 4.01 in the posttest(p<0.05). The experimental group showed a more positive improvement than the control group. 2. After the experimental group kept a reflective journal, they underwent a significant change in academic achievement from 22.7 in the pretest to 23.5 in the posttest(p<0.05). The control group showed no significant improvement in academic achievement. Conclusions : The findings of the study illustrated that keeping a reflective journal had a positive impact on the learning motivation of the learners, and the findings of the study are expected to lay the foundation for future research in new teaching methods for the department of dental hygiene.

Purpose: The purpose of this study was to investigate the effects of simulation in nursing education based on caring for elderly cognition disorder patients. The education consisted of a caring program for patients that included a process of assessment of a patient's mental status, diagnosis of the patient's health condition, and intervention to address the problems by using therapeutic communication. Methods: A nonequivalent control group pretest-posttest design was used. A total of 69 subjects (undergraduate students) participated in the education and they were assigned to two groups: the experimental group (n=32) and the control group (n=37). Data-gathering structured questionnaires that included communication competence, academic self-efficacy, and attitudes about the elderly. The data were collected from October 2013 to December 2013, and statistical analyses were conducted with-test and t-test using the SPSS 21.0 program. Results: With respect to education, there was significant improvement in communication competence in the experiment group (t=2.41, p=.022) compared with in the control group (t=.69, p=.494). However, there was no statistically significant difference in academic self-efficacy and attitude about the elderly. Conclusion: Simulation-based education should continue to be developed further for better elderly-patient care. Integrated education in particular using a high-fidelity simulator will contribute to improvements in nursing competence in this area.

In cancer patients, chemo/radio therapy may cause infertility by damaging the spermatogenesis affecting the self-renewal and differentiation of spermatogonial stem cells (SSCs). In vitro differentiation of stem cells especially mesenchymal stem cells (MSCs) into germ cells has recently been proposed as a new strategy for infertility treatment. The aim of this study was to evaluate the proliferation and differentiation of SSCs using their co-culture with Sertoli cells and conditioned medium (CM) from adipose tissue-derived MSCs (AD-MSCs). Testicular tissues were separated from 2-7 days old neonate Wistar Rats and after mechanical and enzymatic digestion, the SSCs and Sertoli cells were isolated and cultured in Dulbecco's modified eagle medium with 10% fetal bovine serum, 1X antibiotic, basic fibroblast growth factor, and glial cell line-derived neurotrophic factor. The cells were treated with the CM from AD-MSCs for 12 days and then the expression level of differentiation-related genes were measured. Also, the expression level of two major spermatogenic markers of DAZL and DDX4 was calculated. Scp3, Dazl, and Prm1 were significantly increased after treatment compared to the control group, whereas no significant difference was observed in Stra8 expression. The immunocytochemistry images showed that DAZL and DDX4 were positive in experimental group comparing with control. Also, western blotting revealed that both DAZL and DDX4 had higher expression in the treated group than the control group, however, no significant difference was observed. In this study, we concluded that the CM obtained from AD-MSCs can be considered as a suitable biological material to induce the differentiation in SSCs.
