The aims of this study were to identify the correlations among the knowledge about suicide, preparation to perform activities and self-evaluation of suicide prevention. Methods : The data were collected using self-reported questionnaires comprised of the three measurements and demographic characteristics from 332 army officers in Republic of Korea on April and May in 2013. The data were analyzed with SPSS/WIN 18.0 in terms of frequency, percentage and average, t-test, ANOVA and Pearson`s correlation coefficient. Results : The mean of knowledge score about suicide is 57.5. The mean of preparation to perform activities of suicide prevention is 40.6 out of 56. The mean of self-evaluation of suicide prevention is 43.5 out of 63. Knowledge score about suicide to characteristic was a significant distance depends on experience of commander and experience to learn about suicide prevention. The correlation among the knowledge score about suicide, preparation to perform activities and self-evaluation of suicide prevention showed a positive correlation. Conclusion : It is needed activities about suicide prevention to reduce the suicide rate led by a commander. In case of absence of counselors for suicide prevention, it would be possible to assign who experienced in commander and educated about suicide prevention.

황나래,권민영,차재봉,정수월,우제문 대한안과학회 2016 Korean Journal of Ophthalmology Vol.30 No.6

Purpose: To investigate the production of long pentraxin 3 (PTX3) in response to tunicamycin-induced endoplasmicreticulum (ER) stress and its role in ER stress-associated cell death, PTX3 expression was evaluatedin the human retinal pigment epithelial cell line, ARPE-19. Methods: PTX3 production in ARPE-19 cells was analyzed in the absence or presence of tunicamycin treatmentby enzyme-linked immunosorbent assay. PTX3 protein and mRNA levels were estimated using western blotanalysis and real-time reverse transcription-polymerase chain reaction, respectively. Protein and mRNA levelsof CCAAT-enhancer-binding protein homologous protein (CHOP) and ARPE-19 cell viability were measuredin the presence of tunicamycin-induced ER stress in control or PTX3 small hairpin RNA (shRNA)-transfectedARPE-19 cells. Results: The protein and mRNA levels of PTX3 were found to be significantly increased by tunicamycin treatment. PTX3 production was significantly decreased in inositol-requiring enzyme 1α shRNA-transfected ARPE-19 cells compared to control shRNA-transfected cells. Furthermore, pretreatment with the NF-kB inhibitorabolished tunicamycin-induced PTX3 production. Decreased cell viability and prolonged protein and mRNAexpression of CHOP were observed under tunicamycin-induced ER stress in PTX3 shRNA transfected ARPE-19 cells. Conclusions: These results suggest that PTX3 production increased in the presence of tunicamycin-inducedER stress. Therefore, PTX3 could be an important protector of ER stress-induced cell death in human retinalpigment epithelial cells. Inositol-requiring enzyme 1α and the NF-kB signaling pathway may serve as potentialtargets for regulation of PTX3 expression in the retina. Therefore, their role in PTX3 expression needs to befurther investigated.

This study aims to verify the structural relationship between sports-related social media users' satisfaction, and brand attitudes, information attitudes and to find out the intention of social media users to participate in sports in the future. The study participants were sports-related social media users in their 20s and 40s, and a total of 521 survey papers were used to analyze the data. The data was processed using SPSS and AMOS programs and the following results were obtained. Satisfaction has been shown to have a significant impact on brand attitude, information attitude, and willingness to participate in future sports. In addition, the information attitude had a significant impact on future sports participation, but the brand attitude did not have a significant impact. In conclusion, in order to lead to practical participation in future sports through this research, social media companies and content creators need to focus on bringing up fresh ideas based on accurate information to guide users' satisfaction. In future studies, a multidimensional empirical study of information attitudes needs to provide a more specific understanding of the relationship between each variable. 본 연구는 스포츠관련 소셜미디어 이용자의 만족과 브랜드태도, 정보태도간의 구조적 관계를 검증과 향후 소셜미디어 이용자들의 직접적인 스포츠참여 의도를 알아보는데 그 목적이 있다. 연구 대상자들은 20~40대의 스포츠관련 소셜미디어 이용자로 총 521개의 설문지가 자료 분석에 사용되었다. SPSS와 AMOS프로그램을 이용하여 자료처리 하였으며 다음과 같은 결과를 도출했다. 만족은 브랜드태도와 정보태도 그리고 미래스포츠 참여의도에 유의미한 영향을 미치는 것으로 나타났다. 또한 정보태도는 미래스포츠 참여의도에 유의미한 영향을 미쳤지만 브랜드태도는 유의미한 영향을 미치지 않는 것으로 나타났다. 결론적으로 이 연구를 통하여 실질적인 미래스포츠 참여를 이끌기 위해 소셜미디어 기업과 컨텐츠 제작자들은 정확한 정보를 토대로 참신한 아이디어를 내세워 이용자들의 만족을 이끌기 위해 집중해야 하는 필요성을 제시하고 있다. 향후 연구에서는 정보태도와 관련하여 다차원으로 구성된 실증연구를 통해서 각 변인간의 관계를 보다 구체적으로 파악할 필요가 있다.

This study investigated the change in heart rate during exercise and the recovery phase after horseriding exercise. Additionally, it provides basic data for exercise prescriptions by analyzing the difference between professional and amateur horse riders. The subjects of this study included 21 participants (11 professional and 10 amateur horse riders). The heart rate was measured 11 times for 1-minute durations at rest 1, 2, 3, 4, and 5 minutes of horse-riding, and 1, 2, 3, 4, and 5 minutes of recovery phase. In statistical analysis, repeated measure analysis of variance and independent t-test were conducted. The level of significance was set at 0.05. Both professional and amateur horse riders, in time effect, showed a significant increase in heart rate for 5 minutes of horse-riding every minute, and showed a significant decrease during the recovery phase (F=29.923, p<.001). However, there was no significant group effect difference of the overall pattern of change between professional and amateur horse riders (F=1.006, p=.497). Nevertheless, there was a significant difference between professional and amateur horse riders in interaction effect (time x group) (F=8.204, p=.009). The result of the post-hoc test is as follows. There was no significant difference in resting heart rate before horse-riding between professional and amateur horse riders (t=.458, p=.652). However, amateur horse riders showed a statistically higher heart rate compared with professional riders from 5 minutes of the exercise phase to 1 minute of recovery phase (p<.05). There was no significant difference in heart rate between professional and amateur horse riders from 2 minutes of recovery phase to the 5 minutes of recovery phase (termination of experiment) (p>.05). In conclusion, it is assumed that the change of heart rate results from the psychological tension rather than from the exercise itself, leading to rapid decrease of heart rate within 5 minutes after finishing horse-riding, as the effect of psychological tension is removed. We hope that more systematic studies about the intensity of horse-riding exercise are followed.

Large Unstained Cell, Blast Suspect and Delta Neutrophil Index ll Analyzed with Automated Hematology Analyzer as Parameters for the Prediction of Acute Leukemia Relapse

황나래,김유경,서장수 대한진단검사의학회 2019 Laboratory Medicine Online Vol.9 No.3

Background: Here we investigated the clinical utilities of blast suspect, large unstained cell (LUC), delta neutrophil index ll (DN ll), and delta neutrophil index l (DN l), analyzed in peripheral blood samples with automated hematology analyzers to predict the relapse of acute leukemia. Methods: We retrospectively reviewed the medical records of 112 patients, including 56 patients with acute leukemia relapse and 56 controls. Blast suspect, LUC, DN ll, and DN l were compared between the control and leukemia relapse groups. Results: Significant differences in blast suspect (P<0.001), LUC (P<0.001), DN ll (P<0.001), and DN l (P=0.002) were observed between the leukemia relapse and control groups. The areas under the curve (AUC) value was 0.927 for blast suspect (95% confidence interval [CI]: 0.8750.978, P<0.001), 0.868 for LUC (95% CI: 0.794–0.941, P<0.001), and 0.900 for DN ll (95% CI: 0.841–0.960, P<0.001). Logistic regression analysis for the prediction of leukemia relapse revealed odds ratio values of 1.52 (95% CI: 1.26–1.96, P=0.0002) for blast suspect, 1.66 (95% CI: 1.27–2.42, P=0.0019) for LUC, 1.16 (95% CI: 1.08–1.29, P=0.0014) for DN ll, and 1.05 (95% CI: 1.01–1.13, P=0.0845) for DN l. Conclusions: Multiple parameters provided by automated blood cell analyzers may serve as powerful ancillary tools for the prediction and diagnosis of leukemia relapse.
