Jaehee Jeon,Kyunghee Kim 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.12

This study developed a smartphone application (app), based on user demand, for the self-care performance of patients with chronic Hepatitis B. The smartphone app was developed in five stages. In the analysis stage, we surveyed the demand for the app among 187 patients with chronic Hepatitis B, analyzed several other apps, and conducted a literature review. In the design stage, the app’s purpose was established, and the necessary functions, system interface, database, and screens were designed. In the development stage, the app was developed. In the implementation stage, the master version of the app was used by four specialists and five participants with chronic Hepatitis B. In the evaluation stage, we conducted a heuristic evaluation and a mobile app rating scale evaluation, with these nine subjects. As a result of the evaluations, 19 aspects of the system were modified to further improve the app. This smartphone app is expected to be helpful in performing self-care, serve as a disease-related knowledge source, and promote self-efficacy in chronic Hepatitis B patients.

Objective Despite the growing need for psychological programs for North Korean refugees, most psychological interventions for these people lack a verification study that tests their effectiveness. This study aims to evaluate the effectiveness of cognitive behavioral therapy (CBT) in North Korean refugees.Methods Participants included 38 North Korean refugees, of whom 23 participated in simple relaxation and 15 participated in CBT. The Korean version of the Center for Epidemiologic Studies Depression Scale (CES-D), State-Trait Anxiety Inventory-State (STAI-S), and Impact of Event Scale-Revised were used to evaluate symptoms pre- and post-intervention.Results Participants had a significant decrease in CES-D scores after treatment (p=0.037). The decrease in CES-D was larger in those who participated in the CBT compared to those in simple relaxation (p=0.023). The superior effects that CBT had on depressive symptoms over simple relaxation were particularly more prominent in those with severe depression (p=0.035). Participants with high levels of anxiety also showed significant decreases in STAI-S scores after treatment, regardless of which type of program they participated in (p=0.023).Conclusion This preliminary findings suggests that CBT is an effective psychiatric approach in treating depressive symptoms in North Korean refugees, especially for those with a higher degree of depressive symptom.

Purpose: It is only to be expected that college students would experience various stressful situations during theCOVID-19 pandemic. The purpose of this study was to determine the effects of indoor leisure activities provided to col lege students on their stress levels and life satisfaction in the context of the COVID-19 pandemic. Methods: This studywas designed as a randomized controlled trial study. The subjects were university students aged 18 years or older, with25 in the experimental group and 30 in the control group. The experimental intervention was a 4-week indoor leisureactivity program. The research instruments used were the perceived stress scale and the Affetometer II questionnaire. Theexperimental treatment period was from April to May 2020. The data analysis methods used were frequency, percentage,mean, standard deviation, Pearson chi-square test or Fisher s exact test, and the Independent t-test. Results: The ex perimental group that participated in the indoor leisure activities had a reduced post-stress level compared to thepre-experiment group. However, there was no difference observed in the life satisfaction scores. Conclusion: In the con text of the COVID-19 pandemic, it is necessary to develop and implement various leisure activity programs to reduce thestress experienced by college students. In the future, along with a study to develop a leisure activity program to reducestress among college students, we suggest conducting a further study to evaluate its effects for a 4 weeks or more.

Purpose: The purpose of this study was to develop an instrument to assess nursing professional pride. Methods: Fifty-six preliminary items were identified through literature review and focus group interview of nurses working in a hospital. Of these, 45 preliminary instruments were completed over 0.80 of content validity index. To verify the reliability and validity of the preliminary instrument, data were collected from 294 nurses. The data were analyzed using factor analysis and multidimensional scaling analysis. Results: From the factor analysis, 27 significant items were divided into 5 subscales. These subscales were as follows: feeling of vocation, role satisfaction, role of problem solver, self-achievement, and willingness to stay. The nursing professional pride also established criterion-related validity, discriminant validity, and group validity. Cronbach’s a of the instrument was .92, and the subscales ranged from .74 to .85. Conclusion: The developed scale for nursing professional pride shows validity and reliability. The significance of this study is the development of an instrument capable of measuring nursing professional pride. To verify the relevance of this instrument, conducting comparative studies is suggested.

본 연구에서는 우레탄 변성 에폭시의 유연성 부여를 위해 propylene glycol(PPG) 기반 diamine인 Jeffamine D-400을 이용하여 폴리올을 만들고 이를 이용하여 우레탄 변성 에폭시를 합성하였다. Bisphenol A diglycidyl ether(BADGE)에 합성한 우레탄 변성 에폭시와 경화제, 경화촉진제를 배합하여 에폭시 접착제를 제조하고 접착강도 측정으로 전단 강도를 측정하였다. 측정 결과 합성한 우레탄 변성 에폭시의 우레탄 결합과 PPG사슬 도입을 통한 유연성 부여 효과로 인해 전단 강도와 전단 신율이 증가하는 경향을 보였다. 이러한 결과는 높은 가교 밀도로 인해 사용에 제약을 받고 있는 구조용 접착제에 적용이 가능할 것으로 판단된다. In this study, a polyol was prepared using Jeffamine D-400 as a propylene glycol-based diamine to impart flexibility to the urethane-modified epoxy, and a urethane-modified epoxy was synthesized using the polyol. Urethane-modified epoxy synthesized with existing Bisphenol A diglycidyl ether (BADGE) epoxy, a curing agent, and a curing accelerator are mixed to prepare an epoxy adhesive, and shear strength is measured by measuring adhesion strength. As a result, shear strength and shear elongation tended to increase. These results are due to the high crosslinking density. It is believed that it can be applied to structural adhesives that are restricted in use.

Purpose: This study was undertaken to confirm the mediating effect of ego-resilience between COVID-19 pendemic stress and depression in nursing students. Methods: This was a cross-sectional survey enrolling 125 nursing students who voluntarily participated in the study and had experienced the COVID-19 pandemic. Data were collected from May 1 to 22, 2022 through an online questionnaire comprising 74 questions. Data analysis was achieved using SPSS/Win 25.0 program by frequency and percentage, mean and standard deviation, independent t-test, one-way ANOVA, and pearson’s correlation. Mediation analysis was also conducted using Hayes’ PROCESS macro (Model 4). Result: The mean scores for depression was 2.87. The mediation effects in step 1 indicated that COVID-19 pandemic stress had a statistically significant negative effect on ego-resilience and a significant positive effect on depression. In step 2, ego-resilience imparted a statistically significant negative effect on depression. In step 3, complete mediating effects of ego-resilience were determined on the relationship between COVID-19 pandemic stress and depression. Conclusion: In order to improve the ego-resilience of nursing students, it is necessary to develop and apply an ego-resilience improvement program as a curriculum or extracurricular program in nursing colleges. Such endeavors will strategize in reducing depression among nursing students.

Rosai-Dorfman disease coexisting with ovarian tumor, mimicking metastatic ovarian cancer

Rosai-Dorfman disease (RDD) is a rare systemic histiocytic disease that infiltrates lymph nodes and extranodal sites usually in children and young adults. Typically, such patients present with fever and painless cervical lymphadenopathy. We present a case of a 68-year-old postmenopausal woman who visited the gynecology clinic with abdominal pain as her chief complaint. Imaging evaluation with abdomen-pelvis computed tomography (CT), pelvic magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT showed a huge hypermetabolic ovarian tumor with an enlarged para-aortic lymph node which was suspicious of ovarian cancer with lymph node metastasis (Figure 1). After work-up, total hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymph node dissection, and enlarged para-aortic lymph node excision were performed. Histopathologic diagnosis showed a sclerosing stromal tumor of ovary coexisting with RDD of para-aortic lymph node, of which cells from para-aortic lymph nodes were immunohistochemically positive for S-100 and CD68, common markers of RDD (Figure 2). Although complete excision was done, routine follow-up a year later revealed recurrent metastatic lymphadenopathy and lung metastasis of RDD. Although RDD is known as a non-malignant disease, disease-related complications, such as obstruction of adjacent organs or infection, can lead to a poor outcome. Likewise, this patient was eventually transferred to another institution solely for supportive care. Thus, although RDD does not occur commonly, it is important to recognize that such diseases can mimic metastatic ovarian cancer. This would help in not only the differential diagnosis of ovarian cancer, but also quickly diagnosing and treating the patient accordingly as treatment guidelines for each disease can differ greatly.
