Purpose: The objective of this systematic review was to assess the effects of family support programs on caregiving burden, depression, and stress in family caregivers of people with dementia. Methods: A literature search was conducted of electronic databases to identify randomized controlled studies with family support programs done between 2000 and 2014. Studies published in English and/or Korean were included for the analysis with search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group. Studies were rated for quality assessment by two independent reviewers using the appraisal checklist developed by Cochrane Reviews and Dissemination. Of 8,334 articles identified in the literature search, full texts of 76 articles that met the inclusion criteria were reviewed and 38 were found to include relevant outcomes. Results: Results from selected studies were pooled in statistical meta-analysis using Review Manager Software and heterogeneity between combined studies was assessed using the Chisquare test. Meta-analysis showed that the effect sizes of family caregiver support programs were small to medium for categories of caregiving burden (Hedge’s g= - 0.17, 95% CI= - 0.30~ - 0.04), depression (Hedge’s g= - 0.30, 95% CI= - 0.40~ - 0.20), and stress (Hedge’s g= - 0.39, 95% CI= - 0.52~ - 0.25). Conclusion: The review results indicate that a support programs can assist family caregivers in reducing their psycho-emotional distress.

Purpose: This study aimed to investigate patterns of health risk behavior in older adults with chronic joint pain.Methods: This study utilized the 5th and 6th Korea National Health and Nutrition Survey Data (KNHANES V, VI).In total, 6,534 older adults over the age of 64 were surveyed between 2010 and 2013. The secondary analysisincluded 5,909 respondents who answered yes to knee, hip, and back pain and had chronic joint pain for morethan 30 days in the last 3 months. Results: According to the behavioral analysis of smoking, excessive drinking,physical inactivity, inappropriate weight, inappropriate sleep time, breakfast skipping, and frequent dining out ashealth risk behaviors, older adults with chronic joint pain were physically inactive and experienced inadequatesleep, with 84.2% of men and 98.6% of women engaging in more than two health risk behaviors. Health riskbehaviors occurred together with proven correlations. The association analysis showed that clusters of healthrisk behaviors were more frequent in men and that inadequate sleep, inadequate weight, and physical inactivitystrongly correlated. Conclusion: The study findings provide information regarding health risk behaviors thatinterventions should focus on to promote better health for older adults with chronic joint pain. Intervention researchis also needed to test health promotion programs that aim to prevent such health risk behaviors in older adultswith chronic joint pain.

Purpose: The purpose of this study was to examine the effect of laughter therapy on depression, anxiety, fatigue, and quality of sleep in gastrointestinal cancer survivors. Methods: This study was a randomized controlled trial. We compared the effect of laughter therapy with usual care only in post chemotherapy gastrointestinal patients. Outcomes included changes in depression and anxiety (according to the Hospital Anxiety and Depression Scale), fatigue (according to the Fatigue Severity Scale), and quality of sleep (according to the Verran & Synder-Halpern Sleep Scale). Data was collected July 2015 through January 2016. Seventy nine participants who agreed to participate in this study were randomized to either the experimental group (n=40) or the control group (n=39). Therapy included eight sessions (60 minutes each, once weekly). Data were analyzed using the Windows SPSS 22.0 program. Results: Laughter therapy was effective in reducing fatigue (p=.019) and increasing satisfaction of sleep (p=.030). There were no differences between the groups after therapy for depression (p=.129) and anxiety (p=.200). Conclusion: Results of this study indicate that laughter therapy may be an effective nursing intervention for improving the health status of gastrointestinal cancer survivors after chemotherapy.

Solid pseudopapillary pancreatic neoplasms are rare. The male-to-female ratio is 1:9, and metastasis occurs only in a few cases. A 39-year-old male with a solid pseudopapillary neoplasm (SPN) with lymph node metastasis underwent ultrasonography, CT, and MRI, which revealed a mass (8 cm) in the pancreatic head. Fluorodeoxyglucose (FDG)-PET showed a hypermetabolic lymph node in the root area of the superior mesenteric artery (SMA). The patient underwent pylorus-preserving pancreaticoduodenectomy, which confirmed a peripancreatic lymph node metastasis. The lymph node of the SMA root area remained because of the encasing of the superior mesenteric artery. After 14 months of follow-up (with no adjuvant therapy initiated), the residual metastatic lymph nodes showed no change and no recurrence. In conclusion, surgery of the primary tumor for patients with SPN is recommended, even in cases with metastatic lymph nodes remaining. (Korean J Gastroenterol 2022;79:77-82)

Scrambling in Korean Parasitic Gap Constructions and its Cross-linguistic Implications

Seyeon Park(박세연) 한국언어학회 2018 언어 Vol.43 No.1

Parasitic gap constructions have been observed to fall into two subtypes across languages: adjunct clause type and subject clause type. Previous research on Korean parasitic gaps has either assumed that both subtypes exist in Korean as in English, or analyzed the movement properties of scrambling as in Japanese. This paper is about the argument that the previous studies have not considered the specific properties of the clausal boundaries and scrambling patterns in Korean. In this paper, the distinct properties of adjunct clauses and subject clauses in Korean were examined to see how their differences structurally affect the pattern of scrambling. I propose that the subject clause type of the parasitic gap construction exists in Korean, but what has been analyzed as the adjunct clause in the literature should be analyzed as containing a null pronoun. This claim is empirically supported by comparing the properties of a parasitic gap with those of a null pronoun. On the basis of the observed pattern in Korean parasitic gap constructions, I discuss its cross-linguistic implications on the parasitic gap hierarchy proposed by Culicover (2017).

본 연구에서는 개복숭아꽃과 흰색, 분홍색 매화 꽃의 항균 활성과 항산화, 미백 효과에 대해 알아보고자 하였다. 먼저, 3종의 꽃추출물들은 4종의 균주 중에 S. aureus에 대해 우수한 항균 활성을 나타냈다. 흰매화 클로로포름층은 0.5 mg/mL 농도에서 S. aureus에 대해 84%의 항균 활성을 보였고 개복숭아꽃과 분홍매화 클로로포름층도 0.5 mg/mL 농도에서 각각 49, 30%의 항균 효과를 나타냈다. 3종의 꽃추출물들은 P. aeruginosa에 대해서도 항균 효과를 보였다. 개복숭아꽃 클로로포름층과 분홍매화 클로로포름층은 0.5 mg/mL 농도에서 각각 36, 30%의 항균활성을 보였다. 이 추출물들은 S. epidermidis와 E. coli에 대해서는 항균 활성을 보이지 않았다. 3종의 꽃추출물들은 HaCaT cell의 생존에 크게 영향을 미치지 않았다. 분홍매화 증류수층은 20, 40 μg/mL 농도에서 항산화 효과를 보였다. 분홍매화 에틸아세테이트층도 40 μg/mL에서 항산화 효과를 보였는데 이는 글루타치온 보다 우수하였다. 꽃추출물들은 B16F10 cell의 생존율에는 영향을 미치지 않았다. 꽃추출물들의 미백 효과는 개복숭아꽃 클로로포름층 40 μg/mL에서 18%가 나타났다. 이러한 결과들을 바탕으로 3종의 꽃추출물들은 항균 활성과 항산화, 미백 효과가 있는 원료로 판단할 수 있었다. In this study, we investigated the antibacterial, antioxidant, and whitening effects of Prunus persica Batsch var. davidiana Max. (Feral Peach) and Prunus mume (white and pink) flowers. The extracts of the three kinds of flowers showed antibacterial activity against Staphylococcus. aureus. The chloroform fractions of the white Prunus mume, Feral Peach, and pink Prunus mume flowers exhibited antibacterial activities of 84, 49, and 30%, respectively, against Staphylococcus. aureus at a concentration of 0.5 mg/mL. The flower extracts of the three species also exhibited antibacterial effects against Pseudomonas. aeruginosa. The chloroform fractions of the Feral Peach and pink Prunus meme flowers exhibited antibacterial activities of 36 and 30%, respectively, at a concentration of 0.5 mg/mL. These extracts did not exhibit any significant antibacterial activity against Staphylococcus. epidermidis and Escherichia. coli. The extracts of the three kinds of flowers did not significantly affect the survival of HaCaT cells. The distilled water fraction of the pink Prunus mume flower extract exhibited antioxidant effects at concentrations of both 20 and 40 μg/mL. The ethyl acetate fraction of the pink Prunus mume flower extract exhibited an antioxidant activity superior to glutathione at a concentration of 40 μg/mL. The flower extracts did not significantly affect the survival rate of B16F10 cells. The chloroform fraction of the Feral Peach flower exhibited a whitening effect of 18% at a concentration of 40 μg/mL. Based on these results, we conclude that the three kinds of flower extracts are raw materials exhibiting antibacterial, antioxidant, and whitening effects.

This research project focused on the production of hydrogen through ammonia decomposition reactions while investigating how the reactivity of this process varies when employing different catalysts. Several metal oxide supports (Al₂O₃, La₂O₃, CeO₂) were utilized as catalysts, with active metals from both the transition metal group (Co, Ni, Fe, Cr, Cu) and the noble metal group (Ru, Rh, Pd, Pt) impregnated onto these supports. Furthermore, the study examined how the reactivity evolves with changes in reaction temperature when employing the prepared catalysts. Additionally, the research delved into the distinctive activation energies associated with each of the catalysts. In this research, In the noble metal catalyst system, the order of high activity for ammonia decomposition reaction to produce hydrogen is Ru > Rh > Pt ≈ Pd. In the transition metal catalyst system, the order of high activity is Co > Ni > Fe > Cr > Cu.
