Using a multiple mediation model, this study examines the two types of cognitive emotional regulation strategies and parenting stress as mediators in the relationship between grit and postpartum depression. Two hundred and thirty-one first-time mothers with infants and toddlers aged 0-2 years participated and the self-reported data were analyzed by Process macro (Model 80). The results showed that there was no direct effect of grit on postpartum depression but both simple and double mediating effects of maladaptive cognitive emotional regulation strategies and parenting stress were significant, The relation between grit and postpartum depression was further mediated by adaptive cognitive emotional regulation strategies and parenting stress. These findings indicate that grit can protect first-time mothers from postpartum depression by enhancing cognitive emotional regulation strategies, and destressing parenting stress. These findings are further discussed in light of grit as positive psychological resources for first-time mothers’ adaption and well-being.

곽호경,Kwak, Hyo Gyoung 대한토목학회 1994 대한토목학회논문집 Vol.14 No.1

본 논문은 철근콘크리트와 프리스트레스트 콘크리트 보의 시간의존적 거동해석에 관한 내용으로 재령-보정 유효 탄생계수법에 토대를 두고 단면 내 힘의 평형관계와 변형의 Compatibility 조건을 사용한 반복해석을 통해 부재의 거동을 파악하였다. 콘크리트의 전 단면이 유효하고 부재가 선형 탄생체로 거동하며 강재의 효과는 단지 환산단면적 개념에 따라 해석시 강성만으로 보정되는 기존의 해석방법과는 달리 모든 재료가 고유의 성질을 유지할 수 있도록 함께 고려하며 균열의 영향도 동시에 고려함으로써 모든 하중조건에서 보다 정확한 결과를 얻을 수 있도록 하였다. 특히 예제해석을 통해 시간에 따른 각 재료의 응력 재분배, 장기처짐의 발생 등 시간의존적 거동에 영향을 미치는 여러 인자의 비교 검토와 균열의 영향분석을 하였으며 설계시 보다 정확하고 합리적으로 이들의 효과를 고려할 수 있도록 하였다. This paper deals with the time-dependent analysis of reinforced and prestressed concrete beams. Based on the age-adjusted effective modulus method, the structural behavior in accordance with time is analyzed using the force equilibrium and strain compatibility condition within a typical section. Unlike most of presented approaches adopting some assumptions, such as non-cracking of concrete and consideration of steel effect as a transformed concrete area only, more accurate results can be obtained at all loading conditions since all materials are considered together so as to be maintained their given properties and the cracking effect is included at the same time. Several parameter studies are conducted with the objective to identify the significance of various effects on the time-dependent response of concrete members, i.e., stress re-distribution of each material and occurrance of long-term deflection, etc. Moreover, the obtained results can be used at design and/or construction stage for the purpose of more accurate prediction of structural response with time.

곽호경,임은조,김복주 한국스포츠학회 2022 한국스포츠학회지 Vol.20 No.1

본 연구는 소근육운동프로그램이 노인의 인지기능과 우울 뇌파활성도에 미치는 영향을 알아 보는데 목적이 있다. 연구를 위하여 S시 M구에 거주하는 65세 이상 남녀노인을 대상으로 실험집단 15명 통제집단 15명으로 분석하였다. 소근육운동프로그램 효과 검정을 위하여 MMSE-DS, 우울 질문지, 전전두엽(Fp1, Fp2) 뇌파검사를 실시하였다. 그 결과, MMSE지수 변화는 실험집단은 사전에 비해 사후에 평균값이 유의미(p〈.01)하게 높아졌고 통제집단은 유의미(p〈.05)하게 낮아졌다. 우울지표의 변화는 실험집단에서 사전에 비해 사후에 유의미(p〈.05)하게 낮게 나타났다. 우울과 관련 전전두엽 알파파 비대칭지표의 변화도 통제집단에 비해 실험집단에서 사전에 비해 사후에 0점에 더 가까워진 유의미한(p〈.05) 차이를 보였다. 또한, 인지기능 관련 고유리듬 MDF지표 변화는 Fp1영역에서 사전에 비해 사후에 실험집단에서 유의미(p〈.05)한 차이로 증가하였다. 이상의 결과는 소근육운동프로그램 수행 시 말초신경의 자극이 혈액순환과 뇌 감각신경을 자극 신체기능의 활성화로 우울을 감소시키고 노인의 인지기능 향상에도 도움을 줄 수 있을 것으로 사료된다. The purpose of this study is to investigate the effect of fine motor exercise program on cognitive function and depressive brain wave activity in the elderly. For this study, 15 people in the experimental group and 15 in the control group were analyzed for the elderly men and women aged 65 and over living in M-gu, S city. MMSE-DS, depression questionnaire, and prefrontal(Fp1, Fp2) EEG tests were performed to test the effect of the fine motor program. As a result, the MMSE index change in the experimental group was significantly higher (p<.01) after the post compared to the prior, and the control group was significantly lowered (p<.05). Compared to that, it was significantly lower (p<.05) post-mortem. The change in the prefrontal alpha wave asymmetry index related to depression also showed a significant (p<.05) difference in the experimental group, which was closer to 0 after the test compared to the control group. In addition, the change in the eigenrhythm MDF index related to cognitive function increased with a significant (p<.05) difference in the experimental group after the Fp1 domain compared to before. The above results suggest that stimulation of peripheral nerves stimulates blood circulation and sensory nerves in the brain when performing a fine motor program, reduces depression by activating bodily functions, and can help improve cognitive function in the elderly.

This study investigated whether the relationship between SNS use purpose (relationship pursuit, information pursuit, entertainment pursuit) and successful aging is mediated by loneliness. The mediating model is examined using PROCESS Macro v3.5. The mediating model was examined for 328 domestic older adults aged 65-79 years(M=67.77, SD=2.95) using SNS. The results indicated that the mediating effects of loneliness were significant in the relationship between the three types of SNS use and successful aging but in different ways. In other words, it was found that SNS use for relationship pursuit and SNS use for information pursuit in older adults not only directly affects successful aging, but also indirectly affects successful aging by lowering loneliness. On the other hand, the indirect effect of loneliness was positive for SNS use in the pursuit of relationships and information but negative for entertainment. These findings suggest that, contrary to the other two types of SNS use, the use of SNS for entertainment reduces successful aging by increasing loneliness. This study revealed a mechanism by which the purpose of SNS use in older adults affects successful aging through loneliness, and confirmed that the relationship between these mechanisms may vary depending on the purpose of SNS use.

The present study was conducted to examine metabolic risk factors and total antioxidant capacity (TAC) of Korean females living in Seoul and to investigate the relationship between the metabolic risk factors and serum TAC. A total of 353 females aged between 20 and 64 participated in the study. Obesity indicators, blood pressure, serum lipid profile and fasting blood glucose were measured as metabolic risk factors. Ferric reducing antioxidant power (FRAP) assay was employed to determine serum TAC of subjects. Obesity indicators such as body mass index, waist circumference and waist-hip ratio were significantly higher in the participants aged ≥ 50 y (older group) than in the participants aged 20-49 y (younger group) (p < 0.001). Blood pressure, serum total cholesterol (TC), triglyceride (TG) and fasting blood glucose were also significantly higher in the older group than in the younger group (p < 0.001), demonstrating significant positive correlations between age and MS risk factors. The association between FRAP and MS risk factors were also investigated. FRAP values showed significant positive correlations with age (p = 0.001), serum TG (p = 0.002) and TC (p = 0.03). A tendency of positive association between FRAP and waist circumference was observed without any significant difference (p = 0.06). Increased serum FRAP with central obesity and serum lipids may be interpreted as results of activation of antioxidant defense system against oxidative stress induced by metabolic syndrome (MS) constituent factors. However, to verify the function of FRAP as a potential biomarker of susceptibility to MS various contributors to the plasma antioxidant capacity and their biological relevance related to MS should be elucidated further.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as very healthy, healthy, normal, and unhealthy, respectively. As compared to the other 3 groups, unhealthy group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, very healthy group reported longer sleeping time than unhealthy group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: Regularity of meal time (P < 0.01), Eat protein foods more than twice a day (P < 0.001), Eat vegetables (P < 0.01), Eat fruit and fruit juice (P < 0.01), Eat vegetable oil added foods (P < 0.01), Eat seaweed (P < 0.01), Eat breakfast (P < 0.01), Modulation in animal fat and high in cholesterol intake (P < 0.01). Particularly, higher proportion of subjects answered very healthy had higher frequencies (6-7 times/ week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health. (Korean J Community Nutr 16(6) : 672~682, 2011)
