Purpose: The purpose of this study is to construct and test a structural equation model of posttraumatic growth (PTG) of earthquake victims based on Tedeschi and Calhoun's model (2004). Methods: Data were collected from 195 earthquake victims living in K. City. The exogenous variables include distress perception, resilience, and social support, and the endogenous variables include intrusive rumination, deliberate rumination, and posttraumatic growth. For data analysis, descriptive statistics, factor analysis, and structural equation modeling were performed. Results: The modified model showed a good fitness to the data. Moreover, 6 of the 9 paths of the final model were statistically significant, which include PTG affected by deliberate rumination (${\beta}=.58$, p<.001), resilience (${\gamma}=.18$, p=.001), and distress perception (${\gamma}=.20$, p=.002). These predictors explain 51.8% of variance in posttraumatic growth. Conclusion: Based on the results of this study, it is necessary to develop and disseminate preventive intervention programs to increase the resilience of earthquake-prone communities. In addition, after exposure to a community-scale traumatic event such as earthquake, we should provide social supports to alleviate distress perception and transition from intrusive rumination to deliberate rumination so that we can seek new meaning from the earthquake and facilitate posttraumatic growth.

12세로 추정된 시설아동의 2년간 지속된 구토행위를 행동치료 방법을 사용하여 치료하였다. 이 아동의 구토행위 형태는 바닥에 음식을 토해 낸 후 $2{\sim}3$ 차례에 걸쳐 토한 음식을 다시 먹는 것이었다. 치료 방법으로 일단 토해 낸 음식을 다시 먹지 못하도록 하기 위해 음식을 토할 때마다 즉시 토한 음식을 치웠다. 일단 위에 들어간 음식을 역류시켜 바닥에 토하지는 않았지만 입안에서 씹을때는 입을 강제로 벌려 입안의 음식물을 제거하였다. 치료는 약 3주간 지속되었는데 식사 후 2시간 30분동안 치료전에는 평균 46회($범위=30{\sim}62회$)토했고 치료 후에는 평균 1.12회($범위=0{\sim}10회$)로 감소하였다. 치료 종료 후 10개월이 지난 뒤에도 아동의 구토행위는 재발되지 않았다. 따라서 토하는 행위를 강화시키는 요인인 '토해낸 음식을 다시 먹는 기회'를 박탈한 본 연구의 치료방법은 구토행위의 치료에 매우 효과가 높은 것으로 나타났다.

본 연구는 대학 및 대학원생을 대상으로 향유신념과 반추, 긍정정서의 관계를 확인함으로써, 긍정정서를 증진시킬 수 있는 방안을 실증적으로 제안하고자 하였다. 이를 위해 서울 소재 대학에 재학 중인 대학 및 대학원생 235명을 대상으로 향유신념, 반추, 긍정정서를 측정하는 질문지를 실시하였다. 구조방정식 모형분석을 실시한 결과, 대학 및 대학원생의 향유신념은 긍정정서에 긍정적인 영향을, 반추에는 부정적인 영향을 미쳤고, 반추는 긍정정서에 부정적인 영향을 끼쳤는데, 향유신념과 긍정정서의 정적 관계는 반추에 의해 부분 매개되는 것으로 나타났다. 본 연구의 결과는 긍정정서를 높이기 위한 향유하기 방략의 효과를 확인하는 동시에 그 기제를 밝혔다는 점에서 의의가 있다. 단순히 향유신념에 초점을 두는 것보다 긍정정서에 대한 반추의 영향력을 함께 고려할 때 더 효과적으로 긍정정서의 향상을 기대할 수 있을 것이다.

This study aimed to examine the effect of adolescents' perceived parental blame (criticism) on learned helplessness and to examine whether maladaptive metacognitive beliefs and rumination sequentially mediate the relationship between parental blame and learned helplessness. The participants were 316 adolescents (Mean age=16.7, SD=0.75; 137 male, 179 female) attending grades 1st and 2nd in high school in South Korea. The participants were selected using a snowball sampling method, while the data was collected via an online self-report questionnaire. This survey was completed by the participants and analyzed using SPSS 28.0, Amos 26.0 (IBM Co., Armonk, NY), and PROCESS macro version 4.2 (Model 6; Hayes, 2022). The main results are summarized as follows. Firstly, the adolescents' perceived paternal and maternal blame indicated significant direct effects on learned helplessness. Secondly, rumination mediated the effect of paternal and maternal blame on learned helplessness. Lastly, paternal and maternal blame significantly affected learned helplessness through the sequential mediating effects of maladaptive metacognitive beliefs and rumination. This study elucidates the causal structure among the various factors influencing learned helplessness in adolescents, focusing on parental blame, maladaptive metacognitive beliefs, and rumination. Furthermore, considering the verified sequential mediating effects of maladaptive metacognitive beliefs and rumination in the relationship between adolescents' perceived parental blame and learned helplessness, these findings suggest that modifying maladaptive metacognitive beliefs may help to reduce learned helplessness among adolescents who perceive high levels of parental blame.

본 연구에서는 외상을 경험한 성인의 의도적 반추와 외상 후 성장 간의 관계를 확인하고, 삶의 의미가 의도적 반추와 외상 후 성장을 매개하는 모형에서 외상 강도의 조절효과가 있는지 검증하였다. 참여자는 외상 경험이 있는 남녀 성인 318명이었다. 조절된 매개효과는 PROCESS Macro 3.5 모델 7로 분석하였다. 연구 결과, 외상 경험이 있는 성인의 의도적 반추는 외상 강도, 삶의 의미 및 외상 후 성장 모두와 정적 상관이 있었으며, 삶의 의미도 외상 후 성장과 정적 상관이 있었다. 외상 후 성장에 대한 조절된 매개효과 분석에서는 의도적 반추와 외상 강도의 상호작용효과가 유의했으며, 의도된 반추의 조건부 간접효과는 경험한 외상 강도 수준이 높은 집단에서만 유의하였다. 이런 결과는 의도적 반추를 하는 외상 경험이 있는 사람이 삶의 의미 느끼게 되어 성장하게 될 가능성이 크다는 것을 시사하며, 그런 영향은 외상 강도가 강한 경우 발생한다는 것으로 암시한다. 결론적으로 심한 외상을 경험한 사람들에게서 사건에 대한 의도적 반추가 외상 후 성장을 이끌고, 그 과정에서 삶의 의미를 깨닫는 것이 도움이 될 수 있다는 결과를 얻었다.

Sixteen mature sheep were fed chaffed orchardgrass hay once a day. Jaw movement of the sheep was recorded for 24 hours before slaughter. Four sheep were slaughtered either prior to eating, 2, 8 or 16 hours after the commencement of eating to measure digesta pool size and particle size distribution in the reticulo-rumen. Eating time was restricted to 120 minutes. Rumination time and actual chewing time during rumination increased with time after the meal. Mean dry matter (DM) pool size before and 2 hours after the meal were 1.36 and 2.45 times of DM intake, respectively. The proportion of large particle (>1.18 mm; LP) in the DM ingested during the meal was caculated to be about 70%. The mean DM and LP pool sizes per DM intake and the mean proportion of LP in the DM pool decreased with time after the meal. There were close negative relationships between either DM or LP pool sizes per DM intake and the chewing activities either expressed as time spent rumination, actual chewing time during rumination or total actual chewing time(total of eating time and actual chewing time during rumination). The difference between DM intake and LP pool size were assumed to be LP degradation in the present experiment, and correlated positively with the chewing activities. A large proportion of the digesta load was comprised of small particles, in excess of the daily intake.

Purpose: The purpose of this study is to construct and validate a posttraumatic growth structural model for firefighters based on Calhoun and Tedeschi's model (2006). Methods: The research data was collected from 200 firefighters working in Gyeongsang-do, Jeolla-do, and Gyeonggi-do. The participants completed an anonymous survey asking about ego-resilience, active coping, family support, organizational support, self-exposure, deliberate rumination, posstraumatic stress and posttraumatic growth. Results: The model selected as a final model was the one that supports 10 hypotheses out of 13 hypotheses. In the final model, deliberate rumination (β=.59, p<.001) had a significant effect in the posttraumatic growth of firefighters. Active coping, organizational support, self-exposure, ego-resilience and posttraumatic stress had a significant indirect effect. The explanatory power of these variables was 36.0%. Conclusion: The results of the survey show that it is important to develop a strategy to strengthen deliberate rumination. In addition, encouraging deliberate rumination through organizational support and self-exposure can promote posttraumatic growth of firefighters.

Hoof health management plays an important role in dairy farms because lameness can impact productivity via decreased milk yield, reproduction rate, and increased culling rate. Regular hoof trimming can help reduce the incidence of hoof diseases in dairy cows. However, its effects on healthy dairy cows remain unclear. This study investigated the effects of hoof trimming on milk yield, rumination time, and activity in healthy Holstein and Jersey cows. Fourteen cows (7 Holstein and 7 Jersey) without lameness were used in this study. We trimmed the cows and collected data from 3 days prior to 9 days after hoof trimming. Milk yield, rumination time, and activity were measured using automatic milking and health monitoring systems. Milk yield and rumination time decreased, whereas activity level increased on the trimming day compared to the previous days in both breeds, although the difference was not significant. On the days after hoof trimming, milk yield, rumination time, and activity recovered to normal. Especially in Holstein cows, a temporary increase in milk yield was observed compared to that in the pre-trimming period. Hoof trimming did not negatively affect the productivity of dairy cows of either breed. Furthermore, productivity can temporarily increase.

In the present experiment, the relationship between rumination and the amount of roughage eaten by sheep was investigated in detail. Daily time spent eating was obviously changed along with an increase or decrease in daily hay intake. Daily time spent ruminating and daily number of boli regurgitated was also linearly increased or decreased with an increase or decrease of daily hay intake, and there were regression lines between daily amount of hay eaten and daily ruminating time or daily number of boli with statistical significant coefficients. Cyclic rate (total rumination time(s)/number of boli regurgitated) and daily number of rumination periods did not change in an outline along with the changes in daily hay intake. From these results, it can be suggested that daily dry matter intake by sheep could be presumed by measuring daily time spent ruminating when they were fed only roughage feed.

The study introduces and validates a model of post-traumatic growth among parents of children with special needs. The model incorporates cognitive processes, coping strategies, and sociocultural factors as intra-personal variables. The statistical analysis unveiled significant pathways that connect the factors, explaining 71% of the variance associated with post-traumatic growth. The study highlighted intentional reflection and robust decentralization skills as crucial factors that predict post-traumatic growth. Deliberate rumination functioned as a mediating factor, reducing the impact of trauma and facilitating post-traumatic growth, while social support played a crucial role in initiating purposeful rumination. The study findings indicate that the effect of self-disclosure on post-traumatic growth is not direct but rather indirect, as it is mediated by its influence on social support and deliberate rumination. The study underscores the significance of examining particular characteristics of social support networks and suggests integrating additional variables for future research, such as gender, types of traumatic events, and the age of children with disabilities.
