본 연구는 서울 및 경기 지역의 주부 396명을 대상으로 결혼불만족이 스트레스 반응에 미치는 영향에서 포커싱적 태도의 매개효과를 알아보고자 실시되었다. 또한 주부의 결혼불만족과 스트레스 반응 관계에서 포커싱적 태도의 하위요인별 매개효과를 밝혀 주부의 효과적인 스트레스 감소를 위한 보다 구체적인 포커싱적 태도의 활용 방안을 탐색하고자 하였다. 본 연구의 결과는 다음과 같다. 첫째, 결혼불만족과 행동적 스트레스, 신체적 스트레스 및 정서적 스트레스 반응과는 유의한 상관을 보이는 것으로 나타났다. 그러나 결혼불만족과 포커싱적 태도의 하위 요인 간의 상관에서는 체험과정 주의와 음미하기와 체험 지각하기에서만 유의한 상관을 보이고 있었다. 둘째, 결혼불만족이 스트레스 반응(행동, 신체, 정서)에 미치는 영향에 포커싱적 태도 중 체험과정 주의와 음미하기, 체험과정 수용과 행동하기, 적절한 거리두기는 매개하지 않은 것으로 나타났다. 그러나 체험 지각하기는 결혼불만족과 행동적, 신체적 그리고 정서적 스트레스 반응과의 관계에서 유의하게 부분매개하고 있었다. 이러한 결과를 통해 주부의 결혼불만족이 스트레스 반응에 영향을 미치고 있었으며 그 과정에 체험 지각하기가 매개하고 있음을 밝혀냈다. 이 연구는 향후 주부의 결혼불만족이 스트레스 반응에 미치는 영향에서 포커싱적 태도의 교육 및 다양한 활용에 관한 후속 연구를 촉진시킬 수 있다는 데 의의가 있다. This study aimed to examine the mediating effects of housewives’ focusing manners on the effects of marriage dissatisfaction on stress reaction. In addition, the study sought to determine the mediating effects of focusing manner by sub-factor in the marriage dissatisfaction and stress reaction relationship in housewives to explore the method of using a more specific focusing manner with the aim of effectively reducing such stress. Hypotheses were established as follows. First, housewives’ marriage dissatisfaction will have a relationship with stress reaction(behavioral, physical, emotional) and the sub-factors of focusing manners. Second, the focusing manner will mediate the effects of housewives’ marriage dissatisfaction on stress reaction. To verify the above hypotheses, 396 mothers in the Seoul and Gyeonggi regions were surveyed using the Korean Marital Satisfaction Inventory(K-MSI), the Stress Reaction Scale, and the Korean Focusing Manner Scale(KFMS). Data were analyzed using a frequency analysis, Pearson’s correlation analysis, and a regression analysis. The findings of this study are outlined as follows. First, there was a significant correlation between marriage dissatisfaction and behavioral stress, as well as between physical stress and emotional stress reaction. However, in the relationship between marriage dissatisfaction and the focusing manner`s sub-contractors, there is a significant correlation only among attention to the experience process, appreciation, and perceptions of experience. Second, the effects of marriage dissatisfaction on stress reaction(behavioral, physical, emotional), focusing manner, attention to the experience process and appreciation, acceptance of the experience process and behaving, and an appropriate distancing did not mediate. However, perceptions of experience significantly partially mediated the relationship between marriage dissatisfaction and behavioral, physical, and emotional stress reactions. Thus, it was found that housewives’ marriage dissatisfaction influenced stress reactions, as well as that perceptions of experience mediated that process. This study will include further follow-up studies on the education about and diverse uses of focusing manners in the effects of housewives’ marriage dissatisfaction on stress reaction.

본 연구는 일부 치위생과 학생이 경험하는 스트레스 반응과 극복력 수준을 파악하고, 스트레스 반응이 극복력에 미치는 영향을 조사하였다. 2016년 7월 11일부터 2016년 7월 29일까지 일부 지역 치위생과 재학생 274명을 대상으로 설문지를 수집하였다. 수집된 자료는 IBM SPSS Statistics ver.21.0 프로그램을 이용하여 descriptive statistics, t-test, One-way ANOVA, Pearson correlation coefficient, multiple regression으로 분석하였다. 연구 결과, 치위생과 학생의 스트레스 반응 수준은 5점 만점 중에 2.59점이고, 극복력 수준은 7점 만점 중에 4.47점이었다. 스트레스 반응과 극복력은 피로, 긴장, 좌절, 분노, 우울, 공격성(p<0.001), 신체화(p<0.05)에서 유의한 부적 상관관계가 나타났다. 즉, 극복력이 낮을수록 스트레스 반응 정도는 높아진다. 극복력에 영향을 미치는 스트레스 반응의 요인은 우울과 신체화로, 이들 변인은 25.6%(R2=0.256)의 설명력을 나타냈다. 따라서 치위생과 학생의 극복력을 증진시키기 위해서는 스트레스 반응 수준을 조사하여 우울과 신체화 반응이 높은 학생에 대해서는 더욱 관심을 가지고, 스트레스 반응을 조절하기 위한 노력이 필요하다고 사료된다. This study examined the stress reaction, resilience levels, and the effects of the stress reaction on the resilience among dental hygiene students. From July 11, 2016 to July 29, 2016, questionnaires were collected from 274 dental hygiene students in several areas. The collected data were analyzed by descriptive statistics, t-test, One-way ANOVA, Pearson correlation coefficient, and multiple regression using SPSS Statistics ver.21.0. The stress reaction level of dental hygiene students was found to be 2.59 out of 5 points and the resilience level was 4.47 out of 7 points. Thestress reaction and resilience showed a significant negative correlation in Fatigue, Tension, Frustration, Anger, Depression, Aggression(p>0.001), and stomatization(p>0.05). In other words, the lower the resilience, the higher the stress reaction.The factors of stress reaction influencing the resilience were depression and somatization, which explained 25.6%(R2=0.256). Therefore, to enhance the resilience of dental hygiene students, it is important to investigation the stress reaction and there should be more concern with students who havehigher depression and stomatization. In addition, efforts to control the stress reaction are needed.

The purpose of this study is to analyze photochemical activity of nursery seedlings under drought stress, using chlorophyll fluorescence reaction analysis. Young nursery seedlings of tomato (Lycopersicon esculentum Mill.) and cucumber (Cucumis sativa L.), were grown under drought stress for 8 days. Analysis of chlorophyll fluorescence reaction (OJIP) and parameters, were performed to evaluate photochemical fluctuation in nursery seedlings under drought stress. Chlorophyll fluorescence reaction analysis showed maximal recorded fluorescence (P) decreased from the 5 day after treatment in tomato seedlings, while an amount of chlorophyll fluorescence increased at the J-I step. Thus, physiological activity was reduced. In cucumber seedlings, maximal recorded fluorescence (P) and maximal variable fluorescence (FV) lowered from the 4 day after treatment, and chlorophyll fluorescence intensity of J-I step increased. Chlorophyll fluorescence parameter analysis showed electron transfer efficiency of PSⅡ and PSⅠ were significantly inhibited with decreasing ET2O/RC and RE1O/RC from the 5 day after treatment, in tomato seedlings and from the 4 day after treatment, in cucumber seedlings. ET2O/RC and PIABS significantly changed. In conclusion, 6 indices such as FV/FM, DIO/RC, ET2O/RC, RE1O/RC, PIABS and PITOTALABS were selected for determining drought stress in nursery seedlings. Drought stress factor index (DFI) was used to evaluate whether the crop was healthy or not, under drought stress. Cucumber seedlings were less resistant to drought stress than tomato seedlings, in the process of drought stress. 본 연구는 엽록소형광반응 분석을 이용하여 건조스트레스에 의한 공정육묘의 광화학적 활력을 분석하였다. 토마토와 오이 공정육묘를 8일 동안 건조스트레스 처리를 하였다. 엽록소형광반응 (OJIP)과 매개변수 분석을 통해 건조스트레스로 인한 작물의 광화학적 변동을 평가하였다. 엽록소 형광반응 (OJIP) 분석 결과, 토마토는 처리 후 5일부터 최대 형광량 (P)이 감소한 반면 J-I 단계에서는 엽록소 형광량이 증가하였다. 따라서 생리적 활력이 감소한 것을 알 수 있었다. 오이의 경우 처리 후 4일부터 최대 형광 (P) 및 변동 형광량 (FV)이 낮아지고 J-I 단계의 엽록소 형광 수치가 증가하였다. 엽록소 형광 매개변수 분석한 결과 토마토는 처리 후 5일부터 특히 ET2O/RC와 RE1O/RC가 감소하면서 광계II와 광계I의 전자전달효율이 유의적으로 낮아진 것으로 보인 반면 오이는 처리 후 4일부터 ET2O/RC와 PIABS가 상당히 변화하였다. 결론적으로 FV/FM, DIO/RC, ET2O/RC, RE1O/RC, PIABS, PITOTALABS 6개의 지표가 공정육묘의 건조스트레스를 판단하는 지표로 선정되었다. 건조스트레스지수 (DFI)를 통해 건조스트레스로 인한 작물별 건전성 평가를 하였고 오이의 경우 토마토에 비해 건조 저항성이 낮은 것으로 판단되었다.

유아의 스트레스 반응에 대한 연구: 시간의 경과에 따른 변화를 중심으로

송하나 ( Ha Na Song ) 한국유아교육학회 2013 유아교육연구 Vol.33 No.6

본 연구에서는 유아가 스트레스 상황에서 나타내는 반응의 유형을 살펴보고 이러한 반응들이 시간의 변화에 따라 어떻게 달라지는지 알아보았다. 연구 대상은 만 5세 유아 40명(남아22명, 여아18명)이었으며 이 유아들은 유치원에 구성된 관찰실을 어머니와 방문하였다. 유아들은 어머니가 구석에서 지켜보는 가운데 자유 놀이를 수행하다가 낯선 실험자가 예고 없이 들어와서 가지고 놀던 장난감을 모두 치워버리는 스트레스 상황이 제시되었다. 스트레스 상황은 3-5분간 지속되었으며 유아가 보인 스트레스 반응은 두 명의 코더가 분류하였고 시간의 흐름에 따라 초반, 중반, 후반으로 나누어 평균과 표준편차를 구하였다. 연구 결과, 유아들은 스트레스 상황에서 적응적 반응과 짜증, 저항, 위축 반응을 나타냈으며, 짜증을 포함한 부적 반응에서 유의한 성차가 보고되었다. 또한, 적응적 반응에서는 시간의 경과에 따른 차이가 나타나지 않았으나 짜증은 초반부에서 중반부까지 증가하다 후반부에서 감소하였으며, 저항 반응은 초반에 가장 높았으나 후반으로 갈수록 감소하였다. 반면, 위축 반응은 초반보다는 후반부에 높은 것으로 나타났다. 이러한 결과들은 유아의 스트레스 반응의 변화를 상세히 설명함으로써 적절한 자기 조절 책략을 적용하는데 시사점을 제시할 것으로 생각된다. This study examined adaptive and maladaptive types of reactions to stress stimuli in preschool children, and time-series changes in their reactions. In addition, gender differences in reaction to stress were also examined. Forty children all 5 years of age participated in an experiment in which the experimenter disrupted the children`s playing with toys. Results show that resistant reactions were salient early in the experiment session, and withdrawals were frequently observed in the later period of the experiment, and more so in girls than in boys. There was no significant gender difference in adaptive reactions. These findings are discussed in terms of the fight-flight processes of stress, and suggestions are given for early childhood intervention.

This study is to identify the impact of focusing manner on reduction in stress reaction among middle-aged male teachers. Therefore, from 2013 November 11 to 23, data on 220 middle-aged male teachers of middle and high schools in Seoul and Gyeonggi metropolitan areas were analyzed. As a result of correlation analysis, among the sub-variables of focusing manner, stress reaction showed a significant positive correlation with feeling, savoring, experiential attention, noticing. On the other hand, experience acceptance-expression, and relaxation showed a significant negative correlation with stress response. In the results of a stepwise regression analysis on the effect of each sub-variables of the focusing manner on the stress reaction, noticing and feeling positively predicted the stress reaction, and experience acceptance-expression negatively significantly predicted the stress reaction. This study is significant in that it confirmed the change in stress management ability of middle-aged teachers according to the type of focusing manner, and through this results, the study presented the necessity of focusing training and education to improve stress management ability. 본 연구는 포커싱적 태도의 각 하위변인들이 중년 남성 교사의 스트레스 반응 감소에 차별적 영향을 미치는 지에 대해 알아보고자, 2013년 11월 11일부터 11월 23일까지 서울·경기 지역의 중 · 고등학교의 중년 남성 교사 220명을 대상으로 수집한 자료를 분석하였다. 상관분석 결과, 포커싱적 태도의 하위변인들 중에서 느껴보기, 음미하기, 체험 주의 집중하기, 알아차리는 스트레스 반응과 정적 상관이 유의한 것으로 나타났다. 반면, 체험 수용과 표현하기 및 여유갖기는 스트레스 반응과 유의한 부적상관을 나타냈다. 포커싱적 태도의 각 하위요인이 스트레스 반응에 미치는 효과에 대한 단계적 회귀분석 결과에서는 알아차리기와 느껴보기는 스트레스 반응을 정적으로 유의하게 예측했으며, 체험 수용과 표현하기는 스트레스 반응을 부적으로 유의하게 예측하는 것으로 나타났다. 본 연구는 포커싱적 태도의 종류에 따른 중년교사의 스트레스 관리 능력 변화를 확인하고, 이를 통해 스트레스 관리 능력 향상을 위한 포커싱적 훈련, 교육의 필요성을 제시했다는 점에서 의의가 있다.

이효건,Saichit Khummuang,윤현희,박정웅,최재영,신택순,조성근,김병우,서자겸,김명후,박태섭,조병욱 아세아·태평양축산학회 2019 Animal Bioscience Vol.32 No.8

Objective: Among stress responses, the unfolded protein response (UPR) is a well-known mechanism related to endoplasmic reticulum (ER) stress. ER stress is induced by a variety of external and environmental factors such as starvation, ischemia, hypoxia, oxidative stress, and heat stress. Inositol requiring enzyme 1α (IRE1α)-X-box protein 1 (XBP1) is the most conserved pathway involved in the UPR and is the main component that mediates IRE1α signalling to downstream ER-associated degradation (ERAD)- or UPR-related genes. XBP1 is a transcription factor synthesised via a novel mechanism called ‘frame switch splicing’, and this process has not yet been studied in the horse XBP1 gene. Therefore, the aim of this study was to confirm the frame switch splicing of horse XBP1 and characterise its dynamics using Thoroughbred muscle cells exposed to heat stress. Methods: Primary horse muscle cells were used to investigate heat stress-induced frame switch splicing of horse XBP1. Frame switch splicing was confirmed by sequencing analysis. XBP1 amino acid sequences and promoter sequences of various species were aligned to confirm the sequence homology and to find conserved cis-acting elements, respectively. The expression of the potential XBP1 downstream genes were analysed by quantitative real-time polymerase chain reaction. Results: We confirmed that splicing of horse XBP1 mRNA was affected by the duration of thermal stress. Twenty-six nucleotides in the mRNA of XBP1 were deleted after heat stress. The protein sequence and the cis-regulatory elements on the promoter of horse XBP1 are highly conserved among the mammals. Induction of putative downstream genes of horse XBP1 was dependent on the duration of heat stress. We confirmed that both the mechanisms of XBP1 frame switch splicing and various binding elements found in downstream gene promoters are highly evolutionarily conserved. Conclusion: The frame switch splicing of horse XBP1 and its dynamics were highly conserved among species. These results facilitate studies of ER-stress in horse.

This study is a basic study on the stress reaction of children.(Children) and technical questionnaire (teacher) for infants (22boys, 16girls, and a total of 38students and 5teachers) who spent most of the day in kindergarten. The purpose of this study is to clarify the relationship between stress level and basic life ability and athletic ability. Children "s stress response was measured/analyzed 4 times a day using saliva amylase monitor (Nipro), and basic life ability and athletic ability were measured through teacher" s participation observation and questionnaire. The analysis tool is SPSS v20 for Windows. In the analysis method, cluster analysis and each measurement value were expressed as mean and standard deviation, and t test and X² test were performed. The level of significance was set at p <.05 level. As a result, it was classified into three types (high, middle, low).There was a significant difference between the types. Salivary amylase activity values of all three types of group were elevated in the morning activity, descending after the nap, and rising again through the afternoon activity. There was no significant difference in the exercise capacity among the types, but the highest values were in the order of the active, low, and high activity groups. In relation to the child "s basic life ability, the activity level of saliva amylase was lower in children who had basic living ability and children who lived relatively freely in regular and stable living in home. Teachers" participation in basic life skills (5 items) was significantly higher in the upper group than in the lower group. The stress-strain and stress-level curves showed a significant change curve in the high-order group, while the low-order group showed only a simple change but not the significant difference.

Modeling reaction injection molding process of phenol-formaldehyde resin filled with wood dust

Lee, Jae-Wook,Kwon, Young-Don,Leonov, A.I. The Korean Society of Rheology 2008 Korea-Australia rheology journal Vol.20 No.2

A theoretical model was developed to describe the flow behavior of a filled polymer in the packing stage of reaction injection molding and predict the residual stress distribution of thin injection-molded parts. The model predictions were compared with experiments performed for phenol-formaldehyde resin filled with wood dust and cured by urotropine. The packing stage of reaction injection molding process presents a typical example of complex non-isothermal flow combined with chemical reaction. It is shown that the time evolution of pressure distribution along the mold cavity that determines the residual stress in the final product can be described by a single 1D partial differential equation (PDE) if the rheological behavior of reacting liquid is simplistically described by the power-law approach with some approximations made for describing cure reaction and non-isothermality. In the formulation, the dimensionless time variable is defined in such a way that it includes all necessary information on the cure reaction history. Employing the routine separation of variables made possible to obtain the analytical solution for the nonlinear PDE under specific initial condition. It is shown that direct numerical solution of the PDE exactly coincides with the analytical solution. With the use of the power-law approximation that describes highly shear thinning behavior, the theoretical calculations significantly deviate from the experimental data. Bearing in mind that in the packing stage the flow is extremely slow, we employed in our theory the Newtonian law for flow of reacting liquid and described well enough the experimental data on evolution of pressure.

연구는 인간에게 3차원 공간상에서 시청각 통합 환경을 만든 후 정신적 스트레스가 시각 자극을 통해 ERPs에 어떠한 영향을 미치는지를 정량적으로 분석하기 위하여 수행되었다. 이를 위하여, 정상 상태와 정신적 스트레스를 제시 상태를 구분하여 ERPs를 측정하였다. 실험은 정상상태의 남녀 10명의 피험자를 대상으로 하였고. 생체 신호는 Fpl, Fz, Cz. Pz, O1, O2의 영역에서 전자기적 영향을 받지 않는 차폐 공간에서 측정하였다. 그 결과 P300의 진폭은 스트레스를 제시한 경우에 좀더 커지고, 이때의 잠재기는 길어지는 결과를 얻었다 본 연구에서는 인간의 지각, 인지. 행동의 과정을 담당하는 뇌의 활동을 전위 변동으로 기록하여 정신적 스트레스의 영향을 측정하였다. 이러한 기초적 연구 검토를 통하여 인간의 제반 과정에 관한 뇌 기능의 이상을 평가 할 수 있을 것이라 기대된다. This research was performed to analyze quantitatively how spiritual stress affects some ERPs on human through sight stimulus after the settlement of visual and auditory integration environment in three dimension space. We measured ERPs in the normal state and spiritual stress sessions separately. The subjects were 10 normal men and women and vital signs was recorded from Fpl, Fz, Cz, Pz, O1, O2's scalps. The experiment was done in isolated room where electro-magnetic effect do not affect. The result showed that P300's amplitude was a little higher under stress session and latent period in this resulted in longer time. We recorded through voltage variation the activity of brain which is in charge of human's perception. cognition, process of action and evaluated the effect of spiritual stress. We expected that the result of this research can be used to evaluate the malfunction of brain.
