기후 변화로 인한 수온의 상승은 어류 서식지에 영향을 미친다. 수온의 변화는 어류 생리 거의 모든 부분에 영향을 미치는 것으로 알려져 있다. 기후 변화에 따른 수온의 상승은 산소 용해도의 감소 및 산소 운반 헤모글로빈의 결합 능 력의 감소로 인해 저산소증을 초래할 수 있다. 본 연구는 대서양 연어 (Salmo salar) 치어 성장의 최적수온 (15°C)보다 고 수온 (20°C)에 사육 시, 대서양 연어 치어의 건강상태를 평가 하기 위해 수행되었다. 평가 방법은 NGS RNAseq 분석방법을 이용하여 생체지표유전자를 개발하고, RT-qPCR 분석을 이용하여 생체지표유전자의 발현양상을 조사하는 것이다. 개발한 생체지표유전자로는 interferon alpha-inducible protein 27-like protein 2A transcript variant X3, protein L-Myc- 1b-like, placenta growth factor-like transcript variant X1, fibroblast growth factor receptor-like 1 transcript variant X1, transferrin, intelectin, thioredoxin-like, c-type lectin lectoxin-Thr1- like, ladderlectin-like 및 calponin-1 등이다. 선택된 생체지표 유전자는 NGS RNAseq 분석을 통해 수온변화에 민감하게 발현한 유전자들이며, RT-qPCR 분석을 통한 이들 유전자의 발현 양상은 NGS RNAseq 분석을 통한 발현 양상과 매우 유사하게 나타났다.

Purpose: This study aimed to observe coping strategies and career identity in nursing students, and examine the influence of coping strategy on career identity. Methods: Data from 329 third- and fourth-year nursing students was collected using structured self-reports questionnaires for two months. Descriptive statistics were calculated and the data analyzed with independent t-tests, Pearson correlation coefficients, and hierarchical multiple regression. Results: The nursing students scored highest on the passive coping style of hopeful thinking. Positive coping strategies were positively correlated with career identity. The final regression model showed that coping strategy and satisfaction with the participant’s major accounted for 37.6% of the variance in predictions of career identity, with problem-focused coping strategy as the single most influential factor. Conclusion: These findings suggest that a range of active efforts are needed to increase the use of problem-focused coping strategies to improve the career identity of nursing students.

Functional foods for health are often consumed among adolescents. To investigate functional food usage, this study surveyed 326 students aged 14-16. 56.3% of the subjects answered that they were interested in health. More than 76% of the subjects thought themselves to be very healthy. Users of functional foods made up 56.7%, and among all types of functional food, probiotic supplements were taken most frequently, followed by nutritional supplements>red ginseng products>enzyme containing products. Most users of functional food got the information on functional food through family (71.3%). 50.3% of users experienced the effectiveness of the functional food when they supplemented. After use, repurchase intent was 58.1%. In order to investigate the relationship between academic stress and functional food usage, groups were classified as stressful (n=124), intermediate (n=122), and low stress (n=84) according to self-perception about stress. There was no significant difference in the intake of functional foods according to academic stress. However, in the intermediate stress group, academic stress index was improved in the users of functional foods. In conclusion, the results of this study can be used to develop functional foods in the future, possibly helping to prepare nutrition education materials, reducing academic stress among adolescents with middle stress.

본 연구는 직무 특성 모델에서 제시한 다섯 가지 직무 특성 가운데 하나인 기술다양성이 외국인 투자기업 근로자들의 직무 스트레스에 미치는 영향에 대한 것이다. 직무 특성과 직무 스트레스에 대한 대부분의 기존 연구들은기술다양성이 증가할수록 근로자의 직무 스트레스가 줄어든다고 주장하였으나, 본 연구는 기술다양성이 근로자의직무 스트레스에 정(+)의 영향을 미칠 것이라고 주장하였다. 또한 경쟁 가치 모델에서 제시한 네 가지 조직문화가운데 관계지향 문화는 기술다양성과 직무 스트레스 간의 정(+)의 관계를 약화시키는 역할을 하고, 과업지향문화는 기술다양성과 직무 스트레스 간의 정(+)의 관계를 강화시키는 역할을 할 것이라고 주장하였다. 68개 외국인 투자기업에 재직 중인 1,989명의 근로자 자료를 활용하여 위계적 회귀분석을 통해 이상의 가설을 검정한결과, 기술다양성은 직무 스트레스에 정(+)의 영향을 미치는 것으로 나타났다. 또한 관계지향 문화의 조절효과는통계적으로 유의한 것으로 나타났으며, 과업지향 문화의 조절효과는 통계적으로 유의하지 않은 것으로 나타났다. 추가적으로 124개 로컬기업에 재직 중인 2,673명의 근로자 자료를 활용하여 외국인 투자기업과의 가설 검정 결과를 비교하였으며, 기술다양성과 직무 스트레스 간에 비선형 관계(U형 관계)가 존재하는지에 대해 살펴보았다.

The recent domestic construction market is in a difficult situation due to reduction of the government's SOC budget and new orders from public-sector, and the deterioration of housing supply situation in the private sector etc. In addition, the number of disasters in the construction industry has increased in recent years with 26,570 people (up 5.7% from the previous year) in 2016, unlike other industries that are in a declining trend. As such, the construction industry has unique characteristics and problems such as high industrial accidents rate, abnormal subcontracting structure, excessive working hours and work intensity. As a result, the construction workers have a lot of job stresses. Job stress has been recognized as one of the major causes of industrial accidents and many researches have been conducted on that. However, most of the researches were about the factors that induce job stress and how these factors affect disaster occurrence, job satisfaction, job performance, turnover intentions, and job exhaustion. The purpose of this study is to investigate the effect of positive psychological capital on job stress, which is emerging as a new human resources development paradigm useful in corporate management in order to find ways to reduce job stress. To do this, 347 data collected from construction workers in Daejeon, Sejong, and Chungcheong provinces were analyzed using statistical package(IBM SPSS 22) for basic statistical analysis, reliability analysis, and regression analysis. As a result, positive psychological capital has shown an alleviate effect on job stress. In particular, the higher the optimism, hope, and resiliency of positive psychological capital, the lower the job stress. However, the higher the self - efficacy, the higher the job stress.

Most people seek a happy life and happiness positively affects sentiment, satisfaction with life, creativity, human relationship, business productivity, and even health and life extension. However, according to a survey in 2013, subjective happiness of adolescents (including university students) was very low compared to other age groups in Korea. Therefore this paper examined the effects of job-seeking stress, appearance recognition, financial situation, trust in government, and locus of control on university students' happiness using SEM (structural equation modeling). 207 university students in Seoul, Korea have been surveyed. At first, an initial experimental SEM model among these variables has been set up and reliability analysis has been conducted. Then multiple regression analyses on job-seeking stress and happiness as well as SEM analysis have been conducted. As a result of these analyses, the SEM model has been revised two times. The final SEM model passed the goodness-of-fit test (using RMR, GFI, NFI, CFI, and IFI indices). The final SEM model showed the followings. First, Higher job-seeking stress (especially sentimental part, rather than environment or action related parts) negatively affects happiness. Second, Trust in government also affects happiness both directly and indirectly. Third, Locus of control is affected both by trust in government and financial situation. Fourth, appearance recognition heavily affects job-seeking stress. In addition, appearance importance is higher than appearance interest, meaning that students who are not very interested in appearance usually recognize the importance of appearance. Finally, happiness is affected neither financial situation nor appearance recognition. Therefore, even either they are in a poor financial situation or not happy with their appearance, they can be happy if they have firm locus of control.

본 연구에서는 어머니의 양육스트레스와 결혼만족도가 양육효능감 및 양육행동과 어떠한 관계가 있는가를 탐색하고자 하였다. 이를 위해 한국아동패널(7차) 자료를 활용하여 평균 72.12개월의 유아가 있는 1544명의 어머니를 대상으로 최종 분석하였다. 연구를 위해 첫째, 어머니의 양육스트레스, 결혼만족도와 양육효능감, 양육행동 간의 상관관계를 살펴보았으며, 둘째, 어머니의 양육스트레스와 결혼만족도가 양육효능감과 양육행동에 미치는 영향력에 대해 알아보았다. 연구 결과, 어머니의 양육스트레스와 결혼만족도는 양육효능감 및 양육행동과 각각 관련이 있으며, 어느 정도 예측력을 지니고 있는 것으로 나타났다. 특히 양육스트레스는 양육효능감 및 양육행동을 부적으로 의미 있게 예측하는 것으로 밝혀졌다. 이러한 연구 결과를 기초로 본 연구의 제한점과 시사점에 대해 논의하였다.

본 연구는 노동시장에 여성근로자가 활발히 진입하는 상황에서 객관적으로 보이는 조직문화와 조직특 성이 과연 남녀근로자의 조직몰입과 조직스트레스에 동일한 영향을 미치고 있는가에 대한 질문에서 출발 한다. 지금까지 조직의 여성친화성은 대체로 일-가정 양립 지원 정도에 국한되어 다루어져 왔으며, 이는 조직의 조직문화와 조직특성 자체가 근로자의 성별에 따라 상이한 영향을 미칠 수 있음을 간과한 것이다. 이러한 문제인식에서 본 연구는 조직문화를 경쟁가치모형에 기반한 1)집단지향문화, 2)혁신지향문화, 3) 시장지향문화, 4)위계지향문화로 구분하였다. 조직특성은 개인의 조직신뢰 정도와 인재관리로 구분하였 다. 이 후 조직문화와 조직특성이 성별과의 상호작용을 통해 근로자의 조직몰입과 조직스트레스에 어떤 방식으로 영향을 미치는지 규명하고자 하였다. 이를 위해 제6차 인적자본기업패널(HCCP) 자료를 활용하 여 분석을 시행하였다. 분석 결과 첫째, 남녀 근로자는 조직문화를 집단지향/시장지향/위계지향/혁신지향 순으로 동일하게 인지하고 있으나, 여성보다 남성의 하위문화 인식 정도가 일관되게 높았다. 그럼에도 위 계지향문화의 경우, 남녀 간 인식차가 거의 없어 동일조건에서 여성이 위계지향을 남성보다 더 강하게 느낌을 확인하였다. 둘째, 여성의 조직몰입이 남성보다 약한 것은 실제 성별의 차이가 아닌 조직문화와 성별 간 상호작용 효과에 의한 것으로 나타났다. 집단지향/시장지향문화가 조직몰입을 강화하는 듯 보였 으나, 성별과의 상호작용 분석 결과 남성근로자의 조직몰입은 강화하나, 여성근로자의 경우 약화시킴을 알 수 있었다. 종합해 볼 때, 객관적으로 보이는 조직문화 지향은 남녀근로자의 조직몰입과 조직스트레스 에 상이한 영향을 보여주고 있으며, 이는 여성근로자의 효과적 활용을 위해 조직문화 하위요소의 차별적 강화전략이 필요함을 시사한다.

The domestic construction market is in a difficult situation due to the recent decline in government SOC budgets, sluggish new orders from large public corporations, and deteriorating housing supply conditions in the private sector. In addition, construction workers compared to other industries have higher levels of job stress due to higher non-regular workers, unstable and irregular working hours, high work intensity, and poor work environment. According to previous research results, high job stress of construction workers has a great impact on the occurrence of disasters, and it is urgently needed to improve the job stress. The purpose of this study is to investigate the effect of Positive Psychological Capital such as positive self - efficacy, optimism, hope and resilience on job stress. Based on the results of this study, we suggest a plan to reduce job stress of construction industry workers.

본 연구는 열 스트레스 하에서 오리사료 내 대사에너지(ME) 수준이 오리의 간, 십이지장 융 모, 미생물, 유전자 조절에 미치는 영향을 조사하였다. 총 240마리의 육용 오리 채리밸리(Anas platyrhynchos)를 4처리구로 완전임의배치 한 후 42일 동안 사육하였다. 처리구는 ME 2900 kcal/kg, ME 3000 kcal/kg, ME 3100 kcal/kg 및 ME 3200 kcal/kg로 구분하였다. 간 조직은 처리구 사이의 차이가 없었고, 십이지장 융모 및 창자샘 길이는 ME 3000과 비교할 때 2900은 10.58% 감소하였으나 3100, 3200과의 사이에 차이는 없었다. 맹장 Latobacillus는 ME 3000과 비교할 때 2900은 9.47% 감 소하였으나 3100, 3200은 각각 2.52, 3.24% 증가하였다. Total aerobic bacteria, E. coli, Coliform bacteria는 ME 3000과 비교할 때 2900은 증가하였으나 3100, 3200은 차이가 나타나지 않았다. 간에서 HSP (heat shock proteins)-mRNA 중 HSP 90-α는 ME 3000과 비교할 때 2900은 48.60% 감소하였 으며 3100, 3200은 차이가 없거나 증가하였다.

The purpose of this study is to find and compare the differences in stress level, stressor, and coping style of high school students according to their personality traits. And to identify the personality traits contributing to stress reduction. The results of the study can be used as basic data for reducing the stress of adolescents to improve their academic achievement and maintain mental and physical stability. The questionnaire survey was conducted for 10 days from June 7 to June 16, 2017 for S high school students in Chungbuk Province. The study employed four measuring instruments as Ego-gram, Ok-gram, stressor scale, and stress coping type scale. Individual personality traits were classified into ego-states and ok-states in TA (Transactional Analysis). Stressors are classified into 5 categories (school life, home life, human relationship, myself, environment) and stress coping styles are classified into 4 categories (problem-focused coping, social-support coping, feeling-focused coping, hope-thinking coping) used in the previous studies. The collected data were analyzed using T-test, ANOVA, and multiple regression analysis. As a result, the stress level of high school students showed significant differences according to sex, year, grade, sleeping time, personality traits, and coping styles. Personality traits that contributed to the stress increase were NP, AC, ‘you positive’, ‘i negative’ and personality trait that contributes to stress reduction is ‘you negative.’ Therefore, we can judge that individual personality traits have significant effects on stress level, stressor, and coping style and need to find the effective stress management method suitable for individual personality traits using counseling, repetition training, self-suggestion etc.

The purpose of this study is to investigate the factors and effects of job stress of construction workers on construction accidents and turnover intention in order to improve the field work environment of construction industry which shows higher industrial accidents than other industries. To this end, research models and hypotheses were established based on previous research, and the questionnaire was distributed to 10 construction companies in Daejeon, Sejong, and Chungcheong provinces. The 301 data collected were performed statistical analysis such as basic statistical analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, and logistic regression analysis using the statistical package (IBM SPSS 22). The results of this study are summarized as follows. First, job stress has a significant effect on accident occurrence. Among the sub-factors of job stress, there was positive (+) influence on work culture and relationship conflict between peers, and organizational system had negative influence. Job demands, compensation incompetence, and job instability were not statistically significant. Therefore, it is necessary to concentrate on the factors of work culture, organizational system, and relationship conflict in the construction site. Second, job stress has positive effect on turnover intention. Job stress, inadequacy of compensation, and work culture were positively related to turnover intention. Third, job demands have a slightly greater impact than compensatory inadequacies. The factors that make the job turnover more important are the excessive job burdens such as respect, internal motivation, responsibility rather than expectation non-conformity, time pressure, increase of work load. Therefore, in order to reduce the turnover intention of the construction worker, it is necessary to pay attention to improvement of the job requirement. Fourth, the worker’s job stress could overcome by exercise and fatigue elimination, work environment management, and self-opening for others. It is necessary to establish a work environment management system for counseling and intimacy formation to open up the exercise and fatigue relief program of the workers at the construction site and to open themselves between the workers and the supervisors.
