Environmental condition can induce changes in early life-history traits in order to maximise the ecological fitness. Here I investigated how temperature change and variation in human aquatic activity/behaviour affect early life-history consequences in fish using a dynamic-state-dependent model. In this study, I developed a general fish's life-history model including three life-history states depend-ing on foraging activity, such as body mass, mass of reproductive tissue (i.e., gonadal development) and accumulated stress (i.e., cellular or physiological damage). I assumed the level of foraging activity maximises reproductive success-ultimately, fitness. The model predicts that growth rate, development of reproductive tissues and damage accumulation are greater in higher temperature whereas higher human aquatic activity rapidly reduced the growth rate and development of reproductive tissue and increased damage accumulation. While higher foraging activity in higher temperature is less affected by human aquatic activity, the foraging activity in lower temperature rapidly declined with human aquatic activity. Moreover, lower survival rate in higher temperature or human aquatic activity was independent on mortality rate due to human aquatic activity or mortality rate when foraging activity, respectively. However, the survival rate in lower temperature or human aquatic activity was dependent on these mortality rates. My findings suggest that including of early life-history traits in relation to climate-change and human aquatic activity on the analysis may improve conservation plan and health assessment in aquatic ecosystem.

Purpose: Climate change has various negative effects on human health, which has resulted in increased burden on the health care system. Nurses contribute significantly to assessing climate-related health risks and creating a healthy environment. This study aimed to evaluate the reliability and validity of the Korean version of the Climate, Health, and Nursing Tool (K-CHANT) to measure nurses' awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Methods: The 22 items of English CHANT were translated into Korean with forward-backward translation techniques. Internal consistency reliability, test-retest reliability, and construct validity using confirmatory factor analysis were performed using SPSS WIN (25.0) and AMOS (26.0). Survey data were collected from 220 master's, doctoral, and post-doctoral nursing students. Results: The K-CHANT consists of 20 items across 5 domains. Two items of the original CHANT were excluded because of low content validity index and standardized regression weights. The internal consistency reliability of the K-CHANT, assessed by Cronbach's α was .81, with an intraclass correlation coefficient of .66~.90. The five subscales model was validated by confirmatory factor analysis (SRMR < .08, RMSEA < .08, AGFI > .70, CFI > .70). Conclusion: The K-CHANT has satisfactory construct validity and reliability to measure nurses' awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Future research should examine nurses' perceptions and behaviors related to the health effects of climate change and develop an action plan to improve it.

In light of the world grappling with diverse environmental issues due to climate change, the prominence of the 'pre-cycling' movement has grown. This movement strives to curtail or eliminate waste generation even before product purchases, garnering more attention than conventional eco-friendly practices. Consequently, this study employs experiments to delve into effective message strategies for promoting pre-cycling behaviors, which serve as preventive measures against the escalating environmental challenges posed by worsening waste problems. This study investigated the effects of message framing and temporal distance on pre-cycling behavioral intention. In terms of message frame, suggestive messages increased pre-cycling behavioral intention more than coercive messages, and temporal distance had no direct effect on pre-cycling behavioral intention. Assertive messages were associated with higher pre-cycling behavioral intentions when the target was interpreted as near future and suggestive messages were interpreted as distant future. Although temporal distance did not directly affect pre-cycling behavioral intention, it positively influenced consumers' pro-environmental behavioral intention by reducing their antipathy toward assertive messages. The implications of this study extend to the realm of management, offering insights into steering consumer behavior in response to pro-environmental messages.

This paper studies the activities characteristics of the elderly aged 60-75 years old who can take care of themselves in the community public space, and puts forward the design principles of the community public space in the aging society. Using the methodology of experience design, through naturalistic observation, questionnaires, interviews and shadowing, the spatial and temporal characteristics of daily activities of the elderly are analyzed. In the community public space, the behavior of the elderly is essentially a social activity to get more attention and communication. This determines the needs, time, frequency and duration of activities of the elderly in community public space. In the community public space, the behavior of the elderly has the characteristics of long-term and regularity, and its behavior changes slightly with the space, the objective factors that affect the elderly are gender, age and climate. The subjective factors are lifestyle, family members and income level.

기후변화로 인하여 가뭄은 그 위험성이 점차 높아질 것으로 예상되고 있다. 잠재적 대규모 가뭄피해를 사전에 예방하기 위해서는 가뭄에 보다 효과적으로 대응하기 위한 방안을 마련하는 것이 필요하며, 국가적 수자원 관리를 넘어선 국민 전반이 가뭄 심각성을 인지하고 적합한 대응을 하도록 유도하는 것이 중요하다. 기상, 수문, 농업 등 가뭄 발생의 다양한 측면들을 표현한 여러 가뭄지수 및 정보가 이미 생산되고 있으므로, 이러한 정보를 국민에게 제공한다면 국민이 가뭄의 심각성을 인지하고 물 절약 등의 행동에 동참하도록 하거나 농민의 경우 사전에 대처 방안을 마련하도록 하는 등, 공급측면에서의 수자원 관리 뿐만 아니라 수요 측면에서의 대응도 가능하게 될 것이다. 하지만 현재 제공되는 가뭄지수 및 정보는 전문적 지식이 있는 의사결정자 및 연구자 등을 위한 것으로, 일반 시민이 이러한 정보를 통해 가뭄의 상황을 이해하고 해석하여 그에 따른 행동을 하기란 어려운 것이 사실이다. 따라서, 본 연구에서는 국내 가용한 가뭄지수 및 정보로부터 국민이 체감할 수 있으며, 적절한 행동을 하도록 설득할 수 있는 가뭄정보 생산 방안을 도출하고자 한다. 사회과학적 이론, 포커스그룹 인터뷰 및 설문조사를 통하여 국민의 가뭄정보에 대한 인지 및 이해 특성을 파악하고, 시민자문단을 통하여 직접적으로 국민에게 현재 가용한 가뭄정보를 제공하고 어떻게 바라보는지 분석함으로써, 국민이 체감 가능한 가뭄정보의 방향을 제안하였다. 또한 현재 가뭄에 대한 뉴스 등이 어떠한 방식으로 생산되고 유통되는지를 분석하여 이로부터 사회과학적 측면에서 국민을 설득하기 위한 보다 효과적 방안을 제시하였다. 결과적으로 국민이 가뭄의 상황을 인지하고, 국가적 차원의 가뭄 대응의 필요성을 이해하며, 물 절약 등의 행동을 하도록 설득하는 것이 가능하게 되어, 점차 심각해져가는 가뭄에 효과적으로 대응할 수 있을 것으로 판단된다.

This study aimed to provide the information on the thermal sensation and the amount of clothing worn of junior high school students in winter classroom the relation with their climate adaptability. Total usable questionnaires were obtained from 467 male and female students. The questionnaire included general characteristics, physical characteristics, self awareness of body shape, climate adaptability and subjective thermal sensation in winter classroom. The data were analyzed using SPSS Statistics 18.0 for frequency analysis, factor analysis, chi-square analysis, t-test and correlation analysis. The results were as follows. The average body type based on BMI was normal($20.1kg/m^2$ ). Females perceived their body type as thinner than males. They wore more (8.67 garment items compared to 8.14 for males). Only about 25% of students voted the thermal sensation to neutral(47% cool~very cold, 28% warm~very hot). Females were more sensitive to the cold, perceived less healthy, and wore more garments in the cold. Students felt colder in winter classroom when their cold adaptability was lower and they actively adjusted thermal insulation against the cold. It is recommended to suggest the guidelines for the proper indoor temperature and for the wear behavior in classroom in the perspectives of increasing the learning efficiency and improving the students' climate adaptability.

가뭄관리에서 가장 중요한 요소는 1) 강수량, 지표수, 지하수, 댐수, 토양수분 등 물 공급량의 시 공간적 모니터링과 2) 이용가능한 물 공급량 약화 정도에 따라 적시적소에 물 이용자가 취해야할 행동요령을 제시하는 것이다. 가뭄지수는 가뭄관리에서 종합적인 물 공급량 정보를 하나의 수치로 정량화하여 가용 수자원의 악화정도를 나타내어 가뭄경보의 기준으로 활용된다. 현재까지 개발된 대표적인 가뭄지수들은 PDSI(Palmer Drought Severity Index), SPI(Standardized Precipitation Index), SWSI(Surface Water Supply Index) 등이 있다. PDSI는 여러 가지 제한점을 가지고 있지만 가뭄지수 개발의 시발점이 되었다는 점에서 전세계적으로 이용하고 있고 국내에서도 기상청의 공식적인 가뭄지수로 발표되고 있다. PDSI는 복잡한 물수지 모형에 의해 산정되며, 이용되는 매개변수는 지역의 기후상황, 보정자료기간 등에 민감하게 작용하고 있으나 이들에 대한 국내기후 환경에서의 평가가 선행되어 있지 않고 있다. PDSI는 가뭄과 습윤 기간의 시작과 종료 시점을 확률적으로 산정하여 이를 기반으로 가뭄경보에 활용하고 있다. 또한, 이들 확률은 기상학적 가뭄상황을 나타내는 PDSI에 후행하는 하천유출, 저수지 수위, 지하수 등의 수문학적 가뭄을 표현하는 PHDI(Palmer Hydrological Drought Index)를 산정하는 데 이용된다. Z-지수 역시 PDSI에서 얻을 수 있는 가뭄지수로 단기간의 가뭄특성에 의한 농업가뭄을 표현하는 데 적합한 지수로 알려져 있다. 본 연구에서는 PDSI의 제한점들을 살펴보고 우리나라의 기후상황, 자료보정기간 등에 따른 PDSI의 제매개변수들을 재산정하여 계산된 PDSI의 변동성을 검토한 후 이를 Palmer(1965)가 제시한 PDSI 산정식과 비교 평가하였다. 또한 가뭄의 시작과 종료 확률 개념에 의하여 산정된 PDSI를 기상청에서 제공하고 있는 PDSI와 비교 분석하여 개선점을 도출하였다.

Republic of Korea officially announced its mid term reduction target which reduce about 30% of BAU GHG emission by 2020 in the 15th meeting of UNFCCC(COP 15) held in Copenhagen, Denmark 2009. To achieve this goal, it is necessary to understand the serious of climate change and take part in GHG reduction not only industry but also the nation. However, such positive participation in green life which may cause inconvenient of the life of the people. It should be accomplished with providing reliable information. This study suggests the scientific potentialities of GHG emission by guideline on low carbon life and green life to form and change a lifestyle suitable for coping with climate change. And also, this study quantitate the GHG reduction which may reduce demand for air conditioning by cool biz and warm biz. In Korea, this campaign has become known as 'CoolMaebsi' by Ministry of Environmental of Korea. 'CoolMaebsi' is a compound word of 'Cool' which means feel refreshed, and 'Maebsi' is a Korean word which means attire. Though this campaign is effective and significant to reduce the GHG emission yet there were no study on quantitative analysis. Therefore this study calculated reduced energy consumption and potential GHG emission by measuring variation of skin temperature. As the result, wearing warm biz and cool biz have an effect of reducing not only the energy consumption but also GHG emission. To achieve the low carbon society, it is necessary to improve the energy saving system and introduce the policy which guide to change a life style.
