최근 실내 공기질(IAQ; indoor air quality)을 악화시키는 물질 중 하나인 이산화탄소 저감 연구가 다수 진행되고 있다. 현재 이산화탄소를 저감하는 방법에는 흡착법, 흡수법, 막분리법 등이 있다. 그 중 흡수법은 액체 상태의 흡수제를 분사하는 공정 특성상 실내에 적용하기 어렵고 2차 오염물 또는 폐수가 발생할 수 있다. 또한, 막분리법은 이산화탄소 분리를 위한 응집 및 침전과 같은 전처리 과정이 필요하므로 실내 이산화탄소 저감에 적합하지 않다. 반면, 흡착법은 비교적 저렴하고 운영이 간단하여 적용 사례가 증가하였으며, 유동 인구가 많고 환기가 어려운 지하철, 버스 등의 대중교통 차량 내부 및 교실, 사무실, 공공시설에서 배출되는 실내 이산화탄소를 제어할 수 있다는 장점이 있어 가장 적합한 해결책으로 알려져 있다. 흡착 공정에 사용되는 대표적인 흡착제 종류에는 활성탄, 제올라이트, 알루미나 등이 있으며, 이 흡착제들을 개질 및 성형하여 흡착제의 성능 및 기계적 강도를 증진시키는 고도화 연구가 활발히 수행되고 있다. 이처럼 적용 대상 내 설치 및 교체가 용이하도록 하는 흡착제 제조 기술 개발이 필요한 실정이며, 흡착제를 상용화 수준까지 발전시킴으로써 강화된 실내 공기질 규제 기준에 대한 대응 및 삶의 질 향상이 기대된다.

Design is objective and universal human aesthetic activity. Design originally began with the purpose 'to make public's life abundant and increase their quality of living." However, design education has bee developed to foster human resource to maximize production of company in the name of 'important production method for company.' Therefore, common people has been had many opportunities to learn about design. General people could not be satisfied their demand to learn about design due to narrow opportunities. Public has had resistance feeling for design that it has been exclusively occupied by certain designers. Therefore, it is urgent to expand the object of design education and change the contents which have been focused on fostering design professionals. This research examined about the goal of public design education (self-expression, enjoying quality of life, culture, and wisdom of living) as a way to increase our life quality by recognizing the need of public design education based on various social phenomena which strongly shows people's desire to pursue aesthetic life.

This study examines the effect of consumption level on the life satisfaction of baby-boom generation and further examines the mediating effect of subjective expectation(standard of living and government policy). This research uses the panel survey to explore ageing society in 2012 made by Korean Labor Institute, which studied 1,756(born in 1955~1961). SPSS 21.0 Package was applied to analyze the date and multi-regression analysis was conducted. As a result, first, the findings show that as the consumption level increases, the life satisfaction of the baby-boom generation goes up. Second, the findings reveal that subjective expectation partially mediates the influences of consumption level on the life satisfaction of baby-boom generation. This study further discusses the theoretical and political implication of the direction properties on baby-boomer based upon the results of the study.

The purpose of this study is to examine the effects of household income types and sources on the depressions and self-respect of the old aged. Although household income types and sources are supposed to be important to the mental health of the old aged as well as income level, there have been little policy interests to them. This study analyze the relationship between the household income types & sources and the mental health of the old aged, using the 8th data from the Korean Welfare Panel Study. Major findings are as follows. First, we find that there are considerable variations in the household income sources composition among the old aged, and that types of household income are related to the individual and family features of the old aged. Second, the results of regression analyses show that the household income types are associated with the depression and self-respect of the old aged. And, we find that some income sources affects the mental health of the old aged. The results of this study suggest that there should be policy attentions to the mental health effects of the household income sources so as to increase the adequacy of the income security system for the aged in Korea.

This study evaluated the dietary habits and health behaviors of Korean adolescents according to their nutrition label utilization. This study was conducted on the adolescents aged between 12 and 18 who participated in the 2016-2018 National Health and Nutrition Examination Survey. Subjects were classified into nutrition label utilizing group and non-utilizing group. Then the general information, diet habit and nutrient intakes, health status and obesity and mental health of the two groups were analyzed. There was no significant difference in skipping breakfast, frequency of eating out, smoking status and alcohol drinking status according to the utilization of nutrition labels. Nutrition label utilizing group had higher % KDRI of protein(p<0.05), calcium (p<0.01), phosphorus(p<0.01) and potassium intakes(p<0.01) than non-utilizing group. Nutrition label utilizing group had higher EQ-5D score(0.97) than non-utilizing group(p<0.001). Practical nutrition education using nutrition label is needed. So these results can be useful for supporting dietary education regarding use of nutrition label for adolescents.

본 논문의 목적은 우리들의 현실적 노면표지 형태가 그 강도, 종류 및 출현빈도 측면에서 드러내는 지속적 증대 내지 강화 경향성을 문제점으로 제기하면서, 이런 노면표지 형태와 운전행동 간의 관련성에 대한 심리학적 제반 이론들을 고찰해보고 아울러 여기서 상호 연관적 특성을 밝혀주는 하나의 적절한 모델을 개발해보고자 하는 데에 두었다 이 모델에서는 운전자의 사고예방이나 안전운행이 곡 필요한 수준의 노면표지 자극화(stimulation)를 통해 조성된 쾌적한 교통환경에서 보다 용이하게 가능하다는 점이 전제되고 있다. 우리가 인간행동을 총체적으로나 효과적으로 분석하는 데 있어서는 일반심리적이거나 행동주의적 제반 이론 관점이 다소 미흡하다는 점이 지적되었다. 반면에 보다 거시적이고 종합적인 통찰에 중점을 두고있는 형태주의 심리학이나 장 이론적 시각은 행동분석 시에 비교적 결실적인 것으로 밝혀졌다 노면표지 자극의 양상여하가 운전자에게 스트레스, 정보과부담, 과도한 심리적 각성상태 등으로 인해 부정적인 영향을 미친다는 점에서는 이런 문제점이 환경심리학적 고찰측면에서도 관심의 대상이 되고 있다. \"노면표지 조성화 양 관점 모델\"에서 시사되고 는 터이지만. 이 모델에서의 노면표지 형태가 이론적인 면에서 \"정서-인지적\" 인간관에 근거를 두고있어 궁극적으로 이것이 옳다면, 그것은 곡 필요한 최소한의 수준에 머물러야 한다는 것이다. 올바른 운전행동, 다시 말해 교통법규 준수 행동은 노면표지 양상 측면의 각종 자극적 강화대책보다도 오히려 실효성 있는 교통교육, 확실한 적발 단속과 엄중한 처벌대책에 상대적으로 훨씬 더 큰 비중을 두고있는, 바로 그런 운전자의 의식개혁을 통해 비로소 제대로 정착될 수 있기 때문이다. 이 모델의 타당성 여부는 후속적 실증연구를 통해 해명되어질 수 있을 것이다.
