최근 친환경 재료와 구조물에 대한 관심이 증대되면서 친환경 재료인 황토에 대한 연구가 활발히 진행되고 있다. 황토는 건설 및 마감 재료로 사용된 전통적인 친환경 건설 재료 중의 하나이다. 황토는 높은 축열성, 습도 조절 능력, 자정력, 탈취 및 항균성능, 인체에 유익한 다량의 원적외선이 방사되는 점 등 건설 재료로서 많은 장점을 갖고 있다. 그러나, 황토는 낮은 강도특성과 건조수축 균열 특성 때문에 현대 건설에 사용되지 않고 있는 실정이다. 최근 연구자들의 연구결과에 따르면, 황토는 플라이 애쉬나 포졸란 같은 천연 포졸란 재료로 사용될 수 있다. 본 논문에서는 황토와 슬래그, 재생 PET 섬유가 혼입된 콘크리트의 역학적 성질과 구조적인 휨 거동 실험을 수행하였다. 실험 결과 황토콘크리트의 압축강도와 탄성계수는 기준 시멘트 콘크리트 시편보다 상대적으로 낮게 평가되었으며, 철근 콘크리트 보의 휨 거동은 거의 유사하게 나타났다.

Ralstonia solanacearum에 의한 고추 풋마름병은 고추의 생산량 감소에 영향을 미치는 주요 병해 중 하나이다. 그리고 병 저항성 작물을 재배하는 것은 고추의 풋마름병 방제에 가장 효과적인 방제 방법이다. 본 연구는 고추의 풋마름병 저항성을 효율적으로 검정하기 위한 방법을 개발하기 위하여 수행되었다. 풋마름병에 대한 저항성 및 감수성 6개 고추 품종을 선발하고, 다양한 조건에서 이들 품종의 풋마름병 발생을 조사하였다. 접종 방법에 따른 고추 품종들의 풋마름병 발생 정도를 실험한 결과, 상처없이 토양관주하는 방법과 접종원에 뿌리를 침지하는 방법보다 뿌리 절단 후 접종원을 관주하는 방법이 더 간단하고 효율적이었다. 풋마름병 저항성 계통인 'MC4'는 파종 후 21일부터 28일 재배한 고추 유묘에 $1{\times}10^8cfu/ml$ 농도의 세균 현탁액을 포트 당 20 ml 접종하였을 때 가장 높은 저항성을 나타냈다. 한편 감수성 품종들은 이들 조건에서 높은 감수성을 보였다. 이들 결과는 우리가 고추 품종의 풋마름병에 대한 효율적인 저항성 검정방법을 개발하였다는 것을 나타낸다. 그리고 선발한 발병조건을 사용하여 시판중인 140개 고추 품종의 풋마름병에 대한 저항성 정도를 평가하였다.

The blueberry eco-friendly farming requires the soil condition of pH 4.2 ~ 5.2 and high in organic matters for stable growth. Most of soil types of blueberry-growing land in Korea, however, belongs to alkaline soils with low organic matter content. As a result, the eco-friendly blueberry growers use peat moss and sulfur powder heavily to improve the soil condition, but the guideline on the effective use of organic materials was not established yet. Therefore, this sturdy was performed to investigate the effect of increasing soil acidity and organic matters by using organic materials. Among 5 organic materials, the pH of soil was lowest in degradable sulfur + bentonite (pH 4.1) and followed by Peat moss+Chaff+Pine Needlesmixtures(pH 4.5), OrganicAcid +vinegar (pH 4.7), Sulfur powder (pH 4.8), Temperature response Elutioner (pH 5.2). The soil organic matter content were increased in the following order: Peat moss+Chaff+Pine Needlesmixtures (8.4%) > degradable sulfur + bentonite (7.8%) > Organic Acid + vinegar (7.2%) > Sulfur powder ${\fallingdotseq}$ Temperature response Elutioner (6.3%). Although different in the degree, all organic materials treated was recognized a good material for improving soil pH and organic matter content. The plant height and stem diameter of blueberry were no clear difference among 5 organic materials. Another study was carried out to investigate amending soils with organic matter by soil mulching with pine needles for soil surface management in blueberry organic cultivation. The effect of increasing the soil pH by pine needle mulching in blueberry eco-friendly farming was recognized in four test fields. Pine needle mulching for soil surface management in blueberry appeared several advantages, such as improving of soil pH and organic matter content. Therefore, pineneedle mulching in blueberry organic farming is considered as the most efficient means of mulching cultivation for amending soil pH, weed suppression and moisture conservation among mulching materials.

해양환경에 노출된 콘크리트는 육상에서 건설되는 콘크리트와 달리 해풍, 조력, 파도, 파랑 등에 의한 물리적 작용과 해수의 $SO_4{^{2-}}$, $Cl^-$ 및 $Mg^{2+}$ 이온 등에 의한 화학적 침식작용 및 동결융해 등 가혹한 환경에 노출되어 콘크리트의 내구성을 크게 저하시킨다. 해중 콘크리트의 대규모 시공은 콘크리트의 강도손실은 물론 알칼리(pH) 및 중금속 등 환경유해물질이 용출될 수 있어 이에 대한 충분한 검토와 연구가 필요한 실정이다. 본 연구에서는 전기로 환원슬래그로부터 CSA 자극제를 개발하고 전기로 산화슬래그를 콘크리트용 골재로 활용하여 인공리프용 친환경콘크리트를 개발하였다. 초기강도는 Normal concrete보다 낮게 나타나 친환경콘크리트의 초기강도 품질향상을 위한 추가적인 연구가 필요하였으며, 친환경콘크리트의 해수저항성은 양생일 1년 대비 평균 강도손실이 8~9% 발생하였다. 고함량 고로슬래그 미분말과 고비중 전기로 산화슬래그 골재를 사용한 친환경콘크리트를 동결융해저항성 재료로써 충분히 활용할 수 있는 가능성을 확인하였다. 친환경콘크리트의 중금속 용출특성은 콘크리트의 수화반응을 통한 경화과정에서 중금속 성분은 화학적 결합을 통해 고정화되기 때문에 환경유해성 기준 이하이거나 검출되지 않아 유해물질 용출에 안전하다는 것을 확인하였다.

Since artificial building materials and environmental contamination are getting worse recently, people has been interested in eco-friendly construction. In addition, the problems like Sick Building Syndrome are issued these days. In order to solve these problems, the reuse of building materials and the development of environment-friendly materials are urgently in demand. In this sense, Hwangtoh is in the limelight as the environment-friendly material, and broad studies on it have been in progress. However the reactivity of Hwangtoh is low, and without activation process it is very hard to use it as a building material. This study examined the usability of Hwangtoh as an environmental building material by experimenting the reactivity of inactivated Hwangtoh with Reaction Induction Material.

Interior material covering as the final process of house-building, critically influences not only aesthetic character but also air quality of indoor space. Wall covering today, however, caused a serious social problem because of chemicals contained in the industrial wallpaper and artificial glue. In this context, Korean traditional wall covering of Han-ji can be an alternative model due to it's ecological character. Recently 'Hanok' attracts public attention, since society and people become to appreciate the unique beauty and value of our traditional culture. The values include natural beauty, emotional character, and environment-friendliness. Recognizing this, this paper intended to scrutinize the operating process of Han-ji as an interior finish material. Historical research method was employed, tracing the related articles in old literature and interviewing with the witness of the experienced expert. Thereby, healthier and unique aesthetic indoor environment can be expected to be sustainable along with the rich cultural life of ancestors.

Rapid economic growth brought material affluence and convenience, but it also has caused a negative issue, such as environmental damage. Therefore, this research holds the purpose of grasping structural influencing relationship of environmental awareness of cook, which is taking an important role in food safety among workers in hotel restaurants with eco-friendly attitude and food safety pursuit behavior. To achieve the purpose, collected materials were tested for the fidelity, organic causation and control effect, using Structural Equation Modeling for frequency analysis, confirmatory factor analysis, credibility analysis and hypothesis testing with SPSS (V23.0) and AMOS (V21.0) programs. Environmental awareness of hotel cook has causation with eco-friendly attitude, and the attitude has meaningful causation with food safety pursuit behavior. That is, it proved that cooks are taking care of their job carefully from the pre-cooking stage while most of people ignore the storing stage. The result shows not only hotel's own training session, cook's level of consciousness on the food safety and they are working with high sense of responsibility. The limitation of this research is that it only conducted with cooks of deluxe hotels in Busan, and it could not include various variables about environmental awareness. Therefore, it is expected that the lacking contents to be dealt by a follow-up study.

The recent rising living standards, environment-friendly, well-being and health aspects of life in the basic gratification, as well as the desire for a pleasant environment emotionally environmentally friendly way of external space or industrial interest in the indoor environment, the manifestation. In particular, the biggest problem of the indoor environment has been emerged as a Sick House Syndrome indoor space that is provided to the building materials, and the impact on the domestic and the indoor environment, and clean the house in a health standards are specified as laws. The performance rating and the various materials to create environmentally-friendly standards for building materials. The more detail, Porous clay material, toxic substances released by applying the high humidity and the water itself, and to absorb the moisture, if the emissions, without a separate device, to maintain a comfortable indoor environment and at the same time, one of the causes of Sick House Syndrome breaking down harmful substances to absorb a comfortable indoor environment to maintain an environmentally-friendly building interior material studies. It is aimed at the development to multi-functional high performance eco-friendly construction materials, rather than through one feature performance, identify key features for national and international eco-friendly building materials can exert Water Vapour Adsorption raw, decomposed materials for the application and selection.
