이 연구는 지난 20여 년 동안 우리나라 환경교육의 활성화를 위하여 많은 연구자, 학교 교사, 환경단체 지도자가 제안해 온 과업을 다루고있다. 그것은 학교 안팎에 걸쳐 요람에서 무덤까지 환경교육이 체계적이고 지속적으로 이루어질 수 있도록 법적, 제도적 기반을 마련하는 것이다. 법제적 뒷받침이 환경교육의 활성화를 위한 충분조건은 되지 못하더라도 필요조건으로서 매우 중요한 의미를 갖고 있다는 점은 분명하다. 이 연구를 수행한 사단법인 한국환경교육학회는 국회환경포럼과 함께 환경교육진흥법(가칭) 시안의 개발과, 나아가 실질적인 입법화를 위해 노력하였다. 이를 위하여 먼저 우리나라에 이미 존재하는 도서벽지 교육진흥법, 특수교육진흥법, 산업교육진흥법, 영재교육진흥법, 과학교육진흥법, 유아교육진흥법, 이상 여섯 개의 교육진흥법을 분석하여 환경교육진흥법 시안 개발을 위한 시사점을 얻고자 하였다. 다음으로 외국의 환경교육 관련법에 대한 사례 연구를 진행하였다. 특히 미국의 경우 1970년 처음 환경교육법이 제정된 이후 몇 차례의 개정과 재승인 과정을 거쳐왔다. 미국에서는 1990년에 제정된 국가환경교육법의 재승인에 관한 공청회가 지난 2000년 여름 동안 개최되어 환경교육법의 필요성, 효과, 고려할 조항 등 본 연구에 중요한 참고 자료를 얻을 수 있었다. 본 학회의 다른 연구진에 의해 2001년 10월에 완료된 제2차 환경교육 중 ·장기 강화방안 연구의 결과물도 환경교육 활성화를 위한 시안에 담아야 할 내용과 방향을 결정하는데 실질적인 도움을 주었으며, 이를 토대로 연구진과 국회환경포럼의 환경교육활성화위원회의 위원이 윤독과 수정을 거쳐 시안의 타당성과 완성도를 높이고자 하였다. 작성된 시안에 대해서는 먼저 국내의 환경 또는 환경교육 관련 전문가에게 설문지를 보내어 의견 수렴을 하였으며, 이 과정에서 시안에 포함된 대부분의 항목에 대해 높은 찬성률을 보인 것으로 나타났다. 그밖에 설문지로부터 수정 ·보완 요청 사항을 정리하여 최종 시안을 작성하는데 반영하였다. 끝으로 10월 26일 국회 의원회관에서 개최된 공청회를 통하여 다양한 집단의 의견을 수렴하였으며, 공청회 동안 제시된 의견들을 반영하여 최종 시안을 작성하였다. 이러한 과정을 거쳐 작성된 환경교육진흥법 최종 시안은, 제1조 목적에서 제11조 환경교육연구의 진흥에 이르기까지 총11조로 구성되었으며, 환경교육사 자격증제 및 환경교육 프로그램 인증제 등 획기적인 전기를 마련할 수 있는 방안들이 다수 포함되어 있다. 특히 환경교육진흥법의 주무 부처를 환경부로 제안한 것은 기존의 교육 관련 진흥법들이 교육인적자원부를 주무로 하고 있는 것에 비해 매우 특기할 만 하다. 그 이유는 본문에서 밝힌 바와 같이 환경교육이 갖고 있는 특수성 때문이다. 환경교육진흥법의 주무 부처를 환경부와 교육인적자원부 중 어디로 하는 것이 바람직한가에 대해서는 연구진 내부는 물론 공청회에 참가한 사람들 사이에도 이견이 있었음을 밝혀 둔다. 끝으로, 이 연구에서 마련된 시안과 연구 결과가 최종적으로 속히 법제화가 되고, 우리나라 환경교육 진흥에 기여하게 되기를 바란다.

최근, 유한한 에너지 자원의 한계와 지구 온난화 등으로 세계의 제조 산업은 새로운 국면을 맞이하고 있으며, 특히, 자동차 산업은 화석연료를 주 에너지원으로 사용한다는 점과 이 연료를 연소시킬 때 발생하는 이산화탄소가 지구 온난화의 주된 원인이 될 수 있다는 점에서 상기 문제들을 해결하기 위한 다양한 방법에 주목하고 있다. 그 중에서 자동차의 생산기술 측면에서 볼 때, 가장 중요한 이슈는 차체 경량화다. 자동차 차체는 자동차를 구성하고 있는 여러 가지 부품 중에서 약 40% 정도의 무게 비율을 차지하고 있기 때문에, 차체 경량화는 연비향상과 이산화탄소 배출가스 감소와 직접적인 관계를 가지고 있다. 다양한 차체 경량화 방법 중에서 가장 쉽게 접근할 수 있는 방법이 경량소재 적용에 의한 경량화 방법이다. 현재, 탄소섬유 강화 플라스틱과 같이 무게 절감 비율을 최대화 할 수 있는 소재들도 개발되어 일부 적용되고 있지만, 일반적으로 차체 경량화 소재로 가장 널리 사용되고 있는 소재는 알루미늄 합금이며, 이에 대한 차체 적용 비율이 점차로 높아지는 추세에 있다. 이에, 본 연구에서는 알루미늄 합금이 차체에 적용되었을 때의 장단점을 살펴보고, 알루미늄 합금을 적용한 차체 생산과정에서 유의해야 될 사항들과 이를 바탕으로 하는 생산성 극대화 방안에 대하여 고찰하였다. 먼저, 기존의 알루미늄 저항 점 용접공법의 단점을 최소화하고 대량생산 체계에 적합하도록 개발된 새로운 개념의 저항 점 용접 시스템에 대해 그 성능과 양산성을 검증하였다. 구리 전극과 알루미늄 피용접물 사이에 프로세스 테이프를 삽입하여 용접하는 이 시스템은 열전도성이 큰 알루미늄 용접부에서 저전류의 조건에서도 효과적으로 균일한 발열현상이 발생하게 하였으며, 전극 팁 드레싱 없이 모든 용접점이 항상 동일한 조건에서 용접이 이루어질 수 있도록 하였다. 용접 조건 설정에 있어서도 용접전류가 통전되는 순간에 전극 가압력을 자유로이 변형시켜 용접부 크랙 발생을 최소화할 수 있음을 확인하였다. 알루미늄의 또 다른 대표적인 접합방법인 아크용접에 있어서는 용접 입열량을 조절하여 용접변형을 최소화 할 수 있는 아크용접 시스템에 대해 양산성과 적용 타당성을 검토하였다. 와이어 송급 방향을 자유자재로 바꿀 수 있는 이 시스템의 특성에 의해 스패터를 최소화하면서 용융금속이 효과적으로 모재에 금속이행 될 수 있음을 확인하였으며, 판재, 압출재, 및 다이캐스팅재 등 다양한 차체 소재에 대한 용접 가능성 및 미그-레이저 하이브리드 용접과의 비교분석을 통하여 차체 박판 용접에서도 최소의 열변형으로 효과적으로 사용될 수 있음을 보였다.

A girder height limitation is the critical parameter for rapid construction of bridge deck and construction space limitation especially in urban area such as high population area and high density habitats. A standard post-tensioned I-shaped concrete girder usually demands relatively higher girder height in order to retain sufficient moment arm between compression force and tensile force. To elaborate this issue, a small U-shaped section with wide flanges can be used as a possible replacement of I-shaped standard girder. This prestressed concrete box girder allows more flexible girder height adjustment rather than standard I-shaped post-tensioned girder plus additional torsion resistance benefits of closed section. A 30m-long, 1.7m-high and 3.63m-wide actual small prestressed concrete box girder is designed and a laboratory test for its static behaviors by applying 6,200kN amount of load in the form of 4-point bending test was performed. The load-deflection curve and crack patterns at different loading stage are recorded. In addition, to extracting the dynamic characteristics such as natural frequency and damping ratio of this girder, several excitation tests with artificial mechanical exciter with un-symmetric mass are carried out using operational frequency sweep-up. Nonlinear finite element analysis of this 4 point bending test under monotonic static load is investigated and discussed with aids of concrete damaged plasticity formulation using ABAQUS program.

These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

Over 200,000 Korean cultural heritage items are currently located abroad. They have made their way to 22 countries under different circumstances and with unique backgrounds. While some of them continue to contribute to promoting Korean culture around the world, others cannot be exhibited due to damage or poor condition. In view of these circumstances, the Overseas Korean Cultural Heritage Foundation (OKCHF) has since 2013 provided museums and art galleries abroad with support for the conservation, restoration, and utilization of the Korean cultural heritage items that they house. As a part of these efforts and on the occasion of the 120th anniversary of the diplomatic relationship between the Republic of Korea and the Kingdom of Belgium in 2021, a gilt-bronze case for acupuncture needles dating to the Goryeo period (918-1392) from the collection of the Royal Museums of Art and History (RMAH), Belgium was brought to Korea for conservation treatment. The primary purpose of this conservation treatment was to restore the original form of the relic and slow to the degree possible the progress of corrosion. The conservation treatment of the gilt-bronze case followed the fundamental order of conservation treatment: removal of corrosive substances, stabilization, and reinforcement. Since this was the first case of restoring metallic cultural properties under the abovementioned support program by the OKCHF, special methodologies distinct from those available in overseas institutions were required. Diverse scientific methods (e.g., X-ray inspection, CT scanning, 3D microscopy) were applied to identify the metalcraft techniques used in the Goryeo period. The analysis found that several designs, including lotus and scrollwork, were exquisitely engraved on the surface of the case by making dots using a round-edged chisel. A bronze plate engraved with designs was rolled into a cylindrical form. The ends were overlapped by 2 to 3 centimeters and then attached to each other by silver soldering. The overlapping ends were welded flat with nearly no gaps. As the final process in the production, the case was lavishly gilt with gold powder using amalgam gilding. The conservation treatment of the gilt-bronze case for acupunctural needles in the RMAH collection restored the original form of the relic and arrested further corrosion. Above all, it revived the historic and academic value of the overseas Korean cultural heritage through scientific analysis.

Security Act has been partially revised many times since it was revised to "Security Service Act". Main contents of such revision consist of the addition of security work such as protection or special security, responsibility enforcement of security company or security guard and systematic management of security service based on security work of previous security service act. But, it needs to be checked out that the fundamental matter about the concept of 'security' is directly related as double-edged sword in such flow of legal revision. That is because security service satisfies the multiple needs for security in the modern risky society and is based on the concept of active management whose goal is to forster and develop the function of actual security service comparing that current "Security Service Act" regulates the formal security service whose goal is permission of security service and systematic management based on article 2 as previous facilities and manned security that is guard duty-centered security service in another respect. So, this study pointed out the limit of interpreting security and security service in "Security Services Industry Act" in respect of providing private security service and drew the conclusion that the legislation and efforts are required for 'security for citizen' by reinterpreting the legislation and revision of private security service-related law as the normal regulation of "Security Services Industry Act" and the special law of "Private Security Services Industry Act".

Cylindrical laminated veneer lumber (LVL) is produced by winding the veneer tape on a circular cylinder. The veneer tape was produced by cutting the veneer into a rectangular shape and sewing it in a vertical direction to the fiber. The tensile strength test was carried out by producing the veneer tape specimen with different species of veneer, types and combinations of sewing yarn. The Radiata pine veneer tape produced with three sewing lines using the reinforced sewing thread had the best tensile strength. Also, the separation and snapping problems of the veneer tape were improved, resulting in the improvement in the workability of cylindrical LVL. The bending strength of various cylindrical LVL produced with different types of veneer tape and a different number of lamination layers and the application of reinforcement with glass fiber cloth was compared with that of Larix log. Bending MOR of cylindrical LVL reinforced with glass fiber cloth at the volume ratio of 11% was improved by 65% in comparison to the non-reinforced cylindrical LVL. In the case of the cylindrical LVL produced with 2 sewing lines of veneer tape, a fracture occurred at the butt joint between the veneer tapes. However, in the case of the cylindrical LVL produced with 3 sewing lines of veneer tape a fracture occurred in the fiber direction.

In this study, the management polices of micropollutants (MPs) were reviewed and the future management strategy was discussed considering climate change and etc. In Korea, the investigation of drinking water has been actively carried out for the priority contaminants as well as MPs. Recently river and lake waters have been also examined for MPs. However, the coverage and depth of the investigation is limited. Moreover, climate change is likely to increase air & water temperature and it will affect the hydrological cycle. Such changes may increase the residual concentrations of MPs in water system. As water reuse increases, the residual MPs of the recycled water may create public concerns. Thus, in a viewpoint of the precautionary principle, more stringent management of MPs is recommended for the drinking water and the body-contact water use. For the surface water, more studies are necessary to understand the ecological risk by MPs.

As the social demands for environmental pollution increase and regulations on the dyeing process wastewater are strengthened, supercritical dyeing process has been attracting attention as an alternative technology to reduce wastewater and energy consumption. In the supercritical dyeing process where carbon dioxide is used as a solvent instead of water as a solvent, there is no wastewater generated. The unfixed dyes can be reused later which makes the process environment-friendly. Also, after dyeing process, dried textiles can be obtained without additional drying process, which makes the process energy efficient. In this article, we have summarized the development of the supercritical dyeing process along with the research in Korea today and compared the principle of supercritical dyeing process with conventional dyeing process. To further explain the principle, studies of the distribution factor and mass transfer of dyes in supercritical carbon dioxide and fibers, as well as solubility between supercritical $CO_2$ and dyes are discussed. The dynamic behavior of dyes in supercritical dyeing apparatus and summary of the supercritical dyeing facilities developed around the world are also discussed. Finally, we suggest the direction of research and development for optimization of supercritical dyeing process and application to synthetic fibers and natural fibers except for polyester.
