민간경비가 치안의 한 축으로써 사회질서유지라는 본래의 목적을 달성하기 위해서는 전(全)사회가 동의하는 방향으로 나아가야하고, 그렇게 되기 위해서는 민간경비가 근거하는 철학적 가치와 이념적 기반이 조성되어야 한다. 이러한과정에서 민간경비가 지켜야 할 가치 또는 방향, 규범이 민간경비이념이다. 이러한 관점에서 이 연구에서는 민간경비가추구하는 진정한 규범적 당위론적 이념을 정립하는데 목적이 있다. 민간경비의 이념으로는 공공성, 공익, 능률성, 합법성, 대응성 등을 들 수 있다. 이들 이념들 간에는 가치충돌이 발생하기도 하지만, 상호 보완적인 조화를 이루어야 한다.

Characteristics of Color Differences of Rainbow-Colored Veneers by Fading Test
서진석,박상범,김종인,박령재,조영희 한국가구학회 2015 한국가구학회지 Vol.26 No.4
Natural dyeing is considered to be an alternative to chemical staining in terms of harmful VOC-free and environmentally-friendly ingredient. This study was concerned with an evaluation of color performance of naturally dyed- and painted veneer for cylindrical laminated veneer lumber etc. according to the used condition in terms of existence of light and heat in drying. From the results, the color changes by the color of dyed veneer and the type of paint are likely to be affected by fading condition of light or heat. In the future, long-term outdoor exposure test needs to be additionally followed in order to evaluate durable usability of colored veneers.

In order to evaluate a feasibility of industrial art use of veneer such as cylindrical laminated veneer lumber, the veneers of 4 species of Korean pine, radiata pine, yellow poplar and Japanese cypress were natural dye-colored and clear finished. Natural dyes were red color originated from sappanwood, blue color from polygonum indigo, and yellow color from Amur cork tree and gardenia. the clear coats of crack seal clear and UV protection oil were applied on the dyed veneer. The dyeing and finishing characteristics through fading test were summarized as follows; In non-dyed and non-finished Korean pine veneer, lightness was decreased and yellow and red hues increased after fading test. In natural dyed- and finished- veneer, color difference of gardenia-mixed Amur cork tree was generally highest, and that of polygonum indigo was lowest. Compared to non-treatment of veneers of Korean pine and yellow poplar, color difference decreasing effect by finishing was shown in crack seal clear and UV protection oil. In addition, UV protection oil was more favorable than crack seal clear with more decreased color difference. In result, maximum values of color difference after fading for 8 days were recorded about 16 to 20, which are remarked ‘very much’ of 12.1 or more when reviewing with ‘National bureau of standards unit in USA’.
