In this study, the dietary fiber content of 33 kinds of agricultural products and seaweeds was compared with that of raw products after heat treatment. To verify the total dietary fiber analysis method, the recovery rate was reviewed by measuring the total dietary fiber content for 4 standard certified substances. As a result, the recovery rate of the analysis value for the true value was 98.8%~103.1%, which was judged to be reliable. The total dietary fiber of vegetables ranged between 0.61~5.36 g/100 g for raw vegetables and 0.55~4.84 g/100 g for heat-treated vegetables. Among the 24 kinds of vegetables used in the analanalysis, the total dietary fiber content of heat-treated Korean radish (3.13 g/100 g) was the highest compared to that of raw radish (0.61 g/100 g). The total dietary fiber of beans was between 13.86~29.69 g/100 g for raw beans and 6.72~18.40 g/100 g for heat-treated beans. In particular, the total dietary fiber content of sword beans was the highest in both raw (29.69 g/100 g) and boiled (18.40 g/100 g) beans. The total dietary fiber content of the three types of seaweed was 1.93~4.85 g/100 g in raw seaweed and 0.99~5.72 g/100 g in heat-treated seaweed.

Printing ink is faced various shear stress situation until it transfer to the printed substrate through the press. And in each shear stress condition the ink is needed to keep the appropriate viscosity according to the condition. The change of printing ink viscosity has been explained by well-known through the viscosity profile curve. But actually, the quality of printed paper depends on the ink behavior after transfer the substrates. Like this, to look into the behaviour of the ink on the printed substrate, it is needed the experiment of the ink structure recovering by rheology study. In this study, by controling the $CaCO_3$ content in the ink, after investigating the effect of the ink's structure recovery of the pigment concentration, we intend to predict the printing quality of the ink behvior on the substrate depending on pigment content.

This study presents a comprehensive solution to the collection management, which is based on the model for Cultural Objects (CCO). The developed system manages and spreads the collections that are safeguarded in museums and galleries more easily by using IT. In particular, we present our approach for a non-structured search and recovery of the objects based on the annotation of artwork images. In this methodology, we have introduced a faceted search used as a framework for multi-classification and for exploring/browsing complex information bases in a guided, yet unconstrained way, through a visual interface.

The degree of iron recovery from dust agglomerates was investigated experimentally to determine the optimum mixing ratio of coke in cold bonded pellet(CBP) which is fed into electric arc furnace(EAE) in the minimill plant. From the XRD analysis for EAF dust, magnetite(Fe$_3$O$_4$) and franklinite(ZnFe$_2$O$_4$) was identified as major components. Maximum iron recovery was obtained for the solid carbon content of approximately 18 weight percent. From plant trials of CBP composed of this optimal mixing condition, it was observed that electric power consumption and sulfur content increased with increasing the quantity of CBP.

Under the new environmental regulations announced by the government, utilities will have to cut their sulfur dioxide emissions by 60% from 1991 levels by the year of 1999. Sulfur dioxide emissions can be reduced prior to combustion by physical, chemical or biological coal cleaning. The new technology of high gradient magnetic separation (HGMS) offers the potential of economic separatoins of a variety of fine, weakly magnetic minerals including inorganic sulfur and many ash-forming minerals from coals. In the present paper, magnetic separation tests have been conducted on Korean anthracite and high-sulfur Chinese coal to investigate the feasibility of these techniques for reducing sulfur content from coals. In wet magnetic separation, the studied operating parameters include particle size, pH, matrix types, feed solids content, feed rate, number of cleaning stages and etc. The results shows that for wet separation, 60~70% of total sulfur was removed from coals with over 80% combustible recovery, on the other hand, for dry separation, 47.6% of total sulfur was removed from coals with 75% recovery.

Over seven years, BTS have organically embedded consistent mental health messaging and modelling of various mental health modalities, representing innovation within mental health discourse, within and outside the pop and K-pop culture and fandom. Their personal and artistic journeys have resulted in songs, imagery, and relationship dynamics within the group and within and between their fans ARMY, that organically model behaviours associated with mental health therapeutic modalities and normalize the discussion of mental health and well-being. This practice is vitally important in the effort to end stigma and encourage mental health well-being and recovery. BTS's authenticity establishes empathy with their audience ARMY and increases their ability to deliver these messages effectively. This includes fostering the creation of a peer support community within the group that extends to their fanbase ARMY, and from which fan-created mental health programs have emerged. BTS's innovation will be explored by examining content creation throughout their career, illustrating their consistent and organic messaging, culminating in overt and conscious mental health content in their latest album BE, which was released three weeks after the initial paper was presented, and provides proof of concept.

This study is about the recycling technology of scrap a PCB(printed circuit board) produced in home appliances or automobile industry. And we develop the recycling technology of cooper (Cu)which is contained to leaching solution. In stead of electrolytic collecting in existing sulphuric atmosphere, we apply process using the ammonia solution which is used in economizing energy. So m the process of electrolyzing scrap a PCB through the leaching and separation, we examine the effect of the nickel contained to the solution and the cooper degree of purity which is changed according to current density.

본 연구는 하수슬러지 소각재에 비교적 높은 함량으로 존재하는 인을 회수하기 위한 국내외 사례를 조사한 문헌연구로서 습식방법 및 열화학적 방법에 의한 인의 회수 및 중금속 제거와 관련한 실험조건과 영향인자 등을 논의하였다. 하수슬러지 소각재의 인 회수 기술 상용화를 위해서는 인 회수과정에서 발생되는 폐수, 잔재물의 처분, 첨가 약품과 에너지 소모의 최소화 등 전체 시스템의 경제성 측면에서 소각시설과 연계한 집적처리공정이 바람직할 것으로 판단된다.

폴리(디메틸 실록산)(PDMS) 성분을 포함하는 폴리우레탄(PU-Si)을 합성하고 이들의 열적 특성과 형상기억 특성을 분석하였다. 이를 위하여 메틸렌디페닐 디이소시아네이트와 1,4-부탄디올을 하드세그먼트(HS) 성분으로 하고, 소프트세그먼트(SS) 성분으로 PDMS 디올과 폴리(테트라메틸렌 에테르 글리콜)(PTMEG) 혼합폴리올을 사용하여 HS 함량이 각각 23%와 32%이면서 PDMS 함량이 다른 PU-Si를 용액중합법으로 합성하였다. HS 함량이 23%인 PU-Si의 경우 PDMS 함량 증가에 따라 SS의 냉결정화온도($T_{cc}$)와 용융결정화온도는 증가하였으나 용융온도($T_m$)에는 변화가 없었다. HS 함량이 32%인 시료들의 경우 PTMEG의 $T_m$이 HS 함량 23%인 시료들보다 약간 높은 온도에서 나타났으며 $T_{cc}$는 관찰되지 않았다. PDMS 성분이 포함된 PU-Si 필름들은 PU에 비해 형태고정성은 약간 좋지 않지만 형상기억 효과는 더 우수하였다.

This experiment evaluates wintering ability to maintain green color of lawn grasses during winter and investigates the effects of top dressing of fertilizer on improving green color during regrowth. Kentucky blue-grass could maintain green color and leaf chlorophyll content better than tall fescue and creeping bentgrass in winter. All three grasses in this experiment have shown the excellent wintering ability. In enhancing the recovery of green color at the early stage of regrowth, the mulching effect with rice straw was highly significant for creeping bentgrass. Green color recovery in grasses during its regrowth was better at the top dressing plots than at the plots without top dressing, but when fertilizer application levels were increased, green color in lawn grass did not significantly change. Although green color in tall fescue, Kentucky bluegrass, and Korean lawngrass could be maintained during summer, the green color of creeping bentgrass is reduced significantly with high temperature. Top dressing after winter and mowing improved leaf chlorophyll content and green color in tail fescue and Kentucky bluegrass significantly. However, Korean lawngrass did not respond significantly with increased levels of fertilizer.
