Orientation-controlled self-assembled monolayers of zeolite nanocystals on glass with 4-diisocyanates as covalent linkers

김익진,Young Mi Kim 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.1

High-quality TMA-A zeolite nonocrystals were synthesized using a hydrothermal method from a Al(i-pro)3 : 2.2 TEOS : 2.4TMAOH : 0.3 NaOH : 200H2O composition. The average size of the zeolite crystal used was 60-130 nm with a lattice constant of 12.389 Å. The well-oriented self-assembled monolayers of zeolite with a face parallel to the glass surface treated with the 4-diisocyanates (DIC-4) showed only planes of the form of {h 0 0} by covalent linkages. High resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and dynamic light scattering (DLS) were used to characterize the self-assembled monolayers of synthesized zeolite crystals.

Zero level thermal expansion materials based on ZrTiO4-Al2TiO5 ceramics synthesized by reaction sintering

김익진,Hyung Chul Kim 한양대학교 세라믹연구소 2004 Journal of Ceramic Processing Research Vol.5 No.4

Low thermal expansion materials based on Al2TiO5 ceramics are of great importance because they can be mixed with other materials having positive thermal expansion coefficients to make composites which have a zero or negative thermal expansion coefficient. Zero level thermal expansion materials based on Al2TiO5-ZrTiO4 (ZAT) composites up to 1000ºC were synthesized by reaction sintering. The ZAT composites also had a much lower thermal expansion coefficient (0.2~1.3×10−6/K) than that of polycrystalline Al2TiO5 (1.5 × 10−6/K). These low thermal expansion coefficients are apparently due to a combination of microcracking caused by the large thermal expansion anisotropy of the crystal axes of the Al2TiO5 phase. The thermal properties of the ZAT composites were analyzed after various thermal treatment by scanning electron microscopy, X-ray diffraction, and a dilatometer.

Well-controlled cubic nanocrystals of TMA-A zeolite with a size of 60~100 nm were synthesized by a hydrothermal method in a solution with a Al(i-pro)3: 2.2 TEOS: 2.4 TMAOH: 0.3 NaOH: 200H2O composition. The single TMA-A nanocrystals has an average lattice constant of 24.61 Å and a surface area of 742.36 m2/g. A thermal treatment of the TMA zeolite crystals resulted in their becoming amorphous above 900 oC. Environmental scanning electron microscopy (ESEM), high resolution transmission electron microscopy (HRTEM), X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and a DTA/TGA and BET analysis were used to characterize the initial materials and the products obtained after various heat treatments.

Alumimium Titanate-Mullite 복합체는 $Al_{2}O_{3}$분말 알콜용액에서 $Si(OC_{2}H_{5})_{4}$와 $Ti(OC_{2}H_{5})_4$ 의 단계적인 가수분해로 합성하였다. Sol-Gel 방법으로 합성된 모든 분말은 비정질과 단분산이고 좁은 분말크기의 분포를 보였다. 소결체($1600 ^{\circ}C$/2h)는 임계분해온도인 $1100^{\circ}C$에서 100시간 동안과 750와 $1400^{\circ}C$ 100시간동안 반복적인 열적 내구성 및 열충격 시험을 수행하였다. 가장 좋은 열적 내구성은 aluminium titanate함유량이 70rhk 80vol%일때 얻어졌으며, 이들은 위 실험을 한후 아주 적은 미세구조와 열팽창 곡선의 변화를 나타내었다. 소결체 미세구조의 붕괴는 주사현미경, X-선회절분석과 Dil-atometer로 연구하였다. 위 연구는 이와같은 과정에 의하여 합성된 aluminium titanate-mullite복합체의 서비스 수명을 예상하기 위하여 시도되었다. The composites in the system aluminium titanate-mullite were synthesized by stepwise alkoxide hydrolysis of tetraethylorthosilicate, Si(OCLH5), and titaniumtetraethoxide, $Ti(OC_{2}H_{5})_4$ in $Al_{2}O_{3}$ ethanolic colloidal solution. All particles produced by sol-gel-process were amorphous, monodispesed and had a narrow particle size distribution. Sintered bodies at $1600 ^{\circ}C$ for 2h were subjected to prolonged durability tests-on the one hand annealing at the critical decomposition temperature of $1100 ^{\circ}C$ for lOOh and on the other cyclic thermal shock between 750 and $1400 ^{\circ}C$ for 100h. The best thermal durability was achieved by a composition containing 70 and 80 vol% aluminium titanate, which showed little change in microstructure and thermal expansion cycles during the tests. The microstructural degradation of samples studied using scanning electron microscopy, X-ray diffraction, and dilatometry, was presented here. The study was conducted in order to predict the service life of aluminium titanate-mullite ceramics formed by this processing route.

여러가지 화학 조성을 갖는 aluminium titanate mullite복합제는 $AI_2O_3$분말을 알콜 분산용액에서 $Si(OC_2H_5)_4$과 $Ti(OC_2H_5)_4$의 단계적인 가수 분해로 합성되었다. Mullite함량이 20-50vol%인 소결체($1600^{\circ}C$/2h)는 비교적 높은 강도와 낮은 열팽창 계수를 갖는 aluminium titanate를 개발할 수 있는 가능성을 보였다. 이와 같은 결과는 mullite로 인한 aluminium titanate의 입자 크기의 억제와 미세균열에 의하여 얻어졌다. aluminium titanate의 함량이 70-80vol% 복합재료는 우수한 열충격 저항성을 지녔으며 상온 강도는 31-45MPa이었다. 열충격 저항성, 영률, sound velocity화 열팽창 계수가 연구되었다. Aluminium titanate-mullite composites with varying chemical compositions were prepared by the stepwise hydrolysis of $Si(OC_2H_5)_4$, and $Ti(OC_2H_5)_4$in $AI_2O_3$ ethanolic colloidal dispersion. Sintered bodies having 20-50~01% mullite at $1600^{\circ}C$ for 2h have shown, that it is possible to develop an aluminium titanate with moderately high strength and low thermal expansion coefficient. This was obtained by inhibiting grain site of aluminium titanate with mullite and microcracks. Those with 80-70vol % aluminium titanate have excellent thermal shock resistance and has room-temperature strengths of 31-45MPa. The relation between thermal shock resistance and strength, Young's modulus, sound velocity and thermal expansion coefficient was discussed.

The characteristics of $Al_2TiO_5$ ceramics were influenced by the additives and the heat treatment that controls the microcrack behavior at grain boundaries. The effect of additives on $Al_2TiO_5$ ceramics were investigated in terms of mechanical properties and thermal expansion at high temperature. The $Al_2TiO_5$ were synthesized at $1500^{\circ}C$, $1550^{\circ}C$ and $1600^{\circ}C$ for 2h by reaction sintering. The formation of $Al_2TiO_5$ phase was increased by additives that enhanced the volume of the microcrack that can lead to low thermal expansion. The mechanical properties of the stabilized $Al_2TiO_5$ ceramics were increased remarkably at $1100^{\circ}C$, $1200^{\circ}C$ and $1300^{\circ}C$ due to the oneset of mechanical healing of grain-bondary microcracks at a high temperature. The amount of microcrack was decreased at lower sintering temperature that causes the increase of mechanical properties at high temperature.

문학비평 방법론의 치유적 활용 가능성에 관한 소고 - 샤를르 모롱의 심리비평 방법론을 중심으로 -

La psychocritique de Charles Mauron est une des méthodes nouvellement appliquée dans le domaine de la critique littéraraire des années 1960s. Comme d’autres nouvelles critiques, elle emprunte aussi une méthodologie de tout autre domaine scientifique : la psychanalise. Pour nous qui s’intéresse toujours à chercher les valeurs thérapeutique de la littérature, cette rencontre de l’art et la science peut être un poteau de départ pour un trajet de recherche qui nous amènera à l’application créative de la méthodologie des critiques littéraires. Dès sa naissance, la critique littéraire est considérée comme un des incontestables genres comme le roman ou la poesie, qui constituent une discipline à part entière : la littérature. Pourtant la situation actuelle ou son rô̂le est fortement contesté nous fait poser un ensemble des questions. Est-ce qu’elle garde toujours le même statut qu’au 20ème siecle ? Et si on ne pourrait pas trouver son vrai rô̂le dans le discipline littéraire, où est-ce qu’on trouve les moyens de revaloriser ce qu’on a accumulé laborieusement depuis plus d’un siècle ? Dans cet article on a tenté de proposer un moyen visant à revaloriser et à favorier notre héritage riche de la critique littéraire en les applicant à une autre discipline, la littera-thérapie voire l’humanithérapie. Pour en avoir une idée concrète, nous avons montré la possiblité de se servir de la méthode de psychocritique pour analyser des textes littéraires ou non littéraires afin qu’on y discerne le monde d’inconscience de ceux qui écrivent espérant l’experince thérapeutique. L’application thérapeutique des théories des critiques littéraires minutieusement étudiées à l’activité thérapeutique sur le champ demande encore des travailles. Pourtant nous contentons ici d’avoir trouver une des solutions grâce auxquelles nous, les littéraires ne perderont pas tous ce que nous avons élaborés depuis plus d’un siècle.

사이코드라마와 변별된 인문,예술치료로서의 연극치료

Est-ce le psychodrame peut etre considere comme une partie de l`Humanitude therapie ou de l`Art-therapie? On rencontre tres souvent de diverses versions de psychodrame dans le media, surtout dans des emissions a la television. Mais sa forme de se presenter est presque toujours extremement simplifiee en mettant trop d`importance sur l`effet de la catharsis. Le psychodrame de ce genre ne soigne pas la qualite esthetique du theatre qui est un des genres artistiques par exellence. L`etat retabli par l`effet de catharsis n`est pas aussi durable comme le veulent des amateurs de la psychodrame. Pour bien garder l`etat conscient positif recupere en vivant le moment du catharsis, on doit passer encore deux autres etapes curatives; celle de l`abreaction et celle de la realisation esthetique(ou le phenomene esthetique au sens nietzscheen du terme). Celle-ci est un element indispensable de tous les genres de l`art-therapie. Et l`humanitude therapie partage cette conception de l`art-therapie. Seulement au lieu de l`etape de la realisation esthetique on ajoute l`etape de la pedagogie au sens freireen du terme. Donc le psychodrame qui ne comprend in l`etape de la realisation esthetique ni celle de la pedagogie ne digne pas d`etre appele l`art-therapie ou l`humanitude therapie.

감정노동과 인문치료 - 감정노동 진단도구 개발을 중심으로

김익진 ( Kim Ik-jin ),백성준 ( Back Seong-june ) 전남대학교 호남학연구원 2017 감성연구 Vol.0 No.14

국회에서 <감정노동자법> 제정안이 국회의원 등 45인의 명의로 공동 발의되었다. 세부 사항들은 여전히 논의 중이지만 관련법의 필요성 및 당위성 자체에 대해서는 이견을 찾기 힘들다. 그만큼 감정노동은 우리 사회의 건강과 안녕을 위협하는 심각한 문제라는 공감대가 형성되어 있는 상황이다. 하지만 이러한 상황에도 불구하고 감정노동에 대한 연구는 사실상 걸음마 단계에 있다. 연구 논문 대부분은 감정노동의 직무 연관성에 초점이 맞추어져 있을 뿐 그 해결을 위한 연구는 거의 찾아볼 수 없다. 인문과 예술을 활용한 치유행위가 감정노동자의 소진된 마음에 새로운 의욕과 생기를 불어넣어줄 수 있다고 믿는 우리는 이 연구에서 감정노동에 대한 인문치료 프로그램의 개발을 위한 첫걸음으로 감정노동 관련 진단평가도구 개발을 시도했다. 우리는 감정노동 진단도구 제작을 위해 인문학적 경험과 문헌연구 방법을 통해 방향성을 제시하고 최종적으로 진단도구의 문항들을 완성하였다. 그러나 제시된 문항이 완성도를 갖추기 위해서는 통계적 기법을 활용한 객관적 가치의 확인이나 문항분석과 같은 구체적 연구가 추가로 이루어져야 한다. 이렇듯 현장에서의 활용을 위해서는 여전히 보완의 필요가 있음에도 불구하고 우리의 시도는 감정노동에 노출된 정도를 측정하려는 검사도구 개발의 방향을 우리의 실정에 맞게 제시했다는 점에서 의미를 찾을 수 있다. 여기에 제시된 틀과 시도된 문항들을 바탕으로 신뢰도와 타당도 높은 감정노동에 대한 진단평가문항이 완성될 수 있을 것으로 기대된다. 부언할 것은 인문치료를 위한 최종의 진단 도구는 계량화된 데이터로서의 의미를 포함하여 질적인 데이터를 기반으로 하는 종합적인 진단결과를 도출할 수 있는 도구가 되어야 한다는 점이다. Emotional labor bills were introduced by 45 lawmakers in the last 20^th Assembly. The details are still under discussion but there is no doubt about the necessity of this law. As such, an overall consensus has been reached in our society for the problem of the emotional labor that threaten our social well-being and emotional health seriously. In spite of this serious situation, the study on the emotional labor is at its basic level. Most of the researches are focused only on the job analysis factors. It is not easy to find a study which provide or suggest some solution. In our certainty of efficacity of the curative activities based on humanities therapy and art-therapy, we try to develop a diagnostic tool for the emotional labor as a first step of our long term research setting a goal to develop the therapeutic program. To the diagnostic tool, we rely on the empirical knowledge of the humanities and the literature study. But the items suggested here can not be considered as accomplished. They must be subjected to a tight statistical process and item analysis before the application in the field. Nevertheless, these items suggested here hold a meaning sufficiently significant. Because this is the first step to find solutions of the serious problem of the emotional labor which weigh heavily on especially our tired society. We expect that from this study the diagnostic tool for the problem of emotional labor would be accomplished at no very distant day.

En croyant que l`Humanitherapie peut jouer un rol e important pour les adolescents soumis a la probation, nous avons applique la theorie de la communication qui avait ete proposee lors de la 4eme conference de la Humaniterapie a Kangwon Universite en 2010. Le premier stade de l`application de la theorie pour ces adolescents est de promouvoir la capacite de la communication avec soi. Et nous avons organise un programme intitule Ecrire une future autobiographie compose en 40 seances(une seance par semaine). Et ici on a fait un bilan du programme d`ouverture en 4 seances dont le but etait d`aiguiser la curiosite et le desir d`appendre des adolescents concernant le programme et mesurer la capacite d`ecrire et la volonte de se participer. Pour la mesure on a utilise BHT(Bilan d`Humanitherapie) fonde sur la theorie de 3B de Richard Forestier. Le resultat etait bon. Les 9 adolescents y participant voulaient continuer l`activite que je leur ai proposee. De lors on continue le programme. En passant 11eme seance on peut avoir une esperence de faire achever la tache d`ecrire une autobiographie a presque tous les participants. Nous publierons le resultat avec la permission des participants pour que ces autobiographies puissent et re des itineraires de leurs vies propres.
