본 연구는 인도 베단타 철학의 니다디아사나(Nididhyāsana)와 초기불교의 사띠팟타나(Satipaṭṭhāna) 수행을 비교 분석하여 자아해체(self-dissolution) 과정의 심리적·신경학적 기제를 탐구하였다. 통합 문헌고찰 방법론을 적용하여 두 수행의 철학적 구조와 관련 뇌과학 연구를 종합적으로 분석하였다. 연구 결과, 니다디아사나는 상위 인지 기능과 철학적 사유를 통해 자아 개념을 해체하는 반면, 사띠팟타나는 감각 기반의 지속적 주의력으로 자아 감각을 해체하는 데 초점을 둔다는 차이를 밝혔다. 신경생리학적으로 니다디아사나는 전전두엽 및 디폴트 모드 네트워크(DMN)의 억제를, 사띠팟타나는 insula와 전대상피질(ACC)의 활성화를 기반으로 함을 확인하였다. 이러한 발견은 두 수행 방식의 특성을 명확히 하고, 각각의 심리치 료 및 자기 탐색 분야에서의 차별화된 적용 가능성을 시사한다. 본 연구는 동양의 전통적 수행법을 현대 심리학 및 뇌과학의 관점에서 재해석함으로써 명상 기반 자아 개념 연구에 새로운 통찰을 제공하 고 학제간 연구의 기반을 마련하였다는 데 의의가 있다.

The feeder pipes of the primary cooling system in a pressurized heavy water reactor (PHWR) are composed of carbon steel SA 106 GR.B. On the surface of this structural material, corrosion oxide layers including radionuclides are formed due to the presence of active species from water decomposition products caused by radiation, as well as the high temperature and high-pressure environment. These oxide layers decrease the heat transfer efficiency of the primary cooling system and pose a risk of radiation exposure to workers and the environment during maintenance and decommissioning, making effective decontamination essential. In this study, we simulated the formation of the corrosion oxide layer on the surface of carbon steel SA 106 GR.B, characterized the formed corrosion oxide layer, and investigated the dissolution characteristics of the corrosion oxide layer using oxalic acid (OA), a commercial chemical decontamination agent. The corrosion oxide layer formed has a thickness of approximately 4 μm and consists of hematite ( Fe2O3) and magnetite ( Fe3O4). The carbon steel coupons with formed oxide layers were dissolved in 10 mM and 20 mM OA solutions, resulting in iron ion concentrations of 220 ppm and 276 ppm in the OA respectively. In 10 mM and 20 mM OA, the corrosion depths of the coupons were 8.93 μm and 10.22 μm, with corrosion rates of 0.39 mg/cm2·h and 0.45 mg/cm2·h, respectively. Thus, this demonstrates that higher OA concentrations lead to increased dissolution and corrosion of steel.

The team has studied the relationship between the ability of the coals to be dissolved in crude anthracene oil and their composition. The coal samples taken from different deposits in Russia and Mongolia were characterized by different stages of metamorphism and tested by the Fourier transform infrared spectroscopy and Carbon-13 nuclear magnetic resonance. The data of a correlation analysis enabled us to find out that an amount of aromatic structures in coal macromolecules provided the main influence on the thermal dissolution of the coals. The middle-rank coals had the highest rates of coal organic matter transfer to liquid products. The data showed that the dissolution process was accompanied by destruction of weak bonds among aliphatic groups. The amount of methylene groups in the aliphatic part of coal macromolecules had a direct impact on conversion of the coal organic matter into soluble products.

In this study, a comparative dissolution experiment was conducted between an immediate-release and a controlled-release vitamin C tablet applied with a technology to control the dissolution of vitamin C to maintain the vitamin C level in the human body. In order to confirm the dissolution rate (%) of vitamin C tablets, HPLC determination was conducted based on the dissolution test methods in the ‘Korean Pharmacopoeia (No. 2020-88),’ ‘Guidelines on Specifications of Dissolution Tests for Oral dosage Forms,’ and ‘Standard and Specifications for Health Functional Foods (No. 2020-63)’ from Ministry of Food and Drug Safety (MFDS). In addition, the dissolution pattern between the immediate-release tablet and the controlled-release tablet was comparatively analyzed. The analysis result confirmed that the immediate-release vitamin C tablet was 100% dissolved after 45 minutes, while the controlled- release vitamin C tablet was 100% dissolved after 480 minutes (8 hours). Furthermore, the dissolution rate (%) at 60 minutes was slower than that of the immediate-release vitamin C tablet. Based on these results, this study confirmed that the dissolution rate (%) test and development of controlled-release tablets containing vitamin C as the main component a re possible.

The surface of silicon dummy wafers is contaminated with metallic impurities owing to the reaction with and adhesion of chemicals during the oxidation process. These metallic impurities negatively affect the device performance, reliability, and yield. To solve this problem, a wafer-cleaning process that removes metallic impurities is essential. RCA (Radio Corporation of America) cleaning is commonly used, but there are problems such as increased surface roughness and formation of metal hydroxides. Herein, we attempt to use a chelating agent (EDTA) to reduce the surface roughness, improve the stability of cleaning solutions, and prevent the re-adsorption of impurities. The bonding between the cleaning solution and metal powder is analyzed by referring to the Pourbaix diagram. The changes in the ionic conductivity, H2O2 decomposition behavior, and degree of dissolution are checked with a conductivity meter, and the changes in the absorbance and particle size before and after the reaction are confirmed by ultraviolet-visible spectroscopy (UV-vis) and dynamic light scattering (DLS) analyses. Thus, the addition of a chelating agent prevents the decomposition of H2O2 and improves the life of the silicon wafer cleaning solution, allowing it to react smoothly with metallic impurities.

The bone cement used for vertebroplasty must be sufficiently injectable. The introduction of granules reduces the amount of liquid required for liquefaction, implying that higher fluidity is achieved with the same amount of liquid. By employing β-tricalcium phosphate granules with an average diameter of 50 μm, changes in injectability are observed based on the paste preparation route and granular fraction. To obtain acceptable injectability, phase separation must be suppressed during injection, and sufficient capillary pressure to combine powder and liquid must work evenly throughout the paste. To achieve this, the granules should be evenly distributed. Reduced injection rates are observed for dry mixing and excessive granular content, owing to phase separation. All these correspond to conditions under which the clustered granules weakened the capillary pressure. The injected ratio of the paste formed by wet mixing displayed an inverted U-type shift with the granular fraction. The mixture of granules and powder resulted in an increase in the solid volume fraction, and a decrease in the liquid limit. This resulted in the enhancement of the liquidity, owing to the added liquid. It is inferred that the addition of granules improves the injectability, provided that the capillary pressure in the paste is maintained.

The effect of precipitation and dissolution of Si on the thermal diffusivity in the Al-Si alloy system is reported in this study and solution heat treatment followed by aging treatment is carried out to determine the effects of heat treatment on the thermal characteristics. The solution treatment is performed at 535 oC for 4 and 10 h and then the specimens are cooled by rapid quenching. The samples are aged at 300 oC for 4 h to precipitate Si solute. The addition of 9 wt% silicon contents makes the thermal diffusivity decrease from 78 to 74 mm/s2 in the cases of solid solution treated and quenched samples. After quenching and aging, the Si solute precipitates on the Al matrix and increases the thermal diffusivity compared with that after the quenched state. In particular, the increase of the thermal diffusivity is equal to 10 mm/s2 without relation to the Si contents in the Al-Si alloy, which seems to corresponded to solute amount of Si 1 wt% in the Al matrix.

In this study, graphene oxide(GO) was used as drug carriers to amorphize poorly watersoluble drugs via a co-spray drying process. Two poorly water-soluble drugs, fenofibrate and ibuprofen, were investigated. It was found that the drug molecules could be in the graphene nanosheets in amorphous or nano crystalline forms and thus have a significantly enhanced dissolution rate compared with the counterpart crystalline form. In addition, the dissolution of the amorphous drug enwrapped with the graphene oxide was higher than that of the amorphous drug in activated carbon (AC) even though the AC possessed a larger specific surface area than that of the graphene oxide. The amorphous formulations also remained stable under accelerated storage conditions (40°C and 75% relative humidity) for a study period of 14 months. Therefore, graphene oxide could be a potential drug carrier and amorphization agent for poorly water-soluble drugs to enhance their bioavailability.

This article aims to introduce and critically analyze the jurisprudence and its application in the UPP case in South Korea with reference to the ECtHR case law. In this controversial case, the CCK decided to dissolve the UPP and, without any basis in positive law, disqualify five National Assembly members affiliated with it. It is argued that when the CCK attempted to articulate the principle of proportionality that the ECtHR case law has firmly developed in this field and to apply it to this case, standards governing the dissolution of political parties were distorted at least in two ways. First, it substituted ‘social need’ for “pressing social need.” Second, it deliberately omitted the requirement of ‘sufficient imminence.’ In addition, the reasoning of the majority of eight justices based upon the rule of evidence in civil proceedings can also be criticized for being too abrupt to be justified in this highly controversial case of constitutional importance.

The purpose of this paper is to examine the dissolution process of Dongnae-bu Dongheon Block(東萊府東軒 一廓) under the Rule of Japanese. The results of this study are summarized as follows. First, the space orgnization of Dongnae-bu Dongheon Block(東萊府東軒一廓) proved to be clear on the basis of Dongnae-bu Eupji (東萊府邑誌), the ficture of Dongnae-bu(東萊府) and the Original Land Registration Map(地 籍原圖) at the end of Joseon Dynasty. Second, the old government offices, as well as Chungsin-dang(忠信堂), were converted into the local government office for the sake of Japanese colonialism. Third, the old government office and its land were transferred to the banking system(金融組合) and the educational foundation(學校組合) in the interests of Japanese colonist. Finally, the transfer land of civilian industry association forced Mangmi-ru(望 美樓) and Dokjin-daeamun(獨鎭大衙門) to remove to another site and the private lots-subdivision assisted space taking to pieces.

The nitrogen solubility and nitride capacity of CaO-SiO2-Al2O3-MgO-CaF2 slag systems were measured by using gas-liquid equilibration at 1773K. The nitrogen solubility of this slag system decreased with increasing CO partial pressure, with the linear relationship between nitrogen contents and oxygen partial pressure being -3/4. This system was expected to show two types of nitride solution behavior. First, the nitrogen solubility decreased to a minimum value and then increased with the increase of CaO contents. These mechanisms were explained by considering that nitrogen can dissolve into slags as "free nitride" at high basicities and as "incorporated nitride" within the network at low basicities. Also, the basicity of slag and nitride capacity were explained by using optical basicity. The nitrogen contents exhibited temperature dependence, showing an increase in nitrogen contents with increasing temperature.

김은국의 『순교자』는 희생양 메커니즘의 특징인 박해자의 ‘무지’와 폭력의 ‘맹목성’을 폭로한다. 1950년 한국전쟁이 발발하기 전 평양에서 목사들이 실종된 사건을 정치적으로 이용하려는 ‘장 대령’의 거짓말은, 지라르가 언급한 ‘첫사람의 돌 던지기’와 유사하다. 희생양 메커니즘의 작동을 유도하는 박해자 ‘장대령’을 통해 김은국은 희생양 메커니즘의 본질인 폭력성을 선명하게 보여준다. 작품의 중반부에서부터 서사는 “박해자에게서 희생양에게로, 그 사건을 만든 자에게서 그것을 참고 견딘 자에게로” 초점을 옮겨, 이 작품을 희생양의 텍스트로 만든다. 김은국의 영적 통찰력은 희생양 신 목사의 고뇌하는 내면, ‘신의 침묵에 절망할 수밖에 없는’ 희생양의 목소리를 생생하게 전달하였다. 신을 믿지 않는다는 처절한 절망 가운데서 ‘신 목사’는 끊임없이 기도함으로써 ‘가장 보잘 것 없는 사람들’에게 돌아가라는 예수의 명령을 실천하게 된다. 이 과정에서 궁극적으로 드러나는 것은 ‘신의 개입’이다. 무력하고 병든 모습으로, ‘희생양 메커니즘’의 작동을 중단시키려는 ‘신 목사’라는 캐릭터는 김은국의 종교적 투시력을 높이 평가할 근거가 된다.

The purpose of this study is to analyze the process of lots-subdivision within the block of Gaeksa at Dongnae-bu under the rule of Japanese Imperialism. Gaeksa of the old government office was the sanctuary that symbolized the sovereignty. Therefore it was naturally a main object of demolition and then the site was converted to other purpose. And Gaeksa was not only converted into the elementary school and the public market but the historic site also processed to break down for opening the road through Japanese Occupation of Korea. The main reasons of lots-subdivision were the transfer from state property to private ownership and the urban development project. Needless to say, the particular major reason was derived from the intention of Japanese Imperialism to destroy the traditional urban. As a result, Gaeksa can not be recognized the traces of today and contributes to the demolition of the remaining ancient building. Finally the deformed urban structure was left over from destroyed building.

In this study, the microstructure and valuable metals dissolution properties of PDP waste panel powders were investigated as a function of milling parameters such as ball diameter size, milling time, and rotational speed during high-energy milling process. The complete refinement of powder could achieved at the ball diameter size of 5 mm due to sufficient impact energy and the number of collisions. With increasing milling time, the average particle size was rapidly decreased until the first 30 seconds, then decreased gradually about at 3 minutes and finally, increased with presence of agglomerated particles of at 5 minutes. Although there was no significant difference on the size of the particle according to the rotational speed from 900 to 1,100 rpm, the total valuable metals dissolution amount was most excellent at 1,100 rpm. As a result, the best milling conditions for maximum dissolving amount of valuable metals (Mg: 375 ppm, Ag 135 ppm, In: 17 ppm) in this research were achieved with 5 mm of ball diameter size, 3min of milling time, and 1,100 rpm of rotational speed.

In this research, the indium dissolution properties of the waste LCD panel powders were investigated as a function of milling time fabricated by high-energy ball milling (HEBM) process. The particle morphology of waste LCD panel powders changed from sharp and irregular shape of initial cullet to spherical shape with an increase in milling time. The particle size quickly decreased to 15 until the first minute, then decreased gradually about 6 with presence of agglomerated particles after 5 minutes, which increased gradually reaching a uniform size of 13 consist of agglomerated particles after 30 minutes. The glass recovery, after dissolution, was over 99% at initial cullet, which decreased to 90.1 and 78.6% with increasing milling time of 1 and 30 minute respectively, due to a loss in remaining powder of the surface ball and jar, as well as the filter paper. The dissolution amount of indium out of the initial cullet was 208 ppm before milling, turning into 223 ppm for the mechanically milled powder after 1 minute, and nearly 146~125 ppm with further increase in milling time because of the reaction surface decrease of powders due to agglomeration. With this process, maximum dissolving indium amount (223 ppm) could be achieved at a particle size of 15 with 1 minute of milling.

비다공성 중공사막 접촉기를 이용하여 수용액 내 용존 산소의 농도를 조절하고자 하였으며, 용존 산소의 농도를 전산모사를 통하여 예측하였다. 공급 기체와 공급 수용액이 같은 방향으로 흐르는 병류 흐름 시스템에 대한 분리막 접촉기 공정 지배 미분 방정식을 5차 Runge-Kutta-Verner 법으로 해석하였다.
