Kinetics of Carbon Dioxide Reaction with Aqueous Diethanolamone

박문기 경산대학교(대구한의과대학) 1999 環境硏究 Vol.4 No.1

The kinetics of the reaction between CO₂and aqueous diethanolamine (DEA) were estimated over the temperature range of 293 to 343 K from absorption data obtained in a laminar liquid jet absorber. The absorption data were obtained over a wide range of DEA concentrations and for CO₂ partial pressures near atmospheric. A rigorous numerical mass transfer model based on penetration theory in which all chemical reactions are considered to be reversible was developed and used to estimate kinetic rate coefficients from the experimental absorption data. The kinetic data were found to be consistent with the zwitterion mechanism. The scare zwitterion rate coefficient estimates reported in the literature are in fair agreement with the results of this work.

In this work, we have investigated the dependence of annealing temperature(T$\_$a/) on optical and electrical properties of amorphous hydrogenated SiC(a-SiC:H) films. The a-SiC:H films were deposited on corning glass and p-type Si(100) wafer by PECVD (plasma enhanced vapor deposition) using SiH$_4$+CH$_4$+N$_2$ gas mixture. The experimental results have shown that the optical energy band gap(E$\_$opt/)of the thin films annealed at high temperatures have shown that the graphitization of carbon clusters and micro-crystalline silicon occurs. The current-voltage characteristics have shown good electrical properties at the annealed films.

話頭의 내재적 구조 一考

박문기 한국불교학회 2010 韓國佛敎學 Vol.58 No.-

Ganhwa Seon is a practice method more concise and straightforward than any other, which is obviously a unique merit point of Ganhwa Seon. Holding up one subject as a key for solution and concentrating only on it is the most concise and simple method among the other self-oriented practice methods and also attaining directly the ultimate solution through hwadu is really the most effective and straightforward one. Then, how can we attain the power of breaking down the whole through penetrating only a piece of hwadu? As a result of this study I can sum up the following three points;The first point is the unique characteristic of hwadu investigation as the direct objective method. Ganhwa Seon pursues to directly accomplish the final target in terms of both investigation method and practicing objective. Unlike the other methods, in Ganhwa Seon there is not any gradual procedure defined such as the grade, the step or the state. It consistently seeks the final target, namely ultimate enlightenment through the unique method of hwadu investigation. Secondly, hwadu itself belongs to the realm of real Dharma. Hwadu is the targeted subject to be broken through and at the same time it has the same origin as all true nature if defined from the viewpoint based on true form of nature or one's true nature. The realms of existing phenomena are all derived from the fundamental origin and simultaneously the fundamental origin is contained in the realm of phenomena because it cannot survive by itself. Based upon this doctrine, the fundamental essence of hwadu contains the true Dharma of reality though its form belongs to the realm of phenomena. The third point is the feature of integrative aspects contained in hwadu. Since a single hwadu is interpenetrated and correlated with all realms of Dharma, complete enlightenment is realized if a piece of hwadu is broken through and realization of enlightenment enables us to master all Dharmas. Just like Indra’s net of the ten profound aspects doctrine where all the beads are shining on a single bead and the doctrine of the three thousand worlds in a single thought based on the Tiantai school where all the existences in the universe are contained in a thought, hwadu is the realm of true nature embracing the whole realms of Dharma. Therefore, if we break through a single hwadu, then we can attain perfect enlightenment by cutting off all of the ten thousands doubts. 중국에서 형성되었지만 오늘날 한국불교의 대표적 수행법으로 자리하고있는 간화선은 깨달음을 얻기 위한 방법으로서 화두 참구를 강조하고, 1700공안으로 언급되는 수많은 화두 중에서 오직 단 하나의 화두만을 타파하면완전한 깨달음을 얻게 된다고 말한다. 참구하는 화두에 어떤 내재적 구조,기능이 있기에 이러한 주장이 가능한 것인가. 본 논문은 이에 대한 고찰이다. 첫 번째로 살펴지는 것은 화두 참구법이 가진 목표의 직접 지향성이다. 간화선은 수행 목표나 참구 방법 모두 깨달음이라는 최종 목적지를 곧바로지향한다. 여타의 수행법에서 보이는 점차적인 방법이나 계위와 같은 것은전혀 없다. 모든 단계적인 것을 배제하고 오로지 구경의 깨달음을 직접 목표로 한다. 따라서 화두를 타파하면 곧 깨달음이고 그렇지 못하면 미혹한 상태의 지속이다. 또한 화두는 이미 그 자체로 眞法이다. 선사들의 가르침에 의하면, 모든존재는 실상으로부터 파생한 것이고 실상은 만유존재에 내재하며, 동시에 實相卽萬有이다. 화두가 비록 타파해야 할 대상이지만 실상으로부터 파생해 실상을 내포하고 또한 실상즉화두이므로 화두를 타파하기만 하면 곧바로 실상의 체득이 되는 것이다. 뿐만 아니라 하나의 화두에는 법계 일체가 함축되고 연관되어 있어 단지그 하나의 화두를 타파하는 순간 그대로 전체의 타파, 전체의 깨달음으로 이어진다. 화엄의 십현문이나 천태의 관문이 이의 이해를 크게 돕는다. 특히인다라망 중심의 이론구조나 일념삼천설은 이의 이해에 단연 두드러진다.

위앙의 禪思想 形成 過程考

朴文基 동국대학교 대학원 1992 大學院硏究論集-東國大學校 大學院 Vol.22 No.-

This paper is for study of Kuei-Yang(위앙) Seon. Kuei-Yand Seon and Lin-chi(臨濟) Seon came into the world under Ma-Tsu Tao-il(馬祖道一;709-788). Kuei-Yand seon was established by Kuei-shan Ling-Yu(위산영우:771-853) and Yand -Shan Hui-Chi(仰山愚寂). The core thought of this Seon was a deed of non-attachment and having nothing to do . Kuei Shan claimed that if people would be in the state of having nothing to do without wrong perception, good thinking, bad habit, we could call them who got enlightenment or had nothing to do his whole life long and Yand-Shan also said we had not so to have concerns even the holy thing. Their thoughts was when we remove bad or good feelings and thinking habits and realize our nature and pervade the root of mind then we can be a man who has nothing to do his whole life long. A deed of non-affachment and having nothing to do of the Juei-Yand was the core thought of the Chinese Buddhism and also the point of the Patriarcha-I-Seon which can get from perfect enlightenment. In this thought there are Ma-Tsu's thought which persuit the real from phenomena to origin and return to the phenomina; practice Seon in the daily life. For example; "When one becomes to tired then go to sleep and when one becomes to energetic the practice Seon(Meditation)." It was the representative thought of Ma-Tsu who told the real is in our daily life. On the other hand. Kuei-Shan's thought explain the ligic with the illogic but Yand-Shan's thought transcend the ligic and illogic and return to general daily life. Their special method in order to teach their disciples using circle has harmonious character as the relationship of parents and their children.

평면 교반조에서의 CO_2 기체흡수에서 교반속도에 따른 기-액 계면 면적에 관한 연구

박문기,문영수 한국환경과학회 1994 한국환경과학회지 Vol.3 No.4

Catalytic slurry reactors, in which a solid maintained in the form of fine particles suspended in a liquid, are frequently used in chemical and biochemical and industries. In these processes the particle loading is normally low so that the effects of particles on the liquid-film mass transfer coefficent and the gas-liquid interface area are assumed to be negligible. But it is known from the works, amongst others, that the finely powdered activated carbon can increase the gas-liquid mass transfer significantly in surface-aerated reactors. The stirred cell (13.2cm inside diameter) contained four baffles and at the stirring speeds range of 80∼300rpm, the gas-liquid interfacial area could be considered as that of the cross section of the vessel (that is, 130.1㎝2). When the stirrer speeds were increased, the effective interfacial area was slightly higher than the geometric area and was obtained experimentally from the Danckwerts'plots.

근기론으로서의 돈점론

박문기 한국불교학회 2013 韓國佛敎學 Vol.67 No.-

선 수증론의 핵심 요소인 돈점론은 선종의 오랜 역사 속에서 때로는 논쟁의 중심이 되기도 하고, 때로는 많은 수행자들에게 큰 길잡이의 역할을 하며 존재해 왔다. 그간 돈점론에 대한 연구가 상당하지만 그 내용은 의외로 특정 부분에 치우쳐 있음이 살펴진다. 예를 들어 悟⋅修 및 돈점 자체의 내용에 대한 것, 돈점 논쟁의 역사와 주요 내용, 그리고 특정 선사의 돈점관에 대한 것 등이다. 반면 돈점론을 보다 근본적 입장에서 고찰하고 논점을 다루려는 글은 그렇게 잘 보이지 않는다. 본 글은 달마 이후 선종사 최초로 돈점을 다룬 육조혜능의 ‘법에는 돈점이 없고 사람에게 이둔이 있다’는 ‘法無頓漸 人有利鈍’의 구절을 돈점론의 핵심으로 보고 여기에 입각해 돈점론을 재조명하고자 한 글이다. 육조와 이후의 여러 선사들은 대체적으로 획일적이지 않은 돈점의 가르침을 보이고 있다. 반드시 돈오돈수해야 한다든가 혹은 돈오점수만을 주장하고 있는 선사가 없는 것은 아니나 신회, 마조, 황벽, 위산 등 거의 대부분의 선사들이 양자를 함께 언급하고 있다. 이는 오로지 수행자들의 근기를 살피고 거기에 입각해 가르침을 주고 있기 때문인 것으로 보인다. 특히 여러 선사들이 돈오는 상근기가 하는 것이요, 돈오돈수는 상상근기가 할 수 있는 것, 돈오점수는 상근기에 해당되는 것이라 하고, 또 중하근기자는 부지런히 수행하라는 勉修를 설하고 있다. 해당 근기자에 적합한 돈점의 오수가 있다는 내용이다. Throughout the long history of the Seon (Zen, Chan) School,sudden and gradual enlightenment, the two core theories of Seonpractice, sometimes stood at the center of controversial debates and atother times functioned as guiding principles for many practitioners. Although a considerable amount of research on sudden and gradualenlightenment has been done, it has concentrated too much on certainspecific areas. Most of the research has dealt with the following:enlightenment, cultivation, the theories of sudden and gradualenlightenment, the history and essential content of the debates onsudden versus gradual enlightenment and specific Seon masters’ viewson sudden and gradual enlightenment. However, little research has beendone to explore in a general way the theories of sudden and gradualenlightenment from a fundamental stance and to resolve the issues ofthe debates. The Sixth Patriarch Huineng was the first to deal with the issuesof sudden and gradual enlightenment since Bodhidharma; he said,“Dharma is not sudden or gradual. Rather it is people who are sharpor dull.” I regard this quote by Huineng as the core issue of the suddenversus gradual controversy and will try to shed light on the sudden vs. gradual debate based on this quote. From this perspective, Huinengtaught the Dharma and guided students to internalize it. When teaching,Huineng took into account the individual circumstances of each student; that is, he taught each student according to their spiritual capacity. Thismethod of teaching has been described in various ways, including theexpressions: “sudden enlightenment,” “sudden cultivation,” “supremecapacity,” and the admonition to “practice diligently after listening tothe teaching of sudden enlightenment.”Many Seon masters after Huineng were not consistent in teachingsudden and gradual enlightenment. Some masters believed exclusivelyin “sudden enlightenment and sudden cultivation,” others in “suddenenlightenment and gradual cultivation.” Still others taught both. Without considering the concept of “student capacity,” I think it isimpossible to explain sudden and gradual enlightenment, as well asenlightenment and cultivation. I base this statement on the fact thatvarious Seon masters specifically mentioned certain practices for certaincapacities, saying such things as: “Sudden enlightenment is for the[student of] higher capacity”; “Sudden enlightenment and suddencultivation is for the [student of] supreme capacity”; “Suddenenlightenment and gradual cultivation is for the [student of] highercapacity”; and “The [students of] medium and lower capacity shouldpractice diligently.” Moreover, their emphasis on faith, arousal of theaspiration for enlightenment and right view, attests to the excellenceof a teacher’s means in teaching Seon practice and doctrine in that theyadmonish practitioners not to take a narrow-minded view of inherentcapacity but rather to maximize their own enlightenment andcultivation.
