유동식,하진욱 한국공업화학회 2005 응용화학 Vol.9 No.1

The photodegradation of IPA according to coating conditions was examined by TiO₂/'P-25-coated aluminium metal plate. The following results can be concluded. Inorganic(KR-400), inorganic-organic hybrid(TMOS) and organic(A-9540) resins were used as binder. Ti0₂ coated surface of aluminum metal plate was clear with all binders. The activity for IPA degradation appeared to range in order A-9540>TMOS>KR-400. The optimum activity obtained when the ratio of TMOS and P-25 was 1.6:10, and when the ratio of A-9540 and P-25 was 1.0:6.0.

1. Tasks and Methods This thesis is written in an attempt to find how the Korean people has accepted Buddhism, but it is not attempted to see how the Buddhism has been indigenized in Korea as a foreign religion. Especially I tried to see the forms of accepting Buddhism of the people who are closely related to indigenous beliefs. First of all I employed a method to consider the structure of Korean indigenous beliefs and eventually observed the types of accepting Buddhism which are found in 'Pal-kwan-hoe' and 'Yun-dong-hoe' of Koryo Dynasty. However, the present research has been centered around defining the types of people's accepting Buddhism which have been reflected on the existing Buddhist temples. 2. Indigenous Beliefs and the Structure of Koreans' Religious Consciousness I tried to find the archetype of Koreans' indigenous beliefs in the form of ancient Korean beliefs prior to accepting foreign religions and in the belief of the existing Shamanism which are the survival of the ancient belief. I also tried to find the structure of Koreans' religious conciousness reflected on those ancient indigenous belief forms. Their religious concerns have been held with pursuing this worldly blessings such as wealth, longevity and security. The subject of their beliefs is defined in a word as deity ('Hwan-In,' 'Hwan-Ung,' 'Tankun' or Heavenly God, Earthly Goddess, Mountain God). The principle of religion is found in that man comes in fellowship with deities and brings forth the blessings by spiritual power of the deities. In order to achieve this, man comes in union with deities by means of self-nagation in which the self disappears and the other (deity) is raised high. But in its content the ultimate concern of man is centered around the realisation of his own wishes. 3. Forms of Accepting Buddhism Seen Through 'Pal-Kwan-Hoe' and 'Yun-Dong-Hoe' 'Pal-Kwan-Hoe' and 'Yun-Dung-Hoe' of Koryo Dynasty are the typical cases that they accepted a foreign religion in the principle of indigenous beliefs. Outwardly, they were Buddhist services in a form, but in contents they were nothing more than self-realization of indigenous beliefs. These two kinds of Buddhist serveices were not aimed at the practices of Buddhistic teaching but at the conventional belessings, guardianship and consolation of the dead. King Tae-Jo of the Koryo Dynasty stated outspokenly in his royal instructions that "Pal-Kwan-Hoe was not a Buddhist service but worshipping Heavenly-God, Mountain God, and Dragon-Spirit. " This was exactly an indegenous religious ritual. But 'Pal-Kwan-Hoe' and 'Yun-Dung-Hoe' continued to be practiced as a Buddhist before. 4. Types of People's Accepting Buddhism Reflected on the Buddhist Temples I conducted survey on the temples in the cities and villages which the people closely contact. In particular, 15 temples were selected for survey from Seoul, Kyung-Gi-Do Province and Chung-Chong-Do Province, which are all in the central region of Korea. a. Major Buddhist Shrines and Rituals Major Shrines are consisted of three buildings: 'Tae-Wung-Jun', 'Myung-Bu-Jun' and 'Sam-Sung-Kak.' Seeing the fact that half of the temples have no 'Myung-Bu-Jun', it is understood that the sanctuary (Tae-Wung-Jun) and 'Sam-Sung-Kak' are the shrines indispensable in the Korean Buddhist temples. However, 'Sam-Sung-Kak' is not a Buddhistic element but exists as the object of conventional indigenous belief. Major ritual activities of Buddhism are a Buddhist servece, prayers, and a memorial service for the dead. These coincide with the structure of shirines. Namely the sanctuary is a symbol of Buddhist service, 'Myung-Bu-Jun' is a symbol of a memorial service for the dead, and 'Sam-Sung-Kak' is a symbol of prayers. The fact that 'Myung-Bu-Jun' is in the weakest existence well explans that the masses are more emphatically concerned for the interests and benefits in this world rather than the blessings of the other world. b. Buddha, Bodhisattva, Deities and Prayers Buddhist images (statues) which are enshrined as the objects of belief in a temple are Sakyamuni, Amitadha Buddha, Bhaisajyaguru-vaidyrya, which are called 'Sam-Jon-Bul'(Three Major Highest Buddhas), and Aralokitesvara and Ksitigarbha. The images of deities are found on the Buddhistic paintings (icons) ; those three deities of 'Chil-Sung'(God of Great Dipper),'San-Shin'(Mountain God) and 'Tok-Sung'(The Only Holy One), and in addition, the host of Buddhistic deities. Among these, it is Aralokitesvara Bodhisattva that they mostly pray to in order to achieve their wishes for this worldly blessings. In particular, it is central that they pray to 'Chil-Sung' for longevity and birth of sons and that they pray to Mountain God for the prosperity of business. In other words, it is central to pray for the blessings of longevity and wealth in this world. They pray to Ksitigarbha-Bodhissattva for the blessings of eternal repose in the other world. But this is very weak in comparison with the fore-going. The contents of these prayers coincide actually with the contents of indigenous beliefs. c. 'Sam-Sung-Kak' and Three Deities 'Sam-Sung-Kak' is not only the center of indigenous beliefs but forms the basis of the people's religion. It is quite similar in its name to 'Sam-Sung-Sa'(Shrine of Three Holy Ones) in which three deities were enshrined and worshipped in ancient times. The only difference is found in the names of three deities from those of three deities of ancient times. 'Hwan-In-Heavenly God' is replaced by 'Chil-Sung', 'Tan-Kun' by Mountain God, and 'Hwan-Ung' by 'Tok-Sung.' In view of their names, it is the 'Chil-Sung' of Taosim, Mountain-God of Shamanism, and 'Tok-Sung' of Buddhism, and so it seems to be the central syncretistic form of Shamanism, Buddhism and Taoism. But when seen from the functions of the deities and their historical trend, 'Sam-Sung' can be identified with 'Sam-Shin'(Three Deities) of ancient times. In short, the masses accepted Buddhism on the basis of their indigenous beliefs. This is more explicit not only in various forms of prayers but in the fact that they directly worshipped Three Deities. 5. Indigenous Beliefs and the Types of People's Accepting Buddhism It is the indigenous beliefs that formed the basis of people's accepting Buddhism. Buddhism as a foreign religion is always exposed on the surface. But inside, indigenous beliefs are always dominant as ever. The masses accepted Buddhism in such a way as it is well accomodated with their indigenous beliefs. Therefore, they did not try to make themselves Buddhists in accordance with the authentic Buddhist teachings and doctrines but did indigenize Buddhism for self-realization. It is well expressed in their prayers in concrete terms and in the structure of shrines and temples. In particular, the existence of 'Sam-Sung-Kak' explains this point, in which the types of people's accepting Buddhism are found.

광변색 코팅 렌즈의 퇴색속도 평가

유동식 대한시과학회 2015 대한시과학회지 Vol.17 No.1

목 적: 하드코팅과 광변색 코팅을 동시에 실시하여 제조한 광변색 렌즈에 대한 퇴색속도 중심으로 광학 적 특성을 조사하여 비교하고자 하였다. 방 법: Tetraethyl orthosilicate와 3-glycidoxypropyltrimethoxysilane로 조성된 하드코팅 액에 적, 황, 청색의 광변색 물질을 각각 혼합하고, 플라스틱 안경렌즈 표면에 플로우 코팅 후 열경화하였다. 코팅된 광변색 렌즈의 표면 물성과 광학적 특성을 평가하였다. 결 과: 광변색 코팅 렌즈는 우수한 부착력과 무코팅 렌즈보다 강한 표면 경도로 하드코팅의 특성을 보였 다. 광변색 코팅 렌즈의 최대흡광도(λmax)는 적색, 황색, 청색 렌즈에서 각각 499, 418, 606 nm이었으며, 이를 기준으로 반감기에 의한 퇴색속도는 청, 적, 황색의 변색 렌즈 순으로 각각 204, 416, 670 sec이었다. 코팅 렌즈의 퇴색속도는 spironaphthoxazine계인 청색이 naphthopyran계인 적색과 황색보다 빨랐고, 동일 계열에서도 폐환상태의 열적 안전성이 클수록 빠르게 평가되었다. 결 론: 광변색 코팅 렌즈의 퇴색속도는 열적으로 안정한 상태로 가역하려는 광변색 물질의 특성에 따라 달라진다. 따라서 광변색 코팅에서 코팅 성분보다 광변색 물질이 갖는 고유의 퇴색속도를 우선적으로 고려 하여야 할 것이다. Purpose: The aim of this study was to investigate and compare optical properties focussing on the fading rate of photochromic lenses, which were prepared by in situ hard and photochromic coating. Methods: Photochromic dyes with red, yellow and blue were mixed in the hard coating solutions, which were composed by tetraethyl orthosilicate and 3-glycidoxypropyltrimethoxysilane. Photochromic coatings were prepared on plastic ophthalmic lenses by flow coating and cured thermally. The optical properties and surface characteristics of the coated lenses were evaluated. Results: The photochromic lenses by coating showed good adhesion, stronger surface hardness than uncoated lenses. Maximum absorbances (λmax) for photochromic lenses with red, yellow and blue dye were 499, 418, 606 nm, respectively. Fading rates based on half-life time at λmax were 204, 416, 670 sec in order of blue, red and yellow photochromic lenses. The fading rate of blue dye with spironaphthoxazines was faster than that of red and yellow dye with naphthopyrans, and that of the same classes was fast with increase of thermal stability in colorless state. Conclusions: Fading rates of the photochromic lenses by coating depend on characteristics of photochromic dyes involving thermally reversible stable form. Therefore, in photochromic coatings, the intrinsic fading rate of photochromic dyes may be considered prior to coating compositions.

새 천년을 앞둔 현시점에서 밀레니엄이 갖는 문화적 의미를 어디서 찾아야 할까? 그 것은 오늘의 위기와 어두움을 초래한 서양 문명이 아니라 동서양이 조화를 이룬 석굴암의 예술에 있다. 온 누리는 문화와 역사를 빛나게 할 동방의 등불을 기다리고 있고 이것을 밝힐 사명이 우리에게 주어져 있다. 모든 사욕과 집착을 떠나 무아의 문화를 창조하는 종교인, 이들이 무아의 사람들이다.
