레이저 회절발법에 의한 네마틱상 MBBA의 비선형 광학성 동력학

윤보형,이일근,김성규 성균관대학교 기초과학연구소 1997 論文集 Vol.48 No.-

170㎛ 두께의 네마틱 MBBA film에 레이저 여기빔을 교차시켜 회절발을 형성시켰을 때 회절 신호를 시간적으로 추적하여 비선형 광학 동력학적 정보를 얻었다. 여기빔의 파장이 355nm이고 펄스의 세기가 10mJ/㎠일 때 회절신호의 시간적인 모양은 sub-ms, ms이 시간대에서 구분할 수 있는 4개 성분으로 구성되어 있다. 회절발의 간격이 8㎛일 때 가장 빠른 성분은 실험기기의 한계시간(~20ns)내에서 발생하고 약 10㎲시간으로 사라지는데 이는 계면의 열확산에 기인한다. 이 성분은 탐사빔의 편광에 크게 의존해서 나타난다. 네마틱상-등방상 상전이 지점에 접근하는 온도가 되면 이 편광의존성은 감소한다. 가장 약하고 느린 성분은 100ms의 시간대에서 관찰되어지는데 cis-MBBA의 질량확산이라 볼 수 있다. sub-ms 와 ms 시간대에서 회절신호의 지배적인 중간의 두 성분은 각각 지수함수적으로 증가하고 지수함수적으로 감소함을 보여준다. 두 성분의 원인은 각각 레이저 조사에 의한 온도변화로 인해 질서도의 파괴 및 회복, 레이저에 의해 형성된 광변형 상태에 의한 질서도의 파괴 및 회복에 기인한 것으로 판단된다. 온도가 상전이 점에 가까워지면 물질의 광학 비선형도는 다차회절이 눈으로도 관측될 정도로 증가한다. 다차회절신호를 휴리에 변환하여 회절발의 모양을 합성함으로써 주로 광변형상태의 존재가 다차회절의 원인, 즉 비이상적으로 높은 비선형 광학성의 중요한 원인으로 생각할 수 있다.

屬格 {-ne}의 硏究 : 濟州島方言의 {-ne}를 中心으로

姜根保 제주대학 1976 논문집 Vol.8 No.1

Ⅰ. The genitive case of Korean language is expressed with {-uˇi] and plural is expressed with {-tuˇl}. Meanwhile, in the dialect of Jeju Island, above both functions are substituted with {-ne}. In case {-ne}is genitive case, it is composed of "Noun Class World + {-ne} + Noun Class Word" and if it is the usage of plural suffix, it is composed of "Noun Class Word + {-ne} + Pronoun Class Word". And the structure is composed with genitive case and expressed with genitive case in contexual meaning, sometimes it is expressed with plural suffix, but each of thorn is discriminated by junction. In other words, if it is + junction, it means plural, -junction it means the function of genitive case. Ⅱ. Plural suffix {-ne} is given expression to {-nai} not only a Chinese character writing of old Korean Language but also Korean language of 15 century. {-nai} corresponds to plural suffix {-ra} which has been used since ancient times in Japanese language (tε -take, nε-nare, -pε-hara, kεul-kapa) and it is similar to plural suffix; Turkish -lar, (-lor) Jungus -sal, -hal, -ul, -il Manchu -sa, ta, -te, -ri Mongolian -nar, -ut, -od, -s, etc. Consequently {-ne} can be mentioned suffix of an identical function which is equivalent to origin of Japanese {-ra}. And genitive case {-ne} is omission form of {-s} from plural suvvix {-ne}+possessive case {-s}.

濟州島方言「잇다」活用考

姜根保 제주대학교 1972 논문집 Vol.4 No.-

1. In this study I divided the inflections of Jeju dialect into -khuda, -uda, and-suda systems, and according to those inflections made up an inflections table of adjective it-ta, as the result of that those stems appear four types as follows : isi, it, si, and sit. (1) The sounds n. r. l, m.η.??.o. p. kh are preceded by the connecting condition of the sound that a stem isi shows. (2) The sounds k, n, t, s, c are preceded by a stem it and the stem it is changed into isi in case that the sounds r .l. m. and vowel are preceded by the stem it. (3) The sounds n, r. l, m, η, ??, o, p, kh are preceded by a stem si, and the sounds a, ,i,j ,m are followed by the stem si, And in the case that the stem si is followed by the sounds k, n, t, s, c, the stem si is changed into a stem sit. 2. A stem si loses the work of an inflective word. (1) si is and a/ are used as inflections of past form in dialect : the former is that of ka-si-nja?(went?), ka-sinie (went), the latter is that of ka-t-ta (went), m k -t-ta (ate), both forms are changed in all form a stem si. (2) si?? is?? which are inflection form of a stem si showing Interrogative affirmation are used as addessive case in connecting to nouns. (3) A pre-noun (in Korean) form (unconjugation adjective) sin of a stem si and sin-twi which is composed of connection of an incomplete noun-twi, -te show a dative as a postposition. And-sin-twi is similar to the word-sont??i of the Yi Dynasty in fifteenth century in usage and form. So I consider that-son-t i is changed into inflection of a stem it.

Heat stroke, a medical emergency, occurs when the body's thermal regulation is upset and unable to dissipate adequate amounts of heat with a rise in body temperature. It is characterized by hyperpyrexia, with a core temperature of 40˚C or more. hot dry skin, and central nervous system disturbance and usually results in rhabdomyolysis and multiorgan failure. Our case, a 43-year-old healthy male, was caused by a marathon, half course, on a sunny day in late summer. He suddenly fell down on the road and was delivered to a nearby hospital, where a seizure developed. He was transfered to our hospital and then displayed Central Nervous System disturbance, hot dry skin, acute liver failure, rhabdomyolysis, anurlc acute renal failure, and disseminated intravasculular coagulopathy. He was treated with general supportive care and hemofiltration. Despite the aggressive management, he died of shock on the fifth day after admission.

李根保,金亨烈 瑞逸專門大學 1991 論文集 Vol.9 No.-

시판 옥배유, 면실유, 대두유 및 미강유를 각각 단독 및 2~4종 혼합한 혼합유를 도우넛 튀김용 기름으로 사용하여 185±2℃에서 5시간동안 가열하면서 매 시간별로 도우넛을 튀긴 다음 이 도우넛으로부터 기름성분을 추출하여 본 연구의 시료유로 하였다. 이 시료유들의 산값, 과산화물값, Lovibond color, 발연점 및 AOM 안정성을 측정하여 다음과 같은 결론을 얻었다. 즉, 도우넛 튀김유로서는 면실유와 미강유가 우수하였고, 옥배유와 대두유는 부적당하였다. 이러한 결과들로 볼 때 도우넛 튀김용 기름으로는 면실유-미강유, 옥배유-면실유-미강유 및 옥배유-면실유-대두유-미강유의 혼합유계가 가장 적합하였다. Frying oils for doughnut, used for the investigation, were domestic corn germ, cottonseed, soybean and rice bran oil as well as all sorts of blented oils. Blending ratio of constituent oils for manufacturing of sample blended oils was same amount(v/v). Sample oils in this investigation are obtained by solvent extraction used for diethyl ether from doughnut samples. At thisn time, doughnuts are fried during 5 hours at 185±2℃, which is carried out 1 hour unit. We are obtained as followed result from changes of acid and peroxide value, Lovibond color, smoke point AOM stability of these sample oils. That is to say, frying stability was increased to the blending oils, cottonseed and rice bran oil were suitable but soybean and corn germ oil were not suitable as base oil of blended oil in oder to frying of doughnut. From these results, frying oil of doughnut was most suitable blended oils, which is cottonseed oil-rice bran oil, corn germ oil-cottonseed oil-rice bran oil and corn germ oil-cottonseed oil-soybean oil-rice bran oil etc.

濟州島方言의 曲用에 대하여

姜根保 제주대학 1978 논문집 Vol.10 No.1

1. There are {-i}, {-ka} in tile case which shows nominative in the dialect of Jeju-Island, and abbreviation is used together. The nominative {-i} is connected afterwards at substantive of close-syllable, and at open-syllable {-ka} is connected afterwards. In case {-i} is connected afterward at the open-syllable, it is cut down and omitted. In case nominative {-i}, {ka} are used or in case they are omitted, they are opposed to each other in contextual meaning. In case nominative {-i}, {-ka} build up compound from, they connect afterward at other case, as the compound form {-i+ka} is also expressed. {- i+ka} is compatible with lexical category and grammatical function. 2. The function of dative is showed with {-sinti}, {-sintu˘re}, {-anthi}, {-anthu˘re}, {-tu˘re} etc. {-sin} of {-sinti} is an inflextional from of adjective {sitta}, {-ti} is analyzed as {ti} which is a formal noun showing place. {-ti} of {-tu˘re} is also a formal noun showing place, {-re} has the same meaning and form as {re} of demonstrative pronoun {ire, ku˘re, cˇ∂re}. Accordingly {-tu˘re} is directive in the first function, dative is the second usage. 3. Accusative is expressed {-u˘i}, (-ru˘l}, and {-l}, at the close-syllable it is often omitted. {-u˘l} , {-ru˘l} are the case connecting forward, but they are used by mixture with {-n} etc. which shows the meaning of emphasis. And according to a descriptive inflected word {-u˘l}, {-ru˘l} are also realized to directive. 4. Genitive is showed {-ne}, {-u˘i}, {-i}, {-s}, {-h}, and sometimes it is omitted. {-ne} is used plural expression in the standard language, it is used the genitive function in dialect. Substantive preceding {-ne} is limited to substantive on persons in personel pronoun etc. {-ne} is originally considered as conversion from plural suffix to genitive. {-ss} and {-h} are also showed genitive function. Classification of the tow forms is as follows: In case the ending sound of substantive preceding is the open-syllable, the beginning voice of substantive following is plosive or affricate, {-h} is used genitive, in other voice {-s} is used. 5. The function of locative is showed {-e}, {-i} , {-es∂}, {-tu˘re} etc. {-i} indicates the position of time, it precedes other case in the compound form. {-es∂}, {-is∂}, {-s∂} connected afterward all at substantive as the function of locative, and their scope appears {-es∂}, {-s∂} at the open-syllable, at the close-syllable {-es∂} appears mainly. {-is∂}, {-s∂} is found the formation from terminal form {is∂, s∂} of adjective {itta}

(1) {-tu˘re}/-ruˇre~-re/ is construed about the expression of the case differently according to a preceding noun. In other words, it is used as the function of a dative case if it is connected after the followings-personal pronoun, noun of a government post's name, a person's name, human relations, etc., in other nouns it is shown as allative, and if it is preceded before demonstrative pronoun it is shown as locative. (2) {-tu˘re} forming a compound form becomes preceding element, and it is fellowed by {-n/ga/ra} etc., that's, fundamental mainly. And the modifier form of an infleted word forms grammaticized {-sindu˘re} by connecting before {-tu˘re}. (3) In connecting of a morpheme {-tu˘re} is possible to connect 「noun+ tu˘re」, 「inflected word+tu˘re」, but as the standard language {-t∂r∂} is limited by forming of 「noun + t∂r∂」, both forms are discriminated. (4) {-tu˘re} is analyzed into {ti} and {-re} In dialect form {ti} is shown to {te/ti/tu˘/t∂}, in the words of philology after the 15th century it is shown to {tu/tu˘i/tu˘/t∂/tbi}. As the letter 「矣 : t-」 was used as a sign of a word written in Chinese characters, 「此矣」 in Hyang-ga is possible to read as {idi}. {-re} is a dialect form, including {-ri/re/r∂}, as 「良 : ra」 is used as a sign of a word written in Chinese characters, 「此良」 is possible to read {ire}. (5) {docˇhira} in Japanese and {∂du˘re} in Korean are the same meaning. {-cˇhira} and {-duˇre} correspond each other phonologically. (6) {-tu˘re} is formed by connecting of {ti} meaning place and {-re} meaning direction, its function is grammaticized to locative·allative.
