“한꺼번에 많은 선박이 움직일 텐데 레이더 잘 확인하시고 주의하십시오” “네 감사합니다. 수고하세요” 6월 19일 오후 1시 무렵 인천해상교통관제센터 6층 관제실은 항행 중인 선박들과 한국어와 영어로 무선교신이 한창이다. 마침 시정주의보가 해제돼 정박지에 대기 중이던 많은 선박들이 항만에 순서대로 입항하고 있었다. 관제실 모니터에는 이들 선박을 가리키는 노란색 세모꼴 표시가 두드러졌다. 인천 연안부두 월미도에 있는 인천 VTS센터에서 홍석인 관제사를 만나 인터뷰했다. 홍 관제사는 한국해양대학교 항해과를 졸업하고 3년간 승선한 후 2006년부터 해상교통관제사로 일하고 있다.

홍석 慶南大學校 附設 基礎科學硏究所 1994 硏究論文集 Vol.6 No.-

The experiments of photolyses of griseofulvin in the presence of alkanethiols such as ethanethiol, butanethiol and cyclohexanethiol were carried out under the same conditions with nitrogen gas flow by use of 200W high pressure mercury lamp jointed Pyrex glass filter at room temperature. The chemical reactions did not occurred without irradiation for the same time. while on irradiating for 3 hours, the reaction solutions looked like yellowish. Finally, addition products of alkanethiols to 3'-position of griseofulvin were mainly obtained after prolonged irradiation for 11 hours. It was found that the bulkier are alkyl groups, the slower are the rates of photoadditions.

산화 카보닐의 이민에 대한 [3+2] 고리첨가반응의 치환기효과와 AM1 계산에 의한 생성열 : Theoretical Approach to their Substituent Effects

Cycloadditions of carbonyl oxides to imines with one or two of substituents such as methyl, ethyl, isopropyl, t-butyl, phenyl and benzyl groups were performed to be 1,2,4-dioxazolidine(3). Heats of formaton of the starting structures and resulting structures were calculated after optimization to gradient 0.1 kcal mol^(-1) A^(-1) at the AM1 level. Their heats of formation were different according to the anti or syn configuraton of a carbonyl oxide and an imine. Anti-anti combination gave higher exothermic energy than syn-syn configuration. The most exothermic of anti-anti combinated cycloaddition structures is 3j with ethyl group at the 3-position of 3 obtained from cycloaddtion of anti acetaldehyde-O-oxide to anti benzaldimine, while the least exothermic of syn-syn combined cycloaddition structures is 3o with cis phenyl group at the 3-position to methyl group at the 5-position and trans methyl group at the 4 position of 3 produced from syn acetaldehyde-O-oxide and N-methyl benzaldimine.

Substituent effect and orientation in the nitration of the alpha-substituted toluene derivatives with electron-withdrawing group such as chlorine, cyano, methoxycarbonyl, nitro and trimethylammonium were predicted by semi-empirical method at PM3 level. Ortho, meta and para-directing trends were estimated from the interaction of their FMOs, heats of formation and net charges. The results by the semi-empirical method were in approximate agreement with their corresponding known experimental yields.

클로르프로마진 유도체의 핵산염기에 대한 광화학 반응성과 반경험적 에너지 계산

Semi-empirical calculations have been performed by PM3 method in order to understand energetically the reactions of chlorpromazine analogs to the purine ribonucleotides and deoxyibonucleotides and modified 9-methylpurine bases. Large energy differences were not found among the HOMO's and LUMO's of phenothiazine derivartives. Both chlorpromazine and 2-Chlore- N-methylphenothiazine had similar frontier orbital energies each other. The energies of binding, gradient, and heat of formation before and after promazyl bonding to each purine base were also obtained. Finally, energy differences between the corresponding compounds gave relatively different reactivities among the bases. In the reaction of promazyl moiety with 9-methylpurine, the reactivity predicted from the binding energy and △H?? showed a tendency to decrease in order of guanine, adenine, 1-methylhypoxanthine. 1-methylguanine and hypoxanthine

中氣의 病因病機 및 治療에 관한 文獻考察

홍석,이동원,전홍열 대한한방신경정신과학회 2000 동의신경정신과학회지 Vol.11 No.1

Object: Show the treatment about Jungkijeung(Zhongqizbeng) by distinguishing Apoplexy(Zhongfeng), yujungfung(Leizhongfeng), gualjung(Juezheng), and observation of cause, process, quality. Method: Researched definition, cause, process, treatment and herb med through chinese & korean medical publication refered to Jungkijeung(Zhongqizheng) Result: 1. Jungkijeung(Zhongqizheng) is simmilar to Apoplexy(Zhongfeng) that spiritual shock occurred to syncope, dysarthria, trismus, quadriplegia. But the symptom of Jungkijeung(Zhongqizheng) is coldness, no-sputum, sink-pluse; that of Apoplexy(Zhongfeng) is warmness, much secretion, float-pulse. 2. Jungkijeung(Zhongqizheng) is mainly caused by the serious anger and the reverse movement of spints by the seven emotional factor. The process of Jungkijeung(Zhongqizheng) are "Fire and Fever(huore)" "Weatness and sputum(shitan)", and most importantly "Weakness of vital-qi(qixi)" 3. The treatment of Jungkijeung(Zhongqizheng) is adjustment and circulation of jiao. In early stage, don't use of Apoplexial-Med. 4. As following herb-med are used for Jungkijeung(Zhongqizheng). Sohaphang-won(Suhexiangyan) is 18 times; Palmisungi-san(Baweishunqisan) is 13 times; kang-tang(Jiangtang) is 8 times; Mokhyangsungi-san(Muxiangshunqisan) is 6 times. 5. Atractylodes macrocephala KOIDZ(Baishu) is used for 40 times most frequently, Saussurea lappa CLARKE(Muxiang), Cyperus rotundus L (Xiangfuzi), Citrus unshiu MARCOR(Chenpi), Glycyrrhiza uralensis FISCH(Gancao), poria cocos WOLF (Furing), Panax ginseng NESS (Renshen) etc are orderly used. 6. Acupoints same as GV20(Baihui), L14(Hegu), Liv2(Xubgjian), 12 Junghyul(Jingxue) is used for acupunture. And CV8(Shenque), CV4(Guanyan) is used for moxibustion. Conclusion: As Jungkijeung(Zhongqizheng) is differed from Apoplexy(Zhongfeng), yujungfung(Leizhongfeng), gualjung(Juezheng), we must also cure Jungkijeung(Zhongqizheng) to the other disease. It is need to distinguishment Jungkijeung(Zhongqizheng) from neurotic psychotic disease, though similar to conversation neurosis.

2-머캅토싸이아졸 및 2-하이드록시싸이아졸류의 토오머화와 분해 가능성 : degradation ability

홍석 경남대학교 환경문제연구소 2003 환경연구 Vol.26 No.-

Stability of tautomers of 2-mercaptothiazole and 2-hydroxythiazole was investigated with reaction energies calculated by density functional theory in other to predict degradation of a kind of benzothiazoles such as 2-mercaptobenzothiazole and 2-hydroxybenzothiazole. Single point geometric structures have been established for the starting material structure, homodimer (or heterodimer) and products as tautomers. The result was that thiazoline-2-thione, a tautomer, was energetically more stable than the corresponding thiol as known generally. It was expected that their high stabilities were not always in agreement with their poor degradation because of the catalytic factors such as naturally occurring acid, base, metallic ions and so on.

Theoretical calculations were performed for the parameters on the formation of benzil hydrazone derivatives, their predicted intermediate structures, isomers, photorearrangement and cycloaddition by the semiempirical method such as PM3, ZINDO/S. Differences in their total energies before and after forming benzil hydrazone derivatives were exothermically negative. In the case of isomerization of benzil hydrazones to their enolic azo or ketyl azo compounds, ketyl azotization is more preferable. Intramolecular cyclization of each benzil hydrazone at the ortho-phenyl position with internal NH nitrogen and with ortho-position carbon of the other phenyl group would be possible at the level of overlapping on the specific place of its frontier orbital(HOMO) in the first excited state except for benzil 2,4-dinitrophenylhydrazone.
