The volatile aroma components were isolated from Korean flue-cured tobacco (N.C. 2326) by using a vacuum steam distillation method. Individual aroma components were identified by GCIMS and comparison of gas chromatowaphic retention time with those of the authentic samples. Sensory analysis showed that a vacuum steam-distilled product of Flue-cured tobacco had a typical haylike, floral and fruity aroma. Among 62 compounds identified, major compounds included neophytadiene, benzyl alcohol, ethyl acetate, phenyl ethyl alcohol, ethyl alcohol, ethyl formate, acetic acid, solanone, 2-acetyl pyrrole, $\beta$-ionone epoxide, 2, 4-heptadienal (2 isomers), megastigmatrienone (4 isomers), furfural and total amounts of 13 compounds were about 80%.

The volitile compounds Produced from the Maillard reaction of D-glucose and DL-alanine or DL-$\alpha$-aminobutyric acid using water or propylene glycol as a reaction amdeum were analysed by gas chromatofiraphy and mass spectrometry. From two kinds of reaction products in water 18 compounds were identified. The major compounds in a reaction product of glucose with alanine were 5-hydroxy methyl-2-furfural, 2-acetyl pyrrole and 2-formyl-5-methyl pyrrole, and those in a reaction product of glucose with $\alpha$-aminobutyric acid were 2-ethyl crotonaldehyde and 2-methyl-3, 5-dihydroxy-4H-pyran-4-one including the above 3 compounds. From two kinds of reaction products in propylene glycol solution, 35 compounds were identified. The major compounds in a reaction product of glucose with alanine were alkyl pyraainef, 2-methyl furfuryl alcohol and 2-acetyl pyrrole, and those in a reaction product of glucose with $\alpha$-aminobutyric acid were propionaldehyde PGA, 2-ehtyl crotonaldehyde, 2-acetyl pyrrole and 2-acetyl-5-ethyl furan.

The volatile oils of apricot(Prunus armeniaca var. ansu Max.) and Japanese apricot (Prunus mume Sieb. et Zucc.) were isolated by stem distillation-extraction. The resulting oils were analyzed by GC and GC-MS. A total of 80 components were identified in apricot, including 9 naphthalene derivatives of which had not been previously reported in apricot volatiles and 72 components were identified in Japanese apricot, The major components in apricot were n-hexanal(4.18% of total oil), traps-2-hexenal(11.57%), n-hexanol(14.38%), traps-2-hexen-1-ol(8.28%), cis-3-hexen-1-ol(2.60%) , linalool (12.61 %), α-terpineol (5.63%), geraniol (2.78%), trimethyltetra-hydronaphthalene derivatives(7.51%) and tetradecanoic acid(3.67%), while benzaldehyde(62.40%), terpinen-4-o1(3.97%), benzyl alcohol (3.97%) and hexadecanoic acid (4.55%) were major components in Japanese apricot. However, the characteristic aroma of apricot appeared to be due to combination of C_6 aldehyde and alcohols, terpene alcohols, lactones and β-ionone-related components and that of Japanese apricot could be due to the presence of benzaldehyde and benzyl alcohol.

Objective: The object of the this study was to understand the Mongolian oral health habit on Mongolian people, can be gotan important informations for oral health education or oral health program to establish proper oral health policy forMongolian people. Methods: In this study, people of the selected age groups from three regions of Mongolia were surveyed during the stipulatedperiod of time and oral examination was performed according to the standardized method recommended by the WorldHealth Organization. From the entire Mongolian population, about 0.04% (1,289 people) of people were surveyed. Results: The frequency of daily average intake of sweets was 1.65±1.20 and there was a marginal difference between genders(p>0.05). Location-based results showed that of the three locations studied; Ulaanbaatar (1.53±1.22), Bornuur(1.64±0.99), and Gobi (2.04±1.38), Gobi inhabitants had the highest frequency of daily intake of sweets (p<0.05). The frequencyof toothbrushing on a daily basis was 1.79±0.90; 1.78±0.98 for men and 1.80±0.86 for women, which indicates avery marginal difference between the two genders (p>0.05). Overall, 76.0% of people performed toothbrushing prior tobreakfast, followed by 47.9% of people who performed toothbrushing prior to sleeping. Also, 92.1% of people stated thatthey possessed a toothbrush and toothpaste. Conclusion: It is necessary to encourage the people of Mongolia to increase the frequency of daily toothbrushing by performingtoothbrushing after meals as well as before sleeping.

The volatile oils of the fresh leaf and seed of parsley(Petroselinum crispum) were isolated by simultaneous steam distillation and extraction procedure. The compositions of the resulting oils were investigated by gas chromatography and gas chromatography-mass spectrometry. The volatile oil contents of leaf and seed were 0.06 % and 3.11 %, respectively. Fifty-eight components including 15 partially characterized components were identified in leaf oil and 23 components in seed oil. Seven of them are suggested as new parsley leaf volatiles. Terpenoids were represented as much as 46.4 % of total leaf volatiles and 49.3 % of total seed volatiles. The leaf volatiles contained a lot of myrcene(3.02 %), 4-isopropenyl-1-methyl benzene(4.52%) and p-1,3,8-menthatriene(10.49 %), but the seed volatiles were characterized by greater quantities of the isomers, α-pinene(22.28 % ) and β-pinene(16.20 %), although these compounds were contained only trace in leaf volatiles. Of the components identified in both oils, the most abundant component was myristicin, constituting 21.80 % of the leaf volatiles and 47.54 % of the seed volatiles(Received January 4, 1990, Accepted February 22, 1990).

교정학과 교육학은 목적, 주요내용과 교육대상, 접근 방법 등에서 학문으로서의 비슷한 면도 있고 관련성이 상당히 있다. 또 한편 두 학문을 직접 비교할 수 없는 다른 점들도 있다. 본고에서는 두 학문의 개념적 접근과 주요내용 중에서 상대성이 있다고 생각되는 부문을 제한하여 비교하여 제시 해보고자 한다. 먼저 본인이 교육학적 배경지식이 교정학보다는 익숙한 편이므로 교육학적인 관점에서 내용을 먼저 정리하여보고 이와 관련된 교정학의 개념, 교정에서의 교육적 관련성을 정리하려고 노력하였다. 그러나 교정학의 깊이있는 내용에 대한 학문적 배경이나 지식, 경험이 부족하여 전반적인 내용과 깊이있는 비교가 부족하지만 정리한 내용을 아래와 같이 제시하고자 한다.
