The volatile components, normal hydrocarbons, organic acids, and nonvolatile fatty acids in the various parts of Luffa cylindrica(L.) Roemer(sponge-gourd) were analyzed by GC and GC/MS. More than 150 volatile components were separated and thirty seven components were identified and quantified. The contents of essential oil were 0,05%, 0.05%, and 0.08% on a dried weight base in leaves, stem, and seeds respectively. Fruit juice and sap contained 0.06% and 0.03% oil on the fresh weight base. Twenty six components of normal hydrocarbons in leaves, stem, seed, and unripe fruit were separated, identified, and quantified. The total concentrations of the hydrocarbons were 75.5㎍/g in leaf, 52.0 ㎍/g in stem, 46.6 ㎍/g in fruit juice, and 32.8 ㎍/g in seed fractions. The major hydrocarbons in leaves, stem, and fruit juice were nC_(25), nC_(27), nC_(29), and nC_(31) nC_(16) nC_(17), nC_(18), and nC_(19) were abundant in seeds mainly. The concentration of malonic acid among the five organic acids was highest in leaves, stem, and flowers. Unripe fruit contained 24.5 ㎎/g of the five organic acids and malic and citric acids were higher. The concentrations of palmitic, linoleic, and linolenic acids were higher concentration in the various parts of sponge-gourd and palmitic acid was distributed in the most parts. The concentrations of organic and fatty acids in the sap were negligible(Received November 21, 1991, accepted December 23, 1991).

The Purpose of the Study was to survey the reality of dance education in elementary school. The researcher used 508 elementary school teachers for survey. The survey questions composed of the attitude toward dance education, understanding content of dance instruction, time management, difficult area for instructing dance, facility, experience, and direction of dance education for student teachers in college and/or university. Analyzing above areas of dance education in elementary school, the researcher reached the following conclusion: 1. Ninety eight percent of the teachers recognized that dance education is necessary for elementary school. 2. Seventy one percent of the teachers replied that they don't have confidence in dance instruction because the content of dance instruction is too hard for them and they are also lacking in dance skill. 3. They preferred one hour dance instruction per week and had hard time in instructing Korean dance. 4. They wanted more video tapes for instructing dance. 5. Sixty five percent of the teachers realized that they need one or two sessions of workshop a year. Seventy seven percent of the teachers had no experience in taking dance education because they had no time and/or interests in dance education. 6. They wanted dance skill (50.8%) and instruction methods (72.6%) rather than dance theory. 7. They wanted full time dance teachers (72.6%).
