Chemical composition was determined to evaluate the quality of Panel ginseng-leaf tea over green teas. Ginseng-leaf tea was shown to contain higher contents of soluble matter, ascorbic acid and lower contents of tannins, as compared to tea leaves. The profiles of ginsenoside and sugar of ginseng-leaf tea were noticeably different from those of ginseng roots and the sample maintained high levels of these components under the manufacturing process. Total unsaturated fatty acids and free amino acids were estimated to be decreased in ginseng-leaf tea as compared to those of ginseng leaves. The compositions of amino acids and minerals in ginseng-leaf tea were similar to those of tea leaves and glutamic acid, aspartic acid, leucine, calcium, potassium, sodium, and copper were found to be major components.

One hundred and twenty indigenous pigeons of either sexes of different age groups were sacrificed in different seasons to assess the interactions of sex, age and seasons on the proximate composition and gross energy values of fresh boneless meat. The dry matter and protein contents decreased but the fat, ash and energy contents increased linearly as the birds aged. Seasons and age had significant influences on either of these two performance traits. Meat of growing pigeons of both sexes was found to contain high protein and low fat throughout the year.

This paper shows the reconstruction of existing composition chord program using back propagation neural network. In this approach, in order to produce the expectation values, weight values are controlled by neural network which rued chord pattern as a input vector. Experimental results showed that proposed approach is superior to a popular chord pattern method rather than existing composition program.

This study is about the way of music composition which is based on S/W system and also shows the skill of moving image edit for using the composed music. The result of this contents informs the mixture of a composed music by the Midi program and a moving image for using by the S/W system, also guides many students that the Computer Music Composition and Image Edit is not a difficult sphere. It is not only a main subject but also a main goal of this study.

In this study, we determined lipid content, total fatty acid composition, trans fatty acid(tFA) content, and acid value of twenty black-bean-sauce noodles collected in Seoul city area. Total lipid contents of twenty samples were determined to be 3.33~9.23% on wet base. Total unsaturated fatty acids were from 47.83% to 83.18%(mainly oleic and linoleic acid). Total saturated fatty acids ranged from 16.06% to 51.48%. Besides, tFA contents in total lipid of samples were ranged from 0.38% to 1.39%, equivalent to 20 to 80mg per 100g of black-bean-sauce noodles. Acid values of lipids extracted from samples ranged from 0.56 to 2.88.

The purpose of this study is to understand changes of the population and family composition in apartment houses. The main contents of this study is to find the way of housing planning through the analysis of the population and family composition by the unit types. The population and family composition were studied by computer data base program to 11,000 residents of selection 4 apartments houses. The structure of the family types proved to be constant by the result of analyzing the 10 family types. If the family types of certain resident's groups are given, this study will be able to estimate population structure to them. The transition of the population and the family composition changes to the unit types proved to be constant by the time. The distribution of manhood and matured children is tend to change according to how large the size of house is, and to change the structure of family composition.

The purpose of this study is to provide basic data and guideline to STEM(Science, Technology, Engineering, Mathematics) educators who prepare engineering education in elementary and secondary school. For this, this study develops a composition model for engineering education program of elementary and secondary school. To do this, a literature research, experts interview and Delphi survey were conducted. Through the literature research, we extracted the components of model for engineering education program of elementary and secondary school and then made a first draft of the model. The draft was revised by experts while Delphi survey was used to validate the model based on Delphi panels' opinions. The panels for the Delphi survey consisted of 51 experts in the STEM education field. The survey was conducted three different times and importance survey was included in the third stage. The conclusions of this study were as follows: First, the model consist of definition, 4 directions, 4 characteristics, 3 educational goals according to school level, educational contents area and element, teaching and learning method and evaluation method. The educational contents area and element consist of 2 major areas, 7 areas and 18 elements. Second, all components of the developed model were valid in most of the statistics such as mean, standard deviation, the degree of consensus and convergence, and CVR(Content Validity Ratio). Third, importance for education contents area and element according to the school level are analyzed.

This study was designed to elucidate the lipid contents, neutral lipids components and fatty acid composition in fresh shellfishes, produced in Korea. Four kinds of shellfishes including sea mussel, short-necked clam, corb shell and and ark shell were selected according to the higher sales order and cheaper retail price at fish markets in Seoul in July 1985. The results abtained were as follows; 1. The average total lipid contents in four shellfishes were 2.3% by wet weight basis. The ratios of neutrial lipid, glycolipid and phospholipid in the total lipid were 51.1 : 4.9 : 44.0 in sea mussel, 66.0 : 3.2 : 30.8 in ark shell, 37.8 : 2.2 : 60.0 in short-necked clam and 54.5 : 2.0 : 53.5 in corb shell, 2. The average value of acid value, iodine value and unsaponifiables contents of total lipids were 1.3, 217.8, 92.0 and 20.3%, respectively. 3. The composition of the neutral lipids were triglycerides, esterified fatty acids, sterylesters, free sterols and monoglycerides in four shellfishes. 4. The major fatty acid composition of total lipids were palmitic, eicosapentaenoic, docosahexaenoic and palmitoleic acids in four shellfishes. The average total unsaturated fatty acids of total lipid were 64.5%, and $\omega$-3 highly unsaturated fatty acids were 27.0%. The average p/s Ratiio were 1.3.

The research studied the nutritional composition and health effects of the Giwongo with its efficacy in providing nourishment to blood, liver and kidney as well as being an aid to the mental stability. The Giwongo is made by boiling the same amounts of Lycium fructus and Longanae arillus. Giwongo was analyzed to measure proximate nutritional composition, mineral contents, free sugar content and polyphenol compound content. The DPPH scavenging activity and its antioxidative effectiveness were also analyzed. Giwongo was composed of 16.7% water, 4.9% crude protein, 3.7% crude fat, 3.8%, crude ash 70.9% carbohydrate with the content per 100 g of 336.5 kcal. The Giwongo mineral contents were potassium, sodium and calcium in sequence according to contents. Per 100 g Giwongo were found 9.62 g glucose, 4.67 g fructose and 18.00 g sugar. The Giwongo had 60.67% DPPH electron donating ability and $32.19^{\circ}Brix$. The Giwongo made of Lycium fructus and Longanae arillus had effectiveness of tonify the liver and kidney, nourish blood, and psychologic stability. As such Giwongo may help prevent the symptoms of unbalanced health due to excessive stress and unhealthy diet.

an analysis of stomach contents of skipjack tuna Katsuwonus pelamis and plankton samples collected during troll fishing operations showed that the abundance of some dominant organisms in tuna stomachs was related to their abundance in the plankton. Fish larvae mainly pilchards, Nyctiphanes australis, brachyuran and other decapod larvae and calanoid copepods are important food item for skipjack. The copepods Undinula vulgaris and Nannocalanus minor occurred consistently throughout the survey period in both stomach contents and plankton samples. U. vulgaris appeared to be a preferred food considering its high percentage composition in tuna stomachs compared with its low percentage composition in the plankton. Temora turbinata and N. minor may also serve as important food items for skipjack. The largest catches of the fish were made in January and February when plankton organisms were composed dominantly of N. australis, copepods and brachyuran larvae. The main stomach contents during this period were N. australis and brachyuran larvae.
