This study is conducted with the aim of redefining the university-based lifelong education support system for developmental disabled. The research method consisted of procedures in parallel with literature analysis and expert meetings. As for the contents of the study, a composition system that recognized the problems and solutions of lifelong education for the developmental disabled based on universities was primarily presented. Through this, it was suggested that universities can form an academic foundation for the establishment of a lifelong education support system for the developmental disabled along with the convergence field. In addition, a structural model related to this was presented along with the aspect that universities could develop a curriculum for lifelong education for the developmental disabled according to the school foundation. Also, a composition system was suggested that universities can develop lifelong education curriculum for people with developmental disabilities to lead the cooperation of local related organizations such as welfare centers for the disabled and lifelong education centers for the developmentally disabled. As a result of the study, it was analyzed that leadership in the university-based lifelong education support system for developmental disabled can contribute to fostering professional manpower qualifications and establishing cooperation with local related organizations in an integrated composition system.

Composition of fatty acids (FAs) in Pleurotus ostreatus were analyzed by gas chromatography and compositional changes according to cultivar, fruitbody section and developmental stage (days after primordia formation) were investigated. Major FAs in oyster mushroom were linoleic acid, oleic acid and palmitic acid. Unsaturated FAs were higher in pileus portion than upper- or lower-stipe portion. Oleic acid content was increased with developmental days but linoleic acid content was highest at $3{\sim}4$ days after primordia formation and then decreased after that. And ratio of unsaturated FAs/saturated FAs was decreased with basidiocarp maturation.

This study was conducted to investigate the developmental relationship between fatty acid composition in different lipid fractions and stearoyl-CoA desaturase (SCD) gene expression in steer muscles during growth. Twenty Hanwoo steers were used at 6, 12, 18, 24 and 30 months of age. Fatty acid composition and SCD mRNA level were analyzed. In the total lipid fraction, developmental profiles of C18:1, as the product of SCD enzyme, and SCD mRNA level were significantly increased between 6 months and 12 months of age. During this period, the percentage of C18:1 increased from 31.9% to 49.5% in the total lipid. The increased C18:1 level was maintained until 30 months of age within the range of 44.8- 49.9%. In contrast, the C18:0 composition decreased with age and this decrease was compensated by the increase of the C18:1. However, the sum of C18:0 and C18:1 was changed before and after 12-month old by a 20% increase. Unlike the C18 fatty acids, the C16 fatty acids such as C16:0 and C16:1 did not show a consistent change with age in steers' muscle. On the other hand, C18:2 proportion as a major polyunsaturated fatty acid in muscle was significantly reduced from 21.1% at 6 months of age to 4.4% at 12-months old and then this reduced level was maintained until 30 months within the range of 7.4-11.4%. As in the C18:1 composition during early stages, a 2-fold significant increase was observed in the $\Delta^9$-desaturase index of C18 fatty acid as a measure of SCD activity, but not in that of C16 fatty acid. Also, the steady-state level of SCD mRNA reached a peak at 12 months of age. Thus, the positive relationship between the C18:1 composition and the $\Delta^9$-desaturase (SCD enzyme) index of C18 fatty acid or SCD mRNA level was demonstrated during growth, but the negative relationship between the C18:2 composition and the above three indices was demonstrated at the same time, indicating that the sharp induction of SCD mRNA may be closely related to the dramatic reduction of C18:2, which is known as a suppressor of SCD gene expression during growth.

Silkworm pupae have been utilized as a food source and have high-quality proteins and fatty acids. However, studies on the nutritional composition of pupae according to their variety, developmental stage, and sex have not been conducted. In this study, the nutritional composition of four Korean silk varieties (Baegokjam, BG; Goldensilk, GS; Juhwangjam, JH; and YeonNokjam, YN) were analyzed according to developmental stage and sex. The main ingredient of the pupa was protein, and the protein levels were higher in females than in males. Fat levels were high in males and increased in YN and GS during the late stage but decreased in BG. Fiber content rapidly increased in the late stages, and the lowest content was observed in BG. The pupae contained all essential amino acids, which were detected at higher ratios in females with a high protein content. Fatty acids had a different predominance depending on the variety. Oleic acid level was high in BG, linoleic acid and linolenic acid levels were high in GS, and palmitic acid and stearic acid levels were high in JH. In the mineral analysis, zinc was dominant in BG, whereas calcium and iron levels were relatively low. Zinc level was low in GS, and calcium and magnesium levels were high in JH. Potassium, sodium, magnesium, and phosphorus levels were low in YN. The silkworm pupae showed differences in components according to their variety, sex, and developmental stage; therefore, selecting a variety suitable for its purpose is necessary.

Daytime activity services based on community care signify 'participatory integrated community care service' fused with diverse forms of community participation and care for adults with developmental disabilities after school graduation. They have the characteristics of lifelong care by life cycle in that adults with developmental disabilities 18 years and older receive daytime care and community participation programs. The purpose of this study is to examine community care based daytime activity services and to search for vitalization plans for daytime activity services that must unfold in the future for care programs that can be meaningful social participation opportunities for adults with developmental disabilities. Through literature review, we analyzed the state of daytime and social activity of adults with developmental disabilities as community care.Based on these findings, we devised ways to improve the daytime activities for the significant daytime of adults with developmental disabilities. At this, it proposed an increase of activity support vouchers, daytime activity service time expansions, expanded budget formulation for an increased number of daytime activity service subjects, expanded applications for the prioritization of the 20% of those with the most severe developmental disabilities and the composition of separate teams, and the role reinforcement of support centers for people with developmental disabilities.

Seasonal variations in the profile and concentrations of essential oil in Zanthoxylum piperitum were investigated by gas chromatography-mass spectrometry. Seasonal changes in the percentages of the main constituents of the essential oil of both leaves and fruits from Z. piperitum varied. Variations in essential oil yield and the amount of monoterpenes and sesquiterpenes in leaves and fruits at different developmental stages were significant. The characteristic content of essential oil in leaves was determined mainly due to the content of monoterpenes, and that in fruits was determined largely due to the sesquiterpenes. Twenty-nine compounds in the oil from Z. piperitum leaves were detected; the major compounds were ${\beta}$-phellandrene (26.90%), citronella (15.32%), ${\beta}$-myrcene (3.24%), ${\alpha}$-pinene (2.79%), trans-caryophyllene (2.66%), and fanesyl acetate (2.30%). The highest yield of oil (43.89%) in Z. piperitum leaves was obtained in May but decreased gradually beginning in June. The yield of essential oil from Z. piperitum leaves during early periods was higher than that during later periods and usually decreased from early maturation stages to subsequent stages. However, in contrast to leaves, the oil yield in Z. piperitum fruit increased in June, and oil yield later in the season was higher than that earlier in the season. These results indicate that the essential oil produced from Z. piperitum leaves at the early developmental stages was stored in leaves, and might be transferred to fruit at the final developmental stages.

To study the composition of the developmental stages of Maurolicus japonicus eggs distributed in the western Korea Strait, we investigated the water temperature, salinity, eggs and larvae in December 2002. The Korea Strait Bottom Cold Water (KSBCW) lower than $10^{\circ}C$ was found in off the Ulsan and Busan where M. japonicus eggs were the most abundant. The composition of the developmental stages of M. japonicus eggs at each station were composed of 37.7~89.5% in the first stage, 8.5~37.8% in the middle stage and 0.0~24.7% in the last stage respectively. In the southern area where the KSBCW appeared, the first stage eggs occupied 73.3~89.5%. The high percentage of the first stage eggs indicated that the eggs should be transported by the cold water lower than $10^{\circ}C$ from the Ulleung Basin in the East Sea. In the northern area where the KSBCW was not found, the first, middle and last stage eggs were composed of 37.5%, 37.8% and 24.7% respectively. The ratios of middle and last stage eggs were much higher than those in the southern area with the KSBCW, which implies that the eggs are recruited into the northern area from the southern area with the KSBCW by the Tsushima Warm Current. The pre-larvae found only in the middle and northern part of the study area would be hatched during the transport of eggs from the southern area with the KSBCW by the Tsushima Warm Current.

The Ovarian developmental phases of the reproductive cycle of Rapana venosa can be classified into five successive stages by histological study: early active stage (September to February), late active stage (December to April), ripe stage (March to July), partially spawned stage (May to August), and recovery stage (June to September). To understand the characteristics of nutrient storage and utilization in the digestive gland cells with ovarian developmental phases, we examined the digestive gland - which is the major nutrient supply organ associated with ovarian development of the female purple shell - by biochemical methods. Total protein contents in the digestive gland tissues increased in March (late active stage) and reached the maximum in May (ripe and partially spawned stages), and then their levels sharply decreased in July (partially spawned and recovery stages). Total lipid contents in the digestive gland tissues reached the maximum in January (early active stage). Thereafter, their levels rapidly decreased from May (ripe and partially spawned stages) and reached a minimum in July (partially spawned and recovery stages). The total DNA contents did not significantly change regardless of the different developmental stages of the ovary. However, it was also found from biochemical analysis that changes in total RNA content follow the same seasonal cycling to protein. These results indicate that the digestive gland is an important energy storage and supply organ in purple shells, and that the nutrient contents of the digestive gland change in response to gonadal energy needs.
