  • The in situ nylon bag degradation and in vitro intestinal digestibility of dry matter (DM), and crude protein (CP) of mulberry (Morus alba) plant fractions was studied at four harvest stages, 3 (W3), 5 (W5), 7 (W7) and 9 (W9) weeks. Degradability of DM and CP of the whole plant and stem fractions declined significantly (p<0.01) with advancing plant maturity in the order W3>W5 and W7>W9 and W3>W5>W7>W9, respectively. The degradation of DM and CP of the leaf fraction was also influenced by plant maturity but no trend was observed. The degradation of DM and CP of the whole plant and leaves increased rapidly during the first 48 and 24 h of incubation, respectively, when maximum degradation was reached. In vitro intestinal digestibility of CP was more influenced by the residence time in the rumen than by plant maturity. This study showed that mulberry is suitable as a supplement, particularly to low-quality roughages, in providing a source of rapidly available nitrogen to the rumen microbes, hence improving the roughage degradability and intake.

  • In this study, the acoustic response technique was applied to evaluate the maturity of melon nondestructively. The acoustic response signals through melon were obtained by microphone and signal conditioner with the lapse of days after fruit set. The acoustic parameters such as resonant frequencies and the spectrum energy ratio were analyzed. To investigate the relation between acoustic parameters and firmness of melon, the compression test was performed. Three resonant frequencies representing f1, f2 and f3 were 150 to 250 Hz, 300 to 400 Hz, and 450 to 550 Hz, respectively. The resonant frequencies were shifted to the lower frequencies and the magnitude of spectrum decreased as the maturity of melon increased. Some significant correlations were found between melon firmness and the spectrum energy ratio in some frequency ranges. It is possible to estimate the maturity of melon by acoustic response technique.

  • Evaluation of climate change on the rice productivity was conducted using crop growth simulation model, where Odae, Hwaseong, Ilpum were used as a representative cultivar of early, medium, and medium-late rice maturity type, respectively, and climate change scenario 'A1B' was applied to weather data for future climate change at 57sites. When cropping season was fixed, rice yield decreased by 4~35% as climate change which was caused by poor filled grain ratio with high temperature and low irradiation during grain-filling. When cropping season was changed, rice yield decreased by only 0~5% as climate change which was caused poor filled grain ratio with low irradiation during grain-filling period. However, this irradiation decline was less than when cropping season was fixed. Therefore, we need to develop rice cultivars resistant to low irradiation which can maintain high filled grain ratio under poor irradiation condition, and late maturity rice cultivars whose growing period is longer than the present medium-late maturity type.

  • The technical proposal suggested and published by MIC(Ministry of Information and Communication, henceforth MIC) contains too general assessment elements, which causes qualitative and subjective assessment of technical proposals. Thus, in terms of the technical proposal assessment. It lacks In fairness, validity and accuracy. Furthermore, it has a great deal of difficulty in assessment caused by the inconsistency between proposal planning and assessment methods. Also, each company has different writing format, so it is impossible to make use of its maneuvering data for the assessment. To overcome these weaknesses, our research focused on a quantitative evaluation on development organization, which is a part of organizational and administrative part of the technical proposal suggested and published by MIC. In this research, we divided development organization for the technical proposal into organization, teams, and team members, and then studied addition, deletion and merging for the assessment criteria. For the related study, we chose especially CMM(Capability Maturity Model) from a lot of international and national references, which is a model measuring the maturity of organization, and then we focused on Small-CMM which is available in the small-sized organization. We also suggested input form, description method, assessment elements for the quantitative assessment in the chosen developmental organization, and finally we proposed standard referencing criteria for the assessment. Our study concludes that our assessment method are valid and available in comparison with the previous Delphi method through a validity evaluation test.

  • In clinical orthodontics, it is significant to understand the stage of growth in a growing patient. In order to assess the skeletal maturity of the patients, the hand-wrist radiograph and the cervical vertebrae (Cervical Vertebrae Maturation Indicators : CVMI) was evaluated from the lateral cephalograph and the skeletal maturity determined from the hand-wrist X-ray (Skeletal Maurity Indicators : SMI) taken on the same day in the same patients, and its interrelationship examined to come up with the following results: 1. The skeletal maturity evaluated from the hand-wrist radiograph and the maturation of the cervical vertebrae from the lateral cephalograph showed a significant interrelationship with each other. 2. In the evaluation of the skeletal maturity using the SMI and CVMI, the CVMI 1 showed a siginificant correlation with SMI 1, 2, the CVMI 2 with SMI 3, 4, CVMI 3 with SMI 6, 7, CVMI 4 with SMI 7, 8, CVMI 5 with 9, 10 and CVMI 6 with SMI 11. 3. When the morphological changes in the 2nd and 3rd cervical vertebrae were separately observed, it was seldom that the concavity appeared in the lower border of the 2nd cervical vertebra and at the same time not appear in the 3rd cervical vertebra (CVMI 2 : 10.38%, CVMI 3 : 6.56%) 4. In each of the skeletal maturation stage evaluated from the hand-wrist and the cervical vertebra, the average age and its standard deviation in male and female patients appeared to have large differences among individuals. Skeletal maturation seemed to appear earlier for the girls than for the boys, and its termination 24 months faster for girls.

  • The objective of study was to evaluate the apropriate maturity indices for garbage composting using sawdust as bulking agent. Materials used in this study were the average composition garbage(G20) and garbage conditioned by sawdust(GS30, GS50) and cereals(GSC30). Indices for evaluating maturity were VS, water soluble TOC, polysaccharide, Humification Index(HI), and E4/E6. Experiment results showed that VS reduction was the most desirable index for evaluating compost maturity except for the GS50 which were conditioned with high sawdust Water soluble TOC decreased rapidly during the composting of first one month and then little changed. Therefore, water soluble TOC was recommended as maturity index. Polysaccharide was considered as a maturity index in case of garbage conditioned with sawdust and high cereals. Humification Index(HI) and E4/E6 were available as maturity indices in case of only some garbage composting so additional study was needed to confirm them as maturity indices for all garbage composting. Correlation analysis indicated that indices for evaluating maturity of garbage(about 30 C/N ratio) adding sawdust as bulking agent and high cereals, were VS reduction, water soluble TOC, polysaccharide, and E4/E6.

  • This study was investigated the herbage productivity and nutrient contents of corn (Suweon 19 and Kwanganok) and sweet sorghum (Ramiki sorgo and Silage sorgo) at the stage of maturity (10-DBS, silking, milky and dough stages) to identify the utility value of sweet sorghum as a substituting crop for corn. The silage materials (dough stage) were chopped and were storaged for 90 days in polyethlene bag with O.lmm thickness. Chemical composition, nitrogen content and in vitm dry matter digestibility were evaluated. Also, daily intake and palatability were checked in the feeding trial with four male sheep in average weight about 57kg. Both fresh and dry matter yield of corn and sweet sorghum were increased as the maturity processed (P< 0.05), and sweet sorghum showed higher total yield potential than corn. Crude protein content of the cultivars was decreased as the maturity was processed (P< 0.05). Neutral detergent fiber (NDF) content of the cultivars, in general, showed highest at silking stage, followed by 10 days before silking (10-DBS), and milky and dough stages (Pi0.05) in order. Acid detergent fiber (ADF) content was increased as the maturity processed, and it showed the highest value at milk stage. However, the contents of ADF in sorghum plant was decreased during the late maturity. Crude protein content of the silage was not significantly different among cultivars used, while NDF content was highest in Ramiki sorgo, followed by Silage sorgo, Kwanganok and Suweon 19. In v i m DM digestibility of the silage was highest in Kwanganok, followed by Suweon 19, Silage sorgo and Ramiki sorgo. Total N content of the silage was highest in Ramiki sorgo, followed by Suweon 19, Silage sorgo and Kwanganok. DM intake of the silage was highest in Ramiki sorgo, followed by Suweon 19, Silage sorgo and Kwanganok and it was closely related to the palatability value.

  • As a result of the study, it was found that social support affects career maturity. It was confirmed that in order to increase the career maturity of junior college students, it is necessary to understand the interpersonal relationship including information and evaluation of the student environment, effective support, and emotional interest, and it is necessary to find a way to perceive high social support. In the effect of social support on career maturity, career decision self-efficacy was found to have a partial mediating effect. Instructors should support students who have anxiety about their uncertain future so that they can increase their self-esteem and self-efficacy so that they can enhance their career maturity.

  • The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.
