  • Normal- and late-harvested Fuji apples were fermented using the rapid-fermenting yeast strain Saccharomyces cerevisiae SS89. The late-harvest apples showed a slightly higher soluble-solid content with a lower level of total-acid and moisture (p<0.05) contents as well as hardness (p<0.05) than the normal-harvest apples. During the fermentation, the apples had similar changes in the pH and total-acid content regardless of the harvest time, but the increases in the alcohol content and yeast viable count with the decrease of the soluble-solid content were more rapid in the late-harvest apples than in the normal-harvest apples. After the completion of the fermentation, the soluble-solid and alcohol contents became very similar. The late-harvest cider showed a high total phenolic-compound content and a high DPPH radical scavenging effect, although these were slightly lower than those of the normal-harvest cider. It also showed a higher malic-acid content and higher hue color (p<0.05), Hunter's L, and b (p<0.05) values than the normal-harvest cider. In the sensory evaluation, the late-harvest cider obtained a higher score in taste and a lower score in color compared to the normal-harvest cider.

  • Forage oat (Avena sativa L.) is grown extensively in a double-cropping system on dairy farms. Four oat varieties ('Swan', 'Targa', 'Foothill', and 'Nugene') were evaluated for forage production and forage quality during two growing seasons (spring and autumn) at two locations (central and southern region) in South Korea. The heading stage of four oat varieties was observed during spring, but the autumn season did not produce heading until harvest time except for the 'Swan' variety (early-maturing variety). The heading stage of 'Swan' in both locations was earlier compared to other varieties. The four varieties were resistant to both foliar disease and insects. Lodging resistance was higher during autumn except in 2002 at the central region, and late-maturing varieties ('Foothill' and 'Nugene') have lower lodging resistance. Dry matter (DM) content was significantly different between varieties (p<0.001). Comparing different varieties, 'Swan', an early-maturing variety, was highest in DM content. In DM, total digestible nutrients (TDN) and crude protein (CP) yield, the yield of oat varieties in the southern region was higher than in the central region, and forage yield of the oat varieties in the spring season was higher than during the autumn season. The DM and TDN yield showed significant differences between oat varieties. The CP content of oats grown in the central region (Cheonan) was lower than oats grown in the southern region (Daegu), and the spring season produced oats with lower CP compared to the autumn season. Among the four oat varieties, the CP content of late-maturing varieties was higher than the Swan variety (early-maturing variety). The acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents were higher for the varieties grown in Cheonan and during the spring season. The ADF and NDF contents of late-maturing varieties were lower than the early-maturing variety. TDN and relative feed value (RFV) were higher for the varieties grown in Daegu and during the autumn season. Late-maturing variety had higher TDN and RFV than early-maturing variety. Our study showed differences in forage production and forage quality of oats grown in different locations, seasons and varieties. Forage quality as well as forage production was better in the southern region than in the central region. Forage quality was better during autumn, but forage production was better during spring. Late-maturing variety had better forage quality than the early-maturing variety. Therefore, late-maturing varieties are more suitable for use in the southern region.

  • Kiho Academic in the late Joseon Korea, the negative effect of the Horak debate is amplified and the division within the academic is accelerated. However, the scholars of the Kiho Academic field put forth efforts to unify the academics with the same sense of responsibility to end the schism. Nevertheless, the scholars of the Kiho Academic have shown various differences in the process of accepting Neo-Confucianism, which creates new schools. Therefore, Kiho Academic in the late Joseon Korea coexisted with various schools with different academy positions. Some of the representative groups are Hwaseo, Nosa, Ganjae, Yeonjae, and Uuidang Schools. In addition, through the scholarly differentiation and the school division of the Kiho Academic, the debate on the mind that characterizes Neo-Confucianism of the late Joseon Korea has developed. However, there was a common value that everyone pursued in the middle of the debate: the construction of a moral ideal society, the ultimate goal of Neo-Confucianism. In conclusion, though the purpose they pursued was not fulfilled, it can be seen from the debate on the mind that they fiercely demanded that these requests were urgent in the late Joseon Korea This paper, therefore, the situation of the Kiho academic in the late of Joseon Korea, the problem consciousness of the scholars of the Kiho academic, and the issue and development of debate on the mind.

  • A total of 168 seven days-old Arbor Acres chicks were reared in late-autumn on 4 types of litters; sawdust, rice husk, sugarcane bagasse or wheat straw up to 49 days of age to compare the growth performance, evaluate the manureal value and Coccidial oocyst population in used litter. Sadust, rice husk, sugarcane bagasse and wheat straw did not differ statistically for live weight, feed consumption, feed conversion ratio and survivability (p>0.05). However, live weight and survivability tended to increase on sawdust. The highest moisture content of used litter was found in sugarcane bagasse followed by sawdust, rice husk and wheat straw (p<0.05). Rice husk contained the highest amount of of nitrogen, phosphurus and potassium followed by sawdust, sugarcane bagasse and wheat straw (p<0.01). Oocyst content of all treatment groups increased suddenly up to 5 weeks of age and thereafter suddenly declined up to 7 weeks of age. Litter materials did not differ at 35 and 42 days of age for oocyst content, but significantly differed at 49 days of age (p<0.01). So, the above findings reveal that sawdust may be suitable litter followed by rice husk, sugarcane bagasse and wheat straw in late-autumn in Bangladesh in respect of broiler growth performance.

  • Yield and plant constituent responses of forage sorghum cultivars have usually been compared in uniform defoliation management test. However the influence of harvest time on differential response of cultivars needs more precise definition. Therefore this study with sorghum-sorgo-sudan hybrid cv. NC+Sweet Leaf, and Super Su 22 and Sorghum-Sorghum hybrid cv. Pioneer 931 was carried out under two defoliation regimes, namely defoliation at heading stage of each variety and defoliation on the same calendar date in response to heading stage of early variety. The results are summarized as follows; 1. Three harvests were taken by early variety with 80 days and two harvests by late variety with 94 days from sowing to heading. 2. Dry matter and TDN yield tend to be higher when the plants are cut at ear emergence stage of late variety. 3. Crude protein content was similar for the same growth growth stage of 1st growth and 1st regrowth, and rather big different between varieties. 4. Considering only dry matter and TDN yield, it is recommendable to cut two times at ear emergence stage of late variety and also three times at ear emergence stage of early variety in view point of utilization period extension and distribution of forage products.

  • The effects of swirl on early flame development and late combustion characteristic were investigated using a high speed single-shot visualized 51 engine. LDV measurements were performed to get better understanding of the flow field in this combustion chamber. Spark plugs were located at half radius (R/2) and central location of bore. High speed schlieren photographs at 20,000 frames/sec were taken to visualize the detailed formation and development of the flame kernel with cylinder pressure measurements. This study showed that high swirl gave favorable effects on combustion-related performances in terms of the maximum cylinder pressure and flame growth rate regardless of spark position. However, at R/2 ignition the low swirl shown desirable effects at low engine speed gave worse performances as engine speed increased than without swirl. There were distinct signs of slow-down in flame growth during the period when the flame front expanded from 2.5mm in radius until it reached 5.0mm apparently due to the presence of ground electrode. There seemed to be heat transfer effect on the flame expansion speed which was evidenced in high swirl case by the slowdown of the late flame front presumably caused by relatively large heat loss from burned gas to wall compared with low- or no-swirl cases.

  • Effects of IPTG induction on cell growth and production of ${\beta}$-galactosidase-preS2 fusion protein (${\beta}$gal-preS2) were studied in a defined medium using a recombinant Escherichia coli JM109/pCMHB30. IPTG was added (0.2 mM) to induce the cloned-gene expression in the early-, mid-, and late-log growth phases. The most serious decreases in growth rate and plasmid stability were observed for the induction in the early-log growth phase. The expression level of ${\beta}$gal-preS2 attained by the induction in the mid-log phase was about 0.51 mg fusion protein/mg total cellular protein, which was 2- and 5-fold improvement over the levels obtained with the inductions in the early- and late-log phases. Formation of acidic byproducts including acetate and pyruvate showed different profiles during the fermentation period for each cases of induction; pyruvate was the major byproduct for the induction in the early-log phase while acetate production became more significant for the cases of inductions in the mid- and late-log phases.

  • This study examines the effects of late school-aged children's perception of their mother's responses to negative emotions and their ego resilience on their life satisfaction. Data were collected from 390 fifth- and sixth-graders residing in Kwangju, Korea. With the data, frequency, percentages, and Cronbach's ${\alpha}$ were calculated. Pearson's product moment correlation coefficients and hierarchical regression analyses were also considered. The effects of various variables on life satisfaction were analyzed, and according to the results, vitality had the greatest effect on life satisfaction, followed by vitality, optimism, emotional coaching responses, interpersonal relationships, emotion-reducing responses, emotion control, and the material employment status, in that order. The study contributes to the literature by providing additional insights into the mother's desirable responses to children's negative emotions and highlighting the importance of positive ego resilience in children's life satisfaction through the elucidation of effects of late school-aged children's perception of their mother's responses to negative emotions and their ego resilience on their life satisfaction.

  • Controlled auto-ignition(CAI) combustion, offers the potential to improve fuel economy and reduce emission simultaneously. In this study, CAI-combustion was achieved in a single cylinder gasoline DI engine with modified camshafts in order to restrict the gas exchange process. We investigated the effects of air-fuel ratio, residual EGR rate and injection timing such as early injection and late injection on the attainable CAI combustion region. The effect of injection timings on combustion characteristic such as start of combustion, combustion duration and heat release rate was also investigated. From the result early injection causes the mixture to ignite earlier and burn more quickly due to the exothermic reaction during the recompression and gives rise to good mixing of the fuel/air. On the other hand, late injection extended the operation region more than early injection but the emissions of HC and NOx were more or less increased than early injection.

  • Objective: This study aimed to examine the effects of attachment and shared time between mother and child and self-esteem on subjective well-being in late childhood. Methods: A total of 329 fifth and sixth graders in elementary school (183 boys and 146 girls) participated in the study. They responded to questionnaires regarding attachment and shared time between mother and child and the self-esteem and subjective well-being of children. The data were analyzed using SEM. Results: Attachment and shared time between mother and child had an indirect effect through self-esteem as well as a direct effect on the subjective well-being of children. Children who formed secure attachments and spent more time with their mothers showed a higher level of subjective well-being. In addition, when children kept a good relationship with their mother quantitatively as well as qualitatively, they acknowledged their own capability and value positively, which led to higher subjective well-being. Conclusion: Findings emphasize that mother-child relationships play significant roles in predicting both the subjective well-being and self-esteem of children. The importance of self-esteem was identified in late childhood based on its relative influence on subjective well-being compared to mother-child relationships.
