This study is about a life history. Through investigating the life of retired teachers in preschool, elementary, and middle schools, authors wanted to explore the meaning of retirement and the process of adaptation to find out their personal and social needs in post-retirement life. Studies have shown that their experiences at childhood have greatly influenced the performance of one's profession, such as contributing to setting limits on behaviors of their students. In the period of interdependence, they have contributed to serving society and the nation beyond as a professional, and in the second half of his teaching career, they have learned that their painful experience was a resource and have realized that changing mind can make the world changed. Since teachers' behavior affects on many subjects unlike other jobs, rewards or satisfaction from the job was bigger than any other jobs. However, after retirement, they felt a sense of emptiness in life without any sense of belonging or accomplishment, while feeling happiness and infinite freedom in other hand. Thy still go forward for life challenging to new study.

This paper's aim is to articulate the educational ideas and methodology of Confucian philosophy in contrast with western classical Philosophy. The ideas and methodology of western classical philosophy is manifested on "the similes of cave" in The Republic of Plato. "The similes of cave" teaches us that 1) philosophy begins with criticism of everyday's consciousness, 2) philosophy is based upon radical philosophical attitude, 3) philosophy request absolute knowledge of the ultimate, 4) philosopher enlightenments the people with absolute knowledge of the ultimate. Confucius said, "at fifteen, I had my mine bent on learning, ⋯⋯ at fifty I knew the decrees of Heaven, ⋯⋯ at seventy, I could follow what my heart desired, without transgressing what was right." This is a typical of philosophical life. Therefore, What the Great Learning as one of confucian Four Books represents, is 1) to illustrate illustrious Virtue, 2) to renovate the people, 3) and to rest in the highest excellence.

This study investigated the effects of a spinal thermal massage device on physical and mental relaxation in office workers. Fifteen participants in their 30s and 40s used the device at home for 40 minutes, five times a week, for one month. Subjective measures, including fatigue, stress, muscle pain, blood circulation, indigestion, and insomnia, were assessed using the Visual Analog Scale (VAS) before and after the intervention. Objective measures included blood pressure (diastolic/systolic) and pulse pressure. The results showed significant reductions in fatigue (-51.5%), muscle pain (-49.6%), blood circulation difficulties (-23.1%), and stress (-20.9%), with trends suggesting reductions in insomnia (-20%) and indigestion (-7.4%). Systolic blood pressure significantly decreased, with tendencies for reductions in diastolic blood pressure and pulse pressure. In conclusion, the spinal thermal massage device appeared to promote physical and mental relaxation by combining thermotherapy and massage, likely activating the parasympathetic nervous system.

In a survey in which farmers were asked about their levels of satisfaction with agricultural machines, Japanese products scored higher than local products by 1.2, 1.3, and 1.4 times for tractors, combine harvesters, and rice transplanter, respectively. Japanese products corresponded to generally high satisfaction levels in terms of operating performance, operability, frequency of breakdowns, and durability, excluding sales price and after-sales services. Effective countermeasures through quality improvement are therefore necessary for Korean products. Furthermore, a survey of dealers showed that the components and consumables for core agricultural machines had high frequencies of breakdowns and repairs. Four major components of tractors represented 85.3% of all breakdowns and repairs, five components of combine harvesters represented 89.6%, and three components of rice transplanters represented 80.5%. Moreover, a comparison of the technological levels between local and imported machines showed that the local machines' levels were at 60-100% for tractors, 70-100% for combine harvesters, and 70-95% for rice transplanters. Small and mid-sized tractors, 4 interrow combine harvesters, and 6 interrow rice transplanters showed similar levels of technology. The results of the analysis suggest that action is urgently needed at a policy level to establish an agricultural machinery component research center for the development, production, and supply of commonly-used components, with the participation of manufacturers of agricultural machines and components, in order to enhance the competitiveness of local manufacturers and to revitalize the agricultural machine market.

The objectives of this study were to explore food-related lifestyle segments of the older consumers, to identify its socio-demographic characteristics, and to investigate the differences in variables regarding health beliefs. A survey was conducted of adults 55 years of age and older living in Seoul, South Korea from March 28 to April 10, 2007. Out of the 500 distributed questionnaires, 361 were retained for final analysis: a response rate of 72.2%. As a result of cluster analysis, five consumer segments were identified; health-managing group, diet-unconcerned group, convenience-oriented group, taste-oriented group, unpracticed group. Significant differences were found among the five segments in terms of socio-demographic characteristics and variables regarding health beliefs (i.e., perceived self-efficacy, perceived barriers, perceived benefits). In the health-managing group and taste-oriented group, mean scores of perceived self-efficacy (p<0.001) and perceived benefits (p<0.001) were significantly higher than other groups. However, in the diet-unconcerned group and convenience-oriented group, the mean scores of perceived barriers (p<0.01) were significantly high. This study shows that foodservice operators targeting the older consumers should consider characteristics of each segment to develop a customized program.

This study was carried out to investigate the quality characteristics of fried fish paste prepared with different amounts of squeezed Aronia melanocarpa juice. Squeezed Aronia melanocarpa juice (AMJ) was incorporated into fish paste at different levels (containing 2, 7, and 12 g of Aronia melanocarpa juice in 2 AMJ, 7 AMJ, and 12 AMJ, respectively) based on the total weight of water. Sugar contents and total acidity increased with increasing AMJ content. With increasing amounts of AMJ in fried fish paste, L value inside and on the surface decreased, a value increased, and b value inside decreased, whereas b value on the surface increased. pH decreased with increasing levels of AMJ. As the result of textural properties, folding test in all samples showed that AA means good flexibility. The strength, hardness, and chewiness of fried fish paste with AMJ increased while cohesiveness was not significantly different. Total polyphenol contents increased with higher levels of AMJ. DPPH radical scavenging activity was significantly higher than those of the control. In the sensory evaluation, fried fish paste containing 7 AMJ received the highest score than both the control and other samples.

This paper examines the interior settings of a chamber and of a temporary place of enshrinement at Yeonghuijeon (永禧殿, Hall of Eternal Happiness), the representative official portrait hall in which portraits of early and late Joseon kings were enshrined. Also, it discusses the features of the Five Peak screens used therein. The physical environment of a chamber at Yeonghuijeon mainly consisted of a four-panel folding screen with a painting of Five Peaks and a large wooden platform, which was adorned with dragon and lion patterns and attached to lotus-leaf column balustrades. The Five Peak screen was installed on a large platform in the shape of ⊓, spreading across the second and third panels on the back and folding out on the first and fourth panels on the right and left sides. When a portrait was enshrined in a temporary place, a simpler and smaller platform with railings was used. A four-panel folding screen of the Five Peak painting was installed in the same way as in a chamber, but was unfolded around a smaller platform behind it. A royal portrait was displayed in each chamber, whereas a case in which a portrait was rolled up was put on the smaller platform in a temporary place. The Five Peak screens for a chamber and a temporary place were all large four-panel folding screens with two wide panels in the middle and two narrow panels on each side, and only strips of silk were mounted on the four edges of the screens without additional wide lower-side mountings. While screens for the chamber used patterned silk for mounting and white paper for backing on screen frames, screens for the temporary place used plain silk and recycled failed test papers for mounting and backing, respectively. By examining records in the literature on the Five Peak screens for Yeonghuijeon, this paper highlights two Five Peak screens, both of which lost their provenance from the hall. The structures of the two screens reflected the way they were to be installed at the hall. Furthermore, this paper assumes that a Five Peak screen, which had been unfolded on the throne in the main hall of Changdeokgung Palace after the 1960s, was produced in 1858 for the purpose of temporarily enshrining King Sunjo's portrait due to the fact that failed test papers of the 1840s were laid taut over the frame.

There were many studies conducted on economical aspects of employment among the elderly in national level, however, very few studies examined social and psychological aspects of senior employment and employment preferences of the elderly persons. The purposes of this study were to examine major determinants of decision making in employment, and to explore some relationships among decision making of employment, socio-economic factors, health and psycho-social factors, and labor and economical factors among non-working elderly persons in the community. In all, two-hundred-twenty elderly persons were interviewed and one-hundred-ninety-four were analyzed in this study. The descriptive statistics, analysis of variance, correlation analysis, and logistic regression were used for the data analysis in this study. The study found that the respondent's sex, ages, education, numbers of children, physical health, ADL, self-efficacy, economical stress, numbers of years in labor, asset of real estate, family allowances, and the benefit levels of pension were major determinants of decision making in employment among non-working elderly persons. Finally, some implications were discussed for developing effective senior employment in national policy, job related services, and welfare programs of the elderly persons for the successful aging.

The quality characteristics of Yanggaeng with 0%, 2%, 4%, 6%, and 8% acaiberry (Euterpe oleracea Mart.) powder added were analyzed for physicochemical, antioxidant effects, and sensory preferences. The moisture contents of the Yanggaeng added with acaiberry powder were significantly(p<0.001) increased as the acaiberry powder levels (0%, 2%, 4%, 6%, and 8%) increased. The pH and $^{\circ}brix$ values of Yanggaeng added with acaiberry powder were significantly reduced as the acaiberry powder levels(0%, 2%, 4%, 6%, and 8%) increased (p<0.001). According to the hunter color of Yanggaeng added with acaiberry powder, the L-value(lightness) and the b-value(yellowness) significantly decreased(p<0.001), whereas the a-value(redness) increased as the acaiberry powder levels increased(p<0.001). For the textural characteristics, the addition of acaiberry powder decreased the hardness(p<0.001), gumminess(p<0.001), cohesiveness(p<0.05), and chewiness(p< 0.01), whereas springiness not significantly changed. The total polyphenol contents and DPPH radical scavenging activities were significantly increased aciberry powder(p<0.01, p<0.001). In sensory evaluation, Yanggaeng addition with 4% acaiberry powder had excellent scores in taste and overall sensory preference. These results suggest that acaiberry powder may be a useful ingredient in Yanggaeng for the improvement of sensory preference and antioxidant potential. Considering both the functional and sensory preference aspects of the acaiberry Yanggaeng, the 4% acaiberry powder dosage level can be considered ideal.

Jerusalem artichoke is often stored poorly after harvesting due to its delicate skin. For this reason, Jerusalem artichoke is mainly distributed in the market as a dried material. In order to improve utilization of dried Jerusalem artichoke, we made Jangachi and analyzed physiochemical characteristics with raw Jerusalem artichoke Jangachi during storage. Raw Jerusalem artichoke was sliced into 7 and 10 mm slices and dried in hot air. After aging, we analyzed rehydration capacity, pH, hardness, salinity, sugar content, and fructan content of both. Dried Jerusalem artichoke sliced into 10 mm slices took over twice as long (420 min) to be rehydrated over 90% than 7 mm sliced (200 min) Jerusalem artichoke. In the case of raw Jerusalem artichoke, hardness showed a tendency to decline. Relatively, hardness of dried Jerusalem artichoke was measured consistently. After 4 weeks, salinity and sugar content were 3.63% and $41.23^{\circ}Brix$ in raw Jerusalem artichoke Jangachi, 3.47% and $37.05^{\circ}Brix$ in 7 mm dried Jerusalem artichoke, and 3.77% and $39.15^{\circ}Brix$ in 10 mm dried sample, respectively. As a result of this study, the possibility of dried Jerusalem artichoke as a pickle was confirmed.
