The structures of reinforced concrete have been extensively increased with rapid development of industrial society. Futhermore, these reinforced concretes are easy to expose to severe corrosive environments such as seawater, contaminated water, acid rain and seashore etc.. Thus, corrosion problem of steel bar embedded in concrete is very important in terms of safety and economical point of view. In this study, specimens having six different coating thickness (W/C:0.5) were prepared and immersed in flowing seawater for five years to evaluate the effect of coating thickness and immersion time on corrosion property. The polarization characteristics of these embedded steel bars were investigated using electrochemical methods such as corrosion potential, anodic polarization curve, and impedance. At the 20-day immersion, the corrosion potentials exhibited increasingly nobler values with coating thickness. However, after 5-yr. immersion their values were shifted in the negative direction, and the relationship between corrosion potential and coating thickness was not shown. Although 5-yr. immersion lowered corrosion potential, 5-yr. immersion did not increase corrosion rate. In addition, after 5-yr. immersion, the thinner cover thickness, corrosion current density was decreased with thinning coating thickness. It is due to the fact that ease incorporation of water, dissolved oxygen and chloride ion into a steel surface caused corrosion and hence, leaded to the formation of corrosion product. The corrosion product plays the role as a corrosion barrier and increases polarization resistance. The corrosion probability evaluated depending on corrosion potential may not be a good method for predicting corrosion probability. Hence, the parameters including cover thickness and passed aged years as well as corrosion potential is suggested to be considered for better assessment of corrosion probability of reinforced steel exposed to partially or fully in marine environment for long years.

This study was performed to evaluate the effect of the fermented beef rib sauce (FBS) on the change of quality characteristics and sensory properties of aged and seasoned beef rib with FBS. The FBS was manufactured by fermentation with Zygosaccharomyces rouxii Y-80 yeast in raw sauce ingredients. The decreasing changes of pH of seasoned beef rib with FBS showed a similar pattern as compared with seasoned beef rib by non-fermented beef rib sauce (NFBS) during aging periods. The cooking loss of the seasoned beef rib with FBS and NFBS exhibited minor changes, respectively. Water holding capacity of the seasoned beef rib with FBS was nearly unchanged, but that of the seasoned beef rib with NFBS increased from 83% to 91% after 5 day aging. Shear forces of the seasoned beef rib with FBS were lower than those of the seasoned beef rib with NFBS. The yellowness and lightness of the seasoned beef rib with FBS decreased as compared with the seasoned beef rib with NFBS, but redness of the seasoned beef rib with FBS was more stable than that of the seasoned beef rib with NFBS. The sensory evaluation indicated that color, aroma and overall acceptability of the seasoned beef rib with FBS were scored relatively higher than those of the seasoned beef rib with NFBS.

WIn Korea, the rapid rise of elderly population and dementia prevalence resulting from the unprecedently rapid aging in the world is being emerged as a serious social issue. Caring the elderly with dementia is a different way from a general life and is a world which new cultural existential relationships are interlaced from the relationship viewpoint. From this aspect, the psychological matter of family caring a demented elderly needs to be studied for existential understanding in depth and fundamentally. This study focused on in-depth understanding and description of the stress phenomena experienced by family caregivers with a demented elderly based on Giorgi's method among phenomenological research methods and using existential group counseling techniques. Total 8 sessions of existential group counseling were conducted. This study drew out the outcomes(emotional stress, psychosocial stress, time-dependent stress) of participants' self-awareness experiences by applying 4 steps of Giorgi's phenomenological research methodology based on the Existential Philosophy to participant's intensive statements about stress of family caring a demented elderly drawn out of the existential group counselling sessions. It is hoped that understanding the pain of the supporters who cannot express their own pains through the research results and their self-help group counseling activities will become active, contributing to the health of our society which is about to enter post-aged society.

This study was carried out to investigate the effects of age of laying hens and grade of shell abnormality on internal egg quality. At each week, 1,000 eggs were randomly selected from 21,000 eggs laid by Hy-Line hens (100,000 birds) aged from 56 to 62 wk. The samples were divided into normal and externally abnormal eggs by an official egg grader. Then, egg quality including egg weight, egg white height, Haugh unit and yolk color was evaluated from each normal and abnormal eggs. The production rate of externally normal and abnormal eggs was 81.22 and 18.78%, respectively. No difference found in the production rate by the increase of hen's age, but Haugh unit of eggs from hens of 60-wk-old was higher (p<0.05) than that of 56-wk-old. When the same age groups were compared, egg white height and Haugh unit were lower in eggs which were externally abnormal. When the grade of abnormality increased, egg white height and Haugh unit were decreased further (p<0.05). Among the externally abnormal eggs, malformation showed the lowest Haugh unit. In conclusion, the shell abnormality of eggs laid by hens aged 56 to 62 wk was closely related with internal egg quality. Therefore, the grading external egg quality in the present egg grading system is directly related with the internal egg freshness.

The structures of reinforced concrete has been extensively increased with rapid development of industrial society. Futhermore, these reinforced concretes are easy to expose to severe corrosive environments such as sea water, contaminated water, acid rain and seashore etc.. Thus, corrosion problem of inner steel bar embedded in concrete is very important in terms of safety and economical point of view. In this study, multiple mortar test specimen(W/C:0.4) with six types having different cover thickness each other was prepared and was immerged in seawater solution for five years to evaluate the effect of cover thickness and immersion years to corrosion property of embedded steel bar. And the polarization characteristics of these embedded steel bars was investigated using electrochemical methods such as measuring corrosion potential, cathodic polarization curve, and cyclic voltammogram. At the beginning of immersion, the corrosion potentials exhibited increasingly nobler values with increasing cover thickness. However, after immersed for 5 years, the thicker cover of thickness, the corrosion potentials shifted in the negative direction, and the relationship between corrosion potential and cover thickness was not in good agreement with each other. Therefore, it is considered that the thinner cover of thickness, corrosive products deposited on the surface of the embedded steel bar plays the role as a resistance polarization which is resulted in decreasing the corrosion rate as well as shifting the corrosion potential in the positive direction. As a result, it seemed that the evaluation which corrosion possibility of the reinforced steel would be estimated by only measuring the corrosion potential may not be a completely desirable method. Therefore, it is suggested that we should take into account various parameters, including cover thickness, passed aged years as well as corrosion potential for more accurate assessment of corrosion possibility of reinforced steel which is exposed to partially or fully in marine environment for long years.

From Post-Modern Edo-language of Japan, it is possible to find expression formats related to current Tokyo language. However, in some cases, Tokyo language and Edo-language has the same format but different usage. One example is the ending portion of a sentence. This research investigates conclusive expressions of Edo-language in literary works excluding the usage of "ダ". Various formats of conclusive expressions appear in a conversation, and the usage is closely related to the speaker's sex, age, and social status. Also from the study, it was possible to see that the social relationship between a speaker and a listener and a conversation circumstance has an effect on the usage of conclusive expressions. In addition, usage does not conform to the current standard Japanese. 1. Currently "である(dearu)" format is seldom used in speaking, it is used with "だ" only in writing. The study found no case of "である(dearu)" in conclusive expressions but some use of "であろうて(dearoute) であらうな(dearouna)" "であったのう(deattanou) であったよ(deattayo)" only in old aged male. 2. "であります(dearimasu)" format is a typical Edo-language used by society-women (Japanese hostess who has a good education and an elegant speaking skills). This format was used once in "浮世風呂"(ukiyoburo) and 14 times in "梅?"(umegoyomi), but speakers were always a female. The reason for 14 occurrences in "梅?" is closely related to the fact that the main characters are society-women and genre is "人情本(ninjoubourn)" which is popular type of cultural literature (based on humanity and romance) in late Edo period. 3. "でござる" format is originally used as a respect-language but later changed to a polite language. The format is always used by male. It is a male language used by old aged people with a genteel manner such as a medical doctor, a retired man, or a funny-song writer. 4. "ございます(gozaimasu) ごぜへます(gozeemasu)" The study found the speaker's social status has a connection with the use of "ごぜへます(gozeemasu)" format. Which is "ございます(gozaimasu)" format but instead of [ai], long vowel [eː] is used. "ごぜへます(gozeemasu)" is more used by a female than a male and only used by young and mid-to-low class people. The format has a tough nuance and less elegant feel, therefore high class and/or educated ladies have a clear tendency to avoiding it

For the purpose of searching examination in the connection with clinical medicine and the basic theory of Korean Medicine, we comparatively studied on the physiological system of Hyun-Gok (1912~1987) and the Hyunsang system of Ji-San (1927~2000). The results are as follows. The metabolism of Yin and Yang is connected 'Gallbladder (膽)'-'Bladder (膀胱)' and Man (男), Woman (女), Old aged (老), Young child (小) style. Man and Woman are divided in the body form chacteristic not by the sex. 'Gallbladder (膽)'-'Bladder (膀胱)' style are divided in the body form chacteristic by the terms of Yin (陰) and Yang (陽). 'Gallbladder (膽)' style represents excessive Yang and deficient Yin, 'Bladder (膀胱)' style represents excessive Yin and deficient Yang. The four composition factor of the body is connected Material basis (精) type, Vital energy (氣) type, Mental faculties (神) type and Blood (血) type. In the diagnosis of body form on the Hyungsang Medicine, there are several types of body shape and categories of people. The Material basis (精) type, Vital energy (氣) type, Mental faculties (神) type and Blood (血) type are classified by the four composition factor of the body. The structural-mechanics organization of five Internal Organs (臟) is connected five Internal Organs (臟) types and the running-animal (走), bird (鳥), fish (魚), turtle (甲) types in the Hyunsang system. The five Internal Organs (臟) types are percived on the ears, eyes, nose, mouth and facial complexion. And the running-animal, bird, fish, turtle types are accorded to the individual personalities and the most-developed part in the body trunk by the Organ picture (藏象) theory. The six atmospheric influences (六氣) is connected the six Kyung types (六經形). The six Kyung types are regulated by the shape of eyes and nose representing for the relation of Vital energy (氣) and Blood (血). By the comparative study on the physiological system of Hyun-Gok and the Hyunsang system of Ji-San, we can search the connection with clinical medicine and the basic theory of Korean Medicine.

Disabled elderly faced with disability and the aged problems at the same time. So, this research creates two research questions and examines. First research question is how nine dimensions of daily life satisfaction according to gender difference. Second research question is how the factor of daily life satisfaction by gender difference. The data is sixty-five disabled elderly, 386 among Panel Survey of Employment for the Disabled(PSED, 2008). The methods of analysis for identifying research questions is t-test and multiple linear regression. The result of analysis on first research question, the gender difference six dimensions among nine dimensions of daily life satisfaction come out statistically significant. And The result of analysis on second research question, come out statistically significant, too. Socioeconomic status: the lower class, physical condition: bad health, chronic disease is or not, family and other people's social supports, disability: serious turn out to be factors in common. It has been suggested social policies from the results of studies that the provision of health support policy and program, enlarge assistance on daily life, support system on serious disabled elderly. On the other hand, analysis showed that distinctive factors between disabled elderly man and woman was age and education level. In other words, disabled elderly woman come out into the open that the more grow old, the less daily life satisfaction low, while disabled elderly man appeared higher daily life satisfaction in case of junior and senior high school graduate than uneducated.
