In this study, batcher plant composition test and mock-up test were carried out to conduct comparison and analysis on flow behavior and strength properties of concrete at early age. As a result, it was found that slump and amount of air in batcher plant composition test reached the target range. As for compressive strength, composition using HESPC showed the most excellent strength development. In mock-up test which was carried out to find out the strength properties, two methods with specimen and core test body both revealed HESPC as the most excellent composition. However, strength estimation with ultrasonic survey presented less reliable data. As a result of the previously conducted indoor composition test and the mock-up test in this study, target performance of concrete at early age was 4day/cycle. It was found that the optimum conditions that meet the required strength, 5MPa/18hr and 14MPa/36hr in mullion and transom are; curing temperature above 15℃, W/B 45%, unit-water 165kg/㎥ and CHC cement.

The aim of this paper was to look at the distribution intensity for the women's formal wear industry. Most of the previous works on the distribution design have stressed product characteristics and consumer's shopping behaviours. The firm especially in women's aopparel industry recently has had difficulty in how to decide and to select the distribution numbers in the domestic market. Thus five hypothesis were set based on the data in '98Korea Fashion Guide describing the brand of women's wear in detail. It has been published by Korea Fashion Association in 1997. The variables of this study were the price the total sale the launching period the target customer's age and brand origins related with domestic or foreign. 579 brands had been analyzed with percentage anova duncan's test pearson's correlation and t-test. the results were as follows: In general the higher the price of the product is the less intensive the distribution of the women's apparel industry is. The higher the total sale is and the younger the target customer's age is the more intensive the distribution of the women's apparel industry is Besides there is difference between the domestic brand and the foreign brand in the distribution intensity. There is no relationship between the launching period of the brand and the distribution intensity. In addition four brand types were classified into the national brand the designer brand the licensed brand and the imported brand. Satatistically variables have shown different relations in terms of each brand type.

Aging is the most important single risk factor for many chronic diseases such as cancer, metabolic syndrome, and neurodegenerative disorders. Targeting aging itself might, therefore, be a better strategy than targeting each chronic disease individually for enhancing human health. Although much should be achieved for completely understanding the biological basis of aging, cellular senescence is now believed to mainly contribute to organismal aging via two independent, yet not mutually exclusive mechanisms: on the one hand, senescence of stem cells leads to exhaustion of stem cells and thus decreases tissue regeneration. On the other hand, senescent cells secrete many proinflammatory cytokines, chemokines, growth factors, and proteases, collectively termed as the senescence-associated secretory phenotype (SASP), which causes chronic inflammation and tissue dysfunction. Much effort has been recently made to therapeutically target detrimental effects of cellular senescence including selectively eliminating senescent cells (senolytics) and modulating a proinflammatory senescent secretome (senostatics). Here, we discuss current progress and limitations in understanding molecular mechanisms of senolytics and senostatics and therapeutic strategies for applying them. Furthermore, we propose how these novel interventions for aging treatment could be improved, based on lessons learned from cancer treatment.

This study aimed to analyze the characteristics of domestic textile designs for miss and madam apparel and to find out the trend sensibility felt by young female judge according to the product year and apparel target age. Textile designs of 170 pictures of 1999 and 1994-1995 were collected at 4 shopping malls and from consumers, and results are as follows; As the sources of textile design were 'nature', 'imagination', and 'combination' used in the order of frequence, but the sources appeared more diverse in 1999 than in 1994-1995. The interpretation techniques expressed most often were 'stylized', 'geometry', and the mast frequent arrangements were 'all over', and the second was '4-way' in 19941995, '2-way' in 1999, that is, the arrangement were different according to product year. The trend sensibility were varying to the target age and product year.1999 apparel products were felt more 'sophisticated', 'contemporary', and 'sporty' if they were the textile designs for miss, while 1994-1995 products were more 'sophisticated', 'contemparary', and 'sporty' if for madam.

This study was aim to compare the phonological error patterns and PCC(Percentage of Correct Consonants) derived from the single word and spontaneous speech contexts of the speech sound disorders with unknown origin(SSD). The present study suggest that the development phonological error patterns and non-developmental error patterns of the target children, in according to speech context. The subjects were 15 children with SSD up to the age of 5 from 3 years of age. This research use 37 words of APAC(Assessment of Phonology & Articulation for Children) in the single word context and 100 eojeol in the spontaneous speech context. There was no difference of PCC between the single word and the spontaneous speech contexts. Significantly different developmental phonological error patterns between the single word and the spontaneous speech contexts were syllable deletion, word-medial onset deletion, liquid deletion, gliding, affrication, fricative other error, tensing, regressive assimilation. Significantly different non-developmental phonological error patterns were backing, addtion of phoneme, aspirating. The study showed that there was no difference of PCC between elicited single word and spontaneous conversational context. And there were some different phonological error patterns derived from the two contexts of the speech sound disorders. The more important interventions target is the error patterns of the spontaneous speech contexts for the immediate generalization and rising overall intelligibility.

Purpose: The purpose of this study was to find out the personal characteristics of physical therapists, dementia awareness and dementia attitude, and to find out what relationship is there between personal characteristics and dementia awareness and dementia attitude. Methods: Participants in this study surveyed physical therapists who are members of the Association of Korean Physical Therapists on their awareness of dementia, and conducted online surveys from January 28 to February 27, 2021. The survey questions used in the survey consisted of 29 questions in total, including 9 general characteristics of the participant, 10 questions on perception of dementia, and 10 attitudes toward dementia. All 104 participants were surveyed, and 100 surveys were analyzed, excluding 4 surveys with insufficient responses. Results: In this study, the correct answer rate for all items in the dementia awareness sub-item was 65%, and the dementia attitude-related sub-items were generally positive. However, there was no significant correlation between personal characteristics such as gender, age, educational background, treatment target, treatment experience and dementia awareness, and no correlation with dementia attitude was significant. Conclusion: Regardless of personal characteristics such as gender, age, treatment target, and treatment experience, a positive attitude and correct recognition of dementia can improve the quality of treatment with dementia patients and increase the reliability of patients and caregivers.

The objective of this study was to use cluster analysis to determine differences in eating-out behavior among grouped clusters of female consumers after each cluster was divided based on lifestyle patterns. The data were collected by interview survey from a biased sample of 1,300 females, ranging from ages 20 to 59, and living in residential districts of Seoul. Reliability analysis, factor analysis, cluster analysis, cross-tabulation analysis, and analysis of variance (ANOVA) were applied to the data. Four lifestyle factors were extracted by lower-division and classified as follows: health condition, consuming, food, and housing lifestyles. Based on these four factors, the female consumers were grouped as three clusters: the consuming-individuality type, rational-pursuit type, and conservative-stability type. The eating-out behavior of each cluster was significantly different in terms of frequency of eating-out, eating-out expenditures, restaurant selection criteria, food preferences, and the purpose for eating-out. Since this study surveyed females from ages 20 to 59, age and demographics were the differential factors in determining the various lifestyle types. Thus, to target the consumers who form a target market, the food industry should consider market segmentation that combines demographic factors such as age, income, and marital status.

Mitochondria have long been recognized as ATP engines for the cell and recently as a dynamic and mobile organelles that control cell death and life. This exquisite organelle is the site of reactive oxygen species production and is highly vulnerable to exogenous stresses, resulting in catastrophic damage to the cell. Mitochondrial dysfunction is linked to a wide range of age-associated degenerative diseases, such as metabolic syndrome, cardiovascular disease, and neurodegenerative diseases. Understanding the molecular mechanisms of mitochondria-dependent pathogenesis may provide important strategies to treat these diseases. Indeed, mitochondria are emerging therapeutic targets for the mitochondria-related diseases. In this paper, we review the recent concepts of mitochondrial biology and how mitochondria are involved in age-associated degenerative diseases. Furthermore, we summarize the therapeutics which target to improve mitochondrial functions.

This study explores the interior image preferred by females living in urban areas. It also examines the relationship between interior image and socio-demographic characteristics such as age, marital status, employment status, total household income. The target population of this study was 301 adult females living in Kwangju City. The data were analyzed with frequency, percentage, General Linear Model, and Duncan's multiple range test using the SAS package. The major findings of this study were as follows. 1) The majority of the females generally preferred modernity of interior image to traditionalism. Also they preferred feminity of interior image to masculinity and complexity to simplicity. 2) Females in the age of 40s were more likely to prefer simple and oriental-traditionalism image to those under the age of 30s. 3) Those with the higher total household income were more 1ike1y prefer western-traditionalism image to those with the lower. But those with the lower household income were more tended to prefer modernity image to those with the higher.

In this paper, the author devised new decision recommendation ordering method of items attributed by age to improve accuracy of recommender system. In conventional recommendation system, recommendation order is decided by high order of preference prediction. However, in this paper, recommendation accuracy is improved by decision recommendation order method that reflect age attribute of target customer and neighborhood in preference prediction. By applying decision recommendation order method to recommender system, recommendation accuracy is improved more than conventional ordering method of recommendation.
