The study was an exploratory research on the awareness of informatization and attitudes to information technology (IT) and its use among elderly women in a metropolitan area. The questionnaire survey was conducted to collect data on IT use or non-use of elderly women aged 60 or older in senior welfare centers in Seoul, Korea. The data on 343 cases were analysed using SPSS 21.0. As a result, the rate of internet use was relatively high and different according to socio-demographic factors, such as age. The elderly women's attitudes like the levels of awareness and expectation of informatization were positive. Elderly women learned to use IT for psychological, emotional reasons as well as for practical ones, and the satisfaction level of IT use was relatively high. Finally, most IT non-users were indifferent and ignorant about IT use. In addition, the dissatisfaction level of IT non-use was normal, but elderly women had a relatively positive expectation of IT use in the future. This study may contribute to understanding the diverse pictures of IT use and the digital divide in old age, and assist in the development of practical programs and policies for the informatization and welfare for older adults.

Anchoring systems with structural stability and endurance have been one of the most important elements for PSC structures, especially for the structures using non-corrosive FRP tendons. FRP tendons are in increasing use for underground and coastal structures constantly contacted with fresh water or sea water because of their superiority to metallic ones in corrosion-resistance. In this study new non-metallic anchoring system for FRP tendons has been tested and investigated. The newly developed anchoring system utilizes FRP pipes and HEM (Highly Expansive Mortar). The major factors considered in this experiment were expansive pressure of HEM during its hydration and the strength of GFRP(Glass Fiber Reinforced Plastic) Pipe. Anchoring forces of the new anchoring system were investigated from the pull-out testes. The authors analyzed pull-out procedures of the FRP tendons in the various pipe filled with HEM and suggested an improved idea to develop novel non-metallic anchoring system for FRP tendons

The development of routine techniques for the isolation and in vitro maintenance of conducting airway epithelial cells in a differentiated state provides an ideal model to study the factors involved in the regulation of the expression of mucocilicary differentiation. Several key factors and conditions have been identified. These factors and conditions include the use of biphasic culture technique to achieve mucociliary differentiation and the use of such stimulators, the thickness of collagen gel substratum, the calcium level, and vitamin A, and such inhibitors, the growth factors EGF and insulin, and steroid hormones, for mucous cell differentiation. Using the defined culture medium, the life cycle of the mucous cell population in vitro was investigated. It was demonstrated that the majority of the mucous cell population in primary cultures is not involved in DNA replication. However, the mucous cell type is capable of self-renewal in culture and this reproduction is vitamin A dependent. furthermore, differentiation from non-mucous cell type to mucous cell type can be demonstrated by adding back a positive regulator such as vitamin A to the “starved” culture. Cell kinetics data suggest that vitamin A-dependent mucous cell differentiation in culture is a DNA replication-independent process and the process is inhibited by TGF-${\beta}$1.

Purpose. The present study was intended to compare difference in research variables between delinquent adolescents and student adolescents, and to analyze discriminative factors of delinquent behaviors among Korean adolescents. Methods. The research design of this study was a questionnaire survey. Questionnaires were administered to 2,167 adolescents (1,196 students and 971 delinquents), sampled from 8 middle and high school and 6 juvenile corrective institutions, using the proportional stratified random sampling method. Statistical methods employed were Chi-square, t-test, and logistic regression analysis. Results. The discriminative factors of delinquent behaviors were smoking, alcohol use, other drug use, being sexually abused, viewing time of media violence and pornography. Among these discriminative factors, the factor most strongly associated with delinquency was smoking (odds ratio: 32.32). That is, smoking adolescent has a 32-fold higher possibility of becoming a delinquent adolescent than a non-smoking adolescent. Conclusions. Our findings, that smoking was the strongest discriminative factor of delinquent behavior, suggest that educational strategies to prevent adolescent smoking may reduce the rate of juvenile delinquency. Antismoking educational efforts are therefore urgently needed in South Korea.

Canola meal is derived from the crushing of canola seed for oil extraction. Although it has been used in swine diets for a long time, its inclusion levels have been limited due to concerns regarding its nutritive value primarily arising from results of early studies showing negative effects of dietary canola meal inclusion in swine diets. Such effects were attributable to the presence of anti-nutritional factors (ANF; notably glucosinolates) in canola meal. However, due to advances in genetic improvements of canola that have led to production of cultivars with significantly lower ANF content and improved processing procedures, canola meal with a superior nutritive value for non-ruminant animals is now available. Therefore, the aim of this paper is to review the recent studies in the use of canola meal as feedstuff for swine, the factors influencing its use and the strategies to overcome them. First a historical overview of the development of canola is provided.

Objective: The disabled are in a blind spot for obtaining information on drugs, and the pharmacies' counseling on drug use is centered on non-disabled people. Few studies have investigated the current statuses of drug use by type of disability. The purpose of this study is to understand the drug use by type of disability and by life cycle of visually impaired and hearing impaired in Korea. Methods: The study participants consisted of 16 people with visually impairments, 12 people with hearing impairments. One in-depth interview was conducted per participant, and each interview was recorded and documented. Results: Common barriers against safe medication and medical service uses across disability types are 'lack of consideration and service for the disabled, limited access to medical facilities due to disability, limited access to information regarding medication use, psychological anxiety about drug use and side effects, and inconvenience regarding COVID-19 epidemic. The specific factors were 'difficulties in identifying proper medicines and following prescribed dosages' in the case of visually impaired, and 'problems with sign language interpretation system' for the hearing impaired. Conclusion: Disabled people are hindered from using medicines properly due to various factors. Based on the content derived from this study, it is necessary to eliminate the inhibition factors and devise specific measures for the safety of each type of disorder such as developing a method for medication counseling considering disabilities and establishing communication support systems.

This paper describes the results from a prevention program for low-income mothers of children under the age of 13 aiming at the positive change on parental attitudes toward their children, parenting satisfaction and attitudes toward the use of corporal punishment. The program duration was 8 weeks and consisted of two parts: parent education on understanding parent-child relationship, communication skill improvement, techniques of problem solving, non-punitive child rearing techniques; and the recognition and use of existing social support network including networking of the neighborhood resources. The pre-post test control group design was employed. The results are: the program is effective on bringing some positive changes on an three variables: parental attitudes toward their children, parenting satisfaction and attitudes toward the use of corporal punishment. Increased social support was found to have significant positive effect on the above variables except the attitudes toward corporal punishment. To decrease the risk factors as well as to increase the protective factors of child abuse, well designed parent education and social support program is recommended on every community level.

Purpose: The purpose of this study was to identify factors affecting the social competence of school-aged children according alcohol consumption by their parents. Methods: The participants were 558 5th grade elementary school students. Data were collected using structured questionnaires from September 17 to October 2 2013, and analyzed using descriptive statistics, ${\chi}^2$-test, t-test, ANOVA, Pearson correlation coefficients, and Stepwise multiple regression analysis with the SPSS PC+ 21.0 program. Results: Participants were classified into three groups according to alcohol use; Non-use parent group (52.7%), social use parent group (31.0%), and problem use parent group (16.3%). Participants whose parents were problem users had significantly lower scores on emotional awareness and expression (F=14.45, p<.001), social support (F=5.82, p=.003), and social competence (F=16.33, p<.001) compared to students in the other two groups. In school-aged children with parents who were alcohol abusers, the variables that predicted social competence was friend support (66.0%). Conclusion: These results emphasize the importance of focusing on the crucial role of peer support in the development of social competence in school-aged children of parents who abuse alcohol. Further, for these children, interventions aimed at improving social support and children's emotional awareness and expression may be most beneficial.

Objectives: Lately, non alcoholic fatty liver patients are increasing rapidly and the average age of patients are getting younger. Non alcoholic fatty liver often represents asymptomatic and korean pattern diagnosis is difficult to implement without symptoms. This study aimed to analyze interrelationship between non alcoholic fatty liver disease and Injinho-tang. Methods The AHP is a systematic procedure for analyzing the elements of any problem hierarchically. Based on survey of expertise, as series of pairwise comparison judgements is performed to evaluate the various elements in the hierarchy. We are expected to use the AHP analysis that would apply to oriental doctor's diagnostic process analysis. Results and conclusion Non-alcoholic fatty liver disease induced complex causes of the metabolic syndrome. Injinho-tang has been widely used disease that causes jaundice and liver biliary disease. According to AHP analysis, LFT is the most important facor in choosing Injinho-tang on non alcoholic fatty liver disease. BMI and body composition by bioelectrical impedance analysis are the next important factors. Personal hot temper also gives a big impact on choicing Injinho-tang on non alcoholic fatty liver disease.

This study was designed to compare general characteristics and dietary habits between volunteers for a nutrition survey and non-volunteers using a questionnaire. Volunteers were recruited by advertising on the homepage of a university to assess nutritional status by examining dietary intake for three days and blood analysis. Non-volunteers were selected from some classes not related to nutrition. There were no significant differences in sex, monthly allowances, eating-out cost, drinking and exercise between the two groups, while the proportion of self-boarding was higher in the volunteer group than in the non-volunteer group, and smoking rate of volunteers was approximately 2.4 times lower than that of non-volunteers. Volunteers were less concerned about their diet than non-volunteers. No significant differences in concern about health, considering factors in their diet, self-evaluation of their diet, learning experience about nutrition, and vitamin/mineral supplement use were observed. The frequency and the place of eating-out for dinner were significantly different between the two groups. More proportions of volunteers tended to eat regularly and eat breakfast. Volunteers consumed seaweeds more frequently, and milk, fruits and fast foods less frequently than non-volunteers. Our results indicate that some characteristics and dietary habits of volunteers are different from those of non-volunteers. However, we could not show that volunteers were more interested in their diet and had desirable dietary habits than non-volunteers. Further research on the characteristics of volunteers who participate in nutrition survey may be helpful to interpret and generalize the survey results.
