The purpose of this study was parents' perception on young children's safety life, safety accident, and safety education and provided basic data of administrating parent education for young children's safety. Subjects of this study were 620 parents (310 fathers and 310 mothers) of young children attending at four public kindergartens and two day care centers located in C city and D county. The results of the study were as follows: First, regarding parents' perception on young children's safety life, parents thought that their perception and attitude would mostly affect young children' safety life. Second, with regard to parents' perception on safety accident, half of parents experienced such safety accident as accident during play, traffic accident, accident in dangerous places, accident from dangerous matters, accident in sport activities, fire, and electric shock. Third, most parents looked upon safety education as very important one, and fathers were more satisfied with the safety education administered by kindergartens. Fourth, with regard to parents' perception on parent education for young children's safety, most parents thought that parent education for safety would be necessary. They ranked traffic and play accidents as the most important contents of safety education.

The effect of structured water by dissolution of xenon was examined from the view point of the suppression of both browning and respiratory metabolism of broccoli. The structured water is formed duet to hydrophobic interaction when xenon gas dissolves into water. NMR measurements were carried out to determine proton spin-spin relaxation time, T2, for water. There was a difference in proton T2 between distilled water and structured water. This can be interpreted as the change of water structure. Fro the broccoli cut in half stored for 16 days at 279K, the section color did not change appreciably for the sample whose water was structured by dissolution of xenon whose initial partial pressure was 0.39MPa. In contrast to this, the browning of section surface was observed for the sample stored under the condition of nitrogen gas at the same partial pressure as xenon and for the sample stored under atmospheric condition . These results led to the conclusion that the suppression of b owning by oxidation was due to structured water but not to applied pressure. Adding to this, the water structured by xenon has resulted in suppression of respiratory metabolism of broccoli.

To investigate the diversity of gastrointestinal microflora and lignocellulose-degrading enzymes in wild Asian elephants, three of these animals living in the same group were selected for study from the Wild Elephant Valley in the Xishuangbanna Nature Reserve of Yunnan Province, China. Fresh fecal samples from the three wild Asian elephants were analyzed by metagenomic sequencing to study the diversity of their gastrointestinal microbes and cellulolytic enzymes. There were a high abundance of Firmicutes and a higher abundance of hemicellulose-degrading hydrolases than cellulose-degrading hydrolases in the wild Asian elephants. Furthermore, there were a high abundance and a rich diversity of carbohydrate active enzymes (CAZymes) obtained from the gene set annotation of the three samples, with the majority of them showing low identity with the CAZy database entry. About half of the CAZymes had no species source at the phylum or genus level. These indicated that the wild Asian elephants might possess greater ability to digest hemicellulose than cellulose to provide energy, and moreover, the gastrointestinal tracts of these pachyderms might be a potential source of novel efficient lignocellulose-degrading enzymes. Therefore, the exploitation and utilization of these enzyme resources could help us to alleviate the current energy crisis and ensure food security.

Pancreatic cancer is among the most difficult-to-treat tumors. More than half of patients with this cancer have very few symptoms at the early stages, allowing the development of distant metastases and resistance to cancer treatment. In this study, we found that Juniperus chinensis extract (JCX) decreased the cell viability and migration activity of PANC-1 and SNU-213 pancreatic cancer cells in a dose-dependent manner. JCX increased caspase-3 activation and generation of reactive oxygen species (ROS). N-acetylcysteine treatment blocked JCX-induced ROS generation and the negative effects on pancreatic cancer cell viability. In addition, JCX down-regulated the levels of phospho-focal adhesion kinase (p-FAK) and phospho-extracellular signal-regulated kinase (p-ERK). Together, these results indicate that JCX induces apoptosis in human pancreatic cancer cell lines through ROS production, downregulating FAK/ERK signaling and activating caspase-3. We propose that JCX-derived compounds represent candidates for the development of alternative medicines for the treatment of pancreatic cancer.

The change in the police concerning food and dietary life were analyzed in order to provide bases of establishing policy of food and dietary life properly. The last half one century was divided into six periods as follows ; The period since liberlation from Japanese rule(1945-1949) the 1950's (1950-1959) 1960's (1960-1969) 1970's (1970-1979) 1980's (1980-1989) 1990's (1990-1992). Dietary life by 1960's were a life of distress and policies coducted by government took on an relief supply of food at this period. Movement about 'intake of mixed rice with barley and foods from flour' to supress rice consumption were encouraged by government. And Korean recommended dietary allowance was made and the national nutritional survey was practived in the first place by the Ministry of Health and Social Affairs. Dietary life of the country begin to improve sharply along with rice self-sufficiency since 1975 With the growth of food and eating out industry intake of instant food processed food and fast food has increased at the 1980's To ministry of Health and Social Affairs drove campaign of 'Joo-Moon Sik Dahn Je' for dietary life improvement at 1981 The Ministry of Education made and announced a 'School Feeding Law' at 1981 The government that is the Office of Permier and the Ministry of Health and Social Affairs developed compaign for improvement of dietary life and drove 'Jo Eun Sik Dahan Je' with Association of restaurant jointly. Policy on food and dietary life conducted by government up to data were planned mainly dependent on food production supply and demand of food. Infectious diseases continue to decrease with increasing of degenerative diseases which will be required proper management of dietary life. In the future more aggressive intergrated food policy are needed to maintain the public health. Aoso dietary improvement movement should be drived actively.

Purpose: The purpose of the present study was to analyze and evaluate prior studies published in Korea on the cardiovascular disease-related quality of life, in order to make recommendations for further research. Methods: A total of 15 studies were selected from four databases(Digital library of Research Information Center for Health, Korea Medical Database, MedRic, and National Assembly Library). The selected studies were analyzed according to criteria, such as diagnosis/operation, used instrument, generic/specific instrument, dimension of quality of life, translation/ back-translation, sample size, reliability, validity, responsiveness, number of items, type of scale, time required, and independent variables. Results: Of the 15 cardiovascular disease-related quality of life studies, approximately half of them were conducted with hypertension or ischemic heart disease patients. All studies asserted that the concept of quality of life had multidimensional attributes. With respect to the questionnaire used for measuring the quality of life, only one study used a cardiovascular disease specific-instrument and most studies did not consider whether or not the validity of their instrument had been established. In addition, when using questionnaires developed in other languages, only one study employed a translation/back-translation technique. The types of variables tested for their influence on quality of life were quite limited. Conclusion: It is recommended to develop a reliability and validity established cardiovascular disease specific-quality of life for Korean patients and to identify associated new variables.

The second half of the 20th century was marked with a significant raise in amount of railway bridges in Austria made of reinforced concrete. Today, many of these bridges are slowly approaching the end of their envisaged service life. Current methodology of assessment and evaluation of structural condition is based on visual inspections, which, due to its subjectivity, can lead to delayed interventions, irreparable damages and additional costs. Thus, to support engineers in the process of structural evaluation and prediction of the remaining service life, the Austrian Federal Railways (${\ddot{O}}$ BB) commissioned the formation of a concept for an anticipatory life cycle management of engineering structures. The part concerning concrete bridges consisted of forming a bridge management system (BMS) in a form of a web-based analysis tool, known as the LeCIE_tool. Contrary to most BMSs, where prediction of a condition is based on Markovian models, in the LeCIE_tool, the time-dependent deterioration mechanisms of chloride- and carbonation-induced corrosion are used as the most common deterioration processes in transportation infrastructure. Hence, the main aim of this article is to describe the background of the introduced tool, with a discussion on exposure classes and crucial parameters of chloride ingress and carbonation models. Moreover, the article presents a verification of the generated analysis tool through service life prediction on a dozen of bridges of the Austrian railway network, as well as a case study with a more detailed description and implementation of the concept applied.

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.
