Pathogenic bacteria that colonize the human intestinal tract have evolved strategies to overcome acidic conditions when they pass through the gastrointestinal tract. Amino acid-mediated acid resistance systems are effective survival strategies in a stomach that is full of amino acid substrate. The amino acid antiporter, amino acid decarboxylase, and ClC chloride antiporter are all engaged in these systems, and each one plays a role in protecting against or adapting to the acidic environment. The ClC chloride antiporter, a member of the ClC channel family, eliminates negatively charged intracellular chloride ions to avoid inner membrane hyperpolarization as an electrical shunt of the acid resistance system. In this review, we will discuss the structure and function of the prokaryotic ClC chloride antiporter of amino acid-mediated acid resistance system.

Purpose: The purpose of this study is to investigate changes in health promoting life style and weight control behavior among nursing students during their two years of college, and to identify the relationship between the changes and their perceived health status. Methods: The subjects were 264 female students in a three-year nursing college in Seoul, Korea. Data was analyzed by paired t-test, Wilcoxon signed-rank test, and multiple logistic regression using SPSS ver.21. Results: Of the six sub-categories regarding health promoting life style, five except spiritual growth showed improvement after two years, but their perceived health status did not change significantly. The number of students who engaged in weight control behavior increased, but there was no change in the number of students who engaged both in weight control and in diet. The group which recorded high scores in perceived mental health status showed 1.2 times greater positive changes in health promoting lifestyle (OR=1.202, p=.023). Conclusion: The results showed although health promoting behavior changed positively throughout the nursing curriculum, physical activities were still low and few students used constructive methods to control their weight. Therefore, it is recommended that nursing colleges build specific programs into their curriculum to correct students' undesirable health promoting behavior.

The purpose of this study was to examine the determinants of economic contributions of home-based family businesses. The results suggested that positive effect on direct contributions of home-based family businesses was associated with a male manager, more family members, more employees, non-family employees in the business, engaged in food and restaurant business, located in Seoul area, and higher perceived success of the business. Positive effect on indirect contributions of home-based family businesses was associated with a female manager, a child under age 6, only family members as employees, and greater initial investment in the business. Working hours were negatively related to the indirect contributions. Greater total economic contributions of the home-based family businesses was associated with a male manager, more family members, more employees, non-family employees in the business, engaged in restaurant business, located in Seoul, and higher perceived success on the business.

The purpose of this study is to investigate low- and middle-income preschoolers' use of contextualized and decontextualized talk. The contextualized and decontextualized talk of 70 five-year-old children were analyzed by children's gender and their socioeconomic status. The participants, as dyads, participated in a peer play session for 10 minutes. The play sessions were videotaped and the videotaped data were transcribed. Each transcript was analyzed according to the modified version of Curenton et al. (2008)'s coding schemes. The results showed that children from middle-income families engaged more in both contextualized and decontextualized talk than children from low-income families. Also, girls from middle-income families engaged in more contextualized-decontextualized talk(psychological states) than girls from low-income families.

This study investigated how kindergarten teachers apply children's traditional play to educational curriculum and how kindergarten children engaged in traditional play. The subjects of this study were 120 kindergarten teachers and their 2930 5-year-old kindergarten children. Data were gathered through questionnaires. The results showed that most teachers included children's traditional play in educational curriculum as indoor and outdoor play activities, but they had difficulties in this process by lack of play materials and their knowledge of children's traditional play. The results also showed that kindergarten children played "Yut" most frequently and, in most cases, they engaged in traditional play in ways which were adjusted to their developmental level and life style.

This study examined the effects of group exercise program on health conditions and quality of life in cerebral palsy. Adults with cerebral palsy in their 20's who participated in the evaluation of measurement tools prior to and following the experiment. The control group was engaged in manual exercise for the range of joint movement and extension exercise for arms, legs and trunk, and experimental group performed group exercise program including boccia exercise. The health condition and quality of life of the experimental group were significantly increased after intervention (.05<). There was a slight increase in the control group, however it was not statistically significant. As a result of comparing the health condition and quality of life of the two groups, the value of the experimental group was significantly higher than that of the control group. The results of this study suggest that exercise programs for patients with cerebral palsy in the twenties are considered as beneficial interventions to improve health conditions and quality of life.

Boredom is considered anxiety and is an experience accompanied by a lack of meaning because the need for meaning is not met. It is the pain that people feel without using their mind, and the suffering that people fall into the absence of desire. On the other hand, religious activities give people meaning in life, which reduces the tendency to feel bored. This study investigates whether there is a difference in boredom depending on whether individuals participate in religious activities, and to verify whether the meaning in life mediates the relationships between religious activities and boredom. We predicted that if individuals engaged in religious activities, the meaning in life would increase, and they would be less bored than those who did not. A total of 82 college students participated in this study. Results showed that there were significant differences in the meaning in life and boredom between the two groups according to whether they participated in religious activities or not. The group actively participating in religious activities had significantly higher meaning in life and lower boredom than the non-religious group. Second, the meaning in life significantly mediated the relationship between religious activities and boredom. We conclude that active participation in religious activities can increase the meaning in life and ultimately reduce boredom. Based on the results of this study, the implications and suggestions for follow-up studies are discussed.

In order to reduce the risk of death from hypothermia for the fishing vessel's crew at sea, this paper suggests that the criteria of equipment of fishing vessels should be revised for fishing vessels engaged in coastal and inshore fisheries to be equipped with the immersion suit. The criteria of equipment of fishing vessels for immersion suits was amended to reflect the sinking of No.501 Oryongho but it was only reflected in ocean fisheries at Bering sea and Antarctic ocean that immersion suits must be provided with the same number of the total number of crew on board. Therefore, this paper analyses the relationship between maritime accident of fishing vessels and weather condition based on sea water temperature to find out the risk of hypothermia and also compares the international conventions(SFV Protocol 1993, Cape Town Agreement 2012, STCW-F 1995 and SOLAS 1974) and domestic law concerning criteria of equipment of fishing vessels. As a result, fishing vessels engaged in coastal and inshore fisheries are exposed to the risk of hypothermia when they are in distress and the criteria of equipment of fishing vessels should be amended to provide the immersion suits in accordance with the revision trend of international conventions.

The purpose of this paper is to describe the situation of everyday life of women and men in Germany and gender related aspects. Therefore social demographical data, presented tv the Office for European Statistics, Luxembourg and by German statistical data, are used. Based on this data the different roles, responsibilities, and social positions of women and men are interpreted in the context of the idea of mainstreaming gender. In comparison to other European countries, especially to the Scandinavian countries, the situation of women in Germany still has to be improved. It is a prevalent problem for women to arrange family life and working career, because the gender-related role-allocation is still an issue. Women, who are involved in looking after children, are significantly less engaged in business life, as for men caring does not make a difference, whether they are employed or not. In addition to this fact women on average earn less than men, especially for women working in higher positions. To improve the situation of women and men the German government has initiated a ‘Gender Mainstreaming Policy’ in 2000 and has taken important legal measures which make it possible to reconcile family-life and gainful employment. For Home Economists there is a need to integrate the gender dimension into a household analytical approach.
