This study investigated the demand of nutrition education programs among preschooler's parents. Focus group interview was conducted four times with 29 parents of preschool children. Most subjects appeared to have interest in nutrition education; 'very interested' (58.6%), 'somewhat interested' (20.7%). Sources of nutrition information were 'internet' (35.1%), 'books' (21.6%), 'newspaper or magazines' (13.5%), 'family or relatives' (13.5%), 'media' (8.1%), 'preschool' (5.4%) and 'hospital or public health center' (2.7%) in order. The most frequently mentioned health problems related to dietary behavior were atopy and obesity. Major concerns for children's dietary behavior was picky eating habits, and having questions for how to deal with this problem. Most subjects had trouble with obtaining an adequate amount of dietary supplements for their children. Nutrition education for parents about food labeling and information on processed foods was in demand. Preferred methods of nutrition education for children were playing games with stickers, gardening vegetables, and participating in cooking. Attitudes toward computer-assisted education materials, one of the methods of nutrition education, appeared to be ambivalent. Some preschool parents showed negative attitudes towards exposing their children to electronic devices at an early age, whereas others showed positive attitudes. Subjects were interested in meal-planning and ways to balance nutrients for their child. Parents preferred attending professional lectures to receive reading materials or searching websites as an adult nutrition education method. Results of this study have implications on providing basic information for developing nutrition education programs for preschoolers and their parents. Future research should focus on developing nutrition education programs for both preschools and the home.

Unrecorded fern species of Korean flora, Thelypteris interrupta (Willd.) K. Iwats. (Thelypteridaceae) and Dryopteris subexaltata (H. Christ) C. Chr. (Dryopteridaceae), were collected from Jeju island off the south coast of Korean peninsula and reported here. T. interrupta is most similar to T. acuminata (Houtt.) C. V. Morton in morphology, however, the two species are readily distinguishable by the plant color including rhizome, stipe base and spore, and the presence of glandular hair as well as the distribution pattern of sorus on lower leaf surface. D. subexaltata is also well distinguishable from its relatives, D. sparsa (D. Don) Kuntze, D. sabaei (Franch. & Sav.) C. Chr., and D. yakusilvicola Sa. Kurata by the presence of proliferation, shape of pinnae, distribution pattern of sori on lower leaf surface, and shape of indusium.

Objective Weight change in the postpartum period is a dominant concern of new mothers recently. Postpartum weight retention has important public health implication as well, because retention of gestational weight can be a significant contributor to long-term obesity and associated health risks. This study was designed to collect the latest papers and find more effective approach for postpartum obesity. Methods We searched 81 papers in English from PubMed and selected 41 in favor of our study. In addition to that, we searched 11 papers in Korean and 2 papers in Chinese. Results are as follows. Results and Conclusions These papers show that many different factors were related with postpartum weight retention. This study suggests that moderate weight gain during pregnancy is important to prevent postpartum obesity. Adequate caloric restriction and exercise are needed to prevent from postpartum weight retention. In addition, husbands, some relatives and friends are primary sources for postpartum female to lose and keep up weight. The effect of weight loss associated with lactation significantly differs from paper to paper. There are not many treatments for postpartum weight retention. So, more effective treatments using Korean traditional medicine must be improved even from now on. This study can offer many ideas to treat postpartum weight retention.

This paper describes a Q-methodological study on the Perception of comfort in hospital in-patients. The participants completed a 37-item Q sort made up of statements which could be ranked in terms of their relevance to the subjective meaning of comfort. Three interpretable types of comfort were identified through this Q study : Type I, positive medical action style, feel secure and satisfied when medical staff show a positive attitude towards them as patients. They put a high value on prompt responses from medical staff and physical aspects of care like non-invasive procedures or comfortable position. Type II, social relation style, experience a state of comfort when they perceive support or concern from medical staff, relatives or other patients suffering from similar diseases. They feel safe and secure when medical staff are kind and have a good reputation or when the size of the hospital is big enough, Type III, emotional wellbeing style, feel that hope for a healthy life or maintaining self-care activities are highly valuable. They feel safe and comfortable when their privacy is protected. They put worth on independent thinking, strong will, and emotional or psychological comfort. The results of this study can be used as a basis to develop nursing measures for comfort. Further studies on factors which influence perception of comfort and intervention strategies according to the above types of comfort need to be done.

The social activities of the elderly are important in successfully achieving aging by providing opportunities for social interaction to enhance life satisfaction. The purpose of this study is to identify the related factors of the elderly social activities and build a statistical classification model to predict social activities. Subjects were 1,864 elderly people (829 males, 1,035 females) who completed the community health survey in 2015. Outcome variables were defined as the experience of social activity during the past month(yes, no). The prediction model was constructed using decision tree model based on Classification and Regression Trees (CRT) algorithm. The results of this study were subjective health, frequency of meeting with neighbors, frequency of meeting with relatives, and living with spouse were significant variables of social participation. The most prevalent predictor was the subjective health level. In order to prepare for the successful aging of the super aged society based on the results of this study, social attention and support for the social activities of the elderly are required.

The purpose of this research is to study the middle and high school student’s value on the family life of the contemporary society. The data for this study has been collected for 808 students of kangwon-do by Liert-scale Type questionnaire. The data were processed by SPSS-X Program. Frequency, Percentage, Mean, Standard Deviation, One-way ANOVA, Pearson’r coefficient, Step-wise multiple regression and Cronbach’coefficient have been calculated and analyzed. The Summary of this research is described as follows. Firstly, the overall average of value of family life was 3.25 points which reflected more or less modern tendency. Secondly, significant difference in the student’s value of family life affected by environmental variables were such as sex(P<.001) school years(P<.001) group(P<.01). Thirdly, the overall average of the student’s interest in the home economics was 3.74 points which reflected heigher tendency, Significant difference in the student’s interest in the home economics according to environmental variables were such as sex(P<.001) school years(P<.05), living standard(P<.01), residential area(P<.001). Fourthly, the student’s overall interest in the home economics and their view on the family life were correlated as follows; Spare time(r=-1.3), parents-children(r=.12) relatives and neighbors(r=0.8) show lower correlation and household work(r=.07) show higher correlation. Fifthly, the area which has closest correlation with the value on the family life was the value on family economics, whereas is has been shown that the field with least correlation was the area of supporting the spare time. Sixthly changes that affect the student’s value of the family life were such as sex (${\beta}$=.43), school years(${\beta}$=.18), group(${\beta}$=.15) and interest degrees(${\beta}$=-.12). These whole explanatory power was 21%.

The purpose of this study is to suggest how the first birthday rite, a practice in Korean culture, has changed over the time. A survey of 250 mothers was undertaken from October 11th to November 6th, 2012. The research questions asked in this study are as follows. What general and expert views are held about the first birthday rite? What type of awareness and knowledge do mothers have about the first birthday rite? Is there any correlation between mothers' awareness and knowledge about first birthday rite? What is the importance of the components of the baby's first birthday rite and the importance of choosing first birthday rite goods? The data were analyzed using SPSS 17.0. Frequency, F-test, correlation were also employed. The results of this study are as follows: The first birthday rite shows a clear link to socializing. It is a family event, but is also seen as an opportunity to enhance relationships with relatives, colleagues, and friends. A banquet hall is chosen as preferred first birthday rite location, and participants are served a meal and receive gifts. The banquet information on first birthday rites was initially collected from the internet, blog cafes, and an experienced. However, it has become gradually more common to hire a consultant to organize the first birthday rite. Awareness of the first birthday rite is high, but knowledge is relatively low. In addition, there is a positive relationship between awareness and knowledge about the first birthday rite. When mothers are preparing for their baby's first birthday, they consider food for the guests' banquet, space and time. Finally, individual positive relationships were found between choosing first birthday rite goods and employee services, contract pricing for goods, and food for guests.

Originally, ancestral rites is a ceremony to pay filial piety to ancestors continuously even though they died, and this is a startingpoint based on the thought of paying respect to ancestors and 'root consciousness' which Korean people have. In the earliest days, Korean people worshipped nature and the sacrificial rituals were performed mainly for the fods of the skies and the earth. After the end-Koryeo Era introduced [Juja-Garye]ancestrial rites of forefather in home generalized. By the way, the foods for ancestrial rites on the original literature centering the [Sa-Rye-Pyon-Ram]are as follows: raw meat(saeng: 牲), rice and broth(ban, gaeng: 飯羹), fruits(果), slice meats(po: 脯), salted dry fish(jaban(佐飯), rice punch(sikhye: 食醯), soup(tang: 湯), fish and meat, roasts beef (jeok: 炙), roast vegetable(sookchae: 熟菜), rice cake(pyon: 餠), noodles(麵), soy(醬), Kimchi(沈菜), drink(酒), green tea(cha: 茶) etc. Today, ancestral rites, basically with this conception, has a function to bind the family and relatives as one. But as double income family are increasing, most housewives have heavy burden mentally and financially to prepare the food for the ancestral. The foods for ancestral rites can be said a way to express the internal true heart, and a basic medium to practice the filial piety. Many documents let us know that a few days before the ancestral rites, we should prepare the food for it with careful and pious attitude. And, they stress that our sincere attitude in preparing food is important rather than its quantity. In this industrial society, we have lots of difficulty preparing and observing the same service as it in the traditional socity. But I think that housewives can be freed from the burden they have to some degree when they realize what the true meaning of ancestral rites is and that the food for it plays a role an external expression.

Inbreeding is the mating of relatives that produce progeny having more homozygous alleles than non-inbred animals. Inbreeding increases numbers of recessive alleles, which is often associated with decreased performance known as inbreeding depression. The magnitude of inbreeding depression depends on the level of inbreeding in the animal. Level of inbreeding is expressed by the inbreeding coefficient. One breeding goal in livestock is uniform productivity while maintaining acceptable inbreeding levels, especially keeping inbreeding less than 20%. However, in closed herds without the introduction of new genetic sources high levels of inbreeding over time are unavoidable. One method that increases selection response and minimizes inbreeding is selection of individuals by weighting estimated breeding values with average relationships among individuals. Optimum genetic contribution theory (OGC) uses relationships among individuals as weighting factors. The algorithm is as follows: i) Identify the individual having the best EBV; ii) Calculate average relationships ($\bar{r_j}$) between selected and candidates; iii) Select the individual having the best EBV adjusted for average relationships using the weighting factor k, $EBV^*=EBV_j(1-k\bar{{r}_j})$ Repeat process until the number of individuals selected equals number required. The objective of this study was to compare simulated results based on OGC selection under different conditions over 30 generations. Individuals (n = 110) were generated for the base population with pseudo random numbers of N~ (0, 3), ten were assumed male, and the remainder female. Each male was mated to ten females, and every female was assumed to have 5 progeny resulting in 500 individuals in the following generation. Results showed the OGC algorithm effectively controlled inbreeding and maintained consistent increases in selection response. Difference in breeding values between selection with OGC algorithm and by EBV only was 8%, however, rate of inbreeding was controlled by 47% after 20 generation. These results indicate that the OGC algorithm can be used effectively in long-term selection programs.

Background: The expression of MMP genes has been demonstrated to be associated with tumor invasion, metastasis and survival rate for a variety of cancers. The functional promoter polymorphism MMP-2 C-735T is associated with decreased expression of the MMP-2 gene. The aim of present study was to detect any association between MMP-2 C-735T and susceptibility to breast cancer. Materials and Methods: The MMP-2 C-735T polymorphism was studied in 233 women (98 with breast cancer and 135 healthy controls). All studied women were from Kermanshah and Ilam provinces of Western Iran. The MMP-2 C-735T polymorphism was detected using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: The frequencies of MMP-2 CC, CT and TT genotypes in healthy individuals were 59.3, 38.5 and 2.2%, respectively. However, in breast cancer patients, only CC (71.4%) and CT (28.6%) genotypes were observed (p=0.077). In patients the frequency of the MMP-2 C allele was significantly higher (85.7%) compared to that in controls (78.5 %, p=0.048). The presence of C allele of MMP-2 increased the risk of breast cancer by 1.64-fold [OR=1.64 (95%CI 1.01-2.7, p=0.049)]. The frequency of MMP-2 C allele was also higher in patients ${\leq}40$ years (88.9%) than those aged ${\geq}41$ years (67.5%, p=0.07). In addition, the frequency of MMP-2 C allele tended to be higher in patients with a family history of cancer in first-degree relatives (76.6%) compared to that without a family history of cancer (67.3%, p=0.31). Conclusions: Our findings indicate that the C allele of MMP-2 C-735T polymorphism is associated with increased risk of breast cancer. Also, the MMP-2 C allele might increase the risk of young onset breast cancer in our population.
