Purpose: The purpose of this study is to find a linkage between mobile bathing services and service learning, and a method to activate mobile bathing services. Method: As a descriptive research, it selected evaluation factors from the aspects of structure, process, and result and analyzed 25-month activities. The data analysis was done with descriptive statistics, t-test, ANOVA, and contents analysis. Result: The mobile bathing services were performed for 67 days during the evaluation period and it was 88.2% of the number of expected activity days. The volunteers participated in the activities were 293 and they provided the service for 124 people. The expense per service provision was 97,771 won. Both recipients and volunteers were highly satisfied with this service. Also, the broadcasting on the activities and awards enhanced volunteers' pride. Conclusion: The mobile bathing services linked with the service program as a part of major course. In particular, the service strengthens problem-solving abilities of nursing students, so it is necessary to develop the mobile bathing services into the service program in pursuit of learning by action.

The ethnic dress of Germany's Black Forest, called Tracht, dates back to the 16th century. Although most people living within the Black Forest do not presently wear Trachten, some persistence in this tradition exists. This study explored the factors that have supported the persistence of the Trachten tradition, specifically related to the wearing and crafting of Trachten by women, in a contemporary society. A qualitative, ethnographic approach was adopted. Data were collected via observations and interviews in the Black Forest. Thematic analyses revealed that the maintenance of the Trachten tradition was linked to varied factors that revolved around the overarching themes of both persistence and change. Interpretations were supported by theory proposing that ethnic dress is not static, but rather, changes across space and time in ways that enable its persistence. The persistence of the Trachten tradition was linked to formalized practice, meaningful identities, and desires to preserve and promote local culture. Additionally, the persistence of the Trachten tradition was fostered by change in the tradition, including the conceptualization of Trachten as a "lived practice" and the negotiation of Trachten authenticity.

In order to control the genetic background noise in QTL mapping, cofactor markers were incorporated in single marker analysis (SMACO) and interval mapping (CIM). A simulation was performed to see how effective the cofactors were by the number of QTL, the number and the type of markers, and the marker spacing. The results of QTL mapping for the simulated data showed that the use of cofactors was slightly effective when detecting a single QTL. On the other hand, a considerable improvement was observed when dealing with more than one QTL. Genetic background noise was efficiently absorbed with linked markers rather than unlinked markers. Furthermore, the efficiency was different in QTL mapping depending on the type of linked markers. Well-chosen markers in both SMACO and CIM made the range of linkage position for a significant QTL narrow and the estimates of QTL effects accurate. Generally, 3 to 5 cofactors offered accurate results. Over-fitting was a problem with many regressor variables when the heritability was small. Various marker spacing from 4 to 20 cM did not change greatly the detection of multiple QTLs, but they were less efficient when the marker spacing exceeded 30 cM. Likelihood ratio increased with a large heritability, and the threshold heritability for QTL detection was between 0.30 and 0.05.

This study aimed to investigate the effect of a young children's happiness program in relation with the Nuri curriculum on young children's happiness and self-esteem. Study subjects included 37 children aged 5 (experimental group 20, comparative group 17) enrolled in A day care center and D day care center located in K district, Seoul. As for the research procedure, an experiment was conducted 48 times in 18 weeks, and the experimental group carried out the children's happiness program linked with the Nuri curriculum. In contrast, the comparative group conducted general activities focusing on the subjects according to the Nuri curriculum. Study results show that there was a significant difference amongst 9 sub-domains related to young children's happiness (health, emotion, immersion, recognition and achievement, parent-child relationship, teacher-child relationship, peer relationship, spirituality, life satisfaction) and 3 sub-domains related to self-esteem (start and spirit of independence, sociality emotionality, academic achievement). Results of this study prove that the children's happiness program in relation with the Nuri curriculum is effective for increasing young children's happiness and self-esteem, and could be used as preliminary data for the possibility of a happiness program in early childhood education settings and happiness education in the future.

One of the fundamental roles of web object navigation is to support what the user wants precisely and efficiently from the enormous web database to the web browser. As long as the web search results are a set of individual lists, it is all right to display each and every web result for the web browser to display a web object one by one. However, in case the search results are a collection of multiple interrelated web objects, then there is a need to represent for a new mechanism for linked web objects at a time. We define a unit of web objects derived from a Steiner tree where the web objects include a set of specific keywords calculated by the weight from which the solutions are extracted. Even if a web object does not include all the keywords, then the related hypertext linked web objects are derived and displayed onto the mobile web browser with meta data in one shot. In this paper, it is applied for the mobile browser that the web contents can dynamically be displayed with Steiner trees until each renewal of the navigation request may be issued. In this paper, a new synchronized mobile browsing method is developed so that the navigating time can drastically be reduced and the web navigating efficiency can be dramatically enhanced without sacrificing memory consumption.

Recently, as a solution to the problem of maintaining system reliability, stability, and quality occurring worldwide, such as activation of smart grid and recognition of super grid and rapid grid interconnection of renewable energy sources HVDC(High Voltage Direct Current) will appear on the front of the electric power system. These concepts are also very important concepts in HVDC systems. When the HVDC system is linked to the existing power system, it is composed of AC/DC/AC conversion device, and these conversion devices are composed of many thyristors. These parts(Devices) are connected in a complicated manner, and they belong to the one with a higher failure rate. However, the problem of establishing the concept of failure rate of HVDC parts directly linked to economic efficiency and the understanding accompanying it are still insufficient. Therefore, in this paper, we establish the meaning of reliability in power system and try to develop a model to analyze and verify the failure rate data of HVDC based on this.
