The purpose of this study was to categorize the contribution evasion and develop the expected models for contribution arrears in National Health Care System. The modified logistic regression model in non-payments was used as logistic regression model based on the statistical method. By using this model, we arranged non-payment types and typical branches those are appeared by statistical technique. First fact, sex and age branches those are able to take a part in economy had effect mostly. Also they had difference in non-payment probability by existence of their incomes and property. Especially people who didn't have their own house and car were appeared in high non-payment probability, disease and reduction characteristic(rare diseases, reduction of seniors, handicaps, numbers of medical treatments) didn't effect much in probability. The reason for some characteristic of non-payment which is higher than the correct threshold value of Logistic Regression Model (a suggested model for predicting non-payment)'s distribution of probability was mostly moral hazard. Living difficulty was the bigger reason for non-payment, but moral slackening was the bigger reason for non-payment. But it is careless to decide that moral hazard is just the reason, there is a necessity to examine on the side of sociology based in family. By the reason, the member's non-payment reason can be classified by economy, population, and psychology, but there was a comprehension that losing of work desire could be one reason. So we analyzed informations for composition of family of members. In conclusion, we grasped that family conflict makes non-payment and conversion of member in the National Basic Livelihood Protection System difficult.

The purpose of this study is to examine green consumer behavior (green product purchasing behavior and green consumption life) affected by demographical characteristics, and cognition degree of green life (cognition of a green indicator, a green life catalyst system, and environmental problems). It's also to promote strategy and suggest effective activation plans for the vitalization of green consumer behavior. To carry out the task, verification of credibility, multiple regression analysis, two-step cluster analysis, and multinomial logistic analysis were used. The results are as follows: First, the factors that effect green product purchasing behavior were gender, age, cognitive of a green indicator, carbon points system, electricity peak hour system, and seriousness of environmental damage due to lifestyle. Second, the factors that effect green lifestyle were gender, age, carbon grade indicator system, cognition of a green system, and the seriousness of environmental damage due to lifestyle. Third, the comparative group characteristic analysis showed low rates for careless green consumer behavior groups compared to the passive green consumer behavior groups in cognition of a green indicator, green system, and environmental problems. For active green consumer behavior groups, the analysis showed high rates in cognition of carbon grades, eco-labeling, electricity peak hour system, and environmental damage due to lifestyle. In order to encourage green consumer behavior, it's evident that cognition of a green indicator, a green life catalyst system, and environmental problems need to be improved through strategic education and continuous encouragement.

A Hangul input method consists of two core components: key layout for primitive units (Natja), and binding rules to form more complex, composite units from primitive ones. However, careless design and implementation of an input method may result in ambiguity and inability of contiguous typing, when it comes to handle composite Hangul units. This is due to the collective nature of Hangul, namely, existence of implicit boundaries between units and syllables. This issue gets more challenging for the context-dependent 2-beolsik method, mobile environment having significantly fewer keys, and yet addition of the support for Old Hangul. For the sake of the management of complexity, we devised a system in which the binding rule is divided into two layers rather than one. Based on this concept, we implemented a tool program that, given the primitive units and their binding rules, generates input details of every composite unit and detects any potential ambiguity and conflicts. We presented the actual analysis result for Samsung Cheonji-in and KT Naratgeul, two of the most popular mobile Hangul input methods used in Korea.

Objectives: The major objective of this study was to develop a tier 2 exposure model combining tier 1 exposure model estimates and worker monitoring data and suggesting narrower exposure ranges than tier 1 results. Methods: Bayesian statistics were used to develop a tier 2 exposure model as was done for the European Union (EU) tier 2 exposure models, for example Advanced REACH Tools (ART) and Stoffenmanager. Bayesian statistics required a prior and data to calculate the posterior results. In this model, tier 1 estimated serving as a prior and worker exposure monitoring data at the worksite of interest were entered as data. The calculation of Bayesian statistics requires integration over a range, which were performed using a Riemann sum algorithm. From the calculated exposure estimates, 95% range was extracted. These algorithm have been realized on Excel spreadsheet for convenience and easy access. Some fail-proof features such as locking the spreadsheet were added in order to prevent errors or miscalculations derived from careless usage of the file. Results: The tier 2 exposure model was successfully built on a separate Excel spreadsheet in the same file containing tier 1 exposure model. To utilize the model, exposure range needs to be estimated from tier 1 model and worker monitoring data, at least one input are required. Conclusions: The developed tier 2 exposure model can help industrial hygienists obtain a narrow range of worker exposure level to a chemical by reflecting a certain set of job characteristics.

Objectives : Children who are users of local children's centers are mostly in the lower income brackets or raised by single parents or grandparents. Their parents are usually careless about them, or they are placed in tough environments. Specifically, they are unlikely to be taught at home to brush their teeth on a regular basis. The purpose of this study was to examine the oral health education experiences of teachers at local children's centers and the reality of oral health care provided by them to children, and to pave the way for the development of collaborative oral health education programs by local children's centers and local communities. Methods : The subjects in this study were teachers who worked at 158 local children's centers located in Gyeongnam Province. Each teacher was asked to fill out the given a questionnaire at the centers. The survey was conducted by phone or in person from February 26 to April 1, 2009. The collected data were analyzed with SPSS 15.0 program, and statistical data on frequency and percentage were acquired to find out the general characteristics of the teachers. And crosstabulation was utilized to look for connections between oral health education experiences and actual oral health care. Results : At the 158 local children's centers, 21 teachers had ever learned about oral health education to provide children with that, and 137 teachers hadn't. The local children's centers that the former worked for had more interest in dental caries, and those centers had children do toothbrushing more than the other centers at which the latter served. Conclusions : It seems that local children's centers and local communities should make concerted efforts to develop joint education programs.

The railway signalling system plays an essential role in the headway and routing control for a safe and efficient train operation. The reliable and safe operation of the system is very important because the failure of the railway signalling system can lead to the collision, derailment, or unexpected stop of a train. So far, the conventional wayside signal mode (ATS: Automatic Train Stop) has been generally used as the railway signalling system. However, this system is highly linked to a risk of major accidents resulted from human mistakes such as missing a signal or careless control of train speed. Accordingly, the onboard signal mode (ATC: Automatic Train Control) as an alternative of ATS has been recently introduced and applied to transmit effectively the information on speed control of a train by using computers and communication equipment. In the process of replacing the obsolete signal system, it is necessary to switch over the system while providing passengers with normal services. Therefore, the integration of a railway signaling system compatible for both ATS and ATC and its interface is discussed in this study. In particular, the implementation scenario required for operation planning of the integrated system was designed, and the results as well as effects of its applicability test were also presented.

Various studies have been done in medical service area but they have just focused on the examination of the relationships between cause and effect variables. This study, thus, empirically analyzed qualitative data regarding medical service problems using word cloud technique. The major results of the paper are as follows. The data reveal ten sources in medical service - forced treatment, excess inspection, misdiagnosis, carelessness, inexperienced service, waiting for emergency, reservation problem, unkindness, process problem, and inconvenience. Major words in the category of irrecoverable service failure are misdiagnosis, careless treatment, and inexperienced service whereas those in recoverable service failure are unkind attitude and negative experience in reservation system. Those who experienced a medical service problem are usually engaged in a public act and they make public protests and legal action against very severe problems. The conclusion of this study also suggests a summary, implication, and agenda of the research.

Backgrounds: Burn of children and adolescents is an accident due to careless protector in many case. All the pediatric burns are preventable. We investigated the characteristics of pediatric burns. Such data can propose proper health educational program designs to suit the community. Purpose: This study aims to analyse the characteristics of pediatric burn patients and to discusses a possible prevention program for this population. Methods: The subjects were 77 patients reviewed burn injury in pediatric under 15 years old. Data were burn center of the B General Hospital from January 1 to December 31 2009 and a retrospective epidemiological study was collecting medical records. Results: seventy-seven children and adolescents with burn were admission treated for Burns and they were 54.5% boys and 45.5% girls. An incidence of age group with pediatric burn was less than one year of age(46.8%), 2-3 year(27.3%), 4~7year(10.4%), over 8 years old(15.6). Length of stay hospitalization was 1~2 week(32.9%) highest percentage and second-degree deep burns were 41.6% the highest percentage. Divided by the age of about 3, length of stay, ICU status, time of injury onset, cause, indication, place of accident, treatment, degree, region of burns had a statistically significant difference. Conclusion: Less than one year of age was the highest percentage. Divided by the age of about 3, Characteristics and factors affecting the range of burn were significant. Education and guide are necessary to reduce incidence of pediatric burns.

The legislative body of The People's Republic of China, the National People's Congress, enacted the first arbitration act in China's history on August 31st, 1994, which took effect on September 1, 1995. The problems revealed through a comparison of China's Arbitration Act with the UNCITRAL model arbitration law were studied as well as the enacting process, background, status and system, important contents, problems of Chaina's Arbitration Act, and the differences between the old arbitration regulations and the new arbitration act. These are all discussed in this paper. The Arbitration Act is the basic act ruling over china's arbitration system: it unified the previously confusing laws and regulations relevant to the arbitration system, and the act brings out fundamental changes in China's domestic arbitration to the level of international arbitration standards. It is possible to view this act as a cornerstone in China's arbitration system. But, as discussed in this paper, there are still a lot of problems with the new act and only a few of the merits which the UNCITRAL model arbitration law has. First, under China's Arbitration Act, parties enjoy autonomy to some degree, but the range of party autonomy, compared to that of the UNCITRAL model arbitration law, is too narrow. Second, because China's Arbitration Act didn't explicitly provide issues which can give rise to debate, a degree of confusion in its interpretation still remains. Third, China's Arbitration Act's treatment of some important principles was careless. Fourth, in some sections, China's Arbitration Act is less reasonable than the UNCITRAL model arbitration law. These problems must be resolved in order to develop China's arbitration system. The best way of resolving these problems for China is to adopt the UNCITRAL model arbitration law. But it is difficult to expect that China will accept this approach, because of the present arbitration circumstances in China. Although it is difficult to accept all the contents of the UNCITRAL model arbitration law, China's legislators and practitioners must consider the problems mentioned in this paper.
