We in this paper propose a mobile application for supporting medical treatment based on Korean medicine ontology. It has three processes for treating patients. First, after a pattern is decided for patient' symptoms, a formula for the pattern is selected and medicinal materials constituting the formula is added or removed. Second, formulas are searched and prescribed for patient's symptoms without the process of the pattern decision. Third, after medicinal materials are searched for patient's symptoms, formulas consisting of the medicinal materials are prescribed. Our application aims to help korean medicine doctors treat patients through providing decision supporting functions such as the recommendation of symptoms of diseases accompanying patient's symptom. Doctors generally diagnosis patients according to their experiences and knowledges. Nevertheless, our application can help them, providing diverse forms of information that they may miss in the medical treatment.

Recently, the use of a recommendation system and tensor data analysis, which has high-dimensional data, is increasing, as they allow us to analyze the tensor and extract potential elements and patterns. However, due to the large size and complexity of the tensor, it needs to be decomposed in order to analyze the tensor data. While several tools are used for tensor decomposition such as rTensor, pyTensor, and MATLAB, since such tools run on a single machine, they are unable to handle large data. Also, while distributed tensor decomposition tools based on Hadoop can handle a scalable tensor, its computing speed is too slow. In this paper, we propose S-PARAFAC, which is a tensor decomposition tool based on Apache Spark, in distributed in-memory environments. We converted the PARAFAC algorithm into an Apache Spark version that enables rapid processing of tensor data. We also compared the performance of the Hadoop based tensor tool and S-PARAFAC. The result showed that S-PARAFAC is approximately 4~25 times faster than the Hadoop based tensor tool.

Many developers utilize specific APIs to develop software, and to identify the use of a particular API, a developer can refer to a website that provides the API or can retrieve the API from the web. However, the site that provides the API does not necessarily provide guidance on how to use it while it can be partially provided in many other cases. In this paper, we propose a novel system JACE (Java AST collocation-pattern extractor) as a method to reuse commonly-used code as a supplement. The JACE extracts the API call nodes, collocation patterns and analyzes the relations between the collocations to extract significant API patterns from the source code. The following experiment was performed to verify the accuracy of a defined pattern: 794 open source projects were analyzed to extract about 15M API call nodes. Then, the Eclipse plug-in test program was utilized to retrieve the pattern using the top 10 classes of API call nodes. Finally, the code search results from reference pages of the API classes and the Searchcode [1] were compared with the test program results.

Data mining is the process of extracting hidden patterns from collected data. At this time, for collected data which take important role as the basic information for prediction and recommendation, the process to discriminate incorrect data in order to enhance the performance of analysis result, is needed. The existing methods to discriminate unexpected data from collected data, mainly relies on methods which are based on statistics or simple distance between data. However, for these methods, the problematic point that even meaningful data could be excluded from analysis due that the environment and characteristic of the relevant data are not considered, exists. This study proposes a method to endow human heuristic knowledge with weight value through the comparison between collected data and human heuristic knowledge, and to use the value for creating a decision tree. The data discrimination by the method proposed is more credible as human knowledge is reflected in the created tree. The validity of the proposed method is verified through an experiment.

The object of this study was to obtain acute information single oral dose toxicity of Mahwangbujaseshin-tang extracts, with mouse bone marrow cell micronucleus test for detecting possible genotoxicity. In order to observe the 50% lethal dose, approximate lethal dosage, maximum tolerance dosage and target organs, test articles were once orally administered to ICR mice at dose levels of 2000, 1000, 50 mg/kg according to the recommendation of KFDA Guidelines. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after dosing according to KFDA Guidelines with organ weights of 12 types of principle organs. In addition, after twice oral treatment of Mahwangbujaseshin-tang extracts 2000, 1000 and 500 mg/kg, we checked the changes on the number of MNPCE. We could not find any mortality, clinical signs, changes in the body weight and gross findings upto 2000 mg/kg treated group. The limited dosages in rodents except for increases of lymphoid organ weights and hypertrophy encounted as results from pharmacological effects of Mahwangbujaseshin-tang extracts, immune modulator effects with some sporadic accidental findings not toxicological signs. No evidence of increases of MNPCE numbers were also detected in all three different dosages of Mahwangbujaseshin-tang extracts treated mice. The results obtained in this study suggest that the LD50 and ALD of Mahwangbujaseshin-tang extracts in mice were considered as over 2000 mg/kg because no mortalities were detected upto 2000 mg/kg that was the highest dose recommended by KFDA and OECD. And the results of mouse bone marrow micronucleus test of Mahwangbujaseshin-tang extracts is negative results.

The object of this study was to obtain acute toxicity information (single oral dose toxicity) of lyophilized water extract of Puerariae Radix (PR) in both male and female mice. In order to investigate the 50% lethal dose $(LD_{50})$, approximate lethal dosage (ALD), test substances were once orally administered to female and male ICR mice at dose levels of 2000 and 0 (control) mg/kg (body wt.) according to the recommendation of KFDA Guidelines [2005-60, 2005]. The mortality and body weight changes, clinical signs and gross observation were monitored during 14 days after dosing. Organ weight and histopathology of 12 principal organs were measured. As the results, we could not find any mortality, clinical signs, body weight changes and gross findings except for PR extracts unrelated sporadic findings. In addition, no abnormal changes related PR extracts treatment on the organ weight and histopathology of principal organs were detected except for some sporadic findings including hyperplasia of lymphoid follicles in the popliteal lymph nodes and spleen as pharmacological effects of PR extracts. The results obtained in this study suggest that the PR extracts does not cause any toxicological signs except for pharmacological effects of enhancement of Immune system. The $LD_{50}$ and ALD of PR extracts in both female and male mice were considered as over 2000 mg/kg because no mortalities were detected up to 2000mg/kg that was the highest dose recommended by KFDA and Organization for Economic Co-Operation and Development.

The objective of this study is to analyze characteristics of high sodium intaker and factors affecting sodium intake using the Korea National Health and Nutrition Examination Survey (KNHANES). For this study we used two statistical methods, the cluster analysis and one-way analysis of variance (ANOVA). Cluster analysis was used to classify groups of sodium intake. For the analysis of the factors affecting sodium intake, we applied the ANOVA. The average daily intake for Korean is about 3,783 mg sodium per day; this amount is high than recommendation of the WTO. The demographic characteristics of people with higher sodium intake were found to be men more so women, and younger men with a higher education. Height, weight and size of a person's waistline were also characteristics of those with higher sodium intake. Also worker, smoker, those without a hypertension diagnosis, as well as those with a higher the drinking rate and higher eating out frequency tended to have a higher intake of sodium. The Ministry of Food and Drug Safety (MFDS) had established a plan to reduce sodium intake to 3,500 mg per day to 2020. To achieve this goal, it is necessary to educate people about high sodium intake, particularly those at higher risk, according to the results of this study. Through these efforts, the social costs of high sodium intake could be reduced, improving national health.

Previous studies reported that gifted students' capacity on mathematics had high correlations with results of the performance assessment. However, there have been few studies that develop recommending tools through the assessment that can be used to identify mathematically gifted students or analyse their applications. Then it is difficult to use them to identify mathematically gifted students practically. Therefore, this study developed the tasks and evaluation tables for the tools. And one of them was applied for four students in Grade 1 of a middle school to simulate the assessment and characteristics assessment teachers showed were analysed. As the results, the extensive and specific information on the giftedness of the students was obtained through using the tool. The gifted capacity grasped from the order, speed, and attitudes of problem-solving was identified as observing the process of solving the task.

Environmental pressures from such sources an economic condition, the government and inter-institutional competition create managerial challenges. Economic pressures may be forcing dietetic dept, in hospital to utilize cost∙benefit analysis to assist them in their problem solving. Cost∙benefit analysis have been widely used in business, industry and many other fields with only limited application to foodservice. Due to the lack or this information the purposes of this study were to identify use of cost∙benefit analysis in hospital foodservice system to evaluate the economic efficiency of alternatives, and to make recommendation for operation system change. Using the cost∙benefit method, cash flows are separated into cost and benefits. For an alternative to be selected, indicators, such as NPV, benefit-cost ratio (B/C ratio) with 5% discount rate per annum. The sensitivity analysis was also conducted with difference rate 3%, 7% respectively and reduced employee payroll change. The result of this study can be summarized as follows : 1. The total cost of investment for operation system change was 390,570 thousand won and the total benefit through operation system change was 865,808 thousand won. 2. Net present value(NPV) for 5 years was 475,239 thousand won and benefit-cost ratio was 2.22. 3. In sensitivity analysis with different discount rate 3%, 7%, benefit-cost ratio was 2.25, 2.18 respectively, with total reduced employee payroll change, benefit-cost ratio was 2.86. In conclusion, total benefits were exceeded total costs. Therefore, the project of operation system change in hospital foodservice was found to be economically efficient.
