In this study, a database was established by analyzing the record data research produced in ice hockey sports. The deployed data verification with Ice hockey reference service was demonstrated with ice hockey officials and players. This research utilized the data stored in the KNSU Datanest data repository and developed PDF parsers for batch processing of records. Among the types of records, the game summary, team roster, team statistics, and player statistics files were collected, and tables were extracted from the records. PDF records were converted to text in CSV format which are converted to DataFrame and loaded into the database. Out of the total 22 types of records, 4 types were constructed with OO data parsed as element values. Data verification has found no problems with the quality of the data deployed, showing a high satisfaction with providing 66 factors against the 30 factors provided by the service previously used.

Wins above replacement (WAR) is one of the most widely used statistic among sabermatrics statistics that measure the ability of a batter in baseball. WAR has a great advantage that is to represent the attack power of the player and the base running ability, defensive ability as a single value. In this study, we proposed a hitter ability index using the sabermetrics statistics that can replace WAR based on Korea Baseball Record Data of the last three years (2013-2015). First, we calculated Batter ability index through the arithmetic mean method, the weighted average method, principal component regression and selected the method that had high correlation with WAR.

This study examines the duration and severity of droughts by the use of stochastic process considerations. The key annual flow statistics are used to estimate the related statistics of drought probability distributions for various combinations of return period and water demand. This study efforts initially focused on analyzing all the nation streamgage records that were judged to meet certain selection criteria, including those of record length, record quality. These analyses resulted in the determination of those annual flow statistics necessary to define the behavior of drought sequences for the selected streams. Using prior research results, the actual or estimated flow statistics are related to the probability distributions of maximum drought events, through the application of the theory of runs. This has resulted in assigning return periods to drought events at gaged locations, and permits an assessment of the probabilities of observed historical drought within the nation.

Effectiveness of the video-record learning method in teaching bowel elimination nursing skill was investigated using an experimental research methodology. Data was collected from 63 female students attending Fundamental Nursing class from a nursing college in Seoul. The subjects were randomly assigned to two groups, one is the experimental group of 29 and the other the control group of 34. The independent variable was video-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing elimination skill, and satisfaction about the learning method. The hypotheses of the study were as following. 1) There will be significant difference between the experimental group and the control group in dependent variables. 2) There will be significant positive correlations between nursing skill achievement and other three dependent variables-interest in nursing, adaptation in nursing, and preference of nursing job. Data was analyzed using descriptive statistics, chi-square test, t-test, and Pearson's correlation coefficient with SPSS $PC^+$ program. Findings of the study are : 1) There was no significant difference between the experimental group and the control group in knowledge achievement using P<.05. 2) There was significant difference between the experimental group and the control group in nursing skill achievement using P<.05. 3) There was no significant difference between the experimental group and the control group in competence on practicing elimination skill using P<.05. 4) There was no significant difference between the experimental group and the control group in satisfaction about learning method using P<.05. 5) There was positive correlation between nursing skill achievement and the other variables but no significant difference was shown. 6) This study suggests that video-record learning method is an effective learning method for achiving basic nursing skills but is not effective in other areas such as knowledge achivement, competence in performing nursing practice, and satis-faction about the learning method. Further study with more developed research design and statistical analysis should be done to investigate the effectivenes of video-record learning method in learning basic nursing skill more accurately.

Background : Coding of principal diagnosis is essential component for producing reliable health statistics. We performed this study to evaluate the current practice of principal diagnoses determination and coding, and to give some basic data to improve coding of principal diagnosis. Method : Nineteen medical record administrators (MRAs) of 3 university hospitals participated in coding principal Dx. from August 1, 2001 to August 31, 2001. From each hospital, 10 medical records of patients with high frequency disease were selected randomly. Each 10 medical records were grouped into three (A. B, C). Then, these 30 medical records were given to each MRAs for coding. At the same time questionnaire was given to each of them. Questions were to prove how they decide and code the principal diagnosis among many current diagnoses; how they decide and code the principal diagnosis when they see irrelevant diagnosis recorded as the principal diagnosis in medical record, when only tentative diagnoses were recorded without final diagnosis, and when different diagnoses were recorded in different sheets of same record. Agreement of coding among 3 hospitals were compared and survey results were analysed with SAS 6.12. Results : Agreement of coding was found in medical records 5-6 of each 10 medical records. Causes of disagreement were as follows. Difference of clinician's opinion from each hospital; mixed use of guideline from KCD-3 and guideline from DRG; difference in 4th digit classification according to the absence of pathology report in the medical record; difference of abbreviations among hospitals. 57.9% of MRAs selected the principal diagnosis recorded by physician, 42.1% of MRAs decided principal diagnosis after consulting to KCD-3 guideline. When there were difficulties in determining the principal diagnosis, 42.1% of MRAs decided principal diagnosis after discussion with the physician, 26.3% after discussion with fellow MRAs. Conclusion : There were differences in codings among hospitals. To minimize the difference, we suggest the development of disease-specific guidelines for coding in addition to the current general guideline such as KCD-3. To do this, Coding Clinic which can produce guidelines is needed.

When micro data are released to users, record by record data are disclosed and the disclosure risk of respondent's information is inevitable. Statistical disclosure control techniques are statistical tools to reduce the risk of disclosure as well as to increase data utility in case of data release. In this paper, we reviewed the concept of disclosure and disclosure risk as well as statistical disclosure control techniques and then investigated selection strategies of a statistical disclosure control technique related with data utility. The risk-utility frontier map method was illustrated as an example. Finally, we listed some check points at each step when microdata are released.

Effectiveness of the videotaped-record learning method in teaching intramuscular injection skill was investigated using an experimental research methodology. Data was collected from 57 female students attending Fundamental nursing class from two depts. of nursing in Chung-ju and Seoul. The subjects were assigned to two groups, the experimental group of 30 and the control group of 27. The independent variable was videotaped-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing intramuscular injection skill and satisfaction about the learning method. Data was analyzed using descriptive statistics, chi-square test, t-test and Pearson's correlation coefficient with SPSS-PC program. The results were summarized as follows ; 1. There was statistically significant difference between the experimental group and control group in knowledge achievement about intramuscular injections (t=4.721, P=.000). 2. There was statistically significant difference between the experimental group and control group in nursing skill achievement(t=3.542, P=.001). 3. There was no statistically significant difference between the experimental group and control group in competence on practicing intramuscular injection skill (t=.627, P=.533). 4. There was statistically significant difference between the experimental group and control group in satisfaction about learning method(t=4.708, P=.000). 5. There was significant correlation between nursing skill achievement and knowledge achievement(r=.233, p<.05). In conclusion, this study suggests that videotaped-record learning method is an effective learning method for achieving intramuscular injection skill as a basic nursing skills. Therefore, further study with more developed research design and other fundamental nursing skill practice will be needed to investigate the effectiveness of videotaped-recored learning method.

A stochastic Gompertz diffusion model for tumor growth is a topic of active interest as cancer is a leading cause of death in Korea. The direct maximum likelihood estimation of stochastic differential equations would be possible based on the continuous path likelihood on condition that a continuous sample path of the process is recorded over the interval. This likelihood is useful in providing a basis for the so-called continuous record or infill likelihood function and infill asymptotic. In practice, we do not have fully continuous data except a few special cases. As a result, the exact ML method is not applicable. In this paper we proposed a method of parameter estimation of stochastic Gompertz differential equation via Markov chain Monte Carlo methods that is applicable for several data structures. We compared a Markov transition data structure with a data structure that have an initial point.

Exponential distribution is widely adopted as a lifetime model. Many authors have considered the interval estimation of the parameters of two-parameter exponential distribution based on complete and censored samples. In this paper, we consider the interval estimation of the location and scale parameters and the joint confidence region of the parameters of two-parameter exponential distribution based on upper records. A simulation study is done for the performance of all proposed confidence intervals and regions. We also propose the predictive intervals of the future records. Finally, a numerical example is given to illustrate the proposed methods.
