A real $m{\times}n$ matrix A is called an L-matrix if every matrix in its qualitative class has linearly independent rows. Since the number of the sign pattern matrices of the given size is finite, we can list all patterns lexicographically. In [2], a necessary and sufficient condition for a matrix to be an L-matrix was given. We presented an algorithm which decides whether the given matrix is an L-matrix or not. In this paper, we develope an algorithm and C-program which will determine whether a given matrix is an L-matrix or not, or an SNS-matrix or not. In addition, we have extended our algorithm to be able to classify sign-pattern matrices, and to find barely L-matrices from a given matrix and to list all $m{\times}n$ L-matrices.

In these days, the PCs are widely used in the mid-level factory. But they have low-effectiveness for using them. The main reason should be the lack of useful and practical software in the market. This Case study aimed at the support of the software using DB Language to get M/M chart for aquiring work study and standard time data in the mid-level factory having multi-item and multi-process type. CVA (Chronocycle Video Analysis) is applied to get basic standard time data and working list. Standard time, Sequence of working and allowance time or rate for man and machine will be readily obtained through the menu when the software executing. Detailed program list is systematically shown in Appendix.

We find all P-resolutions of quotient surface singularities (especially, tetrahedral, octahedral, and icosahedral singularities) together with their dual graphs, which reproduces (a corrected version of) Jan Steven's list [Manuscripta Math. 1993] of the numbers of P-resolutions of each singularities. We then compute the dimensions and Milnor numbers of the corresponding irreducible components of the reduced base spaces of versal deformations of each singularities. Furthermore we realize Milnor fibers as complements of certain divisors (depending only on the singularities) in rational surfaces via the semi-stable minimal model program for 3-folds. Then we compare Milnor fibers with minimal symplectic fillings, where the latter are classified by Bhupal and Ono [Nagoya Math. J. 2012]. As an application, we show that there are 6 pairs of entries in the list of Bhupal and Ono [Nagoya Math. J. 2012] such that two entries in each pairs represent diffeomorphic minimal symplectic fillings.

Background : Most hospitalized children will experience physical pain as well as psychological distress. Painful procedure can increase anxiety and fear of pediatric patients and their parents who do not have understanding logical of their disease and hospitalization. This study attempted to identify pain reduction in related to therapeutic intervention by age and environmental improvement. Methods : A total of 194 hospitalized children and their parents were investigated. Data collection period was 3 months from March to May 2004. Four instruments were used to collect the data : Faces Pain Rating Scale(FPRS), Heart rate, Oxygen saturation and Pain behavioral check list. The data were analyzed by a SPSS program and tested x2-test, t-test, ANCOVA. Results : 1. Age from 0 to 3, the Heart rate, FPRS, Oxygen saturation and Pain behavioral check list were significantly different in theraputic intervention group when compare to control group. 2. Age from 4 to 6, FPRS, Oxygen saturation and Pain behavioral check list were significantly different in theraputic intervention group when compare to control group. But the heart rate were not significantly different when compare to control group. 3. Age from 7 to 9, FPRS and Pain behavioral check list were significantly lower in therapeutic intervention group when compare to control group but Heart rate and Oxygen saturation were not significantly different when compare to control group. Conclusion : The results of this study concludes that most children experience acute pain during IV therapy and it can be reduced by age specific therapeutic intervention and by change of surrounding environment.

In this paper, I describe the implementation of the distributed lists based on socket and on RMI(Remote Method Invocation). First, I describe and implement an interface of distributed list based on socket using object stream in a distributed environment, when encapsulating the message in the distributed list. Second, the major purpose to implement a distributed list in RMI is to compare advantages and disadvantages with other networking mechanisms by implementing complicated applications. The major advantage in using RMI is to implement simply the programs without using application-level protocol. In terms of program efficiency, the applications using HMI can degrade the performance due to many TCP/IP connections generated every update. TCP/IP connection requires much less cost than RMI. Even though RMI has the mechanism processing many method calls using a sing]e network connection, RMI is less efficient than the direct use of socket. However, RMI makes it possible to communicate beyond firewall using HTTP proxying mechanism. Consequently, I present a modeling of networking mechanism in finding out optimization solution by comparing and analyzing the two systems.

This study aimed to find the association between geographic proximity and program participation at a Healthy Family Support Center (HFSC). Drawing demographic and geographic information from the participant list at a local HFSC in Seoul for the period 2009 to 2011, this study calculated the geographic distance from the individual residence to the center for 2,343 participants. We found that single time participants had a longer distance from their residence to the center than multiple time participants. When we compared the proximity by program areas, we found that the geographic distance to the center was shorter among education program participants than among non participants. However, there was no difference in the other areas of programs. In terms of the target group, the distance was shorter among adult program participants. Finally, the average distance among participants in multiple session programs was shorter. The results of this study indicated that the relationship between geographic proximity and program participation depended on program areas, target groups, and the number of sessions.

A nutrition education program has been designed for the children of obese or unbalanced dietary habits. A total of 120 children(60-obese and 60-unbalanced dietary habits) who were in 5th-6th grade was chosen for the program and the effectiveness of the nutrition education was evaluated. The nutrition education program was organized into daily lessons(3 wks). A booklet was made for the education and used during the education period, dealing with 5-Basic Food Groups and their functions, excess or deficiency in a human body, food exchange list, importance of health, obesity, unbalance dietary habits and of school lunch program were emphasized in every day session. dietary recall records were collected to assess their daily food intake and the amounts of meals were discussed. During the education period, booklets, wall charts, photographs, food models, VTR films and slide films were utilized. Assessment of effects of the nutrition education program was carried out by a nutrition knowledge test, food habit records, anthropometric measurements and food preference test. The nutrition knowledge scores were significantly improved after the education and the scores were higher on the children in the school with school lunch program. The anthropometric measurements and food preference test revealed no significant influences of the education on the children, showing that the education period was too short to change their eating behavior any may need a long-term education program. Food habit scores were improved after the education in both experimental and control groups. The experimental groups showed higher scores than the control group.

Purpose: The purpose of this study was to develop a play education program to reduce children's fear of needle insertion to the implanted port, and to assess the effect of this program. Method: The play education program was composed of play education before needle insertion, encouragement during needle insertion, and a present to reward then after needle insertion. Measurement instruments were the Procedure Behavior Check List(PBCL) and Faces Rating Scale(FRS). Results: The first hypothesis, "the PBCL point of children with malignant disease would decrease after play education program", was rejected(before insertion : Z=-0.189, p= .850, during insertion : Z=-0.350. p= .727, after insertion : Z=-0.590, p= .555). The second hypothesis, "the FRS point of children with malignant disease would decrease after play education program education", was rejected(observer 1 : Z=-0.245, p= .806, observer 2 : Z=-0.912, p= .362, self-report : Z=-0.181, p= .856). The third hypothesis, "the Time of needle insertion would decrease after play education program", was rejected(Z=-0.464, p= .642). Conclusion: The effect on fear-reduction of play education program for children with malignant disease inserted implanted port was not significant but continuous education is needed for parents and children.

Objectives: The purpose of this article is to develop steering of program accreditation system in Korean Medicine Education through meta-evaluation. For this study, the subjects of our research were categorized as the accreditation criteria and system, results and effects, tasks for improvement on Korean Medicine Education. Methods: We conducted Focus Group Interview on 102 full-time professors with experience of participating on accreditation of Korean Medicine Education from 12 college of Korean Medicine Education and we analyzed it by thematic analysis. Results: The accreditation criteria and program evaluation system of Korean Medicine were listed as 'Confusion about the goals of program evaluation', 'High hurdles on accreditation', 'obsession to success cases', 'Small college complaints about applying the same criteria', 'Dilemma of quantitative and qualitative evaluation'. The results and effects of program evaluation in Korean Medicine Education were listed as 'Establishment of base infrastructure for basic medical education', 'Benchmarking and exchanging opinions through evaluation certification', 'Resistance to documents and document-based evaluation', and 'Double-sided of evaluation certification'. As for the tasks for further improvement, the following list is suggested. 'Actively promote evaluation certification', 'Simplification and standardization of forms', 'Requesting for activating about Evaluation committee', 'Need for consulting before regular evaluation'. Conclusion: It is necessary to upgrade the accreditation system and make efforts to improve the issues discovered for better Korean Medicine Education.
