  • In this paper, firstly we report experimental results on applying information extraction (IE) methodology to the task of summarizing clinical trial design information in focus on ‘Compared Treatment’, ‘Endpoint’ and ‘Patient Population’ from clinical trial MEDLINE abstracts. From these results, we have come to see this problem as one that can be decomposed into a sentence classification subtask and an IE subtask. By classifying sentences from clinical trial abstracts and only performing IE on sentences that are most likely to contain relevant information, we hypothesize that the accuracy of information extracted from the abstracts can be increased. As preparation for testing this theory in the next stage, we conducted an experiment applying state-of-the-art sentence classification techniques to the clinical trial abstracts and evaluated its potential in the original task of the summarization of clinical trial design information.

  • The domestic law establishes a sea trial prohibited area and stipulates that a sea trial is prohibited in this area. However, depending on the user, the term is used interchangeably with on-board test after repaired, In particular, ships undergoing test called a sea trial after remodeling and repairing ships at repair shipyards do not comply with these regulations. By this study, we would like to look at the relevant laws and regulations to see if these ships can be interpreted as sea trial, and suggest the necessity of managing repaired test ships with risks comparable to those of sea trial ships.

  • Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.

  • Reinforcement learning is a learning method that uses trial-and-error to perform Learning by interacting with dynamic environments. It is classified into online reinforcement learning and delayed reinforcement learning. In this paper, we propose an online reinforcement learning system (ONRELS : Outline REinforcement Learning System). ONRELS updates the estimate-value about all the selectable (state, action) pairs before making state-transition at the current state. The ONRELS learns by interacting with the compressed environments through trial-and-error after it compresses the state space of the mage environments. Through experiments, we can see that ONRELS can search the shortest path faster than Q-learning using TD-ewor and $Q(\lambda{)}$-learning using $TD(\lambda{)}$ in the maze environments.

  • The methodology to design initial blanks considering the reduction of both springback and flange trimming amounts is studied. Three dimensional forming analysis of a trial blank Is first carried out using FEM and the tentative Initial blank shape is then determined by cutting the outer edge of the trial blank whose shape is nearly matched with the trimming line. During the shaping the blank edge, tile movement of blank outer line is described with random variables to reduce the sensitivity of initial blank geometry. After performing 2-D FEM forming and springback simulations for selected sections and optimizing the trimming and springback amounts in terms of section length of the blank, the initial blank is finally determined. In order to see tile springback reduction in the initial blank determined by the proposed method, a stepped s-rail is stamped and the sppingback is measured. The springback of newly designed initial blank of stopped s-tail is tremendously reduced.

  • The design analysis of axisymmetric, multi-stage deep drawing dies was performed using the rigid-viscoplastic finite element formulation. In the formulation, the axisymmetric CFS algorithm was employed. Hill's non-quadratic normal anisotropic yield criterion and isotropic hardening rule were considered. For trial initial displacements and tool contact points, the geometric force equilibrium method was adopted. In order to see the validity of the formulation, the multi-stage deep drawing processes of shell-cylinder front part of hydraulic booster were simulated. The simulation showed good agreements with measurements and PAM-STAMP.

  • Objectives : It is known that abdominal obesity increases the possibility of cardiovascular diseases, early death, and metabolic syndrome including dyslipidemia and insulin resistance. Clinical trials have been under way to verify the effectiveness of treatment for abdominal obesity. The objective of this study is to set criteria about how effective oriental medicine and acupuncture are in abdominal obesity. Methods : I manually search "www.clinicaltrial.gov", 4 Korean medical databases and 4 Korean medical journals of abdominal obesity. Search terms used were "abdominal obesity" or "visceral obesity". In order to see detail review, searching was performed from 01, 01, 2005 to 11, 31, 2009. And I classified all the searched studies into design, intervention, purpose, end point, diseases, condition and etc. Results : 1. I could search total 67 trials in "www.clinicaltrial.gov". I found 9, 10, 13, 8, 6 clinical trial from 2005 to 2009 every year. 2. Test on both gender and adult or adult and senior have been most frequent. 3. Randomization clinical trial is 51 cases that occupied 96.2%. 38 cases use control group. 4. Body mass index(BMI) and waist circunference(WC) are major criteria of abdominal obesity clincal trial. WC, BMI, abdominal fat mass, body weight are measured at end point of abdominal obesity clincal trial. 5. I could search total 86 cases in domestic study. I found 15, 23, 23, 20, 5 cases from 2005 to 2009 every year. 6. Test on female and adult have been most frequent in domestic study. 7. Randomization clincal trial is only 2 cases that occupied 2.3%. 62 cases use control group in domestic study. 8. BMI, body fat percent, WC, visceral-subcutaneous fat ratio(VSR), waist-hip ratio(WHR) are criteria of abdominal obesity clincal trial in domestic study. WC, BMI, abdominal fat mass, body weight are measured at end point of abdominal obesity clincal trial in domestic study. Conclusions : To improve abdominal obesity study in traditional korean medicine, it is need to activate clinical trial, meta analysis, develope of clinical practice guidelines, co-works with conventional medicine and etc.
