한국어는 교착어이어서 형태소 분석 없이 품사 부착이 어려울 뿐 아니라 형태소를 분석할 때 다양한 어형 변화가 복원되어야 한다. 이것은 한국어 형태소 분석의 고질적인 문제 중 하나이며, 주로 규칙을 이용해서 해결한다. 규칙을 이용할 경우 주어진 문맥에 가장 적합한 복원을 어려워 여러 형태의 모호성을 생성하며, 이는 품사 부착에 의해서 해결된다. 본 논문에서는 이 문제를 기계학습 방법(Na$\ddot{i}$ve Bayes 모델)을 이용하여 해결한다. 기계학습 모델의 입력 자질은 어형 변화가 발생하는 주변 음절이며 출력 범주는 복원된 음절이다. ETRI 구문 말뭉치를 이용한 실험에서 제안된 형태소 복원 모델을 사용한 형태소 단위의 품사 부착 성능은 97.5%의 $F_1$점수를 보였으며 이 모델이 형태소 복원에 매우 유용함을 알 수 있었다.

Objective : The purpose of this study was to identify independent predictors of mortality and functional recovery in patients with primary intracerebral hemorrhage (PICH) and to improve functional outcome in these patients. Methods : Data were collected retrospectively on 585 patients with supratentorial PICH admitted to the Stroke Unit at our hospital between 1st January 2004 and the 31st July 2008. Using multivariate logistic regression analysis, the associations between all selected variables and 30-day mortality and 90-day functional recoveries after PICH was evaluated. Results : Ninety-day functional recovery was achieved in 29.1% of the 585 patients and 30-day mortality in 15.9%. Age (OR=7.384, p=0.000), limb weakness (OR=6.927, p=0.000), and hematoma volume (OR=5.293, p=0.000) were found to be powerful predictors of 90-day functional recovery. Furthermore, initial consciousness (OR=3.013, p=0.014) hematoma location (lobar, OR=2.653, p=0.003), ventricular extension of blood (OR=2.077, p=0.013), leukocytosis (OR=2.048, p=0.008), alcohol intake (drinker, OR=1.927, p=0.023), and increased serum aminotransferase (OR=1.892, p=0.035) were found to be independent predictors of 90-day functional recovery after PICH. On the other hand, a pupillary abnormality (OR=4.532, p=0.000) and initial unconsciousness (OR=3.362, p=0.000) were found to be independent predictors of 30-day mortality after PICH. Conclusion : The predictors of mortality and functional recovery after PICH identified during this analysis may assist during clinical decision-making, when advising patients or family members about the prognosis of PICH and when planning intervention trials.

Purpose: This study aimed to assess combined effects of early oral feeding after Cesarean section (C/S) under regional anesthesia on bowel function, gastrointestinal complications and surgical recovery. Methods: A systematic literature search was conducted using KISS, RISS, PubMed, CINAHL, EMBASE, CENTRAL and Google Scholar to identify randomized clinical trials comparing early oral feeding (EOF) with delayed oral feeding (DOF) after C/S. Outcome variables were bowel function and gastrointestinal complications and surgical recovery. Effect size was calculated using weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs). Results: Seven studies involving 1,911 patients from 568 studies, 7 studies were included in meta-analysis. EOF was significantly associated with shorter time to recover bowel movement compared with DOF (WMD, - 2.50; CI, - 3.50~- 1.50). EOF was not associated with nausea (RR, 1.15; CI, 0.87~1.53) and vomiting (RR, 0.96; CI, 0.65~1.42), but lower incidence of abdominal distension (RR, 0.70; CI, 0.50~0.98). EOF was significantly associated with shorter time to discontinuation of intravenous fluids (WMD, - 8.88; 95% CI, - 16.65~- 1.11) and removal of urinary catheter (WMD, - 15.23; CI, - 25.62~- 4.85). Conclusion: This meta-analysis provides evidence that EOF after C/S under regional anesthesia not only accelerates return of bowel function and surgical recovery but also reduces gastrointestinal complications. These results suggest that EOF should be offered to women who have undergone C/S to improve the recovery experience and reduce overall medical costs.

The purpose of this research is to study the utility of prediction program like a F.E.M. analysis for energy recovery of heat exchanger with heat pipe which uses arbitrary groove wick. The program is based on the utility by the experimental and applytical method of the single heat pipe. It is also expanded and applied in the prediction program of the heat exchanger. The results are as follows; 1) The effective thermal conductivity of the groove wick with arbitrary shape is counted by the thermal resistance change. 2) The more the number of rows, the more the effect energy recovery changing by the number of rows, the bigger the free velocity, the smaller the effect of energy recovery. 3) The effect of energy recovery increases according to the value of the rate of mass flow (Me/Mc) and also number of rows. 4) The comparison between calculated and data shows good agreement within 2.5% error, therefore the F.E.M. analysis of the study is useful to predict the performance of heat pipe-heat exchanger.

대규모 투자를 통하여 구축된 재해복구시스템(DRS)도 체계적인 운영관리를 소흘히 하면 일정 기간 경과 후에는 최초의 구축 목적을 달성할 수 없는 쓸모없는 시스템으로 전락할 소지가 있다. 또한 재해복구체계는 전산장비의 이중화에 의해서 완성되는 것은 아니다. 재해 시 재해복구시스템 유지를 위해서는 기존 전산센터에서 수행되는 일련의 과정이 동일하게 이루어져야 정상적인 운영이 가능하다. 따라서 IT 측면에서의 프로젝트 추진이 아니고 전산센터 내부에서 이루어지는 전체 프로세스 측면에서 분석 작업이 이루어져야 한다. 더 나아가 전사적인 관점에서 분석하고 설계하는 사업연속성계획 수립이 절실하다. 따라서 국내 금응권 재해복구시스템의 현상 파악을 통하여 실효성을 분석해 봄으로써 문제의 원인과 보완책을 함께 찾아보고자 한다.

Objectives: To describe the progress and influencing factors of Hwa-byung. Methods: Data were collected from semi-structured interviews. The progress of and recovery from Hwa-byung were examined using the collected experiences of eight middle-aged women who suffered from Hwa-byung. For analysis of the data collected, a Consensual Qualitative Research (CQR) methodology was used. Results: Of the eight participants who thought they had Hwa-byung, six were actually Hwa-byung patients and two were non-Hwa-byung patients. Four years later, four of the six Hwa-byung patients recovered, while the Hwa-byung of one patient persisted, and the remaining patient had circular Hwa-byung. Over time, the symptoms of Hwa-byung declined substantially. However, the patients recognized that their disease continuously persisted. Moreover, they thought their symptoms had worsened. Many types of changes were observed during the recovery period, including environmental, physical, cognitive, and emotional changes, as well as changes in attitudes toward others. Recovery factors included the reduction of stimuli, social support, exercise, treatment, control of rumination, and some cognitive changes. Conclusions: To recover from Hwa-byung, it is necessary for patients to experience changes in environment, cognition, and emotion, and to employ self-management in everyday life.

The sulfatation of chitosan, by reaction with chlorosulfonic acid under controlled conditions, allowed increasing the pH range of chitosan solubility. The biopolymer was characterized using FTIR and $^{13}C$-NMR spectroscopy, elemental analysis and titration analysis and it was tested for mercury recovery by polymer enhanced ultrafiltration (PEUF). In slightly alkaline conditions (i.e., pH 8) mercury recovery was possible and at saturation of the polymer the molar ratio $-NH_2$/Hg(II) tended to 2.6. Polymer recycling was possible changing the pH to 2 and the polymer was reused for 3 cycles maintaining high metal recovery. The presence of chloride ions influences metal speciation and affinity for the polymer and "playing" with metal speciation allowed using the PEUF process for mercury separation from cadmium; at pH 11 the formation of hydroxo-complexes of Hg(II) limits it retention. Cake formation reveals the predominant controlling step for permeation flux.

This study is a thermal and flow analysis of Organic Rankine Cycle (ORC) pipe line for 250 kW grade waste gas heat recovery. We attempted to obtain the boundary condition data through the process design of the ORC, which can produce an electric power of 250 kW through the recovery of waste heat. Then, we conducted a simulation by using STAR-CCM+ to verify the model for the pipe line stream of the 250 kW class waste heat recovery system. Based on the results of the thermal and flow analyses of each pipe line applied to the ORC system, we gained the following conclusion. The pressure was relatively increased at the pipe outside the refracted part due to the pipe shape. Moreover, the heat transfer amount of the refrigerant gas line is relatively higher than that of the liquid line.
