웹 문서 정보 서비스는 관리자의 효율적 문서관리와 사용자의 문서검색 편의성을 위해 문서 분류 시스템을 필요로 한다. 기존의 문서 분류 시스템은 분류하고자 하는 문서 내 선택된 자질어의 개수가 적거나, 특정 범주의 문서 비율이 높아 그 범주에서 대부분의 자질어가 선택되어 모델이 생성된 경우 분류 정확도가 저하되는 문제점을 가진다. 이러한 문제점을 해결하기 위해 본 논문에서는 'Modified ECCD' 기법 및 '문서별 범주 가중치' 특징 변수를 사용한 문서 분류 시스템을 제안한다. 실험 결과, 제안 방법인 'Modified ECCD' 기법이 ${\chi}^2$ 및 ECCD 기법에 비해 높은 분류 성능을 보였으며, '문서별 범주 가중치' 특징 변수를 'Modified ECCD' 기법으로 선택된 자질어 변수에 추가하여 학습하였을 경우에 더 높은 분류 성능을 보였다. Web information service needs a document classification system for efficient management and conveniently searches. Existing document classification systems have a problem of low accuracy in classification, if a few number of feature words is selected in documents or if the number of documents that belong to a specific category is excessively large. To solve this problem, we propose a document classification system using 'Modified ECCD' feature selection method and 'Category Weight for each Document'. Experimental results show that the 'Modified ECCD' feature selection method has higher accuracy in classification than ${\chi}^2$ and the ECCD method. Moreover, combining the 'Category Weight for each Document' feature value and 'Modified ECCD' feature selection method results better accuracy in classification.

Burns in children result in the loss of precious life, or if the child survives, in much suffering from physical, emotional, social, and economic problems. These burn accidents to children happen in the bustle of family life and frequently without any warning. With this background information, this study was designed to identity types of burns in children and mothers' attitudes towards, and knowledge of burn prevention, in order, to not only, in still a safety consciousness regarding the seriousness of burn accidents and the strengthening prevention, but also as basic data towards the development of an educational program aimed at prevention. From May 1 to May 25 in 1997, data were collected from the mothers of children attending five day care centers and kindergartens located in Seoul, which had been selected for the study. The tools used for the study, which were developed by the researchers, surveyed the type of burns suffered by children, mothers' knowledge of burns and attitudes toward burn accidents. The data were analyzed through real numbers percentages and analysis was done using SPSS computer programs. The results of the study show that the most frequent type of burn accidents were those caused by hot water(55.4%) and these were frequently related to everyday habits that easily lead to danger. Further, the first aid treatment following a burn was weak. The majority of the mothers had not instructed their children on who to contact in the case of a fire, first aid for burns, or how to take escape in the case of a fire. This left the children in a defenseless position in case of a fire. The mothers showed a lack knowledge, on what to do when a blaze is discovered, how to put out a fire, first aid for burns, escaping from a fire and appropriate water temperature, in that 50% of the time they answered incorrectly. From this study a prevention program, HIPP (Home Injury Prevention Program) could be developed that includes fire prevention habits and first aid for burns. This program can be used with kindergarten and elementary school children for group education on fire prevention and can be used as a foundation for construction of a system of facilities and equipment to prevent fires and also prevent injury from fires.

This study was done in order to identify symptoms of grief and patterns of coping in mothers of chronically ill children. Nurses, as health professionals, must understand helpful coping methods for mothers who have chronically ill children. Based on this knowledge, nurses can develop appropriate nursing intervention strategies, and so help the mothers to develop effective ways of coping and give support to mothers with chronically ill children in process of coping with this grief. The research questions guiding this research were: 1. what type of grief does the mother have at the time of child's diagnosis and at present\ulcorner 2. what are the problems confronting the mother 3. what are the coping patterns of the mother\ulcorner 4. is there a difference according to child's diagnosis in the mother's grief and coping pattern\ulcorner The subject for this study were obtained by taking a convenience sample of 120 mothers with a chronically ill child. Interviews took place in four medical school hospitals and one medical center in Seoul from March 19th to May 16th 1990. The tools used in this study were Mcfarlan's(1983), Grief contents, Folkman & Lazarus(1983), Ways of Coping and Hymovich's (1983) the Chronicity Impact and Coping Instrument. The findings were as follows; 1. Grief items had a maximum score of three points. The highest item scrores at the time of diagnosis, were in order, heart broken, talkative, and could not do anything, at the present, 'talkative', 'heart broken' and 'busy myself with other things'. 2. The problems confronting the mothers were 'worry about ill child's future', 'her responsibilities in taking care of the ill child.' 3. Most of the mothers used similar ways of coping, that is 'problem focused coping', 'detachment', 'wishful thinking', 'seeking social support" and 'focusing on the positive and hardly any of them used 'tension reduction'. 4. There was a sinificant difference in coping methods according to the childs diagnosis, leukemia, cancer hemophillia and nephrotic syndrome. The most frequently used coping method was detachment, especially for the mother of the child with. 5. At the time of diagnosis there was a positive correlation between the level of grief and the coping method of detachment and seeking social support.

Objectives : The aim of this work was to study the anorexigenic effect of Taeyuemjowui-tang(Taiyintiaowei-tang) in obese Zucker rat, assessing the mRNA of NPY and POMC in hypothalamus. Methods : Obese Zucker (fa/fa) rats were administered Taeyeumjowui-tang(Taiyintiaowei-tang) (300 mg/kg p.o.) daily for 6 weeks. The control group was administered sterile water. The weight of the whole body, food consumption, NPY and POMC expression, plasma levels of glucose;total cholesterol;triglyceride;free fatty acid, and size of the epididymal fat cells were measured. Statistical comparisons among the normal, control and sample group were done by ANOVA test. Results : Taeyuemjowui-tang(Taiyintiaowei-tang) administration in obese Zucker rats generated a reduction in food intake, triglyceride and free fatty acid. A significant decrease in NPY expression was observed. Conclusions : These results suggest that Taeyuemjowui-tang(Taiyintiaowei-tang) could be effective for the treatment of obesity as an anorexigenic agent.

본 연구는 현재 대전광역시에서 일어나고 있는 수돗물 민영화 갈등쟁점을 정책논변모형에 따라 재구성 하였다. 실증분석을 통해 다음과 같은 시사점을 제시한다. 첫째, 정책주장에서 전제 되어야 정책관련정보에 오류가 있다면, 이상적 담화를 이끌어 갈 수 없다. 사전에 정책주장의 정당성을 확보하기 위해 관련정보의 충분한 분석이 필요하다. 둘째, 민영화논란이 시작된 시점에서는 대부분 반대의견을 듣고 그에 대한 문제점을 지적했으나 시간 지나면서 희석 화 돼는 경향을 보여주고 있다. 일방적인 자기주장에 빠져 왜곡된 담화를 이끌어 가게될 경우 상대 주장에 흡수되어 무력화 될 수 있다. 셋째, 정책결정과정에서 서로 다른 이해관계자들은 자기집단에 유리한 대안을 선택하기 위해 정책결정에 오류를 범할 수 있다. 장기적인 시각에서 당장 눈앞의 이익보다는 불확실한 미래를 위해 절제하려는 보편적인 가치에 더 많은 관심을 가져야 할 것이다. This study is the privatization of water conflicts currently taking place in Daejeon, issues were reconstructed according to the policy argument model. Through empirical analysis suggests the following implications. First, the premise must be claimed in the policy if there is an error in the policy-relevant information and can not lead an ideal discourse. A sufficient analysis of the relevant information needed to ensure the validity of the policy claimed in advance. Second, at the time the controversial privatization began listening to opposing views, but most of the problems pointed out for it shows a tendency dwaeneun diluted over time. If all that unilateral assertiveness to go led to a distorted discourse it can be absorbed to neutralize the opponent claims. Third, the different stakeholders in the decision-making process may commit errors in decision making to select a favorable alternative to his group. In the long-term perspective it will have more attention to the universal values that you want to temperance to an uncertain future, rather than the interests of right front.

가솔린 GDI 인젝터 미동작 실시간 판단과 인젝터 전류 변경을 통한 실화 개선로직

Recently, vehicles equipped with a GDI injector began to use a lot of high-pressure areas. As a result, the number of injector malfunctions in the field increased significantly compared to the past. Since the ECU detects a misfire through the abnormal lambda value and RPM fluctuations, it is impossible to know whether it is caused by a specific H/W problem. So if a misfire occurs due to poor performance of the GDI injector, the ECU cannot determine the exact cause and mis-maintenance may occur. A vehicle equipped with a GDI injector performs injector closure detection for precise flow control, and a mechanical malfunction of the injector can be determined using the injector close detection value. In this paper, the ECU detects the non-operation of the GDI injector in real-time, and at this time, we propose a logic that differentiates the injector driving current waveform to enable the injector to operate.

Objectives : It is recently reported that Myofascia Pain Syndrome(MPS) is a major cause of musculoskeletal pain. Abnormal spinal curvature, such as hyperlordosis, scoliosis, is the most important perpetuating factor of MPS but its pathology is complicated with variable interpretation. We reviewed on the definition, incidence, classification and clinical correlation of the abnormal spinal curvature. Methods : We referred to internet libraries providing full texts of medical articles and studied the medical documents about abnormal spinal curve. Results and conclusions : Posture is build up with dynamic reaction of gravity and individual strength. Abnormal spinal curvature is the result of postural compensation disorder caused by muscular imbalance, personal habit, mental condition, shape of body, leg length insufficiency, inadequate motions in babyhood. Classifications of sagittal plane disorder are Upper/Lower Crossed Syndrome, Kendall`s classification. Coronal plane classifications are handedness patterns, 4 body type of GCM, fascial compensation patterns. Correlation between abnormal spinal curvature and pain syndrome is denied by several clinical studies. It is suggested that more comprehensive interpretation method, such as fascial network, Sa-Sang(四象) constitution.
