The purpose of this study is to find out influential variables related to Home Management Ability of urban home makers. This study focuses on the following aspects; 1) to find out which variables of sociodemographic variables (ie. home maker's age, level of education-husband, wife, job-husband, wife, income, duration of marriage), of psychological variables (ie. degree of resourcefulness recognition, degree of stress recognition, degree of life level recognition) have significant effects on home management ability. 2) to find out which variables of sociodemographic variables have significant effects on degree of resourcefulness recognition, of stress recognition, and of life level recognition. 3) to identify the influence of significant variables related to home management ability. Data was analyzed by frequency. percentage, mean , F-test, t-test, Duncan's multiple range test. regression analysis , path analysis pearson's r. x2-test. Major findings are as follows; 1) The level of education (husband , wife)and occupation of husband were variables to have influences on home management ability. 2) a. The level of education (husband, wife) and income were variable to have influences on degree of resourcefulness recognition. b. The employment of home makers. income, and the form of family were variables to have influences on degree of stress recognition. c. The level of education (husband, wife) occupation of husband , income , and duration of marriage were variables to have influences on degree of life level recognition. 3) There were significant relationships between home management ability and degree of resourcefulness recognition and of stress recognition (r=0.13, r=-0.12, p<.05). a. The higher degree of resourcefulness recognition, the higher home management ability (x2=11.17. df=4. p<.05) b. The higher degree of stress recognition, the lower home n=management ability (x2=14.64. df=4. p<.01) 4) The education level of homemakers (β =0.15) and income (β=0.12) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β =0.13) 5) The employment of home makers (β=-0.17) was a variable to have indirect influence on home management ability through the medium of the degree of stress recognition(β=-0.12) 6) the education level of husband (β=0.16) and income (β=0.32) were variables to have direct influence on degree of life level recognition. 7) The degree of life level recognition (β=0.13) and education level of home makers (β=0.17) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β=0.13) 8)The degree of life level recognition (β=-0.22) the employment of home makers(β=-0.17) and the from of family(β=-0.10) were variables to have indirect influences on home management ability through the medium of the degree of stress recognition.

This study aims to survey the satisfaction level with the fit of ready-made suits(jackets and pants) among adult males and thereby to show its differences by the age group and body type. The respondents to the questionnaire survey were 465 males, aged 20 through 59 years. The conclusions are as follows: 1. The average satisfaction level for the fit of each item ranged from 2.65 to 3.57, with the higher level found in jackets than in pants, and also in circumference parts than in length parts 2. The satisfaction level for the fit by the age of adult males showed inter-group differences in the parts of jacket length, sleeve length, shoulder width, sleeve openings, and sleeve band width for jackets; and pant length of pants. 3. The satisfaction level for the fit by the body type of adult males indicated into-group differences in chest circumference of jackets only. 4. The satisfaction level for the fit, with the exclusion of the age and body type relationship showed that adult males are affected more by the age than by the body type. 5. In the repair frequency by the item, pants(45.6%) showed a higher level than jackets(24.7%). The parts with a high repair level by the item were jacket length(8.4%) and steeve length(19.8%) for jackets; and pant length(42.4%) and waist circumference(8.4%) for pants.

Two-level 형태소 분석 방법은 규칙 기반 방법 중 하나로 형태소의 변화 현상을 규칙으로 처리하고, 기본 어휘 사전을 기반으로 형태소 결합관계를 분석한다. 이는 언어에 독립적인 방법으로 한국어에 대해서도 일부 구축되어 적용됨이 증명되었다. 그러나 기존 한국어에 대한 Two-level 형태소 분석기는 사전을 수동으로 구축하여 규모가 매우 작고 실제 사용에 제한적이었으며, 과분석이 많아 효율성이 매우 떨어졌다. 본 논문은 세종 품사부착 말뭉치에서 대규모의 Two-level 어휘 사전을 자동으로 구축하여 형태소 분석기의 적용 범위를 넓히고, 형태소간의 결합관계를 어휘 정보와 어휘 형태에 따른 하위품사 정보를 이용하여 분석함으로써 형태소 분석기의 성능을 향상시킬 수 있는 방법을 제시한다. 실험 결과, 기존의 방법보다 형태소 분석기의 과분석을 68% 이상 줄여 f-measure를 25.5% point 이상 향상시킬 수 있었다.

The purpose of this study was to find out the 119 rescue and first aid's satisfaction level for their occupations, understand the influential factors of the satisfaction level and also analyze the level of each working districts. Therefore to provide basic information of policy decisions to increase the satisfaction level. Date were collected from 400 national the 119 rescue and first aids by questionnaire and using the tools, which has developed by Slavitt, from August 2 to September 30, 2002. The data were analyzed by percentage, mean t-test and ANOVA. Divided 39 items into 7 provinces to find out the satisfaction level of each province, follow as the influential factors of the satisfaction level. 1. The most of the 119 rescue and first aids were satisfying about their occupations as they got 3.02 marks out of 5, which is the full mark. 2. As the results after analyzed the relation ship between the satisfaction level and the general characteristics of analyzed the relation ship between the satisfaction level and the general characteristics of the 119 rescue and first aids, there were not statistically significant differences of sex distinction, age, scholarship, not married and has or have married, grade and qualification. There were statistically significant differences follow as working period, applying motive, moving, seeking a job, working place, an adviser, work overtime and compensation follow as work overtime. 3. It appeared that all the 119 rescue and first aids were satisfying enough about duty itself but were dissatisfying about working condition. As the results; job itself got 4.00, reciprocal action got 3.74, business demand got 3.28, autonomy got 3.06, organization demand got 2.96, pay got 2.43 and working condition got 1.72, each out of 5 full marks. As you see the results, most of the 119 rescue and first aids are satisfying about a job itself but they are dissatisfying about their working condition. Therefore we should formulate a plan that can increase the satisfaction level by improving duty system for 24 working hours per week.

여러 가지 장점으로 인해 Ni-Ti 전동 파일을 근관성형에 사용하는 빈도가 점차 증가되는 추세이지만, 초심자를 대상으로 한 연구는 부족한 실정이다. 이에 본 연구에서는 초심자에서 Ni-Ti 전동 파일을 사용할 때 근관 형성의 효용성을 평가하고, 어떤 방법이 초심자에게 적절한지를 알아보고자 하였다. 근관형태가 재현된 레진 블록을 이용하여 12명의 초심자와 4명의 숙련자가 근관 형성을 시행하였다. 각 술자는 ProFile, ProTaper, Hybrid (ProFile＋ProTaper)를 이용하여 각각의 레진 블록을 세 개씩 근관형성하고, 각 파일 별의 근관 형성 시간을 기록하였다. 근관 형성 전과 후의 digital 이미지를 중첩하여 치근단으로부터 1, 2, 3, 4, 5, 6, 7mm level에서 근관단면의 총길이 변화량, 만곡 외측의 길이 변화량, 만곡 내측의 길이 변화량, 중심이동량, 중심이동율과 치근단에서의 apical transportation을 구하고, 초심자와 숙련자 사이의 차이를 비교 평가하였다. 실험결과 ProFile군의 1, 3, 5, 6, 7mm level과 ProTaper군의 6mm level, Hybrid군의 3mm level에서 초심자의 근관단면의 총길이 변화량이 숙련자보다 많았다. 모든 군에서 치근단으로부터 4, 5, 6, 7mm level에서는 근관 중심이 만곡내측으로 이동하였고, 1 2, 3mm level 에서는 만곡외측으로 이동하였으나, 숙련자가 시행한 Hybrid군의 3mm level과 비숙련자가 시행한 ProTaper 군의 3mm level에서는 만곡내측으로 이동하였다. 모든 군의 3mm level과 ProFile 군의 5mm level에서 초심자의 중심이동율이 숙련자에 비해 컸으며, 초심자가 ProTaper를 사용시 더 큰 apical trans portation을 보였고, 모든 군에서 초심자가 근관형성시 더 많은 시간이 걸렸다. ProFile과 ProTaper를 이용한 Hybrid technique이 초심자에게 추천되며, 초심자들도 충분히 교육받는다면 만곡된 근관의 근관형성에 있어서 Ni-Ti rotary file의 이용이 가능하리라고 사료된다.

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.
