The purpose of this study is to investigate 1) the level of the city housewives' sense and behavior of wedding and ancestral service according to the background variables, 2) the relationship of the sense of wedding and ancestral service and behavior, and 3) what the most influential factors are. For the purpose of this study, 700 questionnaire were distributed to the housewives who live in Seoul and collected during the February 1989. And the measuring instruments are composed of 9 questions, 11 questions of the sense of wedding service, 12 questions of the sense of ancestral service, 11 questions of the behavior of wedding service, and 12 questions of the behavior of ancestral service. To obtain the sense and behavior of wedding and ancestral service scale, item analysis through Pearon's correlation and factor analysis, frequency distribution, percentile, mean, standard deviation, t-test, F-test, Pearson's γ, Paired-t-test, Duncan's Multiple Range Test, and Stepwise multiple Regression were used for data analysis. The major fidnigs are as follows: 1. The general tendency of the city housewives' sense of wedding service was modern. That of the city housewives' sense of ancestral service was the mid level of the traditional and the modern. According to background variable (ie: age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' sense of wedding service is different significantly. Accoring to background variable(ie: age, educational level, the average home income a month, the number of children, the duration of marriage, religion, the existence of married son and daughter), the city housewives' sense of ancestral service is different significantly. 2. The general tendency of the city housewives' behavior of wedding service was modern. That of the city housewives' behavior of ancestral service was somewhat modern. According to background variable(ie: age, educational level, the number of children, the duration of marriage, the existence of married son and daughter, the form of family), the city housewives' behavior of wedding service is different significantly. According to background variable(ie" age, educational level, the number of children, the duration of marriage, religion, the existence of job, the existence of married son and daughter), the city housewives' behavior of ancestral service is different significantly. 3. There were positive correlation between the city housewive' sense and behavior of wedding and ancestral service(P<.001). And the housewives' sense of wedding service was modernized than that of ancestral service, the housewives' behavior of ancestral service was modernized than that of wedding service. 4. The city housewives' sense of wedding service was the duration of marriage(β=-.226), influential factor. And influential factors on that of ancestral service were educational level(β=.250), the existence of married son and daughter(β=-.123), number of children(β=-.101). The influential factors on the city housewives' behavior of wedding service were age(β=-.193), the form of family(β=.097). And that of ancestral service were educational level(β=165), the number of children(β=-.157).

본 연구에서는 1998년부터 2002년 동안 주식분할을 실시한 과거 거래소 상장기업을 대상으로 장기성과를 분석하였다. 장기성과는 Event-time 포트폴리오 접근방식으로 측정되어지는 BHAR과 CAAR을 이용하였고 또한 Calendar-time 포트폴리오 접근방식으로 1요인 CAPM 모형과 3요인 모형을 이용하였다. 분석결과 주식분할의 공시월 부근에서 유의적인 양(+)의 초과수익률을 발견할 수 있었다. 이러한 결과는 기존 국내 연구들에서 밝혀진 바와 같이 주식분할의 공시효과가 존재한다는 것을 재확인 한 것이다. 하지만 이후 기간별 BHAR과 CAAR 모두 유의적인 음(-)의 초과수익률이 나타났으며, 이러한 결과는 Calendar-time 포트폴리오 접근방식인 1요인 CAPM 모형과 3요인 모형에서도 재확인 할 수 있었다. 분할비율에 따른 BHAR과 CAAR을 분석한 결과 분할비율이 높은 기업군도 주식분할 이후 여전히 음(-)의 초과수익률이 나타났으며 주식분할 이전 보다 이후에 영업성과가 더 악화되는 것으로 나타났다. 따라서 주식분할이 기업의 수익성이 개선된다는 신호로 보기에는 무리가 있었다. 배당성향의 증감에 따라 표본을 분류하여 장기성과를 분석한 결과에서 두 표본 간에 뚜렷한 차이를 발견할 수 없었다. 본 연구의 결과를 통하여 볼 때 주식분할은 한국 주식시장에서 단기적으로는 주가에 양(+)의 영향을 미치고 있지만 장기적으로는 주식분할이 주가에 미치는 영향은 없는 것으로 판단된다.

The purpose of this study was to investigate the status of children's breakfast skipping and their mothers' needs for breakfast service at child care centers. A survey was conducted with mothers of children aged 3 to 5 years and attending child care centers in Gwanak-gu, Seoul. Out of 960 questionnaires distributed to the caregivers at 32 child care centers, 633 were returned (66% response rate), and 449 were analyzed (47% analysis rate) after excluding data from the respondents not meeting the selection criteria for this study: mothers of children aged 3 to 5 years. Over 2/3 (69%) of children ate breakfast every weekday (Breakfast Eaters) and almost 1/3 (31%) of children skipped breakfast one time or more often on weekdays (Breakfast Skippers). The collected data were compared between Breakfast Eaters and Breakfast Skippers. The average Good Dietary Practice Score of Breakfast Skippers was significantly lower than that of Breakfast Eaters, implying poorer dietary habits. A higher percentage of mothers of Breakfast Skippers (62%) responded that breakfast service was 'necessary' or 'very necessary' at child care centers than those of Breakfast Eaters (27%). A multiple logistic regression analysis was conducted to determine factors affecting mothers' needs for breakfast service at child care centers. The result showed that the children's ages, mothers' occupational status, household monthly income, frequencies of eating breakfast on weekdays and satisfaction level with morning snack provided at child care centers affected mothers' needs for breakfast service at child care centers. In particular, mothers who had a full-time job (OR = 2.06) than housewives, mothers whose children did not eat breakfast at al (OR = 3.54), ate $1{\sim}2$ times (OR = 5.50) or ate $3{\sim}4$ times (OR = 3.80) on weekdays than those whose children ate breakfast every weekday were more likely to have needs for breakfast service at child care centers than housewives. In conclusion, Breakfast Skippers tended to have poorer dietary habits than Breakfast Eaters and Full-time working mothers had higher needs for breakfast service at child care centers. This study results suggest that child care centers consider serving breakfast to children as the number of working mothers increases.

최근 국내에 상업적으로 유통되고 있는 '만풍배' 배(Pyrus pyrifolia L.)나무 1년생을 재식(2001년)하여 정식 8년차까지 4가지 수형(Y자형, Y-II형, 평덕형, 평덕배상형)을 적용하여 남부지방에 적합한 수형을 제시하고자 본 시험을 수행하였다. Y자형과 평덕형은 수관점유율이 높게 형성되었고 8년차에는 70-80%의 점유율을 보였다. 8년간 주당 누적수량은 소식이면서 주지가 다른 수형보다 1개 더 많은 평덕배상형에서 가장 높았다. 재식 5년차와 8년차의 누적 수량이용효율은 Y-II형과 평덕형에서 높게 나타났다. 8년간 ha당 누적수량은 Y자형과 평덕형이 각각 103톤과 101톤으로 Y-II형과 평덕배상형보다 2배 가까이 높았다. 재식 8년차에 평덕형은 평균과중과 과육당도를 증가시켰고 순소득도 가장 높았다. Y자형과 평덕배상형은 전정량 증가에 의한 노동량 및 시간이 증가하여 생산성이 낮은 수형으로 평가되었다.

This study was conducted to evaluate the effects of energy level of concentrate feed in finishing Hanwoo steers for 6 months before slaughter. Feeding trial was done with 2 treatment groups, IDN72 (72% of TDN in concentrate) and TDN74 (74 % of TDN in concentrate). The body weight (from 19 to 24 months) tended to be higher in TDN74 than in TDN72, but was not significant. Average daily gain of TDN74 was higher by 4.4 % in comparison to TDN72. There was no significant differences in concentrate, dry matter and TDN intake per I kg body weight gain between TDN72 and TDN74. And there was a tendency to improve crude protein intake per I kg body weight gain by increasing TDN content from 72 to 74 %. The dressing percentage tended to be higher in TDN74 than in TDN72, but was not significant. Salable meat percentage tended to be lower in TDN74 than in TDN72 because of higher body fat percentage in TDN74 than in TDN72. There were no significant differences in marbling score, meat color, fat color, carcass weight, rib-eye area and back fat thickness between TDN72 and TDN74. Significant differences were not found in shear value, cooking loss, water holding capacity or moisture and protein contents of longissimus dorsi (LD) muscles between TDN72 and TDN74. Fat content of LD muscles tend to be lower in TDN74 than in IDN72 but without any significance. There was a tendency to improve juiciness and taste by feeding IDN74 rather than TDN72. Especially, tenderness of TDN74 was increased by 7.4% in comparison to TDN72 (p < 0.05). Gross income from TDN74 was higher than TDN72 by 5% The results suggested that significant differences were not found in growth performance, feed conversion and carcass characteristics between TDN72 and TDN74. The results also show that more studies are required to clarify the energy level for finishing Hanwoo steers.

산업의 발달과 소득의 증가로 인해 목재와 같은 다공성 물질의 수요 및 생산은 지속적으로 증가하고 있다. 축산 농가를 비롯한 가공 산업 분야에서 목분의 활용이 증대됨에 따라 화재 위험도 높아지고 있다. 화재 발생시 목분은 깊이 방향으로 연소의 전이가 발생하며 내부 산화제의 소멸에 따라 화염이 없는 훈소로 진행되기도 한다. 훈소로 진행되는 경우는 화원의 위치 파악 곤란으로 초동진화에 실패하여 2차 피해를 키우는 직접적 원인으로 작용한다. 본 연구에서는 국 내외적으로 수요가 높은 뉴질랜드산 목분을 대상으로 자연대류 상태의 하향식 심부화재를 모사하였다. 본 실험에서는 실험용기 내의 목분의 체적 밀도(3%, 5%, 10%, 15%)를 변화시켜 깊이방향으로 전파되는 심부의 온도를 측정하여, 화원의 전이 속도를 실험적으로 규명하였다. 본 실험의 결과로 목분의 체적 밀도가 증가함에 따라 내부 온도는 감소하는 경향을 확인하였다. 그러나 목분 밀도체적 $0.2140g/cm^3$ (5%) 이상의 조건에서는 온도의 감소가 발생하지 않음을 실험적으로 규명하였으며 본 실험을 통하여 뉴질랜드산 소나무 목분의 온도 전이속도는 평균 0.249 mm/min의 속도 값을 가짐을 밝혔다.

This study was carried out to find out major factors to mitigate carbon emission using Life Cycle Assessment (LCA). System boundary of LCA was confined from sowing to packaging during vegetable production. Input amount of agri-materials was calculated on 2007 Income reference of white radish, chinese cabbage and chive produced at open field and film house published by Rural Development Administration. Domestic data and Ecoinvent data were used for emission factors of each agri-material based on the 1996 IPCC guideline. Carbon footprint of white radish was 0.19 kg $CO_2kg^{-1}$ at open fields, 0.133 kg $CO_2kg^{-1}$ at film house, that of chinese cabbage was 0.22 kg $CO_2kg^{-1}$ at open fields, 0.19 kg $CO_2kg^{-1}$ at film house, and that of chive was 0.66 kg $CO_2kg^{-1}$ at open fields and 1.04 kg $CO_2kg^{-1}$ at film house. The high carbon footprint of chive was related to lower vegetable production and higher fuel usage as compared to white radish and Chinese cabbage. The mean proportion of carbon emission was 35.7% during the manufacturing byproduct fertilizer; white radish at open fields was 50.6%, white radish at film house 13.1%, Chinese cabbage at outdoor 38.4%, Chinese cabbage at film house 34.0%, chive at outdoor 50.6%, and chive at film house 36.0%. Carbon emission, on average, for the step of manufacturing and combustion accounted for 16.1% of the total emission; white radish at open fields was 4.3%, white radish at film house 15.6%, Chinese cabbage at open fields 6.9%, Chinese cabbage at film house 19.0%, chive at open fields 12.5%, and chive at film house 29.1%. On the while, mean proportion of carbon footprint for the step of $N_2O$ emission was 29.2%; white radish at open fields was 39.2%, white radish at film house 41.9%, Chinese cabbage at open fields 34.4%, Chinese cabbage at film house 23.1%, chive at open fields 28.8%, and chive at film house 17.1%. Fertilizer was the primary factor and fuel was the secondary factor for carbon emission among the vegetables of this study. It was suggested to use Heug-To-Ram web-service system, http://soil.rda.go.kr, for the scientific fertilization based on soil testing, and for increase of energy efficiency to produce low carbon vegetable.

Purpose: This study was conducted to explore the relationship among health belief. health locus of control and patients sick-role behavior compliance of diabetic mellitus patients visiting public health center. Method: The subjects of this study were 193 of the diabetic patients who were visiting 4 Public Health Center in B city. The instrument used for measuring health belief was Park's(1985). for health locus of control was Wallston. et al's(1978) and for sick-role behavior compliance was Park's(1984). The data were collected with structured questionnaires; total 58 items contained about health belief. health locus of control and sick-role behavior compliance from 1st to 31st July. 2001. The data was analyzed by the SPSS/PC programs using t-test. Pearson's correlation coefficient. ANOVA and Scheffe-test. Result: The average score of the health belief was $57.99\pm9.45$ health locus of control was $66.83\pm9.48$ and sick-role behavior compliance was $42.81\pm7.00$. Statistically significant factors influencing the health belief among social demographic characteristics were family number(F=3.818. p=0.024), monthly income(F=5.153, p=0.002), time of diagnosis(F=3.937. p=0.002) and difficult to control disease(F=5.803. p=0.000). The significant factors influencing the health locus of control were marital status(F=4.669. p=0.010). Also significant factors influencing the sick-role behavior compliance were monthly incomes(F=5.245, p=0.000). the time of diagnosis(F=4.424. p=0.001) and admission to hospital with diabetes(F=9.031. p=0.000). There was negative mild correlation comparatively between health belief and sickrole behavior compliance(r=-0.142, p<0.05) but no correlation in sensitiveness/severity, barrier, benefit(p<0.05). There was no correlation between internal. external. chance health locus of control and sick-role behavior compliance (P>0.05). Conclusion: There was a negative weak relationship between health locus of control and patient's sick role behavior compliance. Therefore further study to investigate the relating factor of the sick role behavior compliance among above of middle aged diabetes mellitus patients is necessary.
