This study examines the effects of health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture and provides data for enhancing the quality of their lives. The sample included 218 consenting subjects who understood the purpose of the study. These subjects resided in three cities in Jeollanam-do, Korea, and were grandmothers entrusted by their adult children with a considerable amount of nurturing for their preschool-aged grandchildren under the age of six. First, the subjects scored an average of 3.05 for health-promoting behaviors and 2.42 for entrapment. Second, the entrapment measurement based on general characteristics showed a higher level of entrapment for those with better health, a lower education level, no religion, male grandchildren to nurture, and unsatisfactory compensation. Third, health-promoting behaviors and entrapment (r=-.304) were negatively correlated. Fourth, the analysis results for effects of health-promoting behaviors of grandmothers on entrapment based on general characteristics of grandmothers as a control variable reveal a significant effect of health-promoting behaviors on entrapment. In other words, the greater the employment of health-promoting behaviors, the less likely the entrapment was to be perceived. Fifth, the results for effects of subcriteria for health-promoting behaviors on entrapment reveal a decrease in entrapment when the subjects engaged in an appropriate level of physical activity with a relaxed state of mind. These results suggest that health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture are likely to influence entrapment and thus that grandmothers should make efforts to actively engage in health-promoting behaviors to reduce any maladaptive effects on nurturing. Social support and related programs should be fostered to enable grandmothers to better practice health-promoting behaviors while nurturing their grandchildren.

The organ or tissue doses were determined with head and neck phantom measurement for multiple axial scans (36 slices), multiple coronal scans (13 slices), 3 types of single axial scans(orbit, maxillary sinus and mandibular canal) and single coronal scan (maxillary sinus). For each scan sequence 30 TLDs were placed in selected sites(16 internal sites and 14 external sites) in a tissue-equivalent phantom. The exposure was made at 120kVp, 500mAs with 5 mm slice width. The results were as follows : 1. In multiple axial scans, the greatest effective dose recorded was that delivered to the thyroid glands(2.77 mSv) and the least was that received by the skin(0.05 mSv). From these data, stochastic effects were 202.2x10/sup -6/ and 3.7×10/sup -6/, respectively. 2. In multiple coronal scans, the greatest effective dose recorded was that delivered to the salivary glands(0.58 mSv) and the least was that received by the skin(0.01 mSv). From these data, stochastic effects were 42.2×10/sup -6/ and 0.7×10/sup -6/, repectively. 3. Among single axial scans, the greatest effective dose recorded was that delivered to the salivary gland(0.38 mSv) in maxillary sinus scan. From this data, stochastic effect was 27.7×10/sup -6/. 4. In single coronal scan, the greatest effective dose recorded was that delivered to the salivary gland(0.01 mSv). From this data, stochastic effect was 1.0×10/sup -6/. 5. The equivalent dose measured that delivered to the lens of the eyes was 69.64 mSv in multiple axial scan, 39.32 mSv in multiple coronal scan and 36.77 mSv in single axial scan(orbit).

Ti과 Si의 초기 반응이 Titanium Silicide의 표면 거칠기 (Surface roughness)를 고찰하기 위해 연구하였다. 형성기구는 In-situ AES와 LEED의 측정장비로 연구하였다. Ti의 하나나 두 원자층이 초고진공에서 원자적으로 깨끗한 Si 기판 위에 증착되었다. Reconstruction이 된 $7{\times}7$ Si(111) 표면이 초 고진공하에서 얻어졌으며 박막의 증착은 Quartz Crystal Oscillator로 측정되었다. In-situ 측정 결과 Ti과 Si의 초기 반응이 실온에서 일어났으며 Disorder막을 형성하였다. 낮은 온도($200^{\circ}C{\sim}300^{\circ}C$)에서 Ti과 Si의 Intermixing이 고찰되었고 $400^{\circ}C$ 근처에서 $1{\times}1$ Si(111) LEED 패턴이 관찰되었다. 이것은 Disorder막이 Order막으로 변화가 생긴 것을 나타낸다. 더 높은 온도에서 $7{\times}7$ Si(111) LEED 패턴이 재관찰되었는데 이것은 3차원적인 $TiSi_2$의 형성을 증명하는 것이다.

To establish a prediction table of parturition day real-time B-mode ultrasonographic examinations were performed in 12 pregnant Shih-tzu bitches. Measurement of inner chorionic cavity diameter and fetal head diameter was performed from 15 days of gestation to parturition. These were converted retrospectively based on the day of parturition (Day 0). The data of inner chorionic cavity diameter obtained from Day -44 to Day -25 and fetal head diameter obtained from Day -25 to Day -1 were used to compile a prediction table of parturition day. The 22 pregnant Shih-tzu with unknown mating time were examined to assess an accuracy of the table established in this study. And these results were applied to the prediction of parturition day and compared to actual parturition day. Parturition day prediction based on the inner chorionic cavity diameter and fetal head diameter was 100% accurate within ${\pm}2$ days. In addition, the accuracy for parturition day within 0, ${\pm}1$, and ${\pm}2$ days interval using the prediction table of parturition day were 68, 82, and 100%, respectively. Therefore, the prediction table of parturition day seems to be a useful tool for the prediction of parturition day in practice.

This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health questionnaire(GHQ-60) as a instrument of stress measurement. The number of subjects were 445 residents who lived in three areas(large city, middle city, and rural area) and they were individually interviewed in March, 1994. The results of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age, sex variables: (a) the residents in middle city among three areas had the highest level of stress; (b) the residents who were more than 60 in age had the highest level of stress: (c) the female residents had more stress than male residents, (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age, sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents' age.

In the last several years, studies on the association of oxidative stress damage with exposure in the work place have been conducted. Xenobiotics create an imbalance of the homeostasis between oxidant molecules and antioxidant defense. By monitoring oxidative stress biomarkers, information was obtained on damages induced by oxidative stress and the toxicity of xenobiotics. In the present study, a Job Exposure Matrix (JEM) was constructed using the data from the Working Environment Measurement (WEM) of painters in the shipyard industry from the past 3 years to assess the exposure status. Additionally, by measuring the concentration of urinary malondialdehyde (MDA), the effect of lipid peroxidation was examined. The subjects consisted of 68 workers who were exposed to mixed organic solvents in the painting process and 25 non-exposure controls. The exposure indices of the exposure groups were significantly different (sprayer: 0.83, touchup: 0.54, assistant: 0.13, P<0.05). The urinary MDA concentration of the exposure group was 48.60${\pm}$ 39.23 ${\mu}mol$/mol creatinine, which was significantly higher than 18.03${\pm}$16.33 ${\mu}mol$/mol creatinine of the control group (P<0.05). From the multiple regression analysis of urinary MDA, the regression coefficient for exposure grade was statistically significant. In future studies, evaluation of the antioxidant levels of subjects should be performed simultaneously with quantitative exposure measurements.

This study investigated the physicochemical and sensory characteristics of yanggaeng prepared with various amounts of Opuntia ficus-indica var. saboten powder (as ratios of 1%, 3%, 5%, 7% to the total materials). According to the results, the pH of yanggaeng decreased significantly with the addition of Opuntia ficus-indica var. saboten powder (p<0.001). Increasing the amount of Opuntia ficus-indica var. saboten powder in the yanggaeng tended to increased $^{\circ}Brix$ value (p<0.01). For color values, lightness (L) values were reduced by increasing the amount of Opuntia ficus-indica var. saboten powder, redness (a) and yellowness (b) while values were increased significantly (p<0.001). Texture measurement scores in terms of hardness, springness, and Adhesiveness for yanggaeng showed that sample groups were lower than those of the control group. Cohesivene and chewiness were higher in the additive group than in the control group. Antioxidant activities, evaluated by DPPH radical scavenging capacity, Nitrites cavenging activity, and total phenolic substances content increased when increased the amount of Opuntia ficus-indica var. saboten powder (p<0.001). Results of descriptive analysis showed that by increasing the amount of Opuntia ficus-indica var. saboten powder, some attributes such as the intensity of the color, sweet, hardness and chewiness increased (p<0.01). It concluded that yanggaeng containing Opuntia ficus-indica var. saboten can be prepared with good sensory properties and antioxidant activities, and the addition of 3% Opuntia ficus-indica var. saboten powder was found to be ideal. Sensory evaluation scores in terms of color, odor, taste, texture, and overall preference of groups with 3% of Opuntia ficus-indica var. saboten powder did not show any significant differences when compared to the control group. Based on the above results, this study suggests that the addition of 3% Opuntia ficus-indica var. saboten powder may be the best substitution ratio for yanggaeng.

본 논문에서는 Y자 형태의 급전 구조를 사용한 두 개의 편파 변환 재구성 패치 안테나를 제안하였다. 제안된 안테나는 정사각형 형태의 패치, Y자 형태의 급전 구조, 하나의 핀 다이오드, 다이오드를 동작시킬 DC bias 회로로 구성되어 있다. 구조적인 대칭/비대칭은 두 갈래로 갈라지는 Y자 형태의 급전부 왼쪽 라인에 삽입된 핀 다이오드의 on/off 상태에 의해 결정된다. 제안된 재구성 안테나는 핀 다이오드가 on 상태이면 급전부의 갈라지는 두 마이크로스트립 라인의 길이가 같아지게 되어 안테나는 선형 편파 특성을 나타낸다. 반면에, 핀 다이오드가 off 상태이면 급전부의 갈라지는 두 마이크로스트립 라인 중 한 쪽 라인의 길이가 나머지 한 쪽 라인의 길이보다 상대적으로 짧아지게 된다. 그러므로 안테나는 원형 편파 특성을 나타낸다. 측정 결과로부터 제안된 안테나는 좋은 임피던스 매칭과 축비 특성을 나타내며, 같은 주파수 대역에서 쉽게 편파 변환할 수 있다는 것을 확인할 수 있다.
