The purpose of this study is to compare the cognition of SIDS as the first step for decreasing the SIDS death rate for the infant and for activity of infant-care in Korea. Participants were 409 child care center directors and 146 parents from 500 child care center directors and 200 parents who using child care center facilities for their children in Seoul. For analysis of research questions, frequencies, Cronbach $\alpha$, t-test,One-way ANOVA, Scheffee test were used with SPSSWIN 15.0. Through this study, we find the child care center directors have good cognition for it, but their effort for SIDS prevention is limited, because they don't have any official prevention education from authorized training center. Even though the parents have a low awareness for SIDS prevention than child care center directors, but they have high score in endeavor for SIDS precaution. Both child care center directors and parents want to receive systematic information from government side. Our infant should have a opportunity to grow up health and stability from reducing the risk of SIDS. In western countries such as U.S.A., U.K. and Japan have studied to decrease the SIDS death rate from thirty years ago, they have already government and social organization for preventing the SIDS. Nowadays, as you know well, our country birth-rate is falling by 1.08, therefore, it is important to decrease the infant death rate for keeping with our population. Also, it is relevant to the child-welfare and the child-safety and more better the child-care.

Purpose: The study was performed to evaluate effects of aroma therapy on the anxiety, blood pressure and pulse of uterine leiomyoma patients before surgery and to apply it as the actual nursing intervention. Method: From Aug1st to Nov. 30th, 2007, the experimental group (n=30) and the control group (n=30) were selected in 1 hospital, Busan. Lavender and Bergamot oil mixed together at a 3:2 ratio was applied to the experimental group two times at 8-9 pm the day before surgery and twice 30 minutes before the surgery. Anxiety, VAS, blood pressure, and pulse were measured to evaluate the effects of aroma therapy. The data analysis was done using the SPSS/PC 12.0 program using chi-square test and t-test. Results: Hypothesis 1 was supported. The VAS of the experimental group was lower than control group after aroma therapy. Hypothesis 2 was partly supported. The systolic blood pressure and pulse of experimental group was significantly decreased, but diastolic blood pressure wasn't difference. The VAS, systolic blood pressure and pulse of control group were increased. Conclusion: The study verified that the aroma therapy is a very effective nursing intervention that can reduce anxiety before surgery. It is recommended to apply aroma therapy actively to patients experiencing anxiety before surgery procedure.

기후변화로 인한 수문사상의 특성이 급격하게 변동되는 것은 이미 많은 연구로 인해 밝혀졌다. 이중, 강우사상의 경우 연강우량의 증가에도 불구하고, 일최대강우량 또는 강우강도나 강우집중률이 비교적 더 크게 증가하면서 직접유출 부분이 증가하고 침투량이 감소하면서, 즉 총강우의 유역출구로 나가는 부분이 증가하면서, 갈수기의 지하 및 하천수위는 예년에 비해 더욱 하강하고 있는 실정이 국가지하수관측망이나 하천수위 자료로서 관측되고 있다. 이는 지하수위의 변동특성이 강우패턴의 변화로 인해 분명히 영향을 받고 있다는 사실을 자료로서 입증하고 있다고 할 수 있다. 본 연구는 국가지하수 관측망 중 낙동강유역에 위치한 관측소를 대상으로 관측자료를 검토한 결과 총 43개의 관측소를 선정하여 암반층 36개, 충적층 19개로 관측정별 자료 수집을 하였으며, 연최대, 연평균, 연최저 지하수위에 대한 경향성 및 유의성 검정을 실시하였다. 유의성 검정은 t-test를 실시하였다. 연 평균지하수위를 기준으로 암반층은 27개 관측소가 하강하였고, 이 중 유의수준 5% 이내에 유의하며 하강하는 지점은 9개로 나타났다. 충적층은 16개 관측소가 하강하는 경향을 나타냈으며, 이 중 12개 관측소가 유의수준 5% 이내에 유의하는 것으로 나타났다. 지하수위의 하강하는 경향성이 뚜렷한 지역은 지하수의 고갈과 함께 인근하천의 건천화 그리고 지반침하나 해안지방인 경우는 염수침입이 일어날 가능성이 큰 지역이므로 향후 이에 대한 대책이 세워져야 할 것이다.

To investigate the effect of food habits on the bone state of the senior citizens, two groups were tested: one(111 senior citizens) was healthy ordinary senior citizens over 65 years old and the other(51 senior citizens) was patients distinguished as having osteoporosis. The present dietary intake was estimated by a 24-hr recall method, and individual history. For the data analysis, percentages and frequencies were calculated and χ²-test was undertaken to test the relation among values. The following results were obtained: patient group with osteoporosis was less in height and weight than the group of ordinary senior citizens(160.33cm, 59.99kg). It was much less than the average Korean senior citizens(158cm, 54.9kg). Food appetite in the group of patient was worse than that of ordinary senior citizens group. According to their dietary history(58.8%), the food intake pattern was most of vegetables(62.0%). Eventhough they haven't been intaken milk after recognizing of their osteoporosis(74.5%). Most of them didn't improve their food habits to help Ca metabolism. Also they have depress of their life(50%). All subjects certainly took insufficient energy, Ca, protein from their diets. Moreover the major source of Ca were vegetables, seaweeds and legumes.

Objectives: This study aimed to provide basic data on ways to facilitate effective communication between patients and dental hygienists, to improve the job satisfaction of dental hygienists, and to reduce the turnover rate among dental hygienists. Therefore, a comparative analysis of the perception of dental hygienists' emotional labor was conducted targeting patients and dental hygienists. Methods: Data were collected from August 1 to September 20, 2018, from 367 participants, including 216 dental hygienists and 151 patients residing in Gwangju, Jeonnam. Using the co-orientation model, their perception of dental hygienists' emotional labor was analyzed through the independent t-test and paired t-test. Results: With reference to objective consistency, patients showed a higher perception of dental hygienists' emotional labor than dental hygienists did, indicating that the former perceived the emotional labor more negatively. Regarding accuracy, there were significant differences in dental hygienists' response to six questions, while the same was observed for 11 questions for patients. Thus, the accuracy of dental hygienists was relatively higher than that of patients. Conclusions: To help dental hygienists perform dental health prevention activities more actively, consistently, and happily, and to establish commitment and professionalism in dental hygienists to enhance national dental health. Additionally, it would be necessary to sustain continuous research interest on measures for understanding the co-oriented relationship between patients and dental hygienists, and to solve the negative elements of dental hygienists' emotional labor.
