  • A women's meaning about labor and delivery may influence the process of childbirth and performance of the maternal role. Therefore, negative meaning about the birth experience may have a negative impact on the childrearing. The purpose of this study is to explore the meaning of labor and delivery for the strategies of nursing intervention in positive childbirth experience. The data were collected through the in-depth interviews of 10 nursing college women on Jeju Island from October 2000 to January 2001. The interviews were conducted by investigator in the class room after school hours. Each interview lasted for about 30 minutes on average. Subjects were interviewed one at a time. The interviews were recorded with the consent of the subject. The data were analyzed by means of Giorgi's phenomenological analysis methods and catagorized according to the similarities of its contents. The investigator read the data repeatedly to identify the themes and the main meanings. Eight main meanings were identified as follows : 1)pain 2) shame and disgust 3)load 4)naturality 5)unreality 6)happiness 7)anxiety 8)maturity. Under these main meanings there were seventeen themes. I. Pain : (a) It's too painful (b) I don't want to deliver II. Shame and Disgust : (a) I am shameful (b) I am hateful III. Load : (a) I don't feel free (b) I have responsibility IV. Naturality : (a) It's in order to obtain a child (b) It's natural for women (c) It's a destiny of women V. Unreality : I don't feel real VI. Happiness : (a) I am glad (b) I am happy (c) It's miraculous VII. Anxiety : (a) I am anxious (b) I am worried VIII. Maturity : (a) I understand parents (b) I feel great. The results of the study will provide basic data for positive childbirth experience.

  • 도로분류체계는 도로의 기능 및 설계기준을 정의하기 위한 기초가 된다. 현재 우리나라에서는 도로의 소재지역, 도로의 기능 등 다양한 기준에 따라 도로를 구분하고 있다. 본 연구에서는 다양한 교통지표를 이용하여 일반국도를 분류하고, 도로 유형별 교통 특성을 규명하고자 하였다. 이를 위해 상시교통량 조사지점을 대상으로 다양한 교통지표를 이용하여 혼합모형을 통해 일반국도를 유형별로 분류하고 교통특성을 분석하였다.적용된 변수는 총 8개로 AADT(연평균 일교통량), $K_{30}$(설계시간 계수), 중차량 비율, 주간 교통량 비율, 첨두율, 일요일 계수, 휴가철 계수, 그리고 COV(변동계수)이다. 요인분석 결과 2개의 요인 즉, 교통량 변동 특성 요인(COV, $K_{30}$, 휴가철계수, 주간 교통량 비율, 일요일계수, 첨두율, AADT)과 중차량 및 방향별 특성 요인(중차량 비율, $D_{30}$)이 추출되었다. 306개 상시지점이 3개의 그룹으로 구분되며, 이에 대한 교통특성을 분석한 결과 그룹 I은 도시부도로, 그룹 II는 지방부도로, 그룹 III은 관광부도로로 판단된다. AADT는 도시부도로가 30,000대, 지방부도로가 16,000대, 그리고 관광부도로가 5,000대 수준인 것으로 분석된다. 그룹 III은 일요일과 휴가철의 평균 일교통량이 연평균 일교통량보다 매우 많은 전형적인 관광 위락 도로임을 알 수 있다. 시간대별 교통량 분석결과 평일 교통량 패턴은 그룹 I이 비교적 오전 및 오후 첨두현상이 강하게 나타나며, 그룹 II와 그룹 III은 첨두현상이 거의 나타나지 않는 것으로 분석된다.

  • Background: Recurrent abdominal pain (RAP) is one of the frequent complaints in general practice, particularly in pediatrics and is among the common cause of referral to gastroenterology clinics. Purpose: This study is designed to investigate the effects of probiotics for the treatment of RAP and desired therapeutic outcomes. Methods: One hundred twenty-five children with the diagnosis of RAP according to Rome III criteria for irritable bowel syndrome (IBS), functional abdominal pain (FAP), functional dyspepsia (FD), and abdominal migraine (AM), were enrolled in this double-blind randomized controlled trial. Results: Sixty-five subjects received probiotics, and others received placebo treatment for 4 weeks. Lactobacillus reuteri was therapeutically effective in 32 patients compared to 8 patients, responding to the placebo treatment. Compared to baseline, all pain-related variables showed a significant reduction for the IBS and FD at the end of the 4th week. However, it did not respond well in FAP and AM groups. Pain-related outcomes such as, frequency of the pain, severity, and duration of the pain were decreased following the probiotic treatment. No therapeutic response was seen in AM group after the administration of probiotics. L. reuteri significantly led to pain relief in the overall population, and also in FAP, FD, and IBS subgroups. Conclusion: L. reuteri probiotics are likely to lead to RAP relief and can be recommended for the treatment of functional gastrointestinal disorders.

  • In this paper, present status of super high-efficiency tandem solar cells has been reviewed and key issues for realizing super high-efficiency have also been discussed. In addition, the terretrial R&D activities of tandem cells, in the New Sunshine Program of MITI(Ministry of International Trade and Industry) and NEDO(New Energy and Industrial Technology Development Organization) in Japan are reviewed briefly. The mechanical stacked 3-junction cells of monolithically grown InGaP/GaAs 2-junction cells and InGaAs cells have reached the highest efficiency achieved in Japan of 33.3% at 1-sun AM1.5. This paper also reports high-efficiency InGaP/GaAs 2-junction solar cells with a world-record efficiency of 26.9% at AM0, 28$^{\circ}C$ and radiation damage recovery phenomena of the tandem cell performance due to minority-carrier injection under light illumination or forward bias, which causes defect annealing in InGaP top cells. Future prospects for realizing super-high efficiency and low-cost tandem solar cells are also described.

  • Cobalt(Ⅲ) ion gives two step waves with $E_{1/2}$-0.1V(?)(vs.S.C.E.) and $E_{1/2}$-1.37V(vs. S.C.E.) from a base electrolyte consisting of 0.1 M TEA+sodium borate+0.0002% gelatin. The first wave results from the reduction Co(Ⅲ) to Co(Ⅱ). The second wave corresponding to the reduction Co(Ⅱ) to Co(0) and this wave is diffusion controlled. The diffusion current constant of the second wave is 2.7. Under these-conditions, diffusion current of the second wave is proportional to the concentration of Co (Ⅱ) in the range of $10^{-3}{\sim}10^{-4}$ M.

  • Two allelotypes of sMDH variation, namely A and B type, are known in the dark chub, Zacco temmincki. We attempted to clarify their probable functional enzymatic difEerence with temperature change. Two types of sMDH were purified separately by successive chromatography on DEAE-cellulose and blue 2-Sepharose amEnity columns, and their ensymatic activities to temperature change were measured. Q10 of Vmax and Vmax/Km were significantly different between two types, i.e. A type being higher in Q10 values than B type. Based on the result it is assumed that A type may be more sensitive to temperature change than B type.
