The longitudinal study was done to study the effect of length of lactation on mineral content of breast milk and to find out basic data on nutritional status for infants and lactation women in Korea. Milk was collected from primiparae(n=10) and multiparae(n=6) at 0.5, 1, 2, 3, 4 and 5 months postpartum. During lactation the content of total ash, calcium, phosphours decreased significantly (;<0.001), but magnesium increased significantly (p<0.001). Total ash, calcium, phosphrus and magnesium contents of breast milk per 100ml were as 0.22g, 27.25mg, 14.67mg and 2.77mg in total lactating women(n=16), respectively. These contents were not significantly different between primiparae and multiparae. A ratio of calcium to phosphorus was about 1.88:1 in breast milk and 0.50:1 in maternal dietary intake. No correlation was found between maternal dietary intake and mineral content of breast milk.

In this study longitudinal of the taurine content in the human milk of 23 Korean lacto-ovo-vegetarian women was studied during the lactating periods of the 15th, 30th, 60th, 90th, 120th and 150th day after delivery. The results of the study on primiparae and multiparae studied separately are as follows: 1) The taurine content of the primiparae per 1ml of human milk was 356.1nmole on the 15th day, 238.6 nmole on the 30th day, 249.6 nmole on the 60th day, 148.7 nmole on the 20th day, and 139.6 nmole on the 150th day. There was a significant decrease in the measns. 2) The taurine content of the multiparae per 1ml f human milk was 401.6 nmole on the 90th day, 189.9 nmole on the 120th day, and 159.8 nmole on the 150th day. There was a significant decrease in the measns. 2) The taurine content of the multiparae per 1ml of human milk was 401.6 nmole on the 15th day, 342.3 nmole on the 30th day, 273.2 nmole on the 60th day, 248.6 nmole on the 90th day, 189.9 nmole on the 120th day, and 159.8 nmole on the 150th day. There was a significant decrease in the measns. The multipareas had higher taurine content in every lactating period than the primiparae but there was not a significant difference. The correlation between the changes durinig lactating periods and the taurine content was negative. The correlation coefficient of the primiparae was -0.641 and that of the multiparae was -0.753. The overall correlation coefficient of the primiparae and the multiparae is -0.644, decreasing significantly up to the 150th day.

본 연구의 목적은 1980년대 중반부터 약 10여년 동안 현저한 출생시 성비불균형을 경험한 대구지역의 경산부들을 대상으로 아들을 낳기 위한 노력에 미치는 요인들을 밝히는데 있다. 1998년 4월부터 6월까지의 3개월동안 대구지역의 6개 종합병원에 내원한 임산부들 가운데 출산 경험이 있는 경산부를 대상으로 실시한 설문조사자료를 사용하였으며 경산부의 아들 낳기 노력에 영향을 미치는 요인들을 규명하기 위하여 로지스틱 회귀분석을 도입하였다. 연구결과에 따르면 대구지역의 경산부들은 여성에 대한 성차별을 많이 느끼고 있을 뿐만 아니라 아들 선호의식 역시 상당히 높은 것으로 나타났다. 연구대상자들의 24.7%는 임신 전 아들을 낳기 위한 노력은 한 경험이 있다고 응답하였으며 12.2%는 태아의 선별적 인공유산을 통하여 아들을 낳기 위한 노력을 시도한 경험이 있는 것으로 밝혀졌다. 로지스틱 회귀분석 결과에 따르면 여성에 대한 성차별, 아들선호의식, 자녀 가운데 아들이 없는 경우, 인공임신중절수술 및 연령 등의 요인들이 조사대상자들의 아들을 낳기 위한 노력에 통계적으로 유의미한 영향을 미치는 것으로 밝혀졌다. 이러한 결과로 미루어 보아 대구지역의 출생시 성비가 다른 지역보다 높은 이유는 아들을 선호하고 여성을 차별하는 의식의 기반이 되었던 과거 농경 중심사회의 오랜 전통이 상대적으로 많이 남아있는 보수적인 성향의 결과라 할 수 있다. 뿐만 아니라 이러한 성향이 소자녀관으로 변화된 현대에 있어도 아들 하나는 꼭 낳아야겠다는 강한 집념이 현대 의료기기의 발달 및 보급과 의료인들의 영리추구와 이해관계가 부합됨으로써 생겨난 결과로 볼 수 있다. 시설입소의 인종간 차이를 통제할 때 소수인종노인이 백인노인보다 쉽게 자녀동거에서 단독거주로 이행하는데 이는 소수인종에서 가족부양체계가 불안정함을 의미한다. 또한 빈곤시에 소수인종 노인은 백인노인에 비하여 쉽게 자녀와 떨어져 살게 된다. 이러한 결과는 소수인종 노인에 대한 가족의 지원은 그 가족의 경제적 제약속에서 매우 안정적이지 못함을 시사한다. 못함을 시사한다.로 판단된다.(가솔린, 등유, 경유)로 회수 가능하였다..01 (n=10), 4세포기배는 1.05$\pm$0.09 (n=10)를 나타냄으로써 수정란의 단계마다 $E_2$의 반응 결과가 차이가 남을 알 수 있었다. 4. $E_2$농도 곡선에서 PMSG 처리 후 $E_2$의 혈중농도는 계속적인 상승을 보이다가 배란시기에 최고치를 나타내었으며, 배란 후 다시 감소하여 8세포기에서는 급격한 감소현상이 나타났다. 이후 다시 상실기를 거쳐 배반포기 임신기간동안 $E_2$의 농도가 상승하였다. 5. $E_2$처리 후 세포내 $Ca^{2+}$ 농도변화의 결과로, $E_2$를 처리하지 않은 난자들의 세포내 $Ca^{2+}$ 농도는 836.4$\pm$131.2 (n=10), $E_2$를 처리한 난자들은 1736.4$\pm$192.0 (n=10)로써 유의한 (P<0.05) 차이를 보였다. 이상의 결과로부터 $E_2$처리에 의한 세포내

This study was conducted to assess the attitude of pregnant women toward delivery method, understanding of the reason for determining her own delivery method, participation in decision-making process and satisfaction with delivery method after labor. Study subjects were 693 pregnant women who had visited obstetric clinic for prenatal care in the last month of pregnancy in one general hospital and one obstetrics-gynecology specialty hospital in Taegu city from February 1 to March 31 in 1998. A questionnaire was administered before and after labor and a telephone interview was done one month after labor. Proportion of women who had health education and/or counselling about delivery method during prenatal care was 24.0% and this proportion was higher for women who had previous c-section(35.5%) than others. Women thought vaginal delivery is better than c-section for both maternal and baby's health regardless of previous delivery method. About 90% of primipara and multiparous women who had previous vaginal delivery wanted vaginal delivery for the index birth, while 85.6% of multiparous women who had previous c-section wanted repeat c-section. Reasons for choosing c-section in pregnant women who preferred vaginal delivery before labor were recommendation of doctors(81.9%), recommendation of husband (0.8%), agreement between doctor and pregnant woman(4.7%), and mother's demand (12.6%). Reasons for choosing vaginal delivery were mother's demand(30.6%) and no indication for c-section(67.2%). Reasons for choosing c-section in pregnant women who preferred c-section before labor were recommendation of doctors(76.2%), mother's demand(20.0%), recommendation of husband(1.3%), and agreement between doctor and pregnant woman(2.5%). Of the pregnant women who had c-section, by doctor's recommendation, the proportion of women who had heard detailed explanation about reason for c-section by doctor was 55.1%. Mother's statement about the reason for c-section was consistent with the medical record in 75.9% . However, over 5% points disparities were shown between mother's statement and medical record in cases of the repeat c-section and mother's demand. In primipara and multiparous women who had previous vaginal delivery, the delivery method for index birth had statistically significant association with the preference of delivery method before labor(p<0.05). All of the women who had previous c-section had delivered the index baby by c-section. Among mothers who had delivered the index baby vaginally, 84.9% of them were satisfied with their delivery method immediately after labor and 85.1% at 1 month after labor. However, mothers who had c-section stated that they are satisfied with c-section in 44.6% immediately after labor and 42.0% at 1 month after labor. Preferred delivery method for the next birth had statistically significant association with delivery method for the index birth both immediately after labor and in 1 month after labor. The proportion of mothers who prefer vaginal delivery for the next birth increased with the degree of satisfaction with the vaginal delivery for the index birth but the proportion of mothers who prefer c-section for the next birth was high and they did not change significantly with the degree of satisfaction with the c-section for the index birth. These results suggest that the current high technology-based, physician-centered prenatal and partritional cares need to be reoriented to the basic preventive and promotive technology-based, and mother-fetus-centered care. It is also suggested that active involvement of pregnant woman in decision-making process for the delivery method will increase the rate of vaginal birth after c-section and decrease c-section rate and improve the degree of maternal satisfaction after delivery.

경산 임당유적에서 출토된 목제 갑옷틀은 수침된 상태로 출토된 목제유물로 재질이 매우 취약하여, 대기 중에 노출되면 급속도로 건조가 진행되어 곧바로 수축 변형이 일어나 유물로써 가치를 잃어버리게 된다. 특히 목제 갑옷틀은 오랜 매장기간동안 목질부의 분해가 많이 진행되어 재질이 취약할 뿐 아니라 원통목을 가공한 것이어서 건조 과정에서 수축변형이 발생우려가 높다. 따라서 목제 갑옷틀은 건조변형이 적고 치수안정화가 우수한 처리법을 적용하여야 한다. 따라서 목제 갑옷틀은 t-butanol 용액을 용제로 PEG#4000 40%로 함침 전처리 후 진공 동결건조법으로 보존처리 하였다.

While excavating relics in Uksu-dong of Daegu and Oksan-dong of Gyeongsan, 38 units of the earthen kilns used during the Three Kingdom era were discovered. Nine pieces of charcoal were collected for examination from 8 kilns out of 38. The result identified 4 pinus densiflora, 3 Quercus sp. and 1 Platycarya strobilacea Sieb. The remaining 1 tree could not be identified because most of the remaining wood was mixed and tangled with clay.

We dealt with the Wooden Shoes as a tool in the first chapter. You can doubt about the Wooden Shoes as a tool, which they were in Japan and China not Korea, strictly speaking, if they are real shoes or not. But anyway they had components of the Wooden Shoes in shape(form) or function, so it was expressed in the head part, cause of the possibility that Wooden Shoes as a tool are the previous stage of Wooden Shoes as shoes, though are not identified yet. In the second chapter, we dealt with the Wooden Shoes as shoes fundamentally. Recently, the Wooden Shoes of Shilla and Baekje were dug out each in Kyungsan-city Im-dang-dong and Buyeo-gun Neungsan-lee. Even though they were contemporary neighborhood countries, they had much differences in their forms of Wooden Shoes. While the Wooden Shoes of Baekje and the ancient Wooden Shoes of Japan are surprisingly alike. So we have tried to identify with the politic and diplomatic relation of Korea and Japan, through various literature records.

본 연구는 최근 기후변화로 인해 유출량이 많이 증가하고 있으며, 또한 하도의 제내측에 많은 피해가 발생하고 있다. 우리나라의 하도는 산지위치하고 있으며, 만곡의 형상을 많이 지니고 있다. 또한 유출량의 증가로 하도 만곡부에 하상의 퇴적으로 인해 월류 및 제방이 파괴 되는 현상도 발생되고 있다. 만곡부의 흐름은 만곡도의 수공구조물을 설치하므로 유수의 흐름에 민감하게 변화하여 흐름변화를 예측하기 어렵다. 그래서 자연하고 만곡부에 하상의 변화에 따른 수리학적 문제와 제내측의 안정성을 확보하기 위해 만곡지점에 수제를 설치하여 하도의 흐름과 하상의 안정성에 필요하다고 사료되어 연구를 하였다. 본 연구는 만곡지점에 수리실험 모형을 설치하여 결과를 도출하는 방법도 있으나, 축소모형은 하도의 특성을 반영하기 결과도축에 제약이 있어 금회 연구는 수치모형은 2차원 수치모형인 RMA-2를 사용하여 하도의 특성을 파악하고자 한다. 먼저 만곡형상이 뚜렷한 지점을 파악하고 하천설계기준의 수제를 설치하여 흐름의 변화 및 유속변화를 분석하고 만곡부에서 기준수제의 길이를 여러 CASE로 변화를 주어 수리학적 특성을 분석하고자 하며, 이에 따른 수제부에서 발생하는 퇴적구간과 범위, 최대유속지점과 세굴지점에 대한 연구를 진행하여 하도 만곡부에 수제를 설치하여 합리적인 결과를 제시 할 수 있으며, 설계실무와 하천방재 관련 문제에서도 반영하여 이용 될 수 있을 것이다.

Flank Pain is a leading indicator of renal and upper urinary tract disease or trauma, and rarely results from pelvic congestion syndrome. Although pelvic congestion syndrome occurs commonly in multi-parous women, pelvic congestion syndrome should also be considered as the cause of flank pain in an adolescent girl. We report the first case of pelvic congestion syndrome presenting with chronic left flank pain in an adolescent girl.
