Purpose: Immediate identification of vascular injury requiring embolization in patients with pelvic bone fracture isn’t an easy task. There have been many trials finding indicators of embolization for patients with pelvic bone fracture. Although Young and Burgess classification is useful in decision making of treatment, it is reported to have little value as indicator of embolization in major trauma patients. The aim of this study is to find out Young and burgess classification on predicting vessel injury by analzyng pelvic radiograph taken from major trauma patients with pelvic bone fracture. Methods: Among major trauma patients with injury severity scores (ISS) higher than 15 who visited our emergency room from January 2011 to June 2014, 200 patients were found with pelvic bone fracture in trauma series and thus pelvic CT angiography was taken. Setting aside patients with exclusion criteria, 153 patients were enrolled in this study for analysis of Young and Burgess classification. Results: The most common mechanism of injury was lateral compression in both groups. There was no statistical significant difference in Young and Burgess classification (p=0.397). The obturator artery was the most commonly injured artery in both groups. Six patients had more than one site of bleeding. Conclusion: Prediction of transcatheter angiographic embolization using Young and Burgess classification in severe trauma patients is difficult and requires additional studies.

The purpose of health care is to promote human physical, emotional and social development through the sound life style, the prevention and treatment of desease, and rehabilitation. In order to meet the needs of human health effectively, delivery of community health care services must be applied to all the people, not only just to selested groups and individuals. Here we have the new role of the professional nurses in community. The purpose of this study was to determine the present general health status of the citizens of the district served by Ewha Womans University Community Health Nursing Services in Sin Chon area. It was hoped that this information should contribute to the more accurate assessment of health needs to develop community health nursing services toward the improvement of health care. Data was collected from a sample of 1,000 families (4629 persons) from April to October, 1975. The results obtained were as follows: 1. Of the ,1000 families, the average number of members per family was 4.6 persons. Conjugal families living apart from their extended families numbered 83.7% of the total. The average number of children per family was 2.5. 2. The ages of thesample of 4629 persons ranged from 3 months to 99 years old, and the largest distribution fell into the 5∼40 age group. Among the household heads, the largest number fel linto the 40∼59 age group, 44.7%. Of the respondents, 51.0% were male and 49.0% were female. There were many more men named as household heads, 92.1% than women, 7.9%. More respondents (55.7%) were single than married (40.1%), but 89.0% of household heads were married. 3. The educational preparation of the group ranged from elementary school graduates to university graduates. 17.0% of the household heads were elementary school graduates. Some respondents (6.1%) had no formal education. More than half of the respondents had no religious affiliation, 72.2%. 4. The majority of household heads, 82.6% were wmployed. The unemployed household heads accounted for 17.4% of the group. Not a small proportion (40.5%) of households were living in rented accommodation of one to two rooms averaging four phyong (noe phyong is six feet square). 5. Half of the households, 50.6% had used a hosoital or medical clinic for health care. Among those having health care, 42.5% had obtained health care only for the children. Difficult economic circumstances was the cause to limit health care to the children in a family (X^2=45.57>X^2_3(905)=781). Only 4.4% of the households reported that the entire family received health care. Care was limited to the ill person in 3.1% of families. Of those families receiving health care, 53.7% reported that their care was regular. When member of families numbered five or more persons, there was a tendency that they do not receive regular care (X^2=9.60>X^2_2(0.05)). 6. In the 942 families with children five years old and under, almost all (90.7%) had some immunization, but 46.6% had not had the required immunization. Some had none, 5.8%. 7. Of the 2164 reprodnctive age women, 67.3% had neither prenatal nor postnatal health care. The rest, 34.4% conulted a hospital or medical clinic about delivery. More than half (54.5%( had been delivered at home with the assistance of relatives (3.8%), or husbands (1.7%). Not a few, 24.3% had no help at all with deliveries. 8. Accidents had affected 1.4% of the households (65.1% male and 34.9 flmale). Accidentstook place on the street (55.5%), at home (30.2%), at work (11.1%), and at school (3.2%). Those suffering accidents generally recrived emergency treatments at hospitals and medical clinics, 73.0%. A small number (7.9%) were treated with folk remedies. Among respondents, 4.8% had some illness and 0.4% had some deformity. 9. Fewer families, 43.5% had consulted with some agency about family planning. The agencies used were a hospital or medical clinic(28.3%), a health centre (48.0%), a pharmacy (18.0%) and Ewha Community Nursing Services (5.3%). Families with three or more children had the tendency of using the health center, pharmacy and Ewha Community Nursing Services while those with two or fewer children of using the hospital or medical clinic (X^2=59.10>X^2_2(0.05)=5.99). At the time of the survey, 36.0% of the families reported that they used a family planning method. The primarily reported was the oralcontraceptive, 38.6%. Other methods were the IUCD, 19.2% and condoms, 9.7%. Use of a family planning method had been interrupted for 33.0% of experienced families. 10. Among the mothod in the householod sample, 25.0% stated desire for a permanent contraceptive method. Half of these women, 51.2% expressed confidence that they would have a surgical cintraceptive procedure. Recommendations included the establishment of an economic community midwifery service and a community centered accident prevention programme.

성장기 아동에서 Cervical Headger 사용시 골격적 변화 양상에 대한 연구
현하영,이진우,차경석 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.5
성장기 아동의 Class II 부정교합에서 과도한 성장의 억제, 미약한 성장의 촉진으로 성장 시기에 적절히 치료하는 것이 가장 효과적이며 좋은 치료 방법이다. 이러한 방법 중 가장 적절히 쓰이는 장치 중 Cervical headgear의 사용을 들수 있으며 악골에 효과적으로 적용된다. 그러나 장치의 부작용이라 할 수 있는 수직적 성장의 과잉을 볼 수 있는데 이에 대해 많은 서학들의 연구가 시행되어 왔다. 본 연구는 Cervial headgear의 상하악골에 대한 효과를 분석하고 Lower facial height를 기준으로 증가군(>0)과 증가하지 않은 군 ( ≤0)으로 나누어 골격적 특성을 알아보기 위해 단국대학교 부속 치과병원에 내원한 성장기 아동의 II급 부정교합환자 25명을 대상으로 cervical headgear를 사용한 결과 다음과 같이 다소의 지견을 얻었기에 보고하는 바이다. 1. 상악골의 전방 성분이 억제되었고, 구개 평면의 전방이 하방으로 tipping되었으며 상악 제 1대구치의 후방 이동이 있었다. 2. 하악골의 두개저에 대한 상대적인 전방 이동이 있었으며 상악에 대한 하악 제1대구치의 상대적인 전방 이동이 있었고 하악골의 alveolar growth에 의한 수직적인 증가가 있었다. 3. 전안면 고경과 후안면 고경이 각기 유의하게 증가했으나 안면 고경 비율에는 유의성이 없었다. 4. Lower facial height가 증가한 group이 증가하지 않은 group보다 ramus의 길이가 짧고 palatal plane angle이 더 작았으며 상악 제 1대구치의 후방 이동량이 더 많았다. This study was to investigate the horizontal & vertical bone change pattern when using cervical headgear in Class II malocclusion of growing children and compared the skeletal features between the group with increased lower facial height and the group without increase in lower facial height. The results are as follows ; 1. Forward growth of maxilla was inhibited, downward tipping of anterior palatal plane could be seen and distal movement of maxillary first molar was observed. 2. There was relative forward movement of Mandible against the Maxillary cranial base, and relative forward movement of mandibular 1st molar against the Maxilla and vertical increase due to alveolar growth of Mandible. 3. There was significant increase in anterior and posterior facial heights but the ratio of facial height showed no significant difference. 4. The group with increased lower facial height has shorter ramus length, than the smaller palatal plane angle, and more distal movement of Maxillary 1st molar than the group without increase Ha-young Hyun.

Structural Elucidation of Rhamnogalacturonan II-Rich Polysaccharide Purified from Ginseng Berry
Ha Young Cha,Su Hwan Kim,Kwang-Soon Shin 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10
The aim of this study was to elucidate the micro-structure of polysaccharide isolated from ginseng berry. GBW-II was purified by the hot water extraction, ethanol precipitation and gel filtration from ginseng berry. The MW of GBW-II was estimated as 11 kDa, and it consisted of 14 different sugars which included rarely observed sugars such as 2-O-methyl-xylose, apiose, aceric acid, Kdo and Dha. Methylation analysis indicated that GBW-II comprised 21 different glycosyl linkages such as 2,3,4-linked Rhap, 3,4-linked Fucp and 3’-linked Apif, being characteristic of rhamnogalacturonan II (RG-II). The primary structure was elucidated by sugar composition, methylation analysis, oligosaccharide analysis and sequencing using GC, GC-MS, LC-MS and ESI-MS/MS. Sequential degradation using partial acid hydrolysis indicated that GBW-II contained Rhap-(1→5)-Kdo, Araf-(1→5)-Dha, an AcefA-containing nonasaccharide, and an uronic acid rich oligosaccharide side-chains in addition to an α-(1→4)-galacturono-oligosaccharide main chain. In conclusion, GBW-II was finally identified to be a polysaccharide belonging to RG-II.

Cha, Ji-Young,Park, Eun-Young,Kim, Ha-Jung,Park, Sang-Un,Nam, Ki-Yeul,Choi, Jae-Eul,Jun, Hee-Sook The Korean Society of Ginseng 2010 Journal of Ginseng Research Vol.34 No.3
Recent studies have indicated that $\beta$-cell dysfunction and insulin resistance are important factors in the development of type 2 diabetes. The present study investigated the effect of extracts from different parts of white, Taegeuk, and red ginseng root on insulin-stimulated glucose uptake in muscle cells and proliferation of $\beta$-cells. Extracts of the fine roots of Taegeuk ginseng significantly enhanced glucose uptake compared with the control. White ginseng lateral root extracts enhanced insulin-induced glucose uptake. Proliferation of $\beta$-cells was significantly increased by Taegeuk ginseng main and lateral root extracts and by red ginseng lateral and fine root extracts. In conclusion, different root parts of white, Taegeuk, and red ginseng differentially affect glucose uptake and pancreatic $\beta$-cell proliferation.
