The Associations between income, informal social networks, and health among older adults in South Korea: A multi‐group analysis based on the level of age‐friendly environments

Sue‐Lynn Kim,Ju‐Hyun Kim,Kyong‐Hee Ju 한국사회복지학회 2019 Asian Social Work and Policy Review Vol.13 No.3

The aim of the present study was to empirically investigate the role of age-friendly environments (AFE) on the associations between income, informal social networks, and health among South Korean older adults. We used data from the “2017 Age Integration Survey” collected nationally and ultimately analyzed 615 older adults over 50 years of age. Structural equation modeling and multi-group analysis were used to test the hypothesis. Specifically, two groups of perceived levels of AFE (top 25%, bottom 25%) were compared in order to examine the moderating effects. The results indicated that poor income and scarce informal social networks each had a significantly adverse impact on health. However, the effect of income on health was no longer significant for older adults living in environments that were more age-friendly. In both groups, the presence of fewer informal social networks adversely impacted health, although the sizes of the effects decreased when the level of AFE perceived by older adults was improved. Finally, several implications of the study findings were discussed.

두개봉합부의 조기융합으로 알려진 Craniosynostosis는 두개봉합부 주위 조직들 사이의 조화로운 상호 작용이 파괴되었을 때 야기될 수 있다. 흥미롭게도 FGF receptor들, 특히 FGFR2의 point mutation은 여러 가지 형태의 craniosynostosis 증후군과 연관되어 있어, FGFR가 두개봉합부를 포함한 두개골 성장 발달과정에 중요한 유전자임을 시사하고 있다. Mouse 두개봉합부의 초기형태발생시 FGFR 유전자들의 기능을 알아보기위해, in situ hybridization 방법을 이용하여 FGFR2(BEK) 및 골아세포분화의 초기표지자인 osteopontin이, 태생기(E15-18)에서 출생후(P1-P3)까지, 두개골의 시상봉합부에서의 발현양상을 조사하였다. FGFR2(BEK)은 osteogenic front에 강하게 발현되었으며, osteopontin은 parietal bone의 exo-, endocranial부위에서 발현되었으나, parietal bone의 성장가장자리인 osteogenic front에서는 관찰되지 않았다. 두개봉합부에서의 FGF-mediated FGFR signaling의 역할을 좀더 심도깊게 조사 하기위해 E15.5 mouse의 두개골을 이용하여 in vitro 실험을 시행하였다. 흥미롭게도 osteogenic fronts 및 시상봉합부의 간엽조직 중앙에 FGF2 - soaked beads를 점적하여 36시간 기관배양한 결과, bead주위 조직들의 두께 및 세포수가 증가되었으며, osteogenic fronts 상에 FGF4 beads를 올려놓은 경우, 시상두개봉합부 중앙에 점적된 FGF4 beads나 BSA control beads에 비해, 골성장이 촉진되어 시상두개봉합부의 부분적인 소멸을 관찰할 수 있었다. 이와 더불어 FGFR2 beads는 osteopotin 및 Msxl 유전자의 발현을 유도하였다. 이 결과들을 종합해 볼 때, FGF - mediated FGFR signaling이 발육중인 두개골과 두개봉합부에서 세포의 증식과 분화의 균형을 조절하는데 중요한 담당하고 있음을 시사해주고 있으며, 이 과정중 FGF signaling이 osteopontin 및 Msxl 유전자의 발현을 조절하므로써 막내골 성장 및 두개봉합부의 유지기전에 기여할 것으로 사료된다. Craniosynostosis, the premature fusion of cranial sutures, presumably involves disturbance of the interactions between different tissues within the cranial sutures. Interestingly, point mutaions in the genes encoding for the fibroblast growth factor receptors(FGFRs), especially FGFR2, cause various types of human craniosynostosis syndromes. To elucidate the function of these genes in the early morphogenesis of mouse cranial sutures, we first analyzed by in situ hybridization the expression of FGFR2(BEX) and osteopontin, an early marker of osteogenic differentiation, in the sagittal suture of calvaria during embryonic (E15-E18) and postnatal stage (P1 - P3). FGFR2(BEK) was intensely expressed in the osteogenic fronts, whose cells undergo differentiation into osteoprogenitor cells that ultimately lay down the bone matrix. Osteopontin was expressed throughout the parietal bones excluding the osteogenic fronts, the periphery of the parietal bones. To further examine the role of FGF-mediated FGFR signaling in cranial suture, we did in vitro experiments in E15.5 mouse calvarial explants. Interestingly, implantation of FGF2 soaked beads onto both the osteogenic fronts and mid-mesenchyme of sagittal suture after 36 hours organ culture resulted in the increase of the tissue thickness and cell number around FGF2 beads, moreover FGF4-soaked beads implanted onto the osteogenic fronts stimulated suture closure due to an accelerated bone growth, compared to FGF4 beads placed onto mid-mesenchyme of sagittal suture and BSA control beads. In addition FGF2 induced the ectopic expression of osteopontin and Msxl genes. Taken together, these data indicate that FGF-mediated FGFR signaling has a important role in regulating the cranial bone growth and maintenance of cranial suture, and suggest that FGF-mediated FGFR signaling is involved in regulating the balance between the cell proliferation and differentiation through inducing the expression of osteopontin and Msxl genes.

This study analyzes the diagram of final concept, in order to establish a master plan for preparing a natural learning and experimental area in Bukchun and its surroundings, Gyeongju. The results could be summarized as follows. The stream of Bockan is the origin of Hyungsan River and it originates in the mountains of Banwon at 800m's length around Ulsan, Gyeongnam. It joins the streams of Choongli and Meonggae, and flows into Hyungsan river, passing through Gyeongju city, Naenam myon, Chunbook myon and Gangdong myon. The length of the river is extended to 62.2 km and to 11,166.80 ㎢ in area. Hyungsan river contains an important water resource for water supply, industrial service water, and agricultural service water for Gyeongju and Pohang city, but unsuitable polluted influents of water supply are due to contaminated increasing materials. The polluted stream normally dries out because of the lack of several side-streams, as a result of insufficient water during the dry season. All of the streams that flow into the East sea also suffer from lack of water, as the slope of those riverbeds is very severe, and the river rapidly drains out into the bay of Young-il. Bukchun showed that the speed of a funning fluid is very fast on a period of flood, but very slow in a period of water shortage about 0.02 m/s. This study is to investigate the its preservation method and suwater supply with ecology preservation and natural practical area in Buckhun. Also, it studies the agricultural service, and preservation water supply of Gyeongju. It was also investigated based on the diagram of final concept and master plan with culture environmental and natural practical area in Buckhun region.

「윤선옥전」에 나타난 전란 피해 형상화의 특징과 그 의미

최수현 이화어문학회 2021 이화어문논집 Vol.54 No.-

이 글은 「윤선옥전」이 전란의 피해를 형상화한 방식과 그 의미를 살펴본 것이다. 현재 유일본인 김광순본 「윤선옥전」은 윤선옥의 일대기를 다루나, 그 내용은 윤선옥이 천정배필인 박소저와 혼인하는 것과 전란으로 인해 헤어졌다가 재회하는 것이 주를 이룬다. 이 글에서는 그 중 전란이 개인에게 준 상처 측면에 초점을 맞춰 이 작품을 읽어보고자 하였다. 「윤선옥전」은 함경북도 종성을 윤선옥의 고향이자 전란의 피해 지역으로 설정하고, 윤선옥의 부친이 전란을 평정한 후 본거지를 타지로 옮기는 모습을 보여준다. 이는 고향을 떠날 수밖에 없던 사람들의 모습을 보여주었다는 점과, 전란의 위협에 노출되어 있던 관북지역 모습을 소설에서 보여주었다는 점에서 의미가 있다. 또 「윤선옥전」은 가문의 대를 이어야 한다는 명분 아래 부부가 피난길에서 헤어지는 모습을 보여준다. 이로 인해 홀로 남겨진 부인이 실절의 위기 속에서 자결하는 모습과 홀로 도망간 남편이 이 선택에 대해 끊임없이 괴로워하는 모습을 그려낸다. 이는 전란과 가부장제 이데올로기 아래 이중으로 고통 받는 부부의 모습을 보여주었다는 점에서 의미가 있다. 또한 「윤선옥전」은 전란으로 헤어진 자녀와 부모가 서로에 대한 그리움으로 고통받는 모습을 반복적으로 보여줌으로써 전란이 개인의 삶에 가져온 상처를 핍진하게 드러낸다. 동시에 이 같은 가족에 대한 그리움을 초월적 존재의 도움과 함께 가족의 재회를 완성하게 하는 동인이 되게 함으로써 가족애를 부각하고 있다. 이처럼 「윤선옥전」은 전란이 개인에게 가져다 준 횡포와 고통에 대한 문학적 상상력을 확인할 수 있게 한다는 데 의미가 있다. This article examines the method and meaning of “Yoonseonokjeon” that embodies the damage of war. The main contents are about the process where Yoon Seon-ok gets married to Park's woman and meets Park's woman again after splitting due to war. Therefore, this article tried to read this work focusing on the wounds that the war inflicted on individuals. “Yoonseonokjeon” sets Jongseong, an area in North Hamgyeong Province affected by the war, as the hometown of Yun Seon-ok. It shows Yoon Seon-ok's father moving his stronghold to another place after pacifying the war. This is meaningful in that it shows the suffering of those who had no choice but to turn their backs on their hometown, and it shows that the Gwanbuk region was exposed to the threat of war. Also, “Yoonseonokjeon” shows the couple breaking up on the way to escape under the pretext of passing on the family line. It portrays a wife who is left alone on her own, committing suicide in the midst of loss, and her husband, who runs away alone, constantly blaming himself for this choice. This is meaningful in that it shows the image of a woman and man who go through double suffering due to the war and patriarchal ideology. In addition, “Yoonseonokjeon” reveals the scars that the war has brought to an individual's life by repeatedly showing the children and their parents who have been separated by the war, longing for each other. At the same time, family love is emphasized by making this longing for the family a driving force to complete a family reunion with the help of a transcendent existence.

In this paper, we present a polarizer that consists of three step rotary detents which can selectively convert linear polarization into circular polarization and vice versa. For the design of the polarizer. the transmission line theory is applied to design the waveguide mode transducer for the modes to be smoothly converted between rectangular and circular waveguide. A dielectric plate is inserted i n circular waveguide for the conversion of a polarized wave with the angle of an inserted dielectric plate. Also. we simulated to obtain the optimum values of the transmission and the reflection coefficient characteristics at input and output port.

출혈성 수두는 심각한 합병증을 초래 할 수 있으며 사망률이 높은 질환으로 국내에서는 소아에서 발생한 2예 이외에는 성인에서 발생이 보고된 바가 없다. 본 증례에서와 같이 면역이 억제된 성인에서 출혈성 수포가 전신적으로 발생하면서 폐렴이 동반된 경우 치명적이므로 조기에 acyclovir 지속 정주요법 등의 적극적인 치료를 고려해야 한다. 저자들은 면역이 저하된 성인에서 폐렴이 동반된 출혈성 수두가 발생하여 조기에 acyclovir 지속적 정맥 주입요법 시행 후 치명적인 합병증 없이 호전을 보인 예를 경험했기 에 보고하는 바이다. Chickenpox is a common benign childhood disease caused by varicella-zoster virus, typically associated with fever and a characteristic exanthematous vesicular rash. The clinical manifestations in adults are more severe and more commonly complicated with varicella pneumonia. Hemorrhagic varicella, also called malignant chickenpox, is very rare and potentially fatal. Bleeding can occur in the form of hemorrhages within the rash and surrounding skin or within the mucous membrane. We report a case of hemorrhagic varicella complicated with pneumonia in a immunocompromised host. We emphasize on the successful treatment with continuous acyclovir infusion.

손수경,이지현 韓國學校保健學會 2002 韓國學校保健學會誌 Vol.15 No.1

This study was aimed at identifying on the state and knowledge toward smoking and passive smoking in middle school students. The data were collected from 6th. to 18th. August, 2001. Subject were 125 middle school students who were participated in the Smoking Cessation Program of S Health Agency in Busan. The collected data were analyzed by SPSS program for frequency, percent, mean, and chi-square test. The smoking related state and attitude of subjects were as follows; the number of the smoking students are 10(8.0 %) at present, 19(15.2 %) at past experience, 53(42.4 %) having at present smoking friends, 73(58.4 %) having at present smoking family. Also the smoking starting time of present or past smoking experience was the middle school; 12(9.6 %) and elementary school; 11(8.8 %). They started because of the peer group members; 12(9.6 %), curiosity; 8(6.4 %), and looking good; 7(5.6 %). The passive smoking related state and attitude of subjects were as follows; the number of the passive smoking aware rates are very well level; 71(56.8 %), well level; 54(43.2 %). The exposed experience to passive smoking was always; 38(30.4 %), sometimes; 86(68.8 %), not experience; 1(0.8 5). The place of exposure to passive smoking was game rooms; 67(53.6 %), house; 30(24.0 %), fast food place or cafeteria; 10(8.0 %), and street or in a vehicle ; 3(2.4 %). The main smoker to passive smoking exposure was unknown person; 61(48.8 %). grand parents or parents; 43(34.4 %), brothers or friends; 8(6.4 %), teachers; 4(3.2 %). The chief complant of passive smoking exposure was dyspnea; 36(28.8 %), coughing; 34(27.2 5), dizziness; 21(16.8 %), no symptom; 18(14.4 %). The mostly affected smoker to passive smoking exposure was parents; 52(41.6 %), brothers or friends; 48(38.4 %). The health affected perception to passive smoking exposure was very affected; 109(87.2 %), not affected; 3(2.4 %). In conclusion, it can be well recognized that considerable number of middle school students is exposed to the passive smoking in their homes and by unknown persons, but, their knowledge and attitude toward the exposure to passive smoking is not effective. Therefore, it is hoped that regular smoking education program at school and restriction campaign in home and the public place is necessary.

The purpose of this study was to evaluate the attitudes of parents toward behavior management techniques used in pediatric dentistry. These techniques were tell-show-do, voice control, HOM, active restraint by dental personnel, passive restraint by Papoose Board, premedication, N₂O-O₂relative analgesia, and general anesthesia, Seventy-six parents of very uncooperative children under 6 ages were selected who visited Department of Pediatric Dentistry of Seoul National University Hospital. The subjects were asked to indicate their degree of acceptability before and after viewing a scrapbook which provided explanations of these techniques. The following results were obtained: 1. There were significant differences in parental acceptability according to each behavior management technicque(p<0.01). 2. Psychological or physical methods were more acceptable than pharmacological techniques(p<0.01). The most acceptable method was tell-show-do, and the least one was general anesthesia. 3. Statistically significant differences in acceptability with prior explanations were seen in all methods except tell-show-do and physical restraint by dental personnel(p<0.01). 4. Girls´parents were significantly more accepting for tell-show-do after explanation than boys', and mothers were more accepting for physical restraint by dental personnel and Papoose Board before explanation than fathers, and middle school graduated parents were more accepting for premedication after explanation than college graduated parents(p<0.05).

외과적 노축과 교정력에 의한 매복 상악 견치의 치험례

정수연,한세현 大韓小兒齒科學會 1993 大韓小兒齒科學會誌 Vol.20 No.2

Each patient with an impacted maxillary canine must undergo a comprehensive evaulation of the malocclusion. There are several methods to treat impacted canine. Surgical exposure of the canine and orthodontic treatment to bring the tooth into the line of occlusion is considered the most desirable approach. Conservative exposure, light movement, and light force will minimize the undesirable effects such as devitalization, ankylosis, root resorption, gingival recession, and alveolar bone loss. Three cases are repoted, which were treated with surgical intervention and orthodontic tooth movement.
