Asian Social Quality Indicators

LIH-RONG WANG 서울대학교 사회발전연구소 2009 Journal of Asian Sociology Vol.38 No.2

This paper discusses the paradigm diffusion of social quality from Europe to Asia and our research findings in relation to the four conditional factors of social quality (socio-economic security, social inclusion, social cohesion, and empowerment). The construction of Asian social quality (ASQ) indicators includes redefining Asian understanding of social quality and reaching a consensus to revise the indicators developed in Europe. The consensus was reached through meta-analysis and the Delphi approach. Study results reveal that the construction of ASQ indicators is not only the work of a collaborative, cross-national research team from South Korea, Hong Kong, Japan, Taiwan, and Thailand, it also constructs a new meaning, that is, economic growth is no longer the first and only priority of state and society in the greater Asian co-sphere, but rather, social quality now emerges as the key issue for concern among Asian citizens and academics. In the conclusion, some suggestions are presented on additional potential indicators that could be integrated into our current ASQ indicators as well as the uniqueness of constructing ASQ indicators.

Cell type-specific STAT3 activation by gp130-related cytokines in the peripheral nerves

Wang, Lih,Lee, Hyun Kyoung,Seo, In Ae,Shin, Yoon Kyung,Lee, Kyu Yeol,Park, Hwan Tae Lippincott Williams Wilkins, Inc. 2009 NEUROREPORT - Vol.20 No.7

Nerve injury-induced activation of signal transducer and activator of transcription 3 (STAT3) in sensory neurons and Schwann cells has been implicated in peripheral nerve regeneration. In this study, we investigated the role of gp130-related cytokines including interleukin-6 (IL-6), ciliary neurotrophic factor (CNTF), and leukemia inhibitory factor (LIF) in STAT3 activation in dorsal root ganglion neurons, Schwann cells, and endoneurial fibroblasts. We found that IL-6, but not CNTF or LIF, activated STAT3 in Schwann cells. However, CNTF and LIF, but not IL-6, activated STAT3 in dorsal root ganglion neurons. Furthermore, LIF was the primary activator of STAT3 in endoneurial fibroblasts. These findings indicate that gp130 cytokines may have cell type-specific roles in peripheral nerve regeneration.

Gender-role Attitudes and Women's Decision on Employment : An Example of Taiwan

Wang, Lih-Rong 숙명여자대학교 아세아여성문제연구소 2003 Asian Women Vol.16 No.-

This paper explores Taiwan women's gender-role attitudes and their impact on their decisions to join the labor force. The research was conducted by face-to-face interviews through structured questionnaires. 505 women in the north part of Taiwan were interviewed. The test of gender-role attitudes consisted of three measurements including: The appropriateness of employment in their child-bearing age. Women's attitudes toward men being the breadwinners, and women the homemakers. Women's attitudes toward gender role divisions in the family. The findings state women's decisions regarding employment are highly associated with women's gender role ideology, and the data further indicate that Taiwanese women still maintain strong traditional gender role perspectives, an attitude that maintains women's appropriate role is in the home, particularly for women who are at the age of child-bearing.

왕립 ( Lih Wang ),손성근 ( Sung Keun Shon ),이규열 ( Kyu Yeol Lee ),김철홍 ( Chul Hong Kim ),이명진 ( Myung Jin Lee ),이철원 ( Chul Won Lee ),김성수 ( Sung Soo Kim ) 대한골절학회 2008 대한골절학회지 Vol.21 No.2

목적: 대퇴골 전자간부 골절 치료에서 골절의 양상 및 안정성을 예측하기 위해 술 전 3차원 컴퓨터 단층촬영을 시행하여 불안정 골절에 대해 추가 분류하였고 후방 골편 고정의 중요성 및 중간 치료결과에 대해 보고하고자 한다. 대상 및 방법: 2006년 10월부터 2007년 8월까지 후방 골편이 있는 불안정 골절로 진단 받고 금속정을 이용하여 치료 한 후 최소 3개월 이상 추시가 가능하였던 15예를 대상으로 하였다. 5예에서 후방 골편에 대해 경피적 도관나사 고정술을 시행하였고 (실험군), 나머지 10예는 시행하지 않았다 (대조군). 술 후 추시 방사선 평가를 통해 수술 직후와 추시 대퇴 경간각의 변화, 골절부 감입 정도를 비교 평가하였으며 합병증을 조사하였다. 결과: 대퇴 경간각은 후방 골편 고정군에 있어서 평균 3.8도, 고정을 하지 않는 군에서는 평균 7.5도의 내반 변화를 보였다. 골절부 감입은 고정군에 있어서 평균 1.6 ㎜, 고정하지 않는 군에서는 평균 6.6 ㎜의 변화를 보였다. 합병증으로는 고정하지 않는 군에서는 경부나사의 전자부 외측 돌출, 지연나사의 관절 내 돌출 및 지나친 전위로 인한 Z-현상이 각각 1예가 있었다. 결론: 대퇴 전자간부 불안정 골절에 있어서 후방 골편의 인지 및 고정은 정복 소설을 막는 데에 있어서 중요한 요소라고 생각되나 보다 많은 증례 및 장기간 추시가 필요할 것으로 사료된다. Purpose: To predict the feature and stability of intertrochanteric fractures with posterior fragment using preoperative 3D computed tomography and to investigate the importance of the posterior fragment in treatment of unstable intertrochanteric fracture. Materials and Methods: 15 cases of unstable fractures with posterior fragment which were treated with nail only between October 2006 to August 2007 were classified into 2 groups: study group (5 cases with cannulated screw fixation of posterior fragment) and control group (10 cases without cannulated screw fixation). The average difference of neck-shaft angle, neck screw sliding distance and the complications in the two groups were compared retrospectively after a follow up of at least 3 months. Results: The average difference of neck-shaft angle in study and control group was 3.8 and 7.5 degree (p>0.05), respectively. The average difference of neck screw sliding distance was 1.6 and 6.6 ㎜ (p<0.05), respectively. Complication which required reoperation was not noted in study group and complications of 3 cases about neck screw lateral protrusion, proximal migration and Z-effect phenomenon were noted in control group. Conclusion: The recognition and fixation of the posterior wall was found to be an important predictive factor in unstable inter-trochanteric fracture treatment.

왕립(Lih Wang),김경택(Kyung Taek Kim),박원석(Won Seok Park),정성윤(Sung Yoon Jung),정영훈(Young Hun Jung) 대한정형외과학회 2016 대한정형외과학회지 Vol.51 No.4

슬와부 혈관 임박 파열과 동반된 대퇴골 cross-pin 파손은 전방십자인대 재건술 중 대퇴골 터널 형성 시 발생할 수 있는 매우 드문 합병증이다. 저자들은 1차 재건술 후 16일만에 cross-pin의 파손과 함께 슬와부 혈관의 임박 파열이 발생한 1예를 경험하였다. 슬와부 혈관 임박 파열은 cross-pin의 파손과 함께 초음파를 통해 진단되었으며 이는 슬와부의 불편함과 이물감을 유발하였다. Cross-pin과 기존의 전방십자인대 이식물 및 간섭 나사의 제거 및 새로운 이식물과 간섭 나사를 이용한 전방십자인대의 재건술 시행 후 환자는 만족스러운 결과와 증세의 호전을 보였다. 이에 저자들은 위 증례를 문헌 고찰과 함께 보고하고자 한다. Breakage of the femoral cross-pin with impending rupture of the popliteal vessels is a rare complication for femoral tunneling in anterior cruciate ligament (ACL) reconstruction. The authors experienced a case of impending rupture of the popliteal vessels following breakage of the cross-pin 16 days after primary ACL reconstruction. Impending rupture of the popliteal vessels was detected with ultrasonography following breakage of the cross-pins which caused popliteal discomfort and irritation. After removal of the broken cross-pins, previous ACL graft and interference screw with subsequent re-reconstruction of the ACL using a new allograft and interference screw, the patient showed satisfactory results and resolution of symptoms. Therefore we report on this case with a review of literature.

역행성 대퇴부 골수강 내 금속정을 이용한 슬관절 고정술 : 술기 보고

왕립(Lih Wang),김선효(Sun Hyo Kim) 대한정형외과학회 2021 대한정형외과학회지 Vol.56 No.2

슬관절 고정술은 슬관절이 손상되어 재건술을 시행할 수 없는 환자에서 안정적이고 통증이 없는 슬관절을 얻을 수 있는 마지막 선택사항 중 하나이다. 슬관절 고정술에는 외고정 장치, 압박 금속판을 이용한 내고정, 조립형 금속정 또는 이상와로부터 삽입하는 전향적 금속정을 이용한 내고정 등 다양한 방법들이 사용되어 왔다. 다른 선택사항으로 Neff 정, Wichita 정, 또는 Huckstep 정과 같은 짧은 금속정을 이용하기도 한다. 그러나 한국에서는 현재 사용 가능한 상용화된 짧은 금속정이 없다. 이에 저자들은 역행성 대퇴부 골수강 내 금속정을 이용한 슬관절 고정술을 보고하고자 한다. Arthrodesis is one of the last options available to obtain a stable, painless knee in patients who are unable to undergo reconstructive surgery due to a damaged knee joint. A variety of techniques have been used, including external fixation, internal fixation by compression plates, intramedullary fixation through the knee with a modular nail, and antegrade nailing through the piriformis fossa. Another option is the use of a short nail such as the Neff nail, the Wichita nail, or the Huckstep nail, but there are no commercial short nails available for use in Korea. This technical report describes a technique for knee arthrodesis using a retrograde femoral intramedullary nail.

목적: 슬관절 전치환술 후 발생한 대퇴골 삽입물 주위 골절에서 2가지 최소 침습적 술식에 따른 치료 결과를 비교하고자 한다. 대상 및 방법: 2005년 1월부터 2011년 1월까지 동아대학교의료원에서 슬관절 전치환술 후 발생한 대퇴골 삽입물 주위 골절 36예(남자 5명, 여자 31명)를 대상으로 하였다. 수술 당시 평균 연령은 68.9세(범위, 43-81세)였고, 평균 추시 기간은 41개월 (범위, 18-72개월)이었다. 전체 36예 중 잠김 금속판 고정술을 시행한 19예를 I군, 역행성 골수강 내 금속정 고정술을 시행한 17예를 II군으로 분류하였으며 두 군 간의 임상적, 방사선적 결과를 비교 분석하였다. 결과: 모든 환자에서 성공적인 골유합이 이루어졌고 평균 골유합 기간은 I군에서 3.7개월, II군에서 4.2개월이었다. 평균 수술 시간 및 평균 실혈량에 있어서 두 군 간의 유의한 차이는 보이지 않았다. 임상적 평가에 있어서 두 군 간의 유의한 차이는 없었으나 방사선적 평가에 있어서 II군에서 보다 외반 변형을 보였고 두 군 간의 유의한 차이를 보였다. 결론: 슬관절 전치환술 후 발생한 대퇴골 삽입물 주위 골절에 대한 2가지 최소 침습적 방법에 있어서 임상적으로 모두 좋은 결과를 얻을 수 있었으나 잠김 금속판 고정술이 방사선적 정렬에 있어서 보다 양호한 결과를 보였다. Purpose: The purpose of this study is to compare the treatment results of fracture fixations by using two minimal invasive techniques for patients with periprosthetic femoral fractures following total knee arthroplasty. Materials and Methods: We reviewed 36 patients (5 males, 31 females) of periprosthetic femoral fractures whom were treated surgically between January 2005 and January 2011. Mean patient age was 68.9 years (range, 43 to 81 years) old and the follow-up period averaged 41 months (range, 18 to 72 months). Nineteen patients were treated with minimal invasive locking plate fixations (group I) and 17 patients with retrograde intramedullary nailing (group II). Clinical and radiological outcomes in each group were comparatively analyzed. Results: Successful bone unions occurred in all patients and the mean time to bone union was 3.7 months in group I and 4.2 months in group II. There were no statistical differences between the two groups according to mean operative time and mean intraoperative blood loss. There were also no statistical differences between two groups according to clinical outcomes but the valgus deformity was apparent in group II and radiological outcomes revealed significant differences between the two groups. Conclusion: For the treatment of periprosthetic femoral fractures after total knee arthroplasty, two minimal invasive techniques have shown good clinical results. However, the minimal invasive plate fixation showed better results in the radiological alignments.

Neuroprotective Activity of Vitis thunbergii var. taiwaniana Extracts In Vitro and In Vivo

Chung-Kwe Wang,Lih-Geeng Chen,Chi-Luan Wen,Wen-Chi Hou,Ling-Fang Hung,Shish-Jung Yen,Yi-Jyun Shen,Shyr-Yi Lin,Yu-Chih Liang 한국식품영양과학회 2010 Journal of medicinal food Vol.13 No.1

Vitis thunbergii var. taiwaniana (VTT) is a wild grape native to Taiwan, where it has been used as a folk medicine. In this study, we found that the branch and leaf ethanol extracts of VTT significantly inhibited the inducible nitric oxide (NO) synthase protein expression and NO production in BV2 microglia. Using primary neuronal cells, kainic acid (KA) significantly increased hydrogen peroxide production in a dose-dependent manner. All four ethanol extracts of VTT significantly decreased hydrogen peroxide production. However, only root and branch ethanol extracts were able to prevent the neuronal cell death induced by KA in vitro. In the animal study, administration of all four plant part extracts of VTT delayed the onset of seizure and decreased the hippocampus neuronal cell loss, and the neuroprotective activity could be ranked as follows: branchleaf>root>trunk. The results suggest that VTT extracts have a potential to prevent neurodegeneration through the antioxidative activity by their ability to inhibit NO and hydrogen peroxide production.
