주상골 골절에서 Herbert/Whipple 나사못의 바람직한 위치 : 모형연구 A Model Study
유재두,김종오,윤여헌,고영도,배서영,이정준 대한골절학회 2002 대한골절학회지 Vol.15 No.4
목 적 : 주상골 골절 치료에 사용하는 Herbert/Whipple 나사못의 바람직한 삽입 위치를 알아보고자 하였다. 대상 및 방법 : 4개의 사체에서 분리한 주상골을 이용하여 각 주상골마다 12개씩 주물 모형을 제작하여 대상으로 하였다. 각 모형에서 핀 삽입 안내 장치(jig, Zimmer??)를 이용하여 안내핀(guide wire)을 원위부에서 근위부를 향해 삽입하되 원위부에 A, B, C, D의 4개 근위부에 0, 5, 10의 3개의 지점을 설정하여 총 12가지 방법으로 삽입하였다. 각 모형은 주상골의 장축에 직각인 방향으로 근위부, 요부, 원위부의 세 단면을 만들고 핀 삽입의 흔적과 가장 가까운 피질골 표면과의 거리를 측정하여 이 거리가 대적으로 길 때 안전한 것으로 평가 하였다. 결 과 : 핀 삽입의 흔적과 가장 가까운 표면과의 거리가 근위부에서는 D5, 원위부에서는 C10이 유의하게 길었다. 원위 삽입 위치를 기준으로 하였을 때 근위부에서 C가 유의하게 거리가 길었고 요부, 원위부, 그리고 근위 목표 지점을 기준으로 하였을 때의 측정된 거리는 유의한 차이가 없었다. 결 론 : Herbert/Whipple 나사못의 삽입 위치는 근위부 골절에서는 D5군, 원위부 골절에서는 C5군이 가장 바람직한 위치라고 할 수 있엇고 요부 골절에서는 A0군과 D0군을 제외하면 별 다른 차이 없이 비교적 안전하다고 할 수 있다. 바람직한 위치 선정을 위해서는 근위부의 목표지점보다 원위부의 지점을 정확히 하는 것이 중요하다고 사료된다. Purpose : To evaluate optimal placement of the Herbert/Whipple screw in scaphoid fracture Materials and Methods: Forty eight model molded from four cadaver scaphoids were used for this study. Using the Herbert/Whipple jig, the guide wire was placed distal to proximal into each scaphoid with twelve method which were four entry points and three target points. Guide wire placement was then evaluated with three planes in the proximal, middle, distal planes and distance from the nearest cortex. Results : The most concentric position in the proximal plane was D5, in the middle plane C10. As distal entry point, the most concentric position in proximal plane was C. There were no statistical concentric, as middle, distal plane, and proximal entry point, Conclusion : The most ideal placement were D5 in proximal fractures of the scaphoid, C5 in distal fractures. In waist fractures of the scaphoid, there were relatively safe, except A0 and D0. The position of entry points was more important than that of target points for ideal screw placement.

The purpose of this study was to get the quantitative data of effect of two different load carrying system on Kinematics and Kinetics. The subjects for the research were 2-adults. The mechanism of each load carrying pattern was measured by a motion analyzer a forceplatform and E.M.G system. The conclusion were as follow from Kinematics Variable's and Kinetics Variables. 1. It was not effected at the vertical reaction force(Fz) of left, right foot according to the big value of the 1st peack of 10kg, 15kg fore, back-pack carrying system, 20kg, 30kg back-pack carrying system in walking. But, it was effected at the vertical reaction force(Fz) on 30kg back-pack carrying system in walking. 2. It was not effected at the Anterior-Posterior reaction force(Fx) of left, right foot according to high value of the 1st peack on 10kg, 15kg fore, back-pack carrying in walking. But, it was effected on the 20kg, 30kg only back-pack carrying system in walking. 3. It was effected at the legt-right reaction force(Fy) of left-right foot according to the big value of the 2nd peak on 10kg, 15kg fore-backpack carrying system in walking. It was more effective than 20kg, 30kg back-pack carrying system in walking. There was not disorder force(Fx) on 10kg, 15kg fore-backpack carrying system in walking. 4. Analysis of computer graphic, on the pack carrying system in walking. It was efficient in 10kg, 15kg fore-backpack carrying system in walking. But, it was not efficient on 20kg, 30kg backpack carrying in walking. Castrocnemius, Tibialis anterior, Vastus lateralis, Vastus medialis, are stressed to bend their body foreward. So it should be occurred fatigue fastly, injured muscles and joints. 5. Extension analyses and flection angles of the Knee joint and the hip joint on 10kg, 15kg fore-backpack carrying system in walking showed less than on 20kg, 30kg backpack carrying system in walking. It was efficient on the 10kg, 15kg fore-backpack carrying system in walking.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>Previous studies showed that the insulin resistance (IR) could be related to depression. However, this association is still equivocal in the general population. Herein, we aimed to investigate the association between IR and depressive symptoms in a large sample in South Korea.</P> <P><B>Methods</B></P> <P>A cross-sectional study was carried out for 165,443 Korean men and women who received a health checkup including various clinical parameters and the Center for Epidemiologic Studies Depression scales (CES-D). Subjects were stratified into subgroups by CES-D score, sex, age, and presence of diabetes.

Subgroup analysis revealed this association was statistically significant in females (adjusted OR=1.03, [95% CI 1.001–1.06]), non-diabetic group (adjusted OR=1.04, [95% CI 1.02–1.06]), and young participants under the age of thirty (adjusted OR=1.17, [95% CI 1.07–1.27]).

Existential Issues and Psychosocial Interventions in Palliative Care
Lee, Jae-Hon Korean Society for Hospice and Palliative Care 2020 한국호스피스.완화의료학회지 Vol.23 No.4
The finite nature of human existence leads many to search for meaning, which comes into sharper relief for those who are imminently facing death. Therefore, universal existential concerns such as the inevitability of death, existential isolation, loss of meaning, freedom, and dignity are inherent psychological issues in palliative care. Consequently, one of the critical challenges facing palliative care is how to address these issues effectively. This paper provides an overview of common themes of existential concerns and psychotherapeutic interventions to address existential distress among patients in palliative care.
