Background: Our objective was to evaluate the accuracy of cardiovascular disease (CVD) risk score classification by direct LDL cholesterol (dLDL-C), calculated LDL cholesterol (cLDL-C), and non–HDL cholesterol (non–HDL-C) compared to classification by reference measurement procedures (RMPs) performed at the CDC. Methods: Weexamined 175 individuals, including 138 with CVD or conditions that may affect LDL-C measurement. dLDL-C measurements were performed using Denka, Kyowa, Sekisui, Serotec, Sysmex, UMA, and Wako reagents. cLDL-C was calculated by the Friedewald equation, using each manufacturer’s direct HDL-C assay measurements, and total cholesterol and triglyceride measurements by Roche and Siemens (Advia) assays,respectively. Results: For participants with triglycerides <2.26 mmol/L (<200 mg/dL), the overall misclassification rate for the CVD risk score ranged from 5% to 17% for cLDL-C methods and 8% to 26% for dLDL-C methods when compared to the RMP. Only Wako dLDL-C had fewer misclassifications than its corresponding cLDL-C method (8% vs 17%; P <0.05). Non–HDL-C assays misclassified fewer patients than dLDL-C for 4 of 8 methods (P <0.05). For participants with triglycerides ≥2.26 mmol/L (≥200 mg/dL) and <4.52 mmol/L (<400 mg/dL), dLDL-C methods, in general, performed better than cLDL-C methods, and non–HDL-C methods showed better correspondence to the RMP for CVD risk score than either dLDL-C or cLDL-C methods. Conclusions: Except for hypertriglyceridemic individuals, 7 of 8 dLDL-C methods failed to show improved CVD risk score classification over the corresponding cLDL-C methods. Non–HDL-C showed overall the best concordance with the RMP for CVD risk score classification of both normal and hypertriglyceridemic individuals.

Conduits for Coronary Bypass: Arteries Other Than the Internal Thoracic Artery’s

Hendrick B Barner 대한흉부외과학회 2013 Journal of Chest Surgery (J Chest Surg) Vol.46 No.3

This is the third in a series on coronary artery bypass which reviews three alternative arterial conduits. The radial artery has become the most widely used of the three and accumulating experience demonstrates better patency at 10 years versus saphenous vein. Drawbacks are a long incision on the forearm, the propensity for spasm and persistent sensory disturbance in about 10%. The first is answered by endoscopic harvest which may yield a shorter conduit but reduces sensory nerve injury. Spasm is managed pharmacologically and by less harvest trauma. The gastroepiploic artery is used in situ and free and although the abdominal cavity is entered complications are minimal and patency compares favorably with the radial artery. Use of the inferior epigastric artery remains minimal and its similar length often requires composite use but limited patency data are supportive. Other arteries have had rare use and this is unlikely to change because the three presented here have significant advantages and acceptance.

Conduits for Coronary Bypass: Internal Thoracic Artery

Hendrick B Barner 대한흉부외과학회 2012 Journal of Chest Surgery (J Chest Surg) Vol.45 No.6

This second report in the series on coronary artery bypass presents the authors experience and personal views on the internal thoracic artery (ITA) which date to 1966. There has been a very gradual evolution in the acceptance of this conduit which was initially compared with the saphenous vein and viewed as an improbable alternative to it. As is common with concepts and techniques which are ‘outside the box’ there was skepticism and criticism of this new conduit which was more difficult and time consuming to harvest for the surgeon who had to do it all. It was viewed as small, fragile, spastic and its flow capacity was questioned. Only a few surgeons employed it because of these issues and some of them would frequently graft it to the diagonal artery as it was thought not to supply adequate flow for the left anterior descending unless it was small. After a decade, angiographic data revealed superior patency to vein grafts. Even this evidence and survival benefit reported a few years later did not convince many surgeons that their concerns about limitations justified its use. Thus widespread adaption of the ITA as the conduit of choice for the anterior descending required another decade and bilateral use is only now expanding to more than 5% of patients in the US and somewhat faster in other countries.

Conduits for Coronary Bypass: Vein Grafts

Hendrick B Barner,Emily A Farkas 대한흉부외과학회 2012 Journal of Chest Surgery (J Chest Surg) Vol.45 No.5

The saphenous vein has been the principal conduit for coronary bypass grafting from the beginning, circa 1970. This report briefly traces this history and concomitantly presents one surgeons experience and personal views on use of the vein graft. As such it is not exhaustive but meant to be practical with a modest number of references. The focus is that of providing guidance and perspective which may be at variance with that of others and recognizing that there may be many ways to accomplish the task at hand. Hopefully the surgeon in training/early career may find this instructive on the journey to surgical maturity.

통일사상의 이상사회에 있어서 평등과 질서

hendricks, Tyler O. 선문대학교 통일사상연구원 1996 통일사상 연구논총 Vol.1 No.-

이 논문은 '역사와 사회'의 범주에 속하며 통일사상의 윤리론과 관련된다. 이 논문에서 필자는 정부 형성과 사회 본질에 적용되는 통일사상의 사회윤리 이론을 발전시키기 위해 노력하겠다. 이 논문에서 다루고자 하는 문제는 올바른 사회의 성격 확립에 관한 것이다. 이 물음에 대한 대답은 '선' 이라는 정의와 직접적으로 관련되어 있다. 한편, '선' 이라는 말은 평등이라고 정의되어도 무방하다. 반면, 그것은 '질서'라는 말로 정의되어도 좋을 듯 하다. 현대의 민주주의는 궁극적 가치로서 평등을 우위에 논고 있으며 전통적 군주주의는 질서에 보다 높은 비중을 두고 있다. 질서에 관해서, 고정적, 위계의 엄격성과 관계성, 그리고 부수적 역할을 하는 상호 의무 등을 살펴 보고자 한다. 통상적으로 질서는 그것의 유지를 위해 강력한 권위를 필요로 하지만, 권위를 가진 사람들에 의해서 남용되기도 해서 결과적으로 계급적 계층과 사회가 정체되는 결과를 낳는다. 가장 잘못된 경우의 결과가 전체주의이며, 널리 보급된 부당행위이다. 전통적 의미에 있어서 평등이란 사회를 평준화하는 것, 계층구조와 권위를 감소하는 것을 의미한다. 평등은 개인들 간에 있어서 상호권리와 특권이 동일하다는 것을 보여줌으로써 급기야 권위와 사회의 위계를 붕괴해 버린다. 여기에서 최악의 경우는 혼란과 무법천지 등을 불러 일으키는 질서와 안정된 관계 및 역할 등의 전체적인 해체이다. 군주주의는 평등을 희생시켜서 질서있는 사회를 확립했다. 민주주의는 평등을 허용하기는 하지만 질서를 유지할 수는 없다. This paper deals with an image sensor system and its position estimation algorithm for autonomous duct cleaning and inspection mobile robots. For the real application, a hierarchical control structure that consists of robot motion controller and image sensor system is designed considering the efficient and autonomous motion behaviors in narrow space such as air ducts. The sensor system consists of a CCD camera and two laser sources to generate slit beams. The image of the structured lights is used for calculating the geometric parameters of the air ducts which are usually designed with a rectangular section. With the acquired 3D information about the environment, the mobile robot with two differential driving wheels is able to autonomously navigates along the duct path without any human intervention. For real time navigation, the relative position estimation of the robot are performed from 3D image reconstructed by the sensor system. The calibration and image processing methods used for the sensor system are presented with the experimental data. The experimental results show the possibility of the sensor based navigation which is important for effective duct cleaning by small mobile robots.

Conduits for Coronary Bypass: Strategies

Hendrick B Barner 대한흉부외과학회 2013 Journal of Chest Surgery (J Chest Surg) Vol.46 No.5

Strategic planning is integral to any operation but complexity varies immensely and therefore the effort necessary to create the optimal plan. The previous three reports have discussed individual conduits and herein is an attempt to present approaches to common situations which the author favors. Although much has been learned over 45years about use and subsequent behavior of venous and arterial grafts we continue to learn and, as a result, evolve new strategies or modify those now popular. Thus the reader must recognize that in spite of trying to be balanced and inclusive all surgeons have personal opinions and also prejudices which influence the approach taken and which may not be the optimal one for others or for the patient.

A True Family Values Head-Wing Strategy for Korean Unification

Tyler Hendricks 선문대학교 통일사상연구원 2022 The Journal of Unification Thought Vol.2 No.-

Unification Thought teaches that peace results from give and take action for the purpose of goodness. The true family values inherent in Unification Thought and Head-Wing Thought, which refer to the practice of sexual abstinence before marriage and absolute fidelity in marriage, serve as a common base for such give and take action. I will discuss how this optimizes human happiness, and how the violation of these values leads to the collapse of the individual, family and nation. I will examine the decline of the adherence to these values in North Korea and South Korea, and discuss prospects for their revival. I conclude with a recommendation that the Universal Peace Foundation call representatives of nations—most importantly North and South Korea—to have give and take action with these Head-Wing values as a common base.

Background: Cassava and corn milling is a growing small-scale enterprise in Africa. We aimed todetermine the incidence of handearm musculoskeletal complaints among vibration-exposed Congolesecassava and corn millers in the previous 12 months. Methods: A cross-sectional study was conducted, prior to a follow-up study, from March to May2013 among cassava/corn millers in Lubumbashi, Democratic Republic of Congo, in which 365 millersage-matched to 365 civil workers anonymously answered a questionnaire. Results: Overall incidence of handearm musculoskeletal complaints was 25.8% in millers (vs. 5.2% in civilworkers; p < 0.001). The risk of experiencing musculoskeletal symptoms was seven times higher inmillers [vs. civil workers; odds ratio (OR) ¼ 7.10; 95% confidence interval (CI): 4.03e12.50; p < 0.0001];2.4 times higher in smoking millers (vs. smoking civil office workers; OR ¼ 2.36; 95% CI: 1.42e3.88;p < 0.001); 3.6 times higher in millers with longer daily exposure (> 8 hours; vs. those working ? 8hours; OR ¼ 3.56; 95% CI: 1.93e3.61; p ¼ 0.026); and 7.4 times higher in young millers (vs. older millers,OR ¼ 7.39; 95% CI: 1.29e75.52; p < 0.001). Smoking, number of cigarettes, and daily exposure durationwere positively correlated with musculoskeletal complaints. Conclusion: This study revealed a relatively high incidence of musculoskeletal complaints among Africancassava and corn millers. The use of anti-vibration protective equipment and the regulation of thishazardous occupation may reduce the burden of musculoskeletal disorders in millers.
