In this study, algorithms for analyzing the torsion of buildings under earthquake excitation are developed. The algorithm and formulations to account for the torsional angle are verified by analyzing the seismic acceleration time history data. The method was applied to the reference buildings to examine their operation and usability. The reference application demonstrated that the noise-canceling scheme successfully overcame various obstacles in the field measurements. The developed method is expected to be used as a tool to support a loss assessment system for determining the direction and priority of disaster response in the event of an earthquake.

시대적으로 바라본 마음과 몸의 수사학 : (편)두통의 사례

정성훈,Jeong, Seong Hoon 한국정신신체의학회 2014 정신신체의학 Vol.22 No.2

마음과 몸의 관계는 오랜 논의에도 불구하고 설득력 있는 답을 구하지 못하고 있다. 한편, 서구 의학이 유물론적 패러다임을 받아들이면서, 기질적 이상이 없는 증상들은 "의학적으로 설명되지 않는 증상"이라 하여 변방에 머물게 된다. 이러한 증상을 이해하고자 전문가들은 마음과 몸의 관계를 바탕으로 소위 정신신체의학이라는 해석의 틀을 내놓았다. 이 해석의 틀은 의사소통 방식뿐 아니라, 환자들의 건강추구 행위 및 증상을 경험하는 양식도 변화시켰다. 시대의 필요나 새로운 과학발견에 의해 해석의 틀은 변화되어 왔으며, 어떤 때는 마음이 어떤 때는 몸이 강조되었다. 특히 치료법이 부재할 때에는 마음이 강조되면서 환자의 인격이 비난 받거나, 환자의 책임이 더 강조되었다. 반면 약물치료가 등장한 후에는 마음을 강조할 필요성이 줄어들면서 환자의 책임 역시 면제되었다. 본 논고에서는 마음과 몸의 관계를 중심으로 해석의 틀이 어떻게 시대에 따라 변화했는지를, 두통과 편두통의 사례를 통해 살펴보고자 한다. 이를 통해 해석의 틀이 어떻게 증상을 경험하는 양상을 변화시켰으며, 그때마다 책임 소재가 어떻게 달라졌는지 고찰할 것이다. 이러한 통시적 고찰은, 전문가로 하여금 그들이 만들어내는 해석의 틀이 얼마나 큰 영향력을 가지는 지, 그것이 얼마나 시대 상황과 밀접한 관계를 맺는지를 고찰할 기회를 마련할 것이다. The relationship of mind and body has stimulated extensive discussion for a long time. However, answers are ambigous and not forthcoming yet. Meanwhile, after the western medicine had embraced materialistic paradigm, conditions which cannot be substantiated by organic change were pushed out to periphery under the banner of "Medically Unexplained Symptoms". Medical experts endeavored to understand these mysterious illnesses based on the mind-body relationship and provided a frame of interpretation called Psychosomatic Medicine. This frame of interpretation had influenced not only the communication practice but also the health-seeking behavior and even the subjective experience of patients regarding their illnesses. The frame of interpretation had been drastically changed many times keeping pace with the socio-economic situation and the new scientific discoveries. Accordingly, body or mind was given differential importance by medical experts. For instance, when treatment modalities were lacking, mind was given excessive importance and patients were blamed for their unconscious motives, characterological weaknesses and for their lack of responsibility. In contrast, after the discovery of effective drug, mind was given no more attention and patients were no longer blamed for their contribution to suffering. In this paper, the historical change of the frame of interpretation for understanding migraine and headache was presented as an example. By this, it can be demonstrated how the frame of interpretation has modified the subjective experience of patients, and how the patients' responsibilities were viewed differently. This observation can help to realize the enormous influence of the frame of interpretation provided by medical experts.

In this study, a structural health monitoring system for cable-stayed bridges is developed. In the system, condition assessment of the structure is performed based on measured records from seismic accelerometers. Response indices are defined to monitor structural safety and serviceability and derived from the measured acceleration data. The derivation process of the indices is structured to follow the transformation from the raw data to the outcome. The process includes noise filtering, baseline correction, numerical integration, and calculation of relative differences. The system is packed as a condition assessment program, which consists of four major processes of the structural health evaluation: (i) format conversion of the raw data, (ii) noise filtering, (iii) generation of response indices, and (iv) condition evaluation. An example set of limit states is presented to evaluate the structural condition of the test-bed and cable-stayed bridge.

■Background Overall prevalence of visual field loss after stroke was estimated at 31%, ranged from 5.5- 57%. Among them, homonymous hemianopia is the most common symptom of post-stroke visual field loss and leads to a decrease in the quality of life and therapeutic effect. However, standard treatment has not been established. ■Case report A 48-year-old male with right side homonymous hemianopia by a left occipital-parietal lobe hemorrhage was treated with Qu-Ji-Du-Huang-Wan, acupuncture and electroacupuncture for 20 days. We used confrontation visual field exam, automated perimetry and visual analog scale for evaluating symptoms. Following treatment, confrontation visual field exam and the subjective discomfort was improved. ■Conclusions The present case report suggests that combined Korean medicine treatment might be an effective treatment of post-stroke homonymous hemianopia. A number of follow up studies should be conducted to clarify the effectiveness of treatment.

Objectives:Nicotine addiction is regarded as the primary obstacle to ending cigarette smoking. Given this perspective, low-nicotine cigarettes were developed and marketed by tobacco industries as a healthier substitute for regular or full-flavor cigarettes. Many smokers believe that these low-nicotine cigarettes reduce cravings and withdrawal and thus help in the process of quitting smoking. However, this belief has not been substantiated by solid evidence. We tested the hypothesis that long-term low-nicotine cigarette smoking reduces cravings for cigarettes during the acute abstinence period. Methods:Fifteen male participants were divided into two groups based on their favorite cigarettes during the past year:low-nicotine cigarettes (10 subjects) and regular cigarettes (5 subjects). All the participants gathered and stayed together in a comfortable place for the entire study period. They were instructed to abstain from smoking from 4:00 pm to 10:00 am the next day (18 hours in total). The degree of craving during that time was repeatedly measured by the Visual Analog Scale and Tobacco Craving Questionnaire. The temporal change patterns of cravings were compared between the two groups. Results:The degree of craving continuously increased during the entire abstinence period. The temporal change patterns were much similar between the two groups. No statistically significant difference between the two groups could be fo-und in any of the measurements except the baseline VAS score. We could not find any evidence that low-nicotine smoking helped to reduce craving. Conclusion:Low-nicotine cigarettes currently marketed in Korea have no benefit in terms of reducing cravings during the acute abstinence period. Full-scale study over-coming the several limitations of this study with sufficient sample size would give sufficient counter-evidence to dispel the common myth that low-nicotine cigarettes are rational alternative to stopping smoking.

지역경제와 지방공기업의 재정건전화 방안

21세기는 세계적으로 무한 경쟁이 더욱 가속화 될 것으로 전망되어, 우리나라도 선진국형 국가 구조 틀(Frame)로 서둘러 변화해야 한다. 여기서 선진국형 구조 틀이란 지방분권화를 말한다. 즉 대부분 선진국들의 국가구조 틀은 중앙집권화가 아닌 지방분권화인 세계화와 지방화로 맞춰져 있다. 지방정부는 자본과 기술, 인력을 유치하여 세계시장에서 치열한 경쟁을 통해 지역 발전을 해야 함에도 불구하고, 행정, 제정 권한 등 여러 측면에서 국가 운영과 지방자치가 여전히 중앙집권적으로 이루어지고 있어 지방과 수도권의 경제양극화가 심화되고 있다. 이렇다 보니, 국가의 모든 국책사업(관광, 개발 등)이 중앙정부 및 공공기관 위주로 사업을 하여, 경제적으로 열악한 지방정부 및 공공기관은 사업성과 상관없이 중앙정부에 가능한 한 많은 재원과 사업을 요구하게 되고, 이로 인해 지방발전 사업의 대부분은 악화되어 지방재정에 부정적인 영향을 미치는 악순환이 되풀이되고 있다. 이에 반해 무분별하고 과도한 중앙집권 사업으로 인한 거대 부실 중앙 공공기관이 늘어나 국가부채(광의의 개념으로 공기업도 포함)를 증가시켜, 현재 GDP대비 대략 80%수준까지 올라 향후 국가경제가 매우 우려되는 수준이다. 이러한 문제를 해결하기 위해서는 지자체로 사업권한과 책임을 대폭 이양하는 정책을 시급히 추진해야 한다. Much so, the country’s national projects (tourism, development, etc.), the business to focus on the central government and public institutions, and the economically disadvantaged local government and public agencies, regardless of profitability and funding as much as possible to the central government and the business needs to As a result, the majority of the rural development projects, and have a negative effect on the local finances are worse and the vicious cycle of recurring. In contrast, the giant insolvent central public institutions increased business due to the indiscriminate and excessive centralization by increasing the national debt, the broader concept of public enterprises (included), a percentage of GDP, roughly 80% up to the level of the national economy in the future is very concerned about the level at which. Business transfer of authority and responsibility greatly policies to local governments in order to solve these problems urgently be pursued.
