Objective : World Health Organization and International Labour Organization, in June 8, 1999, requested that working conditions should be reformed ethically right and economically solid for 2.7 billion world labour force. The purpose of this study is to request compensable surgical therapeutic options and to suggest the renewal in cognizance criteria for worker's compensation, especially in spondylolisthesis. Methods : Regarding spondylolisthesis, we obtained data from Korea Labor Welfare Corporation(KLWC). Spinal disease occurrence incidences and medical fees of National Federation of Medical Insurance(NFMI) were analysed. The compensated 122 spinal instrumented cases included 117 male and 5 female patients, aged from 23 to 72 years old(mean : $45{\pm}9.85$). We compared Korean and Foreign Workers Compensation Law. Results : Numbers of herniated nucleus pulpus(78 cases), spinal fractures(34 cases) and dislocations(4 cases) were claimed after spinal interbody fusion operation and were compensated. These compensated degenerative diseases, work related illness, occurred in the course of work. A case of 52-year old spondylolisthesis patient with Disability Grade 8 was compensated by KLWC, according to its occurrence at work by accident. With exception of trauma at work by accident, current cognizance criteria were too narrow to be compensable, especially in surgical therapeutic option, for worker's spondylolisthesis. Conclusion : Considering both worker's compensation law and clinical pathologic progress, we believe that spondylolisthesis should be regarded as a compensable occupation related disease if and when aggravates rapidly in the course of work. We suggest a new cognizance standard to KLWC for labour welfare and proper worker's compensation.

A time-dependent large deformation fracture theory is developed for application to soft biological tissues. The theory uses the quasilinear viscoelastic theory of Fung, and particularizes it to constitutive assumptions on polyvinyl-chloride (PVC) (Part I) and cartilage (Part II). This constitutive theory is used in a general viscoelastic theory by Christensen and Naghdi and an energy balance to develop an expression for the fracture toughness of the materials. Experimental methods are developed for measuring the required constitutive parameters and fracture data for the materials. Elastic stress and reduced relaxation functions were determined using tensile and shear tests at high loading rates with rise times of 25-30 msec, and test times of 150 sec. The developed method was validated, using an engineering material, PVC to separate the error in the testing method from the inherent variation of the biological tissues. It was found that the the proposed constitutive modeling can predict the nonlinear stress-strain and the time-dependent behavior of the material. As an approximation method, a pseudo-elastic theory using the J-integral concept, assuming that the material is a time-independent large deformation elastic material, was also developed and compared with the time-dependent fracture theory. For PVC. the predicted fracture toughness is $1.2{\pm}0.41$ and $1.5{\pm}0.23\;kN/m$ for the time-dependent theory and the pseudo-elastic theory, respectively. The methods should be of value in quantifying fracture properties of soft biological tissues. In Part II, an application of the developed method to a biological soft tissue was made by using bovine humeral articular cartilage.

내용어 기반 빈도 분석은 의도적 기만이나 반어적 표현에 분명한 한계가 있지만, 많이 사용되는 한국어 분석 프로그램인 KLIWC는 기능어 분석을, KrKwic는 동시출현빈도를 시각화하는 방법으로 발전했다. 하지만 개발된 지 십수 년이 지나 여러 문제점으로 개선이 필요한 상황이다. 그래서 KLIWC와 KrKwic를 분석하여 새 심리학적 언어분석 프로그램을 개발하고자 하였다. 첫째로 두 프로그램의 특징을 분석하였다. 특히, 기능어 분석기능 제고를 위해서 KLIWC와 한국어 형태소 분석기의 형태소 분류를 비교하였고, 심리적 분석의 강화를 위해 심리사전의 구조와 체계를 분석하였다. 분석 결과 한나눔 품사 분석기가 가장 세분화되었지만, 인칭대명사에서는 KLIWC가, 어미와 어말어미에서는 KKMA의 품사 분류가 더 세분화되어 있어, 기능어 분석 강화를 위해 여러 품사 분석기의 통합적 사용을 제안하였다. 둘째로 이 프로그램들로 텍스트를 분석한 연구들의 연구동향을 분석하였다. 분석 결과 두 프로그램이 복합학 분야 등 다양한 학술분야에서 사용되고 있었다. 특히 논문과 보고서의 분석에는 KrKwic가 많이 사용되었고, 글쓴이의 생각, 정서, 성격 비교 연구에는 KLIWC가 많이 사용되었다. 이 결과를 바탕으로 새로운 심리학적 언어분석 프로그램의 필요성과 개발 방향에 대해 제언하였다.
