This paper investigated Taxi drivers physical subjective symptoms and what factors were interviewed caused the symptoms. The 600 owning taxi-drivers in Seoul during four months from August 1st, 2003 to November 30th, 2003. 1. The average age of the owning taxi-drivers was generally quite high 54 years old. It was very high index compared with the Todai Health Index(THI) and Cornell Medical Index(CMI) of health check tables. 2. According to the age in THI health check table, the complains of mental subjective symptom by reason of age was high among 31 to 40 years old. People who belonged that age group showed high fabrication(L), digestion(C) and aggressiveness(F). The results showed the complains of mental subjective symptom. All items except tiredness(I), melancholia(N), and hypersensitivity(P) were commonly reported by people in their sixties. On the other hand, melancholia(N) and hypersensitivity(P), people in their forties were investigated highly. Statistically, the items of heartㆍblood stream(C) and digestion(D) systems were similar between the two ages, but anger(Q) was different. (p<0.05) 3. From the complains of mental and physical subjective symptoms about work satisfaction on the THI health check table, all items except eyeㆍskin trouble(B) showed strong dissatisfaction. From the complains of mental and physical subjective symptoms about work satisfaction on the CMI health check table, the items of respiratory system(B), digestion(D), nervous system(G), miscellaneous(K), inadequancy(M), and anger(Q) showed similar results. Otherwise, heartㆍblood stream(C) showed statistically different. 4. From the complains of mental and physical subjective symptoms on salary satisfaction in the THI health check table, in the case of people receiving around 1 million won, the complains of physical symptoms showed high among all items except for the respiratory(A) and digestion(C) systems. The eyeㆍskin trouble(B) item showed statistical similarity. The complains of mental and physical subjective symptoms according to a salary degree on the CMI health check table was completely different from the above results. In people received around 1~1.5million won, all items except anxiety(O) showed high. The hypersensitivity(P) item showed statistically different.

This paper is concerned with the techniques of error check and reduction of state diagram using logic programming. Error check program aims to check not only syntax errors but also semantic errors. And reduction program optimizes the state diagram by finding the redundant equivalence states and removing those from the set of states. The input of both program is state diagram represented as state table form. The output of error check program is error comment. The output of reduction program is equivalence reduced state table. Both programs are implemented using prolog. Prolog has very powerful pattern matching, and its automatic back-tracking capabilities facilitate easy-to-write error check and reduction programs.

목적 : 근접치료에 사용하는 동위원소인 Ir-192는 전량 수입에 의존하고 있으며, 그 Activity는 Welltype Chamber를 이용하여 측정하거나 제조업체의 선원 강도 인증서를 믿고 의존하는 방법, 또는 Farmer Chamber를 이용한 in-air dosimetry 등이 있다. 본 논문에서는 좀더 간단하고 단순한 Farmer Chamber를 이용한 방법을 소개하고자 한다. 대상 및 방법 : Farmer Chamber와 Source Calibration jig를 이용하여 Ir-192 동위원소의 Activity를 측정하고 그 값을 제조사의 선원강도 인증서의 값과 비교하여 선원의 Activity를 check한다. 결과 : 측정결과 제조사의 값과 비교하여 ${\pm}2.1\%$로, AAPM 권고 값인 ${\pm}5\%$ 안의 오차범위에 들어가는 차이로서 임상에서의 사용이 가능하다. 결론 : 근접치료장치의 사용증가와 그에 따른 선원의 수입 증가는 불가결하다. 그리고 선원의 정확한 Activity Check는 필수이다. 선원의 Act check를 위해 Well type chamber의 추가 구입 없이 Farmer Chamber와 Source Calibration jig를 이용하여 정확한 선량 측정이 가능하였다.

Eum Sik Check is a cooking book written in old Korean by a woman called Dan Yang Daek. In this study, the contents of the book are interpreted in modern Korean, and are analyzed, compared, and examined in the point of view of cooking. The book shows 1) the methods of the setting of a large table, of a table for ancestor-memorial services, of decorative seasonings, 2) 11 methods for making rice cakes, 3) 21 methods for side dishes, and 4) 7 methods for berwing rice wine.

Table detection is a challenging problem and plays an important role in document layout analysis. In this paper, we propose an effective method to identify the table region from document images. First, the regions of interest (ROIs) are recognized as the table candidates. In each ROI, we locate text components and extract text blocks. After that, we check all text blocks to determine if they are arranged horizontally or vertically and compare the height of each text block with the average height. If the text blocks satisfy a series of rules, the ROI is regarded as a table. Experiments on the ICDAR 2013 dataset show that the results obtained are very encouraging. This proves the effectiveness and superiority of our proposed method.

An excitation table is commonly used for vibration and ride tests for parts or assemblies of automobiles, aircrafts, or other heavy systems. The authors have analyzed several kinematic properties of an excitation table that is under development for heavy transport vehicles. It consists of one table and 7 linear hydraulic actuators. The authors have performed mobility analysis, inverse kinematics, forward kinematics, and singularity analysis. Especially, we have proposed a fast forward kinematic solution considering the limited motion of the excitation table. On the assumption that the motion variables such as rotation angles and displacements are small, the forward kinematic problem is converted to the observer problem of a linear system. This provides a fast solution. Also we have verified that there are no singularity points in the working range by numerical analysis.

XML 전자상거래 분야 뿐만 아니라. 모든 학술분야와 산업분야에서 사용하고 있는 만큼, 표준화된 문서를 다루는 필수적인 기능을 가지고 있다. 또한 XML 자료를 관계형 데이터베이스 자료로 만들어 SQL 언어를 사용하여 자료 검색도 필요하다. XML과 관계 데이터베이스 간의 변환을 위해선 두 자료간의 매핑 관계가 필요하다. 그래서 본 논문에서는 문서 자체에서 항상 통일된 형식으로 문서를 작성하게 하고 문서를 읽을 때마다 이런 통일성을 자동적으로 검사하게 하는 DTD(Document Type Definition)를 사용해서 XML과 데이터베이스 간의 매핑 관계를 연구하고, 그 결과 XML Data를 Realation Database table로 매핑하는 매핑 설계도를 연구하였다.

단일프로세서 환경에서 주기 태스크의 시간 제약 조건을 만족시키면서 비주기 태스크의 평균 서비스 시간을 최소화하는 연구가 계속 진행되어 왔으나, 최근의 시스템은 여러 개의 프로세서를 병렬처리하여 프로그램의 처리속도 향상을 꾀하는 멀티프로세서 환경으로 전환되어 가는 추세다. 따라서, 멀티프로세서 환경에서의 태스크 스케쥴링에 관한 다양한 여구가 필요하게 되었다. 일반적으로 멀티프로세서 환경에서는 주기 태스크를 스케쥴링하기 위해서 RMFF(Rate-monotonic First-Fit) 스케쥴링 알고리즘을 사용하는데, 이 알고리즘에서는 비주기 태스크의 스케쥴링을 위한 알고리즘을 추가로 요구한다. 따라서, 본 논문에서는 멀티프로세서 환경에서 주기 태스크와 비주기 태스크가 혼합되어 있을 때, 기존의 RMFF 방식에 슬랙 체크테이블(Slack Check Table;SCT)을 이용하여 비주가 태스크를 효율적으로 스케쥴링하기 위한 방법을 제안한다.

Rockfall has long been a serious problem, especially derailment of train running on the track in mountainous regions. The purpose of this study is to suggest the reasonable items of check and evaluation to railroad rock slopes for safe maintenance and management of rockfall-worried railroad sites. Therefore, main and sub items were extracted from the survey of foreign and other authorities' cases and evaluation table (temporary) composed of items classified by important degree was suggested. To evaluate the availability and reasonability of items, statistical analysis based on field investigation namely SMR(Slope Mass Rating) and explanation values was carried.
