본 보고는 1981년 국제견사협회가 불란서리온에서 개최되었을 때 제일차 보고를 기술연구분과위원회의에서 발표된 바 있는데 당시의 반응이 좋았었고 동시에 신규로 생사검사방법을 위임받은바 있는 스위스 측 대표로부터 제일차보고를 좀더 구체적으로 설명하여 달라는 요청을 받아 제이차 보고를 1982년 영국런던에서 개최된 바 있는 제15차 국제견사대회에서 재차 발표하게 되었다. 본 보고는 복잡을 피하기 위해 삼각법에 의한 이론전개 대신 XY축 직각좌표수식으로 이론을 전개하여 더욱 명확하게 이해 할 수 있도록 작성되었으며 스위스 대奈표도 이제는 확실히 알게되었다는 언급을 받게되었다. 한편 본 연구에 대한 고찰부문은 한국잠사학지 제22권 제2호 제22면을 참고하여주기 바란다. 본 연구에서 얻어진 요약은 다음과 같다. 1. 본 연구에서 생사검사결과와 그들로 만들어진 견직물 품위사이의 관계를 조사한 결과 타원형태의 이차곡선관계가 있음을 알았다. 2. 이러한 관계를 근거로 하여 생사검사등급간의 급간치를 검사항목별로 산출할 수 있는 표준벌점 parameter표를 작성하였으며 이것을 최병희 표준벌점 parameter라 명명하였고 다음과 같은 parameter가 작성 되였다. 3. 실제 생사검사 등급매기 표를 작성하는데는 다음과 같은 단계를 밟아서 이루어진다. (A) 가급적 많은 생사검사하구를 상대로 하여 E격부터 6A격에 이르기까지의 검사결과를 이용하여 각 검사항목별로 평균치와 표준편차를 정확하게 조사한다. (B) 각 검사항목에 대한 통계적 최대치와 최소치는 평균치에다 4배양의 표준편차 값을 가감하여 산출한다. (C) 각 검사항목에 대하여 통계적 개차(R)는 8배양의 표준편차로 하고 표준벌점의 산출에는 위에 제시한 parameter표 수치와 곱셈해서 얻는다. (R$\times$parameter) (D) 사조반 사조반열등 대중절 및 소절열등과 같이 백분율로 결과 표시되는 검사항목에 대하여는 최대치에서 표준벌점을 공제한 것으로 표시한다. (E) 생사섬도편차 및 최대편차와 같이 실벌점으로 표시되는 검사항목은 최소치에다 표준벌점을 가산해서 얻어진다. 4. 이상의 방법을 주요검사 항목에 한해서 반복함으로서 생사검사등급 매기표가 완성된다.

Standard industry and occupation code are usually assigned manually in Korean census. The manual coding is very labor intensive and expensive task. Furthermore, inconsistent coding is resulted from the ability of human experts and their working environments. This paper proposes an automatic code classification system which converts natural language responses on survey questionnaires into corresponding numeric codes by using manually constructed rule base and example-based machine learning. The system was trained with 400,000 records of which standard codes was assigned. It was evaluated with 10-fold cross validation and was tested with three code sets: population occupation set, industry set, and industry survey set. The proposed system showed 76.63%, 82.24 and 99.68% accuracy for each code set.

In this study, international standards in disaster management and the management of the relevant International Standards Organizations(ISO), in particular ISO / TC 292 (Security- Safety) research subcommittee to look at international standards of relevant international standards for disaster management trends, each international domestic law related to the standard were researched. National Disaster Management Authority as a Ministry of Public Safety and Security (formerly the National Emergency Management Agency) has continued to prepare a plan for applying national disaster management relevant to the international standards. As the disaster management international standard continues to be established, disaster management agencies need to continue to keep pace with the international community to find ways to introduce international standards.

Standard Penetration Test (SPT) and Cone Penetration Test (CPT) are widely used in geotechnical investigation methods for railway roadbed. However, SPT can not be used on the Railway track, since the equipment may contact to the electric lines. However, a portable equipment can be used for geotechnical investigation without electrical hazard. Dynamic Cone Penetrometer (DCP) is one of representative portable equipments. A normal portable DCP has usually not enough driving energy and the rigidity of cone-rod, so it is impossible to investigate the required investigate penetration depth. In this study, The adaptability of Pagani cone test which is one of portable dynamic cone penetrometer is studied and compared with SPT-N data. As a result of this study, the proposed correlation factors between Pagani cone test and SPT-N values after corrections is 1.48 for sandy soil and 1.33 for clayey soil.

Waste Stone and Waste Stone Powder are recycling some cyclic aggregate only. And the greater part of Waste Stone and Waste Stone Powder are reclaining or neglecting. To solve this problem, the government is proceeding development of cementitious scagliola using waste stone and waste stone powder. However, quality standard for cementitious scagliola using waste stone and waste stone powder has not been established. So cementitious scagliola using waste stone and waste stone powder has problem of quality assurance. Therefore in this study, developed standard for Evaluating Performance of cementitious scagliola using waste stone and waste stone powder through survey of international standard.

The constituents of sugar, enzyme activity and number of pollens in standard honey (gathered from my own honey comb.) and commercial ones collected from local markets) were determined to know the difference between above two kinds of honey. The results obtained were as follows. 1. The constitution of saccharides in commercial honey was higher at 1% than the standard one. The average content showed 45% of fructose,41% of glucose, 3% of dextrin and 2% of sucrose. 2. Pollen contained in honey were mainly composed of oval and globe shape. The nunlber of pollen contained in standard honey was five times more than that in commercial ones .3. ${\alpha}-amylase$, ${\beta}-amylase$ and protease activity of standard honey were greated 5,2,2 times respectively comparing with that of commercial one, and acid protease activity with each sample was higher than the neutral.

The present research has been carried out in an attempt to obtain fundamental data which contribute to enhansing the accuracy of cocoon reeling test and improving the method of it more effectively. The results obtained are as follows: 1. The standard deviation and coefficient of variation of percentage of reelability and of percentage of raw silk yield to the sample size tended to show a gradual decrease according to the increasing of the sample size. However, the significant differences in the standard deviation and coefficient of variation of percentage of reelability and of percentage of raw silk yield between the different sizes of the samples having more than 300 cocoons have not been observed according to their sizes. 2. The significant difference in the standard errors from percentage of reelability between the samples of 300 cocoons and 400 cocoons have not been observed. 3. The significant difference in the standad errors from percentage of raw silk yield between the samples of 300 cocoons, 500 cocoons and 600 cocoons have not been observed. 4. The significant difference in the standard deviation, the standard errors and coefficient of variation to the length of a bave between the different sizes of the samples have not been shown. 5. From the above result, it is estimated that the optimum sire of the sample for the cocoon reeling test is the 300 cocoons.

Mortality for oldest-old age (aged 80 or over) in Korea has never been studied mainly due to lack of data leaving its quality aside. The rapid aging recently occurring in Korea, which no other country has never experienced, must introduce a drastic change in the structure of future population pyramid, requring a careful investigation on mortality level, pattern, and trend for the oldest-old age in Korea. For mortality trend, we need to extend the past mortality data, which has provided only an open-ended age interval 80 or 85 years and over, to age-specific mortality up to 115 years old. A prerequisite for such an extension is constructing a Korean standard mortality by which one can figure out the mortality level and pattern of the oldest-old age. A Korean standard mortality is proposed by applying one relational model and eleven functions from which we select best models for each sex in terms of three measures of fits and three consistencies of mortality. Then we extend the mortality of the open-ended age intervals by providing a method to avoid the longitudinal consistency of mortality.
