Reciprocal effects among local breeds and additive and heterosis effects were estimated for total milk production per lactation (TLP), lactation length (LL) and daily milk yield (DMY). Procedures for an optimum crossbreeding system were examined by comparing various crossbred combinations. Three data sets were chosen from the total records collected from 1962 to 1997. Data set I with a total of 5,938 records composed of 9 breed groups for reciprocal crosses, data set II with a total of 6,064 records composed of 5 breed groups for additive and heterosis effects and data set III with a total of 10,319 records composed of 42 breed groups for optimum crossbreeding system were analyzed. The least squares ANOVA was used. The reciprocal crosses between Red Sindhi and the Bangladeshi Local showed significant difference. When the Red Sindhi was used as cow, the cross was superior to the opposite in terms of the three performance traits. The results showed that additive breed effects on both TLP and DMY were positive and highly significant between Bos indicus and Bos taurus, whereas the individual heterosis effects were not significant. In general, any local breeds were improved two to three times by crossing with the Friesian once or twice. However, the effect was reduced when the grading up with the Friesian was repeated more than twice. On the other hand, when the local breed was crossed with the other breeds such as Holstein and Jersey, the improvement of TLP was less. Crossing the F1 cows with the Friesian bull gave further improvement. Almost the same trends were found also for LL and DMY. The local breeds and their crosses are raised mainly for draft animals, then it is recommended that the crossbreds between the local cows and Friesian are used for dairy purposes and more than 75% Friesian blood is used for beef.

The paper aims to analyze and predict sales of liquor in the state of Iowa by applying machine learning algorithms to models built for prediction. We have taken recourse of Azure ML and Spark ML for our predictive analysis, which is legacy machine learning (ML) systems and Big Data ML, respectively. We have worked on the Iowa liquor sales dataset comprising of records from 2012 to 2019 in 24 columns and approximately 1.8 million rows. We have concluded by comparing the models with different algorithms applied and their accuracy in predicting the sales using both Azure ML and Spark ML. We find that the Linear Regression model has the highest precision and Decision Forest Regression has the fastest computing time with the sample data set using the legacy Azure ML systems. Decision Tree Regression model in Spark ML has the highest accuracy with the quickest computing time for the entire data set using the Big Data Spark systems.

Located in the southwestern part of Korea, the Yong San Gang river flows generally northeast to southwest, and because of the specific location, topography and climate, the basin area is subject to recurrent drought and flood damages. To eliminate the cause of such damages and ensure an increase in the farm income by means of effective irrigation supply and increased cropping intensity, efforts are being made to speed up implementation of an integrated agricultural development project which would include construction. of an estuary dam and irrigation facilities as well as land development and tidal reclarnation. In formulating a basin development project plan, it is necessary to study a series of long-term runoff data. The catchment area at the proposed estuary damsite is 3,471$\textrm{km}^2$ with the total length of the river channel up to this point reaching 138km. An analysis of runoff in this area was carried out. Rainfall was estimated by the Thiessen Network based on records available from 15 of the rainfall observation stations within the area. Out of the 15 stations, Kwang Ju and Mok Po stations were keeping long-term precipitation records exceeding some 60 years while the others were in possession of only 5-10 years records. The long-term records kept by those stations located in the center of the basin were used as base records and records kept by the remaining stations were supplemented using the coefficient of correlation between the records kept by the base stations and the remainder. The analyses indicate that the average annual rainfall measured at Kwang Ju during 1940-1972 (33 years) amounts to 1,262mm and the areal rainfall amounts to 1,236mm. For the purpose of runoff analysis, 7 observatories, were set up in the middle and lower reaches of the river and periodic measurements made by these stations permitted analysis of water levels and river flows. In particular, the long-term data available from Na Ju station significantly contributed to the analysis. The analysis, made by 4-stage Tank method, shows that the average annual runoff during 1940-1972 amounts to 2,189 million ㎥ at the runoff rate of 51%. As for the amount of monthly runoff, the maximum is 484.2 million ㎥ in July while the minimum is 48.3 million ㎥ in January.

본 고에서는 전자인사관시스템 데이터세트의 관리기준표 작성 절차와 방법, 참여 기관의 역할, 관리기준표 영역별 작성 내용 등을 기록관담당자 입장에서 분석하여 관리기준표를 수립해야하는 업무담당자의 이해를 돕고, 기준표 작성 과정 중에 나타난 문제점을 바탕으로 개선방안을 제시하였다. 주요 개선방안으로, 국가적 중요 행정정보 데이터세트에 대해서는 영구기록물관리기관 차원의 별도 선별 정책이 마련되어야 하고 일부가 아닌 전체 데이터세트를 보존하는 방식으로 운영되어야 하겠다. 또 단위기능 설정과 데이터 분석을 위해 단위기능-데이터테이블-비정형데이터 매핑 자료를 필수작성사항으로 설정할 필요가 있으며 시스템 운영에 큰 영향을 미치는 비정형데이터에 대한 선별, 관리기준이 추가로 작성되어야 하겠다. 처분지연기간을 설정하는 것은 보존기간의 복잡성을 증가시키는 측면이 있으므로 관련 단위기능의 통합 또는 보존기간 상향 책정 등의 방식으로 운영하는 것이 바람직할 것으로 판단된다.

This paper is to examine the bibliographical description of the revolutionary historical archives and the standardization of the archives management in China. The standardization in the field of records and archives management was not initiated on its own way but as a part of national - leveled standardization. As a first step National Committee on Technical Standardization of Literature was established, followed by the establishing of Committee on Technical Standardization of Micro - filming and Committee of Technical Standardization of Paper Form. The standardization of the records and archives management was carried out in the context of functions of these three committees. In 1983 the standardization in the sphere of records and archives management speeded up, when the National Archives Administration formed small organizations which led the standardization work all over the country. A committee of standardization originated from small organizations and it brought a great progress of the standardization. If some opinions on standardization were submitted from records offices or related offices, they were examined by the committee of standardization. The opinions that were submitted by the committee of standardization were examined by the National Archives Administration which proclaimed it officially. The Chinese government commenced to establish the bibliographical data centre for historical archives and materials on the basis of this process of standardization. In the case of the revolutionary historical archives the description was made on the level of sources(provenance), which was sent to the bibliographical data centre for historical archives and materials. The Chinese government set digitalizing as a goal in records and archives management in the middle of 1990's. It was regulated that the description of records item that should be transferred to the center must be digitalized. However, the description of the file level was not made separately being reflected in the process of description of item level. (The second part of the paper will be released in the next volume).

Angus postweaning daily gain (PWDG) were analyzed to investigate heterogeneous variance by sex. A set of data (16,239 records) was divided into six sub-data sets according to level of environment. REML estimation was conducted by a multitrait model, where PWDG in each sex was treated as a separate trait. Estimates showed diversity among environmental levels, where the heritability for heifers was high in good environment but low in poor environment. The bull's estimates varied among environmental levels. The largest heterogeneity of phenotypic variance between sexes was estimated in a data set of the poor environment level. The genetic correlations between the heifer's PWDG and the bull's PWDG were high in the good environment and low in the poor environment (-0.17). The results suggest existence of genotype by sex interaction in the poor environment.
