Station metadata for the 546 stations of the regional seismic networks being operated in the southern Korean Peninsula were integrated. The bibliographic and index data regarding the installations and change histories of seismic stations administered by Korea Meteorological Administration, Korea Institute of Geoscience and Mineral Resources, and Korea Institute of Nuclear Safety from their initial installation to July 2023 were collected through the responses in their instruments. The resulting station metadata were integrated into extensible markup language (XML) format for use in the ObsPy platform and into pole-zero (SACPZ) format for use in the Seismic Analysis Code software. These pieces of software are currently the most widely used for seismic waveform processing and analysis. The integrated station metadata was posted on a webpage to promote the transparency of seismic monitoring information, correct possible errors in the information collection process, and allow the consideration of some additional seismic station information in the future through feedback from individual analysts (https://geophysics.pknu.ac.kr/SeismicNetwork.html).

This study was carried out to estimate environmental effects such as calving season, calving year on peak milk yield, days in milk at peak production(PKD), drying-off milk yield on 305-day, 305D milk yield, and persistency. The data used in this study were milk yield records from first freshened Holstein cows(187 heads) bred in National Livestock Research Institute from 1990 to 1996. Calving season, sire and calving year didn't affect days in milk at peak(PKD). But peak milk yield(PKM) was significantly affected by calving season(p$lt;.01) and calving year(p$lt;.05). Calving season, sire and calving year significantly affected the drying-off milk yield at 305D(DRYM) related to persistency(p$lt;.05). The PKD was 58.2±23.2day, peak milk yield was 26.2±3.9㎏ and drying-off milk yield on 305-day was 15.7±3.5㎏. The persistency showed 60.3 13.8%, and the phenotypic correlations of persistency between PKD and DRYM was positive.
Holstein 종 젖소의 유기별 Somatic Cell Score 에 미치는 제 요인효과 추정

A total of 2,215 available records of 571 heads tested from 1997 to 2000 at National Livestock Research Institute(NLRI) were used to estimate environment and sire effects for somatic cell count(SCC) in different lactation period of Holstein cattle. The cows were fed according to NRC and managed by the method of NLRI. Milk yields were recorded twice a day with 12 hours interval and SCC transformed into SCS= log₂(SCC/100000)+3 was analysed by Milkoscan 4000^ⓡ for each month. A lactation was divided into the three periods which were early period(earlier than 90 days in milk), middle period(91 to 200 days in milk) and late period(later than 200 days in milky. The effects of milking year and month, parity, milking parlour style and sire for whole lactation period showed significant differences on SCS(P$lt;0.01). But the above factors on SCS showed different effects in accordance with the lactation periods. The somatic cell scores from January to July were lower than those from August to November. A minimum level of SCS showed at first parity and then increased. For style of milking parlour. SCS in the tandem style was lower than that in herringbone style.
