  • To evaluate direct and maternal effects on calf market weight (CMW) and carcass weight (CW) in Japanese Black cattle under an animal model, genetic parameters were estimated using 51,320 records of CMW and 11,944 records of CW, respectively. Direct and maternal heritabilities, and direct-maternal genetic correlation were estimated to be 0.22, 0.06 and 0.27 for CMW, and 0.23, 0.12 and -0.40 for CW, respectively. Correlation coefficient between maternal breeding values for CMW and CW was 0.521 for 157 sires appeared in both CMW and CW data sets. These results suggest that the maternal genetic effect on pre-weaning growth carries over to carcass weight. Maternal breeding values for both calf market weight and carcass weight could be used as the indicator traits of maternal ability in Japanese Black cattle.

  • Diet composition of amphibians usually reflects the distribution of potential prey within habitats, as well as their diet preference. We identified the diet items of Japanese tree frog (Hyla japonica) using a stomach flushing method in a rice paddy for the establishment of bio-monitoring systems of landscape changes. During the reproductive period, 71% of calling males had empty stomachs. All prey items in the stomachs belonged to the phylum Arthropoda, from eight orders of Insecta and one order of Arachnida. Among insect prey, the most common items in the stomachs were adults of beetles, flies and bugs, and larvae of butterflies and moths. There was a significant positive correlation between the body mass of Japanese tree frogs and the volume of prey items. Our results can provide a basic framework to guide the monitoring systems using prey identification of Japanese tree frogs.

  • The coronavirus disease 2019 (COVID-19) pandemic has led to a flood of research papers and the information has been updated with considerable frequency. For society to derive benefits from this research, it is necessary to promote sharing up-to-date knowledge from these papers. However, because most research papers are written in English, it is difficult for people who are not familiar with English medical terms to obtain knowledge from them. To facilitate sharing knowledge from COVID-19 papers written in English for Japanese speakers, we tried to construct a dictionary with an open license by assigning Japanese terms to MeSH unique identifiers (UIDs) annotated to words in the texts of COVID-19 papers. Using this dictionary, 98.99% of all occurrences of MeSH terms in COVID-19 papers were covered. We also created a curated version of the dictionary and uploaded it to Pub-Dictionary for wider use in the PubAnnotation system.

  • In Korea, countermeasures against earthquake disasters such as the seismic performance evaluation and/or retrofit scheme of buildings have not been fully performed since Korea had not been experienced many destructive earthquakes in the past. However, due to more than four hundred earthquakes with slight/medium intensity occurred in the off-coastal and inland of Korea during the past 20 years, and due to the great earthquakes occurred recently in neighboring countries, such as the 1995 Hyogoken-Nambu Earthquake with more than 6,500 fatalities in Japan and the 1999 Ji-Ji Earthquake with more than 2,500 fatalities in Taiwan, the importance of the future earthquake preparedness measures in Korea is highly recognized. The main objective of this paper is to provide the basic data for development of a methodology for the future earthquake preparedness in Korea by investigating the concept and applicabilities of the Japanese Standard for Evaluation of Seismic Performance of Existing RC Buildings developed in Japan among the methodologies of all over the world. In this paper, a seismic performance evaluation method of the existing reinforced concrete buildings is proposed based on experimental data of columns and walls carried out in Korea by referring the Japanese Standard, especially focusing on the Strength Index(C) among the indices in the seismic capacity index(IS) equations. Also, the seismic capacities of two existing reinforced concrete buildings in Korea are evaluated based on the proposed methodology and the Japanese Standard, and the correlations between the seismic capacities by the proposed methodology and the Japanese Standard are discussed.

  • Japanese anise (Illicium anisatum L.) twigs were collected and ground after drying, then immersed with 50% aqueous acetone for 3 days. After filtration, the extracts were fractionated with n-hexane, chloroform ($CHCl_3$), ethylacetate (EtOAc) and $H_2O$, and then freeze-dried after condensation. A portion of EtOAc soluble fraction (5.7 g) was chromatographed on a Sephadex LH-20 column with various aqueous $MeOH-H_2O$. Compound 2 and compound 3 were isolated from fraction 8 and 5, respectively. Compound 1 and compound 4 were isolated after rechromatography of fraction 7. The isolated compounds were elucidated as (+)-catechin (1), taxifolin (2), taxifolin-3-O-${\beta}$-D-(+)-xylopyranose (3) and quercitrin (4) by spectral and literature data, and by comparison with the authentic samples. Of the isolated compounds, taxifolin (2), taxifolin-3-O-${\beta}$-D-(+)-D-xylopyranose (3) and quercitrin (4) were isolated, for the first time, from the extracts of japanese anise twigs.

  • The Japanese "Just-In-Time" technique reduces inventory and unnecessary factors. This technique makes the success of Japanese firms, therefore many Korean firms try to apply it to their situation. But the technique doesn't bare the same success in Korean firms. This paper, therefore, considers the different situations between Korean rim and Japanese firm, then simulates the Pull system and Push system for a multiline, multistage production system. This paper drives the different results of simulation according to variable processing times, variable demand, set-up time and shortages in Pull system and Push system using GPSS. The results show that the performance of Pull system is lower than Push system's in variable master production scheduling and variable processing times.ing times.

  • This paper represents a partial outcome of a doctoral research undertaken at the University of Tokyo, Japan. The doctoral research looked on the phenomenology of innovation and its implications for the construction industry in Japan. This paper focuses on the perception of innovation by major Japanese construction clients and major Japanese construction firms. Among construction researchers innovation is a popular topic and no conference will miss covering the issue. After a period of very critical judgment on the ability of the construction sector to innovate and partially even frustration on the inflexibility of the sector, a much more positive attitude was taken. At present, most construction researchers would agree that the construction sector clearly is very innovative. That stands in contrast with how construction practitioners perceive their own sector. This paper presents the results of and empirical research in how construction clients and contractors in Japan perceive the issue of innovation. In fact the perceptions differ largely and give interesting insights on particularities of the Japanese construction sector and on the mismatch of clients and contractors perceptions.

  • TPM was introduced to industries of Korea in the middle of the 80's. Thereafter, the reorganization of Korean industrial structure brought out the spread of TPM activities. However, TPM activities in Korean industries seem to be inferior to those in Japanese industries. We think this situation has occurred, because many Korean industries have directly applied the TPM model developed by Japanese industries without adjustment. In this paper, based on consulting experience, we present a TPM model that is suitable to the culture of Korean industries and can be a means of improving a competitive power of company.
