  • The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. A collection of 965 black soybean lines currently grown by farmers was made in 197 locations on spring, 1991. This study was carried out to evaluate them as useful germplasm. Seed characteristics of black soybean collections were evaluated for black soybean breeding for seed quality. The 100-seeds weight of 929 black soybean genotypes were distributed from 6.9 to 48.1 gram. The maximum and minimum 100-seeds weight were derived from Chungnam and Jeonbuk province, respectively. l00-seeds weight was heavier in middle and late maturity group, as maturity was later, whereas no tendency was shown in early maturity group. Length, width and thickness of the collected black soybean seeds were 9.5$\pm$1.5mm, 7.3$\pm1.3mm and 7.3$\pm1.2mm, respectively. Black soybean collections with yellow seed embryo was 72% and the others were green seed embryo.

  • A Ypsolophid moth Saridoscelis sphenias Meyrick was recorded in 2020 first in Korea, and specimens were collected from Jindo and Wando in Jeonam province from 2016 to 2017. This moth uses host plants such as Pieris japonica (Thunb.) D. Don ex G. Don, Vaccinium bracteatum Thunb. and Leucothoe grayana Maxim. var oblongifolia (Miq.). This species was discovered once in a blueberry orchard in Jeju in August 2014, and since then it has been regarded as not an established species because of no further detection. However, S. sphenias was found again in blueberry orchards grown in vinyl houses in Jeju city and Seogwipo city in 2018 and 2019. Since 2020, this pest has also been found on field-grown blueberries. Hatched larvae first bored into new shoots and fed inside, and the mid-aged larvae escaped from the inside of shoots, attached several shoots with webs, and fed on the leaves in the group. It is considered that S. sphenias will become a severe pest on blueberries; thus, we report the basic life cycle here.

  • Recently, research on behavior analysis tracking human posture and movement has been actively conducted. In particular, OpenPose, an open-source software developed by CMU in 2017, is a representative method for estimating human appearance and behavior. OpenPose can detect and estimate various body parts of a person, such as height, face, and hands in real-time, making it applicable to various fields such as smart healthcare, exercise training, security systems, and medical fields. In this paper, we propose a method for classifying four exercise movements - Squat, Walk, Wave, and Fall-down - which are most commonly performed by users in the gym, using OpenPose-based deep learning models, DNN and CNN. The training data is collected by capturing the user's movements through recorded videos and real-time camera captures. The collected dataset undergoes preprocessing using OpenPose. The preprocessed dataset is then used to train the proposed DNN and CNN models for exercise movement classification. The performance errors of the proposed models are evaluated using MSE, RMSE, and MAE. The performance evaluation results showed that the proposed DNN model outperformed the proposed CNN model.

  • Collected 38 colored soybeans, which was cultivated under the conventional field conditions, were investigated about their organeloptic parameters and correlations among factors such as organeloptic score, texturometer parameters and chemical components of seeds. Most of the organeloptic parameters were affect much more by the characteristics of each cultivars than by grain weight, and then showed significant differences with the effect of interactinon between grain weight and cultivar, too. Also among contribution degrees of texturometer scores to overall acceptance, cohesiveness was higher in small, medium and super grains, however in large grains, hardness. And among sensory attributes, suitable toughness was contribute most positively to acceptance.

  • Consolidation settlements on marine dredged clays are often greatly and potentially damaging to structures. Currently, large-scale projects are in planning or progressing in Korea. These projects have been performed on thick and soft clay layers. So, the evaluation of consolidation characteristics for dredged and reclaimed ground is very important in design and construction. Therefore, in this study, a series of conventional consolidation tests were performed to investigate the consolidation characteristics of marine dredged clays near Gwang-yang Port. Preconsolidation pressures were evaluated by applying previously proposed 8 methods for the conventional tests results in order to evaluate the legitimacy of these methods. In these methods, when estimating maximum past pressures for dredged and reclaimed ground, it was proved that Becker (1987), Silva (1970), Sridharan (1991)'s methods are excellent in legitimacy.

  • The employees in social welfare institutions have an importance of learning due to jop specialty more than any one else. That is because there are a variety of increasing needs in social welfare services and customer-oriented welfare services. On the basis of that, this study shows how learning orientation theories as a new organization management strategy affects the employees in social welfare institutions. It shows cause and effect relation by establishing hypothesis model based on the preceding researches. It performed empirical analysis on the employees in social welfare institutions in G metropolitan city. As a result, the hypothesis was tested that learning flow, vision sharing, openness have significant effects on member's jop satisfaction. It implies that job satisfaction can be improved, if the level of learning flow, vision sharing, openness of the employees in social welfare institutions are promoted.

  • The Economic Gab-Jil, where the stronger are forcing the weaker to sacrifice, is not only a serious social problem, but also it exhausts the vitality of the national economy. Especially, the issue of 'cost reduction (CR) of delivery price' in automobile industry, and the issue of 'tolls' and 'retaliating' in the franchise business are becoming more controversial. This paper suggests some measures to rectify the problems by an analysis using a game-theoretic model. One of the ways to change the 'bad equilibrium', where economic Gab-Jil is prevalent, to the 'good equiblium' is to strengthen the bargaining power of the weak by legal and institutional measures. It is also a more market-friendly system that is self-enforcing, where the regulation is automatically enforced by the incentives of the participants, without relying solely on the enforcement power of regulatory or supervisory bodies

  • The purpose of this paper is to examine the structural change of Korean manufacturing industries and the differences of total factor productivity(TFP) between exporting industries and import substituting industries in Korean manufacturing industry from 1980 to 2013. The empirical results show that over half of total 13 industries have experienced changes of direction from import to export or export to import, which implies that there was a considerable structural change in Korean manufacturing industry. The output growth rates are higher in exporting industries than in import substituting industries. All industries employ more capital than labor during the period, which means that production methodology in Korean industries changes to a more capital intensive one. Finally, the growth rate of total factor productivity is higher in exporting industries than in import substituting industries, and it is also proved in panel regression analysis.
