While there is a rapid transition to smart work due to COVID-19, not many studies have measured the changes in organizational culture after firm-wide institutionalization of smart work. Through a questionnaire and a series of stakeholder interviews, this study examined how and to what extent employees' perception of organizational culture changed after the introduction of smart work in a large leisure service company H in South Korea. The working culture of the organization is measured as the changes in the organizational members' perception on seven dimensions: strategic innovativeness, organizational flexibility, fair human resource management, rational decision making processes, organizational vitality, trustful collaboration, proactive leadership. The results demonstrated that, after the introduction of smart work, the organizational members' perception on strategic innovativeness, organizational flexibility, organizational vitality, trustful collaboration have declined significantly while the changes in fair human resource management, rational decision making processes, and proactive leadership are insignificant. Though found to be insignificant, follow up interviews revealed that participants think that the role of management leadership is very critical for the smart work systems to be institutionalized successfully. While the smart work may have different effects depending upon industry or organizational characteristics, this study present a case for changes in organizational culture after institutionalizing smart work. Implications are discussed with further research issues at the end.

The glutathione (GSH) concentration in leaves of different maturities and roots of forage rape (Brassica napus L.) supplied with four levels of external $SO_4^{2-}$ (0, 0.1, 1.0 and 2.0 mM) supply were measured. The relationships of GSH concentration with $SO_4^{2-}$ uptake, ATP sulfurylase (ATPS) and O-acteylserine (thiol) lyase (OASTL) activity were also assessed. The $SO_4^{2-}$ uptake increased in parallel with the external $SO_4^{2-}$ supply, while protein concentration was not significantly changed. The ATPS activity increased continuously with decreasing $SO_4^{2-}$ supply from 2.0 to 0 mM, while the OASTL activity decreased significantly only at S-deficient conditions (0 and 0.1 mM). The GSH concentration in the young leaves, middle leaves and roots continuously increased (except for between 1.0 and 2.0 mM in the middle leaves and roots) as the external S supply was increased, but no significant changes occurred in the old leaves. The increased endogenous GSH concentration, affected by the $SO_4^{2-}$ supply level, was significantly related with the decrease in ATPS activity in both leaves and roots, and the decrease in OASTL activity only in leaves..

Experiments on the physiological root activity and its related characteristics of rice varieties were carried out in order to obtain some basic informations for the application of the results obtained to a rice breeding program. A significant positive correlation was found not only among the various characteristics related to conducting and ventilating systems which connects top and root of rice plant, but also between these characteristics and root activity. On the other hand, a significant difference in physiological root activity was recognized among different varieties and also between different groups of recognized 7 rice varieties differing in the their origin. It was also found that varieties with higher root activity (root activity indices) after ear formation stage tended to have more number of lower green leaves and consequently resulted in higher grain yield. Therefore, it may be possible to diagnose indirectly the root activity by examining the number of green leaves of the rice plant at later growth stage when breeders make selections of parent material for crossing or of hybrid lines in pedigree nurseries.

An experiment with alfalfa (Medicago sativa L.) plants was designed to investigate the changes in non-structural carbohydrate (NSC) contents and the activities of amylolytic enzymes during a regrowth period following defoliation. Sampling from hydroponic grown-plants were carried out at intervals during 24 days of regrowth. Shoot regrowth was very slow during the first 10 days and root growth was depressed after defoliation. Defoliation induced a great decrease in both total sugar and starch contents in taproots during the first 10∼14 days. A major recovery of NSC occurred from day 15. Averaged over sampling dates, the activity of exo-amylase was about 400-fold higher than that of endo-amylase. Exo-amylase activity in defoliate plants slightly increased until day 6 (maximum level) and then decreased. Endo-amylase rapidly increased for the first 4 days after defoliation and slightly increased afterwards to a maximum on day 24. These results showed that increase in amylolytic enzyme activity in taproots coincided with the time of starch utilization during regrowth and that indicated it plays an important role in starch degradation.

This study was performed to elucidate the effects of copper poisoning on the reproductive organ of rats. After consecutive oral administrations of copper sulfate, the weights of testis, the numbers and motilities of sperms, organ weights and histological changes of testes were compared between control and experimental groups. 1. Testis weights of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administrated rats gradually decreased compared with control group, and the values no significant changes. 2. The sperm numbers of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administrated rats were lowered in dose dependent manners than those of control group's and the values no significant changes. 3, The motilities sperms of 1,000, 2,000 or 4:000 ppm/kg of copper sulfate-administrated rats decreased significantly in dose-dependent manners compared with those of control group's. 4. The weights of livers and kidneys of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administration rats decreased or increased. 5. Necrosis of hepatocytes around the central veins and infiltrations of fine granules-harboring macrophages in periportal and interstitial tissues were found out in the livers of copper sulfate-administrated rats. The Bowman's capsule and tubules of kidneys were filled with hyaline material.

This study was performed to elucidate the effects of lead poisoning on the reproductive organ of rats. After consecutive oral administrations of lead acetate, the weights of testis, the numbers and motilities of sperms and histological changes of organs were compared between control and experimental groups. 1.

Anatomical and biochemical changes of the corn root injured by the root lesion nematode, Pratylenchus vulnus, were examined to understand the interactions between the nematode and the crop which can be applied to a breeding program for nematode-resistant crop. The nematode and the crop which can be applied to be a breeding program for nematode-resistant crop. The nematode entered the cortex of corn root through its epidemis. They moved to other cortical cells by breaking their cell walls. They, finally, gathered around the endodermis of the roots and the bases of the root hairs. Parasitism of the nematode formed cavities within the root tissues where the females laid eggs. Major root damage by the nematode occurred in the cortical cells where must cell walls were broken and crushed to form empty spaces. These empty spaces in the base of the root resulted in this breakdown. Damage-induced biochemical changes of the corn roots were analysed by their total protein patterns and esterase activities in both control and nematode-infected roots. Denaturing gel did not show any significant difference in the banding patterns between them. Esterase patterns and activities, also, were not significantly different between the infected and the control roots.

The purpose of this study was to verify the relationship between job calling consciousness and job enthusiasm for the development of marine police izations and individuals. A study was conducted on 136 Korea Cost Guard officials. Sub-variables of vocational calling consciousness consisted of transcendent calling, the existence of purpose and meaning, and pro-social-oriented motivation, and job enthusiasm consisted of vitality, immersion, and dedication. As a result of the verification, it was found that transcendent calling, purpose, and meaning, which are sub-variables of occupational calling recognized by Korea Cost Guard officials, have a positive (+) effect on vitality, and commitment. However, it was found that pro-social-oriented motivation did not affect vitality, commitment, and immersion. Through the analysis results, practical implications of the maritime police ization were proposed.
