Although several studies have been conducted on unification and the life of North Korean refugees, there have been few studies comparing the characteristics of North Korean refugees with South Korean workers, in terms of human resources in business administration. By considering the limitations of these prior studies, this study analyzed whether there are differences in factors affecting organizational commitment and turnover intention through a group comparative analysis between North Korean refugees and South Korean workers. For a comparative analysis between the two groups, we recruited 145 workers from North Korea and 213 South Korea-born workers. We found the following results with a multi-group structural equation model. We confirmed the measurement homogeneity by ensuring that both groups were equally aware of the measurement tools affecting organizational commitment and turnover intentions. As a result of testing the homogeneity of measurement, we also confirmed that there was a significant difference in optimism between the two groups; optimism affects organizational commitment and among social supports, affectionate support and interaction support affect organizational commitment. Analyzing the path between the two groups, we first were able to find that optimism influenced organizational commitment for both groups, in relation to positive psychological capital. However, in terms of degree, South Korean workers were found to be strongly affected. Second, with regard to social support, we were not able to find that affectionate support and interaction support have a significant impact on organizational commitment for South Korean workers, while for North Korean refugees, we confirmed that both supports have a significant impact. Third, we were unable to find any differences between the two group, in terms of other sub-components of positive psychological capital (self-efficacy, hope, and resiliency) or the sub-components of social support (informational support, tangible support). These results suggest that companies or managers employing North Korean refugee workers need to create an organizational environment that allows them to perceive social support, especially affectionate support and interaction support.

This study examined existing theories of the characteristics of the abandoned tumulus site located at the east side of the Silla era Hwang Bok Sa (皇福寺) site and attempted an archaeological approach based on the derived facts, combining both the results of this study and those of a recently conducted excavation survey. The results of this investigation exhibited the following outcomes. First, the excavation survey revealed that the huge rounded stones discovered on the surface of a rice paddy field located at the east side of the Silla era Hwang Bok Sa were all protecting stones, processed on the front side in the form of a bow, designating a royal tomb. Most of these protecting stones had deviated from their original positions due to subsequent farming practices and some had been re-cycled for construction purposes as fences or foundations for structures built in the Silla era. Considering the prevailing belief in the concept of reincarnation, the bone rank system, and royal authority in the Silla era at that time, it would seem likely that the royal tombs were not intentionally destroyed. Therefore, it is speculated that the stones in this royal tomb were abandoned during construction of the tomb of the King at that time and then naturally re-cycled as building components used in construction sites in later years. Second, this study comparatively analyzed the scale and quality of the supporting stones at the royal tomb site in Guhwang-dong. The analysis results verified that those supporting stones were the same stones from the royal tomb used as supporting stones for statues symbolizing the twelve earthly branch spirits that were restored at the site of the tower at the royal tomb. This confirmed that the statues of the twelve earthly branches spirits sitting at the Hwang Bok Sa site were the protecting stones from a different royal tomb. Accordingly, the conclusion that has been generally accepted to date-that the protecting stones of the statues of twelve earthly branches spirits sitting at Hwang Bok Sa site were probably moved from the royal tomb site in Guhwang-dong-must inevitably be modified. Third, based on the structure of the protecting stones and type of the royal tomb, it is speculated that the individual buried in the royal tomb at Guhwang-dong is one of the kings who followed King Heungdeok and similar times of the buried person of the tomb that was considered as King Gyeongdeok, and who was before the buried person of the tomb that was considered as Kim Yu-sin. In addition, when considering the historical art patterns on the supporting stones of the statues that symbolize the twelve earthly branches spirits, which were moved to the site of the tower at the royal tomb, it is reasonable to believe that the person buried at the royal tomb at Guhwang-dong is likely one of the Kings of the late Silla era of the 9^th century.

The engraved line expression in metal crafts is a detailed technique of carving or decorating metal surfaces. This technique engraves a line using a tool on the surface of a metal craft. This technique was used extensively in articles made of various metal materials during the Goryeo Dynasty, and the range of patterns that could be expressed and the width of users was wide. In this paper, based on relics and literature, the concept of line representation of this engraving technique used in the metal crafts of the Goryeo Dynasty and the perceptions and terms of the Goryeo Dynasty were examined. In addition, the users engaged in this craft and the specific patterns and patterns of decoration were reviewed. Through these means, it was possible to confirm various aspects of a technique that was thought previously to involve just simple expression of lines using tools. In addition, through the literature, Geumseokmun Gate, and relics currently being transmitted, it was possible to confirm the utilization patterns of techniques used in various types of objects. Various uses have led to the combination with other metal craft techniques that were popular at the time, and while utilizing unique characteristics of the techniques, this maximized the molding of various patterns. In the meantime, it is true that the intaglio technique in metal crafts has not received much attention compared to the decoration techniques of other metal crafts, such as inlay, embossing, and openwork techniques in which decorative effects are maximized due to the recognition that the technique was used so widely in relics. However, the universality of the technique is premised on its wide use across all eras. As such, it was used in metal craft relics that reflect the various cultural characteristics of Korea and various cultural aspects that are currently passed down. On the one hand, technology has been passed down as a form of intangible heritage that embodies a longstanding craft culture which continues to the present in the fields of sculpture and intangible cultural properties. As such, the universality of Seongak contains many cultural meanings. In addition, the uniqueness of the technique is distinct, and it is deeply related to Goryeo, who was in charge of the use of technology and craftsmanship of the Joseon Dynasty and the metal craft technology that is currently handed down. I think research on future techniques should be continued in depth.

This article is the results of excavation data and it aims to interpret the composition facilities of the Royal garden at the Wanggung-ri site. The base of research was prepared through excavation and study on the royal garden at the Wanggung-ri site, which was constructed in Sa-bi period of Baek-je. The elements for the royal garden at the Wanggung-ri site were divided in 3 parts. - 1) Stonework facility 2) Installation for conveyance of water : Large moat-shaped ditch and Winding waterway(1~6 and water catchment) 3) Square cornerstone building. In this article, I arrange the basic data about facilities and function of the royal garden for making recovery of original form. First of all, I reason that stonework facilities were in charge to make space for catchment and boundary. Especially the Round angel rectangular stonework facility took charge of complex roles as catchment and water conveyance, and water can be transferred to the large moat-shaped ditch through joint between them. I confirmed that the round angel rectangular stonework facility and the large moat-shaped ditch which were connected by joint are one of the facilities in the royal garden. The large moat-shaped ditch protected the eastern, the northern walls and workshop site under the inclined plane to minimize the damage. Also, the large moat-shaped ditch took several roles, especially water catchments and landscaping. The large moat-shaped ditch was continually used from the period of Baek-je to the unified Silla, as a result it was completely deposited inside. After that, the 6 winding waterway were built in the western inclined plane with similar needs with the large moat-shaped ditch, and the square cornerstone building was built in same time. I noticed that the square cornerstone building was built as a part of the royal garden in Sa-bi period of Baek-je through the remains of Baek-je tiles around the building. After that, the square cornerstone building was built in same place as reconstruction.

With COVID-19 spreading rapidly around the world, research and development issues on treatments and vaccines for the virus are of high interest. Among them, Remdesivir was the first to show noticeable therapeutic effects and began clinical trials, with each country authorizing the use of the drug through emergency approval. However, Gilead Co., Ltd., the developer of Remdesivir, received a lot of criticism from civic groups for submitting the application for the marketing authorization as an orphan drug. This is because when a new drug got a marketing authorization as an orphan drug could be granted an exclusive status for seven year. The long-term exclusive status of an orphan drug comes from the policy purpose of motivating pharmaceutical companies to develop treatment opportunities for patients suffering from rare diseases, which was not appropriate to apply to infectious disease treatments. This paper provides a review of the problems and improvement directions of the domestic system through comparative legal consideration against the United States, Europe and Japan for the statutes which give exclusive status to medicines. The domestic system has a fundamental problem that it does not have explicit provisions in the statute in the manner of granting exclusive status, and that it uses the review system to give it exclusive status indirectly. In addition, in the case of orphan drugs, the "Rare Diseases Management Act" and the "Regulations on Examination of Items Permission and Reporting of Drugs" provide overlapping review periods, and despite the relatively long monopoly period, there seems to be no check clause to recover exclusive status in the event of a change in circumstances. Given that biopharmaceuticals are difficult to obtain patents, the lack of such provisions is a pity of domestic legislation, although granting exclusive rights may be a great motivation to induce drug development. In the United States, given that the first biosimilar also has a one-year monopoly period, it can be interpreted that domestic legislation is quite strictly limited to granting exclusive status to biopharmaceuticals. The need for improvement of the domestic system will be recognized in that it could undermine local pharmaceutical companies' willingness to develop biopharmaceuticals in the future, and in that it is also necessary to harmonize international regulations. Taking advantage of the emergence of COVID-19 as an opportunity, we look again at the problems of the domestic system that grants exclusive rights to medicines and hope that an overall revision of the relevant legislation will be made to establish a unified legal basis.

An experiment was conducted to obtain the basic information about competitive ability of rice against weeds as affected by culm length at the Yeongnam Crop Experiment Station, Office of Rural Development in 1980. More weeds were harvested from the plot of short statured cultivar, Manseogbyeo compared to the plot of Cheongcheongbyeo that was approximately 10cm taller than Manseogbyeo regardless of planting density variables. Weeds also decreased as rice population increased from $30{\times}15cm$, $40{\times}(10{\times}10cm)$ and to $10{\times}10cm$, in order. The degree of weed suppression and floristic composition was varied depending upon plant spacing and weeding regime subjected at the previous year. The degree of weed suppression became increased with increasing rice population. The degree of weed suppression at the $10{\times}10cm$ plant spacing showed as high as hand weeding subjected in the previous year. However, in terms of floristic composition, Scirpus hotarui Roxb. became dominant when rice had cultivated at $10{\times}10cm$ plant spacing in the previous year while S. hotarui and Sagittaria pygmaea Miq. were both important in the hand weeding plot. The highest grain yield of rice showed at the $10{\times}10cm$ plant spacing while no significant difference was observed between $40{\times}(10{\times}10cm)$ and $30{\times}15cm$ plant spacings for both weeding regimes and both cultivars. However, response of grain yield to weeding regime was differed in two cultivars. For Manseobgyeo, significant grain yield decreased in no weeding plot regardless of plant spacing variables. But in case of Cheongcheongbyeo, grain yield reduction was only recognized at the $30{\times}15cm$ plant spacing. Based on these result it could be concluded that Cheongcheongbyeo (10cm taller in height) seemed to be more competitive against weeds than Manseogbyeo.

To describe the comparative awareness between media and industry, we conducted a survey with a professional group including 28 food safety managers at food corporations and 17 food journalists to find out the differences in perception of 'reporting terms' and 'correspondence terms' when food safety incident occurs. We surveyed by questionnaire methods and did the statistical analysis by SPSS. The results showed that 70.6% of the journalists and 92.9% of the corporation workers answered 'yes indeed' about the question whether the media has a great influence when food safety incident occurs. In the perception that use of the stimulating terms of the media was the cause of company damage, 83% of the corporate workers answered 'yes indeed', and 70.6% of the journalists answered 'yes'. It means that both groups agreed on stimulating terms causing company damage. In the question whether the 'reporting terms' of the media and the 'correspondence terms' of the government and academia made a difference in the consumers' perception and the spread of the incident, 92.9% of the corporate workers and 35.3% of the journalists answered 'yes indeed'. It means that both groups showed a common opinion that the difference in choice of words expanded the perception of consumers, and the spread of the incident. However, the corporate workers agreed with this in a more serious manner than the journalist group. In standardization of 'reporting terms' and restricting use, corporate workers were overall at a positive stand while journalists showed a big difference in opinion within the group. In conclusion, it is necessary to establish a measure to standardize the terms used by corporations, journalists, and professionals in order to decrease the differences of terms and the damage of consumers and the company when food safety incident occurs.

Background: Vocabularies originating from Chinese characters constitute an important common factor in the medical terminologies used 3 eastern Asian countries; Korea, China and Japan. This study was performed to comparatively analyze the medical terminologies of these 3 countries in the field of cardiopulmonary bypass (CPB) and; thereby, facilitate further understanding among the 3 medical societies. Material and Method: A total of 129 English terms (core 85 and related 44) in the field of CPB were selected and translated into each country's official terminology, with help from Seoul National University Hospital (Korea), Tokyo Michi Memorial Hospital(Japan), and Yanbian Welfare Hospital and Harbin Children Hospital (China). Dictionaries and CPB textbooks were also cited. In addition to the official terminology used in each country, the frequency of use of English terms in a clinical setting was also analyzed. Result and Conclusion: Among the 129 terms, 28 (21.7%) were identical between the 3 countries, as based on the Chinese characters. 86 terms were identical between only two countries, mostly between Korea and Japan. As a result, the identity rate in CPB terminology between Korea and Japan was 86.8%; whereas, between Korea and China and between Japan and China the rates were both 24.8%. The frequency of use of English terms in clinical practices was much higher in Korea and Japan than in China. Despite some inherent limitations involved in the analysis, this study can be a meaningful foundation in facilitating mutual understanding between the medical societies of these 3 eastern Asian countries.

Radiation use efficiency (RUE), the amount of biomass produced per unit intercepted photosynthetically active radiation (PAR), constitutes a main part of crop growth simulation models. The objective of the present study was to evaluate the variation of RUE of rice plants under various nitrogen nutritive conditions. from 1998 to 2000, shoot dry weight (DW), intercepted PAR of rice canopies, and nitrogen nutritive status were measured in various nitrogen fertilization regimes using japonica and Tongil-type varieties. These data were used for estimating the average RUEs before heading and the relationship between RUE and the nitrogen nutritive status. The canopy extinction coefficient (K) increased with the growth of rice until maximum tillering stage and maintained constant at about 0.4 from maximum tillering to heading stage, rapidly increasing again after heading stage. The DW growth revealed significant linear correlation with the cumulative PAR interception of the canopy, enabling the estimation of the average RUE before heading with the slopes of the regression lines. Average RUE tended to increase with the increased level of nitrogen fertilization. RUE increased approaching maximum as the nitrogen nutrition index (NNI) calculated by the ratio of actual shoot N concentration to the critical N concentration for the maximum growth at any growth stage and the specific leaf nitrogen $(SLN;\;g/m^2\;leaf\;area)$ increased. This relationship between RUE (g/MJ of PAR) and N nutritive status was expressed well by the following exponential functions: $$RUE=3.13\{1-exp(-4.33NNNI+1.26)\}$$ $$RUE=3.17\{1-exp(-1.33SLN+0.04)\}$$ The above equations explained, respectively, about 80% and 75% of the average RUE variation due to varying nitrogen nutritive status of rice plants. However, these equations would have some limitations if incorporated as a component model to simulate the rice growth as they are based on relationships averaged over the entire growth period before heading.

Rough rice samples of four rice varieties were collected from twenty five locations through the country just after 1986 rice growing season. Various characteristics related to rice grain quality were observed to clarify the degree of locational variation of physico-chemical properties, and cooking and eating quality of rice grains. Grain weight, grain shape, degree of translucency and chalkiness of rice grain, amylogram properties of rice flour, water uptake during cooking, and cooked rice appearance were different between varieties tested. High degree of locational variation were found in following characteristics, degree of translucency and chalkiness of rice grain, water uptake during cooking, cooked rice appearance and amylogram properties. Eating quality of cooked rice indicated by sensory score showed different tendency of locational variation between rice varie-ties tested, and locations produced rice grains showing better eating quality were not coinside with among varieties tested. Grain weight, degree of translucency and chalkiness of rice grain, and cooked rice appearance of rice samples showing better eating quality were quite different to rice grains showing poor eating quality. Rice having better eating quality of a japonica variety, Chucheong, showed higher value of peak and final viscosity, viscosity after cooling, consistency and set back on amylograph compared with those of poor eating quality rices, and break down value of better rice was lower than that of poor rice. However, a Tongil type variety, Taebaek, did not show any consistent difference between better and poor rices. Rice samples from six locations in Chucheong and four locations in Taebaek showed special properties on amylogram compared with other rices collected in this study.
