  • The concept of carrying capacity for bivalve culture of an area can be classified into four hierarchical categories, according to their level of complexity and scope, such as physical, production, ecological and social carrying capacity. Most scientific efforts to date have been directed towards modelling production carrying capacity and some of the resultant models have been used successfully. But, the modelling of ecological carrying capacity is still in its infancy, because it should consider the whole ecosystem and all culture activities. A more holistic approach is needed to determine the influence of bivalve aquaculture on the environment and ecological carrying capacity. As an alternative, we can use a set of ecological indicators which can show the environmental performance of bivalve farms and assess ecological carrying capacity. Clearance efficiency and filtration pressure indicators show the value of 0.331 and 0.203, respectively, and these indicators suggest that the present level of culture in GeojeHansan Bay is above the ecological carrying capacity of 0.05. Consequently, these indicators can provide a guidance on the present level of culture in regard to production and ecological carrying capacity in GeojeHansan Bay.

  • This study is planned to present the future direction of the study of Korean clothes through the realistic recognition of the changes of studying issues of each area of the related clothes. For this purpose, the writer of this thesis have collected, classified and analyzed those various kinds of papers and theses published in the professional magazines of clothes such as Journal of Korean Home Economics, Journal of the Korean Society of Clothing and Textiles, Journal of the Korean Society of Costume, The Research Journal of the Costume Culture so that I might examine and study the main trend of the related study. The result of the study is as follows. 1. Since the first publication of Journal of Korean Home Economics in 1959 and Journal of the Korea Society of Clothing and Textiles, and Journal of the Korean Society of Costume, the study of clothes has been gradually increased. Furthermore, since 1990 the issuing times of various kinds of Journals have been continuously increased with the foundation of The Research Journal of the Costume Culture and Journal of Fashion Business. 2. Theses and papers published in the four greatest Journals of Korean Clothing and Textiles have been studies for the detailed classification and analysis of the data. According to the study, It is found that the theses in Journal of the Korea Society of Clothing and Textiles have actively studied textiles as they had studied before 1990s and those in Journal of the Korean Society of Costume have studied history of costumes and those in The Research Journal of the Costume Culture have studied the composition and science of clothes. 3. The order of studying subjects was 1) Design and Aesthetics, 2) Fashion Merchandising 3) Textiles, 4) Clothing Construction, 5) History of Costumes, 6) Costume Culture, 7) Socio-Psychology of clothing, 8) Others. Considering the above mentioned result of the study, most of the main fields of the clothing and textiles study have been studied continuously in balance since 1990 unlike the past although the past studies had been performed largely in some main fields only. And it was found that fields of clothing styles and clothing goods have been studied most actively since 1990s. 4. The studying field of Design and Aesthetics has showed to have the trend to be studied very actively since 1990s, which has utilized various relevant data with scholastic approach to psychology and aesthetics. Regarding Fashion Merchandising, the study of consumers decision process has been performed most actively. And theses on the international trades have been published considerably more than ever before, which resulted in gradual increase in gradual increase in the study of the fields related with global marketing, internet marketing, textile products exports, and overseas brands, etc. Regarding Textiles, the field of clothing sanitation and management has been studied more actively than that of clothing materials. In case of clothing construction, the study of physical styles and pattern making has been more active than the other related fields. Fields of socio-psychology of clothing and history costume have been a little reduced. Field of costume culture has been firmly rooted as an independent subject to be studied in the clothing related study. And study of the clothes has shown various trends of studies of ethnic & folk clothes, religious and ceremonial garments, linguistic & favorite approach to clothes and academic analysis of the data.

  • This study aims to emphasize the importance of organizational culture through case studies on the activation of Atomy corporate culture, which is a key factor in corporate sustain-ability. A company is a purely Korean network marketing company that is advantageous to consumers, and further enhances the sustainable growth system by realizing the value of A company that realizes customer's success beyond customers' with better quality and more reasonable prices. In particular, A company has the following three characteristics of organizational culture to realize its founding philosophy, motto, management goals and management policy. First, it is a culture of Observing Principles. Second, it is a culture of glowing together. Third, it is a sharing culture. In addition, A company established and practiced, a unique thinking and organizational culture characteristic of work, to realize growth and development of a top-notch company beyond a global Korean network marketing company. On the other hand, A company is realizing the re-establishment and implementation of the human resource management system that strategically reflects the value of industry according to the changes and characteristics of the times. In other words, the most important factor for revitalizing the organizational culture is the aspect of changes in the personnel system. We are further improving our sustain-ability management system through system innovation to provide continuous value to our partners, members, and consumers along with a strategic HR system differentiated from existing network marketing companies.

  • In this research, it was examined whether the importance of value of self(i.e., self-referenced values) and the perceived importance of values of average Koreans(i.e., culture-referenced values) differ according to social class. In Study 1, differences in the importance of self-referenced values according to the social class of 1,140 adults aged over 19 years old were examined using Korean data from the World Values Survey. Findings showed that higher social class was associated with higher levels of Hedonism (which belongs to the individualistic value domain) and Benevolence, and lower levels of Tradition (which belongs to the collectivistic value domain) and Universalism. In Study 2, culture-referent questionnaires were added to examine the differences in self-referenced values and culture-referenced values according to social class. Findings showed that higher social class was associated with greater importance attached to individualistic value domain (namely, Power and Achievement), and as a result of Study 1, less importance attached to Benevolence towards the self. On the contrary, for culture-referent ratings, higher social class was associated with lower perceptions of the importance of individualistic value domain (namely, Self-direction and Hedonism) and greater importance attached to Tradition (which belongs to the collectivistic value domain) for average Koreans. These results suggest that the importance of self-referenced values and culture-referenced values differ by social class. The need for social class research taking into account culture and the importance of the culture-referent ratings is highlighted. Future directions for research are discussed.

  • A production of $\beta-Carotene$was attempted in a fed-batch culture of Blakeslea trispora by controlling both foam and dissolved oxygen in the presence of surfactant, Span 20. Results obtained from the shake flask cultures indicated that a high concentration of dissolved oxygen was needed for both cell growth and $\beta-Carotene$ synthesis, and the optimal concentration of glucose was found to be in the range of 50-100 g/l. In order to maintain the dissolved oxygen concentration level at higher than 50% of air saturation, pure oxygen was automatically sparged into the medium with air. Foam was controlled by bypassing air from the submerged aeration to the headspace in response to the foam that was caused by Span 20. High agitation speed was found to be detrimental to the cell growth due to shear damage, even though it provided sufficient dissolved oxygen. On the other hand, a low aeration speed caused stagnant regions in the fermentor because of improper mixing. Thus, for the fed-batch operation, agitation speed was increased gradually from 300 to 700 rpm to prevent cell damage at the initial stage of fermentation and to give efficient mixing for a viscous culture broth as the culture proceeded. By controlling dissolved oxygen and foam, a high concentration of $\beta-Carotene$otene (1,190 mg/l) was obtained in 6 days of the fed-batch culture of B. trispora with 2.5% of the dry cell weight, which was approximately 5 times higher than that of the batch cultures.

  • In Salmonella enterica serovar Typhimurium, many genes encoded within Salmonella pathogenicity island 1 (SPI1) are required to induce intestinal/diarrheal disease. In this study, we compared the expression of four SPI1 genes (hilA, invF, prgH, and sipC) under shaking and standing culture conditions and found that the expression of these genes was highest during the transition from the exponential to stationary phase under shaking conditions. To identify regulators associated with the stationary phase-dependent activation of SPI1, the effects of selected regulatory genes, including relA/spoT (ppGpp), luxS, ihfB, hfq, and arcA, on the expression of hilA and invF were compared under shaking conditions. Mutations in the hfq and arcA genes caused a reduction in hilA and invF expression (more than 2-fold) in the early stationary phase only, whereas the lack of ppGpp and IHF decreased hilA and invF gene expression during the entire stationary phase. We also found that hfq and arcA mutations caused a reduction of hilD expression upon entry into the stationary phase under shaking culture conditions. Taken together, these results suggest that Hfq and ArcA regulate the hilD promoter, causing an accumulation of HilD, which can trigger a stationary phase-dependent activation of SPI1 genes under shaking culture conditions.

  • For any research study, in order to achieve the researcher's intended purpose, the depth of research is added, and the area of the subject is expanded by clearly defining the scope and objective. The study was undertaken to analyze the bibliographic data of 254 papers in the field of foodservice and restaurant published in the Journal of the Korean Dietary Culture from 2002 to 2021. The study was divided into two periods: 2002 to 2011, and 2012 to 2021. Research topics were derived and research trends according to temporal changes were confirmed through analysis of keyword networks by period. In addition, analyzing the keyword network of simultaneous appearance of "foodservice" and "restaurant", the research topics were compared and analyzed in relation to which keywords were expanded by period. Our analysis revealed that the research topics were mostly studied for satisfaction and nutrition. Additionally, they were classified into procurement, Korean food before employee menu, marketing, restaurant industry, and quality. In the period from 2002 to 2011, it was confirmed that studies encompassed a wide range of research topics, focusing on foodservice and restaurant; in the second period from 2012 to 2021, the research topics were more classified and subdivided.

  • This study was conducted with the following three study objectives. First, effects of safety awareness level of lab researchers to the improvement of safety culture in the organization Second, effects of organizational safety behaviors to the improvement of safety culture Third, test of mediating effects of organizational safety behaviors in the relationship between safety awareness level and the improvement of safety culture. The results show that organizational safety behavior is an indispensable factor for the improvement level of safety culture. Especially, the factors in safety training activities, safety compliance and management system are mediating variables which affect the safety awareness level and improvement level of safety culture, which shows these variables are very important factors in reducing safety accidents through the improvement of safety culture. Therefore, safety behaviors in the organization should be considered with priority. If the organization leads to improve safety awareness through regular safety training and rewards and punishes according to the test results, safety awareness could be improved. This study was conducted to identify the necessary factors to improve the overall safety culture in the organization and contribute to the diffusion of safety culture by improving the safety training awareness of the researchers.

  • Plant cell culture can be divide into two classes non-organic culture and organic culture. Non-organic culture such as suspension culture has many researches, however organic culture about recombinant protein production has little researches. Recombinant protein produced through organ culture is quite stable and it can make proteins by itself without any grow regulators. Therefore organ culture is much easier than other methods. In this research, we used transformed tobacco seed. At first we germinated the seed then separated stems and leaves from the grown plant. And raised in liquid medium by in vitro vegetative reproduction. Continuing most suitable conditions, we compared the Quantities of recombinant protein from intra cellular with from extra cellular. And adding some permeabilizing agents (Pluronic F-68, Triton X-100, DMSO, PEG8000), we increased the productivity of the recombinant protein.
