The mineral contents, and free amino acid, and fatty acid composition of rack and bag or suspended cultured oysters Crassostrea gigas were compared. The moisture content did not change much from 82.8% to 86.3% in the different culture methods. The glycogen level was low 4.7% during rack and bag culture but high 7.2% during suspended culture. The sodium level was the highest during suspended culture, while copper and zinc level were highest during rack and bag culture. The taurine level was 1,385-1,375 mg/100 g in oyster cultured using the rack and bag method, but that in the market sample was lowest at 1,015.8 mg/100 g. Hydroxyproline, glutamic acid, proline, glycine, and alanine were detected at high levels in the experimental oysters. The polyunsaturated fatty acid content was similar among samples. The docosahexaenoic acid level was 14% with rack and bag culture and 12% with suspended culture, whereas the eicosapentaenoic acid level was 15% with rack and bag culture and 20% with suspended culture. The atherogenic index (AI), thrombogenicity index (TI), and hypocholesterolemic/ hypercholesterolemic (h/H) ratio were important factors in the nutritional evaluation. The AI and TI values were 0.5-0.2, and the h/H ratio were 2.0 and 2.4 with the rack and bag and suspended culture, respectively.

The productivity of ultra-small rotifer, Synchaeta kitina was investigated at the exchange rate of culture water (10, 20, 30, 40 and 50%) and initial inoculation densities (250, 600 and 900 inds. per mL) in semi-continuous culture. Also, the possibility of mass culture was investigated in a 100 L culture tank. Tetraselmis suecica was used as the feed for S. kitina in all experiments. The production of S. kitina increased with an increase in exchange rate of culture water. The highest production ($82.0{\times}10^5$ inds.) was achieved at 40% exchange rate of culture water. The production of S. kitina increased with an increase of initial inoculation density during the first week and the highest total production ($17.4{\times}10^6$ inds.) was achieved at 900 inds. per mL of initial inoculation density. However, on the second week, all treatments were not significantly different in total production (P>0.05). During the two weeks, total production of S. kitina at 900 inds. per mL of initial inoculation density was higher than at 600 inds. of initial inoculation density, but there was no significant difference (P>0.05). In the 100 L culture tank, density of S. kitina was kept from 516 to 890 inds. per mL and S. kitina was daily harvested $15.5{\times}10^6$ to $26.7{\times}10^6$ during the experimental period. The production cost for 100 million rotifers in semi-continuous culture was 63,656 won. The results from this study indicate that the optimal exchange rate of culture water and initial inoculation density for the semi-continuous culture of ultra-small rotifer, S. kitina are 40% and 600 inds. per mL, respectively.

Objective: This paper introduces the regulatory oversight approaches and issues to consider in the course of safety culture oversight model development in the nuclear field. Common understanding on regulatory oversight and present practices of international communities are briefly reviewed. The nuclear safety culture oversight model of Korea is explained focusing on the development of safety culture definition and components, and their basic meanings. Oversight components are identified to represent the multiple human and organizational elements which can affect and reinforce elements of defense in depth system for nuclear safety. Result of validation study on safety culture components is briefly introduced too. Finally, the results of the application of the model are presented to show its effectiveness and feasibility. Background: The oversight of nuclear licensee's safety culture has been an important regulatory issue in the international community of nuclear safety regulation. Concurrent with the significant events that started to occur in the early 2000s and that had implications about safety culture of the operating organizations, it has been natural for regulators to pay attention to appropriate methods and even philosophy for intervening the licensee's safety culture. Although safety culture has been emphasized for last 30 years as a prerequisite to ensure high level of nuclear safety, it has not been of regulatory scope and has a unique dilemma between external oversight and the voluntary nature of culture. Safety culture oversight is a new regulatory challenge that needs to be approached taking into consideration of the uncontrollable aspects of cultural changes and the impacts on licensee's safety culture. Although researchers and industrial practitioners still struggle with measuring, evaluating, managing and changing safety culture, it was recognized that efforts to observe and influence licensees' safety culture should not be delayed. Method: Safety culture components which regulatory oversight will have to focus on are developed by benchmarking the concept of physical barriers and introducing the defense in depth philosophy into organizational system. Therefore, this paper begins with review of international regulatory oversight approaches and issues associated with the regulatory oversight of safety culture, followed by the development of oversight model. The validity of the model was verified by statistical analysis with the survey result obtained from survey administration to NPP employees in Korea. The developed safety culture oversight model and components were used in the "safety culture inspection" activities of the Korean regulatory body. Results: The developed safety culture model was confirmed to be valid in terms of content, construct and criterion validity. And the actual applicability in the nuclear operating organization was verified after series of pilot "safety culture inspection" activities. Conclusion: The application of the nuclear safety culture oversight model to operating organization of NPPs showed promising results for regulatory tools required for the organizations to improve their safety culture. Application: The developed oversight model and components might be used in the inspection activities and regulatory oversight of NPP operating organization's safety culture.

Despite the development of the aviation industry, aircraft accidents caused by human errors by flight crews continue to occur. In order to reduce such human error accidents, it is important to strengthen flight-related regulations and establish a safety culture in which pilots themselves seek to ensure flight safety, rather than requiring flight crew members to follow them. In this study, the sub-concept of safety culture was classified into three latent variables (safety management, safety atmosphere, and process culture) and eight measured variables to investigate the safety culture awareness of domestic flight crew. The survey results were analyzed by type of airline and flight crew. The purpose of this study is to present a plan to improve the performance of revitalizing the safety culture of domestic flight crew through an empirical comparative analysis according to the number of flight hours and years of service at the airline.

This study discusses the traditional main life culture of Korea and the relations with the traditional manners of Korean culture. According to studies of literature and an analysis, it shows the traditional courtesy can be linked to the housing structure of the Cho-sun dynasty which can be termed as a representation of traditional Korean society. Housing culture of Cho-sun dynasty led to a most characteristic living culture. To be specific sit-down culture use norms, hierarchy and fittings can be sited. The sit-down culture in turn led to the main courtesies of greeting, table manners, etiquette for entrance and exit, the carefulness shown to elders, the self-restraint of speech and action and the manners between men and women, But in today's world there are realistic difficulties that make the application of these norms in everyday life difficult. But at the same time we must realize that there are traditional norms which overcome time and which affect today's norms.

This paper aims to propose teaching plans based on individual learner's experience and from a cross-cultural viewpoint by applying Currere as a method of Korean life-culture education. Current Korean culture education programs are not systematic, and are being executed without differentiation from language education. Thus, this study proposes Korean life-culture teaching plans based on the method of Currere. We suggested Currere teaching-learning stages and strategies for Korean language learners by adapting Pinar's and Jeong Seong-a's method of Currere. The Currere teaching-learning stages consisted of introduction, regression, progression, theme analysis, data analysis, group discussion, and integration. Although the method of Currere is implemented through autobiographic writing, this study added the strategies of 'personal experience telling' and 'schema utilization and background knowledge provision'. In order to enhance the applicability of Currere to Korean life-culture education, we suggested teaching plans for the theme of "How to dispose rubbish" as an example. We suggested detailed teaching plans that teachers can apply in the actual classroom. We expect that these teaching plans may be applied to actual classes so that Korean culture education may not be limited to the acquisition of knowledge, but be linked to their real life.
