Korea has established a code for the economic and cultural industry that covers a wide range of classes unlike the old information era which was limited to the simple knowledge, technology, tools, morals, and customers that had been established in our society. On the other hand, 'culture marketing' is a series of marketing activities in which value-added items are created and shared. The combination of business management and culture seemed pretty awkward considering how rapidly the world was changing, however, the nature of today's culture has changed and the economic nature of culture products has resulted from those changes. In this paper, two authors who expressed the cultural identity in the culture products are studied through a comparison analysis; the author Min Yeongsoon expressed the identity confusion that she experienced in a foreign country and how she overcame homesickness in her work; and the author Kim Ata expressed his confidence in Asia and used his clear and loud voice to express the culture in his work. In addition, today's culture products are affected by the surrounding cultures such as the member's traditional society, environmental culture, and individual's culture. It is a good source for good works of art. In this study, the efforts of seeking the cultural identity, structuring the concept, seeking a new market and possibilities are used to make a consistent process in order to make a series of the systems required for planning and developing culture products.

최근 지식경영의 중요성이 부각됨에 따라 데이터웨어하우징에 대한 관심이 집중되고 있다. 특히 온라인 분석 처리(On-Line Analytical Processing : OLAP) 시스템은 데이터 데이터하우징의 효과적인 활용 방안으로 많은 종류의 OLAP 제품들이 공급되어 왔다. 그러나 OLAP 기술은 실제로 아무런 표준 없이 매우 오랫동안 사용되어 왔으며, 이러한 다양성은 여러 OLAP 제품들 간에 데이터 교환과 인터페이스를 매우 어렵게 했다. 이에 본 논문에서는 서로 다른 OLAP 제품들간에 공통적으로 사용할 수 있는 OLAP 메타데이터 교환 모델을 설계하고, 그 메타데이터를 기반으로 생성된 큐브들을 교환할 수 있도록 하는 OLAP 메타데이터 교환 시스템을 구현하였다. OLAP 메타데이터 교환 모델의 설계는 XML을 사용하였고, 시스템의 사용자 인터페이스는 웹기반으로서 여러 OLAP 제품들과 메타데이터를 주고받을 수 있는 환경을 제공하였다. 사용자는 OLAP 제품들의 복잡한 큐브 생성 과정을 특별히 습득할 필요가 없으며, 하나의 큐브로 여러 제품들이 제공하는 서로 다른 분석 환경을 경험할 수 있다. 본 연구를 확장하여 OLAP 제품들이 공통으로 사용될 수 있는 질의 언어를 설계하고 적용 할 수 있다면 OLAP 제품들간의 원활한 의사소통이 이루어질 수 있을 것으로 전망한다.

Currently, the leakage of internal information has emerged as one of the most significant security concerns in enterprise computing environments. Especially, damage due to internal information leakage by insiders is more serious than that by outsiders because insiders have considerable knowledge of the system's identification and password (ID&P/W), the security system, and the main location of sensitive data. Therefore, many security companies are developing internal data leakage prevention techniques such as data leakage protection (DLP), digital right management (DRM), and system access control, etc. However, these techniques cannot effectively block the leakage of internal information by insiders who have a legitimate access authorization. The security system does not easily detect cases which a legitimate insider changes, deletes, and leaks data stored on the server. Therefore, we focused on the insider as the detection target to address this security weakness. In other words, we switched the detection target from objects (internal information) to subjects (insiders). We concentrated on biometrics signals change when an insider conducts abnormal behavior. When insiders attempt to leak internal information, they appear to display abnormal emotional conditions due to tension, agitation, and anxiety, etc. These conditions can be detected by the changes of biometrics signals such as pulse, temperature, and skin conductivity, etc. We carried out experiments in two ways in order to verify the effectiveness of the emotional recognition technology based on biometrics signals. We analyzed the possibility of internal information leakage detection using an emotional recognition technology based on biometrics signals through experiments.

Background: Knowledge on microclimate conditions under artificial shades in a ginseng field would facilitate climate-aware management of ginseng production. Methods: Weather data were measured under the shade and outside the shade at two fields located in Gochang-gun and Jeongeup-si, Korea, in 2011 and 2012 seasons to assess temperature and humidity conditions under the shade. An empirical approach was developed and validated for the estimation of leaf wetness duration (LWD) using weather measurements outside the shade as inputs to the model. Results: Air temperature and relative humidity were similar between under the shade and outside the shade. For example, temperature conditions favorable for ginseng growth, e.g., between $8^{\circ}C$ and $27^{\circ}C$, occurred slightly less frequently in hours during night times under the shade (91%) than outside (92%). Humidity conditions favorable for development of a foliar disease, e.g., relative humidity > 70%, occurred slightly more frequently under the shade (84%) than outside (82%). Effectiveness of correction schemes to an empirical LWD model differed by rainfall conditions for the estimation of LWD under the shade using weather measurements outside the shade as inputs to the model. During dew eligible days, a correction scheme to an empirical LWD model was slightly effective (10%) in reducing estimation errors under the shade. However, another correction approach during rainfall eligible days reduced errors of LWD estimation by 17%. Conclusion: Weather measurements outside the shade and LWD estimates derived from these measurements would be useful as inputs for decision support systems to predict ginseng growth and disease development.

Mercury (Hg) is a global environmental pollutant that has been the cause of many public concerns. One particular concern about Hg in aquatic systems is its trophic transfer and biomagnification in food chains. For example, the Hg concentration increases with the increase of food chain level. Fish at the top of food chain can accumulate high concentrations of Hg (especially the toxic form, methylmercury, MeHg), which is then transferred to humans through seafood consumption. Various biological and physiochemical conditions can significantly affect the bioaccumulation of Hg-including both its inorganic (Hg(II)) and organic (MeHg) forms-in fish. There have been numerous measurements of Hg concentrations in marine and freshwater fish worldwide. Many of these studies have attempted to identify the processes leading to variations of Hg concentrations in fish species from different habitats. The development of a biokinetic model over the past decade has helped improve our understanding of the mechanisms underlying the bioaccumulation processes of Hg in aquatic animals. In this review, I will discuss how the biokinetic modeling approach can be used to reveal the interesting biodynamics of Hg in fish, such as the trophic transfer and exposure route of Hg(II) and MeHg, as well as growth enrichment (the increases in Hg concentration with fish size) and biomass dilution (the decreases in Hg concentration with increasing phytoplankton biomass). I will also discuss the relevance of studying the subcellular fates of Hg to predict the Hg bioaccessibility and detoxification in fish. Future challenges will be to understand the inter- and intra-species differences in Hg accumulation and the management/mitigation of Hg pollution in both marine and freshwater fish based on our knowledge of Hg biodynamics.

This research was an attempt to make it possible to provide nursing care and health education meet- ing the need not of care givers but of patients by identifying the nature of patients' self regulation experiences. The specific objective of this study was : 1) to explore self regulation experiences of patients with adult disease. The phenomenological approach in qualitative studies is used to serve this purpose. Colaizzi's method is used for the phenomenological analysis of the data in this study, which were collected from 25 patients hospitalized in the internal medical ward and oriental medical ward of a Seoul hospital, suffering from adult disease such as hypertension, arteriosclerosis and diabetes mellitus. The research was conducted over a period of March to September, 1994. The investigator conducted participated observations and in-depth unstructured interviews which were audiotaped under the permission of patients. The investigator read the data repeatedly to identify and categorize significant statements, formulating meanings, themes and theme clusters. The result is categorized as follows : Self regulation activities, their barriers and predisposing factors of a disease. Thirteen theme clusters of self regulation activities related to health identified were. “maintaining diet regimen”, “maintaining exercise regimen”, “maintaining medication regimen”, “maintaining oriental medical regimen”, “maintaining health monitoring regimen”, “maintaining self effort”, “maintaining religious life”, “maintaining social sup-port systems”, “maintaining peaceful mind”, “maintaining moderation in life”, “maintaining sincere attitude in life”, “maintaining natural life”, and “maintaining folk remedy” This findings confirm the fact that self regulation is complicatedly and diversely influenced by oriental medicine and folk remedy, and Korean traditional ideas melted in Confucianism, Buddhism, Taoism and Shamanism, and modern medical care and western culture. Seven theme clusters of self regulation barriers identified were : "lack of knowledge and self aware-ness", "lack of social supports", "lack of awareness of need in continuous regimen and treatment", "dissatisfaction with hospital and health care provider", "lack of self management ", "lack of will to combat illness", and "overconfidence in folk remedy" Four theme clusters of predisposing factors of a disease were : "cumulation of stressors", "fatalism", "careless life style", and "family history". In conclusion, this. study will prove helpful not only in understanding clients in light of our traditional culture but also in providing them with the kind of nursing care and health education satisfying their demands and particularly cultural needs.
