The dairy industry has consistently grown via the expansion of dairy-based food categories. Dairy product consumption is stable since the nutrient composition in dairy products is ideal for human health. However, dairy products are highly susceptible to food-borne pathogens. Controlling the safety of dairy products is thus important when considering the nutrient-rich matrix of this food category. Currently, immunoassays or molecular biology techniques have been used to evaluate the safety of dairy products in Korea. These methods are based on the detection of proteins and thus have low reproducibility and sensitivity. Recent techniques to detect food-borne pathogens have focused on genetic analyses. Rapid detection methods for food-borne pathogens in milk and dairy products using polymerase chain reaction (PCR) techniques, such as conventional PCR, real-time PCR, repetitive sequence-based (rep)-PCR, PCR-denaturing gradient gel electrophoresis (DGGE), and digital PCR, are reviewed in this article. The aim of this review was to contribute knowledge of the relationship between microflora and the quality of dairy products. This study will also assist in the immediate monitoring of food-borne pathogens in milk and dairy products when an outbreak related to this food category occurs.

Stimulated polariton scattering (SPS) from the $A_1$ transverse optical (TO) modes of $BaTiO_3$ bulk crystal generating a terahertz (THz) wave with the noncollinear phase-matching (NPM) condition is theoretically investigated. To our best knowledge, this is the first report on THz wave generation from $BaTiO_3$ bulk crystal via SPS. Phase-matching (PM) characteristics in the NPM configuration are analyzed. Effective parametric gain lengths for the Stokes and THz waves in the NPM configuration are calculated. The effective parametric gain coefficient and absorption coefficient of the THz wave in $BaTiO_3$ are theoretically simulated. The THz phonon flux densities generated via SPS in $BaTiO_3$ are theoretically calculated by solving the coupled wave equations under the NPM condition. The PM characteristics and THz-wave parametric gain characteristics in $BaTiO_3$ are compared to those in $MgO:LiNbO_3$. The results of the analysis indicate that $BaTiO_3$ is an attractive optical crystal for efficient THz wave generation via SPS.

Recently, there has been a steady decrease in the proportion of the construction sector among Korean engineering firms. Thus it is essential for Korean engineering firms in the construction sector, which lack experience in overseas ventures, to identify and improve their competitiveness for successful overseas expansion. Therefore, in this study, changes in Korean engineering firms' capabilities for the last decade were analyzed to promote entry into overseas road and water resource engineering markets. Competency factors that require urgent improvement were derived based on Importance-Performance Analysis (IPA) as a tool for quantitative measurement. As a result, the factor that shows low performance compared to the importance is an overall understanding of the target country in the road and water resource areas. Knowledge of regulatory issues on design, the ability of time management software, and knowledge of the regulatory problems on construction safety are also insufficient. This study can be used as a research methodology to identify competitiveness that Korean engineering firms have to strengthen when they advance into overseas markets in roads, water resources, and other areas.

We analyzed the data on medicinal plants and related traditional knowledge in Korea and China using data analysis method. There are 108 families 214 genera 542 species, and 202 families 660 genera 1,261 species were found in Korea and China respectively. Total of 86 families (79.6%) and 130 genera (60.7%) were in common both countries. More than one information were recorded in many species, however, there was only one information from some species (32.7% of genera in Korea, and 58.8% of genera in China). The most frequent appeared plant family was Compositae (Asteraceae) in both countries (8.4% in Korea and 10.7% in China) and followed by Rosecease and Leguminocae (Fabaceae). Plant parts were classified 11 parts and roots were mostly used in Korea and whole plants in China. Usages were described in different terms of ailments or symptoms. There are 120 usage in Korea and 230 in China. Plant uses for the ailment or symptoms are pain, digestive system disorder, cold and etc. in Korea. In China, plants were mostly used for clear heat, digestive system disorder, cough and etc. Relation between the plant and ailment(symptom) of the top 10 plants in Korea and China was different although from same plant family. We also analyzed the relations between plant species and part used, and plants parts and ailment(symptom). With the data analysis method, we were able to collect the medicinal plant resources data and found the differences in plant resources, usage, and plant part for use. The result provide important information of the plant resources and related traditional knowledge of Korea for use of plant resources in industry and facilitate to plan a strategy to cope with Nagoya Protocol in the future.

Purpose: This micro-ethnographic study aimed to understand coping experiences of Korean-American (K-A) women after diagnosis with breast cancer due to a hereditary gene mutation. Methods: Participatory observation and in-depth interviews were performed at one breast cancer screening center in Southern California, in 2005 with eleven first generation K-A immigrant women. All transcribed interviews and field notes were analyzed using ethnographic methodology. Results: K-A women's experience varied based on acculturation risk factors including: limited English speaking ability; disrupted family relationships, individualistic family values, or intergenerational communication barriers; lack of Korean speaking nurses; and Korean physicians' who lacked knowledge about hereditary breast cancer risk. These risk factors led to isolation, loneliness, lack of emotional and social support. In comparison to Korean homeland women in a similar medical situation, these K-A immigrants felt disconnected from the healthcare system, family support and social resources which increased their struggling and impeded coping during their survivorship journey. These women were not able to access self-support groups, nor the valuable resources of nurse navigator programs. Conclusion: Professional oncology associations for nurses and physicians have a moral obligation to support and promote knowledge of hereditary cancer risk and self-help groups for non-native speaking immigrants.

This paper investigates how strategy formulation and implementation processes used by the University of Cape Coast (UCC) in building its digital collections compare with the Andrew's strategic formulation and implementation theoretical framework. Theory-testing case study methodology was used. The data collection instruments were the key informant interview technique and document reviews. During the formulation phase, two aspects (resources and aspirations of senior management) were emergent. During the implementation phase, five aspects (achieving results, processes and behaviour, standards, motivation, personal) were emergent. All other elements of building the UCC digital collections were planned during both the formulation and implementation phases. Although the emphasis on students and learning is laudable and apt, there seems to be lack of focus on research support beyond digital collection building, despite the fact that research excellence is one of the UCC's key priorities. Opportunities exist for improving feedback mechanisms between the users, digital library staff and the university management; and inclusion of social media tools in the digital library project. Since only the experience of a single institution of higher learning is considered, it cannot be definitively stated that strategy formulation and implementation will be similar in every institutional context. However, the results provide a basis for academic digital libraries to draw lessons from this case. In African public universities, there is little earlier research on strategy formulation and implementation in digital library management. Strategy formulation and implementation is a critical issue for higher education academic libraries especially in developing countries like Ghana, due to limited financial resources and the rapid change in the information environment during the last several decades.

Objectives : The purpose of this study is to provide resources to develop oral health education programs to make schoolchildren be able to do oral care behaviors voluntarily by analyzing the factors affecting elementary school students's oral health behaviors. Methods : A self administered questionnaire based survey was conducted with 233 students (117 boys, 116 girls) of sixth graders at Gyeonggi Province from September 1st to October 2nd, 2012. Researchers explained to willing participants the purpose of this study and then, asked respondents to complete their own questionnaire. A total of 233 questionnaires were properly completed while 7 questionnaires had insincere sections and were thus excepted. Results : 1. Children's higher level of oral health-related knowledge have more positive oral health attitudes(p=0.000) and oral health behaviors(p=0.001). 2. The higher oral health behavior mothers have, the more students have oral health knowledge and better oral health attitude, the higher the oral health behavior children have(p<0.01). 3. Students' positive attitude towards oral health(${\beta}$=0.548, p=0.000) and Mother's more attention to Oral check after tooth-brushing(${\beta}$=-0.149, p=0.005) were associated with children's sound dental health behaviors. Conclusions : The findings of this study suggest that the oral health knowledge, attitude and behaviors are associated with students' oral health behavior. Thus, effective support in oral health education, is need to be enhanced among the elementary school students rather than only focus on conveying knowledge to them. Since, mother's oral health-related knowledge and attitudes on the tooth-brushing behaviour and dental health of their children influence on child's oral health, the development of Comprehensive oral health education program into the mother and child needs to be carried out.
