Purpose: The purpose of this study was to investigate the patient safety culture in Korean nursing homes using the Nursing Home Survey Patient Safety Culture (NHS-PC), a valid tool, provided by the Agency for Healthcare Research and Quality (AHRQ) and to compare the results with AHRQ data. Methods: Administrators and staff (N=151) of six nursing homes in Seoul, Busan, Kyeonggi Province and Gyeongsangnam Province completed the survey in July, 2010. The data were analyzed using descriptive statistics, positive response rate, t-test, ANOVA, DUNCAN, Cronbach's ${\alpha}$. Results: The total mean (SD) positive response rate for patient safety culture was not significantly different from the AHRQ data. For composite levels, the results of 'handoffs' were significantly higher, and the results of 'feedback and communication about incidents' and 'nonpunitive responses to mistakes' were significantly lower than the AHRQ data. Conclusion: More effective strategies related to nonpunitive responses to mistakes and management activities for patient safety are needed to improve patient safety culture in nursing homes.

Purpose: The purpose of this study is to suggest a more efficient distance measure taking into account the relationship between categorical variables for categorical data cluster analysis. Methods: In this study, the association-based dissimilarity was employed to calculate the distance between two categorical data observations and the distance obtained from the association-based dissimilarity was applied to the PAM cluster algorithms to verify its effectiveness. The strength of association between two different categorical variables can be calculated using a mixture of dissimilarities between the conditional probability distributions of other categorical variables, given these two categorical values. In particular, this method is suitable for datasets whose categorical variables are highly correlated. Results: The simulation results using several real life data showed that the proposed distance which considered relationships among the categorical variables generally yielded better clustering performance than the Hamming distance. In addition, as the number of correlated variables was increasing, the difference in the performance of the two clustering methods based on different distance measures became statistically more significant. Conclusion: This study revealed that the adoption of the relationship between categorical variables using our proposed method positively affected the results of cluster analysis.

The Korean fisheries industry is a traditional business, the majority of which are small and medium-sized enterprises (SMEs). It has played an important role in the South Korean economies in the past several decades, but it currently faces the limitations of growth potential and profitability due to declining workforce, aging populations, deteriorating fishery environments, climate changes, and rapid changes in the global industrial ecosystem. Many studies have suggested solutions for the fisheries industry in macro perspective, but there are rarely any studies taking the strategic approaches for the problem. If it is possible for governments to support the companies that are likely to increase their value-added selectively, it will break through the current situation more effectively. This paper introduces a study on the selection method utilizing data envelopment analysis (DEA) to find SMEs with potentials to increase profits and growth. We suggest selecting SMEs with high management efficiency and ability to utilize intangible assets as the target companies. We also suggest policy objectives for SMEs in the domestic fisheries industry based on the results of DEA analysis and propose a data-based method for the policy decisions.

For approval of medical devices manufactured or imported, submission of technical documents as well as the application form is required. The manufacturer (or importer) should properly identify the raw materials the applied product is made of and the manufacturing processes the product undergoes before it is shipped in the application form. In the technical documents, scientific data to evaluate the efficacy, safety, and quality of the applied product that has been described in the application form should be provided. Therefore, identifying the raw materials that were used for the parts of the applied product and describing the physical and chemical characteristics of the raw materials are quite important and essential in ensuring the efficacy, safety, and quality of the applied product. To describe the physical and chemical characteristics of the raw materials correctively, the applicant is required to have broad knowledge in the scientific fields such as chemical, polymer, metal, and ceramic science and engineering. But most of the applicant are not experts in these fields, so that the description in the application form often includes wrong and improper descriptions. Thus, we developed a guideline which explains the raw materials for medical devices, show the their examples. The purpose of this description guideline is to help the applicant properly completing the "Raw materials or constituents and their volumes" part in the application form.

For the study of species diversity and distribution of Melanophyllum in Korea, M. eyrei and M. haematospermum were identified with unrecorded species and reported species, respectively. Their identification were confirmed based on macroand microscopic descriptions as well as ITS region sequence data. We give a Korean name 'Cheongheukjureumbeoseot' for M. eyrei and provided full description for M. haematospermum due to incomplete previous description.

To further our understanding of sugar accumulation in 'Shiranuhi' mandarin [(C. unshiu ${\times}$ C. sinensis) ${\times}$ C. reticulate], we investigated the patterns of sugar uptake in juice sacs exposed to different concentrations of sucrose, fructose and glucose in vitro. Data was also collected on the change in weight and shape of the in vitro juice sacs over time. Soluble solids content, sugar content and acidity content were highest at 20% sucrose, fructose and glucose solution content; while fructose content was highest at 5% sucrose concentration. Furthermore, the juice sac's fresh weight was highest at 5% sucrose and lowest at 20% fructose content. The shape of the juice sacs also differed in different sugar concentration and type. Overall, sucrose, fructose and glucose content in juice sacs increased with the sugar concentration. These results suggest that sugar translocation into juice sacs is actively induced by high sugar concentration in the medium. Thus, it can be concluded that sugar and acid accumulation in juice sacs increased with sugar concentration in vitro culture.

In the present study, we carried out quantitative analysis of chrysin and pinocembrin in Korean propolis by ultra performance liquid chromatography (UPLC) equipped with diode array detector. The separation was done using BEH C18 ($2.1{\times}50mm$, $1.7{\mu}m$) column with a mobile phase consisting of MeCN and 0.1% $H_3PO_4$ at 280 nm. The chromatographic method was validated for specificity, limit of detection, limit of quantification, linearity, precision, and accuracy. A quantitative analysis exhibited that the contents of the two compounds in Korean propolis collected from 8 inland areas except Jeju-do ranged from 3.1-46.0 mg/g. These results will be valuable as basic data for standardization of Korean propolis.

In April 2014, seedlings of Fallopia multiflora showing wilt symptom were first found at a greenhouse in Punggi-eup, Yeongju-si, Korea. A Fusarium-like fungus was isolated from the wilted plant and it was identified as Fusarium oxysporum based on morphological characteristics and nucleotide sequence data of translation elongation factor 1-${\alpha}$. The fungus isolated from the diseased plant was revealed to be pathogenic to the host plant through pathogenicity tests, and the reisolation of the pathogen confirmed Koch's postulates. This is the first report of Fusarium wilt occurring on Fallopia multiflora in the world.
