Purpose: The purpose of this study was cross-mapping unique nursing statements which were identified in the nursing records of patients with six most common cancers in Korea with the standardized nursing languages of NANDA, NIC, NOC and ICNP. Method: The subjects were 72 nursing records which covered 1,502 admission days from August 1, 2003 to June 30, 2003. They were the records of the patients of six most common cancers who were treated at the six 3rd level general hospitals in Busan and Daegu. The unique nursing statements were identified by dividing the statements from the nursing records into the single statements according to their meanings. For cross-mapping, identified unique nursing statements were classified as 'Data(D)' for the subjective, objective data of the patients and the other data such as treatment, admission, discharge, and residence of patient, 'Problem(P)' for nursing problem or diagnosis defined by the nurse's decision, 'Intervention(I)' for nursing intervention for problem solving, and 'Outcome(O)' for patient reaction and results of the provided nursing interventions. Unique nursing statements classified to D, P, I, O were cross-napped by using Microsoft Excel 2000. The statements of D were cross-mapped with ICNP Nursing phenomena, P with NANDA nursing diagnosis and ICNP nursing phenomena, I with NIC and ICNP nursing intervention, and O with NOC and ICNP nursing phenomena Result: The results of this study were as follows. 1. Number of unique nursing statements were 506 in the records of lung cancer patients (18.12%), 480 in stomach cancer(17.19%), 458 in liver cancer(16.40%), 456 in colon cancer (16.33), 457 in breast cancer (16.36%) and 436 in cervix cancer (15.60%). 2. The range of percentage of cross-mapped unique nursing statements with the standardized nursing languages were as follows: P with NANDA nursing diagnosis $87.50{\sim}100%$, I with NIC $59.72{\sim}74.43$, O with NOC $61.05{\sim}72.64%$, and D, P, I and O with ICNP $60.92{\sim}69.95%$. 3. Number of the standardized nursing languages identified in this study were 21(12.66%) from 155 NANDA nursing diagnosis, 76(15.64%) from 486 NIC Nursing interventions, 54(17.47%) from 260 NOC nursing outcomes, and 343(13.03%) from ICNP 2,634. Conclusions: By the results of this study, NANDA, NIC, NOC and ICNP were found that they can be used as the language systems for nursing record and nursing information system for cancer patients. But, further study on the unique nursing statements which were not cross-mapped with the standardized nursing language systems will be necessary.

The purpose of this study was to analyze myosin heavy chain (MHC) isoforms in bovine longissimus thoracis (LT) muscle by liquid chromatography (LC) and mass spectrometry (MS). LT muscles taken from Hanwoo (Korean native cattle) steer (n=3) used to separate myosin bands by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The peptide queries were obtained from the myosin bands by LC-MS/MS analysis following in-gel digestion with trypsin. A total of 33 and 43 queries were identified as common and unique peptides, respectively, of MHC isoforms (individual ions scores >43 indicate identity or extensive homology, p<0.05). MHC-1 (IIx), -2 (IIa), -4 (IIb), and -7 (slow/I) were identified based on the Mowse score (5118, 3951, 2526, and 2541 for MHC-1, -2, -4, and -7, respectively). However, more analysis is needed to confirm the expression of MHC-4 in bovine LT muscle because any query identified as a unique peptide of MHC-4 was not found. The queries that were identified as unique peptides could be used as peptide markers to confirm MHC-1 (14 queries), -2 (8 queries), and -7 (21 queries) in bovine LT muscle; no query identified as a unique peptide of MHC-4 was found. LC-MS/MS analysis is a useful approach to study MHC isoforms at the protein level.

Biological systems offer unique principles for the design and fabrication of engineering platforms (i.e., popularly known as "Biomimetics") for various applications in many fields. For example, the lotus leaves exhibit unique surfaces consisting of evenly distributed micro and nanostructures. These unique surfaces of lotus leaves have the ability of superhydrophobic property to avoid getting wet by the surrounding water (i.e., Lotus effect). Inspired by the surface topographies of lotus leaves, the artificial superhydrophobic surfaces were developed using various micro- and nanoengineering. Here, we propose new platforms that can control hydrophilic and hydrophobic property of surfaces by mimicking micro- and nanosurfaces of various natural leaves such as common camellia, hosta plantaginea, and lotus. Using capillary force lithography technology and polymers in combination with biomimetic design principle, the unique micro- and nanostructures mimicking natural surfaces of common camellia, hosta plantaginea, and lotus were designed and fabricated. We also demonstrated that the replicated polymeric surfaces had different hydrophilic and hydrophobic properties according to the mimicking the natural leaf surfaces, which could be used as a simple, but powerful methodology for design and fabrication of controlled hydrophilic and hydrophobic platforms for various applications in the field of agriculture and biological engineering.

This study investigated consumers' clothing expense, consumer innovativeness and perceived risk to the channel type they frequently purchase fashion products and compared the relationship between the variables. A survey of male and female college students was conducted and 367 responses were analyzed using descriptive statistics, chi-square analysis, two-way ANOVA, factor analysis, reliability analysis, and correlations. Female consumer clothing expenses were high compared to male consumers, and clothing expenses of consumers using department stores and independent banded stores were high compared to those using internet shopping malls. The sub-dimensions of consumer innovativeness were determined as adventure-oriented, unique-oriented, and change-oriented, and female consumers have characteristics more unique-oriented and change-oriented. In the case of female respondents, unique-oriented innovativeness was highest for department store customers, while the male customer of non-branded stores showed the highest unique-oriented innovativeness. Perceived risk indicated the highest score from the customers of internet shopping mall. Department stores were recognized as reliable by female department store customers. Clothing expenses and consumer innovativeness dimensions showed significantly positive correlations; in addition, the relation between clothing expense and perceived risks were significantly negative. Consumer innovativeness and perceived risks have positive relations.

This paper investigates the autonomous ground vehicle (AGV) localization filter design problem under GNSS-denied environments. It is assumed that the given landmarks do not have unique features due to the lack of a prior knowledge on them. For such case, the AGV may have difficulties in distinguishing the position measurement of the detected landmark from those of other landmarks with the same feature, hence the conventional localization filters are not applicable. To resolve this technical issue, the localization filter design problem is formulated as a special form of the data association determining whether the detected feature is actually originated from which landmark. The measurement hypotheses generated by landmarks with the same feature are evaluated by the nearest neighbor data association scheme to reduce the computational burden. The position measurement corresponding to the landmark with the most probable hypothesis is used for localization filter. Through the experiments in real-driving condition, it is shown that the proposed method provides satisfactory localization performance in spite of using non-unique landmarks.

The Jing is a traditional Korean percussion instrument which plays a major role in Korean folk music. The distingishing feature of this instrument is its unique, long lasting low tone timbre. In this paper, we investigated the vibro-acoustic characteristics of the Jing. Our attention was focused mainly on findings out the physical variables that determine its unique sound. By understanding the way in which the Jing is manufactured, we were able to realize that the unique manufacturing and especially the tuning process by expert craftsman is responsible for the peculiar timbre the Jing produces. The experimental methods implemented to analyzer the Jing were planar acoustic holography and direct measurements by accelerometers. The results from the holographic method and the direct measurements were in good agreement. It turned out that unlike most percussion instruments which have inharmonic partials, the Jing has harmonic partials which are responsible for its unique low-tone timbre. From the holographic representations of the modes, it is clear that the antinodes are located in the center of the Jing which is coincident with the typical striking location. In addition, intensity maps were constructed so that the specific acoustic energy flow can be visualized. It was also interesting to see the the circulation of energy intensity which corresponds to the rotating mode of the Jing.
