The color of apparel products have a close relationship with the face skin colors of consumers. In order to extract the favorable colors which flatter to consumer's face skin colors, this study was carried our to classify the face skin colors of Korean females. The criteria that select new subjects who have the classified face skin colors have to be decided. With color spectrometer, JX-777, face skin colors of subjects were measured and classified into three clusters that had similar hue, value and chroma with Munsell Color System. Sample size was 324 Korean females and other new 10 college girls. Data were analyzed by K-means cluster analysis, ANOVA, Duncan multiple range test, Stepwise discriminant analysis using SPSS Win. 12. Findings were as follows: 1. 324 subjects who have YR colors were clustered into 3 face skin color groups. 2. Discriminant variables of face skin colors were 5 variables : b value of cheek, V value of forehead, L value of cheek, C value of forehead and H value of cheek by the standardized canonical discriminant function coefficient 1. 3. Hit ratio of type 1 was $96.8\%$, of type 2 was $94.9\%$, of type 3 was $100.0\%$ and mean of hit ratio was $96.9\%$ by canonical discriminant function of 5 variables. 4. With the unstandardized canonical discriminant function coefficient and constant, canonical discriminant function equation 1 and 2 were calculated.

This paper studies mismatched scalar quantization of a generalized gamma source by a quantizer that is optimally (in the mean square error sense) designed for another generalized gamma source. Specifically, it considers variance-mismatched quantization which occurs when the variance of the source to be quantized differs from tat of the designed-for source. The main result is the two distortion formulas derived from Bennett's integral. The first formula is an approximation expression that uses the outermost threshold of an optimum scalar quantizer, and the second formula, in turn, uses an approximation formula for this outermost threshold. Numerical results are obtained for Laplacian sources, which are example of a generalized gamma source, and comparisons are made between actual mismatched distortions and the two formulas. These numerical results show that the two formulas become more accurate, as the number of quantization points gets larger and the ratio of the source variance to that of the designed-for source gets bigger. For example, the formulas are within 2~4% of the actual distortion for approximately 64 quantization points or more. In conclusion, the proposed approximation formulas are considered to have contribution as closed formulas and for their accuracy.

Nodular fasciitis is a benign fibroblastic proliferation rarely reported in the breast. We report the case of a 55-year-old woman who presented with imaging findings that resembled a malignancy. Mammography revealed an isodense nodule with partially indistinct margin in the right breast, showing the abnormality score 75% on artificial intelligence. Ultrasonography revealed an oval hypoechoic nodule with microlobulated margin, echogenic halo, increased blood flow, and soft elasticity. After core needle biopsy and excision, nodular fasciitis was diagnosed. Although nodular fasciitis of the breast is rare, it may mimic malignancy; therefore, it should be considered as a differential diagnosis to prevent unnecessary intervention.

The purpose of this study was to examine the perception of abortion and suicide for 115 paramedic students in 2016. The questionnaire consisted of perception of abortion(8items), the perception of suicide(58items), related 6items of the abortion and related 2 items of the suicide. The collected data were analyzed through t-test, Chi-squared test and ANOVA, using SPSS 21.0. As a result, the total perception score against abortion was $20.57{\pm}4.12$ and the total score of suicide perception was $-14.16{\pm}15.76$. The most answer was that pregnant women were abortion decision makers in both male and female students, and abortions were the highest when they might be unwanted pregnancies. The group who had thought about suicide was higher of perceptions of suicide than the group who did not. The female students who had suicide attempt or suicide experience of close acquaintances showed higher suicide perception score than those who did not. Therefore, A bio-ethics education curriculum should be prepared to establish ethics that respects life for future paramedic students who must make decisions at the boundary between death and life. It is necessary to raise the level of positive suicide perceptions through continuing counseling and education focusing on students who have experienced suicide by family members or acquaintances.

This study aims to develop the diagnostic evaluation method of the riverine ecobelt for construction, conservation, and maintenance of the riverine ecobelt. The value indices in the proposed evaluation method are composed of total 5 fields and 19 elements. The 5 fields are flood control, environmental function, growth of plants, ecobelt function, and restoration potential. Flood control field is composed of total 3 elements such as length, width, and density of green area. Environmental function field is composed of 4 elements such as park use, landscape boundary and edge, microclimate control, non-point pollution control. Growth of plants field is composed of 6 elements such as species composition, forest height, stratum structure, vine plants, plant vitality, and succession of plants. Ecobelt function field is composed of 4 elements such as longitudinal connectivity, lateral connectivity, in-stream forest or habitat, roads on bank top. Restoration potential field is composed of 2 elements such as landform and land use of the immediate vicinity. The score system ranging 1~4 was adopted. The weighting parameters of elements were unified with each other. The final grade system ranging 1~5(1: very good~5: very bad) was adopted, and the final grade was evaluated by the mean values of each field. According to the test application of the diagnostic evaluation method of the riverine ecobelt, the final grades showed effectively the real condition of each site.

Purpose: To evaluate the results of meniscal repair and partial meniscectomy of lateral meniscus injury associated with tibial plateau fracture. Materials and Methods: Between February 1993 and August 2004, 24 cases (23 patients) of lateral meniscus tear with tibial plateau fracture were evaluated retrospectively. The most frequent type of tear was the longitudinal tear of the meniscocapsular junction (14 cases, 66.7%). All fractures were reduced under the control of arthroscopic and image intensifier. Arthroscopic repair of the longitudinal tear of the lateral meniscus or arthroscopic partial meniscectomy was performed. The final results were evaluated with the Ikeuchi criteria and Lysholm score. Results: At the final follow-up, the outcome was excellent in 12 cases (85.7%), good in 1 case (7.1%) and fair in 1 case (7.1%) among 14 cases of meniscal repair, and the excellent in 4 cases (66.7%) and good in 2 cases (33.3%) among 6 cases of partial meniscectomy according to the Ikeuchi criteria, There was a significant improvement of Lysholm score after surgery, 92.3 postoperatively compared with 56.6 preoperatively (p<0.0001, paired t-test). Conclusion: The fracture of the lateral tibial plateau did not seem to affect on the healing of the meniscus repair and partial meniscectomy.

This was an investigative study to identify the role expectations for clinical research related tasks that ward nurses can participate in and the awareness of cooperation between ward nurses and clinical research nurses (CRNs) and the obstacles for the same. The subjects were 66 ward nurses and 65 CRNs. The data were analyzed using descriptive statistics, the two-sample t-test, and the 𝑥² test on SAS 9.3. As a result of this study, 4.56±0.41 ward nurses and 3.83±0.60 CRNs were found to have high role expectations of each other and statistically significant role expectations for ward nurses (p<.001). Significant differences were seen in the five categories of cooperation recognition between the two groups. Among the factors for cooperative disabilities, excessive work and lack of awareness of clinical research were ranked high. High role expectation becomes an element of role conflict. To organize the role of ward nurses and clinical research nurses in the new clinical research nursing work, procedures, establishing of effective practices, and the proper operation of an official system are expected to be necessary. To promote cooperation between the two groups, a culture of mutual trust and cooperation should be formed to enable each group to think of the other as partners and to recognize their expertise.

In this study, with arbitrary reference points on the water, photogrammetry accuracy analysis was conducted using unmanned aerial vehicle(UAV). A small reservoir is a research area, and twenty buoys were used as arbitrary reference points. Errors of location coordinate were identified with control of amounts of used reference points. cases are categorized by index scores per photos. Accuracy of X is 0.141m~0.166m and accuracy of Y is 0.136m~0.241m. Considering that allowable error for the maritime boundary survey is ${\pm}2m$, it is possible to get the accuracy data available for the photogrammetry of UAV using an reference point. In addition, the coefficient of correlation between the number of reference points per unit and number of buoys used as reference point and the ratio of the reference point per square measure, and percentage of buoys used as reference point and the coefficient of x and y were performed. Each element, x, and y showed a strong correlation and the coefficient of number of buoys used as reference point was irrelevant. The results of this correlation analysis can be analyzed that the number of reference points used in each picture is greater than the actual number of reference points used in location accuracy.
