  • Purpose: Clinical nurses are the ideal health care providers to advocate for vulnerable and underserved populations such as people with disability. This study aimed to understand factors influencing nursing advocacy for people with disability among clinical nurses. Methods: The subjects of this study were 186 clinical nurses who were working in three hospitals in B and D cities. Self-report questionnaires were used to collect the data. Data were analyzed using IBM SPSS Statistics 25 with descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results: Clinical experience and esthetical nursing competency have positive correlations with nursing advocacy, and optimism-human rights has a negative correlation with nursing advocacy. Factors influencing nursing advocacy for people with disability were identified as patient directivity (β=0.36, p=.001), optimism-human rights (β=-0.18, p=.008) and clinical experience (≥10) (β=0.14, p=.036). The final model consisting of these factors explained 19% of the variance of nursing advocacy (F=14.99, p=.001). Conclusion: The findings of this study indicate the importance of developing and implementing nursing interventions that can improve patient directivity and optimism-human rights toward people with disability among clinical nurses. These nursing advocacy interventions can be provided as part of continuing education as well as the nursing curriculum.

  • 분말야금된 소결체의 가장 큰 특징 중의 하나는 피할 수 없는 소결체의 기공이다. 이러한 기공이 기계적 특성에 미치는 영향에 관해서는 많은 연구가 오래 전부터 진행되었었다. 그러나 기존의 연구는 거의 대부분 일반 분말야금에 의한 것이고 분말사출성형된 소결체의 기공율과 기계적 특성 광계는 거의 연구가 이루어 지지 않았다. 본 연구에서는 기공율의 조절이 용이한 분말사출성형 공정을 이용하여 소결 초기부터 완전 치밀화에 가까운 조직까지 다양한 소경율의 시편을 만들어 기계적 특성에 미치는 순수기공의 영향은 조사하기 위해 다음과 같이 조사하고자 하였다. 사출성형에 사용된 재료는 고강도 이며 내식성이 뛰어난 17-4 PH STS이고 평균 입경은 10mm였다. 열분해와 소결은 수소 분위기에서 행하였으며 소결온도는 900~$1350^{\circ}C$였다. 연구수행을 통해 다음과 같은 결론을 얻었다. 1. 기공율과 기계적 특성의 관계는 닫힌 기공이 지배하는 고밀도 영역과 열린 기공이 지배하는 저밀도 영역을 분리하여 해석해야한다. 2. 저밀도 영역에서의 기공율과 강도의 관계는 넥 성장에 따른 load bearing area의 증가로 나타낼 수 있고 아래와 같다. $\frac{\delta}{\delta_o}=1-\frac{P}{P_i}$ 3. 고밀도 영역에서의 기공율과 강도의 관계는 소결 현상과 초기 충진율을 고려한 ideal pore모델을 도입하였고 아래와 같이 나타났다. $\frac{\delta}{\delta_o}=1-1.95(P_i\;{\cdot}\;P)^{2/3}$

  • Despite the abundance of seaweeds from Ulleungdo Island, genetic diversity and distribution of edible brown algae from the island remain unstudied. We analyzed mitochondrial cox3 sequences from 86 specimens collected in the island and from the nearby Korean Peninsula. Our cox3 phylogeny for the first time confirmed the occurrence of fives species from Ulleungdo Island; Petalonia binghamiae, P. fascia, Planosiphon zosterifolius, and two cryptic species previously identified as Scytosiphon lomentaria. P. binghamiae was relatively homogeneous with three haplotypes. P. fascia comprised four haplotypes, which were grouped into two genetic lineages. S. lomentaria was heterogeneous with nine haplotypes and was divided into two cryptic species; one species clustered with taxa from cold waters while the other clustered with taxa from temperate and cold waters. Low genetic diversity in P. binghamiae while high genetic diversity in S. lomentaria from Ulleungdo Island are comparable to patterns observed from other species from the Korean peninsula. Ulleungdo Island, although small in size, is an ideal field laboratory to investigate genetic diversity and distributions of economic marine algae.

  • In orthognathic surgery to obtain proper functional and esthetic form after skeletal discrepancy treatment, precise diagnosis and treatment plan are essential. Especially in two jaw surgeries that have serious upper and lower jaw problems, maxilla and mandible are arranged in three dimensions. Based on the maxillary rearrangement, mandibular sagittal and transverse positions are determined, and thus new occlusal plane is established. The object of this study is to evaluate the stability of the indiviual ideal occlusal plane based on the architectural and structural craniofacial analysis of Delaires. The subjects of this study were 48 patients who underwent two jaw surgeries, and they were equally divided into two groups, A and B. A group was operated with ideal occlusal plane and B group was not. Two groups were compared at the preoperative, immediate postoperative (average 4.3days), and long-term postoperative (average 1.3years) lateral cephalometric radiographs. The following results were obtained: 1. ANS was lower than that of PNS for both A and B after the surgery. That is, maxilla and mandible are rotated in posterior and superior direction. 2. Significances were found between $T_2$ and $T_3$ for both A and B are HRP-Me at vortical measurements, articular angle(p<0.01), gonial angle(p<0.01), and Mn. plane angle(p<0.05) at angular measurement. Mn. plane angle is increased at HRP-Me is decreased for both A and B. 3. There is no significance in skeletal stability aster the surgery between group A and B. 4. Horizontal movements of B and Pog by surgery have statistically significant inverse correlations with horizontal relapse of B and Pog, and vertical relapse of PNS, as well as Mn. Plane angle, and gonial angle after the surgery.

  • In the shape optimal design based on h-version of FEM, the ideal mesh for the initial geometry most probably will not be suitable for the final analysis. Thus, it is necessary to remesh the geometry of the model at each stage of optimization. However, the p-version of FEM appears to be a very attractive alternative for use in shape optimization. The main advantages are as follows; firstly, the elements are not sensitive to distortion for interpolation polynomials of order $p{\geq}3$; secondly, even singular problems can be solved more efficiently with p-version than with the h-version by proper mesh design; thirdly, the initial mesh design are identical. The 2-D p-version model for shape optimization is presented on the basis of Bezier's curve fitting, gradient projection method, and integrals of Legendre polynomials. The numerical results are performed by p-version software RASNA.

  • This study examined the relationships among body perception, anxiety, psychological flexibility, and abnormal eating habits of college students. Data was collected through a self reported structured questionnaire from 289 Korean college students using convenient sampling methods from April 20 to June 30, 2013. Multiple linear regression revealed the subjective body perception (${\beta}$=0.28, p<.001), ideal body image (${\beta}$=-0.15, p=.004), anxiety (${\beta}$=0.21, p<.001), and psychological flexibility (${\beta}$=-0.13, p=.032) to be significant predictors of abnormal eating habits of college students. These variables accounted for 26% of abnormal eating habits (F=17.42, p<.001). Therefore, as a strategy for reducing abnormal eating habits, therapeutic nursing intervention will be needed to improve the psychological flexibility and control anxiety as well as correct the distorted body perception.

  • 최근에 감지막의 pH 감지특성을 평가하기 위해 electrolyte insulator semiconductor (EIS) 구조가 유용하게 이용되고 있다. EIS는 CMOS공정과 호환이 가능하고 구조가 간단하며 pH 변화에 반응속도가 빠르다는 장점을 가지고 있다. EIS 구조를 갖는 pH 센서의 동작 메커니즘은 pH 용액의 수소이온이 감지막의 표면에서 표면전위를 변화시키는 것에 기인한다. pH 감지막으로는 높은 유전율과 안정성이 뛰어난 high-k 물질이 많이 연구되고 있다. 그 중 high-k 물질인 ZrO2은 낮은 열전도도, 산성에서 알칼리성 영역까지의 넓은 화학안정성을 가지며 낮은 열 팽창성, 높은 유전상수 등 우수한 특성을 가지고 있다. 본 실험은 SiO2/ZrO2를 적층한 EIS 소자를 제작하여 열처리에 따른 전기적 특성과 pH 감지 특성을 평가해 보았다. EIS 적층막으로 사용된 SiO2는 실리콘과 high-k 감지막 사이의 계면상태를 양호하게 유지시키기 위한 완충막으로 성장되었다. 후속열처리는 rapid thermal annealing (RTA) 시스템을 이용하여 750$^{\circ}C$, 850$^{\circ}C$, 950$^{\circ}C$로 H2/N2 분위기에서 30초 동안 실시하였다. RTA 열처리 온도가 증가할수록 높은 pH 감지특성이 보였으며 hysteresis 현상과 drift 효과와 같은 non ideal 효과에 강한 immunity가 있는 것을 확인하였다. 결론적으로 SiO2/ZrO2 적층구조를 갖는 EIS는 RTA 950$^{\circ}C$ 열처리를 실시하였을 때 우수한 EIS pH 센서를 제작할 수 있을 것으로 기대된다.

  • The risks of the metabolic syndrome (MS) is known to be related to the dietary behavior. The objective of this study is to evaluate the association between the relative risks of MS and the dietary habit and to provide the ideal dietary habits for prevention of chronic disease of the middle-aged. Healthy subjects aged 40-64 years (male n=122, female n=173) were recruited throughout Seoul area. MS was defined according to NCEP-ATP III criteria except central obesity, and Asia-Pacific Area criteria for central obesity (2000) was adapted. Subjects were stratified into 3 groups according to the number of total risk factors:'MS group' was defined as the subjects who have three or more risk factors, 'Risk group' was defined as ones to have one or two risk factors, and 'Healthy group' defined as ones with no risk factor. In this study, 'Health group' comprised of $40.7\%$, the percentage of 'Risk group' was $49.0\%$, and the 'MS group' was $9.5\%$ of the total subjects. The MS incidence was associated with low education (p<0.001), low economic status (p<0.05), and low self-assessed health recognition (p<0.05). The risk of MS increased with adverse life styles such as cigarette smoking (p<0.05), irregular meal time (p<0.05), skipping lunch (p<0.05), low interests in balanced diet (p<0.05), and higher salt intake (p<0.01). Healthy group self-evaluated nutritional knowledge more highly (p<0.05) and scored higher nutritional knowledge (p<0.001). However, there was no difference in overall nutritional behavior among the three groups, which implies that nutritional education method should be developed for the subjects to practice their teaming efficiently.

  • This experiment was conducted to examine the ideal condition for multiple colors dyeing of cut rose, 'Akito'. Four different colors of dye were applied to make multiple flower colors in cut rose by absorption method. Acidic condition around pH 3.5 showed the fastest absorption speed in all four colors. There is no difference at each pH levels, at part of leaves dyeing, it is more affected colors rather than pH levels in purple and blue colors. From vary concentration of each dyes, $10g{\cdot}L^{-1}$ concentration of dyeing solution gave the best color definition. But it's not significant and result was different by each color in a same concentration. 10 minutes of dyeing performed pastel color and 30 minutes performed the best color definition, but the 30 minutes treatment accompanied with significant dyeing on the leaves also. As a result of this experiment, optimum condition for dyeing cut rose, 'Akito' requires pH 3.5, $5-10g{\cdot}L^{-1}$ of dye concentration and 10-30 minutes treatment.
