Purpose: This study aimed to identify attitudes toward advance directives (ADs) among female cancer patients and factors related to ADs. Methods: The study was conducted at a university hospital in Seoul from September 19, 2020, to January 20, 2021. The participants were 153 patients diagnosed with gynecological cancer or breast cancer. Data were collected using questionnaires and included general characteristics, disease- and AD-related characteristics, knowledge and attitudes about ADs, and attitudes about dignified death. Data were analyzed using the t-test, analysis of variance, and multiple regression analysis. Results: Only 2% of the participants completed ADs. The mean score for attitudes toward ADs was 3.30, indicating a positive knowledge and attitude toward dignified death. The factors related to attitudes toward ADs were attitudes toward dignified death (𝛽=0.25, P=0.001), experience discussing life-sustaining treatment (𝛽=0.17, P=0.037), preferred time to have a consultation about ADs (𝛽=0.19, P=0.046), intention to write ADs (𝛽=0.15, P=0.038), and Eastern Cooperative Oncology Group Performance Status (𝛽=-0.37, P<0.001). The explanatory power of these variables for attitudes toward ADs was 38.5%. Conclusion: Overall, patients preferred to have a consultation about ADs when they were still active, mentally healthy, and able to make decisions. Education about ADs should be provided to patients on the first day of hospitalization for chemotherapy or while awaiting treatment in an outpatient setting so patients can write ADs and discuss them with family and friends.

Purpose: The purpose of this study was to promote awareness of the need for advance directives (ADs) and to provide baseline data for the development of a nurse training program about ADs. Methods: Nurses at eight long-term care hospitals in Busan and South Gyeongsang Province (N=143) were recruited using the random sampling method from December 2018 to January 2019. Data were obtained using a structured self-reported questionnaire to assess their knowledge, experience, and attitudes regarding ADs. Data were analyzed in SPSS 22.0 using descriptive statistics, the t-test, analysis of variance, the Scheffé test, Pearson's correlation coefficient, and stepwise multiple regression analysis. Results: The mean scores were 7.79±1.39 points for knowledge, 1.92±2.00 points for experience, and 2.80±0.24 points for attitudes regarding ADs. Knowledge and experience (r=0.32, P<0.001) had a positive correlation with knowledge and attitudes (r=0.17, P=0.39). Conclusion: According to the results, nurses generally had a high level of knowledge regarding ADs, which resulted in a positive attitude toward ADs. However, they had little experience with ADs. Therefore, nurses' must develop both direct and indirect experience with ADs using a practical training program to strengthen their clinical competency regarding ADs.

Purpose: Advance directives (ADs) are legal documents that outline a person's preferences or decisions regarding end-of-life care ahead of time. In Korea, there is insufficient awareness and knowledge about ADs among patients undergoing hemodialysis. This study explored the relationship between perceptions of a good death, knowledge about ADs, and attitudes toward ADs in this patient population. Methods: This cross-sectional survey enrolled 119 hemodialysis patients from a secondary hospital in 2021. The participants completed a self-administered questionnaire, and the data were analyzed using the t-test, analysis of variance, Pearson correlation coefficients, Spearman rank correlation coefficients, and multiple regression analysis. Results: The average score for perceptions of a good death among hemodialysis patients was 2.80 out of 4, with clinical symptoms identified as the most critical factor. The average scores for knowledge about ADs and attitudes toward ADs were 5.69 out of 9 and 2.79 out of 4, respectively. There was a positive correlation between perceptions of a good death and attitudes toward ADs (r=0.34, P<0.001), as well as between knowledge about Ads and attitudes toward ADs (r=0.19, P=0.037). Factors influencing attitudes toward Ads included employment status (β=0.22, P=0.011), education level (β=0.22, P=0.013), and perceptions of a good death (β=0.29, P=0.001), which accounted for 24.8% of the variance in attitudes toward ADs. Conclusion: A positive perception of a good death among patients undergoing hemodialysis was associated with a positive attitude toward ADs. Educational programs are needed to improve individuals' understanding of a good death and encourage the development of end-of-life care plans.

AC PDP의 ADS 추동 방식은 구동 방법이 간단하여 구현하기가 용이할 뿐만 아니라 가장 안정적인 구동 방식으로 널리 사용되고 있다 [1]. 그러나 ADS 구동 방식은 주사선의 수가 늘어남에 따라 어드레싱에 필요한 시간이 증가하게 되고 유지방전 구간에 할애할 시간이 상대적으로 감소하게 되어 휘도가 저하되게 되는 문제점을 갖고 있다. 이러한 문제를 해결하기 위하여 어드레싱 시간을 최소화하기 위한 고속 어드레싱 기술에 대한 연구가 계속하여 진행되고 있다 [2-10]. 본 논문에서는 고속 구동 시에 나타나는 불안정한 어드레싱으로 인한 화질의 저하문제를 해결하기 위한 개선된 ADS 구동파형을 제시한다. 초기화 구간의 Reset 파형은 어드레싱 추간의 특성에 중요한 영향을 미치게 되는데, Reset 구간에서 생성된 벽전하를 어드레싱 방전구간 동안 지속적으로 유지되게 함으로서 어드레싱 방전전압을 줄이고 안정적인 어드레싱이 유지될 수 있도록 하였다. 본 논문에서는 Priming Effect의 영향이 급격히 감소하는 80us 이후, 벽전하의 생성을 돕는 Wall Charge Acceleration Pulse를 적용함으로서 불안정한 어드레싱 문제를 해결할 수 있는 방법을 제시하였고 휘도의 불균등화로 인한 화질 저하의 문제를 해결하였다.

The annular denuder system(ADS) was used to determine characteristics of acidic air pollutants and $PM_{2.5}$ species in Seoul-metropolitan areas. All measurements were done simultaneously in downtown(Kwanghwamun, Mullae, Chamshil, Ssangmun dongs) and outskirts(Puch n, Kuri cities) during four seasons. The samples were analyzed using ion chromatography for gas-phase matters(HCl, $HNO_2$, $HNO_3$ and $SO^2$) and particulate phase matters($Cl^-$, $NO^{2-}$, $NO_3^-$, $SO_4^{2-}$, $Na^+$, $NH_4^-$ and $Ca^{2+}$) and was measured fine particles($PM_{2.5}$). The seasonal mean concentrations of HCl, HNO2, HNO3 and SO2 in downtown and outskirt areas were very similar. All chemical species monitored from this study showed seasonal variations. Nitric acid(HNO3) and Nitrous acid(HNO2) were showed higher concentrations during the summer. $PM_{2.5}$, $SO_4^{2-}$, $NH_4^-$, $NO_3^-$ and $Cl^-$ in the particulate phase matters were higher levels during the winter months. The concentrations of these components were 54.8, 3.82, 2.49, 1.80 and 1.02$\mu\textrm{g}$/㎥, respectively.

Mobile phone makers compete for market shares through domination in media advertisements. These include domination of advertisements (Ads) in TV and the internet. However, the abundance and complexity of the competitions of Ads in TV does not guarantee advertising success which can influence consumers' emotion and the purchase intention towards the brand. This research analyses the case of a directional model on Attitude-towards-the-Ad model as a baseline into a new proposed correlation models (MacKenzie, Scott, &Lutz, 1989). The survey targets the involvements of Asian smartphone owners' attitude on advertisements, brands and purchase intentions. CFA (Confirmatory factor Analysis) was used in the research experiments, including hypothesis testing, the outcome of model fit which revealed significant levels and were successful. The study revealed that all three paths have consistently high coefficient paths (Attitude to Ads - Attitude to Brands - Purchase Intention), showing significant value of (${\beta}$=>.80), which supported each correlation factors. Therefore, this structural model, could set standards for creative managers and advertising teams to improve the brands visibility and build strong influences on attitudes in advertisements and improve purchase intentions.

Purpose : The purpose of this study was to identify the factors influencing the general hospital nurses' confidence about the advance directives (ADs). Methods : This is a descriptive cross-sectional study. A total of 105 nurses were asked questions about characteristics, knowledge, attitude, learning needs, and confidence the about ADs, using structured questionnaires. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Results : The mean scores of knowledge were 7.26±1.47; attitude, 2.80±0.31; learning needs, 4.22±0.62; and confidence, 2.57±0.74. It was observed that knowledge had significant correlations with attitude (r=.43, p<.001), learning needs (r=.29, p=.003), and confidence (r=.40, p<.001), and attitude had significant correlations with learning needs (r=.31, p=.001) and confidence (r=.45, p<.001). Using multiple regression analysis, it was found that confidence was significantly influenced by knowledge (β=.27, p=.007), attitude (β=.21, p=.043), and experience of nursing or counseling a patient who wrote ADs (β=-.19, p=.046). The explanatory power of this model was 37.9% (F=5.16, p<.001, R²=.379). Conclusions : These findings suggest the need to develop a program to enhance nurses' knowledge, positive attitude, and experience of nursing or counseling a patient who wrote ADs.
