본 연구에서는 암생존자의 스트레스가 우울과 삶의 질에 영향을 미치는 과정에 외상 후 성장이 조절효과를 나타내는지 확인하고자 하였다. 이를 위해 서울시, 경기도, 충청도, 전라도에 거주하는 암생존자 173명을 대상으로 설문조사를 실시하였고 응답한 자료로 위계적 회귀분석을 실시하였다. 분석 결과 첫째, 외상 후 성장은 스트레스와 상호작용하여 암생존자의 우울 및 삶의 질에 영향을 미쳤다. 즉 스트레스 수준이 높더라도 외상 후 성장이 높으면 외상 후 성장이 낮을 때보다도 우울 수준이 더 낮고, 삶의 질 수준이 더 높은 것으로 나타났다. 둘째, 외상 후 성장은 삶의 질의 하위요인 중 정서적 및 기능적 삶의 질에서만 조절효과를 나타냈다. 본 연구결과를 바탕으로 암생존자의 우울 감소와 삶의 질 증진을 위해서는 외상 후 성장을 높이는 교육 및 상담적 개입이 필요함을 논의하였다.

Purpose The purpose of this study is to examine the review of previous studies based on audiobooks, 1) using the IPA method, we examine the quality of audiobooks that listeners perceive as important and the quality of preferred audiobooks, 2) improvement directions for activating audio content and audiobook platform, to seek ways to establish strategic plans for the audiobook market. Design/methodology/approach This study conducted and experiment using three factors(usability, information and interaction) used in web service quality(WebQual). Usability consists of the availability of time, such as the use of audiobooks for hobbies and the ease of search. Information consists of the trends of the times, topics of converation and the latest trends. Interaction consists of the proportion and depth of celebrities. After that, grid analysis was performed using the traditional IPA method and the revised IPA method. It was judged that identifying and analyzing the preference for service provision and new content was more valuable than the Performance used in the existing method. Findings According to the results of the empirical analysis, it was found that the conversation material corresponding to informativity did not affect the audiobook during the online quality analysis. It is believed that improvements can be found through content production related to entertainment, webtoons, and general common sense that can increase listeners' interest. In addition, it was found that the advertising effect of celebrities corresponding to interactivity did not affect the results of this study, which should increase the concentration and immersion of listeners by increasing the technology for audiobooks.

Background: As the internet usage becomes easily accessible, the patients are more frequently searching about diseases and medical/non-medical treatments. Considering that complex regional pain syndrome (CRPS) is a debilitating disease, it is important to check the information that patients are accessing. Therefore, this study aimed to investigate the reliability, sufficiency, and accuracy of the YouTube videos about CRPS. Methods: This study is a descriptive research which is derived by searching videos using the keyword 'complex regional pain syndrome' on YouTube. Relevance-based sequencing was used to sort the videos. Sources and video parameters were documented. To evaluate the accuracy, reliability and content quality of the videos, Global Quality Score, Journal of American Medical Association Benchmark Criteria and Modified DISCERN Questionnaire scales were used. Results: A total of 167 videos were included in this study. The majority of the videos originated from USA (80.2%, n = 134). The median number of views was 639 and the viewing rate was 73.3. Most of the videos had partially sufficient data and the interaction index viewing rate parameters for videos with high content quality were greater than videos with low content quality (P = 0.010, P = 0.014). Conclusions: Our results showed that videos about CRPS on YouTube mostly had partially sufficient data and include intermediate-high quality contents. Moreover, high-content quality videos had higher viewing rates, interaction indexes, number of likes, longer durations, as well as better reliability and accuracy scores. Videos with high quality and reliable content are needed to reduce misinformation about CRPS.

Interaction between carcass quality grade and end-point cooking temperature on eating quality of Hanwoo m. longissimus was investigated. Ten (10) of steers were sampled from a commercial population; carcasses with QG 1⁺⁺ (n=5) and QG 1 (n=5) were chosen. Samples were cooked by electric oven at 60 or 82℃ and compared with uncooked control samples. The pH was not affected by cooking temperature but decreased the redness after cooking and steaks cooked at 60℃ were more reddish than steaks cooked at 82℃ in both QG groups. Higher cooking temperature greatly (p<0.05) increased the cooking loss, but there was no significant interaction between cooking temperature and QG on the cooking loss. Moisture is negatively correlated with temperature in both QG while the proportionate relationship between crude fat and end-point temperature found in QG 1⁺⁺. WBSF values were significantly (p<0.05) high for QG 1, while that was significantly (p<0.05) increased when the temperature continues to increase. The increasing quality grade of beef resulted in significant higher (p<0.01) level of TBARS and cooking temperature increased TBARS content. Fatty acid composition was not altered by cooking at both temperatures and also the amount of fat intake was not changed. The current study indicates that eating quality of beef m. longissimus was greatly influenced by end-point temperature being interacted with QG. However, the amount and composition of fat were stable regardless of end-point temperatures. These results will provide a consumer reference to determine cooking conditions and intramuscular fat content.

The intrinsic viscosities were determined for poly(DL-lactic acid) (PDLLA) solutions in 1,2-dialkyl phthalate at temperatures ranging from 30 to $60^{\circ}C$. A series of dialkyl phthalate, in which the alkyl group was changed from methyl to propyl, was used as the solvent to control the solvent quality systematically. The intrinsic viscosity of the PDLLA solution was higher in the better quality solvent, with a higher molecular weight of PDLLA, and at lower temperatures. The unperturbed dimensions of the PDLLA molecule and polymer-solvent interaction parameter of PDLLA in dialkyl phthalate were deduced using extrapolation methods based on the temperature-dependent intrinsic viscosities. Slight shrinkage in the unperturbed chain dimension was observed, which resulted from a change in polymer conformation with temperature. It was also observed that the polymer-solvent interaction became more favorable with the dialkyl phthalate containing a shorter alkyl chain.

본 연구에서는 유아의 기질 및 교사와의 관계가 또래상호작용에 미치는 영향을 밝히고, 기질의 영향력을 교사-유아 간 관계가 조절하는지 살펴보았다. 이를 위해 경기도 소재 사립유치원에 재원중인 만 4, 5세 유아 326명의 어머니와 교사를 대상으로 설문조사를 실시하였으며, 위계적 회귀분석을 사용하여 기질과 교사-유아 관계의 주효과와 상호작용효과를 살펴보았다. 그 결과 유아의 긍정적 또래상호작용에는 교사-유아 간 관계의 주효과와 교사-유아 간 관계 및 정서성 간의 상호작용효과가 발견되어, 교사-유아 간 관계가 유아의 정서성을 조절하는 것으로 나타났다. 한편, 유아의 부정적 또래상호작용에는 유아의 정서성과 활동성 및 교사-유아 간 친밀 및 갈등 관계의 주효과만이 나타났다. 이로써, 또래와의 긍정적인 상호작용을 증진시키고 부정적인 상호작용을 감소시키기 위해서는 교사의 역할이 매우 중요한 반면, 유아의 기질은 부정적인 상호작용에 제한적으로 영향을 미치는 것으로 나타났다.

For the fractional factorial designs, the resolution-IV designs can be used when we want to estimate the main effects and to investigate the structure of the non-negligible two-factor interaction effects, when the three-factor and higher order interaction effects are all negligible. However we need to add the additional treatment combinations in order to identify the influential interactions for the resolution-IV fractional factorial designs. In this paper we investigate the statistical structure for 3-level resolution-IV designs constructed by fold-over scheme and introduce a method for analyzing the influential two-factor interactions.

소프트웨어 공학에서 요구사항 분석은 전체 시스템의 성공률을 좌우한다. 아키텍처에서 발생되는 오류는 전체 시스템에 영향을 주게 되고, 그 결과 소프트웨어 만족도가 낮아진다. 따라서 설계 단계에서 안정적인 아키텍처와 환경을 위하여 소프트웨어 간의 상호작용과 수정할 수 있는 확인이 필요하게 된다. 본 논문에서는 아키텍처 환경 고려 사항의 요소들을 제안하고자 한다.
