목적: 본 연구는 성인(18~54세)을 대상으로 연세 라이프스타일 프로파일-실행(Yonsei Lifestyle Profile- Active, Balanced, Connected, Diverse: YLP-ABCD)의 신뢰도와 타당성을 검증하여 연령층에 관계없이 적용 가능한 건강 라이프스타일 평가도구로서의 확장 가능성을 확인하고자 하였다. 연구방법: 본 연구는 성인(18~54세) 300명과 중고령자(55세 이상) 299명, 총 599명을 대상으로 온라인 설문조사를 통해 YLP-ABCD의 신뢰도와 타당성을 검증하였다. 기술통계와 빈도분석을 통해 인구학적 특성을 파악하였고, 신뢰도 검증을 위해 Cronbach’s α와 Spearman-Brown 계수를 사용하여 내적 일관성을 분석하였다. 또한, Fisher’s z-test를 통해 성인과 중고령자 그룹 간의 상관계수 차이를 비교하여 YLP-ABCD의 동시타당도를 평가하였다. 결과: YLP-ABCD 평가도구의 신뢰도와 타당도를 분석한 결과, 신체활동, 식습관, 사회관계, 작업참여의 각 영역에서 높은 신뢰도(Cronbach’s α = 0.929, Speraman-Brown = 0.627)를 확인하였다. 또한, 성인과 중고령자 간 Pearson 상관계수의 차이가 유의미하지 않아(p > 0.05) 두 집단에 걸쳐 평가도구의 타당성이 일관되게 유지됨을 입증하였다. 결론: Y본 연구는 LP-ABCD가 성인과 중고령자 모두에게 일관된 신뢰도와 타당성을 가지는 평가도구임을 확인하였다. 이를 통해 YLP-ABCD는 연령에 관계없이 라이프스타일을 평가하는 유효한 도구로 활용 가능함을 입증하였으며, 이를 기반으로 다양한 연령층을 위한 맞춤형 건강 관리 프로그램 개발에 기여할 수 있을 것으로 기대된다.

The ultimate goal of seawater reverse osmosis brine management is to achieve minimal liquid discharge while recovering valuable resources. The suitability of an integrated system of membrane distillation (MD) with sorption for the recovery of rubidium (Rb⁺) and simultaneous SWRO brine volume reduction has been evaluated for the first time. Polymer encapsulated potassium copper hexacyanoferrate (KCuFC(PAN)) sorbent exhibited a good selectivity for Rb⁺ sorption. The integrated MD-KCuFC (PAN) system with periodic membrane cleaning, enabled 65% water recovery. A stable MD permeate flux was achieved with good quality permeate. KCuFC (PAN) showed a high regeneration and reuse capacity. Ammonium chloride air stripping followed by resorcinol formaldehyde resin filtration enabled to recover Rb⁺ from the desorbed solution.

In order to export Korean spray roses to the China, it is needed to analyse chinese preferences, rose attributes, and purchase intentions. The purpose of this study is to present the implications on the production and distribution of roses for export by analyzing the quality preference attributes and purchase intention of Korean rose for Chinese flower experts. A survey on the preference and purchase intention of Korean flower roses by Chinese flower experts was conducted through face - to - face interviews with flower show participants in China. Approximately 100 Chinese flower experts who participated in the Flower Show in 2016 received the questionnaire, and 86 survey results could be used for analysis. Survey data were analyzed using ordered probit and bivariate probit models. As a result of an analysis, it was found that Chinese flower experts were more likely to buy Korean roses than Chinese roses even if they consider flower color, leaf shape and size and color diversity. The probability of purchasing more than twice the price was higher than that of the color diversity considering the flower shape, leaf shape and size, but the bivariate order probit model was larger than that of flowers, leaves and size, and the order of probability size was changed. In order to increase the export of Korean spray roses to the Chinese market, We need to increase Chinese experts’ preferences and satisfaction. For this purpose, it is very important to develop export varieties of roses with large flower buds and shape / coloring, and to apply the useful post-harvest technology that can extend freshness and distribution period of export roses.
