        This study examines the effects of the public’s perception of emergency medical service (EMS) on the public health system’s brand equity and the moderating effect of governance on this relationship using Keller’s customer-based brand equity model. It uses four EMS functions: rescue/first-aid and transfer activities; disaster prevention, preparation, and response activities; educational activities in urgent situations; and medical treatment in emergency rooms to examine the effects of them on brand meaning of the public health system. Our findings are important for understanding the public as customers of the public health system and devising and/ or adapting healthcare policies and marketing strategies to develop brand equity and increase customers’ loyalty to the public health system.

        본 연구에서는 싸이크론 헥산에서 PVC와 트리에틸디아민 (TEDA), 1,4-디메틸피페라진 (DMP) 및 1,4-비스(이미다졸-1-일메틸)벤젠을 각각 치환반응시켜서3가지 형태의 PVC 멤브레인, AEM-1, AEM-2, and AEM-3를 제조하였다. AEM-1, AEM-2, and AEM-3멤브레인의 성공적인 제조 여부를 이온전도도(S/cm), 물함수율 (%), 접촉각, 이온교환능력 (meq/g), 열분석, SEM 및 XPS 분석 통하여 확인하였다. 또한, 제조된 가교 음이온 PVC멤브레인을 사용하여 유기전해질에서 전기화학 캐퍼 시터 실험을 수행한 결과, 제조된 AEM-1, AEM-2 AEM-3 멤브레인의 경우 유기전해질에서 충/방전 실험결과 매우 안정적임을 확인 할 수 있었다. 이러한 결과로 치환반응 후에 용매 캐시팅법으로 제조 된 PVC기반 멤브레인 (AEM-1, AEM-2, 및 AEM-3)의 경우 유기전기화학캐퍼시터 (슈퍼캐퍼시터)용 분리막으로 사용될 수 있다.

        Free-living nematodes feed on bacteria, algae, fungi, dead organisms, and living tissues. They release nutrients for plant use and improve soil structure and water holding capacity. They are usually the most abundant type of nematodes in soil and marine environments. This study has been conducted to survey the distribution and identification of soil nematodes from rhizosphere soil of plant for investigation of indigenous species according to Convention on Biological Diversity. Three species of free-living nematodes belonging to the order of Dorylaimida were found from paddy soil and soybean fields, Miryang, Gyeongsangnam-do and one species was found from soil, Dokdo island, Gyeongsangbuk-do, Korea. Aporcelaimellus obtusicaudatus, Eudorylaimus arcus and Mesodorylaimus spengelii are newly collected from Korea. A. obtusicaudatus can be recognized by its large body, short odontostyle being much thicker than cuticle at the same level, well developed gonads, shape and length of the tail. E. arcus is distinctive because of the wide lateral field, tail form and supplement arrangement. M. spengelii is smaller species with short odontostylet, simple guiding ring. Female tail more or less uniformly attenuated, tip is not swollen, nor curved dorsally.

        This study was carried out determination of characteristics of leaf and fruit of 13 astringent persimmon (Diospyros kaki) cultivars cultivated in Gyeongsangnam-do, Korea. In leaf size, Deabonggam was smaller than that of other astringent persimmon cultivars, however, Dansungsi and Bansi were largest compared to other persimmon cultivars. Fruit width size of Sancheong Deabonggam and Bansi were the biggest. And fruit width size was the biggest in Sancheong Deabonggam. When same cultivars as Dansungsi and Godongsi were cultivated at other regions, it was not somewhat different in fruit weight. The size of fruits of the cultivar varied depending on the maturation of the fruits. In immature fruit, Curigam and Susi cultivars were the biggest and these cultivars were also were the biggest in mature-green fruit. In full ripe fruit, Hamyang Daebonggam and Hadong Daebonggam and Daeheakmu were bigger than that of other cultivars. When the astringent persimmon varieties collected in July were divided into three clusters, group A had a higher leaf area and the lightest fruit weight than the other clusters. In cluster C, the leaf area was small, but the fruit weight was classified as heavier than the other clusters. This study is expected to be widely used for breeding, conservation and processing of sweet persimmons.

        본 연구는 기존 선박에 자외선 (UV) 평형수처리장치(BWMS)를 설치 한 경우, 수치 계산을 통해 평형수 처리시간의 증가를 정량적으로 조사하였다. 계산 결과 배수량 55,000톤 가스 운반선의 평형수 처리시간은 UV BWMS 미설치 및 유량 제어 기능 없이 2.152 시간이었다. 평형수 처리시간은 UV BWMS 설치 후 14.2 % 증가했으며, 유량 제어 기능까지 고려 시 20.4 % 증가했습니다. 실제 조건들을 고려하면 UV BWMS 설치 후 평형수 처리시간은 기존 평형수처리시간 대비 최소 30 % 정도 증가할 것으로 예상됩니다. 따라서 업계 관계자는 평형수 처리시간 증가로 인한 선박 운영 손실을 최소화하기 위하여 UV BWMS 선정시 본선의 실제 평형수펌프 용량과 UV BWMS의 유동 에너지 손실을 충분히 고려하는 것이 좋습니다. 또한 BWMS 설치 후 평형수 처리시간 증가를 최소화하기 위해서는 더 큰 용량의 BWMS, 더 큰 파이프 및 내부 코팅이 있는 파이프 등의 사용을 고려할 수 있습니다.

        Background: Previous robot-mediated gait training has been proven several limitations such as pointless repeated motion training, decreased presence, etc. In this research, adult stroke patients were participated in robot-mediated gait training accompanied with or without virtual reality program. Objectives: Exploring whether the results indicated virtual reality system has contribution to muscle strength and balance ability. Design: A case series research, cross-over trial. Methods: Eleven participants (male 4, female 7) with adults diagnosed as stroke from medical doctor ware engaged. The participants received 2 treatment sessions of identical duration, robot-assisted gait training with virtual reality and robot-assisted gait training with screen-off randomly crossed over include 1-day for each person of wash-out period. The parameter was muscle activity, the researchers assessed sEMG (surface electromyography). Results: The result showed less muscle activities during training in robotassisted gait training with virtual reality circumstances, and these indicated muscles were gluteus medius muscle, vastus medialis muscle, vastus intermedius and vastus lateralis muscle, semimembranosus muscle, gastrocnemius- lateral head, and soleus muscle (P<.05). Conclusion: In this study, we analyzed the outcome of muscle activity for clinical inference of robot-assisted gait training with virtual reality (VR). Less muscle activity was measured in the treatment accompanied by VR, therefore, a more systematic, in-depth and well-founded level of follow-up research is needed.
