The ultimate goal of this study is to investigate the values of internal marketing in Jeju DMO, whether motivates the DMO employees to be more customer-oriented. To verify these hypotheses, 109 valid sample data were selected from among of 124 collected by self-administrated questionnaire survey method. Based on the analysis results, the following strategic implications were suggested: First, internal marketing is seen differently according to gender, age bracket, education, position, experience, job division, contract type. Second, job satisfaction is composed of HR-reward, pride, fellowship and self-realization. Third, customer orientation was research with internal marketing. Fourth, what internal marketing influences job satisfaction and customer orientation shows that it can be used in the HR management aspect. In conclusion, among direct influential factors of internal marketing with job satisfaction and customer orientation, only training was in common with them both.

전기방사기법을 통해 형성된 전기방사 필름은 단위부피당 높은 비표면적을 갖는 구조적인 특징과 더불어, 기계적, 전기적, 광학적 특성을 향상시키기 위한 금속 및 세라믹 나노입자의 첨가가 용이하기 때문에 액체 및 기체 필터, 약물전달, 전지분리막과 같은 다양한 분야에서 응용된다. 본 연구에서는 내화학성 특징을 갖는 polyvinylidene fluoride를 기반으로 하여 흡습 특성이 있는 zeolite가 첨가된 전기방사 필름의 수분 흡수 특성을 분석한다. Zeolite가 첨가된 전기방사 polyvinylidene fluoride 필름은 zeolite의 모세관 현상에 의해 수분 흡착이 발생하고, 연쇄적으로 필름의 다공성 구조 내부로 수분이 침투하는 현상이 나타난다. Zeolite가 포함된 전기방사 polyvinylidene fluoride 필름은 흡습 과정에서 형상 변화 없이 단위 질량 대비 4.2배의 수분 흡수 특성을 보인다. An electrospinning technique is simple method to fabricate porous structure with high surface area per unit volume. Addition of metal/ceramic nanoparticles in electrospinning process is possible to increase film characteristics such as mechanical, electrical and optical properties. Electrospun film shows various applications in diverse fields such as liquid and gas filter, drug delivery system and membrane for metal ion battery separator. In this investigation, we fabricate an electrospun zeolite embedded polyvinylidene fluoride (zeolite/PVDF) film for analysis the water absorption. The materials of polyvinylidene fluoride (PVDF) and zeolite have property with chemically resistance and water absorption, respectively. Electrospun zeolite/PVDF film shows water penetration phenomenon due to the capillary condensation by zeolite structure and is subsequently penetrated into porous structure of electrospun film. As a result, electrospun zeolite/PVDF film shows 4.2 times ratio absorbed mass of water per unit mass of film without deformation.

약용식물인 도꼬마리 추출물을 사용하여 유산균을 이용한 단일 및 복합배양을 통하여 새로운 기능성 물질의 생산을 검토하였다. 도꼬마리 추출물의 유산발효 시 단일배양 결과에서 유산생산을 통해 대체로 잘 증식하는 것이 확인되었으며, H. pylori의 항균 활성은 단일배양보다 복합배양 시항균활성이 아주 우수하였다. 항균성 물질의 분리는 C18 Seppak cartridge에 흡착시켜 30% methanol 용출획분에서 항균성물질이 확인되었으며, TLC로 분석한 결과 Rf 0.46의 위치에서 항균성 물질을 확인하였다. 도꼬마리 유산발효액의 항산 화활성은 총 polyphenol 함량 및 radical 소거능을 검토하였으며, 그 결과 총 polyphenol 함량은 미발효시에 비해 도꼬마리 추출물의 저농도에서 단일배양의 경우 2∼4배 증가하였으며, Lactobacillus brevis KCTC 3498과 Lactobacillus helveticus KCTC 3545를 복합배양한 경우 1 mg/mL 첨가농도에서 polyphenol이 가장 높게 나타났다. Radical 소거능은 도꼬마리 추출물을 0.1 및 0.5 mg/mL로 첨가하여 발효하였을 때 30∼40%의 scavenging이 확인되어 발효를 하지 않았을 때 (25%)보다 발효를 하였을 때 높아지는 것으로 나타났다. 특히 Lactobacillus casei KCTC 3109의 경우 0.1 mg/mL의 농도에서 70%의 scavenging을 나타내었다. 이들 결과로부터 도꼬마리 추출물의 유산발효는 미발효시에 비해 Helicobactor pylori에 대한 항균활성물질의 생산과 기능성물질인 항산화물질의 생산성이 우수하다고 사료되었으며 천연한약재의 발효를 통한 천연물 신약 등 신기능물질의 생산가능성을 확인하였다. This study characterized the anti-Helicobactor pylori activity of Xanthium strumarium L. extract obtained by lactic acid fermentation. The growth of the Lactobacillus strains was typically robust upon lactic acid production in monocultures containing Xanthium strumarium L. extract. Lactic acid fermentation in mixed cultures of Lactobacillus brevis KCTC 3498 and Lactobacillus casei KCTC 3109 produced higher of anti- H. pylori activity than monocultures. Concerning antioxidant activity of fermented extracts, total polyphenol contents were the highest in co-cultures of Lactobacillus brevis KCTC 3498 and Lactobacillus helveticus KCTC 3545. Electron donating ability using diphenyl picryl hydrazyl (DPPH) showed 70% scavenging in Lactobacillus casei KCTC 3109.

A three-dimensional slope valve component is used for controlling micro volume of liquid on a centrifugal force-based microfluidic disk platform, also called a lab-on-a-disk. The modeling factor of the slope valve component is determined to centrifugal force for liquid passing the crest of a slope valve via variation of slope length and angle as well as the radius to start point of slope valve. The centrifugal force is calculated by the equilibrium equation of the capillary and gravitational forces according to the microchannel surface roughness and the liquid volume, respectively. As a result, the slope valve is analyzed by the minimum angular velocity for liquid passing at crest point and the ratio between the length of micro liquid and slope length to obtain the factors for optimal slope angle modeling.

본 연구에서는 중풍, 고혈압, 동맥경화, 염증성 피부질환에 사용되고 있으며, 다양한 질환들에서 연구되어 있는 방풍통성산을 선정하여 4가지 약재를 가미한 후 기존의 기능성 물질과 Lactobacillus 균주에 의해 생성되거나 증가된 기능성 물질을 확인하고자 하였다. 한약을 이용한 복합배양은 공시균주의 수 및 접종시기를 달리하여 여러 조합으로 수행하였다. 전자공여능 및 superoxide dismutase 유사 활성 측정을 통해 한약의 항산화 활성은 각각 31.7%와 36.3%로 나타났으며, 복합배양을 통해 발효된 한약의 항산화 활성은 각각 77% 이상, 42% 이상으로 나타나 한약보다 항산화 활성이 더 높게 나타났다. 항균 활성은 한약의 경우 모든 시험균주에 항균 활성이 나타나지 않았으나, 복합배양 된 한약의 경우에는 B. subtilis PCI 219, P. aeruginosa KCTC 2004, S. aureus subsp. aureus KCTC 1916에 항균 활성을 보였으며, 특히 여드름을 유발시키는 P. acnes KCTC 3314에 항균활성을 보였다. RBL-2H3 세포주에서 알레르기 억제 효과를 확인한 결과 한약은 60% 알레르기 억제 효과를 보였으며, 발효한약은 57% 알레르기 억제 효과를 보였다. 발효한약은 알레르기 억제 효과와 함께 항균 활성과 항산화 활성의 증가로 인하여 알레르기 개선, 피부노화 및 병원성 미생물에 의한 피부질환의 개선에 효과가 있을 것으로 사료된다. Through the process of fermentation with Lactobacillus strains this study has evaluated the functionality of the traditional Korean medicine Bangpungtongsungsan after the addition of four other medicinal ingredients. In order to facilitate the growth of the Lactobacillus strains brown sugar was added to the herbal substances used. For both DPPH radical scavenging activities and SOD-like activities the medicinal mixture, when fermented through heterogeneous co-cultures, scored higher (at 77% and 42%, respectively) than when not fermented (at 31.7% and 36.3%, respectively). The co-cultured Korean medicine inhibited the growth of Bacillus subtilis PCI 219, Pseudomonas aeruginosa KCTC 2004, Staphylococcus aureus subsp. aureus KCTC 1916 and Propionibacterium acnes KCTC 3314. The inhibiting effects on β-hexosaminidase released from RBL-2H3 cells caused by the mixture, with and without fermentation, was seen to be similar (57% and 60%, respectively).

Cytomegalovirus (CMV) is the most common agent of congenital infections and opportunistic infections in an immunocompromised host. CMV in an immunocompetent host has inapparent infections, which are usually asymptomatic or cause mild mononucleosis-like symptoms. However, severe CMV diseases, such as pneumonia, hepatitis, gastrointestinal disease, often occur in a healthy infant. The association of CMV pneumonia with the development of pneumothorax has rarely been reported. We experienced a case of CMV pneumonia presenting as pneumothorax in a 4-month-old healthy infant, who was successfully treated with supportive care. CMV was confirmed by using CMV polymerase chain reaction of tracheal aspirates. This case suggested that CMV should be considered as a cause of viral pneumonia during the infant period.
