본 연구는 그동안 탁월한 치유의 기능이 내재되어 있다고 알려진 시조의 감정 코드들을 분석하여 인문학적 치유의 콘텐츠를 활성화시키고자 하는 데에 목적이 있다. 치유작용의 일환으로써의 시조는 여러 작품들을 감상하는 과정에서 형성되는 감정의 융합을 통해 감정의 총체라 할 수 있는 치유의 감정 코드들을 형성한다. 이러한 과정은 인체생리학적으로 인체 내에서의 문학치료의 진행을 가능하게 한다. 머신러닝이 인지기능에 의해 스스로 학습하는 것처럼 상시적으로 부호화와 재부호화에 대한 코딩 과정이 인체 시스템의 수많은 뉴런들의 집합체들에서 작동된다. 그 과정에서 감정 코드들의 집합적인 부호화에 의해 인체 내에서 아미노산이 합성되는 것으로 예측된다. 이러한 아미노산들이 인체의 신호 체계를 조절하는 것이다. 향후 이러한 인문학과 인체생리학의 접점에서의 치료의 연구가 진행된다면 보다 질 높은 인문학적 치유의 프로그램이 활성화될 것으로 기대된다.

With the increasing incidence of AIDS, it is probably inevitable that nurses working in hospital and community settings will come in contact with patients with AIDS. Nurses, more than any other health care profession, are on the front line of AIDS patient care. The purposes of this descriptive study were to gather information about registered nurses' knowledge and attitude regarding AIDS. and to provide a basis for the development of continuining education programs for the nurse. Data was gathered in 1988 using self-administered questionnaires given to a convinience sample of two hundred seventy registered nurses from two university hospitals, school nurses and postgraduate students of nursing. Data was analyzed with SAS. The results were as follows. Above 90% of the nurse knew well about definition of AIDS and routes of transmission but nurses relatively lacked knowledge about transmission of HIV in breast milk(69.3%). Less than half knew that drug abuser(44.1%) and sexual partner with IV drug abuser(39.6%) are at high risk for contracting AIDS. Above 70% of the nurse showed reluctance to provide care for surgery. delivery of child birth and hemodialysis of patients with AIDS. The results showed that, given a choice. 41.7% of the nurse would refuse to care for AIDS patients and 48.3% claimed that they should have a right refuse to care for AIDS patients. Reluctance of nursing patient with AIDS appeared to be principally associated with general fear of becoming infected with HIV. 41.8% exhibited a sympathetic attitude toward individual AIDS patient. The study findings suggest that it is necessary to examine the correlations between knowledge and attitude and to develop continuing education programs that alleviate the fear of contagion of the nurse.

ZnO nanowire is known as synthesizable and good mechanical properties. And, stimuli-responsive polymer is widely used in the application of tunable sensing device. So, we combined these characteristics to make precise tunable sensing devise. In this work, we investigate the dependence of ZnO nanowire alignment and morphology on si substrate using nanosphere template with various conditions via hydrothermal process. Also, pH-temperature dependant tuning ability of nanostructure was studied. The brief experimental scheme is as follow. First, Zno seed layer was coated on a si wafer ($20{\times}20mm$) by spin coater. And then $1.15{\mu}m$ sized close-packed PS nanospheres were formed on a cleaned si substrate by using gas-liquid-solid interfacial self-assembly method. After that, zinc oxide nanowires were synthesized using hydrothermal method. Before the wire growth, to specify the growth site, heat treatment was performed. Finally, NIPAM(N-Isopropylacrylamide) was coated onto as-fabricated nanostructure and irradiated by UV light to form the PNIPAM network. The morphology, structures and optical properties are investigated by FE-SEM(Field Emission Scanning electron Microscopy), XRD(X-ray diffraction), OM(Optical microscopy), and WCA(water contact angle).

To prepare bio-inspired antifouling coating materials having similar structure with lotus, self-crosslinkable waterborne polyurethanes emulsions containing paraffin wax (CWPU/P0, 0.25, 0.5, 1.0, 1.5, 2.0, the number indicated the wt% of wax) were prepared by an emulsifier-free/solvent free prepolymer mixing process. The as-polymerized CWPU/P emulsions containing 0 - 1.00wt% of paraffin wax were found to be stable after 4 months, however, CWPU/P emulsions containing 1.50 and 2.00wt% of paraffin wax were unstable within 1 month storage. Considering the stability of emulsions, the optimum paraffin wax content was found to be about 1wt% to obtain stable antifouling coating emulsion material. The surface topology of CWPU/P film samples was characterized by atomic force microscopy (AFM). This study examined the effect of paraffin wax content on the surface roughness, water contact angle/surface energy, water swelling, light transmittance and tensile properties of CWPU/P film samples.

The control of wettability of thin films is of great importance and its success surely brings us huge applications such as self-cleaning, antifogging and bio-passive treatments. Usually, the control is accomplished by modifying either surface energy or surface topography of films. In general, hydrophobic surface can be produced by coating low surface energy materials such as fluoropolymer or by increasing surface roughness. In contrast, to enhance the hydrophillicity of solid surfaces, high surface energy and smoothness are required. Silica (SiO2) is environmentally safe, harmless to human body and excellently inert to most chemicals. Also its chemical composition is made up of the most abundant elements on the earth's crest, which means that SiO2 is inherently economical in synthesis. Moreover, modification in chemistry of SiO2 into various inorganic-organic hybrid materials and synthesis of films are easily undertaken with the sol-gel process. The contact angle of water on a flat silica surface on which the Young's equation operates shows ~50o. This is a slightly hydrophilic surface. Many attempts have been made to enhance hydrophilicity of silica surfaces. In recent years, superhydrophilic and antireflective coatings of silica were fabricated from silica nanoparticles and polyelectrolytes via a layer-by-layer assembly and postcalcination treatment. This coating layer has a high transmittance value of 97.1% and a short water spread time to flat of <0.5 s, indicating that both antireflective and superhydrophilic functions were realized on the silica surfaces. In this study, we assessed hydrophillicity and hydrophobicity of silica coating layers that were synthesized using the sol-gel process. Systematic changes of processing parameters greatly influence their surface properties.
