As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Spontaneous esophageal perforation (Boerhaave Syndrome) is an unusual condition that frequently leads to fatal complications. It typically occurs with rigorous emesis after an unduly large meal or heavy drinking. Its diagnosis is often delayed in almost all cases due to nonspecific symptoms and signs, resulting in increased morbidity and mortality. Therefore early diagnosis and appropriate treatment are very important. Recently we experienced a case of esophagogastric junctional perforation accompanied by bilateral empyema and mediastinitis after heavy alcohol drinking in a 56-year-old male patient. He was presented with hematemesis and abdominal pain. We diagnosed him using esophagography and chest CT. Thus, we report a case with a brief review of related literatures.

<P>Nitrogen (N)-doped graphitic layers were deposited as shells on pregrown silicon nanowires by chemical vapor deposition. Graphite-like and pyridine-like structures were selectively chosen for 3 and 10% N doping, respectively. Increasing the thickness of the undoped graphitic layers from 20 to 50 nm led to an increase in the charge capacity of the lithium ion battery from 800 to 1040 mA h/g after 45 cycles. Graphite-like 3% N-doping in the 50 nm-thick shell increases the charge capacity by 21% (i.e., to 1260 mA h/g), while pyridine-like 10% N-doping in the 20 nm-thick shell increases it by 36% (i.e., to 1090 mA h/g). This suggests that both pyridine- and graphite-like structures can be effective for lithium intercalation. First principles calculations of the graphene sheets show that the large storage capacity of both N-doping structures comes from the formation of dangling bonds around the pyridine-like local motives upon lithium intercalation.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2011/jpccck.2011.115.issue-19/jp201485j/production/images/medium/jp-2011-01485j_0001.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp201485j'>ACS Electronic Supporting Info</A></P>

대표적인 지향성 안테나인 야기 안테나를 무인 경계 레이더 센서에 적용 가능하도록 설계, 제작하였다. 본 논문에서 제안된 안테나가 무인 경계 레이더 센서에 적용되기 위해서는 7.2-8.2GHz의 동작주파수, 7dBi 이상의 최대 방사 이득과 60° 이상의 3dB 빔폭을 만족하여야한다. 7dBi 이상의 최대 방사 이득과 60° 이상의 빔폭을 얻기 위해 3 개의 디렉터를 가진 야기 안테나를 유전체 기판 위에 설계하였다. 또한 드라이브 단의 밸런스드 급전을 위하여 Microstrip-to-CPS 발룬을 설계하여 제안된 안테나에 적용하였다. 제안된 안테나의 가상 실험 결과와 측정 결과를 비교하여 제안된 안테나의 성능을 검증하였다. A Yagi antenna, which is a typical directional antenna, has been designed and fabricated as a surveillance sensor. The proposed Yagi antenna satisfies the requirements as a surveillance sensor; impedance bandwidth of 7.2-8.2GHz, maximum gain of 7dBi, and 3dB beamwidth of 60〫 in the azimuthal plane. The proposed Yagi antenna is designed with 3 directors and one driven element on a dielectric substrate. Also, a microstrip-to-CPS balun is designed and applied to the proposed antenna for balanced feeding of the dirven element. The performance of the proposed antenna has been verified by comparing the simulation and measurement results.

We developed a novel shallow junction formation technique for SOI p-MOSFET application. A poly boron lm (PBF) was used as the diusion source for a solid phase diusion (SPD) process. Rapid thermal annealing (RTA) was utilized to diuse the boron from the PBF source. With the advantages of the SPD technique, an extremely shallow p+-n junction less than 10 nm in depth was formed and the p+-n-n+ diodes showed excellent junction properties. Based on optimized device fabrication processes, SOI p-MOSFETs with a gate length of 35 nm were successfully fabricated and revealed good electrical characteristics and superior device scalability.

This study was conducted to determine effects of soil pH and form of nitrogen fertilizers on tomato growth and chemical properties of greenhouse soil using ferigation system. Tomato (Lycopersicon esculentum Mill. cv. Superdoterang) were grown for three months in 18 L pots filled with two soil (pH 6.8 and pH 8.7). 4 different nitrogen fertilizers (urea, ammonium nitrate, ammonium sulfate, and potassium nitrate) were fertigated with different concentrations of 0, 10, 50, and 100 mg N/L during tomato cultivation. Soil pH 8.7 decreased yield and chlorophyll fluorescence compared with soil pH 6.8. Yield at soil pH 8.7 increased by ammonium nitrate and ammonium sulfate fertigation. Soil pH 6.8 induced increment of yield by nitrogen concentration than form of nitrogen fertilizers. Soil pH after cultivation of tomato decreased by application of ammonium nitrate and ammonium sulfate. Soil EC by 100 mg N/L application of ammonium sulfate was twice as much as other fertilizers. Form of nitrogen fertilizer had less effect on concentration of soil NH4+-N and NO(3-)-N in soil but the concentrations slightly reduced at pH 8.7. These results indicate that application of urea and ammonium nitrate for a nitrogen source of fertigation has little affects on soil chemical properties before and after tomato cultivation.
