The purpose of this study is to provide some basic data for the direction of nursing education and practice to prevent nursing malpractice as investgating perception of the nurse on the nursing malpractice and its case. Data were collected from 450 nurse working in four general hospitals which were located in Chonbuk province from November 9 to 21, 1998 through questionnare. The structured instruments developed by the reseacher were used for collecting data. The Results were as follows: 1) As for the cognition of the nursing malpractice case, the transfusion accident was 37.3%, the side-effects of KCL injection(19.3%), hymen rupture by uterus cancer test, the side-effects of aminophyllin injections on dyspnea patient and the others were 10% below. 2) With regard to the channel of the perception of the nursing malpractice case, mass-communication was taken first and followed through by neighbors, In-service education, school education, continuing education 3) As for the direct${\cdot}$indirect experience of the nursing malpractice case, transfusion accident was 51.3%, the fall of NPO patient after an operation 40.1%, the side-effect of KCL injection 32.5%, suicide of the psychiatric patient 32.5%, and the others were 30% below. 4) The possibility of nursing malpractice case was an average 2.57(${\pm}$0.91) and the highest was the fall of the NPO patient after an operation. 5) The perception on the responsibility of the nursing malpractice in its case was indicated as a joint-fault in ten nursing malpractice instances. As compared to the real decision, nurse's perception of the responsibility in the fall of the NPO patient after an operation, the side-effect of KCL injection, the tracheal edema of the patient who had a thyroid operation, the suicide of psychiatric patient, the hymen rupture by uterus cancer test accorded real decisions. But the other cases were different from the real decisions. These cases were perceived as ones of joint fault even in cases determined as Dr's single fault cases or those in which both doctor and nurse were declared free of fault. 6) Knowledge levels of the nursing malpractice, school education and In-service education were perceived as low but anxiety levels of the malpractice were high. 7) With regard to the countmeasure of the hospital after nursing malpractice, the rate answered as "the practice settled the accident temporarily and forced the person in charge to be punished" was highest. In conclusion, the level of the cognition of the clinical nurse on nursing malpractice cases was low. As nurses' perception on the responsibility of the nursing malpractice case was compared to the real decision, there was a difference in five cases out of the ten cases.

인체의 $40{\sim}50%$인 연부조직에 X선을 조사하면 연부조직의 두께에 따라 투과선량이 감소하며 영상에도 질적 저하를 가져온다. 본 연구는 복부 촬영시 위장내 내용물에 따라 X선 감약 및 화질에 차이가 나타날 수 있다는 가정 하에 실제 위의 조직과 비슷한 조직등가물질 phantom을 제작하여 실제 위장내 내용물에 따른 X선의 감약 변화와 DR (Digital Ridiography)의 ROI수치를 비교해보았다. 단백질 두께가 증가할수록 X-선 감약에 의한 투과선량이 감소되었으며(p < 0.001), Film과 DR 영상에서의 ROI Mean값의 변화도 감소하였다(p <0.001). Film과 DR 영상에서의 ROI Mean값에 대한 비교는 Film이 DR 영상에 비해 단백질 두께에 따른 농도의 변화 값이 크게 나타났다(p < 0.001). 이와 같은 결과를 종합해 볼 때 DR system 촬영 보다는 필름을 사용하는 단순촬영에서 금식(NPO ; nothing by mouth)의 필요성이 더 중요함을 알 수 있다.

This paper aims to identify the characteristics and the current situation of the architectural characteristics, children's characters using facilities, and status of management and utilization by surveying 'Day Service for Children' in Tokyo-do. First, About the status of management and utilization, 'Day Service for Children' is operated by a local government, NPO corporate group and social welfare corporate. There are not big differences of the care program or running hours depending on operating principals but there are differences depending on staff organization, number of children and space constitution. Also, infants ratio at 'Day Service for Children' is high for the purpose of detecting disability early and supporting their development early. They have diverse disabilities but developmental disabilities' ratios high and most children are using both this facility and normal nursery centers together. Samples for proper child care based on status of space constitutions were installing lock, raising door knobs and using softer floor materials which are for children's safety. For the problem of space utilization, most comments were about lack of space which is not enough for teaching and training materials. Therefore, as an example, observation rooms for parents and teachers were sometimes used as storages and it changes teachers' moving direction, staying area and behavior zone. The programs of 'Day Service for Children' are divided to group teaching and private one. It will be the best if they have separate spaces such as group class room, private class room and play room. When they were operated by NPO corporate group or Social welfare corporate, there are many cases that their space was not properly zoned for each activity.

Purpose: Undernutrition during hospitalization increases the risk of nosocomial infection and lengthens the disease courses. The aim of this study was to evaluate the risk factors of weight loss during hospitalization in children. Methods: All the patients who were admitted in general wards between April and May 2014 were enrolled. Patients aged >18 years and discharged within 2 days were excluded. Weight loss during hospitalization was defined as a decrease in body weight of >2% in 8 hospital days or on the day of discharge. Patients who lost body weight during hospitalization were compared with patients who maintained their body weights. Significant parameters were evaluated by using the multivariate logistic regression analysis. Results: We enrolled 602 patients, of whom 149 (24.8%) lost >2% of their body weight. Complaint of pain (p=0.004), admission to the surgical department (p=0.001), undergoing surgery (p=0.044), undergoing abdominal surgery (p=0.034), and nil per os (NPO) durations (p=0.003) were related to weight loss during hospitalization. The patients who had high weight-for-age tended to lose more body weight (p=0.001). Admission to the surgical department (odds ratio [OR], 1.668; 95% confidence interval [CI], 1.054-2.637; p=0.029) and long NPO durations (OR, 1.496; 95% CI, 1.102-2.031; p=0.010) were independent risk factors of weight loss during hospitalization. The patients with high weight-for-age tended to lose more weight during hospitalization (OR, 1.188; 95% CI, 1.029-1.371; p=0.019). Conclusion: Greater care in terms of nutrition should be taken for patients who are admitted in the surgical department and have prolonged duration of nothing by mouth.

$MgTiO_3$ thin films were prepared by r.f. magnetron sputtering in order to prepare miniaturized NPO type MLCCs. $MgTiO_3$ films showed a polycrystalline structure of ilmenite characterized by the appearance of (110) and (202) peaks. The intensity of the peaks decreased with an increase in the chamber pressure due to the decrease of crystallinity which resulted from the decrease of kinetic energy of the sputtered atoms. The films annealed at $600^{\circ}C$ for 60min. showed a fine grained microstructure without micro-cracks. The grain size and roughness of the $MgTiO_3$ films decreased with the increase of chamber pressure. The average surface roughness was 1.425~0.313 nm for $MgTiO_3$ films prepared at 10~70 mTorr. $MgTiO_3$ films showed a dielectric constant of 17~19.7 and a dissipation factor of 2.1~4.9% at 1MHz. The dielectric constant of the films is similar to that of bulk ceramics. The dielectric constant and the dissipation factor decreased with the increase of the chamber pressure due to the decrease of grain size and crystallinity. The leakage current density was $10^{-5}\sim10^{-7}A/cm^2$ at 200kV/cm and this value decreased with the increase of the chamber pressure. The small grain size and smooth surface microstructure of the films deposited at high chamber pressure resulted in a low leakage current density. $MgTiO_3$ films showed a near zero temperature coefficient and satisfied the specifications for NPO type materials. The dielectric properties of the $MgTiO_3$ thin films prepared by sputtering suggest the feasibility of their application for MLCCs.

Background: Postoperative chylothorax may be caused by iatrogenic injury of the collateral lymphatic ducts after thoracic surgery. Although traditional treatment could be considered in most cases, resolution may be slow. Radiological interventions have recently been developed to manage postoperative chylothorax. This study aimed to compare radiological interventions and conservative management in patients with postoperative chylothorax. Methods: We retrospectively reviewed periprocedural drainage time, length of hospital stay, and nil per os (NPO) duration in 7 patients who received radiological interventions (intervention group [IG]) and in 9 patients who received conservative management (non-intervention group [NG]). Results: The baseline characteristics of the patients in the IG and NG were comparable; however, the median drainage time and median length of hospital stay after detection of chylothorax were significantly shorter in the IG than in the NG (6 vs. 10 days, p=0.036 and 10 vs. 20 days, p=0.025, respectively). NPO duration after chylothorax detection and total drainage duration were somewhat shorter in the IG than in the NG (5 vs. 7 days and 8 vs. 14 days, respectively). Conclusion: This study showed that radiological interventions reduced the duration of drainage and the length of hospital stay, allowing an earlier return to normal life. To overcome several limitations of this study, a prospective, randomized controlled trial with a larger number of patients is recommended.

Development of drugs from natural products has been undergoing a gradual evoluation. Many plant derived compounds have excellent therapeutic potential against various human ailments. They are important sources especially for anticancer agents. A number of promising new agents are in clinical development based on their selective molecular targets in the field of oncology. D-pinitol is a naturally occurring compound derived from soy which has significant pharmacological activitites. Therefore we selected D-pinitol in order to evaluate apoptotic potential in the MCF-7 cell line. Human breast cancer cells were treated with different concentrations of D-pinitol and cytotoxicity was measured by MTT and LDH assays. The mechanism of apoptosis was studied with reference to expression of p53, Bcl-2, Bax and NF-kB proteins. The results revealed that D-pinitol significantly inhibited the proliferation of MCF-7 cells in a concentration-dependent manner, while upregulating the expression of p53, Bax and down regulating Bcl-2 and NF-kB. Thus the results obtained in this study clearly vindicated that D-pinitol induces apotosis in MCF-7 cells through regulation of proteins of pro- and anti-apoptotic cascades.

Purpose: The purpose of this study was to identify the occurrences and the factors contributing to constipation in the post surgical period following major orthopedic surgery. Methods: The sample included 133 patients who had surgery of the hip, knee, or spine. Patients were excluded from the study if there was a history of bowel surgery or constipation from chart review. Data were collected using questionnaires such as Korean version of Modified Barthel index (K-MBI), Hospital Anxiety and Depression Scale, and Constipation Assessment Scale (CAS) before surgery and on the third postoperative day. Results: Reports of constipation occurred in 77 instances (57.9%). The first reported defecation was within $4.0{\pm}2.2days$ following surgery. Mean days of first defecation of constipation group vs. non-constipation group was $5.5{\pm}1.7days$ vs. $2.1{\pm}1.0days$. There were statistically significant differences between patients who reported than those who did not in terms of age, length of NPO period, postoperative ADL, and the reported incidents of preoperative and postoperative depressive symptoms. Postoperative ADL, age, and NPO period were significant influencing factors of constipation and explained 52.4% of the variance. Conclusion: Constipation is a very common symptom for patients undergoing orthopedic surgery. These results indicate a need for improving patient's ADL after surgery to prevent constipation.
