The objective of this study was to document how clinical dietitians working at tertiary hospitals spend their time based on several categories of activities using a time measurement study. The questionnaires were distributed to 14 tertiary hospitals, and dietitians answered by classifying their work activities into several categories such as general care, indirect care, direct care, outpatient care, and food service management. A total of 129 clinical dietitians replied and their answers were analyzed according to the categories of activities. The times spent on the categories are as follows: general care (76.7 mins/day, 14%), indirect care (228.4 mins/day, 35%), direct care (120.1 mins/day, 22%), outpatient care (61.5 mins/day, 11%), and food service management (99.0 mins/day, 18%). The total working hours for dietitians was 590.0 mins, which exceeds the standard working hours of 540.0 mins (9 hrs) a day. From this study, we found that clinical dietitians spent very limited time on direct care. Times spent on activities were different according to type of employment and food service. Internship dietitians spent their more time on general care (P<0.001) while irregular dietitians spent more time on outpatient care (P<0.05). In contracted managed food service hospitals, clinical dietitians spent significantly less time on food service management (P<0.001). Regardless of doctors' order and consultation fees, clinical dietitians performed more than 95 percent of free consultation to patients. Entry-level knowledge and skills of dietitians working at hospitals are very important for quality service, but it is equally important to create an administrative and social environment that encourages clinical dietitian to spend more time on direct patient care.

The present study was conducted to provide the basis for improvement of clinical nutrition services through development of job standards of clinical dietitian for the clinical nutrition therapy to cancer patients in hospitals. Developing A Curriculum (DACUM) method was used for job analysis and development of job standards for clinical dietitians for cancer care. Based on DACUM analysis, information about duties, tasks, and task elements of clinical dietitians for cancer care was collected. Developed job standards were applied to clinical nutrition care for cancer patients in hospitals for evaluation. Based on DACUM analysis, consultations from professionals, and field application tests, the final job standards were composed of four duties, 18 tasks, and 56 task elements. The duties consisted of nutritional assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring evaluation. For cancer nutrition care, 109 work activities were developed. They were composed of 75 basic and 34 recommended work activities. The application of developed job standards for clinical dietitians for cancer care at 10 hospitals showed a performance rate of 72.3%. In conclusion, job standards for clinical dietitians for cancer care developed in this study might be effectively used as guidelines for providing clinical nutrition services for cancer patients in hospitals.

The purpose of this study was to evaluate nurses' perception of clinical nutrition services. A cross-sectional survey design was performed. The research was accomplished by using questionnaires developed for this study and administered from September 12 to December 31, 2013 to 343 nurses at 43 tertiary hospitals and 20 general hospitals. The percentage of nurses who recognized clinical nutrition certificate as issued from nation was 27.8%. The mean scores of perceived usefulness on clinical nutrition services was 4.23/5.00, whereas that of perceived implementation was 3.76/5.00. The mean scores of necessity of disease-specialized clinical dietitian at capital hospitals were significantly higher for obesity (P<0.01), cancer (P<0.05), and infant & childhood disease (P<0.01) than at local hospitals. The rates of nurses' experience in group education on cancer at capital hospitals (21.7%) was significantly higher than that at local hospitals (10.3%) (P<0.05). The mean scores of perceived importance of clinical nutrition services were 4.46/5.00 for 'group nutrition education', 4.46/5.00 for 'individual consultation', and 4.40/5.00 for 'nutrition management for enteral nutrition (EN) patients'. The most common reason why clinical nutrition services are important was 'improving malnutritional status'. To activate clinical nutrition services especially at local hospitals, clinical dietitians should give systematic assistance to patients and also institutional supports are needed.

The objective of this study was to examine job satisfaction status and its related factors among dietitians working in hospitals. A survey questionnaire was sent to dietitians working in tertiary, general, and convalescent hospitals in Korea. The study sample hospitals included all tertiary hospitals (n=43), and the sample of general hospitals (n=114) and convalescent hospitals (n=240) was randomly selected using a stratified sampling method. A total of 665 dietitians completed the survey questionnaire. The questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas, and the questions on task improvement need. The job satisfaction scores in all four areas ranged from 2.53/5.00 to 3.89/5.00, implying generally low job satisfaction level in hospital dietitians. The job satisfaction levels in the convalescent hospital group were significantly lower compared to those in the tertiary and general hospital groups. Whereas job satisfaction levels of tertiary and convalescent hospital groups did not differ by number of beds, those of the general hospital group increased significantly with the number of beds for all four areas. Multivariate regression analysis results showed that hospital type was a significant predictor of job satisfaction level for all four areas. Job satisfaction of relationship area was also significantly affected by the number of beds, whereas that of working conditions was influenced by annual income and working experience. The study findings provide useful information in planning clinical dietitians' optimal supply outlook for the improvement of clinical nutrition services.

Recently, the interest and demand on free formed structure providing aesthetic value as well as functionality has been increasing. Formwork has numerous advantages such as high strength, convenience, accuracy and good quality of surface roughness. Nevertheless, it increases construction cost and period to build complex shapes. For these purpose, deposition construction systems such as Contour Crafting and Concrete Printing have been developed with active collaboration between university and industry by applying the rapid prototyping technology to the construction industry in USA and England. Since there has been no related research in Korea, the possibility of spin-off technology and its fusion cannot be expected. In this paper, design elements including mechanical system and control system related to automatic deposition construction system prototype for constructing a free curved structure without mold are described. As for an appropriate material for the system, fiber reinforced mortar was selected by experiments on compressive strength, fluidity, viscosity and setting time. By performing transfer and extrusion experiments, the possibility of the development of deposition construction system was demonstrated. Based on this research results, it is required to keep the automatic deposition construction system improve and extend it into the new application area in construction industry.

Purpose : This study was performed to determine the rate of neonatal symptomatic spontaneous pneumothorax, and the corresponding clinical characteristics, co-morbidities, and outcomes. Methods : The demographic characteristics, clinical symptoms and signs, associated abnormalities, methods of treatment, and outcomes were investigated in 22 neonates with symptomatic spontaneous pneumothorax in the neonatal intensive care unit (NICU) of Chonnam University Hospital between March 2003 and February 2008. Results : The rate of spontaneous pneumothorax was 0.55%. Among the 22 neonates, the number of outborns was 15 (68.2%) and the number of males was 12 (54.5%). The main symptoms and signs were chest retraction, tachypnea, and cyanosis. The pneumothoraces were more frequent on the right side (59.1%) and all cases were diagnosed within 3 days of life. Four cases (18.2%) had urologic abnormalities and 7 cases (31.8%) had cranial abnormalities by ultrasonography. The treatments included oxygen (81.8%) and oxygen with chest tube drainage (18.2%). All of the infants survived and the overall outcomes were favorable. Conclusion : When respiratory symptoms and signs are develop abruptly in otherwise healthy newborns, the clinician should suspect a spontaneous pneumothorax and check a chest x-ray as soon as possible. Although the outcome of neonatal symptomatic spontaneous pneumothorax is favorable, renal and cranial ultrasonography are needed because of the higher possibility of urologic abnormalities and germinal matrix/intraventricular hemorrhage than in newborns without a pneumothorax.

When a pregnant woman experiences cardiac arrest, resuscitation is of the utmost importance. Cardiac arrest in pregnant women differs from cardiac arrest in the general population since both mother and fetus need to be taken into consideration. In the event of cardiac arrest, determining whether to deliver the baby is significant. Cardiopulmonary resuscitation is not always successful, and the survival rate depends on the speed and precision of the procedure. In this study, we focus on the case of a 30-year-old pregnant woman who experienced cardiac arrest and whose family was quick to perceive her condition and call the hospital. A witness performed initial cardiopulmonary resuscitation, while rescue workers performed the advanced procedure. In this case, the patient and baby received proper treatment and left the hospital after six days. It is extremely rare for a pregnant patient to achieve return of spontaneous circulation (ROSC) or receive advanced cardiac life support before reaching the hospital. However, the woman in question in this study achieved ROSC and received both cardiopulmonary resuscitation before reaching the hospital and advanced cardiac life support at the hospital. The specifics of the case are reported in the context of a literature review.

노화는 모든 다세포 유기물의 특징이다. 노화가 됨에 따라서 효소활성 및 면역반응의 감소와 과산화지질과 지방갈색물질의 축적, 효소와 염색질을 포함하는 단백질 구조의 변화, 호르몬계의 불균형 등이 일어난다. 그렇지만, 노화가 어떻게 일어나는지에 관하여는 현재까지 확실하지 않다. 본 연구진은 노화와 관련된 효소들에 관하여 연구를 하여 왔으며, 노화가 진행되는 동안의 효소의 활성을 유지시켜주거나, 또는 효소의 활성이 감소되는 것을 지연시켜 주는 물질을 찾고자 노력하였다. 그 가운데 하나로서, 고려인삼 추출물을 흰쥐에 기간별로 투여하여 효소활성의 차이, 열에 대한 안정성, 기질에 대한 친화력, 전기 영동 상의 이동성과 면역적인 반응을 대조군과 비교하였다. Glucose-6-phosphate dehydrogenase, 6-phosphog-luconate dehydrogenase, glutathione redutease, glutathion peroxidase와 같은 노화와 관련된 효소들의 활성을 고려인삼 추출물을 1개월간 흰쥐에 ($60{\~}80$g)투여하여 대조군과 비교 조사하였으나, 별 차이가 없었다. 그러나 고려인삼 추출물을 15개월간 투여하였을 때에는 이러한 노화관련 효소들의 활성이 급격히 증가함이 ($70{\~}200\%$) 관찰되었다. 예견된 바와 같이, 효소의 열에 대한 안정성과 기질에 대한 친화력도 증가함이 관찰되었다. 그러나 glucose-6-phosphate dehydrogenase의 경우에서 전기영동상의 차이 및 면역적인 반응은 대조군과 유사하였다. 이상의 결과는 고려인삼 추출물이 노화와 관련된 효소들의 활성이 감소되는 것을 지연시켜줄 수 있으며, 노화를 어느정도 지연시켜 줄 수 있음을 의미한다. 이와 같은 결과를 포함한 실험자료를 국제 인삼심포지움에서 발표할 것이다.$-tocopherol의 항 산화작용을 더욱 효과적으로 촉진 시킬 것으로 생각된다.-L(독성 호르몬-L)의 작용을 억제함으로서 암환자의 체중 감소를 방지하고, 식욕감퇴를 개선할것으로 생각된다.해되었으며, $Rb_{1}$은 장내의 효소와 tetracycline-resistantant bacteria에 의해 Rd와 2 종류의 미확인 물질로 분해되었다.xA_{2}$ synthetase 억제제인 imidazole의 효과와 유사하였다. 4.
