The purpose of this study was to determine the association between school administrator support as perceived by nutrition teachers (dietitians) and job satisfaction in order to provide data concerning efficient job performance of nutrition teachers, to determine effects of school administrator support on job satisfaction in nutrition teachers, and to provide basic data that could help improve school meals. Major supporters of nutrition teachers (dietitians) were chief administrators (55.3%), principals (27.2%), assistant principals (15.0%), and managers in charge (2.4%). Nutrition teachers (dietitians) scored 3.38 for perception of school administrator support, 3.66 for emotional support, 3.27 for informational support, 3.22 for instrumental support, and 3.11 for evaluation support. Support of nutrition teachers (dietitians) by school managers included emotional support (3.66)>informational support (3.27)>instrumental support (3.22)>evaluative support (3.11). Nutrition teachers (dietitians) scored 3.37 for job satisfaction, as follows: work performance (4.19)>interpersonal relationships (3.39)>job satisfaction in general (3.37)>job itself (3.29)>job environment (3.07)>performance rating and benefits system (2.70). Statistically significant correlation was observed between perception of school administrator support and job satisfaction (r= .771, p< .01). Therefore, school administrators are necessary to provide evaluative supports to nutrition teachers (dietitians), performance assessment, employee benefit packages, and improvement of school meal plans and quality.

This study was conducted to analyse the current clinical education of pediatric nursing in baccalaurate nursing program, then to give basic data for enhancing the quality of future clinical education of pediatric nursing. Data were collected through self-reported questionnaire by mail from December 2001 to February 2002. The subjects were 29 schools of 50 baccalaurate nursing education programs. The data were analysed by double raters, researcher and assistant researcher. The results were summarized as follows: 1. Twenty-eight schools had the objectives of the clinical education of pediatric nursing, and 28 schools in pediatric ward, 23 schools in nursery, 22 schools in neonatal intensive care unit(NICU), 15 schools in objectives related to profession by clinical site. 2. Credits on clinical education of pediatric nursing were most 15 schools of 3 credits. 3. The clinical sites were mainly the hospital that sick children were admitted in. 4. The clinical teacher were 9 types including pediatric professor and field nurse. 5. On teacher's role, the professor instructed the case study and conference, and field nurse instructed the patient assignment and nursing procedures. 6. All of schools used explanation and conference as a method of clinical education, 1 or 2 schools used PBL or role play or field study. 7. On clinical education content, most of school included Apgar scoring system, physical examination in newborn assessment, respira- tion maintenance, temperature maintenance, infection prevention, nutrition, and bath in newborn care. 8. On clinical education content, most of school included care of incubator, phototheraty, infusion, gavage feeding and how to use the instruments in NICU. Eighteen schools included attachment promotion, and 20 schools case study. 9. On clinical education content, most of school included a checklist of nursing procedures, case study, assessment of growth and development in pediatric ward and other sites. 10.There were various evaluation types in scores, measuring items. In conclusion, the results of this study revealed that there were some discrepancy in the objectives and contents, clinical sites on hospital focused, teacher's role, and diversity of measurement items and ratings in clinical education of pediatric nursing. There is a need for a standardization of content, clinical site, and evaluation tool to improve a quality of clinical education of pediatric nursing based on this study.

Viewed from the framework of world system, international migration is connected sometimes to unequal power relations by prejudice and discrimination in destination areas, or to equal power relations by intentional effort for harmonious multiculturalism. According to the existing ethnic relation theory, assimiationism, it is natural that ethnicity is fading away as the foreign immigrants of different ethnic background have long limed in a destination area, and thus the relative urban ethnic places are weakened and finally dissapeared. Through the various examples particularly on the United States, however, ethnicity would not be easily fading-away but be sustained for long time. Also, the characteristics of ethnicity or ethnic place are sometimes reivented or reconstructed as the various situation of multiculturalism is affected by postmodernism. Whether it is the thing made by ethnic segregation or by ethnic congregation, ethnicity and ethnic place are evidently a kind of affluent resources of culture and economy in the destination areas.

In this paper, we considered the scenario that one cellular link and muti-D2D links share the same frequency resource which can improve the spectrum efficiency during uplink communication in LTE (Long Term Evolution)-Advanced network. In order to reduce the interference caused to the D2D users, we set DME (Discovery and Management Entity) which can send the area information to eNB(evolved Node B). We proposed a resource allocation scheme by using these assistant devices to reduce the interference that CUE (Cellular User Equipment) causes to DUE Rx (D2D UE Receiver). Basing on the area information, in order to mitigate the interference among the D2D pairs which share the same frequency resource, a power control scheme has been proposed. The simulation results prove that by using the DMEs, the proposed schemes improve the stability of D2D communication and bring the highest performance of the communication system when comparing to the other different schemes.

The person who gets a ALS(Amyotrophic Lateral Sclerosis) has language disability and physical disability together. A common first symptom is a painless weakness in a hand, foot, arm or leg, which occurs in more than half of all cases. Other early symptoms include muscle weakness of speech. In the early stage of this disease they can communicate with other persons, but it will become increasingly difficult. In our research we have designed and implemented communication tools for them. We have implemented Chunjiin(the Korean computer keyboard) at PDA(personal digital assistant). And we have also implemented software which is consisted of frequently used words.

원자층 증착(Atomic Layer Deposition: ALD) 방법은 반응물질들을 펄스형태로 챔버에 공급하여 기판 표면에 반응물질의 표면 포화반응에 의한 화학적 흡착과 탈착을 이용한 박막증착기술이다. ALD법은 박막의 조성 정밀제어가 쉽고, 파티클 발생이 없으며, 대면적의 박막 증착시 균일성이 우수하고, 박막 두께의 정밀 조절이 용이한 장점이 있다. 원자층 증착 공정에서 짧은 시간 안에 소스를 충분히 공급하기 위한 방법으로는 소스 온도를 증가시켜 전구체의 증기압을 높여 반응기로의 유입량을 증가시키는 방법, 전구체의 공급시간을 늘리는 방법 등을 들 수 있다. 그러나 전구체 온도를 상승시키는 경우, 공정 조건의 변화가 요구되며 전구체의 변질에 의하여 형성된 막이 의도하는 막 특성을 만족시키지 못하게 되는 문제점이 발생될 우려가 있다. 그리고 전구체를 충분히 공급하기 위하여 전구체의 공급시간을 늘이는 방법을 사용하면, 원하는 두께의 막을 형성하기 위하여 소요되는 공정시간이 증가된다. 이를 해결하기 위해 수송가스를 이용한 버블러 형태의 전구체 공급 장치를 사용하지만 이 또한 전구체의 수명을 단축시키는 단점을 가지고 있다. 본 논문에서는 위의 문제점을 극복할 수 있는 새로운 개념의 수송가스 도움 전구체 공급 장치를 소개한다. 본 연구에서 사용된 수송가스 도움 전구체 공급 장치를 가지는 ALD 장비는 Lucida-D200 (NCD Technology사)이며 기판으로는 8인치 실리콘 웨이퍼를 사용하였으며 (TEMA)Zr을 사용하여 ZrO2 박막을 성장하였다. 수송가스 도움 전구체 공급 장치를 사용한 경우, 그렇지 않은 경우 보다 $30^{\circ}C$ 이상 전구체 온도를 낮출 수 있으며, 또한 증착 속도를 약 2배정도 증가시킬 수 있었다. 이들 박막들은 XRD, XPS, AFM 등을 이용하여 결정구조, 결합에너지, 표면 거칠기 등의 특성을 관찰하였다. 그리고 C-V, I-V 측정을 이용해 정전용량, 유전율, 누설전류 등의 전기적 특성을 평가하였다.

Electroencephalography (EEG) provides the most accurate and quickest diagnosis of epilepsy. It is also an important examination for the real-time evaluation of brain function and seizures, no matter where. In the field of epilepsy, it is appropriate for a clinical pathologist with considerable knowledge of EEG and clinical experience to perform the role of a Physician Assistant (PA). The electrode attachment method is based on the international 10-20 system. The EEG reading is mainly taken by longitudinal bipolar montage. However, a reading using only one montage may result in an error. Hence, two or more montages should be used for readings according to the clinical situation. In the EEG, electric potentials are seen as contour lines. The most important principle in EEG reading is under-reading, not over-reading. The higher the repetitions of the EEG recording, the greater the sensitivity of the reading. For a good reading, the EEG recording must be of good quality. So, the relationship between the neurologist and the EEG technician is very important. In the future, it is expected that the field of activities of the EEG technician with abundant EEG reading experience and clinical practical knowledge will be further expanded.

The purpose of this study is to identify the factors that may affect the 5-year survival of colon cancer through network model and to use it as a clinical decision supporting system for colorectal cancer patients. This study was conducted using data from 2,540 patients who underwent colorectal cancer surgery from 1996 to 2018. Eleven factors related to survival of colorectal cancer were selected by consulting medical experts and previous studies. Analysis was proceeded from the data sorted out into 1,839 patients excluding missing values and outliers. Logistic regression analysis showed that age, BMI, and heart disease were statistically significant in order to identify factors affecting 5-year survival of colorectal cancer. Additionally, a correlation analysis was carried out age, BMI, heart disease, diabetes, and other diseases were correlated with 5-year survival of colorectal cancer. Sex was related with BMI, lung disease, and liver disease. Age was associated with heart disease, heart disease, hypertension, diabetes, and other diseases, and BMI with hypertension, diabetes, and other diseases. Heart disease was associated with hypertension, diabetes, hypertension, diabetes, and other diseases. In addition, diabetes and kidney disease were associated. In the correlation analysis, the network model was constructed with the Network Correlation Coefficient less than p <0.001 as the weight. The network model showed that factors directly affecting survival were age, BMI levels, heart disease, and indirectly influencing factors were diabetes, high blood pressure, liver disease and other diseases. If the network model is used as an assistant indicator for the treatment of colorectal cancer, it could contribute to increasing the survival rate of patients.

Purpose: Intracorporeal esophagojejunostomy during reduced-port gastrectomy for proximal gastric cancer is a technically challenging technique. No study has yet reported a robotic technique for anastomosis. Therefore, to address this gap, we describe our reduced-port technique and the short-term outcomes of intracorporeal esophagojejunostomy. Materials and Methods: We conducted a retrospective review of patients who underwent a totally robotic reduced-port total or proximal gastrectomy between August 2016 and March 2020. We used an infra-umbilical Single-Site^® port with two additional ports on both sides of the abdomen. To transect the esophagus, a 45-mm endolinear stapler was inserted via the right abdominal port. The common channel of the esophagojejunostomy was created between the apertures in the esophagus and proximal jejunum using a 45-mm linear stapler. The entry hole was closed with a 45-mm linear stapler or robot-sewn continuous suture. All anastomoses were performed without the aid of an assistant or placement of stay sutures. Results: Among the 40 patients, there were no conversions to open, laparoscopic, or conventional 5-port robotic surgery. The median operation time and blood loss were 254 min and 50 mL, respectively. The median number of retrieved lymph nodes was 40.5. The median time to first flatus, soft diet intake, and length of hospital stay were 3, 5, and 7 days, respectively. Three (7.5%) major complications, including two anastomosis-related complications and a case of small bowel obstruction, were treated with an endoscopic procedure and re-operation, respectively. No mortality occurred during the study period. Conclusions: Intracorporeal esophagojejunostomy during reduced-port gastrectomy can be safely performed and is feasible with acceptable surgical outcomes.

Billiards is a fun and popular sport, but both route planning and cueing prevent beginners from becoming skillful. A beginner in billiards requires constant concentration and training to reach the right level, but without the right motivating factor, it is easy to lose interests. This study aims to induce interest in billiards and accelerate learning by utilizing billiard path prediction and visualization on a highly immersive augmented reality platform that combines a stereo camera and a VR headset. For implementation, the placement of billiard balls is recognized through the OpenCV image processing program, and physics simulation, path search, and visualization are performed in Unity Engine. As a result, accurate path prediction can be achieved. This made it possible for beginners to reduce the psychological burden of planning the path, focus only on accurate cueing, and gradually increase their billiard proficiency by getting used to the path suggested by the algorithm for a long time. We confirm that the proposed AR billiards is remarkably effective as a learning assistant tool.
