The aim of this study is to analyze the complementizer that-deletion in embedded complement clauses in English. This paper is concerned with the alternation between the overt that-complementizer and the zero complementizer by the complementizer deletion (C-deletion or that-deletion) in constructions with a nominal complement that-clause, i.e. [VP Verb [CP that-TP]]. In this paper, we compare that-complementation and zero-complementation in a diachronic grammaticalization and corpus, and show that the complementizer that has its origin in pronouns diachronically and finally becomes to form a C-head of the functional category CP. We provide the syntactic and semantic explanation on the optionality of that-deletion while answering the question why and how that-deletion is getting increasing in use especially with the verb, think, in the informal contexts. With the major causes for the currently increasing use of that-deletion, we are concerned with the contexts in which the overt complementizers or the covert complementizers are preferred.

2006년 1월 9일부터 시행되고 있는 주택 성능 등급 표시제도는 능동적(Active)대책으로서의 인명안전 확보에 대해 어느 정도의 등가성을 확보 할 수 있는 소방시설의 품질 및 성능 향상에 관한 내용을 포함하는 것으로 화재 안전의 확보차원에서 매우 바람직한 방향의 정책이라 보여 진다. 본 연구는 현재 국내에서 시행되고 있는 주택성능등급 표시제도의 항목 중 "화재-소방" 분야의 등급시행 활성화를 위해 각 성능 등급 분야에 대한 이론적 배경을 고찰하고 세부 평가 방식에 대한 합리적 개선점을 도출하기 위해 수행되었다. 연구 결과, 현행 주택 성능등급 제도에 따른 "화재-소방" 분야의 성능 향상을 위해서는 성능 등급 세부 항목에 대한 배점 기준을 상향시키는 제도적 정부 시책이 우선적으로 뒷받침 되어야 하고, 아울러 소방 관계법 규정의 시급한 관련 법규 제정이 필요 하다는 전제조건이 선결되어야함을 알 수 있었고, 이를 바탕으로 현행 세부 평가기준에 대한 개선안을 제시하였다.

상완골 근위부 골절은 상완골의 외과적 경부 또는 근위부에 발생하는 골절로 정의할 수 있으며, 적절한 치료에도 불구하고 다양한 합병증 및 후유증이 발생할 수 있어 그 치료가 매우 까다롭고 견관절 치환술 등의 수술적 치료를 요하는 경우가 많다. 상완골 근위부 골절 후 후유증은 Boileau가 제시한 분류법이 가장 많이 사용되며, 2개의 카테고리 및 4가지의 타입으로 분류할 수가 있다. 카테고리 I은 관절 내 감입 골절로 결절들과 상완골 두 사이에 저명한 해부학적 변형이 동반되지 않아 결절 절골술을 시행하지 않고도 해부학적 치환물을 사용할 수 있는 경우로서 결절의 불유합이 거의 없이 두경부의 붕괴(cephalic collapse)나 괴사가 있는 타입 1과 잠김 탈구(locked dislocation) 또는 골절-탈구와 관련이 있는 타입 2로 나눌 수 있다. 카테고리 II는 관절 외 골절이며 결절들과 상완골 두 사이에 육안적인 변형이 있는 경우로서 해부학적 치환물을 사용하기 위해서는 결절 절골술을 시행해야 하며, 외과적 경부의 불유합이 동반된 타입 3와 심각한 결절의 부정유합이 동반된 타입 4로 분류할 수 있다. 각 타입별 치료를 위해서 타입 1의 경우에는 결절 절골술을 시행하지 않고 비구속형 치환술을 우선적으로 고려해야 하지만, 타입 1C, 1D와 같이 외반이나 내반 변형이 동반되거나 회전근 개의 지방 변성이 심할 경우에는 역행성 견관절 전치환술 또한 고려해야 한다. 타입 2는 일반적으로 비구속형 치환술로 좋은 결과를 기대할 수 있으나 관절와 골 결손이 없으며 회전근 개의 결손이 동반된 경우 역행성 견관절 전치환술 또한 하나의 치료 방법으로 고려할 수 있다. 타입 3는 견관절 치환술보다는 골쐐기 이식 등을 함께 시행하여 내고정을 시행하는 것이 효과적일 것으로 보이며, 최근 역행성 견관절 전치환술의 결과에 대한 보고 또한 점차 증가하고 있는 추세이다. 마지막으로 타입 4는 역행성 견관절 전치환술이 우선적으로 고려되어야 할 것으로 보인다.

Scene graphs serve as semantic abstractions of images and play a crucial role in enhancing visual comprehension and reasoning. However, the performance of Scene Graph Generation is often compromised when working with biased data in real-world situations. While many existing systems focus on a single stage of learning for both feature extraction and classification, some employ Class-Balancing strategies, such as Re-weighting, Data Resampling, and Transfer Learning from head to tail. In this paper, we propose a novel approach that decouples the feature extraction and classification phases of the scene graph generation process. For feature extraction, we leverage a transformer-based architecture and design an adaptive calibration function specifically for predicate classification. This function enables us to dynamically adjust the classification scores for each predicate category. Additionally, we introduce a Distribution Alignment technique that effectively balances the class distribution after the feature extraction phase reaches a stable state, thereby facilitating the retraining of the classification head. Importantly, our Distribution Alignment strategy is model-independent and does not require additional supervision, making it applicable to a wide range of SGG models. Using the scene graph diagnostic toolkit on Visual Genome and several popular models, we achieved significant improvements over the previous state-of-the-art methods with our model. Compared to the TDE model, our model improved mR@100 by 70.5% for PredCls, by 84.0% for SGCls, and by 97.6% for SGDet tasks.

Purpose: This study was to explore work experience among nurses with low back pain. Specific aims were to identify problems nurses face as workers at a hospital and how they interact with other workers. Methods: Grounded theory methodology was utilized. Data were collected from iterative fieldwork with individual in-depth interviews from 9 nurses with low back pain as key informants, and a head nurse and a charge nurse who had experiences working with nurses with low back pain as general informants. Results: Through constant comparative analysis, a core category emerged as "to make one's own ground". The process of "to make one's own ground" was identified as four categories: perception of limitations, intervening conditions, balancing limitations, and controlling limitations. Intervening conditions were identified as 'working conditions' and 'personal traits'. Conclusion: Findings of the study indicate that there is a need for health professionals and administrators to understand limitations to working experience among nurses with low back pain. In addition, institutional and psychological support program is needed to improve an adaptation to working environment among nurses with low back pain.

The purpose of this study is to identify the leadership and subordination of hospital nurses: to determine the leadership and subordination by nurses' characteristics, which are age, educational background, career, and position of nurses. 279 staff nurses, 13 charge nurses, 32 head nurses and 16 nurse supervisors were participated in this study during the period from Dec. 5 to Dec. 20, 1986. Subjects were instructed to rate at one of five points likert type scale on the 26 items of leadership and subordination. The reliability of the items (Cronbach's α) were 0.63∼0.84. Among the total 26 items, 8 items on authority, 4 items on human relation, 9 items on committment of position and 5items on committment of job were summed to cummulative scores in each category. As a result of data analysis nurses who perceive positive on authority are 68.6% and positive on human relation are 67.9%. The perception of authority is different by age, Career and position of nurses. (P<0.05). And nurses who perceive positive on committment of position are 84.7% and positive on committment of job are 62.1%. The perception of committment for position is different by age, career and position of nurses (P <0.05), and committment of job is different by age and position. (P<0.05).

Purpose: The purpose of this study is to provide the basic data for the ergonomic design of first-aid activity space(FAS) for a future ambulance suitable for the performance of 119 EMT. Methods: Questionnaire was filled out by the 124 EMT in 119 centers. The questionnaire consisted of 3 sub factors including the satisfaction and compatibility of the FAS. The satisfaction and compatibility was analyzed based on characteristics of the subjects. Results: The satisfaction rate of the FAS within the ambulance was an average of 2.23, and the compatibility category got an overall average score of 2.26. The lowest ranked criteria in the satisfaction and compatibility factor was the functionality of storage space showing 1.93 and 1.88, respectively. The best position of the paramedic seat was the top side of the patient, near the head, which is suitable for patient assessment and treatment. Conclusion: During patient transportation of 119 EMTs, for efficient work process, a layout design of the FAS should be based on ergonomics that satisfied the performance function.

We experienced one case of orthotopic cardiac transplantation in a patient with end stage dilated cardiomyopathy. This 50 year-old female recipient was suffered from NYHA functional class IV cardiac failure and dependent upon intravenous inotropic support for 2 months [recipient category 1]. Her preoperative condition was grave with left ventricular ejection fraction of 20% and estimated systolic pulmonary arterial pressure [from Doppler study] was 50mmHg. The brain-dead donor was 31 year-old male with head trauma. The body sizes [weight, height] of the donor/recipient were 70 Kg, 165 cm / 43 Kg, 160 cm and appropriately overmatched. Preoperatively, identical ABO/Rh blood group [A+] and nonreacting HLA crossmatching were confirmed. On November 11 1992 cardiac transplantation was performed without complication. Multiple organ procurement team and heart transplantation team were organized the operation schedule appropriately to minimize the ischemic time. The pump time was 126 minutes and aortic crossclamping time of recipient heart was 73 minutes and, as a result, total ischemic time of the transplanted heart was 75 minutes. Postoperatively, the vital signs were stable with minimal inotropic support. The immunosuppressive therapy was commenced from preoperatively and cyclosporine, azathioprine, and corticosteroid were used as a combination therapy as scheduled and monitored with blood drug concentration, WBC count, renal function and most importantly regular endomyocardial biopsy.Now, 5 months after transplantation, the patient is in NYHA functional class II with minimal cardiac drug support.

This study attempted to measure self-disclosure changes of nurses a result of human relations training. The study population consisted of 49 nurses in Seoul. The instrument used in this study was the Self-disclosure questionnaire developed by Jourard in 1958, was designed to measure verbalized aspects of self-disclosure defined as a voluntary act of revealing personal data about oneself including beliefs, values, feelings and perceptions to another person. The SDG instrument is devided into six areas: attitude, taste and interest, personality, money, work and body. The main findings were summarized as follows: 1. After training, the subjects disclosed more than before. 2. Subjects tended to very the amount of self-disclosure with respect to the category of information to which an item about the self belonged. Two clusters of aspects emerged, a high disclosure cluster including Attitude, Tastes and Interests, Personality and Work, and a low disclosure cluster comprised of Money and Body. 3. Before and after training, there was significant difference in the self-disclosure to the peer nurses. Subjects showed the highest self-disclosure to friend, with lesser amounts to patient. 4. Charge and head nurses showed the highest differences in self-disclosure resulting from human relations training.
