  • The unit curtain wall is an exterior finish currently used on the exterior walls of high-rise buildings. Although the structural impact is not significant due to the non-strength wall, in the case of the unit curtain wall to which the factory manufacturing method is applied, deformation of the profile may occur according to its own weight. Therefore, in this study, stability is evaluated through design standard calculation applied when finishing the outer wall according to the design shape of the unit curtain wall profile.

  • The epidemic of 2019 novel coronavirus, later named as coronavirus disease (COVID-19), began in Wuhan, China in December 2019 and has spread rapidly worldwide. Early diagnosis is crucial for the management of the patients with COVID-19, but the gold standard diagnostic test for this infection, the reverse transcriptase polymerase chain reaction, has a low sensitivity and an increased turnaround time. In this scenario, chest computed tomography (CT) could play a key role for an early diagnosis of COVID-19 pneumonia. Here, we have reported a confirmed case of COVID-19 with an atypical CT presentation showing a "double halo sign," which we believe represents the pathological spectrum of this viral pneumonia.

  • Unit price of meal provision in industrial foodservice differs with each business. It is believed that menu management work, contents of menu, and nutrition supply performed by dietitian are different with unit price of meal provision. In this sense, purposes of this study are to examine meal management work and contents of menu, by food cost, at industrial foodservice in Taegu, Kyungbuk area and to evaluate variety of menu and nutrition supply. Results of the study are as follows: 1. Average number of side dishes provided at meal, including Kimchi, was 2 at low unit price, 3.0 at middle unit price and 3.1 at high unit price. 2. Possession ratio of account books using for menu management was low. 3. With regard to kind of menu, high unit price was most various and showed more various, compared to low unit price, especially in cooking oil-used cook methods such as broil, pan-fried food, fry, and roast. 4. High unit price was found as the highest in kind of used food and supply volume. 5. Sugar, Mineral, Vitamine, and Protein were satisfied with standard food content, but fat and calcium were not. 6. Supply volume of food was positively correlated to supply volume of nutrient, but kinds of cook methods and food type were not correlated to that of nutrient.

  • The purpose of this study was the acquisition of the optimum scale of the apportionment of standard & high-class bed for the maximum profit representative of the desire of customers in a General Hospital with 1,100 beds located in Seoul. This investigation was proceeded by the analysis of the result of the simulation with the survey of both the patients' needs for bed and the degree of the medical service by the grade of the ward. And finally the consequence was obtained as follows: 1. The result of the investigation of the inpatients' preference for the grade of ward classes shows that a private ward reflected 4.3 percent, a semi-private ward 1.7 percent, a three-bed ward 0.1 percent, and a ward with six beds 93.9 percent each other. 2. A questionnaire poll was paralleled of service terms of a medical doctor and a nurse by ward class, the data were used for the standard of the allotment of labor cost by the ward class. The poll shows that the service tenn of a medical doctor and a nurse based on a ward with six beds by ward class showed 1.7 times in internal medicine and 1.9 times in surgery at a private ward; 1.4 times in internal medicine and 1.7 times in surgery at a semi-private room; and 1.2 times both in internal medicine and in surgery at a three-bed ward 3. The resultant findings revealed the most profit per bed and per patient in a private ward. However, an analysis of profit with a standard of unit area by ward class represented a higher profit in both the internal medicine and the surgery semi-private ward than other ward classes. 4. The result of the analysis through simulation based on the data of the prime cost per the ward class proved the optimum scale of the distribution of beds by class as follows: sixteen beds of the internal medicine and twenty three beds of the surgery in the private ward; two hundreds and two of the internal medicine and one hundred and ninety eight of the surgery in the semi-private room; three of both the internal medicine and the surgery each other in the three-bed ward; one hundred and ninety eight of the internal medicine and two hundred and fifty two of the surgery in the ward with six beds. The result of this research exhibits that the income and expenditure of the hospital could be improved by changing parts of wards into private ones(containing the maximum profit per a unit of width) in case the scale of the number of beds is reset with the consideration of the profit per the unit width. In the near future it's strongly expected that the research for the more scientific standard of the allotment of labour cost by ward class and for definition of the optimum scale of the number of beds that actualize the maximum profit with the change of the three elements of the prime cost: cost of materials; labor costs; management expenses.

  • 표기 체계인 한글을 한국어 음가로 변환하는 음운변동 규칙을 역으로 적용하여, 한국어 음가를 한국어를 표기하는 문자 체계인 한글로 전환시키는 규칙을 고안하는 것이 본 연구의 목표이다. 제정된 규칙은 한국어 음성인식에 있어서 매우 귀중한 역할을 담당한다. 일반적인 음성인식 기법은 수회의 학습과정을 통하여 추출된 음성의 표준패턴과 인식 대상으로 입력된 음성을 비교하여 가장 유사한 패턴을 찾는 방법을 사용한다. 이 때 표준 음성패턴이 띄어쓰기 단위의 어절이라면 수백만 개의 표준 패턴이 수록되어야 하므로 표준패턴을 위한 방대한 데이터베이스의 구축은 물론 표준패턴과의 비교 회수도 너무 많아져서 실용화가 불가능하다. 이에 대한 대안인 음절 단위 인식의 경우는 인식된 음가가 실제의 한글 표기와 맞지 않으므로, 인식된 결과를 출력할 때에 실제의 한글표기로 변환해 주어야 하는 과제를 안게 된다. 이 과제를 해결하는 과정, 즉 일련의 한국어 음가들을 일련의 한글 표기 문자로 바꾸어 주는 과정에서는 본 논문에서 제안한 표준 한국어 음가 - 표기 문자 변환 규칙을 적용할 수 있을 것이다. 본 논문에서는 새롭게 제안된 표준 한글 음가-표기 문자 변환 규칙을 사용하여 한국어 음가를 한글 표기로 변환하는 시스템을 구현하였다. 그리고, 고안된 규칙의 무결성을 보이기 위하여 표준 발음규칙 30항을 반영하는 데이터 집합을 이용하여 구현된 시스템을 시험하였으며, 그 실험 결과를 제시한다.

  • Purpose: The purpose of this study was to develop the adapted standard items of situation, background, assessment, recommendations (SBAR) processing for handover between nursing units in Korean hospitals and evaluate the validity and relevance of the standard items. Methods: A delphi method with 33 experts was used to evaluate content validity of the standard items. Then, 1,175 nurses working in general hospitals of more than 500 beds were recruited to evaluate the validity and relevance of the standard items for clinical implication. Results: Content validity was higher than 0.8. The highest scores for relevance among items in handover standards were state of consciousness in the assessment domain for a ward to a ward transfer ($3.82{\pm}0.40$), for a ward to an ICU ($3.85{\pm}0.38$), an ICU to a ward ($3.81{\pm}0.39$) and an ER to a ward ($3.85{\pm}0.37$). Congenital malformation was the highest relevance score for handover from a delivery room to a neonatal unit ($3.91{\pm}0.30$). Conclusion: This study evaluated validity and relevance of the essential contents for handover standards between units to improve communication quality among nurses. The findings of this study should also be applied in clinical nursing areas and the quality of information and effectiveness of usage of the standard should be evaluated.

  • $pH=-loga_H$ 정의에서 pH는 단일 이온의 활동도항을 포함하므로 단지 측정의 방법만으로는 결정되어질 수 없고 근사법을 필요로 한다. 근사법에 의한 pH 측정은 수소전극과 은/염화은 전극을 사용한 액간 접촉이 없는 cell의 기전력 측정으로부터 이루어지는 방법이며, 이 과정을 통해 pH 값이 인증된 pH의 일차 표준 물질을 얻을 수 있다. 일반적인 pH 미터와 전극을 검정하는 데에는 인증된 pH 값을 가지는 표준 완충용액을 사용하므로 표준 완충용액의 pH 값 정혹도는 실제 측정된 pH 값의 실효성을 제한할 수 있다. 본 연구에서는 정확한 pH의 측정을 위해서 pH 값을 인증할 수 있는 시스템을 구축하기 위한 제반의 연구를 수행하였으며, 이를 토대로 pH 1.6∼12.5의 범위에 해당하는 완충용액의 pH를 0.005 pH 단위 이내의 불확도로 인증하였다.

  • The Purpose of this study is to examine closely the causes influenced upon the comfort and recovery of the woman delivered of a child in the hospital at the same time to understand environmental status of hospitals in order to promote mother's health recovery, and to improve hospital environment by emphasizing the meaning of environment and health before the medical staff and hospital administrative authority. In the method of servery of the research, 165 post paestum patients have been randomly selected who were accommodated and delivered their babies at OB(obstetric ) & GY (Gynecologic) unit the 7 general hospitals for the period of 6 December 1976 through 17 December 1976. As for the survey, it has been used of Questionnaire where we have 65 items in the respect of personal environment in the hospital such as trusting nurse, ability, reliability, kindness and etiquette of nurse and tile character of nurse the relationship with patients the other respect of physical environment included 9f temperature, moisture. air-ventilation lightening noise, cleanness. facilities, and the third realm being of mother's hearth ground to have the following conclusion 1. The feature of the collected personnel they are from OB or GY sects of from OB unit of the other 5 hospitals except the two general hospitals of the college or school Otherwise the rate of the patients to nurses would be 9 : 1. As for the nurses'ground it would be appeared of 20-25 years of age as the 76%. either 3 year course or 4 year course in the education would be each 50% and less than 2 year experience case would record as of 60 %. In the respect of hospital physical environmental status, there we have two hospitals without any thermometers, on the other han4 nowhere there's hygrometer, otherwise, the lightening is normal or over than normal As for the structure of noise protection the corridors're, generally speaking worse than rooms, nerver hueless, there's no ventilating system in the hospitals. The rooms'repainted in white and yellow, light green white, or green color. The patient's clothing were in green pink blue, light green or in white co for. There're not anything special in both decoration and equipments. Most of them used tall beds except in one hospital 2. To the extent of perception of patient's hatch 9round and hospital environment it is presented that they perceived nurse's ability in highest in total human variable, though perceived kindness or etiquette in the lowest otherwise, comparatively high in total average. 3. In the respect of physical environment it is highest perceived of lightening terms, otherwise, lowest perceived of air ventilation and total average became lowest than the one of the original record 4. To ages, in the respect of hatch ground rather old aged mother than the younger one has perceived that nurse would be trusting, in good service character, able, at the same time, liable, Otherwise, in physical environment regardless of age, they perceived lightening in high and remarkably lower in ventilation As a result of the examination of the difference in hospital environment to each age it is appeared of statistical difference at 5% level of ability in the personal environment otherwise little difference as for physical environment 5. In the respect of perceiving level to educational standard it is highly perceived of personal environment for higher ranking group rather than lower group in the educational standard. In case of physical environment it is highly perceived for lower level group rather than higher level group in educational background. The variables which have statistical significance at 5% level are from trusting kindness, etiquette and total kindness, etiquette and total all significance at 5% level are from trusting, kindness, etiquette and total human environment variable in personal environment, otherwise, there's little difference in the physical environment. 6. The perceiving level due to times of admission and accommodation at the hospital would be cleared out as gradual higher perception both physical and personal environment in the hospital. At 5% significant level of the ventilation condition in physical environmental variable it is presented of meaningful difference otherwise, there we have little difference both in Personal variable and other one. 7. In accordance with living standard, the perception degree of personal environment in tee hospital would be inclined to increase to higher living standard on the other hand, in case of the physical environment, the perception level world increase to lower living standard At 5 % level, the trustuariable and total scores in the personal eicuironmectal variable there appeared a meaningful/ significant difference otherwise, there presented little difference both in physical environmental and other variable to the living standard 8. Pertaining to family unit, the mother of an independent family unit perceived highly in all respect of the personal and the physical environment in the hospital rather than the woman of succeeding family unit. At 5 % level there appeared a difference in the respect of kindness and etiquette both in personal environment variable, on the other hand, there hardly marked a difference between other variable and physical environmental one. 9. The degree of perception to comforting level has little connection with a statistical difference the age, educational level hospital admitting times, living standard or family unit. 10. The most effective variable to mother's comforting level will be nurse's ability, reliability, trusting manner, and total physical environment variable in order.

  • The current dual-watchdog estimation system has individually calculated the construction, the engineering and the procurement cost. The dual-watchdog estimation system is inefficient and prolonged estimation period because of the lack of the interoperability and the difference of material unit cost and construction unit cost. In order to resolve this problem, new estimation software was developed. The estimation software is developed by making up for the weak points in existing estimation method. The cost data with the same standard is the key point. And this software enhanced accuracy and speed of the data search in stylized estimation standard. A summary of the construction, the engineering and the procurement cost was generated in this estimation software. The unit rate about the labor cost, equipment and expense through a sheet was handled. The developed estimation software has five categories on engineering cost, procurement cost, construction cost and subcontractor management sheet. In this study, the estimation software to supplement the faults of the existing estimation method was developed. And estimation software on petrochemical projects increases an efficiency of the estimation work.
