메밀빵 개발에 사용된 강력분 70%와 외피함량이 적은 메밀가루 A와 외피함량이 많은 메밀가루 B 30%의 혼합분에 활성 글루텐과 gum물질(guar gum, xanthan gum)을 첨가했을 경우 첨가물에 따른 반죽의 물리적 성질을 조사하였다. Farinogram 특성치에서 메밀가루 A복합분은 수분 흡수율, 반죽 형성 시간, 안정도가 모두 감소하였고 약화도는 증가한 반면, 메밀가루 B 복합분은 수분흡수율과 약화도는 증가하고, 반죽형성시간과 안정도는 감소하였지만 메밀가루 A 복합분보다는 안정도와 약화도가 모두 크게 나타났다. 활성 글루텐 첨가로 수분 흡수율이 증가하였고 반죽형성시간은 길어지고 약화되는 정도는 감소하였다. 또한 안정도는 xanthan gum첨가로 다소 증가하여 활성 글루텐 첨가시보다 오히려 높았다. Extensogram특성치에서 메밀가루 대체시에 신장성과 반죽의 강도는 감소하였고 특히 메밀가루 B 복합분이 신장성이 낮게 나타났다. 신장에 대한 저항도는 메밀의 외피함량에 따라 차이를 나타내어 메밀가루 A 복합분에서는 감소하였으나 메밀가루 B 복합분은 반대로 현저한 증가가 나타나 반죽이 경직되는 경향을 보였다. 그러나 활성 글루텐의 첨가로 신장성은 증가하였고 신장에 대한 저항도는 감소하여 메밀을 함유한 반죽 물성이 개선되었다. Gum물질 첨가만으로는 메밀빵 반죽 물성을 개선할 수 있는 신장성에 대한 효과는 나타나지 않았다.

The purpose of this study was to demonstrate the effect of music therapy as a nursing intervention on changes in recovery of consciousness and vital signs for postoperative patients in the recovery room. The subject for this study were fifty three of postoperative patients who were transferred from the OR to the RR at Kwangju Christian Hospital in Kwangju City. Thirty of them were assigned to the experimental group, and twenty three, to the control group. The age of the subject was between twenty and sixty years of age. The subject had a general anesthesia without any special complications, and they were not completely awake. The data were collected for six months from July 1999 to February 2000. The method used was to compare the condition of the subjects in each group at the beginning and at certain times repeatedly. The features observed were the level of consciousness, the frequency of complaints of pain, and vital signs of the subject before and 15 minutes, 30 minutes, and 60 minutes after hearing their favorite music for 30 minutes. The results are as follows 1. The recovery of consciousness was revealed through significant changes in facial expression, facial color, and grip strength in the experimental group more strongly than in the control group. No significant changes were shown in verbal order. The differences in recovery of consciousness in the pre-post music therapy between the two groups was not significant in verbal order, facial expression, or grip strength. However, significant changes were seen in facial color. 2. There were no significant differences between the two groups in changes in the frequency of pain complaints after music therapy. However, a significant difference was shown in the pre-post music therapy scres. 3. Vital signs did not show a significant difference between the two groups. However, the $SPO_2$ of the experimental group was significantly elevated after 60 minutes. The difference pre-post to the music therapy in the vital signs between two groups was significant only in body temperature. This study showed that the effect of music therapy given to postoperative patients is that it promotes changes in facial expression, facial color, and grip strength helping recovery of consciousness, stabilizing vital signs, elevating levels of $SPO_2$. and reducing complaints of pain. It is recommended that if the patient wants it music therapy be given right after surgery in the recovery room as a nursing intervention.

Purpose: The purpose of this study was to compare the difference of change in oxygen saturation, vital signs and suction time taken for the suctioning during endotracheal suctioning performed with closed suction system and with opened suction system. Methods: Data were collected from 31 adult patients with ventilator treatment who were admitted to a university hospital in Seoul and the collection period was from July 1 to November 15, 2005. Oxygen saturation, heart rate, respiration rate and mean arterial pressure were collected immediately prior to the suctioning intervention, during and 1 and 5 minutes after the suctioning from opened suction system and closed suction system. Results: 1) The difference in oxygen saturation was statistically significant in recovery time for oxygen saturation to return to baseline values after suctioning was significantly rapid on closed suction system (p<.05). 2) The difference in heart rate, respiration rate and mean arterial pressure was statistically insignificant 3) The suction time was shorter in closed suction system. Conclusion: Closed suction system is more efficient, as compared with the open suction system in the ventilator treatment.

Purpose: Stable vital signs (SVSs) are thought to be the most important criteria for successful non-operative management (NOM) of blunt spleen injury (BSI). However, a consistent definition of SVSs has been lacking. We wanted to evaluate the diversity of the definitions of SVSs by using a nationwide survey. Methods: A questionnaire regarding the definition of SVSs was sent to the trauma surgeons working at the Department of Trauma Surgery and Emergency Medicine at a level-I trauma center between October 2011 and November 2011. Data were compared using analyses of the variance, t-tests, ${\chi}^2$ tests and logistic regressions. Results: Among 201 surgeons, 198 responded (98.2%). Of these 198 responses, 45 were incomplete, so only 153 (76.1%) were analyzed. In defining the SVSs, significant diversity existed on the subjects of type of blood pressure (BP), cut-off value for hypotension, technique for measuring BP, duration of hypotension, whether or not to use the heart rate (HR) as a determinant, cut-off value of hypotension when the patient had a comorbidity or when the patient was a child. Of the 153 surgeons whose responses were analyzed, 91.5% replied that they were confused when defining SVSs. Conclusion: Confusion exists regarding how to define SVSs. Most surveyed surgeons felt that a need existed to clarify both the definition of SVSs and the use of SVSs to determine hemodynamic stability for NOM.

The purpose of the study is to construct a life table for population. It is based on the fraction of last year of life, $a_X$. The data necessary for this purpose have been obtained from the 1975 Population Census Report of Korea and the Vital Statistics of Shindong-myon, Chunseong-gun, Gangwon Province which is collected for the Seoul National University public health program. Age specific death rate is adapted by the Model Life Table, West, Level 21. For the age groups of less than 5 years of age, when the record of vital events can be obtained, the fractions are calculated from the community vital statistics. And for the age groups older than 5 years of age, Greville's Method is used. The findings are summarized as follows: 1) The fraction of last year of life in infantile group is 0.3684 for males, 0.3711 for females, and in 1-4 years of age group 1.2164 for males, 1.2274 for females. Both are more than those of Japan and U.S. in 1963. 2) Infant mortality rate is 42.37 for males, 31.77 for females per 1,000 live births. 3) The mortality curves show that a higher rate is observed under 1 year of age. It drops to the lowest point at around 10 years of age and rises again as the age increases. 4) The age estimated half-survival rate is during the age group of 70-74 for both sexes. 5) Life expectancy at the age of 0 shows 65.73 years for males and 69.22 years for females.

Purpose: The purpose of this study was to investigate whether the respiratory function of patients with stroke was different on the ground and under water. Methods: We recruited 14 adults who had experienced a stroke (12 male, 2 female) for our study. We measured forced vital capacity, forced expiratory volume at one second, maximum inspiratory pressure, and maximum expiratory pressure when the participants breathed on the ground and under water. On the ground, the participants were safely supported using a table and chair and were measured in a standing posture. For measuring under water, the participants were immersed in water in a standing position to clavicle height. The participants were measured while standing, and the assistant supported them when they needed help. The collected data were analyzed by a paired t-test. Results: Forced vital capacity and forced expiratory volume at one second were significantly lower in water than on the ground when breathing at maximum. Maximum inspiratory pressure was not significantly different when standing on the ground or in water, but maximum expiratory pressure was significantly higher in water than on the ground. Conclusion: It has been confirmed that the hydrostatic pressure affecting stroke patients immersed in water affects the forced expiratory volume at one second while reducing the forced vital capacity and increasing the maximum expiratory pressure.
