오존처리는 음용수중의 유해한 미생물을 소독하는 처리기술로 주로 이용되고 있으며, 생물활성탄 처리기술 역시 오염물질 제거를 포함한 음용수 제조과정에 여러 가지 이점을 제공한다. 이글의 병행처리는 원수중의 여러 물질을 제거하는데 효과적인 공정으로 간주되고 있다. 본 연구에서는 낙동강 하류의 매리취수장 원수를 사용하여 생물활성탄 정수처리공정 및 오존에 의한 수질 변화와 함께 폴리오바이러스 제거 효율을 조사하였다. 수질인자들은 BAC 여과를 거치면서 $NH^{+}_{4}-N$등을 포함한 모든 항목들은 거의 제거되는 것으로 나타났다. Pilot-plant를 이용한 정수처리공정별 폴리오바이러스 제거실험에서는 전오존 접촉에 의해 $96.8\%$, 침전단계에서$99.3\%$, 여과단계에서 $99.6\%$의 바이러스가 제거되었으며, 후오존을 거친 BAC 여과수 시료에서는 세포배양법과 ICC-PCR 방법에서 바이러스가 $100\%$ 제거되어짐을 확인할 수 있었다. 오존농도에 의한 폴리오바이러스 제거실험 결과 0.4mg/1에서 5분간 접촉되었을 때는 약 $61.1\%$ 이상이, 0.8mg/1에서 10분 이상 접촉시킨 후에는 바이러스의 $100\% $가 불활성화 되어졌음을 알 수 있었다. Ozonation is a disinfection technique of harmful mi-crobes commonly used in the treatment of drinking water. And Biological Activated Carbon (BAC) treatment also provides numerous benefits for drinking water utilities, including removal of micro- pollutants, improved treatment processes. The multiful-stage ozonation and BAC play roles as effective methods for removing several materials in raw water. Water quality variation in Nak dong river and the removal efficiency of viruses by ozonation-BAC process were investigated on pilot scale. During the period of survey, most of water quality parameters including $NH_{4}^{+}-N$ were highly improved after passing through the BAC. The removal efficiency of poliovirus type III in water treatment process using pilot-plant,$ 99.6\% $ of viruses were removed by pre-ozonation, sedimentation and sand filteration process, $ 100\% $ were removed after in BAC filteration step. In the removal survey of viruses by ozonation, ap-proximately $ 61.1\% $ or polioviruses were inactivated by ozone of 0.4 mg/l within 5 min. and $ 100\% $ were inactivated by ozone of 0.8 mg/l over 10 min.

스마트 폰의 등장과 모바일 인터넷을 제공함에 따라 휴대폰은 음성통신 수단이 아닌 웹을 통하여 서비스를 제공받는 도구 또는 각종 게임 및 응용 어플리케이션을 제공하는 놀이 수단으로도 발전하였고, 이로 인하여 사용량도 증가하였다. 사용량의 급증으로 인하여 모바일 광고에 대한 업계의 관심도 증가 하였지만, 한정적인 출력 화면에 의하여 광고 효과가 제한적일 수밖에 없다. 이를 보완하기 위해, 본 논문에서는 기업의 로고 광고의 효과를 극대화 할 수 있는 안드로이드 기반 로고 인식 증강 현실 시스템을 제안하였고, 이를 구현하여 실제 스마트 폰에 탑재한 후 다양한 성능 분석을 하였다. 실험결과, 그 가능성은 확인하였지만 현 하드웨어 성능상 실시간으로 지원하기에는 역부족임을 알 수 있었다. A mobile phone is becoming no longer a voice communication tool due to smartphones and mobile internet. Also, it now becomes a total entertainment device on which we can play game and get services by variety applications through the Web. As smartphones are getting more popular, their usages are also increased, which makes the interest of advertising industry in mobile advertisement increased but it is bound to be limited by the size of the screen. In this paper, we suggest an augmented reality logo system based on Android platform to maximize the effect of logo advertisement. After developing software and mounting it on a real smartphone, its performances are analyzed in various ways. The results show the possibility of its application to real world but it's not enough to provide real time service because of the low performance of hardware.

정은영,Jung, Eun-Young 한국융합학회 2021 한국융합학회논문지 Vol.12 No.7

본 연구는 일제강점기에 다양한 사건들 속에서 간호의 주체성을 지켜내기 위힌 노력의 과정들을 살펴봄으로써 미래의 간호 발전을 위해 현재 간호학이 갖추어야 할 방향을 제시하고자 시도되었다. 일제강점기 간호의 역사는 크게 3단계로 나누어볼 수 있다. 근대 간호의 태동기인 1910년부터 1919년에는 간호교육기관이 확장되고, 간호 관련 제도를 만들었다. 1920년부터 1937년은 근대 간호의 발전기로 간호의 영역 확대될 뿐 아니라 간호 관련 법령을 개정하고 2개의 간호협회를 조직 하였다. 근대 간호의 정체기인 1938년부터 1945년은 전쟁이라는 사회적 재난 속에서 전쟁인력 동원을 위한 간호사 양성 정책이 펼쳐지면서 또다른 변화를 경험하게 되었다. 이러한 역사적 변화 속에서 시대적 사건들에 대해 다양한 해석을 할 수 있지만 그 시대에 정립된 간호제도는 현재 간호의 초석이 되었다는 것은 공통된 해석이다 간호의 영역 확대와 지속적인 발전을 위해 과거부터 현재까지 사회적 다양한 사건들 속에서 변화되는 간호의 역할과 보급에 대한 지속적인 관심과 연구가 필요하다. This study attempted to present the direction that nursing should have for the future nursing development by looking at the process of trying to protect the subjectivity of nursing in various events during the Japanese colonial period. In the early days of modern nursing, from 1910 to 1919, nursing education institutions were expanded and nursing-related systems were created. From 1920 to 1937, as a development of modern nursing, not only expanded the field of nursing, but also revised nursing-related laws and organized two nursing associations. From 1939 to 1945, the stagnation period of modern nursing, amidst the social disaster of war, a training policy for mobilizing war personnel was unfolded, and another change was experienced. In order to expand the field of nursing and continue to develop it, continuous interest and research on the role and spread of nursing that change in various social events from the past to the present are needed.

Tracheal injury is a rare complication of endo-tracheal intubation. However in neonates, the rates of morbidity and mortality are high. Recommendations for treatment are based on the several reports of this injury and are individualized. Conservative management can be effective in some cases. We describe the case of a neonate who presented with subcutaneous emphysema after intubation in a neonatal intensive care unit. This patient suffered full VACTERL syndrome and had 1.7 mm diameter subglottic stenosis. Conservative management resulted in no further increase in subcutaneous emphysema and after 10 days the patient was stable.

The objective of this study was to investigate the effects of soy hydrolysate fractions on appetite suppression and ghrelin releasing. In a short-term experiment, the cumulative food intake and serum ghrelin level were decreased significantly (p<0.05) during a 4-hr period after the interperitoneal injection of soy hydrolysate fractions (0.5, 1 g/kg BW), following a 12-hr period of food deprivation. In a long-term experiment, food efficiency ratio (FER) was also reduced significantly (p<0.05), when soy hydrolysate fractions (0.5, 1% in drinking water) were given orally for 8 wks. Therefore, we found that soy hydrolysate fractions affected food intake through appetite and ghrelin releasing in short-term and long-term experiments. In conclusion, this study indicated that soy hydrolysate fractions would diminish the sensation of hunger by reducing the secretion of orexigenic factors such as ghrelin that send satiety signals to the brain, terminating food intake.

The laparoscopic splenectomy (LS) became popular over the last 10 years. The advantage of LS over open splenectomy (OS) includes short hospital stay, improved cosmesis, less development of postoperative intestinal ileus, and less analgesics required. The purpose of this study is to evaluate the outcome of LS at Asan Medical Center from January 1999 to January 2003. The records of 14 consequent children who underwent splenectomy were reviewed retrospectively. Patients characteristics, morbidity, mortality, operative time, blood loss, and hospital stay were analyzed., Seven patients age 5 to 15 years underwent LS under the indications: idiopathic thrombocytic purpura (ITP, n=3), hereditary spherocytosis (n=3), and myelodysplastic syndrome (n=l). Seven patients, age 7 to 16 years, underwent OS during the same period for ITP (n=7). Median operative time was 120 mInutes (80 to 170 mins.) in OS, and 270 minutes (110 to 480 mins,) in LS (p<0.05). Median length of hospital stay was 6 days (3 to 8) in OS, and 4 days (3 to 6) in LS (p>0.05). Median splenic length was 12.0cm (9.2 to 18.0) in OS, 14.0 cm (10.0 to 19.5) (p>0.05). Accessory spleens were identified in 3 of 7 LS and 1 of 7 OS cases. In the LS group, there was no conversion to open surgery. Two patients in LS required blood transfusion postoperatively. LS in children can be performed as effectively and safely as OS.

Controlled trials have shown that an external breast tissue expander can effectively enlarge the breast without surgery. According to 8 weeks, the authors critically evaluated her clinical experience with Beautiful-breast up (BB-UP) and attempted to identify factors associated with a successful outcome. The women used vibration and electrical muscle stimulation (EMS) system 1 hours a day. Breast volume measurements and standardized photographs of the breasts were obtained at the beginning of treatment and up to 8 weeks after treatment ended. Comparison among the methods was made using the three dimensional (3D) volume measurement of 23 women`s breast. The breast lateral length (p<0.001) and upper length (p<0.05) increased significantly pre-experiment compared to post-experiment, respectively. In conclusion, short-term breast volume enlargement without surgery is possible with an external tissue expander. The more it is used, the more the breasts grow. To avoid disappointments and drop-outs, women have to be well informed about the time and lifestyle commitment.
