N/A Background: Clinical syndrome of leptospirosis in Korea which accompanied by hemoptysis, pulmonary hemorrhage, respiratory failure was quite different from that of typical Weil's disease. The death rate in the early stage of disease has relationship with chest X-ray findings and acid-base disturbances resulted from hypoxia and asphyxia. We've come to consider chest X-ray findings and arterial blood gas findings as factors influencing the prognosis of the disease. Methods: Forty one cases of leptospirosis diagnosed by acute febrille illness symptoms and serologic tests were graded for chest X-ray findings and grouped according to acid-base abnormalities. Retrospectively, we attempted to correlate the acid- base disturbances and chest X-ray findings with morbidity and mortality of the disease. Results: The result were as follows. 1) Abnormal chest X-ray findings were observed in 30 cases(73%). Mortalities according to the chest X-ray findings were 0(0%), 2(17%), 3(0%), 4(0%), 5(33%), 6(50%) and chest X-ray findings influenced the mortality with statistical significance(p<0.05). 2) Acid-base abnormalities were observed in 39 cases(95%) and the types were divided to six groups . Respiratory alkalosis was the most common acid-base disturbance(44%). Five cases were died. Two of five were respiratory alkalosis, two cases were mixed respiratory metabolic acidosis and another case was mixed respiratory-metabolic alkalosis. As shown, acid-base abnormality influenced the mortality and mixed acid-base disturbances were showed high mortality with statistical significance (p<0.05). 3) Total mortality was 12%(five of forty-one). The chest X-ray score, morbidity, pH, pCO2, pO2, and HCO3 were 5.0±0.8, 3.4±1,3, 7.16±0.17, 32.5±1.1, 43.3±13.4 and 17.6±3.1 in died group, 2.4±0.4, 12.7±1.0, 7.46±0.01, 48.8±13.4, 65.4±3.7 and 23.4±0.9 in recovery group, respectively. There was difference between two groups with statistical significance. Conclusion: In this study, we concluded that chest X-ray findings and acid-base abnormalities influenced the mortality of leptospirosis. The factors above mentioned make us consider chest X-ray and blood gas analysis are essential to the patient hospitalized for the suspicion of leptospirosis. Especially, these factors pointed out the patient having chest X-ray abnormalities and mixed acid-base disturbances needed intensive care in the early stage of leptospirosis.

본 연구는 소비사회 컨텍스트 아래 에로티시즘 디자인의 속성을 분석함으로써 대중소비 사회의 일상적인 삶을 통해 현 시대의 에로티시즘 디자인의 위치와 역할을 가늠해보고 그 가치를 재조명하는 것을 목적으로 한다. 에로티시즘에 대한 일반적 고찰을 토대로 에로티시즘과 디자인의 연계성, 그 역사적 변화 추이를 살펴보고, 이어 에로티시즘 디자인의 속성을 유희성, 관능성, 일탈성, 이상성의 4가지로 분류·분석하였다. 에로티시즘 디자인은 단순한 생산의 메커니즘에 의한 것이 아니라, 사물과 대중의 소비관계 이외에 문화적, 심리적, 상징적인 상호작용에 의한 것임을 파악할 수 있다. 에로티시즘 디자인은 소비욕구 충족의 메커니즘인 동시에, 인간의 욕구와 그에 대한 태도를 포함한 의지와 의식을 표명하는 하나의 기호(sign)이며, 단순한 상업적 선정성을 목적으로 하기보다는 사회를 살피고 진단하고 증언하는 폭넓은 도구의 역할을 하고 있다. 이는 소비수단의 핵심으로 여겨졌던 에로티시즘에 대한 해석을 새롭게 해야 할 필요성을 갖는 것이며, 나아가 에로티시즘 디자인의 가치를 밝히고 표현의 올바른 방향성을 제시해야 함을 시사한다. The purpose of this review is analysis of attributes of eroticism design under consumption society context, and finding the position and the role of eroticism design in popular consumption society through normal daily basis life. Also highlighting its value in the society. Through basic perception of eroticism, its attributes will be analyzed in four different categories - 1) playfulness, 2) voluptuousness, 3) deviation, 4) idealistic & utopian - and a prime example for each categories will be displayed to demonstrate in more detail with the current status of eroticism design. Through this review eroticism design is not simply result of mechanism of production, but besides the relationship between objects and popular consumption, it could be understood as the mutual effect of cultural, psychological, and symbolical combination. The function of designed object goes beyond the functionality area by playing a role of psychological sign based on popular desire, also as a licual language representing nonmaterial concept related to sexual instinct through design process. In other words, eroticism design is the recof dy of human sensitivity, where the human instinct is suppressed in the process through materialism, and coincides with all sorts of hidden inner desires. That is, the eroticism design satisfies the consumption desire and reliance including behavior and consciousness. Also its purpose is not a simple selection but it is used as a tool to testify the examination and diagnosis of the society. This means that the core perception of eroticism being a consumption method has to be changed, and furthermore the value of the eroticism design has to be revealed and guidance for right expression has to be presented.heowef d, the eroticism design disposition is not fixed yet.heistorically eroticism characteristic evolved depending on the period in the society and it will continuously evolve.reonsequently, the attributes of eroticism design and expression will never be fixed. Hence, after current research there will be additional research requirement of the new evolution of the characteristics and attributes of eroticism design in the future society in various cultures.

최근 AR, VR 및 스마트 디바이스 기술의 발전에 따라 피트니스 산업에서도 비대면 환경을 기반으로 한 서비스 수요가 증가하고 있다. 비대면 온라인 홈트레이닝 서비스는 기존의 오프라인 서비스에 비해 시간과 장소의 제약이 없다는 장점이 있으나 운동 기구의 부재 및 사용자의 정확한 운동 자세 유지여부, 운동량의 측정이 어려운 단점이 존재한다. 본 연구에서는 이러한 단점을 보완할 수 있는 표준 운동 프로그램을 개발하고 딥러닝 기반 신체 자세 추정 영상처리를 통하여 새로운 비대면 홈트레이닝 어플리케이션 알고리즘을 제안한다. 본 연구의 알고리즘 기반 어플리케이션을 활용한다면 표준 운동 프로그램 영상의 트레이너를 사용자가 직접 보고 따라하면서 사용자 스스로 자세를 교정하며 정확한 운동이 가능하다. 나아가 본 연구의 알고리즘을 용도에 맞게 커스터마이징 한다면 공연, 영화, 동아리 활동, 컨퍼런스 분야로의 적용도 가능할 것이다. Recently, with the development of AR, VR, and smart device technologies, the demand for services based on non-face-to-face environments is also increasing in the fitness industry. The non-face-to-face online home training service has the advantage of not being limited by time and place compared to the existing offline service. However, there are disadvantages including the absence of exercise equipment, difficulty in measuring the amount of exercise and chekcing whether the user maintains an accurate exercise posture or not. In this study, we develop a standard exercise program that can compensate for these shortcomings and propose a new non-face-to-face home training application by using a deep learning-based body posture estimation image processing algorithm. This application allows the user to directly watch and follow the trainer of the standard exercise program video, correct the user's own posture, and perform an accurate exercise. Furthermore, if the results of this study are customized according to their purpose, it will be possible to apply them to performances, films, club activities, and conferences

Degrees of hesitancy of cancer-patient on pain-management between two groups showed significant difference. Experimental-group changed from 2.33 to 1.35 point and control-group from 2.77 to 2.52 point(p=.000). Conclusion: Above findings showed that pain-management-education reduces the concern and hesitancy on pain-management in out-patient of terminal gastric cancer. We conclude that the pain-management-education in this study was identified the effective nursing program.

람블 편모충(Giardiasis) 감염에 의해 발현된 반응성 관절염(Reactive arthritis)

김태환,김종표,정성수,유대현,김성윤,이인홍,손영우,전용철,전재범,배상철,정자현 대한내과학회 2001 대한내과학회지 Vol.61 No.1

Giardia lamblia, a gastrointestinal protozoan, is one of the most common disease-causing parasites in the world. Giardiasis is primarily encountered in areas with poor sanitation, but it is also seen in more developed countries. A possible sequela of Giardia infections of the bowel is reactive arthritis or synovitis. Few reports of synovitis secondary to giardiasis exist in the literature. Arthropathy secondary to giardiasis is uncommon, but may be underdiagnosed. We present a 23 year-old woman who had polyarthritis after Giardia lamblia infestation. The synovitis subsided with treatment of the giardiasis with metronidazole. The diagnosis of Giardia synovitis should be suspected by the presence of Giardia cysts in the stool. Although uncommon, giardiasis can cause severe synovitis that may be confused with a septic joint. (Korean J Med 61:82-85, 2001)
