Background : Recently the number of atopic dermatitis patients has increased, but the treatment of atopic dermatitis is not effective, and the recurrence rate of atopic dermatitis is high. Many patients are suffering from pruritus. A new standard treatment system is needed. Objective : This study investigated the effect of Oriental medicine program for atopic dermatitis patients during short term hospitalization. Method : 6 patients were admitted for short term hospitalization program. The program includes Acupuncture, herbal medicine, examination, education, cupping therapy, herbal dressing, exercise and etc. Everyday we evaluated the patients by Severity Scoring Atopic Dermatitis(SCORAD) index and took the photos of lesions, and the patients evaluated themselves by atopic dermatitis diary which consists of emotion, pruritus, sleep loss. Results : Admission duration was 7 to 14 days. The SCORAD scores of them were decreased. Most symptoms of 6 patients were improved. Especially herbal dressing was effective for severe oozing. Subjective scores of atopic dermatitis diary were reduced. Conclusion : We expect that the short term hospitalization program could be helpful for uncontrollable atopic dermatitis patients.

Thin client computing trades local processing for network bandwidth consumption by offloading application logic to remote servers. User input and display updates are exchanged between client and server through a thin client protocol. On wireless devices, the thin client protocol traffic can lead to a significantly higher power consumption of the radio interface. In this article, a cross-layer framework is presented that transitions the wireless network interface card (WNIC) to the energy-conserving sleep mode when no traffic from the server is expected. The approach is validated for different wireless channel conditions, such as path loss and available bandwidth, as well as for different network roundtrip time values. Using this cross-layer algorithm for sample scenario with a remote text editor, and through experiments based on actual user traces, a reduction of the WNIC energy consumption of up to 36.82% is obtained, without degrading the application's reactivity.

찰스 린드버그는 1927년 뉴욕에서 출발한 후 약 20시간 동안 대서양 횡단 비행 중 피로로 인해 잠든 동안 항공기가 통제되지 않는 상황을 경험하였다. NTSB(National Transportation Safety Board) 보고서에 따르면 매년 약 40건의 준사고가 피로와 관련되어 있는 것을 알 수 있다. 수면 손실은 알코올과 비슷한 효과를 유발할 수 있으며, NTSB에서 꾸준히 조사 중에 있는 부분이기도 하다. 피로는 특히 이륙 및 착륙 시 위협 및 오류 관리에 영향을 줄 수 있다. 본 연구에서는, NTSB가 일반적인 요인인 피로를 분석한 주요사고의 위협과 오류를 식별하고 피로의 심각성을 이해하고자 한다.

Purpose. This intra-patient retrospective study of up to 10 years evaluated the clinical success and risk factors of 6- and 8-mm long implants and their respective prostheses. Materials and Methods. The sample consisted of patients treated at a Military Polyclinic dental service, who received both 6- and 8-mm long tissue level implants in the posterior region of the same arch. Data were collected from the dental charts, clinical and radiographic exams, self-report of sleep bruxism, measurement of maximum occlusal force, and clinical crown-to-implant (C/I) ratio. Data were analyzed by descriptive and inferential statistics with univariate and hierarchical multivariate models, at the 0.05 significance level. Results. The 30 patients (27 women) had 85 implants and 83 prostheses. Two implants were lost before prosthesis installation (implant survival: 97.6%). Ten events of prosthetic complication (screw tightening loss) occurred in five patients (success rate: 87.9%) in a single moment. Only the variable C/I ratio had a significant effect for repairable prosthesis complication (P<.05). Conclusion. The results suggest that 6- and 8-mm long implants have similar long-term clinical success for implants and prostheses.

연구배경 : 구개수구개인두성형술(uvulopalatopharyngoplasty : UPPP) 은 폐쇄성 수면 무호흡 증후군 환자에서 가장 보편적으로 시행되고 있는 외과적 치료법이지만 치료 효과에 대하여는 논란의 여지가 많으며, 국내 연구 자료는 매우 부족한 실정이다. 방 법 : UPPP를 시행한 폐쇄성 수면 무호흡 증후군 환자들 중에서 일차 추적 수면다원검사가 가능했던 26명을 대상으로 단기 치료 효과를 관찰하였다. 치료 효과는 두가지 기준에 의해 평가하였다. 첫 번째는 일반적인 평가 기준으로써, UPPP 시행으로 무호흡지수(apnea index : AI) 혹은 무호흡-저호흡지수(apnea-hypopnea index : AHI)가 50% 이상 감소한 경우 혹은 UPPP 시행 후의 AI가 10 미만이거나 AHI가 20 미만인 환자들을 효과가 있는 경우 즉 반응군으로 정의하였고, 두 번째는 저자들이 설정한 평가 기준으로써, UPPP 시행 전의 AI 혹은 AHI와 관계없이 UPPP 시행 후의 AI가 5 미만이거나 AHI가 10 미만인 환자들을 단기적으로 폐쇄성 수면 무호흡 증후군이 치유된 경우 즉 치유군으로 간주하였다. 비만도, AI 및 AHI와 UPPP 시행에 의한 AI 및 AHI 감소율과의 관련성을 관찰하였고, 수면 구조를 비교함으로써 UPPP의 시행으로 수면의 질이 개선될 수 있는지 여부를 분석하였다. UPPP 시행 후 10일 이내에 발생한 문제점을 조기 합병증으로 정의 하였고, 10일 이후에 발생한 부작용은 후기 합병증으로 분류하였다. 결 과 : 26명의 환자 중에서 반웅군은 18명(69.2%) 이었고, 10명(38.5%)은 단기적으로 폐쇄성 수면 무호흡 증후군이 치유된 소견을 보였으며 5명(19.2%)은 UPPP 시행 후에 AI 혹은 AHI가 오히려 증가되었다. UPPP 시행 전의 비만도는 AI 감소용 및 AHI 감소율과 상호 관련성이 없었고, UPPP 시행 전의 AI는 AI 감소율과 상관관계가 없었으며, AHI 역시 AHI 감소율과 관련성이 없었다. 전체 대상 환자, 반웅군 및 비반웅군, 치유군 및 비치유군 각각에서 UPPP 시행 전후 수면 구조의 유의한 변화는 없었다. UPPP 시행에 따른 조기 합병증으로 비교적 심한 수술 부위의 통증, 음식물의 비역류, 기침이나 호흡곤란 등의 호흡기 증상, 수술 부위의 출혈, 연하곤란, 귀의 통증 혹은 봉합 부위 파열 등이 전체 환자(100%)에서 발생하였고, 후기 합병증으로 인후의 건조감, 비역류, 음성의 변화, 연하곤란, 인후의 이물감 혹은 미각변화 등이 22명(84.6%)의 환자에서 관찰되었으나, 합병증은 모두 경미한 것이었다. 결 론 : 폐쇄성 수면 무호흡 증후군 환자의 약 70%가 UPPP의 시행으로 호전을 보이지만, 치료 효과가 충분한 경우는 약 40%에 불과하였다. 치료 효과를 높이기 위해서는 엄격한 기준에 의한 적응증의 결정과 더불어 적절한 수술 방법이 필요할 것으로 생각한다.

1. Objectives: This clinical study was conducted to understand the differences between Sasang constitutional types and to identify the physical symptoms presentation specific to each Sasang constitutional type. 2. Methods: In this descriptive study, 2,629 subjects (1,061 Taeeum-type, 683 Soeum-type, 885 Soyang-type) were surveyed between Nov 1, 2007 and Jul 31, 2010. The subjective symptoms experienced by the subjects were collected using a Physical Symptoms questionnaire, and the subjects were interviewed by Sasang specialists who determined the subjects' constitutional type. The data (in crude number and percentage) was analyzed on the general characteristics, Sasang constitutional type, and physical symptoms using the SPSS 17.0 software. The symptomatic presentation in men and women were analyzed on Sasang constitutional distribution using the chi-square test. 3. Results: 1) The physical symptoms specific to each Sasang constitutional type were as follows: 'frequent aphthous lesions in the oral cavity', 'lingering fatigue after sleep', 'headache', 'common cold symptoms presenting as loss of appetite or indigestion', and 'physical deterioration presenting as problems with digestion' in the Soeum type; 'physical deterioration presenting as problems in perspiration' and 'swelling and puffiness' in the Taeeum type; and 'excessive forgetfulness' in the Soyang type. 2) The physical symptoms specific to each Sasang constitutional type in men were as follows: 'Unilateral or bilateral headaches, 'frequent aphthous lesions in the oral cavity', 'common cold symptoms presenting as rhinorrhea or nasal congestion', 'common cold symptoms presenting as loss of appetite or indigestion', and 'physical deterioration presenting as problems with digestion' in the Soeum type; and 'swelling and puffiness' in the Taeeum type. 3) The physical symptoms specific to each Sasang constitutional type in women were as follows: 'common cold symptoms presenting as headaches', 'common cold symptoms presenting as loss of appetite or indigestion', 'physical deterioration presenting as problems with digestion' in the Soeum type; and 'pain in knees', 'redness of eyes', 'dryness of mouth', 'common cold symptoms presenting as coughing', 'physical deterioration presenting as problems in perspiration', 'swelling and puffiness' in the Taeeum type. 4. Conclusions: This study demonstrates that physical symptoms present in constitutional type-specific patterns. Understanding of the personal Sasang constitutional type and systematic, personalized healthcare based on constitutional typology is anticipated to contribute to improved health management strategy.

Leukemia is a blood disease that occurs in the abnormal process of leukocyte maturation. Its main medical treatment is chemical therapy and bone medical transplant. But its treatments give rise to ill effects and sequela. At present, the cause of leukemia is not fully understood. But oriental concept of curing leukemia is the holistic thinking that emphasizes the unity, wholeness, and the relationship between the human organs, including western medical concept of blood cause. So it is estimated that holistic medical treatment in oriental medicine could present new medical way of curing leukemia. I read over the diary on struggles against leukemia, survey on the leukemia patients, and, medical charts in the oriental clinics that treated in the holistic way, and I interviewed the leukemia patients. With these materials, I classified the early main attacking symptoms according to the chief complaints of one hundred leukemia patients. With these results collected, I present new alternative treatment by oriental medical diagnosis. The chief early complaints that leukemia patients give are fatigue, enervation, cold, contusion, fever, high fever, sweating at sleep, myalgia, arthralgia, and dizziness, in order of main symptoms. Fatigue occurs mainly by spleen and stomach weakness and marrow shortage. So it is estimated that It is important to treat the spleen that is responsible for supplementing the marrow. Because the leukemia patients have anemia and hemorrhage, to treat the spleen is important for hematopoiesis and controlling blood. In case of cold, it penetrates into the body when the body is weak. So its treatment is to increase body's health. But the cause of fever is difficult to classify into outer cause and inner cause. But in case of children under 14 years old, fever is the main sypmptom. I think this is because children have the body with pure vital energy. Hemorrhage is thought to be the result of yin-lack and heat-miasma of spleen and stomach channels. Contusion occurs from the qi-weakness and the not-controlling-blood. Sweating at sleep is from the yin-weakness. It is found with all weak symptoms. Dizziness is from the yin-blood impairment. Weight-loss is from the marrow shortage. Myalgia and arthralgia is mainly from inner weakness, not outer maisma. Most leukemia patients have the idea that holistic treatment of leukemia could be of assistance and give help to the low immunity. So it is expected that holistic medical treatment could contribute to knowing the cause and treatment of leukemia, and give people reliability on oriental medical treatment, through the profound diagnosis of leukemia.

구개인두성형술은 만성 코골음 및 폐쇄성 수면 무호흡증의 치료를 위해 널리 이용되고 있는 수술이며 수술 직후의 치료 효과 및 합병증에 대한 연구는 많이 이루어져 있으나 5년 이상의 장기 추적 관찰에 관한 연구는 드물게 보고 되고 있다. 이에 저자들은 1985년부터 1987년까지 구개인두성형술을 시행한 총 37명의 환자중 추적관찰이 가능했던 25명의 환자(남:18명, 여:7명)를 대상으로 수술전, 수술후 8주 및 수술후 5년이 지난 환자의 주관적 증상을 비교 평가 하였으며 중상의 변화와 함께 체중의 증감도 같이 조사하여 다음과 같은 결과를 얻었다. (1) 수술후 5년된 25명의 환자에서 코골음은 10명(40%)에서 완전히 사라졌고 정도의 차이(Grade 1 - 3)는 있지만 3명을 제외한 나머지 모두에서 호전을 보였다. (2) 수술전 AI>20이었던 15명의 환자에서 발견된 수면 무호흡증은 추적 관찰용 수면 다원 검사상 13명의 환자에서 Grade 0 - 1 (Oxygen saturation 86%)로의 호전을 보였고 수술후 5년이 지난뒤에도 증상의 변화 및 체중 변화는 없었다. (3) 수술 5년후에도 문제가 되는 합병증으로는 물을 급히 마실 때에만 코끝에 물방울이 비치는 정도의 구개인두부전 3례, 인두 비대칭 1례, 인두 건조감이 5례에서 관찰되었다. 그외 비인두 협착, 미각 상실, 및 호흡 순환계의 장애 둥 심각한 합병증은 발견되지 않았다.

The purpose of this study were to investigate the bed climate and the physiological responses in sleep on the traditional Korean floor heating system called Ondol. Ondol has been the most widely used heating system in Korea, yet there has been a no systematic studies examined its environmental effects on human body. Experimental room was constructed to match the typical thermal environment of Ondol. (floor surface temperature; $32\~33^{\circ}C$, air temperature; $22.5{\pm}1.0^{\circ}C$, relative humidity; $64.0{\pm}4.0\%$RH, air velocity; 0.25 m/sec.) Three different combinations of bedclothes were chosen for the experiment based on the study results showing that they were the most widely used types in Korea. Type 1 was the combination of a cotton-padded mattress with a cotton-padded Korean style blanket. Type 2 was a cotton-padded mattress with a cotton-guilted Korean style blanket. Type 3 was a cotton-padded matless with a polyacryl blanket. Thermal resistance of each of these combina-tions in the bedclothes was measured using thermal manikin. Two adult female was chosen for the seven hour sleeping experiment which was known to be the average sleeping hours of Korean adult female. The bed climate was measured with the temperature under the mattress, the surface temper-ature of the mattress, and the air temperature and the relative humidity of the space between the mattress and blanket. The skin temperature, rectal temperature of the subjects and the bed climate were measured eight times, one hour before the experiment and every hour during the experiment. The weight loss and the subjective sensation were measured for the each subjects before and after the experiment. The procedure was repeated twice with two subjects and three types of bedclothes, yielding twelve combinations of results. The results were as follows; 1. With the surface temperature of $32\~33^{\circ}C$ of Ondol, air temperature was $22.5{\pm}1.0^{\circ}C$ with $64.0{\pm}4.0\%$ RH. The bed climates were $39.2{\pm}40.8^{\circ}C$ under the mattress, $35.3\~36.2^{\circ}C$ on the mattress, and $26.9\~32.0^{\circ}C$ with $56.0\~71.3\%$ RH between the mattress and the blanket. 2. Mean skim temperature during sleep was 34.2"C with local skin temperature of $34.0\~35.5^{\circ}C$. The skin temperatures of abdomen, thigh, foot were higher than the other parts of the body. 3. The skin temperature of chest, thigh, leg and back varied significantly according to the combinations of bedclothes. With the cotton-padded blanket, the skin temperature was the highest, while with the cotton-guilted blanket showed lowest. 4. Examining the relationship between the mean skin temperature and the local skin temper-ature, the chest temperature showed the highest correlation with the former. Therefore, the chest temperature can be recommended to represent the skin temperature in measuring the bed climate. 5. The subjective bed climates were $39.0\~40.4^{\circ}C$ under the mattress, $35.2\~35.9^{\circ}C$ on the mattress, $29.8\~31.6^{\circ}C$ with $56.8\~68.4\%$ RH between the mattress and blanket. In sum, from this experiment we not only obtained the reliable value of bed climates on Ondol, but also showed that the bed climates and the physiological responses were affected differently according to the materials of bed clothes.

본 연구는 방사선 치료 중인 암환자의 주관적 행복감을 향상시키기 위한 서비스를 탐색하기 위한 것이다. 백 한 명의 방사선 치료중인 암환자를 대상으로 설문조사하여 주관적 행복감에 영향을 줄 수 있는 자기의식과 증상 불편감을 파악하여, SPSS 20.0 프로그램을 이용하여 독립표본검정, 일원분산분석, 피어슨 상관분석을 시행하였다. 방사선 치료중인 암환자의 불편감은 피로감, 외모변화, 현기증, 식욕저하, 수면장애의 순으로 높게 나타났으며, 암환자의 주관적 행복감은 증상불편감이 낮을수록, 그리고 개인의 내면적인 의식이 높을수록 향상됨을 나타냈다. 따라서 방사선 치료기간 동안 주관적 행복감을 향상시키기 위해서는 증상불편감은 감소시키고, 개인의 의식수준을 향상시킬 수 있는 신체적 심리적 정서적 측면을 고려한 통합적 서비스가 필요하다. 이를 위해서는 기존의 서비스 프로그램의 보완과 환자의 편의를 고려한 치료병원과 지역암센터나 보건기관을 연계할 수 있는 시스템이 준비되어야 할 것이다.
