Objective : Insomnia is the disorder of initiation or maintenance in sleeping that results in daytime sleepiness and dysfunction, and it arises from multiple psychological, physiological and environmental factors. A number of stroke patients suffer from insomnia are classified as sleep disorder patients with physical illness. In addition, insomnia may have profound deleterious effects on the natural course of stroke. We are to assess the effectiveness of intradermal acupucture on stroke combined with insomnia. Methods : We recruited hospitalized patients with insomnia after stroke. Then, the subjects were allocated into a treatment group and a control group by randomization. The treatment group received intradermal acupuncture therapy at He-7(神門), EH-6(內關) correctly. However in control group, intradermal acupuncture were just attached to He-7(神門), EH-6(內關) without insertion. Treatment over time at first day and second day a various indexes were repeatedly checked such as sleep latency, total sleep time, sleep quality, condition on awakening, ability of concentration, morning sleepiness, Insomnia Severity Index, and Athens Insomnia Scale. In the second analysis, we divided the treatment group into a response and a non-response group by their response to intradermal acupuncture. With the acupuncture treatment, accompanied symptoms were checked Results : Among thirty two subjects, two of them were dropped out: One complained the pain from needle insertion, and the other underwent the change of his herbal medication. At baseline investigation with the residual 30 subjects, the control and the treatment group were assessed to have an equal comparability. In the treatment group, sleep latency, total sleeping time, a number of awakenings, sleep quality and ability of concentration showed improvement significantly compared with the control group. The non-response Group showed symptoms such as nausea and halitosis, belching and acid regurgitation, abundant expectoration, while Responder Group showed palpitation, oppressed feelings in chest and sleep disorder. Conclusions: The result of this clinical study suggests that the intradermal acupuncture at He-7(神門), EH-6(內關) is one of the effective treatments for the insomnia after stroke.

정확한 복사 관측자료는 기후 및 날씨뿐만 아니라 해양과 건축 및 농 축산 분야 등 중요하게 활용된다. 특히 이어도와 같은 종합 해양과학기지는 주변 환경에 의한 복사 반사 효과를 최소화할 수 있기 때문에 이상적인 관측소로 평가되며 여기서 생산되는 자료는 복사관측의 기준 자료가 될 수 있다. 또한 BSRN (Baseline Surface Radiation Network) 등 세계복사관측그룹 가입을 위한 필수 장비들(전천과 직달 및 산란 일사계 등)을 갖추고 관측소 환경을 개선할 경우 전 세계적인 중요 관측소로 부각될 수 있는 여건을 갖추고 있다. 이어도 종합해양과학기지는 2004년 11월부터 일사계 관측을 수행해 왔고 이 연구에서는 2005년 1월 1일부터 2015년 12월 31일까지의 자료를 분석하였다. 이 연구 기간에 이어도의 일평균 일사량은 $-3.80W/m^2/year$로 감소하였고 그 이유는 자연적 원인 이외에 관측장비의 센서 반응도 감소 효과가 포함되어 있기 때문이다. 즉 이어도 종합해양과학기지의 경우 정밀한 복사 관측 자료를 생산하기 위해서는 관측소 환경 개선뿐만 아니라 관측장비 및 자료 보정이 요구된다. 그리고 한반도의 대기 청정도와 국민 건강을 크게 위협하고 있는 중국발 황사와 미세 먼지는 전 세계 과학자들의 중요 관심 대상이기 때문에 이어도뿐만 아니라 신안 가거초 및 옹진 소청초 종합해양과학기지 복사 관측자료를 통한 공동 대응 근거 마련이 필요하며 그에 따라 이들 복사관측소 환경 및 장비 개선 그리고 관측자료 정확성 향상 계획 수립이 시급하다. The radiation observation data will be used importantly in research field such as climatology, weather, architecture, agro-livestock and marine science. The Ieodo Ocean Research Station (IORS) is regarded as an ideal observatory because its location can minimize the solar radiation reflection from the surrounding background and also the data produced here can serve as a reference data for radiation observation. This station has the potential to emerge as a significant observatory and join a global radiation observation group such as the Baseline Surface Radiation Network (BSRN), if the surrounding of observatory is improved and be equipped with the essential radiation measuring instruments (pyaranometer and pyrheliometer). IORS has observed the solar radiation using a pyranometer since November 2004 and the data from January 1, 2005 to December 31, 2015 were analyzed in this study. During the period of this study, the daily mean solar radiation observed from IORS decreased to $-3.80W/m^2/year$ due to the variation of the sensor response in addition to the natural environment. Since the yellow sand and fine dust from China are of great interest to scientists around the world, it is necessary to establish a basis of global joint response through the radiation data obtained at the Ieodo as well as at Sinan Gageocho and Ongjin Socheongcho Ocean Research Station. So it is an urgent need to improve the observatory surrounding and the accuracy of the observed data.

본 연구는 불소함유 접착테잎의 법랑질 침식 예방효과를 평가하기 위해건강한 소의 치아를 절단하여 아크릴 주형에 매몰하고 정중선에 홈을 형성하여 대조면과 불소 제제를 도포할 실혐면으로 나누었다. 시편을 무작위로 18개씩 4군으로 나누었다. 1군은 APF gel를 도포하고, 2군은 불소 바니쉬를 도포하였으며, 3군과 4군은 5% NaF를 각각 첨가한 methyl cellulose와 poly vinyl alcohol 테잎을 부착하였다. 시편을 콜라에 5분, 증류수에 10분씩 6회 번갈아 처리하며 5일 동안 반복하였다. 시간 경과에 따라 표면미세경도를 측정하고 5일후 각 시편을 절단하여 침식병소의 깊이를 측정하여 다음과 같은 결과를 얻었다. 1. 표면미세경도 값은 5일째만 제외하고 2군, 3군, 4군의 실험면이 각각의 대조면에 비해 컸다 (p<0.05). 2군, 3군, 4군의 실험면 역시 5일째만 제외하고 1군의 실험면에 비해 표면미세경도가 컸다 (p<0.05). 3군과 4군 사이에는 표면미세 경도의 유의한 차이가 없었다(p>0.05). 1군의 실험면과 대조면은 표면미세경도의 유의차가 없었다(p>0.05). 2. 침식병소의 깊이는 2군, 3군, 4군의 실험면이 각각의 대조면에 비해 컸다(p<0.05). 2군, 3군, 4군의 실험면은 1군의 실험면에 비해 침식병소의 깊이가 얕았다 (p<0.05). 2군, 3군, 4군의 실험면 사이의 침식병소의 깊이는 유의차가 없었다(p>0.05). 상기 결과로 보아 새로 개발된 불소함유 접착테잎은 기존의 불소 바니쉬와 같은 법랑질 침식 예방효과가 분명하게 나타나, 법랑질 침식에 감수성이 높은 어린이 환자에게 임상적인 예방법으로서 활용할 수 있는 가능성이 높다고 사료된다. This study examined the effect of adhesive tape supplemented with sodium fluoride on the prevention of dental erosion in vitro. Sound bovine tooth samples were selected and divided randomly into the following 4 groups according to the material treatments: group 1, APF gel; group 2, fluoride varnish; and groups 3 and 4, fluoride tape supplemented with 5% NaF in either a methyl cellulose or poly vinyl acetate carrier, respectively. All specimens were submitted to alternate cycles of acid exposure in a cola beverage (pH 4.3) and artificial saliva for $6\;{\times}\;5\;min/day$ over a 5 day period. The micro-hardness was recorded each day and the lesion depth was measured after 5 days. The micro-hardness of the experimental sides of groups 2, 3 and 4 were significantly higher than that of their control sides and the experimental side of group 1 during the experimental period (p<0.05) except on the 5th day. The enamel surfaces of treatment groups 2, 3 and 4 showed significantly higher resistance to mineral loss in terms of the erosion depth (p<0.05) than group 1 and their control sides. There was no statistically significant difference among group 2, 3 and 4, indicating that the fluoride varnish and tapes produce similar results. Fluoride adhesive tapes are effective in reducing the progression of erosion and can be recommended for young patients who are more susceptible to dental erosion.

The process optimization of ozone concentration and half life time was investigated in ultra pure water and alkaline solutions for the wet cleaning of silicon wafer surface at room temperature. In the ultra pure water,. the maximum concentration (35 ppm) of ozone was measured at oxygen flow rate of 3 liters/min and ozone generator power over 60%. The half life time of ozone increased at lower power of ozone generator. Additive gases such as $N_2$ and $CO_2$ were added to increase the concentration and half life time of ozone. Although the maximum ozone concentration was higher with the addition of $N_2$ gas, a longer half life time was observed with the addition of $CO_2$. When $NH_4OH$ of 0.05 or 0.10 vol% was added in DI water, the pH of the solution was around 10. The addition of ozone resulted in the half life time less than 1 min. In order to maintain high pH and ozone concentration, ozone was continuously supplied in 0.05 vol% ammonia solutions. 3 ppm of ozone was dissolved in ammonia solutions. The static contact angle of silicon wafer surface became hydrophilic. The particle removal was possible alkaline ozone solutions. The organic contamination can be removed by ozonated ultra pure water and then alkaline solution containing ozone can remove the particles on silicon surface at room temperature.

휴대폰 및 카메라 산업의 급속한 발전에 따라 모든 전자 제품이 소형화, 고성능화, 다양화 추세에 따라 PCB도 고집적화, 다층화, 고사양화가 급속히 이루어지고 있다. 현재 계속해서 진화하고 발전하는 디지털 카메라 그 중에서도 DSLR카메라 이외에 소형, 경량화 하는 고객 요구로 부터 탄생한 미러리스 카메라와 하이브리드 디지털 카메라의 시장이 계속해서 증가하고 있다. 그에 고사양, 저전력, 고성능 부품에 따라 PCB설계 난이도가 점차 증가하고 설계 L/T이 오래 걸리고 있다. 본 논문에서는 디지털 카메라 개발기간 및 제조기간 축소에 적용되는 PCB설계 L/T 단축에 대한 방법을 제안한다. According to the rapid development of cell phone and camera industry, all of electronic products obtain small-size, high-performance and variety. Therefore, PCB also obtains high-integration, multi-layers and high-specification rapidly. Among the digital cameras which are continuously evolved and developed, the market of mirror-less camera and hybrid digital camera is continuously increased because of the customer's request for small-size and weight lightening, except for DSLR camera. Therefore, the difficulty of PCB design is gradually increased and design L/T is longer according to the high-specifications, low-current and high-performance components. This thesis suggests the method to reduce L/T for PCB design applied to the reduction of digital camera's developing period and manufacturing period.

Eight patients underwent tracheal resection and reconstruction for tracheostomy and postintubation injuries from 1971 to early 1981. The ages ranged from 12 years to 59 years. The patients had 7-cuff stenosis and one stomal lesion in whom intubated long. Four male and four female patients were treated. Cervical approach was used in one, cervicomediastinal in 3 and transthoracic in four. The longest length of resection extended to 4 cm in whom cervico-upper half mediastinal incision and neck flexion were applied. Techniques for obtaining tension-free anastomosis included cervical flexion or division of the inferior pulmonary ligament and mobilization of the right hilum. Concurrent tracheostomy was not needed in all. There was one death at the end of emergency operation from anesthetic accident. Granulations at the anastomosis line, necessitating bronchoscopy, were noted in two and the lesion did not recurred after removal. No restenosis or other complications occurred during long follow-up.

The effect of cardiopulmonary bypass procedures on the blood components were studied through the measurements of several serum enzymes, SGOT, SGPT, CPK and LDH with its isozymes in the patients who had surgery for their heart diseases. They wre 85 patients: 40 Males and 45 Females. Their ages ranged widely between one and fifty-six. They were divided into 5 groups: Group I.patent ductus arteriosus without extracorporeal circulation, Group II-atrial septal defect, Group III-ventricular septal defect, Group IV-tetralogy of Fallot, and Group V-valve replacement. Generally serum enzymes revealed the increased values after surgery and the tendency returning toward preoperative levels. With the high total serum LDH levels seen uniformly after operation which persisted long in patients with replaced valves, the changes of LDH-isozymes were further analyzed. The isozymes, especially LDI and LDs increased their activities postoperatively, and the other fractions varied little. And $LD_1$/$LD_2$ ratios also showed similar rises and falls while the elevated values lasted longer in the patients with cardiac valve replacement. The significant values of LDH-isozymes in predicting the hemolysis occuring after extracorporeal circulation and in following the patients whose valves were replaced have been further discussed with the special stress placed on the $LD_1$/$LD_2$ratios.
