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.

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.

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.

이상호,김영길,Lee, Sang-Ho,Kim, Young-Gil 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.6

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.

이상호,곽정식,Lee, Sang-Ho,Kwak, Jyung-Sik 대한수사과학회 2007 대한수사과학회지 Vol.2 No.2

2001년부터 2005년까지 5년 동안 우리나라에서 발생한 강도사건은 모두 29,892 건으로 연 평균 약 5,978 건이 발생하였는데, 그 분석결과를 요약하면 다음과 같다. 수법은 침입강도가 8,605 건(28.8%)으로 가장 많았고, 침입구는 출입문이 4,031 건(64.3%)으로 가장 많았으며, 침입 방법은 문단속이 없는 출입문이나 창문을 통하여 침입한 것이 2,462 건(28.6%)으로 가장 많았고, 발생시간은 심야시간대 (00:00~04:00사이)가 가장 많았으며, 요일별로 보면 수요일이 5,652건으로, 일요일(2,988건)의 약 2 배가량 많이 발생한 것으로 나타났다. 강도범죄로 인해 신체적 피해를 입은 피해자는 사망 260 명, 상해 10,610 명으로 나타났으며, 발생장소는 노상(路上)이 10,183건(34%)으로 가장 많았고, 그 다음이 주거지로서 7,527 건(약25%)이 발생한 것으로 나타났다. 공범관계는 단독범이 15,012 명(56.1%)으로 가장 많았고, 범행시 범행도구는 소지하지 않음이 15,631건(58.4%)으로 가장 많았으나, 소지한 범행도구 중에는 칼이 6,498 건(24.3%)으로 가장 많았다. 2001년부터 2006년까지 6년 동안 대구지역에서 발생한 강도범죄는 모두 1,506 건으로 연평균 251 건이었으며, 이중 침입강도 사건은 515 건(34.2%)으로 연평 균 약 86 건이 발생하였는데, 발생시간은 역시 심야시간대(00:00~04:00사이)에서 가장 많이 발생(194 건, 37.7%)하였고, 침입 장소는 주거지(259 건, 50.3%)가 가장 많았으며, 침입구는 출입문(87 건, 33.6%)이 가장 많았고, 침입방법은 문단속이 없는 출입문이나 창문으로 침입한 것이(65 건, 25.1%) 가장 많은 것으로 나타났다. 그 외에 택배원 등 방문자로 가장하거나 피해자를 뒤따라 침입하는 수법도 26 건(10%)이 발생한 것으로 나타났다. 이러한 강도범죄 예방을 위해서는 국가적, 사회적 대책은 물론, 개인의 자위 방범활동도 상당히 중요한 부분을 차지한다는 것을 알 수 있었는데, 특히, 침입강도 범죄자가 시정되지 않은 출입문이나 창문을 통하여 가장 많이 침입한다는 분석결과를 볼 때 범죄예방에 대한 인식이나 노력이 많이 부족하다는 것을 알 수 있었다. 범죄예방을 위한 가장 기본적인 방법 중의 하나가 문단속이라는 사실을 모르는 사람이 없을 것임에도, 이러한 기본적인 방법조차 실행하지 않아 강도범죄의 피해자가 된다는 것이 그것을 뜻한다. 따라서 본 연구에서 나타난 강도범죄의 실태를 참고하여 범죄예방에 대한 관심을 가짐으로써 강도범죄의 피해자가 한 사람이라도 줄어 들었으면 한다. 최근 과학수사에 대한 사회전반의 인식향상에 따라 경찰기관에서도 범죄분석요원, 피해자심리상담요원, 검시관 등을 특별채용하여 각 종 범죄분석 등 과학수사의 발전 기반이 마련되고 있다. 이를 토대로 범죄예방을 위한 심도있는 연구가 더욱 활발하게 이루어지기를 기대한다. During the period from 2001 to 2005, 29,892 burglaries took place in Korea with the approximate average annual number - 5,978 cases. This study was conducted to analyze the reported burglaries and the result was summarized as follows. There were 8,605 residential invasion burglaries (28.8%) as the most frequent characteristic pattern. The exit was used as the most frequent invasion route for 4,031 invasion burglaries (64.3%), and an unlocked exit door or window was used as the most frequent invasion method for 2,462 invasion burglaries (28.6%). The hours just after midnight (between 00:00 and 04:00) were the most frequent time for invasion burglary to occur. Also, 5,652 burglaries occurred on Wednesday which was twice higher than on Sunday (2,988 burglaries). It was shown that the number of persons injured during burglaries were 260 deaths and 10,610 injuries. The places of the highest occurrence were the street with 10,183 burglaries (34%) and then residential place with 7,527 burglaries (approximately 25%). One-man burglary was the highest complicity: 15,012 offenders (56.1%). The knife was used as the most frequent instrument for 6,498 burglaries (24,3%) what is rare, while no criminal tool or instrument was used for 15,631 burglaries (58.4). During the period from 2001 to 2006, 1,506 burglaries occurred in Daegu and the average annual number was 251 burglaries. Among those,515 residential invasion burglaries (34.2%) took place and the average annual number was approximately 86 cases. The hours just after midnight (between 00:00 and 04:00) were the most frequent time for invasion burglary to occur (194 cases, 37.7%), the place of the highest invasion occurrence was the residential place (259 cases, 50.3%), and the exit was used as the most frequent invasion route (87 cases, 37.7%). An unlocked exit door or window was the most frequent invasion method (65 cases, 25.1%). In addition, pretending to be a delivery man, visitor or following the victim methods were used for 26 burglaries (10%). It is apparent that personal preventive measures against crimes, as well as governmental and social measures, play an important role in preventing burglaries. In particular, based on the analyzed result that an unlocked window or exit door was most frequently used for reported burglaries, it seems that there is a lack of understanding of crime prevention while little effort has been made to prevent crimes. Although everyone knows that locking a door is one of the basic measures to prevent crimes, many people tend to pay little attention to lock a door properly so burglary takes place. This study, therefore, is intended to encourage people to pay more careful attention to crime prevention, in order to help reduce the probability of burglary. With the recent improvement in social understanding of scientific crime investigation, a wide variety of police professions, including crime analysts, crime victim police counselors and coroners, have been prepared to develop the scientific crime investigation and crime analysis. In addition, it is hoped that further this study will contribute to encourage studies on crime prevention to be carried out in the future.

Auxins are essential in plant growth and development. The auxin-stimulated elongation of plant cells has been explained by the "acid-growth theory", which was proposed forty years ago. According to this theory, the auxin activates plasma membrane $H^+-ATPase$ to induce proton extrusion into the apoplast, promoting cell expansion through the activation of cell wall-loosening proteins such as expansins. Even though accepted as the classical theory of auxin-induced cell growth for decades, the major signaling components comprising this model were unknown, until publication of recent reports. The major gap in the acid growth theory is the signaling mechanism by which auxin activates the plasma membrane $H^+-ATPase$. Recent genetic, molecular, and biochemical approaches reveal that several auxin-related molecules, such as TIR1/AFB AUX/IAA coreceptors and SMALL AUXIN UP RNA (SAUR), serve as important components of the acid-growth model, phosphorylating and subsequently activating the plasma membrane $H^+-ATPase$. These researches reestablish the four-decade-old theory by providing us the detailed signaling mechanism of auxininduced cell growth. In this review, we discuss the recent research progress in auxin-induced cell elongation, and a set of possible future works based on the reestablished acid-growth model.
