This study was aimed to get the course which is caused by Neuropsychiatric symptoms in Sang-Han. Therefore this study is based on 『Euhak-Ipmun. Sang-Han』(『醫學入門.傷寒』) classfied mainly by symptoms. The results were summerized as follows: 1. Neuropsychiatric symptoms in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』) are explained as Pal-Gang(八綱), which shows those are settled down to a systematic oriental medical theory. 2. Pal-Bup (八法) used in the cure of symptomatische psychose in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』), which is intended to boost the effect of cure, choosing the respondent cure method about various causes. 3. Pal-Gang(八綱) and Pal-Bup(八法) in『Euhak-Ipmun. Sang-Han』(『醫學入門·傷寒』) are improved by Lee-Chun(李 ) who added Jang-gi(張機)'s Sang Han theory and new medical thought in the ages of Geum. Won. 4. Lee-Chun(李 ) believed that Neuropsychiatric symptoms which appeared in Sang Hang is caused by the "Unbalance(不平)". So he wanted to reach harmony of "Jeong(精), QI(氣), Shin(神), Hyul(血)" after improving the status of "Unbalance(『不平』)" toward the status of "Balance(平)".

1993년부터 2015년까지 관측된 제주도 지하수 장기모니터링 관측정(N = 4,835)에서 수집된 지하수 수질자료(N = 21,568)를 기반으로 질산성질소의 시공간적 변동 특성을 평가하였다. 제주도 지하수의 질산성질소 농도의 중앙값은 2.5 mg/L로서 다른 국가나 대륙의 조사 결과에 비해 다소 높거나 유사한 것으로 나타났다. 또한 지하수 용도, 행정구역 및 고도 별로 유의한 차이를 보였다. 특히, 산간 지역에 비해 저지대 해안가에 위치한 농업 및 주거지역에서 농도가 높음을 확인하였다. Mann-Kendall 및 Sen’s slope 분석을 활용한 질산성질소 농도의 추세 분석 결과, 하류 저지 대에 비해 중산간지역에서의 질산성질소 농도 증가 경향이 뚜렷하였다. 제주도 내 토지 피복의 시계열 변화 특성과 결부 지어 보면, 중산간지역의 오염 증가 추세는 농업지역의 확장 등 인위적 활동 증가에 기인한 결과로 판단된다. 반면,기지정된 지하수자원특별관리구역에서는 전반적으로 질산성질소 농도의 감소 경향이 나타났는데, 이는 지하수 관리 측면에서 수질관리를 위한 적극적인 정책이 유효함을 시사한다. 본 연구에서는 제주도 지하수의 질산성질소 오염관리를 위한 적정 방안을 제안한다. The spatio-temporal variations of nitrate concentrations in groundwater of Jeju Island were evaluated by an analysis of time series groundwater quality data (N = 21,568) that were collected from regional groundwater monitoring (number of wells = 4,835) for up to 20 years between 1993 and 2015. The median concentration of NO 3 -N is 2.5 mg/L, which is slightly higher than those reported from regional surveys in other countries. Nitrate concentrations of groundwater in wells tend to significantly vary according to different water usage (of the well), administrative districts, and topographic elevations: nitrate level is higher in low-lying agricultural and residential areas than those in high mountainous areas. The Mann-Kendall trend test and Sen’s slope analysis show that nitrate concentration in mid-mountainous areas tends to increase, possibly due to the expansion of agricultural areas toward highland. On the other hand, nitrate concentrations in the Specially Designated Groundwater Quality Protection Zones show the temporally decreasing trend, which implies the efficiency of groundwater management actions in Jeju. Proper measures for sustainable groundwater quality management are suggested in this study.

잣나무 交雜育種 내지 選擇育種에서 利用되는 人共交雜에 關한 基礎硏究의 一環으로 잣나무 花粉의 最適發芽條件을 究明하기 爲하여 人共培地를 利用, Agar, Sucrose 및 Raffinose 濃度를 달리하여 發芽試驗을 했든 바 다음과 같은 結果를 얻을 수 있었다. 1. Agar培地에서의 花粉發芽率은 0.5% 濃度에서 75.72%로 가장 높았으나, 培地造成時疑固가 안되는 關係로 花粉發芽力 調査를 위해서는 1.0%濃度(發芽率 67.4%)가 適當하며, 花粉管伸長에 있어서는 1.0%(花粉管伸長 170.5μm)와 1.5%(花粉管伸長 172.8μm) 濃度의 培地가 가장 適當하다. 2. 花粉發芽率에 最適한 Raffinose의 農道는 1.0%(花粉發芽率 81.7%)었으며, 花粉管伸長에 最適한 Raffinose의 濃度는 10%(花粉管伸長 183.7μm)였다. 3. 花粉發芽率 및 花粉管伸長에 最適한 Sucrose의 濃度는 15%(花粉發芽率 89.2%, 花粉管伸長 182.1μm)였다. This study was carried out to investigate the effect of different concentrations of agar, raffinose and sucrose on pollen germination rate and pollen tube elongation in Korean white pine (Pinus koruiensis Sieb. et Zucc.). The highest rate of pollen germination was obtained in the medium supplemented with 0.5% agar. However, because of the poor colloidal state of 0.5% agar, 1.0% agar was recommended for pollen germination and 1.5% for pollen tube elongation tests. The highest pollen germination rate of 81.7% was obtained in the medium with 1% raffinose and the best tube elongation of 183.7 pm was obtained in the medium supplemented with 10.0% raffinose. Sucrose concentration of 15% was found to be optimum for pollen germination as well as pollen tube growth.

현상훈,이동아 연세대학교 산업기술연구소 1990 논문집 Vol.22 No.2

Ba-ferrite was synthesized at the relatively low temperature of 680℃ by the emulsion-charring method. Using the mixed oil phase(vol. ratio of kerosene/mineral oil=2/1), the synthesized powders were narrow-sized and unagglomerated. When powders were heat-treated at 1100℃, they grew to a hexagonal plate form with the size of 0.3-0.5㎛. The maximum theoretical relative density(89.7%) of the sintered Ba-ferrite was obtained when synthetic powders were sintered at 1300℃ after heat-treating at 1100℃, Ba-ferrite powders showed the best sinterability when they consisted of clear hexagonal plate forms without aggolomeration. The emulsion-charring technique should be evaluated as a very effective method for the preparation of fine powders such as Ba-ferrite easily agglomerated.

Surfactant washing process being operated in ex-situ mode could be appropriate one of the most effective remediation alternatives for NAPLs(non-aqueous phase liquids) in soil. The adsorption of sufactants has been concern of the reduction of expenditure and the increase of efficiency. Through the result of estimating the extent of adsorption of surfactants to soils, notion sufactants showed higher adsorption to soils than anion surfactants. From the results of evaluating which model could explain the surfactant adsorption to soils, it was determined that anionic surfactants were described well with Langmuir adsorption isotherm model, while nonionic surfactants were with Freundlich model.

보안위협 모니터링을 위한 AI 데이터셋 구성방안 연구

한상현, 조인준 배재대학교 공학연구소 2021 공학논문집 Vol.23 No.1

Cyber-attacks are evolving into a form of a long-term continuous attack by forming a dense group. However, there are cases of being defenseless against hacking attacks due to the lack of information on vulnerabilities exposed to security threats. In addition, organizations and companies with limited assets and response capabilities are often unable to take action due to the lack of measures to respond to such attacks. To solve this problem, we create a shared dataset by collecting various vulnerability information that has been disclosed, and after learning AI, we intend to present information on security vulnerabilities and effective detection and response methods for hacking attacks targeting vulnerabilities. 사이버 공격은 치밀하게 집단을 구성하여 장기간 지속적인 공격을 하는 형태로 진화하고 있다. 하지만 보안위협에 노출된 취약점들에 대한 정보 부재로 해킹공격에 무방비로 당하는 사례도 발생하고 있다. 또한 자산 및 대응역량이 제한된 기관 및 기업들은 이러한 공격에 대응할 수 있는 방안 부재로 조치를 할 수 없는 경우가 상당히 많다. 이러한 문제점을 해결하기 위해 공개되어있는 각종 취약점 정보들을 모아 공유 데이터셋을 만들어 AI 학습 후 보안취약점에 대한 정보와 취약점을 노린 해킹공격에 대한 효과적인 탐지와 대응하는 방안을 제시하고자 한다.

성장기 골격성 Ⅰ급 부정교합 환자의 정모두부방사선 계측의 특징

성상진,문윤식,김정국,정현성 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.2

악안면 기형과 부정 교합의 성공적인 교정 치료를 위하여 안모의 3차원적인 평가가 필수적이지만 교정의사는 주로 측모두부방사선사진에 기초한 진단 및 치료계획에 익숙하다. 이는 정모두부방사선사진에 관한 계측치, 악골의 폭경 성장에 관한 지식과 임상적 의의에 대하여 관심이 부족한 때문으로 생각된다. 본 연구에서는 골격성 I 급 부정교합으로 진단된 6세에서 16세 사이의 남자 130명과 여자 171명을 대상으로 정모두부방사선사진 상의 두개골 및 상하악골의 폭경을 계측하여, 연령과 경추골 발육지표(CVMI)에 따른 변화 양상을 알아보았다. 다항 회귀모형(polynominal regression models)과 변수선택법(method of variable selection)을 이용하여 적합한 회귀모형(regresslon model)을 각 성별에서 선택하고 이를 이용하여 연령에 따른 각 계측치의 평균 및 개별 계측치(individual measurement)의 70% 신뢰구간(confidence interval)을 추정하여 그래프로 작성하였으며, 다음과 같은 결과를 얻었다. 1.모든 폭경 계측치는 나이 또는 CVMI의 증가에 따라 점차 증가하였으며,6세부터 16세까지의 총변화량은 상악골 폭경보다는 하악골 폭경이 그리고 여자보다는 남자에서 더 많은 경향을 나타내었다. 2.Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio는 연령과 CVMI에 따른 남녀간의 유의차가 없었다. 3.회귀모형을 이용하여 나이에 따른 남녀 계측치의 평균 및 신뢰구간을 70%로 추정하여 상악골폭경,하악골 폭경, Mx-Mn difference, Mx/Mn ratio에 대한 그래프를 얻었다. 4.한국인의 상하악골 폭경은 성장기 동안 서양인에 비하여 큰 경향을 나타내었다. 본 연구의 결과를 성장기 부정교합 환자의 폭경 성장 평가와 폭경 부조화의 진단에 이용한다면 치아 석고모형 만을 이용하는 한계를 적절히 보완할 수 있다고 생각된다 Three dimensional analysis of malocclusion and craniofacial deformation is essential for the successful orthodontic treatment. But the orthodontists are not familiar with diagnosis and treatment plane based on lateral cephalometric analysis. Since orthodontists do not posses a sufficient knowledge in standard value of posteroanterior cephalometric analysis and of clinical importance for transverse jaw growth. In this study male(n=130) and female(n=171) aged from 6 to 16 and diagnosed as Class I malocclusion were selected to analysis width of cranium, maxilla and mandible on the posteroanterior cephalogram. The changes as a function of chronologic age and cervical vertebrae maturity index(CVMI) were examined. The proper regression model was selected by sex with polynominal regression models and method of variable selection. Mean of each measurements and 70% confidence interval of individual measurement according to age was assesed and a graphs were made. Results are as follows : 1.All the measurements for the width are gradually inclesed as increase in chronologic age and CVMI. From the total amount of change between age 6 and 16, there is a tendency that mandibular width is broader than maxillary width and the width of male is broader than female. 2.There is no statistically significant sexual difference in Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio according to age and CVMI. 3.Mean of each measurement and 70% confidence interval of individual measurement according to age and sex were assessed and graphs were made for maxillary width, mandibular width, Mx-Mn difference, Mx/Mn ratio. 4.The width of maxilla and mandible in Korean children are broader than Western children during growth period.

This study is to evaluate the existing methods to determine the design capacity of the multi-branched water transmission systems. Three types of methods are generally used to determine the design capacity of water transmission systems. The first method is that total average day demand and peak factor of whole area is considered to estimate total maximum day demand, and then it is assigned to each pipe in the system. The second method is that total demand for each pipe in the system is calculated by adding up maximum day demand of each area. Because the calculation of design flow for each pipe is simple and convenient, this method is generally used for the design currently. The third method is that the each proper peak factor for each pipe in the system are estimated to predict maximum day demand of each pipe. In this study, two real water transmission systems were considered as study areas, and three methods were applied. The first method tends to underestimates the design capacities especially for branch pipes. On the other hand, the second method tends to overestimates the design capacities for most pipes. As a result, it is found that the third method generates most reasonable design capacities for each pipe. However, mass balance for the analysis of water transmission systems can not be satisfied automatically in the third method. Therefor, dummy nodal flows method are suggested to satisfy the Mass Balance Equations in this study.
