Predicting where and when a crime may occur in an area of interest is one of many strategies of predictive policing. Multidimensional analysis, including CCTV, can overcome the limitations of hotspot prediction, especially of violent crimes. In order to identify the precursors of a crime, it is necessary to analyze dynamic data such as attributes and activities of people, social information, environmental information, traffic flows, and weather. These parameters can be recognized by CCTV. In addition, it provides accurate analysis of the circumstances of a crime in a dynamic situation, calculates the risk, and predicts the probability of a crime occurring in the near future. Additionally, it provides ways to gather historical criminal datasets, including sensitive personal information.
한상룡 가옥(현 가회동 백인제 가옥)의 원형과 조영개념
박상욱,Park, Sang-Wook 한국건축역사학회 2013 건축역사연구 Vol.22 No.4
The founder of the 'Paik In - Je House in Ga Hui Dong' in the Bukchon Hanok Village was found as Han Sang- Ryong (1880.11.14. ~ 1947.?) and the time when it was built was by the late June in 1913. Han Sang Ryong was the director of the HanSung Bank during the Japanese colonial period and he was the industrialist in the management committee and the economy coordinator in the economic area. The way how he could accumulate the huge amount of money was because his Uncle Lee Yoon Yong and Lee Wan Yong brothers were participating in various concessions under the protection of the colony government such as Chosun colonial government. Through seven years of preparation for building the mansion, the social function he presented to his house was 'the house built for the banquet hall'. He invited many celebrities of politics and economy to this house and built his fundaments for his social activity through interactions. To solve the construction concept, he used the way of 'duplicity and juxtaposition', and his mansion was reborn as a modernized urban Hanok through the reinterpretation by his program out of the old Confucian rules. Han Sang Ryong's mansion is significant and valuable in the period since it was a pioneer in challenging the creative housing in the developing stage of Hanok in early modern era, and the highest social level people were trying to show off through the Hanok as a product.

In order to increase endurance flight efficiency of long endurance electric powered UAV, main wing of UAV should have high aspect ratio and low structural weight. Since a spar which consists of thin and slender structure for weight reduction can cause catastrophic failure during the flight, it is important to develop verification method of structural integrity of the spar with the light weight design. In this paper, process of structural analysis using non-linear finite element method was introduced for the verification of structural integrity of the spar. The static strength test of the spar was conducted to identify structural characteristic under the static load. Then, the experimental result of the spar was compared to the analytical result from the non-linear finite element analysis. It was found that the developed process of structural analysis could predict well the non-linear structural behavior of the spar under ultimate load.

불균일계 액 - 액 접촉 계면을 통한 ester 의 알카리 가수분해 반응

Ethyl acetate와 n-butyl acetate의 25℃에서 알카리 가수분해 반응을 개량된 Lewis cell에서 행하여 화학반응을 수반한 물질전달 속도를 측정하였다. 측정한 물질전달 속도는 교반조의 교반속도에 무관하였고 이온강도 증가에 따라 감소하였으나 화학반응촉진 계수는 일정하였다. 측정한 화학반응 촉진계수를 경막설로부터 얻은 용질의 확산방정식의 근사해로부터 해석하여 ester의 알카리 가수분해반응의 2차 비가역 반응속도 정수를 얻을 수 있었으며, 그 값은 ethyl aeetate의 경우 0.041 ㎥/kgmol ·s, n-butyl acetate의 경우 0.338㎥/kgmol ·s 이었다. The rates of mass transfer with the alkaline hydrolysis of ethyl acetate and n-butyl acetate were measured by using a modified Lewis call. The rates of mass transfer with chemical reaction were independent of the speed of agitation, and the reaction enhancement factors were independent of the ionic strength. The second order reaction rate constants of ethyl acetate and n-butyl acetate could be obtained from an approximate solution of a diffusion equation by film theory, and their values were 0.041 ㎥/㎏ mol·s and 0.338 ㎥/kgmol·s, respectively.

교반기를 사용하여 n-butyl acetate의 알카리 가수분해반응의 액-액 불균일계에서 n-butyl acetate의 총괄물질전달속도를 측정하여 실험변수와의 관계를 고찰하고, 화학반응을 수반한 물질전달기구를 경막설에 적용하여 용질에 대한 확산방정식의 근사해로부터 구한 n-butyl acetate의 반응촉진계수의 이론값과 측정값을 비교하여 물질전달계수를 구하였다. 이로부터 분산용액의 액적 면적을 산출할 수 있었다. The rates of overall mass transfer of n-butyl acetate in the alkaline hydrolysis of n-butyl acetate were measured by using a mechanically agitated vessel in order to get the relationship between the mass transfer rates and experimental variables. The interfacial area between liquid-liquid heterogeneous phases could be obtained by comparing the theoretical values of reaction enhancement factor from an approximated solution of a diffusion equation based on the film theory with the experimental data.

It is identified that an initial person who built of 'Seoul Gyedong Modernized Hanok(former Min Hyeong-gi house)' used as 'Bukchon Culture Center' in present, was not Min Hyeong-gi, but his wife, Yu Jin-gyeong, and she built it when 8 years went on after his death(1879~1973), and the construction year was at the gate of Chuseok in 1921. Yu Jin-gyeong was Head Family's Eldest Daughter-in-law in family of Yeo Heung-min who was an influential person at the late Joseon Dynasty and was widow who had only son for 3 generations. And she built this house and moved to gain daughter and live futher grandchilds together in law in new nest. It is arranged that an annex surrounds with main building as the central figure. And this house emulates Yeonkeong-dang in backyard of the Changdeok Palace for 'preservation of main building' and Chim-bang-ga-toe applied on a bedroom in a palace is applied around nobleman family's the main room. It is rare case and expresses that a palace factor is borrowed. Yu Jin-gyeong's house is that a tradition Hanok is adjusted closely in city and central and basing mode as 'protective bedding' and building concept as 'a noble and protective architecture' is realized. So it has a character that development of Hangrang architecture is appeared and Head Family's Eldest Daughter-in-law widow of modern upper class had a special benefit. As well as, a meaning that it is experimental house based on tradition and is build of Hanok with housekeeping as the central figure for appear a form which has minimal Hangrang for housekeeping in yangban family of modern city, can be found.
Glutamate-Induced Serotonin Depletion in Fetal Rat Brainstem Cultures
박상욱,위명복,송동근,김용식,김영희,Park, Sang-Wook,Wie, Myung-Bok,Song, Dong-Keun,Kim, Yong-Sik,Kim, Yung-Hi The Korean Society of Pharmacology 1993 대한약리학잡지 Vol.29 No.2
흰쥐태 뇌간의 세포를 배양하여 glutamate에 6시간까지 노출시 glutamate의 농도 및 노출 시간에 의존적으로 세포내 5-HT 및 5-HIAA의 함량이 감소하였고, 배양액으로 LDH의 유출이 증가하였다. Tetrodotoxin은 glutamate의 작용을 차단하지 못하였다. NMDA 수용체 통로 봉쇄제인 MK-801에 의해 glutamate의 작용이 효과적으로 차단되었고, non-NMDA 길항제인 CNQX는 효과가 없었으므로, serotonin 신경세포에 대한 glutamate의 작용은 NMDA 수용체의 자극에 의한 것으로 사료된다. Exposure of dissociated cultures from fetal rat brainstem to glutamate for upto 6 h decreased cellular contents of 5-hydroxytryptamine and 5-hydroxyindoleacetic acid in a concentration- and time-dependent manner. In addition, glutamate induced lactate dehydrogenase leakage. Tetrodotoxin did not block the effects induced by glutamate. MK-801 $(1{\mu}M)$, an N-methyl-D-aspartate (NMDA) channel blocker, but not 6-cyano-2,3-dihydroxy-7-nitro-quinoxazoline $(CNQX;\;3{\mu}M)$, a non-NMDA receptor antagonist, blocked glutamate-induced effects, indicating that these glutamate-induced responses are mediated through NMDA receptors.
