2015년 3월 5일 리퍼트 주한 미국대사 테러사건과 2월 25일 세종시 엽총 사건으로 3명이 사망한데 이어 2월 27일 화성 남양에서도 엽총살인사건이 연이어 발생하며 우리 사회도 더 이상 총기로부터 안전지대가 아니라는 것이 현실화 되고 있다. 국제적으로는, 2015년 1월 18세의 김00이 자발적으로 가입한 이슬람 수니파 원리주의 무장단체인 이슬람국가(IS)등 국제 테러조직으로부터 우리나라도 더 이상 테러로부터 안전지대가 아니라는 우려가 높아가고 있다. 우리나라 경찰위기협상은 1988년 올림픽을 대비하여 대테러 위주로 창설 운영되어 왔으나, 20여 년간 대테러 사건은 한건도 발생하지 않으면서 존재에 대한 회의 및 발전 방향에 대한 논의가 활발히 이루어지고 있는 시점이다. 우리나라는 각종 살인 테러 강도 등 위기상황을 해결하기 위해 전통적인 물리력 행사가 여전히 선호되고 있고 전술적 역량을 강화하고 있다. 그러나, 국민의 신체와 재산을 보호하는 경찰의 기본 임무를 수행하기 위해서는 미국 등 선진국에서 강조하는 위기협상 기법에 대한 교육 확대로 어떤 사건이 발생하던지 초기에 위기협상이 가능한 체계 확립이 필요하다. 본 연구에서는 최 일선 경찰관들이 기본 협상가로서의 역할을 수행할 수 있도록 경찰의 위기협상 운영 실태를 파악하고, 내부 교육 자료 및 언론을 분석하여, 경찰 위기협상의 교육, 선발 등 발전 방향에 대한 대책을 제시하고자 한다.

Planetary boundary layer height (PBLH), produced by the Local Data Assimilation and Prediction System (LDAPS), was verified using RawinSonde (RS) data obtained from observation at Daegwallyeong (DGW) and Sokcho (SCW) during the International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic winter games (ICE-POP 2018). The PBLH was calculated using RS data by applying the bulk Richardson number and the parcel method. This calculated PBLH was then compared to the values produced by LDAPS. The PBLH simulations for DGW and SCW were generally underestimation. However, the PBLH was an overestimation from surface to 200 m and 450 m at DGW and SCW, respectively; this result of model's failure to correctly simulate the Surface Boundary Layer (SBL) and the Mixing Layer (ML) as the PBLH. When the accuracy of the PBLH simulation is low, large errors are seen in the mid- and low-level humidity. The highest frequencies of Planetary boundary layer (PBL) types, calculated by the LDAPS at DGW and SCW, were presented as types Ι and II, respectively. Analysis of meteorological factors according to the PBL types indicate that the PBLH of the existing stratocumulus were overestimated when the mid- and low-level humidity errors were large. If the instabilities of the surface and vertical mixing into clouds are considered important factors affecting the estimation of PBLH into model, then mid- and low-level humidity should also be considered important factors influencing PBLH simulation performance.

본 논문은 한국의 수도권공항인 김포국제공항, 인천국제공항과 청주국제공항(2012년부터 2014년가지 국무조정실, 재경조정실, 재정경제부, 건설교통부 등 관리 경제부처를 필두로 12부4처2청 등 49개의 중앙행정기관이 2014년까지 순차적으로 이전하게 되는 행정중심복합도시인 세종시의 관문 역할을 하게 됨)과 일본의 수도권공항인 나리다국제공하, 하네다(동경)국제공항의 현황과 문제점, 한 일간 수도권공항간의 협력내용과 상호관계, 본 연구과제에 대한 다각적인 면에서 검토한 개선안 등을 순서대로 제시하였다. 특히 본 연구과제에 대한 개선 방안으로는 (1)한 일간 항공자유화협정의 조속체결, (2) 새로운 항로개설과 저 운임항공회사(LCC)의 운항과 대책, (3) 양국 수도권공항들의 효율적인 이용계획, (4) 동북아시아의 항공시장에 있어 상호협력관계도 설명하였다. 1990년대부터 한 일 수도권공항간의 항공여객과 화물의 수송량은 극적으로 증가하고 있으며 이와 같은 추세는 양국의 경제성장을 촉진시키고 있다. 그러나 항공수송에 있어 양국의 수도권공항이 요구하고 있는 항공수요에 부응하기 위한 항공기의 좌석과 공항의 주기장은 아직도 충분히 확보되지 못하고 있다. 또한 수도권공항의 능력, 안정성확보 및 환경문제도 제기되고있다. 특히 각 나라의 수도권공항은 그 나라 국력의 상징이며 출입국을 하게 되는 관문이기 때문에 여객의 편의성과 신속성을 최대한으로 확보되어야만 한다. 아시아의 항공수송시장은 무제한경쟁시대에 접어들고 있어 아시아각국 들은 계속 허브공항의 확장개발계획에 노력을 집중하고 있으며 이와 같이 계속되고 있는 공항확장 개발계획의 경쟁을 극복하고 성공적으로 수행하기 위하여서는 한국과 일본간에 보다 긴밀한 협력시스템의 구축이 필요하다고 본다. 동북아시아의 항공시장에 있어 여객들의 편의와 빠른 여행을 지원하기 위해 김포공항과 하네다공항간의 정기 셔틀항공편의 증편과 청주국제공항과 하네다공항간의 정기 셔틀항공편의 개설을 위하여 한 일간에 새로운 "오픈 스카이협정" 의 체결이 바람직하다고 본다. 한걸음 더 나가 김포공항과 상해의 홍챠오공항 간에 정기 셔틀항공편의 연내 취항 및 내년 북경 올림픽을 대비하기 위하여 김포공항과 북경공항간의 정기 셔틀항공편의 개설과 일본도 금년 10월8일부터 하내다공항과 상해의 홍챠오공항 간에 정기 셔틀항공편의 의 취향과 하내다공항과 북경공항간의 정기 셔틀항공편의 개설을 추진하기 위하여 한 일 중 3국간에 상호 협력하여 새로운 "오픈 스카이협정" 의 체결을 종합적으로 검토되어야만 할 시기가 왔다고 본다.

"A Case Study of Center of Gravity(COG) when Performing Uchimata(inner thigh reaping throw) by Posture and Voluntary Resistance Levels(VRL) of Uke in Judo[II]". The purpose of this study was to analyze an angular momentum of trunk and lower extremity when performing uchimata by two postures and voluntary resistance levels(VRL) of uke(reciver) in Judo. The subjects, who were one male judoka(YH) for 1992 Barcelona Olympic Games Olympian(silver medalist), was filmed on two S-VHS 16mm video cameras(60fields/sec.) through 3-dimensional motion analysis methods, that postures of uke were shizenhontai (straight natural posture:NP) and jigohontai (straight defensive posture:DP), VRL of uke were 0% and 100%, respectively. The variables were angular momentum of trunk, lower extremity of attacking leg and supporting leg of tori(the thrower). The data of this study collection were digitized by SIMI Motion Program computed the mean values and the standard deviation calculated for each variables. When performing uchimata according to each posture and VRL of uke and classifying. From the data analysis and discussion, the conclusions were as follows : Angular momentum of trunk when performing uchimata was showed the largest among another angular momenta, and the posture displayed more different than resistant of uke(reciver), but the pattern similar in judo. Angular momentum of trunk of X axis was the largest and Y, Z axis order. Angular momentum of attacking the thigh-leg when performing uchimata was showed the largest among another angular momenta, and the posture displayed more different than resistant of uke(reciver), X axis and Y axis similar, but angular momentum of Z axis of thigh-leg the largest, in kake(application) event in 0% resistance of DP than other variables. Angular momentum in X,Y axis of attacking the lower-leg when performing uchimata was showed that the resistance level displayed more different than posture, but Z axis the largest, in kake(E3) phase in 0% resistance of DP than other variables as same thigh-leg, and the largest from tsukuri(set-up:E2) to kake(E3) phase. X and Z axis Angular momentum of supporting the thigh-leg were similar, regardless of posture and resistance of uke, but Y axis was resistance level. Angular momentum of supporting the thigh-leg was showed the largest in X axis, increased from EO event to E2, and decreased in E3, and angular momenta of Y, X axis were showed the largest in kuzushi(balance breaking) phase when performing uchimata. Angular momentum of supporting the lower leg were similar pattern, regardless of posture and resistance of uke, in Y axis, resistance displayed more difficult the position in NP, and showed opposite angular momentum in tsukuri phase. In conclusion, angular momentum of trunk when performing uchimata was showed the largest, and pattern was similar, regardless of posture than resistant of uke(reciver), magnitude and direction were different each other, and uchimata was Ashi -waza(foot and leg techniques) division but important of trunk action.
