This study examined sexual violence characteristics among the individuals who utilized victim support services provided by National Rape Crisis Intervention Centers in Korea. The study is the part of a Korean longitudinal study on sexual assault characteristics and its implications for post-abuse adjustments, which is supported by Korean Mental Health Technology R&D Project. Eleven national rape crisis centers nationwide and 29 NGO's participated in the study. The participating centers provided the data on sexual abuse characteristics from their standardized case management system. The cases were randomly selected from the system. Total of 1077 cases were gleaned from the system and utilized for this analysis. Results indicated that the abuse characteristics differed by victims' age (children, adolescent vs. adults) as well as relationship with perpetrator. We could identify six different profile groups based on the detailed violence characteristics. The results assured us of the importance to understand the detailed characteristics of sexual violence and the old notion that 'one size may not fit all'. The results from the profile analyses may have important implication for developing victim support programs and appropriately allocating agency resources according to the different profiles of the service users.

가뭄은 국민생활 및 경제 등에 막대한 손실을 초래하며, 지역사회 공동체나 사회기능에 심각한 영향을 끼칠 수 있는 재해이다. 가뭄피해 최소화를 위해서는 단기대응, 복구지원 등의 사후대책에서 사전대비 및 예방으로의 정책 전환이 필요하며, 이러한 정책 수립을 뒷받침하기 위해서는 가뭄에 따른 정량적인 피해영향 평가가 우선적으로 필요하다. 하지만 가뭄 피해의 범위 및 형태는 워낙 광범위하기 때문에, 피해추정을 위한 잣대라 할 수 있는 영향평가 기법조차 제대로 정립되지 못하고 있는 실정이다. 국내에서는 분야별(기상, 농업, 수문)로 지수화 된 지표를 이용한 가뭄 평가가 주로 수행되고 있으며, 경제적 영향평가는 방법론에 대한 시범 연구 수준이다. 가뭄기록조사 등 과거 가뭄피해 자료에서도 피해액의 금액환산이 되지 않은 사례가 대부분이며 급수차지원, 관정개발 등 사후복구비 위주의 일부 자료만이 피해금액으로 제시되어 있을 뿐이다. 댐, 저수지 등에 의한 용수공급 안정성으로 인해, 기상학적인 가뭄이 즉시 물부족으로 인한 피해로 이어지지는 않지만, 물부족이 발생하거나 부족량이 예측되는 상황에서 피해규모를 시스템적으로 추정 및 비교할 수 있는 기법 개발의 필요성에 의해 잠재피해액 개념의 공급지장비용 추정기법을 개발하였다. 공급지장비용 또는 편익 도출을 위한 이론적 배경으로, 경제적 가치 또는 파급효과를 분석하기 위한 방법은 경제학적 접근법과 비경제학적 접근법으로 구분된다. 경제학적 접근법에서 사용하는 진술선호 기법의 경우 전국을 대상으로 설문 등의 과정을 거쳐 지불의사액을 도출하는 과정이 필요하기 때문에 많은 조사비용이 소요된다. 비경제학적 또는 공학적 접근법으로 분류되는 대체비용법은 이론적 배경이 약하고 대체항목의 선택에 주의가 필요하다는 단점이 있으나, 물가자료, 산업통계, 수자원통계 등 기초자료의 주기적 업데이트가 유리하며, 정신적 피해를 제외할 경우 피해비용 추정결과의 편차가 진술선호기법 보다는 작은 장점이 있다. 본 연구에서는 피해비용의 과대추정에 유의하여 대체비용법에 기반한 일본 후생노동성의 감 단수피해추정기법을 우리나라 자료에 맞게 수정하여 공급지장비용을 추정하였으며, 경제학적 접근법에 의한 용수의 한계가치비용 등과 비교를 통해 적용성을 검토하였다.

A two-color particle image velocimetry (PIV) has been developed for measuring two dimensional velocity flowfields and applied to a Mach 2.0 supersonic nozzle. This technique is similar to a single-color PIV technique except that two different color laser beams are used to solve the directional ambiguity problem. A green-color laser sheet (532 nm: 2nd harmonic beam of YAG laser) and a red-color laser sheet (619 nm: output beam from YAG pumped Dye laser using Rhodamine 640) are employed to illuminate the seeded particles. A high resolution (3060${\times}$2036) digital color CCD camera is used to record the particle positions. This system eliminates the photographic-film processing time and subsequent digitization time as well as the complexities associated with conventional image shifting techniques for solving directional ambiguity problem. The two-color PIV also has the advantage that velocity distributions in high speed flowfields can be measured simply and accurately by varying the time interval between two different laser beams due to its high signal-to-noise ratio and thereby less requirement of panicle pair numbers for a velocity vector in one interrogation spot. The velocity distribution in the Mach 2.0 supersonic nozzle has been measured and the over-expanded shock cell structure can be predicted by the strain rate field. These results are compared and analyzed with the schlieren photograph for the velocity distributions and shock location.

In recent years, as rainfall is concentrated and rainfall intensity increases worldwide due to climate change, the scale of flood damage is increasing. Rainfall of a previously unobserved magnitude falls, and the rainy season lasts for a long time on record. In particular, these damages are concentrated in ASEAN countries, and at least 20 million people among ASEAN countries are affected by frequent flooding due to recent sea level rise, typhoons and torrential rain. Korea supports the domestic flood warning system to ASEAN countries through various ODA projects, but the communication network is unstable, so there is a limit to the central control method alone. Therefore, in this study, an artificial intelligence-based flood prediction model was developed to develop an observation station that can observe water level and rainfall, and even predict and warn floods at once at one observation station. Training, validation and testing were carried out for 0.5, 1, 2, 3, and 6 hours of lead time using the rainfall and water level observation data in 10-minute units from 2009 to 2020 at Junjukbi-bridge station of Seolma stream. LSTM was applied to artificial intelligence algorithm. As a result of the study, it showed excellent results in model fit and error for all lead time. In the case of a short arrival time due to a small watershed and a large watershed slope such as Seolma stream, a lead time of 1 hour will show very good prediction results. In addition, it is expected that a longer lead time is possible depending on the size and slope of the watershed.

This study is designed to find out the protection system of intangible cultural property as the current national policy and analyze the foundational problems in order to suggest the future vision in a way of transmitting the traditional cultural heritage to the descendants, based on the policy support for the intangible cultural property under the control of Commission for Ibuk 5-do (5 Northern Provinces of Korean peninsula). The research issue is first, the aging of the holders of the important cultural properties in Ibuk 5-do and the overcoming of the incomplete transmission system. The second issue is the protective policy of the transmission from the national perspective and the justification of the government's financial support. The third issue is the development of cultural contents by using the intangible cultural properties in Ibuk 5-do and the suggestion of the creative development for the resourcing of culture. As for the research methods, reference research and analysis on interview data and data from the related entities was done were analyzed and the results were actively adopted. The research results showed the followings to be required; first, the aged holders of the cultural properties shall be treated well and at the same time, the holders recognized to hold the transmission ability shall be dually designated. Second, the training system for the younger generation to keep the traditional cultural heritage shall be established; Third, the educational program and school education shall be extended so that the importance of the transmission of the intangible traditional cultural properties in Ibuk 5-do (northern 5 provinces of Korea) shall be recognized; Fourth, the recording system shall be constructed and its application system shall be required. In the end, in order for such development methods to be implemented effectively, active government support is desperately required.

Pedestrian movement of passengers using smart card within stations can be divided into three types of activities - straight ride and alight, line transfer, and station transfer. Straight ride and alight is transfer activity for which the card terminal and embarking line are identical. In this case, straight ride occurs at the origin station and straight alight occurs at the destination station. Line transfer refers to activity in which the subway line embarked on by the passenger is different from that which is disembarked. Succinctly, line transfer is transfer at a middle station, rather than at origin or destination stations. Station transfer occurs when the card terminal line and embarking line are different. It appears when station transfer happens at the origin station as starting transfer, and at the destination station as destination transfer. In the case of Metropolitan smart card data, origin and destination station card terminal line number data is recorded, but subway line data does not exist. Consequently, transportation card data, as it exists, cannot adequately be used to analyze pedestrian movement as a whole in subway stations. This research uses the smart card data, with its constraints, to propose an analysis model for passenger pedestrian movement within subway stations. To achieve this, a path selection model is constructed, which links origin and destination stations, and then applied for analysis. Finally, a case study of the metropolitan subway is undertaken and pedestrian volume analyzed.

This study analyzes the effect of the changes in traffic environments such as transportation speeds on the time-distance accessibility for the public transportation passengers. To do this, we use passenger transaction databases of the Seoul metropolitan public transportation system: one week for each of the three years (2011, 2013, and 2015). These big data contain the information about time and space on the traffic trajectories of every passenger. In this study, the time-distances of links between subway stations and bus stops of the public transportation system at each time are calculated based on the actual travel time extracted from the traffic-card transaction database. The changes in the time-distance accessibility of the integrated transportation network from the experimental results can be summarized in two aspects. First, the accessibility tends to decline as the year goes by. This is because the transportation network becomes more complicated and then the average moving speed of the vehicles is lowered. Second, the accessibility tends to increase on the weekend in the analysis of accessibility changes by day. This tendency is because the bus speeds on bus routes on the weekend are faster than other days. In order to analyze the accessibility changes, we illustrate graphs of the vehicle speeds and the numbers of passengers by year and day.

This study aimed to explore the association between obesity index and heart rate variability (HRV) in college-aged male smokers. A total of 85 male college students (> 10 cigarettes per day for at least 3 years) were participated in this study. According to a standardized protocol, body mass index (BMI), percent body fat (%BF), waist circumference (WC), and waist-to-hip ratio (WHR) were taken as obesity indices. Resting r-r interval was monitored for HRV analysis as an indicator of cardiac autonomic regulation. Compared with low WHR subjects, high WHR subjects had significantly lower values of rMSSD, pNN50, HF, and SD1, suggesting decreased parasympathetic activity. No such differences in LF/HF ratio were found between the WHR-based subgroups. Bivariate correlation analysis showed that obesity indices of WC, WHR, and %BF were significantly associated with rMSSD, pNN50, HF, and SD1, with a tendency for correlation coefficient to be higher with WHR than with WC or %BF. No significant association was found between BMI and HRV parameters indicative of parasympathetic activity. This study suggest that central obesity is significantly associated with decrease in parasympathetic activation, independent of BMI as an indicator of obesity, in male college smokers.

Based on the previous year's statistics, 37% of buildings in South Korea are aged over 30 years. As the number of the aging buildings increases, so does the need for maintenance. Building maintenance involves a significant number of works; the work of 'maintenance manager' accounting for the largest part. Currently, the maintenance history record is mostly in drawing or handwritten form which makes reviewing the data highly time consuming. Therefore, to improve the convenience of maintenance works and optimize historical data management, the existing maintenance process was analyzed. Problems were derived and a smart device-based automation model was established. In order to establish a smart device-based automation model, ① general flow of facility management process was analyzed and related articles were reviewed, ② current maintenance process was optimized, ③ functional block diagram of BIM Data, COBie Data, IoT, and AR-based automated maintenance management model was created, ④ a smart device-based automated maintenance management model was constructed, ⑤ finally, the above system was verified by testing the aforementioned model in the field site, evaluating the time required for the maintenance process and reviewing maintenance history data against the current one.

한국에서의 유가(儒家) 경전의 수용은 삼국시대에 시작되었으며, 이는 신라(新羅)시대 태학(太學) 교육 중의 한 과목이 "상서(?書)"였다는 "삼국사기(三國史記)"의 기록을 통해 알 수 있다. "상서(?書)"는 고대 정치제도 및 정치사상과 매우 긴밀한 관련을 갖는 경전인 까닭에 중국뿐만 아니라 한국에서도 통치자들의 시정방침(施政方針)상의 중요한 근간(根幹)이 되었다. 이러한 연유로 "상서(?書)" 연구를 통해서 경서 내용을 알게 될 뿐만 아니라 그 시대의 정치사상도 알 수 이해하게 될 것이다. 그런데 한국에 있어서 경학 연구는 중국과 달리 전통적 사서오경(四書五經) 혹은 십삼경(十三經)이 아니라 "사서삼경(四書三經)"을 중심으로 전개되었다. 또한 개별 경전에 대한 연구를 기준으로 살펴보면, "사서(四書)"의 경우, 특히 "논어(論語)"에 대한 연구가 집중적으로 이루어졌다. 삼경(三經)의 경우, "주역(周易)"이나 "시경(詩經)"은 이미 많은 연구가 이루어졌으나, 한국에서 "상서(?書)" 연구는 아직 전자만큼 활발히 이루어지지 못하고 있다. 또한 성균관대학교에 발간한 "한국경학자료집성(韓國經學資料集成)"을 살펴보면, 한국 경학 저술 총 145권 가운데 "상서(?書)" 부분이 22권을 차지하고 있다. 즉 거의 6분의 1이 "상서(?書)" 관련 저술이라고 할 수 있다. 본고는 "학술총람"과 공구서(工具書) 전자 시스템에 수록된 1901년부터 2014년 상반기에 이르기까지의 100여 년 동안 한국(韓國)에서 발표된 "상서(?書)" 관련 학술단행본 학위논문 학술지논문 등을 검토하고, 이를 통해 한국에서의 "상서(?書)"학(學) 연구(硏究)를 회고(回顧)하고 또 그 미래를 전망(展望)해 보도록 할 것이다. 전적으로 보면 한국 "상서(?書)"학 연구는 3가지를 포함한다. 첫째는 한국에서 중국 고전 "상서(?書)" 원전(原典)에 대한 탐구(探究)인데 이를 '중국 "상서(?書)" 연구' 라고 칭하였다. 둘째는 조선시대 유학자의 서경 저술을 중점 대상으로 연구하는 것으로 이를 '한국 "서경"학 연구'라고 이름 하였다. 셋째는 한국 이외 다른 나라 학자들의 조선시대 "서경" 저술에 대한 연구이다. 이상 3가지를 모두 대상으로 삼아야 온전한 한국 "상서(?書)"학 연구라고 할 수 있을 것이다. 향후의 연구 방향은 다음 네 가지로 정리할 수 있다: (1) 역본의 연구 (2)학파별 연구 (3)문헌적 연구 (4)경연과 과거시험의 각 나라 비교 연구이다. 한국 "서경"학에 대한 연구를 통해 우리는 조선시대의 사상과 문화 특히 정치사상을 파악할 수 있으며 또한 전통시대 동아시아 각국의 학문 양상까지도 인식할 수 있을 것이다. 요컨대, 아직까지 한국의 학계에서 한국 "서경"학을 중심으로 하여 이러한 측면을 밝히는 연구는 부족한 편이라고 할 수 있겠으며, 그렇기에 연구할 영역이 더욱 많은 셈이라고도 할 수 있는 것이다. 바로 이 연구영역들에 더욱 심혈을 기울여 앞으로 더 깊이 있고 폭 넓은 연구가 진행되기를 기대할 수 있게 되는 것이다.
