The purposes of this study are to analyze the meanings of urban spaces which are the background of the Korean films, and to capture the interactions of ordinary culture and urban spaces. By reading urban spaces through films, it is possible to understand the variety of experiences that are hardly captured with direct eyes, specific and vivid urban images, and various events formed by the interactions of spaces and people. The scope of the study is the urban spaces revealed in Korean films portraying cities after the 1960's as their settings, and the total of 18 films was selected with every $4{\sim}5$ films for each time stage. With the selected films, analytical meanings were developed with considering three aspects; 1) phylogenetic meaning that simply reflects social-cultural and historical background, 2) the outer strum meaning that concerns the situation of special background and film scene, and 3) metaphorical and metanymic meaning on films. According to the appearance frequency, spatial backgrounds of film scenes are mainly alleys, main streets, railroad, loft, and riverside. And then the connection between spaces and meaning clusters was grasped, and reflected meanings were derived for every spaces. And the meaning of urban space in films was analyzed based on the meaning of developments and outer stratum. The fundamental characteristics and feelings of people in media such as films are more emphasized than in real world. Urban space is not considered as a simple visible shell, but is recognized as 'a real situation' created by people. The intension of this study was to open the possibility of the various views of urban spaces. The construction of the urban space should be approached from a perspective of creating new places at where the space and human beings interact with considerations of stories of various human lives. I hope new vistas can be opened up for the research subjects and methodologies about the hereafter study of urban spaces through the mutual communications with various adjacent regions including films.

'SMART 치안'이란 범죄통계 등 치안 관련 데이터베이스를 '전략적 관리', '분석과 연구', '과학기술'을 반영하여 수집 분석하고 활용함으로써 한정된 경찰력을 선택과 집중에 따라 운영하는 치안 활동을 의미한다. 최근 여성 1인 가구 증가에 따른 대검찰청의 '범죄분석'을 기준으로 성범죄 건수는 두 배 이상 증가하였다. 이러한 흐름 속에서 지역별 특성에 적합한 '여성안심특별시 3.0'의 성범죄 예방 프로그램을 구축하기 시작했다. 그러나 여성들에게 홍보 및 이용 실적이 저조하고, 실질적 효과성이 나타나기 위한 정책으로는 부족하였다. 앞으로 미래 경찰이 수행해야 할 시스템으로 ICT에 접목하여 자율주행차 또는 드론으로 경호를 하며, 안전하게 귀가를 담당 할 수 있는 범죄예방 시스템을 제안하였다. 이 시스템에 적용하기 위한 좁은 골목, 전깃줄 등 주변 환경이 자율주행자동차 및 드론을 운영하기에 어려운 점이 많으나, 인공지능 기술을 적용시 충분히 극복하여 운영할 수 있으리라 생각된다.

CoFeNi 합금은 HDD, MEMS 분야에서 head core 재료로 쓰이는 permalloy(FeNi)합금보다 뛰어난 우수한 자기적 특성을 가진 재료로써 최근 많이 연구되어지고 있다. 전기도금된 CoFeNi합금 박막의 열처리에 따른 미세구조 변화와 결정학적 특성이 자기특성에 미치는 영향을 조사하였다. 삼원계 합금을 열처리하면 전기도금 시 결정의 크기와 결정구조의 변화가 자기특성에 영향을 미친다. 이를 조사하여 열처리를 통하여 얻어지는 CoFeNi계 박막의 자기 특성을 향상시키고자 하였고, $300{\sim}400^{\circ}C$까지 열처리를 함으로써 보자력을 최소화하고 포화자화 값을 증가시켰다. 포화자화 값의 증가는 bcc상의 생성으로 야기되는 것으로 판단된다.

On October 29, 2022, a very large number of people gathered in Itaewondong, Yongsan-gu, Seoul, Korea for a Halloween festival, and as crowds pushed through narrow alleys, 159 deaths and 195 injuries occurred, making it the largest crushing incident in Korea. There have been a number of stampede deaths where crowds gathered at large-scale festivals, event venues, and stadiums, both at home and abroad. When the density increases, the physical contact between bodies becomes very strong, and crowd turbulence occurs when the force of the crowd is suddenly added from one body to another; thus, the force is amplified and causes the crowd to behave like a mass of fluid. When crowd turbulence occurs, people cannot control themselves and are pushed into he crowd. To prevent a stampede accident, investigation and management of areas expected to be crowded and congested must be systematically conducted, and related ministries and local governments are planning to establish a crowd management system to prepare safety management measures to prevent accidents involving multiple crowds. In this study, based on national data, a continuous digital topographic map is modeled in 3D to analyze the risk of crowding and present a plan for selecting high-risk walking routes. Areas with a high risk of crowding are selected in advance based on various data (numerical data, floating population, and regional data) in a realistic and feasible way, and the analysis is based on the visible results from 3D modeling of the risk area. The study demonstrates that it is possible to prepare measures to prevent cluster accidents that can reflect the characteristics of the region.

This study is to investigate the old buildings that have been built more than 50 years ago, targeting the areas of Seongan and Jungang-dong, the historic urban area of Cheongju. Their types and distribution characteristics are as follows. 1) First, the old buildings existing in downtown Cheongju account for 21.4% of 1,070 out of the total 5,000 buildings. Among them, wooden buildings before the 1950s accounted for 60% of them, resulting in severe aging. 2) Second, by use, 728 detached houses and 276 neighborhood living facilities account for 93.8% of the total, with 16 offices and 12 religious facilities. By structure, there are wood 65%, masonry 30%, and reinforced concrete 5% (54 buildings). By number of floors, the first floor 90%, the second floor 7.3%, and the third floor or higher 2.7% (30 buildings). The roof material is 51.6% of earthenware, followed by slate, cement, and slab. 3) Third, the old buildings are scattered all over the streets, and are concentrated in Namju-dong, Nammun-ro 1-ga-dong, Seoun-dong, and Sudong at the foot of Uamsan Mountain, a former refugee village. Also old buildings are distributed in Seoun-dong and Seokgyo-dong where hanok(korean traditional houses) are concentrated, in Namju and Nammunro 1 ga-dong blocks connected by alleys, and in cul-de-sac all over the place.

자기-저항 센서를 제작하기 위하여 Fe-Ni 합금과 Co-Ni 합금을 슬라이드 그라스와 Si wafer에 진공 증착하여 sensor element를 제작한 후 포화자속밀도($B_{s}$), 보자력($H_{c}$), 자기-저항 변화율 등을 조사하였다. 진공 증착된 Fe-Ni 합금 박막의 포화자속밀도는 0.65T이었으며 자화주파수 1 kHz에서 보자력은 0.379A/cm이었고 자냉처리 후 종방향 보자력은 0.370Acm(//), 횡방향 보자력은 0.390Acm(${\bot}$)로 변화되었다. 자기-저항 변화율은 박막의 산화로 인하여 매우 불안정하였다. 진공 증착된 Co-Ni 박막의 포화자속밀도는 0.66T이었으며 자냉처리 후의 종방향 보자력은 5.895Acm(//)이었고 횡방향 보자력은 5.898A/cm(${\bot}$)이었다. 한편 자기-저항 변화율(${\Delta}R/R$)은 $3.6{\sim}3.7%$로써 실온에서 매우 안정하였다. Fe-Ni 박막은 화학친화력이 강하여 자기-저항 센서 제조 공정에서 많은 문제점을 야기시키고 있으나, Co-Ni 박막은 화학친화력이 작고 자기-저항 효과가 뚜렷하여 고온용 자기-저항 소자 개발용 재료로 매우 적합할 것으로 사료된다.

Engineering phase of dairy housing systems has close connection with the milk produc- tivity of dairy cattle, the quality of milk, extension of dairy production systems, labor- saving in management of dairy cattle and the like. Moreover, the rate of investment of dairy housing facilities is of relatively high level, However, there has been almost no research effort for the improvement of engineering aspects of dairy housing systems in Korea. The purpose of this study is to find out general engineering problems and to recomm- end the improvement in dairy housing systems in Korea. Field survey by means of questionaire, direct measurements, taking pictures and sketching was conducted to get necessary information for the study. Kyung-ki Do region was firstly chosen for sampling area since it has included more than half of the number of dairy farms of the whole country. The results obtained are summarized as follows: 1. In overall dairy farm layout, the dwellings of workers were ignored in the light of sanitary environment 2. The layout of stalls in a dairy barn belongs mostly to the type of double-row face-out, which is compatible with the emphasis of manure disposal activities. 3. While the width and length of stalls were sufficiently close to the standard dimension, the width of mangers was much less than the standard dimension. 4. The width and depth of manure gutters and the width of working alleys were much. less than the standard dimension. 5. The mooring equipment was mostly in the classes of chain or rope. The watering equipment was not facilitated independantly except the one cese of using watercup. 6. The bucket milkers with one or two bucket milkers with the capacity of two cattles. each were used as milking equipment in most dairy farms. 7. There were only few milk rooms independently spaced from other space, in which the arrangement of milking equipment was much less than the standard condition. 8. The lounging ground area was averaged to be sufficient for the activity of dairy herd. 9. Silos for silage used during winter consisted of mostly bunker silos, trench silos and underground vertical silos. Ordinary vertical silos were considered for the farmers to be inconvenient for the labor saving. 10. From the view point of heat conservation and moisture removal within the dairy barns, windows were not flexible for the easy ventilation and ceiling part was not adequate for temperatur maintenance. 11. Waste treatment and disposal systems were not provided with most dairy farms, therefore the livestock waste pollution problems would be serious in the near future.

전자 기기의 솔더 접합부는 고온에서 작동하고 온도 변화와 부품의 열팽창계수 차에 의해 소성변형을 겪게 된다. 그리고 변형된 솔더는 다시 고온에서 회복과 재결정의 과정을 겪는다. 이와 같은 일련의 열적 기계적 과정은 솔더의 미세구조와 기계적 특성을 변화시킨다. 본 연구에서는 전자 장치가 실제 작동할 때 솔더의 기계적 특성 변화를 예측하기 위해 여러 종류의 무연 솔더와 복합 솔더 (composite solder)의 미소경도 (micohardness)를 다양한 열적 기계적 환경에서 측정하였다. 측정된 무연 솔더에는 Sn, Sn-0.7Cu, Sn-3.5Ag-0.7Cu, Sn-2.8Ag-7.0Cu (복합 솔더), Sn-2.7Ag-4.9Cu-2.9Ni (복합 솔더)가 포함되어 있다. 솔더 시편은 $0.4{\~}7^{\circ}C$/sec의 냉각속도로 주조되었고 $30{\~}50\%$의 압축변형을 가한 후 $150^{\circ}C$에서 48시간 열처리하였다. 미소경도는 $25{\~}130^{\circ}C$에서 측정하였다. 각 시편의 미세구조 역시 관찰하여 미세구조와 비교하였다.
