Among smart city services, the crime and disaster prevention sector accounted for the highest 24% in 2018. The most important platform for providing real-time situation information is CCTV (Closed-Circuit Television). Therefore, it is essential to create the actual CCTV surveillance coverage to maximize the usability of CCTV. However, the amount of CCTV installed in Korea exceeds one million units, including those operated by the local government, and manual identification of CCTV coverage is a time-consuming and inefficient process. This study proposed a method to efficiently construct CCTV's actual surveillance coverage and reduce the time required for the decision-maker to manage the situation. For this purpose, first, the exterior orientation parameters and focal lengths of the pre-installed CCTV cameras, which are difficult to access, were calculated using the point cloud data of the MMS (Mobile Mapping System), and the FOV (Field of View) was calculated accordingly. Second, using the FOV result calculated in the first step, CCTV's actual surveillance coverage area was constructed with 1 m, 2 m, 3 m, 5 m, and 10 m grid interval considering the occluded regions caused by the buildings. As a result of applying our approach to 5 CCTV images located in Uljin-gun, Gyeongsnagbuk-do the average re-projection error was about 9.31 pixels. The coordinate difference between calculated CCTV and location obtained from MMS was about 1.688 m on average. When the grid length was 3 m, the surveillance coverage calculated through our research matched the actual surveillance obtained from visual inspection with a minimum of 70.21% to a maximum of 93.82%.

The purpose of this study was to investigate the changes that family caregivers have experienced since using the Korean Long-Term Care Insurance(LTCI) system. In-depth interviews were conducted to determine how the services offered within the LTCI program had affected family caregiving and what changes they had incurred. Results from the qualitative content analysis show that the LTCI program significantly reduced the caregiving burden among family caregivers although burdens that family caregiver perceived varied greatly depending on the types of service that the family selected, and assigned family caregivers different identities and diverse roles(i.e., service user, family caregiver, certified care provider) depending on the service they use. The phenomenon of 'certified family care provider', which was not an intention of LTCI, demonstrates the practical need of elderly persons who require both care and the comfort of family and economic status of the family. Despite the positive impact of the LTCI policy on the family caregivers' burden and family relationship, the current LTCI system should be modified in order to better meet the needs of beneficiaries and their family caregivers.

미국은 이제까지 서구 백인문화 중심적으로 간호학을 발전시켜왔다. 그러나 국제적인 세계화 흐름과 함께 이제까지 경시되어 왔던 소수 민족들에게 차츰 관심을 모으고 있다. 이러한 간호학의 추세와 함께 재미 한인들의 증가는 간호학 내의 한인들에 대한 문화적 지식의 확대를 필요로 하게 하였다. 이민이라는 과정을 통해서 이민자들은 새로운 가치관. 태도. 사회적 규범을 획득하게 되는데. 이러한 변화는 신체적. 정신적 건강에 부정적으로 영향을 미치는 것으로 보고되고 있다. 또한 이러한 이민 적응과정에서 오는 어려움 들은 이민자 들이 건강관리를 효과적으로 하지 못하게 하는 주원인으로 보고되고 있다. 이 연구에서는 재미 한인들의 건강관리실천을 그들의 초기 이민 과정에서 겪게 되는 여러 경험에 초점을 맞추면서 면담조사와 사례 연구를 통하여 살펴보았다. 임의 표본 추출된 미국 캘리포니아주 오클랜드에 있는 한 한인 교회의 20명의 교민들을 대상으로 그들의 초기 이민경험과 건강관리 실천에 관한 면담 조사가 이루어졌으며 대상자 중 3인을 대상으로 하여 사례 연구가 이루어졌다. 연구 결과, 재미 한인들은 타이민자들에 비해 소규모 사업에 종사하는 경우가 많고 높은 취업 율에 비해 낮은 수인을 가지는 것으로 나타났다. 한인들은 타이민자들에 비해 좀 더 보수적이며 그들의 문화와 관습을 가능한 한 고수하는 것으로 나타났다. 또한 한인들은 사회 참여와 대인 관계에 있어서 한인 사회에만 한정되게 활동하는 것으로 나타났다. 재미 한인들은 한인 사회 내에서 강력한 사회적 유대관계를 유지하는 것으로 나타났으며, 가족의 영향력이 타민족들에 비하여 강한 것으로 나타났다 언어 장벽이 가장 큰 문제로 보고되고 있으며 비록 성공적으로 미국 사회에 적응을 하더라도 계속적인 경제적인 생존 노력과 사회적으로 소외된 그들의 위치는 그들의 삶을 계속해서 어렵게 하는 것으로 나타났다. 이러한 초기 이민 적응과정에서 오는 어려움 들은 그들의 건강을 비효과적으로 관리하게 만드는 것으로 나타났다. 첫째, 적절한 통역자를 사전에 선정, 이용함으로써 적절한 간호를 제공할 수 있도록 하여야겠다. 둘째. 한인을 대하는 간호 제공자들은 한인에 대한 문화적 지식을 겸비하고 그 지식에 근거를 둔 문화적으로 적절한 간호를 제공하여야 할 것이다. 셋째, 간호 제공자들은 한인들의 치료법 혼용을 이해하고 동시에 여러 치료법을 사용하는 경우. 잘 살펴서 적절한 조치를 취해야 할 것이다. 넷째, 가족관계를 사정하고 적절히 가족 구성원을 간소 목적을 위하여 사용할 수 있어야 하겠다 마지막으로 이들 내의 위험 집단을 우선적으로 파악. 접근하여야 할 것이다. 위험 집단으로는 경제적 문제로 적절한 의료 이용을 할 수 없는 저소득층, 문화적으로 열등한 위치에 있는 여성층과 초기 이민 적응에 가장 문제를 일으킬 소지가 있는 노년층을 들 수 있겠다. 이 연구는 몇 가지 제한점을 가진다. 첫째. 연구 대상자 선정이 어려워서 자원자를 대상으로 연구가 행해졌다. 둘째. 적은 수의 연구 대상자를 대상으로 연구가 행해졌다. 셋째. 연구기간이 짧았던 까닭에 좀더 상세한 사례 연구가 이루어질 수 없었다 좀 더 신뢰할 수 있는 표본 추출 방법을 통하여 선정된, 많은 연구 대상자를 가지고, 심도 있는 연구가 추후 반복적으로 이루어져야 할 것이다.

As a monumental building in the form of an arch, an archway has the characteristics of praise and honor. More and more historic, cultural and social connotations are given during the development of history. Four archways that are located on the middle route of the Red Gate Palace in the Mount Tai Scenic Area were chosen for research. Based on a literature review and field investigation with a visual analysis method, the physical attributes, spatial scale, perceptions and functions of the archways were discussed. The results were as follows: The archways in the research area are all made of stone. According to building location, they are classified into two types: Cultural archway and temple archway. Regarding functions, they are divided into symbolic archway, memorial archway and portal archway. From the point of view of form and scale, the Confucius Boarding Archway enjoys a higher standard than the other three. This reflects the importance of Confucian culture on Mount Tai. Regarding spatial scale, the archway becomes the focus in a restrictive linear space by an object-to-object and person-to-object comparison. Visitor experience of crossing the archways is strongly enhanced as it acts as entrance and exit, and it has the function of guiding sight since the arrangement of the archways further extend the line of sight. Couplets and inscriptions on the archways increase a sense of expectation for visitors on their way to the top of Mount Tai.

Purpose: Endoscopic ultrasonography (EUS) is a useful imaging procedure for the diagnosis of submucosal tumors in the stomach. The present study investigated the EUS features of benign and malignant gastrointestinal stromal tumors(GISTs) and assessed differences between the two groups. Materials and Methods: Thirty patients with a GIST in the stomach were included in the study (23 benign and 7 malignant GISTs). We compared characteristic EUS findings (tumor size, location of tumor, regularity of the outer margin, echoheterogeneity, presence of cystic spaces, echogenic foci and mucosal ulceration) between benign and malignant GISTs. Results: Tumor sizes over 40 mm were observed in $85.7\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.000). Intralesional cystic spaces were noted in $71.4\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.003). The outer margin was irregular in $71.4\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.014). $85.7\%$ of the malignant and $13.0\%$ of the benign tumors had an echo-heterogeneity in the tumor (P=0.001). The locations of tumor and the presence of echogenic foci or mucosal ulcerations were not different between the two groups. Conclusion: Tumor sizes over 40 mm, intralesional cystic spaces, irregular outer margins, and echo-heterogeneity in the tumor were significantly more frequent in malignant GISTs. EUS can provide informations in differentiating benign from malignant GISTs.

In this study, the behavior and safety of an existing tunnel and its facilities are investigated when a new tunnel adjacent to the existing tunnel is blasted. The design of the new tunnel puts priority on stability of the tunnel itself over the safety of the facilities which are installed within the existing tunnel such as jet fans. And thus, a detailed consideration on securing the safety of the existing facilities has been insufficient. An analysis on the types of traffic accidents in the last ten years shows that most incidents were due to the driver's improper response in emergency situations and unexpected obstacles. In consideration of this analysis, the safety of the facilities in the existing tunnel was secured by minimizing the charging amount for each hangfire and changing the excavation method of evacuation communication shelters to the large center hole cut blasting method to reduce blasting vibration. For a more quantitative analysis, measurement devices were installed inside the existing tunnel, at houses adjacent to the new tunnel, near jet fans in the existing tunnel. This enabled real time measurement of displacements of the existing tunnel, adjacent houses, and jet fans without interrupting traffic flow. Therefore, the improvements of charging amount for each hangfire, the blasting method, and the measurement method are suggested in this paper to secure the safety of the facilities in the existing tunnel when a new tunnel, located on a large city and adjacent to an existing tunnel, is designed.

Recently, the retail industry has created efficient store operations, and has differentiated customer service through the future store. The intelligence of these stores is being applied by using technologies such as the Internet of Things (IoT), and the business process is being improved through this. The process also focuses on efficient store operations and service developments to provide customers with shopping convenience. The change in trends in the industry means that domestic distribution has already reached maturity. Even in countries where retail industries are mature, such as the U.S. and Europe, recent trends are moving toward maximizing operational efficiency and customer service. The reason is that many retailers have already reached saturation and survived the competition. This paper is a study of a drive-through service for automation and efficiency in receiving service after ordering by a customer of the distribution store. When ordering a product being purchased by a customer, the product picking process is done in a timely fashion through a picking scheduling agent. When the customer enters the store parking lot, a service supports the entry of information and finding a parking place so the customer can quickly pick up the goods. The proposed service can be applied to a retail store drive-through system, the distribution store's delivery system, the digital picking system, and indoor/outdoor large parking management systems, and it is possible to provide one-dimensional customer service through the application of IoT technology.

간호원은 비록 그가 양호교사가 아니라고 하더라도 그가 처한 위치에서 거의 매일 건강교육을 실시하고 있다고 할 수 있다. 그러한 비정규직 교육은 상황에 따라 간호활동의 대상자들에게 수시로 별 준비 없이 실시한 경우도 있겠으나 효율적인 결과를 얻을 수 있는 체계적인 보건교육은 구체적인 학습목적과 교육과정이 교육적으로 미리 계획되어 있어야만 가능하다고 할 것이다. 양호교사의 기본적인 역할이 학교 구성원들의 건강증진과 질병예방에 있으며 효율적인 건강교육을 통하여 이러한 목적을 달성한다고 할 때, 양호교사는 자신을 그 학교공동체의 주된 건강교육자로 이해하고 학교에서 이루어지는 모든 보건교육 과정에 적극적인 참여를 하여야만 한다. 그러한 역할중의 하나는 보건에 관한 수업을 실시하는 학과목 교사나 담임교사들이 건강교육에 관련한 협의를 양호교사에게 요청하도록 적극적인 건강교육환경을 학교 내에 조성하여야 하는 일과 중요한 건강주제에 대하여서는 양호교사가 직접 수업을 교실에서 이끌어야 하는 것일 것이다. 이 논문에서 다룬 보건교육 교안 연구는 양호교사에게 또 건강에 관한 주제를 가지고 수업을 하는 일반교사에게 중학생의 건강교육 과정의 한 모델로써 사용하는데 도움이 될 것으로 본다. 건강교육 프로그램을 질병예방, 건강증진에 초점을 두어 설계한다고 할 때 건강교육의 주된 방향은 대상자 하나 하나의 생활에서 건강을 위한 바람직한 행위를 생활화하도록 하는 것이다. 이 목적을 학교에서 달성하기 위해서는 건강교육 프로그램을 통하여 학생들에게 건강에 대한 지식을 전달하고 그 지식 위에 건강을 위한 바람직한 행위를 하도록 동기를 부여하며 그러한 행위를 지속하도록 보강하는 것이 필요하다고 할 것이다. 사람들은 건강에 대한 지식이나 정보를 가지게 되면, 행위는, 그것에 상응하여 바람직하게 행할 것이라고 가정하기가 쉽다. 그리하여 건강에 대한 정보를 주는 것 건강교육을 했다고 간주하기도 한다. 그러나 실제적으로 건강을 위한 정보를 받고 지식을 가졌다 하더라도 바람직한 행위를 실천하지 않거나, 습관된 반건강 행위를 바꾸지 않는 경우가 많다. 그러므로 건강한 행위를 실천하기 위해서는 그에 대한 가치관이나 태도가 먼저 분명하게 세워져야 한다. 학생들의 경우에도 그 가치관이 확립되어야 하겠으므로 이를 위한 효과적인 교육방법이 제시된 교육안 모델이 있어야 할 것이다. 즉 건강문제에 대한 태도의 확립과 그에 따른 올바른 행위를 실천하도록 하기 위하여 구체적으로 치밀하게 계획된 건강교육 안이 연구되어 지는 것이 건강교육의 가장 중요한 과제중의 하나이다. 이 연구에서 제시하는 건강교육 프로그램에서는 많은 부분의 정보가 학생들 스스로에 의해서 수집되도록 하였다. 그렇게 함으로써 그들이 흡연에 관한 사실들을 스스로 명백하게 파악할 수 있었기 때문이다. 또한 소그룹 토의와 논쟁의 방법을 통해서 학생들이 흡연에 대해서 자신들의 생각하고 있는 것을 검토하여 올바른 판단을 하도록 하는 기회를 가질 수 있도록 하였다.

Many studies have been performed since the introduction of GPS in Korea. As a result, positioning using GNSS was fully proposed. On the other hand, most of these studies focused on accuracy but analytical studies on the GNSS status and the national GNSS infrastructure of Korea are lacking. In this study, the status of multi-constellation GNSS and National Geographic Information Institute's CORS (Continuous Operating Reference Station) were identified for the benefit and direction of GNSS infrastructure enhancement. As a result, it has been operating Multi-constellation GNSS, such as GPS, GLONASS, Galileo, COMPASS, and QZSS for surveying. In addition, improvement was presented by the number of satellites, precision, PDOP, etc. through the experiment about VRS and RTK using Multi-constellation GNSS. Upgrading the infrastructure for satellite surveying was identified as a priority consideration. In the future, if a Multi-constellation GNSS service is possible in VRS service, the satisfaction of public administration service will improve, which will contribute greatly to the advancement of a surveying infrastructure.
