The operation method of offline venues such as local festivals usually has problems such as the absence of real-time events and booth information, wasting time in the process of purchasing and receiving goods, and stagnating the movement of guests. This study increases the convenience of guests and managers by integrating all contents in the venue in the form of booth, thereby increasing the uniformity of event information and the efficiency of booth operation. In addition, a system was designed to minimize movement problems and improve performance by detecting the movement of guests within the venue and increasing the efficiency of arranging booths based on location data. It has been developed as a low-cost system that measures wireless packets with portable wireless LAN APs and control units. This has advantages in the operation of the venue, which consists of the installation and dismantling of variable booths in a short period of time. It is expected that the integrated operation of the venue will be utilized by linking the movement data of guests to activate visits and increase sales through data-based promotions.

다수 사업체의 출현과 데이터 통신의 증가로 통신사업자의 사업환경은 급속한 변화를 겪고 있다. 이러한 사업환경 변화에 비추어 시내전화 사업자는 기존 동선 구조의 가입자망을 초고속 서비스에 적합하도록 고도화시켜야 하는 필요성을 가지고 있다. 본 연구는 기존 동선가입자망을 광가입자망으로 전환하는데 따른 시내전화 사업자의 의사결정문제에 대하여 전략적 의사결정 방법론을 제시하고자 한다. 이를 위해 본 연구에서는 ADSL 비용 모형을 개발하여 도심지역을 대상으로 현재 동선구조의 가입자망을 고도화시키기 위한 기술적 대안에 대하여 경제성 분석을 실시하였다. 또한 2010년간의 가상의 시나리오를 설정하여 통신사업자의 이익을 극대화시킬 수 있는 진화방법을 도출하였다.

Changdeokgung Rear Garden is an important place to show the essence of the garden culture of the Joseon Dynasty. In the garden landscape experience, the restoration of the road completes the system of connecting the main spaces. Therefore, the restoration of the road requires accurate understanding of its creation, extinction, and maintenance. The purpose of this study was to detail the changes in the path that occurred in the Changdeokgung Palace Rear Garden from the late Joseon Dynasty to the modern and contemporary period by analyzing literature and drawing materials. For a time-series analysis, "Donggwoldo" and "Donggwoldohyeong" produced in the Joseon Dynasty, along with "Changdeokgung Plan Drawing" produced in modern and contemporary times, and aerial photographs were used. Drawings and photographs of different coordinate systems were transformed into one coordinate system in the geographic information system ArcGIS to compare changes in the movements of different periods. The results of the study are as follows. First, a total of 37 sections have been used since Japanese colonial era, of which 13 have been maintained, 14 have disappeared, and 10 have been newly established. Among the extinction sections, the road north of Neungheojeong Pavilion is considered to be an urgent place to connect the space to the garden and restore it to enjoy the scenery. In the new section, it seems necessary to establish a new alternative road or shorten the section for the connecting section between Daebodan and Okryucheon. Second, it was revealed that the biggest and most frequent changes to the road system in the garden were Japanese colonial era and renovations in the 1970s. It is worth noting the changes in the road since the 1970s, rather than Japanese colonial era, where it was difficult to manage the gardens independently. The access road to Okryucheon remained in its original shape until the 1990s, but it was renovated to its current shape due to misperception of the original shape. A project is needed to find out the cause of the change in this period and restore the damaged original shape. The biggest achievement of this study is that it revealed the changes in the garden path of Changdeokgung Palace in modern and contemporary times. The biggest achievement of this study is that it revealed the changes in the road of Changdeokgung Palace Rear Gardens in modern and contemporary times. However, there is a limitation that it has not been able to clearly present the location and shape that should be restored because it has not found data on landscaping plans or maintenance. In order to restore the road using the data revealed in this study, it seems necessary to consider realistic problems such as current space utilization, viewing system, disaster prevention and maintenance.

This Research analyzed with itinerary tracking : two of each other shopping sites were selected as research point. Analyzing the result, pedestrian path choice is affected by direction of escalator, visual information of the object, plain form of passage, presence and absence of companion and proportion of spatial knowledge from experience. The factors affecting pedestrian path choice are divided into two groups which are the effects from the environment, and personal characteristics.

본 연구는 휴대전화기의 문자메시지 전송UI가 사용자 만족도에 미치는 영향에 관한 것이다. 휴대전화기의 문자메시지 전송UI은 한글, 영문, 숫자, 특수문자, 기능키의 조합으로 이루어지고, 연구결과 사용자 만족도에 가장 많은 영향을 미치는 것은 한글 모음 입력임이 입증되었다. 가장 만족도가 높은 모음 입력방식은 점과 선을 이용하여 모음을 조합하는 방식이며, 짧은 동선과 그로 인한 입력시간 단축이 주요인이었다. 조사방법은 사용자 대상 설문조사를 사용하였고, 연구 방식은 문장을 입력할 때의 각 휴대전화 문자입력 UI의 동선과 버튼을 누르는 횟수를 비교 분석하여 결과를 도출하였다.

국립등대박물관은 1985년에 포항시 영일만에 있는 호미곶등대 옆에 건립되었다. 이후 몇 차례 확장을 했고, 2여년에 걸쳐 전시관을 신축하면서 유물관을 리모델링하고 2022년 7월 1일 재개관식을 개최했다.. 본 연구에서는 국립등대박물관의 핵심건물인 전시관의 상설전시공간의 현황을 조사하고 분석하여 국내 유일한 등대박물관으로의 역할과 발전방향을 고찰하고자 한다. 먼저 기존 상설전시실이 위치하던 유물관의 복잡한 동선체계를 개선하고 패널과 일반 모형 중심의 연출을 벗어나 이용객 지향적인 동선과 체험물을 활용했다. 앞으로도 전시공간 매치, 연출 및 그래픽 체계, 영상매체 등의 미디어를 활용해 관람객이 능동적으로 참여하는 공간을 구축해야 한다.

본 연구의 목적은 도시공원 조성시 물리.생태적 여건과 이용을 고려해 건강한 도시공원을 조성하는데 기초자료를 제공하는데 있다. 따라서 본 연구는 서울 서초구 양재시민의 숲(공원)을 대상으로 조성된 공원의 물리.생태적 여건과 이용의 관련성을 조사해 나타난 문제들을 GIS와 설문조사를 통해 분석했다. 조사항목으로 과거토지이용, 현토지이용(성토지역, 동선, 나지, 시설물), 식생(수고, 지하고, 최근색재지, 유실수, 불량식재지), 배수상태, 야간조명, 소음, 이용현황(이용밀도, 이용행태, 접근동선) 등이며 수고+소음, 지하고+이용밀도, 과거토지이용+배수불량, 이용행태+접근동선 등을 중첩해 문제점을 분석했다. 그 결과 본 공원은 식재, 배수, 소음, 이용(주차, 야간이용)등의 문제를 앉고 있으며 이에 대한 해결방안으로는 숲내 공지확보, 수로나 연못설치, 방음벽 설치, 주차장 확보 등이다. 설문조사에서 제안된 시설과 대안으로는 공원주변의 양재 화홰단지와 연계한 화단 및 화훼전시공원(43%), 현공원의 잠재력을 활용한 식물원 혹은 수목원(58%), 과일나무 공원(32%) 등을 들 수 있다. 결과적으로 이공원과 같이 규모가 큰 공원을 조성시에 위와 같은 문제들을 해결하기 위해서는 조성기간중 다양한 문제를 수용할 수 있는 유연한 단계별 계획이 필요할 것이다.

This study aims to investigate the effect that local government's information release range on Covid-19 patients' contact trace on consumer sentiment in the region. One hundred twenty-eight residents of Gangnam-gu and Seocho-gu participated in the study. The results showed that when ambiguity of information increased perceived anxiety on Covid-19 patients' contact trace, which in turn led lower intention to visit the commercial district near the Covid-19 patients' contact trace. Based on the findings, several suggestions was proposed for future research, including longitudinal studies covering even the "long-term" changes in consumer sentiment, the effect of implicit anxiety, and the behavioral difference between residence and non-residence.

The purpose of this study is to optimize the patient(examinee) flow in a health examination center via a simulation model and to improve operational efficiency. Two experimentation scenarios were implemented into the simulation model to determine which proposed scenario provides better improvement in terms of the following performance measures: LOS(Length of Stay), staff utilization, and occupancy level. The simulation results demonstrated that there was no significant difference in response results of two scenarios. Although the original motivation of this study was suggest optimal policy for a patient(examinee) flow, the insight into applying simulation in efficiently managing hospital operations is of more value. Simulation approach is a powerful technique that supports efficient decision-making compared to traditional healthcare management approach based on past experience, feelings, and intuition. Therefore, the proposed experimentation model has wide applicability in healthcare systems.

This study reports on the efficiency of cleaning enameled magnet wire using a sulfuric acid $H_2SO_4$ and removal of dissolved organic material using hydrogen peroxide $H_2O_2$ and nitric acid $HNO_3$ at $80^{\circ}C$. The method involves the addition of pure $H_2SO_4$ and $H_2O_2$ or $HNO_3$. Layers of enameled organic material were dissolved by 90% $H_2SO_4$ and the solution was maintained as 35% $H_2O_2$ or 60% $HNO_3$. $H_2O_2$ content in aqueous $H_2O_2$ was maintained as 8.8 : 1.0. An initial concentration of $H_2SO_4$ in dissolution conditions was accomplished within 15 min, with a stripping time of about 2 h. The concentrations of $H_2O_2$ and $HNO_3$ in the processing bath were relatively low, but sufficient enough to produce an effective amount of power in the bath for the removal of the enamel material. The cleaning effect of enameled organic material involves the dehydration by $H_2SO_4$ and the oxidation by $H_2O_2$ or $HNO_3$.
