This study is to examine the public participation activities in the progress of the design competition, purposed to provide urban public spaces by the reuse of industrial heritages. Through the case studies of Berlin Tempelhof Parkland, Mapo Depot and Seoul Station 7017, following activities are common: citizen idea competition, forum, field trip, survey and winners exhibition. However, those activities are more closely organized to the competition process in Tempelhof Parkland, than other tow projects of Seoul Metropolitan Government. Also, it enables to clear and develop the public ideas more that those programs such as survey, citizen idea competition and field trip, are linked to each other in the case of Tempelhof Parkland. It could be achieved by the unified organization between competition preparation and public participation operation.

국가통계포털(2019)에 따르면, 우리나라 국공유지의 수량은 10,734,439필지와 33,395㎢로 국토면적의 33.2%를 점유하고 있다. 그동안 중앙정부 및 지방자치단체에서는 합병을 통하여 국공유지관리의 효율화를 도모하여 왔으나, 지적공부의 축척이 다르거나 서로 다른 유형의 지적공도에 국공유지가 등록되어 있는 경우에는 합병이 불가능하여 국공유지관리 효율화의 큰 장애요인으로 작용하고 있다. 이러한 문제점을 해소하기 위한 방안으로 측량을 수반하는 합병방법을 제시하여 실증하고 그 효과를 분석한 결과, 기존 방법의 54.9% 비용만을 지출함에도 불구하고 관리 대상 필지 수는 91.7%가 감소되었으며, 실태조사비용의 99.6%가 경감되는 것으로 확인되었다. 연접하여 군집화를 이루고 있는 국공유지에 대하여 합병측량을 실시하여 국공유지의 표시를 새로이 정하는 방식으로 합병정리하면 궁극적으로는 국공유지관리의 효율화에 기여할 수 있는 것으로 나타났다. 향후에도 지적측량을 기반으로 한 국공유지관리 관련 후속 연구가 다양하고 심층적으로 진행되기를 기대한다.

Objectives: We examined the prevalence of tobacco use and exposure to secondhand smoke among middle-school students in Korea using the Global Youth Tobacco Survey (GYTS) in 2013. Methods: The GYTS in Korea was conducted between July and August 2013 by the Korea Centers for Disease Control and Prevention. Data were collected using a self-administered anonymous questionnaire from a nationally representative sample of middle-school students aged 13-15 years in sampled classrooms. Results: The GYTS in Korea was completed by 4235 students aged 13-15 years in 43 middle schools. Approximately one in five of the students (17.8%) reported that they had tried cigarettes in the past, while 5.2% reported currently being cigarette smokers. Current cigarette smoking was higher in boys (7.5%) than in girls (2.6%). Of the students, 29.7% had been exposed to secondhand smoke at home, 47.4% inside enclosed public places, and 53.9% in outdoor public places. Of the current cigarette smokers, 25.7% bought their cigarettes from a store despite a law prohibiting this. Additionally, 58.0% of students noticed point-of-sale tobacco advertisements or promotions, 66.8% of current cigarette smokers wanted to stop smoking, and 70.9% of students had been taught about the dangers of tobacco use in school. Conclusions: These findings provide an opportunity to develop, implement, and evaluate a comprehensive tobacco control policy. The results suggest that youth have relatively easy access to cigarettes and are regularly exposed to secondhand smoke in public places, as well as to point-of-sale tobacco advertisements and promotions. Strict enforcement of the ban on tobacco sales to youth, expanding smoke-free areas, and advertising bans are needed to reduce tobacco use among youth.

The use of public Wi-Fi has increased in recent years with many people like to spend their time outside in malls or café shops which provide public Wi-Fi for their customers. However, since the public Wi-Fi can be accessed from any device the security of public Wi-Fi plays a big role to prevent the stealing of information by an attacker with methods and techniques such as WPA, WPA2 and WPA3. However, it is well known to the attackers that these methods are not difficult to get hacked by the attacker device to take the client precious information. Some researches were done in increasing the security of public Wi-Fi each with their own different technique or algorithm to provide more secure connection to the public Wi-Fi and prevent any unauthorized user to connect to avoid stealing the data of another legal user. Theses research paper are evaluated to learn which method excel in protecting the public Wi-Fi security by giving an analysis to the methods provided by the research paper with comparing the pros and cons of each algorithm. Moreover, the research displays that there are methods to actually provide security to the public Wi-Fi with each being very different in implementation.

Missing observations are common in medical research and health survey research. Several statistical methods to handle the missing data problem have been proposed. The EM algorithm (Expectation-Maximization algorithm) is one of the ways of efficiently handling the missing data problem based on sufficient statistics. In this paper, we developed statistical models and methods for survey data with multivariate missing observations. Especially, we adopted the EM algorithm to handle the multivariate missing observations. We assume that the multivariate observations follow a multivariate normal distribution, where the mean vector and the covariance matrix are primarily of interest. We applied the proposed statistical method to analyze data from a health survey. The data set we used came from a physician survey on Resource-Based Relative Value Scale(RBRVS). In addition to the EM algorithm, we applied the complete case analysis, which uses only completely observed cases, and the available case analysis, which utilizes all available information. The residual and normal probability plots were evaluated to access the assumption of normality. We found that the residual sum of squares from the EM algorithm was smaller than those of the complete-case and the available-case analyses.

Purpose: This study was conducted to assess the level of agreement among survey instruments used to study dementia and to determine the prevalence rate of suspected dementia using different instruments. Subjects and Methods: A total 171 subjects older than 65 in Gyeongju-si, Gyeongsangbuk-do, were surveyed from February to October 2003. The age, sex and educational level were examined through interview surveys, and cognitive function was evaluated using three survey instruments including MMSE-K, S-SDQ, and KDSQ. Results: The cognitive function scores obtained with the MMSE-K showed significant difference according to age. For sex and educational level significant differences were observed with all three survey instruments. The kappa index, the level of agreement between the questionnaires, was 0.302 between MMSE-K and S-SDQ, 0.401 between MMSE-K and KDSQ, and 0.762 between KDSQ and S-SDQ. The prevalence rate of suspected dementia based on the criteria suggested by MMSE-K, S-SDQ, and KDSQ was 27.5%, 15.2%, and 17.0% respectively. Conclusion: The results of this study suggest that caution is needed when comparing the measured cognitive function scores and analyzing the prevalence of dementia; this is because the prevalence of dementia and cognitive functions vary according to the questionnaires used.

Background: Topical corticosteroids (TCs) are available both as over-the-counter drugs and prescription medicines at pharmacies. Although they are generally safe drugs, inappropriate and excessive use could result in potential side effects. Thus, it is important to have appropriate knowledge regarding the use of TCs. We performed a cross-sectional survey to assess public knowledge and the potential misuse or overuse of TCs. Methods: A cross-sectional and nationwide online survey was conducted among participants who were aware of TCs. The survey items included sources of information, indications, potential side effects, and methods of application of TCs. A comparative analysis was conducted between those with (TC users) and without (TC non-users) an experience of using TCs. Results: Among 3,000 participants, 74.4% were TC users. The mass media was the most common information source of TCs, and only one-third of the surveyed people relied on pharmacists or doctors for information. Regarding indications and application methods, incorrect answer rate was high in some items, but respondents showed adequate knowledge. However, awareness of the safety of TCs was low. Overall, the TC users showed a higher knowledge of TCs than TC non-users. Conclusions: Public knowledge of the use of TCs appears to be appropriate. However, we found potential misuse or overuse of some items and a lack of awareness of the side effects concerning TCs. Thus, healthcare professionals' significant role is required.

Purpose: The number of severely ill patients requiring post-acute care has been increasing. Careful discharge planning minimizes unplanned emergency room visits and readmissions. This study aimed to survey the knowledge, experience, confidence, and obstacles faced by medical residents and fellows regarding the discharge process of severely ill patients. Methods: A survey consisting of 27 questions was sent electronically to residents and fellows who had experience in discharging severely ill patients from a tertiary hospital in Korea. The survey was conducted over a two-week period from September 29, 2022. Results: A total of 98 residents and fellows responded to the survey. Of these, 94% experienced difficulties related to the discharge process. The main obstacle was changes in the patient's condition during discharge planning (92.3%). Although 95% of the respondents acknowledged the need for providing discharge information, only 53.1% of the residents and fellows practiced this. Only 42.9% of the respondents and 20.4% of residents and fellows explained local community healthcare and welfare resources to patients because of a lack of relevant knowledge (69.7%) and feeling no responsibility to explain (40.4%). Conclusion: This study revealed that residents and fellows experienced difficulties in devising discharge plans and providing post-acute care related information, despite recognizing the importance of these. These gaps result from the lack of a discharge planning curriculum regarding critically ill patients and appropriate training in the discharge process. This suggests that an integrated discharge planning curriculum should be developed and adopted in residents' training programs for the differentiated treatment of critically ill patients.

Background: Currently establishment of public pharmaceutical companies became an issue for securing stable supply of national essential drugs in order to respond appropriately to national public health crisis. Pharmacy students as future pharmacists need to be interested in drug related issues under the discussion in our society. This study aimed to investigate perceptions of pharmacy students on the national drug supply strategy through public pharmaceutical companies. Methods: A 20-items questionnaire designed for this study was used. Pharmacy students nationwide were enrolled in July 2017. They responded to questions through on-line survey program. Data were analyzed descriptively. Results: 160 students from 26 pharmacy schools participated. 5th and 6th grade students accounted for two-thirds, and one third aspired future jobs in pharmaceutical industry. Among responders, 71.3% was unaware of current national essential drugs, 52.5% did not know the Rare and Essential Drug Center, and 91.9% was unaware of the legislation on the supply and management of essential drugs. 82.5% favored the establishment of public pharmaceutical companies. 80.6% agreed that government should intervene in pharmaceutical market for ensuring drug accessibilities, 73.8% agreed that public pharmaceutical companies make possible to reach a goal of stable supply of pharmaceuticals, and 85.1% agreed that active compulsory license by public pharmaceutical companies is necessary. Conclusion: We found that pharmacy students recognized the need for governmental control to achieve social values of pharmaceuticals. More attention and participation of the pharmacy students as well as pharmacists in the process of national debate on public pharmaceutical companies are expected.

Objectives: The study investigated the association between indoor air pollution (IAP) and risk factors for acute respiratory infection (ARI) symptoms in children under 5 years of age. Methods: A cross-sectional study was conducted using data derived from Indonesia Demographic and Health Survey in 2017. Binary logistic regression modeling was employed to examine each predictor variable associated with ARI among children under 5 years of age in Indonesia. Results: The study included a total of 4936 households with children. Among children under 5 years old, 7.2% reported ARI symptoms. The presence of ARI symptoms was significantly associated with the type of residence, wealth index, and father's smoking frequency, which were considered the sample's socio-demographic characteristics. In the final model, living in rural areas, having a high wealth index, the father's smoking frequency, and a low education level were all linked to ARI symptoms. Conclusions: The results revealed that households in rural areas had a substantially higher level of reported ARI symptoms among children under 5 years old. Furthermore, the father's smoking frequency and low education level were associated with ARI symptoms.
