In the Seoul Metropolitan Area(SMA) photochemical air pollutants, nitrogenic compound and particulate matters have increased substantially due to mobile sources, power plants and so on. Therefore 'Special Act on Seoul Metropolitan Air Quality Improvement' was enacted on 2003 in order to improve air quality in the SMA. According to the Special Act, Central and local government have developed the state implementation plan(SIP) to reduce air pollutant emissions from various local sources. One of the key elements of the SIP development is the air quality modeling since modeling results can be used to establish emissions control strategies as well as to demonstrate attainment of air quality goals for ozone, particulate matter, and so on. Air quality modeling, therefore, can be usefully utilized to investigate the effects of government's efforts according to control strategies or measures. Using the air quality model, we can determine whether the implementation plan should be revised or not. A number of questions, however, has been raised concerning accuracy, consistency and transparency of modeling results because if we do not trust modeling results, all the measures dependent on modeling becomes in vain. So, without dealing with these questions, we can not guarantee the reliability and utilizability of air quality modeling results. In this study, we tried to establish standard methodology for air quality modeling in order to ensure consistency and transparency of modeling results used in the development and evaluation of national air policy. For this purpose, we established air quality modeling guideline to provide or recommend modeling procedures, vertical and horizontal domains, input data of meteorological and air quality modeling and so on.

Cardiac magnetic resonance (CMR) imaging is widely used in many areas of cardiovascular disease assessment. This is a practical, standard CMR protocol for beginners that is designed to be easy to follow and implement. This protocol guideline is based on previously reported CMR guidelines and includes sequence terminology used by vendors, essential MR physics, imaging planes, field strength considerations, MRI-conditional devices, drugs for stress tests, various CMR modules, and disease/symptom-based protocols based on a survey of cardiologists and various appropriate-use criteria. It will be of considerable help in planning and implementing tests. In addressing CMR usage and creating this protocol guideline, we particularly tried to include useful tips to overcome various practical issues and improve CMR imaging. We hope that this document will continue to standardize and simplify a patient-based approach to clinical CMR and contribute to the promotion of public health.

Objectives: This study was conducted to reflect the public's perspective when developing Korean Medicine (KM) Clinical Practice Guideline (CPG) for nausea and vomiting of pregnancy (NVP). Methods: 317 respondents who had experienced nausea and vomiting during current or past pregnancy completed the questionnaire online, and we analyzed their answers. Results: 1. 24% of all respondents had received KM treatment. The most common reason for choosing KM treatment was "it would be relatively safe for pregnant women and fetuses", and the reason for not choosing KM treatment was "they did not know much about it". 2. Respondents who had experienced KM treatment for NVP had felt the effects of KM treatment (79%), and chose herbal medicine as the most effective and preferred treatment. 3. 64.1% of respondents who had not experienced KM treatment for NVP preferred cooperative treatment with Western medicine. They answered that herbal medicine would be the most effective treatment, but preferred acupuncture. 4. The most important factor when treating NVP was "the safety of treatments". 59% of all respondents perceived KM treatment is safe for NVP. The treatments perceived as safest were herbal medicine and acupuncture, while the treatments with the least safety information were pharmacopuncture and electro-acupuncture. 5. Treatments that medical consumers were comprehensively interested in were acupuncture, KM treatment & Fluid, herbal medicine, moxibustion, and acupressure, in order. Conclusions: This study revealed the public's experience of using medical care, preference and perception of KM treatment for NVP. Therefore we would reflect the patients' clinical needs in the CPG.

Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.

지명은 일정한 지역의 명칭이다. 지명의 발생 요인은 인간의 한 지점이나 지역을 다른 지점 또는 지역과 구별하기 위한 데서 발생한다. 철도의 지명은 철도역명과 노선명 결정시 민감하게 반응한다. 서울을 비롯한 대도시권 도시철도의 노선은 번호체계로 통일되어 있으나, 간선철도의 노선은 다양한 성격으로 구분하여 노선명이 혼재하고 있다. 즉 기존선의 경우에는 역명이나 노선명에 혼란이 없으나, 신선건설의 경우에는 사업명 노선명에 혼란의 소지가 발생한다. 철도사업법 제4조(사업용철도노선의 고시)에서 국토해양부장관은 사업용 철도노선의 노선번호 노선명 기점 종점 중요경과지(정차역을 포함한다) 그 밖의 필요한 사항을 국토해양부령이 정하는 바에 의하여 지정 고시하도록 의무화하고 있다. 본고에서는 이의 결정기준과 체계화에 대하여 논의한다.

Nowadays, concerns have much more growing regarding indoor air quality (IAQ) on the public transportation including railway vehicles. Last year Korea Ministry of Environment (ME) set new guideline for public transportation. In this study several factors were analyzed which may affect comfortableness of railway passenger cabin, and we monitored IAQ parameters (PM10, CO, $CO_2$, VOCs, temperature and humidity) to investigate the present pollution in passenger cabin. In general, the railway air quality was satisfactory. The PM10 and $CO_2$ level on all passenger cabin were below the new guideline level 1 for PM10 $(200{\mu}g/m^3)\;and\;CO_2(2,000ppm)$. Clustering method was carried out to classify the air polluting pattern of the cabin. As a result, the pollutants could be classified to 4 clusters and the origin of pollution is soil, diesel exhaust gas, abrasion of rail and plume.
