선택적 집중과 총량적 경제논리에 기반한 거점도시 중심의 균형발전정책은 도시화를 촉진하며 인구유출, 고령화, 소득감소 등 농촌지역의 경쟁력을 약화시키는 요인으로 작용하였다. 이를 해소하기 위해 중앙정부 차원의 다양한 지원과 노력이 이어지고 있으나 하향식(Top-Down)에 의한 지원효과는 저조한 실정이다. 최근 농촌지역은 지역성과 정체성을 고려한 차별화된 맞춤형 정책의 요구가 높아지고 있으며, 이를 위한 지역 맞춤형 진단기술의 필요성이 제기되고 있다. 본 연구에서는 농촌지역의 종합적 진단을 위해 선행연구에서 제시된 다양한 지표를 검토하고, 농촌지역의 특성을 확인할 수 있는 맞춤형 진단지표의 발굴을 연구의 목표로 설정하였다. 이를 위해, 농촌진단 관련 지표군(POOL)을 구축하고, 전문가 설문조사와 요인분석을 통해 우리나라 농촌지역의 특성에 맞는 진단지표를 선정하였다. 본 최근 정부정책의 화두인 '맞춤형 적정기술'의 적용성을 높이기 위한 농촌지역에 대한 진단도구로서 의미를 지닌다.

Regional agricultural research has been activated since the mid of 1980s by the government`s integrated rural development policy based on regional unit(kun). It is called upon to meet the challenges which the agriculture confronts in the general evolution of the society. However, regretfully it seems this new approach has not succeeded in developing its own theoretical tools for the diagnostic analysis of regional agriculture. So, this study would introduce the french agrarian system theory which has been developed by the interdisciplinary research groups of the France`s National Agricultural Research Institute, which is now filtering outside the country to various parts of the world. It attempts also to apply the above theory to analyse one of agricultural regions located in the province Cheollabukdo, so as to see its theoretical pertinency and efficiency in the regional agricultural development planning which constitute the main part of the regional planning.

Medical infrared imaging is obtained by measuring the self-emitted infrared radiance from the human body. Infrared emission is related to surface temperature and temperature is one of the most important physiological parameters related to health. Though recent applications such as security identification and oriental medicine have provided new fields of biomedical applications, infrared thermography has had ups and downs in its usages in cancer detection. Some of the main difficulties include finding proper applications and efficient diagnostic algorithms. In this study, infrared thermal imaging was used to detect regional metastasis of breast cancer. Our measurements were done for 110 women. From 63 individuals of a Healthy Group and a Benign Breast Disease Group, we developed algorithms for differentiating malignant regional metastasis based on temperature difference and asymmetry of temperature distribution. Testing with 47 cancer patients, we achieved a positive predictive value of $87.5\%$ and a negative predictive value of $95.6\%$. The results were better than for mammogram examination. A proper analysis of infrared imaging proved to be a highly informative and sensitive method for differentiating regional cancer metastasis from normal regions.

This study was conducted to review data utilization plans and suggest solutions based on the need for tools that can objectively diagnose problems in rural areas. The study extracted items through prior research and was carried out as a process of reviewing data capable of constructing spatial data. The results performed in the above manner are as follows. First, prior research and expert surveys were conducted to select diagnostic items to derive details of a total of three items that should be considered for rural space plans such as regional revitalization and regeneration using regional characteristics such as environment, society, and culture. Second, as a result of listing data available for regional diagnosis, 6 types of environment, 15 types of society, and 18 types of culture were selected out of a total of 529. Finally, it was suggested to establish a national standard spatial unit by grasping the limitations of public data such as omission of spatial data and accuracy. This study is significant in that it presented implications for data utilization as well as selection of items for rural diagnosis and reviewed data utilization based on rural specialized districts of "The Act on Support for Restructuring and Regeneration of Rural Spaces" to be implemented in 2024. This is considered to be valuable as a study for sustainable rural diagnosis if processes such as spatial data construction and weight setting are carried out in the future.

Mastoid lymph node inflammation is a rare entity. Pathological conditions in the vicinity of the mastoid processes can be challenging for maxillofacial head-neck surgeons to address. We report a case of suppurative mastoid lymphadenitis in an 18-year-old Caucasian male. To our knowledge, there are no publications that highlight the clinical, ultrasonographic, intra-, and postoperative data for any pathologic process that presented as mastoiditis.

This study was carried out to improve service efficiency and to cope with a emergency situation in emergency radiography, through analysis of the radiographic distribution and literature cited about emergency care. Data collection of radiographic distribution was surveyed for 761 emergency outpatients who visit during JAN, 1994 at ER of the general hospital in Pusan city. The results is as follows: Emergency radiography rate of simple radiography was 61.1 %, special radiography 2.5 %, CT 12.6 %, and ultrasonography 6.7 %. In simple radiography rate, a high rate was distributed on male(63.6 %), thoracicsurgery part(90.0%), admission patient(74.9 %), and long stayed patient at ER. In special raiography rate, a high rate was observed in urologic part(28.6%), and in CT rate, observed neurosurgery part(49.2 %) and neurologic part(36.7%). Ultrasonography rate was high for female(8.8 %) and internal medicine part(15.9 %). There are distributed regional radiography rate in radiographic type that chest(55.3 %) is high in the simple radiography, urinary system(1.2%) in the special study, and brain(40.0 %) in the CT. Regional radiography rate according to diagnostic department also was showed highly for head(64.6%) in neurosurgery, chest(90.0%) in thoracic-surgery, abdomen(58.0%) in general-surgery, spine (40.0% ) in neuro-surgery, and pelvis(15.9%), upper extrimity(20.5%), and lower extrimity(31.8%) in orthopedic-surgery each. Mean radiographic case number per patient of simple radiography was sinificant on sex, age, transfer relation in both total and radiographic patients(p<0.05). Mean radiographic case number was highly distributed on male(2.2 case number) in sex, on thirties(2.7) in age, transfered patient(2.7) in patient type, and on neurosurgery(3.4) in diagnostic charged part. Total radiographic case number in regional part was highly distributed on chest(499 case number). Considering the above results, emergency radiographer should take care of the elder patient in emergency radiography and get hold of injury mechanism to decrease possible secondary injury during radiography. Because of high radiography rate of urinary system in special study, radiographer should know well about dealing with contrastmedia administration and related instrument. All radiographer who take charge emergency patient should cope with a emergency situation during radiography, Because head trauma patients is very important in patient care, especilly in CT at night, charged doctor should be always silted with CT room and monitoring-patient. Radiography was reqested by many diagnostic department in ER. Considering that rate of simple radiography is high, special room for emergency radiography should be established in ER area, and the radiographer of this room should be stationed radiologic technician who is career and can implement emergency patient care.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has necessitated a redistribution of resources to meet hospitals' service needs. This study investigated the impact of COVID-19 on a regional trauma center in South Korea. Methods: We retrospectively reviewed cases of polytrauma at a single regional trauma center in South Korea between January 20 and September 30, 2020 (the COVID-19 period) and compared them to cases reported during the same time frame (January 20 to September 30) between 2016 and 2019 (the pre-COVID-19 period). The primary outcome was in-hospital mortality, and secondary outcomes included the number of daily admissions, hospital length of stay (LOS), and intensive care unit (ICU) LOS. Results: The mean number of daily admissions decreased by 15% during the COVID-19 period (4.0±2.0 vs. 4.7±2.2, p=0.010). There was no difference in mechanisms of injury between the two periods. For patients admitted during the COVID-19 period, the hospital LOS was significantly shorter (10 days [interquartile range (IQR) 4-19 days] vs. 16 days [IQR 8-28 days], p<0.001); however, no significant differences in ICU LOS and mortality were found. Conclusions: The observations at Regional Trauma Center, Pusan National University Hospital corroborate anecdotal reports that there has been a decline in the number of patients admitted to hospitals during the COVID-19 period. In addition, patients admitted during the COVID-19 pandemic had a significantly shorter hospital LOS than those admitted before the COVID-19 pandemic. These preliminary data warrant validation in larger, multi-center studies.

Myocardial perfusion imaging has been increasingly used to provide prognostic data and guidance on the choice of appropriate management of patients with known or suspected coronary artery disease. The electrocardiogram gated myocardial SPECT program is corning into wide use with an advent of $^{99m}Tc-labeled$ tracers and an improvement of SPECT machines. The gated technique permits measurement of important cardiac prognostic indicators without any further discomforts or radiation burden in patients underwent standard myocardial perfusion SPECT. In addition, gated study significantly improves diagnostic yield by reducing the number of borderline interpretations and could find myocardial stunning and viable myocardium. Gated single photon emission computed tomography (SPECT) imaging allows the automated calculation of end-diastolic volume, end-systolic volume, ejection fraction, myocardial mass and the assessment of regional wall motion and thickening, and it have dramatically improved assessment of coronary artery disease in routine nuclear practice. This allows the simultaneous assessment of both perfusion and function within the same acquisition, and serves as a cost-effective technique for providing more diagnostic data with fewer diagnostic tests. Because the diagnostic and prognostic power derived from knowledge of left ventricular function can be added to that provided by assessing myocardial perfusion, gated SPECT imaging has rapidly gained widespread acceptance and is now used on a routine clinical basis in a growing number of laboratories, including South Korea. The gated SPECT technique for measurement of left ventricular parameters has been validated against a variety of well established techniques. In this work, overview of gated myocardial perfusion SPECT focus on functional parameters is presented.

Kudoa septempunctata, a myxozoan parasite, usually presents without any signs and primarily infects adult fish. The invasive diagnostic methods, such as tissue biopsy, can identify pathogens, but cause economic losses because they require killing the fish. In this study, we conducted a monitoring of four fish farms located on Jeju Island, to investigate the potential for non-invasive diagnosis of K. septempunctata using hyperspectral cameras. It provides spectral information from R000_B000_G000 to R255_B255_G255 for a total of 3,282 olive flounder (Paralichthys olivaceus). Each object is imaged with 2,000 data points, allowing comprehensive spectral analysis by comparing images obtained from negative control objects to positive control objects. Noticeable differences were observed in the brightness or pallor of the positive control images. This suggests the potential utility of hyperspectral imaging as a non-invasive diagnostic tool for detecting K. septempunctata infections in fish populations.
