Through a wide variety of disciplines, practices on data access and re-use have been increased recently. In fact, there has been an emerging phenomenon that researchers tend to use the data sets produced by other researchers and give scholarly credit as citation. With respect to this practice, in 2012, Thomson Reuters launched Data Citation Index (DCI). With the DCI, citation to research data published by researchers are collected and analyzed in a similar way for citation to journal articles. The purpose of this study is to identify the characteristics and intellectual structure of sociology field based on research data, which is one of actively data-citing fields. To accomplish this purpose, two data sets were collected and analyzed. First, from DCI, a total of 8,365 data were collected in the field of sociology. Second, a total of 12,132 data were collected from Web of Science with a topic search with 'Sociology'. As a result of the co-word analysis of author provided-keywords for both data sets, the intellectual structure of research data-based sociology was composed of two areas and 15 clusters and that of article-based sociology was composed with three areas and 17 clusters. More importantly, medical science area was found to be actively studied in research data-based sociology and public health and psychology are identified to be central areas from data citation.

지속적으로 증가 하고 있는 악성 종양 발병률의 증가, 생존률의 향상, 조기발견의 증가 등이 암 기왕자의 보험 수요 상승을 가져오고 있으며, 보험시장에서 더 이상 암 기왕자를 도외시하기 어렵게 만들고 있다. 그러나, 현재 국내에서는 암 기왕자를 인수할 수 있는 상품과 언더라이팅 인수 기법이 부족한 실정이다. 본 논문은 이러한 상황 하에서 기존에 거절체로 인식되었던 암 기왕자의 적극적인 인수를 위해 악성종양에 대한 보험 의학적인 고찰과 사망률, 위험도에 대해 분석하고, 국내에서 암 기왕자의 보험 인수 시 문제점과 그 해결방안을 모색해 보았다. 종양은 종양세포의 성장과 확산의 정도를 나타내는 병기와 조직학적 등급에 의해 그 예후와 경과가 예측 가능하며, 이 병기를 표준화하려는 국제적 시도로 1977년 American Joint Committee on Cancer(AJCC)는 TNM system 을 제시하였다. 병기를 기초로 치료의 결정도 함께 이루어지는데, 주요 치료법을 수술, 방사선치료, 항암치료, 면역요법이 있다. 이러한 치료법들은 후기 부작용을 일으키거나 이차성 암(Secondary malignant neoplasm)의 원인이 되기도 한다. 병기에 따른 암환자의 사망률을 살펴 보면, 암은 일정시기 동안 사망률이 급격히 증가하다가 이후에 점차 사망률이 감소하고, 그 이후에는 사망률에 영향을 미치지 않는다. 이러한 사망률 변화의 특성은 암 기왕자에게 평준식 정액 할증법(Per mille flat extra)의 적용이 적절함을 보여준다. 그러나, 현재 국내에서는 악성 종양 기왕자를 위한 상품이 전무한 상태이며, 암의 병리적 병기와 치료에 관련된 정보를 얻을 수 있는 도구도 부족하고, 명확한 인수 기법이 없다. 또한, 자체의 경험통계의 부족으로 위험에 대한 부담감이 큰 것이 현실이다. 하지만, 병기에 따른 사망률의 변화에서도 알 수 있듯이 평준식 정액 할증법의 도입이나, 악성종양의 병기(Stage)별 정액 할증률을 삭감법으로 전환하는 기준을 개발한다면, 종신보험은 충분히 인수가 가능하다. 또한, CI 보험도 암에 대한 부담보를 하는 선진사의 인수 기법을 도입하거나, 암 기왕자만을 위한 CI 상품을 개발하는 등 새로운 인수 기법을 모색한다면, 암기왕자 인수의 폭은 넓어질 것이다. 이와 같은 노력과 함께, 언더라이팅의 정보 획득을 위한 암 기왕자만의 고지서를 개발하고, 전문 언더라이터의 양성을 위한 노력을 게을리 하지 않는다면, 암기왕자를 적극적으로 인수할 수 있을 것이다. 앞으로 국내 보험사가 위와 같은 노력을 지속적으로 해 나가고, 비교적 예후와 경과가 양호한 0기와 1기 암 기왕자부터 단계적으로 종신보험의 인수를 시도한다면, 비교적 안전하게 경험치를 축적할 수 있을 것이다. 뿐만 아니라 국내 보험업계는 새로운 시장의 확보와 보험에 대한 대외 이미지 개선이라는 효과도 함께 얻게 될 것이다.

This study was conducted to compare the effectiveness of the newly developed electrode pad of ECG with that of a conventional method. To accomplish this, participants who performed both methods on a 46 year old male model were queried and their satisfaction, time, and accuracy were measured by a specialist from 01/06/2018 to 15/06/2018. In the conventional method, a newly developed single pad employing a 12-lead ECG and SIM-Tree was employed. There were 104 total participants in this study (44% medical members). Evaluation of the total procedure time revealed that SIM (mean 65.39 seconds) was more rapid than C (mean 94.38 seconds) (p<0.05). When we evaluated the response after all process, satisfaction with SIM (mean 97.69 seconds) was greater than that with C (mean 68.5 seconds) (p<0.05). Moreover, the intra-class correlation coefficient (ICC) was 0.959 and accuracy was very high (p<0.05). In conclusion, the SIM-Tree was very effective based on procedure time, satisfaction and accuracy when compared with conventional methods.

System performances in terms of image quality between an amorphous silicon DR system and a conventional film-screen system were evaluated. Various aspects of image quality MTF (modulation transfer function), NPS (noise power spectrum), SNR(signal-to-noise ratio) and contrast were measured and calculated. The MTF of the DR system was comparable to the film-screen systems. The noise was mainly dominated by the quantum mottle in both systems and the electronic noise was found in the DR system. The contrast of the DR system was better than the film-screen systems by virtue of high sensitivity and image processing. Compared to the film-screen systems in general radiography, the DR system had similar resolution and showed better contrast with the same exposure condition after contrast manipulation. The results of this study provide some useful information about the performance of the DR system in connection with medical applications.

Recently, lots of internet service companies provide on-line health diagnosis systems. But general persons not having expert knowledge are difficult to use, because most of the health diagnosis systems present prescriptions or dietetic treatments for diseases based on western medicine. In this paper, a self health diagnosis system of oriental medicine coinciding with physical characteristics of Korean using fuzzy ART algorithm, is proposed. In the proposed system, three high rank of diseases having high similarity values are derived by comparing symptoms presented by a user with learned symptoms of specific diseases based on treatment records using neural networks. And also the proposed system shows overall symptoms and folk remedies for the three high rank of diseases. Database on diseases and symptoms is built by several oriental medicine books and then verified by a medical specialist of oriental medicine. The proposed self health diagnosis system of oriental medicine showed better performance than conventional health diagnosis systems by means of learning diseases and symptoms using treatment records.

Recently, digital image processing is being applied in various areas of broadcasting, communication, computer graphic and medical science. But, degradation of images occurs in the process of digital image acquisition, processing and transmission. Therefore, in order to remove the mixed noise, this paper suggested the image restoration algorithm to process salt and pepper noise with weighted filters according to 4 direction pixel changes after judging the noise and to process AWGN with weighted filters which have individually different characteristics. Regarding the processed results by applying Boat images which were corrupted by salt and pepper noise(P=40%), suggested algorithm showed the improvement by 1.33[dB], 1.41[dB], 0.51[dB] respectively compared with the existing CWMF, AWMF, MMF.

Objectives : This study was designed to investigate datas related to panic attack and treatment in emergency room of panic disorder patients who visited emergency room for panic attack. Methods : A retrospective analysis of medical records was conducted on 92 patients with panic disorder who visited Chungju Konkuk university hospital emergency department due to panic attack and had bodily symptoms from 1st January 2010 to 31th December 2019. In addition to demographic characteristics and comorbid disorders, triggering stressors and alcohol consumption were corrected as pre-panic attack datas, bodily symptoms at the time of panic attack were corrected as datas during attack, electrocardiogram trial, consultation with psychiatrist, admission and information of used psychotropic drugs were corrected as post-attack data. Depending on size of data, Chi-square test or Fisher's exact test was used. Collected data was analyzed using R 4.03. Results : Cardiovascular disease was accompanied by 5.4% and depressive disorder was the most common coexisting mental disorder. Among triggering stressors, economic problem/work-related stress was significantly higher in men than women (𝛘²=4.322, p<0.005). The most common physical symptom during attack was circulatory (65.2%), followed by respiratory (57.6%), numbness-paralysis (33.7%), dizziness (19.6%), gastro-intestinal (14.1%) and autonomic symptom (12.0%). Electrocardiogram was taken at higher rate when patients complained circulatory symptom (𝛘²=8.46, p<0.005). The psychotropic drug most commonly used in emergency room was lorazepam, used in 92.1%. Conclusions : The most common bodily symptom during panic attack was circulatory symptom and the most common triggering stressor in men was economic problem/work-related stress. The most commonly used psychotropic for panic attack was lorazepam.

Objectives : There may be methodological differences between pencil-and-paper and web-based questionnaires. But there are few reports about influences of that methodological differences. The Aim of this study is investigation of the differences in temperament characteristics in subjects who answered internet addiction questionnaires. Methods : We compare the characteristics between two groups. Four hundred thirty participants(189 males, 241 females) answered the online and offline questionnaires. We controlled sexes, addiction scores and psychiatric treatment histories using general linear model of MANCOVA. Results : There were statistically significant differences in temperament characteristics between two groups. Harm avoidance(HA) and novelty seeking(NS) scores were significantly higher in on-line group than off-line group. Reward dependence(RD) scores were significantly lower in on-line group than off-line group. Conclusion : This study suggested significant differences of temperament characteristics between on-line and off-line subjects. And there have been many studies on equivalence of on-line and off-line survey methods. Further studies on the difference are expected for the understanding of this results.

This study investigates the characteristics of patients hospitalized at a convalescent hospital, by considering patient groups based on their medical record information. It further analyzes and correlates the factors, thus providing basic data required to improve the patient classification system at convalescent hospitals. The data includes total information of 213 medical records of patients discharged from a convalescent hospital in the Jeonbuk region during a period of one year, from January to December 2016. The study examines and correlates the days of hospitalization and the number of diseases, revealing a positive correlation having a correlation coefficient, thereby indicating that infliction with a greater number of diseases results in longer hospitalization. Based on these findings, the study raises the need to revise and supplement items on the patient assessment report to help determine the patient groups and identify medical efforts to be actually provided to patients. In addition, a proper care service system for each patient group based on their respective problems that are intensively managed according to the patient groups will be an essential element in the efficient management of convalescent hospitals. Furthermore, an important task addressed will be in managing the health of the elderly population at the national level.
