박진균 대한영상의학회 1983 대한영상의학회지 Vol.19 No.1

Osteosarcoma is a malignant tumor arising from the undifferentiated fibrous tissue of bone and one of the most common primary malignant tumors of bone. The diagnosis of osteosarcoma is based on clinical, radiological and histopathological findings, but the majority of the patients with osteosarcoma can be diagnosed with a reasonable degree of confidence from the combination of the lesion site, age and radiological findings. This is a clinical and radiological observation of 40 cases of osteosarcoma which were experienced at Chonnam National University Hospital, Chosun University Hospital and Kwangju Christian Hospital from 1978 to 1981. The results were as follows : 1. The peak incidence was in the age group from 10 to 19 years in 21 cases (52.5%). 2. In sex distribution, male group showed slightly higher incidence than in female group with the ratio of 1.35 : 1. 3. The most commonly affected site was proximal tibia (35%). The lesion was found around the knee in 65% of the studies cases. 4. Increment of the level of serum alkaline phosphatase was observed in 25 cases (62.5%), and the average value of serum alkaline phosphature in these cases was 5.6 Bessay Lowry units. 5. Radiographically, osteoblastic type was 14 cases (35%), osteolytic type 9 cases (22.5%) and mixed type 17 cases (42.5%). 6. Cortical destruction was obsdrved in 30 cases (75%), and soft tissue mass shadow with calcification was observed in 34 cases (85%). 7. Solid periosteal reaction, sunburst periosteal reaction and Codman's triangle were observed in 35%, 57.5% and 22.5% respectively. 8. At the first visit, lung metastasis was found in 5 cases (12.5%) and inguinal lymphnode metastasis in 2 cases (5%).

Empirical estimation of human error probabilities based on the complexity of proceduralized tasks in an analog environment

박진균,김희은,장인석 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.6

The contribution of degraded human performance (e.g., human errors) is significant for the safety ofdiverse social-technical systems. Therefore, it is crucial to understand when and why the performance ofhuman operators could be degraded. In this study, the occurrence probability of human errors wasempirically estimated based on the complexity of proceduralized tasks. To this end, Logistic regressionanalysis was conducted to correlate TACOM (Task Complexity) scores with human errors collected fromthe full-scope training simulator of nuclear power plants equipped with analog devices (analog environment). As a result, it was observed that the occurrence probability of both errors of commission anderrors of omission can be soundly estimated by TACOM scores. Since the effect of diverse performanceinfluencing factors on the occurrence probabilities of human errors could be soundly distinguished byTACOM scores, it is also expected that TACOM scores can be used as a tool to explain when and why theperformance of human operators starts to be degraded

암진단 병력에 따른 주요 암 검진율

박진균,박현아 대한임상건강증진학회 2012 Korean Journal of Health Promotion Vol.12 No.2

Background: With the number of cancer survivors increasing, follow-up care to deal with problems related to their original cancer is needed. One of these is screening for a second primary cancer as cancer survivors are one of the high-risk groups for cancer occurrence. The purpose of this study was to assess the screening rates of major cancers in patients with a history of cancer in Korea. Methods: Our data were from the 4th Korea National Health and Nutrition Examination Survey. We narrowed the data to include 11,169 adults aged 40 and 80 years. Participants were grouped according to their history of cancer and the time since cancer diagnosis into no cancer group (no cancer diagnosis), cancer survivor group (cancer diagnosis ≥5 years ago), and cancer follow-up group (cancer diagnosis <5 years ago). We estimated the screening acceptance rates of major cancers according to the cancer history and assessed the relationships between them. Results: The cancer screening rates of stomach, breast, cervix, and colon were 42.4±4.9%, 45.5±5.6%, 42.1±6.4%,and 24.1±3.8% for the cancer survivor group and 45.6±5.2%, 61.9±6.2%, 48.8±7.0%, and 20.8±4.3% for the cancer follow-up group. A history of cancer diagnosis was not related to the acceptance rate of stomach and cervical cancer screening. Breast cancer screening (odd ratio [OR], 1.783; 95% confidence interval [CI], 1.044-3.048)increased only in the cancer follow-up group. At 5 years after a cancer diagnosis, only the screening rate for colon cancer (OR, 1.701; 95% CI, 1.119-2.588) persistently increased compared to individuals without a history of cancer. Conclusions: The screening for breast cancer was the only screening examination whose rate increased in the cancer follow-up group, with the significance disappearing in the cancer survivor group. Our results demonstrate that the screening rate for secondary cancers is below optimal in cancer patients in Korea. 연구배경: 암생존자의 증가와 함께 암생존자의 건강관리의 중요성이 대두되고 있다. 암생존자는 이차암의 위험도가 높은 집단으로 암검진의 필요성 또한 높다. 본 연구에서는 한국인 성인에서 암진단 병력에 따라 주요 암 검진율을 확인하고자 하였다. 방법: 제4기 국민건강영양조사의 면접조사에 참여한 40세부터 80세까지 성인 11,169명을 대상으로 하였다. 암진단력과 진단 시기를 확인하여 암미진단군, 암생존자군, 암추적관찰군으로 나누어 국립암센터의 암검진 가이드라인을 기준으로 주요 암 수검률을 예측하고, 암진단 병력과진단 후 시간이 수검률이 미치는 영향을 평가하였다. 결과: 암생존자군의 위암, 유방암, 자궁경부암, 대장암 수검률은 42.4±4.9%, 45.5±5.6%, 42.1±6.4%, 24.1±3.8%였다. 암추적관찰군에서는 각각 45.6±5.2%, 61.9±6.2%, 48.8±7.0%,20.8±4.3%였다. 암진단 여부는 진단 후 시간경과에 관계없이 위암과 자궁경부암 검사 수검률에 영향을 주지 않았고, 암추적관찰군에서는 유방암(odd ratio [OR], 1.783; 95%confidence interval [CI], 1.044-3.048)과 모든 암검진(OR,2.303; 95% CI, 1.541-3.442)에 대한 수검률이 증가하지만, 암생존자군에서는 대장암 검진수검률(OR 1.701; 95% CI,1.119-2.588)을 제외하고는 암미진단자와 다르지 않았다. 결론: 주요 암 검진 중 유방암 검진 수검률만이 암추적관찰군에서 증가하다가 암진단 후 5년이 경과한 후에는 암미진단군과 차이가 없어졌다. 한국인 암진단자에서 주요암 검진 수검률은 높지 않으며, 암진단 여부와 암검진 수검률은 진단 후 시간경과에 따라 다른 관련성을 보인다.

박진균,김택윤,송민,Park, Jinkyeun,Kim, Taekyoun,Song, Min 한국비블리아학회 2017 한국비블리아학회지 Vol.28 No.1

이 연구는 텍스트마이닝 기술을 이용한 개체계량학적 분석을 인문학 분야 인물 연구에 적용하기 위해 수행하였다. 연구 대상으로 한 인물은 작품뿐만 아니라 종교, 생애에 대해 많은 연구가 이루어진 윤동주를 선정하였다. 본 논문에서는 윤동주 관련 연구 1,076건을 수집하여 이중에서 초록 정보를 가지고 있었던 220건의 논문을 대상으로 LDA(Latent Dirichlet Allocation) 방식의 토픽모델링 분석을 수행하였으며, 참고문헌 정보를 추출할 수 있었던 121건의 논문을 대상으로 저자동시인용 분석을 통해 연구의 동향을 살펴보았다. 또한 초록에서 인명, 작품명의 개체를 추출하여 이들의 관계를 살펴보았다. 이 연구를 통해 윤동주에 관련한 연구 동향은 생애, 시, 실존의식, 비교문학, 번역문학, 종교적 신념에 대한 연구로 다양한 분야에 걸쳐 이루어졌다는 것을 데이터를 기반으로 보다 객관적으로 분석해 볼 수 있었으며, 윤동주와 함께 연구되는 다른 인물이 어떤 작품을 매개로 하여 연구되어 왔는지에 대해서도 알 수 있었다. 이러한 결과는 인문학 분야의 지적구조를 밝히는데 개체계량학적 방법이 유용함을 증명하는 한편 인문학연구의 새로운 시각적 접근을 제안했다는 데에 의의가 있다. This paper employs entitymetrics analysis on the research works of Dong-ju Yun. He was a Korean poet who was studied by many researchers on his works, religion and life. We collected 1,076 papers about Dong-ju Yun and conducted various approaches including co-author citation analysis, topic modeling analysis to identify the topic trend in the study of Dong-ju Yun. Also we extracted entities like person's name and literature's title from abstract to examine the relationship among them. The result of this paper enables us to objectively identify the topic trend and infer implicit relationships between key concept associated with Dong-ju Yun based on text data. Moreover, we observed sub-research topics such as life, poem, aesthetic existence, comparative literature, literary translation, and religious beliefs. This paper shows how entitymetrics can be utilized to study intellectual structures in the humanities.

A DATABASE FOR HUMAN PERFORMANCE UNDERSIMULATED EMERGENCIES OF NUCLEAR POWERPLANTS

박진균,정원대 한국원자력학회 2005 Nuclear Engineering and Technology Vol.37 No.5

Reliable human performance is a prerequisite in securing the safety of complicated process systems such as nuclear power plants. However, the amount of available knowledge that can explain why operators deviate from an expected performance level is so small because of the infrequency of real accidents. Therefore, in this study, a database that contains a set of useful information extracted from simulated emergencies was developed in order to provide important clues for understanding the change of operators’ performance under stressful conditions (i.e., real accidents). The database was developed under Microsoft WindowsTM environment using Microsoft Access 97TM and Microsoft Visual Basic 6.0TM. In the database, operators’ performance data obtained from the analysis of over 100 audio-visual records for simulated emergencies were stored using twenty kinds of distinctive data fields. A total of ten kinds of operators’ performance data are available from the developed database. Although it is still difficult to predict operators’ performance under stressful conditions based on the results of simulated emergencies, simulation studies remain the most feasible way to scrutinize performance. Accordingly, it is expected that the performance data of this study will provide a concrete foundation for understanding the change of operators’ performance in emergency situations.
