  • 최근 ICT 및 IoT 제품의 활용 분야가 다양화 되면서 오픈소스 소프트웨어의 활용 분야가 컴퓨터, 스마트폰, IoT 디바이스 등 다양한 기기와 환경에서 활용되고 있다. 이처럼 오픈소스 소프트웨어의 활용분야가 다양해짐에 따라 오픈소스의 보안 취약점을 악용하는 불법적인 사례가 지속적으로 증가하고 있다. 이에 따라 다양한 시큐어 코딩을 위한 도구나 프로그램이 출시되고 활용되고 있지만 여전히 많은 취약점들이 발생하고 있다. 본 논문에서는 안전한 오픈 소스 소프트웨어 개발을 위해 오픈 소스의 취약점 분석 결과에 의한 이력과 패턴을 지속적으로 학습하여 신규 취약점 분석에 활용할 수 있는 방법을 제안한다. 본 연구를통해 취약점 이력 및 패턴 학습기반의 취약점 분석 시스템을 설계하였으며, 프로토타입으로 구현하여 실험을 통해 시스템의 성능을 평가하였다. 5개의 취약점 항목에 대해 평균 취약점 검출 시간은 최대 약 1.61sec가 단축되었으며, 평균 검출 정확도는 약 44%point가 향상된 것을 평가결과에서 확인할 수 있었다. 본 논문의 내용 및 결과는 소프트웨어 취약점 연구 분야에 대한 발전과 소프트웨어 개발자들의 취약점 분석을 통한 시큐어 코딩에 도움이 될 것을 기대한다.

  • 소프트웨어 공학 영역에 인공지능의 접목은 큰 화두 중 하나이다. 전 세계적으로 1) 인공지능을 통한 소프트웨어 공학, 2) 소프트웨어 공학을 통한 인공지능 두 가지 방향으로 활발히 연구되고 있다. 그 중 소프트웨어 공학에 인공지능을 접목하여 나쁜 코드 영역을 식별하고 해당 부분을 리팩토링하는 연구가 진행되고 있다. 해당 연구에서 인공지능이 나쁜 코드 요소의 패턴을 잘 학습하기 위해서는 학습하려는 나쁜 코드 요소가 라벨링 된 데이터셋이 필요하다. 문제는 데이터셋이 부족할뿐더러, 자체적으로 수집한 데이터셋의 정확도는 신뢰할 수 없다. 이를 해결하기 위해 코드 데이터 수집 시 전체 코드가 아닌 높은 복잡도를 가진 코드 모듈 영역을 대상으로만 나쁜 코드 데이터를 수집한다. 이후 수집한 데이터셋을 CodeBERT 모델의 전이 학습하여 코드 공통 취약점을 탐색하는 방법을 제안한다. 해당 데이터셋을 통해 CodeBERT 모델이 코드의 공통 취약점 패턴을 더 잘 학습할 수 있다. 이를 통해 전통적인 방법보다 인공지능 모델을 이용해 코드를 분석하고 공통 취약점 패턴을 더 정확하게 식별할 수 있을 것으로 기대한다.

  • Objectives: This study investigated the treatment response to Korean medicine of a paraneoplastic cerebellar degeneration (PCD) patient with dysarthria and weakness of distal extremity. Case presentation: A 53-year-old female diagnosed with PCD complained of dysarthria and weakness of distal extremity. During 32-day hospitalization, she was treated with Korean medicine, namely, herbal medicine (modified Gamiguibi-tang), acupuncture (15 minutes twice a day at CV23, HT7, LI4, LR3, ST36, SP6, GB20, TE17, PC6, GV20, Ex-HN1, GV24 etc.), moxibustion, and cupping, combined with Western medicine (prednisolone, azathioprine) and physical therapy. Post-treatment, the patient global assessment (PGA) score of dysarthria fell from 100 to 60; grasp power rose from 15 kg to 19 kg and 13 kg to 17 kg in the right and left hands, respectively; and the 5-level EQ-5D version (EQ-5D-5L), EQ visual analogue scale (EQ-VAS), and Beck depression inventory (BDI-II) scores changed from 10 to 8, 0 to 80, and 34 to 7 respectively. Follow-up visits continued for about a month after discharge, improvement in symptoms maintained, and there were no significant side effects. Conclusions: Given the lack of standard treatment for PCD, Korean medicine can be tried clinically for the treatment of PCD patients with dysarthria and weakness of distal extremity. However, further studies with control groups are needed.

  • By process of treatment for a case which diagnosed as spinal cord infarction and admitted from the 18th, April, 2000 to the 29th, July, 2000, the result are as foilows. Method and Results : In the earlier days of admission, this patient was diagnosed as damp-heat(濕熱) and was dosed with Cheongjo-tang. In medication, weakness in upper and lower limbs of the patient was improving. After diagnosed as Taeyangin, the patient was dosed with Ogapijangchuk-tang and punctured with Taeyangin Taegeuk-chim and Sagae-chim. As the result, Weakness in upper and lower limbs are improved remarkably. Conclusion : The prognosis of patients diagnosed spinal cord infarction is not so good. But, in the case of this patient, power and sense of four limbs improved remarkably through oriental medical treatment with rehabilitative therapy.

  • Nephrogenic systemic fibrosis (NSF) is a systemic disease that affects the skin and other tissues in patients with renal insufficiency and exposure to gadolinium-containing contrast. A 55-year-old woman with end-stage renal disease on hemodialysis was consulted for progressive general weakness. After she had undergone multiple MRIs with gadolinium-containing contrast media, muscle weakness and skin lesions were developed. Her skin and muscle biopsy specimens showed CD34+ fibroblast entrapping collagen bundles. There are few reports of NSF with myopathy.

  • Gak-gi-byung in Korean Medicine have many things in common with Beriberi disease, Guillain-Barre syndrome, Transverse myelitis and Cauda equina syndrome. Dong-Ui-Bo-Gam define Gak-gi-byung as syndrome that includes sudden lower limbs weakness, pain and edema. Gak-gi-byung start from the foregoing symptoms and could progress to general digestive, neurological or respiratory symptoms is found on many medical practitioners. In this case, we described a 60-years old man diagnosed as Gak-gi-byung in Korean Medicine. He complained Rt lower limb weakness, Rt Knee Clumsiness and limitation of his Rt knee & ankle motor. And his condition was improved through Korean Medical treatment such as acupuncture and herbal medicine like 'Chung-yul-sa-seup-tang' about 15 days.

  • Han-ok has a long history and cultural traditions. It has green and healthy and culture but high construction costs, thermal insulation performance of residential and vulnerable to fires and have a weakness for maintenance. However, modernized resident housing, Han-ok is required to improve in terms of environmental aspect due to its weakness for insulating and inconvenience for modem era. Also Han-Ok's building is criticized as a huge dependence on subjective building experiences. This is pointed to be the biggest problem, Han-ok has. Traditionally it does not have a scientific and specific manual for construction. In this research, process simulation was adopted to develop Han-Ok's environmental improvements. In terms of LCC (Life Cycle Cost) aspect, however, Han-Ok's environmental characteristics are examined to suggest an appropriate Han-Ok construction method. Also the result of this research would be utilized to base the information database for efficient constructing and its management in new Han-Ok constructing industry.

  • Objectives : The purpose of this study is to report a case of traditional Korean Medicine effect on a patient with rhabdomyolysis who appealed leg pain, numbness and weakness. Methods : A patient received traditional Korean Medicine including acupuncture, herbal medicine, moxibustion, and cupping therapy daily. We evaluated the clinical results by observing the patient's symptoms, NRS(Numerical Rating Scale), MMT(Manual Muscle Test) grade and DITI(Digital Infrared Thermal Imaging). Results : After traditional Korean Medicine, the patient's pain and numbness decreased from NRS 10 to 1~2 and weakness improved from Gr3- to Gr4. And CPK(creatine phosphokinase) numerical value decreased from 330(IU/L) to 164 and body heat status improved. Conclusions : Traditional Korean Medicine can be effective in reducing rhabdomyolysis patients' symptoms and changing examination numerical value. And further studies on traditional Korean Medicine of rhabdomyolysis should be carried out.

  • This case study describes the effect of Bojungikki-tang on chemotherapy-induced alopecia. Alopecia is a well-documented cause of distress to patients undergoing cancer treatment, but no approved pharmacological treatment exists for chemotherapy-induced hair loss. A 70-year-old female diagnosed with a cholangiocarcinoma and liver metastasis received chemotherapy, including gemcitabine and cisplatin, every three weeks. As a result of the continuous chemotherapy, she suffered various toxicity-related side effects, including bone marrow suppression, general weakness, nausea, peripheral numbness, and hair loss. Bojungikki-tang was initially administered to improve the patient's general weakness and fatigue. After three months of treatment, the patient's hair loss and general condition improved, and the color of the new hair was dark, despite the chemotherapy. The treatment did not improve other symptoms, such as bone marrow suppression and peripheral numbness. This case suggests that Bojungikki-tang could have a beneficial effect on chemotherapy-induced alopecia.

  • The purpose of this study is to analyze the strength and weakness of the intelligences appeared by the profile of the multiple intelligences of gifted children in mathematics. The subjects of this study were 80 students from D-Education Center for Gifted Children in Korea. Their multiple intelligences were measured by the self-scaling test of Korean-Multiple Intelligence Development Assessment Scale, in July 2006. The conclusions of this study are as follows: First, the strengths of multiple intelligences of the gifted children in mathematics are in logical-mathematical intelligence, intrapersonal intelligence and interpersonal intelligence. And, the weakness of multiple intelligences of the gifted in elementary mathematics is in bodily-kinesthetic intelligence. Second, formal educational curriculum of the gifted in elementary mathematics is required which can stimulate all kinds of intelligences.
