  • Dr. Haruyuki Ogino, a member of the Japan Health Physics Society (JHPS), was awarded the 2021 Bo Lindell Medal by the International Commission on Radiological Protection (ICRP). To commemorate this, the "Joint JHPS-KARP-ARPS program for young radiation protection (RP) scientists to discuss the future of RP" was organized via a web meeting system. First, Dr. Ogino gave a lecture, and then young researchers selected from each academic society made presentations on the future of RP. After the presentations by the three researchers, a free talk was held-young researcher groups of each country being active is a great opportunity to collaborate and exchange information. It was emphasized that the low awareness of knowledge related to radiation has been common to all of the participating countries. Thus, it is necessary to utilize communication via web technology, as done for this program, effectively. One of the biggest advantages for Asia and Oceania is that we do not have a significant time difference. The round-table discussion was concluded by expressing the hope of active exchange and development of young researchers in the future.

  • To analyze reception dishes of Choson Dynasty, studied historic book ‘Youngjeob Dogam Younhyangsek Euigwae’ (1609, 1634, 1643 year) described feast dishes for Chinese envoy in Choson Dynasty. The results obtained from this study are as follows. 1. The feast dishes consisted of the first main feast dishes (下馬宴, 上馬宴), the second main feast dishes (翌日宴, 請宴 and etc) and the third main feast dishes (別茶啖). 2. 下馬宴, 上馬宴 were arranged in four kinds of tale, the first one called the main table, the second the right side table, the third the left side table, the fourth the confronting side table. Dishes of main table were oil and honey pastry and fruits. Dishes of the second table and the third table were oil and honey pastry, and small cake made of honey and rice with patterns pressed in it. Dishes of the fourth table were cooked vegetable, dried slices of meat seasoned with spices, cooked meat, and fried fish. In feast, Chinese envoy drank 11 cups (1609 year) and 5 cups (1634 year) of liquor. At the first cup they abalones soup, others in a small round table (初味), a small boiled meet (小膳) and a large boiled meat (大膳), at a second cup eat (二味), at third cup eat (三味)..., at eleventh cup, they eat (十一味) and fruits.

  • 식사하는 철학자 문제는 5명의 철학자(프로세서)들이 원형 탁자에 둘러 앉아 함께 스파게티(또는 국수) 식사를 하는데 있어 자신의 양쪽에 있는 젓가락(자원) 한 쌍(2개)을 모두 가져야만 식사가 가능한 경우로 모든 철학자가 우측의 젓가락 1개씩 모두 가진 경우 아무도 식사를 못하는 교착상태(deadlock)를 해결하는 문제이다. 교착상태는 병행 시스템(concurrent system)에서 빈번히 발생하는 문제로 현행 운영체제(OS)에서는 이를 예방하는 방법은 채택되지 않고 있다. 본 논문은 2≤n≤∞의 모든 프로세서들이 다중 병행(parallel concurrency)처리 능력을 갖고 있는 OS에서 교착상태를 전혀 유발하지 않는 묘책을 제안한다. 제안된 방법은 ⌊n/2⌋개의 홀수 프로세서들이 그룹을 형성하여 동시에 수행하는 방법으로 실행이 종료되면 다음 프로세서로 우측 이동(shift right)시키는 그룹 라운드-로빈 방법이다. 제안된 방법은 1-라운드의 모든 프로세서를 실행시키려면 짝수 프로세서인 경우 2회, 홀수 프로세서는 3회를 수행하면 되고, n회를 수행하면 짝수 프로세서인 경우는 n/2회, 홀수 프로세서는 (n-1)/2회를 수행하는 방식이다.

  • Background: The incidence rate of thyroid cancer has been increasing worldwide in recent years, and it is also the most prevalent cancer when it comes to the number of patients among Korean women. With it, ultrasonographic screening test has also become very common. However, there is still controversy over the performance of this screening test. Therefore, the National Evidence-based Healthcare Collaborating Agency (NECA) organized a Round-table Conference on the issues regarding ultrasonographic screening for thyroid cancer in Korea. The objective of the conference was mainly about delivering worthwhile information reflecting social value for the current situation, which was based on evidence surrounding thyroid cancer screening that relevant experts investigated and agreed on. The significance of this Round-table Conference lies in the fact that we reviewed the current evidence, and we were able to discuss the social value and future direction for ultrasonographic screening in Korea.

  • The dynamic characterization of a three-story auxiliary building in a nuclear power plant (NPP) constructed with a monolithic reinforced concrete shear wall is investigated in this study. The shear wall is subjected to a joint-research, round-robin analysis organized by the Korea Atomic Energy Research Institute, South Korea, to predict seismic responses of that auxiliary building in NPP through a shake table test. Five different intensity measures of the base excitation are applied to the shaking table test to get the acceleration responses from the different building locations for one horizontal direction (front-back). Simultaneously to understand the global damage scenario of the structure, a frequency search test is conducted after each excitation. The primary motivation of this study is to develop a nonlinear numerical model considering the multi-layered shell element and compare it with the test result to validate through the modal parameter identification and floor responses. In addition, the acceleration amplification factor is evaluated to judge the dynamic behavior of the shear wall with the existing standard, thus providing theoretical support for engineering practice.

  • LOSA is spreading rapidly over the world to improve safety of the airlines using threat and error management system. LOSA has shown its success on the major improvement on many areas including the riskiest phase called the blue box, which is the busiest during approach and landing. Asiana Airlines has completed data collection in 2004 and round table for the data cleaning, to implement safety change process. The propose of this paper is to introduce the LOSA, ICAO DOC 9803, and the experience of Asiana.

  • 본 연구의 목적은 정보가 계약된 조건하에서의 다지역에 대한 지역간 산업연관표를 작성하고 이에 대한 정확성을 평가하는 데 있다. 지역간 산업연관표의 작성 방법은 이미 지난 1950년대 초 Isard 및 Leontief 등에 의하여 개발된 이 후 다양한 기법들이 제시되어왔다. 이들 기법 중에서 정확성 면에서는 실제 조사를 통하여 지역간 산업연관표를 작성하는 것이 가장 바람직하지만, 이 경우 많은 시간과 경비를 부담해야만 하는 현실적 어려움이 수반된다. 따라서 은 연구에서는 정보, 특히 지역수준에서 최종수요 및 지역간 상품의 흐름에 대한 정보가 제약된 조건하에서 우리나라의 전국을 5개 지역으로, 그리고 전 산업을 13개 부문으로 구분하여 비조사방법에 의하여 지역간 산업연관표를 작성하였다. 비조사방법에 의하여 지역간 산업연관표를 작성하는 방법에도 여러 가지가 있지만, 본 인구에서는 기본적인 LQ 기법을 원용하여 이를 다지역 모형으로의 확장을 시도하였다. 끝으로 추정된 투입계수의 정확성을 평가하기 위하여, 특정 지역 투자의 지역 및 지역간 파급효과를 분석하고, 이를 기존의 실제 조사를 통한 투입계수와 비교 해 보았다.

  • 하나의 서버 시스템에 여러 운영체제를 사용하거나 사용자간 메모리를 공유하는 클라우드 환경에서 공격자는 캐시 부채널 공격을 통해 비밀 정보를 유출할 수 있다. 본 논문에서는 국내 표준 블록 암호 알고리즘인 ARIA를 사전 연산 테이블 기반 최적화 기법을 이용해 구현할 경우, 캐시 부채널 공격의 일종인 Flush+Reload 공격이 적용되는 것을 확인하였다. ARIA-128을 대상으로 한 Ubuntu 환경에서의 실험 결과, Flush+Reload 공격을 통해 16바이트의 마지막 라운드 키를 찾을 수 있었으며 나아가 마지막 라운드 키와 첫 번째 라운드 키를 이용하면 마스터 키를 찾을 수 있음을 증명하였다.
