주관절 전치환술은 과거 임상적 결과를 토대로 새로운 디자인이 개발 중이며 불안정성이나 해리 등의 단점을 개선하고 수명을 향상시킬 수 있을 것으로 기대된다. 본 종설은 비연결형 주관절 치환술과 전환형 주관절 치환술의 일반적 개념을 기술하고자 한다. 과거의 비연결형 치환물 중 현재는 일부만 사용되고 있다. 기존의 단점을 보완한 최근의 비연결형 디자인은 더 안정적인 관절면 모양, 스템형 치환물 및 요골-소두 치환술을 첨가하는 형태 등으로 개선되고 있다. 전환형 디자인은 전세계적으로 두 개의 모델이 개발되어 사용 중이며 최근 국내에서도 사용 가능하게 되었다. 비연결형 디자인에서 추가적인 연결고리를 이용하면 쉽게 연결형으로 전환이 가능하다. 비연결형 주관절 치환술은 인체 주관절과 유사한 운동 구조를 가지게 되어 폴리에틸렌 마모나 치환물의 해리를 감소시킬 수 있는 장점이 있다. 주변골과 연부 조직이 보존된 경우 또는 활동도가 높은 젊은 환자에서 적응증이 될 수 있다. 전환형 주관절 치환술은 치환물의 선택을 넓히고 재수술을 용이하게 하는 장점을 가지고 있다. 두 개의 치환물의 사용은 연결형 치환술이 가지고 있는 단점을 보완하고 장기적인 결과를 향상시킬 수 있을 것으로 기대된다.

Total elbow prostheses which are now available in clinical use can generally be classified into two major categories ; one bing linked prostheses, another being unlinked prostheses. Of those two categories I am dealing here only with the problems of the unlinked type prosthesis, particularly with those of non-constrained, surface-replacement prostheses. Furthermore, my presentations this time may have to be narrowed down only to the topics regrading the particular features and some of the technical problems with Kudo Elbow Prosthesis, due to the time limit assigned for this presentation.

목적: 주관절에 대한 인공 관절 성형술은 아직도 슬관절이나 고관절에서의 그것에 비해 정설이 정립되지 않은 분야이다. 치환물의 디자인이나 수술 술기면에서 많은 발전이 이루어지고 있지만, 여전히 문헌상 보고되는 장기 추시 결과는 많지 않은 실정이다. 여기에서는 현재 사용되고 있는 다양한 주관절 치환물에 대해 전반적으로 살펴보고자 하였다. 대상 및 방법: 주관절에 대한 인공 관절 성형술에 사용되는 치환물은 크게 3개로 분류되고 있다. 비구속형과 구속형, 그리고 전환 가능한 치환물이 그것이다. 이들 각각 치환물의 특징 및 현재의 경과 등에 대해 살펴보았다. 결과 및 결론: 주관절에 대한 인공 관절 성형술에 있어서 치환물의 형태 자체보다는 이를 적절히 적용하기 위한 적절한 환자의 선택, 지속적인 치환물 디자인의 개선, 수술 술기의 발달, 적절한 수술 후 재활 치료 등과 같은 요인 역시 중요하다.

First, the coupling faults of semiconductor memory are classified in detail. The chained coupling fault is introduced and defined, which results from sequential influencing of the coupling effects among memory cells, and its mapping relation is described. The linked coupling fault and its order are defined. Second, the deterministic “Algorithm GA” is proposed, which detects stuack-at faults, transition faults, address decoder faults, unlinked 2-coupling faults, and unlinked chained coupling faults. The time complexity and the fault coverage are improved in this algorithm. Third, it is proved that the march test of an address sequence can detect 97.796% of the linked 2-coupling faults with order 2. The deterministic “Algorithm NA” proposed can detect to the limit. The time complexity and the fault coverage are improved in this algorithm.

Objectives: Korea and Japan have managed the spread of coronavirus disease 2019 (COVID-19) using markedly different policies, referred to as the "3T" and "3C" strategies, respectively. This study examined these differences to assess the roles of active testing and contact tracing as non-pharmaceutical interventions (NPIs). We compared the proportion of unlinked cases (UCs) and test positivity rate (TPR) as indicators of tracing and testing capacities. Methods: We outlined the evolution of NPI policies and investigated temporal trends in their correlations with UCs, confirmed cases, and TPR prior to the Omicron peak. Spearman correlation coefficients were reported between the proportion of UCs, confirmed cases, and TPR. The Fisher r-to-z transformation was employed to examine the significance of differences between correlation coefficients. Results: The proportion of UCs was significantly correlated with confirmed cases (r=0.995, p<0.001) and TPR (r=0.659, p<0.001) in Korea and with confirmed cases (r=0.437, p<0.001) and TPR (r=0.429, p<0.001) in Japan. The Fisher r-to-z test revealed significant differences in correlation coefficients between the proportion of UCs and confirmed cases (z=16.07, p<0.001) and between the proportion of UCs and TPR (z=2.12, p=0.034) in Korea and Japan. Conclusions: Higher UCs were associated with increases in confirmed cases and TPR, indicating the importance of combining testing and contact tracing in controlling COVID-19. The implementation of stricter policies led to stronger correlations between these indicators. The proportion of UCs and TPR effectively indicated the effectiveness of NPIs. If the proportion of UCs shows an upward trend, more testing and contact tracing may be required.

Today the pedestrian-related problems a key subject requiring the attention of the traffic engineers for improving the transportation system. Particularly in urban and CBD locations, the pedestrian presents an element of sharp conflict with vehicular traffic. Therefore pedestrian movements must be studied for the purpose of providing guideline for the design and operation of walking transportation systems. This paper is to address the characteristics of walking transportation in a big city. Especially the focuses are emphasized on the ratio occupied by pedestrian traffic among the whole unlinked trips in a city and walking time. The data for analysis are collected in Seoul metropolitan city through sampling 1,006 citizens. Compared with other similar research works this paper utilized diversified tools to acquire more useful results. Finally, policy directions for pedestrian environment improvement were suggested.

Potato virus X (PVX) resistance in potato is one of the best-characterized resistance models, however little is known in pepper. To evaluate the resistance to PVX in Capsicum annuum, a total of eleven pepper accessions were used for resistance screening against two PVX strains, USA and UK3. None of them were resistant against strain UK3, whereas four resistant genotypes were found against strain USA, three of which were further characterized. Two unlinked dominant genes were identified for both genotypes Bukang and Perennial; resistance in the genotype CV3 seemed to be conferred by two complementary dominant genes. These results demonstrated that the resistance to PVX in C. annuum is different from that in potato. This is the first report on genetic analysis of PVX resistance in C. annuum.

Authority control enables us to retrieve information accurately by coordination and cross reference of headings. It is considered that authority control is needed in machine readable catalogs as well as in conventional catalogs. Taylor, Maxwell and Frost divided automated authority control systems into major vendor and network systems then available into two groups. The first group was defined as a system that processes a library's machine readable catalogs on the tape against an automated authority file. The second group offers an online access to catalogs and authority records. This group was further subdivided into linked or integrated systems and unlinked systems. If authority work is shared with many libraries the costs can be considerably reduced and the quality of catalog data base can be controled by standardization of headings used in participating libraries. The NACO is a project for sharing of authority records started in 1977 by L.C. And LSP furthers the ability to share authority records. A project as the NACO is necessary not only in America but also in the other countries The responsible organizations for national bibliographies of the countries must take much interest in these matters.
