This report present the result of the national survey of pediatric surgeons' preferences on diagnosis and treatment of Hirschsprung's disease(HD) carried out in 1993. The questionnaires were sent to twenty-seven members of the Korean Association of Pediatric Surgeons (KAPS) working in twenty-four institutions. The questionnaires were designed to determine the individual surgeon's preference for the methods of diagnosis and treatment of the disease. Twenty-three pediatric surgeons from twenty institutions returned completed forms. The total number of patients diagnosed with HD in 1992 was 190 in this group. The estimated incidence of HD was 1/3,900. The most important symptom was delayed meconium passing and the most preferred diagnostic procedure was barium study. Anorectal manometric examination was carried out by 13 pediatric surgeons and 19 confirmed the diagnosis before operation by rectal biopsy, 12 with full-thickness biopsy and 7 with suction. Frozen section biopsy during operation was done by 22 surgeons. Eight surgeons did one stage operation if the age of the patient is suitable. Definitive operation was usually done at the age of 6 to 11 months. The most preferred operation was Duhamel procedure done by 19. Enterocolitis was the most serious complication of HD. Most of patients had normal continence within 6 to 12 months after operation. The follow-up period was less than 6 years in 16 surgeons. The results were presented at the 9th annual meeting of KAPS in June of 1993. This is the first national survey of HD and it can provide guidelines of diagnosis and treatment of Hirschprung's disease even though it is not a detailed study of patient data.

이호흡기 질환에 영향을 미치는 요인을 규명 하고져 대기오염 측정망이 있는 우리나라 52개 주요 도시의 오존 측정 자료와, 전국 건강보험 자료에서 같은 도시의 만성 호흡기 질환 이환율을 측정하고, 통계청 자료를 이용하여 52개 도시를 생태적 특성으로 분류하였고 52개 도시를 분석단위로 생태적 연구를 실시하였다. 연구 결과 우리나라 주요도시의 만성 호흡기 질환 이환율은 서울이나 수도권 보다 해안 산업화 도시가 높은 경향을 보였다. GIS에 의한 만성 호흡기 질환 이환율과 오존농도의 분포는 매우 유사하였다. 호흡기질환에 영향을 주는 요인은 호흡기 질환 입원율과 외래 방문을 모두 오존 농도와 해안지역이 영향을 미친 것으로 보이나 노인인구 비율 변수를 추가하면 노인인구 비율이 높은 영향을 미쳤고 흡연비율과 해안지역이 영향을 미치는 것으로 분석되었다. 본 연구 결과로 만성호홉기질환에 영향을 주는 요인은 노인인구비율은 물론이고, 오존농도와 흡연비율, 해안 도시 등이 위험요인으로 작용할 가능성 있는 것으로 보이지만 이 연구결과 만으로 단정 하기는 어렵다. 따라서 향후 만성호흡기 질환관리를 위하여 보다 구체적인 위험요인 규명이 필요하다고 생각된다.

We have always attempted to create a standard treatment protocol for patients with gastric cancer. However, many debates still exist regarding gastric cancer treatment. For the past 2 years, at the Annual Congress of the Korean Gastric Cancer Association, we have presented a grand symposium on the "Debates on the strategy for treating gastric cancer". In 2008, four major topics were discussed and voted on after discussion. The four major topics were proximal location treatment for early gastric cancer, management choices for pyloric obstruction with advanced gastric cancer, management of liver metastasis, and reconstruction methods after a distal gastrectomy. The opinions of the audience for six minor topics were expressed by an electronic voting system. In 2009, the four main topics were treatment for submucosal tumor sized around 2 cm, laparoscopic gastrectomy in T2N1 gastric cancer, choices for managing gastric lymphoma, and application of a pylorus preserving procedure for early gastric cancer at the antrum. The opinions of the audience for these six minor topics were expressed by an electronic voting system, as was conducted in 2008. It was good opportunity to identify a point of contact about the debates on managing gastric cancer. The results of these debates and studies will identify the best methods to treat patients with gastric cancer.

Objectives : Based on the system and control activity for the monitoring system made of components for infection control at dental hospitals and infection rate reporting, and the role of trained infection control staff, this study tried to understand approaches to the effective infection control program by surveying infection control at dental hospitals in Korea. Methods : The survey was conducted from December 14,2010 to January 31,2011 for 121 dental hospitals in Korea. For statistical analysis, PASW Statistic 18 was used. Results : And following conclusions were reached. 1. As for the infection control system at dental hospitals, 54.7% has an infection control committee, 58.7% infection control staff, 78.5% infection control rules, and 39.7% annual infection control plan and record. 2. As for surveillance indexes to report infection rates, 50.4% has the reporting system for staff's exposure to infectious disease and needle pricking. The average number of exposures to infectious disease was $0.28{\pm}2.23$ and that of needle pricking was $1.83{\pm}5.39$. 3. As for infection control indexes, it was reviewed whether infection control rules were implemented according to operation agents, general hospitals were more active in staff infection control, and hospitals annexed to a dental university or special legal entity were more active in microorganism control. As for use of personal protection gear, there was no significant difference among operation agents. More than 71% of operators and their assistants said they did not replace their masks between patients. 4. As for personnel indexes for effective infection control staff, most hospitals designated dental hygienists, which was followed by dental doctors (or doctors). Where their workload was reviewed, the ratio of other work such as treatment was relatively higher than that of infection control (n=71). Conclusions : These results show dental hospitals in Korea have a certain level of infection control system. As infection indexes are managed mainly for staff members, patient monitoring is needed, and trained and effective infection control staff should be designated. This study reviewed surveillance, infection control and personnel indexes. And further studies are needed in the future.

This study was carried out to calculate working life expectancy and its potential gains according to the degree of reduction in the specific causes of death. It sought to ascertain what potential gains in labor force longevity might be reasonably achieved through efforts to reduce mortality from injuries and poisoning, diseases of circulatory system, neoplasms and the other causes of death. The data were drawn from the three sources such as "The 1982 Causes of Death Statistics," "Abridged Life Table for Korea 1978~'79" and "The 1982 annual Report of Economically Active Population" issued by Economic Planning Board. Analytical tools used in this study were the cause-deleted life table and the Wolfbein Wool's working life table method. Partial life expectancy was adopted as an index of this study, This application will be widely used as a good demographic tool for analyzing the dynamics of labor force and causes of death. Some of the findings are summerized as follows. 1. Partial life expectancies from initial age 15, 25, and 45 respectively to terminal age 65 are 44.86, 35.59 and 17.41 year in life expectancy itself, 37.08, 32.83 and 15.21 year in working life expectancy, 7.78, 2.76 and 2.20 years in inactive life years. 2. Potential gains in working expectancy from initial age 15, 25 and 45 to terminal age 65 by the complete elimination of the specific causes of death are 1.36, 0.94 and 0.27 years in injuries and poisoning, 0.88, 0.83 and 0.54 years in diseases of circulatory system, 0.56, 0.54 and 0.37 years in neoplasms, 1.13, 1.02 and 0.58 years in the other causes of death. The relationship between degree of reduction in causes of death and potential gains in working life years is in direct proportion. The prime orders of reduction effectiveness in age groups by the causes of death are injuries and poisoning in age 15-24, the other causes of death in age 25-49 and diseases of circulatory system in age 50 and over. 3. If it were possible to reduce 25%, 50% and 75% in mortality condition 1978~'79, the average length of working life would be 38.08, 39.13 and 40.17 years in age 15, and 33.68, 34.57 and 35.44 years in age 25, and 15.67, 16.14 and 16.63 years in age 45.

Purpose: Variations in the preferred conservative and operative treatment methods for ankle arthritis may be observed in the practice of orthopedic surgeons. This study is based on the Korean Foot and Ankle Society (KFAS) member survey and aims to report the current trend and changes in the management of ankle arthritis over the last few decades. Materials and Methods: A web-based questionnaire containing 24 questions was sent to all KFAS members in July 2021. The questions were mainly related to the preferred techniques and clinical experience in osteotomy, arthrodesis, and total ankle arthroplasty (TAA) for patients with ankle arthritis. Results: Sixty-three out of 550 surgeons (11.5%) responded to the survey. The responses to 6 out of the total of 24 questions (25.0%) achieved the levels needed to reflect a tendency. Answers that showed a tendency were related to the following: a surgical approach for arthrodesis (anterior approach), use of auto-bone graft for arthrodesis (iliac bone), a nonunion rate of more than 10% following arthrodesis, main reason related to unsatisfactory results after arthrodesis (nonunion or delayed union), the main reason to change total ankle prosthesis (unstable supply of prosthesis), the unusualness of revision TAA and conversion of fusion to TAA. Diversity was found in several aspects of treatment (degree of experience and satisfaction in supramalleolar osteotomy, fixation method for arthrodesis, preferred TAA prosthesis and longevity, degree of experinece, annual number of TAA operation. Conclusion: This study proposes updated information with regard to the current trends in the management of ankle arthritis in Korea. Both consensus and variations in the approach to patients with ankle arthritis were identified through this survey. With an increasing preference for TAA, the need for the development of a prosthesis optimized for Koreans and a stable supply of prostheses were the suggestions made by the study.

Eclipta prostrata and E. alba are annual herbal medicinal plants and have been used as Chinese medicinal tonics. Both species are widely distributed in tropical and subtropical regions as well as in Korea. Both species have similar morphological features but E. alba has smoother leaf blade margins compared with E. prostrata. Although both species are utilized as oriental medicines, E. prostrata is more widely used than E. alba. Morphological semblances have confounded identification of either species. Here, we report the complete chloroplast genomes of both species to provide an authentication system between the two species and understand their diversity. Both chloroplast genomes were 151,733-151,757 bp long and composed of a large single copy (83,285-83,300 bp), a small single copy (18,283-18,346 bp), and a pair of inverted repeats (25,075-25,063 bp). Gene annotation revealed 80 protein coding genes, 30 tRNA genes and four rRNA genes. A phylogenetic analysis revealed that the genus Eclipta is grouped with Heliantheae tribe species in the Asteraceae family. A comparative analysis verified 29 InDels and 58 SNPs between chloroplast genomes of E. prostrata and E. alba. The low chloroplast genome sequence diversity indicates that both species are really close to each other and are not completely diverged yet. We developed six DNA markers that distinguish E. prostrata and E. alba based on the polymorphisms of chloroplast genomes between E. prostrata and E. alba. The chloroplast genome sequences and the molecular markers generated in this study will be useful for further research of Eclipta species and accurate classification of medicinal herbs.
