Purpose: The purpose of this study is to evaluate current criteria for insurance coverage by Health Insurance Review & Assessment Service (HIRA) on the systemic therapy used in the treatment of advanced or metastatic renal cell carcinoma (RCC), by reviewing all available clinical evidences including a variety of clinical practice guidelines. Methods: We searched clinical databases and collected data from published phase 1 through 3 randomized clinical trials on all systemic therapies used in RCC, including novel targeted therapies. Additionally, current clinical practice guidelines on the management of kidney cancer or RCC were reviewed. Based on the collected data we evaluated the appropriateness of the HIRA criteria for insurance coverage on the systemic therapy of RCC whether they are evidence-based and up to date. Results: On the basis of the collected data we concluded that there was a need for a revision in HIRA criteria for systemic therapy of RCC. Despite recent emerging therapeutic advances and changes in therapeutic strategies of management of RCC, some of anticancer regimens were inappropriately listed even though they were not proven to provide efficacy or safety superior to those of other therapies. We thus proposed an updated recommendation based on current clinical evidences. Conclusion: Systemic therapy of RCC is being rapidly changed with the advancement of understanding of the molecular biology of cancer. Consequently newly developed targeted therapies are becoming the standard therapy in the management of medically or surgically unresectable advanced or metastatic RCC. To provide effective and safe therapy to patients with RCC, the criteria for insurance coverage should be made carefully taking into consideration of most up-to-date and high-quality clinical evidences, and should be continuously reviewed so as to reflect evidence-based clinical practice.

The traditionally useful coverage methods of the wrist and hand soft tissue defect are the chinese forearm flap, the ulnar forearm flap. But, this flaps are inevitably sacrifice major vessel to the hand. Advantages of the posterior interosseous artery island flap(PIA Flap) is no need to sacrifice blood supply to the hand and supply relatively large thin, good quality flap and more cosmetic than other forearm flaps. But, it is difficult to dissect and raise because of deep seat, close relation with the posterior interosseous nerve and anatomic variation. Authors evaluated 8 cases of 7 patients in the department of orthopaedic surgery, college of medicine, Hallym University from January, 1993 to December, 1995. The results are as follows: 1. The satisfactory coverage was achieved 7 cases and 1 case failed because of anatomic variation. 2 The pedicle length is average 9cm and the flap size is variable from 3cm by 4cm to 5cm by 8cm. 3. The donor site defect was repaired by direct closure in 5 cases, remained 3 cases combined with skin graft. From our experience we conclude that the PIA flap is one of the useful coverage methods of the wrist and hand soft tissue defect.

Since the 1990s, the application of Kentucky bluegrass cultivars has increased in newly-constructed Korean golf courses as opposed to the previously-used zoysiagrass. However, there have been few reports studying the selection and characterization of these Kentucky bluegrass cultivars under Korean weather conditions. A total of 12 Kentucky bluegrass cultivars were tested for their adaptability in environmental stresses during summer conditions in Korea in order to select the best Kentucky bluegrass cultivars for use in Korean golf courses. This study found that two Kentucky bluegrass cultivars ('Midnight' and 'Bluestone') maintained their green throughout the summer season and had a high degree of root density, as compared to the other cultivars tested. These two cultivars also had a good rate of coverage in the early growth period. These characteristics make them suitable for application on sports fields and golf courses, which receive many divots and the frequent replacement of turfgrass sod caused by both biotic and abiotic stress. Two other cultivars, the 'Ginney' and 'Nuglade', also displayed good visual quality and high rate of coverage under summer conditions. In conclusion, the 'Midnight' and 'Bluestone' cultivars performed well in areas including the maintenance of their green color, the number of roots and the rate of coverage during the summer months. These characteristics are necessary for golf courses sports fields, which receive many divots and requirethe frequent replacement of turfgrass. further research on a range of Kentucky bluegrass cultivars, including a sensitivity test for many pathogens and recovery rates from a variety of stresses, is required in the near future.

As the elderly population increases, they are increasingly affected by oral health problems. Therefore, efforts are being made to improve the oral health of older people, alleviate mental discomfort, and reduce unmet dental needs. This study was conducted to confirm the relationship between the National Health Insurance Elderly Denture Coverage and the unmet dental need for the edentulous elderly, as part of the protection policy. We analyzed the 2011 and 2013 Community Health Survey data of the edentulous elderly, aged 75 years or older, before 2012. In order to more precisely confirm the effects of the denture donation policy on unmet dental care, basic life recipients who were subject to the free elderly prosthetic project were excluded from the analysis. The final analysis included 20,400 subjects. According to our investigation of the factors that affect the unmet dental needs of the elderly, the National Health Insurance Elderly Denture Coverage did not affect unmet dental needs. The statistically significant variables that affected the unmet dental needs of the elderly were education and income levels, which are representative socioeconomic status variables. The lower the level of education, the unhealthier the dental care experience, and income levels showed a similar tendency. The elderly who have a low socioeconomic status are more likely to experience unmet dental needs because they lack the knowledge and socioeconomic ability to pay for dental care. Therefore, the policy for health protection of the entire elderly population should be continuously expanded. In addition, the socioeconomically vulnerable groups may have health problems due to the restriction of medical use, which may lead to quality of life deterioration.

The historical study reveals that our ancestors had maintained a system which could produce data on population and households. The main purposes of maintaing the system at that time were taxation and conscription. At the present time, however, there are three major data sources which produce the statistics on pop-ulation and households in Korea : Civil Registration System, Resident Registration System and Popula-tion Census. These three systems are found to have some problems. there are some inherent problems in the regis-tration systems, such as problems in its coverage, accuracies in contents and timeliness in reporting the vital events and publishing the results. The population census has also non- sampling erors, such as errors in coverage, respone and non-response. Apart from the above mentioned problems, there are also conflicting problems arised from having three data sources, We can find some overlapping problems and difficulties in comparative studies. In the future, these problems should be considered for the improvement of the quality of statistics on population and household.

Objectives : Despite the substantial amount of newspaper coverage related to complementary and alternative medicine on the internet in recent years, little is know about the quality of the health information. To evaluate health information of the newspaper articles on moxibustion available in Korea through Korean language search engines and Web sites. Methods : We searched 454 news stories about moxibustion between 1 January 2006 and 31 December 2008. Among them, 34 internet news coverage related to health information on moxibustion were selected and rated against eight categories by two individuals. Results : The inter-rater reliability of the two reviewers was assessed as 0.69, indicating a moderately high level of agreement. The overall rating score for 34 articles was 35.7${\pm}$17.2 for the statement criteria and 12.9${\pm}$17.0 for the satisfaction criteria. Overall, although they might be improving recently, the scores remain generally low. There was a statistically significant difference in the score of the newspaper coverage according to the type of evidence sources, including anecdotes. Conclusions : There is substantial variability in news reporting practices about moxibustion. It is urgently needed to enhance the information related to CAM including moxibustion through the news media in Korea.

5G 서비스는 기존 이동통신주파수보다 상대적으로 높은 중대역(n78)을 사용하고 있어서 2GHz 이하의 저대역 주파수를 활용하여 5G 커버리지 개선이 필요하다. 이를 위해서는 저대역 주파수의 대부분을 사용하는 LTE와 5G-NR 시스템의 동적 스펙트럼 공유(Dynamic Spectrum Sharing) 기술의 적용이 요구된다. 본 논문에서는 DSS 적용을 위한 시그널링 오버헤드 요소와 단말기 구현 RF 이슈들을 도출하고, 저대역 주파수 중 광대역 주파수 활용이 가능한 1.8GHz 대역(50MHz 폭)에 대해 5G-NR과 LTE 각각의 관점에서 시그널링 오버헤드 비율과 단말기 RF 이슈들을 분석하였다. 분석 결과들을 통해 저대역을 활용한 DSS 기술을 적용한다면 LTE 트래픽이 5G-NR로 빠르게 이전할 경우, 5G 커버리지 개선으로 인해 우수한 서비스 품질을 제공할 수 있을 것으로 예상된다.

Total Quality Management (TQM) is the aggregated management philosophy for quality including production, operation, human resource, leadership, marketing, and etc. TQM is the advanced concept and philosophy rather than traditional "Quality Control" or "Quality Assurance". Nowadays, downstream costs has been increased, that made cost accountants' attention to costs of quality. Many countries have developed their own quality awards system in order to improve overall national quality level. The Deming Prize of Japan and Malcolm Baldrige National Quality Award (MBNQA) of United States are two representatives of quality prizes. We compared the two awards by means of their history, objective, coverage, and judging criteria. Deming Prize has a longer history than MBNQA. Deming Prize selects five winners a year, while MBNQA has two or three areas. The biggest difference is judgement criteria. The Deming Prizes focuses on statistical control which is a traditional quality control method, while MBNQA concentrates on modem business concept such as customer satisfaction. The suggestions to these awards are: evaluate more on information of quality; evaluate more on inter-functional relationship between quality control function and other link more financial success.e financial success.
