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.

Objectives: This study aimed to investigate the opinions of Korean medical doctors on how to elucidate possible remedial measures for expanding the health insurance benefits coverage item of Korean medicine (KM). Methods: An online survey was conducted to all members who had registered e-mail address in the association of Korean medicine from 1 to 17 November, 2016. Statistical analysis was performed and odds ratio with 95% confidence interval were calculated by each subgroup. Results: A total of 743 members answered the questions and the response rate was 4.1%. The priorities for expanding health insurance benefits were as follows: thermographic imaging, Sasang constitution typing test, and pulse wave among examinations; pharamacopuncture, embedding acupuncture, and acupotomy among procedures; Chuna manual therapy, manual therapy for meridian muscle, and Daoyin exercise therapy among manual therapies; low-frequency electrical therapy, traction, paraffin bath, and light therapy among physical therapies; and aromatherapy, enema therapy, and color therapy among activities of KM. Conclusions: It should be covered by the national health insurance (NHI) of KM that thermographic imaging, pharmacoacupuncture, Chuna manual therapy, low-frequency electrical therapy, aromatherapy as a top priority. We also suggest that basic medical tests, such as blood, urine, or imaging, should be included in the coverage of the NHI of KM. It is necessary to review the expertise and public opinions about the plans and priorities for the conversion of the desired medical services to be covered by the NHI.

Traditionally, the Supreme Court has held that medical treatment agreements covered by national health insurance should be distinguished from other medical treatment agreements which are viewed as a consummation of the autonomous free will between doctor and patient. Namely, the Supreme Court views medical treatment agreements covered by national health insurance to be bound by the National Health Insurance Law with the intent to promote the applicability and comprehensiveness of the national health insurance scheme. Yet, issues of voluntary non-reimbursable treatments are triggered not only by the mistakes or moral hazard of medical care institutions but also by systemic limitations of national health insurance coverage criteria. Thus, there is a need for legislative measures that allow certain medical treatments to be included or reflected in the national health insurance coverage system so that patients may receive prompt and flexible medical treatments. To reflect such concerns, the Supreme Court made an exception for voluntary non-reimbursable treatments and developed a strict test to be applied in such cases in Supreme Court Judgment 2010 Doo 27639, 27646 (ruled on June 8, 2012 by the Grand Bench). Such judgment, however, is not a fundamental overturn of the Supreme Court's prior rulings that voluntary non-reimbursable treatments are not allowed under the law. It is only a slight revision of its previous stance for cases in which there is a lack of legislative measures to make coverage of a new yet valid medical treatment possible under the current national health insurance coverage system.

도심지 무선 인터넷 서비스에서 전파 특성(wave propagation characteristics)을 정화하게 예측하여 서비스 영역을 결정하는데 있어서 최적의 기지국 선정, 셀 설계 등은 매우 중요한 과정이다. 서비스 지역의 지형 지물 및 인위적 구조물의 건물 재질 및 높이와 폭 등 각기 다른 특징으로 인하여 무선망 서비스의 송수신 거리에 큰 영향을 미치고 있으며, 이는 기본적으로 요구되어지는 무선 인터넷 품질을 정확하게 예측 및 분석하여 이용자에게 서비스를 제공하는데 큰 어려움을 갖게 한다. 본 논문에서는 이러한 문제점을 개선하기 위한 전파 예측 모델에 의한 기본 기지국 위치 선정 후 가장 서비스 영향을 미치는 기지국 위치 이동 및 안테나의 각도 등 무선망 최적화를 결정짓는 파라미터 값의 변화에 따라 서비스 영역이 최적화 되어 서비스 지역 덴 품질이 개선되는 과정을 시뮬레이션 함으로써 무선방 기지국 최적화 과정을 통하여 동일 지역 내 서비스 커버리지가 넓어지고 개선된 품질로서 이용자들이 질 높은 무선 인터넷 서비스를 제공받을 수 있게 된다는 것을 보여 주었다.

As the increasing integrity of VLSI, the BIST(Built-In Self Test) is used as an effective method to test chips. Generally the pseudo-random test pattern generation is used for BIST. But it requires too many test patterns when there exist random resistant faults. Therefore we propose a mixed test scheme which applies to the circuit under test, a deterministic test sequence followed by a pseudo-random one. This scheme allows the maximum fault coverage detection to be achieved, furthermore the silicon area overhead of the mixed hardware generator can be reduced.

본 논문에서는 무고정 부분 스캔 테스트 방법을 위한 새로운 스캔 선택 알고리즘에 대하여 논한다. 무고정 부분 스캔 테스트 방법은 모든 플립-플롭을 스캔하지 않는다는 점을 제외하면 완전 스캔과 동일한 테스트 방법이다. 이 테스트 방법은 테스트 벡터를 입력, 인가, 혹은 적용 등, 어느 때에도 스캔, 비스캔 중 어느 플립-플롭의 데이터 값도 고정하지 않는다. 제안된 스캔 선택 알고리즘은 무고정 부분 스캔 테스트 방법에서 완전 스캔 고장 검출율을 거의 유지하면서 많은 플립-플롭을 스캔하지 않게 한다.

In this paper, we propose a low power Scan-based Built-ln Self Test based on circuit partitioning and pattern suppression using modified test control unit. To partition a CUT(Circuit Under Testing), the MHPA(Multilevel Hypergraph Partition Algorithm) is used. As a result of circuit partition, we can reduce the total length of test pattern, so that power consumptions are decreased in test mode. Also, proposed Scan-based BIST architecture suppresses a redundant test pattern by inserting an additional decoder in BIST control unit. A decoder detects test pattern with high fault coverage, and applies it to partitioned circuits. Experimental result on the ISCAS benchmark circuits shows the efficiency of proposed low power BIST architecture.

In this paper, we propose a novel test methodology for the detection of catastrophic and parametric faults present in analog very large scale integration circuits. An automatic test pattern generation algorithm is proposed to generate piece-wise linear (PWL) stimulus using wavelets and a genetic algorithm. The PWL stimulus generated by the test algorithm is used as a test stimulus to the circuit under test. Faults are injected to the circuit under test and the wavelet coefficients obtained from the output response of the circuit. These coefficients are used to train the neural network for fault detection. The proposed method is validated with two IEEE benchmark circuits, namely, an operational amplifier and a state variable filter. This method gives 100% fault coverage for both catastrophic and parametric faults in these circuits.

We propose a modified mid P-value method to reduce the conservativeness for the inference of conditional associations in three-way contingency tables. This improves the ordinary mfd P-value method. For $2{\times} 2${\times} K$ tables, we propose confidence intervals for an assumed common odds ratio based on inverting two separate one-sided tests using the modified mid P-value. Also, an alternative and usually even better ways of constructing intervals, based on Inverting a two-sided test, are presented. The actual probability of coverage of a 100($1-\alpha$)% confidence interval is centered about the nominal level, but the modified mid P-value approach gives actual coverage probability even closer to the nominal level than the ordinary mid P-value approach.
