Under the leadership of Narendra Modi, India has pursued a hedging policy against China by seeking much closer alignment with the United States and at the same time maintaining stable bilateral diplomatic relations with China. Such policy behavior of Modi’s government is considered deviant from the past foreign policy decisions conducted by the previous Prime Minister, Manmohan Singh. This paper argues that one of the key determinants to India’s hedging against China is the political ideology of Modi’s Bharatiya Janata Party. The underpinning ideology of Hindu nationalism led the policy decision makers to depart from previous Nehruvian principle and to react more sensitively to India’s security challenges

Daesoonjinlihoe and Buddhism have found the cause of grudge and agony in the human mind. Fundamentally human being suffers grudge and agony which man in it self makes unless he acquire what he wants. So if human being recognizes the cause of that, the cause would disappear. And there are certainly needed regulation of ‘dosu’ in Daesoonjinlihoe. That implies the limitation of human effort. The worlds of heaven, earth, human being have to stand up in the same time, and there would appear paradise. In that case human being and the world of divinities are able to be relieved. Compared to that, Buddhism does not admit other Power without human effort and cultivation on oneself. Epistemological awakening of the ‘solution of grudge(haewon)’ and mokṣa accompany the ‘saving each other(sangsaeng)’ and maitrī․karuṇā. ‘Haewon’ and ‘sangsaeng’ have causal relation, further more epistemological awakening of ‘haewon’ and practical virtue of ‘sangsaeng’ would not be detached.

This is a survey on congenital posterolateral diaphragmatic hernia, conducted by the Korean Association of Pediatric Surgeons(KAPS). A registration form for each patient during the 5-year-period between 1998 and 2002 and a questionaire were sent to each member. Twenty-ninemembers in 22 institutions returned completed forms. The average number of patients per surgeon was 1.4 cases a year. The male to female ratio was 1.64: 1, and annual incidencewas 1/14,522 live births. In this review, factors influencing survival in congenital posterolateral diaphragmatic hernia were age at admission, birth weight, time of antenatal diagnosis, birth place, Apgar score, onset time of symptoms and signs, preoperative cardiopulmonary resuscitation, associated anomalies of themusculoskeletal system, central nervous system, or chromosomes, preoperative stabilization, levels of preoperative $FiO_2$, pH, and $AaDO_2$, perioperative complications, bilaterality of defect, size of the defect, and presence or absence of hernia sac.
Neutron Science Facility for Neutron Time-of-flight and Fission Cross-section Measurements at RAON
김재천,김기동,손재범,이철우,이영욱 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.3
In the middle of 2018, a heavy-ion accelerator complex that will be built in South Korea plans toprovide the first primary beams into the neutron science facility (NSF) for producing fast neutrons. Deuteron with a maximum energy of 53 MeV and protons with a maximum energy of 88 MeVaccelerated by superconducting driver linac (SCL1) will be delivered into the target hall at theNSF. A pulsed neutron beam will be provided for neutron time-of-flight (TOF) and neutron-inducedreaction cross-section measurements. At the NSF, white and mono-energetic fast neutrons will beproduced when either a deuteron or a proton beam bombards a light nuclei target such as C andLi. Preliminary thermal calculations have been performed with a rotating C (graphite) target andits maximum temperature was about 530◦C, much less than its melting point. For neutron TOFmeasurements, two flight paths of 5 m and 20 m are considered for high-flux and low-energy neutronbeams, respectively. Basically, 0◦and 30◦neutron collimators will be considered to obtain variousneutron energies for the neutron TOF measurements. A clearing magnet is used to deflect theproton beam to a beam dump when it crosses a thin target. In addition, the neutron beam dumpwill be designed to generate a background due to back-scattered neutrons and photons that shouldbe as low as possible in the TOF area. Fission cross-section measurements with a few percentuncertainties are set to be a short-term ultimate goal after building the neutron TOF facility atthe NSF. In order to achieve few-percent fission cross-section measurements at the NSF, we plan toemploy a time projection chamber (TPC). It can measure charged particle trajectories in the activevolume in three dimensions, as well as the energy deposition, and it can significantly improve theaccuracies of the fission cross-section measurements.
바이올린 음원을 이용한 스펙트랄 롤오프 포인트의 최적점 검출
김재천,Kim, Jae-Chun 한국컴퓨터정보학회 2007 韓國컴퓨터情報學會論文誌 Vol.12 No.1
음악을 분류하기 위해 특성함수를 사용하여 추출한 특성값 벡터를 사용한다. 본 실험에서는 특성값 벡터를 추출하기 위해 스펙트랄 롤오프, 분산, 평균 피크레벨을 사용하였다. 이중에서 스펙트랄 롤오프는 저음프레임과 고음프레임의 상대적인 비를 나타낸다. 최적의 롤오프 포인트를 찾기 위하여 롤오프 포인트를 0.05에서 0.9까지 0.05간격으로 증가시키며 반복실험 하였다. 롤오프 포인트를 증가시키며 분류성공률을 관찰하였다. 그리고 실험에 사용된 음원데이터는 바로크바이올린과 현대바이올린 연주이다. 두 종류의 악기는 모양과 주파수대역에 있어서 유사하지만 약간의 대역차와 질감의 차이를 가지고 있다. 이러한 특성이 최적의 롤오프 포인트를 찾는데 유용할 것으로 판단하였다. 실험결과 롤오프 포인트 0.85에서 가장 높은 분류성공률 85%를 나타냈다. Feature functions were used for the classification of music. The spectral roll-off, variance, average peak level, and class were chosen to make up a feature function vector. Among these, it is the spectral roll-off function that has a low-frequency to high-frequency ratio. To find the optimal roll-off point, the roll-off points from 0.05 to 0.95 were swept. The classification success rate was monitored as the roll-off point was being changed. The data that were used for the experiments were taken from the sounds made by a modern violin and a baroque one. Their shapes and sounds are similar, but they differ slightly in sound texture. As such, the data obtained from the sounds of these two kinds of violin can be useful in finding an adequate roll-off point. The optimal roll-off point, as determined through the experiment, was 0.85. At this point, the classification success rate was 85%, which was the highest.

Why do religions emphasize good deeds like charity or love? What kind of relation are there between good deeds and salvation? Early Buddhism stresses that the deed of mortal cannot escape retribution. And deeds are intentional act, so those are representation of mind. Therefore an issue of mind raises its head before action. The extinction of ignorance and thirsty gives rise to good mind, and the good mind produces good deed. Mahāyāna Buddhism accentuates charity. It signifies that the mind of oneself sympathizes the mind of others. That is impossible unless one throws away attachment to oneself. The alms deed makes that possible. In Roman Catholicism Ten Commandments assert absolute worship to god. The transcendental merits devaluate worldly ones, so the mind can obtain calmness. Protestant claims the one can acquire salvation only by faith. And the salvation leads human to good deed. In conclusion good deeds are not ways and means to mokṣa or grace, but identical with them in Early Buddhism and Mahāyāna Buddhism, and Roman Catholicism and Protestant.
