While corporate social responsibility (CSR) has been considered an important philanthropic support for nonprofits worldwide, little is known about how perceptions of CSR are associated with actual CSR practices that may benefit nonprofit organizations in different institutional contexts. This study applies stakeholder theory to examine how South Korean firms perceive CSR outcomes, and how these perceptions lead to different CSR practices. We constructed a panel dataset using two waves of the Giving Korea survey of CSR and two additional sources. The results indicate that perceived CSR outcomes may play a critical role in CSR practices: 1) the more financial performance is perceived as an outcome, the more will be donated; 2) the more organizational culture is perceived as an outcome, the greater the engagement in employee volunteering; and 3) the more reputation is perceived as an outcome, the more nonprofit organizations are supported. From the findings, we discuss theoretical implications and provide suggestions for nonprofit organizations.

Soybean is one of the world's most widely cultivated food crops, and soybean seeds are supplied from national seed resources in Korea. However, the transmission of seed-borne diseases through infected soybean seeds is problematic. Among these diseases, soybean seed decay is caused by Diaporthe spp. Infecting the pods, and the infected seeds show rotting symptoms. Most diseased seeds are removed during the selection process; however, it is difficult to distinguish infected seeds that do not display symptoms. Hence, a sequencebased method was devised to screen Diaporthe-infected seeds. Based on the nuclear ribosomal internal transcribe spacer (ITS) region of the pathogen, a primer was designed to distinguish the infection from other soybean seed pathogens. As a result of the comparison between healthy and Diaporthe-diseased seeds by using the primers, Diaporthe was detected only in the diseased seeds. Therefore, it is possible to distribute healthy soybean seeds by detecting Diaporthe-diseased seeds at the genetic level using the Diaporthe-specific primers.

본 논문에서는 사용자의 입장에서 게임 논리와 밸런스를 바탕으로 흥미를 유발할 수 있는 게임 개발의 요구를 고려하여 언리언 엔진 5 기반 하이퍼 FPS 게임의 설계와 구현을 제안한다. FPS 게임 내에도 정통 FPS, 배틀로얄, 그리고 하이퍼 FPS 등 여러 종류가 있는데 그 중 순전히 총으로만 싸우지 않고 캐릭터마다 고유스킬을 사용하여 전투할 수 있는 것이 하이퍼 FPS이다. 제안하는 게임 개발을 위해 다양한 게임엔진 중에서 사용자 친화적인 인터페이스와 비교적 쉬운 작업 흐름을 가지고 있는 언리얼 엔진을 선정하였다. 개발 결과의 테스트를 통해 제안한 게임과 EOS(Epic Online Services) 연동으로 다중 사용자들의 접속과 플레이를 확인하였다.

BitLocker는 2006년에 Microsoft가 새롭게 출시한 운영체제인 Windows Vista에서 처음 사용되는 보안 메커니즘이다. 기존의 다양한 운영체제에서 사용되는 보안 메커니즘은 기본적으로 사용자가 로그인한 후 로그인한 사용자의 데이터를 바탕으로 파일에 대한 암호화, 데이터에 접근에 관한 권한 확인과 같은 방법을 사용하여 데이터를 보호했다. 하지만 이러한 보안 메커니즘은 물리적으로 접근하는 공격방법에는 취약하고, 플랫폼 자체에 대한 신뢰성이 부족하기 때문에 새롭게 Microsoft에서 새롭게 제안하는 보안 메커니즘인 BitLocker는 디스크 자체를 암호화 해서 보호하는 새로운 메커니즘이다. 본 논문에서는 Windows Vista에서 사용되는 새로운 보안 메커니즘인 BitLocker의 운영 메커니즘에 대해서 분석하고 이를 바탕으로 Windows 보안 메커니즘에 대한 취약점을 검증하기 위한 기존 자료로 활용하였다.

A 30-year-old male novice golfer was diagnosed with a clay-shoveler's fracture. During golf practice, he experienced persistent posterior neck and upper back pain for a month. Cervical radiographs and computed tomography revealed a series of sequential spinous process fractures from C7 to T3. The patient was prescribed analgesic medication and fitted with a cervical brace alongside extracorporeal shockwave therapy (ESWT) directed explicitly toward the upper back region, subsequently leading to a notable reduction in pain. Therefore, ESWT could be considered an additional method for pain management in patients with clay-shoveler's fractures.

Thermodynamic equations for the electric power and temperature in a turbo expander generator (TEG) using pressure energy in a natural gas line are derived. From the equations, it was shown that dominant factor is not the pressure difference but the pressure ratio. The high energy level in the inlet of TEG can be made from nearly no expense of electric energy input, which means TEG can be treated as one of newly available clean energy source. If a post heating method is chosen to heat up expanded natural gas, the usage of cold energy is possible without a refrigeration cycle. The combined TEG and refrigeration system enhances economic benefit much more.

The waste slurry generated from CMP process contains particulate and heavy metals. It is hard to treat the waste slurry by conventional treatment method because the particulates in the waste are too fine to be easily separated the solid from the waste for the purpose of water recycling. The investigation was focused on finding the optimum condition of coagulation with two different coagulants. When the solid content in the waste slurry solution was 0.1wt%, the optimal ranges of pH and PACl concentration were 4~6 and 20~50 mg/L, respectively. When the solid content was increased to 0.5wt%, the optimal condition was 4~5 for pH and 50~100 mg/L for PACl concentration.

CMP (Chemical mechanical polishing) is inevitable process to overcome $0.2{\mu}m$ wire thickness in semiconductor industry. In this study, effect of pressure to separate used CMP slurry into solid and liquid for recycle and reuse by ultrafiltration was investigated. Also, water quality after the ultrafiltration such as turbidity and TDS was evaluated. The material of membrane used in the study was PVDF. The used CMP contained 0.5% of solid content and then concentrated up to 18% by weight. The used CMP can not be concentrated higher than 18% because of viscosity and abrasion of pump. The tested feed pressures were 22.1, 29.4 and 36.8 psi. The results have shown that operating at 36.8 psi has advantages on operation time and total flux. The specific flux showed some variation at 1 to 15 of concentration factor but no difference after 15 of concentration factor. Mass balance of solid at initial stage of the operation showed some unbalance because of deposition of solid on the membrane, which was main reason to reduce flux. Turbidity was very stable at lower than 0.2NTU for 22.1 and 36.8 psi of feed pressure.

Most of weapon systems use aided navigation system which integrates inertial navigation and aiding sensors to compensate the INS errors increasing with the passage of time. Various aid sensors can be applied such as Global Navigation Satellite System (GNSS), radar, barometer, etc., but there might exist time delay caused by signal processing or transferring aid information. This time delay leads out-of-sequence measurements (OOSM) systems. Previously, optimal and suboptimal measurment update method for OOSM systems, where the time delay length are known, are proposed. However, previous algorithm does not guarantee the positive definite property of covariance matrix. In order to improve numerical stability for aided navigation using delayed-measurement, this paper proposes a new measurement covariance update algorithm be similar to Joseph-form in Kalman filter. Futhermore, we propose how to implement it in indirect feedback Kalman filter structure, which is commonly used in aided navigation systems, for time-delayed measurement systems. Simulation and vehicle test results show effectiveness of a proposed algorithm.
