Purpose Issues related to information security have been a crucial topic of interest to researchers and practitioners in the IT/IS field. This study develops a research model based on a Structure-Conduct-Outcome (SCO) framework for the social exchange relationship between employees and organizations regarding information security. Design/methodology/approach In applying an SCO framework to information security, structure and conduct are activities imposed on employees within an organizational context; outcomes are activities that protect information security from an employee. Data were collected from 438 employees working in manufacturing and service firms currently implementing an information security policy in South Korea. Structural equation modeling (SEM) with AMOS 22.0 is used to test the validation of the measurement model and the proposed casual relationships in the research model. Findings The results demonstrate support for the relationships between predicting variables in organization structure (security policy and physical security system) and the outcome variables in organization conduct (top management support, security education program, and security visibility). Results confirm that the three variables in organization conduct had a positive effect on individual outcome (security knowledge and compliance intention).

폐기물 처분장으로부터 인간생활 환경으로까지 침출수가 어떤 방향과 속도로 유출될 것인가하는 것은 많은 사람의 관심의 대상이며, 어떤 처분장 설계가 관련 규제법을 효과적으로 만족시키고 있는가를 알아야 할 필요가 있다. 침출수이동에 관한 해석방법을 제심함에 있어, 화력발전의 결과로 생기는 석탄재의 폐기 방식중 두 가지 대표적인 방식인 매립방식과 연못방식에 대한 평가를 예시하였다. 관련 규제법으로는 "100/100 룰", 즉, 처분장으로부터 100ft(30.5cm) 떨어진 곳까지 침출수가 도달하는데 100년이상 걸려야 한다는 제약조건을 적용하였다. 수치해석에 의한 지하수 유동방정식의 해는 압력수두 분포와 유동량(flux)에 관한 정보를 제시하여 주었으며, 유적선(pathline)의 해석은 침출수 이동 경로와 시간에 관한 예측을 가능케 하였다.을 가능케 하였다.

3상형 박동류는 인체 순환계 혈류의 일반적인 형태이다. 심혈관계의 여러 가지 상황을 모의하려면 이러한 3상형 박동류를 만들어 내는 것이 필수적이다. 본 연구에서는 3상형 박동류를 모의하기 위해서 전기유압식 좌심실보조기를 유리 팬텀과 고무 튜브와 같이 사용하였으며 혈류 모의 시스템의 제어변수를 선정하고 각 변수들의 변화에 대한 영향을 도플러 초음파를 이용하여 관찰하였다. 본 실험의 결과 협착 후위부 탄성과 지연시간이 3상형 혈류를 생성하는 중요한 요인이었다. 본 실험의 결과들은 다양한 혈류 운동을 모의할 수 있게 해 줌으로써 심혈관계의 여러현상을 설명하는 유용한 도구가 될 수 있을 것으로 기대된다.

Elastic-plastic fracture toughness $J_{1c}$ can be used as an effective design criterion in elastic plastic fracture mechanics. Most of these systems are operated at high temperature and $J_{1c}$ values are affected by temperature. therefore, the $J_{1c}$ valuse at high temperature must be determined for use of integrity evaluation and designing of such systems. Elastic-plastic fracture toughness $J_{1c}$ tests were performed on SA516 carbon steel plate and test results were analyzed according to ASTM E 813-8, ASTM 1813-89. Safety and integrity are required for reactor pressure vessels vecause pthey are operated in high temperature. there are single specimen method, which used as evaluation of safety and integrity for reactor pressure vessels. In this study, elastic-plastic fracture toughness$(J_{1c})$ and $J-\Delta{a}$ of SA 516/70 steel used as reactor pressure vessel steel are measured and evaluated at room Temperature, $150^{\circ}C$, $250^{\circ}C$ and $370^{\circ}C$ according to unloading compliance method.

정보보안은 여전히 많은 조직에서 해결해야할 중요한 문제 중 하나이다. 특히 어떻게 조직 구성원들의 보안행위를 유도할 것이며, 내부인력에 의한 사고를 줄일 수 있는지는 여전히 정보보안 분야에서 탐색되어야할 문제로 남아있다. 본 연구는 선행연구에서 제시한 정보보안 대책이 상황에 따라 다른 결과를 나타나는 이유를 설명하고자 한다. 이를 위해 위험보상 이론을 기반으로 연구모형을 수립하고 실증적으로 분석하였다. 분석 결과 정보보안 대책과 조직 구성원들의 보안정책준수의도 간의 관계는 시스템의 취약성에 의해 조절되는 것으로 나타났다. 본 결과는 위험보상이론의 기본 가정과 반대된다. 반면 시스템 품질의 조절효과는 없는 것으로 나타났다.

Due to its profound intestinal first-pass metabolism, oral eperisone hydrochloride produces a very low bioavailability and a very short muscle relaxant activity. To improve the efficacy and compliance of eperisone, we designed a new dosage form, the transdermal patch and evaluated the muscle relaxant effects of this patch in rats. The muscle relaxant activity was assessed by measurement of forelimb grip strength and hanging test in rats. The transdermal patch of eperisone hydrochloride showed significant muscle relaxant activity at 0.5, 1.5 and 3 cm$^2$/200 g rat (1.39, 4.17 and 8.33 mg of eperisone hydrochloride/kg, respectively) in a dose-dependent manner and the effects were lasted over 24 hours. The oral eperisone hydrochloride showed significant activity at 12.5, 25 and 50 mg/kg in a dose-dependent manner but the activity was within 1 or 2 hours after administration. These results suggest that the eperisone hydrochloride is absorbed efficiently from transdermal patch and the patch can exert potent and long-lasting muscle relaxant activity. This transdermal patch will increase the efficacy and compliance in the clinical use of eperisone hydrochloride.

This study proposes a new algorithm which performs a production simulation under various constraints and maintains computational efficiency. In order to consider the environmental and operational constraints, the proposed algorithm is based on optimization techniques formulated in LP form In the algorithm, "system characteristic constraints" reflect the system characteristics such as LDC shape, unit loading order and forced outage rate. By using the concept of Energy Invariance Property and two operational rules i.e. Compliance Rule for Emission Constraint, Compliance Rule for Limited Energy of Individual Unit, the number of system characteristic constraints is appreciably reduced. As a solution method of the optimization problem, the author uses Karmarkar's method which performs effectively in solving large scale LP problem. The efficiency of production simulation is meaningful when it is effectively used in power system planning. With the proposed production simulation algorithm, an optimal expansion planning model which can cope with operational constraints, environmental restriction, and various uncertainties is developed. This expansion planning model is applied to the long range planning schemes by WASP, and determines an optimal expansion scheme which considers the effect of supply interruption, load forecasting errors, multistates of unit operation, plural limited energy plants etc.

The biochemical oxygen demand (BOD) test is widely used to determine the pollution strength of water, to evaluate the performance of wastewater treatment plants and to judge compliance with discharge permits. However, nitrification is a cause of significant errors in measuring BOD, particularly when a large population of nitrifying organisms is existing in water such as effluents from biological treatment plants. In order to investigate the amount of nitrogenous oxygen demand (NOD), BOD with and without inhibitor was measured as samples in the biological treatment plants. About 81% of effluent BOD from the biological treatment plant used in this experiment was comprised of NOD. In the case of influents, the NOD accounted for about 9% of BOD. The inhibited 5-day BOD (Carbonaceous BOD) test must be considered in evaluating the performance of wastewater treatment plant and judging compliance with discharge permit limitations.

This paper presents and tests a conceptual model of Technology Acceptance Model(TAM) that explains perceived usefulness, perceived ease of use, organizational commitment and turnover intention in terms of psychological commitment in mandatory environments. The model focuses on psychological commitment(Kelman's internalization, identification, compliance) as the primal of predictor of perceived usefulness, perceived ease of use and organizational commitment we discuss our current understanding of technology acceptance, as well as the notion of mandated use. The results and implications of the research are as follows. First, organizational commitment negatively influence turnover intention in mandatory environment. Second, perceived usefulness positively influence organizational commitment in mandatory environments. Third, psychological commitment positively influence organizational commitment, perceived usefulness and perceived ease of use in mandatory environments. Fourth, perceived ease of use positively influence perceived usefulness in mandatory environments. Through this research, psychological commitment is a strong determinant of technology acceptance in mandatory environments. These findings advance theory and contribution to the foundation for future research aimed at improving our understanding of user adoption behavior in mandatory environments.
