The investment agreement prepared at the beginning of inter-Korean economic cooperation in 2000 can be evaluated as very ineffective as a product of mutual political and diplomatic compromise rather than an effective protection for our investment assets. South Korean companies suffered a lot of losses due to the freezing of assets in the Geumgang mountain district and the closure of the Kaeseung Industrial Complex, but they did not receive practical damage relief due to institutional vulnerabilities. Currently, North Korea is under international economic sanctions of the UN Security Council, so it is true that the resumption of inter-Korean economic cooperation is far away, but North Korea's human resources and geographical location are still attractive investment destinations for us. Therefore, if strained relations between the two Koreas recover in the future and international economic sanctions on North Korea are eased, Korean companies' investment in North Korea will resume. However, the previous inter-Korean investment agreement system was a fictional systemthat was ineffective. Therefore, if these safety devices are not reorganized when economic cooperation resumes, unfair damage to Korean companies will be repeated again. The core of the improved investment guarantee system is not a bilateral system between the two Koreas, but the establishment of a multilateral system through North Korea's inclusion in the international economy. Specifically, it includes encouraging North Korea to join international agreements for the execution of arbitration decisions, securing subrogation rights through membership of international insurance groups such as MIGA, creating matching funds by international financial organizations. Through this new approach, it will be possible to improve the safety of Korean companies' investment in North Korea, and ultimately, it will be necessary to lay the foundation for mutual development through economic cooperation between the two Koreas.

댐 건설은 홍수 및 가뭄에 대응하기 위한 구조적 방법으로써 우리나라와 같이 지표수에 의존적인 지역에서는 가용 수자원을 확보하기 위한 확실한 수단으로 활용되어왔다. 신규 댐의 건설은 대상 하천의 수리학적 특성에 큰 변화를 야기할 수 있으며, 댐의 안정성 및 하천의 하도보호를 위해 댐 주변의 수리적 특성의 변화에 대해서도 사전에 인지하여 설계 시 반영할 필요가 있다. 수공구조물 신설에 따라 변화되는 수리학적 특성을 분석하는 방법으로는 그 수단에 따라 상사법칙을 적용한 수리모형실험과 수치기법을 활용한 수치모형실험으로 나눌 수 있다. 본 연구에서는 수리모형실험을 통한 실험적 방법을 이용하여 댐 상하류 구간의 수리학적 특성을 분석하였다. 해당 실험은 한국농어촌공사 농어촌연구원의 대형수리모형실험시설에서 수행되었다. 적용대상 댐의 제원은 높이 약 70m, 길이 약 230m이며, 폭 55m의 여수로를 포함하는 구조로 설정하였다. 수리모형은 Froude 상사법칙을 적용하여 1/30 규모로 축소하였으며, 콘크리트 및 아크릴 재료를 이용하여 제작되었다. 댐 모형이 설치되는 하천구간은 댐 구조물을 포함하여 실규모를 기준으로 흐름방향으로 약 800m, 하폭방향으로 약 450m의 범위를 포함하도록 설계되었으며, 하류구간에 사행하천이 존재하는 것이 특징이다. 본 실험에서 유량은 총 12개의 펌프를 이용하여 공급되었으며, 최대 4cms에 해당하는 유량공급이 가능하도록 설계하였다. 공급유량은 정교한 절차에 의해 보정된 전자식 유량계를 통해 통제되었으며, 사용된 유량계의 허용오차는 약 0.5% 수준인 것으로 나타났다. 수위 측정은 오차범위 0.05mm 수준의 초음파 수위측정기를 이용하였으며, 유속측정은 약 0.5cm/s의 정확도를 지닌 3차원 전자기 유속계를 이용한 접촉식 측정과 흐름구조 가시화를 위한 비접촉식 입자추적기법을 병행하였다. 실험조건은 실규모 기준으로 방류량 3,000~5,000cms에 대해 수행하였으며, 각 방류량별 댐 상하류의 흐름패턴에 대해 정량적으로 분석하였다.

Based on the social control theory, this study intends to find out the influential factors of organizational members' information security policy compliance (ISPC). Survey data from 195 military officers were analyzed to examine the effect of ethical disposition (morality, responsibility, the perceived value of ethical education) and perceived work environment (relationships with supervisors, overwork, and pay satisfaction) on ISPC attitude, ISPC intention, and turnover intention. The results of partial least squares structural equation modeling (PLS-SEM) show that ethical dispositions affect ISPC attitude and that work environments (except for pay satisfaction) affect turnover intention. In addition, ISPC attitude significantly mediates relations between ethical disposition and ISPC intention, between relationships with supervisors and ISPC intention, and between turnover intention and ISPC intention. These findings suggest that ethical disposition factors can predict an individual's security awareness level, and the ISPC attitude is a significant variable in the organizational security context.

The dynamic stability of railway vehicle has been one of the important issues in railway safety. The dynamic simulator has been used in the study about the dynamic stability of railway vehicle and wheel/rail interface optimization. Especially, a small scale simulator has been widely used in the fundamental study in the laboratory instead of full scale roller rig which is not cost effective and inconvenient to achieve diverse design parameters. But the technique for the design of the small scale simulator about the dynamic characteristics of the wheel-rail system and the bogie system has not been well developed in Korea. Therefore, the research using the small-scaled derailment simulator and the 1/5 scaled bogie has been conducted. In this paper, we did running stability test of 1/5 scaled bogie using small-scaled derailment simulator. Also, for the operation of the small scaled simulator, it is required to investigate the performance and characteristics of the simulator system. This could be achieved by a comparative study between an analysis and an experiment. This paper presented the analytical model which could be used for verifying the test results and understanding of the physical behavior of the dynamic system comprising the small- scaled derailment simulator and the 1/5 scaled bogie.

This study is about the factors affecting organizational effectiveness and to suggest implications for encouraging organizational effectiveness. The conditional process model was analyzed with transformational leadership as an independent variable, educational service quality as a mediator, organizational effectiveness as a dependent variable, and trust as a moderator. The data collected from the financial institutions were analyzed using SPSS v22.0 and PROCESS macro v3.4. As a result, transformational leadership has a (+) effect on educational service quality, and educational service quality has a (+) effect on organizational effectiveness. Except for the relationship between charisma and innovative behavior, transformational leadership affect organizational effectiveness. Excluding the relationship between charisma and innovative behavior, educational service quality mediate between transformational leadership and organizational effectiveness. Trust only moderates between educational service quality and innovative behavior. Trust moderated the mediating effect of educational service quality between transformational leadership and innovative behavior. The results suggest the importance of education service quality management in a non-face-to-face working environment and the importance of individual consideration in innovative actions.

This study was conducted to determine the levels of job stress, as well as its association with psychosocial factors (type A behavior pattern, locus of control, and self-esteem). Self-administered questionnaires were given to 634 clerical public officers in the C Provincial Office between February 18 and Mar. 10, 2013. As a result, the job stress levels of the subjects was significantly different according to age, sex, educational level, marital status, job position, job career, satisfaction in job life, smoking, alcohol drinking, sleeping time, type A behavior pattern, locus of control, and self-esteem. Regarding the correlation of job stress and psychosocial factors, the level of job demand was negatively correlated with the internal locus of control. The decision latitude was negatively correlated with the type A behavior pattern, internal locus of control and self-esteem. Supervisor support was negatively correlated with the external locus of control. In hierarchial multiple regression analysis, the affecting factors to the job stress selected variables, such as age, subjective health status, job position, overtime work, experience of sick absence, satisfaction in work, sleeping time, leisure time, visiting out-patient department, type A behavior pattern, locus of control, and self-esteem, and the explanatory powers of these factors was 32.1%. In particular, the factors related to the psychosocial factors (type A behavior pattern, locus of control, self-esteem) were strongly related to the job stress, increasing the explanation of factors up to 15.0%.
