This study investigates the application of management information systems to the quality of local government financial reports, especially the principle of transparency and the law of accountability, which have been measures of financial statement performance evaluation. The study was conducted in Enrekang Regency, Indonesia, which, based on the results of the examination, the Supreme Audit Board reported the status of Disclaimer, Fair with Exceptions, and Fair without Exceptions for three years each. This study used a sample of 35 respondents, finance department employees who worked on local government financial reports. Descriptive quantitative data were collected using a questionnaire instrument, then with the assistance of the Program Solution and Product Statistics (SPSS) Program, data were processed to test hypotheses. The results showed that the use of management information systems based on information and communication technology (ICT) had a significant influence on the quality of local government financial reports. The findings of this study indicate that the application of ICT-based management information systems affects the accountability and transparency of local government financial reports. This finding is reinforced by the use of the principles of government agility in the form of government apparatuses that apply responsive dexterity, flexibility agility, and competency agility.

Purpose: The purpose of this study was to identify the psychosocial working environment and mental health of financial workers, and analyze the impact of the former on the latter. Methods: Data of 257 financial clerks were extracted from the 2017 5th Korean Working Conditions Survey. Psychosocial working environment was divided into five fields: demands at work, work organizations, interpersonal relations, workplace violence, and working hour quality. Mental health included sleeping problems, psychological well-being, and job stress. Results: A total of 6.1% subjects reported sleep problems, 28.2% experienced poor psychological well-being, and 39.6% had job stress. More than half the subjects were exposed to tight deadlines, complex tasks, hiding feelings at work, fair treatment, fair distribution of work, colleagues' support, and managers' support. Tight deadlines, workplace violence, long working hours, hiding feelings at work, and managers' support had a significant impact on the mental health of financial clerks. Conclusion: Based on the results of this study, we propose that employers, workers, and health managers in the financial industry should work together to establish a respectful organizational culture, prevent long working hours through recruitment, and conduct programs to protect emotional health.

본 논문에서는 CBQ (Class Based Queuing) 알고리즘을 이용하여 DDoS 공격으로부터 메일 서버를 보호할 수 있는 효과적인 방법을 제안한다. 제안하는 방법에서는 메일 서버로 입력되는 트래픽을 중요한 메일 트래픽, 덜 중요한 메일 트래픽, 그 외의 공격의 가능성이 있는 알 수 없는 트래픽으로 구분하고 이들 각 트래픽에 서로 다른 대역폭을 할당함으로써 DDoS 공격 하에서도 정상적인 메일의 송신을 가능하게 한다. 제안하는 방법은 입출력 포트의 대역폭을 별도의 서비스(트래픽 클래스)마다 분산 할당하는 데에 유용한 가중치 사용 라운드 로빈 큐 스케줄링을 이용하는 WFHBD(Weighted Fair Hashed Bandwidth Distribution) 엔진을 고속 스위칭 프로세서를 내장한 임베디드 시스템에서 사용하고 실험을 통하여 DDoS 공격으로부터 메일 서버가 효율적으로 보호될 수 있음을 검증한다.

인터넷에서 서비스 품질을 제공하기 위해 대역폭에 대한 스케줄링 기술은 중요한요소 중 하나로서 많은 알고리즘이 개발되었다. 그러나 기존의 스케쥴링 알고리즘은 잉여 대역폭 분배에 있어 융통성을 제공하고 있지 않다. 이를 보완하여 잉여 대역폭 분배에 융통성을 제공하기 위해 DGPS(decoupled generalized processor sharing)가 제안되었지만/sup 〔1〕구현이 복잡하고 기존의 다양한 알고리즘에 쉽게 적용하기에는 어려움이 따랐다. 본 논문에서는 잉여 대역폭 분배의 융통성을 제공하고 동시에 DGPS의 문제점을 개선하여 기존의 기반 알고리즘에 자연스럽게 적용할 수 있는 스케쥴링 알고리즘을 제안하고 공평성을 분석하였다. 또한 시뮬레이션을 통해 성능을 검증하였다.

In this study, we introduce a new approach to Parallel Genetic Algorithms (PGA) which combines AHFCGA with crossover operator. As to crossover operators, we use three types of the crossover operators such as modified simple crossover(MSX), arithmetic crossover(AX), and Unimodal Normal Distribution Crossover(UNDX) for real coding. The AHFC model is given as an extended and adaptive version of HFC for parameter optimization. The migration topology of AHFC is composed of sub-populations(demes), the admission threshold levels, and admission buffer for the deme of each threshold level through succesive evolution process. In particular, UNDX is mean-centric crossover operator using multiple parents, and generates offsprings obeying a normal distribution around the center of parents. By using test functions having multimodality and/or epistasis, which are commonly used in the study of function parameter optimization, Experimental results show that AHFCGA can produce more preferable output performance result when compared to HFCGA and RCGA.

The effects of physical therapy on the knee joint dysfunction due to femur fracture C.E. Parkr, J. Baik, J.H. Rhee* One hundred and twenty - four knee joint dysfunction due to femur fractured treated, at dept of physical therapy Incheon christian hospital for 3 years since 1978were reviewed. Despite lack of progress note , the late results in sixty- eight cases of joint dysfunction were analysed clinically. The reselt obtained in this study are summerized as follow :1. Sex distribution of total patients surveyed showed that 73.5% in male, and26,5% in female. In age distribution, the most predominent age group was 21 ~.30years with 35.3%.2. About 56% of the cases were caused by traffic accident,3. The modalities of physical therapy suitable to each cases were applied, 94.1 %of all cases were treated with hot pack, 98.5 % active exercise, 73.5 % isometric exerclse .4. The improvement by physical therapy on knee joint dysfunction was classified into 4 grades and showed following results ; excellent 66.1%, good 26.5%, fair5.9% and poor 1,5% respectively.

Cosmology is a study to understand the origin, fundamental property, and evolution of the universe. Nowadays, many observational data of galaxies have become available, and one needs large-volume numerical simulations with good quality of the spatial distribution for a fair comparison with observation data. On the other hand, since galaxies' evolution is affected by both gravitational and baryonic effects, it is nontrivial to populate galaxies only by N-body simulations. However, full hydrodynamic simulations with large volume are computationally costly. Therefore, alternative galaxy assignment methods to N-body simulations are necessary for successful cosmological studies. In this talk, I would like to introduce the MBP-galaxy abundance matching. This novel galaxy assignment method agrees with the spatial distribution of observed galaxies between 0.1Mpc ~ 100Mpc scales. I also would like to introduce mock galaxy catalogs of the Horizon Run 4 and Multiverse simulations, large-volume cosmological N-body simulations done by the Korean community. Finally, I would like to introduce some recent works with those mock galaxies used to understand our universe better.

본 연구에서는, Markov 연쇄 모형에 의해 산정된 모의 일 강우량을 일 유출모형인 Tand 모형에 입력시켜 모의 일유출량을 산정함으로써 저수유량계열을 확장하는 방법을 개발하였다. 또한, 모의된 일 유량계열로부터 지속기간별 연 최저치 계열을 작성하였으며, 지속기간별 연 최저치계열에 대한 빈도분석을 시행하였다. 분석에 사용된 분포형은 Lognormal-2, Lognormal-3, Gamma-2, Gamma-3, LogGamma-3, Gumbel-2, Weibull-2 분포이었으며, 모수추정은 모멘트법과 최우도법을 사용하였다. Kolmogorov - Sminorv 검정방법으로 지속기간별 연 최저치 계열에 적합한 확률분포형을 결정하고, 용담댐 지점을 대상으로 하여 지속기간별 갈수 빈도곡선을 산정하였다. 본 연구에서 제안된 방법을 적용하면 과거 저수 유량계열의 통계적 특성을 잘 나타내는 일 유량의 모의가 가능 하여, 갈수유량계열 자료가 빈곤한 유역에서 확률 갈수량을 추정하는데 유용하리라고 판단된다.
