This study was initiated to investigate the essential skill factors for system designers in order to build the right information systems. The predicted variables are mathematical modeling skill, verbal modeling skill, general IT knowledge, and general business knowledge. The test was administrated to 43 students majoring in Management Information Systems (MIS) at Hannam University, South Korea. In this study, we used Pearson Correlation Analysis to test the relationships among variables. Overall, our study suggested that there is a strong positive relationship between mathematical and verbal skills and IS modeling ability. A marginal positive relationship between the general IT knowledge and IS modeling ability was also found. Unexpectedly, there was no significant relationship between general business knowledge and IS modeling ability.

There are lots of indices that define the intensity of East Asian summer monsoon (EASM) in climate systems. This paper assesses the prediction skill for EASM indices in a Global Seasonal Forecasting System (GloSea5) that is currently operating at KMA. Total 5 different types of EASM indices (WNPMI, EAMI, WYI, GUOI, and SAHI) are selected to investigate how well GloSea5 reproduces them using hindcasts with 12 ensemble members with 1~3 lead months. Each index from GloSea5 is compared to that from ERA-Interim. Hindcast results for the period 1991~2010 show the highest prediction skill for WNPMI which is defined as the difference between the zonal winds at 850 hPa over East China Sea and South China Sea. WYI, defined as the difference between the zonal winds of upper and lower level over the Indian Ocean far from East Asia, is comparatively well captured by GloSea5. Though the prediction skill for EAMI which is defined by using meridional winds over areas of East Asia and Korea directly affected by EASM is comparatively low, it seems that EAMI is useful for predicting the variability of precipitation by EASM over East Asia. The regressed atmospheric fields with EASM index and the correlation with precipitation also show that GloSea5 best predicts the synoptic environment of East Asia for WNPMI among 5 EASM indices. Note that the result in this study is limited to interpret only for GloSea5 since the prediction skill for EASM index depends greatly on climate forecast model systems.

Due to exponentially growing threats of cyber attacks, many organizations have begun to recognize the importance of information security. There is an explosion in demand for experienced ISMs(Information Security Managers) and ISSDs(Information Security System Developers). To educate ISMs and ISSDs, identifying the specific knowledge and skill for information security professional is critical. This paper identifies 15 items of knowledge and skill for ISMs and ISSDs using a simplified Delphi technique and categories them. The results of this paper could be used in determining what kinds of knowledge and skill should be included in the curriculum of information security programs.

청소년의 봉사활동이 체험활동으로서의 기능과 건전한 인격형성 및 공동체 의식 함양과 청소년 리더십 생활기술 능력 향상에 긍정적인 영향을 미치기도 하지만, 봉사활동이 결과만을 입시에 반영하도록 함으로써 자원봉사활동의 본래의 목적이 퇴색되어가고 있다. 본 연구에서는 청소년 자원봉사활동의 참여동기(이타적 참여동기, 이기적 참여동기)가 청소년 리더십 생활기술 능력(인간관계기술, 그룹활동기술, 학습능력기술, 자기이해기술)과 자원봉사 만족도에 미치는 영향을 분석하고자 설문조사를 실시하였으며, 최종적으로 222개의 표본을 분석에 사용하였다. 그 결과에 의하면, 첫째, 청소년의 자원봉사활동의 이타적 참여동기가 리더십 생활기술능력과 자원봉사 만족도에 긍정적으로 유의한 영향을 미치는 것으로 나타났다. 둘째, 청소년의 자원봉사활동의 이기적 참여동기는 리더십 생활기술능력에 유의한 영향을 미치지 않는 것으로 나타났으며, 자원봉사 만족도에는 부정적인 영향을 미치는 것으로 나타났다.

A full automatic interpretation of awake electroencephalogram (EEG) had been developed by the authors and presented at the past KACCs in series. The automatic EEG interpretation consists of four main parts: quantitative EEG interpretation, EEG report making, preprocessing of EEG data and adaptable EEG interpretation. The automatic EEG interpretation reveals essentially the same findings as the electroencephalographer's (EEG's), and then would be applicable in clinical use as an assistant tool for EEGer. The method had been developed through collaboration works between the engineering field (Saga University) and the medical field (Kyoto University). This work can be understood as an artificial realization of human expert skill. The procedure for the artificial realization was summarized in a methodology for artificial realization of human skill which will be applicable in other fields of systems control.

The necessity of the prediction on the Seasonal-to-Subseasonal (S2S) timescale continues to rise. It led a series of studies on the S2S prediction models, including the Global Seasonal Forecasting System Version 5 (GloSea5) of the Korea Meteorological Administration. By extending previous studies, the present study documents sea surface temperature (SST) prediction skill around the Korean peninsula in the GloSea5 hindcast over the period of 1991~2010. The overall SST prediction skill is about a week except for the regions where SST is not well captured at the initialized date. This limited prediction skill is partly due to the model mean biases which vary substantially from season to season. When such biases are systematically removed on daily and seasonal time scales the SST prediction skill is improved to 15 days. This improvement is mostly due to the reduced error associated with internal SST variability during model integrations. This result suggests that SST around the Korean peninsula can be reliably predicted with appropriate post-processing.

In this paper, we proposed an adaptive skill element based on error signal. We assume that human progress their skills of actions based on errors, then an inverse dynamic of human motion have to changes. Human controller consists from feedback element (FB) and feed forward element (FF) and their elements cooperate to control actions. Under the assumption, we vary the connection of FF and FB by error signal. We propose the index function for change of a skill parameter. From results of the numerical simulations for the varying skill parameter with index function, we consider that the position error given by our vision changes the skill element and we confirm that the position error is the one of the estimate function for the improvement in our skill.
